DETAILED DESCRIPTION

The present disclosure will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of different embodiments of this disclosure are presented herein for purpose of illustration and description only, and it is not intended to limit the scope of the present disclosure.

Please refer to FIG. 1 and FIG. 2. In one exemplary embodiment of the present disclosure, the pressure-adjustable brassiere pad 1 includes a main body 2 and a gas collection actuator 3. The main body 2 includes an inner surface layer 21, an outer surface layer 22, and a gas bag layer 23. The gas bag layer 23 is enclosed between the inner surface layer 21 and the outer surface layer 22. The gas bag layer 23 has a gas passage 24. The gas passage 24 has a connection end 24a, and the connection end 24a penetrates through and extends out from the main body 2.

It should be noted that, in the embodiment(s) of the present disclosure, the cloth material of the outer surface layer 22 and the cloth material of the inner surface layer 21 may be different, but is not limited thereto. The cloth material can be changed with any suitable materials depending on the actual implementation situations. The appearance and arrangement of the gas bag layer 23 may also have various changes. For example, the gas bag layer 23 may be a half-moon-shaped (arced shaped), occupying ⅓ part of the cup of a brassiere, but is not limited thereto. In other embodiments, the gas bag layer 23 may also be in the form of a 1/2 cup of a brassiere, that is, the gas bag layer 23 occupies half of the cup of the brassiere, but is not limited thereto. Certainly, in other embodiments, the gas bag layer 23 may be in a full-cup form, that is, the gas bag layer 23 substantially occupies the whole cup of the brassiere. It can be seen that the shape, location, numeral range, etc., of the gas bag layer 23 may be arbitrarily changed according to the actual implementation situations, and is not limited to the foregoing. In this embodiment, the gas collection actuator 3 is detachably connected to the connection end 24a of the gas passage 24, but is not limited thereto. Moreover, in some other embodiments, the gas collection actuator 3 may be firmly connected to the connection end 24a of the gas passage 24, but the configuration is not limited thereto. By connecting the gas collection actuator 3 to the connection end 24a, the gas collection actuator 3 can supply the gas into the gas bag layer 23 or discharge the gas out of the gas bag layer 23 through the connection end 24a of the gas passage 24. Therefore, the internal pressure of the gas bag layer 23 can be adjusted. In this way, the user can adjust the volume and pressure of the gas bag layer 23 in the main body 2 through the gas collection actuator 3, so that the hardness, appearance, and support strength of the main body 2 can meet the requirements of the user, thereby achieving a desired effect for supporting the breast of the wearer. Moreover, since the hardness, appearance, and support strength can be adjusted according to the ideal state required by different users, the effect of a stable supporting can be achieved as well.

Please refer to FIG. 1. In this embodiment, the gas collection actuator 3 includes a gas transmitter 31, a transmission channel 32, a gas pressure detector 33, a control module 34, an inlet on-off valve 35a, and an outlet on-off valve 35b. The gas transmitter 31 provides the gas bag layer 23 of the main body 2 with gas through the transmission channel 32 so as to adjust the internal pressure of the gas bag layer 23. The control module 34 controls the operation of the transmitter 31 and the gas pressure detector 33. The gas pressure detector 33 detects the internal pressure of the gas bag layer 23 so as to monitor the internal pressure and notify the control module 34 to control the operation of the gas transmitter 31. That is, in this embodiment, when the internal pressure of the gas bag layer 23 reaches a predetermined value, the gas pressure detector 33 notifies the control module 34 to stop the operation of the gas transmitter 33, thereby achieving the object of intelligent control. The user can adjust the predetermined value of the gas pressure detector 33 through the control module 34, so that the user can adjust the inflation volume of the gas bag layer 23, thereby controlling the operation time of the gas transmitter 31. Hence, the hardness, appearance, and support strength of the main body 2 can be adjusted to meet the requirements of the user and the effect of intelligent power saving can be achieved as well. Moreover, the operation of the inlet on-off valve 35a and the outlet on-off valve 35b are controlled by the control module 34. The inlet on-off valve 35a is in communication with the gas inlet end of the gas transmitter 31. When the inlet on-off valve 35a is opened, the gas transmitter 31 is capable of guiding a gas outside of the gas collection actuator 3 into the gas collection actuator 3. The outlet on-off valve 35b is in communication with the discharge end of the gas transmitter 31. When the outlet on-off valve 35b is opened, the gas transmitter 31 is capable of discharging a gas inside the gas collection actuator 3 out of the gas collection actuator 3.

Please refer to FIG. 1, FIG. 2, and FIG. 3. In this embodiment, the gas transmitter 31 is in communication with the connection end 24a of the gas passage 24 through the transmission channel 32. The gas transmitter 31 includes a micro pump 311, a gas collection valve base 312, a chamber plate 313, and a valve membrane 314. One surface of two surfaces of the gas collection valve base 312 is recessed to form a gas collection trough 312a, and the gas collection trough 312a is in communication with transmission channel 32. A first gas collection chamber 312b and a first pressure relief chamber 312c are disposed on the other surface of the two surfaces of the gas collection valve base 312. A gas collection through hole 312d is connected between the gas collection trough 312a and the first gas collection chamber 312b, so that the gas collection trough 312a is in communication with the first gas collection chamber 312b. The first gas collection chamber 312b and the first gas relief chamber 312c are disposed apart from each other and are disposed on the other surface of the two surfaces of the gas collection valve base 312. A connection channel 312e is connected between the first gas collection chamber 312b and the first gas relief chamber 312c, so that the first gas collection chamber 312b is in communication with the first gas relief chamber 312c. A gas collection valve base convex portion 312f is disposed in the first gas relief chamber 312c, and a gas relief through hole 312g is formed in a central portion of the gas collection valve base convex portion 312f. One end of two ends of the gas relief through hole 312g is served as the discharge end of the gas transmitter 31 and is in communication with the outlet on-off valve 35b (as shown in FIG. 1). The other end of the gas relief through hole 312g is capable of being in communication with the first gas relief chamber 312c. Thus, by opening the outlet on-off valve 35b, the gas can be discharged out through the gas relief through hole 312g, thereby completing the gas-released operation.

In this embodiment, the chamber plate 313 is placed on the gas collection valve base 312. One side of the chamber plate 313 is the gas inlet end of the gas transmitter 31, and the gas inlet end is in communication with the inlet on-off valve 35a (as shown in FIG. 1). A second gas collection chamber 313a and a second gas relief chamber 313b are disposed on a surface of the chamber plate 313 facing the gas collection valve base 312. The second gas collection chamber 313a corresponds to the first gas collection chamber 312b, and the second gas relief chamber 313b corresponds to the first gas relief chamber 312c. A chamber plate convex portion 313c is disposed in the second gas collection chamber 313a. A surface of the chamber plate 313 opposite to the second gas collection chamber 313a and the second gas relief chamber 313b is recessed to form a connection chamber 313d. The micro pump 311 is placed on the chamber plate 313 so as to cover the connection chamber 313d. The chamber plate 313 has a plurality of connection holes 313e. The connection holes 313e are connected between the connection chamber 313d and the second gas collection chamber 313a and are connected between the connection chamber 313d and the second gas relief chamber 313b. The valve membrane 314 is disposed between the gas collection valve base 312 and the chamber plate 313, so that the valve membrane 314 abuts against the gas collection valve base convex portion 312f to close the gas relief through hole 312g. The valve membrane 314 has a valve hole 314a at a position where the valve membrane 314 abuts against the chamber plate convex portion 313c, so that the valve hole 314a is closed.

Please refer to FIG. 5A, FIG. 5B, and FIG. 6A. In this embodiment, an inlet plate 3111, a resonance sheet 3112, a piezoelectric actuator 3113, a first insulation plate 3114, a conductive plate 3115, and a second insulation plate 3116 are sequentially stacked with each other to form the micro pump 311.

In this embodiment, the inlet plate 3111 has at least one inlet hole 3111a, at least one convergence channel 3111b, and a convergence chamber 3111c. The inlet hole 3111a is in communication with the inlet on-off valve 35a (as shown in FIG. 1) so as to guide the gas to flow into the micro pump 311. The inlet hole 3111a corresponds to the at least one convergence channel 3111b, so that the inlet hole 3111a is in communication with the convergence channel 3111b. The inlet hole 3111a is in communication with the convergence chamber 3111c through the convergence channel 3111b, so that the gas introduced by the inlet hole 3111a is converged at the convergence chamber 3111c. In this embodiment, the number of the inlet hole 3111a and the number of the convergence channel 3111b are the same. The number of the inlet hole 3111a and the number of the convergence channel 3111b may be both four, but is not limited thereto. The four inlet holes 3111a are respectively in communication with the four convergence channels 3111b, and the four convergence channels 3111b are in communication with the convergence chamber 3111c.

In this embodiment, the resonance sheet 3112 is disposed on the inlet plate 3111, and the resonance sheet 3112 has a perforation 3112a, a movable portion 3112b, and a fixed portion 3112c. The perforation 3112a is disposed at the center portion of the resonance sheet 3112 and corresponds to the convergence chamber 3111c of the inlet plate 3111. The movable portion 3112b is disposed at the periphery of the perforation 3112a and corresponds to the convergence chamber 3111c of the inlet plate 3111. The fixed portion 3112c is disposed at the periphery of the resonance sheet 3112 and is used to be attached to the inlet plate 3111.

In this embodiment, the piezoelectric actuator 3113 is disposed on the resonance sheet 3112, and the piezoelectric actuator 3113 includes a suspension plate 3113a, an outer frame 3113b, at least one supporting element 3113c, a piezoelectric element 3113d, at least one gap 3113e, and a protruding portion 3113f. In this embodiment, the suspension plate 3113a is in square shape. It is understood that, the reason why the suspension plate 3113a adopts the square shape is that, comparing with a circle suspension plate having a diameter equal to the side length of the square suspension plate 3113a, the square suspension plate 3113a has an advantage of saving electricity. The power consumption of a capacitive load operated at a resonance frequency may increase as the resonance frequency increases, and since the resonance frequency of a square suspension plate 3113a is much lower than that of a circular suspension plate, the power consumption of the square suspension plate 3113a is relatively low as well. Consequently, the square design of the suspension plate 3113a used in one or some embodiments of the present disclosure has the benefit of power saving. In this embodiment, the outer frame 3113b is disposed around the periphery of the suspension plate 3113a. At least one supporting element 3113c is connected between the suspension plate 3113a and the outer frame 3113b to provide a flexible support for the suspension plate 3113a. In this embodiment, the piezoelectric element 3113d has a side length, which is shorter than or equal to a side length of the suspension plate 3113a. The piezoelectric element 3113d is attached to a first surface 331a of the suspension plate 3113a so as to drive the suspension plate 3113a to bend and vibrate when the piezoelectric element 3113d is applied with a voltage. At least one gap 3113e is formed among the suspension plate 3113a, the outer frame 3113b, and the at least one connecting element 3113c, and the at least one gap 3113e is provided for the gas to flow therethrough. The protruding portion 3113f is disposed on a second surface of the suspension plate 3113a opposite to the first surface of the suspension plate 3113a where the piezoelectric element 3113d is attached. In this embodiment, the protruding portion 3113f may be a convex structure protruding out from and integrally formed with the second surface of the suspension plate 3113a opposite to the first surface of the suspension plate 3113a which the piezoelectric element 3113d is attached by performing an etching process on the suspension plate 3113a.

Please refer to FIG. 6A. In this embodiment, a chamber space 3117 is formed between the suspension plate 3113a and the resonance sheet 3112. The chamber space 3117 can be formed by filling a material between the resonance sheet 3112 and the outer frame 3113b of the piezoelectric actuator 3113, such as conductive adhesive, but not limited thereto. By filling a material between the resonance sheet 3112 and the suspension plate 3113a, a certain distance can be maintained between the resonance sheet 3112 and the suspension plate 3113a to form the chamber space 3117, by which the gas can be guided to flow more quickly. Further, since an appropriate distance is maintained between the suspension plate 3113a and the resonance sheet 3112, the interference raised by the contact between the suspension plate 3113a and the resonance sheet 3112 can be reduced, so that the generation of noise can be decreased as well. In other embodiments, the needed thickness of the conductive adhesive between the resonance sheet 3112 and the outer frame 3113b of the piezoelectric actuator 3113 can be decreased by increasing the height of the outer frame 3113b of the piezoelectric actuator 3113. Accordingly, during the forming process at the hot pressing temperature and the cooling temperature, the situation that the actual spacing of the chamber space 3117 being affected by the thermal expansion and contraction of the conductive adhesive can be avoided, thereby decreasing the indirect effect of the hot pressing temperature and the cooling temperature of the conductive adhesive on the entire structure of the micro pump 311. Moreover, the height of the chamber space 3117 also affects the transmission efficiency of the micro pump 311. Therefore, it is important that a fixed height of the chamber space 3117 should be maintained for the purpose of achieving stable transmission efficiency with the micro pump 311.

Please refer to FIG. 6B. In some other embodiments, the suspension plate 3113a can be extended out by a certain distance by stamping. The extension distance can be adjusted by at least one supporting element 3113c between the suspension plate 3113a and the outer frame 3113b so as to make the surface of suspension plate 3113a and the surface of the outer frame 3113b be non-coplanar. Furthermore, a few amount of filling material (such as the conductive adhesive) is applied on the assembly surface of the outer frame 3113b, and the piezoelectric actuator 3113 is assembled to the resonance sheet 3112 by attaching the piezoelectric actuator 3113 onto the fixed portion 3112c of the resonance sheet 3112 through hot pressing. By stamping the suspension plate 3113a of the piezoelectric actuator 3113 to form the chamber space 3117, the chamber space 3117 can be obtained by directly adjusting the extension distance of the suspension plate 3113a of the piezoelectric actuator 3113, which effectively simplifies the structural design of the chamber space 3117, and also simplifies the manufacturing process and shortens the manufacturing time of the chamber space 3117.

In this embodiment, the chamber space 3114, the conductive plate 3115, and the second insulation plate 3116 are all thin sheets with a frame like structure, and are sequentially stacked and assembled with each other to form the main structure of the micro pump 311.

Please refer to FIG. 6A. In this embodiment, the inlet plate 3111, the resonance sheet 3112, the piezoelectric actuator 3113, the first insulation plate 3114, the conductive plate 3115, and the second insulation plate 3116 may all be made by the MEMS surface micromachining technology. Thus, the size of the micro pump 311 can be reduced so as to form a microelectromechanical systems (MEMS) micro pump 311.

FIG. 6C to FIG. 6E illustrate schematic cross-sectional views showing the micro pump 311 according to the exemplary embodiment at different operation steps. In this embodiment, as shown in FIG. 6C, the piezoelectric element 3113d of the piezoelectric actuator 3113 deforms after being applied with a driving voltage, and the piezoelectric element 3113d drives the suspension plate 3113a to move away from the inlet plate 3111. Thus, the volume of the chamber space 3117 is increased and a negative pressure is generated inside the chamber space 3117, thereby drawing the gas in the convergence chamber 3111c into the chamber space 3117. At the same time, owing to the resonance effect, the resonance sheet 3112 is bent away from the inlet plate 3111 correspondingly, which also increases the volume of the convergence chamber 3111c. Furthermore, since the gas inside the convergence chamber 3111c is drawn into the chamber space 3117, the convergence chamber 3111c is in a negative pressure state as well. Therefore, the gas can be drawn into the convergence chamber 3111c through the inlet hole 3111a and the convergence channel 3111b. Then, please refer to FIG. 6D. The piezoelectric element 3113d drives the suspension plate 3113a to move toward the inlet plate 3111, thereby compressing the chamber space 3117. Similarly, since the resonance sheet 3112 resonates with the suspension plate 3113a, the resonance sheet 3112 also moves toward the inlet plate 3111, thereby pushing the gas in the chamber space 3117 to be transmitted out of the chamber space 3117 through the at least one gap 3113e so as to achieve gas transmission. Last, please refer to FIG. 6E. When the suspension plate 3113a moves resiliently to its original position, the resonance sheet 3112 still moves away from the inlet plate 3111 due to its inertia momentum. At the time, the resonance sheet 3112 compresses the chamber space 3117, so that the gas in the chamber space 3117 is moved toward the at least one gap 3113e and the volume of the convergence chamber 3111c is increased. Accordingly, the gas can be drawn into the micro pump 311 continuously through the inlet holes 3111a and the convergence channels 3111b and can be converged at the convergence chamber 3111c. By continuously repeating the operation steps of the micro pump 311 shown in FIG. 6C to FIG. 6E, the micro pump 311 can make the gas continuously enter into the flow paths formed by the inlet plate 3111 and the resonance sheet 3112 from the inlet holes 3111a, thereby generating a pressure gradient. The gas is then transmitted outward through the at least one gap 3113e. As a result, the gas can flow at a relatively high speed, thereby achieving the effect of gas transmission.

Please refer back to FIG. 1, FIG. 2, and FIG. 4A to FIG. 4C. In this embodiment, when the gas bag layer 23 is under the inflation operation, the inlet on-off valve 35a is controlled by the control module 34 to open, by which the gas outside of the gas collection actuator 3 can enter into the gas collection actuator 3. Then, as shown in FIG. 4A, the micro pump 311 is driven by the control module 34 (shown in FIG. 1) to guide the gas to converge at the connection chamber 313d. The gas further passes through the connection holes 313e and enters into the second gas collection chamber 313a and the second gas relief chamber 313b. Accordingly, the valve membrane 314 is pushed and moved away from the chamber plate convex portion 313c, so that the gas may pass through the valve hole 314a of the valve membrane 314, enter into the first gas collection chamber 312b, and converge at the gas collection trough 312a through the gas collection through hole 312d. At the same time, as shown in FIG. 4B, the valve membrane 314 is pushed by the gas to abut against the gas collection valve base convex portion 312f, so that the gas relief through hole 312g is closed. In addition, the gas in the second gas relief chamber 313b enters into the second gas collection chamber 313a through the connection channel 312e. Then, the gas further passes through the valve hole 314a of the valve membrane 314, enters into the first gas collection chamber 312b, and converges at the gas collection trough 312a through the gas collection through hole 312d. Last, by converging the gas at the gas collection trough 312a, the gas bag layer 23 can be provided with the gas so as to complete the inflation operation and adjust the internal pressure of the gas bag layer 23. Afterwards, as shown in FIG. 4C, when the micro pump 311 stops guiding the gas, the internal gas pressure of the gas bag layer 23 is higher than the internal pressure of the connection chamber 313d. At the time, the gas in the gas bag layer 23 may push the valve membrane 314 to abut against the chamber plate convex portion 313c, thereby closing the valve hole 314a. Moreover, the valve membrane 314 is pushed and moved away from the gas collection valve base convex portion 312f thereby opening the gas relief through hole 312g. The outlet on-off valve 35b is controlled to open by the control module 34 at the time as well. Thus, the gas in the gas bag layer 23 is guided to the gas relief through hole 312g through the connection channel 312e and is discharged outside of the gas transmitter 3 to complete a gas-released operation.

In the pressure-adjustable brassiere pad 1 of this embodiment, by the continuous operation of the gas transmitter 31 to supply the gas to the gas passage 24 and then the gas being further guided into the gas bag layer 23, the gas bag layer 23 can be provided with the gas so as to be inflated. An amount of the gas in the gas bag layer 23 can be detected by the gas pressure detector 33, and by further cooperating with the control module 34, which controls the operation of the inlet on-off valve 35a and the operation of the outlet on-off valve 35b, the gas may be retained in the gas bag layer 23. In addition, by monitoring the internal pressure of the gas bag layer 23 through the gas pressure detector 33, the gas amount in the gas bag layer 23 can be adjusted in a proper range. For example, when the gas pressure detector 33 detects that the internal pressure of the gas bag layer 23 reaches an predetermined value, the micro pump 311 stops operating. If the inflation volume of the gas bag layer 23 is not enough to the user, the user may adjust the inflation volume of the gas bag layer 23 by setting up a new predetermined value through the control module 34. Accordingly, the softness, appearance, support strength, supporting performance, etc., of the main body 2 can meet the needs of users, and at the same time achieve the effect of intelligent power saving.

To sum up, one or some embodiments of the present disclosure provides a pressure-adjustable brassiere pad that the softness, appearance, support strength, supporting performance, etc., of the brassiere pad can be adjusted to meet the requirements of the user and the brassiere pad may achieve the effect of intelligent power saving as well. Therefore, the pressure-adjustable brassiere pad provided in one or some embodiments of the present disclosure can meet the different needs of each user. Thus, the industrial value of the present application is very high, so the application is submitted in accordance with the law.
