Description
FIELD OF THE INVENTION

The present invention relates to a toilet seat with an automatic turning cover, in particular to an electric toilet seat that can be lifted and controlled electrically, and whose surface can be turned towards the front while the toilet seat is being lifted.

BACKGROUND OF THE INVENTION

A conventional manual lifting toilet seat coupled to a toilet stool includes a toilet seat cover and a toilet seat. The toilet seat cover and the toilet seat are regularly covered onto the toilet stool, and the toilet seat is lifted up manually by hands when the toilet stool is used. Particularly for male urinations, the toilet seat cover is also lifted up to avoid spilling urine on the surface of the toilet seat cover. However, for convenience, male users generally do not lift up the toilet seat cover, and urine may be accumulated at the toilet seat cover and an internal side of the lifted toilet seat. Even if the toilet seat cover is lifted, urine may be spilled from a hollow portion of the toilet seat cover into the internal side of the toilet seat. If the next user needs to sit on the toilet seat cover, the rear side of the cloth of this user may touch the internal side of the toilet seat easily, which is really disgusting. Although toilet seats with an electrically lifted cover are available in the market, yet the toilet seats of this sort can lift the toilet seat only, and the internal side of the toilet seat is still facing towards the front. Therefore, it is unable to overcome the drawback of the cloth being in contact with the internal side of the toilet seat having accumulated urine when a user is sitting on a toilet seat cover. The sanitary problem still exists.

It is an important subject of the present invention to find a way of developing a toilet seat with an automatic turning cover, such that users no longer have to lift a toilet seat and a toilet seat cover by hands, and when the toilet seat is lifted, the surface of the toilet seat will change its direction towards the front to avoid the users' cloth from touching the internal side of the toilet seat.

SUMMARY OF THE INVENTION

In view of the aforementioned shortcomings of the conventional manual and electric toilet seat, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a toilet seat with an automatic turning cover in hope of achieving the sanitary effect.

Therefore, it is a primary objective of the present invention to provide a toilet seat with an automatic turning cover, such that the surface of the toilet seat is changed to face towards the front by means of a design of an electric toilet seat and a turning structure when the toilet seat is lifted by an electric control, so as to achieve the effects of providing a sanitary appearance, preventing the users' cloth from touching the internal side of the toilet seat, providing an easy way of using a toilet stool and keeping the toilet stool clean and sanitary.

To achieve the foregoing objective, the present invention provides a toilet seat with an automatic turning cover, comprising: a start device, having a first rotating portion and a second rotating portion disposed on a base respectively, and a motor for driving and rotating the first rotating portion and the second rotating portion; a toilet seat cover, with a rear end coupled with the second rotating portion of the start device; a toilet seat, having a pivotal base disposed at an internal side of the toilet seat, and the pivotal base having an upper pivoting portion and a belt fixing portion; an elevating arm, with a rear end coupled with the first rotating portion of the start device, and a lower pivoting portion disposed at the middle of the elevating arm; a turning arm, having a long rod with a groove disposed at the middle of the long rod, and a lower end of the long rod being rotably coupled to the lower pivoting portion of the elevating arm, and an upper end of the long rod being rotably coupled to an upper pivoting portion of the pivotal base on an internal side of the toilet seat, an elastic element coupled with the upper end for pushing the toilet seat, an upper axle installed transversally in the groove and proximate to the upper end, and a lower axle is installed transversally and proximate to the lower end; and a belt, with a lower end fixed at the bottom of the toilet seat cover, an upper end passed from the bottom of the lower axle of the turning arm into the groove, through the lower axle and the upper axle, and then from the top of the upper axle and out of the groove, such that the upper end is coupled to the belt fixing portion of the pivotal base on an internal side of the toilet seat to constitute the toilet seat with an automatic turning cover.

The aforementioned design of a toilet seat with an automatic turning cover has at least three modes of lifting a toilet seat. Firstly, a user can use the start device to drive the elevating arm and the turning arm to lift the toilet seat independently through an operation of a control box while the belt is pulled to change the direction of the surface of the toilet seat to face towards the front, so as to achieve the effect of keeping the toilet stool sanitary easily. Secondly, the start device can be controlled and driven to lift the toilet seat cover and the toilet seat synchronously when male users urinate, so as to prevent urine from being spilled onto the toilet seat cover and maintain a clean and sanitary toilet stool. Thirdly, the toilet seat or the toilet seat cover can be lifted manually during a power failure.

The belt 6 as shown in FIGS. 1 to 3 is a flexible strip, whose lower end is passed through the elevating arm 4 and the toilet seat cover 2 and fixed to the bottom of the toilet seat cover 2 (as shown in FIGS. 2 and 4), and whose upper end is passed from the bottom of the lower axle 54 of the turning arm 5 into the groove 51, and through the lower axle 54 and the upper axle 53, and then through the top of the upper axle 53 and out from the groove 51, such that the upper end of the belt 6 is coupled to the belt fixing portion 33 of the pivotal base 31 at the internal side of the toilet seat 3.

In FIGS. 1 to 3, the pivotal base 31 of the toilet seat 3 in accordance with the preferred embodiment includes coupled to the two protruding bases 311 on the internal side of the toilet seat 3, and the upper pivoting portion 32 and the belt fixing portion 33 are disposed transversally at transversal rods between the two protruding bases 311 respectively, and one of the transversal rods is passed through an upper end of the turning arm 5, and another transversal rod is coupled to an upper end of the belt 6, and the upper end of the belt 6 is coupled to a latch ring 61, and the latch ring 61 can be an elliptical ring for latching to the belt fixing portion 33 in the shape of the transversal rod.

With the design of a toilet seat with an automatic turning cover of the present invention as shown in FIG. 5, the toilet seat cover 2 and the toilet seat 3 are maintained covered regularly, such that if a user needs to use the toilet stool, the user can lift the toilet seat electrically by operating a control box or a sensor or by hands.

In the first type of the electric operating mode, a user performs the lifting operation through the control box or sensor as shown in FIGS. 2 and 6, so that the first rotating portion 12 of the start device 1 is rotated, while the elevating arm 4 is being driven to turn backward, and the elevating arm 4 is supporting the turning arm 5 synchronously, and the toilet seat 3 pivotally coupled to the upper end of the turning arm 5 can be lifted independently. In the meantime, the lower axle 54 of the turning arm 5 is turned backward, and thus the lower axle 54 pulls the belt 6 gradually tighter, and the upper end elliptical latch ring 61 is latched to the belt fixing portion 33 gradually tighter. Until the toilet seat 3 is lifted to a specific height and a sufficient turning space is reserved at the front end, the belt 6 and the latch ring 61 can drag the belt fixing portion 33 downward until the toilet seat 3 is turned downward. In FIGS. 7 and 8, if the elevating arm 4 and the turning arm 5 rise to fixed positions, the belt 6 will pull the toilet seat 3 tightly, so that the surface of the toilet seat 3 will turn and change its direction towards the front of the toilet seat cover 2 to show the clean appearance of the toilet seat, and prevent a user's cloth from touching the internal side of toilet seat 3 to achieve a sanitary effect easily when the user uses the toilet stool. On the other hand, if the user controls the toilet seat 3 to move downward to cover toilet seat cover 2 as shown in FIGS. 1 and 5, the first rotating portion 12 of the start device 1 will drive the elevating arm 4 and the turning arm 5 to turn forward, while the lower axle 54 of the turning arm 5 is turned forward to release the belt 6, such that the upper end of the belt 6 is released from tightly pulling the toilet seat 3, and then the elastic element 52 at the upper end of the turning arm 5 props the toilet seat 3, so that the toilet seat 3 changes the direction to be covered onto toilet seat cover 2.

In a second electric operating mode of the present invention, the user performs the lifting operation through the control box or sensor as shown in FIGS. 9 and 10, so that the first rotating portion 12 and the second rotating portion 13 of the start device 1 synchronously drive the elevating arm 4 and the toilet seat cover 2, wherein the elevating arm 4 can also lift turning arm 5, such that the toilet seat 3 coupled to the upper end of the turning arm 5 can be lifted. However, the toilet seat cover 2 is also lifted upward synchronously, so that a fixing point of the lower end of the belt 6 being fixed to the bottom of the toilet seat cover 2 rises synchronously, and the lower axle 54 of the turning arm 5 cannot pull the belt 6 tightly, and the toilet seat 3 will not change its direction. The toilet seat 3 and the toilet seat cover 2 stacked with one another are lifted together, so that a male user needs not to lift the toilet seat 3 and the toilet seat cover 2 before taking a urination, and the toilet seat cover 2 can be kept clean easily. On the other hand, both toilet seat 3 and toilet seat cover 2 can be turned downward simultaneously and covered onto the toilet stool again.

In a third mode which is the manual operation of the present invention as shown in FIG. 1, the user can lift the toilet seat 3 manually by hands during a power failure.
