Abstract: Disclosed are a single-material all-plastic pump and a storage bottle applied thereby, mainly including a plastic pressing head, a plastic pump casing, a plastic piston mechanism and a plastic reset spring; the plastic pressing head is in a pressable connection with the plastic pump casing, and has a discharge hole which is connected and communicated with a discharge end of the plastic piston mechanism; the plastic piston mechanism is disposed inside the plastic pressing head and the plastic pump casing, has a feed end which is connected and communicated with a material guide hose, and is used to control the opening and closing of the discharge hole and the material guide hose; the plastic reset spring is sleeved outside the plastic piston mechanism and compressed between the plastic pressing head and the plastic pump casing; and therefore, materials used in the solution are generally plastic, soft rubber, etc.

Abstract: A housing of a centrifugal fan, a centrifugal fan and a clothes dryer; a layered structure is provided within an air duct of the housing, and the layered structure is configured to be able to divide at least a part of the air duct into at least two air layers, the width of an air layer close to a strong air end being greater than the width of an air layer close to a weak air end. Also disclosed are a centrifugal fan having the housing and a clothes dryer having the centrifugal fan. By the layered structure being disposed within the air duct, the air duct is divided into at least two air layers, and the width of the wind layer close to the strong wind end is greater than the width of the wind layer close to the weak wind end.

Abstract: The disclosure provides an anti-pollution bottle cap comprising a cap body, a liquid drainage one-way valve and an air intake one-way valve. A liquid drainage hole and an air intake hole are disposed in the cap body and both communicated with an inside of the cap body. The liquid drainage one-way valve is disposed in a space enclosed by the cap body. The liquid drainage hole is blocked by the liquid drainage one-way valve in one way so as to be opened during toppling operation. The air intake one-way valve is disposed in the space enclosed by the cap body. The air intake hole is blocked by the air intake one-way valve in one way so as to be closed during toppling operation. In application, the anti-pollution bottle cap will be installed on a bottle for matched use, so that a user can normally drain liquid through the liquid drainage hole only by squeezing the bottle.

Abstract: The present disclosure provides a method and apparatus for skill sharing. A user's first click operation on a sharing link of a first skill is received; and the page jumps to a skill development page according to the first click operation, where the skill development page includes an input box of a link and an import button, and the input box is used to input a sharing link of a skill, while the import button is used to input an import instruction of the skill; and the first skill is imported into a skill development platform according to a user operation. By generating a sharing link of the skill, the sharing link of the skill can be shared within any location in existing sharing ways. The sharing manner thus enables the user to import the first skill in a variety of ways and avoids repeated development from different developers.

Abstract: A circuit includes a first operating component, a second operating component and a starting time control circuit. The starting voltage of the first operating component is different from that of the second operating component, and the starting time control circuit is configured to regulate a starting time of the first operating component to be synchronous with that of the second operating component.

Abstract: Machine logic implemented techniques for preventing sending messages by mistake (with such “mistakes” including sending a message to an unintended recipient). One embodiment of the technique includes: detecting an intention of sending a message to a target user; responsive to detection of the intention, predicting a risk that the target user is not a desired recipient of the message; and providing a prompt responsive to the predicted risk being higher than a predetermined threshold.

Abstract: A hair dryer includes a housing, and a heating unit, an air supply unit and a circuit board which are arranged inside the housing. The air supply unit includes an impeller and a single-phase direct current brushless motor for driving the impeller. The single-phase direct current brushless motor includes a stator and a rotor which is rotatable relative to the stator. The stator includes a stator core and a single-phase winding wound on the stator core. The rotor includes a shaft and a permanent magnet fixed on the shaft. A power supply terminal for connecting an external power supply and an inverter for providing an alternating current to the single-phase winding are arranged on the circuit board. An input voltage of the inverter is no lower than an input voltage of the power supply terminal.

Abstract: Embodiments of a golf club head and methods to manufacture such a golf club head are generally described herein. The golf club head generally includes at least one ball-striking face, which comprises a titanium alloy that is associated with an average grain size measuring no more than about 1 micron (?m) in the longest dimension. The golf club head is associated with a coefficient of restitution of about 0.847 or more when a ball impacts the ball-striking face.
