Abstract: The present disclosure provides a pushing force converting device including a cylinder barrel. The cylinder barrel includes an air cavity; a mounting cavity; and an air cavity vent in communication with the air cavity. The pushing force converting device also includes a piston configured to slide back and forth in the cylinder barrel and slidably disposed in the mounting cavity; a transmission bar connected with the piston and configured to drive the piston to move toward the air cavity; a restoring member disposed in the cylinder barrel and configured to drive the piston or the transmission bar to be restored to a respective initial position; and a sealing ring disposed on the piston and configured to seal the air cavity. The pushing force converting device disclosed by the present disclosure can convert mechanical pushing force into air pressure pushing force.

Abstract: A hidden water tank includes a water tank body, including a water inlet assembly and a pneumatic drainage assembly; and a driving panel detachably connected to the water tank body. The driving panel includes one of a pneumatic driving panel, a mechanical driving panel, or an electric driving panel. The mechanical driving panel and the pneumatic drainage assembly are connected through a first driving conversion module configured to convert a mechanical driving force generated by the mechanical driving panel into a first air pressure-driving force. The electric driving panel and the pneumatic drainage assembly are connected through a second driving conversion module configured to convert an electrical signal generated by the electric driving panel into a second air pressure-driving force.

Abstract: The present disclosure provides a split-type automatic lifting bracket device and a sanitary product. The split-type automatic lifting bracket device comprises an upper bracket assembly and a lower bracket assembly, wherein the upper bracket assembly is used for bearing a water receiver or a waterway control valve; and the lower bracket assembly is used for bearing or supporting and driving a sanitary product to rise and descend, and comprises a self-supporting leg assembly, an auxiliary standing device, an automatic lifting control device, a lifting bracket, a push-pull power device, a rolling guide device, and the sanitary product. The lifting structure of the present application can rise and descend automatically without an additional force to assist in height adjustment. The water receiver and other structures are not provided on the lifting bracket, so that a weight for the lifting structure to rise is reduced.

Abstract: The present application discloses a drain valve, comprising a valve body, a valve seat, and an overflow pipe. The valve seat includes a drainage channel. The overflow pipe includes a blocking element and a flow rate regulator. When the overflow pipe is in a raised state, the blocking element leaves a channel water inlet, the flow rate regulator is partially or completely located above the channel water inlet, and a water flow channel is formed between the flow rate regulator and the channel water inlet. An amount of water entering the drainage channel from the channel water inlet in unit time can be defined by the flow rate regulator, and thus a drainage flow rate can be controlled. If a user needs to change the drainage flow rate, the user only replaces different types of flow rate regulators, without replacing the whole drain valve to save costs.
