Description

Technical Field

[0001] The invention relates to a control switch, in particular to a button device. Background Art

[0002] With the improvement of living standards, intelligence has been increasingly integrated into life and has become the mainstream development trend of home furnishing. The drainage control of existing drain valves is mainly divided into two modes: manual control and induction control. The traditional pure mechanical manual control can no longer meet the needs of intelligent remote control functions. Existing smart toilets use induction control to control the drainage of drain valves, but usually use a motor-driven gear rack or a motor-driven cam to control the drain valve. If there is a power outage in the middle, the rack cannot be automatically reset, and the drain valve will continue to drain, causing a waste of water resources. At the same time, in the power outage state, the motor cannot work and the automatic drainage function cannot be realized.

[0003] Existing ordinary toilets are only equipped with traditional mechanical buttons, which can only control drainage manually. If they need to be upgraded to buttons with automatic drainage function, the traditional drain valve inside needs to be replaced, resulting in a waste of resources. Summary of the invention

[0004] The technical problem to be solved by the present invention is aimed at the above-mentioned shortcomings of the prior art. A button device is provided, which can control drainage manually and electrically, and is not afraid of power failure in the middle, and can automatically reset, so that the drainage valve will not be pressed all the time.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a button device, characterized by comprising: a shell body, a sliding cavity with an upper opening arranged in the middle, and a through hole arranged at the bottom of the sliding cavity;

[0006] A button frame, with a bottom hole arranged on the bottom surface, and slidably arranged in the sliding cavity to move up and down;

[0007] A motor, fixedly arranged on the button frame, with an output shaft extending downward through the bottom hole;

[0008] A screw rod is coaxially fixedly arranged with the output shaft of the motor;

[0009] A nut, matched with the screw thread;

[0010] A push rod, located below the button frame, movably disposed in the sliding cavity, with a lower end thereof extending downward through the through hole;

[0011] A damper is coaxially arranged with the screw and located between the nut and the push rod, and comprises a first rotating part and a second rotating part that have a mutual rotation damping effect, wherein the first rotating part is fixedly arranged with the nut, and the second rotating part is fixedly arranged with the push rod;

[0012] A reset spring is preloaded on the push rod and the housing body, and the direction of the preload force is the reset direction of the push rod.

[0013] The working principle of the present invention is: when the motor starts, the screw rotates, and the nut matched with the screw cannot rotate synchronously due to the rotational damping effect of the damper (because the motor rotates at a relatively fast speed, the damping slows down the rotation speed of the nut), so it moves downward under the thrust of the threaded match, and then pushes the push rod to move downward, and the reset spring is compressed; when the motor stops, the screw stops rotating, and the push rod moves upward under the elastic force of the reset spring, and the nut is forced to overcome the rotational damping of the damper and slowly rotates and moves upward until it is reset; when the power is off, the button frame is pressed, and then the push rod is pushed downward, so that the trigger operation of the lower mechanism can be realized.

[0014] The present invention is applied in the control of the drain valve, and can control the drain manually or electrically, and is not afraid of power failure in the middle of the process and can automatically reset.

[0015] Optionally, an adjusting rod is also included, and the adjusting rod is arranged on the push rod so as to be adjustable up and down.

[0016] Optionally, the push rod is coaxially provided with a countersunk hole section and a screw thread section from top to bottom, the countersunk hole section is fixedly matched with the second rotating part, and the screw thread section is threadedly matched with the adjusting rod.

[0017] Optionally, a radial convex rib is provided on the top surface of the first rotating part, an axial straight rib is provided on the annular wall of the second rotating part, a groove cooperating with the convex rib is provided on the bottom surface of the nut, and a straight groove cooperating with the straight rib is provided on the side wall of the countersunk section.

[0018] Optionally, a decorative cover is also included, and the decorative cover is fixedly arranged above the button frame.

[0019] Optionally, the button rack is a rotating body with an upper opening, a fixed compartment is arranged in the middle, and hooks and slots are arranged on the side walls. The motor is fixedly inserted in the fixed compartment, a buckle matching the slot is arranged below the side wall of the decorative cover, and a sliding groove matching the hook is arranged on the side wall of the shell body.

[0020] Optionally, a large nut is also included, a ring edge is arranged on the top surface of the outer ring wall of the shell body, and an outer screw thread matching with the large nut thread is arranged in the middle. Through the above arrangement, the button device can be conveniently clamped and fixed on the water tank cover.

[0021] Optionally, an orientation groove is provided on the bottom surface of the shell body, and an orientation rib matching with the orientation groove is provided on the side wall of the push rod.

[0022] Optionally, a circular ring is provided on the side wall of the top surface of the push rod, and one end of the return spring abuts against the lower end of the circular ring, and the other end abuts against the bottom surface of the sliding cavity.

[0023] Optionally, the nut is integrally provided on the first rotating part and or the screw is integrally provided on the output shaft.

[0024] The beneficial effects of the present invention are:

[0025] 1. The present invention can be controlled manually or electrically. It can flush automatically when there is electricity, and can flush manually when there is no electricity.

[0026] 2. The button in the present invention can automatically return to its original position when the power is off, and the drain valve will not be pressed all the time, causing waste of water resources.

[0027] 3. The present invention can directly replace the existing traditional mechanical buttons, upgrading the original manual control to a manual-automatic control function, without the need to replace other components, thus avoiding the waste of resources to the greatest extent.
