Description

Technical Field

[0001] The utility model specifically relates to a foot-operated flush valve for a toilet, belonging to the technical field of foot-operated flush valves. Background Art

[0002] At present, many people are reluctant to touch the flush valve with their hands in public toilets, so foot-operated flush valves came into being. The foot-operated control valve does not require hand contact with any part of the flush valve, which can effectively avoid cross-infection of bacteria. The foot-operated control valve can be stepped on normally for more than 200,000 times, is durable and has a long service life. It uses a hydraulic foot control switch and does not require power supply, so it is energy-saving, environmentally friendly and safe. The equipment has a simple structure and is easy to disassemble and assemble, and can be disassembled, cleaned and maintained by yourself without affecting the design environment.

[0003] For example, the announcement number CN207729027U discloses a foot-operated flush valve comprising a three-way main body, wherein the upper end of the three-way main body serves as a water inlet, the lower end serves as a water outlet, and the side end serves as a mounting port for a foot pedal assembly. A valve core housing and a ball valve are mounted in the water inlet. The valve core housing comprises an upper cavity and a lower cavity, wherein one side of the upper cavity is provided with a water inlet, and the sidewall of the lower cavity is provided with an exhaust groove. The ball valve is inserted into the lower cavity of the valve core housing, and a first spring is provided between the ball valve and the top of the lower cavity of the valve core housing. The top of the valve core housing is connected to a water inlet connector via a first fixing nut via a thread, and a first gasket is provided between the water inlet connector and the valve core housing. A second gasket is fixed to the lower portion of the ball valve via a water outlet notch, and the second gasket is located in the through hole between the upper and lower cavities of the valve core housing. The water outlet is threadedly connected to a second nut. This utility model can automatically remove blockages such as scale through the drain groove, preventing the ball valve from clogging and affecting normal use of the product.

[0004] The common foot-operated flush valve used in the bathroom is used to flush the water without touching the flush valve with hands. However, the pedal collides with the ground after long-term use and lacks a buffer device, making it prone to damage. In addition, when stepping on the pedal, it is easy to slip and cause the foot to fall off, posing certain safety hazards. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies of the prior art and provide a foot-operated flush valve for a toilet, so as to avoid damage to the pedal and prevent the foot from sliding off the pedal during use.

[0007] Furthermore, in order to enable the limit plates to move simultaneously, the driving assembly includes a bidirectional screw, a sliding groove is provided in the middle position of the upper end of the pedal, a sliding block is symmetrically clamped inside the sliding groove, the sliding block is fixedly connected to the limit plate, the sliding block is threadedly connected to the bidirectional screw, the sliding block can move in the sliding groove, and the bidirectional screw is used to move the sliding block.

[0008] Furthermore, in order to facilitate the rotation of the bidirectional screw, a handwheel is fixedly mounted on one end of the bidirectional screw.

[0009] Furthermore, in order to enable the sliding block to move smoothly, the buffer assembly includes a guide rod and a buffer plate with a buffer pad installed at one end. The upper end of the support plate is symmetrically provided with a square groove. The guide rod is fixedly installed in the square groove. A square block is clamped in the square groove. The square block is sleeved on the outside of the guide rod. The buffer pad is used to preliminarily buffer the impact force brought by the pedal. The square block can move in the square groove.

[0010] Furthermore, in order to buffer the impact force brought by the pedal, a connecting plate is hinged at one end of the square block, and one end of the connecting plate is hinged to the buffer plate. A first spring is sleeved on the outside of the guide rod, and one end of the first spring is fixedly installed in the square groove, and the other end of the first spring is fixedly connected to the square block. The deformation force generated by the first spring is used to buffer the impact force brought by the pedal.

[0011] Furthermore, in order to ensure the smooth movement of the buffer plate, a round rod is inserted into one end of the support plate, and one end of the round rod is fixedly connected to the buffer plate.

[0012] Furthermore, in order to enable the arc rod to move, an arc tube is fixedly installed on the upper end of the support plate, an arc rod is slidably installed inside the arc tube, and one end of the arc rod is fixedly connected to the buffer plate.

[0013] Furthermore, in order to ensure the smooth reset of the pedal, an arc spring is sleeved on the outside of the arc rod, one end of the arc spring is fixedly connected to the buffer plate, and the other end of the arc spring is fixedly connected to the arc tube. The deformation force generated by the arc spring is used to move the pedal.

[0014] The technical effects and advantages of the utility model: When in use, the utility model drives the limit plate to move by rotating the bidirectional screw, and adjusts the distance between the limit plates, thereby limiting the feet of users of different age groups to prevent the feet from sliding during use. The buffer plate can also buffer the impact force brought by the pedal, avoiding damage to the pedal after a long period of collision with the ground, thereby increasing its service life.
