Description

Technical Field

[0001] The utility model relates to the field of toilet water valve buttons, in particular to a button for delaying water inlet. Background Art

[0002] The invention patent with publication number CN101736790A discloses a water inlet head, a water inlet body, and a bayonet. The water inlet head is provided with a water inlet inner pad, and below the water inlet inner pad is a core pulling head, the core pulling head has a water inlet channel, and the water inlet body is provided with an elastic sheet and a piston, the elastic sheet and the piston are sequentially mounted on the core pulling from top to bottom, the piston is fixed on the inner cavity of the water inlet body, the piston has a water hole and is communicated with the inner cavity of the water inlet body, a part of the elastic sheet covers the water hole of the piston and covers the water inlet channel of the core pulling head, the lower part of the core pulling is fixed in the bayonet, the inner cavity of the core pulling is communicated with the inner cavity of the bayonet, the lower part of the water inlet body is connected to the bayonet, the inner cavity of the water inlet body is communicated with the outer cavity of the bayonet, and the outer cavity outlet of the bayonet is communicated with the water tank.

[0003] Although the above patent can delay water inlet, the method of delaying water inlet is single and cannot adjust and control the water inlet time well. When the button cover is damaged, the water inlet cannot be delayed. When the button cover is quickly reset, the toilet cannot be effectively flushed, which wastes water resources and has a poor user experience. Utility Model Content

[0004] In order to solve the above problems, the present technical solution provides a button for delaying water inlet.

[0005] To achieve the above purpose, the technical solution is as follows:

[0006] A button for delayed water inlet, comprising a button cover, wherein the button cover is provided with a water inlet and a water outlet in sequence;

[0007] The button cover is also provided with a button, which is provided with a pressing part. A piston in contact with the pressing part is provided in the button cover, and a sealing part is provided in the piston. When the piston moves upward, the sealing part blocks the water outlet. When the piston moves downward, the water outlet discharges water normally. It also includes a suction cup located under the piston, and an air inlet is provided at the lower end of the suction cup. When the piston moves downward, it is sucked tightly by the suction cup. After the air inlet enters a certain air pressure, the piston can be separated from the suction cup and move upward.

[0008] In some embodiments, the pressing portion is sleeved with a first spring.

[0009] In some embodiments, a second spring is provided between the lower end of the piston and the inner wall of the button sleeve.

[0010] In some embodiments, the button is provided with a plurality of limiting portions passing through the button sleeve.

[0011] In some embodiments, the water cavity between the water inlet and the water outlet is provided with a plurality of detachably connected blocking parts.

[0012] The beneficial effects of this application are:

[0013] When the button is pressed, the pressing part drives the piston downward, so that the sealing part is separated from the water outlet to supply water. After the piston is sucked tightly by the suction cup, when the air pressure at the air inlet gathers to the same as the atmospheric pressure, the suction force of the suction cup is reduced, causing the piston to reset and block the water outlet, thereby achieving delay and ensuring the effect of delayed water inlet. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments.

[0016] Figure 2 It is a schematic diagram of the structure before pressing of an embodiment of the present utility model. DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] Please refer to Figure 1-2 As shown, a button for delayed water inlet includes a button cover 1, wherein the button cover 1 is provided with a water inlet 2 and a water outlet 3 in sequence;

[0019] The button cover 1 is also provided with a button 4, and the button 4 is provided with a pressing portion 5. A piston 6 in contact with the pressing portion 5 is provided in the button cover 1, and a sealing portion 7 is provided in the piston 6. When the piston 6 moves upward, the sealing portion 7 blocks the water outlet 3. When the piston 6 moves downward, the water outlet 3 discharges water normally. The button cover 1 also includes a suction cup 8 under the piston 6. An air inlet 9 is provided at the lower end of the suction cup 8. When the piston 6 moves downward, it is sucked tightly by the suction cup 8. After the air inlet 9 enters a certain air pressure, the piston 6 can be separated from the suction cup 8 and move upward.

[0020] When the button is pressed, the pressing part drives the piston downward, so that the sealing part is separated from the water outlet to supply water. After the piston is sucked tightly by the suction cup, when the air pressure at the air inlet gathers to the same as the atmospheric pressure, the suction force of the suction cup is reduced, causing the piston to reset and block the water outlet, thereby achieving delay and ensuring the effect of delayed water inlet.

[0021] In this embodiment, the pressing portion 5 is sleeved with a first spring 10 so that the button has a reset function.

[0022] In this embodiment, a second spring 11 is provided between the lower end of the piston 6 and the inner wall of the button sleeve 1 , and the force generated by the spring enables the sealing portion to tightly seal the water outlet.

[0023] In this embodiment, the button 4 is provided with a plurality of limiting portions 12 passing through the button cover 1 .

[0024] In this embodiment, the water cavity between the water inlet 2 and the water outlet 3 is provided with a plurality of detachably connected blocking portions 13 .

[0025] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other embodiments whose principles and basic structures are the same or similar to those of the present application are within the scope of protection of the present application.
