Description

Technical Field

[0001] This utility model relates to the field of control valve technology, and in particular to a hydraulic foot pedal control switch. Background Technology

[0002] Foot-operated flush valves are frequently used in restrooms to control the flushing of squat toilets, especially in public restrooms where concealed foot-operated flush valves are often used.

[0003] Existing foot-operated flush valves are generally installed on water pipes near squat toilets, requiring sufficient space around them for installation and foot operation. Because existing foot-operated flush valves include a valve body and a spring-loaded, time-delayed return check valve, the spring-loaded return mechanism is relatively complex. Furthermore, the valve body has front and rear interfaces for connecting to the water pipe, resulting in a large size that makes installation and use difficult in some situations, and is not suitable for installation or use in confined spaces. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a hydraulic foot pedal control switch that is easy to install separately from the flushing valve body, occupies little space, and is easy to install and use flexibly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A hydraulic foot pedal control switch includes a mounting base, a control valve, and quick connectors. The mounting base has a protruding valve seat with a valve mounting cavity. The bottom of the valve mounting cavity has a countersunk hole with a first connecting hole connected to a first interface. The bottom surface of the valve mounting cavity has a second connecting hole connected to a second interface. The control valve is located in the valve mounting cavity and is used to control the on / off connection between the first and second connecting holes. The quick connectors are located in the first and second interfaces. One quick connector is connected to a fluid input pipe, and the other quick connector is connected to a fluid control pipe. The fluid control pipe is used to switch the valve on and off.

[0006] Furthermore, the control valve is a foot-operated one-way control valve.

[0007] Furthermore, the inlet section of the valve mounting cavity is provided with an internal thread for mounting the control valve.

[0008] Furthermore, the mounting base is provided with mounting holes.

[0009] Furthermore, the first interface and the second interface are located on the same side of the mounting base.

[0010] Furthermore, the fluid input pipe or fluid control pipe is a flexible hose.

[0011] This utility model has the following beneficial effects: 1. This utility model provides a mounting base that is easy to install separately from the main body of the flushing valve. The mounting base is equipped with an independent control valve and two quick connectors. The quick connectors are connected to the flushing valve through a fluid control pipe. The flushing valve can be controlled by the separate installation and control valve. The mounting base occupies little space and is easy to install and use flexibly.

[0012] 2. The valve mounting structure and the internal first connecting hole, first interface, second connecting hole and second interface connection structure of the mounting base of this utility model are ingeniously designed and the overall structure is reliable. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See Figure 1-4As shown, a hydraulic foot pedal control switch includes a mounting base 1, a control valve 2, and a quick connector 3. The mounting base 1 has a protruding valve seat 11, and the valve seat 11 has a valve mounting cavity 12. The inlet section of the valve mounting cavity 12 has an internal thread for mounting the control valve 2. The bottom of the valve mounting cavity 12 has a countersunk hole 13, and the countersunk hole 13 has a first connecting hole 14 connected to a first interface 15. The bottom surface of the valve mounting cavity 12 has a second connecting hole 16 connected to a second interface 17. The control valve 2 is disposed in the valve mounting cavity 12 and is used to control the on / off connection between the first connecting hole 14 and the second connecting hole 16. The control valve 2 is a through / through... The foot-operated one-way control valve closes when the foot is removed, the first connection hole 14 and the second connection hole 16 are no longer connected, and no water flows out. This is more water-saving than the delayed reset spring structure. The first interface 15 and the second interface 17 are equipped with quick connectors 3. One quick connector 3 is connected to the fluid input pipe, and the other quick connector 3 is connected to the fluid control pipe. The fluid control pipe is used to switch the flush valve 4 on and off. The flush valve 4 is an existing product. The input end of the flush valve 4 is connected to tap water, and the output end is connected to the squat toilet. The fluid input pipe or the fluid control pipe is a flexible hose for easy installation and operation. In this way, the flush valve 4 can be installed separately and flexibly in a place that does not occupy operating space.

[0019] The mounting base 1 is provided with mounting holes 18, which facilitates concealed installation of the mounting base 1. The first interface 15 and the second interface 17 are located on the same side of the mounting base 1, which facilitates quick connection and installation of the connecting pipe.

[0020] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
