Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a multifunctional knob switching valve. Background Art

[0002] Many valves use a knob-type switching structure, which drives the valve core to switch the waterway and water flow by rotating the knob. The existing knob-type switching structure generally only has a switching function and no longer has other functions, resulting in a single function of the knob. It is difficult to further simplify the mechanism of the valve using it. For example, some valves need to have a detection function, such as the common detection of the fluid pressure inside the valve body, which requires opening a hole in the valve or the pipe connecting the valve and inserting a detector. If the detection information needs to be displayed, an exposed display screen needs to be set outside the valve or pipe, resulting in a complex structure of the valve or pipe, and poor external aesthetics, which is not popular with consumers. For this reason, the utility model provides a multifunctional knob switching valve, which can solve the above technical problems and has high market competitiveness. Utility Model Content

[0047] The valve core 2 and the knob assembly 3 are connected and rotate synchronously through the plug-in concave-convex structure. For example, in this embodiment, the concave-convex structure includes a plug-in groove 22 arranged at one end of the valve core 2 facing the knob assembly 3, and also includes a plug connector 321 arranged at the end of the knob assembly 3.

[0048] The knob assembly 3 includes a detection member 311, which is connected to the fluid channel 11 of the valve through the detection hole 21, so as to detect the fluid flowing through the valve body 1 and determine the state of the fluid. To simplify the structure, in one embodiment, the detection hole 21 is arranged in the plug slot 22, and a connecting hole 322 is arranged inside the plug connector 321, and the detection member 311 is connected to the fluid channel 11 of the valve through the connecting hole 322 and the detection hole 21.

[0049] As for the specific scheme of the knob assembly 3, in one embodiment, the knob assembly 3 includes a knob body 31 and a rotating seat 32.

One end of the knob body 31 is inserted into the plug-in port 323 of the rotating seat 32, and the other end extends out of the installation cavity 12. The knob body 31 and the rotating seat 32 are relatively fixedly installed, and the detection member 311 is arranged on the knob body 31, and the fluid channel 11 of the valve is connected through the plug-in port 323, the connecting hole 322 and the detection hole 21. Preferably, in order to improve the sealing performance and avoid leakage, a sealing ring is provided between the periphery of the rotating seat 32 and the inner wall of the installation cavity 12, and a sealing ring is also provided between the periphery of the knob body 31 and the inner wall of the plug-in port 323.

In addition, the fluid channel 11 includes an inlet channel and an outlet channel, and the detection member 311 is always connected to the inlet channel or the outlet channel through the valve core 2.

[0057] The knob switching structure provided by the utility model, on the basis of the original rotation switching function, further provides a detection member 311 on the knob assembly 3, and opens a detection hole 21 on the valve core 2 for the detection member 311 to connect to the fluid channel 11, so that the knob assembly 3 also has the function of detecting the state of the fluid flowing through the valve body 1. On the one hand, it enriches the function of the knob assembly 3, and on the other hand, it replaces the traditional structure of additional holes and exposed detectors on the valve body 1 or the pipeline, which not only reduces the space required for the installation of the valve body 1 and reduces the difficulty of installation, but also avoids the appearance of a monotonous industrial design, which is more popular with consumers and has higher market competitiveness.
