Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a light-press water channel control structure. Background Art

[0002] There are various water channel switching structures, a common example being a button switching structure. Currently, most button switching structures on the market use a ballpoint pen switching structure. This type of switching structure or other types of button switching structures require a large force to overcome elastic force, friction force or water force, etc., which gives the user a bad experience. At the same time, the switching structure is prone to damage under the action of long-term switching force. For this reason, the utility model provides a water channel switching structure that only needs to be pressed lightly when used, which can solve the above technical problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a water channel switching structure that is easy to operate.

[0004] A light-touch waterway control structure includes a switching body, a pilot valve and a swing switch, wherein:

[0005] The switching body includes a water inlet channel, an installation cavity and a water outlet channel, and the installation cavity includes a first installation cavity and a second installation cavity, and the water outlet channel includes a first water outlet channel and a second water outlet channel. Specifically, the water inlet channel is connected to the first water outlet channel through the first installation cavity, and the water inlet channel is connected to the second water outlet channel through the second installation cavity.

[0006] The pilot valve includes a first pilot valve and a second pilot valve, and the first pilot valve and the second pilot valve are respectively installed in the first installation cavity and the second installation cavity, so as to respectively control the on-off state of the two water channels.

[0007] The rocker switch is mounted on the outer periphery of the switch body in a swinging manner using a lever, with its ends connected to the valve stems of the two pilot valves. In the water flow state, the rocker switch switches the two pilot valves, creating the effect of inserting one valve stem and withdrawing the other, allowing water to flow out of either the first or second water outlet channel.

[0008] The water circuit control structure provided by the present invention uses a pilot valve as the valve core, and utilizes the advantage of the pilot valve being light when switching the water circuit state, thereby providing the user with a light switching operation experience. In addition, by setting the swing switch, the two pilot valves can be linked together to form an open and closed state, thereby forming a light water circuit control structure based on the pilot valve.

[0009] Preferably, one end of the installation cavity is provided with a water passage and a drainage passage that are arranged inside and outside and are connected, and the other end is provided with a pressure relief cavity, and the water passage and the water inlet channel are connected. The pilot valve includes an elastic sealing piece. The periphery of the elastic sealing piece is fixedly installed in the installation cavity and divides the pressure relief cavity and the water passage, while the middle part blocks the water inlet of the drainage channel under the action of its own elastic force. The elastic sealing piece is provided with an overflow hole and a pressure relief hole, the overflow hole connects the pressure relief cavity and the water passage, and the pressure relief hole connects the pressure relief cavity and the drainage channel. The valve stem extends from the outside and enters the drainage channel through the pressure relief hole. The diameter of the valve stem is equal to the pressure relief hole, and a contraction section is provided at the end. When the valve stem is pressed down, the contraction section completely enters the pressure relief hole, and the pressure relief hole is in a blocked state. Alternatively, when the valve stem is pulled up, the contraction section partially exits the pressure relief hole, and the pressure relief hole is in an open state.

[0010] Preferably, the pressure relief hole is staggered from the center of the elastic sealing piece to form an eccentric hole, which can avoid resonance during drainage.

[0011] Preferably, in order to improve the sealing effect of the elastic sealing piece when the water is cut off, the pilot valve also includes a reset spring, and the reset spring compression sleeve is arranged on the valve stem, with one end pressing against the elastic sealing piece and the other end pressing against the end of the installation cavity.

[0012] Preferably, the two mounting cavities are distributed in sequence along the axial direction of the switching body, which can avoid increasing the diameter of the switching body.

[0013] Preferably, the two water outlet channels are arranged in parallel at the bottom of the two installation cavities, with a compact layout.

[0014] Preferably, two water outlet grooves are formed at the bottom of the switching body and are covered by a cover plate to form the two water outlet channels, so that the switching body can be formed by split parts, reducing the difficulty of forming.

[0015] Preferably, the cover plate and the switching body are fixed by welding, which makes the installation simple and firm.

[0016] Preferably, the outer periphery of the water inlet end of the water inlet channel is provided with a docking thread to facilitate docking with the water inlet pipe.

[0017] Preferably, the device further comprises a housing, which is sleeved around the outer periphery of the switch body and has an opening reserved for the rocker switch to be exposed. The housing has a constriction at one end for the water inlet, and the switch body is inserted from the other end of the housing. The water inlet end of the switch body extends from the constriction of the housing. A retaining ring with internal threads is screwed into the water inlet end of the switch body to secure the housing and the switch body.

[0018] From the above description of the present invention, it can be seen that the present invention has the following beneficial effects:

[0019] The waterway control structure provided by the utility model uses a pilot valve as a valve core, and takes advantage of the pilot valve's lightness when switching the waterway state, which can provide users with a light switching operation experience. In addition, by providing the swing switch, the two pilot valves can be linked together to form an open and closed state, thereby forming a light waterway control structure based on the pilot valve;

[0020] The pressure relief hole is an eccentric hole, which can avoid resonance during drainage;

[0021] By providing a return spring, the sealing effect of the elastic sealing piece can be improved when the water supply is cut off;

[0022] The two installation cavities are sequentially distributed along the axial direction of the switching body, which can avoid the diameter of the switching body from being enlarged, and the two water outlet channels are arranged in parallel at the bottom of the two installation cavities, which has a compact layout;

[0023] The switching body is formed by splitting parts, which reduces the difficulty of forming. BRIEF DESCRIPTION OF THE DRAWINGS
