[0029] Now combined Figures 1 to 6 The structure and function of the solution of this application are described in detail.

[0030] refer to Figure 1 and Figure 6 The present invention provides a push switch module 1, which is used to be connected to a faucet body 7 of a faucet to switch the water flow of the faucet. Figure 2 The push switch module 1 includes a valve seat 2, a switch valve 3 and a button 6. The switch valve 3 is installed on the valve seat 2. The switch valve 3 has a water outlet at one end in the axial direction and a water inlet in the circumferential direction. The button 6 is connected to the end of the switch valve 3 away from the faucet body 7. By applying pressure to the switch valve 3, the water inlet and the water outlet are switched between the connected and disconnected states. The switch module also includes a flow regulating member 4. The flow regulating member 4 is sleeved between the faucet body 7 and the valve seat 2, and is configured to be sleeved on the outer periphery of the faucet body 7 in a rotatable manner relative to the valve seat 2. The valve seat 2 has a water passage 21 connected to the water inlet. The flow regulating member 4 is provided with a regulating port 41 connected to the water inlet. The regulating port 41 regulates the cross-sectional area S of the water inlet connected to the faucet body 7 to change within a preset threshold when the flow regulating member 4 is operatively rotated relative to the valve seat 2.

[0031] In a preferred embodiment, in combination Figure 3 , Figure 4 and Figure 5 When the flow regulating member 4 is operatively rotated relative to the valve seat 2, the regulating port 41 changes from partially overlapping to completely offsetting with the water inlet. That is, the cross-sectional area S of the water inlet connected to the faucet body 7 changes between the preset minimum flow rate and the maximum flow rate of the water inlet.

[0032] In another embodiment, in combination Figure 3 , Figure 4 and Figure 5, the regulating port 41 changes from completely overlapping to completely offset or partially offset with the water inlet when the flow regulating member 4 is operatively rotated relative to the valve seat 2. That is, the cross-sectional area S of the water inlet connected to the faucet body 7 is changed so that the water flow rate is between 0 and the maximum flow rate of the water inlet, or the cross-sectional area S of the water inlet connected to the faucet body 7 is changed between 0 and the preset maximum flow rate. In a preferred embodiment, the above-mentioned water inlet and regulating port 41 are longer in the circumferential direction, and are configured as a runway-type structure. This structure allows the user to adjust the water output appropriately by rotating, and will not adjust it too much at once. In other embodiments, it can be configured as a circular, directional or axially longer structure.

[0033] Combination Figure 3 , the flow regulating member 4 and the valve seat 2 are provided with a first limiting member 22 on one side and a second limiting member 42 on the other side, and the first limiting member 22 can abut against the second limiting member 42 during the rotation of the flow regulating member 4 so that the cross-sectional area S of the water inlet connected to the faucet body 7 changes within a preset threshold. The first limiting member 22 is constituted as one or two protrusions on the peripheral wall, and an activity space is formed at the end of the protrusion. The second limiting member 42 moves in the circumferential direction in the activity space so that the cross-sectional area S of the water inlet connected to the faucet body 7 changes within a preset threshold.

[0034] refer to Figure 3 An annular water groove 43 connected to the regulating port 41 is provided on the outer periphery of the flow regulating member 4, and water from the faucet body 7 can flow into the regulating port 41 through the annular water groove 43. The annular water groove 43 can facilitate the flow regulating member 4 to be installed into the faucet body 7 without adjusting it to a specific angle.

[0035] Combination Figure 2 and Figure 6 The end of the valve seat 2 away from the button 6 is provided with an external thread connection part, and the push switch module 1 is locked on the faucet body 7 through the external thread connection part. The valve seat 2 includes a seat body and a valve core stopper, the seat body has an external thread connection part, and an internal thread connection part is provided on the other end of the seat body for fixing and installing the valve core stopper, and the valve core stopper can be installed after the switch valve 3 is installed in the valve seat 2, and is used to cooperate with the seat body to limit the switch valve 3 along the axial direction.

[0036] Combination Figure 6The flow regulating member 4 has sealing parts arranged on both sides of the annular water groove 43, which are used to separate the annular water groove 43 and the water outlet. The end of the flow regulating member 4 close to the button 6 is provided with a first connecting member for connecting a force applying member 5, and the force applying member 5 can be operated to drive the flow regulating member 4 to rotate through the first connecting member to adjust the cross-sectional area S of the water inlet connected to the faucet body 7. The first connecting member is composed of a plurality of leaf springs arranged along the circumference or a single leaf spring with a hook, and the force applying member 5 is provided with a second connecting member adapted to the hook.

[0037] The flow regulating member 4 is in contact with the faucet body 7 and the valve seat 2 through the sealing member and is in gap with them. By setting the gap between the flow regulating member 4, the faucet body 7 and the valve seat 2, the flow regulating member 4 can be easily rotated by the user, and the sealing member is further used to prevent the water from flowing out of the flow regulating member 4 and the faucet body 7, and prevent the water from flowing out of the gap between the flow regulating member 4 and the valve seat 2. In a preferred embodiment, the gap between the outer circumference of the flow regulating member 4 and the faucet body 7 is about 0.1-0.3mm, and the gap between the inner circumference and the valve seat 2 is about 0.1-0.3mm, so that it has enough space to rotate, and the seal will not be unable to be completely sealed due to the large gap.

[0038] The force-applying member 5 includes a body, a gripping portion, and a button opening. The outer periphery of the body is a columnar structure, and a receiving groove extending in the axial direction is provided at the center thereof. The gripping portion is formed on the outer periphery of the body, and has ribs extending in the axial direction along the circumference to facilitate force-applying rotation. The button opening is used for the button 6 to pass through and be connected to the switch valve 3. A plurality of elastic arms extending toward the button 6 are arranged on the switch valve 3, and the ends of the elastic arms have hooks for hooking the button 6.

[0039] The present invention further provides a faucet, which includes the faucet body 7 and the push switch module 1 described in any of the above embodiments, and its structure will not be described in detail here.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
