DETAILED DESCRIPTION

[0040] The following combination Figures 1-16 The utility model is described in detail.

[0041] A self-resetting handle device includes a handle 10, which is provided with a first connecting position 401; and also includes a valve core seat 30, which is provided with a second connecting position 402. The first connecting position 401 is rotatably connected to the second connecting position 402, and the rotation axis formed by the first connecting position 401 rotating around the second connecting position 402 constitutes a first rotation axis 1301. The handle 10 is also provided with a second rotation axis 1302 perpendicular to the first rotation axis 1301, and the valve core seat 30 is also used to connect the valve stem 1101, and the second rotation axis 1302 is coaxially arranged with the rotation axis of the valve stem 1101; an elastic reset member is provided between the handle 10 and the valve core seat 30, and the elastic reset member allows the handle 10 to be rotated and reset in the opposite direction of its pressing and rotating direction, that is, when the external force acting on the handle 10 disappears, the handle 10 rotates to the initial position under the elastic force of the elastic reset member, realizing the self-resetting function of the handle 10, thereby improving the user experience.

[0042] In this embodiment, Figure 3 As shown, the elastic return member includes a first return spring 501 and a second return spring 502, and the first return spring 501 and the second return spring 502 are respectively arranged on both sides of the first rotation axis 1301. If the first return spring 501 and the second return spring 502 are located on the same side of the first rotation axis 1301, the return force provided by the first return spring 501 and the second return spring 502 will be concentrated on one side of the handle 10. When the external force disappears, the outer end face of the handle 10 will be in an inclined state, affecting the appearance.

[0043] In this embodiment, the handle 10 forms a lever structure with the rotation axis of the first connection position 401 as the fulcrum. Based on the lever principle, that is, the product of the power and the power arm is equal to the product of the resistance and the resistance arm, the first return spring 501 and the second return spring 502 can be compression springs with exactly the same specifications, or they can be compression springs with different specifications.

[0044] In this embodiment, the first return spring 501 and the second return spring 502 have identical specifications, and the distances between their central axes and the first rotation axis 1301 are equal, ensuring balanced force on the handle 10 and keeping the outer end surface of the handle 10 vertical when closed, thus enhancing its aesthetics. In other embodiments, the first return spring 501 and the second return spring 502 have different specifications, with the return spring providing greater elasticity being closer to the first rotation axis 1301 and the return spring providing less elasticity being farther away from the first rotation axis 1301, thereby satisfying the principle of leverage and similarly ensuring balanced force on the handle 10.

[0045] In this embodiment, the handle 10 includes a main body 101 and a lever 102 connected to one side of the main body 101. The extension line of the central axis of the lever 102 is perpendicular to the first rotation axis 1301. The first return spring 501 and the second return spring 502 are arranged in the main body 101 and are located on the extension line of the central axis of the lever 102, so that the pressing force acting on the lever 102 and the return force provided by the return spring are on the same plane, thereby improving the return effect.

[0046] In this embodiment, Figure 3-Figure 5 As shown, two guide posts 70 are provided in the main body 101, and the first return spring 501 and the second return spring 502 are sleeved outside the guide posts 70 to prevent the first return spring 501 and the second return spring 502 from being offset in their installation positions when they are compressed or stretched, thereby affecting the self-reset function.

[0047] In this embodiment, Figure 3 As shown, the valve core seat 30 has a through-hole 303 for movably inserting the guide post 70. When the handle 10 is pressed, the guide post 70 abuts against the switch that controls the opening and closing of the water flow. The valve core seat 30 also has a mounting hole 301 for inserting the valve stem 1101 and a fixing hole 302 connected to the mounting hole 301. The fixing hole 302 is threadedly engaged with a fastener, which locks the valve stem 1101 into the mounting hole 301.

[0048] In this embodiment, one of the first and second connection points 401 and 402 is a cylindrical groove with an opening. The width dimension L1 of the opening is less than the maximum width dimension of the cylindrical groove, that is, the diameter L2 of the cylindrical groove. The other is a cylindrical protrusion that rotates coaxially with the cylindrical groove to prevent the cylindrical protrusion from dislodging from the cylindrical groove. Specifically, the first connection point 401 is a cylindrical groove, the axis of which constitutes the first rotation axis 1301, and the second connection point 402 is a cylindrical protrusion. The valve core seat 30 is provided with a boss 305, and the cylindrical protrusion is connected to the boss 305. The width dimension L3 of the boss 305 is less than the width dimension L1 of the opening.

[0049] This embodiment further includes a fixed seat 20, which is connected to the handle 10. The fixed seat 20 has a first connection position 401 and is rotatable inwardly and outwardly relative to a vertical plane. Inward rotation refers to the lever 102 rotating away from the user, while outward rotation refers to the lever 102 rotating toward the user. The fixed seat 20 has a first abutment surface A6011 and a first abutment surface B6012, which are disposed on either side of the first connection position 401. The valve core seat 30 has a second abutment surface A6021 and a second abutment surface B6022, which are disposed on either side of the boss 305. The gap between the fixed seat 20 and the valve core seat 30 constitutes a clearance space 80 for the rotation of the fixed seat 20. Therefore, the inward and outward rotation angles of the handle 10 depend on the size of the clearance space 80. The larger the clearance space 80, the greater the rotation angle. Conversely, the smaller the clearance space 80, the smaller the rotation angle. The size of the clearance space 80 can be adjusted according to actual conditions during use. Considering that if the clearance space 80 is too large, the rotation angle of the handle 10 will be too large, affecting the user experience. If the rotation angle is too large, it will cause excessive pressure on the switch that controls the water flow, shortening its service life. Therefore, the inward and outward rotation angles of the handle 10 are both 5 degrees.

[0050] Specifically, if Figure 15 As shown, the lever 102 is pressed inwards, causing the fixing base 20 to rotate inwards until the first abutting surface A6011 abuts against the second abutting surface A6021, and the lever 102 stops rotating. The rotation angle of the lever 102 is B1, that is, B1 = 5°. Figure 16 As shown, the lever 102 is pressed outward, causing it to rotate the fixing seat 20 outward until the first abutment surface B6012 abuts the second abutment surface B6022. The lever 102 then stops rotating. The rotation angle of the lever 102 is B2, i.e., B2 = 5°. In this embodiment, the fixing seat 20 is locked to the body 101 via a fastener. The body 101 is provided with a connection hole 1011 that is threadably compatible with the fastener. The valve core seat 30 is provided with an operating position 304 for tightening the fastener, improving installation efficiency.

[0051] This embodiment also provides a water tap 90, such as Figure 12-16 As shown, it includes a base 100, a mixing valve 110 is provided in the base 100, and also includes the self-resetting handle device as mentioned above. The valve stem 1101 of the mixing valve 110 is connected to the valve core seat 30, and the switch for controlling the opening and closing of water outlet includes a first switch 1201 and a second switch 1202 provided in the base 100. Furthermore, the first switch 1201 and the second switch 1202 are respectively provided with contact buttons, and the front ends of the two guide columns 70 are provided with contacts for abutting the contact buttons.

[0052] When in use, the handle 10 is rotated to rotate around the second rotation axis 1302, thereby driving the valve core seat 30 to rotate, thereby rotating the valve stem 1101 of the mixing valve 110 to achieve mixing of cold water and hot water. The maximum rotation angle is A, A = 110°. Figure 14 At the same time, when the handle 10 is in a vertical state, that is, Figure 12 In the state shown, by pressing the handle 10 inward or outward, the handle 10 rotates around the first rotation axis 1301, as shown in FIG. Figure 15 and Figure 16 As shown, the contact at the front end of the guide column 70 triggers the contact button of the first switch 1201 or the second switch 1202, turning on the water faucet 90 to discharge water. When the external force acting on the handle 10 disappears, the handle 10 rotates to the initial position under the elastic force of the elastic reset member, closing the water faucet 90 to discharge water.
