[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] (1) The valve core switch of the utility model includes a bushing, a first rotating shaft arranged on the left and right sides of the bushing, a push piece, and two first C-shaped slots arranged on the push piece. When the push piece is pressed downward, the push piece moves vertically downward and drives the bushing and the valve core rod to rotate downward through the first C-shaped slot, and the bushing slides outward along the valve core rod to open the valve core opening; when the push piece is pulled upward, the push piece moves upward and drives the bushing and the valve core rod to rotate upward through the first C-shaped slot, and the bushing slides inward along the valve core rod until the valve core rod is in a horizontal position, and the valve core opening is closed. The present application buffers the force process of the valve core rod through the cooperation of the bushing and the push piece, thereby ensuring the switch feel and service life. At the same time, there are fewer parts, simple assembly, and reduced risks of abnormalities.

[0019] (2) The valve core rod of the utility model is a polygonal rod, and a polygonal hole is provided on the bushing, so that the bushing can only slide axially along the valve core rod but cannot rotate around the axis, thereby improving the stability of the switch structure.

[0020] (3) The push-pull member of the utility model includes a pressing part, a guiding part and a connecting part. The mounting bracket includes a notch extending up and down. Guide grooves are provided on both sides of the notch. The guiding part includes sliding blocks located on both sides of the pressing part. The sliding blocks are vertically slidably connected in the guiding grooves, thereby realizing the vertical up and down movement of the pull rod. When the pressing part is pushed to slide, the push-pull member can only move in the direction of the guiding groove due to the restriction of the guiding groove. When the push-pull member moves, the first C-shaped slot thereon also moves synchronously. The movement of the push-pull member is converted into the sliding of the bushing. When a certain stroke is reached, the bushing can no longer slide, and then the bushing drives the valve core rod to rotate. At this time, the bushing can slide a certain stroke again until the valve stem rotates to the limit position, that is, the valve core is in the fully open position; and when the push-pull member is pushed in the reverse direction, the bushing drives the valve core rod to rotate in the reverse direction until the valve core rod rotates to the limit position, that is, the valve core rod is in the fully closed position.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0032] The following is combined with Figure 1 To Attachment Figure 8 And specific embodiments discuss the utility model in detail.

[0033] like Figure 1-8As shown, the utility model provides a valve core switch, which can be used for water circuit switches in water heating and bathrooms, but is not limited thereto. The valve core switch includes a valve core 1, a bushing 2 and a push-pull member 3, wherein the valve core 1 includes a valve core body 11 and a valve core rod 12, the valve core body 11 is formed with a valve core opening, the valve core rod 12 is movably arranged in the valve core opening to open or close the valve core opening, and the valve core rod 12 extends out of the valve core opening and opens the valve core opening when one end of the valve core rod 12 rotates downward from a horizontal position, and closes the valve core opening when it returns to a horizontal position; a through hole matching the valve core rod 12 is formed on the bushing 2, and the bushing 2 is sleeved on the valve core rod 12 through the through hole, The liner 2 can slide axially along the valve core rod 12, but cannot rotate relatively. The left and right sides of the bushing 2 are convexly provided with a coaxially arranged first rotating shaft 21. The two sides of the pusher 3 are respectively formed with a first C-shaped slot 31 extending in the direction of the first rotating shaft 21. The bushing 2 is rotatably connected in the first C-shaped slot 31 through the first rotating shaft 21. When the pusher 3 is pressed downward, the pusher 3 moves vertically downward and drives the bushing 2 to slide and the valve core rod 12 to rotate through the first C-shaped slot 31, so that the valve core opening is opened. When the pusher 3 is pushed upward in the opposite direction, the bushing 2 drives the valve core rod 12 to rotate in the opposite direction until the valve core rod 12 rotates to the limit position, and the valve core opening is closed.

[0034] In one embodiment, the valve core rod 12 is a polygonal rod, a polygonal hole matching the polygonal rod is formed on the bushing 2, and the first rotating shaft 21 is arranged on the left and right sides of the polygonal hole. Optionally, the valve core rod 12 is a hexagonal rod, an octagonal rod, etc., and correspondingly, the polygonal hole is a hexagonal hole, an octagonal hole, etc., but it is not limited to this. As long as the valve core rod 12 and the bushing 2 can only slide relative to each other but cannot rotate relative to each other, it belongs to the protection scope of this application.

[0035] In a preferred embodiment, see Figure 3 , Figure 8 The valve core rod 12 is a square rod, a square hole matching the square rod is formed on the bushing 2, and the first rotating shaft 21 is arranged on the left and right sides of the square hole. Since the first rotating shaft 21 rotates in the first C-shaped slot 31, the first rotating shaft 21 is preferably a cylindrical rotating shaft, so that the bushing 2 rotates more smoothly in the first C-shaped slot 31, and the firmness of the structure can be ensured, so that the operator will not make an error in operation.

[0036] Specifically, in some embodiments, see Figure 7 As shown, the pusher 3 includes a pressing portion 32, a guide portion 33 and a connecting portion 34 which are connected in sequence. The pressing portion 32 is a force-applying portion, and a user applies force to the pressing portion 32 to drive the guide portion 33 and the connecting portion 34 to move synchronously. There are two connecting portions 34, which are symmetrically arranged on the left and right sides of the guide portion 33, and each connecting portion 34 is provided with a first C-shaped slot 31. Pressing the pressing portion 32 downward causes the connecting portion 34 to move vertically up and down along with the guide portion 33.

[0037] Specifically, in some embodiments, see Figures 4 to 6 , and also includes a mounting bracket 4, which has a notch 41 extending up and down. The pressing portion 32 is located on the outside of the notch 41 and moves up and down along the notch 41. The guiding portion 33 and the connecting portion 34 are located on the inside of the notch 41.

[0038] Specifically, a vertically extending guide groove 42 is provided on the inner side surface of the mounting bracket 4 adjacent to the bushing 2, and a guide groove 42 is provided on the left and right sides of the notch 41, respectively. The guide portion 33 includes sliding blocks located on both sides of the pressing portion 32, and the sliding blocks are vertically slidably connected in the guide groove 42. Restricted by the guide groove 42, the pusher 3 can only move in the direction of the guide groove 42. When the pusher 3 is pushed downward, the first C-shaped slot 31 on the connecting portion 34 also moves synchronously, and converts the movement of the pusher 3 into the sliding of the bushing 2. When the bushing 2 slides to a certain stroke, the bushing 2 can no longer slide, and then the bushing 2 drives the valve core rod 12 to rotate downward. At this time, the bushing 2 can slide again for a certain stroke until the valve core rod 12 rotates to the limit position, that is, the valve core opening is fully opened; when the pusher 3 is pushed upward in the reverse direction, the bushing 2 drives the valve core rod 12 to rotate in the reverse direction until the valve core rod 12 rotates to the limit horizontal position, that is, the valve core opening is fully closed.

[0039] Specifically, it also includes an installation body 5, in which a valve core positioning hole is provided, a valve core positioning column 14 is provided on the side of the valve core 1 away from the valve core rod 12, the valve core positioning column 14 is installed in the valve core positioning hole, and a valve core pressure cover 13 is locked on the valve core 1, and then the valve core 1 is assembled on the installation body 5. Because the valve core pressure cover 13 presses the valve core shell to prevent it from loosening, ensuring good sealing, the valve core 1 cannot rotate, while the valve core rod 12 can be moved normally.

[0040] Specifically, the front end of the mounting body 5 is provided with a mounting hole 51 matching with the mounting bracket 4, the top of the mounting hole 51 is provided with a second C-shaped slot (not shown in the figure), the top of the mounting bracket 4 is provided with a second rotating shaft 43 rotatably connected in the second C-shaped slot, and the mounting bracket 4 can rotate with the second rotating shaft 43; the lower part of the mounting bracket 4 is provided with a snap 44, and the snap 44 snaps on the edge of the mounting body 5. The mounting bracket 4 equipped with the push-pull member 3 is assembled in the second C-shaped slot of the mounting body 5 through the second rotating shaft 43, and then the mounting bracket 4 is pressed toward the mounting body 5, and the snap 44 at the lower end of the mounting bracket 4 will contact the edge of the mounting body 5, and continue to press to produce elastic deformation. When pressed in place, the snap 44 just grabs the edge of the mounting body 5. In the assembly process of the mounting bracket 4, the first rotating shaft 21 on the bushing 2 is just snapped into the first C-shaped slot 31, so that the bushing 2 and the push-pull member 3 are connected as one.

[0041] It can be understood that the present application utilizes the elastic deformation characteristics of the material. After being assembled in place, the parts can be assembled into a whole, and a stable state can be maintained without the use of screws. When an abnormality occurs, maintenance and replacement are more convenient.

[0042] Specifically, in some embodiments, see Figure 1 , and also includes a decorative panel 6, which is assembled on the outside of the mounting bracket 4. A through hole 61 is provided on the decorative panel 6 for the pressing portion 32 to extend out. The upper surface of the through hole 61 is a first limiting surface 62, and the lower surface of the through hole 61 is a second limiting surface 63. When the pressing portion 32 contacts the first limiting surface 62, the valve core opening is in a closed state, and when the pressing portion 32 contacts the second limiting surface 63, the valve core opening is in an open state. The through hole 61 on the decorative panel 6 only leaves room for the pusher 3 to move, ensuring that no interference occurs during movement. After the mounting bracket 4 is assembled, the decorative panel 6 is mounted on the mounting body 5 to complete the assembly of the valve core switch.

[0043] The installation process of the valve core switch of the present application is as follows: first, assemble the bushing 2 onto the valve core rod 12 of the valve core 1; then, install the guide portion 33 of the push-pull member 3 along the guide groove 42 of the mounting bracket 4 to form an assembly, and then assemble the second shaft 43 of the mounting bracket 4 in the assembly into the second C-shaped groove of the mounting body 5; finally, press the assembly toward the mounting body 5 to deform the snap 44, and after it is in place, the snap 44 just catches the shell edge of the mounting body 5, and during the pressing and assembling process, the first shaft 21 of the bushing 2 just catches the first C-shaped groove 31 of the push-pull member 3, and then assemble the decorative panel 6 to complete the installation. The overall structure is simple, with few parts and simple assembly, which not only reduces the manufacturing cost, but also reduces the risk of abnormality.

[0044] The utility model also provides a shower, comprising any one of the above-mentioned valve core switches. The shower provided in this application adopts all technical solutions of all the above-mentioned valve core switch embodiments, and therefore at least has all the beneficial effects brought by the technical solutions of the valve core switch embodiments, which will not be described one by one.

[0045] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
