Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a water outlet switching structure and a faucet. Background Technique

[0002] A cup washer is a device for cleaning cups. It has various types and designs. Commonly, it generates high-pressure water flows in multiple directions through a pressing action to wash the cups. The operation process is very simple and does not require tools such as brushes, making the cleaning process efficient and convenient.

[0003] In traditional kitchen sinks, the cup washer and the faucet are independent entities and are respectively installed at two positions on the side of the sink, resulting in an increase in the user's equipment cost.

[0025] In order to further explain the technical solution of the utility model, the utility model will be elaborated in detail below through specific embodiments.

[0026] Referring to Figures 1-4 as shown, the utility model discloses a water outlet switching structure, including a valve body 1, an annular part 2, a water passing part 3 and a spool assembly;

[0027] The circumferential surface of the valve body 1 is provided with a water passing groove 11 and several first convex teeth 12; during use, water can flow out of the water passing groove 11 to realize water supply; the water passing groove 11 and the first convex teeth 12 are located at adjacent positions in the axial direction of the valve body 1;

[0028] The annular member 2 is rotatably sleeved on the circumferential surface of the valve body 1 in a dynamically sealed manner and covers the water passing groove 11, so that a water channel (the space between the water passing groove 11 and the annular member 2) is formed between the valve body 1 and the annular member 2; the circumferential surface of the annular member 2 is provided with a water outlet hole 21;

[0029] The water inlet end of the water passing member 3 is fixedly opposed to the water outlet hole 21, a water passing channel 31 is arranged therein, and a movable hole 32 communicated with the water passing channel 31 is arranged on the surface of the water passing member 3;

[0030] The valve core assembly is rotatably and dynamically sealed and fitted in the movable hole 32 to realize the on-off between the two ends of the water passing channel 31; a plurality of second convex teeth 41 meshing with the first convex teeth 12 are arranged on the circumferential surface of the end part of the valve core assembly exposed out of the movable hole 32.

[0031] Through the above scheme, in the present utility model, the water passing member 3 swings left and right with the valve body 1 as the axis, and the valve core assembly in the water passing member 3 can be linked through the meshing of the first convex teeth 12 and the second convex teeth 41, so that the valve core assembly realizes the on-off between the two ends of the water passing channel 31. When the valve core assembly is in the open state, the product supplies water through the water passing groove 11 and the water passing channel 31 in sequence. When the valve core assembly is in the closed state, the water passing channel 31 cannot supply water; this structure can be applied to a faucet integrated with a cup washer. The valve body 1 is the valve body (or valve seat) inside the faucet, and the water passing member 3 is arranged inside the cup washer and communicated with the nozzle of the cup washer. When the user swings the cup washer, the opening and closing of the water inlet end of the cup washer can be realized, and in the closed state, the situation that the user is wetted by high-pressure water due to accidentally touching the button of the cup washer can be prevented.

[0032] The following shows specific embodiments of the present utility model.

At this time, the internal valve core assembly will maintain the corresponding state and will not change until the second convex teeth 41 mesh with the first convex teeth 12 again after the subsequent swing of the water passing member 3.

[0034] The above-mentioned spool assembly includes a spool 4, a first spring 5, and two sealing balls 6; a second convex tooth 41 is provided on the circumferential surface of one end of the spool 4, and the other end thereof is movably and sealingly fitted in the movable hole 32, and a cross hole 42 penetrating to the circumferential surface of the spool 4 is provided; the first spring 5 is arranged in the cross hole 42, and sealing balls 6 are arranged at both ends thereof. That is to say, the spool assembly is actually a sealing ball ball valve, and the connection between the water passage 31 and the movable hole 32 is conducted or closed by the sealing ball 6 under the elastic force of the first spring 5, so as to realize the on-off between both ends of the water passage 31. In this embodiment, the sealing ball 6 is made of rubber material, and its elasticity can ensure the sealing and leak-proof effects.

[0035] Furthermore, a buckle 43 is provided on the end face of one end of the spool 4, and the buckle 43 is hooked at the port of the movable hole 32 to realize the relative fixation between the spool 4 and the water passing member 3.

[0036] The utility model further includes a supporting platform 7 sleeved on the circumferential surface of the annular member 2 at one end, and a nozzle 8 and a button 9 arranged on the upper surface of the supporting platform 7; the water passing member 3 is arranged in the supporting platform 7, so that the supporting platform 7 and the water passing member 3 can swing synchronously; the nozzle 9 is communicated with the water passage 31 of the water passing member 3; the button 9 is used to realize the on-off of the water path between the nozzle 9 and the water passing member 3. The water passing member 3, the spool assembly, the supporting platform 7, the nozzle 8 and the button 9 can form a basic cup washer, and the water outlet of the nozzle 8 is realized by pressing the button 9.

[0037] Secondly, the utility model further includes a water outlet member 10, a piston rod 20, and a second spring 30; the water inlet end of the water outlet member 10 is connected to the water outlet end of the water passing member 3, and the nozzle 9 is installed at the water outlet end of the water outlet member 10; the piston rod 20 movably and sealingly penetrates through the water outlet member 10 to connect or block both ends of the water outlet member 10; the second spring 30 is used to provide an elastic force to block both ends of the water outlet member 10 by the piston rod 20; the button 9 is connected to the end of the piston rod 20.

[0038] Furthermore, the utility model further includes a limiting plate 40; an installation groove 71 is formed by recessing the lower surface of the supporting platform 7, and the water passing member 3 and the water outlet member 10 are both fitted in the installation groove 71; the limiting plate 40 is locked in the supporting platform 7 to limit the water outlet member 10. Thus, it is convenient to disassemble and assemble the water passing member 3 and the water outlet member 10 directly on the lower surface of the supporting platform 7.

[0039] Meanwhile, the water outlet end of the water passing member 3 is embedded in the water inlet end of the water outlet member 10 and fixed by a C-shaped buckle 50.

[0040] It can be understood that since the annular member 2 and the water passing member 3 are relatively fixed, in actual production, the two can also be designed as an integrally formed single component.

[0041] On the circumferential surface of the above-mentioned valve body 1, annular grooves 13 are provided on both axial sides of the water passing groove 11. A sealing ring 60 is arranged in the annular groove 13, and the sealing ring 60 is elastically fitted between the annular groove 13 and the inner wall of the annular member 2 to realize the dynamic seal between the annular member 2 and the valve body 1. In addition, sealing accessories such as sealing rings and gaskets are also provided at other sealed parts in the present utility model to realize dynamic seal or static seal.

[0042] The present utility model also discloses a faucet, which applies the above-mentioned water outlet switching structure, and correspondingly also has the technical effects brought by the water outlet switching structure.

[0043] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the present utility model.
