[0025] To make the technical solution of this utility model clearer, the following description is in conjunction with the appendix. Figures 1 to 9 This specification provides a detailed description of the present invention. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the scope of protection of the present invention.

[0026] A dustproof nozzle cover includes a cover body 1, a nozzle assembly 2, and a dustproof cover assembly 3. The top center of the cover body 1 has a recessed sliding groove, with slide rails 11 on both sides of the sliding groove. One end of the sliding groove is open (for easy assembly and disassembly of the dustproof cover assembly 3), and the bottom wall of the sliding groove is recessed to form a receiving groove 10 for accommodating the nozzle assembly 2. The bottom of the receiving groove 10 has a water outlet 101 and a vent 102. The nozzle assembly 2 is rotatably connected to the receiving groove 10 near the center of the cover body 1. At one end, when the nozzle assembly 2 rotates and is stored in the receiving groove 10, the water outlet 101 and the vent 102 are closed, and it is in a closed state; when the nozzle assembly 2 rotates out of the receiving groove 10, the vent 102 is opened, and the water outlet 101 is connected to the water outlet channel 20 of the nozzle assembly 2, and it is in an open state; the dust cover assembly 3 can be slidably mounted on the slide rail 11; and the dust cover assembly 3 can drive the nozzle assembly 2 to rotate and be stored in the receiving groove 10, and close the receiving groove 10.

[0027] It should be noted that a water outlet seal and a vent seal are respectively provided between the nozzle assembly 2 and the water outlet 101 and the vent 102. In this embodiment, the water outlet seal and the vent seal are integrally formed sealing components 4, and through holes are provided corresponding to the water outlet 101 and the vent 102. The sealing component 4 cooperates with the plug and the arc surface at the bottom of the nozzle assembly 2 to seal the vent 102 and the water outlet 101 respectively. This is prior art and will not be described in detail.

[0028] Specifically, the nozzle assembly 2 includes a nozzle body 21, with a water outlet channel 20 extending vertically through the nozzle body 21. The lower end of the nozzle body 21 is a cylindrical rotating part 211, with blind holes 212 at both ends of the rotating part 211. A fixed shaft 22 is rotatably mounted inside each blind hole 212. The outer surface of the fixed shaft 22 is provided with a protruding ring 221, and the inner wall of the blind hole 212 is provided with a corresponding annular groove 213. The protruding ring 221 is rotatably engaged in the annular groove 213. A limiting block 2 is provided at one end of the fixed shaft 22 that protrudes from the blind hole 212. 22. A limiting groove 103 is provided on the side wall of the receiving groove 10. The limiting block 222 cooperates with the limiting groove 103 to restrict the rotation of the fixed shaft 22. In this structure, only an elastic element (such as a torsion spring) is needed between the fixed shaft 22 and the nozzle body 21 to make the nozzle body 21 tend to open. The dust cover assembly 3 is opened by translation, and the nozzle body 21 can automatically pop out and open under the force of the elastic element. In this way, the opening and closing of the nozzle body 21 does not require the user to touch it with their hands, which is more hygienic and simpler to operate.

[0029] Specifically, the lower end of the limiting block 222 has a guide slope, and the upper end of the limiting groove 103 is provided with a locking block 104. The upper end of the locking block 104 is also provided with a guide slope. The setting of the guide slope makes it easy for the limiting block 222 to be locked into the limiting groove 103 and to be locked and restricted from moving upward by the locking block 104.

[0030] Specifically, the width of the annular groove 213 is greater than that of the convex ring 221, allowing the fixed shaft 22 to move inward and outward. The elastic element is a spring 23 located between the fixed shaft 22 and the bottom wall of the blind hole 212, and both ends of the spring 23 are provided with snap-fit ​​connectors 231. The bottom walls of the fixed shaft 22 and the blind hole 212 are respectively provided with a fixed shaft snap-fit ​​groove 223 and a blind hole snap-fit ​​groove 214. The snap-fit ​​connectors 231 are respectively snapped into the fixed shaft snap-fit ​​groove 223 and the blind hole snap-fit ​​groove 214, so that the spring 23 has a force that tends to open the nozzle body 21 and a force that tends to move the fixed shaft 22 outward. With this structure, firstly, the nozzle body 21 can be automatically popped out and opened; secondly, it is convenient to disassemble the nozzle assembly 2. When disassembling, it is only necessary to press the nozzle body 21 on one side. After the spring 23 is compressed, the fixed shaft 22 on the other side of the nozzle body 21 can be released from the restriction of the snap block 104, thereby removing the nozzle assembly 2 for easy cleaning.

[0031] Specifically, the dust cover assembly 3 includes a cover plate 31 and a first magnetic element 32; the bottom wall of the sliding groove is provided with a second magnetic element 12 corresponding to the first magnetic element 32; in the open state, the first magnetic element 32 and the second magnetic element 12 correspond to each other and attract each other to keep the dust cover assembly 3 in the open position.

[0032] Specifically, the dust cover assembly 3 can also be provided with a third magnetic component. In the closed state, the third magnetic component and the second magnetic component 12 correspond to each other and attract each other to keep the dust cover assembly 3 in the closed position. In order to save costs, the cover plate 31 is provided with protruding locking points 311 on both sides, and the slide rail 11 is provided with corresponding recessed points 111. In the closed state, the locking points 311 fall into the recessed points 111 and lock to keep the dust cover assembly 3 in the closed position.

[0033] Specifically, the first magnetic component 32, the second magnetic component 12, and the third magnetic component can be a combination of magnets and / or magnetic materials; the first magnetic component 32 (the third magnetic component) and the second magnetic component 12 can be integrally formed with the cover plate 31 or the cover body 1 by inlay injection molding; the first magnetic component 32 (the third magnetic component) and the second magnetic component 12 can also be placed in the grooves of the cover plate 31 or the cover body 1 respectively, and then sealed by the cover plate.

[0034] Specifically, the top surface of the cover 31 is also provided with a raised operating part 33, which makes it easy for the user to operate and move the dust cover assembly 3.

[0035] Specifically, it also includes a handle 5, the two ends of which are fixed to the outer wall of the cover body 1 by rivets 6.

[0036] Specifically, the mouthpiece body 21 can also be configured as a connecting part and a sucking part. The sucking part can be made of a flexible material (such as silicone) for contact with the user's lips. The flexible material has a better tactile feel. The sucking part and the connecting part are snapped together.
