Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] The technical solutions provided by each embodiment of the present invention will be described in detail below in conjunction with the drawings.

[0038] A self-cleaning component of a toilet spray gun is disclosed in an embodiment of the present invention. As Figure 1 shown, the self-cleaning component includes a self-cleaning bracket 1 and a self-cleaning nozzle 2; wherein, the self-cleaning bracket 1 can be fixed on the toilet spray gun and is used to support and fix the self-cleaning nozzle 2.

[0039] Specifically, as Figure 2 and Figure 12 shown, an opening 3 is formed on the self-cleaning nozzle 2, enabling the toilet spray gun 22 to pass through the self-cleaning nozzle 2 from the opening 3, that is, the self-cleaning nozzle 2 can surround the toilet spray gun 22; as Figure 3 , Figure 7 , Figure 9 and Figure 12As shown in the figure, the self-cleaning nozzle 2 above the opening 3 is provided with upper spray holes 4. Through the upper spray holes 4, the upper side of the toilet spray gun 22 can be cleaned. Then the cleaning water flows through both sides of the toilet spray gun 22 to achieve the cleaning of both sides of the toilet spray gun 22. The self-cleaning nozzle 2 below the opening 3 is provided with lower spray holes 5. Through the lower spray holes 5, the lower side of the toilet spray gun 22 can be cleaned, thereby realizing the 360° circumferential cleaning of the toilet spray gun 22. Among them, the number and position arrangement of the upper spray holes and the lower spray holes can be set as needed. As Figure 3 shown, the self-cleaning nozzle 2 is provided with a self-cleaning water inlet 6. A self-cleaning water channel is formed inside the self-cleaning nozzle 2. The self-cleaning water inlet 6 is communicated with the upper spray holes 4 and the lower spray holes 5 respectively through the self-cleaning water channel. In this way, the self-cleaning water flows from the self-cleaning water inlet 6 into the self-cleaning water channel, and then is divided into the upper spray holes 4 and the lower spray holes 5 through the self-cleaning water channel, and is ejected from the upper spray holes 4 and the lower spray holes 5.

[0040] In addition, as Figure 5 and Figure 13 shown, an inlet channel 7 is provided inside the self-cleaning bracket 1. The inlet channel 7 can be communicated with the water inlet pipeline of the intelligent toilet through a water pipe, so that the self-cleaning water flows into the self-cleaning water inlet 6 through the inlet channel 7; as Figures 1 to 5 shown, an n-shaped cavity is formed on the self-cleaning bracket 1. A sliding groove 8 is provided on the inner cavity wall of the n-shaped cavity. The sliding groove 8 is specifically arranged on the two side walls of the n-shaped cavity. Sliding arms 9 are provided on both sides of the self-cleaning nozzle 2 and are matched with the sliding groove 8. By inserting the sliding arms 9 into the sliding groove 8, the self-cleaning nozzle 2 can be inserted into the n-shaped cavity to realize the detachable connection between the self-cleaning nozzle 2 and the self-cleaning bracket 1. At this time, the self-cleaning water inlet 6 is exactly corresponding to and communicated with the inlet channel 7. Among them, the positions of the sliding groove and the sliding arm can be interchanged.

[0041] It should be noted that as Figures 6 to 7 、 Figures 10 to 13 shown, the self-cleaning assembly is specifically fixed at the front end of the toilet spray gun 22, that is, at the position of the spray gun nozzle. When the toilet spray gun 22 retracts, the spray gun nozzle of the toilet spray gun 22 can be cleaned through the self-cleaning assembly; as Figure 8 and Figure 9 shown, during the process of the toilet spray gun 22 extending, the self-cleaning assembly can clean the slide rail on the lower side of the toilet spray gun 22, and the cleaning range is larger.

[0042] In summary, in the self-cleaning component of this embodiment, by providing an opening on the self-cleaning nozzle, the toilet spray gun can pass through the self-cleaning nozzle, and the self-cleaning nozzle is provided with upper spray holes and lower spray holes, so that the toilet spray gun can be rinsed in a 360° circular manner, and the cleaning is more thorough. In addition, by providing a chute and a sliding arm structure on the self-cleaning bracket and the self-cleaning nozzle respectively, the self-cleaning nozzle can be detachably fixed on the self-cleaning bracket, which is convenient for quickly replacing the self-cleaning nozzle, reducing the use cost of the toilet spray gun. Especially in areas with poor water quality, it avoids the situation of disassembling the machine to replace the whole toilet spray gun due to blockage of the self-cleaning component, reducing the impact on users, and the self-cleaning nozzle can be replaced regularly to ensure the hygiene and cleanliness of the toilet spray gun.

[0043] In this embodiment, as Figures 1 to 5 shown, buckle columns 10 are provided on both sides of the self-cleaning nozzle 2, and buckle holes 11 matching the buckle columns 10 are provided on the self-cleaning bracket 1, so that when the self-cleaning nozzle 2 is inserted into the n-shaped cavity, the buckle columns 10 are buckled into the buckle holes 11. Specifically, when the self-cleaning nozzle 2 is completely inserted into the n-shaped cavity on the self-cleaning bracket 1 through the chute 8 and the sliding arm 9 structure, the buckle columns 10 are just buckled into the buckle holes 11. In this way, it can not only prevent the self-cleaning nozzle 2 from falling off the self-cleaning bracket 1, but also facilitate the quick disassembly of the self-cleaning nozzle 2 from the self-cleaning bracket 1. Among them, the buckle holes can be replaced with buckle grooves.

[0044] And, as Figures 2 to 5 shown, a positioning block 12 is provided at the upper end of the self-cleaning nozzle 2, and a positioning hole 13 matching the positioning block 12 is provided on the self-cleaning bracket 1. When the self-cleaning nozzle 2 is inserted into the n-shaped cavity on the self-cleaning bracket 1, the positioning block 12 at the upper end of the self-cleaning nozzle 2 is just inserted into the positioning hole 13, realizing the positioning connection between the upper end of the self-cleaning nozzle 2 and the self-cleaning bracket 1.

[0045] Furthermore, as Figures 1 to 4 、 Figure 12 shown, the self-cleaning nozzle 2 includes a flow channel body 2-1 and a self-cleaning cover 2-2.

[0046] Specifically, a water channel groove 14 is formed on the flow channel body 2-1, and the water channel groove 14 and the self-cleaning cover 2-2 form a self-cleaning water channel. A first fixing column 15 is provided on the flow channel body 2-1, and a first fixing hole 16 matching the first fixing column 15 is provided on the self-cleaning cover 2-2. The self-cleaning cover 2-2 is fixedly connected to the flow channel body 2-1 by inserting the first fixing column 15 into the first fixing hole 16. Among them, the number and positions of the first fixing column and the first fixing hole can be set according to needs.

[0047] And, as Figure 3 、 Figure 4 and Figure 12As shown in the figure, a shielding flange 17 extends from the edge of the water channel groove 14 to the outside of the water channel groove 14. A welding rib 18, which is arranged in a dislocation manner with respect to the shielding flange 17, extends from the self-cleaning cover 2-2, and the welding rib 18 is located on the outer periphery of the shielding flange 17. When the flow channel body 2-1 is connected to the self-cleaning cover 2-2, the self-cleaning cover 2-2 is welded and fixed to the flow channel body 2-1 through the welding rib 18, ensuring the sealing performance of the connection between the flow channel body 2-1 and the self-cleaning cover 2-2. The shielding flange 17 is located between the welding rib 18 and the water channel groove 14, and can effectively prevent the welding adhesive from entering the water channel groove 14.

[0048] In this embodiment, as Figure 3 , Figure 9 and Figure 12 shown, the upper spray hole 4 faces the rear of the opening 3. A water baffle 23 that is inclined downward is provided on the bracket of the toilet spray gun 22, so that the water flow ejected from the upper spray hole 4 changes direction downward after colliding with the water baffle 23. After the water flow ejected from the upper spray hole 4 collides with the water baffle 23, it will disperse downward, and can uniformly clean the upper side and both sides of the toilet spray gun 22. The lower spray hole 5 faces the upper side of the opening 3, and can clean the lower side of the toilet spray gun 22. Of course, in other embodiments, the water baffle can also be arranged on the self-cleaning bracket behind the upper spray hole.

[0049] And, as Figure 5 shown, a second fixing hole 19 is provided on the self-cleaning bracket 1, and the second fixing hole 19 can cooperate with the second fixing column on the bracket of the toilet spray gun, that is, by inserting the second fixing column into the second fixing hole 19, the self-cleaning bracket 1 is fixed on the bracket of the toilet spray gun.

[0050] In addition, as Figure 5 shown, a positioning groove 20 is provided on the inner cavity wall of the n-shaped cavity, and the positioning groove 20 can cooperate with the positioning arm on the bracket of the toilet spray gun. By inserting the positioning arm into the positioning groove 20, the positioning of the self-cleaning bracket 1 on the bracket of the toilet spray gun is realized, and when the self-cleaning bracket 1 is fixedly connected to the bracket of the toilet spray gun, the shaking between the two is prevented, thereby increasing the connection stability.

[0051] Furthermore, as Figure 13 shown, a sealing member 21 is provided between the self-cleaning water inlet 6 and the water inlet channel 7. When the self-cleaning water inlet 6 and the water inlet channel 7 are in position correspondence, the sealing member 21 can achieve the sealing between the two. Among them, the sealing member can be a sealing ring.

[0052] Another embodiment of the present invention discloses a toilet spray gun, which specifically includes a bracket assembly, a spray gun assembly, a driving assembly, and the self-cleaning assembly of the toilet spray gun in the above embodiment.

[0053] Specifically, a slide rail is provided at the upper end of the bracket assembly, and a chute cooperating with the slide rail is provided at the lower end of the spray gun assembly, enabling the spray gun assembly to slide on the bracket assembly. A driving assembly is used to drive the sliding of the spray gun assembly, and a self-cleaning assembly is arranged at one end of the bracket assembly away from the driving assembly. This toilet spray gun can perform 360° circumferential flushing, with cleaner cleaning. Moreover, the self-cleaning nozzle can be quickly disassembled and replaced from the toilet spray gun, reducing the usage cost of the toilet spray gun and making it more hygienic to use.

[0054] The above is only the specific implementation manner of the present invention. Under the above teaching of the present invention, those skilled in the art can make other improvements or deformations based on the above embodiments. Those skilled in the art should understand that the above specific description is only a better explanation of the purpose of the present invention, and the protection scope of the present invention should be subject to the protection scope of the claims.
