Description

Technical Field

[0001] This utility model relates to a self-cleaning faucet. Background Technology

[0002] As a widely used water supply device in daily life, faucets play an important role in places such as kitchens and bathrooms. They use a handle to activate a valve core, allowing water to flow from the inlet to the outlet or be blocked from flowing out. However, traditional faucets tend to accumulate scale, stains, or residues at the outlet and surrounding area during use, especially in areas with hard water.

[0003] Currently, some faucet designs on the market have cleaning functions, such as adding spray holes, auxiliary rinsing structures, or built-in cleaning liquid storage chambers to achieve regular cleaning of the water outlet area. However, these solutions often have problems such as complex structure and inconvenient maintenance.

[0004] Therefore, how to effectively clean and flush the outlet and its surroundings by rationally setting the detergent introduction path without significantly changing the original structure has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a self-cleaning faucet that cleans the circumference of the faucet outlet by flushing the water outlet from the water flow channel to the water outlet side after the detergent / powder is loaded into the liquid sleeve.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing, a water outlet located on the front side of the housing, a water inlet located on the rear side of the housing, a valve core located between the water inlet and the water outlet of the housing, and a handle linked to the valve core. It also includes a liquid-filling sleeve integrally formed with the housing. The housing includes a water flow channel located between the water inlet and the water outlet. The liquid-filling sleeve includes a liquid-filling cavity, which is interconnected with the water flow channel. A cover is detachably installed on the top of the liquid-filling sleeve, and the upward projection of the liquid-filling cavity falls on the cover. A first sealing ring is fixedly installed inside the cover, abutting against the inner wall of the liquid-filling cavity.

[0007] The present invention is further configured such that: the liquid-filling sleeve is provided with a plurality of positioning blocks spaced apart circumferentially, and the cover is made of rubber and is provided with positioning slots for the corresponding positioning blocks to be inserted.

[0008] The present invention is further configured such that: the liquid-filling sleeve is provided with an installation groove for inserting a first sealing ring, the first sealing ring is inclined radially inward from top to bottom, and the liquid-filling sleeve includes a pressing part located above the first sealing ring.

[0009] The present invention is further configured to include a limiting module, the housing includes a connecting section, the water outlet is located on the connecting section and the filter screen is rotatably mounted on the connecting section, the limiting module consists of two pieces and is located on the left and right sides of the filter screen respectively, and each limiting module includes a limiting plug that is slidably mounted inside the filter screen.

[0010] The present invention is further configured such that: each of the limiting modules includes a positioning block fixed to the connecting section, a cooperating rod fixed to the limiting insert block, and a cooperating spring sleeved on the cooperating rod; each cooperating rod includes a positioning disc abutting against the positioning block; the positioning block includes a fixing plate; one end of the cooperating spring is fixed to the positioning insert block, and the other end is fixed to the fixing plate.

[0011] The present invention is further configured such that: the connecting segment is detachably connected to the housing; the connecting segment includes a connecting plate and a mounting post; the mounting post is inserted into the housing; and the connecting plate has a plurality of insertion holes along the circumferential direction; and the housing has screw holes corresponding to each insertion hole.

[0012] The present invention is further configured to include a second sealing ring located between the mounting post and the housing.

[0013] By adopting the above technical solution, after separating the liquid-filling sleeve from the cover, citric acid solution, special cleaning agent, and other items are poured into the liquid-filling chamber, and then the liquid-filling sleeve and cover are connected. At this time, under the action of gravity, the liquid in the liquid-filling chamber will flow downward and enter the water flow channel. Then, the handle is opened to allow water to flow from the inlet to the outlet. The liquid in the liquid-filling chamber will mix with the water flow in the water flow channel and move towards the outlet, thus impacting the circumference of the outlet. Under the action of water pressure and the action of the cleaning liquid components, the scale and residue around the outlet can be flushed away and separated from the shell, achieving self-cleaning of the faucet. Furthermore, due to the action of the first sealing ring, the water in the water flow channel cannot flow out through the connection between the cover and the liquid-filling sleeve, thus ensuring the sealing performance of the connection between the shell and the liquid-filling sleeve when the faucet is in use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-8 As shown, this utility model discloses a self-cleaning faucet, including a housing 1, a water outlet 31 located on the front side of the housing 1, a water inlet 11 located on the rear side of the housing 1, a valve core 12 located between the water inlet 11 and the water outlet 31 of the housing 1, and a handle 13 linked to the valve core 12. By rotating the handle 13, the ceramic discs inside the valve core 12 slide relative to each other, so that the water flow from the water inlet 11 can flow towards the water outlet 31. When it is necessary to turn off the faucet, force is applied to the handle 13 in the opposite direction to reset the ceramic discs inside the valve core 12. Water entering through inlet 11 cannot flow through valve core 12 to outlet 31, therefore water cannot flow out (this is prior art and will not be elaborated here). It also includes a liquid-holding sleeve 2 integrally formed with the housing 1. The housing 1 includes a water flow channel 14 located between inlet 11 and outlet 31. The liquid-holding sleeve 2 includes a liquid-holding cavity 21, which is connected to the water flow channel 14. A cover 22 is detachably installed on the top of the liquid-holding sleeve 2 by bolts, magnets, etc. The upward projection of the liquid-holding cavity 21 falls... On the cover 22, a first sealing ring 221 is fixedly installed inside the cover 22, abutting against the inner wall of the liquid-filling cavity 21. After separating the liquid-filling sleeve 2 from the cover 22, citric acid solution, special cleaning agent, and other items are poured into the liquid-filling cavity 21, and then the liquid-filling sleeve 2 and the cover 22 are connected. At this time, under the action of gravity, the liquid in the liquid-filling cavity 21 will flow downward and enter the water flow channel 14. At this time, the handle 13 is opened to allow water to flow from the inlet 11 to the outlet 31, and the liquid in the liquid-filling cavity 21 will... The water mixes with the water flow in the water flow channel 14 and moves toward the outlet 31, thus impacting the outlet 31 in a circumferential manner. At this time, under the action of water pressure and the action of the cleaning liquid components, the scale and residue around the outlet 31 can be flushed away and separated from the housing 1, realizing the self-cleaning of the faucet. Furthermore, due to the action of the first sealing ring 221, the water in the water flow channel 14 cannot flow out through the connection between the cover 22 and the liquid-filling sleeve 2, thus ensuring the sealing performance of the connection between the housing 1 and the liquid-filling sleeve 2 when the faucet is in use.

[0030] In addition, since detergents (especially acidic or alkaline solutions) may corrode metal materials, the materials of the housing 1 and the liquid-filling sleeve 2 need to have good chemical corrosion resistance, such as stainless steel, copper-nickel alloy, etc.

[0031] The liquid-filling sleeve 2 is provided with a plurality of positioning blocks 23 spaced apart around its circumference. The cover 22 is made of rubber and is provided with positioning slots 222 for the corresponding positioning blocks 23 to be inserted. Since the cover 22 is made of rubber and is prone to deformation, after the detergent is filled into the liquid-filling sleeve 2, an outward bending force is applied to the cover 22 so that each positioning block 23 on the liquid-filling sleeve 2 will fall into the corresponding positioning slot 222, thereby determining the relative position of the cover 22 and the liquid-filling sleeve 2. Specifically, the cover 22 cannot rotate or move up and down relative to the liquid-filling sleeve 2.

[0032] Preferably, the liquid-filling sleeve 2 is provided with an installation groove 24 for inserting the first sealing ring 221. The first sealing ring 221 is inclined radially inward from top to bottom. The liquid-filling sleeve 2 includes a pressing part 25 made of a deformable material such as rubber located above the first sealing ring 221. During the process of inserting the cover 22 into the liquid-filling sleeve 2, except for the need to bend the cover 22 to insert each positioning block 23 into the corresponding positioning slot 222, the first sealing ring 221 moves downward along the installation path of the cover 22. The cover 22 needs to be tilted over the corresponding holding part 25. At this time, due to the cooperation of each positioning block 23 and the positioning slot 222, the cover 22 cannot move relative to the liquid-filling sleeve 2. Since the top surface of the first sealing ring 221 abuts against the bottom surface of the holding part 25, the first sealing ring 221 is stably located below the holding part 25 without the action of external force. The water flow in the water channel cannot pass over the first sealing ring 221 and flow out from the connection position between the liquid-filling sleeve 2 and the cover 22, thereby improving the sealing between the cover 22 and the liquid-filling sleeve 2.

[0033] In addition, it also includes a limiting module 4. The housing 1 includes a connecting section 3. The water outlet 31 is located on the connecting section 3, and the connecting section 3 is rotatably mounted on the filter screen 32 around the water outlet 31. There are two limiting modules 4, which are located on the left and right sides of the filter screen 32 respectively. Each limiting module 4 includes a limiting block 41 that is slidably installed in the filter screen 32. 1. Since the connecting section 3 contains the filter screen 32, if the water flowing out of the water outlet 31 in the water flow channel 14 contains impurities with a diameter or volume larger than the holes of the filter screen 32, they will be intercepted by the filter screen 32. 1. The filter screen 32 cannot flow out through the filter screen 32; 2. Since the filter screen 32 is rotatably installed on the connecting section 3 and the limiting block 41 of the limiting module 4 inserts the filter screen 32, the filter screen 32 cannot rotate under the restriction of each limiting block 41 without the action of external force. When cleaning is required, after applying force to the limiting module 4 to make each limiting block 41 move radially outward, the water pressure can drive the filter screen to rotate during the process of turning the handle 13 to make the water flow out, thereby flushing the front and back sides of the filter screen and causing the impurities attached to the inner side of the filter screen 32 to fall off.

[0034] Each of the limiting modules 4 includes a positioning block 41 fixed to the connecting section 3, a cooperating rod 43 fixed to the limiting insert 41, and a cooperating spring 44 sleeved on the cooperating rod 43. Each cooperating rod 43 includes a positioning disk 431 that abuts against the positioning block 41. The positioning block 41 includes a fixing plate 421. One end of the cooperating spring 44 is fixed to the positioning insert 23, and the other end is fixed to the fixing plate 421. 1. When it is necessary to rotate the filter screen 32, a radially outward force is applied to the positioning disk 431, causing the cooperating rod 43 to move radially outward, driving the limiting insert 41 to move out of the filter screen 32. At the same time, the cooperating spring 44 is compressed. At this time, under the action of water flow... 1. It can drive the filter screen 32 to rotate and flush its inner and outer sides; 2. Because the cooperating spring 44 has its own elasticity, when the filter screen 32 does not need to be rotated, the force on the positioning plate 431 is released. After the external force is lost, the elasticity of the cooperating spring 44 will drive it and the cooperating rod 43 to move radially inward. As the cooperating rod 43 moves inward, the corresponding positioning block 41 can insert the filter screen 32. At this time, the filter screen 32 cannot rotate; 3. Since the positioning plate 431 and the positioning block 41 abut against each other, the positioning plate 431 cannot move radially inward, which can limit the path range of the cooperating rod 43 and the cooperating spring 44 during the sliding process.

[0035] The connecting section 3 is detachably connected to the housing 1. The connecting section 3 includes a connecting plate 33 and a mounting post 34. The mounting post 34 is inserted into the housing 1, and the connecting plate 33 has a plurality of insertion holes 331 arranged circumferentially. The housing 1 is provided with screw holes 15 corresponding to each insertion hole 331. When connecting the connecting section 3 and the housing 1, a bolt that matches the type of screw hole 15 is inserted into the insertion hole 331 and threaded into the screw hole 15 to achieve the connection between the connecting section 3 and the housing 1. If it is necessary to perform a thorough cleaning of the filter screen 32, the connecting section 3 can be separated from the housing 1 by removing the bolt from between the insertion hole 331 and the screw hole 15, and the entire connecting section 3 can be removed for cleaning, thus facilitating the thorough cleaning of the filter screen 32.

[0036] Preferably, it also includes a second sealing ring 5 located between the mounting post 34 and the housing 1. Since the second sealing ring 5 is located between the mounting post 34 and the housing 1, it can reduce the occurrence of water flowing out from the connection position between the connecting section 3 and the housing 1, thereby improving the sealing of the connection between the connecting section 3 and the housing 1.

[0037] It is also worth noting that sealing rings can be set between multiple separate components to reduce the possibility of water flowing out of the faucet housing, rather than being limited to the first sealing ring 221 and the second sealing ring 5.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
