Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to a kitchen faucet with a pull-out function to prevent clogging. Background Technology

[0002] In kitchen water usage scenarios, faucets are indispensable equipment. However, traditional kitchen faucets have many problems in actual use.

[0003] On the one hand, water quality issues are becoming increasingly prominent, with water often containing various impurities such as sediment, rust, and particulate matter. Traditional faucets lack effective filtration devices, allowing these impurities to enter the faucet with the water flow. Over time, these impurities tend to accumulate inside the faucet, leading to blockages. Once a faucet is blocked, the water flow will decrease or even cease, severely impacting kitchen water efficiency and causing significant inconvenience in daily life. Moreover, cleaning the inside of a blocked faucet is extremely difficult, usually requiring disassembly. This not only demands specialized tools and skills but also carries the risk of damaging the faucet due to improper handling, increasing repair costs.

[0004] On the other hand, traditional faucets have a relatively simple structural design and limited functionality. Cleaning the inside of a faucet often requires disassembling the entire faucet, a cumbersome and time-consuming process. This is especially true for concealed faucets, where disassembly and installation are even more complex, causing significant inconvenience for users. Furthermore, the connections between components in traditional faucets are not always secure during installation and disassembly, making them prone to loosening and leaks. This not only wastes water but can also potentially damage the kitchen environment.

[0005] Therefore, developing a kitchen faucet with efficient filtration, easy cleaning and maintenance, and flexible installation and disassembly is of great practical significance in order to meet people's high requirements for kitchen water equipment and improve the quality and convenience of kitchen water. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of effective filtration devices in traditional faucets, their relatively simple structural design, and limited functionality. Cleaning the inside of a traditional faucet often requires disassembling the entire faucet, which is cumbersome, time-consuming, and laborious. Therefore, this invention proposes a kitchen faucet with a pull-out function to prevent clogging.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A kitchen faucet with a pull-out function and anti-clogging feature, comprising a faucet body;

[0009] The filter head is detachably connected to one end of the faucet body;

[0010] The nozzle is fixedly embedded at the other end of the filter head;

[0011] A pull-out box is slidably embedded in one side of the filter head;

[0012] A secondary filtration assembly is disposed inside the pull-out box;

[0013] A braking assembly is disposed on one side of the filter head;

[0014] The water is filtered once by the nozzle and then filtered a second time by the secondary filtration assembly, which effectively prevents the faucet from getting clogged.

[0015] In one possible design, the secondary filtering component includes:

[0016] Multiple filter holes are formed on the outer wall of the pull-out box;

[0017] A side cover is inserted into the top opening of the pull-out box;

[0018] Strip-shaped protrusions are fixedly installed on the inner walls of both sides of the opening;

[0019] A strip-shaped groove is formed on the inner walls of both sides of the side cover plate, and the strip-shaped groove is slidably fitted onto the strip-shaped protrusion.

[0020] One possible design also includes:

[0021] A water inlet pipe is installed inside the pull-out box;

[0022] A rectangular plate is fixedly sleeved on the bottom of the outer wall of the water inlet pipe;

[0023] Multiple limiting rods are fixedly installed on the top of the rectangular plate;

[0024] A round hole is formed inside the side cover plate, and the round hole is used in conjunction with the water inlet pipe;

[0025] Multiple first limiting holes are formed inside the strip-shaped protrusion;

[0026] Multiple second limiting holes are formed inside the strip-shaped groove;

[0027] The limiting rod cooperates with the first limiting hole and the second limiting hole to fix the lateral cover plate.

[0028] In one possible design, the braking assembly includes:

[0029] A fixing screw is threaded onto one side of the filter head;

[0030] A threaded groove is formed on one side of the water inlet pipe, and the fixing screw is threadedly connected to the threaded groove;

[0031] When the fixing screw is screwed in, the water inlet pipe is braked.

[0032] In one possible design, it also includes: multiple rubber rings, which are fixedly sleeved on the outer wall of the water inlet pipe;

[0033] The rubber ring provides a seal at the connection point to prevent water leakage.

[0034] In one possible design, the filter head is detachably connected to the faucet body via an external thread.

[0035] In one possible design, the top opening of the pull-out box is flush with the bottom of the side cover, allowing the pull-out box to be pulled out as a whole.

[0036] In one possible design, the diameter of the circular hole matches the outer diameter of the water inlet pipe to ensure a secure fit.

[0037] In this application, during use, the faucet body is installed on the kitchen water inlet pipe, and the water flow is controlled by the spray head. The water enters the interior of the filter head through the faucet body, and enters the interior of the pull-out box along the water inlet pipe. After being filtered through the filter holes, it is discharged. A small amount of water is discharged through the gap between the water inlet pipe and the filter head, and finally it is filtered again by the spray head before being discharged.

[0038] When it is necessary to clean the impurities inside the pull-out box, you can first unscrew the fixing screws. At this time, the fixing screws are no longer connected to the threaded groove, releasing the braking state of the water inlet pipe. At this time, the water inlet pipe moves down under the action of gravity and retracts into the inside of the pull-out box. The top of the water inlet pipe is flush with the bottom of the side cover plate. Pull out the entire pull-out box.

[0039] At this point, since the limiting rod is no longer stuck inside the second limiting hole and the first limiting hole, the braking state of the side cover can be released, the side cover can be pulled out laterally, the strip protrusion slides inside the strip groove, the water inlet pipe can be taken out, and the inside of the pull-out box can also be cleaned.

[0040] When the device needs to be installed, the filter head needs to be unscrewed. Then, invert the filter head and insert the water inlet pipe into the pull-out box. Insert the side cover plate. At this time, one end of the water inlet pipe will be stuck into the round hole under the action of gravity. After inserting the pull-out box inverted, the water inlet pipe will continue to move down under the action of gravity and engage with the water inlet end of the filter head. The limiting rod will enter the first limiting hole and the second limiting hole to fix the device again. Screw in the fixing screw to fix the water inlet pipe again. Then, turn the filter head back to the normal position and use the external thread to screw the filter head into the faucet body.

[0041] Beneficial effects: This faucet uses a spray nozzle for primary filtration, and a secondary filtration component is installed in the pull-out box. Water passes through the spray nozzle and pull-out box and is further filtered through the filter holes, which can effectively intercept impurities in the water, greatly reduce the risk of faucet clogging, extend the faucet's service life, and reduce maintenance and replacement costs caused by clogging.

[0042] Cleaning the inside of the pull-out drawer is simple. Just unscrew the fixing screws to release the water inlet pipe's brake; the pipe will retract under gravity until the top of the drawer is flush with the bottom of the side cover, allowing you to pull the entire drawer out. Then, release the side cover's brake and pull it out horizontally to remove the water inlet pipe and thoroughly clean the inside of the drawer. No complicated tools or professional personnel are needed, saving time and effort.

[0043] When installing the device, first unscrew the filter head and invert it, insert it into the inlet pipe, and then insert the side cover plate. Use gravity to make the inlet pipe lock into the round hole and engage with the inlet end of the filter head. At the same time, the limiting rod enters the corresponding limiting hole to secure it. Finally, screw in the fixing screw and screw the filter head back in. The entire installation process is simple and easy to understand, allowing users to operate it themselves. The disassembly process is equally easy, facilitating the inspection or replacement of various parts of the faucet.

[0044] The water inlet pipe and side cover are double-fixed by the threaded connection of the fixing screw and the threaded groove, as well as the cooperation of the limiting rod with the first limiting hole and the second limiting hole. This ensures that the position of each component is stable during normal use and will not loosen due to water flow impact or daily use, thus ensuring the normal operation of the faucet and the filtration effect.

[0045] Multiple rubber rings are fixedly fitted on the outer wall of the water inlet pipe. When the water inlet pipe is connected to the filter head component, the rubber rings can play a good sealing role, preventing water from leaking from the connection, avoiding water waste and a humid kitchen environment, and improving the safety and comfort of use.

Detailed Implementation

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0052] In one embodiment: Refer to Figure 1-4 A specific implementation method of a faucet:

[0053] This kitchen faucet with a pull-out function and anti-clogging feature is mainly composed of the faucet body 1, filter head 2, spray head 3, pull-out box 4, fixing screws 5, water inlet pipe 8, and side cover plate 9.

[0054] The faucet body 1 is installed on the water inlet pipe in the kitchen, and one end of it is detachably connected to the filter head 2 via an external thread 6. The other end of the filter head 2 is fixedly embedded with a spray nozzle 3, which has fine holes distributed on it. When water flows through it, it can filter the water once, intercepting larger particles of impurities in the water, such as mud, sand, and rust.

[0055] A pull-out box 4 is slidably embedded on one side of the filter head 2, and a secondary filtration assembly is installed inside the pull-out box 4. The secondary filtration assembly includes multiple filter holes 10 formed on the outer wall of the pull-out box 4. These filter holes 10 are evenly distributed and can perform secondary filtration on the water entering the pull-out box 4, further intercepting tiny impurities in the water. The top of the pull-out box 4 is open, and strip-shaped protrusions 11 are fixedly installed on the inner walls of both sides of the opening. A side cover plate 9 is inserted into the opening. Strip-shaped grooves 16 are formed on the inner walls of both sides of the side cover plate 9. During installation, the strip-shaped grooves 16 are slidably fitted onto the strip-shaped protrusions 11, so that the side cover plate 9 can be stably installed on the pull-out box 4, while facilitating subsequent disassembly and cleaning.

[0056] The secondary filtration assembly also includes an inlet pipe 8, with a rectangular plate 18 fixedly fitted onto the bottom of its outer wall. Multiple limiting rods 17 are fixedly installed on the top of the rectangular plate 18. A circular hole 14 is formed inside the side cover plate 9, the diameter of which matches the outer diameter of the inlet pipe 8, allowing the inlet pipe 8 to engage with the circular hole 14. Multiple second limiting holes 15 are formed inside the strip-shaped groove 16, and multiple first limiting holes 12 are formed inside the strip-shaped protrusion 11. The limiting rods 17 can engage with the second limiting holes 15 and the first limiting holes 12 to fix the side cover plate 9 and the inlet pipe 8.

[0057] Multiple rubber rings 7 are fixedly fitted on the outer wall of the water inlet pipe 8. The rubber rings 7 have good elasticity and sealing performance. When the water inlet pipe 8 is connected to the filter head 2, the rubber rings 7 can fill the gap at the connection and prevent water from leaking out. A threaded groove 13 is opened on one side of the water inlet pipe 8 for mating with the braking assembly.

[0058] This application can be used in the field of kitchenware, or in other fields applicable to this application.

[0059] In another embodiment: Reference Figure 1-4 A kitchen faucet with a pull-out function and anti-clogging design is used in the field of kitchen appliances. The braking component includes a fixing screw 5 threaded through one side of the filter head 2, and the fixing screw 5 is threadedly connected to the threaded groove 13. When the fixing screw 5 is screwed into the threaded groove 13, it can brake the water inlet pipe 8 and fix its position; when it is necessary to release the brake, the fixing screw 5 can be unscrewed.

[0060] When using this faucet, water enters the interior of the filter head 2 through the faucet body 1, and then enters the interior of the pull-out box 4 along the inlet pipe 8. Most of the water is filtered through the filter hole 10 and discharged, while a small amount of water is discharged through the gap between the inlet pipe 8 and the filter head 2. Finally, the water is filtered again through the nozzle 3 before being discharged, thus achieving double filtration of the water, effectively intercepting impurities in the water and preventing the faucet from clogging.

[0061] When it is necessary to clean the impurities inside the pull-out box 4, first unscrew the fixing screw 5 so that it is no longer threaded into the threaded groove 13, thus releasing the braking state of the water inlet pipe 8. At this time, the water inlet pipe 8 moves down under the action of gravity and retracts into the interior of the pull-out box 4 until the top of the water inlet pipe 8 is flush with the bottom of the side cover plate 9. Then, pull out the pull-out box 4 as a whole. Since the limiting rod 17 is no longer stuck inside the second limiting hole 15 and the first limiting hole 12, the braking state of the side cover plate 9 is released. At this time, the side cover plate 9 can be pulled out laterally. During the pulling process, the strip protrusion 11 slides inside the strip groove 16 to ensure the stability of the side cover plate 9 during pulling out. Finally, remove the water inlet pipe 8 and thoroughly clean the interior of the pull-out box 4 to remove accumulated impurities.

[0062] When the cleaning is complete and the device needs to be installed, first unscrew the filter head 2 and invert it. Insert the water inlet pipe 8 into the pull-out box 4, and then insert the side cover plate 9. At this point, one end of the water inlet pipe 8 will be engaged with the round hole 14 under gravity, achieving initial positioning of the water inlet pipe 8 and the side cover plate 9. Next, invert the pull-out box 4 and insert it. The water inlet pipe 8 will continue to move downwards under gravity, engaging with the water inlet end of the filter head 2. Simultaneously, the limiting rod 17 will enter the first limiting hole 12 and the second limiting hole 15, further securing the device and ensuring the stability of the connection between components. Then, screw in the fixing screw 5 to secure the water inlet pipe 8 again, preventing it from moving during use. Finally, return the filter head 2 to its normal position and screw it into the faucet body 1 using the external thread 6, completing the installation of the entire device.

[0063] This kitchen faucet with a pull-out function effectively intercepts impurities in the water through primary and secondary filtration components, preventing clogging and improving water efficiency in the kitchen. Its unique structural design also makes cleaning and maintenance quick and easy, eliminating the need to disassemble the entire faucet, saving time and effort. Furthermore, the braking component and limit structure ensure a stable connection between all parts, preventing leaks and enhancing safety and reliability.

[0064] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
