Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a faucet with a replaceable filter cartridge. Background Technology

[0002] A faucet is a common term for a water valve, used to control the flow of water and thus saving water. A filter cartridge is a professional term for a device that filters and purifies water, used to purify raw fluids and separate them from other fluids. A faucet with an easily replaceable filter cartridge refers to a faucet designed to facilitate filter cartridge replacement for users. For example, the faucet with announcement number CN222669077U features an easily replaceable filter cartridge inside the faucet. This cartridge filters impurities from tap water. The valve is located on one side of the faucet, while the filter cartridge is independently mounted. A stabilizing cap and a sealing plug are installed above the filter cartridge. After installation, the sealing plug seals the filter cartridge's installation location, and the stabilizing cap allows for direct removal of the filter cartridge.

[0003] While the aforementioned technology allows for direct removal of the filter cartridge through the installation of a secure cover, it has the drawback of not being able to clean the filter cartridge without disassembling it. As the usage time increases, the filter cartridge will continuously trap impurities in the water. If it is not cleaned in time, these impurities will accumulate and cause the filter cartridge pores to become clogged. However, each time the filter cartridge is cleaned, it needs to be disassembled, which reduces the convenience of use. Furthermore, during the process of disassembling and installing the filter cartridge, it will be exposed to the air and easily become contaminated by dust. Utility Model Content

[0004] The purpose of this utility model is to provide a faucet with a conveniently replaceable filter element, in order to solve the problem mentioned in the background art that current faucets on the market cannot clean the filter element without disassembling them.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a faucet with easily replaceable filter cartridge, comprising a hollow tube, an inlet pipe inside the hollow tube, and an outlet pipe at one end of the hollow tube; a T-shaped tube at one end of the hollow tube, one end of which is connected to the inlet pipe; a first valve installed at the top of the T-shaped tube, a second valve installed at the bottom of the T-shaped tube; a first drain pipe at the upper part of the T-shaped tube, and a second drain pipe at the lower part of the T-shaped tube, with one end of the first drain pipe and the second drain pipe connected to a hollow cylinder; a filter cartridge inside the hollow cylinder; a third drain pipe connected between the top end of the filter cartridge and the hollow tube; a cylinder cover at the bottom of the hollow cylinder; a limiting component for limiting the position of the cylinder cover on the hollow cylinder; and a pressing component for pressing the filter cartridge at the bottom of the cylinder cover.

[0006] Preferably, the limiting component includes four limiting posts disposed around the hollow cylinder, and L-shaped grooves are provided around the cylinder cover.

[0023] 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.

[0024] This utility model provides the following technical solution: a faucet with an easily replaceable filter cartridge:

[0025] Example 1: The T-shaped pipe 4, the first drain pipe 7, and the second drain pipe 8 can be used to change the filtration direction of the filter element 10, such as... Figures 1-6As shown, the device includes a hollow tube 1, an inlet pipe 2 inside the hollow tube 1, an outlet pipe 3 at one end of the hollow tube 1, a T-shaped pipe 4 at one end of the hollow tube 1, one end of the T-shaped pipe 4 being connected to the inlet pipe 2, a first valve 5 installed at the top of the T-shaped pipe 4, a second valve 6 installed at the bottom of the T-shaped pipe 4, a first drain pipe 7 at the upper part of the T-shaped pipe 4, and a second drain pipe 8 at the lower part of the T-shaped pipe 4. Both the first drain pipe 7 and the second drain pipe 8 are connected to a hollow cylinder 9. The hollow cylinder 9 is equipped with a filter element 10 inside. A third drain pipe 11 is connected between the top end of the filter element 10 and the hollow tube 1. The bottom of the hollow cylinder 9 is equipped with a cylinder cover 12. A third valve 18 is provided at one end of the third drain pipe 11. A first sealing ring is provided between the top of the filter element 10 and the top of the inner cavity of the hollow cylinder 9. A second sealing ring is provided between the cylinder cover 12 and the hollow cylinder 9. A base is installed at the bottom of the hollow tube 1. A valve core is provided at the top of the hollow tube 1. A rotary switch connected to the valve core is installed at the top of the hollow tube 1.

[0026] When water enters through the inlet pipe 2, the first valve 5 can be closed and the second valve 6 can be opened, allowing water to pass through the T-shaped pipe 4 and enter the hollow cylinder 9 through the second drain pipe 8. Then, the filter element 10 filters the water, and the filtered water enters the hollow cylinder 1 through the third drain pipe 11 and is then discharged through the outlet pipe 3. When it is necessary to clean the filter element 10, the first valve 5 can be opened, the second valve 6 can be closed, and the third valve 18 can be closed, allowing water to pass through the T-shaped pipe 4 and enter the hollow cylinder 9 through the first drain pipe 7, thereby backwashing the filter element 10. The cylinder cover 12 can limit and fix the filter element 10 during rinsing, so that the rinsed water can be discharged from the bottom of the filter element 10.

[0027] Example 2: Unlike Example 1, the limiting component can limit the position of the filter element 10, such as... Figures 4-6 As shown, the hollow cylinder 9 is provided with a limiting component for limiting the cylinder cover 12. The limiting component includes four limiting pins 13 disposed around the hollow cylinder 9. The cylinder cover 12 is provided with L-shaped grooves around its perimeter, and the four limiting pins 13 are slidably connected to the four L-shaped grooves. The upper and lower perimeters of the cylinder cover 12 are provided with storage grooves, and each of the eight storage grooves is slidably connected with a protrusion 14. A spring is provided between each of the eight protrusions 14 and the eight storage grooves. The diameter of the end of the four limiting pins 13 near the hollow cylinder 9 is smaller than the diameter of the end away from the hollow cylinder 9, and the ends of the eight protrusions 14 that are close to each other are all arc-shaped.

[0028] When the filter element 10 needs to be replaced, the cover 12 can be rotated to make the protrusion 14 rotate and contact the limiting post 13, thereby causing the protrusion 14 to slide in the receiving groove. When the limiting post 13 moves away from the protrusion 14, the cover 12 can be moved downwards to make the limiting post 13 contact the vertical part of the L-shaped groove, thereby moving the limiting post 13 away from the L-shaped groove, thus completing the removal of the cover 12. Then the filter element 10 can be replaced. When the filter element 10 needs to be fixed, the L-shaped groove and the limiting post 13 can be aligned, and then the cover 12 can be pushed upwards. After moving to the appropriate position, the cover 12 can be rotated again to make the protrusion 14 contact the limiting post 13. After the limiting post 13 moves to the appropriate position, the protrusion 14 then limits the limiting post 13.

[0029] Example 3: Unlike Example 2, the clamping assembly can clamp the filter element 10, such as... Figure 3 and Figure 4 As shown, the bottom of the cylinder cover 12 is provided with a pressing assembly for pressing the filter element 10. The pressing assembly includes a pressing column 15 movably connected inside the cylinder cover 12. The bottom of the cylinder cover 12 is provided with an L-shaped plate 16. A row of limiting plates 17 is provided on one side of the pressing column 15, and the limiting plates 17 and the L-shaped plate 16 are slidably connected. The row of limiting plates 17 are equidistantly distributed, and the spacing between the limiting plates 17 is the same as the thickness of the L-shaped plate 16. A second sealing ring is provided at the connection between the pressing column 15 and the cylinder cover 12, and a rotating ring is provided at the bottom of the pressing column 15.

[0030] When it is necessary to press the filter element 10, the pressing column 15 can be inserted into the inside of the cylinder cover 12 and contact the filter element 10. Then, the pressing column 15 is moved upward. After it is moved to the appropriate position, the rotating ring is rotated to make the pressing column 15 rotate, so that the L-shaped plate 16 reaches between the limiting plate 17, thereby limiting the pressing column 15.

[0031] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
