Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a faucet with a removable filter element. Background Technology

[0002] Faucets with built-in filters are common fixtures in kitchens, bathrooms, and other similar spaces. These faucets effectively filter out impurities and harmful substances from the water, providing users with clean and safe drinking water. However, existing faucets with built-in filters present several inconveniences in terms of filter replacement.

[0003] In traditional designs, the filter cartridge is typically installed between the outlet of the base and the outlet pipe assembly. When the filter cartridge needs to be replaced, users often need to remove the outlet pipe assembly or even the entire base to access and remove the filter cartridge. This process is not only cumbersome and time-consuming, but frequent disassembly and reassembly can also cause wear and tear at the connection between the outlet and the pipe assembly, such as loosening or poor sealing, leading to safety hazards such as leaks and seepage. Utility Model Content

[0004] The purpose of this utility model is to provide a faucet with a detachable filter element, and the technical problem to be solved is to make it easier to install and remove the filter element inside the faucet.

[0005] To achieve the above objectives, the solution of this utility model is: a faucet with a detachable filter element, including a base, a water outlet assembly and a filter element. The base has an inlet, an outlet and an internal water passage connecting the inlet and the outlet. The inlet of the base is connected to a water supply device and the outlet is connected to the water outlet assembly.

[0006] The base is provided with a vertically extending installation channel, which is connected to the internal water channel of the base. The filter element is detachably installed in the installation channel. Water entering from the inlet flows through the filter element and then flows to the outlet. The installation channel has an installation port that leads to the outside of the base and avoids the inlet and outlet. The filter element enters and exits the installation channel through this installation port.

[0007] Furthermore, the mounting port of the mounting channel is provided with an end cap for opening or sealing the mounting port.

[0008] Furthermore, the end cap and the mounting port of the mounting channel are connected by thread, interference fit, or snap-fit.

[0009] Furthermore, the mounting port of the mounting channel is provided with an internal thread section, and the bottom of the end cap has an external thread section, and the two are connected by threaded screws.

[0010] Furthermore, after the filter element is placed into the installation channel, its upper end protrudes from the installation opening of the installation channel.

[0011] Furthermore, the installation channel is provided with a water inlet and a water outlet. The water inlet is located at the bottom of the installation channel, and the water outlet is located on the side of the installation channel. The installation channel is connected to the internal water passage of the base through the water inlet and the water outlet. Water from the internal water passage of the base enters the installation channel through the water inlet, is filtered by the filter element, and then flows out through the water outlet.

[0012] Furthermore, the base has a 7-shaped cross-section, with the water inlet located below the base and the water outlet located above the base. Both the water inlet and the water outlet are vertical, and their axes are parallel to each other.

[0013] Furthermore, the base is detachably connected to the water supply device and the water outlet pipe assembly.

[0014] Furthermore, the faucet body is also provided with a valve cavity for installing the valve core. The valve core is connected to a switch handle. By driving the valve core through the switch handle, the on / off control of the faucet water circuit, the control of the water flow rate, and the control of the water temperature can be realized.

[0015] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0016] The base of this invention is provided with an installation channel for installing the filter element. The installation channel is connected to the internal water passage of the base, and the installation channel has an installation port leading to the outside of the base. Users can quickly remove and place the filter element through this installation port to replace or maintain the filter element.

[0017] Furthermore, the installation port in this solution is designed to avoid the positions of the inlet and outlet on the base, and does not interfere with either. Compared to traditional faucets where the water pipe assembly, base, and other components need to be removed when changing the filter cartridge, this solution only requires opening the installation port on the base to remove and insert the filter cartridge. This design is not only simple and convenient to operate, but also avoids the wear and tear at the outlet caused by frequent disassembly and assembly of the water pipe and other components, reducing the risk of leaks and seepage.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This utility model provides a faucet with a detachable filter element, such as... Figures 1 to 5 As shown, the device includes a base 1, a water outlet pipe assembly 2, and a filter element 3. The base 1 has a water inlet 11, a water outlet 12, and an internal water passage connecting the inlet 11 and the outlet 12. The water inlet 11 of the base 1 is connected to a water supply device, and the water outlet 12 is connected to the water outlet pipe assembly 2. When the water supply device supplies water to the faucet, water flows into the interior of the base 1 through the water inlet 11, then exits through the water outlet 12, flows to the water outlet pipe assembly 2, and finally sprays out from the water outlet pipe assembly 2, providing users with a clean and safe water experience.

[0028] In this embodiment, as Figure 2 As shown, the cross-section of the base 1 is shaped like the number 7. The water inlet 11 is located below the base 1, and the water outlet 12 is located above the base 1, which conforms to the installation position of a conventional water supply device and water outlet pipe assembly 2. Both the water inlet 11 and the water outlet 12 are kept in a vertical direction, and their axes are parallel to each other.

[0029] The base 1 has an installation channel 13, and the filter element 3 is detachably installed in the installation channel 13 to filter the water flowing through it. Specifically: Figure 2 As shown, the installation channel 13 is vertically mounted on the base 1 and located above the water inlet 11. The installation channel 13 is connected to the internal water system of the base 1. The installation channel 13 has an inlet hole 132 and an outlet hole 133. The inlet hole 132 is located at the bottom of the installation channel 13, and the outlet hole 133 is located on the side of the installation channel 13. Water from the internal water system of the base 1 enters the installation channel 13 through the inlet hole 132, is filtered by the filter element 3, and then flows out through the outlet hole 133.

[0030] The installation channel 13 has a mounting port 131 leading to the outside of the base 1, through which the user can remove or install the filter element 3 for replacement or maintenance. Furthermore, as... Figure 3 and Figure 4As shown, the mounting port 131 is positioned to avoid the water inlet 11 and water outlet 12 of the base 1, giving the filter element 3 an independent inlet and outlet. This eliminates the need to pass through the water inlet 11 or water outlet 12 when installing or removing the filter element 3. After the filter element 3 is placed in the mounting channel 13, its upper end protrudes from the mounting port 131 of the mounting channel 13. The protruding part is easy for the user to grasp, thus eliminating the need for additional tools to grasp the filter element 131 located within the mounting channel 13.

[0031] like Figure 1 and Figure 2 As shown, this design adds an end cap 4 to the mounting port 131 of the mounting channel 13. The end cap 4 is used to open or seal the mounting port 131. The connection methods between the end cap 4 and the mounting port 131 include, but are not limited to, threaded connection, plug-in connection, and snap-fit ​​connection. In this embodiment, the mounting port 131 of the mounting channel 13 has an internal thread section, and the bottom of the end cap 4 has an external thread section; the two are connected by threads. After the end cap 4 is tightened, the end cap 4 and the bottom of the mounting channel 13 press against both ends of the filter element 3, avoiding problems such as unstable water flow and reduced filtration effect caused by shaking.

[0032] When filter element 3 needs to be replaced, the user simply unscrews end cap 4 to remove or insert the new filter element 3. After replacement, the end cap 4 is screwed back onto mounting port 131 to easily achieve an airtight seal. Since mounting port 131 is independent of inlet 11 and outlet 12, it is not necessary to disassemble the components connected to inlet 11 and outlet 12 when removing filter element 3. This design not only makes the installation and removal of filter element 3 more convenient but also effectively avoids wear and tear at the interfaces caused by frequent disassembly of other components.

[0033] When water purification is not required here, the filter element 3 in the installation channel 13 can be removed and the end cap 4 can be tightened. At this time, the installation channel 13 is just an ordinary water passage chamber and will not affect the normal flow of water.

[0034] The filter element 3 described in this utility model is existing technology. It contains multiple layers of filter media, which can effectively remove impurities, residual chlorine, heavy metals and other harmful substances from the water, thereby improving water quality. Given that the structure and filtration principle of filter element 3 are widely known in the industry, its details will not be elaborated here. Users can choose the appropriate type of filter element 3 according to local water quality, the health status of family members or personal preferences.

[0035] The control components of this faucet have the following specific structure: Figure 1 and Figure 3As shown, the base 1 has a valve chamber 14 for mounting the valve core 5. The valve core 5, as the core component for controlling the faucet function, is connected to a switch handle 6, allowing the user to drive the valve core 5 by turning the switch handle 6, thereby realizing the on / off control of the water circuit of the base 1, fine adjustment of the water flow, and free switching between hot and cold water.

[0036] The water flow inside the base 1 of this faucet is as follows: Figure 3 and Figure 4 As shown, external water enters the interior of the base 1 through the inlet 11, enters the installation channel 13 through the inlet 132, is filtered by the filter element 3, and then flows out through the outlet 133, flows through the outlet 12 of the base 1 to the outlet pipe assembly 2, and is finally supplied to the user.

[0037] As a further improvement to the structure, the base 1 is detachably connected to both the water supply device and the water outlet pipe assembly 2. This means that the base 1 can be removed as an independent unit, providing greater flexibility. Specific connection methods include, but are not limited to, threaded connections, interference fits, and snap-fit ​​connections, as long as they ensure the stability of the base 1 during installation and the ease of disassembly.

[0038] It should be noted that the faucet structure applicable to the base 1 of this utility model is not limited to that shown in the embodiments and drawings of this utility model. It can also be a common non-pull-out faucet (see reference). Figure 5 ), pull-out faucets, etc.

[0039] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components. Furthermore, the front, back, left, and right directions involved in this embodiment are only as a reference and do not represent the actual orientation in practical application.

[0040] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
