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] In existing faucets with built-in filters, the filter is usually installed in a concealed location, between the spout and the water supply assembly in the base. When the filter needs to be replaced, the user must first remove the water supply assembly or even the entire base to access and replace the filter. This process is not only cumbersome, time-consuming, and laborious, increasing the difficulty for users, but frequent disassembly and reassembly may also cause unnecessary wear and tear on the connection between the spout and the water supply assembly, leading to loosening, poor sealing, and potentially causing safety hazards such as leaks and seepage. Utility Model Content

[0003] The purpose of this utility model is to provide a faucet with a detachable filter element, which makes the filter element easier to install and remove, reduces unnecessary disassembly of other parts, and reduces wear and tear.

[0004] To achieve the above objectives, the solution of this utility model is as follows: a faucet with a detachable filter element, comprising a base, a water outlet assembly and a filter element, wherein the base has a water inlet, a water outlet and an internal water passage connecting the water inlet and the water outlet, the water inlet of the base is connected to a water supply device, and the water outlet is connected to the water inlet end of the water outlet assembly.

[0005] The base is provided with an installation channel that extends laterally on the base and is connected to the internal water channel of the base. The filter element is detachably installed in the installation channel. Water entering the base from the inlet flows through the filter element and then flows to the outlet.

[0006] The outer surface of the base has a side opening leading to the installation channel, through which the filter element enters and exits the installation channel.

[0007] Furthermore, the lateral opening of the mounting channel is sealed by a removable end cap.

[0008] Furthermore, the end cap is connected to the lateral opening of the mounting channel by means of threads, plugs, or snaps.

[0009] Furthermore, the lateral opening is provided with a first threaded section, and the bottom of the end cap has a second threaded section corresponding to the first threaded section. The end cap and the lateral opening are connected by the cooperation of these two threaded sections.

[0010] Furthermore, after the filter element is installed in the installation channel, its inner end abuts against the bottom of the installation channel, and its outer end protrudes from the lateral opening.

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

[0012] Furthermore, the water inlet is located below the base, and the water outlet is located above the base. Both the water inlet and the water outlet are vertical, and their axes are parallel to each other. The axis of the installation channel is perpendicular to the axes of the water inlet and the water outlet.

[0013] Furthermore, the base is detachably connected to both the water supply equipment and the water outlet 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 utility model 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 surface of the base has a side opening leading to the installation channel. Users can quickly remove and place the filter element through this side opening to replace or maintain it. Furthermore, this side opening is designed to avoid the positions of the water inlet and outlet on the base, and does not interfere with them. Compared to traditional faucets where the water outlet assembly and base need to be removed when replacing the filter element, this solution only requires opening the side opening on the base to remove and place the filter element. This design is not only simple and convenient to operate, but also avoids the wear and tear at the water outlet caused by frequent disassembly and assembly of water pipes 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 removable filter element, such as... Figures 1 to 6 As shown, the device includes a base 1, a water outlet assembly 2, and a filter element 3. The base 1 has an inlet 11, an outlet 12, and an internal water passage connecting the inlet 11 and the outlet 12. The inlet 11 on the base 1 is used to connect to a water supply device, while the outlet 12 is used to connect to the water outlet assembly 2. When the water supply device supplies water to the faucet, water flows into the base 1 through the inlet 11, then exits through the outlet 12, flows to the water outlet assembly 2, and finally sprays out from the water outlet assembly 2 to provide water to the user.

[0028] In this embodiment, as Figure 2 and Figure 3 As shown, the water inlet 11 of the base 1 is located below the base 1, and the water outlet 12 is located above the base 1. This layout conforms to the installation position of conventional water supply equipment and water outlet 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 3 As shown, the installation channel 13 is horizontally arranged on the base 1, meaning that the axis of the installation channel 13 extends horizontally and is perpendicular to the axes of the inlet 11 and the outlet 12. The installation channel 13 is connected to the internal water passage 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 passage 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] like Figure 3 As shown, the base 1 has a side opening 131 leading to the mounting channel 13, through which the user can remove or install the filter element 3 for replacement or maintenance. Furthermore, as... Figure 2 and Figure 3 As shown, the side opening 131 is positioned to avoid the inlet 11 and outlet 12 of the base 1, giving the filter element 3 an independent inlet and outlet. This eliminates the need to pass through the inlet 11 or outlet 12 when installing or removing the filter element 3. After the filter element 3 is placed in the installation channel 13, its inner end abuts against the bottom of the installation channel 13, while its outer end protrudes from the side opening 131. The protruding part is easy for the user to grasp, thus eliminating the need for additional tools to handle the filter element 131 within the installation channel 13.

[0031] like Figures 1 to 3 As shown, this design adds an end cap 4 to the side opening 131, which is used to open or seal the side opening 131. The connection methods between the end cap 4 and the side opening 131 include, but are not limited to, threaded connection, plug-in (interference fit), and snap-fit ​​connection. In this embodiment, the side opening 131 of the mounting channel 13 is provided with a first threaded section, and the bottom of the end cap 4 is provided with a second threaded section. The two are connected by the cooperation of these two threaded sections. 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 weakened 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 tightened onto the side opening 131 to easily achieve an airtight seal. Since the side opening 131 is independent of the inlet 11 and outlet 12, the components connected to the inlet 11 and outlet 12 do not need to be disassembled 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. When water purification is not required, filter element 3 can be removed from the installation channel 13, and end cap 4 can be tightened. At this time, the installation channel 13 is a normal water passage chamber and will not affect the normal flow of water.

[0033] 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.

[0034] The control components of this faucet have the following specific structure: Figures 3 to 5 As shown, the base 1 has a valve chamber 14 for mounting the valve core 5. The valve chamber 14 and the mounting channel 13 are located at the left and right ends of the base, respectively. The valve core 5 is the core component for controlling the faucet function. It is connected to a handle switch 6, so that the user can 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, the fine adjustment of the water flow, and the free switching between hot and cold water.

[0035] The water flow inside the base 1 of this faucet is as follows: Figure 6 As shown, external water enters the interior of the base 1 through the inlet 11, 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, flows through the outlet 12 of the base 1 to the water outlet assembly 2, and is finally supplied to the user.

[0036] As a further improvement to the structure, the base 1 is detachably connected to both the water supply equipment and the water outlet assembly 2. (Refer to...) Figure 2 That is, 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 the stability of base 1 during installation and the ease of disassembly are ensured.

[0037] It should be noted that the faucet structure applicable to the base 1 of this utility model is not limited to the embodiments and figures shown in this utility model, but can also be a common non-pull-out faucet, a pull-out faucet, etc.

[0038] 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.

[0039] 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.
