Description

Technical Field

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

[0002] The shower faucet has an internal filter that filters and purifies the water. Existing technology (CN202223612121.0) discloses a shower faucet with a filter that is easy to clean. The filter has a cylindrical structure and can be detachably installed on the side of the faucet body via an installation head.

[0003] Faucet housings typically contain multiple straight water channels with the water flow direction in a straight line. Due to location constraints and connection requirements, water channel bends are sometimes incorporated to change the water flow direction. Because the inlet and outlet directions of a cylindrical filter are perpendicular to each other, the cylindrical filter must be installed at the water channel bend, meaning it can only be installed in a specific location on the faucet body. For example, existing technologies disclose installations on the side of the faucet housing near a wall, which makes filter installation and removal inconvenient. Furthermore, the cylindrical structure of the removed filter makes effective cleaning difficult. Utility Model Content

[0004] One objective of this invention is to provide a filter that is installed in a straight water passage, allowing for flexible installation and easy disassembly and cleaning.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A filter is installed on a straight water passage with an inlet. The filter includes a filter screen that is inserted directly into the inlet and detachably installed on the straight water passage. The filter screen is a sheet-like structure with its surface perpendicular to the direction of water flow in the straight water passage. The filter also includes a plug that is detachably installed on the inlet to seal the inlet.

[0007] Furthermore, the filter screen includes a sheet-like filter screen and an elastic sealing frame surrounding the filter screen and deformable under compression; the elastic sealing frame has an abutting edge that abuts against the plug, and the elastic sealing frame also has two sets of sealing sides formed on both sides of the abutting edge and deforming outward under the abutting action to seal the gap between the filter screen and the straight water passage.

[0008] Furthermore, the two sets of sealing sides are semi-cylindrical structures with the arc-shaped surface facing outwards.

[0009] Furthermore, the elastic sealing frame is integrally molded onto the filter screen using silicone or plastic material.

[0010] Furthermore, the elastic sealing frame extends to form a handle, the free end of which is configured as the abutting edge that abuts against the plug.

[0011] Furthermore, grooves are formed on one or both sides of the handle.

[0012] Furthermore, the plug is a cover structure with a drive interface formed on its outer surface, and a receiving cavity is formed inside the cover structure for the insertion and reception of the handle.

[0013] Furthermore, the plug is provided with a sealing element for sealing the gap between the socket and the plug.

[0014] Another objective of this invention is to provide a shower faucet, including a faucet body, in which a straight water passage is formed, and an inlet is formed on the upper surface of the faucet body to pass through the straight water passage; a filter is installed on the straight water passage and the inlet, and the filter is located on the upper part of the faucet body.

[0015] Furthermore, the filter screen includes a sheet-like filter screen and an elastic sealing frame surrounding the filter screen and deformable under pressure; the straight water passage is provided with a slot that cooperates with the elastic sealing frame, and the slot has water passage holes formed on both sides of the slot in the water passage direction.

[0016] After adopting the above solution, the new filter adopts a combination structure of filter screen and plug, which can be directly installed in the straight water passage. During assembly, the filter screen is first inserted directly into the straight water passage from the inlet, with the screen surface perpendicular to the axial direction of the straight water passage. Then, the plug is installed on the inlet, thus completing the installation of the entire filter.

[0017] Because this new type of filter is installed in a straight water path, its placement is highly flexible and can be easily positioned on a suitable location on the top surface of a shower faucet. Users also have ample operating space and the working angle is well-suited for coordinated two-handed operation during disassembly and reassembly.

[0018] Compared with existing technologies, the installation and disassembly of this new filter are very convenient; after disassembly, simply rinse both sides of the filter screen directly, which can easily achieve effective cleaning. Attached Figure Description

[0024] Label Explanation

[0025] Faucet body 100, straight water passage 101, socket 102, slot 103, water passage hole 104;

[0026] Filter screen 1, filter screen plate 11, elastic sealing frame 12, top edge 121, sealing side 122, handle 123, groove 124, plug 2, receiving cavity 21, thread 22, seal 23, drive interface 24. Detailed Implementation

[0027] The following detailed description of this case is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figure 1-2 The diagram shown is a structural schematic of a filter used in this case. Figure 3-4 As shown, the filter is installed on the straight water passage 101, which has a straight insertion port 102 that connects to it. The corresponding insertion direction of the straight insertion port 102 is perpendicular to the straight water passage 101, and the filter is installed in a straight insertion manner through the straight insertion port 102.

[0029] The filter includes a filter screen 1 and a plug 2. The filter screen 1 is inserted directly into the straight-through inlet 102 and can be detachably installed on the straight-through water passage 101. The filter screen 1 is a sheet-like structure with its surface perpendicular to the water flow direction of the straight-through water passage 101. The plug 2 can be detachably installed on the straight-through inlet 102 to block the straight-through inlet 102.

[0030] Thus, the novel filter 1 can be directly installed on the straight water passage 101. During assembly, the filter screen 1 is first inserted directly into the straight water passage 101 through the straight connector 102, with the screen surface of the filter screen 1 perpendicular to the axial direction of the straight water passage 101. Then, the plug 2 is installed on the straight connector 102, thus completing the installation of the entire filter 1. Water flowing through the straight water passage 101 passes through the filter screen 1, achieving the effect of water filtration and purification.

[0031] Because this novel filter 1 is installed on the straight water passage 101, its placement is highly flexible in practical applications. It can be easily installed on the upper surface of the shower faucet, preferably in a suitable forward position away from the wall. During disassembly, the user has ample operating space, and the working angle is suitable for coordinated two-handed operation. Disassembly is simple: just open the plug 2 from the straight-through port 102, then insert and remove the filter screen 1 from the port 102.

[0032] Compared with the existing technology, the installation and disassembly of the new filter 1 are very convenient. After disassembly, the filter screen 1 has a sheet structure and no hidden corner areas. It is easy to achieve effective cleaning by simply rinsing both sides of the filter screen 1.

[0033] In this embodiment, the filter screen 1 includes a sheet-like filter screen 11 and an elastic sealing frame 12 surrounding the filter screen 11 and deformable under compression. The elastic sealing frame 12 has an abutting edge 121 that abuts against the plug 2 and two sets of sealing sides 122 formed on both sides of the abutting edge 121. Under the action of the plug 2 abutting against the abutting edge 121, the two sets of sealing sides 122 integrally formed with the abutting edge 121 deform outward, thereby sealing the gap between the filter screen 11 and the corresponding two sides of the straight water passage 101. The side of the elastic sealing frame 12 opposite to the abutting edge 121 is also sealed under the abutting action, so that all four sides of the filter screen 1 are sealed, thereby ensuring that the filter screen 1 performs an effective filtration effect.

[0034] Therefore, during the insertion of the filter screen 1 into the straight water passage 101, the gap between the two sets of sealing sides 122 and the straight water passage 101 allows for smooth insertion, avoiding problems such as jamming or difficulty in proper installation. Then, a plug 2 is installed on the inlet. Upon installation, the plug 2 abuts against the abutment side 121, securing the filter screen 1 and achieving a sealed assembly around the entire perimeter of the filter screen 1 through deformation caused by this abutment. Similarly, during disassembly, the plug 2 is removed first. Since the filter screen 1 is not deformed by the abutment, it can be easily removed from the straight water passage 101.

[0035] like Figure 2 As shown, the two sets of sealing sides 122 are semi-cylindrical structures with their arc-shaped surfaces facing outwards. During the abutting action, the outward deformation of the semi-cylindrical structure achieves a more significant and prominent gap sealing effect. Moreover, the arc-shaped surface of the semi-cylindrical structure also facilitates the installation and removal of the filter screen 1.

[0036] Furthermore, in this embodiment, the elastic sealing frame 12 is integrally molded onto the filter screen 11 using silicone or plastic material. When subjected to impact deformation, the connection between the filter screen 11 and the elastic sealing frame 12 remains stable.

[0037] like Figure 2 As shown, the elastic sealing frame 12 also has a handle 123, the free end of which is configured as the abutting edge 121 that abuts against the plug 2. The handle 123 extends to a position close to the insertion port 102, and the handle 123 is equivalent to the handle for installing and removing the filter screen 1, which greatly facilitates the installation and removal of the filter screen 1.

[0038] Furthermore, in this embodiment, a groove 124 is formed on one or both sides of the handle 123. The groove 124 structure makes the handle 123 form an adaptive gripping end, which is conducive to the stable gripping and holding of the handle 123 during disassembly and assembly operations, and improves the reliability of disassembly and assembly operations.

[0039] like Figure 2 As shown, the plug 2 is a cover structure with a drive interface 24 formed on its outer surface. The cover structure has a receiving cavity 21 for the handle 123 to be inserted into, thus achieving the alignment and installation of the filter screen 1 and the plug 2, as well as their effective abutting action. The outer periphery of the cover structure has threads 22, facilitating the screwing of the plug 2 onto the insertion port 102.

[0040] like Figure 1 As shown, in this embodiment, the drive interface 24 is a slot on the outer surface of the plug 2, which facilitates the insertion of a flathead screwdriver to easily install and remove the plug 2. Of course, the drive interface can also be a cross-shaped slot or other grooves of any shape.

[0041] Furthermore, the plug 2 is provided with a sealing element 23 for sealing the gap between the socket 102 and the plug 2.

[0042] This invention also provides a shower faucet, such as Figure 3-5 As shown, the device includes a faucet body 100, within which a straight water passage 101 is formed. An inlet 102, penetrating the straight water passage 101, is formed on the upper surface of the faucet body 100. A filter is installed on the straight water passage 101 and the inlet 102, and the filter is located on the upper part of the faucet body 100.

[0043] Compared to existing technologies, this new shower faucet features a filter mounted on the faucet body 100. In practice, the design allows for sufficient distance between the filter and the wall, providing ample operating space and a comfortable working angle for both hands during installation and removal. Users can simply rinse both sides of the filter screen. Therefore, disassembly, post-disassembly cleaning, and installation are all extremely convenient and easy, enhancing the user experience.

[0044] like Figure 3-4 As shown, the filter screen 1 includes a sheet-like filter screen 11 and an elastic sealing frame 12 surrounding the filter screen 11 and deformable under pressure. The straight water passage 101 is provided with a slot 103 that mates with the elastic sealing frame 12. The slot 103 has water passage holes 104 formed on its two side walls in the water passage direction. The structural cooperation between the slot 103 and the elastic sealing frame 12 facilitates the stable installation of the elastic sealing frame 12 within the straight water passage 101 and ensures a mutual sealing effect between the elastic sealing frame 12 and the straight water passage 101.
