Description

Technical Field

[0001] This utility model relates to the field of water purifier filter cartridge installation technology, specifically a filter cartridge installation structure. Background Technology

[0002] Rotary filter cartridges are widely used in water purifiers, water dispensers and other equipment. They are fixed to the main body of the equipment by screwing together with a threaded structure. The filter cartridge and the main body are sealed by a rubber sealing ring. Some products will apply silicone oil to the surface of the sealing ring to reduce frictional resistance during screwing and to assist in installation.

[0003] However, the traditional rotary filter cartridge installation structure still has certain technical defects. Specifically, the silicone oil will gradually evaporate or be washed away by water flow over time, resulting in a significant increase in the frictional resistance between the sealing ring and the inner wall of the main body (such as scale and colloids). It will mix with the dried silicone oil, causing the filter cartridge to "stick" to the main body. Users need to use tools such as wrenches and pliers to disassemble it, which is not only inconvenient to operate, but also easy to damage the threaded structure of the filter cartridge or the main body of the equipment. Therefore, a filter cartridge installation structure is needed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a filter element installation structure to solve the problem mentioned in the background art that many rotary filter elements are usually impossible to unscrew due to the frictional resistance of the rubber ring. Over time, the silicone oil of many filter elements will dissipate and stick directly to the gap of the tightly screwed filter element, requiring the use of tools to open it.

[0005] This utility model provides the following technical solution: a filter element installation structure, including a fixing mechanism, wherein the fixing mechanism includes a track extending toward the filter element installation position and opened on the housing; And baffles that obstruct the installation position of the filter element; The baffle is connected to several sliders that slide in the track; It also includes a positioning mechanism, which is located at the point where the filter element and the housing are opposite each other.

[0006] To achieve the above technical solution, a baffle slides in the track. The baffle can block the installation position of the filter element, thereby quickly completing the installation limit of the filter element. Compared with the existing technology, this device removes the filter element by pushing the baffle and then pulling it out. The overall operation process is simpler and less likely to damage the interface position.

[0007] As a further improvement to this utility model, the track is vertical, and there are two of them, which are symmetrical along the installation position of the filter element.

[0008] The above technical solution ensures the stability and guidance of the baffle movement.

[0009] As a further improvement to this utility model, the outer side of the track extends to form a enclosure for placing the baffle.

[0010] Implementing the above technical solution facilitates additional limiting of the baffle when it is in an obstructed state.

[0011] As a further improvement to this utility model, a number of protrusions are evenly connected on the inner wall of the track, and a number of stop frames that are engaged with the protrusions are connected on the baffle.

[0012] The above technical solution facilitates the positioning of the baffle at several points in the track.

[0013] As a further improvement to this utility model, the protrusion facing the movable side of the stop frame is designed with an inclined surface, and the end of the stop frame is L-shaped and hooked to the edge of the track.

[0014] The above technical solution improves the stability and guidance of the gear shifter's movement in the track.

[0015] As a further improvement to this utility model, the baffle is located at the bottom of the track travel, which obstructs the installation position of the filter element.

[0016] The above technical solution makes the baffle less prone to accidental slippage.

[0017] As a further improvement to this utility model, the slider is provided with a screw hole, and a screw that forms a stop with the edge of the track is screwed into the screw hole.

[0018] The above technical solution facilitates the removal, replacement, and maintenance of the baffle from the track.

[0019] As a further improvement to this utility model, the positioning mechanism includes a plurality of extrusion strips connected to the filter element and in close contact with the baffle in the shielding state, and the extrusion strips are designed with an arc surface facing the direction of movement of the baffle.

[0020] The above technical solution improves the squeezing effect of the baffle on the filter element.

[0021] As a further improvement to this utility model, the positioning mechanism also includes an open positioning rail at the location of the housing pipeline, and a positioning strip connected to the filter element slides into the positioning rail.

[0022] The above technical solution facilitates precise alignment between the filter element and the pipeline.

[0023] As a further improvement to this utility model, the opening of the positioning rail is designed as a flared mouth.

[0024] The above technical solution facilitates the insertion of the positioning strip into the positioning rail.

[0025] The technical effects and advantages of this utility model are as follows: This utility model uses a baffle that slides in the track. The baffle can block the installation position of the filter element, thereby quickly completing the installation and positioning of the filter element.

[0026] Compared with the prior art, this device removes the filter element by pushing a baffle and then pulling it out, making the overall operation process simpler and less likely to damage the interface. Attached Figure Description

[0036] Example: Referring to the accompanying drawings, this utility model provides a filter element installation structure, including a fixing mechanism 100. The fixing mechanism 100 includes two vertical tracks 111 extending toward the installation position of the filter element 444 and forming an installation space on the housing 555 outside the installation position of the filter element 444. In addition, the baffle 112 that blocks the installation position of the filter element 444 extends outward from the track 111 to form a barrier 1012 for placing the baffle 112. The baffle 112 slides up and down to partially block the installation position of the filter element 444, preventing the filter element 444 from detaching from the installation position. A number of sliders 1021 are connected to the baffle 112 and slide in the track 111. The baffle 112 is located at the bottom of the travel of the track 111 and blocks the installation position of the filter element 444, making it less likely for the baffle 112 to slide accidentally and cause the filter element 444 to loosen. The sliders 1021 are provided with screw holes. Screws 1022 that form a stop with the edge of the track 111 are screwed into the screw holes. When disassembling, the screws 1022 can be removed to separate the baffle 112 from the track 111. A number of protrusions 1011 are evenly connected to the inner wall of the track 111, and a number of stop brackets 1023 that form a locking position with the protrusions 1011 are connected to the baffle 112. The movable side of the protrusions 1011 facing the stop brackets 1023 is designed with an incline, and the end of the stop brackets 1023 is L-shaped and hooked to the edge of the track 111. It also includes a positioning mechanism 200, which is disposed opposite to the filter element 444 and the housing 555. The positioning mechanism 200 includes a plurality of extrusion strips 211 connected to the filter element 444 and in close contact with the baffle 112 in the shielding state. The extrusion strips 211 are arc-shaped in the direction of movement of the baffle 112. The positioning mechanism 200 also includes an open positioning rail 212 opened at the pipeline position of the housing 555. The positioning strip 213 connected to the filter element 444 slides into the positioning rail 212. The open part of the positioning rail 212 is designed as a flared mouth.

[0037] During installation, the baffle 112 is positioned at the top of the track 111, exposing the installation position of the filter element 444 on the housing 555. Then, the filter element 444 is pushed in, allowing the positioning strip 213 to continuously enter the positioning track 212 until the filter element 444 is tightly connected to the pipeline of the housing 555. Finally, the baffle 112 is pulled down, allowing the slider 1021 and the stop bracket 1023 to descend in the track 111 until the stop bracket 1023 is engaged with the corresponding protrusion 1011, so that the baffle 112 is located in the enclosure 1012 and closely adheres to the extrusion strip 211, forming a limit on the filter element 444. During disassembly, the operation is reversed.
