Description

Technical Field

[0001] This utility model relates to the field of filters, specifically a waterproof cover plate for filters. Background Technology

[0002] Filters are widely used in many electronic devices, especially those that work outdoors or in humid environments, where waterproofing is crucial. While traditional filter covers offer some waterproofing, they still have shortcomings. For example, gaps between the cover and the cavity allow water to slowly seep in, and water evaporates slowly between the sealing ring and the gap. Over time, this water may accumulate and seep into the cavity, corroding the resonant column and affecting the filter's lifespan and performance. Therefore, a waterproof cover for filters is needed.

[0003] Existing waterproof covers for filters are inconvenient for allowing water to enter the device during operation and are not convenient for assisting in the installation of the device. Therefore, there is an urgent need for a waterproof cover for filters. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a waterproof cover for a filter, so as to solve the problem that existing waterproof covers for filters are inconvenient for waterproofing the device and for assisting in the installation of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof cover plate for a filter, comprising a cover plate body, wherein a first sealing ring is adhered to the inner wall of the cover plate body, the outer wall of the first sealing ring abuts against a shell, a second sealing ring is adhered to the inner wall of the shell, a fixing rod is fixedly connected to the inner wall of the cover plate body, and a fixing sleeve is fixedly connected to the outer wall of the fixing rod.

[0006] Springs are welded to the outer wall of the cover plate body. A guide frame is welded to one end of the spring. A first magnetic sleeve is adhered to the outer wall of the guide frame. A second magnetic sleeve is attached to the outer wall of the first magnetic sleeve.

[0007] Preferably, the inner wall of the cover plate body is tightly fitted with the outer wall of the first sealing ring, and the width of the inner wall of the cover plate body is greater than the width of the outer wall of the first sealing ring.

[0008] Preferably, the cover plate body is engaged with the housing, and the inner wall of the cover plate body has a slotted design.

[0009] Preferably, the cover plate body is engaged with the fixing rod, and the fixing rod is symmetrically arranged about the central axis of the cover plate body.

[0010] Preferably, the guide frame is movably connected to the cover plate body, and the inner wall of the cover plate body has an open design.

[0011] Preferably, the outer wall of the guide frame is in close contact with the inner wall of the first magnetic sleeve, and the first magnetic sleeve is configured with a trapezoidal structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model provides a tight fit between the cover plate body and the first sealing ring. The edge of the cover plate body is provided with multiple layers of intersecting protrusions and grooves, which fit tightly with the corresponding grooves and protrusions on the shell. When water tries to penetrate through the gap, it needs to travel along a maze-like path, which greatly increases the difficulty of water entering the interior and prolongs the water penetration path, effectively blocking most of the water. At the same time, the combination of the first sealing ring and the second sealing ring further increases the waterproofness.

[0014] 2. This utility model provides a guide frame to ensure a tight fit between the first magnetic sleeve and the guide frame. The spring abuts against the guide frame, causing it to protrude from the cover plate body. The housing and the second magnetic sleeve magnetically attract and guide the guide frame and the first magnetic sleeve, facilitating the auxiliary installation of the cover plate body and the housing, thus increasing the practicality of the device.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4A waterproof cover plate for a filter includes a cover plate body 1. A first sealing ring 2 is adhered to the inner wall of the cover plate body 1. The inner wall of the cover plate body 1 is tightly fitted to the outer wall of the first sealing ring 2, and the width of the inner wall of the cover plate body 1 is greater than the width of the outer wall of the first sealing ring 2. The outer wall of the first sealing ring 2 abuts against a housing 3. The cover plate body 1 and the housing 3 are engaged. The inner wall of the cover plate body 1 has a slotted design. A second sealing ring 4 is adhered to the inner wall of the housing 3. A fixing rod 5 is fixedly connected to the inner wall of the cover plate body 1. The cover plate body 1 and the fixing rod 5 are engaged. The cover plate body 1 is symmetrically arranged along its central axis. The outer wall of the fixing rod 5 is fixedly connected to the fixing sleeve 6. The cover plate body 1 provides a tight fit with the first sealing ring 2. The edge of the cover plate body 1 is provided with multiple layers of intersecting protrusions and grooves, which fit tightly with the corresponding grooves and protrusions on the shell 3. When water tries to penetrate through the gap, it needs to travel along a maze-like path, which greatly increases the difficulty for water to enter the interior and prolongs the water penetration path, effectively blocking most of the water. At the same time, the combination of the first sealing ring 2 and the second sealing ring 4 further increases the waterproofness.
