Description

Technical Field

[0001] This utility model relates to the field of air filters, specifically to an air filter with a self-sealing device. Background Technology

[0002] An air filter is a device that uses porous filter materials to capture dust from a gas-solid two-phase flow and purify the gas. It is widely used in cleanrooms, clean factories, laboratories, clean rooms, and electronic, mechanical, and communication equipment to ensure that air cleanliness meets specific requirements.

[0003] A search revealed an invention patent with publication number CN105904942B, which specifically discloses an air filter element. The air filter element has a filter cover and a filter body, wherein the filter body is connected to the filter cover. The air filter element has a drain channel, and the filter cover has a first surface and a second surface facing the first surface, wherein the filter body is connected to the first surface and the drain channel is connected to the second surface.

[0004] Existing air filters work by drawing air in through a fan, filtering it through an internal filter element, and then expelling it through the outlet. However, in practice, because the equipment lacks a sealed structure to isolate it from the outside, if there are odors in the filtered air when the filtration process stops, these odors will remain inside the filter element. After the filter stops working, these odors will leak out through the gaps in the equipment, causing an unpleasant smell around the equipment.

[0005] Therefore, it is necessary to invent an air filter with a self-sealing device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an air filter with a self-sealing device. By rotating a fan and transmitting its power to an internal sealing plate, the sealing plate rotates, thereby opening the interior of the outer casing. When the fan is turned off, the sealing plate resets, thus forming a sealed space inside. This solves the problem in the prior art where the interior and exterior of the device are connected after it stops working, causing the odor generated by the filter element to spread.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air filter with a self-sealing device, including a housing, a fixing frame installed on the upper inner side of the housing, several sets of fans installed below the fixing frame, a set of conical rollers installed below the fan, two sets of filter plates installed inside the housing, and a sealing door installed on one side of the housing, which is used to replace the filter plates after the sealing door is opened.

[0008] A sealing assembly, located inside the housing, is used to seal and isolate the housing from the outside.

[0009] Preferably, the sealing assembly includes a fixing frame, which is installed on the upper part of the inner wall of the housing. Multiple sets of sealing plates are rotatably connected inside the fixing frame, and the sealing plates cover the inside of the fixing frame when they are laid flat.

[0010] Preferably, a rocker arm is installed on one side of each group of sealing plates, and a synchronizing rod is rotatably connected above each group of rocker arms.

[0011] Preferably, a spring is installed between the outermost rocker arm and the inner wall of the housing, and a conical roller is installed on the side of the sealing plate away from the rocker arm.

[0012] Preferably, two sets of fixing frames are arranged vertically inside the outer shell, and the two sets of fixing frames have the same internal structure. The two sets of fixing frames are located on the upper and lower sides of the two sets of filter plates, respectively, and the second conical roller is in contact with the first conical roller.

[0013] Preferably, a double-headed conical roller rod is attached to the lower part of the conical roller, and the double-headed conical roller rod is rotatably connected to the inner wall of the outer shell. The lower part of the double-headed conical roller rod is attached to a conical roller in another set of fixed frames, and the conical roller, the second conical roller, and the double-headed conical roller rod are made of highly wear-resistant material.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] The fan, when turned on, transmits its power to the sealing plates via conical rollers one and two, causing multiple sealing plates to rotate simultaneously. This opens the interior of the fixed frame, allowing the filter plate to filter the air. When the equipment is turned off, the fan shuts off first, causing the spring to reset the multiple sealing plates, sealing the interior of the fixed frame and creating a sealed space inside the casing. This method ensures that the equipment can be in contact with the outside during operation and can be isolated from the outside when not in operation. The entire process is automatically controlled, improving the convenience and practicality of the equipment. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 An air filter with a self-sealing device is shown, including a housing 001, a fixing frame 101 installed on the upper inner side of the housing 001, several sets of fans 102 installed below the fixing frame 101, a conical roller 207 installed below one set of fans 102, two sets of filter plates 103 installed inside the housing 001, and a sealing door 104 installed on one side of the housing 001, which is used to replace the filter plates 103 after the sealing door 104 is opened.

[0026] The sealing component 002 is disposed inside the housing 001 and is used to isolate and seal the housing 001 from the outside.

[0027] Furthermore, in the above structure, the sealing assembly 002 includes a fixing frame 201, which is installed on the upper part of the inner wall of the housing 001. Multiple sets of sealing plates 202 are rotatably connected inside the fixing frame 201, and the sealing plates 202 cover the inside of the fixing frame 201 when they are laid flat.

[0028] The opening or closing of the passage space inside the fixed frame 201 is controlled by rotating the sealing plate 202.

[0029] Furthermore, in the above structure, a rocker arm 203 is installed on one side of each set of sealing plates 202, and a synchronizing rod 204 is rotatably connected above each set of rocker arms 203.

[0030] By rotating a set of rocker arms 203, the rocker arms 203 drive the synchronizing rod 204 to move, thereby enabling multiple sets of rocker arms 203 to rotate simultaneously.

[0031] Furthermore, in the above structure, a spring 205 is installed between the outermost rocker arm 203 and the inner wall of the outer casing 001, and a set of sealing plates 202 is equipped with a conical roller 206 on the side away from the rocker arm 203.

[0032] The spring 205 can pull the rocker arm 203 after it rotates, and can quickly reset it after the rocker arm 203 loses power.

[0033] Furthermore, in the above structure, two sets of fixing frames 201 are arranged vertically inside the outer shell 001, and the internal structure of the two sets of fixing frames 201 is the same. The two sets of fixing frames 201 are located on the upper and lower sides of the two sets of filter plates 103 respectively, and the second conical roller 207 is in contact with the first conical roller 206.

[0034] Through the cooperation of conical roller 1 206 and conical roller 207, the fan 102 can transmit power to the sealing plate 202 after it is turned on and rotates. The rotation of the sealing plate 202 drives the other sealing plates 202 to rotate, thus opening the interior of the fixed frame 201.

[0035] Furthermore, in the above structure, a double-headed conical roller rod 208 is attached to the bottom of the conical roller 206, and the double-headed conical roller rod 208 is rotatably connected to the inner wall of the outer casing 001. The bottom of the double-headed conical roller rod 208 is attached to the conical roller 206 in another set of fixed frames 201. The conical roller 206, the conical roller 207, and the double-headed conical roller rod 208 are made of highly wear-resistant materials.

[0036] The double-headed conical roller rod 208 can simultaneously open the lower sealing plate 202, allowing air to pass smoothly inside the outer casing 001. The high wear-resistant material is a chromium carbide composite material, but not limited to chromium carbide composite material, ensuring that when the sealing plate 202 rotates to a certain position, the conical roller 1 206 and the conical roller 207 will slip, thus maintaining the state of the sealing plate 202. During this process, the conical roller 1 206 and the conical roller 207 will not experience significant wear.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-5 The fan 102 delivers external air into the housing 001. This causes the fan 102 to rotate the conical roller 206, which in turn rotates the conical roller 207, which in turn rotates the double-headed conical roller rod 208. This causes the sealing plate 202 to rotate, and the synchronizing rod 204 drives multiple sets of sealing plates 202 to rotate. This simultaneously opens the interior of both sets of fixed frames 201, allowing the air delivered by the fan 102 to be filtered by the filter core plate 103 and then delivered to the outside through the bottom of the housing 001. When the fan 102 stops working, the spring 205 resets the rocker arm 203, causing each set of sealing plates 202 to return to its original position. This creates a sealed space inside the housing 001, preventing odors from the filter core plate 103 from contacting the outside. This method ensures that the equipment can contact the outside during operation and is isolated from the outside when not in use, with fully automatic control, improving the convenience and practicality of the equipment.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
