Description

Technical Field

[0001] This utility model relates to the field of air purification device technology, and in particular to an air purification device with a convenient filter replacement. Background Technology

[0002] An air purifier is a device that uses physical, chemical, or biological technologies to remove pollutants (such as dust, smoke, pollen, bacteria, viruses, and harmful gases) from the air to improve indoor or specific space air quality. The core purification capacity of an air purifier depends on its internal filter, which gradually accumulates pollutants during use, so it needs to be replaced or cleaned regularly.

[0003] Currently, existing air purification devices (such as patent number: CN222278815U) disclose air purification devices. This utility model can effectively remove at least some of the microorganisms, dust and harmful gases carried in the air, and also has a pollution-free humidification effect. Furthermore, since hydrogen peroxide solution has low stability at room temperature, the hydrogen peroxide volatilized by the air purification device will also decompose into water and oxygen relatively quickly, and will not cause harm to users in the air environment.

[0004] However, during the implementation of the above technical solutions, at least the following technical problems were found: When replacing and disassembling the existing air filter, additional tools such as screwdrivers are required. The air purifier housing must be disassembled first, and then the air filter must be disassembled. Frequent disassembly using tools will damage the connection points and reduce the efficiency of air filter replacement and cleaning, thus wasting manpower. Utility Model Content

[0021] This application provides an air purification device that allows for convenient filter replacement. It effectively solves the problem that existing air filter replacement and disassembly require additional tools such as screwdrivers, necessitating the removal of the air purifier 1 housing before the air filter 21. Frequent tool use damages the connections and reduces the efficiency of filter replacement and cleaning, resulting in wasted manpower and technical resources. This device, through the cooperation of a suction cup 43 and an ear plate 3, allows for quick and convenient removal and disassembly of the top cover 2 by activating the vacuum generator 4 to release air when replacing it. This eliminates the need for additional tools and simplifies operation.

[0022] Example

[0023] The technical solution in this application embodiment effectively solves the problem that when replacing and disassembling the existing air filter 21, additional tools such as screwdrivers are required to first disassemble the housing of the air purifier 1 and then disassemble the air filter 21. Frequent disassembly using tools will damage the connection points and reduce the efficiency of air filter 21 replacement and cleaning, resulting in a waste of manpower and technical resources. The overall idea is as follows: An air purification device with convenient filter replacement includes an air purifier 1. The air purifier 1 is provided with a fixing mechanism for easy replacement and adjustment. The fixing mechanism includes an upper cover plate 2, an ear plate 3, and a vacuum generator 4. The lower end of the upper cover plate 2 is fixedly installed with... There are two air filters 21, both of which are located on the inner wall of the air purifier 1. Ear plates 3 are fixedly installed on both sides of the upper cover plate 2. Vacuum generator 4 is fixedly installed on the upper end of the upper cover plate 2. An air inlet pipe 11 is fixedly installed on the lower end of the air purifier 1. A magnetic strip 22 is fixedly installed on the lower end of the upper cover plate 2. The magnetic strip 22 is attracted to the inner wall of the air purifier 1. At this time, the user can pull the upper cover plate 2 upward. The upper cover plate 2 moves upward, which will drive the air filter 21 and the magnetic strip 22 to move upward. After the magnetic strip 22 moves upward and leaves the inner wall of the air purifier 1, the magnetic strip 22 is no longer attracted to the inner wall of the air purifier 1.

[0024] The upper ends of both ear plates 3 are provided with mounting grooves 31. The side end of the vacuum generator 4 is provided with a control panel 42. The upper end of the vacuum generator 4 is fixedly installed with a diversion pipe 41. Both ends of the diversion pipe 41 are fixedly installed with air guide pipes 45. The lower end of each air guide pipe 45 is fixedly installed with a suction cup 43. Each suction cup 43 is attracted to the ear plate 3. The user can drive the vacuum generator 4 to release gas. When the vacuum generator 4 starts to release gas, it will transport the gas to each air guide pipe 45 through the diversion pipe 41. When each air guide pipe 45 transfers the gas to the suction cup 43, the suction cup 43 is no longer attracted to the ear plate 3.

[0025] Continue pulling the top cover 2 upwards to move the air filter 21 away from the inner wall of the air purifier 1. At this time, the user can replace or clean the air filter 21. When the replacement or cleaning is completed, the user can insert the air filter 21 on the top cover 2 into the air filter 21, so that the suction cup 43 and the ear plate 3 are attracted to each other. Start the vacuum generator 4 to pump air, which will complete the limiting and fixing of the air filter 21.

[0026] To address the problems existing in the prior art, this utility model provides an air purification device that allows for convenient replacement of the filter element. This device uses a suction cup 43 and an ear plate 3 to work together. When replacing the upper cover plate 2, the upper cover plate 2 can be removed and installed by activating the vacuum generator 4 to release air. It is quick and convenient, requires no additional tools, and is easy to operate.

[0027] Air purifier 1: As the main body of the purification device, it provides a working space for air purification. The inner wall is used to install the air filter 21, and the air inlet pipe 11 at the lower end can be connected to an external air source or exhaust system to realize the introduction of air and the discharge of purified air.

[0028] Air inlet pipe 11: Fixedly installed at the lower end of the air purifier 1, it is the channel for air to enter and exit the purifier, used to connect to external pipes to realize air circulation and ensure the continuity of the purification process.

[0029] Top cover 2: Covers the top of the air purifier 1, with an air filter 21 and a magnetic strip 22 installed at the lower end.

[0030] Air filter element 21: It is fixedly installed at the lower end of the upper cover plate 2 and located on the inner wall of the air purifier 1. It is the core purification component and is used to filter dust, impurities and other pollutants in the air to purify the air.

[0031] Magnetic strip 22: Fixed to the lower end of the upper cover plate 2, it magnetically adsorbs with the inner wall of the air purifier 1, providing initial fixing force and assisting the upper cover plate 2 to be stably installed on the air purifier 1, facilitating quick positioning.

[0032] Ear plate 3: Fixed on both sides of the upper cover plate 2, providing suction position for suction cup 43. The mounting groove 31 at the upper end is used to install suction cup 43, and works with vacuum generator 4 to limit and fix the upper cover plate 2.

[0033] Mounting groove 31: It is opened through the upper end of the ear plate 3 to fix the suction cup 43, so that the suction cup 43 fits tightly with the ear plate 3, ensuring the effective transmission of vacuum adsorption force and ensuring the stability of the upper cover plate 2.

[0034] Vacuum generator 4: Fixed to the upper end of the upper cover plate 2, and controlled to start and stop via control panel 42. When pumping air, the suction cup 43 generates negative pressure to adsorb the ear plate 3 and fix the upper cover plate 2; when releasing air, the adsorption is released, making it easy to remove the upper cover plate 2.

[0035] Diverter pipe 41: Fixed at the upper end of vacuum generator 4, it evenly diverts the airflow generated by vacuum generator 4 to the air guide pipes 45 on both sides, ensuring that the two suction cups 43 work synchronously and are subjected to balanced force.

[0036] Control panel 42: Located at the side end of vacuum generator 4, it is used to control the working state of vacuum generator 4, realize the adsorption or release operation of suction cup 43, and simplify the process of users replacing filter element.

[0037] Suction cup 43: Fixed to the lower end of the air duct 45, it is adsorbed and cooperates with the mounting groove 31 of the ear plate 3. The vacuum generator 4 generates negative pressure to firmly fix the upper cover plate 2 to the air purifier 1 to prevent shaking during the purification process.

[0038] Air guide tube 45: connects the diverter tube 41 and the suction cup 43, transmits the airflow generated by the vacuum generator 4, and transmits the air extraction or venting signal to the suction cup 43 to realize the rapid switching of the suction force of the suction cup 43, ensuring the convenience of filter replacement.

[0039] Working principle:

[0040] During prolonged use, the air filter 21 inside the air purifier 1 will accumulate dust and impurities, therefore it needs to be removed and replaced or cleaned regularly. When replacing or cleaning the air filter 21, the user can drive the vacuum generator 4 to release air. When the vacuum generator 4 starts releasing air, it will deliver the gas to each air guide tube 45 through the diverter tube 41. When each air guide tube 45 transfers the gas to the suction cup 43, the suction cup 43 will no longer adhere to the ear plate 3. At this time, the user can pull the top cover upward. 2. Moving the top cover 2 upwards will cause the air filter 21 and magnetic strip 22 to move upwards. After the magnetic strip 22 moves upwards and leaves the inner wall of the air purifier 1, it will no longer be attracted to the inner wall of the air purifier 1. Continuing to pull the top cover 2 upwards will cause the air filter 21 to leave the inner wall of the air purifier 1. At this time, the user can replace or clean the air filter 21. When the replacement or cleaning is completed, the user can insert the air filter 21 from the top cover 2 into the air filter 21, so that the suction cup... When suction cup 43 and ear plate 3 are attracted together, vacuum generator 4 is activated to evacuate air, thus completing the limiting and fixing of air filter element 21. When replacing or disassembling the existing air filter element 21, additional tools such as screwdrivers are required to first disassemble the housing of air purifier 1, and then disassemble the air filter element 21. Frequent disassembly using tools can damage the connection points and reduce the efficiency of air filter element 21 replacement and cleaning, wasting manpower. This device, by setting suction cup 43 and ear plate 3 to cooperate, allows for the fixing of the upper cover plate 2. When replacing the filter, simply start the vacuum generator 4 to release the air, which allows for the quick and convenient removal and installation of the top cover 2. No additional tools are required, and the operation is simple. Furthermore, this device uses a suction cup 43 and a magnetic strip 22 in combination. The magnetic strip 22 is attached to the inner wall of the air purifier 1, and the suction cup 43 is attached to the upper end of the ear plate 3 to fix the air filter 21 on the top cover 2. This dual-action fixation ensures that the air filter 21 is stably fixed, making it easy to remove without affecting its normal use.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
