Description

A quick-release air purifier filter Technical Field

[0001] This utility model relates to the field of air purification filter technology, specifically to an air purification filter that can be quickly disassembled and installed. Background Technology

[0002] Air purifiers are devices that effectively improve air cleanliness by adsorbing, decomposing, or transforming various air pollutants such as PM2.5, dust, pollen, odors, formaldehyde and other indoor pollutants, bacteria, and allergens.

[0003] In existing technologies, air purifier filters are generally designed with quick-release structures. This allows for convenient and quick removal, replacement, or cleaning when the filter needs to be removed for cleaning. However, the quick-release structures of existing air purifier filters typically use clips for locking, and these clips rely on their own elasticity for locking. This has drawbacks because air purifier filters need to be removed and replaced multiple times. Since the clips are usually made of plastic, they are prone to deformation or even breakage after repeated replacements, which can affect the filter's fixing effect. Therefore, an improved air purifier filter that can be quickly removed and installed is needed to address this issue. Summary of the Invention

[0004] The purpose of this invention is to provide an air purification filter that can be quickly disassembled and installed, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release air purifier filter, comprising a bottom frame, a housing at the upper end of the bottom frame, a fan compartment fixedly mounted at the upper end of the housing, the fan compartment being in communication with the housing, a motor fixedly mounted at the upper end of the fan compartment, an impeller fixedly mounted at the power output shaft end of the motor, a filter element at the middle of the upper end of the bottom frame, and a quick-fixing mechanism for the filter element between the filter element and the bottom frame, the fixing mechanism comprising a fixed rod, a movable rod, a spring, a pull rod, and a cross frame, a fixed rod fixedly mounted at the middle of the upper end of the bottom frame, a movable rod movably inserted into the upper end of the fixed rod, a spring fixedly mounted at the lower end of the fixed rod, the upper end of the spring being fixedly connected to the movable rod, a pull rod movably mounted at the upper end of the movable rod via a rotating shaft, and a cross frame fixedly mounted inside the filter element.

[0006] Preferably, the surface of the housing is provided with an air inlet, and the surface of the fan compartment is provided with an air outlet. The filtration duct of this device is such that the impeller inside the fan compartment rotates, throwing the air inside the fan compartment out of the air outlet, creating a negative pressure inside the fan compartment. Then, the air inside the housing enters the filter element from the outside of the filter element and then replenishes the fan compartment from the inside of the filter element. Meanwhile, the outside air is replenished into the housing from the air inlet. In this way, the airflow is filtered and circulated by the continuous high-speed rotation of the impeller.

[0007] Preferably, casters are movably provided at the four corners of the lower surface of the bottom frame, which allows the entire device to be moved easily.

[0008] Preferably, the housing is interference-fitted into the bottom frame, so that when it is necessary to disassemble and replace the filter element, the housing and the bottom frame can be separated by force, which further facilitates the disassembly of the filter element.

[0009] Preferably, the cross frame has a through hole in the middle.

[0010] Preferably, a dust collection tray is fixedly provided on the outer surface of the lower end of the filter element.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In the entire disassembly process of this utility model, the components of the fixing mechanism, compared with traditional buckles, will not be subjected to combined forces such as tension, bending, and shearing. Thus, the fixing effect of the fixing mechanism can still be guaranteed after repeated disassembly and assembly, thereby ensuring the service life of the device.

[0013] 2. This utility model uses this fixing frame for fixing. After each filter element is fixed, a downward prestressing force can be applied to the filter element so that the lower end of the filter element is tightly attached to the surface of the bottom frame to improve the sealing performance and prevent outside air from entering the filter element from the lower end, thereby improving the fixing effect of the filter element.

[0014] 3. When this utility model filters air, air enters the interior of the filter element from the outside, so that dust will be trapped on the outer surface of the filter element. In order to prevent dust from remaining inside the bottom frame when the filter element is disassembled, a dust collection tray can be used to catch the falling dust, which facilitates subsequent cleaning.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4. This utility model provides a technical solution: a quick-release air purifier filter, including a bottom frame 1, a housing 2 at the upper end of the bottom frame 1, a fan compartment 3 fixedly mounted at the upper end of the housing 2, the interior of the fan compartment 3 being in communication with the interior of the housing 2, a motor 4 fixedly mounted at the upper end of the fan compartment 3, the motor 4 being electrically connected to an external power supply via a control switch, an impeller 5 fixedly mounted at the power output shaft end of the motor 4, and a filter element 6 located in the middle of the upper end of the bottom frame 1. A quick-fixing mechanism for the filter element 6 is provided between the filter element 6 and the bottom frame 1. The fixing mechanism includes a fixing rod 7, a movable rod 8, a spring 9, a pull rod 10, and a cross frame 11. The fixing rod 7 is fixedly installed in the middle of the upper end of the bottom frame 1. The movable rod 8 is movably inserted into the upper end of the fixing rod 7. The spring 9 is fixedly installed in the lower end of the fixing rod 7. The upper end of the spring 9 is fixedly connected to the movable rod 8. The pull rod 10 is movably installed in the upper end of the movable rod 8 through a rotating shaft. The cross frame 11 is fixedly installed inside the filter element 6.

[0022] The surface of the housing 2 is provided with an air inlet 12, and the surface of the fan chamber 3 is provided with an air outlet 13. The filtration duct of this device is such that the impeller 5 inside the fan chamber 3 rotates, throwing the air inside the fan chamber 3 out of the air outlet 13, so that a negative pressure is formed inside the fan chamber 3. Then, the air inside the housing 2 enters the filter element 6 from the outside of the filter element 6 and then replenishes the fan chamber 3 from the inside of the filter element 6. Meanwhile, the outside air is replenished into the housing 2 from the air inlet 12. In this way, the airflow is filtered and circulated by the continuous high-speed rotation of the impeller 5.

[0023] The bottom frame 1 is equipped with casters at the four corners of its lower surface, which allow the entire device to be moved easily.

[0024] The housing 2 is interference-fitted into the bottom frame 1. When it is necessary to disassemble and replace the filter element 6, the housing 2 and the bottom frame 1 can be separated by force, which makes it easier to disassemble the filter element 6.

[0025] A through hole is provided in the middle of the cross frame 11, allowing the movable rod 8 and the pull rod 10 to pass through the lower end of the cross frame 11 and enter the upper end of the cross frame 11. The filter element 6 is fixed as shown in Figure 3. At this time, the movable rod 8 has a strong downward tendency under the contraction of the spring 9, but the pull rod 10 is in a horizontal state. The horizontal pull rod 10 can pull the cross frame 11 downwards, thus moving the filter element 6 downwards, causing the filter element 6 to fit tightly against the surface of the bottom frame 1. This serves to fix the filter element 6 and also applies a downward prestressing force to the filter element 6, ensuring that the lower end of the filter element 6 is tightly attached to the bottom frame. The surface of the frame 1 is reinforced to improve sealing and prevent outside air from entering the filter element 6 from the bottom. When the filter element 6 needs to be disassembled, simply pull the movable rod 8 and the pull rod 10 upwards so that the pull rod 10 can rotate a certain distance from the fixed frame. Then rotate the pull rod 10 to make it vertical, and then lift the filter element 6 upwards. This allows for quick disassembly of the filter element 6. In addition, the components of the fixing mechanism are not subjected to combined forces such as tension, bending, and shearing during the entire disassembly process of the device, unlike traditional buckles. This ensures the fixing effect of the fixing mechanism after repeated disassembly and assembly, thus guaranteeing the service life of the device.

[0026] A dust collection tray 14 is fixedly provided on the outer surface of the lower end of the filter element 6. When the device filters air, the air enters the interior of the filter element 6 from the outside, so the dust will be trapped on the outer surface of the filter element 6. In order to prevent dust from remaining inside the bottom frame 1 when the filter element 6 is disassembled, the dust collection tray 14 can catch the falling dust, which can facilitate subsequent cleaning work.

[0027] Working principle: When using this device, the filtration principle is as follows: the impeller 5 is driven to rotate by the motor 4, which throws the air inside the fan chamber 3 out of the air outlet 13, so that the negative pressure is formed inside the fan chamber 3. Then, the air inside the housing 2 enters the filter element 6 from the outside of the filter element 6 and then replenishes the fan chamber 3 from the inside of the filter element 6. Meanwhile, the outside air is replenished into the housing 2 from the air inlet 12. In this way, the airflow is filtered and circulated by the continuous high-speed rotation of the impeller 5.

[0028] As the device is used for an extended period, the filter element 6 needs to be replaced or cleaned. When replacing the filter element 6, forcefully separate the housing 2 and the bottom frame 1. The filter element 6 will remain on the upper part of the bottom frame 1. At this time, the filter element 6 is firmly fixed to the upper part of the bottom frame 1 by the movable rod 8 and the pull rod 10, which, in conjunction with the cross frame 11, are pulled by the spring 9. To disassemble, simply pull the movable rod 8 and the pull rod 10 upwards, allowing the pull rod 10 to rotate a certain distance from the fixed frame. Then rotate the pull rod 10 to a vertical position, and finally release the movable rod 8 and the pull rod 10. When the movable rod 8 and the vertical pull rod 10 are reset under the action of the spring 9, the movable rod 8 will move to the lower end of the cross frame 11, and then the filter element 6 can be lifted upwards, so that the filter element 6 can be quickly removed. This achieves a quick removal function. Moreover, in the entire disassembly process of the device, the components of the fixing mechanism will not be subjected to combined forces such as tension, bending, and shearing compared to traditional buckles. Only the service life of the spring 9 needs to be considered, without considering the problem of buckle breakage. In this way, the fixing effect of the fixing mechanism can still be guaranteed after repeated disassembly and assembly, thus ensuring the service life of the device.
