[0002] The intake HEPA filter is a core filtration component in vacuum cleaners or air purifiers, its function being to efficiently intercept particulate matter such as dust, pollen, and bacteria in the air. HEPA filters are typically made of microfiber material and have extremely high filtration efficiency, reaching over 99.97%. In vacuum cleaners or air purifiers, the intake HEPA filter needs to be correctly installed in the filter compartment to ensure the proper functioning of the equipment.

[0003] During the use of the air intake HEPA filter, the filter inside needs to be replaced regularly according to the frequency of use and environmental requirements to maintain the efficient operation of the air purification equipment. However, in actual use, replacing the filter usually involves rotating or flipping the air intake HEPA filter to open it, which is inconvenient and affects the efficiency of filter replacement. To address this issue, we provide a portable release structure to solve the above-mentioned technical problems. Utility Model Content

An adjustment limiting seat 3 is fixedly arranged inside the adjustment port. An adjustment reset spring 9 is fixedly connected between the release adjustment handle 2 and the adjustment limiting seat 3.

[0020] Furthermore, two release control locking plates 4 are symmetrically slidably arranged inside the support shell 1. The two release control locking plates 4 are located on both sides of the release control handle 2. The two release control locking plates 4 are slidably engaged with the lower end of the release control handle 2, and the release control locking plates 4 are locked with the support shell 1.

[0021] The operation process of this embodiment is as follows: By pulling the release control handle 2, the release control handle 2 moves upward, the control reset spring 9 is compressed, and under the sliding cooperation between the release control handle 2 and the two release control locking plates 4, the two release control locking plates 4 are unrestricted, and then the two release control locking plates 4 move horizontally synchronously and move closer to each other, so that the release control locking plates 4 are released from restriction, thereby completing the release action; When installing, the release control handle 2 is released, and under the elastic recovery action of the control reset spring 9, the release control handle 2 moves downward. Under the sliding cooperation between the release control handle 2 and the two release control locking plates 4, the release control handle 2 squeezes the two release control locking plates 4, so that the two release control locking plates 4 move synchronously and move away from each other, and the release control locking plates 4 are used for limiting.

[0022] For a specific embodiment two, please refer to Figure 1-4 Based on the specific embodiment one, specifically, an air inlet HEPA upper chamber 5 is provided on the lower surface of the supporting shell 1, the air inlet HEPA upper chamber 5 is engaged with the supporting shell 1, and several air inlet HEPA chambers 6 are provided below the air inlet HEPA upper chamber 5. A limit support seat 7 is fixedly connected to the lower surface of the air inlet HEPA chamber 6; the control limit seat 3 is fixedly connected to the inside of the control port through the support frame, and a through opening is opened on the surface of the control limit seat 3. A guide pillar 8 is fixedly connected to the lower surface of the release control handle 2, and the guide pillar 8 slides with the through opening. A support ring is fixedly connected to the lower surface of the guide pillar 8, and a control reset spring 9 is fixedly connected between the support ring and the control limit seat 3.

[0023] Furthermore, two trapezoidal control blocks 10 are fixedly connected to the lower surface of the release control handle 2 via a support column. The side of the trapezoidal control block 10 closest to the corresponding release control lock plate 4 is an inclined sliding surface structure, and the side of the release control lock plate 4 is also an inclined sliding surface structure. The release control lock plate 4 and the corresponding trapezoidal control block 10 slide together, and the release control lock plate 4 has a grid plate structure.

[0024] Furthermore, a support ring 11 is fixedly connected to the upper surface of the air intake HEPA upper compartment 5, and two control plates 12 are symmetrically fixedly connected inside the support shell 1. The control plates 12 pass through the corresponding release control lock plate 4. A locking reset spring 13 is fixedly connected to one side of the control plates 12, and the other end of the locking reset spring 13 is fixedly connected to the corresponding release control lock plate 4. An extension locking block 14 is fixedly connected to one side of the release control lock plate 4. Two locking openings are symmetrically opened on the circumference of the support ring 11, and the extension locking block 14 locks into the corresponding locking opening.

[0025] The operation process of this embodiment is as follows: By pulling the release control handle 2, the release control handle 2 moves upward, and the guide pillar 8 slides upward along the inside of the control port. Under the connecting action of the guide pillar 8, the support ring moves upward synchronously, and the control reset spring 9 is compressed. During this process, under the connecting action of the support pillar, the two trapezoidal control blocks 10 move upward synchronously. Under the sliding cooperation between the trapezoidal control block 10 and the inclined sliding surface of the corresponding release control lock plate 4, the external force on the release control lock plate 4 gradually weakens. Under the elastic recovery action of the locking reset spring 13, the two release control lock plates 4 move horizontally synchronously and approach each other until the extension locking block 14 extends. The release action is completed by disengaging from the corresponding locking slot and releasing the restriction between the supporting shell 1 and the upper air intake HEPA compartment 5. During installation, the release control handle 2 is released. Under the elastic recovery action of the control return spring 9, the release control handle 2 moves down. Under the sliding cooperation of the trapezoidal control block 10 and the inclined sliding surface of the corresponding release control lock plate 4, the trapezoidal control block 10 presses against the inclined sliding surface of the corresponding release control lock plate 4. The release control lock plate 4 is squeezed by external force, which causes the two release control lock plates 4 to move synchronously away from each other. The locking return spring 13 is compressed until the extension locking block 14 is inserted into the corresponding locking slot and is limited by the release control lock plate 4.
