Description

Technical Field

[0001] This invention relates to a nano-formaldehyde removal air purifier that can be drawn in from multiple locations and its usage method. Background Technology

[0002] Air purifiers are products used to improve air cleanliness, and are mainly divided into household, commercial, and medical environments. They can remove formaldehyde and sterilize certain parts of the air by incorporating nano-photocatalysts.

[0003] For example, the existing patent document "CN103353146B Medical Air Purifier" discloses a medical air purifier, including a shell with an air inlet and an air outlet. An air duct is provided within the shell from the air inlet to the air outlet. Within this air duct, a formaldehyde-removing mesh, a nano-photocatalyst mesh, a germicidal ultraviolet lamp, a nano-multi-element catalyst mesh, an activated carbon mesh, a cross-flow fan, and a negative ion emitter are sequentially installed. The negative ion emitter is located near the air outlet. The cross-flow fan is electrically connected to a motor, the germicidal ultraviolet lamp is electrically connected to an ultraviolet circuit board, and the negative ion emitter is electrically connected to a particle accelerator. The motor, ultraviolet circuit board, and particle accelerator are all electrically connected to a main circuit board. This invention can freshen the air and remove external dust, eliminating smoke and PM2.5 fine particulate matter. In medical applications, it can assist in medical treatment and accelerate healing, especially in wards, treatment rooms, and places where a large number of patients are concentrated, achieving prevention and ensuring health.

[0004] While the aforementioned air purifiers can purify the air, they have the following drawbacks: they draw in air through a single top-mounted air inlet, making it difficult to draw in air from a wide range of locations within a room. In medical environments, especially in newly renovated wards, formaldehyde is present in various locations throughout the room. Furthermore, multiple patients live in different beds within a single ward, and each bed area may contain harmful bacteria and germs carried by the patients. Designing only a single air inlet in a fixed location results in air purification treatment only at a single location, failing to evenly draw in the air to be purified from multiple beds, leading to uneven distribution of air purification. Summary of the Invention

[0005] In order to solve the above-mentioned technical problem of single and unadjustable air intake position, the present invention provides a nano-formaldehyde removal air purifier that can draw in air from multiple positions and its usage method.

[0006] The present invention solves the above-mentioned technical problems through the following technical solutions:

[0007] This invention provides a nano-formaldehyde removal air purifier that allows for multi-position air intake, comprising a purifier body having an air outlet and an air inlet; further comprising: a storage base installed on the top of the purifier body, the storage base having multiple equally spaced storage slots with open tops; and multiple unfoldable formaldehyde removal air intake components, each connected to one of the multiple storage slots and retractable into the storage slots, the air outlet of each unfoldable formaldehyde removal air intake component connected to the air inlet of the purifier, and the air inlet of each unfoldable formaldehyde removal air intake component being able to unfold to any position around the purifier body.

[0008] Preferably, the unfolding formaldehyde removal air intake assembly includes an adjustable shaping tube and an air intake panel. The adjustable shaping tube is composed of an inner flexible tube and a gooseneck tube sleeved on the outer wall of the inner flexible tube. The lower part of the adjustable shaping tube is fixedly installed inside the storage tank. One end of the adjustable shaping tube is fixedly connected to a cover, and the other end of the adjustable shaping tube is connected to the air intake panel. The cover is connected to the air intake port located above the purifier body.

[0009] Preferably, the air inlet panel includes an outer panel and two hollow inner panels. The outer panel has grooves on both sides. One end of the hollow inner panel is open and the other end is closed. A piston ring is fixedly fitted to the open end of the hollow inner panel and is connected to the inside of the outer panel. The closed end of the hollow inner panel extends out from the groove on the side of the outer panel. A stop block is fixedly installed in the groove on the side of the outer panel.

[0010] Preferably, a fixing seat is fixedly installed at the inner center of the outer sleeve plate, and a first helical spring is provided on both sides of the fixing seat. One end of the first helical spring is fixedly connected to the side wall of the fixing seat, and the other end of the first helical spring is fixedly connected to the piston ring.

[0011] Preferably, a first mesh plate and a second mesh plate are fixedly fitted and installed on one side of the outer shell panel and one side of the hollow inner panel, respectively. A nano formaldehyde removal mesh is fixedly installed on the mesh surface of the first mesh plate facing the inside of the outer shell panel and on the mesh surface of the second mesh plate facing the inside of the hollow inner panel. An ultraviolet light strip is provided on the nano formaldehyde removal mesh.

[0012] Preferably, a connecting pipe is fixedly connected to the middle of one end of the outer sleeve plate, and the connecting pipe is fixedly connected to one end of the adjusting and shaping tube. A fixing strip is fixedly installed inside the connecting pipe near the adjusting and shaping tube. A retaining ring is fixedly installed inside the connecting pipe near the outer sleeve plate. A cover is provided between the retaining ring and the fixing strip. The cover is elastically connected to the fixing strip by a second helical spring. A sealing gasket is fixedly adhered to one side of the cover. A movable rod is fixedly installed in the middle of the cover and extends into the interior of the outer sleeve plate. Multiple contact blocks are evenly fixedly connected around the cover and contact the inner wall of the connecting pipe. The diameter of the cover is smaller than the inner diameter of the connecting pipe and larger than the inner diameter of the retaining ring. The outer ring of the retaining ring is fixedly connected to the inner wall of the connecting pipe. A limit block is fixedly installed inside the connecting pipe.

[0013] Preferably, a connecting rod is fixedly connected to one end of the movable rod that extends into the inner part of the outer sleeve plate, and both ends of the connecting rod are fixedly installed with a stop seat. The stop seat is an L-shaped plate structure and is provided with a positioning groove.

[0014] Preferably, a connecting strip is fixedly installed on the side of the piston ring facing the stop seat, and the connecting strip is elastically connected to a movable inclined block, the end of which is provided with an inclined surface.

[0015] Preferably, a slider is fixedly connected to the end of the connecting strip, a groove is provided on the movable inclined block, the slider is slidably connected to the groove, and a third helical spring is provided inside the groove. One end of the third helical spring is fixedly connected to the groove wall, and the other end of the third helical spring is fixedly connected to the slider.

[0016] Furthermore, the present invention provides a method of using a nano-formaldehyde removal air purifier, the method comprising the following steps:

[0017] 1. Unfolding: The air inlet panel of the formaldehyde removal air inlet component is unfolded by manually pulling it out of the storage slot, so that the air inlet panel and the gooseneck tube can be pulled out. Due to the characteristic that the gooseneck tube can be bent at will and determined in direction, the air inlet panel can be adjusted to any position.

[0018] 2. Air intake and exhaust: The air purifier body intakes and exhausts air through the air inlet. The air inlet is connected to the connecting pipe via the inner flexible tube in the cover and the adjusting plastic tube. This creates a negative pressure at the end of the connecting pipe connected to the adjusting plastic tube. Combined with the external atmospheric pressure, this creates a pressure difference between the two sides of the cover. The cover, under the pressure of the air, moves within the connecting pipe, opening the retaining ring and compressing the second helical spring until the cover contacts the limit block, switching the connecting pipe from a closed state to an open state. (The closed state is as follows...) Figure 5 As shown, the open state is as follows Figure 8As shown, after the connecting pipe is opened, outside air can enter the interior through the first and second mesh plates on the air inlet panel. Through the nano formaldehyde removal mesh and the ultraviolet light from the ultraviolet lamp strip, the incoming air is treated to remove formaldehyde and sterilize. Then, through the connecting pipe, inner hose and cover, it enters the air inlet of the purifier body for further purification.

[0019] 3. During the extension and pull-out of the air inlet panel, as the connecting pipe switches from the closed to the open state, the movable rod, connecting rod, and stop seat move together with the cover. After movement, the stop seat and the movable inclined block are on the same plane. Then, by manually pulling the hollow inner plates on both sides of the air inlet panel, the hollow inner plates are pulled out from the outer sleeve. The piston ring slides within the outer sleeve until it contacts the stop block and is blocked. During this pull-out process, the piston ring and the fixed seat move relative to each other, stretching the first helical spring and causing it to deform. Further, the inclined surface of the movable inclined block contacts one end of the stop seat, as shown in the contact state. Figure 10 As shown, after the movable inclined block makes contact, it continues to move and is pressed by the stop, causing the slider to slide against the groove. Simultaneously, the third helical spring is compressed, causing the movable inclined block to move until it aligns with the positioning stop groove. The elastic force of the third helical spring then resets the movable inclined block, which then inserts into the positioning stop groove. After insertion, it moves as shown... Figure 6 As shown, when the sides of the air inlet panel are manually loosened, the movable inclined block is blocked by the positioning groove. With the spring of the first spiral spring, the movable inclined block presses against the stop seat to block and keep the hollow inner panel in the pulled-out state, thereby increasing the air inlet surface of a single air inlet panel.

[0020] IV. Storage: After use, the air inlet of the purifier body stops intake, causing the air pressure inside the pipe to drop. The second helical spring's elasticity resets the cover, allowing the sealing gasket on the cover to cover the retaining ring. The pipe switches from the open to the closed state. During this process, the cover moves, causing the movable rod, connecting rod, and retaining seat to move together. This causes the retaining seat and the movable inclined block to no longer be in the same plane, and the movable inclined block separates from the positioning groove, removing the obstruction. The first helical spring's elasticity resets the piston ring, simultaneously pulling the hollow inner plate into the outer outer plate for storage. Then, the air inlet panel and adjusting plastic tube are manually inserted into the storage slot to complete the storage.

[0021] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0022] The positive and progressive effects of this invention are as follows:

[0023] The aforementioned nano-formaldehyde removal air purifier with multi-position air intake and its usage method, through the design of unfolding formaldehyde removal air intake components and a storage base, can be unfolded during use, allowing the air intake ends of multiple unfolding formaldehyde removal air intake components to be deployed to any different positions around the purifier body, facilitating air intake from different positions. This is further applicable to medical environments, allowing the air intake ends of multiple unfolding formaldehyde removal air intake components to be evenly distributed to different bed positions, so that each patient has access to a single unfolding formaldehyde removal air intake component. Simultaneously, the unfolding formaldehyde removal air intake components can face the patient, directly inhaling and purifying the patient's exhaled air for sterilization, avoiding mutual interference among patients in the same ward. After use, the unfolding formaldehyde removal air intake components can be stored in the storage slots of the storage base for convenient storage, reducing the overall size.

[0038] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0039] like Figure 1-12 As shown, a nano-formaldehyde-removing air purifier capable of multi-position air intake includes a purifier body 2, which is provided with an air outlet 201 and an air inlet 202; it also includes: a storage base 3, which is installed on the top of the purifier body 2, and the storage base 3 has multiple equally spaced storage slots 301 with openings at the top; and a set of unfoldable formaldehyde-removing air intake components, which are connected to multiple storage slots 301 respectively. When not in use, the unfoldable formaldehyde-removing air intake components can be stored in the storage slots 301 to reduce the overall volume. The air outlet of the unfoldable formaldehyde-removing air intake component is connected to the air inlet 202 of the purifier. When in use, the air inlet of the unfoldable formaldehyde-removing air intake component can be unfolded to any position around the purifier body 2.

[0040] The number of retractable formaldehyde removal air intake components is selected based on the number of beds in the ward. For example, in a 4-person ward, six components can be installed: four retractable formaldehyde removal air intake components for individual use by the four patients, and two additional components can be reserved for air intake purification in public areas.

[0041] In specific implementation, the bottom of the purifier body 2 is provided with a movable base 1, and casters are provided under the movable base 1, which can be moved on the ground by means of the casters.

[0042] like Figure 1-2As shown, the unfolded formaldehyde removal air intake assembly includes an adjustable shaping tube 4 and an air intake panel 5. The adjustable shaping tube 4 is composed of an inner flexible tube 402 and a gooseneck tube 401 sleeved on the outer wall of the inner flexible tube 402. The lower part of the adjustable shaping tube 4 is fixedly installed inside the storage tank 301. One end of the adjustable shaping tube 4 is fixedly connected to a cover 6, and the other end of the adjustable shaping tube 4 is connected to the air intake panel 5. The cover 6 is connected to the air inlet 202 located above the purifier body 2.

[0043] The design of the gooseneck tube 401 allows for arbitrary adjustment of the air outlet panel's position, and after adjustment, it can be reshaped to maintain the adjusted position. When drawing in external air, the air inlet panel 5 is connected to the air inlet 202 on the top of the purifier body 2 via the hose and cover 6. The air inlet 202 draws in and out air, allowing external air to enter the air inlet panel 5.

[0044] like Figure 3 , Figure 4 as well as Figure 7 As shown, the air inlet panel 5 includes an outer jacket 501 and two hollow inner plates 503. The outer jacket 501 has grooves on both sides. One end of the hollow inner plate 503 is open and the other end is closed. A piston ring 506 is fixedly sleeved on the open end of the hollow inner plate 503 and is connected to the inside of the outer jacket 501. The closed end of the hollow inner plate 503 extends out from the groove on the side of the outer jacket 501. A stop block 507 is fixedly installed in the groove on the side of the outer jacket 501.

[0045] The air inlet panel 5 adopts an expandable design. In use, it extends from the outer panel 501 through the hollow inner panel 503, such as... Figure 4 As shown, this increases the overall air intake surface area, improving the intake range. When not in use, the hollow inner panel 503 is stored inside the outer panel 501, as... Figure 7 As shown, the overall size is reduced to avoid excessive volume, which would make it difficult to store in the storage slot 301 later.

[0046] As an extended technical solution, the hollow inner panel 503 can adopt a flexible design, such as using silicone or rubber materials, which can be deformed and bent. When facing the patient's face, it can be bent to facilitate the encirclement of the patient's face during the direct suction of the patient's exhaled air. At the same time, a shaping structure can be added inside the hollow inner panel 503, such as using a gooseneck tube 401 installed inside, to provide bending deformation shaping.

[0047] like Figure 4 and Figure 7As shown, a fixing seat 7 is fixedly installed at the center of the inner side of the outer sleeve plate 501. A first helical spring 8 is provided on both sides of the fixing seat 7. One end of the first helical spring 8 is fixedly connected to the side wall of the fixing seat 7, and the other end of the first helical spring 8 is fixedly connected to the piston ring 506.

[0048] like Figure 4 In the case where the air inlet panel 5 is unfolded, the first helical spring 8 is stretched, generating elastic deformation, providing a restoring force for the air inlet panel 5 to be retracted. When the air inlet panel 5 is retracted, it can be automatically retracted with the help of the elastic force of the first helical spring 8. After retraction, as... Figure 7 As shown.

[0049] The design of using the first helical spring 8 for reset facilitates automatic storage, and is especially suitable for cases where the hollow inner plate 503 adopts a flexible design, making it easy to store after bending.

[0050] A first mesh plate 502 and a second mesh plate 504 are fixedly fitted and installed on one side of the outer panel 501 and one side of the hollow inner panel 503, respectively. A nano formaldehyde removal mesh 508 is fixedly installed on the mesh surface of the first mesh plate 502 facing the inside of the outer panel 501 and the mesh surface of the second mesh plate 504 facing the inside of the hollow inner panel 503. An ultraviolet light strip 509 is provided on the nano formaldehyde removal mesh 508.

[0051] The nano formaldehyde removal mesh 508 adopts a mesh structure, which can be made of nylon or steel wire, with nano titanium dioxide attached to it. When combined with the light from the ultraviolet lamp strip 509, it can remove formaldehyde and sterilize.

[0052] The UV light strip 509 emits far-ultraviolet light with a wavelength of 222nm, which has bactericidal properties.

[0053] like Figure 5 and Figure 8As shown, a connecting pipe 505 is fixedly connected to the middle of one end of the outer sleeve plate 501. The connecting pipe 505 is fixedly connected to one end of the adjusting and shaping tube 4. A fixing strip 11 is fixedly installed inside the connecting pipe 505 near the adjusting and shaping tube 4. A retaining ring 15 is fixedly installed inside the connecting pipe 505 near the outer sleeve plate 501. A cover 13 is provided between the retaining ring 15 and the fixing strip 11. The cover 13 is elastically connected to the fixing strip 11 by a second helical spring 12. One side of the cover 13 is fixedly... A sealing gasket 14 is fixedly bonded to the cover 13. A movable rod 9 is fixedly installed in the middle of the cover 13, and the movable rod 9 extends into the interior of the outer sleeve 501. Multiple contact blocks 1301 are evenly fixedly connected around the cover 13, and the contact blocks 1301 are in contact with the inner wall of the connector 505. The diameter of the cover 13 is smaller than the inner diameter of the connector 505, and the diameter of the cover 13 is larger than the inner diameter of the retaining ring 15. The outer ring of the retaining ring 15 is fixedly connected to the inner wall of the connector 505. A limiting block 16 is fixedly installed inside the connector 505.

[0054] When suction is applied to the connector 505, a pressure difference is created between the two sides of the cap 13, causing the cap 13 to move and opening the connector 505. The open state is as follows: Figure 5 As shown, stop suction, and the cap 13 can be closed. The closed state is as follows. Figure 8 As shown.

[0055] One end of the movable rod 9 extending into the inner part of the outer sleeve 501 is fixedly connected to a connecting rod 10. Both ends of the connecting rod 10 are fixedly installed with stop seats 17. The stop seats 17 are L-shaped plate structures and are provided with positioning grooves 1701. When the cover 13 moves, the stop seats 17 can be moved.

[0056] A connecting strip 18 is fixedly installed on the side of the piston ring 506 facing the stop seat 17. The connecting strip 18 is elastically connected to a movable inclined block 19, and the end of the movable inclined block 19 is provided with an inclined surface.

[0057] With its inclined design and flexible connection installation, the movable inclined block 19 can be moved by pressing it against the stop 17.

[0058] A slider 21 is fixedly connected to the end of the connecting strip 18. A groove 20 is provided on the movable inclined block 19. The slider 21 is slidably connected to the groove 20, and a third helical spring 22 is provided inside the groove 20. One end of the third helical spring 22 is fixedly connected to the groove wall of the groove 20, and the other end of the third helical spring 22 is fixedly connected to the slider 21. Through the above structure, the movable inclined block 19 can be elastically installed.

[0059] The air purifier body 2 contains a filter layer and a fan. The filter layer can be an activated carbon filter layer, and the fan drives the airflow to be drawn in.

[0060] This invention provides a method for using a nano-formaldehyde removal air purifier, the method comprising the following steps:

[0061] 1. Unfolding: The air inlet panel 5 of the formaldehyde removal air inlet component is unfolded by manually pulling it out, so that the air inlet panel 5 and the gooseneck tube 401 are pulled out from the storage groove. The air inlet panel 5 can be adjusted to any position by means of the gooseneck tube 401, which can be bent at will and determined in direction.

[0062] 2. Air intake and exhaust: The air purifier body 2 intakes and exhausts air through the air inlet 202. The air inlet 202 is connected to the connecting pipe 505 via the inner flexible hose 402 in the adjusting and shaping tube 4, which in turn connects the cover 6 to the connecting pipe 505. This creates a negative pressure at the end of the connecting pipe 505 connected to the adjusting and shaping tube 4. Combined with the external atmospheric pressure, this creates a pressure difference between the two sides of the cover 13. The cover 13, under the influence of this pressure, moves within the connecting pipe 505, causing the retaining ring 15 to open. Simultaneously, this compresses the second helical spring 12 until the cover 13 contacts the limiting block 16, thus switching the connecting pipe 505 from a closed state to an open state. (The closed state is as follows...) Figure 5 As shown, the open state is as follows Figure 8 As shown, after the connecting pipe 505 is opened, external air can enter the interior through the first mesh plate 502 and the second mesh plate 504 on the air inlet panel 5. Through the ultraviolet light irradiation of the nano formaldehyde removal mesh 508 and the ultraviolet light strip 509, the incoming air is treated to remove formaldehyde and sterilize. Then, through the connecting pipe 505, the inner hose 402 and the cover 6, it enters the air inlet 202 of the purifier body 2 for further purification treatment inside the purifier body 2.

[0063] 3. During the extension and pull-out of the air inlet panel 5, as the connecting pipe 505 switches from the closed state to the open state, the movable rod 9, connecting rod 10, and baffle 17 move together with the cover 13. After the movement, the baffle 17 and the movable inclined block 19 are on the same plane. Then, by manually pulling the hollow inner plates 503 on both sides of the air inlet panel 5, the hollow inner plates 503 are pulled out from the outer plate 501. The piston ring 506 slides in the outer plate 501 until the piston ring 506 contacts the baffle 507 and is blocked. During the above-mentioned pull-out process, the piston ring 506 moves relative to the fixed seat 7, stretching the first helical spring 8 and causing the first helical spring 8 to undergo tensile deformation. Furthermore, the inclined surface of the movable inclined block 19 contacts one end of the baffle 17, and the contact state is as follows. Figure 10As shown, after the movable inclined block 19 makes contact, it continues to move and is pressed by the stop 17, causing the slider 21 to slide against the groove 20. Simultaneously, the third helical spring 22 is compressed, causing the movable inclined block 19 to move until it aligns with the positioning stop groove 1701. The elastic force of the third helical spring 22 then resets the movable inclined block 19, which then inserts into the positioning stop groove 1701. After insertion, as shown... Figure 6 As shown, when the sides of the air inlet panel 5 are manually loosened, the movable inclined block 19 is blocked by the positioning groove 1701. With the spring of the first spiral spring 8, the movable inclined block presses against the stop seat 17 to block and keep the hollow inner plate 503 in the pulled-out state, thereby increasing the air inlet surface of the single air inlet panel 5.

[0064] IV. Storage: After use, the air inlet 202 of the purifier body 2 stops air intake, causing the air pressure in the pipe 505 to drop. The elastic force of the second spiral spring 12 can reset the cover 13, allowing the sealing gasket 14 on the cover 13 to cover the retaining ring 15. The pipe 505 switches from the open state to the closed state. During this process, the cover 13 moves, which can drive the movable rod 9, connecting rod 10 and the stop seat 17 to move together, so that the stop seat 17 and the movable inclined block 19 are not in the same plane. The movable inclined block 19 separates from the positioning groove 1701, removing the obstruction. The elastic force of the first spiral spring 8 resets the piston ring 506, and at the same time pulls the hollow inner plate 503 into the outer plate 501 for storage. Then, the air inlet panel 5 and the adjusting plastic tube are manually inserted into the storage groove 301 to complete the storage.

The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.

8. The method of using the nano-formaldehyde removal air purifier with multi-location air intake as described in any one of claims 1-7, characterized in that: The method of use includes the following steps:

1. Unfolding: The air inlet panel (5) of the formaldehyde removal air inlet component is unfolded by manually pulling it out, so that the air inlet panel (5) and the gooseneck tube (401) are pulled out from the storage tank (301) to unfold. Due to the characteristic that the gooseneck tube (401) can be bent at will and the direction can be determined, the air inlet panel (5) can be adjusted to any position.

2. Air intake and exhaust: The purifier body (2) intakes and exhausts air through the air inlet (202). Through the cover (6) and the inner hose (402) in the adjustment and shaping tube (4), the air inlet (202) is connected to the connecting pipe (505), thereby generating negative pressure at the end of the connecting pipe (505) connected to the adjustment and shaping tube (4). Combined with the action of the external atmospheric pressure, a pressure difference is formed on both sides of the cover (13). The cover (13) is pushed by the air pressure to move in the connecting pipe (505), causing the retaining ring (15) to open. At the same time, the second spiral spring (12) is compressed until the cover is closed. (13) Until it contacts and blocks the limit block (16), the pipe (505) is switched from closed to open. After the pipe (505) is opened, the outside air can enter the interior through the first mesh plate (502) and the second mesh plate (504) on the air inlet panel (5). The air is treated by the ultraviolet light of the nano formaldehyde removal mesh (508) and the ultraviolet light strip (509). Then, the air enters the air inlet (202) of the purifier body (2) through the pipe (505), the inner hose (402) and the cover (6) for further purification.

3. Extension of the air inlet panel (5): During the process of switching the pipe (505) from the closed state to the open state, the movable rod (9), connecting rod (10) and stop (17) move together with the cover (13). After the movement, the stop (17) and the movable inclined block (19) are on the same plane. Then, by manually pulling the hollow inner plate (503) on both sides of the air inlet panel (5), the hollow inner plate (503) is pulled out from the outer plate (501). The piston ring (506) slides in the outer plate (501) until the piston ring (506) contacts the stop (507) and is blocked. During the process of pulling the hollow inner plate (503) out from the outer plate (501), the piston ring (506) moves relative to the fixed seat (7) to stretch the first helical spring (8), so that the first helical spring (8) generates tension. Further, the inclined surface of the movable inclined block (19) contacts one end of the stop (17). After the movable inclined block (19) contacts, it continues to move and is squeezed by the stop (17), causing the slider (21) to slide with the slide groove (20). At the same time, the third spiral spring (22) is compressed, causing the movable inclined block (19) to move until it is aligned with the positioning stop groove (1701). Through the elastic force of the third spiral spring (22), the movable inclined block (19) is reset and inserted into the positioning stop groove (1701). The sides of the air inlet panel (5) are manually loosened. Through the obstruction of the positioning stop groove (1701) by the movable inclined block (19), and with the elastic force of the first spiral spring (8), the movable inclined surface presses against the stop (17) to block and keep the hollow inner plate (503) pulled out, thereby increasing the air inlet surface of the single air inlet panel (5). IV. Storage: After use, the air inlet (202) of the purifier body (2) stops intake, causing the air pressure inside the pipe (505) to drop. Through the elasticity of the second spiral spring (12), the cover (13) can be reset, so that the sealing gasket (14) on the cover (13) covers the retaining ring (15). The pipe (505) switches from the open state to the closed state. During this process, the cover (13) moves, which can drive the movable rod (9), the connecting rod (10) and the retaining seat (17) together. Move the block (17) so that it is not in the same plane as the movable inclined block (19). The movable inclined block (19) separates from the positioning groove (1701), and the obstruction is removed. The piston ring (506) is reset by the elastic force of the first helical spring (8). At the same time, the hollow inner plate (503) is pulled into the outer plate (501) for storage. Then, manually insert the air inlet panel (5) and the adjustment and shaping tube into the storage groove (301) to complete the storage.
