For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Combine the following Figures 1 to 10 As shown, an embodiment of the present invention provides an air purification device for building decoration and renovation, comprising: Box body 101, the bottom inner wall of box body 101 is provided with a filter assembly, and the filter assembly is used to filter solid particles in the gas; A purification component is disposed on the top inner wall of the box body 101 and is used to absorb formaldehyde in the gas; An air supply component, which is arranged on the side wall of the box body 101 and is used to introduce fresh air into the room; An exhaust assembly, which is arranged on the side wall of the box body 101 and is used to extract indoor gas; Among them, the purification components include: An outer shell 102, the outer shell 102 is fixed on the top inner wall of the box body 101; A rotating shaft 302, the rotating shaft 302 is rotatably disposed on the top inner wall of the outer shell 102, and the rotating shaft 302 passes through the top of the box body 101; The inner shell 305 is fixed to the bottom of the rotating shaft 302, and the exhaust assembly is connected to the outer shell 102; A control component is disposed at the bottom of the inner shell 305 , and is used to control the connection between the inner shell 305 and the gas supply component so that fresh gas periodically enters the inner shell 305 .

[0026] Furthermore, the purification component also includes: The motor 301 is fixed on the top of the box 101, and the output shaft of the motor 301 and the rotating shaft 302 are fixed; A connecting shaft 602, the connecting shaft 602 is rotatably disposed on the top of the inner housing 305; A plurality of adsorption components, wherein the plurality of adsorption components are arranged on the connecting shaft 602 at equal distances; One-way valve 306 : The one-way valve 306 is arranged through the top of the inner shell 305 .

[0027] When the exhaust component is working, the air pressure in the outer shell 102 decreases. Under the action of the one-way valve 306, the gas in the inner shell 305 enters between the outer shell 102 and the inner shell 305 through the one-way valve 306. In conjunction with the control component, indoor gas or fresh gas can enter the inner shell 305 to achieve the adsorption of formaldehyde in the indoor air or the activation and regeneration of the molecular sieve. During the decoration work, under the action of the one-way valve 306, the indoor gas of poor quality is prevented from entering the inner shell 305, thereby ensuring the activation and regeneration effect of the molecular sieve.

[0028] Furthermore, the adsorption component includes: The mesh plate 605 is fixed on the inner wall of the inner shell 305, and the connecting shaft 602 and the mesh plate 605 are rotatably connected. The mesh plate 605 is used to place the molecular sieve; A plurality of flipping rods 603, which are fixed at equal distances on the side wall of the connecting shaft 602, and the flipping rods 603 are used to flip the molecular sieve, and a magnet 604 is provided at the end of each flipping rod 603; The multiple electromagnets 601 are fixed on the inner wall of the outer shell 102 at equal distances, and the multiple electromagnets 601 correspond to the multiple magnets 604 one by one.

[0029] Under the action of the electromagnet 601 and the magnet 604, and the rotation of the connecting shaft 602, the flipping rod 603 remains fixed relative to the outer shell 102. The rotation of the inner shell 305 drives the mesh plate 605 to rotate, so that the molecular sieve on the mesh plate 605 can be in a relative motion state with the flipping rod 603, thereby achieving the flipping effect of the molecular sieve and ensuring the contact area between the gas and the molecular sieve.

[0030] Furthermore, the control component includes: A third tube body 308, which is disposed through one side of the bottom of the inner shell 305; A connecting seat 701, which is fixed to the bottom of the inner shell 305, and a solenoid valve 707 is provided through the top of the connecting seat 701, and the solenoid valve 707 passes through the inner wall of the bottom of the inner shell 305; An output component, which is disposed on the outer side wall of the connecting seat 701; The rotating disk 307 is rotatably disposed on the inner wall of the bottom of the outer shell 102, and the connecting seat 701 and the third tube body 308 both penetrate the bottom of the rotating disk 307; The first tube 106 is disposed through the bottom of the outer shell 102 and is located directly below the third tube 308; The second tube body 107 is disposed through the bottom of the outer shell 102, and the second tube body 107 is rotatably connected with the connecting seat 701, and the first tube body 106 and the second tube body 107 are both connected with the filter assembly.

[0031] When the turntable 307 rotates, the third tube 308 is driven to move, so that the third tube 308 and the second tube 107 are misaligned. Under the action of the turntable 307, the electromagnetic valve 707 is closed, so that no gas enters the inner shell 305, and the gas pressure in the inner shell 305 is gradually reduced under the operation of the exhaust component, and the low-pressure environment is used to promote the molecular sieve to release formaldehyde. When the third tube body 308 and the second tube body 107 overlap, fresh gas enters the inner shell 305 through the gas supply assembly, the filter assembly, the third tube body 308 and the second tube body 107. The flowing fresh gas flow can also achieve gas flushing of the molecular sieve, further promoting the activation and regeneration effect of the molecular sieve.

[0032] Furthermore, the output components include: Support plate 704, support plate 704 is fixed on the top of rotating disk 307; Telescopic rod 705, the telescopic rod 705 is fixed on the side wall of the support plate 704; An output pipe 702, which is disposed through the outer wall of the connecting seat 701; A plug 703, which is disposed on the telescopic end of the telescopic rod 705 and is used to seal the output pipe 702; Spring 706 , one end of which is fixed to the side wall of the support plate 704 , and the other end of the spring 706 is fixed to the plug 703 .

[0033] When the difference between the air pressure in the connecting seat 701 and the air pressure between the outer shell 102 and the inner shell 305 is extremely large, under the action of the air pressure, the plug 703 can overcome the supporting force provided by the spring 706, so that the output pipe 702 connects the space at both ends of the output pipe 702 (the space in the connecting seat 701, the space between the outer shell 102 and the inner shell 305), thereby ensuring that the inner shell 305 can be in a lower air pressure environment, ensuring the effect of the molecular sieve releasing formaldehyde.

[0034] Furthermore, the filtering component includes: Filter box 103, the filter box 103 is fixed on the bottom inner wall of the box body 101; Partition 104, partition 104 is fixed on the inner wall of the filter box 103, filter screens 105 are fixed on both side walls of the partition 104, and the two filter screens 105 are fixed to the inner wall of the filter box 103, the first tube body 106 and the second tube body 107 are respectively located on both sides of the partition 104, and the first tube body 106 and the second tube body 107 are both located above the filter screen 105.

[0035] Further, the air supply assembly includes: A first installation box 205, which is fixed to the side wall of the box body 101, and an air pump is arranged in the first installation box 205; The air extraction pipe 203 and the connecting pipe 204, the air extraction pipe 203 is arranged on the input port of the air pump, the connecting pipe 204 is arranged on the output port of the air pump, and the connecting pipe 204 runs through the filter box 103, the connecting pipe 204 and the first pipe body 106 are located on the same side of the partition 104, and the connecting pipe 204 is located below the filter screen 105; An air supply pipe 202 is provided through the top of the filter box 103, and the air supply pipe 202 and the connecting pipe 204 are located on the same side of the partition 104; The exhaust seat 201 is fixed on the top of the box body 101 , and the exhaust seat 201 is connected to the air supply pipe 202 .

[0036] During the operation of the air pump, fresh air from the outside is drawn in through the exhaust pipe 203, and then input into the filter box 103 through the connecting pipe 204. After being filtered by one of the filter screens 105 in the filter box 103, it enters the exhaust seat 201 through the air supply pipe 202, and is finally output to the room through the exhaust seat 201, so that fresh air flows indoors.

[0037] Further, the exhaust assembly comprises: A second installation box 501, which is disposed on the side wall of the box body 101, and a vacuum pump is disposed in the second installation box 501; An exhaust pipe 502 and a connecting pipe 503, wherein the exhaust pipe 502 is arranged on the output port of the vacuum pump, and the connecting pipe 503 is arranged on the input port of the vacuum pump, and the connecting pipe 503 is connected to the outer shell 102; The transmission rod 303 is fixed on the rotating shaft 302 . A sealing plate 304 is fixed on the end of the transmission rod 303 . The sealing plate 304 abuts against the inner wall of the outer shell 102 . The sealing plate 304 is used to seal the connecting pipe 503 .

[0038] Furthermore, it also includes: A placement rack 401, the placement rack 401 is arranged on the side wall of the box body 101; An air intake seat 402, the air intake seat 402 is placed on a placement rack 401; The hose 403 has one end connected to the air inlet seat 402 , and the other end of the hose 403 passes through the filter box 103 , and the hose 403 and the second tube body 107 are located on the same side of the partition 104 .

[0039] During decoration work, the end of the exhaust pipe 502 is placed outdoors, the vacuum pump is operated, the gas in the outer shell 102 is extracted through the connecting pipe 503, and the solenoid valve 707 is closed. When the air pressure between the outer shell 102 and the inner shell 305 is extremely low, the indoor gas enters the space between the outer shell 102 and the inner shell 305 through the output pipe 702, and then the indoor gas is discharged to the outdoors through the vacuum pump and the exhaust pipe 502; When not being decorated, the end of the exhaust pipe 502 is placed indoors, and the switch of the solenoid valve 707 is turned on. The indoor gas enters the filter box 103 through the air inlet seat 402 and the hose 403, and after being filtered by the filter 105, enters the connecting seat 701 through the second tube body 107, and then enters the inner shell 305 through the solenoid valve 707. The gas in the inner shell 305 enters the space between the outer shell 102 and the inner shell 305 through the one-way valve 306, and finally is output through the exhaust pipe 502 through the connecting pipe 503 and the vacuum pump. Since the end of the exhaust pipe 502 is indoors at this time, the flow of indoor gas is realized. When the gas flows through the inner shell 305, the formaldehyde is adsorbed by the molecular sieve on the mesh plate 605, which can effectively reduce the formaldehyde volatilized from indoor building materials.

[0040] The specific working methods are: During the non-decoration period, the vacuum pump is turned on, and the end of the exhaust pipe 502 is placed indoors, the air pump is turned off, the solenoid valve 707 is turned on, the air intake seat 402 is removed from the placement rack 401, and the air intake seat 402 is placed at a position far away from the box body 101; During the operation of the vacuum pump, the indoor gas enters the filter box 103 through the air inlet seat 402 and the hose 403, and after being filtered by the filter screen 105, enters the connecting seat 701 through the second tube body 107, and then enters the inner shell 305 through the solenoid valve 707. The gas in the inner shell 305 enters the space between the outer shell 102 and the inner shell 305 through the one-way valve 306, and finally outputs the gas through the exhaust pipe 502 through the connecting pipe 503 and the vacuum pump. Since the end of the exhaust pipe 502 is indoors at this time, the flow of indoor gas is realized. When the gas flows through the inner shell 305, the molecular sieve on the mesh plate 605 adsorbs formaldehyde, which can effectively reduce the formaldehyde volatilized from indoor building materials, so that when the staff enters the room again for construction, the formaldehyde content in the indoor air is at a low state, thereby avoiding the staff from being in a working environment with high concentration of formaldehyde, and ensuring the health of the staff; During the decoration work, the end of the exhaust pipe 203 is placed outdoors, the end of the exhaust pipe 502 is placed outdoors, and the switches of the air pump and the vacuum pump are turned on, and the switch of the solenoid valve 707 is turned off; During the operation of the air pump, fresh air from the outside is drawn in through the air extraction pipe 203, and then input into the filter box 103 through the connecting pipe 204. After being filtered by one of the filter screens 105 in the filter box 103, the fresh air enters the exhaust seat 201 through the air supply pipe 202, and finally outputs to the room through the exhaust seat 201, so that fresh air flows into the room. During the operation of the vacuum pump, the gas in the outer shell 102 is firstly extracted through the connecting pipe 503, and the gas in the inner shell 305 enters the space between the outer shell 102 and the inner shell 305 through the one-way valve 306. Due to the closing of the solenoid valve 707, the air pressure in the inner shell 305 is reduced, which facilitates the molecular sieve to release the adsorbed formaldehyde and promotes the activation and regeneration of the molecular sieve. The released formaldehyde is output by the vacuum pump through the connecting pipe 503 and the exhaust pipe 502. Since the end of the exhaust pipe 502 is outdoors during the construction process, the released formaldehyde is prevented from entering the indoor environment, thereby ensuring the indoor air quality during the construction process. After the inner shell 305 is at an extremely low pressure, the pressure in the outer shell 102 is also extremely low. Under the pressure difference between the connecting seat 701 and the outer shell 102, the plug 703 is pushed by the pressure. Under the action of the telescopic rod 705, the plug 703 moves along the telescopic direction of the telescopic rod 705, compressing the spring 706. When the plug 703 leaves the output pipe 702, the gas in the connecting seat 701 enters the space between the outer shell 102 and the inner shell 305 through the output pipe 702, so that the gas in the filter box 103 close to the outer shell 102 is discharged. The side near the connecting seat 701 is in a negative pressure state. Under the action of negative pressure, the indoor gas enters the space on this side of the filter box 103 through the air inlet seat 402 and the hose 403, so that the indoor gas can be pumped to the outside by the vacuum pump through the air inlet seat 402, the hose 403, the filter box 103, the connecting seat 701, the output pipe 702, the connecting pipe 503, and the exhaust pipe 502, and cooperate with the fresh air output by the exhaust seat 201 to realize the replacement of indoor gas, further ensuring the indoor air quality during the construction process; When the motor 301 is turned on, the motor 301 drives the inner housing 305 to rotate through the rotating shaft 302, and drives the turntable 307 to rotate through the connecting seat 701 and the third tube 308. When the air pressure in the inner housing 305 is extremely low, the inner housing 305 rotates, driving the turntable 307 to rotate, thereby causing the third tube 308 to overlap with the first tube 106. When the third tube 308 overlaps with the first tube 106, the outdoor air on the other side of the partition 104 in the filter box 103 is in the inner housing 305. Under the action of negative pressure, the clean gas enters the inner shell 305 through the first tube body 106 and the third tube body 308. When the clean gas flows through the mesh plate 605, the molecular sieve on the mesh plate 605 is flushed, further promoting the molecular sieve to release formaldehyde, ensuring the effect of molecular sieve activation and regeneration. The rotation of the shaft 302 drives the transmission rod 303 and the sealing plate 304 to move, and the connecting pipe 503 is sealed by the sealing plate 304, so that the molecular sieve can fully contact with the clean gas, further ensuring the effect of molecular sieve activation and regeneration; During the operation of the device, the motor 301 works continuously to drive the inner shell 305 to rotate and ensure that the switch of the electromagnet 601 is turned on. Under the action of the electromagnet 601 and the magnet 604, and the rotation of the connecting shaft 602, the flip rod 603 remains fixed relative to the outer shell 102. The rotation of the inner shell 305 drives the mesh plate 605 to rotate, so that the molecular sieve on the mesh plate 605 can be in a relative motion state with the flip rod 603, thereby achieving the flipping effect of the molecular sieve, ensuring the contact area between the gas and the molecular sieve, which can not only increase the adsorption effect of the molecular sieve on formaldehyde, but also ensure the efficiency of the molecular sieve in releasing formaldehyde when the molecular sieve releases formaldehyde.
