Description

Technical Field

[0001] The present invention relates to the technical field of fresh air fans, and particularly to a humidity-adjusting fresh air fan. Background Art

[0002] A humidity-adjusting fresh air fan is a device that combines a fresh air system and a humidity-adjusting function, aiming to provide a more comfortable and healthy indoor environment for users. The humidity-adjusting fresh air fan introduces outdoor fresh air, and after filtering, dehumidifying and other treatments, it is sent into the room to achieve the circulation and renewal of indoor air.

[0003] Chinese Patent with the authorization announcement number CN218179083U discloses a fresh air fan with a humidity-adjusting function, including a placement shell and a fresh air fan main body. The fresh air fan main body is located on the right side of the placement shell. The left side surface of the placement shell is fixedly communicated with an air inlet pipe, and the right side surface of the placement shell is fixedly communicated with a filling air pipe. The right end of the filling air pipe is fixedly communicated with the input end of the fresh air fan main body. Two sealing bearings are fixedly embedded in the inner wall of the placement shell. The inner rings of the two sealing bearings are jointly fixedly connected with a rotating shaft. The outer surface of the rotating shaft is fixedly connected with annularly arranged wind plates. Each wind plate is provided with a placement opening on its outer surface. The inner wall of each placement opening is clamped with a drying plate. Each drying plate is provided with a group of drying holes on its outer surface. A desiccant is placed inside each drying hole. The upper surface of the placement shell is fixedly connected with a maintenance cover through two groups of mounting screws. Two handle grooves are opened on the upper surface of the maintenance cover. A U-shaped card placement plate is fixedly connected inside the placement shell. The inner walls of the two U-shaped card placement plates jointly clamp a purification box. An activated carbon layer plate is arranged inside the purification box. Ventilation windows are fixedly embedded on the left and right side surfaces of the purification box. The inner bottom wall of the placement shell and the bottom surface of the maintenance cover are both fixedly embedded with clamping seats. The top end and the bottom end of the purification box are respectively clamped with the inner walls of the two clamping seats, which can clamp the purification box to increase the stability of the purification box and facilitate the stable use of the purification box. A protective door is hinged to the front surface of the purification box through a hinge. A pull handle groove is opened on the front surface of the protective door, which can facilitate the staff to open the protective door and facilitate the replacement work of the activated carbon layer plate inside the purification box.

[0004] When the above-mentioned fresh air machine is in use, the external fresh air enters the interior of the placement shell through the air inlet pipe, blows the air plate, drives the air plate to rotate, crushes the incoming air, and the air blows onto the drying plate, passes through the drying holes and the desiccant inside, realizing the drying treatment of the air. The dried air is blown into the purification box through the ventilation window, and the activated carbon layer board is used to adsorb and filter impurities in the dried air, realizing the purification of the air. When the activated carbon layer board adsorbs more impurities, its filtering effect on the air will weaken. At this time, the operator can open the protective door to clean or replace the activated carbon layer board inside the purification box. The problem with the above-mentioned fresh air machine during use is that when the activated carbon layer board adsorbs more impurities, the user needs to manually open the protective door, disassemble and remove the activated carbon layer board for cleaning, and then reinstall the cleaned activated carbon layer board in the purification box. The disassembly, cleaning, and installation process of the activated carbon layer board is time-consuming and laborious, very inconvenient, and the user experience is poor. Summary of the Invention

[0005] The present invention provides a humidity-adjusting fresh air machine, aiming to solve the technical problem that the cleaning process of the activated carbon layer board is time-consuming and laborious and very inconvenient when the existing fresh air machine with a humidity adjustment function is in use and the activated carbon layer board adsorbs more impurities.

[0006] The humidity-adjusting fresh air machine of the present invention includes a box body, a gas drying member, and an activated carbon gas filtering member. The gas drying member and the activated carbon gas filtering member are arranged in the box body. The activated carbon gas filtering member can filter the gas entering the box body, and the gas drying member can dry the gas entering the box body. A filtering member cleaning mechanism is further arranged in the box body. The filtering member cleaning mechanism includes a gas impact assembly. The gas impact assembly includes a wind hood and a wind hood driving member. The wind hood driving member is connected to the wind hood through a wind hood transmission assembly. The wind hood driving member can drive the wind hood to repeatedly approach or move away from the activated carbon gas filtering member to form an impact gas acting on the activated carbon gas filtering member.

[0007] The beneficial effects are as follows: When the humidity-adjusting fresh air machine of the present invention is in use, first, the outdoor fresh air is input into the box body, and then the activated carbon gas filtering member adsorbs and filters the dust and impurities carried in the input fresh air. After the filtered fresh air passes through the gas drying member, part of the moisture carried is removed, and the fresh air is dried and then input into the room. When the activated carbon gas filtering member adsorbs more dust and impurities and needs to be cleaned, control the wind hood driving member to work, drive the wind hood to repeatedly approach or move away from the activated carbon gas filtering member to form an impact gas acting on the activated carbon gas filtering member, and blow off the dust and impurities adsorbed on the activated carbon gas filtering member through the impact gas, realizing the automatic cleaning of the activated carbon gas filtering member, without the user having to manually disassemble and remove the activated carbon layer board for cleaning. The cleaning process is time-saving and labor-saving, and very convenient.

[0008] Preferably, the wind hood driving member is a motor. The wind hood transmission assembly includes a wind hood transmission shaft, a rotary extrusion member, a wind hood extrusion fitting, and a wind hood return elastic member. The wind hood driving member is fixedly arranged inside the box body. The wind hood transmission shaft is rotatably arranged inside the box body. The wind hood driving member is in transmission connection with the wind hood transmission shaft to drive the wind hood transmission shaft to rotate. The rotary extrusion member is synchronously rotated and arranged on the wind hood transmission shaft. The wind hood is axially slidably arranged on the rotary extrusion member along the wind hood transmission shaft, and the wind hood is rotatably connected to the rotary extrusion member. The two ends of the wind hood return elastic member are respectively fixedly connected to the wind hood and the inner wall of the box body. The rotary extrusion member has a first arc-shaped extrusion surface, and the wind hood extrusion fitting has a first arc-shaped fitting surface that cooperates with the first arc-shaped extrusion surface. When the rotary extrusion member rotates, the first arc-shaped extrusion surface can mutually extrude with the first arc-shaped fitting surface to drive the wind hood to approach the activated carbon gas filter along the axis of the wind hood transmission shaft. When the rotary extrusion member disengages from the wind hood extrusion fitting, the wind hood return elastic member can drive the wind hood to reset.

[0009] Preferably, a rotation prevention and cooperation plug rod is arranged on the rotary extrusion member, and a mounting hole is arranged on the wind hood transmission shaft. The rotation prevention and cooperation plug rod is axially slidably inserted into the mounting hole along the wind hood transmission shaft. The rotary extrusion member is connected to the inner wall of the box body through a second return elastic member. The rotary extrusion member is fixedly provided with a compressed air plate through a connecting rod. One end of the connecting rod extends into the wind hood. The compressed air plate is located inside the wind hood. The wind hood and the connecting rod are axially slidably connected along the wind hood transmission shaft. The rotary extrusion member has a second arc-shaped extrusion surface. A second extrusion fitting is fixedly arranged on the inner wall of the box body. The second extrusion fitting has a second arc-shaped fitting surface. The wind hood extrusion fitting has a third arc-shaped fitting surface. When the rotary extrusion member rotates, the second arc-shaped extrusion surface can extrude with the second arc-shaped fitting surface to drive the rotary extrusion member to approach the activated carbon gas filter. The first arc-shaped extrusion surface can move along the third arc-shaped fitting surface and keep the wind hood stationary. When the rotary extrusion member disengages from the second extrusion fitting, the wind hood return elastic member can drive the wind hood to reset.

[0010] The beneficial effect is that when the rotary extrusion member rotates, the second arc-shaped extrusion surface can mutually extrude with the second arc-shaped fitting surface to drive the rotary extrusion member to approach the activated carbon gas filter along the axis of the wind hood transmission shaft. At the same time, the rotary extrusion member drives the connecting rod and the compressed air plate to approach the activated carbon gas filter along the axis of the wind hood transmission shaft, so as to extrude the gas inside the wind hood towards the activated carbon gas filter. When the gas blows towards the activated carbon gas filter, the adsorbed dust and impurities can be blown off, realizing the cleaning of the activated carbon plate.

[0011] Preferably, the activated carbon gas filter includes a mounting plate and an activated carbon plate. The mounting plate is fixedly installed on the inner wall of the box body. The circumferential side wall of the mounting plate is hermetically connected to the circumferential side wall of the box body. Ventilation holes are provided on the mounting plate, and the activated carbon plate is fixedly installed in the ventilation holes.

[0012] Preferably, the filter element cleaning mechanism further includes an impurity collection box, which is arranged on the side of the mounting plate away from the air scoop cover, and the opening of the impurity collection box faces the mounting plate and is arranged opposite to the activated carbon plate.

[0013] Preferably, a sleeve is rotatably arranged on the mounting plate. The rotation axis of the sleeve is parallel to the rotation axis of the air scoop drive shaft. One end of the sleeve passes through the mounting plate and extends towards the air scoop cover, and the other end of the sleeve passes through the mounting plate and extends towards the impurity collection box. At least two sleeves are arranged at intervals. First threaded rods corresponding to each sleeve are fixedly arranged on the air scoop cover. First external threads are arranged on the first threaded rods. Second threaded rods corresponding to each sleeve are fixedly arranged on the impurity collection box. Second external threads are arranged on the second threaded rods. A first internal thread section and a second internal thread section are arranged in the sleeve. The first internal thread section is in threaded cooperation with the first threaded rod, and the second internal thread section is in threaded cooperation with the second threaded rod. The helix directions of the first external thread and the second external thread are opposite.

[0014] The beneficial effect is that when the air scoop cover approaches the activated carbon plate along the axial direction of the air scoop drive shaft, the first threaded rod approaches the activated carbon plate in the sleeve, thereby driving the sleeve to rotate. The rotation of the sleeve drives the second threaded rod to approach the activated carbon plate in the sleeve, thereby driving the impurity collection box to approach the activated carbon plate. It realizes the synchronous movement of the air scoop cover and the impurity collection box towards the activated carbon plate. Thus, when the gas blows off the dust and impurities adsorbed on the activated carbon plate, the impurity collection box can better collect the fallen dust and impurities.

[0015] Preferably, multiple sets of the air scoop drive assemblies and the air scoop covers are arranged in one-to-one correspondence.

[0016] The beneficial effect is that arranging multiple air scoop covers can better clean the activated carbon gas filter element and improve the cleaning effect.

[0017] Preferably, a driving gear is coaxially and fixedly arranged on the output shaft of the air scoop driving member. Driven gears are respectively fixedly arranged on the air scoop drive shafts of each air scoop drive assembly. A transmission chain is connected between the driving gear and each driven gear.

[0018] The beneficial effect is that it realizes the driving of multiple air scoop covers by one air scoop driving member, without the need to additionally set more driving members, reducing the equipment cost.

[0019] Preferably, the filter element cleaning mechanism further includes a vibrating member, which can vibrate the activated carbon gas filter element to shake off the impurities adsorbed on the activated carbon gas filter element.

[0020] The beneficial effect is that the vibrating member can shake loose some of the impurities adsorbed on the activated carbon gas filter element, and then the impact gas can more easily blow off the shaken loose dust and impurities. The vibrating member and the gas impact assembly cooperate with each other to achieve a better cleaning effect.

[0021] Preferably, when the wind hood approaches the activated carbon gas filter element, it can just collide with the activated carbon gas filter element, and the wind hood forms the vibrating member.

[0022] The beneficial effect is that there is no need to set an additional vibration source, which can reduce the equipment cost.

[0023] The beneficial effects of the present invention are as follows: When the humidity-adjusting fresh air blower of the present invention is in use, fresh air outdoors is first input into the box body, and then the activated carbon gas filter element adsorbs and filters the dust and impurities carried in the input fresh air. After the filtered fresh air passes through the gas drying member, part of the moisture carried is removed, and the fresh air is dried and then input into the room. When the activated carbon gas filter element adsorbs a large amount of dust and impurities and needs to be cleaned, control the hood driving member to work, drive the wind hood to repeatedly approach or move away from the activated carbon gas filter element to form an impact gas acting on the activated carbon gas filter element, and blow off the dust and impurities adsorbed on the activated carbon gas filter element through the impact gas, realizing automatic cleaning of the activated carbon gas filter element without the user manually disassembling and taking out the activated carbon layer board for cleaning. The cleaning process is time-saving and labor-saving and very convenient. In addition, when the rotary extrusion member rotates, the second arc-shaped extrusion surface can mutually extrude with the second arc-shaped mating surface to drive the rotary extrusion member to approach the activated carbon gas filter element along the axial direction of the hood transmission shaft. The rotary extrusion member drives the connecting rod and the air compression plate to approach the activated carbon gas filter element along the axial direction of the hood transmission shaft, thereby squeezing the gas inside the wind hood towards the activated carbon gas filter element. When the gas blows towards the activated carbon gas filter element, the adsorbed dust and impurities can be blown off, realizing the cleaning of the activated carbon plate. In addition, it can also realize the synchronous movement of the wind hood and the impurity collection box towards the activated carbon plate, so that when the gas blows off the dust and impurities adsorbed on the activated carbon plate, the impurity collection box can better collect the fallen dust and impurities. In addition, the vibrating member can loosen some of the impurities adsorbed on the activated carbon gas filter element, and then the impact gas can more easily blow off the loosened dust and impurities. The vibrating member and the gas impact assembly cooperate with each other to achieve a better cleaning effect. Description of the Drawings

Detailed implementation manners

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0036] As Figures 1 to 10As shown in the figure, the humidity-adjusting fresh air blower according to the embodiment of the present invention includes a box body 1, a gas drying member, an activated carbon gas filtering member 3, and a filtering member cleaning mechanism. The gas drying member and the activated carbon gas filtering member 3 are fixedly arranged inside the box body 1. An air inlet 11 and an air outlet 12 are formed on the box body 1. The gas drying member is a gas drying cylinder 2, and the gas drying cylinder 2 can remove the moisture in the introduced gas and reduce the humidity of the gas. The gas drying cylinder 2 is a prior art, so its structure and working principle will not be described in detail. A drying inlet and a drying outlet 22 are formed on the gas drying cylinder 2. The air inlet 11 is communicated with the drying inlet, and the air outlet 12 is communicated with the drying outlet 22.

[0037] As Figure 2 shown in the figure, the activated carbon gas filtering member 3 is arranged between the air inlet 11 and the drying inlet. The activated carbon gas filtering member 3 can filter the gas entering the box body 1 and remove impurities such as dust in the gas. The activated carbon gas filtering member 3 includes a mounting plate 31 and an activated carbon plate 32. The mounting plate 31 is fixedly installed on the inner wall of the box body 1. The circumferential side wall of the mounting plate 31 is hermetically connected to the circumferential side wall of the box body 1. Ventilation holes are formed on the mounting plate 31, and the activated carbon plate 32 is fixedly installed in the ventilation holes.

[0038] As Figure 2 and Figure 3 shown in the figure, the filtering member cleaning mechanism includes a gas impact assembly and an impurity collection box 5. The gas impact assembly includes a wind hood 41 and a wind hood driving member 42. The wind hood driving member 42 is connected to the wind hood 41 through a wind hood transmission assembly. The wind hood driving member 42 can drive the wind hood 41 to repeatedly approach or move away from the activated carbon gas filtering member 3 to form an impact gas acting on the activated carbon gas filtering member 3.

[0039] As Figure 2 and Figure 3 shown in the figure, the wind hood transmission assembly includes a wind hood transmission shaft 43, a rotary extrusion member 44, a wind hood extrusion fitting 45, and a wind hood return elastic member 46. The wind hood driving member 42 is a motor, and the wind hood driving member 42 is fixedly installed on the top of the gas drying cylinder 2. The wind hood transmission shaft 43 is rotatably installed inside the box body 1. Specifically, a cross plate 13 is fixedly arranged inside the box body 1. The cross plate 13 is located between the mounting plate 31 and the gas drying cylinder 2. The wind hood transmission shaft 43 is rotatably installed on the cross plate 13 through a bearing. The wind hood transmission shaft 43 passes through the gas drying cylinder 2, and both ends of the wind hood transmission shaft 43 extend outside the gas drying cylinder 2. The wind hood driving member 42 is in transmission connection with the wind hood transmission shaft 43 to drive the wind hood transmission shaft 43 to rotate.

[0040] As Figures 2 - 10As shown, the rotary extrusion member 44 is installed on the wind hood transmission shaft 43, and the rotary extrusion member 44 is located between the transverse plate 13 and the mounting plate 31. The rotary extrusion member 44 is arranged to rotate synchronously with the wind hood transmission shaft 43. Specifically, the rotary extrusion member 44 includes a cylindrical portion 441, a first arc-shaped extrusion portion 442, and a second arc-shaped extrusion portion 443. The cylindrical portion 441 is coaxially arranged with the wind hood transmission shaft 43. The first arc-shaped extrusion portion 442 is fixedly arranged at the lower end of the cylindrical portion 441, and the second arc-shaped extrusion portion 443 is fixedly arranged at the upper end of the cylindrical portion 441. A rotation prevention and mating insertion rod 444 is also fixedly arranged at the upper end of the cylindrical portion 441. The rotation prevention and mating insertion rod 444 is a rectangular rod. An installation hole adapted to the rotation prevention and mating insertion rod 444 is opened at the lower end of the wind hood transmission shaft 43, and an avoidance hole for the rotation prevention and mating insertion rod 444 to insert into the installation hole is opened at the bottom of the transverse plate 13. The rotation prevention and mating insertion rod 444 is inserted into the installation hole, and the rotation prevention and mating insertion rod 444 can slide axially along the wind hood transmission shaft 43 in the installation hole. The rotary extrusion member 44 is also connected to the inner wall of the box body 1 through a second reset elastic member 445. Specifically, the second reset elastic member 445 is a spring. The second reset elastic member 445 is sleeved on the rotation prevention and mating insertion rod 444, and one end of the second reset elastic member 445 is fixedly connected to the transverse plate 13, and the other end of the second reset elastic member 445 is fixedly connected to the upper end of the cylindrical portion 441. A first arc-shaped extrusion surface 4421 is arranged on the first arc-shaped extrusion portion 442, and a second arc-shaped extrusion surface 4431 is arranged on the second arc-shaped extrusion portion 443.

[0041] As Figures 2 - 10 shown, the wind hood 41 is located between the transverse plate 13 and the mounting plate 31 and is correspondingly arranged with the activated carbon plate 32. The wind hood 41 is slidably arranged on the rotary extrusion member 44 along the axial direction of the wind hood transmission shaft 43, and the wind hood 41 is rotatably connected to the rotary extrusion member 44. Specifically, the rotary extrusion member 44 further includes a connecting rod 446 and a pneumatic pressing plate 447. The connecting rod 446 is coaxially and fixedly arranged at the lower end of the cylindrical portion 441, and the pneumatic pressing plate 447 is coaxially and fixedly arranged at the lower end of the connecting rod 446. A jack is opened on the wind hood 41. One end of the connecting rod 446 passes through the jack and extends into the wind hood 41. The pneumatic pressing plate 447 is located inside the wind hood 41. The wind hood 41 is slidably connected to the connecting rod 446 along the axial direction of the wind hood transmission shaft 43 through the jack. The outer peripheral surface of the pneumatic pressing plate 447 is slidably matched with the inner peripheral surface of the wind hood 41 along the axial direction of the wind hood transmission shaft 43. The wind hood reset elastic member 46 is a spring. One end of the wind hood reset elastic member 46 is fixedly connected to the top of the wind hood 41, and the other end of the wind hood reset elastic member 46 is fixedly connected to the bottom of the transverse plate 13, and the elastic force direction of the wind hood reset elastic member 46 is arranged along the axial direction of the wind hood transmission shaft 43.

[0042] As Figure 2 , Figure 4 and Figure 8As shown in the figure, the wind hood extrusion fitting 45 is fixedly arranged on the side of the wind hood 41 facing the first arc extrusion part 442. The wind hood extrusion fitting 45 has a first arc fitting surface 451 that cooperates with the first arc extrusion surface 4421. On the side of the wind hood 41 facing the first arc extrusion part 442, there is also a ventilation hole that communicates the inner and outer spaces of the wind hood 41. The elastic coefficient of the second reset elastic member 445 is greater than that of the wind hood reset elastic member 46. When the rotary extrusion member 44 rotates, the first arc extrusion surface 4421 can mutually extrude with the first arc fitting surface 451 to drive the wind hood 41 to approach the activated carbon plate 32 along the axial direction of the wind hood transmission shaft 43.

[0043] As Figures 8 - 10 shown, the second arc extrusion surface 4431 and the first arc extrusion surface 4421 are symmetrically arranged in the axial direction of the wind hood transmission shaft 43. On the inner wall of the box body 1, a second extrusion fitting 47 is also fixedly arranged through a cross plate 13. Specifically, the second extrusion fitting 47 is fixedly arranged at the bottom of the cross plate 13. The second extrusion fitting 47 has a second arc fitting surface 471 that cooperates with the second arc extrusion surface 4431. The wind hood extrusion fitting 45 also has a third arc fitting surface 452. The third arc fitting surface 452 and the second arc fitting surface 471 are correspondingly arranged in the axial direction of the wind hood transmission shaft 43. In the rotation direction of the wind hood transmission shaft 43, the third arc fitting surface 452 is located in front of the first arc fitting surface 451. When the second arc fitting surface 471 extrudes the rotary extrusion member 44 to move downward, the first arc extrusion surface 4421 can move along the third arc fitting surface 452, and the wind hood 41 can be kept stationary. It should be noted that when the first arc extrusion surface 4421 moves along the third arc fitting surface 452, since the third arc fitting surface 452 is always blocked by the first arc extrusion surface 4421, the wind hood 41 cannot move upward under the reset force of the wind hood reset elastic member 46.

[0044] When the rotary extrusion member 44 rotates, the second arc extrusion surface 4431 can mutually extrude with the second arc fitting surface 471 to drive the rotary extrusion member 44 to move downward along the axial direction of the wind hood transmission shaft 43. At the same time, the rotary extrusion member 44 drives the connecting rod 446 and the air compression plate 447 to move downward along the axial direction of the wind hood transmission shaft 43, thereby squeezing the gas inside the wind hood 41 towards the activated carbon plate 32. When the gas blows towards the activated carbon plate 32, it can blow off the dust and impurities adsorbed on it, realizing the cleaning of the activated carbon plate 32. When the rotary extrusion member 44 disengages from the second extrusion fitting 47, the wind hood reset elastic member 46 can drive the wind hood 41 to reset, and the second reset elastic member 445 can drive the rotary extrusion member 44 to reset.

[0045] As Figures 2 - 4As shown in the figure, the impurity collection box 5 is arranged on the side of the mounting plate 31 away from the air scoop 41. The opening of the impurity collection box 5 faces the mounting plate 31 and is arranged opposite to the activated carbon plate 32. Specifically, a sleeve 6 is rotatably arranged on the mounting plate 31. The rotation axis of the sleeve 6 is parallel to the rotation axis of the air scoop transmission shaft 43. One end of the sleeve 6 passes through the mounting plate 31 and extends towards the air scoop 41, and the other end of the sleeve 6 passes through the mounting plate 31 and extends towards the impurity collection box 5. The sleeve 6 is rotatably mounted on the mounting plate 31 through a bearing. There are two sleeves 6 arranged at intervals. A first threaded rod 411 corresponding to each sleeve 6 is fixedly arranged on the air scoop 41, and a first external thread is arranged on the first threaded rod 411. A second threaded rod 51 corresponding to each sleeve 6 is fixedly arranged on the impurity collection box 5, and a second external thread is arranged on the second threaded rod 51. A first internal thread section and a second internal thread section are arranged in the sleeve 6. The first internal thread section is in threaded cooperation with the first threaded rod 411, and the second internal thread section is in threaded cooperation with the second threaded rod 51. The helix directions of the first external thread and the second external thread are opposite.

[0046] When the air scoop 41 approaches the activated carbon plate 32 along the axial direction of the air scoop transmission shaft 43, the first threaded rod 411 moves downward in the sleeve 6, thereby driving the sleeve 6 to rotate. The rotation of the sleeve 6 drives the second threaded rod 51 to move upward in the sleeve 6, thereby driving the impurity collection box 5 to move upward. It realizes that while the air scoop 41 moves towards the activated carbon plate 32, the impurity collection box 5 is also driven to move towards the activated carbon plate 32. Thus, when the gas blows off the dust and impurities adsorbed on the activated carbon plate 32, the impurity collection box 5 can better collect the falling dust and impurities, preventing the dust and impurities from falling outside the impurity collection box 5.

[0047] As Figure 2 and Figure 3 As shown in the figure, there are three groups of the air scoop transmission components, the air scoops 41, the activated carbon plates 32, and the impurity collection boxes 5 arranged in one-to-one correspondence. A driving gear 421 is coaxially fixedly arranged on the output shaft of the air scoop driving member 42. Driven gears 431 are respectively fixedly arranged on the air scoop transmission shafts 43 of each air scoop transmission component. The driving gear 421 is connected to each driven gear 431 through a transmission chain 422.

[0048] The filter element cleaning mechanism further includes a vibrating member. The vibrating member can vibrate the activated carbon gas filter element 3 to shake off the impurities adsorbed on the activated carbon gas filter element 3. Specifically, the air scoop 41 forms the vibrating member. When the air scoop 41 approaches the activated carbon plate 32, it can collide with the mounting plate 31, causing the activated carbon plate 32 to vibrate. During operation, the impurities adsorbed on the activated carbon plate 32 are shaken loose by the vibrating member, and then the impact gas blows towards the activated carbon plate 32, and it can more easily blow off the shaken loose dust and impurities. The vibrating member and the gas impact component cooperate with each other to achieve a better cleaning effect.

[0049] The implementation principle of the humidity-adjusting fresh air blower according to the embodiments of the present invention is as follows: during use, first, fresh air outdoors is input into the box body 1 through the air inlet 11 by means of a pump or a blower. Then, the fresh air passes through the activated carbon plate 32, and the activated carbon plate 32 adsorbs and filters the dust and impurities carried in the fresh air. The filtered fresh air enters the gas drying cylinder 2 through the drying inlet for drying, and part of the moisture carried by the fresh air is removed. After drying, the fresh air is input into the room. When the activated carbon plate 32 adsorbs a large amount of dust and impurities, affecting its subsequent air purification effect, the user cleans the activated carbon plate 32. The control hood driving member 42 is controlled to drive the hood transmission shaft 43 to rotate, and the hood transmission shaft 43 drives the rotary extrusion member 44 to rotate. During the rotation of the rotary extrusion member 44, the first arc-shaped extrusion surface 4421 first squeezes against the first arc-shaped mating surface 451. Since the elastic coefficient of the second reset elastic member 445 is greater than that of the hood reset elastic member 46, at this time, the second reset elastic member 445 hardly deforms. The first arc-shaped extrusion surface 4421 squeezes the first arc-shaped mating surface 451 to move downward, and the hood reset elastic member 46 is stretched. The air hood 41 approaches the activated carbon plate 32 along the axial direction of the hood transmission shaft 43 until the air hood 41 abuts against the mounting plate 31. At this time, the mounting plate 31 will vibrate slightly, thereby loosening some of the impurities adsorbed on the activated carbon plate 32. Then, the second arc-shaped extrusion surface 4431 squeezes against the second arc-shaped mating surface 471, and the second arc-shaped mating surface 471 squeezes the rotary extrusion member 44 to move downward along the axial direction of the hood transmission shaft 43, and the second reset elastic member 445 is stretched. During the downward movement of the rotary extrusion member 44, the rotary extrusion member 44 drives the connecting rod 446 and the air compression plate 447 to move downward along the axial direction of the hood transmission shaft 43, squeezing the gas inside the air hood 41 towards the activated carbon plate 32. When the gas blows towards the activated carbon plate 32, the adsorbed dust and impurities are blown off, realizing the cleaning of the activated carbon plate 32. The rotary extrusion member 44 continues to rotate. When the second arc-shaped extrusion surface 4431 of the rotary extrusion member 44 disengages from the second arc-shaped mating surface 471 of the second extrusion fitting 47, the second reset elastic member 445 drives the rotary extrusion member 44 to reset. At the same time, the first arc-shaped extrusion surface 4421 disengages from the third arc-shaped mating surface 452, and the hood reset elastic member 46 drives the air hood 41 to reset. The rotary extrusion member 44 rotates continuously, thereby driving the air hood 41 to approach or move away from the activated carbon gas filter member 3 repeatedly, forming an impact gas acting on the activated carbon gas filter member 3. Moreover, when the air hood 41 abuts against the mounting plate 31, it can loosen some of the impurities adsorbed on the activated carbon plate 32, and then the impact gas can more easily blow off the loosened dust and impurities, achieving a better cleaning effect. The humidity-adjusting fresh air blower of the present invention can realize the automatic cleaning of the activated carbon plate 32, without the user manually disassembling and taking out the activated carbon plate 32 for cleaning. The cleaning process is time-saving, labor-saving and very convenient.
