[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an energy-saving and environmentally friendly ventilation device, including a ventilation pipe 1, a ventilation fan 6 fixedly installed on the inner side of the ventilation pipe 1, two dustproof nets 4 provided on the inner side of the ventilation pipe 1 and on one side of the ventilation fan 6, the ventilation pipe 1 and the two dustproof nets 4 are connected by two installation components 2, an energy-saving purification device 3 is fixedly installed on one side of the ventilation pipe 1 and on the side of the two dustproof nets 4 away from the ventilation fan 6, and a drying treatment device 5 is installed at the lower part of the ventilation pipe 1.

[0023] Specifically, the energy-saving purification device 3 includes a connecting pipe 31, a rotating shaft 32, a first fan blade 33, a purification component 34, a first gear 35, a second gear 36, a second fan blade 37, a connecting shaft 38, and a support plate 39. The connecting pipe 31 is fixedly installed on one side of the ventilation pipe 1, on the side away from the ventilation fan 6 from the two dust screens 4. A rotating shaft 32 is mounted on the central position of the connecting pipe 31 via a bearing. The first fan blade 33 is fixedly installed on the outer side of the rotating shaft 32, on both the upper and lower sides of the connecting pipe 31. The outer side of the rotating shaft 32 and... A first gear 35 is fixedly installed inside the connecting pipe 31. A support plate 39 is fixedly installed inside the connecting pipe 31 and on one side of the first gear 35. A connecting shaft 38 is installed on the lower inner side of the support plate 39 via a bearing. A second gear 36 is fixedly installed on the side of the connecting shaft 38 close to the first gear 35. A second fan blade 37 is fixedly installed on the outer side of the connecting shaft 38 and on the side of the support plate 39 away from the first gear 35. Multiple purification components 34 are provided on the side of the first gear 35 away from the second fan blade 37.

[0024] By adopting the above technical solution, staff can utilize external airflow for ventilation through the cooperation of the first blade 33 and the second blade 37, thereby improving the energy-saving and environmental protection effect of the equipment and better meeting the needs of the work.

[0025] Specifically, the purification component 34 includes activated carbon 342 and mesh cylinders 343. Multiple mesh cylinders 343 are fixedly installed inside the connecting pipe 31 and on the side of the first gear 35 away from the second fan blade 37. The inside of the mesh cylinders 343 is filled with activated carbon 342.

[0026] By adopting the above technical solutions, staff can purify odors in the air when needed using activated carbon 342 and other structures, thereby better meeting the needs of staff and reducing the possibility of discomfort for people indoors.

[0027] Specifically, the purification component 34 also includes threaded blocks 341, and multiple threaded blocks 341 are threadedly installed at the top and bottom of the connecting pipe 31 and at the upper and lower sides of the multiple mesh cylinders 343.

[0028] By adopting the above technical solution, the staff can unscrew the threaded block 341 to replace the activated carbon 342 when needed, thereby reducing the difficulty of replacing the activated carbon 342 and reducing the workload of the staff.

[0029] In this embodiment, when ventilation is required, the equipment is placed in the working position, and the first fan blades 33 on both sides of the connecting pipe 31 in the energy-saving purification device 3 are exposed to the outside. When there is no airflow, the staff can start the ventilation fan 6 to draw in outside air for ventilation. When there is airflow, the staff does not need to start the ventilation fan 6. The first fan blades 33 are driven by the outside airflow, thereby driving the rotating shaft 32 and the first gear 35 on it to rotate. Then, through the second gear 36, the connecting shaft 38 and the second fan blades 37 on it are driven to rotate, thereby blowing outside air into the ventilation pipe 1 for ventilation. The support plate 39 is connected to the connecting shaft 38 by a bearing. When air passes through the equipment, the activated carbon 342 in the mesh cylinder 343 of each purification component 34 can purify the odor in the air. The two dustproof nets 4 can play a role in dust prevention. The installation component 2 plays a connecting role. When needed, the staff can unscrew the threaded block 341 to replace the activated carbon 342.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the drying device 5 includes a lifting plate 51, a lead screw 52, ​​a mesh box 54, silica gel desiccant 55, and a limiting plate 56. The lead screw 52 is installed below the ventilation pipe 1 via a bearing. The lifting plate 51 is installed on the outside of the lead screw 52 via a thread. The mesh box 54 is fixedly installed above the lifting plate 51 and between the two dustproof nets 4. The inside of the mesh box 54 is filled with silica gel desiccant 55. The limiting plate 56 is fixedly installed above the mesh box 54.

[0032] By adopting the above technical solution, staff can treat the moisture passing through the ventilation pipe 1 when needed by using the mesh box 54 and silica gel desiccant 55, thereby reducing the possibility of dampness in the indoor environment.

[0033] Specifically, the drying device 5 also includes a blocking block 53, which is threadedly installed on the inner side of the lifting plate 51 and on one side of the lead screw 52 and below the silica gel desiccant 55.

[0034] By adopting the above technical solution, staff can unscrew the block 53 to replace the silica gel desiccant 55 when needed, thereby reducing the difficulty of replacing the silica gel desiccant 55 and thus reducing the workload of staff.

[0035] In this embodiment, when it is necessary to treat the moisture passing through the ventilation pipe 1, the operator rotates the lead screw 52 in the drying device 5. The lead screw 52 is threadedly connected to the lifting plate 51, and the outer side of the mesh box 54 on the lifting plate 51 is in contact with the bottom of the ventilation pipe 1. Therefore, the lead screw 52 drives the lifting plate 51 and the mesh box 54 to rise until the outer top surface of the lifting plate 51 is in close contact with the outer bottom surface of the ventilation pipe 1. The moisture passing through the ventilation pipe 1 will be absorbed by the silica gel desiccant 55 in the mesh box 54, thereby reducing the possibility of dampness in the indoor environment. When it is not necessary to treat the moisture passing through the ventilation pipe 1, the lead screw 52 is rotated in the opposite direction, thereby driving the lifting plate 51 and the mesh box 54 to descend until the outer bottom surface of the limiting plate 56 is in close contact with the inner bottom surface of the ventilation pipe 1. When necessary, the operator can unscrew the plug 53 to replace the silica gel desiccant 55.

[0036] The structure and principle of the ventilation duct 1, the installation assembly 2 consisting of an installation groove, a slot, a locking block, a locking spring, a sealing gasket, an installation plate, a sealing sleeve, an insert plate, a fixed locking plate, a sliding groove, a movable locking plate, a return spring, a rubber plate, a corrugated sleeve, and an ejector spring, the dustproof net 4, and the ventilation fan 6 in this utility model have been disclosed in an energy-saving, safe, and environmentally friendly ventilation device disclosed in Chinese Patent Application No. 202420081711.5. Its working principle is that during use, the dustproof net is installed inside the installation groove and inserted into the slot through the insert plate. The fixed locking plate and the locking block form a locking connection, and the sealing gasket and sealing sleeve work together to create a seal between the outer periphery of the dustproof net and the inner wall of the installation groove, thereby improving its density. To prevent air leakage, when the dust filter needs to be disassembled and cleaned, the mounting plate is pushed inward, causing the insert plate to insert deep into the slot. This causes the movable plate to press against the block until it moves to the other side of the block. Then, under the action of the ejector spring, the mounting plate is lifted up. During this process, the insert plate moves outward from the slot, and the movable plate gradually moves closer to the fixed plate along the slide groove until the two merge. Under the continuous action of the ejector spring, the inclined surface of the movable plate presses against the block until the block retracts into the inner wall of the slot. This allows the movable plate and the fixed plate to disengage from the slot under the movement of the insert plate, thus releasing the engagement and facilitating the quick disassembly and cleaning of the dust filter.

[0037] The working principle and usage process of this utility model are as follows: When ventilation is required, the equipment is placed in the working position, with the first fan blades 33 on both sides of the connecting pipe 31 in the energy-saving purification device 3 exposed to the outside. When there is no airflow, the operator can start the ventilation fan 6 to draw in outside air for ventilation. When there is airflow, the operator does not need to start the ventilation fan 6; the first fan blades 33 are driven by the outside airflow, thereby driving the rotating shaft 32 and its first gear 35 to rotate. This, in turn, drives the connecting shaft 38 and its second fan blades 37 to rotate through the second gear 36, thus blowing outside air into the ventilation pipe 1 for ventilation. The support plate 39 is connected to the connecting shaft 38 by a bearing. When air passes through the equipment, the activated carbon 342 in the mesh cylinder 343 of each purification component 34 can purify the odor in the air. The two dustproof nets 4 can play a dustproof role. The mounting component 2 plays a connecting role. When needed, the operator can unscrew the threaded block 341 to replace the activated carbon 342. When it is necessary to treat the moisture passing through the ventilation pipe 1, the operator rotates the screw 52 in the drying device 5. The screw 52 is threadedly connected to the lifting plate 51, and the outer side of the mesh box 54 on the lifting plate 51 is in contact with the bottom of the ventilation pipe 1. Therefore, the screw 52 drives the lifting plate 51 and the mesh box 54 to rise until the outer top surface of the lifting plate 51 is in close contact with the outer bottom surface of the ventilation pipe 1. The moisture passing through the ventilation pipe 1 will be absorbed by the silica gel desiccant 55 in the mesh box 54, thereby reducing the possibility of dampness in the indoor environment. When it is not necessary to treat the moisture passing through the ventilation pipe 1, the screw 52 is rotated in the opposite direction, thereby driving the lifting plate 51 and the mesh box 54 to descend until the outer bottom surface of the limiting plate 56 is in close contact with the inner bottom surface of the ventilation pipe 1. When needed, the operator can unscrew the blocking block 53 to replace the silica gel desiccant 55.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
