Description

Technical Field

[0001] The invention belongs to the technical field of ventilators, and in particular relates to an emission reduction lighting ventilator and a working method thereof. Background Art

[0002] The daylighting ventilator is an innovative ventilation device designed to meet the needs of indoor lighting and ventilation at the same time. Through its unique design, the daylighting ventilator can make full use of natural light to introduce indoor lighting, improve the indoor lighting effect, and effectively realize the circulation of indoor air. It can not only save energy and reduce the number of electric lights used indoors, but also improve the indoor environment and enhance people's work and living quality. Conventional daylighting ventilators are mainly made of transparent materials to realize the input of outdoor light, and a filter device is used to filter the air.

[0003] In factories, ventilators are often used to filter dust inside the factories to reduce emissions and avoid polluting the external environment. The ventilators currently used are mainly composed of a shell, a filter and a ventilation fan. When in use, the ventilation fan generates negative pressure to extract air from the workshop, and the dusty air is filtered and discharged to the outside after passing through the filter. This device will cause the filter to be blocked over a long period of time. The prior art mainly adopts disassembly cleaning and non-disassembly cleaning methods. The former can fully clean the filter, but requires complicated disassembly and assembly. Although the latter does not require disassembly and assembly, it can only clean one side of the filter, and the cleaning effect is poor.

[0004] In order to effectively control the circulation of gas, current ventilators are often equipped with ventilation devices at the ventilation end, which are generally composed of shutters. The air circulation is controlled by opening and closing the shutters. However, this device will be contaminated with dust on the surface of the shutters after long-term use. Since this part is usually installed outdoors and at a high place, maintenance is very inconvenient and improvement is urgently needed. Summary of the invention

[0005] The object of the present invention is to provide an emission reduction lighting ventilator and a working method thereof to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: an emission reduction lighting ventilator comprises a filter box, a ventilation assembly is fixedly installed at the front end of the filter box, an air inlet is opened at the rear end of the filter box, a ventilation fan is movably installed at the middle part of the filter box, a power assembly is installed at the left and right sides of the filter box, the middle part of the power assembly passes through the middle part of the filter box and is fixedly sleeved with the ventilation fan, a filter screen located between the ventilation fan and the air inlet is detachably installed at the rear end of the filter box, a linkage assembly is installed at the upper and lower ends of the filter box, the left and right ends of the linkage assembly are connected to the power assembly, U-shaped plates are provided at the upper and lower ends of the filter box and the ventilation assembly, the U-shaped plate is movably engaged with the filter box and the ventilation assembly and moves up and down relative to the filter box and the ventilation assembly, a linkage frame is fixedly installed between the two U-shaped plates, the front end of the linkage frame is connected to the linkage assembly, and cleaning brushes are installed at the front and back sides of the inner side of the U-shaped plate.

[0007] In the initial state, the ventilation component can be kept in the open state, that is, the ventilation state can be maintained, and the device can be installed at the ventilation hole of the workshop. At the same time, turning on the motor can drive the main shaft to rotate, and drive the ventilation fan to rotate, and generate negative pressure inside the filter box, and suck the air in the workshop into the interior of the filter box through the air inlet. At the same time, after being filtered through the filter net, it is finally discharged through the ventilation component to complete the entire ventilation process.

[0008] As a further technical solution of the present invention, the ventilation assembly includes a fixed frame, which is connected to the front side of the filter box. Two first through grooves are symmetrically provided at the upper and lower ends of the fixed frame. The first through grooves are movably connected to the U-shaped plate, and the U-shaped plate moves up and down relative to the first through grooves.

[0009] As a further technical solution of the present invention, the inner side surface of the fixed frame is movably installed with installation shafts at equal intervals, the outer side surface of the installation shaft is fixedly sleeved with louvers located inside the fixed frame, the louvers rotate relative to the fixed frame, and power gears are installed on both sides of the left and right sides of the installation shaft.

[0010] As a further technical solution of the present invention, racks are provided on both sides of the left and right sides of the fixed frame, and the racks are meshingly connected with the power gear. Extension frames are installed on both sides of the bottom end of the fixed frame, and electric push rods are installed on the top of the extension frames. The output end of the electric push rod is connected to the bottom end of the rack.

[0011] In the initial state, the angle between the louver and the fixed frame is maintained at 45 degrees, that is, the ventilation state is maintained, and the upper and lower U-shaped plates do not block the front and back sides of the fixed frame. If the deflection angle of the louver needs to be adjusted, the electric push rod can be turned on and controlled to shorten. At this time, the rack will drop and drive the power gear in the meshing state to rotate clockwise. At this time, the mounting shaft and the louver will rotate clockwise. At this time, the opening angle of the louver will increase, and the air flow will increase accordingly;

[0012] When the shutters need to be cleaned or the outside air is seriously polluted and the ventilation needs to be closed, the electric push rod can be turned on to control its extension. At this time, the rack moves up and drives multiple power gears to rotate counterclockwise. At this time, multiple mounting shafts and shutters rotate counterclockwise until the shutters are adjusted to a vertical state. When they are completely vertical, the ventilation can be closed.

[0013] By utilizing the rotatable mounting shaft and the coordination between the power gear and the rack, the device can perform stepless adjustment of the ventilation flow rate, thereby ensuring that dust is prevented from leaking out when the device is in a clean state, and that polluted air is prevented from exchanging with indoor air when the external air is severely polluted, thereby improving the practicability of the device, reducing the impact of environmental factors on the ventilation effect, and improving the ventilation quality.

[0014] As a further technical solution of the present invention, the power assembly includes a main shaft, which passes through the middle part of the filter box, and the outer side surface of the main shaft is fixedly sleeved with the middle part of the ventilation fan. The left and right ends of the main shaft are fixedly installed with driving gears located on the outer side surface of the filter box. The power assembly also includes a mounting frame, which is installed on one side of the filter box. A motor is installed on the inner side surface of the mounting frame, and the output shaft of the motor is connected to the driving gear.

[0015] As a further technical solution of the present invention, the outer side surface of the driving gear is movably sleeved with a synchronous toothed belt, the upper and lower ends of the inner side surface of the synchronous toothed belt are meshingly connected with driven gears, the driving gear is meshingly connected to the driven gear through the synchronous toothed belt, and an electromagnetic clutch is installed on the side of the driven gear close to the linkage assembly, the output end of the electromagnetic clutch is connected to the middle part of the driven gear, and a power shaft is installed at the output end of the electromagnetic clutch, and the other end of the power shaft is connected to the linkage assembly.

[0016] In the initial state, the electromagnetic clutch is in the disconnected state. At this time, the motor can drive the main shaft to rotate and drive the ventilation fan to rotate to achieve air suction. At this time, the power cannot be transmitted to the linkage assembly through the driven gear;

[0017] When the device is in a cleaning state, the electromagnetic clutch can be turned on so that the electromagnetic clutch is in a coupled state. At this time, the driving gear can rotate under the drive of the main shaft, and drive multiple upper and lower driven gears to rotate through a synchronous toothed belt, and transmit power to the linkage assembly through the electromagnetic clutch and the power shaft.

[0018] As a further technical solution of the present invention, the linkage assembly includes a locking frame, which is connected to the bottom end of the top of the filter box, and the middle part of the locking frame is movably connected with a linkage shaft, which rotates relative to the locking frame, and the left and right ends of the linkage shaft are connected to the power shaft.

[0019] As a further technical solution of the present invention, a first connecting rod is fixedly connected to the middle part of the left and right ends of the linkage shaft, a second connecting rod is movably connected to the end of the first connecting rod away from the linkage shaft, and a mounting seat is movably connected to the end of the second connecting rod away from the first connecting rod, and the mounting seat is connected to the front end of the linkage frame.

[0020] As a further technical solution of the present invention, when the end of the first connecting rod away from the linkage shaft is at the highest point, the linkage assembly is in an initial state, and the distance between the upper and lower U-shaped plates is a maximum value.

[0021] When the filter becomes clogged after long-term use, the power assembly switches to the power-connected state. The rotation of the power shaft can drive the linkage shaft to rotate. At this time, the first connecting rod on one side of the linkage shaft swings accordingly, and drives the second connecting rod to swing. With the continuous rotation of the linkage shaft, the mounting seat can be driven to move back and forth up and down, and the linkage frame can be driven to move back and forth up and down, and finally the U-shaped plate can be driven to move up and down. At this time, the cleaning brush on the inner side of the U-shaped plate can rub against the front and back sides of the filter to complete the self-cleaning process.

[0022] By utilizing the power required for exhaust by the device and distributing the power through a power assembly, the device can automatically clean the front and rear ends of the filter after being used for a period of time without removing the filter. The entire process is completed automatically without the need to remove the filter, which can effectively avoid the problem of complex disassembly and assembly processes required for traditional devices and improve the cleaning effect.

[0023] At the same time, before cleaning the filter, all the louvers inside the ventilation assembly need to be adjusted to a vertical state, that is, the ventilation is closed. At this time, the front and rear sides of the louver can correspond to the cleaning brush. Due to the up and down reciprocating movement of the linkage frame, the up and down reciprocating movement of the front and rear U-shaped plates can be synchronously driven, that is, the cleaning process of the filter and both ends of the louver is completed at the same time, completing self-cleaning and realizing self-maintenance.

[0024] By utilizing the drive of the linkage component, coordinating the front and rear U-shaped plates, and the coordination between the U-shaped plates and the ventilation component, the device can only perform self-cleaning when the ventilation component is in the closed ventilation state, and can complete the simultaneous cleaning process of the louver and the filter. This not only avoids the problem that traditional devices need to be maintained at high places, but also requires cleaning in the closed ventilation state, effectively avoiding misoperation, preventing dust from overflowing or entering the room, and significantly improving maintenance efficiency.

[0025] A method for operating an emission reduction lighting ventilator comprises the following steps:

[0026] S1: In normal use, the ventilation component can be kept in the open state, and the main shaft can be driven to rotate by turning on the motor. At this time, the ventilation fan on the outer side of the main shaft rotates accordingly, and a negative pressure is generated inside the filter box. At the same time, the air in the workshop is filtered through the filter through the air inlet and finally discharged to the outside through the ventilation component;

[0027] S2: When the outdoor air is polluted, the electric push rod can be turned on to control the extension of the electric push rod, which can drive the rack to rise. At this time, multiple power gears will rotate counterclockwise, and at the same time drive multiple installation shafts to rotate counterclockwise. At this time, the louver will rotate counterclockwise until the louver and the fixed frame are parallel to each other. At this time, the ventilation component can be completely closed to stop ventilation. Otherwise, the electric push rod can be controlled to shorten to continue the ventilation operation;

[0028] S3: When the filter screen is clogged due to long-term filtration, the electromagnetic clutch can be turned on to control it to be in a coupled state. At this time, the main shaft can drive the driving gear to rotate, and drive the driven gear to rotate through the synchronous toothed belt, and drive the power shaft to rotate through the electromagnetic clutch, so that the power can be transmitted to the linkage component;

[0029] S4: At this time, the linkage shaft can rotate accordingly, and at the same time drive the first link to swing, and drive the second link to swing, and apply an upward pulling force and a downward thrust to the mounting seat, and pull the linkage frame to move up and down, and drive the U-shaped plate to move up and down, and at this time, the U-shaped plates located at the upper and lower ends of the filter can self-clean the surface of the filter;

[0030] S5: At the same time, the louver on the inner side of the ventilation assembly can be adjusted to a vertical state, and the U-shaped plates at the upper and lower ends of the louver can be synchronously driven to move up and down through the up and down displacement of the linkage frame, and the cleaning process on both sides of the louver can be completed through the action of the cleaning brush.

[0031] The beneficial effects of the present invention are as follows:

[0032] 1. The present invention utilizes the power required for exhausting the device and distributes the power through a power assembly, so that after a period of use, the device can automatically clean the front and rear ends of the filter without disassembling the filter. The entire process is completed automatically without disassembling the filter, which can effectively avoid the problem that traditional devices require a complicated disassembly and assembly process and improve the cleaning effect.

[0033] 2. The present invention utilizes the drive of the linkage component, cooperates with the front and rear U-shaped plates, and the cooperation between the U-shaped plate and the ventilation component, so that the device can only perform self-cleaning when the ventilation component is in a closed ventilation state, and can complete the simultaneous cleaning process of the louver and the filter screen. It not only avoids the problem that traditional devices need to be maintained at high places, but also must be cleaned in the closed ventilation state, effectively avoiding misoperation, preventing dust from overflowing or entering the room, and significantly improving maintenance efficiency.

[0034] 3. The present invention utilizes a rotatable mounting shaft and the cooperation between a power gear and a rack, so that the device can perform stepless adjustment of the ventilation flow rate, thereby ensuring that dust is prevented from leaking out when the device is in a clean state, and that polluted air is prevented from exchanging with indoor air when the external air is seriously polluted, thereby improving the practicability of the device, reducing the impact of environmental factors on the ventilation effect, and improving the ventilation quality.

[0046] In the initial state, the ventilation component 2 can be kept in the open state, that is, the ventilation state can be maintained, and the device can be installed at the ventilation hole of the workshop. At the same time, turning on the motor 402 can drive the main shaft 403 to rotate, and drive the ventilation fan 3 to rotate, and generate negative pressure inside the filter box 1, and suck the air in the workshop into the interior of the filter box 1 through the air inlet 7, and at the same time, after being filtered by the filter net 6, it is finally discharged through the ventilation component 2 to complete the entire ventilation process.

[0047] like Figure 1 and Figure 3 as well as Figure 4 As shown, the ventilation component 2 includes a fixed frame 201, which is connected to the front of the filter box 1, and two first through grooves 202 are symmetrically provided at the upper and lower ends of the fixed frame 201, and the first through grooves 202 are movably connected with the U-shaped plate 8, and the U-shaped plate 8 moves up and down relative to the first through grooves 202. The inner side surface of the fixed frame 201 is movably installed with mounting shafts 203 at equal intervals, and the outer side surface of the mounting shaft 203 is fixedly sleeved with a louver 204 located inside the fixed frame 201, and the louver 204 rotates relative to the fixed frame 201, and power gears 205 are installed on the left and right sides of the mounting shaft 203, and racks 206 are provided on the left and right sides of the fixed frame 201, and the racks 206 are meshed with the power gear 205.

[0052] like Figure 2 and Figure 6As shown, the power assembly 4 includes a main shaft 403, the main shaft 403 passes through the middle of the filter box 1, the outer side of the main shaft 403 is fixedly sleeved with the middle of the ventilation fan 3, and the left and right ends of the main shaft 403 are fixedly installed with a driving gear 404 located on the outer side of the filter box 1. The power assembly 4 also includes a mounting frame 401, the mounting frame 401 is installed on one side of the filter box 1, and the inner side of the mounting frame 401 is installed with a motor 402, the output shaft of the motor 402 is connected to the driving gear 404, and the outer side of the driving gear 404 is movable A synchronous toothed belt 406 is sleeved, and the upper and lower ends of the inner side of the synchronous toothed belt 406 are meshed with driven gears 405. The driving gear 404 is meshed with the driven gear 405 through the synchronous toothed belt 406. An electromagnetic clutch 408 is installed on the side of the driven gear 405 close to the linkage component 5.

A power shaft 407 is installed at the output end of the electromagnetic clutch 408, and the other end of the power shaft 407 is connected to the linkage component 5.

[0053] In the initial state, the electromagnetic clutch 408 is in the disconnected state. At this time, the motor 402 can drive the main shaft 403 to rotate and drive the ventilation fan 3 to rotate to achieve air suction. At this time, the power cannot be transmitted to the linkage assembly 5 through the driven gear 405;

[0054] When the device is in a cleaning state, the electromagnetic clutch 408 can be turned on so that the electromagnetic clutch 408 is in a coupled state. At this time, the driving gear 404 can rotate under the drive of the main shaft 403, and drive the upper and lower multiple driven gears 405 to rotate through the synchronous toothed belt 406, and transmit the power to the linkage component 5 through the electromagnetic clutch 408 and the power shaft 407.

The entire process is completed automatically without the need to remove the filter 6, which can effectively avoid the problem of traditional devices requiring a complicated disassembly and assembly process and improve the cleaning effect.

[0058] Embodiment: Before cleaning the filter 6, all the louvers 204 inside the ventilation assembly 2 need to be adjusted to a vertical state, that is, the ventilation is closed. At this time, the front and rear sides of the louver 204 can correspond to the cleaning brush 10. Due to the up and down reciprocating movement of the linkage frame 9, the up and down reciprocating movement of the front and rear U-shaped plates 8 can be synchronously driven, that is, the cleaning process of the filter 6 and both ends of the louver 204 is completed at the same time, completing self-cleaning and realizing the self-maintenance process.

[0059] By utilizing the drive of the linkage component 5, coordinating the front and rear U-shaped plates 8, and the coordination between the U-shaped plate 8 and the ventilation component 2, the device can perform self-cleaning only when the ventilation component 2 is in a closed ventilation state, and can complete the simultaneous cleaning process of the louver 204 and the filter 6. This not only avoids the problem that traditional devices need to be maintained at high places, but also requires cleaning in a closed ventilation state, effectively avoiding misoperation, preventing dust from overflowing or entering the room, and significantly improving maintenance efficiency.

At the same time, the air in the workshop is filtered through the filter 6 through the air inlet 7 and finally discharged to the outside through the ventilation component 2;

[0062] S2: When the outdoor air is polluted, the electric push rod 208 can be turned on to control the extension of the electric push rod 208, which can drive the rack 206 to rise, and the multiple power gears 205 rotate counterclockwise, and drive the multiple installation shafts 203 to rotate counterclockwise, and the shutters 204 rotate counterclockwise until the shutters 204 and the fixed frame 201 are parallel to each other.
