Technical Field

[0001] This application belongs to the technical field of air purification equipment, specifically relating to an automatic cleaning device for air conditioning exhaust vent filters, which is particularly suitable for dust removal from air conditioning exhaust vent filters in cigarette factory workshops. Background Technology

[0002] In cigarette factory production workshops, air conditioning systems are crucial for maintaining the temperature and humidity environment, and their exhaust vent filters play a key role in blocking tobacco dust. Over long-term operation, dust accumulating on the filter surface not only significantly reduces ventilation efficiency, but also allows loose dust to easily mix into the material channels, contaminating tobacco raw materials and directly affecting the quality stability of cigarette products.

[0003] However, the traditional method of high-altitude cleaning, which mainly relies on manual binding of brooms, has obvious drawbacks: operators lack safe working support points, it is difficult to cover the dead corners of the filter screen, and the cleaning process causes dust to fly up again. At the same time, the broom fibers need to be replaced frequently due to dust caking, resulting in high maintenance costs.

[0004] Therefore, this application proposes an automated cleaning device that can efficiently remove filter dust, prevent secondary pollution, and eliminate the risks of working at heights. Utility Model Content

[0005] The main purpose of this application is to provide an automatic cleaning device for air conditioning exhaust vent filters, which aims to solve the technical problems of operational hazards, incomplete cleaning, and secondary dust pollution that exist when manually cleaning air conditioning exhaust vent filters in cigarette factories from high altitudes.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0008] As a further improvement of this application, the dust removal mechanism includes a base plate, the upper end face of which has two elongated holes communicating with the inner cavity, a comb plate on the top wall of the base plate and located between the elongated holes, one end of a connecting pipe on the bottom of the left side wall of the connecting plate, a dust collection device on the left side wall of the housing, and the other end of the connecting pipe being fixedly connected to the air inlet of the dust collection device.

[0009] As a further improvement of this application, the dust collection device, connecting pipe, connecting plate, base plate and elongated hole are connected to each other.

[0010] As a further improvement of this application, the right side wall of the housing is provided with a through hole communicating with the inner cavity, and the outer wall of the connecting seat is placed inside the through hole.

[0011] As a further improvement to this application, a plurality of the brush gaps are arranged on the outer wall of the cylinder.

[0012] The technical solution provided in this application may include the following beneficial effects:

[0013] During use, this device is securely installed on the workshop ceiling using a mounting bracket, completely eliminating the risks associated with manual work at height. A first motor drives a high-speed rotating brush to remove dust from the filter screen, while a second motor, via a lead screw, drives the brush to reciprocate, achieving full coverage and deep cleaning of the filter screen.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-3 As shown, an automatic cleaning device for air conditioning exhaust vent filters in a cigarette factory workshop includes a housing 1. A fixed seat 2 is provided on the top wall of the housing 1. A second motor 18 is provided on the front inner wall of the housing 1. The output end of the second motor 18 is locked with a lead screw 3 through a coupling. The rear end of the lead screw 3 is rotatably connected to the inner wall of the housing 1 through a first bearing 4. A connecting seat 5 is threadedly connected to the outer wall of the lead screw 3. The right end of the connecting seat 5 extends out of the housing 1 and is provided with a connecting plate 6. A round rod 8 is rotatably connected to the top of the right side wall of the connecting plate 6 through a second bearing 7. A first motor 9 is provided on the left side wall of the connecting plate 6. The output end of the first motor 9 is fixedly connected to the left end of the round rod 8 through a coupling. A cylinder 11 is provided on the right end wall of the round rod 8. Multiple brushes 12 are provided on the outer wall of the cylinder 11. A dust removal mechanism is provided at the bottom of the outer wall of the connecting plate 6.

[0023] Furthermore, the dust removal mechanism includes a base plate 13, with two elongated holes 14 communicating with the inner cavity on the upper surface of the base plate 13. A comb plate 15 is provided on the top wall of the base plate 13 between the elongated holes 14. One end of a connecting pipe 16 is provided at the bottom of the left side wall of the connecting plate 6. A dust collection device 17 is provided on the left side wall of the housing 1, and the other end of the connecting pipe 16 is fixedly connected to the air inlet of the dust collection device 17. When the dust removal fan on the dust collection device 17 is started, it causes the elongated holes 14 to suck the dust swept down by the brush 12 into the base plate 13 and the connecting plate 6. The dust is then transported into the filter bag on the dust collection device 17 through the connecting pipe 16 for collection. When the brush 12 rotates, it contacts the comb plate 15 at the bottom. The comb plate 15 combs down the dust trapped on the brush 12 and sucks it away through the elongated holes 14, thus cleaning the brush 12.

[0024] Furthermore, the dust collection device 17, connecting pipe 16, connecting plate 6, base plate 13 and elongated hole 14 are connected. After the dust removal fan on the dust collection device 17 is started, it causes the elongated hole 14 to suck the dust swept down by the brush 12 into the base plate 13 and connecting plate 6, and then transport it into the filter bag on the dust collection device 17 for collection through the connecting pipe 16.

[0025] Furthermore, a long through hole communicating with the inner cavity is provided on the right side wall of the housing 1, and the outer wall of the connecting seat 5 is placed in the long through hole, which facilitates the reciprocating movement of the connecting seat 5.

[0026] Furthermore, multiple brushes 12 are spaced apart on the outer wall of the cylinder 11. When the dust removal fan on the dust collection device 17 is started, it causes the elongated hole 14 to suck the dust swept down by the brushes 12 into the base plate 13 and the connecting plate 6. The dust is then transported into the filter bag on the dust collection device 17 through the connecting pipe 16 for collection. By alternately starting the second motor 18 in forward and reverse directions, the brushes 12 and the base plate 13 and other structures can reciprocate back and forth. Through the back and forth covering movement of the brushes 12 under the air conditioner exhaust filter, the dust on the air conditioner exhaust filter can be thoroughly swept down and sucked away for collection.

[0027] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0028] One specific application of this embodiment is:

[0029] In actual use, the installation of this device is very convenient. First, using the fixed base 2, the entire device is firmly installed on the crossbeam of the keel at the top of the cigarette factory workshop by welding or using bolts. During this process, ensure that the installation is firm to ensure the stability of the device during operation. At the same time, make sure that the brush 12 makes precise contact with the air conditioner exhaust filter to prepare for subsequent cleaning work.

[0030] When the air conditioner exhaust vent filter needs to be cleaned, all the components of the device work together to achieve efficient automatic cleaning. The first motor 9 is started, and the power generated by the first motor 9 will cause the circular rod 8 connected to it to start rotating. The circular rod 8, as a transmission component, drives the cylinder 11 closely connected to it and the brush 12 installed on the surface of the cylinder 11 to rotate together. As the brush 12 rotates at high speed, it comes into full contact with the dust adsorbed on the air conditioner exhaust vent filter. Through the friction between the brush bristles and the surface of the filter, the dust is effectively swept off. The swept-off dust falls downwards under the action of gravity.

[0031] At the same time, the dust removal fan on the dust collection device 17 starts, and the powerful suction works through the elongated holes 14. The elongated holes 14 are evenly distributed in specific positions, which can effectively suck the dust swept down and falling by the brush 12 into the space formed by the bottom plate 13 and the connecting plate 6. Subsequently, the dust is smoothly transported along the connecting pipe 16 to the filter bag equipped on the dust collection device 17 for collection. This design allows the dust to be collected quickly after it is generated, avoiding the dust from flying around in the workshop again and ensuring the cleanliness of the air in the workshop.

[0032] It is worth mentioning that during the rotation of the brush 12, its bottom will remain in contact with the comb plate 15. The comb plate 15 is ingeniously designed, which can effectively comb down the dust trapped between the bristles of the brush 12 when the brush 12 rotates. The combed dust will also be sucked away by the vacuuming device through the elongated hole 14. This ingenious design not only ensures the cleanliness of the brush 12 and maintains its good cleaning performance, but also helps to extend the service life of the brush 12, reduce the frequency of brush replacement, and reduce the cost of use.

[0033] In addition, the start of the second motor 18 brings a more comprehensive cleaning effect to the entire cleaning device. After the second motor 18 starts, the drive screw 3 begins to rotate. As a key transmission component, the screw 3, through cooperation with the connecting seat 5, causes the connecting seat 5 to drive a series of connected structures, including the connecting plate 6, the round rod 8, the first motor 9, the cylinder 11, the brush 12, the base plate 13, the comb plate 15, and the connecting pipe 16, to move forward or backward together. By controlling the second motor 18 to start in both forward and reverse directions alternately, the reciprocating motion of the brush 12 and the base plate 13 and other related structures can be accurately realized.

[0034] During actual operation, the brush 12 moves back and forth covering the air conditioner exhaust vent filter. This movement ensures that the brush 12 thoroughly cleans every area of ​​the air conditioner exhaust vent filter, removing all dust from the filter and collecting it in a timely manner through a dust collection device. Through this series of coordinated processes, the automatic cleaning operation of the air conditioner exhaust vent filter is perfectly completed, greatly improving cleaning efficiency and quality, and providing a reliable guarantee for air purification in the cigarette factory workshop.

[0035] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
