Abstract
Description
Technical Field
[0001] This utility model relates to the field of central air conditioning maintenance technology, and in particular to a cleaning device for central air conditioning maintenance. Background Technology
[0002] In central air conditioning systems, the filter is a crucial air filtration component, and its cleanliness directly affects the operating efficiency of the air conditioner and indoor air quality. Therefore, manual cleaning is frequently required during maintenance. However, in actual use, central air conditioning filters easily attract dust, hair, and various impurities. Over time, these contaminants can severely clog the filter pores, hindering airflow and significantly reducing the cooling or heating effect of the air conditioner, while also substantially increasing energy consumption.
[0003] Currently, there are two main methods for cleaning central air conditioning filters. One is manual disassembly and cleaning. While this method can directly clean the filter, the process is cumbersome and requires a lot of manpower and time. Frequent manual disassembly can easily damage the filter and related components. Moreover, during disassembly and installation, operators may cause safety problems due to improper operation. In addition, manual cleaning is often difficult to achieve a thorough and meticulous result, easily missing some dirt in the corners of the filter, thus affecting the cleaning effect.
[0004] Another approach involves using simple cleaning devices. However, these devices are often limited in function, only able to clean one side of the filter and failing to achieve a thorough cleaning. For example, some devices can only clean the outside of the filter, leaving the inside untouched. Furthermore, these simple devices can easily release dust and other debris into the air during the cleaning process, polluting the surrounding environment and potentially allowing the air conditioner to re-inhale the dust, thus affecting indoor air quality.
[0005] In summary, existing methods and devices for cleaning central air conditioning filters have many shortcomings, and there is an urgent need for a more efficient, comprehensive, and convenient cleaning device to solve these problems. This utility model of a cleaning device for central air conditioning maintenance was developed and designed based on this background.
[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0026] Reference Figure 1-4 A cleaning device for central air conditioning maintenance includes a mounting frame 1, a filter screen 2, a housing 4, and a collection box 45. The filter screen 2 is fixedly installed in the mounting frame 1. Two mounting slots are provided on the inner side wall of the mounting frame 1, located on the upper and lower sides of the filter screen 2 and arranged in a U-shape. A strip plate 3 is slidably installed in the upper mounting slot. A cleaning brush 31 is fixedly installed on the bottom side of the strip plate 3 and contacts the top side of the filter screen 2. The cleaning brush 31 can be controlled to clean the top side of the filter screen 2 when the strip plate 3 slides laterally. The housing 4 is located in the lower mounting slot. A connecting frame 44 is fixedly installed at the bottom of the housing 4. The collection box 45 is detachably installed on the bottom side of the connecting frame 44.
[0027] The same rotating shaft 41 is rotatably installed on the inner walls of the front and rear sides of the housing 4. A cleaning roller 42 is fixedly installed on the rotating shaft 41. Multiple brushes arranged radially are fixedly installed on the outer side of the cleaning roller 42. The multiple brushes are adapted to the bottom side of the filter screen 2. When the housing 4 slides laterally along the mounting groove below, the brushes on the cleaning roller 42 can be controlled to clean the bottom side of the filter screen 2. The bottom inner wall of the housing 4 is arc-shaped. A cleaning plate 43 that is inclined downward is fixedly installed on one inner wall of the housing 4. Multiple parallel grating teeth are fixedly installed on the side of the cleaning plate 43 away from the inner wall of the housing 4. The multiple grating teeth are adapted to the multiple brushes. When the brushes pass through the grating teeth, the dust and other debris adhering to the brushes can be cleaned off, so that the dust and other debris can enter the collection box 45 after passing through the connecting frame 44.
[0028] Two toothed plates 47 arranged in parallel are fixedly installed in the mounting groove below. Both ends of the rotating shaft 41 extend to the outside of the housing 4 and are respectively fixedly fitted with gears 46. The two gears 46 mesh with the corresponding toothed plates 47. When the housing 4 moves laterally along the mounting groove below, the rotating shaft 41 can be controlled to drive the cleaning roller 42 to rotate, thereby improving the cleaning effect on the filter screen 2.
[0029] Four support blocks 401 are fixedly installed at the bottom of the housing 4. Two reciprocating screws 5 are rotatably installed in each of the two mounting slots. The four reciprocating screws 5 are arranged in parallel with each other. The two reciprocating screws 5 located at the bottom are threadedly connected to the two corresponding support blocks 401, and the two reciprocating screws 5 located at the top are threadedly connected to the strip plate 3. Two servo motors 51 are fixedly installed on the inner wall of one side of the mounting slot. The output shafts of the two servo motors 51 are axially fixedly connected to the corresponding reciprocating screws 5, which can control the strip plate 3 and the housing 4 to move laterally back and forth along the mounting slot when the reciprocating screws 5 rotate. Synchronous pulleys 52 are fixedly sleeved on each of the four reciprocating screws 5. The same synchronous belt 53 is connected to the two synchronous pulleys 52 located on the same vertical axis, which can ensure the synchronicity of the rotation of the reciprocating screws 5.
[0030] In this embodiment, in order to prevent dust and other debris from escaping when the cleaning brush 31 and the brush clean the filter screen 2, L-shaped baffles are fixedly installed on both sides of the housing 4.
[0031] In this embodiment, the connection between the connecting frame and the collection box can be made by means of snap-fit or magnetic fixation, as long as it facilitates quick assembly and disassembly of the collection box and maintains good stability during operation.
[0032] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.
[0033] Working principle: In use, first connect the power supply and start the two servo motors 51. The two servo motors 51 work synchronously and control the two reciprocating screws 5 below to rotate synchronously. With the cooperation of the synchronous pulley 52 and the synchronous belt 53, the four reciprocating screws 5 can maintain synchronous rotation. The synchronous rotation of the two reciprocating screws 5 below, with the cooperation of the four support blocks 401, controls the housing 4 to move laterally and reciprocally stably along the mounting groove below. Due to the design of the gear 46 and the toothed plate 47, the shaft 41 of the housing 4 will rotate during the lateral reciprocating motion, thereby controlling the multiple brushes on the cleaning roller 42 to perform continuous cleaning operation from below the filter screen 2. The rotation of the cleaning roller 42 carries the dust and other debris into the housing 4. As the brush moves along with the cleaning roller 42, it passes through the grates on the cleaning plate 43, which removes the dust and other debris from the brush. This debris and dust will enter the collection box 45 after passing through the connecting frame 44. The synchronous rotation of the two reciprocating screws 5 above controls the strip plate 3 to move laterally back and forth in the mounting groove above, thereby controlling the cleaning brush 31 to clean the top side of the filter screen 2. Since the air intake direction is from bottom to top, there is less dust on the top of the filter screen 2. The purpose of using the cleaning brush 31 to clean the top side of the filter screen 2 is to work with the brush to achieve a thorough cleaning of the filter screen 2.
[0034] After cleaning, adjust the strip plate 3 and the housing 4 so that the mounting groove is located on the inner wall of both sides of the mounting frame 1, so that the cleaning brush 31 and the bristle brush can be disengaged from the filter screen 2, and the strip plate 3, cleaning brush 31 and bristle brush and housing 4 can be stored to avoid affecting the normal filtering work of the filter screen 2.

Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
