Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and in particular relates to a dust removal device for central air conditioning systems. Background Technology

[0002] With the improvement of living standards, central air conditioning is not only found in office buildings, but is also increasingly entering ordinary homes. Central air conditioning is a device that uses a main unit to connect multiple terminal devices through air ducts or refrigerant pipes to control different rooms in order to achieve the purpose of indoor air conditioning. It is more comfortable and more energy-efficient.

[0003] The ducts inside central air conditioning systems have relatively small diameters, making traditional vacuum cleaners and other cleaning equipment poorly compatible with the duct's inner diameter. Furthermore, the actual installation of ducts often involves multiple bends, preventing the traditional vacuum cleaner hoses from smoothly entering the ducts that need cleaning. Cleaning cannot be completed in one step; it requires manual cleaning of the duct's inner walls with a brush before vacuuming out the dust, resulting in high cleaning costs, high labor intensity, and incomplete cleaning, causing secondary pollution. Summary of the Invention

[0004] The purpose of this utility model is to provide a dust removal device to solve the problems existing in the prior art, such as the small diameter of the air duct in the central air conditioning system, the poor adaptability of traditional vacuum cleaners, and the difficulty in cleaning the air duct.

[0056] refer to Figure 1 , Figure 2 To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0057] This utility model proposes a dust removal device, which includes a dust collection component, an adapter 100, a sealing component 130, and a cleaning component 400. The cleaning component 400 is used to extend into the air duct of the central air conditioning system to clean the dust on the inner wall of the air duct. The dust collection component is used to suck out the dust inside the air duct. The adapter 100 is used to connect the dust collection component and the cleaning component 400. A section of the adapter 100 serves as a connector for connecting to the air duct. The sealing component 130 is provided on the adapter 100 to seal between the adapter 100 and the air duct, preventing dust from being output from the gap between the adapter 100 and the air duct, thereby reducing secondary pollution.

[0058] The dust collection component specifically includes a motor assembly 310 and a dust collection pipe 200. The dust collection pipe 200 is connected to the input end of the motor assembly 310. When the motor assembly 310 is turned on, it generates suction to draw out the dust in the air duct through the dust collection pipe 200.

[0059] The adapter 100 is used to connect to the end of the duct. The adapter 100 has at least a first adapter section 110 and a second adapter section 120. The first adapter section 110 and the second adapter section 120 are arranged at an angle. Alternatively, depending on the actual duct layout requirements, the first adapter section 110 and the second adapter section 120 can also be arranged in a straight line.

[0060] In some embodiments of this application, the port of the air duct is horizontal. Correspondingly, for ease of operation, the first adapter section 110 and the second adapter section 120 are set vertically. In use, the first adapter section 110 is connected downward to the dust extraction pipe 200, and the second adapter section 120 is connected horizontally to the interface of the air duct.

[0061] The first adapter pipe section 110 and the second adapter pipe section 120 are internally connected. The suction pipe 200 is connected to the first adapter pipe section 110. The suction pipe 200 is connected to the air duct through the adapter 100. Under the suction of the motor assembly 310, the dust in the air duct is sucked out through the adapter 100 and the suction pipe 200.

[0062] The sealing element 130 is disposed on the outer wall of the second transfer pipe section 120. A through connection hole is formed in the middle position of the sealing element 130. It is sleeved on the outer wall of the second transfer pipe section 120 and fixedly connected to the second transfer pipe section 120.

[0063] A second adapter port is formed on the second adapter pipe section 120. The outer wall of the sealing member 130 has a tapered sealing surface 131 along the direction close to the second adapter port. When connecting, the second adapter port of the adapter 100 is inserted into the duct, and the sealing member 130 is inserted into the duct from the smaller end.

[0064] The smaller end of the sealing component 130 is defined as the first end, and the larger end is defined as the second end. The first end of the sealing component 130 is close to the second adapter. During connection, after the second adapter is inserted into the duct, the first end of the sealing component 130 is inserted into the duct. The connection port of the duct is located between the first end and the second end of the sealing component 130. The sealing component 130 is made of rubber, which seals the gap between the duct and the second adapter section 120 through its own good elasticity and media resistance.

[0065] The cleaning assembly 400 includes a cleaning tube 600 and a cleaning brush head 410 connected to the end of the cleaning tube 600. The cleaning tube 600 is a flexible tubular structure that connects to the cleaning brush head 410 and also increases its depth into the duct.

[0066] The cleaning line 600 is connected to the adapter 100, which provides a connection base for the cleaning line 600.

[0067] In some embodiments of this application, in order to achieve automated cleaning of the cleaning brush head 410 in the duct, a drive motor 420 is connected to the end of the cleaning conduit 600. The drive motor 420 is a small motor structure, and its size is smaller than the inner diameter of the duct, so that the drive motor 420 extends into the duct along with the cleaning brush head 410.

[0068] The cleaning brush head 410 is connected to the output end of the drive motor 420. For example, but not limited to, at least two cleaning brush heads 410 are arranged at intervals along the output shaft of the drive motor 420. When the drive motor 420 is turned on, the output end rotates, which drives the cleaning brush head 410 to rotate and clean the inner wall of the air duct.

[0069] refer to Figure 3 The cleaning brush head 410 includes a cleaning bar 411 and bristles 412 formed around the cleaning bar 411. When the drive motor 420 is working, the bristles 412 continuously contact the inner wall of the air duct and brush off the dust on the inner wall of the air duct.

[0070] In other words, the cleaning brush head 410 rotates inside the duct under the action of the drive motor 420 to achieve all-round cleaning of the inner wall of the duct, and the cleaning cable 600 is a flexible hose structure that can bend according to the layout of the duct to allow the cleaning component 400 to penetrate into the duct to a certain depth, thereby increasing the cleaning range.

[0071] A power cord is installed inside the cleaning line 600, and the power cord is connected to an external power supply unit 500 to supply power to the drive motor 420.

[0072] In some embodiments of this application, since the first adapter pipe and the second adapter pipe are arranged vertically, a through wiring hole 142 is provided at the bend position of the adapter 100. The other end of the cleaning pipe 600 is connected to the wiring hole 142, or passes through the wiring hole 142 to the outside of the adapter 100, so as to facilitate the connection of the external power supply 500.

[0073] In some embodiments of this application, a camera 430 is also provided on the drive motor 420. The camera 430 is specifically located at the front end of the drive motor 420, and in order to avoid interference with the cleaning brush head 410, the camera 430 is located on the front side of the cleaning brush head 410.

[0074] The drive motor 420 is a small motor, and the camera 430 is a miniature camera. During use, the drive motor 420 rotates, which drives the cleaning brush head 410 to rotate, sweeping away the dust on the inner wall of the air duct. The miniature camera is used to observe the condition of the inner wall of the duct, thus achieving effective cleaning.

[0075] The camera 430 connects to the display screen via wired or wireless means.

[0076] When the camera 430 is connected to the display screen via a signal cable, the signal cable is also connected inside the cleaning cable conduit 600 to prevent dust from getting on the outside of the signal cable.

[0077] In addition to supporting the cleaning brush head 410 and the drive motor 420, the cleaning cable 600 also protects the power cable and signal cable.

[0078] During cleaning, the cleaning component 400 extends into the duct. As the cleaning component 400 goes deeper, the camera 430 transmits the image inside the duct to the display screen in real time for the operator to observe. When the cleaning brush head 410 reaches the cleaning position inside the duct, the drive motor 420 is turned on to clean the inner wall of the duct at that position. As cleaning progresses, the operator can drag the cleaning hose 600 backward or push it forward to clean the dust in different parts of the duct.

[0079] In summary, the camera 430 allows the operator to easily observe the condition inside the duct and facilitates the delivery of the cleaning brush head 410 to the corresponding position.

[0080] In some embodiments of this application, in order to improve the safety and portability of the motor assembly 310, the motor assembly 310 is disposed in the housing, and the housing is provided with an exhaust port for discharging the airflow output from the motor assembly 310.

[0081] To prevent foreign objects from entering the casing, a grille is installed on the exhaust vent.

[0082] Refer again Figure 1 A dust collection component 320 is also provided between the suction pipe 200 and the motor assembly 310. The dust collection component 320 is used to collect the dust output from the suction pipe 200.

[0083] The connection between the dust collection component 320, the motor assembly 310, and the suction pipe 200 is existing technology and is not the focus of this application, so it will not be described in detail here.

[0084] Dust inside the duct is collected in the dust collection unit 320 by the airflow through the second adapter pipe section 120, the first adapter pipe section 110, and the suction pipe 200, making it convenient to clean after cleaning.

[0085] In some embodiments of this application, the vacuum pipe 200 is a corrugated pipe structure. The corrugated pipe usually has an annular corrugated structure, which makes the corrugated pipe have both a certain rigidity and good flexibility, and it can extend or retract as the vacuuming distance changes during the vacuuming process.

[0086] The length of the 200mm corrugated suction pipe can be extended or shortened within a certain range according to actual needs. It has strong flexibility and bending resistance, and the corrugated pipe is lightweight, which makes it easy to transport and install, reducing labor and time costs.

[0087] In some embodiments of this application, a controller 510 is also included, which is used to facilitate the operator to control the vacuuming and cleaning process.

[0088] Specifically, the controller 510 is provided with a first operating unit and a second operating unit. The first operating unit is connected to the drive motor 420 through a first signal line. The first signal line is located inside the cleaning line tube 600. In order to provide complete protection for the first signal line, the cleaning line tube 600 is designed to extend to the controller 510 after passing through the wiring hole 142 of the adapter 100.

[0089] That is, the cleaning hose 600 specifically includes a first hose 610 and a second hose 620. The first hose 610 is located between the wiring hole 142 of the adapter 100 and the drive motor 420, and the second hose is located between the wiring hole 142 of the adapter 100 and the controller 510.

[0090] The second operating unit is connected to the motor assembly 310 via the second signal line and is used to control the switch of the motor assembly 310. In order to reduce the exposed wiring harness, the second signal line is designed to pass through the second conduit 620 from the wiring hole 142 to the adapter 100, then pass through the dust suction pipe 200, and finally connect to the motor assembly 310.

[0091] Of course, in addition to the connection path mentioned above, the second signal line can also be directly connected to the motor assembly 310.

[0092] In other words, the first operating unit is used to control the switch of the drive motor 420, and the second operating unit is used to control the switch of the motor assembly 310. The first and second operating units are integrated on the controller 510 for easy operation by the operator.

[0093] The controller 510 and the power supply unit 500 are both integrated into the housing 300, which helps to improve the safety of the equipment and makes it convenient to store and carry.

[0094] The dust removal device involved in this application can simultaneously perform cleaning and dust extraction on small-diameter PE ducts, shortening operation time and improving work efficiency.

[0095] Dust swept out of the duct is immediately sucked up by the dust collection component, avoiding secondary pollution of the air distribution box, heat exchanger, etc., which can effectively achieve rapid and efficient cleaning of small-diameter PE fresh air ducts.

[0096] In use, the cleaning component 400 is inserted into the duct to a certain depth, the second adapter section 120 of the adapter 100 is inserted into the connection end of the duct, and sealed by the sealing component 130.

[0097] As the cleaning component 400 moves deeper, the camera 430 transmits real-time images of the duct to the display screen for the operator to observe.

[0098] At the location in the duct to be cleaned, that is, the location with more dust, the drive motor is started by controlling the first operating unit to drive the cleaning brush head 410 to rotate and sweep away the dust. After a period of time, the motor assembly 310 is turned on by the second operating unit to suck out the dust in the duct and collect it through the dust collection component 320.

[0099] refer to Figures 4-7 In some embodiments of this application, the adapter 100 is further provided with a third adapter pipe section 140, which is on the same straight line as the second adapter pipe section 120. That is, the adapter 100 is a T-shaped structure as a whole, which is designed based on the traditional T-shaped component, which is conducive to reducing costs.

[0100] In other words, the first adapter section 110 on the adapter 100 is perpendicular to the second adapter section 120 and the third adapter section 140, and the adapter 100 as a whole has a three-way structure, which is convenient for processing.

[0101] In some embodiments of this application, the cleaning conduit 600 is connected to the housing 300 via a third transfer pipe section 140.

[0102] In some embodiments of this application, a cover 141 is provided on the third transfer pipe section, and a wiring hole 142 is provided on the cover 141, through which the cleaning pipe 600 passes.

[0103] The cover 141 is used to seal the third transfer pipe section 140, and the wiring hole 142 is used to facilitate the passage of cleaning lines.

[0104] refer to Figures 8-10 In some embodiments of this application, a filler 150 is provided in the third transfer pipe section 140, and a guide surface 151 is formed on the side of the filler 150 facing the second transfer pipe section 120. The guide surface 151 is used to guide the airflow in the second transfer pipe section 120 to the first transfer pipe section 110.

[0105] The air guide surface 151 is used to guide the dust input from the second transfer pipe section 120 into the first transfer pipe section 110, so as to prevent dust from accumulating in the third transfer pipe section 140.

[0106] During installation, first pass the cleaning conduit 600 through the wiring hole 142 on the cover 141. Then, pass the cleaning conduit 600 through the third adapter section 140 and out through the second adapter section 120. Next, insert the filler 150 into the third adapter section 140. At the same time, the cleaning conduit 600 is fixed in the adapter 100 by the filler 150. Finally, cover the third adapter section with the cover 141.

[0107] The dust removal device involved in this embodiment, except that the adapter 100 is a three-way structure including a third adapter pipe section 140, has the same structure for other components such as the dust suction assembly as in the other embodiments described above.

[0108] Specifically, the vacuuming assembly also includes a motor assembly 310 and a vacuuming pipe 200. When the motor assembly 310 is turned on, it generates suction to draw out the dust in the air duct through the vacuuming pipe 200.

[0109] A sealing element 130 is also provided on the outer wall of the second transfer pipe section 120. A through connection hole is formed in the middle of the sealing element 130. It is sleeved on the outer wall of the second transfer pipe section 120 and fixedly connected to the second transfer pipe section 120.

[0110] A second adapter port is formed on the second adapter pipe section 120. The outer wall of the sealing member 130 has a tapered sealing surface 131 along the direction close to the second adapter port. When connecting, the second adapter port of the adapter 100 is inserted into the duct, and the sealing member 130 is inserted into the duct from the smaller end.

[0111] The cleaning assembly 400 includes a cleaning tube 600 and a cleaning brush head 410 connected to the end of the cleaning tube 600. The cleaning tube 600 is a flexible tubular structure that connects to the cleaning brush head 410 and also increases its depth into the duct.

[0112] The end of the cleaning hose 600 is connected to a drive motor 420. The drive motor 420 is a small motor structure, and its size is smaller than the inner diameter of the air duct, so that the drive motor 420 extends into the air duct along with the cleaning brush head 410.

[0113] Multiple sweeping brush heads are spaced along the output shaft of the drive motor 420. When the drive motor 420 is turned on, the output end rotates, driving the sweeping brush head 410 to rotate, which will clean the inner wall of the air duct.

[0114] The cleaning brush head 410 includes a cleaning bar 411 and bristles 412 formed around the cleaning bar 411. When the drive motor 420 is working, the bristles 412 continuously contact the inner wall of the air duct and brush off the dust on the inner wall of the air duct.

[0115] Compared with the prior art, the advantages and positive effects of this utility model are:

[0116] This application designs a dust removal device for central air conditioning systems. The device combines a suction component and a cleaning component 400. The cleaning component 400 has a cleaning brush head 410 at the end of a cleaning conduit 600. The size of the cleaning brush head 410 is adapted to the inner diameter of the central air conditioning duct. Dust on the inner wall of the duct can be cleaned by the cleaning brush head 410. After cleaning by the cleaning brush head 410, the second adapter section 120, inserted into the duct, sucks the dust out through the suction component.
