Description

Technical Field

[0001] This application belongs to the technical field of air-conditioning duct cleaning, and particularly relates to a central air-conditioning duct cleaning device. Background Art

[0002] Central air-conditioning refers to a large air-conditioning system, which consists of a host and indoor unit equipment. Different from ordinary household air-conditioning, central air-conditioning can be used in large-scale buildings. After the central air-conditioning ducts are used for a long time, dust and some impurities will accumulate, affecting the use of central air-conditioning.

[0003] The existing publication number is CN111318524B, which discloses a dust removal device for central air-conditioning air ducts, including a machine body. It is characterized in that: a camera is fixedly arranged at the left end of the machine body to facilitate workers to observe the environment inside the air duct, and a cleaning cavity with an opening facing downwards is arranged on the inner bottom wall of the machine body, and a swinging cleaning mechanism is arranged in the cleaning cavity.

[0004] Although the above-mentioned dust removal device for central air-conditioning air ducts realizes cleaning and dust suction at the same time and has a simple structure, its cleaning effect on the ducts is poor. The device cannot clean the dust and impurities adhered to the inner wall of the ducts, and the ducts cannot be effectively cleaned. Utility Model Content

[0005] The purpose of this application is to provide a central air-conditioning duct cleaning device for the above-mentioned existing technical problems. The device can effectively clean the dust and impurities adhered to the inner wall of the ducts, improve the cleaning effect of the device on the ducts, make the ducts cleaner after the cleaning is completed, and make it more difficult for dust and impurities to accumulate in the ducts.

[0006] This application provides a central air-conditioning duct cleaning device, including a machine body, and further includes:

[0007] A moving component, the moving component includes wheels and a crawler. Four rotatable wheels are arranged at the bottom end of the machine body, and the front and rear corresponding wheels are connected by a crawler;

[0008] A cleaning component, the cleaning component is installed on the machine body;

[0009] A mounting block, the mounting block is installed on the machine body;

[0010] Among them, one cleaning component is provided on each of the four side surfaces of the mounting block. The cleaning component includes a support base, a rotating shaft, a cleaning plate, a telescopic rod, a top block, a compression spring, and a scraping strip. The mounting block is installed on the machine body, the support base is installed on the mounting block, the rotating shaft is installed on the support base, the cleaning plate is installed on the rotating shaft, one end of the telescopic rod is installed on the mounting block, the top block is installed on the output end of the telescopic rod, the upper end of the top block abuts against the cleaning plate, one end of the compression spring is installed on the mounting block, the other end is installed on the top block, and the compression spring is sleeved on the telescopic rod. The scraping strip is installed on the cleaning plate, and several scraping strips are provided.

[0011] When it is necessary to clean the inner wall of the pipeline, the cleaning device is placed into the pipeline. A driving cavity is provided in the machine body, and a battery, a driving device, and a control board are provided in the driving cavity. At this time, the driving device in the driving cavity drives the wheels to rotate, and the wheels drive the crawler to rotate to drive the cleaning device to move in the pipeline. The displacement of the cleaning device drives the displacement of the cleaning plate that abuts against the inner wall of the pipeline. At this time, the scraping strips on the cleaning plate can scrape off the dust and impurities adhering to the inner wall of the pipeline. When it is necessary to place the cleaning device in the air outlet pipeline, the front ends of the four cleaning plates on the mounting block are abutted into the inner wall of the pipeline, and then the cleaning device is pushed into the pipeline until the entire cleaning device is pushed into the pipeline. At this time, the rear end of the cleaning plate is pressed down to abut against the inner wall of the pipeline. The rear end of the cleaning plate is pressed down to abut against the top block, and the top block is pressed down to drive the output end of the telescopic rod to retract and descend. At this time, the compression spring is compressed, and the force generated by the compression of the compression spring to reset and rebound presses the cleaning plate against the inner wall of the pipeline, so that the contact between the cleaning plate and the inner wall of the pipeline makes the scraping effect of the scraping plate on the dust and impurities adhering to the inner wall of the pipeline better.

[0012] Further, the cleaning component further includes:

[0013] A water spraying groove, which is arranged on the cleaning plate;

[0014] A water storage cavity, which is arranged in the mounting block;

[0015] A pressing pump, which is connected between the water spraying groove and the water storage cavity.

[0016] After the cleaning device is pushed into the pipeline and the rear end of the cleaning plate is pressed down, the cleaning plate squeezes the pressing pump. At this time, the pressing pump can pump out the water in the water storage cavity and spray it out from the water spraying groove to clean the inner wall of the pipeline, so that the impurities and dust adhering to the inner wall of the pipeline can be more easily cleaned.

[0017] Further, the cleaning component further includes:

[0018] A dust suction port, which is arranged on the mounting block;

[0019] A dust suction hose, which is installed on the dust suction port;

[0020] A vacuum cleaner, which is installed on the dust suction hose;

[0021] A power supply, which is installed in the mounting block.

[0022] When the scraper scrapes off the dust and impurities adhering to the inner wall of the pipeline during the displacement of the cleaning device, the scraped-off dust and impurities are likely to remain and accumulate in the pipeline and cannot be cleaned. At this time, the power supply drives the vacuum cleaner to start working, sucking the dust and impurities from the dust suction port into the dust suction hose, so that the scraped-off dust and impurities are not easily accumulated in the pipeline, making the cleaning effect of the cleaning device on the pipeline better.

[0023] Furthermore, the cleaning assembly further includes:

[0024] A dust storage chamber, which is arranged in the mounting block.

[0025] Since the cleaning assembly further includes a dust storage chamber which is arranged in the mounting block, when the dust and impurities are sucked into the dust suction hose by the vacuum cleaner, they will be uniformly received in the dust storage chamber. The fact that the dust and impurities are uniformly received in the dust storage chamber makes it more convenient and efficient for subsequent users to handle, reducing the labor intensity of the users.

[0026] Furthermore, the cleaning assembly further includes:

[0027] A brush, which is installed on the mounting block.

[0028] Since the cleaning assembly further includes a brush which is installed on the mounting block, after the scraper scrapes off the dust and impurities adhering to the inner wall of the pipeline, some dust and impurities still adhere to the inner wall and cannot be scraped off. After being washed by the water sprayed from the water spraying tank, when the cleaning device is driven to move forward continuously, the brush will brush the inner wall of the pipeline, so that the dust and impurities that cannot be scraped off by the scraper are brushed off, making the cleaning effect of the cleaning device on the inner wall of the pipeline better.

[0029] Furthermore, the following are installed on the mounting block:

[0030] A camera, which is installed on the mounting block;

[0031] A lighting lamp, which is installed on the mounting block, and a plurality of lighting lamps are provided.

[0032] A camera and a lighting lamp are installed on the installation block. The camera is installed on the installation block, and the lighting lamp is installed on the installation block. There are several lighting lamps. The camera faces the inside of the pipeline. The user can observe the situation inside the pipeline through the camera to operate the cleaning device, and the lighting lamp can provide illumination so that the camera can smoothly observe the situation inside the pipeline.

[0033] The beneficial effects of this application are as follows:

[0034] 1. When the cleaning device needs to be placed in the air outlet pipeline, the front ends of the four cleaning plates on the installation block are pressed against the inner wall of the pipeline, and then the cleaning device is pushed into the pipeline until the entire cleaning device is pushed into the pipeline. At this time, the rear ends of the cleaning plates are pressed down to abut against the inner wall of the pipeline. The rear ends of the cleaning plates are pressed down to abut against the top block, and the top block is pressed down to drive the output end of the telescopic rod to retract and descend. At this time, the compression spring is compressed, and the force generated by the compression of the compression spring to reset and rebound abuts the cleaning plate against the inner wall of the pipeline, making the contact between the cleaning plate and the inner wall of the pipeline better for the scraper to scrape off the sticky dust and impurities on the inner wall of the pipeline;

[0035] 2. The cleaning plate squeezes the pressing pump. At this time, the pressing pump can pump the water in the water storage cavity and spray it out from the water spraying groove to clean the inner wall of the pipeline, making it easier to clean the impurities and dust adhering to the inner wall of the pipeline;

[0036] 3. The scraped-off dust and impurities are likely to remain and accumulate in the pipeline and cannot be cleaned. At this time, the vacuum cleaner is driven by the power supply to start working, and the dust and impurities are sucked into the dust suction hose from the dust suction port, making it not easy for the scraped-off dust and impurities to accumulate in the pipeline, and making the cleaning effect of the cleaning device on the pipeline better.
