Description

Technical Field

[0001] This utility model mainly relates to the field of duct cleaning brushes, specifically to a detachable air conditioning duct cleaning brush. Background Technology

[0002] Central air conditioning systems, household split air conditioners, and various ventilation ducts (HVAC systems) are widely used in modern buildings to provide people with a comfortable indoor environment.

[0003] During long-term operation, air conditioning ducts inevitably accumulate a large amount of dust, fibers, microorganisms (such as bacteria and mold spores), allergens (such as dust mite excrement), and even pollutants such as insect carcasses and construction debris.

[0004] These build-up deposits not only severely reduce the air delivery efficiency of air conditioning systems and increase energy consumption, but also become a secondary source of indoor air pollution, spreading germs and triggering allergic reactions (such as asthma and rhinitis) and respiratory diseases, posing a significant threat to the health of users. Therefore, regular and effective cleaning of air conditioning ducts is a key step in ensuring indoor air quality and efficient system operation.

[0005] During the operation of specific embodiments, the inventors discovered the following defects:

[0006] Brush heads are consumable parts, especially when cleaning metal ducts or encountering stubborn dirt, they wear out very quickly. Traditional brush heads and handles are often fixedly connected (such as by welding, strong adhesive, or one-piece molding). Once the bristles wear out, break, or the brush head structure is damaged, the entire cleaning tool becomes unusable or its performance drops significantly, resulting in resource waste and increased operating costs.

[0007] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0008] 1. The technical problem to be solved by the utility model:

[0009] This invention provides a detachable air conditioning duct cleaning brush to solve the technical problems existing in the background art.

[0010] 2. Technical Solution:

[0011] To achieve the above objectives, the technical solution provided by this utility model is as follows: a detachable air conditioning duct cleaning brush, including a guide structure, an unfolding structure slidably connected to the top and bottom of the guide structure, and a cleaning structure provided between the two unfolding structures;

[0012] The cleaning structure includes a moving strip and a positioning strip. A retaining strip is provided on one side of the positioning strip, and a side plate is provided on the other side of the positioning strip. A cleaning brush body is provided on the outer wall of the side plate.

[0013] Furthermore, the guide structure includes a guide rod, with guide grooves provided at the top and bottom of both sides of the outer wall of the guide rod, a handle provided at the top of the guide rod, and a partition plate provided in the middle of the guide rod.

[0014] Furthermore, the unfolding structure includes a sliding ring, with guide strips provided on both sides of the inner wall of the sliding ring. The sliding ring is slidably connected to a guide rod, and the guide strips are slidably connected to a guide groove.

[0015] Furthermore, a return spring is provided between the sliding ring and the spacer plate, and a rotating rod is provided on the outer wall of the sliding ring. The rotating rod is rotatably connected to the sliding ring, and the number of rotating rods is set to multiple.

[0016] Furthermore, the two ends of the moving strip are rotatably connected to the rotating rod, a positioning block is provided in the middle of the moving strip, a connecting pipe is provided on one side of the positioning block, and the positioning block is engaged with the locking strip.

[0017] 3. Beneficial effects:

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] This utility model utilizes the interaction between the internal positioning block and the locking strip of the movable strip. When it is necessary to replace the outer cleaning brush body, the cleaning brush body can be quickly separated simply by separating the positioning block and the locking strip. The unused cleaning brush body can then be installed between the positioning blocks.

[0020] After inserting the cleaning brush into the duct, release the brush. The return spring pushes the sliding mechanism outward, and then the sliding ring pushes the rotating rod to rotate. The rotating rod pushes the outer cleaning structure outward, so that the cleaning structure fits against the outer wall of the duct. Then, simply install the extension rod on one side of the handle and rotate it to make the cleaning structure rotate, thereby cleaning the inner wall of the duct. Attached Figure Description

When it is necessary to clean the air duct of the air conditioner, the retaining strip 305 on one side of the positioning strip 304 is connected to the positioning block 302, and the water pipe is connected to the connecting pipe 303. The connecting pipe 303 passes through the positioning block 302 and is connected to the side plate 306. The water in the water pipe can be discharged through the opening on one side of the cleaning brush body 307 and come into contact with the air duct.

[0034] Furthermore, the guide structure 1 includes a guide rod 101, with guide grooves 104 on the top and bottom of both sides of the outer wall of the guide rod 101. A handle 102 is provided on the top of the guide rod 101, and a partition plate 103 is provided in the middle of the guide rod 101. One end of the handle 102 is provided with an inner bolt hole for connecting with an extension tube, so that the extension tube can drive the guide structure 1 to extend into the inner wall of the air duct. Then, by rotating the extension tube, the extension tube drives the cleaning brush body 307 to rotate and clean its interior.

[0035] Furthermore, the unfolding structure 2 includes a sliding ring 201, with guide strips 202 on both sides of the inner wall of the sliding ring 201. The sliding ring 201 is slidably connected to the guide rod 101, and the guide strips 202 are slidably connected to the guide groove 104. A return spring 203 is provided between the sliding ring 201 and the partition plate 103.
