Description

Technical Field

[0001] This utility model relates to the field of air conditioning maintenance technology, specifically to an air conditioning maintenance device. Background Technology

[0002] During long-term use, air conditioners accumulate a lot of dust, hair, and impurities on their internal filters. If not cleaned in time, this will not only reduce the air conditioner's ventilation efficiency and cooling / heating effect, but may also breed bacteria and affect indoor air quality. Therefore, regular maintenance of the filters is an important part of daily air conditioner maintenance.

[0003] Currently, various handheld filter cleaning tools have appeared on the market. Most of the existing cleaning tools have a simple brush head structure, mostly using a single rotating brush head that can only rotate in one direction. When cleaning, the friction force of the brush head on the dust on the filter surface is concentrated in one direction, which easily creates cleaning dead corners. Moreover, the dust swept off cannot be collected in time and is easily spread into the air during the cleaning process, causing secondary pollution. This not only affects the indoor environment but may also be inhaled by the operator, posing a health hazard.

[0004] To address the aforementioned problems, this utility model provides an air conditioning maintenance device. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide an air conditioner maintenance device, which features a cleaning disc and a cleaning ring rotating in opposite directions to reduce cleaning dead angles. Simultaneously, in conjunction with the suction effect of the suction port and the air extraction pipe, it can prevent the swept dust from spreading into the air.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an air conditioner maintenance device, comprising: A base, one end of which is fixedly equipped with a handle, and the other end is rotatably equipped with a cleaning component for cleaning dust on a filter screen. The cleaning component is provided with a suction port on the base around its periphery for sucking up the swept dust. The cleaning assembly is driven by a motor installed inside the base.

[0007] Preferably, the cleaning assembly includes: A cleaning disc, which is rotatably mounted on a base; A cleaning ring, which is sleeved on the outside of the cleaning disc and rotatably mounted on the base; The sweeping disc and the sweeping ring rotate in opposite directions.

[0008] Preferably, the base is provided with a slot adapted to the cleaning assembly, the cleaning disc and the cleaning ring are rotatably mounted inside the slot, the output shaft of the motor extends into the slot and drives the cleaning disc and the cleaning ring through the transmission part.

[0009] Preferably, the transmission unit includes: The main gear is fixedly mounted on the output shaft of the motor and is fixedly connected to the cleaning disc. The toothed ring is fixedly connected to the cleaning ring; The auxiliary gear is located between the main gear and the gear ring, and is rotatably mounted on the bottom side wall of the empty slot, and simultaneously meshes with the main gear and the gear ring.

[0010] Preferably, the base is a hollow structure, and an air extraction pipe connected to a negative pressure suction device in the outside is fixedly installed on the base. The suction port is connected to the air extraction pipe through the cavity inside the base.

[0011] Preferably, a rubber ring is fixedly installed around the outer periphery of the suction port and on the base.

[0012] Preferably, the end of the rubber ring furthest from the base is an outwardly flared opening.

[0013] Preferably, an elastic ring is fixedly installed at the opening of the suction port, and the elastic ring opens unidirectionally toward the inside of the suction port when air is drawn in.

[0014] Preferably, a fixing ring is fixedly sleeved on the outer side of the base near the suction port. The fixing ring is a hollow structure, and multiple atomizing nozzles are installed on the side of the fixing ring near the suction port. A water supply pipe is installed on the fixing ring.

[0015] Preferably, the end of the atomizing nozzle away from the fixing ring is inclined toward the axis of the base, and multiple atomizing nozzles are evenly distributed along the circumference of the base.

[0016] The beneficial effects of this utility model are as follows: This invention, through the arrangement of a cleaning disc, a cleaning ring, a motor, a main gear, a secondary gear, and a gear ring, enables the cleaning disc and the cleaning ring to rotate in opposite directions via the main gear, secondary gear, and gear ring, reducing cleaning dead angles. At the same time, in conjunction with the suction effect of the suction port and the suction pipe, the swept dust can be promptly removed from the filter surface, achieving efficient cleaning of the air conditioning filter and avoiding secondary pollution caused by dust residue.

[0017] This invention utilizes a fixed ring, an atomizing nozzle, a water supply pipe, a rubber ring, and an elastic ring. Water is supplied to the fixed ring via the water supply pipe and then sprayed through the atomizing nozzle towards the filter screen. This moistens the dust stirred up during cleaning, thus suppressing dust. The rubber ring enhances the seal between the base and the filter screen, while the elastic ring ensures unidirectional airflow from the suction port, improving suction efficiency. The atomized water also softens stubborn dirt on the filter screen surface, aiding in cleaning. This design achieves dust reduction during the cleaning process and enhances the ability to remove stubborn dirt. Attached Figure Description

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides an air conditioner maintenance device, such as... Figures 1 to 6 As shown.

[0028] Example 1: An air conditioner maintenance device includes a base 1, which is the main support component of the device. One end of the base 1 is fixedly installed with a handle (for easy handling by the operator), and the other end is rotatably installed with a cleaning component. The cleaning component is driven by a motor 6 installed inside the base 1 to clean the dust on the filter screen.

[0029] The cleaning assembly includes a cleaning disc 3 and a cleaning ring 4. Both the cleaning disc 3 and the cleaning ring 4 are rotatably installed inside the empty slot 5, and the cleaning ring 4 is sleeved on the outside of the cleaning disc 3 to form a double-layer cleaning structure. The cleaning disc 3 and the cleaning ring 4 rotate in opposite directions, which can reduce cleaning dead corners.

[0030] The output shaft of the motor 6 passes through the base 1 and extends into the interior of the empty groove 5, and drives the sweeping disc 3 and the sweeping ring 4 through the transmission unit. The transmission unit includes a main gear 7 and a gear ring 8. The main gear 7 is fixedly connected to both the output shaft of the motor 6 and the sweeping disc 3. The gear ring 8 is rotatably installed inside the empty groove 5 and is fixedly connected to the sweeping ring 4. A secondary gear 9 is rotatably installed on the bottom side wall of the empty groove 5. One side of the secondary gear 9 meshes with the main gear 7, and the other side meshes with the gear ring 8.

[0031] After the motor 6 starts, it drives the main gear 7 on the output shaft to rotate. The main gear 7 directly drives the cleaning disc 3 to rotate synchronously. At the same time, the main gear 7 drives the secondary gear 9 to rotate in the opposite direction through meshing. The secondary gear 9 then drives the gear ring 8 and the cleaning ring 4 fixed to it to rotate in the opposite direction through meshing. Since the cleaning disc 3 and the cleaning ring 4 rotate in opposite directions, they form a bidirectional frictional force on the dust on the filter screen surface, reducing the cleaning dead angles caused by rotation in one direction and achieving comprehensive cleaning of the filter screen.

[0032] Example 2: Based on Embodiment 1, in order to avoid dust diffusion, the base 1 is designed as a hollow structure, and a through cavity is formed inside it; a suction port 2 is provided at one end of the base 1 near the cleaning component and at the periphery of the cleaning component. An air extraction pipe 10 is also fixedly installed on the base 1. The air extraction pipe 10 is connected to an external negative pressure suction device (such as an industrial vacuum cleaner), and the suction port 2 is connected to the air extraction pipe 10 through the cavity inside the base 1.

[0033] A rubber ring 11 is fixedly installed on the base 1 around the outer periphery of the suction port 2. The rubber ring 11 has a certain elasticity. When the operator attaches the cleaning component to the filter screen, the rubber ring 11 will make close contact with the surface of the filter screen and fill the gap between the base 1 and the filter screen. The end of the rubber ring 11 away from the base 1 is designed as an outwardly flared open shape, which can make the rubber ring 11 deform in the direction away from the suction port 2 when subjected to pressure, so as to avoid blocking the suction port 2.

[0034] An elastic ring 13 is fixedly installed at the opening of the suction port 2. The elastic ring 13 is made of rubber and has good elastic deformation capability. When the external negative pressure suction device is started, a negative pressure is formed inside the suction port 2. Under the action of negative pressure, the elastic ring 13 opens unidirectionally towards the inside of the suction port 2, allowing the dust swept down by the cleaning component to smoothly enter the suction port 2. If the negative pressure device stops working, the elastic ring 13 returns to the closed state under its own elasticity, which can prevent the dust that has entered the cavity of the base 1 from flowing back from the suction port 2 to the filter surface or into the air, ensuring unidirectional flow of dust.

[0035] To improve the one-way sealing performance of the elastic ring 13, a retaining ring (such as a retaining ring) is fixedly installed below the elastic ring 13 and on the inner wall of the suction port 2. Figure 6 As shown, this can limit the deformation of the elastic ring 13 toward the outside of the suction port 2.

[0036] Example 3: Based on Embodiment 2, to further prevent dust diffusion, a fixing ring 12 is fixedly sleeved on the outer side of the base 1 near the suction port 2. The fixing ring 12 is a hollow structure, and multiple atomizing nozzles 15 are installed on the side near the suction port 2. The multiple atomizing nozzles 15 are evenly distributed around the circumference of the base 1 to ensure that the spray range covers the entire cleaning area. The hollow structure of the fixing ring 12 can store a certain amount of water to provide water reserves for the atomizing nozzles 15. The end of the atomizing nozzle 15 away from the fixing ring 12 is tilted towards the axis of the base 1. This tilt angle allows the atomized water sprayed by the atomizing nozzle 15 to act precisely on the contact area between the cleaning component and the filter screen, rather than spreading outward and wasting water resources. In addition, the spray on the filter screen can also soften stubborn dirt on the filter screen surface to assist in cleaning. A water supply pipe 14 is also installed on the fixing ring 12 to supply water to the inside of the fixing ring 12.

[0037] The motor 6 and the atomizing nozzle 15 are connected to an external power source via cables.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
