Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner cleaning equipment, in particular to a multi-connected central air conditioner cleaning device. Background Art

[0002] The multi-connected central air conditioner is a type of user central air conditioner, commonly known as "one drag many", which means that one outdoor unit is connected to two or more indoor units through pipes. The outdoor side adopts an air-cooled heat exchange form, and the indoor side adopts a direct evaporation heat exchange form of a primary refrigerant air conditioning system. After long-term use, cleaners are required to clean the air ducts.

[0003] For example, a multi-connected central air conditioner cleaning device with the authorization announcement number of "CN220611628U". Through a plurality of sets of cleaning components arranged, during the process of the walking mechanism driving the main body to move in the pipeline, a plurality of driving parts can drive a plurality of mounting blocks to rotate, so that the brush strips keep swinging around the axis direction of the mounting blocks, and the dust on the inner wall of the pipeline is slapped off. Under the suction of the dust collection box, the slapped dust is absorbed clean through the connecting hose, improving the cleaning range and cleaning effect. Through the telescopic structure arranged, it is ensured that the walking wheel assembly can always abut against the inner wall of the pipeline, ensuring the stability during the cleaning process and improving the practicability. However, for this multi-connected central air conditioner cleaning device, a plurality of brush strips are installed through the first hoop. Since the first hoop needs to be fixed by bolts, the bolts are prone to looseness after long-term slapping, resulting in poor dust slapping and cleaning effect of the brush strips, thus making the cleaning effect of the air duct poor. At the same time, for this multi-connected central air conditioner cleaning device, the height of the brush strips cannot be adjusted. When the pipeline to be cleaned is relatively thick, the pipeline cannot be cleaned, thus increasing the working limitations. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems that a plurality of brush strips are installed through the first hoop. Since the first hoop needs to be fixed by bolts, the bolts are prone to looseness after long-term slapping, resulting in poor dust slapping and cleaning effect of the brush strips, thus making the cleaning effect of the air duct poor. At the same time, for this multi-connected central air conditioner cleaning device, the height of the brush strips cannot be adjusted. When the pipeline to be cleaned is relatively thick, the pipeline cannot be cleaned, thus increasing the working limitations, and a multi-connected central air conditioner cleaning device is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a multi-connected central air-conditioning cleaning device, including a fixing plate and a turntable. An auxiliary fixing mechanism is provided on the left side of the fixing plate, and two adjusting mechanisms are provided on the right side of the turntable. Two vacuum cleaners are installed at the right end of the fixing plate. The suction ends of the vacuum cleaners are fixedly communicated with shunt pipes, and the ends of the shunt pipes are fixedly communicated with suction hoods. A plurality of brushes are provided on the right side of the fixing plate.

[0007] Preferably, the auxiliary fixing mechanism includes a first outer shell. The inner wall of the first outer shell is rotatably connected to a rotating handle through a bearing. The lower end of the rotating handle is fixedly connected to a double-headed screw. The lower end of the double-headed screw is rotatably connected to the first outer shell through a bearing. The outer wall of the double-headed screw is threadedly connected to a slide plate. The right ends of the slide plates are rotatably connected to rollers through rotating shafts. The outer walls of the rollers are in contact with the inner wall of the first outer shell. The outer walls of the slide plates are slidably connected to the first outer shell. The inner sides of the slide plates are fixedly connected with bumps.

[0008] Preferably, the right end of the first outer shell is fixedly connected to the fixing plate. A second motor is fixedly connected to the inner wall of the fixing plate. The end of the output shaft of the second motor is fixedly connected to a turntable.

[0009] Preferably, the adjusting mechanism includes a second outer shell. A first motor is fixedly connected to the inner wall of the second outer shell. The end of the output shaft of the first motor is fixedly connected to a worm. The right end of the worm is rotatably connected to a first fixing block through a bearing. The worm is meshed with a worm wheel. The rear ends of the transmission shafts of the worm wheels are rotatably connected to the second outer shell through bearings. The front ends of the transmission shafts of the worm wheels are fixedly connected to cylinders. The outer walls of the cylinders are slidably connected to swing rods. The left ends of the swing rods are movably connected to the second outer shell through pins. The inner walls of the swing rods are slidably connected to the protruding parts of the vertical rods. The outer walls of the vertical rods are slidably connected to the second fixing block and the second outer shell respectively. The outer walls of the second fixing block and the first fixing block are fixedly connected to the second outer shell.

[0010] Preferably, the left ends of the second outer shells are fixedly connected to the fixing plate. Brushes are fixedly connected to the ends of the vertical rods.

[0011] The beneficial effects of a multi-connected central air-conditioning cleaning device proposed by the present utility model are as follows: Through the cooperation of the fixing plate and the auxiliary fixing mechanism, the rotation of the rotating handle drives the rotation of the double-headed screw, thereby driving the synchronous movement of the two slide plates, further driving the synchronous movement of a plurality of bumps, and at the same time driving the synchronous rolling of the two rollers along the chutes processed on the inner wall of the second outer shell, so as to achieve that when working for a long time, the brushes are very stable and will not cause poor dust cleaning effect of the brushes, and the effect of the brushes cleaning the air duct is good.

[0012] Through the cooperation of the fixing plate and the adjusting mechanism, the rotation of the output shaft of the first motor drives the worm to rotate, which in turn drives the two worm wheels to rotate. The rotation of the two worm wheels drives the two cylinders to slide along the sliding grooves machined on the swing rod, thereby driving the swing rod to move. The swing of the swing rod drives the protruding part of the vertical rod to slide along the sliding groove machined on the swing rod, thereby driving the vertical rod to move, so as to realize the adjustment of the height of the brush. When the air duct to be cleaned is relatively thick, the pipeline can be cleaned, thus reducing the working limitations. Description of the Drawings

[0024] Refer to the attached Figure 3 and the attached Figure 5

[0025] The adjusting mechanism 6 includes a second housing 601. A first motor 602 is fixedly connected to the inner wall of the second housing 601. The first motor 602 is connected to the storage battery through a wire, and the storage battery provides power for the first motor 602. The end of the output shaft of the first motor 602 is fixedly connected to a worm 603. The right end of the worm 603 is rotatably connected to a first fixing block 604 through a bearing.

[0026] Working principle:

[0027] When cleaning the air ducts of a multi-connected central air conditioner:

[0028] Preparation process:

[0029] The operator places the outer wall of the pipeline robot between multiple bumps 206, and then the operator rotates the turning handle 202 clockwise. The rotation of the turning handle 202 drives the double-headed stud 203 to rotate, thereby driving the two sliding plates 205 to move inward synchronously, further driving the multiple bumps 206 to move inward synchronously, and at the same time driving the two rollers 204 to roll inward along the chutes machined on the inner wall of the second housing 201. When the outer walls of the multiple bumps 206 are all in close contact with the output end of the pipeline robot, stop rotating the turning handle 202. The brush 5 works more stably and the cleaning effect is better.

[0030] Cleaning process of the air ducts of a multi-connected central air conditioner:

[0031] The operator starts the power supply of the first motor 602. The output shaft of the first motor 602 rotates forward to drive the worm 603 to rotate, thereby driving the two worm wheels 605 to rotate. The rotation of the two worm wheels 605 drives the two cylinders 606 to slide along the chutes machined on the swing rod 607, thereby driving the swing rod 607 to move. The swing of the swing rod 607 drives the protruding part of the vertical rod 608 to slide along the chute machined on the swing rod 607, thereby driving the vertical rod 608 to move outward synchronously. The movement of the vertical rod 608 drives the brush 5 to move. When the bristles on the brush 5 are in contact with the inner wall of the multi-split air-conditioning duct, the power supply of the first motor 602 is turned off, so as to realize that the brush 5 can be adjusted to extend and retract synchronously outward, and clean multiple ducts of different models of multi-split air-conditioning. Then, the pipeline robot is started. The pipeline robot moves, and at the same time, the power supply of the second motor 8 is started (the start and stop of the pipeline robot and the second motor 8 are controlled by external remote control, so as to realize the operation of the multi-split air-conditioning). The rotation of the output shaft of the second motor 8 drives the turntable 9 to rotate, thereby driving the brush 5 to rotate along the inner wall of the duct to clean the multi-split air-conditioning duct. The power supply of the vacuum cleaner 3 is started. The vacuum cleaner 3 sucks the dust into the shunt pipe 4 through the dust suction hood 7 and conveys it into the vacuum cleaner 3. After the cleaning of the multi-split air-conditioning duct is completed, the operator can regularly clean the dust in the vacuum cleaner 3.
