Technical Field
[0001] This utility model relates to the field of central air conditioning technology, specifically a convenient cleaning and maintenance device for central air conditioning systems. Background Technology
[0002] Central air conditioning is an air conditioning system that centrally processes air and distributes it to multiple areas. It is widely used in large commercial buildings, industrial plants, public facilities, and high-end residences. Its core advantages lie in its high efficiency and energy saving, high space utilization, precise temperature control, and stable operation. After prolonged use, the filters of central air conditioning systems will accumulate dust, which will affect their performance and requires regular cleaning and maintenance.
[0003] The prior art, disclosed in CN220918455U, discloses a filter cleaning device for central air conditioning maintenance, relating to the field of air conditioning filter cleaning technology. It includes a cleaning tank with an installation mechanism on one side of its inner wall, a decontamination mechanism on one side of the installation mechanism, an adjustment mechanism on the side of the cleaning tank near the installation mechanism, and a cleaning mechanism on the side of the adjustment mechanism. When the surface of the cleaning cylinder is heavily soiled, the cleaning mechanism is moved to a suitable position, a water pump is started to spray water onto the surface of the cleaning cylinder, a waterproof motor is started, and cleaning blades scrape away the dirt on the surface of the cleaning cylinder, making cleaning the cylinder more convenient and improving the cleaning efficiency of the device. When the filter element needs cleaning, the waterproof motor and water pump are started, water is drawn in through the suction pipe and sprayed onto the filter element through the nozzle, the drive motor is started to move the moving block, and the hydraulic telescopic rod is started to push the installation plate, thereby further increasing the cleaning efficiency of the filter element.
[0004] While existing technologies can improve the cleaning efficiency of filter elements, the spraying equipment can only be moved and cannot be swung. As a single, movable spraying device, the spraying effect is still poor, and the cleaning process has certain limitations.
[0005] Therefore, we proposed a convenient cleaning and maintenance device for central air conditioning systems to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide a convenient cleaning and maintenance device for central air conditioning, so as to solve the problem mentioned in the background art that the spray equipment can only be moved and cannot be swung when in use. The spraying effect of the single movable spray equipment is still poor and the cleaning has certain limitations.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a convenient cleaning and maintenance device for central air conditioning, including a housing, a water tank for water supply fixedly connected to one side of the housing, and a motor fixedly connected to the other side of the housing, and a threaded rod rotatably connected to the output end of the motor, which is connected to the inside of the housing. A cleaning mechanism is provided on the outside of the threaded rod, and the cleaning mechanism achieves efficient cleaning of the central air conditioning filter element by moving the sliding plate it contains.
[0008] Furthermore, the outer side of the threaded rod is threadedly connected to an inner threaded sleeve, and a sliding plate is fixedly connected to the outer side of the inner threaded sleeve, with the lower end of the sliding plate slidably connected to the water tank.
[0009] Furthermore, a fixed shaft is fixedly connected to the center of the sliding plate, and a spray plate is rotatably connected to the outside of the fixed shaft and connected to the water tank through a connecting hose. A sliding plate is fixedly connected between the side of the spray plate and the sliding plate.
[0010] Furthermore, a fixing plate is fixedly connected to the inner side of the water tank, and a return spring is fixedly connected to the inner side of the fixing plate, and a limiting plate for clamping the air conditioning filter is fixedly connected to the outer side of the return spring.
[0011] Furthermore, the cleaning mechanism includes a toothed plate, which is fixedly connected inside the housing. A rotating shaft is rotatably connected to the sliding plate, and a gear is fixedly connected to the side of the rotating shaft near the inner wall of the housing. A wiping plate for wiping the air conditioning filter is fixedly connected to the side of the rotating shaft away from the inner wall of the housing.
[0012] Furthermore, the toothed plates mesh with the gears, and the tooth blocks on the left and right sides of the toothed plates face opposite directions. A swing plate is fixedly connected to the outer side of the rotating shaft.
[0013] Furthermore, the end side of the swing plate is arranged in an arc shape, and an abutment plate is fixedly connected to the inner end side of the water spray plate, and the inner side of the abutment plate is in contact with the arc-shaped end side of the swing plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. A limiting plate is installed. The user places the air conditioning filter between two sets of limiting plates. The air conditioning filter can move towards the corresponding fixed plate by resisting and squeezing the limiting plate with its own width. It also squeezes the return spring and causes elastic deformation. At the same time, the limiting plate has a tendency to move towards the air conditioning filter under the drive of the elastic reaction force of the return spring. At this time, the limiting plate can clamp and limit the air conditioning filter, which facilitates the subsequent cleaning operation.
[0016] 2. Start the motor. The motor can drive the threaded rod to rotate. When the threaded rod rotates, it can simultaneously drive the inner threaded sleeve to move through the threaded connection. The inner threaded sleeve drives the sliding plate to slide along the inside of the water tank, thereby driving the spray plate to move synchronously and spray the air conditioning filter to clean it, improve cleaning efficiency and avoid cleaning dead corners.
[0017] 3. When the sliding plate moves, it can drive the gear to move synchronously. When the gear meshes with the gear plate, it can drive the rotating shaft to rotate synchronously. When the rotating shaft rotates, the wiping plate will rotate synchronously. The rotating wiping plate can rotate and wipe the side of the air conditioning filter, improving the cleaning effect of the air conditioning filter.
[0018] 4. While the rotating shaft is rotating, it can simultaneously drive the swing plate to rotate. The rotating swing plate can press against the contact plate through its arc-shaped end side, thereby causing the contact plate to swing. After swinging, the contact plate can simultaneously drive the water spray plate to swing along the fixed axis, thereby realizing multi-angle spraying operation and further improving cleaning efficiency.
[0019] 5. When the arc-shaped end of the rotating swing plate does not abut against the pressing plate, the pressing plate is not under force. The water spray plate is reset under the elastic force of the torsion spring, which facilitates subsequent swinging. The torsion spring and the pressing plate work together to realize the reciprocating swing of the water spray plate, improve the spraying range of the water spray plate and improve the cleaning efficiency.

[0027] 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.
[0028] Example 1: As Figure 1 , Figure 2 and Figure 3 The present invention provides the following technical solution: a convenient cleaning and maintenance device for central air conditioning, which discloses a limiting plate 14, which can clamp and limit the air conditioning filter element: a water tank 1 for water supply is fixedly connected to the side of the housing 2, and a motor 3 is fixedly connected to the other side of the housing 2, and a threaded rod 4 that is rotatably connected to the output end of the motor 3 is fixedly connected to the inside of the housing 2; a fixing plate 13 is fixedly connected to the inner side of the water tank 1, and a return spring 15 is fixedly connected to the inner side of the fixing plate 13, and a limiting plate 14 for clamping the air conditioning filter element is fixedly connected to the outer side of the return spring 15.
[0029] With the limit plate 14 installed, the user places the air conditioning filter between the two sets of limit plates 14. The air conditioning filter moves towards the corresponding fixed plate 13 by resisting and squeezing the limit plate 14 with its own width, and squeezes the return spring 15 to undergo elastic deformation. At the same time, the limit plate 14 also tends to move towards the air conditioning filter under the drive of the elastic reaction force of the return spring 15. At this time, the limit plate 14 can clamp and limit the air conditioning filter, which facilitates the subsequent cleaning operation.
[0030] Example 2: Figure 2 , Figure 4 and Figure 5The technical solution shown is provided by the present utility model as follows: a convenient cleaning and maintenance device for central air conditioning, which discloses a cleaning mechanism to achieve efficient cleaning of the central air conditioning filter element: a cleaning mechanism is provided on the outer side of the threaded rod 4, and the cleaning mechanism achieves efficient cleaning of the central air conditioning filter element by moving the sliding plate 5 contained therein. The outer side of the threaded rod 4 is threadedly connected to an inner threaded sleeve 16, and the outer side of the inner threaded sleeve 16 is fixedly connected to a sliding plate 5. The lower end of the sliding plate 5 is slidably connected to the water tank 1. A fixed shaft 10 is fixedly connected to the center of the sliding plate 5, and a spray plate 11 is rotatably connected to the outer side of the fixed shaft 10 and is connected to the water tank 1 through a connecting hose. The side of the spray plate 11 is fixedly connected to the sliding plate 5.
[0031] When motor 3 is started, it drives threaded rod 4 to rotate. During rotation, threaded rod 4 simultaneously moves internal threaded sleeve 16 via threaded connection. Internal threaded sleeve 16 causes sliding plate 5 to slide within water tank 1, thus moving spray plate 11 synchronously to clean the air conditioning filter. Simultaneously, rotating shaft 8 drives oscillating plate 18 to rotate. The rotating oscillating plate 18 presses against contact plate 9 through its arc-shaped end, thereby causing the contact plate... The oscillating plate 9 swings, and the oscillating contact plate 9 can synchronously drive the spray plate 11 to swing along the fixed axis 10, thereby realizing multi-angle spraying operation and further improving cleaning efficiency. When the arc-shaped end of the rotating oscillating plate 18 does not press against the contact plate 9, the contact plate 9 is not under force. The spray plate 11 is reset under the drive of the elastic force of the torsion spring 12, which facilitates subsequent oscillation. The torsion spring 12 and the contact plate 9 cooperate to realize the reciprocating oscillation of the spray plate 11, increase the spraying range of the spray plate 11, and improve cleaning efficiency.

The cleaning mechanism includes a toothed plate 6, which is fixedly connected inside the housing 2. A rotating shaft 8 is rotatably connected to the sliding plate 5. A gear 7 is fixedly connected to the side of the rotating shaft 8 near the inner wall of the housing 2, and a wiping plate 17 for wiping the air conditioning filter is fixedly connected to the side of the rotating shaft 8 away from the inner wall of the housing 2. The cleaning mechanism includes a toothed plate 6, which is fixedly connected inside the housing 2. A rotating shaft 8 is rotatably connected to the sliding plate 5. A gear 7 is fixedly connected to the side of the rotating shaft 8 near the inner wall of the housing 2, and a wiping plate 17 for wiping the air conditioning filter is fixedly connected to the side of the rotating shaft 8 away from the inner wall of the housing 2. The end side of the swing plate 18 is arranged in an arc shape. An abutment plate 9 is fixedly connected to the inner end side of the water spray plate 11, and the inner side of the abutment plate 9 is in contact with the arc-shaped end side of the swing plate 18.
[0033] When the sliding plate 5 moves, it can drive the gear 7 to move synchronously. When the gear 7 meshes with the toothed plate 6, it can drive the rotating shaft 8 to rotate synchronously. When the rotating shaft 8 rotates, it can cause the wiping plate 17 to rotate synchronously. The rotating wiping plate 17 can rotate and wipe the side of the air conditioning filter, improving the cleaning effect of the air conditioning filter.
