Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, in particular to an automatic lifting spray disinfection and sterilization device for an air outlet and return air outlet of a central air conditioning. Background Art

[0002] In existing central air conditioning systems, the disinfection and cleaning of air outlets and return air outlets usually rely on manual operation. This traditional method is not only inefficient, but also inconvenient. Manual spraying of disinfectant often makes it difficult to ensure uniform distribution of disinfectant, which can easily cause disinfection dead corners, thus affecting the disinfection effect. In addition, the cleaning of the filter also relies on manual disassembly and cleaning, which not only increases the difficulty and time cost of operation, but may also cause damage to the filter due to improper operation.

[0003] With the advancement of science and technology and the development of automation technology, some central air conditioning cleaning equipment with a high degree of automation has appeared on the market. However, most of these equipment can only achieve a single cleaning or disinfection function, and the operation is complicated and the maintenance cost is high. Especially in terms of disinfection, many equipment still use static spraying, which cannot ensure the uniform distribution and comprehensive coverage of the disinfectant in the ventilation duct.

[0004] In view of the problems existing in the prior art, the present invention proposes an automatic lifting spray disinfection and sterilization device for the air outlet and return air outlet of a central air conditioner. The device combines a number of technologies such as servo motor drive, gear rack transmission, multi-duct spraying, and automatic filter cleaning to achieve automatic and efficient cleaning and disinfection of the air outlet and return air outlet.

[0005] The device of the present invention can not only significantly improve the disinfection effect, ensure full coverage and no dead corner disinfection inside the ventilation duct, but also clean the filter screen during the disinfection process, thereby improving the overall efficiency and air quality of the air conditioning system. In addition, the device of the present invention also has the advantages of simple operation and convenient maintenance, and has broad market application prospects. Summary of the invention

DETAILED DESCRIPTION Example

[0017] See also Figure 1-2, a central air-conditioning outlet return air outlet automatic lifting spray disinfection and sterilization device, comprising a ventilation duct 1, a servo motor 3 and a liquid storage tank 6, one end of the ventilation duct 1 is fixedly connected to a filter screen 2, the servo motor 3 is fixedly connected to the inner top wall of the ventilation duct 1, the driving end of the servo motor 3 is fixedly connected to a screw rod 4, the outer surface of the screw rod 4 is threadedly connected to a mounting plate 5, the liquid storage tank 6 is fixedly installed on the side wall of the mounting plate 5 away from the filter screen 2, and the liquid storage tank 6 is horizontally equidistantly rotated and installed with a plurality of first conduits 8 on the side wall close to the filter screen 2, the first conduit 8 passes through the mounting plate 5, and the end of the first conduit 8 away from the liquid storage tank 6 is connected with a second conduit 9, and the second conduit 9 is vertically equidistantly arranged with a spray pipe 10 on the side wall close to the filter screen 2, and the end of the second conduit 9 away from the first conduit 8 is fixedly connected to a driving rod 11, and the front and rear walls of the ventilation duct 1 are both provided with A movable plate 16 is arranged between the limiting groove 15, the filter screen 2 and the screw rod 4, the front and rear ends of the movable plate 16 are respectively slidably engaged with the two limiting grooves 15, a fixed groove 17 is provided on the side wall of the movable plate 16 away from the filter screen 2, and one end of the driving rod 11 close to the filter screen 2 is slidably engaged in the inside of the fixed groove 17, and a cleaning brush 18 is fixedly connected to the side wall of the movable plate 16 close to the filter screen 2, and the cleaning brush 18 contacts the side wall of the filter screen 2, and a plurality of fixed plates 12 are horizontally equidistantly arranged between the screw rod 4 and the movable plate 16, and the side walls of the plurality of fixed plates 12 are all provided with slots 13, and the inner front and rear walls of the slots 13 are fixedly connected with fixed racks 14, and a plurality of first conduits 8 respectively pass through the plurality of slots 13, and the plurality of first conduits 8 are all penetrated and fixedly connected with fixed gears 19, and the front and rear teeth of the fixed gear 19 are respectively meshed and connected with the two fixed racks 14.

[0018] The first conduit 8 and the second conduit 9 are arranged at a right angle, and this design helps to achieve a wider coverage of disinfectant spraying in the limited space of the ventilation duct 1. When the first conduit 8 rotates under the drive of the fixed gear 19 and the fixed rack 14, the second conduit 9 performs a circular motion, and the right-angle connection ensures that this motion can be converted into a wide coverage of the spray pipe 10 in three-dimensional space.

[0019] The telescopic conduit 7 installed at the bottom of the liquid storage tank 6 allows for convenient addition of disinfectant without disassembling the entire device. The telescopic function ensures that the conduit 7 can remain connected when the liquid storage tank 6 moves up and down, while avoiding interference with other parts of the ventilation duct 1.

[0020] The mounting plate 5 is fixed inside the ventilation duct 1 by means of sliding engagement. This design ensures that the mounting plate 5 can move up and down in the duct smoothly and facilitates the disassembly and maintenance of the device.

[0021] A plurality of fixing plates 12 are respectively fixed on the inner top wall and the inner bottom wall of the ventilation duct 1, providing stable support for the fixed rack 14. This design ensures that the first conduit 8 can achieve stable rotation through the engagement of the fixed gear 19 and the fixed rack 14 during the up and down movement.

[0022] The servo motor 3 is connected to the power supply through a line and is controlled by the control system. This design allows the user to set the parameters of the disinfection process, such as spraying speed, spraying amount, etc., as needed, thereby achieving accurate control of the disinfection process.

[0023] The working principle of the present invention is: when the automatic lifting spray disinfection and sterilization device for the air outlet and return air outlet of the central air conditioner is used, the servo motor 3 can drive the screw rod 4 to drive the mounting plate 5 to move up and down in the ventilation duct 1, and the mounting plate 5 can drive the first conduit 8 on the liquid storage tank 6 to move, and because the fixed gear 19 connected through the first conduit 8 on the liquid storage tank 6 is engaged with the fixed rack 14 in the slot 13 of the fixed plate 12, the first conduit 8 is moved up and down, and the fixed rack 14 can drive the fixed gear 19 to drive the first conduit 8 to rotate, so that the first conduit 8 can drive the multiple spray pipes 10 on the second conduit 9 to rotate in a circle and move up and down, and the disinfectant in the liquid storage tank 6 can be introduced into the spray pipe 10 through the first conduit 8 and the second conduit 9, so the spray pipe 10 can evenly spray the disinfectant into the ventilation duct 1. The disinfection surface formed by the spray pipes 10 on the second conduits 9 that rotate in a circle and move up and down can cover the inside of the ventilation duct 1. The retractable liquid guide pipe 7 can add disinfectant to the liquid storage tank 6. In addition, when the plurality of spray pipes 10 on the second conduit 9 rotate in a circle and move up and down, the driving rod 11 connected to the second conduit 9 also rotates in a circle and moves up and down, and the driving rod 11 slides and snaps into the fixing groove 17 of the movable plate 16, so that the driving rod 11 can drive the movable plate 16 to move up and down along the ventilation duct 1. Since the cleaning brush 18 on the movable plate 16 is in contact with the filter screen 2, the cleaning brush 18 on the movable plate 16 moves up and down to clean the filter screen 2.
