Description

Technical Field

[0001] The invention relates to the technical field of filter screen cleaning, and more specifically, to a cleaning device for an air conditioning filter screen. Background Art

[0002] When the air conditioner is running for a long time, the filter will filter the air. After long-term use, a lot of dust will accumulate inside, breeding bacteria, mold and other harmful substances. There are many air conditioners in commercial air conditioning systems, factories and central kitchens. When the above places are running, there will be a lot of dust, grease and other dirt, which will quickly clog the air conditioner filter. When the filter is clogged, the heating and cooling effects of the air conditioner gradually become inefficient. There is too much dust inside, which hinders the normal operation of the air conditioner and affects the cooling and heating effects of the air conditioner; this will not only endanger human health, but also increase energy consumption and shorten the service life of the air conditioner.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0030] Example 1

[0031] Reference Figure 1-Figure 6 As shown, the present invention is a cleaning device for an air conditioning filter, comprising a brushing mechanism 30, the brushing mechanism 30 is used for preliminary brushing of the air conditioning filter, and removing stubborn stains and adhesions on the filter, especially grease or hardened dirt;

[0032] The scrubbing mechanism 30 includes a feed box 31, the bottom of which is connected to a discharge box 32, two feed rollers 33 are arranged in the feed box 31, and a feed port 34 for the air conditioning filter to vertically pass through is arranged between the two feed rollers 33, the two feed rollers 33 are rotatably installed in the feed box 31 through a rotating shaft 36, and the ends of the two rotating shafts 36 are fixedly sleeved with drive gears 35, and the two drive gears 35 are meshed with each other. A drive motor is arranged on one side of the feed box 31, and the output shaft of the drive motor is connected to one of the rotating shafts 36. The two drive gears 35 are arranged in a protective shell, and the rotating shaft 36 is driven to rotate by the drive motor, and the drive gear 35 at the end of the rotating shaft 36 meshes with another drive gear 35 to drive the other rotating shaft 36 to rotate, and the two rotating shafts 36 drive the two feed rollers 33 to rotate relative to each other, so that the air conditioning filter can vertically pass through the feed port 34 and fall into the discharge box 32;

[0033] Two brackets 304 are arranged in the lower material box 32, and a plurality of brush heads 305 are rotatably mounted on the two brackets 304, and bristles are evenly distributed on the brush heads 305. The brush heads 305 are driven by a power source. When the brush heads 305 rotate on the brackets 304, the bristles on the brush heads 305 are used to scrub both sides of the air conditioning filter screen dropped from the feeding roller 33 to remove stubborn stains and adhesions on the filter screen. The brush heads 305 on the two brackets 304 are symmetrically arranged, and a liquid placing groove 306 is arranged in the brackets 304. The liquid placing groove 306 is connected to the side wall of the lower material box 32 through a pipeline. The brackets 304 are provided with a plurality of liquid outlets connected to the liquid placing groove 306. Cleaning liquid is introduced into the pipeline on the side wall of the lower material box 32. When too much grease adheres to the surface of the filter screen, the cleaning liquid is sprayed onto the surface of the bristles along the liquid outlet, so that the grease on the surface of the filter screen is cleaned once by the cleaning liquid, thereby improving the cleaning effect and reducing the burden of subsequent ultrasonic cleaning. It is suitable for cleaning the air conditioning filter screen in the kitchen and other workplaces.

[0034] A discharge port 37 is provided on one side of the discharge box 32, and a guide slope 38 is provided on the side of the discharge box 32 facing the discharge port 37. The inclination angle of the guide slope 38 is set to 30-45 degrees, so that the air-conditioning filter can be discharged from the discharge port 37 along the guide slope 38 after brushing. Two limiting holes 39 are provided on the discharge box 32, and limiting wheels 301 are rotatably installed in the two limiting holes 39. The two limiting wheels 301 are connected by a transmission shaft. The two limiting wheels 301 are arranged on the discharge port 37 for fixing and releasing the air-conditioning filter. A transmission motor is provided on one side of the discharge box 32, and the output shaft of the transmission motor is fixedly connected to the transmission shaft. The transmission motor drives the transmission shaft to rotate, and then drives the two limiting wheels 301 to rotate. When the air-conditioning filter moves to the discharge port 37 through the guide slope 38, the limiting wheel 301 contacts the air-conditioning filter and drives the air-conditioning filter to move out of the discharge port 37. The air-conditioning filter is fixed while the filter is moved, which is convenient for subsequent flushing operations.

[0035] An air duct 303 is provided at the bottom of the lower material box 32, and the air duct 303 is connected to the blower box 21 at the bottom. By continuously inputting air into the lower material box 32, the dust and dirt accumulated on the guide slope 38 of the lower material box 32 are cleaned to prevent the filter screen from continuing to be contaminated with dirt during movement after being brushed.

[0036] Flushing mechanism 20, which is arranged at the bottom of brushing mechanism 30, and flushes the filter screen twice through airflow; using airflow for cleaning can quickly blow away loose dust and small particles that are not completely removed, and reduce the interference of impurities during ultrasonic cleaning;

[0037] At this point, the filter screen has been cleaned of stubborn stains and most of the dust by the brushing mechanism 30, and the airflow cleaning can further clean the dust that cannot be directly removed by the brush;

[0038] The flushing mechanism 20 includes a blower box 21 and a flushing box 22. The blower box 21 transmits the generated wind force to the flushing box 22, and the filter screen is flushed through the flushing box 22. The blower box 21 and the flushing box 22 are installed at the bottom of the discharge box 32.

[0039] A rotating cover 23 is rotatably mounted on the flushing box 22. The rotating cover 23 is provided with a plurality of air outlets 24. A heating wire is provided inside the rotating cover 23. The heating wire can heat the air inside the rotating cover 23. The rotating cover 23 is connected to the blower box 21 through an air pipe. Two rotating rods 25 are provided at the bottom of the rotating cover 23.

[0040] A fan 26 is arranged in the blower box 21. Rotating grooves 27 for the rotating rod 25 to pass through are opened on both sides of the blower box 21. By driving the rotating rod 25 to rotate, the rotating cover 23 is driven to rotate on the flushing box 22, so that the wind direction of the rotating cover 23 can be switched to different angles. The top of the blower box 21 is connected with the air duct 303 at the bottom of the discharge box 32. The air duct 303 can be used to clean the dust and dirt inside the discharge box 32 to maintain the cleanliness of the inside of the discharge box 32, so as to avoid the filter being re-sticked with dirt during movement, which affects subsequent cleaning.

[0041] Deep cleaning mechanism 10, which is arranged below flushing mechanism 20, uses ultrasonic waves to deeply clean the filter, and uses the vibration effect of high-frequency sound waves to clean the tiny stains on the surface of the air conditioner filter and in its gaps. The cavitation effect generated by vibration can effectively remove fine particles, grease residues and stubborn micro-pollution on the filter. Ultrasonic cleaning can focus more on removing tiny pollutants to achieve the best cleaning effect;

[0042] The deep cleaning mechanism 10 includes an ultrasonic cleaning machine 11, which uses the oscillation effect of high-frequency sound waves to clean the tiny stains on the surface of the air conditioner filter and in the gaps therein. A loading frame 12 is provided on the ultrasonic cleaning machine 11, and a moving seat 13 is provided on one side of the loading frame 12. The moving seat 13 drives the loading frame 12 to rise and fall, thereby realizing the cleaning and drying operation of the filter; two guide rods 14 are provided on one side of the loading frame 12, and the two guide rods 14 are movably connected to the two rotating rods 25 respectively, and the loading frame 12 is provided with a movable seat 13. When 12 moves upward, the filter in the loading frame 12 moves out of the ultrasonic cleaning machine 11, and at the same time, the two guide rods 14 abut against the rotating rod 25, so that the rotating cover 23 rotates on the flushing box 22, so that the air outlet 24 of the rotating cover 23 faces the loading frame 12, and the fan 26 transports air into the rotating cover 23 and heats it with the electric heating wire to dry the filter in the loading frame 12. The air in the rotating cover 23 is generally heated to 40-60°C, which will not affect the overheating of the filter and cause changes in the filter material.

[0043] A lifting mechanism 40, which is disposed on one side of the deep cleaning mechanism 10 and is used to move the loading frame 12 between different mechanisms to achieve cleaning and drying of the filter screen in the loading frame 12;

[0044] The lifting mechanism 40 includes a lifting seat 42, on which a lifting screw 43 is rotatably installed. The moving seat 13 is threadedly connected to the lifting screw 43. The lifting screw 43 rotates to drive the moving seat 13 to move up and down, thereby realizing the movement of the loading frame 12. A lifting motor is arranged on the top of the lifting seat 42, and the output shaft of the lifting motor is fixedly connected to the end of the lifting screw 43. The lifting seat 42 is installed on the fixed frame 41, and the loading box is installed on one side of the fixed frame 41.

[0045] Working principle:

[0046] The filter is put into the feed box 31, and the driving motor is used to drive the rotating shaft 36 to rotate. The driving gear 35 at the end of the rotating shaft 36 engages with another driving gear 35 to drive the other rotating shaft 36 to rotate. The two rotating shafts 36 drive the two feed rollers 33 to rotate relative to each other, so that the air conditioning filter can vertically pass through the feed port 34 and fall into the discharge box 32 under the control of the two feed rollers 33;

[0047] As the filter screen continues to fall, due to the fixation of the two feeding rollers 33, the two brush heads 305 can scrub the surfaces of both sides of the filter screen. The scrubbed filter screen falls onto the guide slope 38 of the discharge box 32, and when it moves to the discharge port 37 through the guide slope 38, the limiting wheel 301 contacts the air conditioning filter screen and drives the air conditioning filter screen to move toward the outside of the discharge port 37, fixing the air conditioning filter screen while moving.

[0048] The blower box 21 delivers air to the rotating cover 23 of the flushing box 22, and blows the continuously falling filter screen through the air outlet 24 on the rotating cover 23 to remove loose dust and dirt on the filter screen caused by brushing, thereby reducing the interference of impurities caused by ultrasonic cleaning;

[0049] After being washed by the air flow, the filter falls onto the loading frame 12 of the ultrasonic cleaning machine 11. The ultrasonic cleaning machine 11 is used to perform ultrasonic cleaning on the filter in the loading frame 12 to remove fine particles, grease residues and stubborn micro-pollution on the filter. Since a large amount of dirt on the surface of the filter has been removed after the previous scrubbing and flushing, the ultrasonic cleaning time is greatly shortened, reducing damage to the filter and improving cleaning efficiency.

[0050] After ultrasonic cleaning is completed, the loading frame 12 is driven to rise by the lifting mechanism 40. When the loading frame 12 moves upward, the two guide rods 14 abut against the rotating rod 25 and drive the rotating rod 25 to rotate, thereby causing the rotating cover 23 to rotate on the flushing box 22, so that the air outlet 24 of the rotating cover 23 faces the loading frame 12, and the fan 26 transports air into the rotating cover 23. After heating by the electric heating wire, the filter in the loading frame 12 is dried, completing the integrated operation of brushing, flushing, ultrasonic cleaning and drying of the filter.
