technical field

The invention relates to the technical field of dust cleaning, in particular to a portable dust cleaning machine.

Background technique

The power equipment is installed outdoors for many years, and the external dust will stick to the protective shell of the power equipment. If it is not treated for a long time, the dust will seep into the inside of the equipment, causing the dust to come into contact with the current, and there is a possibility of short circuit or explosion. Therefore, it is necessary to use Dust sweepers, and some electrical equipment are installed at high places. If you carry a relatively heavy dust sweeper, it will test the strength of the staff and it is inconvenient to operate. At this time, you need a portable dust sweeper;

At present, the portable dust cleaning machines on the market basically adopt the pistol type. The staff grasps the dust cleaning machine from the bottom, and it is close to the area where the power equipment needs to be cleaned. It is light in weight and convenient for the staff to operate manually. It is mainly divided into cleaning and vacuuming. The cleaning is to remove the dust by moving the cleaning brush, and the dust is mainly inhaled by the fan. According to different usage scenarios, the cleaning method of the portable dust sweeper will also be different;

However, the portable dust cleaners on the market still have the following problems: the portable dust cleaners on the market have always used fixed chemical fiber dry cloth to clean the power equipment shell during the cleaning process.

Working principle: When using the portable dust cleaning machine, the staff first holds the handle 2, and sticks the cleaning part on the left side of the protective shell 1 to the electric equipment shell. The chemical fiber dry cloth 10 is made of soft material and has certain Elasticity, a push-out mechanism 11 is set inside the chemical fiber dry cloth 10 in the cleaning area to ensure that the chemical fiber dry cloth 10 in the cleaning area is attached to the electrical equipment. The inner side of the dry cloth 10 is provided with a telescopic mechanism 9. When the chemical fiber dry cloth 10 moves to the cleaning area, the moving rod 901 is elongated, and the spring 902 is elongated. Groove 903 and spring 902 are in the initial state without extrusion force. When the chemical fiber dry cloth 10 in this area is cleaned to the point where the surface is covered with dust and the area of chemical fiber dry cloth 10 needs to be replaced, the motor 3 is started, and the motor 3 drives the cam 4 through the output shaft. Rotate, the output shaft is located at the bottom position of the cam 4, and the upper end of the cam 4 is provided with a linkage rod 501, which is hingedly connected with the linkage rod 501. At this time, the linkage rod 501 is driven to move to the right. At the same time, the upward rotation of the cam 4 Let the protruding area push the movable wheel 1201 to move upwards. The movable wheel 1201 and the rotating rod 1203 are in an integrated structure, and the center of the rotating rod 1203 is provided with a central axis 1202. At this time, the rotating rod 1203 rises due to the movable wheel 1201 on one side. When the other side of the rotating rod 1203 falls, the long rod 13 will not be fixed on the first gear 6, and the movement of the linkage rod 501 to the left will drive the rack 502 to move leftward. It meshes with the first gear 6, so the first gear 6 also starts to rotate, and the bottom of the first gear 6 is connected to the chemical fiber dry cloth 10 through the mounting seat 7. At this time, the chemical fiber dry cloth 10 will be rotated to remove the dirty chemical fiber. Change the position of the dry cloth 10 area to ensure that the chemical fiber dry cloth 10 in the working area is always clean. When the protruding part of the cam 4 rotates to the lower end, the long rod 13 will be raised. At this time, the protrusion 1302 on the long rod 13 is engaged with the Between the tooth blocks of the first gear 6, the rotation of the first gear 6 is limited, and the time for cleaning is given to the staff to realize intermittent rotation, which can always ensure that the working area of the chemical fiber dry cloth 10 is clean, and the dirty chemical fiber dry cloth 10 will be cleaned. Gradually rotate to the rear end. In order to facilitate the secondary use of the chemical fiber dry cloth 10 in this area, this cleaning machine can clean the chemical fiber dry cloth 10. The bottom of the cam 4 and the second gear 1401 rotate coaxially. Since the cam 4 is driven by the motor 3 Drive the rotation, so the second gear 1401 will also start to rotate, the second gear 1401 and the third gear 1402 mesh with each other, the rotation of the third gear 1402 drives the sprocket one 1501 to move, the sprocket one 1501 is externally meshed with the chain 1502, through the chain 1502 The sprocket wheel 2 1503 is driven to rotate. At this time, the chain 1502 is moving from left to right. A plurality of scrapers 16 are installed on the outside of the chain 1502. The moving direction of the scrapers 16 is the same as the rotation direction of the chemical fiber dry cloth 10, and the chemical fiber dry cloth 10 is in line with the scraper. plate 16 clings to, Therefore, the scraper 16 can scrape away the dust on the dirty chemical fiber dry cloth 10, clean the chemical fiber dry cloth 10 in time, reduce manual participation, and be more convenient and quick to clean. The scraper 16 that is stuck with dust moves to the collection box 17 side When using the fan inside the collection box 17, the dust on the scraper 16 is sucked into the collection box 17, which is convenient for unified treatment and reduces the chance of the staff contacting the dust. Due to the long-term friction of the chemical fiber dry cloth 10, damage may occur To replace the chemical fiber dry cloth 10 with a new one, first break off the Velcro of the interface of the chemical fiber dry cloth 10, then pull out the ring block 8 that is stuck in the other half, and rotate it into two halves through the rotating shaft. At this time, the engaging rod 801 It will also break away from the hole 701 on the mounting base 7. At this time, the chemical fiber dry cloth 10 is pulled out and moved out of the protective shell 1 through the rotating shaft of the first gear 6 to complete the disassembly of the chemical fiber dry cloth 10. When it needs to be installed, reverse the operation above The steps are enough, and will not be described in detail here, and the content not described in detail in this specification belongs to the prior art known to those skilled in the art.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or perform equivalent replacements for some of the technical features. Within the spirit and principles of the present invention, any modifications, equivalent replacements, improvements, etc., shall be included in the protection scope of the present invention.
