Detailed Implementation
[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0030] Example 1:
[0031] Reference Figure 1-6 As shown, a soot blowing device suitable for automotive windshields includes a mounting box 100, a lifting mechanism 200 mounted at the bottom of the mounting box 100, a connecting beam 300 mounted at the upper end of the lifting mechanism 200, four soot blowing mechanisms 400 respectively mounted at the upper end of the connecting beam 300, and an air pump 500 installed inside the mounting box and connected to the four soot blowing mechanisms 400; wherein
[0032] The soot blowing mechanism 400 includes a first rotary motor 410 mounted on the connecting beam 300, a second rotary motor 430 connected to the first rotary motor 410, and a nozzle 450 connected to the second rotary motor 430.
[0033] The dust blowing device also includes a dust sensor 600 mounted above the windshield of the vehicle 800, and a controller 700 mounted in the mounting housing 100.
[0034] Reference Figure 6 As shown, the dust blowing device is installed on the hood of the car 800, located in front of the windshield wipers.
[0035] Preferably, the controller 700 is electrically connected to the first rotary motor 410, the second rotary motor 430, the air pump 500, the micro rotary motor 140, and the dust sensor 600. The vehicle 800 supplies power to the dust blowing device.
[0036] Preferred, refer to Figure 2 As shown, the mounting box 100 includes a mounting box body 110 and a mounting box cover 120 rotatably connected to the mounting box body 110; a rotating shaft 130 is mounted on the mounting box cover 120, and a miniature rotating motor 140 is mounted on the inner wall of the mounting box body 110 that is connected to the mounting box cover 120. The rotating shaft of the miniature rotating motor 140 is fixedly connected to the rotating shaft 130, and the other side of the rotating shaft 130 is rotatably connected to the inner wall of the mounting box body 110.
[0037] When it is necessary to start the soot blowing device, refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the controller 700 controls the micro motor to rotate, opens the mounting box cover 120, and then controls the lifting mechanism 200 to rise, pushing the dust blowing mechanism 400 out of the mounting box body 110, in preparation for cleaning the car 800.
[0038] Optionally, sealing strips 150 are installed around all four sides of the mounting cover 120. The sealing strips 150 around the four sides where the mounting cover 120 connects to the mounting box body 110 can prevent dust from entering the mounting box body 100 when the dust blowing device is not in use, protect the components inside the mounting box body 100, and increase the service life of the dust blowing device.
[0039] Preferably, the soot blowing mechanism 400 further includes a first motor base 420 mounted on the crossbeam and a second motor base 440 mounted on the output end of the first rotary motor 410. The arrangement of the first motor base 420 and the second motor base 440 facilitates the fixing of the first rotary motor 410 and the second rotary motor 430.
[0040] The position of the soot blowing mechanism 400 within the mounting housing 100 is as follows: Figure 3 As shown, this is the initial position of the soot blowing mechanism 400. After the soot blowing mechanism 400 is started, the first rotating motor 410 first rotates the nozzle 450 so that the nozzle 450 rotates out of the mounting box body 110. After that, the first rotating motor 410 controls the left and right rotation of the nozzle 450, and the second rotating motor 430 controls the nozzle 450 to adjust its up and down rotation in front of the windshield.
[0041] Preferably, there are two air pumps 500, one of which is connected to the nozzles 450 of the two soot blowing mechanisms 400. One air pump 500 corresponds to two nozzles 450, which can ensure the air source pressure and ensure stable soot blowing effect.
[0042] Preferably, the output end of the air pump 500 is a two-way pipe 510, and the two ports of the two-way pipe 510 are respectively connected to two nozzles 450 through connecting air pipes 520; a heating element 460 is also installed on the inner wall of the nozzle 450. By setting the heating element 460 in the nozzle 450, the heated air source can better clean the dust that adheres to the windshield in winter.
[0043] Both ports of the two-way pipe 510 are equipped with solenoid valves, which are electrically connected to the controller 700. By controlling the opening and closing of the solenoid valves through the controller 700, the corresponding nozzle 450 can be controlled to start or stop spraying air.
[0044] Preferably, two blowing mechanisms 400 are provided on each of the left and right sides of the crossbeam, and the blowing mechanisms 400 on both sides of the crossbeam are symmetrically arranged. The nozzles 450 are symmetrically arranged so that the two nozzles 450 in the middle can blow ash from the middle to both sides, so that there are no dead corners in the blowing process of the windshield.
[0045] Reference Figure 1 As shown, the working principle of nozzle 450 is as follows: Taking the direction facing the windshield as an example, the nozzle 450 located on the left side of the middle is rotated downward by a certain angle by the second rotating motor 430, and rotated to the right by a certain angle by the first rotating motor 410, so that nozzle 450 faces the bottom of the windshield, and the nozzle 450 is slightly raised on the side facing the windshield (the starting position of nozzle 450 when blowing ash is not perpendicular to the windshield, but forms an angle of 30-45° with the windshield). This is the starting position for operation. The nozzle 450 located on the right side of the middle is rotated downward by the second rotating motor 430. The nozzle 450 is rotated to the left by the first rotating motor 410, so that the nozzle 450 faces the bottom of the windshield and the nozzle 450 is slightly raised on the side facing the windshield (the starting position of the nozzle 450 when blowing dust is not perpendicular to the windshield, but forms an angle of 30-45° with the windshield). The nozzle 450 on the left side of the middle cleans the windshield from right to left (the vertical angle is adjusted along with the nozzle 450 during operation), and the nozzle 450 on the right side of the middle cleans the windshield from left to right (the vertical angle is adjusted along with the nozzle 450 during operation).
[0046] The nozzle 450 on the left is rotated downwards by a certain angle via the second rotating motor 430, and rotated to the right by a certain angle via the first rotating motor 410, so that the nozzle 450 faces the bottom of the windshield, and the nozzle 450 is slightly raised towards the side facing the windshield (the initial position of the nozzle 450 when blowing ash is not perpendicular to the windshield, but forms an angle of 30-45° with the windshield) as the working starting position. The nozzle 450 on the right is rotated downwards by a certain angle via the second rotating motor 430, and rotated to the right by a certain angle via the first rotating motor 410. The motor 410 rotates the nozzle 450 to the left by a certain angle, so that the nozzle 450 faces the bottom of the windshield, and the nozzle 450 is slightly raised on the side facing the windshield (the starting position of the nozzle 450 when blowing ash is not perpendicular to the windshield, but forms an angle of 30-45° with the windshield). The left nozzle 450 cleans the windshield from right to left (the vertical angle is adjusted along with the nozzle 450 during operation), and the right nozzle 450 cleans the windshield from left to right (the vertical angle is adjusted along with the nozzle 450 during operation).
[0047] The controller 700 controls the two middle air-blowing mechanisms to blow air through the opening and closing of solenoid valves. Specifically, it controls the two middle nozzles 450 to first blow dust from the windshield. After the second rotating motor 430 of the two middle nozzles 450 rotates 90°, the controller 700 activates the solenoid valves corresponding to the nozzles 450 on both sides, causing them to blow dust. Each rotation of the nozzle 450 by 115° constitutes one working cycle. After one cycle, the dust sensor 600 checks whether the dust has been completely removed. If not, a second working cycle is initiated by returning the nozzles 450 to their initial positions, and so on. If the dust sensor 600 detects that a second cycle is not needed, the nozzles 450 rotate back into the mounting box 100, the lifting mechanism 200 retracts, the mounting box cover 120 rotates to cover the mounting box body 110, and the dust-blowing device returns to its original state.
[0048] During the blowing process, the first rotating motor 410 and the second rotating motor 430 work together to keep the nozzle 450 facing the windshield at an angle of 30-45°, which makes it easier to clean the glass surface more closely. Through the cooperation of the first rotating motor 410 and the second rotating motor 430, the nozzle 450 can achieve dynamic movement relative to the windshield, and perform dynamic cleaning of the windshield, resulting in a cleaner finish.
[0049] Optionally, the connecting tube 520 may be made of, but is not limited to, a flexible tube. Using a flexible tube facilitates the storage of the connecting tube 520 within the mounting housing 100.
[0050] Preferably, the lifting mechanism 200 is a three-stage lifting structure. The three-stage lifting structure can reduce the size of the lifting mechanism 200, so that the height of the mounting box 100 of the soot blowing device is not too high and occupies too much space.
[0051] In this invention, all actions of the soot blowing device are set and controlled by a controller.
