Description

Technical Field

[0001] The present invention relates to the technical field of vehicle air purification, and in particular to an air purification device for a vehicle engineering inspection vehicle. Background Art

[0002] Vehicle engineering is an interdisciplinary major that integrates multiple disciplines such as mechanical engineering, electronic technology, and computer science. It focuses on the design, manufacturing, research and development, testing, and performance optimization of vehicles (including automobiles and rail transit vehicles). Inspection vehicles may operate in environments with poor air quality, such as construction sites and industrial areas. Effective air purification devices are needed to purify the air inside the vehicle to protect the health of people inside.

[0003] When the existing air purification device for vehicle engineering inspection vehicles purifies the air, since the air inside the inspection vehicle contains dust particles, the dust particles are often filtered through the dust filter during the purification process. The continuous accumulation of dust can easily cause the filter to be blocked, significantly reducing the purification efficiency. The traditional treatment method requires manual disassembly of the filter and the use of special tools to remove the accumulated dust one by one, which not only consumes a lot of time and manpower, but some purification devices equipped with automatic cleaning functions can achieve filter dust removal, but after each cleaning is completed, the dust needs to be manually poured out in time to avoid affecting the subsequent filtering operation, causing inconvenience in the use of the entire purification device.

[0004] For this purpose, we propose an air purification device for vehicle engineering inspection vehicles. Summary of the Invention

When the cleaning is completed, the sleeve 812 is reset, and the blocking component 9 is blocked. In the later stage, you only need to remove the collection shell 86 regularly to pour out impurities and dust.

[0039] Among them, the transmission assembly 84 includes a slide 844 that is slidably connected to the inner wall of the mounting frame 81, two electric push rods 843 are installed on the surface of the mounting frame 81, and the output end is fixedly connected to the surface of the slide 844, the inner wall of the slide 844 is rotatably connected to the transmission rod 841, and the inner walls of the upper and lower ends of the transmission rod 841 are slidably connected to the slide 845, and one end of the two slides 845 is fixedly connected to the upper joint 847 and the lower joint 848 respectively. The surfaces of fan 1 82 and fan 2 83 are provided with slots for the upper joint 847 and the lower joint 848 to be inserted, and buffer springs 846 are provided between the upper joint 847 and the lower joint 848 and the transmission rod 841, and the buffer spring 846 is sleeved on the slide 845. A motor 842 is installed on the surface of the slide 844, and the output end of the motor 842 is connected to the transmission rod 841 through a belt. The upper joint 847 and the lower joint 848 are composed of a ring and four cylindrical pins fixed on the ring.

[0040] In the embodiment: when it is necessary to control the rotation of fan 1 82, the electric push rod 1 843 drives the slide 844 to move upward, so that the upper joint 847 contacts the surface of fan 1 82, and the buffer spring 846 is stressed. When the motor 842 rotates through the belt, the transmission rod 841 drives the upper joint 847 to rotate. When the upper joint 847 is aligned with the slot on the surface of fan 1 82, the buffer spring 846 drives the upper joint 847 to insert into the slot. Then the transmission rod 841 cooperates with the upper joint 847 to drive the fan 1 82 to rotate, and cooperates with the air inlet 3 to inhale the air in the car for filtering and purification. When it is necessary to control When the fan 2 83 rotates, the electric push rod 1 843 drives the slide 844 to move downward, allowing the lower joint 848 to contact the surface of the fan 2 83, and at the same time the buffer spring 846 is subjected to force. When the motor 842 rotates through the belt, the transmission rod 841 drives the lower joint 848 to rotate. After the lower joint 848 is aligned with the slot on the surface of the fan 2 83, the buffer spring 846 drives the lower joint 848 to be inserted into the slot, and then the transmission rod 841 cooperates with the upper joint 847 to drive the fan 1 82 to rotate, blowing air toward the side close to the collection shell 86, and blowing the dust on the dust filter 5 into the collection shell 86 for collection.

[0041] Among them, the sealing assembly 9 includes an annular frame 91 installed on the inner wall of the shell 1, and a plurality of ash inlet holes 95 are opened on the surface of the annular frame 91. A plurality of fixed rods 93 are fixedly connected to the lower surface of the annular frame 91. The surface of the fixed rod 93 is rotatably connected to the baffle 92. The surface of the fixed rod 93 is sleeved with a torsion spring 94. The two ends of the torsion spring 94 are fixedly connected to the surfaces of the fixed rod 93 and the baffle 92 respectively. The upper surface of the annular frame 91 is chamfered.

[0042] In the embodiment: when sealing, the torsion spring 94 always drives the baffle 92 to fit with the lower surface of the annular frame 91, blocks the ash inlet 95, and achieves sealing. During the cleaning process, the sleeve 812 can block the air inlet 3. When the sleeve 812 moves, it can drive the extrusion part to squeeze the baffle 92 and control the baffle 92 to rotate and open. After the chamfer is set, the dust can better enter the collection shell 86.

[0043] Among them, a limiting component 85 is set on the surface of the mounting frame 81, and the limiting component 85 includes an upper limit part and a lower limit part. The upper limit part limits the rotation of fan 1 82, and the lower limit part limits the rotation of fan 2 83. The upper limit part and the lower limit part both include a movable frame 851 that is slidably connected to the inner wall of the mounting frame 81. A return spring 852 is sleeved on the surface of the movable frame 851, and the two ends of the return spring 852 are fixedly connected to the surfaces of the movable frame 851 and the mounting frame 81 respectively. A limiting plate 854 is fixedly connected to the surface of the movable frame 851, and two auxiliary rods 853 are fixedly connected to the surface of the movable frame 851.

[0044] In the embodiment: when the limiting plates 854 in the upper limit portion and the lower limit portion contact fan 1 82 and fan 2 83 respectively, the rotation of fan 1 82 and fan 2 83 can be restricted. When the upper joint 847 in the transmission assembly 84 contacts fan 1 82, the mounting frame 81 can push the auxiliary rod 853 in the upper limit portion, driving the movable frame 851 and the limiting plate 854 to move, and the limiting plate 854 loses contact with fan 1 82. Conversely, after the lower joint 848 contacts fan 2 83, the limiting plate 854 in the lower limit portion can lose contact with fan 2 83, and the limiting plate 854 in the upper limit portion restricts fan 1 82.

[0045] Among them, the positioning part includes a pin 810 that is slidably connected to the inner wall of the cleaning brush 89, the pin 810 is plugged into the inner wall of the extension shaft 88, and the surface of the pin 810 is sleeved with a positioning spring 811. The two ends of the positioning spring 811 are respectively fixedly connected to the surface of the pin 810 and the cleaning brush 89. The cleaning brush 89 can be restricted on the extension shaft 88 by cooperating with the positioning spring 811 through the pin 810, so as to facilitate removal and replacement.

[0046] The working principle of the present invention is as follows: when in use, the entire device can be placed in the interior of the inspection vehicle. Then, when purifying the air, first turn on the electric push rod 843 to drive the slide 844 to move upward, so that the upper joint 847 contacts the surface of the fan 82, and at the same time, the buffer spring 846 is stressed. When the motor 842 rotates through the belt, the transmission rod 841 drives the upper joint 847 to rotate. When the cylindrical pin in the upper joint 847 is aligned with the slot on the surface of the fan 82, the buffer spring 846 drives the cylindrical pin in the upper joint 847 to insert into the slot. Then the transmission rod 841 cooperates with the upper joint 847 to drive the fan 82 to rotate. The fan 82 sucks air, and the air in the car is sucked into the shell 1 through the air inlet 3. Then, it is filtered and purified through the dust filter 5, the activated carbon filter 6 and the ultraviolet lamp group 7 in sequence, and then discharged through the air outlet 2, which significantly improves the air quality in the car and provides a healthy and comfortable working environment for the people in the car.

[0047] When cleaning is needed, first open the electric push rod 2 813 to drive the sleeve 812 to move. When the sleeve 812 moves, it loses the obstruction to the filter air inlet, and can drive the push rod 814 to move. The push rod 814 squeezes the baffle 92, controls the baffle 92 to rotate and open, and the torsion spring 94 is stressed. When the sleeve 812 completely blocks the air inlet 3, the electric push rod 1 843 then drives the slide 844 to move downward, allowing the lower joint 848 to contact the surface of the fan 2 83. At the same time, the buffer spring 846 is stressed. When the motor 842 rotates through the belt, the transmission rod 841 drives the lower joint 848 to rotate. After the cylindrical pin in the lower joint 848 is aligned with the slot on the surface of the fan 2 83, the buffer spring 846 drives the lower joint 848 to rotate. The cylindrical pin is inserted into the slot, and then the transmission rod 841 cooperates with the upper joint 847 to drive the fan 82 to rotate, so that air can enter through the filtered air inlet hole. At the same time, the extension shaft 88 drives the cleaning brush 89 to rotate, cleaning the dust filter 5 while blowing the cleaned garbage into the collection shell 86. After the chamfered angle of the upper surface of the annular frame 91 is set, the dust can better enter the collection shell 86, and the gas is discharged through the filtered air outlet hole and the dust is filtered in the collection shell 86. When the cleaning is completed, the sleeve 812 is reset, and the torsion spring 94 drives the baffle 92 to reset and fit with the lower surface of the annular frame 91, covering the ash inlet 95 to achieve blocking. In the later stage, it is only necessary to remove the collection shell 86 regularly to pour out impurities and dust.

[0048] When the upper joint 847 in the transmission assembly 84 contacts with fan 1 82 to control the rotation of fan 1 82, the mounting frame 81 can push the auxiliary rod 853 in the upper limit portion, driving the movable frame 851 and the limiting plate 854 to move, and the limiting plate 854 loses contact with fan 1 82 and can operate normally. At this time, the return spring 852 in the lower limit portion exerts pressure on the movable frame 851 and the limiting plate 854, and the limiting plate 854 fits on fan 2 83 to limit the rotation of fan 2 83. Conversely, after the lower joint 848 contacts with fan 2 83, the limiting plate 854 of the lower limit portion can lose contact with fan 2 83, and the limiting plate 854 in the upper limit portion limits fan 1 82.

[0049] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device that performs control such as a computer.
