Description

Technical Field

[0001] This invention relates to the field of hydrocarbon removal and purification equipment, and in particular to a portable hydrocarbon removal and purification equipment. Background Technology

[0002] With the rapid development of industrialization and urbanization, air pollution has become increasingly serious, especially volatile organic compounds (VOCs) and hydrocarbons in indoor or localized areas, posing a significant threat to human health. To purify the air and improve living and working environments, various air purification devices are widely used in the market. Among them, hydrocarbon removal purification devices, as a specialized product, have high application value in laboratories, industrial workshops, and warehouses.

[0003] In existing technologies, most common air purification devices adopt a static structure, resulting in a large overall size. Internally, they typically include purification components such as a fan system, filter module, and activated carbon adsorption material. While they can achieve basic hydrocarbon removal, they generally suffer from the following technical problems: Bulky structure and inconvenient to carry: Traditional hydrocarbon removal and purification devices are large in size and have a fixed structure, which makes them unsuitable for mobile deployment in different spaces or environments, thus limiting their portable application capabilities. Inconvenient to clean and prone to clogging: As the core filtration component of the purification device, the filter easily accumulates a large amount of dust and particulate matter during use. If it is not cleaned or shaken off in time, it can easily become clogged, affecting airflow and filtration efficiency. Lack of effective self-cleaning structure for filters: Existing products mostly rely on manual disassembly of filters for cleaning or replacement, which is cumbersome and inefficient. Furthermore, inadequate cleaning over long-term use will further reduce the purification effect of the equipment. The purification system has a simple power structure and lacks functional coordination: some devices only use a single-stage fan drive mode and fail to integrate and optimize the internal transmission and purification structure, resulting in low operating efficiency and inability to effectively combine auxiliary mechanisms such as vibration cleaning, thus limiting its practicality. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing technologies, such as bulky structure, inconvenience in carrying, inconvenience in cleaning the filter, easy clogging, lack of effective self-cleaning structure for the filter, single power structure of the purification system, and lack of functional synergy.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a portable hydrocarbon removal and purification device, comprising: a purification device body; an air intake tube fixedly connected to the outer surface of the purification device body; a coarse cylinder fixedly connected to one end of the air intake tube; multiple hollow grooves formed on the outer surface of the coarse cylinder; multiple protrusions fixedly connected to the inner wall of the purification device body; springs II fixedly connected to the outer surfaces of each of the multiple protrusions; a movable ring fixedly connected to one end of each of the multiple springs II; multiple sliding grooves formed on the inner wall of the coarse cylinder; the movable ring slidably connected to the interior of the multiple sliding grooves; and a dustproof net detachably connected to the outer surface of the movable ring.

[0006] The technical effect of adopting the above-mentioned further solution is as follows: the coarse cylinder absorbs the gas into its interior, and the motor is mainly started by an external power source. The motor drives the air intake fan to rotate, and at this time the air intake fan absorbs the gas. A dustproof net is set on the surface of the coarse cylinder, which is mainly used to isolate dust in the gas and prevent dust from entering the interior of the purifier body through the long air intake tube.

[0007] In a preferred embodiment, a plurality of L-shaped blocks are fixedly connected to the outer surface of the coarse cylinder, and threaded rods are movably embedded inside the plurality of L-shaped blocks. One end of each of the plurality of threaded rods is rotatably connected to a round block via a bearing, and a round rod is movably embedded inside the plurality of L-shaped blocks.

[0008] The technical effect of adopting the above-mentioned further solution is that by rotating the threaded rod, the threaded rod moves inside the L-shaped block. At this time, under the limit of the round rod, the round block moves and separates from the outer surface of the dustproof net. At this time, the dustproof net can be removed from the inside of the movable ring for replacement or thorough cleaning, which is more convenient during disassembly.

[0009] In a preferred embodiment, multiple L-shaped blocks are fixedly connected to the outer surface of multiple circular blocks, the multiple circular blocks are located on the outer surface of the dustproof net, a motor is fixedly connected to the inner wall of the purifier body, and an air intake fan is fixedly connected to the output end of the motor.

[0010] The technical effect of adopting the above-mentioned further solution is that the rotation of the air intake fan can quickly draw the gas into the interior of the coarse cylinder, and then quickly enter the interior of the purifier body through the long intake tube.

[0011] In a preferred embodiment, the suction fan is located on one side of the dustproof net and rotates inside the coarse cylinder. The output end of the motor is fixedly connected to a second pulley. A belt is movably sleeved on the outer surface of the second pulley. A first pulley is movably sleeved on one end of the belt. The first pulley is rotatably connected to the inner wall of the coarse cylinder through a bearing.

[0012] The technical effect of adopting the above-mentioned further solution is that when the motor is started, it drives the second pulley to rotate. At this time, the second pulley drives the first pulley to rotate through the belt. The first pulley drives the small gear to rotate, and the small gear drives the large gear to rotate.

[0013] In a preferred embodiment, a small gear is fixedly connected to the outer surface of the pulley, a large gear is meshed with the outer surface of the small gear, a reciprocating screw is fixedly connected to the outer surface of the large gear, a moving block is movably sleeved on the outer surface of the reciprocating screw, and two limiting rods are fixedly connected to the inner wall of the coarse cylinder.

[0014] The technical effect of adopting the above-mentioned further solution is that the small gear drives the large gear to rotate. The circumference of the small gear is smaller than that of the large gear, so the rotational speed of the large gear is smaller than that of the small gear, and the rotational speed of the reciprocating screw is slower. At this time, the moving block slides on the outer surface of the reciprocating screw under the limit of the limit rod, so that the sliding speed of the moving block is slower.

[0015] In a preferred embodiment, both limiting rods are located on both sides of the outer surface of the reciprocating lead screw, the moving block is movably sleeved on the outer surface of the two limiting rods, and an impact block is fixedly connected to the outer surface of the moving block, the impact block being in contact with the outer surface of the dustproof net.

[0016] The technical effect of adopting the above-mentioned further solution is: while sliding, the impact block is moved and the impact block contacts the surface of the movable ring. At this time, under the limit of the second spring, the movable ring moves back and forth inside the slide groove, thereby causing the movable ring to vibrate, which in turn causes the dustproof net to vibrate. When the dustproof net isolates the dust, the dust adheres to its outer surface. After the dustproof net vibrates, the dust falls to the outside through the hollow groove.

[0017] In a preferred embodiment, a purification component is fixedly connected to the outer surface of the purifier body, a display is fixedly connected to the outer surface of the purifier body, an air outlet pipe is fixedly connected to the outer surface of the purifier body, and an activated carbon filter is provided inside the air outlet pipe.

[0018] The technical effect of adopting the above-mentioned further solution is that by picking up the entire device by hand, 103) can be used to view the data on the gas treatment inside the purifier body.

[0019] In a preferred embodiment, a fixing member is fixedly connected to the top of the outer surface of the purifier body, a handle is fixedly connected to the top of the outer surface of the purifier body, a fixing strip is fixedly connected to the outer surface of the fixing member, two springs are fixedly connected to the outer surface of the fixing strip, and a pull rod is movably embedded inside the fixing strip.

[0020] The technical effect of adopting the above-mentioned further solution is as follows: by pulling the lever, the limiting block is moved to one side. At this time, the coarse cylinder is taken out from the circular groove inside the fixing part. Two springs are set on one side of the surface of the limiting block. The two springs limit the limiting block, thereby fixing the coarse cylinder. When the coarse cylinder is not in use, it can be fixed, so that the long suction tube and the coarse cylinder will not drag on the ground when the purifier body is moved.

[0021] In a preferred embodiment, one end of the pull rod is fixedly connected to a limiting block, and the two springs are located on the outer surface of the limiting block. The thick cylinder is located inside the circular hole of the fixing member, and the limiting block is in contact with the outer surface of the thick cylinder.

[0022] The technical advantage of adopting the above-mentioned further solution is that it can be used to fix the thick cylinder and make it easy to handle.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this embodiment of the invention, the coarse cylinder absorbs the gas into its interior. The motor is started by an external power source, and the motor drives the suction fan to rotate. At this time, the suction fan absorbs the gas. A dustproof net is provided on the surface of the coarse cylinder, which is mainly used to isolate dust in the gas and prevent dust from entering the interior of the purifier body through the long suction tube.

[0024] 2. In this embodiment of the invention, by pulling the lever, the limiting block is moved to one side. At this time, the coarse cylinder is taken out from the circular groove inside the fixing part. Two springs are set on one side of the surface of the limiting block. The two springs limit the limiting block, thereby fixing the coarse cylinder. When the coarse cylinder is not in use, it can be fixed so that the long suction tube and the coarse cylinder will not drag on the ground when the purifier body is moved.

[0025] 3. In this embodiment of the invention, when the motor is started, it drives pulley two to rotate. At this time, pulley two drives pulley one to rotate via a belt. Pulley one drives a small gear to rotate, and the small gear drives a large gear to rotate. The circumference of the small gear is smaller than that of the large gear, so the speed of the large gear is less than that of the small gear, resulting in a slower speed of the reciprocating screw. At this time, the moving block slides on the outer surface of the reciprocating screw under the limit of the limit rod, so that the moving block slides slowly. While sliding, it drives the impact block to move. The impact block contacts the surface of the movable ring. At this time, under the limit of spring two, the movable ring reciprocates inside the slide groove, causing the movable ring to vibrate, which in turn causes the dustproof net to vibrate. When the dustproof net isolates dust, the dust adheres to its outer surface. After the dustproof net vibrates, the dust falls to the outside through the hollow groove, so that the dustproof net will not be blocked due to excessive dust during use.

[0026] 4. In this embodiment of the invention, by rotating the threaded rod, the threaded rod moves inside the L-shaped block. At this time, under the limitation of the round rod, the round block moves and detaches from the outer surface of the dustproof net. At this time, the dustproof net can be removed from the inside of the movable ring for replacement or thorough cleaning. Disassembly is relatively convenient. After use, under the limitation of the spring, the limiting block fixes the surface of the coarse cylinder, thereby fixing the coarse cylinder inside the fixing part. By lifting the entire purifier body with the handle, the purifier body performs hydrocarbon removal and purification treatment on the air. However, the gas enters the outdoors through the exhaust pipe. The activated carbon filter can filter the gas and reduce the chemical elements inside the gas. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-8 This embodiment provides a technical solution: a portable hydrocarbon removal purifier, comprising: a purifier body 101, an air intake tube 114 fixedly connected to the outer surface of the purifier body 101, a coarse cylinder 115 fixedly connected to one end of the air intake tube 114, a plurality of hollow grooves 133 formed on the outer surface of the coarse cylinder 115, a plurality of protrusions 125 fixedly connected to the inner wall of the purifier body 101, a second spring 126 fixedly connected to the outer surface of each of the protrusions 125, a movable ring 128 fixedly connected to one end of each of the springs 126, a plurality of sliding grooves 127 formed on the inner wall of the coarse cylinder 115, the movable ring 128 slidably connected inside the sliding grooves 127, and a dustproof net 134 detachably connected to the outer surface of the movable ring 128. In use, the coarse cylinder 115 absorbs the gas into its interior. The motor 116 is started by an external power source, and the motor 116 drives the suction fan 117 to rotate. At this time, the suction fan 117 absorbs the gas. A dustproof net 134 is provided on the surface of the coarse cylinder 115, which is mainly used to isolate dust in the gas and prevent dust from entering the interior of the purifier body 101 through the long suction tube 114.

[0031] like Figure 1-8As shown, in one embodiment, a plurality of L-shaped blocks 129 are fixedly connected to the outer surface of the coarse cylinder 115. Threaded rods 130 are movably embedded inside each of the L-shaped blocks 129. One end of each threaded rod 130 is rotatably connected to a round block 132 via a bearing. A round rod 131 is movably embedded inside each of the L-shaped blocks 129. By rotating the threaded rod 130, the threaded rod 130 moves inside the L-shaped block 129. At this time, the round block 132 moves under the limitation of the round rod 131, and the round block 132 disengages from the outer surface of the dustproof net 134. At this time, the dustproof net 134 can be removed from the inside of the movable ring 128 for replacement or thorough cleaning, which is relatively convenient.

[0032] like Figure 1-8 As shown, in one embodiment, multiple L-shaped blocks 129 are fixedly connected to the outer surface of multiple circular blocks 132. The multiple circular blocks 132 are located on the outer surface of the dustproof net 134. A motor 116 is fixedly connected to the inner wall of the purifier body 101. An air intake fan 117 is fixedly connected to the output end of the motor 116. The rotation of the air intake fan 117 can quickly absorb the gas into the interior of the coarse cylinder 115, and then quickly enter the interior of the purifier body 101 through the long air intake tube 114.

[0033] like Figure 1-8 As shown, in one embodiment, the suction fan 117 is located on one side of the dustproof net 134. The suction fan 117 rotates inside the coarse cylinder 115. The output end of the motor 116 is fixedly connected to the pulley 2 136. The outer surface of the pulley 2 136 is movably fitted with a belt 118. One end of the belt 118 is movably fitted with a pulley 135. The pulley 135 is rotatably connected to the inner wall of the coarse cylinder 115 through a bearing. When the motor 116 is started, it drives the pulley 2 136 to rotate. At this time, the pulley 2 136 drives the pulley 135 to rotate through the belt 118. The pulley 135 drives the pinion 119 to rotate. The pinion 119 drives the gear 120 to rotate.

[0034] like Figure 1-8 As shown, in one embodiment, a small gear 119 is fixedly connected to the outer surface of the pulley 135, a large gear 120 is meshed with the outer surface of the small gear 119, a reciprocating screw 121 is fixedly connected to the outer surface of the large gear 120, and a moving block 123 is movably sleeved on the outer surface of the reciprocating screw 121. Two limiting rods 122 are fixedly connected to the inner wall of the coarse cylinder 115. The small gear 119 drives the large gear 120 to rotate. The circumference of the small gear 119 is smaller than the circumference of the large gear 120, so that the rotational speed of the large gear 120 is smaller than the rotational speed of the small gear 119, and the rotational speed of the reciprocating screw 121 is slower. At this time, the moving block 123 slides on the outer surface of the reciprocating screw 121 under the limitation of the limiting rods 122, so that the sliding speed of the moving block 123 is slower.

[0035] like Figure 1-8 As shown, in one embodiment, two limiting rods 122 are located on both sides of the outer surface of the reciprocating lead screw 121. The moving block 123 is movably sleeved on the outer surface of the two limiting rods 122. An impact block 124 is fixedly connected to the outer surface of the moving block 123. The impact block 124 contacts the outer surface of the dustproof net 134. While sliding, the impact block 124 moves and contacts the surface of the movable ring 128. At this time, under the limitation of the second spring 126, the movable ring 128 moves back and forth inside the slide groove 127, thereby causing the movable ring 128 to vibrate, which in turn causes the dustproof net 134 to vibrate. When the dustproof net 134 isolates the dust, the dust adheres to its outer surface. After the dustproof net 134 vibrates, the dust falls to the outside through the hollow groove 133.

[0036] like Figure 1-8 As shown, in one embodiment, a purification component 102 is fixedly connected to the outer surface of the purifier body 101, a display 103 is fixedly connected to the outer surface of the purifier body 101, an air outlet pipe 105 is fixedly connected to the outer surface of the purifier body 101, and an activated carbon filter 104 is provided inside the air outlet pipe 105. The entire device can be picked up by the handle 107, and the display 103 is used to view the data of gas treatment inside the purifier body 101.

[0037] like Figure 1-8 As shown, in one embodiment, a fixing member 108 is fixedly connected to the top of the outer surface of the purifier body 101, and a handle 107 is fixedly connected to the top of the outer surface of the purifier body 101. A fixing strip 111 is fixedly connected to the outer surface of the fixing member 108, and two springs 109 are fixedly connected to the outer surface of the fixing strip 111. A pull rod 112 is movably embedded inside the fixing strip 111. By pulling the pull rod 112, the limiting block 113 is moved to one side. At this time, the coarse cylinder 115 is taken out from the circular groove inside the fixing member 108. Two springs 109 are provided on one side of the surface of the limiting block 113. The two springs 109 limit the limiting block 113, thereby fixing the coarse cylinder 115 to the limiting block 113. When the coarse cylinder 115 is not in use, it can be fixed so that the long suction tube 114 and the coarse cylinder 115 will not drag on the ground when the purifier body 101 is moved.

[0038] like Figure 1-8 As shown, in one embodiment, one end of the pull rod 112 is fixedly connected to the limiting block 113, and two springs 109 are located on the outer surface of the limiting block 113. The coarse cylinder 115 is located inside the circular hole of the fixing member 108, and the limiting block 113 contacts the outer surface of the coarse cylinder 115 to fix the coarse cylinder 115 for easy removal.

[0039] Working principle: During use, pulling the lever 112 moves the limiting block 113 to one side, allowing the coarse cylinder 115 to be removed from the circular groove inside the fixing part 108. Two springs 109 are provided on one side of the surface of the limiting block 113, which limit the limiting block 113, thus fixing the coarse cylinder 115. When the coarse cylinder 115 is not in use, it can be fixed to prevent the suction tube 114 and the coarse cylinder 115 from dragging on the ground when the purifier body 101 is moved. The display 103 is used to view the data on gas processing inside the purifier body 101. The coarse cylinder 115 absorbs gas into its interior, mainly powered by an external power source to start the motor 116. Motor 116 drives the suction fan 117 to rotate, at which time the suction fan 117 absorbs the gas. A dustproof net 134 is set on the surface of the coarse cylinder 115, mainly used to isolate dust in the gas and prevent dust from entering the interior of the purifier body 101 through the long suction tube 114. When the motor 116 is started, it drives the pulley 136 to rotate. At this time, the pulley 136 drives the pulley 135 to rotate through the belt 118. The pulley 135 drives the pinion 119 to rotate. The pinion 119 drives the large gear 120 to rotate. The circumference of the pinion 119 is smaller than that of the large gear 120, so the speed of the large gear 120 is less than that of the pinion 119, making the speed of the reciprocating screw 121 slower. At this time, the moving block 123 is at the limit rod. Under the limit of 122, the reciprocating screw 121 slides on its outer surface, causing the moving block 123 to slide at a slower speed. Simultaneously, the moving block 124 moves, contacting the surface of the movable ring 128. At this time, under the limit of spring 126, the movable ring 128 reciprocates inside the slide groove 127, causing it to vibrate. This, in turn, causes the dustproof net 134 to vibrate. When the dustproof net 134 isolates dust, the dust adheres to its outer surface. After the dustproof net 134 vibrates, the dust falls out through the hollow groove 133, preventing the dustproof net 134 from becoming clogged due to excessive dust during use. By rotating the threaded rod 130, the threaded rod 130 moves within the L-shaped block 12. The internal movement of 9 causes the circular block 132 to move under the limit of the circular rod 131. The circular block 132 detaches from the outer surface of the dustproof net 134. At this time, the dustproof net 134 can be removed from the inside of the movable ring 128 for replacement or thorough cleaning. Disassembly is relatively convenient. After use, the limiting block 113 is fixed to the surface of the coarse cylinder 115 under the limit of the spring 109, so that the coarse cylinder 115 is fixed inside the fixing member 108. The entire purifier body 101 is lifted by the handle 107. The purifier body 101 performs hydrocarbon removal purification treatment on the air. However, the gas enters the outside through the exhaust pipe 105. However, the activated carbon filter 104 can filter the gas and reduce the chemical elements inside the gas.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
