Description

Technical Field

[0001] This utility model relates to the field of purification device technology, specifically to a workshop air purification device. Background Technology

[0002] Workshop air purification devices draw in polluted air from the workshop through the air inlet. The polluted air is then purified by the filter plates and activated carbon filter inside the device before being discharged through the air outlet, thereby improving the air quality in the workshop.

[0003] In actual use, polluted air first passes through the filter plate to filter out dust and fine particles, which makes the filter plate easily covered with dust and fine particles. This reduces its filtration efficiency and may even cause blockage, seriously affecting the purification effect. Therefore, the filter plate needs to be removed and cleaned after a period of use, which is a rather cumbersome process and needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a workshop air purification device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A workshop air purification device includes a housing with a chamber inside. A filter plate is installed inside the chamber. An activated carbon filter element is mounted opposite each other inside the chamber via an mounting assembly. The activated carbon filter element is used to adsorb odors in the air entering the chamber. A striking assembly is provided inside the chamber to strike one side of the filter plate. A spray assembly is also provided inside the chamber to spray water onto the other side of the filter plate. A collection box is provided on the bottom wall of the chamber to collect water sprayed by the spray assembly and dust knocked off by the striking assembly. A drain pipe connected to the collection box is provided on the housing to discharge water and dust from the collection box.

[0007] Furthermore, the striking assembly includes a rotating rod disposed on the side wall of the chamber and rotatable, a rotating disk at one end of the rotating rod, and a mounting post at the edge of one side wall of the rotating disk; the striking assembly also includes a striking block, a driving post at the side wall of the striking block, a hinge seat at one end of the driving post, the hinge seat being connected to one end of the mounting post, and a limiting member at the side wall of the chamber for limiting the driving post.

[0008] Furthermore, the hinge seat includes a U-shaped mounting block, one end of the drive column extends into the mounting block, the mounting block is provided with a hinge rod that passes through the end of the drive column, and a connecting plate is provided on the side wall of the mounting block, the connecting plate being rotatably connected to one end of the mounting column by a bearing.

[0009] Furthermore, the limiting component includes a mounting rod arranged along the height direction of the chamber, and a limiting cylinder is provided at the lower end of the mounting rod perpendicular to the mounting rod, with the driving column passing through the limiting cylinder.

[0010] Furthermore, the spray assembly includes multiple water supply pipes disposed on the side wall of the chamber, and multiple water spray pipes facing the other side of the filter plate are disposed on the outer side wall of the water supply pipes along their length direction; a water tank connected to the water supply pipes is disposed on the side wall of the housing.

[0011] Furthermore, the installation assembly includes an installation frame, an activated carbon filter element installed within the installation frame, an elongated groove on the opposite side wall of the chamber, an elongated block that can slide into the elongated groove on the opposite side wall of the installation frame, a fixing block on the elongated block, a slot on the side wall of the housing that connects to the elongated groove and allows the fixing block to slide in, an installation groove inside the fixing block, a fixing plate on the side wall of the housing, and a locking element inside the installation groove for locking the fixing plate.

[0012] Furthermore, the locking component includes a locking rod that is slidably installed in the mounting groove. A locking plate is provided at one end of the locking rod. A notch is provided on the fixing plate for the locking plate to pass through. The locking rod is rotated to cause the locking plate to be misaligned with the notch. An abutment plate is sleeved on the locking rod located in the mounting groove. A spring is also provided on the locking rod located in the mounting groove. The spring is used to push the abutment plate to drive the locking plate to press against the side wall of the fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of the tapping component, enables the tapping component to tap one side of the filter plate, causing the filter plate to vibrate. This vibration causes the dust and fine particles on the filter plate to fall off, thereby preventing dust and fine particles from clogging the filter holes, reducing the filtration efficiency of the filter plate, and affecting the purification effect.

[0015] This invention, through the setting of the spray assembly, enables the spray assembly to spray water on the other side of the filter plate, thereby effectively removing dust and fine particles from the filter plate, thus enabling the filter plate to be cleaned better and eliminating the need for frequent cleaning of the filter plate over a period of time.

[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0033] The following is in conjunction with the appendix Figures 1-8 This embodiment will be described in further detail.

[0034] Combination Figures 1-8 As shown, an air purification device for a workshop in this embodiment includes a housing 101, a chamber 204 inside the housing 101, a filter plate 205 inside the chamber 204, an activated carbon filter element 304 mounted opposite each other in the chamber 204 via an installation assembly, the activated carbon filter element 304 being used to adsorb odors in the air entering the chamber 204, a striking assembly inside the chamber 204 for striking one side of the filter plate 205, a spray assembly inside the chamber 204 for spraying the other side of the filter plate 205, a collection box 203 on the bottom wall of the chamber 204 for collecting water sprayed by the spray assembly and dust knocked off by the striking assembly, and a drain pipe 202 on the housing 101 connected to the collection box 203 for discharging water and dust from the collection box 203.

[0035] In actual use, the housing 101 has an air inlet pipe 100 at one end and an air outlet pipe 103 at the other end. A fan 305 is installed in the chamber 204 located on one side of the activated carbon filter element 304, and filter holes are provided on the filter plate 205. The fan 305 draws air from the workshop into the chamber 204 through the air inlet pipe 100. The filter holes of the filter plate 205 filter dust and fine particles in the air entering the chamber 204. The activated carbon filter element 304 allows the air filtered by the filter plate 205 to be filtered again, thereby effectively removing odors from the air and purifying the air in the workshop. The purified air is then blown into the workshop through the air outlet pipe 103 by the fan 305.

[0036] In actual use, when the filter plate 205 is covered with dust and fine particles, the fan 305 is turned off to stop the air purification device from working. The tapping component is designed to tap one side of the filter plate 205, causing the filter plate 205 to vibrate. This vibration causes the dust and fine particles on the filter plate 205 to fall off, thus preventing dust and fine particles from clogging the filter holes, reducing the filtration efficiency of the filter plate 205, and affecting the purification effect.

[0037] When the tapping component stops tapping, the spraying component starts working. The spraying component is designed to spray water onto the other side of the filter plate 205, effectively removing dust and fine particles from the filter plate 205. Specifically, since dust and fine particles adhere to one side of the filter plate 205, spraying water onto the other side of the filter plate 205 allows the water to pass through the filter holes and effectively wash the dust and fine particles off the filter plate 205, thus ensuring the filter plate 205 is thoroughly cleaned and does not require frequent cleaning over a period of time.

[0038] The spray assembly continuously sprays water with a relatively low spray force, which effectively prevents water sprayed onto the filter plate 205 from splashing onto other parts of the chamber 204.

[0039] The filter plate 205 is fixedly installed in the chamber 204 by bolts, allowing the operator to remove the filter plate 205 for fine cleaning.

[0040] The collection box 203 is located below the filter plate 205 and has an opening at the top, so that dust and fine particles falling from the filter plate 205 can fall into the collection box 203 and be collected. At the same time, the collection box 203 can collect water dripping from the filter plate 205. Through the drain pipe 202, the water, dust and fine particles entering the collection box 203 can be discharged out of the chamber 204.

[0041] The drain pipe 202 is connected to the collection box 203. The bottom wall of the collection box 203 is provided with an inclined block 300 and a water guiding inclined surface. By setting the water guiding inclined surface, the water guiding inclined surface can better guide the water in the collection box 203 to the opening of the drain pipe 202, so as to better drain the water in the collection box 203.

[0042] The chamber 204 has an L-shaped abutment block 301 along its width. The lower side of the filter plate 205 abuts against the upper side of the abutment block 301, so that the filter plate 205 can better filter the air entering the chamber 204. The abutment block 301 is provided with a guide slope. The guide slope can guide the water dripping on the other side of the filter plate 205, so that the water dripping on the other side of the filter plate 205 can enter the collection box 203 through the filter hole at the lowest position on the filter plate 205.

[0043] Combination Figures 2-6As shown, in this embodiment, the striking assembly includes a rotating rod 206 that is rotatable and disposed on the side wall of the chamber 204. A rotating disk 207 is provided at one end of the rotating rod 206, and a mounting post 208 is provided on one side wall of the rotating disk 207 at the edge position. The striking assembly also includes a striking block 210, a driving post 211 is provided on the side wall of the striking block 210, a hinge seat is provided at one end of the driving post 211, and the hinge seat is connected to one end of the mounting post 208. A limiting member is provided on the side wall of the chamber 204, and the limiting member is used to limit the driving post 211.

[0044] In actual use, a motor 601 is provided on the side wall of the housing 101. The other end of the rotating rod 206 is connected to the output end of the motor 601. The rotating rod 206 is driven to rotate by the motor 601, so that the rotating rod 206 can drive the rotating disk 207 to drive the mounting column 208 to rotate. Since the hinge seat and the driving column 211 are hinged together, and the driving column 211 is limited by the limiting member, the mounting column 208 can drive the hinge seat to rotate. In turn, the rotation of the hinge seat can drive the driving column 211 to move horizontally back and forth, so that the driving column 211 can drive the striking block 210 to strike the filter plate 205.

[0045] In actual use, the hinged seat includes a U-shaped mounting block 500, one end of the drive column 211 extends into the mounting block 500, the mounting block 500 is provided with a hinge rod 402 that passes through the end of the drive column 211, and a connecting plate 501 is provided on the side wall of the mounting block 500. The connecting plate 501 is rotatably connected to one end of the mounting column 208 through a bearing, so that the drive column 211 can be hingedly mounted on the mounting block 500.

[0046] The limiting component includes a mounting rod 209 arranged along the height direction of the chamber 204. A limiting cylinder 212 is provided vertically at the lower end of the mounting rod 209. A drive column 211 is arranged through the limiting cylinder 212. Specifically, the drive column 211 and the limiting cylinder 212 are adapted to each other so that the outer wall of the drive column 211 can slide against the inner wall of the limiting cylinder 212, thereby preventing the drive column 211 from shaking inside the limiting cylinder 212. This allows the limiting cylinder 212 to better limit the drive column 211, so that the drive column 211 can move horizontally better.

[0047] The rotating rod 206 is mounted on the side wall of the chamber 204 via a bearing, thereby enabling the rotating rod 206 to be rotatably mounted within the chamber 204.

[0048] Combination Figures 3-6As shown, in this embodiment, the spray assembly includes a plurality of water supply pipes 302 disposed on the side wall of the chamber 204, and a plurality of water spray pipes 303 disposed along the length direction of the outer side wall of the water supply pipes 302 facing the other side of the filter plate 205; a water tank 600 connected to the water supply pipes 302 is disposed on the side wall of the housing 101.

[0049] In actual use, the water supply pipe 302, water tank 600 and spray pipe 303 in this embodiment enable water in the water tank 600 to enter the water supply pipe 302 and be sprayed onto the other side of the filter plate 205 through the spray pipe 303, thereby enabling the filter plate 205 to be cleaned better.

[0050] Combination Figures 6-8 As shown, in this embodiment, the installation assembly includes an installation frame 102, an activated carbon filter element 304 installed in the installation frame 102, a long groove 400 on the opposite side wall of the chamber 204, a long block 306 that can slide into the long groove 400 on the opposite side wall of the installation frame 102, a fixing block 200 on the long block 306, a slot 401 communicating with the long groove 400 and for the fixing block 200 to slide into on the side wall of the housing 101, an installation groove 706 in the fixing block 200, a fixing plate 201 on the side wall of the housing 101, and a locking member for locking the fixing plate 201 in the installation groove 706.

[0051] In actual use, the activated carbon filter element 304 is slidably installed on the mounting frame 102. Then, the elongated block 306 on the mounting frame 102 is aligned with the elongated groove 400 and inserted into the elongated groove 400, so that the activated carbon filter element 304 can slide into the chamber 204. Through the setting of the groove 401, the fixing block 200 and the fixing plate 201, the fixing block 200 can slide into the groove 401. When the fixing block 200 abuts against the corresponding side wall of the fixing plate 201, at this time, one end of the elongated block 306 abuts against the corresponding side wall of the elongated groove 400. Since the fixing plate 201 is fixedly installed on the housing 101, the locking member can fix the fixing block 200 on the fixing plate 201, so that the fixing block 200 can be fixedly installed on the housing 101, thereby allowing the activated carbon filter element 304 to be fixedly installed in the chamber 204.

[0052] The mounting frame 102 has an opening on one side, and the opposite side wall of the mounting frame 102 has a groove for the activated carbon filter element 304 to slide into. The groove allows the activated carbon filter element 304 to be installed in the mounting frame 102. Specifically, a rubber pad is provided in the groove. The rubber pad increases the friction between the activated carbon filter element 304 and the mounting frame 102, making it less likely for the activated carbon filter element 304 to slide out of the mounting frame 102.

[0053] In actual use, the long strip 306 and the long strip groove 400 are adapted to each other, so that the side wall of the long strip 306 can slide and fit against the corresponding side wall of the long strip groove 400, thereby preventing the long strip 306 from shaking in the long strip groove 400, and preventing the mounting frame 102 from shaking on the housing 101, thus allowing the activated carbon filter element 304 to be installed better.

[0054] Specifically, rubber pads are provided on both the elongated groove 400 and the elongated block 306. The rubber pads can better ensure the airtightness of the chamber 204.

[0055] In this embodiment, to facilitate the operation of the operator to pull out the mounting frame 102, a handle 104 is provided on the side wall of the mounting frame 102.

[0056] Combination Figures 7-8 As shown, in this embodiment, the locking member includes a locking rod 702 slidably installed in the mounting groove 706. A locking plate 701 is provided at one end of the locking rod 702. A notch 800 is provided on the fixing plate 201 for the locking plate 701 to pass through. The locking rod 702 is rotated to make the locking plate 701 misaligned with the notch 800. An abutment plate 705 is sleeved on the locking rod 702 located in the mounting groove 706. A spring 704 is also provided on the locking rod 702 located in the mounting groove 706. The spring 704 is used to push the abutment plate 705 to drive the locking plate 701 to press against the side wall of the fixing plate 201.

[0057] In actual use, the fixing block 200 slides along the slot 401. When the locking plate 701 abuts against the side wall of the fixing plate 201, the locking rod 702 is rotated, causing the locking plate 701 to rotate. When the locking plate 701 is aligned with the notch 800, the fixing block 200 continues to slide along the slot 401, so that the side wall of the fixing block 200 abuts against the side wall of the fixing plate 201, placing the locking plate 701 within the notch 800. Then, the locking rod 702 is pressed, causing the locking rod 702 to move and compress the abutment plate 705. Spring 704 drives locking plate 701 to extend out of notch 800. At this time, lock rod 702 is rotated so that locking rod 702 can drive locking plate 701 to rotate. When locking plate 701 is misaligned with notch 800, lock rod 702 is released. Under the action of spring 704, spring 704 can push abutment plate 705 to reset, so that abutment plate 705 can drive lock rod 702 to drive locking plate 701 to reset, so that locking plate 701 can abut against the other side wall of fixed plate 201, so that fixed block 200 can be fixed on fixed plate 201.

[0058] In actual use, the outer wall of the locking rod 702 is provided with an annular groove along its circumference, and the abutment plate 705 is provided with an annular block that extends into the annular groove. Through the setting of the annular groove and the annular block, the locking rod 702 can be rotated and installed on the abutment plate 705.

[0059] In this embodiment, to facilitate the operator to rotate and press the locking rod 702, a nut 703 is provided at one end of the locking rod 702. The nut 703 facilitates the operator to rotate and press the locking rod 702.

[0060] In practical use, this invention involves starting the fan 305, which draws air from the workshop into the chamber 204 through the air inlet pipe 100. The filter plate 205 filters dust and fine particles from the air entering the chamber 204. The activated carbon filter 304 further filters the air after it has passed through the filter plate 205, effectively removing odors and harmful substances, thus purifying the air in the workshop. The air is then further purified by the fan 305. The blower 5 allows the purified air to enter the workshop through the exhaust duct 103. When the filter plate 205 is covered with dust and fine particles, the fan 305 stops working. The striking component is set to strike one side of the filter plate 205, causing the dust and fine particles on the filter plate 205 to fall off due to vibration. Water is sprayed on the other side of the filter plate 205 through the spray component, which can better remove the dust and fine particles on the filter plate 205, thus enabling the filter plate 205 to be cleaned effectively.

[0061] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
