Description

Technical Field

[0001] The utility model relates to an indoor circulation fan with a self-cleaning effect, belonging to the technical field of fans. Background Art

[0002] A fan is a machine that relies on the input mechanical energy to increase the gas pressure and pump the gas. It is a driven fluid machine. The fan is the Chinese customary abbreviation for gas compression and gas transportation machinery. Generally, the fan includes a ventilator, a blower, and a wind turbine. Fans are widely used in ventilation, dust removal, and cooling of factories, mines, tunnels, cooling towers, vehicles, ships, and buildings; ventilation and air extraction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household electrical appliances; drying and selection of grains, air source of wind tunnels, and inflation and propulsion of hovercrafts, etc.

[0003] Chinese Patent Publication (CN217558651U) discloses a cross-flow through-flow fan with a self-cleaning effect, including a housing. A filter cover is slidably connected to the outside of the housing. A support shaft is rotatably connected inside the filter cover. A cross bar is welded on the support shaft. Brush hairs are arranged on the cross bar. A sealing sleeve is rotatably connected to the outside of the support shaft. The sealing sleeve is bonded to the filter cover. A connecting rod is welded inside the housing. A support disk is welded on the connecting rod. A motor is fixedly installed on the support disk. The rotating shaft of the motor is rotatably connected to the support disk. By setting structures such as a support shaft, a cross bar, brush hairs, a sealing sleeve, a connecting rod, a support disk, a motor, a rotating shaft, and a sleeve, the motor drives the sleeve to rotate, and then the support shaft drives the cross bar to rotate, so that the brush hairs brush the filter cover, making the dust attached to the filter cover fall off, enabling the device to self-clean and avoiding manual cleaning.

[0004] In the above device, since the motor is fixedly installed inside the housing and the connection method with the cross bar is to penetrate the middle end of the filter screen, the filtering area of the filter screen becomes smaller. At the same time, the size of the cross bar is smaller than that of the filter screen. When cleaning the filter screen, the dust on the surface of the filter screen cannot be completely cleaned. Moreover, the installation method of the filter screen is mainly fixed by a limit pin. After long-term use, since the limit pin itself does not have the force to move inward, the vibration generated by the motor during operation may cause the limit pin to fall off the surface of the housing, thereby affecting the installation work of the filter screen.

[0005] Therefore, an indoor circulation fan with a self-cleaning effect is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides an indoor circulation fan with a self-cleaning effect to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical solution of the utility model is realized as follows: An indoor circulation fan with a self-cleaning effect, including a fan body, a filter screen is arranged in the inner cavity of the fan body, and insertion holes are opened on both the upper and lower sides of the filter screen;

[0008] Disassembly mechanisms are arranged on both the upper and lower sides of the fan body. The disassembly mechanism includes box boxes, and the box boxes are fixedly installed on both the upper and lower sides of the fan body. Slide bars are fixedly installed in the inner cavities of the two box boxes. Sliders are slidably connected to the left and right sides of the surfaces of the two slide bars. Connecting rods are movably connected to the inner sides of the four sliders. Hardened springs are fixedly installed on the inner sides of the four sliders. Clamping plates are movably connected to the inner sides of the four connecting rods. Moving plates are fixedly installed on the inner sides of the four clamping plates. Insert blocks are fixedly installed on the inner sides of the two moving plates. Pull rods are fixedly installed on the outer sides of the two moving plates. Pulling plates are fixedly installed on the outer sides of the eight pull rods;

[0009] A cleaning mechanism is arranged on the front side of the fan body. The cleaning mechanism includes a mounting frame. The mounting frame is arranged on the front side of the fan body. A motor is fixedly installed on the front side of the mounting frame. A connecting shaft is fixedly connected to the output end of the motor. A fixing plate is fixedly installed on the rear side of the connecting shaft. A clamping block is fixedly installed on the rear side of the fixing plate. A cleaning plate is arranged on the rear side of the clamping block.

[0010] Further preferably, movable grooves are opened on the outer sides of the two box boxes, and the eight pull rods all penetrate through the inner cavities of the eight movable grooves and extend to the outer sides of the two box boxes.

[0011] Further preferably, sliding grooves are opened on the rear sides of the inner cavities of the two box boxes, and the rear sides of the four sliders are all slidably connected to the inner cavities of the two sliding grooves.

[0012] Further preferably, chute grooves are opened on the left and right sides of the inner cavities of the two box boxes, and the outer sides of the two moving plates are all slidably connected to the inner cavities of the four chute grooves.

[0013] Further preferably, slot holes are opened on both the upper and lower sides of the fan body, and the two insert blocks all penetrate through the inner cavities of the two slot holes and extend into the inner cavity of the insertion hole.

[0014] Further preferably, mounting bolts are threadedly connected to the four circumferences of the front side of the mounting frame, and the rear sides of the four mounting bolts are all threadedly connected to the inner surface of the fan body.

[0015] Further preferably, a plurality of brush hairs are fixedly installed on the rear side of the cleaning plate, and the rear sides of the brush hairs are attached to the front side of the filter screen.

[0016] Further preferably, a clamping groove is formed in the front side of the cleaning plate, and the clamping block is clamped in the inner cavity of the clamping groove.

[0017] Since the embodiment of the present utility model adopts the above technical solutions, it has the following advantages:

[0018] First, by setting a disassembly mechanism in the present utility model, when the pull plate is pulled and moved outward, the pull rod drives the moving plate to move outward synchronously. At this time, the moving plate drives the clamping plate and the insertion block to move outward synchronously. As the clamping plate moves, the connecting rod flips inward, and the slider moves inward. At this time, the hard spring deforms due to the extrusion of the slider. Then, the filter screen is placed into the inner cavity of the fan body, and the pull plate is released. At this time, due to the disappearance of the pulling force, the hard spring deforms again, and it pushes the slider to move outward through its own tension. As the slider moves, the clamping plate flips outward, and it pushes the clamping plate, the moving plate, and the insertion block to move inward. The insertion block is inserted into the inner cavity of the jack, completing the fixing work of the filter screen. Since the hard spring itself has a certain degree of tension, it can apply a continuous inward moving force to the insertion block. Compared with using methods such as inserting pins for fixing, it can effectively prevent the insertion pin from loosening from the surface of the fan body due to the vibration of the motor, thereby affecting the fixing work of the filter screen, and improving the stability during the installation of the filter screen. By setting a cleaning mechanism, through the output of the motor, the connecting shaft rotates, and the fixing plate drives the clamping block to rotate. At this time, the cleaning plate and the brush rotate synchronously driven by the clamping block. At this time, the brush cleans the dust adhered to the surface of the filter screen, effectively preventing the filter screen from being covered with a large amount of dust on its surface after being used for a long time, resulting in a deterioration of the filtering effect of the filter screen and then affecting the normal ventilation work.

[0019] Second, by setting an activity groove in the present utility model, the moving direction of the pull rod can be limited, avoiding the deviation of the pull rod during movement and then affecting the fixing work of the filter screen. By setting a sliding groove, the movement of the slider can be limited, effectively preventing the problem that the filter screen cannot be fixed due to the change in the moving direction of the slider. By setting a sliding groove, the moving direction of the moving plate can be limited, improving the stability of the moving plate during movement and avoiding the deterioration of the fixing effect on the filter screen. By setting a slot, the moving direction of the insertion block can be limited, enabling the insertion block to be stably inserted into the inner cavity of the jack, thereby realizing the fixing work of the filter screen. By setting installation bolts, it is convenient to disassemble the whole cleaning mechanism, facilitating the repair and replacement of the components in the cleaning mechanism. By setting the brush, its material is relatively soft, which can avoid damaging the filter screen when cleaning the filter screen. By setting a clamping groove, it is convenient to disassemble and replace the cleaning plate, avoiding the shedding of the soft hairs on the surface of the brush after long-term use, thereby affecting the cleaning effect on the filter screen.

[0020] The above summary is only for the purpose of the specification and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present utility model will be readily apparent by reference to the accompanying drawings and the following detailed description.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0029] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] As Figures 1-5 shown, an embodiment of the utility model provides an indoor circulation fan with a self-cleaning effect, which includes a fan body 1. A filter screen 4 is arranged in the inner cavity of the fan body 1, and insertion holes 5 are formed on both the upper and lower sides of the filter screen 4;

[0032] Disassembly mechanisms 2 are arranged on both the upper and lower sides of the fan body 1. The disassembly mechanism 2 includes a box 201, and the boxes 201 are fixedly installed on both the upper and lower sides of the fan body 1. Slide rods 202 are fixedly installed in the inner cavities of the two boxes 201. Slide blocks 203 are slidably connected to the left and right sides of the surfaces of the two slide rods 202. Connecting rods 205 are movably connected to the inner sides of the four slide blocks 203. Hardened springs 204 are fixedly installed on the inner sides of the four slide blocks 203. Clamping plates 206 are movably connected to the inner sides of the four connecting rods 205. Moving plates 207 are fixedly installed on the inner sides of the four clamping plates 206. Insert blocks 208 are fixedly installed on the inner sides of the two moving plates 207. Pull rods 209 are fixedly installed on the outer sides of the two moving plates 207. Pulling plates 210 are fixedly installed on the outer sides of the eight pull rods 209;

[0033] A cleaning mechanism 3 is arranged on the front side of the fan body 1. The cleaning mechanism 3 includes a mounting frame 301, and the mounting frame 301 is arranged on the front side of the fan body 1. A motor 302 is fixedly installed on the front side of the mounting frame 301. The output end of the motor 302 is fixedly connected to a connecting shaft 303. A fixing plate 304 is fixedly installed on the rear side of the connecting shaft 303. A clamping block 305 is fixedly installed on the rear side of the fixing plate 304. A cleaning plate 306 is arranged on the rear side of the clamping block 305.

[0034] By setting the disassembly mechanism 2, pulling the pull plate 210 to move outward, at this time the pull rod 209 drives the moving plate 207 to move outward synchronously. At this time, the moving plate 207 drives the clamping plate 206 and the insertion block 208 to move outward synchronously. As the clamping plate 206 moves, the connecting rod 205 flips inward and makes the slider 203 move inward. At this time, the hard spring 204 deforms due to the extrusion of the slider 203. Then, the filter screen 4 is placed into the inner cavity of the fan body 1, and the pull plate 210 is released. At this time, due to the disappearance of the pulling force, the hard spring 204 deforms again and pushes the slider 203 to move outward through its own tension. As the slider 203 moves, the clamping plate 206 flips outward and pushes the clamping plate 206, the moving plate 207 and the insertion block 208 to move inward. The insertion block 208 is inserted into the inner cavity of the jack 5 to complete the fixing work of the filter screen 4. Since the hard spring 204 itself has a certain degree of tension, it can apply a continuous inward moving force to the insertion block 208. Compared with using methods such as pins for fixing, it can effectively prevent the pins from loosening from the surface of the fan body 1 due to the vibration of the motor 302, thereby affecting the fixing work of the filter screen 4 and improving the stability during the installation of the filter screen 4. By setting the cleaning mechanism 3, through the output of the motor 302, the connecting shaft 303 rotates, and the fixing plate 304 drives the clamping block 305 to rotate. At this time, the cleaning plate 306 and the brush 307 rotate synchronously driven by the clamping block 305. At this time, the brush 307 cleans the dust adhered to the surface of the filter screen 4, effectively preventing the filter screen 4 from being covered with a large amount of dust on its surface after being used for too long, resulting in a poor filtering effect of the filter screen 4 and then affecting the normal ventilation work.

[0035] Embodiment 2

[0036] In one embodiment, movable grooves 211 are opened on the outer sides of both box bodies 201. All eight pull rods 209 penetrate through the inner cavities of the eight movable grooves 211 and extend to the outer sides of the two box bodies 201. Sliding grooves 212 are opened at the rear sides of the inner cavities of the two box bodies 201. The rear sides of the four sliders 203 are slidably connected to the inner cavities of the two sliding grooves 212. Chute grooves 213 are opened on the left and right sides of the inner cavities of the two box bodies 201. The outer sides of the two moving plates 207 are slidably connected to the inner cavities of the four chute grooves 213. Slot holes 214 are opened on the upper and lower sides of the fan body 1. Both insertion blocks 208 penetrate through the inner cavities of the two slot holes 214 and extend to the inner cavity of the jack 5. Installation bolts 308 are threadedly connected to the four circumferences on the front side of the mounting frame 301. The rear sides of the four installation bolts 308 are threadedly connected to the inner surface of the fan body 1. A plurality of brushes 307 are fixedly installed on the rear sides of the cleaning plates 306. The rear sides of the brushes 307 are attached to the front side of the filter screen 4. A clamping groove 309 is opened on the front side of the cleaning plate 306. The clamping block 305 is clamped in the inner cavity of the clamping groove 309.

[0037] By setting the active slot 211, the moving direction of the pull rod 209 can be limited, preventing the pull rod 209 from shifting during movement, which may otherwise affect the fixing of the filter screen 4. By setting the sliding slot 212, the movement of the slider 203 can be limited, effectively avoiding the problem that the filter screen 4 cannot be fixed due to a change in the moving direction of the slider 203. By setting the sliding groove 213, the moving direction of the moving plate 207 can be limited, improving the stability of the moving plate 207 during movement and preventing the fixing effect of the filter screen 4 from deteriorating. By setting the insertion slot 214, the moving direction of the insertion block 208 can be limited, enabling the insertion block 208 to stably insert into the inner cavity of the insertion hole 5, thus realizing the fixing of the filter screen 4. By setting the mounting bolt 308, the overall cleaning mechanism 3 can be easily disassembled, facilitating the repair and replacement of components in the cleaning mechanism 3. By setting the brush 307, which has a soft material, it can avoid damaging the filter screen 4 during cleaning. By setting the clamping groove 309, the cleaning plate 306 can be easily disassembled and replaced, preventing the soft hairs on the surface of the brush 307 from falling off after long-term use, which may otherwise affect the cleaning effect of the filter screen 4.

[0038] When the present utility model is in operation: When the filter screen 4 needs to be installed, by pulling the pull plate 210 outward, the pull rod 209 drives the moving plate 207 to move outward synchronously. At this time, the moving plate 207 drives the clamping plate 206 and the insertion block 208 to move outward synchronously. As the clamping plate 206 moves, the connecting rod 205 flips inward, causing the slider 203 to move inward. At this time, the rigid spring 204 deforms due to the extrusion of the slider 203. Subsequently, the filter screen 4 is placed into the inner cavity of the fan body 1, and the pull plate 210 is released. At this time, due to the disappearance of the pulling force, the rigid spring 204 deforms again and uses its own tension to push the slider 203 to move outward. As the slider 203 moves, the clamping plate 206 flips outward and pushes the clamping plate 206, the moving plate 207, and the insertion block 208 to move inward. The insertion block 208 inserts into the inner cavity of the insertion hole 5, completing the fixing of the filter screen 4. After the filter screen 4 has been used for a long time and is covered with a lot of dust, subsequently, through the output of the motor 302, the connecting shaft 303 rotates, causing the fixing plate 304 to drive the clamping block 305 to rotate. At this time, the cleaning plate 306 and the brush 307 rotate synchronously driven by the clamping block 305. At this time, the brush 307 cleans the dust adhered to the surface of the filter screen 4, completing the cleaning of the filter screen 4.

[0039] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
