Technical Field

[0001] The utility model relates to the technical field of exhaust and ventilation, in particular to a high-efficiency exhaust device with a filtering function. Background Art

[0002] High-efficiency exhaust devices are typically used to remove polluted indoor air and bring in fresh air from outside. These devices create negative or positive pressure to expel indoor air while simultaneously drawing in fresh air, achieving ventilation. However, during this process, the exhaust device's fan blades tend to absorb large amounts of dust. To prevent this dust from affecting the device's operational stability and ventilation efficiency, a dust filter is often installed at the front end of the fan's air intake. However, the filter cover of the fan that draws outdoor air into the room is often installed on the outside of the wall, making it difficult for users to clean. Utility Model Content

[0003] In order to overcome the problem of dust being adsorbed on the fan blades during the operation of the exhaust device and affecting the stability and ventilation efficiency of the device, a dust filter cover is often installed at the front end of the fan's air intake direction. However, the filter cover of the fan that introduces outdoor air into the room is often installed on the outside of the wall through the wall, making it difficult for users to clean it.

[0006] Preferably, the ventilation assembly includes a first side panel, a second side panel, a first frame panel, a second frame panel, a third frame panel, a positioning frame, a fourth frame panel, an upper air duct, a first two-way fan, a lower air duct, and a second two-way fan; a second side panel is provided on one side of the first side panel; the first side panel and the second side panel are connected to each other via bolts via the first frame panel; a second frame panel is provided at the lower end of the first frame panel; a third frame panel is provided at the front end of the first frame panel; a positioning frame is connected to the rear end of the third frame panel via bolts; and a fourth frame panel is provided at the lower end of the third frame panel. The first two-way fan operates in a forward direction so that outdoor air passes through the outer dust filter panel, the upper air duct, and the high-efficiency filter in sequence before entering the room. In this process, the outer dust filter panel filters dust in the outdoor air, and the high-efficiency filter filters the air more finely to improve the indoor air quality.

[0007] Preferably, an upper air duct is provided between the first and second frame plates; a first bidirectional fan is installed in the upper air duct; a lower air duct is provided between the second and fourth frame plates; a second bidirectional fan is installed in the lower air duct. The second bidirectional fan operates in a forward direction so that indoor air passes through the inner dust filter plate, the lower air duct, and the insect screen in sequence before being discharged outdoors. During this process, dust in the indoor air is filtered by the inner dust filter plate, thereby significantly reducing the probability of dust in the air being adsorbed on the fan blades, thereby ensuring the stability and ventilation efficiency of the device during operation and reducing the probability of device failure.

[0008] Preferably, the filtering and cleaning assembly includes a high-efficiency filter, an inner dust filter plate, an insect-proof net, an electric slide rail, a first connecting rod, a brush plate, an ultrasonic vibrator, an outer dust filter plate, a first slide groove, and soft bristles; a high-efficiency filter is inserted into the upper end of the positioning frame; the upper end of the fourth frame plate is connected to the inner dust filter plate by bolts; the rear end of the first two-way fan is provided with an electric slide rail that is bolted to the second frame plate; the electric slide rail is slidably connected to the first connecting rod via an electric slider. The electric slide rail uses the electric slider and the first connecting rod to make the brush plate brush up and down the rear end surface of the outer dust filter plate to brush off the dust on the outer dust filter plate, and uses the ultrasonic vibrator to make the brush plate vibrate at a high frequency, and the brush plate transmits the high-frequency vibration to the outer dust filter plate to shake off the dust, thereby increasing the dust removal efficiency.

[0009] Preferably, the rear end of the first connecting rod is bolted to a brush plate; the rear end of the brush plate is fixedly connected to an ultrasonic vibrator; the rear end of the electric slide rail is provided with an outer dust filter plate bolted to the second frame plate; first chutes are formed on both sides of the outer dust filter plate, and the first connecting rod passes through the first chutes; soft bristles are fixed in the first chutes. The soft bristles are used to reduce air and dust passing through the first chutes.

When removing dust from the outer dust filter plate, the downward pressing block causes the three slide plates to be displaced together under the action of the synchronous belt, so that the baffles in the first frame plate and the third frame plate are changed from retracted to leaking, and the baffle in the second frame plate is changed from exposed to retracted, so as to change the frame structure inside the device, so that the upper air duct and the lower air duct are connected up and down, and the high-efficiency filter and the inner dust filter plate are isolated from the upper air duct and the lower air duct. Then the first two-way fan and the second two-way fan operate in the opposite direction to make the outdoor air pass through the insect-proof net, the downwind duct, the upper air duct and the outer dust filter plate in turn, so as to blow the brushed and shaken dust away to a distance, thereby further improving the dust removal efficiency. In this process, because the high-efficiency filter and the inner dust filter plate have been isolated, and the air permeability of the insect-proof net is higher than that of the high-efficiency filter, the wind force when blowing off the dust on the outer dust filter plate can be enhanced to further improve the dust removal strength. At the same time, in this process, because the high-efficiency filter and the inner dust filter plate have been isolated, it can also prevent the dust on the inner dust filter plate from being blown off and causing pollution to the indoor environment.

[0011] Preferably, baffles are slidably connected to the first frame plate, the second frame plate and the third frame plate, and in normal state, the baffles in the first frame plate and the third frame plate are retracted, while the baffle in the second frame plate is exposed; a second connecting rod is fixedly connected to one side of the baffle; a slide is fixedly connected to one side of the second connecting rod, and the slides slide in the second slide groove; a shift block is fixedly connected to the front end of the frontmost slide, and the shift block slides in the fourth slide groove.

[0012] Beneficial effects of the utility model:

[0013] 1.

The device can also automatically and efficiently remove dust on the external dust filter, thereby improving the user experience of the device.

[0014] 2. The electric slide rail uses the electric slider and the first connecting rod to make the brush plate move up and down to brush the rear end surface of the outer dust filter plate to brush off the dust on the outer dust filter plate. The ultrasonic vibrator makes the brush plate vibrate at a high frequency, and the brush plate transmits the high-frequency vibration to the outer dust filter plate to shake off the dust, thereby increasing the dust removal efficiency and making it easier to clean the dust on the outer filter cover.

[0015] 3. When removing dust from the outer dust filter plate, press down the shift block to displace the three slides together under the action of the synchronous belt, so that the baffles in the first frame plate and the third frame plate change from retracted to leaking, and the baffle in the second frame plate changes from exposed to retracted, so as to change the internal frame structure of the device, so that the upper air duct and the lower air duct are connected up and down, and the high-efficiency filter and the inner dust filter plate are isolated from the upper air duct and the lower air duct. Then the first two-way fan and the second two-way fan operate in reverse to make the outdoor air pass through the insect screen, the lower air duct, the upper air duct and the outer dust filter plate in turn, so as to blow the brushed and shaken dust away to a distance, thereby further improving the dust removal efficiency.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See also Figure 1-4The present invention provides an embodiment of a high-efficiency exhaust device with a filtering function, comprising a ventilation assembly 1, a filter-cleaning assembly 2, and a redirecting assembly 3.

The redirecting assembly 3 is used to modify the internal frame structure of the device to change the air flow path and assist in dust removal. The ventilation assembly 1 includes a first side panel 101, a second side panel 102, a first frame panel 103, a second frame panel 104, a third frame panel 105, a positioning frame 106, a fourth frame panel 107, an upper air duct 108, a first two-way fan 109, a lower air duct 110, and a second two-way fan 111; the second side panel 102 is provided on one side of the first side panel 101; the first side panel 101 and the second side panel 102 are connected to each other via bolts via the first frame panel 103; the second frame panel 104 is provided at the lower end of the first frame panel 103; the third frame panel 105 is provided at the front end of the first frame panel 103; the rear end of the third frame panel 105 is connected to the positioning frame 106 via bolts; and the fourth frame panel 107 is provided at the lower end of the third frame panel 105. The first bidirectional fan 109 operates in a forward direction, allowing outdoor air to pass through the outer dust filter plate 208, the upper air duct 108, and the high-efficiency filter 201 before entering the room. During this process, the outer dust filter plate 208 filters dust from the outdoor air, and the high-efficiency filter 201 further filters the air, thereby improving the indoor air quality. An upper air duct 108 is provided between the first frame plate 103 and the second frame plate 104; the first bidirectional fan 109 is installed in the upper air duct 108; a lower air duct 110 is provided between the second frame plate 104 and the fourth frame plate 107; and a second bidirectional fan 111 is installed in the lower air duct 110. The second bidirectional fan 111 operates in a forward direction, allowing indoor air to pass through the inner dust filter plate 202, the lower air duct 110, and the insect screen 203 before being discharged outdoors. During this process, the inner dust filter plate 202 filters dust from the indoor air, significantly reducing the probability of dust in the air being adsorbed on the fan blades, thereby ensuring the stability and ventilation efficiency of the device during operation and reducing the probability of device failure.The filtering and cleaning component 2 includes a high-efficiency filter 201, an inner dust filter plate 202, an insect-proof net 203, an electric slide rail 204, a first connecting rod 205, a brush plate 206, an ultrasonic vibrator 207, an outer dust filter plate 208, a first slide groove 209, and soft bristles 210; the upper end of the positioning frame 106 is inserted with a high-efficiency filter 201; the upper end of the fourth frame plate 107 is connected to the inner dust filter plate 202 by bolts; the rear end of the first bidirectional fan 109 is provided with an electric slide rail 204 bolted to the second frame plate 104; the first connecting rod 205 is slidably connected to the electric slide rail 204 through an electric slider. The electric slide 204, through the electric slider and the first connecting rod 205, causes the brush plate 206 to brush the rear end surface of the outer dust filter plate 208 up and down, brushing dust off the outer dust filter plate 208. The ultrasonic vibrator 207 causes the brush plate 206 to vibrate at a high frequency, which is then transmitted to the outer dust filter plate 208 to shake off dust, thereby increasing dust removal efficiency. The rear end of the first connecting rod 205 is bolted to the brush plate 206; the rear end of the brush plate 206 is fixedly connected to the ultrasonic vibrator 207. The rear end of the electric slide 204 is provided with the outer dust filter plate 208, which is bolted to the second frame plate 104. First chutes 209 are defined on both sides of the outer dust filter plate 208, through which the first connecting rod 205 passes. Soft bristles 210 are fixedly attached to each of the first chutes 209. The soft bristles 210 are used to reduce the amount of air and dust that passes through the first chutes 209.

[0026] See also Figure 5-7In this embodiment, the redirection component 3 includes a second slide groove 301, a rotating shaft 302, a fixed cover 303, a fourth slide groove 304, a synchronous belt 305, a baffle 306, a second connecting rod 307, a slide plate 308, and a shift block 309; three second slide grooves 301 are opened on the first side plate 101; six rotating shafts 302 are rotatably connected to the outer side of the first side plate 101; one side of the rotating shaft 302 is rotatably connected to the fixed cover 303; the front end of the fixed cover 303 is opened with a fourth slide groove 304; and the rotating shaft 302 is rotatably connected to the synchronous belt 305. When removing dust from the outer dust filter plate 208, the shift block 309 is pressed downward to cause the three slide plates 308 to move together under the action of the synchronous belt 305, so that the baffles 306 in the first frame plate 103 and the third frame plate 105 are changed from retracted to leaking, and the baffles 306 in the second frame plate 104 are changed from exposed to retracted, so as to change the internal frame structure of the device, so that the upper air duct 108 and the lower air duct 110 are connected up and down, and the high-efficiency filter 201 and the inner dust filter plate 202 are isolated from the upper air duct 108 and the lower air duct 110. Then the first two-way fan 109 and the second two-way fan 111 are rotated in reverse to make the outdoor air pass through the insect screen 20 in turn. 3. The downwind duct 110, the upwind duct 108 and the outer dust filter plate 208 are used to blow the dust that has been brushed off and shaken off to a distant place, thereby further improving the dust removal efficiency. In this process, because the high-efficiency filter 201 and the inner dust filter plate 202 have been isolated, and the air permeability of the insect-proof net 203 is higher than that of the high-efficiency filter 201, the wind force when blowing off the dust on the outer dust filter plate 208 can be enhanced to further improve the dust removal effect. At the same time, in this process, because the high-efficiency filter 201 and the inner dust filter plate 202 have been isolated, the dust on the inner dust filter plate 202 can be prevented from being blown off and causing pollution to the indoor environment. Baffles 306 are slidably connected to the first frame plate 103, the second frame plate 104, and the third frame plate 105. In normal state, the baffles 306 in the first frame plate 103 and the third frame plate 105 are retracted, while the baffle 306 in the second frame plate 104 is exposed; a second connecting rod 307 is fixedly connected to one side of the baffle 306; a slide 308 is fixedly connected to one side of the second connecting rod 307, and the slides 308 slide in the second slide groove 301; a shift block 309 is fixedly connected to the front end of the frontmost slide 308, and the shift block 309 slides in the fourth slide groove 304.

[0027] When in operation, the first bidirectional fan 109 rotates in the forward direction to allow outdoor air to pass through the outer dust filter plate 208, the upper air duct 108 and the high-efficiency filter 201 in sequence before entering the room. During this process, the outer dust filter plate 208 filters dust from the outdoor air, and the high-efficiency filter 201 filters the air more finely to improve the indoor air quality.

[0028] At the same time, the second bidirectional fan 111 rotates in the forward direction so that the indoor air passes through the inner dust filter plate 202, the downwind duct 110, and the insect screen 203 in sequence before being discharged outdoors. During this process, the inner dust filter plate 202 filters the dust in the indoor air, thereby significantly reducing the probability of dust in the air being adsorbed on the fan blades, thereby ensuring the stability and ventilation efficiency of the device during operation and reducing the probability of device failure.

[0029] When cleaning the filter cover on the outside of the wall, the electric slide rail 204 uses the electric slider and the first connecting rod 205 to make the brush plate 206 brush the rear end surface of the outer dust filter plate 208 up and down to brush off the dust on the outer dust filter plate 208, and the ultrasonic vibrator 207 causes the brush plate 206 to vibrate at a high frequency, and the brush plate 206 transmits the high-frequency vibration to the outer dust filter plate 208 to shake off the dust, thereby increasing the dust removal efficiency. At the same time, the soft bristles 210 are used to reduce the air and dust passing through the first chute 209;

[0030] When removing dust from the outer dust filter plate 208, the shift block 309 is pressed downward to cause the three slide plates 308 to move together under the action of the synchronous belt 305, so that the baffles 306 in the first frame plate 103 and the third frame plate 105 are changed from retracted to leaking, and the baffles 306 in the second frame plate 104 are changed from exposed to retracted, so as to change the internal frame structure of the device, so that the upper air duct 108 and the lower air duct 110 are connected up and down, and the high-efficiency filter 201 and the inner dust filter plate 202 are isolated from the upper air duct 108 and the lower air duct 110. Then the first two-way fan 109 and the second two-way fan 111 are rotated in reverse to make the outdoor air pass through the insect screen 20 in turn. 3. The downwind duct 110, the upwind duct 108 and the outer dust filter plate 208 are used to blow the dust that has been brushed off and shaken off to a distant place, thereby further improving the dust removal efficiency. In this process, because the high-efficiency filter 201 and the inner dust filter plate 202 have been isolated, and the air permeability of the insect-proof net 203 is higher than that of the high-efficiency filter 201, the wind force when blowing off the dust on the outer dust filter plate 208 can be enhanced to further improve the dust removal effect. At the same time, in this process, because the high-efficiency filter 201 and the inner dust filter plate 202 have been isolated, the dust on the inner dust filter plate 202 can be prevented from being blown off and causing pollution to the indoor environment.

[0031] Through the above steps, a dust filter and cleaning mechanism and an air duct reorganization mechanism are set up, so that the device can prevent dust in the air from being adsorbed on the fan blades during the exhaust and ventilation process of the room, so as to ensure the stability and working efficiency of the device during operation, reduce the probability of device failure, and allow the device to efficiently remove dust on the outer dust filter by itself, so as to improve the user experience of the device.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
