Description

Technical Field

[0001] The invention relates to the technical field of ventilation devices, and in particular to a high-efficiency indoor ventilation and air exchange device. Background Art

[0002] Ventilation equipment is a series of equipment used to improve indoor air quality, maintain air circulation and meet specific environmental requirements. Relying on mechanical air supply and air induction, a fresh air flow field is forced to form in the system. That is, fresh air from the outside is sent into the room through one side, and the dirty air in the room is discharged on the other side, forming a "fresh air flow field" in the room to meet the demand for continuous fresh indoor air. In indoor efficient ventilation equipment, the removal of impurities in the air is a key step to ensure air quality. Its function is to remove particulate matter, microorganisms and aerosols in the air by physical or chemical means. Filter bags are often used to remove impurities in the air. When air passes through the filter bag, the impurities are intercepted by the surface of the filter bag, and gas-solid separation is achieved by screening, inertial collision, electrostatic adsorption and other effects.

[0003] For example, the invention patent with the announcement number CN111412569B provides a ventilation device for indoor air purification in buildings. Through the ventilation device, a filter can be used to filter air twice, thereby improving the filtering efficiency. However, the ventilation device cannot actively clean the filter during use, and cannot remove the fine dust attached to it, resulting in incomplete cleaning, thereby affecting the filtering effect of the filter.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Reference Figures 1 to 14 As shown, an indoor high-efficiency ventilation device provided by an embodiment of the present invention includes a bracket 110, an outer cylinder 100, a filtering mechanism, an air intake mechanism and an adjusting mechanism, wherein the outer cylinder 100 is fixedly arranged on the bracket 110 and the outer cylinder 100 is arranged horizontally. The filtering mechanism includes a first filter cartridge 200 and a second filter cartridge 210 arranged in the outer cylinder 100. The first filter cartridge 200 and the second filter cartridge 210 are both coaxial with the outer cylinder 100, and the second filter cartridge 210 is located in the first filter cartridge 200.

[0041] The two ends of the first filter cartridge 200 are the first end and the second end, respectively. The two ends of the second filter cartridge 210 are the third end and the fourth end, respectively. The first end of the first filter cartridge 200 and the third end of the second filter cartridge 210 are at the same end, and the second end of the first filter cartridge 200 and the fourth end of the second filter cartridge 210 are at the same end. The airflow provided by the air intake mechanism enters between the first filter cartridge 200 and the second filter cartridge 210 from the first end of the first filter cartridge 200, and is filtered by the first filter cartridge 200 and the second filter cartridge 210 and then discharged from the outside of the first filter cartridge 200 and the inside of the second filter cartridge 210.

[0042] The first filter cartridge 200 and the second filter cartridge 210 are both deformable. The filter mechanism has a first state and a second state. The first state of the filter mechanism is that the diameter of the first end of the first filter cartridge 200 is greater than the diameter of the second end of the first filter cartridge 200. The diameter of the third end of the second filter cartridge 210 is smaller than the diameter of the fourth end of the second filter cartridge 210. The second state of the filter mechanism is that the diameters of the first end and the second end of the first filter cartridge 200 are the same, and the diameters of the third end and the fourth end of the second filter cartridge 210 are the same.

[0043] The regulating mechanism controls the amount of air entering between the first filter cartridge 200 and the second filter cartridge 210 so that the filtering mechanism completes the mutual transition between the first state and the second state. When the air volume is large, the filtering mechanism changes from the first state to the second state, and when the air volume is small, the filtering mechanism changes from the second state to the first state, thereby squeezing the dust on the first filter cartridge 200 and the second filter cartridge 210.

[0044] In the initial state, the filter mechanism is in the first state. The airflow provided by the air intake mechanism enters between the first filter cartridge 200 and the second filter cartridge 210 from the first end of the first filter cartridge 200 and is filtered by the first filter cartridge 200 and the second filter cartridge 210 before being discharged.

[0045] The amount of air entering between the first filter cartridge 200 and the second filter cartridge 210 is controlled by the regulating mechanism. When the air volume is large, the wind blows the second end of the first filter cartridge 200 and the fourth end of the second filter cartridge 210 away from each other, so that the filtering mechanism is changed from the first state to the second state. The fourth end of the second filter cartridge 210 shrinks inward, and the dust on the second filter cartridge 210 is squeezed, which facilitates the collection of dust. The second filter plate 211 is preliminarily cleaned, which helps to improve the filtering effect. The second end of the first filter cartridge 200 expands outward, thereby increasing the filtering area of ​​the first filter cartridge 200, preventing the filtering efficiency from being affected by the reduction of the filtering area of ​​the second filter cartridge 210, thereby ensuring the filtering effect. When the air volume is small, the regulating mechanism drives the filtering mechanism to change from the second state to the first state. The first state and the second state of the filtering mechanism are constantly switched, and the first filter cartridge 200 and the second filter cartridge 210 are automatically cleaned respectively without affecting the filtering effect of the filtering mechanism, thereby improving the filtering efficiency.

[0047] When the second end of the first filter cartridge 200 contracts, the two adjacent first filter plates 201 squeeze each other, thereby squeezing out the dust. When the fourth end of the second filter cartridge 210 contracts, the two adjacent second filter plates 211 squeeze each other, thereby squeezing out the dust.

At this time, the sliding shaft 203 slides in the first inclined groove 701. Since the first inclined groove 701 is inclined, when the sliding shaft 203 slides in the first inclined groove 701, it pushes the sliding block 700 to slide in the first arc groove 312, and the sliding block 700 squeezes the first telescopic rod 710 and the third spring 720.

[0064] The third spring 720 squeezes the first blocking ring 310 and pushes the first blocking ring 310 to rotate, so that each fourth through hole 311 on the first blocking ring 310 is used to communicate with a second through hole 302. Gas passes through the fourth through hole 311 and the second through hole 302 to blow out the dust in the filter channel.

[0065] In this embodiment, the cleaning mechanism also includes a locking assembly, which includes a second telescopic rod 800 and a block 810. The second telescopic rod 800 is fixedly arranged on the first blocking ring 310, and the second telescopic rod 800 is arranged along the axial direction of the first blocking ring 310. The block 810 is fixedly arranged on the second telescopic rod 800, and a first inclined surface is arranged on the block 810. A limiting groove 305 is provided on the sliding bearing plate 300, and the block 810 is arranged in the limiting groove 305, and a second inclined surface that abuts against the first inclined surface is arranged in the limiting groove 305. In the initial state, the block 810 is in the limiting groove 305. When the sliding block 700 slides in the first arc groove 312, the third spring 720 squeezes the first blocking ring 310. When the third spring 720 is compressed to enable the block 810 to be disengaged from the limiting groove 305, the third spring 720 quickly extends and pushes the first blocking ring 310 to rotate.

[0066] In this embodiment, the cleaning mechanism further includes a dust collection box 900, which is fixedly disposed on the sliding bearing plate 300 and is connected to the second through hole 302. A plurality of third filter holes are provided on the dust collection box 900. After the fourth through hole 311 is connected to the second through hole 302, the dust in the filter channel is blown into the dust collection box 900, thereby completing the cleaning of the first filter cartridge 200 and the second filter cartridge 210 and the collection of dust.

[0067] Working process: In the initial state, the filter mechanism is in the first state, the fourth through hole 311 on the first blocking ring 310 and the second through hole 302 of the sliding bearing plate 300 are not connected. The block 810 is in the limiting groove 305.

[0068] The motor 540 is started, and the motor 540 drives the fan 550 to rotate through the rotating shaft 500. When the fan 550 rotates, the airflow from the first end to the second end of the first filter cartridge 200 is introduced into the outer cylinder 100. The gas enters the outer cylinder 100 and enters the filter channel through the first annular channel 121. Then, the gas is filtered by the first filter cartridge 200 and the second filter cartridge 210. The gas filtered by the first filter cartridge 200 is discharged from the outer cylinder 100 through the plurality of third through holes 303. The gas filtered by the second filter cartridge 210 is discharged from the outer cylinder 100 through the first through hole 301.

[0069] When the rotating shaft 500 rotates, the planetary gear 530 is driven to rotate through the central gear, and then the second blocking ring 410 is driven to rotate through the gear ring 520. When the second blocking ring 410 rotates, the overlapping area of ​​the first adjustment hole 401 and the second adjustment hole is continuously changed, thereby continuously changing the flow rate of the gas entering the filter channel. The overlapping area of ​​the first adjustment hole 401 and the second adjustment hole gradually decreases and then gradually increases.

[0070] When more gas enters the filter channel, the gas pushes the first slider 202 to move in the first slide groove 304 in a direction away from the second filter cartridge 210, and the first damping rod 600 and the first spring 610 are compressed. The gas also pushes the second slider 212 to move in the first slide groove 304 in a direction away from the first filter cartridge 200, and the second damping rod 620 and the second spring 630 are compressed. The filter mechanism changes from the first state to the second state.

[0071] The fourth end of the second filter cartridge 210 contracts inward, and the two adjacent second filter plates 211 squeeze each other, thereby squeezing the dust, facilitating the collection of dust, and preliminarily cleaning the second filter plates 211, which helps to improve the filtering effect. The second end of the first filter cartridge 200 expands outward, and the angle between the two adjacent first filter plates 201 increases, thereby increasing the filtering area of ​​the first filter cartridge 200, preventing the filtering efficiency from being affected due to the reduction of the filtering area of ​​the second filter cartridge 210, thereby ensuring the filtering effect.

[0072] Afterwards, when the gas entering the filter channel is less, the first spring 610 and the second spring 630, the first damping rod 600 and the second damping rod 620 are reset, so that the filter mechanism changes from the second state to the first state. The second end of the first filter cartridge 200 contracts inward, and the two adjacent first filter plates 201 squeeze each other, thereby squeezing the dust, facilitating the collection of dust, and preliminarily cleaning the first filter plates 201. The first state and the second state of the filter mechanism are continuously switched, and the first filter cartridge 200 and the second filter cartridge 210 are cleaned respectively.

[0073] When the first filter cartridge 200 and the second filter cartridge 210 are seriously clogged, the air pressure in the filter channel increases, and the gas blows the second end of the first filter cartridge 200 to expand outward, and the fourth end of the second filter cartridge 210 to shrink inward. At this time, the filter mechanism is in the second state.

[0074] When the first slider 202 slides in the first slide groove 304, the sliding shaft 203 slides in the first inclined groove 701. Since the first inclined groove 701 is inclined, the sliding shaft 203 pushes the sliding block 700 to slide in the first arc groove 312 when sliding in the first inclined groove 701, and the sliding block 700 squeezes the first telescopic rod 710 and the third spring 720.

[0075] The third spring 720 squeezes the first sealing ring 310. When the third spring 720 is compressed to the point where the block 810 can be disengaged from the limiting groove 305, the third spring 720 quickly extends and pushes the first sealing ring 310 to rotate, so that each fourth through hole 311 on the first sealing ring 310 is used to communicate with a second through hole 302.

[0076] The gas passes through the fourth through hole 311 and the second through hole 302, and blows the dust in the filter channel into the dust collection box 900, thereby completing the cleaning of the first filter cartridge 200 and the second filter cartridge 210. In addition, because the filter mechanism is slowly transformed from the second state to the first state under the action of the first damping rod 600 and the second damping rod 620, the reset of the sliding block 700 is relatively slow, which is enough to blow the dust in the filter channel into the dust collection box 900.

[0077] When the filtering mechanism is in the second state, the first filter cartridge 200 and the second filter cartridge 210 are arranged in parallel. Due to the Bernoulli principle, the first filter cartridge 200 and the second filter cartridge 210 vibrate, thereby cleaning the dust on the first filter cartridge 200 and the second filter cartridge 210.

[0078] When the first filter cartridge 200 and the second filter cartridge 210 are gradually cleaned and the filter mechanism begins to change from the second state to the first state, the sliding shaft 203 drives the sliding block 700 to reset, and the sliding block 700 drives the first sealing ring 310 to reset and rotate through the third spring 720, so that the fourth through hole 311 and its corresponding second through hole 302 are no longer connected.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
