DETAILED DESCRIPTION

[0040] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that 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 making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 14 The present invention provides a technical solution: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a circulation mechanism 2, which is used to process the change of external wind pressure, and a housing 1 is fixedly installed on the outer side of the circulation mechanism 2;

[0042] A filter mechanism 7, the filter mechanism 7 is used to filter impurities in the wind;

[0043] The wind control mechanism 8 is used to control the wind flow rate, and the two ends of the wind control mechanism 8 are symmetrically connected with the wind guide plates 6;

[0044] The outer side of the casing 1 is fixedly connected with a No. 1 outlet pipe 3 and a No. 2 outlet pipe 5 , and an exhaust fan 4 is fixedly installed inside the casing 1 . An air induced plate 6 , a filtering mechanism 7 and an air control mechanism 8 are all fixedly installed inside the casing 1 .

[0045] The circulation mechanism 2 includes a blower 21, which is fixedly installed inside the casing 1. The circulation mechanism 2 also includes a bell tube 22, the inner end of the bell tube 22 is fixedly connected to the blower 21, the outer side of the bell tube 22 is fixedly connected to a motor 23, the output end of the motor 23 is connected to a screw rod 24 through a coupling, the end of the screw rod 24 away from the motor 23 is connected to the inside of the bell tube 22 through a bearing, the outer side of the screw rod 24 is threadedly connected to an inclined slider 25, the top of the inclined slider 25 is fixedly connected to a folded tube 29, the end of the folded tube 29 away from the inclined slider 25 is plugged with a sleeve 20, the end of the inclined slider 25 away from the screw rod 24 is fixedly connected to an arc tube 26, the end of the arc tube 26 away from the inclined slider 25 is fixedly connected to a rubber tube 27, and the two ends of the arc tube 26 are respectively fixedly connected to elastic sheets 28, so that the outdoor air is started by starting the blower 21. The flow will form wind and enter the rubber tube 27, but before that, the motor 23 needs to be started first, so that the screw rod 24 connected to the output end of the motor 23 through the coupling will rotate forward, and then the inclined slider 25 threadedly connected to the outer side of the screw rod 24 will move upward along the screw rod 24, and then the arc tube 26 fixedly connected to the other end of the inclined slider 25 will move outward with the rubber tube 27 and expand, wherein the rubber tube 27 is connected to the arc tube 26. At this time, the elastic sheets 28 fixedly connected to the two ends of the arc tube 26 will be stressed and have a tendency to stretch on both sides, causing the space surrounded by several arc tubes 26 and the elastic sheets 28 to continue to expand, and at the same time, the inner diameter of the rubber tube 27 is also continuously expanding. Therefore, the wind sent in by the blower 21 will pass through the rubber tube 27, the arc tube 26 and the horn tube 22 in turn, and finally enter the casing 1. In summary, the inner diameter of the gas transmission pipeline can be regulated to achieve pressure regulation: it helps to adjust the gas pressure in the pipeline to keep it in an appropriate range and ensure the stability of system operation; at the same time, when the environment is in summer, the inner diameter of the circulation pipe can be increased. At this time, when the gas flows from the area with a large inner diameter through the area with a smaller inner diameter, the space suddenly becomes smaller, and the smaller inner diameter will increase the gas flow rate. According to the principles of thermodynamics, the increase in the kinetic energy of the gas is often accompanied by a decrease in internal energy, which is manifested as a drop in temperature. Therefore, even if it is not hot air, heat exchange can regulate the temperature of the incoming air to a certain extent, making it closer to the indoor temperature, reducing the impact on the indoor temperature, and improving comfort. In addition, the heat exchange process itself can also play a certain energy-saving role. Compared with directly introducing untreated air, it can reduce the load fluctuation of the air-conditioning system.

[0046] like Figure 6 and Figure 7As shown, the wind control mechanism 8 includes a perforated plate 81, both ends of the perforated plate 81 are fixedly connected to the air induced plate 6, the perforated plate 81 is fixedly connected to the inside of the casing 1, the inside of the perforated plate 81 is fixedly connected to a support 82, the inside of the support 82 is rotatably connected to a limiting plate 83, the outside of the limiting plate 83 is fixedly connected to a spring 84, the top of the perforated plate 81 is fixedly connected to a top rail 85, the inside of the top rail 85 is slidably adapted to a moving block 86, the bottom of the moving block 86 is fixedly connected to a push rod 87, the outside of the push rod 87 is squeezed and adapted to the spring 84, and the moving block The top of the housing 1 is fixedly connected with a top rod 88, the top of the top rod 88 is fixedly connected with a rod sleeve 89, the top of the rod sleeve 89 is fixedly connected with a pull handle 80, and the two sides of the pull handle 80 are symmetrically provided with a sticker 801, the sticker 801 is fixedly connected to the top of the housing 1, and the outer side of the pull handle 80 is fixedly connected with a leak-proof spring sheet 802, and the end of the leak-proof spring sheet 802 away from the pull handle 80 is fixedly connected to the housing 1, wherein the fixed inner plate 74 divides the inner cavity of the housing 1 into four spaces, and the wind sent in by the blower 21 will enter the first chamber, and then The wind in the first chamber will hit the flow limiting plate 83. At this time, the handle 80 can be manually pushed, so that the rod sleeve 89 fixedly connected to the bottom of the handle 80 will move forward and backward with the push rod 88, wherein the leakproof spring piece 802 fixedly connected to the outer side of the handle 80 is elastic and leakproof, and the shifting block 86 fixedly connected to the bottom of the push rod 88 will move forward and backward with the push rod 87, and the push rod 87 will squeeze the spring 84 outward or move away, wherein when the push rod 87 moves away from the spring 84, The spring 84 will cause the flow limiting plate 83 to deflect inward through its own outward elastic force, causing the gap between the two flow limiting plates 83 to become larger. Similarly, when the push rod 87 approaches and squeezes the spring 84, the gap between the two flow limiting plates 83 will become smaller. The above-mentioned function is to regulate the flow rate of wind entering the filter mechanism 7. When the wind speed is low, the outdoor air and the indoor air can be fully exchanged with each other. At the same time, when the wind speed is high, the exchange rate between the outdoor and indoor air can be accelerated, thereby achieving the effect of rapid ventilation.

[0047] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, the filtering mechanism 7 includes a placement frame 71, which is fixedly connected to the inside of the casing 1, and a heat exchange core 72 is arranged inside the placement frame 71. A No. 1 clamping component 73 is fixedly connected to the corner of the outer side of the placement frame 71, and a fixed inner plate 74 is arranged at the end of the No. 1 clamping component 73 away from the placement frame 71. The fixed inner plate 74 is fixedly connected to the inside of the casing 1, and the outer side of the No. 1 clamping component 73 is slidably adapted with a filtering component 75. A frame sticker 76 is fixedly connected to the outer side of the placement frame 71, and an outer slide frame 77 is inserted into the outer side of the frame sticker 76. A through hole 79 is provided in the center, and the outer side of the outer slide 77 is slidably adapted to be equipped with a filter assembly 75. The end of the outer slide 77 away from the filter assembly 75 is plugged with a limited fixed plug plate 78, and the interior of the limited fixed plug plate 78 is fixedly connected to a No. 1 magnet 70, and the end of the No. 1 magnet 70 away from the limited fixed plug plate 78 is provided with a No. 2 magnet 701, and the outer side of the No. 2 magnet 701 is fixedly connected to an inclined plug plate 702, which is slidably adapted to the interior of the limited fixed plug plate 78, wherein the inclined portion of the bottom end of the inclined plug plate 702 is squeezed and adapted to the outer slide 77, and before the outdoor wind is introduced The outer slide 77 needs to be inserted into the outer side of the frame sticker 76, wherein the outer slide 77 plays a role in limiting and supporting the filter assembly 75, and then the limiting fixing plate 78 is manually pressed downward, at this time, the inclined plate 702 slidingly adapted to the inside of the limiting fixing plate 78 will be squeezed by the outer slide 77, wherein the surface of the inclined plate 702 in contact with the outer slide 77 is an inclined surface, so the inclined plate 702 will be received into the inside of the limiting fixing plate 78, and when the inclined plate 702 moves to the position of the perforation 79, wherein the perforation 79 is opened on the outer slide 77, then in a Under the repulsive force between the No. 1 magnet 70 and the No. 2 magnet 701, the inclined plug plate 702 will pass through the through hole 79 and allow the outer slide 77 to fit and fix with the limiting plug plate 78. The material of the outer slide 77 has a shock-absorbing effect. Therefore, the outer slide 77 limits and reinforces the filter assembly 75 and the heat exchange core 72, thereby reducing the vibration effect. The top sliding adapter of the inclined plug plate 702 is equipped with a fixed block 703, and the top of the fixed block 703 is fixedly connected to a vertical rod 704, and the top of the vertical rod 704 is fixedly connected to the inside of the limiting plug plate 78.

[0048] The filter assembly 75 includes a detachable frame 751, the top of which is fixedly connected to a compensation frame 753, the detachable frame 751 is slidably adapted to the inner side of the outer slide frame 77, the outer side of the detachable frame 751 is fixedly connected to an open mesh 752, the interior of the detachable frame 751 is fixedly connected to an absorbent paper 754, and a filter screen 755 is arranged next to the absorbent paper 754. When the positions of the outer slide frame 77 and the limiting plug plate 78 are determined, the detachable frame 751 is inserted into the other end of the outer slide frame 77, wherein the interior of the detachable frame 751 is fixedly connected to the absorbent paper 754, and the filter screen 755 is arranged next to the absorbent paper 754. As the detachable frame 751 is inserted into the outer slide frame 77, the inner cavity of the filter screen 755 will overlap with the interlaced net 756, and then the wind gushing out from the flow limiting plate 83 will enter the detachable frame 751, and then the wind will pass through the absorbent paper 754 and the filter screen 755 inside the detachable frame 751 in sequence, wherein the absorbent paper 754 will absorb the moisture in the air, and the filter screen 755 will filter the impurities in the air until it enters the heat exchange core 72, wherein the heat exchange core 72 The purpose is to exchange heat between the filtered fresh air and the dirty air discharged from the room in the heat exchange core 72, so that the temperature of the fresh air discharged into the room will be closer to the indoor temperature. The filter 755 is fixedly installed inside the detachable frame 751. The inside of the filter 755 is slidably adapted to be interlaced with a mesh 756. The bottom of the interlaced mesh 756 is fixedly connected to a bottom plug 757. The bottom of the bottom plug 757 is fixedly connected to a flower plate 758. In addition, the electric push rod 759 can be started to make the flower plate 758 connected to the top of the electric push rod 759 8 will move the bottom plug 757 upward, and at this time the interlaced net 756 fixedly connected to the top of the bottom plug 757 will move upward and intersect with the filter 755, thereby causing the inner diameter of the filter hole on the filter 755 to decrease, thereby playing a role in regulating the degree of filtration.

The bottom plug 757 is respectively interlaced at the bottom of the casing 1 and the filter 755, and the bottom of the flower plate 758 is fixedly connected with an electric push rod 759.

[0049] Then the wind needs to pass through the detachable frame 751 on the other side of the heat exchange core 72, and finally be discharged from the fourth chamber inside the casing 1, and flow into the room from the No. 2 outlet pipe 5. The indoor air will enter the second chamber of the casing 1 through the exhaust fan 4, and at the same time, it also needs to pass through the heat exchange core 72 and the detachable frame 751 in turn, and finally enter the third chamber of the casing 1, and be discharged to the outside from the No. 1 outlet pipe 3.

[0050] When the present invention is in use: first, start the blower 21 to allow wind to enter the rubber tube 27, but before that, it is necessary to start the motor 23 first, so that the screw rod 24 connected to the output end of the motor 23 through the coupling rotates forward, and then the inclined slider 25 threadedly connected to the outer side of the screw rod 24 will move upward along the screw rod 24, and then the arc tube 26 fixedly connected to the other end of the inclined slider 25 will move outward with the rubber tube 27 and expand. At this time, the space surrounded by the arc tube 26 and the elastic sheet 28 will become larger, and at the same time, the inner diameter of the rubber tube 27 is also continuously expanding. Therefore, the wind sent in by the blower 21 will pass through the rubber tube 27, the arc tube 26 and the trumpet tube 22 in sequence, and finally enter the casing 1. The fixed inner plate 74 will divide the inner cavity of the casing 1 into four spaces, and the wind delivered by the blower 21 will enter the first chamber, and then the delivered wind will hit the flow limiting plate 83. At this time, the handle 80 can be manually pushed, so that the rod sleeve 89 fixedly connected to the bottom of the handle 80 will move forward and backward with the push rod 88, and at the same time, the shift block 86 fixedly connected to the bottom of the push rod 88 will move forward and backward with the push rod 87. At this time, the push rod 87 will squeeze the spring 84 outward or move away. When the push rod 87 is away from the spring 84, the spring 84 will use its own outward pop-up force to cause the flow limiting plate 83 to deflect inward, causing the gap between the two flow limiting plates 83 to become larger. Similarly, when the push rod 87 approaches and squeezes the spring 84, the gap between the two flow limiting plates 83 will become smaller, thereby realizing wind control.

[0051] Then the wind flowing out from the flow limiting plate 83 will enter the detachable frame 751, and then the wind will pass through the absorbent paper 754 and the filter net 755 inside the detachable frame 751 in turn until it enters the heat exchange core 72, and then the wind needs to pass through the detachable frame 751 on the other side of the heat exchange core 72, and finally be discharged from the fourth chamber inside the casing 1, and flow into the room from the No. 2 outlet pipe 5, and the indoor air will enter the second chamber of the casing 1 through the exhaust fan 4, and at the same time, it needs to pass through the heat exchange core 72 and the detachable frame 751 in turn, and finally enter the third chamber of the casing 1, and be discharged to the outside from the No. 1 outlet pipe 3.

Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
