Description

Technical Field

[0001] The present invention belongs to the technical field of animal epidemic prevention, and specifically refers to a veterinary animal epidemic prevention isolation device. Background Art

[0002] When veterinarians manage animals, they usually need to isolate animals for epidemic prevention. Whether it is newly added animals or diseased animals, physical isolation is required between them to prevent cross-infection of diseases.

[0003] In the prior art, the means usually adopted for animal epidemic prevention isolation is to put animals into a sealed box or cage. The space inside and outside the cage is connected, and it is impossible to effectively isolate the spread of diseases. It is difficult to achieve air circulation in the sealed box. Although some technologies have considered the above problems and designed isolation devices that can achieve internal and external ventilation effects, there are still many problems, such as:

[0004] Difficult to effectively isolate: During the process of animals entering and leaving the device, the device is in an open state, and the gas inside the device will overflow and interact with the outside air, resulting in the spread of diseases.

[0005] Poor ventilation effect: The inside of the device is in a state of one-way air circulation for a long time, and it is very easy to have ventilation dead corners, resulting in the accumulation of diseases, and overflowing from the device when the device is opened.

[0006] During ventilation, the germs in the air are difficult to be fully adsorbed and treated. The air entering the device and the air discharged from the device may both contain germs, leading to the spread of diseases. And because animal bodies are prone to shedding hair, the ventilation method is also likely to cause hair to float inside the device or even block the device, affecting the living environment of animals and the normal operation of the device. Summary of the Invention

[0007] In view of the above technical problems, the present invention provides a veterinary animal epidemic prevention isolation device, which overcomes the deficiencies of the prior art. The present invention adopts a special pipeline connection design and a clever pipeline switching control design. When the device is in an open state, an air flow isolation wall can be formed at the flat push type shielding door to prevent the air inside and outside the device from interacting. At the same time, the opening and closing actions of the flat push type shielding door are used to automatically switch the air flow channel inside the device, so that the air flow direction inside the device is automatically switched, effectively preventing the occurrence of ventilation dead corners inside the device, and effectively solving the problems of difficult effective isolation and poor ventilation effect in the prior art.

[0008] The technical solution adopted by the present invention is as follows: This solution provides a veterinary animal epidemic prevention and isolation device. The main structure of the device is an isolation box. A horizontal partition is fixedly installed on the inner wall of the isolation box. The horizontal partition divides the internal space of the isolation box into a power chamber and a receiving chamber from top to bottom. The power chamber is used to provide ventilation airflow and adjust the ventilation mode, and the receiving chamber is used to receive and isolate animals. A flat-push shielding door is provided on the front wall of the isolation box. The inner sides of both side walls of the isolation box are hollow. A ventilation filtration system, a ventilation component, and a gas distribution strip are provided on the upper wall of the horizontal partition. The ventilation component is horizontally slidably clamped on the upper wall of the gas distribution strip. The ventilation component and the gas distribution strip are dynamically connected through porous holes. The ventilation filtration system is connected to the ventilation component in a through manner. The two sides of the flat-push shielding door are respectively connected to the gas distribution strip in a through manner through pipelines. The hollow chambers inside the two side walls of the isolation box are respectively connected to the gas distribution strip in a through manner through pipelines. The ventilation filtration system provides power for the ventilation inside the receiving chamber and filters and purifies the gas entering and leaving the receiving chamber. The ventilation component cooperates with the gas distribution strip to realize the adjustment of the wind direction and air volume at the flat-push shielding door and inside the receiving chamber.

[0009] In this solution, the ventilation component includes an air distribution slide bar, an intake manifold, and an exhaust manifold. The air distribution slide bar is slidably clamped on the upper wall of the gas distribution strip. On the upper wall of the air distribution slide bar, a thin pipe A, a thin pipe B, a thick pipe A, a thick pipe B, a thin pipe C, and a thin pipe D are fixedly connected in sequence from left to right. The ends of the thin pipe A, the thin pipe B, the thick pipe A, the thick pipe B, the thin pipe C, and the thin pipe D close to the air distribution slide bar respectively penetrate the lower wall of the air distribution slide bar. The ends of the thin pipe A, the thick pipe B, and the thin pipe C far from the air distribution slide bar are fixedly connected to the intake manifold. The ends of the thin pipe B, the thick pipe A, and the thin pipe D far from the air distribution slide bar are fixedly connected to the exhaust manifold. A spring is connected between the side wall of the end of the air distribution slide bar and the inner wall of the isolation box. The air distribution slide bar is in sliding and fitting communication with the gas distribution strip.

[0010] As a further preference of this solution, the ventilation filtration system includes an intake main pipe, an exhaust main pipe, an intake pump, and an exhaust pump. The intake main pipe and the exhaust main pipe are arranged on the upper wall of the horizontal partition. The intake pump and the exhaust pump are respectively fixedly arranged on the inner side wall of the isolation box. The intake pump is connected to the middle of the intake main pipe, and the exhaust pump is connected to the middle of the exhaust main pipe. The intake volume of the intake pump is less than the exhaust volume of the exhaust pump, so as to form a negative pressure state inside the receiving chamber.

[0011] In order to enable the ventilation component to move and ensure that the gas path is always connected, the ends of the intake manifold and the intake main pipe close to each other are flexibly connected. The end of the intake manifold far from the corrugated expansion pipe A is closed. The ends of the exhaust manifold and the exhaust main pipe close to each other are flexibly connected. The end of the exhaust manifold far from the corrugated expansion pipe B is closed.

[0012] In order to achieve the isolation of the air curtain, in this solution, the push - type shielding door includes a fixed side door, a closing edge air strip, and a hollow door body. The fixed side door is fixedly arranged on the front wall of the isolation box, and the fixed side door is fixedly connected to one side wall of the isolation box. The closing edge air strip is fixedly arranged on the other side wall of the isolation box. The fixed side door is hollow, and the closing edge air strip is hollow. The hollow door body slides on the inner wall of the hollow chamber of the fixed side door. The sides of the hollow door body and the closing edge air strip facing each other are correspondingly arranged. When the hollow door body slides to the position of the closing edge air strip, the side of the hollow door body is inserted into the closing edge air strip and is hermetically clamped with the closing edge air strip. When the hollow door body slides into the interior of the fixed side door, the isolation box is in an open state, and the hollow chambers of the parts of the sides of the hollow door body and the closing edge air strip facing each other correspond to each other.

[0013] A pressure strip is fixedly arranged along the upper edge of the side wall of the hollow door body. The pressure strip corresponds to the air - distributing sliding strip. The air - distributing sliding strip is located on the movement path of the end of the pressure strip. This setting method transfers the movement effect of the hollow door body to the air - changing component, so that the air - changing component can achieve position switching, and then the switching of the gas path can be realized.

[0014] Furthermore, ventilation holes are arrayed and penetrate through both side walls of the isolation box inside the accommodation cavity, and the ventilation holes are communicated with the hollow chambers inside the side walls of the isolation box.

[0015] The beneficial effects obtained by the present invention are as follows:

[0016] (1) This solution uses the opening and closing actions of the equipment, combined with a special pipeline connection design and a clever pipeline switching control design, to automatically control the gas flow path and gas flow rate in the equipment, thereby realizing the automatic adjustment of the ventilation direction. An open - type isolation of the equipment is carried out by using an air curtain. When the equipment is in the open state, an air - flow isolation wall can be formed to prevent the air inside and outside the equipment from interacting. The opening and closing actions of the push - type shielding door are used to realize the automatic switching of the air - flow channel inside the equipment, so that the air - flow direction inside the equipment is automatically switched, effectively preventing the occurrence of ventilation dead - ends inside the equipment.

[0017] (2) When the push - type shielding door is closed, the ventilation air flow inside the isolation box is larger and the ventilation effect is better. When the push - type shielding door is opened, the ventilation direction inside the isolation box is automatically switched to prevent the occurrence of ventilation dead - ends, and the ventilation air flow becomes smaller. While the intensity of the air curtain at the push - type shielding door becomes larger and the shielding effect is better. Moreover, there is always an air curtain from the start of the opening until the closing of the push - type shielding door. Therefore, the inside and outside of the isolation box can be shielded and isolated throughout the process.

[0018] (3) The switching of the air flow state of the whole equipment can be realized only by the pushing effect of the hollow door body on the air distribution slide bar, and the docking relationship between the air exchange component and the gas distribution strip is switched, so as to quickly realize the air path switching and air flow distribution, which not only changes the air flow direction, but also changes the air flow volume, making the operation more convenient, and can achieve the effect of automatic shielding and reversing ventilation without any control system;

[0019] (4) When the horizontal push shielding door is closed, the thin tube A is connected to the door tube A, the thin tube B is connected to the door tube B, the thick tube A is connected to the box tube A, and the thick tube B is connected to the box tube B, so that a directional ventilation airflow is formed inside the receiving cavity. When the horizontal push shielding door is opened, the thick tube A is connected to the door tube A, the thick tube B is connected to the door tube B, the thin tube C is connected to the box tube A, and the thin tube D is connected to the box tube B, so that a reverse directional ventilation airflow is formed inside the receiving cavity. At the same time, a strong airflow curtain is formed at the horizontal push shielding door to achieve open isolation and prevent air interaction between the inside and outside of the equipment.

[0020] (5) The spiral filter plug-in changes the gas flow path into a spiral shape, so that impurities such as aerosol particles in the gas can collide with the inner wall of the spiral filter plug-in, and achieve efficient adsorption and purification of the gas. The intake filter valve and the exhaust filter valve filter and collect large particles of impurities and animal hair in the intake manifold and the exhaust manifold respectively, and cleaning is more convenient.

A spring 617 is connected between the side wall of the end part of the air distribution slide bar 61 and the inner wall of the isolation box 1.

[0036] As Figures 1 - 6As shown in the figure, a support A 21 and a support B 22 are fixedly arranged on the upper wall of the horizontal partition plate 2. The ventilation and filtration system 5 includes an intake main pipe 51, an exhaust main pipe 52, an intake pump 53 and an exhaust pump 54. The two ends of the intake main pipe 51 respectively penetrate and are fixedly arranged on the side walls of the support A 21 and the support B 22.

The intake volume of the intake pump 53 is less than the exhaust volume of the exhaust pump 54, so as to form a negative pressure state inside the accommodation cavity 4. A corrugated expansion pipe A 621 is fixedly communicated between the mutually approaching ends of the intake connection pipe 62 and the intake main pipe 51. The intake connection pipe 62 and the intake main pipe 51 are flexibly communicated through the corrugated expansion pipe A 621. The end of the intake connection pipe 62 away from the corrugated expansion pipe A 621 is closed. A corrugated expansion pipe B 631 is fixedly communicated between the mutually approaching ends of the exhaust connection pipe 63 and the exhaust main pipe 52. The exhaust connection pipe 63 and the exhaust main pipe 52 are flexibly communicated through the corrugated expansion pipe B 631. The end of the exhaust connection pipe 63 away from the corrugated expansion pipe B 631 is closed.

[0037] As Figure 1 , Figures 6 - 8 shown in the figure, a door pipe A 23, a door pipe B 24, a box pipe A 25 and a box pipe B 26 are fixedly arranged on the upper wall of the horizontal partition plate 2. The ends of the door pipe A 23, the door pipe B 24, the box pipe A 25 and the box pipe B 26 close to the gas distribution strip 7 are sequentially connected to the side wall of the gas distribution strip 7 and respectively penetrate the upper wall of the gas distribution strip 7.

[0038] As Figures 1 - 3 and Figures 7 - 8As shown in the figure, the push-type screen door 11 includes a fixed side door 111, a closing edge air strip 112, and a hollow door body 113. The fixed side door 111 is fixedly arranged on the front wall of the isolation box 1 and is fixedly connected to one side wall of the isolation box 1. The closing edge air strip 112 is fixedly arranged on the other side wall of the isolation box 1. The fixed side door 111 is hollow, and the closing edge air strip 112 is also hollow. The hollow door body 113 is slidably arranged on the inner wall of the hollow chamber of the fixed side door 111. The sides of the hollow door body 113 and the closing edge air strip 112 facing each other are correspondingly arranged. When the hollow door body 113 slides to the position of the closing edge air strip 112, the side edge of the hollow door body 113 is inserted into the closing edge air strip 112 and is hermetically clamped with the closing edge air strip 112. When the hollow door body 113 slides into the fixed side door 111, the isolation box 1 is in an open state, and the hollow chambers of the parts of the hollow door body 113 and the closing edge air strip 112 facing each other correspond. The door tube A 23 penetrates through the horizontal partition 2 and is laid along one side wall of the isolation box 1. The end of the door tube A 23 far from the gas distribution strip 7 is connected to the hollow chamber of the fixed side door 111 in a through manner. The door tube B 24 penetrates through the horizontal partition 2 and is laid along the other side wall of the isolation box 1. The end of the door tube B 24 far from the gas distribution strip 7 is connected to the hollow chamber of the closing edge air strip 112 in a through manner. The end of the box tube A 25 far from the gas distribution strip 7 is connected to the hollow chamber inside one side wall of the isolation box 1 in a through manner. The end of the box tube B 26 far from the gas distribution strip 7 is connected to the hollow chamber inside the other side wall of the isolation box 1 in a through manner.

[0039] As Figures 1 - 8 As shown in the figure, a pressure strip 1131 is fixedly arranged along the side wall of the hollow door body 113. The pressure strip 1131 corresponds to the gas distribution slide bar 61, and the gas distribution slide bar 61 is located on the movement path of the end of the pressure strip 1131. When the edge of the hollow door body 113 slides into the closing edge air strip 112, the pressure strip 1131 squeezes and pushes the gas distribution slide bar 61 and compresses the spring 617, so that the thin tube A 611 is correspondingly connected to the door tube A 23, the thin tube B 612 is correspondingly connected to the door tube B 24, the thick tube A 613 is correspondingly connected to the box tube A 25, the thick tube B 614 is correspondingly connected to the box tube B 26, and the ends of the thin tube C 615 and the thin tube D 616 are blocked by the upper wall of the gas distribution strip 7.

[0040] When the hollow door body 113 slides into the fixed side door 111, the pressure strip 1131 leaves the gas distribution slide bar 61. The gas distribution slide bar 61 slides under the thrust of the spring 617, and the ends of the thin tube A 611 and the thin tube B 612 are blocked by the upper wall of the gas distribution strip 7, and the thick tube A 613 is correspondingly connected to the door tube A 23, the thick tube B 614 is correspondingly connected to the door tube B 24, the thin tube C 615 is correspondingly connected to the box tube A 25, and the thin tube D 616 is correspondingly connected to the box tube B 26.

[0041] As Figures 1 - 9As shown, in this embodiment, the ventilation and filtration system 5 further includes an intake filtration valve 55, an exhaust filtration valve 56, and a spiral filtration insert 57. The intake filtration valve 55 and the exhaust filtration valve 56 are respectively fixed on the inner sidewall of the isolation box 1. The intake pump 53 and the intake filtration valve 55 are respectively connected to the middle of the intake main pipe 51, and the exhaust pump 54 and the exhaust filtration valve 56 are respectively connected to the middle of the exhaust main pipe 52. The spiral filtration insert 57 is disposed through the sidewall of the isolation box 1. The spiral filtration insert 57 is detachably inserted into the support A 21. The intake main pipe 51 and the exhaust main pipe 52 are respectively detachably connected to the spiral filtration insert 57. The spiral filtration insert 57 changes the gas flow path into a spiral shape, so that impurities such as aerosol particles in the gas can impact the inner wall of the spiral filtration insert 57, and the adsorption and purification of the gas can be realized. The intake filtration valve 55 and the exhaust filtration valve 56 respectively filter and collect large particle impurities and animal hairs in the intake main pipe 51 and the exhaust main pipe 52. The spiral filtration insert 57 includes an insertion cylinder 571, an intake spiral pipe 572, and an exhaust spiral pipe 573. The insertion cylinder 571 movably passes through the sidewall of the isolation box 1. The intake spiral pipe 572 and the exhaust spiral pipe 573 are fixedly disposed through the insertion cylinder 571. One end of the intake spiral pipe 572 and the exhaust spiral pipe 573 close to the support A 21 is fixedly connected with an insertion plate, and the insertion plate is detachably inserted into the support A 21. The intake spiral pipe 572 is connected to the intake main pipe 51 in a clamping manner, and the exhaust spiral pipe 573 is connected to the exhaust main pipe 52 in a clamping manner. Activated carbon adsorption cotton is fixedly laid on the inner walls of the intake spiral pipe 572 and the exhaust spiral pipe 573. The intake spiral pipe 572 and the exhaust spiral pipe 573 change the gas flow path into a spiral shape, so that impurities such as aerosol particles in the gas can continuously impact the activated carbon adsorption cotton, and the adsorption and purification of the gas can be realized.The intake filter valve 55 includes a filter cartridge 5511 and an accumulation cover 5512. The filter cartridge 5511 is fixedly arranged on the inner side wall of the isolation box 1, and the filter cartridge 5511 penetrates through the side wall of the isolation box 1. The accumulation cover 5512 is detachably clamped at one end of the filter cartridge 5511. The accumulation cover 5512 is located on the outer wall of the isolation box 1. The opposite ends of the filter cartridge 5511 and the accumulation cover 5512 are both closed ends, and the connected ends of the filter cartridge 5511 and the accumulation cover 5512 are both open ends. A combing shaft 5513 is rotatably arranged inside the filter cartridge 5511. One end of the combing shaft 5513 is fixedly sleeved with an impeller 5514. A spiral scraper 5515 is fixedly wound around the circumferential outer wall of the combing shaft 5513. A spiral scraping strip 5516 is fixedly arranged on the outer edge of the spiral scraper 5515. The spiral scraping strip 5516 spirally extends to the outer edge of the impeller 5514. The spiral scraping strip 5516 is in movable contact with the inner circumferential wall of the filter cartridge 5511 for scraping impurities inside the filter cartridge 5511. The intake main pipe 51 is communicated with the circumferential wall of the filter cartridge 5511. The intake main pipe 51 is partitioned into a pre-filter pipe and a post-filter pipe by the filter cartridge 5511. The pre-filter pipe and the post-filter pipe are both arranged corresponding to the impeller 5514. Gas enters the filter cartridge 5511 through the pre-filter pipe and then is discharged from the filter cartridge 5511 to the post-filter pipe. The pre-filter pipe is hollow. A filter screen 5517 is fixedly arranged at the connection part of the post-filter pipe and the filter cartridge 5511. The structure of the exhaust filter valve 56 is the same as that of the intake filter valve 55.;

[0042] In the specific use of this embodiment, the animal is placed in the receiving cavity 4, and the power cavity 3 is used to provide ventilation air flow and adjust the ventilation mode. The intake pump 53 and the exhaust pump 54 are continuously in an operating state.

[0043] The process of placing the animal into the receiving cavity 4 is as follows:

[0044] The operator horizontally pushes to open the hollow door body 113. The hollow door body 113 slides into the fixed side door 111. The pressure strip 1131 leaves the air distribution slide bar 61. The air distribution slide bar 61 slides under the thrust of the spring 617. The air distribution slide bar 61 drives the intake connection pipe 62 and the exhaust connection pipe 63 to move. The corrugated expansion pipe A 621 is compressed, and the ends of the thin pipe A 611 and the thin pipe B 612 are blocked by the upper wall of the gas distribution strip 7. And the thick pipe A 613 is correspondingly communicated with the door pipe A 23, the thick pipe B 614 is correspondingly communicated with the door pipe B 24, the thin pipe C 615 is correspondingly communicated with the box pipe A 25, and the thin pipe D 616 is correspondingly communicated with the box pipe B 26. At this time, the gas path in the equipment is as Figure 7As shown, the intake pump 53 transports outside air through the intake manifold 572 to the intake main pipe 51. After being filtered by the intake filter valve 55, the air continues to be transported along the intake main pipe 51, through the corrugated expansion pipe A 621 to the intake manifold 62. At this time, the thin pipe A 611 is blocked and there is no air flow. One branch of the air flow is transported through the thick pipe B 614 to the door pipe B 24 and blown out from the edge wind strip 112. The other branch of the air flow is transported through the thin pipe C 615 to the box pipe A 25 and blown out from the ventilation hole 12 on one side wall of the isolation box 1.

[0045] Meanwhile, the exhaust pump 54 also drives the gas flow. The exhaust pump 54 extracts the gas in the exhaust main pipe 52 and the exhaust manifold 63. A negative pressure is formed in the exhaust manifold 63. Since the end of the thin pipe B 612 is blocked by the upper wall of the gas distribution strip 7 at this time, the thick pipe A 613 and the thin pipe D 616 will respectively form air flows and enter the exhaust manifold 63. In terms of the thick pipe A 613, the gas outside the hollow door body 113 is sucked into the hollow door body 113 and enters the thick pipe A 613 through the fixed edge door 111 and the door pipe A 23. A directional air flow curtain to the left (taking Figure 7 as an example) is formed between the hollow door body 113 and the edge wind strip 112, so that the push - type shielding door 11 realizes the air flow curtain shielding effect, effectively preventing the gas interaction between the inside and outside of the isolation box 1. In terms of the thin pipe D 616, the gas outside the other side wall of the isolation box 1 is sucked in through the ventilation hole 12 on it and enters the thin pipe D 616 through the box pipe B 26. A directional air flow to the right (taking Figure 7 as an example) is formed between the two side walls of the isolation box 1 (i.e., the accommodation cavity 4), so as to realize the ventilation of the inside of the accommodation cavity 4. And at this time, the push - type shielding door 11 is in the open state, and the air flows in the thick pipe A 613 and the thick pipe B 614 are larger, that is, the air flow volume between the edge wind strip 112 and the hollow door body 113 is larger, thus ensuring the intensity of the air flow curtain at this place and improving the shielding effect.

[0046] After the animal enters the accommodation cavity 4, the operator pulls the hollow door body 113, making the hollow door body 113 slide towards the edge wind strip 112. The side of the hollow door body 113 is inserted into the edge wind strip 112 and is hermetically clamped with the edge wind strip 112. The pressure strip 1131 squeezes and pushes the air - dividing slide bar 61 and compresses the spring 617, so that the thin pipe A 611 is correspondingly communicated with the door pipe A 23, the thin pipe B 612 is correspondingly communicated with the door pipe B 24, the thick pipe A 613 is correspondingly communicated with the box pipe A 25, and the thick pipe B 614 is correspondingly communicated with the box pipe B 26. The ends of the thin pipe C 615 and the thin pipe D 616 are blocked by the upper wall of the gas distribution strip 7. The gas path in the equipment is as Figure 8As shown, the intake pump 53 conveys external air to the intake main pipe 51 and the intake manifold 62. One branch of the air flow is conveyed from the thin pipe A 611 to the door pipe A 23 and blown out through the fixed side door 111 and the hollow door body 113. The other branch of the air flow is conveyed from the thick pipe B 614 to the box pipe B 26 and blown out through the ventilation holes 12 on the other side wall of the isolation box 1;

[0047] Meanwhile, the exhaust pump 54 extracts the gas in the exhaust main pipe 52 and the exhaust manifold 63. The thin pipe B 612 and the thick pipe A 613 will respectively form air flows and enter the exhaust manifold 63. In terms of the thin pipe B 612, the gas blown out from the hollow door body 113 enters the thin pipe B 612 through the edge wind strip 112 and the door pipe B 24. In terms of the thick pipe A 613, the gas outside one side wall of the isolation box 1 is inhaled through the ventilation holes 12 thereon and enters the thick pipe A 613 through the box pipe A 25. A directional air flow to the left (taking Figure 8 as an example) is formed between the two side walls in the isolation box 1 (i.e., the accommodation cavity 4), so as to realize the reverse ventilation inside the accommodation cavity 4. At this time, the push-type shielding door 11 is in the closed state. The air flows in the thin pipe A 611 and the thin pipe B 612 corresponding to the edge wind strip 112 and the hollow door body 113 are smaller, while the air flows in the thick pipe A 613 and the thick pipe B 614 are larger, that is, the air flows in the box pipe A 25 and the box pipe B 26 are larger, and the air flow effect can be more fully utilized to realize ventilation.

[0048] During the whole using process, the intake spiral pipe 572 and the exhaust spiral pipe 573 in the spiral filter plug-in 57 change the gas flow paths in the intake main pipe 51 and the exhaust main pipe 52 into spiral shapes, so that aerosol particles and other impurities in the gas can impact on the inner walls of the intake spiral pipe 572 and the exhaust spiral pipe 573, and the adsorption and purification of the gas can be realized.

[0049] The intake filter valve 55 and the exhaust filter valve 56 respectively filter and collect large particle impurities and animal hairs in the intake main pipe 51 and the exhaust main pipe 52. When the gas flows through the intake filter valve 55, it blows the impeller 5514, so that the combing shaft 5513 rotates. The animal hairs and large particle impurities in the gas move with the air flow and are blocked by the filter screen 5517. The combing shaft 5513 drives the spiral scraping strip 5516 to rotate, and the spiral scraping strip 5516 scrapes the inner wall of the filter cylinder 5511, so as to gradually scrape the animal hairs and large particle impurities on the filter screen 5517 into the accumulation cover 5512. The principle in the exhaust filter valve 56 is the same and will not be elaborated. The operator only needs to regularly pull out the accumulation cover 5512 to clean the intake filter valve 55 and the exhaust filter valve 56.

[0050] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the structures of the intake filter valve 55 and the exhaust filter valve 56 in this embodiment are different from those in Embodiment 1, such as Figure 5 andFigure 10 As shown, in this embodiment, the intake air filter valve 55 includes a filter box 5521 and a plug cover 5522. The filter box 5521 is fixedly arranged on the inner side wall of the isolation box 1, and the plug cover 5522 is detachably clamped at one end of the filter box 5521. The plug cover 5522 is located on the outer wall of the isolation box 1. A filter plate 5523 is fixedly arranged on one side of the plug cover 5522. The filter plate 5523 is located inside the filter box 5521, and the filter plate 5523 is in sliding fit with the inner wall of the filter box 5521. The intake main pipe 51 is connected to the side wall of the filter box 5521 in a penetrating manner. The intake main pipe 51 is blocked by the filter box 5521. The filter plate 5523 is located between the two connection ports of the intake main pipe 51 and the filter box 5521, and is used to block impurities in the filtered gas. The structure of the exhaust air filter valve 56 is the same as that of the intake air filter valve 55.

[0051] When this embodiment is specifically used, the overall method is the same as that of the first embodiment, and the only difference lies in the different filtering principles of the intake air filter valve 55 and the exhaust air filter valve 56. In this embodiment, animal hairs and large-particle impurities are directly blocked by the filter plate 5523. During cleaning, the filter plate 5523 can be pulled out together with the plug cover 5522, thereby realizing cleaning.

[0052] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto.
