[0002] As an effective means of artificially replacing spontaneous ventilation, ventilators are widely used in respiratory failure caused by various reasons, anesthetic respiratory management during major surgery, respiratory support therapy, and emergency resuscitation, occupying a very important position in the field of modern medicine. A ventilator is a crucial medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. Currently, some ventilators require drawing in outside air as an oxygen source. However, outside oxygen contains impurities, such as lint and dust from indoor environments. Ventilators typically use filter bags to filter the oxygen, but after a period of use, a large amount of impurities remain on the surface of the filter bags. If these impurities are not treated in time, they can easily become moldy, leading to an unpleasant odor or even bacteria in the oxygen provided by the ventilator. Summary of the Invention

[0014] The present invention has the following beneficial effects: When the ventilator is needed, the operator opens the sealed door, and the ventilator can begin operation. After connecting the pipe to the surface of the connecting tube, oxygen from the ventilator enters the pipe for oxygen supply. During operation, oxygen enters the ventilator through the filter frame. As the oxygen flows through the filter frame, the perforated plate processes the oxygen, preventing impurities such as lint from entering. After the perforated plate completes filtration, the filter plate filters the oxygen again to prevent impurities from affecting its quality. When the oxygen from the filter frame enters the ventilator, the filter bag filters out small particles again, further filtering dust and improving the oxygen treatment effect, thus preventing dust from affecting its quality.
[0015] When the power unit of this invention starts operation, it drives the threaded rod to rotate. The rotation of the threaded rod, via a pulley and belt, drives the screw to rotate. This rotation pushes the screw hole frame to move. The screw hole frame, in turn, moves the scraper via a sliding rod. The scraper cleans the surface of the filter plate, preventing impurities from accumulating and affecting its air intake performance. Simultaneously, the rotation of the threaded rod pushes the anti-stacking plate to move. This anti-stacking plate cleans the surface of the inclined plate, preventing dust accumulation and facilitating thorough cleaning. The anti-stacking plate is also moved via a spring rod. The cleaning frame moves, cleaning the lower surface of the filter bags to prevent oxygen particles from accumulating and clogging them, thus improving oxygen filtration efficiency. It also prevents the filter bags and filter plates from being blocked, which would affect air intake. Keeping the filter bags and filter plates clear also improves the ventilator's heat dissipation, preventing heat from being trapped by dust. The cleaning frame also pushes the rollers at the bottom of the clamping plate, improving the stability of the filter bags during cleaning and preventing the cleaning frame from tilting.
[0016] This invention uses an atomizing nozzle to humidify oxygen, preventing dryness that could cause discomfort to the user. Humidification also cools the inside of the ventilator, preventing overheating. A one-way valve is installed on the top of the mounting frame. When the one-way valve is opened, any accumulated liquid on the top of the mounting frame flows through the valve into the collection component and is discharged, preventing liquid buildup inside the ventilator.
[0017] When the sealed door is closed, gas enters the dust collection bag and is discharged. At this time, the dust in the gas is intercepted and stored by the dust collection bag. The magnetic suction plate is magnetically connected to the bottom of the filter frame, which makes it easy to disassemble the dust collection bag to process the dust inside. After cleaning, the anti-stacking plate separates from the squeezing plate. The squeezing plate is reset by the spring sheet. At this time, the opening and closing plate will be closed by the elastic reset of the elastic sheet. The moving plate is closed by the elastic sheet to prevent the dust in the dust collection bag from floating out during the operation of the ventilator.
[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Please see Figures 1-15 As shown, the present invention is a high-efficiency filtration and heat dissipation device for a medical ventilator, including a filter frame 1, a ventilator 2 fixedly connected to the top of the filter frame 1, and a filter component 8 disposed inside the filter frame 1.

A filter plate 22 is provided on the surface of the baffle 27. A perforated plate 24 is slidably connected to the inner wall of the filter frame 1. A sealing door 23 is hinged to the lower surface of the filter frame 1. When the ventilator 2 needs to be used, the operator... The operator opens the sealed door 23, and the ventilator 2 can then begin operation. At this time, after the operator connects the pipe to the surface of the connecting pipe 4, the oxygen in the ventilator 2 will enter the pipe through the connecting pipe 4 for oxygen supply. When the ventilator 2 is in operation, the oxygen will enter the interior of the ventilator 2 through the filter frame 1. When the oxygen flows inside the filter frame 1, the sieve plate 24 will process the oxygen entering the interior of the filter frame 1 to prevent impurities such as cotton wool from entering the interior of the filter frame 1. After the sieve plate 24 completes the filtration of the oxygen, the filter plate 22 will filter the oxygen again to prevent the oxygen from containing impurities and causing poor quality. When the oxygen in the filter frame 1 enters the interior of the ventilator 2, the filter bag 25 will filter the small particles in the oxygen again. The filter bag 25 will filter the dust in the oxygen again to improve the oxygen treatment effect and prevent the oxygen from containing dust and causing poor quality. The filter frame 1 is equipped with an anti-clogging component 9, the ventilator 2 is equipped with a humidifying component 10, and the bottom of the filter frame 1 is equipped with a collecting component 11.

[0025] The top of the tripod 21 has a through hole. The surface of the mounting frame 20 is fixedly connected to the inner wall of the ventilator 2. The end of the filter bag 25 is located at the end of the side plate 26 and the through plate 29 that are close to each other. There are two clamping plates 28, which are symmetrically arranged with the filter bag 25 as the center. The surface of the clamping plate 28 is in contact with the inner wall of the slot 30.

The surface of the filter plate 22 is in contact with the inner wall of the filter frame 1. The top of the perforated plate 24 penetrates the filter frame 1 and extends to the top outer end of the filter frame 1. The bottom of the perforated plate 24 is slidably connected to the inner wall of the filter frame 1.
[0026] The anti-clogging component 9 includes a threaded rod 42, the end of which is rotatably connected to the inner wall of the filter frame 1. A screw 43 is rotatably connected to the inner wall of the filter frame 1. An anti-stacking plate 51 is threadedly connected to the surface of the threaded rod 42. A spring rod 52 is fixedly connected to the surface of the anti-stacking plate 51. A cleaning frame 53 is fixedly connected to the top of the spring rod 52. A ball bearing 54 is rotatably connected to the inner wall of the top of the cleaning frame 53. A sliding plate 50 is fixedly connected to the surface of the anti-stacking plate 51. An inclined plate 40 is fixedly connected to the top of the inner wall of the filter frame 1. A groove 41 is formed on the upper surface of the inclined plate 40.

Pulleys 49 are fixedly connected to the surfaces of the threaded rod 42 and the screw 43, respectively. A belt 48 is driven through the inner walls of the two pulleys 49. During operation, the power unit 5 drives the threaded rod 42 to rotate. When the threaded rod 42 rotates, it drives the screw 43 to rotate via the pulleys 49 and the belt 48. The rotation of the threaded rod 42 pushes the screw hole frame 44 to move. During movement, the slide bar 45 drives the scraper 47 to move, cleaning the surface of the filter plate 22 to prevent impurities from accumulating and affecting its air intake performance. Meanwhile, the threaded rod 42, when rotating, pushes the anti-stacking plate 51 to move, cleaning the surface of the inclined plate 40 to prevent dust accumulation and ensure effective cleaning. The anti-stacking plate 51, when moving, pushes the cleaning frame 53 via the spring rod 52, cleaning the lower surface of the filter bag 25 to prevent particles in the oxygen from accumulating. Particles accumulate on the surface of the filter bag 25, causing it to become clogged. This improves the filtration effect on oxygen and prevents the filter bag 25 and filter plate 22 from being blocked, thus affecting the air intake effect. At the same time, keeping the filter bag 25 and filter plate 22 unobstructed will improve the heat dissipation effect of the ventilator 2, preventing the heat in the ventilator 2 from being blocked by dust and unable to dissipate, thereby improving the heat dissipation effect of the ventilator 2. When the cleaning frame 53 moves, it pushes the ball 54 to move at the bottom of the clamping plate 28, improving the stability of the filter bag 25 during the cleaning operation and preventing the cleaning frame 53 from tilting during the cleaning operation.
[0027] The screw 43 is located at one end of the filter plate 22 and the screen plate 24 that are close to each other.

An air pump 68 is installed on the top of the filter frame 1. The air outlet of the air pump 68 is connected to a bend pipe 64. The lower surface of 68 is connected to an air inlet pipe 63. The end of the air inlet pipe 63 away from the air pump 68 passes through the ventilator 2 and is connected to the top of the sealing plate 60. The oxygen is humidified through the nebulizer nozzle 69 to prevent the oxygen from being too dry and causing discomfort to the user. At the same time, the oxygen humidification will also cool down the inside of the ventilator 2 to prevent the ventilator 2 from overheating. The top of the mounting frame 20 is equipped with a one-way valve. When the one-way valve is opened, the liquid accumulated on the top of the mounting frame 20 will flow through the one-way valve into the collection component 11 for discharge, preventing the liquid from accumulating inside the ventilator 2.
[0030] There are two sealing plates 61, which are symmetrically arranged with the tripod 21 as the center. The end of the shunt tube 65 passes through the ventilator 2 and extends into the interior of the ventilator 2.

A hinged elastic sheet 79 is connected to the filter frame 1. The end of the elastic sheet 79 away from the round rod 78 is fixedly connected to the inner wall of the filter frame 1. When the sealing door 23 is closed, the gas will enter the interior of the dust collection bag 73 and be discharged. At this time, the dust in the gas will be intercepted and stored by the dust collection bag 73. The magnetic suction plate 75 is magnetically connected to the bottom of the filter frame 1, which makes it easy to disassemble the dust collection bag 73 to process the dust inside. After cleaning, the anti-stacking plate 51 separates from the squeezing plate 70. The squeezing plate 70 is reset by the spring piece 71. At this time, the opening and closing plate 74 will be closed by the elastic reset of the elastic piece 72. The moving plate 77 is closed by the elastic closing of the elastic piece 79 to prevent the dust in the dust collection bag 73 from floating out under the operation of the ventilator 2.
[0032] The extrusion plate 70 is inclined, and there are two opening and closing plates 74. The two opening and closing plates 74 are symmetrically arranged with the extrusion plate 70 as the center, and the lower surface of the extrusion plate 70 is in contact with the surface of the opening and closing plate 74. There are two magnetic suction plates 75. The two magnetic suction plates 75 are located below the opening and closing plate 74 and the moving plate 77, respectively. The end of the round rod 78 away from the moving plate 77 passes through the filter frame 1 and is in contact with the surface of the opening and closing plate 74.
[0033] When using ventilator 2, the operator opens the sealing door 23, and ventilator 2 can begin operation. After connecting the pipe to the surface of the connecting pipe 4, oxygen from ventilator 2 enters the pipe through the connecting pipe 4 for oxygen supply. During operation, oxygen enters ventilator 2 through filter frame 1. As the oxygen flows through filter frame 1, the perforated plate 24 processes the oxygen entering the filter frame 1, preventing impurities such as lint from entering. After the perforated plate 24 completes filtration, the filter plate 22 filters the oxygen again to prevent impurities from affecting its quality. When oxygen from filter frame 1 enters ventilator 2, the filter bag 25 filters out small particles and dust particles again. To improve the oxygen treatment effect and avoid poor quality due to dust in the oxygen, when the filter plate 22 needs to be cleaned and replaced, push the perforated plate 24 to move to the top outer end of the filter frame 1. At this time, the filter plate 22 can be pulled out to the outer end of the filter frame 1 to complete its disassembly. After the filter plate 22 is disassembled, the operator can put his hand into the inside of the filter frame 1 and contact the side plate 26. At this time, pull the side plate 26 downward to remove the filter bag 25 from the inside of the ventilator 2. When replacing it, remove the perforated plate 29 from the surface of the side plate 26 to replace the filter bag 25. After the replacement is completed, fix the filter bag 25 to the surface of the side plate 26 through the perforated plate 29. When the side plate 26 is placed into the inside of the ventilator 2, the side plate 26 can fix the filter bag 25 inside the tripod 21 through the magnetic connection with the tripod 21, improving the convenience of replacing the filter plate 22 and the filter bag 25. When the power unit 5 is started, it drives the threaded rod 42 to rotate. The rotation of the threaded rod 42, via the pulley 49 and belt 48, drives the screw 43 to rotate. The rotation of the threaded rod 42 pushes the screw hole bracket 44 to move. The movement of the screw hole bracket 44, via the sliding rod 45, drives the scraper 47 to move. The scraper 47 cleans the surface of the filter plate 22, preventing impurities from accumulating on the surface and affecting the air intake effect of the filter plate 22. Meanwhile, the rotation of the threaded rod 42 pushes the anti-stacking plate 51 to move. The anti-stacking plate 51 cleans the surface of the inclined plate 40, preventing dust accumulation on the surface of the inclined plate 40 and affecting its concentrated cleaning. The movement of the anti-stacking plate 51 is also facilitated by the spring rod. 52 pushes the cleaning frame 53 to move. When the cleaning frame 53 moves, it cleans the lower surface of the filter bag 25 to prevent particles in the oxygen from accumulating on the surface of the filter bag 25 and causing the filter bag 25 to become blocked, thereby improving the filtration effect of oxygen. It also prevents the filter bag 25 and filter plate 22 from being blocked, which would affect the air intake effect. At the same time, keeping the filter bag 25 and filter plate 22 unobstructed will improve the heat dissipation effect of the ventilator 2, preventing the heat in the ventilator 2 from being blocked by dust and thus improving the heat dissipation effect of the ventilator 2. When the cleaning frame 53 moves, it pushes the ball 54 to move at the bottom of the clamping plate 28, which improves the stability of the filter bag 25 during the cleaning operation and prevents the cleaning frame 53 from tilting during the cleaning operation. After filtration, the oxygen enters the ventilator 2 through the tripod 21. It then passes through the ventilation valve 62 to the top of the mounting frame 20, and from there enters the connecting pipe 4 for oxygen supply. When the micro pump 67 is activated, it draws liquid from the humidification tank 66 into the distribution pipe 65, which then transmits the liquid to the nebulizer nozzle 69. The nebulizer nozzle 69 humidifies the oxygen, preventing dryness and discomfort for the user. Humidification also cools the inside of the ventilator 2, preventing overheating. A one-way valve is installed on the top of the mounting frame 20. When the one-way valve is opened, the accumulated liquid on the top of the mounting frame 20 flows into the collection component. To prevent liquid accumulation inside the ventilator 2, the air valve 62 is closed when backwashing the filter bag 25 and filter plate 22 is required. When the air pump 68 is started, it draws the filtered oxygen and transmits it to the bend tube 64. The bend tube 64 backwashes the oxygen into the tripod 21 and flows towards the outer end of the filter frame 1. At this time, the air pressure will flush the filter bag 25. The anti-stacking plate 51, cleaning frame 53 and scraper 47 will push the dust up during operation. When the gas backwashes, the gas will flow into the inside of the collection component 11. During the flow, the gas will carry the dust into the inside of the collection component 11, thereby recovering the dust in the filter frame 1 and improving the convenience of cleaning the dust inside the filter frame 1, making the ventilator 2 more convenient to use. When cleaning the dust inside the filter frame 1, the threaded rod 42 pushes the anti-stacking plate 51 under the baffle 27. The anti-stacking plate 51 then presses against the squeezing plate 70. At this time, the squeezing plate 70 rotates around the baffle 27 and presses against the opening and closing plate 74. The two opening and closing plates 74 move away from each other. As they move, the opening and closing plates 74 push the moving plate 77 into the storage tank 76 via the round rod 78. When the air pump 68 backwashes the dust inside the filter frame 1, the gas enters the dust collection bag when the sealing door 23 is closed. The dust in the gas is intercepted by the dust collection bag 73 and discharged. The magnetic suction plate 75 is magnetically connected to the bottom of the filter frame 1, which makes it easy to disassemble the dust collection bag 73 to process the dust inside. After cleaning, the anti-stacking plate 51 separates from the squeezing plate 70. The squeezing plate 70 is reset by the spring piece 71. At this time, the opening and closing plate 74 will be closed by the elastic reset of the elastic piece 72. The moving plate 77 is closed by the elastic piece 79 to prevent the dust in the dust collection bag 73 from floating out under the operation of the ventilator 2.
