It has a simple structure, good adjustability, strong versatility, convenient use, good effect, comfortable wearing and reliable.

[0004] In the prior art, in order to keep patients safe in the ward and reduce cross-infection among patients, patients and other personnel need to wear masks for protection. However, for patients in the respiratory department who have breathing difficulties, coughs, and sputum, masks can cause a lot of discomfort and inconvenience.

[0005] To this end, the present invention provides a portable air filter for respiratory care. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the portable air filter for respiratory care described in the present invention comprises a filter body and a mask; a support plate is fixedly connected to the inside of the filter body; a motor is fixedly connected to the bottom surface of the support plate; a rotating column is rotatably connected to the top of the support plate, and the rotating column is fixedly connected to the output shaft of the motor; a fan blade is fixedly connected to the surface of the rotating column near the top surface of the rotating column; an air inlet is opened on the top of the filter body; a filter plate is fixedly connected to the inside of the air inlet; a connecting tube is fixedly connected to the side of the filter body near the bottom of the filter body; a mask is connected to the end of the connecting tube away from the filter body; during work, in order to maintain the safety of patients in the ward and reduce the problem of cross infection among patients, patients and other personnel need to wear masks for protection, but for patients in the respiratory department, such as Masks can cause a lot of discomfort and inconvenience for patients with breathing difficulties, coughing, and expectoration. First, the patient puts on the mask and connects the mask to the filter body through a connecting tube. By starting the motor, the rotation of the motor will drive the rotating column to rotate, and the rotating column will drive the fan blade to rotate. Through the rotation of the fan blade, external air will be sucked into the interior of the air filter, filtered through the filter plate of the air filter, so that the filtered air is introduced into the connecting tube, and then introduced into the interior of the mask through the connecting tube. Through the action of the fan blade, clean gas is supplied to the interior of the mask in time, reducing the problem of cross infection inside the respiratory department, and at the same time improving the comfort of wearing the mask, reducing the stuffiness of patients wearing masks, especially for patients with breathing difficulties. The action of the fan blade can promote the flow of air inside the mask. At the same time, the filter body is small in size and can be held directly by the patient, which is highly portable.

At the same time, when the disinfection box 19 is completely introduced into the interior of the first slide groove, the protruding structure at the bottom of the first slide groove will be directly inserted into the interior of the elastic hole to open the elastic hole, and then the inlet hole 20 is in an automatically opened state, ensuring that the disinfection box 19 and the interior of the connecting hole 26 are normally connected.

[0037] Embodiment 2

[0038] like Figure 5As shown, compared with Example 1, another implementation of the present invention is: the sealing block 27 is located on the side wall of the disinfection box 19 near the top surface of the disinfection box 19; during operation, in order to avoid the disinfectant water being directly introduced into the elastic hole of the sealing block 27, and then directly flowing into the connecting hole 26 through the elastic hole, causing the mask 2 to be directly immersed in the disinfectant water, affecting the normal use of the mask 2 in the later stage, the sealing block 27 is placed near the top position of the disinfection box 19 to ensure the normal disinfection.

[0039] The interior of the disinfection box 19 is fixedly connected with absorbent cotton 28 between the inlet hole 20 and the outlet hole 21. During operation, the absorbent cotton 28 is arranged inside the disinfection box 19, so that part of the disinfectant water inside the disinfection box 19 can be sucked in through the absorbent cotton 28. When the air inside the disinfection box 19 flows, the contact area between the absorbent cotton 28 and the air is larger, which is more conducive to the gasification or volatilization of the disinfectant water, so that the amount of disinfectant water vapor carried in the air is sufficient to meet the disinfection demand, thereby improving the disinfection effect on the inside of the holding cup 16. At the same time, when the mask 2 is placed in the holding box 24, the mask 2 can also be fully disinfected.

[0040] During operation, the patient first wears the mask 2, and connects the mask 2 to the filter body 1 through the connecting tube 9, and starts the motor 4.

The rotation of the fan blade 6 draws the external air into the interior of the air filter, and is filtered through the filter plate 8 of the air filter, so that the filtered air is introduced into the connecting tube 9, and then introduced into the interior of the mask 2 through the connecting tube 9. Through the action of the fan blade 6, the interior of the mask 2 is supplied with clean gas in time, thereby reducing the problem of cross infection in the respiratory department, and at the same time improving the wearing comfort of the mask 2 and reducing the patient's wearing The stuffy feeling of wearing the mask 2, especially for patients with breathing difficulties, can be promoted to flow the air inside the mask 2 through the action of the fan blades 6. At the same time, the filter body 1 is small in size and can be directly held by the patient, which is highly portable. By arranging the telescopic block 12 inside the mask 2, when the patient needs to spit, the patient manually pulls up the guide block 11, the guide block 11 slides inside the guide groove and drives the connecting rope 13, the connecting rope 13 pulls the telescopic block 12, so that the telescopic block 12 contracts, and the guide hole 10 at the bottom of the mask 2 opens, and the patient can directly spit at the designated trash can position through the guide hole 10, without having to repeatedly take off the mask 2, which is more convenient to use. The invention is more convenient. After spitting, the elastic force of the elastic rope 14 will drive the telescopic block 12 to reset and automatically block the guide hole 10. By arranging the holding cup 16 at the bottom of the mask 2, the patient can directly spit the sputum into the holding cup 16 when spitting. During the spitting process, the patient will not inhale the unfiltered air from the outside, and the exhaled gas will not be directly discharged without filtering, which ensures the health and safety of the patient and others, reduces the spread of bacteria and viruses, and at the same time, the spitted sputum will not be directly exposed to the air, and it is more convenient for the patient to spit. After spitting, the telescopic block 12 can also serve as a barrier. After use, the holding cup 16 can be directly replaced; under winter environmental conditions, for respiratory patients, cold air will exacerbate the condition. By arranging a heating wire 18 inside the filter body 1, the heating wire 18 can heat the air, so that the patient can inhale warm air under winter conditions to relieve the patient's condition; by designing the filter body 1 near the heating wire 18 as a heat-conducting material, when the filter body 1 works in winter, the heating wire 18 is heated, and the heating wire 18 will also heat the heat-conducting material of the filter body 1, and the patient can hold the filter body 1 to warm the chest or hands;By arranging a disinfection box 19 on one side of the filter body 1, when the gas inside the filter body 1 is discharged, the gas will first be introduced into the disinfection box 19 through the inlet hole 20, and the gas will vaporize part of the disinfection water inside the disinfection box 19 and carry it out together, and then be introduced into the interior of the holding cup 16 through the outlet hole 21 and the second connecting pipe 23, so as to continuously disinfect the interior of the holding cup 16, and other gases inside the filter body 1 will be introduced into the interior of the mask 2 through the first connecting pipe 22, and the gas introduced into the interior of the mask 2 does not carry the gas generated by the disinfection water, so as to ensure that the wearer inhales fresh air; since the cost of this type of mask 2 is relatively high, in order to save expenses, the mask 2 is used After using it for a period of time, directly pull out the containing box 24 inside the second slide slot, then pull out the mask 2 from between the first connecting tube 22, and at the same time pull out the containing cup 16 from between the second connecting tube 23, take out the containing cup 16 from the bottom of the mask 2, and then place the mask 2 directly inside the containing box 24, and start the motor 4 to rotate in the reverse direction, the motor 4 will drive the fan blade 6 to rotate, the fan blade 6 will make the gas pass through the first connecting tube 22 and the second connecting tube 23 to be respectively introduced into the connecting hole 26 and the outlet hole 21, and the gas is reversely introduced into the disinfection box 19 through the outlet hole 21, and then the gas carrying the disinfection gas is reversely introduced into the connecting hole 26 through the inlet hole 20, and finally the gas is in the connecting hole 26. The inside of the hole 26 is collected and introduced into the holding box 24 through the bottom hole 25, and then introduced into the inside of the filter body 1 through the holding box 24, and then the gas is discharged in the reverse direction through the filter body 1. Since the air carries the disinfecting gas, it will be introduced into the holding box 24, and the disinfecting gas will continuously disinfect the surface of the mask 2, and then the motor 4 will be rotated in the forward direction to heat and disinfect the mask 2, so as to achieve full disinfection of the mask 2, facilitate the secondary use of the mask 2, and reduce the cost of use; by arranging a sealing block 27 at the position of the inlet hole 20, the sealing block 27 is elastically designed, and then the elastic hole is in a sealed state in the initial state, and the inside of the disinfection box 19 is filled and disinfected When water is passed through the sealing block 27, the disinfectant water can be reduced from being directly discharged from the elastic hole. At the same time, when the disinfection box 19 is completely introduced into the first chute, the protruding structure at the bottom of the first chute will be directly inserted into the elastic hole to open the elastic hole, and then the inlet hole 20 is in an automatically opened state, ensuring that the disinfection box 19 and the connecting hole 26 are normally connected. In order to avoid the problem that the disinfectant water is directly introduced into the elastic hole of the sealing block 27, and then directly flows into the connecting hole 26 through the elastic hole, causing the mask 2 to be directly immersed in the disinfectant water, affecting the normal use of the mask 2 in the later stage, the sealing block 27 is placed close to the top of the disinfection box 19 to ensure the normal disinfection.By arranging absorbent cotton 28 inside the disinfection box 19, the absorbent cotton 28 can partially absorb the disinfectant water inside the disinfection box 19. When the air inside the disinfection box 19 flows, the contact area between the absorbent cotton 28 and the air is larger, which is more conducive to the gasification or volatilization of the disinfectant water, so that the amount of disinfectant water vapor carried in the air is sufficient to meet the disinfection requirements, improve the disinfection effect of the inside of the holding cup 16, and at the same time, when the mask 2 is placed in the holding box 24, it can also meet the full disinfection of the mask 2. ;
