Description

Technical Field

[0001] The present application relates to the technical field of environmental disinfection equipment, and in particular to an air purifier and disinfector for respiratory medicine. Background Art

[0002] In medical treatment, especially for patients with respiratory diseases, such as lung disease patients, when they are recovering, the air in the recovery environment often needs to be disinfected by atomizing disinfectant or the humidity in the ward needs to be improved. Because respiratory patients have high requirements for indoor temperature and humidity, dry air will cause sputum to be thick and difficult to cough up. Problems with air bacteria culture and environmental monitoring indicators will increase the infection rate of respiratory diseases, cross infection between patients, especially multi-drug resistant bacteria infection, which seriously affects the prognosis of patients and increases the economic burden. Therefore, air purification and disinfection are very important; When the existing air sterilizer is in use, such as a disinfectant atomizer and environmental disinfection equipment provided by publication number CN118060118A, the disinfectant atomizer includes a liquid supply module, an infusion module and a nozzle module, the nozzle module is connected to the liquid supply module through the infusion module, the nozzle module includes a nozzle body, a nozzle back cover and an atomizing nozzle hole, the nozzle body is a rectangular shell structure with an opening on the rear side, and a threaded hole is provided on the front end surface of the nozzle body; by setting a disinfectant atomizer composed of a liquid supply module, an infusion module and a nozzle module, and setting the nozzle module to be composed of a nozzle body, a nozzle back cover and The atomizing spray hole is composed of a mounting base, a spray hole head, a connecting pipe, a filter ball and a filter tube, so that impurities in the disinfectant are filtered and removed by the filter tube and the filter ball, thereby effectively preventing impurities from entering the interior of the atomizing spray hole and causing blockage, thereby effectively improving the actual service life of the nozzle module. The nozzle is fixedly installed on the atomizer so that when disinfecting, the nozzle sprays disinfectant in a certain direction. For the position in the environment opposite to the nozzle opening, the atomized liquid needs to be driven slowly to the position by the flow of air, which makes the disinfection efficiency of the device low.

[0006] Furthermore, the connecting pipe comprises a lower pipe and an upper pipe, a rotating ring is rotatably installed between the upper pipe and the lower pipe, a rotating paddle is installed on the rotating ring, and a stirring blade is installed on the rotating ring.

[0007] Furthermore, a vertical rod is installed on the propeller shaft, the vertical rod is connected to the shielding cover, the connecting rod is installed on the top of the shielding cover, and an arc block is installed on the inner wall of the shielding cover.

[0008] Furthermore, an inner channel and an outer channel are provided in the nozzle, the inner diameter of the inner channel is smaller than the inner diameter of the outer channel, a sealing plate is slidably installed in the inner channel via a connecting spring, the diameter of the sealing plate is larger than the inner diameter of the inner channel and smaller than the inner diameter of the outer channel, and bristles are installed on the side wall of the sealing plate.

[0009] Furthermore, a brush wheel is rotatably mounted on the blocking plate, a guide block is mounted on the brush wheel, and a spiral groove slidably matched with the guide block is provided in the outer channel, so that when the blocking plate slides, the brush wheel rotates in the outer channel.

[0010] Furthermore, a ring sleeve is rotatably mounted on the upper tube via a torsion spring, an arc plate is mounted on the ring sleeve, and the arc plate is used to be inserted into the mask opening, with the arc surface of the arc plate facing the rotation direction of the mask opening.

[0011] Furthermore, a centralizing pipe is installed on the shielding cover, one end of which is connected to the upper pipe, and the centralizing pipe is used to shield the gap between the upper pipe and the shielding cover.

[0012] Furthermore, the diameter of the centralizing pipe gradually decreases from the direction toward the shielding cover to the direction away from the shielding cover, and a recovery hole is opened on the upper pipe at the point where the diameter of the centralizing pipe is the smallest. A one-way valve is installed in the recovery hole, and the one-way valve allows the disinfectant to flow only from the centralizing pipe to the recovery hole.

[0013] Furthermore, a heat-conducting shell for wrapping the air pump is installed in the mounting shell, a heat-conducting tube connected to the atomizing shell is installed on the heat-conducting shell, a mounting frame is installed in the atomizing shell, the mounting frame is rotatably matched with the connecting rod, the mounting frame is tiltedly arranged in the atomizing shell, and the pipe mouth of the heat-conducting tube is located at the lowest point of the mounting frame.

[0015] The beneficial effects of this application are as follows: 1. The present application is provided with a liquid storage shell and an atomization shell connected by a connecting pipe on the mounting shell, and the air pump ejects airflow to drive the disinfectant in the liquid storage shell to move toward the shielding cover. When the high-speed airflow drives the disinfectant to collide with the shielding cover, it forms smaller water droplets and completes atomization. The atomized disinfectant moves into the rotating shell through the cover mouth. The airflow generated by the air pump also drives the rotating paddle to drive the rotating shell to rotate, so that the nozzle can rotate in the horizontal direction. During the rotation, the counterweight block and the protruding block collide or release the conflict, so that the nozzle swings in the vertical direction, which increases the mobility of the nozzle and thereby increases the disinfection efficiency of the device.

[0017] 3. In the present application, when the airflow drives the disinfectant to move into the shielding cover and collides with the shielding cover, the shielding cover drives the arc block to collide with the airflow through rotation. The arc block makes the inner wall of the shielding cover uneven, which can better collide with the airflow and disperse it, so that the atomized liquid can be dispersed into smaller liquid droplets, further increasing the effect of the device in atomizing the disinfectant.

[0018] 4. When the present application is in use, the length of the atomizing shell can be adjusted so that the kinetic energy of the atomizing airflow can be consumed as it moves in the atomizing shell, thereby further reducing the possibility that the atomizing airflow will disrupt the external environment, and the thrust of the airflow can be adjusted so that when the nozzle is in a horizontal direction, the force of the airflow blowing can balance or be less than the force of the connecting spring deforming. When the nozzle nozzle is rotated to a downward direction, the blowing of the airflow and the weight of the blocking plate both resist the connecting spring, so that the blocking plate is away from the inner channel. When the nozzle is rotated to an upward direction, the gravity of the blocking plate causes it to move into the inner channel. At this time, the force of the airflow blowing is resisted by the gravity of the blocking plate itself and the pulling of the connecting spring, so that the blocking plate slowly returns to the inner channel, so that when the nozzle nozzle is rotated upward, the blocking plate blocks the inner channel again. In the process, since the sliding of the blocking plate is a process, the atomizing airflow can also be ejected from the device during the process of blocking the inner channel, thereby increasing the feasibility of the device.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] Embodiment 1 like Figure 1 - Fig.10 As shown, the respiratory air purifier and disinfector proposed in the first embodiment of the present application includes: The installation shell 1 is installed, and a liquid storage shell 101 and an atomization shell 102 are installed in the installation shell 1. A liquid inlet pipe 104 connected to the inside of the liquid storage shell 101 is installed on the installation shell 1. An air pump 103 is installed in the installation shell 1. The air outlet of the air pump 103 is located in the liquid storage shell 101. A connecting pipe 105 connected to the inside of the atomization shell 102 is installed in the liquid storage shell 101. The liquid storage shell 101 and the atomization shell 102 are separated by a plate body. The connecting pipe 105 runs through the plate body, so that the atomization shell 102 is connected to the liquid storage shell 101. When in use, disinfectant is added to the liquid storage shell 101 through the liquid inlet pipe 104. The instruction manual is attached. In order to facilitate the display, the air pump 103 is arranged in the vertical direction in the figure, but in actual use, it can be arranged in the horizontal direction, and the air pump 103 is connected to the connecting pipe 105 through an additional pipe body to reduce the possibility of water entering the air pump 103. A pipe body is installed on the side wall of the connecting pipe 105, and the connecting pipe 105 is connected to the inside of the liquid storage shell 101 through the pipe body. A one-way valve is installed in the pipe body, so that the disinfectant can only flow from the liquid storage shell 101 to the connecting pipe 105. When in use, the air pump 103 sprays airflow to drive the disinfectant in the connecting pipe 105 to rush into the atomizing shell 102; The shielding cover 2 is installed in the atomizing shell 102. A shielding opening 201 for atomized disinfectant to pass through is provided on the side wall of the shielding cover 2. The projection of the shielding cover 2 on the connecting pipe 105 coincides with the pipe opening of the connecting pipe 105. The shielding cover 2 is located directly above the connecting pipe 105. When in use, when the airflow drives the disinfectant to enter the atomizing shell 102, it collides with the shielding cover 2. Since the airflow sprayed by the air pump 103 is a high-speed airflow, when it drives the disinfectant to collide with the shielding cover 2, the disinfectant is impacted and dispersed into smaller liquid droplets, thereby completing atomization. Under the push of the subsequent airflow, the atomized airflow continues to move outward from the shielding opening 201. The rotating shell 3 is rotatably mounted on the atomizing shell 102. The rotating shell 3 is located at the top of the atomizing shell 102. When the airflow moves out from the mask opening 201, it drives the disinfectant to enter the rotating shell 3. A rotating paddle 301 is rotatably mounted in the connecting tube 105. A connecting rod 302 connected to the rotating shell 3 is mounted on the rotating shaft of the rotating paddle 301. The rotating paddle 301 is located in the connecting tube 105. When the airflow is ejected from the air pump 103, the airflow pushes the rotating paddle 301 to rotate along the tangential direction, thereby enabling the rotating paddle 301 to rotate, thereby driving the connecting rod 302 to rotate, and then driving the rotating shell 3 to rotate through the connecting rod 302; The rotating shell 3 is ball-connected with a nozzle 303, one end of the nozzle 303 is located outside the rotating shell 3, and the other end is located inside the rotating shell 3. A counterweight 304 is installed on the end of the nozzle 303 located inside the rotating shell 3, and a filter plate 305 is installed in the atomizing shell 102. A protruding block 306 for contacting with the counterweight 304 is installed on the filter plate 305. The side wall of the protruding block 306 located in the rotation direction is an inclined surface, and the side wall of the counterweight 304 is also an inclined surface. The counterweight 304 makes the opening of the end of the nozzle 303 located outside at an angle upward under normal conditions. The filter plate 305 is fixedly connected to the atomizing shell 102, so that when the rotating shell 3 rotates, relative movement can occur between the nozzle 303 and the filter plate 305. When in use, the dust in the atomized liquid is shielded by the filter plate 305, which reduces the possibility of dust blocking the nozzle 303 and increases the practicality of the device. When the device is in use, the disinfectant is first injected into the liquid storage shell 101 through the liquid inlet pipe 104, and the disinfectant is driven into the atomization shell 102 by the jet of the air pump 103, and then it collides with the shielding cover 2 to complete the atomization, so that the atomized liquid moves from the cover mouth 201 to the rotating shell 3. During the process, the airflow also drives the rotating paddle 301 to rotate, so that the rotating shell 3 drives the nozzle 303 to rotate in the horizontal direction. While rotating, the filter plate 305 and the rotating shell 3 move relative to each other, so that the protruding block 306 gradually moves toward the counterweight block 304 and resists it, so that the protruding block 306 pushes the counterweight block 304 upward, so that the nozzle 303 rotates downward, and when the protruding block 306 releases the conflict with the counterweight block 304, the counterweight block 304 The force pulls the nozzle 303 to rotate, so that the nozzle 303 rotates upward, so that the nozzle 303 can swing up and down while the rotating shell 3 rotates, which increases the mobility of the nozzle 303, and thus enables the nozzle 303 to spray the atomized liquid in different directions, thereby increasing the diffusion speed of the atomized liquid in the environment, thereby increasing the disinfection efficiency of the device, disinfecting the environment, and facilitating better recovery of the patient. When it is necessary to improve the humidity in the ward, pure water can be added to the device for atomization to increase the humidity in the ward and reduce the possibility of dryness of the patient's respiratory tract. Since the device can atomize the disinfectant, the disinfectant can be hydrogen peroxide or other disinfectants, or pure water can be atomized. In order to facilitate the subsequent description, the disinfectant is described as the main description point; Compared with the prior art, a liquid storage shell 101 and an atomization shell 102 connected by a connecting pipe 105 are provided on the mounting shell 1, and the air pump 103 ejects airflow to drive the disinfectant in the liquid storage shell 101 to move toward the shielding cover 2. When the high-speed airflow drives the disinfectant to collide with the shielding cover 2, it forms smaller water droplets and completes atomization. The atomized disinfectant moves into the rotating shell 3 through the cover mouth 201. The airflow generated by the air pump 103 also drives the paddle 301 to drive the rotating shell 3 to rotate, so that the nozzle 303 can rotate in the horizontal direction. During the rotation, the counterweight block 304 conflicts with or releases the conflict with the protruding block 306, so that the nozzle 303 swings in the vertical direction, which increases the mobility of the nozzle 303 and thereby increases the disinfection efficiency of the device.

[0022] Embodiment 2 like Figure 6 and Figure 7As shown, the second embodiment further discloses the connecting pipe 105, the shielding cover 2 and the nozzle 303 on the basis of the first embodiment. In the second embodiment, the connecting pipe 105 includes a lower tube 1051 and an upper tube 1052, a swivel 4 is rotatably installed between the upper tube 1052 and the lower tube 1051, a rotating paddle 301 is installed on the swivel 4, and a stirring blade 5 is installed on the swivel 4. The swivel 4 forms a connecting piece between the upper tube 1052 and the lower tube 1051, and the swivel 4 also forms a tube wall between the two tube bodies, reducing the possibility of air flow and disinfectant loss. The paddle 301 is installed in the inner cavity of the swivel 4, and the swivel 4 can provide an installation position for the paddle 301. The stirring blade 5 is installed on the outside of the swivel 4 and is located in the liquid storage shell 101. When the paddle 301 rotates, it can also drive the stirring blade 5 to rotate in the liquid storage shell 101, so that the stirring blade 5 rotates and stirs the disinfectant, reducing the possibility of solute precipitation in the disinfectant, so that the disinfectant can better disinfect the environment.

[0023] like Figure 5 and Fig. 9 As shown, in embodiment 2, a vertical rod 6 is installed on the rotating shaft of the rotating paddle 301, the vertical rod 6 is connected to the shielding cover 2, the connecting rod 302 is installed on the top of the shielding cover 2, and an arc block 7 is installed on the inner wall of the shielding cover 2. The vertical rod 6 is connected to the shielding cover 2, and the shielding cover 2 is connected to the connecting rod 302 and the rotating shell 3, so that when the rotating paddle 301 rotates, it also drives the shielding cover 2 to rotate, and an arc block 7 is installed on the inner wall of the shielding cover 2. When the airflow drives the disinfectant to move into the shielding cover 2 and collides with the shielding cover 2, the shielding cover 2 drives the arc block 7 to collide with the airflow through rotation. The arc block 7 makes the inner wall of the shielding cover 2 uneven and has more edges and corners, which can better collide with the airflow to disperse it, so that the atomized liquid can be dispersed into smaller liquid droplets, further increasing the effect of the device on atomizing the disinfectant.

[0024] like Fig.10 As shown, in the second embodiment, an inner channel 8 and an outer channel 9 are provided in the nozzle 303, the inner diameter of the inner channel 8 is smaller than the inner diameter of the outer channel 9, a blocking plate 11 is slidably installed in the inner channel 8 through a connecting spring 10, the diameter of the blocking plate 11 is larger than the inner diameter of the inner channel 8 and smaller than the inner diameter of the outer channel 9, and bristles 12 are installed on the side wall of the blocking plate 11. In normal state, the blocking plate 11 blocks the inner channel 8. When the atomized airflow rushes outward, the blocking plate 11 is pushed outward by the atomized airflow to move into the outer channel 9. Since the inner diameter of the outer channel 9 is larger than the diameter of the blocking plate 11, an external duct appears between the blocking plate 11 and the outer channel 9, so that the atomized airflow can move to the outside. In the process of the atomized airflow moving to the outside, the blocking plate 11 reduces the speed of the atomized airflow moving to the outside, and reduces the possibility that the atomized airflow rushes out too fast, causing the atomized airflow to blow up dust in the environment. When the blocking plate 11 slides in the nozzle 303, the bristles 12 push the dust in the nozzle 303 outward, further reducing the possibility of the nozzle 303 being blocked and increasing the practicality of the device; When in use, the length of the atomizing shell 102 can be adjusted so that the kinetic energy of the atomizing airflow can be consumed as it moves in the atomizing shell 102, further reducing the possibility that the atomizing airflow will disturb the external environment, and the thrust of the airflow can be adjusted so that when the nozzle 303 is in a horizontal direction, the force of the airflow blowing can balance the force of the deformation of the connecting spring 10 or be less than the force of the deformation of the connecting spring 10. When the nozzle 303 is rotated to the downward direction, the blowing of the airflow and the weight of the blocking plate 11 both resist the connecting spring 10, so that the blocking plate 11 is away from the inner channel 8. When the nozzle 303 rotates to an upward direction, the gravity of the blocking plate 11 causes it to move into the inner channel 8. At this time, the force of the airflow blowing is resisted by the gravity of the blocking plate 11 itself and the pulling of the connecting spring 10, so that the blocking plate 11 slowly returns to the inner channel 8. When the nozzle 303 rotates upward, the blocking plate 11 blocks the inner channel 8 again. In the process, since the sliding of the blocking plate 11 is a process, the atomized airflow can also be sprayed out from the device during the process of blocking the inner channel 8, thereby increasing the feasibility of the device.

[0025] like Fig.10 As shown, in embodiment 2, a brush wheel 13 is rotatably mounted on the blocking plate 11, and a guide block 14 is mounted on the brush wheel 13. A spiral groove 15 slidably matched with the guide block 14 is opened in the outer channel 9, so that when the blocking plate 11 slides, the brush wheel 13 rotates in the outer channel 9, and a nylon brush head is also mounted on the side wall of the brush wheel 13. During use, when the blocking plate 11 reciprocates in the nozzle 303, the blocking plate 11 drives the brush wheel 13 to reciprocate in the nozzle 303. When the brush wheel 13 reciprocates in the nozzle 303, the spiral groove 15 guides and pushes the guide block 14 inside the spiral groove 15, so that the brush wheel 13 rotates during the sliding process, so that the brush wheel 13 cleans the inner wall of the nozzle 303 by rotating, thereby further reducing the possibility of the nozzle 303 being blocked and increasing the practicality of the device.

[0026] like Fig. 9As shown, in the second embodiment, a ring sleeve 17 is rotatably mounted on the upper tube 1052 through a torsion spring 16, and an arc plate 18 is mounted on the ring sleeve 17. The arc plate 18 is used to be inserted into the mask opening 201, and the arc surface of the arc plate 18 faces the direction of rotation of the mask opening 201. There are multiple mask openings 201, which are arranged in a circular array along the axial direction of the atomizing shell 102 on the side wall of the shielding cover 2. In normal state, the arc plate 18 is inserted into one of the mask openings 201. When the shielding cover 2 rotates, the inner wall of the mask opening 201 is aligned with the inner wall of the mask opening 201. The arc-shaped side of the arc plate 18 is in conflict, so that the arc plate 18 rotates around the upper tube 1052 to release the obstruction of the inner wall of the mask opening 201. At this time, the torsion spring 16 is deformed. When the next mask opening 201 rotates to align with the arc plate 18, the torsion spring 16 forces the arc plate 18 to rotate and be inserted into the mask opening 201. This cycle is repeated, and the inside of the mask opening 201 is cleaned by repeated insertion of the arc plate 18, which reduces the possibility of dust in the disinfectant blocking the mask opening 201 and increases the practicability of the device.

[0027] Embodiment 3 like Figure 1 - Fig.10 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a concentrating pipe 19 is installed on the shielding cover 2, and one end of the concentrating pipe 19 is connected to the upper pipe 1052. The concentrating pipe 19 is used to block the gap between the upper pipe 1052 and the shielding cover 2. When in use, the concentrating pipe 19 blocks the airflow carrying the disinfectant to other places, thereby reducing the possibility of wasting the disinfectant.

[0028] In the third embodiment, the diameter of the centralizing pipe 19 gradually decreases from the direction toward the shielding cover 2 to the direction away from the shielding cover 2. A recovery hole 20 is opened on the upper tube 1052 at the point where the diameter of the centralizing pipe 19 is the smallest. A one-way valve is installed in the recovery hole 20. The one-way valve allows the disinfectant to flow only from the centralizing pipe 19 to the recovery hole 20. When in use, the centralizing pipe 19 is conical. When the airflow drives the disinfectant to move upward, it is inevitably affected by gravity and part of the disinfectant will fall downward into the centralizing pipe 19. At this time, the conical structure of the centralizing pipe 19 guides the falling disinfectant to the recovery hole 20, so that the disinfectant can flow back into the upper tube 1052 to complete the recovery of the disinfectant, further reducing the loss of the disinfectant during use and increasing the practicality of the device. By setting the one-way valve, the airflow will not spray out from the recovery hole 20 in advance when driving the disinfectant to move, so that the upper tube 1052 can play a better guiding role, increasing the practicality of the device.

[0029] In the third embodiment, a heat-conducting shell 21 for wrapping the air pump 103 is installed in the mounting shell 1, a heat-conducting pipe 22 connected to the atomizing shell 102 is installed on the heat-conducting shell 21, a mounting frame 23 is installed in the atomizing shell 102, the mounting frame 23 is rotatably matched with the connecting rod 302, the mounting frame 23 is tiltedly arranged in the atomizing shell 102, the pipe mouth of the heat-conducting pipe 22 is located at the lowest point of the mounting frame 23, the heat-conducting shell 21 is made of copper, and when in use, when the air pump 103 is in use, the heat generated is absorbed by the heat-conducting shell 21 and guided by the heat-conducting pipe 22, and the heated air is transferred to the atomizing shell 102, and the shape of the mounting frame 23 is as follows: Figure 2 As shown, a plate is installed at the pipe mouth of the heat-conducting pipe 22 located in the atomizing shell 102 for guiding. When the atomized medicine liquid moves upward, it will be blocked by the mounting frame 23, and the medicine liquid will accumulate on the mounting frame 23. This part of the medicine liquid will gather together again, which is not convenient to be continued to be driven by the airflow. Hot air is blown out through the heat-conducting pipe 22, so that the liquid on the mounting frame 23 can be better gathered together and guided by the mounting frame 23 to fall downward. After falling on the plate, it is guided into the heat-conducting pipe 22 and refluxes into the heat-conducting shell 21 to dissipate heat for the air pump 103, thereby increasing the utilization rate of waste liquid by the device. A pipe is installed on the heat-conducting shell 21 for discharging extra waste liquid in the heat-conducting shell 21, thereby increasing the feasibility of the device.

[0030] In the third embodiment, a filter screen 24 is provided on the liquid inlet pipe 104, and a liquid inlet cover 25 is threadedly connected to the liquid inlet pipe 104. The liquid inlet cover 25 is provided with an opening connected to the liquid inlet pipe 104. When in use, a rubber sheet is installed on the liquid inlet cover 25 to seal the opening. When in use, disinfectant is added into the liquid inlet cover 25 through the opening and filtered through the filter screen 24, thereby reducing the dust content of the disinfectant entering the liquid storage shell 101 and increasing the feasibility of the device. When the device has been used for a long time, the connection between the liquid inlet cover 25 and the liquid inlet pipe 104 is released by threading, and the filter screen 24 is exposed and cleaned, thereby increasing the practicality of the device.
