[0042] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0043] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0044] Refer to the attached Figure 1-13 ,

[0045] A medicine atomizing inhaler for children comprises: an atomizer body 1, an atomizing cup 2, a breathing mask 3, a liquid injection component 4, a drying and gas injection component 5, a heating component and a control component.

[0046] The nebulizer body 1 has an air pipe 13 for discharging air. The nebulizer body 1 includes a compressed air mechanism, primarily ensuring that air is expelled from the air pipe 13 at an appropriate rate. Generally, the nebulizer body 1 also includes a cooling fan 11. The nebulizer body 1 is primarily conventional and will not be described in detail. The nebulizer cup 2 is used to hold the medication solution and is connected to the air pipe 13. A breathing mask 3 is connected to the nebulizer cup 2.

[0047] The liquid injection component 4 is used to inject at least liquid into the air pipe 13. The dry air injection component 5 is used to inject at least dry air into the air pipe 13. In this embodiment, the liquid injection component 4 can be a water pump and a water injection pipe 41. The water pump is connected to an external water source or water tank 42, and the water injection pipe 41 is connected to the air pipe 13 through a control component. The dry air injection component 5 includes an air pump body 51 and an air injection pipe 52. The air pump body 51 can be connected to an external dry air source. The air pump body 51 connects the air injection pipe 52 to the air pipe 13 through the control component. The control component is used to control the connection between the liquid injection component 4, the dry air injection component 5, and the atomizer and the air pipe 13. The control component adopts a four-way valve and a control valve that controls the four-way valve. Therefore, dry gas or water alone can be injected into the air pipe 13, water and dry gas can be injected into the air pipe 13 simultaneously, or neither water nor dry gas can be injected into the air pipe 13. The control unit can also control the closing and opening of the gas pipe 13 itself to prevent water from flowing into the compressed gas mechanism along the gas pipe 13. The control unit can use multiple solenoid valves to achieve control of the water injection pipe 41, the gas injection pipe and the gas pipe 13.

[0048] The heating element is used to heat the liquid injected into the gas pipe 13 by the liquid injection element 4. The heating element can be a heating tube or a heating wire. The heating element is mainly used to heat water. The heating element can also heat the water or not, mainly depending on whether the subsequent use of the liquid medicine will be affected by the high temperature and cause poor efficacy.

[0049] When the water pump is connected to an external water tank 42, the water tank 42 can be an external box, a bottle integrated outside the atomizer body 1, or a box integrated inside the atomizer body 1. When the water tank 42 is external, a heating element can be provided in the water tank 42 to control the temperature of the water in the water tank 42. Alternatively, a hot water zone and a cold water zone can be provided in the water tank 42, and the water in both the hot water zone and the cold water zone can be injected into the water injection pipe 41. A flow valve can be used to control the flow rate of the hot and cold water to adjust the water temperature entering the gas transmission pipe 13.

[0050] In solutions other than connecting the air pump body 51 to an external dry air source, the air pump body 51 can also dry the external air before it enters the air injection pipe. For example, the dry air injection device also includes a drying filter structure 53. The air pump body 51 is used to allow air to pass through the drying filter structure 53 and the air injection pipe 52 in sequence and enter the air supply pipe 13, the atomizer cup 2, and the breathing mask 3. The drying filter structure 53 is used to filter dust and water vapor from the air. The drying filter structure 53 is a dryer or a combination of a dryer and a filter. Alternatively, the drying filter structure 53 can also use a desiccant.

[0051] The air pump body 51 and the water pump can be integrated into the atomizer body 1 or externally arranged outside the atomizer body 1 .

[0052] In one of the solutions, the air pump body 51 is arranged inside the atomizer body 1. The atomizer body 1 also has a dry air inlet 54, and the dry filter structure 53 is arranged at the dry air inlet 54, so that the external air enters the atomizer body 1 and then reaches the air supply pipe 13 through the air pump. The integrity of the equipment is increased. Or the dry gas injection part 5 also includes a tapered tube 55, the large end of the tapered tube 55 is connected to the dry air inlet 54, and the small end of the tapered tube 55 is connected to the gas injection pipe 52. Therefore, the arrangement of the tapered tube 55 can make a large amount of external air pass through the dry filter structure 53, and even if the passing efficiency of the dry filter structure 53 is not high, the flow rate of the gas injection pipe can also be guaranteed.

[0053] Specifically, the nebulizer body 1 also has an air inlet 12 and a snap-fit structure, and the snap-fit structure is used to fix the breathing mask 3. When the breathing mask 3 is fixed on the snap-fit structure, the breathing mask 3 is communicated with the air inlet 12. In this embodiment, the snap-fit structure is arranged at the periphery of the air inlet 12, and the snap-fit structure adopts a block with a slot. Since there is a flange on the edge of the breathing mask 3, the flange of the breathing mask 3 can be inserted into the slot to fix the breathing mask 3 on the snap-fit structure. Therefore, the breathing mask 3 is fixed relative to the nebulizer body 1. Since the snap-fit structure is arranged at the periphery of the air inlet 12, after the breathing mask 3 is fixed on the snap-fit structure, the breathing mask 3 will be communicated with the air inlet 12. More specifically, a soft cushion or sealing gasket can be provided in the card slot so that the breathing mask 3 is tightly abutted against the card slot in the card slot, and a soft cushion or sealing gasket can also be provided at the position around the air inlet 12 where the card slot is not provided, so as to improve the sealing performance of the breathing mask 3 relative to the nebulizer body 1. Therefore, after the breathing mask 3 is fixed to the card slot structure, the air inlet 12 of the nebulizer body 1 is blocked, thereby preventing the air supply pipe 13 and the compressed air mechanism in the nebulizer body 1 from becoming wet to the point of exceeding the upper limit of the humidity of the nebulizer body 1 due to the lack of sealing between the air inlet 12 and the breathing mask 3 in a humid environment. Therefore, the normal storage of the nebulizer body 1 can be better improved, and the poor efficacy of the drug caused by excessive humidity during use can be avoided.

[0054] More specifically, the atomizer body 1 further comprises abutment 6. When the respiratory mask 3 is fixed to the snap-fit structure, the respiratory mask 3 and the abutment 6 are tightly sealed. The abutment 6 is elastic. The abutment 6 can be an elastic rubber block. The abutment 6 is tightly abutted against the respiratory mask 3, thereby providing support for the interior of the respiratory mask 3 to prevent it from being flattened by external forces, and providing dual internal and external abutment to enhance sealing performance. The abutment 6 is annular or cylindrical in shape, thereby achieving a completely tight seal against the respiratory mask 3.

[0055] In some other embodiments, the engaging structure and the abutment member 6 are provided at the drying air inlet 54. Therefore, the breathing mask 3 can be placed at the position of the drying air inlet 54. When the air supply pipe 13 needs to be dried, the breathing mask 3 is placed there. Then, the air in the air supply pipe 13 will continuously cooperate with the drying filter structure 53 to be dried. The drying filter structure 53 only dries the air in the air supply pipe 13, thereby quickly drying the air, reducing the amount of air that needs to be dried, and reducing the frequency of use of the drying filter structure 53, thereby increasing the service life of the drying filter structure 53 and ensuring long-term drying efficiency.

[0056] Example 2

[0057] The difference between Example 2 and Example 1 is that:

[0058] The snap-fit structure forms an embedding groove on the nebulizer body 1. The snap-fit structure also forms a buckle on the nebulizer body 1, which can be a protrusion on the nebulizer. An elastic band is generally provided on the respiratory mask 3, which is buckled onto the user's ear. In this embodiment, the elastic band can also be buckled onto the protrusion. A limiting portion larger than the protrusion can be provided on the protrusion to prevent the elastic band from naturally falling off the protrusion. When the respiratory mask 3 is fixed to the snap-fit structure, the edge of the respiratory mask 3 abuts against the embedding groove. Therefore, the embedding groove is used to limit the position of the respiratory mask 3. After the elastic band on the respiratory mask 3 is buckled with the buckle, the respiratory mask 3 is pressed against the nebulizer body 1, and the respiratory mask 3 wraps around the air inlet 12, which can also serve to seal the air inlet 12. In addition, a soft cushion or sealing gasket can also be provided at the embedding groove to increase the sealing between the respiratory mask 3 and the nebulizer body 1, that is, to increase the sealing between the respiratory mask 3 and the air inlet 12.

[0059] The elastic band on the breathing mask 3 is used to tightly press the breathing mask 3 against the atomizer body 1, making the structure simpler and more reliable.

[0060] Example 3

[0061] The difference between Example 3 and Example 1 is that:

[0062] The drying and filtering structure 53 includes: a first filter plate 531, a second filter plate 532 and a scraper 533. The first filter plate 531 and the second filter plate 532 are docked together to form a accommodating chamber 534 for accommodating the desiccant. After the first filter plate 531 and the second filter plate 532 are docked together, the first filter plate 531 and the second filter plate 532 are fixed. The atomizer body 1 has a slot, and the scraper 533 has an insert that is inserted into the slot. After the insert is inserted into the slot, the scraper 533 contacts the filter surface of the first filter plate 531 or the second filter plate 532. The slot can be provided inside or outside the atomizer body 1, and one or two scrapers 533 can be provided. Therefore, the scraper 533 can be provided inside or outside the atomizer body 1. A drive member 7 can be disposed within the atomizer body 1. The drive member 7 is further configured to rotate the first filter plate 531 or the second filter plate 532 so that the scraper 533 contacts at least the first filter plate 531 or the second filter plate 532 located outside the dry air inlet 54. Because the scraper 533 is fixed relative to the atomizer body 1, when the first and second filter plates 531, 532 rotate, the scraper 533 can scrape dust off the first and second filter plates 531, 532. The first and second filter plates 531, 532 are configured to filter air. When the respiratory mask 3 is positioned near the dry air inlet 54, dust or impurities left over from the user's perspiration may remain on the mask. The first and second filter plates 531, 532 are configured to prevent dust and impurities from being filtered out. This serves to dry and clean the air supply pipe 13 and the respiratory mask 3.

[0063] Specifically, the driving member 7 includes a driving motor 71 and a transmission component 72 disposed on the driving motor 71. The driving motor 71 is directly connected to the first filter plate 531 or the second filter plate 532 via the transmission component 72 to rotate the first filter plate 531 or the second filter plate 532. The transmission component 72 adopts one of a gear drive, a pulley drive, or a rope drive.

[0064] More specifically, the transmission component 72 further includes a rotating wheel 73. The rotating wheel 73 is rotatably connected to the dry air inlet 54. The rotating wheel 73 defines a hexagonal groove. The hexagonal groove has a protrusion on one side near the interior of the atomizer body 1. The first and second filter plates 531, 532 are fixed together and inserted into the hexagonal groove, where they abut against the protrusion for position control. The shapes of the first and second filter plates 531, 532 match the hexagonal groove, allowing them to rotate synchronously with the rotating wheel 73. More preferably, the transmission component 72 is driven by a pulley, which connects the drive motor 71 to the rotating wheel 73. Therefore, the drive motor 71 drives the first filter plate 531 and the second filter plate 532 to rotate. After the first filter plate 531 and the second filter plate 532 are fixed, they are plugged into the hexagonal slot. The first filter plate 531 and the second filter plate 532 are detachably connected to the rotating wheel 73, that is, the first filter plate 531 and the second filter plate 532 can be detachably connected to the dry air inlet 54. After a period of use, the first filter plate 531 and the second filter plate 532 can be swapped and reinserted into the hexagonal slot, which facilitates replacement or facilitates replacement of parts if the first filter plate 531 or the second filter plate 532 becomes clogged.

[0065] In some other embodiments, the abutment 6 includes a ring portion 61 and a mesh portion 62. The ring portion 61 is arranged on the atomizer body 1, and the mesh portion 62 is arranged in the middle of the ring portion 61, so that the abutment 6 forms a ventilation cavity. The ring portion 61 and the mesh portion 62 are both elastic. When the breathing mask 3 is pressed against the clamping structure, the ring portion 61 and the mesh portion 62 are pressed against the breathing mask 3. The ring portion 61 and the mesh are both made of elastic rubber material. The driving member 7 is also used to drive the ring portion 61 of the abutment 6 to rotate. The rotation of the abutment 6 can make the ring portion 61 contact the inner wall of the breathing mask 3 and rub against the inner wall of the breathing mask 3 to clean the inner wall of the breathing mask 3. Therefore, when the breathing mask 3 is dried or placed on the air inlet 12 when not in use, the rotation of the abutment 6 can be used to clean the breathing mask 3.

[0066] In a specific embodiment, the ring portion 61 can be fixed to the first filter plate 531 or the second filter plate 532, thereby enabling the driving member 7 to drive the abutment member 6 to rotate. In another specific embodiment, a portion of the ring portion 61 is connected to the rotating wheel 73 via a connecting member, so that the rotation speed of the first filter plate 531 and the second filter plate 532 is different from the rotation speed of the ring portion 61, or the rotation direction of the first filter plate 531 and the second filter plate 532 is different from the rotation direction of the ring portion 61. The scraper 533 is fixed to the ring portion 61, so that the ring portion 61 can clean the respiratory mask 3, and the scraper 533 can clean the first filter plate 531 and the second filter plate 532.

[0067] Specifically, the connecting member can be a differential. Preferably, the connecting member is an annular groove 731 formed on the rotating wheel 73, into which the ring portion 61 is inserted, with some interference fit. Therefore, when the driving motor 71 rotates the rotating wheel 73, it also rotates the ring portion 61, causing the ring portion 61 to abut against the respiratory mask 3, thereby cleaning the inner wall of the respiratory mask 3. Furthermore, external pressure can be applied to the respiratory mask 3, increasing friction between the ring portion 61 and the respiratory mask 3. This prevents the ring portion 61 from rotating relative to the respiratory mask 3, causing the scraper 533 on the ring portion 61 to remain stationary and clean the rotating first and second filter plates 531 and 532.

[0068] More specifically, the ring portion 61 has a high-roughness portion and a low-roughness portion. When the respiratory mask 3 is placed at the dry air inlet 54, the force with which the elastic band on the respiratory mask 3 secures the respiratory mask 3 to the ring portion 61 can be adjusted. When the force is high, the respiratory mask 3 contacts the high-roughness portion, thereby utilizing the friction of the ring portion 61 to prevent the ring portion 61 from rotating relative to the respiratory mask 3. When the force is low, the respiratory mask 3 does not contact the high-roughness portion, thereby utilizing the low friction of the ring portion 61 to allow the ring portion 61 to rotate relative to the respiratory mask 3. Two or more buckles can be provided on the atomizer body 1 to achieve different levels of force in securing the respiratory mask 3 to the ring portion 61.

[0069] In some other embodiments, the abutment member 6 comprises an elastic metal frame and an elastic rubber membrane wrapped around the elastic metal frame; the elastic rubber membrane and the elastic metal frame form a shape-adjustable elastic chamber that contains water. Both the mesh portion and the elastic metal frame are designed to fully contact and clean the inner wall of the respiratory mask.

[0070] In some other embodiments, an exhaust structure is provided on the breathing mask 3, and the exhaust structure is used to discharge the gas in the breathing mask 3 when the user exhales. The exhaust structure adopts a solenoid valve.
