It solves the problems of poor atomization absorption of liquid medicine by the respiratory mask and lack of oxygen supplementation and drug addition functions.

[0004] The above-mentioned existing atomizing mask is composed of an atomizing cup or an atomizing bottle, a catheter, a mask, and an atomizer. When in use, the atomizing tank is connected to the mask, and then connected to the atomizer through the catheter. When working, the atomizer compresses the external filtered air and sprays it into the atomizing bottle through the catheter. The Venturi effect is used to atomize the liquid medicine in the atomizing bottle and then transport it to the mask, so that the patient can inhale it into the lesion for treatment. In addition, an oxygen supply box is connected to the mask for oxygen supply;

[0005] However, the existing nebulizer bottle can only be loaded with one kind of liquid medicine or pre-mixed liquid medicine.

[0055] Please refer to Figure 2-Figure 5 In a further embodiment, liquid guiding grooves 3 812 are opened on both sides of the sealing ring 811, and liquid guiding grooves 3 812 are fixedly connected to the inside of the liquid guiding grooves 812.

[0063] The working principle of the present invention is as follows:

[0064] The present invention cooperates with each other through the provided atomizing bottle 4, end cover 5, liquid containing mechanism 6, plug-in nozzle 7 and switching mechanism 8. Before use, the blocking component 81, the plug-in nozzle 7, the liquid containing mechanism 6 and the end cover 5 are sequentially spliced ​​from bottom to top to the inside of the atomizing bottle 4 to form an atomizing cup. Then, an external hose connects the connector 51 and the mask 3, and the bottom end of the plug-in nozzle 7 and the air outlet port 12 of the atomizing machine 1 are connected through the hose. At this time, the atomizing machine 1 is connected to the power supply and the valve of the oxygen tank 2 is opened, so that the blower 13 inside the atomizing machine 1 inhales the external air from the air inlet port 11 and mixes it with the oxygen entering from the oxygen tank 2, and finally quickly injects it into the inside of the atomizing cup to atomize the liquid medicine inside the atomizing cup through the Venturi effect, and then the mixed air and liquid medicine are quickly injected into the inside of the mask 3, and the patient inhales it into the lesion area for treatment.

[0065] When the blower 13 is in operation, the heat generated by it is conducted to the heat dissipation fins 14, and then conducted to the inside of the wrapping tube 95 by the heat conducting pipe 91, thereby heating the protective tube 96, and then heating the mixed compressed air in the connecting pipe passing through the inside of the protective tube 96, so as to achieve the purpose of preheating, so that the preheated compressed mixed air can enter the inside of the atomizing cup to reduce the surface tension and viscosity of the medicine, so that the medicine particles are more easily dispersed and atomized into finer particles, which not only helps the medicine to volatilize better into a mist, but also the preheated mixed gas and liquid medicine can reduce discomfort and irritation to the patient;

[0066] After the compressed mixed air is connected to the plug-in nozzle 7 through the hose, the air will pass through the inside of the connecting air hole 71 and be ejected from the top port of the plug-in nozzle 7. Since the top of the plug-in nozzle 7 is stuck in the docking groove 64, the air can continue to enter the inside of the cone cap 54 from the port of the docking nozzle 63 and be ejected from the narrow port at the top of the cone cap 54 to collide with the partition 53. At this time, the air will pass through the second liquid guide groove 65 and the upper end slot of the liquid guide groove 1 55, so a Venturi effect will be generated, so that the lower end slots of the liquid guide groove 2 65 and the liquid guide groove 1 55 are respectively sucked into the liquid in the medicine chamber 1 43 and the medicine chamber 2 62;

[0067] After the blower 13 is operated, the upper notches of the second liquid guide groove 65 and the first liquid guide groove 55 generate negative pressure, so that the lower notches of the second liquid guide groove 65 and the first liquid guide groove 55 can inhale the liquid medicine. Whether to select the drive component 82 can be determined based on whether the two liquid medicines in the first medicine chamber 43 and the second medicine chamber 62 will affect each other. If they do not affect each other, the drive component 82 can be rotated. At this time, the user or pharmacist can turn the lever 823 to rotate the clamping ring 821 at the bottom end of the atomizer bottle 4. Then, due to the influence of the magnetic force of the magnetic block 822 and the magnetic block 1 814, the blocking ring 811 also rotates together, and can be observed through the transparent atomizer bottle 4. The liquid guide groove 3 812 is aligned with the liquid guide groove 2 65. At this time, the liquid medicine inside the medicine chamber 1 43 will flow to the upper notch of the liquid guide groove 2 65 through the guidance of the liquid guide block 813 in the liquid guide groove 3 812. This can control the atomization time and sequence of the liquid medicine, which helps to ensure that the drug is more evenly distributed at the lesion, thereby improving the treatment effect; if there is a mutual influence, the drive assembly 82 will not be rotated. After the liquid medicine in the medicine chamber 2 62 is atomized, the drive assembly 82 can be rotated. Therefore, when the patient needs to inhale another liquid medicine, there is no need to replace the atomization cup. This not only avoids the loss of medicine during the replacement of the atomization cup, but also simplifies the operation and improves the flexibility of treatment. Although the embodiments of the present invention have been shown and described, it can be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
