[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: like Figures 1 to 4 As shown, the present invention provides a self-priming throat atomization drug delivery device, comprising a cylindrical shell 1, on which a nebulizer 2, a rotating cylinder 3, a valve seat 5 and a suction nozzle 7 are installed from left to right. Among them, the left side of the valve seat 5 is the premixing chamber 31, and the right side of the valve seat 5 is the mixing chamber 51. The valve seat 5 is installed in the premixing chamber 31, and the inner end of the suction nozzle 7 extends into the mixing chamber 51. During operation, the liquid medicine atomized by the nebulizer 2 first enters the premixing chamber 31, then passes through the valve seat 5 into the mixing chamber 51, and is finally inhaled by the user through the suction nozzle 7, thereby achieving the purpose of atomization drug delivery.

[0026] The left end of the shell 1 is provided with an internal thread and an internal step, and the nebulizer 2 is sealed at the left end of the shell 1 through a threaded connection. A drug delivery bottle 21 is threadedly connected to the nebulizer 2, which is convenient for replacing the drug delivery bottle 21 as needed. A switch 22 for controlling the start and stop of the nebulizer 2 is provided at the left end of the nebulizer 2; the switch 22 is set at the end, which is convenient for the user to operate the switch 22 when holding the shell 1 with one hand. A one-way air inlet valve 4 is also installed at the left end of the shell 1, and the inner end of the one-way air inlet valve 4 passes through the inner step of the shell 1. The one-way air inlet valve 4 and the drug outlet of the nebulizer 2 are both connected to the premixing chamber 31.

[0027] Recombination Figure 5 and Figure 6As shown, the rotor 3 is rotatably mounted within the premixing chamber 31 of the housing 1. A bearing 33 is interference-fitted onto each end of the outer wall of the rotor 3. When the rotor 3 is installed in the premixing chamber 31, the bearings 33 at each end of the rotor 3 rest against the inner step of the housing 1 and the valve seat 5, respectively, allowing the rotor 3 to rotate freely. A groove is provided on each end surface of the rotor 3, with a sealing ring installed in the groove. The sealing rings at each end engage with the inner step of the housing 1 and the arc-shaped groove on the valve seat 5, respectively, to improve the sealing between the rotor 3 and the housing 1. An inner drum 34 is embedded within the rotor 3, with evenly distributed stirring blades 35 fixed to the inner wall of the inner drum 34.

[0028] The housing 1 features two symmetrically arranged rectangular escape grooves 11. Opposite the escape grooves 11, the rotating drum 3 includes a circular anti-slip groove 32. When the user holds the housing 1 in one hand, they can rotate the rotating drum 3 with their thumb, leveraging the escape grooves 11. This activates the internal stirring blades 35, ensuring a more uniform distribution of the atomized medication within the premixing chamber 31. The manual design of the rotating drum 3 is engaging, guiding users to better utilize the throat atomization device and enhancing therapeutic efficacy.

[0029] Combine Figures 1 to 4 ,as well as Figure 6 As shown, the valve seat 5 is installed in the shell 1. The valve seat 5 includes a cylinder 52 and a sealing plate 53 fixed to the left end of the cylinder 52. The cylinder 52 and the sealing plate 53 adopt an integrated structure. The cylinder 52 is mounted in the shell 1, and the sealing plate 53 is against the bearing 33 at the right end of the drum 3 to achieve the positioning of the drum 3. A one-way ventilation component 6 is installed on the sealing plate 53. The one-way ventilation component 6 connects the premixing chamber 31 and the mixing chamber 51 in one direction, so that the gas in the premixing chamber 31 enters the mixing chamber 51. A circle of sinking grooves 521 is provided on the outer wall of the cylinder 52. The bottom of the sinking groove 521 is connected to the interior of the cylinder 52 through a small hole 523. An annular breathable cotton 522 is installed in the sinking groove 521, and the breathable cotton 522 does not exceed the sinking groove 521.

[0030] The housing 1 is also provided with a plurality of air distribution holes 12, which face the recessed grooves 521 of the valve seat 5. This allows ambient air to enter the mixing chamber 51 through the air distribution holes 12 of the housing 1 and the breathable cotton pads 522 and small holes 523 on the valve seat 5. An adjustment cylinder 8 is threadedly mounted on the housing 1 and includes a filter screen 81 that faces the air distribution holes 12. Rotating the adjustment cylinder 8 adjusts the intersection area between the filter screen 81 and the air distribution holes 12, thereby adjusting the air intake volume to achieve a predetermined ratio between the air intake of the air distribution holes 12 and the atomized liquid medicine.

[0031] Example 2: Based on the above embodiment 1, combined with Figures 1 to 4 ,as well as Figure 6As shown, the plug 9 in this embodiment is installed at the right end of the shell 1 through a threaded connection, and the inner end of the plug 9 is against one end of the cylinder 52 of the valve seat 5 to achieve the positioning of the valve seat 5. A through hole is provided in the center of the plug 9, and an inner hexagonal groove 521 is provided at the outer end of the through hole. The suction nozzle 7 is inserted into the through hole in the center of the plug 9, and the inner end of the suction nozzle 7 extends into the mixing chamber 51 inside the valve seat 5. A hexagonal step is provided in the middle of the suction nozzle 7, and the hexagonal step cooperates with the inner hexagonal groove 521 at the outer end of the through hole to prevent the suction nozzle 7 from rotating. A sealing ring 71 is also embedded in the middle of the suction nozzle 7, and the sealing ring 71 is squeezed between the outer wall of the suction nozzle 7 and the through hole of the plug 9; the sealing ring 71 is used to improve the sealing between the suction nozzle 7 and the plug 9, and to improve the stability between the suction nozzle 7 and the plug 9.

[0032] The inner end of the nozzle 7 has multiple elastic strips 72, into which a cylindrical honeycomb cotton 73 is inserted. This honeycomb cotton 73, sealed within the nozzle 7, is used to remix and filter the atomized liquid medicine and air. Made of a porous, flexible material, the honeycomb cotton 73 is disposable and can be removed and replaced with a new one before each use.

[0033] Example 3: Based on the above embodiment 2, combined with Figures 6 to 8 As shown, the one-way ventilation assembly 6 in this embodiment includes a pressing plate 61 and an annular sealing gasket 62 positioned between the pressing plate 61 and the sealing plate 53 .

[0034] The pressure plate 61 has a central opening, and the pressure plate 61 is positioned on the right side of the sealing plate 53 by a positioning step. The central hole of the pressure plate 61 is fastened to the sealing plate 53 by screws. An annular groove 611 is provided on the side of the pressure plate 61 close to the sealing plate 53. The annular sealing gasket 62 is made of elastic material and is embedded in the annular groove 611. A plurality of vent holes 531 are provided on the sealing plate 53, and a plurality of sealing covers 621 are provided on the annular sealing gasket 62. The sealing covers 621 correspond to the vent holes 531 one by one, and the sealing covers 621 cover the right end of the vent holes 531. The sealing covers 621 and the annular sealing gasket 62 are connected by at least two connecting strips 622; the connecting strips 622 provide a certain elastic force, so that the sealing cover 621 can be sealed at the right end of the vent hole 531, but under the action of negative pressure, the sealing cover 621 can rotate to the right, so that the vent hole 531 opens a certain gap, realizing one-way flow of gas. The periphery of the pressure plate 61 is provided with an avoidance notch 612 that cooperates with the sealing cover 621 to avoid affecting the rotation of the sealing cover 621 .

[0035] Working principle: After installing the medicine bottle 21, the nebulizer 2 is turned on by the switch 22, and the atomized medicine liquid enters the premixing chamber 31 inside the drum 3; at this time, the user can rotate the drum 3 with one finger to mix the medicine liquid in the premixing chamber 31 through the stirring blade 35; after a certain period of time, the user inhales the atomized medicine liquid through the suction nozzle 7; during the inhalation process, the external gas enters the mixing chamber 51 through the air distribution hole 12, the breathable cotton 522, and the small hole 523. The function of the breathable cotton 522 is to reduce the gas flow rate and generate a certain negative pressure, so that the sealing cover 621 in the one-way ventilation component 6 can be opened under the action of the negative pressure, and part of the atomized medicine liquid will also enter the mixing chamber 51 through the air vent 531, and then be mixed again in the honeycomb cotton 73, and enter the user's throat together to achieve treatment of the throat.

[0036] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
