[0026] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The utility model provides a jet atomizer, such as Figure 1 and Figure 2 As shown, it includes a lower shell 10 and an upper shell 20 that are adapted to each other, the lower shell 10 is used to contain medicine, wherein the lower shell 10 includes an arc-shaped outer bottom and an inner bottom, so that the nebulizer can be freely tilted at a certain angle when put down, will not cause overturning when subjected to external force, and can automatically return to the right position when not subjected to external force, an atomizing part is arranged on the inner bottom of the lower shell 10 for atomizing medicine, wherein the upper shell 20 is provided with a mist outlet pipe 21, when the atomizing part atomizes the medicine, the atomized medicine is discharged through the mist outlet pipe 21 for use by the patient.

[0028] In this embodiment, the mist outlet pipe 21 is arranged opposite to the atomizing part. In order to prevent the atomized liquid and atomized particles from entering the mist outlet pipe 21, a blocking member 22 is provided at the inner end of the mist outlet pipe 21 to block the atomized liquid and atomized particles, so that the device can be used more effectively.

[0029] like Figure 3 As shown, the lower shell 10 and the upper shell 20 are connected by threads. Since the device can be tilted at a certain angle, in order to prevent the medicine from leaking from the connection between the lower shell 10 and the upper shell 20, a sealing gasket 30 is arranged between the lower shell 10 and the upper shell 20; specifically, the upper shell 20 is provided with a step at the connection with the lower shell 10, and the sealing gasket 30 is installed on the step. When the upper shell 20 is screwed onto the lower shell 10, the end of the lower shell 10 abuts against the step and contacts with the sealing gasket 30, thereby achieving sealing and preventing side leakage.

[0030] like Figure 3As shown, an air inlet channel 11 connected to the atomizing part is provided on the lower shell 10, and the outlet of the air inlet channel 11 is connected to the atomizing part. The air inlet of the air inlet channel 11 passes through the outer side of the lower shell 10, and an air inlet pipe 12 is installed on the air inlet for connecting the high-pressure gas. Since the high-pressure gas is introduced from the side of the lower shell 10, compared with the traditional nebulizer that generally introduces gas from the bottom, it cannot be placed vertically well. In clinical use, the traditional nebulizer cannot be placed vertically, which easily leads to part of the medicine cannot be completely atomized and causes waste. The present application introduces high-pressure gas from the side, so that the medicine liquid can be completely atomized during use, which is more convenient to use, reduces waste, and saves cost.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the atomizing portion includes a cone 13, which is arranged at the bottom of the inner bottom of the lower shell 10 and is integrally formed. The cone 13 is provided with a through hole 14 along its axial direction, and the through hole 14 is connected to the air inlet channel 11. A conical shell 40 is mounted on the cone 13 and penetrates from top to bottom. The inner wall of the conical shell 40 is fitted with the outer wall of the cone 13, and a plurality of jet grooves 41 are provided on the inner side surface of the conical shell 40 and penetrate along the generatrix direction thereof, wherein a notch 42 is provided at the bottom of the jet groove 41. In order to achieve a better atomization effect, the top of the conical shell 40 is slightly higher than the top of the cone 13.

[0032] In this embodiment, after high-pressure gas is introduced into the air intake pipe 12, the high-pressure gas enters the through hole 14 through the air intake channel 11 and is blown out from the through hole 14. At this time, the air flow velocity at the top of the through hole 14 is faster and the pressure is smaller (Bernoulli principle). The pressure in the lower shell 10 is larger. At this time, under the action of air pressure, the medicine contained in the lower shell 10 will be squeezed into the notch 42 under the action of air pressure, and enter the jet groove 41 through the notch 42, and be discharged from the top of the jet groove 41, and merge with the high-pressure gas at the top of the cone 13. The high-pressure gas will blow the medicine squeezed out of the jet groove 41 to achieve the effect of atomization, and the high-pressure gas will be discharged from the mist outlet pipe 21, and the atomized medicine will be taken out together.

[0033] In order to enable the conical shell 40 to be stably pressed on the cone 13 during use, a U-shaped baffle 43 is provided on the conical shell 40 which is symmetrical along the axis of the conical shell 40, wherein the blocking member 22 abuts against the two ends of the U-shaped baffle 43. When the upper shell 20 is screwed onto the lower shell 10, the blocking member 22 is pressed against the two ends of the U-shaped baffle 43, so that the conical shell 40 can be stably pressed on the cone 13, thereby ensuring the stable operation of the atomizer; further, the setting of the U-shaped baffle 43 can also make the atomization effect of the conical shell 40 better, thereby improving the use effect of the atomizer.

[0034] At the same time, after the medicine in the lower shell 10 is used up, it is convenient to add medicine, wherein a feeding pipe 23 is opened on the upper shell 20, wherein in order to make the structure of the device more stable and more convenient to manufacture, the inner end of the feeding pipe 23 is connected to the blocking member 22.

[0035] like Figure 3 As shown, a rubber plug 24 is provided on the feed port of the feeding pipe 22, wherein the rubber plug 24 is used to seal the feeding pipe 22. In order to prevent the rubber plug 24 from being lost, the rubber plug 24 is connected to the storage pipe 21 through a strap 25.

[0036] It should be understood that the above description of the specific embodiments of the utility model is only for illustrating the technical route and features of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, but the utility model is not limited to the above specific implementation methods. All changes or modifications made within the scope of the claims of the utility model should be included in the protection scope of the utility model.
