[0035] Reference Figures 1 to 5 In one embodiment of the present invention, a needle-free atomizer comprises:

[0036] The motor housing 100 has a mounting cavity 110 disposed therein and a port 120 disposed at one end thereof, which is connected to the mounting cavity 110 and is used to connect to an external high-pressure gas circuit.

[0037] A compressed gas cylinder 200 is detachably connected to the interface 120;

[0038] The tube structure 300 is disposed in the installation cavity 110 and connected to the interface 120;

[0039] The solenoid valve 400 is provided on the pipe structure 300 or the interface 120 to control the opening and closing of the pipe structure 300;

[0040] The electric push rod 500 is disposed in the installation cavity 110 , wherein the solenoid valve 400 and the switch of the electric push rod 500 are disposed in the motor housing 100 ;

[0041] A battery 600 is electrically connected to the solenoid valve 400 and the electric push rod 500;

[0042] The medicine bottle area shell 700 is detachably connected to the other end of the motor area shell 100 in the longitudinal direction. The medicine bottle area shell 700 is provided with a medicine bottle cavity 710 at one end near the motor area shell 100. An airway structure 720 connected to the tube structure 300 passes through the medicine bottle area shell 700 in the longitudinal direction. The output end of the electric push rod 500 extends into the medicine bottle cavity 710.

[0043] The puncture needle part 800 is detachably provided at the end of the medicine bottle cavity 710 away from the motor housing 100;

[0044] The atomizing head 900 is detachably connected to one end of the medicine bottle area shell 700 away from the motor area shell 100. An atomizing chamber 910 is provided through the middle of the atomizing head 900, wherein the airway structure 720 and the puncture needle part 800 form a correspondence in the atomizing chamber 910.

[0045] In the existing technology, there is a clear boundary between manually operated nebulizers (without air pressure source) and automatically operated nebulizers (with air pressure source). However, even in medical institutions, different working modes may be required depending on the conditions of the scene or the specific needs of use, and the current related nebulizers cannot achieve convenient switching.

[0046] In this invention, the motor housing 100 and the vial housing 700 together form the entire outer shell of the needle-free nebulizer. A mounting cavity 110 is defined within the motor housing 100, and an interface 120 is provided at one end thereof, which connects to the mounting cavity 110. Mounting cavity 110 provides a foundation for the subsequent installation of various electrically driven components.

[0047] The tube structure 300 is arranged in the installation cavity 110 and is connected to the interface 120. The interface 120 is used for, but not limited to, connecting to an external high-pressure gas circuit. The corresponding interface 120 is directly matched with a detachable compressed gas cylinder 200, and the compressed gas cylinder 200 may have a switch for controlling the output gas and shutting off the gas. At this time, the interface 120 forms two working options, specifically connecting to an external high-pressure gas circuit or connecting to the compressed gas cylinder 200. Whether the airflow in the high-pressure gas circuit or the compressed gas cylinder 200 is guided to the tube structure 300 is achieved by the solenoid valve 400. Specifically, the solenoid valve 400 is arranged on the tube structure 300 or the interface 120 to control the conduction and closing of the tube structure 300. A switch for controlling the output gas and shutting off the gas is provided on the compressed gas cylinder 200. During storage, the compressed gas cylinder 200 is closed. When using the compressed gas cylinder 200, after connecting it to the interface 120, the compressed gas cylinder 200 can be switched to an output state, with the solenoid valve 400 controlling the flow of gas from the compressed gas cylinder 200. Preferably, the compressed gas cylinder 200 can be connected not only to the interface 120 but also to the motor housing 100, ensuring the stability of the compressed gas cylinder 200.

[0048] The electric push rod 500 is disposed within the mounting cavity 110 and provides power to move the liquid medicine in the medicine bottle. The electric push rod 500 generally comprises a motor and a screw-like structure. In some cases, a speed reduction mechanism may be provided corresponding to the motor mechanism to enhance the working efficiency of the electric push rod 500.

[0049] The battery 600 is electrically connected to the solenoid valve 400 and the electric push rod 500. The type of the battery 600 can be various and is not particularly limited.

[0050] The medicine bottle area shell 700 is detachably connected to the other end of the motor area shell 100 in the longitudinal direction, thereby forming the outer shell of the entire needle-free nebulizer. A medicine bottle cavity 710 is provided at the end of the medicine bottle area shell 700 near the motor area shell 100, and the medicine bottle cavity 710 is used to accommodate the medicine liquid bottle. The output end of the electric push rod 500 extends into the medicine bottle cavity 710, so that when the electric push rod 500 is working, it can drive the medicine liquid in the medicine liquid bottle out at a preset speed. An airway structure 720 runs through the length of the medicine bottle area shell 700, and the airway structure 720 serves as the basis for the conduction of high-pressure gas. The medicine bottle area shell 700 is detachably provided at the end of the medicine bottle cavity 710 away from the motor area shell 100. After the puncture needle part 800 is installed, it can puncture the medicine liquid bottle, providing a basis for the medicine liquid in the medicine liquid bottle to flow out.

[0051] The atomizing head 900 is detachably connected to the end of the medicine bottle housing 700 away from the motor housing 100. An atomizing chamber 910 is provided through the center of the atomizing head 900. The airway structure 720 and the puncture needle 800 correspond within the atomizing chamber 910. When liquid medicine flows out of the puncture needle 800 and a high-speed airflow is ejected from the airway structure 720, an atomizing airflow with a specific flow rate is formed in the atomizing chamber 910.

[0052] In summary, the airway structure 720 is connected to the tube structure 300, and the tube structure 300 is connected to the interface 120 in the motor area shell 100. The interface 120 can be connected to the external high-pressure air circuit or the compressed gas cylinder 200 as needed, so as to adapt to the usage requirements of different scenarios. Whether the airflow in the high-pressure air circuit or the compressed gas cylinder 200 is guided to the tube structure 300 is achieved by the solenoid valve 400; the work of the electric push rod 500 is to provide power for driving the liquid medicine in the liquid medicine bottle. The switches of the solenoid valve 400 and the electric push rod 500 are set in the motor area shell 100, so that whether the atomization is started is realized by controlling the switch.

[0053] Reference Figure 4 In one embodiment, the pipe structure 300 includes a front section hard pipe 310 and a rear section soft pipe 320 connected to each other, the front section hard pipe 310 and the motor area shell 100 are detachably arranged, the rear section soft pipe 320 is connected to the interface 120, and the solenoid valve 400 is arranged on the rear section soft pipe 320.

[0054] In this embodiment, considering the difficulty in ensuring accurate circumferential alignment of the vial housing 700 and the motor housing 100 during installation, the pipe structure 300 and the motor housing 100 are configured to be removable, thereby improving the installation and alignment of the pipe structure 300. The pipe structure 300 is not limited to a single-piece structure and can include multiple connected sub-pipe structures, and the sub-pipes can be a combination of rigid and flexible materials.

[0055] In one embodiment, a detachable shell is provided on the outer peripheral wall of the motor area shell 100 , and the shell is provided corresponding to the tube structure 300 .

[0056] In this embodiment, the solenoid valve 400 is positioned within the mounting cavity 110, simplifying the installation process of the solenoid valve 400 and making the overall structure of the needle-free atomizer more compact. A removable cover is provided on the motor housing 100. When removed, a window is formed through which the tube structure 300 and the solenoid valve 400 can be installed and maintained.

[0057] In one embodiment, the compressed gas cylinder 200 is a hand-pressed type.

[0058] In this embodiment, the compressed gas cylinder 200 is configured as a manual pressure type, so that the compressed gas cylinder 200 is no longer a disposable product and is pressurized by manual pressure. The manual pressure type compressed gas cylinder 200 operates via a handle and multiple one-way valves, but the specific details are not the focus of the utility model and can be referred to as conventional designs.

[0059] In one embodiment, the puncture needle portion 800 is snap-fitted to the medicine bottle housing 700 .

[0060] In this embodiment, the puncture needle 800 is connected to the vial housing 700 and configured for a snap-on connection, which facilitates the installation process. Specifically, after the vial 010 is installed in the vial housing 700, the puncture needle 800 is directly connected to the vial housing 700, and finally, the atomizer head 900 is connected to the above structure. While the puncture needle 800 is easy to install, the possibility of detachment is also reduced. The snap-on connection between the puncture needle 800 and the vial housing 700 can be various and specific, without limitation.

[0061] In one embodiment, an alignment mark is provided between the medicine bottle area shell 700 and the motor area shell 100 .

[0062] In this embodiment, in consideration of the accurate alignment between the tube structure 300 and the airway structure 720 , an alignment mark is provided between the medicine bottle area shell 700 and the motor area shell 100 to form an alignment guide.

[0063] Reference Figures 1 to 5 In one embodiment, the atomizing head 900 and the medicine bottle area shell 700 as well as the medicine bottle area shell 700 and the motor area shell 100 are snap-connected.

[0064] In this embodiment, the snap-fit ​​method has the advantages of simple processing and operation. Taking the atomizer head 900 and the medicine bottle area shell 700 as an example, the atomizer head 900 is provided with multiple circles of inner grooves, and the medicine bottle area shell 700 is provided with a protruding ring corresponding to the inner grooves, thereby forming a snap-fit ​​fit between the atomizer head 900 and the medicine bottle area shell 700.

[0065] Reference Figures 1 to 5 In one embodiment, a first protruding ring 920 is provided on the circumference of the atomizing head 900 .

[0066] In this embodiment, since the atomizer head 900 and the medicine bottle area shell 700 are snap-fitted, a first protruding ring 920 is provided on the circumference of the atomizer head 900, which can serve as a basis for holding and facilitate the process of detaching the atomizer head 900.

[0067] Reference Figures 1 to 5 In one embodiment, a second protruding ring 730 is provided on the circumference of the medicine bottle area shell 700.

[0068] In this embodiment, since the medicine bottle area shell 700 and the motor area shell 100 are snap-fitted, a second protruding ring 730 is provided on the circumference of the medicine bottle area shell 700, which can serve as a basis for holding and facilitate the process of separating the motor area shell 100.

[0069] In one embodiment, the battery 600 is rechargeable.

[0070] In this embodiment, the battery 600 is limited to a rechargeable type, thereby avoiding the need to replace the battery 600. Specifically, the charging structure of the battery 600 can be set on the outer wall of the motor area shell 100, thereby simplifying the charging process of the battery 600.

[0071] To sum up, the needle-free nebulizer provided by the present invention has an airway structure 720 connected to the tube structure 300, and the tube structure 300 is connected to the interface 120 in the motor area shell 100. According to needs, the interface 120 can be connected to an external high-pressure air circuit or a compressed gas cylinder 200, so as to adapt to the usage requirements of different scenarios. Whether the airflow in the high-pressure air circuit or the compressed gas cylinder 200 is guided to the tube structure 300 is achieved by the solenoid valve 400; the electric push rod 500 works to provide power for driving the medicine in the medicine bottle, and the switches of the solenoid valve 400 and the electric push rod 500 are set in the motor area shell 100, so that whether the atomization is started is realized by manipulating the switch.
