DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 , is a schematic diagram of the structure of a nebulizer-type respiratory system drug delivery device provided in an embodiment of the present invention. For the sake of convenience of explanation, only the parts related to the embodiment of the present invention are shown, which are described in detail as follows.

[0037] The atomizing breathing system medication device 100 provided by the present invention comprises: a first housing 11 formed by a nozzle cover 101, an intermediate housing 102 connected to the nozzle cover 101, and a bottom housing 103 connected to the intermediate housing 102. It can be understood that the nozzle cover 101, the intermediate housing 102, and the bottom housing 103 can be rotatably connected or plug-in connected to each other to achieve mutual separation between the two.

[0038] Please refer to Figure 1 The nebulizing respiratory system drug delivery device 100 also includes a charging base 200 disposed below the first shell 11. The charging base 200 is electrically connected to the power supply stand 130. The charging base can be connected to an external power source via a USB interface, thereby facilitating the charging and discharging of the nebulizing respiratory system drug delivery device 100.

[0039] See also Figure 2 , which is a schematic diagram of the composition structure of the atomizing respiratory system drug delivery device provided by an embodiment of the present invention, showing the second shell after removing the first shell, and a schematic diagram of the composition structure of the nozzle after removing the nozzle cover to expose the nozzle.

[0040] The first shell 11 contains a second shell 12 which is formed by a nozzle 1011 , a mist channel outer wall 111 connected to the nozzle 1011 , and a power supply bracket 120 connected to the mist channel outer wall 111 .

[0041] In some preferred embodiments, the suction nozzle 1011 is conical or duckbill 1012. It is understandable that the suction nozzle 1011 may also be in other forms.

[0042] See also Figure 3 , which is a schematic diagram of the structure of the atomizing respiratory system medication device provided in an embodiment of the present invention after removing the first shell and the suction nozzle.

[0043] The mist channel outer wall 111 and the power supply bracket 120 and the suction nozzle 1011 connected thereto form a second housing 12. Figure 3 As shown, after removing the suction nozzle 1011, the structure of the built-in medicine bottle 130 and the mist channel 110. In the embodiment, pinch the medicine bottle 130 as shown in FIG. Figure 3 The position shown can be used to remove or insert the medicine bottle.

[0044] See also Figure 4 , which is a schematic diagram of the structure of the atomizing respiratory system medication device provided in an embodiment of the present invention after the second shell is removed.

[0045] like Figure 4As shown, a heating ring 140 is provided at one end of the inner wall 112 of the mist channel. It can be understood that the heating ring 140 can heat the mist in the mist channel 111, thereby enhancing the effect of the medicine and preventing the cold mist from entering the respiratory system. It can be understood that the heating ring 140 can be selected according to the actual situation of the medicine, and the heating ring 140 may not be provided for some medicines.

[0046] like Figure 4 As shown, after the second housing is removed from the atomizing respiratory system drug delivery device provided by the embodiment of the present invention, the structure of the medicine bottle 130, the liquid pressure reducing valve 180, the atomizing module 150, the power supply 160 and the circuit board 161. The medicine bottle 130 is connected to the liquid pressure reducing valve 180, and the liquid pressure reducing valve 180 is connected to the atomizing module 150.

[0047] See also Figure 5 , is a cross-sectional view of the atomizing respiratory system medication device provided by an embodiment of the present invention after the first shell is removed.

[0048] like Figure 5 As shown, the liquid medicine in the medicine bottle 130 enters the liquid medicine tank 153 through the liquid pressure reducing valve 180.

[0049] like Figure 5 As shown, micropores 172 are reserved on the power supply bracket 120 near the micro airflow sensor 170. When mist is sucked through the suction nozzle 1011, gas flow can be formed near the micro airflow sensor 170, which can trigger the atomization module to start, and the medicine in the medicine tank 153 is atomized by the microporous atomization sheet 151, and the mist enters the suction nozzle 1011 through the mist channel 110.

[0050] In some preferred embodiments, the medicine bottle 130 is fixed in the bottling cavity 131. It can be understood that since the medicine bottle 130 is fixed in the bottling cavity 131, the medicine bottle 130 is convenient to take out. By replacing the medicine in the medicine bottle 130, multiple medicines can be used to treat multiple diseases.

[0051] When the tobacco flavor liquid is modified in the medicine bottle 130, it can be used for a new type of health-care cigarette, which can achieve the feeling of smoking and can be used as an electronic cigarette.

[0052] In some preferred embodiments, micropores 172 are further provided on the power supply stand 120. When air is inhaled through the nozzle 1011, a gas flow can be formed near the micro airflow sensor 170, triggering the airflow sensing circuit, starting the atomization module 150, and the medicine liquid in the built-in medicine liquid tank 153 is atomized under the action of the microporous atomization sheet 151. The mist flows through the mist channel 110 into the nozzle 1101 and the oral cavity, and then enters the human respiratory system.

[0053] See also Figure 6and Figure 7 , which are a stereoscopic view, an exploded view and a cross-sectional schematic view of an atomizing module and a liquid pressure reducing valve of an atomizing respiratory system drug delivery device provided in an embodiment of the present invention.

[0054] The atomization module 150 includes a liquid medicine tank 153 , a microporous atomization sheet 151 disposed on the side of the liquid medicine tank 153 , a liquid pressure reducing valve 180 disposed on the upper end of the liquid medicine tank 153 , and a micro airflow sensor 170 disposed on the lower end of the outer side of the liquid medicine tank 153 .

[0055] The liquid pressure reducing valve 180 includes a liquid pressure reducing valve upper cover 184, a needle tube 183 fixed on the liquid pressure reducing valve upper cover 184, and a liquid pressure reducing valve base 185 connected to the liquid pressure reducing valve upper cover 184, the needle tube 183 is connected to the medicine bottle 130, and a ball valve tube 182 and a float 181 loosened or fitted with the ball valve tube 182 are fixed on the liquid pressure reducing base 185, and the float 181 is connected to a soft wire 186.

[0056] It can be understood that before the medicine liquid relies on gravity to pass through the needle tube 183 and the ball valve tube 182 and enter the medicine liquid tank 153, the float 181 relies on its own weight and the ball valve tube 182 to loosen; after the medicine liquid enters the medicine liquid tank 153, the float 181 is gradually pushed back in the medicine liquid tank 153 to gradually contact and fit with the ball valve tube 182, thereby reducing the liquid pressure in the medicine liquid tank 153.

[0057] It can be understood that the mouth of the ball valve tube 182 is formed into a spherical surface, which can fit tightly with the float 181. The liquid pressure in the liquid tank 153 can effectively prevent the microporous atomization sheet 151 from leaking within a controlled range.

[0058] In some preferred embodiments, the microporous atomization sheet 151 is one piece. It is understandable that the microporous atomization sheet 151 is not limited to one piece, and may be two pieces in practice.

[0059] It can be understood that breathing through the nozzle 1011 forms a gas flow near the micro airflow sensor 170, triggering the airflow sensing circuit, starting the atomization module 150, and atomizing the liquid medicine in the built-in liquid medicine tank 153 under the action of the microporous atomization sheet 151. The mist enters the nozzle 1011 and the oral cavity through the mist channel 110, and then enters the human respiratory system.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] Of course, the atomizing breathing system drug delivery device of the present invention can also have a variety of changes and modifications, and is not limited to the specific structure of the above-mentioned embodiment. In short, the protection scope of the present invention should include those changes or substitutions and modifications that are obvious to those of ordinary skill in the art.
