[0037] Please refer to​​​Figure 15 , Figures 1-5 The structural schematic diagram of the atomization device provided by an embodiment of the present application is shown in FIG. 1, Figure 1 and Figure 2 are respectively the exploded structural schematic diagrams of two embodiments of the atomization device, Figure 4 is Figure 3 the sectional view of the atomization device of FIG. 1, Figure 2 is Figure 5 the sectional view of the atomization device of FIG. 2.

[0038] The present application provides an atomization device which can be used for atomization of liquid matrix, and can be applied in different fields, such as medical atomization, electronic atomization, etc. In an embodiment, the atomization device is applied in the field of electronic atomization, and in an embodiment, the atomization device can also be applied in medical equipment for treating diseases of upper and lower respiratory system, to atomize medical liquid, etc.

[0039] The atomization device comprises a housing assembly 10, a control assembly 20 and a pressure regulating valve 30.

[0040] The housing assembly 10 comprises a gas storage cavity 11, a liquid storage cavity 12, an atomization cavity 13 and an atomization outlet 14. The gas storage cavity 11 is used for containing high-pressure gas with a gas pressure higher than atmospheric pressure, for example, as shown in Figure 4 , the gas storage cavity 11 can directly contain high-pressure gas, or as shown in Figures 2-3 , the gas storage cavity 11 can indirectly contain high-pressure gas, for example, a gas cylinder 40 is placed in the gas storage cavity 11, and the gas cylinder 40 is filled with high-pressure gas. The high-pressure gas refers to gas with a gas pressure higher than atmospheric pressure.

[0041] The liquid storage cavity 12 is used for containing liquid matrix, which can be medical liquid, tobacco tar or other liquid matrix that can be atomized. The housing assembly 10 is provided with a first passage 15 capable of communicating the atomization cavity 13 and the gas storage cavity 11, so that when the first passage 15 is communicated, the high-pressure gas in the gas storage cavity 11 or the high-pressure gas in the gas cylinder 40 can flow from the gas storage cavity 11 to the atomization outlet 14 through the atomization cavity 13 under the action of the first pressure difference, and the first pressure difference can specifically refer to the pressure difference between the gas pressure of the gas outlet 32 of the pressure regulating valve 30 and atmospheric pressure.

[0042] The shell assembly 10 further comprises a second passage 16 connecting the atomization cavity 13 and the liquid storage cavity 12. The second passage 16 is not a specific passage structure, but a general term for the passage through which the liquid base flows from the liquid storage cavity 12 to the atomization cavity 13. When the first passage 15 is connected, the high-speed flow of gas to the atomization cavity 13 reduces the pressure in the atomization cavity 13, so that the pressure in the liquid storage cavity 12 is higher than that in the atomization cavity 13. The second pressure difference between the liquid storage cavity 12 and the atomization cavity 13 causes the liquid base to flow through the second passage 16 and spray onto the wall of the atomization cavity 13. The liquid base is atomized into an aerosol by high-speed impact on the wall of the atomization cavity 13. The second pressure difference refers to the difference between the pressure in the liquid storage cavity 12 and the pressure in the atomization cavity 13. The atomization cavity 13 is connected to the atomization outlet 14, and the aerosol finally flows out of the atomization outlet 14 for the user to use.

[0043] The control assembly 20 is arranged on the first passage 15 between the atomization cavity 13 and the gas storage cavity 11, and is used to control the opening and closing of the first passage 15. When the first passage 15 is closed, no negative pressure is generated in the atomization cavity 13, and the liquid base cannot be sprayed to form an aerosol. When the first passage 15 is opened, a negative pressure is generated in the atomization cavity 13, and the liquid base forms an aerosol in the atomization cavity 13. The control assembly 20 can be an electronic control that opens and closes the first passage 15, or a purely mechanical structure that manually controls the opening and closing of the first passage 15. In this application, the control assembly 20 manually controls the opening and closing of the first passage 15 to achieve the endurance of the atomization device without relying on power supply, and to reduce the defects of electronic components in traditional atomization devices, such as lower service life and poorer stability caused by high temperature and high humidity. The structure of the control assembly 20 is described in detail below.

[0044] The pressure regulating valve 30 is arranged on the first passage 15. The pressure regulating valve 30 has an air inlet 31 and an air outlet 32. The air inlet 31 can be connected to the gas storage cavity 11. The air outlet 32 of the pressure regulating valve 30 is connected to or disconnected from the atomization cavity 13 through the control assembly 20. The pressure regulating valve 30 is used to regulate the air pressure at the air outlet 32 to a preset air pressure. The preset air pressure can be a certain range of air pressure values, and the air pressure at the air outlet 32 fluctuates within the range, so that the user does not feel that the air pressure fluctuates greatly.

[0045] The atomization device of the present application arranges the pressure regulating valve 30 on the first passage 15 between the atomization cavity 13 and the gas storage cavity 11. The pressure regulating valve 30 can regulate the air pressure at the air outlet 32 of the pressure regulating valve 30, so that the air pressure of the gas flowing out of the air outlet 32 of the pressure regulating valve 30 is relatively stable. The initial air pressure is not too large when the user uses it, and the air pressure fluctuates little during use, so the taste consistency is good.

[0046] The atomizing device of the application is based on the principle of jet atomization, and is based on a pure mechanical structure design. Compared with heating atomization, ultrasonic atomization and other atomization devices dependent on power supply, the atomization device can reduce the user's anxiety about battery endurance.

[0047] Please refer to Figures 4-5 , Figures 6-8 for Figure 6 a cross-sectional view of the pressure regulating valve 30, Figure 5 for Figure 7 a cross-sectional view of the valve body 33, Figure 6 for Figure 8 a cross-sectional view of the core body 35. In an embodiment, the pressure regulating valve 30 includes a valve body 33, a first elastic member 34 and a core body 35. The valve body 33 is provided with a pressure regulating chamber 331 and a constant pressure chamber 332 connected in communication. The pressure regulating chamber 331 is arranged on the side close to the gas storage cavity 11, and the constant pressure chamber 332 is arranged on the side away from the gas storage cavity 11.

[0048] The first elastic member 34 and the core body 35 are both arranged in the pressure regulating chamber 331, and the two ends of the first elastic member 34 are connected with the cavity wall of the pressure regulating chamber 331 and the core body 35 respectively. Specifically, the first elastic member 34 is connected with the first side 3511 of the core body 35 facing the air inlet 31, and the first elastic member 34 has an elastic restoring force capable of driving the core body 35 to move towards the air outlet 32. In this embodiment, the first elastic member 34 can be a spring, and the spring is always in a compressed state.

[0049] In an embodiment, the core body 35 can include a first sliding part 351 and a second sliding part 352 connected in communication, and the first sliding part 351 is arranged at one end of the second sliding part 352 close to the constant pressure chamber 332. Part of the structure of the first sliding part 351 is arranged on the side wall of the second sliding part 352 in a radial direction, so that the core body 35 can form a "T" type cross-sectional structure. The end face of the first sliding part 351 close to the second sliding part 352 is the first side 3511, and the end face of the first sliding part 351 away from the second sliding part 352 is the second side 3512. The first elastic member 34 is sleeved on the second sliding part 352, one end of the first elastic member 34 is arranged on the first side 3511 of the first sliding part 351, and the other end of the elastic member is arranged on the inner wall of the pressure regulating chamber 331 away from the constant pressure chamber 332.

[0050] The first airflow passage 353 is provided in the core 35 and penetrates the first sliding part 351 and the second sliding part 352. The outlet end of the first airflow passage 353 is arranged on the second side 3512 of the first sliding part 351 and communicates with the constant pressure chamber 332. The first side 3511 of the core 35 is subjected to the elastic restoring force of the first elastic member 34, and the second side 3512 of the core 35 is subjected to the gas pressure of the constant pressure chamber 332, so that the core 35 can be closed or opened under the combined action of the first elastic member 34 and the gas pressure of the constant pressure chamber 332.

[0051] In an embodiment, the cavity wall of the pressure regulating chamber 331 forms a straight sliding channel, that is, the cavity wall of the pressure regulating chamber 331 limits the radial direction of the core 35, so that the core 35 can reciprocate straightly in the pressure regulating chamber 331 towards the direction of approaching or moving away from the gas inlet 31. The sliding track of the core 35 is guided by the pressure regulating chamber 331, so that the sliding of the core 35 is more stable. The side wall of the first sliding part 351 of the core 35 can be closely combined with the side wall of the pressure regulating chamber 331, so that the gas pressure regulated by the pressure regulating valve 30 is more accurate.

[0052] In an embodiment, the inner wall of the valve body 33 is provided with a first cavity wall 3311 separating the pressure regulating chamber 331 and the constant pressure chamber 332, which can limit the sliding of the core 35 to the side of the gas outlet 32, that is, the first cavity wall 3311 can also limit the axial sliding of the core 35. The first cavity wall 3311 is provided with a gas hole 3313, which communicates the pressure regulating chamber 331 and the constant pressure chamber 332, and the outlet end of the first airflow passage 353 communicates with the constant pressure chamber 332 through the gas hole 3313. When the second side 3512 of the core 35 is in contact with the first cavity wall 3311 of the pressure regulating chamber 331, the gas hole 3313 can expose a part of the second side 3512 of the core 35, and the outlet end of the first airflow passage 353 of the core 35 communicates with the gas hole 3313, so that the gas entering the first airflow passage 353 from the gas inlet 31 of the valve body 33 can always flow to the constant pressure chamber 332 through the first airflow passage 353, and the second side 3512 of the core 35 can always be subjected to the pressure of the constant pressure chamber 332 at least partially.

[0053] In an embodiment, the second cavity wall 3312 is provided at the gas inlet 31, and the second cavity wall 3312 includes a first slope 3314. The second sliding part 352 of the core 35 has a second slope 3521 towards the outer side of the gas inlet 31, and the first slope 3314 and the second slope 3521 are matched and oppositely arranged, that is, the slope and shape of the first slope 3314 and the second slope 3521 are the same, for example, in an embodiment, the second cavity wall 3312 is a ring-shaped slope, and the second slope 3521 is also a ring-shaped slope. Figure 6 ​

[0054] The air inlet end of the first airflow channel 353 is arranged on the end surface of the second slope 3521, and the air outlet end of the first airflow channel 353 is arranged on the end surface of the first slope 3314. Figures 6-8 In the embodiment, the first airflow channel 353 has a plurality of air inlet ends, and the plurality of air inlet ends are evenly distributed in the circumferential direction on the side of the core 35 close to the air inlet 31. When the first slope 3314 and the second slope 3521 are in the abutting state, the first slope 3314 blocks the air inlet end of the first airflow channel 353 on the second slope 3521, and the end of the side of the core 35 away from the air outlet 32 blocks the air inlet 31 of the valve body 33, and when the first slope 3314 and the second slope 3521 are in the non-abutting state, the air inlet end of the first airflow channel 353 is in an open state.

[0055] The working principle of the pressure regulating valve 30 is shown in Figures 6-8 , taking the first elastic member 34 as an example. Figure 9 (a) is the initial state of the pressure regulating valve 30, and in the initial state, it is assumed that the rated preset air pressure is P 额 , the spring coefficient of the spring 341 is K, the compression amount of the spring 341 is x, the area of the pressure bearing surface of the second side 3512 of the core 35 is S, and the initial pressure in the gas storage cavity 11 is P 气 . In the initial state, the elastic restoring force of the spring 341 is greater than or equal to the pressure bearing pressure of the second side 3512 of the core 35, so that the second side 3512 of the core 35 is tightly pressed against the first cavity wall 3311.

[0056] Figure 9 (b) is the pressure increasing state of the pressure regulating valve 30, and when the user presses the start switch of the atomization device, the first passage 15 between the atomization cavity 13 and the gas storage cavity 11 is communicated. The gas in the gas storage cavity 11 enters the constant pressure chamber 332 along the first airflow channel 353 of the core 35, and the pressure P in the constant pressure chamber 332 continuously rises, and when P*S>K*x, that is, the pressure bearing pressure of the second side 3512 of the core 35 is greater than the elastic restoring force of the spring 341, the core 35 starts to move in the direction close to the air inlet 31 of the valve body 33.

[0057] Figure 9 (c) is the state of the pressure regulating valve 30 reaching the rated pressure, and when the pressure P in the constant pressure chamber 332 increases to P 额 , the linear movement distance of the core 35 is L, at this time, the first slope 3314 and the second slope 3521 are in the abutting state, the air inlet end of the first airflow channel 353 of the core 35 is blocked, and the pressure in the constant pressure chamber 332 no longer increases, at this time, P*S=K*L, that is, P 额 =(K*L) / S, that is, the rated preset air pressure can be controlled by reasonably designing the spring coefficient K of the spring 341, the maximum movement distance L of the core 35, and the pressure bearing surface S of the core 35.

[0058] Figure 9 (d) for pressure reducing valve 30 pressure reducing state, after the high pressure gas in the constant pressure chamber 332 along the valve body 33 gas outlet 32 release, the pressure P in the constant pressure chamber 332 starts to reduce, at this time P*S < K*L, that is, the second side 3512 of the core 35 pressure is less than the elastic recovery force of the spring 341, the core 35 starts to move along the side close to the gas outlet 32 direction straight, the first slope 3314 and the second slope 3521 are in a non-adhesion state, the first gas flow channel 353 of the core 35 is opened, the pressure in the constant pressure chamber 332 starts to rise again, returns to Figure 9 (b) pressure increasing state, thus the reciprocating cycle realizes the constant pressure control of the constant pressure chamber 332, and can realize the control of the gas pressure at the gas outlet 32 of the constant pressure chamber 332 by setting the coefficient K of the spring 341, the maximum movement distance L of the core 35 and the pressure bearing surface S of the core 35.

[0059] The pressure regulating valve 30 adjusts the gas pressure to the preset pressure by the pure mechanical structure, so that the gas pressure flowing out of the gas outlet 32 of the pressure regulating valve 30 is relatively stable, the initial gas pressure is not too large when the user uses it, and the gas pressure fluctuation is small during use, and the taste consistency is good. And the pure mechanical structure does not depend on the use of power supply, which can reduce the user's anxiety about battery life.

[0060] Please refer to Figure 9 In an embodiment, the gas storage cavity 11 is provided with a gas cylinder 40, and the gas cylinder 40 contains high-pressure gas with a pressure higher than atmospheric pressure. The high-pressure gas may, for example, be carbon dioxide gas, and the gas pressure is usually 100-250 Bar. The gas cylinder 40 can be made of stainless steel and formed by cold stamping and extrusion process. The top of the gas cylinder 40 has a sealing port, and the sealing material is usually aluminum or other soft metal material.
