[0003] Nebulizers can typically deliver medications directly and accurately to the affected area of ​​the respiratory tract for treatment, thereby enhancing drug efficacy and reducing adverse reactions. Nebulizers are widely used in the treatment and research of bronchopulmonary diseases, particularly bronchial asthma and lung cancer. Commonly used nebulizers in clinical applications include compressed nebulizers and ultrasonic nebulizers.

[0004] The compressed atomizer device generates negative pressure near the orifice of a fine-pore tube by passing compressed air at high speed. The liquid medicine in the liquid storage chamber collides with the obstruction with the high-speed airflow, breaking it into liquid particles of different sizes and then spraying it out at a moderate speed to be delivered to the patient.

[0005] Typically, during the use of a compressed atomizer, the air pressure in the air storage chamber will gradually decay. Since the air pressure decay is unstable and fluctuates greatly, the taste consistency when the user uses it is poor.

References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0040] Please refer to Figures 1 to 5, Figure 1 is a structural schematic diagram of an atomization device provided in an embodiment of the present application, Figures 2 and 4 are exploded structural schematic diagrams of two embodiments of the atomization device, Figure 3 is a cross-sectional view of the atomization device of Figure 2, and Figure 5 is a cross-sectional view of the atomization device of Figure 4.

[0041] The present application provides an atomization device that can be used to atomize liquid substrates. The atomization device can be specifically applied in different fields, such as medical atomization and electronic atomization. In one embodiment, the atomization assembly is applied in the field of electronic atomization. In another embodiment, the atomization assembly can also be applied to medical equipment for treating upper and lower respiratory system diseases to atomize medical liquids, etc.

[0042] The atomizing device includes a housing assembly 10 , a control assembly 20 and a pressure regulating valve 30 .

[0043] The housing assembly 10 includes a gas storage chamber 11, a liquid storage chamber 12, an atomization chamber 13, and an atomization outlet 14. The gas storage chamber 11 is used to accommodate high-pressure gas at a pressure higher than atmospheric pressure. For example, as shown in Figures 2-3, the gas storage chamber 11 can directly accommodate high-pressure gas, or, as shown in Figures 4-5, the gas storage chamber 11 can indirectly accommodate high-pressure gas, such as by placing a gas cylinder 40 filled with high-pressure gas in the gas storage chamber 11. High-pressure gas refers to gas at a pressure higher than atmospheric pressure.

[0044] The liquid storage chamber 12 is used to accommodate a liquid matrix, which can be, for example, a medicinal liquid, tobacco oil, or other liquid matrix that can be atomized. A first passage 15 is provided in the housing assembly 10, which can connect the atomization chamber 13 with the gas storage chamber 11. When the first passage 15 is connected, the high-pressure gas in the gas storage chamber 11 or the high-pressure gas in the gas cylinder 40 can flow from the gas storage chamber 11 through the atomization chamber 13 to the atomization outlet 14 under the action of a first pressure difference. The first pressure difference can specifically refer to the pressure difference between the gas pressure at the outlet 32 ​​of the pressure regulating valve 30 and atmospheric pressure.

[0045] A second passage 16 is also provided in the housing assembly 10, connecting the atomizing chamber 13 and the liquid storage chamber 12. The second passage 16 does not refer to a specific passage structure, but rather refers to a general term for the passage through which the liquid matrix flows from the liquid storage chamber 12 to the atomizing chamber 13. When the first passage 15 is connected, the gas flows into the atomizing chamber 13 at high speed, which reduces the pressure in the atomizing chamber 13, so that the pressure in the liquid storage chamber 12 is higher than the pressure in the atomizing chamber 13. Under the action of the second pressure difference between the liquid storage chamber 12 and the atomizing chamber 13, the liquid matrix can flow through the second passage 16 and be sprayed onto the cavity wall of the atomizing chamber 13. The liquid matrix impacts the cavity wall of the atomizing chamber 13 at high speed and is atomized into an aerosol. That is, the second pressure difference specifically refers to the difference between the pressure in the liquid storage chamber 12 and the pressure in the atomizing chamber 13. The atomizing chamber 13 is connected to the atomizing outlet 14, and the aerosol ultimately flows out of the atomizing outlet 14 for use by the user.

[0046] The control component 20 is arranged on the first passage 15 between the atomizing chamber 13 and the gas storage chamber 11 to control the on-off of the first passage 15. When the first passage 15 is closed, no negative pressure is generated at the atomizing chamber 13, and the liquid matrix will not be ejected to form an aerosol; when the first passage 15 is opened, a negative pressure is generated in the atomizing chamber 13, and the liquid matrix forms an aerosol in the atomizing chamber 13. The control component 20 can be an electrically controlled on-off of the first passage 15, or a purely mechanical structure to manually control the on-off of the first passage 15. In the present application, the control component 20 is a manually controlled on-off of the first passage 15 to achieve an atomizing device that does not rely on power supply endurance, and to reduce the defects of electronic components in traditional atomizing devices that are easily caused by high temperature and high humidity, such as low lifespan and poor stability. The structure of the control component 20 is described in detail below.

[0047] The pressure regulating valve 30 is disposed on the first passage 15 and has an air inlet 31 and an air outlet 32. The air inlet 31 can communicate with the air storage chamber 11, and the air outlet 32 ​​of the pressure regulating valve 30 can be connected to or isolated from the atomizing chamber 13 via the control assembly 20. The pressure regulating valve 30 is used to adjust the air pressure at the air outlet 32 ​​to a preset air pressure. The preset air pressure can be a pressure value within a certain range, and the air pressure at the air outlet 32 ​​fluctuates within this range without causing the user to feel a large pressure fluctuation.

[0048] The atomization device of the present application sets a pressure-regulating valve 30 on the first passage 15 between the atomization chamber 13 and the gas storage chamber 11. The pressure-regulating valve 30 can adjust the air pressure at the air outlet 32 ​​of the pressure-regulating valve 30, so that the pressure of the gas flowing out of the air outlet 32 ​​of the pressure-regulating valve 30 is relatively stable. The initial air pressure will not be too high when the user uses it, and the air pressure fluctuation is small during use, and the taste consistency is better.

[0049] The atomization device of the present application is based on the principle of jet atomization and a purely mechanical structural design. Compared with atomization devices such as heating atomization and ultrasonic atomization that rely on power supply, it can reduce users' anxiety about battery life.

[0050] Please refer to Figures 6 to 8. Figure 6 is a cross-sectional view of a pressure regulating valve 30 provided in one embodiment of the present application, Figure 7 is a cross-sectional view of the valve body 33 of Figure 6, and Figure 8 is a cross-sectional view of the core 35 of Figure 6. In one embodiment, the pressure regulating valve 30 includes a valve body 33, a first elastic member 34, and a core 35. A pressure regulating chamber 331 and a constant pressure chamber 332 are provided in the valve body 33. The pressure regulating chamber 331 is arranged on a side close to the air storage chamber 11, and the constant pressure chamber 332 is arranged on a side away from the air storage chamber 11.

[0051] The first elastic member 34 and the core 35 are both disposed in the pressure-regulating chamber 331, with both ends of the first elastic member 34 connected to the cavity wall of the pressure-regulating chamber 331 and the core 35, respectively. Specifically, the first elastic member 34 is connected to a first side 3511 of the core 35 facing the air inlet 31. The first elastic member 34 has an elastic restoring force capable of driving the core 35 toward the air outlet 32. In this embodiment, the first elastic member 34 may be a spring, and the spring is always in a compressed state.

[0052] In one embodiment, the core 35 may include a first sliding portion 351 and a second sliding portion 352 connected to each other, with the first sliding portion 351 being disposed at one end of the second sliding portion 352 proximal to the constant pressure chamber 332. A portion of the first sliding portion 351 protrudes radially from the sidewall of the second sliding portion 352, so that the core 35 may form a "T"-shaped cross-sectional structure. The end surface of the first sliding portion 351 proximal to the second sliding portion 352 is a first side 3511, and the end surface of the first sliding portion 351 distal to the second sliding portion 352 is a second side 3512. The first elastic member 34 is sleeved on the second sliding portion 352, with one end of the first elastic member 34 disposed on the first side 3511 of the first sliding portion 351, and the other end of the elastic member disposed on the inner wall of the pressure regulating chamber 331 distal to the constant pressure chamber 332.

[0053] A first airflow channel 353 is defined within the core 35, extending through the first sliding portion 351 and the second sliding portion 352. The outlet of the first airflow channel 353 is located on the second side 3512 of the first sliding portion 351 and communicates with the constant pressure chamber 332. The first side 3511 of the core 35 is subject to the elastic restoring force of the first elastic member 34, while the second side 3512 of the core 35 is subject to the gas pressure of the constant pressure chamber 332. The core 35 can block or open the inlet of the first airflow channel 353 under the combined action of the first elastic member 34 and the gas pressure of the constant pressure chamber 332.

[0054] In one embodiment, the walls of the pressure-regulating chamber 331 form a linear sliding channel. Specifically, the walls of the pressure-regulating chamber 331 limit the radial direction of the core 35, allowing the core 35 to slide linearly back and forth within the pressure-regulating chamber 331 toward or away from the air inlet 31. The pressure-regulating chamber 331 guides the sliding trajectory of the core 35, making the sliding of the core 35 more stable. The sidewalls of the first sliding portion 351 of the core 35 can closely mate with the sidewalls of the pressure-regulating chamber 331, ensuring more accurate adjustment of the gas pressure by the pressure-regulating valve 30.

[0055] In one embodiment, a first cavity wall 3311 is provided on the inner wall of the valve body 33 to separate the pressure-regulating chamber 331 from the constant-pressure chamber 332. The first cavity wall 3311 can restrict the sliding of the core 35 toward the air 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 an air hole 3313, which connects the pressure-regulating chamber 331 and the constant-pressure chamber 332. The air outlet end of the first airflow channel 353 is connected to the constant-pressure chamber 332 through the air hole 3313. When the second side 3512 of the core body 35 contacts the first cavity wall 3311 of the pressure regulating chamber 331, the air hole 3313 can expose a portion of the second side 3512 of the core body 35, and the air outlet end of the first air flow channel 353 of the core body 35 is connected to the air hole 3313, so that the gas entering the first air flow channel 353 from the air inlet 31 of the valve body 33 can always flow into the constant pressure chamber 332 through the first air flow channel 353, and at least a part of the end face of the second side 3512 of the core body 35 can always be subjected to the pressure of the constant pressure chamber 332.

[0056] In one embodiment, a second cavity wall 3312 is provided at the air inlet 31, and the second cavity wall 3312 includes a first slope 3314. The second sliding portion 352 of the core body 35 has a second slope 3521 on the outer side facing the air inlet 31. The first slope 3314 matches the second slope 3521 and is arranged relative to each other, that is, the slope and shape of the first slope 3314 and the second slope 3521 are the same. For example, in the embodiments of Figures 6-8, the second cavity wall 3312 is an annular slope, and the second slope 3521 is also an annular slope.

[0057] The air inlet end of the first air flow channel 353 is disposed on the end surface of the second slope 3521. In the embodiments of Figures 6-8 , the first air flow channel 353 has multiple air inlet ends, which are evenly distributed along the circumference on the side of the core 35 near the air inlet 31. When the first slope 3314 and the second slope 3521 are in contact, the first slope 3314 blocks the air inlet end of the first air flow channel 353 located on the second slope 3521, and the end of the core 35 away from the air outlet 32 ​​blocks the air inlet 31 of the valve body 33. When the first slope 3314 and the second slope 3521 are not in contact, the air inlet end of the first air flow channel 353 is open.

[0058] The operating principle of the pressure regulating valve 30 is shown in Figure 9 , using the example of a spring 341 as the first elastic member 34. Part (a) of Figure 9 illustrates the initial state of the pressure regulating valve 30. In this initial state, assuming the rated preset air pressure is Prated, the spring coefficient of spring 341 is K, the compression of 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 within the air storage chamber 11 is Pgas. In this initial state, the elastic restoring force of spring 341 is greater than or equal to the pressure of the second side 3512 of the core 35, causing the second side 3512 of the core 35 to press tightly against the first chamber wall 3311.

[0059] Part (b) of Figure 9 shows the pressure-increasing state of the pressure regulating valve 30. When the user presses the start switch of the atomizer device, the first passage 15 between the atomizing chamber 13 and the gas storage chamber 11 is connected. The gas in the gas storage chamber 11 enters the constant pressure chamber 332 along the first airflow channel 353 of the core body 35. The pressure P in the constant pressure chamber 332 continues to rise. When P*S>K*x, that is, the pressure on the second side 3512 of the core body 35 is greater than the elastic restoring force of the spring 341, the core body 35 begins to move in the direction close to the air inlet 31 of the valve body 33.

[0060] Part (c) in Figure 9 shows the state where the pressure regulating valve 30 reaches the rated pressure. When the pressure P in the constant pressure chamber 332 increases to Prated, the linear movement distance of the core 35 is L. At this time, the first slope 3314 and the second slope 3521 are in a fitted state, and the air inlet end of the first air flow channel 353 of the core 35 is blocked. The pressure in the constant pressure chamber 332 no longer increases. At this time, P*S=K*L, that is, Prated=P=(K*L) / S, that is, the reasonable design of the spring 341 coefficient K, the maximum movement distance L of the core 35, and the pressure-bearing surface S of the core 35 can control the rated preset air pressure.

[0061] Part (d) in FIG9 shows the state where the pressure of the pressure regulating valve 30 is reduced. After the high-pressure gas in the constant pressure chamber 332 is released along the air outlet 32 ​​of the valve body 33, the pressure P in the constant pressure chamber 332 begins to decrease. At this time, P*S<K*L, that is, the bearing pressure of the second side 3512 of the core body 35 is less than the elastic restoring force of the spring 341. The core body 35 begins to move linearly in the direction close to the air outlet 32. The first slope 3314 and the second slope 3521 are in a non-fitting state. The air inlet end of the first air flow channel 353 of the core body 35 is opened, and the pressure in the constant pressure chamber 332 begins to rise again, returning to the pressure increasing state in part (b) in FIG9. This reciprocating cycle realizes constant control of the pressure in the constant pressure chamber 332, and the air pressure at the air outlet 32 ​​of the constant pressure chamber 332 can be controlled to be the rated preset air pressure by setting the coefficient K of the spring 341, the maximum movement distance L of the core body 35, and the pressure-bearing surface S of the core body 35.

[0062] The pressure regulating valve 30 uses a purely mechanical structure to adjust the air pressure to a preset pressure. This ensures that the pressure of the gas flowing out of the outlet 32 ​​of the pressure regulating valve 30 is relatively stable. The initial air pressure during use is not excessive, and the air pressure fluctuates slightly during use, resulting in a more consistent taste. Furthermore, the purely mechanical structure does not rely on power, which can reduce user concerns about battery life.

[0063] Please refer to Figures 5 to 7. In one embodiment, a gas cylinder 40 is provided in the gas storage chamber 11. The gas cylinder 40 contains high-pressure gas with a pressure higher than atmospheric pressure. The high-pressure gas can be, for example, carbon dioxide gas. The gas pressure is usually 100Bar-250Bar. The gas cylinder 40 can be made of stainless steel and formed by cold stamping and extrusion. The top of the gas cylinder 40 has a sealing port. The sealing material is usually aluminum or other soft metal materials. It is usually sealed by a spot welding process after the high-pressure gas is injected.

[0064] In one embodiment, the end of the valve body 33 of the pressure regulating valve 30 close to the gas storage chamber 11 is a puncture end 333, and the puncture end 333 is provided with an air inlet 31 passing through the puncture end 333. At least part of the structure of the puncture end 333 is arranged in the gas storage chamber 11 to puncture the sealing port installed on the gas cylinder 40, so that the high-pressure gas in the gas cylinder 40 can enter the pressure regulating valve 30 through the air inlet 31.

[0065] In other embodiments, the pressure regulating valve 30 may not be provided with the piercing end 333 , and a piercing member may be separately provided in the housing assembly 10 .

[0066] In one embodiment, the gas cylinder 40 is detachably connected to the housing assembly 10. A gas cylinder 40 mounting channel is provided within the housing assembly 10, communicating with the outside world. The gas cylinder 40 can be inserted into the gas cylinder 40 mounting channel and moved along the gas cylinder 40 mounting channel into the gas storage chamber 11. The sealed opening of the gas cylinder 40 is punctured by the piercing end 333 in the gas storage chamber 11. By detachably connecting the gas cylinder 40 and the housing assembly 10, the gas cylinder 40 can be replaced after the gas in the gas cylinder 40 is exhausted. The user can purchase the gas cylinder 40 separately for replacement without having to purchase a new atomizer device, thereby reducing the user's maintenance costs for the atomizer device.

[0067] In one embodiment, as shown in Figures 10 and 11, the housing assembly 10 includes a detachable outer shell 50 and a base 60. The detachable connection between the outer shell 50 and the base 60 can be achieved by a snap-fit, threaded connection, interference fit, or the like. In one embodiment, the outer shell 50 and the base 60 are threadedly connected, which can improve the sealing of the gas storage chamber 11. As shown in the embodiment of Figures 3, 10, and 11, the outer shell 50 is provided with an air storage chamber 11 and a liquid storage chamber 12. The air storage chamber 11 is directly filled with high-pressure gas. The base 60 is provided with a one-way valve 61 for inflating the gas storage chamber 11. The inlet end of the one-way valve 61 is connected to the exterior of the housing assembly 10, and the outlet end of the one-way valve 61 is located in the gas storage chamber 11. When the gas in the gas storage chamber 11 is depleted, gas is replenished into the gas storage chamber 11 through the one-way valve 61.

[0068] As shown in Figure 12, a control component installation cavity 17 and a pressure regulating valve installation cavity 18 are provided in the housing assembly 10. The pressure regulating valve installation cavity 18 is arranged between the air storage cavity 11 and the control component installation cavity 17, and the control component installation cavity 17 is arranged between the pressure regulating valve installation cavity 18 and the liquid storage cavity 12. The extension direction of the control component installation cavity 17 intersects with the extension direction of the first passage 15. The intersection can mean that the extension direction of the control component installation cavity 17 is perpendicular or non-perpendicular to the extension direction of the first passage 15.

[0069] As shown in Figure 12, the control component 20 includes a control member 21 and a second elastic member 22. The control member 21 is slidably arranged in the control member installation cavity 17, and at least part of the structure of the control member 21 extends outside the shell assembly 10. The two ends of the second elastic member 22 are respectively connected to the control member 21 and the cavity wall of the control member installation cavity 17. Specifically, the second elastic member 22 can be sleeved on the control member 21. Under the joint action of external force and the second elastic member 22, the control member 21 connects or disconnects the air outlet 32 ​​of the pressure regulating valve 30 and the atomization cavity 13.

[0070] Specifically, the control member 21 slides in the control member installation cavity 17 under the combined action of the external force and the second elastic member 22 to connect or disconnect the air outlet 32 ​​of the pressure regulating valve 30 and the atomization cavity 13 .

[0071] In one embodiment, as shown in Figures 12 and 13, the control member 21 includes a pressing portion 211, a limiting portion 212 and a sealing portion 213. The pressing portion 211 is arranged on the outside of the housing assembly 10, and the limiting portion 212 and the sealing portion 213 are both arranged in the control member installation cavity 17. The outer wall of the housing assembly 10 is provided with a mounting hole for mounting the control member 21. The outer diameter of the limiting portion 212 is larger than the aperture of the mounting hole to prevent the control member 21 from being separated from the control member installation cavity 17. The sealing portion 213 can connect or disconnect the air outlet 32 ​​and the atomization chamber 13 under the joint action of an external force and the second elastic member 22. When the user presses the control member 21 from the outside, the control member 21 slides inward, and the sealing portion 213 connects the air outlet 32 ​​and the atomization chamber 13, and the atomization device can automatically start to atomize. When the user lets go, the control member 21 can slide outward under the elastic restoring force of the second elastic member 22 , and the sealing portion 213 blocks the air outlet 32 ​​and the atomizing chamber 13 , and the atomizing device stops atomizing.

[0072] The control component 20 starts and stops the atomizing device through a purely mechanical mechanism. There is no need to use power to control the start and stop of the atomizing device, and the user does not need to worry about the power endurance problem. It is started by pressing and closed by the automatic rebound of the second elastic member 22. The method of starting and stopping the atomizing device of the control component 20 is simple and easy for users to operate.

[0073] The control component 20 is not limited to the above structure. For example, the control member 21 may slide in the control member installation cavity 17 with damping, without providing the second elastic member 22. The user can switch the state of the control component 20 by pulling out or pushing.

[0074] In one embodiment, as shown in Figures 14 and 15, the atomization device also includes a first baffle 70, and a plurality of first through holes 71 are provided on the first baffle 70. The first through holes 71 connect the atomization chamber 13 and the atomization outlet 14 on both sides of the first baffle 70. The diameter of the first through holes 71 can be designed to be 1μm-500μm according to the atomization requirements.

[0075] A guide portion 121 is protruding from the liquid storage chamber 12. A second airflow channel 1211 is provided within the guide portion 121, which is in communication with the air outlet 32. The first baffle 70 and the air outlet end of the second airflow channel 1211 are spaced apart and arranged opposite each other to form an atomization chamber 13 between the first baffle 70 and the air outlet end of the second airflow channel 1211. A drainage portion 91 is provided on the outer periphery of the guide portion 121. A second passage 16 is formed between the drainage portion 91 and the guide portion 121. The two ends of the second passage 16 respectively connect the liquid storage chamber 12 and the atomization chamber 13, so as to generate a negative pressure in the atomization chamber 13 when air flows through at high speed. The liquid matrix in the liquid storage chamber 12 can flow through the second passage 16 at high speed and impact the first baffle 70 due to the second pressure difference between the liquid storage chamber 12 and the atomization chamber 13 and capillary force to form an aerosol.

[0076] Furthermore, a second baffle 80 is provided on the side of the first baffle 70 away from the atomizing chamber 13. The second baffle 80 is provided with a second through hole 81 that penetrates the second baffle 80. The first through hole 71 and the second through hole 81 are staggered. The staggered setting refers to the staggered setting of the first through hole 71 and the second through hole 81 perpendicular to the airflow direction. The staggered setting can be that the first through hole 71 and the second through hole 81 are completely staggered or partially staggered. In one embodiment, a plurality of first through holes 71 can be evenly distributed in an annular shape along the edge of the first baffle 70, and the second through hole 81 is provided in the middle of the second baffle 80. By providing the second baffle 80, the second baffle 80 can not only block the un-atomized droplets ejected from the first through hole 71, but also play a certain blocking role on the aerosol, so as to reduce the impact force of the aerosol, making the atomization softer and easier for the user to absorb.

[0077] In one embodiment, as shown in Figures 14 and 15, the housing assembly 10 includes a detachably connected shell 50 and a nozzle 90. The detachable connection between the shell 50 and the nozzle 90 can be, for example, a snap-fit, a threaded connection, or an interference fit. The shell 50 and the nozzle 90 are connected by a threaded connection or an interference fit for better sealing. A liquid storage chamber 12 is provided in the shell 50. The nozzle 90 includes a protrusion 93 and a blocking portion 92 capable of blocking the liquid storage chamber 12. The protrusion 93 is provided on the end surface of the blocking portion 92 facing the liquid storage chamber 12. The nozzle 90 has a through-channel 94. The first baffle 70 is provided in the through-channel 94 to form a groove 95 and an atomization outlet 14 on both sides of the first baffle 70. At least part of the structure of the guide portion 121 is inserted into the groove 95. A second passage 16 is formed between the inner wall of the groove 95 and the outer wall of the guide portion 121.

[0078] By detachably connecting the shell 50 and the suction nozzle 90 and sealing the liquid storage chamber 12 with the suction nozzle 90, the user can remove the suction nozzle 90 from the shell 50 after using the substrate to be atomized in the liquid storage chamber 12, inject new substrate to be atomized into the liquid storage chamber 12, and then reinstall the suction nozzle 90, thereby achieving the replacement of the liquid in the liquid storage chamber 12; the user can also adjust the type of substrate to be atomized in the liquid storage tank according to needs, which makes it convenient for the user to experience the use effect of different atomized liquids and is simple to assemble.

[0079] In one embodiment, the first baffle 70 is disposed in the sealing portion 92, and an air pressure balance hole 96 is provided in the suction nozzle 90. One end of the air pressure balance hole 96 extends to the end surface of the sealing portion 92 facing the liquid storage chamber 12, and the other end extends to the atomization chamber 13 to connect the liquid storage chamber 12 and the atomization chamber 13. The air pressure balance hole 96 plays a role in balancing the negative pressure, ensuring that the matrix to be atomized in the liquid storage chamber 12 can smoothly enter the second passage 16.

[0080] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art can make several simple deductions, modifications or substitutions based on the concept of the present invention.
