Description

Technical Field

[0001] The utility model relates to the technical field of atomization, and particularly relates to an atomization device with balanced air pressure. Background Art

[0002] Existing atomization devices generally include an atomization device, an oil supply bottle, a power supply device and a mouthpiece. An oil storage cavity is formed inside the atomization device, and an oil supply cavity is formed in the oil supply bottle. The oil supply cavity injects oil into the oil storage cavity through an oil supply port. The atomization device includes an atomization assembly installed in the oil storage cavity. The atomization assembly can adsorb the oil liquid in the oil storage cavity. The power supply device supplies power to the atomization assembly, so that the atomization assembly is heated. The atomization assembly converts the adsorbed oil liquid into aerosol, and the aerosol flows out through the mouthpiece of the atomization device for users to inhale.

[0003] However, during the process of injecting oil from the oil supply cavity into the oil storage cavity, the injection of e-liquid compresses the space occupied by the gas in the oil storage cavity, resulting in an increase in air pressure. At the same time, the reduction of e-liquid in the oil supply cavity causes the space occupied by the gas inside it to become larger and the air pressure to become lower. The air pressure in the two cavities is unbalanced, and the gas will automatically flow from the high-pressure oil storage cavity to the low-pressure oil supply cavity through the oil supply port. As the oil injection process continues, the air pressure imbalance intensifies, and the obstruction of the gas to the flow of e-liquid at the oil supply port increases, resulting in a relatively slow oil injection speed from the oil supply bottle to the atomization device or the oil injection stagnating. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an atomization device, aiming to solve the problems of unbalanced air pressure in the existing atomization device and poor oil injection effect from the oil supply bottle to the atomization device.

[0005] To achieve the above purpose, the utility model provides an atomization device with balanced air pressure, and the atomization device with balanced air pressure includes:

[0006] An atomization device, which forms an oil storage cavity, and the atomization device includes an atomization assembly installed in the oil storage cavity;

[0007] An oil supply bottle, which is connected to the atomization device. The oil supply bottle forms an oil supply cavity, and the oil supply bottle is provided with an oil supply port communicating with the oil supply cavity. The atomization device is provided with an oil inlet communicating with the oil storage cavity, and the oil supply port and the oil inlet are communicated with each other;

[0008] An isolation member, which is arranged at the oil inlet and the oil supply port and seals the oil inlet and the oil supply port. The isolation member is provided with an oil passing channel communicating with the oil supply port and the oil inlet;

[0009] A valve assembly, which is arranged at the oil passing channel and has two states of allowing and blocking the e-liquid to pass through the oil passing channel; and

[0010] An air duct connects the oil storage cavity and the oil supply cavity. One end of the air duct close to the oil supply cavity extends into the oil supply cavity and reaches the bottom of the oil supply cavity.

[0011] Optionally, the distance between the air duct and the bottom of the oil supply cavity is greater than or equal to 0.1 mm and less than or equal to 10 mm.

[0012] Optionally, the distance between the air duct and the bottom of the oil supply cavity is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0013] Optionally, the inner diameter of the air duct is greater than or equal to 1.5 mm and less than or equal to 10 mm.

[0014] Optionally, the inner diameter of the air duct is greater than or equal to 1.8 mm and less than or equal to 5 mm.

[0015] Optionally, the isolation member is provided with an air passage connecting the oil supply port and the oil inlet. The inner wall of the air passage is sleeved with the outer wall of the air duct.

[0016] Optionally, the isolation member is provided with an air passage connecting the oil supply port and the oil inlet. The wall of the air passage extends to form the air duct.

[0017] Optionally, the valve assembly is opened by the impact of the e-liquid flowing in the first direction and closed by the impact of the e-liquid flowing in the second direction opposite to the first direction. The first direction is the direction in which the e-liquid flows from the oil supply cavity towards the oil storage cavity.

[0018] Optionally, at least a part of the atomization device is located above the oil supply bottle.

[0019] In the atomizing device with pneumatic balance of the present utility model, the atomizing device includes an atomizing assembly, an oil supply bottle, a separator, a valve assembly, and an air duct; the atomizing assembly forms an oil storage cavity, and the atomizing assembly includes an atomizing component installed in the oil storage cavity; the oil supply bottle is connected to the atomizing device and forms an oil supply cavity, the oil supply bottle is provided with an oil supply port communicating with the oil supply cavity, the atomizing device is provided with an oil inlet communicating with the oil storage cavity, and the oil supply port and the oil inlet are communicated; the separator is arranged at the oil inlet and the oil supply port and seals the oil inlet and the oil supply port, and the separator is penetrated with an oil passage communicating the oil supply port and the oil inlet; the valve assembly is arranged at the oil passage and has two states of allowing and blocking the e-liquid to pass through the oil passage; the air duct communicates the oil storage cavity and the oil supply cavity, and one end of the air duct close to the oil supply cavity extends into the oil supply cavity and extends to the bottom of the oil supply cavity. Thus, when the user injects e-liquid into the atomizing device through the oil supply bottle, the orientation of the atomizing device is adjusted so that one end of the air duct extending into the oil supply cavity can leak out from the e-liquid, the valve assembly is opened, and the e-liquid in the oil supply cavity flows to the oil storage cavity through the oil passage. The injection of e-liquid causes the air pressure in the oil storage cavity to rise and the air pressure in the oil supply cavity to drop; because gas automatically flows from high pressure to low pressure, and the density of gas is less than that of e-liquid, the gas in the oil storage cavity can flow upward through the air duct. The air duct guides the flow of gas. Also, because one end of the air duct extending into the oil supply cavity leaks out from the e-liquid and contacts the gas in the oil supply cavity, the gas in the air duct can be quickly discharged into the oil supply cavity. Thus, the air pressures in the oil storage cavity and the oil supply cavity are relatively balanced, and the e-liquid flows from the oil supply cavity to the oil storage cavity through the valve assembly smoothly. Therefore, the effect of injecting e-liquid from the oil supply bottle into the atomizing device is relatively good. Brief Description of the Drawings

[0031] The present utility model provides an atomization device with air pressure balance. The atomization device may include an atomization assembly, an oil supply bottle, a separator, a valve assembly, and an air duct. The atomization assembly may form an oil storage cavity, and the atomization assembly may include an atomization component installed in the oil storage cavity. The oil supply bottle may be connected to the atomization assembly and form an oil supply cavity. The oil supply bottle may be provided with an oil supply port communicating with the oil supply cavity, and the atomization assembly may be provided with an oil inlet communicating with the oil storage cavity. The oil supply port and the oil inlet may be communicated with each other. The separator may be disposed at the oil inlet and the oil supply port and seal the oil inlet and the oil supply port. The separator may be provided with an oil passage communicating with the oil supply port and the oil inlet. The valve assembly may be disposed at the oil passage and may have two states of allowing and blocking the e-liquid to pass through the oil passage. The air duct may communicate the oil storage cavity and the oil supply cavity. One end of the air duct close to the oil supply cavity may extend into the oil supply cavity and extend to the bottom of the oil supply cavity.

[0032] The specific structure of the atomization device with air pressure balance will be mainly described below.

[0033] Please refer to Figures 1 to 4 , the atomization device 110 of the atomization device with air pressure balance provided by the present utility model may include an atomization assembly 110. The atomization assembly 110 may form an oil storage cavity 111, and the oil storage cavity 111 may store e-liquid. The atomization assembly 110 may include an atomization component 112, and the atomization component 112 may be installed in the oil storage cavity 111. The e-liquid in the oil storage cavity 111 can flow to the atomization component 112, and the atomization component 112 can atomize the e-liquid.

[0034] Please refer to Figures 1 to 4 , the atomization device with air pressure balance 100 of the present utility model may further include an oil supply bottle 120. The oil supply bottle 120 may form an oil supply cavity 121, and the oil supply cavity 121 may be used to store e-liquid. The oil supply bottle 120 may be provided with an oil supply port 122, and the oil supply port 122 may communicate with the oil supply cavity 121. Thus, the e-liquid in the oil supply cavity 121 can flow out through the oil supply port 122. Of course, the e-liquid in the oil supply cavity 121 can also be injected through the oil supply port 122. Alternatively, the oil supply bottle 120 may be provided with a refueling port (not shown) communicating with the oil supply cavity 121.

[0035] Please refer to Figures 1 to 4 , the oil supply bottle 120 may be connected to the atomization assembly 110. The cavity wall of the oil supply cavity 121 and the cavity wall of the oil storage cavity 111 may be integrally formed, so that the connection between the oil supply bottle 120 and the atomization assembly 110 is relatively tight. Of course, the cavity wall of the oil supply cavity 121 and the cavity wall of the oil storage cavity 111 may also be detachably connected, for example, by clamping, plugging, screwing, bonding and other connection methods, so as to facilitate the replacement of the old and new oil supply bottles 120.

[0036] Please refer to Figures 1 to 4, the atomizing device 110 may be provided with an oil inlet 113 communicating with the oil storage chamber 111, and the oil supply port 122 and the oil inlet 113 may be in communication. In this way, the e-liquid can flow between the oil supply chamber 121 and the oil storage chamber 111 via the oil inlet 113 and the oil supply port 122.

[0037] Please refer to Figures 1 to 4 , the atomizing device 100 with balanced air pressure may further include a separator 150. The separator 150 may be disposed at the oil inlet 113 and the oil supply port 122 to seal the oil inlet 113 and the oil supply port 122. The separator 150 may be provided with an oil passage 151 communicating the oil supply port 122 and the oil inlet 113.

[0038] Please refer to Figures 1 to 4 , the atomizing device 100 with balanced air pressure may further include a valve assembly 130. The valve assembly 130 may be disposed at the oil passage 151. The valve assembly 130 may have two states of allowing and blocking the e-liquid to pass through the oil passage 151. Specifically, when the valve assembly 130 opens the oil passage 151, the e-liquid can flow between the oil supply chamber 121 and the oil storage chamber 111 via the oil passage 151; when the valve assembly 130 closes the oil passage 151, the valve assembly 130 blocks the flow of the e-liquid between the oil supply chamber 121 and the oil storage chamber 111.

[0039] The opening and closing of the valve assembly 130 can be manual. Specifically, the valve assembly 130 can be components such as a baffle (block), a piston, a screw, etc., and can be controlled to open and close by manual movement, rotation, etc.

[0040] The opening and closing of the valve assembly 130 can also be automatic. Please refer to Figures 1 to 4 , in some embodiments, the valve assembly 130 may be a one-way valve assembly 130. Specifically, the one-way valve assembly 130 can be opened by the impact of the e-liquid flowing in the first direction and can be closed by the impact of the e-liquid flowing in the second direction opposite to the first direction. The first direction can be the direction in which the e-liquid flows from the oil supply chamber 121 towards the oil storage chamber 111. In other words, the one-way valve assembly 130 only allows the e-liquid to flow from the oil supply chamber 121 to the oil storage chamber 111. Thus, the e-liquid in the oil storage chamber 111 will not flow back to the oil supply chamber 121, which can ensure that there is an appropriate amount of e-liquid in the oil storage chamber 111, thereby having a better atomizing effect. The above flow of the e-liquid can be only affected by gravity or can be driven by other forces, without limitation.

[0041] The valve assembly 130 can be a ball check valve (as shown in Figure 1 and Figure 4 ), a spring check valve (as shown in Figure 2 ), or a swing check valve (as shown in Figure 3 ), or at least one of them.

[0042] For details, please refer to Figure 1 and Figure 4 , the ball check valve 130 generally includes a valve ball 131 and a limiting member 132. The valve ball 131 can close the oil passage 151 by its own gravity. The limiting member 132 is generally installed in the oil storage cavity 111 to limit the movement of the valve ball 131. When the user adjusts the atomizing device 100 to the open position (such as tilting or inverted as Figure 4 shown), the e-liquid in the oil supply cavity 121 flows towards the valve ball 131 due to gravity. The valve ball 131 is simultaneously impacted by the e-liquid in the oil supply cavity 121 and the earth's gravitational force, causing displacement. Then it is limited by the limiting member 132, and the oil passage 151 is opened. The e-liquid flows through the oil passage 151 to the oil storage cavity 111; when the user adjusts the atomizing device 100 to the closed position (such as upright as Figure 1 shown), the e-liquid in the oil storage cavity 111 flows towards the oil supply cavity 121. The valve ball 131 resets under the action of the impact of the e-liquid and the earth's gravitational force, thus closing the oil passage 151 and blocking the flow of e-liquid from the oil storage cavity 111 to the oil supply cavity 121.

[0043] Please refer to Figure 2 , the spring check valve 130 generally includes a valve flap 133 and a spring 134 connected to each other. The valve flap 133 can be arranged at the oil passage 151 to open or close the oil passage 151. One end of the spring 134 away from the valve flap 133 can be connected to the cavity wall of the oil supply cavity 121. When the user adjusts the atomizing device 100 to the open position (tilting or inverted), the valve flap 133 is simultaneously impacted by the e-liquid in the oil supply cavity 121 and the earth's gravitational force, causing displacement. The spring 134 is stretched by the valve flap 133 to limit the further movement of the valve flap 133, and the oil passage 151 is opened. The e-liquid flows through the oil passage 151 to the oil storage cavity 111; when the user adjusts the atomizing device 100 to the closed position (such as upright as Figure 2 shown), the e-liquid in the oil storage cavity 111 flows towards the oil supply cavity 121. The valve flap 133 is subject to the earth's gravitational force, the impact of the e-liquid and the pulling force of the spring 134, and resets to close the oil passage 151, blocking the backflow of the e-liquid.

[0044] Please refer to Figure 3 , the swing check valve 130 generally includes a hinge member 135 and a swing valve flap 136 rotatably connected to the hinge member 135. The swing valve flap 136 can rotate circumferentially along the hinge member 135 to open and close the oil passage 151. The hinge member 135 can limit the rotation angle of the swing valve flap 136. The specific opening and closing processes are similar to those of the above two check valves and will not be elaborated here.

[0045] Please refer to Figures 1 to 4, the atomizing device 100 with pneumatic balance of the present utility model may further include an air duct 140, and the air duct 140 can communicate the oil storage chamber 111 and the oil supply chamber 121. The air duct 140 can connect the atomizing device 110 and the oil supply bottle 120 from the outside of the atomizing device 110 and the oil supply bottle 120. Specifically, one end of the air duct 140 can be connected to the chamber wall of the oil storage chamber 111, and the other end can be connected to the chamber wall of the oil supply chamber 121. The air duct 140 can also communicate the oil storage chamber 111 and the oil supply chamber 121 by connecting an isolation member 150 (detailed later). No specific limitation is imposed on the shape of the air duct 140. The cross-section of the air duct 140 can be triangular, circular, square, polygonal, waist-shaped or irregular, etc. The inner diameter of the air duct 140 can be unified as a whole, or different parts can have different inner diameters. The material of the air duct 140 can be metal, plastic or wood, etc. As long as the material does not have an obvious adverse effect on the e-liquid and its atomization, it is within the protection scope of the present utility model.

[0046] Please refer to Figures 1 to 4 , one end of the air duct 140 close to the oil supply chamber 121 can extend into the oil supply chamber 121, and the air duct 140 can extend to the bottom of the oil supply chamber 121. With such a setting, when the user injects oil into the atomizing device 110 through the oil supply bottle 120, the orientation of the atomizing device 100 is adjusted so that the end of the air duct 140 extending into the oil supply chamber 121 can leak out from the e-liquid. The valve assembly 130 is opened, and the e-liquid in the oil supply chamber 121 flows to the oil storage chamber 111. The injection of the e-liquid causes the space occupied by the gas in the oil storage chamber 111 to be compressed, and the air pressure increases. At the same time, the reduction of the e-liquid causes the space occupied by the gas in the oil supply chamber 121 to become larger, and the air pressure becomes lower. Because the gas automatically flows from high pressure to low pressure, and the density of the gas is less than the density of the e-liquid, the gas in the oil storage chamber 111 can flow upward through the air duct 140. The air duct 140 guides the flow of the gas. Also, because the end of the air duct 140 extending into the oil supply chamber 121 leaks out from the e-liquid and contacts the gas in the oil supply chamber 121, the gas in the air duct 140 can be quickly discharged into the oil supply chamber 121. Thus, the air pressures of the oil storage chamber 111 and the oil supply chamber 121 are relatively balanced, and the e-liquid flows from the oil supply chamber 121 to the oil storage chamber 111 through the valve assembly 130 smoothly, and the effect of injecting oil from the oil supply bottle 120 into the atomizing device 110 is better. In addition, when the user inhales the aerosol, the atomizing device 100 is generally placed upright, and the end of the air duct 140 extending into the oil supply chamber 121 is located in the e-liquid, with the e-liquid sealing. The gas in the oil supply chamber 121 cannot enter the oil storage chamber 111, and it is not easy to produce inhalation noise when the user inhales, and the use experience is good.

[0047] The distance between the air duct 140 and the bottom of the oil supply chamber 121 can be greater than 0.1 mm and less than or equal to 10 mm. If the distance between the air duct 140 and the bottom of the oil supply chamber 121 is less than 0.1 mm, the distance is too close, the gas outflow speed is slow, and the pressure relief effect is poor. If the distance between the air duct 140 and the bottom of the oil supply chamber 121 is greater than 10 mm, when there is not much remaining e-liquid in the oil supply chamber 121, the lower end of the air duct 140 is no longer immersed in the e-liquid, the gas in the oil supply chamber 121 is no longer sealed by the e-liquid, and when the user sucks, it is easy to cause the gas in the oil supply chamber 121 to be sucked into the atomization component 112 through the air duct 140 and the valve component 130 (if the valve component 130 can be pushed open by the gas), generating a sucking noise and affecting the use experience. Further, the distance between the air duct 140 and the bottom of the oil supply chamber 121 can be 0.5 - 5 mm, 0.3 - 8 mm, 0.7 - 5 mm, 0.9 - 2 mm, 2 - 3 mm, 0.7 - 7 mm, 0.5 - 1 mm or 0.5 - 1 mm, etc., not limited thereto. Further still, the distance between the air duct 140 and the bottom of the oil supply chamber 121 can be 0.1 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc.

[0048] The inner diameter of the air duct 140 can be greater than or equal to 1.5 mm and less than or equal to 10 mm. When the inner diameter of the air duct 140 is less than 1.5 mm, the exhaust effect is relatively poor. When the inner diameter of the air duct 140 is greater than 10 mm, the occupied space of the air duct 140 is relatively large, and it is also easy to cause the e-liquid to flow back through the air duct 140. Further, the inner diameter of the air duct 140 can be 1.7 - 2 mm, 1.8 - 5 mm, 1.8 - 8 mm, 2 - 5 mm, 1.9 - 2 mm, 2 - 3 mm, 1.9 - 7 mm, 5 - 10 mm or 1.8 - 2 mm, etc., not limited thereto. Further still, the inner diameter of the air duct 140 can be 1.5 mm, 1.7 mm, 1.8 mm, 1.85 mm, 1.9 mm, 1.95 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm or 10 mm, etc.

[0049] Please refer to Figure 1 and Figure 2, the separator 150 may also be provided with an air passage 152 communicating the fuel supply port 122 and the fuel inlet 113, and the inner wall of the air passage 152 may be sleeved with the outer wall of the air duct 140. In this way, the air duct 140 can be arranged inside the atomizing device 110 and the fuel supply bottle 120, making the overall structure of the atomizing device 100 more compact. At the same time, this also shortens the path of gas discharge, improves the gas discharge efficiency, and has a better air pressure balance effect. The sleeving of the air passage 152 and the air duct 140 can be achieved by bonding, screwing, interference fit or other methods, without specific limitation. To ensure an ideal connection effect, as Figure 1 , Figure 2 and Figure 4 shown, the air passage 152 may extend in the length direction of the air duct 140, which can increase the contact area between the air passage 152 and the air duct 140 and enhance the connection strength.

[0050] Please refer to Figure 3 , the channel wall of the air passage 152 may extend to form the above-mentioned air duct 140. In this way, there is no need to additionally set up a structure to realize the exhaust of the oil storage cavity 111 to the fuel supply cavity 121, making the assembly of the atomizing device 100 more convenient.

[0051] The atomizing device 110 and the fuel supply bottle 120 may be arranged vertically (please refer to Figure 1 , Figure 2 and Figure 4 ), or horizontally (please refer to Figure 3 ), both of which can achieve the effect of exhausting and relieving pressure in the oil storage cavity 111 through the air duct 140. In some preferred embodiments, the atomizing device 110 may be at least partially located above the fuel supply bottle 120. Specifically, please refer to Figure 4 , when the atomizing device 100 is inverted, the valve ball 131 moves downward under the impact of the e-liquid in the fuel supply cavity 121 and the earth's gravity. The movement of the valve ball 131 is limited by the limiting member 132. The e-liquid in the fuel supply cavity 121 flows into the oil storage cavity 111, and the gas in the oil storage cavity 111 flows upward through the air duct 140. Also, since the end of the air duct 140 extending into the fuel supply cavity 121 leaks out of the e-liquid and contacts the gas in the fuel supply cavity 121, the gas in the air duct 140 can be quickly discharged into the fuel supply cavity 121. Thus, the air pressure in the oil storage cavity 111 and the fuel supply cavity 121 is relatively balanced, and the e-liquid flows through the valve assembly 130 to the oil storage cavity 111 smoothly. Please refer to Figures 1 to 3 , when the atomizing device 100 is upright, the valve assembly 130 is closed, and the end of the air duct 140 extending into the fuel supply cavity 121 is located in the e-liquid, with the e-liquid sealing it. The gas in the fuel supply cavity 121 cannot enter the oil storage cavity 111, and it is not easy to generate a suction noise when the user sucks, providing a better user experience.

[0052] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
