[0032] The present application provides an electronic atomization device, which comprises an oil storage chamber, an atomization assembly, a sensor assembly, a gas extraction mechanism and an electronic control device. The atomization assembly is arranged in the oil storage chamber. The sensor assembly is connected to the oil storage chamber, and is configured to obtain first sensing information of the oil storage chamber, the first sensing information comprising first temperature information and / or second air pressure information. The gas extraction mechanism is in communication with the oil storage chamber. The electronic control device is electrically connected to the sensor assembly, and is configured to control the gas extraction mechanism to extract gas in the oil storage chamber according to the first sensing information.

[0033] In the electronic atomization device of the present application, when the temperature and / or air pressure in the oil storage chamber is equal to or greater than a preset threshold, the electronic control device controls the gas extraction mechanism to extract gas in the oil storage chamber, so that the air pressure in the oil storage chamber is reduced, and the atomization substrate in the oil storage chamber is less likely to leak.

[0034] The specific structure of the electronic atomization device will be described below.

[0035] Please refer to Figure 1 and Figure 2 The electronic atomization device 100 of the present application comprises an oil storage chamber 110, which stores an atomization substrate. The electronic atomization device 100 of the present application comprises an atomization assembly 111, which is arranged in the oil storage chamber 110 and can atomize the atomization substrate in the oil storage chamber 110. In the process of atomizing the atomization substrate into gas mist by the atomization assembly 111, the atomization chip of the atomization assembly 111 generates heat, the temperature of the oil storage chamber 110 rises, and because the volume of the gas mist is greater than that of the atomization substrate, the air pressure in the oil storage chamber 110 rises.

[0036] Please refer to Figure 1 The electronic atomization device 100 of the present application comprises a sensor assembly 120. The sensor assembly 120 is connected to the oil storage chamber 110, and is used to obtain first sensing information of the oil storage chamber 110. The sensor assembly 120 can comprise a temperature sensor and / or an air pressure sensor. The first sensing information can comprise first temperature information and / or first air pressure information.

[0037] Please refer to Figure 1 and Figure 2 The electronic atomization device 100 of the present application comprises a gas extraction mechanism 130, which is connected to the oil storage chamber 110. The electronic atomization device 100 of the present application comprises an electric control device 140, which is electrically connected to the sensor assembly 120. The electric control device 140 is used to control the gas extraction mechanism 130 to extract the gas in the oil storage chamber 110 according to the first sensing information. When the first temperature information and / or the first air pressure information is equal to or greater than a preset threshold value, the electric control device 140 controls the gas extraction mechanism 130 to extract the gas in the oil storage chamber 110 to reduce the air pressure in the oil storage chamber 110, so as to avoid the occurrence of leakage of the atomization substrate in the oil storage chamber 110.

[0038] Please refer to Figure 2 The gas extraction mechanism 130 can comprise a gas extraction chamber 131 and a moving piece 134. The gas extraction chamber 131 is connected to the oil storage chamber 110, and one end of the moving piece 134 is connected to the gas extraction chamber 131. The moving piece 134 can be driven to move by the electric control device 140 (to be described in detail later).

[0039] Please refer to Figure 2 The gas extraction chamber 131 comprises a chamber body part 132 and an adjusting piece 133. The chamber body part 132 is formed with an adjusting channel 135, and the adjusting piece 133 is sealingly sleeved with the adjusting channel 135. The adjusting piece 133 can be sleeved in the adjusting channel 135 (as shown in Figure 2 ), or can be sleeved outside the adjusting channel 135. One side of the adjusting piece 133, which is away from the chamber body part 132, is connected to the moving piece 134. The adjusting piece 133 and the moving piece 134 can be welded, adhered, clamped or screwed.

[0040] Please refer to Figure 2In some embodiments, the volume of the suction chamber 131 is variable. The adjusting member 133 can be relatively slid with the adjusting channel 135 so as to make the volume of the suction chamber 131 variable. It can be understood that when the adjusting member 133 slides towards the chamber body 132, the volume of the suction chamber 131 becomes smaller; when the adjusting member 133 slides away from the chamber body 132, the volume of the suction chamber 131 becomes larger. Alternatively, the adjusting member 133 can be a structure of elastic membrane, and the adjusting member 133 can be stretched in the axial direction of the adjusting channel 135 so as to make the volume of the suction chamber 131 variable. Similarly, when the adjusting member 133 bulges towards the chamber body 132, the volume of the suction chamber 131 becomes smaller; when the adjusting member 133 bulges away from the chamber body 132, the volume of the suction chamber 131 becomes larger.

[0041] The suction mechanism 130 has a suction state. When the suction mechanism 130 is in the suction state, the moving member 134 moves away from the suction chamber 131 under the drive of the electric control device 140, and the movement of the moving member 134 leads to the volume of the suction chamber 131 becoming larger. In this process, the adjusting member 133 moves along the axial direction of the adjusting channel 135 away from the chamber body 132 under the drive of the moving member 134 (i.e. the adjusting member 133 relatively slides with the adjusting channel 135), or the adjusting member 133 is stretched in the axial direction of the adjusting channel 135 under the drive of the moving member 134 (i.e. the adjusting member 133 is a structure of elastic membrane, and the adjusting member 133 elastically deforms).

[0042] In the electronic atomization device 100 of the present application, the electric control device 140 can drive the moving member 134 to move in various ways.

[0043] For example, the electric control device 140 can drive the moving member 134 to move by magnetic force. Specifically, the electric control device 140 comprises an electromagnet, and the moving member 134 can be provided with a magnet or can be made of ferromagnetic material. In response to the first sensing information being equal to or greater than the threshold value, the electromagnet is powered, the electromagnet and the moving member 134 generate mutual attractive magnetic force, and the moving member 134 moves towards the electric control device 140. It can be understood that in the above driving mode, the electric control device 140 and the moving member 134 do not need to be connected in contact. When the moving member 134 moves to the preset position, the electric control device 140 and the moving member 134 can be connected in contact or can be connected in air.

[0044] For another example, the electric control device 140 can drive the moving member 134 to move by screw nut drive. Briefly, the moving member 134 is connected to the movable side, and the moving member 134 moves under the cooperation of the nut and the screw rod. The cooperation of the nut and the screw rod can be in various ways, which can be referred to in the prior art and will not be described here.

[0045] In some embodiments, the air extraction mechanism 130 and the oil storage chamber 110 can be kept in a state of constant communication. The air pressure of the air extraction chamber 131 is equal to the air pressure of the oil storage chamber 110.

[0046] In other embodiments, the communication between the air extraction mechanism 130 and the oil storage chamber 110 can be closed. Please refer to Figure 2 The electronic atomization device 100 comprises a first one-way valve 150, which is arranged between the oil storage chamber 110 and the air extraction mechanism 130, and is used to allow gas to flow from the oil storage chamber 110 to the air extraction mechanism 130 and prevent gas from flowing from the air extraction mechanism 130 to the oil storage chamber 110. When the air extraction mechanism 130 is in the air extraction state, the first one-way valve 150 is opened, and the gas in the oil storage chamber 110 flows into the air extraction mechanism 130. When the air extraction mechanism 130 is in the non-air extraction state, the first one-way valve 150 is closed. Through the arrangement of the first one-way valve 150, the air pressure of the air extraction mechanism 130 and the air pressure of the oil storage chamber 110 can be controlled separately.

[0047] Please refer to Figure 2 The oil storage chamber 110 is provided with a pressure relief hole 112 that communicates with the air extraction mechanism 130, and the first one-way valve 150 covers one side of the pressure relief hole 112 close to the air extraction mechanism 130; when the air extraction mechanism 130 is in the air extraction state, the gas in the oil storage chamber 110 flows to the air extraction mechanism 130, and the first one-way valve 150 opens the pressure relief hole 112 due to the pushing of the gas.

[0048] Please refer to Figure 2 The first one-way valve 150 can be in the form of a cover, one end of the first one-way valve 150 can be hinged to the wall of the oil storage chamber 110, and the first one-way valve 150 can open or close the pressure relief hole 112 by rotating. Of course, the first one-way valve 150 can also be in the form of a plug, the plug rod of the first one-way valve 150 can be arranged in the pressure relief hole 112, and the plug cap of the first one-way valve 150 can cover the pressure relief hole 112. The first one-way valve 150 can move between the air extraction mechanism 130 and the oil storage chamber 110, and the plug cap of the first one-way valve 150 can open or close the pressure relief hole 112.

[0049] The part of the first one-way valve 150 facing the pressure relief hole 112 is connected with an oil-proof and air-permeable member. In this way, the atomization base of the oil storage chamber 110 can be prevented from flowing into the air extraction chamber 131 driven by the gas.

[0050] Please refer to Figure 2In some embodiments, the electronic atomization device 100 comprises a second one-way valve 160 arranged in the air extraction mechanism 130, which is configured to allow gas to flow from the air extraction mechanism 130 to the external environment and prevent gas from flowing from the external environment into the air extraction mechanism 130. By arranging the second one-way valve 160, the air extraction mechanism 130 can exhaust gas to the external environment, which facilitates the air extraction mechanism 130 to extract gas in the oil storage chamber 110 again.

[0051] The air extraction mechanism 130 can exhaust gas to the external environment by compressing the volume of the air extraction chamber 131. Specifically, the air extraction mechanism 130 has an exhaust state. When the air extraction mechanism 130 is in the exhaust state, the moving part 134 is driven by the electronic control device 140 to move towards the air extraction chamber 131, or the electronic atomization device 100 comprises a reset part connected to the air extraction chamber 131 (specifically, the chamber body part 132), which drives the moving part 134 to move towards the air extraction chamber 131. The movement of the moving part 134 causes the volume of the air extraction chamber 131 to decrease, and the gas in the air extraction chamber 131 flows to the external environment. The first one-way valve 150 is closed by the pushing of the gas, and the second one-way valve 160 is opened by the pushing of the gas. Both the first one-way valve 150 and the second one-way valve 160 are opened or closed by the pushing of the gas, and the opening or closing of the first one-way valve 150 and the second one-way valve 160 does not need to be achieved by an additional driving structure or manual operation. The arrangement of the first one-way valve 150 and the second one-way valve 160 is relatively ingenious.

[0052] As described above, the air extraction mechanism 130 can be driven by the electronic control device 140 to move towards the air extraction chamber 131. There are also various ways to achieve this, such as magnetic drive or screw nut drive. For details, please refer to the foregoing description, which will not be repeated here.

[0053] As described above, the air extraction mechanism 130 can be driven by the reset part to move towards the air extraction chamber 131. In some embodiments, the reset part can be a spring, and the two ends of the reset part are connected to the air extraction chamber 131 and the moving part 134, respectively. During the movement of the moving part 134 towards the air extraction chamber 131, the reset part is elongated. When the electronic control device 140 stops controlling the movement of the moving part 134, the reset part pulls the moving part 134 to reset. In other embodiments, the moving part 134 and the reset part are magnetically attracted to each other. The reset part can be a magnet, and the moving part 134 can be provided with a magnet or made of ferromagnetic material.

[0054] The reset part not only drives the moving part 134 to reset, but also provides an opposite force to the electronic control device 140 during the movement of the moving part 134 away from the chamber body part 132 driven by the electronic control device 140. The reset part buffers and partially offsets the force of the electronic control device 140, thereby making the movement of the moving part 134 more stable.

[0055] Referring to Figure 2 The electronic atomization device 100 includes a limiting member 170, and the two ends of the moving member 134 can be respectively abutted with the limiting member 170, and the limiting member 170 can guide and limit the movement of the moving member 134. In this way, the movement of the moving member 134 is good, and the position after the movement is controllable, and thus the volume of the air suction chamber 131 is controllable, and the air suction mechanism 130 has a good effect on the adjustment of the air pressure of the oil storage chamber 110.

[0056] Referring to Figure 1 In some embodiments, the air suction mechanism 130 includes an air suction chamber and a vacuum pump connected with each other, the air suction chamber is communicated with the oil storage chamber 110, and the vacuum pump is electrically connected with the electric control device 140. The air suction mechanism 130 has an air suction state, when the air suction mechanism 130 is in the air suction state, the vacuum pump is driven by the electric control device 140 to suck the air in the air suction chamber to the outside environment, and the gas in the oil storage chamber 110 flows to the air suction mechanism 130. The vacuum pump has various types, such as a gas ball type vacuum pump, a rotary vane type vacuum pump, a sliding valve type vacuum pump, a fixed plate type vacuum pump, a trochoidal type vacuum pump or a multi-chamber rotary vane type vacuum pump, and the like.

[0057] In some embodiments, after the suction time of the air suction mechanism 130 reaches the preset time (and / or the suction volume reaches the preset volume), the electric control device 140 stops controlling the air suction mechanism 130 to suck the gas in the oil storage chamber 110.

[0058] In some embodiments, the sensor assembly 120 is also used to obtain second sensing information of the outside environment, the second sensing information includes second temperature information and / or second air pressure information, and the electric control device 140 is used to control the air suction mechanism 130 to stop sucking the gas in the oil storage chamber 110 according to the first sensing information and the second sensing information. In this way, the electronic atomization device 100 adjusts the air pressure of the oil storage chamber 110 according to the change of the outside environment, so that the adjustment effect of the air pressure of the oil storage chamber 110 is better.

[0059] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made according to the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
