Description

Technical Field

[0001] The present application relates to the technical field of electronic smoking devices, and in particular to an electronic atomization device. Background Art

[0002] At present, there are many disposable electronic cigarette products on the market. Most disposable electronic cigarettes use oil storage cotton to store e-liquid. However, the oil storage rate of oil storage cotton is often only 70%~80%. The oil storage cotton will take up a large space, resulting in the overall size of the electronic cigarette product being relatively large. In addition, the oil storage cotton itself will absorb part of the e-liquid, which cannot be heated and atomized, resulting in a low utilization rate of the e-liquid. Since the physical structure of the oil storage cotton is vertical fibers, it will filter the flavor sugars in the e-liquid, affecting the restoration of the e-liquid taste. In addition, the oil storage cotton conducts oil through contact with the oil absorption cotton in the heating module, and the oil conduction rate is low. During rapid or long-term puffing, the user may experience poor oil supply due to the low oil conduction rate, resulting in a sticky core, which seriously affects the user's puffing taste.

[0003] Therefore, there are many disposable electronic cigarettes with visible oil tanks on the market. The oil is directly stored in the oil tank, but the oil tank is only sealed with a silicone plug. The electronic cigarette is prone to oil leakage during transportation, carrying, and use. Especially when the electronic cigarette is transported under high negative pressure, the long-term high negative pressure is more likely to cause oil leakage. In addition, the heating wire (usually made of iron-chromium-aluminum alloy) is prone to rust when immersed in the oil for a long time, and the heating wire is prone to discoloration of the oil when immersed in the oil for a long time, which seriously affects the user's smoking taste and brings a bad user experience.

[0033] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0034] 1 to 3 , the present application provides an electronic atomization device 100 , which includes an atomizer 110 and an oil supply assembly 120 , and is used to heat and atomize an atomization matrix to generate an aerosol for a user to inhale. In this embodiment, the atomization matrix is ​​tobacco oil.

[0035] The atomizer 110 includes a liquid storage tank 111 and an atomizing assembly 112. The liquid storage tank 111 can be used to receive and store atomized matrix. The atomizing assembly 112 is disposed in the liquid storage tank 111. The atomizing assembly 112 is used to heat the atomized matrix received in the liquid storage tank 111 to generate an atomized matrix.

[0036] The oil supply assembly 120 includes a driving pump 121 and an oil bottle 122. The oil bottle 122 is used to store the atomized matrix. The oil bottle 122 is connected to the liquid storage tank 111 through the oil inlet pipe 123 and the exhaust pipe 130. The driving pump 121 is used to extract the atomized matrix in the oil bottle 122 to the liquid storage tank 111. Exemplarily, one end of the oil inlet pipe 123 is inserted in the liquid storage tank 111, and the other end of the oil inlet pipe 123 is inserted in the oil bottle 122. The driving pump 121 extracts the atomized matrix in the oil bottle 122 into the liquid storage tank 111 through the oil inlet pipe 123, so as to supply the atomized matrix in the oil bottle 122 to the liquid storage tank 111 for the atomization assembly 112 to heat and atomize to generate aerosol for the user to inhale. When the oil bottle 122 is pouring the atomized matrix into the liquid storage tank 111, the atomized matrix will squeeze the gas in the liquid storage tank 111. If the gas pressure in the liquid storage tank 111 is not reduced, the atomized matrix in the liquid storage tank 111 will flow back into the oil bottle 122 under the action of the gas pressure, and the atomized matrix in the oil bottle 122 cannot be smoothly supplied to the liquid storage tank 111. In the present embodiment, one end of the exhaust pipe 130 is inserted in the liquid storage tank 111, and the other end of the exhaust pipe 130 is inserted in the oil bottle 122. In the process of the atomized matrix entering the liquid storage tank 111 from the oil bottle 122, the gas in the liquid storage tank 111 can enter the oil bottle 122 through the exhaust pipe 130 to maintain the pressure difference balance between the liquid storage tank 111 and the oil bottle 122, so that the atomized matrix in the oil bottle 122 can be smoothly supplied to the liquid storage tank 111.

[0037] The above-mentioned electronic atomization device 100 stores the atomization matrix independently in the oil bottle 122, which can avoid the adverse phenomenon of leakage of the atomization matrix in the liquid storage tank 111. Even if the electronic atomization device 100 is transported under high negative pressure, there will be no problem of leakage of the atomization matrix. The atomization component 112 will not be immersed in the atomization matrix for a long time, avoiding the atomization component 112 from being corroded by the atomization matrix, and preventing the atomization matrix from deteriorating and other adverse phenomena, so as to ensure the inhalation taste of the aerosol generated by heating and atomizing the atomization matrix, thereby improving the user's inhalation experience.

[0038] In one embodiment, referring to FIGS. 1 to 3 , the oil supply assembly 120 further includes an oil extraction pipe 124. One end of the oil extraction pipe 124 extends into the bottom of the oil bottle 122, and the other end of the oil extraction pipe 124 is connected to the driving pump 121, one end of the oil inlet pipe 123 extends into the liquid storage tank 111, and the other end of the oil inlet pipe 123 is connected to the driving pump 121. Exemplarily, the oil bottle 122 is provided with a first oil outlet, the driving pump 121 is provided with a first oil inlet and a second oil outlet, the liquid storage tank 111 has a second oil inlet, one end of the oil extraction pipe 124 extends into the bottom of the oil bottle 122 through the first oil outlet, the other end of the oil extraction pipe 124 is connected to the driving pump 121 through the first oil inlet, one end of the oil inlet pipe 123 is connected to the driving pump 121 through the second oil outlet, and the other end of the oil inlet pipe 123 extends into the liquid storage tank 111 through the second oil inlet. The driving pump 121 can extract the atomized matrix in the oil bottle 122 through the oil extraction pipe 124, and further supply the atomized matrix to the liquid storage tank 111 through the oil inlet pipe 123. In addition, the oil extraction pipe 124 extends to the bottom of the oil bottle 122, and can extract the atomized matrix in the oil bottle 122 to the maximum extent and supply it to the liquid storage tank 111, so as to make full use of the atomized matrix stored in the oil bottle 122.

[0039] Further, referring to Figures 1 to 3, one end of the exhaust pipe 130 extends into the liquid storage tank 111, and the other end of the exhaust pipe 130 extends into the oil bottle 122. If the oil bottle 122 is provided with an air inlet and the liquid storage tank 111 has an air outlet, one end of the exhaust pipe 130 extends into the liquid storage tank 111 through the air outlet, and the other end of the exhaust pipe 130 extends into the oil bottle 122 through the air inlet. Since the atomized matrix poured into the liquid storage tank 111 will cause the gas to gather on one side close to the top of the liquid storage tank 111, in the present embodiment, the end of the exhaust pipe 130 extending into the liquid storage tank 111 is higher than the liquid level of the atomized matrix received in the liquid storage tank 111. On the one hand, the gas inside the liquid storage tank 111 can enter the oil bottle 122 through the exhaust pipe 130 during the extrusion process, thereby ensuring the pressure difference balance between the liquid storage tank 111 and the oil bottle 122. On the other hand, the atomized matrix entering the liquid storage tank 111 can be prevented from flowing back into the exhaust pipe 130, thereby ensuring the smoothness of the exhaust pipe 130 in guiding and discharging the gas in the liquid storage tank 111.

[0040] In one embodiment, referring to FIGS. 2 to 4 , the atomization assembly 112 includes an atomization tube 1121 and a heating module 1122, the heating module 1122 is disposed in the atomization tube 1121, and the heating module 1122 is used to draw and heat the atomization matrix in the liquid storage tank 111. In this embodiment, the heating module 1122 includes an oil-guiding cotton 1123 and a heating element 1124, the heating element 1124 is disposed on the oil-guiding cotton 1123, the atomization tube 1121 is disposed in the liquid storage tank 111, and the atomization tube 1121 is provided with an oil inlet hole penetrating its side wall, so that the atomization matrix received in the liquid storage tank 111 can flow to the inside of the atomization tube 1121 through the oil inlet hole, the oil-guiding cotton 1123 draws the atomization matrix flowing to the inside of the atomization tube 1121, and the atomization matrix drawn by the oil-guiding cotton 1123 is heated and atomized by the heating element 1124 to generate an aerosol for the user to inhale. A first sealing seat 140 is provided at the gap between the heating module 1122 and the atomizing tube 1121 . The first sealing seat 140 can seal the atomized matrix flowing into the atomizing tube 1121 to prevent the atomized matrix inside the atomizing tube 1121 from leaking to other structures.

[0041] The oil-conducting cotton 1123 may be a mixed fabric of flax, non-woven fabric and wood pulp cotton, so that the oil-conducting cotton 1123 has excellent oil absorption and oil attachment properties; the heating element 1124 may be a heating wire or a heating net. For example, when the heating element 1124 is a heating wire, the heating element 1124 may be arranged on the oil-conducting cotton 1123 by winding, and when the heating element 1124 is a heating net, the heating element 1124 may be arranged on the oil-conducting cotton 1123 by inserting. The first sealing seat 140 is integrally formed by a flexible material such as plastic and silicone, so that the first sealing seat 140 after forming is flexible and can seal the gap between the heating module 1122 and the atomizing tube 1121 to prevent the atomizing matrix inside the atomizing tube 1121 from leaking to other structures.

[0042] Further, referring to FIGS. 2 to 4 , the atomizing assembly 112 also includes an oil cup 1126 and a second sealing seat 1127. The oil cup 1126 has an open end and a liquid storage bin 111, such as the side wall and the bottom wall of the oil cup 1126 are arranged to form the liquid storage bin 111, and the top of the oil cup 1126 has an open end, and the open end is connected to the liquid storage bin 1126, so that the atomized matrix in the liquid storage bin 111 can be cleaned through the open end, so as to avoid the atomized matrix in the liquid storage bin 111 from deteriorating during a long period of precipitation. The second sealing seat 1127 is sealed at the open end of the oil cup 1126 to seal the atomized matrix in the liquid storage bin 111, so as to avoid the atomized matrix in the liquid storage bin 111 from leaking. The atomizer tube 1121 is inserted into the oil cup 1126 to realize the setting of the atomizer tube 1121 in the liquid storage tank 111, and a third sealing seat 150 is provided at the gap between the atomizer tube 1121 and the oil cup 1126. The third sealing seat 150 seals the gap at the connection between the atomizer tube 1121 and the oil cup 1126 to prevent the atomized matrix received in the liquid storage tank 111 from flowing out to other structures through the gap between the atomizer tube 1121 and the oil cup 1126.

[0043] The second sealing seat 1127 and the third sealing seat 150 are integrally formed by flexible materials such as plastic and silicone, so that the second sealing seat 1127 and the third sealing seat 150 are flexible after forming, and can prevent the leakage of the atomized matrix.

[0044] In one embodiment, referring to FIG. 2 to FIG. 4 , the electronic atomization device 100 further includes a control component 160, which is electrically connected to the drive pump 121 and the heating module 1122. When the user performs a suction action, the control component 160 sends a signal and controls the drive pump 121 to work, and the atomized matrix in the oil bottle 122 is extracted into the liquid storage tank 111 through the drive pump 121. At the same time, the control component 160 controls the heating module 1122 to heat and atomize the atomized matrix received in the liquid storage tank 111 to generate an aerosol for the user to inhale.

[0045] Specifically, referring to FIGS. 2-4 , the control assembly 160 includes a control board 161 and a power supply 162 . The control board 161 is electrically connected to the power supply 162 and the driving pump 121 . The power supply 162 is electrically connected to the heating module 1122 . Exemplarily, the control board 161 includes components such as a microphone and a microcontroller unit (MCU). The heating element 1124 in the heating module 1122 has a pin 1125, and the pin 1125 extends to the outside through the oil cup 1126 to be electrically connected to the power supply element 162. For example, a threading hole is provided at the bottom of the oil cup 1126, and the pin 1125 extends to the outside of the oil cup 1126 through the threading hole. A sealant is provided at the gap between the pin 1125 and the threading hole to seal the atomized matrix received in the liquid storage tank 111, so as to prevent the atomized matrix received in the liquid storage tank 111 from leaking at the gap between the pin 1125 and the threading hole, and to prevent the liquid storage tank 111 from leaking due to negative pressure.

[0046] In the electronic atomization device 100, when the user performs a puffing action, the microphone starts after sensing the change in air pressure, and the microcontroller unit accurately calculates the number of puffs N, the puffing time T for each puff, and the laboratory test TPM (Total Particulate Matter). The atomization substrate consumption V is equal to the product of the number of puffs N, the puffing time T for each puff, and the laboratory test TPM value, that is, V=N×T×TPM. The microcontroller unit can determine the atomization substrate consumption of the liquid storage tank 111 based on this, and accurately control the action of the driving pump 121 to accurately control the mass of the atomization substrate extracted from the oil bottle 122 into the liquid storage tank 111, that is, to supply the atomization substrate to the liquid storage tank 111 on demand, to ensure that there is sufficient atomization substrate in the liquid storage tank 111, and to prevent the atomization component 112 from dry burning. At the same time, when there is an atomization matrix in the liquid storage tank 111, the oil-conducting cotton 1123 absorbs the atomization matrix in the liquid storage tank 111 and attaches the atomization matrix to its surface. When the user performs an inhalation action, the control board 161 controls the power supply component 162 to supply power to the heating component 1124 through the pin 1125. The heating component 1124 generates heat and heats the atomization matrix attached to the surface of the oil-conducting cotton 1123 to atomize and generate an aerosol. Among them, it should be noted that the driving pump 121 can move in an intermittent driving manner, that is, when the oil bottle 122 supplies the atomizing matrix in the liquid storage tank 111 to be sufficient for the atomization operation, the driving pump 121 does not work, thereby reducing the power consumption of the electronic atomization device 100 and extending the use time of the electronic atomization device 100; and after the atomizing matrix in the liquid storage tank 111 is consumed too much, the control board 161 will re-control the driving pump 121 to work, so as to re-extract the atomizing matrix in the oil bottle 122 into the liquid storage tank 111, to ensure that there is a sufficient supply of atomizing matrix in the liquid storage tank 111, and to avoid the undesirable phenomenon of dry burning of the atomization component 112.

[0047] Further, referring to Figures 1-3, the drive pump 121 is a micro pump. The drive pump 121 is selected as a micro pump to reduce the volume occupied by the drive pump 121 in the electronic atomization device 100. While ensuring that the drive pump 121 can perform the oil pumping operation from the oil bottle 122 toward the liquid storage tank 111, the overall volume of the electronic atomization device 100 is reduced.

[0048] In one embodiment, referring to FIG. 2 , FIG. 3 and FIG. 5 , the oil bottle 122 includes a bottle body 1221 and a cover body 1222. The bottle body 1221 has an open end 1223 and a liquid storage cavity 1224. The side wall and the bottom wall of the oil bottle 122 are arranged to form the liquid storage cavity 1224. The liquid storage cavity 1224 is used to store the atomized matrix, and the open end 1223 is connected to the liquid storage cavity 1224. The cover body 1222 is detachably sealed at the open end of the bottle body 1221. On the one hand, the cover body 1222 can seal the atomized matrix stored in the liquid storage cavity 1224. On the other hand, when the atomized matrix in the liquid storage cavity 1224 is insufficient, the atomized matrix in the liquid storage cavity 1224 can be supplemented by removing the cover body 1222 from the bottle body 1221. Preferably, a sealing structure such as a sealing ring or a sealing gasket is provided on the cover body 1222, so that when the cover body 1222 is sealed on the open end 1223 of the bottle body 1221, the cover body 1222 can seal the liquid storage cavity 1224 through the sealing structure to prevent the atomized matrix stored in the liquid storage cavity 1224 from leaking.

[0049] In one embodiment, referring to FIGS. 1 to 3 , the electronic atomization device 100 further includes a first shell 170, a second shell 180 and a connector 190. The first shell 170 and the second shell 180 are connected as a whole through the connector 190. For example, the connector 190 is provided with a screw connection portion, and the first shell 170 and the second shell 180 are connected together by screw connection, so that the first shell 170 and the second shell 180 are connected as a whole. When the first shell 170 and the second shell 180 are connected, the first shell 170 and the second shell 180 are covered on the outside of the atomizer 110 and the oil supply assembly 120. The first shell 170 and the second shell 180 serve as the appearance of the electronic atomization device 100, and protect the internal structural parts of the electronic atomization device 100 (such as the atomizer 110 and the oil supply assembly 120). Preferably, the first shell 170 and the second shell 180 are detachably connected as a whole via a connector 190, so that when the internal structural parts of the electronic atomization device 100 are damaged, the internal structural parts of the electronic atomization device 100 can be replaced and repaired by releasing the connection between the first shell 170 and the second shell 180, thereby avoiding the need to scrap the entire electronic atomization device 100 when some structural parts of the electronic atomization device 100 fail.

[0050] In addition, referring to FIGS. 1 to 4 , the atomizer 110, the oil supply assembly 120 and the control assembly 160 can be detachably disposed inside the first shell 170 and the second shell 180, and the atomizer 110, the oil supply assembly 120 and the control assembly 160 are independent of each other. As in the present embodiment, the atomizer 110, the oil supply assembly 120 and the control assembly 160 are integrated into independent modules, so that when one or more of the atomizer 110, the oil supply assembly 120 and the control assembly 160 fails, the failed atomizer 110, the oil supply assembly 120 or the control assembly 160 can be replaced independently to achieve the reuse of the electronic atomization device 100, reduce the use cost of the electronic atomization device 100, and increase the user experience.

[0051] The technical features of the above-described embodiments may be arbitrarily combined.
