[0010] A driving chamber, disposed between the atomizing channel and the oil blocking member;

[0011] A driving medium is disposed in the driving cavity. The driving medium is a thermal expansion and contraction medium. When the driving medium is at room temperature, the oil baffle is located at a first position. When the driving medium expands due to heat, the driving medium pushes the oil baffle to move to the second position.

[0012] In some embodiments, the atomization channel and the oil baffle are both arranged inside the liquid storage cavity, the oil baffle is sleeved on the outside of the atomization channel, the outer wall of the atomization channel is provided with a first flange, and the oil baffle is provided with a second flange extending from the oil baffle to the outer wall of the atomization channel, the first flange, the outer wall of the atomization channel, the second flange and the inner wall of the oil baffle enclose the driving cavity.

[0013] In some embodiments, two ends of the atomization channel are an air inlet end and an air outlet end, respectively, and the oil inlet hole is closer to the air inlet end than the driving cavity.

[0016] In some embodiments, the oil baffle is spaced apart from one end of the base close to the atomization channel, so that when the oil baffle is covered on the base, a reserve liquid cavity is formed around the oil inlet, and the reserve liquid cavity is connected to the oil inlet.

[0017] In some embodiments, the oil blocking member comprises:

[0018] a first cylinder, wherein the second flange is provided at one end of the first cylinder;

[0019] The second cylinder is sleeved on the inner side or the outer side of the first cylinder, the thickness of the second cylinder is smaller than that of the first cylinder, and the end of the second cylinder corresponding to the air inlet end protrudes out of the end of the first cylinder corresponding to the air inlet end, so that when the oil baffle is in the first state, the second cylinder abuts against the base to close the oil inlet hole.

[0030] The benefit of the present application lies in that the oil baffle is driven to move by the thermal expansion and contraction of the driving medium, a driving cavity is set, and the driving medium is set in the driving cavity. When the driving medium is a medium that melts due to heat, the driving medium can be better sealed in the driving cavity to prevent the driving medium from leaking out. In the present application, when the electronic atomization device is in use, due to the power-on heating of the heating component, the driving medium expands due to the heat, pushing the oil baffle to move from the first position to the second position, opening the oil inlet, and the smoke oil can flow out of the liquid storage cavity and be heated and atomized. When the electronic atomization device is not in use, the driving medium is at room temperature, the oil baffle remains in the first position, the oil inlet is closed, and the smoke oil cannot flow out of the liquid storage cavity. Therefore, the oil inlet can be automatically opened and closed according to the working state of the electronic atomization device to prevent oil leakage, thereby improving the reliability of the product.

[0054] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] The present application embodiment provides an atomizer. Figures 1 to 7 As shown, the atomizer 100 is applied to the electronic atomization device 10. Please refer to Figure 1 and Figure 2 As shown, in the embodiment of the present application, the electronic atomization device 10 is an electronic cigarette, and the atomizer 100 is a cigarette cartridge of the electronic cigarette. In other optional embodiments, the electronic atomization device 10 can also be other types of electronic atomization devices, such as a medical electronic atomization device.

[0056] like Figure 4a and Figure 4b As shown, the atomizer 100 includes an oil storage member 110 , an atomization channel 120 , a heating component 130 , an oil blocking member 140 , a driving chamber 1401 and a driving medium 1402 .

[0057] The oil storage member 110 is provided with a liquid storage chamber 1101 inside, and the liquid storage chamber 1101 is used to store the smoke oil. Figure 8 As shown, the side wall of the atomization channel 120 is provided with an oil inlet hole 1201, which connects the atomization channel 120 with the liquid storage chamber 1101, so that the tobacco oil in the liquid storage chamber 1101 enters the atomization channel 120 through the oil inlet hole 1201. A heating component 130 is arranged in the atomization channel 120, and the heating component 130 can heat the tobacco oil entering the atomization channel 120 to form an aerosol for the user to inhale.

[0058] Combination Figure 4a and Figure 8 The oil blocking member 140 is slidably connected to the outside of the atomizing channel 120, and the oil blocking member 140 can move along the longitudinal direction of the atomizing channel 120. The longitudinal direction is the vertical direction of the electronic cigarette 10, or the up-down direction. That is to say, the oil blocking member 140 can move up and down outside the atomizing channel 120. The oil blocking member 140 has a first position ( Figure 4a ) and the second position ( Figure 4b ), the oil blocking member 140 is driven to switch between the second position and the first position by the thermal expansion and contraction of the driving medium 1402, thereby controlling the opening and closing of the oil inlet hole 1201. When the oil blocking member 140 is in the first position, as shown in FIG. Figure 4a As shown, the oil blocking member 140 covers the outside of the oil inlet hole 1201, and the oil blocking member 140 closes the oil inlet hole 1201, so that the smoke oil in the liquid storage chamber 1101 cannot flow into the atomization channel 120; when the oil blocking member 140 is in the second position, as shown in FIG. Figure 4bAs shown, the oil baffle 140 is lifted upward, removing the obstruction to the oil inlet 1201. The oil inlet 1201 is opened, and the smoke oil in the liquid storage chamber 1101 can flow into the atomization channel 120, and the smoke oil atomization operation can be performed. The thermal expansion and contraction of the driving medium 1402 is controlled by the start-up and shutdown of the electronic cigarette. After the electronic cigarette is started, the heating component 130 generates heat to heat the driving medium 1402, and the driving medium 1402 expands due to the heat and pushes the oil baffle 140. On the contrary, after the electronic cigarette is turned off, the heating component 130 stops generating heat, the driving medium 1402 cools and retracts, and the oil baffle 140 is sucked back downward. That is to say, the oil baffle 140 of the above-mentioned atomizer 100 can automatically control the opening and closing of the oil inlet 1201 according to the start-up and shutdown of the electronic cigarette, so as to prevent oil leakage when the electronic cigarette is not in use.

[0059] like Figure 4a and Figure 8 As shown, a driving cavity 1401 is provided between the atomizing channel 120 and the oil blocking member 140, and the driving cavity 1401 is a closed cavity. A driving medium 1402 is provided in the driving cavity 1401, and the driving medium 1402 is a thermal expansion and cold contraction medium. As mentioned above, when the driving medium 1402 is at room temperature, the oil blocking member 140 is located at the first position, and when the driving medium 1402 is heated and expanded, the driving medium 1402 pushes the oil blocking member 140 to move to the second position.

[0060] A closed driving cavity 1401 is designed to place the driving medium 1402. When the driving medium 1402 is a medium that melts when heated, the driving medium 1402 can be better sealed in the driving cavity 1401 to prevent the driving medium 1402 from leaking out.

[0061] In one embodiment, paraffin can be selected as the driving medium 1402. The principle of thermal expansion and contraction of paraffin is already known in the prior art and will not be described in detail here.

[0062] In one embodiment, the temperature of the paraffin wax when heated and expanded is 40°C-80°C, so that the paraffin wax can be ensured to melt and expand at a suitable temperature, push the oil blocking member 140 away, and avoid the atomizer core from burning dry. At the same time, the paraffin wax can be prevented from melting and expanding at a lower temperature. Preferably, the temperature of the paraffin wax when heated and expanded is selected to be 50°C.

[0063] In one embodiment, if Figure 4a and Figure 4b As shown, the atomizing channel 120 and the oil blocking member 140 are both disposed inside the liquid storage chamber 1101. In other optional embodiments, the atomizing channel 120 may also be disposed below the liquid storage chamber 1101, which is not limited here. Figure 4a and Figure 8 The oil blocking member 140 is sleeved on the outer side of the atomizing channel 120, and the oil blocking member 140 can be configured as a cylinder. Figure 4a , Figure 8 and Fig. 9 As shown, the outer wall of the atomizing channel 120 is provided with a first flange 1203, and the first flange 1203 extends from the outer wall of the atomizing channel 120 to the oil baffle 140. The oil baffle 140 is provided with a second flange 1403 extending from the oil baffle 140 to the outer wall of the atomizing channel 120, and the first flange 1203, the outer wall of the atomizing channel 120, the second flange 1403 and the inner wall of the oil baffle 140 enclose a driving chamber 1401. The driving medium 1402 is arranged in the driving chamber 1401. The formation structure of the above-mentioned driving chamber 1401 is simple, and the side walls of the atomizing channel 120 and the oil baffle 140 are fully utilized to enclose and form the driving chamber 1401, without the need for additional cumbersome structures, simplifying the structure, reducing the number of parts, and thus reducing the overall volume.

[0064] like Figure 4a and Figure 8 As shown, the two ends of the atomization channel 120 are the air inlet end A and the air outlet end B, respectively. The external airflow enters the atomization channel 120 from the air inlet end A, takes away the aerosol in the atomization channel 120, and then flows out from the air outlet end B of the atomization channel 120, flows to the mouthpiece of the electronic cigarette, and is inhaled into the mouth of the user. The oil inlet hole 1201 is closer to the air inlet end A than the drive cavity 1401. That is to say, the oil inlet hole 1201 is located below the drive cavity 1401, so that the oil inlet hole 1201 is closer to the bottom of the atomization channel 120, and also closer to the bottom of the liquid storage cavity 1101, so that the smoke oil at the bottom of the liquid storage cavity 1101 can be used up, avoiding residual smoke oil that cannot be used up. At the same time, designing the driving chamber 1401 above the oil inlet hole 1201 is also more conducive to opening and closing the oil inlet hole 1201 by moving the oil baffle 140 up and down, and the oil inlet hole 1201 can be closed directly by abutting the bottom end of the oil baffle 140 against the bottom wall of the liquid storage chamber 1101. If the driving chamber 1401 is designed below the oil inlet hole 1201, the overall structure will be more complicated.

[0065] like Figure 4a As shown, the atomizer 100 further includes a base 150. The oil storage member 110 has an open end, and the base 150 is disposed at the open end of the oil storage member 110 to close the liquid storage chamber 1101. Figure 4a, the bottom end of the oil storage part 110 is open, and the base 150 is arranged at the bottom end of the oil storage part 110. The air inlet end A of the atomization channel 120 is inserted into the base 150, and the air outlet end B of the atomization channel 120 is inserted into the top wall of the oil storage part 110, so that the inner wall of the oil storage part 110, the outer wall of the atomization channel 120 and the base 150 define and close the liquid storage chamber 1101, and the smoke oil can only flow out of the liquid storage chamber 1101 from the oil inlet hole 1201 on the side wall of the atomization channel 120, so that the smoke oil can be controlled by controlling the opening and closing of the oil inlet hole 1201. It can be understood that the base 150 and the top wall of the oil storage part 110 are respectively provided with through holes corresponding to the air inlet end A and the air outlet end B of the atomization channel 120, so that the atomization channel 120 is connected to the outside of the liquid storage chamber 1101, realizing the functions of air intake and air outlet. The oil baffle 140 is cylindrical, and when the oil baffle 140 is in the first state, as shown in FIG4 , the oil baffle 140 is covered on the base 150 to close the oil inlet hole 1201. The cylindrical oil baffle 140 is more convenient to assemble the oil baffle 140 on the atomizing channel 120, and the cylindrical oil baffle 140 only needs to be sleeved outside the atomizing channel 120, which is convenient for assembly.

[0066] Further, as shown in FIG. 4 , the oil baffle 140 is spaced apart from one end of the base 150 and the atomization channel 120 . As shown in FIG. 4 , the above design enables the oil baffle 140 to be covered on the base 150 , and a circle of reserve liquid chamber 1404 is formed around the oil inlet hole 1201 , and the reserve liquid chamber 1404 is connected to the oil inlet hole 1201 . The setting of the reserve liquid chamber 1404 can prevent the heating component 130 from dry burning during the initial suction. During the initial suction, since it takes time for the temperature to rise to the thermal expansion temperature of the driving medium 1402 , the oil baffle 140 cannot be opened in time, and the liquid storage chamber 1101 cannot provide the heating component 130 with tobacco oil in time. At this time, the tobacco oil in the reserve liquid chamber 1401 can be used. Since the reserve liquid chamber 1401 is connected to the oil inlet hole 1201 , the tobacco oil therein can flow from the oil inlet hole 1201 to the heating component 130 at any time, preventing the heating component 130 from dry burning.

[0067] Further, such as Figure 8 As shown, the atomizer 100 further includes a first seal 161 and a second seal 162. The first seal 161 and the second seal 162 are arranged between the oil retaining member 140 and the atomizing channel 120 to seal the driving chamber 1401. The first seal 161 and the second seal 162 are respectively arranged at both ends of the driving chamber 1401 in the longitudinal direction, and are used to seal the two ends of the driving chamber 1401.

[0068] like Figure 8As shown, the first seal 161 is arranged on the first flange 1203 to seal the gap between the first flange 1203 and the inner wall of the oil retaining member 140. The second seal 162 is arranged on the inner side of the second flange 1403 (the inner side of the second flange 1403 refers to the side of the second flange 1403 close to the driving chamber 1401), and the second seal 162 is longitudinally limited by the second flange 1403. The second seal 162 abuts against the second flange 1403 on one side in the longitudinal direction, and abuts against the driving medium 1402 on the other side in the longitudinal direction. The second seal 162 abuts against the outer side wall of the atomizing channel 120 on one side in the transverse direction, and abuts against the inner side wall of the oil retaining member 140 on the other side in the transverse direction. Thereby, the gap between the atomizing channel 120 and the oil retaining member 140 is sealed. When the driving medium 1402 expands, it pushes the second seal 162 and the oil retaining member 140 to move synchronously.

[0069] In one embodiment, if Fig. 9 As shown, the oil retaining member 140 includes a first cylinder 141 and a second cylinder 142. The second flange 1403 is disposed at one end of the first cylinder 141. The second cylinder 142 is sleeved on the inner side or the outer side of the first cylinder 141. Fig. 9 As shown, the second cylinder 142 is sleeved on the inner side of the first cylinder 141. The second cylinder 142 can be fixed on the first cylinder 141 by interference fit. In the present application, the thickness of the second cylinder 142 is set to be less than the thickness of the first cylinder 141, that is, the second cylinder 142 is set to be thinner. Figure 8 As shown, the end of the second cylinder 142 corresponding to the air inlet end A of the atomizing channel 120 protrudes from the end of the first cylinder 141 corresponding to the air inlet end A of the atomizing channel 120, that is, the bottom end of the second cylinder 142 extends out of the bottom end of the first cylinder 141, so that when the oil blocking member 140 is in the first state, as shown in FIG. Figure 4a As shown, the second cylinder 142 abuts against the base 150 to close the oil inlet hole 1201. Since the second cylinder 142 is relatively thin, the sealing effect is better when it abuts against the base 150. The thicker first cylinder 141 is helpful to improve the structural rigidity of the entire oil blocking member 140.

[0070] In the present application embodiment, Fig. 9 As shown, the first cylinder 141 is arranged outside the second cylinder 142. The first cylinder 141 is relatively thick. The thicker first cylinder 141 is arranged outside so that the first cylinder 141 serves as a heat-insulating layer. The material of the first cylinder 141 can be silicone, and of course other heat-insulating materials can also be selected. The heat-insulating layer can make the temperature of the driving medium rise faster, thereby improving the response rate of the oil blocking member 140.

[0071] In one embodiment, if Figure 8As shown, a plurality of oil inlet holes 1201 may be provided, and the plurality of oil inlet holes 1201 are arranged around the circumference of the atomization channel 120 to form a circle of oil inlet holes 1201 to improve the oil intake effect.

[0072] As shown in FIG4 , in one embodiment, the heating component 130 includes an oil-guiding cotton 131 and a heating wire 132. The oil-guiding cotton 131 is arranged inside the atomization channel 120, and the smoke oil flows into the oil-guiding cotton 131 after entering from the oil inlet hole 1201 of the atomization channel 120. The heating wire 132 is arranged inside the oil-guiding cotton 131, and a channel is arranged at the center of the oil-guiding cotton 131. The heating wire 132 is attached to the inner wall of the channel, so as to heat and atomize the smoke oil in the oil-guiding cotton 131.

[0073] Furthermore, the heating component 130 may also include an oil storage cotton 133, which is arranged on the outside of the oil guide cotton 131, and the oil storage cotton 133 is arranged in contact with the inner wall of the atomization channel 120. The oil storage cotton 133 can store smoke oil, so that the heating wire 132 can be supplied with oil through the oil storage cotton 133 when the oil blocking member 140 is not opened, and sufficient smoke oil can be stored to supply the heating wire 132 to avoid dry burning of the heating wire 132 during initial inhalation. The smoke oil stored in the oil storage cotton 133 flows to the heating wire 132 through the oil guide cotton 131. It can be understood that the oil storage cotton 133 is arranged corresponding to the oil inlet hole 1201, so as to receive the smoke oil entering from the oil inlet hole 1201.

[0074] The present application also provides an electronic atomization device 10. Figures 1 to 3 , Figures 5 to 7 As shown, the electronic atomization device 10 includes the above-mentioned atomizer 100, and also includes a nozzle assembly 200 and a battery assembly 300. The nozzle assembly 200 and the battery assembly 300 are respectively arranged at two ends of the atomizer 100 in the longitudinal direction. Figure 2 and Figure 3 As shown, the nozzle of the nozzle assembly 200 is connected to the atomization channel 120. The side wall of the battery assembly 300 is provided with an air inlet 301, as shown in FIG. Figure 3 As shown, in the present application, the air inlet 301 is arranged at the bottom of the battery assembly 300. The atomization channel 120 is connected with the air inlet 301 through the inner cavity of the battery assembly 300, so that the outside air can enter the battery inner cavity from the air inlet 301 and then enter the atomization channel 120. The battery assembly 300 is electrically connected to the heating assembly 130, so that the battery assembly 300 supplies power to the heating assembly 130.

[0075] In one embodiment, if Figure 2As shown, a secondary liquid storage chamber 201 is provided in the suction nozzle assembly 200, and the secondary liquid storage chamber 201 can also store tobacco oil. After the atomizer 100 is connected to the suction nozzle assembly 200, the tobacco oil in the secondary liquid storage chamber 201 can be added to the liquid storage chamber 1101 of the atomizer 100. The provision of the secondary liquid storage chamber 201 increases the total amount of tobacco oil in the electronic cigarette and prolongs the use time. Specifically, as an embodiment in which the secondary liquid storage chamber 201 is connected to the liquid storage chamber 1101, a puncture structure 170 can be provided on at least one of the atomizer 100 and the suction nozzle assembly 200, and the puncture structure 170 can puncture the other of the atomizer 100 and the suction nozzle assembly 200 to connect the secondary liquid storage chamber 201 with the liquid storage chamber 1101.

[0076] The puncture structure 170 may be provided on the atomizer 100, or on the nozzle assembly 200, or on both the atomizer 100 and the nozzle assembly 200. Figure 5 As shown, the puncture structure 170 is disposed on the atomizer 100. The number of the puncture structures 170 is not limited and can be reasonably arranged as needed, for example, one, two, three, four, etc.
