[0040] See also Figure 1 and Figure 3 , an embodiment of the present application provides a liquid storage component, which is used in an electronic atomization device, including a shell 1 and an elastic component 2. The shell 1 is used to accommodate an oil tank for storing atomized liquid, and the number of oil tanks accommodated in the shell 1 is at least two. By enabling the shell 1 to accommodate multiple oil tanks at one time, the user can replace one oil tank with another one for use after one of the oil tanks is used up, and the user can replace another oil tank with other flavors for use when the user wants to change the flavor, so as to facilitate the user to carry oil tanks of different flavors and carry multiple oil tanks. The elastic component 2 is arranged in the shell 1 and abuts against the spare oil tank, so that after the user takes out the oil tank that needs to be replaced from the shell 1, the elastic component 2 can use its elasticity to adjust the position of the spare oil tank, so that the spare oil tank is moved to a designated position for use, which is convenient for the user's replacement operation.

[0041] See also Figure 1-Figure 4 In the specific configuration, the housing 1 has a containing cavity, and the containing cavity has a first position 3 and a second position 4 which are sequentially arranged along a first direction and communicated with each other, and the first position 3 and the second position 4 are both used to accommodate the oil tank, and the oil tank can move between the first position 3 and the second position 4. The housing also has a vent 13 and a suction port 14 communicating with the containing cavity, and the suction port 14 is located at the first position 3, and the vent 13 is located at the first position 3 or the second position 4. The user can give suction to the suction port 14, so that the gas outside the housing 1 enters the oil tank at the first position 3 or the second position 4 through the vent 13, and is finally sucked out after passing through the oil tank at the first position 3 and the suction port 14.

[0042] The oil tank has an air passage and an air inlet and an air outlet connected to the air passage. The oil tank is accommodated in the housing 1, and the air outlet is connected to the suction port 14. The gas outside the housing 1 enters the air inlet of the oil tank through the vent 13, and is sucked into the suction port 14 through the air outlet of the oil tank to be sucked out by the user.

[0043] Specifically, the oil tank includes a tank body and a liquid storage component. The tank body is used to accommodate the liquid storage component. The liquid storage component is oil storage cotton, which is used to absorb and store the atomized liquid. Specifically, the air inlet and the air outlet are arranged on the tank body, and the liquid storage component is arranged inside the tank body, and has an atomization channel connecting the air inlet and the air outlet. When the oil tank is placed in the shell 1, the gas outside the shell 1 can enter the air inlet and the atomization channel of the oil tank in sequence through the air vent 13, and be sucked out through the air outlet and the suction port 14. Among them, the cross-sectional area of ​​the oil tank perpendicular to the extension direction of the air channel corresponds to the cross-sectional area of ​​the accommodating cavity perpendicular to the extension direction of the air channel.

[0044] The elastic component 2 is located between the housing 1 and the oil tank, and is used to push the oil tank to a preset position. Figure 1-Figure 4 , the elastic component 2 is arranged in the housing 1 and is away from the vent 13. The elastic component 2 is configured to push the oil tank in the housing 1 to move along the first direction, so as to push the oil tank to the first position 3 and communicate with the vent 13, or to the second position 4 and communicate with the vent 14. That is, the elastic component 2 is arranged in the housing 1 and abuts against the spare oil tank. The pushing direction of the elastic component 2 is the first direction. After the oil tank to be replaced is taken out of the housing 1, the elastic component 2 can push the spare oil tank to a position close to the vent 13, so as to assist the user in the replacement operation.

[0045] When the liquid storage component of the present application is in use, the shell 1 can simultaneously accommodate multiple oil tanks, so that the user can take out one of the oil tanks when one of the oil tanks is used up or wants to change the flavor, and move the other oil tank to the suction port 14 under the action of the elastic component 2 to replace the previous oil tank for use, so as to facilitate users to carry oil tanks of different flavors and carry multiple oil tanks, reduce the use cost and recycling cost, and improve the environmental performance of the product.

[0046] See also Figure 1 and Figure 2 In one embodiment, the liquid storage component includes multiple oil tanks, which are arranged in sequence along the extension direction of the air passage, and the air inlet of one oil tank of two adjacent oil tanks is connected to the air outlet of the other oil tank, one end of the elastic component 2 abuts against the position where the suction port 14 is set in the shell 1, and the other end of the elastic component 2 abuts against the air outlet of the oil tank, wherein the elastic component is in a compressed state.

[0047] Specifically, the two oil tanks are stacked inside the shell 1 in a direction parallel to the axis of the vent 13, and the vent 13 and the suction port 14 are connected to the two oil tanks located at the first position 3 and the second position 4. When the oil tank located at the second position 4 is taken out of the shell 1, the oil tank located at the first position 3 moves to the second position 4 under the action of its own gravity and the pushing action of the conical spring.

[0048] In one of the embodiments, the shell 1 further has a suction pipe 15 extending from the edge of the suction port 14 of the shell 1, the suction pipe 15 is located in the accommodating cavity, and the end of the elastic component 2 facing away from the oil tank is sleeved on the suction pipe 15 to ensure the stability between the elastic component 2 and the shell 1, and enhance the stability of the elastic component 2 when compressed and released in the shell 1.

[0049] Among them, it can be ensured that there is a large contact area between the elastic component 2 and the oil bin, so that the elastic component 2 and the oil bin have good stability, and the elastic component 2 includes at least one of a coil spring, a volute spring, and a leaf spring. Specifically, along the axial direction of the suction port 14, the elastic component 2 has a first end face and a second end face, the area of ​​the second end face is larger than the area of ​​the first end face, the first end face is sleeved on the suction pipe 15 and abuts against the shell, and the second end face abuts against the top surface of the oil bin located at the first position 3. When both oil bins are located inside the shell 1, the elastic component 2 is in a compressed state. When one of the oil bins is taken out of the shell 1, the elastic component 2 is stretched and reset, so that the other oil bin moves to the second position 4 under its own gravity and the push of the elastic component 2.

[0050] See also Figure 3-Figure 4 In one embodiment, the liquid storage component includes a plurality of oil tanks, which are arranged side by side and abut against each other. The plurality of oil tanks include a first oil tank and a second oil tank located at both ends thereof, wherein the air outlet of the first oil tank is connected to the suction port, one end of the elastic component 2 abuts against the inner wall of the accommodating cavity, and the other end of the elastic component 2 abuts against the second oil tank. Specifically, refer to Figure 3 and Figure 4 The first oil tank and the second oil tank are placed flat in the shell 1 along the direction perpendicular to the axis of the air inlet 13, and the two sides of the first oil tank at the first position 3 are respectively abutted against one of the inner side surfaces of the outer shell 11 and the second oil tank at the second position 4, and the two sides of the second oil tank at the second position 4 are respectively abutted against the first oil tank at the first position 3 and the elastic component 2.

[0051] See also Figure 1-Figure 4 In one embodiment, the elastic component 2 includes an elastic member 21 and an abutment member 22. The elastic member 21 is disposed on the housing 1, and the elastic force direction of the elastic member 21 is parallel to the arrangement direction of the multiple oil bins. The abutment member 22 is disposed on the elastic member 21, and the abutment member 22 is used to abut against the oil bin. The elasticity of the elastic member 21 enables the oil bin to be pushed to the first position 3 or the second position 4. The abutment member 22 can ensure that the elastic component 2 has a larger contact area with the oil bin, so that the elastic component 2 has better stability with the oil bin.

[0052] Specifically, see Figure 3-Figure 4In another embodiment, the elastic member 21 is a compression spring, the abutment member 22 is a baffle, the elastic direction of the compression spring is perpendicular to the axial direction of the suction port 14, and the two ends of the elastic direction of the compression spring are respectively arranged on the inner side surface of the housing 1 and the baffle, and the baffle abuts against the side surface of the oil bin at the second position 4. The baffle has an abutment surface, and the shape of the abutment surface is adapted to the shape of the outer peripheral wall of the oil bin to enhance the stability of the baffle after abutting against the oil bin.

[0053] In addition, see Figure 3-Figure 5 In this embodiment, the housing 1 includes a shell body 11 and a base 12 disposed on the shell body 11. The base 12 is provided with a mounting portion, which is located inside the shell body 11 and fits with the inner side of the shell body 11. A first connecting structure 23 is provided on the side of the mounting portion facing the baffle, and a second connecting structure 24 is provided on the side of the baffle facing the mounting portion. When the elastic member 21 is compressed to the limit position, the first connecting structure 23 can be connected with the second connecting structure 24 by snapping, so as to enhance stability. The two ends of the elastic member 21 in the elastic direction are respectively sleeved on the first connecting structure 23 and the second connecting structure 24, and snapped with the first connecting structure 23 and / or the second connecting structure 24, so that the first connecting structure 23 and the second connecting structure 24 can also assist the installation of the elastic member 21.

[0054] It is worth mentioning that see Figure 3-Figure 5 In the above embodiment, a suction pipe 15 is provided in the housing 1, and the suction pipe 15 connects the first oil tank 3 and the suction port 14. The tops of the two oil tanks can be partially accommodated inside the bottom of the suction pipe 15 to ensure the sealing effect between the two oil tanks and the first housing 11 when in use. That is, when one of the oil tanks is located at the first position 3, the top of the oil tank is located inside the bottom of the suction pipe 15 and abuts against the inner circumference of the suction pipe 15. After the external gas enters the oil tank through the vent 13, the gas in the oil tank can directly enter the suction port 14 through the suction pipe 15, and no leakage will occur.

[0055] See also Figure 1-Figure 2 In one embodiment, the housing 1 includes a housing body 11 and a base 12, the base 12 is disposed on the housing body 11 and cooperates with the housing body 11 to form a receiving cavity, the first position 3 and the second position 4 are both disposed in the receiving cavity, and the vent 13 and the suction port 14 are respectively disposed on the base 12 and the housing body 11. The housing body 11 and the base 12 are connected in a detachable manner or in a fixed manner.

[0056] Specifically, see Figure 1-Figure 2In one embodiment, the shell body 11 is made of food-grade plastic injection molding, and the base 12 is made of environmentally friendly silicone. The base 12 is detachably arranged on the shell body 11. When the atomized liquid in one of the oil tanks is consumed, the base 12 can be removed from the shell body 11, and the oil tank can be taken out of the shell body 11, so that the other oil tank is moved to the vent 13 under the drive of the elastic component 2 to realize the replacement of the oil tank.

[0057] See also Figure 3-Figure 5 In another embodiment, the shell body 11 is made of food-grade plastic injection molding, and the base 12 is made of environmentally friendly silicone. The base 12 is snap-fitted and fixed on the shell body 11 and cannot be detached from the shell body 11. In order to allow both oil tanks to be taken out from the shell body 1, in this embodiment, along the axial direction perpendicular to the vent 13, the opening area of ​​the vent 13 is larger than the maximum cross-sectional area of ​​the oil tank, so that the oil tank can be directly loaded into the shell body 11 through the vent 13, or taken out from the shell body 11 through the vent 13. When the atomized liquid in one of the oil tanks is consumed, the oil tank can be directly taken out of the shell body 11 through the vent 13, so that the other oil tank is moved to the vent 13 under the drive of the elastic component 2 to achieve the replacement of the oil tank.

[0058] See also Figure 6-Figure 9 , the embodiment of the present application further provides an electronic atomization device, comprising a housing 5 and a liquid storage assembly in any of the above embodiments, the housing 5 being detachably arranged on the housing 1. An atomization core 52 is arranged on the housing 5, and the atomization core 52 can be inserted into the housing 1 through the vent 13 to be inserted into the oil tank. That is, after the housing 5 is connected to the housing 1, the atomization core 52 can be inserted into the oil tank at the first position 3 or the oil tank at the second position 4 through the vent 13 to heat and atomize the atomized liquid in the corresponding oil tank.

[0059] Specifically, see Figure 6 and Figure 8 , a power supply assembly 51 is provided in the shell 5, an atomizer core 52 is provided on the shell 5, and a heating element thereof is electrically connected to the power supply assembly 51. When the housing 1 is connected to the shell 5, the atomizer core 52 can be partially inserted into the oil tank and contact the liquid storage element of the oil tank, so that the heating element can heat and atomize the atomized liquid in the liquid storage element contacting the atomizer core 52.

[0060] That is, in the embodiment of the present application, both oil tanks include a tank body and a liquid storage part, the tank body is provided with an air inlet and an air outlet, the liquid storage part is arranged inside the tank body, and has an atomization channel connecting the air inlet and the air outlet. When the oil tank is located at the first position 3 near the air vent 13, the atomizer core 52 can be partially inserted into the oil tank at the first position 3 after the shell 1 is connected to the outer shell 5, and contact the liquid storage part of the oil tank, and the power supply component 51 can heat and atomize the atomized liquid in the liquid storage part of the oil tank after the heating element is powered by the power supply component 51. When the oil tank is located at the second position 4 near the air vent 13, the atomizer core 52 can be partially inserted into the oil tank at the second position 4 after the shell 1 is connected to the outer shell 5, and contact the liquid storage part of the oil tank, and the power supply component 51 can heat and atomize the atomized liquid in the liquid storage part of the oil tank after the power supply component 51 is powered by the heating element.

[0061] See also Figure 8 In one embodiment, a housing 5 is further provided with a housing chamber 53, and the housing chamber 53 is used to accommodate an oil tank. By providing the housing chamber 53, the number of oil tanks that the electronic atomization device can carry at one time is increased, so that when both oil tanks in the liquid storage component are used up, or when the user wants to replace the flavor other than the two oil tanks, the oil tank in the housing chamber 53 can be taken out from the housing 5 and placed in the shell 1 for use.

[0062] Specifically, the accommodating chamber opens on the side of the shell 5 facing the vent 13, and extends inwardly along the axial direction of the vent 13. When the shell 1 is connected to the shell 5, the shell 1 covers the notch of the accommodating chamber and abuts against the oil tank in the accommodating chamber 53 to ensure the stability of the oil tank in the shell 5. When you want to replace the oil tank in the accommodating chamber 53, you can first separate the shell 1 from the shell 5 so that the notch of the accommodating chamber is exposed by the departure of the shell 1, and then take out the oil tank in the accommodating chamber 53, and then put it into the shell 1 to complete the replacement operation. Subsequently, the shell 1 can be connected to the shell 5, so that the atomizer core 52 is partially inserted into the replaced oil tank and contacts the liquid storage part of the oil tank, so that after the power supply assembly 51 supplies power to the heating element, the heating element can heat and atomize the atomized liquid in the liquid storage part of the oil tank, thereby realizing the use of the oil tank.

[0063] When the electronic atomization device of the present application is in use, the shell 1 can simultaneously accommodate multiple oil tanks, so that the user can take out one of the oil tanks when one of the oil tanks is used up or wants to change the flavor, and move another oil tank to the air inlet under the action of the elastic component to replace the previous oil tank for use, so as to facilitate users to carry oil tanks of different flavors and carry multiple oil tanks, reduce the use cost and recycling cost, and improve the environmental performance of the product.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
