[0030] As Figure 1 , Figure 2 and Figure 3 shown, some embodiments of the present application disclose a liquid storage container 1, including a pressure regulating structure 11 and a container body 12 for storing a liquid matrix. The pressure regulating structure 11 includes a base body 111, a liquid-proof air-permeable member 112, and a cover body 113, specifically as follows:
[0031] As Figure 4 shown, the base body 111 has a first air-permeable portion 1111. The base body 111 is installed on the container body 12, and the first air-permeable portion 1111 is in gas conduction communication with the inside of the container body 12. The liquid-proof air-permeable member 112 is provided in the air-permeable path of the first air-permeable portion 1111, and the liquid-proof air-permeable member 112 is used to allow air flow through and block the liquid matrix. The cover body 113 has a second air-permeable portion 1131 that is in gas conduction communication with the outside. The cover body 113 is installed on the base body 111, and there is an air-permeable channel between the second air-permeable portion 1131 and the first air-permeable portion 1111.
[0032] Among them, the liquid-proof and breathable member 112 allows air flow but blocks the passage of the liquid matrix, so as to control the air pressure inside the container body 12 by maintaining breathability while preventing the liquid matrix inside the container body 12 from leaking from the first breathable part 1111, avoiding abnormal internal pressure in the container body 12, enabling smooth liquid discharge from the container body 12, and improving the user experience. At the same time, there may be a liquid leakage situation at the liquid outlet 122 of the container body 12 during liquid discharge. The breathable channel can delay the inflow of the liquid matrix outside the liquid storage container 1 into the first breathable part 1111, avoiding blocking one side of the liquid-proof and breathable member 112.
[0033] In some embodiments, the breathable channel is curved, such as S-shaped or V-shaped, etc. The S-shape and V-shape here are only examples and do not limit the present application. It can also be other shapes.
[0034] In some embodiments, as Figure 4 shown, the first breathable part 1111 is a hollow structure that penetrates the entire seat body 111. There is an installation step 11111 inside the first breathable part 1111, and the liquid-proof and breathable member 112 is arranged on the installation step 11111. For example, the liquid-proof and breathable member 112 is a waterproof breathable membrane. The waterproof breathable membrane here is only an example and does not limit the present application. In some other embodiments, the liquid-proof and breathable member 112 can be integrally formed with the inside of the first breathable part 1111.
[0035] In some embodiments, as Figure 3 and Figure 4 shown, the seat body 111 includes a lower seat 1112 and an upper seat 1113 that are opposite in its height direction. The first breathable part 1111 penetrates the lower seat 1112 and the upper seat 1113, and the lower seat 1112 is used to be installed on the container body 12. For example, the lower seat 1112 is a tubular structure, and an external thread is provided on the outer wall surface of the lower seat 1112, and an internal thread is provided on the inner wall surface of the breathable port 121 of the container body 12. The seat body 111 is installed on the container body 12 through thread cooperation. The tubular structure and thread cooperation here are only examples and do not limit the present application.
[0036] In some embodiments, as Figure 3 and Figure 4 shown, the pressure regulating structure 11 further includes a sealing body 114, and the sealing body 114 is arranged at the connection between the seat body 111 (i.e., the lower seat 1112) and the container body 12. For example, the sealing body 114 is a sealing ring, and the sealing ring is a ring body made of an elastic material (such as rubber or SBS synthetic material). The sealing ring is sleeved in the lower seat 1112. After the seat body 111 rotates and moves a certain distance through thread cooperation, the upper seat 1113 presses the sealing ring against the container body 12 to achieve sealing.
[0037] In some embodiments, as Figure 3 andFigure 5 As shown, the ventilation channel includes a third ventilation portion 11132. The upper seat 1113 includes a first peripheral wall 11131 extending in its height direction, that is, a wall body in the circumferential direction. The third ventilation portion 11132 is provided on the first peripheral wall 11131. The second ventilation portion 1131 is in air conduction communication with the first ventilation portion 1111 through the third ventilation portion 11132. For example, the second ventilation portion 1131 includes at least one ventilation groove, and in some embodiments, includes a plurality of ventilation grooves. The plurality of ventilation grooves are evenly spaced along the circumferential direction on the side wall 1132 of the cover body 113. The third ventilation portion 11132 includes at least one ventilation hole, and in some embodiments, includes a plurality of ventilation holes. The plurality of ventilation holes are evenly spaced along the circumferential direction on the first peripheral wall 11131. It can be understood that at least one can be one, two or any number. The ventilation grooves and ventilation holes here are only examples and do not limit the present application.
[0038] In some other embodiments, the ventilation channel includes a third ventilation portion 11132. The upper seat 1113 includes a first peripheral wall 11131 extending in its height direction. The cover body 113 is sleeved on the upper seat 1113, and the cover body 113 is spaced from the top of the first peripheral wall 11131 to form the third ventilation portion 11132.
[0039] In some embodiments, as Figure 4 shown, the liquid-proof ventilation member 112 is located below the third ventilation portion 11132 and divides the first ventilation portion 1111 into a first ventilation space and a second ventilation space. The liquid-proof ventilation member 112 is located below the third ventilation portion 11132, which can prevent the liquid matrix inside the container body 12 from leaking out through the third ventilation portion 11132.
[0040] In some embodiments, as Figure 5 shown, the ventilation channel further includes a fourth ventilation portion 11134 and a liquid storage tank 11135. The upper seat 1113 further includes a second peripheral wall 11133 extending in its height direction, that is, a wall body in the circumferential direction. The second peripheral wall 11133 is located on the outer peripheral edge of the first peripheral wall 11131, and the second peripheral wall 11133 is spaced from the first peripheral wall 11131 to form the liquid storage tank 11135. The fourth ventilation portion 11134 is provided on the second peripheral wall 11133. The second ventilation portion 1131 is in air conduction communication with the first ventilation portion 1111 through the fourth ventilation portion 11134, the liquid storage tank 11135 and the third ventilation portion 11132. For example, the fourth ventilation portion 11134 includes at least one ventilation groove, and in some embodiments, includes a plurality of ventilation grooves. The plurality of ventilation grooves are evenly spaced along the circumferential direction on the second peripheral wall 11133. It can be understood that at least one can be one, two or any number. The ventilation grooves here are only examples and do not limit the present application.
[0041] Among them, the liquid storage tank 11135 can temporarily store the flowing liquid matrix, preventing it from flowing into the first breathable part 1111 and blocking one side of the liquid-proof breathable part 112.
[0042] In some other embodiments, the breathable channel further includes a fourth breathable part 11134 and a liquid storage tank 11135. The upper seat 1113 further includes a second peripheral wall 11133 extending in its height direction. The second peripheral wall 11133 is located at the outer peripheral edge of the first peripheral wall 11131, and the second peripheral wall 11133 is spaced from the first peripheral wall 11131 to form the liquid storage tank 11135. The cover body 113 is spaced from the top of the second peripheral wall 11133 to form the fourth breathable part 11134.
[0043] In some embodiments, the third breathable part 11132 provided on the first peripheral wall 11131 and the fourth breathable part 11134 provided on the second peripheral wall 11133 are correspondingly arranged in position or are arranged in a staggered manner as shown in Figure 5 When arranged in a staggered manner, the flow-in of the liquid matrix can be further delayed.
[0044] In some embodiments, as shown in Figure 3 The second peripheral wall 11133 includes a lower wall 11133A and an upper wall 11133B that are opposite to each other in its height direction. The second breathable part 1131 is provided on the side wall 1132 of the cover body 113, the fourth breathable part 11134 is provided on the upper wall 11133B, and the inner wall surface of the side wall 1132 is at least in close contact with the outer wall surface of the lower wall 11133A.
[0045] In some embodiments, the second breathable part 1131 and the fourth breathable part 11134 are correspondingly arranged in position. At this time, the inner wall surface of the side wall 1132 can be in close contact with the outer wall surface of the upper wall 11133B or there is a gap between the two.
[0046] In some other embodiments, there is a gap between the inner wall surface of the side wall 1132 and the outer wall surface of the upper wall 11133B, and the second breathable part 1131 and the fourth breathable part 11134 are arranged in a staggered manner in position. When arranged in a staggered manner, the flow-in of the liquid matrix can be further delayed. For example, the gap is 0.1 mm or 0.5 mm, etc. The 0.1 mm and 0.5 mm here are only examples and do not limit the present application.
[0047] In some embodiments, as shown in Figure 2 、 Figure 3 and Figure 4As shown, the pressure regulating structure 11 further includes a retaining net 115, which is disposed around the outer periphery of the side wall 1132 of the cover body 113. For example, the retaining net 115 is a steel net or an aluminum net, and its aperture is smaller than a preset value (such as 1 mm or 2 mm). When the aperture is relatively small, it can play a certain blocking role to prevent the liquid matrix outside the container body 12 from flowing in. The steel net, aluminum net, 1 mm, and 2 mm here are only examples and are not intended to limit the present application.
[0048] As Figure 6 As shown, some embodiments of the present application disclose an electronic atomization device, including a liquid storage container 1 for storing a liquid aerosol generating matrix and an atomizer 2. The liquid storage container 1 will not be described in detail here.
[0049] The atomizer 2 includes an atomization core and a heating element disposed on the atomization core. During use, the atomization core absorbs the liquid aerosol generating matrix through the liquid outlet 122 of the container body 12, and the heating element is energized to generate heat, so that the liquid aerosol generating matrix in the atomization core is atomized. The user inhales through the suction port of the atomizer 2, and air enters the atomization core from the air intake channel of the atomizer 2 under the action of suction, mixes with the atomized aerosol in the atomization core, and is discharged from the suction port after passing through the air outlet channel of the atomizer 2.
[0050] By implementing the present application, the following beneficial effects are achieved:
[0051] In the liquid storage container of the present application, the seat body of the pressure regulating structure is installed on the container body, so that the first air permeable part of the seat body is in internal air conduction communication with the container body, and the liquid-proof air permeable member is disposed in the air permeable path of the first air permeable part. The liquid-proof air permeable member can allow air flow to pass through but can block the liquid matrix from passing through. Thus, while preventing the liquid matrix inside the container body from leaking from the first air permeable part, the air pressure inside the container body is controlled by maintaining air permeability, avoiding abnormal pressure inside the container body, making the liquid outlet of the container body smooth, and improving the user experience.
[0052] At the same time, the cover body is installed on the seat body, and there is an air permeable channel between the second air permeable part of the cover body and the first air permeable part of the seat body. The air permeable channel can delay the inflow of the liquid matrix outside the liquid storage container into the first air permeable part, avoiding blocking one side of the liquid-proof air permeable member.
[0053] It is understandable that the above embodiments only represent some implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, the above embodiments or technical features can be freely combined, and several deformations and improvements can also be made, which all fall within the protection scope of the present application, that is, the embodiments described in "in some embodiments" can be freely combined with any of the above and below embodiments.
