Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters denote similar items in the following drawings; therefore, once an item is defined in one drawing, no further discussion thereof is required in subsequent drawings.

[0033] In one aspect, the present application provides a liquid storage structure. Please referring to FIGS. 1-7, the liquid storage structure includes a housing 11, a stiffener 12, and a mounting base 13. The housing 11 is configured to form a receiving room 111 and a mounting opening 112 in communication with the receiving room 111. The stiffener 12 is at least partially disposed at the mounting opening 112 for preventing the mounting opening 112 from deforming, so that the mounting opening 112 can maintain a preset shape. The mounting base 13 is hermetically connected to a mounting end of the housing 11 at the mounting opening 112 and is at least partially disposed at an inner side of the stiffener 12. The mounting base 13 together with at least the housing 11 is jointly configured to form a liquid storage chamber 14, and the liquid storage chamber 14 is configured for containing an aerosol-forming material. The mounting end of the housing 11 surrounds the mounting opening 112 and the stiffener 12 is at least partially disposed at the mounting end of the housing 11.

[0034] By arranging the stiffener 12 at the mounting opening 112 which is configured for connecting the mounting base 13, the strength of the mounting end of the housing 11 at the mounting opening 112 is enhanced under the action of the stiffener 12, and the mounting end of the housing 11 at the mounting opening 112 is not prone to deformation. This enables the housing 11 to cooperate with the mounting base 13 to form a hermetic connection at the mounting opening 112 under the action of the stiffener 12, thereby allowing an effective hermetic connection to be maintained between the housing 11 and the mounting base 13 at the mounting opening 112. Further, the liquid storage chamber 14 defined at least by the mounting base 13 and the housing 11 can achieve a good sealing effect, thereby ensuring that the aerosol-forming material contained in the liquid storage chamber 14 does not leak from the connection between the mounting base 13 and the housing 11 at the mounting opening 112.

[0035] In one further example, please referring to FIGS. 2 and 4-5, the stiffener 12 is integrally formed with the housing 11, and the stiffener 12 is made of a rigid material that is not prone to deformation. This not only ensures higher connection strength between the stiffener 12 and the housing 11 but also eliminates the need for assembly operations between the stiffener 12 and the housing 11.

[0036] It should be noted that the stiffener 12 may be made of a rigid metal material, such as food-grade stainless steel, aluminum alloy, and the like, which will not be enumerated one by one herein; alternatively, the stiffener 12 may be made of a food-grade plastic-steel material, which is not limited herein.

[0037] In one embodiment, the stiffener 12 is integrally formed with the housing 11, the stiffener 12 is disposed on an inner surface of the mounting end of the housing 11 at the mounting opening 112 and faces the mounting opening 112, so that the mounting base 13 is hermetically connected to the inner side of the stiffener 12. This facilitates the molding operation of the stiffener 12 and the housing 11, and enables the stiffener 12 to directly form a hermetic connection with the mounting base 13.

[0038] In other embodiments, the stiffener 12 may alternatively be integrally formed inside the mounting end of the housing 11; or the stiffener 12 may be integrally formed on the housing 11 and disposed on an outer surface of the mounting end of the housing 11 at the mounting opening 112 and faces away from the mounting opening 112.

[0039] In one further example, please referring to FIGS. 2-3 and 6-7, the mounting base 13 includes a base body 131 and a sealing member 132. The sealing member 132 may be integrally formed on the base body 131 and sealed between the base body 131 and the housing 11 at the mounting opening 112. This ensures high connection strength between the sealing member 132 and the base body 131, thereby reducing the risk of the sealing member 132 detaching from the base body 131 and eliminating the need for assembly operations between the sealing member 132 and the base body 131.

[0040] In one further example, please referring to FIG. 6, the base body 131 and the sealing member 132 are interlocked with each other. The base body 131 and the sealing member 132 provide mutual movement limitation to each other, thereby ensuring that the sealing member 132 can be tightly connected to the base body 131 and is not prone to detaching from the base body 131. Thus, during the process of assembling the mounting base 13 into the housing 11 at the mounting opening 112, the sealing member 132 can be effectively prevented from displacing relative to the base body 131 to ensure the sealing effect.

[0041] In one further example, the sealing member 132 is disposed over a top portion of the base body 131, and a limiting hole 1321 is formed in the sealing member 132. A limiting portion 1311 is formed on the base body 131, and the limiting portion 1311 is engaged in the limiting hole 1321.

[0042] In one further example, please referring to FIGS. 6-7 the limiting portion 1311 includes a first protrusion 1312 and a second protrusion 1313. The first protrusion 1312 is disposed on the side surface of the base body 131, and the second protrusion 1313 is disposed on the end surface of the base body 131 that faces the receiving room 111. The limiting hole 1321 includes a first hole 13211 and a second hole 13212. The first protrusion 1312 is engaged in the first hole 13211, and the second protrusion 1313 is engaged in the second hole 13212.

[0043] By arranging the first protrusion 1312 on the side surface and the second protrusion 1313 on the end surface of the base body 131, and arranging the first hole 13211 corresponding to the first protrusion 1312 and the second hole 13212 corresponding to the second protrusion 1313 in the sealing member 132, the sealing member 132 can be mutually limited and connected with the base body 131 both in a plane of the end surface and in a circumferential direction of the base body 131. Thus, during the process of inserting the mounting base 13 into the mounting opening 112, the sealing member 132 can maintain substantially synchronous movement with the base body 131, thereby enabling the sealing member 132 to effectively form a hermetic connection between the base body 131 and the mounting opening 112.

[0044] In one further example, at least two first protrusions 1312 are formed on the side surface of the base body 131. Along the circumferential direction of the base body 131, a limiting groove 1314 is formed at intervals between two adjacent ones of the at least two first protrusions 1312, so that at least two limiting grooves 1314 are formed on the base body 131.

[0045] Please referring to FIGS. 6-7, the sealing member 132 includes a ring portion 1322. The ring portion 1322 includes a first ring body 13221, a second ring body 13223, and at least two connecting bodies 13222. The first ring body 13221 and the second ring body 13223 are disposed at an interval along the direction in which the mounting base 13 is inserted into the mounting opening 112. At least two connecting body 13222 are disposed at an interval along the circumferential direction of the base body 131, and each connecting body 13222 is connected between the first ring body 13221 and the second ring body 13223 along the direction in which the mounting base 13 is inserted into the mounting opening 112, so that the first ring body 13221 and the second ring body 13223 achieve an engaged connection. The first ring body 13221 is formed with at least one sealing groove along the circumferential direction of the first ring body 13221, and the second ring body 13223 is formed with at least one sealing groove along the circumferential direction of the second ring body 13223.

[0046] Two adjacent connecting bodies 13222 and the first ring body 13221 as well as the second ring body 13223 together form a first holes 13211, and each connecting body 13222 is respectively engaged to a corresponding limiting groove 1314. This further improves the mutual limiting connection strength between the sealing member 132 and the base body 131, thereby effectively preventing the sealing member 132 from displacing relative to the base body 131 along the circumferential direction of the base body 131.

[0047] In one further example, a plurality of second protrusions 1313 are formed on the end surface of the base body 131 that faces the receiving room 111, and the plurality of second protrusions 1313 are disposed at intervals on the end surface of the base body 131.

[0048] Please referring to FIGS. 6-7, The sealing member 132 includes an end portion 1323. A plurality of second holes 13212 are formed on the end portion 1323, and each second hole 13212 is respectively engaged in the corresponding second protrusion 1313. Since each of the plurality of second protrusions 1313 is engaged in the corresponding second hole 13212, the end portion 1323 is hermetically connected with the end surface, the end portion1323 can be effectively prevented from displacing relative to the end surface, thereby preventing the ring portion 1322 from displacing relative to the side surface of the base body 131.

[0049] In one further example, please referring to FIGS. 2-5, the stiffener 12 is integrally formed on the housing 11 and disposed on the inner side of the mounting opening 112; and the first ring body 13221 is hermetically connected to the inner surface of the stiffener 12; or the second ring body 13223 is hermetically connected to the inner surface of the stiffener 12; or the first ring body 13221 and the second ring body 13223 are respectively hermetically connected to the inner surface of the stiffener 12.

[0050] By arranging at least one of the first ring body 13221 and the second ring body 13223 to be directly connected to the inner surface of the stiffener 12, a good sealing effect is achieved for the connection between the base body 131 and the housing 11, and the deformation of the mounting opening 112 is effectively prevented under the action of the stiffener 12. Thus, the aerosol-forming material contained in the liquid storage chamber 14 does not leak from the connection between the first ring body 13221 and the stiffener 12 and the connection between the second ring body 13223 and the stiffener 12.

[0051] In one further example, please referring to FIG. 2 an atomizing assembly is disposed in the liquid storage structure. The atomizing assembly is configured for heating the aerosol-forming material supplied from the liquid storage chamber 14, so that the heated aerosol-forming material is atomized to generate an aerosol. The atomizing assembly includes an air inlet end 21 and an air outlet end 22 opposite to the air inlet end 21. The air inlet end 21 is configured for allowing external air flow to enter into an atomization channel 23 of the atomizing assembly, so that the generated aerosol is mixed with the air flow passing through the atomization channel 23. The air outlet end 22 is configured for allowing the mixture of the aerosol and the air flow to exit the atomization channel 23.

[0052] In one further example, please referring to FIGS. 2-4, the housing 11 is configured to form a mouthpiece portion 113. The mouthpiece portion 113 includes a mouthpiece end 1131 and a connecting end 1132 opposite to the mouthpiece end 1131. The mouthpiece end 1131 is configured for a user to inhale. The air outlet end 22 is hermetically inserted into the connecting end 1132, so that the mouthpiece portion 113 is hermetically communicated to the air outlet end 22 of the atomization channel 23.

[0053] The base body 131 is configured to form an insertion hole 1315, and the insertion hole 1315 faces the connecting end 1132. A first sealing hole 1324 corresponding to the insertion hole 1315 is formed on the end portion 1323. The air inlet end 21 passes through the first sealing hole 1324 and extends into the insertion hole 1315, so that the air inlet end 21 is in communication with the outside through the insertion hole 1315. This allows external air flow to enter through the insertion hole 1315, flow through the atomization channel 23 and the mouthpiece portion 113 in sequence, and then exit, and mix with the generated aerosol in the atomization channel 23.

[0054] In one further example, please referring to FIG. 2, a sealing ring 3 is disposed in the insertion hole 1315, and the sealing ring 3 is configured for sealing between the inner surface of the insertion hole 1315 and the outer surface of the air inlet end 21.

[0055] In one further example, please referring to FIGS. 2-3 and 6-7, the base body 131 is configured to form a buffer cavity 1316 and a liquid guiding hole 1317. The liquid guiding hole 1317 communicates between the buffer cavity 1316 and the liquid storage chamber 14, and is configured for allowing the aerosol-forming material in the liquid storage chamber 14 to flow to the buffer cavity 1316 in a communication state.

[0056] The atomizing assembly includes an atomizing tube and an atomizing core 25. The mounting base 13 together with at least the housing 11 and the atomizing tube is jointly configured to form the liquid storage chamber14, the air inlet end 21 and the air outlet end 22 are respectively disposed at the two opposite ends of the atomizing tube. The atomizing tube is provided with a liquid passing hole 243 at the buffer cavity 1316. The atomizing core 25 is disposed in the atomizing tube and disposed at the liquid passing hole 243. The aerosol-forming material in the buffer cavity 1316 flows to the atomizing core 25 through the liquid passing hole 243, and is heated and atomized by the atomizing core 25 to generate an aerosol.

[0057] In one further example, please referring to FIG. 2, a control member 4 is further disposed in the liquid storage structure. The control member 4 is configured for blocking or opening the liquid guiding hole 1317. When the control member 4 blocks the liquid guiding hole 1317, the liquid storage chamber 14 and the buffer cavity 1316 are separated into two independent spaces; when the control member 4 opens the liquid guiding hole 1317, the liquid storage chamber 14 and the buffer cavity 1316 are in communication with each other.

[0058] A second sealing hole 1325 is formed on the end portion 1323 and corresponds to the liquid guiding hole 1317. When the control member 4 blocks the liquid guiding hole 1317, at least part of the control member 4 is inserted into the second sealing hole 1325.

[0059] By arranging the control member 4 and the buffer cavity 1316, the user can open the liquid guiding hole 1317 during use, so that the aerosol-forming material in the liquid storage chamber 14 is continuously supplied to the buffer cavity 1316, and the aerosol-forming material in the buffer cavity 1316 is continuously supplied to the atomizing core 25 through the liquid passing hole 243, thereby realizing continuous supply of the aerosol-forming material. When the user is not using the device, the control member 4 can be set to block the liquid guiding hole 1317, thereby avoiding direct communication between the liquid passing hole 243 and the liquid storage chamber 14, which would otherwise result in high hydraulic pressure at the liquid passing hole 243 and thus cause the risk of the aerosol-forming material leaking from the liquid passing hole during non-use.

[0060] In one further example, please referring to FIGS. 2-4, a liquid injection hole 114 is formed in the housing 11. The liquid injection hole 114 communicates the liquid storage chamber 14 with the outside, and a liquid injection plug 5 is detachably disposed in the liquid injection hole 114. The liquid injection plug 5 is configured for blocking the liquid injection hole 114. When it is necessary to inject the aerosol-forming material into the liquid storage chamber 14, the liquid injection plug 5 is removed to open the liquid injection hole 114, and the aerosol-forming material can be injected into the liquid storage chamber 14 through the liquid injection hole 114. When there is no need to inject the aerosol-forming material into the liquid storage chamber 14, the liquid injection hole 114 can be blocked by the liquid injection plug 5.

[0061] In one further example, please referring to FIGS. 8-9 a plurality of insertion portions 115 are disposed on the end surface of the housing 11 that is opposite to the mouthpiece end 1131, and a plurality of matching limiting insertion holes 1318 corresponding to the plurality of insertion portions 115 are formed on the base body 131. Alternatively, a plurality of limiting insertion holes 1318 are disposed on the end surface of the housing 11 that is opposite to the mouthpiece end 1131, and a matching insertion portion 115 is respectively formed on the base body 131 corresponding to each limiting insertion hole 1318. When the plurality of insertion portions 115 are inserted into the corresponding limiting insertion holes 1318, the base body 131 is hermetically connected to the housing 11, and under the cooperation of the limiting insertion holes 1318 and the insertion portions 115, the mounting base 13 can be further restricted from moving along the radial direction of the mounting opening 112.

[0062] In another aspect, the present application further provides an atomizer. The atomizer includes the liquid storage structure described in any one of the above. Therefore, the atomizer has all the beneficial effects described above, which will not be repeated herein.

[0063] In one further example, please referring to FIG. 2 the atomizer further includes the atomizing assembly described above, and the atomizing assembly is configured for heating and volatilizing the aerosol-forming material supplied from the liquid storage chamber 14. The atomizing assembly further includes a first liquid guiding cotton 26. The atomizing tube includes an inner atomizing tube 241 and an outer atomizing tube 242. The inner atomizing tube 241 is disposed in the outer atomizing tube 242, and the first liquid guiding cotton 26 is filled between the outer wall of the inner atomizing tube 241 and the inner wall of the outer atomizing tube 242.
