DETAILED DESCRIPTION

[0033] The application will be described in further detail below with reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following description, many details are described in order to provide a more thorough understanding of the application. However, it will be apparent to one skilled in the art that some features, which are not described in detail, can be omitted, or can be substituted by other elements, materials, methods, etc. In some cases, some operations related to the application are not shown or described in the specification in order to avoid the core of the application being overwhelmed by excessive description, and it is not necessary for one skilled in the art to describe these related operations in detail according to the description in the specification and general technical knowledge in the art.

[0034] In the description of the application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "mount", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0035] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate way to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the order in the specification and the drawings is only for the purpose of clearly describing a certain embodiment, and does not mean that it is the necessary order, unless otherwise specified that a certain order must be followed.

[0036] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and have no technical meaning. Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connections (couplings).

[0037] In the related art, the atomization device often has a liquid leakage problem. The atomizer adopts a mode in which the liquid storage bin and the atomizing core are separately arranged. However, the atomization device with the liquid storage bin and the atomizing core separately arranged needs to be provided with more components, the structure of the atomization device is relatively complex, the cost is relatively high, and the related operation is relatively inconvenient for consumers, which affects the user experience. In addition, in order to reduce the liquid leakage problem, the atomization device on the market is provided with an air channel with a bending structure at the position of the atomizing core. The air channel with the bending structure affects the circulation of the aerosol formed by the atomized base material, and the material of the atomizing core is a ceramic atomizing core. However, the porosity of the ceramic atomizing core is low, which affects the atomization effect of the atomization device, causes poor taste of the aerosol, and further affects the user experience. Therefore, in order to improve the user experience, a straight-through air channel can be used. The atomizing core is made of a material with high porosity, such as a cotton core, to ensure smooth circulation of the aerosol and eating taste. When the consumer uses the atomization device, the atomization base material in the liquid storage bin can flow into the atomizing core only after waiting for at least a few seconds, otherwise the consumer may directly use it without waiting, which may cause damage to the atomizing core or the atomization base material is not atomized into an aerosol, affecting the user's experience.

[0038] In this application, the atomizer prevents the atomization base material from leaking before use. The atomizing assembly 140 of the atomizer 100 is pre-wetted when in use. In other words, the atomizer and the atomization device provided by the present application pre-wet the atomizing assembly, which can reduce the problem of atomization base material leakage before use of the atomization device.

[0039] Referring to FIG. 1, FIG. 2 and FIG. 6, in some embodiments, the present application provides an atomizer 100, the atomizer 100 comprises a housing 160, a fixing member 130, an atomization assembly 140 and a bottom cover 120. The housing 160 has an opening 161 and an inner liquid storage 110 for storing an atomization substrate. The fixing member 130 has a liquid injection port 1311, and the fixing member 130 is arranged in the housing 160. The atomization assembly 140 is arranged in the fixing member 130, and the atomization assembly 140 and the liquid storage 110 are in fluid communication. The bottom cover 120 is connected to the opening 161, and the housing 160 provides at least a first assembly position suitable for keeping the bottom cover 120 and the housing 160 in relative position. The bottom cover 120 comprises a liquid blocking part 121 extending from the top surface of the bottom cover 120 to the direction of the liquid injection port 1311, and the liquid blocking part 121 is configured to close the liquid injection port when the bottom cover 120 is in the first assembly position. When the bottom cover 120 does not close the opening 161, the liquid injection port 1311 is in fluid communication with the liquid storage 110, and the liquid injection port 1311 is used to inject the atomization substrate into the liquid storage 110, which can achieve the purpose of wetting the atomization assembly 140 before the bottom cover 120 is installed. When the bottom cover 120 closes the opening 161, the liquid blocking part 121 closes the liquid injection port 1311, and the bottom cover 120 has at least one assembly position which can achieve the purpose of closing the opening 161 by the bottom cover 120 and closing the liquid injection port 1311 by the liquid blocking part 121 of the bottom cover 120. The bottom cover 120 can be removed to inject the atomization substrate into the liquid storage 110. The assembly position can also be multiple, which is not limited specifically. The above-mentioned atomizer 100 is only one embodiment of the present application, and the remaining specific structure inside the atomizer 100 is not described here. Exemplarily, the housing 160 defines a receiving cavity 162 having an opening 161, and the receiving cavity 162 is used to accommodate part or all of the atomization assembly 140, the fixing member 130 and the bottom cover 120, i.e. the bottom cover 120 can be relatively movable in the receiving cavity 162.

[0040] In some embodiments, the position of the bottom cover 120 can be changed relative to the shell 160 and the fixing member 130, and the relative position of the fixing member 130 and the atomization assembly 140 remains unchanged. When the bottom cover 120 does not close the opening 161 of the shell 160, the atomization substrate is added to the liquid storage compartment 110 through the liquid injection port 1311 of the fixing member 130, and a small amount of atomization substrate can flow into the atomization assembly 140. The atomization substrate in the atomization assembly 140 can achieve the effect of pre-wetting the atomization assembly 140, improve the user experience, and the liquid injection port 1311 of the fixing member 130 is closed by the liquid blocking part 121 of the bottom cover 120 when the bottom cover 120 closes the opening 161 of the shell 160. The purpose of blocking the atomization substrate from entering the atomization assembly 140 is achieved, and the continuous flow of the atomization substrate in the liquid storage compartment 110 into the atomization assembly 140 is prevented to reduce the risk of liquid leakage in the atomization assembly 140 when the atomizer 100 is not in use.

[0041] It can be understood that pre-wetting refers to that before the atomizer 100 is used, the atomization substrate enters the heating element 143 in the atomization assembly 140 to wet the heating element 143, and the atomization substrate is heated by the heating element 143 to form an aerosol for the user to smoke. If the atomizer 100 is not pre-wetted, the atomization substrate does not enter the heating element 143, and the heating element 143 is easily overheated, which can cause damage to the cotton core and even carbonization, thereby affecting the user experience. The atomizer 100 of the present application can achieve pre-wetting and prevent the heating element 143 from overheating.

[0042] In some embodiments, as shown in FIGS. 3 and 4, the liquid blocking part is further provided with a first liquid inlet hole 1211, which is configured to be not communicated on both sides when the bottom cover 120 is in the first assembly position; the first liquid inlet hole 1211 is configured to communicate the liquid storage compartment 110 and the atomization assembly 140 when the bottom cover 120 is in the second assembly position. When the bottom cover 120 is in the first assembly position, the liquid blocking part 121 isolates the liquid storage compartment 110 and the atomization assembly 140, achieving the purpose of separating the atomization substrate in the liquid storage compartment 110 from the atomization assembly 140, keeping the atomization substrate in a fresh state, and preventing the atomization substrate in the liquid storage compartment 110 from flowing into the atomization assembly 140 in advance to avoid liquid leakage in the atomization assembly 140 when the atomizer 100 is not in use; when the bottom cover 120 is in the second assembly position, the first liquid inlet hole 1211 communicates the liquid storage compartment 110 and the atomization assembly 140, reducing the time of the atomization substrate entering the atomization assembly 140, and achieving the purpose of quickly wetting the atomization assembly 140 with the atomization substrate when the user uses it, thereby improving the user experience.

[0043] In addition, the first assembly position refers to the position of the bottom cover 120 before the atomizer 100 is used, i.e., the position of the bottom cover 120 when the atomizer 100 is in an initial state. The second assembly position refers to the position of the bottom cover 120 after the atomizer 100 is used.

[0044] In some embodiments, the first liquid inlet hole 1211 of the liquid blocking portion 121 has a cross-sectional area ranging from 0.010 mm 2 to 0.020 mm 2 , and the distance traveled by the atomized substrate into the atomization assembly 140 ranges from 2 mm to 4 mm. For example, the first liquid inlet hole 1211 of the liquid blocking portion 121 has a cross-sectional area of 0.015 mm 2 , the distance traveled by the atomized substrate into the atomization assembly 140 is 3 mm, and the liquid storage tank 110 increases by at least 0.045 mm 3 of space when the bottom cover 120 moves, thereby forming a pressure difference to facilitate the rapid flow of the atomized substrate into the atomization assembly 140, achieving the effect of quickly wetting the atomization assembly 140 and improving the user experience. In this application, the specific shape of the first liquid inlet hole 1211 is not limited, and the first liquid inlet hole 1211 can be circular or square.

[0045] In combination with FIGS. 1-4, the atomizer 100 has a first direction X. In some embodiments, the first direction X is in the height direction of the atomizer 100, and the first direction X is the arrow direction in the drawings. It can be understood that the above definition is only for the convenience of understanding the relative positional relationship of each part in the atomizer 100, and should not be understood as a limitation of the present application.

[0046] In some embodiments, in combination with FIGS. 3 and 4, when the bottom cover 120 moves along the axial direction, i.e., the length direction of the atomizer 100, i.e., the bottom cover 120 moves along the first direction X, the bottom cover 120 moves towards the direction of the mouthpiece 163, so that the bottom cover 120 moves from the first assembly position to the second assembly position. The user can push the bottom cover 120 to move along the axial direction, i.e., the length direction of the atomizer 100, so that the bottom cover 120 moves towards the direction of the mouthpiece 163, and then the bottom cover 120 moves to the second assembly position, so that the atomized substrate of the liquid storage tank 110 can enter the atomization assembly 140 through the first liquid inlet hole 1211 of the liquid blocking portion 121.

[0047] In some embodiments, referring to FIG. 1, the moving direction of the bottom cover 120 is parallel to the axial direction of the atomizer 100, and accordingly, the axial direction of the atomizer 100 is the first direction X of the atomizer 100, i.e., the length direction of the atomizer 100, and the moving direction of the bottom cover 120 is the first direction X of the atomizer 100, i.e., the length direction of the atomizer 100. The bottom cover 120 is pushed and moved along the first direction X of the atomizer 100.

[0048] In some embodiments, referring to FIGS. 3 and 4, the liquid storage bin 110 includes at least two liquid storage cavities 112, and the fixing member 130 and the shell 160 jointly enclose the liquid storage cavities 112, which are used to store the atomization substrate. The number of the liquid blocking portions 121 is multiple, i.e., at least two. The first liquid inlet hole 1211 of one liquid blocking portion 121 can correspond to the liquid outlet 111 of one liquid storage cavity 112. Accordingly, the atomization substrate of the liquid storage bin 110 flows out of the liquid outlet 111 of the liquid storage cavity 112 to the atomization assembly 140. The liquid storage bin 110 is provided with at least two liquid storage cavities 112. The atomization substrates in the two liquid storage cavities 112 flow into the atomization assembly 140 through the corresponding first liquid inlet holes 1211 of the liquid blocking portions 121, respectively, so as to ensure the capacity of the atomization substrate entering the atomization assembly 140 to quickly wet the wick and further improve the atomization effect. In some embodiments, the at least two liquid blocking portions 121 are located on the same side of the bottom cover 120, and the at least two liquid blocking portions 121 are arranged in parallel with each other. Of course, the number of the liquid blocking portions 121 can also be multiple.

One end of the mounting portion 132 is connected with the fixing portion 131. The fixing portion 131 is movably connected with the bottom cover 120. The mounting portion 132 can abut against the liquid blocking portion 121 of the bottom cover 120. Accordingly, the bottom cover 120 can be moved relative to the fixing portion 131. The liquid blocking portion 121 abuts against and forms a sealing structure with the mounting portion 132, so as to prevent the atomization substrate in the liquid storage bin 110 from flowing into the atomization assembly 140 in advance, so that the atomization substrate of the liquid storage bin 110 is in a relatively fresh state. The fixing member 130 can be made of silica gel. Of course, the fixing member 130 can also be made of other materials, such as one of polyurethane, TPE, and latex.

[0050] In some embodiments, as shown in FIG. 4, the fixing portion 131 is provided with a through slot.

The specific shape of the third liquid inlet hole 1411 and the second liquid inlet hole 1321 is not limited, but the size specifications of the third liquid inlet hole 1411 and the second liquid inlet hole 1321 are adapted. In some embodiments, the third liquid inlet hole 1411 and the second liquid inlet hole 1321 are circular structures or square structures.
