The bottom cover further includes: a liquid blocking portion, the liquid blocking portion extends from the top surface of the bottom cover towards the liquid injection port, and the liquid blocking portion is configured to close the liquid injection port when the bottom cover is in the first assembly position.

[0006] In some embodiments, when the bottom cover is in the first assembly position, the liquid blocking portion isolates the liquid storage chamber and the atomization component.

[0007] In some embodiments, the liquid blocking portion is further provided with a first liquid inlet hole, and the first liquid inlet hole is configured such that when the bottom cover is in the first assembly position, the two sides of the first liquid inlet hole are not in communication.

[0008] In some embodiments, the housing further provides a second assembly position, and the first liquid inlet hole is configured to connect the liquid storage chamber and the atomization component when the bottom cover is in the second assembly position.

[0009] In some embodiments, when the bottom cover moves along the length direction of the atomizer, the bottom cover moves towards the direction of the suction nozzle provided on the housing, so that the bottom cover moves from the first assembly position to the second assembly position.

[0010] In some embodiments, the liquid storage chamber includes at least two liquid storage cavities. The fixing member and the housing jointly enclose the liquid storage cavities. The number of the liquid blocking portions is at least two, and the first liquid inlet hole of one of the liquid blocking portions can correspond to the liquid outlet of one of the liquid storage cavities.

[0011] In some embodiments, the fixing member includes a fixing portion and a mounting portion. One end of the mounting portion is connected to the fixing portion. The fixing portion is movably clamped with the bottom cover, and the mounting portion can abut against the liquid blocking portion of the bottom cover.

[0012] In some embodiments, the mounting portion is provided with a second liquid inlet hole and a mounting groove. The second liquid inlet hole is arranged towards the liquid outlet of the liquid storage cavity.

Detailed Implementation Modes

[0028] The present application will be further described in detail below in conjunction with the accompanying drawings through specific implementation modes. Similar elements in different implementation modes are labeled with related similar element numbers. In the following implementation modes, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid overwhelming the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the field.

[0029] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0030] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation modes. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are the necessary sequences unless it is stated that a certain sequence must be followed.

[0031] The serial numbers assigned to components in this document itself, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connection (coupling).

[0032] In the related art, the atomizing device often leaks liquid. The atomizer adopts a method of separately arranging the liquid storage chamber and the atomization core. However, currently, the atomizing device with a separately arranged liquid storage chamber and atomization core requires more components, the structure of the atomizing device is relatively complex, the cost is relatively high, and the related operations are also inconvenient for consumers, affecting the user experience. In addition, in order to reduce the liquid leakage situation of the atomizing device on the market, an air passage with a bent structure is arranged at the position of the atomization core. The air passage with the bent structure will affect the flow of the aerosol formed by atomizing the atomization matrix. The material of the atomization core also adopts a ceramic atomization core, but the porosity of the ceramic atomization core is relatively low, affecting the atomization effect of the atomizing device, resulting in poor taste of the aerosol, and further affecting the user experience. Therefore, in order to improve the user experience, an atomizing device with a direct air passage can be adopted; the atomization core adopts a material with a relatively high porosity, such as a cotton core, to ensure the smooth flow of the aerosol and the edible taste. When the consumer uses the atomizing device, it takes at least a few seconds for the atomization matrix in the liquid storage chamber to flow into the atomization core. Otherwise, if the consumer uses it directly without waiting, it may cause damage to the atomization core or the situation that the atomization matrix is not atomized into aerosol, affecting the user's use feeling.

[0033] In this application, to prevent the atomization matrix from leaking in the atomizer before use, the atomizer 100 pre-wets the atomization component 140 during use.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 6, in some embodiments, the first aspect provides an atomizer 100, which includes a housing 160, a fixing member 130, an atomization assembly 140, and a bottom cover 120. The housing 160 has an opening 161 and a liquid storage chamber 110 is provided inside, and the liquid storage chamber 110 is used to store the atomization matrix. The fixing member 130 is provided with a liquid injection port 1311, and the fixing member 130 is disposed inside the housing 160; the atomization assembly 140 is positioned inside the fixing member 130, and the atomization assembly 140 is in fluid communication with the liquid storage chamber 110; the bottom cover 120 is connected to the opening 161, and the housing 160 provides at least one first assembly position suitable for keeping the bottom cover 120 and the housing 160 in relative positioning. The bottom cover 120 includes a liquid blocking portion 121, and the liquid blocking portion 121 extends from the top surface of the bottom cover 120 towards the liquid injection port 1311, and the liquid blocking portion 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 injects the atomization matrix into the liquid storage chamber 110, and when adding the atomization matrix to the liquid storage chamber 110 before installing the bottom cover 120, the purpose of wetting the core of the atomization assembly 140 can be achieved. When the bottom cover 120 closes the opening 161, the liquid blocking portion 121 closes the liquid injection port 1311, and the bottom cover 120 has at least one assembly position. One of the assembly positions can achieve closing the opening 161 of the bottom cover 120 and enabling the liquid blocking portion 121 of the bottom cover 120 to close the liquid injection port 1311. The bottom cover 120 can be removed to facilitate injecting the atomization matrix into the liquid storage chamber 110. The assembly position can also be multiple, without specific limitation. The above atomizer 100 is only one embodiment of the present application, and the rest of the specific structures inside the atomizer 100 will not be elaborated here. Exemplarily, the housing 160 defines an accommodation cavity 162 having an opening 161, and the accommodation cavity 162 is used to accommodate part or all of the atomization assembly 140, the fixing member 130, and the bottom cover 120, that is, the bottom cover 120 can move relatively inside the accommodation cavity 162.

[0035] In the present application, the position of the bottom cover 120 can change relative to the housing 160 and the fixing member 130. At this time, 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 housing 160, the atomization matrix is added to the liquid storage chamber 110 through the liquid injection port 1311 of the fixing member 130, and a small amount of the atomization matrix can flow into the atomization assembly 140. The atomization matrix in the atomization assembly 140 can achieve the effect of pre-wetting the core of the atomization assembly 140, improving the user experience. When the bottom cover 120 closes the opening 161 of the housing 160, the liquid blocking portion 121 of the bottom cover 120 closes the liquid injection port 1311 of the fixing member 130, achieving the purpose of blocking the atomization matrix from entering the atomization assembly 140, preventing the atomization matrix in the liquid storage chamber 110 from continuously flowing into the atomization assembly 140, so as to reduce the leakage of the atomization assembly 140 when the atomizer 100 is not in use.

[0036] It can be understood that pre-wetting the wick means that before the atomizer 100 is used, the atomization matrix enters the atomization component 140 to wet the heating element 143 in the atomization component 140, and the atomization matrix is heated by the heating element 143 to form an aerosol for the user to inhale. If the atomizer 100 is not wetted, there is a situation where the atomization matrix does not enter the heating element 143, and the heating element 143 may overheat and cause the cotton wick to be damaged or even carbonized, thus affecting the user experience. The atomizer 100 of the present application can achieve pre-wetting of the wick and prevent the heating element 143 from dry burning and heating.

[0037] In some embodiments, in combination with Figure 3 and Figure 4 As shown, the liquid blocking portion is further provided with a first liquid inlet hole 1211. The first liquid inlet hole 1211 is configured such that when the bottom cover 120 is in the first assembly position, the two sides of the first liquid inlet hole 1211 are not connected; the first liquid inlet hole 1211 is configured such that when the bottom cover 120 is in the second assembly position, the first liquid inlet hole 1211 connects the liquid storage chamber 110 and the atomization component 140. When the bottom cover 120 is in the first assembly position, the liquid blocking portion 121 isolates the liquid storage chamber 110 and the atomization component 140, achieving the purpose of separating the atomization matrix in the liquid storage chamber 110 from the atomization component 140, keeping the atomization matrix in a relatively fresh state, preventing the atomization matrix in the liquid storage chamber 110 from flowing into the atomization component 140 in advance, so as to avoid liquid leakage in the atomization component 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 connects the liquid storage chamber 110 and the atomization component 140, reducing the time for the atomization matrix to enter the atomization component 140. When the user uses it, the atomization matrix can quickly wet the wick of the atomization component 140, improving the user experience.

[0038] In addition, the first assembly position refers to the position where the bottom cover 120 is located before the atomizer 100 is used, that is, the position where the bottom cover 120 is located in the initial state of the atomizer 100 is the first assembly position. The second assembly position refers to the position where the bottom cover 120 is located after moving and when the atomizer 100 is in use.

[0039] Exemplarily, the cross-sectional area range of the first liquid inlet hole 1211 of the liquid blocking portion 121 is 0.010 mm 2 to 0.020 mm 2 , and the distance travel range for the atomization matrix to enter the atomization component 140 is 2 to 4 mm. For example, the cross-sectional area of the first liquid inlet hole 1211 of the liquid blocking portion 121 is 0.015 mm 2 , and the distance travel for the atomization matrix to enter the atomization component 140 is 3 mm. When the bottom cover 120 moves, the liquid storage chamber 110 increases by at least 0.045 mm 3The space forms a pressure difference to facilitate the rapid inflow of the atomization matrix into the atomization component 140, achieving the effect of quickly wetting the wick of the atomization component 140 and enhancing 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 is a circular structure or a square structure.

[0040] Combined with Figures 1 to 4 As shown, the atomizer 100 has a first direction X. Exemplarily, taking the height direction of the atomizer 100 as an example, the first direction X is the direction of the arrow in the figure. It can be understood that the above definitions are only for facilitating the understanding of the relative positional relationship of each part in the atomizer 100 and should not be construed as a limitation to this application.

[0041] In some embodiments, combined with Figure 3 and Figure 4 As shown, when the bottom cover 120 moves along the axial direction of the atomizer 100, that is, the length direction, that is, the bottom cover 120 moves along the first direction X, the bottom cover 120 moves in the direction towards the nozzle 163 provided on the housing 160, 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 of the atomizer 100, that is, the length direction, so that the bottom cover 120 moves in the direction towards the nozzle 163, and further move the bottom cover 120 to the second assembly position, so that the atomization matrix in the liquid storage chamber 110 can enter the atomization component 140 through the first liquid inlet hole 1211 of the liquid blocking portion 121.

[0042] Furthermore, referring to Figure 1 , the moving direction of the bottom cover 120 is parallel to the axial direction of the atomizer 100. Correspondingly, the axial direction of the atomizer 100 is the first direction X of the atomizer 100, that is, 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. Push the bottom cover 120 and make the bottom cover 120 move along the first direction X of the atomizer 100.

[0043] In some embodiments, please refer to Figure 3 and Figure 4, the liquid storage chamber 110 includes at least two liquid storage cavities 112. The fixing member 130 and the housing 160 jointly enclose the liquid storage cavity 112, and the liquid storage cavity 112 is used for storing the atomization matrix. The number of the liquid blocking parts 121 is at least two. The first liquid inlet hole 1211 of one liquid blocking part 121 can correspond to the liquid outlet 111 of one liquid storage cavity 112. Correspondingly, the atomization matrix in the liquid storage chamber 110 flows out through the liquid outlet 111 of the liquid storage cavity 112 to the atomization assembly 140. There are at least two liquid storage cavities 112, and the atomization matrices in the two liquid storage cavities 112 respectively flow into the atomization assembly 140 through the first liquid inlet holes 1211 of the corresponding liquid blocking parts 121, so as to ensure the capacity of the atomization matrix entering the atomization assembly 140 for rapid wicking, and further improve the atomization effect. Further, the two liquid blocking parts 121 are located at the same end of the bottom cover 120, and the two liquid blocking parts 121 are arranged in parallel. Of course, the number of the liquid blocking parts 121 can also be multiple, and the multiple liquid blocking parts 121 are arranged circumferentially, and one liquid blocking part 121 corresponds to one first liquid inlet hole 1211.

[0044] In some embodiments, referring to Figures 4 to 6 , the fixing member 130 includes a fixing part 131 and a mounting part 132. One end of the mounting part 132 is connected to the fixing part 131. The fixing part 131 is movably clamped with the bottom cover 120. The mounting part 132 can abut against the liquid blocking part 121 of the bottom cover 120. Correspondingly, the bottom cover 120 can move relative to the fixing part 131. The liquid blocking part 121 abuts against the mounting part 132 and forms a sealing structure with the mounting part 132 to prevent the atomization matrix in the liquid storage chamber 110 from flowing into the atomization assembly 140 in advance, so that the atomization matrix in the liquid storage chamber 110 is in a relatively fresh state. The fixing member 130 can be made of silica gel material. Of course, the fixing member 130 can also be made of other materials, for example, the material of the fixing member 130 is one of polyurethane, TPE, and latex.

[0045] Further, as Figure 4 shown, the fixing part 131 is provided with a through groove, and the liquid blocking part 121 of the bottom cover 120 is inserted into the through groove and abuts against the mounting part 132 to realize the connection between the bottom cover 120 and the fixing part 131.

[0046] In some embodiments, in combination with Figure 2 and Figure 3As shown in the figure, the installation part 132 is provided with a second liquid inlet hole 1321 and an installation groove 150. The installation groove 150 is used for fixing and limiting the atomization component 140. The second liquid inlet hole 1321 is arranged towards the liquid outlet 111 of the liquid storage cavity 112. The second liquid inlet hole 1321 can be communicated with the liquid outlet 111, so that the atomization matrix in the liquid storage cavity 112 flows into the installation groove 150 through the second liquid inlet hole 1321. That is, the second liquid inlet hole 1321 of the installation part 132 can be communicated with the liquid outlet 111 of the liquid storage cavity 112; or the liquid blocking part 121 can block the second liquid inlet hole 1321 and the liquid outlet 111 of the liquid storage cavity 112, and the liquid blocking part 121 of the bottom cover 120 can simultaneously block and seal the second liquid inlet hole 1321 and the liquid outlet 111 of the liquid storage cavity 112.

[0047] In the present application, as Figure 2 shown, the atomization component 140 includes an atomization part 141, a liquid guiding part 142 and a heating part 143. The liquid guiding part 142 wraps the heating part 143, and the liquid guiding part 142 is arranged in the atomization part 141. The atomization part 141 is arranged in the installation groove 150. The installation groove 150 realizes the limiting and installation of the atomization part 141. The liquid guiding part 142 is used for guiding the atomization matrix to the position of the heating part 143. The atomization matrix is heated by the heating part 143 to form an aerosol for the user to consume. Exemplarily, as Figure 7 shown, the atomization part 141 is an atomization tube with a hollow structure, and the liquid guiding part 142 is a liquid guiding cotton. The liquid guiding cotton is located in the atomization tube, and the atomization tube is installed in the installation groove 150. Of course, the material of the liquid guiding part 142 may affect the atomization effect and taste of the atomization matrix. The material of the liquid guiding part 142 can be cotton. Of course, the liquid guiding part 142 can also be selected from one of glass fiber or plant fiber.

[0048] Exemplarily, referring to Figure 4 and Figure 7 , the atomization part 141 is provided with a third liquid inlet hole 1411. The third liquid inlet hole 1411 is communicated with the second liquid inlet hole 1321. That is, the second liquid inlet hole 1321 of the installation part 132 and the third liquid inlet hole 1411 of the atomization part 141 are always in a communicated state, so as to facilitate the atomization matrix to quickly enter the atomization part 141 through the third liquid inlet hole 1411 of the atomization part 141 and infiltrate the liquid guiding part 142 and the heating part 143. The specific shapes of the third liquid inlet hole 1411 and the second liquid inlet hole 1321 are not limited, but the size specifications of the third liquid inlet hole 1411 and the second liquid inlet hole 1321 are adapted to each other. Exemplarily, both the third liquid inlet hole 1411 and the second liquid inlet hole 1321 are circular structures or square structures.

[0049] In some embodiments, in combination with Figure 4 and Figure 5As shown, the bottom cover 120 is provided with a first engaging portion 122, and the side wall of the accommodation cavity 162 is provided with a first slot 1621 and a second slot 1622. Correspondingly, when the bottom cover 120 moves from the first assembly position to the second assembly position, the first engaging portion 122 can move from the first slot 1621 to the second slot 1622. After the bottom cover 120 is moved, the atomization matrix can quickly flow into the atomization assembly 140, thereby shortening the time for the atomization matrix to enter the atomization assembly 140 and quickly wetting the wick of the atomization assembly 140.

[0050] The atomizer 100 can be a disposable product. The first engaging portion 122 is provided with an inverted buckle structure. After the first engaging portion 122 moves to the second slot 1622, it cannot move back to the first slot 1621 through the second slot 1622, realizing the fixation and limitation of the bottom cover 120 to ensure that the first liquid inlet hole 1211 of the liquid blocking portion 121 and the second liquid inlet hole 1321 always remain in a communicating state, ensuring that the atomization matrix enters the atomization assembly 140. In addition, the atomizer 100 can also be a cartridge replacement type product. The first engaging portion 122 can reciprocate between the second slot 1622 and the first slot 1621, thereby realizing the isolation or communication between the liquid storage chamber 110 and the atomization assembly 140.

[0051] Furthermore, as Figure 4 shown, the bottom cover 120 body is provided with a first engaging portion 122, and the side wall of the housing 160 is provided with a slot. The first engaging portion 122 is engaged with the slot, and the first engaging portion 122 and the slot form a snap structure. Exemplarily, the number of slots is two, and the two slots are arranged side by side along the first direction X, that is, the two slots are arranged along the first direction X of the atomizer 100.

[0052] In some embodiments, in a second aspect, an atomization device is provided, including a power supply component and the atomizer 100 in any of the above embodiments. The power supply component is used to supply power to the atomizer 100, and the atomizer 100 is used to heat the atomization matrix into an aerosol. The atomization device can be a disposable product or a cartridge replacement type product. For a disposable atomization device, the atomizer 100 is fixedly connected to the power supply component; for a cartridge replacement type atomization device, the atomizer 100 and the power supply component are detachably connected, and the atomizer 100 and the power supply component can be replaced according to the usage situation.
