[0033] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. 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, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and 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 description in the specification and the general technical knowledge in the art.

[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] Existing products can only be provided with a single aerosol matrix, and the operation of replacing aerosols with different flavors or functions is cumbersome. In addition, the aerosol matrix loaded in existing products is often pre-mixed, and the ratio of the ingredients such as flavors and base oils is fixed, and users cannot freely combine them. To solve the above problems, in the present application, the pump liquid component can selectively pump the aerosol matrix of at least one liquid storage device into the mixing chamber to achieve the change of flavor.

[0037] See also Figures 1 to 8 In one embodiment, an atomizing device 1 is provided. The atomizing device 1 mainly includes a liquid mixing chamber 10, a loading area 20, a liquid pump assembly 30 and an atomizing assembly 40. In one embodiment, the atomizing device 1 further includes a switching mechanism 50 and a housing assembly 60.

[0038] Among them, the mixing chamber 10 is used to provide a space for mixing the selected liquid materials, and to accommodate and store the aerosol matrix formed after the mixing. The loading area 20 is used to set up a plurality of liquid storage devices for storing liquid materials, and the liquid material is an aerosol matrix or a component of an aerosol matrix. The pump liquid component 30 is configured to pump the liquid material in at least one liquid storage device into the mixing chamber 10. The atomization component 40 is disposed in the mixing chamber 10, and the atomization component 40 is used to heat the aerosol matrix entering the atomization component 40 from the mixing chamber 10 to generate an aerosol. The switching mechanism 50 is disposed at the connection between the loading area 20 and the pump liquid component 30, and can switch the liquid storage device that is connected to the pump liquid component 30.

[0039] The aerosol matrix may include a base oil and a fragrance, that is, the components of the aerosol matrix may be a base oil or a fragrance. The liquid material may be a base oil or a fragrance, and the base oil and the fragrance may be mixed in the liquid mixing chamber 10 to form a desired aerosol matrix. The liquid material may also be a different aerosol matrix, and different aerosol matrices may be mixed in the liquid mixing chamber 10 to form an aerosol matrix with a new flavor or function. The base oil may be, for example, PG (propylene glycol) / VG (glycerol) in a volume ratio of 4:6, as a base for mixing with other ingredients such as fragrances.

[0040] In this embodiment, the liquid storage device loaded in the loading area 20 can store different liquid materials. When in use, the user can make the mixing chamber 10 have aerosol matrices with different flavors or functions without replacing the liquid storage device, which simplifies the operation of replacing aerosols with different flavors or functions, and has low cost of use. In addition, at least two different liquid materials can be mixed in the mixing chamber 10 at the same time, which can meet the personalized or diversified needs of users. In addition, when at least two different liquid materials are pumped into the mixing chamber 10, these liquid materials can be mixed before atomization to ensure homogeneity. In some embodiments, the switching mechanism 50 can switch the liquid storage device that is connected to the pump liquid component 30, so that the liquid materials in different liquid storage devices can be selectively pumped into the mixing chamber 10. In other embodiments, the pump liquid component 30 can also be provided with a plurality of pipelines, which are respectively connected to different liquid storage devices to pump liquid materials in different liquid storage devices respectively.

[0041] The liquid storage device may include a first liquid storage device 71 and a second liquid storage device 72. The first liquid storage device 71 or the second liquid storage device 72 may be used to store components of aerosol matrix such as base oil and fragrance, or may be used to store aerosol matrix. In this embodiment, the first liquid storage device 71 and the second liquid storage device 72 store different substances respectively, and the number of the first liquid storage device 71 may be one or more, and the number of the second liquid storage device 72 may be multiple, and the volume of the first liquid storage device 71 may be greater than the volume of the second liquid storage device 72; in some other embodiments, the substances, sizes, and quantities stored in the first liquid storage device 71 and the second liquid storage device 72 may be adjusted according to actual needs, without being restricted to the limitations of this embodiment.

[0042] In one embodiment, the atomizing device 1 further comprises a housing assembly 60, which can serve as the outer shell of the atomizing device 1 and can have various chambers formed inside to accommodate the internal structure of the atomizing device 1. The liquid mixing chamber 10 is formed inside the housing assembly 60. Figure 1 As shown, the housing assembly 60 may include a housing upper cover 61 and a liquid mixing chamber bracket 62. The liquid mixing chamber bracket 62 may cooperate with the housing upper cover 61 to form a liquid mixing chamber 10. Figure 2 The mixing chamber support 62 may have a pipeline hole 621, which is disposed beside the mixing chamber 10 for allowing the outlet pipeline 311 in the pump assembly 30 to pass through. Figure 3 As shown, an injection hole 622 is provided on the side wall of the mixing chamber 10 corresponding to the mixing chamber 10 on the mixing chamber bracket 62, and liquid material can be injected into the mixing chamber 10 through the injection hole 622. An air inlet 623 for air to pass through is also provided at the bottom of the mixing chamber bracket 62. When the user inhales, air enters the atomizing assembly 40 from the air inlet 623.

[0043] In one embodiment, a liquid storage device that can be repeatedly injected with liquid materials can be fixed in the loading area 20. Or in one embodiment, a detachable and replaceable liquid storage device can be fixed in the loading area 20. By replacing the liquid storage device, the user's flexibility in freely combining different flavors or functions can be improved, and the diversity of user experience can be enhanced. It can be seen that in this embodiment, the liquid storage device is fixed to the loading area 20 only represents the state during loading, and does not limit its performance of whether to be detached and replaced.

[0044] In one embodiment, the loading area 20 may include a plurality of independent sub-chambers, each of which may be used to accommodate and fix a liquid storage device. The liquid storage devices are respectively arranged in different sub-chambers, and each liquid storage device may be replaced independently, which is relatively flexible and can also ensure that the loading position of the liquid storage device is accurate and stable after loading. To facilitate replacement and free combination, at least some of the sub-chambers may be set to the same size; accordingly, at least some types of liquid materials may be stored by liquid storage devices of uniform specifications to have better versatility, for example, the second liquid storage device 72 for storing spices may adopt uniform specifications.

[0045] In one embodiment, the loading area 20 includes a first sub-chamber 21 and a plurality of second sub-chambers 22. The first sub-chamber 21 is used to set a first liquid storage device 71, the first liquid storage device 71 set in the first sub-chamber 21 is connected to the pump liquid assembly 30, and the first liquid storage device 71 is used to store base oil. The second sub-chamber 22 is used to set a second liquid storage device 72, the second liquid storage device 72 is used to store fragrances, and at least one second liquid storage device 72 is connected to the pump liquid assembly 30. In some embodiments, the connection state between the second liquid storage device 72 and the pump liquid assembly 30 can be controlled by the switching mechanism 50, so that the second liquid storage device 72 connected to the pump liquid assembly 30 can be switched. It can be seen that only a part of the liquid storage devices fixedly accommodated in the loading area 20 can be controlled by the switching mechanism 50; specifically, the first liquid storage device 71 set in the first sub-chamber 21 will not be controlled by the switching mechanism 50.

[0046] The base oil is mainly used to form a smoke effect after being heated, and to adjust the smoking taste, such as the roaring feeling. It is recommended to mix a certain proportion of base oil according to the flavor the user wants to choose. A first sub-chamber 21 that is connected to the pump liquid assembly 30 is provided, which can be used to set a first liquid storage device 71 for storing base oil, which can reduce the number of liquid storage devices that need to be controlled by the switching mechanism 50 and reduce the complexity of the structure or control. Corresponding to the second sub-chamber 22, in actual applications, second liquid storage devices 72 storing different flavors can be selected in different second sub-chambers 22, so that different flavors can be flexibly selected and mixed with the base oil according to needs.

[0047] In one embodiment, the housing assembly 60 further includes a main housing 63 and a base 64. The loading area 20 is formed in the main housing 63. Figure 1 As shown, the size of the loading area 20 can completely accommodate the liquid storage device. After the liquid storage device is installed, the base 64 can be covered to seal and protect the liquid storage device in the housing. In other words, the liquid storage device is detachably arranged in the housing assembly 60.

[0048] See also Figure 4 and Figure 5 ,in, Figure 4 This is a schematic diagram of the bottom of the main housing 63 (i.e., the side away from the housing cover 61), and the liquid storage device can be loaded from the bottom of the main housing 63; Figure 5 It is a schematic diagram from the perspective of the bottom of the main housing 63. In one embodiment, the number of the first sub-chambers 21 is less than the number of the second sub-chambers 22. The more second sub-chambers 22 can be respectively configured with different fragrances to meet the user's more diverse customization needs.

[0049] The second sub-chambers 22 may have the same form, that is, the size and shape are the same. The second liquid storage device 72 may be set to the same specifications, and thus may be set in any second sub-chamber 22. The second liquid storage device 72 of uniform specifications has good versatility and is convenient for users to perform replacement operations.

[0050] In one embodiment, the volume of the first sub-chamber 21 is larger than that of the second sub-chamber 22. The amount of base oil used is larger than that of fragrance, and the first sub-chamber 21 with a larger volume can be provided with a larger first liquid storage device 71, which reduces the number of times the first liquid storage device 71 needs to be replaced or supplemented with base oil, thereby reducing the user's operations.

[0051] In one embodiment, a plurality of second sub-chambers 22 are arranged circumferentially, and the first sub-chamber 21 is located at the center of the area enclosed by each of the second sub-chambers 22 .

[0052] In one embodiment, the loading area 20 includes a plurality of hollow members 631, one end of the hollow member 631 is used to be disposed inside the liquid storage device, and the other end is used to connect with the switching mechanism 50 to transport the liquid material therein. Figure 1 As shown, the hollow member 631 is disposed on the main housing 63, and the hollow member 631 can partially enter the liquid storage device so as to pump out the liquid material therein. Figure 5As shown, the hollow part 631 can be provided corresponding to each sub-chamber. The hollow part inside the hollow part 631 can be used to transport liquid materials. Exemplarily, the hollow part 631 can be needle-shaped, which is convenient for piercing the liquid storage device. The switching mechanism 50 can achieve the effect of controlling whether the liquid storage device corresponding to the hollow part 631 and the pump liquid component 30 are connected by controlling the closed and open states of the port of the hollow part 631. For example, when the switching mechanism 50 closes the end of the hollow part 631 docking with it, the corresponding liquid storage device and the pump liquid component 30 can no longer be connected; on the contrary, when the switching mechanism 50 keeps the end of the hollow part 631 docking with it open, the corresponding liquid storage device and the pump liquid component 30 can be in a state of conduction, and the pump liquid component 30 can pump out the liquid material in the liquid storage device through operation to finally pump it into the mixing liquid chamber 10.

[0053] The depth of the hollow member 631 entering the liquid storage device can be set according to the needs. In this embodiment, the liquid material in the liquid storage device can be filled by positive pressure, that is, the liquid storage device has a pressure greater than the external atmospheric pressure. When the liquid material is pumped out, the pressure in the liquid storage device drives the liquid material to be transported. In other embodiments, the hollow member 631 can also be set to enter the liquid storage device at a deeper depth.

[0054] refer to Figure 6 The pumping liquid assembly 30 may include a pumping liquid element 32 and a pipeline assembly 31, wherein the pumping liquid element 32 may be a device such as an oil pump that can suck liquid and can also pump liquid, and the pipeline assembly 31 serves as a conveying channel for liquid materials. The pipeline assembly 31 of the pumping liquid element 32 includes a liquid outlet pipeline 311, one end of the liquid outlet pipeline 311 is connected to the liquid outlet 321 of the pumping liquid element 32, and the other end is connected to the pipeline hole 621 of the mixing liquid chamber 10, so that the pumping liquid element 32 sucks the liquid materials in the first liquid storage device 71 and the second liquid storage device 72, transfers them into the liquid outlet pipeline 311, and then pumps them into the mixing liquid chamber 10 through the pipeline hole 621. The pumping liquid assembly 30 may be provided with only one liquid outlet pipeline 311, and the liquid materials in the first liquid storage device 71 and the second liquid storage device 72 are all pumped into the mixing liquid chamber 10 through the liquid outlet pipeline 311. In other embodiments, the pump assembly 30 may also be provided with more than one liquid outlet pipeline 311 to achieve separate pumping of different liquid materials. In some embodiments, the liquid materials in the first liquid storage device 71 and the second liquid storage device 72 may be pumped into the liquid mixing chamber 10 in sequence; in other embodiments, they may also be pumped in simultaneously.

[0055] A receiving chamber 632 is formed in the main shell 63, and the receiving chamber 632 may include a pumping element groove 6321 for arranging the pumping element 32. The pumping assembly 30 is arranged in the pumping element groove 6321, and is connected to the mixing chamber 10 and the liquid storage device through the pipeline assembly 31. The receiving chamber 632 in the main shell 63 is used to form an area for accommodating other structures in the atomization device 1, so that these structures are separated from the mixing chamber 10, such as the switching mechanism 50, the pumping assembly 30, etc. The mixing chamber 10 and the receiving chamber 632 are not connected to each other, and the receiving chamber 632 and the loading area 20 are connected to each other. Figure 1 and Figure 3 As shown, the main housing 63 and the liquid mixing chamber bracket 62 are installed to form a receiving chamber 632 therebetween. The liquid mixing chamber bracket 62 may be provided with a positioning member 624 which is inserted into the main housing 63 to ensure the accuracy of the installation position.

[0056] In one embodiment, the switching mechanism 50 may be disposed at the connection between the loading area 20 and the pump assembly 30, that is, the switching mechanism 50 may be located between the loading area 20 and the pipeline of the pump assembly 30, for example, it may be used as a structure for connecting the loading area 20 and the pump assembly 30. The loading area 20 and the pump assembly 30 may be connected and connected, and the switching mechanism 50 may control the connection state between the loading area 20 and the pump assembly 30.

[0057] It should be noted that all liquid storage devices may be controlled by the switching mechanism 50, or only a part of the liquid storage devices may be controlled by the switching mechanism 50. However, the switching mechanism 50 can control at least two liquid storage devices, so as to be able to switch the liquid storage device connected to the pump liquid component 30. In addition, the liquid storage device connected to the pump liquid component 30 may be one, and in some implementations, there may be more than one liquid storage device connected to the pump liquid component 30 at the same time.

[0058] In one embodiment, the switching mechanism 50 includes a movable member 51. Figure 3 and Figure 6 As shown, a through hole 511 is provided on the movable part 51, one end of the through hole 511 is maintained in sealed liquid-conducting communication with the pump liquid assembly 30, and the other end of the through hole 511 is used to communicate with the liquid storage device. The movable part 51 is configured to be movable, and when the movable part 51 moves, the position of the through hole 511 also changes accordingly. The through hole 511 can be connected to different liquid storage devices at different positions, and the liquid storage device connected to the through hole 511 is connected to the pump liquid assembly 30 through the through hole 511, so that the pump liquid assembly 30 can absorb the liquid from the currently connected liquid storage device.

[0059] The pipeline assembly 31 of the pump assembly 30 includes a movable pipeline 312, such as Figure 6As shown, the movable pipeline 312 is connected to the through hole 511 on the movable part 51 and can move with the movable part 51. The other end of the movable pipeline 312 is connected to the pumping element 32. The movable part 51 can move in a translational or rotational manner, wherein the translation or rotation can be performed in a plane at the connection between the loading area 20 and the accommodating cavity 632. Exemplarily, the material of the movable pipeline 312 can be soft and have a certain mobility, so that it can move with the movable part 51.

[0060] Since the movable member 51 can change the liquid storage device connected to the through hole 511, a single movable member 51 can be used for multiple liquid storage devices at the same time, and the liquid storage device that can currently communicate with the pump assembly 30 is determined by controlling the position of its through hole 511. In other words, multiple liquid storage devices can share the movable member 51, which reduces the number of parts in the switching mechanism 50, simplifies the overall structure of the atomization device 1, and is conducive to cost control.

[0061] In one embodiment, the movable member 51 is configured to move in a rotational manner so as to change the position of the through hole 511. Figure 6 and Figure 7 As shown, the rotation center of the movable part 51 is its geometric center, and the second liquid storage devices 72 are circumferentially distributed corresponding to the rotation center of the movable part 51; the distance from the projection of each circumferentially distributed second liquid storage device 72 to the rotation plane of the movable part 51 to the rotation center is the same, and matches the distance from the through hole 511 to the rotation center. Corresponding to the activity mode of the movable part 51, the second liquid storage devices 72 controlled by the switching mechanism 50 are circumferentially distributed around the rotation center. Among them, the distance from the projection of each circumferentially distributed second liquid storage device 72 to the rotation plane of the movable part 51 to the rotation center (hereinafter referred to as the first distance) is the same, and matches the distance from the through hole 511 to the rotation center (hereinafter referred to as the second distance). The movable part 51 rotates so that the through hole 511 can dock with different second liquid storage devices 72. The movable part 51 may be provided with one through hole 511 for conveying liquid, and the second liquid storage device 72 connected to the through hole 511 is in conduction with the pump liquid assembly 30, and the remaining paths between the second liquid storage device 72 and the pump liquid assembly 30 that are not connected can be blocked by the movable part 51. The above-mentioned first distance can be regarded as the distance from the center of the projection of the second liquid storage device 72 to the rotation center, and the first distance can be the same as the second distance or different from the second distance. However, it should be noted that the first distance and the second distance match, that is, the through hole 511 can correspond to the second liquid storage device 72. When the first distance and the second distance are the same, the through hole 511 can be aligned with the center of the second liquid storage device 72; when the first distance and the second distance are different, the through hole 511 is not aligned with the center of the second liquid storage device 72, but is still within the range corresponding to the second liquid storage device 72, and can achieve communication with the second liquid storage device 72.

[0062] By rotating around the geometric center, a single movable part 51 can cover multiple second liquid storage devices 72 distributed circumferentially.
