[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] This application provides an atomization device. Figure 1-Figure 4 , the atomizing device 100 may include an atomizer 80 and an atomizing host 90. The atomizer 80 and the atomizing host 90 may be fixedly connected or detachably connected. Among them, the atomizer 80 includes a shell assembly 10 and an atomizing assembly 20, and the atomizing host 90 includes a control assembly 30. The shell assembly 10 has a receiving chamber 14, and the atomizing assembly 20 is installed in the receiving chamber 14. The atomizing assembly 20 is provided with an oil storage chamber 24, and the oil storage chamber 24 stores an atomizing matrix, and the atomizing assembly 20 is used to atomize the atomizing matrix into an aerosol. The control assembly 30 is used to control the working state of the atomizing assembly 20. For example, the control assembly 30 can control the atomizing assembly 20 to heat the atomizing matrix to generate an aerosol or stop heating according to the user's suction action.

[0033] like Figure 1 , Figure 2As shown, the housing assembly 10 includes a first housing 11, a second housing 12 and a nozzle housing 13. The first housing 11 has an inner space, and the second housing 12 and the nozzle housing 13 are enclosed with the first housing 11 to form a receiving cavity 14, so that the number of parts of the housing assembly 10 is small, the assembly process of the housing assembly 10 can be simplified, and the assembly efficiency can be improved. The atomizing device 100 has a length direction. For example, the length direction can be Figure 3 The first shell 11 is provided with a first mounting hole 1121 on one side perpendicular to the length direction, and the second shell 12 is installed in the first mounting hole 1121. The first shell 11 is provided with a second mounting hole 1112 at one end in the length direction, and the nozzle shell 13 is installed in the second mounting hole 1112. Optionally, the connection between the second shell 12, the nozzle shell 13 and the first shell 11 can be bonding, clamping or threaded connection. The nozzle shell 13 can be used for the user to inhale, and the nozzle shell 13 is connected to the atomizer assembly 20 so that the aerosol generated by the atomization of the atomizer assembly 20 can reach one end for the user to inhale.

[0034] Generally speaking, in order to ensure the overall appearance of the shell assembly 10, the area of ​​the bottom of the shell assembly 10 is usually smaller than the area of ​​the side of the shell assembly 10. For example, the area of ​​the bottom of the first shell 11 is set to be smaller than the area of ​​the side of the first shell 11. The first mounting hole 1121 is opened on the side of the first shell 11 perpendicular to the length direction, and the components in the accommodating cavity 14 can be installed through the first mounting hole 1121. Compared with the first mounting hole 1121 opened in other parts, such as the end (specifically, the bottom) of the first shell 11 in the length direction, the first mounting hole 1121 can have a relatively large opening area, thereby providing a relatively large operating space, which is conducive to assembly operations and can further improve assembly efficiency.

[0035] See also Figure 2 , Figure 3, the atomization assembly 20 may include an atomization core 21 and an oil cup 22. The oil cup 22 has an oil storage chamber 24, and the atomization core 21 is installed in the oil storage chamber 24, and the oil storage chamber 24 is used to store the atomization matrix. The atomization matrix can be stored in the oil storage chamber 24 in the form of a liquid, or it can be stored with the help of a storage medium. For example, the atomization assembly 20 also includes an oil storage member 23, the oil storage member 23 is filled in the oil storage chamber 24, the oil storage member 23 is wrapped outside the atomization core 21, the oil storage member 23 is a porous medium, such as fiber cotton, and the oil storage member 23 can adsorb the atomization matrix, thereby storing the atomization matrix in the oil storage chamber 24. Optionally, the oil cup 22 includes an oil cup shell 221 and an oil cup base 222, and the oil cup shell 221 and the oil cup base 222 are surrounded to form an oil storage chamber 24. The atomization core 21 may include a heating element 211, a liquid guide 212 and an atomization tube 213. The function of the liquid guide 212 is to transfer the atomized matrix to the heating element 211, and the function of the heating element 211 is to generate heat by electricity, thereby heating the atomized matrix to atomize it. Exemplarily, the liquid guide 212 is a cotton liquid guide, and the liquid guide 212 is wrapped around the outer periphery of the heating element 211. The liquid guide 212 is at least partially accommodated in the atomizing tube 213, so that the heating element 211, the liquid guide 212 and the atomizing tube 213 form a relatively independent module, and then assembled into the oil storage chamber 24 through the atomizing tube 213, such as the atomizing tube 213 is installed on the oil cup base 222, so as to realize the modular assembly of the atomizing core 21, which can improve production efficiency.

[0036] like Figure 2-Figure 4 As shown, the control assembly 30 may include a battery 31, a control circuit board 32, an airflow sensor 33, a bracket 34 and a base 35 installed in the accommodating chamber 14. The battery 31 is used to provide electrical energy for the atomizing device 100 when it is working. The airflow sensor 33 is installed on the control circuit board 32, the bracket 34 is covered on the airflow sensor 33, the bracket 34 is inserted into the oil cup base 222, the base 35 is installed on the side of the control circuit board 32 away from the airflow sensor 33, and the base 35 is connected to the bracket 34, so that the control circuit board 32, the airflow sensor 33, the bracket 34 and the base 35 form a relatively independent module, realize the modular assembly of components, and improve production efficiency. The airflow sensor 33 is configured to control the electrical connection conduction state between the atomizing assembly 20 and the battery 31 according to the user's suction action. Specifically, when the user inhales through the nozzle shell 13, the airflow sensor 33 senses the change in airflow, and the airflow sensor 33 controls the atomization component 20 to be connected to the battery 31, and the atomization component 20 can heat the atomization matrix to generate aerosol; when the user stops inhaling, the airflow sensor 33 does not sense the change in airflow within a preset time period, and the airflow sensor 33 controls the atomization component 20 to be disconnected from the battery 31, and the atomization component 20 stops heating.

[0037] Please continue reading Figure 2-Figure 4, the control assembly 30 also includes an air regulating member 36 and a control key 37. The air regulating member 36 is slidably disposed on the base 35. The oil cup 22 is provided with a first air inlet hole 2222, and the bracket 34 is provided with a second air inlet hole 3413, and the second air inlet hole 3413 is connected to the first air inlet hole 2222. An air regulating hole 361 is provided on the air regulating member 36. When the air regulating member 36 slides on the base 35, the connection area between the second air inlet hole 3413 and the air regulating hole 361 can be changed, thereby adjusting the suction resistance of the atomizing device 100, so that the user can experience different suction resistances. A first sealing member 39 can be provided between the bracket 34 and the air regulating member 36. The first sealing member 39 is sleeved on the bracket 34 to enhance the air tightness of the connection between the bracket 34 and the air regulating member 36. The control key 37 is installed on the housing assembly 10, such as installed on the second housing 12, so that the user can control the atomizing device 100 through the control key 37. For example, the user can turn on or off the atomizing device 100 through the control key 37 , or set the heating mode of the atomizing device 100 through the control key 37 , such as setting the atomizing device 100 to heat at normal power or high power.

[0038] like Figure 2-Figure 4 As shown, an oil absorbing member 38 is mounted on the bracket 34, and the oil absorbing member 38 is used to absorb the atomized matrix leaking out of the atomizing assembly 20, so as to prevent the atomized matrix from leaking. The oil absorbing member 38 is a porous medium, such as fiber cotton.

[0039] See also Figure 2-Figure 4 , the atomizing device 100 may further include a display assembly 40, a second sealing member 50, a liquid absorbing member 60 and a shielding member 70. The display assembly 40 is installed in the accommodating chamber 14, and the display assembly 40 is used to display information of the atomizing device 100. Exemplarily, the information displayed by the display assembly 40 may be one or more of the power information, heating mode, heating power, atomizing matrix inventory and brand logo of the atomizing device 100. The display assembly 40 may include a display screen 41 and a display circuit board 42, the display screen 41 is electrically connected to the display circuit board 42, and the display circuit board 42 is used to control the information display of the display screen 41. The display screen 41 may be installed on the display circuit board 42. A display area 1211 is provided on the second housing 12, and the display assembly 40 is arranged adjacent to the second housing 12, and the information displayed by the display assembly 40 is visible through the display area 1211.

[0040] The second sealing member 50, the liquid absorbing member 60 and the shielding member 70 are installed between the atomizing assembly 20 and the nozzle housing 13. The second sealing member 50 is used to seal the oil cup 22 to prevent leakage of the atomized matrix in the oil cup 22. The liquid absorbing member 60 is used to absorb condensed liquid in the aerosol to improve the taste of the aerosol. The shielding member 70 is configured to be opaque. When the nozzle housing 13 is made of a transparent material, the shielding member 70 can prevent the user from observing the liquid absorbing member 60 through the nozzle housing 13 to prevent the liquid absorbing member 60 from changing color after absorbing condensed liquid or atomized matrix and affecting the appearance of the product.

[0041] See also Figure 5-Figure 9 , the heating element 211 includes a heating portion 2111 and a pin 2112. The heating portion 2111 is used to heat the atomized matrix to generate an aerosol, and the pin 2112 is used for the electrical connection between the heating portion 2111 and an external power source. The external power source refers to a power source arranged outside the heating element 211. For example, the heating portion 2111 can be electrically connected to the battery 31 installed in the accommodating chamber 14 through the pin 2112, thereby providing the heating portion 2111 with electrical energy for operation. The number of heating portions 2111 is at least three. For example, the number of heating portions 2111 is 3, 4 or more. At least three heating portions 2111 are arranged in parallel. At least three heating portions 2111 are arranged to heat the atomized matrix independently or in combination, so that the heating power of the heating portion 211 can be controlled by the heating portion 2111 working independently or in combination. The heating portion 211 has a variety of heating modes to meet the different usage requirements of users. The pin 2112 includes at least one common pin and at least three independent pins. Among them, the common pin is used to establish an electrical connection with an electrode having a first polarity, and the independent pin is used to establish an electrical connection with an electrode having a second polarity. The first polarity is one of the negative electrode and the positive electrode, and the second polarity is the other of the negative electrode and the positive electrode. Each independent pin is electrically connected to a heating part 2111. The common pin is electrically connected to at least two heating parts 2111, so that some heating parts 2111 share one pin, which can reduce the number of pins and facilitate the electrical connection between the heating element 211 and the external power supply.

[0042] like Fig.10 As shown, the control circuit board 32 includes at least one first electrode 321A with a first polarity and at least three second electrodes 321B with a second polarity, the first electrode 321A is used to establish an electrical connection with a common pin, and the second electrode 321B is used to establish an electrical connection with an independent pin. The first electrode 321A is electrically connected to one of the negative electrode and the positive electrode of the battery 31, and the second electrode 321B is electrically connected to the other of the negative electrode and the positive electrode of the battery 31, so as to provide electrical energy for the heating part 2111 to work.

[0043] Optionally, the first polarity is the negative pole, and the second polarity is the positive pole. That is, the common pin is electrically connected to the negative pole, and the independent pin is electrically connected to the positive pole. According to the simulation test results, the electric power of the positive pole of any heating part 2111 is greater than the electric power of the negative pole, and the carbon deposition phenomenon near the positive pole is much more obvious than that of the negative pole. Therefore, the shared negative pole can reduce the carbon deposition of the heating element 211. Since the multiple heating parts 2111 of this embodiment can be switched, the positive pole part with higher electric power shortens the total use time by switching, thereby extending the service life of the heating element 211.

[0044] The more the number of heating parts 2111, the more heating power formed by the independent or combined operation of the heating parts 2111, and accordingly, the more heating modes that the heating element 211 can select, but it will increase the difficulty of preparing the heating element 211, and increase the number of pins 2112, which is not conducive to the electrical connection between the heating element 211 and the external power supply. Optionally, the number of heating parts 2111 is 3, and the heating part 2111 includes a first heating part 2111A, a second heating part 2111B, and a third heating part 2111C, which can not only make the heating element 211 have more heating modes, but also reduce the difficulty of preparing the heating element 211, and the number of pins 2112 will not be too many, which is convenient for the electrical connection between the heating element 211 and the external power supply. The independent pins include a first independent pin 2112A, a second independent pin 2112B, and a third independent pin 2112C that are electrically connected to the first heating part 2111A, the second heating part 2111B, and the third heating part 2111C, respectively. There is one common pin, and one common pin 2112D is electrically connected to the first heating part 2111A, the second heating part 2111B and the third heating part 2111C. The first heating part 2111A, the second heating part 2111B and the third heating part 2111C share one common pin 2112D. Under the condition that the three heating parts 2111 can heat the atomized matrix independently or in combination, the number of pins 2112 is minimized. At this time, the number of pins 2112 is four, which facilitates the electrical connection between the heating element 211 and the external power supply.

[0045] Optionally, the atomizing host 90 is configured to selectively start any one of the heating units 2111, and not start the other heating units 2111. In this way, the three heating units can selectively heat the atomized substrate alternately, reducing the cumulative heating time of a single heating unit, reducing the probability of a single heating unit failing, and thus increasing the service life of the heating element 211.

[0046] The resistance values ​​of the first heating part 2111A, the second heating part 2111B and the third heating part 2111C are R1, R2 and R3 respectively. Optionally, R1, R2 and R3 are set to be equal. When one of the three heating parts 2111 works independently, the atomized matrix is ​​heated with the first heating power P1; when any two of the three heating parts 2111 work in combination, the atomized matrix is ​​heated with the second heating power P2; when the three heating parts 2111 work simultaneously, the atomized matrix is ​​heated with the third heating power P3; wherein P3 is greater than P2, and P2 is greater than P1, so that the heating element 211 has three heating modes, which can meet the different usage requirements of users. When R1, R2 and R3 are equal, the first heating part 2111A, the second heating part 2111B and the third heating part 2111C can adopt the same structure, which is conducive to simplifying the preparation process of the heating part 2111.

[0047] Optionally, R1<R2, and R1<R3. When the first heating part 2111A works independently, its heating power is greater than the heating power of the second heating part 2111B and the third heating part 2111C when they work independently, and at least one heating mode is added relative to the equality of R1, R2 and R3; when the first heating part 2111A works in combination with one of the second heating part 2111B and the third heating part 2111C, relative to the equality of R1, R2 and R3, its combined heating power is greater than the combined heating power of the second heating part 2111B and the third heating part 2111C, and at least one heating mode is added. By setting R1 to be greater than R2 and R3, the heating element 211 can have more optional heating modes to meet the different usage requirements of users.

[0048] Optionally, when R1<R2, and R1<R3, the atomizer host 90 is configured to selectively start the second heating part 2111B and the third heating part 2111C, and the first heating part 2111A is not started. With such a configuration, the heating element 211 can have a low-power heating mode in which the second heating part 2111B or the third heating part 2111C works independently, a medium-power heating mode in which the first heating part 2111A works independently, and a high-power heating mode in which the second heating part 2111B and the third heating part 2111C work in combination, forming a heating mode in which three heating powers of low, medium and high change in gradient. The first heating part 2111A with a relatively small resistance value does not work in combination with the other two heating parts, which can prevent the high-power heating part from participating in the combined work, resulting in a sudden change in heating power and affecting the taste.

[0049] It should be noted that in actual products, the specified power cannot be achieved by arbitrarily setting the resistance values ​​of R1, R2, and R3. The reason is that in the field of atomization devices, the resistance values ​​of materials that can be used as heating parts are often within a fixed range. Some materials can achieve lower resistance values, but considering their service life, cost, safety regulations, etc., they cannot be used in the field of atomization devices. That is, this embodiment uses three heating parts with similar resistance values ​​to achieve a wide range of heating power and continuous power adjustment.

[0050] Optionally, R1, R2 and R3 are set to be unequal. When the three heating parts 2111 work independently, the atomized substrate is heated with three different heating powers; when any two of the three heating parts 2111 work in combination, the atomized substrate is heated with another three different heating powers; when the three heating parts 2111 work simultaneously, the atomized substrate is heated with another heating power; thus, the heating element 211 has seven heating modes, and the heating element 211 has more selectable heating modes, which can meet the different usage requirements of users.

[0051] In one embodiment, R1<R2≤R3. Among them, the heating power of the second heating part 2111B and the third heating part 2111C is relatively low, which can correspond to the low-power state of the atomization device 100. Generally speaking, the low-power state is a heating state in which the atomization device 100 is used for a relatively long time, and the service life of the heating element 211 in the low-power state is relatively high. By setting R2≤R3, the heating power of the second heating part 2111B and the third heating part 2111C is similar when working independently. Under the condition of ensuring that the heating power does not change too much, the two can work in rotation, reducing the cumulative heating time of a single heating part, reducing the probability of failure of a single heating part, and thus increasing the service life of the heating element 211 in the low-power state.

[0052] In one embodiment, R2 and R3 are greater than or equal to 0.7 ohms and less than or equal to 1.1 ohms, and R1 is less than 0.7 ohms and greater than or equal to 0.5 ohms. Exemplarily, R2 and R3 are 0.7 ohms, 0.8 ohms, 0.9 ohms, 1.0 ohms or 1.1 ohms, etc., and R1 is 0.5 ohms, 0.55 ohms, 0.6 ohms, 0.65 ohms or 0.69 ohms, etc., which are not specifically limited here. In this way, under the common voltage conditions of the power supply, such as the voltage of 3.4 volts, the heating power of the first heating part 2111A can be approximately 15 watts, and the heating power of the second heating part 2111B and the third heating part 2111C can be approximately 12 watts, which can not only meet the heating power requirements of the atomized matrix, but also save energy consumption and improve the endurance of the atomizing device 100.

[0053] In one embodiment, the heating portion 2111 is in a long strip structure. For example, the heating portion 2111 is made of metal wire, and the heating portion 2111 can be attached to a porous ceramic, such as Fig. 9 shown.

[0054] In one embodiment, if Figure 5-Figure 8 As shown, the first heating part 2111A, the second heating part 2111B and the third heating part 2111C are all in a mesh shape. The heating part 2111 is arranged in a mesh shape so that the heating part 2111 has a larger surface area. When the liquid guide 212 is wrapped around the outer periphery of the heating part 211, the contact area between the heating part 2111 and the liquid guide 212 is larger, which can improve the atomization efficiency.

[0055] In one embodiment, the heating element 211 has a length direction. For example, the length direction may be Figure 3 The Z-axis direction in . Optionally, Fig. 9 As shown, the first heating part 2111A, the second heating part 2111B and the third heating part 2111C are arranged at intervals along the length direction. Alternatively, the second heating part 2111B and the third heating part 2111C are arranged at intervals on the same side of the common pin 2112D, and the first heating part 2111A is arranged on the other side of the common pin 2112D. For example, the second heating part 2111B and the third heating part 2111C are connected to the same side of the first heating part 2111A perpendicular to the length direction, and the second heating part 2111B and the third heating part 2111C are arranged at intervals along the length direction, which can increase the size of the heating part 2111 in the direction perpendicular to the length direction, so as to facilitate adaptation with the liquid guide 212, so as to better support the liquid guide 212, such as supporting the cotton liquid guide. In addition, since the resistance value of the heating part 2111 is inversely proportional to the area of ​​the heating part 2111, when R1<R2≤R3, the area of ​​the first heating part 2111A is the largest. The first heating part 2111A is placed alone on one side, and the second heating part 2111B and the third heating part 2111C are placed side by side on the other side. The first heating part 2111A, the second heating part 2111B and the third heating part 2111C can be connected to form a more regular shape, thereby facilitating the processing of the heating part 2111.

[0056] See also Figure 5-Figure 8, the common pin 2112D is connected to the connection between the second heating part 2111B and the third heating part 2111C and the first heating part 2111A, and the first independent pin 2112A, the second independent pin 2112B and the third independent pin 2112C are respectively connected to the other side of the first heating part 2111A, the second heating part 2111B and the third heating part 2111C away from the connection. Among them, the common pin 2112D can be electrically connected to one of the positive and negative poles of the external power supply, and the first independent pin 2112A, the second independent pin 2112B and the third independent pin 2112C can be electrically connected to the other of the positive and negative poles of the external power supply. The common pin 2112D is set at the connection of multiple heating parts 2111, and the other pins are set on the side of the heating part 2111 away from the connection, so that the pins 2112 can be distributed more dispersedly in space, which is convenient for the arrangement of the pins 2112.

[0057] In one embodiment, the second heating part 2111B and the third heating part 2111C are connected to the first heating part 2111A as an integral part, so that the heating part 2111 can be integrally processed and formed, thereby simplifying the processing and preparation process of the heating part 2111, thereby reducing production costs.

[0058] In one embodiment, the integrated part is in the form of a sheet. For example, the heating portion 2111 can be attached to a sheet of fiber cotton or porous ceramic. By setting the integrated part in the form of a sheet, the size of the atomizer core 21 in the direction perpendicular to the length can be reduced, making it easier for the atomizer core 21 to fit the housing assembly 10, which is wide and flat in appearance, to meet the personalized needs of users.

[0059] In one embodiment, the one-piece is in the shape of a hollow cylinder curled toward each other. Specifically, the first heating part 2111A is a group, the second heating part 2111B and the third heating part 2111C are another group, and the two groups are curled toward each other into a hollow cylinder. Exemplarily, the one-piece can be in the shape of a hollow cylinder, and the liquid guiding part 212 is wrapped around the outer periphery of the heating part 211, and the heating part 211 can provide good support for the liquid guiding part 212 to prevent the liquid guiding part 212 from deforming during the assembly process and affecting the taste consistency of the product. On the outer peripheral surface of the one-piece, the area of ​​the second heating part 2111B is equal to the area of ​​the third heating part 2111C, and the area of ​​the first heating part 2111A is larger than the area of ​​the second heating part 2111B and the third heating part 2111C. By setting the area of ​​the second heating portion 2111B to be equal to the area of ​​the third heating portion 2111C, and both being smaller than the area of ​​the first heating portion 2111A, it is possible to achieve R1 being smaller than R2 and R3, and R2 being equal to R3 under the condition that the structure of the heating portion 2111 (such as the opening rate, cross-sectional thickness, etc.) is the same, so that the shape of the integrated part is more regular and the processing and preparation process of the heating portion 2111 is simplified.

[0060] In one embodiment, the heating element 211 includes a connecting portion 2113. On the outer peripheral surface of the integral part, one side of the connecting portion 2113 is connected to the second heating portion 2111B, and the other side of the connecting portion 2113 extends toward the first heating portion 2111A. The second independent pin 2112B is connected to the other side of the connecting portion 2113. The first independent pin 2112A, the second independent pin 2112B, and the third independent pin 2112C are arranged at intervals in the circumferential direction of the integral part. By providing the connecting portion 2113, under the condition that the area of ​​the second heating portion 2111B is equal to the area of ​​the third heating portion 2111C, the connecting portion between the second independent pin 2112B and the second heating portion 2111B is extended outward, so that the second independent pin 2112B can avoid the first independent pin 2112A, thereby facilitating the arrangement of the pins 2112.
