[0002] Most of the atomization devices on the market are powered by a single lithium battery with a rated voltage of 3.7V. The output power of the atomization device is limited and the sustainability is poor when powered by a single battery.

Second, due to the discharge rate, the boost circuit has limited output power improvement for the atomization device.

DETAILED DESCRIPTION

[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0055] Therefore, the following detailed description of embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the application as claimed, but merely represents selected embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the application.

[0056] It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0057] In the description of the application, it should also be noted that unless otherwise explicitly specified and limited, the terms "set", "mount", "connected", "connected" should be broadly understood, 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 of ordinary skill in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0058] Most of the atomization devices on the market currently use a single lithium battery with a rated voltage of 3.7V for power supply. Single-cell power supply works, and the output power of the atomization device is limited, and the sustainability is poor. In order to realize the power output of the atomization device above 50 watts, the related technology currently increases the high-power boost circuit on the circuit. First, although the boost circuit improves the output power of the atomization device, it is limited by the capacity of the battery, and the continuous working time of the high-power output of the atomization device is very short, which cannot be used continuously. Moreover, the boost circuit will consume part of the energy, so that the circuit and the atomization device will easily heat up during a long smoking process, further shortening the continuous working ability of the atomization device. Second, due to the discharge rate, the boost circuit has limited output power improvement for the atomization device. Therefore, the atomization device products on the market currently cannot meet the needs of heavy smokers.

[0059] To solve the above technical problems, the embodiments of the application provide an atomization device.

[0060] Referring to Figure 1 , Figure 2 As shown in the figure, the embodiments of the application provide an atomization device, which comprises an atomizer 105 for atomizing aerosol substrate and a power supply assembly 100 for supplying power to the atomizer 105; wherein the power supply assembly 100 and the atomizer 105 are electrically connected through an external power supply line 104.

[0061] The power supply assembly 100 of the embodiment of the present application comprises a power supply shell 101 and at least one battery cell 102. The power supply shell 101 is used to define a power supply cavity. The battery cell 102 is arranged in the power supply cavity and used to provide power supply.

[0062] It should be noted that the related art directly integrates the battery cell inside the atomizer 105. Due to the small volume of the atomizer 105, the accommodation space inside the atomizer 105 is relatively small, which leads to a small capacity of the battery cell that can be installed inside the atomizer 105. Therefore, the output power and the continuity of the atomizer 105 are limited by the capacity of the battery cell.

[0063] The embodiment of the present application adds a portable host outside the atomizer 105, increases the installation space of the battery cell through the portable host, and realizes the expansion of the installation space of the battery cell. Therefore, the battery cell 102 can be arranged in the power supply shell 101. It should be noted that the battery capacity of the battery cell 102 is greater than that of the atomizer battery cell 110 installed in the atomizer 105.

[0064] For example, the battery cell 102 can be formed by connecting a plurality of battery cells in series to form a battery cell 102 with a capacity of 10000-20000mAh. For example, the battery cell 102 has five battery cells, each with a capacity of 3000mAh, to form a battery cell 102 with a capacity of 15000mAh. For example, the battery cell 102 has five battery cells, each with a capacity of 2000mAh, to form a battery cell 102 with a capacity of 10000mAh.

[0065] The capacity of the battery cell 102 can be set by those skilled in the art as needed, and no special limitation is made.

[0066] It should be noted that the type of battery cell inside the battery cell 102 can be a lithium ion battery or a lithium polymer battery. The lithium ion battery has high energy density, many charge and discharge cycles, and good safety. The lithium polymer battery has higher energy density and more flexible shape, and is suitable for customized design. It should be noted that the capacity of a single lithium ion battery and a lithium polymer battery is between 2000mAh and 3000mAh under normal circumstances.

[0067] The type of battery cell used inside the battery cell 102 can also be selected by those skilled in the art as needed, and no special limitation is made.

[0068] In some embodiments, the atomization device further comprises a display lamp 116 arranged on the surface of the power supply shell 101 and used to display a state parameter of the battery cell 102.

[0069] The state parameter comprises at least one of the power, the charging state, and the power supply state.

[0070] The display lamp 116 is arranged on the surface of the power supply shell 101, so that the user can intuitively understand the use state of the power supply assembly 100, and the convenience of using the power supply assembly 100 is improved.

[0071] In some embodiments, the atomizer 105 of the embodiment of the present application comprises:

[0072] The heating element 109 is configured to atomize the aerosol substrate.

[0073] The circuit board 108 is electrically connected to the heating element 109 and is configured to control the heating element 109 to heat and atomize.

[0074] The power supply interface 103 is arranged on the circuit board 108 and is configured to transmit current.

[0075] The power supply interface 103 is configured to be electrically connected to the external power supply line 104 to receive current from the power supply assembly 100.

[0076] It should be noted that the power supply interface 103 is arranged on the circuit board 108, so that the circuit board 108 can supply power to the heating element 109 after the external power supply line 104 is connected to the power supply interface 103, and the heating element 109 can heat the aerosol substrate at a high power.

[0077] The specific structure of the power supply interface 103 can be set by those skilled in the art as needed, and no special limitation is made. For example, the power supply interface 103 is a direct current socket. For example, the power supply interface 103 is a USB Type-C. It should be noted that the power supply interface 103 can also be set as a magnetic interface as needed.

[0078] The atomization device provided by the embodiment of the present application can output high voltage and has high capacity and high current output discharge capability.

[0079] Referring to Figure 1 , Figure 2 The embodiment of the present application provides an atomization device, which comprises a power supply assembly 100 and an atomizer 105. The power supply assembly 100 of the embodiment of the present application comprises a power supply shell 101 and an electric core 102 arranged in the power supply shell 101. Compared with the small electric core power supply in the related art, the embodiment of the present application forms an external large-power power supply assembly through the power supply shell 101 and the electric core 102, which can supply power to the atomizer 105.

[0080] Compared with the related art, the embodiment of the present application can greatly improve the output power of the atomizer 105, so that the atomizer 105 works at a power of 50 watts or more. In addition, the embodiment of the present application can ensure the continuous output capability of the atomizer 105 in the high-power working mode, effectively improving the continuous working capability of the atomization device.

[0081] Referring to Figure 3 , Figure 4 As an optional implementation, the atomization device further includes: a first connector 111, which is electrically connected with the first end of the external power line 104 and is used for current transmission.

[0082] The first connector 111 is configured to be matched with the power supply interface 103 to supply power to the atomizer 105.

[0083] The atomization device of the embodiment of the present application further includes: an output interface 112, which is arranged on the power supply shell 101 and is used for outputting current.

[0084] A second connector, which is electrically connected with the second end of the external power line 104 and is used for current transmission.

[0085] The second connector is configured to be matched with the output interface 112 to supply power to the atomizer 105.

[0086] It should be noted that the first end of the external power line 104 can be freely plugged with the power supply interface 103 through the arrangement of the first connector 111, and the second end of the external power line 104 can be freely plugged with the output interface 112 through the arrangement of the second connector. The above arrangement of the embodiment of the present application not only facilitates the user to quickly operate when charging, but also facilitates the user to quickly store the external power line 104.

[0087] As an optional implementation, the power supply assembly 100 further includes:

[0088] A control circuit board, which is electrically connected with the battery cell 102 and is used for controlling the input of the battery cell.

[0089] An input interface 113, which is electrically connected with the control circuit board and is used for charging the power supply assembly 100.

[0090] The embodiment of the present application is provided with the input interface 113 for charging the battery cell 102 on the power supply shell 101, and the battery cell 102 can be charged through the input interface 113 after the battery cell 102 is depleted.

[0091] The input interface 113 and the output interface 112 can be arranged on the same side of the power supply shell 101. It should be noted that the input interface 113 and the output interface 112 can also be arranged on adjacent two sides according to the needs of those skilled in the art.

[0092] As an optional embodiment, the power supply shell 101 of the embodiment of the application is provided with an opening, and the opening is in communication with the power supply cavity.

[0093] The battery cell 102 is configured to be taken out of or put into the power supply cavity through the opening.

[0094] It should be noted that the battery cell 102 in the power supply cavity can be quickly replaced by the opening.

[0095] The atomizer 105 of the embodiment of the application comprises an atomizer shell 106, a liquid storage cavity 107 and a circuit board 108 arranged in the atomizer shell 106; the liquid storage cavity 107 stores the aerosol substrate by arranging a cotton core, and the liquid storage cavity 107 is provided with a heating element 109 in contact with the aerosol substrate; the heating element 109 is electrically connected with the circuit board 108, and the circuit board 108 is electrically connected with the battery cell 102 through the power supply interface 103.

[0096] It should be noted that the embodiment of the application comprises the atomizer shell 106, which can accommodate and protect the liquid storage cavity 107 and the circuit board 108. The liquid storage cavity 107 provided by the embodiment of the application can store the aerosol substrate, and the heating element 109 arranged on the liquid storage cavity 107 can heat the aerosol substrate in the liquid storage cavity 107.

[0097] It should be noted that the heating element 109 can be arranged on the inner wall of the liquid storage cavity 107 to heat the aerosol substrate, or the heating element 109 can be arranged to be inserted into the aerosol substrate in the liquid storage cavity 107. The heating element 109 needs to be in direct contact with the aerosol substrate.

[0098] In some embodiments, the heating element 109 can be made of any one of nickel-chromium alloy, kanthal alloy, titanium alloy and stainless steel. It should be noted that the specific model and material of the heating element 109 can be selected according to the needs of those skilled in the art, and no special limitation is made. It should be noted that the heating of the aerosol substrate by the heating element 109 is the core process of the operation of the atomization device. By selecting appropriate materials for the heating element 109, adjusting the power setting and regular maintenance, the performance and safety of the atomization device can be ensured. Different materials of the heating element 109 have different resistance values, which affect the heating speed and temperature. In addition, the wire diameter and length of the heating element 109 also affect the resistance value.

[0099] The heating element 109 generates resistance heat under the action of the battery cell 102, and reaches a set temperature. The cotton core in the liquid storage cavity 107 absorbs the aerosol substrate. The heat of the heating element 109 is transferred to the aerosol substrate by heat conduction, so that the aerosol substrate stored on the cotton core is vaporized at high temperature to form steam.

[0100] Referring to Figure 4 As an optional embodiment, the atomizer shell 106 is provided with an atomizer battery cell 110, which is electrically connected with the circuit board 108 and used to supply power to the heating element 109.

[0101] In some embodiments, the atomizer battery cell 110 is arranged in the atomizer shell 106, and the atomizer battery cell 110 is used as a first power supply component to supply power to the heating element 109. Since the capacity of the atomizer battery cell 110 is small, it cannot support long-time and large output. The battery cell 102 is used to charge the atomizer battery cell 110, or the battery cell 102 is used as a second power supply component to supply power to the heating element 109.

[0102] Specifically, when the external power supply line 104 is connected with the power supply interface 103 of the atomizer 105, the battery cell 102 is used to supply power to the heating element 109. When the external power supply line 104 is disconnected with the power supply interface 103 of the atomizer 105, the atomizer battery cell 110 is used to supply power to the heating element 109.

[0103] That is to say, the atomizer 105 can work at a large power and for a long time when the battery cell 102 supplies power to the heating element 109 through the connection of the external power supply line 104 and the power supply interface 103.

[0104] The atomizer 105 can work at a small power for a long time when the atomizer battery cell 110 supplies power to the heating element 109 through the disconnection of the external power supply line 104 and the power supply interface 103. At this time, the power supply component 100 does not need to be connected, so that the use of the atomizer 105 is more flexible and is not limited by the external power supply line 104.

[0105] In some embodiments, the atomization device further comprises:

[0106] A detection circuit module is configured to acquire a connection signal of the atomizer 105 and the external power supply line 104. The connection signal includes two cases that the atomizer 105 is connected with the external power supply line 104 or not connected with the external power supply line 104.

[0107] A power switching module is configured to switch the atomizer battery cell 110 or the power supply component 100 to supply power to the atomizer 105 according to the connection signal acquired by the detection circuit module.

[0108] The charging circuit module is used for controlling the power supply assembly 100 to charge the atomizer battery 110.

[0109] Referring to Figure 5 When the external power supply line 104 of the power supply assembly 100 is not connected with the atomizer 105, the atomizer battery positive electrode 117 is conducted with the load access end 118 of the atomizer 105, at this time, the atomizer battery 110 supplies power to the load.

[0110] When the external power supply line 104 of the power supply assembly 100 is connected with the atomizer 105, the high level is input from the power supply assembly access end 119, and after the high level passes through a pair of common cathode Schottky diodes, the base of the P-type MOS tube is pulled high, so that the P-type MOS tube is closed, thereby closing the power supply from the atomizer battery positive electrode 117 to the load, and directly and automatically switching to the power supply from the power supply assembly 100.

[0111] Referring to Figure 6 As shown in the figure, the power supply assembly 100 is connected with the power supply interface 103 through the external power supply line 104, and the power supply assembly 100 can charge the atomizer battery 110 and supply power to the heating element 109. In addition, the power supply interface 103 can also be used as an interface for software upgrading.

[0112] When the atomizer 105 is not connected with the external power supply line 104, the DET USB signal is 0V. When the external power supply line 104 is connected with the power supply interface 103, the DET USB signal is a high level signal of 2.5V. The high level signal is output to the central processing unit on the circuit board 108, and the central processing unit makes corresponding program instructions according to the program, so that the detection circuit module realizes the plug detection function of the external power supply line 104 and obtains the connection signal of the atomizer 105 and the external power supply line 104.

[0113] In Figure 6 , Figure 7 , VCC USB5V is the power supply signal provided by the power supply assembly 100 through the external power supply line 104; VCC BAT is the power supply signal provided by the atomizer battery 110; F OUT is the power supply directly provided for the heating element 109.

[0114] When the atomizer 105 is not connected with the external power supply line 104, that is, the user uses the atomizer 105 alone, the DET USB signal is 0V, at this time, the driving circuit power supply of the heating element 109 is provided by the VCC BAT power supply signal, that is, the power supply provided by the atomizer battery 110. The central processing unit modulates the duty cycle of VCC BAT through the MCU PWM signal, drives the P-type field effect tube Q17, so that the power supply voltage is modulated into the power supply voltage F OUT required by the heating element 109. The specific size of the example F OUT is 3.2V.

[0115] When the atomizer 105 is connected to the external power line 104 for use, the DET USB signal is a high-level signal and is output to the central processor, at which time the central processor of the atomizer 105 can output high power according to the gear requirement.

[0116] As can be seen from Figure 7 , since the VCC USB5V is connected to the base of the P-type field effect tube Q16, when the VCC USB5V is a 5V high level, the base of the P-type field effect tube Q16 will be in a high level state, thereby closing the conduction function of the P-type field effect tube Q16, and the V POWER power supply is automatically switched from VCC_BAT to VCC_USB5V power supply.

[0117] Referring to Figure 1 , as an optional embodiment, the atomization device of the embodiment of the application further comprises a fastener 114, which is arranged on the surface of the power supply shell 101. The fastener 114 can fix the power supply assembly 100 to the user's clothes or bag by hanging.

[0118] The user can fix the power supply assembly 100 on the waist, shoulder, clothes, etc. through the fastener 114, which is convenient for the user to carry.

[0119] Referring to Figure 1 , as an optional embodiment, the atomizer 105 is provided with a suction nozzle 115, and the suction nozzle 115 and the power supply interface 103 are arranged on the opposite sides of the atomizer 105.

[0120] The suction nozzle 115 and the power supply interface 103 are arranged on the opposite sides of the atomizer 105, which is convenient for the user to use the atomization device through the suction nozzle 115 when the external power line 104 is connected to the power supply interface 103.

[0121] In some embodiments, the power supply assembly 100 is provided with a winding roller, and the external power line 104 is wound on the winding roller. The winding roller is driven to rotate to make the external power line 104 extend or wind back.

[0122] The above arrangement is convenient for quickly storing the external power line 104 and facilitates the use of the user, which can greatly improve the convenience. In addition, the winding arrangement of the external power line 104 does not occupy too much space.

[0123] The above only describes the preferred embodiments of the application and is not used to limit the application. For those skilled in the art, the application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
