Background Technology

[0002] With increasing public awareness of health, the idea that "smoking is harmful to health" has become widely ingrained in people's minds. Heated cigarettes, which use heating devices to generate aerosols at relatively low temperatures, significantly reduce harmful substances in tobacco and are increasingly accepted by consumers. However, current heated cigarette devices all use built-in power sources (batteries), and their performance and user experience are limited by the characteristics of battery technology, which affects their suitability in different climates and application scenarios. Summary of the Invention

[0003] This invention provides a cigarette heating device without a built-in power supply and its dedicated power supply, in order to solve the problem that the performance and user experience of cigarette heating devices with built-in power supplies are limited.

[0005] The appliance housing has an insertion hole.

[0006] A heating cavity is located inside the appliance housing and is coaxially arranged with the insertion hole, and a heating element is disposed therein;

[0007] The appliance main control board is disposed inside the appliance housing, and the heating element is electrically connected to the appliance main control board;

[0008] An input / output unit is disposed on the appliance housing and connected to the appliance main control board, and is used to control the start and stop of the heated cigarette appliance;

[0009] At least one power interface for connecting to an external power source is provided on the appliance housing and is electrically connected to the appliance main control board.

[0010] Furthermore, it includes a USB power interface and a pin-type power interface.

[0011] Furthermore, a magnet is provided inside the housing of the device and at its bottom.

[0012] Furthermore, the heating cavity includes:

[0013] The cavity has its two ends abutting against the top and bottom of the device housing, respectively, and is coaxial with the insertion hole;

[0014] A flat wall with a central opening is positioned between the two ends of the cavity, dividing the cavity into an aerosol-generating insertion cavity and a component sealing cavity.

[0015] The heating element has a columnar end and a flange at the other end; the columnar end of the heating element extends through the central hole of the plane wall into the aerosol generator insertion cavity, and the flange end of the heating element is tightly fitted with the inner circumference of the sealing cavity of the part.

[0016] A sealing element is located within the sealing cavity of the component and is interference-fitted between the flange end of the heating element and the bottom of the appliance housing.

[0017] Furthermore, the inner wall of the aerosol generator insertion cavity and the side of the planar wall near the aerosol generator insertion cavity are provided with several protrusions.

[0018] Furthermore, a surrounding wall is provided below the insertion hole of the device housing to define the position of the heating cavity and make it coaxial with the insertion hole.

[0019] Furthermore, a perimeter wall is provided around the magnet at the bottom of the device housing for fixing the magnet.

[0020] Secondly, a dedicated power supply is provided for use with the aforementioned cigarette heating devices without built-in power sources, comprising:

[0021] Power supply housing;

[0022] The battery is housed within the power supply housing;

[0023] The power supply main control board is disposed inside the power supply housing, and the battery is electrically connected to the power supply main control board;

[0024] A power supply interface extends out of the power supply housing surface and is electrically connected to the power supply main control board for electrical connection with the power supply interface of the heated cigarette appliance.

[0025] The charging interface is electrically connected to the power control board and is used to connect an external power source to charge the battery.

[0026] Furthermore, it also includes a power magnet disposed inside the power supply housing and located on top of the power supply housing.

[0027] Furthermore, the power supply interface is a flexible contact that extends a certain height beyond the upper surface of the power supply housing.

[0028] This invention proposes a cigarette heating device without a built-in power supply and its dedicated power supply, which has the following beneficial effects:

[0029] 1. Currently, the built-in battery is an essential component of heated cigarette devices. Due to the limitations of current battery technology, the battery needs to work in a normal working environment to achieve its maximum efficiency. In some special climatic environments, such as extremely cold or hot environments, its efficiency is limited, which will reduce the performance of the heating device or limit its use. The heated cigarette device of this invention adopts an external power supply, which improves or avoids the user experience of most heated cigarette devices.

[0030] 2. Traditional heated cigarette devices with built-in batteries have limited battery life. Once a battery cycle is completed, the user must charge and wait for a certain amount of energy to be replenished before use. This invention's heated cigarette device can be connected to external power sources for various scenarios, including household power, general portable power, or dedicated power, thus eliminating this limitation.

[0031] 3. The heated cigarette appliance of the present invention, when connected to a dedicated external power supply, can achieve the same portability as existing heating appliances; it can also be connected to a regular power supply, thus expanding its application scenarios.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0039] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and "center," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. When an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there may be an intermediate element present. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means at least two.

[0040] like Figures 1 to 3 As shown, an embodiment of the present invention provides a cigarette heating device without a built-in power supply, comprising:

[0041] The appliance housing has an insertion hole.

[0042] A heating cavity is located inside the appliance housing and is coaxially arranged with the insertion hole, and a heating element 4 is disposed therein;

[0043] The appliance main control board 5 is disposed inside the appliance housing, and the heating element 4 is electrically connected to the appliance main control board 5;

[0044] The input / output unit 6 is disposed on the appliance housing and connected to the appliance main control board 5, and is used to control the start and stop of the heated cigarette appliance;

[0045] At least one power interface for connecting to an external power source is provided on the appliance housing and is electrically connected to the appliance main control board 5.

[0046] In one or more embodiments, such as Figure 1 , Figure 2As shown, the appliance housing includes a first upper housing 1 and a first lower housing 2 interconnected by multiple fasteners. A cylindrical cavity 3 is concentrically inserted into an insertion hole at one end of the first upper housing 1. A surrounding wall 13 with an inner diameter equal to or slightly larger than the outer diameter of the cavity is provided below the insertion hole of the first upper housing 1, ensuring that the insertion hole of the first upper housing 1 and the cavity 3 are coaxial. The other end of the cavity 3 contacts the plane of the first lower housing 2. The distance between the planes of the first upper housing 1 and the first lower housing 2 is equal to the length of both ends of the cavity 3, thus coaxially fixing the cavity 3 to the insertion hole position of the first upper housing 1. A planar wall 12 with a central opening is provided at the middle of both ends of the cavity 3, biased towards the first lower housing 2, dividing the cavity 3 into two sections: an aerosol generator insertion chamber and a part sealing chamber. The section from the planar wall 12 with the central opening to the insertion hole is the aerosol generator insertion chamber; the other end is the part sealing chamber, for inserting a heating element 4, which is cylindrical at one end and flanged at the other. The cylindrical end of the heating element 4 extends through the central hole of the planar wall 12 into the aerosol generator insertion cavity. The flange end of the heating element 4 is tightly fitted with the inner circumference of the cavity 3, and the flange plane is in contact with the plane of the planar wall 12. The other end of the flange plane is positioned between the planar end and the planar end of the first lower housing 2, where a soft part seal 11 is located. The seal 11 is interference-fitted with the part sealing cavity. The circumference of the seal 11 is larger than the inner diameter of the cavity 3, and its length is greater than the distance from the planar end of the flange to the planar end of the first lower housing 2, thus achieving cavity sealing. When the aerosol generator 10 is inserted through the insertion hole of the first upper housing 1, the cylindrical part of the heating element 4 pierces into the aerosol generator 10 along its axis.

[0047] In one or more embodiments, such as Figure 1 , Figure 2 As shown, the electrode wire at the flange end of the heating element 4 extends from the side groove of the cavity 3 near the first lower housing 2 via the sealing member 11 to the main control board 5 of the appliance, thus achieving circuit connection. The main control board 5 is fixed by the groove formed by the ribs provided on the first upper housing 1, which holds the side of the main control board 5 in place, and by the main body length of the main control board 5 being equal to the distance between the first upper housing 1 and the first lower housing 2. A trigger switch is provided on one side of the main control board 5. Human-machine interaction is achieved by pressing the input / output part 6 (button) provided on the side of the first upper housing. On the side of the main control board 5 opposite to the trigger switch near the first lower housing 2, a power interface 7 (usually a USB power interface) is provided. On the opposite side, no less than two connectors 8 extend from the main control board 5. The connectors 8 are conductive metal pins, and the end face of the metal pins is exposed through a hole coaxial with the plane of the first lower housing 2, forming a pin-type power interface. The first lower housing 2 is provided with a magnet 9. In some embodiments, the first lower housing 2 is provided with a perimeter wall near the connector 8 and at a symmetrical position on the opposite side, where the magnet 9 is fixedly placed.

[0048] In one or more embodiments, the diameter of the inner wall of the aerosol generator insertion cavity is larger than the outer diameter of the aerosol generator 10. A uniform array of local protrusions is provided on the plane of the planar wall 12 and the inner wall of the aerosol generator insertion cavity. The diameter of the array of protrusions on the inner wall of the aerosol generator insertion cavity is slightly smaller than the diameter of the aerosol generator 10. When the aerosol generator 10 is inserted into the aerosol generator insertion cavity, the gap formed by every two adjacent protrusions on the inner wall of the aerosol generator insertion cavity and the plane of the planar wall 12 and the outer diameter of the aerosol generator 10 forms an "L" shaped space. When the power interface is connected to a power source, the user sends a signal to the main control board 5 of the appliance through the input / output unit 6, which provides a specific output to drive the heating element to generate energy, causing the aerosol generator to produce aerosol. When the user inhales at the exposed end of the aerosol, the airflow flows in from the insertion hole of the first upper housing 1, enters through multiple "L"-shaped spaces from the suction end of the aerosol generator 10, and then flows out from the exposed end of the aerosol generator 10, thus realizing the working process.

[0049] like Figure 3 As shown, the heated cigarette appliance provided in the above embodiments does not have a built-in power supply. When the heated cigarette appliance is working, it is connected to the power interface through the power input line 14. The other end of the power input line 14 is connected to a household power supply to realize power input and provide power to the appliance, ensuring that it can be used in indoor application scenarios. In some embodiments, the power interface of the heated cigarette appliance can be preferably configured as a standard USB power interface. When the user is in a non-indoor scenario, the heated cigarette appliance can be connected to a power bank or a dedicated power supply designed for this heated cigarette appliance to achieve operation. When using a power bank, a standard USB charging cable is used, with one end connected to the power interface of the heated cigarette appliance and the other end connected to the output interface of the power bank. Current input is realized when the power bank is in the current output state, driving the heated cigarette appliance to work.

[0050] This invention also provides a dedicated power supply for use with the heated cigarette appliance without a built-in power supply provided in the foregoing embodiments, such as... Figure 4 As shown, it includes:

[0051] Power supply housing;

[0052] Battery 17 is disposed inside the power supply housing;

[0053] The power control board 18 is disposed inside the power housing, and the battery 17 is electrically connected to the power control board;

[0054] The power supply interface 19 extends out of the surface of the power supply housing and is electrically connected to the power supply main control board 18 for electrical connection with the power supply interface of the heated cigarette appliance.

[0055] The charging interface 20 is electrically connected to the power control board 18 and is used to connect an external power source to charge the battery 17.

[0056] In one or more embodiments, such as Figure 4 , Figure 5 As shown, the power supply housing includes a second upper housing 15 and a second lower housing 16 interconnected by multiple fasteners. A battery 17 and a power control board 18 are disposed within the cavity of the power supply housing. A charging interface 20 is provided on the second lower housing 16, and the charging interface 20 is electrically connected to one end of the power control board 18. The function of the power control board 18 is to store the electrical energy received through the charging interface 20 using the battery 17, and after connecting to the heated cigarette appliance, to input the energy from the battery 17 to the heated cigarette appliance through the power supply interface 19, thereby enabling the heated cigarette appliance to operate. When the dedicated power supply is connected to the heated cigarette appliance, the connection method uses a non-standard USB interface or a USB-like interface, employing a non-wired connection. Specific implementations include nested male / female terminal connections, but in this embodiment, a suction contact connection is preferred. Specifically, the power supply interface is preferably a flexible contact extending a certain height from the plane of the second upper housing. The flexible contact is a conductive part that protrudes from the second upper housing, its protrusion height can be changed under force, and it possesses a certain resistance.

[0057] In some embodiments, the dedicated power supply can be assembled with the heated cigarette appliance by snapping the power supply housing into the appliance housing. In this embodiment, it is preferable to set the power magnet 21 in the second upper housing 15 corresponding to the position of the electromagnet inside the heated cigarette appliance. Specifically, the power magnet 21 is fixedly placed in the perimeter wall set on both sides of the plane of the second upper housing 15 inside the power supply housing. The dedicated power supply and the heated cigarette appliance can be easily connected and separated. When the heated cigarette appliance and the dedicated power supply are connected, the heated cigarette appliance and the dedicated power supply form a unified appearance and constitute a visual whole.

[0058] like Figure 5 As shown, when using a dedicated power supply, the power supply magnet and the magnet inside the heated cigarette device are attracted and fixed by the principle of attraction between opposite poles of magnets. When the heated cigarette device is fixed to the dedicated power supply, multiple flexible contacts on the dedicated power supply that protrude from the second upper shell are connected to multiple pin-type connectors of the heated cigarette device. This allows the output current of the dedicated power supply to form a current path through the flexible contacts and connectors, thus enabling the heated cigarette device to work.

[0059] It should be noted that the heating cigarette appliance provided in this embodiment of the invention has input power including direct input from household power, input from mobile power, and input from dedicated power. Different electrical parameters correspond to different voltages, frequencies, and currents. However, the final load and required power of the heating cigarette appliance are constant. Therefore, the main control board of the heating cigarette appliance has the electrical function of accepting multiple different voltage and current inputs and outputting them in the same way. "Same way" does not mean a specific current, voltage, or frequency, but rather that regardless of the output electrical method, within a unit time and within several sub-unit time regions formed by dividing that unit time, the main control board can output the energy required for the aerosol generator to volatilize aerosols. Automatic identification of power sources for different scenarios is achieved by, but is not limited to, detecting the power input voltage and current, as well as the sensor signals of the dedicated power source, through the main control board, and then rationally distributing the output current and voltage to achieve optimal output. The implementation circuit of the main control board is existing technology and will not be described further here.

[0060] The cigarette heating device without built-in power supply and its dedicated power supply provided in the above embodiments have the following advantages:

[0061] 1. Currently, the built-in battery is an essential component of heated cigarette devices. Due to the limitations of current battery technology, the battery needs to work in a normal working environment to achieve its maximum efficiency. In some special climatic environments, such as extremely cold or hot environments, its efficiency is limited, which will reduce the performance of the heating device or limit its use. The heated cigarette device of this invention adopts an external power supply, which improves or avoids the user experience of most heated cigarette devices.

[0062] 2. Traditional heated cigarette devices with built-in batteries have limited battery life. Once a battery cycle is completed, the user must charge and wait for a certain amount of energy to be replenished before use. This invention's heated cigarette device can be connected to external power sources for various scenarios, including household power, general portable power, or dedicated power, thus eliminating this limitation.

[0063] 3. The heated cigarette appliance of the present invention, when connected to a dedicated external power supply, can achieve the same portability as existing heating appliances; it can also be connected to a regular power supply, thus expanding its application scenarios.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
