Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an electronic atomization device and its heating curve switching device. Background Technology

[0002] Existing atomizing devices typically employ one or two heating curves during operation. When an atomizing device has two or more heating curves, a button is usually used to switch between them. Generally, the button operates in two ways: one is to design it separately from the start heating button, requiring an additional curve-switching button, which necessitates at least two buttons on the atomizing device; the other is to use a single button for both curve switching and heating, requiring a defined button operation, such as a series of presses to switch curves. Both of these methods either increase design complexity, making it difficult for users to distinguish the functions of each button, or increase operational complexity. Utility Model Content

Detailed Implementation

[0036] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0037] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0038] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0039] refer to Figure 1 This embodiment provides a heating curve switching device for an electronic atomizing device, including a detachably connected heating unit 10 and a control unit 20. The heating unit 10 contains a heating element 11, and a reflective mirror 12 is provided at the bottom of the heating unit 10 for connection to the control unit 20. The control unit 20 contains a control structure 23 and a signal transceiver. A direction recognition hole 21 is provided at the top of the control unit 20 for connection to the heating unit 10, and the signal transceiver and the direction recognition hole 21 are located on the same axis. The signal transceiver is electrically connected to the control structure 23. The heating unit 10 and the control unit 20 are connected in a forward orientation. When the direction identification hole 21 and the reflective mirror 12 are on the same axis, and the signal emitted by the transceiver passes through the direction identification hole 21 and reaches the reflective mirror 12, the reflective mirror 12 can reflect the signal to the control structure 23. The control structure 23 controls the heating element 11 to heat according to the first heating curve under the trigger of the signal. When the heating part 10 and the control part 20 are connected in opposite directions, the direction identification hole 21 and the reflective mirror 12 are located on two different axes, so that the control structure 23 cannot receive the signal. When the control structure 23 does not receive the signal, it controls the heating element 11 to heat according to the second heating curve.

[0040] In this embodiment, the heating curve switching device detachably connects the heating unit 10 and the control unit 20. Specifically, they can be detachably connected by a snap-fit ​​mechanism or by magnetic attraction. Furthermore, this detachable connection ensures normal heating operation of the atomizing device regardless of whether the heating unit 10 and the control unit 20 are connected in a forward or reverse orientation. It should be noted that the forward and reverse connections in this embodiment are relative. When the forward connection is the normal detachable connection, the reverse connection is achieved by rotating the heating unit 10 horizontally 180° relative to the control unit 20.

[0041] Furthermore, the bottom of the heating unit 10 is provided with multiple first spring pins 13, and the top of the control unit 20 is provided with multiple second spring pins 22. During operation, the first spring pins 13 and the second spring pins 22 come into contact, enabling electrical connection between the heating unit 10 and the control unit 20 via the spring pins. It should be noted that the first spring pins 13 and the second spring pins 22 are symmetrically arranged centered along the bottom of the heating unit 10 and the top of the control unit 20, respectively, to ensure that electrical connection between the heating unit 10 and the control unit 20 can be achieved even after the heating unit rotates horizontally by 180°.

[0042] In actual operation, the signal transceiver can be a signal light, and the signal emitted by the transceiver is a light signal (light beam). The user selects the connection method between the control unit 20 and the heating unit 10 as needed. When the user wants to use the first heating curve heating method, before starting heating, the heating unit 10 and the control unit 20 are connected in the forward direction, and then the heating is started, and the signal light is lit. At this time, the light emitted by the signal light reaches the reflecting mirror 12 through the direction recognition hole 21. The reflecting mirror 12 reflects the light back to the control structure 23 through the direction recognition hole 21. After receiving the light, the control structure 23 controls the heating element 11 to heat according to the first heating curve. When the user wants to use the second heating curve, before starting heating, the heating unit 10 is rotated 180° opposite to the control unit 20. Heating is then started. At this time, the indicator light and the reflector 12 are not on the same axis. Therefore, the light from the indicator light cannot be reflected by the reflector 12 through the direction recognition hole 21 to the control structure 23. Consequently, the control structure 23 controls the heating element 11 to heat using the second heating curve. By adopting the solution of this application, switching between different heating curves can be achieved simply by changing the assembly direction of the heating unit 10 and the control unit 20. This not only reduces the difficulty of design and operation but also makes it easier and faster for users to master the operation of the equipment.

[0043] This embodiment provides another heating curve switching device for an electronic atomizing device, including a detachably connected heating section 10 and a control section 20. The heating section 10 contains a heating element 11, and the control section 20 has a reflective mirror 12 at its top for connection to the heating section 10. The heating section 10 also contains a control structure 23 and a signal transceiver. The bottom of the heating section 10 for connection to the control section 20 has a direction recognition hole 21, and the signal transceiver and the direction recognition hole 21 are located on the same axis. The signal transceiver is electrically connected to the control structure 23. The heating section 10 and the control section 20 are connected in a forward orientation. When the direction identification hole 21 and the reflective mirror 12 are on the same axis, and the signal emitted by the transceiver passes through the direction identification hole 21 and reaches the reflective mirror 12, the reflective mirror 12 can reflect the signal to the control structure 23. The control structure 23 controls the heating element 11 to heat according to the first heating curve under the trigger of the signal. When the heating part 10 and the control part 20 are connected in opposite directions, the direction identification hole 21 and the reflective mirror 12 are located on two different axes, so that the control structure 23 cannot receive the signal. When the control structure 23 does not receive the signal, it controls the heating element 11 to heat according to the second heating curve.

[0044] Unlike the above scheme, in the heating curve switching device of this embodiment, a reflective mirror 12 is provided on the top surface of the control unit 20, a control structure 23 and a signal light are provided inside the heating unit 10, and a direction identification hole 21 is provided at the bottom of the heating unit 10 connected to the control unit 20. Similarly, the signal light and the direction identification hole 21 are located on the same axis. In use, when the heating unit 10 and the control unit 20 are connected in the forward direction, the direction identification hole 21 and the reflective mirror 12 are located on the same axis, and the light emitted by the signal light passes through the direction identification hole 21 and reaches the reflective mirror 12. The reflective mirror 12 can reflect the light to the control structure 23, and the control structure 23 controls the heating element 11 to heat according to the first heating curve under the trigger of the light. When the heating unit 10 and the control unit 20 are connected in the reverse direction, the direction identification hole 21 and the reflective mirror 12 are located on two different axes, so that the control structure 23 cannot receive the light. When the control structure 23 does not receive the light, it controls the heating element 11 to heat according to the second heating curve. This implementation scheme also allows switching between different heating curves simply by changing the assembly direction of the heating unit 10 and the control unit 20, which not only reduces the difficulty of design and operation, but also makes it easier and faster for users to master the use of the equipment.

[0045] In some embodiments, the control structure 23 includes a signal transmitting circuit 231 and a signal receiving circuit 232; the signal lamp is connected to the signal transmitting circuit 231, and the signal transmitting circuit 231 controls the signal lamp to light up after receiving a first signal; the signal receiving circuit 232 is used to output a second signal after sensing the light emitted by the signal lamp; the signal receiving circuit 232 is also used to output a third signal when the signal lamp is lit but no light emitted by the signal lamp is sensed.

[0046] Specifically, the control structure 23 also includes a control board, which can be a PLC control board or an MCU control chip. The indicator light can be a visible light LED or an infrared LED. In practical applications, regardless of whether the connection is forward or reverse, after heating is started, the signal transmitting circuit 231 receives the first signal, and the signal transmitting circuit 231 is turned on, illuminating the indicator light. At this time, when the heating unit 10 and the control unit 20 are forward connected, the signal receiving circuit 232 can sense the light emitted by the indicator light, and then the signal receiving circuit 232 outputs a second signal to the control board. After receiving the second signal, the control board controls the heating element 11 to heat according to the first heating curve. When the heating unit 10 and the control unit 20 are reverse connected, the signal receiving circuit 232 cannot sense the light emitted by the indicator light, and then the signal receiving circuit 232 outputs a third signal to the control board. After receiving the third signal, the control board controls the heating element 11 to heat according to the second heating curve.

[0047] Furthermore, refer to Figure 2 The signal transmitting circuit 231 includes a signal receiving terminal, a first resistor R1, a first MOSFET Q1, a second resistor R2, and a light-emitting diode G1. The signal receiving terminal P1 is used to receive a first signal. The first end of the first resistor R1 is connected to the positive power supply VCC1, and the second end of the first resistor R1 is connected to the signal receiving terminal P1. The source of the first MOSFET Q1 is connected to the positive power supply VCC1, the gate of the first MOSFET Q1 is connected to the signal receiving terminal P1, and the drain of the first MOSFET Q1 is connected to the first end of the second resistor R2. The second end of the second resistor R2 is connected to the positive terminal of the light-emitting diode G1, and the negative terminal of the light-emitting diode G1 is grounded.

[0048] Specifically, the working principle of the signal transmitting circuit 231 in this embodiment is as follows: after the signal receiving end P1 receives the first signal (low level signal), the first MOSFET Q1 is turned on, and the voltage of the positive terminal VCC1 of the power supply passes through the second resistor R2 and the light-emitting diode G1 (signal lamp) in sequence. At this time, the light-emitting diode G1 is lit up and emits light.

[0049] Furthermore, refer to Figure 2The signal receiving circuit 232 includes a transistor G2, a transistor Q3, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a second MOSFET Q2, and a signal output terminal P2. The first terminal of transistor G2 is connected to the positive power supply VCC1, and the second terminal of transistor G2 is connected to the first terminal of the third resistor R3, which is grounded. The base of transistor Q3 is connected to the second terminal of transistor G2, the collector of transistor Q3 is connected to the positive power supply VCC1, and the emitter of transistor Q3 is connected to the first terminal of the fourth resistor R4. The second terminal of the fourth resistor R4 is grounded; the first terminal of the fifth resistor R5 is connected to the positive terminal VCC1 of the power supply, and the second terminal of the fifth resistor R5 is connected to the drain of the second MOSFET Q2; the gate of the second MOSFET Q2 is connected to the emitter of the transistor Q3, and the source of the second MOSFET Q2 is grounded; the signal output terminal P2 is connected to the second terminal of the fifth resistor R5; when transistor G2 receives light, it generates a corresponding electrical signal, causing the signal output terminal P2 to output a second signal; when transistor G2 does not receive light, the signal output terminal P2 outputs a third signal.

[0050] Specifically, the working principle of the signal receiving circuit 232 in this embodiment is as follows: When the reflector 12 and the direction recognition hole 21 are on the same axis, that is, the heating part 10 and the control part 20 are connected in the same direction, the transistor G2 turns on after receiving light. At this time, the base of the transistor Q3 forms a high level, making the transistor Q3 turn on. Then, the gate of the second MOSFET Q2 also forms a high level, making the second MOSFET Q2 turn on. At this time, the level of the signal output terminal P2 is pulled low, forming a falling edge, so a low-level signal (i.e., the second signal) will be output. When the reflector 12 and the direction recognition hole 21 are not on the same axis, that is, the heating part 10 and the control part 20 are reversed, the transistor G2 cannot receive light, so it cannot turn on. Then, the transistor Q3 and the second MOSFET Q2 also cannot turn on. The voltage of the positive terminal VCC1 of the power supply will be output from the signal output terminal P2 through the fourth resistor R4. At this time, the level of the signal output terminal P2 is high, so the signal output terminal P2 will output a high-level signal (i.e., the third signal).

[0051] The second and third signals are both output to the control board, which controls the heating element 11 to heat according to different heating curves based on the different signals.

[0052] In one embodiment, the heating part 10 and the control part 20 have the same shape, and both the heating part 10 and the control part 20 have a symmetrical structure.

[0053] In practical applications, refer to Figure 1The heating part 10 and the control part 20 are designed to have the same shape, and both the heating part 10 and the control part 20 are symmetrical structures. This design allows the heating part 10 and the control part 20 to have a symmetrical appearance structure, which ensures that the appearance is not affected when the assembly direction of the heating part 10 is changed.

[0054] refer to Figure 3 The electronic atomization device provided in this embodiment includes the heating curve switching device as described above, as well as a power supply module 30 and a charging management module 40; wherein, the power supply module 30 is used to provide electrical energy to the heating curve switching device; the charging management module 40 is used to determine whether the power supply module 30 enters the discharge heating state or the charging replenishment state.

[0055] In practical applications, electronic atomizing devices are also equipped with a power supply module 30 and a charging management module 40. Generally, the power supply module 30 is located within the control unit 20, supplying power to the control structure 23 to ensure that heating operations corresponding to different heating curves can proceed normally during use. Furthermore, the charging management module 40 is used to determine the device's status, monitoring whether the device is in a discharge heating state or a charging replenishment state, to ensure that the device can perform normal discharge heating and charging replenishment operations.

[0056] Furthermore, refer to Figure 3 The electronic atomizing device also includes a display button 50, which is electrically connected to the control structure 23. The display button 50 is used to send a first signal to the signal sending circuit 231 through the control structure 23 after being triggered.

[0057] In practical applications, the electronic atomizing device also includes a display button 50. Specifically, the display button 50 can be set on the outer surface of the control unit 20. The display button 50 is electrically connected to the control board. The user can press the display button 50 to trigger the control board to send a first signal to the signal sending circuit 231, thereby starting the electronic atomizing device.
