Description

Technical Field

[0001] This invention relates to the field of atomization technology, and in particular to a battery rod and an electronic atomization device. Background Technology

[0002] To achieve single-point control, existing electronic atomizing devices typically use physical buttons, pressure sensors, or touch sensors. However, physical buttons are bulky and not conducive to miniaturization; pressure sensors are prone to misinterpretation by the detection chip due to variable external air pressure; and touch sensors require a separate touch panel, which is bulky, expensive, and increases assembly and design complexity. Summary of the Invention

[0003] This invention provides a battery rod and an electronic atomizing device to achieve single-point touch control of the battery rod, which eliminates the need for a separate touch panel, thereby achieving a small size and reducing costs.

[0004] To solve the above-mentioned technical problems, the first technical solution provided by the present invention is: a battery rod for electronic atomization, which can be used with an atomizer to achieve electronic atomization. The battery rod includes: a housing, on which a touch area is provided, the touch area being conductive; a touch sensing electrode located inside the housing and corresponding to the touch area, the touch area and the touch sensing electrode forming a sensing capacitor; and a control chip located inside the housing and connected to the touch sensing electrode, used to detect the capacitance value of the sensing capacitor and control the battery rod to perform corresponding operations based on the detected change in the capacitance value of the sensing capacitor.

[0005] The housing is made of metal, and the touch area is the portion of the outer surface of the housing corresponding to the touch sensing electrode.

[0006] The housing includes an insulating housing and a conductive layer disposed on the outer surface of the insulating housing corresponding to the touch area.

[0007] The housing includes an insulating housing and conductive layers disposed on the outer and inner surfaces of the insulating housing corresponding to the touch area; wherein the conductive layer on the inner surface of the insulating housing is the touch sensing electrode.

[0008] The touch sensing electrodes are spaced apart from the touch area.

[0009] The battery rod further includes a circuit board located inside the housing and insulated from the housing, wherein the touch sensing electrode and / or the control chip are integrated on the circuit board.

[0010] The touch sensing electrode is a metal pad.

[0011] The number of touch sensing electrodes is at least two.

[0012] When the touch area is touched, the capacitance value of the sensing capacitor changes.

[0013] To solve the above-mentioned technical problems, the second technical solution provided by the present invention is: an electronic atomizing device, comprising: an atomizer and a battery rod; wherein, the battery rod is used to supply power to the atomizer, and the battery rod is any of the battery rods described above.

[0014] The advantages of this invention, unlike existing technologies, lie in its inclusion of a housing with a touch area made of conductive material. A touch-sensing electrode, located within the housing and corresponding to the touch area, forms a sensing capacitor with the touch area. A control chip connected to the touch-sensing electrode detects the capacitance value of the sensing capacitor and generates a control command when a change in capacitance is detected, thereby controlling the battery rod to perform the corresponding operation. This achieves single-point touch control of the battery rod, eliminating the need for a separate touch panel, resulting in a smaller size and reduced cost. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0021] In this article, the term "and / or" simply describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "more" in this article means two or more objects.

[0022] The terms "first," "second," and "third" in this invention are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the stated features. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this invention are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the figures). If the specific posture changes, the directional indications also change accordingly. The terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] There are three existing single-point touch control solutions for electronic atomizing devices. The first is to use a physical button, which is controlled by a chip such as an MCU to collect high and low voltage signals and perform corresponding actions. The disadvantage of this method is that the physical button is too large, which is not conducive to miniaturization design, the cost is relatively high, and it is not conducive to integrated design. The second is to use a pressure sensor, which is controlled by a chip such as an MCU to collect changes in the pressure sensor output and then make a judgment. However, the external air pressure is not a stable value. Even a breeze can cause changes in air pressure, which can lead to misjudgment by the MCU and affect the vaping experience. The third is to use a touch sensor and a touch panel. The touch sensor collects signals from the touch panel and outputs the changes to the control chip such as an MCU, which then outputs corresponding control commands to perform the corresponding actions. However, this method requires a matching touch panel, which is costly and increases the design complexity. This invention provides a battery rod that can achieve single-point touch control without the need for a separate touch panel, thus achieving a smaller size and lower cost. The invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figure 1 This is a schematic diagram of the structure of a first embodiment of the battery rod of the present invention. The battery rod includes: a housing 11, on which a touch area 12 is disposed, wherein the touch area 12 is formed of a conductive material. The battery rod also includes a touch sensing electrode 13, located inside the housing 11 and corresponding to the touch area 12, wherein the touch area 12 and the touch sensing electrode 13 form a sensing capacitor. The battery rod also includes a control chip 14, located inside the housing 11 and connected to the touch sensing electrode 13, for detecting the capacitance value of the sensing capacitor, and generating a control command when a change in the capacitance value of the sensing capacitor is detected, so as to control the battery rod to perform corresponding operations.

[0026] Specifically, in this embodiment, the housing 11 is made entirely of a conductive material, such as a metal or other conductive plastic material. Preferably, the housing 11 is made of a metal. The material of the touch area 12 is the same as the material of the rest of the housing 11. The touch area 12 is the portion of the outer surface of the housing 11 corresponding to the touch sensing electrode 13.

[0027] In one specific embodiment, the projection of the touch area 12 and the touch sensing electrode 13 in the vertical direction completely coincides; or in another embodiment, the projection of the touch area 12 in the vertical direction is greater than the projection of the touch sensing electrode 13 in the vertical direction; or in another embodiment, the projection of the touch area 12 in the vertical direction is smaller than the projection of the touch sensing electrode 13 in the vertical direction, and the specifics are not limited.

[0028] Understandably, in order for the touch area 12 and the touch sensing electrode 13 to form a sensing capacitor, insulation is required between the touch area 12 and the touch sensing electrode 13; that is, the touch sensing electrode 13 and the touch area 12 can be spaced apart. In this embodiment, the touch area 12 and the touch sensing electrode 13 are separated by air and do not contact each other, thus achieving insulation through air. In another embodiment, an insulating layer can also be provided between the touch area 12 and the touch sensing electrode 13, with the insulating layer acting as a spacer to achieve insulation.

[0029] In one embodiment, the control sensing electrode 13 can be an independent conductive sheet, which is insulated inside the housing 11, as long as it can form a capacitance with the conductive housing 11.

[0030] Furthermore, the battery rod also includes a circuit board 15, which is located inside and insulated from the housing 11. The touch sensing electrodes 13 and / or the control chip 14 are integrated on the circuit board 15, specifically as follows: Figure 1 As shown. In this embodiment, the touch sensing electrode 13 is connected to the control chip 14 through the circuit structure on the circuit board 15, so that the control chip 14 can detect the capacitance value of the sensing capacitor. In one embodiment, the circuit board 15 can be a flexible circuit board, a printed circuit board, etc., and is not specifically limited. The control chip 14 is an MCU.

[0031] In one embodiment, the touch sensing electrode 13 can be a metal pad disposed on the circuit board 15. It can be a solid piece, such as circular, square, trapezoidal, or rhomboid, etc., and is not specifically limited. In another embodiment, the number of touch sensing electrodes 13 is at least two. For example, there can be multiple touch sensing electrodes 13, and each touch sensing electrode 13 is electrically connected to the others. For example, the touch sensing electrodes 13 are multiple electrically connected pads disposed on the circuit board. When disposed on the circuit board, compared with square pads, it can reduce the area occupied by the circuit board, and further reduce the area of ​​the circuit board.

[0032] like Figure 1 As shown, when the touch area 12 is touched, the capacitance value of the sensing capacitor changes. Specifically, when a user touches the touch area 12 while using the battery stick, a voltage is applied to the touch area 12. The control chip 14 detects the change in the capacitance value of the sensing capacitor and outputs a control command to control the battery stick to perform a corresponding operation. For example, if the battery stick is currently in sleep mode, and the user holds the touch area 12, the control chip 14 detects a capacitance change and outputs a control command to turn the battery stick on. Alternatively, if the battery stick is currently in the on mode, and the user holds the touch area 12, the control chip 14 detects a capacitance change and outputs a control command to turn the battery stick into sleep mode.

[0033] The battery rod provided by this invention has a touch area 12 on a housing 11 and a touch sensing electrode 13 inside the housing 11, forming a sensing capacitor between the touch area 12 and the touch sensing electrode 13. A control chip 14 detects changes in the sensing capacitor and outputs a control command when a change is detected to control the battery rod to perform a corresponding operation, thereby realizing a single-point touch design. It does not require a separate touch panel, has a smaller size, facilitates integrated design, eliminates assembly difficulties, reduces design costs, and is conducive to mass production.

[0034] Please see Figure 2 This is a schematic diagram of the second embodiment of the battery rod of the present invention. Similar to the above... Figure 1 Compared to the first embodiment shown, the difference lies in that the housing 11 shown in this embodiment includes an insulating housing 11 and a conductive layer 16 disposed on the outer surface of the insulating housing 11 corresponding to the touch area 12. Specifically, the conductive layer 16 is coated on a surface of the insulating housing 11 away from the circuit board 15. In one embodiment, the conductive layer 16 can be conductive ink or a metal film.

[0035] In this embodiment, the conductive layer 16 on the touch area 12 forms a sensing capacitor with the touch sensing electrode 13.

[0036] When the conductive layer 16 on the touch area 12 is touched, the capacitance value of the sensing capacitor changes. Specifically, when the user uses the battery stick and touches the conductive layer 16 on the touch area 12, a ground voltage is applied to the sensing area 12. The control chip 14 detects the change in the capacitance value of the sensing capacitor and outputs a control command to control the battery stick to perform corresponding operations. For example, if the battery stick is currently in sleep mode, when the user holds the touch area 12 of the battery stick, the control chip 14 detects a capacitance change and outputs a control command to control the battery stick to the on state. Alternatively, if the battery stick is currently in the on state, when the user holds the touch area 12 of the battery stick, the control chip 14 detects a capacitance change and outputs a control command to control the battery stick to the sleep state.

[0037] The battery rod provided by this invention has a touch area 12 on a housing 11 and a touch sensing electrode 13 inside the housing 11, forming a sensing capacitor between the touch area 12 and the touch sensing electrode 13. A control chip 14 detects changes in the sensing capacitor and outputs a control command when a change is detected to control the battery rod to perform a corresponding operation, thereby realizing a single-point touch design. It does not require a separate touch panel, has a smaller size, facilitates integrated design, eliminates assembly difficulties, reduces design costs, and is conducive to mass production.

[0038] Please see Figure 3This is a structural schematic diagram of the third embodiment of the battery rod of the present invention. Specifically, it is similar to the one described above. Figure 1 Compared to the first embodiment shown, the difference lies in that: in this embodiment, the housing 11 includes an insulating housing 11, a conductive layer 16 disposed on the outer surface of the insulating housing 11 corresponding to the touch area 12, and a conductive layer 17 disposed on the inner surface of the insulating housing 11 corresponding to the touch area 12. The conductive layer 17 on the inner surface of the insulating housing 11 is a touch sensing electrode 13.

[0039] In one embodiment, conductive layer 16 and conductive layer 17 may be conductive ink.

[0040] In this embodiment, conductive layer 16 and conductive layer 17 form a sensing capacitor. Control chip 14 is disposed on circuit board 15, and conductive layer 17 is connected to the circuit structure on circuit board 15 and further connected to control chip 14, thereby enabling control chip 14 to detect changes in sensing capacitor.

[0041] When the conductive layer 16 on the touch area 12 is touched, the capacitance value of the sensing capacitor changes. Specifically, when the user uses the battery stick and touches the conductive layer 16 on the touch area 12, a ground voltage is applied to the sensing area 12. The control chip 14 detects the change in the capacitance value of the sensing capacitor and outputs a control command to control the battery stick to perform corresponding operations. For example, if the battery stick is currently in sleep mode, when the user holds the touch area 12 of the battery stick, the control chip 14 detects a capacitance change and outputs a control command to control the battery stick to the on state. Alternatively, if the battery stick is currently in the on state, when the user holds the touch area 12 of the battery stick, the control chip 14 detects a capacitance change and outputs a control command to control the battery stick to the sleep state.

[0042] The battery rod provided by this invention has a touch area 12 on a housing 11 and a touch sensing electrode 13 inside the housing 11, forming a sensing capacitor between the touch area 12 and the touch sensing electrode 13. A control chip 14 detects changes in the sensing capacitor and outputs a control command when a change is detected to control the battery rod to perform a corresponding operation, thereby realizing a single-point touch design. It does not require a separate touch panel, has a smaller size, facilitates integrated design, eliminates assembly difficulties, reduces design costs, and is conducive to mass production.

[0043] Please see Figure 4 This is a schematic diagram of the structure of an embodiment of the electronic atomizing device of the present invention. The electronic atomizing device 40 includes an atomizer 41 and a battery rod 42; the battery rod 42 is used to supply power to the atomizer 41, wherein the battery rod 42 is the aforementioned Figures 1 to 3 The battery rod 42 as described in any embodiment.

[0044] The other structures of the battery rod 42 of the present invention are the same as those in the prior art, and will not be described in detail here.
