[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0024] The term "and / or" in this document simply describes a relationship between related objects, indicating that three possible relationships exist.

Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship. Furthermore, "many" in this document means two or more than two.

[0025] The terms "first", "second" and "third" in the present invention are only used for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" and "third" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined. All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications also change accordingly. The terms "including" and "having" in the embodiments of the present application and any variations thereof are intended to cover non-exclusive inclusions. 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 optionally also includes steps or units that are not listed, or optionally also includes other steps or components inherent to these processes, methods, products or devices.

[0026] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of such phrases in various places in the specification do not necessarily refer to the same embodiment, nor do they constitute independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] There are generally two ways of multi-touch in existing electronic atomization devices. One is that the touch chip senses the touch points of multiple channels and communicates with the MCU through the touch chip. This method requires two IO ports to communicate with the MCU, and multiple touch channels are required at the same time. The cost is relatively high, the circuit board design is also relatively complex, and interference between channels is easy. Another solution is that multiple touch channel signals are output in parallel to the MCU, which will occupy multiple IO resources, resulting in insufficient IO resources of the MCU, and the need to replace a larger packaging structure, which increases the circuit cost and also increases the area of the circuit board, making it difficult to achieve a small volume on the electronic atomization device. The present invention provides a battery rod and an electronic atomization device, which can realize a single-channel multi-touch solution, thereby reducing the area of the circuit board, reducing costs, and realizing a small volume structure. The following is a detailed description with reference to the accompanying drawings and specific embodiments.

[0028] See Figure 1 , is a schematic structural diagram of a first embodiment of a battery rod according to the present invention. Specifically, the battery rod includes: a shell 11, on which a touch area 12 is provided, and the touch area 12 is formed of an insulating material. Specifically, the shell 11 can be made of a conductive material, but the touch area 12 of the shell 11 is made of an insulating material. In one embodiment, the main body of the shell 11 can be formed of metal or conductive plastic, while the touch area 12 of the shell 11 is formed of an insulating plastic. It is understandable that the shell 11 can also be made of an insulating material as a whole, such as insulating plastic, and have a mark on the touch area 12 to identify the touch area 12. There is no specific limitation as long as the touch area 12 is made of an insulating material.

[0029] The battery rod further includes touch sensing electrodes 13, which are located within the housing 11 and corresponding to the touch area 12. Specifically, when different locations of the touch area 12 are touched, the touch sensing electrodes 13 generate different capacitance values. In one embodiment, the touch sensing electrodes 13 may be located on a circuit board 15. It is understood that the touch sensing electrodes 13 may also be independently located. A control chip 14 is located within the housing 11 and connected to the touch sensing electrodes 13. It is configured to detect the capacitance values at different locations on the touch sensing electrodes 13 and generate control instructions based on the detection results to control the battery rod to perform corresponding operations. The control chip 14 may be, for example, an MCU. Like the touch sensing electrodes 13, it may be integrated on the circuit board 15 and electrically connected to the touch sensing electrodes 13 via the circuit structure of the circuit board 15. In another embodiment, the touch sensing electrodes 13 are independently located, while the control chip 14 is integrated on the circuit board 15. The touch sensing electrodes 13 are connected to the control chip 14 via wires, enabling the control chip to detect the capacitance values on the touch sensing electrodes 13.

[0030] Specifically, the detection principle of the touch button is achieved by detecting the change in capacitance value. When the surrounding environment remains unchanged, the capacitance of the touch sensing electrode 13 is a very small fixed value. When the finger touches the touch area 12, the capacitance value of the touch sensing electrode 13 will change. Touch is achieved by detecting the capacitance value of the touch sensing electrode 13.

[0031] The capacitance between the flat plate capacitors is proportional to the contact area and inversely proportional to the contact distance. Specifically, the capacitance formula between the flat plate capacitors is: Wherein, K is the dielectric constant, S is the contact area (ie, the area of the finger projected on the touch sensing electrode 13 ), and D is the distance between the two plates of the capacitor.

[0032] In order to achieve multi-touch, in one embodiment of the invention, the area of the finger projected on the touch sensing electrode 13 is changed, thereby changing the capacitance value detected by the control chip 14. That is, the control chip 14 generates different control instructions according to the different capacitance values detected each time to control the battery rod to perform corresponding operations.

[0033] Specifically, in one embodiment, the touch sensing electrode 13 includes a plurality of touch sensing areas 131, wherein the plurality of touch sensing areas 131 may be interconnected or independent of each other. The area of each touch sensing area 131 is different. Specifically, the overlapping area of each touch sensing area 131 with the orthographic projection of the touch area 12 is different. In one embodiment, the overlapping area of the orthographic projection of the touch sensing area 12 gradually decreases in the extending direction of the touch area 12. Figure 2a and Figure 2b As shown, see Figure 2a , the touch sensing electrode 13 can be set to a triangle, which includes multiple touch sensing areas 131, and the areas of the multiple touch sensing areas 131 decrease successively. It can be understood that when the user's finger touches the sensing area 12, the projection area of the finger and each touch sensing area 131 on the touch sensing electrode 13 is different, so that when the finger touches different positions of the touch area 12, the control chip 14 detects different capacitance values, and outputs different control instructions according to different capacitance values to achieve single-channel multi-touch. It can be understood that when the finger touches the touch area 12, capacitance may be generated in multiple touch sensing areas 131 at the same time. The control chip 14 detects multiple capacitance values. At this time, the position corresponding to the touch sensing area 131 with the largest capacitance value can be selected as the position to be touched by the user, and the corresponding control instruction is output. In this embodiment, Figure 2a The touch sensing electrode 13 shown can be a slider sensor sheet, which can be independently provided or integrated on the circuit board 15. In another embodiment, the touch sensing electrode 13 can also be trapezoidal, which is not specifically limited.

[0034] In another embodiment, Figure 2b As shown, the touch sensing electrode 13 can also be configured as a metal pad, which is provided on the circuit board 15. Specifically, the touch sensing electrode 13 includes a plurality of circular pads, each pad being a touch sensing area 131. It is understandable that the area of each pad (touch sensing area 131) is different, thereby making the overlapping area of each pad and the orthographic projection of the touch area 12 different. Figure 2b As shown, the touch sensing area 131 decreases in area from left to right. Consequently, when a user's finger contacts the sensing area 12, the projected area of each touch sensing area 131 on the touch sensing electrode 13 is different. This allows the control chip 14 to detect different capacitance values when the finger contacts different locations on the touch area 12, thereby outputting different control instructions based on the different capacitance values, thereby achieving single-channel multi-touch. It will be appreciated that when a finger contacts the touch area 12, capacitance can be generated simultaneously in multiple touch sensing areas 131. In this case, the control chip 14 detects multiple capacitance values and selects the touch sensing area 131 with the largest capacitance value and outputs the corresponding control instruction.

[0035] In this embodiment, the touch sensing electrodes 13 are arranged parallel to the touch area 12. That is, the vertical distance between each touch sensing area 131 on the touch sensing electrode 13 and the corresponding touch area 12 is the same. Alternatively, in another embodiment, the vertical distance between each touch sensing area 131 on the touch sensing electrode 13 and the touch area 12 may be different. However, it is necessary to ensure that the capacitance value of the touch sensing area 131 on the touch sensing electrode 13 is different when a finger touches any position of the sensing area 12.

[0036] The battery rod described in this embodiment changes the overlap between the projection of a finger on the touch area 12 of the electronic atomizer and the touch sensing electrode 13, enabling the control chip 14 to detect capacitance values at different locations and output different control instructions. This achieves a single-channel multi-touch solution, reducing system costs and circuit board size.

[0037] See Figure 3 , is a schematic structural diagram of the second embodiment of the battery rod of the present invention. Figure 1 The difference from the first embodiment shown is that in this embodiment, the area of each touch sensing electrode on the touch sensing electrode 13 is the same. Specifically, the main control sensing electrode 13 in this embodiment can be rectangular, such as Figure 4As shown. In this way, the area of each touch sensing area 131 on the touch sensing electrode 13 is the same, so that when a finger contacts the touch area 12, the overlapping area of the projection of each touch sensing area 131 on the touch sensing electrode 13 remains unchanged. In order to enable the control chip 14 to detect different capacitance values when a finger contacts the touch area 12, further, in this embodiment, the touch sensing electrode 13 is tilted so that the vertical distance between each touch sensing area 131 on the touch sensing electrode 13 and the touch area 12 at the corresponding position is different. Specifically, as Figure 3 As shown, if the touch sensing electrodes 13 are disposed on the circuit board 15, the circuit board 15 is tilted, thereby tilting the touch sensing electrodes 13 as well. In another embodiment, if the touch sensing electrodes 13 are disposed independently, the circuit board 15 can be disposed parallel to the touch area 12, while only the touch sensing electrodes 13 are tilted. In this embodiment, the touch sensing electrodes 13 can be rectangular slider sensing sheets.

[0038] The battery rod described in this embodiment changes the distance between a finger and the touch sensing electrode 13 when it touches the touch area 12 of the electronic atomizer device, allowing the control chip 14 to detect the capacitance value at different locations and output different control instructions. This achieves a single-channel multi-touch solution, which can reduce system costs and the size of the circuit board 15.

[0039] See Figure 5 , is a schematic structural diagram of the third embodiment of the battery rod of the present invention. Figure 1 The difference from the first embodiment shown is that in this embodiment, the area of each touch sensing electrode on the touch sensing electrode 13 is the same. Specifically, the main control sensing electrode 13 in this embodiment can be a pad provided on the circuit board 15, such as Figure 6 As shown. In this way, the area of each touch sensing area 131 on the touch sensing electrode 13 is the same. Specifically, the overlapping area of each touch sensing area 131 and the orthographic projection of the touch area 12 is the same. Therefore, when a finger touches the touch area 12, the overlapping area with the projection of each touch sensing area 131 on the touch sensing electrode 13 remains unchanged. In order to enable the control chip 14 to detect different capacitance values when a finger touches the touch area 12, further, in this embodiment, the height of each pad (touch sensing area 131) is different, as shown. Figure 5 As shown, the vertical distance between each touch sensing area 131 on the touch sensing electrode 13 and the touch area 12 is different.

[0040] In this embodiment, if Figure 3 and Figure 5In the illustrated embodiment, the vertical distance between the touch sensing area 131 on the touch sensing electrode 13 and the touch area 12 increases sequentially. In another embodiment, the vertical distance between the touch sensing area 131 on the touch sensing electrode 13 and the touch area 12 may decrease sequentially, or the vertical distance between the touch sensing area 131 on the touch sensing electrode 13 and the touch area 12 may increase sequentially and then decrease sequentially, or the vertical distance between the touch sensing area 131 on the touch sensing electrode 13 and the touch area 12 may decrease sequentially and then increase sequentially. The specific configuration is not limited thereto, as long as the control chip 14 can detect different capacitance values when a finger contacts the touch area 12.

[0041] The battery rod described in this embodiment changes the distance between a finger and the touch sensing electrode 13 when it touches the touch area 12 of the electronic atomizer device, allowing the control chip 14 to detect the capacitance value at different locations and output different control instructions. This achieves a single-channel multi-touch solution, which can reduce system costs and circuit board size.

[0042] See Figure 7 , is a structural diagram of an embodiment of the electronic atomization device of the present invention, the electronic atomization device 40 includes an atomizer 41 and a battery rod 42; the battery rod 42 is used to power the atomizer 41, wherein the battery rod 42 is the above-mentioned Figures 1 to 6 The battery rod 42 according to any embodiment.

[0043] 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.

[0044] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
