[0002] To enhance user experience, some e-cigarette devices incorporate touch functionality, integrating a touchscreen into the device's casing. Users can interact with the touchscreen by swiping or touching it, displaying corresponding lighting effects and improving aesthetics and usability. However, current touchscreens on e-cigarette devices often suffer from unresponsiveness or delayed reactions, negatively impacting the consumer experience and product sales. Utility Model Content

[0003] The purpose of this invention is to provide an electronic atomizing device that solves the technical problem of unresponsive or delayed response of the touch screen in existing electronic atomizing devices when touched by the user.

[0004] This invention is achieved as follows: an electronic atomizing device, comprising an atomizing component and a touch control component;

[0005] An atomizing component includes a housing and an atomizing body. The housing has a mounting cavity, and the atomizing body is disposed in the mounting cavity and used to atomize an aerosol matrix.

[0006] The touch control assembly includes a touch control circuit board, a lamp board, and a cover plate stacked sequentially. The cover plate is connected to the atomizing body. The lamp board and the touch control circuit board are disposed in the mounting cavity. The lamp board has at least one first through hole. The touch control assembly also includes at least one contact protrusion disposed on the cover plate facing the touch control circuit board. Each contact protrusion passes through a first through hole and is electrically connected to the touch control circuit board. The touch control circuit board is electrically connected to the lamp board and is used to control the lamp board to emit light according to the signal changes transmitted by the cover plate.

[0007] In one embodiment, a conductive layer is provided between the lamp board and the touch circuit board. The conductive layer is electrically connected to the touch circuit board. The conductive layer has at least one second through hole, and the second through hole corresponds one-to-one with the first through hole.

[0008] In one embodiment, the touch circuit board has solder joints exposed at the first through hole, and the contact protrusion abuts against the solder joints.

[0009] In one embodiment, the touch component further includes a conductive structure disposed on the side of the contact protrusion facing the touch circuit board, the conductive structure being in electrical contact with the touch circuit board.

[0010] In one embodiment, the conductive structure includes a conductive coating applied to the surface of the contact protrusion, the conductive coating being in electrical contact with the touch circuit board.

[0011] In one embodiment, the contact protrusions are mesh-like.

[0012] In one embodiment, the contact protrusion is integrally formed with the cover plate.

[0013] In one embodiment, the contact protrusions are provided in multiple ways, and the number of the first through holes is equal to the number of the contact protrusions.

[0014] In one embodiment, the atomizing component further includes a middle shell connected to the outer shell and located within the mounting cavity, the outer shell having a mounting hole, the cover plate covering the mounting hole, and the touch circuit board mounted on the middle shell.

[0015] In one embodiment, the electronic atomizing device further includes a control component, which includes a main circuit board and a battery both disposed within the mounting cavity. The main circuit board is electrically connected to the battery, and the touch circuit board is electrically connected to the battery.

[0016] The technical advantage of this invention over existing technologies is as follows: When a user touches the cover plate with their finger, a capacitor is formed between the finger and the cover plate. The magnitude of this capacitor varies depending on factors such as the distance between the finger and the cover plate and the contact area. Since the cover plate is electrically connected to the touch circuit board via contact protrusions, it directly transmits the capacitance change signal to the touch circuit board. The touch circuit board converts this capacitance change signal into an electrical signal and transmits it to the touch chip on the board. The touch chip amplifies and filters this electrical signal, converting it into a digital signal and calculating the touch position, pressure, and other information based on a preset algorithm. The touch circuit board then generates corresponding control signals based on this touch information to control the LED display to show a flowing light effect. For example, the touch position may correspond to different lighting effect modes, and the touch pressure may correspond to parameters such as the speed or brightness of the lighting effect. In this way, the signal change that occurs when a finger touches the cover is directly transmitted from the cover to the touch circuit board, eliminating the detection step and improving the transmission speed of the capacitance change signal. When the user uses the touch function of the electronic atomizing device, the capacitance change signal can be transmitted to the touch circuit board in real time when the user makes a touch action, achieving instant touch feedback, sensitive touch control, and avoiding the problem of delayed response.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] This utility model embodiment provides an electronic atomizing device. Please refer to [link / reference]. Figure 1 The electronic atomizing device includes an atomizing component 10 and a touch component 20, with the touch component 20 mounted on the atomizing component 10.

[0032] In this regard, please combine Figure 2 The atomizing component 10 includes a housing 11 and an atomizing body 12. The housing 11 forms an installation cavity 101, and the atomizing body 12 is disposed in the installation cavity 101. The atomizing body 12 can store an aerosol matrix and is used to atomize the aerosol matrix.

[0033] Specifically, the atomizing body 12 includes a support 121, an atomizing core 122, and a liquid storage cotton 123. The support 121 forms a liquid storage chamber 102, a main air passage, an air inlet passage, and an air outlet passage. The air inlet passage and the air outlet passage are respectively connected to the two ends of the main air passage. The liquid storage chamber 102 is connected to the side wall of the main air passage. The atomizing core 122 is disposed in the main air passage and forms an atomizing air passage connected to the air inlet passage and the air outlet passage. The liquid storage cotton 123 is disposed in the liquid storage chamber 102 and is used to store the aerosol matrix. The liquid storage cotton 123 can absorb and retain the aerosol matrix. The atomizing core 122 is used to absorb the aerosol matrix in the liquid storage cotton 123 and atomize the aerosol matrix into an aerosol, which is then discharged into the atomizing air passage. When the user inhales, external air enters the atomizing air passage through the air inlet passage to draw the aerosol into the mouth through the air outlet passage.

[0034] Please combine Figure 3 The touch control component 20 includes a touch control circuit board 21, a lamp board 22, and a cover plate 23 stacked sequentially. The cover plate 23 is connected to the atomizing body 12, and the lamp board 22 and the touch control circuit board 21 are disposed within the mounting cavity 101. The touch control circuit board 21 is electrically connected to the lamp board 22 and is used to control the lamp board 22 to emit light. The cover plate 23 is located in the light-emitting direction of the lamp board 22 and is able to transmit light. The touch control circuit board 21, the lamp board 22, and the cover plate 23 can be connected as a single unit, or the touch control circuit board 21 can be fixedly connected to the lamp board 22, with the lamp board 22 and the cover plate 23 spaced apart or abutting each other; or the touch control circuit board 21 can abut against or be spaced apart from the lamp board 22, with the lamp board 22 and the cover plate 23 fixedly connected; or the touch control circuit board 21 can abut against or be spaced apart from the lamp board 22, with the lamp board 22 and the cover plate 23 abutting against or being spaced apart. There are no restrictions here, as long as the three components are stacked. The light board 22 can be an OLED (Organic Light-Emitting Diode) light board, an LED (Light Emitting Diode) light board, an LCD (Liquid Crystal Display) light board, a digital tube light board, or a light board with LED beads. The touch circuit board 21 can be a rigid printed circuit board or a flexible printed circuit board (FPC).

[0035] In this embodiment, the light board 22 is a digital tube light board, where a digital tube is a display device composed of multiple LEDs. The touch circuit board 21 is a flexible printed circuit board, which can control the on / off state of different segments through time-division multiplexing to achieve dynamic effects such as flowing water and gradation. It should be noted that a shielding layer is provided on the light board 22 between the digital tubes, which can be used to shield the circuitry on the light board 22.

[0036] Please see Figure 3 and Figure 4The lamp panel 22 has at least one first through hole 221. The touch assembly 20 also includes at least one contact protrusion 24 disposed on the side of the cover plate 23 facing the touch circuit board 21. Each contact protrusion 24 passes through a first through hole 221 and is electrically connected to the touch circuit board 21. The cross-sectional dimension of the first through hole 221 may be slightly larger than the cross-sectional dimension of the contact protrusion 24 to facilitate the insertion of the contact protrusion 24 and reduce the requirements for installation accuracy. The cross-sectional dimension of the first through hole 221 may also match the cross-sectional dimension of the contact protrusion 24 to improve the structural compactness of the touch assembly 20; no limitation is made here. The touch circuit board 21 is electrically connected to the lamp panel 22 and is used to control the lamp panel 22 to emit light according to the signal changes transmitted by the cover plate 23. The aforementioned signal changes include, but are not limited to, changes in capacitance signals and changes in pressure signals. In the following embodiments, changes in capacitance signals are used as an example for description.

[0037] When a user touches the cover plate 23 with their finger, a capacitor is formed between the finger and the cover plate 23. The size of this capacitor varies depending on factors such as the distance between the finger and the cover plate 23 and the contact area. Since the cover plate 23 is electrically connected to the touch circuit board 21 through the contact protrusion 24, the cover plate 23 directly transmits the capacitor change signal to the touch circuit board 21. The touch circuit board 21 converts the capacitor change signal into an electrical signal and transmits it to the touch chip on the touch circuit board 21. The touch chip amplifies and filters the electrical signal, converts it into a digital signal, and calculates the touch position, pressure, and other information according to a preset algorithm. Then, the touch circuit board 21 can generate corresponding control signals based on the touch information to control the light panel 22 to display a flowing light effect. For example, the touch position may correspond to different light effect modes, and the touch pressure may correspond to parameters such as the speed or brightness of the light effect. In this way, the signal change that occurs when a finger touches the cover plate 23 is directly transmitted from the cover plate 23 to the touch circuit board 21, eliminating the detection step and improving the transmission speed of the capacitance change signal. When the user uses the touch function of the electronic atomizing device, the capacitance change signal can be transmitted to the touch circuit board 21 in real time when the user makes a touch action, achieving instant touch feedback, sensitive touch control, and avoiding the problem of delayed response.

[0038] It should be noted that the touch circuit board 21 can also control the light panel 22 to display information such as time, power, and liquid volume in the liquid storage chamber 102.

[0039] Please see Figure 2In some embodiments, the electronic atomizing device further includes a control component 30, which is disposed within the mounting cavity 101 and includes a main circuit board 31 and a battery 32. Both the main circuit board 31 and the touch control circuit board 21 are electrically connected to the battery 32. The main circuit board 31 is electrically connected to the atomizing core 122. The battery 32 provides power to the atomizing core 122 and the touch control component 20. The main circuit board 31 controls the atomizing core 122 to atomize the aerosol matrix, and the touch control component 20 can be used to display lighting effects for a more user-friendly touch display.

[0040] Optionally, the control component 30 also includes a button 33, which is disposed on the housing 11 and is disposed opposite to the trigger switch 311 of the main circuit board 31. When the user presses the button 33, the button 33 can trigger the trigger switch 311 to send a trigger signal to the main circuit board 31. After receiving the trigger signal, the main circuit board 31 controls the atomizing core 122 to heat up.

[0041] Optionally, the control component 30 also includes a connector 34, which is mounted on the main circuit board 31 and electrically connected to the main circuit board 31. The housing 11 has a connector hole opposite to the connector 34. The connector 34 can be used to plug in an external power plug to charge the battery 32.

[0042] In other embodiments, the control component 30 may also be separately disposed from the atomizing component 10, and the control component 30 and the atomizing component 10 may be detachably connected.

[0043] Please see Figure 3 and Figure 5 In some embodiments, the atomizing component 10 further includes a middle shell 13 connected to the outer shell 11 and located in the mounting cavity 101. The outer shell 11 has a mounting hole 111, and a cover plate 23 covers the mounting hole 111. The touch circuit board 21 is mounted on the middle shell 13. In this way, the middle shell 13 can support the touch circuit board 21. During installation, the touch circuit board 21 can be installed on the middle shell 13 first, then the middle shell 13 and the outer shell 11 can be assembled, and finally the cover plate 23 can be fastened to the mounting hole 111 of the outer shell 11 to achieve rapid assembly of the touch component 20 and reduce the requirements for installation accuracy.

[0044] Please see Figure 4In some embodiments, a conductive layer 25 is provided between the lamp board 22 and the touch circuit board 21. The conductive layer 25 is electrically connected to the touch circuit board 21. The conductive layer 25 has at least one second through hole 251, and the number of second through holes 251 is equal to the number of first through holes 221. The second through holes 251 and the first through holes 221 correspond one-to-one. That is, the second through holes 251 and the first through holes 221 are connected in their axial direction to expose the electrical connection positions on the touch circuit board 21. The size of the first through hole 221 and the size of the second through hole 251 can be the same for uniform processing, or they can be different. There is no limitation here, as long as the contact protrusion 24 can make electrical contact with the touch circuit board 21.

[0045] The conductive layer 25 typically possesses good conductivity and high sensitivity to capacitance changes. When the cover plate 23 is touched, although it can directly transmit the capacitance change signal to the touch circuit board 21, this signal may be weak and unstable. The conductive layer 25 can more effectively sense the minute capacitance changes caused by touch and convert them into a more obvious and stable electrical signal before transmitting it to the touch circuit board 21, thus improving the accuracy and reliability of touch detection. The conductive layer 25 can also form a relatively uniform electric field beneath the cover plate 23. When a finger touches the cover plate 23, the change in the electric field becomes more regular and easier to detect. The conductive layer 25 may be made of materials including, but not limited to, indium tin oxide (ITO), graphene, and conductive polymers.

[0046] In some embodiments, the touch circuit board 21 has solder joints exposed at the first through hole 221, and the contact protrusion 24 abuts against the solder joints. The contact protrusion 24 can abut against the solder joints after being inserted into the first through hole 221, so as to achieve electrical contact between the contact protrusion 24 and the touch circuit board 21.

[0047] In other embodiments, an electrical connector may also be provided on the touch circuit board 21, and the contact protrusion 24 may be plugged into the electrical connector. In this case, the contact protrusion 24 may also serve as an electrical connector.

[0048] Please see Figure 4 In some embodiments, the touch assembly 20 further includes a conductive structure 26 disposed on the side of the contact protrusion 24 facing the touch circuit board 21, the conductive structure 26 being in electrical contact with the touch circuit board 21. The conductive structure 26 can improve the stability of the electrical contact between the contact protrusion 24 and the touch circuit board 21, and improve the conductivity of the contact protrusion 24.

[0049] Optionally, the conductive structure 26 includes a conductive coating applied to the surface of the contact protrusion 24, the conductive coating being in electrical contact with the touch circuit board 21. The conductive coating is made of conductive filler, including but not limited to metal conductive coatings (e.g., silver coatings, copper coatings, gold coatings, etc.), carbon-based conductive coatings (e.g., graphene coatings, carbon nanotube coatings, conductive carbon black coatings, etc.), and metal oxide conductive coatings (e.g., indium tin oxide coatings, zinc oxide coatings, tin oxide coatings, etc.).

[0050] Compared to other types of conductive structures 26, the conductive coating has excellent surface properties, adapting to different surface characteristics of the contact protrusions 24 and maintaining a tight fit with them. Furthermore, due to its thinness, the conductive coating has minimal impact on the overall weight and shape of the touch component 20. The conductive coating also boasts advantages such as simple processing and ease of integration. Common coating methods include spraying, brushing, dipping, and spin coating, which do not require complex equipment or high-precision processing techniques, facilitating rapid processing of the touch component 20. Moreover, the conductive coating's conductivity can be precisely controlled by adjusting parameters such as the type, content, particle size, and thickness of the conductive filler. In addition to conductivity, the conductive coating can also provide other functions such as corrosion resistance, wear resistance, insulation, and electromagnetic shielding.

[0051] Since the electrical contact between the cover plate 23 and the touch circuit board 21 may amplify electromagnetic interference, the conductive coating can be configured to provide electromagnetic shielding. The conductive filler in this coating may contain shielding metals, carbon-based materials, or conductive polymers. In this way, the conductive coating forms a localized electromagnetic shielding area at the point where the contact protrusion 24 contacts the touch circuit board 21, effectively shielding the electromagnetic waves generated by the touch circuit board 21 and reducing their radiation into the surrounding space. It also prevents external electromagnetic waves from interfering with the touch circuit board 21. Of course, methods to reduce electromagnetic interference are not limited to this; for example, the influence of electromagnetic interference can be reduced by adjusting the sensitivity of other controllers. This is not a limitation here.

[0052] In some embodiments, both the cover plate 23 and the contact protrusion 24 are made of plastic material, which has good structural strength and wear resistance to improve the service life of the touch component 20.

[0053] Optionally, the contact protrusion 24 and the cover plate 23 are integrally formed. That is, the contact protrusion 24 and the cover plate 23 can be injection molded together to improve the connection strength between them.

[0054] In other embodiments, the cover plate 23 may also be made of glass or composite material, and the contact protrusion 24 may be made of the same material as the cover plate 23 or different material. The two may be integrally formed or bonded together by conductive adhesive.

[0055] Please see Figure 3 and Figure 6 In some embodiments, the contact protrusions 24 are mesh-like. It is understood that the contact protrusions 24 have multiple through holes 241 along a direction perpendicular to the cover plate 23, forming a mesh-like structure. The cross-section of the through holes 241 can be square, circular, elliptical, or irregular, and the multiple through holes 241 can be arranged in an array for easy processing. The cover plate 23 and the contact protrusions 24 can be manufactured using processes such as mold forming and injection molding. Due to the regularity of the mesh structure, the mold manufacturing difficulty is relatively low. During injection molding, the molten plastic can uniformly fill the mold cavity, resulting in mesh-like protrusions with high dimensional accuracy and good surface quality. Therefore, forming the contact protrusions 24 into a mesh shape during manufacturing is relatively easy and allows for precise control of the shape and size of the contact protrusions 24, ensuring mesh consistency and uniformity, which is beneficial for large-scale production and reduces production costs. Furthermore, the mesh-like contact protrusions 24 also facilitate heat dissipation from the touch circuit board 21 and increase the contact area with the touch circuit board 21. When the contact protrusion 24 is made of plastic, the mesh-like contact protrusion 24 is more likely to undergo elastic deformation to adapt to the shape of the solder points or electrical connectors on the touch circuit board 21, thereby achieving stable electrical contact with the touch circuit board 21.

[0056] It should be noted that the conductive coating can be applied to the entire mesh-like surface of the contact protrusion 24 to increase the area of ​​the highly conductive region of the contact protrusion 24.

[0057] Please see Figure 3 and Figure 6 In some embodiments, multiple contact protrusions 24 are provided, and the multiple contact protrusions 24 are arranged at intervals. The number of first through holes 221 is equal to the number of contact protrusions 24. Correspondingly, when the contact assembly is provided with a conductive layer 25, the number of second through holes 251 is also equal to the number of contact protrusions 24. The arrangement of multiple contact protrusions 24 can improve the stability of contact with the touch circuit board 21. When the touch circuit board 21 is a flexible printed circuit board, the arrangement of multiple contact protrusions 24 can better adapt to the deformation of the flexible printed circuit board. The arrangement of multiple contact protrusions 24 can also improve the signal transmission quality, form contact redundancy, and avoid poor contact between the cover plate 23 and the touch circuit board 21 due to poor contact between individual contact protrusions 24 and the touch circuit board 21. In addition, when the change signal of the cover plate 23 is a pressure signal, the touch circuit board 21 can obtain the user's touch position by sensing the change of pressure signal transmitted by different contact protrusions 24.

[0058] In this embodiment, the number and position of the contact protrusions 24 can be adjusted and set according to the actual needs of display and sensing, and there is no limitation here.

[0059] exist Figure 4 In the illustrated embodiment, the touch circuit board 21, the conductive layer 25, and the lamp board 22 form an integrated structure and are installed in the mounting cavity 101. The cover plate 23 is snapped onto the housing 11 and is opposite to the lamp board 22. After the cover plate 23 is installed on the housing 11, the contact protrusion 24 can make electrical contact with the solder joints on the touch circuit board 21 through the first through hole 221 and the second through hole 251 and the conductive coating.

[0060] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
