[0002] With the rapid development of electronic technology, especially touch sensing technology, capacitive touch sensing technology has been widely used in a variety of home appliances and electronic devices due to its advantages such as long service life, flexible design, relatively low cost, and conducive to industrial design. For example, some existing electronic atomization devices are equipped with capacitive touch buttons so that users can control the on and off of the circuit in the electronic atomization device and the size of the circuit power by touch.

[0003] There are two main structures of existing capacitive touch buttons. One is that the circuit board relies on a conductive spring to conduct the current to the shell, and the other relies on the conductive metal connected to the conductive cloth to conduct the current to the shell. Both structures can provide the key flexibility and convenience required for touch buttons. However, the above two structures occupy a large space, and the product appearance is limited. They cannot achieve high sensitivity and fast response for small electronic products or electronic products with various appearances. In addition, in the above two structures, the shape accuracy of the touch piece for the user to touch is high, resulting in the shape of the touch piece can generally only be a plane or a regular arc surface, which cannot be applied to electronic products with small appearance structures or various appearances. Utility Model Content

[0016] According to another aspect of the present application, an electronic atomization device is provided, comprising an atomizer and a power supply assembly as described in the above scheme, wherein the power supply assembly is detachably connected to one side of the atomizer and electrically connected to the atomizer.

The pressing is sensitive and reliable, which solves the problem of low button sensitivity. In addition, since the manufacturing cost of the touch button structure is reduced, the production cost of the power supply assembly and the electronic atomization device is also effectively reduced.

[0036] The specific structures of the electronic atomization device, power supply assembly and touch button structure in the present application are described below. It is understandable that in other embodiments, the power supply assembly of the present application is not limited to being used only for powering or charging the electronic atomization device, but can also be used to power or charge any other small electronic products, and the touch button structure of the present application is not limited to being installed in the power supply assembly of the electronic atomization device, but can also be used to be installed in any electronic product or electronic device, which is not limited here.

[0037] See also Figure 1 and Figure 2 , Figure 1 The structure diagram of the electronic atomization device 10 in one embodiment of the present application is shown. Figure 2 An exploded schematic diagram of the electronic atomization device 10 is shown. The electronic atomization device 10 provided in one embodiment of the present application includes an atomizer 100 and a power supply assembly 200, wherein the power supply assembly 200 is detachably connected to one side of the atomizer 100 and electrically connected to the atomizer 100, and an atomizer medium is contained in the atomizer 100. When the atomizer 100 is not connected to the power supply assembly 200, the atomizer 100 can work alone, so as to heat and atomize the atomization medium contained therein to generate an aerosol for the user to inhale. When the atomizer 100 is connected to the power supply assembly 200, the power supply assembly 200 can charge the atomizer 100, so that the atomizer 100 can continue to work when its own power is exhausted.

[0038] Specifically, see Figure 3 In one embodiment, the atomizer 100 includes a second housing 110, an atomizer assembly 120 and a power supply assembly 130. The atomizer assembly 120 and the power supply assembly 130 are both arranged in the second housing 110. The power supply assembly 130 is electrically connected to the atomizer assembly 120. The power supply assembly 200 is detachably connected to the second housing 110 and electrically connected to the power supply assembly 130. One end of the second housing 110 has a suction nozzle 101, and the suction nozzle 101 is provided with an air outlet 101a. The atomizing medium is contained in the atomizing assembly 120. The power supply assembly 130 is used to supply power to the atomizing assembly 120 so that the atomizing assembly 120 can heat and atomize the atomizing medium, so that when the user uses the suction nozzle 101 to inhale, the aerosol generated by atomization can be inhaled into the user's mouth through the air outlet 101a. When the power supply component 130 is exhausted, since the power supply component 130 is electrically connected to the power supply component 200, the power supply component 200 can provide the electric energy stored inside itself to the power supply component 130; and when the power inside the power supply component 200 is exhausted, the power supply component 200 can be removed separately and connected to an external power source for charging.

[0039] For more details, please refer to Figure 3The atomizer assembly 120 includes an oil tank 121, a vent pipe 122 and an atomizer core 123. The vent pipe 122 is penetrated in the oil tank 121 so that the outer wall of the vent pipe 122 and the inner wall of the oil tank 121 form an oil storage chamber 120a for storing atomizing medium. The atomizer core 123 is arranged in the vent pipe 122 and is electrically connected to the power supply assembly 130. The vent pipe 122 is provided with an oil hole (not marked in the figure) connected to the oil storage chamber 120a. When the power supply assembly 130 supplies power, the atomizer core 123 can heat and atomize the atomizing medium that flows from the oil storage chamber 120a through the oil hole into the atomizer core 123, so that the generated aerosol can be discharged from the inside of the vent pipe 122 and the air outlet hole in turn.

[0040] In terms of the structure of the power supply assembly 130, the power supply assembly 130 includes a bracket 131, a second battery cell 132 and a second circuit board 133. The bracket 131 is connected to the bottom of the atomizer assembly 120. Specifically, the bracket 131 is connected to the bottom of the oil tank 121. The second battery cell 132 is arranged in the bracket 131 and is electrically connected to the second circuit board 133. The second circuit board 133 is electrically connected to the power supply assembly 200. The function of the bracket 131 is to fix the second battery cell 132 and the second circuit board 133 to prevent them from shaking at will and causing circuit abnormalities. The second battery cell 132 is used to store electricity, and the second circuit board 133 is used to control the on and off of the circuit in the atomizer 100 and control the charging and discharging of the second battery cell 132.

[0041] Combination Figures 1 to 4 In one embodiment, the power supply assembly 200 includes a first housing 210, a first battery cell 220 and a touch button structure 230. The first housing 210 is detachably connected to the second housing 110 of the atomizer 100, for example, by snap-on or magnetic connection. Figure 5 As shown, the touch button structure 230 includes a touch member 231 made of plastic material, the first shell 210 is provided with a mounting hole 211, the touch member 231 is at least partially embedded in the mounting hole 211, the rest of the touch button structure 230 and the first battery cell 220 are arranged in the first shell 210, the first battery cell 220 is electrically connected to the touch button structure 230, which is used to store electricity so that the power supply component 200 can be charged when the power supply component 200 is exhausted, and the touch button structure 230 is used for the user to touch. The user touches the touch member 231 so that the program can be used as a switch to control the on and off of the overall circuit of the electronic atomization device 10, and it can also be used as a functional switch for adjusting power to adjust the output size of the current to achieve the adjustment of the output power size, and the power supply component 200 can also be controlled by touching the touch member 231 to charge or stop charging the second battery cell 132 of the power supply component 130.

[0042] It can be seen that the touch button structure 230, as a key component, can be touched by the user's fingers, so that an inductive circuit can be formed and an induced current can be generated through the touch button structure 230. Therefore, when the user touches the touch member 231 to perform circuit switching and charging control, whether the touch button structure 230 can achieve high sensitivity and fast response becomes a key factor in determining the quality of the touch button structure 230; and as described in the background technology, how to make the touch member 231 of the touch button structure 230 compatible with electronic products with small or diverse appearances so that it can be applied to the above-mentioned electronic products is also a problem that needs to be solved urgently.

[0043] Therefore, to solve the above mentioned problems, please continue to refer to Figure 5 In one embodiment provided in the present application, the touch key structure 230 includes, in addition to the touch member 231, a conductive sheet 232, a spring needle assembly 233 and a first circuit board 234, wherein the conductive sheet 232 is attached to one side of the touch member 231, specifically to the side of the touch member 231 facing the first housing 210, the spring needle assembly 233 has a fixed end 233b and an abutting end 233a, the fixed end 233b is connected to the first circuit board 234, the abutting end 233a abuts against the side of the conductive sheet 232 away from the touch member 231, and the first circuit board 234 is electrically connected to the second circuit board 133 of the power supply assembly 130. When the side of the touch member 231 away from the conductive sheet 232 is touched by a finger, the touch member 231, the conductive sheet 232, the spring needle assembly 233, the first circuit board 234 and the second circuit board 133 can form a conductive sensing circuit. And under the abutting action of the conductive sheet 232, the abutting end 233a can shrink relative to the fixed end 233b and generate an elastic force that causes the abutting end 233a to extend and reset relative to the fixed end 233b, thereby ensuring that the abutting end 233a of the elastic pin assembly 233 can tightly abut against the conductive sheet 232, thereby ensuring the sensitivity and reliability of the user's touch control.

[0044] In a preferred embodiment, the conductive sheet 232 is made of a soft conductive material, such as conductive metal wool, so that when the abutting end 233a of the spring needle assembly 233 abuts against the conductive sheet 232, the contour of the conductive sheet 232 can be deformed into a contour shape that matches the surface of the inner side (i.e., the side facing the inside of the first shell 210) of the touch member 231 and fits the touch member 231. Further, in order to enhance the fitting effect, the inner side of the touch member 231 is coated with adhesive (such as double-sided adhesive, 3M adhesive or glue, etc.), and the touch member 231 and the conductive sheet 232 are bonded to each other through the adhesive, thereby preventing the conductive sheet 232 from falling off the touch member 231.

[0045] In this way, no matter what the external structure of the electronic atomization device 10 is, when the abutting end 233a of the spring needle assembly 233 abuts against the conductive sheet 232, it can produce interference contact with the conductive sheet 232, so that the conductive sheet 232 can be deformed and fit tightly to one side of the touch member 231, thereby improving the sensitivity and reliability of the touch button structure 230, and solving the problem of low button sensitivity when the inner surface of the product is an arc or irregular shape.

[0046] Furthermore, in order to enhance the conductive effect of the conductive sheet 232, a plurality of metal wires are arranged on the conductive sheet 232, such as copper wires, or metal wires of other materials, which are not limited to this. In this way, under the dual conductive effect of the conductive sheet 232 material itself and the metal wires, the conductive sensitivity of the touch key structure 230 can be increased.

[0047] In terms of the structure of the spring pin structure, the spring pin assembly 233 can be as follows: Figure 5 The standard component structure shown in the figure includes a fixing seat 2331 and a needle body 2332. The fixing seat 2331 is fixedly mounted on the first circuit board 234 by welding or screw connection, and the needle body 2332 is movably connected to the fixing seat 2331 by an elastic member (such as a spring, etc.). The fixing seat 2331 forms a fixed end 233b, and the end of the needle body 2332 away from the fixing seat 2331 forms an abutment end 233a. The elastic member is used to provide an elastic force to make the abutment end 233a extend and reset relative to the fixed end 233b.

[0048] It is understandable that the structure of the elastic needle assembly 233 is not limited to the structure described in the above embodiment, and the material of the needle body 2332 can also be made of an elastic and deformable material, so that it can also produce retractable elastic deformation relative to the fixing seat 2331, and there is no special limitation here.

[0049] In a preferred embodiment, the needle body 2332 and the first circuit board 234 are parallel to each other. By setting the needle body 2332 and the first circuit board 234 to be parallel to each other, the touch button structure 230 does not take up space and can be suitable for electronic atomization devices 10 products with a small space and a small outer tube. Of course, the needle body 2332 and the first circuit board 234 can also be set to be perpendicular to each other, or set at an angle, so that the touch button structure 230 is suitable for electronic atomization devices 10 products of various shapes.

[0050] When assembling the touch key structure 230, firstly, the spring needle assembly 233 and the first circuit board 234 are welded together to form a solution board assembly, and then the solution board assembly is fixed to the first housing 210 with screws. Then, the conductive sheet 232 is attached to the inner side of the touch member 231 by using adhesive, so that the conductive sheet 232 and the touch member 231 are integrated, and then the touch member 231 attached with the conductive sheet 232 is embedded in the mounting hole 211 of the first housing 210. Finally, the needle head of the spring needle assembly 233 is abutted against the conductive sheet 232, so that the needle head and the conductive sheet 232 are in interference contact to form a conductive loop. When a finger touches the touch member 231, an induction circuit can be formed to control the on and off of the circuit.

[0051] It should be noted that the touch button structure 230 can also be directly disposed on the atomizer 100, which is not limited here. The user touches the touch member 231 with a finger to control the operation of the atomizer 100.

[0052] In summary, the electronic atomization device 10 provided in the present application, by setting a power supply component 130 in the atomizer 100, and then setting a power supply component 200 that is detachably connected to the atomizer 100 and electrically connected to the power supply component 130, allows the atomizer 100 to work independently. When the power inside the power supply component 130 of the atomizer 100 is exhausted, the power supply component 200 can provide the electric energy stored inside itself to the power supply component 130, and can also be removed separately and charged with an external power supply, which is convenient for users to use and improves the user experience. Furthermore, by setting the touch button structure 230 of the above structure on the power supply component 130, on the one hand, the conductive performance is better than that of the traditional spring structure, and the reliability is high, and a touch button function with higher sensitivity can be achieved; on the other hand, the spring needle component 233 can be a standard part, the cost is lower than the spring, and the assembly method is simple; on the other hand, the conductive sheet 232 can be fitted to the inner surface of the touch key according to the contour shape of the inner surface of the touch key, so that the touch button structure 230 can match electronic products with different inner surface shapes, solving the problem of low sensitivity of the button when the inner surface of the product is curved or irregular.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
