DETAILED DESCRIPTION

[0026] The present application is described in detail below with reference to the accompanying drawings and optional embodiments. In the description of the present application, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating relative importance or implicitly indicating the number of indicated technical features. Therefore, unless otherwise specified, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

They are only for the convenience of describing the simplified description of the present application, and do not indicate that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0028] It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0029] like Figure 1 As shown, an embodiment of the present application discloses an electronic atomization device, wherein the electronic atomization device 10 includes an atomizer 100 and a power supply 200, wherein the atomizer 100 is used to heat the e-liquid or the cigarette to generate high-temperature steam, and the power supply 200 is used to provide power to the atomizer 100 and control the startup of the atomizer 100.

[0030] Specifically, Figure 2 and Figure 3As shown, the power supply 200 includes a bracket 210, a circuit board 220, a ejector pin 230 and an elastic member 240. The bracket 210 is fixedly connected to the circuit board 220. A mounting position 211 is provided on the bracket 210. The ejector pin 230 is fixed in the mounting position 211. One end of the ejector pin 230 is electrically connected to the heating element 110 in the atomizer 100. The other end of the ejector pin 230 is electrically connected to the circuit board 220 through the elastic member 240 to control the heating element 110 in the atomizer 100. It can be understood that the other end of the ejector pin 230 is not in direct contact with the circuit board 220. The other end of the ejector pin 230 is in contact with the elastic member 240, and the elastic member 240 is in contact with the circuit board 220, so that the current is transmitted among the ejector pin 230, the elastic member 240 and the circuit board 220.

[0031] Compared with the connection method of directly welding the ejector pin 230 and the circuit board 220, the embodiment of the present application adds an elastic member 240, and the ejector pin 230 is electrically connected to the circuit board 220 through the elastic member 240. The ejector pin 230 and the circuit board 220 do not need to be in direct contact, thereby avoiding the problem of disconnection caused by false welding when the ejector pin 230 and the circuit board 220 are welded; moreover, the embodiment of the present application uses the elastic member 240 as an electrical conduction structure. Under the action of elasticity, the elastic member 240 can always maintain tension, can have a good contact effect with the ejector pin 230 and the circuit board 220, realize stable electrical conduction, and can also buffer the ejector pin 230 during the installation process to prevent the ejector pin 230 from abnormal.

[0032] like Figure 3 and Figure 4 As shown, in the embodiment of the present application, the power supply 200 includes two ejector pins 230 and two elastic members 240. The two ejector pins 230 are electrically connected to the two ends of the heating element 110 respectively to realize the flow of current; the two elastic members 240 are respectively connected to the two ejector pins 230, so that the two ejector pins 230 are electrically connected to the circuit board 220 through the elastic members 240. At the same time, the bracket 210 is provided with two mounting positions 211, and the two ejector pins 230 are respectively fixed in the two mounting positions 211. Of course, the number of ejector pins 230 can also be adjusted as needed to realize the connection of one or more ejector pins 230 with the heating element 110 and the circuit board 220.

[0033] The power supply 200 also includes a microphone 250 and a microphone silicone 260. The microphone 250 is arranged on the side of the circuit board 220 facing the bracket 210 and is connected to the circuit on the circuit board 220 for sensing airflow. When sensing external airflow, the microphone 250 controls the heating element 110 to heat, so that the electronic atomization device 10 is in use. Correspondingly, an airway 212 is provided in the bracket 210, and one end of the airway 212 faces the microphone 250.

[0034] Moreover, the microphone silicone 260 is sleeved on the microphone 250 and leaks out of the side of the microphone 250 facing the bracket 210, so that the microphone silicone 260 protects the microphone 250 without affecting the normal use of the microphone 250, and can also prevent smoke oil and condensation from dripping onto the microphone 250 and affecting the normal use of the microphone 250.

[0035] The microphone 250 and the microphone silicone 260 are arranged at the edge of the circuit board 220, and the parts of the bracket 210 corresponding to the microphone 250 and the microphone silicone 260 are avoided to form a gap, forming a fool-proof design and facilitating the assembly of the product.

[0036] like Figure 5 As shown, the power supply 200 further includes a power supply 270 and a housing 280, wherein the bracket 210, the circuit board 220, the ejector pin 230, the elastic member 240 and the power supply 270 are all disposed in the housing 280, and the power supply 270 is disposed on a side of the circuit board 220 away from the bracket 210 and is electrically connected to the circuit board 220. The power supply 270 may be a dry cell or a storage battery, which is not limited here.

[0037] It should be noted that the atomizer 100 also has a shell 280 structure, and the entire shell of the electronic atomization device 10 is a split structure, which is composed of the shell in the atomizer 100 and the shell in the power supply 200. The shell in the atomizer 100 and the shell in the power supply 200 are connected by snaps, welding, etc. to achieve product assembly. Of course, the entire shell of the electronic atomization device 10 can also be an integrated structure, that is, the internal components in the atomizer 100 and the internal components in the power supply 200 are installed in one shell.

[0038] Combination Figure 3 , Figure 6 and Figure 8As shown, in the embodiment of the present application, two clamping columns 213 are provided on the bracket 210, and the clamping columns 213 are arranged on the side of the bracket 210 facing the circuit board 220. Two bayonet holes 223 are provided on the circuit board, and the ends of the two clamping columns 213 are connected to the two bayonet holes 223 one by one through buckles; at the same time, the column part of the clamping column 213 supports the circuit board 220 and the bracket 210, while ensuring the stability between the circuit board 220 and the bracket 210, it also avoids the distance between the circuit board 220 and the bracket 210 being too small during the assembly process, which affects the normal use of the elastic member 240 and the microphone 250.

[0039] At the same time, the two clamping columns 213 are arranged opposite to each other on the bracket 210, and the two mounting positions 211 are arranged opposite to each other on the bracket 210. It can be understood that the two clamping columns 213 are arranged on two opposite sides of the bracket 210, and the two mounting positions 211 are arranged on the other two opposite sides of the bracket 210. After the product is assembled, the structure on the bracket 210 corresponds to the structure on the circuit board 220 one by one, which further improves the stability of the internal structure of the product.

[0040] Combination Figure 4 , Figure 6 and Figure 7 As shown, as a specific embodiment, the ejector pin 230 is an integrated conductive structure, specifically including three parts: a contact portion 231, a fixing portion 232 and an extension portion 233, wherein the fixing portion 232 is located between the contact portion 231 and the extension portion 233, and two ends are respectively connected to the contact portion 231 and the extension portion 233; the fixing portion 232 is located in the mounting position 211, the contact portion 231 is located at one end of the fixing portion 232 facing the atomizer 100, protrudes from the top of the mounting position 211, and is electrically connected to the heating element 110; the extension portion 233 is located at one end of the fixing portion 232 away from the atomizer 100, protrudes from the bottom of the mounting position 211, and the cross-sectional area of ​​the fixing portion 232 is greater than the cross-sectional area of ​​the extension portion 233.

[0041] The elastic member 240 is specifically a spring, which is sleeved on the extending portion 233 , and one end of the spring abuts against the fixing portion 232 , and the other end of the spring abuts against the conductive area on the circuit board 220 .

[0042] Through the above-mentioned design of the ejector pin 230 and the elastic member 240, an annular spring is used as the elastic member 240, and one end of the ejector pin 230 is inserted into the spring, and the two ends of the spring are respectively in contact with the ejector pin 230 and the conductive area on the circuit board 220. At this time, since the spring and the ejector pin 230 and the conductive area on the circuit board 220 have a large contact area, and the contact part is annular, even if the contact is abnormal at a certain place, it will not affect the overall conductivity, so that a good conductive effect can be achieved.

[0043] At the same time, since the assembly steps of the product are: first install the ejector pin 230 on the bracket 210, then put the microphone silicone 260 on the silicone of the circuit board 220, then put the spring on the ejector pin 230, and finally fix the circuit board 220 on the bracket 210. In the step of fixing the circuit board 220 to the bracket 210, since the ejector pin 230 is covered with a spring, during the process of installing the circuit board 220, the circuit board 220 will press the spring, so that there is always an acting force between the spring and the ejector pin 230 (fixing part 232) and the conductive area of ​​the circuit board 220, thereby maintaining a stable connection relationship, so that there is a stable electrical conduction effect between the ejector pin 230, the spring and the circuit board 220. In addition, when the circuit board 220 is fixed to the bracket 210, the spring buffers the circuit board 220 to prevent excessive pressing force during installation, which may cause abnormal problems such as deformation and cracking of the ejector pin 230, the clamping column 213 and other structures.

[0044] Furthermore, along the thickness direction of the bracket 210, the mounting position 211 is divided into a first mounting position 211a and a second mounting position 211b, that is, the upper half of the mounting position 211 is the first mounting position 211a, and the lower half of the mounting position 211 is the second mounting position 211b, and the cross-sectional area of ​​the first mounting position 211a is greater than the cross-sectional area of ​​the second mounting position 211b, and the second mounting position 211b is between the first mounting position 211a and the circuit board 220, and the ejector pin 230 is inserted into the mounting position 211 from the top of the bracket 210.

[0045] Correspondingly, along the length direction of the ejector pin 230, the fixing portion 232 is divided into a first fixing portion 232a, a second fixing portion 232b and a third fixing portion 232c, the second fixing portion 232b is located between the first fixing portion 232a and the third fixing portion 232c, the first fixing portion 232a is connected to the contact portion 231, and the third fixing portion 232c is connected to the extension portion 233. The first fixing portion 232a and the second fixing portion 232b are located in the first mounting position 211a, the third fixing portion 232c is located in the second mounting position 211b, and the cross-sectional area of ​​the second fixing portion 232b is larger than the cross-sectional areas of the third fixing portion 232c and the first fixing portion 232a, and also larger than the cross-sectional area of ​​the second mounting position 211b.

[0046] Through the above design, after the ejector pin 230 is installed on the bracket 210 , the ejector pin 230 and the installation position 211 have a good matching effect, so that the ejector pin 230 will not shake in the installation position 211 .

[0047] like Figure 8 As shown, in this embodiment, the circuit board 220 is provided with a through hole 221 corresponding to the extension portion 233, the cross-sectional area of ​​the through hole 221 is larger than the cross-sectional area of ​​the extension portion 233, and the extension portion 233 passes through the through hole 221. This design can not only facilitate the installation and alignment of the ejector pin 230, but also enable the ejector pin 230 to pass through the entire spring to prevent the spring from bending and deformation.

[0048] In this embodiment, a metal layer 222 is provided on one side of the circuit board 220 facing the bracket 210 , the metal layer 222 is connected to the circuit on the circuit board 220 , and the metal layer 222 is arranged around the through hole 221 , and the area of ​​the circuit board 220 corresponding to the metal layer 222 forms the conductive area.

[0049] Furthermore, the metal layer 222 and the circuits on the circuit board 220 are simultaneously formed on the plate of the circuit board 220 through a printing process, so as to reduce the production process of the product.

[0050] In other embodiments, it is not necessary to form the through hole 221 at the position corresponding to the ejector pin 230 on the circuit board 220 , and the ejector pin 230 does not need to pass through the circuit board 220 . It is also feasible to have a gap between the bottom of the ejector pin 230 and the circuit board 220 .

[0051] In other embodiments, the elastic member 240 may not be a spring, but may be a conductive elastic structure such as a spring sheet or a spring.

[0052] The above contents are further explanations of the present application in combination with specific optional implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these explanations. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
