Description

[0002] Electronic atomization device, also known as electronic cigarette, is a device that heats and atomizes atomized liquid to generate aerosol for users to inhale to simulate the feeling of smoking. As a substitute for cigarettes, it is deeply loved by smokers. The traditional electronic atomization device consists of an atomization unit and a power supply unit, wherein the atomization unit has an oil storage chamber inside, and the atomization medium is stored in the oil storage chamber. The power supply unit supplies power to the atomization unit, heats and evaporates the atomization medium in the oil storage chamber to generate aerosol for users to inhale.

[0003] However, in existing electronic atomization devices, the atomization unit and the power supply unit are generally designed as an integrated whole. As the name implies, the integrated atomization unit and the power supply unit are disposable. When the atomized medium is exhausted after suction, the entire electronic atomization device needs to be discarded, which causes waste and leads to high costs. In addition, in existing replaceable electronic atomization devices, the atomization unit and the power supply unit are usually designed from top to bottom, but the overall size of this structure is relatively long and the volume is relatively large.

[0037] An embodiment of the present application provides an electronic atomization device, which is used to heat an atomization medium stored inside the electronic atomization device to form an aerosol for inhalation by a user.

[0038] The following uses the electronic atomization device as an electronic cigarette as an example to illustrate the structure of the electronic atomization device in the present application. This embodiment is only used as an example and does not limit the technical scope of the present application. It can be understood that in other embodiments, the electronic atomization device of the present application is not limited to an electronic cigarette, but can also be any other electronic atomization device that can atomize the atomization medium into an aerosol, which is not limited here.

[0039] See also Figures 1 to 4 , Figure 1 and Figure 2 FIG. 1 shows a schematic diagram of the appearance of an electronic atomization device 10 in an embodiment of the present application. Figure 3 and Figure 4 A cross-sectional view of the internal structure of the electronic atomization device 10 in this embodiment is shown. The electronic atomization device 10 provided in an embodiment of the present application includes an atomization unit 100 and a power supply unit 200, wherein the atomization unit 100 is provided with a recessed mounting position 101 on one side in its thickness direction, and a contact electrode 110 is provided on the bottom wall of the mounting position 101. The power supply unit 200 is partially or completely accommodated in the mounting position 101 and is detachably fixedly connected to the atomization unit 100. The power supply unit 200 has a spring pin 210 on one side close to the atomization unit 100, and the spring pin 210 abuts against the contact electrode 110, so that the power supply unit 200 and the atomization unit 100 are electrically connected to each other. The atomization unit 100 is provided with an air inlet 102 and an air outlet 103. When the user uses the electronic atomization device 10, by performing a suction action, external airflow enters the atomization unit 100 from the air inlet 102, and triggers the power supply unit 200 to supply power to the atomization unit 100, so that the atomization unit 100 heats and atomizes the atomization medium stored inside itself to generate aerosol, which is mixed with the airflow entering from the air inlet 102 and then discharged from the air outlet 103 for the user to inhale.

[0040] It is understandable that the power supply unit 200 and the atomization unit 100 can be fixedly connected to each other by magnetic attraction or by removably engaging each other, which is not limited here. By designing the atomization unit 100 and the power supply unit 200 as a detachable modular structure, the atomization unit 100 and the power supply unit 200 are easy to assemble, and the atomization unit 100 can be replaced separately after the atomization medium in the atomization unit 100 is consumed, thereby reducing waste, reducing the production and manufacturing costs of the electronic atomization device 10, and reducing the risk of the entire machine being scrapped due to local damage to electronic components, thereby extending the life of the product; and it also enables the length dimension of the electronic atomization device 10 to be greatly reduced.

[0041] In a specific embodiment, Figure 5 As shown, the power supply unit 200 includes a power supply unit housing 220, a battery 230 and a circuit board 240. The battery 230 and the circuit board 240 are accommodated in the power supply unit housing 220 and are electrically connected to each other. The spring pin 210 is arranged on the circuit board 240 and partially exposed from the power supply unit housing 220. In order to fix the circuit board 240, in a preferred embodiment, as shown in FIG. Figure 6 As shown, the power supply unit shell 220 includes an upper shell 221 and a lower shell 222 of the power supply unit. The inner wall of the lower shell 222 of the power supply unit is provided with a first fixing column 2221, and a second fixing column 2211 is provided on the inner wall opposite to the upper shell 221 and the lower shell 222 of the power supply unit. The circuit board 240 is provided with a through hole passing through the opposite sides of itself, the first fixing column 2221 is penetrated by the through hole, and the second fixing column 2211 is coaxially connected to the first fixing column 2221 to fix the circuit board 240 in the power supply unit shell 220.

[0042] exist Figure 6 In the embodiment shown in , the connection structure between the second fixing column 2211 and the first fixing column 2221 is a mutually plug-in structure, that is, the diameter of the second fixing column 2211 is larger than the diameter of the first fixing column 2221, the second fixing column 2211 is provided with a plug-in hole 2211a, the first fixing column 2221 is plugged into the plug-in hole 2211a, and the opposite side walls of the circuit board 240 are respectively abutted against the end of the second fixing column 2211 and the inner wall of the lower shell 222 of the power supply unit, so that the circuit board 240 can be fixedly installed in the power supply unit shell 220 without screws, thereby facilitating assembly, saving materials, and improving assembly efficiency.

[0043] Of course, it is understandable that in other embodiments, the structure of the power supply unit shell 220 can also be an integrally molded structure, and the first fixing column 2221 and the second fixing column 2211 are respectively arranged on the two opposite inner walls of the power supply unit shell 220, and the second fixing column 2211 can also be passed through the through hole of the circuit board 240, and the second fixing column 2211 is inserted into the first fixing column 2221, which is not limited here.

[0044] Further, in order to enable the user to trigger the power supply unit 200 to work while performing the suction action, please continue to refer to Figure 5 The power supply unit 200 further includes an airflow sensor 250 disposed in the power supply unit housing 220 and electrically connected to the circuit board 240. Figure 7 As shown, the air inlet 102 and the air outlet 103 are provided at opposite ends of the atomizing unit 100, and the atomizing unit 100 has an air flow channel 104, through which the air inlet 102 and the air outlet 103 are connected to each other, and the air flow sensor 250 is installed at one end of the power supply unit housing 220 close to the air outlet 103 and connected to the air outlet 103. In this way, when the user inhales, the air passing through the air flow channel 104 from the air inlet 102 and entering the air outlet 103 will generate negative pressure, so that the air flow sensor 250 can sense the air flow and trigger the power supply unit 200 to work. In addition, by installing the air flow sensor 250 at one end of the power supply unit housing 220 close to the air outlet 103, the air flow sensor 250 can also sense the air flow more sensitively, thereby improving the working sensitivity of the air flow sensor 250.

[0045] In the structure of the atomizing unit 100, Figure 5 and Figure 7 As shown, the atomization unit 100 includes an atomization unit housing 110, an atomization assembly 120 and a nozzle 130, wherein the atomization assembly 120 is arranged in the atomization unit housing 110, the nozzle 130 is connected to one end of the atomization unit housing 110 and connected to the atomization assembly 120, the air inlet 102 is opened on the atomization unit housing 110, the air outlet 103 passes through the nozzle 130, and the air flow channel 104 passes through the atomization assembly 120; the mounting position 101 is opened on one side of the atomization unit housing 110, combined with Figure 3 and Figure 8 As shown, a vent hole 106 is formed on the bottom wall of the mounting position 101, and a vent groove 130a connected to the air outlet 103 is formed at one end of the nozzle 130 close to the atomizer assembly 120. The air flow sensor 250 is connected to the air outlet 103 via the vent hole 106 and the vent groove 130a in sequence.

[0046] See also Figure 8In a preferred embodiment, the inner wall of the atomizing unit housing 110 is provided with a positioning column 1111 connected to the atomizing assembly 120, and the vent hole 106 passes through the positioning column 1111. More specifically, as Figure 7 As shown, the atomizer assembly 120 includes an oil tank 121, a first seal 122, a second seal 123, a vent pipe 124 and an atomizer core 125, wherein the oil tank 121 is a cylindrical hollow shell, the first seal 122 and the second seal 123 are respectively made of silicone material, and the two are respectively arranged at opposite ends of the oil tank 121 and close the opposite end openings of the oil tank 121 to prevent leakage of the atomized medium; the vent pipe 124 is penetrated in the oil tank 121, and its opposite ends are respectively inserted in the first seal 122 and the second seal 123, the air flow channel 104 runs through the vent pipe 124, and the atomizer core 125 is arranged in the air flow channel 104 and is electrically connected to the contact electrode 110 through a wire connection or the like, as shown in FIG. Figure 8 As shown, the nozzle 130 is connected to the second sealing member 123 with interference fit, the positioning column 1111 is inserted into the second sealing member 123 with interference fit, and the vent hole 106 is connected to the vent groove 130a of the nozzle 130 through the cavity 140a in the second sealing member 123.

[0047] In this way, the atomizer assembly 120 can be fixed to the atomizer unit shell 110, and the positioning column 1111 is inserted in the second sealing member 123. When the user inhales to generate negative pressure and the air flows through the ventilation groove 130a and the ventilation hole 106, the air will not leak from the connection gap between the atomizer unit shell 110 and the atomizer assembly 120, thereby not affecting the sensing accuracy of the airflow sensor 250.

[0048] Recombination Figure 3 and Figure 7 As shown, similar to the power supply unit housing 220, the atomization unit housing 110 can also be designed as a detachable structure, which includes an atomization unit upper housing 111 and an atomization unit lower housing 112, the mounting position 101 is provided on the side of the atomization unit upper housing 111 away from the atomization unit lower housing 112, the positioning column 1111 is provided on the inner wall of the atomization unit upper housing 111, and the air inlet 102 and the air outlet 103 are provided on the atomization unit lower housing 112. Of course, the atomization unit housing 110 can also be an integrally formed structure, and there is no special limitation on this.

[0049] Furthermore, in one embodiment, if Figure 7As shown, in the direction from the air inlet 102 to the air outlet 103, the air flow channel 104 and the air outlet 103 are staggered. In other words, in the direction from the air inlet 102 to the air outlet 103, the air flow channel 104 and the air outlet 103 are not on the same straight line. The purpose of such design is to make the internal structure of the atomization unit 100 compact and avoid interference between the internal components of the atomization unit 100. However, there is a problem with such design, that is, there is a 90° corner between the air flow channel 104 and the air outlet 103, which will cause the air flow to be not smooth enough, affecting the user's smoking taste.

[0050] In order to overcome this problem, in a preferred embodiment, a transition space 105 connected to the air outlet 103 is further provided in the suction nozzle 130. The transition space 105 is provided at one end of the air outlet 103 close to the air flow channel 104 and connected to the air flow channel 104. Figure 7 As shown, the transition space 105 is a cone-like columnar space structure, so that the inner diameter of the transition space 105 and the air outlet 103 added together is larger than the inner diameter of the air flow channel 104, so that the corner between the air flow channel 104 and the transition space 105, and the corner between the transition space 105 and the air outlet 103 are not 90 degrees. After the airflow flows out of the air flow channel 104, before entering the air outlet 103, it can be buffered in the transition space 105, and the phenomenon of unsmooth flow of the airflow will not occur.

[0051] It is worth noting that when the electronic atomization device 10 is designed, some parts are standard parts and their sizes are fixed and cannot be easily changed. Figure 5 As shown in FIG. 1 , there is a certain distance between the first sealing member 122 and the air inlet 102, so that there is a large gap between the first sealing member 122 and the air inlet 102. When the user inhales, a large vortex is generated when the airflow enters the gap from the air inlet 102. Under the action of the vortex, the user generates a large airflow noise when inhaling. In order to solve this problem, in an improved embodiment, combined with Figure 5 and Fig. 9 As shown, a bracket 140 is also provided in the atomization unit shell 110, and the bracket 140 is connected to one end of the atomization assembly 120 close to the air inlet 102, specifically connected to the first sealing member 122, and the bracket 140 has a cavity connected to the air flow channel 104, and the bracket 140 is provided with an air hole 141 and a silencer hole 142, the air inlet 102 is connected to the air hole 141 and the silencer hole 142, and the air hole 141 is connected to the silencer hole 142 through the cavity in the bracket 140.

[0052] Thus, on the one hand, the bracket 140 fills the gap between the atomizer assembly 120 and the air inlet 102. On the other hand, the airflow can enter the cavity 140a in the bracket 140 not only from the air hole 141, but also from the muffler hole 142, thus preventing the airflow from generating vortex in the bracket 140, thereby reducing the airflow noise generated during inhalation.

[0053] In addition, in order to display the remaining amount of atomizing medium in the atomizing unit 100, a display screen (not shown in the figure) for displaying the remaining amount of atomizing medium is also provided in the power supply unit 200. The display screen is communicatively connected to the circuit board 240. When the atomizing medium decreases, the remaining amount of atomizing medium displayed on the display screen will also decrease accordingly. However, since the atomizing unit 100 and the power supply unit 200 are detachable structures, when the atomizing medium in the atomizing unit 100 is exhausted and a new atomizing unit 100 is replaced, the value displayed on the display screen is still zero, which will cause the remaining amount of atomizing medium to be displayed inaccurately. Therefore, in order to correct the remaining amount of atomizing medium displayed on the display screen so that the actual remaining amount of atomizing medium in the atomizing unit 100 can be correctly displayed again, refer to Figure 4 The power supply unit 200 also includes a reset button 260 disposed on the power supply unit housing 220. The reset button 260 is connected to the circuit board 240 and is used for a user to press so that when the atomization unit 100 is replaced with an atomization unit 100 filled with atomization medium, the remaining amount of atomization medium in the atomization unit 100 can be correctly displayed again.

[0054] It can be seen that the electronic atomization device provided by the present application has a novel structure and is easy to assemble compared to the traditional structure in which the atomization unit and the power supply unit are arranged up and down. The length of the electronic atomization device is greatly reduced. When the user puts the electronic atomization device into a pocket or pocket to carry it with him, the electronic atomization device is not easy to slip, and the nozzle is not easy to be exposed to the external environment for a long time, which can effectively improve the user's experience. And by designing the internal structure, when the user is inhaling, the airflow sensor is sensitive, the airflow is smooth, the airflow noise is small, and the user can have a better suction taste.

[0055] Finally, it should be noted that the various technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the various 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.

[0056] 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.
