Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an electronic atomization device. Background Art

[0002] Electronic atomization device, also known as electronic cigarette, is a device that heats the atomized liquid and atomizes it to generate aerosol for users to inhale in order to simulate the feeling of smoking. As a substitute for tobacco, it is deeply loved by smokers. Common electronic atomization devices mainly include two parts: an atomization component and a power supply component. The atomization component is the core component of the electronic atomization device. It has an oil storage chamber inside. The oil storage chamber is provided with a ventilation pipe and an atomization core. The ventilation pipe is provided with an oil inlet hole connected to the oil storage chamber. When working, the atomized liquid in the oil storage chamber enters the atomization core through the oil inlet hole. The power supply component supplies power to the atomization core. The atomized liquid entering the atomization core is heated and evaporated to generate an aerosol, which is then discharged through the ventilation pipe for users to inhale.

[0003] Before the electronic atomizer device leaves the factory, the atomizer liquid needs to be injected into the oil storage chamber in advance. Usually, the electronic atomizer device is inverted, and then the atomizer liquid is injected into the oil storage chamber from top to bottom. However, the structure of the oil storage chamber in the existing electronic atomizer device is a regular shape, which causes a large amount of atomizer liquid to accumulate near the oil inlet hole after the atomizer liquid is injected, or when the electronic atomizer device is transported upside down, thereby generating a large pressure at the position of the oil inlet hole. The large pressure will cause the atomizer liquid to easily and continuously leak into the ventilation pipe through the oil inlet hole, thereby causing leakage and affecting the user's use. At the same time, as time goes by, the atomizer liquid is in contact with the air for a long time, the atomizer liquid is easy to volatilize, and the taste of the atomizer liquid is easy to deteriorate, which greatly affects the user's suction taste.

[0034] An embodiment of the present application provides an electronic atomization device, which is used to heat an atomization medium stored inside itself to form an aerosol for a user to inhale. When the atomization medium is tobacco oil, the user can simulate the feeling of smoking after inhaling the aerosol formed by the atomization of the tobacco oil, thereby replacing cigarettes and helping the user to quit smoking.

[0035] 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.

[0036] See also Figures 1 to 3 , 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 The 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 one embodiment of the present application includes a shell 100, a bracket 200, an atomization assembly 300 and a power supply assembly 400. Among them, the shell 100 is a hollow structure, the bracket 200, the atomization assembly 300 and the power supply assembly 400 are all arranged in the shell 100, the outer wall of the bracket 200 is attached to the inner wall of the shell 100, and the inner cavity of the shell 100 is divided into an oil storage chamber 103 and a mounting groove 104 that are independent of each other. The atomization assembly 300 is arranged in the oil storage chamber 103, and the power supply assembly 400 is arranged in the mounting groove 104. The shell 100 is provided with an air inlet 101 at one end close to the mounting groove 104, and an air outlet 102 connected to the air inlet 101 is provided at one end close to the oil storage chamber 103.

[0037] Specifically, in one embodiment, the bracket 200 is provided with a plug hole 202 that passes through two opposite sides of the bracket 200 and is connected to the air inlet hole 101. The atomizer assembly 300 includes a ventilation pipe 310 and an atomizer core 320 disposed in the ventilation pipe 310. One end of the ventilation pipe 310 is connected to the air outlet hole 102, and the other end is plugged into the plug hole 202. The side of the ventilation pipe 310 has an oil inlet hole 310a, and the oil inlet hole 310a connects the atomizer core 320 and the oil storage chamber 103. The atomized liquid in the oil storage chamber 103 can enter the atomizer core 320 through the oil inlet hole 310a.

[0038] When the user uses the electronic atomization device 10, by performing a suction action, the external air enters the mounting groove 104 from the air inlet 101, triggering the power supply assembly 400 to work and supply power to the atomization core 320, and the atomization core 320 generates heat to heat the atomized liquid entering its interior, so that the atomized liquid located inside the atomization core 320 is heated and becomes a gaseous aerosol, which is gathered in the ventilation pipe 310 together with the airflow entering the ventilation pipe 310 from the mounting groove 104 and then inhaled into the mouth of the user. At this time, the atomized liquid inside the atomization core 320 is heated and reduced, and the atomized liquid outside the atomization core 320 continues to flow to the inside of the atomization core 320, and the atomized liquid in the oil storage chamber 103 continues to flow into the atomization core 320 through the oil inlet hole 310a.

[0039] Furthermore, the bracket 200 is provided with oil filling holes 201 that penetrate through both sides of the bracket 200. Before the electronic atomization device 10 leaves the factory, the atomized liquid is injected into the oil storage chamber 103 from the oil filling holes 201. The electronic atomization device 10 also includes an oil filling plug 500, which is pluggable and inserted into the oil filling hole 201. When the atomized liquid needs to be injected into the oil storage chamber 103, the oil filling plug 500 can be pulled out from the oil filling hole 201 to inject the atomized liquid; after the atomized liquid is injected into the oil storage chamber 103, the oil filling plug 500 is inserted into the oil filling hole 201 to prevent the atomized liquid from leaking out of the oil filling hole 201.

[0040] However, as described in the background art, usually, the electronic atomization device 10 is inverted, and then the atomized liquid is injected into the oil storage chamber 103 from top to bottom. However, the structure of the oil storage chamber 103 in the existing electronic atomization device 10 is a regular shape, resulting in a large amount of atomized liquid accumulating near the oil inlet hole 310a after the atomized liquid is injected, or when the electronic atomization device 10 is transported inverted, thereby generating a large pressure at the position of the oil inlet hole 310a. The large pressure will cause the atomized liquid to easily and continuously leak into the ventilation pipe 310 through the oil inlet hole 310a, thereby causing the atomized liquid to leak, affecting the user's use. At the same time, as time goes by, the atomized liquid is in contact with the air for a long time, the atomized liquid is easy to volatilize, and the taste of the atomized liquid is easy to deteriorate, which greatly affects the user's suction taste.

[0041] In order to solve this problem, the inventor of the present application has thought that the shape of the oil storage cavity 103 can be designed to be an irregular shape. Specifically, Figure 4 As shown, the bottom wall of the oil storage chamber 103 in the vertical direction (i.e., the Z direction shown in the figure) includes a first plane 203 and a second plane 204 located on the bracket. In the embodiment shown in the figure, the first plane 203 and the second plane 204 are both arranged in the horizontal direction, and the first plane 203 and the second plane 204 have a height difference. The oil inlet hole 310a is located between the first plane 203 and the second plane 204 in the vertical direction. The top wall of the oil storage chamber 103 in the vertical direction includes a third plane 103a located on the inner wall of the shell 100, the oil filling hole 201 is opened in the first plane 203, and the plug hole 202 is opened in the second plane 204. In the vertical direction, the distance between the oil inlet hole 310a and the third plane 103a is greater than the distance between the opening of the oil filling hole 201 on the first plane 204 and the third plane 103a.

[0042] So, like Figure 5As shown, when the electronic atomization device 10 is inverted to inject atomized liquid (that is, the opening of the air hole 102 is vertically downward as shown in the figure), once the user sees that the liquid level of the atomized liquid reaches the first plane 203, the injection of the atomized liquid is stopped. It is through the above-mentioned arrangement that when the electronic atomization device 10 is inverted, the atomized liquid will never contact the oil inlet hole 310a, thereby avoiding the accumulation of a large amount of atomized liquid near the oil inlet hole 310a, and thus no large pressure will be generated near the oil inlet hole 310a, thereby avoiding the leakage of the atomized liquid.

[0043] Specifically, the one side surface of the bracket 200 used to form the oil storage cavity 103 includes a first plane 203 and a second plane 204 with a height difference, which is achieved through the following two embodiments.

[0044] In one embodiment, the bracket 200 includes a main body and a protrusion that are integrally connected. The protrusion is protruded relative to the main body toward the oil storage chamber 103. The protrusion forms a first plane 203 on one side of the oil storage chamber 103, and the main body forms a second plane 204 on one side of the oil storage chamber 103.

[0045] In another embodiment, Figure 4 , Figure 5 and Figure 6 As shown, the first plane 203 is provided with a groove 203a, the bottom wall of the groove 203a forms the second plane 204, and the plug hole 202 is provided on the bottom wall of the groove 203a, that is, it is provided on the second plane 204. It can be clearly seen that, compared with the previous embodiment, in this embodiment, just because the groove 203a is provided on the first plane 203, when the electronic atomization device 10 is placed upright (that is, the opening of the air outlet 102 faces upward), only a small part of the atomized liquid enters the groove 203a and contacts the oil inlet hole 310a, so that there will not be too much atomized liquid accumulated near the oil inlet hole 310a; as mentioned above, when the electronic atomization device 10 is inverted, the atomized liquid will never contact the oil inlet hole 310a. Therefore, the electronic atomization device 10 of this embodiment can avoid a large amount of atomized liquid gathering near the oil inlet hole 310a regardless of whether the electronic atomization device 10 is placed upright or inverted, and can further avoid the formation of a large pressure near the oil inlet hole 310a and the leakage of atomized liquid, thereby achieving better technical effects.

[0046] Of course, it is understandable that the first plane 203 and the second plane 204 can be set at an angle, for example, one or both of the first plane 203 and the second plane 204 are set at an angle relative to the horizontal direction. At this time, the oil inlet hole 310a is not located between the first plane 203 and the second plane 204 in the vertical direction, but as long as it is ensured that in the vertical direction, the distance between the oil inlet hole 310a and the third plane 103a is greater than the distance between the opening of the oil filling hole 201 on the first plane 204 and the third plane 103a, it can be ensured that when the electronic atomization device 10 is inverted, even if the atomized liquid fills the oil storage chamber 103, the atomized liquid will never contact the oil inlet hole 310a.

[0047] Please continue reading Figure 3 and Figure 4 In terms of the structure of the ventilation pipe 310, the ventilation pipe 310 includes an outer tube 311, an oil guide member 312 and an inner tube 313 which are coaxially sleeved from the outside to the inside and staggered in the vertical direction, wherein the outer tube 311, the oil guide member 312 and the inner tube 313 are staggered in the vertical direction, which means that the bottom walls of the outer tube 311, the oil guide member 312 and the inner tube 313 are gradually lowered in the vertical direction. At the same time, the bottom end of the inner tube 313 is plugged into the plug hole 202, and the side wall of the inner tube 313 is provided with at least one oil hole 313a. The atomizer core 320 is arranged in the inner tube 313, and the oil guide member 312 is connected to the atomizer core 320 through the oil hole 313a. The top end of the outer tube 311 is plugged into the air outlet 102, and the bottom end of the outer tube 311 is spaced apart from the second plane 204, so that the bottom end of the outer tube 311 and the second plane 204 form an oil inlet hole 310a surrounding the central axis of the vent pipe 310. The oil guide member 312 is formed by winding a cotton sheet, and is connected to the oil storage chamber 103 through the oil inlet hole 310a, so as to be able to adsorb the atomized liquid, and can guide the atomized liquid entering from the oil inlet hole 310a to the position of the oil hole 313a, so that the atomized liquid can enter the atomizer core 320 through the oil hole 313a.

[0048] Thus, through the above arrangement, the oil inlet hole 310a can be formed without extending the length of the outer tube 311, and there is no need to punch a hole on the tube wall of the outer tube 311, thereby saving materials and simplifying the manufacturing process of the outer tube 311. Moreover, since the formed oil inlet hole 310a surrounds the central axis of the vent hole, the oil inlet hole 310a is also larger, which can ensure that the atomized liquid in the oil storage cavity 103 continuously flows into the oil guide member 312, avoiding insufficient supply of atomized liquid due to the small oil inlet hole 310a. Thus, dry burning can be avoided.

[0049] Furthermore, if Figure 4 and Figure 5As shown, the atomizer core 320 blocks one side of the oil hole 313a (i.e., blocks the inner side of the oil hole 313a), and the oil guide member 312 blocks the other side of the oil hole 313a (i.e., blocks the outer side of the oil hole 313a). This ensures that the atomized liquid in the oil guide member 312 can completely and directly pass through the oil hole 313a into the atomizer core 320, avoiding the atomized liquid from being retained on the wall of the inner tube 313, thereby causing waste of atomized liquid or insufficient atomization.

[0050] Furthermore, in order to further prevent the atomized liquid in the oil storage chamber 103 from leaking, the bottom end of the inner tube 313 is inserted into the plug hole 202 with an interference fit, and the top end of the outer tube 311 is inserted into the air outlet 102 with an interference fit. This ensures that the atomized liquid in the oil storage chamber 103 can be stored in the oil storage chamber 103 in a closed manner. Regardless of whether the electronic atomization device 10 is upright or inverted, the atomized liquid in the oil storage chamber 103 will neither leak from the plug hole 202 nor leak from the air outlet 102.

[0051] It is understandable that the method of preventing leakage of the atomized liquid in the oil storage chamber 103 is not limited to the above-mentioned interference fit method, and sealing can also be achieved by arranging sealing rings on the outer walls of the outer tube 311 and the outer walls of the inner tube 313, which is not limited here.

[0052] Furthermore, when the electronic atomization device 10 is inverted, for example, when the electronic atomization device 10 is inverted for transportation, in order to prevent the atomized liquid in the oil guide member 312 from leaking from the top of the outer tube 311, the top outer wall of the inner tube 313 is also interference fit with the inner wall of the outer tube 311, so as to achieve the purpose of preventing the atomized liquid in the oil guide member 312 from leaking from the top of the outer tube 311.

[0053] In one embodiment, the atomizer core 320 is electrically connected to the power supply assembly 400 through pins. In order to fix the pins and prevent the positive pins and the negative pins from being entangled with each other, refer to Figure 3 and Figure 7 The vent pipe 310 further includes a fixing member 330 inserted into the inner tube 313, the outer circumference of the fixing member 330 is in contact with the inner wall of the inner tube 313, and the outer circumference of the fixing member 330 is provided with a plurality of fixing grooves 330a arranged at intervals around the central axis thereof, each fixing groove 330a passes through opposite ends of the fixing member 330, and the pins are passed through the fixing grooves 330a. In this way, the plurality of pins can be isolated from each other to prevent them from being entangled with each other and causing a short circuit.

[0054] Also, please continue to read Figure 7In order to limit the axial direction of the vent pipe 310 and prevent the vent pipe 310 from moving in its own axial direction, the inner wall of the plug hole 202 also has a plurality of limiting protrusions 202a, which are arranged at intervals around the central axis of the vent pipe 310, and the bottom end of the inner tube 313 abuts against the limiting protrusions 202a, thereby preventing the vent pipe 310 from moving in its own axial direction. Of course, it can be understood that the number of limiting protrusions 202a is not limited, and there can be only one, as long as the vent pipe 310 can be limited in the axial direction, and no specific limitation is made here.

[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.
