Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomization, in particular to an electronic atomizer. BACKGROUND

[0002] The electronic atomizer, also known as electronic cigarette, is a device for generating aerosol by heating and atomizing the atomization medium for users to smoke, so as to simulate the feeling of smoking. As a substitute for cigarettes, the electronic atomizer is very popular among smokers. The traditional electronic atomizer is composed of an atomization assembly and a power supply assembly. The atomization assembly has an oil storage cavity and an atomization core inside. The atomization medium is stored in the oil storage cavity, and the power supply assembly supplies power to the atomization core to heat and atomize the atomization medium in the oil storage cavity to generate aerosol for users to smoke.

[0003] At present, in the traditional electronic atomizer products, the atomization core of some electronic atomizers is a ceramic atomization core. The atomization surface (i.e. the side with heating wires) of the ceramic atomization core is mostly downward. During the atomization process, the atomization surface is downward, and the direction of the mouthpiece is upward. Therefore, the atomization liquid enters the atomization surface downward. After the atomization surface is atomized to generate aerosol, the aerosol is carried to the mouthpiece from the two sides of the atomization core by the reverse airflow, so that the smoke path needs to be bent several times. In this process, the smoke is attenuated, resulting in a decrease in the smoking taste. CONTENT OF THE UTILITY MODEL

[0039] The following will take the electronic atomizer as an example to illustrate the structure of the electronic atomizer in the present application.

It can be understood that in other embodiments, the electronic atomizer of the present application is not limited to an electronic cigarette, but can also be any other electronic atomizer capable of atomizing an atomization medium into an aerosol, which is not limited herein.

[0040] Referring to Figures 1 to 4 , Figure 1 Fig. 1 shows a schematic view of the appearance of an electronic atomizer 10 in an embodiment of the present application, Figure 2 Fig. 2 shows a top view of the electronic atomizer 10, Figure 3 Fig. 3 shows a cross-sectional view of the internal structure of the electronic atomizer 10, Figure 4 Fig. 4 shows an exploded schematic view of the electronic atomizer 10. The electronic atomizer 10 provided in an embodiment of the present application comprises a housing 100, an atomization assembly 200 and a power supply assembly (not shown in the figure), wherein the atomization assembly 200 is arranged in the housing 100 and forms an oil storage cavity 104 with the inner wall of the housing 100 for storing an atomization medium 50, and the power supply assembly is connected to the atomization assembly 200. The power supply assembly is used to supply power to the atomization assembly 200, and the atomization assembly 200 is used to heat the atomization medium 50 flowing into the atomization assembly 200 from the oil storage cavity 104 under the action of the electric energy provided by the power supply assembly, so that the atomization medium 50 can be atomized to generate an aerosol for the user to inhale.

[0041] Specifically, in one embodiment, one end of the housing 100 is open, the atomization assembly 200 is connected to the housing 100 and closes the opening of the housing 100, the end of the housing 100 away from the opening is provided with a mouthpiece 101, the mouthpiece 101 is provided with an air outlet 102 communicating with the inner cavity of the housing 100, and the end of the atomization assembly 200 away from the air outlet 102 is provided with an air inlet 201, so that the air inlet 201 and the air outlet 102 are oppositely arranged and communicate with each other; a ventilation pipe 103 extending from the inner wall of the housing 100 towards the inside of the housing 100 is connected to the inner side of the mouthpiece 101, so that the central axis of the ventilation pipe 103 is parallel to the central axis of the air inlet 201, and the end of the ventilation pipe 103 away from the air outlet 102 is connected to the atomization assembly 200, so that one side of the atomization assembly 200 and the inner wall of the housing 100 form the oil storage cavity 104.

[0042] It can be understood that an oil storage assembly can be additionally arranged in the housing 100, and the oil storage cavity 104 is arranged in the oil storage assembly, which is not limited herein.

[0043] More specifically, in terms of the specific structure of the atomization assembly 200 and the power supply assembly, the power supply assembly comprises a battery, a PCB board connected to the battery, and an airflow sensor connected to the PCB board, etc., which can be specifically referred to the prior art, and will not be described here again. The structure of the atomization assembly 200 will be described in detail below.

[0044] In combination Figure 3 And Figure 5 As shown in FIG. 1, in one embodiment, the inner part of the ventilation pipe 103 is formed with an airflow passage 103a extending through both ends thereof and communicating with the air inlet 201 and the air outlet 102, the atomization assembly 200 is provided with an atomization cavity 202, the atomization cavity 202 is in communication with the air outlet 102 through the airflow passage 103a, and the sidewall of the atomization cavity 202 is provided with a mounting groove 203, the mounting groove 203 is provided with an atomization core 210 electrically connected to the power supply assembly, the opposite sides of the atomization core 210 are respectively provided with an atomization surface 211 and an oil inlet surface 212 oppositely arranged, the atomization surface 211 faces the atomization cavity 202, so that the plane on which the atomization surface 211 is located is parallel to the central axis of the ventilation pipe 103, and the oil inlet surface 212 faces away from the atomization cavity 202 and is in communication with the oil storage cavity 104.

[0045] When the user performs a suction action to make the atomization core 210 electrically conductive with the power supply assembly, the atomization medium 50 flows from the oil storage cavity 104 to the oil inlet surface 212, and then flows to the atomization surface 211 from the oil inlet surface 212, while the atomization core 210 is working, the atomization medium 50 flowing to the atomization surface 211 is heated, so that the atomization medium 50 generates aerosol in the atomization cavity 202, external air enters the atomization cavity 202 from the air inlet 201, mixes with the aerosol, and then directly enters the airflow passage 103a, and then is inhaled by the user from the air outlet 102.

[0046] In this way, as can be seen from the figure, through the above design, the structure of the atomization cavity 202 is simple, the air inlet 201 can directly pass through the airflow passage 103a in the ventilation pipe 103 through the atomization cavity 202, and the airflow entering the atomization cavity 202 from the air inlet 201 can directly bring the aerosol generated in the atomization cavity 202 into the airflow passage 103a and finally to the mouthpiece 101 with fewer bending times, thereby reducing the loss of smoke during the suction process, and further improving the taste of the smoke when the user inhales, thereby improving the suction taste of the user.

[0047] As one of the embodiments, the atomization core 210 is a ceramic core, that is, the heating body material of the atomization core 210 is ceramic. The use of ceramic can make the atomized aerosol particles smaller, the aerosol experience more delicate, and the durability and service life longer, which can better resist high temperature and chemical corrosion. Of course, the material of the oil guide body is not limited to ceramic, but can also be oil guide cotton and other materials, which is not limited here.

[0048] It is worth noting that during the atomization process, the aerosol will inevitably produce condensate after cooling. In order to have space to accommodate the condensate and adsorb the condensate, prevent the condensate from leaking out of the atomization assembly 200 to contact the power supply assembly to cause short circuit, in a preferred embodiment, the atomization assembly 200 is also provided with an oil absorption cavity 204 communicating with the atomization cavity 202, and the oil absorption cavity 204 is provided with an oil absorption cotton 220, which is used to absorb the condensate generated in the atomization cavity 202, so that the leakage of a large amount of condensate out of the atomization assembly 200 can be prevented to a certain extent.

[0049] It is also worth noting that since the air inlet 201 is directly connected to the airflow passage 103a, in order to reduce the leakage of the condensate flowing back from the airflow passage 103a from the air inlet 201, as shown in Figure 5 , the end of the air inlet 201 facing the atomization cavity 202 has a bottom wall 205, and the bottom wall 205 is provided with a plurality of air passing holes 206, and the air inlet 201 communicates with the atomization cavity 202 through the plurality of air passing holes 206. As can be seen, because of the existence of the bottom wall 205, even if there is condensate flowing back from the airflow passage 103a, the bottom wall 205 can block the condensate flowing back to a certain extent, so that the leakage of the condensate flowing back from the air inlet 201 can be reduced. Preferably, the air inlet 201 is protrudingly arranged towards the atomization cavity 202.

[0050] Further, in order to completely prevent the condensate flowing back from leaking out of the air inlet 201, the atomization cavity 202 is provided with a separation piece 230, which is substantially "L" shaped and includes a body 231 and a separation portion 232 connected to the body 231 and partially protruding from the body 231. The projection of the separation portion 232 on the cross section of the air inlet 201 covers the air inlet 201, and the projection of the separation portion 232 on the cross section of the airflow passage 103a at least partially covers the airflow passage 103a. In this way, if the condensate in the airflow passage 103a flows back and drips down, the separation portion 232 can block the condensate flowing back from dripping into the air inlet 201, so that the condensate can be completely prevented from leaking out of the air inlet 201.

[0051] As shown in Figure 5 , Figure 6 , Figure 7 and Figure 8 , the part of the separation portion 232 protruding from the body 231 has a flow guiding surface 2321 inclined towards the oil absorption cavity 204 on the side facing the airflow passage 103a, and the plane where the flow guiding surface 2321 is located is inclined relative to the horizontal direction. Alternatively, in addition to being inclined towards the oil absorption cavity 204, the flow guiding surface 2321 is also inclined upwards towards the direction of the air outlet 102 (as shown in Figure 5The condensate drops falling to the isolation portion 232 will flow along the flow guide surface 2321 to the oil absorption cotton 220 under the action of gravity, and particularly when the flow guide surface 2321 is upwardly inclined toward the direction of the air outlet 102, the condensate drops will first flow along the flow guide surface 2321 to the oil absorption cotton 220 under the action of gravity, and then flow into the oil absorption cotton 220, thereby avoiding the condensate from being deposited on the isolation portion 232 and keeping the isolation portion 232 clean. Figure 4 The condensate drops falling to the isolation portion 232 will flow along the flow guide surface 2321 to the oil absorption cotton 220 under the action of gravity, and particularly when the flow guide surface 2321 is upwardly inclined toward the direction of the air outlet 102, the condensate drops will first flow along the flow guide surface 2321 to the oil absorption cotton 220 under the action of gravity, and then flow into the oil absorption cotton 220, thereby avoiding the condensate from being deposited on the isolation portion 232 and keeping the isolation portion 232 clean.

[0052] In a preferred embodiment, in combination with the embodiments shown in Figure 5 , Figure 7 and Figure 8 , the side of the isolation portion 232 facing the airflow channel 103a has a gas guide surface 2322 inclined toward the airflow channel 103a, and the plane of the gas guide surface 2322 is also inclined relative to the horizontal direction. Since the gas guide surface 2322 is inclined toward the airflow channel 103a, the gas guide surface 2322 can play a guiding role to concentrate the airflow entering from the air inlet 201 to a position close to the atomization surface 211, so that the airflow is more concentrated, thereby enabling the smoke flow after the airflow is mixed with the aerosol to be larger, so that the user can have a better smoking experience when smoking.

[0053] Please refer to Figure 3 , Figure 4 and Figure 6 for the more specific structure of the atomization assembly 200. In addition to the atomization core 210, the atomization assembly 200 further includes a heating seat 240 and a heating cover 250. One end of the heating seat 240 closes the opening of one end of the shell 100, and the heating cover 250 is connected to the air pipe 103 and covers the other end of the heating seat 240. The heating seat 240 and the heating cover 250 are both open-ended shell 100 structures. The side surface of the heating cover 250 facing the heating seat 240 and the inner wall of the heating seat 240 together form the atomization chamber 202 and the oil absorption chamber 204. The side of the heating cover 250 away from the heating seat 240 and the inner wall of the shell 100 together form the oil storage chamber 104. The air inlet 201 is provided at the bottom end of the heating seat 240, and the mounting groove 203 is provided at the side surface of the heating cover 250 to form the atomization chamber 202.

[0054] Further, please refer to Figure 5 In one embodiment, the heating cover 250 is provided with a first oil guiding channel 251 extending through opposite sides of the heating cover 250, and the second oil guiding channel 252 is provided in the slot wall of the installation slot 203 and is in communication with the first oil guiding channel 251. The oil storage cavity 104 is in communication with the oil inlet surface 212 of the atomization core 210 through the first oil guiding channel and the second oil guiding channel.

[0055] Preferably, the central axis of the second oil guiding channel 252 is perpendicular to the plane on which the atomization surface 211 is located; more preferably, the first oil guiding channel 251 extends in the vertical direction as shown in Figure 5 , and the second oil guiding channel 252 extends in the horizontal direction as shown in Figure 4 , so that the first oil guiding channel 251 and the second oil guiding channel 252 are perpendicular to each other, and thus are configured as an "L" shape.

[0056] Through the above arrangement, when the electronic atomizer 10 is placed vertically, the atomization medium 50 will not flow directly and too quickly into the atomization core 210 in the vertical direction, but will first flow to the second oil guiding channel 252 in the vertical direction, and then flow to the oil inlet surface 212 of the atomization core 210 in the horizontal direction, thereby avoiding the situation that the atomization medium 50 in the oil storage cavity 104 penetrates into the installation slot 203 or the atomization cavity 202 too quickly due to gravity, causing liquid leakage or seepage.

[0057] Of course, the shape formed by the first oil guiding channel 251 and the second oil guiding channel 252 is not limited to an "L" shape, but can also be any bending or curved shape, as long as it can prevent the atomization medium 50 from flowing into the atomization core 210 too quickly.

[0058] Please refer to Figure 3 , in order to prevent the atomization medium 50 in the oil storage cavity 104 from leaking out of the electronic atomizer 10 through the gap between the atomization assembly 200 and the shell 100, a sealing silica gel 260 is sleeved on the heating cover 250. On this basis, in order to avoid the situation that the atomization medium 50 in the oil storage cavity 104 leaks out of the electronic atomizer 10 through the gap between the atomization assembly 200 and the shell 100 in the extreme case, such as when the sealing silica gel 260 is damaged or the sealing is not tight, a sealing ring 300 is provided between the heating seat 240 and the inner wall of the shell 100, which blocks the gap between the heating seat 240 and the inner wall of the shell 100, and has a double sealing guarantee together with the sealing silica gel 260.

[0059] Further, if the sealing of the sealing silica gel 260 is not tight, in order to collect the leaked atomization medium 50 and guide the atomization medium 50 to the oil absorption cavity 204 to be absorbed by the oil absorption cotton 220, in combination with Figure 4 andFigure 7 As shown, the outer side wall of the heating cover 250 is provided with a first flow channel 253, and the side surface of the heating cover 250 that forms the oil absorption cavity 204 with the heating base 240 is provided with a second flow channel 254. One end of the first flow channel 253 is communicated with the oil storage cavity 104, and the second flow channel 254 is communicated with the first flow channel 253 and the oil absorption cavity 204.

[0060] In this way, if the atomization medium 50 leaks out of the oil storage cavity 104, the atomization medium 50 can be guided into the oil absorption cavity 204 by the first flow channel 253 and the second flow channel 254 and be adsorbed by the oil absorption cotton 220, and the phenomenon of oil leakage can be further avoided.

[0061] Further, in a preferred embodiment, as shown in Figure 9 The first flow channel 253 is bent and extends, so that the atomization liquid that leaks out of the oil storage cavity 104 can be slowly guided to the second flow channel 254, slowing down the speed of the atomization medium 50 leaking out. More preferably, as shown in Figure 10 The second flow channel 254 includes a main channel 2541 and a plurality of sub-channels 2542 communicated with the main channel 2541. The main channel 2541 has an oil inlet 2541a communicated with the first flow channel 253, and each sub-channel 2542 has an oil outlet 2542a communicated with the oil absorption cavity 204. The purpose of this design is that if more atomization medium 50 has leaked into the second flow channel 254, the atomization medium 50 can be guided into the oil absorption cavity 204 as soon as possible by setting multiple oil outlets 2542a, so as to avoid too much atomization medium 50 deposited in the second flow channel 254 from leaking out of the gap between the heating cover 250 and the heating base 240.

[0062] It can be understood that the structure composed of the heating cover 250 and the heating base 240 can also be an integrally formed structure, but the design of the detachable structure can facilitate the installation of the atomization core 210 or the oil absorption cotton 220, which is obviously the best embodiment.

[0063] In addition, referring to Figure 3 and Figure 6 In terms of the electrical connection between the atomization core 210 and the power supply assembly, in one embodiment, the heating base 240 is further provided with a thimble 400, and the power supply assembly is electrically connected to the atomization core 210 through the thimble 400. Specifically, in the embodiment shown in the figure, the thimble 400 has two, and the two thimbles 400 represent the positive and negative electrodes respectively. One end of each thimble 400 extends into the atomization cavity 202 and contacts the atomization surface 211 of the atomization core 210, and the other end is electrically connected to the power supply assembly. The extension direction of each thimble 400 is parallel to the atomization surface 211, thereby realizing the electrical connection between the atomization core 210 and the power supply assembly.

[0064] In the mounting sequence of the electronic atomizer 10 provided in the present application, first, the atomizing core 210 is loaded into the heating cover 250, and then the sealing silica gel 260 is loaded into the heating cover 250; then the thimble 400 is pressed into the heating seat 240, the oil absorbing cotton 220 is loaded into the heating seat 240, the sealing ring 300 is sleeved on the outer peripheral surface of the heating seat 240, and then the heating cover 250 is buckled into the heating seat 240 to form the atomizing assembly 200; finally, the atomizing assembly 200 is buckled into the shell 100, the atomizing medium 50 is injected into the oil storage cavity 104, and the power supply assembly is connected to the thimble 400, and the assembly of a complete electronic atomizer 10 is completed.

[0065] In summary, when the electronic atomizer 10 provided in the present application is smoked, compared with the structure that the atomizing surface 211 faces downward in the conventional electronic atomizer 10, the structure that the air inlet 201 is straight through the airflow channel 103a and the atomizing surface 211 faces the atomizing core 210 makes the smoke attenuation loss much less, and further makes the taste of the atomized smoke more pure, and the aroma, sweetness and taste performance are also more outstanding, thereby bringing a better smoking experience to the user.

[0066] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0067] The above-described embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
