The technical solution of the present invention is further explained by the following embodiments with reference to the drawings.

Fig. 1 is an exploded schematic view of an atomizing device according to an embodiment of the present invention. As shown in fig. 1, the atomization device includes a housing 1, a first seal portion 2, a transition portion 3, an atomization portion 4, and a second seal portion 5.

Fig. 2 is a side sectional view of a housing of an atomizing device according to an embodiment of the present invention. As shown in fig. 2, the housing 1 includes an upper case 101 and a lower case 102, the upper case 101 being located at one end of the housing 1, and the lower case 102 being located at the other end of the housing 1. The oil storage chamber 11 is provided inside the upper case 101, and the atomizing area 4 is provided inside the lower case 102. That is, the lower case 102 has a shape matching the upper case 101 so as to be embedded in the upper case 101 such that the housing 1 forms one body. In the present embodiment, the upper casing 101 and the lower casing 102 are arranged from top to bottom along the vertical direction, the lower casing 102 extends into the upper casing 101, and the two are directly connected by the corresponding structure at the edge, so that the casing 1 is formed into a column with a cross section similar to an ellipse. Alternatively, the lower shell 102 and the upper shell 101 may have other connecting manners, and the housing 1 may have other shapes.

Further, the housing 1 further includes a third sealing portion 6, and the third sealing portion 6 is configured to seal the housing 1. In the present embodiment, the third sealing portion 6 is formed as a sealing ring, and is inserted between the lower case 102 and the upper case 101 to perform a sealing function. Since the third seal portion 6 can also provide a certain frictional force, it can play a certain role of fixing the upper case 101 and the lower case 102 to each other. Alternatively, the third sealing portion 6 may have other arrangements, for example, when the lower casing 102 does not extend into the upper casing 101, but the cover and the upper casing 101 are formed to be connected to each other by a screw or other means, the third sealing portion 6 may be formed as a sealing ring embedded in the lower casing 102, abutting against the edge of the upper casing 101 to achieve a sealing effect.

Fig. 3 is a schematic perspective view of a transition portion of an atomization device according to an embodiment of the present invention. Fig. 4 is a side sectional view of a transition portion of an atomizing device according to an embodiment of the present invention. Fig. 5 is a side sectional view of an atomizing device according to an embodiment of the present invention. As shown in fig. 3, 4 and 5, in order to achieve the function of sucking air for the user, the inside of the atomization device needs to have an air passage, i.e., an air passage B, so that the atomization portion 4 can communicate with the external environment.

The upper case 101 has an air outlet passage B1 formed as an air outlet hole 12, and the lower case 102 has an air inlet passage B2 formed as an air inlet hole 13. That is, during use by a user, outside air enters the housing 1 through the air inlet holes 13 and is discharged or sucked out of the housing 1 through the air outlet holes 12. Wherein, because the transition portion 3 plays the transition effect at venthole 12 and inlet port 13, the transition portion 3 is provided with first through-hole 31. In the present embodiment, the air outlet hole 12 is formed in a pipe-like structure extending inside the housing 1, and the oil reservoir chamber 11 is provided on both sides of the air outlet hole 12. The duct of the outlet hole 12 protrudes from the transition portion 3 by being fitted into the first through hole 31, so that the outlet passage B1 and the inlet passage B2 communicate with each other to constitute the air passage B. The air in the air passage B flows in the direction of entering the housing 1 through the air inlet 13 and then entering the air outlet 12 through the first through hole 31. Alternatively, the outlet holes 12 may have other arrangements. Meanwhile, the air intake holes 13 are provided as two through holes at the bottom of the housing 1. Alternatively, the outlet holes 12 may have other arrangements, or have other numbers.

Further, the transition portion 3 has a boss 32, and the boss 32 is opposed to the first through hole 31 to form an air guide passage B3 extending in the horizontal direction. Because the atomizing part 4 set up in the transition portion 3, transition portion 3 plays the transition effect between oil storage chamber 11 and atomizing part 4, and the atomizer 41 of atomizing part 4 sets up in boss 32 bottom, and second sealing 5 butt is between boss 32 and atomizing part 4. Therefore, the boss 32 provided at the position opposite to the first through hole 31 can provide the space for providing the atomizing part 3, making the atomizing device more compact. Since the transition portion 3 is disposed around the duct of the outlet hole 12 through the first through hole 31, the air needs to pass through the transition portion 3 while propagating in the air passage B. Therefore, the provision of the bosses 32 also enables the path through which air circulates to be changed, that is, the air guide passage B3 formed to communicate with the air outlet passage B1 and the air inlet passage B2 with each other, as a part of the air passage B.

In the present embodiment, the boss 32 is provided with a rounded corner 321 to form the air passage B into a smooth shape for easy air circulation. That is, when air flows from the air inlet passage B2 to the air guide passage B3, the rounded corners 321 of the bosses 32 make it easier for smoke to enter the air outlet passage B1 through the air guide passage B3, and prevent smoke generated by atomization of smoke from flowing smoothly at the air guide passage B3 as the air rises, thereby generating a condensate affecting function. Further, in the present embodiment, the rounded corners 321 are disposed at both ends of the boss 32 in the horizontal direction, and form an arc together with the inner walls of both sides of the boss 32, alternatively, the rounded corners 321 may have other disposition manners.

Fig. 6 is a schematic perspective view of a first sealing portion of an atomization device according to an embodiment of the present invention. Fig. 7 is a schematic perspective view of a second sealing portion of an atomizing device according to an embodiment of the present invention. As shown in fig. 6 and 7, the first sealing portion 2 is disposed at the bottom of the oil storage chamber 11, and is sleeved on the upper end of the transition portion 3 and disposed between the transition portion 3 and the housing 1. The second sealing portion 5 is disposed between the transition portion 3 and the atomizing portion 4.

Fig. 8 is a front sectional view of an atomizing device according to an embodiment of the present invention. Fig. 9 is a partial schematic view of a front cross-sectional view of an atomizing device in accordance with an embodiment of the present invention. As shown in fig. 8 and 9, in order to realize the function of atomizing the tobacco tar stored in the oil storage chamber 11 by the atomizing unit 4, a tobacco tar channel 34 is provided inside the atomizing device, so that the tobacco tar can contact the atomizing unit 4 and be further atomized to form smoke.

Since the transition portion 3 is provided between the oil storage chamber 11 and the atomizing portion 4 which are arranged in the vertical direction, the transition portion 3 is made to include the soot passage 34 formed as a through hole extending in the vertical direction, so that the atomizing portion 4 and the oil storage chamber 11 communicate with each other through the soot passage 34. The first sealing portion 2 and the second sealing portion 5 respectively include a second through hole 22 and a third through hole 51 corresponding to the position of the soot passage 34. That is, the smoke in the oil reservoir 11 passes through the first through hole 31 of the first seal portion 2, the smoke passage 34, and the second through hole 22 of the second seal portion 5, and contacts the atomizer 4, that is, flows to the surface of the atomizer 41 fitted to the bottom of the boss 32.

Further, the atomizing area 4 includes an atomizer 41 and a heating element 42, and the heating element 42 is partially exposed from the lower case 102 to be electrically connected to an external power source. In the present embodiment, the atomizer 41 faces the third through hole 51 of the second seal portion 5, thereby contacting the soot flowing through the soot channel 34. Since the atomizer 41 is usually made of a ceramic body, the inside of the ceramic body has a large number of capillary pores, so that the tobacco tar can penetrate downward from the ceramic body and reach the bottom surface, i.e., the atomizing surface, of the atomizer 41, and is heated and atomized by the heating element 42. Meanwhile, the tobacco tar has certain viscosity, the liquid has certain tension due to the nature of the liquid, and the tobacco tar cannot seep out of the atomizer 41 under the condition of extremely small capillary pores. Moreover, since the atomizing part 4 is partially disposed in the air passage B, that is, the bottom surface of the atomizer 41 where the atomization reaction occurs is located in the air passage B, the smoke generated by the atomization of the tobacco tar flows along with the air in the air passage B for the user to suck.

In order to prevent the smoke from seeping out from the smoke channel 34, in the above structure, the first seal portion 2 and the second seal portion 5 are configured to avoid the smoke channel 34 from communicating with the air passage B. That is, the first seal portion 2 covers the upper surface of the transition portion 3 except for the smoke passage 34 and is in contact with the first through hole 31 and the air outlet hole 12, and the second seal portion 5 covers the lower surface of the transition portion 3 except for the smoke passage 34. In this embodiment, the first sealing portion 2 and the surface of the housing 1 contacting each other, and the second sealing portion 5 and the surface of the transition portion 3 contacting each other, both have annular protrusions, and these protrusions enable the first sealing portion 2 and the second sealing portion 5 to have a better sealing effect, and at the same time, provide a certain friction force, so that the internal structure is more stable.

Fig. 10 is a front sectional view of the transition portion of the atomizing device according to the embodiment of the present invention, which is combined with the first sealing portion. As shown in fig. 10, during the use process, as the smoke in the oil storage chamber 11 is continuously consumed, the negative pressure in the oil storage chamber 11 will be continuously increased, so as to avoid the situation of unbalanced air pressure, so that a pressure relief passage a is formed between the first sealing part 2 and the transition part 3.

The opposite surface of the first sealing part 2 and the transition part 3 is provided with a pressure relief groove 21 extending along the height direction of the first sealing part 2, the opposite surface of the transition part 3 and the first sealing part 2 is provided with a pressure relief hole 33 extending along the thickness direction of the transition part 3, wherein the pressure relief hole 33 corresponds to the position of the pressure relief groove 21, and the pressure relief groove 21 and the pressure relief hole 33 jointly form a pressure relief channel A. That is, the pressure release hole 33 is provided inside the soot channel 34 to communicate with the soot channel 34, and the pressure release groove 21 communicates with the air passage B, so that the soot channel 34 can exchange air with the external environment, thereby adjusting the air pressure in the oil storage chamber 11. Since the sizes of the pressure release holes 33 and the pressure release grooves 21 are very small, the smoke oil cannot pass through the pressure release passage A formed by the pressure release holes 33 and the pressure release grooves 21 according to certain viscosity of the smoke oil, and thus the smoke oil can be prevented from leaking under the condition of ensuring air circulation. In the present embodiment, the relief groove 21 extends only in the height direction of the first seal portion 2, and alternatively, it may extend to the top surface of the first seal portion 2 to communicate with the second through hole 22.

To sum up, the utility model discloses atomizing device can regard as the product to use alone, also can be applied to in needs such as electron cigarette use the tobacco tar atomizing product, use as the product component.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
