Specifically, the second sealing element 35 is accommodated in the accommodating space 34 and is disposed between the accommodating space 34 and the heating element 40 in a sealing manner, and partially wraps the ceramic oil guide seat 41. Therefore, the soot in the accommodating space 34 cannot flow out from the gap between the ceramic oil guide seat 41 and the accommodating space 34, but only enters the ceramic oil guide seat 41 and is guided to the heating element 42. Alternatively, the second sealing member 35 may be a sealing gel, a sealing grease, a sealing material such as a sealing silicone, or the like.

Referring to fig. 3, in the present embodiment, the base 50 is connected to the cartridge tube 10 and is sealed at the bottom of the cartridge tube 10, and optionally, the cartridge tube 10 and the base 50 may be connected by a snap connection, an adhesive connection, or a magnetic attraction connection.

Optionally, the vent holes 56 may be provided with two or more, further enhancing the flow rate of the gas within the nebulizer 1.

Referring to fig. 3 and 5, oil reservoirs 52 may be further formed on two outer sidewalls of the base 50, and the oil reservoirs 52 are connected to the atomizing space 51. In a normal condition, after the heating element 42 heats the tobacco smoke and atomizes the tobacco smoke to form smoke in the atomizing space 51, the smoke cannot completely flow out of the smoke outlet 33, and the residual smoke can enter the oil storage tank 52, and the oil storage tank 52 stores condensate (not shown) generated after the smoke condenses.

Alternatively, the magnetic member 54 may be a magnet.

In prior art, the tobacco tar is stored in oil storage chamber 11, and when the atomizer 1 of electron cigarette was in operating condition, the accommodation space 34 in the oil storage chamber 11 got into support 30 from inlet port 31, and the heating element 40 heating atomization in the accommodation space 34 produced smog to make the tobacco tar in the oil storage chamber 11 constantly reduce, the interior gas pressure of oil storage chamber 11 reduces, forms the negative pressure. At this time, the oil storage chamber 11 in the negative pressure state is difficult to enter the accommodating space 34 from the oil inlet 31, the oil supply to the oil storage chamber 11 is not smooth, and the smoke oil flowing into the heating element 40 is slowly reduced, so that the scorched smell is generated, and the user experience is seriously influenced. Referring to fig. 6, in order to solve the problem of negative pressure in the oil storage chamber 11, the bracket 30 of the atomizer 1 of the electronic cigarette of the present application is provided with a ventilation channel 32, and the ventilation channel 32 communicates the oil storage chamber 11 and the atomization space 51, so as to balance the air pressure in the oil storage chamber 11. The external air used here and below refers to the external air with respect to the oil storage chamber 11, and the external air may be the air in the ventilation channel 32, the air in the atomization space 51, or the air outside the atomizer 1 of the electronic cigarette.

Referring to fig. 3 and 6, in the present embodiment, the ventilation channel 32 includes a ventilation hole 321 and a ventilation slot 322 connected to the ventilation hole 321. The ventilating hole 321 is disposed at the top of the bracket 30 and on the same side as the oil inlet hole 31, and the ventilating hole 321 is communicated with the oil storage chamber 11.

Alternatively, the number of the venting holes 321 and the air-guiding grooves 322 may be two or more, each venting hole 321 communicates with one air-guiding groove 322 or one air-guiding groove 322 may communicate with a plurality of venting holes 321.

Optionally, the air guide groove 322 is disposed on an outer sidewall of the bracket 30 in a bent shape, and is bent at least once to increase the volume of the air guide groove 322. The air guiding groove 322 extends from at least one end of the ventilating hole 321 far away from the top of the support 30 to the bottom of the support 30, that is, the ventilating hole 321 is divided into two ends, and the air guiding groove 322 extends from at least one end of the ventilating hole far away from the top of the support 30 to one side of the bottom of the support 30 close to the atomization space 51. Of course, in other embodiments, the air guide slot 322 may not be bent, for example, the air guide slot 322 is a straight slot.

Alternatively, the air guide groove 322 may be bent in an arc shape or an angle.

The air guide groove 322 extends from one wall surface of the outer side wall of the bracket 30 to the other wall surface opposite to the other wall surface, the volume of the air guide groove 322 is further increased, the volume of the air stored in the air guide groove 322 is increased, and the two ends of the air guide groove 322 extend to the bottom of the bracket 30 to communicate with the atomization space 51.

One end of the air guide groove 322 is communicated with the air vent 322, and the other end is communicated with the atomization space 51, and is used for guiding the outside air to be guided into the oil storage cavity 11 and balancing the air pressure of the oil storage cavity 11.

As shown in fig. 7, in the present embodiment, the air guide groove 322 communicates with the atomization space 51, and the atomization space 51 is connected to the vent hole 56. The air outside the smoke and bomb tube 10 can pass through the atomizing space 51, the air guide groove 322, the vent hole 321 and the through hole 21 in sequence through the vent hole 56 and enter the oil storage cavity 11, so that the effect that the outside air can enter the oil storage cavity 11 is achieved, and the problem of negative pressure in the oil storage cavity 11 is solved.

Further, in order to prevent the smoke in the oil storage chamber 11 from flowing into the ventilation hole 321 while ventilating, a check valve member may be provided on the bracket 30. The one-way valve member is connected with the ventilation channel 32, when the one-way valve member is opened, the external air can be allowed to enter the oil storage cavity 11 through the ventilation channel 32, and when the one-way valve member is closed, the smoke oil in the oil storage cavity 11 is blocked from flowing out through the ventilation channel 32. Specifically, in this embodiment, the check valve member is a first sealing member 20 shown in fig. 6.

Referring to fig. 8, fig. 8 is a schematic structural view illustrating a closed structure of a check valve member when a support of an atomizer according to an embodiment of the present invention is connected to a first sealing member (check valve member), in the embodiment of the present invention, a portion of the first sealing member 20 covering the top of the support 30 is provided with a through hole 21 corresponding to and communicating with a ventilation hole 322, the through hole 21 communicates with an oil storage chamber 11 and a ventilation hole 321, and external air can enter the oil storage chamber 11 through the through hole 21.

Alternatively, the through hole 21 may be a semicircular hole as shown in fig. 8, or may be a circular hole, a square hole, or a hole with other shapes.

Optionally, the number of the through holes 21 is two, and two ventilation holes 321 correspondingly disposed on different sides of the top of the bracket 30 are respectively disposed, and certainly, when there are more than two ventilation holes 321, the number of the through holes 21 also corresponds to the number of the ventilation holes 321.

A ventilation cover 22 is protruded from the edge of the through hole 21, and the ventilation cover 22 is covered on the ventilation hole 322. The ventilation cover 22 is arranged in a protruding manner, which means that the ventilation cover 22 extends from the edge of the through hole 21 and protrudes outwards to form the ventilation cover 22. The area of the ventilation cover 22 is smaller than or equal to the through hole 21.

The area of the ventilation cover 22 is larger than that of the ventilation hole 321 so as to completely shield the ventilation hole 321 and prevent the smoke in the oil storage chamber 11 from entering the ventilation hole 321. Meanwhile, since the area of the ventilation cover 22 is larger than the area of the ventilation hole 321, the periphery of the ventilation cover 22 abuts against the top of the bracket 30, and the ventilation cover 22 cannot rotate around the edge of the through hole 21 in the direction approaching the ventilation hole 321. As shown in fig. 8, when the breather cover 22 receives the weight of the soot in the oil storage chamber 11, the breather cover 22 is in a balanced state by the weight of the soot and the supporting force of the bracket 30, the breather cover 22 is closed, and the check valve member is closed. At this time, the ventilation hole 321 is completely blocked by the ventilation cover 22, and the smoke in the oil storage chamber 11 cannot enter the ventilation hole 321.

As shown in fig. 9, fig. 9 is a schematic structural view of the opening of the check valve member when the bracket of the atomizer according to the embodiment of the present invention is connected to the first sealing member (check valve member), when the ventilation cover 22 is pushed by the outside air, the ventilation cover 22 can rotate around the edge of the through hole 21 in the direction approaching the oil storage chamber 11, the ventilation cover 22 is opened, and the ventilation hole 321 is communicated with the oil storage chamber 11. At this time, the external air can enter the through hole 21 and the oil storage chamber 11 from the ventilation channel 32 to solve the problem of the negative pressure of the oil storage chamber 11 and balance the air pressure of the oil storage chamber 11. Meanwhile, the negative pressure of the oil storage cavity 11 can increase the flow rate of gas, increase the thrust of the outside gas and increase the efficiency of the outside gas entering the oil storage cavity.

Therefore, when the electronic cigarette 3 of the present application is horizontally placed (the oil chamber 11 is located above the holder 30), the smoke in the oil chamber 11 does not flow into the ventilation channel 3 due to the weight of the smoke. Meanwhile, when the air pressure of the oil storage chamber 11 is normal (the air pressure of the oil storage chamber 11 is equal to the external air pressure), the oil storage chamber 11 does not need to be ventilated, and the ventilation cover 22 does not open. When the smoke is consumed in the oil storage chamber 11 to generate negative pressure, the oil storage chamber 11 needs to be ventilated, the negative pressure increases the flow rate of the external air into the oil storage chamber 11 to open the ventilation cover 22 of the ventilation channel 32, and the external air enters the oil storage chamber 11 through the ventilation channel 32 to be ventilated. The ventilation means that outside air enters the oil storage cavity 11, so that the air pressure in the oil storage cavity 11 is equal to the air pressure outside the electronic cigarette 3. Therefore, the atomizer 1 of the electronic cigarette can close the ventilation cover 22 when the ventilation is not needed, and can open the ventilation cover 22 to perform ventilation when the ventilation is needed, and the tobacco tar can not flow into the ventilation channel 3 due to the gravity of the tobacco tar, so that the effects of saving the tobacco tar and balancing the air pressure of the oil storage cavity 11 are achieved.

In other embodiments, the one-way valve member may be another venting cover (not shown) disposed on the venting channel 32, and the other venting cover is protruded from the edge of the venting hole 321, and similarly, the one-way passage of the gas can be realized to block the oil smoke. All the parts for allowing outside air to pass and blocking the smoke oil from flowing out can be one-way valve parts.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

The above description is only an example of the present application, and is not intended to limit the scope of the present application, and all equivalent structures or equivalent processes performed by the present application and the contents of the attached drawings, which are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
