Referring to fig. 1, in the related art, an oil bin 101, an oil storage cotton 5 positioned in the oil bin 101, a smoke delivery channel 201, an atomization core 3 for atomizing the tobacco oil on the oil storage cotton 5 into smoke and delivering the smoke into the smoke delivery channel 201, and a suction nozzle 7 installed at the outlet of the smoke delivery channel 201 are provided in the electronic cigarette.

In general, tobacco tar is stored in the oil storage cotton 5, and when a user uses the electronic cigarette, the atomizing core 3 atomizes the tobacco tar on the oil storage cotton 5, and then sends the smoke into the smoke delivery channel 201, so that the user can suck at the suction nozzle 7.

In order to prevent the excessive pressure in the oil sump 101 caused by the high temperature environment, a pressure release channel 8 is usually provided between the oil sump 101 and the smoke delivery channel 201 to achieve the pressure release effect.

When the opening of the pressure release channel 8 is too small, the interior of the oil bin 101 is heated and expanded, and the pressure forces tobacco tar in the oil storage cotton 5 to flow outwards, namely, the tobacco tar flows out of the atomization core 3 to cause oil leakage, and after the opening of the pressure release channel 8 is enlarged, smoke sucked by a user can escape from the pressure release channel 8, so that fragrance loss exists.

The utility model provides an electronic atomizer which can be used as an electronic cigarette and the like, and can effectively solve the problems that a pressure release channel in the related technology cannot balance fragrance loss and pressure release cannot be performed timely, and oil leaks.

Referring to fig. 2, in the present embodiment, the electronic atomizer includes a housing 1, a smoke feeding tube 2, an atomizing core 3, a ventilation block 4, an oil storage cotton 5, an oil absorbing cotton 6, and a suction nozzle 7.

The inside of shell 1 is equipped with oil storehouse 101, and oil storage cotton 5 is located oil storehouse 101 for the tobacco tar is stored. A suction nozzle 7 is mounted on top of the housing 1 and provided with a suction hole 701.

The smoke feeding pipe 2 is positioned in the oil bin 101 and is provided with a smoke feeding channel 201. For example, the smoke feeding pipe 2 may be a glass fiber pipe or the like. The atomizing core 3 is installed at the bottom of the smoke delivery pipe 2, and is used for atomizing the tobacco tar in the oil bin 101 and delivering the atomized tobacco tar into the smoke delivery channel 201.

The ventilation block 4 is located in the oil bin 101 and between the suction nozzle 7 and the smoke delivery pipe 2, and an insertion pipe groove 401 for inserting the upper end of the smoke delivery pipe 2 is formed in the bottom of the ventilation block 4.

The middle position of the bottom of the insertion tube groove 401 is provided with a smoke delivery hole 402, the oil absorbing cotton 6 is positioned at the top of the air exchanging block 4, and an oil absorbing hole 601 which is communicated with the suction hole 701 and the smoke delivery hole 402 is formed.

Referring to fig. 3 and 4, a liquid locking boss 403 protruding downward is disposed at the hole opening at the lower end of the smoke delivery hole 402, a liquid locking groove 404 is formed between the liquid locking boss 403 and the wall of the insertion tube 401, and a pressure release channel 8 communicating the smoke delivery channel 201 and the smoke delivery hole 402 is left between the smoke delivery tube 2 and the ventilation block 4.

Further, a clearance space is reserved between the groove wall of the insertion groove 401 and the outer wall of the smoke delivery pipe 2.

In the electronic atomizer provided in this embodiment, in general, tobacco tar is stored in the oil storage cotton 5, and when the electronic cigarette is required to be inhaled, the atomization core 3 atomizes the tobacco tar in the oil storage cotton 5 and then sends the atomized tobacco tar into the smoke delivery channel 201, and then sends the smoke into the mouth of a user through the smoke delivery hole 402, the oil suction hole 601 and the suction hole 701 in sequence.

In other related technologies, the oil storage cotton 5 directly wraps the pressure release channel 8, and the pressure in the oil bin 101 is released to the pressure release channel 8 through the oil storage cotton 5, so that the release process is slow, and therefore, the problem of rapid expansion and pressure release caused by high temperature is to be solved, and the mode can only increase the size of the pressure release channel 8, but the problem of insufficient fragrance is brought.

However, in this embodiment, during the high temperature test, the temperature inside the electronic atomizer increases, the air pressure in the oil bin 101 increases, and the air to be decompressed enters the gap space through the notch at the lower end of the cannula slot 401, so that decompression is realized through the decompression channel 8, and in this process, the decompression air comes from the upper space of the oil storage cotton 5, and even if the oil storage cotton 5 expands, the decompression channel 8 is not blocked, so that the size of the decompression channel 8 can be reduced.

In some embodiments, the gap size of the pressure release channel 8 is between 0.1mm and 0.3mm, preferably 0.2mm, and the pressure release channel gap of 0.2mm is a smaller size value, so that the smoke escaping from the opening is reduced, the fragrance is reserved, and the smooth ventilation is realized, and the air pressure is kept stable.

It will be appreciated that in some cases, the gas-liquid mixture escaping from the pressure relief channel 8 may condense by contacting the walls of the cannula 401 and/or the walls of the smoke delivery tube 2, and that condensation may also form smoke and oil that falls back into the sump 101.

In some cases, there may be a problem that part of the tobacco tar oozes out of the oil storage cotton 5 due to the electronic atomizer or the negative pressure, but the oozed tobacco tar enters the liquid locking groove 404 at this time, and the tobacco tar cannot enter the pressure release channel 8 due to the liquid locking boss 403.

In some embodiments, the walls of the cannula slot 401 are provided with longitudinal grooves 405. The longitudinal grooves 405 can increase the surface area of the cannula groove 401, so that the width of the tobacco tar attached to the longitudinal grooves 405 of the cannula groove 401 is smaller than 0.8mm, preferably 0.4mm, 0.5mm and 0.6mm, and although the surface tension of different tobacco tar is different, the oil drops in the longitudinal grooves 405 are difficult to flow in the three widths, thereby realizing the function of locking the oil, and even if the electronic atomizer shakes, the oil drops only move in the longitudinal grooves 405 and do not flow to the pressure release channel 8.

Therefore, the electronic atomizer provided by the utility model has the advantages that the ventilation block 4 is arranged to well balance the timely pressure release problem under the condition of reducing the aroma loss as much as possible, and meanwhile, the smoke feeding pipe 2 is inserted into the pipe inserting groove 401, so that the electronic atomizer is more stable after assembly.

Further, the diameter of the notch of the insertion tube groove is larger than the diameter of the groove bottom, in one embodiment, the diameter of the notch of the insertion tube groove 401 is gradually increased towards the direction away from the groove bottom to form a flare structure 4011, so that gas in the oil sump 101 can smoothly enter the insertion tube groove 401, a good pressure release effect is achieved, and meanwhile assembly and assembly between components are facilitated.

In this embodiment, the ventilation block 4 is a silica gel block or a rubber block, which is not easy to be heated up, and has a good condensation effect.

In summary, the electronic atomizer provided in this embodiment has the following advantages:

1. The air in the upper part of the oil bin can flow to the pressure release channel from the cannula groove and the outer wall of the air delivery pipe during pressure release, so that the pressure release and ventilation are smoother, and the opening gap of the pressure release channel can be adjusted as required to avoid losing fragrance.

2. The gap space and the liquid locking groove can store a small amount of tobacco tar, and provide a tobacco tar storage function when the electronic cigarette is inverted or the small amount of tobacco tar caused in the qualification test process seeps out of the oil storage cotton.

The gap between the pressure release channels with the thickness of 3.0.1mm-0.3mm is a smaller size value, so that the smoke escaping from the opening is reduced, fragrance is reserved, and meanwhile, smooth ventilation is realized, and the air pressure is kept stable.

4. The width of the longitudinal groove smaller than 0.8mm has the oil drop latching capability, and when oil liquid seeps out of the oil storage cotton to form oil drops, the oil drops are difficult to flow in a groove channel smaller than 0.8mm due to surface tension no matter transverse or inverted electronic cigarettes, so that oil locking is realized.

5. The block of taking a breath is towards one side of oil storage cotton is equipped with the top and supports the boss, and relative oil storage cotton is supporting the boss periphery and is having the head space, therefore when the high temperature test, oil storage cotton volume probably expands more than 3%, and this head space can provide expansion space for oil storage cotton, reduces the impact to the block of taking a breath, has reduced the influence to the pressure release passageway simultaneously.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.

The above list of detailed descriptions is only specific to practical embodiments of the present utility model, and they are not intended to limit the scope of the present utility model, and all equivalent embodiments or modifications that do not depart from the spirit of the present utility model should be included in the scope of the present utility model.
