AI Technical Summary
Existing electronic cigarettes are prone to leakage at the atomizer core due to improper tightness of the cotton wrapping and improper size of the oil inlet, resulting in poor sealing and difficulty in effectively preventing leakage.
The system employs a pressure relief channel composed of pressure relief silicone and an atomizer core support. This channel regulates the internal air pressure, reduces the pressure difference at the atomizer core's oil inlet, and prevents oil leakage.
Under high temperature and high-altitude negative pressure conditions, the pressure relief channel regulates the air pressure balance, reduces the risk of oil leakage, improves the sealing effect, and prevents oil leakage problems at the atomizing core oil inlet.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an open-oil electronic cigarette that prevents oil leakage through internal pressure relief. Background Technology
[0002] Currently, e-cigarettes typically use interference seals between silicone and plastic, or between metal and plastic; these hard seals create a sealed cavity to prevent leakage. However, the atomizer coil's inlet is sealed using a soft seal, where cotton padding is used to hold the inlet closed. The soft seal is often the weakest point, and factors like the tightness of the cotton padding and the size of the inlet significantly affect leakage. Too loose a padding leads to leakage, while too tight a padding leads to burnt coils; an inlet that's too large leads to leakage, and an inlet that's too small leads to burnt coils. Therefore, atomizer coil leakage is one of the most difficult problems to solve in the industry. Utility Model Content
[0003] The technical problem solved by this utility model is to provide an open-oil electronic cigarette that prevents oil leakage through internal pressure relief; and to solve the problem of oil leakage of the atomizing core by using pressure relief silicone and pressure relief channels.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:
[0005] The electronic cigarette includes an oil tank, an atomizing tube, an atomizing core, oil tank sealing silicone, and an atomizing core support. An atomizing channel is formed in the center of the oil tank, and the top of the oil tank is integrated with the atomizing channel to form a mouthpiece. The bottom of the oil tank is sealed with oil tank sealing silicone. An atomizing tube is connected below the atomizing channel, with an oil inlet and an atomizing core inside. The atomizing core support is placed at the bottom of the atomizing tube. It also includes pressure-relieving silicone, which is fitted onto the atomizing tube and located inside the atomizing core support. The pressure-relieving silicone has a thin-film deformable portion. A deformable space is formed between the pressure-relieving silicone and the atomizing core support, and the atomizing core support has a pressure-relieving channel communicating with the outside and the deformable space.
[0006] The pressure relief silicone has a disc-shaped upper part; a tubular part is formed downward from the center; the tubular part is sleeved with the atomizing tube; the oil inlet of the atomizing tube is set at a position corresponding to the axial direction of the disc-shaped part, and the oil inlet is formed by the oil tank sealing silicone, the upper part of the disc-shaped part, and the oil inlet to form an oil inlet channel from the inside of the oil tank to the atomizing core.
[0007] The disc-shaped portion of the pressure-relieving silicone forms an oil storage space; the sidewalls and bottom of the disc-shaped portion are thin-film deformable portions.
[0008] The pressure relief channel of the atomizing core support is an axially arranged vent hole; two vent holes are arranged in the circumferential direction.
[0009] A base is provided below the atomizing core support; a magnet receiving hole is provided on the base corresponding to the vent hole and communicating with the vent hole; a magnet is provided in the magnet receiving hole and magnetically connected to the rest of the electronic cigarette; a gap is left between the magnet and the magnet receiving hole.
[0010] The inner wall of the magnet receiving hole protrudes from the bone; the magnet receiving hole is press-fitted with the magnet through the bone, and a gap is formed between the outer wall of the magnet and the inner wall of the magnet receiving hole.
[0011] This invention improves upon the conventional "blocking" method used in electronic cigarettes by reducing internal "pressure" to decrease the pressure difference at the atomizer core's inlet during high-temperature transportation and high-altitude negative pressure. This invention utilizes a deformation-controlled space between the pressure-relieving silicone and the plastic component (atomizer core support). At high temperatures, the internal expansion pressure increases; therefore, a pressure-relieving channel directly connects to the outside, reducing the pressure of the internal oil on the atomizer core's inlet and lowering the risk of leakage. Under high-altitude negative pressure, insufficient sealing of the mouthpiece or bottom silicone plug can cause air to be slowly drawn out of the main airflow channel, drawing oil from the atomizer core's inlet and causing leakage. In this situation, the pressure-relieving channel of this invention is simultaneously under negative pressure, causing the pressure-relieving silicone to deform, reducing the pressure difference at the atomizer core's inlet and further lowering the risk of leakage.

[0020] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.
[0021] like Figure 1-7 As shown, the electronic cigarette of this utility model includes an oil tank 1, an atomizing tube 2, an atomizing core 3, an oil tank sealing silicone 4, an atomizing core support 5, and a pressure relief silicone 6. An atomizing channel 11 is formed in the center of the oil tank 1, and the top of the oil tank is integrated with the atomizing channel to form a mouthpiece 12; the bottom of the oil tank 1 is sealed with oil tank sealing silicone 4; the atomizing tube 2 is connected below the atomizing channel 11, and an oil inlet 21 is opened on the atomizing tube 2, and the atomizing core 3 is installed inside; the atomizing core support 5 is supported at the bottom end of the atomizing tube 2.
[0022] The upper part of the pressure-relieving silicone 6 is a disc-shaped portion 61; a tubular portion 62 is formed downward from the center of the disc-shaped portion 61; the tubular portion 62 is sleeved with the atomizing tube 2; the oil inlet 21 of the atomizing tube 2 is set at a position corresponding to the axial direction of the disc-shaped portion 61, and the oil inlet 21 forms an oil inlet channel from the inside of the oil tank 1 to the atomizing core 3. The disc-shaped portion 61 forms an oil storage space; the side walls and bottom of the disc-shaped portion 61 are thin-film deformable portions 63.
[0023] The pressure-relieving silicone 6 is located inside the atomizer core support 5, and a deformation space 7 is formed between the deformable part 63 of the pressure-relieving silicone 6 and the atomizer core support 5. The atomizer core support 5 is provided with vent holes 51 that communicate with the outside and the deformation space 7; a pressure relief channel is formed through the vent holes 51. To ensure even air release, two vent holes 51 are arranged in the circumferential direction.
[0024] A base 8 is provided below the atomizing core support 5; a magnet receiving hole 81 is provided on the base 8 corresponding to the vent hole 51 and communicating with the vent hole 51; a bone position 82 protrudes from the inner wall of the magnet receiving hole 81; the magnet receiving hole 81 is press-fitted with the magnet 9 through the bone position 82, and a gap is formed between the outer wall of the magnet 9 and the inner wall of the magnet receiving hole 81.
[0025] At high temperatures, the internal expansion pressure increases, causing the deformable portion 63 of the venting silicone 6 to expand and deform towards the atomizer core support 5, compressing the deformation space 7. Air within the deformation space 7 can be expelled to the outside through the vent 51 and the magnet receiving hole 81, thus regulating the internal air pressure balance. At high atmospheric negative pressure, the deformable portion 63 contracts inward, increasing the deformation space 7. External air can then fill the deformation space 7 through the magnet receiving hole 81 and the vent 51, regulating the air pressure balance. Therefore, regardless of air pressure changes, the air pressure on both sides of the oil inlet 51 of the atomizer core 5 can remain balanced, preventing oil leakage.
[0026] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. Their connection and cooperation are unrelated to the implementation of the aforementioned scheme; they will not be described in detail here.
