Description

Technical Field

[0001] The invention belongs to the field of electronic atomizing cigarettes, and in particular relates to an atomizer which can prevent secondary oil injection through an oil injection hole. Background Art

[0002] Electronic cigarettes, also known as electronic atomizer cigarettes, can produce smoke like cigarettes for consumers to inhale. The atomizer includes an oil storage tank, an aerosol channel and an atomizer core. The oil storage tank is filled with smoke oil. The atomizer core includes an oil guide body and a heating wire. The oil guide body absorbs the smoke oil in the oil storage tank through the oil inlet hole, and the smoke oil in the oil storage tank continuously flows into the oil guide body through the oil inlet hole. The heating wire heats and atomizes the smoke oil that has been adsorbed in the oil guide body, and the atomized aerosol flows along the aerosol channel to the air outlet for people to inhale.

[0003] The supply of smoke oil in this electronic cigarette adopts the method of continuous absorption of smoke oil by the oil guide body. Although the oil guide body itself has the ability to absorb and guide the smoke oil, this ability to absorb the smoke oil is limited. When not in use, the oil guide body will also absorb the smoke oil. Due to the influence of gravity, the smoke oil absorbed by the oil guide body will seep downward, or drip downward, causing the smoke oil to flow out along the air inlet. This is the common smoke oil leakage phenomenon. Therefore, in terms of design, the tightness of the oil guide body is reworked to prevent oil leakage. If the oil guide body is made too tight, the ability of the oil guide body to absorb the oil will decrease, resulting in insufficient oil supply during the subsequent heating process, resulting in dry burning. If the oil guide body is made too loose, oil leakage will occur. Therefore, an intermediate value is found on the oil guide body. Although this intermediate value can solve the problems of insufficient oil supply and oil leakage, the problems that follow are again. If the smoke cartridge is made in area A, the air pressure of the oil in the smoke cartridge is equal to the air pressure outside when it is made in area A. At this time, the oil guide cotton can just hold the oil and the oil will not leak out. If the smoke cartridge is sent to area B, the air pressure in area B is lower than that in area A. At this time, the oil guide body cannot hold the oil, which will inevitably lead to the leakage of the oil in the smoke cartridge. In addition, during the transportation process, if the oil is subjected to continuous shock from the outside world, the oil is bound to leak out. This is inevitable, especially in air transportation. Since the air pressure in the aircraft transport cabin is different from that in the outside world, the oil in the smoke cartridge also leaks out during transportation.

[0004] In order to solve the above problems, the present invention is proposed. Summary of the invention

[0005] The first aspect of the present invention provides an oil leakage-proof aerosol atomizer, comprising:

[0006] The housing 1 has an oil filling hole 12 at the downstream of the housing 1, which is communicated with an oil storage tank 13 inside the housing 1; the downstream of the housing 1 has a smoke passage 11 inside, and the side wall of the housing 1 has a first clamping hole 14 and a second clamping hole 15, and the second clamping hole 15 is located downstream of the first clamping hole 14;

[0007] The first tube body 3 is located inside the housing 1 and has an oil inlet hole 31 on its side wall, and has an atomizing core 32 and oil guide cotton 33 inside.

[0008] A rubber stopper 4 having a central hole 41, wherein the central hole 41 allows the first tube 3 to pass through;

[0009] A base 2 having an air inlet 21, and a clamping portion 22;

[0010] The base 2 and the first tube body 3 have a first position and a second position respectively. In the first position, the clamping portion 22 matches the first clamping hole 14, and the oil inlet hole 31 is located at the central hole 41 of the rubber plug 4 and is sealed by the rubber plug 4; the base 2 pushes the first tube body 3 to move downstream to the second position. In the second position, the clamping portion 22 matches the second clamping hole 15, and the oil inlet hole 31 is exposed in the oil storage bin 13. The oil-guiding cotton 33 absorbs the smoke oil from the oil storage bin 13 through the oil inlet hole 31, and the atomizing core 32 heats the smoke oil in the oil-guiding cotton 33 to generate an aerosol that can be inhaled.

[0011] Preferably, the oil filling hole 12 is sealed by a sealing cover 7 .

[0012] Preferably, the atomizer further comprises a connecting member 5 , and the connecting member 5 connects the smoke channel 11 and the first tube body 3 .

[0013] Preferably, the connecting member 5 includes a first groove 51 and a second groove 52, the first groove 51 has a first sealing ring 53, the second groove 52 has a second sealing ring 54, the connecting member 5 functions to connect the smoke channel 11 and the first tube body 3, and the first sealing ring 53 and the second sealing ring 54 functions to seal the connection between the smoke channel 11, the first tube body 3 and the connecting member 5.

[0014] Preferably, the first tube body 3 is sleeved on the outside of the connecting member 5 , and when the first tube body 3 moves from the first position to the second position, the first tube body 3 moves on the outer wall of the connecting member 5 .

[0015] Preferably, the side wall of the shell 1 has a holding area inside, and the rubber plug 4 has a fixing plate 6 downstream. The base 2, the rubber plug 4 and the fixing plate 6 are located in the holding area. The fixing plate 6 is made of a rigid material. The purpose is that when the base 1 pushes the first tube body 3 to move from the first position to the second position, the rubber plug 4 is soft and prone to deformation, so that the originally fixed rubber plug 4 also moves downstream with the first tube body 3, causing the oil inlet hole 31 on the first tube body 3 to be unable to be exposed to the oil storage bin 13, further causing the oil guide cotton 33 to be unable to absorb smoke oil from the oil storage bin 13, and the atomizer cannot work normally.

[0016] Preferably, a first clamping hole 14 and a second clamping hole 15 are provided on the side wall of the housing 1 , and the second clamping hole 15 is located downstream of the first clamping hole 14 .

[0017] Preferably, the base 2 has a clamping portion 22 ; when the base 2 is in the first position, the clamping portion 22 matches the first clamping hole 14 , and when the base 2 is in the second position, the clamping portion 22 matches the second clamping hole 15 .

[0018] Preferably, the outer side of the rubber stopper 4 has a convex rib 42 to increase the friction between the rubber stopper 4 and the housing 1 to prevent the rubber stopper 4 from moving downstream along with the first tube body 3 .

[0019] A second aspect of the present invention provides an electronic cigarette comprising the atomizer, wherein the electronic cigarette further comprises a power supply, a control circuit, an air inlet and other components to ensure the normal operation of the electronic cigarette. The atomizer portion is placed inside the shell and is adapted to the control circuit, power supply and the like to heat the e-liquid to produce an inhalable aerosol.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the atomizer of the present invention is being transported, the base 2 and the first tube body 3 are both in the first position, at which time the oil inlet hole 31 is sealed by the rubber plug 3, and the oil-guiding cotton 33 in the first tube body 3 cannot absorb the oil from the oil storage bin 13 through the oil inlet hole 31; when the atomizer is used for the first time, the base 2 pushes the first tube body 3 to move downstream to the second position. In the second position, the oil inlet hole 31 is exposed to the oil storage bin 13, and the oil-guiding cotton 33 can absorb the oil from the oil storage bin 13. The atomizer core 32 heats the oil in the oil-guiding cotton 33 to generate an aerosol that can be inhaled, thereby avoiding the problem of oil leakage in the oil-guiding cotton 33 due to changes in external air pressure or continuous bumps during transportation after the oil-guiding cotton 33 absorbs the oil during transportation of the atomizer.

[0022] 2. The side wall of the housing 1 of the present invention is provided with a first clamping hole 14 and a second clamping hole 15, wherein the second clamping hole 15 is located downstream of the first clamping hole 14, and the base 2 is provided with a clamping portion 22; when the base 2 is in the first position, the clamping portion 22 matches the first clamping hole 14, and when the base 2 is in the second position, the clamping portion 22 matches the second clamping hole 15. The clamping portion 22 and the first clamping hole 14 and the second clamping hole 15 are all matched once, that is, this matching mode only allows the first tube 3 to move downstream to the second position through the base 2, but does not allow the base 2 to be pulled upstream to return to the first position, so this matching mode that only allows movement from the first position to the second position but does not allow movement from the second position to the first position is called a one-time matching mode, which can prevent the occurrence of situations such as artificially pulling out the base 2 and injecting unqualified smoke oil into the oil storage bin 13 again, or configuring smoke oil by oneself, etc., which also avoids the problem of poor sealing at the oil injection hole and oil leakage caused by multiple injections of oil into the oil storage bin through the oil injection hole.

[0023] 3. In a preferred embodiment of the present invention, a fixing plate 6 is provided downstream of the rubber stopper 4, and the base 2, the rubber stopper 4 and the fixing plate 6 are located at the clamping area, and the fixing plate 6 is made of a rigid material. The purpose is that when the base 1 pushes the first tube body 3 to move from the first position to the second position, the rubber stopper 4 is easily deformed due to its soft material, so that the originally fixed rubber stopper 4 also moves downstream with the first tube body 3, causing the oil inlet hole 31 on the first tube body 3 to be unable to be exposed to the oil storage bin 13, further causing the oil guide cotton 33 to be unable to absorb the smoke oil from the oil storage bin 13, and the atomizer cannot work normally.
