Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to an electronic cigarette with an oil sealing structure. Background Art

[0002] The electronic cigarette converts the oil into mist through the heating element. The oil is loaded in the oil cup of the electronic cigarette. The oil in the oil cup penetrates into the oil-absorbing cotton in the atomization chamber. The heating element in the atomization chamber heats up and heats the oil to a suitable temperature to produce atomized matter. The atomization chamber is connected to the air inlet, air outlet and nozzle, so that the user can inhale the atomized matter through the nozzle.

[0003] In order to avoid oil leakage from e-cigarettes during the process from production to market, e-cigarettes are mostly shipped and transported upside down. The upside-down method can prevent the oil in the oil cup from contacting the oil absorbent cotton, thereby preventing the oil in the oil cup from gradually penetrating into the oil absorbent cotton under the action of gravity and avoiding oil leakage. However, during transportation, workers are prone to handling errors and put the e-cigarettes that should be upside down upright, causing the e-cigarettes to leak.

[0004] In addition, an oil-core separation structure is used to solve the problem of oil leakage during transportation. The heating element is usually divided into a heating wire and a ceramic chip. Generally, the oil-core separation structure can be used on electronic cigarettes with heating wires, but it is not suitable for disposable electronic cigarettes with ceramic chips. This is because if the ceramic chip is not soaked in tobacco oil, it is easy to become sticky, affecting its use.

[0005] Therefore, it is necessary to design an electronic cigarette with a new oil sealing structure to solve the oil leakage problem of ceramic chip disposable electronic cigarettes during transportation. Utility Model Content

[0029] The specific implementation modes of the present utility model are introduced with reference to the accompanying drawings.

[0030] refer to Figure 1 The figure is a schematic diagram of the three-dimensional structure of an electronic cigarette with an oil sealing structure. The upper part is a suction nozzle 22, and the lower part is a shell 1. The shell 1 is equipped with an oil cup 2, a bracket 3 and other structures. The suction nozzle 22 is blocked by a suction nozzle plug 4. The molded hole 11 in the middle of the shell 1 exposes a handle 61, and the handle 61 is connected to the air sealing plug 6.

[0031] refer to Figures 1 to 5An electronic cigarette with an oil sealing structure comprises a housing 1, an oil cup 2 and a bracket 3 arranged in the housing 1, the oil cavity of the oil cup 2 leads to the oil absorbing cotton 74 in the atomizing cavity 103, an air outlet passage 104 is formed between the suction nozzle 22 of the oil cup 2 and the atomizing cavity 103, an air inlet passage 102 leading to the atomizing cavity 103 is arranged in the bracket 3, a suction nozzle plug 4 for blocking the air outlet passage 104 is arranged at the suction nozzle 22 of the oil cup 2, an oil sealing plug 5 for sealing the oil cavity is arranged at the oil filling hole 21 of the oil cup 2, and the oil filling hole 21 is used to add oil into the oil cup 2. Injecting smoke oil; the bracket 3 is provided with an air sealing plug 6 between the air inlet duct 102 and the air inlet hole 101. In the sealed state, the suction nozzle plug 4, the oil sealing plug 5 and the air sealing plug 6 respectively block the suction nozzle 22, the oil filling hole 21 and the air inlet duct 102 to form an oil sealing structure of the electronic cigarette. In the unsealed state, the air sealing plug 6 moves to the side of the air inlet duct 102 under the action of external force, and the air inlet duct 102 is connected with the air inlet hole 101 to open the air inlet duct 102. The suction nozzle plug 4 is separated from the suction nozzle 22 under the action of external force to open the air outlet duct 104.

[0032] In the electronic cigarette with an oil sealing structure of the present embodiment, the air inlet hole 101, the air inlet passage 102, the atomizing chamber 103, the air outlet passage 104 and the suction nozzle 22 are interconnected, the suction nozzle plug 4 seals the position of the suction nozzle 22 by plugging and pulling, the oil sealing plug 5 seals the position of the oil filling hole 21, and the air sealing plug 6 seals the air inlet hole 101 and the air inlet passage 102 by pushing and pulling. The formed oil sealing structure can prevent the electronic cigarette from leaking oil, and is particularly suitable for disposable electronic cigarettes of the ceramic chip 71 type. At the same time, it is convenient to perform negative pressure and hot and cold shock tests on the electronic cigarette before shipment.

[0033] In order to pull the air sealing plug 6 inside the bracket 3, in this embodiment, refer to Figures 1 to 4 One end of the air sealing plug 6 is connected to a handle 61, which is exposed outside the shell 1. The handle 61 serves as a force-applying part for pulling the air sealing plug 6 to move by an external force.

[0034] It is understandable that with such a configuration, in a sealed state, the air sealing plug 6 can well block the air inlet hole 101 and the air inlet duct 102. When the customer needs to use it, it is necessary to unseal it, pull the air sealing plug 6 out a certain distance through the handle 61, so that the air inlet hole 101 is connected with the air inlet duct 102, and then pull out the suction nozzle plug 4 for normal suction use.

[0035] In order to facilitate holding the electronic cigarette, in this embodiment, refer to Figure 2 , Figure 4 and Figure 5 A breaking portion 62 which can be broken by external force is provided between the handle 61 and the air sealing plug 6 .

[0036] It is understandable that, with such a configuration, the function of the handle 61 is to unseal, and after the unsealing is completed, the handle 61 is no longer needed, and the handle 61 is separated from the air sealing plug 6 by the breaking portion 62, leaving the air sealing plug 6 in the bracket 3, and the handle 61 is no longer left on the electronic cigarette, so that the appearance of the electronic cigarette shell 1 is smooth, which is convenient for holding and using. At the same time, the separation of the handle 61 from the air sealing plug 6 can serve as a reminder that the electronic cigarette has been unsealed, so that the user can know whether the electronic cigarette has been unsealed and used.

[0037] In order to facilitate the handle 61 to be exposed from the bracket 3 and the housing 1, in this embodiment, Figures 1 to 4 A molded hole 11 is provided on the shell 1 , and the molded hole 11 is located on the outside of the gas sealing plug 6 , and the handle 61 is exposed from the molded hole 11 .

[0038] It is understandable that, in this configuration, the width of the profile hole 11 is greater than the width of the handle 61, and the handle 61 can be more conveniently exposed from the profile hole 11 to the outside of the housing 1.

[0039] In order to help the handle 61 separate from the gas sealing plug 6 during the unsealing process, in this embodiment, Figure 3 The width of the mold hole 11 is smaller than the width of the gas sealing plug 6.

[0040] It can be understood that, with such a configuration, the width of the molded hole 11 is between the width of the handle 61 and the width of the air-sealing plug 6. The handle 61 can pass through the molded hole 11, but the air-sealing plug 6 cannot pass through the molded hole 11. During the unsealing process, the handle 61 is pulled outward, and the handle 61 drives the air-sealing plug 6 to move to contact with the shell 1, and the air-sealing plug 6 cannot pass through the molded hole 11. After the pulling force is increased, the breaking portion 62 will break, and the handle 61 will be separated from the air-sealing plug 6, thereby leaving the air-sealing plug 6 in the shell 1 and the bracket 3.

[0041] In order to facilitate assembly, in this embodiment, reference Figures 2 to 5 The bracket 3 is provided with a card slot 34 , which is adapted to the handle 61 . In the sealed state, a part of the handle 61 is stuck in the card slot 34 .

[0042] It can be understood that, with such a configuration, the handle 61 is much higher than the bracket 3, and the portion of the handle 61 that is higher than the bracket 3 is stuck in the slot 34. During the process of being installed into the shell 1, the handle 61 will not interfere with the inner wall of the shell 1, ensuring that the bracket 3 can be smoothly installed in the shell 1, facilitating assembly. After being installed in the shell 1, the handle 61 is exposed at the mold hole 11.

[0043] In order to better control the opening and closing of the air inlet hole 101 and the air inlet passage 102, in this embodiment, reference Figure 4 and Figure 5The bracket 3 is provided with a control cavity 31 between the air inlet hole 101 and the air inlet duct 102, and the outer wall of the air sealing plug 6 is interference fit with the inner wall of the control cavity 31, and the control cavity 31 has a sealing section 32 and an unsealing section 33. The air inlet hole 101 is located between the sealing section 32 and the unsealing section 33, and the air inlet duct 102 is connected with the sealing section 32; in the sealed state, the air sealing plug 6 is located in the sealing section 32, and the air inlet hole 101 and the air inlet duct 102 are isolated by the air sealing plug 6 to close the air inlet duct 102; in the unsealed state, the air sealing plug 6 is located in the unsealing section 33, and the air inlet hole 101 is connected with the air inlet duct 102 through the sealing section 32 of the control cavity 31 to open the air inlet duct 102.

[0044] It needs to be further explained that the ceramic chip 71, battery 72, PCB board 73, oil cup 2, oil absorbing cotton 74, air sealing plug 6, oil sealing plug 5 and other components are assembled into an electronic cigarette semi-finished product. Before the electronic cigarette semi-finished product is loaded into the shell 1, a suction test can be carried out to test the suction resistance and the state of the heating wire. Before the suction test, the air sealing plug 6 is moved to the unsealing section 33. At this time, the air inlet hole 101, the air inlet airway 102, the atomization chamber 103, the air outlet airway 104 and the suction nozzle 22 are connected, so as to carry out a suction test. After the test is completed, the air sealing plug 6 is pushed to the sealing section 32, the air inlet airway 102 is completely sealed, and the handle 61 is inserted into the card slot 34, and then the electronic cigarette semi-finished product can be loaded into the shell 1.

[0045] It is understandable that, if the Figure 4 As shown, the air sealing plug 6 is located in the sealing section 32. At this time, the air inlet duct 102 and the air inlet hole 101 are completely isolated by the air sealing plug 6, thereby completely sealing the air inlet duct 102. In addition, the mouthpiece plug 4 and the oil sealing plug 5 seal the air outlet duct 104 and the oil filling hole 21, so that the atomization chamber 103 is not connected to the outside atmosphere, thereby ensuring that the electronic cigarette will not leak oil during transportation.

[0046] In order to prevent the end surface of the sealing plug 6 from being stuck in the air inlet passage 102, in this embodiment, Figure 4 The air sealing plug 6 is provided with a limiting head 63 at the other end opposite to the handle 61 , and the length of the limiting head 63 is greater than the width of the air inlet duct 102 .

[0047] It is understandable that, with such a configuration, since the air-sealing plug 6 and the control cavity 31 are in an interference fit, the air-sealing plug 6 has a certain elasticity and will undergo a certain deformation during the assembly process. The assembly of the air-sealing plug 6 is limited by the limit head 63, so that the end face of the air-sealing plug 6 will not be assembled into the air inlet duct 102, thereby preventing the end face of the air-sealing plug 6 from being stuck in the air inlet duct 102 due to extrusion deformation, and ensuring that the handle 61 can smoothly pull the air-sealing plug 6 from the sealing section 32 to the unsealing section 33.

[0048] The embodiment of the present application facilitates the assembly of the bracket 3 and the shell 1 by clamping the tail of the handle 61 in the clamping groove 34 of the bracket 3, and seals the position of the suction nozzle 22 through the suction nozzle plug 4, seals the position of the oil filling hole 21 through the oil sealing plug 5, and seals the position of the air inlet hole 101 and the air inlet duct 102 through the air sealing plug 6. The formed oil sealing structure can prevent the electronic cigarette from leaking oil, which is particularly suitable for disposable electronic cigarettes such as ceramic chips 71. At the same time, it is convenient to perform negative pressure suction and hot and cold shock tests on the electronic cigarette before shipment.

[0049] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
