The elastic oil injection member is recessed toward the length direction to form a clearance groove, and the clearance groove has a notch, a groove bottom wall opposite to the notch, and a groove side wall connected to the groove bottom wall.

[0011] The clearance groove is communicated with the oil guide hole to form the oil injection channel.

[0012] In an embodiment of the present application, the oil guide hole extends from the side surface wall of the elastic oil injection member to the bottom wall of the clearance groove along the width direction.

[0013] In an embodiment of the present application, the extension length of the oil guide hole at the bottom wall of the make way groove is defined as S, the width of the bottom wall of the make way groove is defined as W, and S<W.

[0014] In one embodiment of the present application, the elastic oil injection piece is also provided with an exhaust hole, which is arranged on the side surface wall of the elastic oil injection piece and can be covered by the hole wall of the mounting hole, and can be connected with the oil storage tank when the elastic oil injection piece is deformed.

[0015] In one embodiment of the present application, the exhaust hole is on the side surface wall of the elastic oil injection member, extending from the notch of the clearance groove along the length direction;

[0016] And / or, the oil guide hole and the exhaust hole are arranged on two opposite sides of the elastic oil injection member;

[0017] And / or, at least a portion of the exhaust hole and the oil guide hole are located at the same horizontal position of the elastic oil injection member.

[0018] In an embodiment of the present application, the elastic oil injection member includes a connecting portion, a first limiting portion, and a second limiting portion;

[0019] At least part of the structure of the connecting portion is located in the mounting hole and can block the mounting hole. The oil injection channel is formed in the connecting portion. The connecting portion can be deformed under the driving of an external force. The oil injection channel can be connected to the oil storage tank when the connecting portion is deformed.

[0020] The first limiting portion and the second limiting portion are connected to two opposite ends of the connecting portion, and can be respectively limited and abutted against two opposite surfaces of the housing.

[0028] A housing, wherein an air outlet passage and an oil storage tank are formed in the housing, and the air outlet passage is communicated with the oil storage tank;

[0029] an atomizing assembly, at least a portion of the structure of the atomizing assembly being located in the air outlet passage; and

[0030] An elastic oil injection piece, wherein the elastic oil injection piece is connected to the shell, the elastic oil injection piece is provided with an oil injection channel, the elastic oil injection piece can be deformed under the drive of an external force, and the oil injection channel can be connected to the oil storage tank when the elastic oil injection piece is deformed.

[0031] The atomizer provided by the technical solution of the present invention includes a housing and an atomizing assembly. An oil storage bin is formed in the housing. The oil storage bin stores tobacco oil. The tobacco oil in the oil storage bin can be atomized by the atomizing assembly to generate tobacco oil vapor for the user to inhale. In order to continuously fill the oil storage bin with tobacco oil so that the atomizer can be used for a long time, the atomizer provided by the present solution also includes an elastic oil injection piece, which is provided with an oil injection channel. The elastic oil injection piece can be deformed under the drive of an external force to connect the oil storage bin with the oil injection channel.

[0032] Specifically, when there is no external force, the oil storage bin cannot be connected to the oil injection channel, so the tobacco oil in the oil storage bin cannot seep out from the oil injection channel. When oil injection is required, an external force can be applied to the elastic oil injection member to deform the elastic oil injection member, thereby connecting the oil storage bin and the oil injection channel, ensuring that tobacco oil can be injected into the oil storage bin through the oil injection channel, thereby increasing the service life of the atomizer and improving the utilization rate of the electronic cigarette.

[0033] By adopting the technical solution of the present application, oil is injected by connecting the oil injection channel and the oil storage tank through the deformation of the elastic oil injection member, rather than adopting the existing method of connecting or blocking the oil injection channel with the oil injection plug. This can protect children and prevent children from accidentally pulling out the oil injection plug out of curiosity, causing the oil to leak out. This can prevent children from coming into contact with the oil and causing dangerous situations. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Electronic cigarettes are a substitute for cigarettes. They can heat and atomize the stored oil to generate oil vapor for users to inhale, thus replacing existing cigarettes. They have the advantages of being healthy and convenient. Due to the volume limitation of electronic cigarettes, the amount of oil they can store is limited. In order to increase the service life of electronic cigarettes, it is necessary to continuously add oil to the electronic cigarette. Existing electronic cigarettes have an opening in the shell that is connected to the oil storage bin for storing oil, and are sealed with an oil filling plug. When oil needs to be added, the oil filling plug can be pulled out and the oil can be injected through the opening. However, in real life, children are prone to accidentally pull out the oil filling plug out of curiosity, causing the oil to leak out of the oil storage bin. If children come into contact with the oil, it will cause safety hazards and threaten children's health.

[0048] In order to solve the above problems, the present invention provides an atomizer 100 , which is applied to an electronic cigarette 1000 .

[0049] Reference Figures 1 to 6 In an embodiment of the present invention, the atomizer 100 includes a shell 10, an atomizer assembly 30 and an elastic oil injection piece 50. An air outlet channel 10a and an oil storage tank 10b are formed in the shell 10. The air outlet channel 10a is connected to the oil storage tank 10b. At least part of the structure of the atomizer assembly 30 is located in the air outlet channel 10a. The elastic oil injection piece 50 is connected to the shell 10. The elastic oil injection piece 50 is provided with an oil injection channel 50a. The elastic oil injection piece 50 can be deformed under the drive of an external force. The oil injection channel 50a can be connected to the oil storage tank 10b when the elastic oil injection piece 50 is deformed.

[0050] The atomizer 100 provided by the technical solution of the present invention includes a housing 10, an atomizing assembly 30 and an elastic oil injection piece 50. An oil storage bin 10b is formed in the housing 10. The elastic oil injection piece 50 is provided with an oil injection channel 50a. The elastic oil injection piece 50 can be deformed under the drive of an external force to connect the oil storage bin 10b with the oil injection channel 50a. When there is no external force, the oil storage bin 10b cannot be connected with the oil injection channel 50a, so the smoke oil in the oil storage bin 10b cannot seep out from the oil injection channel 50a. When oil injection is required, an external force can be applied to the elastic oil injection piece 50 so that the elastic oil injection piece 50 can be deformed, thereby connecting the oil storage bin 10b and the oil injection channel 50a, ensuring that smoke oil can be injected into the oil storage bin 10b through the oil injection channel 50a, so as to increase the service life of the atomizer 100 and improve the utilization rate of the electronic cigarette 1000. At the same time, by using the elastic oil filling member 50 to deform and connect the oil filling channel 50a and the oil storage tank 10b for oil filling, rather than using the oil filling plug to connect or block the oil filling channel 50a for oil filling, the effect of protecting children can be achieved, preventing children from accidentally pulling out the oil filling plug out of curiosity, causing the oil to leak, and preventing children from coming into dangerous contact with the oil.

[0051] Among them, the elastic oil injection part 50 can be a workpiece with a certain elasticity made of food-grade materials such as silicone, rubber, thermoplastic elastomer (Thermoplastic Elastomer, abbreviated as TPE), thermoplastic polyurethane elastomer rubber (Thermoplastic polyurethanes, abbreviated as TPU), etc., to ensure that the elastic oil injection part 50 can be deformed under the action of external force, thereby connecting the oil storage tank 10b and the oil injection channel 50a.

[0052] The elastic oil injection member 50 used in the present application can be a single component, so that the elastic oil injection member 50 also has the characteristics of simple structure and convenient manufacturing, which can reduce the manufacturing cost and labor cost. Of course, the elastic oil injection member 50 can also be composed of multiple parts to strengthen the stability of the elastic oil injection member 50 deformation part.

[0053] See also Figure 2 In one embodiment of the present application, the shell 10 is provided with a mounting hole 10c, and at least part of the structure of the elastic oil injection member 50 is limited and fixed in the mounting hole 10c; the elastic oil injection member 50 is provided with an oil guide hole 50b, and the oil guide hole 50b is arranged on the side surface wall of the elastic oil injection member 50, and can be covered by the hole wall of the mounting hole 10c, and can extend out of the mounting hole 10c and communicate with the oil storage tank 10b when the elastic oil injection member 50 is driven by an external force to deform.

[0054] Such a configuration can conceal at least part of the structure of the elastic oil injection member 50 in the mounting hole 10c to prevent direct contact by children. By limiting and fixing at least part of the structure of the elastic oil injection member 50 in the mounting hole 10c, the strength of the connection between the elastic oil injection member 50 and the housing 10 can be ensured, and the elastic oil injection member 50 cannot be pulled out from the mounting hole 10c by children, and the elastic oil injection member 50 cannot be separated from the housing 10, thereby achieving the role of protecting children and preventing children from contacting with smoke oil and causing health risks. When oil is not injected, the oil guide hole 50b can be covered by the hole wall of the mounting hole 10c, thereby ensuring that the oil guide hole 50b and the oil storage bin 10b cannot be connected when oil is not injected, thereby ensuring that the smoke oil cannot leak through the oil guide hole 50b, so that the oil guide hole 50b can only be generated when the elastic oil injection member 50 is deformed by external force to connect the mounting hole 10c with the oil storage bin 10b for oil injection.

[0055] In this embodiment, the oil guide hole 50b can be directly connected to the outside, as long as the oil filling end of the oil bottle can be connected to the oil guide hole 50b for oil filling. In this case, the oil filling channel 50a is formed by the oil guide hole 50b alone. It can be understood that the oil bottle is a container for holding oil. Of course, in addition to directly inserting the oil bottle into the oil filling channel 50a and pushing the elastic oil filling member 50 to deform for oil filling, other tools can also be used to deform the elastic oil filling member 50 and guide the oil to the oil guide hole 50b.

[0056] See also Figure 2 In an embodiment of the present application, the deformation direction of the elastic oil injection member 50 is defined as the length direction, and the direction perpendicular to the length direction is defined as the width direction. The elastic oil injection member 50 is recessed in the length direction to form a clearance groove 50c. The clearance groove 50c has a groove opening, a groove bottom wall opposite to the groove opening, and a groove side wall connected to the groove bottom wall; the clearance groove 50c is connected to the oil guide hole 50b to form an oil injection channel 50a.

[0057] The notch of the clearance groove 50c is connected to the outside world, so that the oil filling end of the oil bottle can be inserted into the clearance groove 50c from the notch of the clearance groove 50c. Specifically, after the oil bottle is inserted into the notch of the clearance groove 50c, the oil bottle is pushed in the length direction, so that the elastic oil filling member 50 can be deformed under the pushing action of the oil bottle, and the oil guide hole 50b can extend out of the mounting hole 10c and communicate with the oil storage bin 10b when the elastic oil filling member 50 is deformed. At this time, the oil bottle is squeezed, and the oil in the oil bottle can be injected into the oil storage bin 10b through the oil guide hole 50b, adding oil to the atomizer 100, thereby increasing the service life of the atomizer 100 and improving the utilization rate of the electronic cigarette 1000.

[0058] The clearance groove 50c can match the oil filling end of the oil filling bottle of the e-liquid bottle, so that the elastic oil filling member 50 is pushed by the e-liquid bottle more evenly, ensuring the stability of the structure when the elastic oil filling member 50 is deformed. Such a configuration can also reduce the size of the clearance groove 50c as much as possible to prevent children's fingers from inserting into the clearance groove 50c to push the elastic oil filling member 50. When the size of the clearance groove 50c is reduced, the volume of the elastic oil filling member 50 can also be relatively reduced, so that the area of ​​the elastic oil filling member 50 exposed to the outside can be further reduced, ensuring that children cannot push the elastic oil filling member 50 to deform the elastic oil filling member 50, and it is more inconvenient for children to pull the elastic oil filling member 50 out of the mounting hole 10c.

[0059] See also Figure 2 In one embodiment of the present application, the elastic oil injection member 50 is also provided with an exhaust hole 50d, which is provided on the side surface wall of the elastic oil injection member 50 and can be covered by the hole wall of the mounting hole 10c, and can be connected with the oil storage tank 10b when the elastic oil injection member 50 is deformed.

[0060] When filling oil, the oil guide hole 50b and the exhaust hole 50d arranged on the elastic oil filling member 50 can be connected with the oil storage bin 10b, and the smoke oil can be injected into the oil storage bin 10b through the oil guide hole 50b. When the smoke oil is injected, the gas in the oil storage bin 10b can be discharged to the outside from the exhaust hole 50d to balance the internal and external air pressure of the oil storage bin 10b, thereby ensuring that the smoke oil can be injected smoothly.

[0061] See also Figure 2 In one embodiment of the present application, the oil guide hole 50b and the exhaust hole 50d are arranged on opposite sides of the elastic oil filling member 50. In this way, the oil guide hole 50b and the exhaust hole 50d can be prevented from interfering with each other during oil filling. Specifically, when in use, the atomizer 100 can be tilted so that the opening of the oil guide hole 50b faces downward and the opening of the exhaust hole 50d faces upward. When the smoke oil is injected, the smoke oil flows into the bottom of the atomizer 100 along the oil guide hole 50b, the gas is squeezed to the top, and partially discharged from the exhaust hole 50d to balance the internal and external air pressures of the oil storage bin 10b. In addition, the atomizer 100 designed in this way can also inject enough smoke oil into the oil storage bin 10b during oil filling to prevent the smoke oil from leaking from the oil filling hole or the exhaust hole 50d during oil filling.

[0062] See also Figure 5In one embodiment of the present application, the oil guide hole 50b extends from the side surface wall of the elastic oil injection member 50 to the bottom wall of the give way groove 50c in the width direction. When the smoke oil bottle pushes the elastic oil injection member 50 to deform and inject smoke oil, the oil outlet of the oil injection end of the smoke oil bottle can be aligned with the portion of the oil guide hole 50b extending from the bottom wall of the give way groove 50c, so that the portion of the oil guide hole 50b extending from the bottom wall of the give way groove 50c can guide the smoke oil to the opening of the oil guide hole 50b, and inject it into the oil storage bin 10b from the opening of the oil guide hole 50b. The oil guide hole 50b set in this way can guide the smoke oil when injecting the smoke oil, ensure that the smoke oil can be guided through the oil guide hole 50b and injected into the oil storage bin 10b, and avoid the leakage of the smoke oil during the oil injection.

[0063] See also Figure 5 In one embodiment of the present application, the extension length of the oil guide hole 50b at the bottom wall of the clearance groove 50c is defined as S, and the width of the bottom wall of the clearance groove 50c is defined as W, where S<W. The oil guide hole 50b only needs to ensure that the oil bottle can be aligned with the extension portion of the oil guide hole 50b at the bottom wall of the clearance groove 50c when inserted. Setting S<W can prevent the oil from flowing away from the opening of the oil guide hole 50b when the oil bottle is injected with oil due to the excessive extension length of the oil guide hole 50b, thereby affecting the oil injection effect.

[0064] When the oil guide hole 50b and the exhaust hole 50d are arranged on opposite sides of the elastic oil injection member 50, setting S<W can also ensure that the oil guide hole 50b and the exhaust hole 50d can be separated, so as to better protect the oil guide hole 50b and the exhaust hole 50d from interfering with each other during oil injection, thereby avoiding affecting the oil injection effect.

[0065] See also Figure 4 In one embodiment of the present application, the exhaust hole 50d is on the side surface wall of the elastic oil filling member 50, extending from the notch of the clearance groove 50c along the length direction. In this way, it can be avoided that the exhaust hole 50d is covered when the oil filling end of the tobacco oil bottle is inserted into the clearance hole. It is ensured that when the elastic oil filling member 50 is deformed, the exhaust hole 50d can be connected to the oil storage bin 10b and the outside respectively, so as to ensure that the gas in the oil storage bin 10b can be discharged to the outside through the exhaust hole 50d to balance the internal and external air pressures of the oil storage bin 10b.

[0066] See also Figure 5In one embodiment of the present application, at least part of the exhaust hole 50d and the oil guide hole 50b are located at the same horizontal position of the elastic oil injection member 50. In this way, it can be ensured that when the elastic oil injection member 50 is pushed and deformed, the oil guide hole 50b and the exhaust hole 50d deform and move by the same distance under the same force, that is, under the same maximum force, the oil guide hole 50b and the exhaust hole 50d can be connected to the oil storage bin 10b at the same time, or covered by the hole wall of the mounting hole 10c at the same time, ensuring that the oil injection and exhaust can be carried out at the same time, and can avoid the leakage of smoke oil, and improve the oil injection effect.

[0067] See also Figure 3 In an embodiment of the present application, the elastic oil injection member 50 includes a connecting portion 51, a first limiting portion 53, and a second limiting portion 55. At least part of the structure of the connecting portion 51 is located in the mounting hole 10c and can block the mounting hole 10c. The oil injection channel 50a is formed in the connecting portion 51. The connecting portion 51 can be deformed under the drive of an external force. The oil injection channel 50a can be connected to the oil storage tank 10b when the connecting portion 51 is deformed. The first limiting portion 53 and the second limiting portion 55 are connected to the opposite ends of the connecting portion 51, and can be respectively limited and abutted against two opposite surfaces of the shell 10.

[0068] When configured in this way, the oil guide hole 50b and the exhaust hole 50d can both be provided with corresponding openings in the connecting portion 51, so that when the connecting portion 51 is deformed, they extend out of the mounting hole 10c and communicate with the oil storage tank 10b.

[0069] In this embodiment, the first limiting portion 53 can abut against the surface of the shell 10 located in the oil storage tank 10b, and the second limiting portion 55 can abut against the outer surface of the shell 10. The first limiting portion 53 and the second limiting portion 55 can limit and fix at least part of the structure of the connecting portion 51 in the mounting hole 10c.

[0070] Specifically, the deformed elastic oil injection piece 50 will rebound when the oil injection is completed, and the first limiting portion 53 can limit the position where the elastic oil injection piece 50 rebounds, ensuring that the elastic oil injection piece 50 will not pop out of the mounting hole 10c due to excessive rebound force. At the same time, the first limiting portion 53 can also abut against the housing 10 to limit the elastic oil injection piece 50, thereby preventing children from pulling the elastic oil injection piece 50 out of the mounting hole 10c, so as to achieve the effect of protecting children. The second limiting portion 55 can abut against the housing 10 to limit the elastic oil injection piece 50, thereby preventing the elastic oil injection piece 50 from being pushed into the oil storage bin 10b due to excessive external force when the elastic oil injection piece 50 is deformed by external force.

[0071] Reference Figure 3 In one embodiment of the present application, the connecting portion 51 is cylindrical. The cylindrical connecting portion 51 is easy to shape and has a small friction with the hole wall of the mounting hole 10c, which facilitates the elastic oil injection member 50 to deform when an external force acts.

[0072] Reference Figure 3 In one embodiment of the present application, the first limiting portion 53 is convexly provided on the outer peripheral surface of the connecting portion 51, and is formed with a first abutting surface 53b abutting against the housing 10. The second limiting portion 55 is convexly provided on the outer peripheral surface of the connecting portion 51, and is formed with a second abutting surface 55a abutting against the housing 10. In this way, the first limiting portion 53 and the second limiting portion 55 can respectively abut against two opposite surfaces of the housing 10, thereby enhancing the stability of the connection between the elastic oil injection member 50 and the housing 10, and can better limit and fix at least part of the structure of the connecting portion 51 in the mounting hole 10c.

[0073] In order to further improve the stability of the connection between the elastic oil injection member 50 and the housing 10, the first limit portion 53 can be arranged along the circumference of the connecting portion 51; the second limit portion 55 can be arranged along the circumference of the connecting portion 51. When the first limit portion 53 and the second limit portion 55 are arranged along the circumference of the connecting portion 51, the elastic oil injection member 50 can also completely cover the mounting hole 10c, which can prevent the tobacco oil in the oil storage bin 10b from leaking from the gap of the mounting hole 10c.

[0074] See also Figure 3 In one embodiment of the present application, in order to facilitate the connection of the elastic oil injection piece 50 and the shell 10 as one, a guide slope 53a facing the oil storage tank 10b can be formed on the first limiting portion 53. The guide slope 53a can guide the elastic oil injection piece 50 and the shell 10 when they are installed, so as to facilitate the elastic oil injection piece 50 to be inserted into the mounting hole 10c and fixed in the mounting hole 10c.

[0075] The present invention further provides an electronic cigarette 1000, an atomizer 100 of the electronic cigarette 1000, and the specific structure of the atomizer 100 refers to the above embodiments. Since the electronic cigarette 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0076] See also Figure 1 and Figure 2 The electronic cigarette 1000 may further include a host 700, which includes a housing 71 and a battery 73, and the battery 73 is placed in the housing 71. The atomizer assembly 30 is electrically connected to the battery 73, and the battery 73 can supply power to the atomizer assembly 30, so that the atomizer assembly 30 can atomize the smoke oil and discharge it from the air outlet channel 10a.
