Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and specifically to an electronic cigarette with a spring-loaded clutch-type oil core separation mechanism. Background Technology

[0002] Electronic cigarettes work by atomizing e-liquid into vapor using an atomizer coil, which is then placed inside the e-liquid reservoir to supply the vapor. Typically, e-cigarettes are filled with e-liquid and lubricated before leaving the factory so that consumers can immediately start using them. To meet these requirements, most e-cigarettes have the atomizer tube located inside the reservoir. The atomizer tube contains a hollow e-filled cotton layer that forms an atomization channel; this channel connects to the mouthpiece located at the top of the reservoir. The atomizer coil is housed within this atomization channel. The atomizer tube also has an inlet port that connects to the e-liquid reservoir's storage space. However, this structure, where the e-filled cotton layer is constantly supplied with e-liquid, is prone to leakage. Summary of the Invention

[0003] The technical problem solved by this invention is to provide an electronic cigarette with a spring-loaded clutch-type oil core separation; it can be filled with e-liquid before leaving the factory and can avoid the problem of oil leakage.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is:

[0005] The electronic cigarette includes an oil tank and an atomizing tube; a mouthpiece is located on the top of the oil tank, and the atomizing tube is correspondingly located inside the mouthpiece; an oil inlet is located near the bottom of the atomizing tube; characterized in that it also includes a base, a sealing bracket, and a sealing bracket silicone; the bottom of the atomizing tube is connected to the base, and the bottom end of the base can be exposed outside the bottom of the oil tank; a sealing bracket is located inside the oil tank outside the bottom end of the atomizing tube; a sealing bracket silicone is located above the sealing bracket; a spring is located outside the atomizing tube between the sealing bracket and the base; a snap-fit ​​connection structure is provided between the sealing bracket and the base to achieve a fixed connection between the two; when the base is not subjected to upward internal pressure, the oil inlet is located between the sealing bracket silicone and is in a blocked state; when the base is subjected to force and moves upward for a certain distance, the oil inlet is located above the sealing bracket silicone and is in a state of communication with the internal space of the oil tank; when the base continues to move upward for a certain distance, the snap-fit ​​connection structure between the sealing bracket and the base is connected, limiting the relative position of the sealing bracket and the base, so that the oil inlet remains in a state of communication with the internal space of the oil tank.

[0006] It also includes base silicone; the base silicone is provided in the atomizing tube above the base and below the oil inlet, which is a sealing structure connecting the base and the atomizing tube.

[0007] The top of the base is recessed to form a base step; the top is inserted into the atomizing tube, and the base step protrudes radially outward from the atomizing tube; the sealing bracket expands radially outward below the inner top of the atomizing tube to form a bracket step; the two ends of the spring abut against the base step and the bracket step.

[0008] The base step protrudes radially to form a male buckle of the snap-fit ​​connection structure; the bottom of the sealing bracket is correspondingly recessed to form a female buckle of the snap-fit ​​connection structure; when the male buckle and the female buckle are engaged, the base and the sealing bracket are fixedly engaged, limiting the oil inlet hole to be in a state of communication with the internal space of the oil tank.

[0009] The appropriate stroke for the base to move upward without being subjected to upward internal pressure, so that the oil inlet is in communication with the internal space of the oil tank, is 2.5cm; the total stroke for the base to achieve the snap-fit ​​connection with the sealing bracket is 4.3cm. At this time, the outer end of the base is flush with the bottom of the oil tank.

[0010] This invention utilizes the cooperation of a base, a sealing bracket, and a spring to allow the atomizing tube to occupy three different positions. Initially, when the base is not under internal pressure, the atomizing tube is in its original state, and the oil inlet is closed. After the base is subjected to force and moves upward a suitable distance, the oil inlet opens, entering the second state; at this time, e-cigarette e-liquid can be added. After e-liquid addition is completed and the external force is removed, the spring returns the atomizing tube to its original state, closing the oil inlet. This ensures that the oil inlet is closed after e-liquid addition, preventing leakage. When vaping is desired, the base can be pressed down until it is flush with the bottom of the e-liquid tank, and the male and female snap-fit ​​connections between the base and the sealing bracket secure the atomizing tube in a stable position with the oil inlet open, entering the third state; allowing continuous use of the e-cigarette. Therefore, this invention effectively achieves factory-filled e-liquid and closed oil inlet, preventing leakage. Attached Figure Description

[0016] The following embodiments are descriptions of specific implementations of the present invention. 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 invention. All equivalent transformations that can be obtained from the description of the embodiments of the present invention should be within the scope of protection of the present invention.

[0017] like Figures 1 to 4As shown, the electronic cigarette of the present invention includes an oil tank 1, an atomizing tube 2, a base 3, a sealing bracket 4, a sealing bracket silicone 5, a base silicone 6, and a spring 7. Figure 1 As shown, the oil tank 1 consists of an upper oil tank 11 and a lower oil tank 12; the upper oil tank 11 and the lower oil tank are connected by a snap-fit ​​mechanism. A nozzle 13 is provided at the top of the upper oil tank 11, and an atomizing tube 2 is correspondingly provided inside the nozzle 13 (an oil-storing cotton is provided inside the atomizing tube 4, and the hollow oil-storing cotton forms an atomizing channel; an atomizing core is provided inside the atomizing channel; the oil-storing cotton and the atomizing core are not shown in the figure); an oil inlet 21 is provided near the bottom of the atomizing tube 2.

[0018] The bottom of the atomizing tube 2 is connected to the base 3, and the bottom of the base 3 can be exposed at the bottom of the lower oil tank 12.

[0019] A sealing bracket 4 is installed inside the oil tank 1 outside the bottom end of the atomizing tube 2. The position of the sealing bracket 4 corresponds to the connection position of the upper and lower oil tanks; the axial position of the sealing bracket 4 is limited by the groove 14 formed by the protrusion 41 of the sealing bracket 4 after it is snapped together with the upper and lower oil tanks.

[0020] A sealing bracket silicone 5 is placed above the sealing bracket 4. Figure 1 In the original state shown, the silicone 5 of the sealing bracket blocks the oil inlet hole 21.

[0021] The top of the base 3 is recessed to form a base step 31; the top is inserted into the atomizing tube 2, and the base step 31 protrudes radially outward from the atomizing tube. The sealing bracket 4 expands radially outward below the top of the inner side of the atomizing tube to form a bracket step 42; the spring 7 is sleeved on the outside of the atomizing tube 2, and its two ends abut against the base step 31 and the bracket step 42.

[0022] A snap-fit ​​connection structure is provided between the sealing bracket 4 and the base 3 to achieve a fixed connection between the two. Specifically, the base step 31 protrudes radially outward to form a male snap 32 of the snap-fit ​​connection structure; the bottom of the sealing bracket 4 is correspondingly recessed to form a female snap 43 of the snap-fit ​​connection structure. When the male snap 32 and the female snap 43 are engaged, the base 3 and the sealing bracket 4 are fixedly engaged, limiting the oil inlet hole 21 to be in a state of communication with the internal space of the oil tank 1.

[0023] like Figure 2 As shown, when the base 3 is not subjected to upward internal pressure, the oil inlet 21 is located between the silicone 5 of the sealing bracket and is in a blocked state.

[0024] like Figure 3 As shown, when the base 3 is moved upward by an appropriate distance (2.5cm) under force, the oil inlet 21 is located above the silicone 5 of the sealing bracket and is in communication with the internal space of the oil tank 1; at this time, oil can be injected into the oil tank 1, and the injected e-liquid also lubricates the atomizer coil through the oil storage cotton. After the oil injection is completed, the oil injection device is removed; under the restoring force of the compressed spring 7, it returns to its original position. Figure 1The state shown is as follows: oil inlet 21 is closed.

[0025] like Figure 4 As shown, when the base 3 continues to move upwards for an appropriate distance (total stroke of 4.3cm), the snap-fit ​​connection between the sealing bracket 4 and the base 3 is achieved (male snap 32 and female snap 43 engage), limiting the relative position of the sealing bracket 4 and the base 3, ensuring that the oil inlet 21 remains in communication with the internal space of the oil tank 1. At this time, the outer end of the base 3 is flush with the bottom of the oil tank 1. In this state, it can be used for suction by the user.

[0026] In addition, a base silicone 6 is provided in the atomizing tube 2 above the base 4 and below the oil inlet 21 to seal the connection between the base 4 and the atomizing tube 2; to prevent oil leakage at the bottom of the atomizing tube.

[0027] The structure of the remaining parts of the electronic cigarette of the present invention is shown in the figure. The remaining parts are not related to the implementation of the aforementioned scheme; they will not be described in detail here.
