Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and specifically to a leak-proof structure for disposable electronic cigarettes with oil-retaining cotton. Background Technology

[0002] Electronic cigarettes are also known as e-cigarettes. Because e-cigarettes are similar in appearance to traditional cigarettes and do not contain tar, particulate matter, or other harmful components found in traditional cigarettes, some people use them to quit smoking or as a substitute for cigarettes.

[0003] Electronic cigarettes work by introducing e-liquid into a heating element and heating it to produce vapor, giving the user a sensation similar to smoking. The e-liquid is typically filled into a reservoir-like container; it then seeps into the heating element through a guide tube for atomization; and finally, it is inhaled into the user's mouth through the vapor chamber.

[0004] Current e-cigarettes use a foam reservoir to store e-liquid within the tank, which is sealed with silicone pads at the top and bottom. This existing structure prevents effective air expulsion from the tank when the last silicone pad is installed after refilling, leading to increased pressure and a tendency for e-liquid to overflow. Furthermore, significant changes in external air pressure (such as changes in altitude) can also cause pressure imbalances and lead to further overflow. Summary of the Invention

[0005] The technical problem solved by this invention is to provide a leak-proof structure for disposable electronic cigarettes with oil-retaining cotton; this can prevent oil leakage caused by changes in air pressure due to assembly, height changes, etc.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is:

[0007] The structure includes an upper silicone oil reservoir, an oil storage cotton, an oil reservoir, and a lower silicone oil reservoir. The upper and lower silicone oil reservoirs seal the oil storage cotton within the oil reservoir. A central shaft hole for accommodating the atomizer core assembly is provided in the center of the oil storage cotton. The portion of the central shaft hole that does not require e-liquid exchange with the atomizer core assembly is sealed by a fiberglass tube. Both ends of the oil storage cotton are further sealed by the inner surfaces of the upper and lower silicone oil reservoirs. The structure is characterized by forming a gas exchange channel within the sealed oil storage cotton, which regulates air pressure. This gas exchange channel allows for the regulation of air pressure inside and outside the space, achieving air pressure balance.

[0008] The inner center of the upper and lower silicone oil tanks has a centrally protruding plunger, which is inserted into both ends of the fiberglass tube. A shaft hole is provided in the center of the central plunger. The shaft hole and the fiberglass tube form an atomized gas channel.

[0009] The oil-absorbing cotton is designed with several venting grooves along the axial direction on its outer periphery; the venting grooves extend to both ends of the oil-absorbing cotton.

[0010] The inner surface of the silicone oil tank has a radial groove from the outer periphery to the center; an axial vent is provided in communication with the groove; the vent is at an appropriate distance from the central axis of the silicone oil tank; the outer surface of the silicone oil tank also has a return groove, the two ends of which are respectively connected to the outer end of the vent and the shaft hole of the central plunger.

[0011] The exhaust groove, slot, exhaust hole, and return groove form an airflow channel with the central plunger shaft hole; gas can enter and exit through this channel.

[0012] The inner surface of the silicone oil tank is provided with a radial lower silicone exhaust groove from the outer periphery to the center of the central plunger; the outer surface of the central plunger is connected to the lower silicone exhaust groove along the axial direction with a central plunger groove; the exhaust groove, the lower silicone exhaust groove, and the central plunger groove form an airflow channel with the central plunger shaft hole; gas can enter and exit through this channel.

[0013] The exhaust channels are evenly distributed in four circumferential directions;

[0014] The grooves are arranged in pairs symmetrically along the circumferential direction, and can be one or two pairs.

[0015] The lower silicone vent groove and the central plunger groove are arranged in pairs along the circumferential direction, and can be one or two pairs.

[0016] This invention incorporates exhaust structures in the silicone oil tank, the oil-retaining cotton, and the silicone oil tank itself. When an appropriate amount of e-liquid is injected into the oil-retaining cotton in the atomizing chamber, under high-altitude negative pressure or assembly pressure, the gas inside the atomizing chamber can exchange with the outside environment through the exhaust structure to achieve pressure balance. Because of the designed exhaust channels, e-liquid will not be squeezed out of the atomizing chamber during gas exchange, preventing leakage. Attached Figure Description

[0029] 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.

[0030] like Figure 1-11 As shown, the oil leakage prevention structure of the present invention includes an upper silicone oil tank 1, an oil storage cotton 2, an oil tank 3, and a lower silicone oil tank 4; the upper silicone oil tank 1 and the lower silicone oil tank 4 seal the oil storage cotton 2 inside the oil tank 3.

[0031] The oil-collecting cotton 2 has a central shaft hole 21 for accommodating the atomizing core assembly 5. In the existing structure, the central shaft hole 21, where there is no need for e-liquid exchange with the atomizing core assembly 5, is sealed by a fiberglass tube 6. The two ends of the oil-collecting cotton 2 are further sealed by the inner surfaces of the upper silicone 1 and lower silicone 4 of the oil tank. The central plungers 11 and 41 of the upper and lower silicone 1 and lower silicone 4 are inserted into both ends of the fiberglass tube 6. The central plungers 11 and 41 have shaft holes at their centers, forming a gas channel for atomization with the fiberglass tube 6. In the aforementioned existing structure, because the upper silicone 1, oil tank 3, lower silicone 4, and fiberglass tube 6 completely seal the oil-collecting cotton 2, it is prone to leakage due to pressure changes.

[0032] Therefore, a gas exchange channel for regulating gas pressure was designed in the oil storage cotton 2, the upper silica gel 1 of the oil tank, and the lower silica gel 4 of the oil tank; the channel for achieving this gas exchange is:

[0033] Several venting grooves 22 are designed along the axial direction on the outer periphery of the oil-absorbing cotton 2; the venting grooves 22 extend to both ends of the oil-absorbing cotton 2. In this application, four venting grooves 22 are evenly distributed in the circumferential direction.

[0034] The inner surface of the silicone sealant 1 on the oil tank has radial grooves 12 extending from the outer periphery to the center; vent holes 13 are provided in the axial direction and communicate with the grooves 12; the grooves 12 are arranged in pairs symmetrically along the circumferential direction, which can be one pair or two pairs; the vent holes 13 are at an appropriate distance from the central axis of the silicone sealant 1 on the oil tank. The outer surface of the silicone sealant 1 on the oil tank also has a return groove 14, the two ends of which communicate with the outer end of the vent hole 13 and the shaft hole of the central plunger 11, respectively. When the silicone sealant 1 on the oil tank is installed, the vent groove 22, groove 12, vent hole 13, and return groove 14 form an airflow channel with the shaft hole of the central plunger 11; gas can be discharged through this channel.

[0035] Furthermore, the inner surface of the lower silicone 4 in the oil tank has a radially arranged lower silicone vent groove 42 extending from the outer periphery to the center of the central plunger 41; the outer surface of the central plunger 41 is connected to the lower silicone vent groove 42 along the axial direction by a central plunger groove 43; the lower silicone vent groove 42 and the central plunger groove 43 are arranged in pairs along the circumferential direction, and can be one or two pairs. When the lower silicone 4 in the oil tank is installed, the vent groove 22, the lower silicone vent groove 42, and the central plunger groove 43 form an airflow channel with the shaft hole of the central plunger 41; gas can be discharged through this channel.

[0036] Through the gas channels between the oil storage cotton 2 and the upper silicone 1 and lower silicone 4 of the oil tank, the spatial air pressure of the oil storage cotton 2 can be effectively regulated to prevent oil leakage.
