Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to a liquid inlet tube and an electronic cigarette. Background Technology

[0002] Existing e-cigarettes generally consist of three parts: the device, the atomizing component, and the cartridge. A charger is also an accessory. The working principle of an e-cigarette is to control the amount of vapor output and its operating status through a chip and airflow sensor. The e-liquid is atomized through a heating wire, turning a solution containing nicotine and flavoring into microparticles, which are then absorbed through the lungs while being exhaled as vapor.

[0003] Existing e-liquid is generally placed in a cartridge with a reservoir and guided to the atomizing component through an inlet tube. However, the end of the inlet tube usually comes into contact with the reservoir, which can cause localized drying of the reservoir after prolonged use, making it impossible to extract the e-liquid. Therefore, there is an urgent need to develop an inlet tube and e-cigarette to meet the needs of practical use. Utility Model Content

[0004] The purpose of this invention is to provide an inlet tube and an electronic cigarette to solve the above-mentioned defects.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A liquid inlet pipe includes a pipe body and a guide pipe. The pipe body is a columnar hollow structure, and the guide pipe is a spiral structure surrounding the outer wall of the pipe body. The guide pipe is also hollow, and its outer wall has several hollow structures. A vapor evaporation structure is provided between the pipe body and the guide pipe, and the pipe body and the guide pipe are connected through the vapor evaporation structure.

[0007] As a further embodiment of the above description, the e-liquid evaporation structure consists of a ceramic tube and a heating wire. The tube body has a horizontally opened insertion hole in the middle. Both ends of the ceramic tube extend through the insertion hole to the outside of the tube body and connect with the middle of the guide tube. The heating wire is located in the middle of the ceramic tube.

[0008] As a further embodiment of the above description, the heating wire is spirally fitted around the middle of the ceramic tube, and both ends of the heating wire extend from the inside of the tube body to one end.

[0009] An electronic cigarette includes a shell, an energy storage component, and an e-liquid assembly. The e-liquid assembly includes the aforementioned inlet tube, and also includes a shell and an oil-retaining cotton. The shell has a cylindrical hollow structure, and the inlet tube is coaxially disposed inside the shell. The oil-retaining cotton fills the inside of the shell and covers the outside of the inlet tube.

[0010] As a further embodiment, the shell is provided with a cover at both ends. The end face of the cover near the liquid inlet pipe is provided with a protruding post. The protruding post has a hollow structure and the end of the protruding post can extend to the end of the pipe body for insertion and fixation.

[0011] As a further embodiment of the above description, the energy storage component is disposed inside the housing, and the energy storage component is used to provide electrical energy to the heating wire.

[0012] As a further embodiment of the above description, the outer shell is provided with a base and a mouthpiece at both ends, the e-liquid assembly is located at the end of the outer shell near the mouthpiece, and the mouthpiece and the e-liquid assembly are connected. The energy storage component is located at the end of the outer shell near the base.

[0013] The beneficial effects of this utility model are as follows:

[0014] The present application discloses an inlet tube and an electronic cigarette. A guide tube with a hollow interior and a hollow outer wall surrounds the outside of the tube body. The guide tube is connected to the inside of the tube body through an e-liquid evaporation structure, so that the e-liquid can be evenly drawn into the oil storage cotton through the guide tube. This effectively improves the situation where the oil storage cotton dries out in some areas and cannot draw out the e-liquid. Attached Figure Description

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1 and 6 The specific implementation of the liquid inlet pipe 1 includes a pipe body 11 and a guide pipe 12. The pipe body 11 has a cylindrical hollow structure, and the guide pipe 12 has a spiral structure that surrounds the outer wall of the pipe body 11. The guide pipe 12 has a hollow structure, and its outer wall has several hollow structures. A vapor evaporation structure is provided between the pipe body 11 and the guide pipe 12, and the pipe body 11 and the guide pipe 12 are connected through the vapor evaporation structure. The guide pipe 12, which is hollow inside and has a hollow outer wall, surrounds the outside of the pipe body 11, and the vapor evaporation structure connects the guide pipe 12 to the inside of the pipe body 11. This allows the e-liquid to be evenly drawn into the oil-collecting cotton 6 through the guide pipe 12, effectively improving the situation where the oil-collecting cotton 6 becomes dry and cannot collect e-liquid.

[0024] Specific examples Figure 6 As shown, the e-liquid evaporation structure consists of a ceramic tube 13 and a heating wire 14. The tube body 11 has a horizontally opened insertion hole 111 in the middle. The two ends of the ceramic tube 13 extend through the insertion hole 111 to the outside of the tube body 11 and connect with the middle of the guide tube 12. The heating wire 14 is located in the middle of the ceramic tube 13. The middle of the heating wire 14 is spirally sleeved in the middle of the ceramic tube 13, and the two ends of the heating wire 14 extend from the inside of the tube body 11 to one end.

[0025] An electronic cigarette, such as Figure 2-6 As shown, the device includes a housing 2, an energy storage component 3, and an e-liquid assembly 5. The e-liquid assembly 5 includes the aforementioned inlet pipe 1, a housing 51, and an oil-retaining cotton 6. The housing 51 has a cylindrical hollow structure, and the inlet pipe 1 is coaxially disposed inside the housing 51. The oil-retaining cotton 6 fills the inside of the housing 51 and covers the outside of the inlet pipe 1. The energy storage component 3 is disposed inside the housing 2 and is used to provide electrical energy to the heating wire 14. The housing 2 has a base 4 and a mouthpiece 8 at each end. The e-liquid assembly 5 is disposed at the end of the housing 2 near the mouthpiece 8, and the mouthpiece 8 and the e-liquid assembly 5 are connected. The energy storage component 3 is disposed at the end of the housing 2 near the base 4.

[0026] Specific examples Figure 4As shown, both ends of the housing 51 are provided with a cover 52. The end face of the cover 52 near the liquid inlet pipe 1 is provided with a protruding post 521. The protruding post 521 is a hollow structure, and the end of the protruding post 521 can extend to the end of the pipe body 11 for insertion and fixation.

[0027] The working process of an electronic cigarette: The user inhales into the e-liquid assembly 5 through the mouthpiece 8. The e-liquid in the oil storage cotton 6 inside the shell 51 can be evenly guided through the guide tube 12 surrounding the oil storage cotton 6. The e-liquid can be guided to the ceramic tube 13 in the middle through the guide tube 12. The heating wire 14 surrounding the outside of the ceramic tube 13 can receive the signal of airflow change and start heating. The e-liquid in the middle of the ceramic tube 13 can be vaporized and atomized by the heating wire 14, and then drawn out from the protrusion 521 and the mouthpiece 8 along the hollow tube body 11.
