Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes, and in particular to a press-operated oil bottle and an electronic cigarette. Background Technology

[0002] As people become more health-conscious and aware of the harmful effects of tobacco, e-cigarettes have emerged. E-cigarettes typically deliver e-liquid to users through an atomizer. During the e-liquid's production, harmful substances such as nicotine and tar are removed, eliminating their harmful effects. Furthermore, because e-liquids lack nicotine and tar, users' cravings gradually decrease, thus e-cigarettes can aid in smoking cessation. With the rapid development of e-cigarettes, designers are constantly considering environmental issues and prioritizing the consumer experience.

[0003] Currently, e-cigarettes are broadly categorized into disposable and reusable types, with reusable e-cigarettes featuring replaceable e-liquid bottles. A problem arises when replacing or refilling the e-liquid bottle: if the bottle isn't promptly inserted into the e-cigarette after the cap is unscrewed, the e-liquid can easily evaporate; or, if the bottle is accidentally knocked over or inverted, the e-liquid can easily leak. Utility Model Content

[0004] In view of the above technical problems, this utility model provides a press-operated oil bottle and electronic cigarette to solve the over-pressure or under-pressure defects of the oil tank in the prior art of electronic cigarettes.

[0005] Other features and advantages of this invention will become apparent from the following detailed description, or may be learned in part by practice of this invention.

[0006] According to one aspect of this utility model, a press-operated oil bottle is disclosed, comprising a bottle body, a fastening ring provided at the bottle mouth of the bottle body, a piston provided inside the fastening ring, a sealing ring installed at the tail of the piston, and a spring fitted on its body. An oil inlet hole and an oil delivery channel are formed on the piston. Under normal conditions, the restoring force of the spring causes the sealing ring at the tail of the piston to tightly contact the fastening ring, so that the bottle body is sealed and the oil inlet hole is hidden inside the fastening ring. When the piston is squeezed and moves into the bottle body, the oil inlet hole is exposed inside the bottle body, and the spring is in a compressed or extended state.

[0007] Furthermore, the bottom of the fastening ring is bent inward to support and limit the spring, and a flange is formed on the top of the piston to limit the spring.

[0008] Furthermore, the bottle body has threads on the outside of the bottle opening.

[0009] According to a second aspect of this disclosure, an electronic cigarette is disclosed, including the aforementioned oil bottle and an oil reservoir. An oil guide tube is provided inside the oil reservoir, extending outside the oil reservoir. An oil guide plug is provided inside the oil guide tube. When the oil bottle is connected to the oil reservoir, the oil guide plug squeezes the piston. The interior of the oil bottle is connected to the oil guide tube through the oil inlet and the oil delivery channel.

[0010] Furthermore, the oil tank is also equipped with an atomizing core assembly, which is connected to a mouthpiece located above the oil tank.

[0011] Furthermore, the electronic cigarette includes a body assembly and a cartridge assembly. The cartridge assembly includes the oil bottle, the oil tank, and the mouthpiece. The body assembly includes a circuit board and a battery. The body assembly and the cartridge assembly are detachably connected. The cartridge assembly is provided with a spring pin that is electrically connected to the atomizing core assembly. The body assembly is provided with contacts that are electrically connected to the circuit board and the battery. When the body assembly and the cartridge assembly are connected, the spring pin contacts the contacts.

[0012] By adopting the above solution, the beneficial effects of this utility model are:

[0013] Thanks to the piston and spring at the bottle opening, the e-liquid inside will not easily leak even if the bottle is tipped over or turned upside down. The e-liquid can only flow out after the guide plug is inserted, effectively protecting the e-liquid. Attached Figure Description

[0023] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0024] like Figure 1-4 As shown, a press-operated oil bottle includes a bottle body 11. A fastening ring 12 is provided at the bottle mouth of the bottle body 11. A piston 14 is provided inside the fastening ring 12. A sealing ring 13 is installed at the tail of the piston 14. A spring 15 is fitted on the piston 14. An oil inlet hole 142 is formed on the piston 14 and an oil delivery channel 143 is formed inside it. Under normal conditions, the restoring force of the spring 15 causes the sealing ring 13 at the tail of the piston 14 to be in close contact with the fastening ring 12, so that the bottle body 11 is sealed and the oil inlet hole 142 is hidden inside the fastening ring 12. When the piston 14 is squeezed and moves into the bottle body 11, the oil inlet hole 142 is exposed inside the bottle body 11, and the spring 15 is in a compressed or extended state.

[0025] The bottom of the fastening ring 12 is bent inward to support and limit the spring 15, and the top of the piston 14 has a flange 141, which limits the spring 15.

[0026] The bottle body 11 has a thread 111 on the outside of the bottle mouth.

[0027] According to another aspect of this embodiment, such as Figure 5-7 As shown, an electronic cigarette is provided, including the aforementioned oil bottle and an oil tank 16. An oil guide tube 17 is provided inside the oil tank 16 and extends to the outside of the oil tank 16. An oil guide plug 18 is provided inside the oil guide tube 17. When the oil bottle is connected to the oil tank 16, the oil guide plug 18 squeezes the piston 14. The inside of the oil bottle is connected to the oil guide tube 17 through an oil inlet hole 142 and an oil delivery channel 143.

[0028] The oil tank 16 is also equipped with an atomizing core assembly 19, which is connected to the mouthpiece 110 located above the oil tank 16.

[0029] The electronic cigarette includes a body assembly 2 and a cartridge assembly 1. The cartridge assembly 1 includes an oil bottle, an oil tank 16, and a mouthpiece 110. The body assembly 2 includes a circuit board and a battery. The body assembly 2 and the cartridge assembly 1 are detachably connected. The cartridge assembly 1 is provided with a spring pin 101 that is electrically connected to the atomizing core assembly 19. The body assembly 2 is provided with contacts that are electrically connected to the circuit board and the battery. When the body assembly 2 and the cartridge assembly 1 are connected, the spring pin contacts the contacts.

[0030] Working principle:

[0031] When inhaling an electronic cigarette, the airflow sensor located inside or outside the oil tank 16 senses the inhalation action and transmits it to the main board. The main board control contacts are energized, and the power is conducted through the spring pin 101 to the atomizer core assembly 19. The atomizer core heats the e-liquid in the oil tank 16 to produce vapor, which is then drawn out from the mouthpiece 110.

[0032] When refilling e-liquid, the bottle body 11 is inserted into the protruding oil guide tube 17 below the oil tank 16. The oil guide plug 18 in the oil guide tube 17 pushes open the piston 14, causing the piston 14 to move downward and exposing the oil inlet 142. At this time, the e-cigarette is reversed, and the e-liquid enters the oil tank 16 along the oil inlet 142, the oil delivery channel 143, and the oil guide tube 17, completing the e-liquid refill. When the e-liquid bottle is pulled out, the spring 15, under the action of restoring force, forces the piston 14 to retract into the retaining ring 12. The sealing ring 13 on the piston 14 is only attached to the retaining ring 12, completing the seal and preventing e-liquid leakage.

[0033] Beneficial effects:

[0034] Based on the piston 14 and spring 15 set at the bottle opening, even if the bottle is overturned or turned upside down, the e-liquid inside the bottle will not easily leak out. The e-liquid can only flow out after the oil guide plug 18 is inserted, which effectively protects the e-liquid.
