Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those ordinarily skilled in the art without doing creative work shall fall within the protection scope of the present disclosure.
Referring to FIG. 5 to FIG. 8, an electronic cigarette liquid bottle in an embodiment of the present disclosure is provided.
The electronic cigarette liquid bottle 1 is configured to be assembled on a cartridge assembly and is configured to add electronic cigarette liquid to an atomizing core 2 when assembled onto the cartridge assembly.
The electronic cigarette liquid bottle 1 includes a bottle body 11, a first sealing rubber member 12, and a bracket 13. A first liquid chamber 16 with a first opening 110 on one side is formed in the bottle body 11, and the first liquid chamber 16 is configured to store electronic cigarette liquid. At least a portion of the first sealing rubber member 12 is arranged at the first opening 110; a side wall of the first sealing rubber member 12 is in interference fit with the bottle body 11; and a first liquid outlet hole 121 communicated to the first liquid chamber 16 is provided on the first sealing rubber member 12. The bracket 13 is arranged in the bottle body 11; and second liquid outlet hole 131 communicated to the first liquid outlet hole 121 is provided on the bracket 13. The first sealing rubber member 12 is movably provided with a sealing rubber plug 14; and the sealing rubber plug 14 is placed in the first liquid outlet hole 121 and/or the second liquid outlet hole 131 when the electronic cigarette liquid bottle 1 is not assembled on the cartridge assembly, to seal the first liquid outlet hole 121 and/or the second liquid outlet hole 131. The sealing rubber plug 14 is separated from the first liquid outlet hole 121 and the second liquid outlet hole 131 under a pushing action of a pushing member 31 of the cartridge assembly when the electronic cigarette liquid bottle 1 is assembled onto the cartridge assembly.
In this embodiment, by the arrangement of the first sealing rubber member 12 and the bracket 13 in the electronic cigarette liquid bottle 1, the first opening 110 of the bottle body 11 can be sealed. Furthermore, the first liquid outlet hole 121 and the second liquid outlet hole 131 are separately provided on the first sealing rubber member 12 and the bracket 13, and the sealing rubber plug 14 are movably arranged in the first liquid outlet hole 121 and/or the second liquid outlet hole 131, so that when the sealing rubber plug 14 is placed in the first liquid outlet hole 121 and/or the second liquid outlet hole 131, the first liquid chamber 16 is sealed. Furthermore, when the electronic cigarette liquid bottle 1 is assembled on the cartridge assembly, the pushing member 31 of the cartridge assembly pushes the sealing rubber plug 14 to be separated from the first liquid outlet hole 121 and the second liquid outlet hole 131 to open the first liquid outlet hole 121 and the second liquid outlet hole 131, so that electronic cigarette liquid in the first liquid chamber 16 can flow out through the first liquid outlet hole 121 and the second liquid outlet hole 131 in sequence, thereby adding electronic cigarette liquid into the cartridge assembly. Meanwhile, the electronic cigarette liquid bottle 1 has a simple structure; the production cost of the electronic cigarette liquid bottle 1 can be effectively reduced; the production can be facilitated; and the production time can be shortened.
In this embodiment, a pulling portion 141 is arranged on the sealing rubber plug 14; and an outer contour of a cross section of the pulling portion 141 is smaller than an outer contour of a cross section of the first liquid outlet hole 121 and smaller than an outer contour of a cross section of the second liquid outlet hole 131, so that the pulling portion 141 can pass through the first liquid outlet hole 121 and the second liquid outlet hole 131 in sequence from the inside of the first liquid chamber 16 and is then placed on an outer side of the first liquid chamber 16. In this way, the first sealing rubber member 12 and the bracket 13 can be mounted on the bottle body 11, and the sealing rubber plug 14 can be placed in the first liquid chamber 16, so that a portion of the pulling portion 141 is placed outside the first liquid chamber 16, and the electronic cigarette liquid can be injected into the first liquid chamber 16 from the second liquid outlet hole 131 and the first liquid outlet hole 121; and the sealing rubber plug 14 is then placed in the first liquid outlet hole 121 or the second liquid outlet hole 131 by pulling the pulling portion 141, so as to seal the first liquid chamber 16 and prevent the electronic cigarette liquid from leaking. Of course, before the bottle body 11 is provided with the first sealing rubber member 12 and the bracket 13, the electronic cigarette liquid can be directly injected into the first liquid chamber 16. Next, the first sealing rubber member 12 and the bracket 13 are mounted. In this process, excessive air will be discharged from the first liquid outlet hole 121 or the second liquid outlet hole 131, and the sealing rubber plug 14 is then placed in the first liquid outlet hole 121 or the second liquid outlet hole 131 by pulling the pulling portion 141, so as to seal the first liquid chamber 16. This can inject the electronic cigarette liquid into the electronic cigarette liquid bottle 1 too.
In an embodiment, a break gap 142 is provided at a position, close to the sealing rubber plug 14, on the pulling portion 141. When the sealing rubber plug 14 is arranged in the first liquid outlet hole 121 and/or the second liquid outlet hole 131, the pulling portion 141 is pulled to be broken from the break gap 142. By the arrangement of the break gap 142, when the electronic cigarette liquid bottle 1 is assembled on the cartridge assembly, the pulling portion 141 is pulled to be broken first to prevent the redundant pulling portion 141 from affecting the assembling of the electronic cigarette liquid bottle 1 on the cartridge assembly.
