Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and particularly relates to an electronic cigarette with an integrated support. Background Art

[0002] An electronic cigarette, as the name implies, is a type of cigarette product that is heated through an electric heating form. It is mainly used to simulate the feelings and behaviors of traditional cigarettes. An electronic cigarette usually consists of a battery, an electronic control device, and a cartridge with a heater (storing a certain amount of e-liquid). The battery supplies power to the electronic control device and the cartridge respectively. The electronic control device controls the heating of the cartridge. At the same time, the three of them need to be fixed and assembled together through a mounting housing respectively.

[0003] Currently, there are mainly two types of electronic cigarettes on the market for separately fixing the battery, the electronic control device, and the cartridge:

[0004] 1. The cartridge includes a mounting housing, and the cartridge is assembled as a single unit separately;

[0005] The electronic control device includes a mounting housing, and the electronic control device is assembled as a single unit separately;

[0006] Then, through the outer shell, the electronic control device, the battery, and the cartridge are sequentially placed inside the outer shell, and fixed through the forming and positioning mechanism on the outer shell. (For example, threads are provided on the outer wall of the cartridge and the inner wall of the outer shell respectively, and fixed through threaded connection; or; after the cartridge is clamped with the outer shell, it is fixed by pressing through the bottom cover of the outer shell)

[0007] 2. The cartridge includes an inner shell, and the cartridge is assembled as a single unit separately;

[0008] The electronic control device includes an outer shell, and the electronic control device is assembled as a single unit separately;

[0009] The inner shell and the outer shell are fixed by snap connection.

[0010] However, the above-mentioned cartridge and electronic control device are assembled separately using separate housings, and the assembly between them has the following disadvantages:

[0011] 1. This structural arrangement is complex, occupies a large space, and is not conducive to the miniaturization of the electronic cigarette;

[0012] 2. The required process steps for separate assembly are numerous, which is not conducive to automated assembly. Content of the Utility Model

[0013] The object of the present utility model is to overcome the above defects in the prior art, and provide an electronic cigarette with an integrated support. After fixing the atomizer, battery and electronic control unit respectively through the integrated support, the assembly of the electronic cigarette is completed by sleeving the bottom shell, which occupies a small space, has fewer automated assembly steps, and is conducive to automated assembly.

[0014] To achieve the above object, the present utility model provides an electronic cigarette with an integrated support, including the integrated support. The integrated support includes an upper shell, a middle shell provided at the bottom of the upper shell, and a lower shell provided at the bottom of the middle shell. The upper shell, middle shell and lower shell are integrally injection molded. A cartridge is sleeved on the upper shell. A battery electrically connected to the cartridge is installed on the middle shell. An electronic control unit electrically connected to the cartridge and the battery respectively is installed on the lower shell. A bottom shell is sleeved outside the integrated support.

[0015] Preferably, bump points for snap connection with the cartridge are respectively provided at both ends of the outer wall of the upper shell.

[0016] Preferably, a first annular sealing ring abutting against the inner wall of the cartridge is provided around the outer wall of the upper shell, and a second annular sealing ring abutting against the bottom shell is provided below the first annular sealing ring.

[0017] Preferably, a third annular sealing ring abutting against the bottom shell is provided around the outer wall of the lower shell.

[0018] Preferably, the middle shell includes a middle support plate provided at one end in the middle between the upper shell and the lower shell, and side baffles provided on both sides between the upper shell and the lower shell. A first placement cavity for installing the battery is formed between the middle support plate and the two side baffles.

[0019] Preferably, a plurality of ribs are connected between the middle support plate and the lower shell.

[0020] Preferably, the side baffles are arc-shaped.

[0021] Preferably, battery anti-slip strips are respectively provided on both sides of the bottom of the placement cavity.

[0022] Preferably, a second placement cavity for installing the electronic control unit is provided inside the lower shell.

[0023] Preferably, a plurality of mounting convex columns protrude inside the lower shell. A silica gel pad is installed at the bottom of the bottom shell. The silica gel pad, the bottom of the bottom shell and the mounting convex columns of the lower shell are connected together by screws.

[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0025] 1. The integrated support of the present utility model, through the upper shell, middle shell and lower shell formed by integral injection molding, can successively complete the installation and fixation of the cartridge, battery and electronic control unit. At the same time, the cartridge, battery and electronic control unit can be directly electrically connected on the integrated support.

The silica gel pad 20, the bottom of the bottom shell 2 and the mounting studs 1301 of the lower housing 13 are connected together by screws.

[0045] In addition, the cartridge 3 of the embodiment of the present utility model adopts an atomizing core structure, which includes a cartridge 3 outer shell. The cartridge 3 outer shell is clamped with the upper housing 11. An oil chamber 32 is opened inside between the cartridge 3 outer shell and the upper housing 11. A ceramic core support 33 is installed at the bottom of the oil chamber 32. A ceramic atomizing core 35 is sleeved on the ceramic core support 33. Transition grooves 34 for contacting the e-liquid in the oil chamber 32 with the upper part of the ceramic atomizing core 35 are opened on both sides of the ceramic core support 33. A mouthpiece 31 is provided on the cartridge 3 outer shell and penetrates through the oil chamber 32 and is inserted on the ceramic core support 33. An atomizing channel 36 for contacting the lower part of the ceramic atomizing core 35 is provided between the ceramic core support 33 and the upper housing 11. The mouthpiece 31 is communicated with the atomizing channel 36. First absorbent cotton 37 is installed at both ends of the atomizing channel 36. Second absorbent cotton 38 is installed at the bottom between the two first absorbent cottons 37. A first silica gel sleeve 330 is sleeved on the top of the ceramic core support 33. A second silica gel sleeve 350 is sleeved on the top of the ceramic atomizing core 35.

[0046] Among them, the electrical connection method is: the ceramic atomizing core 35, the battery 4 and the electronic control unit 5 are respectively electrically connected;

[0047] Among them, the air flow mode is as follows:

[0048] First, the transition tank 34 and the mouthpiece 31 are independent of each other and do not communicate with each other;

[0049] Second, the oil tank 32, the transition tank 34 and the upper part of the ceramic atomizing core 35 are connected and communicated, which is convenient for the ceramic atomizing core 35 to absorb oil;
