Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to a smoking device with a replaceable oil storage tank. Background Art
[0002] As an electronic device, electronic cigarettes use heating elements to convert e-liquid into smoke for people to inhale. Electronic cigarettes mainly include three major aspects: oil storage structure, heating atomization structure, and battery structure. The oil storage capacity in the oil storage component varies depending on the type of electronic cigarette and relevant regulations of each country. For electronic cigarettes with small-capacity oil storage, we usually use disposable cartridges.

[0041] It can be understood that with such an arrangement, the magnetic force of the two first magnets 81 and the two second magnets 82 is used to establish the magnetic connection between the battery assembly 7 and the upper housing 2.
[0042] In order to realize the replaceability of the upper housing 2 as a cartridge, in this embodiment, refer to Figures 3 to 7 , one end of the upper housing 2 close to the battery assembly 7 is set as a plug-in part 21, the plug-in part 21 is inserted into the slot 31 of the lower housing 3, and the spring needle 73 and the second magnet 82 are located at the bottom of the slot 31.
[0043] It can be understood that with such an arrangement, the plug-in part 21 of the upper housing 2 and the slot 31 of the lower housing 3 are matched in shape. The upper housing 2 and the lower housing 3 are positioned by plugging and then fixed by magnetic force. The capacity of the oil cup 4 in the upper housing 2 is 2ML. As a small-capacity cartridge, the upper housing 2 can be quickly replaced by plugging and magnetic fixing, which is convenient for users to use cartridges with different flavors.
[0044] In order to fix the battery assembly 7 to the lower housing 3, in this embodiment, refer to Figure 5 and Figure 6 , a first clamping block 76 is arranged on the bracket 72, a first clamping groove is arranged on the inner wall of the lower housing 3, and the bracket 72 is fixed to the lower housing 3 by the first clamping block 76 being clamped into the first clamping groove.

Two opposite first clamping blocks 76 are formed on the bracket 72, and two second clamping grooves 25 are respectively formed on the inner walls of both sides of the lower housing 3. The bracket 72 is fixed to the lower housing 3 by clamping the two first clamping blocks 76 with the first clamping grooves, thereby fixing the battery assembly 7 inside the lower housing 3.
[0046] In order to form a cartridge with a better seal for the upper housing 2, in this embodiment, referring to Figure 4 and Figure 5 , a sealing silica gel 22 and a fixing frame 23 are provided inside the upper housing 2. The sealing silica gel 22 is fixed inside the upper housing 2 through the fixing frame 23, and an oil cup 4 is formed between the sealing silica gel 22 and the inner wall of the upper housing 2.
[0047] It can be understood that with such an arrangement, the sealing silica gel 22 is in interference fit with the inner wall of the upper housing 2 through its own elasticity, and the sealing silica gel 22 and the upper housing 2 are accurately positioned through the fixing frame 23, ensuring that a well-sealed oil cup 4 is formed between the sealing silica gel 22 and the inner wall of the upper housing 2.
[0048] In order to fix the fixing frame 23 to the upper housing 2, in this embodiment, referring to Figure 5 and Figure 7 , a second clamping block 24 is provided on the outer wall of the fixing frame 23, and a second clamping groove 25 is provided on the inner wall of the upper housing 2. The fixing frame 23 is fixed to the upper housing 2 by clamping the second clamping block 24 into the second clamping groove 25.
[0049] It can be understood that with such an arrangement, the two second clamping blocks 24 of the fixing frame 23 are clamped with the two second clamping grooves 25 of the insertion part 21 of the upper housing 2, thereby clamping and fixing the fixing frame 23 to the upper housing 2.
[0050] In order to form an oil injection structure that does not leak oil, in this embodiment, referring to Figure 4 , Figure 5 and Figure 7 , the sealing silica gel 22 is provided with a connecting pipe 26 extending into the mouth of the oil bottle 6, the pipe orifice of the connecting pipe 26 is an oil injection hole 41, and the fixing frame 23 is provided with a connecting pipe 27 on the outer circumference of the connecting pipe 26, and the connecting pipe 27 is threadedly connected to the oil bottle 6.
[0051] It can be understood that with such an arrangement, the elasticity of the sealing silica gel 22 itself can make the connecting pipe 26 in interference fit with the mouth of the oil bottle 6, thereby sealing between the mouth of the oil bottle 6 and the oil injection hole 41 and ensuring no oil leakage between the two.
[0052] In order to control the oil injection of the oil bottle 6, in this embodiment, referring to Figure 4 and Figure 5, the oil filling valve 5 includes a valve rod 51 and a valve cap 52. The valve rod 51 is installed at the installation hole 28 of the upper shell 2 through a sealing plug 53 and is arranged in the direction of the oil filling hole 41. The valve cap 52 is arranged outside the upper shell 2. The valve rod 51 is fixedly connected to the valve cap 52. The position of the valve rod 51 relative to the oil filling hole 41 is controlled through the valve cap 52 to block or open the oil filling hole 41.
[0053] It should be further noted that a positioning ring 54 is circumferentially arranged on the outer periphery of the installation hole 28 of the upper shell 2. The inner wall of the valve cap 52 is fitted with the positioning ring 54. When the valve rod 51 is inserted into the oil filling hole 41 to block the oil filling hole 41, the inner wall of the valve cap 52 is clamped with the outer wall of the positioning ring 54, and the connection relationship is maintained through the friction force between the two to prevent the valve cap 52 from separating from the positioning ring 54 by itself, resulting in the valve rod 51 following the valve cap 52 to open the oil filling hole 41 by itself.
[0054] It can be understood that with such a setting, the sealing plug 53 is made of silica gel. The sealing plug 53 seals between the installation hole 28 and the valve rod 51 through its own elasticity. The sealing plug 53 can slide with the outer wall of the valve rod 51, enabling the valve rod 51 to move relative to the sealing plug 53. In the state of blocking the oil filling hole 41, the outer wall of the valve rod 51 is in interference fit with the inner wall of the oil filling hole 41 to prevent the e-liquid in the oil cup 4 from flowing into the oil bottle 6. After the oil filling hole 41 is opened, the e-liquid in the oil bottle 6 can enter the oil cup 4 through the gap between the valve rod 51 and the inner wall of the oil filling hole 41 for oil filling.
[0055] In the embodiment of the present application, the outer shell 1 of the present application adopts the cooperation mode of the upper shell 2 and the lower shell 3, making the overall structure more compact and convenient for carrying and using. The upper shell 2 serves as the cartridge, and the lower shell 3 serves as the power supply host. The upper shell 2 is installed with the oil bottle 6 through threads. The oil bottle 6 serves as the oil storage chamber and can replenish e-liquid to the oil cup 4. The cartridge is connected to the lower shell 3 by means of plugging and magnetism. The oil bottle 6 is connected to the upper shell 2 by means of threads. Both the cartridge and the oil bottle 6 can be easily replaced. The replaceable cartridge can satisfy consumers' experience of different flavors, which is convenient for users and also takes into account environmental protection requirements.
[0056] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
