[0022] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0023] The utility model discloses a double-chamber electronic cigarette, combined with Figures 1 to 8As shown, it includes a handle 1 and an upper cover 2, wherein the handle 1 is provided with an inner shell 3, a battery 4 and a PCB board 5, the inner shell 3 includes two bullet chambers 30 arranged side by side, the bullet chamber 30 is used to install a cigarette cartridge 100, a probe assembly 36 electrically contacting the cigarette cartridge 100 is provided at the bottom of the bullet chamber 30, the probe assembly 36 and the battery 4 are electrically connected to the PCB board 5 respectively, the two bullet chambers 30 both protrude above the handle 1, the upper cover 2 is sleeved on the top of the two bullet chambers 30, a cigarette holder 20 is fixed at the top of the upper cover 2, a pad 21 abutting against the cigarette holder 20 is provided in the upper cover 2, two cigarette cartridge connecting holes 22 are provided at the bottom of the pad 21, the two cigarette cartridge connecting holes 22 are respectively used to connect the mist outlets at the tops of the two cigarette cartridges 100, a smoke outlet 23 connected to the internal smoke duct of the cigarette holder 20 is provided at the top of the pad 21, and the two cigarette cartridge connecting holes 22 are both connected to the smoke outlet 23.

[0024] In the above structure, the inner shell 3 is fixed to the upper opening of the handle 1, and the upper cover 2 can be sleeved on the top of the two bullet chambers 30, and the upper cover 2 is tightly matched with the two bullet chambers 30, so that the cigarette cartridge 100 can be reliably fixed in the bullet chamber 30. When the cigarette cartridge 100 is working, the smoke sent out from its top enters the corresponding cigarette cartridge connecting hole 22, and the smoke sent out by the two cigarette cartridges 100 enters the smoke outlet 23 through the two cigarette cartridge connecting holes 22 for mixing, and then the mixed smoke is sent into the internal flue of the cigarette holder 20, so as to realize the mixed use of two cigarette cartridges. The utility model can flexibly mix a variety of flavors of smoke by replacing different cigarette cartridges, which better meets a variety of application needs. At the same time, when the user needs a single flavor of smoke, only one cigarette cartridge needs to be assembled, thereby meeting the needs of using a single cigarette cartridge.

[0025] As a preferred method, combined with Figure 3 and Figure 4 As shown, two recessed parts 220 are provided at the bottom of the cushion block 21, and the two recessed parts 220 are respectively used to sleeve the top ends of the two cigarette cartridges 100. Further, the recessed parts 220 are inner conical surface recessed parts.

[0026] In the above structure, the purpose of designing the inner conical surface recess is that its inner conical surface can be in close contact with the top edge of the cigarette cartridge 100, thereby ensuring good airtightness at the connection between the cushion block 21 and the cigarette cartridge 100.

[0027] See also Figure 4 The cigarette cartridge connecting hole 22 is oval in shape, and both cigarette cartridge connecting holes 22 extend toward the middle of the cushion block 21 .

[0028] In practical applications, a product position barrier may be provided, such as a silicone column that is the same size as the cigarette cartridge. When the user only needs a single flavor of smoke, a cigarette cartridge may be installed in one cartridge cavity 30, and the other cartridge cavity 30 may be blocked by a silicone column, thereby ensuring that a sufficient amount of aerosol is delivered by the cigarette cartridge 100.

[0029] As a preferred method, see Figure 3 The smoke collecting opening 23 is a strip-shaped slot. The strip-shaped and slot-shaped smoke collecting opening 23 provides a good mixing space for the two-way smoke, thereby fully mixing the smoke sent into the two smoke cartridge connecting holes 22.

[0030] As a preferred method, see Figure 5 The inner shell 3 includes a support plate 31 extending downward, and the PCB board 5 and the battery 4 are respectively arranged on the front and rear sides of the support plate 31. In this embodiment, the PCB board 5 and the battery 4 can be well separated by providing the support plate 31.

[0031] Furthermore, combined with Figure 6 and Figure 7 As shown, two V-shaped guide grooves 32 are formed on the front side of the support plate 31, and the V-shaped guide grooves 32 correspond to the bullet cavity 30 one by one. Two microphone seats 33 are formed on the rear side of the support plate 31, and the microphone seats 33 correspond to the V-shaped guide grooves 32 one by one. One end of the V-shaped guide groove 32 is connected to the bullet cavity 30 through a first air hole 34, and the other end of the V-shaped guide groove 32 is connected to the microphone seat 33 through a second air hole 35.

[0032] In the above structure, after the airflow passes through the microphone seat 33, it enters the V-shaped guide groove 32 through the second air hole 35. After the airflow turns through the V-shaped guide groove 32, it enters the bullet cavity 30 through the first air hole 34. The purpose of setting the V-shaped guide groove 32, the first air hole 34 and the second air hole 35 in this embodiment is to complicate the air path by adding inflection points, which not only increases the air resistance to simulate the smoking resistance, but also makes the airflow pass through the smoke cartridge 100 evenly, which can avoid insufficient smoke concentration in the airflow due to the airflow rushing through the smoke cartridge quickly. Compared with the prior art, the above-mentioned air path structure in this embodiment is helpful to improve the uniformity of smoke in the airflow and enhance the user experience.

[0033] In order to block the V-shaped guide groove 32, in this embodiment, a soft rubber pad 6 is provided in the handle 1, and the soft rubber pad 6 is tightly attached to the front side of the support plate 31, and the soft rubber pad 6 covers the two V-shaped guide grooves 32. Correspondingly, the pad 21 is also a silicone pad.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
