AI Technical Summary
When you stop using an e-cigarette containing e-liquid, the air pressure balance before and after the microphone resets slowly, which may cause the atomizer coil to continue working and result in e-liquid leakage.
An exhaust channel is installed in the electronic cigarette to connect the front and rear cavities of the microphone, and the air intake channel is sealed with a sealing plug to form a rapid air pressure balance and prevent oil leakage.
It achieves rapid microphone pressure balance, extends working time, enhances inhalation, prevents e-liquid leakage, and improves atomization.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an open-oil electronic cigarette with an exhaust groove. Background Technology
[0002] E-cigarettes with a clear vapor chamber typically control the atomizer coil's activation via the microphone. During inhalation, a pressure difference is created across the microphone, causing it to operate. When inhalation stops, the pressure across the microphone equalizes, and the microphone stops working. To achieve microphone control, the microphone's airway is usually connected to the main airway; however, this can easily lead to leakage. Furthermore, the pressure equalization process across the microphone is slow, meaning the atomizer coil may remain active for an extended period after inhalation stops. Utility Model Content
[0003] The technical problem solved by this invention is to provide an open-oil electronic cigarette with an exhaust groove; it can quickly balance the air pressure before and after the microphone and avoid the problem of oil leakage.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:
[0005] The electronic cigarette includes a battery holder, a microphone, and microphone silicone; the battery holder is provided with an air intake channel; an accommodating space is provided outside the air intake channel, and the microphone and microphone silicone are placed in the accommodating space; the accommodating space is provided with a microphone air intake hole communicating with the air intake channel; the characteristic feature is that an exhaust groove is provided between the microphone silicone and the inner wall of the accommodating space to connect the front and rear cavities of the microphone.
[0006] A sealing plug is installed inside the air intake channel above the microphone air intake hole.
[0007] The microphone head is embedded in the upper end of the silicone microphone, and an exhaust groove is provided between the bottom and the accommodating space.
[0008] The microphone air inlet is located on the air intake channel near the exhaust slot.
[0009] This invention creates air channels on both sides of the microphone through the exhaust groove; when inhalation stops, the air pressure in front of and behind the microphone can quickly reach equilibrium; this extends the microphone's working time, improves the inhalation feel, and achieves better atomization. The sealing plug can also block the air intake channel when not in use, preventing e-liquid leakage. Attached Figure Description
[0010] The present invention will be further described below with reference to the accompanying drawings:
[0011] Figure 1 This is a cross-sectional view of the electronic cigarette of this utility model;
[0012] Figure 2This is a schematic diagram of the airflow state of the electronic cigarette according to this utility model. Detailed Implementation
[0013] The following embodiments are descriptions of specific implementations of the present utility model. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present utility model. All equivalent transformations that can be obtained from the description of the embodiments of the present utility model should be within the scope of protection of the present utility model.
[0014] like Figure 1 , 2 As shown, the electronic cigarette of this utility model includes a battery holder 1, a microphone 2, and a microphone silicone 3. The battery holder 1 is provided with an air intake channel 11; an accommodating space 12 is provided on the outside of the air intake channel 11.
[0015] The microphone silicone 3 has the microphone 2 embedded in its upper end and is placed within the receiving space 12. An exhaust groove 4 is provided between the bottom of the microphone silicone 3 and the receiving space 12; the exhaust groove 4 connects the front and rear cavities of the microphone 2.
[0016] A microphone air inlet 13 is provided on the air intake channel 11, near the exhaust slot 4; the microphone air inlet 13 connects the accommodating space 12 and the air intake channel 11. A sealing plug 5 is installed inside the air intake channel 11 above the microphone air inlet 13.
[0017] Before use, remove the sealing plug 5; then draw air through the mouthpiece; the airflow enters the air intake channel 11; simultaneously, the air on the side of the microphone 2 closest to the microphone air intake 13 is quickly drawn away, creating a pressure difference. The microphone starts, controlling the atomizing core to work. When drawing air stops, the exhaust groove 4 quickly balances the air pressure difference between the front and back sides of the microphone 2, ensuring that the microphone 2 stops working quickly.
[0018] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. The remaining parts are not related to the implementation of the aforementioned scheme; they will not be described in detail here.
