Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarette atomizers, and more particularly to an electronic cigarette with a structure for reducing airflow noise. Background Art

[0002] Existing electronic cigarettes or electronic atomization devices generally include a power supply assembly and an atomizer. The power supply assembly is equipped with a battery, which supplies power to the atomizer. When the atomizer is powered on, it can heat the solution to be atomized, namely the atomizing liquid or electronic cigarette liquid, and evaporate it into steam, electronic cigarette smoke or aerosol. The atomized liquid is stored in a liquid storage chamber provided inside the electronic cigarette atomizer.

[0003] When a user smokes in existing electronic cigarette atomizers, negative pressure is generated in the airflow channel and atomizer chamber. Airflow in the airflow channel accelerates when it encounters a narrow area, which can easily generate airflow noise. Existing electronic cigarettes have an air intake cavity at the connection between the power supply assembly and the atomizer. The air intake cavity is connected to the outside air through an air intake hole. The airflow noise generated by the atomizer during operation can be directly transmitted outward through the air intake hole, causing the user to hear a loud airflow noise, resulting in a poor smoking experience. Utility Model Content

[0009] Preferably, the circuit board is arranged on the bracket.

[0010] Preferably, the bracket further includes a bracket upper cover, and the circuit board is arranged between the bracket and the bracket upper cover.

[0011] The beneficial effect of the electronic cigarette with an airflow noise reduction structure of the present invention is as follows: the electronic cigarette is provided with an annular groove on the bracket of the power supply assembly, and the external air first enters the annular groove after the first air inlet hole. The air flows in the annular groove for a distance and then enters the air inlet cavity through the second air inlet hole. That is, the annular groove forms a buffer channel, so that the noise generated in the atomizer is transmitted outward through the annular groove and the first air inlet hole after passing through the air inlet cavity. The airflow noise is gradually weakened in the buffer channel of the annular groove, thereby reducing the transmission of the airflow noise and allowing users to obtain a better smoking experience.

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0018] The utility model has an electronic cigarette with a structure for reducing airflow noise. For the convenience of description, Figure 2 As shown, the atomizer of the electronic cigarette of the present invention is placed vertically with the atomizer facing upward. Any description of the components of the electronic cigarette herein such as “upper, lower, upper part, lower part, bottom, upper end, lower end, bottom end, above, below, bottom surface, upward, downward, horizontal, vertical” refers to the positional relationship of the components when the atomizer of the electronic cigarette is placed vertically with the atomizer facing upward.

[0019] Example

[0020] like Figure 1-Figure 5As shown, the electronic cigarette of the present invention, which features a structure for reducing airflow noise, consists of an atomizer 1 connected to a power supply assembly. The atomizer 1 has a mouthpiece 10 at its upper end, through which the user inhales. The airflow is automatically sensed within the atomizer 1, triggering a switch to automatically activate the electronic cigarette. During operation, the atomizer 1 automatically heats the atomized liquid, causing it to evaporate and produce an aerosol, or electronic cigarette smoke, which is then expelled from the mouthpiece 10.

[0021] The power supply assembly includes a hollow power supply housing 2, a bracket 3 disposed within the housing 2, a circuit board 4, and a battery pack 5. The circuit board 4, also known as a PCB control board, is fixed to the bracket 3. The battery pack 5 can be removed from the housing 2 and is an integrated component consisting of a charging device and battery cells. In this embodiment, to ensure a more secure and reliable installation of the circuit board 4, the bracket 3 is also covered with a bracket cover 6. The circuit board 4 is fixed between the bracket 3 and the bracket cover 6, providing better security and protection for the circuit board 4.

[0022] The connecting end of the atomizer 1 is connected to the connecting end of the power supply housing 2, the upper outer wall of the bracket 3 is sleeved on the inner wall of the connecting end of the power supply housing 2, the upper end face of the bracket 3 abuts against the end face of the connecting end of the atomizer 1, and the upper end face of the bracket 3 is recessed with an air intake cavity 30 so that when the atomizer 1 is working, it can provide inhaled air to the air intake channel provided on the end face of the connecting end of the atomizer 1.

[0023] An annular groove 31 is provided on the outer wall of the upper end of the bracket 3. A first air inlet hole 20 is provided on the wall of the power supply housing 2 at a location corresponding to the annular groove 31, communicating with the annular groove 31. A second air inlet hole 310 is provided at the bottom of the annular groove 31, communicating with the air inlet chamber 30. When the electronic cigarette is in use, suction is drawn into the atomizer 1, generating negative pressure in the air inlet chamber 30. Airflow flows through the airflow channel of the atomizer 1, accelerating when it encounters narrow areas. This can easily generate airflow noise within the atomizer 1. In existing electronic cigarettes, external air generally enters the air inlet chamber 30 directly through the first air inlet hole 20. Therefore, noise generated within the atomizer 1 can be directly transmitted outward through the air inlet chamber 30 and the first air inlet hole 20, resulting in a loud airflow noise audible to the user, resulting in a poor smoking experience. In the present invention, an annular groove 31 and a second air inlet hole 310 are provided. External air first enters the annular groove 31 after the first air inlet hole 20. The air flows in the annular groove 31 for a distance and then enters the air inlet chamber 30 through the second air inlet hole 310. The annular groove 31 forms a buffer channel, so that the noise generated in the atomizer 1 is conducted outward through the annular groove 31 and the first air inlet hole 20 after passing through the air inlet chamber 30. The airflow noise is gradually weakened in the buffer channel of the annular groove 31. That is, the first air inlet hole 20, the annular groove 31 and the second air inlet hole 310 are structures for reducing airflow noise, which can reduce the transmission of airflow noise and enable users to obtain a better smoking experience.

[0024] In this embodiment, the circumferential angle between the first air intake hole 20 and the second air intake hole 310 is greater than or equal to 90 degrees, so that the direction of airflow noise conduction forms a larger angle between the first air intake hole 20 and the second air intake hole 310, and the airflow noise has a longer stroke in the annular groove 31, so the airflow noise can be further weakened, thereby achieving a better noise reduction effect.

[0025] In other embodiments, the annular groove 31 has a zigzag line structure (not shown in the figures). The zigzag line structure also increases the stroke of the annular groove 31, and the airflow noise can be further reduced to achieve a better noise reduction effect.

[0026] In this embodiment, annular sealing grooves 32 are respectively provided on the upper and lower sides of the annular groove 31, and a sealing ring 7 is provided in the annular sealing groove 32. The sealing ring 7 can seal the gap between the bracket 3 and the power supply casing 2. This can prevent the airflow noise from passing through the air inlet cavity 30 or the annular sealing groove 32 and then being transmitted outward through the gap between the bracket 3 and the power supply casing 2, so that the airflow noise can be further weakened, thereby achieving a better noise reduction effect.

[0027] like Figure 2-Figure 4As shown in the figure, the direction of the continuous arrows AB is the direction in which air flows from the outside through the first air inlet hole 20, the annular sealing groove 32, the second air inlet hole 310, and the air inlet cavity 30 to the inside of the atomizer 1 when the electronic cigarette of the present invention is in operation, and the direction in which the atomized liquid is atomized in the atomizer 1 to generate aerosol and flow toward the mouthpiece 10.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various variations and modifications are possible within the technical scope of the present invention. Any modifications, alterations, or equivalent substitutions made by a person skilled in the art based on the above description are considered to be within the scope of protection of the present invention.
