Description

Technical Field

[0001] The utility model relates to an air intake device of an atomizer, belonging to the technical field of medical atomizers. Background Art

[0002] The main noise source of an atomizer is a compressor (air pump). At present, the air inlet on the shell of a DC compression atomizer is directly connected to the compressor inside the shell. The gas outside the shell enters the compressor through the air inlet and is compressed. The noise generated when the compressor works will spread along the pipeline, and a large amount of noise will directly spread to the outside of the shell through the air inlet, which brings an uncomfortable experience to users. Content of the Utility Model

[0003] In order to overcome the problems existing in the prior art, the utility model provides an air intake device of an atomizer, which helps to reduce the noise of the atomizer. The specific technical solutions are as follows.

[0004] An air intake device of an atomizer, the atomizer includes a shell, and is characterized in that: the air intake device includes a cylindrical part, a filtering element and a cover part, the cover part is arranged at the outer end of the cylindrical part, and the filtering element is located in the inner cavity of the cylindrical part; air intake holes are arranged on the side wall of the cylindrical part, and a through hole is arranged at the inner end of the cylindrical part; the air intake holes are located inside the shell.

[0005] By adopting the above technical solution, the air intake holes of the air intake device are arranged inside the shell. When the compressor of the atomizer works, the noise generated by it will not be directly transmitted to the outside of the shell when it reaches the air intake holes, but will be transmitted to the inside of the shell. Therefore, the noise of the compressor can be significantly reduced.

[0006] Furthermore, a heat dissipation air inlet and a heat dissipation air outlet are arranged on the shell. When the air outside the shell enters the inside of the shell through the heat dissipation air inlet, a part of the heat dissipation air is discharged from the heat dissipation air outlet, and a part of the heat dissipation air enters the inner cavity of the cylindrical part through the air intake holes, and after being filtered by the filtering element, it enters the downstream compressor through the through hole. After the noise generated by the compressor is transmitted to the inside of the shell from the air intake holes, the huge space inside the shell has a good noise reduction effect, and finally a part of the noise will be transmitted to the outside of the shell through the heat dissipation air inlet and the heat dissipation air outlet.

[0007] Furthermore, the cylindrical part has a flange on the outside, and the flange is spliced with the shell. The part of the cylindrical part located inside the flange (including the air intake holes) is located inside the shell, and the part of the cylindrical part located outside the flange is located outside the shell. The flange is spliced with the shell, so that the cover part can be exposed outside the shell, which is convenient for disassembling the cover part to replace the filtering element. Preferably, the shell includes an upper shell and a lower shell, and the upper shell has a notch for accommodating the flange.

[0008] Further, a plug-in portion is provided on the flange. This facilitates the assembly of the air intake device to the housing or other components in a plug-in manner, improving the assembly efficiency.

[0009] Further, the cover portion has a sleeve located in the inner cavity of the cylindrical member, and at least a part of the filter element is located within the sleeve. By providing the sleeve, it is beneficial to movably arrange the cover portion on the cylindrical member, and the sleeve can be engaged with the cylindrical member in a sleeved form. Preferably, a sealing ring is sleeved on the sleeve. By providing the sealing ring, on the one hand, it realizes the sealing and tight connection between the cylindrical member and the cover portion, and on the other hand, it can prevent noise from being conducted from between the cylindrical member and the cover portion to the outside of the housing. Preferably, the outer diameter of the filter element is smaller than the inner diameter of the cylindrical member, and the outer diameter of the filter element is adapted to the inner diameter of the sleeve. This setting enables the filter element to be stably fixed without shaking. There is a certain gap between the filter element and the cylindrical member, and the air entering from the air intake hole first reaches this gap and then is filtered by the filter element, ensuring the air volume and smoothness of the air flow.

[0010] Further, a card slot is provided on the sleeve, and a rib is provided on the inner wall of the cylindrical member corresponding to the card slot. When the sleeve is inserted into the inner part of the cylindrical member, the card slot and the rib cooperate with each other to be clamped tightly, which is beneficial to enhancing the connection between the cylindrical member and the cover portion.

[0011] By arranging the air intake hole of the air intake device of the atomizer of the present utility model inside the housing, it helps to reduce the noise of the compressor conducted to the outside of the housing, enhancing the user experience. Description of the Drawings
