[0036] like Figure 1-4 As shown, in an embodiment of the gas supply device, the gas supply device includes a first gas supply mechanism 1, a second gas supply mechanism 2, a first connecting pipeline 3 and an air outlet pipeline 4, the air outlet of the first gas supply mechanism 1 and the air outlet of the second gas supply mechanism 2 are both connected to the first connecting pipeline 3, the first gas supply mechanism 1 and the second gas supply mechanism 2 are both used to drive the gas flow, one end of the air outlet pipeline 4 is connected to the first connecting pipeline 3, and the other end is connected to the container, so that the first gas supply mechanism 1 and the second gas supply mechanism 2 can supply gas into the container.

[0037] In this embodiment, the air supply device of this embodiment includes a first air supply mechanism 1, a second air supply mechanism 2, a first connecting pipeline 3 and an air outlet pipeline 4. The air outlets of the first air supply mechanism 1 and the second air supply mechanism 2 are connected through the first connecting pipeline 3, and then connected to the air outlet pipeline 4. By sharing the first connecting pipeline 3, the connectivity relationship of the pipelines can be optimized and the construction cost of the pipelines can be reduced. It can also play the role of combining the first air supply mechanism 1 and the second air supply mechanism 2, thereby improving the air supply effect and solving the technical problems of the existing air supply device with complex structure and high cost.

[0038] Specifically, both the first air supply mechanism 1 and the second air supply mechanism 2 can be air pumps.

[0039] In an embodiment of the air supply device, the air supply device also includes a second connecting pipeline 5 and an air inlet pipeline 6. The air inlet on the first air supply mechanism 1 and the air inlet on the second air supply mechanism 2 are both connected to the second connecting pipeline 5. One end of the air inlet pipeline 6 is connected to the second connecting pipeline 5, and the other end is connected to the container, so that the first air supply mechanism 1 and the second air supply mechanism 2 can draw air to the outside through each of the air inlets.

[0040] In this embodiment, by setting up a second connecting pipeline 5, the first air supply mechanism 1 and the second air supply mechanism 2 can be connected in series and used in combination, just like the first connecting pipeline 3. Sharing the second connecting pipeline 5 can optimize the connectivity of the pipelines and reduce the construction cost of the pipelines.

[0041] In one embodiment of the air supply device, the air supply device further includes a connecting joint 7, which is provided with an air outlet channel and an air inlet channel. One end of the air outlet channel is connected to the air outlet pipeline 4, and the other end is connected to the container. The air inlet of the first air supply mechanism 1 and the air inlet of the second air supply mechanism 2 are both connected to the air inlet channel.

[0042] In this embodiment, by providing a connecting joint 7, the connecting joint 7 can replace the pipeline to connect to the container, which is convenient for connection with the container and can also achieve a stable connection effect, preventing the pipeline from shaking due to gas flow and affecting the connection between the pipeline and the container.

[0043] In the previous embodiments, the first air supply mechanism 1 and the second air supply mechanism 2 can directly inhale air from the outside through the air inlet to replenish the air source in turn. In this embodiment, the connecting joint 7 is provided with an air inlet channel in addition to the air outlet channel in the previous embodiments. The air inlets of the first air supply mechanism 1 and the second air supply mechanism 2 are both connected to the air inlet channel of the connecting joint 7, that is, the first air supply mechanism 1 and the second air supply mechanism 2 take in air and exhaust air through the connecting joint 7. In this way, the packaging can be convenient in the pipeline layout. The air supply device can encapsulate the first air supply mechanism 1 and the second air supply mechanism 2 on the packaging shell, and only needs to communicate with the outside world through the connecting joint 7, which can avoid opening multiple holes on the packaging shell.

[0044] In addition, in order to simultaneously open an air inlet channel and an air outlet channel on the connecting joint 7, specifically, in an embodiment of the air supply device, the connecting joint 7 includes a first connecting member 71 and a second connecting member 72, the first connecting member 71 is provided with a first groove 711, a third hole 712 and a fourth hole 713, the second connecting member 72 is provided with a first hole 724 and a second hole 726, the second connecting member 72 is at least partially accommodated in the first groove 711, the second connecting member 72 is spaced apart from the bottom of the first groove 711 to form a closed cavity 73, the first hole 724 is connected with the cavity 73, and the first connecting member 71 is provided with a third hole 712 on the side wall corresponding to the cavity 73, the first hole 724, the cavity 73 and the third hole 712 are connected in sequence to form an air inlet channel, the first connecting member 71 is also provided with a fourth hole 713, the second hole 726 is connected with the fourth hole 713 to form an air outlet channel, and the air outlet channel is isolated from the cavity 73.

[0045] In this embodiment, it can be understood that, in the construction of the air outlet channel, this embodiment realizes the construction of the air outlet channel by respectively opening holes on the first connecting member 71 and the second connecting member 72 and connecting the two holes, and in the construction of the air inlet channel, this embodiment first forms a closed cavity 73 through the installation relationship between the first connecting member 71 and the second connecting member 72. It should be emphasized that the cavity 73 is isolated and separated from the air outlet channel, and then separate holes are opened on the first connecting member 71 and the second connecting member 72 to cooperate with the cavity 73 to form the air inlet channel. In this way, the opening of the air inlet channel and the air outlet channel is realized through the cooperation of the two connecting members. The structural design is ingenious, the layout is reasonable and simple, and it is convenient for the staff to make connections.

[0046] Preferably, the second connecting member 72 can be threadedly connected to the side wall of the first groove 711 .

[0047] In an embodiment of the air supply device, a first protrusion 721 is provided at one end of the second connecting member 72 relative to the bottom of the first groove 711, and a hole is opened on the second connecting member 72 to pass through the first protrusion 721 to form a second hole 726. A ring member 714 is provided at the bottom of the first groove 711, and the fourth hole 713 is located in the ring member 714. The first protrusion 721 extends into the ring member 714 and is sealed with the ring member 714.

[0048] In this embodiment, specifically, the matching relationship between the first protrusion 721 and the annular member 714 is similar to the hole-shaft matching, and the two are plugged in. The sealing between the two can be achieved by setting a sealing ring 8 on the first protrusion 721 to achieve sealing with the annular member 714, that is, referring to Figure 4 The sealing ring 8 is sleeved in the gap between the first protrusion 721 and the annular member 714. In addition, it is understandable that the structures of the first protrusion 721 and the annular member 714 can both be through-connecting columns.

[0049] Preferably, the first protrusion 721 is integrally formed with the second connecting member 72 , and the annular member 714 is integrally formed with the first connecting member 71 .

[0050] In one embodiment of the air supply device, a second groove 723 is defined at one end of the second connecting member 72, which is away from the bottom of the first groove 711. A second protrusion 722 is defined at the bottom of the second groove 723, corresponding to the position of the first protrusion 721. A hole 726 is defined in the second connecting member 72, extending through the first protrusion 721, the bottom of the second groove 723, and the second protrusion 722.

[0051] In this embodiment, it is understood that the second protrusion 722 is protruding relative to the bottom of the second groove 723. In terms of axial length, the second protrusion 722 can be close to the notch of the second groove 723 or extend outside the second groove 723, so that it can be easily connected to the container. And after the container is connected to the second protrusion 722, the second groove 723 can be provided to avoid the container. The opening of the second groove 723 and the opening on the bottom of the second groove 723 can also be used to prevent the container from being damaged.

[0052] In an embodiment of the air supply device, the first hole 724 is opened at the bottom of the second groove 723 . There are multiple first holes 724 , and each first hole 724 is circumferentially arranged on the second protrusion 722 .

[0053] In this embodiment, in combination with the previous embodiment, by opening the second groove 723, after the container is first connected to the second protrusion 722, the second groove 723 can be provided to achieve an avoidance effect, and the first hole 724 is opened at the bottom of the second groove 723, which is close to the cavity 73, which can simplify the structural design, and is far away from the outlet of the first protrusion 721, so that the interior of the second groove 723 can be used as an extension of the air intake channel.

[0054] It should be emphasized that after the container is connected to the second protrusion 722, the notch of the second groove 723 is not closed. For this reason, the notch size of the second groove 723 can be selectively increased or the second protrusion 722 can be extended outside the second groove 723 according to the actual size of the container.

[0055] In combination with the previous embodiments, the air inlet and outlet processes of the air supply device of the present invention are explained. When the air is taken in, the gas enters the second groove 723 from the outside, and passes through the first hole 724, the cavity 73, the third hole 712, the air inlet pipe 6 and the second connecting pipe in sequence. When the air is discharged, the gas passes through the second connecting pipe 5, the air outlet pipe 4, the fourth hole 713 and the second hole 726 in sequence.

[0056] In an embodiment of the air supply device, a support column 725 is further provided at one end of the second connecting member 72 opposite to the first groove 711 , and the support column 725 abuts against the bottom of the first groove 711 .

[0057] In this embodiment, by providing a support column 725, when installing the first connecting member 71 and the second connecting member 72, the support column 725 can abut against the bottom of the first groove 711 to prevent the staff from further pressing and damaging the first connecting member 71 and the second connecting member 72.

[0058] The utility model also relates to an atomizing device, comprising a container and the air supply device in the above embodiment, wherein liquid is stored in the container, and the air supply device is used to supply air to the container and apply pressure, thereby atomizing and spraying the liquid in the container.

[0059] By applying the simple-structured and low-cost air supply device in the above embodiment, the cost of the overall atomization equipment can be further reduced, and the simplified air supply device is also more convenient to connect with the container.

[0060] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
