For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0041] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0042] Refer to Figures 1 to 5, which is the first embodiment of the present utility model, proposes an aerosol spraying device for leak detection in a clean room, which is used to spray aerosol at the air inlet of a clean area to create a harsh environment, including: a liquid storage tank 2 is arranged on a frame body 1, and the liquid storage tank 2 has a storage space 210; a feeding pipe 420 is connected to the liquid outlet 430 of a water pump, and the top of the feeding pipe 420 has an opening 421; a lifting pipe 440 is sleeved on the feeding pipe 420, and the lifting pipe 440 is slidably arranged at one end of the feeding pipe 420 away from the frame body 1, and there is a flow-through space 441 between the lifting pipe 440 and the feeding pipe 420; there are several spray heads 450, which are arranged at the top of the lifting pipe 440, and several spray heads 450 are all communicated with the flow-through space 441, and the spray heads 450 are used to spray liquid.

[0043] In this embodiment, the frame body 1 is used to bear the overall weight of the equipment. When in use, the spraying liquid bottle 3 is installed on the liquid storage tank 2, and the spraying liquid in the spraying liquid bottle 3 will gradually flow into the interior of the storage space 210 and gradually fill the storage space 210. The spraying liquid will enter the water pump through the liquid inlet, and after being pressurized by the water pump, it will be sent out through the feeding pipe 420. After reaching the opening 421 at the top of the feeding pipe 420, it will finally be sprayed out by the spray heads 450 at the top of the lifting pipe 440. The lifting pipe 440 can be lifted and lowered relative to the feeding pipe 420 to adjust the height of the liquid sprayed by the spray heads 450, ensuring that the device can be applied to different clean rooms and can also adapt to more complex terrains and environments. The lifting pipe 440 is slidably and sealingly arranged relative to the feeding pipe 420, which can ensure that the lifting pipe 440 will not leak during sliding, causing waste of liquid. The design of multiple spray heads 450 can ensure a larger spraying range during spraying, create a more complex environment, and improve the accuracy of detection.

[0044] As a further technical solution, it further includes: a limiting member 460 is slidably arranged on the feeding pipe 420, and the limiting member 460 is used to limit the position of the lifting pipe 440.

[0045] In this embodiment, the limiting member 460 is used to limit the position of the lifting pipe 440. In this solution, a clamp form is adopted to limit the position of the lifting pipe 440. It can also be the lifting pipe 440 or other ways that can achieve the same function. By adjusting the position of the limiting member 460, the lowest height of the lifting pipe 440 can be limited to ensure that the height of the spray head 450 can always be near the air inlet of the clean area, improving the detection effect. Adopting the clamp form can fix and adjust its position more conveniently and quickly, so as to be used more quickly, shorten the detection time, and improve the work efficiency.

[0046] As a further technical solution, it further includes: there are several mounting members 5, the mounting member 5 has a guiding space 510, several mounting members 5 are sequentially sleeved on the feeding pipe 420, there is a fluid space 520 between several mounting members 5 and the feeding pipe 420, and the guiding space 510, the fluid space 520 and the storage space 210 are sequentially communicated; a spraying liquid bottle 3, detachably arranged on the mounting member 5, and the spraying liquid bottle 3 is used to store the liquid to be sprayed and inject it into the guiding space 510.

[0047] In this embodiment, the mounting member 5 is an overall rotating structure and the multiple rotating members are sealed with each other. The heights of the multiple different rotating members are different. When in use, they can not only rotate together, which not only looks more beautiful, but also occupies a smaller volume. The guiding space 510 is inclined, and the end where the spraying liquid bottle 3 is installed is the highest. Such a design can ensure that the liquid in the spraying liquid bottle 3 will not remain in the guiding space 510 after flowing out, and can flow into the liquid storage tank 2 in time, preventing waste of the liquid. The inclined fluid space 520 can also prevent the mounting member 5 above from affecting the mounting member 5 below after the spraying liquid bottle 3 is installed on the mounting member 5 above, and will not cause liquid to flow out.

[0048] As a further technical solution, it further includes: an operation valve 530 is arranged on the mounting member 5, and the operation valve 530 is used to open or close the guiding space 510.

[0049] In this embodiment, the operation valve 530 is installed on the mounting member 5 to control the opening or closing of the guiding space 510. Through the design of the operation valve 530, it can not only prevent the unused mounting member 5 from affecting the mounting member 5 in use, but also after rotating several mounting members 5 to different positions and respectively installing the spraying liquid bottles 3, as long as the opening or closing of the specified operation valve 530 is controlled, the use of a specific liquid bottle can be realized, reducing the difficulty of changing the bottle.

[0050] As a further technical solution, the material outlet of the spraying liquid bottle 3 is located on the side, and it further includes: a support member 540 is arranged on the mounting member 5 in a lifting manner, and both ends of the support member 540 are respectively in contact with the frame body 1 and the spraying liquid bottle 3, and the support member 540 is used to assist the mounting member 5 to support the spraying liquid bottle 3.

[0051] In this embodiment, the support member 540 is installed on the mounting member 5. When the spraying liquid bottle 3 is installed, the outlet of the spraying liquid bottle 3 is aligned with the inlet of the guiding space 510 on the mounting member 5 to ensure that the liquid does not flow out from other places. Since the installation position of the spraying liquid bottle 3 is relatively high and the overall weight of the spraying liquid bottle 3 is large when it is full of liquid, long-term use may cause the seal between the mounting members 5 to fail or the deformation of the mounting member 5. Therefore, a plurality of support members 540 are designed to support the spraying liquid bottle 3. When the spraying liquid bottle 3 is installed on the mounting member 5, it will also abut against the support member 540. At this time, the weight of the liquid bottle will be borne by the support member 540 and will not act on the mounting member 5, effectively ensuring the service life of the mounting member 5, preventing problems that may occur after long-term use of the mounting member 5, and improving the reliability of the spraying device.

[0052] As a further technical solution, the lengths and diameters of the support members 540 on different mounting members 5 are different according to the positions of the mounting members 5. The support member 540 is a hollow structure, and a plurality of different support members 540 can be coaxially installed.

[0053] In this embodiment, the sizes and diameters of the support members 540 on different mounting members 5 are different, and different mounting members 5 can adapt to the mounting members 5 located at different positions. When the mounting members 5 are installed, corresponding support members 540 support them, improving the service life of the equipment. The diameters of different support members 540 are also different. The smaller the diameter of the support member 540 used for the mounting member 5 with a higher height. Through the lifting of the support member 540 on the mounting member 5 and the rotation of the mounting member 5 itself, a plurality of different mounting members 5 can be coaxially installed. At this time, the area occupied by the plurality of mounting members 5 is the smallest, and only the uppermost spraying liquid bottle 3 can be installed. After the plurality of different mounting members 5 are rotated to different angles, different liquid bottles can be installed and used respectively, and their corresponding support members 540 can also specifically support different liquid bottles to ensure the service life of the mounting member 5.

[0054] As a further technical solution, the outer wall of the lifting pipe 440 has teeth 442, and further includes: a first rotation driving member 6 is arranged on the frame body 1, and the first rotation driving member 6 has a first output end 610; a gear 620 is arranged on the first output end 610, and the gear 620 meshes with the teeth 442, and the first rotation driving member 6 is used to drive the lifting pipe 440 to rotate.

[0055] In this embodiment, the outer surface of the lifting pipe 440 has teeth 442. When the first rotation driving member 6 rotates, the gear 620 can drive the lifting pipe 440 to rotate, ensuring that the spraying range of the nozzle 450 on the lifting pipe 440 is wider and making the environment created by the device more realistic. The first rotation driving member 6 is a motor, and it can also be a motor or other devices that can play the same role. Driven by the first rotation driving member 6, its rotation can be more stable, and at the same time, the control is more convenient, improving the use experience of the spraying device.

[0056] As a further technical solution, it further includes: there are several wheels 7, which are arranged on the frame 1, and the wheels 7 are used to drive the frame 1 to move; there are several second rotation driving members 8, which are arranged on the frame 1, and the second rotation driving members 8 are used to drive the wheels 7 to rotate.

[0057] In this embodiment, there are several wheels 7 on the frame 1. When the spraying device is in use, the movement of the frame 1 can be realized by adjusting the second rotation driving member 8, ensuring a larger spraying range and making the environment created by the device more realistic. The design of the wheels 7 can also ensure that the device itself is more flexible, reducing the difficulty of handling and improving the use experience of the device.

[0058] As a further technical solution, the liquid storage tank 2 is provided with a recovery pipe 9. The recovery pipe 9 is located at the bottom of the storage space 210 and is used to discharge the unsprayed liquid.

[0059] In this embodiment, after use, there may be residual liquid in the flow-through space 441 between the lifting pipe 440 and the feed pipe 420 and in the storage space 210 of the liquid storage tank 2. At this time, the height of the lifting pipe 440 can be adjusted to make the liquid in the flow-through space 441 flow back into the storage space 210, and finally, recovery is achieved through the recovery pipe 9. The recovery pipe 9 located at the bottom of the storage space 210 can ensure that the liquid can discharge the liquid in the storage space 210 as completely as possible, preventing waste of the sprayed liquid and making the cleaning of the device faster and more convenient.

[0060] As a further technical solution, it further includes: a storage battery 10 is arranged on the frame 1, and the storage battery 10 is used to store electric energy and supply power to the first rotation driving member 6 and the second rotation driving member 8.

[0061] In this embodiment, the storage battery 10 is used to store the electric energy required by the device. At the same time, the weight of the storage battery 10 itself can also lower the overall center of gravity, prevent the device from tipping over, and improve the stability of the device during use.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
