DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0025] Please refer to Figure 1 and Figures 3 to 5 , the present invention provides a technical solution:

[0026] A pneumatic vacuum extractor, comprising:

[0027] A liquid pipe 11, on which a liquid pipe switch 9 for controlling the liquid flow is provided. One end of the liquid pipe 11 has a hook-shaped liquid suction nozzle 12 for convenient suction. The other end of the liquid pipe 11 is connected to a sealed container 100 through a liquid pipe interface 202 in a pipeline manner;

[0028] A vacuum device 3, which has a vacuum generator 5 for creating a negative pressure environment in the liquid supply bottle 1 to suck liquid through the hook-shaped liquid suction nozzle 12. The vacuum generator 5 is connected to a gas pipe interface 201 on the sealed container 100 through a gas pipe 10.

[0029] In this embodiment, when the engine cleaning work is completed, there is still cleaning liquid remaining in the cylinder. At this time, first, the vacuum device 3 and the liquid pipe 11 need to be connected to the liquid bottle cap 2.

[0030] Start the vacuum device switch 8 on the vacuum device 3, and the vacuum generator 5 will start to work. Through the Venturi effect and Bernoulli principle, a vacuum is formed in the liquid bottle cap 2. Open the valve 901 of the liquid pipe switch 9 at the other end of the liquid pipe 11, and the hook-shaped liquid suction nozzle 12 can easily extend into the dead corners that other devices in the cylinder cannot reach to suck the remaining cleaning liquid.

[0031] Specifically, the sealed container 100 includes a liquid supply bottle 1. The top of the liquid supply bottle 1 is threadedly connected with a liquid bottle cap 2 for connecting a hose. Both sides of the liquid bottle cap 2 are respectively provided with a gas pipe interface 201 for connecting the gas pipe 10 and a liquid pipe interface 202 for connecting the liquid pipe 11.

[0032] Specifically, as Figure 3 shown, the bottom edge of the bottle cap of the liquid bottle cap 2 has a sealing ring 203 for sealing to prevent air leakage. A through hole 204 is provided at the center of the bottom to allow the sucked liquid to flow into the liquid supply bottle.

[0033] Specifically, one end of the liquid pipe 11 is connected to the liquid bottle cap 2, and the other end is connected to the liquid pipe switch 9. A valve 901 is installed on the liquid pipe switch 9.

[0034] Specifically, the shape and specifications of the hook-shaped liquid suction nozzle 12 are not fixed, and different liquid suction nozzles can be replaced according to the required scenarios.

[0035] To prevent a series of safety accidents such as explosion caused by excessive pressure, the pressure switch 7 installed in the vacuum device 3 continuously monitors the pressure condition and displays the data through the pressure gauge 6. When the pressure exceeds the safety threshold preset by the pressure switch 7, the pressure switch 7 will control the vacuum device 3 to stop working until the pressure drops to the safe range before it can be started again.

[0036] Specifically, as Figure 5 shown, the vacuum generator 5 is connected to the tracheal interface 201 through the trachea 10. A pressure reducing port 4 is installed at the top of the vacuum generator 5, and a pressure gauge 6 is installed at the bottom.

[0037] Specifically, a pressure switch is installed on the side of the pressure gauge 6, and a vacuum device switch 8 is installed at the bottom of the pressure gauge 6. Embodiment

[0038] Please refer to Figure 2 , the present utility model provides a technical solution, which is basically the same as that of Embodiment 1, with the slight difference that:

[0039] The sealed container 100 includes a funnel assembly 13. A funnel cover 133 for convenient opening and cleaning is threadedly connected to the top of the funnel assembly 13. The two sides of the funnel assembly 13 are respectively provided with a tracheal interface 201 and a liquid pipe interface 202.

[0040] In this embodiment, when using a small-mouth container, by using the funnel assembly 13 to replace the sealed container (100) in Embodiment 1, after the vacuum device 3 is started, a vacuum is formed in the funnel 131. The hook-shaped liquid suction nozzle 12 is used to suck the liquid from the liquid pipe into the funnel 131. When the funnel 131 is full of liquid or the suction is completed, the vacuum device 3 is turned off, and the liquid outlet 132 is inserted into the small-mouth container. At this time, the funnel switch 134 is opened, and the liquid sucked into the funnel 131 will flow into the container along the liquid outlet 132.

[0041] If you want to continue sucking, just close the funnel switch 134 and turn on the vacuum device 3 to continue working. If you don't need to continue working, you can open the funnel combination 3 by rotating the funnel cover 133 to clean the inside for the next use.

[0042] Specifically, a funnel switch 134 for controlling the dripping of the funnel is installed on the funnel assembly 13, and the bottom of the funnel assembly 13 has a liquid outlet 132.

[0043] Specifically, the shape and structure of the funnel assembly 13 are not unique, and it only needs to achieve the function of forming a vacuum to suck the liquid and complete the feeding into the container.

[0044] For the rest of the present utility model that is not described, it can be the same as the prior art, or be well-known technology, or can be implemented by using the prior art, and will not be elaborated here.

[0045] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
