[0026] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0027] It should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the technical product is usually placed when in use. They are only for the convenience of describing the present technology and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present technology. In addition, "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Therefore, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0028] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of this technology, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this technology can be understood according to specific circumstances.

[0030] See also Figure 1 and Figure 2 , a safe organic solvent delivery device, comprising a storage tank 1 and a temporary storage tank 4;

[0031] One end of the storage tank 1 is connected to a transport pipe 2, and the end of the transport pipe 2 away from the storage tank 1 is connected to a water pump 3, and the output end of the water pump 3 is connected to the inner cavity of the temporary storage tank 4 through a pipeline;

[0032] A movable part 5 is provided on the top of the storage tank 1, and a protrusion 6 is provided at one end of the movable part 5. The protrusion 6 movably contacts the touch sensor 7, and the touch sensor 7 is sequentially connected to the PLC controller 8, the relay 9, the water pump 3 and the power supply 10 through wires.

[0033] The transport pipe 2 at the top of the storage tank 1 cooperates with the water pump 3 to suck the organic solvent inside it and allow the organic solvent to enter the inner cavity of the temporary storage tank 4. During this process, the movable part 5 can be used to contact the touch sensor 7 to allow the PLC controller 8 to transmit a signal to the relay 9 to turn off the power supply 10, thereby turning off the water pump 3 to stop the suction work.

[0034] See also Figure 3 and Figure 4 The movable portion 5 of this embodiment includes a movable rod 501 , a floating ball 502 and a movable plate 503 . The floating ball 502 is arranged at the bottom of the movable rod 501 , and the movable plate 503 is arranged at the top of the movable rod 501 .

[0035] The movable rod 501 can slide freely up and down in the inner cavity of the storage tank 1, and the floating ball 502 can float on the organic solvent.

[0036] See also Figure 3 and Figure 4In this embodiment, one end of the movable rod 501 movably passes through the top of the storage tank 1 and extends to the outside of the storage tank 1 to be connected with the movable plate 503 , and the float 502 is located in the inner cavity of the storage tank 1 as a whole.

[0037] After the organic solvent inside the storage tank 1 is sucked out, the float 502 will contact the bottom of the storage tank 1, where the movable rod 501 moves downward, so that the protrusion 6 at the bottom of the movable plate 503 contacts the touch sensor 7, and then the touch sensor 7 is activated to transmit a signal to the PLC controller 8, thereby completing the power-off of the water pump 3.

[0038] See also Figure 2 , Figure 3 and Figure 4 In this embodiment, the protrusion 6 is fixedly mounted on one side of the bottom of the movable rod 501, the touch sensor 7 is fixedly mounted on one side of the top of the storage tank 1, and the bottom of the protrusion 6 corresponds to the contact end position of the touch sensor 7.

[0039] The bump 6 is located just on the top of the contact end of the touch sensor 7, so that when the movable rod 501 moves downward, the bump 6 touches the contact end of the touch sensor 7, thereby ensuring timely transmission of the signal.

[0040] See also Figure 1 and Figure 2 In this embodiment, the PLC controller 8 is installed on the side wall of the storage tank 1, the relay 9 is installed on the side wall of the storage tank 1 and is located below the PLC controller 8, and the power supply 10 is installed on the top of the temporary storage tank 4.

[0041] The model of the relay 9 is a JZC series DC contactor. The PLC controller 8 is used to transmit a signal to the relay 9 so that the relay 9 controls the disconnection of the power supply 10.

[0042] See also Figure 1 and Figure 2 In this embodiment, the inlet end of the transport pipe 2 is located at the bottom of the side wall of the storage tank 1 and is connected to the bottom of the inner cavity of the storage tank 1. The outlet end of the transport pipe 2 is located at the top of the temporary storage tank 4 and is connected to the top of the inner cavity of the temporary storage tank 4.

[0043] By inserting one end of the transport tube 2 into the bottom of the inner cavity of the storage tank 1, all the organic solvents in the inner cavity of the storage tank 1 can be sucked out to avoid the organic solvents at the bottom from being sucked out.

[0044] See also Figure 3 and Figure 4 In this embodiment, the movable plate 503 is designed to be circular as a whole, the cross section of the movable rod 501 is designed to be elliptical, and the through hole on the top of the storage tank 1 movably penetrated by the movable rod 501 is also elliptical.

[0045] The cross section of the movable rod 501 is elliptical, so that the movable rod 501 can be prevented from rotating freely and the protrusion 6 and the touch sensor 7 can be prevented from being misaligned.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
