Description

Technical Field

[0001] The utility model belongs to the technical field of waste treatment and relates to a handheld automatic waste liquid collecting device controlled by a gravity switch. Background Art

[0002] At present, most chemical and biological laboratories in China only have rubber-tipped droppers and pipettes to recover residual waste liquid in containers such as test tubes and cell culture plates. Among them, the rubber-tipped dropper is purely manually operated and has low collection efficiency; and in high-risk work scenarios such as collecting hydrofluoric acid, it is easy to cause leakage due to improper operation, which in turn causes personal injury. Although pipettes are available in electric models, their capacity is too small and they are not suitable for waste liquid collection. As a result, there is a blank spot in the usage demand in this scenario that cannot be filled by existing products. Utility Model Content

[0003] The purpose of the utility model is to provide a handheld automatic waste liquid collection device controlled by a gravity switch in order to solve the above problems, which has good usability, high working efficiency, reliable structure and high safety.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A handheld automatic waste liquid collection device controlled by a gravity switch comprises a shell 1, wherein the shell 1 is divided into three parts: an upper structure 8, a middle structure 9 and a lower structure 10.

[0006] The upper structure 8 is a cylindrical structure, with an open bottom and a closed top, and a top circular hole 11 for passing the power line 6 at the top, and the bottom is open for routing to the middle structure 9. The transformer module 2 is installed in the upper structure 8; the top of the transformer module 2 is connected to the gravity switch 7 and the power line 6, and the power line 6 passes through the top circular hole 11 to connect to the external power supply.

[0007] The middle structure 9 is a cylindrical structure with a closed bottom and an open top, and two bottom circular holes 14 are provided at the bottom, one of which is used to connect to the water inlet 12, and the other is used to connect to the water outlet 13. A micro liquid pump 3 is installed in the middle structure 9, and the micro liquid pump 3 is connected to the transformer module 2 through a wire.

[0008] The lower structure 10 is a hollow integrated structure, with an opening at the top and a through hole at the bottom for installing the pointed straw 5. The top of the pointed straw 5 and two latex hoses 4 are installed inside the lower structure 10. A circular hole 15 is provided on the side wall of the lower structure 10, and two latex hoses 4 are installed inside. One end of one of the latex hoses 4 passes through the circular hole 15 to communicate with the water outlet 13, and the other end passes through the circular hole 15 to communicate with the outside world. Specifically, the other end is located outside the shell 1 (outside the circular hole 15 of the lower structure 10) and communicates with the outside world. The upper end of the second latex hose 4 is connected to the water inlet 12, and the lower end is connected to the pointed straw 5.

[0009] Further, when the pointed pipette 5 of the whole handheld automatic waste liquid collection device is facing downward, the gravity switch 7 is in a closed state, and the micro liquid pump 3 is powered on and starts to work. That is, the gravity switch 7 is installed in a closed direction toward the bottom of the device.

[0010] Furthermore, the micro liquid pump 3 is connected to the transformer module 2 via a wire, the transformer module 2 is connected to the gravity switch 7 via a wire, and the transformer module 2 is connected to an external power source via a power line 6 to form a loop.

[0011] Furthermore, in order to facilitate the replacement of the latex hose 4 and the pointed straw 5, the upper structure 8 and the middle structure 9 are connected by a snap-fit ​​connection, and the middle structure 9 and the lower structure 10 are connected by a snap-fit ​​connection.

[0012] Furthermore, the connection between the upper structure 8 and the middle structure 9 is sealed; the connection between the middle structure 9 and the lower structure 10 is sealed.

[0013] When the utility model is used, the handheld waste liquid automatic collection device controlled by the gravity switch is used as a liquid collection pen. The specific process is as follows:

[0014] First, the power cord 6 is passed through the top circular hole 11 to connect to an external power source, and the liquid collection pen is placed horizontally on the desktop. At this time, the liquid collection pen is powered on, but the gravity switch 7 is not closed, and the micro liquid pump 3 does not work.

[0015] When suctioning, hold the middle structure 9, place the liquid collection pen vertically, turn on the gravity switch of the gravity switch 7, and the micro liquid pump 3 starts to suction. The water flows in from the pointed straw 5, enters the cavity of the middle structure 9 along the second latex hose 4, and then flows out to the outside along the first latex hose 4, realizing the suction function and quickly transferring the waste liquid from the container to be cleaned to the waste liquid collection container.

[0016] When the suction is stopped, the liquid collection pen is placed horizontally on the desktop, the gravity switch 7 is turned off, the micro liquid pump 3 stops working, and the liquid collection pen stops working.

[0017] When the use is finished, the power cord 6 is disconnected from the external power source.

[0018] In addition, when the external power supply 4 needs to be replaced, the middle structure 9 is removed, the middle structure 9 is disconnected from the upper structure 8, and the latex hose 4 is directly removed and replaced.

[0019] The beneficial effects of the utility model are:

[0020] The device of the utility model is easy to operate and has high collection efficiency. Compared with the current method of using a rubber-tipped dropper to absorb waste liquid in laboratories, the use of this device not only greatly improves the efficiency of waste liquid collection, but also improves the safety of personnel in the scene of collecting hazardous waste liquid.
