Description

Technical Field

[0001] This application relates to the field of experimental instrument technology, and in particular to a portable bottle-mouth dispensing controller. Background Technology

[0002] Bottle-top dispensers, as instruments for the precise transfer of liquid reagents, are widely used in quantitative dispensing, solution preparation, and sample processing. With the diversification of experimental scenarios, the demand for portable bottle-top dispensers is increasingly prominent.

[0003] Traditional bottle-top liquid dispensers have their inlet and outlet pipes packaged separately, meaning they are isolated from the main unit. This makes it easy for the pipes to be forgotten or left behind during transport, limiting their usability in specific scenarios. Furthermore, traditional bottle-top liquid dispensers have open inlet and outlet ports with no locking mechanisms, allowing external impurities to enter and affect the liquid. The movement of the casing also makes carrying the dispenser inconvenient.

[0004] Based on the above reasons, this utility model proposes a portable bottle mouth liquid dispensing controller that can realize the built-in storage of inlet and outlet liquid tubes, and at the same time has reliable sealing and stability effects. Utility Model Content

[0005] In view of the above problems, this application provides a portable bottle-mouth dispensing controller to solve the problem of the inconvenience of carrying traditional bottle-mouth dispensing controllers.

[0006] This application provides a portable bottle-mouth dispensing controller, including a circular shell, a piston disposed inside the circular shell, a fixed rod fixedly connected to the center of the top surface of the piston, the top end of the fixed rod penetrating the circular shell and fixedly connected to a movable shell, a vertical groove opened on the movable shell and a scale fixedly connected thereto, an annular plate movably connected between the movable shell and the circular shell, a positioning component disposed on the annular plate and a plurality of placement holes opened on the annular plate, a base plate fixedly connected to the bottom surface of the circular shell, an inlet pipe and an outlet pipe disposed on the base plate, both the inlet pipe and the outlet pipe being fixedly fitted with one-way valves arranged in opposite directions, a first cover plate threadedly connected to the base plate, a second cover plate fixedly connected to the outer wall of the first cover plate, and a sealing component disposed on the first cover plate.

[0007] In some embodiments, the positioning component includes side holes, and two side holes are symmetrically opened on the annular plate. A movable rod is movably connected in each side hole. The movable rod is concave and a first spring is sleeved on the side wall of the inner cavity of the side hole. A positioning plate is fixedly connected to the end of the movable rod away from the first spring, and a vertical groove extends from one side of the movable rod.

[0008] In some embodiments, the sealing assembly includes baffles, two of which are symmetrically arranged at the inlet pipe, and side plates are fixedly connected to the side walls of the baffles. A round shaft is fixedly connected to the side plates, and flat plates are movably connected to both ends of the round shaft. The flat plates are fixedly connected to a first cover plate, and a second spring is sleeved on the round shaft. The two ends of the second spring are fixedly connected to the flat plate and the side plates, respectively.

[0009] In some embodiments, the opening of the second cover plate is downward, and the inner diameter of the second cover plate is the same as the outer diameter of the movable shell. The inner wall of the second cover plate and the outer wall of the movable shell are provided with matching threads.

[0010] In some embodiments, anti-slip pads are fixedly connected to the inner walls of the placement holes, and the anti-slip pads are arranged in a ring shape.

[0011] In some embodiments, two slide rails are symmetrically fixedly connected to the outer side wall of the circular shell, and a slide groove is provided on the inner side wall of the annular plate, with the slide rails and the slide groove being movably connected.

[0012] In some embodiments, a handle is fixedly connected to the top surface of the movable shell.

[0013] With the above solution, when carrying this bottle-mouth dispensing controller, the inlet and outlet pipes are removed from the base plate. Then, the movable shell is pushed to expose the annular plate. The operator can insert the inlet and outlet pipes into the placement holes respectively. The anti-slip pads secure the inlet and outlet pipes. The movable shell is then pushed to place the inlet and outlet pipes between the round shell and the movable shell. This not only facilitates carrying the inlet and outlet pipes but also reduces external environmental contamination, improving portability. After placing the inlet and outlet pipes, the first and second cover plates are unscrewed from the base plate. At this time, under the elastic force of the second spring, the side plates on both sides move the baffles, using the two baffles to close the opening at the inlet pipe. Then, the second cover plate is reversed, so that the second cover plate is threadedly connected to the movable shell, thus limiting the movable shell and closing the inlet pipe. This effectively reduces the entry of external impurities and the inconvenience caused by the movement of the movable shell, improving portability.

[0023] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figure 1-5As shown, this application embodiment provides a portable bottle mouth liquid dispensing controller, including a circular shell 1, a piston 2 disposed inside the circular shell 1, a fixed rod 3 fixedly connected to the center of the top surface of the piston 2, the top end of the fixed rod 3 penetrating the circular shell 1 and fixedly connected to a movable shell 4, a vertical groove 5 opened on the movable shell 4 and a scale 6 fixedly connected thereto, an annular plate 7 movably connected between the movable shell 4 and the circular shell 1, a positioning component 8 disposed on the annular plate 7, the positioning component 8 including a side hole 17, two side holes 17 symmetrically opened on the annular plate 7, a movable rod 18 movably connected in each side hole 17, the movable rod 18 is concave, and a first spring 19 is sleeved on the side wall of the movable rod 18 located in the inner cavity of the side hole 17, a positioning plate 20 is fixedly connected to the end of the movable rod 18 away from the first spring 19, and a vertical groove 5 extends out from one side of the movable rod 18; In the technical solution of this embodiment, during use, by pulling the movable rod 18, the first spring 19 is compressed and the positioning plate 20 is separated from the outer wall of the circular shell 1. At this time, the height of the annular plate 7 can be adjusted based on the scale 6. Then, by releasing the movable rod 18, the positioning plate 20 is pressed against the outer wall of the circular shell 1 under the elastic force of the first spring 19, so that the height of the movable shell 4 can be controlled, thereby limiting the height of the piston 2. In this way, the liquid separation operation of a specified amount of solution can be completed. A handle 29 is fixedly connected to the top surface of the movable shell 4 for easy carrying and operation of the controller; Furthermore, the annular plate 7 is provided with several placement holes 9, and a base plate 10 is fixedly connected to the bottom surface of the round shell 1. An inlet pipe 11 and an outlet pipe 12 are provided on the base plate 10. One-way valves 13 arranged in opposite directions are fixed to both the inlet pipe 11 and the outlet pipe 12. Anti-slip pads 26 are fixedly connected to the inner wall of the placement holes 9. The anti-slip pads 26 are arranged in an annular shape. In the technical solution of this embodiment, when carrying the bottle mouth liquid dispensing controller, the inlet pipe 11 and the outlet pipe 12 are removed from the base plate 10, and then the movable shell 4 is pushed to expose the annular plate 7. The operator can insert the inlet pipe 11 and the outlet pipe 12 into the placement hole 9 respectively. The inlet pipe 11 and the outlet pipe 12 are fixed by the anti-slip pad 26. Then, the inlet pipe 11 and the outlet pipe 12 are placed between the round shell 1 and the movable shell 4 by pushing the movable shell 4. This not only makes it easier to carry the inlet pipe 11 and the outlet pipe 12, but also reduces the pollution of the external environment and improves portability. Furthermore, two slide rails 27 are symmetrically fixedly connected to the outer side wall of the circular shell 1, and a slide groove 28 is provided on the inner side wall of the annular plate 7. The slide rails 27 and the slide groove 28 are movably connected, which allows the annular plate 7 to move stably on the outer wall of the circular shell 1, facilitating precise control of the liquid distribution volume. A first cover plate 14 is threaded onto the base plate 10. A second cover plate 15 is fixedly connected to the outer wall of the first cover plate 14. The opening of the second cover plate 15 faces downward, and the inner diameter of the second cover plate 15 is the same as the outer diameter of the movable shell 4. The inner wall of the second cover plate 15 and the outer wall of the movable shell 4 are provided with matching threads. A sealing component 16 is provided on the first cover plate 14. The sealing component 16 includes a baffle 21. Two baffles 21 are symmetrically arranged at the liquid inlet pipe 11. A side plate 22 is fixedly connected to the side wall of the baffle 21. A round shaft 23 is fixedly connected to the side plate 22. A flat plate 24 is movably connected to both ends of the round shaft 23. The flat plate 24 is fixedly connected to the first cover plate 14. A second spring 25 is sleeved on the round shaft 23. The two ends of the second spring 25 are fixedly connected to the flat plate 24 and the side plate 22, respectively. In the technical solution of this embodiment, after the inlet pipe 11 and outlet pipe 12 are placed, the first cover plate 14 and the second cover plate 15 are unscrewed from the base plate 10. At this time, under the elastic force of the second spring 25, the side plates 22 on both sides can drive the baffles 21 to move. The two baffles 21 are used to close the opening at the inlet pipe 11. Then, the second cover plate 15 is reversed so that the second cover plate 15 is threadedly connected to the movable shell 4. This can limit the movable shell 4 and close the inlet pipe 11, which can effectively reduce the entry of external impurities and the inconvenience caused by the movement of the movable shell 4, and improve portability.
