TECHNICAL FIELD
[0001] The utility model belongs to laundry liquid bottle technical field, concretely relates to a leakproof laundry liquid plastic bottle. BACKGROUND
[0002] In daily life, laundry liquid is an important part of household cleaning supplies, and its use frequency is very high. In the traditional laundry liquid container, the user measures the required amount of laundry liquid by pouring the laundry liquid into the bottle cap when using. Since the laundry liquid usually has strong fluidity, the laundry liquid residue is easily left on the outer wall of the bottle mouth, and the laundry liquid easily seeps out from the connection between the bottle cap and the bottle body to pollute the bottle body, which also causes waste of the laundry liquid. SUMMARY

[0005] The utility model has the advantages of:
[0006] The liquid inlet pipe and the flow guide plate arranged in the dosing box not only facilitate the quantitative extraction of the laundry liquid, but also effectively recover the residual laundry liquid on the piston through the inclined design of the flow guide plate and the arrangement of the backflow hole, thereby reducing the waste of the laundry liquid and environmental pollution.
[0007] The amount of laundry liquid poured out each time can be accurately controlled by rotating the screw rod and adjusting the position of the piston, which greatly improves the convenience and accuracy of use. At the same time, the design of the dosing box also makes the laundry liquid more stable during storage and transportation, thereby reducing the risk of leakage caused by shaking.
[0008] In order to scrape the liquid residue at the bottom end of the liquid outlet hole:
[0009] As a further improvement of the above technical solution: the top end edge of the liquid inlet pipe is arc-shaped.
[0010] The beneficial effect of the improvement is that when the laundry detergent flows out through the liquid outlet hole, the piston moves to the initial state, at which time the liquid adhering to the bottom end of the piston will be left at the end of the liquid outlet hole. When the dosing box is pulled out, the top end of the liquid inlet pipe will scrape the remaining liquid, which will flow along the arc-shaped surface to the top of the guide plate or back to the dosing cavity along the liquid inlet pipe.
[0011] In order to prevent the laundry detergent in the liquid storage cavity from leaking out:
[0012] As a further improvement of the above technical solution: the bottom end of the piston is slidingly attached to the inner wall of the liquid outlet hole.
[0013] The beneficial effect of the improvement is that the piston can block the liquid outlet hole to prevent the laundry detergent in the liquid storage cavity from leaking out.

[0016] The beneficial effect of the improvement is that by rotating the screw rod, the screw rod will slide up and down in the sleeve, and with the up and down movement of the screw rod, the limiting plate connected thereto will drive the movable rod to move up and down. The movement of the movable rod allows the piston to slide up and down in the liquid outlet hole. When the screw rod moves down to the limit position, the bottom end of the piston is separated from the liquid outlet hole, at which time the liquid in the liquid storage cavity flows out through the liquid outlet hole.
[0017] In order to flow the laundry detergent into the dosing cavity:
[0018] As a further improvement of the above technical solution: the inner diameter of the liquid inlet pipe is not less than the diameter of the bottom end of the piston, and the inner diameter of the liquid inlet pipe is not less than the inner diameter of the liquid outlet hole.

The user can observe the amount of liquid through the scale line window provided on the surface of the dosing cavity.
[0020] In order to store and limit the dosing box and the connecting plate:
[0021] As a further improvement of the above technical solution: the bottom end of the bottle body is threadedly connected to the screw rod one, and the end of the screw rod one is sleeved with a baffle, which extrudes the limiting connecting plate.
[0022] The beneficial effect of the improvement is that the connecting plate can be pulled out of the installation slot by rotating the screw rod to drive the baffle to be perpendicular to the ground, and the baffle does not press and limit the connecting plate, and the user can store and limit the quantitative box and the connecting plate by reverse operation.
[0023] In order to conveniently pour the laundry liquid supplement into the bottle body:
[0024] As a further improvement of the above technical scheme, the bottle body front side is provided with an observation window, and the liquid inlet pipe at the top side of the bottle body is threadedly connected with the bottle cap.
[0025] The beneficial effect of the improvement is that the user can conveniently pour the laundry liquid supplement into the bottle body by rotating the bottle cap to expose the liquid inlet pipe.
[0026] The parts not involved in the device are the same as or can be realized by the prior art. BRIEF DESCRIPTION OF DRAWINGS
