Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, in particular to a brake fluid filler. Background Art

[0002] Brake fluid, also known as brake fluid or brake oil, is the hydraulic medium of the automobile braking system. Because liquid cannot be compressed, the pressure output from the master cylinder will be directly transmitted to the slave cylinder through the brake fluid. It has four major functions: energy transmission, heat dissipation, corrosion and rust prevention, and lubrication. Usually, cars need to replace brake fluid regularly to ensure the normal use of the car.

[0003] However, since the current brake fluid replacement device is relatively troublesome to use, it usually requires professional operators to use it, and it is difficult for ordinary users to replace it when they need to. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a brake fluid filler to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a brake fluid filler, comprising a filling pipe and a liquid storage tank, wherein an air intake pipe is installed at the upper end of the filling pipe, an exhaust pipe is arranged at the lower end of the filling pipe located above the liquid storage tank, valve cores are installed inside the air intake pipe and the exhaust pipe, and the valve core comprises a valve ball holder, a spring, and a valve ball; a liquid outlet pipe is installed at the lower end of the liquid storage tank, a corrugated hose is installed at one end of the liquid outlet pipe, a light strip is arranged on the outer side of the end of the corrugated hose, a push rod is arranged inside the filling pipe, and the end of the push rod is located inside the filling pipe and is connected with a piston head.

[0006] As a further solution of the utility model: an inner thread is provided on the inner side of the lower end of the exhaust pipe, a joint thread is provided on the outer side of the upper end of the liquid storage tank, and a control valve is provided on the outer side of the liquid outlet pipe.

[0007] As a further solution of the utility model: a piston baffle is installed on the inner side wall of the filling pipe at a side of the exhaust pipe close to the piston head, and scale lines are installed on the side surface of the filling pipe.

[0008] As a further solution of the utility model: the air intake pipe and the exhaust pipe are both arranged to penetrate the filling pipe, the valve ball is clamped with the valve ball holder, and the spring is fixedly connected to the valve ball.

[0009] As a further solution of the utility model: the corrugated hose and the liquid outlet pipe are arranged to penetrate each other.

[0010] As a further solution of the utility model: the liquid storage tank is fixedly connected by meshing the joint thread with the internal thread.

[0011] As a further solution of the present invention: the piston head is a rubber component.

[0012] As a further solution of the utility model: the piston baffle is fixedly connected to the filling pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The valve cores inside the intake pipe and the exhaust pipe are set in opposite directions, which can realize one-way exhaust and intake. The flow rate of each push is determined by the movement of the piston head inside the filling pipe and the movement position on the scale line, which is convenient for judging the amount of liquid added.

[0015] 2. After the corrugated hose is placed inside the brake fluid tank, the light emitted by the light strip can easily determine the liquid level inside the brake fluid tank, making it convenient for non-professionals to add brake fluid by themselves. BRIEF DESCRIPTION OF THE DRAWINGS
