The first valve seat 121 is formed with a first through hole 1211, the first valve nozzle 122 is substantially flat and hollow, the first connecting post 123 is substantially hollow and tubular, the pressure channel 124 is formed by an inner cavity of the first connecting post 123, and the first valve nozzle 122 and the first connecting post 123 are both disposed corresponding to the first through hole 1211, such that the inner cavity of the first valve nozzle 122 is communicated with the pressure channel 124 through the first through hole 1211. The first valve nozzle 122 includes a first surface 122A, a second surface 122B, a third surface 122C, a fourth surface 122D, and a fifth surface 122F, wherein the first surface 122A and the second surface 122B are disposed oppositely, the third surface 122C and the fourth surface 122D are disposed oppositely, the first surface 122A, the third surface 122C, the second surface 122B, and the fourth surface 122D are sequentially connected to form a cylinder, and the fifth surface 122F is connected to the first surface 122A, the second surface 122B, the third surface 122C, and the fourth surface 122D.

When pressurized fluid is input into first valve nozzle 122 through pressure passage 124, the increase in pressure within the interior chamber of first valve nozzle 122 deforms first valve nozzle 122 to open first passage 1221, thereby allowing pressurized fluid to be input into reservoir 110 and increasing the pressure within reservoir 110. It should be noted that, because the third surface 122C and the fourth surface 122D of the first valve nozzle 122 are both inclined surfaces, the thickness of the first valve nozzle 122 in the direction from the third surface 122C to the fourth surface 122D is reduced, which is beneficial to the outward expansion and deformation of the third surface 122C and the fourth surface 122D of the first valve nozzle 122, and is convenient for the first passage 1221 to be pushed open, so as to input the pressurized fluid into the reservoir 110.
