Example (b): a structure of a cleansing oil nozzle comprises a rotary cover 1 connected with a cleansing oil bottle, wherein the bottom of the inner side of the rotary cover 1 is pressed against a flange of a cylinder 2 and is lined with a gasket 3 to be fixed at the opening of the cleansing oil bottle. A gland 6 with a sandwich structure of an inner layer 4 and an outer layer 5 at the lower end is arranged, and the sandwich is in sliding fit with the top of the screw cap 1; a counter bore is arranged in the gland 6, a shoulder 7 is arranged in the counter bore, the upper end of a connecting rod 8 is tightly matched with the counter bore in the gland 6 and is positioned by the shoulder 7 in the counter bore; the upper end of the connecting rod 8 is provided with an upper counter bore 9, the lower end of the connecting rod 8 is provided with a lower counter bore 10, and the upper counter bore 9 is communicated with the lower counter bore 10 through a through hole in the middle of a step 11 in the middle of the connecting rod 8; an inner bushing 12 is arranged between the connecting rod 8 and the rotary cover 1, the connecting rod 8 is in sliding fit with the inner bushing 12, the lower end face of the inner layer of the gland 6 corresponds to the upper end face of the inner bushing 12, and the lower end face is used as the limiting position of the action of the gland 6; the lower end face of the connecting rod 8 is pressed against a piston connecting ring 14 on the upper end face of the piston 13, the piston 13 is movably matched with the cylinder 2, a needle valve 15 is matched with a sinking hole 10 of the connecting rod 8 and an inner hole of the piston 13, the lower end part of the needle valve 15 is of a hemispherical structure, the back face of the hemispherical structure is provided with an annular groove 16 which is pressed against the lower end face of the piston 13, the inner surface of the hemispherical structure presses against a return spring 17, the lower end of the return spring 17 presses against a steel ball 18, and the steel ball 18 is separably in sealing fit with a valve seat 19 arranged in the middle of the cylinder 2; the upper end surface of the needle valve 15 is limited by taking a step 11 at the bottom of a sinking hole 10 of the connecting rod 8 as action; the nozzle 20 and the gland 6 are of an integrated structure, the nozzle 20 is of a tubular structure, an inner channel of the nozzle 20 is communicated with a counter bore 9 on the connecting rod 8, a nozzle 21 is arranged at the front end of the nozzle 20, the nozzle 21 is slightly inclined downwards, and an angle of 70 degrees is formed between an axis 22 of the nozzle and an axis 23 of the cylinder. See fig. 1.

The piston 13 is made of rubber material. The return spring 17 is a high-strength stainless steel cylindrical helical compression spring.

The top of spiral cover 1 is provided with detachable card neck 24, and card 24 is the elastic construction of opening ring type, and back contact on terminal surface and the spiral cover 1 under card neck 24, terminal surface contact under card neck 24 up end and the skin of gland 6. The neck 24 is arranged to lock the gland 6.

The screw cap 1 is screwed or buckled on the container bottle mouth, the gland 6 can move up and down relative to the screw cap 1, and the cylinder 2 extends into the container bottle mouth. In the transportation process, the neck 24 is buckled on the screw cap 1 to limit the pressing cover 6, so that the contents in the bottle are prevented from being sprayed out accidentally. When in use, the neck 24 is taken down and the pressing cover 6 is pressed down. The bottom of the cylinder 2 is provided with a steel ball 18, and the steel ball 18 is positioned at the connecting port of the bottom of the cylinder 2 and a suction pipe 25 extending to the bottom of the container. When the gland 6 is pressed for the first time, the gland 6 drives the connecting rod 8 and the piston 13 to move downwards, the steel ball 18 always seals the valve seat at the inlet of the bottom of the cylinder 2 under the pressure, and air in the cylinder 2 is extruded to pass through a gap between the needle valve 15 and the piston 13 to the middle of the connecting rod 8, and then the through hole of the step 11 is discharged outwards through the nozzle 21. At the moment of releasing the gland 6, the restoring force of the return spring 17 pushes the connecting rod 8 through the needle valve 15 and the piston 13, the connecting rod 8 drives the gland 6, the piston 13 and the gland 6 move upwards, the volume in the cylinder 2 is promoted to expand rapidly, negative pressure is generated in the cylinder 2, and fluid in the container is sucked into the cylinder 2. The gland 6 is pressed several times repeatedly until the cylinder 2 is filled with fluid. After the cylinder 2 is filled with the fluid, the gland 6 is pressed down again, so that the fluid can be extruded, and the action principle is as follows: pressing down on the gland 6, the compressive force will open the gap between the lower edge of the piston 13 and the needle valve 15, and the fluid will enter the central hole channel of the connecting rod 8 from the gap between them and then be ejected from the flow channel of the gland 6. When the gland 6 is released, the connecting rod 8 moves upwards under the action of the return spring 17, the lower edge of the piston 13 is tightly closed with the needle valve 15 which is lifted upwards, and simultaneously, the fluid in the container is pumped into the cylinder 2 again due to the expansion of the volume in the cylinder 2, and the repeated action can be used repeatedly.

The contact of the lower end of the connecting rod of the device and the piston connecting ring and the penetration of the lower end of the piston into the needle valve annular groove are always in an asynchronous state, when the gland is released, the convex ring of the needle valve annular groove and the lower end of the piston are instantly sealed to isolate a flow passage and an air cylinder, and meanwhile, the connecting rod rises to enable the volume of the flow passage to be instantly expanded, negative pressure fluid is generated to be sucked back, and dripping leakage is avoided.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
