Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0048] Embodiment 1:

[0049] like Figure 1-6 As shown, this embodiment provides a cosmetic liquid dispensing head for preventing stored liquid from overflowing, comprising: a liquid delivery tube 1 and a liquid dispensing device 2;

[0050] The liquid outlet device 2 specifically includes a liquid outlet lock 21, a liquid outlet pipe 22, and a liquid outlet cover 23; the liquid outlet lock 21 is arranged at the bottom of the liquid outlet pipe 22; the liquid outlet cover 23 is provided with a cover opening 231 for the liquid outlet pipe 22 to pass through; an extrusion protrusion 222 is provided on the outer wall of the liquid outlet 221 of the liquid outlet pipe 22;

[0051] When the locked state is converted to the unlocked state, the liquid outlet pipe 22 moves toward the cover opening 231, driving the liquid outlet lock 21 away from the liquid medicine transmission pipe 1, so that the liquid medicine in the liquid medicine transmission pipe 1 is transmitted to the liquid outlet pipe 22;

[0052] When the unlocked state is converted to the locked state, the liquid outlet pipe 22 moves away from the cover opening 231, driving the liquid outlet lock 21 to approach and block the liquid medicine transmission pipe 1, and causing the cover opening 231 to squeeze the squeezing protrusion 222 to shrink the liquid outlet 221.

[0053] In the traditional cosmetic liquid extraction process, there is often a problem of liquid accumulation in the tube, that is, after the cosmetic liquid is discharged through a pressure pump, some of the liquid will remain in the tube mouth and will not be discharged. And these liquids may flow out of the tube mouth during use, thus causing pollution.

[0054] Therefore, in this embodiment, in the initial state, i.e., the locked state, the liquid outlet lock 21 is plugged into the liquid outlet hole in the liquid medicine transmission tube 1, thereby blocking the liquid outlet hole, so that two isolated spaces are formed between the liquid medicine transmission tube 1 and the liquid outlet tube 22, thereby preventing the liquid in the liquid medicine transmission tube 1 from flowing into the liquid outlet tube 22;

[0055] When it is needed, the liquid outlet pipe 22 is moved outward, that is, away from the liquid outlet hole, so that the liquid outlet lock 21 is removed from the liquid outlet hole, so that the liquid outlet pipe 22 and the liquid medicine transmission pipe 1 are connected, so that the liquid medicine flows from the liquid medicine transmission pipe 1 into the liquid outlet pipe 22, so as to output the liquid medicine;

[0056] When use is completed, the liquid outlet pipe 22 is moved inward, that is, toward the direction close to the liquid outlet hole, so that the liquid outlet lock 21 is plugged into the liquid outlet hole, thereby blocking the liquid outlet hole, isolating the liquid medicine transmission pipe 1 and the liquid outlet pipe 22, and preventing the liquid outlet pipe 22 from further outputting the liquid medicine. However, at this time, part of the liquid medicine is retained in the liquid outlet pipe 22. At the same time, when the liquid outlet pipe 22 is recovered, the cover port 231 will squeeze the squeezing protrusion 222 provided at the liquid outlet port 221 of the liquid outlet pipe 22 to shrink the liquid outlet port 221, thereby preventing the part of the liquid medicine retained in the liquid outlet pipe 22 from overflowing.

[0057] In this embodiment, the extrusion protrusion 222 is provided at the liquid outlet 221 of the liquid outlet pipe 22. When the liquid outlet pipe 22 is recovered, the extrusion protrusion 222 is squeezed through the cover opening 231, thereby shrinking the liquid outlet 221, thereby preventing the liquid medicine remaining in the liquid outlet pipe 22 from overflowing.

[0058] like Figure 2 As shown, preferably, a shape fixing ring 225 is provided behind the extrusion protrusion 222 along the direction of the liquid outlet pipe 22 toward the liquid outlet 221 .

[0059] At the same time, in order to prevent the extrusion protrusion 222 from being deformed and unable to recover after being squeezed, a shape fixing ring 225 is provided behind the extrusion protrusion 222 along the direction of the liquid outlet tube 22 toward the liquid outlet 221. Generally, a hard material is used. Through this hard material, the extrusion protrusion 222 can still restore the original shape of the liquid outlet tube 22 under the action of the shape fixing ring 225 after being squeezed.

The liquid outlet cover 23 is provided with an inner cover screw thread 232; the liquid outlet pipe 22 is provided with a liquid outlet screw thread 223 corresponding to the inner cover screw thread 232; the liquid outlet pipe 22 is rotatably connected to the liquid outlet cover 23 through the inner cover screw thread 232 and the liquid outlet screw thread 223.

[0062] In this embodiment, in the specific control method of the liquid outlet pipe 22, the position of the liquid outlet pipe 22 is controlled by rotating the liquid outlet cover 23. More specifically, an inner cover screw thread 232 is provided on the inner side of the liquid outlet cover 23, and a liquid outlet screw thread 223 corresponding to the inner cover screw thread 232 is provided on the outside of the liquid outlet pipe 22, so that when the liquid outlet cover 23 rotates, the liquid outlet pipe 22 can be driven to rotate, thereby being driven to move in the direction of the cover opening 231 or in the opposite direction thereof.

[0063] Meanwhile, in order to realize the rotation of the liquid outlet cover 23, the liquid outlet cover 23 is used as a rotor and the container connecting cover 3 is used as a stator. A corresponding cover body rotating track 31 is provided on the container connecting cover 3 for the liquid outlet cover 23 to rotate thereon.

[0064] Further preferably, a liquid outlet hood opening 32 is provided on the container connecting hood 3, the liquid medicine transmission tube 1 extends out along the liquid outlet hood opening 32 and is connected to the liquid outlet pipe 22 in the liquid outlet hood opening 32; when the locked state is converted to the unlocked state, the liquid outlet hood 23 rotates in the unlocking direction to drive the liquid outlet pipe 22 to move toward the hood opening 231; when the unlocked state is converted to the locked state, the liquid outlet hood 23 rotates in the locking direction to drive the liquid outlet pipe 22 to move in the opposite direction to the hood opening 231.

[0065] In this embodiment, the position of the liquid outlet pipe 22 is controlled by the cooperation between the inner cover screw thread 232 and the liquid outlet screw thread 223, which is easy to use and has strong mechanical reliability.

When the unlocking end 233 arranged in the liquid outlet cover 23 is generally arranged in a step shape, when the limiting wing 224 moves to the position of the unlocking end 233, it will be blocked by the step-shaped unlocking end 233, thereby limiting the movement of the limiting wing 224 in this direction.

[0069] The drug liquid transmission tube 1 includes a barrel interface 11 and an infusion hose 12; an infusion port 111 is provided at the bottom of the barrel interface 11, and the infusion hose 12 is connected to the infusion port 111; when in the locked state, the liquid outlet lock 21 blocks the infusion port 111.
