[0005] Further, a sleeve is fixed in the right end of the head cap, the rear end of the sealing pad has a sliding column, the sliding column is inserted into the sleeve and is in forward and backward sliding cooperation with the sleeve, a spring is sleeved on the sleeve, and the spring is clamped between the sealing pad and the inner wall of the head cap.

[0006] Further, the front end surface of the sealing pad is used for plugging the rear end opening of the liquid outlet channel.

[0007] Further, an upper cover is fixed on the upper end of the bottle body, the upper cover has a waist hole extending forward and backward and upward and downward, the head cap has a liquid outlet pipe at the upper end, the liquid outlet channel is located inside the liquid outlet pipe, the liquid outlet is located at the front end of the liquid outlet channel, and the front end of the liquid outlet pipe penetrates through the waist hole.

[0008] The cosmetic bottle provided by the present application has the following beneficial effects: during work, the liquid is drawn out of the bottle body and flows into the liquid inlet channel, and then enters the buffer channel, the liquid in the buffer channel pushes the sealing pad to move backward, the rear end opening of the liquid outlet channel is opened, the spring is compressed, after stopping work, the sealing pad moves forward rapidly to plug the rear end opening of the liquid outlet channel under the elastic force of the spring, and the liquid cannot enter the liquid outlet channel, thereby achieving the effect of preventing liquid dripping.

Embodiment

[0013] In order to more intuitively and completely understand the technical solutions of the present application, the following non-limiting characteristic descriptions are now made in conjunction with the drawings of the present application:

[0014] As shown in Figure 1 - Figure 3 A cosmetic bottle, comprising a bottle body 1, the upper end of the bottle body 1 is provided with a pump head, the pump head comprises a pump body 2, a head cap 3 connected with the pump body 2, and a pressure cap 4 connected with the head cap 3, the head cap 3 has a liquid outlet 4111 at the front end, the head cap 3 has a liquid inlet channel 42 extending upward and downward at the lower end, the head cap 3 has a liquid outlet channel 411 extending forward and backward at the upper end, the rear end of the liquid outlet channel 411 is communicated with a buffer channel 43 extending left and right, the upper end of the liquid inlet channel 42 is communicated with the buffer channel 43, a sealing pad 5 for opening or closing the rear end opening of the liquid outlet channel 411 is installed in the right end of the head cap 3 and can move forward and backward, and the sealing pad 5 is located behind the buffer channel 43.

[0015] As shown in Figure 3 , a sleeve 6 is fixed in the right end of the head cap 3, the rear end of the sealing pad 5 has a slide column 61, the slide column 61 is inserted into the sleeve 6 and is in forward and backward sliding cooperation with the sleeve 6, a spring 7 is sleeved outside the sleeve 6, and the spring 7 is clamped between the sealing pad 5 and the inner wall of the head cap 3. The front end surface of the sealing pad 5 is used to block the rear end opening of the liquid outlet channel 411. The spring 7 provides power to the sealing pad 5, so that the sealing pad 5 can tightly block the rear end opening of the liquid outlet channel 411.

[0016] As shown in Figure 1 and Figure 2 ​As shown, the upper end of the bottle body 1 is fixed with an upper cover 8 by threaded connection, the upper cover 8 is provided with a waist hole 81 extending through front and back and up and down, the head cap 3 is provided with a liquid outlet pipe 41, the liquid outlet channel 411 is located inside the liquid outlet pipe 41, the liquid outlet 4111 is located at the front end of the liquid outlet channel 411, and the front end of the liquid outlet pipe 41 penetrates the waist hole 81. The waist hole 81 is used to limit the stroke of the head cap 3, and the upper cover 8 with different lengths of the waist hole 81 can be set according to different consumers during production, so as to facilitate the use of different consumers.

[0017] During work, the liquid is drawn out from the bottle body 1 and flows to the liquid inlet channel 42, and then enters the buffer channel 43. The liquid in the buffer channel 43 pushes the sealing gasket 5 to move backward, so that the rear end opening of the liquid outlet channel 411 is opened, and the spring 7 is compressed. After stopping working, the sealing gasket 5 is quickly moved forward to block the rear end opening of the liquid outlet channel 411 by the elastic force of the spring 7, so that the liquid cannot enter the liquid outlet channel 411, and the anti-dripping effect can be achieved.

[0018] Of course, the above is only a preferred embodiment of the present application, and is not limited to the patent scope of the present application. Any simple modification and equivalent structural change according to the content of the specification and drawings should also be included in the patent protection scope of the present application.
