Description

Technical Field

[0001] This utility model relates to the field of emulsion pump head technology, and in particular to a drip-proof press-type emulsion pump head. Background Technology

[0002] A lotion pump head is a common liquid packaging accessory, mainly used in bottled containers of cosmetics and skincare products (such as lotions, serums, and shower gels). It dispenses a measured amount of product by pressing. It consists of a pump head, a cap, a bottle cap, a piston rod, an upper ball valve, a lower ball valve, a spring, a storage container, and a straw. Its working principle is that when pressed, the spring is compressed to generate negative pressure, drawing the liquid from the bottle into the pump chamber through the straw; when released, the spring returns to its original position, pushing the piston and squeezing the liquid out of the outlet.

[0003] Traditional emulsion pump heads often cause emulsion to accumulate and drip at the outlet after pressing, and are prone to clumping, leading to blockages and waste. Furthermore, traditional emulsion pump heads are inconvenient to control the amount dispensed in a single press, requiring users to rely on their experience to judge the amount to be dispensed, which can also lead to unnecessary waste. Therefore, a drip-proof press-type emulsion pump head is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a drip-proof press-type emulsion pump head to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drip-proof press-type emulsion pump head, comprising a pump head, a cap, a bottle cap, a storage container, and a straw. The pump head is provided with an outlet pipe, the end of which away from the pump head is closed and has a spring. A stopper is provided on the spring and is slidably connected inside the outlet pipe. An outlet hole is provided on the outer wall of the outlet pipe, located at the spring. The outer wall of the cap is threaded and threaded with a cap, which is arranged below the pump head.

[0006] Preferably, the liquid outlet is located at the bottom end of the liquid outlet pipe.

[0007] Preferably, the outlet tube has a conical hole, and the end of the plug away from the spring is a cone and fits into the conical hole.

[0008] Preferably, the end of the plug near the spring is a column, and a sealing ring is embedded in the outer wall, with the outer wall of the sealing ring and the inner wall of the liquid outlet pipe being sealed together.

[0009] Preferably, the connection between the cap and the bottle cap is radially extended, and a collar is provided on the extended part. An annular groove is provided on the bottom end of the cap, and the collar is arranged in the annular groove.

[0010] Preferably, rubber rings are embedded in both the inner and outer walls of the collar end, and the two rubber rings are in contact with the inner walls of the two sides of the annular groove, respectively.

[0011] Preferably, the outer wall of the pressure cap is provided with anti-slip grooves distributed axially in a circular pattern.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the closed end of the outlet tube and the cooperation between the spring and the stopper allow the emulsion to flow in the outlet tube with thrust during each press of the emulsion pump head. This thrust acts on the stopper, pushing the spring to compress. When the stopper moves to the outlet hole, the emulsion can flow out. After pressing stops, the emulsion stops flowing, the spring returns to its original compression, and the emulsion level is pushed away from the outlet hole, effectively preventing dripping and waste caused by emulsion clumping at the outlet.

[0014] In this invention, the threaded connection between the pressure cap and the pressure cap allows for adjustment of the top height of the pressure cap, thereby providing support and limiting for the bottom of the pump head. This enables the emulsion pump head to adjust the amount dispensed per press according to the user's needs, avoiding unnecessary waste. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A drip-proof press-type emulsion pump head includes a pump head 1, a cap 2, a bottle cap 3, a storage container 4, and a straw 5. The pump head 1 is provided with an outlet pipe 6, the end of the outlet pipe 6 away from the pump head 1 is closed and is provided with a spring 7. A stopper 8 is provided on the spring 7 and is slidably connected inside the outlet pipe 6. An outlet hole 9 is opened on the outer wall of the outlet pipe 6 and is located at the spring 7. The outer wall of the cap 2 is threaded and is threadedly connected with a cap 10, which is arranged below the pump head 1.

[0022] When using this emulsion pump head, pressing the pump head 1 compresses its internal elastic element, creating negative pressure. This draws the liquid from the emulsion bottle into the storage container 4 through the straw 5. Continuing to press the pump head causes the liquid level in the storage container 4 to gradually rise until it passes through the pump head 1 and flows into the outlet pipe 6. The thrust generated by the liquid flowing in the outlet pipe 6 acts on the stopper 8, causing it to move and compressing the spring 7. After the stopper 8 has moved a certain distance, the liquid aligns with the outlet hole 9, allowing the liquid to be discharged from the outlet hole 9. Stopping the pressing of the pump head 1 stops the liquid flow in the outlet pipe 6, the stopper 8 loses its thrust, and the spring 7 returns to its original position. The moving stopper 8 moves in the opposite direction, pushing the liquid back and moving it away from the outlet hole 9. At this point, the liquid discharge from the outlet hole 9 stops, and the elastic force of the spring 7 keeps the stopper 8 pushing the liquid, thus effectively preventing the liquid from dripping at the outlet hole 9 and preventing waste caused by clumping at the outlet. The pressure cap 10 is threaded onto the pressure cap 2, allowing the height of the top of the pressure cap 10 to be adjusted, thus providing support and limiting the bottom of the pump head 1. This allows the emulsion pump head to adjust the amount dispensed per press according to the user's needs, avoiding unnecessary waste.

[0023] Specifically, in this embodiment, the liquid outlet 9 is arranged at the bottom end of the liquid outlet pipe 6 to avoid the splashing problem that occurs when liquid is discharged when the liquid outlet 9 is at the end.

[0024] Specifically, in this embodiment, a conical hole 11 is provided in the liquid outlet pipe 6, and the end of the plug block 8 away from the spring 7 is a cone and is adapted to fit in the conical hole 11, which improves the sealing effect of the plug block 8.

[0025] Specifically, in this embodiment, the end of the plug 8 near the spring 7 is a column, and a sealing ring 12 is embedded in the outer wall. The outer wall of the sealing ring 12 is sealed to the inner wall of the liquid outlet pipe 6, which improves the sealing effect between the plug 8 and the liquid outlet pipe 6, prevents liquid from seeping into the space of the spring 7, and avoids the plug 8 from being obstructed from moving.

[0026] Specifically, in this embodiment, the connection between the cap 2 and the bottle cap 3 extends radially, and a collar 13 is provided on the extended part. An annular groove 14 is provided on the bottom end of the cap 10, and the collar 13 is arranged in the annular groove 14. The fit between the collar 13 and the annular groove 14 provides stability for the threaded connection of the cap 10 and prevents shaking.

[0027] Specifically, in this embodiment, rubber rings 15 are embedded in both the inner and outer walls of the end of the collar 13. The two rubber rings 15 are in contact with the inner walls of the two sides of the annular groove 14 respectively. The rubber rings 15 increase the resistance to movement between the pressure cap 10 and the pressure cover 2, thereby improving the effect of maintaining the height state of the pressure cap 10 after adjustment.

[0028] Specifically, in this embodiment, the outer wall of the pressure cap 10 is provided with anti-slip grooves 16 distributed axially in a circular pattern to prevent slippage when the pressure cap 10 is manually rotated.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
