[0026] This specific embodiment is a dual-material mixing press-type pump head, the structural schematic diagram of which is shown below. Figures 1-7 As shown, the pump head is mounted on the bottle body 21. The pump head includes a pump housing 1, a nozzle 2, an infusion tube 3, and a cap 4 connected to the bottle body. An outer shell 5 is fixedly connected to the outside of the pump housing 1. The infusion tube 3 includes a main tube 6 and an auxiliary tube 7. An upper one-way valve assembly 8 and a lower one-way valve assembly 9 are respectively installed inside the main tube 6 and the auxiliary tube 7. The top end of the main tube 6 is connected to the nozzle 2. The top end of the auxiliary tube 7 is located inside the pump housing 1 and is fixedly connected to a limit block 10. A plug 11 is fixedly connected to the outer surface of the auxiliary tube 7. The plug 11 is used to seal the gap between the auxiliary tube 7 and the outer shell 5 and form a receiving cavity 12. The top opening of the bottle body 21 is connected to the cap 4 by a threaded seal. The bottle body 21 stores a first liquid. The plug 11 is sealed and fixed to the bottom end of the outer shell 5 so that the receiving cavity 12 stores a second liquid, thereby storing the two liquids separately and preventing the two liquids from mixing before use.

[0027] like Figure 2 and Figure 3As shown: In this embodiment, the outer shell 5 is annularly sleeved on the outer surface of the pump housing 1 and is coaxially arranged with the pump housing 1. The inner wall of the top end of the outer shell 5 is fixedly connected to the outer surface of the pump housing 1. The bottom end of the outer shell 5 extends downward to form a sealed receiving cavity 12 with the auxiliary pipe 7.

[0028] like Figure 3 and Figure 4 As shown: In this embodiment, a lower mounting sleeve 101 is fixedly connected to the inner top of the pump housing 1, an upper mounting sleeve 102 is fixedly connected to the outer surface of the main pipe 6, a spring 103 is installed between the lower mounting sleeve 101 and the upper mounting sleeve 102, and the bottom end of the main pipe 6 passes through the lower mounting sleeve 101 and slides and seals with the lower mounting sleeve 101.

[0029] The upper mounting sleeve 102 can be used to divide the inside of the pump housing 1 into two parts, sealing and fixing it to prevent liquid from overflowing from the gap between the main pipe 6 of the pump housing 1, and also to facilitate the fixed installation of the spring 103.

[0030] like Figure 4 and Figure 5 As shown: In this embodiment, the upper one-way valve assembly 8 includes a secondary column 801 snapped and fixed to the bottom end of the main pipe 6. A plug column 802 is fixedly connected to the bottom end of the secondary column 801. An inlet channel 803 communicating with the main pipe 6 is opened between the side of the secondary column 801 and the plug column 802. A piston 804 is slidably sleeved on the outer surface of the bottom end of the main pipe 6 and a limiting platform 805 corresponding to the upper surface of the piston 804 is fixedly connected. A protrusion 806 corresponding to the lower surface of the piston 804 is fixedly connected to the outer side of the plug column 802. The outer surface of the piston 804 slides and seals with the inner wall of the pump housing 1.

[0031] When in use, piston 804 forms a seal with the inner wall of pump housing 1, which can control the pressure in the chamber of pump housing 1 so as to facilitate the intake and discharge of liquid. When the nozzle 2 is reset, it drives the main pipe 6, the auxiliary column 801 and the plug column 802 to move upward. At this time, during the upward movement of the plug column 802, the protrusion 806 can contact and seal with the lower surface of piston 804, and drive piston 804 to move upward.

[0032] like Figure 4 and Figure 5 As shown: In this embodiment, an upper limit ring 104 and a lower limit ring 105 are fixedly connected inside the bottom end of the pump casing 1. The limiting block 10 is located between the upper limit ring 104 and the lower limit ring 105. The upper surface of the limiting block 10 is provided with a receiving surface 106 corresponding to the plug 802. In this way, the limiting block 10 can only move between the upper limit ring 104 and the lower limit ring 105 to avoid separation. When the plug 802 moves downward, it can contact the receiving surface 106, driving the limiting block 10 to move to the lower limit ring 105. At this time, the plug cover 11 is opened.

[0033] like Figure 4 and Figure 6 As shown: In this embodiment, the outer surface of the plug 11 is provided with an annular groove 1101, and the inner bottom wall of the outer shell 5 is fixedly connected with a retaining ring 1102 corresponding to the groove 1101. The upper surface edge of the plug 11 is fixedly connected with multiple guide posts 1103. In this way, the plug 11 can be installed in the gap between the auxiliary pipe 7 and the outer shell 5. At this time, the groove 1101 is located in the retaining ring 1102, which not only performs preliminary positioning, but also provides effective sealing.

[0034] like Figure 4 and Figure 6 As shown: In this embodiment, the auxiliary pipe 7 includes an upper pipe 701 and a lower pipe 702. The plug 11 has a through hole 1104 in the middle. The upper pipe 701 and the lower pipe 702 are inserted and fixed at the upper and lower ends of the through hole 1104. The lower one-way valve assembly 9 includes a plug bead 901 and a limit frame 902. The limit frame 902 is fixedly connected inside the through hole 1104, and the plug bead 901 is located inside the limit frame 902. In this way, when the piston 804 moves downward, the plug bead 901 can block the through hole 1104. When the piston 804 moves upward, liquid can be drawn in from the through hole 1104.

[0035] Working principle: When in use, pressing the nozzle 2 moves the main pipe 6, the auxiliary column 801, and the plug 802 downward and compresses the spring 103. At this time, the plug 802 extends from the lower side of the piston 804 and exposes the liquid inlet channel 803 until the limiting platform 805 contacts the upper surface of the piston 804 and moves the piston 804 downward. At the same time, the plug 802 contacts the receiving surface 106 on the limiting block 10 and moves the limiting block 10 downward. During the downward movement, the limiting block 10 can move the upper pipe 701 and the plug 11 downward. Since the sealing force between the slot 1101 and the retaining ring 1102 on the plug 11 is small, the plug 11 can be opened by pressing the nozzle 2 downward. At this time, the second liquid stored in the receiving cavity 12 flows into the bottle body 21, thereby mixing the second liquid with the first liquid in the bottle body 21. Then, the nozzle 2 is released and reset under the elastic force of the spring 103.

[0036] After the two liquids are mixed, when the nozzle 2 is pressed again, the piston 804 can reduce the space inside the pump housing 1 as it moves downward. At this time, the pressure is increased, and the liquid is discharged from the pump housing 1 through this pressure, so that the mixed liquid in the bottle 21 can be squeezed out for use.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
