[0006] (2) Technical Solutions

[0007] To solve the above technical problems, the present invention provides such a dual-material mixing push-type pump head. The pump head is installed on the bottle body. The pump head includes a pump shell, a nozzle, an infusion tube, and a seal cover connected to the bottle body. An outer shell is fixedly connected to the outside of the pump shell. The infusion tube includes a main tube and an auxiliary tube. An upper one-way valve group and a lower one-way valve group are respectively installed inside the main tube and the auxiliary tube. The top end of the main tube is communicated with the nozzle. The top end of the auxiliary tube is located inside the pump shell and is fixedly connected with a limiting block. A plug cover is fixedly connected to the outer surface of the auxiliary tube. The plug cover is used to block the gap between the auxiliary tube and the outer shell and form a receiving cavity.

[0008] Preferably, the outer shell is annularly sleeved on the outer surface of the pump shell and is coaxially arranged with the pump shell. The inner wall of the top end of the outer shell is fixedly connected with the outer surface of the pump shell.

[0009] Further, a lower mounting sleeve is fixedly connected to the inner top of the pump shell. An upper mounting sleeve is fixedly connected to the outer surface of the main tube. A spring is installed between the lower mounting sleeve and the upper mounting sleeve. The bottom end of the main tube penetrates through the lower mounting sleeve and is slidably sealed with the lower mounting sleeve.

[0010] Furthermore, the upper one-way valve group includes a secondary column and a plug column fixedly connected to the bottom end of the main pipe. A liquid inlet channel communicating with the main pipe is formed between the side surface of the secondary column and the plug column. A piston is slidably sleeved on the outer surface of the bottom end of the main pipe, and a limiting platform corresponding to the upper surface of the piston is fixedly connected thereto. A convex block corresponding to the lower surface of the piston is fixedly connected to the outer side of the plug column. The outer surface of the piston is slidably sealed with the inner wall of the pump housing.

[0011] Furthermore, an upper limiting ring and a lower limiting ring are fixedly connected to the inner part of the bottom end of the pump housing. The limiting block is located between the upper limiting ring and the lower limiting ring. A receiving surface corresponding to the plug column is formed on the upper surface of the limiting block.

[0012] Furthermore, an annular card slot is formed on the outer surface of the plug cover. A snap ring corresponding to the card slot is fixedly connected to the inner bottom wall of the housing. A plurality of guide columns are fixedly connected to the edge of the upper surface of the plug cover.

[0013] Furthermore, the auxiliary pipe includes an upper pipe and a lower pipe. A through hole is formed in the middle of the plug cover. The upper pipe and the lower pipe are inserted and fixed at the upper and lower ends of the through hole. The lower one-way valve group includes a plug bead and a limiting frame. The limiting frame is fixedly connected to the inside of the through hole, and the plug bead is located inside the limiting frame.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, by installing the pump head on the bottle body, with the first liquid stored in the bottle body and the plug cover sealed and fixed at the bottom end of the housing, the second liquid is stored in the accommodation cavity, so that the two liquids are stored separately. When in use, pressing the nozzle causes the plug column and the piston to move downward. At the same time, the plug column contacts the receiving surface on the limiting block and drives the limiting block and the plug cover to move downward and open, so that the second liquid is mixed with the first liquid in the bottle body. Subsequently, only by pressing the nozzle can the mixed liquid be taken out, which is more convenient to use and can well meet the use requirements.

[0017] 2. In the present invention, by fixedly connecting the upper limiting ring and the lower limiting ring to the inner part of the bottom end of the pump housing, the movement of the limiting block can be restricted. When the plug column moves downward, it can contact the receiving surface and drive the limiting block to move to the lower limiting ring. At this time, the plug cover is opened, preventing the limiting block from detaching from the pump housing. Brief description of the drawings

Detailed implementation manners

[0026] This detailed implementation manner is a dual-material mixing pressing pump head, and its structure schematic diagram is as Figures 1-7 shown. The pump head is installed 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. The outside of the pump housing 1 is fixedly connected with an outer shell 5. The infusion tube 3 includes a main pipe 6 and an auxiliary pipe 7. Upper one-way valve group 8 and lower one-way valve group 9 are respectively installed inside the main pipe 6 and the auxiliary pipe 7. The top end of the main pipe 6 is communicated with the nozzle 2. The top end of the auxiliary pipe 7 is located inside the pump housing 1 and is fixedly connected with a limit block 10. A plug cover 11 is fixedly connected to the outer surface of the auxiliary pipe 7. The plug cover 11 is used to block the gap between the auxiliary pipe 7 and the outer shell 5 and form an accommodation cavity 12. The top opening of the bottle body 21 and the cap 4 are hermetically connected by screw threads. The bottle body 21 stores a first liquid. The plug cover 11 is hermetically fixed at the bottom end of the outer shell 5, so that the accommodation cavity 12 stores a second liquid, thereby storing the two liquids separately and not mixing the two materials before use.

[0027] As 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 at 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 accommodation cavity 12 with the auxiliary pipe 7.

[0028] As Figure 3 and Figure 4 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 penetrates through the lower mounting sleeve 101 and is slidably sealed with the lower mounting sleeve 101.

[0029] The upper mounting sleeve 102 can be used to divide the inner part of the pump housing 1 into two parts, which are sealed and fixed to prevent liquid from overflowing from the gap between the main pipe 6 of the pump housing 1, and at the same time, it is also convenient for the fixed installation of the spring 103.

[0030] As Figure 4 and Figure 5 shown: In this embodiment, the upper one-way valve group 8 includes a secondary column 801 clamped 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. A liquid inlet channel 803 communicating with the main pipe 6 is formed between the side surface 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 is fixedly connected with a limiting platform 805 corresponding to the upper surface of the piston 804. A convex block 806 corresponding to the lower surface of the piston 804 is fixedly connected to the outside of the plug column 802. The outer surface of the piston 804 is slidably sealed with the inner wall of the pump housing 1.

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

[0032] As Figure 4 and Figure 5 shown: In this embodiment, an upper limiting ring 104 and a lower limiting ring 105 are fixedly connected to the inner bottom of the pump housing 1. The limiting block 10 is located between the upper limiting ring 104 and the lower limiting ring 105. A receiving surface 106 corresponding to the plug column 802 is formed on the upper surface of the limiting block 10. In this way, the limiting block 10 can only move between the upper limiting ring 104 and the lower limiting ring 105 to avoid detachment. When the plug column 802 moves downward, it can contact the receiving surface 106 and drive the limiting block 10 to move to the lower limiting ring 105, and at this time, the plug cover 11 is opened.

[0033] AsFigure 4 and Figure 6 As shown in Figure 6 , in this embodiment, an annular card slot 1101 is formed on the outer surface of the plug cap 11, a snap ring 1102 corresponding to the card slot 1101 is fixedly connected to the inner bottom wall of the outer shell 5, and a plurality of guide posts 1103 are fixedly connected to the edge of the upper surface of the plug cap 11. In this way, the plug cap 11 can be installed in the gap between the auxiliary pipe 7 and the outer shell 5. At this time, the card slot 1101 is located inside the snap ring 1102, which not only performs preliminary positioning but also can achieve effective sealing.

[0034] As Figure 4 and Figure 6 As shown in Figure 6 , in this embodiment, the auxiliary pipe 7 includes an upper pipe 701 and a lower pipe 702. A through hole 1104 is formed in the middle of the plug cap 11. 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 one-way valve group 9 at the lower part 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, and when the piston 804 moves upward, liquid can be sucked in from the through hole 1104.

[0035] Working principle: When in use, pressing the nozzle 2 drives the main pipe 6, the auxiliary column 801 and the plug column 802 to move downward and compress the spring 103. At this time, the plug column 802 extends out from the lower side of the piston 804 and exposes the liquid inlet channel 803 until the limit platform 805 contacts the upper surface of the piston 804 and drives the piston 804 to move downward. At the same time, the plug column 802 contacts the bearing surface 106 on the limit block 10 and drives the limit block 10 to move downward. During the downward movement of the limit block 10, the upper pipe 701 and the plug cap 11 can be driven to move downward. Since the bonding force between the card slot 1101 on the plug cap 11 and the snap ring 1102 during sealing is small, the plug cap 11 can be opened by simply pressing the nozzle 2 downward with force. At this time, the second liquid stored in the accommodating cavity 12 flows into the bottle body 21, so that the second liquid is mixed with the first liquid in the bottle body 21, and then the nozzle 2 is released and reset under the elastic force of the spring 103;

[0036] After the two liquids are mixed evenly, when the nozzle 2 is pressed again, the piston 804 can reduce the space inside the pump housing 1 during the downward movement. 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 body 21 can be squeezed out for use.

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

[0038] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
