Specific implementation mode

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.

As Figure 1-Figure 5, the utility model is realized in this way, the pump head includes being coaxially disposed according to this from the top down Head 2, outer cover 4, liquid storage pipe 10 and suction pipe 14, be structurally characterized in that, it is same according to this from the top down between head 2 and liquid storage pipe 10 Axis is provided with mesh 3, gas chamber gland 5 and communicating pipe 8, and bead 13, the bottom of communicating pipe 8 are equipped between liquid storage pipe 10 and suction pipe 14 Portion is socketed with piston 12；Space wherein between liquid storage pipe 10, communicating pipe 8 gentle chamber pressure lid 5 is gas chamber, bead 13, liquid storage Space between pipe 10 and communicating pipe 8 is liquid chamber；The bottom of gas chamber gland 5 is additionally provided with control gas chamber and mesh 3 and outside 8 periphery of communicating pipe of the blade 7 of connection, 12 top of piston is surrounded with compressed spring 9, and the lower part of communicating pipe 8 is equipped with and piston 12 The inlet opening 801 that cooperation control mesh 3 is connected to liquid chamber；In assembly, head 2 is sleeved on 5 top of gas chamber gland, and and gas chamber Gland 5 is connected together, and gas chamber gland 5 is connected to the top of communicating pipe 8, and the blade 7 is to coordinate control gas with gas chamber gland 5 Room and mesh 3 and the external valve being connected to, and piston 12 can be fixed on 10 inner wall of liquid storage pipe, it is slidably connected with communicating pipe 8, And when communicating pipe 8 being in initial position under the effect of compressed spring 9, piston 12 blocks closing inlet opening 801, this makes mesh 3 close with liquid chamber, and press head 2 in external force so that when communicating pipe 8 moves downwardly to suitable position, inlet opening 801 with Move downward and be detached from piston 12, at this time inlet opening 801 and liquid chamber together with, to those skilled in the art, inlet opening 801 with the displacement positive correlation of the cooperation position and head 2 of piston 12, the position setting inlet opening 801 moved down according to head 2 With 12 relative position of piston, to realize above-mentioned valve opening and closing function.

In the specific implementation, the blade 7 includes siphonal lobe 701 and internal lobe 702, and wherein siphonal lobe 701 is located at gas chamber and outside Communication port at, internal lobe 702 is located at the communication port of gas chamber and mesh 3, gas chamber gland 5 and 702 position pair of siphonal lobe 701 and internal lobe Should place be respectively equipped with blade compact heap 501, as shown in Figure 4.When in use, it by pressing head 2 downwards, presses manually First 2, gas chamber gland 5 moves downward, and the blade compact heap 501 being located on gas chamber gland 5 compresses siphonal lobe 701 so that gas chamber with it is outer Portion's connectivity part sealing, and since gas chamber is extruded, volume reduces, air pressure increases, and internal lobe 702 is opened with blade compact heap 501, Positioned at the indoor gas flow mesh of gas 3；The gas chamber gland 5 moved downward simultaneously, which pushes down on, to be moved down communicating pipe 8, feed liquor Hole 801 is detached from piston 12 with moving downward, and liquid chamber is through inlet opening 801 and mesh 3 together with being located at the indoor liquid of liquid Enter mesh 3 through inlet opening 801 and 8 inner cavity of communicating pipe, and with the gas mixing that flows to mesh 3, the foam of formation is by head 2 Head mouth discharge；When hand unclamps, head 2 returns, and in 8 return-to-home position of gas pressure lower chamber gland 5 and communicating pipe, arranges at this time Going out the liquid chamber after liquid, there is certain vacuum, the bead 13 as check valve to be opened under gas pressure, pass through suction pipe Liquid in bottle is drawn into liquid chamber, the liquid that supplement liquid chamber had previously been discharged by 14；In terms of gas chamber, the gas chamber gland of return 5 make blade compact heap 501 be closed with internal lobe 702, the communication port of closed air chamber to mesh 3, and the blade compact heap of the other side 501 are detached from siphonal lobe 701 so that gas chamber is connected to outside, there is the gas that external complement gas chamber is lost in, and pump head is returned at this time Initial state, then head 2 is pressed, the process that repeatable foam pumps out, and in the whole process, liquid is through liquid chamber, inlet opening 801 and communicating pipe 8 enter mesh 3, until pump out by pump head, the dirt of liquid will not be can avoid with the metal pieces into contact such as spring Contaminate risk.

In order to improve the reliability of pump head work, the communicating pipe, 8 top was additionally provided with the gear liquid with the sealing cooperation of internal lobe 702 Flange 802, when head 2 returns, communicating pipe 8 correcting action, gear liquid flange 802 on communicating pipe 8 at this time and internal lobe 702 Cooperation prevents liquid from returning to liquid chamber.

Certainly, the utility model also designs blade 7, and siphonal lobe 701 and internal lobe 702 are that bending direction is opposite Arc spring lamination, so that siphonal lobe 701 and internal lobe 702 and the blade compact heap 501 of gas chamber gland 5 coordinate, with siphonal lobe 701 and internal lobe 702 cooperations control gas chamber and external handshaking procedures well.

Simultaneously, the ride comfort of pump head work depends on the reliability that compressed spring 9 works, in the specific implementation, living 12 top of plug is socketed with spring base 11 communicating pipe 8, and the lower part of compressed spring 9 is between spring base 11 and communicating pipe 8, spring The cooperation of seat 11 and communicating pipe 8 can guarantee the flexible stability in 9 lower part of compressed spring.

It is connected with gasket seal 6 between the outer cover 4 and liquid storage pipe 10, improves the leakproofness of pump head, while head 2 Top is additionally provided with the dust cover 1 being connected with outer cover 4, and dirt is avoided to invade in pump head, also avoid external force surprisingly touch extruding by First 2, improve the reliability used.
