Limitation.
The working principle of the utility model is as follows:
The foam pump of the utility model is under transport or free state, in conjunction with shown in Fig. 1, Fig. 4 and Fig. 5, due to being provided with
Buckle 3, big 5 lower end of piston are that lid closes the through-hole 41 being arranged on ontology 4, and through-hole 41 is made to be constantly in sealing state, two-way pad
The siphonal lobe 72 of valve 7 and the tonifying Qi hole 51 being arranged on big piston 5 be in micro- closed state, and small piston 831 and ontology 4, subpost 832
Between be in sealing state, at this time buckle 3 do not extract before push head 2 can not；
In conjunction with shown in Fig. 1 and Fig. 6, (black arrow represents air flow direction in figure), when buckle 3 extract and by head 2 it is downward
When pressing, head 2, big piston 5, connecting rod 81, liquid squeeze out component 83 (i.e. small piston 831, subpost 832, piston seat 833 etc.)
It synchronously moves down, compressed spring 82, small piston 831 is because under the effect of the friction stree of interference fit and in its sliding space
Interior delay moves up, and the internal lobe 71 is in non-tight state with 812 bottom of ennation, then opens and connecting rod 81
Original place is in the gas distribution channel (not shown) of sealing, at the same time, because air pressure inside increase make the siphonal lobe 72 of two-way pad valve 7 with
The tonifying Qi hole 51 that big piston 5 is arranged in is in sealing state, and the gas positioned at gas chamber is made to flow through gas distribution channel (not shown)
And flow to Netcom 6 and mixed with liquid, and small piston 831 moves up, and opens infusion hole (being not shown in the figure, be below), glass
Glass pearl 834 seals inlet opening (being not shown in the figure, be below) in the increase of self gravity and interior pressure, and liquid passes through infusion
Hole enters infusion road, then flows to Netcom 6 and gas mixing, and then gas and liquid flow are set the net of the microcephaly in Netcom 6
Cloth (being not shown in the figure, be below) forms foam, in the screen cloth for then flowing through the major part being arranged in Netcom 6 that foam is fine and smooth
Change, (is not shown in figure by the foam of exquisitenessization along the head mouth spray that the perfusion tube (not shown) of head flows to head 2 finally
Go out out) to external；
In conjunction with shown in Fig. 1 and Fig. 7, when the downward push of head 2 to 4 bottom of ontology (after loosing one's grip), due to spring 82
Restore, head 2, big piston 5, connecting rod 81, liquid squeeze out component 83 (i.e. small piston, subpost, piston seat etc.) synchronously upwards
Mobile, small piston 831 is moved down because being delayed under the effect of the friction stree of interference fit and in its sliding space, big piston
5, which move up the internal lobe 71 of two-way pad valve 7 and 812 bottom of ennation in the process, is in sealing state, for closing gas transmission
Channel is to prevent gas-liquid to be back to the gas chamber in ontology 4, at the same time, keeps the indoor vacuum of gas negative because big piston 5 continues to move up
Pressure increases, and the siphonal lobe 72 of the two-way pad valve 7 and the tonifying Qi hole 51 are in non-tight state, and gas flows to gas from tonifying Qi hole 51
Room, then small piston 831 moves down, and closes the infusion hole (not shown) matched with subpost 832 to prevent liquid from returning
Stream, then small piston 831, which continues to move up, increases the vacuum inner suction of liquid chamber, and bead 832, which opens infusion hole, makes liquid
Liquid chamber is flowed to, air-flow is also made to flow to gas chamber (in bottle) from through-hole 41, the tonifying Qi hole 51 for being arranged in big piston 5 to prevent vacuum
Interior pressure, and head 2 is made to recoil to 1 top of thread, complete the circulation action of the entire foam pump of the application.
As described above, the utility model relates to a kind of spring external pump head, have the advantages that
After the utility model utilizes above-mentioned spring external pump head, compared with prior art, due to using such knot
Structure is equipped with integrally formed ennation by the top of the bar body in connecting rod, in conjunction with the internal lobe and siphonal lobe of two-way pad valve,
It can ensure stable structure in use process, avoid the occurrence of loosening, there is preferable air-tightness, therefore ensure that preferably spraying effect
Fruit；Meanwhile because eliminating installation valve, keep the assembly of components eased, convenient, at low cost.
In conclusion the utility model effectively overcomes various shortcoming in the prior art and has high industrial exploitation value
Value.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model
All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of the utility model.
