Description
Technical field
The present invention relates to a kind of fluid preparation pumping atomising installation, be meant a kind of fluid-dispensing pump especially.
Background technology
Fluid preparation spraying pumping installation is a kind of product that is widely used in fields such as medical treatment, cosmetics, perfume; Its function is to distribute ejection to form spraying fluid preparation, and this fluid-dispensing pump is like patent No. CN 200680044054.1 and number of patent application CN 200980126767.6 disclosed fluid-dispensing pumps or the like; It mainly comprises water core, piston and dispensing head; Said water core comprises the plunger and the pump housing, and said plunger is blocked in the dispensing orifice of said dispensing head, and is provided with in the said pump housing and decides dose chamber; Has the auxiliary piston that annular flange flange constitutes on the said pump housing; Said piston is fixed on through fixed ring seals on the reagent bottle bottleneck of splendid attire fluid preparation, and said piston can be decided to slide in the dose chamber in said, and said auxiliary piston slidably is arranged in the distribution cavity of said dispensing head; Saidly decide dose chamber and be connected with said distribution cavity; Said piston in said decide in the dose chamber to slide fluid product is entered in the said distribution cavity, thereby hydraulic pressure increases and promotes said auxiliary piston and in said distribution cavity, slide and break away from said dispensing orifice with the said plunger that links in the said distribution cavity, thereby externally distribute the potion fluid product.Above-mentioned plunger is used to avoid between the double start of piston, and the fluid product in the pump is polluted, and when ceasing, is actuated to its occlusion locations.
Plunger on the water core can both reach the effect of the said dispensing orifice of plug for seal preferably as stated, but it still exists a series of problem in the specific implementation, the concrete narration as follows: at first; Be provided with aerosol type portion in the bobbin of dispensing head as stated; Make formulation products when discharging, can form aerosol with the form of vortex motion, but said aerosol type portion just reserves a volute chamber at the dispensing orifice upper reaches of said dispensing head, still said plunger can change the geometric configuration of said aerosol type portion usually; Thereby during the jet fluid product; Can cause the aerosol state labile of ejection, even can spray, thereby damage the quality of spraying with the form of waterline; Secondly; Plunger need play the effect of stopping up dispensing orifice and the said water core of axial lead; Said for this reason plunger need with the socket inwall of said dispensing head between form the long section of cooperation; The axial side periphery of said plunger matches with cooresponding socket inner wall section in the said dispensing head, and this makes said plunger need break away from that cooperate could external distributing fluids product with the socket inwall of said dispensing head, thereby causes the stroke of said auxiliary piston in said distribution cavity bigger; Thereby the airtight construction between auxiliary piston and the distribution cavity there is higher requirement; And when the stroke of said auxiliary piston increased, the invalid volume in the said distribution cavity also further increased, and was unfavorable for that fluid distributes quantitatively.More than be existing fluid-dispensing pump existing deficiency on its structure in the specific implementation, to these weak points, prior art has further improved necessity very much, and the present invention is to these not enough a kind of evolutionary approach that is proposed.
Summary of the invention
The present invention provides a kind of fluid-dispensing pump; Its technical problem underlying to be solved is: at first; The geometric configuration of the aerosol type portion in its dispensing head of traditional fluid-dispensing pump is vulnerable to the influence of said plunger; The formed aerosol state labile of fluid product of ejection, even can form waterline, be unfavorable for user's use; Secondly; Form the long section of cooperation between the socket inwall of said plunger and dispensing head; Said plunger need break away from the socket inwall of dispensing head and cooperate externally distributing fluids product, thereby causes the big problem of the stroke of auxiliary piston in said distribution cavity of the said plunger of interlock.It more than is technical problem underlying to be solved by this invention.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: the present invention provides a kind of fluid-dispensing pump, and it is arranged on the holder of fluid preparation, and it comprises water core, piston and dispensing head; Said water core comprises the plunger and the pump housing; The said pump housing of the coaxial connection of said plunger, the said plunger axial motion of said pump housing linkage has the dose chamber of deciding in the said pump housing; Also be provided with the auxiliary piston of circular flange-like on the said pump housing, be positioned at the corresponding side of said auxiliary piston and said plunger on the said pump housing and offer intercommunicating pore; Said piston is decided to slide in the dose chamber in said with the leak free mode, so that move the fluid product of suction or discharging doses each time, said piston is fixedly installed on the bottleneck of fluid containment bottle through a fixed cap; Said dispensing head is the jet pipe of an adaptation human body nasal cavity; The top of said dispensing head is provided with said dispensing head inner chamber of a UNICOM and extraneous dispensing orifice, and said water core can be arranged in the said dispensing head in axial sliding, and said plunger is arranged on the upper reaches that are positioned at said dispensing orifice in the said dispensing head; And can be movable between the make position of said dispensing orifice and open position; Said plunger is held the make position at said dispensing orifice by an elastic component, the auxiliary piston on the said pump housing can in said dispensing head, axially slide and and the inner tubal wall of said dispensing head between be sealed and matched, at the upper reaches of said dispensing orifice; Surround into distribution cavity between the inner tubal wall of said auxiliary piston and said dispensing head; And said distribution cavity decides to be connected through said intercommunicating pore between the dose chamber with said, it is characterized in that: be provided with lining with the corresponding position of said plunger in the said distribution cavity, said lining is interference fitted on the inner tubal wall of said dispensing head; Said plunger slidably is plugged in the said lining; Be reserved with a fixing aerosol type portion between said lining top and the said dispensing orifice, the top of said lining offers discharge orifice, and said discharge orifice is communicated with said distribution cavity and said aerosol type portion; Said plunger is holding on said discharge orifice under the effect of said elastic component, and the leak free shutoff is on said discharge orifice.
