Description

One has more fluid apertures aerosol spray lid

Technical field

The present invention relates to a kind of atomising installation, belong to product conveying unit technical field, particularly relate to one and have more fluid apertures aerosol spray lid.

Background technology

As everyone knows, atomising installation can be used for carrying multiple product, as normal pressure atomizing pump can be used for fluid to be transported on the surface or spatial volume from container.Similar therewith, aerosol spray device is used for being ejected on the surface by aerosol content or being ejected in spatial volume.Aerosol spray device type is a lot, typical aerosol spray device is button-type, it comprises fluid hole and the attaching parts with valve, and this valve connects product container then, and product to be discharged on the surface by valve and button or in spatial volume by the actuating of button from aerosol container.

In order to increase aesthetics and the ease of use of product, actuator and aerosol plastic housing being made entirety in recent years, being commonly referred to spraying Conjoined cover, aerosol abhiseca and valve can be covered in, actuator can be made again more convenient.Although this spray cap operation more for convenience, but unfortunately, this kind of spray cap often only has a simple fluid hole, when in use adopting same pressing dynamics, substantially identical from the spray amount of fluid hole ejection, be difficult to regulate spray volume size, ejection speed and jet length is limited, spray area and scope are comparatively concentrated, more difficultly meet customer's new demand of using of large area on a large scale.

In order to solve the problem, a kind of regulating flow quantity self-locking spray lid and a kind of multifunctional spraying lid is individually disclosed in Chinese patent CN103738593A and CN104590699A, but spray lid disclosed in patent CN103738593A and be more prone to adjust flux among a small circle, and patent CN104590699A is catheter channel and cloud point passage two power and energy, more than spraying lid can adjust flux size to a certain extent, but when aerosol needs large area use on a large scale, owing to spraying the restriction of speed and jet length, need long-time pressing spray lid, cause finger fatigue, more demands of customer can not be met.

Summary of the invention

In order to overcome above-mentioned technological deficiency, the object of this invention is to provide one and having more fluid apertures aerosol spray lid, its structure is simple, easy to use, and effectively can increase ejection speed and ejection scope, and then significantly promotes ejection effect.

In order to reach above object, the present invention adopts following scheme:

One has more fluid apertures aerosol spray lid, comprises lid, and described lid is connected with shower nozzle, and described shower nozzle is provided with multiple fluid hole.

One of the present invention has more fluid apertures aerosol spray lid, and described shower nozzle includes press head; Be arranged on this press head connection pipe vertically downward; And to be arranged in this press head and the multiple fluid holes be connected with described connection pipe.

The not special requirement of lid size having more fluid apertures aerosol spray lid of the present invention, lid diameter mainly coordinates (being generally 45mm-65mm) according to the size of tank body is selected; Lid height preferably uses 50mm-80mm, and the aerosol valves throw of lever can be caused inadequate when height is less than 46mm higher than 80mm can cause being difficult to grip use inconvenience, feed liquid exports ejection poor effect, and the height of the connection pipe corresponding to it is 45mm-60mm.

The not special requirement of diameter having more the connection pipe that fluid apertures aerosol spray covers of the present invention, is mainly proportioning valve shank diameter size; How many connection pipe height is determined according to the moulding of aerosol spray lid and selected fluid apertures quantity and fluid hole diameter, but affects by the use comfort that overall Conjoined cover holds, and preferably uses 45mm-60mm.

One has more fluid apertures aerosol spray lid, and described fluid hole preferred amount is 2-5, the optional 0.3mm-1.4mm in aperture, hole depth 7.0mm-13.5mm (described hole depth is the distance of spraying port to connection pipe axle center of fluid hole).The hole depth of fluid hole is to the atomizing angle of aerosol spray and spray apart from relevant, short-bore can obtain wider atomizing angle and spread of spray deeply, elongated hole deeply then can obtain narrow atomizing angle and slightly long jet length, atomizing angle with duration can be avoided surveying in spray cap and form atomizing particle sputtering, reduces pollution when using.But hole depth is also unsuitable too short, too short easily making causes liquid medicine contamination in disjunctor aerosol lid inner formation sputtering during medicine liquid spray, and serious meeting flows out in customer's hand from Conjoined cover and tank body slit, increases drug exposure risk.And the oversize meeting of hole depth causes being difficult in injection moulding process the demoulding, shaping qualification rate reduces.

According to product user demand and Conjoined cover preparation technology requirement, preferred hole depth is at 8.0mm ~ 13.2mm.

Of the present invention to have more the fluid hole quantity that fluid apertures aerosol spray covers be choose according to the ejection speed of different model valve, common ejection speed valve (1g/s-5g/s), namely adopts fluid hole quantity to be the spray cap of 2-3; Special fast type sprays the rate valve (5g/s-10g/s) that hastens, and namely adopts the spray cap of fluid hole quantity 4-5.The metered fuel orifice valve of 2 × 0.51mm as comparatively conventional in daily aerosol products, ejection speed is (2g/s ~ 4g/s), and we are preferably 0.4mm ~ 0.8mm to the hole internal diameter of fluid hole, quantity 2 ~ 4.Although the spray cap design being greater than 5 fluid holes can improve spread of spray, but for spray rate there is no significantly improve and cost of manufacture can increase (as Design of Dies be responsible for, the demoulding is difficult, reject rate is high), and connection pipe length can be caused long, spray cap whole height exceeds human body and is suitable for range of use, certainly adopts mechanical type automatic sprayer to make the quantity that can continue to increase fluid hole.

In general fluid hole hole internal diameter is less, under the condition that other parameters are identical, as fluid hole shape and the degree of depth, the uninterrupted determined by valve, when all parameters such as the physical property of content ejection pressure and content are all identical, the mist droplet particle size of ejection is thinner.But fluid hole hole internal diameter can not size, is such as less than 0.25mm aperture just because seldom being used than being easier to be blocked by foreign material.The selection principle in general fluid hole aperture is, fluid hole aperture generally should be more bigger than the metered fuel orifice on valve rod, to obtain comparatively uniform droplet Size Distribution, improves pulverability.Valve rod metered fuel orifice minimum-value aperture can reach 0.13mm, but this aperture is difficult to work it out on mould, and laser beam can be adopted to process, but current technological condition is difficult to the stability of ensuring the quality of products, and this aperture easily forms the problems such as blocking.Generally practical minimum valve rod gauge hole diameter is 0.25mm, and there are 0.33mm, 0.46mm, 0.7mm, 0.88mm, 1.02mm, 1.3mm, 1.4mm etc. in conventional aperture.According to for many years to the test of the actual atomizing effect in different fluid hole apertures, the preferred 0.4mm-1.3mm of interior diameter of spray cap fluid hole.

In addition, spray cap fluid hole can be made into Straight hole, positive taper hole and reverse taper hole according to the shape difference in depth direction.Straight hole is cylindrical, and two is equally large, and its spray effect is more concentrated, and the spray angle of ejection feed liquid is little; Positive taper hole is inner small and outside big, can obtain better crushing effect than Straight; Reverse taper hole is interior large outer little, except having better crushing effect, can also obtain broader spray effect.The shape of spray cap fluid hole can be selected according to the different demands of different product.

One has more fluid apertures aerosol spray lid, and described lid bottom has the ring-like bayonet socket be connected with tank body bottleneck, and the connection pipe of shower nozzle coordinates with the valve on aerosol.

One has more fluid apertures aerosol spray lid, and described press head upper end is provided with pressing cambered surface, described pressing cambered surface is provided with and is convenient to the anti-skidding tongue of pressing press head.

In addition as the material of spray cap, be applicable to using polyethylene, polypropylene, dimethoxym ethane resin, nylon and other engineering plastic resins, by such as vacuum, air pressure or the mode such as injection moulding, punch forming.Selected engineering resin needs the swelling erosion that can tolerate most of solvent and the propellant used in aerosol products.Need suitably to add some plasticizer and other additives, spalling when being installed on valve rod to avoid spray cap in these resins simultaneously.

In sum, the present invention has following beneficial effect relative to prior art:
