Description

Aerosol apparatus with monolayer leather cup

Technical field

This utility model relates to daily living article field, particularly to a kind of aerosol apparatus with monolayer leather cup.

Background technology

Leather cup in pump for sprayer is the vital part affecting pump suction performance, and the commonly used bowl-type leather cup of existing pump for sprayer, this leather cup there is problems in that two way seal when (1) moves up and down is poor；(2) it is easily deformed；(3) cylindricity of pump is required height.Therefore in use the suction performance of pump is poor, and the life-span of leather cup is short.

At present, application number be 98228461.6 Chinese patent disclose the inverted knapsack sprayer of pump, wherein patent accompanying drawing discloses, including staving and be fixed on the pump on staving, described pump includes cylinder and is positioned at the piston rod of cylinder, the end of described piston rod is provided with leather cup, at the bottom of described leather cup includes bowl, be positioned at bowl at the bottom of the rim of a bowl of edge, described the rim of a bowl is horn-like and arranges down, being circumferentially with annular grooving on described the rim of a bowl medial wall, described annular grooving is located close to side, the rim of a bowl edge.

The inverted knapsack sprayer of this pump, although the setting by annular grooving, the rim of a bowl edge has the elasticity of abundance, the sealing making the rim of a bowl overall is better, but under pump in the process of pressure, easily making the rim of a bowl edge stress deformation of thinner thickness, declining thus being easily caused the rim of a bowl overall construction intensity.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that the aerosol apparatus with monolayer leather cup providing a kind of the rim of a bowl structural strength high.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of aerosol apparatus with monolayer leather cup, including staving and be fixed on the pump on staving, described pump includes cylinder and is positioned at the piston rod of cylinder, the end of described piston rod is provided with monolayer leather cup, at the bottom of described monolayer leather cup includes bowl, be positioned at bowl at the bottom of edge be horn-like and the rim of a bowl of arranging down, edge, described the rim of a bowl medial wall is provided with annular grooving, it is characterized in that: described annular grooving is circumferentially with retainer ring away from the notch place at the rim of a bowl edge.

Pass through technique scheme, in the process pressing down pump, according to the elastic setting of the rim of a bowl, swelling between the rim of a bowl and cylinder medial wall, air-tightness is good, air tight, effectively providing pressure, the lower thickness of the rim of a bowl edge to air chamber, elasticity is more sufficient, thus causing the rim of a bowl edge to be more susceptible to force deformation, but by the setting of retainer ring, from any direction, the rim of a bowl inwardly being extruded, the rim of a bowl edge is provided 360 ° and strengthens fixing by the retainer ring of ring-type, thus avoiding the rim of a bowl edge stress deformation, thus improve the structural strength that the rim of a bowl is overall；And in the process of pump pull, by the retainer ring support to the rim of a bowl edge, the rim of a bowl edge pushes against with pump medial wall all the time, improves the air-tightness of monolayer leather cup, thus strengthening pump to extract the effect of medicinal liquid.

Preferably, being provided with at least one the first reinforcing rings at the bottom of described bowl, described first reinforcing ring extends to deviating from the rim of a bowl side, and every described first reinforcing ring all with the setting of piston rod concentric.

By technique scheme, under piston rod in the process of pressure, extruding force is concentrated at the bottom of bowl by the rim of a bowl, thus bearing main extruding force at the bottom of bowl, setting by the first reinforcing ring, it is ensured that the structural strength in circumference at the bottom of bowl, is not susceptible to deformation when being squeezed at the bottom of bowl.

Preferably, being provided with at least one the second reinforcing rings at the bottom of described bowl, described second strengthens hoop extends near the rim of a bowl side, and every described second reinforcing ring all with the setting of piston rod concentric.

Pass through technique scheme, in the process taken out on the piston rod, swelling between the rim of a bowl and the medial wall of cylinder, the rim of a bowl shrinks to the central point of cylinder, thus being subject to the contractility of slight the rim of a bowl at the bottom of bowl, setting by the second reinforcing ring, it is ensured that the structural strength in circumference at the bottom of bowl, is not susceptible to deformation when being subject to contractility at the bottom of bowl；And under piston rod during pressure, the second reinforcing ring further ensure bowl at the bottom of structural strength in circumference, be not susceptible to deformation when being squeezed at the bottom of bowl.

Preferably, the height of described first reinforcing ring is more than the height of the second reinforcing ring.

By technique scheme, strengthening hoop both sides and protrude and arrange, when under piston rod, pressure and piston rod pull upwardly on, piston rod presses down the top at the bottom of making bowl to bear bigger extruding force, the first highly higher reinforcing ring, further increases the structural strength of monolayer leather cup.

Preferably, described pump bottom thread is connected to water suction seat, being provided with ball valve, water absorption channel in described water suction seat, described ball valve includes ball channel, is positioned at ball channel and for covering the ball of water absorption channel, and described ball channel is provided with gag lever post near pump passway place intersection.

Pass through technique scheme, when pump is taken out, ball in ball valve is upwards picked up under the effect of suction, thus opening the water absorption channel of water suction seat, after ball is picked up, by gag lever post arranged in a crossed manner, ball is served barrier effect, limit ball excessive axial float in ball channel, make ball somewhat open water absorption channel water supply stream to pass through, under pump during pressure, from the ball timely clogging water absorption channel of energy close to water absorption channel mouth, pump is made to have higher pressure when pressing down, thus improve the effect of drawing water of pump；And gag lever post arranged in a crossed manner, forms four through holes, makes gag lever post have the effect of filtration, it is to avoid thread, strip foreign body enters in pump, thus affecting the result of use of pump.

Preferably, described ball channel is provided with rubber washer near pump passway place, and described gag lever post is shaped in rubber washer.

Pass through technique scheme, when the seat that absorbs water is threaded in bottom pump, rubber washer not only acts as the effect of buffering between water suction seat and pump, and when the seat that absorbs water is tightened, rubber washer can by swelling between water suction seat and pump, ensure the air-tightness between water suction seat and pump, thus improve the drawing liquid efficiency of pump.

Preferably, the cross point of described gag lever post is positioned at rubber washer center.

Pass through technique scheme, two gag lever posts arranged in a crossed manner, ball, when being picked up, can not only effectively stop the excessive rolling of ball, and cross point is positioned at the center of rubber washer, avoid ball inlay card in through-holes, and gag lever post arranged in a crossed manner thus forming four through holes on rubber washer, four through holes not only without influence on medicinal liquid by fluency, also can play filter effect, avoid foreign body to enter in pump, affect the normal use of pump.
