Abstract
The invention discloses a piston mechanism of an air pressure type sprayer and the sprayer provided with the piston mechanism. The piston mechanism comprises a cylinder body, a piston and a piston rod, wherein the piston and the piston rod are arranged inside the cylinder body in a connected mode, the piston comprises a base body and an annular elastic part arranged surrounding the outer side of the base body, the base body is connected with the piston rod, an annular protruding edge used for preventing the annular elastic part from deforming is arranged at the upper end of the base body, the annular elastic part is arranged below the annular protruding edge, and an annular sealing wall adjacent to the inner wall of the cylinder body is further arranged on the edge of the annular elastic part. The piston mechanism of the air pressure type sprayer and the sprayer provided with the piston mechanism have the advantages that the elastic force of materials and the opening force generated by air pressure are combined, and under the action of the two types of force, the sealing effect of the piston is improved, and use efficiency is improved.
Description
Technical field
The present invention relates to a kind of air pressure type sprayer, particularly relate to a kind of air pressure type sprayer piston mechanism and the sprayer of this piston mechanism is installed.
Background technology
Air pressure type sprayer utilizes the principle of atmospheric pressure difference that liquid medicine or other liquid are become vaporific, is ejected into the utensil on other objects equably.Air pressure type sprayer generally includes cylindrical shell, nozzle mechanism and piston mechanism, nozzle mechanism is arranged on cylindrical shell top, piston mechanism is arranged on inner barrel, piston mechanism comprises cylinder body, piston rod and piston, piston rod is connected with piston and is arranged on cylinder interior, the piston mechanism of conventional gas formula sprayer adopts a kind of piston structure of O-ring seals, such as: it is a kind of in the piston of liquid dispenser that China Patent No. has been the disclosure of the invention of CN91217070.0, be made up of disk and rubber seal, rubber seal is installed in the arc groove in the middle part of disk periphery, for being sealed and matched between the rubber seal of this piston under using state and pump inwall.The shortcoming of conventional piston mechanism is poorly sealed, increases twitch and inflates number of times, inefficiency; The material antiseptic poor performance of the rubber ring adopted, can not use in chemical solution; Rubber ring wears no resistance, and service life is short.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of air pressure type sprayer piston mechanism, can solve the shortcoming that conventional piston mechanism seals is not tight, and the present invention provides a kind of air pressure type sprayer with above-mentioned functions further.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of air pressure type sprayer piston mechanism, comprise cylinder body, piston and piston rod, piston is connected with piston rod and is arranged on cylinder interior, described piston comprises matrix and is looped around the cyclic spring parts outside matrix, described matrix is connected with piston rod, it is characterized in that described matrix upper end is provided with the annular flange flange for keeping out cyclic spring part distortion, cyclic spring parts are arranged on the below of annular flange flange, the edge of described cyclic spring parts is also provided with the ring packing wall near inboard wall of cylinder block.
Further preferred version is: described cyclic spring parts are made up of elastoplast.The material of conventional gas formula sprayer is made up of rubber usually, changes now and is made up of elastoplast, so just makes piston have good corrosion resistant characteristic, and because elastoplast production cost is low, effectively can reduce production cost.
Further preferred version is: described ring packing wall is vertically connected relative to the upper end of cyclic spring parts.Vertical being connected farthest can increase the contact area of ring packing wall and inboard wall of cylinder block, increases sealing effectiveness.
Further preferred version is: ring packing wall relative to the upper end of cyclic spring parts in being greater than the outward-dipping state that 90 degree are less than 110 degree.Make ring packing wall inclined relative to the upper end of cyclic spring parts, can make that the part bottom of ring packing wall is limited to be contacted with cylinder interior, both frictional force is less, during supercharging, strut ring packing wall under the influence of air pressure, increase the contact area of sealing ring, frictional force becomes large thereupon.When cylinder interior pressure is less, the seal degree of ring packing wall is required and frictional force also lower, supercharging can be realized by less power; When in-cylinder pressure is larger, the seal degree of ring packing wall is required and frictional force also higher, supercharging needs the power used also to increase.The frictional force overcome required for the program can change automatically according to the boost demand of sprayer, increases service efficiency.
Further preferred version is: the diameter of the upper end of described cyclic spring parts is less than the diameter of the inside of described cylinder body.Cyclic spring parts the sealing effectiveness of bottom poor, do not contact cylinder interior and can save unnecessary frictional force, improve service efficiency.
Further preferred version is: the diameter of described matrix is less than the diameter of the inside of described cylinder body.Matrix does not have sealing effectiveness, and the diameter that base diameter is less than the inside of cylinder body can make matrix conveniently pass in and out cylinder body.
A kind of air pressure type sprayer, is characterized in that the air pressure type sprayer of the feature of the claim 1-8 at least comprised described in.
Compared with prior art, advantage of the present invention is the annular flange flange arranged in matrix upper end, can prevent cyclic spring parts from producing distortion backward when sprayer supercharging, increases the service life of cyclic spring parts; Piston is while twitching up and down and down calming the anger, the ring packing wall made except elastomeric material provides one to except the pressure of inboard wall of cylinder block, the air pressure produced when pressing down can also be relied on again to strut ring packing wall, under the effect of dual-pressure, complete sealed cylinder block, in air press-in sprayer, reduce and twitch number of times, improve service efficiency.
