Abstract

The utility model relates to an open-close valve for a sprayer, which makes component parts reduced and mounting and dismounting convenient and is composed of a pressing body, a tooth socket, a cylinder body and a spring. A piston body is composed of a piston handle and a piston, and the upper part of the piston handle is hollow and the lower part is a solid body. The outer margin of the upper part of the piston handle is provided with a convex edge which makes the piston handle penetrate through the tooth socket. In order to open-close fixation, pore space is arranged under the convex edge, and the pore space is covered by the piston in closing. The inner part of the piston is provided with a sealing ring, and the outer margin of the piston is also provided with a sealing ring. The upper part of the cylinder body is hollow, and a convex ring is arranged in the lower part. The utility model is used for a sprayer.

Description

The switching valve body of sprayer

The utility model relates to the switching valve body, refers in particular to the valve body on a kind of liquid dispenser.

The switching valve body of existing liquid dispenser is as shown in Figure 1: by pressing body 11, facing 12, purt pipe 13, purt sleeve pipe 14, seat pipe 15, spring 16, steel ball 17 and cylinder block 18 constitute, purt pipe 13 is arranged in the slotted eye 121 of facing 12, purt pipe 13 tops are engaged with the pressing body 11 that nozzle 111 is arranged, and purt pipe 13 lower end mouth sockets one base 15, base 15 outer rims two sides are provided with respective apertures 151, infiltrate in the seat pipe 15 for liquid such as emulsion or perfume, and hidden cover by purt pipe box 14, seat pipe 15 bottoms are that dish type is solid, steel ball 17 is inserted cylinder block 18,18 mouthfuls of holes of cylinder block from top to bottom dwindle, make the diameter of the end opening hole dia of cylinder block 18 less than steel ball 17, spring 16 places steel ball 17 tops, slotted eye 121 root edges of the upper mouth fit facing 12 of cylinder block 18 make seat pipe 15 bottoms envelope pressing spring 16, and cylinder block 18 lower end mouth sockets one suction pipe 19, though it is good that this structure is controlled spraying, member is many, the cost height, assembly and disassembly inconvenience.

The purpose of this utility model provides a kind of reliable and member minimizing of spraying, switching valve body of simple load and unload sprayer controlled.

The purpose of this utility model is achieved in that the switching valve body of sprayer, it is made of pressing body, facing, cylinder, piston body and spring, piston body is arranged in the slotted eye of facing, the top of piston body and pressing body fit, and sheathed spring and inserting in the cylinder block on piston body, it is characterized in that: piston body is made up of piston handle and piston, piston handle top is hollow, the bottom is a solid body, and the top outer rim is provided with the convex edge, wears facing for piston handle, and is fixing for what open and close, the below, convex edge is provided with hole, is hidden by piston when hole is closed; Internal piston is provided with seal ring, and the piston outer rim also is provided with seal ring; Cylinder deck hollow is provided with prominent ring in the bottom.

Above-mentioned design, the some holes on the piston handle convex edge are gone into rising fluid body and function in the piston handle for liquid; The seal ring of internal piston and the hole of piston handle act on altogether; When the seal ring of piston outer rim and cylinder block start, for the imbibition body; Cylinder deck hollow and piston outer rim seal ring same-action, and the spring same-action on prominent ring and piston handle and the piston has reached the member minimizing; Install and remove convenience and control reliable effect.

Be described further again with accompanying drawing, embodiment below.

Fig. 1 is the open and close valve body structure exploded perspective schematic representation of existing liquid dispenser;

Fig. 2 constructs the exploded perspective schematic representation for the utility model embodiment;

Fig. 3 is the utility model original state schematic representation;

Fig. 4 is the utility model pressed state schematic representation.

Shown in Fig. 2-4: the utility model is by pressing body 21, facing 22, cylinder 23, piston body 24 and spring 25 constitute, piston body 24 is arranged in the slotted eye 221 of facing 22, the top of piston body 24 and pressing body 21 fits, and sheathed spring 25 and inserting in the cylinder block 23 on piston body 24, it is characterized in that: piston body 24 is made up of piston handle 241 and piston 242, piston handle 241 tops are hollow, bottom 2413 is a solid body, and the top outer rim is provided with convex edge 2411, wear facing 22 for piston handle 241, fixing for what open and close, 2411 belows, convex edge are provided with hole 2412, are hidden by piston 242 when hole 2412 is closed; Piston 242 inside are provided with seal ring 2421, and piston 242 outer rims also are provided with seal ring 2422; Cylinder block 23 top hollows are provided with prominent ring 231 in the bottom.Some holes 2412 on piston handle 241 convex edges 2411 are gone into rising fluid body and function in the piston handle 241 for liquid; The seal ring 2421 of piston 242 inside and the hole of piston handle 241 2412 effect altogether; When the seal ring 2422 of piston 242 outer rims and cylinder block 23 starts, for the imbibition body; Cylinder block 23 top hollows and piston 242 outer rim seal rings 2422 same-actions, and spring 25 same-actions on prominent ring 231 and piston handle 241 and the piston 241, and at lower end mouth socket one suction pipe 26 of cylinder block 23.

During use, when not pushing pressing body 21, spring 25 is conflicted on prominent ring 231 limits, piston handle bottom 2413 is through in the spring 25, and seal ring 2421 hides hole 2412, and 2411 of seal ring 2422 and convex edges form gap 243, the mouth hole of outstanding ring 231 is not stopped up in piston handle bottom 2413, the mouth hole manifests, and at this moment, emulsion in the container or perfume etc. enter cylinder block 23 from suction pipe 26 through prominent ring 231.When pressing body 21 is pressed, intert towards real ring 231 piston handle bottom 2413, block the mouth hole of prominent ring 231, it is the same that steely pearl clogs the hole, make the piston head convex edge 2411 of conflicting, hole 2412 manifests, and liquid is promptly from nozzle 211 ejections, because of spring 25 elastic force, 231 mouthfuls of holes of prominent ring show and the answer original state again.
