Abstract
The utility model relates to the field of cleaning products, in particular to an improved water injector, which comprises a piston cylinder, a pump cover, a piston, a pump, a piston spring, a water valve, a water inlet and a water outlet. The piston is arranged at the lower end of the piston cylinder and penetrates through the pump cover to be arranged inside the pump, the pump cover is connected with the upper end of the pump, the piston spring is arranged inside the pump, one end of the water valve is connected with the pump and the water inlet, and the other end of the water valve is connected with the water outlet. The improved water injector is characterized in that a piston bush is arranged between the piston and the piston spring and abutted to the piston. The water injector is simple in structure and fine in leakproof effect.
Description
Technical field
The utility model relates to the cleaning supplies field, specifically a kind of improved water injector.
Background technology
Mop capable of spraying water is typically equipped with a water injector in the market, in the process that mops floor, the water in the water tank is sprayed out, and is convenient to mop floor; But water injector has certain life-span, uses a period of time to be easy to generate drainage afterwards; Be that the elasticity variation contacts not tight with pump housing inwall because piston is aging after growing service time; Cause leaking, and then influence the normal use of mop capable of spraying water.
The utility model content
The utility model provides a kind of water injector of simple in structure, good leak-proof effect.
The utility model is realized through following technical proposals: a kind of improved water injector; Comprise piston boit, pump cover, piston, the pump housing, piston spring, water valve, water inlet and delivery port, said piston is located at the piston boit lower end, passes pump cover and is located at pump housing inside; Said pump cover is connected with pump housing upper end; Said piston spring is located at pump housing inside, and said water valve one end is connected with water inlet with the pump housing, and the other end is connected with delivery port; Be provided with piston bush between said piston and the piston spring, said piston bush and piston are inconsistent.
It is conical that said piston bush is, and the centre is provided with through hole, and said piston passes said through hole.
Said water valve comprises valve nozzle, water inlet body, silica gel valve, spool and nozzle, and said valve nozzle is connected with water inlet through the water inlet body, and said spool is located in the silica gel valve, and is located at together in the nozzle, and said nozzle is connected with delivery port.
The beneficial effect that the utility model brought is: in the utility model, said improved water injector can prevent the drainage after piston wears out effectively after having set up piston bush; It is conical that said piston bush is; The centre is provided with through hole, and said piston passes said through hole, so the inwall of the outer wall of piston bush and piston is inconsistent; Piston bush has the effect of a support to piston; Even piston also can be attached to pump housing inwall after wearing out and following the string well under the support of piston bush, prevent to leak.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the structural representation of the said improved water injector of the utility model.
The label that component names is corresponding among the figure is following: 1, piston boit; 2, pump cover; 3, piston; 4, the pump housing; 5, piston spring; 6, water valve; 61, valve nozzle; 62, water inlet body; 63, silica gel valve; 64, spool; 65, nozzle; 7, water inlet; 8, delivery port; 9, piston bush; 91, through hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to detail: as shown in Figure 1 as the embodiment of the said improved water injector of the utility model, comprise piston boit 1, pump cover 2, piston 3, the pump housing 4, piston spring 5, water valve 6, water inlet 7 and delivery port 8; Said piston 3 is located at piston boit 1 lower end; Pass pump cover 2 and be located at the pump housing 4 inside, said pump cover 2 is connected with the pump housing 4 upper ends, and said piston spring 5 is located at the pump housing 4 inside; Said water valve 6 one ends are connected with water inlet 7 with the pump housing 4; The other end is connected with delivery port 8, is provided with piston bush 9 between said piston 3 and the piston spring 5, and said piston bush 9 is inconsistent with piston 3.Said improved water injector can prevent the drainage after piston 3 wears out effectively after having set up piston bush 9.
In the present embodiment, it is conical that said piston bush 9 is, and the centre is provided with through hole 1, and said piston 3 passes said through hole 91.Therefore the inwall of the outer wall of piston bush 9 and piston 3 is inconsistent, and 9 pairs of pistons 3 of piston bush have the effect of a support, even after piston 3 aging the following the string, under the support of piston bush 9, also can be attached to the pump housing 4 inwalls well, prevents to leak.
In the present embodiment; Said water valve 6 comprises valve nozzle 61, water inlet body 62, silica gel valve 63, spool 64 and nozzle 65; Said valve nozzle 61 is connected with water inlet 7 through water inlet body 62; Said spool 64 is located in the silica gel valve 63, and is located at together in the nozzle 65, and said nozzle 65 is connected with delivery port 8.
