Abstract

Disclosed is a sprayer switch comprising a switch controlling valve, a spraying pipe with a nozzle connected hermetically with a port of the switch controlling valve and a rotatable pressing handle whose lower surface is arranged with a projection. The sprayer switch is characterized in that the sprayer switch further comprises an upper shell body and a lower shell body, the switch controlling valve is arranged in a room limited by the upper shell body and the lower shell body, and the pressing handle can be spirally arranged on the rear end of the outer portion of the shell body, the projection of the lower surface of the pressing handle can be inserted into a hole of the shell body and can press a valve spool of the switch controlling valve. Compared with the prior sprayer switch, the utility model has simple structure and lower manufactures cost. Furthermore, all parts of the sprayer switch are made from plastic, once the valve body and the valve spool are eroded or the valve body is blocked by the dried mucus, just to change one-off switch controlling valve, thereby the operating is simple and the cost can be further reduced.

Description

Sprayer switch

Technical field

The utility model relates to a kind of sprinkling gauge tap that is used for sprayer.

Background technology

In daily life, people with sprayer liquid such as be used to spray insecticide, for the ease of operating light realization crawl and continuous operation, need to use the sprayer with gauge tap through regular meeting.

Chinese patent ZL03229725.4 discloses a kind of sprayer switch.The spool of this sprayer switch is installed on the valve core, by being installed in the crawl of the pressure handle control spool realization spraying on the valve core, utilizes the eccentric block locking pressure handle of front end simultaneously, makes sprayer switch be in continuous atomize.This sprayer switch is easy to use, and is laborsaving, but complex structure, in addition, be used to spray chemical agent, corrosive liquids, viscosity bigger liquid the time, the mucus choke valve body that in a single day valve body and spool are corroded or become dry, will all change sprayer switch, cost is higher, causes waste.

Summary of the invention

The utility model will solve the baroque problem of existing sprayer switch, and a kind of sprayer switch cheaply simple in structure is provided.

For addressing the above problem, sprayer switch of the present utility model, comprise a switching control pilot, one a injection spray pipe that is connected with the exit seal ground of switching control pilot and a tube connector that is connected with the inlet seal ground of switching control pilot with a nozzle, one rotatable lower surface has the pressure handle of a projection, it is characterized in that, also comprise a upper shell, one lower house, switching control pilot is contained in indoor that upper shell and lower house limit, pressure handle is rotatably installed in the upper shell outer front end, and the projection of pressure handle lower surface can stretch into the spool of pressing switch control valve in the hole of upper shell.

Upper shell has a chute, and chute is positioned at below the pressure handle, and a slide block that is contained in the chute of upper shell exposes from a square hole of pressure handle, and slide block has an external part.

All parts of sprayer switch are made by plastics.

It is few, simple in structure that sprayer switch of the present utility model and existing sprayer switch are compared part, low cost of manufacture.

In addition, all parts of sprayer switch are made by plastics, the mucus choke valve body that in a single day valve body and spool are corroded or become dry, as long as change the disposable switch control valve, simple to operate, cost can further reduce.

Description of drawings

Engaging the drawings and specific embodiments below is described further sprayer switch of the present utility model.

Fig. 1 is the cross-sectional schematic of the utility model sprayer switch;

Fig. 2 is the perspective exploded pictorial view of sprayer switch shown in Figure 1.

The specific embodiment

The utility model sprayer switch 1 shown in Figure 1 comprises injection spray pipe 2, switching control pilot 3, upper shell 4, slide block 5, pressure handle 6, clip 7, tube connector 8, lower house 9 and nozzle 15.Nozzle 15 is connected by thread seal ground with an end of injection spray pipe 2.The other end of injection spray pipe 2 is connected by thread seal ground with the outlet of switching control pilot 3.One end of tube connector 8 is fixed in the import of switching control pilot 3 hermetically by clip 7.Slide block 5 is contained in the chute 14 of upper shell 4, can slide along chute 14.Slide block 5 has external part 16.Pressure handle 6 is installed on the cylinder axis of upper shell 4 both sides, can rotate up and down around cylinder axis.Upper shell 4 and lower house 9 are connected by buckle, and switching control pilot 3 is fixed on the indoor certain position that lower house limits.One hole 11 is arranged on the upper shell 4, and there is a projection 10 position corresponding with hole 11 on the lower surface of pressure handle 6, and projection 10 can stretch into hole 11, the spool of pressing switch control valve 3.Has square hole 12 on the pressure handle 6.

Spool and spring (not shown) are housed in the switching control pilot 3.Spring be positioned at spool below, spool is applied the elastic force effect.Spool can slide up and down sealedly at the housing of switching control pilot 3, opens or closes the outlet of switching control pilot 3.

All parts of sprayer switch are made by plastics.

The concrete operations of the utility model sprayer switch 1 are as follows:

Press pressure handle 6 downwards, the spool of the projection 10 downward pressing switch control valves 3 of pressure handle 6 is opened switching control pilot 3, slides backward the slide block 5 that the square hole 12 from the pressure handle 6 exposes, the external part 16 of slide block 5 is pressed on the upper surface of pressure handle 6, makes switching control pilot 3 stay open state.

Pressure handle 6 relative upper shells 4 are rotated up certain angle, the projection 10 of pressure handle 6 moves up, leave the spool of switching control pilot 3, the spool of switching control pilot 3 resets under the effect of spring, switching control pilot 3 is closed, slide backward the slide block 5 that the square hole 12 from the pressure handle 6 exposes, the external part 16 of slide block 5 is stretched between pressure handle 6 and the upper shell 4, make switching control pilot 3 keep closed conditions.

To remain on this position from the slide block 5 that the square hole on the pressure handle 6 12 exposes, and press downwards or upwards lift and change pressure handle 6, the spool of the projection 10 point driving switch control valves 3 of pressure handle 6 opens or closes 3 moments of switching control pilot, realizes that crawl sprays.

, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.

Claims (3)

1, a kind of sprayer switch, comprise that a switching control pilot, an injection spray pipe with a nozzle that is connected with the exit seal ground of switching control pilot and a tube connector that is connected with the inlet seal ground of switching control pilot, a rotatable lower surface have the pressure handle of a projection, it is characterized in that, also comprise a upper shell, a lower house, switching control pilot is contained in indoor that upper shell and lower house limit, pressure handle is rotatably installed in the upper shell outer front end, and the projection of pressure handle lower surface can stretch into the spool of pressing switch control valve in the hole of upper shell.

According to the described switch of claim 1, it is characterized in that 2, upper shell has a chute, chute is positioned at below the pressure handle, and a slide block that is contained in the chute of upper shell exposes from a square hole of pressure handle, and slide block has an external part.
