Abstract

A sprayer core comprises a core main body structure, an air chamber connected with the core main body structure; a gear rack drive mechanism composed of a gear and a rack and arranged on the core main body structure, wherein the end of the rack is connected with a piston and the piston is driven by the movement of the rack to reciprocate in a hand pump; an check valve between the core main body structure and the air chamber, wherein the hand pump of the core main body structure is unidirectionally communicated with the air chamber by an one-way valve. The spray core solves the problems of the prior sprayer and the sprayer core that the volume is large, the installation is complicated, loosening and gliding are generally generated while in use, the noise is larger and the safety hidden trouble is present. The sprayer core has features of compact structure, easy manufacture, small noise, safety and reliability and long life.

Description

A kind of sprayer movement

Technical field the utility model relates to a kind of sprayer movement, belongs to the agricultural atomizer product technical field.

The feed flow movement that background technology is used on sprayer at present all is to adopt linkage to drive piston to carry out the operation of pump liquid; it is big that the linkage of this structure exists volume; install complicated, use in when regular meeting produces loosening slippage and uses the bigger problem of noise; simultaneously because structure such as safety valve is not installed; the sprayer and the movements thereof of a large amount of uses of institute at present in fact also exist certain potential safety hazard; gently then the sprayer movement damages, and is heavy then may hurt the user of service.

Summary of the invention the utility model provides a kind of a kind of sprayer movement of novelty, adopts rack and pinion drive mechanism and one-way relief valves technology, realizes the purpose of sprayer and the safe and efficient use of movement thereof.

The technical solution adopted in the utility model is:

A kind of sprayer movement, comprise: movement main body structure, air chamber, air chamber is connected with the movement main body structure, in the movement main body structure rack and pinion drive mechanism by gear, tooth bar constituted is set, the end of tooth bar is connected with piston, the mobile drive piston of tooth bar is reciprocating in pump, is provided with check valve between movement main body structure and air chamber, and the pump that makes the movement main body structure is by check valve and the unidirectional conducting of air chamber.

Also be provided with tapping valve on the movement main body structure, tapping valve is positioned on the structure of movement main body structural plan, and the passage of tapping valve communicates with air chamber.

Also be provided with safety valve on the movement main body structure, safety valve is positioned at the pump tip position, and pump is by safety valve and the outside unidirectional conducting release of movement.

The utility model beneficial effect is:

Owing to adopted sprayer movement of the present utility model; solved and existed the movement volume bigger than normal on the existing sprayer; install complicated, use in when regular meeting produces loosening slippage and uses noise big and exist the problem of potential safety hazard, a kind of sprayer movement of the present utility model has: compact conformation, easy to manufacture, noise is little, safe and reliable and characteristics that the life-span is long.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3.

The sprayer movement by: movement main body structure 1, air chamber 2 are formed.

Movement main body structure 1 comprises: gear 11, tooth bar 12, tapping valve 13, safety valve 14, check valve 15, piston 16, pump 17 structures.

Air chamber 2 on the movement is connected with movement main body structure 1, movement main body structure 1 is provided with the rack and pinion drive mechanism that is made of gear 11, tooth bar 12, the end of tooth bar 12 is connected with piston 16, the mobile drive piston 16 of tooth bar 12 is reciprocating in pump 17, be provided with check valve 15 between movement main body structure 1 and air chamber 2, the pump 17 that makes movement main body structure 1 is by check valve 15 and air chamber 2 unidirectional conductings.

Be provided with tapping valve 13 on movement main body structure 1, tapping valve 13 is positioned on movement main body structure 1 planar structure, allows the passage of tapping valve 13 communicate with air chamber 2.

Also be provided with safety valve 14 on movement main body structure 1, be positioned at pump 17 tip positions, pump 17 is by the unidirectional conducting release of the outside realization of safety valve 14 and movement.

With sprayer movement such as Fig. 1, Fig. 2, structure shown in Figure 3 is assembled installation, when sprayer in use, rotate by hand lever driven gear 11, gear 11 rotating band carry-over bars 12 move up and down, thereby it is reciprocating in pump 17 to drive piston 16, the reciprocating motion of piston 16 in pump 17 just can realize the suction pumpdown of liquid, during normal operation, liquid is by piston 16, the suction pumpdown of pump 17 is realized the work to the external spraying sprinkling, and by the certain spraying spray pressure of air chamber 2 maintenances, when the spraying spray pressure descends, when being the pressure decline in the air chamber 2, pressure fluid in the pump 17 will be pushed check valve 15 open and inject liquid in air chamber 2, because air chamber 2 is to be enclosed construction, so pressure will rise immediately, return to service pressure, constant with the spraying spray pressure that keeps sprayer, in normal operation when fluid pressure is too high in the pump 17, safety valve 14 will be opened and carry out off-load, make pressure return to service pressure very soon, when liquid in the needs eliminating air chamber 2 or gas, as long as open tapping valve 13, can finish discharge opeing or exhaust, tighten tapping valve 13 after finishing and get final product.
