The working principle and beneficial effect of the present embodiment are as follows:

The present embodiment avoids having gap between each Fan spray head, when spray can produce by the way that squarely is arranged in spout 16-5 Life and death angle influences the effect of effect product sterilization sterilizing；Meanwhile spout 16-5 being arranged on mounting blocks 16-2, and spout 16-5 is logical The cooperation for crossing the spherical turn trough 16-3 of the first spherical shape switch block 16-4 and mounting blocks 16-2 upper first can rotate, and adjustment is facilitated to spray to Angle further avoids leading to the problem of dead angle when spray；Furthermore by the way that the second spherical turn trough 16- is arranged in fixed block 16-11 The 12 and second spherical switch block 16-13, and it is equipped with that multiple diameters are different and and third channel in the second spherical switch block 16-13 The corresponding flow liquid channel 16-14 of 16-15 rotates the bull stick 16-17 band in turn trough 16-16 when needing to adjust spray uninterrupted Dynamic second spherical shape switch block 16-13 is rotated in the second spherical turn trough 16-12, when corresponding flow liquid channel 16-14 and third channel 16-15 to it is corresponding when then may be implemented spray disinfecting action, therefore the different flow liquid channel 16-14 of multiple diameters facilitates behaviour Make adjusting of the personnel to spray uninterrupted.

The present embodiment has the beneficial effect that, improves the effect of spray, while in spray, disinfection and sterilization medicament is added, Can effectively reduce malt takes bacterium number amount, guarantees safe and healthy.

As shown in Figure 10, in one embodiment,

It is equipped with regulation pipe 17-1 in the water-supply-pipe 17, is equipped in the water-supply-pipe 17 around the outer peripheral edge regulation pipe 17-1 Anti-shake ring 17-3, only cushion rubber ring 17-2 and sealing rubber ring 17-4, the anti-shake ring 17-3 are located at the top of only cushion rubber ring 17-2, institute The lower section that sealing rubber ring 17-4 is located at only cushion rubber ring 17-2 is stated, is equipped with snap close piece 17-5, institute on the outside of the lower section of the water-supply-pipe 17 Stating snap close piece 17-5 includes the first lock ring 17-6 and the second lock ring 17-7 and the vertical connecting rod connecting with sealing rubber ring 17-4 17-8, the first lock ring 17-6 and the second lock ring 17-7 are fixed by bolt 17-9 cooperation, and the first lock ring 17-6 is located at the second lock ring The top of 17-7 and the lower section outside for being fixed at water-supply-pipe 17, the lower end of the regulation pipe 17-1 is connected by Coupling 17-10 Connect the spray head 16.

The anti-shake ring around regulation pipe outer peripheral edge, only cushion rubber ring and sealing rubber ring are additionally provided in the sag pipe.It is described close The diameter of sealing rubber ring be 7.5-8mm, and be located at anti-shake ring lower section, and only cushion rubber ring with a thickness of 2mm.Anti-shake ring, only cushion rubber There is gap between ring and sag pipe, anti-shake ring plays the role of preventing swaying.

It can be matched by regulation pipe after the distance that sagging in-pipe is suitble to by the first lock ring and the second lock ring and bolt Stationary positioned regulation pipe is closed, sealing rubber ring seals the junction of regulation pipe and sag pipe under the drive of vertical connecting rod, prevents Leak occurs.In addition, adjusting telescopic extensions of the regulation pipe in sag pipe are 30-50mm, general difference can satisfy Height requirement avoids occurring in the recessed furred ceiling of spray head, so that furred ceiling unsightly and is coordinated very much, reduces the case where fitting up effect Occur.

The lower end of the regulation pipe and the upper section of spray head are respectively screw the upper and lower ends for being connected to Coupling, facilitate spiral Disassembly replacement.

The present embodiment, so that can adjust at a distance from malt according to actual needs, is had reached by the up and down adjustment of spray head Preferably it is sprayed effect.

As shown in Figure 11 to Figure 13, in one embodiment, the spray head 16, comprising:

Head body 100 has the bucket body structure of water inlet, and 101 court of bucket bottom of the bucket body structure for a upper end Protrusion 202 is arc outward；Water guide body 102 is helical form sheet body structure, outside the helical form of the water guide body 102 Side forms helical form between water guide body 102 and the inner sidewall of bucket body structure along 100 inner sidewall of head body is fixed at Intake tunnel；Multiple first apopores 103, are evenly distributed in column on the side wall of bucket body structure, and multiple first apopores 103 are connected to setting with intake tunnel；

Block sleeve comprising multiple sides are along the plugging sheet 201 for being mutually spliced into circular cylinder body, multiple plugging sheets 201 Upper end pivot joint the upper end of head body 100 is set, the lower end of multiple plugging sheets 201 extends to the lower end of head body 100 Setting, so that the inner sidewall conflict of multiple plugging sheets 201 is arranged on the lateral wall of head body 100；Multiple raised 202, It is provided projectingly on the inner sidewall of multiple plugging sheets 201, and multiple raised 202 is one-to-one with multiple first apopores 103 Arranged in rows, multiple raised 202 are removably embedded in multiple first apopores 103；Water guiding groove 203, embedded setting On the inner sidewall of multiple plugging sheets 201, and it is arranged between multiple raised the 202 of two adjacent column；Multiple plugging sheets 201 Free end is fixed on the lateral wall of head body 100 by the sealing of magnet 303；And

Cap body 300, on the lower end that be located in head body 100, and the cap body 300 includes multiple work being arranged alternately Dynamic page 301 and fixed page 302, any one active page 301 and any one fixed page 302 are from the periphery of cap body 300 to cap body The extended arc triangle shape metal sheet in 300 center, and multiple active pages 301 being arranged alternately and fixed page 302 Tip extends to the center of cap body 300 and contradicts setting；Active page 301 and the periphery of cap body 300, which are pivotally connected, to be arranged, and active page 301 tip is fixedly connected with setting with the tip of fixed page 302 by magnet 303；Multiple second apopores 104, setting exist On the section bottom of the bucket body structure of face active page 301.

In the above scheme, the water stream channel of spiral is formed between water guide body 102 and the side wall of head body 100, no Water (flow) direction only can be effectively guided, concentrates it to water outlet hole site, and can also be under existing hydraulic condition, in spray head sheet 100 position of body again promotes hydraulic pressure, and then improves the range that water is sprayed from water outlet, improves the effective range of hydro-peening；

In idle situation, plugging sheet 201 is kowtowed on the lateral wall for setting and being fixed on head body 100, multiple protrusions 202 it is embedded go deep into the first apopore 103, plugging sheet 201 can be assisted to limit the water of 100 inner cavity of head body, Compact mechanical structure, will not there is a situation where overflow；

After connecting water source, in the presence of hydraulic pressure, bottom surface Unscrew of the active page 301 relative to head body 100, Multiple plugging sheets 201 are rotated also relative to the side wall of head body 100 and are opened, and water is from multiple first apopores 103 and multiple the Two apopores 104 spray；It, can be one since plugging sheet 201 has certain weight when water is sprayed from the first apopore 103 The spray regime for determining the water that limitation sprays in range, will not spray directly up.

The projected area of the present embodiment spray head is big, range is long, penetration power is strong, cleaning ability is strong, is can satisfy completely to wheat The flushing of bud needs.

It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
