Intensity, on the other hand avoids screw to be bored a hole by reserving liquid tank during installing, affects the structural strength that casing is overall.
This utility model is further arranged to: be additionally provided with the glue for bonding between described fin inwall and memory foam block
Water layer.
By technique scheme, it is relatively stable that glue layer can allow memory foam block installs, and difficult drop-off, cost is relatively
Low.
This utility model is further arranged to: described fin vertically extends, and is parallel to each other between described fin.
By technique scheme, the fin vertically extended is squeezed and can expand toward both sides, improves the shape of backrest
Degeneration, it is ensured that the soft comfortable of backrest.
This utility model is further arranged to: described fin rectangular in shape.
By technique scheme, rectangular structure have can deformation behavior, can deformation in the case of being squeezed
Fit closely in the back making backrest and people, it is ensured that the stickiness of backrest.
This utility model is further arranged to: for being provided with 3 screws on described backrest, and two screws are distributed under backrest
The both sides at edge, another one screw is positioned against the centre position at back edge.
By technique scheme, the structure of screw is relatively simple, and backrest installs more convenient.And the screw of three
Quantity, it is possible to allow on the basis of fixing, the quantity of screw is preferably minimized.The structure that three screws are so distributed, it is possible to ensure
There is the situation of double swerve in backrest, and people are on foot when, and backrest is difficult to skew occur.
This utility model is further arranged to: described reserving liquid tank side is provided with mounting groove, and described rubber blanket plugs together to be installed
In groove.
By technique scheme, rubber blanket is wrapped up by outside backrest, is completed the peace of rubber blanket after plugging together entrance
Dress is fixing, the when of needing to change, is taken apart by backrest, then firmly peels off and just can complete, its mounting groove and rubber padding
The structure closed is easy to dismounting and the replacing of rubber blanket.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As it is shown in figure 1, a kind of knapsack sprayer, including reserving liquid tank 1, spray boom, the bottom of reserving liquid tank 1 be provided with battery and
The pump machine that battery connects, motor can drive pump machine to be sprayed toward outside by internal liquid.Its reserving liquid tank 1 is provided above with accordingly
Braces, described reserving liquid tank 1 is provided with backrest 2 near the side of human body
Wherein, backrest 2 is fixed on reserving liquid tank 1 by screw 22, for being provided with 3 screws 22, and two screws on backrest 2
22 both sides being distributed in backrest 2 lower limb, another one screw 22 is positioned at the centre position of backrest 2 top edge.The knot of screw 22
Structure is relatively simple, and backrest 2 installs more convenient.And screw 22 quantity of three, it is possible to allow on the basis of fixing, by screw
The quantity of 22 is preferably minimized.The structure that three screws 22 are so distributed, it is possible to ensure that the situation of double swerve, people occurs in backrest 2
On foot when, backrest 2 be difficult to occur skew.
Further, backrest 2 is provided with a plurality of fin 21, and fin 21 vertically extends, and is parallel to each other between fin 21,
Fin 21 rectangular in shape, rectangular structure have can deformation behavior, can deformation make to lean in the case of being squeezed
Fit closely in the back of the body 2 and the back of people, it is ensured that the stickiness of backrest 2.
As in figure 2 it is shown, backrest 2 is made up of EVA material, the fin 21 on backrest 2 is internal engraved structure, fin 21 interior
Portion fills and is provided with memory foam block 23.EVA is the material after foaming, and people leans against backrest 2, and backrest 2 can be pressed by elasticity
Contracting, make that people feel more is comfortable.Memory foam is the polyetherurethane foam sponge with low resilience mechanical property,
Can slowly restore to the original state after being squeezed so that fin 21 shape on backrest 2 can effectively be recovered.Its bounce-back
Power is relatively low, human body relies on backrest 2 when, the most comfortable, and has certain breathability, hygroscopicity.Meanwhile, leaning on
It is additionally provided with rubber blanket 24, the buffering of rubber blanket 24, it is to avoid softer backrest 2 and harder reserving liquid tank between the back of the body 2 and reserving liquid tank 1
The directly contact of 1, and then further avoid expendable deformation during backrest 2 uses.
Backrest 2, memory foam block 23, rubber blanket 24 fixed structure on as in figure 2 it is shown, fin 21 inwall with memory sea
Utilizing one layer of glue layer being about 1 ~ 2mm 25 to fix between continuous block 23, glue layer 25 can bond memory foam block 23, makes
It does not haves and comes off.And fluid reservoir is arranged above with three mounting seats 11, mounting seat 11 and screw 22 one_to_one corresponding, each spiral shell
Nail 22 is inserted in mounting seat 11, and it connects degree of depth more deep, and then is that the fixing comparison of screw 22 is tight.And rubber blanket 24 is
Between backrest 2 and reserving liquid tank 1, reserving liquid tank 1 arranges mounting groove 12 near the side of backrest 2, and the shape of mounting groove 12 is
Keeping consistent with rubber blanket 24 structure, rubber blanket 24 plugs together inside mounting groove 12, and the thickness of rubber blanket 24 is than mounting groove 12
Want deep.Rubber blanket 24 is fixed when, side is the bottom land laminating with mounting groove 12, and opposite side is fitted with backrest 2,
And then allow rubber blanket 24 plug together inside mounting groove 12.
The above is only exemplary embodiment of the present utility model, not for limiting protection model of the present utility model
Enclosing, protection domain of the present utility model is determined by appended claim.
