Fig. 3 is the structural schematic diagram of breathable fabric.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding Few couple auxiliary, Lai Zucheng more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict Under the premise of can be with combination of interactions.
Embodiment 1, with reference to Fig. 1 and Fig. 2, a kind of sprayer, including tank body 1, the back of the tank body 1 are equipped with pull rod knot Structure, the Tiebar structure include: upper pole part 2, lower bar portion 3 and idler wheel 4, the fixed back for being located at the tank body 1 of lower bar portion 3 Portion, the upper pole part 2 include: two vertical bars 21, and two vertical bars 21 are parallel to each other, and the upper end of two vertical bars 21 passes through The connection of one cross bar 22, the lower end of two vertical bars 21 passes through hinge joint and the upper end of lower bar portion 3 is hinged, the lower bar portion 3 Equipped with the holding tank 31 for accommodating upper pole part 2, the upper pole part 2 can fold into holding tank 31 along hinge joint 32, under described The lower end of bar portion 3 extends to the back edge of tank body 1, and the idler wheel 4 is mounted on the lower end of the lower bar portion 3.Wherein, on described Bar portion 2 and lower bar portion 3 are light plastic material, can reduce the weight of sprayer.
The front of the tank body 1 is equipped with shoulder harness structure, and the shoulder harness structure includes shoulder belt ontology 8, and the shoulder belt ontology 8 wraps Outer layer 81 and inner layer 82, the outer layer 81 and the overlapping connection of inner layer 82 are included, it is empty to form interlayer between the outer layer 81 and inner layer 82 Between 83, be equipped with liquid storage pipe 84 in the interlayer space 83, the liquid for cooling, the liquid storage store in the liquid storage pipe 84 The distribution in the form of a serpentine of pipe 84, the outer layer 81 and inner layer 82 are made of gas permeability fabric.
When operating personnel needs to shift disinfection place, it is only necessary to put down tank body 1, by upper pole part 2 from accommodation groove 31 It folds out, by the idler wheel 4 of lower 3 lower end of bar portion, operating personnel can haul sprayer movement by upper pole part 2, very convenient. Meanwhile when operating personnel carries sprayer operation, the heat of body is transmitted in interlayer space 83 by inner layer 82, due to storage Store the liquid for cooling in liquid pipe 84, therefore, heat is by the liquid absorption in liquid storage pipe 84, to help operating personnel Extra heat is discharged in time, so that operating personnel feels very comfortable when wearing shoulder belt.
Embodiment 2, as advanced optimizing for embodiment 1, on the basis of embodiment 1, the cross bar 22, which is covered with, to rub Wipe layer.The frictional force between operating personnel and upper pole part can be increased by frictional layer.
Embodiment 3, with reference to Fig. 3, as advanced optimizing for embodiment 1, on the basis of embodiment 1, the gas permeability Fabric includes: upper layer 811 and lower layer 812, and the upper layer 811 is formed by polypropylene fiber with the structure textile of warp and weft and shape At there is upper air hole 8111, lower layer 812 is warp by nylon fibre and spandex fibre is that weft blending woven is formed and is formed with Lower air hole 8121, upper air hole 8111 and lower ventilative 121 holes are oppositely arranged, and absorbing sweat is equipped between upper layer 811 and lower layer 812 Layer 813, the sweat-absorbing layer 813 are high moisture absorption fiber.The high moisture absorption fiber is that can absorb gas phase under the conditions of standard atmosphere Moisture, fiber of the regain 6% or more.
The upper layer 811 of gas permeability fabric is formed by weaving by polypropylene fiber, and lower layer 812 is that warp and spandex are fine by nylon fibre Dimension is that weft blending woven forms, and well combines polypropylene fiber, nylon fibre, three kinds of spandex fibre different types of line kinds Together, the fabric obtained has both the characteristics of polypropylene fiber, nylon fibre, spandex fibre, make it have scratch resistance, flexibility it is good, Wrinkle resistance is strong, good permeability, comfortable advantage of cooling off oneself.The upper air hole 8111 and lower air hole 8121 being oppositely arranged, can guarantee Airflow, so that cooling effect is more preferably.
