Embodiment
Referring to figs. 1 through Fig. 5, a kind of knapsack sprayer embodiment of the utility model is described further.
Braces 2 is fixed on the lateral wall of liquid storing barrel 1, liquid storing barrel 1 is provided with the air blowing portion 3 towards braces 2 direction blow gas, the outer barrel wall of described liquid storing barrel 1 is also provided with the source of the gas portion 4 be conducted with air blowing portion 3, described source of the gas portion 4 comprises stripper plate 41 and bellows 42, described stripper plate 41 is hinged with the diapire of liquid storing barrel 1, stripper plate 41 can along jointed shaft swing, the plane orthogonal that jointed shaft and operator's thigh swing, the two ends of bellows 42 are sealedly attached on the sidewall of stripper plate 41 and the outer barrel wall of liquid storing barrel 1 respectively, one end away from liquid storing barrel 1 of described stripper plate 41 is provided with the contact part 5 of conflicting with operator's thigh, by operator's thigh extruding contact part 5, stripper plate 41 can around jointed shaft extruding bellows 42, because existing knapsack sprayer carries on the back back in operator by braces 2, stripper plate 41 is hinged with the diapire of liquid storing barrel 1, when reality uses sprayer, operator's somagenic need constantly moves forward and backward, in this process, the thigh of operator can constantly be conflicted with contact part 5, thus stripper plate 41 is constantly swung around jointed shaft, whole stripper plate 41 will extrude bellows 42 incessantly, when the tube chamber of bellows 42 be squeezed plate 41 effect and diminish time, source of the gas portion 4 and air blowing portion 3 are conducted, gas in bellows 42 is just direct to be blown out from air blowing portion 3, this gas directly rushes at braces 2 direction, now just can give human body back radiating and cooling effect, when the thigh of operator lifts forward, would not conflict with operator's thigh in contact part 5, the Action of Gravity Field of stripper plate 41 self down will rotate around jointed shaft, now the tube chamber of bellows 42 will become large, while change is large, air will be inhaled into from air blowing portion 3, just complete the process of air-breathing and exhaust and so forth, the back of operator also can obtain radiating and cooling in air-breathing and exhaust process.
Back-moving spring 6 is connected with between the side of stripper plate 41 and the diapire of liquid storing barrel 1, in use in a lot of situation, the step translational speed of user is very fast, there will be the situation that thigh gets to stripper plate 41, arranging of back-moving spring 6 can make whole stripper plate 41 energy Rapid reset, and in the process of movement fast, whole air blowing process also can be followed to get up fast, the outgassing rate in air blowing portion 3 is accelerated, and radiating and cooling speed obviously promotes.
The face that liquid storing barrel 1 contacts with human body back forms installed surface 7, described air blowing portion 3 is positioned on installed surface 7, described air blowing portion 3 comprises the air blowing plate 31 of hollow, described air blowing plate 31 is provided with some gas holes 32 near the sidewall of human body back, described gas hole 32, air blowing plate 31, source of the gas portion 4 conducting successively, the air blowing plate 31 of hollow is arranged several gas holes 32, can effectively increase air blowing area, the air blowing plate 31 of hollow also can alleviate the weight of self of whole sprayer to a certain extent, what alleviate user bears burden, saves physical demands.
Breather pipe 8 is connected with between air blowing plate 31 and bellows 42 tube chamber, unidirectional air outlet valve 10 is provided with in described breather pipe 8, described stripper plate 41 is provided with breather cheek valve 9, the arranging of unidirectional air outlet valve 10 and breather cheek valve 9 can make air inlet and the position of giving vent to anger reasonably be configured, when unidirectional air outlet valve 10 and breather cheek valve 9 are not set, air inlet and give vent to anger and all concentrate in air blowing portion 3, the clothes of user will be caused like this to be attracted in air blowing portion 3, cause to a certain extent and cannot fully dispel the heat, and when breather cheek valve 9 is arranged on stripper plate 41, and unidirectional air outlet valve 10 is when being arranged in the breather pipe 8 between air blowing plate 31 and source of the gas portion 4, whole gas will enter from stripper plate 41, avoid and to give vent to anger and air inlet all concentrates on problem in air blowing portion 3.
One end away from liquid storing barrel 1 of stripper plate 41 is provided with the contact part 5 of conflicting with operator's thigh, contact part 5 comprises cylinder 51, described cylinder 51 is positioned at stripper plate 41 one end away from liquid storing barrel 1, the lateral wall of described cylinder 51 is provided with rubber wrappage 52, in operating process, the thigh of operator can contact repeatedly with stripper plate 41 one end away from liquid storing barrel 1, can roll cylinder 51 can effectively less operator conflict process in frictional force, rubber wrappage 52 can reduce the foreign body sensation when thigh of operator and cylinder 51 are conflicted greatly, increase the comfort level in whole device use procedure.
Back-moving spring 6 is provided with 2,2 back-moving springs 6 are symmetrically distributed in the left and right sides of stripper plate 41,2 back-moving springs 6 can pull whole stripper plate 41 to move more effectively, the back-moving spring 6 of the left and right sides can increase stability when pulling, because the stability of rocking process improves greatly, also promote the whole service life of stripper plate 41 further.
In specific implementation process, when the back operator carried on the back by sprayer, when a thigh of operator is toward pusher, the cylinder 51 of thigh directly and on stripper plate 41 of operator is directly conflicted, now stripper plate 41 swings around jointed shaft backward, back-moving spring 6 is now in extended state, stripper plate 41 can extrude bellows 42, space in bellows 42 can reduce thereupon, air in bellows 42 will enter breather pipe 8 by unidirectional air outlet valve 10, air will enter in the cavity of air blowing plate 31 afterwards, air will be gone out from the gas hole 32 of air blowing plate 31, directly rush at the back of operator.
When a thigh of operator is lifted forward, stripper plate 41 is subject to the pulling force effect of back-moving spring 6, stripper plate 41 will toward forward swing, space in bellows 42 just has the trend of increase, now air will enter in bellows 42 from the breather cheek valve 9 of stripper plate 41, thus achieves the process of reciprocal air-breathing venting.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
