Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with embodiment.
Fig. 1-4,6,7 are the structural schematic diagram of the utility model first embodiment, the fan body including wind speed is adjusted,
It further include being connected to fan body to compress door 1 towards the air in the one side of human body, it includes compression capping that air, which compresses door 1,
101 and compression caping 102, compression capping 101 be arc, the rounded face plate structure protruded to human body direction, compression capping 101
Side is connected with the compression caping 102 extended to fan body, and compression capping 101 and compression caping 102 are in integral structure, can also
It is pasted together with fixation, compression capping 101 and compression caping 102 are formed together and cover fan body close to human body one side
Structure makes one side of the fan body towards human body compress door 1 with air and forms cavity, the gas of human body is blowed to by fan body
In into cavity and by primary compression, be distributed on compression capping 101 several rounded array distributions, perpendicular to compression
The surface of capping 101 and the open-work 4 for running through compression capping 101, the diameter of each open-work 4 gradually subtract from inlet end to outlet side
It is small, human body is blown to by open-work 4 by the gas of primary compression in the cavity, gas is when by each open-work 4 since open-work 4 is entered the wind
The diameter at end is greater than the diameter of 4 outlet air end of open-work, and gas is further compressed and expands rapidly when flowing out open-work 4, absorbs saturating
Heat on the outside of 4 outlet side of hole makes one body-sensing to feeling nice and cool, gas passes through twice so that blowing to the air themperature of human body reduces
The flow velocity of air-flow not only can be improved in compression, moreover it is possible to obtained when gas flows out 4 outlet side of open-work with outside 4 outlet side of open-work
The bigger pressure difference of the air in portion improves the speed of expansion of compressed gas, increases the heat of the absorption in expansion process, so that blowing to
The gas temperature of human body is lower, and cooling effect is more preferable.
In view of the length of open-work 4 is shorter, time of open-work 4 is flowed through in order to extend gas to extend gas compression processes,
The helical airflow passages 401 of the length direction extension along each open-work 4, spiral air flow are offered on the side wall of each open-work 4
401 pairs of the channel gas for entering each 4 inner wall of open-work plays the role of water conservancy diversion, extends gas compressed time in open-work 4, reaches
To better cooling effect, and cause to make gas can smoothly enter into open-work 4 and reduce shock open-work 4 when gas reaches inlet end
Flow velocity reduces, and cuts off face 402 for arc is arranged at the inlet end of each open-work 4, and gas is sent out when in order to enable to flow out each open-work 4
It scatters and blows to human body all directions, cut off face 402 for arc is arranged at the outlet side of each open-work 4.
Compressing caping 102 is that relaxing when human contact compresses caping 102 both can be improved to the arcuate structure of outside protrusion
Appropriateness can also increase the storage of air in the cavity for flowing to and being formed by fan body, compression capping 101, compression caping 102
Amount, it is contemplated that during then flowing into open-work 4 by cavity by the gas of fan body blowout, blown to improve by fan body
Gas out enters the speed of cavity and enhances cooling effect, offers plurality of guiding gutter on the inner wall of compression caping 102
103, each diversion trench 103 runs through the inner wall of compression caping 102, and radial direction along the length direction of compression caping 102
The direction setting of capping 101 is compressed, each diversion trench 103 is evenly distributed on the inner wall of compression caping 102, diversion trench 103103
Setting improve the flowing velocity that gas enters open-work 4 through cavity.
In order to further increase cooling efficiency, it can be fixed on the cell wall of part diversion trench 103 and paste small-sized phase transformation cooling
Bag 5 is placed with Na inside each phase transformation cooling bag 52SO4Crystalline hydrate absorbs the heat of inner using phase transformation cooling bag 5,
The radiating efficiency for further increasing human body simultaneously flows through the partial heat in the gas of phase transformation cooling bag 5 by Na2SO4Crystalline hydrate
Object absorbs, and the temperature for blowing to the gas of human body is further decreased, while in view of the utility model is for clothes cooling, in order to make
Human body feels comfortable, and compression capping 101 is made with compression caping 102 of elastic material, such as rubber or silica gel, compresses caping
102 one end far from the compression capping 101 are equipped with cyclic annular retainer ring 6, and compression caping 102 is fixed to be pasted onto the outer of cyclic annular retainer ring 6
On circumferential surface, cyclic annular retainer ring 6 is internally recessed far from the one side of compression caping 102 and forms the slot that can accommodate fan body shell
Shape structure, 6 fixing sleeve of annular collar can dismantle annular collar 6 to come, annular snap in the shell exterior of fan body when needing
Circle 6 can be made of material such as rubber identical with compression caping 102, can also be made with material plastic.
Fig. 1,2,3,5 be the utility model second embodiment, the present embodiment the difference from the first embodiment is that, respectively
Open-work 4 is not the surface for extending vertically through compression capping 101, and the side for being directed towards compression cover face 101 is radial, favours pressure
The surface of contracting capping 101 can increase the covering surface for blowing to the lower gas of temperature on human body through compression capping 101 in this way
Product, improves the cooling efficiency of the utility model, can also reduce the quantity for being mounted on fan on clothes, economize on resources, and mitigates clothes
Fill whole weight.
The utility model with can be used cooperatively with a plurality of types of fan bodies, and pass through the adjustable wind of fan body
Speed, and then adjust the temperature for blowing to gas on human body.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
