Abstract
The utility model relates to a ventilating safety working cap, comprising a cap body, a miniature electric fan, switches and a dry cell box. The utility model is characterized in that a fan chamber special for containing the miniature electric fan, the switches and the dry cell box is arranged at one end inside of the cap body; the miniature electric fan, the switches and the dry cell box are combined to form an electric fan component; the electric fan component is fixed on the fixed seat in the fan chamber through the connecting lugs which are arranged at two sides of the dry cell box. In the utility model, the protecting cap has ventilative function, and the integrity of cap body isn't damaged at all to ensure that the ventilating safety working cap has rigid intensity; the impact of the heavy object can be endured to protect the safety of wearers. The utility model has the advantages of beautiful appearance, and convenient manufacture.
Description
The utility model is about safety cap, particularly about having the safety cap of ventilation unit.
Patent Office of the People's Republic of China discloses the patent application of " helmet with gentle breeze fan and visor automatic cleaning apparatus " (application number 88217422.3) in July, 1989.Though this patent application has improved the ventilation condition of the helmet, structure is too complicated, and manufacturing is inconvenient, cost is high.May 23 nineteen ninety, the patent application that Patent Office of the People's Republic of China discloses again a kind of " safety cap of band fan " (application number 89209436.2, notification number CN2057316U).It is the minitype motor driving fan blade blowing that utilizes directly over being arranged in the safety cap.Micromachine is to be fixed on cap body top with brace rod, and dry cell is fixed on cap body rear outside, and several fresh air inlets are opened at cap body top also along continuous straight runs, though this kind safety cap does not change original safety cap structure, so easily manufactured.But the space between cap body and the cap liner is too small; do not hold micromachine; so need at the safety cap top drilling; the part fuselage of micromachine is exposed outside safety cap; this has just weakened the strength and stiffness of safety cap; easily distortion even destruction under heavy burden is impacted do not have due protective effect, cause injury on the contrary.In addition, micromachine and dry cell are exposed to the outer damage that subjects to.
The purpose of this utility model is to provide a kind of globality and original impact strength that keeps the cap body, does not make micromachine and dry cell be exposed to the outer interior ventilation safety working cap of cap again.
The purpose of this utility model is achieved in that a kind of interior ventilation safety working cap that comprises cap body, mini fan, switch and dry cell box, the inside that it is characterized in that cap body one end is provided with fan room, be provided with the holder of dry cell box in the fan room, micro machine is fixed on dry cell box top.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model front elevational schematic.
Fig. 2 is the schematic top plan view of Fig. 1.
Fig. 3 is that A-A analyses and observe the amplification signal.
Fig. 4 is that K is to view (amplification).
Fig. 5 is the electric fan assembly
Fig. 6 is the side-looking signal of Fig. 5.
Surface structure of the present utility model as depicted in figs. 1 and 2.Cap body 1 both sides are provided with the reinforcement 2 of projection.One end of cap body is provided with a projection 3 sleekly.The interior space of projection 3 is the 6(Fig. 3 of fan room).Electric fan assembly 4 is installed in the fan room 6.Fan room 6 is provided with some air vents 5 and holder 7(Fig. 4).Holder 7 is provided with screw 9.Electric fan assembly 4 comprises micromachine 17, flabellum 10, switch 16 and dry cell box 13(referring to Fig. 4 and Fig. 5).Flabellum 10 is fixed on the output axle head of micromachine 17 and constitutes mini fan.Micromachine 17 usefulness screws 12 are fixed on dry cell box 13 tops.Dry cell box 13 5 face closures, we opens one side, and its two sides are provided with engaging lug 14.Switch 16 is arranged on the below of dry cell box 13.Dry cell box 13 tops also can be provided with the seat hole 11 of extension, and micromachine 17 places in the hole 11, to strengthen the steadiness that micromachine 17 connects.Engaging lug 14 is provided with unthreaded hole 19.Hold-down screw passes the screw 9 that unthreaded hole 19 is screwed into holder 7, and electric fan assembly 4 is fixed in the fan room 6.Engaging lug 14 also can be provided with upwardly extending plug tenon 18, then is correspondingly provided with slot 8 on the holder 7.Plug tenon 18 is inserted in the slot 8, to strengthen the steadiness that electric fan assembly 4 is installed.
The utility model can be provided with supply socket 13(Fig. 5 below dry cell box 13).So that when using chargeable dry cell, the usefulness of charging.
The utility model makes safety cap increase aeration-cooling function, has improved user's condition of work, and does not reduce the strength and stiffness of safety cap at all.Particularly additional zero such as mini fan and dry cell parts all are positioned at the ad hoc space of safety cap, have not only protected equipment itself, and have protected user's safety itself.
