Ventilating fan of the present utility model is described with reference to the accompanying drawings in further detail.
With reference to accompanying drawing, ventilating fan of the present utility model mainly comprises motor 7, flabellum 5, spiral case 3, shell 8 and exhaust outlet 12, panel 24, it is characterized in that, described motor 7 is fixed on the spiral case lid 6, motor 7 is connected with flabellum 5 by motor drive shaft, spiral case lid 6 is fixed on a side of spiral case 3, the spiral case 3 that flabellum 5 and motor 7 are housed is by right fixed plate 1, left side fixed plate 2, back poppet 4 is fixed in the shell 8, is furnished with panel 24 on the shell 8, exhaust outlet 12, support 17, base plate 9, is furnished with main air tongue 13 on the exhaust outlet 12, secondary wind tongue 15 and guide vane 14, extension spring 25 is fixed in the top that spiral case covers entire machine with panel 24.
As shown in Figure 5, motor 7 is fixed on the spiral case lid 6 by screw 21, successively motor jump ring 20, flabellum fixed plate 19, flabellum 5 are placed on the motor drive shaft of motor 7, then with nut with on their fixing motor axles, on spiral case 3, spiral case 3 can be with the grab of self band with spiral case location and fixing simultaneously by screw for spiral case lid 6.With left fixed plate 2, right fixed plate 1 and the back poppet 4 of spiral case shown in Figure 23 by positioning and fixing on the internal surface of shell shown in Figure 38, left side fixed plate 2, right fixed plate 1 and back poppet 4 can be weldingly fixed on the internal surface of shell 8 then respectively by the positioning hole location.
As shown in Figure 2, be furnished with on the spiral case 3 in electric lid plate 27, after circuit connects, with interior electric lid plate 27 by screw cover on interior electric box.
Spiral case 3 by grab or screw on the left fixed plate 2, right fixed plate 1 and the back poppet 4 that are fixed on the shell 8.The spiral case that motor and flabellum so just will be housed is installed in the shell.About being connected of left fixed plate 2, right fixed plate 1 and back poppet 4 and spiral case 3, shown in 8, can be connected and fixed with the square hole clamping of left fixed plate 2, right fixed plate 1 and back poppet 4 or by screw respectively by the grab that spiral case 3 carries.Existing ventilating fan all is that spiral case 3 is fixed on the base plate 9 of shell 8, and the application's ventilating fan moves left fixed plate 2, right fixed plate 1 and back poppet 4 on the whole, and is convenient like this in operator's installation and removal.
Then, as shown in Figure 3, the panel 24 of shell 8 is covered on shell 8 by extension spring 25.The upper end of extension spring 25 is an arc, and the lower end is a straight line, and design is in order to disassemble panel more easily like this, and does not injure human body.In addition, as shown in Figure 2, the screw 26 on the spiral case 3 can be used for fixing panel or fastening lampshades or fixing PTC overcoat, brings convenience for adding other function to ventilating fan later on like this.The bottom that exerts pressure for then the base plate 9 of shell 8 to make shell 8 is stuck in the groove of base plate 9 and is fixed together.
As shown in Figure 6, exhaust outlet 12 is connected with spiral case 8 by exhaust outlet fixed plate 10, and exhaust outlet 12 can be fixed on the exhaust outlet fixed plate 10 by spot welding, exhaust outlet fixed plate 10 by self grab and shell 8 on square hole fix or pass through screw.Be furnished with support 17 on the exhaust outlet fixed plate 10, the two can connect by spot welding.
Described ventilating fan comprises that also 11,16, two electric boxes 11,16 of two electric boxes are separately fixed at the left both sides of exhaust outlet fixed plate 10, and they are fixed on the exhaust outlet fixed plate 10 by spot welding respectively.
Can insert female fixed strip 22 shown in Figure 7 and sub-fixed strip 23 in the support 17, the width of sub-fixed strip 23 is less than or equal to the insied width of the groove of female fixed strip 22, and so fixed strip 23 can be through in female fixed strip 22.The primary and secondary fixed strip can insert from the left and right sides both direction of support 17, and they can insert simultaneously, also can insert one earlier, insert another again.According to the needs of erecting bed, determine the insertion depth of two fixed strips, reach the purpose of quick mounting, and the aperture for screw is arranged on female fixed strip 22 and the sub-fixed strip 23.Use two such fixed strips can increase the intensity of product.
As shown in Figure 6, the application's ventilating fan is furnished with main air tongue 13, secondary wind tongue 15 and guide vane 14.Main air tongue 13 put into the hole of the cylinder of exhaust outlet 12 from tape spool, guide vane 14 is fixed on the grab of main air tongue 13, main air tongue 13 realizes that by axle that carries and the hole that secondary wind tongue 15 carries the axis hole cooperation is connected.Because the material of guide vane 14 is a metal, the weight of the main air tongue 13 that weight is made greater than plastic materials, therefore, when calm, because of guide vane 14 gravity concern that nature is sagging, and guide vane 14 is near the inside of ventilating fans, thereby the main air tongue keeps vertical state when calm, seal exhaust outlet, when the outside has wind direction ventilating fan the inside to be blown into, can play the effect that stops.When outside ventilation fan has wind direction, blowing out,, the wind of ventilation fan the inside is outwards flowed better because the dynamic action of wind makes main air tongue 13 and secondary wind tongue 15 open wide to both sides respectively.
