Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The present embodiment discloses a kind of dust control by ventilation ammeter box, as shown in figure 1, including housing 1, chamber door is hinged with housing 1
2, ammeter 3 is installed within the case 1.The top surface of housing 1 and bottom surface offer a vent window 4, and the hot-air inside housing 1 can
Exchanged to reduce the air themperature in housing 1 with outside air by vent window 4, be used on vent window 4 covered with Air Filter 5
Prevent the dust in outside air from entering inside housing 1.Square mounting hole 6, mounting hole 6 are offered on the two sides of housing 1
In may be inserted into the ventilating duct 7 for being rendered as rectangular tube.The size outline of mounting hole 6 is less than the size of ventilating duct 7, ventilating duct 7
Both ends are tip end 8 made of quality of rubber materials, and mounting hole 6 at tip end 8 from one is inserted, and the mounting hole 6 from another
Passing can be installed on ventilating duct 7 on housing 1, and the tip end 8 of ventilating duct 7 protrudes from housing 1.
As shown in Figure 2 and Figure 3, the upper end of ventilating duct 7 is hinged with made of two panels plastics and the dustproof sheet 9 of lighter weight, and two
Piece dustproof sheet 9 is linked together by lightweight anchor line (string) 16.Two sloping platforms 10 are additionally provided with ventilating duct 7, sloping platform 10 is to be bonded
In being provided with an inclined-plane on the rectangular tube of the inwall of ventilating duct 7.Dustproof sheet 9 is affected by gravity to be turned around its articulated position
It is dynamic, and sloping platform 10 can be fitted under static state.Annular groove 11 is offered on sloping platform 10, is provided with dustproof sheet 9
The ring rib 12 that can be coincide with annular groove 11, when dustproof sheet 9 fits in sloping platform 10, ring rib 12 can be with annular
Groove 11 is bonded to be impacted with preventing dust, steam in external environment from entering inside housing 1 to ammeter 3.In ventilating duct 7 also
The air-vent 13 connected with the inside of housing 1 is offered, air-vent 13 is on the inwall of ventilating duct 7 between two panels dustproof sheet 9.
As shown in Figure 2 and Figure 3, the nearer sloping platform 10 in the one end of chamfer distance ventilating duct 7 and the ventilating duct nearer apart from it
A cooling fan 14 is provided between 7 one end, a startup electricity with cooling fan 14 is additionally provided with the internal side wall of housing 1
The connected temperature sensor 15 in road, startup radiating can be then triggered when temperature sensor 15 detects that the internal temperature of housing 1 is too high
Blower fan 14 comes into operation.Cooling fan 14 can disturb air when opening running so that produce negative pressure in ventilating duct 7, and by distance
The nearer dustproof sheet 9 of cooling fan 14 to the position of cooling fan 14 attract, make dustproof sheet 9 together around each with ventilating duct 7
Articulated position rotate and between ventilating duct 7 produce a gap., can will be extraneous empty simultaneously as the effect of cooling fan 14
Gas can be by the gap suction ventilation road 7.And because the air velocity in the effect ventilating duct 7 of cooling fan 14 can become
It hurry up so that air pressure in ventilating duct 7 is less than the air pressure of environment in housing 1, and allows temperature is higher in housing 1 air by changing
In the flow ventilation road 7 of stomata 13.Because the air in housing 1 enters in ventilating duct 7, the air pressure in housing 1 diminishes therefore extraneous
The air of normal temperature can be entered inside housing 1 by vent window 4, so as to complete the hot-air in housing 1 and extraneous normal temperature air
Exchange, make the ventilation and heat of housing 1.When the temperature inside temperature sensor 15 detects housing 1 recover to it is normal when, then touch again
Diverging air-heater 14 decommissions to save energy resource consumption.
As shown in Fig. 2 fly net 16 is further fixed at the both ends of ventilating duct 7, to prevent insect opening from the both ends of ventilating duct 7
Mouth climbs into ventilating duct 7, or cooling fan 14 therein can be made by insect suction ventilation road 7 during the running of cooling fan 14
Into influence.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, it is all in this practicality
Within new design concept, any modification, equivalent substitution and improvements made etc., protection of the present utility model should be included in
Within the scope of.
