Abstract
The utility model relates to a sensor of a heat radiation fan. The utility model is characterized in that an air outlet of a heat radiation fan is provided with an inducting element 2 which can change deformation quantity along with the swing motion of entry wind rate, and when the swing motion is lower than a set normal value, the inducting element 2 drives an alarm circuit unit to work by a circuit of the inducting element 2. The utility model has the advantage that the utility model can remind in time a user of conducting treatment when the detected entry wind rate of the heat radiation fan is insufficient.
Description
The utility model relates to a kind of sensor device of radiator fan, refers to a kind of sensing apparatus that the deficiency in draught what sets numerical value of going into that can detect this radiator fan especially.
At present, the radiator fan of host computer, general system is equiped with filter screen thereon, and this filter screen can be piled up dust and dirt in radiator fan work a period of time, causes the air quantity of suction to reduce, and causes its radiating effect bad.Therefore need a kind of sensing apparatus that the deficiency in draught what sets numerical value of going into that detects radiator fan of design.
The purpose of this utility model is to provide a kind of sensor device of radiator fan, and the deficiency in draught what of going into that this device can detect this radiator fan sets numerical value, reminds the user to be for further processing.
The purpose of this utility model is realized by following technical design scheme: a kind of sensor device of radiator fan, its main points are, can change the sensing element of its deflection with the swing of going into air quantity in the air-out oral area installing one of radiator fan, when its swing is lower than the normal value of setting, then can drive the warning circuit cell operation according to its circuit.
Compared with the prior art the utility model has the deficiency in draught what of going into that can detect radiator fan and sets numerical value, the advantage of in time reminding the user to handle.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a stereographic map of the present utility model
Fig. 2 is a side view of the present utility model
Fig. 3 is the synoptic diagram of pressure sensing element
Fig. 4 is the enforcement illustration that pressure sensing element what radiator fan runs well
Fig. 5 is that of pressure sensing element what radiator fan work running implements illustration
Fig. 6 is another enforcement illustration of pressure sensing element what radiator fan work running
To shown in Figure 4, the sensor device of radiator fan of the present utility model comprises member units such as a radiator fan 1 and a pressure sensing element 2 referring to Fig. 1; Wherein, this radiator fan is a tubeaxial fan, it can be used in what host computer or the air conditioner, be equiped with a filter screen 11 on this radiator fan, in order to pile up dust and dirt, (this circuit adopts prior art then to be provided with a circuit substrate in this radiator fan, not shown in the figures), circuit substrate is provided with the one drive circuit unit, and the sound sound of caution can be sent in the caution sound acoustic-electric road of this drive circuit unit when the abatement of wind that radiator fan blows out (low its established standards data value of what).
When closing (OFF) state when power supply remains on, this radiator fan does not rotate, and feeling of stress side element can not be out of shape; Otherwise power supply is when (ON) state of unlatching, and this radiator fan is worked, and pressure sensing element can be with its rotational deformation.
By this, when this radiator fan in normal operation, it can obtain a setting voltage value (this numerical value can set up its sensitivity on their own, is in the present embodiment to be set in 1/2 place, as the 4th figure, also can be set in 1/3 or 1/4 place).
When this radiator fan in normal operation, and make the magnitude of voltage of pressure sensing element output higher (meaning is promptly gone into air quantity and surpassed the normal value of setting), as the 5th figure, then the caution sound acoustic-electric Lu Buhui of this radiator fan drive circuit unit sends caution sound sound.When this radiator fan too much reduces its operating condition because of filter screen 11 dirt are long-pending, the magnitude of voltage of this pressure sensing element output is on the low side, and (meaning promptly, go into the normal value that the low what of air quantity is set), as the 6th figure, cause the caution sound acoustic-electric road of the drive circuit unit of radiator fan can send caution sound sound, remind the user.
In addition, according to the needs in the design and use, described sensing element can be a capacitive element; Described sensing element also can be a ultrasonic element.Described warning circuit unit can be a sound sound warning circuit; Described warning circuit unit also can be a light warning circuit.
