Description

Wind speed detecting device

The invention relates to a wind speed detecting device.

At present, most of the wind speed measuring devices on the market are electronic, such as a hot wire anemometer, which is measured by a sensor, so that the wind speed at any time can be known. However, in actual production life, people often care about whether the measured wind speed exceeds a certain critical value rather than the wind speed. For example, in some computer systems, if the fan speed (the fan speed directly determines the wind speed) exceeds a certain threshold, the computer system will automatically stop running. In such cases, if an electronic wind speed measuring device is used, the cost is too high.

In view of the above, it is necessary to provide a low-cost wind speed detecting device.

A wind speed detecting device for detecting a wind speed, comprising a wind speed detecting switch and a connector electrically connected to the wind speed detecting switch, the wind speed detecting switch comprising a stylus and a spring piece contacting the stylus when the measured wind When the wind speed does not blow the shrapnel away from the stylus, the stylus contacts the shrapnel, and the wind speed detecting switch is closed. When the wind speed is sufficiently large to blow the shrapnel away from the stylus, the wind speed detecting switch is turned off. The connector is for connecting an indicator indicating an open/close state of the wind speed detecting switch.

The wind speed detecting device of the present invention uses a wind speed detecting switch instead of an expensive sensor, which greatly reduces the cost.

Referring to FIGS. 1 and 2, a preferred embodiment of the wind speed detecting device 8 of the present invention includes a body 10 and a cover 90.

The body 10 includes a base 20, a circuit board 40 mounted on the base 20, a screw 60, and a spring 80.

The base 20 includes a chassis 21, a taller rear wall 23, a lower front wall 25, and two lower side walls 27. The rear wall 23, the front wall 25, and the side walls 27 are all vertically extended upward from the chassis 21. The rear wall 23 is disposed opposite to the front wall 25. The two side walls 27 are oppositely disposed and connected between the rear wall 23 and the corresponding end of the front wall 25, respectively. A plurality of air outlet holes 231 and a screw hole 233 are defined in the rear wall 23. A hook 29 is respectively protruded from the front wall 25 and the side wall 27.

The circuit board 40 is housed in the susceptor 20. The circuit board 40 is provided with an L-shaped stylus 41, a spring 43 and a connector 47. The bottom end of the elastic piece 43 is fixed on the circuit board 40, and the remaining part of the elastic piece 43 is displaced relative to the bottom end of the elastic piece 43. The elastic piece 43 includes a flat piece 431 and two side pieces 433. The flat piece 431 is used to be in contact with the stylus 41. The side panels 433 are respectively extended from the left and right ends of the flat sheet 431 toward the side where the stylus 41 is located, and are at an obtuse angle with the flat sheet 431. The stylus 41 and the elastic piece 43 constitute the wind speed detecting switch 45 of the present invention. The connector 47 is provided with an interface (not shown) for connecting an indicator 49 (see Fig. 4). The circuit board 40 is provided with or can be connected to a power source or a high level.

Referring also to FIG. 3, the screw 60 includes a thicker threaded portion 61 and a thinner rod 63 extending from one end of the threaded portion 61. The screw 60 is attached to the screw hole 233 of the base 20 through the screw portion 61 thereof. The rod 63 of the screw 60 extends into the base 20. The spring 80 is sleeved on the rod 63, and the two ends thereof respectively abut against the threaded portion 61 and the flat piece 431 of the elastic piece 43. Screw 60 and spring 80 constitute a threshold setter 70 of the present invention.

The cover 90 includes a rectangular top plate 91, a front plate 95, and side plates 97. The front plate 95 extends downward from the front end of the top plate 91. The side plates 97 are respectively extended from the left and right ends of the top plate 91. The front plate 95 and the side plate 97 respectively define a snap hole 99 near the bottom end thereof. The front plate 95 also has a plurality of air inlet holes 951. The cover 90 is attached to the base 20 by a snap fit of its snap hole 99 with a corresponding hook 29 of the base 20 such that the front panel 95 of the cover 90 opposes the rear wall 23 of the base 20. A corresponding side plate 97 of the cover 90 is also provided with an opening for exposing the interface on the connector 47. The cover 90 is used to protect the circuit board 40 and facilitate the maintenance of the circuit board 40. Additionally, in other embodiments, the snap holes 99 and the hooks 29 are interchangeable.

Referring to FIGS. 3 and 4, when detecting the wind speed, the indicator 49 is electrically connected to the wind speed detecting switch 45 through the connector 47 to indicate the opening and closing operation state of the wind speed detecting switch 45. The spring 80 of the threshold setter 70 provides an elastic force to the elastic piece 43 so that the elastic piece 43 always tends to maintain contact with the stylus 41. The screw 60 is rotated to adjust the spring force of the spring 80 for setting the threshold value of the wind speed. The measured wind enters the wind speed detecting device 8 from the air inlet 951. When the wind speed is greater than the wind speed threshold, that is, when the force of the wind on the elastic piece 43 is greater than the elastic force of the spring 80, the elastic piece 43 is blown off the stylus 41 to cause the wind speed detecting switch 45 to be turned off, and the indicator 49 indicates to the user. The wind speed detecting switch 45 is turned off. When the wind speed is less than the wind speed threshold, the wind speed detecting switch 45 remains closed while the indicator 49 indicates to the user the operating state in which the wind speed detecting switch 45 is closed.

Referring to FIG. 5, in the present embodiment, the wind speed detecting switch 45 is connected between the positive and negative poles of the power source or between the high and low levels. The indicator 49 is a light-emitting diode, and its two poles are respectively connected to the two ends of the wind speed detecting switch 45 through the connector 47. When the wind speed detecting switch 45 is closed, the voltages across the light emitting diodes are equal without emitting light to instruct the user to indicate that the wind speed detecting switch 45 is closed. When the wind speed detecting switch 45 is turned off, the light emitting diode emits light to instruct the user to instruct the wind speed detecting switch 45 to be turned off. In the present embodiment, the connector 47 actually only acts as a wire, so the connector 47 can be omitted in other embodiments. Additionally, in other embodiments, the indicator 49 can also be a multimeter. When the multimeter is set to the resistance file, when the multimeter display resistance is zero, it means that the wind speed detection switch 45 is closed; when the multimeter shows that the resistance is infinite, it means that the wind speed detection switch 45 is off.

In other embodiments, the indicator 49, such as the light emitting diode, can be directly mounted to the base 20 or the cover 90, or directly disposed on the circuit board 40. At the same time, the connector 47 can be omitted.

In other embodiments, if the wind speed threshold is not required to be adjustable, the threshold setter 70 can be omitted, and the wind speed threshold value fixed by the elastic force of the elastic piece 43 itself can be used.

It should be noted that the two side pieces 433 of the elastic piece 43 facilitate the receiving of the wind force by the elastic piece 43, but in other embodiments, the side piece 433 can be omitted. In addition, the bottom end of the elastic piece 43 is also pivotally coupled to the circuit board 40.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
