[0017] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] See also Figure 1 , Figure 2 and Figure 3The utility model provides an environmental dust detection device, which includes a wind speed sensor 1 and a data analysis component connected thereto; the data analysis component includes a data display screen 00 (which has a PM2.5 sensor therein), an air port 01 connected to the PM2.5 sensor, etc. The data sensed by the wind speed sensor 1 is transmitted to the data analysis component for analysis and display. Since the specific structure of the data analysis component has no direct relationship with the innovative point of the present application, it is only briefly described.

[0019] The wind speed sensor 1 includes a support shaft 2 connected to a data analysis component, a sleeve 3 rotatably mounted on the support shaft and cooperating therewith to sense rotational speed, and a windward bowl 4 arranged around the outer periphery of the sleeve 3 and capable of swinging up and down; components for sensing rotational speed are arranged in the support shaft 2 and the sleeve 3, and the components are of an existing structure, and the size of the wind force is further obtained by sensing the rotational speed data of the sleeve 3. Common components for sensing rotational speed include current type, voltage type, Hall type, etc.

[0020] A first contact 21 is provided at a predetermined position of the support shaft 2; a second contact 41 is provided on the windward bowl 4 to contact the first contact 21 and generate a signal. The rising airflow drives the windward bowl 4 to swing upward and then drives the second contact 41 to contact the first contact 21; when the signal is generated, it indicates that there is an rising airflow at the measuring point. Specifically in this example, the windward bowl 4 is fixedly connected to the sleeve 3 through the connecting rod 5; and the second contact 41 is provided on the connecting rod 5 or the windward bowl 4 (as shown in the figure in this embodiment, the second contact 41 is provided on the connecting rod 5). The connecting rod 5 is installed on the sleeve 3 in a hinged manner (the wind drives the connecting rod 5 to swing upward and resets downward under the state of dead weight). It should be noted that the sleeve 3 is provided with a positioning block that keeps the connecting rod 5 perpendicular to the sleeve 3 under normal conditions (windless state). By vertically setting, the distance between the windward bowl 4 and the sleeve 3 is increased to optimize the perception of wind force by the windward bowl 4.

[0021] The transmission of the above-mentioned signal is realized by the following structure: an electrical connection component is arranged between the support shaft 2 and the sleeve body 3, which includes a first connection ring 6 arranged on the support shaft 2 and a second connection ring 7 arranged on the sleeve body 3 and always in contact with the first connection ring 6; wherein the second contact 41 and the first contact 21 are both electrically connected to the second connection ring 7; the electrical connection can be realized by a wire, a copper sheet, etc. The first connection ring 6 is connected to the data analysis component. By the cooperation between the first connection ring 6 and the second connection ring 7, the sleeve body 3 can be in a rotating state, and the signal transmission can also be realized.

[0022] In the normal state (connecting rod 5 does not swing), the circuit is not turned on because the second contact 41 is not in contact with the first contact 21. When the rising airflow drives the windward bowl 4 and the connecting rod 5 to swing upward, the second contact 41 is in contact with the first contact 21. At this time, the circuit is turned on, and the signal sent by the data analysis component forms a loop, which indicates that there is rising airflow at the measuring point.

[0023] See also Figure 4 Preferably, in order to make the windward bowl 4 better sense the rising airflow, the windward bowl 4 includes a support ring 42 fixed to the connecting rod 5 and a windward bag 43 fixed to the support ring 42. The windward bag 43 is a soft structure, which can be deformed appropriately according to the change of wind direction. For example, when the rising airflow blows toward the windward bag 43, the bag body thereof will be deflected upward.

[0024] In summary, the utility model provides an environmental dust detection device including a wind speed sensor and a data analysis component connected thereto; the data analysis component includes a data display screen, etc., and the data sensed by the wind speed sensor is transmitted to the data analysis component. The wind speed sensor includes a support shaft connected to the data analysis component, a sleeve that is rotatably sleeved on the support shaft and cooperates with the support shaft to realize rotational speed sensing, and a windward bowl that is arranged around the outer periphery of the sleeve and can swing up and down; components for sensing the rotational speed are arranged in the support shaft and the sleeve, and the size of the wind force is further obtained by sensing the rotational speed data of the sleeve. Common components for sensing the rotational speed include current type, voltage type, Hall type, etc. The utility model sets the windward bowl as an active structure, which can be driven by the rising airflow to generate movement, and then cooperate with the contact of the contacts to realize signal transmission, forming a detection circuit.
