Description

Technical Field

[0001] The utility model relates to the field of air quality monitoring equipment, in particular to an air quality monitoring equipment with an early warning function. Background Art

[0002] With the increasing severity of environmental pollution, air quality monitoring equipment has become an important part of our lives. However, traditional air quality monitoring equipment usually only has basic monitoring functions and cannot provide users with timely and accurate early warning information. This makes it difficult for users to take timely countermeasures when facing deteriorating air quality, posing a potential threat to health. In order to solve this problem, there is an air quality monitoring device with an early warning function in the existing equipment. The device can not only monitor the air quality in real time, but also predict the future trend of air quality changes based on the monitoring data, and issue early warning information when necessary to remind users to take corresponding protective measures. However, since its monitoring function relies on electronic alarm generation and transmits signals to the control terminal for observation by the monitor, there is no concrete reminder. Therefore, residents and pedestrians in the area who cannot directly observe the control terminal cannot intuitively understand the air quality monitoring device in the area environment. Utility Model Content

[0003] The utility model provides an air quality monitoring device with an early warning function, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problem is:

[0005] An air quality monitoring device with an early warning function comprises an air quality monitoring body, an air quality sensor, an indicator light, a motor, and a buzzer, wherein the air quality sensor is respectively connected to the indicator light and the motor by signals, the indicator light is installed on the outside of the air quality monitoring body, and the motor is placed inside the air quality monitoring body, and a buzzer is connected to the output shaft of the motor;

[0006] The surface of the indicator light is provided with three indicator lights for displaying the air quality, and the light colors of the three indicator lights are red, yellow and green respectively.

[0007] A preferred technical solution: The buzzer includes a shell, a rotating block, an extension part, and a ball bearing. The output shaft of the motor passes through the shell, and the rotating block is installed on the output shaft of the motor, and the outer side of the rotating block abuts against the inner side of the shell, and the upper surface of the shell is connected to the outside through a connecting port;

[0008] The side of the shell is also connected to an extension part, in which a ball is movably installed, and the extension part is connected to the outside through a chirping port, and the outer diameter of the ball is smaller than the inner diameter of the chirping port.

[0009] A preferred technical solution: the inner diameter of the connecting end between the shell and the extension portion is smaller than the inner diameter of the ball.

[0010] Compared with the background technology, this technical solution has the following advantages:

[0011] When in use, the utility model can control the frequency of sending electrical signals to the motor through the severity of air quality monitoring by the air quality sensor, that is, the worse the air quality, the higher the frequency of the electrical signal received by the motor, thereby causing the motor output shaft to rotate faster. Therefore, it can be understood that when the output shaft of the motor rotates faster, the rotating block connected to the motor output shaft will gradually increase the rotation speed in the shell, compressing the air between the connecting port and the extension part, and allowing the air to be discharged outward along the chirping port during squeezing. The vibration frequency of the air is increased by pressurizing the air, and the air at the chirping port makes a chirping sound, which is easy for people around to identify.

[0016] like Figure 1-2As shown, an air quality monitoring device with an early warning function includes an air quality monitoring body 1, an air quality sensor 2, an indicator light 3, a motor 4, and a buzzer 5. The air quality sensor 2 is respectively connected to the indicator light 3 and the motor 4 by signal. The indicator light 3 is installed on the outside of the air quality monitoring body 1, and the motor 4 is placed in the air quality monitoring body 1, and a buzzer 5 is connected to the output shaft of the motor 4. The surface of the indicator light 3 is respectively provided with three indicator lights for displaying air quality, and the light colors of the three indicator lights are red, yellow, and green, respectively. It can be understood that in the utility model, the air quality sensor 2 is used to monitor harmful gases or air quality in the air, and the threshold standard of the air quality monitored by the air quality sensor 2 can be changed with the operator, and the indicator light 3 can be used to display the relationship between the air quality and the threshold, such as standard, approaching, exceeding, etc., and different meanings can be expressed by corresponding colors of the three indicator lights to words with different meanings, so as to remind people around the air quality monitoring device.

[0017] In order to further improve the warning effect of the air quality monitoring equipment in the utility model on the surrounding personnel, the following improvements are made:

[0018] The buzzer 5 includes a shell 51, a rotating block 52, an extension 53, and a ball 54. The output shaft of the motor 4 passes through the shell 51, and the rotating block 52 is installed on the output shaft of the motor 4, and the outer side surface of the rotating block 52 is against the inner side surface of the shell 51, and the upper surface of the shell 51 is connected to the outside through a connecting port 511; the side of the shell 51 is also connected to an extension 53, and a ball 54 is movably installed in the extension 53, and the extension 53 is connected to the outside through a buzzing port 531. The outer diameter of the ball 54 is smaller than the inner diameter of the buzzing port 531, and the inner diameter of the connecting end of the shell 51 and the extension 53 is smaller than the inner diameter of the ball 54. When in use, the air quality sensor 2 can detect the air quality. The frequency of sending electrical signals to the motor 4 is controlled by the severity of the quality monitoring, that is, the worse the air quality is, the higher the frequency of the electrical signals received by the motor 4, which leads to faster rotation speed of the output shaft of the motor 4. Therefore, it can be understood that when the output shaft of the motor 4 rotates faster, the rotating block 52 connected to the output shaft of the motor 4 will gradually increase the rotation speed in the shell 51, compressing the air between the connecting port 511 and the extension portion 53, and when squeezed, the air is discharged outward along the chirping port 531, and the vibration frequency of the air is increased by pressurizing the air, so that the air at the chirping port 531 makes a chirping sound, which is convenient for people around to identify, and when the airflow flows rapidly, the ball 54 can quickly hit the inner side of the extension portion 53 to increase the chirping sound.

[0019] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
