As shown in FIGS. 1 to 5, an air box 100 according to an embodiment of the present invention includes a housing 1, a plurality of support members 2, and a main control board 3. Therein, a plurality of support members 2 are arranged in the housing 1 at a distance from each other, each support member 2 comprising a hollow support seat 21. The main control board 3 is supported on the support base 21 of the plurality of support members 2.

For example, as shown in FIG. 1 and FIG. 3 to FIG. 5, the housing 1 may include a first housing 11 and a second housing 12, respectively, and the first housing 11 and the second housing 12 are substantially half-ball housings 1, respectively. The first housing 11 and the second housing 12 cooperate with each other to form a substantially spherical structure. Specifically, the top of the first housing 11 is open and the bottom of the second housing 12 is open. Open, and the second housing 12 is disposed at the top of the first housing 11, the first housing 11 and the second housing 12 together define a main control panel 3, a plurality of supports 2 and sensors (including The accommodation space of each component such as the PM2.5 sensor 32, the temperature sensor, and the humidity sensor mentioned in the text, at this time, the accommodation space functions to accommodate various components such as the main control board 3 and the sensor.

It can be understood that the specific shape, the specific arrangement, and the like of the first housing 11 and the second housing 12 can be specifically set according to actual requirements. For example, the structure formed by the first housing 11 and the second housing 12 can also be configured. Is a square shape, a rectangular parallelepiped shape, a cylindrical shape, an elliptical cylindrical shape, a long cylindrical shape or a prismatic shape, etc. (not shown); and the first housing 11 and the second housing 12 are not shown in FIG. In addition to the upper and lower arrangement shown in Fig. 5, left and right or front and rear arrangements (not shown) may be employed to better meet the actual requirements.

Referring to FIG. 1 and in conjunction with FIG. 2, a plurality of support members 2 are disposed in the first housing 11 and spaced along the circumferential direction of the first housing 11, and at this time, the plurality of support members 2 are not in contact with each other. The support base 21 of each support member 2 has a hollow structure, and the main control board 3 is adapted to be supported on a plurality of support bases 21, and at this time, the main control board 3 is located on the upper side of the plurality of support bases 21. Thus, by providing the support base 21 for supporting the main control board 3 as a hollow structure, when the air box 100 is dropped or abnormally collided, the support base 21 can be deformed to serve as a cushioning function, thereby reducing The force transmitted to the main control board 3 serves the purpose of protecting the main control board 3 and components inside the casing 1 (for example, sensors provided on the main control board 3, etc.).

According to the air box 100 of the embodiment of the present invention, by disposing the main control board 3 on the hollow support base 21, when the air box 100 is dropped or collided, the hollow support base 21 can serve as a buffering function for the main control board. 3 protection, thereby greatly reducing the damage to the main control board 3, extending the service life of the main control board 3, and ensuring the normal use of the air box 100.

For example, in the example of FIG. 2, two support legs 212 are respectively connected at the bottom ends of the support plate 211, and the upper ends of the two support legs 212 are connected to the support plate 211, and the support base 21 is realized by the two support legs 212 and the housing. The connection of 1 is that the support base 21 is generally a gate-shaped structure, and the main control board 3 is adapted to be supported on the upper surface of the support plate 211. Thus, the support plate 211 of the support base 21 and the two support legs 212 can be regarded as defining an opening penetrating in the width direction of the support leg 212, and the upper end of the support base 21 when the air box 100 collides or falls. The main control board 3 can be buffered and reduced. The force transmitted to the components in the casing 1 such as the main control board 3 due to collision or drop is reduced, thereby functioning as a component such as the main control board 3 in the protective casing 1.

Further, referring to FIG. 1 and in conjunction with FIG. 4 and FIG. 5, the main control board 3 is provided with a sensor, and the sensor may include PM2.5 (fine particles, also referred to as fine particles and fine particles, and fine particles refer to aerodynamic equivalents in ambient air. At least one of a particle, a particle having a diameter of 2.5 μm or less, a sensor, a temperature sensor, and a humidity sensor. Preferably, the sensor includes both a PM2.5 sensor 32, a temperature sensor, and a humidity sensor to detect the concentration of dust (i.e., the magnitude of PM2.5), temperature, and humidity in the air flowing through the sensor, respectively.

When the PM2.5 sensor 32, the temperature sensor, and the humidity sensor are applied to the air box 100, the temperature sensor and the humidity sensor may be located upstream of the PM2.5 sensor 32, at which time the air first passes through the temperature sensor and the humidity sensor to detect the air. The temperature and humidity are then passed through the PM2.5 sensor 32 to detect the concentration of dust in the air. Thus, this arrangement improves the accuracy of detecting the temperature and humidity of the air and the concentration of dust in the air.

Among them, the temperature sensor and the humidity sensor can be integrated into one, that is, the temperature and humidity sensor, when the air flows through the temperature and humidity sensor, the temperature and humidity sensor can detect the temperature and humidity of the air.

Therefore, when the sensor is mounted on the main control board 3, the support base 21 can simultaneously buffer the sensor, reduce the force transmitted to the sensor, thereby simultaneously achieving the purpose of protecting the sensor, and prolonging the service life of the sensor, and ensuring The normal use of the air box 100.
