Problems solved by technology
The existing ones require multiple devices, so when testing the same item, they switch multiple times, and the fixtures are repeatedly searched, transported, disassembled, and the detection efficiency is not high; moreover, the area occupied by multiple devices increases, and the detection function blocks and decoration increase
In addition, the operation of the equipment is more complicated, and the requirements for personnel training are high, and some parameters need to be manually adjusted by turning various switch knobs first.

Embodiment Construction
[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] The product under test in this embodiment is the air outlet assembly of an automobile. In other embodiments, the product under test can also be any other product under test that requires airflow to be detected, such as a computer exhaust fan, an air outlet of an air conditioner, or the like. The cross section in this embodiment refers to the cross section parallel to the cross section perpendicular to the flow direction of the airflow.
[0030] Please refer to Figure 1 to Figure 13 . An airflow detection device provided by the present invention is used to detect a product to be tested. The airflow detection device includes: a first air intake channel 1, a fixture...

The invention provides an air flow detection device for detecting a product to be tested. The air flow detection device includes: a first air intake channel, a fixture installation position, a detection mechanism and a first mixing chamber, and the first air intake channel is provided with a first regulating valve It is used to adjust the flow rate of the airflow in the first air intake channel; the fixture installation position is used to install the product under test; the detection mechanism includes a first flow meter and a first air pressure sensor, and the first flow meter is arranged on the first air intake channel for Detecting the flow rate of the first air intake passage, the first air pressure sensor is arranged near the fixture installation position; and one end of the first mixing chamber communicates with one end of the first intake passage, and the fixture installation position is located at the other end of the first mixing chamber one end.
Description
technical field [0001] The invention relates to the technical field of detection devices, in particular to an airflow detection device. Background technique [0002] Existing devices for detecting air outlets need to perform five tests on multiple devices, including air outlet leakage test, pressure drop test, holding force adjustment, wind direction test, and howling test. The existing one requires multiple devices, so when testing the same item, it is switched multiple times, and the fixture is repeatedly searched, transported, disassembled, and the detection efficiency is not high; moreover, the area occupied by multiple devices increases, and the detection function block and Decoration increases. In addition, the operation of the equipment is more complicated, and the requirements for personnel training are high, and some parameters need to be manually adjusted by turning various switch knobs first. Contents of the invention [0003] The purpose of the present invent...
