Description

Technical Field

[0001] The utility model relates to the field of differential pressure sensors, in particular to an integrated differential pressure sensor. Background Art

[0002] A differential pressure sensor is a sensor used to measure the difference between two pressures. It is usually used to measure the pressure difference between the front and rear ends of a device or component, and is widely used in ventilation systems. It mainly connects the high-pressure air inlet and the low-pressure air inlet to the upwind and downwind outlet of the measured pipeline respectively. The wind in the measured pipeline first enters the high-pressure air inlet through the connecting pipe, then enters the low-pressure air inlet through the connecting pipe, and then enters the differential pressure sensor to detect the air pressure difference.

[0003] According to a Chinese patent with the publication number "CN214538339U", a differential pressure sensor is disclosed, which relates to the field of sensor technology, including a shell, the top of the shell is hinged with an upper cover through a hinge, the bottom of the inner wall of the shell is fixedly connected with a vertical plate, the front and back sides of the vertical plate are fixedly connected with a guide shaft, the outer sleeve of the guide shaft is provided with a slider, the guide shaft sleeve is provided with a shock-absorbing spring, and the slider is connected to a shock-absorbing connecting rod. Due to the cooperation of the upper connecting block, the shock-absorbing connecting rod and the slider, the impact force in the vertical direction is converted into the impact force on the shock-absorbing spring in the horizontal direction, so that most of the rebound impact force generated by the shock-absorbing spring when resetting is parallel to the component placement plate, thereby reducing the effect of the rebound impact force of the shock-absorbing spring on the differential pressure sensor component when resetting, thereby solving the problem that the spring is directly used to shock the differential pressure sensor component in the comparative example, and the rebound impact force of the spring itself when resetting will also damage the differential pressure sensor component;

[0004] It can be seen from the above structure that the above device converts the vertical impact force into the horizontal impact force on the shock-absorbing spring due to the cooperation of the upper connecting block, the shock-absorbing connecting rod and the slider. As a result, most of the rebound impact force generated by the shock-absorbing spring when resetting is parallel to the component placement plate, thereby reducing the effect of the rebound impact force of the shock-absorbing spring on the pressure difference sensor component when resetting, thereby solving the problem in the comparative example that the spring is directly used to cushion the pressure difference sensor component, and the rebound impact force of the spring itself when resetting will also damage the pressure difference sensor component. When the existing pressure difference sensor detects the pressure difference at the front and rear ends of the pipeline, the ventilation connecting pipe may shake violently under the action of wind pressure, which may easily cause the connection between the connecting pipe and the measured pipeline and the pressure sensor to loosen, resulting in partial gas leakage, affecting the accuracy of the measured pressure difference value, and the existing sensor connecting line is likely to cause the connecting rope to be entangled when it is too long.

[0005] To this end, we propose an integrated differential pressure sensor to solve the above problems. Utility Model Content
