Title:
SENSOR DEVICE AND VALVE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2022/142994
Kind Code:
A1
Abstract:
A sensor device, comprising: a housing (1) and a sensing assembly (2), the sensing assembly (2) comprising a circuit substrate (21), a sensing element (22), and a sleeve (23), and further comprising an inner cavity (200) and a channel (231). The inner cavity (200) and the channel (231) are located on different sides of the thickness direction of the circuit substrate, respectively. The sleeve (23) has a cylinder wall (232). The tail end of the cylinder wall (232) in the axial direction of the channel is sealably connected to the circuit substrate (21). The cylinder wall (232) of the sleeve (23) is located on the periphery of the channel (231). The housing (1) is provided with a matching part (11). The matching part (11) is provided with an accommodation part (111). The sleeve (23) is at least partially accommodated in the accommodation part (111). The matching part (11) comprises a first peripheral wall part (112) forming the accommodation part (111). The first peripheral wall part (112) is sealably connected to the outer peripheral side of the cylinder wall (232) of the sleeve (23). The inner cavity (200) is not communicated with the channel (231). The sealing performance between the inner cavity (200) of the sensor device and a flow channel is good. Also provided is a valve assembly (300) having the sensor device.
