Detailed Implementation
[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0020] In recent years, pressure detectors have been widely used in various industrial fields. However, traditional pressure detectors typically mount the sensor element externally for ease of maintenance and replacement. While this design offers convenience in maintenance, it also leads to increased equipment size, occupies more space, and makes the sensor element more susceptible to damage in the event of impacts, increasing maintenance costs. This design is particularly inconvenient in certain space-constrained situations.
[0021] Reference Figures 1 to 3 This utility model provides a pressure detector that significantly reduces the device's size and lowers the risk of sensor element damage by placing the sensor 240 inside the housing. The pressure detector includes a housing and a detection assembly. The housing has a positioning tube 140 that passes through it, with its first end 141 inside the housing and its second end 142 extending outside. The detection assembly, located inside the housing, includes a control module and the sensor 240. The sensor 240 is connected to the first end 141 of the positioning tube 140, and external pressure is transmitted to the sensor 240 through the positioning tube 140. The sensor 240 is electrically connected to the control module.
[0022] By internalizing the sensor 240, the size and space occupied are reduced, while the possibility of the sensor 240 being damaged by external factors is reduced, the reliability of the device is improved, and the frequency and cost of maintenance are also reduced.
[0023] The housing provides protection and support, while the positioning tube 140 connects the sensor 240 to an external pressure source. The sensor 240 detects pressure changes and transmits the signal to the control module for processing. By placing the sensor 240 inside the housing, its exposure to the external environment is avoided, thus reducing its size and the risk of damage from impacts.
[0024] Understandably, referring to Figure 2 and Figure 3 The first end 141 of the positioning tube 140 is provided with a positioning element 143. The positioning element 143 has a positioning hole that communicates with the positioning tube 140. The sensor 240 is threadedly connected to the positioning hole. The positioning element 143 protects the sensor 240. Through the threaded connection between the sensor 240 and the positioning element 143, the sensor 240 can be securely installed inside the housing, preventing it from shaking and bumping inside the housing. Furthermore, the threaded connection improves the fit between the detection end of the sensor 240 and the end face of the first end 141, enhances the airtightness between the sensor 240 and the positioning tube 140, improves detection accuracy, and facilitates installation and disassembly.
[0025] Understandably, referring to Figure 2 and Figure 3The control module includes a control board 210 and a power supply 231. The sensor 240 is electrically connected to the control board 210, and the power supply 231 is also electrically connected to the control board 210. Through its electrical connections with the sensor 240 and the power supply 231, the control board 210 processes the signals from the sensor 240 and supplies power to the power supply 231, ensuring stable operation of the sensor 240 and transmitting the detected pressure information to the control board 210 for processing.
[0026] Understandably, referring to Figure 2 and Figure 3 The housing is equipped with a protective compartment 232, and the protective compartment 232 has a positioning groove 233, within which the power supply 231 is housed. By placing the power supply 231 within the positioning groove 233, the power supply 231 is positioned, ensuring its stable fixation within the housing and preventing movement or loosening during equipment use, thereby improving the stability and safety of the equipment. It also facilitates the disassembly and replacement of the power supply 231, reducing the difficulty of disassembly and improving the convenience of maintenance.
[0027] Understandably, referring to Figure 3 The control module also includes a transformer board 220, which is electrically connected to the power supply 231 and the control board 210. The transformer board 220 is provided with a charging port 221, and the housing has a clearance hole 111 that mates with the charging port 221. The clearance hole 111 allows the power supply 231 wire to pass through and connect to the charging port 221. The function of the transformer board 220 is to regulate the voltage of the power supply 231 to a voltage suitable for the control board 210 and other components. The charging port 221 on the transformer board 220 can charge the internal power supply 231. The design of the clearance hole 111 ensures that the housing does not need to be disassembled or its structural integrity affected during charging. The connection between the clearance hole 111 and the charging port 221 can be implemented in various ways, such as by plugging or magnetic connection.
[0028] Understandably, referring to Figure 3 The transformer plate 220 is attached to the control board 210. The attached design of the transformer plate 220 and the control board 210 ensures a tight connection between them, improves the connection stability and reliability between the transformer plate 220 and the control board 210, avoids failure problems caused by poor connection, and at the same time reduces volume and improves the utilization rate of the internal space of the housing.
[0029] Understandably, referring to Figure 1 and Figure 2The housing includes a display 130, which is electrically connected to the control board 210. The display 130 shows the detected pressure for easy and intuitive viewing. The display 130 can be of various types, such as an LCD screen or an LED screen, and the specific choice can be adjusted according to actual needs and cost. The electrical connection between the display 130 and the control board 210 can be via a wire or a wireless module, depending on the specific application scenario.
[0030] Understandably, referring to Figure 3 The housing includes a main body 110 and a cover 120. One side of the main body 110 has an opening, and the cover 120 is detachably fitted over the opening. The detachable design of the cover 120 facilitates inspection, component replacement, and maintenance, reducing maintenance costs. Furthermore, the shape and size of the cover 120 can be adjusted according to actual needs to ensure a tight fit with the opening of the main body 110, effectively preventing external dust or moisture from entering the housing.
[0031] Understandably, referring to Figure 2 and Figure 3 One side of the cover 120 protrudes to form a plug-in portion 121, which matches the opening and engages with it. The plug-in portion 121 engages with the opening to quickly position the cover 120, improving the assembly efficiency of the cover 120 and the main body 110, while reducing the risk of shaking after assembly and improving stability.
[0032] Understandably, the open sidewall protrudes to form a first protrusion 112, and the insertion part 121 has a groove 123 on the side facing the first protrusion 112. The groove 123 protrudes to form a second protrusion 122 on the side facing the first protrusion 112, and the second protrusion 122 can engage the first protrusion 112 in the groove 123.
[0033] Rotate the cover 120 so that the first protrusion 112 slides in the groove 123. After the second protrusion 122 abuts against the first protrusion 112, continue to rotate so that the first protrusion 112 passes over the second protrusion 122. The first protrusion 112 is located between the second protrusion 122 and the end side wall of the groove 123, and the first protrusion 112 is engaged in the groove 123 to ensure a firm connection between the cover 120 and the body 110, prevent the cover 120 from loosening or falling off, thereby avoiding exposure of the internal components and protecting the internal components.
