It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] The embodiment of the present invention provides a pluggable temperature sensor 21 device for a water sample conductivity cell, such as Figure 1-7 As shown, it includes: a terminal 10, a sensor assembly 20 and a reset assembly 30, the terminal 10 is used to be installed on the water sample conductivity cell, the sensor assembly 20 is detachably connected to the terminal 10, and the reset assembly 30 is elastic; The terminal 10 is provided with a first flow channel 11, a cavity 12 and a second flow channel 13 which are connected in sequence. The sensor assembly 20 and the reset assembly 30 are both installed in the cavity 12. The sensor assembly 20 includes a temperature sensor 21. One end of the temperature sensor 21 is located between the first flow channel 11 and the second flow channel 13. One end of the sensor assembly 20 is crimped with one end of the reset assembly 30. The reset assembly 30 is fixedly installed in the cavity 12 relative to one end of the temperature sensor 21. In this embodiment, the sensor assembly 20 is detachably connected to the terminal 10, which is convenient for installation and maintenance, and improves the convenience and operability of the device. Among them, after the water sample to be detected flows out of the first flow channel 11, it passes through the gap between the sensor assembly 20 and the reset assembly 30 and flows into the second flow channel 13; the temperature sensor 21 is used to detect the temperature of the water sample flowing out of the first flow channel 11; the reset assembly 30 has a third flow channel 333, and the third flow channel 333 is used to connect the first flow channel 11 and the second flow channel 13 after the sensor assembly 20 is disassembled. In this embodiment, since the reset assembly 30 is elastic, the reset assembly 30 can be automatically reset after the sensor assembly 20 is disassembled, and the water sample flow path is not interrupted, ensuring the continuous operation of the device.

[0024] It should be noted that the pluggable temperature sensor 21 device for a water sample conductivity cell provided by the present invention can detect the temperature of the water sample flowing out of the first flow channel 11 through the temperature sensor 21 because the water sample to be detected flows out of the first flow channel 11 and passes through the gap between the sensor assembly 20 and the reset assembly 30 and flows into the second flow channel 13; since the sensor assembly 20 is detachably connected to the terminal 10, the sensor assembly 20 can be disassembled and replaced separately; the third flow channel 333 of the reset assembly 30 connects the first flow channel 11 and the second flow channel 13 after the sensor assembly 20 is disassembled, ensuring that the water sample flow path is not interrupted. Therefore, the pluggable temperature sensor 21 device for a water sample conductivity cell provided by the present invention solves the technical problem that the sensor cannot be disassembled in the prior art.

[0025] like Figure 3As shown, the sensor assembly 20 further includes a sensor housing 22, one end of the sensor housing 22 is crimped to one end of the reset assembly 30, the temperature sensor 21 passes through the sensor housing 22, and the temperature sensor 21 and the sensor housing 22 are bonded and fixed by a first adhesive layer 23. In the specific implementation process, a third mounting groove 224 for accommodating the first adhesive layer 23 is provided in the sensor housing 22; the first adhesive layer 23 is epoxy resin adhesive or other adhesive.

[0026] like Figure 3 and Figure 7 As shown, a rotating block 221 is provided on the outer wall of the sensor housing 22, and a slot 14 is provided in the cavity 12 to rotate and engage with the rotating block 221; in the specific implementation process, the number of the rotating block 221 and the slot 14 is set to two, and the rotating block 221 and the slot 14 correspond to each other one by one; the two rotating blocks 221 are relatively distributed on the outer wall of the sensor housing 22, and the two slots 14 are relatively distributed in the cavity 12; The sensor housing 22 is sleeved with a first sealing ring 40, which abuts against the inner wall of the cavity 12. In the specific implementation process, the outer wall of the sensor housing 22 is provided with a fourth mounting groove 225, and the first sealing ring 40 is sleeved in the fourth mounting groove 225; the first sealing ring 40 is made of silicone or rubber material, and the first sealing ring 40 is set in an O shape; through the sealing effect of the first sealing ring 40, the sensor assembly 20 and the terminal 10 can be effectively sealed.

[0027] It should be noted that when the sensor assembly 20 needs to be installed in the terminal 10, the sensor assembly 20 can be installed in place by inserting the rotating block 221 into the slot 14 and rotating the sensor housing 22 90 degrees clockwise or counterclockwise; illustratively, the rotating block 221 of the sensor housing 22 of the present invention is inserted into the slot 14, and then rotated 90 degrees counterclockwise, and the sensor housing 22 is installed in place; conversely, after the sensor housing 22 is rotated 90 degrees clockwise, the sensor housing 22 can be pulled out of the terminal 10, thereby realizing the rapid disassembly and assembly of the sensor assembly 20.

[0028] like Figure 3 and Figure 7As shown, a crimping platform 222 is provided at one end of the sensor housing 22 located in the cavity 12, and the crimping platform 222 contacts one end of the reset assembly 30; a gap is set between one end of the temperature sensor 21 located in the cavity 12 and the end of the reset assembly 30. In the specific implementation process, the number of crimping platforms 222 is set to two, and the two crimping platforms 222 are relatively arranged at one end of the sensor housing 22, and the sensor housing 22 and the crimping platform 222 are integrally formed; through the arrangement of the crimping platform 222, the crimping platform 222 contacts one end of the reset assembly 30, preventing the reset assembly 30 from directly contacting the temperature sensor 21, and effectively protecting the temperature sensor 21.

[0029] like Figure 3-7 As shown, the outer wall of one end of the sensor housing 22 is provided with a plurality of grooves 223 along its circumference. In the specific implementation process, the plurality of grooves 223 are distributed at equal intervals. The arrangement of the grooves 223 can enhance the friction between the user's hand and the sensor housing 22, making it convenient for the user to rotate the sensor housing 22, which is convenient to use and saves time and effort.

In the specific implementation process, the second sealing ring 50 is sleeved with the sensor housing 22. The second sealing ring 50 is made of silicone or rubber material, and the second sealing ring 50 is arranged in an O shape; through the sealing effect of the second sealing ring 50, the device is effectively sealed.

[0031] It should be noted that when the sensor assembly 20 is in detection operation, the second sealing ring 50 is sleeved with the sensor housing 22; after the sensor assembly 20 is disassembled, the second sealing ring 50 is sleeved with the movable end of the reset assembly 30; thereby ensuring that the device is effectively sealed in two different states.

[0032] like Figure 3-5 As shown, the reset assembly 30 includes a reset mounting platform 31, a reset spring 32 and a reset rod 33 which are arranged in sequence. The reset rod 33 is slidably connected to the reset mounting platform 31. The reset mounting platform 31 is fixedly installed in the cavity 12. One end of the internal cavity of the reset mounting platform 31 is open and the other end is closed. One end of the reset spring 32 abuts against the inner wall of the reset mounting platform 31, and the other end of the reset spring 32 abuts against the reset rod 33. The third flow channel 333 is provided at one end of the reset rod 33 relative to the reset mounting platform 31, and one end of the sensor assembly 20 contacts the reset rod 33. In the specific implementation process, the reset rod 33 is provided in a T-shape.

[0033] It should be noted that when the sensor assembly 20 is installed on the terminal 10 for detection, the crimping platform 222 squeezes the reset rod 33, so that the reset rod 33 squeezes the reset spring 32; when the sensor assembly 20 is disassembled, the crimping platform 222 is separated from the reset rod 33, and the reset rod 33 rebounds under the elastic force of the reset spring 32, and one end of the reset rod 33 passes through the second sealing ring 50, so that the third flow channel 333 is aligned and connected with the first flow channel 11 and the second flow channel 13, ensuring that the water sample circuit is not interrupted and the operation of the water sample conductivity cell is avoided from being interrupted.

The two sliders 332 are respectively relatively to the outer wall of the reset rod 33. The slider 332 and the reset rod 33 are an integrally formed structure. A first mounting surface 122 is provided in the cavity 12, and a first positioning surface 313 of the reset mounting platform 31 adapted to the first mounting surface 122; through the setting of the first positioning surface 313 and the first mounting surface 122, the reset assembly 30 can be quickly positioned and installed in the cavity 12.

[0036] It should be noted that, through the provision of the slider 332 and the slide groove 312 , it is convenient for the reset rod 33 to slide in a positioning manner on the reset mounting platform 31 .

[0037] like Figure 3As shown, the reset mounting platform 31 is bonded and packaged in the cavity 12 by the second adhesive layer 70.

[0038] like Figure 8 and Fig. 9 As shown, a locking assembly 80 is provided on the terminal 10, and the locking assembly 80 is used to lock the sensor assembly 20. It should be noted that the setting of the locking assembly 80 prevents the user or other person from accidentally rotating the sensor assembly 20, thereby affecting the normal operation of the sensor assembly 20.

[0039] like Figure 8 and Fig. 9 As shown, the locking assembly 80 includes a locking platform 81 installed on the terminal 10, the locking platform 81 is penetrated with a locking block 82, a locking spring 83 is installed in the locking platform 81, and a locking groove 226 is provided on the sensor assembly 20; in the specific implementation process, a locking column 811 is provided in the locking platform 81, and the locking spring 83 is sleeved on the locking column 811; the locking column 811 and the locking platform 81 are an integrally formed structure, and the locking spring 83 is conveniently installed through the setting of the locking column 811; the locking groove 226 is through-opened on the outer wall of the sensor housing 22; Among them, one end of the locking block 82 is connected to the locking spring 83, and the other end of the locking block 82 is inserted into the locking groove 226. In the specific implementation process, the locking block 82 and the locking spring 83 are welded and fixed.

[0040] It should be noted that the locking platform 81 and the terminal 10 can be an integrally formed structure, or the locking platform 81 and the terminal 10 can be fixedly connected; the locking block 82 is arranged in an L shape, and a pressing slope 821 is provided at one end of the locking block 82. The setting of the pressing slope 821 makes it convenient for the user to press and push the locking block 82 to move; a guide slope 822 is provided at one end of the locking block 82 inserted into the locking groove 226. The setting of the guide slope 822 facilitates the smooth insertion of the locking block 82 into the locking groove 226.

[0041] When the sensor assembly 20 needs to be pulled out, the locking assembly 80 is unlocked, and the locking block 82 is pressed and pushed to move the locking block 82 away from the locking groove 226. The sensor assembly 20 is rotated 90 degrees and then pulled out, thereby realizing the disassembly of the sensor assembly 20.

[0042] The present invention provides a pluggable temperature sensor 21 device for a water sample conductivity cell, which is assembled using the following method: Install the second sealing ring 50 into the first mounting groove 15 of the terminal 10; Obtain the pre-installed sensor assembly 20 and reset assembly 30, install the first sealing ring 40 into the fourth sealing ring of the sensor housing 22, and install the third sealing ring 60 into the second installation groove 311 of the reset assembly 30; The reset assembly 30 with the third sealing ring 60 is installed in the cavity 12 and bonded and packaged by the second adhesive layer 70, and the third flow channel 333 is connected with the first flow channel 11 and the second flow channel 13 respectively; When the sensor assembly 20 is needed, the sensor assembly 20 with the first sealing ring 40 is inserted into the cavity 12, and the sensor assembly 20 is installed in place by rotating the sensor assembly 20 90 degrees and inserting the locking block 82 of the locking assembly 80 into the locking groove 226; in this embodiment, the temperature sensor 21 performs real-time temperature detection on the water sample flowing through the first flow channel 11, and provides accurate temperature compensation for the conductivity measurement of the water sample; When the sensor assembly 20 needs to be pulled out, the locking assembly 80 is unlocked, and the locking block 82 is pressed and pushed to move the locking block 82 away from the locking groove 226.
