Detailed Implementation

[0036] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] This invention provides a pluggable temperature sensor 21 for a water sample conductivity cell, such as... Figure 1-7 As shown, it includes: terminal 10, sensor assembly 20 and reset assembly 30. Terminal 10 is used to be installed on the water sample conductivity cell. Sensor assembly 20 is detachably connected to terminal 10. Reset assembly 30 is elastic.

[0040] Terminal 10 has a first flow channel 11, a cavity 12, and a second flow channel 13 that pass through it sequentially. Sensor assembly 20 and reset assembly 30 are both installed in the cavity 12. Sensor assembly 20 includes a temperature sensor 21. One end of temperature sensor 21 is located between the first flow channel 11 and the second flow channel 13. One end of sensor assembly 20 is pressed against one end of reset assembly 30. Reset assembly 30 is fixedly installed in the cavity 12 relative to the end of temperature sensor 21. In this embodiment, sensor assembly 20 is detachably connected to terminal 10, which facilitates installation and maintenance and improves the convenience and operability of the device.

[0041] In this embodiment, the water sample to be tested flows out of the first flow channel 11, 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, which connects the first flow channel 11 and the second flow channel 13 after the sensor assembly 20 is disassembled. In this embodiment, because the reset assembly 30 is elastic, it can automatically reset after the sensor assembly 20 is disassembled, ensuring that the water sample flow path is not interrupted and the continuous operation of the equipment is guaranteed.

[0042] It should be noted that the pluggable temperature sensor 21 device for a water sample conductivity cell provided by the present invention allows for temperature detection of the water sample flowing out of the first flow channel 11, passing through the gap between the sensor assembly 20 and the reset assembly 30, and flowing into the second flow channel 13. Since the sensor assembly 20 is detachably connected to the terminal 10, it can be disassembled and replaced individually. 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 of non-detachable sensors in the prior art.

[0043] like Figure 3 As shown, the sensor assembly 20 also includes a sensor housing 22, one end of which is pressed against 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 together by a first adhesive layer 23. In a specific implementation, the sensor housing 22 is provided with a third mounting groove 224 for accommodating the first adhesive layer 23; the first adhesive layer 23 is epoxy resin or other adhesive.

[0044] like Figure 3 and Figure 7 As shown, the outer wall of the sensor housing 22 is provided with a rotating locking block 221, and a slot 14 is provided through the cavity 12 to rotate and engage with the rotating locking block 221. In the specific implementation, the number of rotating locking blocks 221 and slots 14 is set to two, and the rotating locking blocks 221 and slots 14 correspond one-to-one. The two rotating locking blocks 221 are distributed opposite to each other on the outer wall of the sensor housing 22, and the two slots 14 are distributed opposite to each other in the cavity 12.

[0045] A first sealing ring 40 is fitted onto the sensor housing 22, and the first sealing ring 40 abuts against the inner wall of the cavity 12. In a specific implementation, the outer wall of the sensor housing 22 is provided with a fourth mounting groove 225, and the first sealing ring 40 is fitted into the fourth mounting groove 225. The first sealing ring 40 is made of silicone or rubber and is O-shaped. Through the sealing effect of the first sealing ring 40, the sensor assembly 20 and the terminal 10 can be effectively sealed.

[0046] It should be noted that when the sensor assembly 20 needs to be installed into the terminal 10, the sensor assembly 20 can be installed in place by inserting the rotating locking block 221 into the slot 14 and rotating the sensor housing 22 90 degrees clockwise or counterclockwise. For example, the rotating locking block 221 of the sensor housing 22 of the present invention is inserted into the slot 14, and then rotated 90 degrees counterclockwise to install the sensor housing 22 in place. Conversely, after rotating the sensor housing 22 90 degrees clockwise, the sensor housing 22 can be pulled out from the terminal 10, thereby realizing the quick installation and removal of the sensor assembly 20.

[0047] like Figure 3 and Figure 7 As shown, a pressing platform 222 is provided at one end of the sensor housing 22 located within the cavity 12, and the pressing platform 222 contacts one end of the reset assembly 30; a gap is provided between the end of the temperature sensor 21 located within the cavity 12 and the end of the reset assembly 30. In a specific implementation, two pressing platforms 222 are provided, and the two pressing platforms 222 are positioned opposite each other at one end of the sensor housing 22, with the sensor housing 22 and the pressing platforms 222 being integrally formed; by providing the pressing platforms 222, the pressing platforms 222 contact one end of the reset assembly 30, preventing the reset assembly 30 from directly contacting the temperature sensor 21, thus effectively protecting the temperature sensor 21.

[0048] like Figure 3-7 As shown, a number of grooves 223 are distributed circumferentially on the outer wall of one end of the sensor housing 22. In specific implementation, the grooves 223 are evenly spaced. The grooves 223 enhance the friction between the user's hand and the sensor housing 22, making it easier for the user to rotate the sensor housing 22, thus facilitating convenient use and saving time and effort.

[0049] like Figure 3 and Figure 6 As shown, a first mounting groove 15 is formed through the cavity 12, and a second sealing ring 50, which is fitted into the sensor assembly 20, is installed in the first mounting groove 15. After the sensor assembly 20 is rotated out, the end of the reset assembly 30 near the temperature sensor 21 springs back through the second sealing ring 50. In specific implementation, the second sealing ring 50 is fitted into the sensor housing 22. The second sealing ring 50 is made of silicone or rubber and is O-shaped; the sealing effect of the second sealing ring 50 effectively seals the device.

[0050] It should be noted that when the sensor assembly 20 is in 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; thus ensuring that the device can effectively seal in two different states.

[0051] 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 arranged sequentially. 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.

[0052] 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 disposed at one end of the reset rod 33 relative to the reset mounting platform 31, and one end of the sensor assembly 20 is in contact with the reset rod 33. In specific implementation, the reset rod 33 is T-shaped.

[0053] It should be noted that when the sensor assembly 20 is installed on the terminal 10 for detection, the crimping station 222 presses the reset rod 33, causing the reset rod 33 to press the reset spring 32. When the sensor assembly 20 is disassembled, the crimping station 222 separates from the reset rod 33, and the reset rod 33 rebounds under the elastic force of the reset spring 32. One end of the reset rod 33 passes through the second sealing ring 50, aligning and connecting the third flow channel 333 with the first flow channel 11 and the second flow channel 13, ensuring that the water sample circuit is not interrupted and avoiding the interruption of the operation of the water sample conductivity cell.

[0054] like Figure 3-5 As shown, a first blocking surface 121 is provided inside the cavity 12, which is used to limit the springback stroke of the reset rod 33; a mounting post 331 is provided inside the reset rod 33, and the reset spring 32 is sleeved on the mounting post 331. In specific implementation, the mounting post 331 and the reset rod 33 are integrally formed; the springback stroke of the reset rod 33 can be limited by the setting of the first blocking surface 121.

[0055] like Figure 3-5 As shown, the reset mounting platform 31 is provided with a second mounting groove 311, and a third sealing ring 60 that is sleeved with the reset rod 33 is installed in the second mounting groove 311; the third sealing ring 60 can be positioned and installed by the second mounting groove 311; the third sealing ring 60 is made of silicone or rubber and is O-shaped; the third sealing ring 60 effectively seals the reset assembly 30 through its sealing effect.

[0056] The reset mounting platform 31 has a sliding groove 312 that extends through one end face of the reset mounting platform 31. The outer wall of the reset rod 33 has a slider 332 that slides in cooperation with the sliding groove 312. In specific implementation, there are two sliding grooves 312 and two sliders 332. The two sliding grooves 312 are distributed opposite each other in the reset mounting platform 31, and the two sliders 332 are respectively opposite each other on the outer wall of the reset rod 33. The sliders 332 and the reset rod 33 are integrally formed. The cavity 12 has a first mounting surface 122 and a first positioning surface 313 that is 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.

[0057] It should be noted that the slider 332 and the groove 312 facilitate the positioning and sliding of the reset rod 33 on the reset mounting platform 31.

[0058] like Figure 3 As shown, the reset mounting platform 31 is bonded and encapsulated within the cavity 12 by a second adhesive layer 70. It should be noted that the second adhesive layer 70 is epoxy resin or other adhesive. The second adhesive layer 70 allows the reset assembly 30 to be quickly encapsulated within the cavity 12.

[0059] like Figure 8 and Figure 9 As shown, a locking component 80 is provided on terminal 10, which is used to lock the sensor assembly 20. It should be noted that the locking component 80 is provided to prevent the user or others from accidentally rotating the sensor assembly 20 and affecting its normal operation.

[0060] like Figure 8 and Figure 9 As shown, the locking assembly 80 includes a locking platform 81 mounted on the terminal 10, a locking block 82 passing through the locking platform 81, a locking spring 83 installed inside the locking platform 81, and a locking groove 226 on the sensor assembly 20. In a specific implementation, a locking post 811 is provided inside the locking platform 81, and the locking spring 83 is sleeved on the locking post 811. The locking post 811 and the locking platform 81 are integrally formed, and the locking post 811 facilitates the installation of the locking spring 83. The locking groove 226 is formed through the outer wall of the sensor housing 22.

[0061] 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 practice, the locking block 82 and the locking spring 83 are welded together and fixed.

[0062] It should be noted that the locking platform 81 and the terminal 10 can be integrally formed, or the locking platform 81 and the terminal 10 can be fixedly connected; the locking block 82 is L-shaped, and one end of the locking block 82 is provided with a pressing slope 821. The pressing slope 821 makes it easy for the user to press and push the locking block 82 to move; the end of the locking block 82 that is inserted into the locking groove 226 is provided with a guide slope 822. The guide slope 822 makes it easy for the locking block 82 to be smoothly inserted into the locking groove 226.

[0063] When it is necessary to remove the sensor assembly 20, the locking assembly 80 is unlocked, the locking block 82 is pressed and pushed to move the locking block 82 away from the locking groove 226, and the sensor assembly 20 is rotated 90 degrees and then pulled out, thus removing the sensor assembly 20.

[0064] The present invention provides a pluggable temperature sensor 21 for a water sample conductivity cell, which is assembled using the following method:

[0065] Insert the second sealing ring 50 into the first mounting groove 15 of the terminal 10;

[0066] 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 mounting groove 311 of the reset assembly 30;

[0067] The reset assembly 30 with the third sealing ring 60 is installed into the cavity 12 and bonded and sealed by the second adhesive layer 70. The third flow channel 333 is connected to the first flow channel 11 and the second flow channel 13 respectively.

[0068] When the sensor assembly 20 is needed, the sensor assembly 20 with the first sealing ring 40 is inserted into the cavity 12. The sensor assembly 20 is rotated 90 degrees and the locking block 82 of the locking assembly 80 is inserted into the locking groove 226 to install the sensor assembly 20 in place. In this embodiment, the temperature sensor 21 performs real-time temperature detection on the water sample flowing through the first flow channel 11 to provide accurate temperature compensation for the water sample conductivity measurement.

[0069] When it is necessary to remove the sensor assembly 20, the locking assembly 80 is unlocked, the locking block 82 is pressed and pushed to move the locking block 82 away from the locking groove 226, and the sensor assembly 20 is rotated 90 degrees and then pulled out, thus removing the sensor assembly 20.

[0070] Working principle: The sensor assembly 20 is installed in the terminal 10. The reset rod 33 is squeezed by the crimping table 222, which drives the reset spring 32 to compress, so that the third flow channel 333 is separated from the first flow channel 11 and the second flow channel 13 respectively. The water sample to be tested 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. The temperature of the water sample flowing out of the first flow channel 11 can be detected by the temperature sensor 21.

[0071] After the sensor assembly 20 is disassembled, the pressing platform 222 separates from the reset rod 33. The reset rod 33 rebounds under the elastic force of the reset spring 32. 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 avoiding the interruption of the operation of the water sample conductivity cell.

[0072] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
