The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0026] The application will be further described below in conjunction with the drawings.

[0027] As Figure 2 shown in a PH detection device 100, it should be pointed out that the PH detection device 100 is used for detecting the PH value of the water body in the waterway, the PH detection device 100 comprises a shell 11, a moving mechanism 12 and a probe 13 for detecting the PH value of the water quality in the water flow channel 02, the shell 11 is internally provided with a maintenance part 111 and a waterway part 112, the maintenance part 111 is provided with a maintenance cavity 01 for storing the maintenance liquid, and the waterway part 112 is provided with a water flow channel 02 for the water body to flow through; the probe 13 is arranged at the moving end of the moving mechanism 12, the moving mechanism 12 is connected with the shell 11, and the probe 13 can be switched between the first predetermined position and the second predetermined position along with the moving end of the moving mechanism 12; wherein when the probe 13 is at the first predetermined position, the probe 13 is in communication with the maintenance cavity 01, and when the probe 13 is at the second predetermined position, the probe 13 is in communication with the water flow channel 02.

[0028] In actual use, only when the water flow channel 02 has water flow passing through inside, the PH detection device 100 needs to detect the water body flowing through, and when the water flow channel 02 has no water flow passing through inside, the PH detection device 100 is in an idle state; the PH detection device 100 provided by the present application, when the PH value of the water body inside the water flow channel 02 needs to be detected, the moving mechanism 12 drives the probe 13 to move from the maintenance cavity 01 to the inside of the water flow channel 02, when the PH detection device 100 is in an idle state (i.e. no water flow passes through the water flow channel 02 or no water flow needs to be detected), the moving mechanism 12 can drive the probe 13 to move to the maintenance cavity 01, the inside of the maintenance cavity 01 is used for storing the maintenance liquid (reference liquid or reference solution), at this time, the probe 13 of the PH detection device 100 can be maintained by the maintenance liquid, through the above process, compared with the traditional scheme of always arranging the probe 13 inside the water flow channel 02, the PH detection device 100 provided by the present application can maintain the probe 13 when the probe 13 is limited, which improves the accuracy of the probe 13 and also prolongs the service life of the probe 13.

[0029] The technical details of each component will be introduced one by one as follows.

[0030] In some embodiments, as Figure 2As shown, the waterway part 112 is provided with a buffer cavity 03, which is in communication with the water flow channel 02, and the probe 13 is selectively in communication with the buffer cavity 03 for contacting the water body, and the water flow in the water flow channel 02 flows into the buffer cavity 03 and then flows out of the buffer cavity 03. In the water flow direction, the water flow cross section of the buffer cavity 03 is larger than that of the water flow channel 02. Under the action of the buffer cavity 03, according to the characteristics of the fluid, when the water flow enters the buffer cavity 03 from the water flow channel 02, the water flow cross section is increased, so that the flow rate of the water flow in the buffer cavity 03 is reduced, and the probe 13 is arranged in the water flow channel 02, so that the impact of the water flow on the probe 13 arranged in the buffer cavity 03 is reduced, which helps to make the data measured by the probe 13 more accurate.

[0031] In order to further reduce the flow rate of the water flow in the buffer cavity 03, in some embodiments, the inside of the buffer cavity 03 is further provided with a baffle, which is arranged opposite to the water inlet of the buffer cavity 03, and when the water flow flows into the buffer cavity 03, the baffle blocks the water flow, and then generates turbulence in the buffer cavity 03 to further reduce the flow rate of the water flow in the buffer cavity 03; and in order to make the baffle play a better role, the baffle is arranged upstream of the probe 13 in the water flow direction, so that the water flow is slowed down by the baffle and then flows through the probe 13, further reducing the impact of the water flow on the probe 13, and correspondingly improving the accuracy of the probe 13.

[0032] In some embodiments, as shown in Figure 2 , Figure 3 The inner wall of the buffer cavity 03 is provided with a second detection hole 07, and when the probe 13 is in the first predetermined position, the probe 13 is aligned with the first detection hole 06 for contacting the curing liquid, and when the probe 13 is in the second predetermined position, the probe 13 is aligned with the second detection hole 07 for contacting the water flow. Through the above design, the probe 13 is switched between the first detection hole 06 and the second detection hole 07 to change whether the probe 13 is in communication with the buffer cavity 03 or the buffer cavity 03; as known, the liquid cross section of the hole is small, which is convenient for sealing around, and the probe 13 does not need a very large contact liquid surface when contacting the curing liquid or the water body, so the above-mentioned first detection hole 06 and second detection hole 07 are convenient for subsequent sealing. In addition to the above effects, the first detection hole 06 and the second detection hole 07 have a certain depth, which also helps to reduce the impact of the water flow on the probe 13.

[0033] In some embodiments, as shown in Figure 2 , Figure 3As shown, the above-mentioned activity mechanism 12 comprises a rotating motor 121 and a rotating disc 122, the rotating disc 122 is connected with the rotating shaft of the rotating motor 121, the inside of the rotating motor 121 is provided with a speed reduction mechanism, the speed reduction mechanism can reduce the load of the rotating motor 121 and also can improve the torque of the rotating motor 121, thereby can prolong the service life of the rotating motor 121 and also can conveniently stably drive the rotating disc 122 to rotate.

[0034] The above-mentioned shell 11 is provided with an abutting part 113, the rotating disc 122 is oppositely arranged with the abutting part 113 and is abuttingly fitted with the abutting part 113 through the rotating clamping structure 04; specifically, the abutting part 113 is provided with a smooth plane, the rotating disc 122 can be sealingly fitted with the smooth plane, the rotating clamping structure 04 is connected with the abutting part 113 and can be abuttingly fitted with the side face of the rotating disc 122 away from the abutting part 113 to fix the rotating disc 122 on the abutting part 113, the abutting part 113 and the rotating clamping structure 04 enclose a rotating space, the rotating disc 122 can rotate in the rotating space in the state of abuttingly fitting with the abutting part 113. The first detection hole 06 and the second detection hole 07 are both arranged on the abutting part 113, the detection end of the probe 13 is arranged on the side face of the rotating disc 122 close to the abutting part 113 and can follow the rotating disc 122 to rotate from the first predetermined position to the second predetermined position. Through the above-mentioned mode, the switching of the probe 13 between the maintenance cavity 01 and the buffer cavity 03 can be realized.

[0035] In some embodiments, as shown in Figure 2 , Figure 3 The edges of the first detection hole 06 and the second detection hole 07 close to one side of the rotating disc 122 are both provided with a sealing ring 14. Generally, the sealing ring 14 is made of elastic materials such as rubber and silica gel, in the process of abuttingly fitting the rotating disc 122 with the abutting part 113, the sealing ring 14 can further form a sealing structure on the edges of the first detection hole 06 and the second detection hole 07 to prevent the maintenance liquid or water from leaking out along the gap between the rotating disc 122 and the abutting part 113.

[0036] In order to make the sealing ring 14 better play the sealing role, the abutting part 113 is provided with a ring groove close to the edges of the first detection hole 06 and the second detection hole 07 relative to the rotating disc 122, the sealing ring 14 is embedded in the ring groove and protrudes from the ring groove; it can be understood that in the process of rotating the rotating disc 122, the rotating disc 122 will generate friction force on the sealing ring 14 to form the tendency of driving the sealing ring 14 to move, the ring groove can limit the position of the sealing ring 14 to prevent the sealing ring 14 from moving with the rotating disc 122, causing the sealing ring 14 to displace and affecting the sealing effect on the first detection hole 06 and the second detection hole 07.

[0037] In some embodiments, as shown in Figure 2 ,Figure 3 As shown, the rotating disc 122 is provided with an embedding groove 05 for embedding the probe 13 on the side close to the abutting part 113. The probe 13 is arranged in the embedding groove 05, and one end of the probe 13 relative to the abutting part 113 does not protrude from the embedding groove 05. In actual use, when the rotating disc 122 rotates, due to the structural friction between the rotating disc 122 and the abutting part 113, the probe 13 may also be subjected to a certain friction during rotation, which may cause some adverse effects on the probe 13. By arranging the probe 13 in the embedding groove 05 in the above manner, since the probe 13 does not protrude from the embedding groove 05, a clearance is formed between the probe 13 and the abutting part 113, thereby effectively preventing the rotating disc 122 from generating friction on the probe 13 during rotation, which protects the probe 13.

[0038] In specific applications, two probes 13 can also be arranged on the rotating disc 122. One probe 13 is arranged to move to the maintenance cavity 01, and the other probe 13 is arranged in the water flow channel 02, that is, the two probes 13 can work alternately without frequent switching of the action state.

[0039] As shown in the drawings, Figure 1 The waterway system provided by the application comprises a mineralization filter element 200 and the PH detection device 100. The PH detection device 100 is connected to the mineralization filter element 200 through a pipeline. In actual use, water flows into the mineralization filter element 200 and the PH detection device 100 through the pipeline. Under the action of the PH detection device 100, the PH detection device 100 can be maintained for a longer time without maintenance, which reduces the maintenance cost and improves the purification efficiency of the water flow.

[0040] In some embodiments, the PH detection device 100 is arranged upstream or downstream of the mineralization filter element 200 along the direction of the water flow in the waterway system. The PH detection device 100 arranged upstream of the mineralization filter element 200 can detect the PH of the water flow flowing into the mineralization filter element 200, and the PH detection device 100 arranged downstream of the mineralization filter element 200 can detect the PH of the water flow purified by the mineralization filter element 200. The waterway system provided by the application can maintain the probe 13 for a longer time without maintenance, which reduces the maintenance cost and improves the purification efficiency of the water flow.

[0041] It should be noted that the waterway system provided by the application can comprise a plurality of PH detection devices 100, which can be arranged upstream or downstream of the mineralization filter element 200 or upstream and downstream of the mineralization filter element 200 along the direction of the water flow.

[0043] Specifically, according to the PH detection device 100 downstream of the mineralization filter element 200, the PH value of the water flow after passing through the mineralization filter element 200 is embodied, and in specific applications, the PH detection device 100 downstream of the mineralization filter element 200 can be arranged at the water outlet pipeline of the mineral spring mineralization water purifier, for detecting the PH value of the outlet water.

[0044] In specific applications, by arranging the PH detection device 100 upstream and downstream of the mineralization filter element 200, the change of the PH value of the water flow before and after passing through the mineralization filter element 200 can be directly embodied. In addition, by detecting the change of the PH value of the water flow before and after passing through the mineralization filter element 200, the service life of the mineralization filter element 200 can also be judged, and the PH value of the outlet water can be conveniently controlled.

[0045] In some embodiments, the above-mentioned mineral spring mineralization water purifier further comprises a display device electrically connected with the PH detection device 100 to display the PH data detected by the probe 13, so as to facilitate the staff to read and understand the PH value of the water body. The display device can be a display screen or a pointer arranged on the mineral spring mineralization water purifier.
