[0002] Normally, the PH probe of the PH detection device used in a water purifier is located in the water channel inside the water purifier. When the water flowing into the water purifier or the purified water flows inside the water channel, it will come into contact with the PH probe, and then the PH value of the water inside the water channel of the water purifier can be detected. However, since the probe is in contact with the water for a long time and lacks maintenance, its sensitivity will be reduced due to oxidation, resulting in inaccurate measurement values, which in turn shortens the life of the probe.

[0009] Wherein, the first detection hole and the second detection hole are both opened in the abutting portion, and the detection end of the probe is arranged on the side of the rotating disk close to the abutting portion and can rotate from the first predetermined position to the second predetermined position following the rotating disk.

[0010] In some embodiments, sealing rings are provided on the edges of the first detection hole and the second detection hole on a side close to the rotating disk.

[0011] In some embodiments, a side of the rotating disk close to the abutting portion is provided with an embedding groove for embedding the probe, the probe is disposed in the embedding groove, and one end of the probe opposite to the abutting portion does not protrude from the embedding groove.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 2 A PH detection device 100 is shown. It should be noted that the PH detection device 100 is used to detect the PH value of water in a waterway. The PH detection device 100 includes a shell 11, a movable mechanism 12 and a probe 13 for detecting the PH value of water quality in a water flow channel 02. A maintenance portion 111 and a waterway portion 112 are provided inside the shell 11. The maintenance portion 111 is provided with a maintenance cavity 01 for storing a maintenance liquid, and the waterway portion 112 is provided with a water flow channel 02 for water to flow through; the probe 13 is provided at the movable end of the movable mechanism 12, and the movable mechanism 12 is connected to the shell 11. The probe 13 can switch between a first predetermined position and a second predetermined position following the movable end of the movable mechanism 12; wherein, when the probe 13 is in the first predetermined position, the probe 13 is connected to the maintenance cavity 01, and when the probe 13 is in the second predetermined position, the probe 13 is connected to the water flow channel 02.

[0028] In actual use, the pH detection device 100 is only needed to detect the water body flowing through the water flow channel 02 when there is water flowing through the water flow channel 02. When there is no water flowing through the water flow channel 02, the pH detection device 100 is in an idle state. The pH detection device 100 provided in the present application, when it is necessary to detect the pH value of the water body in the water flow channel 02, the movable mechanism 12 drives the probe 13 to move from the maintenance chamber 01 to the inside of the water flow channel 02. When the pH detection device 100 is in an idle state (i.e., there is no water flowing through the water flow channel 02 or it is not necessary to detect the pH value of the water body in the water flow channel 02), the movable mechanism 12 drives the probe 13 to move from the maintenance chamber 01 to the inside of the water flow channel 02. When the pH detection device 100 is used for water flow detection), the movable mechanism 12 can drive the probe 13 to move to the maintenance chamber 01. The interior of the maintenance chamber 01 is used to store the maintenance liquid (reference liquid or reference solution). At this time, the maintenance liquid can be used to maintain the probe 13 of the pH detection device 100. Through the above process, compared with the traditional solution of always setting the probe 13 inside the water flow channel 02, the pH detection device 100 provided in the present application can maintain the probe 13 when the probe 13 is restricted, which improves the accuracy of the probe 13 and prolongs the service life of the probe 13.

[0029] The following will introduce the technical details of each component one by one.

[0030] In some embodiments, Figure 2As shown, the water flow part is provided with a buffer cavity 03, which is connected with the water flow channel 02. The probe 13 can be selectively connected with the buffer cavity 03 for contacting with the water body. The water flow inside the water flow channel 02 flows into the buffer cavity 03, and then flows out of the buffer cavity 03. Along the water flow direction, the water flow cross section of the buffer cavity 03 is larger than the water flow cross section 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 increases, so that the flow velocity of the water flow inside the buffer cavity 03 is reduced, and then compared with the probe 13 being set in the water flow channel 02, the impact of the water flow on the probe 13 set inside the buffer cavity 03 will be reduced, which helps to make the data measured by the probe 13 more accurate.

[0031] In order to further reduce the flow rate of water inside the buffer chamber 03, in other embodiments, a baffle is further provided inside the buffer chamber 03, and the baffle is arranged opposite to the water inlet of the buffer chamber 03. When the water flows into the buffer chamber 03, the baffle will block the water flow, thereby generating turbulence inside the buffer chamber 03 to further reduce the flow rate of the water inside the buffer chamber 03; and in order to allow the baffle to play a better role, the baffle is arranged upstream of the probe 13 along the direction of the water flow, so that the water flow can flow through the probe 13 after being slowed down by the baffle, thereby further reducing the impact of the water flow on the probe 13, and correspondingly improving the detection accuracy of the probe 13.

[0032] In some embodiments, Figure 2 , Figure 3 As shown, the inner wall of the above-mentioned curing chamber 01 is provided with a first detection hole 06, and the inner wall of the above-mentioned buffer chamber 03 is provided with a second detection hole 07. When the probe 13 is in the first predetermined position, the probe 13 is aligned with the first detection hole 06 for contact with 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 contact with the water flow. Through the above-mentioned 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 connected with the curing chamber 01 or the buffer chamber 03; as is known to all, the liquid cross-section of the hole is small, which is convenient for sealing around. When the probe 13 contacts the curing liquid or the water body, it does not need a very large contact liquid surface, so the above-mentioned first detection hole 06 and the second detection hole 07 are adopted to facilitate subsequent sealing. In addition to the above-mentioned effects, the first detection hole 06 and the second detection hole 07 both have a certain depth, which is also helpful in reducing the impact of the water flow on the probe 13.

[0033] In some embodiments, Figure 2 , Figure 3As shown, the movable mechanism 12 includes a rotating motor 121 and a rotating disk 122. The rotating disk 122 is connected to the rotating shaft of the rotating motor 121. A reduction mechanism is arranged inside the rotating motor 121. The reduction mechanism can reduce the load of the rotating motor 121 and increase the torque of the rotating motor 121, thereby extending the service life of the rotating motor 121 and facilitating the stable driving of the rotating disk 122 to rotate.

[0034] The housing 11 is provided with a supporting portion 113, and the rotating disk 122 is arranged opposite to the supporting portion 113 and is tightly fitted with the supporting portion 113 through a rotating clamping structure 04; specifically, the supporting portion 113 is provided with a smooth plane, and the rotating disk 122 can be sealed and fitted with the smooth plane, and the rotating clamping structure 04 is connected to the supporting portion 113 and can be tightly pressed against a side of the rotating disk 122 away from the supporting portion 113 to fix the rotating disk 122 on the supporting portion 113, and the supporting portion 113 and the rotating clamping structure 04 enclose a rotating space, and the rotating disk 122 can rotate in the rotating space in a state of being tightly fitted with the supporting portion 113. The first detection hole 06 and the second detection hole 07 are both opened in the supporting portion 113, and the detection end of the probe 13 is arranged on the side of the rotating disk 122 close to the supporting portion 113 and can rotate from the first predetermined position to the second predetermined position following the rotating disk 122. The switching of the probe 13 between the curing chamber 01 and the buffer chamber 03 can be achieved in the above manner.

[0035] In some embodiments, Figure 2 , Figure 3 As shown, the edges of the first detection hole 06 and the second detection hole 07 close to the rotating disk 122 are both provided with a sealing ring 14. Usually, the sealing ring 14 is made of elastic materials such as rubber and silicone. In the process of the rotating disk 122 and the abutting portion 113 abutting and fitting, the sealing ring 14 can further form a sealing structure for the edges of the first detection hole 06 and the second detection hole 07 to prevent the curing liquid or water from leaking along the gap between the rotating disk 122 and the abutting portion 113.

[0036] In order to allow the sealing ring 14 to better perform its sealing function, an annular groove is provided on the edge of the supporting portion 113 on the side close to the first detection hole 06 and the second detection hole 07 opposite to the rotating disk 122. The sealing ring 14 is embedded in the annular groove and protrudes from the annular groove. It can be understood that during the rotation of the rotating disk 122, the rotating disk 122 will generate friction on the sealing ring 14 to form a trend of driving the sealing ring 14 to move. The annular groove can limit the position of the seal to prevent the sealing ring 14 from moving with the rotating disk 122, causing the sealing ring 14 to shift and affect the sealing effect of the first detection hole 06 and the second detection hole 07.

[0037] In some embodiments, Figure 2 , Figure 3 As shown, the side of the rotating disk 122 close to the abutting portion 113 is provided with an embedding groove 05 for embedding the probe 13, and the probe 13 is arranged in the embedding groove 05, and one end of the probe 13 relative to the abutting portion 113 does not protrude from the embedding groove 05. In actual use, when the rotating disk 122 rotates, due to the structural friction between the rotating disk 122 and the abutting portion 113, a certain friction may be generated on the probe 13 during the rotation process, causing some adverse effects on the probe 13. The probe 13 is arranged inside the embedding groove 05 in the above manner. Since the probe 13 does not protrude from the embedding groove 05, an avoidance space is formed between the probe 13 and the abutting portion 113, thereby effectively preventing the rotating disk 122 from generating friction on the probe 13 during the rotation process, and thus protecting the probe 13.

[0038] In a specific application, two probes 13 may also be provided on the rotating disk 122. When one probe 13 moves to the curing chamber 01, the other probe 13 is located in the water flow channel 02, that is, the two probes 13 can work alternately without frequently switching the action state.

[0039] like Figure 1 As shown, the present application provides a water system, including a mineralized filter element 200 and the above-mentioned PH detection device 100, and the PH detection device 100 is connected to the mineralized filter element 200 through a pipeline. In actual use, water flows into the mineralized filter element 200 and the above-mentioned PH detection device 100 through the pipeline. Under the action of the above-mentioned PH detection device 100, the PH detection device 100 does not need to be maintained for a longer period of time, which reduces the maintenance cost and improves the purification efficiency of the water flow.

[0040] In some embodiments, along the water flow direction of the water system, the pH detection device 100 is disposed upstream or / and downstream of the mineralized filter element 200. The pH detection device 100 disposed upstream of the mineralized filter element 200 can detect the pH of the water flowing into the mineralized filter element 200, and the pH detection device 100 disposed downstream of the mineralized filter element 200 can detect the pH of the water flow purified by the mineralized filter element 200. The water system provided by the present application adopts the pH detection device 100, which can avoid the need for maintenance of the probe 13 for a longer period of time, thereby reducing maintenance costs and improving the purification efficiency of the water flow.

[0041] It should be noted that the water channel system provided in the present application may include a plurality of pH detection devices 100 , which may be respectively arranged upstream or downstream or both upstream and downstream of the mineralized filter element 200 along the water channel direction.

[0042] The present application provides a mineral water purifier that adopts the above-mentioned water system.

[0043] Specifically, according to the PH detection device 100 downstream of the mineralized filter element 200, it reflects the PH value of the water flow after passing through the mineralized filter element 200. In specific applications, the PH detection device 100 downstream of the mineralized filter element 200 can be set at the water outlet pipe of the mineral spring mineralized water purifier to detect the PH value of the outlet water.

[0044] In a specific application, by arranging the pH detection device 100 both upstream and downstream of the mineralized filter element 200, it can intuitively reflect the pH value change before and after the water flows through the mineralized filter element 200. In addition, by detecting the pH value change before and after the water flows through the mineralized filter element 200, it can also assist in judging the life of the mineralized filter element 200, and can conveniently adjust the pH value of the outlet water.

[0045] In some embodiments, the mineral water purifier further includes a display device, which is electrically connected to the pH detection device 100 to display the pH data detected by the probe 13, so that the staff can read and understand the pH value of the water body. The display device can be a display screen or a pointer set in the mineral water purifier.

[0046] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
