[0002] pH value, also known as concentration index or acid-base value, is a scale for the activity of hydrogen ions in a solution. It is used to measure the acidity or alkalinity of a solution. A pH meter is a testing instrument used to measure the acidity or alkalinity of a solution, i.e., the pH value.

[0003] A Chinese patent (CN213600625U) discloses a portable pH meter, comprising a body, a display screen, electrode interfaces, a protective cover, a probe, a control box, a circuit board, and a pH sensor. The body has a speaker on its front, with function buttons fixedly mounted on top of the speaker. A display screen is located above the function buttons. Electrode interfaces are fixedly mounted on both sides of the body. The control box has a circuit board on its top, with a wireless transmitter on its front. Second wires are located on both sides of the top of the control box, with the pH sensor fixedly mounted on top of each second wire. This invention, by incorporating a circuit board on the top of the control box and a wireless transmitter on its front, allows for remote data transmission of pH measurements via the wireless transmitter, thus improving user experience and work efficiency.

[0004] The pH meter mentioned above also has the following problems when in use: the length of its power cord is limited, which restricts the measurement range and makes the overall applicability of the pH meter low, resulting in product drawbacks.

[0005] Therefore, it is necessary to invent a pH meter that is easy to operate remotely to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a pH meter that is easy to operate remotely, in order to solve the problem mentioned in the background art that the pH meter has a limited power cord length during use, which limits the measurement range and makes the overall applicability of the pH meter low, resulting in product drawbacks.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pH meter that is easy to operate remotely, including a body, an electrode interface reserved at the front end of the body, and a wire fixedly connected to the electrode interface, and a probe installed at the end of the wire, a storage box movably fitted around the outer ring of the wire, and a through hole reserved inside the storage box, and the wire is wound and stored inside the storage box through a knob assembly.

[0008] Preferably, the storage box has two through holes inside, and the two through holes are connected to the inner cavity of the storage box. The two through holes are located on the same straight line, which facilitates the wires to pass through the storage box for storage.

[0009] Preferably, the knob assembly includes a rotating rod fixedly connected to the outer wall of the wire, and two connecting rods arranged in a ring are fixedly connected to the end wall of the rotating rod. The connecting rods are staggered on both sides of the wire, the connecting rods are fixedly connected to the wire, and the ends of the connecting rods away from the rotating rod are rotatably connected to the annular groove reserved inside the storage box to ensure the stability of the rotation of the connecting rods.

[0010] Preferably, the knob assembly further includes a threaded rod that is threadedly connected to the storage box, the threaded rod being threadedly connected to a pre-reserved threaded groove inside the storage box, and the threaded rod being slidably connected to a pre-reserved channel inside the rotating rod.

[0011] Preferably, the threaded rod has two protrusions fixedly connected to the outer wall of its end located in the channel, and the two protrusions are symmetrically distributed with reference to the central axis of the threaded rod. The threaded rod has a lever fixedly connected to its end located outside the storage box.

[0012] Preferably, the channel consists of a columnar channel and two strip channels connected to the columnar channel. The inner diameter of the columnar channel is larger than the outer diameter of the threaded rod. The inner wall of the strip channel is in contact with the outer wall of the protrusion to achieve a sliding connection. Both ends of the strip channel are closed. Twisting the threaded rod drives the rotating rod to rotate, so that the wire is wound around the outer ring of the connecting rod. The threaded rod that is threaded to the storage box is displaced when it rotates, and the channel provides displacement space for the threaded rod.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. In this utility model, longer wires can be stored and coiled up. This not only does not affect the subsequent use of the wires, but also prevents the wires from getting tangled, extending the service life of the wires and thus extending the service life of the device. At the same time, the wire length is adjustable, making it convenient for the device to be used in different situations.

[0015] 2. By twisting the end plate of the threaded rod, the threaded rod is driven to rotate. The threaded rod drives the rotating rod to rotate, so that the wire is wound around the outer ring of the connecting rod fixedly connected to the end wall of the rotating rod. The threaded rod, which is threadedly connected to the storage box, is displaced when it rotates. The channel provides displacement space for the threaded rod, ensuring the smooth progress of the winding work. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The pH meter shown includes a body 1, an electrode interface 2 is provided at the front end of the body 1, and a wire 3 is fixedly connected to the electrode interface 2. A probe 4 is installed at the end of the wire 3. A storage box 5 is movably fitted around the outer ring of the wire 3. A through hole 6 is provided inside the storage box 5. The wire 3 is wound and stored inside the storage box 5 through a knob assembly 7.

[0026] During use, the wire 3 can be stored (the two wires 3 appear to be combined into one, but are internally independent). This winding storage avoids tangling and extends the lifespan of the wire 3, thus extending the lifespan of the device, without affecting its subsequent use. The length of the wire 3 is also adjustable, facilitating use in different situations. The threaded rod 704 is rotated by the toggle plate 707 at its end, which in turn rotates the rotating rod 701, causing the wire 3 to be wound around the outer ring of the connecting rod 702, which is fixedly connected to the end wall of the rotating rod 701. The threaded rod 704, which is threadedly connected to the storage box 5, shifts during rotation. The channel 706 provides space for this shift. After adjusting the wire 3 to the appropriate length, the probe 4 is inserted into the liquid to be tested to detect the pH value. Simultaneously, the built-in sensor in the device 1 transmits the values ​​to the terminal for statistical analysis. The information transmission technology is a readily available and relatively mature technology, which will not be elaborated upon here.

[0027] To prevent the wire 3 from getting tangled and entering the storage box 5, the storage box 5 is equipped with two through holes 6 inside, which are connected to the inner cavity of the storage box 5 and are located on the same straight line. This allows the wire 3 to pass through the storage box 5 for storage. The inner cavity of the storage box 5 provides space for the wire 3 to be wound and stored. The wire 3 can pass through the through holes 6 to avoid getting tangled, which is convenient for subsequent storage.

[0028] To ensure convenient and quick winding and storage of the wire 3, the knob assembly 7 includes a rotating rod 701 fixedly connected to the outer wall of the wire 3. Two connecting rods 702 arranged in a ring are fixedly connected to the end wall of the rotating rod 701, and the connecting rods 702 are staggered on both sides of the wire 3. The connecting rods 702 are fixedly connected to the wire 3, and the end of the connecting rod 702 away from the rotating rod 701 is rotatably connected to the annular groove 703 reserved inside the storage box 5 to ensure the stability of the rotation of the connecting rod 702. The knob assembly 7 also includes a threaded rod 704 that is threadedly connected to the storage box 5. The threaded rod 704 is threadedly connected to the threaded groove 705 reserved inside the storage box 5, and the threaded rod 704 is slidably connected to the reserved channel 706 inside the rotating rod 701.

[0029] To facilitate the rotation of the threaded rod 704, two protrusions 708 are fixedly connected to the outer wall of the end of the threaded rod 704 located in the channel 706, and the two protrusions 708 are symmetrically distributed with reference to the central axis of the threaded rod 704. A lever 707 is fixedly connected to the end of the threaded rod 704 located outside the storage box 5.

[0030] Channel 706 consists of a columnar channel and two strip channels connected to the columnar channel. The inner diameter of the columnar channel is larger than the outer diameter of the threaded rod 704, which facilitates the sliding connection between the threaded rod 704 and the columnar channel. The inner wall of the strip channel is attached to the outer wall of the protrusion 708 to achieve a sliding connection. Both ends of the strip channel are in a closed state.

[0031] The threaded rod 704 is twisted, and the protrusion 708 fixedly connected to the end of the threaded rod 704 matches the channel 706. In this way, the rotation of the threaded rod 704 drives the rotation rod 701 to rotate, so that the wire 3 is wound around the outer ring of the connecting rod 702 fixedly connected to the end wall of the rotation rod 701. At the same time, the threaded rod 704, which is threadedly connected to the storage box 5, is displaced when it rotates, and the channel 706 provides displacement space for the threaded rod 704.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
