[0018] Continue to refer to Figures 1 to 6 As shown, the mounting housing 1 has a first cavity for accommodating components such as the battery bracket 2 and the main board 4. The battery bracket 2 is used to fix the battery. After installing the battery (two or four batteries can be installed) and covering it with the battery cover 6, the negative electrode spring 3 contacts the negative electrode of the battery, the positive electrode of the battery contacts the positive electrode spring 7, the negative electrode spring 3 is connected to the main board 4, and the positive electrode spring 7 contacts the spring pin 41 and is connected to the main board 4, thus forming an electrical circuit to supply power to the main board 4. The probe 5 is installed at the bottom of the mounting housing 1 for contacting and testing the water sample (the probe 5 and the main board 4 can use existing devices). In this embodiment, the test pen uses a replaceable battery, which is convenient to use, low in cost, and suitable for most consumers compared to conventional rechargeable water quality test pens.

[0019] Meanwhile, in this embodiment, a first mounting hole penetrating into the first cavity is also provided on one side of the mounting housing 1, and a display screen 13 connected to the motherboard 4 is also installed in the first mounting hole; a function button 14 connected to the motherboard 4 is also installed on one side of the mounting housing 1; a communication interface 42 is also provided on the side of the spring pin 41 on the motherboard 4. The display screen 13 is connected to the motherboard 4 and can display water quality test results, so that users can intuitively obtain water quality information, improving the practicality and user experience of the test pen. The function button 14 includes a power switch, page turning button, etc., which is convenient for user operation. The function button 14 adopts a touch button, which can not only meet the needs of consumers, but also improve waterproofness. It is also equipped with a communication interface 42, which can facilitate the inspection, upgrade and debugging of the motherboard 4 without disassembling it, which is convenient for after-sales maintenance.

[0020] In addition, a sealing ring is fitted on the probe 5, and a groove is formed on the outer wall of the probe 5 housing in the circumferential direction. The sealing ring is embedded in the groove to achieve side sealing. At the same time, a dotting groove is left at the edge of the probe 5 housing for applying adhesive, which further improves the waterproof performance of the test pen. In a preferred embodiment, three silicone sleeves 8 are also included. The three silicone sleeves 8 are respectively fitted on the mounting housing 1, the probe 5 and the battery cover 6. The silicone sleeves 8 can play a role in waterproofing, dustproofing and shock resistance, improving the user experience of the test pen.

[0021] Preferably, the probe 5 includes a probe base 51 installed at the bottom opening of the mounting housing 1, a drive board 52 installed inside the probe base 51, two detection probes 53 connected to the drive board 52, and a connector 54 connecting the drive board 52 and the main board 4; the bottom of the probe base 51 has a first insertion hole, and one end of the detection probe 53 is arranged through the first insertion hole; the bottom of the probe base 51 is also connected to a probe bracket 55, and the four sides of the probe bracket 55 have first through holes; one end of the detection probe 53 has a planar structure and is flush with the plane of the bottom of the probe base 51; the probe 5 also includes a temperature probe 56 connected to the drive board 52; the bottom of the probe base 51 also has a second insertion hole, and the temperature probe 56 is inserted into the second insertion hole; the bottom of the temperature probe 56 also has a planar structure and is flush with the plane of the bottom of the probe base 51.

[0022] When probe 5 is inserted into the liquid, the liquid flows through the first through hole into probe holder 55 and comes into contact with two detection probes 53 (detection probes 53 are energized to detect water quality). The two detection probes 53 adopt a spring needle structure, and the bottom of detection probe 53 is a flat structure, and the bottom plane is flush with the plane of the bottom of probe seat 51. This design makes the entire detection cavity flat and simple, avoiding the adhesion of air bubbles (general water quality test pens have probes that extend to a certain length, which are easy to trap air bubbles). At the same time, a temperature probe 56 is also provided (the structural design of temperature probe 56 is the same as that of detection probe 53), which can detect the temperature of the liquid at the same time.

A first locking hole 62 is also provided on the upper part of one side of the mounting housing 1, corresponding to the elastic buckle. The battery cover 6 is snapped onto the mounting housing 1 via the elastic buckle and the first locking hole 62. The battery cover 6 is snapped onto the mounting housing 1 in a snap-fit ​​manner, making battery replacement convenient.

[0024] Preferably, in this embodiment, the elastic buckle includes a first connecting plate 63, a second connecting plate 64, and a third connecting plate 65; the upper part of the first connecting plate 63 is connected to the inner wall of the first notch; the second connecting plate 64 has a semi-circular cross-section, and the top of one end of the second connecting plate 64 is connected to the bottom of the first connecting plate 63; the third connecting plate 65 is arranged on one side of the first connecting plate 63, and the bottom of the third connecting plate 65 is connected to the top of the other end of the second connecting plate 64; a first locking block 66 for locking into the first locking hole 62 is connected to the lower part of one side of the third connecting plate 65 at the location corresponding to the first locking hole 62; a second locking block 68 is also connected to the other side of the battery cover 6, and a second locking hole 12 is also provided on the upper part of the other side of the mounting housing 1 at the location corresponding to the second locking block 68.

[0025] When installing the battery cover 6, first tilt the lower part of the battery cover 6 and insert it into the top opening of the mounting housing 1, so that the second locking block 68 is aligned with the second locking hole 12 and then inserted into the second locking hole 12. Then, press the third connecting plate 65 so that the third connecting plate 65 retracts into the first notch, and then insert the battery cover 6 completely into the mounting housing 1. Then, align the first locking block 66 with the first locking hole 62, and then release the third connecting plate 65 so that the first locking block 66 is inserted into the first locking hole 62. At this point, the battery cover 6 is installed. It is simple and convenient. When removing the battery cover 6 to replace the battery, simply press the third connecting plate 65 so that the first locking block 66 disengages from the first locking hole 62, and then pull it upwards. The operation is convenient and quick.

[0026] In order to facilitate pressing the third connecting plate 65, preferably, a pressing block 67 is also connected to the upper part of one side of the third connecting plate 65, and a clearance notch 11 is also provided on the top side of the mounting housing 1 corresponding to the pressing block 67.

[0027] In one embodiment, a plug block 611 is also connected inside the first mounting cavity 61, and a first plug groove 612 is formed at the bottom of the plug block 611; a plug portion 71 extends upward from the top of the positive electrode spring 7, and the plug portion 71 is inserted into the first plug groove 612; a plug post 613 is also connected inside the first mounting cavity 61, and a plug hole 72 is formed on the positive electrode spring 7 corresponding to the plug post 613, and the plug post 613 is arranged through the plug hole 72. The plug portion 71 of the positive electrode spring 7 is inserted into the first plug groove 612, and the plug post 613 passes through the plug hole 72 of the positive electrode spring 7. This structural design can ensure the stability of the positive electrode spring 7 installation, thereby ensuring good electrical contact with the spring pin 41.
