[0003] The existing water pH measuring device inserts a measuring probe into the water body to measure the pH of the water body. However, when continuously measuring different water bodies, the residual water stains on the measuring probe will affect the next pH measurement result, resulting in inaccurate measurement.
[0004] Therefore, a portable water pH measuring device is now developed that can clean the stains on the measuring probe and avoid inaccurate pH value measurement when performing continuous pH measurement on different water bodies. Utility Model Content

The inner side of the movable block is connected to the dirt removal cotton. The dirt removal cotton is in contact with the measuring probe. When the movable block is pulled downward, the spring is stretched to make the dirt removal cotton slide downward on the measuring probe to scrape off the water stains on the measuring probe. Then, the spring rebounds to pull the dirt removal cotton to slide upward on the measuring probe to absorb the remaining water stains on the measuring probe into the dirt removal cotton.
[0008] Preferably, a protection mechanism is also included, which includes a first clamping block, a protection tube and a second clamping block. The lower middle part of the shell is connected to two left and right first clamping blocks, the protection tube is clamped between the first clamping blocks, and the inside of the protection tube is connected to two left and right second clamping blocks, so that the measuring probe is clamped and matched with the first clamping block, and the protection tube is fixed on the first clamping block. Then, the measuring probe is rotated to rotate the fixing block on the connecting piece until the measuring probe is clamped and matched with the second clamping block, so that the measuring probe is fixed inside the protection tube.
[0009] Preferably, a hanging ring is provided on the shell for easy carrying.
[0010] Preferably, the elastic member is a spring.
[0011] Preferably, the first clamping block is an arc-shaped structure.
[0012] The beneficial effects of the utility model are as follows: 1. The utility model makes the dirt-removing cotton slide downward on the measuring probe to scrape off the water stains on the measuring probe, and then makes the spring rebound to pull the dirt-removing cotton to slide upward on the measuring probe, and absorbs the remaining water stains on the measuring probe into the dirt-removing cotton, thereby achieving the effect of being able to clean the stains on the measuring probe when performing continuous pH measurements on different water bodies, thereby avoiding inaccurate pH value measurements.

DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0019] A portable water pH measuring device, such as Figure 1As shown, it includes a shell 1, a display screen 2, a connecting piece 3, a measuring probe 4 and a cleaning mechanism 5. The display screen 2 is connected to the upper right side of the shell 1. The shell 1 is provided with a hanging ring for easy carrying. The lower right side of the shell 1 is connected to the connecting piece 3. The lower side of the connecting piece 3 is rotatably connected to the measuring probe 4. The measuring probe 4 is provided with a cleaning mechanism 5.
[0020] like Figure 1 and Figure 2 As shown, the dirt removal mechanism 5 includes a fixed block 51, a moving block 52, an elastic member 53 and a dirt removal cotton 54. The fixed blocks 51 are connected to the front and rear sides of the upper part of the measuring probe 4. The moving block 52 is connected to the lower side of the fixed block 51 through an elastic member 53. The elastic member 53 is a spring. The inner side of the moving block 52 is connected to the dirt removal cotton 54, and the dirt removal cotton 54 is in contact with the measuring probe 4.
[0021] When using the utility model, first, insert the measuring probe 4 into the water body to be measured by holding the shell 1, and the pH value of the water body will be displayed on the display screen 2. The movable block 52 is connected to the fixed block 51 by a spring. When it is necessary to continuously measure the pH value of different water bodies, pull the movable block 52 downward, the spring is stretched, and the decontamination cotton 54 slides downward on the measuring probe 4 to scrape off the water stains on the measuring probe 4. Then, the spring rebounds and pulls the decontamination cotton 54 to slide upward on the measuring probe 4 to absorb the remaining water stains on the measuring probe 4 into the decontamination cotton 54, thereby playing a role in cleaning the stains on the measuring probe 4 when performing continuous pH measurements on different water bodies, thereby avoiding inaccurate pH value measurements.
[0022] like Figure 1 and Figure 3 As shown, a protection mechanism 6 is also included, which includes a first clamping block 61, a protection tube 62 and a second clamping block 63. The lower middle side of the shell 1 is connected to the left and right first clamping blocks 61. The first clamping blocks 61 are arc-shaped for easy clamping. The protection tube 62 is clamped between the first clamping blocks 61, and the inside of the protection tube 62 is connected to the left and right second clamping blocks 63.
[0023] The protection mechanism 6 of the device can be used to protect the measuring probe 4. After the pH measurement of the water body is completed, the measuring probe 4 is engaged with the first clamping block 61, and the protection tube 62 is fixed on the first clamping block 61. Then, the measuring probe 4 is rotated to make the fixing block 51 rotate on the connecting member 3 until the measuring probe 4 is engaged with the second clamping block 63, so that the measuring probe 4 is fixed inside the protection tube 62, thereby protecting the measuring probe 4 and preventing the measuring probe 4 from being damaged.
[0024] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
