Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a portable PH-EC measuring instrument. Background Art

[0002] Water quality testing is a process used to assess the content and properties of various substances in a body of water. These substances may include dissolved chemicals, microorganisms, suspended matter, and other contaminants in the water. Water quality testing is usually performed by collecting water samples and subjecting them to laboratory analysis. These analyses can include physical properties such as color, turbidity, and temperature, chemical composition such as pH, redox potential, and dissolved oxygen, and biological indicators such as the presence of bacteria and algae.

[0003] For example, a portable pH value detector disclosed in the authorization announcement number CN219122192U has a detector, a first probe is fixedly arranged on the top of the detector, a second probe is fixedly arranged on one side of the first probe, a display screen is fixedly arranged on the front face of the detector, a control panel is fixedly arranged on the bottom of the display screen, and a third protective cover is arranged on the periphery of the detector. After adopting the above technical scheme, the beneficial effect of the utility model is as follows: the portable pH value detector is provided with a third protective cover, and an elastic band is provided on the third protective cover, so that the user can put the detector in the protective cover, and then put the protective cover on the shoulder, which can prevent the detector from being squeezed and inconvenient to take out when it is placed in the pocket. This design cleverly solves this problem.

[0004] Although the above patent allows the user to put the detector in a protective cover, the head of the detection pen is usually covered with a pen cover, which is used to protect the detection head. However, in daily use, the pen cover needs to be removed, which can easily cause the pen cover to be lost. Utility Model Content

[0005] The purpose of the utility model is to provide a portable PH-EC measuring instrument to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A portable PH-EC measuring instrument, comprising

[0008] A shell, one end of which is fixedly connected to a protective shell, a water quality measuring pen is movably installed inside the shell, one end of the water quality measuring pen is provided with a detection head, and the detection head is movably sleeved with the protective shell;

[0009] The side shells are symmetrically arranged at the middle outer walls of both sides of the shell, and a rotating mechanism is arranged between the side shells and the water quality measuring pen.

[0010] Preferably, the rotating mechanism comprises a guide groove and a slider, the guide groove is opened between the outer shell and the middle part of the side shell, and the slider is movably connected to the guide groove;

[0011] Preferably, the rotating mechanism further comprises a transmission shaft, which is symmetrically arranged at both ends of the middle part of the water quality test pen, and the middle part of the two sliders close to the water quality test pen is provided with an axis groove movably connected to the transmission shaft;

[0012] Preferably, a spring is provided inside the side of the side shell close to the protective shell, and the other end of the spring is connected to the slider;

[0013] Preferably, jackets are symmetrically arranged on both sides of the inner wall of the protective shell, and the jackets are movably connected to the detection head;

[0014] Preferably, the jacket is made of silicone material.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. This portable PH-EC measuring instrument is used in conjunction with an outer shell, a protective shell, a water quality measuring pen and a detection head. The water quality measuring pen is pulled to the side away from the protective shell until the detection head at one end of the water quality measuring pen withdraws from the protective shell, and then rotated 180° so that the detection head faces the side away from the protective shell. Then, the water sample can be tested through the detection head at one end of the water quality measuring pen. After the test is completed, the detection head is flipped over and put into the protective shell. Compared with the protective cover that is available on the market, the protective shell of this device is fixedly connected to the outer shell and can be removed for use without causing loss.

[0017] 2. This portable PH-EC measuring instrument is used in conjunction with a side shell, a spring and a slider. The detection head withdraws from the protective shell and stretches the spring inside the side shell, and then controls the water quality measuring pen to rotate. At this time, the detection head faces the side away from the protective shell, and then the water quality measuring pen is released. At this time, the stretched spring will control the water quality measuring pen to retreat and reset, so that the end of the water quality measuring pen away from the detection head abuts against the side of the outer shell close to the protective shell, thereby achieving the purpose of easy use.

[0031] Working principle: When in use, pull the water quality testing pen 3 to the side away from the protective shell 2 until the detection head 4 at one end of the water quality testing pen 3 withdraws from the protective shell 2, and then rotate it 180° so that the detection head 4 faces the side away from the protective shell 2, and then the water sample can be tested through the detection head 4 at one end of the water quality testing pen 3. After the test is completed, the detection head 4 is turned over and put into the protective shell 2. When the water quality testing pen 3 is pulled to the side away from the protective shell 2, the detection head 4 withdraws from the protective shell 2 and stretches the spring 10 inside the side shell 5, and then the water quality testing pen 3 is controlled to rotate. At this time, the detection head 4 faces the side away from the protective shell 2, and then the water quality testing pen 3 is released. At this time, the stretched spring 10 will control the water quality testing pen 3 to retreat and reset, so that the end of the water quality testing pen 3 away from the detection head 4 abuts against the side of the outer shell 1 close to the protective shell 2.
