Abstract

The utility model provides a PH test pen especially relates to PH test equipment field, this device is through increasing the direct dress liquid box on the nib of peripheral hardware at PH test pen to for dress liquid box provides the gasbag that absorbs the liquid that awaits measuring, through straw and tubule, conveniently press the gasbag with holding between the fingers with the hand, can extract the liquid that awaits measuring and get into dress liquid box, the nib can accomplish the PH with the liquid contact that awaits measuring in the dress liquid box and detect, this equipment structure is simple, but the operator one-hand operation, it is all very convenient, swift to take the liquid that awaits measuring and measure and read measured data.

Description

PH test pen

Technical Field

The utility model relates to a PH test equipment field especially relates to a PH test pen.

Background

The PH test pen is a special device for measuring the PH value of liquid, is a portable and high-precision test instrument, and adopts a common measurement mode that a measuring cup takes a proper amount of liquid to be measured, and a pen point of the PH test pen extends into the measuring cup for testing.

Still must have clean graduated flask to carry out supplementary experiment in present PH test pen use, only directly stretch into liquid under the condition of not having the graduated flask and measure, very inconvenient, consequently need improve the PH test pen, make it take out the use alone to convenient and fast.

SUMMERY OF THE UTILITY MODEL

To the not enough that exists among the prior art, the utility model provides a PH test pen makes the measurement process of PH test pen convenient and fast more.

According to the utility model discloses an embodiment, a PH test pen, including the test pen body, the test pen body serves and is equipped with the nib, test pen body one end has set firmly the dress liquid box, the nib is located inside the dress liquid box, dress liquid box bottom is equipped with the tubule, dress liquid box lateral wall intercommunication has the straw, the test pen side has set firmly the gasbag, the gasbag with the straw intercommunication.

Contrast prior art, the utility model discloses following beneficial effect has:

this device is through increasing the direct dress liquid box on the nib of peripheral hardware at the PH test pen to for dress liquid box provides the gasbag that absorbs the liquid that awaits measuring, through straw and tubule, conveniently pinch the gasbag with the hand, can extract the liquid that awaits measuring and get into dress liquid box, the nib can accomplish the PH and detect with the liquid contact that awaits measuring in the dress liquid box, this equipment simple structure, but the operator one-hand operation takes the liquid that awaits measuring and reads measured data and all very convenient, swift.

Further, still include the visor, the visor is used for covering the tubule head.

Furthermore, the liquid containing box is made of transparent glass, and scale marks are arranged on the side wall of the liquid containing box.

Drawings

Fig. 1 is a structural diagram of a PH test pen according to a first embodiment of the present invention;

in the above drawings: 1. a test pen body; 2. a pen point; 3. a liquid containing box; 31. a thin tube; 4. a straw; 5. an air bag, 6 and a protective cover; 7. scale lines; 8. a test button; 9. a display screen.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

The embodiment of the utility model provides a PH test pen, as shown in figure 1, including test pen body 1, be equipped with nib 2 on one end of test pen body 1, test button 8 and display screen 9 all set up on test pen body 1, liquid containing box 3 has been set firmly to one end of test pen body 1, nib 2 is located inside liquid containing box 3, and liquid containing box 3 detachably installs in one end of test pen, the later stage of being convenient for is dismantled and is washd; a thin tube 31 is arranged at the bottom of the liquid containing box 3, the thin tube 31 is communicated with the liquid containing box 3 into a whole, the thin tube 31 is a needle-shaped thin tube 31 with the length of about 2cm and the inner diameter of about 1mm, so that liquid to be detected cannot flow out of the thin tube 31 due to gravity, the side wall of the liquid containing box 3 is communicated with a suction tube 4, the suction tube 4 is a rubber pipeline with the inner diameter of about 2mm, an air bag 5 is fixedly arranged on the side surface of the test pen, and the air bag 5 is communicated with the suction tube 4; this device is through increasing the direct dress liquid box 3 on nib 2 of peripheral hardware at the PH test pen to for dress liquid box 3 provides the gasbag 5 that absorbs the liquid that awaits measuring, through straw 4 and tubule 31, conveniently pinch pressure gasbag 5 with the hand, can extract the liquid that awaits measuring and get into dress liquid box 3, nib 2 and the liquid contact that awaits measuring can accomplish the PH and detect in dress liquid box 3, this equipment structure is simple, but the operator one-hand operation, it is all very convenient, swift to take the liquid that awaits measuring and measure and read measured data.

In a further scheme, as shown in fig. 1, the protective cover 6 is further included, the protective cover 6 is used for covering the head of the thin tube 31, the protective cover 6 is a plastic protective cover 6, and the purpose of the arrangement is to protect the thin tube 31 from being damaged by collision.

In a further scheme, as shown in fig. 1, the liquid containing box 3 is made of transparent glass, scale marks 7 are arranged on the side wall of the liquid containing box 3, the liquid containing box 3 made of glass can be convenient for operators to observe the liquid to be measured, and the scale marks 7 can also provide more reference parameters for experimental data and facilitate the operators to collect the liquid to be measured with correct measurement.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
