Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clear, complete description, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all Embodiment, be based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, shall fall within the protection scope of the present invention.

It is to be appreciated that if directionality involved in the utility model example indicates（Such as up, down, left, right, before and after, it is interior, Outside ...）, then directionality instruction be only used for explain in a certain particular pose（As shown in the picture）Under it is opposite between each component Position relationship, motion conditions etc., if the particular pose changes, directionality instruction also correspondingly changes therewith.

In the present embodiment, as shown in Figure 1, TDS detection pens include shell 1, pcb board 2, battery tray 3, wherein in shell 1 Portion is hollow, and pcb board 2 is arranged in the inside of shell 1；Pcb board 2 be equipped with probe 4, function button 5, metal clips 6, LED screen 7 with Control chip.

Pcb board 2 is front end in the test side for detecting pen close to TDS, and opposite side is rear end.

Probe 4 is arranged in the front end of pcb board 2, and is pierced by shell 1；Metal clips 6 is arranged in the rear end of pcb board, and wears 3 bottom of battery tray is crossed, to connect battery；Probe 4, function button 5, metal clips 6, LED screen 7 are electrically connected with pcb board 2 respectively, Pcb board is electrically connected with control chip.

It is opened with viewing area the display area that shell 1 is provided with viewing area 9, LED of opening screens 7 in position corresponding with LED screen 7 Mouth 9 overlaps, and shell 1 posts glass lens 8, transmission region and the viewing area opening 9 of glass lens 8 in 9 outside of viewing area opening It overlaps, so that the display content of LED screen 7 can clearly be seen through glass lens 8 and viewing area opening 9, and glass lens 8 There can be preferable protective effect to LED screen 7, prevent extraneous dust from entering, be also prevented from LED screen 7 and scratched by foreign matter.

Shell 1 is provided with key opening 11 in position corresponding with function button 5, and keycap 10 passes through key opening 10 and function 5 fastenings of button/fitting, so that function button 5 more convenient can operate.

Shell 1 extends at front end, forms the probe encirclement 12 of protection probe 4, and 12 inside of probe encirclement is hollow lead to Road and in being enclosed in the probe 4, and the length of of length no more than probe encirclement 12 that probe 4 is stretched out, to prevent probe 4 Bending or impaired under the effect of external force；Probe encirclement 12 is surrounded by strip-shaped hole 13, is conveniently discharged when detecting water body The air of 12 inner cavity of probe encirclement, so that water body can come into full contact with probe 4.

As shown in Fig. 2, TDS detection pens further include pen cap 14 and battery cap 15, pen cap 14 connects respectively with battery cap 15 It is connected on the front and rear end of shell 1, pen cap 14 can be detected in TDS prevents probe 4 contaminated when pen need not use, can also Get up to probe 4 effect of protection, and battery cap 15 can have metal clips 6 pressuring action, ensure metal clips 6 and electricity Battery in stall 3 can come into full contact with, so that well conducting, while can also protect battery that can stablize and be fixed on battery In seat 3, prevent battery from deviating from.

Preferably, pen cap 14 and battery cap 15 use click on fashion to form immovable fitting with shell 1 respectively, also may be used certainly Using other forms, such as screw-thread fit, does not tire out one by one state herein.

Since the utility model is only there are one function button 5, control chip can within set corresponding program with response function The different operation mode of button 5, following instance only enumerate one of which control mode, but do not represent consistent with the control mode All control modes, other similar control modes are also just within the protection domain of the application.

Embodiment one：Function button 5, which can have, to be clicked and double-clicks kind of a control mode, wherein clicking function button 5 can be with Electric power starting and the closing for controlling TDS detection pens, can be by clicking function button 5 in the state that TDS detection pens are closed By power supply opening, at this time into the water by the front end of TDS detections, so that water body is come into full contact with probe 4 can be detected, LED screen 7 can show detection as a result, when needing 7 continuously display current detection result of LED screen, it is only necessary to double-click function Testing result can be locked in LED screen 7 by button 5, and testing result is watched after facilitating the probe 4 of TDS detection pens to leave water body, Double-click function button 5 can be purged the content of LED screen 7 again, and function button 5 can be clicked after use and closes power supply, Certain TDS detections pen also can voluntarily close power supply when not receiving operation signal in two minutes, to save electricity.

A function button is only arranged by being detected in TDS in the utility model on pen, by different modes of operation come real Now corresponding function can avoid the problem that user is easy to happen when in face of more button and obscure well, Ke Yifei It is often easily operated and is used, greatly improve the working efficiency of user, also can avoid unnecessary maloperation hair It is raw.

The preferred embodiment of the utility model, still, the utility model and unlimited are described in detail above in association with attached drawing Detail in the above embodiment can be to the skill of the utility model in the range of the technology design of the utility model Art scheme carries out a variety of simple variants, these simple variants belong to the scope of protection of the utility model.

It is further to note that specific technical features described in the above specific embodiments, in not lance In the case of shield, it can be combined by any appropriate mode, in order to avoid unnecessary repetition, the utility model is to each The possible combination of kind no longer separately illustrates.

In addition, arbitrary combination can also be carried out between a variety of different embodiments of the utility model, as long as it is not disobeyed The thought for carrying on the back the utility model, equally should be considered as content disclosed in the utility model.
