Above-mentioned leg comprises arrangement for adjusting height.

Compared with prior art, the utlity model has following outstanding beneficial effect:

1,, in patient's discharge opening when liquid, movement range is little, easy to use;

2, pond can be automatically moved in face of patient, easy to use;

3, without manual intervention, time saving and energy saving;

4, can reduce the fatigue of doctor's arm;

5, can improve doctor's performance accuracy;

6, Height Adjustable, can adapt to different dental treatment chairs;

Fig. 2 is top view of the present utility model.

Fig. 3 is circuit diagram of the present utility model.

Detailed description of the invention

Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.

As shown in Figure 1, 2, this utility model comprises pond 3, electric bell 2, support section, motion parts and control section.Described electric bell 2 is fixed on support section.

Described support section comprises guide rail 8 and leg 7, and described pond 3 is positioned on guide rail 8, can horizontally slip along guide rail 8.Described motion parts comprises motor 6, sprocket wheel 1 and chain 4, and described sprocket wheel 1 quantity is two, lays respectively at two ends, and described chain 4 is on sprocket wheel 1, and described motor 6 output shafts are connected with one of them sprocket wheel 1.Described chain 4 is connected with the bottom in pond 3.When after actuating motor 6, sprocket wheel 1 is setting in motion under the drive of motor 6, horizontally slips along guide rail 8 at the drive sink 3 of chain 4.

When use, this utility model is placed on to the side for the treatment of operations chair, makes to treat guide rail 8 and be placed in the top for the treatment of operations chair away from motor terminal.Doctor can be placed on ancon on guide rail 8 fatigue to reduce arm in therapeutic process, improves performance accuracy simultaneously.

Described control section comprises travel switch 5 and button.Described travel switch 5 quantity are two, are separately fixed at the two ends of support section, can encounter travel switch 5 when pond 3 slides into any one end.Described button is arranged on treatment chair headrest place.After patient lies down, head is pressed on headrest and button can be pressed.

Described control section also comprises positive contactor KM1, reversion catalyst KM2, and its circuit diagram as shown in Figure 3, represents with SQ1 away from motor terminal travel switch in Fig. 3, represents with SQ2 near motor terminal travel switch, and electric bell 2 use SJ represent.

Described motor 6 connects respectively the contact lead-out terminal of positive contactor KM1 and reversion catalyst KM2 by wire, positive contactor KM1 is connected power supply with the contact input terminal of reversion catalyst KM2, wherein by positive contactor KM1, motor 6 is connected with power supply forward, by reversion catalyst, KM2 makes motor 6 be connected with reversal of power.Described control circuit comprises the time control circuit being in parallel, reverse turn control circuit, forward control circuit and bell circuit, described time control circuit comprises the button normally-closed contact SB1-1 and the time relay coil KT1 that are linked in sequence, described reverse turn control circuit comprises the button normally opened contact SB1-2 being linked in sequence, near motor terminal travel switch normally-closed contact SQ2 and reversion catalyst KM2 coil, described forward control circuit comprises the time relay timing closing contact KT1-1 being linked in sequence, away from motor terminal travel switch normally-closed contact SQ1 and positive contactor KM1 coil, described bell circuit comprises the time relay moving together contact KT1-2 being linked in sequence, time relay time delay break contact KT1-3 and electric bell SJ.

The operation principle of control section is, in the time that patient lies down, button is pressed, button normally-closed contact SB1-1 disconnects, time control circuit no power, time relay timing closing contact KT1-1 disconnects, forward control circuit no power, button normally opened contact SB1-2 closure, if pond 3 is positioned at the close motor terminal of guide rail 8, pond 3 will be rushed open near motor terminal travel switch, its contact SQ2 disconnects, road no power is controlled in reversion, if pond 3 is not in close motor terminal, contact SQ2 closure, reverse turn control circuit energising, reversion catalyst KM2 coil electricity, reversion catalyst KM2 contact obtains electric adhesive, motor 6 is connected with reversal of power, motor 6 reverses, drive leading screw 2 to rotate, drive pond 3 to moving near motor terminal by leading screw 2, until encounter near motor terminal travel switch, disconnect near motor terminal travel switch normally-closed contact SQ2, reverse turn control circuit disconnects, motor 6 shuts down.When in client need discharge opening when liquid, first lift head, button discharges, its normally opened contact SB1-2 disconnects, reverse turn control circuit disconnects, normally-closed contact SB1-1 closure, time control circuit energising, time relay coil KT1 obtains electric, moving together contact KT1-2 adhesive, bell circuit energising, electric bell obtains the electric sound that sends, doctor lifts arm after hearing sound, prevent that arm from being bumped against by pond 3, after the time t setting, time delay break contact KT1-3 disconnects, bell circuit power-off, electric bell quits work, timing closing contact KT1-1 closure simultaneously, the energising of forward control circuit, positive contactor KM1 contact adhesive, motor 6 is connected with power supply forward, motor 6 forwards, drive pond 3 to moving away from motor terminal by leading screw 2, in the time that pond 3 is encountered away from motor terminal travel switch, its contact SQ1 disconnects, forward control circuit disconnects, motor 6 shuts down.Now pond 3 is positioned at before patient's body, and patient only need bow one's head and liquid in mouth can be told in intake pool 3, after patient again lie down, pillow knob down is pressed, reverse turn control circuit energising, and motor 6 reverses, pond 3 moves near motor terminal, and doctor can continue to treat.After treatment finishes, turn off power supply, remove water-pool rack.

Leg 7 described in prioritization scheme comprises arrangement for adjusting height, scalable whole height, thus can better be applicable to different treatment operations chairs.

It should be noted that; particular of the present utility model have been described in detail this utility model; for a person skilled in the art, the various apparent change of in the situation that not deviating from spirit and scope of the present utility model, it being carried out is all within protection domain of the present utility model.
