Abstract

The utility model belongs to a rotary plate on the dining table. The provided intelligent dinging table rotary plate comprises a base (4), an upper cover (7), a control circuit (2) and a motor (M). The base (4) is provided with a rotary ring gear (6) and a motor. The upper cover (7) is provided on the ring gear (6). A circle of magnets (1) are provided with intervals at the lower part of the upper cover (7). Two magnetic detectors (3) which are put in order parallely and supply signals for the control circuit (2) are arranged on the base (4). The utility model can control the starting and stopping through rotating the plate face thereof. Therefore, the utility model which is convenient to use saving special switches to control, switches and lead wires can make the table face more tidy and nicer, reduce the fault rate of the rotary plate and prolong the working life of the rotary plate.

Description

The intelligence Lazy Susan

Affiliated technical field

The utility model belongs to a kind of Lazy Susan, mainly proposes a kind of intelligent Lazy Susan.

Background technology

Existing electric turn table all has a gauge tap, when the guest has a dinner, needs waiter open switch, and rotating disk just rotates always, but the startup of the uncontrollable rotating disk of guest and stopping to be used inconvenient.Because rotating disk rotates at mealtime always, battery life and mechanical life all are affected, and the switch lead-out wire influences the dining table overall appearance simultaneously.

Summary of the invention

The purpose of this utility model promptly be propose a kind of easy to use, can control the intelligent Lazy Susan that rotating disk is recklessly acted and stopped by deck plate.

The purpose of this utility model can be realized by following technical scheme: described Lazy Susan has a base, loam cake, base is provided with gear ring, motor and control circuit, loam cake is positioned at above the gear ring, rotate by the driven by motor gear ring, in the loam cake bottom one all magnet is set, the magnetic detector that two parallel arranged are used for providing signal to control circuit is set on the base.

Described magnetic detector is two tongue tubes or two Hall elements.

As seen from the above, the utility model can rotate by the table top on it and control start and stop, and is easy to use, do not need special switch control, saved switch and lead-in wire, make desktop more neat and artistic, reduce the fault rate of rotating disk, prolonged the service life of rotating disk.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is the vertical view of Fig. 1.

Accompanying drawing 3 is a control circuit schematic diagram of the present utility model.

Among the figure, 1, magnet, 2, control circuit, 3, magnetic detector, 4, base, 5, reduction box, 6, gear ring, 7, loam cake, 8, battery.

The specific embodiment

In conjunction with the accompanying drawings, describe the specific embodiment of the present utility model in detail:

Shown in accompanying drawing 1,2, the utility model mainly comprises base 4, loam cake 7, gear ring 6, motor, battery 8 are set on base, loam cake is positioned at above the gear ring 6, one all magnet 1 is set at interval in loam cake 7 bottoms, be provided with and magnet 1 corresponding magnetic detector 3 on the base 4, it can be made of two tongue tubes or two Hall elements.The signal of magnetic detector 3 offers control circuit 2, and the control motor rotates, and rotates thereby motor drives gear ring 6 drive loam cakes 7 by reduction box 5, drives Dining table top by loam cake 7 and rotates.

Circuit working principle as shown in Figure 3 is: control circuit is mainly by single-chip microcomputer IC ₁Control, tongue tube S ₁, S ₂Whether be used for detecting rotating disk as magnetic detector rotates and rotation direction; Triode T ₁, T ₂And P _1.0Deng composition electrification reset control circuit, purpose is the low consumption that reduces when not working; Triode T ₃-T ₆Be electrode drive circuit, concrete working method is as follows:

1, battery saving mode:

(1), electrification reset: stir rotating disk and often open tongue tube S ₁, S ₂In have one when closed, through diode D ₁, D ₂Give C ₁Charging, triode T ₁, T ₂Conducting, single-chip microcomputer IC ₁Electrification reset; Back P resets _1.0Put 1, IC ₁Enter duty;

(2), close power down: when rotating disk need cut out, pass through P _1.1, P _1.2Detect clarinet S ₁, S ₂Whether disconnect, when whole disconnection, P _1.0Put 0, make IC simultaneously ₁Enter power-down mode, finish the work of closing.

2, control model (program): main program is by P _1.1, P _1.2Detect S ₁, S ₂On off state is when the magnet order is passed through S ₁, S ₂Detect its direction of motion during detection, P _1.3, P _1.4Be used for controlling direction of motor rotation.

(1), when stirring rotating disk with hand, IC ₁Power on, detect rotation direction simultaneously, control output makes the rotation of motor M by stirring direction, finishes to stir rotating disk and start function.Timing routine work when reaching setting-up time (5-10 minute), enters the power down program of closing simultaneously.

(2), during the rotating disk normal rotation, all magnet 1 on the loam cake 7 contacts tongue tube S at set intervals ₁, S ₂, buttress rotating disk if any the people, in official hour, detect less than tongue tube S ₁, S ₂During variation, enter and close the power down program, finish hold function behind the hand steered rotating disk certain hour.

(3), during the rotating disk normal rotation, stir rotating disk round about if any the people, tongue tube S ₁, S ₂Detect magnet 1 rotation direction and become anti-, promptly enter immediately and close the power down program, finish backwash and promptly stop function.

Described control circuit all is made of cmos device, can use Single-chip Controlling, and also utilogic circuit static power can be ignored (less than 10 μ A), need not establish power switch.

Claims

1, a kind of intelligent Lazy Susan, have base (4), loam cake (7), control circuit (2), motor (M), base (4) is provided with and rotates gear ring (6), motor, loam cake (7) is arranged on the gear ring (6), it is characterized in that: loam cake (7) bottom fixed interval one all magnet (1) is provided with the magnetic detector (3) that two parallel arranged are used for providing signal to control circuit (2) on the base (4).
