Abstract
The utility model relates to a dining demand display, which consists of a display device, a switch arranged on the display device, and a signal generating circuit arranged in the display device; wherein the signal generating circuit consists of a delay circuit and a signal generator, the switch is connected to an input control end of the delay circuit, and the signal generator is connected to the output end of the delay circuit. When the utility model is in operation, if a customer dining in a hotel or restaurant has to temporarily leave the table, a switch can be operated, a displaying light or sound as music form can tell that the customer still has dining demand, so the customer can continue dining without being affected; the appearance of the dining display can be a beer bottle shape or a beverage pop-can that can receive advertisement effects, and the inner cavity of the display can be stored with toothpick, napkin paper or flavoring, etc.
Description
Technical field
The utility model relates to the display that client has dinner and requires to waiter's reception and registration in a kind of catering trade.
Technical background
At present, in the hotel, the restaurant has dinner, client's dining table away from keyboard for a certain reason (such as going to toilet etc.) often appears, but find the phenomenon that the serviced member of the food of not eating up cleans up after returning, so just between client and waiter, dispute easily, cause all offending situation of both sides.
Summary of the invention
Technical problem to be solved in the utility model provides the display that a kind of client of expression has dinner and requires.
The technical scheme that the utility model adopted is: the utility model by display device, be arranged on the switch on the display device and the signal generating circuit that is arranged in the display device constitutes, signal generating circuit is made of delay circuit and signal generator, switch is connected the input control end of delay circuit, and signal generator is connected the output terminal of delay circuit.
The single-shot trigger circuit IC of the utility model delay circuit for constituting by time-base integrated circuit 555
1, switch meets IC
12 pin, resistance R, capacitor C meet IC respectively
17 pin and 6 pin, output terminal is 3 pin.
The utility model signal generator is made of light emitting diode, or by music integrated block IC
2, triode BG and loudspeaker constitute.
The utility model music integrated block IC
2Constitute IC by IC KD9300
1 Output terminal 3 pin meet IC
2Input end 2 pin, IC
2Output terminal 3 pin connect the base stage of triode BG, the collector of triode BG connects loudspeaker.
It is box-like that the utility model display device can be beer ampuliform, beverage cans shape or toothpick.
Good effect of the present utility model is as follows: apparent not device of the present utility model can be made into multiple shape, inside can be provided with cavity and be used to deposit toothpick, napkin paper, chopsticks, the assistant product of having a dinner such as flavouring, can improve catering trade service quality, it is identical or close with the outward appearance of propaganda material that the outward appearance of display device can be made into, for example make the beer bottle of certain brand, pop can, play the effect of advertising, client is in the hotel, when have dinner in the restaurant, as need leave in short-term the time, only need operating switch, the utility model can be by the form of the sounds such as display lamp or music, represent the information requirements of " customer need is left in short-term; be back soon, and please waiter not tidy up, and other clients do not seize the seat " to waiter or other clients, when seeing sound and light signal, waiter or other clients just understood client's requirement, have dinner conveniently for client provides, the utility model delay time sends to automatic stop signal, does not influence waiter's work.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model outside drawing;
Accompanying drawing 3 is the utility model circuit block diagram;
Accompanying drawing 4 is the utility model circuit theory diagrams.
Embodiment
Shown in accompanying drawing 1,2, display device 1 outward appearance of the present utility model is the beverage bottle of certain brand, in cavity 6 is arranged.
Shown in accompanying drawing 3,4, the utility model circuit comprises switch 4, by resistance R, capacitor C and IC
1The delay circuit 2 that (time-base integrated circuit 555) constitutes and by light emitting diode 5 or music integrated block IC
2The signal generator that (IC KD9300), triode BG and loudspeaker 3 constitutes constitutes, when signal generator is light emitting diode 5, client's manual manipulation switch 4 once, trigger pip enters IC
12 pin, make single-shot trigger circuit enter temporary stable state, 3 pin output high level, bright as the light emitting diode 5 of signal generator, equally when signal generator by music integrated block IC
2, when triode BG and loudspeaker 3 constitutes, manual manipulation switch 4 once, 3 pin high level enter music integrated block IC
2Triggering pin 2 pin, music integrated circuit IC
2Work, music signal amplifies through triode BG, sends melody by loudspeaker 3, and as shown in Figure 4, the utility model can adopt LED and music integrated circuit IC
2As signal generator, delay circuit 2 delay times arrive simultaneously, and circuit quits work, and delay time T is approximately 1.1RC, according to the delay time needs, can select the parameter of resistance R and capacitor C, and the optimum delay time is 2-5 minute.
Undoubtedly, the utility model not only is confined to above-mentioned embodiment, and display device and circuit part also have multiple remodeling and substitute.
