Abstract

The utility model discloses an electronic water boiling alarm which is an alarm device matched with a household digester for use and automatically alarms when water boils. A housing of the alarm is horn-shaped and faces upwards; threads are formed at the neck of a housing of a sensor; the sensor penetrates through a circular hole in the center of a pot cover; the sensor and the housing (15) are screwed down by a sealing ring, a base pad and a nut (18), so that the pot cover (17) is connected with the housing (15) into a whole; the upper end of an outer spring (3) is propped against the lower bottom surface of a slip ring (7), and squeezes a guide sleeve (5), an anode bottom plate (8), a buzzer (9) and a pressing sleeve (10) through the slip ring (7) tightly; the upper end of the pressing sleeve (10) is fixed on a grate cage (11) by a screw (12); the grate cage (11) and the housing (15) are pressed tightly and are connected into a whole by a screw cover (14); a button switch (13) is fixed on the grate cage (11); the upper end of an inner spring (4) is propped against the lower bottom surfaces of two button batteries (6); two contacts of the button switch (13) are connected with the slip ring (7) and the anode bottom plate (8) by wires respectively; and the slip ring (7) is separated and insulated from the anode bottom plate (8) by the nonmetallic guide sleeve (5). The alarm is integrated with a top cover of the household digester, and does not occupy an additional space any longer, and the housing of the alarm is designed into the horn shape and faces upward, so that sound can be amplified, and sound resonance can be created in a whole indoor space.

Description

Electronics boiling water alarm

Technical field

The utility model belongs to the household supplies field, is applicable to the kitchen cooking utensil---various steamers, pot for cooking rice, slaughterhouse, frying pan and various kettle.

Background technology

Phenomenons such as at present, the pot class vessel on the market are comparatively original, and pot is done, pot overflows happen occasionally.Though the part kettle is provided with the steam whistle, because this device has certain requirement to steam pressure, it is unreliable in most cases to work.Though some people has bought this type of kettle, is still ruined by baked.

The electronics boiling water alarm of up-to-date listing, though can report to the police when water is opened, it need occupy exceptional space, and is unrelated with the cooking utensil that family uses.And, can only be used for kettle.

Summary of the invention

The purpose of this utility model is that the lid of cooking utensil that alarm and family are used is integrated.

The technical solution of the utility model is: shell of the present utility model is tubaeform, be directed upwardly, the sensor outer housing neck has screw thread, is passed by the circular hole at pot cover center, and tighten by sealing ring, base wad, nut and shell, pot cover and shell are connected as a single entity, and the upper end of outer spring holds out against on the bottom surface of slip ring, and by slip ring with guide pin bushing, anodal base plate, buzzer and gland jam-packed, the upper end of gland is screwed on the comb cage, and by spiral cover comb cage and shell is compressed and to be connected as a single entity; Fixing button switch on the comb cage simultaneously, the upper end of inner spring withstands on the bottom surface of two button cells, and two contacts of button switch link to each other with slip ring, anodal base plate respectively by lead; Between slip ring and the anodal base plate, then separate insulation by nonmetallic guide pin bushing.

The beneficial effects of the utility model: the utility model is structure as a whole the upper cover design of electronic alarm device and kettle, during work, button switch by the next top is connected power supply, at this moment, because of not action of the bimetal leaf in the bottom sensor, circuit is not switched on fully, so buzzer sounding not.When water was opened, a large amount of steam were sharply evaporated by liquid level, rapidly the heating kettle tops.Bimetal leaf in the sensor moves because being heated, and connects circuit, and the buzzer energising gives the alarm.During end, press top switch again, cut off the electricity supply, buzzer stops.Result of use and surface structure all are better than existing product.

Description of drawings

Accompanying drawing 1 is the utility model overall structure schematic diagram.

The specific embodiment

Of the present utility model shown in attached 1 figure, by shell, sensor, button cell, buzzer, button switch, etc. 18 kinds of parts form.

Sensor 1 shell neck has screw thread, is passed by the circular hole at pot cover 17 centers, and tightens with shell 15 by sealing ring 2, base wad 16, nut 18, and pot cover 17 and shell 15 are connected as a single entity, and nut 18 is integrated with shell 15 edges;

Bimetal leaf is equipped with in sensor 1 inside.The two poles of the earth of bimetal leaf, the shell by sensor 1 and sealing and nut 18 is connected with inner spring 4 with outer spring 3 respectively.

The upper end of outer spring 3 holds out against on the bottom surface of slip ring 7, and passes through slip ring 7 with guide pin bushing 5, anodal base plate 8, buzzer 9 and gland 10 jam-packeds.

The upper end of gland 10 is fixed on the comb cage 11 with screw 12, and by spiral cover 14 comb cage 11 and shell 15 is compressed, is connected as a single entity.Fixing button switch 13 on the comb cage 11 simultaneously.

The upper end of inner spring 4 withstands on the bottom surface of two button cells 6 (negative pole), and button cell 6, anodal base plate 8 are compressed with the bottom surface of buzzer 9.

Two contacts of button switch 13 link to each other with slip ring 7, anodal base plate 8 respectively by lead; And between slip ring 7 and the anodal base plate 8, then separate insulation by nonmetallic guide pin bushing 5.

During work, by the self-locking of the button switch 13(of next top band), connect power supply.At this moment, because of not action of the bimetal leaf in the bottom sensor 1, circuit is not switched on fully; So buzzer is sounding not.

When water was opened, a large amount of steam were sharply evaporated by liquid level, heated pot cover 17 tops rapidly.Bimetal leaf in the sensor 1 moves because being heated, and connects circuit.Buzzer 9 energisings give the alarm.

During end, press top switch 13 again, cut off the electricity supply; Buzzer 9 stops.

All outsourcing pieces among the design all have supply on the market.
