Description

Scald -and coolling-prevention soupspoon

The utility model belongs to the electronics tableware, is applied to the infant and has meal.

Present soupspoon in use exists two problems; 1. cross because of food through regular meeting with soupspoon hello infant and scalded the cool infant's dining that influences, form human oral examination temperature and do not meet hygienic requirements again; 2. do not focus one's attention on when the child is often because of dining fond of play, influence child's appetite and health digesting and assimilating food.

The purpose of this utility model is in order to solve above problem, provide a kind of can prevent to have meal the time food cross and scald or cool excessively, meet hygienic requirements, can resemble again and attract the focus one's attention on anti-scald anti-cool soupspoon of dining of child the toys game.

For reaching above purpose, feature of the present utility model is that soupspoon shank shape is a flat garden tubular, the inner series loop that is made of two energy alternations temperature-sensing element, constant temperature fine setting, light-emitting component, minicell and button switch.The utility model housing main body is to roll into bronze flake or latten(-tin), also can be latter half of with nonmetal flat garden tubulars of making such as bakelite, plastics at handle.The employed temperature-sensing element of the utility model is a bimetal leaf, particularly with being subjected to the bigger thin bimetal leaf of thermal change ideal.The constant temperature fine setting of indication is the screw that an adjustable height is installed on the brass contact chip.Light-emitting component is to adopt red light emitting diodes and green LED, and wherein small-sized redness in Japanese Guia Hill and the green LED with import is best.Minicell is to adopt the coin shape battery.Switch is a button switch, be with elasticity preferably latten(-tin) as switch contact.The utility model operation principle (as shown in Figure 3) is that the series loop by two energy alternations realizes; First loop: the negative pole of minicell connects the soupspoon metal-back, and the soupspoon metal-back is connecting bimetal leaf.The positive pole of minicell then connects the positive pole of red light emitting diodes on the other hand, contact chip under the brass of the negative pole connection constant temperature fine setting of red light emitting diodes.(above 45 ℃) heat is to pass to bimetal leaf by the soupspoon front portion when scalding when food is crossed, and makes contact chip under the bimetal leaf heated bending contact brass, connects red light emitting diodes, minicell, and formation work loop makes red light emitting diodes luminous.Second loop: the minicell negative pole connects the soupspoon metal-back, and the soupspoon metal-back is connecting bimetal leaf.The positive pole of minicell then connects an end of button switch on the other hand, and the switch other end connects the positive pole of green LED.The negative pole of green LED is connected on the brass of constant temperature fine setting on the contact chip.Promptly supress button switch when picking up soupspoon.If food is crossed cold or child back (near 30 ℃ of normal temperature) bimetal leaf reinstatements of suffering from cold of eating, break away from contact chip under the brass, contact chip on the contact brass, connection green LED and minicell form new electric loop, make green LED luminous.Draw child's interest thereby swash, promote appetite.When soupspoon need not put down, button switch two contact point bullets from, the green glow circuit promptly quits work.

The utility model is compared with present soupspoon has automatic warning, sends green glow again automatically after anti-scald anti-cold, child eat, and has the character as the recreation, the usefulness of special suitable for baby dining.

Fig. 1 is the vertical view of anti-scald anti-cool soupspoon in the Figure of description; Fig. 2 is the full sectional view of anti-scald anti-cool soupspoon; Fig. 3 is the circuit diagram of this soupspoon; (1) is the lucite of soupspoon lightening hole in Fig. 1, Fig. 2; (2) be the button switch of soupspoon shank; (3) be minicell; (4) be contact chip on the brass (green glow circuit); (5) be ambroin; (6) be the temperature-sensing element bimetal leaf; (7) be contact chip under the brass (ruddiness circuit); (8) be the constant temperature fine adjustment screw; (9) be fixed screw; (10) be red light emitting diodes; (11) be green LED; (12) be epoxy insulating board; (13) press sheet for GND; (14) be plastics tail bonnet.

Embodiment:

The soupspoon shell adopts the 0.7mm bronze flake; Bimetal leaf is iron and the dilval bimetal leaf that adopts in the fluorescent lamp starter; Light-emitting component adopts the small-sized redness in Japanese Guia Hill, green LED; Minicell adopts the AG10 type; Button switch is made up of the little garden of moving plate, stator and plastics post.Moving plate is to be made by the latten(-tin) of 0.3mm, and stator is made the L type with the latten(-tin) of 0.3mm; The constant temperature fine setting is made up of the latten(-tin) of two 0.3mm and the small-sized screw of an adjustable height.Two contact chips 2mm of being separated by fixes with plastic heat sealing; The positive and negative sheet that presses of battery is to adopt resilient latten(-tin) to make; Circuit board is made with epoxy insulating board.

During making, earlier copper sheet is cut into shape, strikes out half garden shape then as Fig. 1.Again bimetal leaf (6) point is welded in bottom behind the soupspoon, GND presses sheet (13) point and is welded in rear portion in the handle, at this moment could handle rolls up be pressed into flat garden tubular.Other constant temperature fine setting, light emitting diode, button switch, anode press sheet and are fixed on the epoxy insulating board with the Xiao Liu nail respectively, form green glow loop, ruddiness loop (as Fig. 3) in series respectively and can alternately carry out work.For the sensitivity that improves temperature-sensing element and specious, machine glass tegillum is housed on the lightening hole, afterbody is sealed with vinyl cover, and handle outer casing bottom seam is close with soldering.During debugging, as long as take out insulating circuit board in the handle, the height of adjusting the height of constant temperature fine setting primary screw gently or adjusting contact chip on the brass makes it be fit to needed temperature range side can.So just made anti-scald anti-cool soupspoon.
