Abstract

The utility model relates to an automatic electric heating warming box, composed of a box body, a box cover, and an automatic control circuit, wherein, the structure of the box body and the box cover is completely the same as the prior art. The improvement of the utility model is that the combined part of the inner side of the box body and the box cover is provided with a plurality of supporting blocks, and the automatic control circuit is composed of a temperature control switch, a plurality of squeezing trigger switches and a heat generating pipe, wherein, the squeezing trigger switches are fixedly arranged on the supporting blocks arranged inside the box body, and the box cover is covered on the box body and the squeezing trigger switches. With the advantages of simple structure, reasonable design, easy fabrication, and convenient operation and use, the utility model which can automatically control the switching of a power supply and save electricity with high safety is an ideal product for placing the existing electric heaters in winter.

Description

A kind of automatic electric heating warming box

The utility model relates to a kind of heating system, and refering in particular to is a kind of automatic electric heating warming box.

In ice-cold winter, because the natural environment temperature is low, people's activity of being unwilling, thereby the rate of metabolism of human body slows down, make some centrifugal dirty positions far away on the human body, as hand, pin etc. feel cold, and in order to address this problem, people utilize warming oneself of coal fire, in recent years, occurred again utilizing electric energy to make quartz ampoule, the electric heating box that halide torch generates heat and warms oneself, the convenience though this method saves trouble is because the defective in its design, make its powered-down automatically, so not only wasted electric energy, and often therefore caused many unnecessary troubles even caused fire, brought inconvenience to people.

The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and reasonable in design, processing and manufacturing is easy, and is easy for operation, but the automatic electric heating warming box of automatic control power supply break-make.

The purpose of this utility model is achieved in that it is made up of casing, case lid, automatic control circuit, wherein the structure of casing, case lid and prior art are in full accord, its improvement is: at the position that box inside combines with case lid some back-up blocks are housed, automatic control circuit is made up of temperature control, some extruding trigger switches and heat-generating pipe, wherein, the extruding trigger switch is installed on the interior back-up block of casing, and the case lid lid is pressed on casing and the extruding trigger switch.

Below in conjunction with accompanying drawing the utility model is described in further details:

Accompanying drawing 1 is the utility model overall structure cutaway view.

Accompanying drawing 2 is the circuit diagram of automatic control circuit in the utility model.

See accompanying drawing 1,2, the utility model comprises casing 1, case lid 2, automatic control circuit 3, wherein the structure and the prior art of casing 1, case lid 2 are in full accord, its improvement is: with the position of case lid 2 combinations the consistent back-up block of level height 4 is housed in casing 1 inboard, automatic control circuit is by temperature detect switch (TDS) K _R, parallel extruding trigger switch group K ₁, K ₂, K ₃, K ₄R composes in series with heat-generating pipe, wherein, and parallel extruding trigger switch group K ₁, K ₂, K ₃, K ₄Be installed on the back-up block 4 in the casing, case lid 2 lids are pressed in casing 1 and extruding trigger switch K ₁, K ₂, K ₃, K ₄On.

Another embodiment of the present utility model is: the extruding trigger switch is installed in the bottom of casing 1.

Operation principle of the present utility model is summarized as follows: in advance with power connection of the present utility model, when needs use the time of the present utility model, only need hand or pin are placed on the case lid of heating case, utilize the gravity compressing case lid of hand or pin, simultaneously, extruding trigger switch on the case lid compressing case supports piece, owing to be parallel switches set, so as long as wherein any one switch pressurized is connected, will turn-on power, thereby the connection entire circuit makes the heat-generating pipe heating power, reaches the purpose of heating; When no longer needing to warm oneself, only need hand or pin are removed from case lid, because the strength of compressing on the extruding trigger switch disappears, switch automatically resets, thereby disconnects entire circuit, reaches the purpose of cutting off the electricity supply automatically.The utility model has saved the trouble that old-fashioned heating case is wanted Switching Power Supply owing to adopted said structure, cuts off the power supply automatically simultaneously, has eliminated the potential safety hazard of warming, and power saving, safety are a kind of splendid warming apparatus.

In sum, the utility model is simple in structure, and is reasonable in design, and processing and manufacturing is easy, easy for operation, but the automatic control power supply break-make, and power saving, safety are the desirable renewal products of existing electricity baking warmer in winter.

Claims

1, a kind of automatic electric heating warming box, comprise casing (1), case lid (2), automatic control circuit (3), wherein the structure and the prior art of casing (1), case lid (2) are in full accord, it is characterized in that: with the position of case lid (2) combination the consistent back-up block of level height (4) is housed in casing (1) inboard, automatic control circuit is by temperature detect switch (TDS) K _R, parallel extruding trigger switch group K ₁, K ₂, K ₃, K ₄R composes in series with heat-generating pipe, wherein, and parallel extruding trigger switch group K ₁, K ₂, K ₃, K ₄Be installed on the back-up block (4) in the casing, case lid (2) lid is pressed in casing (1) and extruding trigger switch K ₁, K ₂, K ₃, K ₄On.

2, a kind of automatic electric heating warming box according to claim 1, its feature also is: extruding trigger switch group also can be installed in the bottom of casing (1).
