Description

Novel structure of hand warmer

Technical Field

The utility model relates to a novel structure of hand warmer.

Background

The traditional electric hot-water bag is in the heating process because the one-time fusing pipe is disconnected due to overheating, so that the electric hot-water bag cannot be reheated, the generation of after-sale is caused, even the direct scrapping and replacement are caused, and the waste of resources is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the weak point in the prior art, provide a novel structure of hand warmer, adopt heating member and manual reset thermal circuit breaker to concatenate, can prevent that the heating member from overheated, simultaneously cooling down can make electrically controlled device and heating member resume work through manual reset after the heating member is overheated, reduced the production after sale to the cost is reduced, economic benefits is improved, has reduced and has scrapped, has reduced the waste of resource.

In order to achieve the above purpose, the utility model adopts the following scheme:

the utility model provides a novel structure of hand warmer, including the casing that has installation space, set up in heating member, heat-retaining medium in installation space and with heating member electric connection's electrically controlled device, the last non-self-resetting thermal circuit breaker that is provided with the heating member concatenates together.

In one or more embodiments, the non-self-resetting thermal circuit breaker is a voltage-holding thermal protector or a manual reset fuse breaker with a manual reset button or a PTC thermistor.

In one or more embodiments, the heat storage medium is a liquid medium, the heating body heats the liquid medium, and the shell absorbs heat transferred by the liquid medium and releases the heat to the outside.

In one or more embodiments, the heat storage medium is a non-liquid non-conductive medium, the heating body heats the non-liquid non-conductive medium, and the shell absorbs heat transferred by the non-liquid non-conductive medium and releases the heat outwards.

In one or more embodiments, when the heat storage medium is a liquid medium, the shell is a flexible or hard shell, and when the heat storage medium is a non-liquid non-conductive medium, the shell is a hard or flexible shell.

Has the advantages that: the utility model provides a novel structure of hand warmer adopts heating member and manual reset thermal circuit breaker to concatenate, can prevent that the heating member is overheated, and the cooling can make electrically controlled device and heating member resume work through manual reset after the heating member is overheated simultaneously, has reduced the production after sale to the cost is reduced improves economic benefits, has reduced and has scrapped, has reduced the waste of resource.

Detailed Description

The application scheme is further described below with reference to the accompanying drawings:

example (b):

referring to fig. 1, 2 and 5, the present embodiment provides a novel structure of a hand warmer, including a housing 1 having an installation space, a heating body 2 disposed in the installation space, a heat storage medium 4, and an electric control device 3 electrically connected to the heating body 2, a non-self-resetting thermal circuit breaker 31 connected in series with the heating body 2 is disposed on the electric control device 3, an input end of the non-self-resetting thermal circuit breaker 31 is connected to a power supply, and an output end of the non-self-resetting thermal circuit breaker 31 is connected to the heating body 2.

Further, the non-self-resetting thermal breaker 31 is a voltage-holding type thermal protector or a manual reset fuse breaker with a manual reset button or a PTC thermistor.

Preferably, the voltage holding type thermal protector is a PTC thermal protector.

In the use of the user, if the temperature of the hand warmer is too high, the non-self-reset thermal circuit breaker can break the circuit by the circuit 31, if the temperature of the hand warmer drops, the non-self-reset thermal circuit breaker 31 cannot automatically connect the circuit, and the user needs to manually press a reset button or pull out a power supply to reset the hand warmer after newly plugging in the power supply, so that the hand warmer continues to work.

Further, the heat storage medium 4 is a liquid medium, the heating body 2 heats the liquid medium 4, and the shell 1 absorbs heat transferred by the liquid medium and releases the heat to the outside.

Further, when the heat storage medium 4 is a liquid medium, the shell 1 is a flexible or hard shell.

Preferably, the heat storage medium 4 is water or heat storage oil, the heating body 2 heats the liquid medium 4, and the shell 1 absorbs the heat transferred by the liquid medium and releases the heat outwards.

Example two:

referring to fig. 3 and 4, the only difference between this embodiment and the first embodiment is that when the heat storage medium 4 is a non-liquid non-conductive medium, the housing 1 is a hard housing or a flexible housing, the heat storage medium 4 is ceramic, a thermal insulation material 5 is further disposed in the housing 1, the heating body 2 heats the ceramic, and the ceramic heats and transmits heat to the housing 1 through the thermal insulation material 5.

Further, the non-self-resetting thermal breaker 31 is connected in series with the temperature controller 32. The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
