The utility model relates to a rechargeable hand warmer, which comprises an outer thermal insulation layer and an inner thermal insulation layer, an electric heating wire is installed between the outer thermal insulation layer and the inner thermal insulation layer, and the space surrounded by the inner thermal insulation layer is a holding chamber for letting go. The wire is electrically connected to the transformer, and the transformer is electrically connected to the external power supply. A direction sensor that controls the power on and off of the circuit according to the direction change is installed in series on the circuit loop formed by the heating wire and the transformer. The utility model provides a power supply intelligent control device for the current charging hand warmer. The control device is provided with a direction sensor inside, and controls power on and off by sensing the direction change of the charging hand warmer through the direction sensor. When the user picks up the rechargeable hand warmer that is being charged, the direction sensor senses the change in the direction of the rechargeable hand warmer, and immediately controls the circuit to power off, effectively eliminating potential safety hazards and making the rechargeable hand warmer safer to use.
Description
Technical field
This utility model relates to a kind of charging hand warmer, belongs to technical field of living goods.
Background technology
In the winter time, people see TV, when listening leisure such as song because outside air temperature is very low, hand is felt cold and uncomfortable, in the time of especially outside both hands are placed on.Be head it off, have Crinis Carbonisatus to understand the charging hand warmer that can warm up hands.But there is following shortcoming in present charging hand warmer: pick up the charging hand warmer when warm up hands if user has forgotten to pull out power supply, the charging hand warmer is still charging, and safety has reduced greatly.
Summary of the invention
The purpose of this utility model provides a kind of charging hand warmer, has eliminated the deficiency that prior art exists.
The technical scheme that adopts of this utility model is to achieve the above object of the invention:
The charging hand warmer, comprise outer warming layer and interior warming layer, between described outer warming layer and the interior warming layer heating wire is installed, the container cavity of the space that surrounds of warming layer for being used for letting go in described, described heating wire is electrically connected with transformator, described transformator is electrically connected with extraneous power supply, it is characterized in that, the circuit loop that constitutes at heating wire and the transformator with good grounds direction that is installed in series changes the direction inductor device of this loop switching electricity of control.
As the further optimization to technique scheme, on the circuit loop that described transformator and described extraneous power supply are formed second switch is installed.
As the further optimization to technique scheme, the two ends of described direction inductor device are equipped with first switch that is connected in parallel with described direction inductor device.
This utility model provides a kind of power supply smart control device for present charging hand warmer, and this control device inside is provided with the direction inductor device, and the direction of experiencing the charging hand warmer by the direction inductor device changes to control switching.When user is picked up the charging hand warmer that is charging, the direction of direction inductor device impression charging hand warmer changes, and potential safety hazard has effectively been eliminated in control circuit outage at once, makes the charging hand warmer use safer.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of power supply smart control device of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, the charging hand warmer, comprise outer warming layer 3 and interior warming layer 2, heating wire R is installed between described outer warming layer 3 and the interior warming layer 2, the container cavity 1 of the space that surrounds of warming layer 2 for being used for letting go in described, described heating wire R is electrically connected with transformator TC, and described transformator TC is electrically connected with extraneous power supply U, and the circuit loop that constitutes at heating wire R and the transformator TC with good grounds direction that is installed in series changes the direction inductor device D of this loop switching electricity of control.
When charging hand warmer horizontal positioned, the circuit loop energising that direction inductor device D control heating wire R and transformator TC constitute, but charging hand warmer angle of inclination is during greater than default definite value (present embodiment is 15 °), direction inductor device D controls this loop and cuts off the power supply.
One deck flex foam 4 is laid in the outside of described outer warming layer 3.
Flex foam 4 has the effect of heat-insulation and heat-preservation, can also absorb certain heat and can not cause the periphery too hot and cause scalding hands, and the temperature that hand is experienced is also softer.
On the circuit loop that described transformator TC and described extraneous power supply U form second switch K2 is installed.
Second switch K2 is ordinary tap, effectively plays the effect of the whole charging hand warmer switching electricity of control.
The two ends of described direction inductor device D are equipped with first K switch 1 that is connected in parallel with described direction inductor device D.
First K switch 1 is emergency button, is in off-state generally speaking.Have only when direction inductor device D breaks down uncontrollable circuit switching electricity; Perhaps under special environment: such as the warm handbag of charging can't the horizontal positioned charging time, closed first K switch 1.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technical staff in the art, all should fall in the protection domain of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment according to design of the present utility model.
