Abstract
The utility model discloses a water temperature control type electric heating hand warmer, which comprises an external charger, a shell and a water injection inner container, wherein a water-proof material layer, an electric heating wire and an air outlet hole are arranged in the inner container; a socket of the external charger, a temperature control device, an indicating lamp and a storage battery are arranged in the water-proof material layer; and the electric heating wire and the storage battery, the storage battery and the temperature control device, the temperature control device and the indicating lamp, the temperature control device and the socket, and the socket and the electric heating wire are connected with each other through leads, so that a circuit is formed. The water temperature control type electric heating hand warmer is simple in structure, is easy to manufacture, and is low in cost; due to the adoption of the storage battery and the temperature control device, a long-time heat preserving function is realized easily; and microcomputer control and a temperature control design are adopted, so that the use safety is ensured.
Description
Technical field
This utility model relates to a kind of water temp controlling type electric heating hand warmer.
Background technology
Hand warmer uses in daily life frequently as a kind of heating tool, is liked deeply.Except safety, inexpensive, the function of permanent insulation is the most important evaluation foundation of hand warmer especially.
At present, the hand warmer kind on the market is various, can be divided into according to the range of application difference: for example massage hand warmer (patent No. 201120119155.9) but broadcast listening hand warmer (patent No. 201120119155.9) etc.; Mode difference according to charging is divided into: for example rechargeable hand warmer (patent No. 201130169447.9), hand self power generation hand warmer (201120185344.6) etc.
Summary of the invention
In order to overcome the shortcoming that existing hand warmer can not be incubated for a long time, this utility model provides a kind of water temp controlling type electric heating hand warmer.
The technical scheme that this utility model adopts is:
A kind of water temp controlling type electric heating hand warmer; The inner bag that comprises external charge device, shell and water filling; It is characterized in that: be provided with waterproof layer, heating wire and venthole in the said inner bag; The socket, attemperating unit, display lamp and the accumulator that comprise said external charge device in the said waterproof layer all are connected to form circuit through lead between said heating wire and said accumulator, said accumulator and said attemperating unit, said attemperating unit and said display lamp, said attemperating unit and said socket, said socket and the said heating wire.
Further, described attemperating unit comprises the chip that is used for thermometric temperature sensor and is used for circuit folding control.
Further, described shell outer fringe seal.
When this utility model uses, connect the charging of external charge device, display lamp is bright; When charging a battery, the water in the heating wire heating inner bag raises water temperature, and water temperature rise to maximum temperature threshold value heating wire stops heating; After water temperature rise to maximum temperature threshold value and accumulator were full of, accumulator stopped charging automatically, and display lamp goes out, and pulls up the external charge device.After using a period of time, when water temperature dropped to minimum temperature threshold, battery discharging made heating wire begin heating, stops heating when being heated to the maximum temperature threshold value, goes round and begins again, and reaches permanent heat insulation effect.
The beneficial effect of this utility model is embodied in: simple in structure, be easy to make, and with low cost; Utilize accumulator and attemperating unit just simple realization the function of permanent insulation, microcomputerized control, temperature control design has guaranteed the safety of using especially.
Description of drawings
Fig. 1 is this utility model overall structure sketch map.
The specific embodiment
With reference to Fig. 1; A kind of water temp controlling type electric heating hand warmer; The inner bag 2 that comprises external charge device 10, shell 1 and water filling; Be provided with waterproof layer 3, heating wire 8 and venthole 4 in the said inner bag 2; Comprise socket 5, attemperating unit 6, display lamp 61 and the accumulator 7 of said external charge device 10 in the said waterproof layer 3, all be connected to form circuit between said heating wire 8 and said accumulator 7, said accumulator 7 and said attemperating unit 6, said attemperating unit 6 and said display lamp 61, said attemperating unit 6 and said socket 5, said socket 5 and the said heating wire 8 through lead 9.
Further, described attemperating unit 6 comprises the chip 63 that is used for thermometric temperature sensor 62 and is used for circuit folding control.
Further, described shell 1 outer fringe seal.
When this utility model uses, connect 10 chargings of external charge device, display lamp 61 is bright; In the time of accumulators 7 chargings, the water in the heating wire 8 heating inner bags raises water temperature, and water temperature rise to maximum temperature threshold value heating wire 8 stops heating; After water temperature rise to maximum temperature threshold value and accumulator 7 were full of, accumulator 7 stopped charging automatically, and display lamp 61 goes out, and pulls up external charge device 10.After using a period of time, when water temperature dropped to minimum temperature threshold, accumulator 7 discharges made heating wire 8 begin heating, stop heating when being heated to the maximum temperature threshold value, go round and begin again, and reach permanent heat insulation effect.
The described content of this description embodiment only is enumerating the way of realization of inventive concept; Should not being regarded as of the protection domain of this utility model only limits to the concrete form that embodiment states, the protection domain of this utility model also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
