Abstract
The utility model discloses a portable hand warmer which comprises a bottom housing and an upper cover. A circuit board, a battery, a temperature controller and a heater are arranged in the bottom housing; a switch, a battery socket and an indicating lamp are arranged on the circuit board; the battery, the switch, the indicating lamp, the temperature controller and the heater are electrically connected in sequence to form a loop; the battery socket and the battery are connected in parallel; a metal heat conducting strip is further arranged outside the heater; the heater adopts a PTC heater or consists of a ceramic baseplate and an electric heating wire arranged on the ceramic baseplate; the battery adopts a movable battery or an ordinary dry cell; the battery socket adopts a USB socket or other sockets; and the metal heat conducting strip is provided with an elastic baffle preventing the heater from falling out of an upper cover. The utility model has the advantages of simpler structure, lower cost, better homoiothermy, and higher thermal transmission efficiency.
Description
Technical field
This utility model relates to a kind of heating installation, particularly a kind of light hand warmer.
Background technology
Existing hand warmer is owing to also be provided with the plastic cement connector between upper and lower covers, be used for fixing associated components, and between battery and heating element, also be provided with the reflect heat layer, its heating element adopts far-infrared electrothermal film usually, so, the structure more complicated of existing hand warmer, cost is also than higher, the demand that can not adapt to market well, and its temperature uniformity is bad, and heat transference efficiency is not high.Therefore, be necessary to make improvements.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide the light hand warmer that a kind of structure is simpler, cost is lower, temperature uniformity is better, heat transference efficiency is higher.
The technical scheme that the invention for solving the technical problem adopted is: a kind of light hand warmer, comprise drain pan, loam cake, be provided with circuit board, battery, temperature controller and heating element in the drain pan, described circuit board is provided with switch, supply socket and display lamp, described battery, switch, display lamp, temperature controller and the heating element loop that is electrically connected to form sequentially, described supply socket and battery are connected in parallel, described heating element also is provided with a metal conducting strip outward, and described heating element is ptc heater or is made up of ceramic substrate and the heating wire that is arranged on the ceramic substrate.
Technique scheme also can have following improvement project: described battery is mobile battery or general dry battery; Described supply socket is USB socket or other socket; Described metal conducting strip has and prevents that heating element from dropping out the outer elastic block piece of loam cake.
The beneficial effects of the utility model are: because described heating element also is provided with a metal conducting strip outward, described heating element is ptc heater or is made up of ceramic substrate and the heating wire that is arranged on the ceramic substrate, relative prior art, plastic cement connector and reflect heat layer have been saved, and heat without far-infrared electrothermal film, so structure of the present utility model is simpler, cost is lower; Because the temperature uniformity of ptc heater is better in other words because described heating element is made up of ceramic substrate and the heating wire that is arranged on the ceramic substrate, is provided with the temperature controller that keeps steady temperature in addition, so temperature uniformity of the present utility model is better; Because heating element is provided with metal conducting strip outward, described heating element is ptc heater or is made up of ceramic substrate and the heating wire that is arranged on the ceramic substrate, with respect to the far-infrared electrothermal film heating, its heat transference efficiency is higher, so heat transference efficiency of the present utility model is higher; In addition, because described battery is mobile battery or general dry battery, so this utility model charging or replacing battery are all very convenient; Because described supply socket is USB socket or other socket, so can pegging graft, uses on computers this utility model, socket power is very convenient.
Description of drawings
