Abstract

The invention provides a hand warming device utilizing hot water, which relates to the field of warming in winter, in particular to hand warming. At present, the hand warming device is roughly divided into two types: a plastic hot water bag and an electric hand warming device. A plastic hand warming bag has strong smell, and a user feels uncomfortable when smelling the smell. The two hand warming devices both have the shortcomings of being hot in the beginning and short in heat preservation time. The technical scheme of the hand warming device utilizing the hot water is that double-layer metal is adopted, the space between the double-layer metal is vacuumized, boiled water is contained in a round pie space formed by inner layer metal, most heat can be transferred to outer layer metal only through infrared radiation to enable the outer layer metal to become hot, and the hand warming device can not be too hot due to slow radiation transferring. In order to further preserve heat, the outer layer metal is wrapped by a thick cloth cover clamping cotton so as to reduce heat scattering loss, and the cloth cover is sealed by a zip. The hand warming device utilizing the hot water has the advantages of being free of hand hurting, long in hand warming time and free of plastic smell.

Description

A kind of hand warmer that uses hot water
Technical field
The present invention relates to the field of warming oneself winter, particularly hand heating.
Background technology
Market hand warmer roughly has two types: plastic hot water bag and electric hand warmer.The warm handbag of plastics has very big taste, is hearing uncomfortable; These two kinds of hand warmers all exist temperature retention time not long, begin the very boiling hot hands that is prone to hinder, and electric hand warmer often adds an overcoat to be realized insulation and reduce the scald to hand.
Summary of the invention
The present invention is directed to the easy deficiency of scalding hand of hand warmer commonly used, design non-scald on hand and temperature retention time be the hand warmer of long water in full bloom.
The present invention solves the technical scheme that its technical problem adopts: long and avoid hot in order to overcome temperature retention time; Adopt double-level-metal, with the space evacuation between the double-level-metal, boiled water is contained in the cake space of inner layer metal formation; The heat of boiled water just greatly reduces through the part that conduction of heat distributes like this; Most heat can only be delivered to outer layer metal through way of infrared radiation, makes the outer layer metal heating, so owing to radiation delivery can not scald one's hand slowly.For further insulation, outer layer metal is wrapped up in the thicker cloth cover that accompanies Cotton Gossypii, reduce the heat distribution loss, with zipper seal cloth cover.
The invention has the beneficial effects as follows: do not hinder hands, the warm hands time is long, does not have the plastics taste.
Description of drawings
Fig. 1 is a hot water hand warmer sketch map.
Fig. 2 is a hand warmer cloth cover sketch map.
The opening that slide fastener wherein, 1, double-layer aluminium alloy hollow cake, 2, sealing plug, 3, the cloth cover of thick cotton, 4, is arranged.
The specific embodiment
Aluminium alloy cake 1 is a tank of double-deck evacuation, and 500 milliliters of moisture storage capacitys are used to store boiled water, use then sealing plug 2 with water-stop in container.Behind the space evacuation between the double-level-metal of container, the propagation of heat mainly is radiating mode, can slow down distributing of heat like this, prolongs temperature retention time, also can effectively avoid scalding hands.
The cake that hot water is housed 1 is packed in the cloth cover 3 of thick cotton, can more effectively be incubated, the time spent will the slide fastener of opening 4 do not pull on, prolong temperature retention time.Open slide fastener during use, hands is put in make hands warm in the cloth cover 3.

Claims (1)

1. a kind of hand warmer of hot water that uses of the present invention mainly is made up of double-layer aluminium alloy hollow cake, sealing plug and cotton-padded covering; It is characterized in that: the aluminium alloy cake is a tank of double-deck evacuation; 500 milliliters of moisture storage capacitys; Be used to store boiled water, use then sealing plug (2) with water-stop in container; The cake that hot water is housed (1) is packed in the cloth cover (3) of thick cotton, can more effectively be incubated, the time spent will the slide fastener of opening 4 do not pull on, prolong temperature retention time, open slide fastener during use, hands put in make hands warm in the cloth cover (3).
