Abstract

The utility model provides a hot wind hand drying machine which is in the shape of a prismatic box. The upper part of the box is provided with an axial flow low noise wind leaf (1), one side of the box is provided with a PTC ceramic heater (2), and the wind leaf (1) is mutually connected and electrified with the PTC ceramic heater (2). The utility model has the advantages of power consumption saving, small volume, safety, durability and moderate price, and is widely used for common people to warm hands.

Description

The hot blast hand dryer

Technical field:

The utility model relates to a kind of heating installation, is specifically related to a kind of hot blast hand dryer.

Background technology:

For some like surfing the Net, game machine and happiness sit the people who handles computer in bed for a long time, hand is cold especially when pressing mouse or keyboard with hand when winter, weather was cold, a small-sized warmer is preferably arranged, therefore be necessary to provide a kind of economize on electricity, safety, little, durable, the moderate hand warming device of volume.

Summary of the invention:

The purpose of this utility model is to provide a kind of small and exquisite, safe, effective hand dryer.

The utility model provides a kind of hot blast hand dryer, it is that a prismatic is box-like, a kind of axial flow low noise fan blade is adorned in the top of box, side at box is equipped with a kind of PTC ceramic heating, when the two interconnects and switches on, the air communication that fan blade produced is crossed the PTC ceramic heating material and is become gentle air-flow and blow to operating computer keyboard or mouse on hand.

The utility model power consumptive province, volume are little, safe, durable, moderate, extensively are suitable for the warm hand function of ordinary people.

Below in conjunction with drawings and Examples the utility model is further specified.

Description of drawings:

Fig. 1, structural representation of the present utility model

The specific embodiment:

The utility model provides a kind of hot blast hand dryer, as shown in Figure 1, be that a prismatic is box-like, a kind of axial flow low noise fan blade 1 is equipped with in the top of box, side at box is equipped with a kind of PTC ceramic heating 2, when the two interconnects and switches on, the air communication that fan blade 1 produced is crossed PTC ceramic heating 2 and is become gentle air-flow and blow to operating computer keyboard or mouse on hand.

The PTC pottery is a kind of semi-conducting material of negative temperature coefficient: its resistance value and temperature are inversely proportional to, resistance is also big more when its temperature is high more, it can play the effect of automatic temperature-adjusting control like this, its electrical power is bigger when just using intensification, regularly power can automatic decline because its own interior resistive is big and when its own temperature reaches one, at this moment because diminishing of power and heat that it produced diminishes, and heating-up temperature reduces, cross when its heating-up temperature and can cause its resistance decreasing when low again, and cause electrical power to become big, its temperature is raise, so just form temperature automatically controlled effect.

Claims (1)

1, a kind of hot blast hand dryer is characterized in that this hand dryer is that a prismatic is box-like, and fan blade (1) is equipped with in the top of box, and a side of box is equipped with PTC ceramic heating (2), and the two interconnects and switches on.
