Abstract
The utility model provides a keyboard heating device heats piece, fin, fan, infra red ray induction unit, clip, power by casing, semiconductor and forms, the casing is semi -closed type container, the below at the casing is installed to the clip, the semiconductor heats the piece and installs in the position of casing by the export, and it generates heat and faces to casing inside, and the refrigeration face is located outside the casing, the fin is installed in the casing exit, the fin bottom surface heats closely fixed being in the same place of the piece face of generating heat with the semiconductor, fin extend portion is the bars column structure, the fan is installed inside the casing, and there is the air intake at its rear, the infra red ray induction unit is installed in the casing top, the power is installed in the casing outsidely. When specifically implementing, the infra red ray induction unit detects someone and uses the keyboard, and the start -up semiconductor heats the piece and heats to make the fan begin the air supply. The utility model discloses can the person provide hot -blast in order to use the keyboard for a long time cold season in the sky, alleviate the discomfort.
Description
Technical field
The utility model relates to consumer goods industries, particularly relate to a kind of computor-keyboard heating arrangement.
Background technology
Use in winter computer, particularly the work of long-time typing word, is often subject to cold puzzlement.Application number is the technology of utility model patent proposition " a kind of based semiconductor cooling piece carries out the keyboard of cooling and warming " of 201420694634.7, its deficiency existed is: 1, air outlet is positioned at the side of keyboard by user, when using keyboard, wind just in time blows in wrist location, helps little to alleviation finger nip in the air; 2, lack the function of monitoring keyboard service condition, when keyboard does not use, continue refrigeration or heat, producing unnecessary consumption.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, will provide a kind of keyboard heating arrangement, effectively can solve the inconvenience that the sky cold time uses keyboard.
The technical scheme that the technical matters that the utility model solves adopts is:
A kind of keyboard heating arrangement, be made up of housing, semiconductor heating sheet, heat radiator, fan, infrared induction unit, clip, power supply, described housing is type semienclosed container, and described clip is arranged on the below of housing, for whole keyboard heating arrangement is fixed on keyboard; Described semiconductor heating sheet quantity is more than or equal to one, is arranged on the position of housing by outlet, and its heating is facing to enclosure interior, and chill surface is positioned at outside housing; Described heat radiator is installed on housing outlets place, and each bottom surface of described heat radiator and each semiconductor heating sheet face that generates heat closely are fixed together, and described heat radiator extension is grating structure, is beneficial to air and passes through.Described fan is arranged on enclosure interior, and to heat radiator air-supply, there is air inlet at its rear.Infrared induction cellular installation is above housing air outlet, comprise infrared emission tube, infrared receiver tube, control assembly, described infrared emission tube is for launching infrared ray, described infrared receiver tube is used for receiving infrared-ray, when user brings into use keyboard, described infrared receiver tube receives reflected infrared, and described control assembly controls the heating of semiconductor heating plate, and starts fan air-supply.Described infrared induction unit detects whether someone uses keyboard at regular intervals, and when not receiving reflected infrared, described control assembly cuts off semiconductor heating sheet and fan power supply.Power supply is installed on outside, powers for giving semiconductor heating sheet, fan and infrared induction unit.
During concrete enforcement, keyboard heating arrangement is fixed on keyboard by one end relative with user, after opening power, infrared induction unit inspection uses keyboard to there being people, starts semiconductor heating sheet and heats, and make fan putting in blast.When unmanned use keyboard being detected, infrared induction unit cuts off semiconductor heating sheet and fan power supply, stops heating and blowing.
The beneficial effects of the utility model are: at sky cold season joint, in order to use keyboard for a long time, person provides hot blast, alleviate uncomfortable.
Embodiment
Show a kind of keyboard heating arrangement example structure front elevation in FIG, visible housing (1), semiconductor heating sheet (3), heat radiator (4), infrared induction unit (2), described housing (1) is type semienclosed container, described semiconductor heating sheet (3) quantity has two, be arranged on two side positions of housing (1) by outlet, its heating is inner facing to housing (1), and chill surface is positioned at housing (1) outward; Described heat radiator (4) is installed on housing (1) exit, described heat radiator (4) two ends and semiconductor heating sheet (3) heating face are closely fixed together, described heat radiator (4) extension is grating structure, is beneficial to air and passes through.Described infrared induction unit (2) is installed on above housing (1) air outlet, when bringing into use keyboard (5) for user, controls semiconductor heating plate (3) and heats.
Show a kind of keyboard heating arrangement example structure side view in fig. 2, visible housing (1), semiconductor heating sheet (3), fan (8), infrared induction unit (2), clip (6), power supply (7), described clip (6) is arranged on the below of housing (1), for whole keyboard heating arrangement is fixed on keyboard (5); Described semiconductor heating sheet (3) is arranged on the position of housing (1) by outlet, and its heating is inner facing to housing (1), and chill surface is positioned at housing (1) outward; It is inner that described fan (8) is arranged on housing (1), and there is air inlet at its rear.Described infrared induction unit (2) is installed on above housing (1) air outlet, when bringing into use keyboard (5) for user, control semiconductor heating plate (3) to heat, and start fan (8) air-supply.
During concrete enforcement, keyboard heating arrangement is fixed on keyboard (5) by one end relative with user, after opening power (7), infrared induction unit (2) detects that someone uses keyboard (5), start semiconductor heating sheet (3) to heat, and make fan (8) putting in blast.When unmanned use keyboard (5) being detected, infrared induction unit (2) cuts off semiconductor heating sheet (3) and fan (8) power supply, stops heating and blowing.
