Abstract
The utility model relates to the field of advertising machines and discloses a temperature-control advertising machine. The temperature-control advertising machine comprises an advertising machine body and at least one temperature-control fan, wherein the temperature-control fan is electrically connected with a main board in the advertising machine body and comprises a thermistor and a fan; and the thermistor is electrically connected with the fan and is a thermistor with a negative temperature coefficient. The temperature-control advertising machine has the function of constant temperature regulation and control, not only achieves a favorable heat dissipation function, but also saves energy and produces small noise; and the service life of the fan is prolonged correspondingly.
Description
Technical field
The utility model relates to the advertisement machine field, relates in particular to a kind of temperature control advertisement machine.
Background technology
Every can be in public or outdoorly simultaneously carry out demand to many consumers by the advertisement performance form, can reach the desired substance of promoting the sale of goods and all can be described as out-of-home media.Outdoor advertising can be divided into plane and three-dimensional two large categories: the plane billboard ad, bill and poster, the advertisement of wall wall, placard, vertically hung scroll etc. are arranged.Tridimensional advertisement is divided into neon bulb, signpost, advertisement machine and advertising tower lamp box advertisement etc.In advertisement, guideboard, poster are of paramount importance two kinds of forms, affect very large out of doors.Wherein, the development of advertisement machine is with rapid changepl. never-ending changes and improvements, is also trend and the trend of contemporary advertisement, its use audio frequency, video mix word alternately on liquid crystal display or LED screen, make displaying have more initiative, creativeness.But for advertisement machine, be that the time one will produce heat for a long time, therefore, DC fan generally all can be installed in present advertisement machine carry out thermolysis under always in running order.But under the impact of weather temperature, the temperature of advertisement machine work itself also can be affected thereupon, therefore in the summer of heat, needs the high rotation speed operation of fan; At weather colder winter or rainy weather, after only having the temperature of need to reach necessarily, just need fan to turn round.For the advertisement machine of existing DC fan of installing, not only can not satisfy the working temperature of advertisement machine the best, also not energy-conservation, simultaneously, due to uninterruptedly running always of fan, loss is large, the large problem of noise also can occur.
Summary of the invention
The purpose of the utility model embodiment is: a kind of temperature control advertisement machine is provided, has the effect of constant temperature regulation and control, not only play good thermolysis, the while is energy-conservation, noise is little, and the serviceable life of fan is corresponding prolongation also.
A kind of temperature control advertisement machine that the utility model embodiment provides comprises advertisement machine body and at least one temperature-controlled fan; Described temperature-controlled fan is connected with the intrinsic mainboard electricity of described advertisement machine.
Optionally, described temperature-controlled fan comprises thermistor and fan; Described thermistor is connected with described fan electricity.
Optionally, described thermistor is negative tempperature coefficient thermistor.
Therefore, use the technical scheme of the utility model embodiment, by on the advertisement machine body, temperature-controlled fan being set, be that described temperature-controlled fan can regulate and control voluntarily according to the temperature of different periods in the advertisement machine body, namely in the process that temperature slowly raises, the rotating speed of described temperature-controlled fan also improves accordingly; When temperature in the process that slowly descends, the rotating speed of described temperature-controlled fan also reduces accordingly, thereby the temperature that makes described advertisement machine body interior maintains normal operation in preference temperature, played good thermolysis, not only energy-conservation, noise is little, the simultaneously also corresponding prolongation in serviceable life of described temperature-controlled fan.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:
The structural representation block diagram of a kind of temperature control advertisement machine that Fig. 1 provides for the utility model.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
As shown in Figure 1, temperature control advertisement machine described in the utility model, comprise advertisement machine body 1 and temperature-controlled fan 2, described temperature-controlled fan 2 is connected with mainboard 11 electricity in described advertisement machine body 1, the number of described temperature-controlled fan 2 can come to determine according to the actual requirements, but generally adopts one to get final product, if in the extra high area of the sort of summer temperature, also suitably increase the number of described temperature-controlled fan 2, finally reach best radiating effect and get final product.Described temperature-controlled fan 2 comprises thermistor 21 and fan 22, and described thermistor 21 is negative tempperature coefficient thermistor, and namely along with the rising of temperature, its resistance value is along with reduction.One end of described thermistor 21 is connected with described fan 22 electricity, and the other end is connected with described mainboard 11 electricity.
When the temperature of described advertisement machine body 1 inside is opened when raising, the resistance value of described thermistor 21 is along with decline, thereby make the voltage at described thermistor 21 two ends also along with decline, but the voltage at fan 22 two ends that are attached thereto increases, thereby make the rotating speed of described fan 22 increase, thereby make the temperature in advertisement machine body 1 begin slowly to descend, thereby play thermolysis.In the process that the temperature in described advertisement machine body 1 slowly descends, the resistance value of described thermistor 22 is along with increase, thereby make the voltage at described thermistor 22 two ends along with increase, also reduce with regard to the voltage that makes described fan 22 two ends, thereby make the rotating speed of described fan 22 reduce.
In above-mentioned heat radiation process, keep all the time the intrinsic temperature of described advertisement machine in the working range of the best, not only energy-conservation, noise is little, also extend accordingly the serviceable life of described fan 22 simultaneously.
The above technical scheme that the utility model embodiment is provided is described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
