Referring to fig. 1, a hair dryer provided in this embodiment is applied to hair care, and includes: the temperature measuring device comprises a shell 10, a heater 20, a temperature measuring component 30 and an auxiliary temperature measuring component 40. Wherein the heater 20, the temperature measuring part 30 and the auxiliary temperature measuring part 40 are all arranged in the casing 10. The shell can be made of metal or plastic. The metal shell can better support the inner space, and the plastic material is easy to process and can be integrally formed through injection molding. And the plastic shell can also have good insulating and heat-insulating effects. The housing 10 may be manufactured by a 3D printing technique, which is a technique of constructing an object by printing layer by layer using an adhesive material such as powdered metal or plastic.
The heater 20 is arranged in the shell 10, the heater 20 is provided with a flow channel 210 for gas to flow through, and the heater 20 is used for heating the gas passing through the flow channel 210; specifically, the main principle of the heater 20 is to convert electric energy into heat energy, such as a heating wire or a heating sheet, which has high electrothermal conversion efficiency. When air flows through the flow channel 210 of the heater 20, the energy of the surface heated by the heater 20 is transferred to the air, the energy is transferred from the surface of the heater to the air, so that the temperature of the air is increased, the hair dryer blows the air with the increased temperature, and the high-temperature air can accelerate the evaporation rate of the moisture in the hair.
The temperature measuring part 30 is disposed in the flow channel 210, and the temperature measuring part 30 is used for measuring the temperature of the gas flowing through the flow channel 210; the auxiliary temperature measuring part 40 is disposed in the flow channel 210, and the auxiliary temperature measuring part 40 is used to calibrate the measurement result of the temperature measuring part 30. From this, it can be seen that both the temperature measuring member 30 and the auxiliary temperature measuring member 40 can measure the temperature of the gas. Usually, the measurement result of the temperature measuring part 30 is used as the main measurement result, and the measurement result of the auxiliary temperature measuring part 40 is used as the auxiliary measurement result. Or the measurement result of the temperature measurement component 30 is usually accurate, but in case of an obvious error in the measurement result, the measurement result of the auxiliary temperature measurement component 40 may be used as the standard, for example, the temperature measurement component 30 cannot perform measurement, or the measurement result has large fluctuation, which indicates that the temperature measurement component cannot normally operate, and at this time, the temperature is the accurate temperature of the gas through the measurement of the auxiliary temperature measurement component 40. Alternatively, the difference between the measurement results of the temperature measurement means 30 and the auxiliary temperature measurement means 40 is large, and the measurement results of the two may be averaged to obtain the average value as the temperature of the gas.
In the solution proposed in this embodiment, a heater 20 is disposed in the housing 10 of the hair dryer, the heater 20 is provided with a flow channel 210 for flowing gas, and the heater 20 heats the gas flowing through the flow channel 210. The temperature measurement component 30 and the auxiliary temperature measurement component 40 are arranged in the circulation channel 210, the temperature measurement component 30 and the auxiliary temperature measurement component 40 can measure gas in the circulation channel 210, the measurement result of the temperature measurement component 30 can be calibrated and corrected by arranging the auxiliary temperature measurement component 40, and the accuracy of the measurement result is further ensured.
In one embodiment, heater 20 includes an outer tube 220 and an inner tube 230 disposed within outer tube 220, with an annular flow channel 210 formed between outer tube 220 and inner tube 230. Through annular circulation passageway 210, gaseous being the annular and going out from the hair-dryer, avoid the air-out too concentrated, the angle of blowing is dispersed as far as, can obtain bigger blowing area when using the hair-dryer from this. In addition, the surfaces of the outer tube 220 and the inner tube 230 may also be used to heat the gas, so that when the gas is heated in the annular flow channel 210, the heating area of the gas can be increased as much as possible under the condition of heating the inner layer and the outer layer, and further, the heating efficiency can be increased.
In one embodiment, the thermometric component 30 and the auxiliary thermometric component 40 are located at the outlet end (not labeled) of the flow channel 210. The heated air in hair dryers is typically used to dry human hair and therefore it is desirable to know the temperature of the air applied to the hair as accurately as possible, which can cause damage to human hair or skin if the air temperature is too high and which can be ineffective to dry hair if the air temperature is too low. The outlet end of the hair dryer is closer to the hair, so that the temperature of the gas leaving the hair dryer can be known by arranging the temperature measuring component 30 and the auxiliary temperature measuring component 40 at the outlet end of the flow channel 210. In addition, the heating power of the hairdryer can be adjusted depending on the measured gas temperature, for example, the heating power can be reduced or heating can be suspended when the measured temperature is high. When the measured temperature is low, the heating power can be increased. Furthermore, a controller (not shown) is arranged in the hair dryer, the temperature measuring component 30 and the auxiliary temperature measuring component 40 are both electrically connected with the controller, the temperature measuring component 30 and the auxiliary temperature measuring component 40 transmit measured signals to the controller, and the controller controls the heating power and the on and off of the heater according to the received signals.
In one embodiment, the arc angle formed between the temperature measuring member 30 and the auxiliary temperature measuring member 40 in the annular flow passage 210 is 180 °. Specifically, the temperature measurement component 30 and the auxiliary temperature measurement component 40 are separately disposed at a position penetrating through the radial center of the annular flow channel 210, and it can also be understood that the temperature measurement component 30 and the auxiliary temperature measurement component 40 are disposed at positions far away from each other, so that the temperature measurement component 30 and the auxiliary temperature measurement component 40 can respectively measure the gas temperatures at different positions, and the situation of inaccurate measurement due to local over-high temperature is avoided. In other words, the temperature of the gas can be detected in a wider range by arranging the temperature measuring component 30 and the auxiliary temperature measuring component 40 at a far distance, so as to obtain the real temperature of the gas. In addition, the temperature measuring device is arranged on the arc with the angle of 180 degrees, and can also detect the abnormal condition that the local temperature of the heater 20 is too high or too low, for example, the temperature difference measured by the temperature measuring component 30 and the auxiliary temperature measuring component 40 is too large, so as to give a prompt to inspect and maintain the hair dryer.
In one embodiment, the hair dryer includes a plurality of heat patches 50, the heat patches 50 being spaced apart in the flow-through channel 210. That is, the heating unit is added, so that the gas can obtain heat more quickly. Further, it is known that the heating sheet 50 has a sheet shape, and thus a larger heating area can be formed, and the temperature of the gas can be rapidly increased. The material of the heating plate 50 includes fe-cr-al or ni-cr electrothermal alloy, and these existing materials have good electrothermal conversion efficiency and good oxidation resistance. The location of the heated gas in the flow channel 210 can be increased by the spaced arrangement of the heating fins 50 within the flow channel 210. Further, the distance between the adjacent heating sheets 50 is equal, that is, the heating sheets 50 are uniformly distributed in the circulation channel 210, so as to ensure the uniformity of the heating position, so that the overall heat balance of the gas can be ensured through the uniform heating position, and the local temperature is prevented from being too high or too low.
In one embodiment, the heating plates 50 are spaced to form a plurality of spaced spaces, and the hair dryer includes a plurality of auxiliary temperature measuring parts 40, and one auxiliary temperature measuring part 40 is disposed in each of the spaced spaces. Further, the distances between the adjacent heating sheets 50 are equal, so that a space with the same size is formed, and after the gas passes through the space with the same size, the equilibrium of the heated temperature of the gas can be effectively ensured.
In addition, in another embodiment, the hair dryer includes a plurality of temperature measuring parts 30, and a temperature measuring part 30 is disposed in each of the spaced spaces. And the temperature measuring parts 30 are uniformly arranged in the spacing space, so that the temperature of the gas can be measured more comprehensively. It should be noted that the specific number of the temperature measurement components 30 and the auxiliary temperature measurement components 40 can be set according to the number of the spacing spaces, so that the accuracy of temperature measurement can be ensured while the local temperature is ensured to be measured.
In one embodiment, the thermometric component 30 and the auxiliary thermometric component 40 comprise thermistors. It is understood that the temperature measuring principle of the temperature measuring part 30 and the auxiliary temperature measuring part 40 may be the same. Thermistors are a class of sensitive elements, and are classified into positive temperature coefficient thermistors and negative temperature coefficient thermistors according to the difference of temperature coefficients. Thermistors are typically temperature sensitive and exhibit different resistance values at different temperatures. The positive temperature coefficient thermistor has a resistance value which is larger as the temperature is higher, and the negative temperature coefficient thermistor has a resistance value which is lower as the temperature is higher, and they are both semiconductor devices. In addition, the temperature measuring part 30 and the auxiliary temperature measuring part 40 may further include other temperature measuring elements, such as a thermocouple or a thermal resistor. Furthermore, the temperature measurement principle of the temperature measurement component 30 and the auxiliary temperature measurement component 40 can be different, for example, the temperature measurement component 30 and the auxiliary temperature measurement component 40 include one of a thermistor, a thermocouple, or a thermal resistor.
Referring to fig. 2, in one embodiment, an air inlet 130 and an air outlet 140 are formed on a surface of the housing 10, the housing 10 further includes a main body 110 and a handheld portion 120, an included angle is formed between the main body 110 and the handheld portion 120, the air outlet 140 is disposed on the main body 110, the heater 20 is disposed in the main body 110 close to the air outlet 140, and the air inlet 130 is disposed on the main body 110 far from the air outlet 140. Therefore, the main body 110 is provided with a cavity which is through from front to back, and the air flows in the cavity of the main body 110, enters the main body 110 from the air inlet 130, is heated by the heater 20, and flows out from the air outlet 140. The included angle between the main body 110 and the handle 120 is the included angle between the direction of the outlet 140 of the main body 110 and the direction of the handle 120 facing the outlet 140. The included angle can be in three ranges, including one of an acute angle, a right angle, and an obtuse angle.
Referring to fig. 3, in one embodiment, the air inlet 130 is another embodiment, specifically, the surface of the casing 10 is provided with an air inlet 130 and an air outlet 140, the casing 10 further includes a main body portion 110 and a handheld portion 120, an included angle is formed between the main body portion 110 and the handheld portion 120, the air outlet 140 is disposed on the main body portion 110, the heater 20 is disposed in the main body portion 110 close to the air outlet 140, and the air inlet 130 is disposed on the handheld portion 120 far from the air outlet 140. Therefore, the cavity communicated to the main body part 110 is formed in the handheld part 120, gas firstly enters the handheld part 120 through the air inlet 130 of the handheld part 120 and then enters the main body part 110, is heated by the heater 20 and then flows out through the air outlet 140 of the main body part 110, and by the arrangement, when the hair dryer is used, the gas enters from the lower part of the hair dryer, and the air inlet 130 is arranged to be more hidden.
Referring to fig. 4, the present invention also provides a temperature calibration method for a hair dryer, the temperature calibration method being applied to the hair dryer, the temperature calibration method comprising:
step S10, controlling a heater to heat the gas flowing through the flow channel; specifically, the inside controller that is provided with of hair dryer, heater electric connection in controller, through opening and closing of controller control heater, simultaneously, the size of heater power can also be controlled to the controller. The hair dryer is provided with a fan with a motor and a switch, the fan is controlled to rotate by the switch when the hair dryer is used, and meanwhile, the heater is started to heat the air flowing through the flow channel of the hair dryer.
Step S20, controlling the temperature measuring component to detect the temperature of the gas to obtain a first detection value; specifically, the temperature measurement part is connected with the controller, and the temperature measurement part measures the temperature of gas, obtains first detected value, and the temperature measurement part transmits first detected value for the controller, and the controller still has the memory cell, and first detected value is stored in the memory cell.
Step S30, controlling the auxiliary temperature measuring component to detect the temperature of the gas to obtain a second detection value; specifically, supplementary temperature measurement part connection controller, supplementary temperature measurement part measure the temperature of gas, obtain the second detected value, supplementary temperature measurement part transmits the second detected value for the controller, and the second detected value is stored in the memory cell.
Step S40, difference processing is carried out on the first detection value and the second detection value, and a difference result is obtained; specifically, a first detection value and a second detection value are extracted in a storage unit, and the first detection value and the second detection value are subjected to difference processing to obtain a difference result, namely a difference result.
Step S50, judging whether the difference result is in the range of the preset threshold value; a preset threshold is preset in the controller, and usually the preset threshold is a range value, and within the range of the preset threshold, whether the difference result exceeds the standard or not is judged.
Step S60, if the difference result exceeds the range of the preset threshold, the second detection value is taken as the temperature measurement result, or the average value obtained by calculating the first detection value and the second detection value is taken as the temperature measurement result; it will be appreciated that there are two ways to calibrate the temperature measurements. In the first method, the second detection value is generally used when the temperature measuring unit does not operate normally as a result of temperature measurement. In the second mode, the average value obtained by calculating the first detection value and the second detection value is used as a temperature measurement result, so that the measurement values can be averaged, and the influence of the local temperature of the measurement point on the temperature measurement component is avoided.
In step S70, if the difference result is within the preset threshold range, the first detection value is used as the temperature measurement result. In short, the difference result does not exceed the standard, and the temperature measurement component can work normally, so the first detection value measured by the temperature measurement component is taken as the standard. In addition, even if the difference result is within the preset threshold value range, the average value calculated by the first detection value and the second detection value may be the temperature measurement result. Through the temperature calibration method of the hair dryer, after a first detection value obtained by measuring by the temperature measuring component is compared with a second detection value obtained by measuring by the auxiliary temperature measuring component, whether the temperature measuring component works normally or not can be judged according to a difference comparison result, and when the temperature measuring component works abnormally or the temperature measurement is not accurate enough, the measurement result is calibrated through the auxiliary temperature measuring component, so that the accuracy of the measurement result is effectively ensured.
