DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] like Figure 1-Figure 4The milk warmer comprises a heating cup 100 and a hot air component 200 for blowing hot air to the heating cup 100. The bottom of the heating cup 100 is provided with a notch 110, and also comprises a temperature measuring component 300 arranged opposite to the notch 110. The temperature measuring component 300 comprises a heat conducting plate 310 and a contact type thermal sensing unit 330 abutting against the heat conducting plate 310, and also comprises an infrared sensing unit 340. The heat conducting plate 310 is provided with an opening 320 matched with the infrared sensing unit 340. By setting the infrared temperature measuring unit, the temperature in the heating cup 100 can be directly measured without direct contact, which not only avoids the influence of the heating cup 100 rotation and other factors on the measurement. The temperature in the heating cup 100 can be displayed in time, and the contact thermal sensing unit 330 is set to continuously detect the temperature of the heat conducting plate 310. The heat conducting plate 310 and the milk bottle in the heating cup 100 are in contact with each other for heat conduction, and have strong anti-interference performance, that is, the measured value of the infrared temperature measuring unit can be verified by the contact thermal sensing unit 330, and the fluctuating value caused by external interference, such as the fluctuation of the measured value of the infrared temperature measuring unit caused by hot air, can be eliminated, so that the temperature can be measured accurately and quickly. Correspondingly, the correction coefficient of the contact thermal sensing unit 330 can also be obtained through the infrared temperature measuring unit, so that the temperature measurement can finally achieve fast measurement and obtain accurate temperature value.
[0020] like Figure 1 As described, at this time, the heat conducting plate 310 is located below the heating cup 100 and the top of the heat conducting plate 310 is lower than the upper hole of the notch 110, that is, the heat conducting plate 310 does not conflict with the milk bottle in the heating cup 100, and heat is transferred by thermal radiation without contact. The structure is simple and reliable. The temperature on the heat conducting plate 310 has a certain lag but has strong anti-interference performance. The infrared temperature measuring unit can directly measure the temperature in the heating cup 100. The contact thermistor unit 330 on the heat conducting plate 310 verifies the measured value of the infrared temperature measuring unit, and can eliminate the fluctuating values caused by external interference.
[0021] like Figure 2-5 The device also includes a base 360350 for mounting the heat conducting plate 310, forming a component, and also includes a fixing seat 400, on which a slide groove 410 is provided, and the base 360350 is slidably connected to the slide groove 410, and an elastic member is provided between the base 360350 and the slide groove 410, and the heat conducting plate 310 is located at an upper hole higher than the notch 110, that is, the entire component can be displaced on the slide groove 410, and the heat conducting plate 310 is located at an upper hole higher than the notch 110, that is, when a milk bottle is placed in the heating cup 100, the milk bottle will squeeze the heat conducting plate 310, so that the heat conducting plate 310 is always in conflict with the milk bottle, and the conduction efficiency is high.
[0022] like Figure 3 and Figure 5The heat conducting plate 310 comprises a main body 311 and an annular folded edge 312, the folded edge and the bottom of the main body 311 cooperate to form a flip-chip groove 313, the opening 320 is arranged in the middle of the main body 311, and the main body 311 is provided with a plurality of flip-chip holes for installing the contact thermistor unit 330 along the circumferential direction, which is convenient for installation and can reduce the interference of hot air to a certain extent, and the heat conducting plate 310 is provided with a plurality of protrusions 314 on the surface relative to the heating cup 100, which can reduce the contact area and reduce the influence of friction while maintaining a certain degree of heat conduction.
