具体实施方式Detailed ways

下面结合附图和实施例,对本实用新型进一步详细说明。其中相同的零部件用相同的附图标记表示。需要说明的是,下面描述中使用的词语“前”、“后”、“左”、“右”、“上”和“下”指的是附图中的方向,词语“底面”和“顶面”、“内”和“外”分别指的是朝向或远离特定部件几何中心的方向。The present utility model will be described in further detail below in conjunction with the accompanying drawings and embodiments. Wherein the same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top" "Face", "inner" and "outer" refer to directions toward or away from the geometric center of a particular part, respectively.

参照图1至2所示,本实施例的工作原理:使用者在喝水时倒在杯盖2处,而杯盖2内设有漏斗,在杯盖2翻过来时会带动漏斗内的沙子向下漏,而压力传感器4将检测到的压力值与对比装置内的额定数值进行比对,直至压力值与额定值一致时,压力传感器4传输给提醒组件5进行发声提醒使用者喝水,以防止时间太久使用者忘记喝而冰冷,同理,在使用者喝水完毕后,将杯盖2盖回时,沙漏3内的沙子再次向下漏,至压力值与额定值一致时,压力传感器4传输给提醒组件5,但下盖20的提醒组件5延迟一段时间进行提醒,延迟的时间可调控。Referring to Figures 1 to 2, the working principle of this embodiment: the user pours water on the cup cover 2 when drinking water, and the cup cover 2 is provided with a funnel, and when the cup cover 2 is turned over, the sand in the funnel will be driven It leaks downward, and the pressure sensor 4 compares the detected pressure value with the rated value in the comparison device. When the pressure value is consistent with the rated value, the pressure sensor 4 transmits it to the reminder component 5 to make a sound to remind the user to drink water. In order to prevent the user from forgetting to drink for a long time and it becomes cold. Similarly, after the user finishes drinking, when the cup lid 2 is closed, the sand in the hourglass 3 leaks downward again until the pressure value is consistent with the rated value. The pressure sensor 4 transmits to the reminder component 5, but the reminder component 5 of the lower cover 20 delays for a period of time to remind, and the delay time can be adjusted.

这种沙漏保温杯,包括杯盖2和杯体1,杯盖2螺纹套接在杯体1上端,杯盖2包括上盖22、下盖20、外侧壁21与内侧壁23,杯盖2内侧壁23与外侧壁21之间设有沙漏3,杯盖2外侧壁21和沙漏3皆采用透明材质制成,沙漏3上下端的上盖22与下盖20内皆设有触发组件,触发组件与提醒组件5通电连接。The hourglass thermos cup includes a cup cover 2 and a cup body 1. The cup cover 2 is threadedly connected to the upper end of the cup body 1. The cup cover 2 includes an upper cover 22, a lower cover 20, an outer side wall 21 and an inner side wall 23. The cup cover 2 An hourglass 3 is arranged between the inner side wall 23 and the outer side wall 21. The outer side wall 21 and the hourglass 3 of the cup cover 2 are made of transparent materials. The upper cover 22 and the lower cover 20 of the upper and lower ends of the hourglass 3 are both provided with trigger components. The trigger components It is electrically connected to the reminder component 5 .

透明材质可为玻璃材质制成,杯盖2与杯体1的螺接方式属于现有技术,本实用新型不在进行阐述。The transparent material can be made of glass material, and the screw connection method of the cup cover 2 and the cup body 1 belongs to the prior art, which is not described in the present invention.

作为改进的一种具体实施方式,沙漏3包括透明外壁和沙子,沙子位于透明外壁内,透明外壁与杯盖2外侧壁21采用真止口配合,沙漏3的中部设有环绕一圈均分设置的若干通孔30。As an improved specific embodiment, the hourglass 3 includes a transparent outer wall and sand, the sand is located in the transparent outer wall, the transparent outer wall and the outer side wall 21 of the cup cover 2 are matched with a true stop, and the middle of the hourglass 3 is provided with a circle and evenly divided a number of through holes 30.

经过测试设置10个通孔30,当沙漏3中的沙子完全漏完,杯盖2内的水温正好符合人体温度。After testing, 10 through holes 30 are set, and when the sand in the hourglass 3 is completely leaked, the water temperature in the cup cover 2 is exactly in line with the temperature of the human body.

作为改进的一种具体实施方式,触发组件包括压力传感器4以及对比装置,对比装置与压力传感器4一体化设置,若干个压力传感器4均分在沙漏3与上盖22和下盖20的连接处,且压力传感器4隐藏在上盖22和下盖20中,若干个压力传感器4分别与对比装置通电连接,压力传感器4通过对比装置检测后将信号传输给提醒组件5。As an improved specific embodiment, the trigger assembly includes a pressure sensor 4 and a comparison device, the comparison device and the pressure sensor 4 are integrally arranged, and the plurality of pressure sensors 4 are equally divided at the connection between the hourglass 3 and the upper cover 22 and the lower cover 20 , and the pressure sensor 4 is hidden in the upper cover 22 and the lower cover 20 , several pressure sensors 4 are respectively electrically connected to the comparison device, and the pressure sensor 4 transmits the signal to the reminder component 5 after being detected by the comparison device.

由于喝水需要将杯盖2翻过来,因此沙漏3也会自动向下渗漏,渗漏后沙子作用在压力传感器4上,进行检测,当压力传感器4检测的数值与对比装置的额定数值相同则证明沙漏3全部下漏,且杯盖2内的水温已达到人体所能适应的温度,在通过提醒组件5进行提醒使用者喝水。Since the cup cover 2 needs to be turned over to drink water, the hourglass 3 will also automatically leak downward. After the leakage, the sand acts on the pressure sensor 4 for detection. When the value detected by the pressure sensor 4 is the same as the rated value of the comparison device It proves that all the hourglass 3 leaks, and the water temperature in the cup cover 2 has reached the temperature that the human body can adapt to, and the reminder component 5 is used to remind the user to drink water.

本实用新型的比对装置引用申请号:CN201620193477.0的核查比对器。The comparison device of the utility model refers to the verification and comparison device of the application number: CN201620193477.0.

作为改进的一种具体实施方式,提醒组件5包括扬声器和位于扬声器内的内置蓄电池50,扬声器与若干个压力传感器4通电连接。As an improved specific embodiment, the reminder assembly 5 includes a speaker and a built-in battery 50 located in the speaker, and the speaker is electrically connected to several pressure sensors 4 .

下盖20的提醒组件5内设有延时器,下盖20提醒组件5的信号是下盖20的压力传感器4检测出的,而下盖20能够检测是在杯盖2在杯体1上的情况,而人体在刚喝完一杯水后,经过沙漏3下漏的时间,再次喝水有点过于频繁,因此设置延时器来解决此问题,而延时器为现有技术,结构本实用新型不过多说明。The reminder component 5 of the lower cover 20 is provided with a delay device, the signal of the reminder component 5 of the lower cover 20 is detected by the pressure sensor 4 of the lower cover 20, and the lower cover 20 can detect when the cup cover 2 is on the cup body 1. However, after drinking a glass of water, the human body will drink water too frequently after the hourglass 3 leaks. Therefore, a delay device is set to solve this problem, and the delay device is the prior art, and the structure is practical. The new model does not explain too much.

扬声器的结构属于现有技术,本实用新型不在进行阐述。The structure of the loudspeaker belongs to the prior art, and is not described in the present utility model.

作为改进的一种具体实施方式,内置蓄电池50与压力传感器4、对比装置和扬声器通电供电,杯盖2的上盖22与下盖20对应内置蓄电池50处设有通电插口。As an improved specific embodiment, the built-in battery 50 is energized with the pressure sensor 4 , the comparison device and the speaker, and the upper cover 22 and the lower cover 20 of the cup cover 2 are provided with power-on sockets corresponding to the built-in battery 50 .

通过通电插口进行充电,可持续使用,节约能源。Charging through the power socket, sustainable use and energy saving.

作为改进的一种具体实施方式,杯盖2内侧壁23的外端设有装饰层31,装饰层31与杯盖2内侧壁23一体化设置。As an improved specific embodiment, the outer end of the inner side wall 23 of the cup cover 2 is provided with a decorative layer 31 , and the decorative layer 31 is integrally provided with the inner side wall 23 of the cup cover 2 .

由于杯盖2外侧壁21和沙漏3皆采用透明材质制成,因此使用者能看到沙漏3内部结构,而单独的沙漏3过于单一,因此设置装饰层31增强美观效果。Since the outer side wall 21 of the cup cover 2 and the hourglass 3 are made of transparent materials, the user can see the internal structure of the hourglass 3 , and the single hourglass 3 is too simple, so the decorative layer 31 is provided to enhance the aesthetic effect.

作为改进的一种具体实施方式,杯体1的外壁处设有便于握合的弧形凹槽10。As an improved specific embodiment, the outer wall of the cup body 1 is provided with an arc-shaped groove 10 which is convenient for gripping.

便于人手拿取方便,使用更加便捷。It is convenient for people to take and use, and it is more convenient to use.

以上所述仅是本实用新型的优选实施方式,本实用新型的保护范围并不仅局限于上述实施例,凡属于本实用新型思路下的技术方案均属于本实用新型的保护范围。应当指出,对于本技术领域的普通技术人员来说,在不脱离本实用新型原理前提下的若干改进和润饰,这些改进和润饰也应视为本实用新型的保护范围。The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
