Description

Measuring device for measuring the volume change of liquid contained in a water bottle

The present invention relates to a measuring device, and more particularly to a measuring device that can be used to carry a water bottle and measure the volume change of the liquid contained in the water bottle.

With the rise of health awareness, more and more people are concerned about whether their drinking water is sufficient. Ingesting enough water can promote metabolism and maintain good health, but people can easily forget to drink water in busy work and life. . Although there are already products on the market that can remind users to drink water, such as smart water bottles or smart coasters. However, the water sensor of the smart water bottle must be installed in a special water bottle or must be exclusively used with the special water bottle, so the product is expensive and cannot be applied to other water bottles or cups that are commercially available or used by users. Limited sex. While the smart coaster emphasizes that it can be applied to most water bottles or cups that are available in the market or for users, its separate design from the water bottle will not be convenient for the user to carry the coaster with the water bottle anytime and anywhere, and lose the original want The ability to monitor and remind the amount of drinking water at any time.

Accordingly, the present invention provides a measuring device that can carry not only a water bottle but also a water bottle and can be carried with the water bottle to at least solve the above problems.

In order to achieve the above object, the present invention discloses a measuring device for measuring a volume change of a liquid contained in a water bottle, which comprises a bottle sleeve and a weight sensing module, the bottle sleeve forming a first An accommodating space, a second accommodating space, and a first opening that communicates with the first accommodating space, the bottle sleeve has a telescopic elasticity, and at least a portion of the first accommodating space has an inner diameter smaller than the water bottle The outer diameter of the water bottle is stably contained in the first accommodating space when the water bottle is inserted into the first accommodating space, and the weight sensing module is disposed in the second accommodating space. The weight sensing module is configured to measure the weight of the water bottle and the liquid at different time points, and obtain a weight change amount according to the difference between the weight of the water bottle and the liquid measured at different time points, thereby judging The volume change of the liquid.

In summary, in the present invention, since at least a portion of the inner diameter of the bottle sleeve is smaller than the outer diameter of the water bottle and the bottle sleeve is elastically stretchable and deformable, when the user sets the bottle sleeve on the water bottle, the bottle sleeve and the water bottle The water bottle is tightly fitted to each other so that the measuring device can be firmly combined with the water bottle without being easily detached or tipped over, and is conveniently carried or used with the water bottle. In addition, when the user wants to replace the water bottles of different sizes by themselves, the bottle sleeves can be tightly matched with the water bottles according to the different water bottle sizes, that is, the measuring device of the present invention can be arbitrarily matched with water bottles of different sizes. In this way, the user does not need to change the original drinking habit and can replace the water bottle according to his needs, which is convenient to use. In addition, the measuring device can measure the volume change of the liquid contained in the water bottle to know the drinking water condition of the user, and achieve the purpose of health management.
