The invention discloses an asymmetric hourglass and a student tooth-brushing cup with a timing function. The hourglass comprises an upper cavity and a lower cavity which are connected through a neck,sand is arranged in the hourglass, main bodies of the upper cavity and the lower cavity are spherical or cylindrical with the same diameter, the length of the upper cavity is smaller than that of thelower cavity, the tooth-brushing cup comprises a cup body, a cup bottom and a handle the side wall of the side, opposite to the handle, of the cup body protrudes towards the two sides to form a cylindrical cavity, the hourglass is arranged in the cylindrical cavity, the bottom of the cylindrical cavity extends to the cup bottom and is provided with an opening, and a cover plate is arranged in theopening. The upper end and the lower end of the hourglass are different in length, the short end is at the upper part, the long end is at the lower part, the lift distance is increased within the limited height, the waterfall-like visual effect is realized, the hourglass is applied to the tooth-brushing cup, the tooth-brushing concentration of students or preschool children is increased, the tooth-brushing cup is used for time reference, the three-minute tooth-brushing time is ensured, oral hygiene and health of students and children are well maintained, and oral diseases are prevented.

Description

technical field [0001] The invention relates to an asymmetric hourglass and a teeth-brushing cup for students with timing function. Background technique [0002] An hourglass, also called a sand clock, is a device for measuring time. The existing hourglass is basically a symmetrical structure, with the same shape and structure at both ends, so the head of the sandglass is also the same. If the head is to be increased, the length of the hourglass needs to be increased, which cannot meet the demand for increased head due to the limited length. [0003] Brushing teeth is to use toothbrush to remove dental plaque, soft dirt and food residue, and keep oral cavity clean important self-oral oral health method; it is also the most important means for people to remove oral dental plaque by themselves and prevent the occurrence, development and recurrence of periodontal disease. Choosing the right toothbrush, toothpaste, brushing method and proper brushing time can help control plaqu...

Problems solved by technology

But it is really difficult for ordinary people, especially students and preschool children, who do not have enough concentration to brush their teeth, and there is also a lack of practical timing devices for brushing scenes. things

Generally, brushing for two minutes is not enough, and one minute is a lot. Brushing for half a minute is considered normal. Inadvertent habits are often accompanied by a series of seven oral health problems, including dental caries, tartar, plaque, and gums. Bleeding, dentin sensitivity, dirty teeth, bad breath, etc. Also because there is no simple, practical and low-cost timing device in the current tooth brushing scene, some people forget the relatively normal time scale of three minutes, and it is no concept that brushing time is too long. Going to the other extreme, over-cleaning of the teeth will damage the protective layer of the tooth surface. Too short or too long brushing time will affect health, work and study, and unnecessary medical expenses.

[0004] Existing toothbrushing cups are generally only used to hold water, and additional alarm clocks or clocks are needed to time the brushing. The cost is high and troublesome to use, the battery needs to be replaced regularly, and there is also a risk of damage due to water ingress. Using a charging device and battery, In the humid environment of the bathroom, it is easy to cause the potential risk of heavy metal pollution, so it is not practical and the application scenarios are limited

There are also some brushing cups with hourglass on the market, which are more for decorative purposes, such as: ① An hourglass is placed in the handle. After holding the handle or handle, the hourglass can no longer be seen normally; the sand plays a role in timing; ② The cup body The exposed hourglass on the side plays the role of transparency timing, especially when washing the cup, or when the toothbrush is poured out of the remaining water, the hourglass will be broken if it touches a hard object such as a faucet, causing the user to be cut by the glass. Wound or debris sand contaminates bathroom environment

[0005] In addition, the existing toothbrushing cups still have the problem of dirt accumulating at the corners of the cup, which is particularly unhygienic after a long period of time, and it is very difficult to clean, which is a pain point in the market
