Description

Technical Field

[0001] The invention relates to an asymmetric hourglass and a student's toothbrush cup with a timing function. Background Art

[0002] An hourglass, also called a sand clock, is a device for measuring time. Existing hourglasses are basically symmetrical in structure, with the same shape and structure at both ends, so the head of the sand 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 while the length is limited.

[0003] Brushing teeth is an important self-oral health care method that uses a toothbrush to remove dental plaque, soft plaque and food residues to keep the mouth clean; it is also the main means for people to remove oral plaque and prevent the occurrence, development and recurrence of periodontal disease. Choosing the right toothbrush, toothpaste, brushing method and proper brushing time can help control dental plaque to the greatest extent, maintain oral health or extend the service life of restorations. To do a good job of oral hygiene, it is crucial to ensure a three-minute brushing time. The 333 brushing method is advocated in my country, which emphasizes that each brushing should last for three minutes and be clean and thorough. However, it is difficult for ordinary people to do it, especially students and preschoolers. They are not focused enough on brushing their teeth, and there is a lack of practical timing devices in the brushing scene. They mistakenly believe that regular brushing is a task to deal with others, rather than something they should do seriously and have fun. Generally, brushing for two minutes is a big deal, and one minute is also a lot. People think it is normal to just brush their teeth for half a minute. This careless habit is often accompanied by a series of seven major oral health problems, including caries, tartar, plaque, bleeding gums, dentin sensitivity, unclean teeth, bad breath, etc. Also, because there is no simple, practical and low-cost timing device in the current brushing scene, some people forget the relatively normal time scale of three minutes, and have no idea about brushing their teeth for too long, which is also going to the other extreme, resulting in excessive teeth cleaning and damage to the protective layer on the surface of the teeth. Brushing teeth for too short or too long will affect physical health, work and study, and unnecessary medical expenses.

[0004] Existing toothbrush cups are generally only used to hold water. An additional alarm clock or clock is needed to time brushing teeth, which is costly and inconvenient to use. Batteries need to be replaced regularly. There is also a risk of damage due to water ingress and other reasons. Using charging devices and batteries in the humid environment of the bathroom is prone to the potential risk of heavy metal pollution. Therefore, it is not practical and has limited application scenarios. There are also some toothbrush cups with hourglasses on the market, which are more for decorative purposes, such as: ① An hourglass is placed in the handle. After holding the handle or grip, the sand leaking from the hourglass can no longer be seen normally to play the role of timing; ② An exposed hourglass is used on the side of the cup body to play a transparent timing role. Especially when washing the cup, or when pouring out the remaining water after washing the toothbrush, a slight touch of the faucet or other hard objects will break the hourglass, causing the user to be cut by glass or the fragments of sand to pollute the bathroom environment.

[0005] In addition, existing toothbrush cups have the problem of dirt settling and accumulating in the corners of the cup, which is particularly unhygienic over time and very difficult to clean, which is a pain point in the market. Summary of the invention

[0006] The purpose of the present invention is to solve the deficiencies of the above-mentioned existing devices and to provide an asymmetric hourglass and a student toothbrush cup with a timing function. The upper and lower ends of the hourglass have different lengths, which increases the head distance within a limited height, increases the brushing concentration of students or preschool children and is used as a time reference, ensuring a three-minute brushing time, and well maintaining the oral hygiene and health of students and children and preventing oral diseases.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] An asymmetric hourglass, comprising an upper cavity and a lower cavity connected by a neck, with sand arranged inside, the upper cavity and the lower cavity are spherical or cylindrical with the same diameter, and the length of the upper cavity is shorter than that of the lower cavity. The outer contours of the two cavities are circular, the diameter of the middle connecting part gradually decreases to form a neck, the two ends and the end faces are transitioned by rounded corners, and the rounded corners in the upper cavity have a larger width, which is more conducive to observation. The upper cavity and the lower cavity have different lengths, and the upper cavity is just enough or slightly larger than the sand required to be accommodated, so that under the condition of limited length, the lift of the falling sand is maximized to enhance the visual effect.

[0009] Preferably, the upper cavity and the lower cavity are made of anti-fall glass with high transparency, high density, anti-fall, good safety and the light transmittance of eyeglass lenses, and the sand in the hourglass can be selected in different colors.

[0010] Preferably, the length ratio of the upper cavity to the lower cavity is between 0.6 and 0.75, which is close to the golden ratio and can best create a three-dimensional aesthetic feeling. The time for sand to leak from the upper cavity to the lower cavity is between 190s and 210s, such as 200s. In actual application, excluding the 20s time for squeezing toothpaste, pouring water, and adjusting the temperature, it is exactly the standard three-minute brushing time.

[0011] A student toothbrush cup with a timing function, the toothbrush cup includes a cup body, a cup bottom and a handle, the cup body is made of a transparent material, the side wall on the side of the cup body opposite to the handle protrudes to both sides to form a cylindrical cavity, an hourglass is built in the cylindrical cavity, the bottom of the cylindrical cavity extends to the bottom of the cup and is provided with an opening, and a cover plate is provided in the opening. It is equivalent to an hourglass embedded in the cup body, with good structural strength, no space occupation, and reduction of unnecessary structure. If the caliber of the cup body is consistent throughout, then the part of the cylindrical cavity protruding from the inner wall of the cup body is consistent in size from top to bottom, and the part protruding from the outer wall of the cup body is also consistent in size from top to bottom. If the cup body is an expanded structure, then the part of the cylindrical cavity protruding from the inner wall of the cup body gradually decreases in size from top to bottom, and the part protruding from the outer wall of the cup body gradually increases in size from top to bottom.

[0012] Preferably, the cup body and mouth between the handle and the cylindrical cavity are provided with two downward arc-shaped depressions. In order to allow the sand in the hourglass to flow back to the upper cavity and to allow the residual water in the toothbrush cup to flow out to prevent bacteria from growing, the toothbrush cup needs to be turned upside down. The arc-shaped depression is the contact point between the mouth and the cup when brushing teeth. When turned upside down, there is no external contact, which is more hygienic and forms an air channel to allow the dripping water to evaporate quickly.

[0013] Preferably, a convex ring is provided on the upper surface of the cover plate to form a step structure, and a circle of protruding limit rings is provided in the circumferential direction. The bottom opening of the cylindrical cavity is set to be a flared mouth, and a limit groove is provided on the inner wall of the flared mouth. The step structure and the flared mouth structure serve as installation stops. The limit ring and the limit groove prevent the cover plate from falling off after installation, and have the function of sealing and waterproofing. No glue, hot melt glue or other chemical glue is required for fixing, thereby ensuring the health and safety of users.

[0014] Preferably, a five-pointed star-shaped protrusion is provided in the convex ring. The middle of the five-pointed star-shaped protrusion is just aligned with the lower end surface of the hourglass. The valley bottom of the sand leakage effect can be used as a bonus item for the hourglass effect, and can be matched with the hourglass lift to improve children's concentration on brushing their teeth.

[0015] Preferably, the handle has holes at both ends, and the holes are used for inserting a toothbrush, and the toothbrush cup can be inserted whether it is placed upright or upside down.

[0016] Preferably, a plurality of protruding horizontal bars are provided on the inner side of the middle part of the handle, and the protruding thickness of the horizontal bars decreases from top to bottom, which facilitates gripping and prevents water slipping.

[0017] Preferably, an extension section is provided at the top of the cylindrical cavity outside the cup body, the width of the extension section gradually decreases from bottom to top, and the thickness gradually decreases from bottom to top and from the middle to both sides. The extension section is approximately triangular with rounded corners at the top.

[0018] Preferably, the bottom of the cup is sunken, and a certain number of convex points with arc surfaces are evenly distributed around the outer circle of the bottom surface of the cup. The bottom of the cup protrudes downward to form an arc surface, and when it is placed upright, dirt settles in the middle of the bottom of the cup, so that accumulated dirt can be found in advance and is easy to clean. The convex points increase friction and prevent slipping when the toothbrush cup is placed upright, and can also lift the bottom of the cup to allow water to evaporate and make the bottom dry.

[0019] The beneficial effects of the present invention are as follows: 1. The upper and lower ends of the hourglass are of different lengths, the shorter one is at the top and the longer one is at the bottom, which increases the lift distance within a limited height and has a waterfall-like visual effect;

[0020] 2. The hourglass and the toothbrush cup are well combined. The surface is smooth without any additional interference structure. It will not be damaged by touching other objects. The position of the hourglass is easy to observe. Combined with the transparent toothbrush cup, it can increase the concentration of students or preschool children when brushing their teeth and can be used as a time reference. It can well maintain the oral hygiene of students and children and prevent oral diseases.

[0021] 3. The sand draining time of the hourglass includes squeezing toothpaste, pouring water, adjusting the temperature, etc., to ensure three minutes of brushing time, and avoid brushing too short or too long;

[0022] 4. The toothbrush cup has a reliable structure, a single material, is easy to process and mold, has good structural strength, does not contain chemical products such as glue and hot melt adhesive, is safer and not afraid of falling, and has low cost of use;

[0023] 5. Use the handle of the toothbrush cup to place the toothbrush, so that the toothbrush cup can be placed upright or upside down;

[0024] 6. The bottom structure of the cup allows the dirt to settle in the middle of the bottom of the cup when the toothbrush cup is placed upright, making it easy to clean;

[0025] 7. The design of the mouth and bottom of the toothbrush cup allows the water in the placement to evaporate and dry quickly, whether the toothbrush cup is placed upright or upside down, to avoid bacterial growth, and to avoid contact with the outside world when it is inverted, which is more hygienic.
