Description

Dental floss

This creation relates to a dental floss, especially a dental floss with two winding tension modes, which is convenient to use at the molars behind the mouth and can be changed manually.

Oral hygiene affects physical health, and the first job to maintain oral cleanliness is to remove the residue from the teeth, and the best way to remove the residue is to use dental floss. However, because many people do not use dental floss, they can only accommodate in toothpicks or use floss sticks to remove food residue stuck in the teeth. However, toothpicks are easy to hurt the gums and will make the gap between teeth longer. Dental floss rods are not easy to hold and the floss is usually rough. It is difficult to grasp with force when used. A little carelessness can also cause damage to teeth and gums, especially in the molar gap between the inner side of the mouth. It is not easy. In addition, the dental floss rods need to be discarded after one use, which is not environmentally friendly. In order to prevent the spread of bacteria in the interdental space, the dentist recommends that you use clean dental floss segments in each interdental space, that is, if you follow the dentist's recommendations correctly If you use a dental floss rod, you need to use a dental floss rod for every tooth gap cleaning. The consumption of dental floss rods is self-evident.

Based on the above inconveniences, various types of dental floss holders and dental floss devices have been developed to help children or adults who do not use finger winding to clean the inner molars of the mouth or have difficulty using them, so that they can use dental floss. The device assists with dental floss to clean the gap between teeth, for the purpose of oral hygiene and health care.

Although there are many known types of dental floss on the market, there is still some need to improve the elasticity of the dental floss and the lack of convenience in use because of the actual operation and use. So far, the use of dental floss is still It cannot be popularized, and there is still much room for improvement and new creation.

The purpose of this creation is to provide a dental floss that is easy to use, especially convenient for use in the rear molars, conforms to the use habits of people's elbows and wrists, and is environmentally friendly and portable. This creation has developed two dental floss tension modes (tight-closing mode; elastic mode with resilience). Different dental floss tension modes can be selected according to the position of the tooth gap and the size of the tooth gap, so it is easier to make it with an appropriate angle and correct force. The dental floss is embedded in the gap between the teeth to avoid damage to the gums due to improper application of force. In addition, the dental floss head (or both ends of the dental floss) can be embedded and fixed firmly and not easy to loose; the length of the dental floss used in this dental floss device It is very short and can easily replace the floss roll, which is environmentally friendly, economical, and easy to use.

The following is an overview of the technical means used in the creation of the above-mentioned purpose and effect. The flosser of this creation can be simply distinguished into two parts, the floss brace and the grip. The two parts will be described separately below.

The dental floss brace includes a Y-shaped connecting arm and two left and right dental floss braces. An opening is provided below the front end of the dental floss brace for dental floss. The overall surface of the dental floss brace needs to be smooth and smooth, and the front end is slightly narrow. The rear is wider and the outer middle is slightly recessed inward to form a shallow groove. One or two positioning buttons are built on this shallow groove for dental floss to be wound thereon to fix the dental floss. The entire board surface is made of hard and non-fragile materials, so that various components such as the thickness of the board surface and the positioning buttons on it can be made as thin as possible while being firm and easy to use.

The positioning button on the dental floss brace is wound by a cap and fixed underneath for dental coils. It is composed of a journal. The positioning button of this creation is different from the dental floss that is used to fix the floss function by winding the spool. The positioning knob of this creation is short and has a small diameter, which suppresses the winding space and makes When it is wound, the dental floss overlaps and compresses each other so that it is not easy to loosen, and the creative positioning button draws a gap on the side of the cap for the dental floss head (or dental floss end) to be inserted and hung. The clamping of the inset gap can enhance the floss tightening effect and make the floss fixed and tightened without loosening.

The positioning buttons on the floss braces of this creation are designed in two modes, one is the fixed positioning button (fixed to the floss brace, which is the tight-locking mode), and the other is the movable positioning button (which is the flexible mode, which Moving up and down provides a moderate amount of flexibility). The movable positioning button is a new mode created by the creation, which provides a moderate elasticity of dental floss, it is easier to insert the dental floss into the rear molars, and it is easier to grasp the force to avoid gum damage.

The fixed positioning button can be fixed on the left and right dental floss braces (such as the second or third embodiment), and a floss segment can be wrapped around the fixed positioning buttons on the left and right ends to pull the floss firmly. Tightly supported on the dental floss, to achieve a good teething effect. If the floss extraction end is already provided with a fastening mechanism (as in the first embodiment), only a fixed positioning button is provided above the other end of the floss support plate, and the floss can be directly pulled out and passed through the floss support plate. The front end of the floss is pierced, and then the floss is wound on the fixed positioning button to achieve the effect of tightening the floss. In addition, if the elastic mode is adopted, one end of the dental floss can be wrapped around the fixed positioning button or fixed by a locking mechanism, and the other end can be wrapped around the movable positioning button, which can provide moderate elasticity and clean the gap between the rear molars. Convenience.

The movable positioning button is only provided on one end of the floss brace (non-floss extraction end, generally the right end), and the outside is a cap, which is fixedly connected with a journal, and the floss brace is provided with a shaft for the shaft. The neck passes through the strip hole that moves up and down, and the journal passes through the strip hole and is fixed to a bottom cover on the inside of the floss brace plate, so that the movable positioning button can move up and down in the strip hole without coming out. A sleeve is pressed on the journal of the movable positioning button Shrink spring, the other end of this spring is sleeved on the journal of the fixed positioning button above the movable positioning button. The elasticity of a compression spring must not be too loose, it must have a certain pressure, and its compressible limit must be controlled within a certain interval.

The design purpose of this movable positioning button and spring is: when the general dental floss is used in the molars with tight dental floss, the top surface of the molar is large and round, and the teeth and teeth have a certain arc, and the tension is tight. The dental floss often only touches the "point" where the tooth surface is more prominent. If the joint of this "point" is dense and real-time, it is difficult for the dental floss to get into the gap from this point, so the user needs to force down. If the force is not enough, the dental floss will not be easy to get stuck in. If the force is too large, it will easily hurt the gums or damage the teeth. However, when the floss is pressed down, due to the compression space of the spring, the floss placed on the tooth gap (especially the molar with a round shape behind the mouth) will follow the interface between the two molars (gap). An arc is formed. At this time, the contact between the dental floss and the tooth gap to be caught is "line" instead of "point". Because the contact range between the dental floss and the tooth gap is large, the user can adjust the grip Angle or slide back and forth, find the point where the gap is larger, and slide it into the gap, not only it is easier to insert the floss into the gap, but also to avoid gum damage caused by excessive force, and the elasticity of the floss is also relatively small. Does not damage the gums. In addition, the compression space of the spring must be limited so that the dental floss braces supporting the dental floss can only be pressed down to about half the height of the teeth.

There are two types of grips in this creation. The first is a shape similar to a toothbrush grip, and the grip is designed as a space for dental floss accommodation, and is integrated with the upper rod system. The reason why the floss grip is designed like the shape of a toothbrush grip is because people use toothbrushes to brush their teeth in the mouth every day, and they are very accustomed to using the toothbrush grip. It will be easier and easier to use fingers and wrists to hold, as well as the angle and force.

This kind of toothbrush-like grip is composed of the upper shaft and the floss-receiving grip. The handles are combined into one body or connected together. The grip bar is provided with a scraper, and the scraper is covered with a layer of soft protective material to avoid scratching the skin due to the sharp outer edge of the scraper. The scraper can be arranged at the joint between the top of the grip shaft and the floss brace arm in conjunction with the floss extraction method, so that the floss can be cut off after use.

There is a dental floss accommodating part at the end of the handle, which is connected with a slide rail and a slide groove. The slide groove is located below the handle part and can be integrated with the shaft above the handle. The slide rail end is connected with a card. After the slide rail is pushed into the chute, the buckle can be inserted into the pre-set buckle hole of the chute, and the outer wall of the two can be docked to close the internal space. A ratchet mechanism is provided on the inner side of the slide rail, and the floss roll is sleeved on the ratchet sleeve, so that the floss roll can only be rotated in one direction, and two grooves are opened above the slide groove, and a slide switch cover is mounted thereon. A stopper is connected under the slide switch cover. By pushing the slide switch cover to stop the stopper against the brake pawl of the ratchet, the floss can be positioned accordingly, and the slide switch cover is pushed back to make the stopper leave the pawl. The dental floss can then be pulled out in the forward direction.

After the dental floss is rolled out from the dental floss, the self-grip handle of the thread head runs along the hollow shaft and passes through the Y-shaped connecting arm to pass out of the dental floss brace. The positioning knob is wrapped around. When the dental floss is used up, you can replace it with a new coil. In order to easily pass the dental floss through the grip and out of the brace arm, this design has a lead pull ring, which can be easily pulled by the pull ring. The floss is threaded out for the purpose of changing the thread.

The floss accommodating method of this grip bar can also be different from the above-mentioned setting mechanism by ratchet, but simply set a floss accommodating slot at the end of the handle, and open a wire outlet on the slot cover for Floss extraction is used (as in the second embodiment).

This creation is also equipped with a collapsible grip bar. This grip bar can be used to close the whole of the dental floss into a shape similar to a drop of water or a pear, which is convenient for the carrier.

The collapsible grip bar is pivoted by a connecting rod to a water drop-like or pear-shaped shell Composition, the shell which can be used as a handle is formed by pivoting an upper cover and a base at one end and snap-locking the other end to form a accommodating space that can be opened and closed. There is a half-wheel-like protrusion at the center of the rear of the inside of the base. This protrusion is formed by shrinking from the bottom of the base to the inside of the base. From the bottom of the base, it is a retracted space for dental floss from the bottom of the base. A dental floss groove is formed, and a card groove is set in the groove, which is closed by an arc-shaped groove cover provided with a buckle, and a wire outlet is opened on the groove cover for floss extraction. Inside the base, such as the two sides of the raised part of the wheel, a hollow accommodation space is formed, which can be inserted into the Y-shaped two arms above the dental floss.

The handle housing cover is covered with a streamlined arc, which can cover the connecting rod and the dental floss support arm folded into the base; the handle housing cover and the base are pivotally connected at the rear end, both of which are narrow front and rear The wide type can be integrated into one, and can be docked and fastened with each other by a buckle structure provided at the front end. When you want to use the dental floss, you can pull the folded dental floss brace and connecting rod upward from the base to straighten it, and then retract the upper cover and fasten it to the base to form a handle of a drop-shaped shell; When you want to store it after use, you can bend the dental floss support arm and the connecting rod down to put it in the base, and the upper cover is closed and fastened. The entire floss device is closed into a water drop shape for carrying out.
