Description

a spray toothbrush

technical field

The utility model relates to a spray toothbrush, which is mainly characterized in that it uses the gas-liquid two-phase atomization and crushing mechanism to clean teeth, especially between teeth.

Background technique

Many ancient civilizations in the world used to brush their teeth with twigs or small wood chips. Another common method is to rub teeth with baking soda or chalk. According to the American Dental Association, the world's first toothbrush was invented by Chinese Emperor Ming Xiaozong in 1498 by inserting short, hard pig hairs into a bone handle. The traditional Western method of cleaning teeth is rubbing and brushing with a rag, and this method has existed since at least ancient Roman times. Toothbrushes did not appear until the 17th century, and were not widely popular until the 19th century. In 1938, DuPont Chemical launched a toothbrush that used synthetic fibers (mostly nylon) instead of animal hair. The first toothbrush with nylon yarn as bristles went on the market on February 24 of that year.

Human ancestors have long had the habit of gargling and brushing their teeth. The earliest tool for cleaning the mouth was found in the tomb of the king of the Sumerian Ur city-state in 3000 BC—a tooth stick, which can last for two weeks. In ancient Greece and Rome, people used animal ashes as tooth powder to clean their mouths, and some primitive tribes used charcoal, salt water, fine sand, and branches to clean their teeth. , crush one end and make it into a brush shape, which is used to clean the gap between teeth and brush teeth. It is called Miswak, which is a natural toothbrush. According to the analysis of scientists, this branch contains fluorine and saponin, which can prevent tooth decay and relieve pain. effect.

The Chinese knew the importance of protecting their teeth more than 2,000 years ago. "Historical Records · Cang Gong Zhuan" has criticized that the cause of dental caries is "eating without rinsing". "Book of Rites": "Chicken crows, salty wash cough" shows that people have the habit of gargling. The ancients cleaned the mouth and teeth with fingers and willow branches. In the Dunhuang mural "The Sacred Picture of Laodu's Fork Head", there is a monk squatting on the ground, holding a mouthwash bottle in his left hand, and wiping his front teeth with the middle finger of his right hand. In the Tang Dynasty, people used willow branches to make brushes and dipped in medicine to wipe their teeth. In the Song Dynasty, some people advocated wiping their teeth with willow branches twice a day in the morning and evening. In the Yuan Dynasty, the term "toothbrush" was officially introduced. Guo Yu's poem said: "The toothbrush in Nanzhou is worth a gold for removing dirt and trouble." Characters use toothbrushes, and most people still brush their teeth with willow branches and tooth brushing powder developed from Chinese herbal medicines. According to archaeological findings, two bone toothbrush handles were unearthed in ancient tombs of the Liao Dynasty in my country more than 1,000 years ago. It can be seen that my country has a similar modern toothbrush more than 600 years earlier than Europe.

In Europe, the toothbrush was first invented in London in 1780 by British cobbler William Ellis. William Ellis was arrested by the London authorities because of the crime of sedition, and was subsequently put into the notorious Newgate Prison. Unlike most prisoners, he is good at thinking with his own brain. One morning, he was scrubbing his teeth with a small piece of cloth in the usual way, when a thought suddenly came into his mind: Is it more convenient and effective to use a small brush to brush his teeth than to wipe his teeth with a cloth? Woolen cloth? When having dinner, he secretly put a meat bone into his pocket and brought it back to his cell, and asked a friendly guard for some bristles. That night he ground the bone into a thin rod, drilled holes in it, and inserted bunches of pig bristles into the holes, trimming them neatly. In this way, the world's first toothbrush was born in prison! After leaving prison, Ellis started his own toothbrush factory. He has been very successful because people are willing to use toothbrushes instead of the original small piece of cloth. The company that Edith founded still makes toothbrushes today.

Toothbrushes can be divided into ordinary toothbrushes, spray toothbrushes, electric toothbrushes and ultrasonic toothbrushes according to the principle of action.

The shape of the brush head of ordinary toothbrushes is generally square and diamond. The square brush head effectively cleans every surface of your teeth. The end of the diamond-shaped brush head is designed to be sharper than the square shape, which is easier to clean deep into the oral cavity. A toothbrush has a brush head of any shape, which can clean teeth, but the size of the brush head must take into account factors such as the size of the mouth, the degree of mouth opening, and personal habits. Try to use a small brush head so that it can penetrate deep into the mouth, ensure flexible rotation, and clean the rear teeth. But there is no uniform standard. Children's oral cavity should choose a children's toothbrush that matches their age.

Spray toothbrush is a tool for atomizing liquid toothpaste. When brushing teeth with a spray toothbrush, it can spray liquid toothpaste onto the teeth. Spray toothbrushes are divided into manual spray manual spray toothbrush toothbrushes and electric spray toothbrushes.

The manual spray toothbrush is to add a toothbrush head to the compressed bottle, and the bottle body is used as a toothbrush handle. The technical feature of the manual spray toothbrush is that liquid toothpaste is housed in the compressed bottle of the toothbrush handle, a toothpaste channel and a spout are arranged on the toothbrush head, the spout is hidden in the toothbrush bristles, and the liquid toothpaste is ejected from the spout; There is a soft rubber one-way valve to block the spout. The soft rubber one-way valve is used for sealing the spout to prevent bacteria and saliva from entering the toothpaste channel and ensure the quality of the toothpaste in the toothpaste channel.

The electric spray toothbrush is a can of aerosol-squeezed toothpaste installed in its toothbrush handle. There is a toothpaste channel and an electric spray toothbrush nozzle on the toothbrush head. The valve blocks the spout, and the aerosol squeezed toothpaste pushes the soft rubber one-way valve to spray out from the spout under the action of air pressure. After the electric toothbrush is turned on, the aerosol-squeezed toothpaste will be sprayed on the teeth regularly and quantitatively. No matter how the bristles of the electric toothbrush vibrate, the aerosol-squeezed toothpaste can fully contact the teeth and fully exert its effect. After the liquid toothpaste is used up, you can put it in another can.

Electric toothbrushes are divided into many kinds along with the improvement of technology, generally clean teeth by vibration and rotation, and some high-grade ultrasonic instruments are housed, clean teeth by pulse and water spray. Ordinary electric toothbrushes that sell for tens of yuan on the market just vibrate and rotate, and their frequency and strength are very large, and they are fixed. Ultrasonic toothbrushes are generally harmless to teeth and gums, and they clean teeth very well, but they are expensive.

The bristles of electric toothbrushes use rotational motion, so they need to stay on each tooth surface for a period of time, and three tooth surfaces must be taken into account to achieve the purpose of cleaning teeth, which is time-consuming. Therefore, you need to have enough patience when using an electric toothbrush to really clean your teeth. If you just put the toothbrush into your mouth and move it up and down asynchronously, you can't thoroughly clean the bacteria in special parts such as the pits and grooves of the teeth, the gingival sulcus and the gap between the teeth, which will also cause dental diseases. Proper use of electric toothbrushes does have the effect of removing plaque, preventing dental caries and periodontitis, but these effects are no different from ordinary toothbrushes. Electric toothbrushes have only changed the way people brush their teeth, and cannot completely replace the effect of cleaning teeth. It’s just that when many people brush their teeth manually, due to improper methods and excessive brushing force, it is easy to cause unnecessary damage to teeth and gums, while electric toothbrushes can reduce this damage and massage the gums. However, if the electric toothbrush is used in the wrong way, it will cause damage to the teeth. Usually all be to brush up and down actively with common toothbrush, i.e. vertical brush. However, the vibration frequency and strength of electric toothbrushes are relatively fixed. When rotating, it is similar to a horizontal brush on the surface of the teeth, which may cause certain wear and tear on the teeth, and may seriously cause periodontitis. If the tooth itself is not very good, such as when suffering from gingivitis and periodontitis, it is best not to choose an electric toothbrush.

Ultrasonic toothbrush Ultrasonic toothbrush is a new type of toothbrush after ordinary toothbrush and electric toothbrush. Ordinary toothbrushes and electric toothbrushes remove the impurities and germs on the tooth surface when the bristles touch the tooth surface and rub against the tooth surface. For the places where the bristles cannot reach (such as: inside the gum pocket, between the teeth, etc.), germs and Unclean things are helpless, and these parts form a blind area for brushing teeth and a refuge for bacteria. Ultrasonic toothbrush uses the cavitation effect of ultrasonic energy in the periodontal to remove periodontal bacteria and unclean substances, and its cleaning range can cover all parts of the periodontal. The dual-frequency ultrasonic toothbrush is an ultrasonic piezoelectric sensor built in the brush head The energy device is excited by the MCU drive circuit installed in the hollow brush handle to generate vibration and emit ultrasonic energy. Ultrasonic energy is transmitted to the surface of teeth and gums through the bristles of the brush head. On the one hand, it loosens the adhesion of plaque, tartar and fine tartar to the teeth, and destroys the parasitic reproduction of bacteria in the gum pockets and hidden places on the tooth surface. At the same time, through The ultrasonic energy transmitted by the bristles that touch the gums to the surface of the gums further penetrates into the gums, acts on the cell membrane, accelerates blood circulation, promotes metabolism, inhibits inflammation of the gums and bleeding of the gums, and prevents gum recession.

Contents of the invention

The utility model relates to a spray toothbrush. The working principle of this spray toothbrush is very different from previous spray toothbrushes. The previous spray toothbrush is essentially a water spray toothbrush, using the pressure of the tap water pipe or using other equipment to increase the water pressure, so that the water is sprayed out from the nozzle hole. This jet of water is usually called a jet, and the jet also produces atomization, but basically relies on the kinetic energy of the jet to scour the teeth. Just like we wash our cars with water. And the spray toothbrush described in the utility model, its working principle is to utilize the negative pressure that high-pressure high-speed airflow produces, water is thrown upwards, and is rapidly atomized under the action of airflow, and this bubble explodes after impacting teeth, and produces Momentum and shock waves loosen food debris on or between the tooth surfaces and flow away under the flow of water.

This spraying toothbrush described in the utility model comprises a small-sized air pump, three functional support auxiliary devices of a connecting hose and a pointed-mouth water injection bottle. Wherein the small air pump is powered by the household 220 volt alternating current port to compress the air, output adjustable pressure gas, and provide pneumatic energy for the spray toothbrush. The connecting hose is used to connect the small air pump to the spray toothbrush and the sharp-nosed water bottle is used to fill the spray toothbrush with liquid water for atomized cleaning.

This spray toothbrush described in the utility model comprises a hose interface (5) at the tail, a water storage chamber (6), an air passage (7), bristles (8), a spray port (9), and an air outlet (10) and brush head (13). Its material body is plastic, but the bristles are made of nylon.

The spray toothbrush of the utility model is characterized in that: the water storage chamber (6) is cylindrical, with a diameter of 2 to 3 centimeters, a length of 10-12 centimeters, and a wall thickness of 2 to 3 millimeters. In this way, the water storage capacity of the toothbrush is enough to produce a spray for 5 to 10 minutes, which meets the requirements of ordinary people for brushing time. If there is any remaining water storage chamber after brushing the teeth, it can be thrown out forcefully. The wall thickness of the water storage chamber is required to be able to withstand the pressure of the working water pressure.

The spray toothbrush of the utility model is characterized in that: the inner diameter of the air passage (7) is 3 to 6 millimeters, and the wall thickness is 2 millimeters. In addition to ensuring the safe passage of high-pressure and high-speed gas, the airway also has the effect of increasing the speed of airflow due to the narrow outlet.

The spray toothbrush described in the utility model is characterized in that: the number of the spray mouths (9) is 2, conical, located in the middle of the brush head (13), and the height is half of the bristle height. The tapered nozzle hole is beneficial to the high-speed gas ejected from the air outlet (10) to generate a vortex, and bring more water to rise to form more air bubbles, thereby cleaning the teeth more effectively. If the height of the spray opening is too low, it is not conducive to the formation and refinement of the spray, because the bristles will break up these fine mist and make it recondense into water. And if the height of the spray port is too high, it will affect the normal brushing process.

Spray toothbrush described in the utility model is characterized in that: described air outlet (10) has two, is opened on the wall surface of airway (7), and the position is just opposite spray mouth (9), and diameter is 1.5 millimeters. The thin air outlet facilitates the formation of high-velocity fluid.
