Direct cleaning of teeth and gingival sulcus

Technical field

The present invention relates to a tooth and gingival sulcus direct cleaning device capable of cleaning teeth and gingival sulcus by a water stream having a constant and uniform width and a constant and uniform thickness. Background art

Conventional washers that can wash teeth and gum grooves with tap water or other washing water include, for example, forming a handle portion of a toothbrush in a cavity, and connecting a conduit such as a PVC hose to an end of the handle portion. Connect the distal end of this conduit to a faucet such as water supply, introduce washing water into the handle of the toothbrush, and discharge the wash water from the bristle of the toothbrush or the tip of the handle, etc. It was common to clean the teeth and gingival sulcus along with the bristle of the toothbrush, and at the same time massaging the gums.

In the above prior art, when the teeth and the gingival sulcus are washed with washing water such as tap water, there is no particular contrivance in discharging the washing water, and the washing water is simply introduced into the oral cavity. The water flows into the teeth and gingival sulcus to be washed. As a result, foreign substances such as food debris and scales could not be effectively removed.

By the way, many foreign substances such as food debris and plaque adhere to the space between teeth after meals, especially in the sulcus, and even if the teeth are thoroughly washed with washing water and a toothbrush, these foreign meals are left behind. It has been difficult to completely remove the

Especially in the gingival sulcus, foreign substances such as food debris and plaque tend to accumulate, and a small amount of foreign stuff such as food debris and plaque remains in the teeth and gingival sulcus, and if it is left as it is, the teeth and gums Plaque adheres to the furrows, and caries first develops, leading to diseases such as gingivitis and alveolar pyorrhea.

It removes foreign substances such as food debris and scale, and adheres to teeth and gingival sulcus. Removal of plaque and effective massaging of the gums at the same time can prevent cavities, improve gingivitis, alveolar pyorrhea and other diseases, and cure the disease. The present invention cleans teeth and gingival sulcus by directly irradiating a water stream having a uniform and uniform width and a uniform and uniform thickness, and removes foreign substances such as food debris, plaque and plaque after eating. The aim is to provide a direct tooth and gingival sulcus that can be easily removed, effectively massage the gums, prevent caries, improve diseases such as gingivitis and alveolar pyorrhea, and cure the gums. And Disclosure of the invention

The direct washing apparatus for teeth and gingival sulcus of the present invention is a cylindrical or direct-washing apparatus body made of synthetic resin such as vinyl chloride or other flexible material having a long length, and is provided at one end with a tap or a water heater. A connecting portion for connecting to the faucet of the hot water supply facility is provided, and a washing water flow radiating port is provided at the other end. The radiating port can be crushed by finger pressure, and a long guide body for guiding the water flow is provided in the main body. With one end of the guide facing the radiation port, a water flow having a constant and uniform width and a constant and uniform thickness is freely radiated.

As a result, a water stream having a constant and uniform width and a constant and uniform thickness can be obtained. This water stream having a constant and uniform width and a constant and uniform thickness becomes a heavy water stream, collides with the teeth and gingival sulcus so as to pierce it, slightly opens the gingival sulcus and cleans the teeth and gingival sulcus, Easily removes foreign substances such as food debris and plaque after meals, and easily removes plaque attached to teeth and gingival sulcus, effectively massages gums at the same time, prevents tooth decay, gingivitis, alveolar It can improve and cure diseases such as pyorrhea.

That is, according to the present invention, since the guide body is provided in the cleaning device main body, the non-directional water flow supplied from the faucet collides with the guide body and is guided to be given a predetermined direction.

The present invention will be described in more detail with reference to the accompanying drawings.

In Fig. 1, one end of the direct spray cleaner body 1 consisting of a long pipe made of synthetic resin such as vinyl chloride or other flexible material, is connected to the faucet 2 of hot water supply equipment such as a water or water heater. A connection portion 6 having a connection port 3 is provided, and a tip pressing portion 8 having a washing water flow emission port 4 is provided at the other end.

As described above, since the main body 1 is made of a synthetic resin such as vinyl chloride or another flexible material, it is easy to handle and can freely clean desired teeth and gingival sulcus in the oral cavity.

The connection port 3 is provided with a notch 7 so as to be freely connected to the faucet 2. Due to the provision of the notch 7, the connection port 3 has a free size, and can be easily connected to the faucet 2 and can be freely connected to any kind of faucet 2.

There is a step between the connection part 6 provided with the connection port 3 and the cleaning device body 1. are doing. That is, the diameter of the connecting portion 6 is larger than that of the main body 1. Therefore, the tap 2 can be inserted into the tap 2 with one touch, and the tap 2 is prevented from being excessively inserted.

The cleaning device main body 1 is formed in a substantially cylindrical shape or narrowed at a certain angle with a gentle inclination toward the radiation port 4. Since the main body 1 has a cylindrical shape or a gentle inclination angle as described above, the flow of water passing through the main body 1 becomes good, and when the radiation port 4 is crushed by finger pressure during use, the main body 1 is pressed by the water flow pressure. There is no danger that 1 will vibrate violently and perform a dance-like action.

The distal end pressing portion 8 provided with the radiation port 4 is made to be able to be crushed by finger pressure by pinching it with a fingertip, so that it can be easily crushed even with a weak force and to easily obtain a plate-like water flow. A long V-shaped groove 9 is provided on both sides in the longitudinal direction. At the same time, the tip pressing portion 8 is provided with a plurality of V-shaped grooves 18 for preventing slippage in the vertical direction, since the tip pressing portion 8 is picked and operated with three fingertips of a thumb, an index finger, and a middle finger during cleaning. It is desirable that the V-shaped groove 18 be provided on the entire distal end pressing portion 8. By providing the V-shaped groove 18, it is easy to hold with a finger, and the cleaning work can be efficiently performed without slipping the finger.

A finger-hanging projection 19 is provided in a ring shape inside the tip pressing portion 8 and outside the main body 1, and holds the main body 1 between the ring finger and the little finger at the time of cleaning work, and By hooking on the part 19, the fingers can be easily pinched and the fingers are not easily fatigued. In addition, especially when cleaning the inside of the lower front teeth, the fingers can not be slipped and the cleaning work can be performed efficiently. .

As shown in FIGS. 2 and 3, a long guide 5 is provided in the main body 1 for guiding the washing water flow, and the guide 5 is provided over the entire length of the main body 1. And the outer end faces the end of the emission port 4. By providing the guide body 5 on the entire length of the main body 1 in this manner, the strength of the main body 1 is enhanced and, at the same time, the water flow can be stabilized.

The guide body 5 is formed in a long plate shape as a whole. It consists of a tray part 21 and an inclined part 22. The thickness is constant, but the width is narrowest in the vicinity of the connection part 6 and the slope is gentle from the point to the entrance of the tip pressing part 8, that is, the vicinity of the finger-hook projection 19. A guide portion 20 is formed so as to be slightly wider with the straight portion, and a straight portion 21 is formed so as to be straight in a straight line from the location concerned to the vicinity of the radiation port 4. In the vicinity of 4, an inclined portion 22 is formed by inclining both sides inward. Both ends of the guide 5 are not sharp and are formed flat.

Since the guide body 5 is formed in this way, as shown in FIG. 6, first, at the connection part 6 side, the water flow that was supplied from the faucet 2 and was a non-directional bubble was formed by the long guide part 2. It is guided by colliding with 0, and is given a direction that is slightly linear but has a gentle slope. The water flow given such a direction is further devised along the long guide portion 20 and can flow well in the main body 1.

The water flow guided along the guide portion 20 is then guided by the straight portion 21 to be given a linear direction, and furthermore, the water flow is formed at the inclined portion 22 immediately before the discharge port 4. Since the directionality toward the center is given, water flow cracking and bubbling are prevented, and a water flow having a uniform width and a uniform thickness can be obtained.

In other words, when the radiating port 4 is squeezed by finger pressure during use as shown in Fig. 4, the inside of one central part of the radiating port 4 and the upper surface of the guide 5 contact each other, and both ends of the radiating port 4 The part is opened. In this state, if the inclined part 22 is not provided, the water flow will flow straight, and will not be merged at the radiation outlet 4 but will be radiated separately from both ends naturally and completely broken However, it becomes foamy, and a water stream having a uniform width and a uniform thickness cannot be obtained.

However, since the guide body 5 is provided and the inclined portion 22 is provided in the main body 1 of the present invention, the radiation port 4 is pressed by a finger pressure during use. When crushed, the guide body 5 is located at the center of the radiation port 4 and guides the water flow to the center, and because it merges naturally, the water flow is prevented from breaking, such as jumping, splashing, and scattering, and is constant and uniform. Water flow having a constant and uniform thickness with the width of the outlet, i.e., a water flow having a constant and uniform width regulated by the width of the radiation port 4 and a constant and uniform thickness regulated by the thickness of the guide 5 A water stream having

This water stream having a constant and uniform width and a constant and uniform thickness becomes a heavy water stream, colliding with the teeth and the gingival sulcus in a piercing manner, and the gingival sulcus is slightly opened to clean the teeth and the sulcus. , To easily remove foreign substances such as food debris and plaque after meals, and to easily remove plaque attached to teeth and gingival sulcus, at the same time effectively massage the gums, prevent caries, prevent gingivitis, alveolar It can improve and cure diseases such as pyorrhea.

If this water flow does not have a constant and uniform width and a constant and uniform thickness, it becomes a light water flow and simply flows out to the teeth and gingival sulcus. It is not possible and cannot clean teeth and gingival sulcus.

One end of the guide body 5 is located near the connection portion 6, and the other end faces the end of the radiation port 4. This configuration prevents the gas fire of the water heater from extinguishing. That is, even if the radiation port 4 is crushed by finger pressure during use, strong water flow pressure is not temporarily applied to the main body 1 due to the presence of the long guide 5.

In Fig. 7, 1 is a long connecting pipe made of synthetic resin such as vinyl chloride or other flexible material, and has one end that can be freely connected to the faucet 2 of hot water supply equipment such as a tap or water heater. A connecting part 15 having a port 12 and a connecting port 14 of the main body 1 are provided with a connecting part 14 which can be freely inserted into the connecting part 3 so that the connecting part 3 of the main body 1 can be freely fitted.

The connection port 12 is provided with a notch 13, and the conduit 11 is formed with a V-shaped groove 17 together with a cutting position indicator 16. At the desired position.

By making the connecting conduit 11 having a desired length freely connectable to the main body 1, a washing operation can be performed at a desired place without selecting a place for washing.

Fig. 5 shows the hose band 23, which tightens the connection parts 6, 15 to the faucet 2. When not in use, it is locked by the band hook 10 and falls off from the main body 1. Is prevented. Although two band hooks 10 are provided on the main body 1 in the embodiment, one band hook may be provided. When the present invention has the above configuration, when used, first, the connection port 12 of the connection pipe 11 connected to the connection port 3 provided at one end of the main body 1 or the connection section 6 as necessary is connected to the water supply port. Or, it is fitted and connected to faucet 2 of hot water supply equipment such as a water heater. Then, the water is discharged into the main body 1 and the radiation port 4 is crushed by finger pressure to deform it into a substantially Y-shape, and then the radiation port 4 is directed toward a cleaning object such as a tooth and a gum groove. . In this case, by setting the distance between the emission port 4 and the target object to be about 30 to 5 O mm, the cleaning ability can be maximized and the cleaning work can be facilitated. A water flow having a constant and uniform width and a constant and uniform thickness, i.e., a water flow having a constant and uniform width of the radiation port 4 and a plate having a constant and uniform thickness of the guide body 5 Water flow is obtained.

This water stream having a constant and uniform width and a constant and uniform thickness becomes a heavy water stream and collides with the teeth and gingival sulcus so as to pierce it, slightly opening the gingival sulcus and cleaning the teeth and gingival sulcus And easily remove foreign substances such as food debris and plaque after meals, and easily remove plaque attached to teeth and gingival sulcus, at the same time effectively massage the gums, prevent tooth decay, prevent gingivitis, It can improve and cure diseases such as alveolar pyorrhea.
