Description

Description PORTABLE DENTAL DEVICE OF TREATING DUST

Technical Field

[1] The present invention relates to a portable dental device of treating dust

Background Art

[2] The present invention relates to a portable dental device of treating dust, and in particular to a portable dental device of treating dust which is easily engaged at a temporal table used in a dental hospital and is portable and is engaged with an air spray device for thereby significantly enhancing a convenience.

[3] When a temporal tooth is manufactured in a dental hospital, a resin powder and a chemical liquid are mixed with each other and are molded in a shape of a tooth of a patient. In the middle of the above manufacture, a grinding tool is used to grind the mold. At this time, a harmful chemical material is produced owing to a heat generating in the course of the grinding. A lot of dust is produced, so that the dust may be inputted into a respiratory organ of a doctor or a patient. In addition, when a new denture is manufactured or an old denture is repaired, a grinding work is performed. At this time, a lot of dust and chemical substance are produced for thereby affecting a respiratory organ. In particular, when a denture is manufactured, a lot of bacteria stuck on a denture is cut and spread into air and is inputted into a respiratory organ of a doctor and a patient for thereby causing a direct infection. A dust treating device is disclosed for preventing the above problem in the course of a special dental work. In the above dust treating device, a head unit is engaged at a washstand, and a motor is engaged at a lower side of the washstand for thereby sucking dusts with a driving force of the motor and filtering the same.

[4] The above conventional dust treating device has the following problems.

[5] 1) Since an unnecessary cutting device is needed, the price is high.

[6] 2) A large size motor generates a lot of noises.

[7] 3) The entire size is big, and it is impossible to move the system owing to a structure of a dental room, and it is impossible to do a dust treatment work in a state that a patient sits on a unit chair.

[8] 4) Wheels are engaged at a lower side for movement. But, a head unit should be fixed at a structure such as a washstand, so that a work is impossible depending on a height and a body style of a doctor. In case that two patients are examined concurrently, it is impossible to achieve a desired work.

[9] 5) A dust should be removed from a cut portion at a target portion, so that a next cutting work can be performed efficiently. In this case, a work assistant should spray air beside the doctor. Since the air sprayer is not integrated, an assistant is needed for increasing the cost of workers.

[10] So as to overcome the above problems, a movement of a head unit is improved.

According to the Korean utility model publication number 96-13372 of "Manmade dental worktable for dust suction by doctor", a body having a motor and a conical plate are connected via a wrinkle tube for thereby improving a movement of a conical plate, so that it is possible to enhance a work convenience. However, according to the above conventional art, a large size body is unchanged except a connection of a conical plate to a body via a wrinkle tube, so that there are still problems. According to a Japanese publication, there are many disclosures in which a head unit is improved, and a dust process technology of a body is disclosed. However, the above disclosures fail to teach an integration with the air spray device, and a mobility enhancement of a body. Disclosure of Invention Technical Problem

[11] Accordingly, it is an object of the present invention to overcome the above problems.

[12] It is another object of the present invention to provide a simple dust treatment device in which the sizes of a head unit and a body are reduced, so that a portability and a mobility are enhanced, and a volume is reduced, an a vacuum process motor is not needed for preventing noises, and a fan having a built-in motor is designed to suck dusts with the help of rotation of the fan.

[13] It is further another object of the present invention to provide a device for treating dusts in which a lighting device is engaged at a head unit, so that a dentist's workability is enhanced, and when an amount of dust is small, it is possible to easily treat dusts without using a driving force of a body.

[14] It is still further another object of the present invention to provide a means for treating micro dusts and implementing an air purification, so that a driving force can be efficiently used.

[15] It is still further another object of the present invention to maximize a space use by providing a space in which a work tool can be stored, while allowing a body and a head unit being separate from each other for thereby achieving an easier cleaning work.

Advantageous Effects

[16] As described above, the portable dental dust treatment device according to the present invention has the following advantages. [17] 1) The dusts and bacteria and harmful chemical substances producing during the denture repair and temporal tooth process, removal of old metallic implant, etc. and the water are sucked, so that it is possible to protect the patient and doctor from pollution.

It is possible to prevent 100% the implant and temporal tooth from flying to the outside by the rotation device and missing. [18] 2) A low and high speed engine can be used, which are provided at a conventional dental unit system.

[19] 3) The body is light and portable, it is easy to use at any place.

[20] 4) It is made in a javara type, so that anyone can freely use irrespective of the position and body state of the doctor, so that a work environment can be enhanced. [21] 5) Since an air spray unit is provided, an assistant person for blowing dusts is not needed for thereby decreasing the cost, and since there is provided a lighting member, it is not needed to use the lamp. [22] 6) Since the tools attached to the chair are used for the work, the manufacturing cost is low, and the cost for purchasing the expensive dust process unit is decreased.

[32] There is further provided a spray connection tube 343 which is divided by a partition 348 at one point extended from the body 300 to the outer discharge tube 391 and is separated from the outer discharge tube 391 and communicates with the inner side of the body 300, wherein at least one fan 360 is provided in the interior of the spray connection tube 343, and a thread 345 is formed at a protruded portion of the spray connection tube 343 and is detachably engaged with the air spray unit 400.

[33] The preferred embodiment of the present invention will be described with reference to the accompanying drawings.

[34] Figure 1 is a perspective view illustrating a construction of a portable dental dust treatment device according to the present invention, and Figure 2 is a side view illustrating a construction of a portable dental dust treatment device according to the present invention.

[35] As shown in Figures 1 and 2, a dust treatment device according to the present invention comprises a head unit 100, a body 300, and a neck 200 connecting the same.

[36] The head unit 100 according to the present invention is an element used when a worker, a dentist, works an implant such as denture, etc. In a state that a denture is engaged in the interior, and a denture is washed using an air or water spraying device or is cut with other devices. The head unit 100 has a certain size so that a work can be performed on a worktable or on a dentist's knee. A head portion of the same is protruded from a neck 200 for implementing a mobility. The neck unit 200 will be described later.

[37] The head unit 100 is made of a transparent synthetic resin, preferably, made of an acryl material and is transparent so that the inner side of the same is visible from the outside. A pair of hand input parts 110 are formed at both sides of the head unit 100 so that a dentist inputs his hands. Here, the hand input part 110 is formed of a rubber band 110 extended along a circular or elliptical surface to the center potion, and a plurality of brushes 112 formed at an inner vertical side of the rubber an 110. When the dentist s hands are inputted into the interior of the head unit 100, the dusts are prevented from being spread. The hands tighten with the elastic force by the rubber band 111 are engaged with the rubber band 111. When the rubber band 111 has a too strong elastic force, the worker s hands may have pain, so that a plurality of brushes 112 are arranged in a radial shape along the center of the hand input part 110. So, even when the doctor s hands are inputted into the interior of the head unit 100, it is possible to prevent any space between the hands and the hand input parts 110. A convex lens unit 120 is provided at a front side of the head unit 100, so that a worker enlarges a certain portion. The convex lens unit 120 is positioned at a front side of the head unit 100 for thereby more efficiently being used. A lighting unit 130 is installed at one side of the inner side of the head unit 100, namely, at an inner bottom surface for supporting the lamp, with the lighting unit 130 including a socket. So, it is possible to work in a work space which is the interior of the head unit 100 without any assistance such as lighting, so that a worker can easily work.

[38] As shown in Figure 1, the lighting unit 130 may be provided at both sides for an indirect lighting effect, but it is not limited thereto. It can be installed at an upper front side of the head unit 100. The power is supplied to the lighting unit 130 by providing a battery or a power supply unit at a bottom of the head unit 100. An operation switch 170 is provided at one side of the head unit 100, so that it is possible to control the on and off of the lighting unit 130 and the intensity of light.

[39] With the head unit 100, a dentist discharges the dust producing in the course of the work to the neck 200 via the neck connection part 140. An extension end is provided at the neck connection part 140 and is protruded outward for an attachment with the neck 200. A thread 141 is formed at an outer side of the extension end and is engaged with the thread 210 formed at an end of the neck 200. A receptacle 150 is provided at the outer side of the head unit 100 for temporarily fixing and receiving an air spray unit 400 or the tools needed for the other works. So, it is possible to fix the tool to the head unity 100 in the course of work for thereby enhancing workability.

[40] The mobility of the head unit 100 is important. Casters are provided at the bottom of the same, preferably, ball casters 160 are provided. When the head unit 100 is mounted on the worktable, the head unit 100 can move properly based on the position that the worker needs with the help of the rotation of the ball caster 160.

[41] The neck 200 is a member for connecting the head unit 100 and the body 300 and has a certain length so that the head unit 100 moves within a certain range. Preferably, it is formed in a javara type made of a metal, so that a desired bending action is obtained. It is made of a synthetic material and is foldable. In the drawings, a diameter (thickness) of the neck 200 is thinner than the head unit 100 or the body 300. When it is needed to limit the moving radius of the head unit 100, it may be designed to have a diameter corresponding to the head unit 100. Threads 210 and 220 are formed at both sides of the neck 200, so that the both ends of the same are engaged with the threads 141 formed at the neck connection part 140 of the head unit 100, the threads 310a formed at the neck connection part 310 of the body 300. So, the neck 200 may be separable from the head unit 100 and the body 300.

[42] Figure 3 is a cross sectional view of the body 300 of the portable dental dust treatment device according to the present invention.

[43] The body 300 of the present invention is a key element having a unique construction and shape which are rare in the conventional dust treatment device. A main motor causing noises is removed from the conventional dust treatment device. Instead, a small motor is embedded in an impeller or a fan 360 for thereby minimizing the noises and power consumption. The body 300 separates and processes the dusts inputted from the head unit 100 via the neck 200 and supplies air to the air spray unit 400 via circulation process.

[44] A base plate 301 is provided at a lower side of the body 300 for maintaining a balance of the weight. The air supplied to the body 300 is properly distributed via the first air suction port 320 and the second air suction port 330.

[45] The dust produced in the head unit 100 is inputted into the neck connection part 310 of the body 300 via the neck 200 along with the polluted air, and a certain amount of the air is inputted into the body 300. Since the air circulation cannot be performed with the increase of air pressure, an air suction port 320, 330 is provided. With one air suction port, the air suction may lack, and the inner pressure may increase, so that two air suction portions 320 and 330 are provided. Three air suction ports may be provided. The first air suction port 320 is provided at a lower side of the body 300 and operates as a main suction port, and the second air suction port 330 is provided at one upper side of the body 330, so that it operates as an assistant air supply role of the air suction port 320. A net 332 may be provided at the first and second air suction ports 320 and 330. So, it is possible to prevent large size dusts from being inputted into the interior of the body 300. In the drawing, the next 332 is installed only at the second air suction port 330.

[46] The neck connection tube 311 extended into the interior of the neck connection part

310 and the connection tubes 321 and 331 extended into the interior of the first and second air suction ports 320 and 330 form one main connection tube 340 at a certain position. At this time, at least one fan 360 is provided for preventing a reverse flow of the air in the connection tubes 321 and 331 of the first and second air suction ports 320 and 330. The fan 360 may be provided in multiple numbers at one side of the main connection tube 340 and the spray connection tube 343.

[47] Figure 5 is a perspective view of the fan 360 of the portable dental dust treatment device according to the present invention. The fan 360 of the present invention includes a motor for thereby performing a rotation operation upon the supply of power. So, the present invention does not need a main motor provided in the conventional dust treatment device, so that the volume of the body 300 can decrease, and the power consumption and noise can decrease. The air dust treatment device is not manufactured for the dental purpose, but is designed for the use in the industrial dust treatment device. So, the volume of the motor was large. In this case, it was possible to obtain a high air pressure and an excellent dust grinding capability, but there is no problem with smaller compression air and dust grinding capability for the dental work. The fan 360 of the present invention is very inventive. The power is supplied to the fan 360 by the power supply control member (external power supply method) 317 or the battery (internal power supply method) provided in the body 300, and the rotation of the fan 360 is performed by the switch 355a provided at the operation panel 355 at one side of the body 300. The battery type may be a charging type or an exchange type. A dust filtering member 349 may be provided in the interior of the main connection tube 340 vertically with respect the extension direction of the main connection tube 340 for first filtering large size dust. The inputted dust is inputted toward the main connection tube 360 based on the rotation of the fan 360, and as shown in Figure 3, moves down at the bent portion where the main connection tube 360 is vertically bent as shown in Figure 3. The large size dusts are gathered at the dust receiving space 385 formed by the partition provided at both sides. Small size dusts and polluted air move via the purification member connection tube 341 at the upper side of the dust receiving space 385.

[48] Namely, large size dusts can be collected at the dust receiving space 385, and the dust being small and spread in the air is processed with a filtering and purification procedure. A detachable dust collection box 380 is provided at an outer side of the dust receiving space 385, namely, an outer side of the body 300. The dust collected in the dust receiving space 385 via the dust receiving box 380 is discharged to the outside. A handle 381 is provided at an outer side of the dust receiving box 380, so that a user can detach the dust receiving box 380 from the body 300.

[49] The dust moved to the purification member connection tube 341 is inputted into a small size air purification unit 390 for thereby purifying dust and polluted air. At this time, the dust can move into the dust receiving space 385 via the feed back pipe 342. The purified air moves toward the outer discharge tube 391 from the air purifier 390. With the above elements, it is possible to construct the body 300. A vertically bent spray connection tube 343 is provided at the position. A partition 348 is installed at the boundary between the spray connection tube 343 and the outer discharge tube 391 for dividing the volume of the pipe for thereby dividing the flow of air. Part of the purified air is discharged to the outside via the outer discharge pipe 391, and other part of the same moves toward the spray connection tube 343. One through three fans 360 are installed at the spray connection tube 343 for the forced movement of the air toward the spray unit 400 and the compression air formation of the air spray unit 400. The air moved to the spray connection tube 343 moves to the spray discharge port 344 formed at one side of the upper surface of the body 300. A thread 345 is formed at the protruded end of the spray discharge part 344 and is engaged with the air spray unit 400 having the thread 410 at the end. The purified air is used again in the air spray unit 400 in the course of denture work.

[50] The organic relationship between the air spray unit 400 and the body 300 is obtained, which may be needed by the doctors. So, the present invention may be adapted for various applications. The air spray unit 400 has a nozzle at the end and discharges the compressed air to the outside. When a dentist works denture work, micro dusts can be removed effectively. The air spray unit 400 may be separately stored or may be temporarily stored in the receiving parts 150 and 350 installed at the outer side of the head unit 100 or the body 300.

[51] The outer discharge tube 391 has a thread 391a at an end and is engaged with the body 300, and the length of the same can be adjusted, so that the air may be discharged to the outside or may be directly discharged in the workspace.

[52] Figure 4 is a perspective view illustrating a head unit 100 of the portable dental dust treatment device according to the present invention. Small and large size dusts can be effectively treated in the present invention. When the dust are produced less, it is not needed to operate the fan 360 of the body 300 and the air purifier 390 which need much power consumption. In this case, the dust resides in a particle state, so that it is efficient that the dust is treated by the head unit 100, not by the body 300. For this, the head unit 100 has a bent pipe 180 detachably engaged at the neck connection port 140 and a conical member 190 mounted on the bent pipe 180.

[53] As shown in Figure 4, the bent pipe 180 may be formed in an elbow shape or a S shape depending on the position and height at the portion where the neck connection part 140 is formed at the head unit 100. It is formed in an elbow shape so that the conical member 190 can be mounted on the same. An implant work is performed at the upper space of the conical member 190 for thereby discharging the dust in the conical member. The collected dusts may be discharged by inserting the hands via the hand input portion 1 lO.Figure 6 is a perspective view of another construction of the outer discharge pipe 391 of the portable dental dust treatment device according to the present invention. As shown therein, an air purifier 390 is provided at one side of the outer discharge tube 391. Since the outwardly discharged air may pollute the environment directly, it is needed to perform a second purification work of the air for preventing the pollution of air, sp that the discharge air is discharged to the outside.
