Description

UV discharge lamp device

The present invention relates to an ultraviolet discharge lamp device, and more particularly, in a simple method, an object to be treated can be inserted and arranged inside an ultraviolet lamp, and in particular, an object to be treated having various sizes can be inserted and arranged inside the ultraviolet lamp. It relates to an ultraviolet discharge lamp device.

Recently, the proportion of dental implants, which are artificial teeth, is increasing. The implant is attached to a fixture inserted into the pubis and serves as a tooth.

Typically, the dental implant structure, which is an artificial tooth, consists of three structures: Fixture (fixture-artificial tooth root), Abutment (abutment), Crown (prosthesis, artificial tooth), and titanium and titanium alloy are common as the fixture material.

In an implant procedure, the implant fixture area that is inserted into the pubis needs to be completely placed in the pubis.

To this end, as a conventional technique, when UV (ultraviolet) light is irradiated on the surface of the implant, especially the fixture, the implant surface modification phenomenon due to ozone generated by UV (ultraviolet) light energy and UV (ultraviolet) light is caused by implant placement. It is explained in detail for three reasons in detail as it promotes the proliferation and adhesion function of post-bone-forming cells to obtain excellent treatment results.

First, ozone generated by UV (ultraviolet) light energy and UV (ultraviolet) light decomposes and evaporates carbon molecules attached to the implant surface so that bone-forming cells can adhere to the implant surface well.

Second, ozone generated by UV (ultraviolet) light energy and UV (ultraviolet) light changes the surface charge of the implant from negative to positive, thereby supporting negative-charged human cells and their adhesion and function. It electrostatically attracts to the implant surface so that it can be closely bonded.

Third, if ozone generated by UV (ultraviolet) light energy and UV (ultraviolet) light increases the hydrophilicity of the implant surface, so that the blood is well wetted on the implant surface, blood clots that are well formed on the implant surface are then implanted with bone-forming cells. It helps to adhere well to the surface.

Accordingly, there is a need to provide an apparatus for easily surface-treating implants of various sizes using an ultraviolet lamp.

An embodiment of the present invention is to provide an ultraviolet discharge lamp device capable of inserting and placing an object to be treated inside an ultraviolet lamp by a simple method.

In addition, an object to be processed having various sizes is provided to provide an ultraviolet discharge lamp device capable of inserting and disposing objects into an ultraviolet lamp.

In this case, the support may include a support bar extending upward to be inserted into the object to be processed, and a support body provided under the support bar and coupled to the holder.

In this case, a ventilation groove may be formed in the support body along an axial direction so that air introduced into the discharge vessel for surface modification treatment of the object to be treated flows.

In this case, the ventilation groove may be formed to extend radially inward from the outer peripheral surface of the support body.

In this case, a support region coupled to the holder and supported in a circumferential direction may be formed on a lower surface of the support body, and the ventilation groove may extend radially inward from the support region.

In this case, the holder may include an extension wall extending upward to surround an outer circumferential surface of the support, and a holder body extending radially inward to support a lower surface of the support.

In this case, the holder body may be provided with a magnetic member so that the support body and the holder body are coupled to each other by magnetic force.

In this case, the support bar may be provided with an elastic member that presses the inner circumferential surface of the groove while the support bar is inserted into a groove formed under the object to be processed.

In this case, the elastic member may include at least two elastic bars elastically deformed outward in a radial direction, and a slit formed between the elastic bars adjacent to each other.

In this case, the support and the holder may be integrally formed.

In this case, it may further include a position adjustment unit for changing the height of the holder in the axial direction.

In this case, it may further include a post-treatment unit for reducing the concentration of ozone contained in the air discharged after the surface modification treatment of the object to be treated.

The ultraviolet discharge lamp device according to an embodiment of the present invention supports the object to be processed using a support having a simple structure, and in particular, the support bar of the support is supported by inserting it into a groove that is open in the downward direction of the object. Convenience is improved, and since the object to be treated is placed in an accurate position, the surface modification treatment effect is excellent.

In addition, since the support bar of the support is inserted from the lower side to the upper side in the groove opened in the downward direction of the object to support the object to be processed, even if the size of the object to be processed is changed, the support can be continuously used without replacing the support.

In addition, since the ventilation groove is formed on the outer circumferential surface of the support, the air introduced into the discharge vessel is smoothly discharged after the surface modification treatment, so that the surface modification treatment can be smoothly continued.

In addition, since the holder supports the outer circumferential surface and the lower surface of the support, the support can be stably coupled.

Referring to FIG. 1, the ultraviolet discharge lamp device according to an embodiment of the present invention generates UV light by a charged discharge gas, and generates ozone by the generated UV light, so that an object to be treated ( The surface modification of 10) can be performed.

At this time, in this embodiment, the object to be treated 10 is a columnar implant having a groove open in a downward direction.

Such an ultraviolet discharge lamp device may include a discharge container 100, an internal electrode 200 and an external electrode 300. Here, the discharge vessel 100 is filled with a discharge gas that generates UV light, and may have a double tube structure including an outer tube 110 and an inner tube 120. An accommodation space (S) in which the object to be processed 10 is accommodated is formed inside the inner electrode 200, and the inner electrode 200 is disposed in close contact with the inner circumferential surface of the inner tube 120, and the outer electrode 300 Is disposed in close contact with the outer circumferential surface of the outer tube 110.

Power may be supplied to the internal electrode 200 and the external electrode 300 from the outside.

Discharge gases filled in the discharge vessel 100 include Xe (wavelength 172 nm), ArF (wavelength 193 nm), KrCl (wavelength 222 nm), KrF (wavelength 248 nm), XeCl (wavelength 308 nm), and XeF (wavelength 351 nm). A discharge gas that generates excimer UV light may be used, but a material capable of generating ultraviolet rays in the UVC wavelength band (100 nm to 280 nm) may be used.

In addition, as shown in FIG. 2, the internal electrodes 200 may be provided in a pair on both sides of the hollow part 140 of the discharge container 100. The internal electrode 200 may have a cylindrical shape having a hollow portion 220.

In this case, a void 200c may be formed between the first internal electrode 200a and the second internal electrode 200b so that the object 10 is disposed. That is, the first internal electrode 200a and the second internal electrode 200b may be separated at a predetermined interval so that the object 10 is disposed in the gap 200c therebetween.

Here, the UV light generated by the discharge gas filled in the discharge container 100 passes through the gap 200c between the pair of

internal electrodes

200a and 200b to the inside of the hollow part 140 of the discharge container 100. Is radiated.

Accordingly, the UV light generated in the gas filling region 130 is not blocked by the internal electrode 200 and is directly radiated to the hollow part 140 of the discharge vessel 100, so that the object 10 is uniformly irradiated. Can be. In addition, a larger amount of UV light may be irradiated compared to the case where the internal electrode 200 exists around the object 10. Accordingly, the surface modification of the object 10 is uniformly performed, and the surface modification treatment time can be drastically shortened.

Here, the power supply line 210 may be connected to the internal electrode 200 so that power can be supplied from the outside. Each of the first internal electrode 200a and the second internal electrode 200b may be connected to the power supply line 210.

Alternatively, the internal electrode 200 may be integrally formed. In this case, the internal electrode 200 may have a plurality of light-transmitting portions formed in a mesh shape, a grid pattern shape, or the like. UV light generated in the gas filling region 130 may be radiated into the inner electrode 200 through the light transmitting part.

The external electrode 300 is provided along the outer circumferential surface of the outer tube 110 of the discharge container 100, and the external electrode 300 may have a cylindrical structure having a hollow portion 310.

Here, the external electrode 300 functions to reflect UV light generated by the discharge gas in the gas filling region 130 to the inside of the hollow portion 140 of the discharge container 100. In this case, the external electrode 300 may be mirror-treated to reflect UV light.

In addition, the external electrode 300 may have a thin foil shape or a mesh shape. However, the present invention is not limited thereto, and the external electrode 300 may be used regardless of its shape as long as it is a conductive material for causing discharge.

The external electrode 300 may further include a heat sink for cooling the discharge container 100. Here, the heat sink may be provided outside the external electrode 300. For example, the heat sink may have a cylindrical structure surrounding the external electrode 300. Optionally, the heat sink may include a protruding structure to increase the surface area for effective cooling.

Air may be introduced into the upper side of the discharge vessel 100, and since oxygen (O2) is included in the introduced air, oxygen in the air is changed to ozone (O3) by UV light of the discharge vessel 100.

As shown in FIG. 1, a fan 900 is provided so that air is introduced into the discharge container 100 and ozone generated in the discharge container 100 is discharged to the outside of the discharge container 100. do.

As an example, the fan 900 may be driven at a low speed when ozone is generated in the discharge container 100, so that air may be introduced from the upper side of the discharge container 100. That is, the fan 900 may be driven at a low speed while the object 10 is surface-modified.

In addition, the fan 900 is driven at high speed when ozone generated in the ultraviolet discharge container 100 is discharged, so that the fluid flow path 710 from the air flow port 530 of the holder 500 provided at the lower side of the discharge container 100 Ozone may be discharged to the outside of the discharge container 100 through the 910. That is, the fan 900 may be driven at high speed after surface modification treatment of the object 10 to be processed.

In addition, as shown in FIG. 1, the ultraviolet discharge lamp device may further include a filter 800. The filter 800 may be connected between the discharge container 100 and the fan 900 through

fluid flow paths

710 and 910. Here, the filter 800 may remove ozone discharged from the discharge container 100.

For example, the filter 800 may be a carbon filter. As another example, the filter 800 may include an ozone adsorbent such as activated carbon. Accordingly, the fan 900 may discharge oxygen from which ozone is removed from the discharge container 100 to the outside.

In the ultraviolet discharge lamp device, as shown in FIG. 1, the support 400 on which the object to be processed 10 is supported, and the support 400 are arranged in the receiving space S. Includes a holder 500.

According to an embodiment of the present invention, since the support 400 of a simple structure is used to support the object to be processed 10 of various sizes, operation convenience is improved.

The holder 500 is for placing the object 10 in the discharge vessel 100, and supports the object 10 to be positioned in the void 200c between the pair of

internal electrodes

200a and 200b. Can support 400.

In this case, the holder 500 may be inserted into the inner side of the pair of

internal electrodes

200a and 200b to be coupled in a state capable of reciprocating movement in the insertion direction. That is, the holder 500 may move upward from the inner side of the pair of

inner electrodes

200a and 200b to expose the upper end to the upper side of the coupling structure of the inner electrode 200, the discharge vessel 100, and the outer electrode 300. have.

In addition, the holder 500 is coupled to the support 400 on which the object 10 is supported on the exposed upper end, and moves downward while the object 10 is supported by the support 400 to 10 may be introduced into the hollow part 220 of the internal electrode 200.

In addition, the holder 500 may be made of a material that does not affect the surface material of the object 10. For example, the holder 500 may be made of a ceramic material so as not to react with UV light emitted from the gas filling region 130 and ozone generated by the UV light.

In addition, the holder 500 may include an air flow port 530 through which air is introduced and discharged along the axial direction in the center. Here, the air flow port 530 may allow air introduced into the discharge vessel 100 to flow.

Thereby, the ozone generation concentration can be adjusted so that ozone generated by UV light irradiation is limited to the periphery of the object 10, that is, in a required space.

Optionally, the holder 500 may rotate inside the pair of

internal electrodes

200a and 200b. Here, the holder 500 may be controlled by the controller 1000 to rotate, rise and fall.

In this case, as shown in FIG. 3, the support 400 is provided under the support bar 410 extending upward to be inserted into the object to be processed 10 and the support bar 410 is coupled to the holder 500 It may include a supporting body (420).

The support 400 is for supporting the object 10 to be processed, and to place the object 10 in the receiving space S inside the discharge container 100.

This support 400 may be coupled to the upper portion of the holder 500.

As described above, the support 400 is provided with a support bar 410 extending upward to support the object 10 in a simple manner that is inserted into a groove open in the downward direction of the object 10 Workability is improved, and since the support 400 does not cover the outside of the object to be treated 10, the exposed area is maximized, thereby increasing the efficiency of the surface modification treatment by the air introduced into the discharge container 100.

Alternatively, the support 400 and the holder 500 may be integrally formed.

In addition, since the support bar 410 of the support 400 is supported by inserting it into a groove formed under the object 10, even if the size of the object 10 is changed, the support 400 is not replaced. It becomes possible to continue to use it without. In this case, the diameter of the support bar 410 may be smaller than the size of the groove of the object 10, and the length of the support bar 410 is preferably formed longer than the depth of the groove. The object to be treated 10 may or may not be fixed to the support bar 410 in a state coupled to the support bar 410.

At this time, as shown in Figs. 4 and 5, various types of objects 10 having different inner diameters or depths of the grooves may be supported by the support 400, as described above, It is used by inserting the support bar 410 of the support 400 into a groove formed under the water 10.

The support body 420 is formed under the support bar 410 so that it can be stably coupled and fixed to the holder 500 even during the surface modification process.

A ventilation groove 421 is formed in the support body 420 along the axial direction so that air introduced into the discharge container 100 flows for surface modification treatment of the object 10.

That is, the surrounding air of the object 10 supported by the support bar 410 flows through the ventilation groove 421 and flows out of the discharge vessel 100 after the surface modification treatment, and thereafter, the air flow port 530 Flows toward.

The ventilation grooves 421 may be formed to extend radially inward from the outer circumferential surface of the support body 420, and may be formed in plural along the circumference of the outer circumferential surface of the support body 420.

At this time, as shown in FIG. 6, a support region 422 coupled to the holder 500 along the circumferential direction is formed on the lower surface of the support body 420, and the ventilation groove 421 is the support region 422. The open area 421a may be formed while extending inward in the radial direction. That is, the open area 421a is formed to extend radially inward than the inner circumferential surface of the holder body 520 to be described later.

That is, as described above, the support body 420 is coupled to the upper portion of the holder 500. Even when the support body 420 is coupled to the holder 500, a ventilation groove formed in the support body 420 ( 421) needs to be configured so that air flows smoothly.

To this end, a support region 422 coupled to the holder 500 and supported by the holder 500 is formed on the lower surface of the support body 420, as well as an open region 421a extending radially inward from the support region 422 to form a discharge container. (100) Since the air introduced into the interior is smoothly outflowed after the surface modification treatment, the surface modification treatment can be smoothly continued.

In addition, as shown in FIG. 1, the holder 500 includes an extension wall 510 extending upward to surround the outer circumferential surface of the support 400, and a holder extending radially inward to support the lower surface of the support 400. The body 520 may be included, and when configured in this way, the holder 500 supports the circumferential outer circumferential surface and the lower surface of the support 400 so that the support 400 can be stably coupled.

The support 400 is coupled in a manner that moves downward along the inner circumferential surface of the extension wall 510 of the holder 500, and when the lower surface of the support 400 is seated on the upper surface of the holder body 520, the coupling process is completed.

At this time, it is also possible to fix the outer circumferential surface of the support 400 to the inner circumferential surface of the extension wall 510 by pressing, but as shown in FIG. 7, the support body 420 and the holder body 520 It is also possible that the magnetic member 521 is provided on the holder body 520 so as to be coupled to each other.

This is because the support 400 can be stably coupled by the magnetic member 521 even if the outer circumferential surface of the support 400 and the inner circumferential surface of the extension wall 510 are separated by a predetermined distance.

In this case, as shown in FIG. 8, the support bar 410 includes an elastic member 411 that presses the inner circumferential surface of the groove while the support bar 410 is inserted into the groove formed under the object 10. It can be provided. As such, the elastic member 411 is provided so that the object 10 can be stably fixed, and the object 10 is not shaken even in the working process, thereby improving the surface modification treatment efficiency.

The elastic member 411 may include at least two elastic bars 411a elastically deformed outward in the radial direction, and a slit 411b formed between the elastic bars 411a adjacent to each other.

That is, the elastic bar (411a) is manufactured in a state that is elastically deformed to the outside of the radial reflection during manufacture, and the support bar in the groove of the object to be treated 10 while the elastic member 411 is installed on the support bar (410). When the 410 is inserted, the elastic bar 411a is elastically deformed to press the inner circumferential surface of the groove.

It is preferable that at least two of these elastic bars 411a are provided to uniformly press the circumference of the inner circumferential surface of the groove. It is also possible to have only (411a).

In addition, a slit (411b) is formed between the mutually adjacent elastic bars (411a) to be spaced apart from each other, and such a slit (411b) is provided so that the mutually adjacent elastic bars (411a) interfere with each other in the process of elastic deformation. This does not occur, and elastic deformation becomes possible effectively.

At this time, it may further include a position adjustment unit 600 for changing the axial height of the holder 500. The position adjustment unit 600 changes the height of the holder 500 to move the support 400 to a position for surface modification treatment of the object 10, or the object 10 for which the surface modification treatment is completed. It is possible to move the support 400 to take out.

The height change of the holder 500 through the position adjustment unit 600 may be automatically performed by the control unit 1000, and through this, the input or collection of the object 10 can be conveniently performed.

In addition, it may further include a post-treatment unit 700 for reducing the concentration of ozone contained in the air discharged after the surface modification treatment of the object 10.

The post-treatment unit 700 thermally decomposes ozone so that the concentration of ozone contained in the outflow air is 0.05 ppm or less. At this time, the post-treatment unit 700 may pyrolyze ozone at a temperature of 200 to 900°C. Here, the pyrolyzed ozone is converted into oxygen (O2). A heating source is provided in the post-treatment unit 700, and the heating source is for thermally decomposing ozone and may generate heat at a temperature of 200 to 900°C. As an example, the heating source may include a halogen lamp. Since such a halogen lamp has a low power consumption, a heating source can be implemented at a low cost, and its temperature rise time is shorter than that of a general heater, so it has excellent thermal efficiency.

As another example, the heating source may include a ceramic heater.

In addition, the post-treatment unit 700 is provided with a cooling member to cool the discharged air. That is, air and oxygen cannot be discharged as they are because they are in a high temperature state due to thermal decomposition of ozone, so they are cooled to a relatively low temperature and then discharged.

Although an embodiment of the present invention has been described, the spirit of the present invention is not limited to the embodiments presented in the present specification, and those skilled in the art who understand the spirit of the present invention add or change components within the scope of the same idea. Other embodiments may be easily proposed by deletion, addition, and the like, but it will be said that this is also within the scope of the present invention.
