Description

Technical Field

[0001] This utility model relates to the field of carving knife technology, and in particular to a multifunctional special ceramic carving knife. Background Technology

[0002] Special ceramics are a class of inorganic non-metallic materials with special physical, chemical or mechanical properties. Special ceramics are usually carved with carving tools during the production process, mainly to meet the needs of precision processing, functional customization or artistic creation.

[0003] Ceramic carving knives mainly consist of a blade, a handle, and a tip. They are used for carving, cutting, or finishing ceramics. They are characterized by their sharpness, wear resistance, and corrosion resistance. When carving by hand, you first need to draw a pattern on the ceramic surface and fix the workpiece. Then, use the tip of the knife to carve the outline along the lines, gradually deepen the details and clean up the debris. Finally, you finish and polish. This method relies on the craftsman's skill and allows for precise control of force and angle. It is suitable for creating personalized ceramic artworks or for small-batch fine processing.

[0004] Current ceramic carving operations typically involve sculptors using carving knives to carve the fired ceramic body. However, because the fired ceramic body is dry and brittle, the local stress acting on the edge of the carving groove under the cutting action of the carving tool is very easy to concentrate and exceed the tolerance limit of the ceramic material, resulting in uncontrollable chipping at the edge of the carving groove. This chipping problem not only directly damages the fineness and integrity of the carved pattern, but also seriously affects the processing accuracy and finished product qualification rate of special ceramic products. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the drying of the ceramic body during the carving process can cause cracks at the edge of the carving groove, and to propose a multifunctional special ceramic carving knife.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional special ceramic carving knife includes a pen tip and a hollow handle detachably mounted on the pen tip. The pen tip has a blade fixedly mounted at its end, and the blade has a chip removal pit and a chip removal groove. It also includes a water-absorbing strip fixedly mounted on the blade. The blade has a positioning groove and a drain hole. The water inlet of the drain hole extends into the pen tip, and a connecting hole communicates with the drain hole. The water-absorbing strip contacts the drain hole through the positioning groove. When liquid flows out of the drain hole, the water-absorbing strip absorbs the liquid. A water storage device is provided inside the handle for storing liquid.

[0008] To maintain the wetness of the absorbent strip, preferably, the water storage component includes a liquid storage bladder that is detachably installed on the pen tip. The outlet of the liquid storage bladder is connected to the inlet of the drain hole. A sealing sheet is slidably installed inside the liquid storage bladder. A limiting protrusion ring is provided inside the liquid storage bladder corresponding to the sealing sheet. The sealing sheet divides the liquid storage bladder into a water storage area and a pressure area. A pressing part is provided in the pressure area. When the pressing part is pressed, the sealing sheet is pressed and moves to push the liquid out.

[0009] To facilitate control of the humidity of the absorbent strip, the pressing part further includes a pressing button that is slidably installed on the pressing end of the handle. The bottom end of the pressing button extends to the pressure area, and the cylindrical surface of the pressing button is in contact with the inner wall of the pressure area. A spring is fixedly installed in the pressure area, and the two ends of the spring abut against the bottom surface of the pressing button and the limiting protrusion ring, respectively.

[0010] To prevent the sealing sheet from being sucked up when the button is reset, a pressure equalization hole is further provided on the cylindrical surface of the pressure zone. A one-way gasket is rotatably installed in the pressure equalization hole, and a protrusion is provided in the through hole, with the air inlet end face of the one-way gasket in contact with the protrusion.

[0011] To facilitate air entry into the pressure zone, the ratio of the outer diameter of the reservoir to the inner diameter of the handle is 6:5, and a ventilation zone is formed between the reservoir and the handle. The pressure zone and the ventilation zone are connected through a pressure equalization hole.

[0012] To prevent ceramic chips from absorbing water and sticking to the cutter head, the chip removal pit is preferably set as a semi-circle, and the diameter of the chip removal pit is in the range of 0.1mm-0.3mm.

[0013] To facilitate water filling into the reservoir, preferably, the reservoir has a water inlet hole on its end face, and an anti-overflow pad is movably installed inside the water inlet hole.

[0014] To prevent the carving knife from slipping out of the hand, preferably, an anti-slip pad is fixedly installed on the gripping surface of the handle, and the surface of the anti-slip pad is provided with hemispherical protrusions arranged in a ring.

[0015] To maintain the rigidity of the cutting head, preferably, the volume ratio of the cutting head to the drainage hole is 5:2.

[0016] To facilitate the removal of ceramic debris, preferably, the depth of the chip removal groove is 1mm-2mm, and the angle between the chip removal groove and the engraving edge of the cutter head is 50°-60°.

[0017] Compared with the prior art, this utility model provides a multifunctional special ceramic engraving knife, which has the following beneficial effects:

[0018] 1. This multi-functional special ceramic carving knife, through the combined use of a drain hole and a water-absorbing strip, keeps the water-absorbing strip moist. When carving special ceramics, the knife head contacts the ceramic carving surface to wet the ceramic, making it easier for the knife head to carve the ceramic carving area. This avoids the problem of the carving groove edge cracking due to the dryness of the ceramic body, effectively improving the fineness and integrity of the carved pattern, and improving the processing accuracy and finished product qualification rate of special ceramic products.

[0019] 2. This multi-functional special ceramic carving knife uses a combination of chip removal grooves and chip removal pits. On the one hand, the chip removal pits reduce the contact area between ceramic chips and the knife head, thus preventing the wet ceramic from sticking to the carving edge of the knife head. On the other hand, the carved ceramic chips are discharged to the sides of the ceramic carving groove through the chip removal grooves, avoiding the problem of wet ceramic chips remaining in the carving groove and sticking to the ceramic again.

[0020] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model utilizes a drainage tank and a wetting strip in combination. The wetting strip maintains humidity, and the ceramic absorbs water and becomes moist after contact, thus facilitating carving and avoiding chipping problems caused by excessive dryness of the ceramic.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example:

[0030] Reference Figures 1-5A multifunctional special ceramic carving knife includes a pen tip 1 and a hollow handle 2 detachably mounted on the pen tip 1. A cutting head 3 is fixedly mounted on the end of the pen tip 1. The cutting head 3 has a chip removal pit 31 and a chip removal groove 32. The chip removal pit 31 is semi-circular, and its diameter ranges from 0.1mm to 0.3mm. In this application, the chip removal pit 31 preferably has a diameter of 0.1mm. This reduces the contact area between carving chips and the cutting head 3 and prevents chips from entering the chip removal pit 31 with a larger diameter. To address the issue of clogging and effectively prevent debris from adhering to the cutting head 3, a water-absorbing strip 5 is fixedly installed on the cutting head 3. The water-absorbing strip 5 is made of porous ceramic, utilizing micropores on its surface to create capillary action. This allows it to absorb water while maintaining its own moisture level, facilitating water absorption during ceramic carving and preventing cracking caused by dry carving. The depth of the chip removal groove 32 ranges from 1mm to 2mm, and the angle between the chip removal groove 32 and the carving edge of the cutting head 3 ranges from 50° to 60°. This application's chip removal groove... The preferred depth of the chip removal groove 32 is 1mm. This maintains the rigidity of the chip removal groove 3, preventing deformation during use, and effectively removes ceramic carving debris. The preferred included angle range is 50°. The inclined chip removal groove 32 facilitates the removal of debris from the carving groove, preventing secondary adhesion between debris and ceramic, thus improving the carving effect. The chip removal groove 32 has a positioning groove 4 and a drain hole 6, with the inlet end of the drain hole 6 extending to the pen. Inside the head 1, the connecting hole is connected to the drain hole 6. The absorbent strip 5 contacts the drain hole 6 through the positioning groove 4. When liquid flows out of the drain hole 6, the absorbent strip 5 absorbs the liquid, thereby maintaining its own humidity. This makes it easy to moisten the carving area when carving ceramics. The handle 2 is equipped with a water storage device to store liquid in the handle 2. The user can drain the liquid in the water storage device according to the degree of moisture of the absorbent strip 5, thereby maintaining the moisture of the absorbent strip 5 and making it easy for the ceramic carving area to absorb water, avoiding the situation of cracking during carving due to excessive dryness.

[0031] Specifically, the combined use of the drain hole 6 and the absorbent strip 5 keeps the absorbent strip 5 moist. When carving special ceramics, the cutter head 3 wets the ceramic carving surface, making it easier for the cutter head 3 to carve the carving area of ​​the ceramic. This avoids the problem of the carving groove edge cracking due to the dryness of the ceramic body, effectively improving the fineness and integrity of the carved pattern, and improving the processing accuracy and finished product qualification rate of special ceramic products. The chip removal groove 32 and chip removal pit 31 work together to reduce the contact area between ceramic chips and the cutter head 3, thereby preventing the wet ceramic from sticking to the carving edge of the cutter head 3. On the other hand, the carved ceramic chips are discharged to the sides of the ceramic carving groove through the chip removal groove 32, avoiding the problem of wet ceramic chips remaining in the carving groove and sticking to the ceramic again.

[0032] The water storage component includes a liquid storage bladder 7 detachably mounted on the pen tip 1. The outlet of the liquid storage bladder 7 is connected to the inlet of the drain hole 6. A sealing plate 8 is slidably installed inside the liquid storage bladder 7. A limiting protrusion ring is provided inside the liquid storage bladder 7 corresponding to the sealing plate 8. A rubber ring is provided on the edge of the sealing plate 8 to keep the liquid storage bladder 7 and the sealing plate 8 sealed, preventing the liquid in the liquid storage bladder 7 from flowing out due to gravity. The sealing plate 8 divides the liquid storage bladder 7 into a water storage area and a pressure area. A pressing part is provided in the pressure area. When the pressing part is pressed, the sealing plate 8 is pressed and moves to push the liquid out, thereby draining the liquid into the drain hole 6, which is convenient for the absorbent strip 5 to absorb and keep the absorbent strip 5 moist, making it convenient for the user to carve ceramics.

[0033] The pressing part includes a pressing button 10 slidably mounted on the pressing end of the handle 2. The bottom end of the pressing button 10 extends to the pressure zone. The cylindrical surface of the pressing button 10 is in contact with the inner wall of the pressure zone. A spring 9 is fixedly installed in the pressure zone. The two ends of the spring 9 abut against the bottom surface of the pressing button 10 and the limiting protrusion ring, respectively. A pressure equalization hole is opened on the cylindrical surface of the pressure zone. A one-way gasket is rotatably installed in the pressure equalization hole. A protrusion is provided in the through hole, and the air inlet end face of the one-way gasket contacts the protrusion. The ratio of the outer diameter of the reservoir 7 to the inner diameter of the handle 2 is 6:5, and a ventilation zone is formed between the reservoir 7 and the handle 2. The pressure zone and the ventilation zone are connected through the pressure equalization hole. When the button 10 is pressed, the pressure zone is pressurized and then the pressure is transmitted to the sealing plate 8. The sealing plate 8 moves down and pushes the liquid out through the drain hole 6, which helps to maintain the wetness of the absorbent strip 5. At the same time, when the button 10 is released, the spring 9 deforms and rebounds, pushing the button 10 back to its original position. At this time, a negative pressure is formed in the pressure chamber. The one-way pad rotates along the shaft to open the pressure equalization hole and allow the gas in the ventilation zone to enter the pressure zone, thereby maintaining the pressure balance between the pressure zone and the liquid storage zone. This effectively prevents the sealing plate 8 from moving due to the negative pressure, which would cause the liquid to be sucked into the liquid storage bladder 7, resulting in the interruption of the water supply to the absorbent strip 5 and thus reducing the wetness of the absorbent strip 5.

[0034] The end face of the reservoir 7 is provided with a water inlet, and an anti-overflow pad is movably installed inside the water inlet. When the liquid inside the reservoir 7 is used up, the handle 2 and the reservoir 7 are disassembled, the anti-overflow pad is removed, and then the liquid is injected into the reservoir 7 through the water inlet, so that the reservoir 7 can be recycled. The water inlet is used in conjunction with the water outlet of the reservoir 7 to facilitate the injection of liquid into the reservoir 7 and avoid the problem that the liquid is difficult to inject into the reservoir 7 due to atmospheric pressure.

[0035] An anti-slip pad 11 is fixedly installed on the grip surface of the handle 2. The surface of the anti-slip pad 11 is provided with hemispherical protrusions arranged in a ring. The anti-slip pad 11 on the handle 2 effectively improves the user's hand feel when carving, and at the same time avoids the problem of the carving knife slipping out of the hand and damaging the ceramic carving area during the carving process.

[0036] The volume ratio of the cutter head 3 to the drain hole 6 is 5:2. By making the drain hole 6 occupy a smaller volume of the cutter head 3, the rigidity of the cutter head 3 is maintained, and the problem of deformation during use is avoided, thereby extending the service life of the cutter head 3.

[0037] In this invention, firstly, the pressing button 10 is pushed, causing it to move downwards and compress the air in the pressure zone. At this time, the pressure in the pressure zone is transmitted to the sealing plate 8, which moves downwards under force and compresses the liquid in the storage zone. Subsequently, the liquid outlet 6 in the storage zone comes into contact with the absorbent strip 5. The absorbent strip 5 absorbs water and becomes wet. Then, the handle 2 is gripped and the ceramic is carved. When the cutting head 3 contacts the ceramic, the absorbent strip 5 also contacts the ceramic. The ceramic absorbs water, reducing its dryness, thus facilitating carving by the cutting head 3 and preventing damage to the ceramic body. Dryness can cause the edge of the carving groove to crack during carving. If the moisture content of the absorbent strip 5 decreases, push the button 10 again and repeat the above operation. When the button 10 is released, the spring 9 deforms after the force decreases, pushing the button 10 to reset. At this time, a negative pressure is formed in the pressure zone, causing the one-way gasket to rotate along the axis of the rotating shaft and open the pressure equalization hole. At this time, due to the pressure difference between the ventilation zone and the negative pressure zone, the gas in the ventilation zone enters the pressure zone, thereby maintaining the pressure of the pressure zone and the liquid storage zone consistent, and avoiding the problem of the sealing plate 8 absorbing the water in the liquid storage zone after moving up due to the negative pressure.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
