Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, and in particular to a dust-free hole opener for drilling holes in ceramic tiles. Background Technology

[0002] Tiles are a type of rigid non-metallic material widely used in building decoration, possessing excellent properties such as wear resistance, water resistance, and ease of cleaning. In home renovations, public space construction, and various building projects, tiles are commonly used for wall and floor paving to enhance overall aesthetics and hygiene. With the diversification of modern decoration needs, tile installation often requires drilling holes to facilitate pipe installation, wiring, and hardware installation. Therefore, tile drilling is a crucial step in the construction process, and its efficiency and quality directly affect the overall decoration effect and construction safety.

[0003] Existing technologies, such as the utility model patent with publication number CN213860055U, disclose a dust-free hole drill for drilling holes in ceramic tiles. This drill includes a mounting base, drill shank, center drill, cover, cutting head, sponge, and fastening bolts. It achieves dust reduction or a dust-free effect by using a sponge within the cover to absorb dust generated during the drilling process. This device is simple in structure, low in cost, and has some practicality. However, in actual use, the inventors discovered a serious drawback: because it uses a fixed-position sponge as the main dust-reducing component, its dust-absorbing capacity is limited. Furthermore, during continuous high-speed drilling, the sponge easily becomes saturated quickly, losing its dust-reducing function, leading to a large amount of dust overflowing, polluting the construction site, and potentially endangering the respiratory health of operators.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a dust-free hole cutter for tile drilling. This new type of hole cutter should retain its original portability and economy while incorporating reusable, high-efficiency dust suppression components or a water mist dust suppression system. This would achieve continuous, stable, and efficient dust control, avoiding frequent replacement of consumables, thereby significantly improving the environmental friendliness and work efficiency of tile drilling operations. It would better meet the development needs of modern green construction and humanized working environments, providing strong support for the sustainable development of the building decoration industry. Utility Model Content

[0005] The purpose of this invention is to provide a dust-free hole punch for drilling holes in ceramic tiles. This invention solves the problems of existing technologies that use fixed-position sponges as the main dust-reducing components, which have limited dust-collecting capacity and are prone to rapid saturation and loss of dust-reducing function during continuous high-speed drilling, resulting in a large amount of dust overflowing, polluting the construction site, and potentially endangering the respiratory health of operators.

[0006] To achieve the above objectives, this utility model provides a dust-free hole opener for drilling holes in ceramic tiles, including a cutting tool and a drill shank connected to the center of the top of the cutting tool;

[0007] The outer ring of the cutter is rotatably connected to a mounting ring plate via a rotating component. A gripping assembly is provided on one side of the mounting ring plate, a liquid delivery assembly is provided on the top of the mounting ring plate, and several spray dust suppression structures are provided at the bottom of the mounting ring plate. The liquid delivery assembly and the several spray dust suppression structures are interconnected.

[0008] The mounting ring plate has a mounting groove on its top. The liquid delivery assembly includes a liquid distribution pipe and a liquid delivery pipe. The liquid distribution pipe is connected inside the mounting groove. One end of the liquid delivery pipe is connected to the liquid distribution pipe, and the other end is used to connect to a water source.

[0009] The rotating component includes an outer ring that is fixedly connected to the outer ring of the tool by a mounting ring bolt, and a rotating groove is provided at the center of the outer ring.

[0010] The grip assembly includes a handle connected to one side of the mounting ring plate via a connecting plate, and the outer ring of the handle has several anti-slip grooves.

[0011] The inner ring of the mounting ring plate is connected to a rotating ring that is adapted to rotate the rotating groove, and the side wall of the mounting ring is provided with a number of mounting holes.

[0012] The dust suppression spraying structure includes a spray pipe and a nozzle. One end of the spray pipe is connected to the nozzle, and the other end is connected to the distribution pipe.

[0013] This utility model discloses a dust-free hole cutter for drilling holes in ceramic tiles. By setting up a spray dust suppression structure to replace the traditional sponge adsorption method, it fundamentally solves the problems of limited dust absorption capacity and easy saturation and failure of sponges, achieving continuous and efficient dust control, significantly reducing the dust concentration at the construction site, improving the working environment, and ensuring the health and safety of construction personnel. Secondly, the spray system adopts the principle of liquid dust suppression, which can effectively cool the blade and lubricate the cutting surface, reduce blade wear caused by high temperature or friction, extend the tool's service life, and improve the drilling accuracy and flatness.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Example 1

[0023] Please see Figure 1-5 As shown, a dust-free hole opener for drilling holes in ceramic tiles according to this embodiment includes a cutter 3 and a drill shank 1 connected to the center of the top of the cutter 3;

[0024] The top of the outer ring of the cutter 3 is rotatably connected to the mounting ring plate 2 via a rotating component. A gripping component is provided on one side of the mounting ring plate 2, a liquid delivery component is provided on the top of the mounting ring plate 2, and several spray dust suppression structures are provided at the bottom of the mounting ring plate 2. The liquid delivery component and the several spray dust suppression structures are interconnected.

[0025] The operator first secures the device using the gripping assembly on one side of the mounting ring 2, and aligns the cutter 3 with the surface of the tile to be drilled. Then, the electric drill drives the drill shank 1, causing the cutter 3 to rotate at high speed and cut the tile. Simultaneously, the liquid delivery assembly at the top of the mounting ring 2 begins supplying liquid to several spray dust suppression structures evenly distributed around the cutter 3. During the drilling process, these structures continuously spray water mist into the drilling area, wetting and settling dust particles at their initial formation, effectively suppressing dust diffusion. Because a stable fluid channel is formed between the spray dust suppression structures and the liquid delivery assembly, the entire dust suppression process can be run continuously without the need to replace consumables midway, greatly improving dust suppression efficiency and operational stability.

[0026] Example 2

[0027] Please see Figure 1-5 As shown in the figure, this embodiment of a dust-free hole drill for drilling holes in ceramic tiles has a mounting groove 8 on the top of the mounting ring plate 2. The liquid delivery component includes a distributing pipe 7 and a delivery pipe 9. The distributing pipe 7 is connected inside the mounting groove 8, and one end of the delivery pipe 9 is connected to the distributing pipe 7, while the other end is connected to a water source. Specifically, through the mounting groove 8, distributing pipe 7, and delivery pipe 9 on the top of the mounting ring plate 2, a complete fluid delivery system is formed between the liquid delivery component and the dust suppression spray structure. One end of the delivery pipe 9 is connected to a water source, and the other end is connected to the distributing pipe 7, ensuring that the liquid can be evenly distributed to each dust suppression spray structure. During the drilling process, water mist is continuously sprayed onto the drilling area, so that the dust is moistened and settled at the beginning of its generation, thereby effectively inhibiting the spread of dust and achieving continuous operation without the need to replace consumables midway, greatly improving dust suppression efficiency and operational stability.

[0028] The grip assembly includes a handle 10 connected to one side of the mounting ring plate 2 via a connecting plate 11. The outer circumference of the handle 10 has several anti-slip grooves. Specifically, through the design of the handle 10 and connecting plate 11, the handle 10 has several anti-slip grooves, providing better grip and control. This not only increases operational safety but also improves operational comfort during extended work periods, ultimately enhancing the operator's experience and work efficiency.

[0029] The spray dust suppression structure includes a spray pipe 5 and a nozzle 4. One end of the spray pipe 5 is connected to the nozzle 4, and the other end is connected to a distribution pipe 7. Specifically, through the arrangement of the spray pipe 5 and nozzle 4, with one end of the spray pipe 5 connected to the nozzle 4 and the other end connected to the distribution pipe 7, it is ensured that the water mist can accurately cover the drilling area, effectively suppressing the spread of dust. This design not only improves dust suppression efficiency but also avoids the frequent replacement problems associated with traditional sponge adsorption methods, achieving a more environmentally friendly and efficient construction effect. It also improves the working environment and ensures the health and safety of operators.

[0030] Example 3

[0031] Please see Figure 1-5 As shown in this embodiment, a dust-free hole saw for drilling holes in ceramic tiles includes a rotating component comprising an outer ring 13 fixedly connected to the outer ring of a cutter 3 by a mounting ring 6 bolt. A rotating groove 14 is formed at the center of the outer ring 13. Specifically, the flexible rotational connection between the cutter 3 and the mounting ring 2 is achieved through the outer ring 13 and its rotating groove 14, and the rotating ring 12 connected to the inner ring of the mounting ring plate 2. This design allows the operator to adjust the angle of the cutter as needed to adapt to different drilling requirements, while ensuring the stability and flexibility of the equipment during use, thus improving operational comfort and drilling accuracy.

[0032] The inner ring of the mounting ring plate 2 is connected to a rotating ring 12 that is adapted to rotate within the rotating groove 14. Several mounting holes are provided on the side wall of the mounting ring 6. Specifically, the rotational adaptation between the rotating ring 12 connected to the inner ring of the mounting ring plate 2 and the rotating groove 14, along with the mounting holes on the side wall of the mounting ring 6, further enhances the overall stability and durability of the device. This structural design allows for smooth rotation between the mounting ring plate 2 and the cutter 3, reducing friction and wear, thus extending the equipment's service life and maintaining long-term high-efficiency performance.

[0033] In a dust-free hole cutter for drilling holes in tiles, the complete workflow is as follows: The operator first securely holds the device using a grip assembly, which includes a handle 10 connected to one side of the mounting ring plate 2 and fixedly connected via a connecting plate 11. The handle 10 has several anti-slip grooves on its outer circumference to enhance grip and improve operating comfort. Then, the cutter 3 is aligned with the tile surface to be drilled, and the drill shank 1 is driven by an electric drill to rotate the cutter 3 at high speed, initiating the cutting operation. Simultaneously, the liquid delivery assembly begins operation. This assembly includes a distribution pipe 7 and a delivery pipe 9 located at the top of the mounting ring plate 2. The distribution pipe 7 is installed in a mounting groove 8 at the top of the mounting ring plate 2. One end of the delivery pipe 9 is connected to the distribution pipe 7, and the other end is connected to an external water source. Liquid is delivered through the delivery pipe 9 to the distribution pipe 7 and then distributed to multiple spray dust suppression structures.

[0034] The spray dust suppression structure includes a spray pipe 5 and a nozzle 4. One end of the spray pipe 5 is connected to the nozzle 4, and the other end is connected to the distribution pipe 7. During the drilling process, water mist is continuously sprayed into the drilling area, causing dust to be moistened and settled at the initial stage of generation, thereby effectively inhibiting dust diffusion and achieving the purpose of dust-free or low-dust operation. Because a stable fluid channel is formed between the spray dust suppression structure and the liquid delivery component, the entire dust suppression process can be continuously operated without the need to replace consumables midway, greatly improving dust suppression efficiency and operational stability.

[0035] The rotating component consists of an outer ring 13, a rotating groove 14, a rotating ring 12, and a mounting ring 6. The outer ring 13 is bolted to the outer ring of the tool 3 via mounting holes on the mounting ring 6. The outer ring 13 has a rotating groove 14 at its center, while the inner ring of the mounting ring plate 2 has a rotating ring 12 that matches the rotating groove 14. This structural design enables a flexible rotating connection between the tool 3 and the mounting ring plate 2. This rotating fit not only ensures flexible adjustment of the tool angle during operation but also enhances the overall stability and durability of the equipment, reduces friction and wear, and extends its service life.

[0036] The beneficial effects of this device are reflected in several aspects: First, through the arrangement of the spray pipe 5 and the nozzle 4, combined with the liquid delivery assembly consisting of the liquid distribution pipe 7 and the liquid delivery pipe 9, and the multiple spray dust suppression structures arranged around the cutter 3 at the bottom of the mounting ring plate 2, a highly efficient water mist dust suppression function is achieved. This fundamentally solves the problems of limited dust suction capacity and easy saturation failure of traditional sponge adsorption methods, avoids the inconvenience caused by frequent replacement of consumables, and significantly improves dust suppression efficiency and environmental performance. Second, the liquid delivery assembly adopts a modular design, which is convenient for maintenance and replacement, while ensuring the uniformity and continuity of liquid delivery, further guaranteeing the stability of the dust suppression effect. Third, the outer ring 13, rotating groove 14, and... The design of the rotating ring 12 allows the mounting ring plate 2 to be flexibly adjusted according to actual operational needs, improving operational flexibility and drilling accuracy. It also enhances structural durability, reduces component wear, and extends the equipment's service life. In addition, the handle 10 and anti-slip groove design in the grip assembly provide a good grip experience, improving operational safety and comfort, and helping to improve work efficiency. Finally, the overall structural layout is reasonable, and the components are coordinated with each other. It retains the portability and economy of the original tools, while achieving the goal of efficient, environmentally friendly, and safe tile drilling through technological optimization, meeting the multiple needs of modern construction for green, healthy, and intelligent development.
