Description

Technical Field

[0001] This application relates to the field of cleaning technology, specifically to a cleaning device. Background Technology

[0002] Currently, the blind holes at one end of medical ultrasonic scalpel rods are small in diameter and deep, making it difficult to completely remove oil, chips, residues, and other impurities. Ultrasonic cleaning or hydrocarbon vacuum cleaning is commonly used. However, ultrasonic cleaning cannot effectively cavitate the small and deep blind holes, making it difficult for organic solvents to penetrate. This results in incomplete removal of oil and debris, ultimately leading to poor cleaning results. Hydrocarbon vacuum cleaning, based on the principle of "like dissolves like" in organic solvents, is effective at removing oil from blind holes in a vacuum environment, but it struggles to remove debris and other foreign matter. These shortcomings not only affect the cleanliness of the ultrasonic scalpel rod but may also lead to performance degradation and a shortened lifespan during use, failing to meet the demands of high-precision medical surgery. Utility Model Content

[0003] In view of the above, it is necessary to propose a cleaning device for cleaning foreign matter residue in blind holes of workpieces.

[0004] One embodiment of this application provides a cleaning device for cleaning blind holes opened at one end of a workpiece.

[0025] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1 and Figure 2 This application provides a cleaning device 100 for cleaning a blind hole 210 at one end of a workpiece 200. In this embodiment, the workpiece 200 is rod-shaped, and the diameter of the blind hole 210 is less than 3 mm and the depth is greater than 6 mm. The cleaning device 100 includes a positioning component 10 and a cleaning component 20.

[0027] Please see also Figure 3 The positioning assembly 10 includes a positioning element 11 and a support element 12. The positioning element 11 is provided with multiple positioning parts 111, each of which is used to position the workpiece 200. The support element 12 is connected to one side of the positioning element 11. The cleaning assembly 20 includes multiple cleaning elements 21 and a liquid-passing element 22. The cleaning elements 21 are tubular structures. Both the cleaning elements 21 and the liquid-passing element 22 are hollow structures and connected to each other. The multiple cleaning elements 21 are disposed on the support element 12 and are respectively arranged opposite to the multiple positioning parts 111. The liquid-passing element 22 is disposed on the support element 12. One end of the liquid-passing element 22 is connected to the multiple cleaning elements 21, and the other end of the liquid-passing element 22 is used to connect to a water pump. The liquid-passing element 22 introduces high-pressure cleaning fluid through the water pump and allows the high-pressure cleaning fluid to enter the multiple cleaning elements 21. The high-pressure cleaning fluid in the multiple cleaning elements 21 is injected into the blind holes 210 of the workpiece 200 on the corresponding positioning parts 111 to flush the blind holes 210.

[0028] In the cleaning device 100 described above, the workpiece 200 is first placed on the positioning part 111 of the positioning part 11 so that the cleaning part 21 is opposite to the positioning part 111. Then, the cleaning device 100 is placed in the ultrasonic cleaning device for vibration cleaning, so that the residual powder is shaken off. After that, the liquid passage part 22 introduces high-pressure cleaning fluid through the water pump and makes the high-pressure cleaning fluid enter multiple cleaning parts 21. The high-pressure cleaning fluid in the multiple cleaning parts 21 is injected into the blind holes 210 of the workpiece 200 on the corresponding positioning part 111, thereby rinsing the blind holes 210. The oil stains are separated from the workpiece 200 through a series of interactive cleaning actions such as saponification, emulsification, dispersion, wetting, and solubilization of the cleaning fluid, thereby removing the residue and other foreign matter, and the cleaning effect is good.

[0029] Please see also Figure 4 In some embodiments, the positioning member 11 includes a support portion 112, a first limiting portion 113, and a second limiting portion 114. The support portion 112 is a long plate and is spaced apart. The first limiting portion 113 and the second limiting portion 114 are both long strips and are arranged perpendicular to the support portion 112. The first limiting portion 113 and the second limiting portion 114 are spaced apart on the support portion 112 along a first direction. The carrier member 12 is located on the side of the first limiting portion 113 away from the second limiting portion 114 and is connected to the support portion 112. The positioning portion 111 includes a first limiting groove 1111 and a second limiting groove 1112 that both extend along the first direction. The first limiting groove 1111 and the second limiting groove 1112 are both through grooves. The first limiting groove 1111 is formed in the first limiting portion 113, and the second limiting groove 1112 is formed in the second limiting portion 114. The workpiece 200 is disposed in the first limiting groove 1111 and the second limiting groove 1112. In this embodiment, there are two support portions 112 that are spaced apart along a second direction perpendicular to the first direction. The first direction is the X-axis direction and the second direction is the Y-axis direction. The size of the first limiting portion 113 is larger than the size of the second limiting portion 114. There are two second limiting portions 114 that are spaced apart along the first direction.

[0030] In some embodiments, the carrier 12 is provided with a first branch 121 and a plurality of second branches 122 communicating with the first branch 121. The first branch 121 is connected to the fluid-conducting component 22. The plurality of second branches 122 are respectively disposed corresponding to a plurality of first limiting grooves 1111. A plurality of cleaning components 21 are respectively disposed in the plurality of second branches 122, with one end of each cleaning component 21 extending into the corresponding first limiting groove 1111. In this embodiment, the first branch 121 and the plurality of second branches 122 are arranged perpendicularly. In this way, high-pressure cleaning fluid can be simultaneously introduced into the plurality of cleaning components 21 through the fluid-conducting component 22, thereby allowing the plurality of cleaning components 21 to flush the blind holes 210 of the plurality of workpieces 200.

[0031] In some embodiments, the positioning member 11 further includes a supporting portion 13, which is strip-shaped. The first limiting portion 113 has a receiving groove 1131 extending along a second direction perpendicular to the first direction. The receiving groove 1131 communicates with the first limiting groove 1111. The supporting portion 13 is disposed at the bottom of the receiving groove 1131 to support the workpiece 200. Thus, by providing the supporting portion 13 and placing it at the bottom of the receiving groove 1131, not only can the workpiece 200 be supported, but the workpiece 200 can also be suspended, facilitating the discharge of oil and foreign matter from the blind hole 210 and preventing them from adhering to the bottom of the receiving groove 1131.

[0032] In some embodiments, a plurality of locking holes 123 are provided on one side of the carrier 12. Each locking hole 123 corresponds to a plurality of second branches 122. One end of each locking hole 123 is connected to the corresponding second branch 122, and the other end is connected to the outside. A locking element (not shown) is installed inside the locking hole 123 to secure the cleaning component 21 installed in the second branch 122. In this embodiment, the locking hole 123 is a threaded hole, and the locking element is a screw. Thus, by providing the locking hole 123 and installing the locking element, the cleaning component 21 installed in the second branch 122 can be fixed, preventing the cleaning component 21 from being flushed out of the second branch 122 by the high-pressure cleaning fluid when the liquid-conducting component 22 flows through it.

[0033] Please see also Figure 5 In some embodiments, the cleaning device 100 further includes a protective frame 30, which includes a frame 31 and a first connecting member 32. The frame 31 has a frame chamber 311, in which the positioning component 10 and the cleaning component 21 are both disposed. The positioning component 10 further includes a second connecting member 14 disposed on the side of the support portion 112. The first connecting member 32 is disposed within the frame chamber 311 and is detachably connected to the second connecting member 14. In this embodiment, the first connecting member 32 has a U-shaped structure, and the second connecting member 14 is a screw. By setting the frame 31 and the first connecting member 32, protection for the positioning component 10 can be formed, and disassembly and assembly are convenient.

[0034] In some embodiments, the protective frame 30 further includes a protective cover 33 and a plurality of pressing members 34. The frame 31 has a frame opening 312 communicating with the frame chamber 311. The protective cover 33 is disposed on the frame opening 312 of the frame 31, and the plurality of pressing members 34 are disposed on opposite sides of the frame opening 312 of the frame 31 for pressing the protective cover 33 against the frame opening 312 during rotation. Thus, by providing pressing members 34 on opposite sides of the frame opening 312 of the frame 31, after the first connecting member 32 and the second connecting member 14 are connected, the plurality of pressing members 34 can press the protective cover 33 tightly against the frame opening 312 of the frame 31.

[0035] In some embodiments, the plurality of pressing members 34 include a first pressing part 341, which includes a fixed body 3411 and a rotating rod 3412. The fixed body 3411 is fixed to the frame opening 312 of the frame 31, and the rotating rod 3412 is rotatably mounted on the fixed body 3411 for pressing the protective cover 33 onto the frame opening 312 when rotated. In this embodiment, there are two first pressing parts 341, which are spaced apart. The fixed body 3411 is a cylindrical structure, and the rotating rod 3412 is an L-shaped structure. The rotating rod 3412 and the fixed body 3411 are connected by threads. Thus, by rotating the rotating rod 3412, one end of the rotating rod 3412 can be rotated to the top of the protective cover 33 and press it onto the protective cover 33 at the frame opening 312.

[0036] In some embodiments, the plurality of pressing members 34 further include a second pressing portion 342, which includes a connecting body 3421, a pressing rod 3422, and an elastic body 3423. The connecting body 3421 is disposed at the frame opening 312 of the frame 31. The pressing rod 3422 is rotatably connected to the connecting body 3421 and has opposing abutting ends 3422a and pressing ends 3422b. The two ends of the connecting body 3421 are located between the abutting ends 3422a and the pressing ends 3422b. The elastic body 3423 is sleeved on the pressing rod 3422, and the two ends of the elastic body 3423 abut against the abutting ends 3422a and the connecting body 3421, respectively. The pressing end 3422b is used to elastically press against the protective cover 33 of the frame opening 312 during rotation. In this embodiment, the connecting body 3421 is a columnar structure, the pressing rod 3422 is a T-shaped structure, and the elastic body 3423 is a spring. Thus, by setting the pressure rod 3422, the pressing end 3422b of the pressure rod 3422 can be rotated to the top of the protective cover 33 and pressed against the protective cover 33 of the frame opening 312; by setting the elastic body 3423, one end of the pressure rod 3422 can be elastically pressed against the protective cover 33 of the frame opening 312.

[0037] Please continue reading Figure 4 In some embodiments, the fluid-conducting component 22 includes multiple fluid-conducting pipes 221 and multiple pipe fittings 222. The multiple fluid-conducting pipes 221 are respectively connected to the first branch 121. Each pipe fitting 222 has one fluid-conducting pipe 221 connected to its end furthest from the positioning component 10, and two fluid-conducting pipes 221 connected to its end closest to the positioning component 10. The ends of the two fluid-conducting pipes 221 connected to one pipe fitting 222 are connected to the first branch 121 or the end of another pipe fitting 222 furthest from the positioning component 10. Thus, by providing multiple fluid-conducting pipes 221 and multiple pipe fittings 222, the high-pressure cleaning fluid can flow evenly into the carrier component 12, resulting in a better cleaning effect.

[0038] In this embodiment, the pipe connector 222 is a flat tee pipe. Multiple fluid-conducting pipes 221 include a first conduit 221a, a second conduit 221b, a third conduit 221c, and a fourth conduit 221d. Multiple pipe fittings 222 include a first fitting 222a and a second fitting 222b. One end of the first conduit 221a, the second conduit 221b, and the third conduit 221c are connected side-by-side to one side of the support member 12 and are respectively connected to the first branch 121. The first conduit 221a and the second conduit 221b are arranged adjacent to each other, and the other end of the first conduit 221a and the second conduit 221b are both connected to one side of the first fitting 222a and are both connected to one side of the first fitting 222a. One end of the fourth conduit 221d is connected to the other side of the first fitting 222a and is connected to the first fitting 222a. The other end of the fourth conduit 221d and the other end of the third conduit 221c are both connected to one side of the second fitting 222b and are both connected to the second fitting 222b.

[0039] The implementation process of the cleaning device 100 in this application embodiment is as follows:

[0040] Multiple workpieces 200 are placed in the first limiting groove 1111 of the first limiting part 113 and the second limiting groove 1112 of the second limiting part 114, and the lifting part 13 supports the workpieces 200. At this time, one end of the multiple cleaning parts 21 extending into the first limiting groove 1111 is respectively positioned opposite to the blind hole 210 of the multiple workpieces 200.

[0042] The protective cover 33 is placed on the frame opening 312 of the frame 31, and the rotating rod 3412 and the pressing rod 3422 are rotated so that one end of the rotating rod 3412 rotates to the top of the protective cover 33 and presses it on one side of the protective cover 33 in the frame opening 312, and the pressing end 3422b of the pressing rod 3422 rotates to the top of the protective cover 33 and elastically presses it on the protective cover 33 in the frame opening 312.

[0043] The cleaning device 100 is placed in a cleaning tank containing cleaning fluid, which may be a degreasing agent.

[0044] The liquid-passing component 22 introduces high-pressure cleaning fluid through a water pump, which then enters multiple cleaning components 21. The high-pressure cleaning fluid in the multiple cleaning components 21 is injected into the blind holes 210 of the workpiece 200 on the corresponding positioning part 111, thereby rinsing the blind holes 210. During rinsing, the oil stains are separated from the workpiece 200 through a series of interactive cleaning actions such as saponification, emulsification, dispersion, wetting, and solubilization of the cleaning fluid, thereby removing residual debris and other foreign matter.
