[0038] The embodiment of the present application provides a cleaning head structure, which is commonly used in a cleaning device. The cleaning head structure can be used to clean a tubular inner wall, such as the inner wall of a cold trap of a crystal growth furnace.

[0039] Reference Figures 2 to 4 , the cleaning head structure comprises:

[0040] The cleaning head body 1 has an arc-shaped outer periphery, and a dust suction groove 11 is provided in the middle of the cleaning head body 1. The dust suction groove 11 is used to absorb the attached objects to be cleaned during the cleaning process.

[0041] like Figures 2 to 4 As shown, the outer periphery of the cleaning head body 1 is designed to be arc-shaped, which can better fit the surface to be cleaned, and can achieve close contact regardless of whether the surface to be cleaned is a flat surface or a curved surface. Moreover, the arc-shaped outer periphery can also increase the contact area between the cleaning head body 1 and the surface to be cleaned, thereby improving the cleaning effect of the cleaning head structure.

[0042] In addition, the arc-shaped design of the outer periphery of the cleaning head body 1 allows the user to easily control the direction of the cleaning head body 1 during use to achieve precise cleaning. The arc-shaped shape also makes the cleaning head body 1 smoother when moving, reduces operational resistance, and improves the efficiency of cleaning work.

[0043] In addition, the arc-shaped design also makes the contact between the cleaning head body 1 and the surface to be cleaned smoother, reducing the friction and resistance that may occur during the cleaning process, thereby improving the user experience. Moreover, this design also reduces the hand fatigue that may be caused by long-term use, making the cleaning work easier and more comfortable.

[0044] In actual application, the cleaning head structure can be continuously rotated so that the arc-shaped outer periphery of the cleaning head body 1 can scrape off the attachments on the surface to be cleaned, and the dust suction groove 11 in the middle of the cleaning head body 1 can absorb and recycle the scraped attachments, thereby achieving a cleaning effect. The dust suction groove 11 can be connected to a recycling box, and a negative pressure device can be provided to utilize the pressure difference to absorb the scraped attachments from the dust suction groove 11 into the recycling box, so as to facilitate the reuse of the cleaning head structure.

[0045] Optionally, along the radial cross section of the cleaning head body 1 , the size of the dust suction groove 11 gradually decreases from the inside to the outside.

[0046] like Figure 4 As shown, the size design of the dust suction groove 11 makes the dust suction port narrower at the outer edge of the cleaning head body 1, so that a stronger suction force can be formed during the cleaning process. When the cleaning head body 1 contacts and moves with the surface to be cleaned, this design can more effectively absorb the attached objects on the surface to be cleaned, thereby improving the cleaning efficiency.

[0047] The size of the dust collection groove 11 is designed to gradually decrease from the inside to the outside, which can not only enhance the dust collection effect, but also reduce the risk of the dust collection groove 11 being blocked by large particles during the cleaning process. Even if larger particles are encountered, they can be more easily guided to the entrance of the dust collection groove 11 through the expansion design of the dust collection groove 11, and then sucked away, thereby maintaining the continuous and efficient operation of the cleaning head body 1.

[0048] In addition, by designing the size of the dust suction groove 11 to gradually decrease from the inside to the outside, the cleaning head body 1 can more evenly disperse the pressure when subjected to force, thereby improving the durability and service life of the cleaning head structure.

[0049] Optionally, the angle between the side wall of the dust suction groove 11 and the normal direction ranges from 5 degrees to 30 degrees.

[0050] Specifically, the angle design between the side wall of the dust suction groove 11 and the normal direction helps to form a more concentrated suction force. When the cleaning head body 1 contacts and moves with the surface to be cleaned, the cleaned attachments can enter the dust suction groove 11 more directly and efficiently, thereby improving the cleaning efficiency and cleaning effect.

[0051] The angle between the side wall of the dust collection groove 11 and the normal direction is in the range of 5 to 30 degrees, so that the cleaning head body 1 can adapt to different surfaces to be cleaned. Whether it is a smooth surface to be cleaned or a rough surface to be cleaned, the cleaning head body 1 can maintain a stable dust collection effect to meet the needs of different cleaning scenes.

[0052] In addition, the angle design between the side wall of the dust suction groove 11 and the normal direction also helps to reduce noise and vibration during the dust suction process, making the airflow in the dust suction groove 11 flow more smoothly and reducing the noise caused by airflow turbulence.

[0053] Optionally, the cleaning head body 1 includes a cleaning pad 12 and a cleaning plate 13 , the cleaning pad 12 and the cleaning plate 13 are respectively arc-shaped structures, the outer wall of the cleaning plate 13 is connected to the inner wall of the cleaning pad 12 , and the dust suction groove 11 passes through the cleaning pad 12 and the cleaning plate 13 .

[0054] Specifically, the cleaning pad 12 is usually made of a soft material with a certain friction force, which can effectively wipe or scrape off the attached objects on the surface to be cleaned. The cleaning plate 13 provides a harder surface, which is suitable for scraping off large particles attached to the surface to be cleaned. The combination of the cleaning pad 12 and the cleaning plate 13 can meet different types of cleaning needs and improve the thoroughness and efficiency of cleaning.

[0055] like Figure 2 and Figure 3 As shown, the cleaning pad 12 and the cleaning plate 13 are respectively arranged in an arc-shaped structure, and the outer wall of the cleaning plate 13 is connected to the inner wall of the cleaning pad 12. This design can enhance the stability and durability of the cleaning head structure. During the cleaning process, the arc-shaped structure can better adapt to the surface to be cleaned, thereby improving the cleaning effect.

[0056] The dust collection groove 11 is arranged to penetrate the cleaning pad 12 and the cleaning plate 13, ensuring direct contact between the dust collection groove 11 and the surface to be cleaned. This design allows the cleaned attachments to enter more directly through the dust collection groove 11 during operation. Moreover, the combination of the cleaning pad 12 and the cleaning plate 13 can also effectively push the attachments on the surface to be cleaned toward the dust collection groove 11, further improving the dust collection effect.

[0057] In addition, the cleaning pad 12 and the cleaning plate 13 are detachably connected, such as by bonding or threading, so that users can easily replace and maintain them. When the cleaning pad 12 is worn or needs to be replaced, the user can easily remove it and replace it with a new cleaning pad 12 without replacing the entire cleaning head body 1. This design not only reduces the use cost and maintenance cost, but also improves the sustainable use of the cleaning head structure.

[0058] Optionally, the cleaning plate 13 has a channel 131 , and the channel 131 is communicated with the dust suction groove 11 .

[0059] like Figure 2 and Figure 3 As shown, the channel 131 of the cleaning plate 13 can connect the dust collection slot 11 with the recovery box. During the cleaning process, the channel 131 can guide the attached objects on the surface to be cleaned through the dust collection slot 11 to the connected recovery box or filter box, thereby improving the overall dust collection efficiency.

[0060] The connection design between the channel 131 and the dust collection slot 11 can optimize the airflow path inside the cleaning head structure. The airflow can enter the dust collection slot 11 more smoothly through the channel 131, reducing the resistance and turbulence of the airflow inside the cleaning head structure, making the dust collection effect more ideal. The size of the channel 131 can be adjusted according to actual cleaning needs.

[0061] Moreover, the presence of the channel 131 also enables the cleaning plate 13 to better scrape off the attached objects on the surface to be cleaned during the cleaning process. These attached objects can be quickly sucked in through the dust suction groove 11 and the channel 131, avoiding their accumulation or residue between the cleaning head structure and the surface to be cleaned, thereby further enhancing the cleaning effect.

[0062] In addition, the design of the channel 131 also helps to reduce the risk of the cleaning head structure being blocked. During the cleaning process, even if larger attachments are encountered, they can be guided to the connected recovery box or filter box through the dust suction groove 11 and the channel 131, thereby reducing the possibility of the cleaning head structure being blocked.

[0063] Optionally, the cleaning pad 12 includes a stacked first part 121 and a second part 122, the inner wall of the first part 121 is connected to the outer wall of the second part 122, the inner wall of the second part 122 is connected to the outer wall of the cleaning plate 13, and the thickness of the first part 121 is greater than the thickness of the second part 122.

[0064] like Figure 2 and Figure 3 As shown, through the stacked design of the cleaning pad 12, the first part 121 and the second part 122 can respectively undertake different cleaning tasks, thereby reducing overall wear. When the first part 121 is worn to a certain extent, the part can be replaced alone without replacing the entire cleaning pad 12, which prolongs the service life of the cleaning pad 12 and reduces the use cost of the cleaning pad 12.

[0065] The inner wall of the first part 121 is bonded or threadedly connected to the outer wall of the second part 122, and the inner wall of the second part 122 is bonded or threadedly connected to the outer wall of the cleaning plate 13. This tight connection can enhance the connection reliability and connection stability between the cleaning pad 12 and the cleaning plate 13. During the cleaning process, the cleaning pad 12 is not easy to fall off or shift, ensuring the continuity and stability of cleaning.

[0066] Furthermore, the thickness of the first part 121 is set to be greater than that of the second part 122, that is, the first part 121 is thicker, so that the thicker first part 121 can meet the scene that requires stronger cleaning power, and the thinner second part 122 is used to connect the first part 121 with the cleaning plate 13, which is convenient for the maintenance and replacement of each component. Among them, the first part 121 can be a sponge, and the second part 122 can be a Velcro, which can be bonded to the cleaning plate 13, which can ensure the cleaning effect of the first part 121 while reducing the difficulty of connecting the second part 122 with the cleaning plate 13.

[0067] like Figure 1 As shown, an embodiment of the present application further provides a cleaning device, comprising the above-mentioned cleaning head structure.

[0068] Optionally, it further comprises a handle 2 and a conduit 3 , wherein the conduit 3 is connected between the handle 2 and the cleaning head structure, and the conduit 3 is communicated with the dust suction groove 11 .

[0069] like Figure 1 As shown, the introduction of the handle 2 allows the user to more conveniently manipulate the entire cleaning device. By holding the handle 2, the user can easily move the cleaning head structure to clean the surface to be cleaned. This design reduces the complexity of operation and improves the convenience of use.

[0070] The recovery box or filter box in the handle 2 can be connected to the dust suction groove 11 in the cleaning head structure through the conduit 3, forming a complete dust suction path. When the cleaning device is working, the suction force generated by the handle 2 can be quickly transmitted to the dust suction groove 11 through the conduit 3, thereby effectively sucking the attached matter on the surface to be cleaned into the recovery box or filter box in the handle 2.

[0071] Optionally, the conduit 3 includes a first conduit 31 , a second conduit 32 , and a bent conduit 33 connected between the first conduit 31 and the second conduit 32 , and an angle is formed between the second conduit 32 and the first conduit 31 .

[0072] like Figure 5As shown, the design of the angle between the bent conduit 33 and the second conduit 32 and the first conduit 31 enables the cleaning device to adapt to different surfaces to be cleaned, thereby improving the flexibility of the cleaning device. The first conduit 31, the second conduit 32 and the bent conduit 33 each have an air flow channel, one end of the air flow channel is connected to the dust collection slot 11, and the other end of the air flow channel is connected to the recovery box or the filter box in the handle 2.

[0073] The design of the bent conduit 33 can optimize the dust collection path, so that the airflow can enter the dust collection slot 11 more smoothly through the conduit 3. The existence of the angle between the second conduit 32 and the first conduit 31 can reduce the resistance of the airflow in the conduit 3, improve the dust collection efficiency, and also increase the overall stability and durability of the conduit 3. This structure can better resist external shocks and vibrations, reduce the risk of deformation or damage of the conduit 3 during use, and thus extend the service life of the cleaning device.

[0074] In addition, the existence of the curved conduit 33 and the angle between the second conduit 32 and the first conduit 31 also makes the cleaning device more ergonomic, reducing the discomfort and fatigue that may be caused by long-term use. According to actual production needs, the first conduit 31, the second conduit 32 and the curved conduit 33 can be an integrated design or a split design.

[0075] Optionally, the first conduit 31 is connected to the cleaning head structure, the second conduit 32 is connected to the handle 2 , and along the height direction of the cleaning device, the top of the first conduit 31 is inclined toward the handle 2 .

[0076] like Figure 5 As shown, the first conduit 31 can be an inclined tube, and the second conduit 32 can be a horizontal tube, which can facilitate the connection of the two. The top of the first conduit 31 is arranged to be inclined toward the handle 2 along the height direction of the cleaning device, so that the cleaned attachments can rise more smoothly when passing through the first conduit 31, reducing the resistance of the cleaned attachments in the first conduit 31. This design helps to improve the dust collection efficiency and ensure that the cleaning device can quickly suck away the cleaned attachments when working. Among them, according to the actual layout requirements, the top of the first conduit 31 can be arranged to be inclined 5 to 10 degrees toward the handle 2, which can adapt to the surface to be cleaned.

[0077] Furthermore, the inclined design of the first conduit 31 enables the user to hold the handle 2 more naturally when operating the cleaning device, and does not need to bend or twist the body excessively to adapt to the angle of the conduit 3. This design reduces the difficulty of operation, improves the convenience of use, and makes cleaning easier and more comfortable. Moreover, the inclined design also makes the transition between the first conduit 31 and the bent conduit 33 more natural and smooth, thereby making the appearance of the entire cleaning device more beautiful.

[0078] Optionally, the thickness of the top of the first conduit 31 is smaller than the thickness of the bottom of the first conduit 31 .

[0079] Specifically, by reducing the thickness of the top of the first conduit 31, the entire upper portion of the first conduit 31 becomes lighter. This allows the user to feel less resistance and a more relaxed operating experience when operating the cleaning device, especially when the cleaning head structure needs to be lifted or moved. This design reduces hand fatigue that may be caused by long-term use and improves the convenience of operation.

[0080] The thickness of the bottom of the first conduit 31 is greater than or equal to the thickness of the top of the first conduit 31, that is, the thickness of the bottom of the first conduit 31 is kept relatively large, thereby ensuring the overall structural strength and stability of the first conduit 31. This design can prevent the first conduit 31 from being deformed or damaged during use while keeping it light, thereby extending the service life of the cleaning device. For example, the thickness of the bottom of the first conduit 31 can be set to be about 3 mm to 4 mm, and the thickness of the top of the first conduit 31 can be set to be about 2 mm, which can adapt to the surface to be cleaned.

[0081] In addition, the thinner top design of the first duct 31 also helps to reduce the resistance of the attachments at the top of the first duct 31, allowing the attachments to pass through the first duct 31, the bent duct 33 and the second duct 32 more smoothly and enter the recovery box or filter box in the handle 2, thereby helping to improve the dust collection efficiency.

[0082] Optionally, the handle 2 includes a handle body 21, at least one filter element 22 and a third conduit 23, the handle body 21 has a accommodating cavity, the filter element 22 is located in the accommodating cavity, one end of the filter element 22 is connected to the conduit, the other end of the filter element 22 is connected to the third conduit 23, and the third conduit 23 is connected to the negative pressure device.

[0083] like Figure 6 and Figure 7 As shown, by providing a receiving cavity in the handle body 21 and placing the filter element 22 therein, the attached matter sucked through the catheter 3 can be filtered by at least one filter element 22, so that the attached matter can be recovered.

[0084] Among them, one end of the filter element 22 is connected to the conduit 3, and the other end of the filter element 22 is connected to the third conduit 23. This design ensures that the compressed air generated by the negative pressure device can form a negative pressure environment in the third conduit 23, the filter element 22, the conduit 3 and the dust suction groove 11, so that the cleaned attachments can flow into the filter element 22 through the dust suction groove 11 and the conduit 3 driven by the pressure difference.

[0085] In addition, since the filter 22 is located in the accommodating cavity of the handle body 21, this design makes it easier to replace and maintain the filter 22. The user only needs to open the handle body 21 to easily remove and replace the filter 22 without disassembling the entire cleaning device, saving time and effort.

[0086] Optionally, the handle 2 includes two filters 22, one filter 22 is a hollow cylindrical structure, and the other filter 22 is a mesh structure, the filter cavity of the hollow cylindrical structure is connected to the conduit 3, and one end of the hollow cylindrical structure away from the conduit 3 abuts against the mesh structure.

[0087] like Figure 6 and Figure 7 As shown, by combining two different types of filter elements 22, the hollow cylindrical structure and the mesh structure, multi-stage filtration of the inhaled attachments can be achieved. The hollow cylindrical structure first filters out the larger attachments and intercepts the larger attachments in the filter cavity of the hollow cylindrical structure, and then the mesh structure can further intercept the remaining fine attachments, thereby coordinating the filtration and recovery of the attachments, and improving the cleaning efficiency and cleaning effect of the cleaning device.

[0088] The filter cavity of the hollow cylindrical structure is directly connected to the conduit 3, which can ensure smooth entry of attachments. In addition, the end of the hollow cylindrical structure away from the conduit 3 is arranged to abut against the mesh structure. This design allows the tiny attachments passing through the hollow cylindrical structure to be gathered on the filter element 22 of the mesh structure, thereby achieving a cleaning function. A fixing ring can be designed at the connection between the filter element 22 of the hollow cylindrical structure and the conduit 3, and the fixing ring can be used to strengthen the connection strength between the two.

[0089] After cleaning, the handle 2 can be disassembled and the attachments on the filter cavity of the hollow cylindrical structure and the filter element 22 of the mesh structure can be cleaned for subsequent use.

[0090] The mesh filter 22 may be a velvet cloth filter, which can provide a larger filtering area, thereby increasing the filtering capacity and efficiency. Moreover, the mesh structure can effectively capture and accommodate more attachments, extend the service life of the filter 22, and reduce the need for frequent replacement.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
