Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a cleaning device and a diagnostic and treatment device. Background Technology

[0002] Computed Tomography (CT), also known as a CT X-ray scanner, uses a precisely collimated X-ray beam and a highly sensitive detector to scan a specific part of the human body one section after another. It features fast scanning time and clear images and can be used to examine a variety of diseases.

[0003] Computed tomography (CT) scanners consist of a fixed frame, a rotating body, and slip rings mounted on the rotating body. Carbon rods are fixed to the frame and contact the slip rings in the rotating body, achieving electrical conductivity through friction between the slip rings and the carbon rods. The carbon rods are primarily made of graphite. During operation, the slip rings rotate at high speed, and the carbon rods generate dust through friction on the ring surface. Long-term accumulation of this dust can lead to poor power transmission and even sparking, resulting in equipment malfunctions and property damage.

[0004] Currently, the cleaning and maintenance of slip rings mainly relies on regular manual cleaning and wiping. This method is not only labor-intensive but also inefficient, often resulting in untimely and incomplete cleaning. Furthermore, the scattered dust can easily enter the equipment, causing potential hazards. Some technologies use a drive device to rotate a brush wheel and a suction pump to adsorb toner, effectively removing it from the slip rings. However, both the drive device and the suction pump in these technologies require electricity, leading to high energy consumption for cleaning toner. Utility Model Content

[0005] The purpose of this application is to provide a cleaning device and a diagnostic device, which aims to solve the problems of low efficiency and high energy consumption when cleaning carbon powder on slip rings in related technologies.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] In a first aspect, this application provides a cleaning device, including a box body and a brush wheel, a fan blade assembly, and a storage component disposed inside the box body; the brush wheel is disposed in contact with a slip ring, and when the slip ring rotates, it can drive the brush wheel to rotate to brush off waste on the slip ring; the fan blade assembly is connected to the brush wheel and can rotate with the rotation of the brush wheel to form an airflow inside the box body to transport the waste to the storage component for collection.

[0008] In this embodiment, the brush wheel is positioned in contact with the slip ring. Thus, when the slip ring rotates, the friction between the brush wheel and the slip ring drives the brush wheel to rotate. This rotation effectively removes dust from the slip ring surface, achieving a cleaning function and reducing the impact of dust on the slip ring's normal operation, thereby improving the slip ring's performance and lifespan. Furthermore, since the brush wheel is driven by the slip ring's own rotation, no additional power source is needed to drive it. This allows the cleaning device to operate passively, reducing its complexity and cost, minimizing energy consumption, and improving its operational efficiency and stability.

[0009] Furthermore, in this embodiment, the fan blade assembly is connected to the brush wheel. When the brush wheel rotates, it drives the fan blade assembly to rotate, thereby creating airflow inside the housing. The airflow can carry the waste brushed off by the brush wheel and transport it to the storage container, preventing waste from accumulating inside the housing and ensuring the cleanliness of the cleaning device. It also facilitates the centralized disposal of waste, preventing waste (such as dust) from flying in the surrounding environment. This not only helps maintain a clean working environment but also prevents waste from re-adhering to the slip ring or other equipment, further improving the cleaning effect of the cleaning device.

[0010] In some embodiments of this application, the cleaning device further includes: a rotating shaft rotatably connected to the housing, and the brush wheel and fan blade assembly connected via the rotating shaft.

[0011] In some embodiments of this application, the slip ring has multiple tracks; multiple brush wheels are provided, each brush wheel is connected to a rotating shaft, and the multiple brush wheels are configured to correspond one-to-one with the multiple tracks of the slip ring to brush off waste in the multiple tracks.

[0012] In some embodiments of this application, the brush wheel is coaxially arranged with the rotating shaft.

[0013] In some embodiments of this application, the fan blade assembly is coaxially arranged with the rotation shaft.

[0014] In some embodiments of this application, the box body is provided with a connected inlet and outlet, at least a portion of the brush wheel is provided at the inlet, and the storage component is connected to the outlet.

[0015] In some embodiments of this application, the storage component is provided with a storage space for containing dust, and the storage component is provided with a storage inlet communicating with the storage space, and the storage inlet is connected to the outlet.

[0016] In some embodiments of this application, the cleaning device further includes a first bearing, which includes a first inner ring and a first outer ring that are rotatable relative to each other. The first outer ring is connected to the housing, and the first inner ring is connected to the rotating shaft.

[0017] In some embodiments of this application, the cleaning device further includes: a second bearing, disposed at opposite ends of the rotating shaft to the first bearing; the second bearing includes a second inner ring and a second outer ring capable of relative rotation, the second outer ring being connected to the housing and the second inner ring being connected to the rotating shaft.

[0018] Secondly, this application also provides a diagnostic and treatment device, including a slip ring, a frame, and a cleaning device described in the first aspect above, wherein the slip ring is rotatably connected to the frame, and the cleaning device is disposed on the frame.

[0019] The technical effects brought about by the second aspect described above can be referred to the technical effects brought about by the corresponding embodiments in the first aspect, and will not be repeated here. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0031] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0032] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0033] First, for ease of understanding, the terms used in this application will be explained.

[0034] (1) Slip ring: Also known as a current collector ring, slip ring, etc., it is an electromechanical component used to realize electrical connection between rotating and stationary parts. The working principle of the slip ring is based on the sliding contact between the relatively moving brush and the conductive ring. When the rotating part drives the conductive ring to rotate, the brush always maintains good contact with the conductive ring, thereby realizing the continuous transmission of current between the rotating and stationary parts. No matter how the rotating part rotates, the brush will slide on the surface of the conductive ring to ensure the conduction of the circuit, thereby providing power and signal transmission channels for various parts of the rotating equipment.

[0035] (2) Diagnostic and therapeutic equipment: refers to the general term for various instruments, equipment and appliances used in the diagnosis, treatment, monitoring and rehabilitation processes in the medical process.

[0036] In some diagnostic and treatment devices, the equipment needs to rotate continuously around the patient to acquire tomographic images of the body from different angles. Slip rings, through the friction and conductivity between brushes (such as carbon rods) and their own tracks, connect the power and signals from the stationary part to the rotating part. This allows the diagnostic and treatment device to continuously receive power and transmit signals during rotation, enabling continuous rotational scanning and significantly improving scanning efficiency and image quality. Therefore, slip rings are the main power and signal transmission devices in CT scanners and next-generation circular accelerators.

[0037] However, during the operation of the slip ring, the carbon rod, as a key conductive component, faces unavoidable physical wear. As the slip ring continues to operate, the carbon rod and the track surface are in a state of high-frequency contact friction, constantly generating carbonaceous debris and fine powder. These wear products do not dissipate automatically but continuously adhere to the track surface, accumulating over time to form stains.

[0038] As contaminants accumulate on the track surface, they gradually affect the normal operation of the diagnostic and treatment equipment. First, the presence of the contaminant layer interferes with normal electrical signals and energy transmission, causing current transmission obstruction. The originally smooth power and data transmission channels become disrupted due to increased contact resistance and signal attenuation caused by carbon powder buildup, leading to adverse consequences such as decreased transmission efficiency and signal distortion.

[0039] Secondly, as dirt accumulates, the electric field distribution on the slip ring surface becomes unbalanced, easily inducing partial discharge. When the charge accumulates to a certain level, the air medium is instantly broken down, forming a visible electric spark, also known as arcing. This arcing not only generates high temperatures that burn the slip ring components, accelerating equipment aging, but also releases electromagnetic interference, disrupting the normal operating environment of surrounding electronic equipment.

[0040] Based on this Figure 1 This application provides a partial structural schematic diagram of a diagnostic and treatment device according to an embodiment. Please refer to [link / reference]. Figure 1 The diagnostic and treatment device 100 includes: a cleaning device 10, a slip ring 20, and a gantry. The diagnostic and treatment device 100 includes, but is not limited to, CT equipment, medical linear accelerators, medical surgical robots, and digital subtraction angiography (DSA) equipment.

[0041] The slip ring 20 is rotatably connected to the frame. Optionally, the slip ring 20 can be rotatably connected to the frame via a flange, or alternatively, it can be rotatably connected to the frame via a bushing or bearing; this application does not limit the specific connection.

[0042] In addition, the cleaning device 10 is mounted on the frame. Optionally, the cleaning device 10 can be fixedly connected to the frame by means of bonding, threaded connection, welding, snap-fit, etc. Optionally, part of the cleaning device 10 can also be integrally formed with the frame, that is, part of the cleaning device 10 and the frame are a single structural component.

[0043] In some embodiments of this application, the cleaning device 10 includes: a housing 11, a brush wheel 12, a fan blade assembly 13, and a storage component 14. The brush wheel 12 and the fan blade assembly 13 may be disposed within the housing 11. The storage component 14 may be an object with storage space, such as a storage bag or storage box, and this application does not limit its use.

[0044] The housing 11 serves as the basic frame of the cleaning device 10. The housing 11 can be made of a high-strength and wear-resistant material. Optionally, the housing 11 can be made of a high-strength and wear-resistant plastic material, such as polycarbonate (PC) or polyetheretherketone (PEEK). Optionally, the housing 11 can also be made of a high-strength and wear-resistant metal material, such as aluminum alloy or stainless steel. Optionally, the housing 11 can also be a composite material, such as glass fiber reinforced plastic (FRP). This application does not limit the choice of materials.

[0045] Additionally, the brush wheel 12 is positioned in contact with the slip ring 20. When the slip ring 20 rotates, it drives the brush wheel 12 to rotate, thereby brushing off waste from the slip ring 20. For example, this waste may include carbon rod dust and airborne dust. The brush wheel 12 is the direct actuator for cleaning the slip ring 20. The surface of the brush wheel 12 may be arranged with multiple rows of elastic bristles. Thus, when the brush wheel 12 rotates, the friction between the bristles and the slip ring 20 cleans away the dirt adhering to the slip ring 20, ensuring the surface of the slip ring 20 is clean.

[0046] To improve the service life of the brush wheel 12 and avoid damaging the surface of the pulley, the brush wheel 12 can be made of a material with moderate hardness and good toughness, such as nylon or synthetic rubber. This ensures that the brush wheel 12 will not damage the surface of the slip ring 20 during cleaning and has a long service life.

[0047] Furthermore, the fan blade assembly 13 is connected to the brush wheel 12 and rotates with the brush wheel 12 to create airflow inside the box 11, transporting waste to the collection component 14 for collection. That is, the fan blade assembly 13 is primarily responsible for promptly expelling the dirt cleaned by the brush wheel 12 from the box 11, preventing dirt accumulation inside. Optionally, the fan blade can be made of lightweight and high-strength plastic material, such as polyamide (PA) or polyoxymethylene (POM). Optionally, the box 11 can also be made of aluminum alloy; this application does not limit this.

[0048] The fan blade assembly 13 includes a connecting part and multiple fan blades. The multiple fan blades are arranged circumferentially around the connecting part, and all the fan blades are fixedly connected to the connecting part. The connecting part can be fixedly connected to the brush wheel 12 through a connector (i.e., the rotating shaft described later). In this way, when the slip ring 20 drives the brush wheel 12 to rotate, it can drive the connecting part to rotate as well, thereby driving the multiple fan blades to rotate together. This creates a strong airflow inside the housing 11, blowing the powder, debris, and other dirt swept up by the brush wheel 12 into the storage component 14.

[0049] It is understood that the number of fan blades can be three, four, five, or six, etc., and this application does not limit this. In addition, the fan blades can be streamlined propeller-shaped, and the connecting part can be provided with a ring-shaped or cylindrical streamlined structure, thereby reducing the air resistance when the fan blade assembly 13 rotates, thereby improving the airflow efficiency.

[0050] In this embodiment, the brush wheel 12 is positioned in contact with the slip ring 20. Thus, when the slip ring 20 rotates, the friction between the brush wheel 12 and the pulley drives the brush wheel 12 to rotate. This rotation effectively removes dust from the surface of the slip ring 20, achieving a cleaning function and reducing the impact of dust on the normal operation of the slip ring 20, thereby improving its performance and lifespan. Furthermore, since the brush wheel 12 is driven by the rotation of the slip ring 20 itself, no additional power source is needed to drive it. This allows the cleaning device 10 to operate passively, reducing its complexity and cost, minimizing energy consumption, and improving its operational efficiency and stability.

[0051] Furthermore, in this embodiment, the fan blade assembly 13 is connected to the brush wheel 12. When the brush wheel 12 rotates, it drives the fan blade assembly 13 to rotate, thereby forming an airflow inside the housing 11. The airflow can carry the waste brushed off by the brush wheel 12 and transport it into the storage component 14, which can prevent waste from accumulating inside the housing 11, ensuring the cleanliness of the inside of the cleaning device 10. It also facilitates the centralized treatment of waste, preventing waste (such as dust) from flying in the surrounding environment. This not only helps maintain a clean working environment but also prevents waste from re-adhering to the slip ring 20 or other equipment, further improving the cleaning effect of the cleaning device 10.

[0052] In some embodiments of this application, the cleaning device 10 further includes a rotating shaft 15, which is rotatably connected to the housing 11. The brush wheel 12 and the fan blade assembly 13 are connected via the rotating shaft 15. That is, at least a portion of the rotating shaft 15 is disposed within the housing 11, and the brush wheel 12 and the fan blade assembly 13 are fixed within the portion located within the housing 11. The brush wheel assembly 12 and the fan blade assembly 13 can be fixedly connected to the rotating shaft 15 by means of bonding, threaded connection, welding, snap-fit, etc., and this application does not limit this method.

[0053] The rotating shaft 15 can be made of a material with high strength and high wear resistance. For example, the material of the rotating shaft 15 can be metal such as carbon steel or stainless steel, or plastic such as polycarbonate (PC) or nylon (PA). This application does not limit the material of the rotating shaft 15.

[0054] Because the brush wheel 12 and the fan blade assembly 13 are connected via the rotating shaft 15, the power transmitted when the slip ring 20 rotates can be more stable. This reduces power loss caused by unstable connection, ensuring that the brush wheel 12 and the fan blade assembly 13 can rotate in the expected manner, thereby improving the cleaning effect.

[0055] In some embodiments of this application, the brush wheel 12 is coaxial with the rotating shaft 15, that is, the central axis of the brush wheel 12 is collinear with the central axis of the rotating shaft 15.

[0056] Because the brush wheel 12 is coaxially arranged with the rotating shaft 15, the brush wheel 12 maintains a stable center of rotation during rotation. This ensures more uniform contact between the brush wheel 12 and the slip ring 20 when brushing off waste, preventing localized over- or under-cleaning caused by eccentric rotation. Furthermore, the coaxial arrangement allows the brush wheel 12 to efficiently receive power from the rotating shaft 15. The rotation of the rotating shaft 15 can be directly and losslessly transmitted to the brush wheel 12, reducing energy loss and power loss during power transmission.

[0057] In some embodiments of this application, the fan blade assembly 13 is coaxially arranged with the rotating shaft 15. That is, the rotation center line of the connecting part is collinear with the central axis of the rotating shaft 15.

[0058] Since the fan blade assembly 13 is coaxially arranged with the rotating shaft 15, the stability and uniformity of the airflow are ensured, which helps to more effectively transport the waste brushed off by the brush wheel 12 into the collection component 14. In addition, the rotating shaft 15 can directly and accurately transmit power to the fan blade assembly 13, reducing energy loss during power transmission and ensuring that the fan blade assembly 13 can obtain a stable rotation speed, thereby ensuring consistent airflow intensity.

[0059] Figure 2The embodiments provided in this application are shown. Figure 1 For a magnified view of the part, please refer to [link / reference]. Figure 1 and Figure 2 In some embodiments of this application, the slip ring 20 has multiple tracks 21. Multiple brush wheels 12 are provided, each connected to a rotating shaft 15, and each brush wheel 12 is configured to correspond one-to-one with one of the multiple tracks 21 of the slip ring 20 to brush away waste within the multiple tracks 21. The multiple brush wheels 12 can be arranged axially along the rotating shaft 15 and are all fixedly connected to the rotating shaft 15.

[0060] For example, such as Figure 2 As shown, the slip ring 20 has 9 tracks 21 and 9 brush wheels 12. The 9 brush wheels 12 are respectively arranged in the 9 tracks 21 to brush off the waste in the 9 tracks 21.

[0061] In this way, multiple brush wheels 12 work simultaneously, thereby improving cleaning efficiency. Compared to a single brush wheel 12 cleaning multiple tracks 21, the multiple brush wheels 12 can clean multiple tracks 21 at the same time, completing the cleaning of the slip ring 20 in a shorter time, thereby reducing equipment downtime for maintenance and improving maintenance efficiency.

[0062] In some embodiments of this application, the housing 11 is provided with a connected inlet and outlet, at least a portion of the brush wheel 12 is provided at the inlet, and the storage component 14 is connected to the outlet.

[0063] The box 11 may have a receiving space inside, and a part of the brush wheel 12 and the fan blade assembly 13 may be located in the receiving space. The box 11 is provided with an inlet and an outlet that are connected to the receiving space. At least a part of the brush wheel 12 is in contact with the slip ring 20 through the inlet, and the outlet is connected to the storage component 14.

[0064] Since the brush wheel 12 is at least partially located at the inlet, it can directly clean the waste on the surface of the slip ring 20 when the slip ring 20 rotates. After the waste is brushed off, it can smoothly enter the box 11 from the inlet using the rotation of the brush wheel 12 and its own inertia, improving the efficiency of waste entering the box 11 and reducing the possibility of waste remaining around the slip ring 20. Since the inlet and outlet of the box 11 are connected, when the fan blade assembly 13 rotates to form an airflow, the airflow can form a relatively smooth flow path inside the box 11. Waste entering from the inlet can move towards the outlet along the channel inside the box 11 under the action of the airflow and is eventually collected by the collection component 14. This helps to improve the waste collection efficiency and avoids the accumulation of waste inside the box 11.

[0065] In some embodiments of this application, the storage component 14 is provided with a storage space for accommodating dust, and the storage component 14 is provided with a storage inlet communicating with the storage space, and the storage inlet is connected to the outlet. Since the storage inlet and outlet are connected, under the action of the airflow formed by the fan blade assembly 13, the dust enters the storage space of the storage component 14 from the outlet along the airflow direction, thus achieving efficient dust collection.

[0066] In some specific embodiments of this application, the cleaning device 10 includes: a housing 11, a brush wheel 12, a fan blade assembly 13, a storage component 14, and a rotating shaft 15. At least a portion of the rotating shaft 15 is disposed within the housing 11. The brush wheel 12 and the fan blade assembly 13 are coaxially disposed with the rotating shaft 15 and fixed in the portion of the rotating shaft 15 located within the housing 11, wherein the fan blade assembly 13 is fixed near the storage component 14.

[0067] In the specific embodiments described above, multiple brush wheels 12 are provided.

[0068] In the specific embodiments described above, the fan blade assembly 13 includes a plurality of fan blades.

[0069] In some embodiments of this application, the cleaning device 10 further includes a first bearing 16, which includes a first inner ring and a first outer ring that are rotatable relative to each other. The first outer ring is connected to the housing 11, and the first inner ring is connected to the rotating shaft 15. That is, the first outer ring is fixedly connected to the housing 11, and the first inner ring is fixedly connected to the rotating shaft 15, and the first inner ring rotates synchronously with the rotating shaft 15.

[0070] Thus, the first bearing 16 provides precise radial support for the rotating shaft 15, ensuring its stability during high-speed rotation, reducing wobbling and eccentricity, and effectively preventing uneven cleaning or collisions between the brush wheel 12 and the track 21 caused by unstable rotation. Furthermore, the rolling friction of the bearing is much less than the sliding friction, which significantly reduces the frictional resistance between the rotating shaft 15 and the housing 11, reducing energy loss and improving the energy efficiency of the cleaning device 10.

[0071] In some embodiments of this application, the cleaning device 10 further includes: a second bearing 17, which is disposed at opposite ends of the rotating shaft 15 to the first bearing 16; the second bearing 17 includes a second inner ring and a second outer ring that are rotatable relative to each other, the second outer ring being connected to the housing 11 and the second inner ring being connected to the rotating shaft 15.

[0072] Since the first bearing 16 and the second bearing 17 are respectively located at opposite ends of the rotating shaft 15, they form a two-end support structure for the rotating shaft 15. In this way, the first bearing 16 and the second bearing 17 can effectively withstand various loads on the rotating shaft 15, preventing the rotating shaft 15 from shifting or tilting, thereby ensuring that the brush wheel 12 always maintains good contact with the track 21 of the slip ring 20, improving the cleaning effect. In addition, the cooperation between the second bearing 17 and the first bearing 16 makes the rotation of the rotating shaft 15 smoother, reducing vibration and noise generated during rotation, and extending the service life of the entire cleaning device 10.

[0073] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
