Description

Technical Field

[0001] The present invention relates to the technical field of living tools, and in particular to a cleaning device. Background Art

[0002] After using cups and other utensils, they are cleaned with a cup brush.

[0003] Technicians in this field have discovered that different sizes of utensils to be cleaned require cup brushes with corresponding apertures for cleaning. However, in households, cup brushes are not necessarily available in all sizes. Therefore, in many cases, users use inappropriate cup brushes to clean utensils. When using a cup brush that does not match the size of the vessel for cleaning, the cup brush is prone to eccentricity, making the cleaning process particularly laborious and the cleaning effect poor. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, the present invention provides a cleaning device.

[0006] In view of this, the present invention provides a cleaning device, comprising: a plurality of bearing parts; a rod body; and a connecting structure, wherein the connecting structure is movably connected to the rod body and the bearing parts so that the bearing parts can be moved closer to or away from the rod body.

[0007] The technical solution of the present application proposes a cleaning device, wherein the bearing part is not fixed, and its position can be changed relative to the rod body. When the bearing part approaches the rod body or moves away from the rod body, the cleanable caliber of the cleaning device will change.

[0008] Since the cleaning diameter of the cleaning device can be changed, it can clean cups of various sizes and adapt to various usage scenarios. Users do not need to purchase cup brushes of various sizes.

[0009] Specifically, the cleaning device proposed in the present application includes a rod body, a connection structure connecting the rod body and a bearing part, wherein the connection structure serves to limit the range in which the bearing part can move relative to the rod body.

[0010] Since the caliber of the cleaning device that can be cleaned can be changed, the caliber can be consistent with the caliber of the cup body that needs to be cleaned. Therefore, in the process of using the cleaning device to clean the cup body that needs to be cleaned, the probability of eccentricity is low. Therefore, the cleaning device proposed in this application has the characteristic of saving labor during the cleaning process.

[0011] At the same time, the caliber of the cleaning device that can be cleaned can be consistent with the caliber of the cup body that needs to be cleaned. Therefore, the supporting part can fit tightly with the inner wall of the cup body that needs to be cleaned. During the cleaning process, food residues on the inner wall of the cup body are cleaned off, ensuring the cleaning effect.

[0012] In addition, the cleaning equipment defined in this application also has the following additional technical features, including:

[0013] In the above technical solution, a plurality of bearing parts are assembled to obtain a main body, and the cleaning device further comprises: bristles, which are spirally wound around the axis of the main body on the peripheral side of the main body to form an Archimedean screw pattern.

[0014] In this technical solution, the bristles are spirally wound around the axis of the body on the peripheral side of the body to form an Archimedean screw pattern, so that the cleaning device does not need to provide a large torque during the cleaning process, making the cleaning device labor-saving.

[0015] In addition, when the bristles fit the inner wall of the cup body to be cleaned, the turbulent kinetic energy and wall velocity of the inner wall of the cup body to be cleaned are relatively large, thereby ensuring the cleaning effect.

[0016] In any of the above technical solutions, the cleaning device further includes: a driving assembly, which is connected to the rod body and drives the rod body to rotate.

[0017] In this technical solution, when the driving assembly can drive the rod body to rotate, the user does not need to manually drive the rod body to rotate, which improves the convenience of the user using the cleaning device to clean the cup body and improves the efficiency of cleaning the cup body.

[0018] It is worth pointing out that when the driving assembly drives the rod body to rotate, the bearing part is affected by the centrifugal force and moves away from the rod body, fitting against the inner wall of the cup body that needs to be cleaned. In this process, the automatic adjustment of the cleanable caliber is achieved, ensuring that the bristles on the bearing part fit closely against the inner wall of the cup body that needs to be cleaned, thereby ensuring the cleaning effect.

[0019] In the above technical solution, the rod body has an inner cavity and a drainage hole for connecting the inner cavity and the outer cavity; a closing member is used to close the drainage hole, wherein the closing member closes the drainage hole based on the rod body stopping rotation, and the closing member stops closing the drainage hole based on the rod body rotating.

[0020] In this technical solution, the structure of the rod body is specifically defined. Specifically, the rod body is a hollow structure, a cavity is formed in the rod body, and a drainage hole is formed on the rod body, wherein the setting of the drainage hole can discharge the liquid in the inner cavity from the inner cavity, and correspondingly, a sealing member is also used in conjunction with the drainage hole, wherein the sealing member is used to control whether the drainage hole discharges the liquid. Specifically, when the liquid is not required to be discharged through the drainage hole, the sealing member is used to seal it, and when the liquid is required to be discharged from the drainage hole, the sealing effect of the sealing member on it is cancelled.

[0021] By using the above design, the user can inject cleaning liquid into the inner cavity, so that when the cleaning device is used to clean the cup body to be cleaned, the liquid discharge hole is controlled to discharge the liquid outward. In this process, the user can clean the cup body with one hand, without the need for the user to manually take liquid to clean the cup body, which improves the convenience of the cleaning device during use.

[0022] In any of the above technical solutions, the cleaning device also includes: a first elastic member, one end of the first elastic member is connected to the inner wall of the inner cavity, and the other end of the first elastic member is connected to the closing member. Based on the rod body stopping rotation, the closing member closes the drainage hole under the pulling force of the first elastic member.

[0023] In this technical solution, it is specifically defined how the closure member and the drain hole cooperate with each other. Specifically, the technical solution of the present application introduces a first elastic member, wherein the first elastic member is used to provide a pulling force, under which the closure member can close the drain hole. When the cleaning device is running and the cup body to be cleaned is cleaned, the closure member will rotate along the axial direction of the rod body. When the centrifugal force exerted on the closure member is greater than the pulling force provided by the first elastic member, the closure member will cancel the sealing effect on the drain hole, so that the cleaning liquid in the inner cavity is discharged through the drain hole.

[0024] In this process, the control of the closure can be combined with the rotation of the bearing part, and there is no need to set up a separate controller for the use of the closure, which reduces the occupation of the inner cavity space by components and also facilitates reducing the manufacturing cost of the cleaning equipment.

[0025] In addition, the control of the closing member is combined with the rotation of the bearing part. The closing member can cancel the sealing of the drainage hole only after the rod body rotates, and the closing member can close the drainage hole when the rod body stops rotating. It can be understood that the closing member can cancel the sealing of the drainage hole only when the rod body rotates. Therefore, it is ensured that the drainage hole can be effectively closed when the cleaning equipment is not in use, thereby reducing the leakage of the cleaning liquid.

[0026] In any of the above technical solutions, the cleaning liquid can be a cleaning agent or water.

[0027] In any of the above technical solutions, the cleaning device further includes: a handle, the handle is connected to the rod body, the handle is provided with a first cavity, the first cavity is used to store the cleaning liquid and supply the liquid to the inner cavity.

[0028] In this technical solution, it is specifically defined that the cleaning device also includes a handle, wherein the handle is connected to the rod body so that the user can use the cleaning device by holding the handle. In addition, the handle is defined to be provided with a first cavity so that the first cavity can be used to store cleaning liquid to replenish the liquid into the inner cavity, thereby avoiding the situation where the volume of the inner cavity is too small to store more cleaning liquid due to the volume limitation of the rod body, and ultimately there is a situation in which, during the cleaning process using the cleaning device, there is insufficient cleaning liquid in the inner cavity, and cleaning needs to be stopped and the cleaning liquid needs to be replenished a second time.

[0029] By providing the first cavity in the handle, the occurrence of the above situation is effectively reduced, thereby improving the reliability of the cleaning device during use.

[0030] In any of the above technical solutions, the cleaning device further includes: a pump body, which is located in the first cavity and is used to supply liquid to the inner cavity.

[0031] In this technical solution, the cleaning equipment is also provided with a pump body, wherein the pump body is used to inject the liquid in the first cavity into the inner cavity to ensure timely replenishment of the cleaning liquid and avoid the situation where the cleaning liquid in the first cavity cannot be replenished to the inner cavity in time due to excessive viscosity of the cleaning liquid. By providing the pump body, the stable operation of the cleaning equipment is ensured.

[0032] In any of the above technical solutions, it also includes: the handle is provided with a second cavity, and the driving component is located in the second cavity.

[0033] In this technical solution, the handle is also provided with a second cavity, wherein the driving assembly is arranged in the second cavity to avoid the driving assembly being exposed to the outside and affecting the appearance of the cleaning device. At the same time, arranging the driving assembly in the second cavity can also ensure that the driving assembly will not be disturbed by the bearing part and the connecting structure during the use of the cleaning device, thereby ensuring the stable operation of the driving assembly.

[0034] In any of the above technical solutions, the handle includes: an upper handle; a lower handle, the lower handle is connected to the rod body, and the lower handle has a first cavity; the upper handle and the lower handle enclose and define a second cavity.

[0035] In this technical solution, the handle is divided into two parts, an upper handle and a lower handle, and it is specifically defined that the second cavity is enclosed by the upper handle and the lower handle, so that when assembling the cleaning device, it is easy to install the drive component on the handle, thereby improving assembly efficiency.

[0036] In any of the above technical solutions, it also includes: a coupling, which connects the drive assembly and the rod body.

[0037] In this technical solution, the connection method between the drive assembly and the rod body is specifically defined, and a coupling connection scheme is adopted to avoid directly connecting the rod body with the rotor of the drive assembly, so that the cleaning device can be divided into two parts, namely, a cleaning assembly consisting of a brush structure, a rod body and a connecting structure, and a holding part consisting of a handle and a drive assembly. Since the rod body and the drive assembly are connected by a coupling, the cleaning assembly and the holding part can be transported as an independent accessory before the cleaning device is assembled, which effectively reduces the packaging size of the cleaning equipment and provides convenience for transportation.

[0038] In any of the above technical solutions, the driving assembly includes: a motor, which is connected to the coupling and is used to drive the coupling to rotate; and an energy storage device, which is used to supply power to the motor to drive the motor to operate.

[0039] In this technical solution, the driving component includes a motor and an energy storage device, wherein the energy storage device can supply power to the motor to drive the motor to rotate. During this process, the cleaning device does not need to be equipped with a power supply cable. Therefore, the use scope of the cleaning device is no longer limited by the power supply cable, thereby improving the portability of the cleaning device.

[0040] In any of the above technical solutions, it also includes: a control device, which is connected to the driving component, and the control device is used to: receive a start signal, control the driving component to operate, so as to drive the rod body to rotate.

[0041] In this technical solution, the cleaning device also includes a control device, wherein the operation of the driving component is controlled based on the connection relationship between the control device and the driving component. Specifically, when the control device receives an on signal, the driving component is controlled to operate, so that during the operation of the driving component, the driving rod body is driven to rotate, and then the bearing part is driven to rotate with the rod body as the rotation axis, so as to achieve cleaning of the cup body that needs to be cleaned.

[0042] In any of the above technical solutions, the cleaning device also includes: a display device, which is located on the handle and is used to display the operating information of the driving component.

[0043] In this technical solution, the cleaning device also includes a display device, wherein the display device can display the operating information of the drive component so that the user can know the operating status of the cleaning device. If adjustment is needed, the operating status of the drive component is adjusted to adapt to the cleaning scenarios of cups of different calibers.

[0044] In any of the above technical solutions, the operating information includes: at least one of the operating gear, the operating speed, and the remaining power information of the energy storage device.

[0045] In any of the above technical solutions, it also includes: a rebound structure, one end of the rebound structure is connected to the brush structure or the connecting structure, and the other end of the rebound structure is connected to the rod body.

[0046] In this technical solution, a rebound structure is provided so that the brush structure can return to the default position after the cleaning device finishes cleaning the cup body, thereby avoiding the situation where the cleaning device cannot be removed when the cleaning device is used to clean a cup body with a small opening and a large cup cavity.

DETAILED DESCRIPTION

[0068] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0069] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0070] Embodiment 1

[0071] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to the first aspect of the present invention, the present invention provides a cleaning device 100, including: a plurality of bearing parts 302; a rod body 200; a connecting structure 400, the connecting structure 400 is movably connected to the rod body 200 and the bearing part 302, so that the bearing part 302 can move closer to or away from the rod body 200.

[0072] The embodiment of the present application proposes a cleaning device 100, wherein the bearing portion 302 is not fixed, and its position can be changed relative to the rod body 200. When the bearing portion 302 approaches the rod body 200 or moves away from the rod body 200, the cleanable caliber of the cleaning device 100 will change.

[0073] Since the caliber of the cleaning device 100 can be changed, the cleaning device 100 can clean cups of various sizes. The cleaning device 100 can be adapted to various usage scenarios, and users do not need to purchase cup brushes of various sizes.

[0074] Specifically, the cleaning device 100 proposed in the present application includes a rod body 200 and a connection structure 400 connecting the rod body 200 and the bearing portion 302 , wherein the connection structure 400 serves to limit the range within which the bearing portion 302 can move relative to the rod body 200 .

[0075] Since the caliber of the cleanable area of ​​the cleaning device 100 can be changed, the caliber can be consistent with the caliber of the cup body to be cleaned. Therefore, in the process of using the cleaning device 100 to clean the cup body to be cleaned, the probability of eccentricity is low. Therefore, the cleaning device 100 proposed in the present application has the characteristic of saving labor during the cleaning process.

[0076] At the same time, the caliber of the cleaning device 100 can be consistent with the caliber of the cup body to be cleaned. Therefore, the supporting part 302 can fit tightly with the inner wall of the cup body to be cleaned. During the cleaning process, food residues on the inner wall of the cup body are cleaned off to ensure the cleaning effect.

[0077] Embodiment 2

[0078] In one embodiment, a plurality of bearing parts are assembled to form a main body, and the cleaning device 100 further includes bristles, which are spirally wound around the axis of the main body on the peripheral side of the main body to form an Archimedean screw pattern.

[0079] In this embodiment, the bristles are spirally wound around the axis of the body and on the peripheral side of the body to form an Archimedean screw pattern, so that the cleaning device does not need to provide a large torque during the cleaning process, making the cleaning device labor-saving.

[0080] In addition, when the bristles fit the inner wall of the cup body to be cleaned, the turbulent kinetic energy and wall velocity of the inner wall of the cup body to be cleaned are relatively large, thereby ensuring the cleaning effect.

[0081] Embodiment 3

[0082] In one embodiment, the cleaning device 100 further includes: a driving assembly 500 , which is connected to the rod body 200 and drives the rod body 200 to rotate.

[0083] When the driving assembly 500 can drive the rod body 200 to rotate, the user does not need to manually drive the rod body 200 to rotate, which improves the convenience of the user using the cleaning device 100 to clean the cup body and improves the efficiency of cleaning the cup body.

[0084] It is worth pointing out that when the driving assembly 500 drives the rod body 200 to rotate, the bearing part 302 is affected by the centrifugal force and moves away from the rod body 200, fitting against the inner wall of the cup body that needs to be cleaned. In this process, the automatic adjustment of the cleanable caliber is achieved, ensuring that the bristles 304 on the bearing part 302 fit closely against the inner wall of the cup body that needs to be cleaned, thereby ensuring the cleaning effect.

[0085] In one embodiment, the rod body 200 is a telescopic rod.

[0086] In this embodiment, the rod body 200 is a telescopic rod. Therefore, during the actual use of the cleaning device 100, the depth of the cleaning device 100 inserted into the cup cavity can be adjusted according to actual needs to be suitable for cleaning cups of different depths. In this process, the applicability of the cleaning device 100 is improved.

[0087] Embodiment 4

[0088] In one embodiment, if Figure 2 As shown, the rod body 200 has an inner cavity 202 and a drainage hole 204 for connecting the inner cavity 202 with the outside; a closing member 206, and the closing member 206 is used to close the drainage hole 204, wherein the closing member 206 closes the drainage hole 204 based on the rod body 200 stopping rotation, and the closing member 206 stops closing the drainage hole 204 based on the rod body 200 rotating.

[0089] In this embodiment, the structure of the rod body 200 is specifically defined. Specifically, the rod body 200 is a hollow structure, a cavity is formed in the rod body 200, and a drainage hole 204 is formed on the rod body 200, wherein the setting of the drainage hole 204 can discharge the liquid in the inner cavity 202 from the inner cavity 202, and correspondingly, a sealing member 206 is also used in conjunction with the drainage hole 204, wherein the sealing member 206 is used to control whether the drainage hole 204 discharges the liquid. Specifically, when the liquid is not required to be discharged through the drainage hole 204, the sealing member 206 is used to seal it, and when the liquid is required to be discharged from the drainage hole 204, the sealing effect of the sealing member 206 on it is cancelled.

[0090] By using the above design, the user can inject cleaning liquid into the inner cavity 202, so that when using the cleaning device 100 to clean the cup body that needs to be cleaned, the drainage hole 204 can be controlled to discharge the liquid outward. In this process, the user can clean the cup body with one hand, and the user does not need to manually take liquid to clean the cup body, which improves the convenience of the cleaning device 100 during use.

[0091] In one embodiment, if Figure 3 As shown, the cleaning device 100 also includes: a first elastic member 208, one end of the first elastic member 208 is connected to the inner wall of the inner cavity 202, and the other end of the first elastic member 208 is connected to the closing member 206. Based on the rod body 200 stopping rotation, the closing member 206 closes the drainage hole 204 under the pulling force of the first elastic member 208.

[0092] In this embodiment, how the closure member 206 and the drainage hole 204 cooperate with each other is specifically defined. Specifically, the embodiment of the present application introduces a first elastic member 208, wherein the first elastic member 208 is used to provide a pulling force, under which the closure member 206 can close the drainage hole 204. When the cleaning device 100 is running and the cup body to be cleaned is cleaned, the closure member 206 will rotate along the axial direction of the rod body 200. When the centrifugal force exerted on the closure member 206 is greater than the pulling force provided by the first elastic member 208, the closure member 206 will cancel the sealing effect on the drainage hole 204, so that the cleaning liquid in the inner cavity 202 is discharged through the drainage hole 204.

[0093] During this process, the control of the closure 206 can be combined with the rotation of the supporting part 302, and there is no need to set up a separate controller for the use of the closure 206, which reduces the space occupied by components in the inner cavity 202 and also facilitates reducing the manufacturing cost of the cleaning equipment 100.

[0094] In addition, the control of the sealing member 206 is combined with the rotation of the bearing portion 302. The sealing member 206 can cancel the sealing of the drainage hole 204 only after the rod body 200 rotates, and the sealing member 206 can seal the drainage hole 204 when the rod body 200 stops rotating. It can be understood that the sealing member 206 can cancel the sealing of the drainage hole 204 only when the rod body 200 rotates. Therefore, it is ensured that when the cleaning device 100 is not in use, the drainage hole 204 can be effectively closed to reduce the leakage of the cleaning liquid.

[0095] In any of the above embodiments, the cleaning liquid may be a cleaning agent or water.

[0098] In this embodiment, it is specifically defined that the cleaning device 100 also includes a handle 600, wherein the handle 600 is connected to the rod body 200 so that the user can use the cleaning device 100 by holding the handle 600. In addition, the handle 600 is defined to be provided with a first cavity 602 so that the first cavity 602 can be used to store cleaning liquid to replenish the liquid into the inner cavity 202, thereby avoiding the situation where the volume of the inner cavity 202 is too small to store more cleaning liquid due to the volume limitation of the rod body 200, and ultimately, during the cleaning process using the cleaning device 100, there is insufficient cleaning liquid in the inner cavity 202, and it is necessary to stop cleaning and replenish the cleaning liquid for a second time.

[0099] By providing the first cavity 602 in the handle 600, the occurrence of the above situation is effectively reduced, thereby improving the reliability of the cleaning device 100 during use.

At the same time, arranging the driving component 500 in the second cavity 606 can also ensure that the driving component 500 will not be disturbed by the bearing part 302 and the connecting structure 400 during the use of the cleaning device 100, thereby ensuring the stable operation of the driving component 500.

[0105] In one embodiment, the handle 600 includes: an upper handle 6002; a lower handle 6004, the lower handle 6004 is connected to the rod body 200, and the lower handle 6004 has a first cavity 602; the upper handle 6002 and the lower handle 6004 enclose and define a second cavity 606.

[0106] In this embodiment, the handle 600 is divided into two parts, an upper handle 6002 and a lower handle 6004, and the second cavity 606 is specifically defined as being enclosed by the upper handle 6002 and the lower handle 6004, so that when assembling the cleaning device 100, it is convenient to install the drive assembly 500 on the handle 600, thereby improving assembly efficiency.

[0109] In this embodiment, the connection method between the drive assembly 500 and the rod body 200 is specifically defined, and a connection scheme of a coupling 700 is adopted to avoid directly connecting the rod body 200 with the rotor of the drive assembly 500, so that the cleaning device 100 can be divided into two parts, namely, a cleaning assembly consisting of a brush structure 300, a rod body 200 and a connecting structure 400, and a holding part consisting of a handle 600 and a drive assembly 500. Since the rod body 200 and the drive assembly 500 are connected by a coupling 700, before the cleaning device 100 is assembled, the cleaning assembly and the holding part can be transported as an independent accessory, which effectively reduces the packaging size of the cleaning device 100 and provides convenience for transportation.

[0110] Embodiment 8

[0111] In one embodiment, if Figure 4 As shown, the driving assembly 500 includes: a motor 502, which is connected to the coupling 700 and is used to drive the coupling 700 to rotate; and an energy storage device 504, which is used to supply power to the motor 502 to drive the motor 502 to operate.

[0112] In this embodiment, the driving component 500 includes a motor 502 and an energy storage device 504, wherein the energy storage device 504 can supply power to the motor 502 to drive the motor 502 to rotate. During this process, the cleaning device 100 does not need to be equipped with a power supply cable. Therefore, the use range of the cleaning device 100 is no longer limited by the power supply cable, thereby improving the portability of the cleaning device 100.

[0113] Embodiment 9

[0114] In one embodiment, if Figure 4 As shown, the cleaning device 100 further includes: a control device 800, which is connected to the driving assembly 500, and the control device 800 is used to: receive a start signal, control the driving assembly 500 to operate, so as to drive the rod body 200 to rotate.

[0115] In this embodiment, the cleaning device 100 also includes a control device 800, wherein the operation of the driving component 500 is controlled based on the connection relationship between the control device 800 and the driving component 500. Specifically, when the control device 800 receives a start signal, the driving component 500 is controlled to operate, so that during the operation of the driving component 500, the rod body 200 is driven to rotate, and then the brush structure 300 is driven to rotate with the rod body 200 as the rotation axis, so as to achieve the cleaning of the cup body that needs to be cleaned.

[0116] In any of the above embodiments, it also includes: a display device 900, which is located on the handle 600 and is used to display the operating information of the driving component 500.

[0117] In this embodiment, the cleaning device 100 also includes a display device 900, wherein the display device 900 can display the operating information of the driving component 500 so that the user can know the operating status of the cleaning device 100. When adjustment is needed, the operating status of the driving component 500 is adjusted to adapt to the cleaning scenarios of cups of different calibers.

[0118] In any of the above embodiments, the operation information includes at least one of: an operation gear, an operation speed, and information on the remaining power of the energy storage device 504 .

[0119] Embodiment 10

[0120] In one embodiment, if Figure 4As shown, the cleaning device 100 further includes: a rebound structure 1000 , one end of the rebound structure 1000 is connected to the bearing portion 302 or the connecting structure 400 , and the other end of the rebound structure 1000 is connected to the rod body 200 .

[0121] In this embodiment, a rebound structure 1000 is provided so that the supporting portion 302 can return to the default position after the cleaning device 100 finishes cleaning the cup body, thereby avoiding the situation where the cleaning device 100 cannot be taken out when the cleaning device 100 is used to clean a cup body with a small opening and a large cup cavity.

[0122] In this process, the reliability of the use of the cleaning device 100 is ensured.

[0123] In any of the above embodiments, the resilient structure 1000 includes a second elastic member.

[0124] In this embodiment, the rebound structure 1000 includes a second elastic member, which has a simple structure and strong stability.

[0125] Embodiment 11

[0126] like Figure 5 As shown, in any of the above embodiments, the brush structure 300 is composed of a plurality of bearing parts 302 and bristles 304 located on the bearing parts, wherein the plurality of bearing parts 302 are assembled to form a main body, and the bristles 304 are spirally coiled around the axis of the main body on the peripheral side of the main body. Specifically, the brush structure 300 is sleeved on the rod body 200.

[0127] In this embodiment, the brush structure 300 includes a main body formed by assembling a plurality of bearing parts 302 and bristles 304 arranged on the main body. It can be understood that the brush structure 300 is a combined structure. Therefore, in the process of the bearing part 302 approaching or moving away from the rod body 200, the gap between the plurality of bearing parts 302 can be increased or decreased to achieve a change in the caliber that can be cleaned by the cleaning device 100.

[0128] Since the bristles 304 can only clean the inner wall of the cup body when in contact with it, the bristles 304 need to apply force to the inner wall of the cup body when in contact. The bristles 304 are made of a relatively soft material and the force they transmit is limited. The main body formed by assembling multiple bearing parts 302 is used to provide support for the bristles 304, so as to ensure that the brush structure 300 can provide a sufficiently large force to the inner wall of the cup body to ensure the cleaning effect.

[0129] In addition, the bristles 304 are spirally coiled around the axis of the main body on the peripheral surface of the main body, which can provide greater turbulent kinetic energy and wall velocity. The greater turbulent kinetic energy and wall velocity are positively correlated with the cleaning effect of the inner wall of the cup body. Therefore, the cleaning effect can be improved by limiting the coiling method of the bristles 304.

[0130] In any of the above embodiments, there are multiple connection structures 400 , and one or more connection structures 400 are connected to the same bearing portion 302 .

[0131] In this embodiment, one or more connection structures 400 are connected to the same bearing portion 302, and multiple connection structures 400 are connected to the same bearing portion 302, which reduces the probability of separation between the bearing portion 302 and the rod body 200 and ensures the stability of the connection between the bearing portion 302 and the rod body 200.

[0132] In addition, since multiple connection structures 400 are connected to the same supporting part 302, the posture of the supporting part 302 is constrained by the multiple connection structures 400. When the cleaning device 100 is in use, the posture of the supporting part 302 is relatively stable, reducing the probability of its deviation.

[0133] In any of the above embodiments, any connecting structure 400 includes: a first sliding portion 402, which is sleeved on the rod body 200 and slides along the axial direction of the rod body 200; a first connecting rod 404, one end of the first connecting rod 404 is movably connected to the first sliding portion 402, and the other end of the first connecting rod 404 is connected to the bearing portion 302.

[0134] In this embodiment, the connecting structure 400 includes a first sliding portion 402 and a first connecting rod 404, wherein the first sliding portion 402 is provided to transmit the rotation of the rod body 200 to the first connecting rod 404, so that when the first connecting rod 404 moves, it drives the brush structure 300 to operate, and finally when the rod body 200 rotates, it drives the brush structure 300 to rotate with the rod body 200 as the rotation axis, thereby achieving the cleaning of the inner wall of the cup body.

[0135] By limiting the axial sliding of the first sliding part 402 and the rod body 200, it is ensured that the first sliding part 402 can drive the first connecting rod 404 and the brush structure 300 to rotate with the rod body 200 as the rotation axis, thereby providing driving force for the rotation of the brush structure 300. At the same time, the user can adjust the relative position of the brush structure 300 on the rod body 200 by adjusting the sliding position of the first sliding part 402 on the rod body 200, so that the cleaning device 100 can adapt to cups of various depths, thereby improving the adaptability of the cleaning device 100 to actual usage scenarios.

[0136] In addition, the use of the first connecting rod 404 serves to increase or decrease the caliber of the cleanable opening of the brush structure 300, thereby ensuring that the cleaning device 100 can be adapted to cups of various calibers.

[0137] In any of the above embodiments, the connection structure 400 also includes: a first connection part 406, one end of the first connection part 406 is connected to the other end of the first connecting rod 404, and the other end of the first connection part 406 is movably connected to the bearing part 302 to enable the bearing part 302 to rotate relative to the first connecting rod 404.

[0138] In this embodiment, the connecting structure 400 also includes a first connecting portion 406, wherein the other end of the first connecting rod 404 is connected to the bearing portion 302 via the first connecting portion 406. During this process, the bearing portion 302 can rotate relative to the first connecting rod 404, so that after the brush structure 300 adjusts its own washable caliber through the first connecting rod 404, the bearing portion 302 can be tightly attached to the inner wall of the cup body to be cleaned, thereby ensuring the cleaning effect.

[0139] In any of the above embodiments, the first connection portion 406 is a spherical connection.

[0140] In any of the above embodiments, the connecting structure 400 includes: a second sliding portion 408, which is sleeved on the rod body 200; a second connecting rod 410, one end of which is movably connected to the second sliding portion 408, and the other end of which is connected to the bearing portion 302.

[0141] In this embodiment, the connecting structure 400 also has a second sliding portion 408 and a second connecting rod 410 corresponding to the first sliding portion 402 and the first connecting rod 404, wherein the setting of the second sliding portion 408 and the second connecting rod 410 serves to balance the tension or pressure on the first sliding portion 402 and the first connecting rod 404, so that when in use, the forces on the first connecting rod 404 and the second connecting rod 410 are relatively uniform, thereby reducing the probability of damage to the first sliding portion 402 and the first connecting rod 404 under strong load.

[0142] In addition, the second sliding portion 408 and the second connecting rod 410 can also stabilize the posture of the bearing portion 302, thereby reducing the occurrence of large fluctuations of the bearing portion 302 during operation.

[0143] In any of the above embodiments, the connecting structure 400 also includes: a second connecting portion 412, one end of the second connecting portion 412 is connected to the other end of the second connecting rod 410, and the other end of the second connecting portion 412 is movably connected to the bearing portion 302 to enable the bearing portion 302 to rotate relative to the second connecting rod 410.

[0144] In this embodiment, the connecting structure 400 also includes a second connecting portion 412, wherein the other end of the second connecting rod 410 is connected to the bearing portion 302 via the second connecting portion 412. During this process, the bearing portion 302 can rotate relative to the second connecting rod 410, so that after the brush structure 300 adjusts its own washable caliber through the second connecting rod 410, the bearing portion 302 can be tightly attached to the inner wall of the cup body to be cleaned, thereby ensuring the cleaning effect.

[0145] In any of the above embodiments, the plurality of bearing portions 302 are evenly arranged along the circumference of the rod body 200 .

[0146] In this embodiment, the distribution positions of multiple bearing parts 302 are specifically defined. By limiting the bearing parts 302 to be evenly arranged along the circumference of the rod body 200, it is ensured that when the rod body 200 rotates, the tension at various circumferential positions of the rod body 200 is similar, ensuring that the cleaning component can stably rotate about the axis of the rod body 200. At the same time, it can also reduce the probability of the cleaning component colliding with the inner wall of the cup body to be cleaned during rotation, thereby improving the reliability of the cleaning component during operation.

[0147] In any of the above embodiments, one end of the rod body 200 away from the brush structure 300 has a through hole, wherein the through hole is arranged along the radial direction of the rod body 200 .

[0148] In this embodiment, a through hole is provided on the rod body 200 so as to fix a driving assembly 500 for providing driving force to the cleaning assembly to drive the rod body 200 to rotate.

[0149] In any of the above embodiments, the bearing portion 302 is an arc plate.

[0150] In this embodiment, the shape of the bearing portion 302 is specifically defined. Specifically, in the embodiment of the present application, the bearing portion 302 is defined as an arc plate, so that a main body obtained by splicing a plurality of bearing portions 302 can be a cylindrical shape. At this time, the bristles 304 are arranged on the cylindrical main body, which can ensure that the bristles 304 at different positions have the same static pressure, thereby reducing the influence of uneven static pressure distribution on the cleaning effect.

[0151] In any of the above embodiments, one of a groove and a protrusion is provided in the axial direction of the rod body 200 , and the other of a groove and a protrusion is provided on the first sliding portion 402 .

[0152] In this embodiment, the connection method between the first sliding part 402 and the rod body 200 is specifically defined. Specifically, the matching method of the groove and the protrusion is adopted to limit the sliding direction of the first sliding part 402 on the rod body 200. In this process, the stability of the connection between the first sliding part 402 and the connecting rod is ensured.

[0153] Embodiment 12

[0154] In one embodiment, if Figure 6 As shown, the bristles 304 are spirally wound around the axis of the body on the peripheral side of the body to form an Archimedean screw pattern, wherein the bearing portion 302 and the bristles 304 form a brush structure 300 .

[0155] After theoretical and simulation analysis, the brush structure 300 proposed in the present application can improve the cleaning effect. At the same time, the cleaning device 100 using the above-mentioned brush structure 300 does not require a driving component 500 with a large torque, which is more labor-saving than the existing brush structure. Therefore, the probability of damage to the driving component 500 due to excessive load can be reduced.

[0156] Specifically, from the perspective of fluid, in order to clean the cup, the turbulent kinetic energy and wall velocity should be as large as possible, so that the load on the brush is as small as possible, that is, the static pressure on the cup surface should be as small as possible. From a qualitative perspective, Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown, through simulation comparative analysis, it can be known that the turbulent kinetic energy and velocity cloud diagram of the brush structure 300 defined in the present application are greater than those of the brush structure in the relevant embodiments, that is, the turbulent kinetic energy and the cup wall velocity when the brush structure in the present application is used to brush the cup are greater than the turbulent kinetic energy and the cup wall velocity when the brush structure in the relevant embodiments is used to brush the cup. At the same time, the static pressure on the wall when the brush structure in the relevant embodiments brushes the cup is higher than the static pressure when the brush structure 300 in the present application is used to brush the cup. Based on this, it can be qualitatively analyzed that the brush structure 300 defined in the present application has a higher cleaning effect on the cup than the existing brush.

[0157] In addition, by limiting the main body to be composed of multiple supporting parts 302, the main body can be adjusted according to the size of the cup body actually cleaned, so that the same brush structure 300 can meet the cleaning needs of cups of different sizes, overcoming the disadvantage that the existing brush structure 300 can only be used in a single scenario.

[0158] In the above embodiment, in the axial direction of the body, the Archimedean screw pattern extends from one end of the body to the other end of the body.

[0159] In this embodiment, the axial projection of the bristles 304 distributed in an Archimedean screw pattern on the main body is the same as the axial length of the main body. Therefore, the brush structure 300 has a maximum cleaning length. When the brush structure 300 is extended into the cup body to be cleaned, the cleaning area of ​​the cup wall to be cleaned is maximized, thereby improving the cleaning efficiency.

[0160] In any of the above embodiments, the bristles 304 are divided into a plurality of bristle clusters, and the plurality of bristle clusters are arranged at intervals.

[0161] In this embodiment, the bristles 304 are divided into a plurality of bristle clusters that are spaced apart so that there are gaps between different bristle clusters. The gaps can accommodate food residues cleaned from the cup by the bristles 304, thereby reducing the food residues from being trapped in the bristle clusters, which would reduce the cleaning effect of the bristle clusters on the cup.

[0162] In addition, there are gaps between different bristle clusters. Since the cleaned food residues are stored in the gaps, it is possible to prevent the cleaned food residues from being coated on the cleaned cup body by the bristles 304 again, causing the secondary attachment of the cleaned food residues. In the embodiments of the present application, the above situation is overcome and the cleaning effect is ensured.

[0163] In any of the above embodiments, a plurality of bristle clusters constitute a bristle group, and any bristle group corresponds to an Archimedean screw pattern.

[0164] In this embodiment, multiple bristle clusters are grouped and divided to form multiple Archimedean thread patterns, thereby increasing the number of Archimedean thread patterns in the brush structure 300. When cleaning a cup that needs to be cleaned, multiple brush groups with Archimedean thread patterns can clean the cup at the same time, thereby improving the cleaning efficiency of the cup.

[0165] In any of the above embodiments, the plurality of bristle groups are arranged at intervals.

[0166] In this embodiment, different bristle groups are spaced apart, that is, there are gaps between different Archimedean screw-shaped patterns, so that food residues cleaned by the brush structure 300 can be stored in the gaps between different Archimedean screw-shaped patterns, thereby preventing the cleaned food residues from being coated on the cleaned cup body by the bristles 304 again, causing the secondary attachment of the cleaned food residues, thereby ensuring the cleaning effect.

[0167] In any of the above embodiments, if Figure 5 As shown, it also includes: a top cover 306, which is arranged on one end of the body, and bristles 304 are arranged on a side of the top cover 306 away from the body.

[0168] In this embodiment, it is defined that the brush structure 300 also has a top cover 306 with bristles 304 and the setting position of the bristles 304. In this embodiment, by setting the top cover 306 with bristles 304, when the brush structure 300 extends into the cup body to be cleaned, the bottom of the cup body can be directly cleaned, and the user does not need to use additional equipment to clean the bottom of the cup. In addition, since the top cover 306 is set at one end of the body, the bottom of the cup is also cleaned in the process of the body rotating to clean the cup wall, which simplifies the cleaning steps and improves the cleaning effect.

[0169] In any of the above embodiments, the orientation of the bristles 304 on the top cover 306 is perpendicular to the orientation of the bristles 304 on the body.

[0170] In this embodiment, the bristles 304 on the top cover 306 are oriented perpendicular to the bristles 304 on the main body so that the bristles 304 can clean the entire inner wall and bottom wall of the cup body, achieving all-round cleaning of the inner cavity 202 of the cup body and ensuring the cleaning effect.

[0171] In any of the above embodiments, the top cover 306 is an arc top cover 306 , and the bristles on the top cover 306 are perpendicular to the top cover 306 .

[0172] In this embodiment, when using the brush structure 300 to clean the cup body that needs to be cleaned, the brush structure 300 needs to be extended into the cup body that needs to be cleaned. If the top cover 306 has relatively sharp edges, when extending into the cup body that needs to be cleaned, there is a possibility of scratching the inner wall and / or bottom wall of the cup body. In severe cases, the cup body may be broken.

[0173] In order to avoid the above situation, the embodiment of the present application specifically defines the shape of the top cover 306 as an arc, so that when the brush structure 300 is extended into the cup body to be cleaned, it will not scratch the inner wall and / or bottom wall of the cup body due to its sharp edges.

[0174] By limiting the bristles 304 on the top cover 306 to be perpendicular to the top cover 306, the ends of the bristles on the top cover 306 can directly and vertically contact the inner wall of the cup body to be cleaned, so as to obtain the maximum cleaning force on the food residues on the inner wall of the cup body to be cleaned, thereby obtaining the best cleaning effect.

[0175] In any of the above embodiments, the top cover 306 includes a plurality of top plates, and the top cover 306 is obtained by splicing the plurality of top plates.

[0176] In this embodiment, by limiting the shape of the top cover 306, specifically, the top cover 306 is assembled from a plurality of top plates. Therefore, when the main body can be adjusted according to the size of the cup body actually cleaned so that the same brush structure 300 can meet the cleaning requirements of cups of different sizes, the top cover 306 can also change its shape to adapt to the cleaning requirements of cups of different sizes, thereby ensuring the cleaning effect.

[0177] In any of the above embodiments, any top plate and the corresponding bearing portion 302 are an integrated structure.

[0178] In this embodiment, by limiting the top plate and the bearing portion 302 to be an integrated structure, the top cover 306 can be adjusted synchronously while the main body is adjusted according to the size of the cup body actually being cleaned. There is no need to independently set a connecting structure 400 for the top plate, thereby reducing the difficulty of assembling the brush structure 300.

[0179] In addition, since the top plate and the bearing part 302 are an integrated structure, when manufacturing the accessory, the top plate and the bearing part 302 can be manufactured simultaneously, so as to simplify the manufacturing process and reduce the difficulty of manufacturing the brush structure 300.
