Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a cleaning equipment, a floor brush assembly and a roller brush installation assembly. Background Art

[0002] With the development of the field of cleaning equipment, more and more families have begun to use cleaning equipment for household cleaning. Among them, the most prominent is the floor scrubber which is more popular in the current market. Floor scrubbers often have better cleaning power when meeting family needs. They mainly rely on the rotating cleaning of the bottom roller brush and the high suction force that cooperates with it.

[0003] As floor scrubbers have entered daily life in large numbers, users have discovered that after long-term use, their roller brushes will wear out, resulting in reduced cleaning power, and the roller brushes need to be replaced regularly. Currently, the replacement of the roller brush often requires the replacement of the additional mounting accessories connected to the floor brush.

[0004] Based on this, from the user's perspective, the cost of replacement will inevitably increase, and from the manufacturer's perspective, the manufacturing cost of the above-mentioned wearing parts is also relatively high. When their sales prices remain basically unchanged, their relative profits will also suffer certain losses. Utility Model Content

[0005] In order to solve the above-mentioned problem that the installation accessories need to be replaced when replacing the roller brush, the utility model provides a solution that is easy to disassemble and install the roller brush. This solution can replace only the roller brush without replacing the installation accessories connected to the floor brush assembly. The specific solution is as follows.

[0006] The present application provides a cleaning device, including a body and a floor brush assembly connected to the body, the floor brush assembly including: a base; a roller brush assembly, the roller brush assembly including a roller brush body and a support portion arranged on one side of the roller brush body, the support portion being connected to the base via a connecting assembly.

[0007] The connecting assembly comprises a connecting body, one end of which is connected to the base, and the other end of which is connected to the supporting part through a mounting assembly, and the supporting part is rotatably arranged relative to the mounting assembly.

[0008] The mounting assembly includes a control rod, and the support portion is configured such that when the control rod moves along an axial direction thereof, the support portion and the mounting assembly can be separated.

[0009] During daily use, replacement of the roller brush assembly requires replacement of all accessories connected thereto, for example, the connecting assembly connected thereto needs to be replaced together. However, the present solution provides an installation assembly so that the roller brush assembly and the connecting assembly can be separated through the installation assembly.

[0010] In other words, the solution of the present application allows the roller brush assembly to be disassembled separately while retaining the mounting assembly and the connecting assembly. When replacing the roller brush assembly, the user only needs to connect the replaced roller brush assembly to the mounting assembly, and there is no need to replace the mounting accessories connected to the floor brush assembly.

[0011] From the perspective of manufacturing, it can greatly reduce costs. For example, when the above-mentioned consumable parts need to be produced 2,000,000 pieces per year, and there are 10,000 users who purchase cleaning equipment, then the above structure can save the cost of 1,900,000 connection components, which is very profitable for manufacturers.

[0012] At the same time, from the perspective of user experience, driving the control lever can achieve the disengagement between the control lever and the support part without the need for a large number of clips, and its automation is more enhanced. It is conceivable that if the roller brush assembly and the connecting assembly are disassembled by the methods in the prior art, most of them are disassembled by clips, screw connections, forced plugging and unplugging, etc., which are relatively inconvenient for disassembly of the roller brush assembly, and require users to spend more time or effort to disassemble, resulting in poor user experience.

[0013] In one achievable manner, the movement of the control rod along its axial direction is configured such that the control rod moves toward the supporting portion.

[0014] The above solution describes that the user can release the connection between the above installation component and the support part by pressing, and the pressing method is more convenient for the user.

[0015] In one achievable manner, the movement of the control rod along its axial direction is configured such that the control rod moves away from the supporting portion.

[0016] It has been described above that the connection between the mounting assembly and the support portion can be released by pressing, and correspondingly, the connection between the mounting assembly and the support portion can be released by pulling. The above two methods are relatively convenient compared to other methods.

[0017] In one achievable manner, the mounting assembly includes a fixing member, the support portion is sleeved on the outside of the control rod, and a fixing member is provided between the support portion and the control rod. When the control rod moves toward the support portion, the fixing member is disengaged from the support portion.

[0018] The above solution introduces a fixing member, and when the user controls by pressing the control lever, the fixing member can be disengaged from the support portion, so that the roller brush assembly can be replaced.

[0019] In one achievable manner, the support portion is connected to the control rod, and when the control rod is displaced toward the support portion, one end of the control rod connected to the support portion shrinks and deforms inwardly, thereby achieving the disengagement of the support portion.

[0020] Another disengagement method is described above, that is, when the user does not need to replace the control rod, the control rod can be pressed against the support part, thereby achieving the connection between the control rod and the support part.

[0021] When the user needs to replace the brush, the user can press the control rod to retract inward, so that a gap appears between the control rod and the support portion, that is, the roller brush assembly can be detached for corresponding replacement.

[0022] In one achievable manner, the control rod is provided with a limiting portion, the limiting portion is in contact with the fixing member, and when the control rod is displaced toward the supporting portion, the limiting portion is displaced and guides the fixing member to be disengaged from the supporting portion.

[0023] In this embodiment, the control rod is provided with a limiting portion. When the user has no intention to replace the control rod, the limiting portion abuts against the fixing member, and the fixing member abuts against the supporting member, thereby realizing the connection between the control rod and the supporting member. When the user needs to replace the control rod, the limiting portion of the control rod is displaced by pressing the control rod, and the fixing member is displaced accordingly. The displacement of the fixing member is affected by the displacement of the limiting portion, and the fixing member moves toward the control rod, thereby generating a distance between the fixing member and the supporting member, that is, the two are disengaged, and the user can perform corresponding replacement at this time.

[0024] In one achievable manner, the limiting portion includes a limiting groove, one end of which is provided with a first slope portion, and when the control rod does not move, the first slope portion contacts and presses against the fixing member to achieve connection between the fixing member and the support portion. When the control rod moves toward the support portion, the first slope portion moves, and the fixing member moves toward the limiting groove to achieve separation from the support portion.

[0025] In this solution, a limiting portion is provided as a limiting groove, and a first slope portion is provided at one end of the limiting groove. When the user has no intention to replace it, that is, when the control rod has not moved, the first slope portion abuts against the fixing member, so that the fixing member is connected to the support.

[0026] When the user needs to replace it, he presses the control rod, and the first slope portion is displaced accordingly, which causes the abutting position to disappear and the fixing part to lose its abutting force, so it will move toward the limiting groove. At this time, the user can make the corresponding replacement.

[0027] At the same time, it should be understood that the above scheme introduces pressing the control rod to move the slope part so that the fixing part moves toward the limit groove, thereby forming a disengagement between the support part and the fixing part. In fact, the above function can also be achieved by pulling out, that is, by pulling out, the control rod is displaced, thereby moving the fixing part, and then achieving the disengagement of the fixing part from the support part.

[0028] In one achievable manner, the first slope portion is configured to be disposed on a side of the limiting groove away from the connecting body.

[0029] In this solution, the first slope portion is arranged on a side of the limiting groove away from the connecting body so that its position can match the pressing method.

[0030] Imagine that when pressed, the control rod moves toward the support part, and the first slope part gradually moves away from the contact position of the fixing part, resulting in the limiting groove gradually contacting the fixing part. In this way, the fixing part will be displaced toward the limiting groove and thus disengaged from the support part, and the roller brush assembly can be replaced.

[0031] Of course, it should be understood that this can also be adapted to the pulling-out method, that is, the first slope portion is set at a position close to the side of the connector in the limiting groove. During the pulling-out process, the first slope portion will also gradually move away from the fixing part, thereby guiding the fixing part to move toward the limiting groove, thereby achieving replacement.

[0032] In one feasible manner, the limiting portion includes a limiting boss, and a second slope portion is provided at one end of the limiting boss. When the control rod does not move, the limiting boss abuts against and presses the fixing member to achieve the connection between the fixing member and the supporting portion. When the control rod moves toward the supporting portion, the fixing member moves to contact the second slope portion to achieve disengagement from the supporting portion.

[0033] This solution provides another type of limiting portion, that is, when the limiting portion is configured as a limiting boss, during normal use, the limiting boss abuts against the fixing member to achieve connection with the supporting portion.

[0034] When the roller brush assembly needs to be replaced, the control rod is moved to disengage the limiting boss from the fixing member, so that the roller brush assembly can be replaced.

[0035] In one achievable manner, the second slope portion is disposed on a side of the limiting boss close to the connecting body.

[0036] Similarly, in this scheme, the second slope portion is arranged on the side of the limiting boss close to the connecting body. Imagine that when the control rod is pressed, that is, the control rod moves close to the supporting portion, the limiting boss mainly disengages from the fixing part, and the second slope portion comes with it, which can guide the fixing part to move toward the low position, thereby disengaging from the supporting part. The high position here refers to the position of the limiting boss, and the low position refers to other positions on the outside of the control rod except the protruding position of the limiting boss.

[0037] In one achievable manner, the mounting assembly includes a fixing member connected to the supporting portion, and when the control rod moves along its axial direction and contracts inwardly, the fixing member is disengaged from the supporting portion.

[0038] The present application also provides a connection solution, which also has a fixing member. The connection method of the fixing member here is to achieve disengagement from the support part by contracting the control rod, and the roller brush assembly can also be replaced by pressing.

[0039] In one achievable manner, the fixing member is configured as a buckle provided on the outside of the control rod, the support portion is provided with a slot engaged with the buckle, and when the control rod contracts, the buckle is disengaged from the slot.

[0040] In this solution, the fixing part is directly configured as a part of the control rod, that is, the buckle in the text, and the supporting part is provided with a corresponding slot. When the control rod shrinks and deforms, the buckle and the slot can be forcibly disengaged, so that the roller brush assembly can be replaced.

[0041] In one achievable manner, the mounting assembly includes a support tube, the control rod is inserted into the support tube, and at least one notch radially penetrating the control rod is provided at one end close to the support portion.

[0042] The control rod is also provided with a first protrusion on the outside, and the support tube is provided with a second protrusion on the inside. When the control rod is configured to move toward the support portion, the first protrusion contacts the second protrusion, thereby forcing the control rod to shrink toward one end of the slot.

[0043] The fixing member passes through the supporting tube and is arranged between the control rod and the supporting portion. When the control rod contracts, the fixing member moves away from the supporting portion, thereby realizing the disengagement of the supporting portion.

[0044] The above scheme provides a scheme for setting up a support tube, in which the control rod is inserted into the support tube, and a through slot is provided at one end of the control rod. The setting of the above slot provides the control rod with deformation space, and a second protrusion and a first protrusion are respectively provided on the inner side of the support tube and the outer side of the control rod, so that the two can contact each other when the control rod moves. It can be imagined that after the two contact each other, the control rod continues to move, and the second protrusion of the support tube will inevitably force the control rod to move toward the slot provided therein, thereby realizing the contraction deformation of the control rod.

[0045] At the same time, the fixing part passes through the support tube to respectively connect the control rod, the support tube and the support part, so that the control rod is connected to the support part through the fixing part. In other words, the control rod has the basis for directly controlling the fixing part and the support part. When the control rod contracts, the fixing part moves to achieve disengagement from the support part.

[0046] Of course, it is conceivable that at least the portion of the control rod in contact with the fixing member may also be made of an elastic material, which can shrink and deform to achieve the disengagement of the fixing member from the support tube.

[0047] In one achievable manner, a bearing is disposed in the connector, and the mounting assembly includes a support tube, one end of the support tube is inserted into the bearing, and the other end of the support tube is inserted into the support portion.

[0048] The control rod is inserted into the support tube and can move relative to the support tube. The fixing member passes through the support tube and is arranged between the control rod and the support part to form a connection between the control rod, the support tube and the support part.

[0049] The above scheme introduces a method in which the support tube can drive the support part to rotate, that is, a method in which the roller brush assembly can be driven to rotate. At the same time, the fixing part and the control rod can be used to realize the disengagement and connection between the fixing part and the support part.

[0050] In one achievable manner, the fixing element is configured as a spherical structure.

[0051] The above solution introduces that the fixing member can be a spherical structure, that is, the fixing member can be a structure similar to a ball, and since it will not be restricted by edges and corners, it will be smoother when moving.

[0052] In one practicable manner, the control rod is provided with a plurality of the fixing members around its circumference, and when the control rod moves toward the supporting portion, the plurality of the fixing members are disengaged from the supporting portion.

[0053] The above also provides a solution of multiple fixing parts. When only one fixing part is arranged around the circumference of the control rod, it may shake. Therefore, multiple fixing parts can be arranged around the circumference to enhance its stability.

[0054] In one feasible manner, a third protrusion is provided on the outer side of the control rod, a fourth protrusion is provided on the inner side of the support tube, and a spring is sleeved on the outer side of the control rod, one end of the spring abuts against the third protrusion, and the other end of the spring abuts against the fourth protrusion, so that the spring can be used to reset the control rod after it moves relative to the support tube.

[0055] The above scheme provides a scheme of adding a spring to the control rod. By setting the third protrusion and the fourth protrusion, when the control rod moves and after the movement is completed, it can be reset accordingly through the spring, making it more convenient to operate.

[0056] In one feasible manner, the support tube is provided with a receiving opening at least equal to the diameter of the fixing member, and a retaining ring is also provided on the outside of the support tube. The retaining ring is embedded between the support tube and the fixing member to prevent the fixing member from slipping out of the support tube.

[0057] The scheme further provides a scheme for connecting the support tube and the fixing part, as well as a structure for limiting the fixing part. It should be understood that the movement of the fixing part is controlled by moving the control rod to achieve the disengagement between the fixing part and the support part, which requires the movement of the fixing part. However, it is possible that when the control rod moves too fast, it may fall out of the outside of the support tube. For this reason, the present application provides a scheme for limiting using a retaining ring, which can prevent the fixing part from falling out toward the outside of the support tube.

[0058] In one achievable manner, the support tube is configured to include a fixed section and a connecting section connected thereto, the fixed section is configured as a cylindrical structure and passes through the bearing and is fixed thereto, the connecting section is configured as a square structure, the support portion is provided with a square slot, the connecting section is detachably inserted into the square slot, and is connected to the support portion via the fixing member.

[0059] The above scheme introduces that the support tube can be divided into two sections, namely a square section connected to the support part and a cylindrical section connected to the bearing. The setting of the square section can prevent the support part from being disengaged during rotation. Imagine that when circles are in contact and fit, if the two are not completely fixed, then as the rotation speed increases, the two are easy to be disengaged. However, this problem can be avoided by using a square structure, and its four sharp corners can be used to limit its rotation.

[0060] In one achievable manner, the support portion is configured with a bayonet for accommodating a portion of the fixing member, so that when the fixing member is connected to the support portion, a portion of the fixing member is clamped in the bayonet, thereby preventing the support portion from being disengaged.

[0061] The above scheme introduces a better connection method between the support part and the fixing part, that is, a bayonet is provided on the inner side of the support part, which can accommodate part of the fixing part. That is to say, when the fixing part is pressed by the control rod, a part of it is sunk into the control rod, and the other part is sunk into the bayonet on the inner side of the support part. In this way, the three can be connected more tightly.

[0062] In one feasible manner, a fixing ring is provided inside the support portion, the control rod is passed through the fixing ring, the fixing ring is configured to be made of metal material, and the fixing ring is configured to have a bayonet for accommodating part of the fixing member, so that when the fixing member is connected to the support portion, part of the fixing member is clamped in the bayonet, thereby preventing the support portion from being detached.

[0063] The above scheme further introduces a better way to connect the support part and the fixing member, that is, by providing a fixing ring. The fixing ring can be provided with a metal material, so that the rigidity of the connection is stronger.

[0064] It should be understood that the support part in this solution is part of the roller brush assembly, which means it is also a wearing part. Therefore, by setting a small part of it to be made of metal material, it can not only increase the strength of the connection, but also avoid the solution where the entire support part is made of metal material in pursuit of rigidity. In other words, the setting of the fixing ring not only ensures the connection strength, but also saves certain costs.

[0065] In one achievable manner, the bayonet is configured as an arc-shaped notch provided on one side or both sides of the fixing ring.

[0066] The bayonet solution has been introduced above. Here, it is further provided that the above-mentioned bayonet can be set as an arc-shaped notch on one side or both sides of the fixing ring. The arc-shaped notch can adapt to the spherical fixing part, and it is set on both sides of the fixing ring. Then, the processing difficulty is significantly reduced compared to setting it on the inner side of the fixing ring.

[0067] In one feasible manner, a limit ring is provided at one end of the control rod extending out of the support tube and close to the support portion. The limit ring is clamped on the control rod and protrudes from the connecting port between the control rod and the support tube, thereby limiting the extension length of the control rod.

[0068] Based on the above technical problems, the utility model also provides a floor brush assembly, and the specific solution is as follows.

[0069] The floor brush assembly includes: a base; a roller brush assembly, the roller brush assembly includes a roller brush body and a support portion arranged on one side of the roller brush body, the support portion is connected to the base through a connecting assembly; the connecting assembly includes a connecting body, one end of the connecting body is connected to the base, and the other end is connected to the support portion through an installation assembly, and the support portion is rotatable relative to the installation assembly; the installation assembly includes a control rod, and the support portion is configured so that when the control rod moves along its axial direction, the support portion and the installation assembly can be separated.

[0070] Correspondingly, a roller brush mounting assembly is also provided, which is used for mounting a roller brush of a cleaning device. A support portion is installed on one side of the roller brush, and the support portion is connected to the mounting assembly. The mounting assembly includes a control rod, and the support portion is configured so that when the control rod moves along its axial direction, the support portion and the mounting assembly can be separated.

[0071] It should be understood that the technical effects described above are not all the technical effects of the present invention, and other effects will be further described below. BRIEF DESCRIPTION OF THE DRAWINGS

[0102] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0103] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0104] Currently, more and more users are starting to use cleaning equipment to clean their homes, especially the currently popular floor scrubbers. For example, a floor scrubber has a body and a floor brush assembly connected to it. When cleaning, users only need to push the handle on the body. Floor scrubbers generally also include a clean water tank and a dirty water tank. During the cleaning process, the liquid distributor in the floor brush assembly will guide water from the clean water tank to spray water on the roller brush body in the floor brush assembly. In this way, the roller brush body will clean the cleaning surface, and the cleaning surface will be wetted by the roller brush body to achieve better stain cleaning.

[0105] During the cleaning process, the roller brush will suck the dirt into the sewage tank through rotation and suction of the body. It can be seen that the roller brush body is actually a very important cleaning component in the floor scrubber. It can clean the cleaning surface through high-speed rotation. It is conceivable that after a long period of cleaning, the roller brush body will be greatly worn, and the worn roller brush body will affect the subsequent cleaning effect.

[0106] For this reason, the roller brush body needs to be replaced in time after being used for a period of time. In fact, the roller brush body has become a consumable. However, the replacement of the roller brush body now is not just replacing the roller brush body itself, but also the connection components connected to the base need to be replaced together.

[0107] In other words, there is no device in the current prior art that can portable install or disassemble the roller brush assembly and the connecting assembly. The roller brush assembly is inseparable from the connecting assembly, so it needs to be replaced together during replacement. It can be imagined that the cost waste incurred in the process is very high, both for users and manufacturers.

[0108] In response to the above problems, the present application provides a solution for portable installation or disassembly of a roller brush assembly and a connecting assembly, and the installed roller brush assembly will not be affected during use. The specific solution is as follows.

[0109] refer to Figures 1 to 4 As shown, Figure 1 A cleaning device is provided, which includes a body 200 and a floor brush assembly 100 connected thereto. The body 200 and the floor brush assembly 100 cooperate with each other to clean a surface to be cleaned.

[0110] Figure 2 A floor brush assembly 100 is shown, which includes a roller brush assembly 1, a connecting assembly 2, and a base 3. The roller brush assembly 1 is connected to the base 3 via the connecting assembly 2. In the current prior art, when replacing the roller brush assembly 1, the roller brush assembly 1 and the connecting assembly 2 need to be replaced together.

[0111] In the present application, the connecting component 2 is connected to the roller brush component 1 via the mounting component 201. The mounting component 201 includes a control rod 2011. When the control rod 2011 is configured to move along its axis, the roller brush component 1 and the connecting component 2 can be separated. In other words, in the present application, the roller brush component 1 can be disassembled via the control rod 2011. Of course, it should be understood that it can also be installed via the mounting component 201 during installation.

[0112] See also Figure 3 As shown, it can be seen that the roller brush assembly 1 is in a state where the roller brush assembly 1 is disengaged from the connecting assembly 2 by means of the installation assembly 201. At this time, when replacing the roller brush assembly 1, only the roller brush assembly 1 needs to be replaced, and the roller brush assembly 1 and the connecting assembly 2 are no longer required to be replaced together.

[0113] See also Figure 4 As shown, it shows the state when the roller brush assembly 1 is connected to the connecting assembly 2. It can be reliably installed through the installation assembly 201, and then connected to the base 3 to perform cleaning actions.

[0114] Specifically, the roller brush assembly 1 includes a roller brush body 102 and a support portion 101 disposed on one side of the roller brush body 102. It should be understood that the support portion 101 can be disposed inside the roller brush body 102 and located on one side of the roller brush body 102, or can be directly connected to the outside of the roller brush body 102. The roller brush body 102 has a roller brush cavity 103 (see Figure 3 shown).

[0115] The connecting component 2 includes a connecting body 202 , one end of which is connected to the base 3 via the mounting component 201 , and the supporting portion 101 is rotatably connected relative to the mounting component 201 , so that the roller brush body 102 is rotatably connected relative to the mounting component 201 by relying on the supporting portion 101 .

[0116] The mounting assembly 201 further includes a control rod 2011. In one embodiment, the connection between the mounting assembly 201 and the support portion 101 can be disengaged by moving the control rod 2011, so that the assembly or disassembly of the roller brush assembly 1 can be controlled by manipulating the control rod 2011. It should be noted that the movement of the control rod 2011 here can be manually operated by the user, and of course it can also be automatically operated by automated equipment, such as cooperating with some driving structures to realize the movement of the control rod 2011, and the driving structure here can be a gear rack, a screw, a cam, a cylinder, etc.

[0117] In one embodiment, the control rod 2011 can be configured to move along the axial direction of the control rod 2011. From the perspective of movement, the control rod 2011 can be moved by pressing or pulling.

[0118] Specifically, the pressing method is to drive the control rod 2011 to move toward the support portion 101 , and the pulling method is to drive the control rod 2011 to move away from the support portion 101 or to drive the control rod 2011 to move closer to the connecting body 202 .

[0119] Please continue to see Figure 5 as well as Figure 6 As shown, Figure 5 An implementation scheme of the installation component 201 is shown. Specifically,

[0120] The mounting assembly 201 includes a control rod 2011, and the support portion 101 is sleeved on the outside of the control rod 2011, with a fixing member 2016 provided therebetween. The fixing member 2016 connects the support portion 101 and the control rod 2011. When the control rod 2011 is driven to move, the fixing member 2016 is disengaged from the support portion 101, thereby separating the support portion 101 from the control rod 2011.

[0121] The disengagement here means that the fixing member 2016 also moves under the movement of the control rod 2011, so that it is no longer in contact with the support part 101, thereby achieving the disengagement between the fixing member 2016 and the support part 101.

[0122] Of course, in another feasible solution, the separation from the support part 101 can be achieved directly through the deformation of the control rod 2011 itself. Specifically, the support part 101 is sleeved on the outside of the control rod 2011. When separation is required, the control rod 2011 is driven to move, so that the control rod 2011 shrinks and deforms, so that the support part 101 can be separated from the control rod 2011.

[0123] During normal use, the control rod 2011 abuts against the support portion 101, that is, the control rod 2011 is directly connected to the support portion 101. When it is necessary to disengage, the control rod 2011 is retracted to form a gap between the support portion 101, so that the roller brush assembly 1 can be disassembled.

[0124] In an practicable solution, a limiting portion 2017 is further provided on the control rod 2011. The limiting portion 2017 abuts against the fixing member 2016 during normal use. When the roller brush assembly 1 needs to be disassembled, the limiting portion 2017 is driven to move by driving the control rod 2011 to move, so that the fixing member 2016 loses the abutting force and is disengaged from the support portion 101. It should be understood that the movement of the control rod 2011 here includes both movement toward the support portion 101 and movement away from the support portion 101.

[0125] The limiting portion 2017 is used to limit the position of the fixing member 2016 so that the fixing member 2016 can be fixed and released more reliably, thereby providing a better user experience.

[0126] Please continue to refer to Figure 5 , Figure 6 , Figure 8 As shown, in an implementable solution, the limiting portion 2017 includes a limiting groove 20172, and a first slope portion 20171 is provided on one side of the limiting groove 20172. In normal use, the first slope portion 20171 abuts against the fixing member 2016, so that the support portion 101 is connected to the control rod 2011. When the control rod 2011 moves, the first slope portion 20171 moves and disengages from the fixing member 2016, so that the roller brush assembly 1 can be replaced.

[0127] In one feasible solution, Figure 5As shown, the first slope portion 20171 is arranged on the side of the limiting groove 20172 away from the connecting body 202. On this basis, by driving the control rod 2011 to move toward the supporting portion 101, the first slope portion 20171 and the fixing member 2016 can be disengaged, so that the roller brush assembly 1 can be replaced.

[0128] In another feasible scheme, the first slope portion 20171 can of course also be arranged on the side of the limiting groove 20172 close to the connecting body 202. By driving the control rod 2011 to move away from the supporting portion 101, the first slope portion 20171 and the fixing member 2016 can be disengaged, and the roller brush assembly 1 can be replaced in the same way.

[0129] In an implementable solution, the limiting portion 2017 is configured as a boss structure, and the specific solution is as follows.

[0130] refer to Figure 7 , Fig. 9 As shown, the limiting portion 2017 provided on the control rod 2011 includes a limiting boss 20173 and a second slope portion 20174 provided on one side of the limiting boss 20173. Similarly, in normal use, the limiting boss 20173 abuts against the fixing member 2016, thereby providing abutting force to the fixing member 2016 to ensure its connection with the support portion 101, and after the control rod 2011 is driven to move by an external force, the limiting boss 20173 gradually disengages from the fixing member 2016. The fixing member 2016 gradually loses connection with the support portion 101 along the second slope portion 20174, so that the fixing member 2016 is disengaged from the support portion 101.

[0131] It should be understood that two driving modes of the control rod 2011 are also covered here, and the specific scheme is as follows.

[0132] Please continue to refer to Figure 7 as well as Fig. 9 As shown, the second slope portion 20174 is arranged on the side of the limiting boss 20173 close to the connecting body 202. On this basis, when the driving control rod 2011 moves toward the support portion 101, the limiting boss 20173 will gradually disengage from the fixing member 2016, and the fixing member 2016 will disengage from the fixing member 2016 along the second slope portion 20174.

[0133] In an implementable solution, the second slope portion 20174 is arranged on the side of the limiting boss 20173 away from the connecting body 202. On this basis, when the driving control rod 2011 moves away from the supporting portion 101, the limiting boss 20173 and the fixing member 2016 are disengaged, and at the same time, the fixing member 2016 will also be disengaged from the fixing member 2016 along the second slope portion 20174.

[0134] It should be specially noted that the slope portion here is not limited to being composed of an inclined surface, and it can certainly also be composed of a curved surface or a surface of other shapes.

[0135] In an practicable solution, the installation or release can also be achieved by deforming the control rod 2011 itself and cooperating with the fixing member 2016, as described below.

[0136] refer to Fig.10 As shown, the above has introduced a solution that the control rod 2011 can be directly disengaged from the support part 101 by deforming itself, and what is introduced here is a solution that utilizes the deformation of the control rod 2011 itself and cooperates with the fixing member 2016 to disengage the support part 101. The specific solution is as follows.

[0137] A fixing member 2016 is provided between the control rod 2011 and the support portion 101. When the control rod 2011 contracts inwardly under the action of an external force, the fixing member 2016 loses the abutting force of the control rod 2011, so that the fixing member 2016 and the support portion 101 are gradually separated.

[0138] In an implementable solution, the fixing member 2016 is configured as a buckle in the control rod 2011 (not shown in the figure), and a slot (not shown in the figure) matching with the buckle in the control rod 2011 is provided in the support portion 101 .

[0139] In normal use, the buckle in the control rod 2011 engages with the slot of the support part 101 to achieve the connection between the two. When replacement is required, the control rod 2011 is driven to move, so that the buckle and the slot are disengaged to achieve the purpose of replacing the roller brush assembly 1.

[0140] Please continue to refer to Fig.10 As shown, in another feasible solution, the mounting assembly 201 includes a support tube 2014, a control rod 2011 is inserted into the support tube 2014, and a fixing member 2016 passes through the support tube 2014 and is respectively connected to the control rod 2011 and the support portion 101.

[0141] A first protrusion 20112 is disposed on the outer side of the control rod 2011, a second protrusion 20144 is disposed on the inner side of the support tube 2014, and at least one end of the control rod 2011 is disposed with a notch that radially penetrates the control rod 2011. When the control rod 2011 moves, the first protrusion 20112 contacts the second protrusion 20144, because the control rod 2011 is provided with a notch that penetrates the control rod 2011. Therefore, the second protrusion 20144 forces the control rod 2011 to shrink toward the notch, thereby achieving the purpose of shrinking the control rod 2011, thereby realizing the disengagement of the fixing member 2016 from the support portion 101.

[0142] Of course, the above-mentioned contraction method is only one solution provided in this case, and other solutions may also be adopted. For example, the control rod 2011 is at least partially set to an elastically contractible structure. For this purpose, when the control rod 2011 moves the elastically contractible structure to the position of the fixing member 2016, the control rod 2011 is contracted to achieve the disengagement of the fixing member 2016 from the support portion 101.

[0143] Please refer to Figures 5 to 7 As shown, the connection component 2 includes a connection body 202, one end of the connection body 202 is connected to the installation component 201, and the other end is connected to the base 3. In this embodiment, the connection body 202 can be a plate structure or a columnar structure, etc.

[0144] A mounting boss 2020 is provided at one end of the connecting body 202, a bearing 2015 is provided in the mounting boss 2020, and the support cylinder 2014 is provided in the bearing 2015, thereby ensuring that the support cylinder 2014 can rotate.

[0145] The control rod 2011 is inserted into the support tube 2014 and connected to the support part 101 through the fixing part 2016, so that the support part 101 can rotate relative to the connecting body 202, that is, the rotation of the roller brush assembly 1 and the effective connection are guaranteed here, and it can also be easily disassembled or assembled.

[0146] Please continue to refer to Figures 5 to 7 As shown, in the various embodiments provided above, the fixing member 2016 is configured as a spherical structure. In other words, the fixing member 2016 is configured as a ball in one or more embodiments. The use of the spherical structure can make it easier for the fixing member 2016 to be detached from the support portion 101. Compared with a structure with sharp corners, the surface of the spherical structure is smoother and less susceptible to jamming.

[0147] Various solutions for disassembly or assembly using the fixing part 2016 have been described above, and most of the above solutions are described with a single fixing part 2016. In the solution of the utility model, a solution for fixing with multiple fixing parts 2016 is also provided. When a single fixing part 2016 is connected, it is only subjected to the connecting force at one angle or plane, and therefore, it may be unstable such as shaking.

[0148] In order to solve the above problem, the control rod 2011 can be provided with a plurality of fixing members 2016 around its axial direction. Of course, its control method is similar to the above scheme, and the disengagement operation is also performed by the control method mentioned above, that is, when the control rod 2011 is driven to move, for example, when the control rod 2011 is driven to move toward the support part 101, the plurality of fixing members 2016 are disengaged from the support part 101.

[0149] At the same time, in order to prevent the control rod 2011 from being disengaged during movement, the utility model also provides a solution for limiting the control rod 2011, as follows.

[0150] refer to Fig.11 As shown, the control rod 2011 is inserted into the support tube 2014 and protrudes from the support tube 2014. A limiting ring 2019 is provided on the side that protrudes from the support tube 2014 and is close to the support portion 101. The limiting ring 2019 protrudes from the connection port between the control rod 2011 and the support tube 2014. In this way, the control rod 2011 can be prevented from being disengaged from the connector 202 or can be limited at a suitable position, thereby limiting the extension distance of the control rod 2011.

[0151] The above describes in detail the scheme of controlling the movement of the control rod 2011 and controlling the disengagement or assembly. On this basis, the present invention also provides a scheme for resetting the control rod 2011. The specific scheme is as follows.

[0152] Please refer to Figure 7 As shown, a fourth protrusion 20143 is provided on the inner side of the support tube 2014, a third protrusion 20111 is provided on the outer side of the control rod 2011, and a spring 2012 is provided on the outer sleeve of the control rod 2011, one end of the spring 2012 abuts against the fourth protrusion 20143, and the other end abuts against the third protrusion 20111.

[0153] In this way, after the control rod 2011 moves, it can be reset by the spring 2012. From the user experience point of view, the reset by the spring 2012 will make the disassembly and assembly more convenient.

[0154] In another embodiment, since the fixing member 2016 passes through the support tube 2014 and when the fixing member 2016 is based on a spherical structure, if the roller brush assembly 1 is replaced, then after the roller brush assembly 1 is removed, the fixing member 2016 loses support at one end and is likely to fall out of the support tube 2014. In order to solve the above problem, the utility model also provides a solution that can effectively prevent the fixing member 2016 from falling out in the above scenario.

[0155] Please refer to Figure 12-14 As shown, a receiving opening 2013 is provided on the outside of the support tube 2014, and the diameter of the receiving opening 2013 is at least equal to the diameter of the fixing member 2016, so that the fixing member 2016 can pass through the support tube 2014. In order to prevent the fixing member 2016 from falling out, a retaining ring 2018 is added on this basis. The retaining ring 2018 includes an outer ring and an inner ring. The outer ring is adapted to the opening size of the receiving opening 2013, and the inner ring is adapted to the spherical surface of the fixing member 2016.

[0156] When installing the support tube 2014 and the fixing member 2016 , the fixing member 2016 can be first placed in the receiving port 2013 and then the clamping ring 2018 can be clamped outside the fixing member 2016 and connected to the receiving port 2013 .

[0157] It should be understood that the connection method here is not limited, and it can be connected by gluing or snapping. In this way, the setting of the snap ring 218 can further ensure the stability of the fixing part 26 when the roller brush assembly 1 is installed or disassembled.

[0158] The connection relationship between the support part 101 and the support cylinder 2014 has been described above, and the support part 101 can be supported and rotated by the support cylinder 2014. It should be understood that the roller brush of the cleaning device rotates at a relatively fast speed during the cleaning process. Therefore, there may be a risk of disengagement or slipping between the support cylinder 2014 and the support part 101. Based on this, the utility model also provides a solution to the above problem, which is as follows.

[0159] Please refer to Fig.11 as well as Fig.17 As shown, the support cylinder 2014 includes a fixed section 20141 and a connecting section 20142, and the fixed section 20141 is a cylindrical structure and is sleeved on the inner ring of the bearing 2015. The connecting section 20142 is set as a square structure, and a square notch matching with it is set inside the support part 101, and the connecting section 20142 is inserted into the square notch. Therefore, the rotation transmission between the support part 101 and the support cylinder 2014 includes two ways. The first is that the fixing member 2016 connects the support cylinder 2014 and the support part 101, so when the support cylinder 2014 rotates, it will naturally drive the support part 101 to rotate; the second is the square structure of the two. Because it is a square structure, when the support cylinder 2014 rotates, it can drive the support part 101 to rotate through the above four corners.

[0160] That is to say, the above rotation is carried out by coordinating the two modes, thereby making the transmission more stable.

[0161] The above describes that the square structure is used for matching, so that it can be more stable when rotating, but at the same time the above solution will also bring a defect. The matching of the square structure will increase the wear, especially the above-mentioned sharp-angle structure. In order to solve the above problem, the utility model also provides a solution that can slow down the wear, as follows.

[0162] like Fig.11 , 15As shown in FIGS. 16 , a fixing ring 1012 is disposed in the support portion 101 . The fixing ring 1012 is configured to be made of metal material. The control rod 2011 is disposed in the fixing ring 1012 , that is, the connecting section 20142 is inserted into the fixing ring 1012 .

[0163] In one embodiment, the fixing ring 1012 is connected to the connecting section 20142 using a square structure. Since the fixing ring 1012 is made of metal material, its hardness is relatively higher, and its wear can be alleviated to a certain extent during high-speed rotation. In other words, the use of the fixing ring 1012 not only ensures the stability of the transmission but also solves the problem of its easy wear.

[0164] The above has described in detail the solution for connecting the control rod 2011 to the support portion 101 via the fixing member 2016. On this basis, the present invention further provides a solution for improving the stability of the fixing member 2016 and the support portion 101 after assembly, as follows.

[0165] The inner side of the support portion 101 is provided with a slot 1011 for accommodating part of the fixing member 2016 . When the fixing member 2016 is connected to the support portion 101 , part of it can be locked in the slot 1011 , thereby enhancing the connection stability between the fixing member 2016 and the support portion 101 .

[0166] Furthermore, the above-mentioned bayonet 1011 can be set on one side or both sides of the support part 101, so that it is easier to open the bayonet 1011.

[0167] Of course, in another embodiment, the bayonet 1011 can also be set on the fixing ring 1012, see Fig.15 as well as Fig.16 As shown, the bayonet 1011 is an arc-shaped notch 10122 arranged on one side or both sides of the fixing ring 1012. The fixing ring 1012 includes a main body 10121. A snap-fitting cavity 10123 is arranged in the main body 10121. The support tube 2014 is snap-fitted in the snap-fitting cavity 10123. The arc-shaped notch 10122 is arranged on one side or both sides of the snap-fitting cavity 10123.

[0168] When the fixing member 2016 contacts the fixing ring 1012 , it is locked in the arc-shaped notch 10122 , thereby achieving a more stable connection.

[0169] The above describes a cleaning device that can realize convenient disassembly and installation of the roller brush assembly 1. On this basis, the utility model also provides a floor brush assembly, which can also solve the above technical problems. The specific solution is as follows.

[0170] A floor brush assembly comprises: a base 3 and a roller brush assembly 1, the roller brush assembly 1 comprises a roller brush body 102 and a support portion 101 arranged on one side of the roller brush body 102, the support portion 101 is connected to the base 3 via a connecting assembly 2; the connecting assembly 2 comprises a connecting body 202, one end of the connecting body 202 is connected to the base 3, and the other end is connected to the support portion 101 via an installation assembly 201, and the support portion 101 is rotatable relative to the installation assembly 201; the installation assembly 201 comprises a control rod 2011, and the support portion 101 is configured so that when the control rod 2011 moves along its axial direction, the support portion 101 and the installation assembly 201 can be separated.

[0171] It should be understood that this solution can also be combined with other further solutions regarding the support portion 101 and the control rod 2011 described above, which will not be repeated here.

[0172] At the same time, the utility model also provides a roller brush mounting assembly, which is used for mounting a roller brush of a cleaning device. A support portion 101 is installed on one side of a roller brush body 102. The support portion 101 is connected to a mounting assembly 201. The mounting assembly 201 includes a control rod 2011. The support portion 101 is configured so that when the control rod 2011 moves along its axial direction, the support portion 101 and the mounting assembly 201 can be separated.

[0173] It should be understood that this solution can also be combined with other further solutions regarding the support portion 101 and the control rod 2011 described above, and no further repetition will be made here.

[0174] Application scenario: When the cleaning device has been used for a long time, its roller brush assembly needs to be replaced. At this time, the roller brush assembly 1 can be pulled out first. Since the connecting assembly 2 is connected to the roller brush assembly 1, it is pulled out in one piece. At this time, by pressing the control rod 2011, the fixing piece 2016 inside the installation assembly 201 is disengaged from the supporting part 101 on one side of the roller brush body 102, so that the roller brush assembly 1 can be pulled out. At the same time, during installation, the control rod 2011 can be pressed to connect the supporting part 101 connected to the roller brush body 102 with the installation assembly 201, so that the roller brush assembly 1 can be assembled. Of course, during installation, the control rod 2011 can also be not pressed, and the pressure of the supporting part 101 on the fixing piece 2016 can be used to connect the roller brush assembly 1 to the connecting assembly 2.

[0175] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for the structural parts or the entire structural technical features therein. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
