[0089] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0090] Currently, cleaning devices require separate installation structures for the rollers and sludge collection tanks, resulting in a highly complex overall installation structure that increases manufacturing costs. Furthermore, the use of multiple fixing points for both rollers and sludge collection tanks increases the failure rate, hindering long-term use and maintenance and reducing cleaning effectiveness. Moreover, the sludge collection tank is prone to shaking or shifting after installation, reducing the overall structural stability and making it difficult for users to determine if it is properly installed, thus affecting the use of the cleaning equipment.

[0091] The following is combined Figures 1-16This describes embodiments of the installation structure, roller assembly, and cleaning equipment of this utility model.

[0092] According to an embodiment of the present invention, in a first aspect, an installation structure is provided for installing a roller assembly of a cleaning device. The roller assembly includes a bracket 1 and a dirt-collecting tank 3, the dirt-collecting tank 3 being detachably mounted on the bracket 1. The installation structure includes a cover 4 and a positioning detection mechanism. The cover 4 is disposed at one end of the dirt-collecting tank 3, the cover 4 is closed and connected to the dirt-collecting tank 3, and the cover 4 is detachably connected to the bracket 1. The positioning detection mechanism is disposed between the bracket 1 and the dirt-collecting tank 3, and is used to detect whether the dirt-collecting tank 3 is properly installed relative to the bracket 1.

[0093] In this installation structure, the cover 4 allows for the installation and removal of one end of the sludge collection tank 3 from the bracket 1, simplifying the installation structure of the sludge collection tank 3. The installation process is simple and quick, significantly improving the replacement efficiency of the sludge collection tank 3 and reducing manufacturing costs. The sludge collection tank 3 will not shake or shift after installation. Furthermore, due to the simple overall structure, it is not easily damaged, has good structural stability, and high reliability, which helps reduce the failure rate of the roller assembly, ensures its service life, and improves the user experience. Moreover, by setting up a positioning detection mechanism, it can accurately detect whether the sludge collection tank 3 is installed correctly, allowing users to understand the installation status of the sludge collection tank 3 in a timely manner, improving the intelligence and reliability of the equipment, without affecting the normal operation of the cleaning equipment, and enhancing the user experience.

[0094] This mounting structure is applied to various cleaning equipment, such as dual-roller sweepers, dual-roller handheld floor scrubbers, and floor cleaning robots. The cleaning equipment includes a roller assembly, which comprises a bracket 1, a roller 2, and a dirt collection tank 3. The roller 2 and dirt collection tank 3 are detachably mounted on the bracket 1 using the mounting structure of this embodiment.

[0095] Specifically, the bracket 1 is the shell structure of the roller assembly. The bracket 1 has a certain structural strength and can support and set up structures such as the roller 2 and the dirt collection tank 3. The roller 2 is set inside the bracket 1, and the roller 2 is the roller mop. There are at least two rollers 2, such as two, three, or four. In this embodiment, there are two rollers 2, and the roller assembly is a double roller assembly. The roller 2 is set on the side of the bracket 1 facing the surface to be cleaned. When the cleaning equipment is working, the roller 2 can rotate and roll to clean the surface to be cleaned. The installation structure of this embodiment can be applied to cleaning equipment such as sweeping machines, mopping machines, floor scrubbers, or cleaning robots. Depending on the application scenario of different cleaning equipment, the surface to be cleaned can be the ground, wall, etc. In this embodiment, the surface to be cleaned is the ground as an example.

[0096] The installation structure includes a cover 4, which is located at one end of the sludge collection tank 3. The cover 4 can cover and connect one end of the sludge collection tank 3, and the cover 4 and the bracket 1 can be detachably connected, thereby realizing the detachable connection between this end of the sludge collection tank 3 and the bracket 1. After the cover 4 and the bracket 1 are installed, the cover 4 is located on one side of the bracket 1.

[0097] When the cover 4 is closed and connected to the sludge collection tank 3, the closing direction is as follows: Figure 2 The direction indicated by the middle arrow a. By setting the cover 4, not only is the installation structure of the dirt collection tank 3 end simplified, enabling quick installation with the bracket 1 and simplifying the installation operation, but the cover 4 also makes the overall appearance of the machine more beautiful and neat, and can prevent dust, debris and other things from entering the inside of the roller 2, affecting the operation and service life of the roller 2.

[0098] A positioning detection mechanism is installed between the support 1 and the dirt collection tank 3 to detect whether the dirt collection tank 3 is properly installed relative to the support 1. For example, when the positioning detection mechanism detects that the dirt collection tank 3 is not installed or is not properly installed, it will issue an alarm to prompt the user to check the installation status of the dirt collection tank 3. In this way, the user can promptly understand the installation status of the dirt collection tank 3, improving the intelligence and reliability of the cleaning equipment and preventing situations where the dirt collection tank 3 is not properly installed, which could affect the cleaning operation of the cleaning equipment.

[0099] Furthermore, it also includes a sludge collection tank limiting structure, which is set between the cover 4 and the sludge collection tank 3 to limit one end of the sludge collection tank 3 to the cover 4.

[0100] One end of the sludge collection tank 3 is connected to the cover 4 through the sludge collection tank limiting structure, thereby realizing a detachable connection with the bracket 1, preventing the sludge collection tank 3 from shaking and shifting position after installation, improving structural reliability, simplifying the installation structure of the sludge collection tank, and improving installation efficiency.

[0101] Furthermore, the sludge collection tank limiting structure includes a first limiting structure and a second limiting structure. The first limiting structure limits the sludge collection tank 3 in a first direction, and the second limiting structure limits the sludge collection tank 3 in a second direction. The first direction and the second direction are set at an angle.

[0102] To achieve reliable limiting installation at one end of the sludge collection tank 3, the sludge collection tank limiting structure includes a first limiting structure and a second limiting structure. The first limiting structure and the second limiting structure cooperate with each other. The first limiting structure limits the sludge collection tank 3 in a first direction, and the second limiting structure limits the sludge collection tank 3 in a second direction. The first direction and the second direction are set at an angle. For example, the included angle between the first direction and the second direction can be an acute angle, a right angle, or an obtuse angle. This can improve the reliability of the limiting installation of the sludge collection tank 3, simplify the installation structure, and improve the installation efficiency.

[0103] Furthermore, the first limiting structure includes a first limiting member 5 and a first limiting groove 6 that cooperate with each other. One of the first limiting member 5 and the first limiting groove 6 is disposed on the cover 4, and the other is disposed on the sludge collection tank 3. The first limiting groove 6 limits the first limiting member 5 in a first direction.

[0104] like Figures 3-6 As shown, the first limiting structure includes a first limiting member 5 and a first limiting groove 6. The first limiting member 5 can be inserted into the first limiting groove 6. One of the first limiting member 5 and the first limiting groove 6 is disposed on the cover 4, and the other is disposed on the sludge collection tank 3. The first limiting groove 6 limits the first limiting member 5 in a first direction.

[0105] In this embodiment, the first limiting member 5 is disposed on the cover 4, and the first limiting member 5 is disposed on the side of the cover 4 facing the sludge collection tank 3. The first limiting member 5 protrudes from the side of the cover 4 facing the sludge collection tank 3 and is disposed along the closing direction. Optionally, the first limiting member 5 is disposed near the middle of the cover 4. Correspondingly, the first limiting groove 6 is disposed on the sludge collection tank 3, and the position and shape of the first limiting groove 6 match the first limiting member 5.

[0106] Specifically, the upper ends of the first limiting member 5 and the first limiting groove 6 are open, and the opposite side of the first limiting member 5 and the first limiting groove 6 is an open structure to facilitate the insertion of the first limiting member 5 and the first limiting groove 6. When the first limiting member 5 and the first limiting groove 6 are inserted and engaged, the first limiting member 5 is embedded in the first limiting groove 6, and the first limiting groove 6 upper limits the first limiting member 5 in a first direction, such as... Figure 6 As indicated by the middle arrow b-b', when the roller assembly is placed on the ground, the first direction is horizontal. Relative to the sludge collection tank 3, the first direction is the left-right direction of the horizontal direction, which is perpendicular to the length direction of the sludge collection tank 3.

[0107] like Figure 6 As shown, the first limiting member 5 includes a bottom portion 501 and two side portions 502. The bottom portion 501 and the two side portions 502 together form the first limiting member 5, and the side portions 502 protrude from the bottom portion 501. The outer walls of the two side portions 502 can abut against the inner wall of the first limiting groove 6, thereby limiting the first limiting member 5 in the first direction, preventing the sludge collection tank 3 from moving relative to the cover 4 in the first direction, and enabling the installation of this end of the sludge collection tank 3 with the cover 4.

[0108] In other embodiments, the first limiting member 5 can also be disposed on the sludge collection tank 3, and the corresponding first limiting groove 6 is disposed on the cover 4. As long as the first limiting groove 6 and the first limiting member 5 can be inserted and cooperated, the cover 4 can limit the sludge collection tank 3 in the first direction.

[0109] Furthermore, the second limiting structure includes a second limiting member 7 and a locking member 8, one of which is disposed on the cover 4 and the other is disposed on the sludge collection tank 3, and the second limiting member 7 limits the locking member 8 in the second direction.

[0110] like Figures 3-6 As shown, the second limiting structure includes a second limiting member 7 and a locking member 8. The second limiting member 7 can abut against the locking member 8, and the second limiting member 7 limits the locking member 8 in the second direction.

[0111] In this embodiment, the second limiting member 7 is disposed on the cover 4, and the second limiting member 7 is disposed on the side of the cover 4 facing the sludge collection tank 3. The second limiting member 7 protrudes from the side of the cover 4 facing the sludge collection tank 3 and is disposed along the closing direction. Correspondingly, the locking member 8 is disposed on the sludge collection tank 3, and the position and shape of the locking member 8 match those of the second limiting member 7.

[0112] In this embodiment, the first direction is perpendicular to the second direction, and the first direction is a horizontal direction, such as... Figure 6 The direction indicated by the middle arrow b-b' is the first direction, and the second direction is the vertical direction, as shown in the image. Figure 6 The direction is indicated by the middle arrow c-c'.

[0113] In other embodiments, the second limiting member 7 may also be provided on the sludge collection tank 3, and the locking member 8 may be provided on the cover 4, as long as the second limiting member 7 and the locking member 8 can cooperate.

[0114] Furthermore, the second limiting member 7 limits the locking member 8 in the first branch direction of the second direction. The second limiting structure also includes a cooperating first limiting member 5 and a first limiting groove 6. One of the first limiting member 5 and the first limiting groove 6 is disposed on the cover 4, and the other is disposed on the sludge collection tank 3. The first limiting groove 6 limits the first limiting member 5 in the second branch direction of the second direction. The first branch direction and the second branch direction are opposite in direction.

[0115] like Figure 6 As shown, in this embodiment, the second direction includes two directions, namely the first branch direction and the second branch direction. The first branch direction is opposite to the second branch direction. Figure 6 The direction indicated by the middle arrow c, the second branch is Figure 6 The direction indicated by the middle arrow c'. When the roller assembly is placed on the ground, the second direction is the vertical direction, the first branch direction is the vertically downward direction, and the second branch direction is the vertically upward direction.

[0116] In this embodiment, the second limiting member 7 limits the locking member 8 in the first branch direction of the second direction. Specifically, the upper surface of the second limiting member 7 abuts against the lower surface of the locking member 8, so that the sludge collection tank 3 cannot move relative to the cover 4 in the first branch direction of the second direction, so as to realize the limiting installation of the cover 4 on the sludge collection tank 3 in the first branch direction of the second direction.

[0117] In this embodiment, the second limiting structure also includes a cooperating first limiting member 5 and a first limiting groove 6. That is, the first limiting member 5 and the first limiting groove 6 can not only limit the sludge collection tank 3 and the cover 1 in the first direction, but also participate in limiting the sludge collection tank 3 in the second direction as part of the second limiting structure. This realizes the full utilization of the structural component's function, improves the utilization rate of the structural component, and makes the installation structure more compact.

[0118] Specifically, the second limiting member 7 and the first limiting member 5 are spaced apart along the second direction, and the first limiting member 5 is positioned above the second limiting member 7. An insertion space is formed between the second limiting member 7 and the first limiting member 5, and the locking member 8 is adapted to be inserted into this insertion space, thereby engaging with the second limiting member 7. Simultaneously, after the first limiting member 5 is inserted into the first limiting groove 6, the bottom 501 of the first limiting member 5 abuts against the bottom of the first limiting groove 6, causing the first limiting groove 6 to limit the first limiting member 5 in the second branch direction of the second direction, preventing the sludge collection tank 3 from moving relative to the cover 4 in the second branch direction of the second direction, thus achieving the limiting installation of the sludge collection tank 3 by the cover 4 in the second branch direction of the second direction.

[0119] In other embodiments, the second limiting member 7 can also be provided on the sludge collection tank 3, and the corresponding locking member 8 can be provided on the cover 4. As long as the second limiting member 7 and the locking member 8 can cooperate, the cover 4 can limit the sludge collection tank 3 in the first direction.

[0120] In other embodiments, the locking member 8 can also be limited in the first and second branches of the second direction by the second limiting member 7. In this case, the limiting installation of the cover 4 on the sludge collection tank 3 in the second direction can be achieved without the aid of the first limiting member 5 and the first limiting groove 6. In this case, the second limiting member 7 can be a limiting slot structure. The limiting slot has an open end only on the side facing the sludge collection tank 3. The locking member 8 can be inserted into the limiting slot through this open end. The top wall of the limiting slot limits the locking member 8 in the second branch direction, and the bottom wall of the limiting slot limits the locking member 8 in the first branch direction. This also achieves the limiting installation of the cover 4 on the sludge collection tank 3 in the second direction.

[0121] Furthermore, the second limiting member 7 is disposed on the side of the cover 4 facing the end of the sludge collection tank 3, and one end of the locking member 8 is disposed in the sludge collection tank 3 through the elastic member 9, and the other end is limited by the second limiting member 7 in the first direction.

[0122] like Figure 8 As shown, the locking member 8 can move relative to the sludge collection tank 3 along the length direction of the sludge collection tank 3 to realize the installation of the sludge collection tank 3 and the cover 4. The locking member 8 is provided at one end of the sludge collection tank 3 near the cover 4, and one end of the locking member 8 is provided to the sludge collection tank 3 by the elastic member 9, and the other end is limited by the second limiting member 7 in the first direction.

[0123] Specifically, the elastic element 9 is a spring, and the elastic deformation direction of the spring is along the length of the dirt-collecting tank 3. One end of the elastic element 9 is connected to the end of the locking element 8 away from the cover 4, and the other end abuts against the dirt-collecting tank 3. When the locking element 8 moves toward the dirt-collecting tank 3, the elastic element 9 is compressed, the dirt-collecting tank 3 enters the installation position, the elastic element 9 is released and reset, and the end of the locking element 8 away from the elastic element 9 is inserted into the insertion space between the first limiting element 5 and the second limiting element 7. The upper surface of the second limiting element 7 abuts against the lower surface of the locking element 8, and the locking element 8 is limited by the second limiting element 7 in the first direction, thereby realizing the limiting installation of the cover 4 on the dirt-collecting tank 3 in the first direction.

[0124] Furthermore, the installation structure also includes a sludge collection tank connection structure, which is located between the end of the sludge collection tank 3 away from the cover 4 and the bracket 1, and is used to connect the end of the sludge collection tank 3 away from the cover 4 to the bracket 1.

[0125] The sludge collection tank 3 has a roughly rectangular parallelepiped shape, with its length parallel to the axis of the roller 2. One end of the sludge collection tank 3 is connected to the cover 4, and the other end is connected to the bracket 1. The end of the sludge collection tank 3 furthest from the cover 4 is connected to the bracket 1 via a sludge collection tank connecting structure, so that both ends of the sludge collection tank 3 can be reliably installed, ensuring that the installed sludge collection tank 3 is stable and highly reliable.

[0126] Furthermore, the sludge collection tank connection structure includes a plug-in 21 and a socket 22 that fit together, one of which is disposed in the sludge collection tank 3 and the other is disposed in the bracket 1.

[0127] The sludge collection tank connection structure includes a plug 21 and a socket 22, which can be plugged into each other, such as... Figures 9-10 As shown. In this embodiment, the plug-in 21 is disposed on the bracket 1, protruding from the bracket 1 and protruding in the direction of the dirt collection tank 3. The insertion hole 22 is disposed at the end of the dirt collection tank 3 facing the bracket 1, and the shape and size of the insertion hole 22 match the bracket 1. During installation, the plug-in 21 is aligned and inserted into the insertion hole 22 to connect the dirt collection tank 3 to the bracket 1.

[0128] In other embodiments, the plug-in 21 can also be disposed on the sludge collection tank 3, and the socket 22 can be disposed on the bracket 1, as long as the plug-in 21 and the socket 22 can be plugged in and cooperate.

[0129] Furthermore, the in-place testing mechanism includes a testing element 35 and a trigger element 36 that cooperate with each other, one of which is located in the sludge collection tank 3 and the other is located in the support 1.

[0130] like Figure 1 , Figure 2 and Figure 11 As shown, the positioning detection mechanism includes a detection element 35 and a trigger element 36. The detection element 35 and the trigger element 36 cooperate with each other. The trigger element 36 can trigger the detection element 35, enabling the detection element 35 to detect the trigger element 36. One of the detection element 35 and the trigger element 36 is disposed on the sludge collection tank 3, and the other is disposed on the support 1. The detection element 35 can be disposed on the sludge collection tank 3 or on the support 1. Correspondingly, the trigger element 36 can be disposed on the support 1 or on the sludge collection tank 3, as long as the two can be matched for detection.

[0131] In this embodiment, the detection element 35 is disposed on the bracket 1, the trigger element 36 is disposed on the dirt collection tank 3, and the trigger element 36 is disposed at the end of the dirt collection tank 3 away from the cover body 4. At this end of the dirt collection tank 3, the dirt collection tank 3 is connected to the bracket 1 through the dirt collection tank connecting structure.

[0132] In this embodiment, the detection element 35 is a Hall sensor, specifically a Hall plate, and the trigger element 36 is a magnet. The detection principle of the Hall sensor and the magnet is based on the Hall effect, the core of which is to convert changes in the magnetic field into a measurable electrical signal. Since this detection principle is existing technology, it will not be described in detail here.

[0133] from Figure 11 It can be seen that the detection component 35 is set near the position where the bracket 1 and the dirt collection tank 3 are installed together, and the trigger component 36 is also set near the end of the dirt collection tank 3 to ensure detection accuracy.

[0134] In other embodiments, the detection element 35 can also be set in the sludge collection tank 3, and the trigger element 36 can be set in the bracket 1. As long as the detection element 35 and the trigger element 36 can cooperate, the positioning detection of the sludge collection tank 3 can be realized.

[0135] Furthermore, the end of the sludge collection tank 3 away from the cover 4 is provided with an installation cavity 301, and the detection element 35 or the trigger element 36 is sealed in the installation cavity 301.

[0136] To ensure the reliability and accuracy of the detection mechanism, an installation cavity 301 is provided at the end of the sludge collection tank 3 away from the cover 4. The installation cavity 301 is recessed inward from the end face of the sludge collection tank 3. The detection element 35 or the trigger element 36 is disposed in the installation cavity 301 to protect the detection element 35 or the trigger element 36.

[0137] Furthermore, in order to further protect the detection element 35 or the trigger element 36, after the detection element 35 or the trigger element 36 is installed in the mounting cavity 301, the mounting cavity 301 is sealed to prevent external dust, water, etc. from entering the mounting cavity 301 and causing damage to the detection element 35 or the trigger element 36, thereby ensuring the reliability and detection accuracy of the positioning detection mechanism and ensuring the service life of the positioning detection mechanism.

[0138] In this embodiment, the trigger 36 is disposed within the mounting cavity 301, with the end of the mounting cavity 301 facing the bracket 1 being an open end. After the trigger 36 is disposed in the mounting cavity 301, the open end of the mounting cavity 301 is sealed by the sealing plug 37, thereby sealing the mounting cavity 301. This sealing structure for the mounting cavity 301 is relatively simple. When it is necessary to install or replace the trigger 36, it is only necessary to pull out the sealing plug, which is easy to operate and has a good sealing effect.

[0139] Furthermore, the roller assembly also includes a roller 2, and a cover 4 is also disposed at one end of the roller 2, with the cover 4 covering and connecting the roller 2; the mounting structure also includes a roller connecting assembly, which is disposed between the cover 4 and the roller 2, for connecting the end of the roller 2 facing the cover 4 to the cover 4.

[0140] As mentioned above, the roller assembly also includes a roller 2, and a cover 4 is disposed at one end of the roller 2, with the cover 4 covering and connecting the roller 2.

[0141] Specifically, the cover 4 is disposed at one end of the roller 2 and the sludge collection tank 3, and the shape and size of the cover 4 match the shape and size of one end of the roller 2 and the sludge collection tank 3. The cover 4 can simultaneously cover and connect one end of the roller 2 and the sludge collection tank 3, and the cover 4 is detachably connected to the bracket 1, thereby realizing the detachable connection between this end of the roller 2 and the sludge collection tank 3 and the bracket 1. After the cover 4 is installed with the bracket 1, the cover 4 is located on one side of the bracket 1.

[0142] During installation, the axial direction of roller 2 is parallel to the length direction of the sludge collection tank 3. When the cover 4 closes and connects roller 2 and sludge collection tank 3, the closing direction is as follows: Figure 2 The direction indicated by the middle arrow a. By setting the cover 4, not only is the installation structure of the roller 2 and the dirt collection tank 3 at this end simplified, enabling quick installation with the bracket 1 and simplifying the installation operation, but the cover 4 also makes the overall appearance of the machine more beautiful and neat, and can prevent dust, debris and other things from entering the inside of the roller 2, affecting the operation and service life of the roller 2.

[0143] Roller 2 has a near-cylindrical structure, and its axial direction (length direction) is consistent with the length direction of the sludge collection tank 3. One end of roller 2 is installed and connected to cover 4, and the other end is installed and connected to the drive mechanism. The end of roller 2 facing cover 4 is connected to cover 4 through a roller connecting assembly.

[0144] Furthermore, the roller connecting assembly includes a connecting shaft 10 and a bearing 11. The connecting shaft 10 is connected to the roller 2, and one of the inner ring and the outer ring of the bearing 11 is fixed to the connecting shaft 10, while the other is fixed to the cover 4.

[0145] like Figure 2 , Figure 5 , Figure 12 As shown, the cover 4 has an interface 401 on the side facing the roller 2. The number of interfaces 401 matches the number of rollers 2. The interfaces 401 are connected to the ends of the rollers 2. In this embodiment, there are two interfaces 401.

[0146] The roller connecting assembly includes a connecting shaft 10 and a bearing 11, with the bearing 11 disposed within the interface 401. One of the inner and outer rings of the bearing 11 is fixed to the connecting shaft 10, and the other is fixed to the cover 4. In this embodiment, the inner ring of the bearing 11 is fixed to the connecting shaft 10, and the outer ring of the bearing 11 is fixed to the cover 4, allowing the connecting shaft 10 to rotate relative to the cover 4. The end of the connecting shaft 10 away from the bearing 11 is connected to the roller 2, thereby enabling the rotation of the roller 2 and the connecting shaft 10 relative to the cover 4.

[0147] Specifically, the end of the connecting shaft 10 furthest from the roller 2 is interference-fitted with the inner ring of the bearing 11, and the outer ring of the bearing 11 is interference-fitted with the cover 4, allowing the connecting shaft 10 to rotate relative to the cover 4. This interference-fitting connection eliminates the need for other locking structures between the connecting shaft 10, the bearing 11, and the cover 4, greatly simplifying the installation structure, improving installation efficiency, and ensuring structural reliability.

[0148] In other embodiments, the end of the connecting shaft 10 away from the roller 2 can be fixed to the outer ring of the bearing 11, while the inner ring of the bearing 11 is fixed to the cover 4.

[0149] like Figure 15 As shown, in this embodiment, a receiving cavity is provided inside the cover 4, the bearing 11 is disposed in the receiving cavity, the connecting shaft 10 is inserted into the receiving cavity and connected to the inner ring or outer ring of the bearing 11, and the mating part between the connecting shaft 10 and the receiving cavity is sealed.

[0150] Specifically, a retaining ring 25 is provided at the end of the receiving cavity away from the roller 2, and a decorative element 402 is provided on the outer surface of the cover 4. The retaining ring 25 and the decorative element 402 seal the end of the receiving cavity away from the roller 2. A second sealing element 26 and a gasket 27 are provided at the end of the receiving cavity facing the roller 2. The connecting shaft 10 passes through the second sealing element 26 and the gasket 27. The second sealing element 26 seals the mating point between the connecting shaft 10 and the receiving cavity, keeping the receiving cavity sealed and preventing external dust from entering the receiving cavity. This makes the bearing 11 less susceptible to the influence of external dust, allowing the bearing 11 to work for a long time, reducing bearing wear, improving structural reliability, and reducing the failure rate.

[0151] In addition, an insert 17 is provided inside the cover 4. The hardness of the insert 17 is higher than that of the cover 4. The insert 17 can strengthen the structural strength of the cover 4, prevent the cover 4 from deforming after long-term use, and improve its service life. A soft rubber 28 is also provided on the outside of the cover 4. The soft rubber 28 is elastic and can prevent the cover 4 from being hit when the cleaning equipment is working, and can protect the appearance of the cover 4 from scratches.

[0152] Furthermore, the roller connection assembly also includes a connector 12, through which the connecting shaft 10 is connected to the roller 2.

[0153] The roller connecting assembly also includes a connector 12, which is located at the end of the roller 2 facing the cover 4. Specifically, the connector 12 is a mop end cap. The connector 12 is fixed relative to the roller 2 in the circumferential direction and can rotate together with the roller 2. The end of the connector 12 facing the cover 4 is connected to a connecting shaft 10. The connecting shaft 10 has a shaft flatness 1001, preventing relative rotation between the connector 12 and the connecting shaft 10, thereby enabling the roller 2, connector 12, and connecting shaft 10 to rotate together.

[0154] Furthermore, the connecting shaft 10 and the connecting piece 12 are detachably connected via a snap-fit ​​structure.

[0155] When the roller 2 is used for a long time, its roller mop will wear out and need to be replaced. In this embodiment, the connecting shaft 10 and the connecting piece 12 are detachably connected by a snap-fit ​​structure to facilitate the replacement of the roller 2.

[0156] In this embodiment, as Figures 14-15 As shown, one end of the connecting shaft 10 is fixed to the inner ring of the bearing 11, and the other end is detachably connected to the connecting piece 12 through a snap-fit ​​structure. The connecting piece 12 is located at the end of the roller 2 and is fixed to the roller 2. When the roller 2 needs to be replaced, the old roller can be removed simply by disconnecting the connecting shaft 10 from the connecting piece 12 of the old roller, and then the connecting piece 12 of the new roller can be installed on the connecting shaft 10.

[0157] Furthermore, the snap-fit ​​structure includes a snap-fit ​​buckle 23 and a groove 24, one of which is disposed on the outer wall of the connecting shaft 10 and the other is disposed on the inner wall of the connector 12. The groove 24 is a flared groove, and the inner wall of the groove 24 is inclined outward. The outer wall of the snap-fit ​​23 and the inner wall of the groove 24 are inclined in the same direction.

[0158] like Figures 14-15 As shown, in this embodiment, the buckle 23 is provided on the connector 12, and the groove 24 is provided on the outer wall of the connecting shaft 10. The buckle 23 is adapted to be inserted into the groove 24 to realize the installation of the connecting shaft 10 and the connector 12.

[0159] Furthermore, to facilitate the insertion and removal of the connecting shaft 10 and the connector 12, the groove 24 is an flared groove. In the insertion / removal direction (axial direction), the inner wall of the groove 24 is inclined outwards, and the outer wall of the latch 23 is inclined in the same direction as the inner wall. The latch 23 can enter or leave the groove 24 along the inclined inner wall of the groove 24. During operation, simply pull out the connector 12 to separate the connecting shaft 10 from the connector 12 to disassemble the old roller. Then, insert the connector 12 of the new roller into the connecting shaft 10, so that the latch 23 engages with the groove 24. This latching structure enables quick disassembly and assembly of the roller, is easy to operate, significantly improves roller replacement efficiency, and facilitates user operation.

[0160] It should be noted that at least two sets of snap-fit ​​structures need to be set, and adjacent snap-fit ​​structures should be spaced apart to ensure reliable installation of the connecting shaft 10 and the connecting piece 12, so that the position of the roller 2 is fixed and the roller 2 can rotate smoothly.

[0161] In other embodiments, the buckle 23 may also be provided on the outer wall of the connecting shaft 10, while the groove 24 may be provided on the inner wall of the connector 12, as long as the buckle 23 and the groove 24 can be engaged.

[0162] Furthermore, the connecting piece 12 is fixed to the roller 2, and the connecting piece 12 and the roller 2 are relatively fixed in both the circumferential and axial directions. For example... Figure 15 As shown, the inner wall of the roller 2 is provided with a fixing buckle 29, and correspondingly, the outer wall of the connector 12 is provided with a fixing groove 30. The fixing buckle 29 and the fixing groove 30 are engaged to fix the connector 12 and the roller 2 in the axial direction. The engaging structure of the fixing buckle 29 and the fixing groove 30 is provided in at least two sets, and is spaced apart, so as to make the connection between the connector 12 and the roller 2 more stable.

[0163] Of course, in other embodiments, the fixing buckle 29 can also be set on the outer wall of the connector 12, and the fixing groove 30 can be set on the inner wall of the roller 2, as long as the fixing buckle 29 can engage with the fixing groove 30.

[0164] The inner wall of the roller 2 is also provided with a positioning post 31. The extension direction of the positioning post 31 is parallel to the axial direction of the roller 2. Correspondingly, the outer wall of the connector 12 is provided with a positioning groove 32. The extension direction of the positioning groove 32 is consistent with the extension direction of the positioning post 31. The positioning post 31 can be inserted into the positioning groove 32, so that the connector 12 and the roller 2 cannot rotate relative to each other in the circumferential direction, and the connector 12 can rotate together with the roller 2.

[0165] Of course, in other embodiments, the positioning post 31 can also be set on the outer wall of the connector 12, and the positioning groove 32 can be set on the inner wall of the roller 2, as long as the positioning post 31 and the positioning groove 32 can be inserted and matched.

[0166] Furthermore, the installation structure also includes a bracket connection structure, which is disposed between the cover 4 and the bracket 1 to connect the cover 4 and the bracket 1.

[0167] The bracket connection structure is set between the cover 4 and the bracket 1. The cover 4 can be detachably connected to the bracket 1 through the bracket connection structure, so that the cover 4 can simultaneously connect one end of the roller 2 and the sludge collection tank 3 to the bracket 1, simplifying the installation structure and improving installation efficiency and structural reliability.

[0168] like Figures 3-6 As shown, the bracket connection structure includes a snap-fit ​​member 13 and a snap-fit ​​hole 14, one of which is disposed on the cover 4 and the other on the bracket 1. In this embodiment, the snap-fit ​​member 13 is disposed on the side of the cover 4 facing the roller 2 and protrudes from the cover 4, while the snap-fit ​​hole 14 is disposed on the side of the bracket 1 facing the cover 4. The snap-fit ​​member 13 is adapted to be inserted into the snap-fit ​​hole 14 to achieve the installation connection between the cover 4 and the bracket 1.

[0169] To prevent twisting after the snap-fit ​​component 13 is engaged with the snap-fit ​​hole 14, the snap-fit ​​component 13 has a T-shaped structure, and the shape and size of the snap-fit ​​hole 14 match the shape and size of the snap-fit ​​component 13. After the snap-fit ​​component 13 is engaged with the snap-fit ​​hole 14, the snap-fit ​​component 13 and the snap-fit ​​hole 14 are tightly fitted together, and the snap-fit ​​component 13 cannot rotate relative to the snap-fit ​​hole 14, thereby achieving a reliable connection between the cover 4 and the bracket 1. This bracket connection structure can achieve reliable installation of the cover 4 and the bracket 1 even without other locking structures, simplifying the installation structure, reducing manufacturing costs, and is also convenient to operate and has high assembly efficiency.

[0170] Of course, in order to ensure the connection strength between the cover 4 and the bracket 1, after the snap-fit ​​13 is snapped into the snap-fit ​​hole 14, so that the cover 4 cannot be pulled out of the bracket 1, a locking mechanism can also be added between the cover 4 and the bracket 1 to enhance reliability.

[0171] In other embodiments, the snap-fit ​​element 13 can also be disposed on the bracket 1, and the snap-fit ​​hole 14 can be disposed on the cover 4, as long as the snap-fit ​​element 13 can snap into the snap-fit ​​hole 14.

[0172] Furthermore, the cleaning equipment also includes a drive unit 15, and the mounting structure also includes a rotating connection structure, which is located at the end of the roller 2 away from the cover 4, for connecting the drive unit 15 and the roller 2.

[0173] The cleaning equipment has a drive mechanism, which includes a drive element 15 for driving the roller 2 to rotate to achieve the cleaning process. The end of the roller 2 facing the cover 4 is mounted and connected to the cover 4, and the end of the roller 2 away from the cover 4 is connected to the drive element 15.

[0174] A rotatable connection structure is provided between the roller 2 and the driving component 15 to achieve the connection between the roller 2 and the driving component 15. In this embodiment, the driving component 15 includes a motor and a gearbox that are connected by transmission, and the output shaft of the driving component 15 is specifically the gearbox output shaft 33.

[0175] Furthermore, the rotating connection structure includes an adapter 16, one end of which is fixed to the output shaft of the drive member 15, and the other end is fixed to the roller 2.

[0176] like Figures 1-2 As shown, the rotating connection structure includes an adapter 16. One end of the adapter 16 is connected to the output shaft of the drive 15, and the other end is connected to the roller 2. The adapter 16 and the roller 2 will not rotate relative to each other, nor will the adapter 16 and the roller 2 move relative to each other in the axial direction. This rotating connection structure is simple, which facilitates the connection between the drive and the roller, simplifies the installation structure, and improves installation efficiency.

[0177] In this embodiment, the adapter 16 and the roller 2 are connected by a rotation limiting structure so that the adapter 16 and the roller 2 can be limited in the circumferential and axial directions. Under the drive of the drive member 15, the adapter 16 and the roller 2 rotate together.

[0178] Furthermore, the rotation limiting structure includes a rotation limiting groove 18 and a rotation limiting protrusion 19 that engage with each other. One of the rotation limiting groove 18 and the rotation limiting protrusion 19 is disposed on the outer wall of the adapter 16, and the other is disposed on the inner wall of the roller 2.

[0179] like Figure 13 As shown, the rotation limiting structure includes a rotation limiting groove 18 and a rotation limiting protrusion 19 that engage with each other. The rotation limiting groove 18 can be disposed on the outer wall of the adapter 16 or on the inner wall of the roller 2. Correspondingly, the rotation limiting protrusion 19 can be disposed on the inner wall of the roller 2 or on the outer wall of the adapter 16. In this embodiment, the rotation limiting groove 18 is disposed on the inner wall of the roller 2, and the rotation limiting protrusion 19 is disposed on the outer wall of the adapter 16. The rotation limiting protrusion 19 is adapted to be inserted into the rotation limiting groove 18 and engage with the rotation limiting groove 18 to achieve rotation limiting between the adapter 16 and the roller 2.

[0180] In other embodiments, the rotation limiting groove 18 may also be provided on the outer wall of the adapter 16, and the rotation limiting protrusion 19 may be provided on the inner wall of the roller 2, as long as the rotation limiting groove 18 and the rotation limiting protrusion 19 can be engaged.

[0181] At least two rotation limiting grooves 18 and rotation limiting protrusions 19 are provided. At least two rotation limiting grooves 18 are circumferentially spaced around one of the transition member 16 and the roller 2, and at least two rotation limiting protrusions 19 are circumferentially spaced around the other of the transition member 16 and the roller 2.

[0182] In this embodiment, four rotation limiting grooves 18 are provided, and the four rotation limiting grooves 18 are circumferentially spaced around the inner wall of the roller 2. Four rotation limiting protrusions 19 are provided, and the four rotation limiting protrusions 19 are circumferentially spaced around the outer wall of the adapter 16.

[0183] In other embodiments, the number of rotation limiting grooves 18 and rotation limiting protrusions 19 may be two, three, five, etc. Furthermore, the number of rotation limiting grooves 18 and rotation limiting protrusions 19 may be the same or different. To achieve a snap-fit ​​engagement between the rotation limiting grooves 18 and rotation limiting protrusions 19, the number of rotation limiting grooves 18 may be greater than or equal to the number of rotation limiting protrusions 19. In this embodiment, the number of rotation limiting grooves 18 is equal to the number of rotation limiting protrusions 19, and there are four of each type.

[0184] In other embodiments, the number of rotation limiting grooves 18 may be greater than the number of rotation limiting protrusions 19.

[0185] Understandably, the more rotation limit grooves 18 and rotation limit protrusions 19 are provided, the stronger the connection between them, and the more reliable the rotation limit between the adapter 16 and the roller 2.

[0186] Furthermore, the rotation limiting structure also includes a first sealing element 20, which is sleeved on the rotation limiting protrusion 19, and the rotation limiting protrusion 19 is engaged in the rotation limiting groove 18 by the first sealing element 20.

[0187] The rotation limiting structure also includes a first sealing element 20. A rotation limiting protrusion 19 protrudes from the adapter 16 and has a columnar structure. The first sealing element 20 is sleeved on the rotation limiting protrusion 19 and covers its outer wall. The rotation limiting protrusion 19 is engaged within the rotation limiting groove 18 by the first sealing element 20. After entering the rotation limiting groove 18, the first sealing element 20 is deformed by the inner wall of the rotation limiting groove 18, reliably engaging the rotation limiting protrusion 19 within the rotation limiting groove 18. The first sealing element 20 is a sealing ring and can be made of elastic materials such as rubber.

[0188] Furthermore, the first seal 20 is interference-fitted with the first seal 20.

[0189] In this embodiment, a first sealing element 20 is sleeved on the outside of the rotation limiting protrusion 19, and the first sealing element 20 is interference-fitted with the first sealing element 20. The first sealing element 20 can reliably engage the rotation limiting groove 18 and the rotation limiting protrusion 19 through deformation. There is a gap between the ends of the rotation limiting groove 18 and the rotation limiting protrusion 19, so that the rotation limiting groove 18 and the rotation limiting protrusion 19 will not contact or interfere with each other, thereby improving the adaptability of the structure, reducing the structural wear of the adapter 16 and the roller 2, and ensuring the service life.

[0190] Furthermore, when installing the roller assembly, the installation sequence is as follows: first, connect one end of the roller 2 to the cover 4; then, connect the cover 4 to the bracket 1; simultaneously, connect the other end of the roller 2 to the bracket 1; and finally, install the dirt collection tank 3 (otherwise, the various structures of the roller assembly cannot be locked together, and normal cleaning work cannot be performed). Therefore, the positioning detection mechanism in this embodiment can not only detect whether the dirt collection tank 3 is installed in place, but also detect the safety status of the roller 2.

[0191] Specifically, if the sludge collection tank 3 is not installed, or if the sludge collection tank 3 cannot be installed due to the absence of the roller 2 and cover 4, the detection element 35 of the positioning detection mechanism will not detect the signal of the trigger element 36 and will issue an alarm. If the sludge collection tank 3 is installed in place, the detection element 35 will be able to detect the signal of the trigger element 36, at which point both the roller 2 and the sludge collection tank 3 are installed in place. Thus, by setting up a positioning detection mechanism, it is possible to simultaneously detect whether both the roller 2 and the sludge collection tank 3 are installed in place.

[0192] This embodiment also provides a roller assembly, including a bracket 1, a roller 2 and a dirt collection tank 3, wherein the roller 2 and the dirt collection tank 3 are installed by the installation structure described above.

[0193] In this embodiment, two rollers 2 are provided, arranged in parallel. Optionally, the two rollers 2 have the same length and diameter, but are made of different materials. For example, the front roller uses a mop cloth with relatively strong friction and cleaning ability, such as nylon velvet; the rear roller uses a mop cloth with relatively strong water absorption, such as high-density velvet. In this dual-roller assembly, the front roller has strong cleaning power but poor water absorption, resulting in more water stains after mopping. The rear roller absorbs the water and wipes away the water stains, achieving the best cleaning effect.

[0194] The sludge collection trough 3 is located between the two rollers 2, and the length direction of the sludge collection trough 3 is parallel to the axial direction of the roller 2. One end of the roller 2 and the sludge collection trough 3 can be installed together on the bracket 1 through the cover of the installation structure. The installation process is simple and quick, which can significantly improve the replacement efficiency of the roller 2 and the sludge collection trough 3, and also helps to reduce manufacturing costs. Furthermore, because this installation structure is relatively simple in its overall structure, it is not easy to be damaged, has good structural stability, and high reliability, which helps to reduce the failure rate of the roller assembly, ensure service life, and improve the user experience.

[0195] like Figure 16 The figure shows an installation structure according to another embodiment of this application. The difference between this embodiment and the previous embodiment is that the connection method of the cover 4, bearing 11 and connecting shaft 10 is different.

[0196] In this embodiment, a receiving cavity is provided inside the cover 4, and the bearing 11 is disposed in the receiving cavity. The connecting shaft 10 is inserted into the receiving cavity and connected to the inner ring or outer ring of the bearing 11. However, the mating part between the connecting shaft 10 and the receiving cavity is not sealed in order to simplify the structure and reduce manufacturing costs.

[0197] At this time, a snap fastener 34 is provided on the side wall of the cavity of the cover 4. The side of the bearing 11 facing the roller 2 abuts against the snap fastener 34 to press the bearing 11 and prevent the bearing 11 from moving or falling out. The inner ring of the bearing 11 is tightly fitted with the connecting shaft 10, and the outer ring of the bearing 11 is interference-fitted with the cover 4. The connecting piece 12 of the roller 2 is tightly fitted with the connecting shaft 10, so that the roller 2 and its connecting piece 12 can rotate relative to the cover 4. In this structure, the connecting piece 12 of the roller 2 and the cover 4 cannot be disassembled. When the roller 2 needs to be replaced, the cover 4 must be replaced together.

[0198] This embodiment also provides a cleaning device, including the mounting structure as described above or including the roller assembly as described above.

[0199] The cleaning equipment includes the installation structure described above or the roller assembly described above. The cover 4 of the installation structure can simultaneously install and remove one end of the roller 2 and the dirt collection tank 3 from the bracket 1, which greatly simplifies the installation structure of the roller 2 and the dirt collection tank 3. The installation process is simple and quick, which can significantly improve the replacement efficiency of the roller 2 and the dirt collection tank 3, and also helps to reduce manufacturing costs. Furthermore, because the overall structure of this installation structure is relatively simple, it is not easily damaged, has good structural stability, and high reliability, which helps to reduce the failure rate of the roller assembly, ensure service life, and improve the user experience.

[0200] Of course, this cleaning equipment also has other structural components that are present in existing cleaning equipment, such as a clean water tank, a scraper, and a wastewater tank, which will not be elaborated here.

[0201] Furthermore, the cleaning equipment is one of the following: a sweeping robot, a mopping robot, a floor scrubbing robot, and a cleaning robot. For example, a sweeping robot, a handheld floor scrubbing robot, and a fully automatic floor scrubbing robot. In this embodiment, the cleaning equipment is a cleaning robot.

[0202] When this cleaning equipment is working, the double-roller mop rotates inward to mop the floor, the clean water tank drains water to clean the roller mop, and the scraper removes the dirty wastewater from the roller mop. The scraped wastewater flows into the sludge collection tank 3 and is then pumped away by the wastewater tank, thus completing the cleaning process.

[0203] The installation process of the cleaning equipment roller 2 and the dirt collection tank 3 in this embodiment will be described below with reference to the accompanying drawings:

[0204] First, align one end of roller 2 with the interface 401 of cover 4, so that the connector 12 at the end of roller 2 is interference-fitted with the inner ring of bearing 11 inside cover 4.

[0205] Then, align the snap-fit ​​piece 13 on the cover 4 with the snap-fit ​​hole 14 on the bracket 1, so that the snap-fit ​​piece 13 is snapped into the snap-fit ​​hole 14. At this time, one end of the cover 4 and the roller 2 are installed and fixed to the bracket 1.

[0206] Next, install the end of the roller 2 away from the cover 4 with the adapter 16, so that the rotation limiting protrusion 19 is engaged in the rotation limiting groove 18. At this point, the roller 2, cover 4, and bracket 1 are installed.

[0207] Then, insert the plug 21 at the end of the sludge collection tank 3 away from the cover 4 into the socket 22 on the bracket 1. At the same time, move the end of the sludge collection tank 3 with the locking member 8 close to the cover 4, move the locking member 8 away from the cover 4, and compress the elastic member 9 to avoid the installation path until the end of the sludge collection tank 3 enters the insertion space between the first limiting member 5 and the second limiting member 7. Release the locking member 8 and reset the elastic member 9. The locking member 8 is inserted into the above insertion space. Under the action of gravity, the lower surface of the locking member 8 abuts against the upper surface of the second limiting member 7, thereby limiting the sludge collection tank 3 in the first part of the second direction. At the same time, the first limiting member 5 is inserted into the first limiting groove 6. The first limiting groove 6 limits the first limiting member 5 in the first direction and the second part of the second direction, thereby limiting the sludge collection tank 3 in the first direction and the second part of the second direction by the cover 4. At this point, the sludge collection tank 3, the cover 4, and the bracket 1 are installed.

[0208] If the detection component 35 of the detection mechanism issues an alarm during the installation of the sludge collection tank 3, it indicates that the sludge collection tank 3 is not installed properly. After hearing the alarm, the user can check the installation status of the roller 2 and the sludge collection tank 3.

[0209] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
