Description

Technical Field

[0001] This application relates to the field of cleaning equipment, and more particularly to a floor brush device, cleaning equipment, and cleaning system. Background Technology

[0002] In modern household and commercial cleaning equipment, floor scrubbers have gradually become the mainstream product in the market due to their efficient cleaning capabilities and convenient operation. During the use of floor scrubbers, the cleaning and drying of the roller brush has always been a key concern for users.

[0003] Traditional floor scrubbers typically use fixed drying time settings. While this approach is simple, it cannot adapt to the needs of different environments and usage conditions. For example, in a wet environment, the roller brush may require a longer drying time, while in a dry environment, a fixed drying time may lead to unnecessary energy waste.

[0004] In existing technology, the motor power corresponding to the load current generated by the rotating roller brush is detected, and the moisture content in the roller brush is determined based on different motor power values, thereby determining the degree of drying of the roller brush. However, after a period of use, due to roller brush wear and other reasons, the above method may result in a large error in determining the moisture content in the roller brush, causing the roller brush to stop drying while still damp, which can easily lead to bacterial growth. Summary of the Invention

[0005] This application provides a floor brush device, cleaning equipment, and cleaning system, which allows the detection element to extend into the working space and directly contact the bristles of the roller brush mechanism. The moisture content of the roller brush mechanism is determined by detecting the current intensity, resulting in a more accurate judgment.

[0006] In a first aspect, embodiments of this application provide a floor brush device for cleaning equipment. The cleaning equipment is equipped with a power supply device and includes: a floor brush housing defining a working space; a roller brush mechanism disposed in the working space, at least a portion of the roller brush mechanism being rotatable relative to the floor brush housing for cleaning a surface to be cleaned; and an electrode detection device including two detection elements, the two detection elements being spaced apart from each other in the floor brush housing and extending into the working space to contact the bristles of the roller brush mechanism, and the two detection elements being electrically connected to the power supply device.

[0007] This utility model's floor brush device, because the electrode detection device's detection element extends into the working space and directly contacts the brush bristles, when the bristles contain water, it creates a conductive connection between the two detection elements, forming a complete circuit through the power supply device. The moisture content of the roller brush mechanism can be determined by detecting the current in the circuit: the amount of moisture on the bristles directly affects the resistance value between the two detection elements. As the roller brush mechanism dries, the moisture content gradually decreases, and the resistance value between the two detection elements gradually increases. Thus, when the bristles are completely dried or the moisture content is extremely low, the resistance value between the two detection elements is high, and the current in the circuit is very small or close to zero (less than the set drying threshold). At this point, it can be determined that the roller brush mechanism has finished drying, and drying can be stopped. In other words, when the current in the circuit is not less than the drying threshold, it can be determined that the roller brush mechanism is in a damp state and needs to continue drying. The wear of the roller brush mechanism has little impact on the detection results, and the drying time can be adjusted according to the condition of the roller brush mechanism to achieve a good drying effect.

[0008] In some embodiments, the floor brush housing includes: a floor brush base, the working space being located on the front side of the floor brush base, and the roller brush mechanism being connected to the floor brush base; a water tank assembly being disposed on the upper side of the floor brush base and the working space, a portion of the surface of the water tank assembly forming the inner wall of the working space; and a detection element being disposed on the side surface of at least one of the water tank assembly and the floor brush base facing the working space.

[0009] The water tank assembly is integrated into the base of the floor brush, making it convenient and quick to supply water to the workspace for cleaning the roller brush assembly.

[0010] According to some embodiments of the present invention, the water tank assembly includes: a clean water tank, including a lower tank and an upper tank, the lower tank and the upper tank being connected to each other and jointly defining a water storage cavity, the lower tank including a first area connected to the floor brush base and a second area located on the upper side of the roller brush mechanism, and all the detection elements are disposed in the second area.

[0011] In this way, the clean water tank is installed by matching the base of the floor brush through the first area, making water changes convenient. The second area extends above the roller brush mechanism, which helps to protect the roller brush mechanism and reduce the possibility of damage from impacts.

[0012] According to some embodiments of the present invention, the second region is provided with a fixing hole communicating with the working space, the detection element is fixed to the fixing hole and extends into the working space through the fixing hole to contact the bristles of the roller brush mechanism.

[0013] This allows the test piece to extend into the working space, ensuring that the test piece and the bristles of the roller brush mechanism remain in constant contact, thus ensuring accurate moisture content measurement of the roller brush mechanism and guaranteeing the drying effect of the roller brush.

[0014] According to some embodiments of the present invention, it further includes: a conductive connection device disposed in at least one of the first region and the floor brush base, the conductive connection device being used to connect the detection element and the power supply device.

[0015] In this way, the conductive device connects the detection component and the power supply, ensuring the accuracy of the detection results.

[0016] According to some embodiments of the present invention, the conductive connection device includes: a first conductive module disposed in the first region and electrically connected to the detection element; and a second conductive module disposed in the floor brush base and electrically connected to the first conductive module and the power supply device respectively.

[0017] This makes the wiring distribution of the conductive connection device more reasonable. After the user disassembles the water tank to add water and then reinstalls it on the floor brush base, the detection component and the power supply device can still maintain conductivity, which improves the reliability of the detection process.

[0018] According to some embodiments of the present invention, the first region is provided with a through hole, and the first conductive module includes: a mounting cylinder, which is fixedly disposed at the through hole, and the mounting cylinder defines a mounting cavity; and two conductive pillars corresponding to the detection element, the first end of the conductive pillar being located in the mounting cavity and connected to the corresponding detection element through a conductive wire, and the second end of the conductive pillar passing through the bottom wall of the mounting cylinder to be electrically connected to the second conductive module.

[0019] By cooperating with the conductive post and the second conductive module, the part of the conductive connection device located on the water tank and the second conductive module on the floor brush base are matched to ensure that after the water tank is disassembled for maintenance or water filling, the water tank is installed on the floor brush base, and there is a reliable electrical connection between the detection component and the power supply device.

[0020] According to some embodiments of the present invention, the top of the mounting cavity is open to form a mounting opening, and the upper housing is adapted to cover the mounting opening to separate the mounting cavity from the water storage cavity.

[0021] This prevents water from the water storage chamber from entering the installation chamber, which could cause a short circuit between the two conductive posts, affecting the test results or even damaging the conductive posts.

[0022] According to some embodiments of the present invention, the first conductive module further includes: two conductive plates, each corresponding to one of the conductive posts, the conductive plates being fixedly disposed on the side surface of the mounting cylinder facing the floor brush base, and connected to the corresponding conductive post and the second conductive module.

[0023] By setting up a conductive plate, the conductive area between the first conductive module and the second conductive module can be increased, thereby improving the reliability of the conductive connection between the first conductive module and the second conductive module.

[0024] According to some embodiments of the present invention, it further includes: an in-situ detection resistor, the two ends of which are respectively connected to the two conductive posts.

[0025] The in-situ detection resistor forms an in-situ detection loop in parallel with the loop that detects the water content of the roller brush assembly. When the clean water tank is correctly installed, the in-situ detection loop is activated, improving the reliability of the clean water tank installation. When the water tank assembly is not dispensing water, the in-situ detection resistor allows the user to determine whether the clean water tank is low on water or has shifted position, facilitating timely water replenishment or adjustment of the tank's position.

[0026] According to some embodiments of the present invention, the side wall of the mounting cylinder is provided with a connecting lug, the connecting lug is provided with a first connecting hole, and the periphery of the through hole is provided with a second connecting hole. The mounting cylinder and the lower housing are connected by fasteners passing through the first connecting hole and the second connecting hole.

[0027] This allows the first conductive module to be fixed on the lower housing, resulting in a simple structure and easy installation, facilitating the inspection and replacement of components within the first conductive module.

[0028] According to some embodiments of the present invention, the mounting cylinder is sealed to the through hole; and / or, the mounting cylinder is sealed to the upper housing.

[0029] This improves the sealing performance of the first conductive module, preventing moisture from entering the mounting cylinder and thus extending the service life of the first conductive module.

[0030] According to some embodiments of this utility model, the second conductive module and the first conductive module are arranged opposite to each other along the thickness direction of the floor brush housing; the second conductive module includes: a package body, fixedly disposed on the floor brush base, the package body having an assembly hole extending along the thickness direction of the floor brush housing; and two conductive needles corresponding to the detection element, the conductive needles passing through the assembly hole, the conductive needles having a first connecting end and a second connecting end exposed in the assembly hole, the first connecting end being connected to the power supply device, and the second connecting end being connected to the first conductive module.

[0031] When the clean water tank is installed on the floor brush base, the power supply device and the first conductive module are connected through the conductive pin. The structure is simple and the operation is convenient.

[0032] According to some embodiments of the present invention, the conductive needle is movable along the thickness direction of the floor brush housing, and the second conductive module further includes: an elastic reset member disposed in the assembly hole and sleeved on the outside of the conductive needle, wherein the two ends of the elastic reset member are respectively connected to the package body and the conductive needle.

[0033] Thus, when the clean water tank is installed on the floor brush base, the first conductive module squeezes the conductive pin to move, preventing damage to the conductive pin. The elastic reset component applies a force to the conductive pin toward the first conductive module, making the electrical connection between the conductive pin and the first conductive module more reliable.

[0034] According to some embodiments of the present invention, the package includes: a first package and a second package, the first package and the second package are connected to each other, the mounting hole passes through the first package and the second package, a portion of the conductive needle passes through the first package and another portion passes through the second package.

[0035] In this way, when the components of the second conductive module need to be inspected or replaced, only the package body needs to be removed, and the first and second packages body needs to be opened for inspection and replacement. There is no need to replace the entire second conductive module, which helps to save maintenance costs and thus improve user satisfaction.

[0036] According to some embodiments of the present invention, the first package body and the second package body are sealed together; and / or, the conductive pin is sealed together with the assembly hole.

[0037] This keeps the second conductive module in a relatively sealed environment, preventing moisture or dirt from entering the package and thus extending its service life.

[0038] Secondly, embodiments of this application also provide a cleaning device, including: a main unit, including a body and a power supply device disposed on the body; the aforementioned floor brush device, wherein the electrode detection device of the floor brush device is connected to the power supply device.

[0039] The cleaning equipment of this utility model, by using the above-mentioned floor brush device, allows for more accurate judgment of the moisture content of the roller brush mechanism during the drying process, which helps users to accurately grasp the dryness of the roller brush mechanism and improves user satisfaction.

[0040] Thirdly, embodiments of this application also provide a cleaning system, including: a cleaning base station; and the aforementioned cleaning equipment, wherein the cleaning base station is at least configured to clean the floor brush assembly of the cleaning equipment.

[0041] The cleaning system of this utility model, by using the aforementioned cleaning equipment, allows the cleaning base station to clean the floor brush and then dry the roller brush mechanism of the floor brush device. Users can accurately control the degree of dryness of the roller brush mechanism and set the corresponding drying temperature and drying time, which helps to improve user satisfaction.

[0070] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0071] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0072] Existing floor scrubbers determine the moisture content of the brush by measuring the motor power corresponding to the load current generated by the brush rotation, and thus determining the degree of drying. However, after a period of use, due to brush wear and other factors, this method of determining the moisture content of the brush may have significant errors, causing the brush to stop drying while still damp, which can easily lead to bacterial growth.

[0073] In view of this, embodiments of this application provide a floor brush device, cleaning equipment, and cleaning system, which allows the detection element to extend into the working space and directly contact the bristles of the roller brush mechanism, and determines the moisture content of the roller brush mechanism by detecting the current intensity, making the judgment result more accurate.

[0074] refer to Figures 1 to 11 In the first aspect, embodiments of this application provide a floor brush device 100, which can be used in cleaning equipment. The cleaning equipment is equipped with a power supply device, which supplies power to the floor brush device 100.

[0075] The floor brush device 100 may include: a floor brush housing 10, a roller brush mechanism 20, and an electrode detection device.

[0076] refer to Figure 1 , Figure 2 and Figure 5 The floor brush housing 10 defines a working space 11, within which a roller brush mechanism 20 is disposed. At least a portion of the roller brush mechanism 20 (such as a roller with bristles) is rotatable relative to the floor brush housing 10. As the floor brush device 100 moves along the cleaning surface, the roller rotates relative to it, cleaning the surface to be cleaned. During the cleaning process, water is often sprayed onto the roller to keep it clean, thereby ensuring the cleaning effect of the floor brush device 100. After cleaning, the roller brush mechanism 20 needs to be cleaned and dried to prevent bacterial growth.

[0077] The electrode detection device may include two detection elements 31, which are spaced apart in the brush housing 10 and extend into the working space 11 to contact the bristles of the roller brush mechanism 20. The two detection elements 31 are also electrically connected to the power supply device, corresponding to the positive and negative terminals of the power supply device.

[0078] Understandably, in order to detect as much moisture content as possible on the roller brush mechanism 20, the two detection elements 31 can be located at both ends of the roller of the roller brush mechanism 20 along its length. The detection elements 31 can abut against the roller; in other words, the contact point between the detection elements 31 and the bristles can be the root of the bristles that are connected to the roller. This can reduce the impact of bristle wear on the detection results of the detection elements 31 during the use of the floor brush device 100.

[0079] The floor brush device 100 of this invention, because the detection element 31 of the electrode detection device extends into the working space 11 and directly contacts the brush bristles, when the brush bristles contain water, conduction occurs between the two detection elements 31, forming a complete circuit through the power supply device. The moisture content of the roller brush mechanism 20 can be determined by detecting the current in the circuit: the amount of moisture on the brush bristles directly affects the resistance value between the two detection elements 31. As the roller brush mechanism 20 dries, the moisture content gradually decreases, and the resistance value between the two detection elements 31 gradually increases. Thus, when the brush bristles are completely dried or the moisture content is extremely low, the resistance value between the two detection elements 31 is high, and the current in the circuit is very small or close to zero. A drying threshold can be set. When the current in the circuit is less than the drying threshold, it can be determined that the roller brush mechanism 20 has been dried and drying can be stopped. In other words, when the current in the circuit is not less than the drying threshold, it can be determined that the roller brush mechanism 20 is in a damp state and needs to continue drying. The wear of the roller brush mechanism 20 has little impact on the test results. The drying time can be adjusted according to the condition of the roller brush mechanism 20 to achieve a good drying effect.

[0080] refer to Figure 1 and Figure 2 In some embodiments, the floor brush housing 10 may include a floor brush base 12 and a water tank assembly 13. The workspace 11 is located in front of the floor brush base 12, and the roller brush mechanism 20 is connected to the floor brush base 12. The floor brush base 12 moves back and forth, and the roller brush mechanism 20 cleans the cleaning surface.

[0081] The water tank assembly 13 is located on the upper side of the floor brush base 12 and the working space 11. This results in a high degree of integration of the floor brush device 100, which helps to reduce the space occupied by the device, facilitates storage, and thus improves user satisfaction. Part of the surface of the water tank assembly 13 (such as the second region 1311b described later) forms the inner wall of the working space 11, which improves the structural utilization of the water tank assembly 13 and reduces the equipment cost of the floor brush device 100.

[0082] The detection element 31 can be disposed on the surface of at least one of the water tank assembly 13 and the brush base 12 facing the working space 11. For example, both detection elements 31 can be disposed on the surface of the water tank assembly 13 facing the working space 11, or both detection elements 31 can be disposed on the surface of the brush base 12 facing the working space 11, or one of the two detection elements 31 can be disposed on the surface of the water tank assembly 13 facing the working space 11 and the other on the surface of the brush base 12 facing the working space 11, to detect the water content on the roller brush component in the working space 11. The detection process is convenient, occupies little working space 11, and helps to save equipment costs.

[0083] refer to Figure 2 , Figure 3 and Figure 5 According to some embodiments of this utility model, the water tank assembly 13 may include a clean water tank 131, which may include a lower tank 1311 and an upper tank 1312. The lower tank 1311 and the upper tank 1312 are connected to each other and together define a water storage chamber. During the cleaning process of the floor brush device 100, a suction pump installed on the floor brush base 12 pumps the cleaning water in the water storage chamber to the roller brush component to ensure the cleaning effect of the floor brush device 100.

[0084] The lower housing 1311 may include a first region 1311a and a second region 1311b. The first region 1311a is connected to the floor brush base 12, and the second region 1311b is located above the roller brush mechanism 20. The detection elements 31 can be uniformly disposed in the second region 1311b. Thus, the clean water tank 131 is installed by matching the floor brush base 12 through the first region 1311a, facilitating water changes. The second region 1311b extends above the roller brush mechanism 20, which helps protect the roller brush mechanism 20 and reduces the risk of damage from impacts.

[0085] Understandably, the process of adding cleaning fluid to the clean water tank 131 can be as follows: the user removes the clean water tank 131, moves it to the water source, opens the upper tank 1312 to fill the water storage chamber, then closes the upper tank 1312 and reinstalls the clean water tank 131 onto the floor brush base 12. Alternatively, the user can directly open the upper tank 1312, fill the water storage chamber, and then close the upper tank 1312.

[0086] Optionally, the water tank assembly 13 may also include a wastewater tank for recycling wastewater generated during the cleaning process of the floor brush device 100. The wastewater tank may also be located on the floor brush device 100, or it may be located on other structures of the cleaning equipment (such as the main unit).

[0087] refer to Figure 6 According to some embodiments of this utility model, the second region 1311b is provided with a fixing hole 1311c communicating with the working space 11. The detection element 31 is fixed in the fixing hole 1311c. The fixing method of the detection element 31 can be snap-fit, adhesive, or fixedly connected to the second region 1311b through a fixing element. The detection element 31 extends into the working space 11 through the fixing hole 1311c and contacts the bristles of the roller brush mechanism 20, thereby detecting the moisture content of the roller brush mechanism 20. In this way, the detection element 31 can extend into the working space 11, ensuring that the detection element 31 and the bristles of the roller brush mechanism 20 always maintain contact, so that the detected moisture content of the roller brush mechanism 20 is accurate, ensuring the drying effect of the roller brush.

[0088] refer to Figure 3 and Figure 4According to some embodiments of this utility model, the floor brush device 100 may further include a conductive connection device 14. The conductive connection device 14 is disposed in at least one of the first region 1311a and the floor brush base 12, and is used to connect the detection element 31 and the power supply device. For example, the conductive connection device 14 may be disposed in the first region 1311a, or it may be disposed in the floor brush base 12. Alternatively, since the water tank 131 and the floor brush base 12 may be detachably connected, in order to ensure a stable electrical connection between the detection element 31 on the water tank 131 and the power supply device of the floor brush device 100, part of the structure of the conductive connection device 14 may be located in the first region 1311a, and another part may be located in the second region 1311b. When the water tank 131 is installed on the floor brush base 12, the two parts of the conductive connection device 14 cooperate to make the detection element 31 and the power supply device conductive. In this way, the conductive device makes the detection element 31 and the power supply device conductive, ensuring the accuracy of the detection results.

[0089] Continue to refer to Figure 4 According to some embodiments of this utility model, the conductive connection device 14 may include a first conductive module 141 and a second conductive module 142. The first conductive module 141 is disposed in the first region 1311a and can be electrically connected to the detection element 31. The second conductive module 142 is disposed on the floor brush base 12 and is electrically connected to both the first conductive module 141 and the power supply device. This makes the wiring distribution of the conductive connection device 14 more reasonable. Even after the user disassembles the water tank 131 to add water and then reinstalls it on the floor brush base 12, the detection element 31 can still maintain conductivity with the power supply device, improving the reliability of the detection results.

[0090] Continue to refer to Figure 6 , Figure 7 and Figure 8 According to some embodiments of the present invention, the first region 1311a is provided with a through hole 1131d, and the first conductive module 141 may include: a mounting cylinder 1411 and a conductive post 1412. The mounting cylinder 1411 is fixedly disposed at the through hole 1131d, and the mounting cylinder 1411 defines a mounting cavity.

[0091] There are two conductive posts 1412 corresponding to the detection element 31. The first end 1412a of the conductive post 1412 is located in the mounting cavity and is connected to the corresponding detection element 31 through a conductive wire. The second end 1412b of the conductive post 1412 passes through the bottom wall of the mounting cylinder 1411 and is electrically connected to the second conductive module 142.

[0092] The conductive post 1412 cooperates with the second conductive module 142 to ensure that the conductive connection device 14 is located between the first conductive module 141 on the clean water tank 131 and the second conductive module 142 on the floor brush base 12. This ensures that after the clean water tank 131 is disassembled for maintenance or water filling, the clean water tank 131 is installed on the floor brush base 12, and the detection component 31 has a reliable electrical connection with the power supply device.

[0093] According to some embodiments of this utility model, the top of the mounting cavity is open to form a mounting port, so as to facilitate the installation of the conductive post 1412 from the mounting port into the mounting cavity. The upper housing 1312 is adapted to cover the mounting port to separate the mounting cavity from the water storage cavity. In this way, water in the water storage cavity is prevented from entering the mounting cavity, which could cause a short circuit between the two conductive posts 1412, affecting the detection results, or even causing damage to the conductive post 1412.

[0094] refer to Figure 4 According to some embodiments of the present invention, the first conductive module 141 may further include a conductive piece 1413, which consists of two conductive pieces 1413 corresponding one-to-one with the conductive post 1412. The conductive pieces 1413 are fixedly disposed on the side surface of the mounting cylinder 1411 facing the floor brush base 12, and are connected to the corresponding conductive post 1412 and the second conductive module 142.

[0095] For example, the conductive piece 1413 may have a conductive portion protruding towards the brush base 12. The second end 1412b of the conductive post 1412 contacts the surface of the conductive piece 1413 away from the brush base 12. The conductive structure of the second conductive module 142 (such as the conductive pin 1422 described later) abuts against the conductive portion, thereby making the first conductive module 141 and the second conductive module 142 conductively connected. By providing the conductive piece 1413, the conductive area between the first conductive module 141 and the second conductive module 142 can be increased, improving the reliability of the conductive connection between the first conductive module 141 and the second conductive module 142.

[0096] refer to Figure 8 According to some embodiments of the present invention, the first conductive module 141 may further include an in-situ detection resistor 1414, the two ends of which are respectively connected to two conductive posts 1412.

[0097] The working principle of the in-situ detection resistor 1414 is as follows: the in-situ detection resistor 1414 can form an in-situ detection circuit in parallel with the circuit of the detection element 31 for detecting the water content of the roller brush assembly. When the clean water tank 131 is correctly installed, the in-situ detection circuit is connected to improve the reliability of the installation of the clean water tank 131.

[0098] Furthermore, if the water tank assembly 13 fails to dispense water during the cleaning process, the user can determine whether the issue stems from a lack of water in the clean water tank 131 or a misalignment of the tank by checking the continuity of the on-line detection circuit. If the on-line detection circuit is active, the clean water tank 131 is correctly installed, and if it is low on water, the user can add water. If the on-line detection circuit is not active, the clean water tank 131 has misaligned, and the user needs to adjust its position. This improves the user experience.

[0099] Continue to refer to Figure 6 and Figure 8 According to some embodiments of this utility model, the side wall of the mounting cylinder 1411 is provided with a connecting lug 1411a, the connecting lug 1411a is provided with a first connecting hole 1411b, and the periphery of the through hole 1131d is provided with a second connecting hole 1131e. The mounting cylinder 1411 and the lower housing 1311 are connected by fasteners passing through the first connecting hole 1411b and the second connecting hole 1131e. In this way, the first conductive module 141 is fixedly mounted on the lower housing 1311, which has a simple structure and is easy to install, so as to facilitate the inspection and replacement of the components inside the first conductive module 141.

[0100] Optionally, in other embodiments of this application, the fastener can be directly formed as a fixing post fixed around the through hole 1131d, and the first connecting hole 1411b can be aligned with the fixing post to realize the connection between the mounting cylinder 1411 and the lower housing 1311.

[0101] According to some embodiments of the present invention, the mounting cylinder 1411 is sealed to the through hole 1131d. For example, a sealing ring may be fitted on the outer wall of the mounting cylinder 1411. The outer ring of the sealing ring abuts against the inner wall of the through hole 1131d, and the inner wall of the sealing ring abuts against the outer wall of the mounting cylinder 1411, so as to prevent moisture from entering the mounting cylinder 1411 through the through hole 1131d.

[0102] The mounting cylinder 1411 and the upper housing 1312 are sealed together. For example, an end cap may be provided between the mounting cylinder 1411 and the upper housing 1312, covering the mounting opening. The upper housing 1312 is mounted onto the lower housing 1311, with the portion of the upper housing 1312 facing the mounting cylinder 1411 pressing against the end cap to seal the mounting cavity. Alternatively, the end cap may be directly formed on the upper housing 1312, sealing the mounting cavity when the housing is mounted onto the lower housing 1311. This improves the sealing performance of the first conductive module 141, preventing moisture from entering the mounting cylinder 1411 and thus extending the service life of the first conductive module 141.

[0103] refer to Figure 3 , Figure 4 , Figure 9 and Figure 10According to some embodiments of the present invention, the second conductive module 142 and the first conductive module 141 are arranged opposite to each other along the thickness direction of the brush housing 10. The second conductive module 142 may include a package 1421 and a conductive pin 1422. The package 1421 is fixedly disposed on the brush base 12, and the package 1421 is provided with an assembly hole that extends along the thickness direction of the brush housing 10.

[0104] There can be two conductive needles 1422 corresponding to the detection element 31. The conductive needles 1422 are inserted into the assembly hole. The conductive needles 1422 have a first connecting end 1422a and a second connecting end 1422b exposed in the assembly hole. The first connecting end 1422a is connected to the power supply device through a conductive wire, and the second connecting end 1422b is connected to the first conductive module 141.

[0105] For example, the second connection end 1422b of the conductive needle 1422 abuts against the aforementioned energized piece 1413, and conduction is achieved between the energized piece 1413 and the conductive post 1412 of the first conductive module 141. When the clean water tank 131 is installed on the floor brush base 12, the power supply device and the first conductive module 141 are connected through the conductive needle 1422. The structure is simple, and the position of the conductive needle 1422 on the floor brush base 12 matches the first conductive module 141. The user only needs to install the clean water tank 131 on the floor brush base 12, without any other operation, to make the detection element 31 connected to the power supply device, which is convenient to operate.

[0106] refer to Figure 4 , Figure 10 and Figure 11 According to some embodiments of the present invention, the conductive needle 1422 is movable along the thickness direction of the floor brush housing 10. The second conductive module 142 may also include an elastic reset member 1423. The elastic reset member 1423 is disposed in the assembly hole and sleeved on the outside of the conductive needle 1422. The two ends of the elastic reset member 1423 are respectively connected to the package body 1421 and the conductive needle 1422.

[0107] For example, the outer wall of the conductive needle 1422 may have a circumferentially protruding ring, and the two ends of the elastic reset member 1423 abut against the bottom wall of the convex ring and the mounting hole, respectively. The elastic reset member 1423 applies a reset force to the conductive needle 1422 through the convex ring.

[0108] Thus, when the clean water tank 131 is installed on the floor brush base 12, the energized piece 1413 presses against the conductive pin 1422, causing the conductive pin 1422 to move towards the floor brush base 12. The elastic reset member 1423 then retracts, preventing damage to the conductive pin 1422. Furthermore, the elastic reset member 1423 applies a force to the conductive pin 1422 towards the first conductive module 141, making the electrical connection between the conductive pin 1422 and the first conductive module 141 more reliable.

[0109] Optionally, the elastic reset element 1423 may include, but is not limited to, springs, rubber sleeves, and silicone sleeves, which helps to save equipment costs.

[0110] refer to Figure 10 and Figure 11 According to some embodiments of the present invention, the package 1421 may include a first package 1421a and a second package 1421b, which are connected to each other. For example, the first package 1421a and the second package 1421b may be fastened together by a snap-fit, or the first package 1421a and the second package 1421b may be fixed together by screws or other fasteners.

[0111] The mounting hole penetrates the first package 1421a and the second package 1421b. A portion of the conductive pin 1422 passes through the first package 1421a and another portion passes through the second package 1421b. For example, there may be an expansion space between the first package 1421a and the second package 1421b. The protruding ring on the conductive pin 1422 is located in the expansion space, and the outer diameter of the protruding ring exceeds the diameter of the mounting hole.

[0112] The second connecting end 1422b of the conductive pin 1422 passes through the lower end of the through hole 1131d of the second package 1421b and is electrically connected to the power supply device via a conductive wire. The first connecting end 1422a of the conductive pin 1422 passes through the upper end of the through hole 1131d of the first package 1421a and abuts against the energized piece 1413. Thus, when components of the second conductive module 142 need maintenance or replacement, only the package 1421 needs to be removed, and the first package 1421a and the second package 1421b need to be opened for maintenance or replacement. This eliminates the need to replace the entire second conductive module 142, saving maintenance costs and improving user satisfaction.

[0113] Understandably, the package 1421 is mounted on the floor brush base 12. It may be formed with a latch on at least one of the first package 1421a or the second package 1421b. The floor brush base 12 has a slot. The package 1421 is detachably mounted on the floor brush base 12 by the cooperation between the latch and the slot.

[0114] According to some embodiments of this utility model, the first package 1421a and the second package 1421b are sealed together. For example, a sealing ring may be provided at the connection between the first package 1421a and the second package 1421b. Alternatively, the connection between the first package 1421a and the second package 1421b may also be coated with sealant.

[0115] In this way, moisture and dirt can be prevented from entering the package 1421 from the connection between the first package 1421a and the second package 1421b, thus preventing corrosion of the conductive pin 1422.

[0116] The conductive pin 1422 is sealed to the mounting hole. For example, a sealing sleeve can be provided at the gap between the conductive pin 1422 and the mounting hole. The sleeve is fitted onto the inner wall of the mounting hole, does not affect the extension and retraction of the conductive pin 1422, and simultaneously prevents dirt from entering the package 1421. This ensures that the second conductive module 142 is in a relatively sealed environment, preventing moisture or dirt from entering the package 1421, thus extending the service life of the second conductive module 142.

[0117] Secondly, embodiments of this application also provide a cleaning device, which may include a main unit and the aforementioned floor brush device 100. The main unit may include a body and a power supply device disposed on the body, and the electrode detection device of the floor brush device 100 is connected to the power supply device.

[0119] In addition, in other alternative embodiments, the host may also be equipped with a wastewater tank. The floor brush device 100 cleans the ground or other surfaces to be cleaned. The wastewater tank can collect wastewater on the ground when the floor brush device 100 is cleaning. When the wastewater tank is full, it can be removed from the host and transferred to the cleaning base station for wastewater discharge and cleaning operations.

[0120] The cleaning equipment of this utility model, by using the aforementioned floor brush device 100, allows for a more accurate assessment of the moisture content of the roller brush mechanism 20 during the drying process, which helps users accurately grasp the degree of dryness of the roller brush mechanism 20 and improves user satisfaction.
