DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] Example 1

[0031] An embodiment of the present utility model provides a floor cleaning device comprising a charging transmitter assembly 1 and a cleaning main unit 2. The charging transmitter assembly 1 comprises a plurality of transmitter units 11 disposed on a floor 3, wherein the combined transmission coverage of the plurality of transmitter units 11 at least completely covers the area to be cleaned. The cleaning main unit 2 is internally provided with a charging receiver assembly 21. The cleaning main unit 2 is configured to be movable on the floor 3 so as to trigger the corresponding transmitter unit 11 when passing by it, thereby establishing a wireless power transmission relationship between the charging receiver assembly 21 and the triggered transmitter unit 11.

[0032] Specifically, the technical problem to be solved by the present invention is as described in the background technology section above, namely, to solve the problem that the battery life and ease of use of current floor cleaning devices (floor cleaning devices include various specific types such as sweeping robots, mopping robots and floor washing robots) cannot be taken into account at the same time.

[0033] Current floor cleaning devices are mainly divided into two categories based on their battery life: the first category uses a power cord to connect to the power grid, and maintains power to the municipal power grid through the power cord during operation; the second category carries a rechargeable battery, is powered by the battery during operation, works wirelessly, and is recharged during breaks in operation. The power supply structure and battery life of the first type of floor cleaning device are relatively simple, and the power cord is directly connected to the power grid; its disadvantage is that the power cord will be continuously pulled while the floor cleaning device is moving and cleaning, which can easily cause entanglement and the power cord plug to fall off, making it inconvenient to use. The second type of floor cleaning device is battery-powered and can be used wirelessly, avoiding the problem of power cord pulling and being easy to use; its disadvantage is that it requires additional batteries and charging compartments, which are more complex in structure and more expensive, and the battery will increase the weight of the cleaning device, making it inconvenient to use in certain scenarios that require manual transfer; in addition, the battery needs to be charged from time to time, affecting overall work efficiency, and as the battery performance decays, the single-time battery life will decrease, further affecting work efficiency.

[0034] This utility model aims to address the aforementioned technical deficiencies of existing floor cleaning devices. The main technical concepts of this utility model are: first, to improve ease of use, the power cord is removed and wireless power is adopted; second, to improve work efficiency, the charging process is shortened or preferably eliminated, while ensuring the device's battery life. Therefore, the main inventive concept of the technical solution proposed by this utility model is to enable the floor cleaning device to be charged during operation, that is, to be used while charging.

[0035] Based on the above technical concepts, the floor cleaning device of the present invention mainly comprises two parts in terms of structure: a cleaning main unit 2 and a charging transmitter assembly 1. The multiple transmitting units 11 of the charging transmitter assembly 1 are laid on the ground 3, and the overall transmission coverage area at least completely covers the ground 3 in the area to be cleaned. The cleaning main unit 2 is provided with a charging receiver assembly 21. As the cleaning main unit 2 moves along the ground 3, it will pass by different transmitting units 11. When it corresponds to or approaches a corresponding transmitting unit 11, it can trigger the transmitting unit 11, so that the charging receiver assembly 21 establishes a wireless transmission relationship with the triggered transmitting unit 11, thereby performing wireless charging. The floor cleaning device of the present invention utilizes a wireless charging transmitting component laid on the ground and a receiving component provided on the cleaning main unit. This allows the cleaning main unit to be used while charging during operation. While maintaining the advantages of battery power and wireless use, it optimizes the dedicated charging process, thereby achieving both ease of use and work efficiency. In addition, the battery life of the device is no longer dependent on the capacity of the battery, allowing the use of small batteries, reducing the weight of the device and reducing the cost of use.

[0036] Furthermore, the charging transmitter assembly 1 also includes a plurality of floor tiles 12 laid on the ground 3 , and each floor tile 12 is embedded with a transmitter unit 11 .

[0037] Specifically, as shown in the accompanying drawings Figures 1 to 4 As shown, the charging transmitter assembly 1 also includes floor tiles 12 for use with the transmitter unit 11. The floor tiles 12 are used to mount the transmitter unit 11, allowing the transmitter unit 11 to be densely laid along with the floor tiles 12 on the floor 3 in the usage scenario. The transmitter unit 11 is mounted on the floor tiles 12 by providing mounting grooves on the bottom surface of the floor tiles 12. The various components of the transmitter unit 11 are embedded in the mounting grooves and fixed therein by adhesive. After the floor tiles 12 are laid on the floor 3, the transmitter unit 11 is hidden underneath, without affecting the flatness of the floor 3 in the scene.

[0038] Furthermore, the cleaning host 2 includes a battery electrically connected to a charging receiving assembly 21, which can receive the electrical energy output by the transmitting unit 11 through the charging receiving assembly 21. Furthermore, the cleaning components of the cleaning host 2 (e.g., the roller brush mechanism, mopping mechanism, vacuum mechanism, and other cleaning components) can be connected to the battery in either series or parallel configurations. In a series configuration, electrical energy first enters the battery and is then delivered to the cleaning components. In a series-parallel configuration, the input terminals of the cleaning components are connected to both the battery and the charging receiving assembly 21, allowing power to be drawn from either the battery or the charging receiving assembly 21 as needed. In this embodiment, the cleaning components are preferably connected to the battery in series or parallel configurations.

[0039] Example 2

[0040] An embodiment of the present utility model provides a floor cleaning device comprising a charging transmitter assembly 1 and a cleaning main unit 2. The charging transmitter assembly 1 comprises a plurality of transmitter units 11 disposed on a floor 3, wherein the combined transmission coverage of the plurality of transmitter units 11 at least completely covers the area to be cleaned.

The main technical concepts of this utility model are: first, to improve ease of use, the power cord is removed and wireless power is adopted; second, to improve work efficiency, the charging process is shortened or preferably eliminated, while ensuring the device's battery life. Therefore, the main inventive concept of the technical solution proposed by this utility model is to enable the floor cleaning device to be charged during operation, that is, to be used while charging.

[0044] Based on the above technical concepts, the floor cleaning device of the present invention mainly comprises two parts in terms of structure: a cleaning main unit 2 and a charging transmitter assembly 1. The multiple transmitting units 11 of the charging transmitter assembly 1 are laid on the ground 3, and the overall transmission coverage area at least completely covers the ground 3 in the area to be cleaned. The cleaning main unit 2 is provided with a charging receiver assembly 21. As the cleaning main unit 2 moves along the ground 3, it will pass by different transmitting units 11.

The floor cleaning device of the present invention utilizes a wireless charging transmitting component laid on the ground and a receiving component provided on the cleaning main unit. This allows the cleaning main unit to be used while charging during operation. While maintaining the advantages of battery power and wireless use, it optimizes the dedicated charging process, thereby achieving both ease of use and work efficiency. In addition, the battery life of the device is no longer dependent on the capacity of the battery, allowing the use of small batteries, reducing the weight of the device and reducing the cost of use.

[0045] Furthermore, the charging transmitter assembly 1 also includes a plurality of floor tiles 12 laid on the ground 3 , and each floor tile 12 is embedded with a transmitter unit 11 .

[0046] Specifically, as shown in the accompanying drawings Figures 1 to 4 As shown, the charging transmitter assembly 1 also includes floor tiles 12 for use with the transmitter unit 11. The floor tiles 12 are used to mount the transmitter unit 11, allowing the transmitter unit 11 to be densely laid along with the floor tiles 12 on the floor 3 in the usage scenario. The transmitter unit 11 is mounted on the floor tiles 12 by providing mounting grooves on the bottom surface of the floor tiles 12. The various components of the transmitter unit 11 are embedded in the mounting grooves and fixed therein by adhesive. After the floor tiles 12 are laid on the floor 3, the transmitter unit 11 is hidden underneath, without affecting the flatness of the floor 3 in the scene.

[0047] Furthermore, the cleaning host 2 includes a battery electrically connected to a charging receiving assembly 21, which can receive the electrical energy output by the transmitting unit 11 through the charging receiving assembly 21. Furthermore, the cleaning components of the cleaning host 2 (e.g., the roller brush mechanism, mopping mechanism, vacuum mechanism, and other cleaning components) can be connected to the battery in either series or parallel configurations. In a series configuration, electrical energy first enters the battery and is then delivered to the cleaning components. In a series-parallel configuration, the input terminals of the cleaning components are connected to both the battery and the charging receiving assembly 21, allowing power to be drawn from either the battery or the charging receiving assembly 21 as needed. In this embodiment, the cleaning components are preferably connected to the battery in series or parallel configurations.

[0048] Furthermore, the transmitting unit 11 includes a plurality of transmitting coils 111 and at least one induction switch 112 . The induction switch 112 is configured to sense the cleaning host 2 so as to turn on or off the transmitting coil 111 when the cleaning host 2 enters or exits the induction range.

[0049] Specifically, as shown in the accompanying drawings Figure 3 and Figure 4 As shown, the transmitting unit 11 includes a transmitting coil 111 for establishing a wireless transmission relationship with the charging receiving component 21 of the cleaning host 2, and a sensing switch 112 for controlling the start and stop of the transmitting coil 111. The sensing switch 112 can sense the cleaning host 2. After the cleaning host 2 enters the sensing range, the sensing switch 112 is triggered to turn on the corresponding transmitting coil 111, and then the battery of the cleaning host 2 is charged through the transmitting coil 111 and the charging receiving component 21, or the cleaning component of the cleaning host 2 is directly powered.

[0050] Preferably, the induction switch 112 is configured as a Hall switch, which can sense magnetic fields and thereby perform induction detection on the cleaning host. Accordingly, the cleaning host 2 is provided with at least one magnetic induction member 22, which is configured to trigger the induction switch 112 through a magnetic field. Since the induction switch 112 is configured as a Hall switch, when the cleaning host 2 approaches the corresponding transmitting unit 11, the Hall switch of the transmitting unit 11 can sense the magnetic field of the magnetic induction member 22, thereby determining the relative position of the cleaning host 2, and activating the transmitting coil 111 when the cleaning host 2 passes the corresponding transmitting unit 11.

[0051] Optionally, the transmitting unit 11 includes a plurality of transmitting coils 111 and an inductive switch 112 , and the inductive switch 112 is disposed at the center of the coverage area of ​​the plurality of transmitting coils 111 .

[0052] Specifically, as shown in the accompanying drawings Figure 3 and Figure 4 As shown, the transmitting unit 11 includes a plurality of transmitting coils 111 distributed in an array and an induction switch 112 arranged at the center of the distribution array. The purpose of such distribution is to place the induction switch 112 at the center of the transmitting unit 11. In this way, when the induction switch 112 senses the cleaning host 2, it can be ensured that at least a part of the cleaning host 2 has entered the coverage range of the transmitting coil 111, thereby ensuring that the cleaning host 2 can be effectively powered.

[0053] In addition, based on the aforementioned floor tiles 12, a transmitting unit 11 is provided in each floor tile 12, and the induction switch 112 at the center of the transmitting unit 11 is located at the center of the floor tile 12. The induction switch 112 is constructed to be able to simultaneously turn on or off each transmitting coil 111 in the transmitting unit 11 to achieve unified control. In this way, the control structure can be simplified as much as possible while meeting the usage requirements, avoiding the control structure being too complicated and requiring a large number of electrical components, which is inconvenient to install in the floor tile 12.

[0060] Furthermore, the charging transmitter assembly 1 also includes a plurality of floor tiles 12 laid on the ground 3 , and each floor tile 12 is embedded with a transmitter unit 11 .

[0061] Specifically, as shown in the accompanying drawings Figures 1 to 4 As shown, the charging transmitter assembly 1 also includes floor tiles 12 for use with the transmitter unit 11. The floor tiles 12 are used to mount the transmitter unit 11, allowing the transmitter unit 11 to be densely laid along with the floor tiles 12 on the floor 3 in the usage scenario. The transmitter unit 11 is mounted on the floor tiles 12 by providing mounting grooves on the bottom surface of the floor tiles 12. The various components of the transmitter unit 11 are embedded in the mounting grooves and fixed therein by adhesive. After the floor tiles 12 are laid on the floor 3, the transmitter unit 11 is hidden underneath, without affecting the flatness of the floor 3 in the scene.

[0062] Furthermore, the cleaning host 2 includes a battery electrically connected to a charging receiving assembly 21, which can receive the electrical energy output by the transmitting unit 11 through the charging receiving assembly 21. Furthermore, the cleaning components of the cleaning host 2 (e.g., the roller brush mechanism, mopping mechanism, vacuum mechanism, and other cleaning components) can be connected to the battery in either series or parallel configurations. In a series configuration, electrical energy first enters the battery and is then delivered to the cleaning components. In a series-parallel configuration, the input terminals of the cleaning components are connected to both the battery and the charging receiving assembly 21, allowing power to be drawn from either the battery or the charging receiving assembly 21 as needed. In this embodiment, the cleaning components are preferably connected to the battery in series or parallel configurations.

[0063] Furthermore, the transmitting unit 11 includes a plurality of transmitting coils 111 and at least one induction switch 112 . The induction switch 112 is configured to sense the cleaning host 2 so as to turn on or off the transmitting coil 111 when the cleaning host 2 enters or exits the induction range.

[0064] Specifically, as shown in the accompanying drawings Figure 3 and Figure 4 As shown, the transmitting unit 11 includes a transmitting coil 111 for establishing a wireless transmission relationship with the charging receiving component 21 of the cleaning host 2, and a sensing switch 112 for controlling the start and stop of the transmitting coil 111. The sensing switch 112 can sense the cleaning host 2. After the cleaning host 2 enters the sensing range, the sensing switch 112 is triggered to turn on the corresponding transmitting coil 111, and then the battery of the cleaning host 2 is charged through the transmitting coil 111 and the charging receiving component 21, or the cleaning component of the cleaning host 2 is directly powered.

[0065] Preferably, the induction switch 112 is configured as a Hall switch, which can sense magnetic fields and thereby perform induction detection on the cleaning host. Accordingly, the cleaning host 2 is provided with at least one magnetic induction member 22, which is configured to trigger the induction switch 112 through a magnetic field.

[0066] Optionally, the transmitting unit 11 includes a plurality of transmitting coils 111 and an inductive switch 112 , and the inductive switch 112 is disposed at the center of the coverage area of ​​the plurality of transmitting coils 111 .

[0067] Specifically, as shown in the accompanying drawings Figure 3 and Figure 4 As shown, the transmitting unit 11 includes a plurality of transmitting coils 111 distributed in an array and an induction switch 112 arranged at the center of the distribution array. The purpose of such distribution is to place the induction switch 112 at the center of the transmitting unit 11. In this way, when the induction switch 112 senses the cleaning host 2, it can be ensured that at least a part of the cleaning host 2 has entered the coverage range of the transmitting coil 111, thereby ensuring that the cleaning host 2 can be effectively powered.

[0068] In addition, based on the aforementioned floor tiles 12, a transmitting unit 11 is provided in each floor tile 12, and the induction switch 112 at the center of the transmitting unit 11 is located at the center of the floor tile 12. The induction switch 112 is constructed to be able to simultaneously turn on or off each transmitting coil 111 in the transmitting unit 11 to achieve unified control. In this way, the control structure can be simplified as much as possible while meeting the usage requirements, avoiding the control structure being too complicated and requiring a large number of electrical components, which is inconvenient to install in the floor tile 12.

[0069] Furthermore, the induction switch 112 is constructed such that its induction range does not exceed the overall coverage range of the transmitting coils 111 of the transmitting unit 11 .

[0070] Specifically, as shown in the accompanying drawings Figure 3 and Figure 4 As shown, the multiple transmitting coils 111 in the transmitting unit 11 correspond to a coverage range as a whole. The coverage range preferably refers to the effective wireless transmission coverage range of the transmitting coil 111, rather than just the range corresponding to the location of the transmitting coil 111 itself. The sensing range of the induction switch 112 is preferably constructed so as not to exceed the overall coverage range of the transmitting coil 111. The purpose is to save energy. Because if the sensing range of the induction switch 112 exceeds the overall coverage range of the transmitting coil 111, it is possible that the induction switch 112 senses the cleaning host 2 and turns on the transmitting coil 111, but the cleaning host 2 is not within the effective wireless transmission coverage range of the transmitting coil 111 and cannot be charged, resulting in energy waste.

[0071] Furthermore, the distance between the induction range boundaries of the induction switches 112 of two adjacent transmitting units 11 is smaller than the width of the magnetic field of the magnetic induction element 22 .

[0072] Specifically, the distance between the sensing range boundaries of the induction switches 112 of two adjacent transmitting units 11 is limited primarily to ensure that, at any given moment, the cleaning host 2 can be sensed by at least one transmitting unit 11, thereby activating its transmitting coil 111 and powering the cleaning host 2. Further preferably, the coverage areas of the transmitting coils 111 of two adjacent transmitting units 11 are conveniently connected or partially overlapped, further ensuring that the cleaning host 2 can be powered at any given moment and at any location on the ground 3.

[0073] Example 4

[0074] An embodiment of the present utility model provides a floor cleaning device comprising a charging transmitter assembly 1 and a cleaning main unit 2. The charging transmitter assembly 1 comprises a plurality of transmitter units 11 disposed on a floor 3, wherein the combined transmission coverage of the plurality of transmitter units 11 at least completely covers the area to be cleaned. The cleaning main unit 2 is internally provided with a charging receiver assembly 21. The cleaning main unit 2 is configured to be movable on the floor 3 so as to trigger the corresponding transmitter unit 11 when passing by it, thereby establishing a wireless power transmission relationship between the charging receiver assembly 21 and the triggered transmitter unit 11.

[0076] Current floor cleaning devices are mainly divided into two categories based on their battery life: the first category uses a power cord to connect to the power grid, and maintains power to the municipal power grid through the power cord during operation; the second category carries a rechargeable battery, is powered by the battery during operation, works wirelessly, and is recharged during breaks in operation. The power supply structure and battery life of the first type of floor cleaning device are relatively simple, and the power cord is directly connected to the power grid; its disadvantage is that the power cord will be continuously pulled while the floor cleaning device is moving and cleaning, which can easily cause entanglement and the power cord plug to fall off, making it inconvenient to use. The second type of floor cleaning device is battery-powered and can be used wirelessly, avoiding the problem of power cord pulling and being easy to use; its disadvantage is that it requires additional batteries and charging compartments, which are more complex in structure and more expensive, and the battery will increase the weight of the cleaning device, making it inconvenient to use in certain scenarios that require manual transfer; in addition, the battery needs to be charged from time to time, affecting overall work efficiency, and as the battery performance decays, the single-time battery life will decrease, further affecting work efficiency.

[0077] This utility model aims to address the aforementioned technical deficiencies of existing floor cleaning devices. The main technical concepts of this utility model are: first, to improve ease of use, the power cord is removed and wireless power is adopted; second, to improve work efficiency, the charging process is shortened or preferably eliminated, while ensuring the device's battery life. Therefore, the main inventive concept of the technical solution proposed by this utility model is to enable the floor cleaning device to be charged during operation, that is, to be used while charging.

[0078] Based on the above technical concepts, the floor cleaning device of the present invention mainly comprises two parts in terms of structure: a cleaning main unit 2 and a charging transmitter assembly 1. The multiple transmitting units 11 of the charging transmitter assembly 1 are laid on the ground 3, and the overall transmission coverage area at least completely covers the ground 3 in the area to be cleaned. The cleaning main unit 2 is provided with a charging receiver assembly 21. As the cleaning main unit 2 moves along the ground 3, it will pass by different transmitting units 11. When it corresponds to or approaches a corresponding transmitting unit 11, it can trigger the transmitting unit 11, so that the charging receiver assembly 21 establishes a wireless transmission relationship with the triggered transmitting unit 11, thereby performing wireless charging. The floor cleaning device of the present invention utilizes a wireless charging transmitting component laid on the ground and a receiving component provided on the cleaning main unit. This allows the cleaning main unit to be used while charging during operation. While maintaining the advantages of battery power and wireless use, it optimizes the dedicated charging process, thereby achieving both ease of use and work efficiency. In addition, the battery life of the device is no longer dependent on the capacity of the battery, allowing the use of small batteries, reducing the weight of the device and reducing the cost of use.

[0079] Furthermore, the charging transmitter assembly 1 also includes a plurality of floor tiles 12 laid on the ground 3 , and each floor tile 12 is embedded with a transmitter unit 11 .

[0080] Specifically, as shown in the accompanying drawings Figures 1 to 4 As shown, the charging transmitter assembly 1 also includes floor tiles 12 for use with the transmitter unit 11. The floor tiles 12 are used to mount the transmitter unit 11, allowing the transmitter unit 11 to be densely laid along with the floor tiles 12 on the floor 3 in the usage scenario. The transmitter unit 11 is mounted on the floor tiles 12 by providing mounting grooves on the bottom surface of the floor tiles 12. The various components of the transmitter unit 11 are embedded in the mounting grooves and fixed therein by adhesive. After the floor tiles 12 are laid on the floor 3, the transmitter unit 11 is hidden underneath, without affecting the flatness of the floor 3 in the scene.

[0081] Furthermore, the cleaning host 2 includes a battery electrically connected to a charging receiving assembly 21, which can receive the electrical energy output by the transmitting unit 11 through the charging receiving assembly 21. Furthermore, the cleaning components of the cleaning host 2 (e.g., the roller brush mechanism, mopping mechanism, vacuum mechanism, and other cleaning components) can be connected to the battery in either series or parallel configurations. In a series configuration, electrical energy first enters the battery and is then delivered to the cleaning components. In a series-parallel configuration, the input terminals of the cleaning components are connected to both the battery and the charging receiving assembly 21, allowing power to be drawn from either the battery or the charging receiving assembly 21 as needed. In this embodiment, the cleaning components are preferably connected to the battery in series or parallel configurations.

[0082] Furthermore, the transmitting unit 11 includes a plurality of transmitting coils 111 and at least one induction switch 112 . The induction switch 112 is configured to sense the cleaning host 2 so as to turn on or off the transmitting coil 111 when the cleaning host 2 enters or exits the induction range.

[0083] Specifically, as shown in the accompanying drawings Figure 3 and Figure 4 As shown, the transmitting unit 11 includes a transmitting coil 111 for establishing a wireless transmission relationship with the charging receiving component 21 of the cleaning host 2, and a sensing switch 112 for controlling the start and stop of the transmitting coil 111. The sensing switch 112 can sense the cleaning host 2. After the cleaning host 2 enters the sensing range, the sensing switch 112 is triggered to turn on the corresponding transmitting coil 111, and then the battery of the cleaning host 2 is charged through the transmitting coil 111 and the charging receiving component 21, or the cleaning component of the cleaning host 2 is directly powered.

[0084] Preferably, the induction switch 112 is configured as a Hall switch, which can sense magnetic fields and thereby perform induction detection on the cleaning host. Accordingly, the cleaning host 2 is provided with at least one magnetic induction member 22, which is configured to trigger the induction switch 112 through a magnetic field. Since the induction switch 112 is configured as a Hall switch, when the cleaning host 2 approaches the corresponding transmitting unit 11, the Hall switch of the transmitting unit 11 can sense the magnetic field of the magnetic induction member 22, thereby determining the relative position of the cleaning host 2, and activating the transmitting coil 111 when the cleaning host 2 passes the corresponding transmitting unit 11.

[0085] Optionally, the transmitting unit 11 includes a plurality of transmitting coils 111 and an inductive switch 112 , and the inductive switch 112 is disposed at the center of the coverage area of ​​the plurality of transmitting coils 111 .

[0086] Specifically, as shown in the accompanying drawings Figure 3 and Figure 4 As shown, the transmitting unit 11 includes a plurality of transmitting coils 111 distributed in an array and an induction switch 112 arranged at the center of the distribution array. The purpose of such distribution is to place the induction switch 112 at the center of the transmitting unit 11. In this way, when the induction switch 112 senses the cleaning host 2, it can be ensured that at least a part of the cleaning host 2 has entered the coverage range of the transmitting coil 111, thereby ensuring that the cleaning host 2 can be effectively powered.

[0087] In addition, based on the aforementioned floor tiles 12, a transmitting unit 11 is provided in each floor tile 12, and the induction switch 112 at the center of the transmitting unit 11 is located at the center of the floor tile 12. The induction switch 112 is constructed to be able to simultaneously turn on or off each transmitting coil 111 in the transmitting unit 11 to achieve unified control. In this way, the control structure can be simplified as much as possible while meeting the usage requirements, avoiding the control structure being too complicated and requiring a large number of electrical components, which is inconvenient to install in the floor tile 12.

[0088] Furthermore, as shown in the accompanying drawings Figure 5 As shown, the control process of the floor cleaning device of the present invention is as follows: when the floor cleaning device is placed on the floor 3 in the corresponding scene, the transmitting coil 111 of the triggered transmitting unit 11 near the cleaning host 2 is activated to charge the cleaning host 2. When the cleaning host 2 moves over a workpiece, if the center of the distribution range of the transmitting coil 111 (i.e., the location of the induction switch 112) corresponds to the cleaning host 2, the induction switch 112 is triggered and the transmitting coil 111 it controls is activated. If the center of the distribution range of the transmitting coil 111 corresponds to the cleaning host 2, the corresponding transmitting coil 111 is controlled to be turned off.

[0089] Furthermore, the induction switch 112 is constructed such that its induction range does not exceed the overall coverage range of the transmitting coils 111 of the transmitting unit 11 .

[0090] Specifically, as shown in the accompanying drawings Figure 3 and Figure 4 As shown, the multiple transmitting coils 111 in the transmitting unit 11 correspond to a coverage range as a whole. The coverage range preferably refers to the effective wireless transmission coverage range of the transmitting coil 111, rather than just the range corresponding to the location of the transmitting coil 111 itself. The sensing range of the induction switch 112 is preferably constructed so as not to exceed the overall coverage range of the transmitting coil 111. The purpose is to save energy. Because if the sensing range of the induction switch 112 exceeds the overall coverage range of the transmitting coil 111, it is possible that the induction switch 112 senses the cleaning host 2 and turns on the transmitting coil 111, but the cleaning host 2 is not within the effective wireless transmission coverage range of the transmitting coil 111 and cannot be charged, resulting in energy waste.

[0091] Furthermore, the distance between the induction range boundaries of the induction switches 112 of two adjacent transmitting units 11 is smaller than the width of the magnetic field of the magnetic induction element 22 .

[0092] Specifically, the distance between the sensing range boundaries of the induction switches 112 of two adjacent transmitting units 11 is limited primarily to ensure that, at any given moment, the cleaning host 2 can be sensed by at least one transmitting unit 11, thereby activating its transmitting coil 111 and powering the cleaning host 2. Further preferably, the coverage areas of the transmitting coils 111 of two adjacent transmitting units 11 are conveniently connected or partially overlapped, further ensuring that the cleaning host 2 can be powered at any given moment and at any location on the ground 3.

[0093] Furthermore, the charging receiving component 21 includes a plurality of receiving coils 211 , and the plurality of receiving coils 211 are evenly arranged at the bottom of the cleaning host 2 .

[0094] Specifically, as shown in the accompanying drawings Figure 3 and Figure 4 As shown, the charging receiving component 21 is arranged in the floor brush part 23 of the cleaning host 2 (in addition to the floor brush part 23, the cleaning host 2 also has a body 24. In this embodiment, the body 24 is for the user to grasp and operate the floor cleaning device). Specifically, it is embedded in the bottom of the bottom shell 231 of the floor brush part 23, and the overall distribution range of multiple receiving coils 211 covers the entire bottom of the floor brush part 23.
