Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a floor brush and cleaning equipment. Background Technology

[0002] Taking vacuum cleaners as an example, a cleaning device uses vacuum suction to pick up debris from a surface to be cleaned. When cleaning a specific area of ​​the surface, the user typically pushes the vacuum cleaner forward, causing the brush to move forward on the surface, and then pulls it back, causing the brush to move backward. This repeated pushing and pulling motion is used to clean the target area before repositioning the vacuum cleaner to clean the next area. However, the user is often unaware of whether the target area has been truly cleaned, meaning there is a possibility that some areas may not have been properly cleaned.

[0003] Furthermore, since users are not sure whether the target area has been truly cleaned, they often increase the number of push and pull cycles before repositioning the vacuum cleaner to ensure cleaning effectiveness, resulting in lower cleaning efficiency. Utility Model Content

[0005] A first aspect of this application provides a floor brush, the floor brush comprising:

[0021] Optionally, at least one of the first light-emitting device and the second light-emitting device is mounted on the outer wall of the brush cap facing away from the receiving cavity; or,

[0022] The brush cap is provided with a light-emitting hole, and at least one of the first light-emitting device and the second light-emitting device is located in the receiving cavity and installed on the inner wall of the brush cap facing the receiving cavity.

[0030] A second aspect of this application provides a cleaning device, the cleaning device including the floor brush described in any embodiment of the first aspect.

[0031] In this embodiment, by providing light-emitting devices (a first light-emitting device and a second light-emitting device) on the front and rear sides of the floor brush body, the cleaning equipment can meet the lighting needs of different cleaning directions. Furthermore, these two light-emitting devices provide the hardware foundation for implementing multiple control modes, improving the flexibility of the cleaning equipment in different usage scenarios. The first light-emitting device illuminates the cleaned area on the front side of the floor brush body, helping the user check whether this area is clean. The second light-emitting device illuminates the cleaned area on the rear side of the floor brush body, helping the user check whether this area is clean. If the user finds that a cleaned area is not clean, it can be cleaned again promptly, improving cleaning effectiveness and user experience.

[0032] The first and second light-emitting devices are used to illuminate the cleaned areas. This means that there's no need to turn on the corresponding light-emitting device for uncleaned areas. For example, during the initial forward push of the vacuum cleaner, the first light-emitting device can be turned off, and the second light-emitting device can be turned on, illuminating only the cleaned areas at the rear. This reduces unnecessary lighting and energy consumption.

[0033] During the cleaning process, while pushing the vacuum cleaner forward, activate the second light device to illuminate the rear of the floor brush body. If the cleaned area at the rear is found to be clean, the vacuum cleaner can continue pushing forward without pulling it back. If, while continuing to push forward, the cleaned area at the rear is not yet cleaned, the vacuum cleaner can be pulled back and the cleaning process repeated until it is clean, thus reducing unnecessary repetitive cleaning actions. While pulling the vacuum cleaner back, use the first light device to illuminate the front of the floor brush body. If the cleaned area at the front is found to be cleaned, the vacuum cleaner can be repositioned; if the cleaned area at the front is still not cleaned, it can be pushed forward again and the cleaning action for the same area can be repeated. Therefore, using the first and second light devices can also effectively improve cleaning efficiency. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] The cleaning equipment described in this application includes, but is not limited to, vacuum cleaners, floor scrubbers, and mite removers. For ease of description, a vacuum cleaner will be used as an example.

[0047] Figure 1 A schematic diagram of a vacuum cleaner is shown as an example. The vacuum cleaner includes a floor brush 100, a body 200, and a main unit 300. The floor brush 100 can move back and forth on the surface to be cleaned. The body 200 connects the floor brush 100 and the main unit 300, and forms a channel through which airflow carrying debris is sucked into the main unit 300 via a suction port on the floor brush 100. The body 200 can be rod-shaped or tubular, and has a channel inside. Debris includes dust, dander, paper scraps, hair, rice grains, fruit peels, etc. The surface to be cleaned includes, but is not limited to, floors, walls, and carpet surfaces. For ease of description, a floor is used as an example below.

[0048] The main unit 300 includes a suction device 310 and a separation device 320. The suction device 310 includes a motor and an impeller. The motor drives the impeller to rotate to form a suction flow. The separation device 320 is used to separate the waste from the airflow. The separated waste can be temporarily stored in the separation device 320, while the airflow can be discharged through the exhaust port on the suction device 310.

[0049] Figure 2 An example is shown applying to Figure 1 A floor brush 100 for a vacuum cleaner. The floor brush 100 includes a floor brush body 120, a first light-emitting device 140, and a second light-emitting device 150. The floor brush body 120 includes a receiving cavity for accommodating cleaning components. The first light-emitting device 140 and the second light-emitting device 150 are respectively installed on the front and rear sides of the floor brush body 120. The lateral direction of the floor brush body 120 is perpendicular to the direction in which the floor brush body 120 travels back and forth on the surface to be cleaned. The first light-emitting device 140 is used to illuminate the cleaned area located on the front side of the floor brush body 120, and the second light-emitting device 150 is used to illuminate the cleaned area located on the rear side of the floor brush body 120.

[0050] The cleaning component is rotatably mounted on the floor brush body 120. The aforementioned suction port is located on the floor brush body 120 and communicates with the receiving cavity. Part of the cleaning component is located inside the receiving cavity, and the other part passes through the opening of the receiving cavity and contacts the ground. As the floor brush body 120 moves back and forth, it drives the cleaning component to scrape the ground. The debris on the ground is brushed up and flows through the suction port and the channel 200 of the machine body into the separation device 320, thus achieving the cleaning purpose.

[0051] By installing light-emitting devices (referring to the first light-emitting device 140 and the second light-emitting device 150) on the front and rear sides of the floor brush body 120 respectively, the cleaning equipment can meet the lighting needs of different cleaning directions. Moreover, these two light-emitting devices provide the hardware foundation for the realization of multiple control modes, which can improve the flexibility of the cleaning equipment in different usage scenarios.

[0052] The first light-emitting device 140 illuminates the cleaned area on the front of the brush body 120, helping the user check whether the cleaned area on the front of the brush body 120 is clean. The second light-emitting device 150 illuminates the cleaned area on the rear of the brush body 120, helping the user check whether the cleaned area on the rear of the brush body 120 is clean. If the user finds that the cleaned area is not clean, they can clean it again in time, improving the cleaning effect and user experience.

[0053] The first light-emitting device 140 and the second light-emitting device 150 are used to illuminate the cleaned areas. That is, there is no need to turn on the corresponding light-emitting device for uncleaned areas. For example, during the initial forward push of the vacuum cleaner, the first light-emitting device 140 can be turned off and the second light-emitting device 150 can be turned on to illuminate only the cleaned areas at the rear. In this way, unnecessary illumination time can be reduced, thus reducing energy consumption.

[0054] During the cleaning process, while pushing the vacuum cleaner forward, the second light-emitting device 150 illuminates the rear of the floor brush body 120. If the cleaned area at the rear is found to be clean, the vacuum cleaner does not need to be pulled back and can continue to be pushed forward. If, during the continued forward pushing, the cleaned area at the rear is not cleaned, the vacuum cleaner can be pulled back and the cleaning can be repeated until it is clean, thus reducing unnecessary repetitive cleaning actions. During the pulling back of the vacuum cleaner, the first light-emitting device 140 illuminates the front of the floor brush body 120. If the cleaned area at the front is found to be cleaned, the vacuum cleaner can be repositioned to clean other areas; if the cleaned area at the front is still not cleaned, it can be pushed forward again and the cleaning action of cleaning the same area can be repeated. Therefore, the use of the first light-emitting device 140 and the second light-emitting device 150 can also effectively improve cleaning efficiency.

[0055] In some alternative embodiments, see Figure 3The first light-emitting device 140 and the second light-emitting device 150 are located between the two laterally opposite ends of the brush body 120. Since both the first light-emitting device 140 and the second light-emitting device 150 are positioned between the two laterally opposite ends of the brush body 120, the light emitted by both is not overly concentrated near any one end of the brush body 120, resulting in a more reasonable light distribution and making it easier to see the dirt in various lateral positions. This effect is even more pronounced when both the first light-emitting device 140 and the second light-emitting device 150 are located in the middle of the brush body 120.

[0056] In some implementations, the second light-emitting device 150 is illuminated when the floor brush body 120 moves forward; the first light-emitting device 140 is illuminated when the floor brush body 120 moves backward. By illuminating a corresponding light-emitting device depending on the forward or backward movement of the floor brush body 120, the cleaning status can be monitored while saving energy.

[0057] For example, if an area has already been cleaned once, during a subsequent cleaning process, if the floor brush body 120 moves forward and the area behind it is the most recently cleaned area, the first light-emitting device 140 is turned off, and the second light-emitting device 150 is turned on to illuminate the most recently cleaned area; if the floor brush body 120 moves backward and the area in front of it is the most recently cleaned area, the second light-emitting device 150 is turned off, and the first light-emitting device 140 is turned on to illuminate the most recently cleaned area. This provides a more accurate picture of the cleaning process without requiring both light-emitting devices to be on. Therefore, in this embodiment, "cleaned area" also refers to the most recently cleaned area.

[0058] See Figure 2 The floor brush 100 also includes a connector 130 located on the floor brush body 120. The body 200 can rotate relative to the floor brush 100 through the connector 130, so that the vacuum cleaner can be in a flat position (at this time the body 200 is roughly parallel to the ground), which is suitable for cleaning low spaces.

[0059] In some other implementations, the first light-emitting device 140 and the second light-emitting device 150 are both in a light-emitting state as the brush body 120 moves forward or backward.

[0060] In some optional embodiments, the floor brush 100 includes a detection device electrically connected to a control board. The detection device is installed on the floor brush body 120 and is electrically connected to the first light-emitting device 140 and the second light-emitting device 150, respectively. The detection device is used to detect the travel direction of the floor brush body 120 and output a travel direction signal to the control board. The control board is used to control the first light-emitting device 140 and the second light-emitting device 150 to emit light selectively when triggered by the travel direction signal.

[0061] Based on the direction of travel detected by the detection device, the opening or closing of the first light-emitting device 140 and the second light-emitting device 150 can be controlled in a timely and effective manner, ensuring that the second light-emitting device 150 is turned on when the vacuum cleaner is pushed and the first light-emitting device 140 is turned on when the vacuum cleaner is pulled back, so that the pushing and pulling action is matched with the corresponding light-emitting device, thereby improving the user experience.

[0062] Of course, the control board can also control the first light-emitting device 140 and the second light-emitting device 150 to emit light synchronously when triggered by the direction of travel signal.

[0063] The detection device includes, but is not limited to, at least one of optical sensors, inertial sensors, and ultrasonic sensors. The optical sensor may be an infrared sensor, and the inertial sensor may be an accelerometer or a gyroscope.

[0064] The control board can be installed on the main unit 300 or on the floor brush body 120.

[0065] See Figure 2 In some optional embodiments, the vertical distance H between the center position of the light beam emitted by the first light-emitting device 140 and the surface to be cleaned, and the vertical distance between the center position of the light beam emitted by the second light-emitting device 150 and the surface to be cleaned are both less than or equal to 10 mm.

[0066] For example, the distance L1 or L2 here can be set independently to be less than 5mm or less than 8mm.

[0067] This low-altitude illumination of the ground enhances the scattering and reflection of light by small particles of debris. The enhanced interaction makes the small particles of debris stand out more under the illumination, improving the visibility of the debris.

[0068] See Figure 2 In some alternative embodiments, the cleaning component includes a roller brush 110, the angle between the vertical line connecting the center position of the light beam emitted by the first light-emitting device 140 to the axis of the roller brush 110 and the horizontal plane L2, and the angle between the vertical line connecting the center position of the light beam emitted by the second light-emitting device 150 to the axis of the roller brush 110 and the horizontal plane (see [reference]). Figure 2 In the middle α3), all are -45° to 45°. Here, the included angle can also be independently located between 0° and 45° (see...). Figure 2 (α1) or -45-0° (see α1) or -45-0° (see α1) Figure 2 Within the range of α2). This also effectively ensures that the light-emitting device illuminates the ground at a lower height, enhancing the scattering and reflection of light by small particles of waste, making the small particles of waste more prominent under the illumination of light, and improving the visibility of the waste.

[0069] Figure 3 and Figure 4They respectively showed different Figure 2 The other two structures of the floor brush 100.

[0070] In some optional embodiments, the vertical projections of the first light-emitting device 140 and the second light-emitting device 150 onto the horizontal plane are both located within the vertical projection range of the floor brush body 120 onto the horizontal plane, and the vertical projections of the first light-emitting device 140 and the second light-emitting device 150 onto a preset vertical surface are both located within the vertical projection range of the floor brush body 120 onto the preset vertical surface; wherein, the preset vertical surface is parallel to the lateral direction of the cleaning component and perpendicular to the horizontal plane. This is more suitable for applications such as... Figure 2 and Figure 3 The vacuum cleaner shown has dual roller brushes 110. The default vertical surface can be seen here. Figure 2 L4 is shown.

[0071] In other implementations, the vertical projection of the first light-emitting device 140 (or the second light-emitting device 150) onto the horizontal plane is within the range of the vertical projection of the brush body 120 onto the horizontal plane, and the vertical projection of the first light-emitting device 140 (or the second light-emitting device 150) onto a preset vertical surface is within the range of the vertical projection of the brush body 120 onto the preset vertical surface; wherein, the preset vertical surface is parallel to the lateral direction of the cleaning component and perpendicular to the horizontal plane. This is more suitable for applications such as... Figure 4 The vacuum cleaner shown has a single roller brush 110.

[0072] The vertical projections of the light-emitting devices (referring to at least one of the first light-emitting device 140 and the second light-emitting device 150) onto the horizontal plane are all within the range of the vertical projection of the floor brush body 120 onto the horizontal plane, which ensures that the light-emitting devices will not protrude forward from the floor brush body 120 (see...). Figure 2 The first light-emitting device 140 is located on the rear side of the vertical surface L3 tangent to the foremost position of the brush cover. This way, when the front edge of the vacuum cleaner is being cleaned, the light-emitting device will not affect the cleaning of the cleaning parts, reducing the problem of missed areas on the front edge. Moreover, if the vacuum cleaner encounters an obstacle while moving forward, the light-emitting device will not be the first to bear the impact force, which also provides a certain degree of protection for the light-emitting device.

[0073] The vertical projection of the light-emitting device onto the preset vertical surface is within the vertical projection range of the floor brush body 120 onto the preset vertical surface. This ensures that the light-emitting device does not protrude upwards from the highest point of the floor brush body 120, thus maintaining the original height of the floor brush body 120. The installation of the light-emitting device will not affect the floor brush body 120's ability to clean low spaces such as under beds and sofas. See also... Figure 5 The first light-emitting device 140 is located in area B formed by the dotted line and the brush cover 122, so that the first light-emitting device 140 neither protrudes forward from the brush body 120 nor protrudes upward from the highest position of the brush body 120.

[0074] In some alternative embodiments, see Figure 2 The floor brush body 120 includes a main housing 121 and a brush cover 122. The cleaning component is rotatably connected to the main housing 121. The brush cover 122 is connected to the main housing 121 and covers the cleaning component. The first light-emitting device 140 and the second light-emitting device 150 are both mounted on the brush cover 122. This configuration is more suitable for vacuum cleaners with dual roller brushes 110.

[0075] For vacuum cleaners with a single roller brush 110, see [link / reference]. Figure 4 One of the first light-emitting device 140 and the second light-emitting device 150 is mounted on the brush cover 122, and the other can be mounted on the floor brush body 120.

[0076] The brush cover 122 is located above the cleaning component and serves to prevent debris from leaking out under the centrifugal force generated by the rotation of the roller brush 110 and to prevent external debris from entering the floor brush 100. The lateral length of the brush cover 122 is approximately equal to the axial length of the roller brush 110, allowing for flexible placement of the light-emitting device. Furthermore, the brush cover 122 is generally detachable, allowing the light-emitting device to be installed on it and simultaneously removed when the brush cover 122 is disassembled, facilitating maintenance or replacement of the light-emitting device.

[0077] In some alternative embodiments, see Figure 5 At least one of the first light-emitting device 140 and the second light-emitting device 150 is installed on the outer wall of the brush cover 122 facing away from the receiving cavity.

[0078] Alternatively, in some optional embodiments, the brush cover 122 is provided with light-emitting holes, and at least one of the first light-emitting device 140 and the second light-emitting device 150 is located in the receiving cavity and installed on the inner wall of the brush cover 122 facing the receiving cavity. The light emitted by the first light-emitting device 140 and the second light-emitting device 150 respectively illuminates the surface to be cleaned through the corresponding light-emitting holes.

[0079] Or see Figure 6 In some alternative embodiments, the brush cover 122 includes at least two layers of cover 1221 stacked together, with at least one of the first light-emitting device 140 and the second light-emitting device 150 located between the two layers of cover 1221.

[0080] When the light-emitting device is at least partially installed on the inner wall of the brush cover 122 or between the two cover layers 1221, the overall integrity of the brush cover 122 is improved, resulting in a better user experience. When the light-emitting device is at least partially installed on the outer wall of the brush cover 122, it is more convenient to disassemble, repair, and replace the light-emitting device.

[0081] In some alternative embodiments, see Figure 1Both the first light-emitting device 140 and the second light-emitting device 150 include a light source 101 and a light-shaping component 102. The light-shaping component 102 is used to receive the light beam emitted by the light source 101 and guide the light beam to the surface to be cleaned, so that the light and shadow area of ​​the surface to be cleaned illuminated by the light source 101 is a fan-shaped area; the edges of the two lateral ends of the floor brush body 120 are located within the fan-shaped area, or the edges of the two lateral ends of the floor brush body 120 are located within the fan-shaped area (see...). Figure 3 Outside the desired fan-shaped area A1, the distance between the light source 101 and the boundary of the fan-shaped area is less than 20mm. This ensures that the light emitted by the light source 101 can cover the lateral areas on both sides of the front and rear of the brush 100 as much as possible, reducing or even eliminating blind spots at the lateral ends or front of the brush body 120 (see...). Figure 3 Undesirable sector region A2).

[0082] Preferably, the angle of the aforementioned sector region is 80°.

[0083] The light source 101 of the first light-emitting device 140 and the light source 101 of the second light-emitting device 150 can be independently configured as a laser diode or a light-emitting diode (LED). The number of light sources 101 in each light-emitting device can be one, two or more.

[0084] The light shaping component 102 can be a lens.

[0085] The light source 101 can be oriented forward or tilted at a certain angle to the ground.

[0086] In some alternative embodiments, see Figure 6 The first light-emitting device 140 and the second light-emitting device 150 both include a light source 101 and a control harness 141. The control harness 141 includes a first segment 1411 and a second segment. One end of the first segment 1411 is installed on the brush cover 122; one end of the second segment is electrically connected to the power supply and the second segment is electrically connected to the power supply or the control board; the first segment 1411 is installed on the brush cover 122, and the second segment is installed on the main housing 121; the brush cover 122 and the main housing 121 are detachably connected, and the other end of the first segment 1411 and the other end of the second segment are detachably connected.

[0087] When the brush cover 122 is connected to the main housing 121, the other end of the first segment 1411 and the other end of the second segment are electrically connected; when the brush cover 122 is disassembled from the main housing 121, the first segment separates from the main housing 121 along with the brush cover 122.

[0088] The control harness 141 is divided into two parts: a first segment 1411 and a second segment. When cleaning the brush cover 122, disassembling the cleaning components, or repairing or replacing the light-emitting device, the brush cover 122 can be removed, allowing the first segment 1411 and the second segment to be separated without tools. When cleaning is required, the brush cover 122 can be installed. The first segment 1411 and the second segment can also be electrically connected using plug-in methods, making it more convenient to use.

[0089] Furthermore, by utilizing the control wiring harness 141, the battery on the vacuum cleaner main unit 300 can power the light-emitting device, or a separate battery can be configured for the light-emitting device. The battery can be installed in a more spacious location such as the main housing 121, instead of being placed in a limited space such as the brush cover 122, which not only ensures the energy supply of the light-emitting device, but also makes the layout more reasonable.

[0090] One end of the first segment 1411 can be directly connected to either the power supply or the control board, or both. The power supply is used to power the light-emitting device, and the control board is used to control the light-emitting device to turn on or off.

[0091] In some alternative embodiments, the light source 101 includes a dust-detecting light source 101 capable of emitting green or blue light, or a sterilization light source 101 capable of emitting violet light. Alternatively, one of the two light-emitting devices may be a dust-detecting light source 101 and the other may be a sterilization light source 101.

[0092] The dust-detecting light source 101, which emits green or blue light, has a good dust-detecting effect. The sterilization light source 101 also has a certain dust-detecting effect, but at the same time, it also has a sterilization effect, which can sterilize the ground and reduce the odor generated during the cleaning process.

[0093] Without conflict, different embodiments or different technical features of this disclosure can be arbitrarily combined to form new embodiments.

[0094] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this utility model that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this utility model and do not limit the scope of protection of this utility model patent.
