[0037] Figure 2 The following is a block diagram of another embodiment of the vacuum cleaner head of the present application.

[0038] Figure 3 The following is a flowchart of an embodiment of the control method of the vacuum cleaner head of the present application. Detailed implementation manners

[0039] The present application provides a vacuum cleaner head, a vacuum cleaner, and a control method for the vacuum cleaner head. The following will describe in detail the vacuum cleaner head, the vacuum cleaner, and the control method for the vacuum cleaner head of the present application with reference to the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0040] Figure 1 The following is a block diagram of an embodiment of the vacuum cleaner head 10 of the present application. As Figure 1 shown, the vacuum cleaner head 10 includes: a controller 11, a display device 12, a ground detection device 13, and a dust detection device 14.

[0041] The controller 11 is electrically connected to the display device 12, the ground detection device 13, and the dust detection device 14. The controller 11 is configured to receive electrical signals from the display device 12, the ground detection device 13, and the dust detection device 14, and can control the display device 12, the ground detection device 13, and the dust detection device 14 to work. The controller 11 has a built-in control program to control the display device 12, the ground detection device 13, and the dust detection device 14 to work according to the preset control program. The controller 11 can also receive control signals sent from the outside and modify the built-in control program.

[0042] The display device 12 is used to display various types of information. The vacuum cleaner head 10 includes the display device 12, enabling the user to directly see the working state of the vacuum cleaner when using the vacuum cleaner head 10, which is convenient for the user. The display device 12 includes a display screen. The vacuum cleaner head 10 includes a housing, and the display device 12 is disposed on the housing of the vacuum cleaner head 10. In some embodiments, the display device 12 is disposed on the upper surface of the vacuum cleaner head 10, which is more conducive to the user observing the various types of information it displays. The display style and display content of the display device 12 are adjustable. The display device 12 includes an interactive display screen that can be touched or pressed by the user to generate corresponding interactive signals to modify its display content or display style. In some embodiments, the vacuum cleaner head 10 is communicatively connected to an external control device, such as a remote control or a mobile terminal. The user can set the display information of the display device 12 through the external control device.

[0043] The ground detection device 13 is used to detect the first feature information of the ground. The first feature information includes information such as the material, hardness, and smoothness of the ground. The ground detection device 13 is arranged at the front end in the forward direction of the vacuum cleaner head 10. When the vacuum cleaner head 10 is working, the ground detection device 13 can timely detect the first feature information of the ground.

[0044] The dust detection device 14 is used to detect the second feature information of the dust on the ground. The second feature information includes information such as the quantity, density, and type of the dust. In some embodiments, the dust detection devices 14 are symmetrically arranged on both sides of the vacuum cleaner head 10. In this way, when the vacuum cleaner head 10 is working, the dust detection devices 14 can detect the dust conditions on the ground on both sides of the vacuum cleaner head 10, with a large detection area and more accurate detection. In other embodiments, the dust detection devices 14 are asymmetrically arranged on both sides of the vacuum cleaner head 10. In still other embodiments, the dust detection device 14 is arranged on one side of the vacuum cleaner head 10, with more flexible detection and low cost.

[0045] The controller 11 is used to: control the display device 12 to display the first feature information and / or the second feature information. The first feature information detected by the ground detection device 13 and the second feature information detected by the dust detection device 14 are sent to the controller 11. The controller 11 sends the first feature information and the second feature information to the display device 12, and controls the display device 12 to display the first feature information and / or the second feature information. The controller 11 can also analyze and integrate the first feature information and the second feature information, and then control the display device 12 to display the first feature information and / or the second feature information after analysis and integration. The controller 11 can adjust its display state on the display device 12 according to the actual situations of the first feature information and the second feature information. For example, if the first feature information or the second feature information is in an abnormal state, the information in the abnormal state is preferentially and prominently displayed, so that the user can timely learn the abnormal information and prevent the vacuum cleaner head 10 from malfunctioning.

[0046] In some embodiments, the vacuum cleaner head 10 includes the display device 12, and the display device 12 can display the feature information corresponding to the ground and the dust, so that the user can learn the working state information of the vacuum cleaner by observing the vacuum cleaner head 10, which is convenient for the user to adjust the working state of the vacuum cleaner according to the specific situations of the ground and the dust, facilitating the user's use and improving the user experience.

[0047] The controller 11 also controls the display device 12 to display the fault information of the vacuum cleaner head 10, so that the user can timely learn the fault situation of the vacuum cleaner head 10.

[0048] Figure 2 The following shows the structural block diagram of another embodiment of the vacuum cleaner head 10 of the present application.

[0049] In some embodiments, the ground detection device 13 includes an ultrasonic detection device 131 for transmitting ultrasonic signals. The controller 11 is configured to: determine first characteristic information based on the signal intensity and the signal echo duration of the ultrasonic signals reflected by the ground.

[0050] When ultrasonic signals propagate in media with different hardnesses, their characteristics such as propagation speed and attenuation degree will be different. Generally, for ground materials with higher hardness, such as rocks and concrete, the propagation speed of ultrasonic signals in them is relatively fast and the attenuation is relatively small; while for ground materials with lower hardness, such as soil and sand, the propagation speed of ultrasonic signals is slower and the attenuation is more obvious. The controller 11 can make a rough judgment on the ground hardness by analyzing the changes in characteristics such as the propagation speed and attenuation degree of the ultrasonic signals after propagating on the ground.

[0051] The smoothness of the ground also affects the characteristics of ultrasonic signals. When the beam of ultrasonic signals irradiates the ground, a smooth ground will make the ultrasonic signals reflect more regularly, and the intensity and direction of the reflected waves are relatively concentrated; while a rough ground will cause the ultrasonic signals to undergo diffuse reflection, the intensity of the reflected waves will be relatively dispersed, and the intensity of the reflected waves is weak at certain angles. The controller 11 can obtain relevant information on the ground smoothness by analyzing the intensity distribution and scattering of the reflected wave signals. In this way, the controller 11 can more accurately determine the first characteristic information of the ground based on the changes in the characteristics of the ultrasonic signals reflected by the ground.

[0052] In some embodiments, the dust detection device 14 includes an infrared sensor for transmitting infrared signals. The controller 11 is configured to: determine second characteristic information based on the signal intensity of the infrared signals reflected by the ground.

[0053] The infrared sensor includes an infrared transmitting tube 141 and an infrared receiving tube 142. The infrared transmitting tube 141 includes an infrared emitting diode. The infrared transmitting tube 141 is used for transmitting infrared signals, and the infrared receiving tube 142 is used for receiving the infrared signals reflected by the ground. Infrared signals have specific wavelengths and intensities. When infrared signals propagate in the air between the dust detection device 14 and the ground and encounter dust particles, a scattering phenomenon will occur. The size, shape and properties of the dust particles will all affect the scattering intensity and direction of the infrared signals. Generally, larger-sized dust particles will cause stronger scattering of the infrared signals, while smaller-sized dust particles have relatively weaker scattering. The infrared receiving tube 142 is used for receiving the infrared signals scattered by the dust. The infrared sensor further includes a photodetector, which can convert the received infrared light signals into electrical signals and send them to the controller 11. The controller 11 determines the second characteristic information of the dust by analyzing this electrical signal.

[0054] The vacuum cleaner head 10 further includes a driving device 15 and a cleaning device 16. The driving device 15 is drivingly connected to the cleaning device 16. In some embodiments, the driving device 15 and the cleaning device 16 are drivingly connected through a transmission shaft. The driving device 15 includes a driving motor. The cleaning device 16 includes a brush head. The driving device 15 can drive the cleaning device 16 to work. For example, the driving device 15 can drive the brush head to rotate to clean the ground. In some embodiments, the driving device 15 is disposed at the center of the vacuum cleaner head 10, and for the area passed by the vacuum cleaner head 10, the driving device 15 can drive the cleaning device 16 to perform effective cleaning.

[0055] The driving device 15 is electrically connected to the controller 11. The controller 11 is configured to: control the display device 12 to display the first working information of the driving device 15.

[0056] The controller 11 is configured to control the driving device 15 to work. For example, the controller 11 controls the power of the driving device 15. The controller 11 also controls the display device 12 to display the first working information of the driving device 15, such as the power, gear position, battery level, etc. of the driving device 15. In this way, the user can conveniently obtain the working state of the driving device 15 through the display device 12, and can adjust the working of the driving device 15 according to its working state, which is convenient for the user to use.

[0057] The controller 11 is configured to: determine the first characteristic information according to the electrical signal of the ground detection device 13; and control the driving device 15 to drive the cleaning device 16 to work according to the first characteristic information.

[0058] The controller 11 controls the driving device 15 to drive the cleaning device 16 to work at different cleaning speeds and cleaning intensities according to the first characteristic information of the ground. For example, for a relatively hard and smooth ground (such as a tile), the cleaning device 16 can be controlled to work at a low speed and with a relatively low intensity; for a relatively soft and rough ground (such as a carpet), the cleaning device 16 can be controlled to work at a high speed and with a relatively high intensity. In this way, for different grounds, appropriate cleaning measures can be taken, which can save energy while ensuring the cleaning effect. At the same time, the cleaning device 16 is protected, preventing incorrect selection of the cleaning device 16 by human judgment, improving the service life of the cleaning device 16, and reducing the frequent replacement of the cleaning device 16.

[0059] The driving device 15 includes a brushed motor. The controller 11 can drive the brushed motor to work through a PWM signal according to the first characteristic information such as the material and hardness of the ground, control the rotation speed of the brushed motor, and adjust the power of the brushed motor in real time according to the first characteristic information of the ground.

[0060] The controller 11 is configured to: determine second feature information based on the electrical signal of the dust detection device 14; and control the driving device 15 to drive the cleaning device 16 to operate according to the second feature information.

[0061] The controller 11 controls the driving device 15 to drive the cleaning device 16 to operate at different cleaning speeds and cleaning intensities according to the second feature information of the dust. For example, if the amount of dust is small and the volume is small, the cleaning device 16 can be controlled to operate at a low speed and with a low intensity; if the amount of dust is large and the volume is large, the cleaning device 16 can be controlled to operate at a high speed and with a high intensity. In this way, for different dust conditions, appropriate cleaning measures can be taken, which can save energy while ensuring the cleaning effect, and at the same time, protect the cleaning device 16 and extend the service life of the cleaning device 16.

[0062] In some embodiments, the controller 11 is configured to: control the driving device 15 to drive the cleaning device 16 to operate according to the first feature information and the second feature information.

[0063] By comprehensively considering the first feature information of the ground and the second feature information of the dust, the working state of the cleaning device 16 can be controlled according to the specific conditions of the ground and the dust, which can ensure the cleaning effect and save energy.

[0064] The vacuum cleaner head 10 further includes a lighting source 17 electrically connected to the controller 11, which is disposed around the edge of the vacuum cleaner head 10. The controller 11 is further configured to: control the lighting source 17 to operate according to the second feature information.

[0065] The lighting source 17 is used to provide illumination. When the vacuum cleaner head 10 is operating, the lighting source 17 is turned on to illuminate the ground and the dust. According to the second feature information of the dust, the controller 11 controls the lighting source 17 to be in different working states. For example, according to the amount of dust, the lighting source 17 can be controlled to emit different colors of light so that the user can clearly know the dust situation. The lighting source 17 can also provide supplementary lighting when the ambient light is relatively dim, providing a bright working environment for the vacuum cleaner head 10.

[0066] The lighting source 17 includes green light beads. The green light beads include lenses. When the amount of dust on the ground is small, the green light beads are controlled to turn on to remind the user that this area does not need to be cleaned continuously. When the amount of dust on the ground is large, the green light beads are controlled to turn off, so that the user can clearly know the dust situation.

[0067] The vacuum cleaner head 10 further includes a control board 18 and a power supply terminal 19. The power supply terminal 19 is used to connect to a power supply. The power supply can be an external power supply to supply power to the power supply terminal 19.

[0068] The control board 18 includes a controller 11 and a voltage conversion unit 181. The voltage conversion unit 181 is electrically connected to the controller 11, the display device 12, the ground detection device 13, and the dust detection device 14, and the power supply terminal 19 is electrically connected to the voltage conversion unit 181. The voltage conversion unit 181 can convert the voltage. The voltage conversion unit 181 converts the output voltage of the power supply terminal 19 into the power supply voltages required by the controller 11, the display device 12, the ground detection device 13, and the dust detection device 14 to supply power to the above components. The voltage conversion unit 181 includes a DCDC voltage conversion module. The voltage conversion unit 181 further includes a voltage stabilizing circuit. The output voltage of the power supply passes through the voltage stabilizing circuit and is transmitted to electrical appliances such as the controller 11.

[0073] The main body includes a controllable switch. The controller 11 is further configured to: in response to the closure of the controllable switch, control the power supply terminal 19 to output a power supply voltage and initialize the control board 18.

[0074] The controller 11 is configured to: control the display device 12 to display the second working information of the main body.

[0075] The controller 11 can control the display device 12 to display the second working information of the main body, such as the remaining power of the power supply. The main body may further include other components, and the controller 11 controls the display device 12 to display the working states of other components. In this way, the user can obtain richer and more comprehensive information from the display device 12, improving the user experience.

[0083] Control the vacuum cleaner head to enter the current working mode, and control the display device to display the current working mode of the vacuum cleaner head.

[0084] The environmental information is the information of the working environment where the vacuum cleaner head is located.
