[0033] The present invention is further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, the direction identification device in this embodiment includes a shell 1, a magnetic member 2, and a linear Hall sensor 3.

[0035] The housing 1 is provided with an active cavity 10, specifically, the housing 1 comprises a main body 11 facing an opening at one end and a cover 12 covering the opening, and the active cavity 10 in this embodiment is arranged in the main body 11. The magnetic member 2 is movably arranged in the active cavity 10. The structure of the main body 11 and the cover 12 of the housing 1 facilitates the installation of the magnetic member 2 therein.

[0036] The linear Hall sensor 3 is arranged outside the shell 1 along the extension direction of the active cavity 10, and the linear Hall sensor 3 detects and obtains different signals based on the different positions of the magnetic member 2 in the active cavity 10. In order to facilitate the identification of the direction, the extension direction of the active cavity 10 is the direction to be detected, and the magnetic member 2 also reciprocates along the extension direction of the active cavity 10 in the active cavity 10. If the direction identification device is used to detect the forward or backward direction, the active cavity 10 in the direction identification device is arranged on the application device along the direction of extension to the front and back. If the direction identification device is used to detect the left or right direction, the active cavity 10 in the direction identification device is arranged on the application device along the direction of extension to the left and right.

[0037] In order to ensure the stability of the installation of the linear Hall sensor 3, a groove 111 is provided in the area corresponding to the active cavity 10 on the housing 1, and the linear Hall sensor 3 is arranged in the groove 111. In this embodiment, the groove 111 is specifically provided on the top surface of the housing 1 corresponding to the extension direction of the active cavity 10. This facilitates the linear Hall sensor 3 to detect the changing signal based on the magnetic member 2 being in different positions in the active cavity 10.

[0038] In addition, in order to avoid unstable air pressure in the shell 1 due to airtightness, which in turn affects the inertial movement of the magnetic member 2 as the shell 1 moves, and to ensure that the magnetic member 2 can slide smoothly in the active cavity 10 based on the movement of the shell 1, in this embodiment, a vent hole 112 is provided on the main body 11 to ensure that the active cavity 10 in the main body 11 is always connected to the external atmosphere. At the same time, in order to avoid the influence of water and debris, the vent hole 112 can be provided at a position where water is not suitable, such as a corner of the main body 11.

[0039] In addition, if the magnetic member 2 is directly placed in the active cavity 10, the friction between the magnetic member 2 and the active cavity 10 is relatively large. When the moving speed of the housing 1 is low, the magnetic member 2 is prone to not move due to the friction, which will affect the accuracy of the direction recognition detection. Based on this, it is necessary to reduce the friction of the magnetic member 2 relative to the inner wall of the active cavity 10. In this embodiment, in order to ensure the stability of the moving direction of the magnetic member 2, a carrier 4 that can reciprocate along the extension direction of the active cavity 10 is provided in the active cavity 10, and the magnetic member 2 is arranged on the carrier 4 facing the linear Hall sensor 3. In order to reduce the friction of the magnetic part 2 when it moves in the active cavity 10 and ensure its smooth sliding, the carrier 4 includes a mounting frame 41 and a wheel assembly 42 arranged at the bottom of the mounting frame 41. The magnetic part 2 is arranged on the mounting frame 41, and the wheel assembly 42 is in rolling contact with the cavity wall of the active cavity 10. The contact area is small and the friction is small, so that the mounting frame 41 can move inertially with the movement of the shell 1, thereby driving the magnetic part 2 to move in the active cavity 10, making it convenient for the linear Hall sensor 3 to detect the signal change of the magnetic part 2 to achieve direction recognition.

[0040] In order to facilitate the installation of the magnetic component 2 and ensure the stability of the installation of the magnetic component 2 on the mounting frame 41 , a limiting groove 411 is provided on the mounting frame 41 , and the magnetic component 2 is arranged in the limiting groove 411 .

[0041] In addition, a signal processing circuit board is provided on the shell 1, and the linear Hall sensor 3 is electrically connected to the signal processing circuit board. The signal processing circuit board can process the signal detected by the linear Hall sensor 3 and then transmit it to the processor of the application device, thereby facilitating the processor to perform direction recognition work.

[0042] The direction identification device is provided with a movable magnetic part 2 and a linear Hall sensor 3 that interacts with the magnetic part 2. When in use, the linear Hall sensor 3 detects and obtains different signals based on the different positions of the magnetic part 2 in the active cavity 10. In this way, as the magnetic part 2 moves in the active cavity 10, the signal change detected by the linear Hall sensor 3 can determine the moving direction of the magnetic part 2 in the active cavity 10, and then determine the moving direction of the application device. In this way, the application device can perform intelligent control of multiple functions based on the determination of the moving direction. The direction identification device can be set at any position of the application device, especially for some application devices with special requirements such as waterproofing, and its setting position is highly flexible. In addition, based on the cooperation of the linear Hall sensor 3 and the magnetic part 2, the direction change of the application device can be detected in real time and accurately, and the moving direction can be obtained quickly, avoiding the situation of misjudgment.

[0043] When the direction identification device is used, it is installed on the application equipment and moves synchronously with the application equipment.

[0044] The direction identification method of the above-mentioned direction identification device is as follows: Initialize the relationship between the detection signal of the linear Hall sensor 3 and the position of the magnetic member 2 in the active cavity 10, and the relationship information can be obtained by testing during the product testing process.

[0045] When the application device is turned on, the linear Hall sensor 3 obtains an initial detection signal based on the position of the magnetic part 2. When the application device moves, the housing 1 moves synchronously with the application device, and the magnetic part 2 moves in the active cavity 10 based on inertia, so that the position of the magnetic part 2 relative to the linear Hall sensor 3 will change. The linear Hall sensor 3 obtains a real-time detection signal based on the real-time position of the magnetic part 2, and determines the moving direction of the magnetic part 2 in the active cavity 10 according to the change value of the real-time detection signal, and then determines the moving direction of the application device according to the moving direction of the magnetic part 2 in the active cavity 10. This direction recognition method can detect the direction change of the application device in real time and accurately, which is conducive to the reliability and precision control of the application device.

[0046] The direction recognition method of the present invention can detect the direction change of the application device in real time and accurately, which is beneficial to the reliability and accuracy control of the application device.

[0047] This embodiment also relates to a cleaning machine, including a housing 5 and a direction identification device as described above. The direction identification device can be installed at any position of the housing 5. In order to avoid affecting other components, the direction identification device in this embodiment is installed on the upper surface of the housing 5.

[0048] The cleaning machine also includes a processor and a memory. The processor is electrically connected to the memory and the linear Hall sensor 3. The memory stores a computer program for running on the processor. When the processor executes the computer program, the aforementioned direction recognition method is implemented. During operation, the processor obtains the detection signal transmitted by the linear Hall sensor 3, and then realizes direction recognition based on the computer program. The cleaning machine in the present invention uses the direction recognition device, which can perform various intelligent function controls such as power assistance and cleaning based on accurate and real-time detection of direction, with high control accuracy.

[0049] The present invention also relates to an electronic device, comprising a memory and a processor, wherein the memory stores a computer program for running on the processor, and the processor implements the above-mentioned direction recognition method when executing the computer program.

[0050] The present invention also relates to a computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the direction identification method described above is implemented.
