DETAILED DESCRIPTION OF THE INVENTION

[0019] It should be understood that the specific examples described herein are used only to illustrate the present application and are not to be used to limit the present application.

[0020] In the prior art, when using an ultrasonic therapy device, if the ultrasonic therapy head continuously treats one point on the skin, it is easy to cause skin burns, so a displacement sensor needs to be installed on the ultrasonic therapy head, and when the displacement sensor detects that the ultrasonic therapy head is moving, treatment can be started, otherwise the transducer is turned off.

[0021] However, this method has some drawbacks, for example, when a user uses the ultrasonic therapy head by himself, if the user moves the entire ultrasonic therapy device by himself, the system may determine that the ultrasonic therapy head has moved relative to the skin surface even though the ultrasonic therapy head has not moved relative to the skin surface, and the transducer may continue to operate, which may cause burns to the user. In other words, the accuracy of relative displacement detection of existing ultrasonic therapy heads is not high.

[0022] This application provides a solution, in this embodiment, the ultrasonic therapy device obtains the displacement data of the ultrasonic therapy head by the displacement sensor, then compares the displacement data of the ultrasonic therapy head with the preset displacement data, and simultaneously determines whether the ultrasonic therapy head has moved, and determines whether the movement has occurred based on the current contact data obtained by the contact sensor. That is, this application combines the displacement sensor and the contact sensor to determine the contact state between the ultrasonic therapy head and the human skin from multiple dimensions, thereby more accurately determining whether the ultrasonic therapy head has contact with the human skin, and controlling the ultrasonic therapy head to output ultrasonic energy in a timely manner, which is advantageous to improving the safety of the use of the ultrasonic therapy device.

[0025] It should be noted that although a logical order is depicted in the flow diagrams, in some cases the steps may be performed in a different order than that depicted or described herein.

[0026] In this first embodiment, the ultrasound treatment device comprises: an ultrasonic treatment head 100 used to output ultrasonic energy; a displacement sensor 200 provided on the handle of the ultrasonic therapy head or the ultrasonic therapy device, for collecting ultrasonic therapy head displacement data of the ultrasonic therapy head; a contact sensor 300 provided on the ultrasonic treatment head, for collecting current contact data between the ultrasonic treatment head and the corresponding human skin; The method includes a processor 400, a memory, and a control program for an ultrasonic therapy head stored in the memory, the control program for the ultrasonic therapy head implementing steps of a control method for an ultrasonic therapy head when executed by the processor.

[0027] In some embodiments, the contact sensor includes a pressure sensor, a capacitance sensor, and an infrared distance sensor, but the type of contact sensor is not limited here, and at least one of the contact sensors is required.

[0028] Please refer to FIG. 2, which is a structural schematic diagram of an ultrasound treatment device in a hardware operating environment according to an embodiment of the present application.

[0029] As shown in FIG. 2 , the ultrasound therapy device may include a processor 1001 such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005.

The user interface 1003 includes input units such as a display and a keyboard, and optionally, the user interface 1003 may also include a standard wired interface or a wireless interface.

The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM) such as a magnetic disk memory. Optionally, the memory 1005 may be a storage device independent of the processor 1001.

[0030] As will be appreciated by those skilled in the art, the structure shown in FIG. 2 is not intended to limit the scope of the ultrasound treatment device, which may have more or fewer components than those shown, may combine some components, or may have a different component layout.

[0031] As shown in FIG. 2, the memory 1005, which is a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and a control program for the ultrasonic treatment head.

[0032] In the ultrasonic therapy device shown in Figure 2, the network interface 1004 is mainly used for data communication with the network server, and the user interface 1003 is mainly used for exchanging data with the user. In the present application, the processor 1001 and memory 1005 of the ultrasonic therapy device may be provided in the ultrasonic therapy device, and the ultrasonic therapy device calls the control program of the ultrasonic therapy head stored in the memory 1005 by the processor 1001 to execute the control method of the ultrasonic therapy head according to the embodiment of the present application.

[0033] Based on the above hardware structure of the ultrasonic therapy device, but not limited thereto, the present application provides a first embodiment of a method for controlling an ultrasonic therapy head. Referring to Figure 3, Figure 3 shows a flow diagram of the first embodiment of the method for controlling an ultrasonic therapy head of the present application.

[0034] It should be noted that although a logical order is depicted in the flow diagrams, in some cases the steps may be performed in a different order than that depicted or described herein.

[0035] In this embodiment, a method for controlling an ultrasonic treatment head is used in an ultrasonic treatment device, The ultrasound treatment device comprises: an ultrasonic treatment head 100 used to output ultrasonic energy; a displacement sensor 200 provided on the handle of the ultrasonic therapy head or the ultrasonic therapy device, for collecting ultrasonic therapy head displacement data of the ultrasonic therapy head; a contact sensor 300 provided on the ultrasonic treatment head, for collecting current contact data between the ultrasonic treatment head and the corresponding human skin; The method provides a control method for an ultrasonic treatment head, including the following steps S10 to S30. S10: Determine whether the ultrasonic treatment head is moving based on the current displacement data of the ultrasonic treatment head collected by the displacement sensor. It can be understood that the implementation body of this embodiment is an ultrasonic therapy device. The displacement data of the ultrasonic therapy head specifically refers to the spatial movement data of the ultrasonic therapy head when the user uses the ultrasonic therapy device. The ultrasonic therapy device collects the displacement data of the ultrasonic therapy head through a displacement sensor.

[0036] The current contact data specifically refers to the contact data between the ultrasonic therapy head and the human skin when the user uses the ultrasonic therapy device. The ultrasonic therapy device collects the current contact data through a contact sensor, which includes a pressure sensor, a capacitance sensor, or an infrared distance sensor.

[0037] As can be understood, the ultrasonic therapy device collects the displacement data of the ultrasonic therapy head by a displacement sensor, that is, the displacement sensor monitors whether the ultrasonic therapy head is moving. If the displacement data of the ultrasonic therapy head collected by the displacement sensor is zero, it is determined that the ultrasonic therapy head is continuously treating one point on human skin, and in this case, it is likely to cause burns on the user's skin.

[0038] S20: Determine the contact state between the ultrasonic treatment head and the human skin based on the current contact data of the ultrasonic treatment head collected by the contact sensor. It is understandable that the ultrasonic therapy head moves in space, that is, displacement data greater than 0 does not mean that the ultrasonic therapy head is in contact with human skin. For example, when a user moves the entire ultrasonic therapy device by himself, if the ultrasonic therapy head does not contact the human skin or remains at a specific point on the human skin for a long time, the ultrasonic therapy head will move in space. In this case, the displacement sensor can still detect displacement data greater than 0. Therefore, in order to more accurately determine the state of the ultrasonic therapy head, it is necessary to simultaneously collect current contact data between the ultrasonic therapy head and the human skin.

[0039] It can be understood that in the process of user moving the ultrasonic therapy head, when the ultrasonic therapy head contacts the human skin, the ultrasonic therapy head and the human skin will necessarily be in contact, and at this time, the contact sensor will necessarily detect the contact data.Therefore, the ultrasonic therapy device uses the contact sensor to collect the contact data between the ultrasonic therapy head and the human skin, and determine the contact state between the ultrasonic therapy head and the human skin while collecting the movement data of the ultrasonic therapy head.

[0040] S30: Controlling the ultrasonic therapy head to start or stop outputting ultrasonic energy based on the current displacement data and the current contact data.

[0041] As can be understood, the ultrasonic therapy head includes a stopped state and an activated state. When the ultrasonic therapy head is in the stopped state, the ultrasonic therapy head does not output ultrasonic energy. When the ultrasonic therapy head is in the activated state, the ultrasonic therapy head outputs ultrasonic energy. When the ultrasonic therapy device determines that the ultrasonic therapy head is in contact with human skin, it controls the ultrasonic therapy head to output ultrasonic energy.

[0042] In this embodiment, the ultrasonic therapy device uses a displacement sensor to obtain current displacement data of the ultrasonic therapy head, and a contact sensor to obtain current contact data of the ultrasonic therapy head. The ultrasonic therapy device controls the start or stop of the ultrasonic therapy head based on the current displacement data and the current contact data. The ultrasonic therapy head's displacement data is compared with a preset displacement data to determine whether the ultrasonic therapy head has moved. The contact status between the ultrasonic therapy head and human skin is determined based on the current contact data obtained by the contact sensor. The comparison of the current displacement data and the current contact data is unsequential. In other words, the present application uses a combination of a displacement sensor and a contact sensor to determine the contact status between the ultrasonic therapy head and human skin from multiple dimensions, thereby more accurately determining the operating status of the ultrasonic therapy head on human skin and controlling the ultrasonic therapy head to output ultrasonic energy, which is advantageous for improving the safety of the ultrasonic therapy device.

[0043] the contact sensor includes a pressure sensor, and the current contact data is current pressure data collected by the pressure sensor; In this embodiment, the contact sensor includes a pressure sensor, and the current contact data of the ultrasonic therapy head is current pressure data collected by the pressure sensor.

[0044] It can be understood that the contact sensor includes a pressure sensor, which can be used to collect current pressure data between the ultrasonic therapy head and human skin, and the ultrasonic therapy device can determine the contact state between the ultrasonic therapy head and human skin based on the current pressure data collected by the pressure sensor.

[0045] In this embodiment, after the ultrasonic therapy head is moved, the ultrasonic therapy device determines the contact state between the ultrasonic therapy head and human skin based on the current pressure data collected by the pressure sensor, thereby more accurately determining the contact state between the ultrasonic therapy head and human skin, and controlling the ultrasonic therapy head to output ultrasonic energy, which is advantageous to improving the safety of using the ultrasonic therapy device.

[0046] Based on the above embodiment, the present application provides a second embodiment of a method for controlling an ultrasonic therapy head. Referring to Figure 4, Figure 4 shows a flow diagram of the second embodiment of the method for controlling an ultrasonic therapy head of the present application.

[0047] In this embodiment, step S20 further includes the following steps S21 and S22. S21: Determine whether the current pressure data is equal to or greater than a preset pressure value. S22: If the current pressure data is equal to or greater than the preset pressure value and the current displacement data is greater than 0, control the ultrasonic treatment head to output ultrasonic energy.

[0048] As can be understood, the preset pressure value is a numerical value preset by a user. After the pressure sensor acquires the current pressure data, the ultrasonic therapy device compares the preset pressure value with the current pressure data collected by the pressure sensor. If the current pressure data is equal to or greater than the preset pressure value, this indicates good contact between the ultrasonic therapy head and the human skin, and the ultrasonic therapy device controls the ultrasonic therapy head to output ultrasonic energy. In this embodiment, the ultrasonic therapy device compares the current pressure data with the preset pressure value, which is advantageous for accurately determining good contact between the ultrasonic therapy head and the human skin and accurately controlling the ultrasonic therapy head to output ultrasonic energy. In this embodiment, if the current pressure data indicates a poor contact state, i.e., the current pressure data becomes smaller than the preset pressure value, the ultrasonic therapy head is controlled to stop outputting ultrasonic energy, thereby improving the safety of the ultrasonic therapy device.

[0049] As an example, step S20 specifically includes the following steps S23 and S24. S23: Generate a pressure change graph based on the historical pressure data collected by the pressure sensor and the current pressure data, and determine whether the ultrasonic treatment head is sliding in the treatment area based on the pressure change graph.

[0050] S24: A plurality of consecutive pressure data including the current pressure data is selected from the pressure change graph. determining that the ultrasonic therapy head is sliding in the treatment area because the successive pressure data are at least partially different, and when the current displacement data is greater than 0, controlling the ultrasonic therapy head to output ultrasonic energy; If the plurality of successive pressure data are all the same and it is determined that the ultrasonic treatment head is not sliding on the treatment area, the ultrasonic treatment head is controlled to stop outputting ultrasonic energy.

[0051] It can be understood that the pressure sensor can only collect current pressure data. When the pressure sensor continuously collects pressure data during the user's use of the ultrasonic therapy device, the pressure sensor stores the pressure data in memory as historical pressure data. At this time, the ultrasonic therapy device can generate a pressure change graph based on the historical pressure data collected by the pressure sensor and the current pressure data. The ultrasonic therapy device determines multiple pressure data from the pressure change graph, where the multiple pressure data includes current pressure data. If the multiple pressure data are at least partially different, it determines that the ultrasonic therapy head is sliding within the treatment area. If the multiple pressure data are all the same, it determines that the ultrasonic therapy head is not sliding within the treatment area. In this case, the ultrasonic therapy head may be staying at a specific position on the human skin for a long time, and the current displacement data may be greater than 0. Even if the user holds and moves the ultrasonic therapy head at this time, the ultrasonic therapy head must be controlled to immediately stop outputting energy because the ultrasonic therapy head has been staying at a specific position on the human skin for a long time, thereby avoiding burns to the user. When the ultrasonic treatment head slides in the treatment area and the displacement data collected at this time is greater than 0, that is, when the ultrasonic treatment head is being used normally, the ultrasonic treatment head is controlled to output ultrasonic energy.

[0052] In this embodiment, the ultrasonic therapy device generates a pressure change graph according to the historical pressure data and the current pressure data, and then visually judges whether the current pressure data fluctuates in the pressure change graph to determine whether the ultrasonic therapy head slides in the treatment area, and when the ultrasonic therapy head moves in the treatment area, that is, when the ultrasonic therapy head is used normally, the ultrasonic therapy head can be accurately controlled to output ultrasonic energy. It can be understood that using other similar data processing methods to determine whether the ultrasonic therapy head slides in the treatment area from the pressure change graph also falls within the protection scope of this embodiment.

[0053] As a specific embodiment, in this embodiment, step S20 further includes the following steps S25 and S26. S25: Based on the historical pressure data collected by the pressure sensor and the current pressure data, determine the pressure difference between any two adjacent times within a preset period, and obtain at least two pressure change values. S26: Determine whether the ultrasonic treatment head is sliding on the treatment area based on the at least two pressure change values.

[0054] As can be understood, the preset period may be set by an authorized user, for example, the preset period may be 1 minute or 5 minutes, but the preset period is not limited herein. The pressure change value is the pressure difference between any two adjacent times within the preset period. The pressure change value may be at least two or more, but the number of pressure change values ​​is not limited herein. The ultrasonic therapy device can determine whether the ultrasonic therapy head is sliding on the treatment area based on the at least two pressure change values.

[0055] In this embodiment, the ultrasonic therapy device determines whether the ultrasonic therapy head is sliding in the treatment area based on at least two pressure change values, thereby accurately determining whether the ultrasonic therapy head is in use.

[0056] As a specific embodiment, in this embodiment, step S26 specifically includes the following steps S261 and S262. S261: If all the pressure change values ​​are zero, determine that the ultrasonic treatment head is not sliding in the treatment area. S262: Control the ultrasonic treatment head to stop outputting ultrasonic energy.

[0057] It can be understood that if the ultrasonic therapy head determines that all pressure change values ​​are zero, it means that the pressure has not changed within a preset period, and the ultrasonic therapy device determines that the ultrasonic therapy head is not sliding in the treatment area, and it should immediately control the ultrasonic therapy head to stop outputting ultrasonic energy to ensure the safety of the user; if all pressure change values ​​are not zero, it means that the pressure has changed within a preset period, and it should further determine that the ultrasonic therapy device is sliding in the treatment area, and it should then control the ultrasonic therapy head to output ultrasonic energy.

[0058] Illustratively, when a user is using the ultrasonic therapy head and walking, the displacement sensor collects displacement data of the ultrasonic therapy head, and at this time, the ultrasonic therapy device determines that multiple consecutive pressure change values ​​are zero based on the pressure data collected by the pressure sensor, in which case it determines that the ultrasonic therapy head is not sliding in the treatment area, and further, the ultrasonic therapy device controls the ultrasonic therapy head to immediately stop outputting ultrasonic energy.

[0059] In this embodiment, the ultrasonic therapy device can accurately determine whether the ultrasonic therapy head is sliding in the treatment area by determining whether all pressure change values ​​are zero, and further accurately control the ultrasonic therapy head.

[0060] As a specific embodiment, in this embodiment, step S10 specifically includes steps S11, S12, and S13. S11: Obtain the moving speed value of the ultrasonic treatment head. S12: Determine whether the moving speed value is equal to or greater than a preset moving speed value. S13: If the moving speed value is equal to or greater than the preset moving speed value, determine that there is movement in the ultrasonic treatment head.

[0061] It can be understood that the displacement sensor can collect the moving speed value of the ultrasonic therapy head, and the preset moving speed value is a numerical value preset by an authorized user. The ultrasonic therapy device determines whether the moving speed value is equal to or greater than the preset moving speed value to determine whether the movement of the ultrasonic therapy head is valid. If the moving speed value is equal to or greater than the preset moving speed value, it is determined that the ultrasonic therapy head has valid movement, and if the moving speed value is less than the preset moving speed value, it is determined that the ultrasonic therapy head has no valid movement.

[0062] In this embodiment, the ultrasonic therapy device can more accurately determine whether there is effective movement of the ultrasonic therapy head by determining whether the movement speed value is equal to or greater than a preset movement speed value.
