DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] The current manual opening device has certain requirements on the user's strength and skills, which makes it inconvenient to use. Although there are some electric opening devices on the market that can reduce the requirements on the user's strength and skills, the user is still required to judge whether the opening action is completed during use and manually stop the device when completed, which makes it very inconvenient to use.

[0027] In view of the above problems, the present application provides an electric opening device with one-button start and stop, which detects the posture information of the electric opening device in real time during operation by setting a posture sensor, and promptly controls the electric opening device to stop working when it is determined that the electric opening device has returned to the starting point based on the posture information, thereby reducing the user's operation complexity and improving the user's experience. The following non-limiting description of the specific implementation scheme is given through several examples or embodiments.

[0028] Some embodiments of the present application provide an electric start-stop device with a one-button start, referring to Figure 1-Figure 2 , Figure 1 An exploded view of an electric start-stop device with one-button start provided by an embodiment of the present application; Figure 2 A circuit diagram of an electric opening device with one-button start and stop provided in one embodiment of the present application.

[0029] like Figure 1-Figure 2 As shown, the one-button start-stop electric opening device of this embodiment includes: a housing, a control switch 3, a main control module 4, a posture sensor 5, a drive device 6, a power module 7 and a cutter head 8.

[0030] in,

[0031] The control switch 3, the attitude sensor 5 and the drive device 6 are all electrically connected to the main control module 4; the power module 7 is used for power supply;

[0032] The control switch 3 is used to send a trigger signal to the main control module 4 according to the user operation, and the main control module 4 is used to control the drive device 6 to start and drive the cutter head 8 to operate according to the trigger signal to open the container;

[0033] The posture sensor 5 is used to detect the posture information of the electric opening device and send the posture information to the main control module 4. The main control module 4 is also used to control the driving device 6 to stop running when it is determined that the electric opening device returns to the starting point according to the posture information.

[0034] When the electric opening device is working, the user first places it on the opening side of the container to be opened, and the cutter head 8 contacts the opening side of the container. Then the user starts the electric opening device through the control switch 3. After the main control module 4 receives the trigger signal generated by the control switch 3, it controls the drive device 6 to be powered on and run. When the drive device 6 is running, a driving force is generated. The driving force is applied to the cutter head 8 so that the cutter head 8 cuts the opening side of the container, and the electric opening device as a whole moves in a circular shape along the opening side of the container. According to the shape of the opening side of the container, the moving trajectory can be a circle, an ellipse or a rounded rectangle. In addition, during the movement of the electric opening device, the posture sensor 5 detects the posture information in real time, including information such as direction, angle and moving distance. The detected posture information is sent to the main control module 4 for processing. The main control module 4 can process and calculate based on the real-time posture information and the posture information in the initial state, so as to determine whether the electric opening device returns to the starting point (that is, whether the electric opening device has completed a complete circular trajectory movement). If so, the drive device 6 is automatically controlled to stop running, that is, the electric opening device is controlled to stop working.

[0035] It can be seen that the above-mentioned electric opening device detects the posture information of the electric opening device through the posture sensor 5, and is processed by the main control module 4, so that the real-time posture of the electric device during the working process can be determined. When it is determined that the electric opening device returns to the starting point, it can be determined that the electric opening device has completed the opening action, so that the electric opening device can be controlled to stop running. With such a setting, the container can be opened automatically with one button, that is, the user only needs to control the device to start, and does not need to judge whether the opening action is completed by himself, nor does he need to manually control the stop, which can effectively reduce the user's difficulty and operation, and improve the user's experience.

[0036] Specifically, Figure 1 As shown, the control switch 3 includes a button 31 and a button PCB board 32, wherein the button 31 is exposed outside the housing, and the button PCB board 32 is arranged inside the housing and electrically connected to the main control module 4. When the user presses the button 31, the button PCB board 32 is triggered to generate a trigger signal, which is sent to the main control module 4 to trigger the operation of the main control module 4.

[0037] The main control module 4 is responsible for the main control functions of the entire device. Figure 2 As shown, the main control module 4 may include an MCU (Micro Controller Unit), such as an MCU of model APT32F1028F8P6.

[0038] In addition, in some embodiments, the attitude sensor 5 may include a three-axis accelerometer and a three-axis gyroscope, which are used to measure the motion state and attitude angle of the electric opening device in three directions respectively. Based on the motion state and attitude angle in three directions, information such as the acceleration and direction of the electric opening device can be determined, thereby further determining whether the electric opening device returns to the starting point.

[0039] Furthermore, the attitude sensor 5 may be a sensor product of model MPU-6050, which is a six-axis inertial motion sensor that integrates a three-axis accelerometer and a three-axis gyroscope and has the characteristics of high accuracy, high sensitivity, and high stability.

[0040] In addition, in some embodiments, Figure 1 As shown, the driving device 6 may include a motor 61, a driving chip 62 and a transmission component 63.

[0041] The driving chip 62 is electrically connected to the main control module 4 and the motor 61, and can obtain the control signal of the main control module 4, and drive the motor 61 to run or stop according to the control signal. The driving chip 62 can be, but is not limited to, a driving chip of model SA8336.

[0042] The output shaft of the motor 61 is connected to the cutter head 8 through the transmission assembly 63. Through the transmission assembly 63, the power of the motor 61 can be transmitted to the cutter head 8 to drive the cutter head 8 to move.

[0043] Furthermore, if Figure 1 As shown, the transmission assembly 63 includes a plurality of transmission gears. Through the step-by-step transmission of the plurality of transmission gears, the power of the motor 61 can be transmitted to the cutter head 8. The transmission gears are fixed inside the housing through a gear shaft 731. Furthermore, the drive device 6 also includes a cutter head linkage 85, and the transmission assembly 63 is connected to the cutter head 8 through the cutter head linkage 85.

[0044] In addition, if Figure 1 As shown, the electric opening device also includes a cutter head screw 81, a cutter head nut 82, a cutter head support seat 83, a cutter head base 84 and a cutter shaft assembly 86. Among them, the cutter head 8 is fixed to the cutter head support seat 83 and the cutter head base 84 by the cutter head screw 81 and the cutter head nut 82, and is connected to the transmission gear through the cutter head linkage 85 to obtain power. The cutter shaft assembly 86 is used to cooperate with the cutter head 8 to clamp the side wall of the container to be opened. When the electric opening device is working, the cutter shaft assembly 86 cooperates with the cutter head 8 to clamp the side wall of the container, and the driving device 6 drives the cutter shaft assembly 86 and the cutter head 8 to rotate at the same time. As the cutter shaft assembly 86 rotates, the electric opening device moves along the side wall of the container with the cutter head 8. During the movement, the cutter head 8 can cut the side wall of the container by cutting.

[0045] In addition, in some embodiments, Figure 1 and Figure 2 As shown, the power module 7 includes a rechargeable battery 71, a charging management module 72 and a voltage stabilizing module 73; wherein the charging management module 72 is connected to the charging interface and the rechargeable battery 71, and the voltage stabilizing module 73 is connected to the rechargeable battery 71 and the powered module.

[0046] The charging interface can be a USB interface, and the rechargeable battery 71 is charged by connecting a charging cable. The charging management module 72 is responsible for managing charging parameters, including charging current, etc., to ensure charging safety and charging efficiency. Optionally, the charging management module 72 can use a chip of model AP5080E as a core component, and cooperate with an auxiliary circuit to realize the corresponding function.

[0047] The voltage stabilizing module 73 is responsible for stabilizing the output voltage, specifically for outputting a stable working voltage to the main control module 4 and the attitude sensor 5. Specifically, it can be an LDO (Low Drop Out) module. LDO is a voltage stabilizing technology used to reduce the difference in input voltage and output a stable voltage. Compared with other linear voltage stabilizing devices, the LDO module has the advantages of low input voltage, low noise, and low power loss. Optionally, the voltage stabilizing module 73 can be an LDO module of model TP2083.

[0048] In addition, in practice, the electric opening device may include a main control board 11. Circuit parts such as the main control module 4, the posture sensor 5 and the power module 7 may be integrated into the main control board 11, so as to facilitate unified installation and fixing.

[0049] In addition, the housing may include an upper cover 1 and a lower cover 2. The upper cover 1 and the lower cover 2 are detachably connected by screws 9, which is convenient for disassembly and maintenance. In addition, a portion of the transmission assembly 63 is located inside the housing (connected to the motor 61), and another portion protrudes outside the lower cover 2 to provide power for the cutter head 8 outside the lower cover 2. In order to improve the sealing performance, a rubber plug 91 can also be set at the screw hole where the screw 9 is located.

[0050] A decorative piece 10 may also be provided on the outside of the housing to play a decorative and anti-slip role.
