A microphone 207 is fixedly mounted on the top of the folding frame 206. The microphone 207 interacts with the voice through Bluetooth. The external voice interactive device 201 is used as the functional carrier of voice interaction, which is convenient for replacement and repair. The microphone 207 is used as the front end of voice reception, which can effectively receive voices in the corresponding direction, reducing the processing volume and difficulty of the voice interactive device 201. The mounting plate 204 is stored through the storage slot 202, and then the folding frame 206 and the microphone 207 are stored, that is, the microphone 207 and other structures are stored when not in use. The mounting plate 204 is limited by the slide slot 203 and the slide plate 205 to prevent the mounting plate 204 from being separated from the storage slot 202;

[0033] A cleaning module 3 is fixedly installed on the electronic scale body 1 to clean the scale body on the electronic scale body 1 to prevent debris from falling on the scale body and causing obvious weighing errors. A transfer module 4 is fixedly arranged at the bottom of the electronic scale body 1 to assist the user in transferring the electronic scale body 1.

[0034] The folding frame 206 includes a storage frame 2061, which is hinged to the mounting plate 204 through a pin shaft. The top of the storage frame 2061 is hinged to a rotating plate 1 2062 through a pin shaft. The end of the rotating plate 1 2062 away from the storage frame 2061 is hinged to a rotating plate 3 2063 through a pin shaft. The rotating direction of the rotating plate 3 2063 is perpendicular to the rotating direction of the rotating plate 1 2062. The microphone 207 is fixedly mounted on the end of the rotating plate 3 2063 away from the rotating plate 1 2062. The storage frame 2061 is hinged to the mounting plate 204 to perform a primary angle adjustment. At the same time, the inner space of the storage frame 2061 is used to store the rotating plate 1 2062, the rotating plate 3 2063, and the microphone 207. The vertical rotating directions of the rotating plates 1 2062 and 3 2063 are used to adjust the microphone 207 at multiple angles.

[0035] The outer walls of the pins of the storage rack 2061 and the mounting plate 204, the pins of the storage rack 2061 and the rotating plate 1 2062, and the pins of the rotating plate 1 2062 and the rotating plate 3 2063 are all threadedly sleeved with nuts 7, and compression pads 8 are arranged between the nuts 7 and the storage rack 2061 and the rotating plate 1 2062.

The storage rack 2061 and the rotating plate 1 206 are supported by the nuts 7 and the compression pads 8. 2. The rotating plate 3 2063 is pressed so that the storage rack 2061, the rotating plate 1 2062, and the rotating plate 3 2063 have a damping feeling when they rotate. At the same time, after adjusting the angle of the microphone 207, the storage rack 2061, the rotating plate 1 2062, and the rotating plate 3 2063 will not rotate under gravity to cause the angle of the microphone 207 to change. The avoidance gap 6 is set to avoid the microphone 207, ensuring that the rotating plate 1 2062, the rotating plate 3 2063, and the microphone 207 can be stored in the storage rack 2061;

[0036] The cleaning module 3 includes a mounting groove 301, which is provided at the bottom of the electronic scale body 1. A micro air pump 302 is installed inside the mounting groove 301. A connecting pipe 303 is provided at the output end of the micro air pump 302. A U-shaped blowing head 304 is provided at the top of the connecting pipe 303. The U-shaped blowing head 304 is fixedly installed at the top of the electronic scale body 1. A high-speed airflow is generated by the micro air pump 302. The airflow enters the connecting pipe 303 from the micro air pump 302, and then enters the U-shaped blowing head 304. The airflow is blown toward the scale body from the U-shaped blowing head 304 to blow away the debris remaining on the scale body.

[0037] The inner wall of the opening of the U-shaped blowing head 304 is fixedly installed with an air guide plate 10 and an air guide plate 2 11. The air guide plate 10 is inclined to the right, and the air guide plate 2 11 is inclined downward. The air guide plate 10 and the air guide plate 2 11 are arranged to guide the airflow blown out of the U-shaped blowing head 304 to ensure that the airflow can blow away the debris on the scale body;

[0038] A shock-absorbing pad 9 is provided between the micro air pump 302 and the mounting groove 301 to prevent the vibration generated by the micro air pump 302 when working from causing adverse effects on the electronic scale body 1. The height of the opening on the U-shaped blower head 304 is greater than the height of the top scale body of the electronic scale body 1.

[0039] The transport module 4 includes a mounting frame 401, which is fixedly mounted on the bottom of the electronic scale body 1. The inner wall of the mounting frame 401 is rotatably connected with a U-shaped rod 402 through a bearing, and a handle 405 is fixedly mounted on the end of the shorter side of the U-shaped rod 402. A fixing plate 403 is fixedly mounted on the outer wall of the U-shaped rod 402, and a torsion spring 404 is arranged between the fixing plate 403 and the mounting frame 401. When transporting, the electronic scale body 1 can be inverted, and then the U-shaped rod 402 is rotated to extend the handle 405 from the mounting frame 401, and then the entire scale can be transported by holding the handle 405. Compared with directly holding the electronic scale body 1, this method is simpler to hold and more convenient to carry. The fixing plate 403 and the torsion spring 404 are arranged to drive the U-shaped rod 402 to reset, and then drive the handle 405 back to the inner side of the mounting frame 401;

[0040] Two U-shaped rods 402 are provided and symmetrically arranged on the inner side of the mounting frame 401. The outer wall of the U-shaped rod 402 is provided with a holder 12, and the holder 12 is fixedly installed on the bottom of the electronic scale body 1. Two grips 405 are provided so that two hands can hold it at the same time to improve the stability during transportation;

[0041] Shock-absorbing seats 5 are fixedly installed at the four corners of the bottom of the electronic scale body 1. The lower surface of the shock-absorbing seats 5 is higher than the lower surface of the installation frame 401, so as to support and dampen the electronic scale body 1.

[0042] There are two storage slots 202, mounting plates 204, folding frames 206, and microphones 207, which are symmetrically distributed front and back about the electronic scale body 1, for increasing the range of voice reception. While increasing the range, the two microphones 207 can also ensure the accuracy of voice reception.

[0043] Working principle: When in use, when voice interaction is required, pull the folding frame 206 on the mounting plate 204 out of the storage slot 202, then rotate the storage frame 2061, the rotating plate 1 2062, and the rotating plate 3 2063 to adjust the angle of the microphone 207 so that the microphone 207 faces the user. The user speaks a control command, and the microphone 207 receives the voice and sends it to the voice interactive device 201. The voice interactive device 201 recognizes it and then interacts. After a weighing, the micro air pump 302 is turned on to generate a high-speed airflow, and the airflow is from the micro air pump 302 to the micro air pump 302. The air pump 302 enters into the connecting pipe 303, and then enters into the U-shaped blowing head 304, and blows toward the scale body from the U-shaped blowing head 304 to blow away the debris remaining on the scale body. When the electronic scale body 1 needs to be transported, the electronic scale body 1 is turned upside down, and then the handle 405 is held to transport the entire scale. After the transportation is completed, the handle 405 is released. At this time, the torsion spring 404 drives the fixed plate 403 to rotate, and then drives the U-shaped rod 402 to reset, so that the handle 405 returns to the inner side of the installation frame 401, so that the electronic scale body 1 can be stably placed on a plane.

[0044] In another embodiment, if Figure 7 As shown, based on the embodiment, the cleaning module 3 also includes a groove 305 opened on the upper end surface of the electronic scale body 1, and a box body 13 and an air guide cover 14 are arranged in the groove 305. A lifter is also arranged in the box body 13, and one end of the lifter is fixedly connected to the box body 13, and the other end is fixedly connected to the air guide cover 14, so that the micro air pump can open the air guide cover to collect dust while cleaning the dust.

[0045] Continue to refer to Figure 8 The air guide cover 14 can be stored in the box body 13 by using a lifter, and the lifter is driven by a micro air pump 302. Since the air guide plate 10 is tilted to the right and the air guide plate 2 11 is tilted downward, the dust can be blown to the side of the air guide cover 14 through the air guide plates 10 and 11. When the lifter is at the maximum lift, the height of the top of the air guide cover 14 is greater than the height of the top of the electronic scale body 1, thereby ensuring that the dust can be blown into the air guide cover 14.

[0046] Furthermore, the box body 13 and the air guide cover 14 are slidably connected in the vertical direction. The side of the box body 13 is L-shaped and a handle 1301 is left at the top of the box body 13. The lifter selects a pneumatic rod 306. The air inlet and exhaust ports of the pneumatic rod 306 are connected to air pipes 307. The side of the air guide cover 14 is provided with an air nozzle 308. The outer end of the air nozzle 308 is connected to the micro air pump 302 through another connecting pipe, and the inner end of the air nozzle 308 is connected to the two air pipes 307 through a reversing solenoid valve. The reversing solenoid valve can be a three-position two-way solenoid valve. At this time, a micro PLC compatible with the three-position two-way solenoid valve can also be provided in the box body 13 to control the three-position two-way solenoid valve to realize the rise and fall of the pneumatic rod 306. Then, when the cleaning module 3 starts to work, the pneumatic rod 306 rises, and the dust is introduced into the box body 13 by lifting the guide cover. The box body 13 can be taken out by the handle 1301 for dust treatment.

[0047] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
