Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figure 1 As shown, in one embodiment of this utility model, the multi-channel weighing data wireless transmission system includes a multi-channel weighing data wireless transmission control board 1. The multi-channel weighing data wireless transmission control board 1 includes a weighing bracket 2, a weighing detection module 3, a power supply module 4, an STM32F103C8T6 chip 5, and a wireless transmission module 6. The system uses Peakbird Wireless's Ling-TRL wireless transmission module as the transmission medium for weighing data. The system uses the STM32F103C8T6 control chip as the core control chip of the transmission system. The system uses the HX711 weighing detection chip as the input module for weighing detection.

[0029] like Figures 2-4 As shown, the power module 4 includes a support component, and a sealing component that matches the support component is provided on the top of the support component. A fixing component that matches the support component is fixedly connected to one side of the sealing component. The sealing component and the fixing component keep the power supply in the support component in a sealed state, avoiding the influence of the humid environment, thereby protecting the power supply.

[0030] Furthermore, the support assembly includes a base 401, on which a pair of opposite sidewalls are integrally formed with a slide rod 402. The washing machine has a pair of sliding grooves that match the slide rod 402. A pair of limiting blocks are integrally formed on the sidewalls of the slide rod 402. One sidewall of the limiting block is attached to one sidewall of the sliding groove. When the power supply needs to be replaced or repaired, the pull plate 403 can be manually pulled to slide the base 401 to the outside of the washing machine. At the same time, the slide rod 402 slides in the sliding groove on the washing machine. When one sidewall of the limiting block is attached to one sidewall of the sliding groove, the power module 4 can be slid to the outside of the washing machine without separating from the washing machine, which facilitates the replacement and repair of the power supply.

[0031] Preferably, a pull plate 403 is integrally formed on one side wall of the base 401, and a working power supply slot 404 and a spare power supply slot 405 are provided on the upper end face of the base 401. The spare power supply slot 405 is located on one side of the working power supply slot 404. The working power supply is placed in the working power supply slot 404 to connect and work with other modules. The spare power supply slot 405 can hold a spare power supply for easy replacement.

[0032] Furthermore, the sealing assembly includes a sealing plate 411, the bottom end face of which is attached to the top of the base 401. A pair of fixing blocks 410 matching the sealing plate 411 are integrally formed on the upper surface of the base 401. A pair of rotating grooves are formed on the side faces of the fixing blocks 410. A rotating column is integrally formed on the side wall of the sealing plate 411 near the fixing blocks 410. The two end side walls of the rotating column are rotatably connected to the rotating grooves on the fixing blocks 410. A sealing groove 406 is formed on the upper surface of the base 401. A sealing strip 417 matching the sealing groove 406 is fixedly connected to the bottom end face of the sealing plate 411. The outer surface of the sealing strip 417 is engaged with the inner wall of the sealing groove 406. By engaging the sealing strip 417 with the sealing groove 406, a closed structure is formed inside the base 401. When it needs to be opened, the rotating column on one side of the sealing plate 411 is used as the rotation base point, so that the two ends of the sealing plate 411 rotate into the rotating grooves of the fixing blocks 410 on the base 401.

[0033] like Figures 5-6 As shown, a pair of slots 407 are provided on the side of the working power supply slot 404 near the sealing slot 406. The fixing assembly includes an auxiliary block 412, which is fixedly connected to the bottom end face of the sealing plate 411 near the slot 407. Multiple sets of second springs 413 are fixedly connected to one side wall of the auxiliary block 412. A locking block 415 is fixedly connected to one side of the multiple sets of second springs 413. A limiting groove 414 is provided on one side wall of the auxiliary block 412. A sliding block 416 is integrally formed on the top end face of the locking block 415. The outer wall of the sliding block 416 is slidably connected to the inner wall of the limiting groove 414. The outer walls of the auxiliary block 412 and the locking block 415 are engaged with the inner wall of the slot 407. A first spring 408 is fixedly connected to one side inner wall of the slot 407. A pressing block 409 is fixedly connected to the other side wall of the first spring 408. A pair of opposing outer walls of the pressing block 409 are fixedly connected to the first spring 408. The sliding block 412 is connected to a pair of inner walls of the slot 407. To enhance the stability of the seal, when the sealing strip 417 is engaged in the sealing groove 406, the auxiliary block 412 drives the locking block 415 to move into the slot 407. When the locking block 415 contacts one inner wall of the slot 407 on the base 401, it is pushed by the inner wall and moves towards one side of the second spring 413. At the same time, the sliding block 416 slides in the limiting groove 414 and drives the second spring 413 to compress, so that one side wall of the locking block 415 and one side wall of the auxiliary block 412 are in a straight line. When the bottom end face of the auxiliary block 412 and the locking block 415 moves to fit the bottom end face of the slot 407, the second spring 413 automatically rebounds. At this time, the top end face of the locking block 415 fits against one inner wall of the slot 407, and the auxiliary block 412 and the locking block 415 are stably engaged in the slot 407.

[0034] Furthermore, when it is necessary to open the sealing plate 411, the auxiliary block 412 and the locking block 415 need to be moved away from the slot 407. At this time, the operator drives the pressing block 409 to press towards the side closer to the locking block 415. At this time, the pair of side walls of 419 slide into the slot 407 and enter the pair of side walls of the pressing block 409. While moving inward, the first spring 408 is compressed, and the locking block 415 is moved towards the side closer to the auxiliary block 412. This makes the side wall of the locking block 415 close to the pressing block 409 and the side wall of the auxiliary block 412 close to the pressing block 409 keep in a straight line. Then, one side of the sealing plate 411 is pulled upward, which moves the auxiliary block 412 and the locking block 415 away from the slot 407. At this time, the sealing plate 411 is in the open state.

[0035] When using, such as Figures 2-3 As shown, the working power supply and the backup power supply are placed in the base 401, so that the sealing strip 417 in the sealing assembly is engaged in the sealing groove 406, and the auxiliary block 412 and the locking block 415 in the fixing assembly are engaged in the locking groove 407. The resulting sealing structure ensures the stability of the power supply during operation.

[0036] like Figure 1 As shown, when the power supply needs to be replaced, pull the lever 403 to slide the power module 4 completely away from the washing machine. Then operate a pair of fixing components, rotate the sealing component, and move the fixing component away from the slot 407. After the sealing plate 411 is in the open state, the internal power supply can be replaced or repaired.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
