[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] Embodiment 1

[0038] Please refer to Figures 1-14 , an embodiment provided by the present invention: an automatic quantitative feeding device for a washing machine, including a support card board 8 for connection. A stepping motor 7 is arranged near the corner of the upper end surface of the support card board 8, and a connection bottom board 1 is fixedly arranged on the lower end surface of the support card board 8. A connection shaft 4 is arranged on the upper end surface of the support card board 8 away from the connection bottom board 1. A clamping seat 11 is fixedly installed at the center of the upper end surface of the connection shaft 4. Two support card slots 5 are opened on the upper end surface of the support card board 8 near the connection shaft 4, and a positioning sliding groove 3 is opened between the two support card slots 5. A groove-shaped photoelectric switch 9 is arranged near the front of the upper end surface of the clamping seat 11, and the groove-shaped photoelectric switch 9 is used for positioning. The groove-shaped photoelectric switch 9 is in a normally closed state. When blocked, it can convert the optical signal into an electrical signal. When the light-shielding sheet 684 is displaced between the groove-shaped photoelectric switches 9, the groove-shaped photoelectric switch 9 can be activated to position the ingredients supply assembly 63 and the induction assembly 68, and at the same time, the servo motor 27 can be activated to provide enough time preparation for the lifting guide inclined plate 26.

[0039] As Figure 2 and Figure 3, a color sensor 10 is provided near the rear of the upper end face of the snap - on seat 11, and the color sensor 10 is used to identify different colors. At the center of the inner end face of the support card plate 8, a feeding device 6 is rotatably snap - connected, and both the feeding device 6 and the bottom of the stepping motor 7 are provided with arc - tooth synchronous belt pulleys 12. The two arc - tooth synchronous belt pulleys 12 are meshed and connected by an arc - tooth synchronous belt 13. The arc - tooth synchronous belt 13 can effectively improve the transmission stability and response speed, and improve the transmission stability between the stepping motor 7 and the feeding device 6.

[0040] As Figure 1 , the upper end face of the support card plate 8 is fixedly snap - connected with a feeding device 2 through support card slots 5. The two support card slots 5 can pre - provide positioning for the positioning and installation of the feeding device 2.

[0041] As Figure 7 and Figure 8 , the feeding device 2 includes a trapezoidal - tooth synchronous belt 21, a rectangular lead screw 22, a limit shaft 23, a limit slot 24, a threaded sliding sleeve 25, a guiding inclined plate 26, a servo motor 27, a connecting card plate 28, a trapezoidal - tooth synchronous belt pulley 29, a guiding chute 210, a blanking conduit 211 and a feeding pipe 212. The upper end face of the feeding pipe 212 is symmetrically and fixedly installed with blanking conduits 211 in a penetrating manner, and guiding chutes 210 are opened on the upper end faces of the two blanking conduits 211. The inside of the blanking conduit 211 and the feeding pipe 212 communicate with each other. At the same time, the inside of the feeding pipe 212 is arranged in a funnel shape, which is convenient for quickly discharging the detergent drained into the blanking conduit 211 subsequently, and improves the feeding efficiency of the detergent.

[0042] A connecting card plate 28 is fixedly arranged inside the two blanking conduits 211. A servo motor 27 is arranged near the outside of the upper end face of the connecting card plate 28, and a limit shaft 23 for guiding is fixedly installed on the upper end face of the connecting card plate 28. A rectangular lead screw 22 is rotatably snap - connected near the limit shaft 23 on the inner end face of the connecting card plate 28. Trapezoidal - tooth synchronous belt pulleys 29 are arranged on the lower end faces of both the rectangular lead screw 22 and the servo motor 27. The two trapezoidal - tooth synchronous belt pulleys 29 are meshed and connected by a trapezoidal - tooth synchronous belt 21. The outer end face of the rectangular lead screw 22 is threadedly slidably connected with a guiding inclined plate 26 through the limit shaft 23, and a limit slot 24 is opened near the high - altitude hypotenuse on the lower end face of the guiding inclined plate 26. A threaded sliding sleeve 25 is opened near the limit slot 24 on the lower end face of the limit slot 24.

[0043] As Figure 9 , Figure 10 and Figure 11, the material guiding device 6 includes a first one-way valve 61, a support turntable 62, a batching supply assembly 63, a feeding conduit 64, a feed conduit 65, a liquid level sensor 66, a storage tank body 67, an induction assembly 68, a support bearing 69 and a limit clamping shaft 610. A limit clamping shaft 610 is fixedly installed at the center of the lower end face of the support turntable 62, and a support bearing 69 for support is arranged at the outer end face of the limit clamping shaft 610 close to the support turntable 62. A storage tank body 67 is fixedly installed at the center of the upper end face of the support turntable 62, and at least six groups of induction assemblies 68 are evenly and equidistantly arranged at the upper end face of the support turntable 62 close to the outside. The upper end face of the induction assembly 68 is fixedly provided with a batching supply assembly 63, and a first one-way valve 61 is fixedly installed at the center of the upper end face of the batching supply assembly 63. The upper end face of the first one-way valve 61 is connected through the feeding conduit 64 to the inside of the storage tank body 67. Preferably, the feeding conduit 64 is of a bent structure, one end of which is introduced into the inside of the sealed tank body 631, and the other end is introduced into the inside of the storage tank body 67 close to the bottom wall, facilitating the subsequent rapid adsorption of the washing liquid.

[0044] Six groups of feed conduits 65 are evenly and equidistantly arranged at the upper end face of the storage tank body 67 close to the middle, and a liquid level sensor 66 is arranged at the upper end face of the storage tank body 67 directly opposite to the feed conduit 65. Preferably, the liquid level sensor 66 is a ceramic membrane straight rod type static pressure liquid level transmitter, which can quickly and accurately monitor the liquid level of the washing liquid inside the storage tank body 67, thereby facilitating the subsequent real-time feeding into the storage tank body 67.

[0045] As Figure 12 and Figure 13 , the batching supply assembly 63 includes a sealed tank body 631, a second one-way valve 632, a liquid guiding pipe 633, a spring snap ring 634, a sealing push plate 635, a transmission guide rod 636, a limit slider 637 and a positioning chute 638. Second one-way valves 632 are symmetrically and fixedly installed on the inner end face of the sealed tank body 631, and a liquid guiding pipe 633 is fixedly arranged at the lower end face of the two second one-way valves 632. The second one-way valve 632 is a high-pressure liquid one-way valve. When the pressure inside it is high, the second one-way valve 632 opens, and conversely, it closes when it is under negative pressure.

[0046] A sealing push plate 635 is slidably clamped on the inner end face of the sealed tank body 631, and a transmission guide rod 636 is fixedly installed at the center of the lower end face of the sealing push plate 635. The center of the lower end face of the transmission guide rod 636 is fixedly connected with a limit slider 637, and a positioning chute 638 is opened at the center of the lower end face of the limit slider 637. Fillets are arranged at the front and rear openings of the positioning chute 638, facilitating the subsequent convenient entry of the limit slider 637 into the inclined surface of the guiding bevel plate 26.

[0047] A spring snap ring 634 is fixedly installed on the inner end face top wall of the sealed tank body 631. The spring snap ring 634 can provide sufficient elastic force for the subsequent reset of the sealing push plate 635, facilitating subsequent automatic liquid level compensation.

[0048] As Figure 14 , the induction component 68 includes a fixed base 681, a positioning guide plate 682, a color label sticker 683, and a light shielding baffle 684. A positioning guide plate 682 is fixedly installed at the center of the side end face of the fixed base 681, and a light shielding baffle 684 is arranged near the front of the lower end face of the positioning guide plate 682, and a color label sticker 683 is arranged near the rear of the lower end face of the positioning guide plate 682.

[0049] As Figure 8 and Figure 12 , the inside of the guiding inclined plate 26 is arc-shaped, and the arc center of the guiding inclined plate 26 coincides with the center of the supporting clamping plate 8. When the guiding inclined plate 26 arranged in an arc shape rotates circumferentially with the batching supply component 63, its hypotenuse always fits and limits the bottom of the limiting slider 637, improving the stability of the subsequent guiding of the liquid inside the sealed tank body 631 by the limiting slider 637 driving the sealing push plate 635.

[0050] The internal opening width of the blanking conduit 211 is slightly larger than the diameter of the liquid guiding pipe 633, and the liquid guiding pipe 633 is slidably connected to the inner end face of the blanking conduit 211 through the guiding chute 210. The guiding chute 210 can provide a guiding basis for guiding the two liquid guiding pipes 633 into the blanking conduit 211. At the same time, the width of the blanking conduit 211 is larger than the diameter of the liquid guiding pipe 633, which can prevent limitation during displacement, and the two blanking conduits 211 have sufficient space to enable the liquid guiding pipe 633 to drain liquid.

[0051] The guiding inclined plate 26 is adapted to the positioning chute 3, and the guiding inclined plate 26 is slidably clamped to the inner end face of the supporting clamping plate 8 through the positioning chute 3. The width of the positioning chute 638 is slightly larger than the width of the guiding inclined plate 26, and the limiting slider 637 is slidably clamped to the outer end face of the guiding inclined plate 26 through the positioning chute 638. The positioning chute 638 can provide sufficient limiting basis for the limiting slider 637 to slide and be limited outside the guiding inclined plate 26, improving the stability of the sliding displacement of the limiting slider 637 outside the guiding inclined plate 26.

[0052] As Figure 7 , the rectangular lead screw 22 is adapted to the threaded sliding sleeve 25, and the limiting shaft 23 is adapted to the limiting groove 24. The guiding inclined plate 26 is slidably clamped to the upper end face of the connecting clamping plate 28 through the adaptation of the rectangular lead screw 22 to the threaded sliding sleeve 25 and the adaptation of the limiting shaft 23 to the limiting groove 24. The sliding fit of the limiting shaft 23 and the limiting groove 24 can radially support the guiding inclined plate 26 during lifting, and at the same time can guide the guiding inclined plate 26 axially, improving the stability of the lifting of the guiding inclined plate 26.

[0053] As Figure 14 , the light-shielding baffle 684 is directly opposite to the center of the inner end face of the groove-type photoelectric switch 9, and the upper end face of the color mark sensor 10 is coaxial with the color mark sticker 683, which facilitates the subsequent precise induction of signals by the groove-type photoelectric switch 9 and the color mark sensor 10.

[0054] As Figure 12 , the upper end face of the spring snap ring 634 is fixedly connected to the top of the sealed tank body 631, and the lower end face of the spring snap ring 634 is fixedly connected to the sealed push plate 635, which can effectively improve the stability of the subsequent elastic reset of the sealed push plate 635.

[0055] Working principle: Before use, the user can install the device on the upper part of the washing machine, so as to facilitate the subsequent rapid feeding operation inside the washing machine. Subsequently, the user can position the color mark stickers 683 of different colors at the bottom of the positioning guide plates 682 at different positions, which is convenient for subsequent control of the amounts of different detergents. At the same time, there are six different liquid storage chambers inside the storage tank body 67, which is convenient for subsequent storage and addition of different detergents, improving the adaptability of the device.

[0056] When adding detergent, the staff can start the stepping motor 7 through an external control device. At this time, the stepping motor 7 can drive the arc-tooth synchronous belt pulley 12 at the bottom to rotate, and then the arc-tooth synchronous belt pulley 12 can drive the arc-tooth synchronous belt pulley 12 located at the bottom of the feeding device 6 to rotate synchronously through the arc-tooth synchronous belt 13, and then drive the limit clamping shaft 610 to rotate circumferentially on the upper part of the support clamping plate 8. When the feeding device 6 rotates, the feeding device 6 can drive the six induction components 68 to rotate synchronously, so that the six induction components 68 can sequentially pass through the upper part of the clamping seat 11 for induction.

[0057] When the above-mentioned induction component 68 approaches the clamping seat 11 driven by the arc-tooth synchronous pulley 12, at this time, the light-shielding baffle 684 can be displaced into the groove-type photoelectric switch 9. At this time, the light signal of the groove-type photoelectric switch 9 is blocked, thereby generating an electrical signal to start the servo motor 27. At the same time, the color mark sensor 10 located on the side of the groove-type photoelectric switch 9 can synchronously identify the color mark sticker 683 opposite to it. At this time, the color mark sensor 10 can sense through the color of the color mark sticker 683, so as to control the number of rotation turns of the servo motor 27 through the encoder. When the servo motor 27 is rotating, the servo motor 27 can drive the trapezoidal-tooth synchronous pulley 29 at the bottom to rotate. At this time, the trapezoidal-tooth synchronous pulley 29 can drive the trapezoidal-tooth synchronous pulley 29 on the other side to rotate synchronously through the trapezoidal-tooth synchronous belt 21, so that the trapezoidal-tooth synchronous pulley 29 can drive the rectangular lead screw 22 to rotate synchronously. The rectangular lead screw 22 can be precisely adjusted by the threaded connection with the threaded sliding sleeve 25 to control the lifting height of the guiding inclined plate 26. When the servo motor 27 rotates a certain number of turns, the servo motor 27 stops rotating at this time, and at the same time, the guiding inclined plate 26 is lifted to a predetermined height and remains stationary. At the same time, the guiding inclined plate 26 is located above the supporting clamping plate 8.

[0058] When the guide inclined plate 26 is adjusted, the material guiding device 6 is still rotating. When the ingredient supply component 63 and the sensing component 68 are close to the feeding device 2, the liquid guide tubes 633 located on both sides of the sealed tank body 631 can slide into the material discharge conduit 211 through the guide chute 210. As the ingredient supply component 63 and the sensing component 68 continue to rotate, the limiting slider 637 at the bottom of the ingredient supply component 63 can be positioned to the guide inclined plate 26 through the positioning chute 638, so that the limiting slider 637 ... The block 637 can be slidably engaged with the bevel of the guide inclined plate 26. As the ingredient supply assembly 63 continues to rotate, the limit slider 637 moves on the bevel of the guide inclined plate 26, so that the guide inclined plate 26 can drive the rotating limit slider 637 to move upward, and then the limit slider 637 can drive the transmission guide rod 636 to lift upward, and the transmission guide rod 636 can compress the washing liquid inside the sealed tank body 631 through the sealing push plate 635, so that the inside of the sealed tank body 631 is in In the high pressure state, the first one-way valve 61 located at the top of the sealed tank body 631 is one-way closed, and the second one-way valve 632 inside the sealed tank body 631 is one-way opened, so that the washing liquid can be discharged through the liquid guide pipe 633. The liquid guide pipe 633 can guide the washing liquid discharged by the liquid guide pipe 633 into the inside of the discharge conduit 211 during the time of contact with the guide inclined plate 26, and finally guide it into the outside washing machine through the guide pipe 212. When the above-mentioned limit slider 637 is separated from the guide inclined plate 26, At this time, the spring retaining ring 634 inside the sealed tank body 631 can be elastically reset, thereby driving the sealing push plate 635 to move downward, so that the inside of the sealed tank body 631 is in a negative pressure state. At this time, the first one-way valve 61 is opened. At the same time, the first one-way valve 61 can automatically absorb and fill the same type of detergent inside the storage tank body 67 through the supply conduit 64 until the next cyclic feeding, and the cycle is repeated, which effectively improves the accuracy and efficiency of the equipment's automatic feeding inside the washing machine.
