Description

Technical Field

[0001] The present invention relates to the technical field of clothing additive delivery, and in particular to an intelligent recognition component, an additive delivery device and an identification method. Background Art

[0002] Washing machine dispensers are becoming increasingly popular, but existing ones only meet simple user needs and fall far short of the high-tech standards of intelligent dispensing. Existing additive dispensers typically have multiple mounting locations, each for a separate reservoir. This allows reservoirs storing different types of additives to be simultaneously mounted on the same additive dispenser, enabling the dispenser to selectively dispense different additives, or in combination.

[0003] As the functions of washing machines increase, washing machines can automatically dispense detergents, stain removers, color protectants, softeners and other clothing treatment agents. The types of liquid storage boxes have become more complex and diverse, making it difficult for users to determine whether the installation positions of each liquid storage box are accurate, and it is very easy to make mistakes in the dosage of additives.

[0004] The invention patent with application number 201810617547.4 discloses a control method and device for automatically dispensing multiple clothing treatment agents into a washing machine. The automatic dispensing device includes a fixed-type treatment agent box for holding a fixed type of clothing treatment agent and a variable-type treatment agent box for selectively holding one type / multiple types of clothing treatment agents at the same time; the control method includes: the washing machine executes a washing program, and the automatic dispensing device executes the corresponding dispensing process according to the clothing treatment agent selected in the fixed-type treatment agent box and / or the variable-type treatment agent box.

[0005] While the automatic dispensing device disclosed in the aforementioned application can achieve the purpose of targeted intelligent dispensing for different garments by providing a selectable variable-type treatment agent box and controlling the dispensing of the clothing treatment agent in the variable-type treatment agent box, the disclosed dispensing device cannot automatically identify the type of additive stored in the variable-type treatment agent box, making it impossible to accurately dispense the additive based on the actual type in the subsequent washing process.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0074] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0075] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0076] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0077] The present invention will be further described in detail below with reference to the embodiments.

[0078] like Figures 1 to 10As shown, an embodiment of the present invention provides an intelligent recognition component, an additive dispensing device, and an identification method. The additive dispensing device 7 provided by the present invention allows the user to randomly place different types of liquid storage boxes 6 into any of the bins in the additive dispensing device 7; there is no need to match them to the designated bins, and after placing them, the user can directly select the program and start washing. The intelligent recognition component 1 in the automatic dispensing device 7 can intelligently identify the type of additive stored in the liquid storage box 6 in each bin and feed it back to the control unit of the additive dispensing device 7. The control unit then controls the timing of dispensing the additives in the liquid storage boxes 6 in each accommodating portion according to the washing program.

[0079] Example 1

[0080] like Figures 1 to 9 As shown, this embodiment provides an intelligent identification component 1, including:

[0081] The contact switch 2 includes a correspondingly arranged connection terminal 22 and a conductive spring 21 that can be connected or disconnected. In an initial state, the conductive spring 21 and the connection terminal 22 are in a disconnected state;

[0082] The swing trigger 3 is swingably disposed on the side of the contact switch 2 near the conductive spring 21. When the swing trigger 3 is swung by an external force, it pushes the conductive spring 21 into contact with the terminal 22. The conductive spring 21 and the terminal 22 come into contact with each other under the push of the swing trigger 3, achieving electrical conduction.

[0083] like Figures 5 to 9 As shown, the intelligent identification component 1 provided in this embodiment uses a swinging trigger member 3 to push the conductive spring 21 to contact the terminal 22, so as to trigger the contact switch 2 to send an identification signal of conduction. The swinging trigger member 3 serves as an intermediate member for transmitting the driving force, which can not only effectively trigger the conductive spring 21 to connect with the terminal 22, but also has a simple structure and is easy to implement.

[0084] In the above scheme, the connecting terminal 22 and the conductive spring 21 can be arranged correspondingly up and down, the missile spring is arranged below the connecting terminal 22, and the swing trigger member 3 can be set below the conductive spring 21 so as to swing up and down. When the swing trigger member 3 swings upward under the action of external force, it pushes the conductive spring 21 to move upward and contact with the connecting terminal 22 to be conductive, thereby triggering the contact switch 2 to send a detection signal of conduction.

[0085] Of course, the connecting terminal 22 and the conductive spring 21 can also be arranged in correspondence with each other on the left and right sides. The missile spring is arranged on the left or right side of the connecting terminal 22 at a certain distance, and the swing trigger 3 can be set on the left or right side of the conductive spring 21 so as to swing left and right. When the swing trigger 3 swings left or right under the action of external force, it pushes the conductive spring 21 to move left or right and contact and conduct with the connecting terminal 22, thereby triggering the contact switch 2 to send a detection signal of conduction.

[0086] Preferably, if Figure 2 and Figure 7 、 Figure 9 As shown, in this embodiment, the connection terminal 22 and the conductive spring 21 are arranged in a corresponding vertical arrangement. The missile spring is disposed below the connection terminal 22, and the swing trigger 3 is disposed below the conductive spring 21 so as to swing upward and downward. When not subject to external forces, the swing trigger 3 freely hangs downward under the action of gravity. When subjected to external forces, it swings upward, pushing the conductive spring 21 upward to contact and conduct with the connection terminal 22. By adopting this design, the swing trigger 3 can automatically reset itself by means of gravity, eliminating the need for a reset mechanism, resulting in a simpler structure and lower cost for the entire intelligent identification component 1.

[0087] Furthermore, in this embodiment, the intelligent identification component 1 includes a plurality of groups of the contact switches 2 , and there are a plurality of swing triggering members 3 , which are arranged in a one-to-one correspondence with the contact switches 2 .

[0088] When the swing trigger members 3 at different positions and / or numbers swing under the action of external force, the conductive springs 21 at corresponding positions and / or corresponding numbers are pushed to contact and connect with the terminal 22, so that the intelligent identification component 1 can output detection signals of different combinations.

[0089] Furthermore, if Figures 1 to 3 、 Figures 5 to 7 As shown, the intelligent identification component 1 further includes a mounting shell 4, and the mounting shell 4 includes:

[0090] An upper housing 41, wherein the contact switch 2 is disposed in the upper housing 41, wherein the upper housing 41 has a mounting cavity with an open lower end, and the contact switch 2 is disposed in the mounting cavity;

[0091] A lower cover plate 42 is provided to seal the lower opening of the upper housing 41 , and the swing trigger member 3 is mounted below the lower cover plate 42 so as to be able to swing up and down;

[0092] The swing trigger member 3 includes a swing rod with one end rotatably connected to the bottom of the lower cover 42 and the other end capable of pushing the conductive spring 21 to move upward to contact and connect with the wiring terminal 22 .

[0093] Preferably, the end of the swing arm that contacts the conductive spring 21 is provided with an upwardly protruding spring push portion 32, and a clearance hole 424 is provided on the lower cover 42 at a position corresponding to the spring push portion 32. When the swing arm swings upward, the spring push portion 32 extends through the clearance hole 424 into the upper housing 41, pushing the conductive spring 21 upward, thereby contacting and connecting the conductive spring 21 with the terminal 22. The provision of the clearance hole 424 effectively prevents the lower cover 42 from obstructing the swing arm's upward movement, thereby pushing the conductive spring 21 into normal contact and connection with the terminal 22.

[0094] Better, if Figure 2 、 Figure 7 、 Figure 9 As shown, the spring pushing portion 32 is a pushing column connected to the rocker at an angle of not less than 90°. Further preferably, the pushing column is connected to the rocker at an angle of 90°-120°. Further preferably, in this embodiment, the pushing column is connected to the rocker at an angle of 90°. In this embodiment, the pushing column has a certain extension length and is connected to the rocker at an angle of 90°-120°, so that when the rocker moves upward, the pushing column can smoothly extend into the shell through the avoidance hole 424 to push the conductive spring 21 upward without causing interference with the avoidance hole 424.

[0095] In this embodiment, the ejection column and the rocker arm are integrally formed by melting and / or injection molding and / or bonding.

[0096] Furthermore, the rocker arm includes a rocker arm body 31 and a rocker arm pushing portion 33 for assisting in pushing the rocker arm upward. The rocker arm body 31 is a rod-shaped structure with a certain extension length. The extension direction of the rocker arm body 31 is parallel to the insertion direction of the liquid storage box 6 into the additive dosing device 7.

[0097] like Figure 2 、 Figures 5 to 9 As shown, the rocker arm pushing portion 33 is a raised structure arranged below the rocker arm body 31. After the liquid storage box 6 is inserted into the accommodating portion of the additive delivery device 7, the concave-convex portion 61 provided on the liquid storage box 6 for identifying the type of additive stored in the liquid storage box 6 presses against the raised structure below the swing trigger member 3 at the corresponding position, pushing the rocker arm to move upward and pushing the conductive spring 21 to contact and connect with the wiring terminal 22.

[0098] Preferably, if Figure 6 、 Figure 7 、 Figure 9As shown, the raised structure is a plate-like rib connected to the bottom of the rocker body 31, and the plate-like rib is a triangular plate-like structure. The plate-like rib includes an inclined guide wall 331 that is gradually inclined downward from the rocker close to the rotating end side toward the spring pushing top part 32; the inclined guide wall 331 plays a certain guiding role, so that after the liquid storage box 6 is inserted into the accommodating part, the concave and convex part 61 on the liquid storage box 6 can more smoothly abut against the plate-like rib, pressing the rocker upward.

[0099] More preferably, the plate-shaped rib is disposed on the rocker body 31 between the pivoting end of the rocker and the spring-loaded push portion 32, and the plate-shaped rib is disposed on the rocker body 31 near the spring-loaded push portion 32. This design allows for even slight changes in the position of the plate-shaped rib to amplify the displacement of the spring-loaded push portion 32 several times, thereby enabling more accurate and efficient detection and identification of the type of additive stored in the liquid storage box 6.

[0100] Furthermore, if Figure 6 and Figure 7 As shown, the rocker arm also includes a rocker arm limiter 34 for limiting the downward displacement of the rocker arm; the rocker arm limiter 34 can effectively prevent the rocker arm from being displaced too long downward, thereby preventing interference with the normal pulling of the liquid storage box 6.

[0101] Preferably, if Figure 7 As shown, the rocker arm limiter 34 is a limiter segment formed by a protruding extension from the end of the rocker arm body 31 on the side where the rotating shaft hole 351 is located. A corresponding limiter step 429 is provided on the lower cover plate 42 to engage with the limiter segment. The limiter step 429 has a limiter top wall that restricts the upward movement of the limiter segment. The limiter step 429 is composed of a limiter top wall and limiter side walls connected at a 90-degree angle. When the rocker arm swings downward, the limiter top wall abuts against the limiter segment, preventing the other end of the rocker arm, which is provided with the spring-loaded push portion, from further downward rotation and maintaining the limiter at the set initial position.

[0102] When the swing arm is in the initial position, the swing arm is tilted downward, and the spring pushing portion 32 and the conductive spring 21 are separated and not in contact. When squeezed by the concave-convex portion 61 on the liquid storage box 6, the swing arm rotates upward to the trigger position. At the trigger position, the spring pushing portion 32 contacts the conductive spring 21 and pushes the conductive spring 21 to move upward, so that the conductive spring 21 contacts the terminal 22.

[0103] Better, if Figure 7As shown, the rocker arm is provided with a connecting ear 35 above it. This connecting ear 35 is a semicircular structure with an arc-shaped outer wall, integrally formed with the rocker arm. The pivot hole 351 is provided in this connecting ear 35, and the lower cover plate 42 is provided with an arc-shaped avoidance groove 421 to prevent the connecting ear 35 from rotating. This arc-shaped avoidance groove 421 allows the rocker arm to avoid the connecting ear 35 during swinging. It also serves as a position limiter, preventing the rocker arm from shifting. The arc-shaped avoidance groove 421 connects to the top limit wall of the limit step 429. When the connecting ear 35 of the rocker arm rotates along the arc-shaped avoidance groove 421, the limit section at the end of the rocker arm will limit the top limit wall of the limit step 429, preventing it from falling below its initial position during free downward movement.

[0104] Furthermore, if Figure 6 As shown, a plurality of strip-shaped protrusions 422 are provided on the bottom wall of the lower cover plate 42, and a spacing space for accommodating the rocker arm is formed between two adjacent protrusions; the extension direction of the strip-shaped protrusions 422 is parallel to the extension direction of the rocker arm, and the rocker arm is limited to the spacing space between the two strip-shaped protrusions 422 to prevent the rocker arm from moving on the lower cover plate 42 and affecting the normal recognition and detection of the intelligent recognition component 1.

[0105] A first rotating shaft is provided on the protrusion, and a rotating shaft hole 351 is provided on the end of the rocker arm away from the spring pushing part 32. The rocker arm is rotatably mounted on the lower cover plate 42 through the rotating shaft hole 351 and the first rotating shaft; the first rotating shaft is fixedly connected between two adjacent protrusions, and the rocker arm is rotatably connected to the first rotating shaft.

[0106] Preferably, if Figures 6 to 9 As shown, the circumferential edge of the lower cover plate 42 is folded downward to form a flange structure 423, the protrusions are arranged at intervals along the width direction of the lower cover plate 42, a second rotating shaft is provided between the flange structure 423 and the protrusions, and the rocker arm is rotatably mounted on the first rotating shaft and / or the second rotating shaft.

[0107] By providing the flange structure 423 on the lower cover 42, on the one hand, a mounting cavity is formed for installing the swing trigger member 3. The swing trigger member 3 is installed in the mounting cavity formed by the lower cover 42 and the flange structure 423, which provides a certain degree of protection for the swing trigger member 3. At the same time, the swing trigger member 3 cannot be seen from the outside, thereby improving the aesthetics. On the other hand, a second rotating shaft can be provided between the flange structure 423 and the protrusion for installing the swing arm, so that the space below the lower cover 42 can be more reasonably utilized.

[0108] Furthermore, if Figures 7 to 9As shown, the intelligent identification assembly 1 further includes a waterproof pad 5 disposed between the lower cover 42 and the conductive spring 21, the waterproof pad 5 at least shielding the area above the avoidance hole 424. Because the additive dispensing device 7 is exposed to high temperature, high humidity, and a high concentration of impurities, the provision of the waterproof pad 5 effectively prevents problems such as condensed water and contaminants in the accommodating chamber from directly contacting the conductive spring 21, leading to accidental contact.

[0109] Preferably, if Figure 7 As shown, the waterproof pad 5 is a flexible rubber membrane that covers the entire lower cover plate 42. It includes a flexible, retractable sleeve 51 that blocks the escape hole 424. The retractable sleeve 51 is a closed, bellows-shaped sleeve that can be extended and retracted vertically. The retractable sleeve 51, which blocks the escape hole 424, ensures a watertight seal while preventing interference with the spring pusher 32's ability to push the conductive spring 21.

[0110] Preferably, the waterproof pad 5 includes a waterproof pad body covering the upper surface of the lower cover plate 42. The flexible expansion sleeve 51 is provided on the waterproof pad body at a position corresponding to the avoidance hole 424. The flexible expansion sleeve 51 is a flexible rubber membrane structure having multiple folds. The folds, which are either upwardly protruding or downwardly recessed, enhance the expansion and contraction performance of the flexible expansion sleeve 51, enabling it to push the conductive spring 21 upward as the spring pusher portion 32 moves upward. The waterproof pad 5 is provided with a deformable flexible expansion sleeve 51 that contacts the spring pusher portion 32. The deformable flexible expansion sleeve 51 can expand and contract upward with the spring pusher portion 32, transmitting the pressing action of the rocker arm 31 and triggering the contact switch 2 to turn on.

[0111] Better, if Figure 7 As shown, the flexible rubber membrane is provided with an upwardly protruding boss structure 52 in the middle thereof. Above the boss structure 52 is a push-up surface that engages and contacts the conductive spring 21. When the swing arm swings upward, the spring push-up portion 32 extends through the avoidance hole 424 into the flexible telescopic sleeve 51, pushing the flexible telescopic sleeve 51 upward, thereby pushing the conductive spring 21 upward. The boss structure 52 allows the spring push-up portion 32 to more easily contact the conductive spring 21 when pushing the flexible telescopic sleeve 51.

[0112] In the above solution, when the swing trigger member 3 swings upward, it drives the spring pusher 32 to press against the flexible telescopic sleeve 51, causing the flexible telescopic sleeve 51 to deform. The swing trigger member 3, through the protruding structure of the flexible telescopic sleeve 51, presses the voltage-conducting spring 21 to close the contact switch 2. In this way, the flexible telescopic sleeve 51 transmits its movement, closing the contact switch 2 and completely isolating the high temperature, high humidity, and impurities inside the accommodating portion 71 of the additive dispensing device 7 from affecting the contact switch 2.

[0113] In this embodiment, the waterproof pad 5 is made of rubber material as a whole, which not only has good water-proof effect and low cost, but also has certain elasticity. The waterproof pad 5 body can be fixed on the top of the lower cover plate 42 by bonding, clamping or connecting parts.

[0114] Since the intelligent recognition component 1 is mounted on the mounting opening 721 provided on the integrated waterway of the additive dosing device 7, the intelligent recognition component 1 is in direct contact with the liquid storage box 6. The environment of the additive dosing device 7 is high temperature and high humidity, and there are also certain impurities. Condensed water and pollutants directly contacting the conductive spring 21 may cause problems such as miscontact. To solve this problem, the present embodiment provides the above-mentioned flexible rubber membrane mounted on the lower cover 42, which can effectively prevent water, dust and other pollutants from contaminating the conductive spring 21 and affecting the normal recognition and detection effect of the intelligent recognition component 1, thereby improving the sensitivity and recognition efficiency of the intelligent recognition component 1.

[0115] Furthermore, if Figure 2 、 Figures 7 to 9 As shown, the conductive spring 21 is a long strip-shaped spring structure. In one embodiment, one end of the conductive spring 21 is a fixed end, and the other end is a free end.

[0116] The connection terminal 22 includes:

[0117] a first terminal electrically connected to the fixed end of the spring structure;

[0118] The second terminal is correspondingly arranged above the free end of the conductive spring 21 . The free end of the spring structure can be in contact with or separated from the second terminal under the push of the swing trigger 3 .

[0119] Preferably, if Figures 7 to 9 As shown, the device further includes a PCB board 23 fixedly mounted above the lower cover 42. The first and second terminals are conductive contacts integrated into the PCB board 23. The fixed end of the conductive spring 21 is connected to the first terminal and can be welded to the PCB board 23. The free end of the conductive spring 21 can move upward under the push of the swing trigger 3 to contact or separate from the second terminal.

[0120] The lower cover 42 is provided with a limiting support plate 427 for supporting and fixing the PCB board 23. The limiting support plate 427 is fixedly set on the upper surface of the lower cover 42 and distributed at the front and rear ends of the lower cover 42 to provide a more balanced and stable supporting force for the PCB board 23.

[0121] like Figures 7 to 9 As shown, the top of the limiting support plate 427 has a support surface that supports the lower surface of the PCB board 23. Preferably, the limiting support plate 427 is provided with an upwardly protruding limiting post 4271. The PCB board 23 is provided with a corresponding limiting hole, and the limiting post 4271 passes through the limiting hole of the PCB board 23. The limiting post 4271 cooperates with the limiting hole to limit and fix the PCB board 23 in the circumferential direction, preventing the PCB board 23 from shifting or moving in the horizontal direction.

[0122] Preferably, the top of the limiting column 4271 is provided with an annular boss to clamp the PCB board 23 on the limiting support plate 427. Alternatively, the limiting column 4271 is provided with an external thread to fix the PCB board 23 on the limiting support plate 427 through a nut.

[0123] Or, as Figure 7 As shown, the upper housing 41 is provided with a plurality of downwardly extending vertical limit rods, the lower ends of which extend to the upper surface of the PCB board 23, and can abut against the upper surface of the PCB board 23 or have a small gap therebetween. The upper end of the limit support plate 427 supports the lower surface of the PCB board 23, and the PCB board 23 is clamped and fixed between the limit support plate 427 and the vertical limit rods.

[0124] This embodiment provides another arrangement of the conductive spring 21 and the terminal 22 . Different from the above embodiment, the conductive spring 21 is freely arranged below the PCB board 23 , and both ends are not fixed.

[0125] Specifically, the conductive spring 21 is movably arranged below the PCB board 23, and at least one vertical guide rod is provided on the conductive spring 21. The PCB board 23 is provided with a guide hole, and the vertical guide rod is movably arranged in the guide hole.

[0126] In its natural state, the conductive spring 21 is supported and fixed above the limiting support plate 427 under the action of gravity. The conductive spring 21 has no substantial connection with the limiting support plate 427 or the PCB board 23. The conductive spring 21 is provided with a limiting hole that cooperates with the limiting post 4271 on the limiting support plate 427. The limiting post 4271 passes through the limiting holes on the conductive spring 21 and the PCB board 23 in sequence, limiting the conductive spring 21 and the PCB board 23 in the circumferential direction. The PCB board 23 is provided with a first terminal and a second terminal at intervals. The conductive spring 21 moves upward as a whole under the thrust of the swinging force, contacts the first terminal and the second terminal, respectively, and conducts the circuit between the first terminal and the second terminal.

The upper shell 41 and lower cover 42 are connected and fixed by a snap-fit ​​connection, and the assembly and disassembly of the upper shell 41 and the lower cover 42 can be achieved without the aid of other connecting parts.

[0128] Preferably, in this embodiment, Figure 5 As shown, the upper shell 41 and the lower cover 42 are engaged with each other using a snap-fitting mechanism of a slot 4121 and a latch 426. A downwardly extending extension plate 412 is provided on the peripheral wall of the upper shell 41.

When the upper shell 41 and the lower cover 42 are closed, the extension plate 412 extends into the retaining groove 425, and the latch 426 is engaged with the slot 4121 of the extension plate 412. The snap-fitting mechanism of the slot 4121 and the latch 426 between the upper shell 41 and the lower cover 42 provides greater stability.

[0129] Furthermore, if Figure 5 As shown, the extension plate 412 and the limiting groove 425, the clamping slot 4121 and the clamping platform 426 are respectively provided on the two opposite side walls of the mounting shell 4. Preferably, a positioning structure for assisting the positioning of the upper shell 41 and the lower cover 42 is provided on at least one of the front and rear side walls of the mounting shell 4.

[0131] like Figures 1 to 10 As shown, this embodiment introduces a liquid storage box 6, which has a sealed chamber for storing additives, such as Figure 10 As shown, at least one concave-convex portion 61 is provided on the outer wall of the liquid storage box 6 , and the number and position combination of the concave-convex portions 61 provided on the liquid storage box 6 corresponds to the type of additive stored in the liquid storage box 6 .

[0132] By providing at least one concave-convex portion 61 exposed on the outer wall of the liquid storage box 6, the type of additive contained in the liquid storage box 6 is accurately identified by utilizing any one or a combination of information such as the number, relative position, and location of the concave-convex portion 61 on the liquid storage box 6, thereby achieving a significant technical advancement in clearly identifying the category information of additives for different liquid storage boxes 6.

[0133] In an embodiment of the present invention, there can be multiple types of liquid storage boxes 6, and various liquid storage boxes 6 are used to respectively hold different types of additives; the liquid storage boxes 6 for storing different types of additives are provided with different numbers, positions or combinations of different concave and convex parts 61. In an embodiment of the present invention, the types of additives include the following: detergents, fragrance enhancers, softeners, disinfectants, etc., so that different types of additives can be added separately or in combination, so that when the clothing processing device executes different types of programs, different types of additives are used to treat the clothes accordingly. At the same time, in an embodiment of the present invention, each liquid storage box 6 installed on the additive delivery device 7 can also store detergents of different concentrations, such as: super concentrated, concentrated, ordinary, low foam, etc., so that when the clothing processing device executes different washing programs, corresponding types of detergents can be added to achieve corresponding washing of different clothes, thereby achieving the purpose of improving the washing effect of the clothing processing device.

[0134] In the first embodiment

[0135] like Figures 1 to 4 and Figure 10As shown, the positions of the concave and convex parts 61 provided on the liquid storage box 6 in this embodiment correspond to the types of additives stored in the liquid storage box 6. In this embodiment, the outer wall of the liquid storage box 6 for storing different types of additives is provided with concave and convex parts 61 at different positions.

[0136] In this embodiment, the concave-convex portion 61 is a protrusion protruding outward from the outer wall of the liquid storage box 6. In this embodiment, for ease of description in the drawings, the concave-convex portion 61 is illustrated as a protrusion protruding outward from the outer wall of the liquid storage box 6.

[0137] In this embodiment, the concave-convex portion 61 can be integrally formed with the liquid reservoir 6 and formed directly from the outer wall of the liquid reservoir 6; alternatively, the concave-convex portion 61 and the liquid reservoir 6 have different structures and are formed by independent components mounted on the outer wall of the liquid reservoir 6. In this embodiment, the concave-convex portion 61 can be made of any material, as long as the concave-convex portion 61 is in contact with the swing trigger 3 of the smart identification component 1, the protrusion will press the swing trigger 3, causing the contact switch 2 to generate a trigger signal.

[0138] Preferably, in this embodiment, in order to further improve the accuracy of the concave-convex portion 61 when acting on the contact switch 2, the following settings can be made: at least part of the outer wall of the liquid storage box 6 is a smooth surface, and the smooth outer wall surface has a portion that produces concave-convex changes in the inner and outer directions of the liquid storage box 6, and the portion with concave-convex changes constitutes the concave-convex portion 61, so that the area near the position where the concave-convex portion 61 is located is a smooth plane with height changes, so as to improve the trigger sensitivity when the concave-convex portion 61 contacts the swing trigger member 3.

[0139] In this embodiment, the concave-convex portion 61 can be designed in any shape, such as circular, square, elliptical, polygonal, and other shapes and structures. In this embodiment, in order to ensure the accuracy of the detection of the concave-convex portion 61, the concave-convex portions 61 provided on the liquid storage box 6 are generally of the same shape, thereby improving the convenience of replacing the liquid storage box 6 and improving the aesthetic appearance.

[0140] Preferably, if Figure 4 and Figure 10 As shown, in this embodiment, the liquid storage box 6 is provided with a marking cover 62, and the concave-convex portion 61 is provided on the marking cover 62. By providing the marking cover 62, processing the concave-convex portion 61 on the marking cover 62 is more convenient and simple than processing directly on the box body of the liquid storage box 6, thereby improving the production efficiency of the liquid storage box 6.

[0141] Furthermore, the identification cover 62 can be a separate component mounted on the top wall of the liquid storage box 6. Preferably, in this embodiment, the identification cover 62 is a partial structure of the liquid storage box 6 and is mounted on the top wall of the liquid storage box 6 near the front end. This allows the identification cover 62 to serve as both a carrier for the concave-convex portion 61 and a component of the liquid storage box 6, achieving multiple uses and reducing costs.

[0142] More preferably, the top wall of the liquid storage box 6 is provided with an opening, and the identification cover 62 is mounted on the opening. The identification cover 62 adopts a split structure, which is assembled into a whole to form a liquid storage box 6 with a complete independent closed chamber.

[0143] Alternatively, the identification cover 62 is integrally formed with the box body of the liquid storage box 6 , and the identification cover 62 and the liquid storage box 6 are integrally formed using a blow molding process, which simplifies the process and reduces the production cost.

[0144] Preferably, if Figure 4 and Figure 10 As shown, a one-way air-permeable valve 63 is installed on the identification cover 62 to balance the pressure difference between the inside and outside of the liquid storage box 6, thereby ensuring that the additive in the liquid storage box 6 can be smoothly sucked out.

[0145] The identification cover 62 is provided with a mounting hole for installing a one-way air valve 63, and the one-way air valve 63 is sealed and installed in the mounting hole. By installing the one-way air valve 63 on the identification cover 62 instead of setting it at other positions of the liquid storage box 6 body, the processing and manufacturing are convenient, and the processing technology of the liquid storage box 6 is further simplified.

[0146] like Figure 10 As shown, in this embodiment, the position information of the concave-convex portion 61 provided on the liquid storage box 6 includes the position information of the concave-convex portion 61 on the liquid storage box 6 .

[0147] For example: the concave-convex portion 61 provided on the detergent storage box 6 for containing detergent is located at position a, the concave-convex portion 61 provided on the rinse agent storage box 6 for containing rinse agent is located at position b, the concave-convex portion 61 provided on the disinfectant storage box 6 for containing disinfectant is located at position c, and so on.

[0148] In the second embodiment

[0149] like Figure 4 and Figure 10 As shown, the outer surface of the liquid storage box 6 described in this embodiment is provided with more than two concave-convex parts 61, and the concave-convex parts 61 are spaced apart from each other, so that each concave-convex part 61 is distributed at different positions of the liquid storage box 6 in a variable position manner. The combination of the number and position of the concave-convex parts 61 provided on the liquid storage box 6 corresponds to the type of additive stored in the liquid storage box 6.

[0150] In this embodiment, the number of the concave-convex portions 61 is the number of the concave-convex portions 61 provided on the outer surface of the liquid storage box 6; for example:

[0151] The detergent storage box 6 for containing detergent is provided with two concave-convex parts 61, the rinse agent storage box 6 for containing rinse agent is provided with three concave-convex parts 61, the disinfectant storage box 6 for containing disinfectant is provided with one concave-convex part 61, and so on.

[0152] At the same time, in this embodiment, the position information of the concave-convex parts 61 includes the distance information between the concave-convex parts 61, the relative spatial orientation information, the position information set on the liquid storage box 6, etc. For example:

[0153] A concave-convex portion 61 is respectively provided at positions a, b and c on the detergent storage box 6 for containing detergent, a concave-convex portion 61 is respectively provided at positions a and b on the rinse agent storage box 6 for containing rinse agent, a concave-convex portion 61 is respectively provided at positions a and c on the disinfectant storage box 6 for containing disinfectant, and so on.

[0154] Of course, in this embodiment, the quantity information and position information of the concave and convex parts 61 can also be combined to correspond to a greater number of additive types.

[0155] Example 3

[0156] like Figures 1 to 10 As shown, this embodiment further provides an additive delivery device 7, comprising the liquid storage box 6 in the second embodiment and a receiving portion 71 for installing the liquid storage box 6, wherein the receiving portion 71 is provided with the intelligent identification component 1 in the first embodiment.

[0157] In this embodiment, at least one concave-convex portion 61 is provided on the outer wall of the liquid storage box 6 . The number and position of the concave-convex portions 61 or any combination thereof corresponds to the type of additive stored in the liquid storage box 6 .

[0158] like Figures 1 to 4 As shown, the position of the swing trigger member 3 corresponds to the position of the concave-convex portion 61, and can cover all the concave-convex portions 61 on different types of additive storage boxes 6; each concave-convex portion 61 on the storage box 6 abuts against the swing trigger member 3 at the corresponding position, squeezing the swing trigger member 3 to swing toward the direction close to the conductive spring piece 21.

[0159] The concave-convex portion 61 can be set on the upper and lower, left and right side walls of the liquid storage box 6, as long as it can be ensured that after the liquid storage box 6 is inserted into the accommodating portion 71, the concave-convex portion 61 can be in relative contact with the swing trigger part 3 of the intelligent identification component 1, and the protrusion will produce an extrusion contact with the swing trigger part 3, so that the contact switch 2 generates a trigger signal.

[0160] Preferably, in this embodiment, Figure 4 and Figure 10 As shown, the concave-convex portion 61 is provided on the top wall of the liquid storage box 6, and the accommodating portion 71 is composed of the accommodating portion 71 for the liquid storage box 6 to be installed and an integrated cover plate 72 provided above the accommodating portion 71. The intelligent identification component 1 is correspondingly installed on the integrated cover plate 72. The water inlet channel of the additive dispensing device 7 is integrated on the integrated cover plate 72.

[0161] Furthermore, if Figure 1 As shown, the integrated cover plate 72 is provided with a mounting opening 721 for mounting the smart identification component 1. The mounting opening 721 is adapted to the outer peripheral wall of the mounting shell 4 of the smart identification component 1. The upper peripheral wall of the mounting shell 4 is provided with an outwardly protruding connecting portion 411, and the connecting portion 411 is provided with a threaded hole 4111. The integrated cover plate 72 is correspondingly provided with a bolt column 722, and the smart identification component 1 is fixed to the integrated cover plate 72 via the screw thread connection.

[0162] Preferably, if Figure 1 As shown, the connecting parts 411 include two, which are diagonally arranged on the outer peripheral wall of the mounting shell 4, and the bolt columns 722 are also two, which are diagonally symmetrically arranged at the mounting opening 721. The connecting parts 411 and the bolt columns 722 are arranged diagonally, and the smart identification component 1 can be stably and firmly mounted on the integrated cover plate 72 with two screws, and the connection is reliable.

[0163] More preferably, the system further includes an identification unit for determining the type of additive in the liquid storage box 6 based on information from the contact switch 2 in contact with the concave-convex portion 61 .

[0164] In this embodiment, an identification unit is integrated with the additive dispensing device 7 or independently provided externally. The identification unit can obtain information of the contact switch 2 that is in contact with the concave-convex portion 61 when the swing trigger member 3 is pushed, and compare the obtained information of the contact switch 2 that is in contact with the concave-convex portion 61 when the swing trigger member 3 is pushed with the pre-stored database to obtain information of the type of additive in the liquid storage box 6 corresponding to the obtained information of the contact switch 2 that is in contact with the concave-convex portion 61, so as to accurately judge the category of the additive in the liquid storage box 6.

[0165] In this embodiment, the identification unit can be directly set on the additive delivery device 7, or on a clothing processing device installed corresponding to the additive delivery device 7, or on a cloud server, mobile terminal or other intelligent terminal connected to the additive delivery device 7 for communication, etc.

[0166] This embodiment also provides a method for identifying the additive delivery device 7, including:

[0167] The liquid storage box 6 is inserted into the receiving portion of the additive delivery device 7;

[0168] The concave and convex portions 61 on the liquid storage box 6 abut against the swing trigger member 3 of the intelligent identification component 1, causing the swing trigger member 3 to swing toward the conductive spring 21, pushing the conductive spring 21 at the corresponding position to contact and conduct with the terminal 22;

[0169] The type of additive in the liquid storage box 6 is determined based on the signal information of the connection terminals 22 that are in contact with and conductive to the conductive springs 21 .

[0170] By employing the above method, when different types of liquid storage cartridges 6 are inserted into the receptacle of the additive dispensing device 7, the different positions and / or numbers of concave-convex portions 61 on the liquid storage cartridges 6 will come into contact with the corresponding swing trigger members 3, pushing the different swing trigger members 3 upward, causing the corresponding conductive springs 21 to contact and connect with the terminal 22, thereby achieving circuit conduction and outputting a signal. Because the number and / or positions of the concave-convex portions 61 on the liquid storage cartridges 6 for different types of additives vary, they push different swing trigger members 3, and the on-off conditions of each contact switch 2 also vary. This allows the intelligent identification component 1 to output different combinations of detection signals, achieving the effect of accurately identifying the type of additive represented by the concave-convex portion 61 on the liquid storage cartridge 6.

[0171] In this application, after the swing trigger member 3 is pushed into the accommodating portion 71 by the liquid storage box 6, the differentiated concave and convex features on the liquid storage box 6 will be squeezed and contacted with the rocker arm pushing portion 33 of the swing trigger member 3, pushing the rocker arm body 31 at the corresponding position to move upward around the rotation axis, and the spring pushing portion 32 above the rocker arm body 31 will push the conductive spring 21 to contact the terminal 22 or conductive contact on the PCB board 23, thereby realizing the circuit conduction and outputting the signal.

[0172] The swing trigger 3 converts the forward and backward movement of the liquid storage box 1 into the up and down movement of the swing arm body 31, thereby triggering the corresponding contact switch 2. The swing trigger 3 can achieve the function of force reversal transmission, providing greater convenience for the configuration of the intelligent identification component 1. Different liquid storage boxes 6 have different concave and convex portions 61, which push different swing triggers 3, and can output different combination signals, thereby realizing the identification of the type of additive stored in the liquid storage box 6.

[0173] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
