Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a dispensing structure, dispensing device, and electrical equipment. Background Technology

[0002] Dishwasher detergent dispensing systems typically require adding detergent before each use. Detergents on the market come in various forms, such as powder, liquid, tablets, and pods. However, current dishwasher detergent dispensing systems often only support one type of detergent. For example, some dishwashers' automatic dispensing systems only accept liquid detergent, not powder or tablets, thus failing to meet diverse user needs.

[0003] It is evident that the delivery system has poor versatility for various delivery formats, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the present invention provides a dispensing structure, dispensing device and electrical equipment to solve the problem that the dispensing system has poor versatility for dispensing various forms of objects, which leads to a poor user experience.

[0005] Firstly, this utility model provides a delivery structure, including: The bracket is equipped with a trigger unit; A turntable is rotatably mounted on the support via a drive mechanism; the turntable is provided with multiple receiving cavities, which are distributed along the circumference of the turntable; A sealed inner cover is closable at the opening of each of the receiving cavities; A locking assembly is disposed on the turntable in a one-to-one correspondence with the sealing inner cover; the locking assembly has a locking position that restricts the closed state of the sealing inner cover and an unlocking position that unlocks the sealing inner cover; An outer cover is fastened to the bracket and the turntable is housed between the outer cover and the bracket. The outer cover is provided with a dispensing port. The position of the dispensing port corresponds to the position of the trigger part. When the turntable rotates under the drive of the drive mechanism, causing the locking component to move to the trigger part, the trigger part pushes the locking component from the locked position to the unlocked position, and the sealing inner cover pops open, allowing the object to be placed in the receiving cavity to be released from the placement port.

[0006] Beneficial Effects: In this invention's dispensing structure, when the turntable is not rotating, all locking components are in the locked position, limiting their respective sealing inner covers. All sealing inner covers are securely fastened to the openings of the corresponding receiving cavities on the turntable, reliably sealing the items to be dispensed within the cavities. The turntable rotates under the action of the drive mechanism. When the locking components on the turntable rotate to contact the trigger part on the bracket, the reaction force of the trigger part moves the locking components to the unlocked position, releasing the limitation on the sealing inner covers. At this time, the sealing inner covers pop open, and the dispensing port on the outer cover corresponds precisely to the opening of the receiving cavity, allowing the items to be dispensed to be released from the dispensing port. This design allows for the placement of various forms of items, including liquids, powders, and lumps, in the receiving cavity. While ensuring a sealing effect, the items can be released from the dispensing port under gravity when the sealing inner covers are opened. The dispensing structure has good versatility for various forms of items, meeting diverse washing needs and improving the user experience.

[0007] In one optional embodiment, the turntable has a plurality of through holes along its axial direction; the locking assembly includes: The upper arm of the snap fastener has a rotating shaft and a locking arm located at the first end of the rotating shaft. The locking arm is located on the first side of the turntable and is used to snap into the sealing inner cover. The lower latch arm is rotatably mounted on the second side of the turntable, and the second end of the rotating shaft passes through the through hole and engages with the lower latch arm; the trigger part is used to push the lower latch arm.

[0008] Beneficial effects: The locking assembly adopts a split design with an upper latch arm on the first side of the turntable and a lower latch arm on the second side of the turntable. The mechanical connection is achieved by a rotating shaft passing through the through hole of the turntable. This ensures that the latching force of the locking arm on the sealing inner cover and the triggering thrust of the lower latch arm act in opposite directions along the same axis, forming a force balance. Compared with a locking structure set on one side, this design can avoid the locking assembly from tilting and loosening due to force on one side. It ensures that the sealing inner cover is always tightly fastened to the opening of the receiving cavity when not in the dispensing state. Even if the receiving cavity contains liquid, paste or other easily leaking dispensing materials, it can achieve zero leakage sealing, further enhancing the sealing adaptability to various forms of dispensing materials. The lower arm of the latch is independently located on the second side of the turntable and directly engages with the triggering part on the bracket. This short triggering path and direct force application prevent accidental activation or premature unlocking of the sealed inner cover due to direct contact between the triggering part and the locking arm. Simultaneously, the engagement of the rotating shaft and the through hole forms a clear pivot point, ensuring that when the lower arm is subjected to triggering force, it is precisely transmitted to the locking arm via the rotating shaft. This guarantees that the sealed inner cover only unlocks and pops open synchronously when the receiving cavity is fully aligned with the outer cover's dispensing opening, completely eliminating the problem of premature drop of the dispensing item or misalignment of the dispensing position, thus improving the accuracy of the dispensing action. Furthermore, the locking arm of the upper arm of the latch, as an independent functional component, can be flexibly adjusted in length, angle, and latching protrusion structure according to the latching requirements of the sealed inner cover (such as the shape and thickness of the latching groove), without altering the assembly relationship between the lower arm and the rotating shaft, resulting in high adaptability to different sealed inner cover structures.

[0009] In one optional embodiment, the locking arm is provided with a first guide slope, and the sealing inner cover is provided with a second guide slope, wherein the first guide slope and the second guide slope are inclined in opposite directions.

[0010] Beneficial effects: The first guide slope of the locking arm and the second guide slope of the sealing inner cover are inclined in opposite directions, forming a wedge fit. When installing or resetting the sealing inner cover, there is no need to precisely align the locking arm and the sealing inner cover. Simply press the sealing inner cover against the opening of the receiving cavity downwards, and the two guide slopes will automatically correct the positional deviation through the slope guidance, guiding the locking arm to slide along the slope and elastically avoid it, ultimately making the locking structure of the sealing inner cover precisely engage with the locking arm. Compared with the snap-fit ​​design without a guide structure, there is no need to manually align the snap-fit ​​groove and the locking arm. This design realizes the blind snap-fit ​​installation of the sealing inner cover, simplifying the operation steps. It is especially suitable for users to quickly reset the sealing inner cover after adding items, significantly improving the convenience of user operation. When the inner sealing cover is pressed, the guide ramp decomposes the axial pressing force into a lateral component along the ramp, allowing the locking arm to deform smoothly and elastically and gradually engage with the locking structure of the inner sealing cover. This avoids insecure engagement or uneven force on the inner sealing cover caused by rigid collisions. This progressive engagement method ensures that the locking arm and the locking surface of the inner sealing cover are fully in contact, the contact pressure is evenly distributed, and the engagement force is evenly transmitted, further enhancing the sealing effect of the inner sealing cover on the receiving cavity. Even if the receiving cavity contains easily leaking liquids or volatile powders, it can effectively prevent leakage and volatilization, improving the reliability of the seal.

[0011] In one optional embodiment, the locking arm is provided with a plurality of reinforcing ribs, which are distributed along the extension direction of the locking arm.

[0012] Beneficial effects: The locking arm must withstand dual forces during operation: the lateral squeezing force when the inner cover is engaged (a component force from the guide ramp) and the torsional force when unlocking (the trigger force of the latching arm transmitted through the pivot). Multiple reinforcing ribs distributed along the extension direction form a skeletal support inside the locking arm, significantly improving its bending and torsional stiffness. Compared to thin-walled structures without reinforcing ribs, this effectively prevents bending, deformation, or warping of the locking arm due to long-term stress, ensuring that the locking arm always maintains precise positioning accuracy and fits tightly with the inner cover's snap-fit ​​structure. Even in scenarios with high-frequency opening and closing or when the cavity is fully loaded with heavy objects (such as block detergent beads or high-viscosity liquid detergent), it can maintain stable locking force, preventing leakage of the contents caused by loosening or falling off of the inner cover. The locking arm's resistance to deformation is significantly improved, and the locking state is more stable. Furthermore, the reinforcing ribs are evenly distributed along the extension direction of the locking arm, which can disperse the compressive and torsional forces borne by the locking arm to the entire locking arm body and the connection point with the upper arm of the latch (the pivot point), avoiding stress concentration at the latching end or root of the locking arm (the easily broken area). For example, when the sealing inner cover applies lateral force through the guide ramp, the reinforcing ribs can gradually transmit this force from the latching end to the pivot point, ensuring even force transmission and avoiding local stress concentration. This reduces the risk of cracking of the locking arm due to stress concentration, and is especially suitable for scenarios where the locking arm uses elastic materials, balancing the elasticity requirements of the material with the structural strength requirements.

[0013] In one optional embodiment, a limit post and a locking reset component are further provided on the second side of the turntable; The lower arm of the buckle includes: The sleeve has a shaft hole that mates with the rotating shaft; A drive arm is disposed on the periphery of the sleeve, and the drive arm is connected to the turntable through the locking reset member; the extension direction of the drive arm is opposite to the extension direction of the locking arm. A limiting arm is disposed on the periphery of the sleeve and forms a non-zero angle with the driving arm; the limiting arm is used to cooperate with the limiting post.

[0014] Beneficial Effects: The drive arm and locking arm extend in opposite directions and are connected to the turntable via a latch reset component (such as a torsion spring or tension spring). The reset component stores energy upon triggering unlocking and automatically returns to its original position after unlocking. When the turntable rotates and the drive arm contacts the trigger, the trigger pushes the drive arm to rotate around the sleeve shaft hole, unlocking the shaft and locking arm. As the turntable continues to rotate, the drive arm disengages from the trigger, releasing the elastic potential energy of the latch reset component, driving the drive arm to rotate in the opposite direction. This, through the shaft, quickly resets the locking arm to the locked position, preparing for the next sealing of the inner cover. Compared to designs without a reset structure, this design achieves automatic reset after unlocking, ensuring the locking assembly is always in a locked state. This avoids problems such as the sealing of the inner cover failing to close or leakage of the dispensed material due to the locking arm not resetting, ensuring the continuous and stable operation of the dispensing structure. Simultaneously, the reverse-extending drive arm design extends the lever arm of the reset force, allowing the reset component to generate sufficient torque with a smaller elastic force to reset the locking arm, reducing fatigue wear and extending its service life. In addition, the drive arm and the locking arm extend in opposite directions along the circumference of the sleeve. When the drive arm is pushed by the trigger, the locking arm generates a reverse unlocking force. The two forces are distributed in opposite directions around the rotating shaft at 180°, forming a torque balance and reducing the off-center load on the turntable.

[0015] In one alternative embodiment, the inner sealing cover is pivotally connected to the turntable, and an inner cover reset member is provided at the pivot of the inner sealing cover.

[0016] Beneficial effects: The sealed inner cover is pivotally connected to the turntable and equipped with an inner cover reset component (such as a torsion spring or spiral spring). Under normal conditions, the inner cover reset component is in a pre-tightened state, providing a continuous spring-opening torque for the sealed inner cover, and its spring-opening is only restricted by the locking arm of the locking assembly. When the locking assembly unlocks and the locking arm disengages from the sealed inner cover, the elastic potential energy of the inner cover reset component is released instantaneously, driving the sealed inner cover to spring open rapidly around the pivot. This design achieves a synchronous response of unlocking and opening the cover, avoiding delays or incomplete opening caused by the adhesion of the dispensing material or insufficient gravity, ensuring smooth release of various dispensing materials such as liquids, powders, and lumps, and significantly improving the accuracy and efficiency of the dispensing action.

[0017] In one optional embodiment, the outer cover is provided with a guide rib on the side facing the sealing inner cover, the guide rib extending circumferentially along the outer cover, and the end of the guide rib extending to the dispensing port.

[0018] Beneficial effects: After the dispensing is completed, the turntable continues to rotate, and the pop-out sealing inner cover rotates with the turntable and gradually contacts the guide rib. The inclined or arc-shaped structure of the guide rib extending circumferentially along the outer cover will generate continuous radial pressure on the sealing inner cover, forcing the sealing inner cover to rotate in the opposite direction around the pivot until it re-engages and locks with the locking arm.

[0019] In one optional embodiment, an overflow port is provided at the edge of the outer cover, and the overflow port is spaced apart from the dispensing port.

[0020] Beneficial effect: The overflow port allows water entering the dispensing structure from the outside to flow back through the overflow port. For example, during a dishwasher wash, water sprayed by the spray arms will enter the interior through the dispensing port on the outer cover and the gap between the outer cover and the bracket. To prevent the accumulation of dirty water inside, an overflow port is provided to drain it out.

[0021] In one optional embodiment, the turntable is further provided with protrusions that correspond one-to-one with the inner sealing cover, and the bracket or the outer cover is provided with a micro switch, which can be triggered by the protrusions when the turntable rotates.

[0022] Beneficial effects: The raised structures correspond one-to-one with the sealed inner covers and rotate synchronously with the turntable. When a raised structure triggers a microswitch, the microswitch sends a clear electrical signal to the control board. Since each raised structure corresponds to a sealed inner cover, i.e., a receiving cavity, the control board can accurately identify the position of the receiving cavity currently rotated to the microswitch trigger position by the signal trigger sequence and trigger interval, achieving precise positioning of the turntable. This allows the control board to monitor the specific position of each receiving cavity in real time, providing data support for precise control of the delivery action. In addition, the microswitch uses mechanical contact triggering, ensuring stable contact pressure and trigger stroke between the raised structure and the microswitch, resulting in a clear and interference-free output electrical signal, avoiding delivery misalignment caused by position detection errors.

[0023] Secondly, this utility model also provides a dispensing device, including the dispensing structure described in any of the above claims.

[0024] Beneficial effects: Since the dispensing device includes the dispensing structure of this utility model, it has the same technical effects as the dispensing structure, which will not be described in detail here.

[0025] Thirdly, this utility model also provides an electrical device, comprising: case; A dispensing device, which is mounted on the housing via the bracket.

[0026] Beneficial effects: Since the electrical equipment includes the dispensing device of this utility model, it has the same technical effects as the dispensing device, which will not be described in detail here.

[0027] In one alternative embodiment, the housing includes a door, and the dispensing device is detachably mounted on the door.

[0028] Beneficial effects: The dispensing device is detachably installed on the door. Users only need to open the door to remove the entire dispensing device, which facilitates the addition of items to be dispensed and the maintenance of the dispensing device.

[0029] In one alternative implementation, the electrical appliance is a dishwasher.

[0030] Beneficial effects: When the dispensing structure of this utility model is applied to a dishwasher for dispensing detergent, the dishwasher can use various forms of detergent such as dishwasher powder, dishwasher liquid, dishwasher tablets and dishwasher pods, which is highly versatile and provides a better user experience.

[0037] The following is combined with Figures 1 to 13 The following describes embodiments of the present invention.

[0038] According to embodiments of the present invention, on the one hand, such as Figures 1 to 7 as well as Figure 10 As shown, a delivery structure is provided, including: The bracket 100 is equipped with a trigger part 101; A turntable 200 is rotatably mounted on the support 100 via a drive mechanism 600; the turntable 200 is provided with a plurality of receiving cavities 201, which are distributed along the circumference of the turntable 200; A sealing inner cover 300 is closably disposed at the opening of each of the receiving cavities 201; A locking component 400 is disposed on the turntable 200 in a one-to-one correspondence with the sealing inner cover 300; the locking component 400 has a locking position that restricts the closed state of the sealing inner cover 300 and an unlocking position that unlocks the sealing inner cover 300. The outer cover 500 is fastened to the bracket 100 and the turntable 200 is housed between the outer cover 500 and the bracket 100. The outer cover 500 is provided with a dispensing port 501. The position of the dispensing port 501 corresponds to the position of the trigger part 101. When the turntable 200 rotates under the drive of the drive mechanism 600, causing the locking component 400 to move to the trigger part 101, the trigger part 101 pushes the locking component 400 from the locked position to the unlocked position, and the sealing inner cover 300 pops open, allowing the object to be placed in the receiving cavity 201 to be released from the delivery port 501.

[0039] In the dispensing structure of this utility model, when the turntable 200 is not rotating, all locking components 400 are in the locked position, limiting their respective sealing inner covers 300. All sealing inner covers 300 are sealed and fastened to the openings of the corresponding receiving cavities 201 on the turntable 200, so that the items to be dispensed in the receiving cavities 201 are reliably sealed. The turntable 200 of the dispensing structure rotates under the action of the drive mechanism 600. When the locking components 400 on the turntable 200 rotate to contact the trigger part 101 on the bracket 100, under the reaction action of the trigger part 101, the locking components 400 move to the unlocked position, releasing the limitation on the sealing inner covers 300. At this time, the sealing inner covers 300 pop open, and the dispensing port 501 on the outer cover 500 corresponds exactly to the opening of the receiving cavity 201, and the items to be dispensed are released from the dispensing port 501. With this design, the receiving cavity 201 can hold various forms of items to be placed, including liquids, powders, and blocks. While ensuring a sealing effect, when the inner sealed cover 300 is opened, the items to be placed can be released from the dispensing port 501 under the action of gravity. The dispensing structure has good versatility for various forms of items, which can meet the various washing needs of users and improve the user experience.

[0040] In some embodiments, such as Figure 3 As shown, the turntable 200 has multiple through holes along its axial direction; the locking assembly 400 includes: The upper arm 401 of the buckle is provided with a rotating shaft 4011 and a locking arm 4012 located at the first end of the rotating shaft 4011. The locking arm 4012 is located on the first side of the turntable 200 and is used to engage with the sealing inner cover 300. The lower latch arm 402 is rotatably disposed on the second side of the turntable 200, and the second end of the rotating shaft 4011 passes through the through hole and engages with the lower latch arm 402; the trigger part 101 is used to push the lower latch arm 402.

[0041] The locking assembly 400 adopts a split design with an upper latch arm 401 located on the first side of the turntable 200 and a lower latch arm 402 located on the second side of the turntable 200. The mechanical connection is achieved by the rotating shaft 4011 passing through the through hole of the turntable 200. This allows the latching force of the locking arm 4012 on the sealing inner cover 300 and the triggering thrust of the lower latch arm 402 to act in opposite directions along the same axis, forming a force balance. Compared with a locking structure set on one side, this design can avoid the locking assembly 400 from being tilted and loosened due to force on one side. It ensures that the sealing inner cover 300 is always tightly fastened to the opening of the receiving cavity 201 when not in the dispensing state. Even if the receiving cavity 201 contains liquid, paste or other easily leaking dispensing materials, it can achieve zero leakage sealing, further enhancing the sealing adaptability to various forms of dispensing materials. The lower latch arm 402 is separately located on the second side of the turntable 200 and directly engages with the trigger part 101 on the bracket 100. The trigger path is short and the force is direct, which can avoid the situation where the inner sealed cover 300 is accidentally activated or prematurely unlocked due to direct contact between the trigger part 101 and the locking arm 4012. At the same time, the engagement of the rotating shaft 4011 and the through hole forms a clear rotation fulcrum, so that when the lower latch arm 402 is subjected to the trigger thrust, it can be accurately transmitted to the locking arm 4012 through the rotating shaft 4011. This ensures that the inner sealed cover 300 is only unlocked and popped open when the receiving cavity 201 is completely aligned with the delivery port 501 of the outer cover 500, completely eliminating the problem of premature drop of the delivery object or displacement of the delivery position and improving the accuracy of the delivery action. In addition, the locking arm 4012 of the upper arm 401 of the buckle is an independent functional component. The length, angle and locking protrusion structure of the locking arm 4012 can be flexibly adjusted according to the snap-fit ​​requirements of the inner sealing cover 300 (such as the shape and thickness of the snap-fit ​​groove). There is no need to change the assembly relationship between the lower arm 402 of the buckle and the rotating shaft 4011, which has high adaptability to different structures of the inner sealing cover 300.

[0042] In some embodiments, such as Figure 4 As shown, the locking arm 4012 is provided with a first guide slope 40121, and the sealing inner cover 300 is provided with a second guide slope 303. The first guide slope 40121 and the second guide slope 303 have opposite inclination directions.

[0043] The first guide slope 40121 of the locking arm 4012 and the second guide slope 303 of the sealing inner cover 300 have opposite inclination directions, forming a wedge fit. When installing or resetting the sealing inner cover 300, there is no need to precisely align the locking arm 4012 and the locking inner cover 300. Simply press the sealing inner cover 300 against the opening of the receiving cavity 201 downwards, and the two guide slopes will automatically correct the positional deviation through the slope guidance, guiding the locking arm 4012 to slide along the slope and elastically avoid it, so that the locking structure of the sealing inner cover 300 and the locking arm 4012 can be precisely locked. Compared with the locking design without a guide structure, there is no need to manually align the locking groove and the locking arm 4012. This design realizes the blind snap installation of the sealing inner cover 300, which simplifies the operation steps. It is especially suitable for users to quickly reset the sealing inner cover 300 after adding the contents, which significantly improves the convenience of user operation. When the inner sealing cover 300 is pressed, the guide slope decomposes the axial pressing force into a lateral component along the slope, causing the locking arm 4012 to deform smoothly and elastically and gradually engage with the locking structure of the inner sealing cover 300. This avoids insecure engagement or uneven force on the inner sealing cover 300 caused by rigid collision. This progressive engagement method ensures that the locking arm 4012 and the locking surface of the inner sealing cover 300 are fully fitted, the contact pressure is evenly distributed, and the engagement force is evenly transmitted. This further enhances the sealing effect of the inner sealing cover 300 on the receiving cavity 201. Even if the receiving cavity 201 contains easily leaking liquid or volatile powder, it can effectively prevent leakage and volatilization, and improve the reliability of the seal.

[0044] In some embodiments, such as Figure 4 As shown, the locking arm 4012 is provided with a plurality of reinforcing ribs 40122, and the plurality of reinforcing ribs 40122 are distributed along the extension direction of the locking arm 4012.

[0045] The locking arm 4012 must withstand dual forces during operation: the lateral compressive force when the inner sealing cover 300 is engaged (a component force from the guide ramp), and the torsional force during unlocking (the triggering force of the lower latch arm 402 transmitted through the pivot 4011). Multiple reinforcing ribs 40122 distributed along the extension direction effectively form a skeletal support within the locking arm 4012, significantly improving its bending and torsional stiffness. Compared to a thin-walled structure without reinforcing ribs 40122, this effectively avoids… The locking arm 4012 is designed to prevent bending, deformation, or warping caused by long-term stress. It ensures that the locking arm 4012 maintains precise positioning and fits tightly against the snap-fit ​​structure of the sealing inner cover 300. Even under conditions of frequent opening and closing or when the receiving cavity 201 is fully loaded with heavy objects (such as granular detergent beads or high-viscosity liquid detergent), it maintains stable locking force, preventing leakage of the contents due to loosening or detachment of the sealing inner cover 300. The deformation resistance of the locking arm 4012 is significantly improved, resulting in a more stable locking state. Furthermore, the reinforcing ribs 40122 are evenly distributed along the extension direction of the locking arm 4012, distributing the compressive and torsional forces borne by the locking arm 4012 throughout the entire locking arm 4012 body and the connection point with the upper snap-fit ​​arm 401 (at the pivot 4011), preventing stress concentration at the snap-fit ​​end or root of the locking arm 4012 (a region prone to breakage). For example, when the inner sealing cover 300 applies a lateral force through the guide slope, the reinforcing rib 40122 can gradually transmit the force from the snap-fit ​​end to the rotating shaft 4011, so that the force is transmitted evenly, avoiding local stress concentration and reducing the risk of cracking of the locking arm 4012 due to stress concentration. It is especially suitable for scenarios where the locking arm 4012 uses elastic materials, balancing the elasticity requirements of the material and the structural strength requirements.

[0046] In some embodiments, such as Figure 6 As shown, the second side of the turntable 200 is also provided with a limit post 202 and a locking reset component 203; The lower arm 402 of the latch includes: The sleeve 4023 has a shaft hole that mates with the rotating shaft 4011; A drive arm 4021 is disposed on the periphery of the sleeve 4023, and the drive arm 4021 is connected to the turntable 200 through the locking reset member 203; the extension direction of the drive arm 4021 is opposite to the extension direction of the locking arm 4012. The limiting arm 4022 is disposed on the periphery of the sleeve 4023 and forms a non-zero angle with the driving arm 4021; the limiting arm 4022 is used to cooperate with the limiting post 202.

[0047] The drive arm 4021 extends in the opposite direction to the locking arm 4012 and is connected to the turntable 200 via a latch reset component 203 (such as a spring, torsion spring, or tension spring). The reset component stores energy when unlocking is triggered and automatically returns to its original position after unlocking. When the turntable 200 rotates and the drive arm 4021 contacts the trigger part 101, the trigger part 101 pushes the drive arm 4021 to rotate around the shaft hole of the sleeve 4023, thereby unlocking the rotating shaft 4011 and the locking arm 4012. When the turntable 200 continues to rotate, after the drive arm 4021 disengages from the trigger part 101, the elastic potential energy of the latch reset component 203 is released, driving the drive arm 4021 to rotate in the opposite direction. This drives the locking arm 4012 to quickly return to the locked position via the rotating shaft 4011, preparing for the next sealing of the inner cover 300. Compared to designs without a reset structure, this design achieves automatic reset after unlocking, ensuring that the locking assembly 400 is always in a locked state. This avoids problems such as the sealing inner cover 300 failing to close and leakage of the dispensed material due to the locking arm 4012 not resetting, thus ensuring the continuous and stable operation of the dispensing structure. Simultaneously, the reverse-extending drive arm 4021 design extends the lever arm of the reset force, allowing the reset component to generate sufficient torque with a smaller elastic force to drive the locking arm 4012 to reset, reducing fatigue wear on the reset component and extending its service life. Furthermore, the drive arm 4021 and the locking arm 4012 extend in opposite directions circumferentially along the sleeve 4023. When the drive arm 4021 is pushed by the trigger part 101, the locking arm 4012 generates a reverse unlocking force. The two forces are distributed in opposite directions at 180° around the rotating shaft 4011, forming a torque balance and reducing the off-center load on the turntable 200.

[0048] In some embodiments, such as Figure 11 As shown, the inner sealing cover 300 is pivotally connected to the turntable 200, and an inner cover reset member 302 is provided at the pivot 301 of the inner sealing cover 300.

[0049] The inner sealing cover 300 is pivotally connected to the turntable 200 and equipped with an inner cover reset component 302 (such as a torsion spring or a spiral spring). Under normal conditions, the inner cover reset component 302 is in a pre-tightened state, providing a continuous spring-opening torque for the inner sealing cover 300, and its spring-opening is only restricted by the locking arm 4012 of the locking assembly 400. When the locking assembly 400 is unlocked and the locking arm 4012 disengages from the inner sealing cover 300, the elastic potential energy of the inner cover reset component 302 is released instantaneously, driving the inner sealing cover 300 to quickly spring open around the pivot 301. This design achieves a synchronous response of unlocking and opening the cover, avoiding delays or incomplete opening caused by the adhesion of the dispensing material or insufficient gravity, ensuring that various dispensing materials such as liquids, powders, and lumps can be released smoothly, significantly improving the accuracy and efficiency of the dispensing action.

[0050] In some embodiments, such as Figure 5As shown, the outer cover 500 is provided with a guide rib 502 on the side facing the sealing inner cover 300. The guide rib 502 extends circumferentially along the outer cover 500, and the end of the guide rib 502 extends to the dispensing port 501.

[0051] After the deployment is complete, the turntable 200 continues to rotate. The inner sealing cover 300, in its pop-out state, rotates with the turntable 200 and gradually contacts the guide rib 502. The inclined or arc-shaped structure of the guide rib 502, extending circumferentially along the outer cover 500, exerts continuous radial pressure on the inner sealing cover 300, forcing it to rotate in the opposite direction around the pivot 301 until it re-engages and locks with the locking arm 4012. The state of the inner sealing cover 300 during the reverse engagement process under the action of the guide rib 502 is described in [reference needed]. Figure 8 and Figure 9 , Figure 7 This is the state when the lock is re-engaged.

[0052] In some embodiments, such as Figure 5 As shown, an overflow port 503 is provided at the edge of the outer cover 500, and the overflow port 503 is spaced apart from the dispensing port 501.

[0053] The overflow port 503 allows water entering the dispensing structure from the outside to flow back through the overflow port 503. For example, when the dishwasher is washing, the water sprayed by the spray arm will enter the interior through the dispensing port 501 of the outer cover 500 and the gap between the outer cover 500 and the bracket 100. In order to prevent dirty water from accumulating inside, the overflow port 503 is provided to discharge it.

[0054] In some embodiments, the turntable 200 is further provided with protruding structures (not shown in the figure) that correspond one-to-one with the inner sealing cover 300, and the bracket 100 or the outer cover 500 is provided with micro switches (not shown in the figure). When the turntable 200 rotates, the protruding structures can trigger the micro switches.

[0055] Each raised structure corresponds one-to-one with a sealed inner cover 300 and rotates synchronously with the turntable 200. When a raised structure triggers a microswitch, the microswitch sends a clear electrical signal to the control board. Since each raised structure corresponds to a sealed inner cover 300, i.e., a receiving cavity 201, the control board can accurately identify the position of the receiving cavity 201 that has rotated to the microswitch trigger position through the signal trigger sequence and trigger interval, thus achieving precise positioning of the turntable 200. This allows the control board to monitor the specific position of each receiving cavity 201 in real time, providing data support for precise control of the delivery action. In addition, the microswitch adopts mechanical contact triggering, ensuring stable contact pressure and trigger stroke between the raised structure and the microswitch, resulting in a clear and interference-free output electrical signal, avoiding delivery misalignment caused by position detection errors.

[0056] According to an embodiment of the present invention, another aspect provides a dispensing device, including the dispensing structure of the present invention.

[0057] Since the dispensing device includes the dispensing structure of this utility model, it has the same technical effect as the dispensing structure, which will not be described in detail here.

[0058] According to an embodiment of the present invention, another aspect provides an electrical device, comprising: case; The dispensing device is mounted on the housing via the bracket 100.

[0059] Since the electrical equipment includes the dispensing device of this utility model, it has the same technical effect as the dispensing device, which will not be described in detail here.

[0060] In some embodiments, the housing includes a door 700, and the dispensing device is detachably mounted on the door 700.

[0061] The dispensing device is detachably installed on the door 700. Users only need to open the equipment door 700 to remove the entire dispensing device, which facilitates the addition of the items to be dispensed and the maintenance of the dispensing device.

[0062] In some embodiments, the electrical appliance is a dishwasher.

[0063] The dispensing structure of this invention can be applied to a dishwasher for dispensing detergent. The dishwasher can use various forms of detergent such as dishwasher powder, dishwasher liquid, dishwasher tablets and dishwasher pods, which is highly versatile and provides a good user experience.

[0064] This utility model provides an automatic dispensing device for a dishwasher, which mainly consists of a support 100, a drive mechanism 600, a turntable 200, an outer cover 500, a sealing inner cover 300, a snap-on upper arm 401, a snap-on lower arm 402, several sealing rings, several springs, and several torsion springs.

[0065] like Figure 12 and Figure 13As shown, the bracket 100 of the automatic dispensing device is embedded inside the dishwasher door 700, sealed with the door 700 by a circumferential sealing ring, and fixed by a claw structure. The outer cover 500 has a dispensing port 501, and an overflow port is located below the outer cover 500 to allow washing water entering the outer cover 500 to flow back into the inner tub. A sealing ring is designed between the turntable 200 and the drive mechanism 600 to prevent washing water from entering the automatic dispensing device through the gaps between the bracket 100 and the drive mechanism 600, which could cause malfunction. The turntable 200 has several circumferentially designed receiving cavities 201, each with a sealing inner cover 300 and a sealing ring. The angle between two adjacent receiving cavities 201 and the center of the turntable 200 is α. A snap-fit ​​sealing ring 403 is provided between the upper snap-fit ​​arm 401 and the turntable 200 to prevent water leakage during rotation. The upper snap-fit ​​arm 401 and the lower snap-fit ​​arm are connected by a snap-fit.

[0066] Before use, manually remove the outer cover 500 of the dispensing device, open each of the inner sealing covers 300, and put detergent (dishwashing powder, dishwashing liquid, dishwashing pods, or dishwashing tablets are all acceptable) into the receiving cavity 201. Then close the inner sealing covers 300, and fasten the inner sealing covers 300 and the upper buckle arm 401. The inner sealing covers 300 and the receiving cavity 201 are sealed with a sealing ring to ensure that the detergent does not leak.

[0067] When detergent needs to be added, the drive mechanism 600 drives the turntable 200 to rotate. The drive mechanism 600 controls the receiving cavity 201 of the turntable 200 and the inner sealing cover 300 to align with the dispensing port 501 of the outer cover 500. At the same time, the lower latch arm 402 contacts the trigger part 101 of the bracket 100. The upper wall of the latch and the lower latch arm 402 rotate under the reaction force of the trigger part 101, releasing the lock of the inner sealing cover 300. The inner sealing cover 300 is pushed open by the internal pre-tightening torsion spring, and the detergent is exposed in the inner tank. It is washed and dissolved in the water by the water flow of the spray arm and participates in the washing water circulation.

[0068] In addition to using a controllable angle drive mechanism 600 for precise control, a protruding structure can also be set on the turntable 200. When the protruding structure presses against the micro switch, a signal is triggered to the control board to confirm the current position of the turntable 200.

[0069] After washing, the drive mechanism 600 drives the turntable 200 to rotate, with a rotation angle less than a. In this embodiment, it is a / 2 degrees. During rotation, the inner sealing cover 300 is pressed shut by the inner guide rib 502 of the outer cover 500, the lower latch arm 402 disengages from the trigger part 101, and the upper latch arm 401 is guided shut by the inclined surface of the inner sealing cover 300, thus completing the closing and locking of the inner sealing cover 300. Since the first guide inclined surface 40121 of the upper latch arm 401 is frequently subjected to force during operation, reinforcing ribs 40122 can be provided at intervals on the back side of the first guide inclined surface 40121 to improve the mechanical strength of the upper latch arm 401.

[0070] Limiting posts 202 are provided on the turntable 200 for each lower arm 402 of the latch to limit the position of the lower arm 402 of the latch and prevent the lower arm 402 of the latch from being pushed by the spring piece, causing the upper arm 401 of the latch and the lower arm 402 of the latch to enter the wrong position.

[0071] If the turntable 200 has n receiving cavities 201, after n additions, the dishwasher display panel will show that detergent is low, prompting the user to add detergent.

[0072] In this embodiment, n=8, allowing for 8 detergent dispensing cycles, automatically adjusted according to washing needs. The dishwasher is compatible with block, powder, liquid, and pod-type detergents. Furthermore, reliable sealing effectively prevents detergent from becoming damp and clumping (as block or pod-type detergents may deteriorate due to moisture).

[0073] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
