Description

Technical Field

[0001] The utility model relates to the field of beverage machines, in particular to a cleaning particle distribution device for automatically distributing cleaning particles to a beverage machine and the beverage machine. Background Art

[0002] Beverage machines on the market require that the brewing material and a certain amount of hot water be injected into the brewing chamber to prepare the beverage. Taking an automatic coffee machine as an example, coffee particles can be transported into the brewing chamber, and the coffee liquid can be discharged from the brewing chamber after brewing. In this way, the brewing chamber needs to be cleaned regularly to remove grease and particles left during the brewing process. In order to clean the brewing chamber, a cleaning material needs to be introduced into the brewing chamber for cleaning. The cleaning material can be a liquid detergent or solid cleaning particles.

[0003] When cleaning an automatic coffee machine, if a liquid detergent is used to clean the brewing chamber, the amount of detergent needs to be strictly controlled to avoid detergent residue. This requires setting up a complex system to control and detect the amount of detergent, and the user is also prone to spilling or overflowing the detergent when adding liquid detergent.

[0004] Of course, solid cleaning particles can also be used. When the brewing chamber needs to be cleaned, the user can manually add an appropriate amount of cleaning particles into the brewing chamber. For example, a channel with an external opening can be provided, and the channel can introduce the cleaning particles into the brewing chamber. The user only needs to put the cleaning particles into the external opening. However, each cleaning operation requires the user to perform it manually, which is time-consuming and labor-intensive, and brings great inconvenience to the user. Utility Model Content

[0045] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0046] It should be understood that the terms used herein, such as "upper", "above", "lower", "below", etc., indicating spatial relative positions, are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0047] The cleaning particle dispensing device in the specific embodiment of the utility model is described by taking the cleaning particle dispensing device 100 for a coffee machine as an example. The coffee machine generally includes a brewer, and beverage particles and water at a predetermined temperature are introduced into the brewer to prepare beverages. The coffee machine may also include a milk frother for producing hot milk or milk foam to make beverages of different flavors. Whether it is a brewer or a milk frother, it needs to be cleaned regularly to make the use of the coffee machine safer and more hygienic. The cleaning particles used for auxiliary cleaning can be added to the brewer or the milk frother, or the cleaning particles can be mixed with water through a cleaning channel and then introduced into the brewer or the milk frother. The brewer and the milk frother constitute the target cleaning chamber of the coffee machine. Of course, there may be other cavities that need to be cleaned, which can all be considered as the target cleaning chamber.

[0048] The cleaning particle dispensing device 100 can be connected to a beverage machine, in particular an automatically or semi-automatically operated beverage machine, such as a coffee machine or a tea machine, via a connecting device or a support. In the illustrated embodiment, the cleaning particle dispensing device 100 can be permanently integrated into the beverage machine; however, it can also be detachably mounted on the beverage machine via screws or a bracket of the dispensing device itself.

[0049] Reference Figures 1 to 3 As shown, in this embodiment, the cleaning particle dispensing device 100 includes a base 20, a storage container 30 disposed above the base 20, and a driving mechanism. The storage container 30 has a receiving cavity 31 for containing cleaning particles, and the base 20 is used to support the storage container 30 and install the driving mechanism. The driving mechanism includes a motor 41 and a conveying disk 42 driven to rotate by the motor 41, and the motor 41 and the conveying disk 42 are disposed on the base 20. The base 20 can be a separate structure or a frame structure of the beverage machine itself.

[0050] The storage container 30 includes a bottom plate 32, a driving mechanism is disposed below the bottom plate 32, a discharge port 321 communicating with the accommodating chamber 31 is disposed on the bottom plate 32, and the discharge port 321 is offset relative to the rotation axis of the conveying disk 42; at least one conveying chamber 422 is disposed on the conveying disk 42, and the conveying disk 42 can drive the conveying chamber 422 to correspond to the discharge port 321, so as to connect the conveying chamber 422 and the accommodating chamber 31; Figure 2 and 3As shown, the base 20 is provided with a delivery outlet 201; driven by the motor 41, the conveying disc 42 drives the conveying cavity 422 to communicate with the discharge port 321 and the delivery outlet 201 in sequence. The above-mentioned cleaning particle dispensing device 100, by driving the conveying disc 42, when the conveying cavity 422 is connected with the discharge port 321, the conveying disc 42 automatically receives the cleaning particles, and when the conveying cavity 422 is connected with the delivery outlet 201, the conveying disc 42 automatically outputs the cleaning particles, which can realize the quantitative automatic delivery of the cleaning particles, facilitate the metering of the cleaning particles and control the cleaning ability, and obtain the best cleaning effect, so that the beverage machine can fully automatically perform the cleaning process, thereby facilitating the use of the user.

[0051] In the present embodiment, one conveying chamber 422 is provided. In other optional embodiments, the number of conveying chambers 422 may be two, three or more. The multiple conveying chambers 422 are arranged at circumferential intervals along the conveying disk 42. When the conveying disk 42 rotates one circle, each conveying chamber 422 may be connected with the discharge port 321 and the delivery outlet 201 in sequence, thereby increasing the number of cleaning particles delivered per unit time when the rotation speed of the conveying disk 42 remains unchanged.

[0052] In a specific embodiment, three conveying chambers 422 are provided, and each conveying chamber 422 can only accommodate one cleaning particle. Each of the three conveying chambers 422 can be connected with the discharge port 321 driven by the conveying disk 42 to receive the cleaning particles, and then connected with the delivery outlet 201 to output the cleaning particles. The conveying disk 42 can deliver three cleaning particles by rotating one circle.

[0053] In particular, the axis of the motor 41 is perpendicular to the rotation axis of the conveyor disc 42, and the outer peripheral surface of the conveyor disc 42 is provided with a transmission tooth 421, and the motor 41 drives the conveyor disc 42 to rotate through the transmission tooth 421. The motor 41 is placed horizontally relative to the conveyor disc 42, which can reduce the height of the distribution device along the axial direction of the conveyor disc 42, and better utilize the space on the base 20 to make the distribution device more compact. A multi-stage gear can be arranged between the motor 41 and the conveyor disc 42 to transmit the power of the motor 41 to the conveyor disc 42, specifically, the output shaft of the motor 41 is connected to the worm 411, and a worm wheel 412 and a gear 413 are connected between the conveyor disc 42 and the worm 411, the worm 411 is meshed with the worm wheel 412, the worm wheel 412 is coaxially fixed with the gear 413, and the gear 413 is meshed with the transmission tooth 421 on the conveyor disc 42, that is, the motor 41 drives the conveyor disc 42 through a two-stage transmission. The transmission ratio of the worm gear is large, and the worm gear structure can realize the change of transmission direction. The transmission teeth 421 are directly arranged on the outer peripheral surface of the conveying disk 42 to realize the speed reduction transmission from the motor 41 to the conveying disk 42. While the transmission is reliable, the entire transmission mechanism is more compact. Other transmissions can also be used between the motor 41 and the conveying disk 42, such as one or more of bevel gear transmission, chain transmission, and belt transmission.

[0054] In some specific embodiments, the worm wheel 412 and the gear 413 are integrally arranged, so that the structure is simplified while also improving the strength and stability of the transmission.

[0055] A storage channel 322 extending toward the conveyor disc 42 is provided at the discharge port 321. One end of the storage channel 322 is in communication with the accommodating chamber 31, and the other end of the storage channel 322 can be intermittently in communication with the conveyor chamber 422. Specifically, the storage channel 322 has a storage space, and the storage space can be configured to accommodate at least a single cleaning particle. The size of the storage space is configured to accommodate only a single cleaning particle. When the conveyor disc 42 conveys a cleaning particle, another cleaning particle can be pre-stored in the storage space to ensure reliable delivery next time. Specifically, the conveyor chamber 422 can also be configured to accommodate only a single cleaning particle to ensure quantitative output of the cleaning particles.

[0056] Of course, the storage space can also be configured to accommodate a plurality of cleaning particles, and along the direction in which the cleaning particles enter the storage channel 322, the plurality of cleaning particles are sequentially stacked in the storage space, which can prevent the plurality of cleaning particles from being stuck in the storage space, and facilitate the cleaning particles to smoothly and accurately enter the transmission chamber 422 from the storage channel 322. In this embodiment, it can be understood that the plurality of cleaning particles are sequentially stacked up and down in the storage space. Of course, the storage space can also extend in a direction that is angled with the height direction of the beverage machine, and the plurality of cleaning particles are sequentially stacked in the storage space along the extension direction of the storage space.

[0057] Furthermore, a toggle rod 43 is provided in the accommodating chamber 31, and the toggle rod 43 is connected to the conveying disc 42, and the conveying disc 42 can drive the toggle rod 43 to rotate synchronously, so that the conveying disc 42 can drive the toggle rod 43 to stir the cleaning particles stored in the accommodating chamber 31 while conveying the cleaning particles, thereby preventing multiple cleaning particles from being stuck in a dead corner or being unable to enter the discharge port 321 due to being stuck together. The toggle rod 43 is directly driven to rotate by the conveying disc 42, and there is no need to configure an additional power drive for the toggle rod 43, which can improve the functional integration of the conveying disc 42 and will not increase the cost of the distribution device.

[0058] The toggle rod 43 may be in any shape that facilitates agitation of the cleaning particles. Figure 4 and Figure 5In this embodiment, the cleaning particles are spherical particles, the toggle rod 43 is coaxially arranged with the conveyor disk 42, and the outer contour of the cross section of the toggle rod 43 is configured as a polygon, and the radius difference between the circumscribed circle and the inscribed circle of the polygon is smaller than the radius of the cleaning particles. By setting the size of the toggle rod 43, it is possible to smoothly stir the cleaning particles, and also reduce the probability of the toggle rod 43 being stuck by the cleaning particles when rotating. In this embodiment, the outer contour of the cross section of the toggle rod 43 is configured as a triangle, and the radius difference between the circumscribed circle R and the inscribed circle r of the triangle is smaller than the radius of the cleaning particle K. The cross section of the toggle rod 43 is set as a triangle, which makes it easier to toggle the cleaning particles and prevents the toggle rod 43 from being stuck by the cleaning particles.

[0059] Furthermore, a transmission shaft 423 is fixed on the conveying disc 42, and a positioning hole 323 is provided on the bottom plate 32. The end of the transmission shaft 423 away from the conveying cavity 422 passes through the positioning hole 323 and enters the accommodating cavity 31, and is connected to the toggle rod 43. The conveying disc 42 and the bottom plate 32 can be positioned by the transmission shaft 423, and it is also convenient for the transmission shaft 423 to connect to the toggle rod 43 in the accommodating cavity 31, ensuring that the conveying of the cleaning particles is more reliable. The transmission shaft 423 can not only position the conveying disc 42, but also drive and connect the toggle rod 43, so that the distribution device has a more compact structure on the basis of realizing the function.

[0060] Of course, the transmission shaft 423 can be integrally arranged on the conveying disk 42, or can be separately arranged on the conveying disk 42. Preferably, in this embodiment, the transmission shaft 423 is integrally arranged on the conveying disk 42, so that the assembly complexity of the distribution device can be reduced and the reliability of the transmission can be improved.

[0061] In order to ensure that the cleaning particles can reliably reach the discharge port 321, the bottom plate 32 may include a bearing surface 352 for supporting the cleaning particles. The bearing surface 352 is constructed as a spiral surface, and the center line of the spiral surface is the center line of the discharge port 321. Along the height direction of the beverage machine, the portion of the bearing surface 352 away from the discharge port 321 is higher than the portion of the bearing surface 352 close to the discharge port 321, so that the spiral surface can guide the movement of the cleaning particles. Due to the effect of gravity, the cleaning particles can roll or slide to the discharge port 321 in an orderly manner under the guidance of the spiral surface. Compared with the bearing surface 352 constructed as a flat bottom surface, the bearing surface 352 constructed as a spiral surface can reliably transport the cleaning particles even when there are fewer remaining cleaning particles.

[0062] In particular, the bottom plate 32 includes a bottom plate 324 of the storage container 30 and a support plate 325 disposed above the bottom plate 324. The bearing surface 352 is disposed on the support plate 325. Along the radial direction of the spiral center line, the bearing surface 352 is disposed obliquely downward toward the center of the discharge port 321. The support plate 325 and the bottom plate 324 are disposed separately, and the support plate 325 can be manufactured separately. The shape and size of the support plate 325 are easier to ensure, and the structure and manufacturing of the storage container 30 itself are simplified, thereby reducing costs. In addition, the inclination of the bearing surface 352 can make the spiral surface form an oblique spiral surface, which can more reliably guide the cleaning particles to move toward the discharge port 321.

[0063] In this embodiment, the storage container 30 is constructed in a rectangular parallelepiped shape, and the center of the conveying disk 42 is concentrically arranged with the center of the rectangular parallelepiped; along the width direction of the rectangular parallelepiped, the discharge port 321 deviates from the center of the conveying disk 42; Figure 6 , along the axial direction of the spiral centerline, the height difference H from the highest point to the lowest point of the spiral surface is less than or equal to one pitch. The size setting of the spiral surface can more reasonably utilize the space in the storage container 30, and the amount of cleaning particles stored will not affect the reliable output of the cleaning particles.

[0064] Reference Figure 7 An elastic member 46 is arranged between the conveying disk 42 and the base 20. The elastic member can be a compression spring, and the two ends of the compression spring respectively abut the conveying disk 42 and the base 20. The elastic member 46 provides an elastic force for the conveying disk 42 to move away from the base 20 along the direction of the rotation axis, thereby increasing the rotation damping of the conveying disk 42 and reducing the rotation noise of the conveying disk 42, thereby achieving noise reduction and improving user experience.

[0065] Reference Figures 8 to 10 The conveyor disc 42 is connected to the bottom plate 32 by transmission, and the rotation of the conveyor disc 42 is converted into the movement of the bottom plate 32 in the radial direction of the conveyor disc 42 within a preset range based on the transmission connection. The movement of the bottom plate 32 can drive the cleaning particles in the accommodating chamber 31 to prevent the cleaning particles from being stuck in the process of moving to the discharge port 321, and the movement of the bottom plate 32 within the preset range can also prevent the cleaning particles from sticking. There are many ways to connect the conveyor disc 42 to the bottom plate 32, such as a reciprocating transmission connection based on a cam principle, a reciprocating transmission connection based on a crank connecting rod principle, etc.

[0066] The bottom plate 32 is connected with a reset element 34, and the conveyor disc 42 drives the bottom plate 32 to move in the first direction, and the reset element 34 provides a reset force in the opposite direction of the first direction to the bottom plate 32. Specifically, the bottom plate 32 can move to a first limit position in the first direction driven by the conveyor disc 42, and under the reset force of the reset element 34, the bottom plate 32 can perform a reset movement in the opposite direction of the first direction, from the first limit position to the second limit position; wherein the first limit position and the second limit position are two limit positions of the bottom plate 32 in the first direction; see Fig. 9 , Fig. 9 The arrow M direction in the figure can illustrate the first direction in this embodiment. The reset element 34 is provided so that the conveyor disc 42 only needs to drive the bottom plate 32 to move in one direction, while the movement of the bottom plate 32 in the opposite direction is driven by the reset element 34. The reset movement of the bottom plate 32 driven by the reset element 34 can generate greater vibration potential energy, and the effect of preventing the cleaning particles from getting stuck and sticking is better. The reset element 34 is constructed as a compression spring, and can also be other elements that can generate a reset force, such as repelling magnets.

[0067] In this embodiment, as mentioned above, the support plate 325 and the bottom plate 324 can be separated, that is, the support plate 325 can be set as a separate component independent of the storage container 30, the transmission shaft 423 passes through the bottom plate 324 and is connected to the support plate 325 in transmission, and there is a preset gap S between the support plate 325 and the side wall of the storage container 30, and the support plate 325 moves relative to the bottom plate 324 along the radial direction of the conveyor disc 42 within the preset gap S. The movement of the support plate 325 can be hidden inside the storage container 30, and the transmission shaft 423 only drives the support plate 325, which can reduce the transmission load. The reset element 34 can be set between the bottom plate 324 and the support plate 325, the first direction can be along the length direction of the storage container 30, and the preset gap S can be set larger, so as to increase the amplitude of the reciprocating movement of the support plate 325, and further avoid the cleaning particles from getting stuck or sticking.

[0068] Reference Fig. 9 and Fig.10Specifically, a matching groove 326 is provided on the support plate 325, and a driving tooth 426 is provided on the transmission shaft 423. The transmission shaft 423 and the matching groove 326 are matched along the radial clearance of the transmission shaft 423. A blocking portion 327 is formed in the matching groove 326. The blocking portion 327 interferes with the driving tooth 426 along the first direction. Driven by the transmission shaft 423, the driving tooth 426 moves toward the blocking portion 327 in the counterclockwise direction. After the driving tooth 426 contacts the blocking portion 327, the driving tooth 426 can drive the blocking portion 327 to move, so that the support plate 325 moves in the first direction. After the driving tooth 426 moves in the counterclockwise direction to pass over the blocking portion 327, that is, after the driving tooth 426 is disconnected from the blocking portion 327, the support plate 325 can be driven by the reset element 34 to perform a reset movement in the opposite direction of the first direction. Please refer to Fig. 9 , Fig. 9 The direction of the arrow R in the figure can be exemplified as the counterclockwise direction in this embodiment. The arrangement of the matching groove 326 and the driving tooth 426 can simplify the transmission connection between the transmission shaft 423 and the support plate 325, so that the structure of the dispensing device is compact and the cost is low. Fig. 9 , the transmission shaft 423 rotates in the direction of the arrow, the driving tooth 426 abuts against the blocking portion 327, and the support plate 325 has a preset gap with the bottom plate 324 in the first direction. The driving tooth 426 drives the support plate 325 to move in the first direction until Fig.10 As shown in , the driving tooth 426 passes over the blocking portion 327 in the direction of the arrow, and the support plate 325 is reset in the opposite direction of the first direction under the action of the reset element 34. Among them, one driving tooth 426 can be provided along the circumference of the transmission shaft 423, or multiple driving teeth 426 can be provided at intervals. In this embodiment, three driving teeth 426 are provided at intervals along the circumference of the transmission shaft 423. The transmission shaft 423 can push the support plate 325 three times when it rotates one circle. In this way, the frequency of the reciprocating vibration of the support plate 325 can be increased, thereby further preventing the cleaning particles from getting stuck or sticking.

[0069] Reference Figure 11 to Figure 13 In this embodiment, one conveying chamber 422 is provided, and the conveying disc 42 only conveys one cleaning particle per rotation. Along the moving direction of the conveying chamber 422, the conveying chamber 422 has a waiting position, a receiving position and an output position in sequence. In the waiting position, the conveying chamber 422 is staggered from the discharge port 321 and the delivery outlet 201. Fig.11 In the receiving position, the transfer chamber 422 is connected to the discharge port 321, and the transfer plate 42 is in a state of receiving particles, such as Fig.12 In the output position, the delivery chamber 422 is connected to the delivery outlet 201, and the delivery disk 42 is in the state of delivering particles, such as Fig.13When the conveyor disc 42 is in the standby state, the conveyor cavity 422 is staggered from the discharge port 321 and the delivery outlet 201, and the cleaning particles will not be contained in the conveyor cavity 422 for a long time, which can prevent the cleaning particles from being stuck in the conveyor cavity 422 due to moisture and cannot be discharged. In addition, when the conveyor disc 42 drives the conveyor cavity 422 to rotate, it also drives the toggle rod 43 to rotate, further ensuring that the cleaning particles can smoothly fall from the discharge port 321 into the conveyor cavity 422.

[0070] In other optional embodiments, multiple transmission chambers 422 may be provided, and the transmission disc 42 rotates one circle to realize the transmission of multiple cleaning particles. Along the movement direction of the transmission disc 42, each of the multiple transmission chambers 422 has a waiting position, a receiving position and an output position in sequence. When the transmission disc 42 is in the standby state, each transmission chamber 422 is staggered with the discharge port 321 and the delivery outlet 201.

[0071] In particular, the transfer chamber 422 also has a detection position, such as Fig.14 As shown, along the movement direction of the transmission cavity 422, the receiving position, the detection position and the output position are sequentially arranged, as shown in FIG. Fig.12 As shown, the delivery chamber 422 is located in the receiving position, such as Fig.14 As shown, the transfer chamber 422 is located at the detection position, such as Fig.13As shown, the transmission chamber 422 is located at the output position. The dispensing device also includes a first detection element 51 disposed on the base 20, and the first detection element 51 is used to detect the cleaning particles in the transmission chamber 422. The first detection element 51 is triggered when the transmission chamber 422 reaches the detection position, that is, the transmission chamber 422 is at the detection position, and the first detection element 51 is triggered. The first detection element 51 can be disposed above the transmission disk 42 to facilitate more accurate detection. Triggering the first detection element 51 when the transmission chamber 422 reaches the detection position can improve the accuracy of the detection, increase the service life of the first detection element 51 and be more energy-efficient. The first detection element 51 can be any sensor that can detect whether there are cleaning particles in the transmission chamber 422, such as an ultrasonic sensor, a photoelectric sensor, a pressure sensor, a micro switch, and the like. The base 20 includes a circuit board 55, which is fixedly connected to the bottom of the storage container 30, and a part of the circuit board 55 extends above the conveying disk 42. The first detection element 51 is fixed on the side of the circuit board 55 facing the conveying disk 42. When the conveying cavity 422 rotates to the detection position, the conveying cavity 422 is just located below the first detection element 51, so that the first detection element 51 can detect whether there are cleaning particles in the conveying cavity 422. Further, the dispensing device also includes a second detection element 52, which is arranged on the base 20, and the conveying disk 42 is provided with a sensing part 425 corresponding to the conveying cavity 422, and the second detection element 52 is used to detect the sensing part 425. When the second detection element 52 detects the sensing part 425, the dispensing device can determine that the conveying cavity 422 is in the detection position. The detection position can also be determined based on the waiting position or the receiving position, for example, by the rotation angle of the conveying disk 42, the running time of the motor 41, the disconnection of the signal after the sensing part 425 is detected for a predetermined time, and the signal of another sensing part 425 is detected. When it is determined that the transmission chamber 422 is in the detection position, the first detection element 51 can be triggered. It can be understood that the first detection element 51 is not detected in real time, but the detection action of the first detection element 51 is triggered when the dispensing device confirms that the transmission chamber 422 is in the detection position. In addition, if there are multiple transmission chambers 422, correspondingly, multiple sensing parts 425 need to be set up accordingly, and the transmission chambers 422 correspond to the sensing parts 425 one by one, that is, the number of transmission chambers 422 is consistent with the number of sensing parts 425, and each sensing part 425 is used to determine the position of the corresponding transmission chamber 422.

[0072] In this embodiment, the distribution device further includes a third detection element 53, which is also disposed on the base 20. The third detection element 53 and the second detection element 52 are spaced apart along the circumference of the conveyor disc 42. When the second detection element 52 detects the sensing portion 425, the distribution device can determine that the conveying chamber 422 is in the detection position. When the third detection element 53 detects the sensing portion 425, the distribution device can determine that the conveying chamber 422 is in the waiting position, or the waiting position can be determined based on the detection position. By detecting the sensing portion 425 respectively by two detection elements to determine the waiting position and the detection position, the detection is reliable and the control of the distribution device is simpler.

[0073] The second detection element 52 and the third detection element 53 are configured as micro switches, and the sensing part 425 is configured as a groove or a protrusion arranged on the circumference of the conveying disk 42. The detection signal can be a signal that the micro switch is triggered by contact with the protrusion, or a signal that the micro switch is disconnected when it corresponds to the groove. The matching structure of the micro switch and the sensing part 425 is simple, and the cost of the dispensing device can be reduced. In addition, the two micro switches are arranged on the base 20, and the structure is more compact. The second detection element 52 and the third detection element 53 can also be configured as a photoelectric sensor or a Hall sensor, etc., and the corresponding sensing part is set to a structure that can be sensed by the photoelectric sensor or the Hall sensor.
