DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0041] According to the first aspect of the present application, a quantitative feeding device is provided, which can realize the quantitative feeding of bulk materials such as powdered materials (such as coffee powder, milk powder), bean ingredients (such as coffee beans, peanuts, soybeans, peppercorns), and granular ingredients (peanut crumbs, biscuit crumbs, sugar grains).

[0042] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , respectively show the structural schematic diagram and cross-sectional view of the quantitative feeding device 100 in different states and different viewing angles. The quantitative feeding device 100 comprises a base 110, a movable part 120, a cover 130 and a stopper 140. The base 110 serves as the installation base for the movable part 120, the cover 130 and the stopper 140. The movable part 120, the cover 130 and the stopper 140 are either fixedly or movably installed on the base 110. At least one of the base 110 and the movable part 120 is provided with a quantitative chamber 101, which may be provided in the base 110, or provided in the movable part 120, or both of the base 110 and the movable part 120 are provided with cavities, and the cavities of the two communicate with each other to merge to form the quantitative chamber 101. The quantitative chamber 101 has a feed end 102 and a discharge end 103. The feed end 102 is used for feeding materials into the quantitative chamber 101, and the discharge end 103 is used for discharging materials from the quantitative chamber 101. The volume of the quantitative chamber 101 is set to the volume of ingredients required for food processing.

[0043] The cover 130 and the movable plate 141 of the stopper 140 are respectively disposed at the feed end 102 and the discharge end 103 of the quantitative chamber 101, see Figure 3 and Figure 7The cover 130 is movably disposed on the base 110 to open or close the feed end 102 of the quantitative chamber 101; the stopper 140 is disposed on the base 110, and the stopper 140 includes a movable plate 141 movably disposed on the base 110, and the movable plate 141 is used to open or close the discharge end 103 of the quantitative chamber 101. Figure 3 and Figure 7 The movable member 120 is movably disposed on the base 110, and the movable member 120 can be movable relative to the base 110 in the form of fixed-axis rotation, movement or swing. When the cover 130 closes the feed end 102 of the quantitative chamber 101, the cover 130 acts on the movable plate 141 through the movable member 120 to drive the movable plate 141 to move, thereby opening the discharge end 103 of the quantitative chamber 101, so that the material filled in the quantitative chamber 101 falls.

[0044] When loading, if Figure 1 and Figure 3 As shown, the cover 130 opens the feed end 102 of the quantitative chamber 101, and the movable plate 141 closes the discharge end 103 of the quantitative chamber 101. At this time, the quantitative chamber 101 forms a slot structure with an upper opening. The user can add materials into the quantitative chamber 101 through the feed end 102 until the quantitative chamber 101 is full. Figure 5 and Figure 7 As shown, the cover 130 closes the feed end 102 of the quantitative chamber 101, and the movable plate 141 opens the discharge end 103 of the quantitative chamber 101. At this time, the quantitative chamber 101 forms a funnel 150 structure with an opening at the bottom, and the material in the quantitative chamber 101 falls through the discharge end 103.

[0045] When the quantitative feeding device 100 is in use, the user only needs to fill the quantitative chamber 101 and close the cover 130 to achieve quantitative feeding, which is convenient to use. Since the opening of the movable plate 141 is performed along with the closing of the feed end 102 of the quantitative chamber 101 by the cover 130, when an excessive amount of material is loaded into the quantitative chamber 101, the excess material overflows and the cover 130 cannot close the feed end 102 of the quantitative chamber 101. At this time, the movable plate 141 is not disturbed and maintains the state of closing the discharge end 103 of the quantitative chamber 101. This ensures that no excessive material will enter the interior of the machine, thereby reducing the problem of materials entering the interior of the machine and getting stuck or blocking the operation of the equipment, and reducing the problem of materials getting moldy after entering the interior of the machine.

[0046] The specific process of the cover 130 acting on the movable part 120 may be that the cover 130 continuously acts on the movable part 120 during the gradual closing process, or that the cover 130 acts on the movable part 120 only after it moves to a certain position during the closing process. In some embodiments, the cover 130 may act on the movable part 120 only when it closes the feed end 102 of the quantitative chamber 101. The specific manner in which the cover 130 acts on the movable part 120 may be that the cover 130 and the movable part 120 are in mechanical contact or mechanical connection to transmit the force, or that the cover 130 triggers an electrical signal during the movement process, and the movable part 120 moves under the external force after the electrical signal is triggered. The specific process and specific manner in which the movable part 120 acts on the movable plate 141 can refer to the specific process and specific manner in which the cover 130 acts on the movable part 120 in the above text, and will not be repeated here.

[0047] The cover 130 is movably mounted on the base 110, and specifically, the cover 130 is rotatably mounted on the base 110, or the cover 130 is a detachable lid. The movable plate 141 is movably mounted on the base 110, and specifically, the movable plate 141 is rotatably mounted on the base 110, or the movable plate 141 is slidably mounted on the base 110. This application does not limit this.

[0048] See also Figure 3 and Figure 7 In some embodiments, the movable plate 141 is rotatably mounted on the base 110. When the cover 130 closes the feed end 102 of the quantitative chamber 101, the cover 130 applies a force toward the discharge direction to the movable plate 141 through the movable part 120, so that the movable part 120 rotates in the discharge direction around the rotation axis, thereby opening the discharge end 103 of the quantitative chamber 101.

[0049] The movable plate 141 can rotate around its own axis or around an axis of an external device. In some embodiments, the movable plate 141 is a whole plate, and the movable plate 141 rotates around its symmetry axis. The cover 130 applies a force toward the discharge direction to the circumference of the movable plate 141 through the movable member 120, and the movable plate 141 flips. Figure 3 and Figure 7 There are two movable plates 141, and the two movable plates 141 are symmetrically distributed. When the cross section of the quantitative chamber 101 is circular, the two movable plates 141 are correspondingly semicircular. To facilitate the installation of the movable plates 141, in some embodiments, refer to Figure 3 and Figure 7 The stopper 140 further includes a rotating pin 143 mounted on the base 110 , and the movable plate 141 is rotatably mounted on the rotating pin 143 , and the axis of the rotating pin 143 can coincide with the symmetry axis of the cross section of the quantitative cabin 101 .

[0050] In some embodiments, the blocking member 140 also includes a reset member 142 acting on the movable plate 141. When the cover 130 opens the feed end 102 of the quantitative chamber 101, the movable plate 141 closes the discharge end 103 of the quantitative chamber 101 under the action of the reset member 142. The force applied by the reset member 142 to the movable plate 141 can resist the weight of the movable plate 141 and the weight of the material in the quantitative chamber 101, so that when the cover 130 does not act on the movable member 120, the movable plate 141 maintains the closure of the discharge end 103 of the quantitative chamber 101.

[0051] The reset element 142 may be a spring, a torsion spring, a spring, etc. Figure 4 In some embodiments, the reset member 142 is a torsion spring, which is sleeved on the rotating pin 143, and the two movable plates 141 are symmetrically installed on the rotating pin 143. The two torsion arms of the torsion spring act on the two movable plates 141 respectively. The torsion spring is located below the two movable plates 141 and is covered by the two movable plates 141, so that the material will not enter the installation position of the torsion spring.

[0052] See also Figure 1 and Figure 7 In some embodiments, a ridge 122 is provided in the quantitative chamber 101, and the ridge 122 separates the discharge end 103 of the quantitative chamber 101 into two discharge ports, and the two discharge ports correspond to the positions of the two movable plates 141 respectively. In the discharge direction, the ridge 122 covers the top of the rotating pin 143. On the one hand, the rotating pin 143 is located in the area covered by the ridge 122, which can prevent the material in the quantitative chamber 101 from entering the gap between the rotating pin 143 and the movable plate 141 and between the rotating pin 143 and the torsion spring; on the other hand, the upper surface of the ridge 122 is an inclined surface, which can play a certain guiding role for the material.

[0053] See also Figure 1 and Figure 7 In some embodiments, the ridge 122 is provided on the movable member 120, and the movable member 120 acts on the movable plate 141 through the ridge 122. When the cover 130 closes the feed end 102 of the quantitative chamber 101, the ridge 122 acts on the movable plate 141, so that the movable plate 141 opens the discharge end 103 of the quantitative chamber 101. In addition to the effects of the first and second aspects mentioned above, the ridge 122 can also allow the movable plate 141 to at least partially extend into the cavity formed by the ridge 122 when pushing the movable plate 141 to flip in the discharge direction, so as to prevent the falling materials from entering the gap between the rotating pin 143 and the movable plate 141 and between the rotating pin 143 and the torsion spring.

[0054] In some embodiments, the movable member 120 may also be a push rod, which acts on a position of the movable member 120 away from its rotation axis. Figure 3 and Figure 7 In some embodiments, the movable member 120 is a metering cylinder 121 movably disposed in the base 110, the inner cavity of the metering cylinder 121 forms the metering chamber 101, and the cover 130 can directly act on the cylinder wall of the metering cylinder 121. Figure 1 In some embodiments, the inner wall of the metering cylinder 121 is provided with a convex portion 123, and when the cover 130 closes the feed end 102 of the metering chamber 101, the cover 130 acts on the convex portion 123. In some embodiments, the inner wall of the metering cylinder 121 is provided with the above-mentioned ridge 122, and the cover 130 can also act on the ridge 122. In some embodiments, the inner wall of the metering cylinder 121 is provided with the above-mentioned ridge 122 and the above-mentioned convex portion 123, and the convex portion 123 is located at both ends of the ridge 122, such as Figure 1 In some embodiments, the movable member 120 is a plastic member, which is integrally injection molded.

[0055] See also Figure 3 and Figure 7 In some embodiments, the cover 130 includes a connected cover body 131 and an action portion 132, the cover body 131 is rotatably mounted on the base 110, and the cover body 131 covers the feed end 102 of the quantitative chamber 101. The action portion 132 protrudes from the surface of the cover body 131 toward the quantitative chamber 101, so that the action portion 132 can extend into the quantitative chamber 101. In some embodiments, the cover body 131 can include a cover plate and a surrounding edge located at the periphery of the cover plate, so that the cover plate is groove-shaped as a whole and can be buckled on the feed end 102 of the quantitative chamber 101. In some embodiments, the movable member 120 is a quantitative cylinder 121 movably disposed in the base 110, and the cover body 131 covers the top of the quantitative cylinder 121.

[0056] See also Figure 3 , Figure 6 and Figure 7 In some embodiments, the cover 130 is provided with a plurality of vents 134, which are distributed in the middle area of ​​the cover 130, so that when the cover 130 is placed on the feed end 102 of the quantitative chamber 101, the inner cavity of the quantitative chamber 101 can be connected to the outside through the vents 134, ensuring that the inner cavity of the quantitative chamber 101 has the same pressure as the outside. In addition, when the user adds materials to the quantitative chamber 101, the materials are usually piled up in a state of convexity in the middle (the quantitative chamber 101 can be filled after the materials are flattened), and the convex part in the middle of the materials may block the closing of the cover 130. By providing the vents 134, the convex part in the middle of the materials can enter the vents 134 and will not hinder the closing of the cover 130.

[0057] The base 110 serves as the installation base for the movable part 120, the cover 130 and the stopper 140. The base 110 may be an independent structural part, or the host of the device equipped with the quantitative feeding device 100 may be used as the base 110. This application does not limit this. Figure 3 and Figure 7 In some embodiments, the base 110 includes a main body 111 and a cylinder 112 connected to the main body 111, and the cover 130 is installed on the main body 111. The main body 111 or the cylinder 112 is provided with a stop groove 116, the stop groove 116 is annular, and the opening faces the discharging direction. The quantitative cylinder 121 extends into the stop groove 116 and is at least partially embedded in the cylinder 112. The quantitative cylinder 121 can move along the axial direction of the cylinder 112. The groove depth of the stop groove 116 is not less than the displacement of the quantitative cylinder 121, ensuring that the entrance of the quantitative cylinder 121 is always located in the stop groove 116 during the axial movement of the quantitative cylinder 121 along the cylinder 112. On the one hand, the stop groove 116 guides the movement of the quantitative cylinder 121, and on the other hand, the inner groove wall of the stop groove 116 guides the material. In some embodiments, the depth of the stop groove 116 is greater than the maximum displacement of the metering cylinder 121 , thereby ensuring that the material does not enter the gap between the metering cylinder 121 and the stop groove 116 .

[0058] In some embodiments, the length of the cylinder 112 is greater than that of the metering cylinder 121, so that the cylinder 112 guides the movement of the metering cylinder 121. In addition, the longer cylinder 112 can also provide a material channel that is directly connected to the food processing chamber (such as the coffee brewing chamber) of the device. Figure 3 and Figure 7 A funnel 150 is provided under the cylinder 112. The large end of the funnel 150 is detachably connected to the cylinder 112, and the small end of the funnel 150 is connected to the food processing chamber of the device (such as a coffee brewing chamber), so that the cylinder 112 and the food processing chamber of the device can be conveniently connected through the funnel 150 to match openings of different sizes.

[0059] See also Figure 3 and Figure 7 In some embodiments, a positioning structure 117 for limiting the rotation of the metering cylinder 121 is provided on the wall of the cylinder body 112. The positioning structure 117 can be a boss or a slide groove, so that the metering cylinder 121 can only move axially relative to the cylinder body 112 without relative rotation, thereby ensuring that the cover 130 can act on the metering cylinder 121 and the metering cylinder 121 can act on the movable plate 141.

[0060] See also Figure 1 and Figure 5In some embodiments, the quantitative feeding device 100 is applied to a coffee machine, which can add coffee beans and coffee powder at the same time. The bean bin 113 of the coffee machine is used as the main body 111 of the base 110. The bean bin 113 is provided with a bean inlet 115 and a powder inlet 114. The bean inlet 115 is used to add coffee beans, and the powder inlet 114 is used to add coffee powder or milk powder. The upper opening of the cylinder 112 is connected to the powder inlet 114, and the cover 130 is rotatably installed on the bean bin 113, and is used to open or close the powder inlet 114. The powder inlet 114 constitutes the feeding end 102 of the quantitative chamber 101. In some embodiments, the powder inlet 114 is provided with the above-mentioned stop groove 116.

[0061] In some embodiments, the bean bin 113 is a plastic part, which is integrally injection molded. The bean bin 113, the cylinder 112 and the funnel 150 are detachably connected in sequence for easy cleaning. In some embodiments, the base 110 can be integrally injection molded with a plastic part, and the movable part 120, the cover 130 and the stopper 140 can be detachably mounted on the base 110. Of course, in other embodiments, the base 110 can also have different configurations, which are not exhaustive here.

[0062] In some embodiments, the base 110 and / or the cover 130 are provided with a buckle structure for locking the cover 130 when the cover 130 closes the feed end 102 of the quantitative chamber 101. The buckle structure can adopt any embodiment disclosed in the prior art, such as a buckle hook and a buckle position 133, a buckle reset by a torsion spring, a matching lock pin and a lock hole, etc. Figure 1 and Figure 5 In some embodiments, the snap-fit ​​structure includes a snap-fitting hook (not shown in the figure) and a snap position 133. The hook is provided on the base 110, and the snap position 133 is provided on the cover 130. The snap position 133 is an inwardly recessed arc-shaped groove, and the hook is provided with an arc-shaped protrusion, so that the user only needs to apply light force to open the cover 130. Without the application of external force, the cover 130 can stably close the feed end 102 of the quantitative chamber 101.

[0063] In some embodiments, one of the base 110 and the cover 130 is provided with a first detection member 160, and the other is provided with a second detection member 170 coupled with the first detection member 160. When the cover 130 closes the feed end 102 of the quantitative chamber 101, the first detection member 160 is coupled with the second detection member 170. The electrical signal fed back by the first detection member 160 and / or the second detection member 170 can identify the position of the cover 130 relative to the feed end 102 of the quantitative chamber 101, and determine whether the cover 130 closes the feed end 102 of the quantitative chamber 101. The coupling mode of the first detection member 160 and the second detection member 170 can be photoelectric coupling, magnetic coupling, etc., which is not limited in this application. By providing the first detection member 160 and the second detection member 170, an electric control feedback will be generated when the user opens or closes the cover 130, which facilitates the electric control feedback of opening or closing the cover 130 to be involved in the control process of the entire device, for example, when the cover 130 is opened, the device stops working.

[0064] See also Figure 1 and Figure 4 In some embodiments, the first detection member 160 and the second detection member 170 are magnetically coupled. For example, the first detection member 160 may be a magnet, which is encapsulated in a box and disposed on the cover 130, and may be mounted on the outer surface or the inner surface of the cover 130; the second detection member 170 may be a reed switch, which is disposed on the base 110, and may be located on the upper surface or the lower surface of the base 110. Figure 1 and Figure 4 In some embodiments, the magnet is encapsulated in a box body and is disposed on the lower surface of the cover 130, close to the feed end 102 of the quantitative chamber 101. The reed switch is disposed on the lower surface of the base 110, also close to the feed end 102 of the quantitative chamber 101, and along the axial direction of the quantitative chamber 101, the projections of the magnet and the reed switch overlap to improve the coupling sensitivity.

[0065] In a second aspect of the present application, a food processing device is provided, which may be a coffee machine, a milk tea machine or a milk frother.

Taking a coffee machine as an example, the amount of coffee powder required to prepare coffee drinks of the same volume but different types (such as latte, cappuccino, standard American) is different. Quantitative chambers 101 of different volumes can be set, for example, quantitative cylinders 121 of different depths can be set. By replacing different quantitative cylinders 121, ordinary consumers can also make standard coffee drinks. In addition, in some embodiments of the first aspect above, by providing a ridge 122 and a stop groove 116, the entry of coffee powder into the gap inside the equipment can be reduced, the frequency of users cleaning the equipment can be reduced, and the user experience is better.

[0067] In a third aspect of the present application, a grinding coffee machine is provided, which includes a brewing chamber, a grinding device and a quantitative feeding device 100 according to any embodiment of the first aspect. The base 110 of the quantitative feeding device 100 is provided with a bean bin 113. The base 110 may be the bean bin 113 as a whole, or the bean bin 113 may be a part of the base 110.

The bean bin 113 is provided with a bean inlet 115 and a powder inlet 114. The bean inlet 115 is used to add coffee beans, and the powder inlet 114 is used to add coffee powder or milk powder. The upper opening of the cylinder 112 is connected to the powder inlet 114. The inner cavity of the cylinder 112 can be used as a quantitative chamber 101. In some embodiments, a movable quantitative cylinder 121 can be provided in the cylinder 112. The inner cavity of the quantitative cylinder 121 forms the quantitative chamber 101. The cover 130 can directly act on the cylinder wall of the quantitative cylinder 121. The cover 130 is rotatably mounted on the bean bin 113 and is used to open or close the powder inlet 114. The powder inlet 114 constitutes the feeding end 102 of the quantitative chamber 101. The bean bin 113 is connected to the inlet of the grinding device through the bean inlet 115. The bean bin 113 and the grinding device can be directly connected or connected through a bean lowering channel.

[0070] Since the bean bin 113 is provided with both a bean inlet 115 and a powder inlet 114, the user can choose to add coffee powder or coffee beans according to his / her own situation, and of course, can also add coffee powder and coffee beans at the same time. For example, when the remaining coffee beans and coffee powder are not enough to prepare a cup of standard coffee, the user can add coffee powder and coffee beans at the same time. The user can also add other powders such as milk powder and cocoa powder through the quantitative feeding device 100 to make a homemade flavored coffee drink. The grinding coffee machine provides users with a variety of usage scenarios to improve user experience.
