Description

Technical Field

[0001] This invention relates to the field of beverage machines, and in particular to a feeding mechanism for preventing powder from becoming damp and clumping. Background Technology

[0002] Powder brewing equipment is a device that can automatically mix powder and liquid to form beverages. Its working principle is to mix and prepare a set amount of powder and liquid. Common powder brewing equipment includes soy milk makers, coffee machines, instant juice machines, etc. However, current powder brewing equipment has certain problems in practical applications.

[0003] Specifically, powder preparation equipment generally includes at least a powder storage container for storing the powder and a mixing container for mixing the powder and liquid. The powder and liquid in a predetermined ratio are added to the mixing container and thoroughly stirred. To improve the solubility of the powder and meet the user's demand for hot beverages, powder preparation equipment often uses hot water to prepare the powder. However, hot steam can easily enter the powder storage container during the powder transportation process, causing several problems: 1. It can cause the powder to become damp and clump together, clogging the powder outlet and affecting the accuracy and efficiency of the output. 2. It can cause contamination of the powder raw materials. Water vapor entering the powder storage container can make the powder storage environment humid, which may lead to bacterial growth.

[0004] In addition, the amount of powder dispensed per batch in current powder brewing equipment is difficult to control precisely, which in turn affects the taste of the brewed beverage. Summary of the Invention

[0005] The purpose of this invention is to provide a powder feeding mechanism that prevents powder from getting damp and clumping. This powder feeding mechanism can be applied in powder brewing equipment and has the effects of preventing powder from getting damp and clumping, accurately controlling the amount of powder discharged, and ensuring the taste and quality of beverages.

[0006] This solution provides a top-discharge pushing mechanism for preventing powder from becoming damp and clumping, comprising at least: a powder silo, a pushing component, a mixing silo, a powder feeding silo door, and a power component; wherein the powder silo and the mixing silo are spaced apart, the pushing component is placed inside the powder silo and pushes the powder from bottom to top, the powder feeding silo door is placed above the powder silo, and the power component drives the powder feeding silo door to change position between the closed position and the open position of the powder silo, and when the powder feeding silo door is in the closed position, the powder feeding silo door cover is placed at the opening of the powder silo.

[0007] Compared with the prior art, the present invention has the following characteristics and beneficial effects:

[0008] 1. Unlike the traditional powder discharge method, this solution uses an upward pushing method to output a fixed amount of powder. This method avoids the impact of the powder's own weight on the accuracy of the discharge amount. Furthermore, a stepper motor is used to control the forward stroke of the push rod to accurately control the discharge amount each time.

[0009] 2. The feeding direction of the feeding component is corrected by using the feeding power component, thereby accurately controlling the output amount and ensuring the flavor of the prepared beverage.

[0010] 3. The powder silo and the mixing silo are arranged in parallel. The feeding component on the powder silo moves toward the mixing silo, pushing the powder into the mixing silo while closing the silo door. A position detection switch is set on the control platform to detect whether the mixing silo lid is completely closed. After the mixing silo lid is completely closed, hot water is added to the mixing silo to prevent hot water vapor from evaporating into the powder silo and to prevent the powder in the powder silo from becoming damp and clumping.

[0011] 4. The mixing chamber is connected to a fan, which extracts heat from the mixing chamber to reduce the evaporation of hot water steam. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0022] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] As shown in the figure, the present invention provides an upper discharge pushing mechanism for preventing powder from getting damp and clumping. The upper discharge pushing mechanism includes at least: a powder silo (10), a pushing component (21), a mixing silo (80), a feeding powder silo door (41), and a power component. The powder silo (10) and the mixing silo (80) are arranged at intervals. The pushing component (21) is placed in the powder silo (10) and pushes the powder from bottom to top. The feeding powder silo door (41) is placed above the powder silo (10). The power component is connected to drive the feeding powder silo door (41) to change its position between the closed position and the open position of the powder silo. When the feeding powder silo door (41) is in the closed position, the feeding powder silo door (41) covers the opening of the powder silo (10).

[0025] Correspondingly, when the feeding powder hopper door (41) is in the powder hopper open position, the feeding powder hopper door (41) is away from the mixing hopper (80) and does not cover the opening of the powder hopper (10). In this way, when the feeding powder hopper door (41) changes from the powder hopper open position to the powder hopper closed position, the feeding powder hopper door (41) approaches the mixing hopper (80) and finally covers the opening of the powder hopper (10), and pushes the powder into the mixing hopper (80) while approaching the mixing hopper (80).

[0026] In this scheme, in order to achieve the technical effect of pushing the powder into the mixing chamber (80), the opening height of the mixing chamber (80) is not higher than the opening height of the powder chamber (10), and when the feeding powder chamber door (41) is in the closed position of the powder chamber, the edge of the feeding powder chamber door (41) is placed at the edge of the mixing chamber (80) or the feeding powder chamber door (41) partially covers the opening of the mixing chamber (80).

[0027] It is worth mentioning that in some embodiments, the feeding powder hopper door (41) and the mixing hopper door (61) are located on the same horizontal plane, which is beneficial for the conveying of powder. However, the mixing hopper door (61) and the feeding powder hopper door (41) are not located on the same horizontal plane.

[0028] Preferably, the opening height of the mixing chamber door (61) is lower than the opening height of the feeding powder chamber door (41). At this time, the mixing chamber (41) is provided with an opening groove corresponding to the side wall position of the mixing chamber door (61). The mixing chamber door (61) extends into the mixing chamber (41) from the position of the opening groove and covers the mixing chamber (41).

[0029] In addition, the upper discharge and pushing mechanism includes a mixing chamber door (61), wherein the mixing chamber door (61) is placed above the mixing chamber (80), and the power unit is connected to drive the mixing chamber door (61) to change its position between the mixing chamber closed position and the mixing chamber open state. When the mixing chamber door (61) is in the mixing chamber closed position, the mixing chamber door (61) covers the opening position of the mixing chamber (80).

[0030] In this scheme, the control is that the edge of the feeding powder hopper door (41) is placed at the edge of the mixing hopper (80) before the mixing hopper door (61) is placed at the opening of the mixing hopper (80). That is, the mixing hopper door (61) can be completely placed on the mixing hopper (80) only after the feeding powder hopper door (41) can pour all the powder into the mixing hopper (80).

[0031] The upper discharge and pushing mechanism includes at least an opening and closing sensor, wherein the opening and closing sensor is set between the displacement start and stop or the stroke of the mixing chamber door (61) and the feeding powder chamber door (41), and the sensor is at least one of the following: on / off switch, Hall magnetic sensor, color sensor, pressure sensor, distance sensor, ultrasonic sensor, light sensor, and proximity sensor.

[0032] In this embodiment, the upper discharge and pushing mechanism includes at least a closing sensor (71), wherein the closing sensor (71) is positioned such that when the mixing chamber door (61) is in the closed position, the mixing chamber door (61) touches the closing sensor (71) to trigger a mixing chamber closing signal. After the mixing chamber (80) receives the mixing chamber closing signal, hot water is added into the mixing chamber (80). Of course, the upper discharge and pushing mechanism may also include an opening sensor (72), wherein the opening sensor (72) is positioned such that when the mixing chamber door (61) is in the open position, the mixing chamber door (61) touches the opening sensor (72) to trigger a mixing chamber opening signal. The specific positions of the closing sensor (71) and the opening sensor (72) are not affected.

[0033] The sensor is at least one of the following: an on / off switch, a Hall magnetic sensor, a color sensor, or a pressure sensor.

[0034] It is worth mentioning that the material feeding mechanism of this solution includes a processing plate, which is a working component that communicates with sensors and various control elements. After receiving the sensing signal from the sensor, the control elements work.

[0035] In an embodiment of this solution, the power unit simultaneously controls the movement stroke of the feeding powder silo door (41) and the mixing silo door (61), or the power unit controls the movement stroke of the feeding powder silo door (41) and the mixing silo door (61) respectively. That is, the power unit controls at least one of the movement strokes of the feeding powder silo door (41) and the mixing silo door (61) respectively or in conjunction.

[0036] When the power components control the movement stroke of the feeding powder silo door (41) and the mixing silo door (61) respectively, a feeding silo opening sensor and a feeding silo closing sensor are set for the feeding powder silo door (41). The feeding silo opening sensor is set at the position where the feeding powder silo door (41) triggers the feeding silo opening sensor when the feeding powder silo door (41) is in the feeding powder silo opening position. Correspondingly, the feeding silo closing sensor is set at the position where the feeding powder silo door (41) triggers the feeding silo closing sensor when the feeding powder silo door (41) is in the feeding powder silo closing position.

[0037] When the power unit simultaneously controls the movement stroke of the feeding powder silo door (41) and the mixing silo door (61), the movement transmission method of the power unit is selected as at least one of gear, rack, belt, connecting rod, hydraulic rod, pneumatic rod, crankshaft, and push rod.

[0038] In a specific embodiment of this solution, the power transmission method is selected as gear transmission. In this case, the upper discharge pushing mechanism includes a first rack (51) connected to the powder feeding hopper door (41), a second rack (53) connected to the mixing hopper door (61), and a transmission gear (52) meshing with the first rack (51) and the second rack (53). The first rack (51) and the second rack (53) are positioned on opposite sides of the transmission gear (52) and move relative to each other. The first rack (51) and the second rack (53) respectively mesh with the transmission gear (52) to change positions.

[0039] Specifically, the first rack (51) and the second rack (53) are staggered, and the transmission gear (52) is positioned at the staggered position of the first rack (51) and the second rack (53), meshing with the first rack (51) and the second rack (53) respectively. When the transmission gear (52) rotates clockwise, the first rack (51) located on the left side of the transmission gear (52) moves to the right, and the second rack (53) located on the right side of the transmission gear (52) moves to the left.

[0040] In this scheme, in order to achieve the technical effect that the mixing chamber door (61) is not completely closed when the powder is pushed into the mixing chamber (80), at least one of the first rack (51) and the second rack (53) is provided with at least one control component (54), and the control component (54) and the tooth pattern are spaced a certain distance apart. The control component (54) includes an elastic element (542) fixed at one end of the first rack (51) and a pin (541) connected to the elastic element (542). A baffle is provided on the movement stroke of the first rack (51). The control component (54) is selected as an electronic position sensor. The position sensor is at least one of the following: on / off switch, Hall magnetic sensor, color sensor, pressure sensor, or electromagnet, motor, bimetallic strip, and airbag used for resetting engagement.

[0041] The baffle position setting conditions are as follows: When the feeding powder hopper door (41) is in the closed position, the ejector pin (541) abuts against the baffle. The length of the ejector pin (541) is designed such that when the mixing hopper door (61) is in the closed position, the transmission gear (52) still meshes with at least one tooth of the first rack (51). At this time, after the feeding powder hopper door (41) is in the closed position, the transmission gear (52) continues to rotate, the ejector pin (541) abuts against the baffle, and the baffle blocks the ejector pin (541) from continuing to advance, and also blocks the first rack (51) from continuing to advance.

[0042] In order to collect the powder that may exist during the feeding process, a slot is formed at the bottom of the feeding powder hopper door (41) and at the end of the powder hopper (10) away from the mixing hopper (80). At least one waste hopper (42) is placed in the slot. Excess powder that exists during the feeding process can be swept into the waste hopper (42), and the waste hopper (42) is designed as a drawer.

[0043] Other,

[0044] When the processing plate receives the signal to close the mixing chamber door, it controls the hot water to enter the mixing chamber (80). At this time, since both the mixing chamber (80) and the powder silo (10) are closed, the hot water steam will not cause the powder stored in the powder silo (10) to become damp and clump. The location of the water inlet can be selected from at least one of the following: located at any position on the mixing chamber (80) body, located independently of the mixing chamber (80) at the opening of the mixing chamber (80), or built into the mixing chamber door (61).

[0045] Additionally, a fan (92) is installed near the opening of the mixing chamber (80) to extract hot air from the mixing chamber (80) or the opening. Alternatively, the fan (92) can be connected to the air duct (91). When hot water enters the mixing chamber (80), the fan (92) is started to extract hot air from the mixing chamber (80) or the opening through the air duct (91).

[0046] The mixing chamber (80) is made of at least one of the following: a metal Teflon container, a Teflon injection molded container, or a Teflon composite material with added silver ions or zinc ions.

[0047] The powder discharge mechanism provided by this invention can realize bottom-up material pushing. Specifically, the powder discharge mechanism includes at least:

[0048] The powder silo (10), the pusher (21), and the pusher power unit (23) are provided. The pusher (21) is placed inside the powder silo (10). The output end of the pusher power unit (23) is connected to the pusher (21). The input end of the pusher power unit (23) is electrically connected to the control board or cloud. Under the action of the pusher power unit (23), the pusher (21) moves linearly along the axis of the powder silo (10) and pushes the powder placed on the powder silo (10) from bottom to top.

[0049] It is particularly worth mentioning that in this scheme, the powder discharge mechanism adopts an upward pushing method, thereby reducing the impact of the powder's own weight and the micro-vibration during operation on the powder compaction and output. At this time, the pusher (21) is placed at the bottom side of the powder silo (10), and the pusher power component (23) is connected to the bottom of the pusher (21). When the powder discharge mechanism needs to push the material outward, the pusher (21) moves in a straight line from bottom to top along the powder silo (10) under the action of the pusher power component (23).

[0050] The powder hopper (10) is a hollow structural component with a powder chamber inside. The powder is placed inside the powder chamber and pushed out by the pusher (21). In this design, the powder hopper (10) can be a hollow tubular body. Furthermore, the cross-sectional area of ​​the pusher (21) matches the cross-sectional area of ​​the powder chamber inside the powder hopper (10). When the powder hopper is a hollow tubular body, the cross-sectional area of ​​the pusher (21) is such that its diameter is not greater than the cross-sectional area of ​​the powder chamber, and the skirt or soft sealing ring is greater than the cross-sectional area of ​​the powder chamber. That is, it is preferable to control the pusher (21) to block the bottom of the powder hopper (10) to prevent the powder from flowing out from the gap.

[0051] To ensure that the pusher (21) can slide smoothly and stably within the powder hopper (10), the pusher (21) is a structural component with a certain thickness. Furthermore, the outer wall of the pusher (21) is provided with limiting strips (211), which are spaced apart along the axial direction of the pusher (21). The cross-sectional shape formed by the limiting strips (211) matches the cross-sectional shape of the powder chamber. Specifically, the limiting strips (211) of the pusher (21) are implemented as locking edges on the side of the pusher (21). When the pusher (21) moves within the powder hopper (10), the limiting strips (211) slide along the inner wall of the powder hopper (10). The setting of the limiting strips (211) can restrict the pusher (21) from swaying left and right or tilting during the pushing process.

[0052] In some embodiments, the circumferential surface of the pusher (21) is provided with a circumferential skirt (212) or a soft sealing ring. The cross-sectional area formed by the circumferential skirt (212) is larger than the cross-sectional area of ​​the powder chamber, and the circumferential skirt (212) is made of a deformable material. The circumferential skirt (212) protrudes upward and outward to surround the powder placed on the pusher surface. In this case, the circumferential skirt (212) can further prevent the powder from falling, and the circumferential skirt (212) also plays a sealing role during the entire pusher stroke of the pusher (21). Of course, in other embodiments, the pusher surface of the pusher (21) is provided with a soft sealing ring axially, wherein the structure and usage characteristics of the soft sealing ring are the same as those of the circumferential skirt (212).

[0053] The pushing power component (23) is connected to the pushing component (21) through the movable joint (22). At this time, the thrust of the pushing power component (23) is corrected by the movable joint, which plays the role of correcting the thrust that deviates from the axial direction. Since there are inevitably processing errors in the processing and technology of the powder discharge mechanism, the processing error causes the thrust given by the pushing power component (23) to the pushing component (21) and the axis of the powder bin (10) to be not on the same vertical line. Therefore, this solution uses the movable joint (22) to correct this part of the thrust. The movable joint (22) is limited to the bottom end of the pushing component (21) to correct the force in all directions into axial thrust.

[0054] Specifically, the movable joint (22) is a multi-directional movable component, which may be at least one of the following: ball joint, universal joint with at least two movable points, connector with at least two axes, flexible connector, coupling, convex-concave snap-fit ​​connector, and airbag.

[0055] In some embodiments, the output end of the pusher (23) directly or indirectly pushes the pusher (21) through at least one of a reduction gearbox, gear, pulley, screw, cam, screw sleeve, crankshaft, push rod, air bag, and guide rail.

[0056] In other embodiments, the pushing power component (23) directly or indirectly drives the powder hopper (10) to perform linear reciprocating motion relative to the pushing component (21) placed in the powder hopper (10). The powder hopper (10) is connected to the pushing power component (23) by at least one of the following methods: rack, gear, push rod, thread, flexible friction, lever, pull rod, belt, crankshaft. In this case, the pushing power component (23) directly acts on the pushing component (21).

[0057] In addition, the powder discharge mechanism of this solution further includes a pusher intermediate part (25), wherein the pusher intermediate part (25) is connected to the pusher part (21) through a movable joint (22), and the pusher screw (232) of the pusher power part (23) is placed inside the pusher intermediate part (25).

[0058] Specifically, the pusher intermediate part (25) is connected to the output shaft screw of the motor (323) through the nut (311), which converts the circular motion of the pusher power part (23) into linear motion, thereby controlling the reciprocating motion stroke of the pusher part to ensure that the output amount of the powder discharge mechanism is consistent each time.

[0059] Specifically, in this scheme, at least one of the first universal joint (221), the second universal joint (222), and the bearing connecting rod (223) is a movable joint (22), wherein the first universal joint (221) is connected to the pusher (21), the bearing connecting rod (223) is connected to the first universal joint (221) and the second universal joint (222), and the second universal joint (222) is connected to the pusher intermediate part (25), or the pusher intermediate part (25) is installed and connected through the second fixing part (242).

[0060] The first universal joint (221) is fitted into the first fixing member (241), and the bottom surface of the pusher member (21) forms a fixing groove that matches the first fixing member (241). The first fixing member (241) is fixed in the fixing groove. Similarly, the movable joint (22) and the pusher intermediate member (25) are connected and fixed by the second fixing member (242). Specifically, the second universal joint (222) is fitted into the second fixing member (242), and the top surface of the pusher intermediate member (25) forms a fixing groove that matches the second fixing member (242). The second fixing member (242) is fixed in the fixing groove.

[0061] In other words, a fixing groove is formed at the bottom of the pusher (21), and the first universal joint (221) is inserted into the first fixing member (241) and placed in the fixing groove. The first fixing member (241) and the fixing groove limit the first universal joint (221) to apply a thrust to the pusher (21) along the axial direction of the powder bin (10).

[0062] In this scheme, the pushing power component (23) includes a stepper motor (232), which is connected to the pushing screw (231). The stepper motor controls the stroke of the pushing screw (231) by stepping, thereby controlling the output of the powder discharge mechanism. The pushing screw (231) is placed inside the pushing intermediate component (25). In addition, in the implementation, the stepper motor can be implemented as a common brushed motor, a brushless motor, or a linear motor.

[0063] A limiting component is provided on the outer side of the pusher intermediate part (25), wherein the limiting component is fixed and remains stationary. Specifically, the limiting component includes at least a limiting protrusion (31) provided on the outer wall of the pusher intermediate part (25), wherein the limiting component remains stationary in a straight line direction during the rotation and upward movement of the pusher screw (231).

[0064] The limiting component is directly or indirectly assembled and fixed with at least one of the following components: the pushing power component (23), the limiting auxiliary component (32), the frame component, the appearance component, and the powder hopper (10).

[0065] For example, in one embodiment of this solution, the limiting component includes a limiting auxiliary member (32), wherein the limiting auxiliary member (32) is sleeved on one end of the pushing intermediate member (25), and the pushing intermediate member (25) is fixed to the limiting auxiliary member (32). Specifically, a limiting through hole is formed on the limiting auxiliary member (32), a limiting groove (321) is formed on the inner side of the limiting through hole, and a limiting protrusion (31) is formed on the outer side wall of the pushing intermediate member (25). The pushing intermediate member (25) passes through the limiting through hole, and at the same time, the limiting protrusion (31) is locked in the limiting groove (321) to play a fixing role. At this time, the lower fixing member (242) is locked in the groove formed on the top side of the limiting member (31), and the pushing intermediate member (25) is connected to the movable joint (22).

[0066] The limiting component forms a limiting relationship with at least one of the pusher (21) and the pusher intermediate (25) through at least one of the following methods: guide rail, groove, convex groove, linear bearing, roller, limiting post, and limiting ball. The limiting auxiliary component (32) forms a limiting relationship with the pusher screw (232) through at least one of the following methods: guide rail, groove, convex groove, linear bearing, roller, limiting post, and limiting ball.

[0067] Of course, in other embodiments, the limiting component or limiting auxiliary component (32) can be directly or indirectly fixed to the powder hopper, frame component or appearance component.

[0068] Additionally, position sensors can be directly or indirectly installed on at least one of the following: the powder hopper (10), the pusher (21), the pusher intermediate component (25), the pusher power component (23), or the rack, gear, push rod, thread, flexible friction, lever, tie rod, belt, or crankshaft that drives the powder hopper (10), the pusher (21), and the pusher intermediate component (25). By installing position sensors and cooperating with upper-level equipment, the position of the equipment components can be intelligently sensed, thereby controlling them.

[0069] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
