Description

Powdered beverage dispensing device

The technical field is as follows:

the utility model relates to a coffee, tea or similar beverage preparation device, in particular to a powdery or granular beverage dispensing device.

Background art:

with the advancement of social civilization and the increase in human physical life, the health impact of beverages has begun to be a widespread concern of society. The existing preparation type beverage is mostly in the form of powder and small granules. Because many beverages have rich fat content and are often microporous and light, the problems of 'shed material', unsmooth blanking and the like often occur in the ingredient process. The national Bureau 1995.06.07 authorizes and announces a novel practical patent of 'milk powder storage and taking tank', the patent scheme comprises a driving gear with a manual lever and a transmission device with a driven gear with a rotating shaft; a screw conveyor on the shaft; a control device having a pointer fixed to the manual lever and a dial centered on the manual lever; the bottom cover opening and closing device comprises a pressure lever, a pull rod, a small shaft for connecting the pull rod and a bottom cover, and a support sleeve of a support point, wherein a spring which can enable the bottom cover to be tightly closed on the discharge pipe opening can be used for the movement of the pressure lever. The technical scheme of the utility model has solved viscosity milk powder well and has appeared "canopy material", unloading technical problem such as not smooth easily. However, the product of the patent is specially designed for preparing milk powder, and the user object is a person who needs precise ingredients, so that the structure of the product is too complex when the product is used for preparing common ingredients such as coffee, granular tea leaves and the like, and especially, a metering device is redundant. Especially the technical proposal of the utility model is that a vertically arranged spiral feeder is adopted for feeding, and the material (milk powder) is utilized to open the bottom cover, thus the utility model is used for distributing the slippery beverage, once the bottom cover is opened, the control is lost, and the whole cylinder of beverage is poured and discharged completely.

The invention content is as follows:

the utility model aims to solve the technical problem of providing a distributing device suitable for various powdered or granular beverages.

The utility model provides a technical scheme of above-mentioned technical problem is:

a powdery beverage distributing device comprises a beverage cylinder for accommodating powdery beverages, and is characterized in that a flap valve is arranged on a discharge opening of the beverage cylinder, a multi-blade discharging wheel is arranged in a discharging hopper, and a transmission shaft of the discharging wheel is parallel to a transmission shaft of the flap valve; a push rod stretches across the lower parts of the unloading wheel and the transmission shaft head of the flap valve, a crank block mechanism is arranged between the push rod and the transmission shaft head of the flap valve, and a flat push type ratchet pawl mechanism is arranged between the push rod and the transmission shaft head of the unloading wheel; wherein,

the crank sliding block mechanism consists of a sliding block arranged at the head part of the push rod and a swing rod with a sliding groove and fixed at a transmission shaft head of the flap valve; the ratchet wheel and pawl mechanism consists of a ratchet wheel fixed on a transmission shaft head of the unloading wheel and a pawl hinged in the middle of the push rod, a torsion spring is further arranged on a pin hinged with the pawl, and two arms of the torsion spring respectively act on the push rod and the pawl;

a return spring is arranged between the push rod and the beverage cylinder.

A powdered beverage dispensing device, wherein the bladelike unloading wheel is formed by fixing a plurality of radial sheets on the transmission shaft of the unloading wheel.

Because the radial slab on the discharge wheel can stretch into powdered beverage, can forcedly rake the beverage downwards in the rotating process, can not produce shed materials, and especially the discharge wheel adopts the drive of ratchet and pawl mechanism, can artificially control the rotation angle of the discharge wheel through the motion amplitude of the control push rod, and achieves the purpose of controlling the discharge amount. In addition, when the shed material appears, the beverage in the beverage cylinder can be loosened by adopting a method of continuously changing the motion amplitude of the push rod.

Description of the drawings:

fig. 1, fig. 2 and fig. 3 are schematic structural views of an embodiment of the present invention, wherein fig. 1 is a front view, fig. 2 is a bottom view, and fig. 3 is a sectional view taken along a line a-a of fig. 2;

fig. 4 and 5 are schematic structural views of the unloading wheel in the embodiment shown in fig. 1-3, wherein fig. 4 is a front view, and fig. 5 is a right side view.

The specific implementation mode is as follows:

referring to fig. 1-3, the upper part of the beverage cylinder 1 is a cuboid, the lower part is an inverted quadrangular frustum pyramid-shaped discharge hopper 2 (see fig. 3) which is inclined to the left, the discharge wheel 3 is arranged in the discharge hopper 2 and is supported on the side wall of the discharge hopper 2 by a transmission shaft 8 in a penetrating way; the flap valve 5 is arranged on the discharge opening 4 and is arranged in a sleeve 7 on the upper side of the discharge opening 4 in a penetrating way by a transmission shaft 6; a guide sleeve 9 is arranged below the extending parts of the two

transmission shafts

6 and 8 on the side wall of the discharge hopper 2, and a push rod 10 is arranged in the guide sleeve in a penetrating way; the head of the transmission shaft 6 is provided with a crank 11, the tail end of the crank 11 is provided with a chute 11A, and the head of the push rod 10 is provided with a slide block 12 embedded in the chute 11 to form the crank-slide block mechanism; the head of the transmission shaft 8 is provided with a ratchet wheel 13, the middle part of the push rod 10 is provided with a pin 14, and the pin 14 is sleeved with a pawl 15 and a torsion spring 16 which acts on the push rod 10 and the pawl 15 respectively, so that the ratchet wheel and pawl mechanism is formed. The non-return claw 17 of the ratchet-pawl mechanism is fixed above the guide sleeve 9, and the claw tip of the non-return claw 17 is opposite to the claw tip of the pawl 15 (see fig. 1 and 2). The right end of the push rod 10 is folded towards the lower part of the discharge hopper 2 and is connected with a button 19 arranged on a support plate 18 extending downwards from the wall of the beverage cylinder 1, one end of an extension spring 20 is fixed at the bend of the push rod 10, and the other end is fixed on the support plate 18.

Referring to fig. 4 and 5 in combination with fig. 3, the discharging wheel 3 is blade-shaped and is formed by uniformly fixing four radial plates 3A in the axial direction of a transmission shaft 8 of the discharging wheel 3.

The working process of the present invention will be briefly described with reference to the accompanying drawings.

Referring to fig. 1-3, a button 19 is pressed to overcome the pulling force of an extension spring 20, a push rod 10 moves from left to right, a pawl 15 drives a ratchet wheel 13 to rotate clockwise, a discharging wheel 3 rotates synchronously to rake powdered beverages downwards from a beverage cylinder 1, and meanwhile the push rod 10 drives a crank 11 and a flap valve 5 to rotate clockwise through a slide block 12 at the head of the push rod to open a discharging opening 4 for discharging; after the external force on the button 19 is removed, the extension spring 20 pulls the push rod 10 to move left, and the push rod 10 drives the crank 11 and the flap valve 5 to rotate counterclockwise through the slide block 12 at the head part to close the discharge opening 4. In the process, the pawl 15 withdraws along the ratchet teeth of the ratchet wheel 13, and the discharging wheel 3 does not rotate. By repeating the above operation, the powdered beverage can be continuously dropped from the discharge opening 4. The operator can change the rotation angle of the discharging wheel 3 and the opening of the flap valve 5 by controlling the movement amplitude of the button 19, so as to achieve the purpose of adjusting the discharging amount. The button 19 can be pressed quickly and repeatedly in a small range to play a role in loosening the powdery beverage in the beverage cylinder 1, so that the effect of breaking arches is achieved.
