Description

Grinding device

Technical Field

The present disclosure relates to a grinder, and more particularly, to a grinder capable of performing a full washing operation on the remaining components after an electric driving device is separately separated.

Background

Many of the cases of using powdery or granular food materials, for example, spices or drinks such as pepper powder and curry powder …, are aimed at making granular or flaky solids into powder after grinding, and making the powdery or granular food materials easily dissolved and uniformly dispersed in foods or liquids.

Conventional grinders exist in two types, for example, manual or electric grinders, in which the granular or flaky food material is put into use and then directly ground into powder in a manual or electric manner to be directly sprinkled into food or soup, "ready-to-use" which is popular with eaters or cooks. Taiwan patent publication nos. 367805 and 415215 (corresponding to us 5,865,344) owned by the present applicant disclose an electric and manual grinder, respectively, in which an object to be ground, such as pepper granules, is accommodated in a hollow housing, and a driving device, such as an electric power device or a manual rotary base, is coupled to the upper portion of the housing. Therefore, it is very inconvenient to remove the driving device before adding the object to be ground into the housing.

If the material to be ground is coffee bean, the particles are large and the baked material is hard, so that the conventional manual bean grinder, for example, is prone to fatigue of the wrist and arm when grinding the powder to a proper brewing amount manually. The manual bean grinder has the advantages that the coffee beans are ground in a slow grinding (low rotating speed) mode, so that the oxidation speed of powder can be reduced, and the coffee after brewing has strong aroma and mellow feeling.

Therefore, most of the existing bean grinders mainly use electric bean grinders, which have the advantages of high grinding speed and capability of brewing coffee in real time. The disadvantage of the electric bean grinder is that it grinds coffee beans at a speed of at least approximately thousands of revolutions per minute (high rotational speed), and during this grinding process, the grinding disc and the grinding base of the grinding device transmit the high temperature during operation to the coffee beans, so that the ground powder is oxidized at an accelerated rate due to the temperature rise, and loses the natural aroma.

In particular, the electric driving device of the electric bean grinder is arranged in the machine body, the grinding disc and the poking sheet are fixedly connected to the output shaft of the electric driving device, and the grinding seat is fixedly arranged in the machine body, such as the bottom of the storage container, and is difficult to disassemble. Because the coffee beans have grease, the coffee beans are easy to stick to the grinding disc, the grinding seat and the poking sheet after being ground into powder, and although a user can clean the coffee beans by using a brush, the user can only brush off local areas of the grinding disc, the grinding seat and the poking sheet, so that the adhered powder is difficult to remove comprehensively. In particular, the gap between the grinding disc and the grinding seat is a dead angle where the brush cannot be cleaned, so that the sticky powder is oxidized, often generating peculiar smell and generating sanitary problems, which are unpleasant for consumers and are a drawback to be improved urgently.

Detailed Description

As shown in fig. 1 to 5, basically, the grinder of the present disclosure includes a container 1, an electric driving device 2, and a base 3.

Referring to fig. 1, 2 and 5, the container 1 is a hollow base, and a partition 11 is radially disposed inside the hollow base so as to be axially partitioned into a storage space 12 for storing the object to be ground and a device space 13 for installing the electric driving device 2. The storage space 12 is preferably transparent so as to facilitate the observation of the quantity of the material to be ground, such as coffee beans. A connecting ring 121 having a feeding opening 122 extends axially from the bottom of the storage container 1, and at least two hooks 123 (shown in fig. 2 and 5) radially extend from the peripheral surface of the bottom of the storage container 1 so as to be inserted into and fastened to at least two corresponding fastening slots 311 of the base 3, so that the storage container 1 and the base 3 can be combined or separated.

The storage space 12 and the device space 13 are respectively a housing, and the housing is connected to each other and then passes through the storage space 12 by a connecting member, such as a screw, and is locked to the bottom surface of the device space 13. In which the bottom of the device space 13 is opened with a through hole 131 (shown in fig. 2 and 5) aligned with the material inlet 122.

In order to provide the grinding function, in a first embodiment of the present disclosure, a hollow grinding seat 14 is installed in the feeding hole 122, and a fixing ring 15 is combined, for example, screwed to the connecting ring 121, so that the grinding seat 14 is fixed in the feeding hole 122. That is, the grinding base 14 and the fixing ring 15 can be detached from the feeding opening 122 and the connecting ring 15 respectively for cleaning.

In order to provide the grinding and powder particle size adjusting functions, in a second embodiment of the present disclosure, a lifting ring 16 is connected, for example, screwed to an inner circumferential surface of a bottom of a funnel-shaped adjusting ring 17, and then the adjusting ring 17 is abutted to the bottom of the storage container 1, so that the hooks 123 pass through at least two grooves 171 preset on the top surface of the adjusting ring 17. In order to make the lifting ring 16 only move axially in the material inlet 122, a guiding mechanism is disposed therebetween, and the guiding mechanism includes a plurality of guiding grooves 161 and a plurality of guiding columns 125 disposed on the outer peripheral surface of the top of the lifting ring 16 and the inner peripheral surface of an inner flange 124 of the bottom surface of the material inlet 122, which are opposite to each other and are sleeved with each other.

Then, after an elastic body 181, such as a spring, is sleeved on the bottom of a material guiding ring 18, the bottom of the material guiding ring 18 is extended from the bottom of the material inlet 122 and connected thereto, such as screwed to the inner circumferential surface of the top of the lifting ring 16, so that the elastic body 181 is interposed between the material guiding ring 18 and the inner flange 124, and the material guiding ring 18 has an axial elastic displacement function.

Finally, the grinding seat 14 is sleeved in the lifting ring 16, and the fixing ring 15 is connected, for example, screwed to the outer peripheral surface of the bottom of the lifting ring 16, so that the grinding seat 14 is fixedly arranged in the lifting ring 16. That is, the grinding base 14 and the fixing ring 15 can be detached from the lifting ring 16 and the connecting ring 15, respectively, for cleaning. The top of the adjusting ring 17 is provided with a rotating ring 172 abutting the bottom surface of the object container 1, and the abutting surfaces of the object container 1 and the rotating ring 172 are provided with a fixed toothed ring 126 and a movable toothed ring 173 (shown in fig. 5) which are engaged with each other. Therefore, when the user rotates the rotating ring 172, the lifting ring 16 connected to the bottom thereof can only axially displace along the inner circumferential surface of the bottom of the adjusting ring 17 by the guiding action of the guiding slot 161 and the guiding column 125 of the material inlet 122, and synchronously drives the grinding base 14, the fixing ring 15 and the material guiding ring 18 to axially lift and displace, thereby forming an interlocking relationship.

The bottom of the grinding base 14 has a large-sized rim 141 abutting against the fixed ring 15, and a grinding cylinder 142 with a smaller outer diameter is above the rim 141. In the first embodiment of the grinding base 14, the outer peripheral surface of the grinding cylinder 142 is provided with a plurality of positioning slots 143 so as to be installed in the material inlet 122 and inserted by a plurality of positioning pillars (not shown) correspondingly installed, so that the grinding base 14 is fixed in the material inlet 122 without rotating. In the second embodiment of the grinding base 14, the outer peripheral surface of the grinding cylinder 142 is provided with a plurality of positioning slots 143 so as to be installed in the lifting ring 16 and inserted by a plurality of positioning posts 162 correspondingly installed, so that the grinding base 14 is fixed in the lifting ring 16 without rotating. In addition, a plurality of inclined guide ribs 144 are annularly arranged on the upper portion of the inner peripheral surface of the grinding cylinder 142, and a plurality of grinding teeth 145 in a form of thick oblique teeth are annularly arranged on the lower portion.

Therefore, in the second embodiment of the storage container 1, after the hook 123 at the bottom passes through the seat 171 on the top surface of the adjusting ring 17, the storage container 1 is inserted into and fastened to the hook slot 311 of the base 3, so that the storage container 1 and the base 3 can be combined or separated.

The electric driving device 2 is modularly designed as a unit body provided with a power switch 22 coupled to a power input socket 21 and an electric motor, such as a dc motor (not shown), and a speed reducing mechanism (not shown) driven by the electric motor, an output shaft 23 (shown in fig. 5) of the speed reducing mechanism being located in the through hole 131. Therefore, when the power input socket 21 receives power, the motor is operated by switching the power switch 22, the speed is reduced by the speed reduction mechanism, and the reduced power is output from the output shaft 23. The rotational speed of the output shaft 23 is measured between 70 and 90 revolutions per minute, preferably 80 revolutions per minute. Therefore, the electric driving device 2 can obtain a slow grinding effect at a low rotation speed, so as to reduce the condition of accelerated oxidation caused by ground objects, such as coffee powder, in the grinding process.

The power input socket 21 is disposed on the outer side of the electric driving device 2, and a through hole 132 is formed in the device space 13 corresponding to the power input socket 21. Furthermore, the power socket 21 can be plugged with a power output plug of a household or vehicle power converter to obtain power. That is, the grinder can be used indoors, and can obtain power from an automobile or a locomotive through a vehicle power converter when the grinder is located outdoors, so that the application range is expanded. In addition, the power switch 22 is preferably disposed on the top surface of the electric driving device 2 for the convenience of operation of the user.

In particular, the partition 11 has an arc protrusion 111 in the center, so that the device space 13 and the electric driving device 2 are shaped like mushrooms without causing erroneous insertion. In order to prevent the electric driving device 2 from axially falling out of the device space 13, a connecting column 25 is further disposed on the output shaft 23 of the electric driving device 2, that is, the connecting column 25 covers the pivot shaft 23. Wherein at least one tenon 251 is protruded from the outer peripheral surface of the connection post 25, and each tenon 251 is axially provided with a clamping groove 252. An L-shaped mortise 134 is formed on the inner circumferential surface of the through hole 131 corresponding to the position of each tenon 251, and an elastic tenon hook 135 (shown in fig. 2a) capable of being fastened to the corresponding groove 252 is disposed at the end of each mortise 134. Therefore, when the electric driving device 2 is installed in the installation space 13, the at least one tenon 251 of the connecting post 25 is inserted into the at least one mortise 134 aligned with the through hole 131, and then the electric driving device 2 is rotated to make the clamping groove 252 of each tenon 251 buckle with the elastic tenon hook 135 of each mortise 134, so as to prevent the electric driving device 2 from axially falling out of the installation space 13. At this time, the power input socket 21 is rotated to be aligned with the through hole 132.

In particular, the electric driving device 2 has the working voltage and current of 12 volts and 2 amperes respectively, the consumed power is 24 watts, and the electric driving device has the function of saving electricity.

In order to prevent the foreign objects from falling into the storage space 12, the top opening of the storage container 1 is sleeved with a top cover 19, the top cover 19 includes a fixed cover 191 located above the electric driving device 2, the fixed cover 191 is radially pivoted with a lifting cover 192 located above the storage space 12, and the lifting cover 192 can be lifted relative to the storage space 12 to supplement the objects to be ground, or the lifting cover can be closed to cover the top opening of the storage space 12. Wherein, the position of the fixed cover 191 corresponding to the power switch 22 is provided with a cover hole 193 for exposing the fixed cover to facilitate the operation. When the cover 192 is opened to a predetermined position, the inner edge thereof is just abutted against the power switch 22 to cut off the power, thereby stopping the operation of the electric driving device 2.

Referring to fig. 1, 3 and 5, the base 3 has a hollow stepped polishing chamber 31, and the periphery of the top surface of the polishing chamber 31 has at least two fastening grooves 311 for the hooks 123 to insert and fasten. The grinding chamber 31 is provided with a support member 312, the outer peripheral surface of the support member 312 is connected to the inner wall of the grinding chamber 31 by at least two fins 313, so that at least one discharge hole 314 is formed between the fins 313, the top surface of the support member 312 is provided with a pivot shaft 32, the pivot shaft 32 comprises a conical mandrel 321 axially mounted on the top surface of the support member 312, and a shaft sleeve 322 having a conical cavity for the mandrel 321 to be sleeved and mounted on the bottom surface of a driven rod 33. The mandrel 321 and the sleeve 322 are made of precise ceramics with acid and alkali resistance, good wear resistance and oxidation resistance, so as to obtain the advantages of low friction force, no oxidation and rust.

After the driven rod 33 is sleeved with a grinding disc 34 linked with the driven rod, the top and the bottom of the driven rod 33 are respectively sleeved on the output shaft 23 and the pivot 32, and the grinding disc 34 extends into the grinding base 14, so that a gap is formed between the two. Therefore, the driven rod 33 can rotate along with the output shaft 23 and synchronously drive the grinding disc 34 to grind in the grinding base 14.

Wherein the center of the grinding disc 34 is provided with a disc hole 341 for the driven rod 33 to pass through, and a retaining ring 331 is sleeved on the driven rod 33, so that the grinding disc 34 is prevented from falling off from the driven rod 33. Wherein the bottom surface of the grinding disc 34 and the adjacent surface of the bottom of the driven rod are provided with a non-circular groove 342 (shown in fig. 5) and a tenon 332 which are sleeved with each other, so that the driven rod 33 and the grinding disc 34 are in linkage relationship. The top edge of the disc hole 341 integrally extends downward to form a plurality of spiral wings 343, so that a plurality of spiral grooves 344 are formed between the wings 343, so as to facilitate the objects to be ground to be stirred by the wings 343, slide down along the spiral grooves 344, and then perform the grinding operation with the grinding teeth 145 of the grinding base 14 via a plurality of spiral bevel-toothed disc teeth 345 below the spiral grooves 344.

Because the inner diameter of the grinding base 14 is slightly smaller than the outer diameter of the bottom of the grinding disc 34, the grinding disc 34 does not completely enter the grinding base 14, and a gap is constantly maintained between the grinding disc and the grinding base. When the grinding disc 34 rotates, the grinding objects fall between the disc wings 343, and are driven by the disc wings 343 and the spiral grooves 344 to be ground between the disc teeth 345 and the grinding teeth 145, and then the powder with uneven thickness falls along the gap between the disc teeth 345 and the grinding teeth 145.

The powder with the particle size smaller than the gap passes through the discharge hole 314 and falls out of the grinding chamber 31; the powder having a particle diameter larger than the gap is continuously ground, so that powder having a uniform particle diameter can be obtained. Wherein, the grinding seat 14 and the grinding disc 34 are made of precise ceramics with acid and alkali resistance, good wear resistance and oxidation resistance, and will not be changed with the object to be ground.

A spacer 315 extends axially from the bottom of the base 3. the spacer 315 is coupled to, e.g., screwed to, an end of a bottom plate 35 at the bottom of the base 3, so that the base 3 can be stably placed. A receiving space 316 is formed between the bottom plate 35 and the discharge hole 314 so that a container 36 can be inserted into the receiving space, so that the ground powder falls from the discharge hole 314 and is directly received by the container 36.

In order to prevent the container 36 from falling out of the receiving space 316, a locking column 361 and an elastic protrusion 351 are oppositely arranged on the adjacent surfaces of the two, so that the container 36 can be firmly locked in the receiving space 316 when no force is applied.

Through the foregoing description, fig. 4 shows an assembled perspective view of the second embodiment of the grinder, and fig. 5 is a cross-sectional view of the second embodiment of the grinder.

Referring to fig. 5, in order to adjust the particle size of the ground powder, the grinding device first holds the base 3 with one hand and holds and rotates the rotating ring 172 between the object container 1 and the base 3 with the other hand, so that the lifting ring 16 connected to the bottom of the adjusting ring 17 axially moves along the adjusting ring 17 in the material inlet 122, and synchronously drives the grinding base 14, the fixing ring 15 and the material guiding ring 18 to axially move up and down, so as to change the size of the gap between the grinding base 14 and the grinding disc 34, thereby completing the adjusting step. The characteristic of this particle size thickness adjustment lies in that the existing grinder uses the grinding disc as the moving part, but the present disclosure uses the grinding base 14 as the moving part and connects to the lifting ring 16, so that the grinding base 14 moves up and down relative to the grinding disc 34 to change the gap size between them, so as to maintain the uniform particle size of the ground powder.

When cleaning, the user only needs to detach the top cover 19 from the top of the storage container 1 to reversely remove the electric driving device 2 from the device space 13, then detach the fixing ring 15 and the grinding base 14 from the lifting ring 16, separate the storage container 1 from the base 3, remove the driven rod 33 with the grinding disc 34, and finally detach the storage container 36 from the bottom of the base 3, thereby forming the most disassembled configuration shown in fig. 1. In this case, the user can wash most of the components except the electric driving device 2, especially the grinding base 14 and the grinding disc 34, with water to solve the problems of powder adhesion and odor emission.

Therefore, by implementing the present disclosure, the electric driving device is installed in the storage container by changing the spatial configuration of the grinder, so that the user can disassemble and clean the grinder without using tools with both hands, thereby avoiding the trouble of powder adhesion and odor emission, having the health and health requirements, overcoming the trouble of difficult disassembly and cleaning of the known electric grinder, and being an unprecedented good structure for similar articles.

The disclosure of the present disclosure is directed to preferred embodiments of the present disclosure, and any variations or modifications in detail, which are apparent to those skilled in the art from the technical spirit of the present disclosure, may be made without departing from the scope of the present disclosure.
