Description

Imitation hand coffee machine

This creation is about a coffee machine, especially a hand-made coffee machine that can make a hand-made coffee and carry it with you.

The general hand coffee is a hand-held hand-washing pot, and the hot water in the hand-washing pot is injected into the filter cup which has been placed into the moderately ground coffee powder, wherein the hot water is injected into the filter bowl by the filter cup. The center moves outwards in a whirlpool manner, and then swirls around the center of the filter bowl to swirl the coffee, and waits until the amount of water reaches the required amount of water, so that the hot water can be fully steamed with the coffee powder. When steaming, when hot water comes into contact with the coffee powder, it will accelerate the carbon dioxide emission of the coffee powder, so that the sour taste of the coffee is discharged (the carbon dioxide has a sour taste. If there is no carbon dioxide emitted from the coffee when it is steamed, it will make the coffee have no Good sourness), and avoid carbon dioxide to block the contact between hot water and coffee to dissolve the aromatic substances and fats of the coffee, and then repeat the water injection in a whirlpool motion to brew the delicious hand-made coffee.

The coffee brewed is different from the coffee. The OTFES automatic hand coffee machine has the functions of screwing water and steaming. However, when the coffee machine is used, the coffee powder is set in the machine, so after the brewing, there is a problem of cleaning the coffee machine, and It is the same as the I536943 patent and the Oceanrich_CR8350BD and HARIO V60 coffee machines. They are too large to be placed in a fixed position and cannot be carried around. Therefore, for coffee lovers, there is no such thing. The function of brewing coffee at any time.

Electrical connection.

When using the copy-type coffee machine provided by this creation, the user must use the filter (not shown) is laid on a filter bowl 7, and then the ground coffee powder is poured on the filter screen, and then the copying coffee machine provided by the present invention is placed on the filter bowl 7, so that the clamping structure is The bottom of the jaw 41 of the 4 is placed above the edge of the cup of the filter bowl 7. Then, the copying machine provided by the present invention is activated, and the jaw 41 of the clamping structure 4 is pivoted to the position of the machine body 3 as an axis. The heart rotates, and the buckle portion 411 provided at the bottom of the jaw 41 is fastened to the outer edge of the filter cup 7 for fixing the copy coffee machine provided by the present invention above the filter bowl, and at the same time, the control circuit The fifth driving abutment member 320 is pivoted at a position pivotally connected to the lower base 312, and the free end of the abutting member 320 is pressed against the water injection pipe 329.

Then, the upper cover 2 is opened and hot water is poured from the opening 11 into the water cup 1, and the hot water is poured to the position of the required water amount scale 13 according to the coffee concentration to be brewed, and then, the operation portion 6 is selected to punch. In the present embodiment, the operation unit 6 provided by the artificial coffee machine provided by the present invention is a push switch. Therefore, the user can adjust the number of times the user operates the operation unit 6 to adjust the creation. The operation mode of the hand-operated coffee machine is continuous water injection mode or intermittent water injection mode.

Then, the copying coffee machine provided by the present invention controls the abutting member 320 to pivot about the position of the lower base 312 through the control circuit 5, so that the free end of the abutting member 320 stops pressing the water injection pipe 329. The hot water in the water cup 1 is caused to flow from the water outlet 12 through the water injection hole 331, the water outlet joint 332 and the water injection pipe 329 to the water outlet positioning joint 328, and the control circuit 5 activates the motor 321 to drive the helical gear 322 to rotate through the motor 321 and borrow The planetary bevel gear base 323 is driven by the gear teeth 3222 of the helical gear 322 to rotate in the positioning seat 31. At this time, the driven wheel 324 pivotally mounted on the base 3231 of the planetary gear carrier 323 revolves along with the planetary gear carrier 323, and Rotating by the gear shaft 3111 to rotate, and simultaneously driving the planetary gear 325 pivoted on one side of its axis to rotate around the internal gear 3261 of the internal gear base 326, at this time, the link 327 is pivoted to the planet One end of the gear 325 is subject to a planet The gear 325 is driven to follow the planetary gear 325, and when the planetary gear 325 moves around the inner gear 3261 to drive the connecting rod 327 to move away from the long hole 32311 away from the other end of the base 3231, the other end of the connecting rod 327 is pivoted. The connecting pipe 3281 is driven by the connecting rod 327 to move in the direction of the inner gear base 326 in the long hole 32311. At this time, the water discharging unit 3282 which is disposed under the base 3231 and pivoted with the connecting pipe 3281, along with the planetary gear The seat 323 rotates and gradually shifts to the axial center of the planetary gear holder 323, thereby forming a spiral path to the axis of the planetary gear holder 323. At this time, the hot water flowing into the water injection pipe 329 through the water cup 1 follows the water discharge unit. 3282 is injected into the filter bowl along the path of the spiral bypass.

Then, the control circuit 5 drives the abutting member 320 to pivot about the position of the lower base 312, and the free end of the abutting member 320 presses the water injection pipe 329 to stop the water injection, and the driving circuit also stops the motor 321 The operation causes the water discharge unit 3282 to stop the spiral bypass operation for steaming, discharging the sour taste of the coffee, and dissolving the aromatic substances and grease of the coffee, and then the control circuit 5 re-drives the motor 321 to start, and The free end of the abutting member 320 stops pressing the water injection pipe 329, and repeats the action of [0023] to restart the water injection to perform the brewing operation of the coffee.

In addition, when one end of the connecting rod 327 pivotally disposed on the planetary gear 325 is moved by the planetary gear 325 toward the elongated hole 32311 of the other end of the base 3231, the connecting pipe 3281 pivoted at the other end of the connecting rod 327 is received by the connecting rod 327. The movement moves away from the inner gear base 326 in the elongated hole 32311. At this time, the water outlet unit 3282 which is originally spirally spiraled toward the axis of the planetary gear holder 323 starts to form a spiral toward the outer edge of the planetary gear holder 323. The path of the bypass; therefore, when the planetary gear 325 circumscribes the inner gear 3261, the water outlet unit 3282 will walk a path that is spirally wound from the outer edge of the bottom of the planetary gear carrier 323 toward the axis and then outward. To achieve the purpose of spiral water injection Since the water outlet unit 3282 is pivotally connected to the connecting pipe 3281, when the water outlet unit 3282 is spirally wound, it is also rotated by the pivotal position with the connecting pipe 3281 to avoid the connection with the water discharging unit 3282. The water pipe 329 is knotted or torn off as the water discharge unit 3282 spirally bypasses.

In addition, the coffee brewing machine provided by the present invention can also control the water injection without using the abutting member 320 to press the water injection pipe 329, but at the water outlet 12, the water injection hole 331, the water injection joint 332, the water injection pipe 329 or An electric valve (not shown) is disposed on one of the water outlet units 3282, and the electric valve is controlled to be turned on or off through the control circuit 5 to control the water injection, thereby controlling the time of steaming.
