Description

Portable coffee machine

The present invention relates to a brewing device for coffee drinks, especially a portable coffee machine.

Since the nineteenth century, coffee has been promoted almost globally and has become one of the important trade commodities. The brewing and drinking forms of coffee beverages have their own characteristics in accordance with the different cultural habits of different regions. Among them, espresso (Espresso) is a special method of brewing coffee that is ground by high-pressure water flow through grinding into fine powder. It is generally thicker and contains higher concentration than coffee made by other methods. Suspended solids and dissolved solids (such as coffee fat), the flavor is more prominent, it is a strong taste of coffee drinks.

There are a certain number of supporters of espresso coffee, because the current culture of drinking coffee is quite popular. Even if you can’t use the equipment in your home to brew, or go directly to the coffee shop for consumption, a certain percentage of users want to be able to In the office, or during leisure activities such as hiking, camping, etc., you can still brew espresso for drinking. However, unlike the relatively simple hand brewing technique, brewing espresso requires a high-pressure water flow, which is more difficult to obtain than direct brewing with a dedicated machine. Moreover, compared with the use of special machines, the aftertreatment after brewing must also be considered, especially the water remaining in the coffee grounds after brewing will continue to trickle slowly, and it is also easy to produce if it is not handled carefully. Water droplets are splashing, and there may even be coffee stains.

Therefore, the purpose of the present invention is to provide a portable coffee machine that can brew espresso coffee and take care of the post-brewing treatment.

Therefore, the portable coffee machine of the present invention includes a body unit, a pneumatic unit detachably connected to the body unit, and a stand unit for the body unit to be erected.

The body unit includes a carrier, a container mounted on the carrier and defining a brewing space suitable for coffee powder, and a water inlet module disposed above the container and defining an inner space, And a jug detachably coupled to the carrier to position the container and the water inlet module.

The container has a bottom plate formed with a plurality of pores that communicate with the brewing space and can only pass water. The water inlet module is suitable for guiding water from the inner space to the brewing space. The water jug defines a water holding space communicating with the inner space through the water inlet hole, and has an air inlet communicating between the water holding space and the outside world.

The air pressure unit is connected to the air inlet of the jug of the body unit, and is used to provide high pressure gas to the water storage space at a predetermined pressure value.

The bracket unit includes a base frame, an extension body extending upward from the base frame, a support frame extending laterally from the extension body and for the body unit to be erected, and a water receiving tray located below the support frame.

Wherein, the adjusting member 142 is a needle valve, which can be adjusted in a rotating manner to change the pressure resistance of water flowing through the water inlet 140, thereby achieving the purpose of adjusting the water flow rate. In addition, the plate cover 141 has a plurality of scales 145 spaced apart from each other and disposed around the water inlet 140. The adjusting member 142 has a valve portion 146 screwed into the water inlet 140 and a valve portion 146 connected to the valve portion 146. A pointer 147 extending toward the scales 145 and corresponding to the scales 145 to indicate the water flow rate. By one of the scales 145 corresponding to the pointer 147 of the adjusting member 142, the corresponding water flow size can be visually known.

Referring back to FIGS. 1 and 2, the water jug 15 defines a water space 150 communicating with the inner space 130 through the water inlet 140, and has a pot body 151 defining the water space 150 and a The pot body 151 is suitable for displaying a barometer 152 of the air pressure value of the water holding space 150, an upper grip 153 connected to the pot body 151, an upper screw joint 154 formed on the pot body 151, and a It is formed in the pot body 151 and communicates with the air inlet 159 between the water holding space 150 and the outside. The type of the upper screw connection portion 154 corresponds to the lower screw connection portion 111 of the carrier 11, specifically, it can be a ring groove 158 for the clamping blocks 119 to be engaged. To assemble the body unit 1, as long as the container 11, the water inlet module 13, and the water tray 14 are sequentially stacked between the carrier 11 and the jug 15, then hold the upper When the grip 153 and the lower grip 112 are applied with an external force in the direction of rotation, the upper screw joint 15 and the lower screw joint 111 can be combined with each other to achieve the purpose of assembling the body unit 1.

The air pressure unit 2 is connected to the air inlet 159 of the jug 15 of the body unit 1 for providing high pressure gas to the water holding space 150 at a predetermined pressure value. In terms of the amount of brewing a single cup of espresso coffee, it is better to choose an air pump that can be held by hand and can provide 9 to 10 kg of air pressure, but as long as it can provide high-pressure gas with the required air pressure value, and Not limited to this.

The bracket unit 3 includes a base frame 31, an extension body 32 extending upward from the base frame 31, a support frame 33 extending laterally from the extension body 32 for the body unit 1, and a detachably mounted frame The extension body 32 is located on the water receiving tray 34 below the support frame 33. The extension body 32 has two longitudinally spaced clamping slots 321. The water receiving tray 34 is detachably fixed to the clamping slots 321 and can also be placed directly on the bottom frame 31.

Referring to FIG. 4 in conjunction with FIG. 1, when using this embodiment, the brewing space 120 of the container 12 is first filled with 25 to 35 grams of coffee powder, and then the water inlet module 13 and the water transfer tray 14 are sequentially placed After stacking, the upper grip 153 and the lower grip 112 can be held with both hands by the relationship between the jug 15 and the carrier 11 that can be assembled with each other to make the upper screw joint The assembly of the body unit 1 can be completed by rotating the 154 and the lower screw 111 in a relative rotation direction. Next, pre-fill 85-90°C water in the water holding space 150, and then connect the air pressure unit 2 to the air inlet 159 of the jug 15, operate the air pressure unit 2 and cooperate with the reading of the barometer 152, That is, high-pressure gas with an appropriate pressure value can be provided to the water holding space 150 through the air inlet 159. When the water in the water holding space 150 is subjected to a certain air pressure, in coordination with the adjustment of the adjusting member 142 of the water tray 14, the high-pressure gas and water flow can overcome the pressure resistance and flow into the inner space 130 through the water inlet 140, And when it trickles down to the bottom wall 131 of the water inlet module 13, it evenly drops onto the coffee powder contained in the brewing space 120 through the through holes 139, and it only takes about 20~ After 30 seconds, the brewed coffee will flow out from the fine holes 129 of the container 12.

It is worth noting that when using this embodiment to brew espresso coffee, the coffee powder contained in a single serving is only brewed by high-pressure water flow once, so the caffeine content is released compared to the slow brewing method. Out less. In addition, according to the flavor difference of each person's preference, the adjustment of the adjustment member 142 of the water adjustment tray 14 substantially affects the thickness of the water flow directly. When the pressure value is fixed, the brewing time is directly affected. For example, when brewing with a relatively small water flow, the time will be relatively longer, and the brewed coffee has a more burnt aroma; on the contrary, if the water flow is thicker, the brewing time is shorter, although the focus is not on the burnt aroma Taste, but you can also taste the diverse and delicate flavors belonging to various coffee beans.

Referring to FIGS. 4 and 5, in addition to the basic function of supporting the body unit 1, the support unit 3 can receive the residual liquid that may continue to drip from the brewing space 120 after completion of brewing . It should be particularly noted that the water receiving tray 34 is compared to being placed on the bottom frame 31, in order to avoid splashing caused by the residual liquid after the completion of brewing dripping from a relatively high position to the water receiving tray 34, the As shown in FIG. 5, the water tray 34 can be fixed on the clamping grooves 321 located relatively high, that is, relatively close to the container 12 to shorten the relative height of the droplets, which can effectively prevent the splashing of coffee residues.

In summary, in the portable coffee machine of the present invention, since the body unit 1 can be detached into a plurality of parts with a relatively small volume, and the air pressure unit 2 is easy to carry, it is easy to carry and easy to brew espresso coffee everywhere Demand. Through the design of the water receiving tray 34, the residual liquid dripping after brewing can be received and splashing can be avoided, thereby taking account of the post-brewing after treatment to maintain the cleanliness of the use environment, so it can really achieve the new cost purpose.
