[0032] Example

[0033] See also Figures 1 to 4 The utility model provides a hand brewing device that can be suspended and supported, which can be used to brew various beverage materials such as coffee, tea, roselle tea, fruit tea or health tea. The following description takes coffee as a representative beverage material.

[0034] The hand-washing device that can be suspended and supported comprises a filter paper holder 1 and a filter paper 3, and may further comprise a filter paper seat 2. Figure 1 Taking the commonly seen V-shaped (or cone-shaped, hereinafter referred to as V-shaped) hand brewing cup as the first embodiment, the filter paper 3 can be a commercially available product, including V1 filter paper for brewing 1 to 2 cups at a time and V2 filter paper for brewing 2 to 4 cups at a time. Figure 1 In this example, V1 filter paper is selected, but not limited thereto. The utility model replaces the V-shaped hand-injected cup with a filter paper holder 1 , the filter paper holder 1 is a hollow body, and the inner diameter of the lower end of the filter paper holder 1 can be greater than the outer diameter of the lower end of the filter paper holder 2 .

[0035] The filter paper holder 1 has a support mechanism at its upper end. In this embodiment, the filter paper holder 1 has an upper inclined surface 11 at its inner upper end. The upper inclined surface 11 is inclined and surrounds a circle. The upper inclined surface 11 just touches the filter paper 3 and can be used to support the filter paper 3 to be suspended on the filter paper holder 1. The filter paper holder 1 has a filter paper slot 12 at its inner upper end. The filter paper slot 12 can be arranged at the upper end of the upper inclined surface 11. The filter paper slot 12 can be arranged horizontally and surround a circle. The upper inclined surface 11 and the filter paper slot 12 can form a support mechanism and can be used to support the filter paper 3 in the air.

[0036] The filter paper 3 has a brewing area 31 inside, and the brewing area 31 can be used to place beverage materials such as coffee for brewing the beverage materials. The brewing area 31 is located below the support mechanism, and the brewing area 31 is located below the upper end of the filter paper 3. The brewing area 31 and the upper end of the filter paper 3 are spaced apart, so that when the filter paper 3 is placed on the filter paper holder 1, the brewing area 31 of the filter paper 3 can be spaced apart from the support mechanism of the filter paper holder 1, and the brewing area 31 is lower than the support mechanism of the filter paper holder 1.

[0037] The filter paper holder 2 has a conical surface 21 at its inner center, which can correspond to a conical outer surface 32 of the filter paper 3 and can be used to position the filter paper 3, so that the filter paper 3 and the filter paper holder 2 can be tangentially fitted, and the filter paper 3 can be more stably arranged. The filter paper holder 2 can have an outer inclined surface 22 on its outer side, so that the filter paper holder 1 can be easily assembled and removed from top to bottom.

[0038] A water guide 4 may be provided above the filter paper holder 1. The water guide 4 may be provided with a plurality of hot water outlet holes 41, so that the hot water can be evenly distributed and flow down to brew coffee. The water guide 4 may have a lower ring 42. When assembled to the filter paper holder 1, the lower ring 42 can be used to press the filter paper 3 so that the filter paper 3 is stuck in the filter paper slot 12.

[0039] Pre-operation procedure: The filter paper holder 2 can be placed on the operating table, the filter paper holder 1 is put on the filter paper holder 2 from top to bottom, and then the filter paper 3 is assembled so that the filter paper 3 fits the conical surface 21 of the filter paper holder 2 and the upper inclined surface 11 of the filter paper holder 1, and a proper amount of ground coffee powder is added. The lower ring 42 of the water guide 4 is pressed down on the filter paper slot 12 of the filter paper holder 1, so that the filter paper 3 is as shown in FIG. Figure 2 As shown, it is stuck on the filter paper holder 1, and then Figure 3 As shown, the filter paper holder 1 is lifted up to perform the subsequent hand-brew coffee brewing procedure, and the filter paper holder 2 is detached and remains in the original position.

[0040] When brewing hand-brewed coffee (beverage material), hot water flows down from the hot water outlet hole 41 of the water guide 4 into the coffee powder. During the brewing process, the coffee powder will expand and the water level will rise. Regardless of manual brewing or automatic brewing, the amount of hot water is controlled appropriately so that the highest point of the brewing water level is below the reserved space, so that the coffee liquid will not touch the filter paper holder 1 and the water guide 4. After the hand-brewed coffee brewing process is completed, the filter paper holder 1 is moved as a whole to the top of the coffee grounds container, the water guide 4 is taken out, and the filter paper holder 1 is gently shaken. The coffee grounds containing water in the filter paper 3 and the filter paper 3 fall into the coffee grounds container, completing the last process of hand-brewed coffee. The filter paper holder 1 and the water guide 4 are kept clean because they are not stained with coffee liquid at all, and the next brewing process can be carried out without cleaning.

[0041] Filter paper holder 1 embodiment 2: The difference from embodiment 1 is that the filter paper holder 1 of this embodiment has no filter paper slot. The filter paper holder 1 of this embodiment has the same upper inclined surface 11, which can be tangent to the conical surface of the filter paper 3, such as Figure 5 and Figure 6 As shown, after the filter paper 3 is installed, a proper amount of coffee powder that has been ground into a proper coarseness is put in, and the upper end of the filter paper 3 protrudes from the upper end of the filter paper holder 1, and the filter paper 3 on the filter paper holder 1 (such as Figure 6 As shown in the figure, press the upper end of the filter paper 3 with your hand, fold the protruding filter paper 3 downward, bend it 360 degrees and then flatten it. You can fold the filter paper 3 flat first and then put the coffee powder. To facilitate the folding of the filter paper 3 that exceeds the upper end, a larger filter paper can be used for the filter paper 3, such as V2 filter paper for brewing a single cup of hand-brewed coffee. After the filter paper 3 that exceeds the upper end of the filter paper holder 1 is folded down and flattened, the bent filter paper 3 is hung and clamped on the upper end of the filter paper holder 1 (as shown in the figure). Figure 7 As shown in the figure, after the coffee powder is actually loaded and hot water is used to brew coffee, the tension of the folded filter paper 3 will make the filter paper 3 stuck on the upper end of the filter paper holder 1 and will not slide.

[0042] like Figure 7 and Figure 8 As shown, the inner diameter of the lower ring 42 of the water guide 4 is larger than the outer diameter of the upper end of the filter paper holder 1 on which the filter paper 3 is mounted, so that the water guide 4 is easily mounted on the filter paper holder 1 and has a pressing function, so that the filter paper 3 in brewing is more firmly secured and does not fall off. The lower ring 42 of the water guide 4 can be slightly larger and rounded, so that the water guide 4 is easier to assemble on the filter paper holder 1.

[0043] like Fig. 9 and Fig.10 As shown, the third embodiment of the filter paper holder 1 is different from the first and second embodiments in that the present embodiment has no filter paper slot and upper inclined surface. In the present embodiment, an upper ring body 14 may be provided at the upper end of the filter paper holder 1. The upper ring body 14 is surrounded in a circle. The upper ring body 14 may form a supporting mechanism. The upper ring body 14 can contact the outer side of the filter paper 3 to support the filter paper 3 in mid-air. The operating steps are the same as those of the second embodiment and will not be repeated.

[0044] like Fig.11 As shown, the fourth embodiment of the filter paper holder 1: brewing filter paper for hand-brewed coffee, in addition to the V-shaped filter paper, another commonly used type on the market is T-shaped filter paper. The filter paper holder 1 of this embodiment has the same filter paper slot 12 as that of the first embodiment. The filter paper 3 uses T-shaped filter paper. The inner size of the filter paper holder 2 corresponds to the outer size of the T-shaped filter paper, so that the T-shaped filter paper can fit tightly on the T-shaped filter paper holder 2. The operation execution procedure is the same as the previous embodiment and will not be repeated.

[0045] The four filter paper holder embodiments described above all use the filter paper holder 2 to assemble and position the filter paper 3. After skilled operation, the filter paper 3 can be assembled and positioned on the filter paper holder 1 without the filter paper holder 2 according to experience. Therefore, the filter paper holder 2 can be used or not, and can be omitted according to the situation. The main design feature of the filter paper holder 1 is that the brewing area 31 of the filter paper 3 is suspended in the air, and the brewing area 31 is lower than the supporting mechanism of the filter paper holder 1, so that the filter paper holder 1 will not contact the coffee liquid and can be kept clean. It can be used again without cleaning after use, which can ensure no food hygiene problems.

[0046] Brewing Example 1: Fig.12 As shown, this embodiment provides a brewing mechanism for brewing coffee in places where there is a lack of water and electricity, especially outdoor coffee carts.

[0064] Execution procedure: In this embodiment, a suitable coffee bag is prepared in advance. A barcode is printed on the packaging bag of the coffee bag. The barcode content is the brewing procedure of the coffee powder. The automatic control system stores the coffee brewing procedure of each barcode. When the water storage tank 20 is on standby, there is no water stored. When brewing coffee, the barcode on the coffee bag is first scanned on the barcode scanner 8. After scanning, the electronic scale 6 counts seconds and the measurement is reset to zero. The automatic control system calculates the appropriate ratio according to the required brewing water volume, brewing temperature, hot water temperature of the hot water insulation barrel 5a and cold water temperature of the cold water insulation barrel 5b according to the barcode content, first opens the cold water solenoid valve 52b of the cold water insulation barrel 5b to output cold water, and closes the cold water solenoid valve 52b when the electronic scale 6 detects an appropriate amount of cold water, and then opens the hot water solenoid valve 52a of the hot water insulation barrel 5a. When the electronic scale 6 detects an appropriate amount of hot water, the hot water solenoid valve 52a is closed, and the water tank 20 is mixed with the desired amount of hot water and temperature for standby use. The coffee bag is torn open and the coffee powder is poured into the filter paper 3 of the brewing device. After the water guide 4 is properly placed, the brewing device is positioned and the operation key is pressed. The automatic control system opens and closes the brewing solenoid valve 30 according to the number of coffee brewing stages, the water output of each stage and the brewing time in the established program. The electronic scale 6 calculates the water storage tank 20 water storage reduction and the number of seconds. When the electronic scale 6 detects that the water storage tank 20 is zero in the last stage of hot water brewing, the brewing solenoid valve 30 is closed. When the total brewing time is reached, a sound or light signal can be emitted to indicate that the coffee brewing program is completed. If the wash-free brewing mechanism of the utility model is used indoors, the barcode can also be directly generated by the ordering machine (POS machine).

[0065] In addition, the hand-infusing device of the utility model can be suspended and directly placed under the brewing device, and the brewing device (not shown) outputs hot water to brew beverage materials, and the flow meter of the brewing device can be used for metering. The utility model can also be used to brew health tea (such as Chinese medicine). During the process of brewing beverage materials, the hand-infusing device will not touch the soup, and the occurrence of tampering can also be avoided.
