Description

Technical Field

[0001] The present disclosure relates to the technical field of coffee processing, and in particular to a coffee powder bin pressurizing mechanism and a coffee machine. Background Art

[0002] At present, with the development of social economy and the improvement of people's pursuit of quality life, drinking coffee has become a way of life for people. However, in order to be able to drink a cup of coffee anytime and anywhere, most manufacturers have produced a portable coffee machine. Using a portable coffee machine can make a cup of coffee easily.

[0003] For example, Chinese patent document CN209712559U discloses a portable coffee machine, which includes a hot water chamber, a pump pressure chamber, a brewing chamber and a drinking chamber. The hot water chamber heats the cold water and then enters the pump pressure chamber, which provides the coffee capsule in the extraction chamber with water required for brewing coffee. The coffee capsule is fixed in the extraction chamber by a fixed shell, and the extraction chamber cover covers the extraction chamber.

[0004] However, the above-mentioned portable coffee machine has the following problems:

[0005] Although the portable coffee machine can increase the water required for brewing coffee for the coffee capsule through the pumping chamber, so that the coffee is extracted in the extraction chamber, since the water in the extraction chamber is extracted once by the pumping chamber, different coffee powders are ground to different degrees, and the coffee powders are extracted with hot water only once, causing some coffee powders to flow into the coffee cup without being completely extracted, so that thick and oily coffee cannot be extracted, which greatly affects the taste of the coffee. Utility Model Content

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a coffee powder bin pressurizing mechanism and a coffee machine for secondary pressurized filtered coffee powder.

[0007] The purpose of this disclosure is achieved through the following technical solutions:

[0008] A coffee powder bin pressurizing mechanism comprises a powder bowl support, a pressurizing component and a powder storage bin; the powder storage bin is arranged in the powder bowl support, and a filter hole is opened at the bottom of the powder storage bin;

[0009] The boost component is arranged in the powder bowl bracket, and the boost component includes a boost bracket, a filter and a water outlet. The boost bracket is provided with a diversion collection port and a contraction port which are connected in sequence; the boost bracket is arranged below the powder storage bin, and the diversion collection port is arranged opposite to the filter hole; the water outlet is arranged on the boost bracket and covers the contraction port; the filter is arranged between the contraction port and the water outlet, and the contraction port is connected to the outlet of the water outlet through the filter.

[0010] In one of the embodiments, the booster bracket further includes a liquid deflector, the liquid deflector abuts against the bottom of the powder storage bin, the liquid deflector is provided with a diversion ramp, and the two ends of the diversion ramp are respectively connected to the filter hole and the contraction port.

[0011] In one embodiment, the diversion ramp extends upward in a trumpet shape.

[0012] In one of the embodiments, a primary filter is embedded in the bottom of the powder storage bin, the filter hole is opened on the primary filter, a liquid containing cavity is opened between the primary filter and the bottom of the powder storage bin, and a single filter hole is opened in the center of the bottom of the powder storage bin, and the filter hole is communicated with the liquid containing cavity.

[0013] In one embodiment, the filter element is composed of a plurality of stacked filter sheets.

[0014] In one of the embodiments, a sealing ring is further provided between the water outlet and the booster bracket, and the sealing ring surrounds the contraction opening.

[0015] In one of the embodiments, a silicone ring kit is provided on the outer peripheral wall of the powder bowl support, and the silicone ring kit is sleeved on the powder bowl support.

[0016] In one embodiment, the water outlet nozzle is composed of a single or multiple water outlet holes, and the water outlet nozzle is arranged below the filter element.

[0017] In one of the embodiments, the liquid deflector is disposed in the diversion collection port, and an embedded port is protruded toward the contraction port; the embedded port is connected to the diversion ramp, and a circle of fixed bosses is protruded toward the peripheral wall of the contraction port toward the embedded port.

[0018] A coffee machine comprises the coffee machine and the coffee powder bin pressurizing mechanism described in any one of the above embodiments.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] 1) By opening a filter hole in the powder storage bin, when the coffee powder cake is put into the powder storage bin and hot water passes through the powder storage bin, the coffee powder will be filtered for the first time in the powder storage bin. Because the booster bracket is arranged below the powder storage bin and the diversion collection port is opposite to the filter hole, after the coffee extract is filtered through the filter hole, it will flow to the diversion collection port. The booster bracket is provided with a contraction port connected to the diversion collection port. When the coffee extract enters the contraction port, the contraction of the contraction port increases the downward pressure of the coffee extract, so that the coffee extract merges with the air. At the same time, the filter is arranged between the contraction port and the water outlet. The coffee extract will be extracted for the second time after passing through the filter and then flows into the coffee cup through the water outlet, thereby forming a thick and oily coffee.

[0021] 2) A portable coffee machine according to the prior art, wherein the coffee powder bin pressurizing device filters the coffee extract for the first time through the filter holes of the powder storage bin and then flows into the powder bowl holder, and a diversion collection port and a contraction port are connected in the pressurizing holder. When the coffee extract enters the diversion collection port, it passes through the compression port. The coffee extract flowing into the compression port merges with the air, making the coffee extract thicker and richer in fat. The filter element is connected to the contraction port, so that the coffee extract is filtered and pressurized for a second time in the filter element, and finally flows into the coffee cup through the mouth of the water outlet, thereby avoiding the problem that the coffee powder of different grinding degrees is only extracted once and thus the best effect of coffee powder extraction cannot be achieved, so that a cup of thick and fat-rich coffee flows out of the water outlet, thereby reducing the requirement on the coarseness of the coffee powder grinding.

DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present disclosure are given in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0032] like Figure 1 to Figure 2As shown, a coffee powder bin pressurizing mechanism 20 of an embodiment includes a powder bowl support 100 and a powder storage bin 200; the pressurizing component includes a pressurizing support 300, a filter 380 and a water outlet 390, the powder storage bin 200 is arranged in the powder bowl support 100, and a filter hole 220 is opened at the bottom of the powder storage bin 200; the powder bin pressurizing mechanism also includes a pressurizing component; the pressurizing component is arranged in the powder bowl support 100, and the pressurizing support 300 is sequentially opened with a diversion collection port 310 and a contraction port 320 that are connected; the pressurizing support 300 is arranged below the powder storage bin 200, and the diversion collection port 310 is arranged opposite to the filter hole 220; the water outlet 390 is arranged on the pressurizing support 300 and covers the contraction port 320; the filter 380 is arranged between the contraction port 320 and the water outlet 390, and the contraction port 320 is connected to the outlet of the water outlet 390 through the filter 380.

[0033] It can be understood that by providing the filter hole 220 in the powder storage bin 200, when the coffee powder cake is placed in the powder storage bin 200 and the hot water passes through the powder storage bin 200, the coffee powder will be filtered for the first time in the powder storage bin 200. Because the booster bracket 300 is arranged below the powder storage bin 200 and the diversion collection port 310 is opposite to the filter hole 220, when the coffee extract is filtered through the filter hole 220, it will flow into the diversion collection port 310, and the booster bracket 300 is provided with a contraction port 320 connected to the diversion collection port 310. When the coffee extract enters the contraction port 320, the contraction of the contraction port 320 will increase the downward pressure of the coffee extract, so that the coffee extract merges with the air. At the same time, the filter element 380 is arranged between the contraction port 320 and the water outlet 390. The coffee extract will be extracted for the second time after passing through the filter element 380, and then flow into the coffee cup through the water outlet 390, thereby forming a thick and oily coffee.

[0034] It can be understood that, compared with a portable coffee machine 10 in the prior art, the coffee powder bin pressurizing device mentioned above filters the coffee extract for the first time through the filter hole 220 of the powder storage bin 200 and flows into the powder bowl holder 100. At the same time, a diversion collection port 310 and a contraction port 320 that are connected are provided in the pressurizing holder 300. When the coffee extract enters the diversion collection port 310, it will pass through the compression port. The coffee extract that flows into the compression port will merge with the air, making the coffee extract thicker and rich in fat. The filter element 380 is connected to the contraction port 320, so that the coffee extract will be filtered and pressurized for the second time in the filter element 380, and finally flow into the coffee cup through the mouth of the water outlet 390, avoiding the problem that the coffee powder of different grinding degrees is only extracted once and thus the best effect of coffee powder extraction cannot be achieved. The water outlet 390 flows out a cup of thick and fat-rich coffee, thereby reducing the requirements for the coarseness of the coffee powder grinding.

[0035] Combination Figure 1 and Figure 2 As shown, specifically, the booster bracket 300 further includes a liquid deflector 370, the liquid deflector 370 abuts against the bottom of the powder storage bin 200, and the liquid deflector 370 is provided with a diversion ramp 3710, which extends inwardly to the contraction port 320. It can be understood that the liquid deflector 370 is sleeved on the bottom of the powder storage bin 200, and when the coffee extract passes through the powder storage bin 200 for the first filtration extraction, the coffee extract will flow into the liquid deflector 370, and at the same time, the liquid deflector 370 is provided with a diversion ramp 3710, and the extract will flow along the diversion ramp 3710 to the contraction port 320, so that the coffee extract flows more smoothly to the filter element 380, which is conducive to controlling the flow direction and speed of the coffee liquid and ensuring the final coffee extraction quality.

[0036] Combination Figure 1 and Figure 2 As shown, specifically, the guide ramp 3710 extends upward in a trumpet shape. It can be understood that the guide ramp 3710 is set to open upward in a trumpet shape, so that the guide ramps 3710 on both sides extend inward to the contraction port 320, so that the coffee liquid flows evenly to the contraction port 320 for pressure-boosting filtration. At the same time, the trumpet shape can effectively reduce the overflow of the pressurizing bracket 300 due to excessively fast or uneven flow rate, so that the liquid can be smoothly introduced into the contraction port 320 and the filter element 380.

[0037] Combination Figure 1 and Figure 2 As shown, in one embodiment, a primary filter 210 is embedded in the bottom of the powder storage bin 200, a filter hole 220 is opened on the primary filter 210, a liquid containing cavity 230 is opened between the primary filter 210 and the bottom of the powder storage bin 200, and a single filter hole 220 is opened at the center of the bottom of the powder storage bin 200, and the filter hole 220 is communicated with the liquid containing cavity 230. It can be understood that a primary filter 210 is embedded at the bottom of the powder storage bin 200. When coffee powder is placed in the powder storage bin 200 and hot water is added, the coffee powder will be extracted through the primary filter 210 into coffee liquid and flow into the liquid containing chamber 230. A single filter hole 220 is provided at the bottom of the powder storage bin 200. When the coffee liquid flows into the liquid containing chamber 230, the coffee liquid will enter the filter hole 220 and enter the diversion collection port 310. Because a single filter hole 220 is provided at the bottom of the powder storage bin 200, when the coffee liquid enters the diversion collection port 310, the coffee liquid will be squeezed toward the filter hole 220 and flow into the diversion collection port 310, thereby increasing the pressure of the coffee liquid and ensuring the pressure required for the coffee liquid to undergo secondary filtration by the filter element 380, which is beneficial to the fusion of the coffee liquid and the air.

[0038] like Figure 1As shown, in one embodiment, the filter element 380 is composed of a plurality of stacked filter sheets. It can be understood that the filter element 380 is configured to be composed of a plurality of stacked filter sheets, so that each layer of filter sheets can filter coffee particles and impurities of different sizes, thereby achieving a finer filtering effect, and the multi-layer stacked filter sheets can enhance the structural stability and durability of the filter element 380, reducing maintenance costs and the need for frequent replacement.

[0039] like Figure 1 As shown, a sealing ring 340 is further provided between the water outlet 390 and the boost bracket 300, and the sealing ring 340 surrounds the contraction opening 320. It can be understood that by providing the sealing ring 340 between the water outlet 390 and the boost bracket 300, and the sealing ring 340 surrounds the contraction opening 320, the liquid of the boost bracket 300 is prevented from flowing out from the inside to the outside during operation, and the structural stability of the boost bracket 300 is increased.

[0040] like Figure 4 As shown, a silicone ring set 110 is provided on the outer peripheral wall of the powder bowl support 100, and the silicone ring set 110 is sleeved on the powder bowl support 100. It can be understood that the silicone ring set 110 is provided on the outer peripheral wall of the powder bowl support 100, and the silicone ring set 110 is sleeved on the powder bowl support 100, so that when the user twists the coffee machine 10, the user grabs the silicone ring set 110 to separate the coffee powder bin pressurizing mechanism 20 from the coffee machine 10, which prevents the hand from slipping too much due to twisting the coffee machine 10, thereby preventing the coffee powder bin pressurizing mechanism 20 from falling off the ground.

[0041] Combination Figure 1 and Figure 3 As shown, the water outlet 390 is composed of a single or multiple water outlet holes, and the water outlet 390 is arranged below the filter 380. It can be understood that the water outlet 390 is arranged as multiple or single water outlet holes, and is arranged below the filter 380 at the same time, so that after the coffee liquid is filtered through the filter 380, it can flow out from the multiple water outlet holes to the coffee cup, so that the coffee liquid can flow into the coffee cup quickly, avoiding the situation where the contraction port 320 is blocked due to the slow flow rate of the water outlet 390.

[0042] Combination Figure 1 and Figure 2As shown, the liquid flow guide 370 is arranged in the flow guide collection port 310, and an embedded port 3720 is protruded toward the contraction port 320; the embedded port 3720 is connected to the flow guide ramp 3710, and the contraction port 320 is protruded with a circle of fixed bosses 3730 toward the peripheral wall of the embedded port 3720. It can be understood that by protruding an embedded port 3720 at the contraction port 320, and the embedded port 3720 is connected to the flow guide ramp 3710, and the fixed bosses 3730 are protruded on the peripheral wall of the embedded port 3720, the contraction port 320 and the flow guide collection port 310 can always be kept on the same vertical line, ensuring that the extraction liquid can smoothly flow into the filter element 380.

[0043] A coffee machine 10 includes a coffee powder bin pressurizing mechanism 20 according to any one of the above embodiments. It can be understood that by applying the coffee powder bin pressurizing mechanism 20 disclosed in the present invention to the coffee machine 10, the situation that the coffee powders of different grinding degrees are only extracted once and thus the best effect of coffee powder extraction cannot be achieved is avoided, so that the coffee machine 10 can extract a cup of thick and oily coffee, and the requirement on the grinding coarseness of the coffee powder is reduced.

[0044] Compared with the prior art, the present invention has at least the following advantages:

[0045] 1) By providing a filter hole 220 in the powder storage bin 200, when the coffee powder cake is placed in the powder storage bin 200 and hot water passes through the powder storage bin 200, the coffee powder will be filtered for the first time in the powder storage bin 200. Because the booster bracket 300 is arranged below the powder storage bin 200 and the diversion collection port 310 is opposite to the filter hole 220, after the coffee extract is filtered through the filter hole 220, it will flow into the diversion collection port 310. The booster bracket 300 is provided with a contraction port 320 connected to the diversion collection port 310. When the coffee extract enters the contraction port 320, the contraction of the contraction port 320 increases the downward pressure of the coffee extract, so that the coffee extract merges with the air. At the same time, the filter 380 is arranged between the contraction port 320 and the water outlet 390. The coffee extract will be extracted for the second time after passing through the filter 380 and then flow into the coffee cup through the water outlet 390, thereby forming a thick and oily coffee.

[0046] 2) A portable coffee machine 10 according to the prior art, wherein the coffee powder bin pressurizing device performs the first filtration through the filter holes 220 of the powder storage bin 200, and the coffee extract flows into the powder bowl holder 100. At the same time, a diversion collection port 310 and a contraction port 320 are provided in the pressurizing holder 300. When the coffee extract enters the diversion collection port 310, it passes through the compression port. The coffee extract flowing into the compression port will merge with the air, making the coffee extract thicker and richer in fat. The filter element 380 is connected to the contraction port 320, so that the coffee extract will be filtered and pressurized for a second time at the filter element 380, and finally flow into the coffee cup through the mouth of the water outlet 390, thereby avoiding the problem that the coffee powder of different grinding degrees is only extracted once and thus the best effect of coffee powder extraction cannot be achieved. The water outlet 390 flows out a cup of thick and fat-rich coffee, thereby reducing the requirement on the coarseness of the coffee powder grinding.

[0047] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
