[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments and descriptions are used to explain and understand the present invention, but are not intended to limit the present invention.

[0025] Reference Figures 1-5 As shown, this utility model discloses a coffee brewing device, including a funnel support assembly 10 and a coffee funnel assembly 20. The funnel support assembly 10 includes a brewing head 101, a one-way valve body 107 installed on the upper part of the brewing head 101, a water inlet pipe 106 and a pressure relief pipe 111 connected to the one-way valve body 107, a water outlet hole 101A in the middle of the brewing head 101, four water outlet holes 101A are arranged in a ring around the middle of the brewing head 101, a filter plate 113 is arranged below the water outlet hole 101A, and the filter plate 113 is fixedly installed on the lower part of the brewing head 101. The coffee funnel assembly 20 is installed on the funnel support assembly 10, and a brewing chamber 30 is formed between the brewing head 101 and the coffee funnel assembly 20. Diverting grooves are arranged at intervals from the middle of the brewing head 101 outward. The diversion channels are arranged at intervals from the center of the brewing head 101 outwards, namely the first diversion channel 101C. In order to make the hot water of the filter 113 evenly brew the coffee powder in the coffee funnel assembly 20, the diversion channels are arranged at intervals from the center of the brewing head 101 outwards, namely the second diversion channel 101E.

[0026] Reference Figure 2 and Figure 6As shown, a sealing ring 112 is provided between the coffee funnel assembly 20 and the funnel support assembly 10. The coffee funnel assembly 20 includes a funnel 201 and a filter cup 202 disposed in the funnel 201. The funnel support assembly 10 includes a funnel support 101 and a brewing head 101 disposed within the funnel support 101. A sealing ring 112 is provided between the brewing head 101 and the funnel 201. The top of the sealing ring 112 is provided with an upper groove 1121, and the inner circumference of the sealing ring 112 is provided with an inner groove 1122. The function of providing a sealing ring 112 between the brewing head 101 and the funnel 201 is to form a sealed brewing chamber 30 between the brewing head 101 and the filter cup 202 containing coffee powder in the funnel 201. The inner circumference of the sealing ring 112 is provided with an inner groove 1122, which is used to improve the sealing effect between the brewing head 101 and the funnel 201 containing coffee powder. The funnel 201 is equipped with a filter cup 202, and the coffee powder is pressed into the filter cup 202.

[0027] Reference Figure 4 and Figure 5 As shown, a second water outlet 101B is also provided next to the water outlet 101A. The second water outlet 101B can release the pressure in the brewing chamber 30 in a timely manner through the pressure relief pipe 111 to ensure safety during use. If the pressure in the brewing chamber is high after brewing coffee, it will be difficult to unscrew the high-pressure funnel, or the unscrewed coffee may easily burst. This structure is to reduce safety hazards. The surface of the brewing head 101 is provided with multiple protrusions 101D at intervals. The protrusions 101D are located between the brewing head 101 and the filter plate 113. This ensures that the filter plate is not easily deformed under pressure, so that the area of ​​the diversion channel is not affected, thus improving the stability of the product. The filter plate 113 is fixedly installed at the bottom of the brewing head 101 by countersunk screws 114.

[0028] Reference Figure 1 and Figure 4 As shown, the funnel support 100 of the funnel support assembly 10 has a retaining rib 10A on its inner circumference for limiting the coffee funnel assembly 20. Multiple evenly distributed retaining ribs 10A are designed on the funnel support assembly 10 to ensure that the funnel 201 is not eccentric during rotational assembly, thus avoiding affecting the snap-fit ​​area between the high-pressure funnel 201 and the funnel support 100.

[0029] Reference Figure 2 and Figure 3As shown, the end of the one-way valve body 107 is provided with at least two grooves 107A spaced apart. This invention uses two grooves 107A, and an O-ring seal 105 is fitted inside each groove 107A. The one-way valve body 107 is interference-fitted and fixedly installed on the top of the brewing head 101. The interference fit with the funnel support 100 improves the sealing performance between the one-way valve body 107 and the funnel support 100. The one-way valve body 107 includes a one-way valve 109 and a water outlet spring 110. The one-way valve body 107 is fixedly installed on the funnel support 100 by a fixing plate 102 and a pressure plate 103. One end of the top of the one-way valve body 107 is connected to a water inlet pipe 106, and the other end is connected to a second water pipe 108, which can be connected to a pressure gauge for testing pressure.

[0030] Because the present invention has a distribution groove set at intervals from the middle to the outer periphery of the brewing head, hot water can be evenly distributed on the filter plate 113 through the distribution groove. The hot water is then evenly injected into the funnel 201 through the filter plate 113. The hot water can fully soak the coffee powder in every corner of the funnel 201, and the fully brewed coffee has the advantages of rich oil and good taste.

[0031] The above description is only for the convenience of illustrating this utility model. Various simple modifications and alterations made by those skilled in the art without departing from the spirit and scope of this utility model should still fall within the protection scope of this utility model.
