[0035] Embodiment 1

[0036] Refer to Figures 1-3 , the present utility model discloses a steam extraction device 1 for a powder brewing machine, which is used to be arranged below a powder supply device 3 provided with a powder dropping port 31. Specifically, the steam extraction device 1 includes a bracket 11 and an exhaust fan 12 installed at the bottom of the bracket 11. The bracket 11 is provided with a through hole communicating with the powder dropping port 31, and air inlet holes are provided on the side wall of the through hole of the bracket 11 and / or near the through hole; an air inlet duct communicating with the air inlet holes is formed inside the bracket 11; the exhaust fan 12 is communicated with the air inlet duct.

[0037] For the steam extraction device 1 of the present utility model, by providing the air inlet holes on the side wall of the through hole of the bracket 11 and / or near the through hole, when the exhaust fan 12 is started, the water vapor generated during the brewing process can be sucked away through the air inlet holes, thereby preventing the steam from entering the powder supply device 3 through the powder dropping port 31 and causing phenomena such as powder caking and mildew; in addition, by forming an independent air inlet duct inside the bracket, the inhaled water vapor can flow along the air inlet duct and finally be sucked away by the exhaust fan 12, thereby preventing the water vapor from entering the interior of the powder brewing machine and damaging the electronic devices, and thus ensuring the use safety and reliability of the product.

[0038] It should be noted that the powder brewing machine of the present utility model is particularly suitable for milk powder brewing machines, and is also applicable to coffee brewing machines, soybean milk brewing machines and other powder beverage brewing devices. Any beverage brewing device that generates water vapor during the brewing process belongs to the protection scope of this application.

[0039] Among them, a plurality of air inlet holes are provided and are distributed in a ring shape; with such an arrangement, the plurality of annularly arranged air inlet holes can achieve 360-degree dead-angle-free air extraction, thereby ensuring the uniformity of air extraction and improving the air extraction efficiency.

[0040] More specifically, refer to Figure 2 , the bracket 11 includes a base 111 and a cover plate 112 covering the top of the base 111. A first opening 1121 communicating with the powder dropping port 31 is formed on the cover plate 112; a second opening 1111 is formed on the base 111, and a second retaining wall 1112 surrounding the second opening 1111 is convexly provided on the base 111; the first opening 1121, the second retaining wall 1112 and the second opening 1111 are sequentially communicated to form the above-mentioned through hole; the intake hole is formed on the side wall of the second retaining wall 1112 and / or on the base 111 near the second opening 1111.

[0041] Specifically, the intake hole includes a plurality of first intake holes 1113 annularly and evenly distributed on the side wall of the second retaining wall 1112 and a plurality of second intake holes 1114 annularly and evenly distributed on the base 111 near the second opening 1111, and the plurality of second intake holes 1114 are arranged around the second retaining wall 1112.

[0042] Thus, when a large amount of water vapor is generated during the brewing process, most of the water vapor rises and is absorbed by the plurality of annularly distributed second intake holes 1114, and a small part of the water vapor enters the through hole and is absorbed by the plurality of first intake holes 1113, so as to effectively absorb all the water vapor to avoid entering the interior of the machine body 2 through the powder dropping port 31, thereby ensuring the reliability of air extraction.

[0043] Of course, it should be noted that in other embodiments, only a plurality of first intake holes 1113 or only a plurality of second intake holes 1114 may be arranged separately, and it can also meet the requirements of some brewing devices with a small amount of water vapor generated, and there is no limitation here.

[0044] Furthermore, a gas distribution ring 1115 is further provided on the base 111 between the intake air duct and the second retaining wall 1112, and a plurality of gas distribution holes 1116 are annularly distributed on the gas distribution ring 1115. Among them, the opening size of the gas distribution hole 1116 far from the exhaust fan 12 is larger than the opening size of the gas distribution hole 1116 close to the exhaust fan 12, so as to make the intake air volume of the plurality of intake holes evenly distributed, thereby ensuring the intake efficiency.

[0045] Thus, by arranging the gas distribution ring 1115 inside the bracket 11 and opening a plurality of gas distribution holes 1116 on the gas distribution ring 1115, and the opening size of the gas distribution hole 1116 far from the exhaust fan 12 is larger than the opening size of the gas distribution hole 1116 close to the exhaust fan 12, such a setting makes the intake of the plurality of intake holes uniform, thereby ensuring the air extraction effect and improving the air extraction efficiency.

[0046] In this embodiment, three air distribution holes 1116 are evenly spaced along the circumferential direction on the air distribution ring 1115. Two of the air distribution holes 1116 are arranged close to the exhaust fan 12 and are on the same straight line in the horizontal plane, while the other air distribution hole 1116 is arranged away from the exhaust fan 12 and is located behind the two air distribution holes 1116. The opening sizes of the two air distribution holes 1116 close to the exhaust fan 12 are smaller than the opening size of the one air distribution hole 1116 arranged away from the exhaust fan 12, so that the air intake amounts of the several first air intake holes 1113 and the several second air intake holes 1114 distributed in a ring are evenly distributed, thereby ensuring a better air extraction effect.

[0047] Of course, in other embodiments, other flow distribution mechanisms (such as arranging multiple air intake ducts, etc.) can also be used to achieve uniform distribution of the air intake amounts of multiple air intake holes, and there are no limitations here.

[0048] Furthermore, a first baffle 1117 is further provided on the base 111 to form an air intake duct around the outside of the air distribution ring 1115. The air distribution ring 1115 is located at one end of the air intake duct, and the exhaust fan 12 is connected to the other end of the air intake duct. Among them, an air extraction port 1118 communicating with the exhaust fan 12 is opened at the other end of the air intake duct on the base 111.

[0049] It should be noted that in other embodiments, structures such as the first baffle 1117, the second baffle 1112, and the air distribution ring 1115 provided on the base 111 can also be provided on the cover plate 112. When the cover plate 112 is covered on the base 111, it can also form structures such as through holes and air intake ducts, and there are no limitations here.

[0050] Embodiment Two

[0051] Refer to Figures 4-5 , the present utility model further provides a powder brewing machine, which includes a machine body 2, a powder supply device 3 arranged on the machine body 2, and a steam extraction device 1 as in Embodiment One arranged on the machine body 2 and located below the powder supply device 3.

[0052] When the steam extraction device 1 is arranged on the machine body 2 and located below the powder supply device 3, it can suck away the water vapor generated during the brewing process, preventing the steam from entering the powder supply device 3 through the powder dropping port 31 and causing phenomena such as powder caking and mildew.

[0053] Furthermore, the powder brewing machine further includes a mixer 4 arranged below the steam extraction device 1. Among them, a mixing cavity for fully mixing the powder and water is opened on the mixer 4, and the through hole on the bracket 11 is communicated with the mixing cavity.

[0054] Thus, when the powder brewer is in operation, hot water enters the mixer 4 through the water inlet interface and generates a large amount of steam. At this time, the steam extraction device 1 operates and extracts the steam from the mixing chamber, thereby avoiding the problem of the powder falling into the mixing chamber from caking due to water vapor, and further ensuring that the hot water and the powder can be fully mixed, thus greatly improving the brewing quality of the powder.

[0055] In summary, the steam extraction device 1 for a powder brewer and the powder brewer provided by the present utility model have the following technical effects:

[0056] (1) For the steam extraction device 1 of the present utility model, by arranging the air inlet holes on the side wall of the through hole of the bracket 11 and / or near the through hole, when the exhaust fan 12 is started, it can suck away the water vapor generated during the brewing process, preventing the steam from entering the powder supply device 3 through the powder dropping port 31 and avoiding phenomena such as powder caking and mildew. Additionally, by forming an independent air intake duct inside the bracket 11, the inhaled water vapor can flow along the air intake duct and finally be extracted by the exhaust fan 12, thus preventing the water vapor from entering the interior of the powder brewer and damaging the electronic components, and further ensuring the safe and reliable use of the product.

[0057] (2) For the steam extraction device 1 of the present utility model, by arranging the air inlet holes in a circular pattern, 360-degree air extraction without dead angles can be achieved, thereby ensuring the uniformity of air extraction and improving the air extraction efficiency.

With such a setting, the air intake of the multiple air inlet holes is uniform, thereby ensuring the air extraction effect and improving the air extraction efficiency.

[0059] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
