With reference to fig. 1 to 18, a hot beverage machine comprises a main machine 1 and a brewing assembly 2.

Referring to fig. 1, 2, 12 and 13, the main body 1 includes a frame 11 and a water supply mechanism 12 fixed on the frame 11, the water supply mechanism 12 is provided with a water supply port 121 capable of intermittently supplying hot water with minute pressure, and the frame 11 is provided with a liftable supporting part 111 below the water supply port 121. The hot water with minute pressure supplied here means that a part of gas is supplied together with the water supply, so that the internal gas pressure can be increased in the closed vessel.

With reference to fig. 2 to 11, the infusion assembly 2 comprises a first capsule 21, a filter assembly 22 and a second capsule 23; the first container 21 is provided with a water inlet 211 and a water outlet 212 positioned at the lower end of the first container 21; the water inlet 211 is connected with the frame 11 through a first positioning connecting structure 3 and is in sealed communication with the water supply inlet 121; the filter assembly 22 is fixed at the water outlet 212; a first opening 231 is arranged at the upper end of the second container 23; the supporting part 111 is provided with a second positioning structure 4, and the second container 23 can be placed on the supporting part 111 and positioned by the second positioning structure 4, so that the first opening 231 is located below the water outlet 212; the supporting portion 111 is lifted to push the second container 23 upward, so that the first opening 231 is in contact with and sealed communication with the water outlet 212.

Based on the structure, the hot beverage machine of the invention can realize the positioning and connection between the first container 21 and the water supply inlet 121 through the first positioning structure, and realize the position positioning between the bearing part 111 and the second container 23 through the second positioning structure 4, so that the water outlet 212 of the first container 21 and the first opening 231 on the second container 23 can be automatically butted after the bearing part 111 is lifted, the assembling operation of a user is reduced, the operation is more convenient, and the user experience is improved.

Specifically, referring to fig. 2 and 4, the first positioning connection structure 3 includes a first threaded portion 31 located at the water supply opening 121 and a second threaded portion 32 located at the water inlet 211, and the first threaded portion 31 and the second threaded portion 32 are matched and screwed to be fixed, that is, the positioning and connection between the water supply opening 121 and the first container 21 are realized by a threaded connection manner, and the threaded connection manner itself has axial positioning, and meanwhile, the connection and the detachment can be considered, and the structure is relatively simple. One of the first thread part 31 and the second thread part 32 is an internal thread, and the other is an external thread. More specifically, the first screw part 31 is a first internal screw provided on the housing 11, the first internal screw being provided around the water supply port 121; the second thread part 32 is a first external thread arranged outside the water inlet 211 of the first container 21, and the first internal thread is matched with the first external thread. That is, the connection and positioning between the water inlet 211 of the first container 21 and the water supply inlet 121 are achieved by the first male screw and the first female screw.

Referring to fig. 2, 4 to 6, on the first container 21, the water outlet 212 is located below the water inlet 211 and is coaxially disposed, the water inlet 211 is axially positioned and connected with the water supply inlet 121, and for installation, the water outlet 212 and the water inlet 211 are coaxially disposed, so that when the water inlet 211 is connected with the water supply inlet 121, the position of the water outlet 212 is not affected regardless of the tightness of the connection of the first external thread and the first internal thread. If the water outlet 212 is not coaxial with the water inlet 211, when the screwing of the first external thread and the first internal thread is slightly changed, the position of the water outlet 212 is changed along with the rotation of the axis, which is not beneficial to the butt joint and positioning between the second container 23 and the water outlet 212. Therefore, it is necessary to arrange the water outlet 212 coaxially with the water inlet 211.

On the basis that the water outlet 212 and the water inlet 211 are coaxially arranged, the second positioning structure 4 includes a circular recess 41 located on the upper end surface of the supporting portion 111 and a circular convex edge 42 located at the bottom of the second container 23, and the circular convex edge 42 can be fittingly embedded in the circular recess 41; the circular recess 41 is coaxially disposed with the water supply port 121, and the circular rim 42 is coaxially disposed with the first opening 231. Because the circular recess 41 is coaxial with the water supply opening 121, the water supply opening 121 is coaxial with the water inlet 211 and the water outlet 212, and because the circular flange 42 is coaxial with the first opening 231, when the circular flange 42 is installed in the circular recess 41, the circular flange 42 is coaxial with the water outlet 212, that is, the first opening 231 is coaxial with the water outlet 212, and the two are vertically opposite, in this case, as the support part 111 rises, the first opening 231 can be abutted to the water outlet 212. As can be seen from the above structure, when the user mounts the brewing unit 2, the user only needs to screw the first container 21 to the water supply inlet 121, lower the support part 111, place the support part in the second container 23, and then raise the support part 111 to butt the water outlet 212 to the first opening 231 of the second container 23, which is simple to operate.

Preferably, referring to fig. 2 to 6, in order to ensure the sealing effect after the water outlet 212 is abutted with the first opening 231, a circle of first abutting portion 213 is disposed on the periphery of the water outlet 212, a sealing ring 214 is sleeved on the abutting portion 213, and after the supporting portion 111 is lifted to push up the second container 23, the first opening 231 is abutted with and sealed by the sealing ring 214. That is, by providing the abutting portion 213 and the packing 214, the sealing connection between the first opening 231 of the second container 23 and the water outlet 212 is ensured.

In addition, the upper end of the second container 23 is further provided with a second opening 232, the second opening 232 is used for exhausting air, because the first opening 231 is hermetically connected with the water outlet 212, hot water with micro pressure discharged from the water supply port 121 enters the second container 23 after passing through the first container 21 and the filter assembly 22, and gas brought by the hot water can be discharged through the second opening 232, so that the influence on the water discharging function due to the fact that the pressure in the container is higher and higher is avoided. Furthermore, after the beverage preparation is completed, drinking can also be performed directly through the second opening 232. Preferably, the second opening 232 extends upwardly to be convex.

Based on the structure, the hot beverage machine can realize the basic brewing function, solid raw materials are placed in the first container 21, hot water is slowly added through the water supply mechanism 12, the hot water is used for brewing the solid raw materials and is filtered by the filtering component 22, finally, brewed beverages enter the second container 23, and after all the beverages in the first container 21 are discharged into the second container 23, the second container 23 can be taken down for drinking.

On the basis, referring to fig. 2, 9 to 11, the brewing assembly 2 further comprises a siphon tube 24, the siphon tube 24 is vertically through, the lower end of the siphon tube 24 can be inserted into the first opening 231, and a gap is formed between the lower end of the siphon tube 24 and the bottom of the second container 23; a second abutting portion 241 is provided at an upper end opening of the siphon tube 24, the second abutting portion 241 is bridged over the first opening 231 and is hermetically connected to the first opening 231, the second abutting portion 241 abuts against and is hermetically sealed to the first abutting portion 213, and the water outlet 212 communicates with the upper end opening of the siphon tube 24. After the siphon tube 24 is inserted into the first opening 231, it is hermetically connected to the first opening 231 and the water outlet 212, and a tube leading to the bottom of the second container 23 is added on the original basis. By adding the siphon pipe 24, the function of siphon extraction can be realized, and the principle of the function of specific siphon extraction can refer to the application numbers in the prior art as follows: 201911122117.6 entitled Hot beverage brewing mechanism, Hot beverage maker, and Hot beverage brewing method, which are not further detailed herein.

Preferably, the first and second containers 21 and 23 are transparent, so that the user can observe the inside of them to know the degree of brewing.

Specifically, referring to fig. 4 to 6, the first container 21 includes a first cup 215 and a bottom cover 216, the first cup 215 is cylindrical, the upper end opening of the first cup 215 is the water inlet 211, the water outlet 212 is disposed on the bottom cover 216, correspondingly, a first abutting portion 213 is also disposed on the bottom cover 216 and is located on the bottom surface of the bottom cover 216, and the bottom cover 216 is in threaded connection with the lower end opening of the first cup 215. The first container 21 is formed by the first cup 215 and the bottom cover 216, and the first cup 215 and the bottom cover 216 are screwed together and can be disassembled for cleaning.

The filter assembly 22 is located at the lower end opening of the first cup 215 and clamped between the bottom cover 216 and the first cup 215, the filter assembly 22 is fixed between the water inlet 211 and the water outlet 212 through the threads of the first cup 215 and the bottom cover 216, and the beverage discharged from the water outlet 212 is filtered, so that the drinking taste of the beverage is improved.

Specifically, referring to fig. 5 to 8, the filter assembly 22 includes a filter element 221 and a bracket 222 for supporting the filter element 221, the bracket 222 includes a clamping ring 2221 and a support portion 2222 extending from the clamping ring 2221 to the middle, and the filter element 221 is located on the support portion 2222; after the bottom cap 216 and the first cup 215 are connected, the clamping ring 2221 and the filter element 221 are clamped between the lower rim of the first cup 215 and the bottom cap 216. The support 222 supports the filter element 221, because the filter element 221 generally employs filter paper 2211, filter screen 2212 or filter cloth, and these 3 are not strong enough, if the amount of solid material added into the first container 21 is large and the solid material is brewed by water flow, the filter element 221 may deform to generate gaps, complete filtration cannot be achieved, and the taste of the beverage is reduced. For this reason, the bracket 222 is provided to prevent the filter member 221 from being deformed and leaking.

Preferably, with reference to fig. 5-8, the filter element 221 is upwardly convex and extends into the first cup 215. During the brewing of the beverage, the brewing material is in the first cup 215, which is above the first cup 215 in use, so that the filtered material residue remains above the filter element 221. If the filter member 221 is recessed downward, the residue is in the recessed surface, and it is difficult to clean the residue in the recessed surface when the filter member is used and cleaned. In the scheme, the filtering piece 221 is arranged to be convex upwards, so that filter residues are on the convex surface, the filtering piece can be conveniently cleaned, and residues are reduced. Naturally, the filter member 221 is upwardly convex, and the support portion 2222 is also upwardly convex in order to support it. Specifically, the filtering member 221 is in a conical shape or a circular truncated cone shape, has a large filtering area, and protrudes upward, and the supporting portion 2222 is adapted to the shape of the filtering member 221, that is, in a conical shape or a circular truncated cone shape, so as to maintain the support of the filtering member 221.

As mentioned above, the filter 221 may be a filter paper 2211 or a filter 2212, and specific arrangements of these two cases are as follows.

The annular flange 22111 abuts the clamp ring 2221 and clamps the annular flange 22111 of the filter paper 2211 together when the first cup 215 and the bottom bar clamp the clamp ring 2221, thereby securing the filter paper 2211.

As shown in fig. 8, when the filter 221 is a filter screen 2212, the bracket 222 includes an inner housing 2223 and an outer housing 2224, the inner housing 2223 and the outer housing 2224 are tapered and nested together, and the filter screen 2212 is sandwiched between the inner housing 2223 and the outer housing 2224. The screen 2212 is clamped together by the mating of the inner housing 2223 and the outer housing 2224.

Preferably, in order to ensure the sealing effect of the bottom cover 216 and the first cup 215 after clamping the filter assembly 22, an annular sealing collar 223 is sleeved outside the clamping ring 2221, and the lower end rim of the first cup 215 and the bottom cover 216 are respectively in sealing engagement with the upper end face and the lower end face of the annular sealing collar 223. The sealing effect between the first cup 215, the filter assembly 22 and the bottom cover 216 is enhanced by the annular sealing ring 214, and air leakage and water leakage are avoided.

With reference to fig. 9 to 11, the second container 23 includes a second cup 233 and a top cover 234, the first opening 231 is disposed on the top cover 234, the top cover 234 is screwed with the second cup 233, and also has a positioning and connecting function, and the top cover 234 and the second cup 233 can be detached by screwing, so as to be convenient for cleaning, preferably, the upper end edge of the first opening 231 is rolled outwards to form a ring of abutting edge 2311, and the abutting edge 2311 abuts against the water outlet 212, so as to further improve the sealing performance of the connection between the first opening 231 and the water supply port 121. A second opening 232 is also provided in the top cover 234. A sealing ring is provided between the second cup 233 and the lid 234 to ensure sealing.
