[0002] A coffee machine is a machine used to brew coffee. Coffee machines can be divided into pressure coffee machines and drip coffee machines according to the pressure. Pressure coffee machines are popular because the coffee brewed by them has a mellow taste.

[0003] At present, most of the funnel assemblies in traditional pressure coffee machines adopt a rotating funnel structure, that is, the bracket of the coffee machine is interlocked with each other through a plurality of bosses on the edge of the funnel mouth. During its installation, it is first necessary to match the position of the boss with the position of the coffee machine bracket, and then forcefully rotate the funnel assembly to achieve the effect of fixing the funnel assembly. However, this fixing method of the funnel assembly, on the one hand, not only needs to rotate the funnel to a certain angle first so that the boss is stuck in the bracket, but also needs to rotate the funnel to fix the funnel assembly; on the other hand, in the process of inserting the boss into the bracket, the user also needs to constantly adjust the position of the funnel so that the boss is stuck in place, which causes the problem of inconvenience in fixing the funnel assembly.

[0029] The following is combined with the accompanying drawings of the specification Figure 1-Figure 5 This application is described in further detail.

[0030] Reference Figure 1 The embodiment of the present application discloses a funnel installation structure of a coffee machine, the funnel installation structure comprising a funnel assembly 1, a placement module 2 and a pressing module 4. The placement module 2 is used to install and fix the funnel assembly 1, the pressing module 4 is used to press the funnel assembly 1 and form a sealed coffee brewing chamber with the funnel assembly 1, and external hot water enters the coffee brewing chamber through the pressing module 4 to complete the coffee brewing.

[0031] The placement module 2 is provided with a brewing through hole 21 that cooperates with the funnel assembly 1. The funnel assembly 1 includes an extraction funnel 11 and a handle 12 that is fixedly connected to the extraction funnel 11. Blocks 111 are symmetrically arranged on both sides of the funnel opening at the top of the extraction funnel 11. A card entrance is provided on one side of the placement module 2, and card insertion guide grooves 22 are arranged on both sides of the card entrance. When installing the funnel assembly 1, the two card blocks 111 of the funnel assembly 1 are overlapped to the card insertion guide grooves 22 respectively, and the funnel assembly 1 is pushed by the handle 12, so that the extraction funnel 11 slides along the card insertion guide grooves 22 and is inserted into the brewing through hole 21, and then the pressing module 4 is pressed against the extraction funnel 11 from above the brewing through hole 21 to form the brewing chamber with the extraction funnel 11.

[0032] Since the single-side clip-in fixing method is adopted, the extraction funnel 11 only needs to be fixed by sliding along the clip-in guide groove 22 , thereby improving the convenience of installing the funnel assembly 1 .

[0033] Reference Figure 2 and Figure 3 , a snap-fitting structure snap-fitting with the snap-fitting block 111 is arranged in the placement module 2. In a preferred embodiment, snap-fitting guide grooves 23 are symmetrically provided in the placement module 2, and the snap-fitting guide grooves 23 are communicated with the snap-in guide grooves 22. The snap-fitting structure comprises a seesaw 24, and a rotating block 26 is connected to the middle position of the seesaw 24 through a wave point spring 25, and the rotating block 26 is rotatably connected to the snap-fitting guide groove 23. A limiting hole 241 is arranged on the side of the seesaw 24 facing the rotating block 26, and the wave point spring 25 is located in the limiting hole 241, and one end of the rotating block 26 is inserted into the limiting hole 241 and elastically slidably connected to the limiting hole 241 through the wave point spring 25, and one end of the seesaw 24 facing the snap-in guide groove 22 is connected to the side wall of the snap-fitting guide groove 23 through a reset tension spring 27.

[0034] In the initial state, the reset tension spring 27 is in a natural placement state, and the end of the seesaw 24 away from the insertion guide groove 22 rotates and extends out of the clamping guide groove 23 and enters the brewing through hole 21. When the extraction funnel 11 slides along the insertion guide groove 22 to the clamping guide groove 23, the clamping block 111 of the extraction funnel 11 moves the end of the seesaw 24 away from the insertion guide groove 22, so that the seesaw 24 rotates. The side of the seesaw 24 facing the brewing through hole 21 is provided with a limiting protrusion 242. When the extraction funnel 11 is clamped in place, the limiting protrusion 242 clamps the clamping block 111 to complete the fixing of the extraction funnel 11. At this time, due to the rotation of the seesaw 24, the reset tension spring 27 is in a stretched state.

[0035] When the extraction funnel 11 needs to be removed, the handle 12 is pulled hard so that the block 111 pushes the seesaw 24, and the seesaw 24 compresses the wave-dot spring 25, that is, the two seesaws 24 on both sides of the extraction funnel 11 move away from the extraction funnel 11, so that the extraction funnel 11 is pulled out of the placement module 2, and the seesaw 24 is reset under the action of the reset spring 27.

[0036] In another feasible embodiment, the clamping structure includes a clamping joint disposed in the clamping guide groove 23, and the clamping joint is connected to the clamping guide groove 23 via a wavy spring 25. When the extraction funnel 11 enters the clamping guide groove 23, the clamping joint is pushed by the clamping block 111 so that the clamping joint overcomes the elastic force of the wavy spring 25 and compresses the wavy spring 25, thereby moving the extraction funnel 11 into position. When the extraction funnel 11 is moved into position, the clamping joint pops out under the elastic force of the wavy spring 25, thereby clamping the clamping block 111, and fixing the extraction funnel 11. The matching method of the clamping joint and the wavy spring 25 in this embodiment can refer to the spring jumping bean, and will not be repeated in this application.

[0037] A limiting protrusion 242 is also provided in the clamping guide groove 23. The limiting protrusion 242 and one end of the clamping guide groove 23 facing the clamping guide groove 22 form a tension spring fixing groove connected to the reset tension spring 27. The limiting protrusion 242 and the other end of the clamping guide groove 23 form a rotation limiting groove matched with the rotating block 26. When the extraction funnel 11 is clamped in place, the limiting protrusion 242 abuts against one end of the rotating block 26 away from the seesaw 24, thereby forming a limit to the clamping structure.

[0038] Furthermore, the placement module 2 is also provided with a push rod 31 slidably connected to the placement module 2, the push rod 31 is located at one end of the snap-in guide groove 23 away from the snap-in guide groove 22, one end of the push rod 31 extends into the brewing through hole 21 from the side wall of the brewing through hole 21, and the other end of the push rod 31 is connected to the placement module 2 through a reset spring 33, a trigger protrusion 311 is provided on one side of the push rod 31, and a micro switch 32 is fixedly provided in the placement module 2. When the extraction funnel 11 is snapped into the placement module 2 along the snap-in guide groove 23, the block 111 of the extraction funnel 11 pushes the push rod 31 to overcome the reset spring 33 and move, so that a trigger protrusion 311 of the push rod 31 triggers the micro switch 32, thereby outputting an electrical signal indicating that the extraction funnel 11 is installed in place through the micro switch 32.

[0039] Reference Figure 3 and Figure 4 The bottom of the clamping guide groove 23 is provided with a rotation hole 232, and the rotation block 26 is rotatably connected to the clamping guide groove 23 through the rotation hole 232. Specifically, a rotation shaft (not shown in the figure) is fixedly connected to the side of the rotation block 26, and the rotation block 26 is rotatably connected to the rotation hole 232 through the rotation shaft.

[0040] Reference Figure 4 and Figure 5 In a preferred example, the placement module 2 includes a placement platform 28, the brewing through hole 21 is arranged on the placement platform 28, an annular cover plate 29 matched with the placement platform 28 is arranged above the brewing through hole 21, an annular pressing plate 20 matched with the brewing through hole 21 and the cover plate 29 is arranged above the cover plate 29, and a sealing ring 201 is arranged at the bottom of the pressing plate 20. When the pressing module 4 is pressed into the brewing through hole 21 from top to bottom, it can be sealed with the funnel opening of the extraction funnel 11 through the sealing ring 201 of the pressing plate 20.

[0041] It should be noted that the present application does not make a sole limitation on the sealing method between the pressing module 4 and the extraction funnel 11. For example, in another preferred example, the sealing ring 201 is arranged on the inner wall of the extraction funnel 11. When the pressing module 4 is pressed into the brewing through hole 21 from top to bottom, the pressing plate 20 can be pressed down, thereby sealing with the sealing ring 201 through the end face or outer wall of the pressing plate 20; for another example, in another preferred example, the sealing ring 201 is arranged on the outer wall of the pressing module 4. When the pressing module 4 is pressed into the brewing through hole 21 from top to bottom, it is directly sealed with the extraction funnel 11 through the sealing ring 201.

[0042] The cover plate 29 is provided with a plurality of compression spring fixing holes, in which brewing compression springs 291 are arranged, and the pressing plate 20 is connected to the cover plate 29 via the brewing compression springs 291. When the pressing module 4 presses the pressing plate 20, the pressing plate 20 presses the cover plate 29, and the cover plate 29 overcomes the elastic force of the brewing compression springs 291 and moves downward, thereby sealing the funnel opening of the extraction funnel 11 through the sealing ring 201.

[0043] Furthermore, the compression module 4 includes an extraction head 41 , a pressing plate 42 and a driving rod 43 . The driving rod 43 can slide through the pressing plate 42 and is fixedly connected to the extraction head 41 . A plurality of sealing tension springs 44 are connected between the extraction head 41 and the pressing plate 42 .

[0044] When the compression module 4 and the funnel assembly 1 need to be compressed and sealed, the extraction head 41 is pressed down by the driving rod 43 so that the extraction head 41 and the extraction funnel 11 are sealed. At the same time, the pressing sheet 42 presses down the pressing plate 20 through the tension of the sealing tension spring 44 so that the sealing ring 201 at the bottom of the cover plate 29 is sealed with the funnel mouth of the extraction funnel 11.

[0045] Furthermore, the present application also provides a coffee machine, which is equipped with the funnel mounting structure.

[0046] The working principle of the embodiment of the present application is as follows: when using the coffee machine, the funnel assembly 1 is inserted into the placement module 2 from the insertion guide groove 22 on the side of the placement module 2 to complete the fixing of the funnel assembly 1. When the funnel assembly 1 is fixed, the coffee extraction can be started by pressing and sealing the funnel assembly 1 with the pressing module 4. Compared with the fixing structure of the funnel assembly 1 in the prior art, the present application solution only requires the funnel assembly 1 to be inserted into the placement module 2 from the insertion guide groove 22, which is easy to operate and improves the convenience of installing the funnel assembly 1.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
