Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] For example, see Figure 1-6A flow valve core assembly of a coffee machine comprises a flow valve body 1, a connecting pipe 11 is fixedly installed on the top of the flow valve body 1, and the connecting pipe 11 is connected to the inside of the flow valve body 1, a rotating rod 15 is rotatably connected to the inside of the flow valve body 1, a plurality of evenly distributed slots 16 are opened on the surface of the rotating rod 15, a filter assembly 2 is slidably inserted into the rotating rod 15 through the plurality of slots 16, and the filter assembly 2 comprises two fine filter screens 21, two closing plates 22 and two coarse filter screens 23, one end of each of the fine filter screens 21, the closing plate 22 and the coarse filter screen 23 is fixedly installed with an insert block 24, and the plurality of insert blocks 24 are respectively slidably connected to adjacent slots 16, and the apertures of the two fine filter screens 21 are smaller than the apertures of the two coarse filter screens 23 The other end of each fine filter screen 21, the closing plate 22 and the coarse filter screen 23 is fixedly installed with a second sealing strip 25. Two first sealing strips 17 are also arranged in the inner wall of the flow valve body 1. The two second sealing strips 25 located on the same axis as the first sealing strip 17 are respectively interference-engaged on the first sealing strip 17. The other end of the connecting pipe 11 is connected to the inside of the coffee machine. A flow sensor is arranged inside the connecting pipe 11. A liquid outlet pipe 12 is fixedly installed at the bottom of the flow valve body 1. The liquid outlet pipe 12 is connected to the inside of the flow valve body 1. A fixed block 13 is also fixedly installed at one end of the flow valve body 1. The end of the rotating rod 15 close to the fixed block 13 is rotatably connected to the fixed block 13. The fixed block 13 is rotatably connected with an adjusting component 3.

[0026] In the initial state, the two closing plates 22 in the flow valve body 1 are in contact with the two first sealing strips 17, so that the flow valve body 1 is sealed. When it is needed, the rotating rod 15 is rotated by the adjusting component 3, so that the rotating rod 15 drives the filter component 2 to rotate, so that the two closing plates 22 are moved out from the first sealing strip 17, and the two fine filter screens 21 or the two coarse filter screens 23 are rotated to abut against the first sealing strip 17 as needed, and the coffee machine is started to extract. The extracted coffee liquid enters the flow valve body 1 through the connecting pipe 11, and the coffee liquid is filtered again by the fine filter screen 21 or the coarse filter screen 23 to make the outflowing coffee liquid more delicate. The filtered coffee liquid flows out through the liquid outlet pipe 12;

[0027] By providing two first sealing strips 17, the tightness of the connection can be increased during use to prevent coffee liquid from flowing out of the gap.

[0028] For example 2, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The adjusting component 3 includes a rotating handle 31, one end of which is connected to the rotating rod 15 inside the fixed block 13 through a connecting shaft, and a connecting plate 32 is fixedly installed on the other end of the rotating handle 31, and a plug rod 33 is slidably connected to the end of the connecting plate 32 away from the rotating handle 31, and a pull plate 34 is fixedly installed on the top of the plug rod 33, and a reset spring 35 is fixedly installed on the side of the pull plate 34 close to the connecting plate 32, and the other end of the reset spring 35 is fixedly installed in the connecting plate 32, and a plurality of evenly distributed limiting holes 14 are opened on the surface of the side of the flow valve body 1 close to the adjusting component 3, and the plug rod 33 is slidably engaged in the adjacent limiting holes 14;

[0029] When the filter assembly 2 needs to be adjusted during use, the pull plate 34 is first pulled to make the pull plate 34 drive the insertion rod 33 to slide upward, so that the insertion rod 33 is moved out of the limiting hole 14. After it is completely moved out, the rotating handle 31 is rotated to make the rotating handle 31 drive the rotating rod 15 to rotate, thereby adjusting the filter assembly 2 on the rotating rod 15. The spacing between two adjacent limiting holes 14 is the same as the spacing between the fine filter screen 21 and the fine filter screen 21 and the closing plate 22. Therefore, when the insertion rod 33 is rotated to another limiting hole 14, the position of the filter assembly 2 is just replaced.

[0030] When the filter layer to be used is moved to abut against the first sealing strip 17, the pull plate 34 is released, and the pull plate 34 and the insertion rod 33 are driven to rebound downward under the action of the rebound force of the reset spring 35, so that the insertion rod 33 is inserted into the adjacent limiting hole 14, so that the rotating handle 31 and the rotating rod 15 are fixed, thereby fixing the filter assembly 2.

[0031] For example 3, please refer to Figure 1 and Figure 4 , two sliding grooves 18 are symmetrically provided on one end of the flow valve body 1 away from the fixed block 13, and the flow valve body 1 is slidably clamped with a sealing cover 4 through the sliding groove 18, and a sealing block 41 is fixedly installed on the side of the sealing cover 4 close to the flow valve body 1, and two third sealing strips 42 with the same position as the sliding groove 18 are symmetrically installed on the sealing block 41, and the two third sealing strips 42 are respectively slidably clamped in the adjacent sliding grooves 18, and a pull block 43 is also fixedly installed on the side of the sealing cover 4 away from the flow valve body 1;

[0032] When there are too many coffee grounds on the filter assembly 2, the pull block 43 is pulled so that the pull block 43 drives the sealing cover 4 and the sealing block 41 to be removed from the flow valve body 1, so that the two third sealing strips 42 are removed from the two sliding grooves 18, and the filter layer to be cleaned is rotated to the position of the two sliding grooves 18 by rotating the handle 31, and the filter assembly 2 to be cleaned is taken out through the sliding groove 18;

[0033] By means of the provided sealing cover 4, the filter assembly 2 can be removed from the flow valve body 1 during use, so that the filter assembly 2 can be replaced or cleaned conveniently to avoid blockage of the filter assembly 2 and the influence on the normal liquid discharge. Meanwhile, by means of the provided sealing block 41 and the third sealing strip 42, the flow valve body 1 can be sealed to avoid liquid leakage.

[0034] Working principle: In the initial state, the two closing plates 22 in the flow valve body 1 are in contact with the two first sealing strips 17, so that the flow valve body 1 is sealed. When it is needed, the pull plate 34 is pulled to make the pull plate 34 drive the insertion rod 33 to slide upward, so that the insertion rod 33 is moved out of the limit hole 14. After it is completely moved out, the rotating handle 31 is rotated to make the rotating handle 31 drive the rotating rod 15 to rotate, so that the rotating rod 15 drives the filter assembly 2 to rotate, so that the two closing plates 22 are moved out from the first sealing strip 17, and the two fine filter screens 21 or the two coarse filter screens 23 are rotated to abut against the first sealing strip 17 as needed, and the coffee machine is started for extraction. The extracted coffee liquid enters the flow valve body 1 through the connecting pipe 11, and the coffee liquid is filtered again by the fine filter screen 21 or the coarse filter screen 23 to make the outflowing coffee liquid more delicate. The filtered coffee liquid flows out through the liquid outlet pipe 12;

[0035] When there are too many coffee grounds on the filter assembly 2, pull the pull block 43 so that the pull block 43 drives the sealing cover 4 and the sealing block 41 to be removed from the flow valve body 1, so that the two third sealing strips 42 are removed from the two sliding grooves 18, and the filter layer to be cleaned is rotated to the position of the two sliding grooves 18 by turning the handle 31, and the filter assembly 2 to be cleaned is taken out through the sliding groove 18.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
