The elastic members give the scraping plate 551 a downward movement tendency.

[0047] It should be noted here that the feed unit 5 may be omitted, and only the scraper plate 551 and the side plate 552 may be provided, and the side plate 552 may be directly pivotally or fixedly connected to the shell 1, as long as the scraper plate 551 corresponds to the feed opening position of the shell 1.

[0048] The working principle of the utility model is as follows: Figure 6 and Figure 7 As shown, when the accommodating device 2 is in the first state, the accommodating chamber 211 corresponds to the feed opening of the shell 1 and the lower end position of the funnel portion 51 of the feeding unit 5. At this time, coffee powder and tea powder fall into the feeding port 54 of the feeding unit 5 and then fall into the accommodating chamber 211.

[0049] like Figure 8 As shown, the motion unit 4 drives the first rocker arm 22 to rotate, giving driving force to the accommodating device 2. The protrusion 212 of the accommodating device 2 rotates along the first slide groove 11, causing the accommodating device body 21 to rotate until the accommodating device 2 is in the second state. At this time, the accommodating cavity 211 corresponds to the position of the discharge head 31 of the discharge unit 3.

[0050] like Fig. 9As shown, the motor of the motion unit 4 continues to rotate to drive the first swing rod 22 to rotate. At this time, the protrusion 212 of the accommodating device 2 enters the second slide groove 12. Under the limiting effect of the second slide groove 12, the swing rod 22 rotates to drive the accommodating device body 21 to gradually rise along the second slide groove 12 until the discharge head 31 extends into the accommodating cavity 211. In this process, during the rising process of the accommodating device body 21, the second swing rod 23 also gradually moves up, and the support member 232 of the second swing rod 23 gradually moves from the bottom of the first support portion 13 of the shell 1 to the top of the first support portion 13. The inner side surface of the first support portion 13 is partially The inclined surface is partially in the form of a vertical plane, and the vertical plane is above the inclined surface. The support member 232 is in the form of a sheet. During the upward movement of the second rocker arm 23, the sheet support member 232 slides upward along the inclined surface of the first support portion 13, so that the sheet support member 232 can squeeze through the inner side of the first support portion 13 and move to above the first support portion 13, and the first connecting shaft 223 of the first rocker arm 22 gradually slides from one side of the accommodating device slide groove 220 to the other side. After the accommodating device body 21 rises into place, the discharge head 31 extends into the accommodating chamber 211 to press the coffee powder or tea powder into a cake shape. At this time, the accommodating device 2 is in the third state.

[0051] like Fig.10 As shown, the motor of the motion unit 4 continues to rotate to drive the first swing arm 22 to rotate until the first connecting shaft 223 of the first swing arm 22 slides to the other side of the accommodating device slot 220 and abuts against the baffle 2201. At this time, the first swing arm 22 cooperates with the baffle 2201 and the second slot 12 limits the protrusion 212, so that the accommodating device body 21 is in a locked state. During this period, water is introduced from the water inlet component 215, and the water flows into the accommodating chamber 211 and penetrates through the small holes on the support plate 216. The water is pumped through the discharge pipe 32 by the pump, so that the coffee powder or tea powder in the accommodating chamber 211 is extracted. During the extraction process, since the accommodating device body 21 is in a locked state, even if a large water pressure is generated in the accommodating chamber 211, the accommodating chamber body 21 will not be caused to retreat, thereby ensuring that the coffee powder or tea powder is pressed during extraction and that there is sufficient extraction pressure in the accommodating chamber. At this time, the accommodating device 2 is in the fourth state;

[0052] like Fig.11 and Fig.12 As shown, after the discharge is completed, the motor 41 of the motion unit 4 is reversed, the first connecting shaft 223 is separated from the baffle 2201, and gradually slides to the other side of the receiving device slide groove 220, the receiving device body 21 is unlocked, so that the receiving device body 21 moves down along the second slide groove 12, so that the receiving cavity 211 is separated from the discharge head 31, until the support member 232 of the second swing rod 23 abuts against the upper end of the first support portion 13, and the receiving device 2 is in the fifth state;

[0053] like Fig.13As shown, the accommodating device body 21 continues to move downward with the reverse rotation of the motor 41. Since the support member 232 of the second rocker arm 23 abuts against the upper end of the first support portion 13, the piston is fixed and cannot move further downward. The accommodating chamber 211 continues to move downward relative to the piston, and finally the support plate 216 is flush with the upper surface of the accommodating chamber 211. When the protrusion 212 moves down to the bottom of the second slide groove 12, the support member 232 is also separated from the first support portion 13 and falls back to below the first support portion 13. At this time, the accommodating device 2 is in the sixth state.

[0054] like Fig.14 As shown, the motor 41 of the motion unit 4 is reversed, and then the protrusion 232 enters the first slide groove 11, driving the accommodating device body 21 to rotate. During the rotation, the scraping plate 551 contacts the coffee powder waste or tea powder waste on the top surface of the support plate 216, and can push the coffee powder cake or tea powder cake on the top surface of the support plate 216 to slide along the slide plate 214 and fall into the waste residue box. At the same time, during the rotation of the accommodating device 2, the scraping component 213 of the discharging unit scrapes the bottom surface of the discharging head 31 to scrape off the waste residue remaining on the bottom surface of the discharging head 31. At this time, the accommodating device 2 is in the seventh state;

[0055] The motor 41 of the motion unit 4 is reversed, as Figure 6 and Figure 7 As shown, the motor 41 of the motion unit 4 continues to reverse until the accommodating device 2 returns to the first state. At this time, the protrusion 233 of the second rocker arm 23 abuts against the second support portion 16, so that the rod-shaped portion 231 of the second rocker arm 23 reverses, so that the piston is in a retracted state, waiting for the coffee powder or tea powder to fall in again.

[0056] It can be seen from the above description that, compared with the prior art, the utility model no longer has gears and racks in the accommodating device 2, and its structure is simpler and cost-saving. It also avoids the problem that the gears and racks are easily damaged and difficult to repair, thereby extending the service life of the product. In addition, when the utility model is extracting, the first rocker arm 22 and the accommodating device body 21 are in a locked state, so that the accommodating chamber body 21 is fixed, and the back pressure in the accommodating chamber 211 will not push the piston away, ensuring that the coffee powder or tea powder is pressed tightly enough during extraction and that there is enough pressure in the accommodating chamber, thereby ensuring the taste of the extracted coffee or tea. The utility model is also provided with a scraping component 5 and a scraping component 213 of the discharging unit, which can handle the waste residue more cleanly and thoroughly, and it is more hygienic to use the utility model.

[0057] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
