Referring to fig. 1-2, fig. 1 is a schematic overall structure diagram of an embodiment of a coffee machine provided by the present application, fig. 2 is a schematic internal structure diagram of the embodiment of the coffee machine shown in fig. 1, and a coffee machine 10 of the present embodiment includes a powder bowl mechanism 100, a bean grinding mechanism 200, a pressing mechanism 300, and an extraction mechanism 400. Wherein, the powder bowl mechanism 100 includes the powder bowl 11, and in practical application, the powder bowl 11 can make a round trip to move along predetermineeing the track to respectively with powder bowl mechanism 100, grind beans mechanism 200, hold-down mechanism 300 and extraction mechanism 400 cooperation, realize grinding beans, bean flour sticiss and coffee extraction's whole action flow.

Because the powder bowl 11 is respectively matched with the bean grinding mechanism 200, the pressing mechanism 300 and the extracting mechanism 400, after the whole action flow of bean grinding, bean powder pressing and coffee extracting is realized, bean powder and/or a mixture of the bean powder and water can be attached to the inner wall and the outer wall of the powder bowl 11, and time and labor are wasted when the powder bowl is manually cleaned. In view of the above problem, the coffee maker 10 of the present embodiment further includes a cleaning mechanism 500, the cleaning mechanism 500 is correspondingly disposed at a fourth preset position of the preset track, and when the powder bowl 11 moves to the fourth preset position along the preset track, the cleaning mechanism 500 can clean the inner wall and the outer wall of the powder bowl 11.

Considering that when the extraction mechanism 400 is matched with the powder bowl 11, the extraction mechanism 400 performs high-temperature high-pressure extraction on the bean powder contained in the powder bowl 11 to obtain coffee, therefore, the material of the powder bowl 11 can be a high-temperature and high-pressure resistant metal material; in the coffee extraction process, in order to fully extract the bean flour in the powder bowl 11 by the high-temperature and high-pressure water flow to ensure the quality of the coffee, a filter screen (not shown) can be arranged on the bottom wall of the powder bowl 11, so that the high-temperature and high-pressure water flow can flow out of the filter screen after the bean flour in the powder bowl 11 is extracted.

Moreover, in order to further facilitate the matching of the powder bowl 11 and the pressing mechanism 300 or the extracting mechanism 400, the pressing mechanism 300 is favorable for uniformly pressing the bean flour in the powder bowl 11 or the extracting mechanism 400 is favorable for sufficiently extracting the bean flour in the powder bowl 11 to obtain high-quality coffee, and the powder bowl 11 may be a hollow cylinder.

In order to make the overall layout of the coffee maker 10 more compact and facilitate the flow operation to obtain the coffee with good quality, the bean grinding mechanism 200, the pressing mechanism 300, the extracting mechanism 400 and the cleaning mechanism 500 in the embodiment can be sequentially arranged side by side, so that the powder bowl 11 can move back and forth on the preset track to be respectively matched with the bean grinding mechanism 200, the pressing mechanism 300, the extracting mechanism 400 and the cleaning mechanism 500, and the discharging efficiency of the high-quality coffee is improved.

In order to facilitate the matching of the powder bowl mechanism 100 with the bean grinding mechanism 200, the compacting mechanism 300, the extracting mechanism 400 and the washing mechanism 500 at different preset positions of the preset track, specifically refer to fig. 3, fig. 3 is a schematic structural diagram of the powder bowl mechanism in the coffee machine provided by the present application, the powder bowl mechanism 100 in this embodiment includes a slide rail 12, a lifter 13, a powder bowl 11, a first translational driving member, a second translational driving member and a rotational driving member (not shown), the lifter 13 is slidably disposed on the slide rail 12, the powder bowl 11 is rotatably disposed on the lifter 13, and the first translational driving member, the second translational driving member and the rotational driving member are used for adjusting relative positions between the powder bowl 11 and the bean grinding mechanism 200, the compacting mechanism 300, the extracting mechanism 400 or the washing mechanism 500 to be matched.

Specifically, when the powder bowl 11 needs to be matched with any one of the bean grinding mechanism 200, the pressing mechanism 300, the extracting mechanism 400 and the cleaning mechanism 500, the first translation driving member integrally drives the lifter 13 and the powder bowl 11 to slide on the sliding rail 12 along the first direction, the second translation driving member drives the powder bowl 11 to translate along the second direction, and the rotary driving member drives the powder bowl 11 to rotate by taking the central axis of the powder bowl 11 as a rotating axis, so that the powder bowl 11 is matched with the bean grinding mechanism 200.

With continuing reference to fig. 4-6, fig. 4 is a schematic diagram of the overall structure of the bean grinding mechanism provided herein, fig. 5 is a schematic diagram of a partially exploded structure of the grinding element of the bean grinding mechanism shown in fig. 4, and fig. 6 is a schematic diagram of a partially exploded structure of the grinding element of the bean grinding mechanism shown in fig. 4. The bean grinding mechanism 200 of the present embodiment includes a grinding assembly 210, a drive assembly 220, and a condensing assembly 230. Wherein, grinding component 210 includes bean storehouse 211 and the grinding piece 212 for holding the coffee beans, and grinding piece 212 includes grinding space 213, and grinding piece 212 connects drive assembly 220, and condensing unit 230 includes condenser pipe 231, and condenser pipe 231 pastes and locates on grinding piece 212.

In this embodiment, the grinding member 212 is driven by the driving assembly 220 to grind the coffee beans falling into the grinding space 213 from the bean outlet hole (not shown) of the bean bin 211, so as to provide enough bean flour for coffee making, thereby avoiding poor quality of the produced coffee due to insufficient bean flour; because the temperature around the grinding piece 212 rises when the grinding piece 212 grinds coffee beans, the arrangement that the condensation pipe 231 is attached to the grinding piece 212 reduces the temperature of the grinding piece 212 in the process of grinding the coffee beans to form the bean powder, and the influence on the quality of the coffee product caused by overhigh temperature is avoided.

Considering that the polishing element 212 of the present embodiment is disposed in the polishing housing 214, in order to improve the cooling effect of the condensation pipe 231 on the polishing element 212, the condensation pipe 231 of the present embodiment penetrates through the polishing housing 214 to be disposed close to the polishing element 212, the polishing housing 214 includes a receiving cavity 2141 and a through hole 2142, the polishing element 212 is received in the receiving cavity 2141, and the condensation pipe 231 is attached to the polishing element 212 through the through hole 2142. In one embodiment, the through hole 2142 is as close as possible to the polishing element 212.

In order to improve the cooling effect of the condensation pipe 231 on the polishing member 212, the bottom of the accommodating cavity 2141 is circumferentially provided with two through holes 2142 in the embodiment, so as to achieve a better cooling effect by increasing the contact area between the condensation pipe 231 and the polishing member 212.

Further, in consideration of the recycling problem of the condensate in the condensation pipe 231, the condensation pipe 231 of the present embodiment is of a "U-shaped structure", and the condensation pipe 231 of the "U-shaped structure" includes a first section (not shown), a U-shaped section 2311 and a second section (not shown), the first section and the second section are respectively disposed in the two through holes 2142, and the U-shaped section 2311 is attached to the grinding housing 214. Specifically, one end of the first section of the condensation pipe 231 is connected to a condensation system (not shown) of condensate, the other end is connected to one end of the U-shaped section 2311 through the through hole 2142, one end of the second section of the condensation pipe 231 is connected to the condensation system of condensate, and the other end is connected to the other end of the U-shaped section 2311. The condensing system is used for accommodating condensate and cooling the condensate which circulates back to the condensing system. In other embodiments, the condensation pipe 231 may be connected to the cleaning mechanism 500 to use the condensate for reducing the temperature of the grinding member 212 to clean the powder bowl 11.

The grinding member 212 in this embodiment includes a grinding cutter 2121 and a fixed cutter 2122, which are disposed opposite to each other, the grinding cutter 2121 includes a plurality of first grinding teeth (not shown) disposed along a circumferential direction, the fixed cutter 2122 includes a plurality of second grinding teeth (not shown) disposed along the circumferential direction, the plurality of first grinding teeth and the plurality of second grinding teeth are disposed opposite to each other to form a grinding space 213, and the first grinding teeth and the second grinding teeth face opposite to each other along the circumferential direction. In practice, when the drive assembly 220 drives the grinding member 212 to grind coffee beans in the grinding space 213, the stationary cutter 2122 does not rotate, and the first plurality of grinding teeth of the grinding cutter 2121 cooperate with the second plurality of grinding teeth of the stationary cutter 2122 to grind coffee beans in the grinding space 213 as the drive assembly 220 rotates. The cutter gap between the grinding cutter 2121 and the fixed cutter 2122, which are arranged oppositely, may be set according to actual conditions, which is not limited in this embodiment.

The fixed cutter 2122 is provided on the side of the grinding cutter 2121 away from the condenser pipe 231. In order to facilitate the coffee beans in the bean pod 211 to fall straight into the grinding space 213, the stationary cutter 2122 is provided as an annular disc, and the stationary cutter 2122 includes a grinding inner passage (not shown) communicating with the grinding space 213, so that the coffee beans in the bean pod 211 fall into the grinding space 213 via the grinding inner passage provided in correspondence with the bean outlet hole.

Considering that a user may make coffee with different kinds of beans, if there is only one bean bin 211 and one grinding member 212 corresponding to the bean bin 211, the user needs to take out the unground beans in the bean bin 211 to be able to put other beans in for making coffee. In order to enhance the user experience, the grinding assembly 210 of the present embodiment at least includes two bean bins 211 and two grinding members 212 corresponding to the two bean bins 211, and the two grinding members 212 are used for holding different types of coffee beans.

The two grinding members 212 grind the coffee beans in the grinding space 213 into bean powders under the drive of the same drive assembly 220. Further, considering that the plurality of first gears of the grinding cutter 2121 and the plurality of second gears of the stationary cutter 2122 in the same grinding member 212 are oriented in opposite directions in the circumferential direction, it is possible that two grinding members 212 of the present embodiment will grind coffee beans in the respective bean cartridge 211 simultaneously when the two grinding members 212 grind coffee beans in the grinding space 213 under the drive of the same drive assembly 220.

In order to avoid the above situation, in the present embodiment, the first teeth of the grinding cutterhead 2121 of one grinding member 212 and the first teeth of the grinding cutterhead 2121 of the other grinding member 212 of the two grinding members 212 are opposite in orientation in the circumferential direction, even if the same driving assembly 220 drives the two grinding members 212 to rotate and grind simultaneously, only one grinding member 212 of the two grinding members 212 performs grinding, and although the grinding cutterhead 2121 of the other grinding member 212 rotates along with the driving assembly 220, because the rotation direction of the grinding cutterhead 2121 is the same as the direction of the second gear of the fixed cutterhead 2122, the grinding cutterhead 2121 and the fixed cutterhead 2122 in the other grinding member 212 do not have the function of grinding coffee beans by matching gears.

Further, in practical applications, it may be desirable to make coffee from coffee beans in two bean silos 211, such that the coffee beans placed in both bean silos 211 need to be ground, and the two grinding members 212 are driven by the same driving assembly 220, resulting in that the coffee beans in both bean silos 211 cannot be ground simultaneously. In view of the above, the driving assembly 220 of the present embodiment can periodically perform forward and backward rotation to grind the coffee beans in the two bean silos 211. For example, the user sets the driving member 220 to rotate forward 5s and reverse 5s by himself. When the user sets the forward and reverse rotation period of the drive unit 220, the gap between the grinding cutter disc 2121 and the fixed cutter disc 2122 in the grinding tool 212 is constant, and the rotation speed of the drive unit 220 is constant.

And further, because when drive assembly 220 corotation or reversal, grind the coffee beans in different beans storehouse 211 to can place different kinds of coffee beans in different beans storehouse 211, grind and form different soybean meal, and predetermine corotation and the time ratio of reversal, thereby obtain the soybean meal proportion that corresponds, thereby realize automatic ratio to the soybean meal, satisfy different ratio demands, with the taste quality that promotes coffee.

Further, in order to guide the ground bean powder to fall into the powder bowl 11 matched with the bean grinding mechanism 200, the grinding assembly 210 of the present embodiment further includes a powder outlet channel 215, and the powder outlet channel 215 is communicated with the grinding spaces 213 of the two grinding members 212, so that the ground bean powder falls into the powder bowl 11 through the powder outlet channel 215.

For this reason, in the embodiment, the powder distributing sheet 216 is disposed in the powder outlet channel 215, and the powder distributing sheet 216 is rotatably accommodated in the powder outlet channel 215 by taking an axis parallel to the length direction of the powder outlet channel 215 as a rotating shaft.

In practical application, when the powder bowl 11 needs to be matched with the bean grinding mechanism 200, the first translational driving member integrally drives the lifter 13 and the powder bowl 11 to slide on the sliding rail 12 to be located at the fifth preset position, the second translational driving member drives the powder bowl 11 to be close to the powder outlet channel 215 to enter the first preset position, and the powder outlet channel 215 provides the bean powder to the powder bowl 11, so that the powder bowl 11 is matched with the bean grinding mechanism 200.

When the powder bowl 11 is matched with the bean grinding mechanism 200, the powder bowl 11 and the powder outlet channel 215 are correspondingly arranged, the powder distribution piece 216 is suspended at the opening of the powder bowl 11, the bean flour formed by grinding by the grinding piece 212 falls into the powder bowl 11 through the powder outlet channel 215, and the powder distribution piece 216 rotates and paves the bean flour falling into the powder bowl 11 by taking an axis parallel to the length direction of the powder outlet channel 215 as a rotating shaft, so that when the bean flour falls into the powder bowl 11, the bean flour is easy to form a conical stack and exceeds the opening plane of the powder bowl 11, the bean flour in the powder bowl 11 falls in the subsequent moving process, and the subsequent compressing mechanism 300 is not favorable for compressing the bean flour in the powder bowl 11. The specific structure of the powder distribution sheet 216 can be seen in fig. 6.

Referring still to fig. 7-8, fig. 7 is a schematic diagram of an overall structure of a cleaning mechanism provided herein, and fig. 8 is a schematic diagram of an exploded structure of a cleaning assembly in the cleaning mechanism shown in fig. 7. The washing mechanism 500 of the present embodiment includes a washing assembly 510 for washing the powder bowl 11. Wherein the washing assembly 510 includes a water supply member 51 provided with a water outlet 511, and the water supply member 51 is connected with the washing driving member 52.

When the washing mechanism 500 is matched with the powder bowl 11, the water feeding member 51 is used for embedding in the powder bowl 11 and spraying or sprinkling washing liquid towards the powder bowl 11, and the washing driving member 52 is used for driving the water feeding member 51 to rotate relative to the powder bowl 11 so as to wash the powder bowl 11.

The cleaning assembly 510 of this embodiment further includes a rotating impeller 53 connected to the cleaning driving member 52, the rotating impeller 53 is sleeved on the water supply member 51, when the cleaning mechanism 500 is engaged with the powder bowl 11, the rotating impeller 53 is located in the powder bowl 11, and the cleaning driving member 52 is used for driving the rotating impeller 53 to rotate relative to the powder bowl 11 to clean the powder bowl. It can be understood that the cleaning driving member 52 drives the rotating impeller 53 to rotate and drive the cleaning liquid sprayed into the powder bowl 11 by the water feeding member 51 to rotate in the rotating impeller 53, so that the cleaning liquid with a rotating speed rotates on the inner wall of the powder bowl 11, and friction is generated between the cleaning liquid and the inner wall of the powder bowl 11 to clean the powder bowl 11, thereby improving the cleaning force of the cleaning mechanism 500 on the powder bowl 11. The cleaning liquid can be water, detergent or a mixture of water and detergent.

In order to facilitate the washing liquid with the rotating speed to wash the powder bowl 11 more thoroughly, the water supply member 51 should be as close to the bottom wall of the powder bowl 11 as possible, so that the washing liquid sprayed from the water supply member 51 is driven by the rotation of the rotating impeller 53 to start to rotate from the bottom wall of the powder bowl 11 to wash the powder bowl 11, and therefore, the water outlet 511 of the water supply member 51 should protrude out of the rotating impeller 53.

Considering that the cleaning liquid sprayed from the water feeding member 51 is driven by the rotating impeller 53 to rotate when the powder bowl 11 is cleaned, the cleaning liquid is discharged along the outer wall of the rotating impeller 53 along with the rotation of the rotating impeller 53, for this reason, when the cleaning mechanism 500 is engaged with the powder bowl 11 in this embodiment, a gap exists between the outer wall of the rotating impeller 53 and the sidewall of the powder bowl 11, so that when the cleaning driving member 52 drives the rotating impeller 53 to rotate, the cleaning liquid in the powder bowl 11 is discharged through the gap along with the rotation of the rotating impeller 53.
