Description

Coffee machines that accelerate drip filtration Technical Field

[0001] This application belongs to the field of small household appliance technology, and in particular relates to a coffee machine with accelerated drip filtration. Background Technology

[0002] Currently available drip coffee machines are relatively slow and time-consuming to brew coffee. For example, Chinese patent application CN 106943018 A discloses a drip coffee machine comprising a container, a coffee basket, a coffee pot, a temperature-sensing control valve, a control circuit, a switch module, a heating element, and a base. The container holds water for brewing, and the coffee basket contains coffee grounds. When brewing coffee, water flows downwards from the container into the coffee basket, brewing the coffee grounds. The extracted coffee then flows into the coffee pot. This drip coffee machine has a slow brewing speed and struggles to guarantee the extraction rate and concentration of the extracted coffee, resulting in a poor user experience. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide a coffee machine that accelerates drip filtration.

[0004] The technical solution adopted in this application embodiment is an accelerated drip coffee machine, including a body, and the coffee machine further includes:

[0005] A brewing chamber unit is detachably mounted on the body. The brewing chamber unit includes a chamber assembly and a top cover assembly. The chamber assembly has a brewing chamber. The top cover assembly is mounted on the chamber assembly and is used to close or open the upper port of the brewing chamber. The top cover assembly is provided with a powder inlet and a water inlet.

[0006] The coffee powder gate assembly includes a coffee powder gate frame, a sliding module, and a drive mechanism. The coffee powder gate frame is fixed to the machine body and has a coffee powder inlet. When the brewing chamber unit is located on the machine body, the coffee powder inlet is located above the coffee powder inlet. The sliding module is located on the coffee powder gate frame, and the drive mechanism is located on the coffee powder gate frame and connected to the sliding module. The drive mechanism is used to drive the sliding module to move along the coffee powder gate frame to close or open the coffee powder inlet. When the sliding module closes the coffee powder inlet and the brewing water submerges the coffee powder in the brewing chamber, the brewing chamber is in a completely sealed state to maintain low pressure in the brewing chamber during continued brewing.

[0007] The coffee machine of this application embodiment can not only maintain accelerated drip filtration under low pressure, but also has a top cover assembly that can close or open the brewing chamber unit. Compared with the method of using a drive mechanism to push the plunger mechanism to move laterally to cover the brewing chamber, the structure is simple and the cost is low.

[0008] In an optional embodiment, the top surface of the top cover assembly is provided with a flange surrounding the powder inlet; when the sliding module closes the powder inlet, the bottom of the sliding module presses against the flange and generates a preset interference amount with the flange to seal the powder inlet. This ensures sealing performance and improves the sealing effect.

[0009] In an optional embodiment, the top cover assembly includes an upper cover and a lower cover;

[0010] The lower cover is provided with a lower powder inlet channel and an annular cavity surrounding the lower powder inlet channel. The bottom of the annular cavity is provided with a water outlet that communicates with the brewing cavity.

[0011] The upper cover is provided with an upper powder inlet channel, the upper end of which extends through to the top surface of the upper cover and forms the powder inlet. The bottom surface of the upper cover is provided with a connecting part that surrounds the lower port of the upper powder inlet channel and extends downward.

[0012] The upper cover is disposed on the lower cover, and the lower port of the upper powder inlet channel is tightly connected to the upper port of the lower powder inlet channel. The connecting part extends into the annular cavity, and a water cavity is formed between the connecting part and the bottom of the annular cavity. The water cavity is connected to the water supply assembly. A first sealing ring is provided between the inner periphery of the connecting part and the inner wall of the annular cavity; a second sealing ring is provided between the outer periphery of the connecting part and the outer wall of the annular cavity. The top cover assembly has an ingenious structural design, allowing both coffee powder to be added to the brewing chamber and brewing water to be supplied to the brewing chamber without interference between the two.

[0013] In an optional embodiment, the upper cover is provided with a water inlet channel, one end of which communicates with the water chamber, and the other end of which extends to the side of the upper cover and protrudes outward to form a connector. This facilitates connection with the water supply assembly when the brewing chamber unit is installed on the machine frame, enabling smooth water supply.

[0014] In an optional embodiment, the cavity assembly includes:

[0015] The cavity has an open upper end and a closed lower end forming a brewing chamber, and the bottom of the cavity has a coffee liquid outlet communicating with the brewing chamber;

[0016] A filter screen is disposed within the brewing chamber near its bottom.

[0017] A cavity handle, the cavity handle including a first side and a second side opposite to each other and a third side connecting the first side and the second side, so that the cavity handle can be disposed on the circumferential outer side of the cavity in a semi-enclosing manner;

[0018] The first buckle and the second buckle are respectively provided on the first side and the second side, and each includes a protrusion extending toward each other. The protrusion is provided with at least one first protrusion. The first buckle and the second buckle are respectively provided with elastic elements between them and the cavity handle, so that the first buckle and the second buckle can move relative to the cavity handle to move closer to each other and retract inward or move away from each other and expand outward.

[0019] The spring clip is located on the third side and has multiple obliquely arranged guide holes. The first protrusion on the protrusion is correspondingly located in the guide holes. When the spring clip moves downward, it drives the first buckle and the second buckle to retract inward synchronously, and the hooks on the opposite sides of the first buckle and the second buckle are disengaged from the slots of the body. When the spring clip moves upward, it drives the first buckle and the second buckle to expand outward synchronously to extend out of the first side and the second side respectively, and the hooks on the opposite sides of the first buckle and the second buckle are engaged in the slots of the body.

[0020] A reset component is provided at the bottom of the third side and acts on the spring latch to apply a force to the spring latch to move it upward and reset it.

[0021] The cavity assembly of this application can control the synchronous extension and retraction of two latches through spring-loaded latches to achieve a detachable connection with the machine body. Moreover, it is easy to operate. Manually pressing the spring-loaded latches can disengage the latches of the brewing cavity unit from the machine body, and at the same time, holding the handle and pulling it outwards can remove the brewing cavity unit from the whole machine.

[0022] In an optional embodiment, the snap fastener includes a plate-shaped body and a pressing part protruding from the upper outer side of the plate-shaped body, and the reset component is located below the plate-shaped body and acts on the plate-shaped body;

[0023] The plate-shaped body has two sets of guide holes arranged vertically. Each set of guide holes includes two guide holes arranged in a figure-eight shape. The protruding part has two first protrusions, which are respectively located in the two guide holes of the two sets of guide holes that are closest to it. The structure is reasonable and facilitates the simultaneous and smooth outward expansion or inward contraction of the two latches by the spring buckle.

[0024] In an optional embodiment, the top cover assembly has a flange disposed around the powder inlet;

[0025] The sliding module includes a powder door, a powder door bracket, a slanted slider, and a sealing gasket. The slanted slider is located on the outside of the powder door bracket. The powder door is installed inside the powder door bracket. The powder door has a second protrusion that passes through the powder door bracket and extends into the slanted groove on the slanted slider. The bottom of the powder door extends downward out of the powder door bracket. The sealing gasket is fitted onto the bottom of the powder door.

[0026] When the sliding module moves laterally from the position where the powder inlet is open to above the powder inlet, the powder door bracket is limited and held in that position by the powder door frame. The driving mechanism drives the inclined groove slider to continue moving in the lateral direction. The inclined groove of the inclined groove slider pushes the second protrusion of the powder door, causing the powder door to move vertically and toward the powder inlet so that the sealing gasket presses against the flange and generates a preset interference amount with the flange.

[0027] In an optional embodiment, the sliding module further includes a rack plate, which is fixed to the inclined groove slider, and the rack plate is provided with a rack extending laterally;

[0028] The driving mechanism includes a motor connected to a drive gear, which meshes with the rack. When the motor starts, it drives the drive gear to rotate, and the drive gear drives the rack and rack plate to move laterally.

[0029] In an optional embodiment, blind holes are provided on opposite sides of the powder gate bracket parallel to its direction of movement. A column is connected to each blind hole by a spring, and one end of the column protrudes from the blind hole and forms a spherical end, which is used to abut against the powder gate frame or the inclined groove slider. This allows for limiting the movement of the powder gate bracket and the powder gate frame under certain resistance conditions, as well as limiting the movement of the powder gate bracket and the inclined groove slider under certain resistance conditions.

[0030] In an optional embodiment, the brewing chamber is located below the filter screen to form a coffee liquid chamber; a liquid outlet seat is provided at the bottom of the chamber, and a liquid outlet channel is provided in the liquid outlet seat. One end of the liquid outlet channel is connected to the coffee liquid chamber, and the other end of the liquid outlet seat extends out of the liquid outlet seat to form a liquid outlet connector.

[0031] The machine body is equipped with a liquid guide seat, which has an insertion interface. One end of the liquid guide seat communicates with the insertion interface, and the other end of the liquid guide channel is connected to a spout assembly located on the upper part of the machine body via a pipe, allowing the coffee liquid in the coffee chamber to be delivered through the spout assembly. This effectively reduces the height of the coffee machine, achieving overall miniaturization.

[0032] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0033] 1. After the coffee powder falls into the brewing chamber through the powder inlet of the top cover assembly of the brewing chamber unit, the drive mechanism drives the powder door to seal the powder inlet. The hot water supplied by the water supply assembly is sprayed into the brewing chamber through the top cover assembly. When the hot water submerges the coffee powder on the filter screen at the bottom of the brewing chamber, the chamber space is in a completely sealed state. A certain low pressure is formed in the sealed chamber due to the air being pressurized, heated and automatically generated by water vapor, thereby realizing accelerated drip filtration of coffee.

[0034] 2. Press the snap button manually to release the latch between the brewing chamber unit and the main body. At the same time, pull the handle outward to remove the brewing chamber unit from the main body. Flip open the top cover assembly of the brewing chamber unit to empty the residue and clean it. After closing the top cover assembly, push the brewing chamber unit directly into the installation position on the main body to automatically connect with the water supply component, making it easy to disassemble, clean and install.

[0035] 3. The powder door in the powder door assembly can not only move horizontally together with the powder door bracket, but also move downward a short distance after moving horizontally into place, so that the soft rubber sealing gasket on the powder door interferes with the hard rubber flange on the powder inlet of the top cover assembly by a certain amount, thereby forming a good seal.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0066] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0067] This application provides an accelerated drip coffee machine. As shown in Figures 1 to 23, the coffee machine includes a body, a brewing chamber unit 2, and a powder gate assembly 3.

[0068] As shown in Figures 1 and 3, the machine body includes a machine frame 1 and a water supply assembly and a grinding mechanism 16 or a powder loading mechanism disposed on the machine frame 1. The machine frame 1 has a mounting position 11 for setting the brewing chamber unit 2. The bottom of the machine frame 1 has a base 18.

[0069] The brewing chamber unit 2 is detachably mounted on the mounting position 11 of the machine frame 1, as shown in Figures 2 and 3. As shown in Figures 4 and 5, the brewing chamber unit 2 includes a chamber assembly 21 and a top cover assembly 22. The chamber assembly 21 has a brewing chamber 2111, and the top cover assembly 22 is mounted on the chamber assembly 21 and is used to close or open the upper port of the brewing chamber 2111. The top cover assembly 22 has a powder inlet 2212 and a water inlet. The grinding mechanism 16 or the powder loading mechanism adds coffee powder into the brewing chamber 2111 through the powder inlet 2212. The water supply assembly supplies brewing water into the brewing chamber 2111 through the water inlet.

[0070] As shown in Figures 13 and 16, the powder gate assembly 3 includes a powder gate frame 31, a sliding module 32, and a drive mechanism 33. As shown in Figures 19 and 22, the powder gate frame 31 is fixed to the machine body frame 1, and has a powder outlet 311 on it. The powder outlet of the grinding mechanism 16 or the powder loading mechanism passes through the powder outlet 311. When the brewing chamber unit 2 is located on the machine body frame 1, the powder outlet 311 is located above the powder inlet 2212, so that the coffee powder delivered by the powder outlet of the grinding mechanism 16 or the powder loading mechanism can fall into the brewing chamber 2111 through the powder inlet 2212. A sliding module 32 is mounted on the powder gate frame 31, and a drive mechanism 33 is mounted on the powder gate frame 31 and connected to the sliding module 32. The drive mechanism 33 drives the sliding module 32 to move along the powder gate frame 31 to close or open the powder inlet 2212. When the sliding module 32 closes the powder inlet 2212, it keeps the powder inlet 2212 sealed. When the sliding module 32 closes the powder inlet 2212 and the brewing water submerges the coffee powder in the brewing chamber 2111, the brewing chamber 2111 is completely sealed to maintain low pressure during continued brewing. When the powder inlet 2212 is open, coffee powder from the grinding mechanism 16 or the powder outlet channel 161 of the powder loading mechanism can fall into the brewing chamber 2111 through the powder dropper 311 on the top cover assembly 22 (described below) (see Figures 22 and 23).

[0071] In the accelerated drip coffee machine of this embodiment, during the coffee brewing process, the water supply component continuously delivers water to the brewing chamber 2111, and the water supply rate is greater than the outflow rate of the brewed coffee. This causes water to accumulate at the bottom of the brewing chamber 2111. The accumulated water isolates the coffee outlet 2113 from the upper waterless space within the brewing chamber 2111, thus restricting the discharge of gas from the upper waterless space through the coffee outlet 2113. As the liquid level gradually rises, the air pressure in the upper waterless space of the brewing chamber 2111 continuously increases. This air pressure directly acts on the liquid in direct contact with it below, accelerating liquid discharge and increasing the dripping speed. This avoids long waiting times for the user, and the dripping under low pressure improves the taste of the coffee, enhancing the user experience.

[0072] The brewing chamber unit 2 of the accelerated drip coffee machine of this application embodiment is equipped with a top cover assembly 22 that can close or open the brewing chamber 2111. Compared with the method of using the drive mechanism 33 to push the plunger mechanism to move laterally to cover the brewing chamber 2111, the structure is simple and the cost is low. Moreover, the diameter of the powder inlet 2212 is much larger than that of the completely open brewing chamber 2111, making it easier to achieve a seal. This keeps the brewing chamber 2111 sealed and prevents the air in the upper part of the brewing chamber 2111 from leaking through the powder inlet 2212, which would affect the sealing state of the brewing chamber 2111 and prevent low-pressure accelerated drip filtration from being achieved.

[0073] It is understood that the term "low pressure" in this application refers to pressure slightly higher than the external atmospheric pressure. The specific pressure value is not limited and is determined by the difference between the water supply rate of the water supply component and the dripping rate.

[0074] In some embodiments, as shown in Figures 6 to 9, the top surface of the top cover assembly 22 is provided with a flange 2213 surrounding the powder inlet 2212. When the sliding module 32 closes the powder inlet 2212, the bottom of the sliding module 32 presses against the flange 2213, and a preset interference amount is generated between the sliding module 32 and the flange 2213 to seal the powder inlet 2212. The powder inlet 2212 is sealed by a certain amount of interference between the flange 2213 and the sliding module 32, achieving an excellent sealing effect.

[0075] Referring again to Figures 6 to 9, the top cover assembly 22 includes an upper cover 221 and a lower cover 222. The lower cover 222 has a lower powder inlet channel 2221 penetrating its upper and lower surfaces and an annular cavity surrounding the lower powder inlet channel 2221. The bottom of the annular cavity has a water outlet 2223 communicating with the brewing chamber 2111. The upper cover 221 has an upper powder inlet channel 2211 penetrating its upper and lower surfaces, with the upper end of the upper powder inlet channel 2211 forming a powder inlet 2212. The bottom surface of the upper cover 221 has a connecting portion 2214 extending downwards around the lower port of the upper powder inlet channel 2211. The upper cover 221 is snapped onto the lower cover 222. The lower port of the upper powder inlet channel 2211 is tightly connected to the upper port of the lower powder inlet channel 2221. The connecting part 2214 extends into the annular cavity, forming a water cavity 2222 between the connecting part 2214 and the bottom of the annular cavity. The water cavity 2222 is connected to the water supply component, which supplies water to the water cavity 2222. The water supplied to the water cavity 2222 is then sprayed into the brewing cavity 2111 through the water outlet 2223. The top cover assembly 22 in this application has an ingenious structural design. It can both add coffee powder to the brewing cavity 2111 and supply brewing water to the brewing cavity 2111 without interfering with each other.

[0076] Furthermore, as shown in Figure 7, a first sealing ring 23 is provided between the inner periphery of the connecting part 2214 and the inner wall of the annular cavity; a second sealing ring 24 is provided between the outer periphery of the connecting part 2214 and the outer wall of the annular cavity. By providing the first sealing ring 23 and the second sealing ring 24, the sealing performance of the water cavity 2222 can be ensured, preventing water leakage between the upper cover 221 and the lower cover 222.

[0077] In some embodiments, as shown in FIG8, the upper cover 221 is provided with a water inlet channel 2215 that avoids the powder inlet channel 2211 (the powder inlet channel and the water inlet channel 2215 do not intersect). One end of the water inlet channel 2215 communicates with the water chamber 2222, and the other end of the water inlet channel 2215 extends to the side of the upper cover 221 and protrudes outward to form a connector 2216, which forms a water inlet. By providing the connector 2216, it is convenient to connect with the water supply assembly when the brewing chamber unit 2 is installed on the body frame 1, so as to achieve smooth water supply.

[0078] Furthermore, the body frame 1 is provided with a water supply port of the water supply system (not shown in the figure). The water supply port is adapted to the connector 2216. When the brewing chamber unit 2 is installed on the body frame 1, the connector 2216 is plugged into the water supply port. In this way, the water supply system can be connected when the brewing chamber unit 2 is installed on the body frame 1, which improves the convenience of use.

[0079] Referring to Figures 6 and 9, the lower cover 222 has a positioning plug 2225 on its side, and the upper cover 221 has two connectors 2216. When the upper cover 221 is placed on the lower cover 222, the two connectors 2216 are located on opposite sides of the positioning plug 2225. The body frame 1 has a socket 12 and a hole; the socket 12 can be seen in Figures 19 and 22. When the brewing chamber unit 2 is installed on the body frame 1, the positioning plug 2225 is inserted into the socket 12, one connector 2216 (the connector 2216 located at the bottom in Figure 6) is inserted into the water supply port, and the other connector 2216 is inserted into the hole. By setting the positioning plug 2225, the accurate alignment of the connector 2216 with the water supply port and the hole can be ensured, achieving a blind insertion effect. The connector 2216, which is inserted into the water supply port, is used to connect the water chamber 2222 and the water supply system. The other connector 2216 is only used to connect to the body frame 1 when the brewing chamber unit 2 is installed on the body frame 1, so as to ensure the balance and stability of the brewing chamber unit 2 after installation. This connector 2216 can be a solid connector.

[0080] As shown in Figures 8 and 9, a portion of the bottom side of the lower cover 222 protrudes downward to form a plug 2224 that fits the opening of the brewing chamber 2111. The lower powder inlet channel 2221 extends to the bottom end of the plug 2224. The outer peripheral surface of the plug 2224 fits against the inner peripheral surface of the opening of the brewing chamber 2111. A third sealing ring 25 is fitted onto the plug 2224 to seal the opening and the plug 2224, preventing gas from leaking from the upper waterless space inside the brewing chamber 2111.

[0081] In some embodiments, as shown in Figures 10 to 12, the cavity assembly 21 includes a cavity 211, a filter 213, a cavity handle 214, a first latch 215, a second latch 216, a spring latch 217, and a reset component 219.

[0082] As shown in Figure 10, the cavity 211 has an approximately cylindrical structure, forming a brewing chamber 2111 that is open at the top and closed at the bottom. The bottom of the cavity 211 has a coffee liquid outlet 2113 that communicates with the brewing chamber 2111 (see Figure 21). The filter 213 is located near the bottom of the brewing chamber 2111. Coffee powder entering through the powder inlet 2212 falls onto the filter 213 and is supported by it.

[0083] As shown in Figures 11 and 12, the cavity handle 214 includes a first side 2141 and a second side 2142 opposite to each other, and a third side 2143 connecting the first side 2141 and the second side 2142, so that the cavity handle 214 forms an approximately U-shape and can be disposed on the circumferential outer side of the cavity 211 in a semi-enclosing manner. The third side 2143 of the cavity handle 214 is provided with a grip 2144 for easy holding by the user. A first buckle 215 is provided on the first side 2141, and a second buckle 216 is provided on the second side 2142. The first buckle 215 and the second buckle 216 have the same structure and are symmetrically arranged. Both the first buckle 215 and the second buckle 216 include a protrusion 2151 extending toward each other, and the protrusion 2151 is provided with at least one first protrusion 2152. Elastic elements 2154 are respectively provided between the first latch 215 and the second latch 216 and the cavity handle 214, so that the first latch 215 and the second latch 216 can move relative to the cavity handle 214 to retract inward or expand outward. The elastic element 2154 can be a spring. When the first latch 215 and the second latch 216 retract inward and retract inward, the hooks 2153 on the first latch 215 and the second latch 216 retract into the first side 2141 and the second side 2142 respectively, and the spring is compressed. When the first latch 215 and the second latch 216 expand outward and move away from each other, the hooks 2153 on the first latch 215 and the second latch 216 protrude outward from the first side 2141 and the second side 2142 respectively, and the spring is stretched to its natural state. A spring clip 217 is located on the third side 2143 and can move vertically. The spring clip 217 has multiple obliquely arranged guide holes 21711. First protrusions 2152 on the protrusion 2151 are correspondingly located within the guide holes 21711. When the spring clip 217 moves downwards, it causes the first latch 215 and the second latch 216 to retract inwards simultaneously, so that the hooks 2153 on both latches retract into the first side 2141 and the second side 2142 respectively. When the spring clip 217 moves upwards, it causes the first latch 215 and the second latch 216 to expand outwards simultaneously, so that the hooks 2153 on both latches extend outwards from the first side 2141 and the second side 2142 respectively. A reset component 219 is located at the bottom of the third side 2143 and acts on the spring clip 217 to apply a force to the spring clip 217 to move it upwards and reset it.

[0084] Preferably, as shown in Figures 10 to 12, the spring clip 217 includes a plate-shaped body 2171 and a pressing part 2172 protruding from the upper outer side of the plate-shaped body 2171. A guide hole 21711 is provided on the plate-shaped body 2171, and a reset component 219 is located below the plate-shaped body 2171 and acts on the plate-shaped body 2171. Specifically, the bottom of the plate-shaped body 2171 is provided with two rods 218, and the elastic component includes two springs, which are respectively sleeved on the two rods 218.

[0085] The plate-shaped body 2171 is provided with two sets of guide holes 21711 arranged vertically. Each set of guide holes 21711 includes two guide holes 21711 arranged in a figure-eight shape. The protruding part 2151 is provided with two first protrusions 2152, which are respectively located in the two guide holes 21711 of the two sets of guide holes 21711 that are close to it.

[0086] As shown in Figures 1 to 3, the frame 1 of the machine body is provided with slots 13 corresponding to the first buckle 215 and the second buckle 216 respectively. As shown in Figure 11, when the brewing chamber unit 2 is not installed on the machine body and no downward pressing is applied to the snap 217, the snap 217 is in an upward pop-up state under the action of the reset component 219, that is, the snap 217 is in the initial high position, and the snap 217 can be maintained in this state when no external force is applied to it. At the same time, the first buckle 215 and the second buckle 216 are respectively in a state of being far apart and extending outward under the action of the spring. At this time, the first protrusions 2152 on the two buckles are respectively located at the bottom end of the guide hole 21711 where they are located. When the brewing chamber unit 2 is installed into the machine body, the machine body frame 1 first squeezes the hooks 2153 on the first buckle 215 and the second buckle 216. The hooks 2153 drive the first buckle 215 and the second buckle 216 to retract inward at the same time and compress the spring. When the brewing chamber unit 2 is installed in place on the machine body (installed in the mounting position 11), the two buckles expand outward at the same time under the action of the spring, so that the hooks 2153 on them extend into the corresponding slots 13 respectively, thereby making the brewing chamber unit 2 stably limited on the machine body frame 1, thus completing the installation of the brewing chamber unit 2 on the machine body.

[0087] When the coffee brewing is complete and the brewing chamber unit 2 needs to be removed from the machine body, press down on the pressing part 2172 of the spring clip 217. When the spring clip 217 moves from the initial state to the low pressing state, the reset part 219 is compressed. At the same time, the first protrusions 2152 on the two clips are driven by the guide holes 21711 of the spring clip 217 to retract inward. When the first protrusions 2152 move to the top of the corresponding guide holes 21711, the hooks 2153 on the two clips are completely disengaged from the slots 13 on the machine frame 1, releasing the clips from the machine frame 1. The brewing chamber unit 2 can be removed from the machine body by pulling it outward with the handle 2144. The disassembly is convenient and quick.

[0088] In some embodiments, as shown in Figures 17 and 18, the sliding module 32 includes a powder door 321, a powder door bracket 322, a slanted slider 323, and a sealing gasket 324. The slanted slider 323 is disposed on the outside of the powder door bracket 322; the powder door 321 is installed inside the powder door bracket 322, and the powder door 321 has a second protrusion 3212 that passes through the powder door bracket 322 and extends into the slanted groove 3231 on the slanted slider 323; the bottom of the powder door 321 extends downward out of the powder door bracket 322; the sealing gasket 324 is sleeved on the bottom of the powder door 321. When the sliding module 32 moves laterally from the position where the powder inlet 2212 is open to a position above the powder inlet 2212, the powder door bracket 322 is limited and held in this position by the powder door frame 31. The drive mechanism 33 drives the inclined groove slider 323 to continue moving laterally. The inclined groove 3231 of the inclined groove slider 323 pushes the second protrusion 3212 of the powder door 321, causing the powder door 321 to move vertically toward the powder inlet 2212, so that the sealing gasket 324 presses against the flange 2213 and generates a preset amount of interference with the flange 2213. The sliding module 32 has a reasonable and compact structure, which can not only realize the lateral movement of the powder door 321, but also realize the vertical movement of the powder door 321, so that the powder door 321 can interfere with the flange 2213 on the top cover assembly 22 to achieve an interference fit and ensure sealing performance.

[0089] Further, as shown in Figure 17, the inclined groove slider 323 has a U-shaped structure and includes two opposing sidewalls extending laterally. One end of the two sidewalls is connected by an end wall, and the other end of the two sidewalls is open to form a lateral opening. Four inclined grooves 3231 are provided on the two sidewalls respectively. The powder door bracket 322 includes a base plate and four side plates provided on the base plate. The four side plates form a rectangular frame. The base plate has a through hole 3221, and the opposing front and rear side plates each have two elongated slots 3222 extending vertically to the upper and lower ends. The lateral opening of the inclined groove slider 323 moves towards the right side plate of the powder door bracket 322 and is partially enclosed on the outside of the powder door bracket 322. The powder door 321 includes an assembly part 3211 and a sealing part 3213 located at the bottom of the assembly part 3211. The assembly part 3211 is approximately rectangular and is adapted to be located within the space enclosed by the bottom plate and side plate of the powder door bracket 322, and is confined within the space by the powder door cover plate 326. Two second protrusions 3212 are respectively provided on the front and rear sides of the assembly part 3211. The second protrusions 3212 pass through the elongated slots 3222 on the powder door bracket 322 and extend into the inclined slots 3231. The sealing part 3213 is approximately columnar and extends out of the powder door bracket 322 through the through hole 3221. The bottom surface of the sealing part 3213 is flat and is used to seal the powder inlet 2212 on the top cover assembly 22. The sealing gasket 324 is annular and is fitted onto the outer periphery of the sealing part 3213. The upper end face of the sealing gasket 324 is provided with multiple hooks 3241, which are embedded in the assembly part 3211 to keep the sealing gasket 324 stably on the sealing part 3213.

[0090] Referring to Figure 17, blind holes 3223 are provided on opposite sides of the powder door bracket 322 parallel to its direction of movement (i.e., the front and rear sides of the powder door bracket 322 in Figure 17). A column 3224 is connected to the blind hole 3223 via a spring 3225. One end of the column 3224 protrudes from the blind hole 3223 and forms a spherical end, which is used to abut against the powder door frame 31 or the inclined slide block 323. This is used to achieve limiting of the powder door bracket 322 under certain resistance conditions between it and the powder door frame 31, and to limit the powder door bracket 322 and the inclined slide block 323 under certain resistance conditions.

[0091] As shown in Figure 17, a blind hole 3223 is provided on the front and rear sides of the powder door bracket 322 near its left and right ends, and a column 3224 is connected to the blind hole 3223 by a spring 3225. A first through hole 312 is provided on the front and rear sides of the powder door frame 31 near its left end, as shown in Figure 14. A second through hole 3232 is provided on the two opposite side walls of the inclined slide block 323 near its end wall. When the sliding module 32 moves from the position of opening the powder inlet 2212 to above the powder inlet 2212, the two columns 3224 on the left end of the powder door bracket 322 just enter the corresponding first through hole 312 of the powder door frame 31. When the powder inlet 2212 needs to be opened, the limiting position of the inner column 3224 of the first through hole 312 ensures that in the initial stage of opening the powder inlet 2212, the powder door bracket 322 remains stationary while the inclined slide block 323 moves relative to the powder door frame 31 first, thereby pulling the powder door 321 and the sealing gasket 324 upward to separate them from the powder inlet 2212. Then, the inclined slide block 323 and the powder door bracket 322 move laterally together to the position where the powder inlet 2212 is opened.

[0092] When the powder inlet 2212 is in the open state as shown in Figure 13, and it is necessary to close the powder inlet 2212, the two pillars 3224 at the right end of the powder gate bracket 322 just enter the second through hole 3232 corresponding to the inclined slide block 323, see Figure 14; when the drive mechanism 33 drives the inclined slide block 323 to start moving laterally in the direction of closing the powder inlet 2212, the powder gate bracket 322 can move together with the inclined slide block 323. When the sliding module 32 moves to the top of the powder inlet 2212, the left end of the powder gate bracket 322 abuts against the powder gate frame 31, while there is still a certain distance between the left end of the inclined slide block 323 and the powder gate frame 31. There is also a certain gap L between the powder gate bracket 322 and the inclined slide block 323, see Figure 14. The powder gate bracket 322 will not block the inclined slide block 323. When the drive mechanism 33 continues to drive the inclined slide block 323 to move laterally, the powder gate bracket 322 no longer moves laterally with the inclined slide block 323. When the inclined slide block 323 continues to move laterally, it simultaneously drives the powder gate 321 to move downward. When the inclined slide block 323 moves laterally by a stroke L, the powder gate bracket 322 forms a stop on the inclined slide block 323 (see Figure 16), and the inclined slide block 323 cannot continue to move. At the same time, the powder gate 321 moves downward by a preset distance so that the sealing gasket 324 and the flange 2213 produce a preset amount of interference, for example, the interference amount is 3mm, so as to achieve end face sealing of the powder inlet 2212, see Figures 15 and 16.

[0093] In some embodiments, as shown in Figures 13 to 16, the sliding module 32 further includes a rack plate 325, which is fixed to the inclined slide block 323. The rack plate 325 has a rack 3251 extending laterally on it. The driving mechanism 33 includes a motor 331, which is connected to a drive gear 332. The drive gear 332 meshes with the rack 3251. When the motor 331 starts, it drives the drive gear 332 to rotate, which in turn drives the rack 3251 and the rack plate 325 to move laterally. The rack plate 325 then drives the inclined slide block 323 to move synchronously. The above structure is simple and reasonable, and easy to implement.

[0094] As shown in Figures 14 and 16, the powder door frame 31 has an opening on one side perpendicular to the movement direction of the sliding module 32. The sliding module 32 can be installed into the powder door frame 31 through this opening. A baffle 313 can be installed on the opening side to seal it. A slide rail can be provided inside the powder door frame 31, and the extension direction of the slide rail is consistent with the movement direction of the sliding module 32. The sliding module 32 is mounted on the slide rail and moves along the slide rail.

[0095] As shown in Figure 21, the brewing chamber 2111 is located below the filter 213, forming a coffee liquid chamber 2112. A dispensing seat 212 is provided at the bottom of the chamber 211, with a dispensing channel 2121 inside. One end of the dispensing channel 2121 communicates with the coffee liquid chamber 2112, and the other end extends out of the dispensing seat 212 to form a dispensing connector 2122. A liquid guide seat 14 is provided on the machine frame 1, with an insertion interface 141 on the liquid guide seat 14. A liquid guide channel 142, with one end communicating with the insertion interface 141, is provided inside the liquid guide seat 14. The other end of the liquid guide channel 142 is connected to the spout assembly 17 located on the upper part of the machine via a pipe, so that the coffee liquid in the coffee liquid chamber 2112 can be dispensed through the spout assembly 17.

[0096] In this embodiment, the spout assembly 17 is located on the upper part of the machine body, eliminating the need to reserve space below the brewing chamber unit 2 for placing a coffee cup or coffee pot 4, thereby reducing the overall vertical size of the machine and allowing it to be made smaller. Coffee liquid exiting the brewing chamber unit 2 and entering the coffee liquid chamber 2112 can be delivered to the spout assembly 17 through a pipe under the pressure within the brewing chamber 2111, and provided to the user, without the need for a separate power unit to power the flow of coffee liquid.

[0097] In some embodiments, as shown in FIG24, the water supply assembly may include a water tank 151 and a boiler 152 (or heating element) connected to the water tank 151. The connector 2216 on the top cover 221 is connected to the boiler 152 via a silicone tube. Optionally, a tee 153 is provided on the silicone tube upstream of the boiler 152. One port of the tee 153 is connected to a one-way valve 156 (to prevent air from entering the water pump 154 ​​when the air pump 155 is working) and the water pump 154 ​​via a silicone tube. The other port of the tee 153 is connected to a one-way valve 156 (to prevent water from entering the air pump 155 when the water pump 154 ​​is working) and the air pump 155 via a silicone tube. This allows the air pump 155 to blow air into the brewing chamber 2111 to maintain a certain pressure required for accelerated dripping when the pressure at the end of the coffee dripping process in the sealed brewing chamber 2111 is insufficient.

[0098] The working principle of the accelerated drip coffee machine in this application embodiment is as follows:

[0099] In the initial state, the brewing chamber unit 2 is installed in the body frame 1. The hooks 2153 on the left and right buckles of the chamber component 21 are engaged in the corresponding slots 13 of the body frame 1. The top cover component 22 covers the upper port of the chamber component 21. At the same time, the two connectors 2216 of the top cover component 22 are connected to the soft rubber part of the connector female of the body frame 1. The powder inlet 2212 of the top cover component 22 is sealed and covered by the soft rubber part of the lower end face of the powder door 321 of the powder door component 3. After the user selects the type and number of coffee drinks on the machine's operating interface and confirms, motor 331 starts, driving the powder door assembly 3 to open the powder inlet 2212 on the top cover assembly 22. Then, the grinding mechanism starts grinding, and coffee powder falls into the brewing chamber 2111 through the powder inlet 2212. After grinding, motor 331 first drives the inclined slide block 323, powder door 321, and powder door support 322 in the powder door assembly 3 to move horizontally together to cover the powder inlet 2212. After the powder door 321 and powder door support 322 have moved horizontally into position, motor 331 continues to drive the rack plate 325 to move the inclined slide block 323 horizontally. The inclined slide block 323 drives the powder door 321 downwards a short distance through its inclined groove 3231, causing the sealing gasket 324 (made of soft rubber) on the powder door 321 to interfere with the flange 2213 (made of hard rubber) on the top cover 221 by a certain amount. This creates a good seal. Then, the water pump 154 ​​starts, sending water from the water tank 151 into the boiler 152. After being heated by the boiler 152, the water is sprayed into the brewing chamber 2111 through the top cover assembly 22. When the hot water at the bottom of the brewing chamber 2111 submerges the coffee powder on the filter screen 213, the brewing chamber 2111 is completely sealed. Due to the pressure of the air, the heat, and the water vapor, a certain pressure (low pressure) is automatically generated in the sealed brewing chamber 2111, thereby accelerating the drip filtration of coffee. After the water pump 154 ​​finishes pumping water and the coffee drip filtration is completed, manually press down the spring buckle 217 on the chamber handle 214 to disengage the buckle between the brewing chamber unit 2 and the machine frame 1. Then, use the handle 2144 on the chamber handle 214 to remove the brewing chamber unit 2 from the machine body. Turn it over to open the top cover assembly 22 of the brewing chamber unit 2 to empty and clean the coffee grounds. Then, put it back into the machine body for easy disassembly, cleaning, and installation.

[0100] The coffee machine of this application embodiment can not only greatly shorten the coffee dripping time, but also has a simple structure, low cost, and can effectively reduce the height of the coffee machine.

[0101] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
