As shown in fig. 1 to 5, a beverage brewing device 200 according to an embodiment of the present application includes a cup 410, a cup valve, and a waterway switching mechanism 100. The cup 410 has an inner cavity 411, and a second water inlet 413 is disposed on the cup 410 and is communicated with the inner cavity 411. The cup valve 430 is provided at the second water inlet 413 of the cup 410. When the cup valve 430 is closed, the cup valve 430 is hermetically connected to the second water inlet 413 through a fourth sealing structure. Waterway switching mechanism 100 includes a main body 110, a water outlet valve 150, and a driving mechanism 190. The body 110 has a cavity 111. The main body 110 has a water outlet 115 and a driving opening 116, both communicating with the cavity 111 and the environment outside the main body 110. The second water inlet 413 communicates with the cavity 111 of the main body 110 such that the inner cavity 411 of the cup 410 communicates with the cavity 111 of the main body. The outlet valve 150 is provided at the outlet 115 of the main body 110. When the outlet valve 150 is closed, the outlet valve 150 is sealingly connected to the outlet 115 by the second sealing structure 202. The drive mechanism 190 has an output shaft 191. An output shaft 191 is provided at the drive opening 116. The output shaft 191 of the drive mechanism 190 is sealingly connected to the drive opening 116 by a third sealing structure 203. By the arrangement of the first sealing structure 201, the second sealing structure 202 and the third sealing structure 203, liquid in the cavity 111 is prevented from leaking out through the second water inlet 413, the water outlet 115 and the driving opening 116, and liquid in the inner cavity 411 of the cup 410 is also prevented from leaking out through the second water inlet 413. I.e. to avoid that the liquid in the cavity 111 and the liquid in the inner cavity 411 of the cup 410 do not flow according to a preset flow direction.

The beverage brewing device 200 can prevent the liquid in the cavity 111 from leaking through the water outlet 115 and the driving opening 116 by the arrangement of the second sealing structure 202 and the third sealing structure 203, and can prevent the liquid in the cavity 111 of the main body 110 from leaking through the second water inlet 413 by the arrangement of the fourth sealing structure, so that the liquid in the cavity 111 of the main body 110 is prevented from easily leaking due to the more openings.

The main body 110 of the waterway switching mechanism 100 is further provided with a water inlet 113 communicating with the cavity 111. Waterway switching mechanism 100 also includes a top piece 130 and a switch piece 170.

Wherein the top 130 is movably disposed within the top aperture 119. The top 130 moves to switch between the jack-up position and the drop-back position. When the top member 130 is moved from the falling position to the jacking position, the top member 130 is moved in a direction away from the cavity 111. When the top member 130 moves from the jack-up position to the drop-back position, the top member 130 moves in a direction approaching the cavity 111.

The switching member 170 is movably disposed in the cavity 111 of the main body 110. The switching member 170 is switchable between a first position, a second position and a third position. When the switch 170 is switched to the first position, the outlet valve 150 remains automatically opened, and the top member 130 can be forced to remain in the retracted position, see fig. 6. When the switch 170 is switched to the second position, the switch 170 urges the outlet valve 150 to remain closed and the switch 170 urges the top member 130 to remain in the raised position, see fig. 7. When the switch 170 is switched to the third position, the outlet valve 150 remains automatically open, and the switch 170 urges the top member 130 to remain in the raised position, see fig. 8. The driving mechanism 190 is used to drive the switching member 170 to move. In the cup assembly, the cup valve remains automatically closed without the action of external force. The top 130 abuts the cup valve 430 such that the cup valve 430 moves in a direction toward the cup cavity of the cup to open the cup valve 430.

Specifically, referring to fig. 6, when the switch 170 is in the first position, the outlet valve 150 remains automatically open, and the top 130 may be forced to remain in the unseated position, i.e., the cup valve 430 abutting the top 130 may remain automatically closed. Therefore, the water entering from the water inlet 113 can directly flow out from the water outlet 115, and the water diversion mode of the water inlet 113 entering the water outlet 115 can be realized.

Referring to fig. 7, when the switching member 170 is in the second position, the switching member 170 drives the water outlet valve 150 to be closed, so that the water outlet 115 is blocked, and water in the cavity 111 cannot flow out from the water outlet 115. At the same time, the switch 170 forces the top piece 130 to remain in the jack-up position, i.e., the cup valve abutting the top piece 130 is opened. Therefore, the water entering from the water inlet 113 can flow out from the second water inlet 413, so that the water guiding mode of the water inlet 113 for the water entering from the second water inlet 413 can be realized, i.e. the water storage operation of the cup 410 is realized.

Referring to fig. 8, when the switch 170 is in the third position, the outlet valve 150 remains automatically open. At the same time, the switch 170 forces the top piece 130 to remain in the jack-up position, i.e., the cup valve abutting the top piece 130 is opened. In addition, in use, the second water inlet and outlet is located at a position near the bottom wall of the bottom side or the side wall of the cup body, so that the liquid in the cup body 410 can flow out from the second water inlet and outlet to the cavity 111 under the action of gravity. Therefore, the fluid entering the cavity 111 from the second water inlet 413 can flow out from the water outlet 115, so that the flow guiding mode of water entering from the second water inlet 413 and water exiting from the water outlet 115 can be realized.

In this embodiment, the outlet valve 150 is sealingly connected to the sidewall of the outlet 115 by a second sealing structure 202. Specifically, the outlet valve 150 has a second drop preventing portion 151, and the second sealing structure 202 includes a second sealing sleeve 2021 covering the second drop preventing portion 151. It will be appreciated that the second seal housing 2021 serves to effect a seal of the water valve 150 to the inner sidewall of the water outlet 115. It will be appreciated that in order to achieve the fit of the second seal sleeve 2021 to the inner side wall of the outlet, the second seal sleeve 2021 has a second sealing abutment 2022 which mates with the inner side wall of the outlet 115. And the second sealing joint surface 2022 is annular, so as to realize the sealing of the water outlet 115.

The second seal sleeve 2021 covers the second anti-disengagement portion 151, which means that the second seal sleeve 2021 completely covers the exposed surface of the second anti-disengagement portion 151. And the second sealing sleeve 2021 has a second sealing abutment surface 2022 matching with the inner side wall of the water outlet 115, so that a portion of the second sealing sleeve 2021 between the second sealing abutment surfaces 2022 is continuous, so that the second sealing sleeve 2021 can completely seal the water outlet 115. Therefore, even if there is a gap between the second seal housing 2021 and the water outlet valve 150, the liquid in the cavity 111 of the main body 110 can be prevented from leaking out from between the water outlet valve 150 and the second seal housing 2021.

In this embodiment, the second seal engaging surface 2022 is a tapered surface. Therefore, even if there is an error in the dimensions of the second seal bonding surface 2022 and the water outlet 115 during the preparation, the second anti-drop portion 151 of the water outlet valve 150 is limited to the depth inside the water outlet 115, and the relative position of the second seal bonding surface 2022 and the inner sidewall of the water outlet 115 can be adjusted, so that the second seal bonding surface 2022 is in sealing bonding with the inner sidewall of the water outlet 115.

It will be appreciated that in other possible embodiments, the second sealing abutment surface is not limited to a conical surface, but may be a folded surface or a curved surface, so as to increase the abutment area of the second sealing abutment surface with the inner sidewall of the water outlet, and further increase the sealing effect of the second sealing sleeve with the inner sidewall of the water outlet.

Of course, it will be appreciated that in other possible embodiments, the second sealing structure is not limited to sealing engagement with the inner side wall of the outlet, but may also be sealing engagement with other locations of the main body, and sealing of the outlet may be achieved when the outlet valve is sealed with the outlet to prevent fluid within the cavity of the main body from escaping through the outlet.

In this embodiment, the output shaft 191 of the driving mechanism 190 and the inner side wall of the driving opening 116 are hermetically connected by the third sealing structure 203. Specifically, the third sealing structure 203 includes a third sealing ring 2031 disposed between the output shaft 191 and the inner sidewall of the drive opening 116. Specifically, in this embodiment, the third sealing ring 2031 is sleeved on the output shaft 191. Therefore, before the output shaft 191 is placed in the driving opening 116, the third sealing ring 2031 can be sleeved on the output shaft 191, and the operation is simple.

More specifically, in the present embodiment, the output shaft 191 is completely sleeved on the shield 193, and the third seal 2031 is sleeved on the shield 193. An annular groove 1931 is provided on the outer side wall of the shroud 193, and a third seal 2031 is received in the annular groove 1931. Thus, the third seal ring 2031 is prevented from sliding in the axial direction of the output shaft 191.

In this embodiment, the third sealing structure 203 includes two third sealing rings 2031, so that there is a better sealing effect between the output shaft 191 and the inner sidewall of the driving opening 116. It will be appreciated that in other possible embodiments, the third sealing structure 203 is not limited to comprising two third sealing rings 2031, but may comprise one or more than two sealing rings as desired.

Of course, in other possible embodiments, the third sealing ring may also be embedded on the inner side wall of the drive opening. Optionally, a groove or the like may be provided on the inner side wall of the driving opening, so as to avoid the third sealing ring from moving along the axial direction of the output shaft. And when the third sealing structure comprises at least two third sealing rings, the third sealing rings are not limited to be sleeved on the output shaft only, and are not limited to be embedded on the inner side wall of the driving opening only. Part of the third sealing ring is sleeved on the output shaft, and part of the third sealing ring is embedded on the inner side wall of the driving opening.

Specifically, in the present embodiment, the portion of the switching member 170 that is in sealing engagement with the side wall of the driving opening 116 of the main body 110 is stepped, so as to increase the engagement area of the switching member 170 with the side wall of the driving opening 116 of the main body 110, and improve the sealing effect of the switching member 170 with the side wall of the driving opening 116 of the main body 110. The side wall of the driving opening 116 is simultaneously fitted with the switching member 170 and the shield 193, thereby better increasing the sealing effect of the driving opening 116.

Of course, it will be appreciated that in other possible embodiments, the third sealing structure is not limited to sealing engagement with the inner sidewall of the drive opening, but may also be sealing engagement with other locations of the main body, so as to seal the drive opening to prevent fluid from flowing out of the interior cavity of the cup body through the drive opening.

In this embodiment, the cup valve 430 is hermetically connected to the sidewall of the second water inlet 413 through a fourth sealing structure. Specifically, the cup valve 430 has a first anti-disengaging portion 431, and the fourth sealing structure includes a first sealing sleeve 450 coated on the first anti-disengaging portion 431. The first sealing sleeve 450 has a first sealing surface 451 that mates with the inner sidewall of the second inlet 413.

It should be noted that, the first sealing sleeve 450 covers the first anti-falling portion 431, which means that the first sealing sleeve 450 completely covers the exposed surface of the anti-falling portion. And the first sealing sleeve 450 is provided with a first sealing joint surface 451 matched with the inner side wall of the second water inlet 413, and the area of the first sealing sleeve 450 surrounded by the first sealing joint surface 451 is continuous, so that the first sealing sleeve 450 and the inner side wall of the second water inlet 413 are tightly jointed in the circumferential direction, and the second water inlet 413 can be completely sealed. Therefore, even if there is a gap between the first seal cover 450 and the cup valve 430, the liquid in the cup 410 can be prevented from leaking out from between the cup valve 430 and the first seal cover 450. Thereby avoiding accidental injury to people ready to receive water or pass by the liquid in the cup 410. In addition, when the water collecting box is arranged at the lower side of the cup body 410, the phenomenon that the water collecting box is easy to overflow due to the leakage of the liquid in the cup body 410 is avoided. Furthermore, when the water collecting box is not arranged at the lower side of the cup body 410, the phenomenon that the placing surface for placing the beverage brewing device 200 is soaked for a long time due to the leakage of the liquid in the cup body 410 can be avoided, and further, the structure of the beverage brewing device 200 close to the placing surface can be prevented from being wetted.

Specifically, in the present embodiment, the first anti-falling portion 431 is located in the inner cavity 411 of the cup 410. The edge between the first anti-falling portion 431 and the first sealing sleeve 450 and facing the bonding portion is located at a position where the first anti-falling portion 431 is far away from the inner cavity 411 of the cup 410. Accordingly, when the cup valve 430 is attached to the water inlet/outlet, the first seal contact surface 451 can be brought into sealing contact with the inner wall of the second water inlet/outlet 413 by moving the first escape prevention portion 431 in a direction toward the second water inlet/outlet 413. That is, when the cup valve 430 is closed, that is, when the second water inlet/outlet 413 is blocked, the first sealing surface 451 is sealed to the inner sidewall of the second water inlet/outlet 413, so that the edge between the first anti-release portion 431 and the first seal cover 450 is sealed from the inner cavity 411 of the cup 410, and thus, the liquid in the cup 410 can be prevented from flowing into the gap between the first anti-release portion 431 and the first seal cover 450, and further, the leakage of the liquid can be prevented better.

Generally, the structure for driving the cup valve 430 to move toward or away from the interior cavity 411 of the cup 410 is located outside the cup 410. The first anti-falling portion 431 is located in the inner cavity 411 of the cup 410, so that the first sealing sleeve 450 is also located in the inner cavity 411 of the cup 410, and when the cup valve 430 is driven to move, the acting point acting on the cup valve 430 can avoid the first sealing sleeve 450, so that damage to the first sealing sleeve 450 is avoided, and the service life of the first sealing sleeve 450 is effectively ensured.

Of course, in another possible embodiment, the first anti-disengaging portion may also be located at a position corresponding to the inner cavity of the cup body, that is, the first anti-disengaging portion is located outside, and may also move through the first anti-disengaging portion in a direction close to the second water inlet and outlet, so that the first sealing joint surface is in sealing joint with the inner side wall of the second water inlet and outlet, and further the first sealing sleeve may completely seal the second water inlet and outlet. At this time, although the edge attached between the first anti-drop part and the first sealing sleeve is communicated with the inner cavity of the cup body, and is communicated with the inner cavity of the inner body. Even if the liquid in the inner cavity of the cup body flows into the gap between the first anti-falling part and the first sealing sleeve, the liquid can only exist in the gap between the first anti-falling part and the first sealing sleeve, so that the outflow of the liquid in the inner cavity of the cup body is avoided.

It can be appreciated that the structures of the inner sidewalls of the first seal joint surface 451 and the second water inlet 413 can be set with reference to the structures of the second seal joint surface 2022 and the second water inlet 413, which will not be described herein.

Of course, the first seal abutment surface 451 and the second seal abutment surface 2022 may be the same or different in size and shape.

Of course, it will be appreciated that in other possible embodiments, the fourth sealing structure is not limited to sealing and fitting with the side wall of the second water inlet and outlet, but may also seal and fitting with other positions of the cup body, and may seal the second water inlet and outlet to prevent fluid in the inner cavity of the cup body from flowing out through the second water inlet and outlet when the cup body valve is sealed with the second water inlet and outlet.

In this embodiment, the waterway switching mechanism 100 is detachably connected to the cup 410. The main body 110 has a first water inlet/outlet 117 communicating with the cavity 111. The first water inlet and outlet 117 and the second water inlet and outlet 413 are in sealing butt joint through the first sealing structure. Waterway switching mechanism 100 is removably coupled to cup 410 to facilitate cleaning of cup 410 and/or waterway switching mechanism 100.

Specifically, in the present embodiment, the main body 110 is provided with a first docking ring 118 surrounding the first water inlet 117 and extending in a direction away from the cavity 111, and the first sealing structure 201 includes a sealing hanger 2011 riding on the first docking ring 118 along the extending direction of the first docking ring 118. Thereby preventing the first sealing structure 201 from moving along the extending direction of the first docking ring 118, and further avoiding the influence of the movement of the sealing hanger 2011 on the sealing effect of docking the first water inlet 117 with the cup 410. In addition, when the sealing pendant 2011 is mounted on the first docking ring 118, the sealing pendant 2011 is aligned with the first docking ring 118, and the sealing pendant 2011 is pushed along the extending direction of the first docking ring 118, or the sealing pendant 2011 moves under the external force such as self power, so that the sealing pendant 2011 rides on the first docking ring 118, and the operation is simple and quick.

Alternatively, in another possible embodiment, if the inner sidewall of the first water inlet and the second water inlet are directly abutted with each other, the sealing hanger may be ridden on the inner sidewall of the first water inlet and the second water inlet. Specifically, referring to fig. 13, in another embodiment, the riding direction of the sealing hanger 2013 is perpendicular to the direction of the inner sidewall of the first water inlet 117. Thus, the sliding of the seal hanger 2013 can be prevented, and the sealing butt joint of the first water inlet and outlet 117 and the second water inlet and outlet can be ensured.

In this embodiment, the bottom wall of the cup 410 is provided with a second abutment ring 415 extending outwardly. The second docking ring 415 is inserted into the first docking ring 118. It can be appreciated that the second docking ring 415 is disposed around the second water inlet 413, so that the first docking ring 118 and the second docking ring 415 are in sealing docking with each other by the first sealing structure 201, so as to realize sealing docking between the first water inlet 117 and the second water inlet 413.

Of course, in other possible embodiments, the first docking ring 118 and the second docking ring 415 may also be sized such that the first docking ring 118 is inserted within the second docking ring 415.

It will be appreciated that in other possible embodiments, the first docking collar may be inserted into the second water inlet if the depth of the second water inlet is sufficient. Therefore, the inner side wall of the second water inlet and outlet is in sealing connection with the first butt joint ring through the first sealing structure, so that the first water inlet and outlet are in sealing connection with the second water inlet and outlet. Of course, it is understood that the first docking collar is located on a side of the first anti-slip portion that is remote from the interior cavity of the cup.

In this embodiment, the body 110 includes a first half 01 and a second half 02. The first half 01 and the second half 02 are sealed and butted by a fifth sealing structure to enclose a cavity 111. Thus, the liquid in the cavity 111 is prevented from flowing out from the position where the first half 01 and the second half 02 are butted.

Of course, it will be appreciated that in other possible embodiments, the body is not limited to being composed of two halves, but may be composed of more than two elements. Alternatively, the body may be integrally formed. Specifically, the mode of integral molding can be directly integrated into a whole, or the half-body primary body can be prepared first, and then the half-body primary body is butted and continuously molded, so that the butted half-body primary body is welded into a whole.

Alternatively, the first sealing boot 450 is a rubber sealing boot. The rubber material has good sealing performance, is easy to form and has low cost. Also, alternatively, the second seal sleeve 2021 is a rubber seal sleeve.

It can be appreciated that in other possible embodiments, the first sealing surface is not limited to a conical surface, but may be a folded surface or a curved surface, so as to increase the bonding area between the first sealing surface and the inner sidewall of the second water inlet and outlet, and further increase the sealing effect between the first sealing sleeve and the inner sidewall of the second water inlet and outlet.

Of course, it will be appreciated that in a possible embodiment, the first sealing surface may be any regular or irregular shape, so that the cup valve can move in a direction approaching or separating from the inner cavity of the cup, so that the cup valve can be switched between open and closed, and when the cup valve is closed, the first sealing sleeve can be in sealing fit with the inner side wall of the second water inlet to realize sealing and blocking of the second water inlet.

Specifically, in the present embodiment, referring to fig. 7, 9 and 10, a side of the switching member 170 near the water outlet 115 is provided with a first protrusion 171. Referring to fig. 7, when the switching member 170 is located at the second position, the first protrusion 171 abuts against the water outlet valve 150, so that the water outlet valve 150 is kept closed. Specifically, in this embodiment, the side surface m of the first protrusion 171 is an inclined surface, and the side surface of the first protrusion 171 may be abutted against the water outlet valve 150 at first, so that the pressure applied by the first protrusion 171 on the water outlet valve 150 is gradually increased, even if the closing process of the water outlet valve 150 is a gradually closing process, the stress applied to the water outlet valve 150 is smaller when the water outlet valve 150 is closed, and further, the phenomenon that the stress applied to the water outlet valve 150 is larger is avoided, and further, the damage to the water outlet valve 150 due to the larger stress is avoided, and the damage to the first protrusion 171 due to the larger stress is also avoided, thereby increasing the service lives of the switching member 170 and the water outlet valve 150.

In the present embodiment, referring to fig. 7, 9 and 10, a side of the switching member 170 adjacent to the second water inlet 413 is provided with a second protrusion 173. When the switching member 170 is located at the second position, the second protrusion 173 abuts against the top member 130, so that the top member 130 is maintained at the jack-up position. Specifically, in the present embodiment, the side surface n of the second protrusion 173 is an inclined surface, and the side surface of the second protrusion 173 may be abutted against the top member 130 first, so that the pressure exerted on the top member 130 by the second protrusion 173 is gradually increased, that is, the top member 130 is gradually jacked up, so that the stress applied to the top member 130 when jacked up is smaller, and further, the phenomenon that the stress applied to the top member 130 is larger can be avoided, further, the damage of the top member 130 due to the larger stress is avoided, the damage of the second protrusion 173 due to the larger stress is avoided, and the service lives of the switching member 170 and the top member 130 are prolonged.

Further, referring to fig. 11 and 12, in the present embodiment, the top member 130 has the side abutment surface 133 matched with the inclined surface n of the second protrusion 173, so that when the top member 130 abuts against the side surface n of the second protrusion 173, the side abutment surface 133 of the top member 130 abuts against the side surface n of the second protrusion 173, so that the top member 130 is in surface contact with the second protrusion 173, thereby reducing the pressure of the top member 130 and the second protrusion 173 in the process, and also avoiding the occurrence of the stress concentration phenomenon.

In this embodiment, when the top member 130 is located at the falling position, the side abutment surface 133 of the top member 130 abuts against the bottom of the side surface n of the second protrusion, as shown in fig. 12. When the top piece 130 is located at the falling position, the top piece 130 is in surface contact with the second protrusion 173, so that on one hand, the top piece 130 can be better limited to enable the top piece 130 to be more stably kept at the falling position, and on the other hand, the pressure between the top piece 130 and the switching piece 170 can be smaller.

In this embodiment, the switching member 170 is rotatably disposed in the cavity 111 of the main body 110; the switching member 170 may be sequentially rotated from the first position to the second position and the third position in the same rotation direction, and may be switched between two adjacent positions. Accordingly, the switching member 170 may also be sequentially rotated from the third position to the second position and the first position in the opposite rotation directions.

In this embodiment, the first water inlet 117 is provided separately from the top piece penetration 119. It will be appreciated that in other possible embodiments, the first water inlet and outlet and the top piece aperture may also refer to the same opening provided in the main body. Namely the opening serves as both the first water inlet and outlet and the top piece perforation. In other words, the top piece is arranged in the opening in a penetrating way, and a space is arranged between the top piece and the side wall of the opening so that liquid can flow into or flow out of the drink generating container through the space between the top piece and the side wall of the opening.

As shown in fig. 14, another embodiment of the present application provides a beverage brewing device 500, which differs from the beverage brewing device 200 in that the first sealing structure 201 and the second sealing structure 202 are different.

Likewise, the first sealing structure 201 also includes two first sealing rings 2013 to increase the sealing effect between the first water inlet and the second water inlet 413. Of course, in other possible embodiments, the first sealing structure is not limited to two first sealing rings, and may include one or more than two first sealing rings as desired.

Specifically, in this embodiment, the first seal ring 2013 is sleeved on the second docking ring 415. Of course, in other possible embodiments, the first sealing ring may also be embedded on the inner side wall of the first docking ring.

Of course, in another possible embodiment, if the first docking ring is inserted into the second docking ring, the first sealing ring may be sleeved on the first docking ring, or may be embedded on the inner side wall of the second docking ring.

In this embodiment, the second sealing structure 202 includes a second sealing ring 2023 disposed between the inner sidewall of the water outlet 115 and the water outlet valve 150. Likewise, the second sealing structure 202 also includes two second sealing rings 2023 to increase the sealing effect between the inner sidewall of the water outlet 115 and the water outlet valve 150.

Specifically, in the present embodiment, the second seal ring 2023 is sleeved on the second anti-falling portion 151. It will be appreciated that in other possible embodiments, the second sealing ring may also be embedded on the inner side wall of the outlet 115.
