[0002] Food processing machines include soy milk machines, juice machines, choppers, blenders and dough mixers, etc. which are small household electrical appliances providing different food processing functions and can meet different needs of people. The food processing machine generally comprises a cup body and a cup cover which is covered on the cup body. If the cup cover is not firmly covered on the cup body, it will affect the personal safety of the operator and result in poor use safety. For example, a Chinese patent with publication number CN105212788A discloses a food processor which comprises a cup body, a stirring assembly with a stirring shaft arranged in the cup body, and a cup cover which is covered on the opening of the cup body. It can be seen that the food processor can start the stirring assembly without checking whether the cup cover is properly covered, thus causing hidden dangers to the use safety of the product. SUMMARY

[0003] In view of the above technical problems existing in the prior art, the present application provides a food processing machine which makes the control device enter the power-on state only when the cup cover is properly covered, thus effectively improving the use safety of the product.

[0004] The embodiment of the present application provides a food processing machine which comprises a shell and a control device, and further comprises:

[0005] A cup assembly is arranged on the shell, and the cup assembly comprises a cup body and a cup cover which is arranged on the cup body. A through hole is arranged on the cup wall of the cup body.

[0006] An exhaust device comprises a sealing member and a driving assembly which is controlled by the control device to be opened and closed. An output shaft of the driving assembly extends into the cup body through the through hole. The sealing member is arranged on the extending end of the output shaft and is used to move under the driving of the driving assembly to open or close the through hole.

[0007] A protection device is arranged in the cup body. The protection device comprises a power-on switch which is connected with the control device. The power-on switch is used to be triggered when the cup cover is properly covered, so as to make the control device enter the power-on state. The above food processing machine makes the control device enter the power-on state only when the cup cover is properly covered, thus effectively improving the use safety of the product.

[0008] In some embodiments, the protection device further comprises a trigger for triggering the power-on switch, the trigger being sleeved on the output shaft, the trigger being used for locking the output shaft of the drive assembly when the cup cover is in the first position, the seal opening the through hole, and unlocking the output shaft of the drive assembly when the cup cover is in the second position, the output shaft being capable of driving the seal to switch between opening and closing the through hole; wherein the first position is a position in which the cup cover is not closed in place, and the second position is a position in which the cup cover is closed in place. In this way, through the action relationship between the trigger and the output shaft, when the cup cover is not closed in place, the double guarantee of avoiding the misstart of the drive assembly is realized through the untriggered power-on switch and the locking of the output shaft by the trigger, and the safety of the product is further improved.

[0009] In some embodiments, the trigger comprises a through hole for the output shaft to pass through, a clamping groove being formed in the hole wall of the through hole and being in communication with the through hole, and two annular bosses being formed on the output shaft, the clamping groove being located between the two annular bosses when the cup cover is in the first position to limit the axial displacement of the output shaft. The above-mentioned structure is stable in clamping and effectively avoids the misstart of the drive assembly.

[0010] In some embodiments, the trigger comprises a trigger body and a convex portion and a top rod portion arranged on opposite sides of the trigger body, a push block being arranged on the cup cover, the push block abutting against the convex portion when the cup cover is buckled on the cup body, and the top rod portion being pushed against the power-on switch to make the control device powered on. The above-mentioned trigger has a reasonable structure design, and the trigger as a whole is displaced towards the power-on switch through the triggering of the cup cover on the convex portion, so as to trigger the power-on switch through the top rod portion.

[0011] In some embodiments, the top rod portion is sleeved with a first elastic body, the first elastic body being used for exerting an action force on the trigger to make the trigger move away from the power-on switch. In this way, the trigger can move away from the power-on switch under the action of the elastic body when the cup cover is not closed in place, i.e. the cup cover does not exert an external force on the convex portion, so as to remain in a position in which the power-on switch is not triggered.

[0012] In some embodiments, the output shaft is sleeved with a second elastic body, the second elastic body being used for exerting an action force on the output shaft to make the output shaft stretch into the cup body, so as to open the through hole by the seal when the drive assembly is closed. The above-mentioned structure design is reasonable and has a compact layout.

[0013] In some embodiments, the inner part of the output shaft is formed with a water inlet channel, and the output shaft is provided with a water inlet opening and a water outlet opening in communication with the water inlet channel, the water outlet opening being located in the cup body when the sealing member opens the through hole, and the water inlet opening being located outside the cup body. The above structure is compact, and water is introduced into the cup body by using the structure of the output shaft, which is a clever design.

[0014] In some embodiments, the food processor further comprises a water inlet assembly, the cup wall of the cup body is provided with a water inlet hole, and the water inlet assembly comprises a piston member and a water inlet cavity in communication with the water inlet hole, the piston member penetrating the water inlet cavity and the water inlet hole and being used to move to open or block the water inlet hole. The water inlet mode of the above water inlet assembly is simple, and the structural layout is reasonable.

[0015] In some embodiments, the piston member comprises a piston rod and a third elastic body, the first end of the piston rod extends into the cup body from the water inlet hole, and the first end of the piston rod is formed with a blocking part for opening or blocking the water inlet hole, the third elastic body is sleeved on the second end of the piston rod and located outside the cup body, and is used to apply a force to the blocking part to block the water inlet hole. The third elastic body can block the water inlet hole when there is no water flow to the blocking part, thereby ensuring the sealing of the cup body.

[0016] In some embodiments, the cup body is provided with an exhaust joint in communication with the through hole, the exhaust joint is sleeved on the outside of the output shaft, and is used to exhaust the gas discharged through the through hole. The exhaust joint can guide the exhaust gas to be discharged from the exhaust joint.

[0017] Compared with the prior art, the beneficial effects of the embodiments of the present application are that: the present application triggers the power-on switch of the protection device when the cup cover is closed in place, so that the control device enters the power-on state only when the cup cover is closed in place, effectively improving the use safety of the product. When the cup cover is not closed in place, the control device cannot enter the power-on state, and the food processor cannot start processing food. When the cup cover is not closed in place, the trigger member can lock the output shaft of the driving assembly, so that the sealing member is in an open through hole state, i.e., the through hole cannot be sealed, so that the pressure in the cup body cannot be raised in a sealed state, thereby playing a safety protection role. In addition, the cup body is provided with a through hole and an exhaust device capable of opening or closing the through hole, so that the cup body can be switched between a sealed state and a non-sealed state, which is beneficial to exhausting the gas through the through hole in the non-sealed state to balance the air pressure in the cup body with the atmospheric pressure, achieving the purpose of quickly opening the cover and quickly exhausting the gas in the cup body.

DETAILED DESCRIPTION

[0034] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be described in detail below in conjunction with the drawings and specific embodiments.

[0035] The embodiment of the present application provides a food processor, as Figures 1 to 6 shown, the food processor comprises a housing 1 and a control device, and further comprises a cup assembly 2, an exhaust device 3 and a protection device 4. The cup assembly 2 is arranged on the housing 1, and the cup assembly 2 comprises a cup body 21 and a cup cover 22 arranged on the cup body 21, and a through hole 23 is arranged on the cup wall of the cup body 21. The exhaust device 3 comprises a sealing element 31 and a drive assembly 32 controlled to be opened and closed by the control device, and an output shaft 33 of the drive assembly 32 extends into the cup body 21 through the through hole 23, and the sealing element 31 is arranged at the extending end of the output shaft 33 and is used to move to open or close the through hole 23 under the driving of the drive assembly 32. The protection device 4 is arranged on the cup body 21, and the protection device 4 comprises a power-on switch 41 connected with the control device, and the power-on switch 41 is used to be triggered when the cup cover 22 is closed in place, so that the control device enters a power-on state.

[0036] As shown in Figures 1 to 6 , Figure 1 and Figure 2 , the cup cover 22 is in an unclosed state, and at this time, the through hole 23 is in an open state; Figure 3 and Figure 4 , the cup cover 22 is in a closed state, and at this time, the through hole 23 is in an open state; Figure 5 and Figure 6As shown in the middle of the cup cover 22 is in the closed position, at this time, the sealing member 31 is driven by the driving assembly 32 to close the through hole 23, that is, the through hole 23 is in a closed state.

[0037] Specifically, the food processor described above can further comprise a heating device and a temperature sensing probe 8 electrically connected to the control device, the heating device is used for heating the food material in the cup 21, the detection end of the temperature sensing probe 8 can be inserted into the cup 21, for real-time detection of the temperature of the food material in the cup 21, the control device receives the temperature and controls the operation of the heating device based on it.

[0038] Specifically, the through hole 23 can be located at the high position of the side wall of the cup 21, so as to avoid the food material in the cup 21 from leaking out of the through hole 23.

[0039] Specifically, the driving assembly 32 can be understood as being able to drive the sealing member 31 to move linearly, when the output shaft 33 of the driving assembly 32 moves into the cup 21, the sealing member 31 will be opened; when the output shaft 33 of the driving assembly 32 moves out of the cup 21 until the sealing member 31 abuts against the inner wall of the cup 21, the sealing member 31 closes the through hole 23.

[0040] Specifically, the power-on switch 41 can be understood as being electrically connected to the control device, which is used to control the on-off state of the control device. When the power-on switch 41 is not triggered, the control device is in an unpowered state, so that other modules electrically connected to the control device cannot work, thereby ensuring that when the cup cover 22 is not closed in place, the driving assembly 32, the heating device and other modules electrically connected to the control device cannot be started, avoiding the safety hazards caused by misoperation. After the power-on switch 41 is triggered, the control device enters a powered state, so that other modules electrically connected to the control device can work normally, that is, each module can be triggered to run by the user, or can automatically run after the control device is powered on, so that the driving assembly 32, the heating device and other modules electrically connected to the control device can only be started after the cup cover 22 is closed in place.

[0041] Specifically, the power-on switch 41 can be arranged below the cup cover 22, and the cup cover 22 will trigger the power-on switch 41 only after it is closed in place, otherwise, the power-on switch 41 is always in an untriggered state.

[0042] Specifically, after the sealing member 31 seals the through hole 23, the cup 21 can be understood as a closed container. After food materials are put into the cup 21, if water is added into the cup 21, the cup 21 will only have a water inlet port, which will cause the gas in the cup 21 to be continuously compressed. Under the action of the gas pressure in the cup 21, after a certain amount of water is added, the cup 21 will not be able to continue to add water. By setting the through hole 23 and the exhaust device 3, the gas in the cup 21 can be continuously discharged through the through hole 23 when water is added, so that the gas pressure in the cup 21 can be balanced with the atmospheric pressure, which is beneficial to the addition of water into the cup 21.

[0043] In addition, after the food materials are added into the cup 21, the heating device heats the food materials in the cup 21. At this time, by opening the through hole 23 through the sealing member 31, the gas pressure in the cup 21 will not continuously increase due to continuous heating, but the gas pressure in the cup 21 can be balanced with the atmospheric pressure at all times. It should be noted that if the gas pressure in the cup 21 continuously increases, the cup cover 22 cannot be opened under the action of the gas pressure in the cup 21. If the through hole is sealed at the initial room temperature state, the cup cover 22 can only be opened when the temperature in the cup 21 decreases to the initial temperature and the gas pressure in the cup 21 approaches the initial pressure from the high-pressure state, which results in that the user needs to wait for a long time for temperature decrease. The present application can open the through hole 23 through the sealing member 31 when the heating device is started, so that the gas pressure in the cup 21 can be balanced with the atmospheric pressure at all times. After the food materials are heated to a preset temperature, the driving assembly 32 can be started to seal the through hole 23 through the sealing member 31, so that the temperature in the cup 21 can be increased more quickly. At this time, as the temperature increases, the pressure also increases, and the cup cover 22 cannot be opened under the high-pressure state. When the temperature in the cup 21 decreases to the preset temperature, the cup cover 22 can be opened, and the cup cover 22 does not need to be opened until the temperature in the cup 21 decreases to the room temperature, which effectively shortens the waiting time for temperature decrease.

[0044] Exemplarily, in the prior art, the sealing member 31 is driven by the driving assembly 32 to close the through hole 23 at normal temperature 25℃, at this time, the cup body 21 is a sealed container, and the pressure in the cup body 21 is 1 atmosphere. After the heating device of the food processor heats the liquid in the cup body 21 to 100℃, the heating is stopped and the temperature is started to be reduced. When the temperature is reduced to 90℃, if the user needs to open the cover, since the temperature in the cup body 21 is much higher than the temperature before the sealing member 31 closes the through hole 23, at this time, the air pressure in the cup body 21 is greater than 1 atmosphere, and the user will have difficulty in opening the cover. If the cover is forcibly opened at this time, the user may be scalded by the hot air, and the pressure in the cup body 21 is basically the same as 1 atmosphere only when the temperature is reduced to the initial 25℃. Therefore, in order to shorten the waiting time for temperature reduction, the sealing member 31 is driven by the driving assembly 32 to open the through hole 23 at normal temperature 25℃, at this time, the air pressure in the cup body 21 can be balanced with the atmospheric pressure at all times. After the heating device of the food processor heats the liquid in the cup body 21 to 90℃, the 90℃ can be understood as the above-mentioned preset temperature, the sealing member 31 is closed to the through hole 23, and continues to be heated to 100℃. When the user needs to open the cover at this time, the air pressure in the cup body 21 is reduced to an openable state only by waiting for the temperature in the cup body 21 to be reduced from 100℃ to 90℃, which effectively reduces the waiting time for temperature reduction and improves the use safety of the product

[0045] The application triggers the power-on switch 41 of the protection device 4 when the cup cover 22 is closed in place, so that the control device enters the power-on state only when the cup cover 22 is closed in place, which effectively improves the use safety of the product. In addition, the cup body 21 is switched between the sealed state and the unsealed state through the through hole 23 and the exhaust device 3 capable of opening or closing the through hole 23, which is beneficial to balancing the air pressure in the cup body 21 with the atmospheric pressure in the unsealed state, and is also beneficial to quickly heating, stirring and other treatments of the food materials in the cup body 21 in the sealed state.

[0046] In some embodiments, as shown in Figures 1 to 6 and Figure 11 The protection device 4 further comprises a trigger 5 for triggering the power-on switch 41, the trigger 5 is sleeved on the output shaft 33, the trigger 5 is used for locking the output shaft 33 of the driving assembly 32 when the cup cover 22 is in the first position, so that the sealing member 31 opens the through hole 23, and the locking of the output shaft 33 of the driving assembly 32 is released when the cup cover 22 is in the second position, and the output shaft 33 can drive the sealing member 31 to switch between opening and closing the through hole 23; wherein the first position is a position where the cup cover 22 is not closed in place (as shown in Figure 1 and Figure 2 The second position is a position where the cup cover 22 is closed in place (as shown in Figures 3 to 6Thus, through the action relationship between the trigger 5 and the output shaft 33, when the cover is not closed in place, the double guarantee of avoiding the misstart of the driving assembly 32 can be realized through the untriggered power-on switch 41 and the locking of the output shaft 33 by the trigger 5, and the safety of the product is further improved.

[0047] Specifically, the trigger 5 can have a clamping portion for clamping with the output shaft 33. When the cup cover 22 is in the first position, the cup cover 22 will not act on the trigger 5 to move downward to trigger the power-on switch 41, and the clamping portion on the trigger 5 will be clamped with the output shaft 33, so that the output shaft 33 is locked.

[0048] In some embodiments, as shown in Figure 11 , Figure 12 The trigger 5 includes a through hole 51 for the output shaft 33 to pass through, and a clamping groove 52 is formed in the hole wall of the through hole 51 and communicates with the through hole 51. Two annular bosses 34 are formed on the output shaft 33, and the clamping groove 52 is located between the two annular bosses 34 when the cup cover 22 is in the first position, so as to limit the axial displacement of the output shaft 33. As shown in Figure 1 , Figure 2 The clamping groove 52 shown in the middle of Figure 1 , Figure 2 is in a state of being clamped between the two annular bosses 34. The above-mentioned clamping structure is stable, and effectively avoids the problem of misstart of the driving assembly 32.

[0049] Specifically, the through hole 51 can be configured as a circular hole, and the output shaft 33 passes through the through hole 51 and has a gap between the hole wall of the through hole 51. When the trigger 5 triggers the power-on switch 41, the output shaft 33 can move in the through hole 51 and drive the sealing element 31 to move linearly, so as to open or close the through hole 23.

[0050] Specifically, the clamping groove 52 can be configured as a rectangular groove formed by the hole wall of the through hole 51 extending outward. When the trigger 5 locks the output shaft 33, part of the output shaft 33 will be embedded in the clamping groove 52, and the clamping groove 52 is located between the two annular bosses 34, so that the output shaft 33 cannot be axially displaced again.

[0051] In some embodiments, as shown in Figure 2 , Figure 11 The trigger 5 includes a through hole 51 for the output shaft 33 to pass through, and a clamping groove 52 is formed in the hole wall of the through hole 51 and communicates with the through hole 51. Two annular bosses 34 are formed on the output shaft 33, and the clamping groove 52 is located between the two annular bosses 34 when the cup cover 22 is in the first position, so as to limit the axial displacement of the output shaft 33. As shown in Figure 13As shown, the trigger 5 includes a trigger body 53, and a convex portion 54 and a top rod portion 55 arranged on opposite sides of the trigger body 53. The cup cover 22 is provided with a push block 24, and the cup cover 22 is buckled on the cup body 21, and when the cup cover 22 is closed in place, the push block 24 pushes against the convex portion 54, and drives the top rod portion 55 to push against the power-on switch 41, so that the control device is powered on. The structure of the above-mentioned trigger 5 is reasonable, and through the triggering of the convex portion 54 by the cup cover 22, the trigger 5 can be displaced as a whole to the power-on switch 41, so as to trigger the power-on switch 41 through the top rod portion 55.

[0052] Specifically, the cup cover 22 can include a cover body and a cover, Figure 13 A structural schematic view of the cover of the cup cover 22, the cover is used to be sleeved on the outside of the cover body to press the cover body towards the cup body 21, and the push block 24 is formed on the side of the cover towards the cup body 21.

[0053] Specifically, the push block 24 can be a plurality of push blocks 24 arranged in a ring shape on one side of the cover.

[0054] In some embodiments, as shown in Figure 2 and Figure 4 The top rod portion 55 is sleeved with a first elastic body 42, which is used to apply an action force to the trigger 5 to move away from the power-on switch 41. In this way, in the case that the cup cover 22 is not closed in place, i.e. the cup cover 22 does not apply an external force to the convex portion 54, the trigger 5 can move away from the power-on switch 41 under the action of the first elastic body 42, so as to remain in a position not to trigger the power-on switch 41.

[0055] Specifically, the outer wall of the cup body 21 can be provided with a mounting bracket for mounting the protection device 4, the power-on switch 41 is located below the mounting bracket, the trigger 5 is mounted in the mounting bracket, the top rod portion 55 of the trigger 5 passes through a through slot in the mounting bracket to act on the power-on switch 41, and the lower end of the first elastic body 42 can abut against the inner wall of the mounting bracket, and the upper end can abut against the trigger 5.

[0056] In some embodiments, as shown in Figure 2 and Figure 12 The output shaft 33 is sleeved with a second elastic body 35, which is used to apply an action force to the output shaft 33 to stretch into the cup body 21, so that the sealing member 31 opens the through hole 23 when the driving assembly 32 is closed. In this way, in the case that the driving assembly 32 does not drive the output shaft 33 to move, the output shaft 33 can move towards the direction of the sealing member 31 under the action of the second elastic body 35, so that the sealing member 31 in the cup body 21 can remain in the state of opening the through hole 23. The above-mentioned structure is reasonable and compact.

[0057] Specifically, the driving assembly 32 can include a motor and a motor support, one end of the second elastic body 35 can abut against one of the two annular bosses 34 close to the motor, and the other end of the second elastic body 35 can abut against the outer wall of the motor support.

[0058] In some embodiments, as shown in Figure 2 and Figure 12 , the inner part of the output shaft 33 is formed with a water inlet channel, and the output shaft 33 is provided with a water inlet 36 and a water outlet 37 which communicate with the water inlet channel, the water outlet 37 is located in the cup body 21 when the sealing member 31 opens the through hole 23, and the water inlet 36 is located outside the cup body 21. The above structure is compact, and the water inlet into the cup body 21 is realized by using the structure of the output shaft 33, which is a clever design. Among them, as shown in Figure 3 and Figure 4 , the arrow direction shown in Figure 3 and Figure 4 is the water inlet direction of the water inlet channel.

[0059] Specifically, the output shaft 33 can include a plurality of shafts with the same axis and connected in sequence, and the shaft diameter of the shaft forming the water inlet channel can be larger than that of the other shafts, so as to facilitate increasing the flow area of the water inlet channel.

[0060] Specifically, the output shaft 33 can be configured as a partially hollow shaft, and the hollow part forms the water inlet channel, the water inlet 36 can be connected to a water tank, the water tank supplies water to the water inlet channel through the water inlet 36, and the water in the water inlet channel is discharged into the cup body 21 through the water outlet 37.

[0061] Specifically, the water outlet 37 can abut against the inner wall of the through hole 23 when the sealing member 31 closes the through hole 23, so as to realize the closing of the water outlet 37.

[0062] In some embodiments, as shown in Figures 7 to 10 , the food processor further includes a water inlet assembly 6, the cup wall of the cup body 21 is provided with a water inlet hole 25, the water inlet assembly 6 includes a piston member 61 and a water inlet cavity 62 which communicates with the water inlet hole 25, the piston member 61 penetrates the water inlet cavity 62 and the water inlet hole 25 and is used to open or block the water inlet hole 25. The water inlet mode of the above water inlet assembly 6 is simple, and the structural layout is reasonable.
