Description

Technical Field

[0001] The utility model belongs to the technical field of food processing devices, and in particular relates to a food processing machine with reliable structure. Background Art

[0002] The applicant's prior Chinese patent application, application number 201920675006.7, discloses a food processing machine comprising a grinding chamber, wherein the grinding chamber is provided with an outlet for cleaning the chamber wall, and the wall of the grinding chamber is also provided with an exhaust passage communicating with the outside; a three-way pipe having a first pipe, a second pipe, and a third pipe, the first pipe being connected to the outlet; an air supply device and a water supply device, respectively connected to the second pipe and the third pipe. The water supply device supplies water into the grinding chamber to flush the chamber wall, and the air supply device supplies air into the grinding chamber to flush the chamber wall, thereby cleaning the inner surface of the grinding chamber. Compared with a single water cleaning method, the grinding chamber has a better cleaning effect. After cleaning, the air supply device supplies air into the grinding chamber to increase the air flow rate in the grinding chamber, so that residual water adhering to the inner surface of the grinding chamber evaporates quickly and is discharged to the outside through the exhaust passage. This can improve the drying effect of the grinding chamber, prevent the generation of odor and the breeding of bacteria in the grinding chamber, and improve the performance of the food processing machine.

[0003] However, in the prior art, the grinding chamber is fixed on the main machine, and the user cannot remove the cup body to manually pour out the pulp or manually clean it, which is inflexible to use.

[0004] The applicant has also developed a food processor with a detachable cup. The cup can be removed from the main unit, which is internally fixed with a water pump, air pump, and tee. The cup is also fixed with a plug connector that communicates with the inner cavity of the cup. Once the cup is in place, the plug connector connects to the output connector of the tee. This solution allows users to manually pour thick slurry or manually remove the cup to pour out the cleaning water, making it more flexible. However, for this type of food processor, residual water may remain at the plug connector of the cup, making it very easy to leak when the user removes the cup. Water at the plug connector can easily drip onto the main unit, causing cleaning problems, or even flow into the main unit's interior, causing damage to the metal structure. Utility Model Content

[0005] The utility model provides a food processing machine with a reliable structure. The cup assembly is detachable and the main machine supplies water to the cup assembly through a coupling joint. On the basis of realizing flexible use of the cup assembly, the problem of water leakage at the coupling joint position after the cup assembly is removed from the main machine is solved.

[0006] The technical solution adopted by this utility model is:

[0007] The utility model provides a food processing machine with reliable structure, comprising a main unit and a cup assembly, wherein the cup assembly can be detachably mounted on the main unit, the main unit is provided with a control device, a water pump and an air pump controlled by the control device, and an output joint, the output ends of the water pump and the air pump are both connected to the output joint, the cup assembly comprises a crushing cup provided with a supply port, a supply pipe, and a coupling joint, the coupling joint is plugged and matched with the output joint to achieve communication, the supply pipe is connected between the supply port and the coupling joint, a one-way valve is provided in the supply pipe, the one-way valve separates the supply pipe into a front water channel and a rear water channel, the water pump outputs water through the output joint so that the water flows through the front water channel and the rear water channel in sequence and enters the crushing cup, and the air pump is used to blow the water in the front water channel into the rear water channel before the cup assembly is separated from the main unit.

[0008] The utility model provides a food processing machine with reliable structure. By detachably mounting the cup assembly on the main machine, the user can remove the cup assembly and pour out the slurry after preparing thick slurry, so as to prevent the thick slurry from clogging the drain valve. The utility model is flexible to use. By arranging a water pump and an air pump, the output ends of the water pump and the air pump are both connected to the output joint. The cup assembly includes a crushing cup with a supply port, a supply pipe, and a coupling joint. The coupling joint is plugged into and matched with the output joint to achieve communication. The supply pipe is connected between the supply port and the coupling joint. Therefore, the water pump and the air pump share a supply pipe to supply corresponding media to the crushing cup. The utility model has a compact structure. A one-way valve is arranged in the supply pipe. The one-way valve connects the supply port to the crushing cup. The pipe is divided into a front water channel and a rear water channel. The water pump outputs water through the output connector so that the water flows through the front water channel and the rear water channel in sequence and enters the grinding cup. The one-way valve can realize one-way flow of water and prevent water from flowing back to the water pump or the air pump. At the same time, the air pump is used to blow the water in the front water channel into the rear water channel before the cup assembly is separated from the main unit. The one-way valve isolates the front water channel and the rear water channel. Therefore, the one-way valve can block water backflow and dripping after the water is blown to the rear water channel, and will not affect the plugging and unplugging of the cup assembly. While preventing the user from dripping when removing the cup assembly, the cup assembly can be easily installed, and the one-way valve will not be loosened due to frequent friction at the plugging and unplugging position, and the anti-leakage effect is reliable.

[0009] In a preferred embodiment, the food processor further includes a movable part that can move relative to the cup assembly to have a working state and a non-working state, and a detection device that can detect the state of the movable part. The detection device is connected to the control device, and the control device is used to control the operation of the air pump after the detection device detects that the movable part is in a non-working state.

[0010] By incorporating active components and a detection device, the air pump's status is linked to the detection device's. This ensures that the air pump operates effectively before the user separates the cup assembly from the main unit, effectively blowing water from the front water channel to the rear water channel. This effectively prevents water temporarily stored in the front water channel from dripping. Furthermore, precise and reliable air pump control prevents misoperation and ensures proper system operation. By linking the control device, detection device, and air pump, users can confidently remove the cup assembly after machine processing, enhancing the user experience.

[0011] More preferably, the main unit includes a casing and a cover arranged above the casing, the cover and the casing form an installation cavity for enclosing the cup assembly, the movable part is the cover, the cover and the casing form an installation cavity for enclosing the cup assembly in a working state, and the cover is open relative to the casing in a non-working state.

[0012] More preferably, the cover is hinged to the casing, the host further comprises a button for controlling the opening and closing of the cover, a damping structure is provided between the casing and the cover so that the cover is fully opened relative to the cover after a preset time after the button is triggered, and the control device is used to control the air pump to operate within the preset time.

[0013] By adopting the machine cover and the machine casing to form an installation cavity surrounding the cup assembly, the cup assembly is fully wrapped and the working noise of the cup assembly is reduced. By arranging a damping structure between the machine casing and the machine cover, the opening of the machine cover can be buffered, thereby improving the structural reliability. The machine cover is fully opened relative to the machine cover after a preset period of time after the button is triggered, i.e., a time difference in opening the cover is formed. Under the control of the control device, the air pump can use the time difference in opening the cover to complete the blowing action, so that the water in the front water channel is quickly blown into the rear water channel to form scattered water droplets or form water vapor to be discharged, both of which can prevent dripping during the separation of the cup assembly from the main unit. For the user, it is only necessary to follow the normal operation, press the button to open the cover, and then wait for the machine cover to be fully opened to take out the cup assembly normally for pouring slurry, cleaning, etc. Dripping can be avoided during the operation, and there is no need for extra attention or extra waiting time, thereby improving the user experience.

[0014] In a preferred embodiment, the control device is used to control the flow rate of the air pump in a single operation to be V3, the volume of the front water channel is V1, and the volume of the rear water channel is V2, satisfying V3>V1+V2.

[0015] By setting V3>V1+V2, the air pump can blow all the water in the entire supply pipe out of the supply pipe in a single operation, further reducing the probability of dripping when the cup assembly is taken out, and the structure is reliable.

[0016] In a preferred embodiment, the food processor further includes a movable part that can move relative to the cup assembly to have a working state and a non-working state, and a damping structure cooperating with the movable part, the damping structure is used to limit the movable part from switching from the working state to the non-working state after a preset time period, and the control device is used to control the air pump to operate within the preset time period.

[0017] By setting up a movable part and a damping structure, the damping structure is used to delay the state switching process of the movable part, forming a buffer time difference, that is, a preset duration. Under the control of the control device, the air pump can use the time difference of the movable part to complete the blowing action, so that the water in the front water channel is quickly blown into the rear water channel, forming scattered water droplets or forming water vapor to be discharged, which can prevent dripping during the separation of the cup assembly from the main unit. For the user, it is only necessary to follow the normal operation. For example, when the movable part is the machine cover, the user can normally remove the cup assembly for pouring, cleaning, etc. after the machine cover is fully opened. Since the air pump has completed the blowing work during the process of opening the machine cover, when the user removes the cup assembly after opening the machine cover, dripping can be avoided, and there is no need for extra attention or extra waiting, which improves the user experience.

[0018] In a preferred embodiment, the grinding cup is also provided with a liquid outlet, a valve body arranged at the liquid outlet, a valve core rotatably arranged in the valve body, and a motor driving the valve core. The motor is electrically connected to the control device, and the motor is used to drive the valve core to rotate to close the liquid outlet within the preset time period.

[0019] More preferably, the rotation speed S of the motor is set to: 18 rpm / min≤S≤25 rpm / min.

[0020] By providing a liquid outlet and a valve body, the valve core rotates within the valve body to control the opening and closing of the liquid outlet, thereby achieving automatic slurry discharge from the cup assembly. Users can choose to have the motor control the valve core to control the opening and closing of the liquid outlet according to a program, or they can choose to remove the cup assembly and then drain the slurry, which is more flexible. In addition, the motor is used to drive the valve core to rotate to close the liquid outlet within the preset time (opening time difference). This ensures that the valve core is in the position to close the liquid outlet when the user removes the cup assembly, preventing the liquid in the crushing cup from spilling.

[0021] Since it usually takes about 1.5 seconds to open the cover, by using a motor with a speed of 18rpm / min-25rpm / min, the motor can promptly and accurately rotate the valve core into place within the time difference of opening the cover to prevent liquid from spilling.

[0022] In a preferred embodiment, the control device is used to control the air pump to continue working until the water in the front water channel and the water in the rear water channel are blown into the grinding cup.

[0023] The working time of the air pump is controlled by the control device, so that the air pump continues to work until the water in the front water channel and the water in the rear water channel are blown into the grinding cup, so that when the user removes the cup assembly, the air pump blows all the water in the entire supply pipe out of the supply pipe, further reducing the probability of dripping when the cup assembly is taken out, and the structure is reliable.

[0024] In a preferred embodiment, the length L1 of the front water channel and the length L2 of the rear water channel satisfy: L1 / L2≤1 / 2.

[0025] By ensuring that the length ratio of the front water channel and the rear water channel meets the requirement of L1 / L2≤1 / 2, L1 is shortened relative to L2, allowing the air pump to blow the water from the front water channel to the rear water channel in a shorter time. The one-way valve is located in the front 1 / 3 of the entire supply pipe, effectively preventing the backflow of water in 2 / 3 of the supply pipe, further reducing the risk of water dripping.

[0026] In a preferred embodiment, the output connector is connected to a tee, the tee and the output end of the water pump are connected to a water supply path, the tee and the output end of the air pump are connected to an air supply path, and the length L3 of the water supply path and the length L4 of the air supply path satisfy L3≤L4.

[0027] By setting a three-way pipe, the three-way pipe is connected to the water pump and the air pump, so that the water pump and the air pump share a supply pipe to supply the corresponding medium to the grinding cup. Since there may be residual water in the water supply waterway, and the water supply waterway cannot be blown out by the air pump, the length L3 of the water supply waterway and the length L4 of the air supply waterway satisfy L3≤L4, so that the length of the water supply waterway is reduced, the possibility of residual water in the water supply waterway is reduced, and the water in the water supply waterway is prevented from flowing back to the water pump or breeding bacteria.

[0028] In a preferred embodiment, the supply port is opened on the side wall of the grinding cup, and the rear water channel is connected to the supply port and is vertically arranged close to the side wall of the grinding cup.

[0029] By opening the supply port on the side wall of the crushing cup and the rear water channel being arranged vertically and close to the side wall of the crushing cup, when the water pump is used to supply water to the crushing cup, the water flow can receive the heat radiation of the crushing cup, thereby increasing the temperature of the liquid entering the crushing cup, realizing the preheating of the pulping water or the cleaning water, speeding up the pulping process and shortening the pulping time during pulping, and improving the cleaning effect during cleaning.

[0030] In a preferred embodiment, the front water channel includes a vertical section connected to the coupling joint and a bent section bent laterally from the top end of the vertical section, and the one-way valve is located at the end of the bent section.

[0031] By setting the front water channel to include a vertical section and a bent section that bends horizontally from the top of the vertical section, the probability of water dripping downward can be reduced compared to the front water channel adopting a straight vertical structure. There are a small number of water droplets in the current water channel, and the water droplets can temporarily exist on the inner wall of the bent section or the vertical section without dripping. A one-way valve is set at the end of the bent section to effectively prevent the water entering the rear water channel from flowing back and dripping. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] like Figure 1-5 As shown, the present invention provides a food processing machine with reliable structure in embodiment 1, including a main unit 10 and a cup assembly 50, as shown in FIG. Figure 1-3As shown, the cup assembly 50 can be detachably mounted on the host 10. The host 10 is provided with a control device, a water pump 20 and an air pump 30 controlled by the control device, and an output connector 40. The output ends of the water pump 20 and the air pump 30 are both connected to the output connector 40. The cup assembly 50 includes a crushing cup 51 provided with a supply port, a supply pipe 52, and a coupling connector 53. The coupling connector 53 is plugged into and matched with the output connector 40 to achieve communication. The supply pipe 52 is connected between the supply port and the coupling connector 53. A one-way valve 523 is provided in the supply pipe 52. The one-way valve 523 separates the supply pipe 52 into a front water channel 521 and a rear water channel 522. The water pump 20 outputs water through the output connector 40 so that the water flows through the front water channel 521 and the rear water channel 522 in sequence and enters the crushing cup 51. The air pump 30 is used to blow the water in the front water channel 521 to the rear water channel 522 before the cup assembly 50 is separated from the host 10.

[0046] The present invention provides a food processing machine with reliable structure. By detachably mounting the cup assembly 50 on the main unit 10, the user can remove the cup assembly 50 and pour out the slurry after preparing thick slurry, so as to prevent the thick slurry from clogging the drain valve. The machine is flexible to use. By arranging a water pump 20 and an air pump 30, the output ends of the water pump 20 and the air pump 30 are both connected to the output connector 40. The cup assembly 50 includes a crushing cup 51 with a supply port, a supply pipe 52, and a coupling connector 53. The coupling connector 53 is plugged into and matched with the output connector 40 to achieve communication. The supply pipe 52 is connected between the supply port and the coupling connector 53. Therefore, the water pump 20 and the air pump 30 share the supply pipe 52 to supply the corresponding medium to the crushing cup 51. The machine has a compact structure. A one-way valve 523 is arranged in the supply pipe 52. The one-way valve 523 separates the supply pipe 52 into a front water channel 521 and the rear water channel 522, the water pump 20 outputs water through the output connector 40 so that the water flows through the front water channel 521 and the rear water channel 522 in sequence and enters the grinding cup 51. The one-way valve 523 can be used to realize one-way flow of water and prevent water from flowing back to the water pump 20 or the air pump 30. At the same time, the air pump 30 is used to blow the water in the front water channel 521 to the rear water channel 522 before the cup assembly 50 is separated from the main unit 10. The one-way valve 523 isolates the front water channel 521 and the rear water channel 522. Therefore, the one-way valve 523 can block the backflow and dripping of water after the water is blown to the rear water channel 522, and will not affect the plugging and unplugging of the cup assembly 50. While preventing the user from removing the cup assembly 50 and dripping, it also realizes easy installation of the cup assembly 50, and the one-way valve 523 will not be loosened by frequent friction at the plugging and unplugging position, and the anti-leakage effect is reliable.

[0047] The present invention does not limit the specific working mode of the air pump 30, for example:

[0048] Implementation Example 1, such as Figure 1-5As shown, the food processor further includes a movable member that can move relative to the cup assembly to have an operating state and a non-operating state, and a detection device that can detect the state of the movable member. The detection device is connected to the control device, and the control device is configured to control the operation of the air pump 30 after the detection device detects that the movable member is in the non-operating state. More preferably, the main unit 10 includes a housing 11 and a cover 12 disposed above the housing 11. The cover 12 and the housing 11 form a mounting cavity for enclosing the cup assembly. The movable member is the cover 12. In the operating state, the cover 12 and the housing 11 form a mounting cavity for enclosing the cup assembly. In the non-operating state, the cover 12 is open relative to the housing 11.

[0049] Furthermore, in this embodiment, the cover 12 is hinged to the casing 11, and the host 10 also includes a button for controlling the opening and closing of the cover 12. A damping structure 14 is arranged between the casing 11 and the cover 12, such as a damper, or the damping structure 14 includes two damping ribs that frictionally cooperate with each other, and the two damping ribs are respectively arranged on the cover 12 and the host 10; the damping structure 14 is arranged so that the cover 12 is fully opened relative to the cover 12 after a preset time after the button is triggered, and the control device is used to control the air pump 30 to operate within the preset time.

[0050] In this embodiment, the detection device optionally includes a safety switch that is triggered only when the cover 12 is in the operating state. When the cover is in the non-operating state, the safety switch is not turned on. Of course, the present invention does not limit the structure of the detection device. The detection device can also optionally detect the operation of the movable part, such as detecting whether a button is pressed. In addition, the detection device can also be a position sensor to directly detect the position of the movable part. The structure of the detection device is still applicable to other embodiments.

[0051] Specifically, in this embodiment, the volume of the front water channel 521 is V1, the volume of the rear water channel 522 is V2, and the flow rate of the air pump 30 in a single operation is V3, wherein V3>V1+V2.

[0052] Preferably, the air pump 30 works once within the above-mentioned preset time length, so that the working time of the air pump 30 and the lid opening time difference are synchronized, and all the water in the front water channel 521 and the rear water channel 522 can be blown away.

[0053] By setting V3>V1+V2, the air pump 30 can blow all the water in the entire supply pipe 52 out of the supply pipe 52 within the time difference when the user opens the lid, further reducing the probability of dripping when the cup assembly 50 is taken out, and the structure is reliable.

[0054] It should be noted that in this embodiment, V3>V1+V2 is preferably set, and the working time of the air pump 30 is synchronized with the time difference of opening the lid, and all the water in the front water channel 521 and the rear water channel 522 can be blown away. In fact, in this embodiment, it is also optional that the air pump 30 is only used to quickly blow air into the front water channel 521 so that at least part of the water in the front water channel 521 enters the rear water channel 522, and the water in the front water channel 521 is blown away into droplets, avoiding the problem of dripping when the user takes the cup. Whether the air pump blows away the water in the entire supply pipe, blows away the water in the front water channel alone, or blows away part of the water in the front water channel, the air pump can work in a very short time to avoid the dripping problem. The air pump is simple to select, simple to control, reduces costs, and simplifies the overall structure.

[0055] It should also be noted that the air pump 30 provided by the present invention is not limited to blowing the water flow in the front water channel 521 dry. In fact, the air pump 30 can also be used to blow gas into the grinding cup 51 after pulping to accelerate the cooling of the pulp, so that the user can drink it quickly; or, the air pump 30 is used to continuously blow air into the grinding chamber to accelerate the drying of the grinding cup 51 after cleaning.

[0056] In this embodiment, the machine cover 12 and the housing 11 are used to form an installation cavity for enclosing the cup assembly 50, so as to achieve full wrapping of the cup assembly 50 and reduce the working noise of the cup assembly 50. By arranging a damping structure 14 between the housing 11 and the machine cover 12, the opening of the machine cover 12 can be buffered, thereby improving the structural reliability. After the button 13 is triggered, the machine cover 12 is fully opened relative to the machine cover 12 after a preset period of time, i.e., a cover opening time difference is formed. Under the control of the control device, the air pump 30 can use the cover opening time difference to complete the blowing action, so that the water in the front water channel 521 is quickly blown into the rear water channel 522 to form scattered water droplets or form water vapor to be discharged, which can prevent the cup assembly 50 from dripping during the separation from the main unit 10. For the user, it is only necessary to press the button 13 to open the cover according to the normal operation, and then wait for the machine cover 12 to be fully opened to take out the cup assembly 50 normally for pouring pulp, cleaning, etc., so that dripping can be avoided during the operation, and there is no need for extra attention or extra waiting time, thereby improving the user experience.

[0057] In this embodiment, the pulverizing cup 51 preferably further comprises a liquid outlet, a valve body 54 disposed at the liquid outlet, a valve core 55 rotatably disposed within the valve body 54, and a motor 56 for driving the valve core 55. The motor 56 is electrically connected to the control device and is configured to rotate the valve core 55 within a predetermined time period to close the liquid outlet. More preferably, the speed S of the motor 56 is set to: 18 rpm / min ≤ S ≤ 25 rpm / min.

[0058] More specifically, if Figure 5As shown, the control device includes a main control unit, an air pump control unit, a water pump control unit, a valve core control unit, and a machine cover detection unit that are electrically connected to each other, so as to utilize the opening time difference of the machine cover when it is delayed to open, to control the valve core and the air pump, so as to achieve the purpose of closing the liquid outlet and clearing the front water channel, and avoid the problem of leakage caused by the user lifting the cup assembly.

[0059] By providing a liquid outlet and valve body 54, the valve core 55 rotates within the valve body 54 to control the opening and closing of the liquid outlet, thereby achieving automatic slurry discharge from the cup assembly 50. The user can choose to have the motor 56 control the valve core 55 according to the program to achieve the opening and closing control of the liquid outlet, or can choose to remove the cup assembly 50 and then drain the slurry, which is more flexible. In addition, the motor 56 is used to drive the valve core 55 to rotate to close the liquid outlet within a preset time (the time difference between opening the lid). This ensures that the valve core 55 is in the position to close the liquid outlet when the user removes the cup assembly 50, preventing the liquid in the grinding cup 51 from spilling. In this embodiment, the angle of the cover 12 from closed to fully open is 90 degrees, and the time it takes for the cover 12 to open is about 1.5S. Specifically, the time between the user pressing the button 13 and the cover 12 being fully opened relative to the housing 11 is the time it takes for the cover 12 to open. Therefore, by adopting a motor 56 with a rotation speed of 18rpm / min-25rpm / min, the motor 56 can timely and accurately rotate the valve core 55 into place within the time difference of opening the cover to prevent liquid from spilling.

[0060] In this implementation example, for example Figure 4 As shown, the length L1 of the front water channel 521 and the length L2 of the rear water channel 522 satisfy: L1 / L2≤1 / 2.

[0061] By ensuring that the length ratio of the front water channel 521 and the rear water channel 522 satisfies L1 / L2≤1 / 2, L1 is shortened relative to L2, so that the air pump 30 can blow the water from the front water channel 521 to the rear water channel 522 in a shorter time. The one-way valve 523 is located in the front 1 / 3 of the entire supply pipe 52, effectively preventing the water from flowing back into the supply pipe 522 / 3, further reducing the risk of water dripping.

[0062] In fact, in other implementation examples, preferably, L1 is smaller than L2, which can effectively achieve the purpose of reducing the risk of water dripping.

[0063] In this implementation example, Figure 4 As shown, the supply port is opened on the side wall of the grinding cup 51 , and the rear water channel 522 is connected to the supply port and is vertically arranged close to the side wall of the grinding cup 51 .

[0064] By opening the supply port on the side wall of the crushing cup 51, the rear water channel 522 is vertically arranged and close to the side wall of the crushing cup 51. Therefore, in the process of using the water pump 20 to supply water to the crushing cup 51, the water flow can receive the heat radiation of the heating crushing cup 51, thereby increasing the temperature of the liquid entering the crushing cup 51, realizing the preheating of the pulping water or the cleaning water, speeding up the pulping process and shortening the pulping time when pulping, and improving the cleaning effect when cleaning.

[0065] Preferably, the front water channel 521 includes a vertical section connected to the coupling joint 53 and a bent section bent laterally from the top of the vertical section, and the one-way valve 523 is located at the end of the bent section.

[0066] By setting the front water channel 521 to include a vertical section and a bent section that bends horizontally from the top of the vertical section, the probability of water dripping downward can be reduced compared to the front water channel 521 adopting a straight vertical structure. If there are a small amount of water droplets in the current water channel 521, the water droplets can temporarily exist on the inner wall of the bent section or the vertical section without dripping. The one-way valve 523 is set at the end of the bent section to effectively prevent the water entering the rear water channel 522 from flowing back and dripping.

[0067] Implementation Example 2 is different from Implementation Example 1 in that the operation of the air pump and the opening and closing of the machine cover are not directly related. In this implementation example, the control device is set to set the program of the food processor, such as the pulping stage, the cleaning stage, etc. After all the actions involving water intake in the current program (pulping stage or cleaning stage) are completed, the control device controls the air pump to start blowing, or delays for t time and controls the air pump to blow.

[0068] Preferably, the control device is used to control the air pump 30 to continue working until the water in the front water channel 521 and the water in the rear water channel 522 are blown into the grinding cup 51.

[0069] Specifically, the food processor also includes a humidity detector and an alarm for detecting the humidity in the front water channel 521. When the control device detects that the detection index of the humidity monitor reaches a preset value, the air pump 30 is controlled to stop working, and the alarm prompts the user to remove the cup assembly 50.

[0070] Preferably, in this embodiment, the control device is used to control the flow rate of the air pump for a single operation to be V3, the volume of the front water channel is V1, and the volume of the rear water channel is V2, satisfying V3>V1+V2.

[0071] The working time of the air pump 30 is controlled by the control device, so that the air pump 30 continues to work until the water in the front water channel 521 and the water in the rear water channel 522 are blown into the grinding cup 51, so that when the user removes the cup assembly 50, the air pump 30 blows all the water in the entire supply pipe 52 out of the supply pipe 52, further reducing the probability of dripping when the cup assembly 50 is taken out, and the structure is reliable.

[0072] Example 3: This example operates in a similar manner to the air pump of Example 1, differing only in that the movable member is a cup lid, which rotates and engages over the rim of the grinding cup. Optionally, the cup lid is provided with a magnet, and the detection device is a Hall effect element or reed switch that detects whether the cup lid is properly closed.

[0073] Implementation example 4. In this implementation example, the food processor also includes a movable part that can move relative to the cup assembly to have a working state and a non-working state, and a damping structure that cooperates with the movable part. The damping structure is used to limit the movable part from switching from the working state to the non-working state after a preset time period, and the control device is used to control the air pump to work within the preset time period.

[0074] This embodiment provides a movable part and a damping structure, utilizing the damping structure to delay the state switching process of the movable part, thereby forming a buffer time difference, i.e., a preset duration. Under the control of the control device, the air pump can utilize the time difference of the movable part's movement to complete the blowing action, so that the water in the front water channel is quickly blown into the rear water channel, forming scattered water droplets or forming water vapor to be discharged, which can prevent dripping during the separation of the cup assembly from the main unit. For the user, only conventional operations are required. For example, if the movable part is a machine cover, the user can remove the cup assembly normally after the machine cover is fully opened to pour pulp, clean it, etc. Because the air pump has completed the blowing work during the machine cover opening process, the user can avoid dripping when removing the cup assembly after the machine cover is opened, without the need for additional attention or waiting, thus improving the user experience.

[0075] It will be appreciated that the movable member in this embodiment can be a cover similar to that in Embodiment 1. When in operation, the cover 12 forms a mounting cavity with the housing 11 to enclose the cup assembly. When in non-operation, the cover 12 is open relative to the housing 11. Accordingly, a damping structure 14 is disposed between the housing 11 and the cover 12. For example, the damping structure 14 may be a damper, or include two frictionally engaged damping ribs, one disposed on the cover 12 and the other on the main unit 10.

[0076] Of course, in this embodiment, the movable part can also be a cup cover that covers the mouth of the crushing cup. Correspondingly, the damping structure is a sealing ring arranged on the cup cover. The sealing ring and the crushing cup have an interference fit. During the process of opening the cup cover, the sealing ring and the crushing cup frictionally cooperate to extend the opening time.

[0077] Implementation Example 5, such as Figure 6 As shown, the output connector 40 is connected to a tee, the tee and the output end of the water pump 20 are connected to the water supply path, and the tee and the output end of the air pump 30 are connected to the air supply path, and the length L3 of the water supply path and the length L4 of the air supply path satisfy L3≤L4.

[0078] By setting a three-way pipe, the three-way pipe is connected to the water pump 20 and the air pump 30, so that the water pump 20 and the air pump 30 share the supply pipe 52 to supply the corresponding medium to the grinding cup 51. Since there may be residual water in the water supply waterway, and the water supply waterway cannot be blown out by the air pump 30, the length L3 of the water supply waterway and the length L4 of the air supply waterway satisfy L3≤L4, so that the length of the water supply waterway is reduced, the possibility of residual water in the water supply waterway is reduced, and the water in the water supply waterway is prevented from flowing back to the water pump 20 or breeding bacteria.

[0079] Preferably, the water supply circuit and the air supply circuit are respectively provided with a one-way valve 523 .
