Description

Technical Field

[0001] The invention relates to the technical field of food processing machines, and in particular to a control method for a pulp discharge valve, a pulp discharge valve, a food processing machine and a storage medium. Background Art

[0002] Food processors such as food processors and wall breaking machines are provided with a pulp discharge valve, which includes a discharge pipe. When the discharge pipe is clamped, the pulp discharge valve is closed, and when the discharge pipe is loosened, the pulp discharge valve is opened. When the pulp discharge valve is opened, the processed food pulp can be discharged through the pulp discharge valve for consumption by users.

[0003] After the food processor is used, the discharge pipe is usually clamped to prevent dirt such as dust and insects from entering the food processor through the discharge pipe. If the food processor has not been used for a long time, the discharge pipe will always be in a clamped state, and the deformation of the discharge pipe will always be the largest. The discharge pipe is more likely to be irreversibly deformed, and even the inner wall of the discharge pipe will stick together, reducing the service life of the discharge valve.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0050] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0051] An embodiment of the present invention provides a solution by adjusting the inner hole cross-sectional area of ​​the discharge pipe after the food processor is used to avoid the discharge pipe being in a clamped state or a fully open state. This prevents external dirt from entering the interior of the food processor to a certain extent, while avoiding the discharge pipe being in a clamped state all the time, thereby increasing the service life of the discharge valve.

[0052] like Figure 1 As shown, Figure 1 It is a schematic diagram of the terminal structure of the hardware operating environment involved in the embodiment of the present invention.

[0053] The terminal in the embodiment of the present invention is a slurry discharge valve.

[0054] like Figure 1As shown, the terminal may include: a processor 1001, such as a CPU, a communication bus 1002, and a memory 1003. The communication bus 1002 is used to realize the connection and communication between these components. The memory 1003 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1003 may also be a storage device independent of the aforementioned processor 1001.

[0055] Those skilled in the art will understand that Figure 1 The terminal structure shown in the figure does not constitute a limitation on the terminal, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0056] like Figure 1 As shown, the memory 1003 as a computer storage medium may include a control program for the slurry discharge valve.

[0057] exist Figure 1 In the terminal shown, the processor 1001 can be used to call the control program of the slurry discharge valve stored in the memory 1003 and perform the following operations:

[0058] After detecting that the discharge pipe has finished discharging or cleaning, the driving component is controlled to drive the clamping component to move to adjust the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping component. The adjusted inner hole cross-sectional area is larger than the minimum inner hole cross-sectional area of ​​the discharge pipe and smaller than the maximum inner hole cross-sectional area of ​​the discharge pipe.

[0059] Further, the processor 1001 may call the control program of the slurry discharge valve stored in the memory 1003, and further perform the following operations:

[0060] Controlling the driving assembly to drive the clamping assembly to move in a second direction, so as to reduce the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly to a minimum inner hole cross-sectional area;

[0061] When it is detected that the food processor where the discharge pipe is located is powered off or enters a standby state, the duration of the power off or standby state of the food processor where the discharge pipe is located is obtained;

[0062] When the duration is greater than a first preset duration, the driving assembly is controlled to drive the clamping assembly to move in a first direction to increase the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly, and the increased inner hole cross-sectional area is smaller than the maximum inner hole cross-sectional area of ​​the discharge pipe.

[0063] Further, the processor 1001 may call the control program of the slurry discharge valve stored in the memory 1003, and further perform the following operations:

[0064] When it is detected that the food processor where the discharge pipe is located is powered on or exits the standby state or is operated by the user, the driving component is controlled to drive the clamping component to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping component to the minimum inner hole cross-sectional area.

[0065] Further, the processor 1001 may call the control program of the slurry discharge valve stored in the memory 1003, and further perform the following operations:

[0066] When a control instruction is received within a second preset time period, executing a control operation corresponding to the control instruction;

[0067] After the control operation is completed, the step of controlling the driving component to drive the clamping component to move so as to adjust the cross-sectional area of ​​the inner hole of the discharge pipe clamped by the clamping component is returned to be executed.

[0068] Further, the processor 1001 may call the control program of the slurry discharge valve stored in the memory 1003, and further perform the following operations:

[0069] When no control instruction is received within the second preset time period, return to the step of obtaining the duration of the food processor where the discharge pipe is located being powered off or in the standby state when it is detected that the food processor where the discharge pipe is located is powered off or enters the standby state.

[0070] Further, the processor 1001 may call the control program of the slurry discharge valve stored in the memory 1003, and further perform the following operations:

[0071] When it is detected that the discharge pipe starts to discharge or the discharge pipe is cleaned, the driving component is controlled to drive the clamping component to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping component, and the reduced inner hole cross-sectional area is larger than the minimum inner hole cross-sectional area of ​​the discharge pipe;

[0072] After reducing the inner hole cross-sectional area, the driving assembly is controlled to drive the clamping assembly to move in the first direction to increase the inner hole cross-sectional area of ​​the discharge pipe position clamped by the clamping assembly.

[0073] Further, the processor 1001 may call the control program of the slurry discharge valve stored in the memory 1003, and further perform the following operations:

[0074] The control driving assembly drives at least one of the first clamping arm and the second clamping arm to move, so as to adjust the inner hole cross-sectional area of ​​the discharge pipe clamped by the first clamping arm and the second clamping arm.

[0075] In one embodiment, the control method of the slurry discharge valve comprises the following steps:

[0076] Step S10, after detecting that the discharge pipe has finished discharging or cleaning, control the driving component to drive the clamping component to move to adjust the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping component, and the adjusted inner hole cross-sectional area is smaller than the maximum inner hole cross-sectional area of ​​the discharge pipe.

[0077] In this embodiment, a food processor, a wall-breaking machine and other food processing machines are provided with a slurry discharge valve, which includes a discharge pipe. The discharge pipe is used to discharge the slurry from the discharge pipe after the food is processed into slurry, i.e., discharge. After the discharge is completed, clean water or a cleaning agent can be discharged from the discharge pipe to rinse the slurry stuck on the inner wall of the discharge pipe, i.e., to clean. The discharge pipe is a soft pipe, and can be deformed when subjected to external force, thereby changing the inner hole cross-sectional area of ​​the discharge pipe at the position subjected to external force. The slurry discharge valve also includes a clamping assembly and a driving assembly. The clamping assembly clamps the discharge pipe to apply external force to the discharge pipe. The driving assembly is connected to the clamping assembly. The driving assembly is used to drive the clamping assembly to move, so that the clamping assembly applies external force to the discharge pipe or stops applying external force, thereby adjusting the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly.

[0078] Optionally, since the food processing of the food processing machine is an automated process, the food processing process of the food processing machine may be monitored to detect whether the discharge pipe has currently finished discharging or whether cleaning has been completed.

[0079] Optionally, after detecting that the discharge pipe has finished discharging or cleaning, the drive assembly is directly controlled to drive the clamping assembly to move, so as to adjust the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly, and the adjusted inner hole cross-sectional area is larger than the minimum inner hole cross-sectional area of ​​the discharge pipe, so as to avoid the discharge pipe being in a clamped state and reducing the service life of the discharge pipe, and the adjusted inner hole cross-sectional area is smaller than the maximum inner hole cross-sectional area of ​​the discharge pipe, so as to avoid the discharge pipe being in a fully open state, causing a large amount of external bacteria, dust, etc. to enter the interior of the food processor through the discharge pipe, for example, the adjusted discharge pipe is in a half-open state.

[0080] Optionally, the clamping assembly may include only one clamping arm. Since the position of the discharge port and the feed port of the discharge pipe are usually fixed by other structures of the food processor, the clamping arm of the clamping assembly may be arranged between the discharge port and the feed port. When the driving assembly drives the clamping arm to move, since the positions of the discharge port and the feed port of the discharge pipe are fixed, the clamping arm may press or stop pressing the discharge pipe, thereby adjusting the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly. Optionally, the clamping assembly includes a first clamping arm and a second clamping arm that are relatively arranged, and the discharge pipe passes between the first clamping arm and the second clamping arm. The driving assembly is connected to at least one of the first clamping arm and the second clamping arm, and the driving assembly is used to drive at least one of the first clamping arm and the second clamping arm to move so as to adjust the inner hole cross-sectional area of ​​the discharge pipe clamped by the first clamping arm and the second clamping arm. Therefore, when controlling the driving assembly to drive the clamping assembly to move so as to adjust the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly, the driving assembly can be controlled to drive at least one of the first clamping arm and the second clamping arm to move, so that the first clamping arm moves and approaches or moves away from the second clamping arm, or the second clamping arm moves and approaches or moves away from the first clamping arm, or both the first clamping arm and the second clamping arm move, and the first clamping arm and the second clamping arm approach or move away from each other, thereby realizing the adjustment of the inner hole cross-sectional area of ​​the discharge pipe position clamped by the clamping assembly.

[0081] In the technical solution disclosed in this embodiment, after the food processor is used, the inner hole cross-sectional area of ​​the discharge pipe is adjusted to prevent the discharge pipe from being in a clamped state or a fully open state. This prevents external dirt from entering the interior of the food processor to a certain extent, while preventing the discharge pipe from being in a clamped state all the time, thereby increasing the service life of the discharge valve.

[0082] In another embodiment, if Figure 2 As shown, based on the above embodiment, the step of controlling the driving assembly to drive the clamping assembly to move in step S10 to adjust the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly includes:

[0083] Step S11, controlling the driving assembly to drive the clamping assembly to move in the second direction, so as to reduce the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly to the minimum inner hole cross-sectional area;

[0084] In this embodiment, since the user may use the food processor again in a short period of time after the discharge pipe is finished discharging or cleaning, in order to avoid frequently controlling the drive component to drive the clamping component to move, after detecting that the discharge pipe is finished discharging or cleaning, the drive component can be controlled to drive the clamping component to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping component to the minimum inner hole cross-sectional area, that is, the discharge pipe clamped by the clamping component is in a closed state, wherein the minimum inner hole cross-sectional area can be zero, so as to close the discharge pipe and prevent external dust, insects and other dirt from entering the interior of the food processor through the discharge pipe.

[0085] Step S12, when it is detected that the food processor where the discharge pipe is located is powered off or enters a standby state, obtaining the duration of the power off or standby state of the food processor where the discharge pipe is located;

[0086] In this embodiment, since the food processor will automatically enter the standby mode when it has not been used for a period of time, it can be considered that the user may not use the food processor in the short term, or considering that some users have the habit of unplugging the power directly after using the food processor, when it is detected that the food processor is powered off, it can be considered that the user may not use the food processor in the short term. Therefore, when it is detected that the food processor where the discharge pipe is located is powered off or enters the standby state, the timing can be started to obtain the duration of the food processor being powered off or in the standby state, and it can be judged whether the user will indeed not use the food processor in the short term based on the duration.

[0087] Step S13, when the duration is greater than a first preset duration, control the driving assembly to drive the clamping assembly to move in a first direction to increase the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly, and the increased inner hole cross-sectional area is smaller than the maximum inner hole cross-sectional area of ​​the discharge pipe.

[0088] In this embodiment, when the duration is greater than the first preset duration, indicating whether the user will indeed not use the food processor in the short term, the driving component can be controlled to drive the clamping component to move in the first direction to increase the inner hole cross-sectional area of ​​the discharge tube clamped by the clamping component, the increased inner hole cross-sectional area is smaller than the maximum inner hole cross-sectional area of ​​the discharge tube, and the increased inner hole cross-sectional area is larger than the minimum inner hole cross-sectional area of ​​the discharge tube, that is, the discharge tube clamped by the clamping component is in a partially open state.

[0089] Optionally, when the duration is less than a first preset duration, if a control instruction for the food processor is received and a control operation corresponding to the control instruction is executed, and after the control operation is completed, the control driving component is returned to drive the clamping component to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge tube clamped by the clamping component to the minimum inner hole cross-sectional area.

[0090] Optionally, if the first preset time is too long, it will have little effect on improving the life of the discharge pipe. If the first preset time is too short, the drive assembly may be controlled too frequently to drive the clamping assembly to move. Therefore, based on the user habits of the food processor, the first preset time can be set within the range of 1 to 30 days, preferably within the range of 3 to 20 days, and more preferably within the range of 5 to 15 days, which will better improve the service life of the discharge pipe.

[0091] Optionally, in order to prevent the discharge tube from being in the same deformation state for a long time, after controlling the drive assembly to drive the clamping assembly to move in the first direction to increase the inner hole cross-sectional area of ​​the discharge tube clamped by the clamping assembly, the duration of the food processor where the discharge tube is located being powered off or in standby mode can be restarted at regular intervals, and when the duration is greater than the first preset duration, the drive assembly is controlled to drive the clamping assembly to move in the second direction or the first direction to change the deformation state of the discharge tube and increase the service life of the discharge tube.

[0092] In the technical solution disclosed in this embodiment, after detecting that the discharge pipe has finished discharging or cleaning, the discharge pipe is closed first, and when it is determined that the user will not use the food processor again in a short period of time, the inner hole cross-sectional area is adjusted to be larger than the minimum inner hole cross-sectional area and smaller than the maximum inner hole cross-sectional area, so as to avoid the driving component frequently driving the clamping component to move when the user uses the food processor multiple times in a short period of time.

[0093] In yet another embodiment, Figure 3 As shown, in Figure 2 On the basis of the above, after step S13, the following steps are further included:

[0094] Step S20, when it is detected that the food processor where the discharge pipe is located is powered on or exits the standby state or is operated by the user, the driving component is controlled to drive the clamping component to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping component to the minimum inner hole cross-sectional area.

[0095] In this embodiment, after the control drive component drives the clamping component to move in the first direction to increase the inner hole cross-sectional area of ​​the discharge tube clamped by the clamping component, if it is detected that the food processor is powered on or exits the standby state or the user operates, it indicates that the user may be about to use the food processor. At this time, the control drive component can be turned off to drive the clamping component to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge tube clamped by the clamping component to the minimum inner hole cross-sectional area, that is, the discharge tube clamped by the clamping component is in a partially open state to close the discharge tube to prevent the food from flowing out of the discharge tube when the user adds the food to be processed into the food processor.

[0096] Optionally, since the food processor is powered on or exits the standby state or the user operation may be caused by the user's misoperation, for example, the user moves the food processor to another location, the food processor is powered on, or the user accidentally touches the control panel and triggers a non-food processing control instruction, and the food processor exits the standby state, therefore, after closing the discharge pipe, it can be detected whether the food processing control instruction triggered by the user is received within the second preset time length. If the food processing control instruction is received within the second preset time length, the control operation corresponding to the control instruction is executed to meet the user's food processing needs, and after the control operation is executed, the step of controlling the driving component to drive the clamping component to move to adjust the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping component is returned. If the control instruction is not received within the second preset time length, it indicates that the food processor is powered on or exits the standby state or the user operation is a user misoperation, therefore, it can be returned to execute the step of obtaining the continuous time of the food processor where the discharge pipe is located being powered off or in the standby state when it is detected that the food processor where the discharge pipe is located is powered off or enters the standby state, so as to re-judge whether the user will not use the food processor again in the short term.

[0097] In the technical solution disclosed in this embodiment, when it is detected that the food processor where the discharge pipe is located is powered on or exits the standby state or is operated by the user, the discharge pipe is closed to prevent the food from flowing out of the discharge pipe when the user adds the food to be processed into the food processor.

[0098] In yet another embodiment, Figure 4 As shown, in Figures 2 to 3 Based on any of the embodiments, before step S10, the following step may be further included:

[0099] Step S30, when it is detected that the discharge pipe starts to discharge or the discharge pipe is cleaned, the driving assembly is controlled to drive the clamping assembly to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly, and the reduced inner hole cross-sectional area is greater than the minimum inner hole cross-sectional area of ​​the discharge pipe;

[0100] In this embodiment, the discharge pipe will discharge or clean the discharge pipe before the discharge or cleaning is completed. Therefore, when it is detected that the discharge pipe starts to discharge or clean the discharge pipe, the drive component can be controlled to drive the clamping component to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping component. After reducing the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping component, it can be known from fluid knowledge that the same water flow will flow through a smaller inner hole cross-sectional area, and the flow rate will increase, so the flushing effect on the inner wall of the discharge pipe is stronger, that is, the cleaning ability of the flushing water is enhanced, and the same food juice will flow through a smaller inner hole cross-sectional area, and the flow rate will also increase, thereby reducing the adhesion of the juice on the inner wall of the discharge pipe, thereby achieving the purpose of cleaning the inner wall of the discharge pipe.

[0101] Optionally, the reduced cross-sectional area of ​​the inner hole is larger than a preset area to avoid the cross-sectional area of ​​the inner hole being too small, thereby affecting normal discharge or flushing of the discharge pipe.

[0102] Step S40, after reducing the inner hole cross-sectional area, controlling the driving assembly to drive the clamping assembly to move in the first direction to increase the inner hole cross-sectional area of ​​the discharge pipe position clamped by the clamping assembly.

[0103] In this embodiment, after the driving assembly is controlled to drive the clamping assembly to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly, the driving assembly can be controlled to drive the clamping assembly to move in the first direction immediately or after a preset time to increase the inner hole cross-sectional area of ​​the discharge pipe position clamped by the clamping assembly. By reducing and increasing the inner hole cross-sectional area, the discharge pipe is clamped and loosened, and the shape of the inner wall of the discharge pipe changes dynamically, and food slurry is more likely to adhere to the static wall surface. The dynamic change of the inner wall can make it more difficult for food slurry to adhere to the inner wall, thereby achieving the purpose of cleaning the inner wall of the discharge pipe.

[0104] Optionally, after controlling the driving component to drive the clamping component to move in the first direction to increase the inner hole cross-sectional area of ​​the discharge tube position clamped by the clamping component, the step of controlling the driving component to drive the clamping component to move in the second direction to reduce the inner hole cross-sectional area of ​​the discharge tube clamped by the clamping component is returned to implement repeated compression and relaxation of the discharge tube by the clamping component, and the shape of the inner wall of the discharge tube is constantly changed, making it more difficult for food juice to adhere to the inner wall, and enhancing the flushing effect of the water flow, thereby further improving the cleaning effect of the inner wall of the discharge tube.

[0105] Optionally, the control driving component drives the clamping component to reciprocate in the second direction and the first direction until a preset condition is reached and stops. The preset condition may include at least one of the following: detecting that the discharge of the discharge pipe is completed or the cleaning is completed, the duration of the movement of the clamping component driven by the driving component reaches a preset duration, and the number of times the driving component drives the clamping component to move in the second direction and / or the first direction reaches a preset number of times.

[0106] In the technical solution disclosed in the present embodiment, when it is detected that the discharge pipe starts to discharge or clean the discharge pipe, the control driving component drives the clamping component to repeatedly compress and relax the discharge pipe, and repeatedly reduce and increase the cross-sectional area of ​​the inner hole of the discharge pipe clamped by the clamping component. For food juice, due to the continuous change of the inner wall morphology of the discharge pipe and the increase in the flow rate of the food juice, the adhesion of the food juice on the inner wall of the discharge pipe is reduced. For clean water, since the flow rate of the clean water in the discharge pipe is also increased, the flushing ability of the clean water on the inner wall of the discharge pipe is enhanced, and the cleaning effect on the inner wall of the discharge pipe is improved.

[0107] based on Figures 2 to 4Based on the illustrated embodiments, the structures of the slurry discharge valve and the food processor are illustrated, but the structures of the slurry discharge valve and the food processor are not limited to the structures involved in the examples.

[0108] Reference Figures 5 to 10 , which is an example of the structure of a pulp discharge valve and a food processor.

[0109] Please refer to Figures 5 to 7 The slurry discharge valve 100 includes a bracket 110, a discharge pipe 130, a clamping assembly 150 and a driving assembly 170. The discharge pipe 130 is installed on the bracket 110, wherein the discharge pipe 130 can be made of a material with deformation recovery ability, such as a rubber tube, a silicone tube, etc. The discharge pipe 130 has an inlet 131 and an outlet 133, and the inlet 131 can be docked with a container in a household appliance. In one installation method, the discharge pipe 130 can be fixed to the outside of the bracket 110. In another installation method, the discharge pipe 130 can be, for example, clamped and installed on the bracket 110 in the manner shown in the figure, and is penetrated in the bracket 110. The clamping assembly 150 includes a first clamping arm 151 and a second clamping arm 153 arranged opposite to each other, and the first clamping arm 151 and the second clamping arm 153 are both rotatably connected to the bracket 110, and the discharge pipe 130 passes between the first clamping arm 151 and the second clamping arm 153. The driving assembly 170 is installed on the bracket 110, and the driving assembly 170 includes a driving member 171 and a transmission member 174. The transmission member 174 is provided with a first driving surface 1751 and a second driving surface 1761 set at an angle. The first clamping arm 151 is in sliding contact with the first driving surface 1751, and the second clamping arm 153 is in sliding contact with the second driving surface 1761.

[0110] The driving member 171 drives the transmission member 174 to move closer to or farther from the clamping assembly 150 , so that the first clamping arm 151 and the second clamping arm 153 can move closer to or farther from each other to close or open the discharge pipe 130 .

[0111] The bracket 110 of the present application is a sheet metal structure, which includes a limiting portion 111 and a mounting portion 113. A sliding groove 1111 with openings at both ends is formed in the limiting portion 111. The first clamping arm 151 and the second clamping arm 153 extend into the sliding groove 1111 from one opening, and the transmission member 174 extends into the sliding groove 1111 from the other opening. A rotating shaft 115 is also installed on the limiting portion 111. The first clamping arm 151 and the second clamping arm 153 are each provided with an assembly hole 155 at one end exposed from the sliding groove 1111. The first clamping arm 151 and the second clamping arm 153 are rotatably sleeved on the outside of the rotating shaft 115 through the assembly hole 155, thereby making the installation structure of the first clamping arm 151 and the second clamping arm 153 compact. The transmission member 174 includes a connecting portion 177 and a first transmission arm 175 and a second transmission arm 176 connected to the connecting portion 177. The connecting portion 177 is connected to the driving member 171. The first transmission arm 175 and the second transmission arm 176 are arranged at an angle, and the inner wall surfaces of the first transmission arm 175 and the second transmission arm 176 opposite to each other respectively form a first driving surface 1751 and a second driving surface 1761. That is, the first transmission arm 175 and the second transmission arm 176 of the present application form an eight-shaped shape, and the first clamping arm 151 and the second clamping arm 153 are also folded in the sliding groove 1111 due to the limitation of the sliding groove 1111, and also form an eight-shaped shape, and the ends of the first clamping arm 151 and the second clamping arm 153 are located on the inner side of the first transmission arm 175 and the second transmission arm 176 and respectively make sliding contact with the first driving surface 1751 and the second driving surface 1761. It can be understood that in other embodiments, the first clamping arm 151 and the second clamping arm 153 can form an eight-shaped structure, or the first clamping arm 151 and the second clamping arm 153 can be realized by connecting a torsion spring or a spring structure. Exceptionally, for the structural form of the transmission member 174, the structure of setting two transmission arms in the above content makes the structure of the entire device simple, and in other embodiments, the transmission member 174 can also include a connecting portion 177 and a trumpet-shaped structure with the connecting portion 177, and the first clamping arm 151 and the second clamping arm 153 can slide along the inner surface of the trumpet-shaped structure.

[0112] Please refer to Figures 8 to 10During use, when the driving member 171 drives the transmission member 174 to move close to the clamping assembly 150, under the pressure and guidance of the first driving surface 1751 and the second driving surface 1761, the ends of the first clamping arm 151 and the second clamping arm 153 move along the first driving surface 1751 and the second driving surface 1761 respectively, and then the first clamping arm 151 and the second clamping arm 153 will move closer to each other, so that the distance between the first clamping arm 151 and the second clamping arm 153 is reduced, thereby closing the channel in the discharge pipe 130. When the driving member 171 drives the transmission member 174 to move away from the clamping assembly 150, the activity space for the first clamping arm 151 and the second clamping arm 153 to open outward becomes larger, and due to the elastic restoring force of the structure of the discharge pipe 130 itself, the first clamping arm 151 and the second clamping arm 153 are driven to expand outward, and at this time, the channel inside the discharge pipe 130 can be connected. In combination with the above content, during the above movement process, the sliding groove 1111 in the bracket 110 limits the activity space of the first clamping arm 151 and the second clamping arm 153, so that they maintain the opening in the direction of the driving member 171 in an eight-shaped shape, thereby realizing the operation of repeatedly opening and closing the discharge pipe 130. It should be noted here that the above-mentioned structure in which a torsion spring or a spring is connected between the first clamping arm 151 and the second clamping arm 153 is applicable regardless of whether the sliding groove 1111 is provided. The torsion spring or the spring preferably provides the first clamping arm 151 and the second clamping arm 153 with a tendency to open outwards. Such a setting can reduce the load when the first clamping arm 151 and the second clamping arm 153 are opened when the elastic force generated by the mechanical fatigue of the discharge pipe 130 due to its long-term use is reduced, so that it can be opened smoothly.

[0113] The technical solution of this example is to set a first clamping arm 151 and a second clamping arm 153 that can approach or move away from each other in the slurry discharge valve 100, and set a first driving surface 1751 corresponding to the first clamping arm 151 and a second driving surface 1761 corresponding to the second clamping arm 153 through the transmission member 174 in the drive assembly 170, the first clamping arm 151 is in sliding contact with the first driving surface 1751, and the second driving arm is in sliding contact with the second driving surface 1761. Therefore, during the use of the food processor, when it is necessary to realize the opening and closing of the discharge pipe 130, when the drive assembly 170 drives the transmission member 174 to move toward the clamping assembly 150, the first clamping arm 151 slides along the first driving surface 1751, and similarly, the second clamping arm 153 slides along the second driving surface 1761. The driving surface 1751 and the second driving surface 1761 are set at an angle, so that the first clamping arm 151 and the second clamping arm 153 can approach each other to close the discharge pipe 130 when the transmission member 174 approaches the clamping assembly 150, and when away from the clamping assembly 150, the first clamping arm 151 and the second clamping arm 153 can move away from each other under the deformation drive of the discharge pipe 130 to open the discharge pipe 130. Because the discharge pipe 130 passes between the first clamping arm 151 and the second clamping arm 153, that is, the first clamping arm 151 and the second clamping arm 153 do not enter the pipeline of the discharge pipe 130, there will be no food residue during the use of the slurry discharge valve 100, which is more convenient to clean and more hygienic to use. It also saves the sealing design of the slurry discharge valve 100 device in the prior art, which can also reduce costs.

[0114] In one embodiment, the driving member 171 includes a driving motor 172 and a screw 173 mounted on the motor 172 shaft of the driving motor 172, and a transmission screw hole 1771 is provided on the connecting portion 177 to cooperate with the screw 173. The present application uses the driving motor 172 and the screw 173 as the driving member 171, so that the overall structure is compact and the driving process is reliable.

[0115] In one embodiment, the driving member 171 is a cylinder, and the connecting portion 177 is connected to the piston rod of the cylinder. The driving member 171 is in the form of a cylinder, which has the advantage of low manufacturing cost.

[0116] It can be understood that, in addition to the two structural forms listed above, the structural form of the driving member 171 of the present application can also be applied to other solutions that can be converted into a driving transmission member 174 for linear motion.

[0117] In order to make the movement of the first clamping arm 151 and the second clamping arm 153 smooth, the first clamping arm 151 and the second clamping arm 153 of the present invention are both formed with a guide arc surface 157 at one end close to the transmission member 174. By providing the guide arc surface 157 at the ends of the two clamping arms, on the one hand, the friction between them and the two driving surfaces is reduced, and on the other hand, it is not easy to scratch the driving surfaces.

[0118] In order to prevent leakage and ensure a secure seal after the discharge pipe 130 is closed, in one embodiment, at least one of the first clamping arm 151 and the second clamping arm 153 is provided with a rib 159 on the surface in contact with the discharge pipe 130. The present application provides ribs 159 on both the first clamping arm 151 and the second clamping arm 153, and the ribs 159 on the first clamping arm 151 and the second clamping arm 153 are staggered, so that the closing process of the discharge pipe 130 can be made more secure.

[0119] When the entire slurry discharge valve 100 of the present application is installed on an external device, it is achieved through the mounting portion 113 on the bracket 110, wherein the mounting portion 113 includes two supporting feet arranged opposite to each other, each supporting foot is provided with a mounting hole 1131, and the slurry discharge valve 100 can be fixed to the external device through a connecting piece passing through the mounting hole 1131. A limiting groove 1133 is formed between the two supporting feet, and the discharge pipe 130 extends out from the limiting groove 1133 after passing through the above-mentioned limiting portion 111. The design of the limiting groove 1133 can effectively protect the discharge pipe 130.

[0120] This example also proposes a food processor, which includes a container and a pulp discharge valve 100. The container is provided with a pulp discharge port, and a discharge pipe 130 in the pulp discharge valve 100 is connected to the pulp discharge port. The specific structure of the pulp discharge valve 100 refers to the above embodiment. Since the food processor adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0121] The food processor in this example can be a household appliance such as a soymilk machine, a wall breaking machine, a juicer, etc.

[0122] Reference Figures 11 to 20 , which is an example of the structure of a pulp discharge valve and a food processor.

[0123] Please refer to Fig.19 and Fig. 20 The food processing machine includes a cup body 210 , a discharge pipe 220 , a slurry discharge valve 100 , a frame 230 and a receiving cup 230 .

[0124] The cup body 210 is mounted on the upper part of the frame 230, and a discharge hole is opened at the bottom of the cup body 210. The discharge pipe 220 is connected to the cup body 210 and communicates with the discharge hole. The discharge valve 100 is mounted on the outside of the cup body 210, wherein the discharge valve 100 can be connected to the frame 230, or the discharge valve can be connected to the cup body 210. The discharge valve 100 is used to control the on-off of the discharge pipe 220, and thus can realize the automatic discharge process during the use of the food processor, for example, Fig. 20 In the embodiment, when the food processor has prepared the beverage, the discharge valve 100 controls the discharge pipe 220 to open, and the beverage in the cup body 210 is discharged through the discharge pipe 220 and falls into the receiving cup 230 .

[0125] In existing food processing machines, the structure of the slurry discharge valve often needs to be connected to the inner wall of the discharge pipe 220 to realize the conduction and closing of the discharge pipe 220 channel. Such a design makes the slurry discharge valve 100 inconvenient to clean, and the structure is relatively complex, resulting in a higher cost for the food processing machine. In this regard, this example also proposes a new slurry discharge valve 100 to solve the above problems.

[0126] Please refer to Figures 11 to 13 In this example, the slurry discharge valve 100 includes:

[0127] A clamping assembly 130, wherein the clamping assembly 130 includes a first clamping portion 131 and a second clamping portion 133 that can move closer to or farther from each other, and when the clamping assembly 130 is in a clamping state, the discharge pipe 220 passes between the first clamping portion 131 and the second clamping portion 133; and

[0128] The driving component 110, the driving member 111 component is transmission-connected with the clamping component 130. Under the drive of the driving component 110, the first clamping portion 131 and the second clamping portion 133 can approach each other and contact with the discharge pipe 220 to close the channel in the discharge pipe 220, or the first clamping portion 131 and the second clamping portion 133 can move away from each other to make the channel in the discharge pipe 220 open.

[0129] In the present application, the first clamping part 131 and the second clamping part 133 may be respectively located on two parts, and the driving assembly 110 may be transmission-connected with one of the two parts, driving one of the first clamping part 131 and the second clamping part 133 to move closer to or away from the other to achieve the pressing of the discharge pipe 220 to close or release to open, and the driving assembly 110 may also be transmission-connected with both parts, so that the first clamping part 131 and the second clamping part 133 may move simultaneously to move closer to or away from each other to close or open the channel in the discharge pipe 220. In some embodiments, the first clamping part 131 and the second clamping part 133 may also be located on one part and respectively located at different positions on one part, wherein the part may be, for example, a bendable plastic part, or a bendable metal part. In addition, the discharge pipe 220 is made of a flexible material, such as plastic, silicone, or rubber, so that the inner wall of the discharge pipe 220 can be fitted together when the first clamping portion 131 and the second clamping portion 133 are close to each other, thereby closing the channel in the discharge pipe 220. During use, the clamping assembly 130 of the present application can be configured to be swingable. For example, when the discharge pipe 220 needs to be closed, the clamping assembly 130 can be twisted and swung to the discharge pipe 220 to clamp the discharge pipe 220. When the discharge pipe 220 does not need to be closed, the clamping assembly 130 can be twisted and swung to other places. Of course, the clamping assembly 130 can also be fixed in a specific place so that it can clamp and close the discharge pipe 220 when needed.

[0130] The technical solution of this example is to provide a first clamping part 131 and a second clamping part 133 that can move closer to or away from each other in the slurry discharge valve 100, and drive the first clamping part 131 and the second clamping part 133 through the driving component 110. Therefore, during the use of the food processor, when it is necessary to realize the opening and closing of the discharge pipe 220, it is only necessary for the driving component 110 to drive the first clamping part 131 and the second clamping part 133 to move closer to or away from each other. In addition, because the discharge pipe 220 passes through the first clamping part 131 and the second clamping part 133 during the clamping process, that is, the first clamping part 131 and the second clamping part 133 do not enter the pipeline of the discharge pipe 220, there will be no food residue during the use of the slurry discharge valve 100, which is more convenient to clean and more hygienic to use. In addition, the sealing design of the slurry discharge valve 100 in the prior art is omitted, which can also reduce costs.

[0131] The present application prefers a solution in which the first clamping portion 131 and the second clamping portion 133 are respectively located on two parts. Optionally, the clamping assembly 130 includes a first clamping member 130a and a second clamping member 130b, the first clamping member 130a is provided with the first clamping portion 131, the second clamping member 130b is provided with the second clamping portion 133, the driving assembly 110 is connected to at least one of the first clamping member 130a and the second clamping member 130b, and the driving assembly 110 drives at least one of the first clamping member 130a and the second clamping member 130b to move so as to drive the first clamping portion 131 and the second clamping portion 133 to approach or move away from each other.

[0132] Please refer to Figures 11 to 13 In the first embodiment of the slurry discharge valve 100 of the present application, the first clamping member 130a and the second clamping member 130b are rotatably connected. The first clamping member 130a further includes a first driving portion 135, and the first driving portion 135 and the first clamping portion 131 are respectively located at opposite sides of the rotation connection, and the second clamping member 130b further includes a second driving portion 137, and the second driving portion 137 and the second clamping portion 133 are respectively located at opposite sides of the rotation connection; the driving assembly 110 is respectively connected to the first driving portion 135 and the second driving portion 137, and the driving assembly 110 drives the first clamping portion 131 and the second clamping portion 133 to move simultaneously to approach or move away from each other.

[0133] In this embodiment, the middle parts of the first clamping member 130a and the second clamping member 130b are rotatably connected by a pivot 139, and the first clamping member 130a and the second clamping member 130b can swing around the pivot 139, wherein the pivot 139 can be fixed to the cup body 210 or the frame 230. The driving assembly 110 drives the first driving part 135 and the second driving part 137 to make the first clamping part 131 and the second clamping part 133 move simultaneously and move closer to and away from each other to realize the opening and closing of the discharge pipe 220.

[0134] In the scheme where the driving assembly 110 drives both the first clamping member 130a and the second clamping member 130b to move, Figures 11 to 13In the first embodiment shown, the structure of the driving component 110 can be: the driving component 110 includes a driving member 111 and a cam 113 connected to the motor shaft of the driving member 111, the driving member 111 can be a motor, the cam 113 is located between the first driving part 135 and the second driving part 137, and the two sides of the cam 113 are in sliding contact with the first driving part 135 and the second driving part 137 respectively. The cam 113 includes a mounting head 1131 and a cam body 1133. The mounting head 1131 is fixed to the motor shaft of the motor of the driving member 111. The opposite sides of the outer wall of the cam body 1133 are in sliding contact with the first driving part 135 and the second driving part 137 respectively, that is, the first driving part 135 and the second driving part 137 slide along the outer wall of the cam body 1133. Since the cam body 1133 includes at least two long axes and short axes with different lengths, during the rotation of the cam 113, when the first driving part 135 and the second driving part 137 are respectively located on the opposite sides of the short axis, the cam 113 does not move the first driving part 135 and the second driving part 137 outward. When the first driving part 135 and the second driving part 137 are respectively located on opposite sides of the long axis, the cam 113 pushes the first driving part 135 and the second driving part 137 outward in different directions, so that the first clamping part 131 and the second clamping part 133 move toward each other, so that the distance between the first clamping part 131 and the second clamping part 133 is reduced, and the discharge pipe 220 is squeezed, so that the inner wall of the discharge pipe 220 is fitted, so that the channel inside the discharge pipe 220 is closed and the discharge pipe 220 cannot be discharged. Therefore, in the first embodiment, the first clamping member 130a and the second clamping member 130b are driven to move simultaneously by the cam 113, the structure is relatively simple, the number of parts is small, the cost is reduced, and the cam 113 driving is a continuous process, so the action of opening and closing the discharge pipe 220 is more reliable.

[0135] exist Fig.14 In the second embodiment shown, the driving assembly 110 may be provided with two driving members 111, wherein the driving member 111 may be, for example, a cylinder or a motor. In this embodiment, the discharge pipe 220 is clamped by the first clamping member 130a and the second clamping member 130b, so the on-off process of controlling the discharge pipe 220 is more reliable.

[0136] The following content will introduce the solution used in this application to drive a part to move:

[0137] Please refer to Fig.15In the third embodiment of the slurry discharge valve of the present application, the rotation connection between the first clamping member 130a and the second clamping member 130b may be located at one end, the driving assembly 110 may be connected to the first clamping member 130a, and the second clamping member 130b may be fixed to the frame to remain stationary, and the driving assembly 110 drives the first clamping member 130a to move, so that the first clamping part 131 approaches or moves away from the second clamping part 133, thereby squeezing or loosening the discharge pipe 220 to close or open the channel inside the discharge pipe 220. In this embodiment, the driving assembly 110 may use, for example, a motor or a cylinder as a power source.

[0138] Please refer to Fig.16 In the fourth embodiment of the slurry discharge valve of the present application, as a variation of the structure of the third embodiment, a return spring may be provided between the first clamping member 130a and the second clamping member 130b, and the return spring always provides elastic force so that the first clamping portion 131 and the second clamping portion 133 can move away from each other. The driving assembly 110 of this embodiment may adopt, for example, a cylinder. When the discharge pipe 220 is closed, the cylinder is ventilated to drive the first clamping member 130a to move closer to the second clamping member 130b. When the cylinder is not ventilated, the cylinder loses its driving force, and the return spring elastically lifts the first clamping member 130a, thereby opening the discharge pipe 220. In the above content, the slurry discharge valves in the third embodiment and the fourth embodiment have the advantages of simple structure and low cost.

[0139] In some embodiments, the first clamping member 130a and the second clamping member 130b of the present application may also be connected by sliding. Fig.17 In the fifth embodiment of the slurry discharge valve of the present application, the first clamping member 130a is roughly L-shaped, and has a base and a first clamping portion 131 connected to the base. The base can be fixed on the frame, and the first clamping member 130a includes a mounting portion and the second clamping portion 133 connected to the mounting portion. The driving assembly 110 can be a cylinder, wherein the piston rod of the cylinder is connected to the second clamping portion 133 or the mounting portion in the second clamping member 130b; the driving assembly 110 includes a driving motor and a lead screw connected to the driving motor, and the second clamping portion 133 or the mounting portion of the second clamping member 130b is connected to the lead screw. The driving assembly 110 drives the first clamping member 130a to slide along the second clamping member 130b so that the first clamping portion 131 and the second clamping portion 133 can approach or move away from each other to achieve the closing and opening of the discharge pipe 220. Such a design is reliable during the movement, and the distance between the first clamping portion 131 and the second clamping portion 133 is easier to control.

[0140] For further information, please refer to Fig.18In the sixth embodiment of the slurry discharge valve of this example, the driving assembly 110 includes a first electromagnet 110a and a second electromagnet 110b, the first electromagnet 110a is installed on the first clamping part 131, and the second electromagnet 110b is installed on the second clamping part 133. In this embodiment, a slideway can be set on the frame to guide the movement of the first clamping member 130a and the second clamping member 130b. When the magnetic poles of the first electromagnet 110a and the second electromagnet 110b facing each other are the same by changing the direction of the current, the two repel each other, and then the discharge pipe 220 can be loosened to make the channel of the discharge pipe 220 conductive, and when the magnetic poles of the first electromagnet 110a and the second electromagnet 110b facing each other are different, the two attract each other, and then squeeze the discharge pipe 220, so as to close the channel inside the discharge pipe 220. The structure of the slurry discharge valve of this embodiment is relatively simple and the cost is low.

[0141] In addition, an embodiment of the present invention also proposes a slurry discharge valve, which includes a discharge pipe, a clamping assembly and a driving assembly, wherein the driving assembly is connected to the clamping assembly, and the driving assembly is used to drive the clamping assembly to move so as to adjust the inner hole cross-sectional area of ​​the discharge pipe clamped by the clamping assembly. The slurry discharge valve also includes: a memory, a processor, and a control program for the slurry discharge valve stored in the memory and executable on the processor. When the control program of the slurry discharge valve is executed by the processor, the steps of the control method of the slurry discharge valve described in the above embodiments are implemented.

[0142] Optionally, considering that some users have the habit of unplugging the power directly after using the food processor, in order to ensure that the driving component can still drive the clamping component to move when the food processor is powered off, a device for storing electrical energy is provided inside the food processor. Therefore, the discharge valve also includes a power supply (not shown in the figure), which is connected to the driving component. When the food processor where the discharge pipe is located is powered off, the power supply supplies power to the driving component.

[0143] In addition, an embodiment of the present invention further provides a food processor, which includes the pulp discharge valve described in the above embodiments.

[0144] In addition, an embodiment of the present invention further proposes a computer storage medium, on which a control program for a slurry discharge valve is stored. When the control program for the slurry discharge valve is executed by a processor, the steps of the control method for the slurry discharge valve described in the above embodiments are implemented.
