Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a food processor. Background Art

[0002] Existing self-cleaning food processors generally include a main body, a crushing cup installed on the main body, a pulp receiving cup and a waste water box arranged in parallel. A drain valve is provided at the drain outlet of the crushing cup. The drain valve includes a valve core and a pulp nozzle. During the working process, the pulp nozzle needs to rotate within a fan-shaped area formed by aligning with the waste discharge position of the waste water box and the pulp discharge position of the pulp receiving cup. When the pulp nozzle rotates to the in-place position, it needs to stop rotating and the valve core needs to continue to rotate to open the drain port.

[0003] To solve the problem of incomplete cleaning of the drain valve, the prior art sets the pulp nozzle of the drain valve as a detachable structure. For example, the patent with the application number 202120318608.4 discloses a food processor that is easy to clean. The drain pipe is detachably installed at the liquid outlet through the magnetic attraction of a first magnetic part and a second magnetic part, realizing the disassembly and cleaning of the drain pipe. However, this solution has the problems that the installation orientation and position of the drain pipe are unique, and the installation is laborious and difficult. Based on this, the applicant also previously proposed a food processor in which both the cup body and the pulp nozzle are detachable relative to the main body, and the rotating fan-shaped area between the pulp discharge position and the waste discharge position is set as the pulp nozzle placement area. The user can first directly install the pulp nozzle on the main body to make the installation position of the pulp nozzle not unique, then install the cup body after the pulp nozzle is installed, and the valve body and the pulp nozzle cooperate to achieve transmission after the cup body is installed.

[0004] However, during the continuous research process, the applicant found that in the prior art, it is impossible to detect whether the slurry nozzle is installed in place in the structure with multiple installation positions of the slurry nozzle. Since during the use of the food processor, it is necessary to detect the position of the slurry nozzle after the food processor is powered on to see if the slurry nozzle is missing. If the user randomly installs the slurry nozzle in the fan-shaped area, since the detection of the slurry nozzle cannot cover the entire fan-shaped area, a detection blind area of the slurry nozzle is formed between the slurry discharge position and the waste discharge position. When the slurry nozzle is placed at any position between the slurry discharge position and the waste discharge position, that is, when the actual placement position of the slurry nozzle is not clear, it is impossible to detect the slurry nozzle, resulting in abnormal machine alarms and poor overall operation of the machine. The applicant also proposed previously an indirect detection method in which the valve core rotates to drive the slurry discharge nozzle to return to the detectable slurry discharge position or waste discharge position before the crushing program starts after the whole machine is powered on. However, using the valve core to drive the slurry nozzle to rotate to return the slurry discharge nozzle will have problems of detection delay and lag as well as a long standby time. It is easy to cause the valve core of the machine to rotate idly in vain when the user forgets to install the slurry discharge nozzle, resulting in machine abnormalities; and it will also cause the liquid discharge port to be opened during the rotation of the valve core. If the user adds materials to the cavity at this time, there is a risk of material leakage and blockage of the slurry discharge nozzle, and finally the slurry cannot be effectively discharged, resulting in overflow. Based on this, how to reliably detect the position of the slurry nozzle while realizing the multi-position installation of the slurry nozzle has always been a research difficulty for R & D engineers, and the applicant has been conducting continuous research based on this. Summary of the Invention

[0005] The utility model provides a food processor, which is based on a food processor with a detachable slurry nozzle and non-unique slurry nozzle installation positions, solves the problem that the prior art cannot detect the slurry nozzle at multiple installation positions, and further avoids the problems of lag in slurry nozzle detection and leakage of food materials caused by the opening of the liquid discharge port during the detection process.

[0006] The technical solution adopted by the utility model is as follows:

[0007] The utility model provides a food processor, which comprises a main body, a cup body provided with a liquid discharge port, and a liquid discharge valve for controlling the opening and closing of the liquid discharge port. The liquid discharge valve comprises a valve body installed at the liquid discharge port, a valve core rotatably arranged in the valve body, and a slurry nozzle matched with the valve core. The main body is provided with a support platform, the cup body is detachably installed on the support platform, and the support platform is also provided with an installation opening through which the slurry nozzle passes. The upper surface of the support platform is provided with a slurry nozzle placement area located at the edge of the installation opening. The slurry nozzle is detachably installed on the slurry nozzle placement area and is detachably connected to the valve core. The slurry nozzle rotates between a first working position and a second working position along the slurry nozzle placement area. The slurry nozzle is provided with a detection magnet, and the main body is also provided with a detection element for cooperating with the detection magnet to detect the position of the slurry nozzle. A plurality of the detection elements are arranged around the installation opening. The slurry nozzle placement area comprises a detection area corresponding to the detection interval of the detection element and a micro blind area located between two adjacent detection areas. The total rotation angle A of the slurry nozzle along the micro blind area is less than or equal to 10°.

[0008] The food processor provided by the utility model can realize the flexible selection of the cup body by arranging a support platform on the main body, and the cup body is detachably installed above the support platform, which is convenient for replacing different cup bodies to expand various functions of the food processor and achieve diversified functions. In addition, when preparing a drink that is viscous and not easy to discharge from the slurry nozzle, the cup body can be conveniently detached to pour out the prepared drink, with simple operation and avoiding blockage of the valve core and the slurry nozzle, and is convenient for cleaning. While realizing the detachable cup body, a slurry nozzle placement area located at the edge of the installation opening is provided on the upper surface of the support platform, so that the slurry nozzle is detachably installed in the slurry nozzle placement area and detachably connected to the valve core, thereby realizing that the slurry nozzle can be detached relative to the cup body, and at the same time the slurry nozzle can be independently installed on the main body and detached relative to the main body. Therefore, it is convenient to detach and clean the slurry nozzle and deeply clean the outlet position of the valve core when the cup body is detached, realizing the deep cleaning of the drain valve. Specifically, by providing an installation opening through which the slurry nozzle passes, the limit installation of the slurry nozzle is realized. Compared with the prior art in which the slurry nozzle is directly matched with the valve core or the rotating part installed on the cup body, the difficulty of accurately aligning the slurry nozzle with the valve core on the cup body during the installation process is greatly reduced, so that the slurry nozzle can be independently disassembled and assembled on the main body when the cup body is not installed. The support platform forms a slurry nozzle placement area to support the slurry nozzle. The slurry nozzle can be placed at any position on the slurry nozzle placement area and is driven by the valve core to have a slurry discharge position and a waste discharge position. Therefore, the slurry nozzle placement area can provide multiple pre-installation positions between the first working position and the second working position (slurry discharge position and waste discharge position). When the user installs the slurry nozzle, there is no need to accurately position the slurry nozzle to the slurry discharge position. The slurry nozzle can be placed at any pre-installation position other than the slurry discharge position or installed at the waste discharge position, thus eliminating the need for the user to accurately align the position of the slurry nozzle by himself, making the installation of the slurry nozzle by the user more flexible and arbitrary, realizing blind installation of the slurry nozzle, simplifying the assembly, and liberating the user's hands. After the slurry nozzle is placed on the slurry nozzle placement area, it can be driven by the valve core to have a slurry discharge position and a waste discharge position to ensure that during the processing process, the slurry nozzle can smoothly switch between different working positions to realize the functions of slurry discharge and waste discharge;

[0009] On the basis of realizing multi-position installation of the paddle nozzle, a detection magnet is arranged on the paddle nozzle, and the main machine is also provided with a detection element cooperating with the detection magnet to detect the position of the paddle nozzle. A plurality of the detection elements are arranged around the installation port, and the paddle nozzle placement area includes a detection area corresponding to the detection interval of the detection element and a micro-blind area located between two adjacent detection areas. Specifically, the problem that the detection element cannot be arranged around the installation port indefinitely is solved by setting the micro-blind area. The micro-blind area is utilized and the total rotation angle A≤10° of the paddle nozzle along the micro-blind area. According to tests, even if there is a micro-blind area, satisfying 0<A≤10° can increase the probability of the paddle nozzle being placed in the detectable detection area, thereby improving the probability of the paddle nozzle being detected, and realizing direct detection of the paddle nozzle, with a simple detection method and simple program control. The detection element cooperates with the detection magnet. When the paddle nozzle is placed at any position, when the magnet enters the detection area accordingly, the detection element directly detects the position of the paddle nozzle, so that after the machine is powered on, it can directly detect whether the paddle nozzle is placed on the paddle nozzle placement area. The position detection of the paddle nozzle is reliable, and the detection of the paddle nozzle does not need to rely on the rotation of the valve core to drive the paddle nozzle back to its original position, thereby effectively preventing the paddle nozzle from being missed and causing the valve core to rotate idly, and the user's missed installation of the paddle nozzle causing the paddle nozzle detection to be delayed. Before entering the paddle making program, the valve core does not rotate at all to perform the paddle nozzle detection. Since the valve core does not need to move, the valve core does not rotate to minimize the leakage of food and blockage of the drain port caused by the rotation of the valve core in the standby state, which is convenient for user operation.

[0010] In a preferred embodiment, the paddle nozzle and the valve core are attracted to each other through a magnetic attraction component, and the magnetic attraction component is used to effectively attract the paddle nozzle and the valve core and rotate from the micro blind area to the detection area when the cup body is placed on the supporting platform.

[0011] By setting up a magnetic attraction component, the paddle nozzle and the valve core are attracted to each other through the magnetic attraction component, and the magnetic attraction component is used to make the paddle nozzle and the valve core effectively attracted to each other and rotate from the micro blind area to the detection area when the cup body is placed on the supporting platform, so as to realize the position correction of the paddle nozzle. Therefore, even if the user installs the paddle nozzle in the micro blind area, during the process of the user installing the cup body, the paddle nozzle can be automatically rotated and straightened to enter the detectable detection area through the cooperation of the magnetic attraction component, so as to better detect whether the paddle nozzle is placed.

[0012] More preferably, the magnetic attraction component includes a plurality of first magnets arranged in the valve body and a plurality of second magnets arranged on the pulp nozzle, the plurality of first magnets are arranged at intervals along the circumference of the valve body, the magnetic poles of at least two of the first magnets are arranged in opposite directions, and the second magnets are attracted to the first magnets one by one.

[0013] By arranging a plurality of first magnets and a plurality of second magnets, the plurality of first magnets are arranged at intervals along the circumferential direction of the valve body, thereby improving the circumferential suction reliability between the slurry nozzle and the valve core. The magnetic poles of at least two first magnets are arranged in opposite directions, that is, the suction directions between different groups of first magnets and second magnets are unique. During the suction process between the slurry nozzle and the valve core, the slurry nozzle will automatically adjust to the angle of reliable suction, realizing the automatic adjustment of the position of the slurry nozzle from the micro-blind area to the detection area, thereby increasing the probability of the slurry nozzle being detected and realizing the reliable detection of the position of the slurry nozzle.

[0014] More preferably, the drain valve further includes a clutch mechanism. The clutch mechanism includes an upper clutch structure driven by the valve core and a lower clutch structure for driving the slurry nozzle to move synchronously. The lower clutch structure is linked or rotates relative to the upper clutch structure, and the magnetic attraction assembly is arranged between the slurry nozzle and the lower clutch structure.

[0015] By arranging the clutch mechanism and through the switching cooperation between the combined linkage state and the relative rotation state between the upper clutch structure and the lower clutch structure, the slurry nozzle and the valve core can be detachably connected, and at the same time, the slurry nozzle and the valve core can realize the state switching of linkage and relative rotation. Since the lower clutch structure can be linked with the upper clutch structure to drive the slurry nozzle to rotate, the valve core drives the slurry nozzle to rotate. The lower clutch structure can rotate relative to the upper clutch structure. Therefore, when the slurry nozzle is driven by the valve core to rotate to the first working position or the second working position, that is, the slurry discharge position or the waste discharge position, then the lower clutch structure and the upper clutch structure are changed to a separated and relatively rotating state, so that the slurry nozzle remains in the working position and the valve core continues to rotate to realize the switching of the drain port to the open state. Generally, the valve core remains closed during the process of driving the slurry nozzle to rotate. When the slurry nozzle rotates in place, the valve core continues to rotate to the open position. While realizing the flexible disassembly of the slurry nozzle and the valve core, ensuring the reliable linkage cooperation after the slurry nozzle and the valve core are installed in place, enabling the slurry nozzle to smoothly switch the working position to realize the corresponding functions, and the structure is reliable. The magnetic attraction assembly is arranged between the slurry nozzle and the lower clutch structure to enable the slurry nozzle and the lower clutch structure to be reliably attracted, so that with the rotation or stop of the lower clutch structure, the normal slurry discharge or waste discharge work can be realized.

[0016] In a preferred embodiment, the detection element includes a first detection element for cooperating with the magnet to detect whether the slurry nozzle is in the first working position, a second detection element for cooperating with the magnet to detect whether the slurry nozzle is in the second working position, and a third detection element located between the first detection element and the second detection element. At least two of the first detection element, the second detection element, and the third detection element have non-overlapping detection intervals.

[0017] The detection components include a first detection component, a second detection component, and a third detection component. At the same time, the first detection component and the second detection component respectively detect the first working position and the second working position of the nozzle, so that when the nozzle reaches the first working position, it can be detected to reliably discharge the slurry, and when it reaches the second working position, it can be detected to reliably discharge the waste. The third detection component is located between the first detection component and the second detection component, adding a new detection area, thereby correspondingly reducing the detection blind area formed between the first detection component and the second detection component, forming a micro-blind area with a reduced angle, and reducing the probability that the nozzle cannot be detected. The detection intervals of at least two of the first detection component, the second detection component, and the third detection component do not overlap, so as to reduce the micro-blind area while avoiding waste of the number of detection components and solving the problem that the detection components cannot be arranged infinitely along the installation opening due to their own volume, etc., so that an appropriate number of detection components can be installed in a limited space to realize nozzle detection.

[0018] In a preferred embodiment, the rotation angle B of the nozzle between the first working position and the second working position satisfies 85° ≤ B ≤ 90°, and the rotation angle C of the nozzle along the detection area corresponding to a single detection component satisfies 20° ≤ C ≤ 27°.

[0019] By setting the rotation angle B of the nozzle between the first working position and the second working position within 85° - 90°, the fan-shaped area formed by the corresponding nozzle placement area is within 85° - 90°, with a reasonable size, enabling the user to have enough choices for nozzle placement positions, realizing flexible placement of the nozzle. At the same time, the rotation angle of the nozzle between the two working positions is not too far, avoiding an increase in the probability of dripping of the temporarily stored liquid droplets during the rotation of the nozzle. It avoids the problem that when B < 85°, the nozzle placement area is too small, the placement is not flexible, and it is not convenient for the user to operate. At the same time, it avoids the problem that the angle between the first working position and the second working position is too small, resulting in difficulties in placing the corresponding slurry receiving cup and waste water box, and limited volume. In addition, it avoids the risk that the liquid droplets temporarily stored in the nozzle may drip during the rotation of the nozzle when B > 90°.

[0020] Furthermore, the rotation angle C of the nozzle along the detection area corresponding to a single detection component satisfies 20° ≤ C ≤ 27°. Therefore, the detection area corresponding to a single detection component can occupy nearly 1 / 3 of the nozzle placement area, so that the purpose of reducing the micro-blind area can be achieved by using 2 or 3 detection components, and the number and position layout of the detection components are more reasonable.

[0021] In a preferred embodiment, the valve core rotates 360° and has a closed position and an open position. The rotation angle D of the valve core from the closed position to the open position satisfies 150° ≤ D ≤ 180°, and the rotation angle B of the nozzle between the first working position and the second working position satisfies 85° ≤ B ≤ 90°.

[0022] By setting the rotation angle D of the valve core between the closed position and the open position to be 150° - 180°, and the rotation angle of the slurry nozzle between the first working position and the second working position to be B, satisfying 85° ≤ B ≤ 90°, that is, the state switching angle of the valve core is much larger than and covers the position switching angle of the slurry nozzle, so as to ensure that during the process of the valve core rotating from the closed position to the open position, it is ensured that the slurry nozzle has already rotated to the corresponding working position in advance. This can not only avoid liquid drainage during the rotation of the slurry nozzle, causing the liquid to spill out, but also avoid the risk of liquid leakage when the valve core is opened during the rotation of the slurry nozzle.

[0023] In a preferred embodiment, the total rotation angle A of the slurry nozzle along the micro-blind area and the rotation angle B of the slurry nozzle between the first working position and the second working position satisfy A / B ≤ 13%.

[0024] By the total rotation angle A of the slurry nozzle along the micro-blind area and the rotation angle B of the slurry nozzle between the first working position and the second working position satisfying A / B ≤ 13%, it effectively avoids the situation that the micro-blind area is too large to cause the slurry nozzle to be not reliably detected, can increase the probability that the user places the slurry nozzle in the detectable area, and realizes the reliable detection of the slurry nozzle.

[0025] In a preferred embodiment, the total rotation angle A of the slurry nozzle along the micro-blind area satisfies 4° ≤ A ≤ 9°.

[0026] By setting the total rotation angle A of the slurry nozzle along the micro-blind area to satisfy 4° ≤ A ≤ 9°, on the premise of controlling the number of detection elements for the convenience of installation of the detection elements, the micro-blind area can be further reduced, thereby further reducing the probability that the user places the slurry nozzle in the micro-blind area. The user can place the slurry nozzle in the detection area by means of the automatic suction of the slurry nozzle or the limiting structure in the slurry nozzle placement area, etc., to realize the position detection of the slurry nozzle.

[0027] In a preferred embodiment, the slurry nozzle includes a slurry discharge pipe and a seat body fixed at the inlet end of the slurry discharge pipe. The seat body is provided with a protruding portion extending radially outward, and the detection magnet is arranged in the protruding portion.

[0028] By setting the slurry nozzle to include a slurry discharge pipe and a seat body fixed at the inlet end of the slurry discharge pipe, the seat body is used to support the whole by placing it in the slurry nozzle placement area, which is convenient for taking the slurry nozzle. The slurry discharge pipe is used to communicate and cooperate with the valve core to achieve liquid discharge. The protruding portion is provided on the seat body, which is convenient for the user to take and can also be used to guide the user to install the slurry nozzle, guiding the user to reliably place the slurry nozzle on the detection area to realize the reliable detection of the slurry nozzle. At the same time, the detection magnet is arranged in the protruding portion, and the structure and installation are simplified.

[0029] In a preferred embodiment, the main body is provided with a limiting rib that cooperates with the protruding portion in a stop manner, and the limiting rib and the protruding portion cooperate to limit the slurry nozzle in the first working position or the second working position.

[0030] By providing a limiting rib on the main body that cooperates with the protruding portion in a stop manner, and utilizing the cooperation between the protruding portion and the limiting rib, the slurry nozzle can be limited to rotate between the first working position and the second working position. On the basis of ensuring that the slurry nozzle can flexibly switch the working position, the movement trajectory of the slurry nozzle is restricted, and at the same time, the interval where the user places the slurry nozzle is restricted, so that the slurry nozzle can be disassembled and can be reliably installed and detected; at the same time, the mutual cooperation between the limiting rib and the protruding portion plays a guiding role during the process of the user installing the slurry nozzle, and it is easier for the user to place the slurry nozzle on a reasonable and detectable detection area to achieve the purpose of detecting the position of the slurry nozzle.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0046] As Figure 1-7 shown, in one embodiment, the present utility model provides a food processor, which includes a main body 10, a cup body 20 provided with a liquid discharge port 21, and a liquid discharge valve 30 for controlling the opening and closing of the liquid discharge port 21. The liquid discharge valve 30 includes a valve body 31 installed at the liquid discharge port 21, a valve core 32 rotatably arranged in the valve body 31, and a nozzle 33 cooperating with the valve core 32. The main body 10 is provided with a support platform 11, the cup body 20 is detachably installed on the support platform 11, and an installation opening 12 for the nozzle 33 to pass through is also provided through the support platform 11. A nozzle placement area 13 located at the edge of the installation opening 12 is provided on the upper surface of the support platform 11. The nozzle 33 is detachably installed on the nozzle placement area 13 and is detachably connected to the valve core 32. The nozzle 33 rotates between a first working position and a second working position along the nozzle placement area 13. The nozzle 33 is provided with a detection magnet 50, and the main body 10 is also provided with a detection element for cooperating with the detection magnet 50 to detect the position of the nozzle 33. A plurality of detection elements are arranged around the installation opening 12. The nozzle placement area 13 includes a detection area corresponding to the detection interval of the detection element and a micro blind area located between two adjacent detection areas. The total rotation angle A of the nozzle 33 along the micro blind area is ≤ 10°.

[0047] Preferably, the food processor further includes a crushing knife 64 arranged in the cup body 20, a motor 63 for driving the crushing knife, a juice receiving cup 61, and a waste water box 62. The nozzle 33 discharges pulp when it is in the first working position and is aligned with the juice receiving cup 61, and is used to discharge cleaning waste water when it is in the second working position and is aligned with the waste water box 62.

[0048] Optionally, the detection element is a Hall element. Of course, the detection element can also be a reed switch.

[0049] The food processor provided by the present utility model can flexibly select the cup body 20 by arranging a support platform 11 on the main body 10, and the cup body 20 is detachably installed above the support platform 11. This facilitates the replacement of different cup bodies 20 to expand the various functions of the food processor and achieve diversified functions. In addition, when preparing a viscous drink that is not easy to discharge from the slurry nozzle 33, the cup body 20 can be conveniently detached to pour out the prepared drink. The operation is simple and it can avoid clogging of the valve core 32 and the slurry nozzle 33, which is convenient for cleaning. While realizing the detachable cup body 20, a slurry nozzle placement area 13 is provided on the upper surface of the support platform 11 at the edge of the installation opening 12, so that the slurry nozzle 33 is detachably installed in the slurry nozzle placement area 13 and is detachably connected to the valve core 32. Thus, the slurry nozzle 33 can be detached relative to the cup body 20, and at the same time, the slurry nozzle 33 can be independently installed on the main body 10 and detached relative to the main body 10. Therefore, it is convenient to detach and clean the slurry nozzle 33 and deeply clean the outlet position of the valve core 32 when the cup body 20 is detached, realizing the deep cleaning of the drain valve 30. Specifically, by arranging an installation opening 12 through which the slurry nozzle 33 passes, the limit installation of the slurry nozzle 33 is realized. Compared with the prior art in which the slurry nozzle 33 is directly matched with the valve core 32 or the rotating part installed on the cup body 20, the difficulty of accurately aligning the slurry nozzle 33 with the valve core 32 on the cup body 20 during the installation process is greatly reduced. The slurry nozzle 33 can be independently disassembled and assembled on the main body 10 when the cup body 20 is not installed. The support platform 11 forms a slurry nozzle placement area 13 to support the slurry nozzle 33. The slurry nozzle 33 can be placed at any position on the slurry nozzle placement area 13 and is driven by the valve core 32 to have a slurry discharge position and a waste discharge position. Therefore, the slurry nozzle placement area 13 can provide multiple pre-installation positions between the first working position and the second working position (slurry discharge position and waste discharge position). When the user installs the slurry nozzle 33, there is no need to accurately position the slurry nozzle 33 at the slurry discharge position. The slurry nozzle 33 can be placed at any pre-installation position other than the slurry discharge position, or installed at the waste discharge position. Thus, the user is saved from independently and accurately aligning the position of the slurry nozzle 33, making the installation of the slurry nozzle 33 more flexible and casual, realizing the blind installation of the slurry nozzle 33, simplifying the assembly, and liberating the user's hands. After the slurry nozzle 33 is placed on the slurry nozzle placement area 13, it can be driven by the valve core 32 to have a slurry discharge position and a waste discharge position to ensure that during the processing, the slurry nozzle 33 can smoothly switch between different working positions to realize the slurry discharge and waste discharge functions;

[0050] On the basis of realizing the multi-position installation of the slurry nozzle 33, by providing a detection magnet 50 on the slurry nozzle 33, the main machine 10 is also provided with a detection element that cooperates with the detection magnet 50 to detect the position of the slurry nozzle 33. A plurality of detection elements are arranged around the installation port 12. The slurry nozzle placement area 13 includes a detection area corresponding to the detection range of the detection element and a micro blind area located between two adjacent detection areas. Specifically, by setting the micro blind area, the problem that the detection element cannot be arranged around the installation port 12 without limit due to its certain volume is solved. Using the micro blind area and the total rotation angle A of the slurry nozzle 33 along the micro blind area satisfies 0 < A ≤ 10°. According to tests, even if there is a micro blind area, satisfying 0 < A ≤ 10° can increase the probability that the slurry nozzle 33 is placed in the detectable detection area, thereby increasing the probability of detecting the slurry nozzle 33 and realizing the direct detection of the slurry nozzle 33. The detection element cooperates with the detection magnet 50. After the slurry nozzle 33 is placed at any position, when the magnet enters the detection area correspondingly, the detection element directly detects the position where the slurry nozzle 33 is located. So that after the machine is powered on, it can directly detect whether the slurry nozzle 33 is placed on the slurry nozzle placement area 13. The detection of the slurry nozzle 33 does not need to be realized by driving the slurry nozzle 33 to return to its position by rotating the valve core 32. Thus, it effectively prevents the valve core 32 from idling due to the missing installation of the slurry nozzle 33, and the situation that the detection of the slurry nozzle 33 is delayed due to the user's missing installation of the slurry nozzle 33. Before entering the pulping program, the valve core 32 does not rotate at all for the detection of the slurry nozzle 33. Since the valve core 32 does not need to act, it minimizes the leakage of food materials and the blockage of the drainage port 21 caused by the rotation of the valve core 32 due to user operation in the standby state, which is convenient for the user's operation.

[0051] In a preferred embodiment, the slurry nozzle 33 and the valve core 32 are attracted and combined through a magnetic attraction assembly. The magnetic attraction assembly is used to effectively attract and combine the slurry nozzle 33 and the valve core 32 and rotate from the micro blind area to the detection area during the process of placing the cup body 20 on the support platform 11.

[0052] More preferably, as Figure 7 shown, the magnetic attraction assembly includes a plurality of first magnets 71 arranged in the valve body 31 and a plurality of second magnets 72 arranged on the slurry nozzle 33. The plurality of first magnets 71 are arranged at intervals along the circumferential direction of the valve body 31. The magnetic poles of at least two first magnets 71 are arranged in opposite directions. The second magnets 72 are attracted and combined with the first magnets 71 one by one. More preferably, the drain valve 30 further includes a clutch mechanism. The clutch mechanism includes an upper clutch structure 321 driven by the valve core 32 and a lower clutch structure 322 for driving the slurry nozzle 33 to move synchronously. The lower clutch structure 321 and the upper clutch structure 322 are linked or rotated relative to each other. The magnetic attraction assembly is arranged between the slurry nozzle 33 and the lower clutch structure. That is, in this embodiment, the first magnets 71 and the second magnets 72 are respectively arranged on the lower clutch structure 322 and the slurry nozzle 33.

[0053] By setting up a magnetic attraction component, the paddle nozzle 33 and the valve core 32 are attracted to each other through the magnetic attraction component, and the magnetic attraction component is used to make the paddle nozzle 33 and the valve core 32 effectively attracted to each other and rotated from the micro blind area to the detection area during the process of placing the cup body 20 on the support platform 11, so as to realize the position correction of the paddle nozzle 33. Therefore, even if the user installs the paddle nozzle 33 in the micro blind area, during the process of the user installing the cup body 20, the paddle nozzle 33 can be automatically rotated and straightened to enter the detectable detection area through the cooperation of the magnetic attraction component, so as to better detect whether the paddle nozzle 33 is placed.

[0054] By providing a plurality of first magnets and a plurality of second magnets, the plurality of first magnets are arranged at intervals along the circumference of the valve body 31, thereby improving the circumferential attraction reliability of the paddle nozzle 33 and the valve core 32, and the magnetic poles of at least two first magnets are arranged in opposite directions, that is, the attraction orientations of the first magnets and the second magnets of different groups are unique, and the paddle nozzle 33 will automatically adjust to a reliable attraction angle during the attraction process with the valve core 32, thereby realizing automatic adjustment of the position of the paddle nozzle 33 from the micro blind area to the detection area, thereby increasing the probability of the paddle nozzle 33 being detected and realizing reliable detection of the position of the paddle nozzle 33.

[0055] By setting a clutch mechanism, the upper clutch structure and the lower clutch structure are combined with the linkage state and the relative rotation state switching, so that the paddle nozzle 33 and the valve core 32 can be detachably connected, and the paddle nozzle 33 and the valve core 32 can realize the linkage and relative rotation state switching. Since the lower clutch structure can be linked with the upper clutch structure to drive the paddle nozzle 33 to rotate, so that the valve core 32 drives the paddle nozzle 33 to rotate, and the lower clutch structure can rotate relative to the upper clutch structure, therefore, when the paddle nozzle 33 is driven by the valve core 32 to rotate to the first working position or the second working position, that is, the pulp discharge position or the waste discharge position, then, the lower clutch structure and the upper clutch structure are changed to a separated and relatively rotating state, so that the paddle nozzle 33 remains in the working position and the valve core 32 continues to rotate, and the liquid discharge port 21 is switched to an open state. Usually, the valve core 32 keeps closed during the process of driving the paddle nozzle 33 to rotate, and when the paddle nozzle 33 rotates to the right position, the valve core 32 continues to rotate to open. While realizing flexible disassembly of the slurry nozzle 33 and the valve core 32, the reliable linkage and cooperation between the slurry nozzle 33 and the valve core 32 after being installed in place is ensured, so that the slurry nozzle 33 can smoothly switch the working position to realize the corresponding function, and the structure is reliable. The magnetic attraction component is arranged between the slurry nozzle 33 and the lower clutch structure, so that the slurry nozzle 33 and the lower clutch structure can be reliably attracted, so that as the lower clutch structure can rotate or stop rotating, normal slurry discharge or waste discharge can be realized.

[0056] Of course, the specific structure of the magnetic attraction component is not limited to the above one. For example, the magnet component includes a ring-shaped first magnet and a ring-shaped second magnet. By arranging multiple magnetic poles along the circumferential direction of the first magnet and setting the adjacent magnetic poles to face in different directions, the first magnet and the second magnet can still be rotationally attracted to correct the position of the nozzle 33 during the attraction process of the first magnet and the second magnet.

[0057] In addition, the present utility model does not limit the structure of the nozzle 33. For example, Figure 7 As shown, the nozzle 33 includes a slurry discharge pipe 331 and a seat body 332 fixed at the inlet end of the slurry discharge pipe. The seat body is provided with a protruding portion 333 extending radially outward, and the detection magnet 50 is arranged in the protruding portion 333. More preferably, the main machine 10 is provided with a limiting rib 14 that abuts and cooperates with the protruding portion. The limiting rib 14 abuts against the protruding portion to limit the nozzle 33 at the first working position or the second working position.

[0058] Optionally, the limiting rib protrudes above the support platform 11 to abut and limit with the protruding portion. Of course, in other embodiments, optionally, a limiting structure is arranged below the support platform 11, and the limiting structure abuts and cooperates with the slurry discharge pipe to limit the nozzle 33 at the first working position or the second working position.

[0059] By setting the nozzle 33 to include a slurry discharge pipe and a seat body fixed at the inlet end of the slurry discharge pipe, the seat body is used to support the whole by placing it in the nozzle placement area 13, which is convenient for taking and placing the nozzle 33. The slurry discharge pipe is communicated and cooperated with the valve core 32 to achieve liquid discharge. The protruding portion is arranged on the seat body, which is convenient for the user to take and place, and can also be used to guide the user to install the nozzle 33, guiding the user to reliably place the nozzle 33 on the detection area to realize reliable detection of the nozzle 33. At the same time, the detection magnet 50 is arranged in the protruding portion, and the structure and installation are simplified.

[0060] By arranging a limiting rib on the main machine 10 that abuts and cooperates with the protruding portion, through the cooperation of the protruding portion and the limiting rib, the nozzle 33 can be limited to rotate between the first working position and the second working position. On the basis of ensuring the flexible switching of the working position of the nozzle 33, the movement track of the nozzle 33 is restricted, and at the same time, the interval for the user to place the nozzle 33 is restricted, so that the nozzle 33 can be disassembled and reliably installed and detected. At the same time, the mutual cooperation of the limiting rib and the protruding portion plays a guiding role during the process of the user installing the nozzle 33, and it is easier for the user to place the nozzle 33 on a reasonable and detectable detection area to achieve the purpose of detecting the position of the nozzle 33.

[0061] It should be noted that the present utility model does not limit the specific number of detection elements provided. For example:

[0062] Embodiment 1, such as Figure 1-7As shown, there is one detection magnet 50 and three detection elements 40. Among them, all three detection elements can cooperate with the detection magnet 50 to detect the position of the slurry nozzle 33.

[0063] Specifically, as Figure 3 、 4 shown, the detection element 40 includes a first detection element 41 for cooperating with the magnet to detect whether the slurry nozzle 33 is in the first working position, a second detection element 42 for cooperating with the magnet to detect whether the slurry nozzle 33 is in the second working position, and a third detection element 43 located between the first detection element 41 and the second detection element 42. The detection ranges of at least two of the first detection element 41, the second detection element 42, and the third detection element 43 do not overlap. As Figure 4 shown, the detection areas corresponding to the first detection element 41, the second detection element 42, and the third detection element 43 are the first detection area P1, the second detection area P2, and the third detection area P3. In this embodiment, the micro-blind area is divided into two, namely the first micro-blind area P4 between the first detection area P1 and the third detection area P3 and the second micro-blind area P5 between the second detection area P2 and the third detection area P3.

[0064] Combined with Figure 3 and Figure 4 , in this embodiment, preferably, the slurry nozzle 33 and the valve core 32 are attracted and combined by a magnetic attraction assembly. The magnetic attraction assembly is used to effectively attract and combine the slurry nozzle 33 and the valve core 32 and rotate from the micro-blind area to the detection area during the process of placing the cup body 20 on the support platform 11.

[0065] Combined with the arrangement of the detection elements in this embodiment, the detection principle of the slurry nozzle is described: Combined with Figure 4 , for example, when the user accidentally places the slurry nozzle in the first micro-blind area P4, due to the setting of the magnetic attraction assembly, when the user installs the cup body, the slurry nozzle will automatically rotate in the direction of attracting and combining with the valve core, so as to rotate from the first micro-blind area P4 to the first detection area P1. After the whole machine is powered on, the slurry nozzle is in the detection area and the position of the slurry nozzle can be detected.

[0066] In this embodiment, the detection elements include a first detection element 41, a second detection element 42, and a third detection element 43. At the same time, the first detection element 41 and the second detection element 42 respectively detect the first working position and the second working position of the nozzle 33, so that when the nozzle 33 reaches the first working position, it can be detected to reliably perform the pulp discharging operation, and when it reaches the second working position, it can be detected to reliably perform the waste discharging operation. The third detection element 43 is located between the first detection element 41 and the second detection element 42, adding a new detection area, thereby correspondingly reducing the detection blind area formed between the first detection element 41 and the second detection element 42, forming a micro blind area with a reduced angle, and reducing the probability that the nozzle 33 cannot be detected. The detection intervals of at least two of the first detection element 41, the second detection element 42, and the third detection element 43 do not overlap, so as to reduce the micro blind area while avoiding waste of the number of detection elements, and enabling the installation of an appropriate number of detection elements in a limited space to realize the detection of the nozzle 33.

[0067] In fact, the arrangement of the detection elements and the detection magnet 50 is not limited to the above one. In other embodiments, the number of detection elements can be optionally set to 2 or 4. One detection magnet 50 can be set, or multiple detection magnets 50 can be set at corresponding different positions. Through the cooperation of multiple detection magnets 50 with the corresponding detection elements, double detection is realized to improve the accuracy of the detection position of the nozzle 33.

[0068] Of course, it should be noted that the setting of the detection area and the micro blind area in the present utility model is not limited to the above one. For example:

[0069] Embodiment 2. The similarity between this embodiment and Embodiment 1 is that 3 detection elements are used. The difference is that, compared with Embodiment 1, in this embodiment, by appropriately expanding the detection intervals of two of the detection elements, the detection areas corresponding to the two detection elements with the expanded intervals are set to be adjacent (or overlapping), so as to reduce the size of the micro blind area. For example, referring to Embodiment 1 Figure 4 , by expanding the detection intervals of the first detection element and / or the second detection element, P1 and P3 are made adjacent or overlapping, and there is no micro blind area P4, only a micro blind area P5 is formed.

[0070] Embodiment Example 3, different from Embodiment Example 1, in this embodiment example, the third detection element is omitted, and only two detection elements are provided, namely the above-mentioned first detection element and second detection element. By setting the rotation angle B of the nozzle 33 between the first working position and the second working position and the detection angles of the first detection element and the second detection element, a micro blind area P6 is formed between the first detection area P1 corresponding to the first detection element and the second detection area P2 corresponding to the second detection element. Among them, the rotation angle of the nozzle in the micro blind area P6 is A, and 0 < A ≤ 10°; specifically, in this embodiment example, the rotation angle B of the nozzle 33 between the first working position and the second working position is reduced compared to Embodiment Example 1, for example, 70° ≤ B ≤ 80°.

[0071] In a preferred embodiment, for example, in Embodiment Example 1, as Figure 3 、 4 shown, the rotation angle of the nozzle 33 between the first working position and the second working position is B, satisfying 85° ≤ B ≤ 90°, and the rotation angle C of the nozzle 33 along the detection area corresponding to a single detection element satisfies 20° ≤ C ≤ 27°.

[0072] By setting the rotation angle B of the nozzle 33 between the first working position and the second working position within 85° - 90°, the fan-shaped area formed by the corresponding nozzle placement area 13 is within 85° - 90°, with a reasonable size, enabling the user to have sufficient choices for the placement positions of the nozzle 33, realizing the flexible placement of the nozzle 33. At the same time, it also ensures that the rotation angle of the nozzle 33 between the two working positions is not too far, preventing the probability of the temporarily stored liquid droplets dripping during the rotation of the nozzle 33 from increasing. It avoids the situation where when B < 85°, the nozzle placement area 13 is too small, making the placement inflexible and inconvenient for the user to operate. At the same time, it avoids the situation where the angle between the first working position and the second working position is too small, causing the corresponding slurry receiving cup and the waste water box to be unable to be placed properly and having limited volume; in addition, it avoids the risks such as the liquid droplets temporarily stored inside the nozzle 33 may drip during the rotation of the nozzle 33 when B > 90°. Further, the rotation angle C of the nozzle 33 along the detection area corresponding to a single detection element satisfies 20° ≤ C ≤ 27°. Therefore, the detection area corresponding to a single detection element can occupy nearly 1 / 3 of the nozzle placement area 13, so that the purpose of reducing the micro blind area can be achieved by using 2 or 3 detection elements, and the quantity and position layout of the detection elements are more reasonable.

[0073] In a preferred embodiment, for example, in Embodiment Example 1, the valve core rotates 360° and has a closed position and an open position. As Figure 5 shows the state where the valve core is in the closed position. As Figure 6It shows the state where the valve core is in the open position. The rotation angle D of the valve core 32 from the closed position to the open position satisfies 150° ≤ D ≤ 180°. The rotation angle B of the slurry nozzle 33 between the first working position and the second working position satisfies 85° ≤ B ≤ 90°.

[0074] By setting the rotation angle D of the valve core 32 between the closed position and the open position within 150° - 180°, and the rotation angle B of the slurry nozzle 33 between the first working position and the second working position satisfies 85° ≤ B ≤ 90°, that is, the state switching angle of the valve core 32 is much larger than and covers the position switching angle of the slurry nozzle 33. Thus, during the process of the valve core 32 rotating from the closed position to the open position, it is ensured that the slurry nozzle 33 has already rotated to the corresponding working position in advance, which can not only avoid liquid drainage during the rotation of the slurry nozzle 33 and prevent liquid from spilling, but also avoid the risk of liquid leakage when the valve core 32 opens during the rotation of the slurry nozzle 33.

[0075] In a preferred embodiment, the total rotation angle A of the slurry nozzle 33 along the micro-blind area satisfies 4° ≤ A ≤ 9°.

[0076] By setting the total rotation angle A of the slurry nozzle 33 along the micro-blind area to satisfy 4° ≤ A ≤ 9°, on the premise of controlling the number of detection elements for easy installation of the detection elements, the micro-blind area can be further reduced, thereby further reducing the probability that the user places the slurry nozzle 33 in the micro-blind area. The user can place the slurry nozzle 33 in the detection area by means of the automatic suction of the slurry nozzle 33 or the limiting structure of the slurry nozzle placement area 13, etc., to realize the position detection of the slurry nozzle 33.

[0077] In a preferred embodiment, the total rotation angle A of the slurry nozzle 33 along the micro-blind area and the rotation angle B of the slurry nozzle 33 between the first working position and the second working position satisfy A / B ≤ 13%. For example, in other embodiments, 85° ≤ B ≤ 120°, 0 < A ≤ 10°, and A / B ≤ 13%.

[0078] Specifically: A = 10°, 9°, 8°, 7°, 6°, 5°, 4°, 3° or 2°, etc.; B = 90°, 100° or 110°, etc.

[0079] By the total rotation angle A of the slurry nozzle 33 along the micro-blind area and the rotation angle B of the slurry nozzle 33 between the first working position and the second working position satisfying A / B ≤ 13%, it effectively avoids the situation that the micro-blind area is too large to reliably detect the slurry nozzle 33, and can increase the probability that the user places the slurry nozzle 33 in the detectable area, realizing the reliable detection of the slurry nozzle 33.

[0081] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other, and the differences between each embodiment and other embodiments are emphasized.

[0082] The above are only the embodiments of the present invention and are not intended to limit the present invention.
