In addition, in the present embodiment, the driven assembly 7 is driven by the first driving device 51, and the driven assembly 7 includes a driven gear 72 and an intermediate gear 71 engaged with the driven gear 72, the first driving device 51 drives the intermediate gear 71 to rotate, and the liquid discharge pipe 2 is integrally formed with the driven gear 72 and is driven to rotate by the driven gear 72.
In this embodiment, the first driving device 51 and the second driving device 52 are integrally formed and are driven by the same motor 50 to operate, wherein the first driving device 51 is a first incomplete gear, the second driving device 52 is a second incomplete gear, the first incomplete gear drives the driven component 7 to rotate, the second incomplete gear drives the planar movable valve plate 81 to rotate, because the first incomplete gear is provided with an incomplete first driving tooth 511, the second incomplete gear is provided with an incomplete second driving tooth 521, and the first driving tooth 511 and the second driving tooth 521 are arranged in a vertically staggered manner, the driven component 7 and the planar movable valve plate 81 rotate asynchronously, when the discharge pipe 2 rotates, the planar movable valve plate 81 does not rotate, and when the planar movable valve plate 81 rotates, the discharge pipe 2 does not rotate. Therefore, after the liquid discharge pipe 2 rotates to a preset position above the pulp receiving cup or above the waste water box, the plane movable valve plate 81 rotates to enable the communicating hole 80 to be communicated with the static valve hole 84, the pulp discharging operation of the liquid discharge pipe 2 above the pulp receiving cup is achieved, and the waste water discharging operation of the waste water box is achieved.
In addition, in this embodiment, the driven assembly 7, the upper and lower static valve plates, the planar dynamic valve plate 81, the first driving device 51, and the second driving device 52 are all disposed in the mounting housing 85, the rear end of the discharge pipe 2 is connected with the driven gear 72 integrally by extending into the mounting housing 52, wherein the mounting housing 85 is further disposed with the sensing plate 9, the sensing plate 9 is disposed with the second sensing body 92, the planar dynamic valve plate 81 is disposed with the first sensing body 91, the first sensing body 91 is electrically connected with the second sensing body 92, when the planar dynamic valve plate 81 moves to the position where the first sensing body 91 is aligned with the second sensing body 92, the sensing plate 9 detects that the communication hole 80 coincides with the static valve hole 84, and meanwhile, the food processor is further disposed with a control device (not shown), the control device is electrically connected with the sensing plate 9 and the motor 50, when the sensing plate 9 detects a signal, the signal is transmitted to the control device, the control device controls the motor to stop rotating, when the plane movable valve plate 81 rotates to the communicating hole 80 to be communicated with the static valve hole 84, the plane movable valve plate 81 stops rotating, and at the moment, the liquid discharge pipe 2 can continuously perform liquid discharge operation. For this embodiment, the first inductor is a magnet, the second inductor is a hall element, and in this embodiment, the induction plate is provided with two hall elements for respectively sensing the liquid discharge position and the valve hole closing position. In the drain valve assembly previously applied by the applicant, three hall elements are required to be arranged on the sensing plate, and the hall elements are respectively used for sensing the slurry discharging position, the waste water discharging position and the static valve hole closing position.
Meanwhile, in this embodiment, the first incomplete gear is further provided with an arc portion 512 which is vertically staggered relative to the first driving tooth 511, the intermediate gear 71 is provided with a driven tooth 711 and a rotation stopping rib 712, and after the first driving tooth 511 and the driven tooth 711 are completely meshed, the rotation stopping rib 712 and the arc portion 512 cooperate to form a rotation stopping structure of the driven component 7. Because the rotation stopping rib and the arc part form a rotation stopping structure, the driven component still cannot actively rotate if external force is applied to rotate the liquid discharge pipe, so that the phenomenon that the liquid discharge pipe is artificially rotated by mistake in the liquid discharge process is effectively avoided, and the risk of scalding of consumers is avoided. Certainly, in this embodiment, there may be a plurality of circular arc portions and a plurality of first driving teeth on the first incomplete gear, and when there are a plurality of circular arc portions and a plurality of first driving teeth, the circular arc portions and the first driving teeth need to be arranged at intervals, and adjacent circular arc portions and the first driving teeth need to be in a staggered state. Of course, in the present embodiment, the arc portions may be provided on both the upper and lower end surfaces of the first incomplete gear, and in this case, two rotation stopping ribs opposite to the arc portions need to be provided on both the upper and lower end surfaces of the intermediate gear. This setting can strengthen driven gear's locking intensity, prevents to cause the cracked problem of stalling muscle because of external force is too big. Moreover, research shows that the arc length of a single arc part is generally not less than 8mm, because if the arc length of the single arc part is too small and is less than 8mm, the rotation stopping rib can still bypass the arc part by actively applying external force to the liquid discharge pipe, so that the driven assembly can still rotate. Accordingly, in the structure of the present embodiment, the arc lengths of the arc portion and the stopper rib are required to be not less than 8 mm. In addition, in this embodiment, the intermediate gear may be provided with two symmetrical rotation stopping ribs to realize rotation stopping function when the intermediate gear rotates forward and backward.
In the embodiment, only one communicating hole is arranged on the plane movable valve plate and is used for communicating with the static valve hole on the static valve plate, so that liquid in a food processor container is discharged only through the communicating hole no matter a liquid discharge pipe is subjected to slurry discharge operation or waste water discharge operation. Simultaneously, the flowing back valve module for food processing machine of this embodiment, the structure is simpler to, the flowing back valve module is at the in-process of flowing back, and logical operation is simpler, and the intercommunicating pore that is used for detecting the fluid-discharge tube to carry out row thick liquid, waste water discharging and plane moving valve piece and the static valve hole of static valve piece in addition closes required detection element that uses and also still less, and the installation is more convenient, the structure is compacter.
In this embodiment, the first driving device and the second driving device may be separate devices and may be driven by different motors. Meanwhile, in this embodiment, the first driving device and the second driving device are driven by the same motor, and gear mechanisms in which an incomplete gear and a complete gear form intermittent transmission are respectively arranged between the first driving device and the driven assembly, and between the second driving device and the planar movable valve plate. The intermittent transmission mechanism is not limited to the gear mechanism of the embodiment, and may also be other transmission mechanisms, for example, the first driving device is a cylindrical pin which rotates periodically, the driven component is a sheave which is driven by the cylindrical pin, and the sheave drives the liquid discharge pipe to rotate, wherein the cylindrical pin and the sheave form a sheave mechanism of intermittent transmission.
It should be further noted that, in this embodiment, the installation housing is installed at the bottom of the pulping container, and corresponding sealing components (not labeled in the figure) are required to be arranged between the installation housing and the pulping container, between the upper static valve plate and the installation housing, between the lower static valve plate and the installation housing, and between the static valve hole of the lower static valve plate and the rear end of the liquid discharge pipe for sealing.

In this embodiment, the first driving device 51 and the second driving device 52 are also driven by the same motor 50. The difference between the present embodiment and the first embodiment is: the first driving device 51 is a first incomplete gear, the second driving device 52 is a second complete gear, and the planar movable valve plate 81 is driven by the second complete gear, wherein the planar movable valve plate 81 is driven by the second complete gear while the driven assembly is driven by the first incomplete gear, and when the first incomplete gear rotates to be separated from the driven assembly, the planar movable valve plate 81 is driven by the second complete gear to rotate to the communication hole 80 to be communicated with the liquid discharge pipe 2.
For a better understanding of the inventive concept of the present invention, the operation of the drain valve assembly when draining slurry and waste water from a food processor is described herein:
a pulp discharging process: as shown in fig. 8, before discharging the slurry, the drain pipe is located at a second predetermined position above the wastewater box, when the slurry in the slurry container needs to be discharged, because the first incomplete gear and the second complete gear are also of an integral structure, the motor drives the first incomplete gear and the second complete gear to simultaneously rotate in a clockwise direction, the first incomplete gear is meshed with the driven component and drives the driven component to rotate, the second complete gear is meshed with the plane movable valve plate and drives the plane movable valve plate to rotate, when the first incomplete gear drives the driven component to drive the drain pipe to rotate to a first predetermined position above the slurry cup (the position indicated by the dotted line in fig. 8 is the position where the drain pipe is located), because the first incomplete gear and the driven component are in intermittent transmission of the incomplete gear, after the drain pipe rotates to the first predetermined position, the first incomplete gear just disengages from the driven component, the liquid discharge pipe does not rotate any more, the second complete gear is a complete gear and still can drive the plane movable valve plate to rotate, when the plane movable valve plate rotates until the communicating hole on the plane movable valve plate is gradually superposed with the static valve holes on the upper static valve plate and the lower static valve plate, the pulping container is communicated with the liquid discharge pipe, and the liquid discharge pipe performs pulp discharge operation on pulp in the pulping container.
And (3) valve closing process: as shown in fig. 9, after the pulp discharging is completed, the second complete gear drives the plane movable valve plate to rotate counterclockwise, so that the communicating hole and the static valve hole are closed, and the pulp making container and the liquid discharge pipe are shut off. Meanwhile, the second complete gear continues to reversely drive the plane movable valve plate to rotate, the first incomplete gear and the second complete gear are of an integral structure and are driven by the same motor, when the second complete gear rotates to mesh the first incomplete gear and the driven assembly again, the first incomplete gear can reversely drive the driven assembly to rotate, and when the driven assembly drives the liquid discharge pipe to rotate to a second preset position above the waste water box, the first incomplete gear just disengages from the driven assembly. According to the program setting, when the drain pipe rotates to a second preset position above the waste water box and keeps still (the position shown by the dotted line in fig. 9 is a waste discharge position of the drain pipe above the waste water box), the second complete gear still drives the plane movable valve plate to rotate until the plane movable valve plate rotates to about 3/4 circles, the pulping container and the drain pipe are still in a shut-off state, the control device controls the motor to stop working, and at the moment, the food processor starts to automatically carry out water inlet and cleaning operations on the pulping container.
The waste discharge process comprises the following steps: as shown in fig. 10, after the pulping container is cleaned, according to the program setting, the motor is restarted and drives the first incomplete gear and the second complete gear to continue rotating in the counterclockwise direction, at this time, the first incomplete gear and the driven component are still in a disengaged state, the drain pipe is still in the second preset position above the waste water box for waste discharge and remains still (the position shown by the dotted line in fig. 10 is the waste discharge position where the drain pipe is above the waste water box), the second complete gear continues to drive the planar movable valve plate to rotate, when the communication hole on the planar movable valve plate is gradually communicated with the static valve hole, the pulping container is communicated with the drain pipe, and the drain pipe performs waste discharge operation on cleaning water in the pulping container.
It should be noted that, in this embodiment, the liquid discharge valve assembly is also provided with a detection device for detecting that the planar moving valve plate rotates to the communication hole and is communicated with the static valve hole, and when the detection device detects a signal, the detection device transmits the signal to the control device to control the motor to stop rotating, so as to realize continuous slurry discharge or waste discharge of the liquid discharge pipe.
It should be noted that, in the present embodiment, the drain pipe and the drain valve work simultaneously, and the drain valve is driven by the second driving device to communicate the pulping container with the drain pipe only after the drain pipe rotates to a predetermined position. The principle of the present embodiment for realizing this idea mainly lies in: the first driving device drives the driven assembly to drive the liquid discharge pipe to rotate, the second driving device drives the plane movable valve plate to rotate relative to the upper static valve plate and the lower static valve plate, the first driving device and the driven assembly are intermittent transmission mechanisms, and the second driving device and the plane movable valve plate are complete gear rotation mechanisms. The former intermittent transmission mechanism can effectively avoid the problem that the valve is opened to drain liquid when the drain pipe does not rotate to the position.
For the embodiment, the intermittent transmission of the first driving device and the driven assembly can be a sheave intermittent transmission mechanism besides the intermittent transmission of the incomplete gear and the gear of the complete gear. For example, the first driving device is a cylindrical pin which rotates periodically, the driven component is a grooved wheel driven by the cylindrical pin, the grooved wheel drives the liquid discharge pipe to rotate, and the cylindrical pin and the grooved wheel form an intermittent transmission grooved wheel mechanism. Of course, the intermittent transmission between the first driving device and the driven assembly in this embodiment is not limited to gear transmission and sheave transmission, but may be other intermittent transmission mechanisms with the same function.
In this embodiment, because the plane moves the valve block and adopts complete gear revolve, it is not high to the load requirement, consequently, the quiet valve block can use silica gel material to make, simultaneously, the plane moves the valve block and can adopts conventional plastics, for example POM, PA etc. the quiet valve block adopts flexible material more to be favorable to the seal and the friction between quiet valve block and the valve block that moves, and sealed effect is better, and the cost is also lower.
Example three:
fig. 11 shows a third embodiment of the drain valve assembly for a food processor of the present invention. The present embodiment is different from the above embodiments in that: in this embodiment, the first driving device 51 is a first full gear, and the second driving device 52 is a second full gear. Therefore, the driven component and the plane movable valve plate rotate synchronously. Wherein, the first complete gear and the driven component form a first group of complete gear transmission mechanism, and the second complete gear and the plane movable valve plate 81 form a second group of complete gear transmission mechanism.
Liquid drainage process: as shown in FIG. 12, when the discharge pipe 2 is at the position for discharging the slurry above the slurry receiving cup 3, the communicating hole of the flat movable valve plate 81 is overlapped and communicated with the static valve hole, and the discharge pipe 2 performs the operation for discharging the slurry. After the slurry is discharged, the planar movable valve plate 81 rotates, the communicating hole and the static valve hole on the planar movable valve plate 81 are gradually closed, at this time, the driven component drives the liquid discharge pipe 2 to synchronously move and rotate clockwise along the figure, and when the liquid discharge pipe 2 rotates by an angle alpha, the communicating hole and the static valve hole are completely closed. At this time, the food processor can automatically clean the pulping container, after the automatic cleaning is finished, the liquid discharge pipe 2 rotates again according to the program setting, after the liquid discharge pipe 2 rotates by an angle beta, when the liquid discharge pipe is at the waste discharge position above the waste water box 4, at this time, the plane movable valve plate 81 just moves to the communication hole to be communicated with the static valve hole again, and the liquid discharge pipe 2 starts to perform waste water discharge operation.
In the present embodiment, in order to prevent the drain pipe from starting to drain waste water without rotating to a position above the waste water box, or to start to drain pulp without rotating to a position above the pulp receiving cup. Therefore, it is generally required that α is greater than 20 °, β is less than 120 °, the angle of rotation of the planar movable valve plate from fully open to fully closed is δ, and the gear ratio of the second full gear to the planar movable valve plate is Z1/Z2, then the gear ratio Z3/Z4 of the first full gear to the driven assembly is (Z1 α)/(Z2 δ).
Of course, in this embodiment, the first driving device and the second driving device may also be driven by different motors, so that the movement between the liquid discharge pipe and the planar movable valve plate is not affected by each other. The transmission of the present embodiment is not limited to the gear transmission, and may be ratchet rotation, helical gear transmission, worm gear transmission, or the like. It should be noted that the above-described structure and variations of the present embodiment can also be applied to other embodiments of the present invention.
It will be appreciated by those skilled in the art that the present invention includes, but is not limited to, those illustrated in the accompanying drawings and described in the foregoing detailed description. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
