Wherein, the valve core 22 is provided with a filter opening 221 and a slag discharge opening 222 which are communicated with the liquid discharge channel 220 in the circumferential direction, the filter opening 221 is provided with dense filter meshes 2210, the valve core 22 is rotated to enable the liquid discharge channel 220 to be communicated with the pulping cavity 1 through the filter opening 221 or the slag discharge opening 222, when the liquid discharge channel 220 is communicated with the pulping cavity 1 through the filter opening 221, the serous fluid in the pulping cavity 1 is filtered through the filter meshes 2210, and the filtered serous fluid is discharged through the liquid discharge channel 220, and when the liquid discharge channel 220 is communicated with the pulping cavity 1 through the slag discharge opening 222, the serous fluid in the pulping cavity 1 is discharged through the slag discharge opening 222 and the liquid discharge channel 220.

In this embodiment, the valve seat 21 includes an upper valve seat 211 and a lower valve seat 212, the upper valve seat 211 and the lower valve seat 212 enclose to form a mounting cavity 210, a driving wheel 24 driven by the driving motor 23 to rotate is installed in the mounting cavity 210, a driving tooth 241 is provided on the driving wheel 24, an annular driven tooth 224 is provided on the outer wall of the valve core 22, wherein a part of the driven tooth 224 extends into the mounting cavity 210, and the driving wheel 24 drives the valve core 22 to rotate through the engagement of the driving tooth 241 and the driven tooth 224.

To this embodiment, because be provided with on the case of flowing back valve can with the filter orifice and the row cinder notch of slurrying cavity alternative intercommunication, consequently, the thick liquid in the slurrying cavity can filter through the filter orifice is automatic to discharge the slurrying cavity through flowing back passageway again, realize the thick liquid drink taste that makes and promote, no matter the thick liquid that the affiliated crowd of consumer can both experience completely not have the sediment and feel. Meanwhile, after filtration, when the valve core rotates to the slag discharge port and is communicated with the pulping cavity, under the combined action of cleaning water or other cleaning media, residual pulp in the pulping cavity can be automatically discharged to the outside through the slag discharge port and the liquid discharge channel. Compared with the existing food processor capable of automatically filtering and discharging slag, the food processor of the embodiment has the advantages that the structure is simpler, and the cleaning of the pulping cavity is cleaner because the filtering device is not arranged in the pulping cavity. In addition, because the pulping cavity of this embodiment does not have soaking filter equipment in, wherein, filter mesh sets up on the case, when the thick liquid in the pulping cavity is boiled, filter mesh on the case and the liquid outlet dislocation of pulping cavity are closed, and filter mesh on the case does not with thick liquid direct contact, consequently, can not take place to filter the mesh and because of the pasting problem that is blockked up of thick liquid sediment, more can not take place to filter when needing, the thick liquid filters not smooth problem.

It should be noted that, in this embodiment, the valve core includes a valve core body and a filter screen, wherein the filter opening is disposed on the valve core body and is communicated with the liquid discharge channel, the filter screen is disposed at the filter opening, and the filter screen opening is formed on the filter screen. In the embodiment, the mesh number of the filter screen is 50-1000 meshes, and when the mesh number of the filter screen is less than 50 meshes, a consumer can strongly perceive the residue feeling of the soybean milk when drinking the soybean milk, so that the embodiment requires the filter screen to be selected to be more than 50 meshes. However, when the mesh number of the filter net is greater than 1000 meshes, the diameter of the filter net is small, and when the soybean milk is filtered, the soybean milk is difficult to discharge smoothly, and the soybean milk discharge speed is too slow. Therefore, the filter screen of the present embodiment is required to be selected to be less than 1000 meshes at the same time. In this embodiment, the sieve is preferably 80-200 mesh.

Meanwhile, in the present embodiment, since the drain valve has a function of filtering the soybean milk, the inner diameter of the drain passage in the valve core is required to be large, and the inventor of the present invention found through research that the equivalent inner diameter of the cross section of the drain passage is required to be not less than 15mm in order to enable smooth discharge of the soybean milk when filtering the soybean milk, and the drain passage is preferably 20mm to 40mm for the household food processor. Because the inner diameter of the liquid drainage channel is too large, in the process of discharging pulp or waste water, more residue and waste water are remained in the liquid drainage channel. Of course, for the present embodiment, the shape of the valve core is not limited to a cylindrical shape, but may also be a conical cylinder shape, and the shape of the liquid discharge passage is not limited to a cylindrical shape with an equal inner diameter in cross section, but may also be other shapes, such as a conical cylinder shape with a frustum cross section or a square cylinder shape with a square cross section. Moreover, for the embodiment, along the discharging direction of the slurry, the inner diameter of the tail end of the liquid discharging channel is smaller than that of the starting end, so that the liquid is more favorably converged and discharged, and the liquid discharging or slag discharging efficiency is improved.

In the present embodiment, the circumferential width of the filtering port is B1, and the circumferential width of the slag discharging port is B2, wherein B1> B2 is required. The inventor finds that when the B1 is larger than the B2, the filtering efficiency of the slurry is higher and the slurry discharging speed is higher in the slurry filtering and discharging process of the drain valve. Because, at filterable in-process, the liquid outlet of slurrying cavity can remain throughout with filter opening is full-open, moreover, can also realize the limit and filter, case limit rotation, because, the case is at the pivoted in-process, and the filter screen on the case can scrape on the inner wall of disk seat to let remaining thick liquid sediment on the filter screen be scraped by the disk seat, thick liquid sediment is unlikely to block up the filter mesh hole. In the present embodiment, the circumferential widths B1 and B2 of the filter opening and the slag discharge opening refer to the circumferential arc lengths of the filter opening and the slag discharge opening. Of course, the inventors of the present invention have found through their studies that in a configuration in which filtration and drainage are performed using a drain valve, B1/B2 is required to be 1.1 to 4, and when B1/B2 is less than 1.1, there is a problem in that filtration efficiency and drainage rate are significantly reduced. When the ratio B1/B2 is greater than 4, the design of the slag discharge port is limited, and the slag discharge efficiency may be affected during slag discharge. For the present embodiment, B1/B2 is preferably 1.5-2.

As mentioned above, in the process of filtering the slurry in the pulping cavity by the drain valve, the valve core can rotate relative to the valve seat so as to realize scraping of the filter screen on the valve core and the valve seat and prevent slurry residue from blocking the filter screen holes. Therefore, in this embodiment, the case can be relatively reciprocating's of disk seat rotation back and forth to, at reciprocating rotation's in-process, the filter opening keeps and makes milk cavity intercommunication, realizes that the filter screen scrapes thick liquid sediment, filters thick liquid simultaneously. Certainly, in the reciprocating rotation process of the valve core, the filter port can be communicated with the pulping cavity intermittently, at the moment, pulp residue scraping and pulp filtering are alternately carried out, and at the moment, the valve core intermittently rotates relative to the valve seat. It should be noted that, because the valve core is provided with the slag discharge port and the filter port, the valve core is only limited to reciprocating rotation in the process of filtering the slurry, so as to scrape the slurry slag and realize filtering and rotating. And when the valve core is only arranged at the filter port and does not have a slag discharge port, the liquid discharge valve only has a filtering function and does not have a slag discharge function, and in the filtering process, the valve core can rotate in a reciprocating manner and can rotate continuously in one direction, and when the valve core rotates continuously in one direction, the pulping cavity can be intermittently communicated with the filter port for filtering.

In addition, it should be noted that, in this embodiment, the bottom of the pulping chamber body is provided with a pressurizing chamber, wherein the volume of the pressurizing chamber is not more than 600 mL. In filterable in-process, because the volume in pressure boost chamber is less, formed little space, when smashing the cutter and rotating, the thick liquid can be got rid of to the liquid outlet under the effect of centrifugal force, liquid outlet department pressure increase to promote the filterable efficiency of thick liquid, increased the speed of arranging the thick liquid. Similarly, if the pulping cavity is a closed pressure cavity, in the filtering process, when the pressure in the pulping cavity is greater than the external atmospheric pressure, pressure pulp discharging can be realized, and the efficiency of pulp discharging and filtering is improved.

It should be noted that, the variations of the above-mentioned structures and the selection of the parameters in the present embodiment can be applied to other embodiments of the present invention.

The drain pipe 29 in this embodiment is rotatable relative to the valve seat 21, and a pulp receiving cup 41 and a waste water box 42 are provided below the drain pipe 29. When the valve core 22 rotates to a filtering opening (not shown in the figure) to be communicated with the pulping cavity 1, the liquid discharge pipe 29 rotates to the upper part of the pulp receiving cup 41, and the pulp is filtered through the filtering opening and discharged into the pulp receiving cup 41 through the liquid discharge channel 220 and the liquid discharge pipe 29. After filtering, water is fed into the pulping cavity 1 to clean the pulping cavity 1 and mix pulp slag in the pulping cavity 1, when discharging slag, the valve core 22 rotates to a slag discharge port (not shown) to be communicated with the pulping cavity 1, the liquid discharge pipe 29 rotates to the upper part of the waste water box 42, and the pulp slag in the pulping cavity 1 is discharged into the waste water box 42 through the slag discharge port, the liquid discharge passage 220 and the liquid discharge pipe 29.

The drain valve of the present embodiment also has a self-cleaning function because slurry residue may still be attached to the drain passage 220. When the drain valve is cleaned, the valve body 22 is rotated to connect the second input port 229 and the first input port 219, the cleaning medium supplied from the supply device 5 can enter the first input port 219 and the second input port 229, the drain passage 220 is pressure-flushed, and the cleaning medium flushed through the drain passage 220 is discharged to the waste water box 42 through the drain pipe 29.

To this embodiment, because the flowing back valve has the function of self-cleaning, can promote the scavenging degree of flowing back passageway greatly, the effectual problem that has had peculiar smell and breed the bacterium because of remaining the thick liquid sediment in the flowing back passageway that has prevented. In addition, the cleaning of the filter meshes can be realized in the cleaning process of the liquid discharge channel, and the filter meshes are prevented from being blocked. In addition, after foreign matter blockage occurs in the drain valve, the foreign matter can be discharged by flushing the high-pressure cleaning medium supplied by the supply device, so that the foreign matter discharging capacity of the drain valve is greatly improved, and the foreign matter discharging operation is simpler. Meanwhile, the present embodiment has the same advantageous effects as the first embodiment.

It should be noted that, for the present embodiment, the supply device may be a water supply device that supplies cleaning water into the drain valve, and the drain channel is flushed by the pressure of the cleaning water; the liquid discharging channel can be cleaned by impacting high-pressure gas by a gas supply device for supplying gas into the liquid discharging valve; the steam generator for supplying steam into the drain valve may fumigate, soften and clean the residue in the drain passage with the supplied high-temperature steam.

It should be noted that, for the embodiment, the second input port disposed on the valve core may also be a filter port, when the drain valve is self-cleaned, the valve core rotates to the filter port to communicate with the first input port, and the cleaning medium supplied by the supply device can clean the filter mesh at the filter port first, and then clean the drain passage. Of course, the second input port may also be a slag discharge port, and a developer may design the second input port according to requirements. Meanwhile, it should be noted that, in this embodiment, the cleaning medium supplied by the supply device is discharged into the waste water box after the liquid discharge channel is washed, and the research and development staff may also set the cleaning medium according to the requirement, so as to discharge the cleaning medium after the liquid discharge channel is washed to the pulp making cavity, thereby cleaning the pulp making cavity.

In this embodiment, the drain pipe is driven by the valve core to rotate relative to the valve seat. Of course, the drain pipe and the valve core can also be driven by the same driving device, but the drain pipe and the valve core rotate asynchronously, and research personnel can design according to specific requirements.

It should be noted that the above structural changes for 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.
