The linkage body 3 is provided with the pulp discharging channel 301 and the residual water discharging channel 302, the connection or disconnection of the liquid discharging channel 100, the pulp discharging channel 301 and the residual water discharging channel 302 is controlled by the linkage body 3 matching with the movement of the valve core 2, a liquid discharging pipe can be replaced by the linkage body 3, even if the liquid discharging pipe is arranged, the liquid discharging pipe can be directly fixed on the valve body 1, the rotation switching position of the liquid discharging pipe is not required, the reliable realization of the pulp discharging function and the residual water discharging function is ensured, the condition that the liquid discharging pipe cannot be accidentally blocked to rotate to the position to cause that pulp or cleaning residual water is discharged to the outside of a pulp receiving cup or a residual water box is eliminated, and a user can be powerfully ensured to obtain good use experience.

Specifically, there are various ways of opening or closing the inlet of the liquid discharge passage 100 by the valve body 2 and ways of moving the interlocking body 3 in cooperation with the valve body 2, which will be described below by way of example.

The first embodiment is as follows:

as shown in fig. 1 to 7, in one embodiment, the liquid discharge passage 100 is provided in the valve body 2, an inlet of the liquid discharge passage 100 is provided on a peripheral side surface of the valve body 2, and the valve body 2 is rotated relative to the valve body 1 to open or close the inlet of the liquid discharge passage 100. In order to let case 2 rotatory, can set up flowing back motor 4, flowing back motor 4's output shaft can be directly with case 2 fixed connection, also can drive case 2 rotatory through common transmission structure.

Referring to fig. 1, 1A, 2 and 2A, as will be appreciated by those skilled in the art, the valve core 2 may be disposed entirely within the valve body 1, the communication port 101 is disposed on the valve body 1, the drain valve is mounted on the cup body 8 of the food processor, the bottom of the cup body 8 is provided with a drain port 801, the communication port 101 is in communication with the drain port 801, the valve core 2 is rotated by a certain angle, the inlet of the drain channel 100 is aligned with the communication port 101, so that the inlet of the drain channel 100 is opened, the inlet of the drain channel 100 is communicated with the drain port 801, and the liquid in the cup body 8 flows into the drain channel 100, as shown by the arrows in fig. 1A and 2A. The valve body 1 closes the inlet of the liquid discharge passage 100 while being covered by the communication port 101. In another case, it is also possible to design that one end of the valve core 2 extends out of the valve body 1, the inlet of the liquid discharge channel 100 is located at the end of the valve core 2 extending out of the valve body 1, the bottom of the cup body 8 is provided with a plug groove, the liquid discharge port 801 is located on the side wall of the plug groove, the end of the valve core 2 is inserted into the plug groove to be matched and sealed to a certain extent, the valve core 2 rotates to enable the inlet of the liquid discharge channel 100 to be directly aligned and communicated with the liquid discharge port 801, the valve core 2 continues to rotate, and the inlet of the liquid discharge channel 100 is staggered with the liquid discharge port 801 and is covered and closed by the side wall of the plug groove.

In one embodiment, the linkage body 3 can be selectively driven by the valve core 2 to move relative to the valve body 1. As shown in fig. 7, the valve core 2 may be provided with a driving gear 21, the linkage body 3 may be provided with a driven gear 31, and the driven gear 31 is engaged with the driving gear 21 to rotate the linkage body 3 under the driving of the valve core 2. The gear transmission is stable and reliable, and is also beneficial to the accurate control of the rotating positions of the valve core 2 and the linkage body 3.

The coupling body 3 may be installed outside the valve body 1, but in order to eliminate the unexpected influence of the outside on the movement of the coupling body 3, in one embodiment, the coupling body 3 may be installed inside the valve body 1, and in order to ensure the sealing connection between the outlet of the liquid discharge channel 100 and the slurry discharge channel 301 or the residual water discharge channel 302, a sealing surface 102 for the coupling body 3 to move may be provided inside the valve body 1, and the outlet of the liquid discharge channel 100 is located on the sealing surface 102. Besides the hard sealing, the soft sealing can be added on the basis to improve the sealing effect, for example, the linkage body 3 is provided with the sealing gasket 32, the sealing gasket 32 is provided with a through hole 321 which is respectively aligned and communicated with the slurry discharge channel 301 and the residual water discharge channel 302, and the sealing gasket 32 is in contact sealing with the sealing surface 102.

For convenience of description, it can be defined that the interlocking member 3 is in the pulp discharging position (i.e. the state shown in fig. 4) when the outlet of the liquid discharging channel 100 is communicated with the pulp discharging channel 301, and is in the residual water discharging position (i.e. the state shown in fig. 5) when the outlet of the liquid discharging channel 100 is communicated with the residual water discharging channel 302, and in order to increase the reliability when the liquid discharging valve is closed, the interlocking member 3 can be designed to have a closing position (i.e. the state shown in fig. 6) for closing the outlet of the liquid discharging channel 100, and in addition, the valve core 2 closes the inlet of the liquid discharging channel 100, so that the double closing effect can be formed, and the closing position is located between the pulp discharging position and the residual water discharging position, so that the situation that the liquid discharging channel 100 is opened accidentally during the position switching process can not occur.

Since the linkage body 3 has at least two positions and the valve core 2 has two states of opening and closing the inlet of the drainage channel 100, in order that the valve core 2 can open the inlet of the drainage channel 100 when the linkage body 3 is at the drainage position and the valve core 2 can also open the inlet of the drainage channel 100 when the linkage body 3 is at the drainage position, the driving gear 21 can be designed into an incomplete gear, the valve core 2 can drive the linkage body 3 to rotate intermittently, for example, when the linkage body 3 is at the drainage position, the valve core 2 opens the inlet of the drainage channel 100, then the driving gear 21 is disengaged from the driven gear 31, the valve core 2 continues to rotate to close the inlet of the drainage channel 100, the linkage body 3 keeps still, the slurry in the drainage channel 100 can continue to be discharged, and when the cleaning residual water needs to be discharged, the valve core 2 continues to rotate to re-engage the driving gear 21 with the driven gear 31, when the valve core 2 rotates to the position of opening the inlet of the drainage channel 100, the linkage body 3 just moves to the drainage position, and the linkage body 3 can repeatedly move between the drainage position and the residual water discharge position as long as the valve core 2 continues to rotate. Besides, the number of rotation turns of the valve core 2 and the number of rotation turns of the linkage body 3 can be designed to form a certain proportion, for example, one rotation turn of the valve core 2 can drive the linkage body 3 to rotate to the residual water discharging position from the residual water discharging position, and one rotation turn of the valve core 2 can drive the linkage body 3 to rotate to the residual water discharging position from the residual water discharging position. The prior art in this respect is numerous and is not illustrated here.

In some types of food processor, the slurry receiving cup is located at a distance from the outlet of the slurry discharge channel 301, for example, as shown in fig. 1 and 1A, in order to allow slurry to be discharged into the slurry receiving cup 7 and prevent the slurry from being discharged to the outside of the slurry receiving cup 7, the drain valve may be designed to further include a drain pipe 5, the slurry discharge channel 301 is communicated with the drain pipe 5, and the residual water box is located right below the residual water discharge channel, so that the washing residual water can be directly discharged into the residual water box through the residual water discharge channel without connecting the drain pipe. If the distance between the residual water box 6 in a certain machine type and the outlet of the residual water discharging channel 302 is far, the cleaning residual water is prevented from being discharged to the outside of the residual water box 6, and a drain pipe can be communicated with the residual water discharging channel 302. And the drain pipe can rotate between the residual water box and the slurry receiving cup to drain.

In another embodiment, if the slurry receiving cup 7 and the residual water box 6 are both located at a certain distance from the drain valve, the drain valve may further comprise a slurry discharge pipe and a residual water discharge pipe, the slurry discharge passage 301 is communicated with the slurry discharge pipe, and the residual water discharge passage 302 is communicated with the residual water discharge pipe.

In some models, the surplus water tank 6 is not necessary, and the washing surplus water may be directly discharged into the sewer line.

The second embodiment:

in order to allow the valve core 2 to drive the linkage body 3 to switch positions, as shown in fig. 8, the valve core 2 of the present embodiment is provided with a driving gear 21, the linkage body 3 is provided with a rack 33, and the rack 33 is engaged with the driving gear 21 to make the linkage body 3 reciprocate along the rack under the driving of the valve core 2. Fig. 9 shows the linkage body 3 at the slurry discharge position, and fig. 10 shows the linkage body 3 at the residual water discharge position.

Other contents not described in this embodiment may refer to embodiment one.

Example three:

instead of rotating the valve body 2 to open or close the inlet of the drain passage 100, the valve body 2 may be reciprocated relative to the valve body 1 to open or close the inlet of the drain passage 100. The reciprocating movement referred to herein means reciprocating movement along a straight line or reciprocating movement along an arc, and there is a certain difference from the rotating movement in the above-described embodiment.

As shown in fig. 11 to 14, in the present embodiment, the liquid discharge passage 100 may be selectively provided in the valve body 1, the inlet of the liquid discharge passage 100 is located on the valve body 1, and the valve element 2 reciprocates in the liquid discharge passage 100 to open or close the inlet of the liquid discharge passage 100.

Since the valve core 2 reciprocates, the linkage body 3 can move in coordination with the valve core 2 in an electrically controlled manner, for example, the drain valve further includes a valve core driver 4A for driving the valve core 2 to move and a linkage body driver 4B for driving the linkage body 3 to move.

In order to enable the valve core 2 to reciprocate, and considering the small structural size, the valve core driver 4A may be an electric screw, an internal thread matched with the electric screw is fixed on the valve core 2, the valve core 2 is limited to be unable to rotate, and the electric screw rotates forward and backward, so as to enable the valve core 2 to reciprocate on the electric screw, thereby driving the valve core 2 to reciprocate. If the valve core 2 is required to move back and forth along an arc, the valve core 2 can be movably connected with the pull rod through the pull rod, and then the pull rod is driven to move back and forth through the driver. The interlocking body driver 4B may be a motor.

Other contents not described in this embodiment may refer to embodiment one.

Example four:

on the basis of the reciprocating movement of the valve core 2, in order to make the valve core 2 drive the linkage body 3 to switch positions, a rack can be arranged on the valve core 2, a driven gear 31 is arranged on the linkage body 3, and the driven gear 31 is meshed with the rack to make the linkage body 3 rotate under the driving of the valve core 2. This eliminates the need for a linkage driver.

The engagement of the driven gear 31 with the rack may be a direct contact engagement such that the axis of rotation of the coupling body 3 is perpendicular to the axis of the valve body 2, thus requiring the drain passage 100 to be designed as a curve. It is understood that the driven gear 31 may be engaged with the rack in a transition manner by a bevel gear, so that the axis of the linkage body 3 is parallel to the axis of the valve core 2.

Reference may be made to example three for other content not described in this embodiment.

It will be appreciated that in the above embodiments, the valve core 2 may drive the interlocking member 3 by other conventional transmission members, besides using a gear transmission structure. The valve core 2 can move in an electric mode, and can be manually controlled by a user, so that the participation sense of the user is increased, and the use experience can be improved for some users who like to use hands.

Example five:

a food processor can refer to fig. 1 and fig. 2, and comprises a body 9 and a cup body 8 arranged on the body 9, wherein a liquid outlet 801 is arranged at the bottom of the cup body 8, a liquid outlet valve is arranged at the liquid outlet 801, the liquid outlet valve adopts the liquid outlet valve for the food processor in any one of the embodiments, and a valve body 1 is fixedly connected to the cup body 8.

Other contents not described in the present embodiment may refer to the above-described embodiments.

In addition to the preferred embodiments described above, there are other embodiments of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the spirit of the present invention, which is defined in the appended claims.
