Description

Technical Field

[0001] The invention relates to the technical field of food processing machines, and in particular to a food processing machine. Background Art

[0002] For kitchen appliances, people have always been unable to get out of the kitchen because they require too much human participation. With the continuous development of science and technology, more and more intelligent technologies are also applied to kitchen appliances. In order to further facilitate users, a self-cleaning food processor has emerged.

[0003] The existing self-cleaning food processing machine is equipped with a pulp receiving cup, a residual water box, a water tank, a grinding chamber and a valve assembly, wherein the valve assembly generally includes a valve core, a motor for driving the valve core to rotate, and a drainage pipe for discharging pulp. A pulp discharge hole is provided at the bottom or bottom side of the grinding chamber, and a valve assembly for closing or opening the pulp discharge hole is provided at the pulp discharge hole. When the raw material is processed in the grinding chamber, the valve assembly is closed. When the corresponding food processing is completed or the food in the grinding chamber needs to be discharged, the drainage pipe is rotated to the pulp discharge position corresponding to the pulp receiving cup, and the valve core continues to rotate to open the valve assembly, so that the food in the grinding chamber flows into the pulp receiving cup; when cleaning, the valve assembly is also closed. When cleaning is completed or the cleaning water needs to be discharged, the position of the drainage pipe needs to be rotated to the waste water discharge position corresponding to the residual water box, and the valve core continues to rotate to open the valve assembly to ensure that the cleaning water is discharged into the residual water box.

[0004] The existing drain pipe rotates between the slurry receiving position and the wastewater discharge position only by relying on the friction between it and the valve core. For example, the patent application document with application number CN201911361931.3 discloses a food processing machine, which realizes the valve core driving the drain pipe to rotate by matching the slot on the valve core with the buckle on the drain pipe or the two gears. However, this transmission method causes the drain pipe to be hard-separated from the valve core after reaching the predetermined position. When hard-separated, there is a lot of resistance between the drain pipe and the valve core, causing a large load on the drive motor, affecting the life of the drive motor, and long-term use will cause serious wear of the two components, reducing the friction between the two. When the friction is small, the drain pipe will slip with the valve core, the valve assembly will fail, and cause slurry discharge errors. Summary of the invention

[0005] The object of the present invention is to provide a food processing machine to solve the problem that the valve core and the discharge pipe will not slip during the operation of the existing valve assembly, thereby ensuring the reliability of the rotation and separation of the valve core and the discharge pipe.

[0006] To achieve the above-mentioned purpose, the present invention provides a food processing machine, comprising a body with a grinding chamber, a valve assembly arranged outside the grinding chamber, and a pulp receiving cup and a residual water box located below the valve assembly, the valve assembly comprising a valve housing, a valve core rotatably arranged in the valve housing, a motor for driving the valve core to rotate, and a drain pipe connected to the valve core, the drain pipe rotates with the valve core, and driven by the valve core, the drain pipe rotates and switches between the pulp receiving cup and the residual water box, a stop portion is arranged on the valve housing, when the drain pipe rotates to abut against the stop portion, the drain pipe reaches a predetermined position for discharging pulp or discharging waste, and the valve assembly further comprises a linkage mechanism; during the process of the drain pipe rotating to the predetermined position, the linkage mechanism locks the drain pipe with the valve core; when the drain pipe reaches the predetermined position, the stop portion restricts the drain pipe from rotating, and the linkage mechanism unlocks the drain pipe from the valve core, and the valve core continues to rotate driven by the motor until the valve core is connected to the grinding chamber, so as to realize pulp discharge or waste discharge from the drain pipe.

[0007] The present invention provides a food processing machine, by arranging a stopper on the valve housing, and the drain pipe has a predetermined position for discharging pulp or waste when it abuts against the stopper, so as to ensure that the drain pipe can abut against the stopper when it reaches the predetermined position when the valve core rotates, thereby avoiding the situation where the drain pipe rotates past the predetermined position due to excessive rotation angle of the drain pipe. At the same time, the stopper abuts against the drain pipe, so that the drain pipe stays stably at the predetermined position, thereby improving the stability of the drain pipe at the predetermined position and improving the overall stability of the valve assembly.

[0008] In addition, the valve assembly also includes a linkage mechanism, so that when the drain pipe rotates to the predetermined position, the linkage mechanism locks the drain pipe and the valve core, ensuring that the valve core has sufficient friction to drive the drain pipe to rotate so that the drain pipe can reach the predetermined position, avoiding the situation where the drain pipe cannot reach the predetermined position due to the small friction between the drain pipe and the valve core causing the two to slide relative to each other, thereby improving user experience. At the same time, when the drain pipe reaches the predetermined position, the stop portion limits the rotation of the drain pipe and the linkage mechanism unlocks the drain pipe and the valve core, and the valve core continues to rotate under the drive of the motor, so that when the drain pipe reaches the predetermined position, the drain pipe can be separated from the valve core, ensuring that the valve core can continue to rotate smoothly, reducing the wear of both, and at the same time reducing the load of the motor and extending the service life of the motor.

[0009] In a preferred implementation of the valve assembly, the linkage mechanism includes a locking member arranged on the discharge pipe and a driving tooth arranged on the outer surface of the valve core; when the discharge pipe is rotated to a predetermined position, the locking member engages with the driving tooth; when the discharge pipe reaches the predetermined position, the locking member separates from the driving tooth.

[0010] By setting the linkage component as a locking piece on the drain pipe and a driving tooth on the outer surface of the valve core, the transmission efficiency of the drain pipe and the valve core is improved. The drain pipe and the valve core can be locked through the engagement of the locking piece and the driving tooth. The structure is simple and easy to assemble, which reduces production costs and improves production efficiency.

[0011] In a preferred implementation of the valve assembly, a slide is provided in the valve housing, and the linkage mechanism also includes a first slider and a second slider provided on the discharge pipe, a locking piece is clamped between the first slider and the second slider, the first slider and the second slider both extend into the slide, and the side wall of the slide limits the first slider and the second slider so that one of the first slider and the second slider is close to or away from the driving tooth; when the discharge pipe is rotated to a predetermined position, the slide makes the first slider and the second slider both close to the driving tooth so that the locking piece engages with the driving tooth; when the discharge pipe reaches the predetermined position, the slide allows one of the first slider or the second slider to slide in a direction away from the driving tooth so that the locking piece is separated from the driving tooth.

[0012] By arranging the first slider and the second slider on the discharge pipe, when the discharge pipe rotates to a predetermined position, the first slider and the second slider both approach the driving teeth, ensuring that the locking member can mesh with the driving teeth, and the first slider and the second slider have a limiting effect on the locking member, thereby improving the stability of the locking member and avoiding the situation in which the locking member and the driving teeth are separated due to shaking of the locking member during the rotation process and the discharge pipe cannot be driven. At the same time, the use of the slideway can realize the first slider or the second slider approaching or moving away from the driving teeth, with a simple structure and fewer parts, thereby reducing costs and improving production efficiency.

[0013] In a preferred implementation of the valve assembly, a slide is provided in the valve housing, and the linkage mechanism also includes a first slider and a second slider provided on the discharge pipe, a locking piece is clamped between the first slider and the second slider, the first slider and the second slider both extend into the slide, and the side walls of the slide limit the first slider and the second slider so that one of the first slider and the second slider is close to or away from the driving tooth; when the discharge pipe is rotated to a predetermined position, the slide causes the first slider or the second slider to approach the driving tooth to limit the locking piece, so that the locking piece engages with the driving tooth; when the discharge pipe reaches the predetermined position, the slide allows the first slider or the second slider to slide in a direction away from the driving tooth to separate the locking piece from the driving tooth.

[0014] By arranging the first slider and the second slider on the discharge pipe, when the discharge pipe rotates to a predetermined position, the first slider and the second slider both approach the driving teeth, ensuring that the locking member can mesh with the driving teeth, and the first slider and the second slider have a limiting effect on the locking member, thereby improving the stability of the locking member and preventing the locking member from shaking during the rotation process, resulting in the locking member being separated from the driving teeth and failing to drive the discharge pipe. At the same time, the use of the slideway can realize the first slider and the second slider approaching or moving away from the driving teeth, with a simple structure and fewer parts, thereby reducing costs and improving production efficiency.

[0015] In a preferred implementation of the valve assembly, the discharge pipe includes a slurry pipe and a slurry pipe sleeve connecting the slurry pipe to the valve core, the slurry pipe sleeve is provided with a radially outwardly protruding boss, the first slider and the second slider are slidably arranged on the boss, the locking member is a rocker rod passing through the boss, and the rocker rod is provided with a tooth opening that cooperates with the driving tooth.

[0016] By providing a boss protruding outward on the slurry pipe sleeve for placing the first slider, the second slider, and the locking member, the overall volume of the slurry pipe sleeve will not be too large, reducing the space occupied by the slurry pipe sleeve, making the structure of the entire valve assembly more compact, and helping to achieve miniaturization. At the same time, the locking member is a swing rod penetrating the boss, and the swing rod is provided with a tooth opening that cooperates with the driving tooth, which further improves the stability of the locking member and the driving tooth, reduces the probability of slipping when the valve core drives the locking member to rotate, and thus improves the stability of the transmission.

[0017] In a preferred implementation of the valve assembly, the valve housing is provided with a rib, the discharge pipe is provided with a slide groove, the locking member is slidably disposed in the slide groove and can slide along the radial direction of the discharge pipe, the rib abuts against an end of the locking member away from the driving tooth to drive the locking member to slide, and the rib is divided into a fixed section and a retreat section;

[0018] By setting the ribs as fixed sections and retreat sections, when the discharge pipe rotates to a predetermined position, the fixed section allows the locking member to approach the driving teeth so that the locking member engages with the driving teeth, and the inner wall of the fixed section abuts against the side wall of the locking member to ensure the stability of the engagement between the locking member and the driving teeth, thereby reducing the probability of slippage when the valve core drives the locking member to rotate, thereby improving the stability of the transmission. At the same time, when the discharge pipe reaches the predetermined position, the retreat section allows the locking member to slide in a direction away from the driving teeth so that the locking member is separated from the driving teeth, thereby reducing the wear of the locking member and the driving teeth, and at the same time reducing the load of the motor and extending the service life of the motor.

[0019] In a preferred implementation of the valve assembly, the retreat section includes a left retreat section arranged on the left side of the fixed section and a right retreat section arranged on the right side of the fixed section. When the valve core rotates forward, the right retreat section allows the locking member to slide, and when the valve core rotates reversely, the left retreat section allows the locking member to slide.

[0020] By providing the left retreat section and the right retreat section, the locking member can be separated from the driving tooth when the valve core reaches a predetermined position in both forward and reverse rotations, further reducing the wear of the locking member and the driving tooth and extending the service life of the locking member and the valve core.

[0021] In a preferred implementation of the valve assembly, the linkage mechanism further includes a reset mechanism, which drives the locking member to reset to a position meshing with the driving tooth.

[0022] By setting a reset mechanism, the locking member can automatically reset to a position engaging with the drive tooth after the discharge pipe is rotated into place, ensuring that when the discharge pipe needs to be rotated in the opposite direction, the locking member can smoothly and quickly engage with the drive tooth so that the valve core can drive the discharge pipe to rotate.

[0023] In a preferred implementation of the valve assembly, the discharge pipe is provided with a corrugated surface, the locking member cooperates with the corrugated surface and the locking member sleeve is provided with a spring, the spring and the corrugated surface constitute a reset mechanism to rotate and reset the locking member; or, the reset mechanism is a torsion spring.

[0024] By providing a corrugated surface on the discharge pipe, the locking member cooperates with the corrugated surface and the locking member sleeve is provided with a spring, so that when the locking member is separated from the driving tooth, under the action of the spring and the corrugated surface, the locking member can automatically return to the state of meshing with the driving tooth, providing a guarantee for the reverse rotation of the discharge pipe. Alternatively, the reset mechanism is provided as a torsion spring, which can also achieve the above effect, and the structure is simple and easy to assemble.

[0025] In a preferred implementation of the valve assembly, the linkage mechanism also includes an auxiliary transmission member; when the discharge pipe is rotated to a predetermined position, the auxiliary transmission member and the locking member are synchronously engaged with the driving teeth; when the discharge pipe reaches the predetermined position, the auxiliary transmission member and the locking member are synchronously separated from the driving teeth.

[0026] By providing an auxiliary transmission member, the locking member and the auxiliary transmission member can simultaneously drive the drain pipe to rotate, thereby reducing the load of the locking member, avoiding the possibility of damage to the locking member due to being under high load for a long time, and further ensuring the stability of the transmission between the valve core and the drain pipe. In addition, when the drain pipe reaches a predetermined position, the auxiliary transmission member and the locking member are synchronously separated from the driving teeth, thereby reducing the wear of the secondary main transmission member, the locking member and the driving teeth, extending their service life, and reducing the load of the motor, thereby extending the service life of the motor.

[0027] In a preferred implementation of the valve assembly, the linkage mechanism includes an electromagnet, one of the drain pipe and the valve core is provided with an electromagnet, and the other cooperates with the electromagnet; when the drain pipe rotates to a predetermined position, the electromagnet locks the drain pipe and the valve core; when the drain pipe reaches the predetermined position, the electromagnet unlocks the drain pipe and the valve core.

[0028] By configuring the linkage mechanism as an electromagnet or other structure, the structure is simple and easy to assemble, and the electromagnet is more stable and reliable during use, thus avoiding failure after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0048] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] In one embodiment, Figure 2-6 As shown, a valve assembly includes a valve housing 1, a valve core 4 rotatably arranged on the valve housing 1, a motor 2 for driving the valve core 4 to rotate, and a drain pipe 3 connected to the valve core 4, the drain pipe 3 rotates with the valve core 4, the valve housing 1 is provided with a stop portion, the drain pipe 3 has a predetermined position abutting against the stop portion, and the valve assembly also includes a linkage mechanism 5; when the drain pipe 3 rotates to the predetermined position, the linkage mechanism 5 locks the drain pipe 3 and the valve core 4; when the drain pipe 3 reaches the predetermined position, the stop portion restricts the rotation of the drain pipe 3 and the linkage mechanism 5 unlocks the drain pipe 3 and the valve core 4, and the valve core 4 continues to rotate driven by the motor 2.

[0050] The present invention provides a valve assembly, by arranging a stopper on a valve housing 1, and the drain pipe 3 has a predetermined position abutting against the stopper, so as to ensure that the drain pipe 3 can abut against the stopper when it reaches the predetermined position when the drain pipe 3 rotates with the valve core 4, and avoids the situation that the drain pipe 3 rotates too much and causes the drain pipe 3 to rotate past the predetermined position. At the same time, the stopper abuts against the drain pipe 3, so that the drain pipe 3 stays stably at the predetermined position, thereby improving the stability of the drain pipe 3 at the predetermined position and improving the overall stability of the valve assembly.

[0051] In addition, the valve assembly also includes a linkage mechanism 5, so that when the drain pipe 3 rotates to the predetermined position, the linkage mechanism 5 locks the drain pipe 3 and the valve core 4, ensuring that the valve core 4 has sufficient friction to drive the drain pipe 3 to rotate so that the drain pipe 3 can reach the predetermined position, avoiding the situation where the drain pipe 3 cannot reach the predetermined position due to the small friction between the drain pipe 3 and the valve core 4 causing relative sliding between the two, thereby extending the service life of the valve assembly and improving the user experience. At the same time, when the drain pipe 3 reaches the predetermined position, the stop portion restricts the rotation of the drain pipe 3 and the linkage mechanism 5 unlocks the drain pipe 3 and the valve core 4, and the valve core 4 continues to rotate under the drive of the motor 2, so that when the drain pipe 3 reaches the predetermined position, the drain pipe 3 can be separated from the valve core 4, reducing the wear of the two, and at the same time, it can also reduce the load of the motor 2 and extend the service life of the motor 2.

[0052] It should be noted that the present application does not specifically limit the mechanism on which the valve assembly is installed. As a preferred embodiment of the present application, Figure 1 , Figure 2 , Figure 3 As shown, the valve assembly is installed on a food processing machine, and the food processing machine is provided with a pulp receiving cup 7, a residual water box 8, a water tank 9, and a stirring cup with a crushing chamber 10. Specifically, the crushing chamber 10 is used for material crushing and heating, and the crushing chamber 10 is automatically filled with water for cleaning. After pulping or cleaning is completed, the motor 2 drives the valve core 4 to rotate, and the linkage mechanism 5 locks the drain pipe 3 and the valve core 4 so that the valve core 4 can drive the drain pipe 3 to rotate and switch between the pulp receiving cup 7 and the residual water box 8. When the drain pipe 3 reaches a predetermined position above the pulp receiving cup 7, the drain pipe 3 is aligned with the pulp receiving cup 7; or when the drain pipe 3 reaches a predetermined position above the residual water box 8, the drain pipe 3 is aligned with the residual water box 8. The stop portion restricts the rotation of the drain pipe 3 and the linkage mechanism 5 unlocks the drain pipe 3 and the valve core 4, and then the valve core 4 continues to rotate under the drive of the motor 2 to open the pulp discharge port connected to the stirring cup to discharge the pulp or waste water in the stirring cup. The above arrangement enables slurry or waste to be discharged only after the drainage pipe 3 is in place, thereby preventing liquid from flowing out during the rotation of the drainage pipe 3 and other components, thereby improving user experience.

[0053] As a preferred embodiment of the present application, Figure 6As shown, the linkage mechanism 5 includes a locking member 51 arranged on the drain pipe 3 and a driving tooth 54 arranged on the outer surface of the valve core 4; when the drain pipe 3 rotates to a predetermined position, the locking member 51 engages with the driving tooth 54; when the drain pipe 3 reaches the predetermined position, the locking member 51 separates from the driving tooth 54.

[0054] By setting the linkage component as a locking piece 51 on the drain pipe 3 and a driving tooth 54 on the outer surface of the valve core 4, the transmission efficiency of the drain pipe 3 and the valve core 4 is improved. The drain pipe 3 and the valve core 4 can be locked by the engagement of the locking piece 51 and the driving tooth 54. The structure is simple and easy to assemble, which reduces production costs and improves production efficiency.

[0055] It should be noted that the present application does not specifically limit the structure of the linkage mechanism 5, which may be any one of the following embodiments:

[0056] Example 1: Figure 5 , Figure 6 As shown, in this embodiment, the valve housing 1 is provided with a slide 11, and the linkage mechanism 5 also includes a first slider 52 and a second slider 53 arranged on the drain pipe 3, and the locking member 51 is clamped between the first slider 52 and the second slider 53. The first slider 52 and the second slider 53 both extend into the slide 11, and the side wall of the slide 11 limits the first slider 52 and the second slider 53 so that one of the first slider 52 and the second slider 53 approaches or moves away from the driving tooth 54; when the drain pipe 3 is rotated to a predetermined position, the slide 11 makes the first slider 52 or the second slider 53 approach the driving tooth 54 so that the locking member 51 is engaged with the driving tooth 54, and prevents the locking member 51 from separating from the driving tooth 54; when the drain pipe 3 reaches the predetermined position, the slide 11 allows one of the first slider 52 and the second slider 53 to slide in a direction away from the driving tooth 54 so that the locking member 51 is separated from the driving tooth 54.

[0057] By arranging the first slider 52 and the second slider 53 on the discharge pipe 3, when the discharge pipe 3 rotates to the predetermined position, the first slider 52 or the second slider 53 approaches the driving tooth 54, ensuring that the locking member 51 can be engaged and locked with the driving tooth 54, and the first slider 52 or the second slider 53 has a limiting effect on the locking member 51, thereby improving the stability of the locking member 51 and preventing the locking member 51 from shaking during the rotation process, resulting in the locking member 51 being separated from the driving tooth 54 and unable to drive the discharge pipe 3. At the same time, the use of the slide 11 can achieve the first slider 52 and the second slider 53 approaching or moving away from the driving tooth 54, with a simple structure and fewer parts, thereby reducing costs and improving production efficiency.

[0058] Furthermore, if Figure 2 , Figure 3 , Figure 4As shown, the discharge pipe 3 includes a slurry pipe 31 and a slurry pipe sleeve 32 connecting the slurry pipe 31 to the valve core 4, the slurry pipe sleeve 32 is provided with a radially outwardly protruding boss 321, the first slider 52 and the second slider 53 are slidably arranged on the boss 321, the locking member 51 is a rocker rod passing through the boss 321, and the rocker rod is provided with a tooth opening 511 cooperating with the driving tooth 54.

[0059] By providing a boss 321 protruding outward on the slurry pipe sleeve 32 for placing the first slider 52, the second slider 53, and the locking member 51, the overall volume of the slurry pipe sleeve 32 will not be too large, reducing the space occupied by the slurry pipe sleeve 32, making the structure of the entire valve assembly more compact, and helping to achieve miniaturization. At the same time, the locking member 51 is a swing rod penetrating the boss 321, and the swing rod is provided with a tooth opening 511 that cooperates with the driving tooth 54, further improving the stability of the locking member 51 and the driving tooth 54, reducing the probability of slipping when the valve core 4 drives the locking member 51 to rotate, thereby improving the stability of the transmission.

[0060] Specifically, Figure 6 As shown, at this time, the drain pipe 3 is in a predetermined position, i.e., the pulp discharge position, the second slider 53 is away from the driving tooth 54 to separate the locking member 51 from the driving tooth 54, and the drain pipe 3 is aligned with the pulp receiving cup 7 for pulp discharge, and then as shown in FIG. Figure 7 As shown in FIG. 1 , the locking member 51 is reset to a position where it meshes with the driving tooth 54 under the drive of the reset mechanism, and the motor 2 drives the valve core 4 to rotate clockwise to gradually move the discharge pipe 3 away from the predetermined position. At this time, the first slider 52 and the second slider 53 both approach the driving tooth 54 to mesh the locking member 51 with the driving tooth 54. Figure 8 As shown, the valve core 4 further rotates forward to make the drain pipe 3 gradually approach another predetermined position, that is, the position for discharging cleaning waste water, such as Figure 5 As shown, the slideway 11 is provided with an arc segment 111 and a flat segment 112. When the first slider 52 moves to the connection between the flat segment 112 and the arc segment 111, the side wall of the slideway 11 guides the first slider 52. The first slider 52 continues to move to the flat segment 112. Under the action of the slideway 11, the first slider 52 is moved away from the driving tooth 54, and the locking member 51 is gradually separated from the driving tooth 51. The valve core 4 further rotates to make the discharge pipe 3 reach another predetermined position, such as Fig. 9 As shown, since the locking member 51 loses the limit of the first slider 52, the locking member 51 is separated from the driving tooth 54, and the drain pipe 3 is aligned with the residual water box 8 to discharge the cleaning waste water.

[0061] It should be further noted that the present application does not specifically limit the number of tooth openings 511. As shown in the figure, it can be one tooth opening 511. Fig.10 As shown, it may also be a plurality of tooth openings 511 .

[0062] Example 2: Fig.13As shown, in this embodiment, the valve housing 1 is provided with a rib 12, the discharge pipe 3 is provided with a slide groove 34 extending in its radial direction, the locking member 51 is slidably arranged in the slide groove 34, the rib 12 abuts against one end of the locking member 51 away from the driving tooth 54 to drive the locking member 51 to slide, and the rib 12 is divided into a fixed section 121 and a retreat section 122;

[0063] By setting the rib 12 as a fixed section 121 and a retreat section 122, when the discharge pipe 3 rotates to the predetermined position, the fixed section 121 makes the locking member 51 approach the driving tooth 54 so that the locking member 51 meshes with the driving tooth 54, and the inner wall of the fixed section 121 abuts against the side wall of the locking member 51 to ensure the stability of the meshing of the locking member 51 with the driving tooth 54, reducing the probability of slipping when the valve core 4 drives the locking member 51 to rotate, thereby improving the stability of the transmission. At the same time, when the discharge pipe 3 reaches the predetermined position, the retreat section 122 allows the locking member 51 to slide in a direction away from the driving tooth 54 so that the locking member 51 is separated from the driving tooth 54, thereby reducing the wear of the locking member 51 and the driving tooth 54, and at the same time can reduce the load of the motor 2 and extend the service life of the motor 2.

[0064] Furthermore, if Fig.14 As shown, the retreat section 122 includes a left retreat section 1221 arranged on the left side of the fixed section 121 and a right retreat section 1222 arranged on the right side of the fixed section 121. When the valve core 4 rotates forward, the right retreat section 1222 allows the locking member 51 to slide. When the valve core 4 rotates reversely, the left retreat section 1221 allows the locking member 51 to slide.

[0065] By providing the left retreat section 1221 and the right retreat section 1222, the locking member 51 can be separated from the driving tooth 54 when the valve core 4 reaches the predetermined position in both forward and reverse rotations, thereby further reducing the wear of the locking member 51 and the driving tooth 54 and extending the service life of the locking member 51 and the valve core 4.

[0066] Specifically, Fig.14 As shown, the drain pipe 3 and the valve core 4 are in a locked state. At this time, the valve core 4 rotates clockwise under the drive of the motor 2, and the locking member 51 approaches the driving tooth 54 under the action of the fixed section 121 so that the locking member 51 meshes with the driving tooth 54, thereby driving the drain pipe 3 to rotate clockwise. Fig.15 As shown, the drain pipe 3 is locked with the valve core 4 and the drain pipe 3 gradually approaches the predetermined position. When approaching the predetermined position, the locking member 51 gradually separates from the driving tooth 54. Fig.16 As shown, when the discharge pipe 3 reaches the predetermined position, the locking member 51 just reaches the right retreat section 1222 and slides in a direction away from the driving tooth 54 to separate the locking member 51 from the driving tooth 54 .

[0067] As a preferred implementation of the present application, Figure 3 , Figure 4As shown, the linkage mechanism 5 further includes a reset mechanism, which drives the locking member 51 to reset to a position meshing with the driving tooth 54 .

[0068] By setting up a reset mechanism, after the drain pipe 3 is rotated into place, the locking member 51 can automatically reset to a position engaged with the driving tooth 54, ensuring that when the drain pipe 3 needs to be rotated in the opposite direction, the locking member 51 can smoothly and quickly engage with the driving tooth 54 so that the valve core 4 can drive the drain pipe 3 to rotate.

[0069] It should be noted that the present application does not specifically limit the structure of the reset mechanism, which can be any one of the following embodiments:

[0070] Example 1: Figure 3 , Fig.11 As shown, in this embodiment, the discharge pipe 3 is provided with a corrugated surface 33, the locking member 51 cooperates with the corrugated surface 33 and the locking member 51 is sleeved with a spring 35, and the spring 35 and the corrugated surface 33 constitute a reset mechanism to make the locking member 51 rotate and reset.

[0071] By setting a corrugated surface on the discharge pipe 3, the locking member 51 cooperates with the corrugated surface and the locking member 51 is sleeved with a spring 35, so that when the locking member 51 is separated from the driving tooth 54, under the action of the spring 35 and the corrugated surface, the locking member 51 can automatically return to a state of engagement with the driving tooth 54, thereby providing a guarantee for the reverse rotation of the discharge pipe 3.

[0072] Embodiment 2: In this embodiment, the reset mechanism is a torsion spring. By setting the reset mechanism as a torsion spring, the locking member 51 can also be reset, and the structure is simple and easy to assemble.

[0073] As a preferred implementation of the present application, Fig.13 As shown, the linkage mechanism 5 also includes an auxiliary transmission member 6; when the discharge pipe 3 rotates to a predetermined position, the auxiliary transmission member 6 and the locking member 51 are synchronously engaged with the driving teeth 54; when the discharge pipe 3 reaches the predetermined position, the auxiliary transmission member 6 and the locking member 51 are synchronously separated from the driving teeth 54.

[0074] By providing the auxiliary transmission member 6, the locking member 51 and the auxiliary transmission member 6 can simultaneously drive the drain pipe 3 to rotate, thereby reducing the load of the locking member 51, avoiding the possibility of damage to the locking member 51 when the locking member 51 is under a high load for a long time, and further ensuring the stability of the transmission between the valve core 4 and the drain pipe 3. In addition, when the drain pipe 3 reaches the predetermined position, the auxiliary transmission member 6 and the locking member 51 are synchronously separated from the driving tooth 54, thereby reducing the wear of the secondary main transmission member, the locking member 51 and the driving tooth 54, extending their service life, and reducing the load of the motor 2, thereby extending the service life of the motor 2.

[0075] As a preferred embodiment of the present application, the linkage mechanism includes an electromagnet; when the discharge pipe 3 rotates to a predetermined position, the electromagnet locks the discharge pipe 3 and the valve core 4; when the discharge pipe 3 reaches the predetermined position, the electromagnet unlocks the discharge pipe 3 and the valve core 4. By setting the linkage mechanism as an electromagnet and other structures, the structure is simple and easy to assemble, and the electromagnet is more stable and reliable when used, avoiding failure after long-term use.

[0076] It should be noted that the present application does not specifically limit how the electromagnet achieves locking and unlocking of the discharge pipe and the valve core in this embodiment, which may be any one of the following embodiments:

[0077] Embodiment 1: In this embodiment, the linkage mechanism further includes a magnet disposed on the discharge pipe, and the electromagnet is disposed on the valve core. When the discharge pipe 3 is rotating to a predetermined position, the electromagnet is energized, and the magnet is adsorbed on the electromagnet to lock the discharge pipe 3 and the valve core 4, so that the valve core 4 can drive the discharge pipe 3 to rotate. When the discharge pipe 3 reaches the predetermined position, the electromagnet is de-energized, and the magnet is separated from the electromagnet, so that the discharge pipe 3 and the valve core 4 are unlocked.

[0078] Embodiment 2: In this embodiment, the linkage mechanism further includes a retractable iron core arranged on the discharge pipe 3, the electromagnet is arranged on the valve core 4, and a positioning hole for the iron core to be inserted is arranged on the electromagnet. When the discharge pipe 3 is rotating to the predetermined position, the electromagnet is energized, and the iron core is inserted into the positioning hole under the action of magnetic force, so that the discharge pipe 3 and the valve core 4 are locked, so that the valve core 4 can drive the discharge pipe 3 to rotate. When the discharge pipe 3 reaches the predetermined position, the electromagnet is de-energized, and the iron core retracts to the original position under the action of its own gravity, so that the discharge pipe 3 and the valve core 4 are unlocked.

It should be pointed out that the combination of the technical solution of any one embodiment with the technical solution of one or more other embodiments is within the protection scope of the present invention.
