Description

Technical Field

[0001] The utility model relates to the technical field of valve cores, in particular to a detachable valve core pull rod clutch structure. Background Art

[0002] In existing beverage preparation or food processing equipment, the valve core structure, as a key component for controlling the flow of fluids (such as water, fruit juice, etc.), directly affects the overall layout, operation convenience, and space utilization efficiency of the equipment. Traditional valve core designs mostly use the method of driving the valve disc to rotate by a motor or driving the valve core to move linearly by a screw to achieve the opening and closing of the channel. However, these designs face some significant limitations in practical applications.

[0003] Firstly, the valve disc rotation structure driven by a motor (as shown in CN203378497U), although it can effectively control the fluid flow direction, due to its rotation mechanism, it often requires a large installation space. Especially when it is necessary to integrate the valve core with components such as a stirring blade on the same side, this design is particularly inconvenient, restricting the miniaturization and multifunctionality of the equipment. Secondly, the valve core linear movement structure driven by a screw (as described in CN215687160 and CN219888755U), although it reduces the space occupation to a certain extent, the direct drive method of the screw means that the movement distance of the valve core is directly related to the stroke of the screw. In order to cover the opening and closing of multiple channels, the screw needs a long movement distance, which usually results in the entire valve control system being installed only on the side of the mixing cup, not only increasing the design complexity but also possibly affecting the overall aesthetics and operation experience of the equipment.

[0004] In addition, there are also certain inconveniences in maintaining and replacing the valve core in the above two designs. The valve disc structure driven by a motor may involve complex circuit connections, while the screw drive structure may be difficult to disassemble quickly due to the tight fit between the screw and the valve core. These factors increase the maintenance cost and operation difficulty of the equipment. Summary of the Utility Model

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a detachable valve core pull rod clutch structure, which reduces the structural complexity and solves the problems of quick disassembly and overlong stroke.

[0006] The technical solution adopted by the utility model to solve its problems is:

[0007] A detachable valve core pull rod clutch structure is used to control the closing or connection of at least two liquid channels, including a valve core body, on which at least two limiting holes are provided; at least two driving rods, which correspond to the limiting holes one by one; a driving rotating shaft, at least two of the driving rods are distributed along the circumferential direction of the driving rotating shaft, a sliding rail is provided on the side wall of the driving rotating shaft, and the end of each driving rod is slidably arranged on the sliding rail; a driving member, which drives the driving rotating shaft to rotate so as to drive the driving rod to move axially along its corresponding limiting hole, for closing or connecting the liquid channel opposite to the driving rod; wherein, at any one time, only one of the driving rods connects its corresponding liquid channel.

[0008] By adopting the above scheme, by distributing the driving rods along the circumferential direction of the driving rotating shaft and combining with the sliding rail to realize the sliding of the driving rods, this design greatly reduces the linear space required by motors or long lead screws in the traditional design. The compact layout of the driving rotating shaft and the sliding rail makes the whole clutch structure more compact, and can effectively solve the problem that the valve core structure occupies a large space and cannot share the same side with components such as mixing blades; the way of combining the pull rod with the clutch can realize the independent opening and closing of multiple channels through the simple operation of the driving member, without complex circuit connections or long-distance moving components, thus simplifying the operation process. At the same time, due to the clear one-to-one correspondence between the driving rod and the limiting hole and the relatively simple structure, the disassembly and replacement of the valve core become easier, reducing the maintenance cost and time.

[0009] Further, the valve core body includes: a valve core outer shell, an accommodation groove is formed inside the valve core outer shell, the limiting holes are located in the accommodation groove, and at least two diversion channels are also provided on the valve core outer shell, and the diversion channels are adjacent to each of the limiting holes; a valve core cover body, which is snap-connected with the valve core outer shell to cover the accommodation groove, and through holes corresponding to the limiting holes one by one are provided on the valve core cover body, and the driving member passes through the through holes and the limiting holes at the same time.

[0010] By adopting the above scheme, the limiting holes are located in the accommodation groove, which is used to limit the axial movement range of the driving rod, ensuring that the driving rod can accurately align with the corresponding liquid channel, so as to realize the closing or connection of the channel.

[0011] Further, one end of the driving rod is provided with a sliding part for sliding along the sliding rail, and the other end is equipped with a sealing plug for closing the liquid channel.

[0012] By adopting the above scheme, the other end of the driving rod is equipped with a sealing plug, which is used to close the liquid channel. When the driving rod moves to a specific position, the sealing plug will accurately insert into the diversion channel, thus realizing the closing of the channel.

[0013] Furthermore, a reset member is sleeved on the driving member, and the reset member is used to apply a force for the sliding portion of the driving member to fit towards the sliding rail.

[0014] By adopting the above solution, after the driving member completes its driving action, the reset member can ensure that the driving member can automatically return to the initial position to prepare for the next action.

[0015] Furthermore, a flow dividing rib is provided on the outer side of the valve core body. The flow dividing rib is located between every two of the limiting holes and is used to enclose an independent flow space between each limiting hole and each diversion channel.

[0016] By adopting the above solution, the fluid between different liquid channels can be separated to prevent them from mixing inside the valve core. This separation effect ensures that each liquid channel can independently control the flow of the fluid therein, thereby improving the fluid control accuracy of the entire valve core.

[0017] Furthermore, a concave assembly groove is provided on the driving rotating shaft, and a flat position is provided in the assembly groove.

[0018] By adopting the above solution, it plays a role of positioning and fixing, which is convenient for connecting the driving device.

[0019] Furthermore, the reset member is a spring. An annular groove is provided on the driving member for abutting against one end of the reset member, and the other end of the reset member abuts against the inner side of the valve core cover body.

[0020] By adopting the above solution, when there is no external force, the spring can ensure that the driving member and its related components are kept in a predetermined position, preventing displacement or loosening caused by factors such as vibration and impact.

[0021] Furthermore, a valve core sleeve for abutting and sealing is also assembled on the side of the valve core housing away from the valve core cover body.

[0022] By adopting the above solution, the valve core sleeve is used to enable the valve core housing to achieve sealed assembly with the food machine after assembly, improve the assembly stability, and avoid shaking.

[0023] Furthermore, the sealing plug includes: a sealing ring; a sealing ring limiting member. The sealing ring limiting member has an assembly hole, and an annular inner groove is provided on the outer side of the sealing ring limiting member. The sealing ring is installed in the annular inner groove, and at least part of the sealing ring protrudes from the annular inner groove; the sealing ring limiting member is detachably connected to the other end of the driving rod.

[0024] By adopting the above solution, the sealing plug can achieve closed sealing with the liquid channel and improve the sealing performance in the closed state.

[0025] Further, the other end of the drive rod is provided with an external thread, and the assembly hole has an internal thread, and the other end of the drive rod is threadedly connected to the assembly hole.

[0026] By adopting the above scheme, the structure between the drive rod and the assembly hole is simple, highly reliable and convenient for disassembly and assembly.

[0027] To sum up, a detachable valve core pull rod clutch structure provided by the present utility model has the following technical effects:

[0028] 1. By circumferentially distributing the drive rods along the drive rotating shaft and combining with the slide rails to realize the sliding of the drive rods, the linear space required by the motor or the long screw in the traditional design is significantly reduced. This compact layout makes the entire clutch structure more compact, and can effectively solve the problem that the valve core structure occupies a large space and cannot share the same side with components such as stirring knives, improving the space utilization efficiency of the equipment.

[0029] 2. By the way of combining the pull rod with the clutch, the independent opening and closing of multiple channels can be realized through simple operation of the driving member. This design does not require complex circuit connections or long-distance moving parts, simplifies the operation process, and improves the operation convenience. The user only needs to control the rotation of the driving member to easily control the opening and closing of each channel.

[0030] 3. Due to the clear one-to-one correspondence between the drive rod and the limiting hole and the relatively simple structure, the disassembly and replacement of the valve core become easier. When maintenance or replacement of the valve core is required, the user can quickly complete these operations without a complex disassembly process, thereby reducing the maintenance cost and time.

[0031] 4. Each drive rod independently controls a liquid channel. At the same time, only one drive rod is connected to its corresponding liquid channel, and the remaining drive rods are all closed to their corresponding liquid channels. This design ensures the accuracy and reliability of channel control, and avoids problems such as liquid leakage or mixing caused by misoperation or failure. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0039] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described and discussed below in conjunction with the drawings of the present utility model. Obviously, what is described here is only a part of the examples of the present utility model, not all examples. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0040] For the convenience of understanding the embodiments of the present utility model, the following will take specific embodiments as examples and make further explanatory descriptions in conjunction with the drawings, and each embodiment does not constitute a limitation to the embodiments of the present utility model.

[0041] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0043] The embodiments of the present utility model are referred to Figures 1 - 6As shown in the figure, a detachable valve core pull rod clutch structure is disclosed, which is used for a soybean milk machine or a wall breaker 1 and can control the closing or communication of at least two liquid channels 11. Specifically, the detachable valve core pull rod clutch structure includes a valve core body 2, at least two driving rods 4, a driving rotating shaft 3 and a driving member 5. At least two limiting holes 212 are provided on the valve core body 2, and the driving rods 4 correspond to the limiting holes 212 one by one. At least two of the driving rods 4 are circumferentially distributed along the driving rotating shaft 3. A slide rail 31 is provided on the side wall of the driving rotating shaft 3. The end of each driving rod 4 is slidably disposed on the slide rail 31. The driving rod 4 slides along the slide rail 31. The driving member 5 drives the driving rotating shaft 3 to rotate, so as to drive the driving rod 4 to perform an axial movement along its corresponding limiting hole 212, for closing or communicating the liquid channel 11 opposite to the driving rod 4. It should be noted that at any time, only one of the driving rods 4 communicates with its corresponding liquid channel 11, and the remaining driving rods 4 close their corresponding liquid channels 11. In this Embodiment 1, two driving rods 4, two limiting holes 212 and two liquid channels 11 are provided, and the driving rotating shaft 3 is located between the two driving rods 4. The two driving rods 4 interact with the slide rail 31 on the side wall of the driving rotating shaft 3 to achieve the driving effect of the driving rod 4 along its axis, and further realize the control of the communication and closing of the two liquid channels 11. By circumferentially distributing the driving rods 4 along the driving rotating shaft 3 and combining with the slide rail 31 to realize the sliding of the driving rods 4, this design greatly reduces the linear space required for the motor or the long screw in the traditional design. The compact layout of the driving rotating shaft 3 and the slide rail 31 makes the entire clutch structure more compact, and can effectively solve the problem that the valve core structure occupies a large space and cannot share the same side with components such as the stirring knife; the way of combining the pull rod with the clutch can realize the independent opening and closing of multiple channels through the simple operation of the driving member 5, without complex circuit connections or long-distance moving components, thus simplifying the operation process. At the same time, due to the clear one-to-one correspondence between the driving rod 4 and the limiting hole 212 and the relatively simple structure, the disassembly and replacement of the valve core become easier, reducing the maintenance cost and time.

[0044] In a specific embodiment, the valve core body 2 includes a valve core housing 21, a valve core cover 22, and a valve core sleeve 24. The valve core sleeve 24 is located on the side of the valve core housing 21 away from the valve core cover 22. An accommodation groove 211 is formed in the valve core housing 21, and the limit hole 212 is located in the accommodation groove 211. At least two diversion channels 213 are further provided on the valve core housing 21, and the diversion channels 213 are adjacent to each limit hole 212. The valve core cover 22 is snap-connected to the valve core housing 21 to cover the accommodation groove 211. A through hole 221 corresponding to the limit hole 212 one by one is provided on the valve core cover 22, and the driving member 5 passes through the through hole 221 and the limit hole 212 at the same time. The limit hole 212 is located in the accommodation groove 211 and is used to limit the axial movement range of the driving rod 4, ensuring that the driving rod 4 can accurately align with the corresponding liquid channel 11, so as to realize the closing or connection of the channel. In this Embodiment 1, there are two accommodation grooves 211, providing moving spaces for the two driving rods 4 respectively.

[0045] In order to facilitate the driving member 5 to be smoother and have a reset effect, in some embodiments, a reset member 6 is sleeved on the driving member 5, and the reset member 6 is used to provide a force for the sliding part 41 of the driving member 5 to fit towards the slide rail 31. When the driving member 5 completes its driving action, the reset member 6 can ensure that the driving member 5 can automatically return to the initial position to prepare for the next action. In this Embodiment 1, the reset key is a spring, and the spring is limited in the accommodation groove 211. An annular groove 43 for abutting against one end of the reset member 6 is provided on the driving member 5, and the other end of the reset member 6 abuts against the inner side of the valve core cover 22. With this setting, when there is no external force, the spring can ensure that the driving member 5 and its related components are kept in a predetermined position, preventing displacement or loosening caused by factors such as vibration and impact.

[0046] It should be noted that in other embodiments, a tension spring or other elastic materials can also be used as the reset key, and this embodiment does not make specific limitations.

[0047] In some embodiments, the driving rotating shaft 3 is usually assembled and connected to the motor. Therefore, a connection structure capable of driving needs to be provided for the two. Specifically, a concave assembly groove 32 is provided on the driving rotating shaft 3, and a flat position 321 is provided in the assembly groove 32. The flat position 321 plays a role in positioning and fixing, facilitating the driving effect after the motor is connected. Preferably, an intermediate member can also be provided between the motor and the driving rotating shaft 3 to avoid the problem of direct contact wear between the two.

[0048] In order to enable the driving rotating shaft 3 to interact with the driving rod 4 smoothly, specifically, one end of the driving rod 4 is provided with a sliding portion 41 for sliding along the slide rail 31. In the first embodiment, the sliding portion 41 is a lip plate, which can always abut against the slide rail 31 under the action of the reset key, so as to change the position of the driving member 5 following the displacement change of the slide rail 31. Since there are two driving rods 4 in this embodiment, the slide rail 31 can be set to a shape similar to a corrugation, or a ramp shape with one side higher than the other side or a toothed shape. When the driving rotating shaft 3 rotates in place, the two driving rods 4 can be kept in different states, always making one of the two liquid channels 11 communicate and the other close.

[0049] In order to improve the sealing performance between the driving rod 4 and the liquid channel 11 in the closed state, a sealing plug 42 for closing the liquid channel 11 is assembled at the other end of the driving rod 4. The sealing plug 42 includes a sealing ring 421 and a sealing ring limiting member 422. The sealing ring limiting member 422 has an assembly hole 423, and an annular inner groove 424 is arranged on the outer side of the sealing ring limiting member 422. The sealing ring 421 is installed in the annular inner groove 424, and at least part of the sealing ring 421 protrudes from the annular inner groove 424; the sealing ring limiting member 422 is detachably connected to the other end of the driving rod 4, and the sealing plug 42 can achieve closed sealing with the liquid channel 11, improving the sealing performance in the closed state. In the first embodiment, the other end of the driving rod 4 is provided with an external thread, and the assembly hole 423 has an internal thread. The other end of the driving rod 4 is threadedly connected to the assembly hole 423. With this setting, the structure between the driving rod 4 and the assembly hole 423 is simple, has high reliability and is convenient for disassembly and assembly, which is more conducive to replacing accessories.

[0050] In some embodiments, in order to prevent each liquid channel 11 from contacting each other during the process of reaching their respective diversion channels 213, a flow dividing rib 23 is arranged on the outer side of the valve core body 2. The flow dividing rib 23 is located between every two limiting holes 212 and is used to enclose an independent flow space between each limiting hole 212 and each diversion channel 213, which can separate the fluids in different liquid channels 11 and prevent them from mixing inside the valve core. This separating effect ensures that each liquid channel 11 can independently control the flow of the fluid therein, thereby improving the fluid control accuracy of the entire valve core.

[0051] In summary, the detachable valve core pull rod clutch structure provided by the present utility model has the following technical effects:

[0052] 1. By distributing the driving rods 4 along the circumferential direction of the driving rotating shaft 3 and combining with the sliding rail 31 to achieve the sliding of the driving rods 4, the linear space required by the motor or the long screw in the traditional design is significantly reduced. This compact layout makes the entire clutch structure more compact, effectively solving the problem that the spool structure occupies a large space and cannot share the same side with components such as the stirring blade, and improving the space utilization efficiency of the equipment.

[0053] 2. Through the way of combining the pull rod with the clutch, the independent opening and closing of multiple channels can be achieved through the simple operation of the driving part 5. This design does not require complex circuit connections or long-distance moving parts, simplifies the operation process, and improves the operation convenience. The user only needs to control the rotation of the driving part 5 to easily control the opening and closing of each channel.

[0054] 3. Due to the clear one-to-one correspondence between the driving rod 4 and the limiting hole 212 and the relatively simple structure, the disassembly and replacement of the spool become easier. When maintenance or replacement of the spool is required, the user can complete these operations quickly without a complex disassembly process, thus reducing the maintenance cost and time.

[0055] 4. Each driving rod 4 independently controls a liquid channel 11. At the same time, only one driving rod 4 is connected to its corresponding liquid channel 11, and the remaining driving rods 4 are all closed to their corresponding liquid channels 11. This design ensures the accuracy and reliability of channel control, avoiding problems such as liquid leakage or mixing caused by misoperation or failure.

[0056] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
