Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a noodle maker with reliable limit. Background Art

[0002] Existing noodle makers generally include a machine base, a kneading cup installed above the machine base, and a cup cover covering the kneading cup. A motor is provided in the machine base, and a stirring member driven by the motor is provided in the kneading cup. The stirring member is vertically arranged in the kneading cup and rotates to knead the dough.

[0003] In traditional noodle makers, the cup cover and the kneading cup are mostly fastened by rotation. For example, a clamping rib is provided on the kneading cup, and a rotating groove is provided on the cup cover. The clamping rib rotates and engages in the rotating groove to fasten the cup cover and the kneading cup. This screwing method is convenient to operate. However, since the stirring member is vertically arranged in the kneading cup, the upper end of the stirring member is in limit cooperation with the cup cover. In the later stage of the kneading process, the dough will continuously offset relative to the center of gravity axis of the kneading cup in the kneading cup, resulting in a large load on the stirring member, causing the cup cover to shake, and the clamping rib is easily screwed out of the rotating groove, causing problems such as flour spilling; in addition, for a noodle maker in which the motor simultaneously drives the pressing screw, when the stirring member rotates in reverse, the cup cover and the kneading cup are easily unscrewed, resulting in the risk of the cup cover loosening and flour spilling.

[0004] The prior art also discloses a food processor, including a barrel body and a cover body covering the barrel body; a clamping portion is provided on the barrel body, and an elastic locking structure for cooperating with the clamping portion is provided on the cover body. The elastic locking structure can move horizontally in a direction towards or away from the cover body, so that the elastic locking structure engages or disengages with the clamping portion. Specifically, a receiving groove is provided on the cover body, and the elastic locking structure is arranged in the receiving groove, and the guiding is realized by means of a slide rail and a slide groove between the side wall of the receiving groove and the edge of the elastic locking structure, so as to realize the smooth movement of the elastic locking structure. However, this installation method requires a relatively high matching gap between the slide rail and the slide groove. If the gap is too large, it is easy to cause the locking member to deflect when sliding. If the gap is too small, it is easy to cause unsmooth sliding. In short, the user's experience of opening the cover is not good; in addition, in order to realize the movement stop position of the elastic locking structure, the prior art only directly installs a screw through the cover body, and the elastic locking structure is blocked at two limit positions by the screw. However, usually, the elastic locking structure and the cover body are both plastic parts. After the elastic locking structure is directly blocked and limited by the screw for a long time, the screw will cause serious wear to the elastic locking structure and the cooperation between the screw and the cup cover will become loose, resulting in the limit failure between the cover body and the barrel body. Summary of the Utility Model

[0005] The utility model provides a noodle machine with reliable limit. By optimizing the limit mode between the cup cover and the dough mixing cup, on the basis of realizing the reliable cooperation between the cup cover and the dough mixing cup and not being easily unscrewed, the problem that the stop modes of the elastic buckle at two extreme positions are seriously worn, resulting in the limit failure between the cup cover and the dough mixing cup, is further solved, and the opening feeling of the cover is improved at the same time.

[0006] The utility model provides a noodle machine with reliable limit, which comprises a machine base, a dough mixing cup installed on the machine base, and a cup cover covered above the dough mixing cup. The cup cover is provided with an elastically movable buckle that can move horizontally and a receiving groove for installing the elastically movable buckle. A buckling part is arranged on the side wall of the dough mixing cup. A limiting block protruding upward is fixedly arranged in the receiving groove. The elastically movable buckle is provided with a limiting groove for the limiting block to extend into. The elastically movable buckle slides along the limiting block through the limiting groove, and both ends of the limiting block along the moving direction of the elastically movable buckle are respectively in stop cooperation with the groove walls of the limiting groove, so that the elastically movable buckle moves between a first position where it is buckled with the buckling part and a second position where it is separated from the buckling part.

[0007] A noodle machine with reliable limit provided by the utility model realizes reliable cooperation between the cup cover and the noodle-making cup by arranging an elastically buckled part that moves horizontally on the cup cover and a buckling part on the side wall of the noodle-making cup, and using the elastic buckle to be buckled with the buckling part. After the user presses it, the elastic buckle moves horizontally to disengage from the buckling part. During the processing of the noodle machine, after the elastic buckle and the buckling part are buckled in place, both of them are in a state of being positioned and locked in both the axial direction and the circumferential direction of the noodle-making cup. Therefore, the cup cover and the noodle-making cup will not separate, effectively preventing flour from spilling out. By arranging a limiting block in the accommodating groove and providing a limiting groove for the limiting block to extend into the elastic buckle, the elastic buckle slides along the limiting block through the limiting groove. The guiding effect is realized by the cooperation of the separately arranged limiting block and the limiting groove in the accommodating groove. Compared with the traditional method of guiding the sliding of the edge of the elastic buckle and the groove wall of the accommodating groove, the requirement for the matching gap between the elastic buckle and the accommodating groove can be reduced. Therefore, during the process of the user pressing the elastic buckle, the problems of being too tight and stuck or too loose and swaying in cooperation can be avoided. On the premise of realizing the smooth movement of the elastic buckle, it is beneficial to improve the operation feel of the user. At the same time, both ends of the limiting block along the moving direction of the elastic buckle are in stop cooperation with the groove wall of the limiting groove, so that the elastic buckle moves between a first position where it is engaged with the buckling part and a second position where it is disengaged from the buckling part. That is, the limiting block not only guides the movement of the elastic buckle but also plays a stop role, enabling the elastic buckle to stay at the two extreme positions of the first position and the second position. There is a certain stop mating surface between the limiting block and the limiting groove. Compared with the traditional method of directly stopping with an exposed screw, the wear caused by repeated collisions between the two is greatly reduced, thereby ensuring the effective movement and stop of the elastic buckle to ensure the effective engagement between the elastic buckle and the buckling part. In summary, for the noodle machine with reliable limit provided by the utility model, the engagement between the cup cover and the noodle-making cup is more reliable, more durable and effective, and the feeling of opening the cover is better.

[0008] In a preferred embodiment, the bottom of the accommodating groove sinks to form a sunken platform, the limiting block is detachably installed on the sunken platform, and a convex wall that horizontally blocks above the sunken platform is further arranged in the accommodating groove, and the convex wall is pressed against the limiting block to limit the limiting block between the convex wall and the sunken platform.

[0009] By sinking the bottom of the accommodating groove to form a sunken platform and detachably installing the limiting block on the sunken platform, it is convenient for the independent manufacturing of the cup cover and the limiting block, as well as the disassembly and replacement of the limiting block. Using the convex wall to press the limiting block, during the process of assembling the limiting block and the cup cover, the convex wall and the sunken platform limit the limiting block, eliminating the need for the assembly worker to manually press the limit. The assembly is more convenient, and the assembly position is accurate, preventing situations such as displacement caused by the worker's manual pressing, improving the assembly accuracy and efficiency. After assembly, the limiting block and the limiting groove achieve effective guiding cooperation to realize the effective sliding of the elastic buckle in the accommodating groove.

[0010] In a preferred embodiment, the limiting block and the accommodating groove are locked by fasteners;

[0011] Alternatively, the limiting block and the accommodating groove are fixed by snap members.

[0012] The locking between the limiting block and the accommodating groove by fasteners or snap members can achieve reliable fixation and convenient assembly during the assembly process of the two, facilitate the independent manufacturing of the cup lid and the limiting block, and facilitate the disassembly and replacement of the limiting block, so as to achieve reliable and lasting engagement between the cup lid and the dough mixing cup.

[0013] In a preferred embodiment, a limiting platform is formed by the depression of the top edge of the limiting block, and the convex wall is pressed above the limiting platform.

[0014] By forming a limiting platform by the depression of the top edge of the limiting block, a horizontal table surface and a vertical surface are formed. The convex wall presses above the table surface of the limiting platform to vertically limit the limiting platform. At the same time, the vertical surface of the limiting platform and the end of the convex wall form a lateral limit. Therefore, when installing the limiting block, the worker only needs to vertically limit the limiting platform by means of the convex wall, and then apply force in the lateral direction to make the vertical surfaces of the limiting block and the limiting platform abut. The assembly is more convenient and labor-saving, and at the same time, the assembly accuracy and efficiency can be improved. In addition, by forming the limiting platform in a depressed manner, the overall height after the cooperation of the convex wall and the limiting block is reduced, which is beneficial to reducing the size of the cup lid and making the space layout compact and reasonable.

[0015] In a preferred embodiment, the limiting block is supported on the sunken platform, the convex wall is not higher than the top surface of the limiting block, and a pressing tongue is convexly provided on the side of the limiting block and pressed below the convex wall;

[0016] Alternatively, the limiting block is supported on the sunken platform, the convex wall is higher than the limiting block and pressed against the top end of the limiting block.

[0017] By the convex wall not being higher than the top surface of the limiting block, and using the convex wall to press the pressing tongue, not only can the axial pre-positioning of the limiting block be realized, but also the overall height can be reduced, which is beneficial to reducing the size of the cup lid and making the space layout compact and reasonable. By adopting the method that the convex wall is higher than the limiting block and pressed against the top end of the limiting block, the design requirements for the limiting block are reduced, which is convenient for processing and manufacturing and reduces the production cost. No matter which of the above pressing methods is adopted, the limiting block can be detachably installed on the cup lid to facilitate the independent manufacturing of the cup lid and the limiting block, and facilitate the disassembly and replacement of the limiting block. At the same time, the positioning is convenient and the installation is convenient.

[0018] In a preferred embodiment, the side wall of the limiting block is provided with convex ribs extending vertically, and the inner side wall of the limiting groove is in sliding fit with the convex ribs along the elastic snap movement direction.

[0019] By providing vertically extending ribs on the side wall of the limit block, the inner side wall of the limit groove and the ribs are in sliding fit along the moving direction (transverse direction) of the elastic buckle. That is, the sliding fit area between the limit block and the limit groove is reduced by the ribs, thereby reducing the friction force during the sliding process and making the elastic buckle move more smoothly during the movement.

[0020] In a preferred embodiment, the outer side wall of the limit block and the inner side wall of the limit groove are in sliding fit along the moving direction of the elastic buckle;

[0021] Alternatively, one of the limit block and the limit groove is provided with a protrusion, and the other is provided with a sliding groove, and the protrusion slides in the sliding groove.

[0022] On the basis that the limit block itself forms a precise guide for the movement of the elastic buckle through the limit groove, a guiding mechanism is formed by the sliding fit between the outer side wall of the limit block and the inner side wall of the limit groove along the moving direction of the elastic buckle. Alternatively, a guiding mechanism is formed by the protrusion and the sliding groove, achieving a double guiding effect, which can provide precise guidance for the movement of the elastic buckle, reduce the deviation during the movement process, and ensure that the elastic buckle moves in a predetermined direction to effectively cooperate with the buckling part. At the same time, the precise guidance can reduce the wear degree between the limit block and the limit groove, reduce unnecessary friction and collision between the elastic buckle and the accommodation groove, extend the service life of the elastic buckle, and improve the user operation feel.

[0023] In a preferred embodiment, the inner side wall of the accommodation groove is provided with a first limit rib, and the edge of the elastic buckle is provided with a second limit rib, and the first limit rib is pressed above the second limit rib;

[0024] By pressing the first limit rib above the second limit rib, it can provide an auxiliary guiding effect for the horizontal movement of the elastic buckle and achieve smooth sliding of the elastic buckle.

[0025] Alternatively, the elastic buckle includes a body and a spring. A positioning post extending horizontally is provided in the accommodation groove. The spring is sleeved on the positioning post and abuts against the body, and the center lines of the positioning post, the spring and the body are located in the same vertical plane.

[0026] The elastic buckle includes a body and a spring. A positioning post is arranged in the accommodation groove so that the spring is sleeved on the positioning post and abuts against the body. In the natural state, the spring holds the body at a first position where it engages with the fastening part. When a user applies force to compress the spring, the body can be disengaged from the fastening part, thereby realizing the effective cooperation between the body and the fastening part, and achieving the fastening and detachment between the cup lid and the dough mixing cup. By aligning the center lines of the positioning post, the spring, and the body in the same vertical plane, even when using one spring, the body can still accurately slide in the preset direction to achieve effective engagement, simplifying the overall structure of the elastic buckle. At the same time, by aligning the center lines of the positioning post, the spring, and the body in the same vertical plane, it effectively prevents the spring from swaying during the release or compression process, making the movement of the elastic buckle smoother.

[0027] In a preferred embodiment, the elastic buckle includes a spring, a vertically arranged pressing plate, a horizontal plate bent from the bottom end of the pressing plate, and a tongue located at one end of the horizontal plate away from the pressing plate. The accommodation groove includes a first groove for accommodating the horizontal plate and a second groove for vertically limiting the pressing plate. The spring abuts between the second groove and the pressing plate.

[0028] By setting the elastic buckle as a pressing plate and a horizontal plate bent from the bottom end of the pressing plate, it can not only satisfy the cooperation between the tongue and the fastening part near the edge of the cup lid, but also make the pressing plate close to the middle of the cup lid. The outer diameter of the pressing plate is smaller, reducing the difficulty for the user to operate the pressing plate with one hand and improving the user's operation feel, making the operation easier.

[0029] In a preferred embodiment, the pressing plate slides along the depth direction of the second groove. The depth W1 of the second groove, the groove width W2 of the limiting groove along the moving direction of the elastic buckle, and the width W3 of the limiting block along the moving direction of the elastic buckle satisfy: W1 > W2 - W3.

[0030] Satisfying W1 > W2 - W3 means that along the moving direction of the elastic buckle, the limitation between the elastic buckle and the cup lid is only achieved through the limiting groove and the limiting block, rather than through the second groove and the elastic buckle to achieve stopping, thereby preventing the situation of excessive limitation and affecting the user's operation.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.

[0049] As Figures 1 - 9 shown, in one embodiment of the present utility model, a noodle machine with reliable limit is provided, including a machine base 10, a kneading cup 20 installed on the machine base 10, and a cup cover 30 covering the upper part of the kneading cup 20. The cup cover 30 is provided with an elastically movable snap 40 and a receiving groove 31 for installing the elastically movable snap 40. A fastening portion 21 is provided on the side wall of the kneading cup 20. As Figure 4As shown, a limiting block 50 protruding upward is fixedly provided in the accommodating groove 31. The elastic buckle 40 is provided with a limiting groove 401 for the limiting block 50 to extend into. The elastic buckle 40 slides along the limiting block 50 through the limiting groove 401, and both ends of the limiting block 50 in the moving direction of the elastic buckle 40 are respectively in stop cooperation with the groove walls of the limiting groove 401, so that the elastic buckle 40 moves between a first position where it is engaged with the engaging portion 21 and a second position where it is disengaged from the engaging portion 21. As Figure 4 and Figure 6 show the state where the elastic buckle is in the first position; as Figure 5 and Figure 7 show the state where the elastic buckle is in the second position. In Figure 5 、 7 , the arrow indicates the direction in which the corresponding elastic buckle slides from the first position to the second position.

[0050] A noodle machine with reliable limit provided by the utility model realizes the reliable cooperation between the cup cover 30 and the dough mixing cup 20 by arranging an elastically buckling part 40 moving horizontally on the cup cover 30 and a buckling part 21 on the side wall of the dough mixing cup 20, and making the elastically buckling part 40 be buckled with the buckling part 21. After the user presses, the elastically buckling part 40 moves horizontally until it disengages from the buckling part 21. During the processing of the noodle machine, after the elastically buckling part and the buckling part are buckled in place, they are in a state of being positioned and locked both axially and circumferentially of the dough mixing cup. Therefore, the cup cover 30 and the dough mixing cup 20 will not disengage, effectively preventing the flour from spilling out. By arranging a limiting block 50 in the accommodating groove 31 and providing a limiting groove 401 in the elastically buckling part 40 for the limiting block 50 to extend into, the elastically buckling part 40 slides along the limiting block 50 through the limiting groove 401. The guiding effect is realized by the cooperation of the separately arranged limiting block 50 and the limiting groove 401 in the accommodating groove 31. Compared with the traditional way of guiding the sliding of the edge of the elastically buckling part 40 and the groove wall of the accommodating groove 31, the requirement for the matching gap between the elastically buckling part 40 and the accommodating groove 31 can be reduced. Therefore, during the process of the user pressing the elastically buckling part 40, problems such as being too tight and stuck or too loose and swaying in cooperation can be avoided. Thus, on the premise of realizing the smooth movement of the elastically buckling part 40, it is beneficial to improve the operation feel of the user. At the same time, both ends of the limiting block 50 along the moving direction of the elastically buckling part 40 are in stop cooperation with the groove wall of the limiting groove 401, so that the elastically buckling part 40 moves between a first position where it is engaged with the buckling part 21 and a second position where it disengages from the buckling part 21. That is, the limiting block 50 not only guides the movement of the elastically buckling part 40 but also plays a stop role, enabling the elastically buckling part 40 to stay at the two extreme positions of the first position and the second position. There is a certain stop mating surface between the limiting block 50 and the limiting groove 401. Compared with the traditional way of directly stopping with an exposed screw, the wear caused by repeated collisions between the two is greatly reduced, thereby ensuring the effective movement and stop of the elastically buckling part 40 to ensure the effective engagement between the elastically buckling part 40 and the buckling part 21. In summary, for the noodle machine with reliable limit provided by the utility model, the engagement between the cup cover 30 and the dough mixing cup 20 is more reliable, more durable and effective, and the feel of opening the cover is better.

[0051] It should be noted that the utility model does not limit the form of the limiting block 50 and the way of fixing the limiting block 50 to the accommodating groove 31 on the cup cover 30. For example:

[0052] Embodiment 1, as Figures 1 - 9 shown, the limiting block 50 is detachably installed on the cup cover 30, combined with Figure 8As shown, a sunken platform 32 is formed by the bottom of the accommodating groove 31 sinking. The limiting block 50 is detachably installed on the sunken platform 32. A convex wall 33 that horizontally shields above the sunken platform 32 is also provided in the accommodating groove 31. The convex wall 33 is press-fitted on the limiting block 50 so that the limiting block 50 is limited between the convex wall 33 and the sunken platform 32. Specifically, the sunken platform 32 extends to the edge of the cup lid 30 to form an opening for the horizontal installation of the limiting block 50. Preferably, a limiting platform 51 is formed by the top edge of the limiting block 50 being recessed, and the convex wall 33 is press-fitted above the limiting platform 51. Preferably, the limiting block 50 and the accommodating groove 31 are locked by a fastener 61.

[0053] Combined Figure 8 with Figure 9 , the assembly process among the limiting block 50, the elastic buckle 40, and the cup lid 30 is as follows: First, place the limiting block 50 in the limiting groove 401 of the elastic buckle 40 to form an assembly. Horizontally slide this assembly into the accommodating groove 31 from the opening on the side of the cup lid. During the sliding process, the limiting block 50 is clamped between the convex wall 33 and the sunken platform 32 to achieve vertical limitation by means of the convex wall 33 and the sunken platform 32. Then, the worker passes a fastener 61 such as a screw through the cup lid 30 from bottom to top and locks it to the limiting block 50 to complete the assembly of the limiting block, the elastic buckle, and the cup lid. Refer to Figure 10 .

[0054] In this embodiment, by forming a sunken platform 32 by the bottom of the accommodating groove 31 sinking, the limiting block 50 is detachably installed on the sunken platform 32, which is convenient for the independent manufacturing of the cup lid 30 and the limiting block 50, and for the replacement of the limiting block 50. By using the convex wall 33 to press-fit and limit the limiting block 50, during the assembly process of the limiting block 50 and the cup lid 30, the convex wall 33 and the sunken platform 32 limit the limiting block 50, eliminating the need for the assembly worker to manually press for limitation. The assembly is more convenient, and the assembly position is accurate, preventing situations such as displacement caused by the worker's manual pressing, improving the assembly accuracy and efficiency. After assembly, the limiting block 50 and the limiting groove 401 achieve effective guiding cooperation to enable the effective sliding of the elastic buckle 40 within the accommodating groove 31. By forming a limiting platform 51 by the top edge of the limiting block 50 being recessed, a horizontal tabletop and a vertical surface are formed. The convex wall 33 is used to press-fit above the tabletop of the limiting platform 51 to vertically limit the limiting platform 51. At the same time, the vertical surface of the limiting platform 51 and the end of the convex wall 33 form a horizontal limit. Thus, when the worker installs the limiting block 50, after vertically limiting the limiting platform 51 with the help of the convex wall 33, only applying force in the horizontal direction to make the vertical surfaces of the limiting block 50 and the limiting platform 51 abut is required. The assembly is more convenient and labor-saving, and can also improve the assembly accuracy and efficiency. In addition, by forming the limiting platform 51 in a recessed manner, the overall height after the convex wall 33 and the limiting block 50 are combined is reduced, which is beneficial for reducing the size of the cup lid 30 and making the spatial layout compact and reasonable.

[0055] Of course, it should be noted that in order to achieve the vertical limit of the limiting block 50 by the convex wall 33, in other embodiments, the convex wall 33 may not be higher than the top surface of the limiting block 50, and a pressing tongue is convexly provided on the side of the limiting block 50 and pressed under the convex wall 33; alternatively, the limiting block 50 is supported on the sunken platform 32, the convex wall 33 is higher than the limiting block 50 and pressed against the top end of the limiting block 50.

[0056] By making the convex wall 33 not higher than the top surface of the limiting block 50 and using the convex wall 33 to press the pressing tongue, not only can the axial pre-positioning of the limiting block 50 be achieved, but also the overall height can be reduced, which is beneficial to reducing the size of the cup lid 30 and making the spatial layout compact and reasonable. By adopting the method that the convex wall 33 is higher than the limiting block 50 and pressed against the top end of the limiting block 50, the design requirements for the limiting block 50 are reduced, which is convenient for processing and manufacturing and reduces the production cost. No matter which of the above pressing methods is adopted, the limiting block 50 can be detachably installed on the cup lid 30 to facilitate the independent manufacturing of the cup lid 30 and the limiting block 50, as well as the replacement of the limiting block 50, and at the same time, the positioning is convenient and the installation is convenient.

[0057] As Figure 8 shown, in this embodiment, a first limiting rib 310 is provided on the inner side wall of the accommodating groove 31, a second limiting rib 402 is provided on the edge of the elastic buckle 40, and the first limiting rib 310 is pressed above the second limiting rib 402; by pressing the first limiting rib 310 above the second limiting rib 402, it can provide an auxiliary guiding effect for the horizontal movement of the elastic buckle 40 and realize the smooth sliding of the elastic buckle 40. At the same time, during the assembly of the elastic buckle, the first limiting rib 310 and the second limiting rib 402 achieve the guiding effect of installation.

[0058] In this embodiment, as Figure 8 shown, the elastic buckle 40 includes a body and a spring 41. A positioning post 313 extending horizontally is provided in the accommodating groove 31. The spring 41 is sleeved on the positioning post 313 and abuts against the body. The center line X of the positioning post, the spring 41 and the body is located in the same vertical plane P. More preferably, the elastic buckle 40 includes a spring 41, a vertically arranged pressing plate 42, a horizontal plate 43 bent from the bottom end of the pressing plate 42, and a locking tongue 44 located at one end of the horizontal plate 43 away from the pressing plate 42. Among them, the pressing plate 42, the horizontal plate 43 and the locking tongue 44 form the above-mentioned body. The accommodating groove 31 includes a first groove 311 for accommodating the horizontal plate 43 and a second groove 312 for vertically limiting the pressing plate 42. The spring 41 abuts between the second groove 312 and the pressing plate 42. Preferably, two elastic buckles 40 are symmetrically arranged, and the user can pinch the pressing plate of the body with fingers to compress the spring to realize the movement of the elastic buckle.

[0059] More preferably, in combination with Figure 3 、 6, 7. The pressing plate 42 slides along the depth direction of the second groove 312. The depth W1 of the second groove 312, the groove width W2 of the limiting groove 401 along the moving direction of the elastic buckle 40, and the width W3 of the limiting block 50 along the moving direction of the elastic buckle 40 satisfy: W1 > W2 - W3. In fact, W2 - W3 is the sliding stroke of the elastic buckle between the first position and the second position.

[0060] The elastic buckle 40 includes a body and a spring 41. A positioning post is arranged in the accommodating groove 31 so that the spring 41 is sleeved on the positioning post and abuts against the body. In the natural state, the spring 41 keeps the body in the first position where it is engaged with the engaging portion 21. When a user applies force to compress the spring 41, the body can be disengaged from the engaging portion 21, thereby realizing the effective cooperation between the body and the engaging portion 21, and realizing the fastening and detachment of the cup lid 30 and the dough mixing cup 20. By making the center lines of the positioning post, the spring 41, and the body lie in the same vertical plane, even when using one spring 41, the body can still accurately slide in the preset direction to achieve effective engagement, simplifying the overall structure of the elastic buckle 40. At the same time, by making the center lines of the positioning post, the spring, and the body lie in the same vertical plane, it effectively prevents the spring from swaying during the release or compression process, making the movement of the elastic buckle smoother.

[0061] By setting the elastic buckle 40 as the pressing plate 42 and the cross plate 43 bent from the bottom end of the pressing plate 42, it can not only meet the requirement that the tongue 44 approaches the edge of the cup lid 30 to cooperate with the engaging portion 21, but also make the pressing plate 42 approach the middle of the cup lid 30. The outer diameter of the pressing plate 42 is smaller, reducing the difficulty for the user to operate the pressing plate 42 with one hand, improving the user's operation feel, and making the operation easy.

[0062] Satisfying W1 > W2 - W3 means that along the moving direction of the elastic buckle 40, the limitation between the elastic buckle 40 and the cup lid 30 is only achieved through the limiting groove 401 and the limiting block 50, and the second groove 312 and the elastic buckle 40 are avoided to achieve stopping, thereby preventing excessive limitation and affecting the user's operation.

[0063] It can be understood that the specific structure of the elastic buckle 40 in this embodiment is still applicable to other embodiments.

[0064] As Figure 6 , 7 , as shown in 8, in this embodiment, the limiting groove 401 is a closed-loop groove formed around the periphery of the limiting block 50. In fact, the limiting groove can also be provided with a notch. For example, the limiting groove includes a first rib and a second rib arranged oppositely. The first rib abuts against the limiting block to make the elastic buckle in the first position, and the second rib abuts against the limiting block to make the elastic buckle in the second position, and a notch is formed between the first rib and the second rib.

[0065] In addition, it should be noted that, as Figure 1 shown, in this embodiment, the noodle machine is an integrated noodle machine for dough kneading and noodle pressing, including a dough kneading member 70 and a noodle pressing assembly 80 disposed in the dough kneading cup; in addition, in this application, the dough kneading member 70 can be optionally arranged vertically or horizontally. Of course, the noodle machine provided by the present utility model can also be a dough kneading machine only provided with a dough kneading member.

[0066] Embodiment 2, as Figure 10 、 11 shown, different from Embodiment 1, in this embodiment, the fastener 61 is omitted, and the limiting block 50 and the accommodating groove 31 are fixed by a snap 62 member. Specifically, referring to Figure 11 , the accommodating groove extends to the edge of the cup lid to form an opening, a snap 62 is arranged at the inner end of the limiting block, and a buckle position corresponding to the snap is arranged in the accommodating groove, and the limiting block is horizontally snapped into the accommodating groove from the opening.

[0067] Actually, whether the limiting block 50 and the accommodating groove 31 are locked by the fastener 61 in Embodiment 1 or fixed by the snap 62 member in Embodiment 2, reliable fixation and convenient assembly can be achieved during the assembly process of the limiting block 50 and the accommodating groove 31, which is convenient for the independent manufacturing of the cup lid 30 and the limiting block 50, and convenient for the disassembly and replacement of the limiting block 50, so as to achieve reliable and lasting clamping between the cup lid 30 and the dough kneading cup 20.

[0068] Of course, it can be understood that, in order to strengthen the fixation between the limiting block 50 and the cup lid 30, the above-mentioned method of locking the limiting block 50 and the accommodating groove 31 by the fastener 61 or fixing by the snap 62 member can be applied to other embodiments in which the limiting block 50 and the cup lid 30 are separately fixed.

[0069] Embodiment 3, the limiting block 50 and the cup lid 30 are integrally formed, and the limiting block 50 integrally protrudes in the accommodating groove 31. This embodiment omits the separate installation of the limiting block 50 and simplifies the structure of the cup lid 30.

[0070] It should be noted that in the present utility model, the guiding manner in which the elastic buckle 40 slides along the limiting block 50 through the limiting groove 401 can be realized by directly sliding and matching the outer side wall of the limiting block 50 and the inner side wall of the limiting groove 401 along the moving direction of the elastic buckle 40. Of course, in a more preferred embodiment, for example:

[0071] Embodiment 4, referring to Figure 8 shown, the side wall of the limiting block 50 is provided with a vertically extending rib 52, and the inner side wall of the limiting groove 401 slides and cooperates with the rib along the moving direction of the elastic buckle 40.

[0072] By providing vertically extending ribs on the side wall of the limit block 50, the inner side wall of the limit groove 401 and the ribs are in sliding fit along the moving direction (transverse direction) of the elastic buckle 40. That is, the sliding fit area between the limit block 50 and the limit groove 401 is reduced by the ribs, thereby reducing the frictional force during the sliding process and making the movement of the elastic buckle 40 smoother.

[0073] Embodiment 5. To better realize the guiding between the limit block 50 and the limit groove 401, a convex block is provided on the side of the limit block 50, and a sliding groove is provided on the groove wall of the limit groove 401. The convex block slides in the sliding groove to achieve guiding. Of course, the positions of the convex block and the sliding groove can be swapped.

[0074] Based on the fact that the limit block itself can precisely guide the movement of the elastic buckle through the limit groove in the present utility model, a guiding mechanism is formed by the sliding fit of the outer side wall of the limit block 50 and the inner side wall of the limit groove 401 along the moving direction of the elastic buckle 40. Or, a guiding mechanism is formed by the convex block and the sliding groove, achieving a double guiding effect, which can provide precise guidance for the movement of the elastic buckle 40, reduce the deviation during the movement process, and ensure that the elastic buckle 40 moves in a predetermined direction to effectively cooperate with the fastening part 21. At the same time, the precise guiding can reduce the wear degree between the limit block 50 and the limit groove 401, reduce the unnecessary friction and collision between the elastic buckle 40 and the accommodating groove 31, extend the service life of the elastic buckle 40, and improve the user's operation feel.

[0076] Each embodiment in this specification is described in a progressive manner. The same or similar parts between the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0077] The above description is only for the embodiments of the present utility model and is not used to limit the present utility model. For those skilled in the art, various modifications and changes can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
