Description

Technical Field

[0001] This application relates to the field of meat grinder technology, and in particular to a housing, a head assembly, and a household appliance. Background Technology

[0002] Household electric meat grinders are popular in the market due to their ease of use. Currently, the motor inside the grinder head of most household meat grinders is usually fixed to the outer casing with screws. However, because the motor itself is quite heavy, if the grinder head is accidentally dropped during handling or use, the motor can easily detach from the casing, causing damage to the motor or injury to the user. Utility Model Content

[0003] Therefore, it is necessary to provide a housing, a motor head assembly, and a household appliance to address the problem that the motor can easily detach from the lower housing.

[0004] A housing component, comprising:

[0005] end;

[0006] A cover portion is circumferentially disposed around the end portion, and the cover portion and the end portion together form a mounting cavity for accommodating a drive component;

[0007] The recessed portion is provided at one end in the first direction at the end of the mounting cavity, and the recessed portion is located inside the mounting cavity. The other end of the recessed portion in the first direction can abut against the drive member located inside the mounting cavity.

[0008] Beneficial effects: When the aforementioned housing is applied to the head assembly, in the event of the head assembly falling, the drive component, when it tends to move, can not only be tightened by the base, but also supported by the recessed portion on the housing. This prevents the drive component from shifting and falling off under the pull and push action, thus ensuring the safety of the drive component, extending product lifespan, and improving user experience.

[0009] In one embodiment, the recessed portion has a limiting hole at one end away from the end, and the limiting portion of the drive member located in the mounting cavity can pass through the limiting hole.

[0010] Beneficial effects: By abutting against the drive component, the movement of the drive component in the axial direction of the limiting hole is limited, and the movement of the drive component in the radial direction of the limiting hole is also limited. This further reduces the displacement of the drive component when the head assembly accidentally falls, reduces the safety hazards of the head assembly, and improves the service life of the product and the user experience.

[0011] In one embodiment, the end facing the first direction is recessed to form the recessed platform.

[0012] The beneficial effects are that the end and the recessed platform can be integrated into one unit, which helps to improve the support strength of the recessed platform for the drive component. At the same time, no additional fasteners are needed to connect the recessed platform and the end, which helps to reduce the number of parts in the housing and lower the production cost of the housing.

[0013] In one embodiment, the end portion, the cover portion, and the recessed platform portion are integrally formed.

[0014] The beneficial effects not only reduce the production cost of the housing components, but also improve the stability of the housing components when subjected to external impacts, which is more conducive to ensuring the support strength of the drive components.

[0015] In one embodiment, the recessed portion has a recessed surface at one end that abuts against the drive member, and the recessed surface is used to fit against the fixing surface of the drive member.

[0016] The beneficial effect is that the sinking platform can make surface-to-surface contact with the drive component, thereby increasing the contact area between the sinking platform and the drive component. When the head assembly falls, the sinking platform has sufficient contact area to hold the drive component in place, further reducing the probability of the drive component falling off.

[0017] A head assembly includes a base, a drive member, and a housing member as described in any of the preceding claims, wherein the housing member and the drive member are both disposed on the base, and the drive member is located within the mounting cavity.

[0018] Beneficial effects include that when the head assembly falls off, the drive component can be tightened by the base and supported by the recessed platform on the outer shell when it tends to move. This prevents the drive component from shifting and falling off under the pull and push action, thus ensuring the safety of the drive component, extending the product lifespan, and improving the user experience.

[0019] In one embodiment, the head assembly includes a plurality of head screws, the drive member has a plurality of fixing holes, the base has a plurality of mounting holes, each mounting hole corresponds to one fixing hole, all the head screws are arranged around the circumference of the drive member, and each head screw passes through one of the mounting holes and is threadedly connected to the corresponding fixing hole.

[0020] The beneficial effect is that the drive component is fixed to the base by multiple screws arranged around it, and the multiple screws ensure the fixed effect of the drive component on the base, further preventing the drive component from falling off the base.

[0021] In one embodiment, the base includes a baffle disposed around its circumferential edge, and one end of the cover portion away from the end is disposed between the baffle and the drive member.

[0022] The beneficial effect is that the end of the cover, furthest from the end cap, can be quickly installed into place with the help of the retaining edge. It should be noted that the cover can be installed on the base using screws or clips, etc., and there is no limitation here.

[0023] A household appliance comprising a head assembly as described in any of the preceding claims.

[0024] In one embodiment, the household appliance is a meat grinder, and the driving component is a motor.

[0025] When the aforementioned housing is applied to the head assembly, in the event of the head assembly falling, the drive component, when it tends to move, can not only be tightened by the base, but also supported by the recessed portion on the housing. This prevents the drive component from shifting and falling off under the pull and push action, thus ensuring the safety of the drive component, extending product lifespan, and improving user experience.

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] Before introducing the head assembly of this application, let's first describe the structure of the head assembly in a conventional meat grinder. In a conventional meat grinder, the head assembly includes a motor and blades. The motor drives the blades to rotate, thereby grinding the meat pieces placed in the container. Whether before or after grinding, the user needs to handle the head assembly to place it into or remove it from the container.

[0045] During handling, the machine head assembly can easily fall off. When it falls, the motor experiences a reverse impact force upon impact with the ground, causing it to tend to shift relative to the base 300. Currently, in traditional meat grinders, the motor in the machine head assembly is typically fixed directly to the base 300 with two screws. When the motor tends to shift relative to the base 300, relying solely on two screws to hold it in place makes it easy for the motor to detach from the base 300, potentially causing motor damage or injury.

[0046] Based on this, see Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of the housing 100 in one embodiment of this application is shown. Figure 2 It shows Figure 1A cross-sectional schematic diagram of the outer casing 100. The outer casing 100 provided in one embodiment of this application includes an end 10, a cover portion 20 and a recessed portion 30. The cover portion 20 is circumferentially arranged around the end 10, and the cover portion 20 and the end 10 form a mounting cavity 21. One end of the recessed portion 30 is disposed at the end 10 in the first direction X, and the recessed portion 30 is located in the mounting cavity 21.

[0047] In practical use, please refer to Figure 3 and Figure 4 The mounting cavity 21 is used to accommodate the drive component 200 of the motor and other head assembly, while the outer shell 100 is used to cooperate with the base 300 to cover the sides and top of the drive component 200, thereby protecting the drive component 200. Specifically, the cover portion 20 has an end portion 10 at one end in the first direction X, and an opening at the other end in the first direction X. The opening communicates with the mounting cavity 21. The base 300 is used to connect to the end of the cover portion away from the end portion 10 in the first direction X and to cover the opening.

[0048] The drive member 200 is mounted on the base 300 and located within the receiving cavity, and the other end of the recessed portion 30 in the first direction X can abut against the drive member 200 located within the recessed cavity. Thus, the drive member 200 located within the receiving cavity can be fixed not only by directly connecting to the base 300, but also by the recessed portion 30 provided on the housing 100.

[0049] In the event of a fall of the head assembly, when the drive component 200 tends to move, in addition to being tightened by the base 300, it can also be supported by the recessed portion 30 on the outer shell 100. This prevents the drive component 200 from shifting and falling off under the pull and support action, thereby ensuring the safety of the drive component 200, extending the product lifespan, and improving the user experience.

[0050] In some embodiments of this application, see [reference] Figure 4 and Figure 5 The recessed portion 30 has a limiting hole 31 at the end away from the end 10, and the driving member 200 has a limiting portion 210, which is located at the end of the driving member 200 away from the base 300. In actual use, the bottom of the driving member 200 is mounted on the base 300, and the top of the driving member 200 has the limiting portion 210. When the driving member 200 is located in the mounting cavity 21, the limiting portion 210 of the driving member 200 can pass through the limiting hole 31.

[0051] The axial direction of the limiting hole 31 is parallel to the first direction X, so that the movement of the limiting part 210 in the radial direction of the limiting hole 31 can be limited. When the head assembly accidentally falls, the drive member 200 will not only have a tendency to move relative to the base 300 in the first direction X, but also a tendency to move in the radial direction of the limiting hole 31. Through the cooperation of the limiting hole 31 and the limiting part 210, the movement of the drive member 200 in the radial direction of the limiting hole 31 can also be limited by the platform part 30, further reducing the displacement of the drive member 200.

[0052] In this way, by abutting against the drive component 200, the movement of the drive component 200 in the axial direction of the limiting hole 31 is limited. The movement of the drive component 200 in the radial direction of the limiting hole 31 is also limited by the limiting hole 31. This further reduces the displacement of the drive component 200 when the head assembly accidentally falls, reduces the safety hazards of the head assembly, and improves the service life of the product and the user experience.

[0053] In some embodiments of this application, the end of the end 10 facing the first direction X is recessed to form a recessed platform 30, that is, the side of the end 10 away from the mounting cavity 21 is recessed to form a recessed platform 30. In other words, the platform 30 is integrally formed with the end 10. This not only makes the end 10 and the platform 30 form a whole, which is beneficial to improve the support strength of the platform 30 for the drive member 200, but also eliminates the need for additional fasteners to connect the platform 30 and the end 10, which helps to reduce the number of parts in the housing 100 and reduce the production cost of the housing 100.

[0054] Furthermore, the end portion 10 and the cover portion 20 are also integrally formed. Combined with the aforementioned method of forming a recessed platform portion 30 in the end portion 10, the end portion 10, the cover portion 20, and the recessed platform portion 30 can be integrally formed and mounted as a single unit on the base 300. This not only reduces the production cost of the outer casing 100 but also improves its stability under external impact, thus better ensuring the support strength for the drive component 200.

[0055] It is readily understood that in some other embodiments, the end portion 10 may not have a recess, meaning the end face of the end portion 10 facing the first direction X is flat. In this case, although the recessed portion 30 is integrally formed with the end portion 10, the interior of the recessed portion 30 is a solid structure. In other embodiments, the recessed portion 30 may also be a separate component, meaning the recessed portion 30 can be detachably connected to the end portion 10 using screws or clips.

[0056] In some embodiments of this application, the recessed portion 30 has a recessed surface 32 at the end that abuts against the drive member 200. The recessed surface 32 is perpendicular to the first direction X and is arranged circumferentially around the limiting hole 31. Further, a fixing surface 220 is provided at the end of the drive member 200 away from the base 300, and the fixing surface 220 is arranged around the limiting portion 210 of the drive member 200. The fixing surface 220 can fit against the recessed surface 32, allowing the recessed portion 30 to have surface-to-surface contact with the drive member 200, thereby increasing the contact area between the recessed portion 30 and the drive member 200. When the head assembly falls, the recessed portion 30 has sufficient contact area to hold the drive member 200 in place, further reducing the probability of the drive member 200 falling off.

[0057] This application embodiment also provides a head assembly, including a base 300 and a drive component 200 as in any of the above embodiments, and a housing 100. Both the housing 100 and the drive component 200 are disposed on the base 300, and the drive component 200 is located within the mounting cavity 21. Thus, in the event of the head assembly falling, when the drive component 200 tends to move, in addition to being tightened by the base 300, the drive component 200 can also be supported by the recessed portion 30 provided on the housing 100. This prevents the drive component 200 from easily displacing and falling off under the pulling and supporting action, thereby ensuring the safety of the drive component 200, extending product lifespan, and improving user experience.

[0058] In some embodiments of this application, the head assembly includes multiple head screws 310, the drive member 200 has multiple fixing holes 230, and the base 300 has multiple mounting holes 320, each mounting hole 320 corresponding to one fixing hole 230. All the head screws 310 are arranged around the circumference of the drive member 200, and each head screw 310 passes through one of the mounting holes 320 and is threadedly connected to the corresponding fixing hole 230. In this way, the drive member 200 can be fixed to the base 300 by the multiple head screws 310 arranged around the drive member 200, and the multiple head screws 310 ensure the fixed effect of the drive member 200 on the base 300, further preventing the drive member 200 from falling off the base 300.

[0059] In some embodiments of this application, the base 300 includes a retaining edge 330 surrounding its circumferential edge. The end of the cover portion 20 away from the end 10 is located between the retaining edge 330 and the driving member 200, so as to limit the installation of the cover portion 20 by means of the retaining edge 330. In actual use, after the driving member 200 is installed on the base 300 by the head screw 310, the outer shell 100 is placed over the driving member 200, and the end of the cover portion 20 away from the end 10 can be quickly installed into place under the action of the retaining edge 330. It should be noted that the cover portion can be installed on the base 300 by screws or by clips, etc., and is not limited here.

[0060] This application also provides a household appliance, including the head unit assembly as described in any of the above embodiments, specifically... Figure 1 In this embodiment, the household appliance is a meat grinder, and the drive component 200 is a motor. In other embodiments, the household appliance may also be an appliance with a detachable motor head, such as a fan, and there is no limitation on this. Since the household appliance includes all the technical features of the aforementioned motor head assembly, it possesses all the technical effects of the aforementioned motor head assembly, which will not be elaborated further here.

[0061] The aforementioned housing 100 has at least the following advantages:

[0062] In the event of a fall of the head assembly, when the drive component 200 tends to move, in addition to being tightened by the base 300, it can also be supported by the recessed portion 30 on the outer shell 100. This prevents the drive component 200 from shifting and falling off under the pull and support action, thereby ensuring the safety of the drive component 200, extending the product lifespan, and improving the user experience.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
