Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a support structure and a household appliance. Background Technology

[0002] Current fans typically consist of a fan head, a support rod, and a chassis. The fan head comprises a motor, fan blades, and a protective grille. During use, the fan head is supported by the support rod mounted on the base. Currently, the fan head is usually connected to the support rod with screws, requiring rotation to disassemble it. The fan head is usually quite large, and its center is not on the axis of the support rod, making rotation difficult and resulting in time-consuming and laborious disassembly for the user. Utility Model Content

[0003] Therefore, it is necessary to provide a support structure and household appliances to address the problem of time-consuming and laborious disassembly of the machine head by users.

[0004] A support structure, the support structure comprising:

[0005] A support rod having a first end and a second end opposite each other along a first direction;

[0006] The lifting rod is movably disposed on the support rod along a first direction and has a first position during the movement;

[0007] The connector has a snap-fit ​​state and a detached state. When the connector is in the snap-fit ​​state, the connector is snapped into the lifting rod and is used to prevent the connector from moving relative to the lifting rod in the first direction. When the connector is in the detached state, the connector can be detached from the lifting rod in a direction away from the second end.

[0008] Wherein, the first end is close to the connector, when the connector is in the fastened state and the lifting rod is in the first position, during the process of the connector moving toward the second end, the connector can abut against the first end of the support rod; or the support rod drives the connector to switch from the fastened state to the disengaged state.

[0009] In one embodiment, when the connector is in the disengaged state, the connector is movable relative to the lifting rod in the first direction, and when the connector moves relative to the lifting rod toward the second end, the connector can abut against the lifting rod, and the lifting rod is used to drive the connector to switch from the disengaged state to the engaged state.

[0010] In one embodiment, one of the lifting rod and the connector has a mating portion, and the other has a snap-fit ​​space;

[0011] When the connector is in the engaged state, the mating part is located in the snap-fit ​​space; when the connector is in the disengaged state, at least one end of the mating part in the first direction is located outside the snap-fit ​​space.

[0012] In one embodiment, the lifting rod and the connector having the snap-fit ​​space include a limiting portion and a snap-fit ​​portion spaced apart along the first direction, and a snap-fit ​​space is formed between the limiting portion and the snap-fit ​​portion.

[0013] In one embodiment, the snap-fit ​​portion is provided with an insertion ramp on the side facing the second end, the insertion ramp intersecting the first direction but not perpendicular to it;

[0014] Alternatively, an insertion ramp may be provided on the side of the mating part away from the second end, the insertion ramp intersecting the first direction but not perpendicular to it.

[0015] In one embodiment, both the mating part and the snap-fit ​​space include multiple parts, and all the mating parts and all the snap-fit ​​spaces are arranged circumferentially around the lifting rod. Each mating part can enter or exit one of the snap-fit ​​spaces.

[0016] In one embodiment, the connector includes a connector body and a snap fastener, the snap fastener being disposed on the connector body, and the mating portion or the snap fastening space being disposed on the snap fastener;

[0017] When the connector moves toward the second end, the buckle can abut against the support rod;

[0018] Alternatively, the support rod is used to drive the buckle to bend relative to the insertion body, and during the bending process, the mating part and the snap-fit ​​space move away from each other.

[0019] In one embodiment, the buckle includes a fastening part, a connecting part, and a sliding part. The fastening part extends longitudinally along the first direction and one end is connected to the insertion body. The snapping space or the mating part is provided in the fastening part.

[0020] The connecting portion extends along a second direction perpendicular to the first direction, and one end of the connecting portion is connected to the other end of the fastening portion. The other end of the connecting portion is connected to one end of the actuating portion. The other end of the actuating portion extends longitudinally in a direction away from the fastening portion, and the extending direction of the actuating portion intersects both the first direction and the second direction.

[0021] In one embodiment, the support rod is provided with an anti-disengagement hole at the first end. When the connector moves toward the second end, the buckle can extend into the anti-disengagement hole and abut against the edge of the anti-disengagement hole.

[0022] In one embodiment, as the lifting rod moves away from the second end from the first position, the lifting rod has a second position. When the lifting rod is in the second position, the support rod can cooperate with the lifting rod and prevent the lifting rod from continuing to move relative to the support rod in the first direction.

[0023] In one embodiment, the support rod includes a support rod body and an anti-detachment component, the anti-detachment component being located at the end of the support rod body facing the connector; the lifting rod includes a lifting rod body and a cover plate, the cover plate being disposed at one end of the lifting rod body, and the connector being disposed at the other end of the lifting rod body.

[0024] The cover plate has a lifting hole, and the support rod passes through the lifting hole. When the lifting rod moves to the second position, the cover plate and the anti-detachment component cooperate with each other to prevent the lifting rod from continuing to move relative to the support rod in the first direction.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] See Figure 1 , Figure 1 A schematic diagram of a household appliance according to an embodiment of this application is shown. The appliance is a fan, which includes a fan head 100 and a support structure. The fan head 100 consists of a motor, fan blades, and a protective mesh, and is mainly used to generate airflow to blow towards the user. The support structure is connected to the fan head 100, thereby supporting the fan head 100 on a mounting base such as the ground or a tabletop, so that the fan head 100 has sufficient height, thereby increasing the coverage area of ​​the airflow generated by the fan head 100 and improving the user experience.

[0050] The support structure includes a support rod 10, a lifting rod 20, and a connector 30. The support rod 10 extends longitudinally along a first direction X and has a first end 11 and a second end 12 opposite to each other in the first direction X. The second end 12 is used for placement or fixing on a mounting base such as the ground or a tabletop. The lifting rod 20 is movably mounted on the support rod 10 along the first direction X and has a first position during movement. The connector 30 is detachably mounted on the lifting rod 20 and is used to connect to the machine head 100. It should be noted that the connector 30 can be connected to the machine head 100 by bolts, clips 41, or by direct integral molding, and is not limited here.

[0051] Among them, see Figure 2 The connector 30 has a engaged state and a disengaged state. When the connector 30 is in the engaged state, it is engaged with the lifting rod 20 and prevents the connector 30 from moving relative to the lifting rod 20 in the first direction X. Thus, when the connector 30 is in the engaged state, it can be fixed to the lifting rod 20, thereby fixing the machine head 100 to the lifting rod 20, i.e., fixing the machine head 100 to the support structure. Even if the user lifts the machine head 100, it will not be pulled out of the lifting rod 20, avoiding the problem of the machine head 100 falling off.

[0052] Furthermore, the first end 11 is close to the plug-in component 30. When the plug-in component 30 is in the engaged state and the lifting rod 20 is in the first position, as the plug-in component 30 moves toward the second end 12, it can abut against the first end 11 of the support rod 10. As the plug-in component 30 continues to move toward the second end 12, the support rod 10 can drive the plug-in component 30 to switch from the engaged state to the disengaged state. The end of the lifting rod 20 away from the second end 12 has a connector 26 for mounting the machine head 100. When the plug-in component 30 is in the disengaged state, it can be detached from the lifting rod 20 via the connector 26 in a direction away from the second end 12.

[0053] In actual use, the first direction X is vertical. When the user needs to disassemble, transport or store the fan, the head 100 can be pressed down. During the pressing down of the head 100, the connector 30 and the lifting rod 20 will move together toward the second end 12, so that the connector 30 abuts against the support rod 10. Under the action of the support rod 10, the connector 30 switches to the detached state, so that the connector 30 can be detached from the lifting rod 20 through the connector 26.

[0054] When the connector 30 is in the detached state, it can be detached from the lifting rod 20 in a direction away from the second end 12. That is, the machine head 100, along with the connector 30, can be detached from the lifting rod 20, thus completing the disassembly of the machine head 100. During the disassembly of the machine head 100, the user only needs to press the machine head 100 downwards first, and then pull the machine head 100 upwards from the connector 26. There is no need to rotate the machine head 100, thus saving the user the steps required to disassemble the machine head 100 and improving the speed of disassembly.

[0055] It should be noted that the aforementioned household appliance may be, but is not limited to, a fan. In some other embodiments, the household appliance may also be a floor lamp with the lamp head connected to the connector 30. In still other embodiments, the household appliance may also be other electrical appliances that require support, which are not limited here.

[0056] In some embodiments of this application, when the connector 30 is in the detached state, the connector 30 is movable relative to the lifting rod 20 along the first direction X, and when the connector 30 moves relative to the lifting rod 20 toward the second end 12, the connector 30 can abut against the lifting rod 20. The lifting rod 20 is used to drive the connector 30 to switch from the detached state to the engaged state, so that the connector 30 can engage with the lifting rod 20 to fix the machine head 100 on the lifting rod 20.

[0057] In actual use, when the user needs to install the machine head 100, they align the connector 30 on the machine head 100 with the connector 26 on the lifting rod 20 and press the machine head 100 down firmly to engage the connector 30, thus securing the machine head 100 to the support structure. Conversely, when the user needs to disassemble the machine head 100, they can press it down further to pull it out of the connector 26. Thus, whether installing or disassembling the machine head 100, the user only needs to press the machine head 100, effectively improving the convenience of installation and disassembly.

[0058] In some embodiments of this application, see [reference] Figure 3 and Figure 4 In order to achieve the mutual engagement of the connector 30 and the lifting rod 20, the lifting rod 20 has a mating part 21 and the connector 30 has a snap-fit ​​space 33. When the connector 30 is in the engaged state, the mating part 21 is located in the snap-fit ​​space 33. The connector 30 can limit the upper and lower ends of the mating part 21, thereby preventing the connector 30 from moving relative to the lifting rod 20 in the first direction X.

[0059] When the connector 30 is in the detached state, the end of the mating part 21 facing the support rod 10 in the first direction X is located outside the snap-fit ​​space 33. At this time, when the connector 30 moves upward, the limiting space 33 cannot cooperate with the mating part 21 to limit the connector 30, thereby allowing the connector 30 to move upward to be pulled out from the connector 26 of the support rod 10.

[0060] In some specific embodiments, the connector 30 has a limiting part 31 and a snap-fit ​​part 32 spaced apart along the first direction X, and a snap-fit ​​space 33 is formed between the limiting part 31 and the snap-fit ​​part 32. At this time, the limiting part 31 and the snap-fit ​​part 32 limit the upper and lower ends of the mating part 21, thereby preventing the connector 30 from moving relative to the lifting rod 20 along the first direction X.

[0061] When the connector 30 is in the detached state, the end of the mating part 21 facing the support rod 10 in the first direction X is outside the snap-fit ​​space 33, so the snap-fit ​​part 32 will no longer abut against the bottom of the mating part 21. Since the limiting part 31 is above the mating part 21, it will also not abut against the mating part 21, thereby allowing the connector 30 to move upward to be pulled out from the connector 26 of the support rod 10.

[0062] In other embodiments, the lifting rod 20 may be provided with a limiting part 31 and a locking part 32, that is, the lifting rod 20 is provided with a locking space 33, and the connector 30 is provided with a mating part 21. When the connector 30 is in the engaged state, the mating part 21 is still located in the locking space 33, and the limiting part 31 and the locking part 32 limit the mating part 21. When the connector 30 is in the disengaged state, both ends of the mating part 21 are located outside the locking space 33 in the first direction X. At this time, the limiting part 31 and the locking part 32 can no longer limit the mating part 21, so that the connector 30 can move upward to be pulled out from the insertion interface 26 of the support rod 10.

[0063] In some embodiments, the connector 30 includes a connector body 40 and a latch 41. The connector body 40 is used to connect to the machine head 100. The latch 41 has its first end disposed on the connector body 40 in the first direction X. A latching space 33 and a latching portion 32 are disposed on the latch 41. As can be seen from the above, since the limiting portion 31 is disposed above the mating portion 21, it will not interfere with the mating portion 21 when the connector 30 is withdrawn. Therefore, the limiting portion 31 can be disposed on the latch 41 or on the connector body 40, as long as it is spaced apart from the latching portion 32 along the first direction X to form a latching space 33, and the latching space 33 is located on the latch 41. No limitation is made here.

[0064] When the plug-in 30 in the engaged state moves toward the second end 12 relative to the lifting rod 20, the latch 41 can abut against the support rod 10. As the plug-in 30 continues to move, the support rod 10 can drive the latch 41 to bend relative to the plug-in body 40 toward the direction away from the mating part 21, and drive the snap-fit ​​part 32 located on the latch 41 to move toward the direction away from the mating part 21, so that the mating part 21 and the snap-fit ​​space 33 move away from each other, until the end of the mating part 21 facing the support rod 10 in the first direction X is outside the snap-fit ​​space 33. At this time, the plug-in 30 switches to the disengaged state, and the plug-in 30 can be removed from the lifting rod 20.

[0065] In the embodiment where the mating part 21 is provided on the buckle 41, and the limiting part 31 and the snap-fit ​​part 32 are provided on the lifting rod 20, the support rod 10 can be used to drive the buckle 41 to bend relative to the insertion body 40 in a direction away from the limiting part 31 and the snap-fit ​​part 32, thereby causing the mating part 21 located on the buckle 41 to bend in a direction away from the limiting part 31 and the snap-fit ​​part 32. The bending of the buckle 41 can also make the mating part 21 and the snap-fit ​​space 33 move away from each other, thereby making the mating part 21 leave the snap-fit ​​space 33 between the limiting part 31 and the snap-fit ​​part 32, and then the insertion member 30 can extend out from the lifting rod 20.

[0066] In some embodiments, the buckle 41 includes a fastening portion 42, a connecting portion 43, and a levering portion 44. The fastening portion 42 extends longitudinally along a first direction X, and one end is connected to the insertion body 40. A locking portion 32 or a mating portion 21 is disposed on the fastening portion 42, and when the locking portion 32 is disposed on the fastening portion 42, a locking space 33 is disposed on the fastening portion 42. The connecting portion 43 extends longitudinally along a second direction Y perpendicular to the first direction X, and one end of the connecting portion 43 is connected to the other end of the fastening portion 42. The other end of the connecting portion 43 is connected to one end of the levering portion 44. The other end of the levering portion 44 extends longitudinally in a direction away from the fastening portion 42, and the extension direction of the levering portion 44 intersects both the first direction X and the second direction Y. Wherein, the first direction X is the extension direction of the support rod 10, and the second direction Y is the radial direction of the support rod 10.

[0067] Thus, when the plug-in 30 in the engaged state moves relative to the lifting rod 20 toward the second end 12, the end of the actuating part 44 away from the connecting part 43 can abut against the support rod 10, and the support rod 10 applies an upward bending force to the connecting part 43. Since the actuating part 44 is inclined, it will bend obliquely upward relative to the connecting part 43, and drive the connecting part 43 to bend obliquely upward, and finally drive the engaging part 42 and the connecting part 43 or the mating part 21 on the engaging part 42 to bend obliquely upward together, so that the locking part 32 disengages from the mating part 21, or the mating part 21 disengages from the locking space 33.

[0068] It should be noted that when both the limiting part 31 and the locking part 32 are provided on the buckle 41, when the machine head 100 drives the connector 30 to move downward, the limiting part 31 will drive the mating part 21 to move together, so that the lifting rod 20 will move downward together. However, after the buckle 41 abuts against the support rod 10, the buckle 41 will drive the locking part 32 to bend upward. Therefore, the locking part 32 will move relative to the mating part 21 in the vertical direction, so that after the buckle 41 bends, the locking part 32 will leave the bottom of the mating part 21 and be located on the side of the mating part 21. At this time, the connector 30 is in a disassembled state. Afterward, as the connector 30 is disassembled upward, since the locking part 32 is already located on the side of the mating part 21, even if the buckle 41 returns to its original shape, the locking part 32 will still abut against the mating part 21 and move along the side surface of the mating part 21 to leave the support rod 10 together with the connector 30.

[0069] When the mating part 21 is mounted on the buckle 41, and the limiting part 31 and the locking part 32 are mounted on the support rod 10, when the machine head 100 drives the connector 30 to move downward, it can abut against the lifting rod 20 through the housing of the machine head 100. This allows the machine head 100 to directly drive the lifting rod 20 downward, so that after the buckle 41 bends upward, the mating part 21 can move upward. The mating part 21, the limiting part 31, and the locking part 32 are positioned away from each other in the first direction X. Afterward, the connector 30 is disengaged upward, the buckle 41 returns to its original shape, and the side of the mating part 21 abuts against the limiting part 31. Then, the mating part 21 leaves the support rod 10 along with the buckle 41 and the connector 30.

[0070] As can be seen from the above, regardless of whether the mating part 21 is located on the buckle 41 or the support rod 10, the side of the mating part 21 must abut against the snap-fit ​​part 32 or the limiting part 31 during the process of removing the connector 30 from the support rod 10. In order to prevent the snap-fit ​​part 32 or the limiting part 31 from getting stuck in the mating part 21 and causing the connector 30 to be unable to be disassembled, the surface of the mating part 21 facing the buckle 41 is a plane, which is parallel to the first direction X, that is, a plane along the vertical direction.

[0071] In some specific embodiments, the support rod 10 is provided with an anti-disengagement hole 13 at its first end 11. When the connector 30 moves relative to the lifting rod 20 toward the second end 12, the buckle 41 can extend into the anti-disengagement hole 13. The edge of the anti-disengagement hole 13 abuts against the buckle 41, and as the connector 30 moves, the edge of the anti-disengagement hole 13 can drive the buckle 41 to deform relative to the connector body 40, so that the buckle 41 bends. Thus, when the actuating part 44 of the buckle 41 is inserted into the anti-disengagement hole 13, the edge of the anti-disengagement hole 13 can apply an upward force to the actuating part 44 and a horizontal force to the actuating part 44, so that the force applied by the support member to the actuating part 44 is obliquely upward, which is conducive to driving the buckle 41 to flip.

[0072] In some other embodiments, the support rod 10 can also be a plane at the first end 11. When one end of the actuating part 44 slides on the plane of the support rod 10, it can cause the buckle 41 to flip.

[0073] In some specific embodiments, the lifting rod 20 is sleeved around the support rod 10 in the circumferential direction, so that the lifting rod 20 can move relative to the support rod 10 in the first direction X. The mating parts 21 and the locking spaces 33 are multiple, and all mating parts 21 and locking spaces 33 are spaced apart circumferentially around the lifting rod 20. Each mating part 21 can enter or exit one of the locking spaces 33, so that the support of the machine head 100 is more stable through the multiple mating parts 21 and multiple locking spaces 33.

[0074] In one specific embodiment, the mating part 21 is provided on the lifting rod 20, and both the mating part 21 and the buckle 41 include multiple parts. All mating parts 21 and all buckles 41 are arranged circumferentially around the lifting rod 20. Each buckle 41 is provided with a limiting part 31 and a snap-fit ​​part 32, so that each buckle 41 forms a snap-fit ​​space 33. Each mating part 21 can be engaged with one of the buckles 41. That is, through multiple buckles 41 and multiple mating parts 21, the machine head 100 can be more stable when it is installed on the lifting rod 20 through the connector 30, and the support structure provides better support for the machine head 100.

[0075] When the limiting part 31 and the locking part 32 are provided on the lifting rod 20, the limiting part 31 and the locking part 32, which are spaced apart along the first direction X, form a set of limiting structures. The lifting rod 20 is provided with multiple sets of limiting structures. Each limiting structure forms a locking space 33 through the limiting part 31 and the locking part 32. The buckle 41 includes multiple buckles. All mating parts 21 and all buckles 41 are spaced apart around the circumference of the lifting rod 20. The mating part 21 on each buckle 41 can engage with one of the limiting structures, so that the machine head 100 can be stably supported by multiple limiting structures and multiple buckles 41.

[0076] In some embodiments, when the latch 41 is provided with a limiting part 31 and a locking part 32, during the installation of the machine head 100, the connector 30 needs to be inserted downward into the lifting rod 20. However, during the insertion of the connector 30 into the lifting rod 20, the locking part 32 will abut against the mating block, thus affecting the insertion of the connector. Therefore, the locking part 32 is provided with an insertion ramp 34 on the side facing the second end 12. The insertion ramp 34 intersects the first direction X but is not perpendicular to it, and in the direction from the second end 12 to the first end 11, the distance between the insertion ramp 34 and the inner wall of the lifting rod 20 gradually increases in the radial direction of the lifting rod 20. Thus, during the process of the insert entering the lifting rod 20, the insertion ramp 34 will abut against the top of the mating part 21, and under the guidance of the insertion ramp 34, the buckle 41 will bend relative to the insert body 40, so that the snap-fit ​​part 32 can pass over the mating part 21 until the snap-fit ​​part 32 enters the lower part of the mating part 21, and engages with the limiting part 31 above the mating part 21 to achieve the snap-fit ​​between the buckle 41 and the mating part 21.

[0077] In the embodiment where the buckle 41 is provided with a mating part 21, an insertion ramp 34 is provided on the side of the mating part 21 away from the second end 12. The insertion ramp 34 intersects the first direction X but is not perpendicular to it. In the direction from the second end 12 to the first end 11, the distance between the insertion ramp 34 and the inner wall of the lifting rod 20 in the radial direction of the lifting rod 20 gradually increases. Thus, during the process of the insert entering the lifting rod 20, the insertion ramp 34 will abut against the top of the limiting part 31. Under the guidance of the insertion ramp 34, the buckle 41 will bend relative to the insertion body 40, so that the mating part 21 can pass over the limiting part 31 until the locking part 32 enters between the limiting part 31 and the locking part 32, thereby realizing the fastening of the buckle 41 with the limiting part 31 and the locking part 32.

[0078] In some embodiments of this application, see [reference] Figure 6 and Figure 7 During the movement of the lifting rod 20 away from the second end 12 in the first position, the lifting rod 20 has a second position. When the lifting rod 20 is in the second position, the support rod 10 can cooperate with the lifting rod 20 and prevent the lifting rod 20 from moving relative to the support rod 10 in the first direction X. In actual use, as the lifting rod 20 moves away from the second end 12, it can cause the machine head 100 to move upward, thereby increasing the height of the machine head 100.

[0079] Optionally, the second position is the highest position of the lifting rod 20 relative to the support rod 10 during the upward process. When the lifting rod 20 moves to the highest position, the support rod 10 and the lifting rod 20 can be engaged and fixed in the second position by means of a snap-fit ​​41, interference fit, bolts, etc. It is understood that when the lifting rod 20 is in the first position, since the lifting rod 20 still needs to move downward to disassemble the machine head 100, the lifting rod 20 in the first position is not at the extreme position of the downward movement of the lifting rod 20.

[0080] Specifically, the support rod 10 includes a support rod body 14 and an anti-detachment component 15. The anti-detachment component 15 is located at the end of the support rod body 14 facing the connector 30. The anti-detachment component 15 is provided with the aforementioned anti-detachment hole 13. The anti-detachment component 15 can be installed on the support member by bolt fixing, thread fixing, adhesive, snap-fit ​​fixing, interference fit, etc., and no limitation is made here. Figure 7 In the middle, the bottom of the anti-detachment component 15 is inserted into the top of the support rod 14 and is interference-fitted with the support rod 14 so that the anti-detachment component 15 can be fixed on the support rod 14.

[0081] The lifting rod 20 includes a lifting rod body 22 and a cover plate 23. The cover plate 23 is located at one end of the lifting rod body 22, and the other end of the lifting rod body 22 is provided with a connector 30. A lifting hole 24 is provided on the cover plate 23, through which the support rod 14 passes. When the lifting rod body 22 moves to the second position, the cover plate 23 and the connector 30 cooperate with each other, preventing the lifting rod body 22 from continuing to move relative to the support rod 14 in the first direction X. The cooperation between the cover plate 23 and the connector 30 can be achieved through bolt fixing, thread fixing, adhesive bonding, snap-fit ​​fixing, interference fit, etc., to fix the cover plate 23 and the connector 30 to each other. Specifically... Figure 8 In one embodiment, the cover plate 23 has a cover plate hole 25, which is coaxially arranged with the lifting hole 24. The diameter of the cover plate hole 25 is larger than that of the lifting hole 24. When the lifting rod 20 is in the second position, the anti-detachment member 15 is inserted into the cover plate hole 25, and the anti-detachment member 15 is interference-fitted with the cover plate 23 so that the lifting rod 20 is fixed in the second position.

[0082] In some embodiments of this application, the household appliance further includes a base 50, with the second end 12 of the support rod 10 disposed on the base 50. The base 50 has a large supporting surface, enabling it to be stably placed on a supporting foundation such as the ground. The support rod 10 is mounted on the base 50, ensuring that the support rod 10 is not prone to tipping over. Optionally, the base 50 is connected to the second end 12 of the support rod 10 by bolts.

[0083] The following combination Figure 2 The disassembly and assembly process of the head unit 100 in this application is described as follows:

[0084] The first step is the installation of the machine head 100. The connector 30 on the machine head 100 is aligned with the connector hole on the lifting rod 20, so that the machine head 100 and the connector 30 move downward under the action of gravity. The buckle 41 of the connector 30 is bent by the connector slope, and finally the buckle 41 is engaged with the mating part 21 inside the lifting rod 20 to complete the installation of the machine head 100.

[0085] When it is necessary to disassemble the machine head 100, by pressing the machine head 100, the buckle 41 extends into the anti-disengagement hole 13. Under the action of the edge of the anti-disengagement hole 13, the buckle 41 flips over. The buckle 41 drives the locking part 32 on itself to flip over as well, so that the locking part 32 leaves the bottom of the mating part 21 and enters the side of the mating part 21, and then contacts the buckle 41 and the mating part 21 to engage. At this time, the machine head 100 can be pulled upward to complete the disassembly of the machine head 100.

[0086] The aforementioned support structure has at least the following advantages:

[0087] During the disassembly of the head 100, the user only needs to press the head 100 downwards and then pull it upwards from the connector 26. There is no need to rotate the head 100, which saves the user the steps of disassembling the head 100 and improves the speed of disassembly.

[0088] 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.

[0089] 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.
