Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It is installed directly above the stove and draws in and exhausts cooking fumes through its vents. The fumes contain gaseous or tiny liquid grease particles, which are intercepted and condensed into oil droplets inside the range hood, eventually forming a liquid oil.

[0003] Typically, range hoods have a removable oil cup at the bottom. During operation, the oil inside the range hood flows downward into the oil cup, which collects the oil to prevent it from dripping onto the kitchen stove and polluting the kitchen environment.

[0004] Traditional range hoods have a first mounting bracket at the bottom and a second mounting bracket for the grease cup. The first and second brackets are engaged to hold the grease cup at the bottom of the range hood. However, if the user accidentally touches the grease cup, it can easily fall off, causing the grease inside to spill out. Furthermore, when installing the grease cup, the second mounting bracket needs to be fitted into the small gap between the range hood and the first mounting bracket, which is inconvenient for the user and affects the user experience. Utility Model Content

[0016] In one embodiment, the second snap-fit ​​member is rotatably disposed within the receiving cavity, such that the second snap-fit ​​member has a snap-fit ​​position and a clearance position that avoids the insertion part. During the process of the insertion part entering the receiving cavity from the insertion hole, the insertion part can compress the second snap-fit ​​member to rotate to the clearance position. In the clearance position, the slot of the card groove is opposite to the second snap-fit ​​member. The second snap-fit ​​member can also rotate from the clearance position to the snap-fit ​​position so that the second snap-fit ​​member enters the card groove.

[0017] In one embodiment, the insertion portion is provided with a bevel, which is used to press the second snap-fit ​​member to cause the second snap-fit ​​member to rotate and avoid the insertion portion.

[0018] In one embodiment, the second snap-fit ​​member is rotatably disposed within the receiving cavity, such that the second snap-fit ​​member has a snap-fit ​​position for engaging with the first snap-fit ​​member and a disengagement position for disengaging from the first snap-fit ​​member;

[0048] 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.

[0049] A range hood is a kitchen appliance installed directly above the stove to purify the kitchen environment. It draws in cooking fumes through its vents and then exhausts them. Typically, cooking fumes contain gaseous or tiny liquid grease particles, which are intercepted and condensed into oil droplets inside the range hood, eventually forming a liquid oil. However, this liquid oil flowing out of the range hood can pollute the kitchen environment.

[0050] Therefore, refer to Figure 1 One embodiment of this application provides a range hood, including a range hood body 10 and an oil cup 20. The oil cup 20 is detachably disposed at the bottom of the range hood body 10. During the operation of the range hood body 10, the oil inside the range hood body 10 flows downward into the oil cup 20, where it collects the oil to prevent it from dripping onto the kitchen stove and polluting the kitchen environment. When the oil cup 20 is full, the user can remove the oil cup 20 from the range hood body 10 for cleaning. After cleaning, the oil cup 20 can be reinstalled at the bottom of the range hood body 10.

[0051] Traditional range hoods have a first hanging ear at the bottom of the main body 10 and a second hanging ear on the oil cup 20. The first and second hanging ears are engaged to detachably mount the oil cup 20 to the bottom of the main body 10. However, if a user accidentally touches the oil cup 20, it can easily fall off, causing the oil inside to spill out and affecting the user experience.

[0052] Therefore, refer to Figure 1 , Figure 2 and Figure 4 The range hood also includes a first latching member 30 and a limiting component 40. The first latching member 30 is disposed on one of the range hood body 10 and the oil cup 20, and the limiting component 40 is disposed on the other of the range hood body 10 and the oil cup 20.

[0053] In this embodiment, see Figure 1 The first snap-fit ​​component 30 is located at the bottom of the range hood body 10, and the limiting component 40 is located at the oil cup 20.

[0054] See Figure 4 , Figure 6 , Figure 7 and Figure 8 The limiting component 40 includes a housing 41 and a second snap-fit ​​member 42. The housing 41 has a receiving cavity 4116 and a socket 4121, the receiving cavity 4116 and the socket 4121 are connected, and the second snap-fit ​​member 42 is disposed in the receiving cavity 4116. At least a portion of the first snap-fit ​​member 30 is disposed in the receiving cavity 4116 through the socket 4121 and is snap-fitted with the second snap-fit ​​member 42 to detachably mount the oil cup 20 to the bottom of the range hood body 10.

[0055] During installation, place the oil cup 20 under the main body 10 of the range hood, aligning the insertion hole 4121 with the first snap-fit ​​connector 30. Then, push the oil cup 20 upwards, causing at least a portion of the first snap-fit ​​connector 30 to enter the receiving cavity 4116 through the insertion hole 4121 and engage with the second snap-fit ​​connector 42 to form a mechanical interlock. This improves the stability of the oil cup 20 installation, preventing it from being accidentally dislodged by the user, thus enhancing the user experience. Furthermore, the fact that at least a portion of the first snap-fit ​​connector 30 extends into the receiving cavity 4116 through the insertion hole 4121 allows for connection with the second snap-fit ​​connector 42, further improving the ease of installation and enhancing the user experience.

[0056] In one embodiment, see Figure 4The oil cup 20 is equipped with an oil collection trough 21 and an installation groove 22. The oil collection trough 21 and the installation groove 22 are not connected to each other. The oil collection trough 21 is used to collect the oil flowing out of the range hood body 10, and the limiting component 40 is located in the installation groove 22. In this way, the limiting component 40 is physically isolated from the oil, ensuring that the oil in the oil collection trough 21 will not seep into the installation groove 22, and preventing the limiting component 40 from getting stuck due to oil accumulation, thereby ensuring that the limiting component 40 can be used normally.

[0057] Of course, in other embodiments, the first snap-fit ​​member 30 may also be disposed in the mounting slot 22.

[0058] Further, see Figure 4 and Figure 5 The oil cup 20 is provided with a partition 23, which divides the internal space of the oil cup 20 into an oil collection groove 21 and an installation groove 22.

[0059] In one embodiment, see Figure 4 There are two mounting slots 22, located on opposite sides of the oil collecting groove 21. It can be understood that the two mounting slots 22 are located at opposite ends of the oil cup 20. There are two limiting components 40, each corresponding to one of the two mounting slots 22.

[0060] Further, see Figure 1 Two first locking members 30 are provided, one on each side of the bottom of the range hood body 10. The two first locking members 30 are engaged with the second locking members 42 of the two limiting components 40 in a one-to-one manner. In this way, the installation of the oil cup 20 can be further improved, and the oil cup 20 can be effectively prevented from falling off.

[0061] In one embodiment, see Figure 6 The outer casing 41 includes a housing 411 and a cover 412. The housing 411 has a receiving cavity 4116 and an opening, and the receiving cavity 4116 communicates with the opening. The cover 412 is located at the opening and is connected to the housing 411. The second snap-fit ​​member 42 is located inside the housing 411, and the insertion hole 4121 is located in the cover 412.

[0062] Optionally, the housing 411 is a cuboid. For details, see [link to relevant documentation]. Figure 11The housing 411 includes a first side plate 4111, a second side plate 4112, a third side plate 4113, a fourth side plate 4114, and a bottom plate 4115. The first side plate 4111 and the second side plate 4112 are located on opposite sides of the bottom plate 4115 in a second direction, and the third side plate 4113 and the fourth side plate 4114 are located on opposite sides of the bottom plate 4115 in the first direction. The first direction intersects with the second direction. Optionally, the first direction is perpendicular to the second direction, denoted by X and the second direction by Y. The first side plate 4111, the second side plate 4112, the third side plate 4113, the fourth side plate 4114, and the bottom plate 4115 form a receiving cavity 4116, and the cover 412 is disposed opposite to the bottom plate 4115.

[0063] In one embodiment, the first side plate 4111 is connected to the oil cup 20 by a first fastener, and the third side plate 4113 is connected to the partition plate 23 by a second fastener. Optionally, the first and second fasteners are screws or the like.

[0064] Further, see Figure 4 , Figure 5 and Figure 11 The oil cup 20 has a first fixing hole, and the first side plate 4111 has a second fixing hole. A hollow first fixing post 4117 is located on the side of the first side plate 4111 facing the second side plate 4112. The second fixing hole communicates with the first fixing hole and the hollow first fixing post 4117. Optionally, both the first and second fixing holes are screw holes. During installation, one end of the first fixing member is placed inside the hollow first fixing post 4117 through the first and second fixing holes and connected to the first fixing post 4117. This allows for the connection between the first side plate 4111 and the oil cup 20, while ensuring that oil does not seep into the limiting component 40, preventing the limiting component 40 from becoming stuck due to oil accumulation, thus ensuring the normal operation of the limiting component 40.

[0065] Further, see Figure 4 , Figure 5 and Figure 11 The partition 23 has a third fixing hole, and the third side plate 4113 has a fourth fixing hole. A hollow second fixing post 4118 is located on the side of the third side plate 4113 facing the fourth side plate 4114. The fourth fixing hole communicates with the hollow second fixing post 4118 and the third fixing hole. Optionally, both the third and fourth fixing holes are screw holes. During installation, one end of the second fixing member is placed inside the hollow second fixing post 4118 through the third and fourth fixing holes and connected to the second fixing post 4118. This allows for the connection between the third side plate 4113 and the partition 23, while ensuring that oil does not seep into the limiting assembly 40, preventing the limiting assembly 40 from becoming stuck due to oil accumulation, thus ensuring the normal operation of the limiting assembly 40.

[0066] Thus, the limiting component 40 and the oil cup 20 are connected by a first fixing member and a second fixing member, which is applicable to oil cups 20 of various sizes and has strong versatility.

[0067] In one embodiment, see Figure 1 , Figure 3 and Figure 7 The first connector 30 includes a connecting part 31 and an insertion part 32 connected to the connecting part 31. The connecting part 31 is connected to one of the range hood body 10 and the oil cup 20, and the insertion part 32 is disposed in the receiving cavity 4116.

[0068] Further, see Figure 3 and Figure 7 The insertion part 32 is provided with a slot 321, which engages with the second locking member 42. Optionally, the first locking member 30 is a columnar structure, and the slot 321 is located in the middle of the length direction of the first locking member 30 and on its side. During installation, the insertion part 32 enters the receiving cavity 4116 through the insertion hole 4121, and at least a portion of the second locking member 42 enters the slot 321, thereby locking the first locking member 30 and the second locking member 42. In this way, the cooperation between the slot 321 and the second locking member 42 improves the firmness of the connection between the first locking member 30 and the second locking member 42 and the ease of installation.

[0069] In one embodiment, see Figure 7 The second snap-fit ​​member 42 is rotatably disposed in the receiving cavity 4116 so that the second snap-fit ​​member 42 has a snap-fit ​​position and a clearance position to avoid the insertion part 32. During the process of the insertion part 32 entering the receiving cavity 4116 from the insertion hole 4121, the insertion part 32 can squeeze the second snap-fit ​​member 42 to rotate to the clearance position. In the clearance position, the slot of the card groove 321 is opposite to the second snap-fit ​​member 42. The second snap-fit ​​member 42 can also rotate from the clearance position to the snap-fit ​​position so that the second snap-fit ​​member 42 enters the card groove 321.

[0070] It should be noted that the second latching member 42 can be rotated from the clearance position to the latching position by the second elastic reset member 43. Of course, the second latching member 42 can also be driven to rotate from the clearance position to the latching position by a drive structure.

[0071] During installation, place the oil cup 20 below the range hood body 10, aligning the insertion hole 4121 with the first snap-fit ​​member 30. Then, push the oil cup 20 upwards, causing the insertion part 32 to be inserted into the receiving cavity 4116 through the insertion hole 4121 and contact the second snap-fit ​​member 42. Continue pushing the oil cup 20 upwards, causing the insertion part 32 to press against the second snap-fit ​​member 42, making the second snap-fit ​​member 42 rotate to avoid the insertion part 32. When the insertion part 32 is inserted to a certain depth, the slot of the slot 321 is aligned with the second snap-fit ​​member 42, and the second snap-fit ​​member 42 rotates in the opposite direction, causing at least a portion of the second snap-fit ​​member 42 to enter the slot 321, thus achieving the snap-fit ​​between the first snap-fit ​​member 30 and the second snap-fit ​​member 42.

[0072] In one embodiment, see Figure 3 The insertion part 32 is provided with a slope 322, which is used to press the second latching member 42 so that the second latching member 42 rotates to avoid the insertion part 32. Specifically, the slope 322 is provided at the first end of the first latching member 30, and in the direction from the first end to the second end of the first latching member 30, the slope 322 is inclined toward the side near the slot opening of the latching groove 321. The first end and the second end of the first latching member 30 are arranged opposite to each other, the first end of the first latching member 30 is the end of the first latching member 30 that is away from the connecting part 31, and the second end of the first latching member 30 is the end of the first latching member 30 that has the connecting part 31.

[0073] When installing the oil cup 20, push the oil cup 20 upwards, and the insertion part 32 is inserted into the receiving cavity 4116 through the insertion hole 4121, with the inclined surface 322 contacting the second locking member 42. Continue to push the oil cup 20 upwards, and the inclined surface 322 presses against the second locking member 42, causing the second locking member 42 to rotate to avoid the insertion part 32. In this way, by setting the inclined surface 322, it is easy for the insertion part 32 to smoothly press the second locking member 42 to rotate, ensuring that the insertion part 32 can be inserted to a certain depth so that the first locking member 30 and the second locking member 42 can engage and cooperate.

[0074] In one embodiment, see Figure 7 and Figure 11 The inner wall of the outer casing 41 is provided with a first rotating shaft 47; specifically, the first rotating shaft 47 is located on the base plate 4115. The second snap-fit ​​member 42 is provided with a first shaft hole. Optionally, the first shaft hole is located at the first end of the second snap-fit ​​member 42. The second snap-fit ​​member 42 is sleeved on the first rotating shaft 47 through the first shaft hole, and the first rotating shaft 47 is rotatably engaged with the wall of the first shaft hole. In this way, the second snap-fit ​​member 42 can rotate about the axial direction of the first rotating shaft 47.

[0075] Further, see Figure 7The limiting component 40 also includes a fastener 471. The fastener 471 is located on the first rotating shaft 47 and is used to limit the axial movement of the second snap-fit ​​member 42 along the first rotating shaft 47. This prevents the second snap-fit ​​member 42 from disengaging from the first rotating shaft 47 and ensures the reliability of the installation of the second snap-fit ​​member 42.

[0076] Optionally, the first rotating shaft 47 is provided with an annular groove, and the first end of the second snap-fit ​​member 42 is provided in the annular groove. The fastener 471 is a snap ring, which is provided in the annular groove. One side of the snap ring abuts against the groove wall of the annular groove, and the other side of the snap ring abuts against the second snap-fit ​​member 42.

[0077] In one embodiment, the second connector 42 also has a disengaged position in which the first connector 30 is separated from the second connector 42.

[0078] Further, see Figure 6 The limiting assembly 40 also includes a pressing member 45. The pressing member 45 is movably disposed on the housing 41, with at least a portion of it located within the receiving cavity 4116. The pressing member 45 is used to push the second latching member 42 to rotate to the separated position. It is understood that the pressing member 45 is in direct contact with the second latching member 42; pressing the pressing member 45 directly pushes the second latching member 42 to rotate to the separated position. If the oil cup 20 needs to be cleaned, pressing the pressing member 45 causes it to move, thereby pushing the second latching member 42 to rotate, causing the first latching member 30 to separate from the second latching member 42. Then, pulling down the oil cup 20 allows the first latching member 30 to exit through the insertion hole 4121 outside the receiving cavity 4116, separating the first latching member 30 from the limiting assembly 40, thus allowing the oil cup 20 to be removed from the range hood body 10.

[0079] Furthermore, the fourth side plate 4114 is provided with a first mounting hole. (See reference...) Figure 7 The pressing member 45 includes a button 451 and a connecting shaft 452. The connecting shaft 452 extends along a first direction, movably passes through a first mounting hole, and is movable along the first direction. A first end of the connecting shaft 452 is located outside the receiving cavity 4116, and a second end is located inside the receiving cavity 4116. The button 451 is located at the first end of the connecting shaft 452. Because the button 451 is located outside the housing 41, it is convenient for the user to press the button 451. Because the second end of the connecting shaft 452 is located inside the receiving cavity 4116, the second end of the connecting shaft 452 can push the second latching member 42 to rotate.

[0080] Furthermore, the oil cup 20 is provided with a second mounting hole, which communicates with the first mounting hole. The button 451 is movably disposed within the second mounting hole. Under normal circumstances, the button 451 is disposed within the second mounting hole, with its outer surface flush with the outer surface of the oil cup 20. This prevents the button 451 from protruding from the oil cup 20, ensuring the neatness and aesthetics of the oil cup 20.

[0081] In one embodiment, see Figure 7 and Figure 9 The limiting assembly 40 also includes a first elastic reset member 454. One end of the first elastic reset member 454 is connected to the outer shell 41, and the other end is connected to the connecting shaft 452. The first elastic reset member 454 is used to drive the pressing member 45 to reset. When the pressing member 45 is pressed, the first elastic reset member 454 gradually compresses. When the pressing member 45 is released, the first elastic reset member 454 gradually restores its deformation to drive the pressing member 45 to reset.

[0082] Optionally, the first elastic reset element 454 may be a spring or a rubber column, etc., and is not limited thereto.

[0083] Further, see Figure 7 and Figure 9 The first elastic reset member 454 is sleeved on the connecting shaft 452. In this way, the connecting shaft 452 can guide the extension and retraction of the first elastic reset member 454, improve the stability of the extension and retraction of the first elastic reset member 454, and thus improve the reliability of the reset of the pressing member 45.

[0084] In one embodiment, see Figure 11 The inner wall of the outer casing 41 is provided with a limiting support 49. Specifically, the limiting support 49 is located on the base plate 4115. (See reference...) Figure 10 The connecting shaft 452 is provided with a limiting step 4521. A first elastic reset member 454 is disposed between the limiting support 49 and the limiting step 4521. One end of the first elastic reset member 454 is connected to the limiting support 49, and the other end is connected to the limiting step 4521. Thus, the limiting support 49 and the limiting step 4521 provide a connection position for the first elastic reset member 454, facilitating its installation.

[0085] Furthermore, the limiting support 49 is provided with a first fixing groove, and the limiting step 4521 is provided with a second fixing groove. One end of the first elastic reset member 454 is disposed in the first fixing groove, and the other end of the first elastic reset member 454 is disposed in the second fixing groove. In this way, the first fixing groove and the second fixing groove can fix the first elastic reset member 454.

[0086] In one embodiment, see Figure 7 and Figure 9The limiting assembly 40 also includes a transmission member 46. It is understood that the transmission member 46 is rotatably disposed between the second latching member 42 and the pressing member 45, with the pressing member 45 indirectly contacting the second latching member 42 via the transmission member 46. Under the push of the pressing member 45, the transmission member 46 can rotate to push the second latching member 42 to the separated position. If it is necessary to clean the oil cup 20, the pressing member 45 is pressed, causing it to move within the receiving cavity 4116. The pressing member 45 pushes the transmission member 46 to rotate, and the transmission member 46 pushes the second latching member 42 to rotate, causing the first latching member 30 to separate from the second latching member 42.

[0087] In one embodiment, see Figure 11 The inner wall of the outer casing 41 is provided with a second rotating shaft 48. Specifically, the second rotating shaft 48 is located on the base plate 4115.

[0088] Furthermore, the transmission member 46 has a second shaft hole in its middle, and the transmission member 46 is sleeved on the second rotating shaft 48 through the second shaft hole. The second rotating shaft 48 is rotatably connected to the wall of the second shaft hole. In this way, the transmission member 46 can rotate around the axial direction of the second rotating shaft 48, and at the same time, both ends of the transmission member 46 can respectively cooperate with the pressing member 45 and the second snap-fit ​​member 42.

[0089] In one embodiment, see Figure 9 The transmission component 46 has a driving end 461 and a driven end 462. The driving end 461 contacts the pressing component 45, and the driven end 462 contacts the second locking component 42. When cleaning the oil cup 20, the pressing component 45 is pressed, causing the second end of the pressing component 45 to squeeze the driving end 461, thus rotating the transmission component 46. During the rotation of the transmission component 46, the driven end 462 pushes the second locking component 42, causing the second locking component 42 to rotate relative to the first locking component 30, thus separating the first locking component 30 from the second locking component 42.

[0090] Further, see Figure 9 The end face of the active end 461 is arc-shaped. Optionally, the end face of the active end 461 is circular arc-shaped. When the pressing member 45 is pressed, the arc-shaped active end 461 rolls in contact with the pressing member 45, which reduces resistance. At the same time, the rolling friction produces less wear debris, the contact stress is evenly distributed, and the arc surface will not be worn into a flat surface and become stuck after long-term use.

[0091] Further, see Figure 9 The end face of the driven end 462 is arc-shaped. Optionally, the end face of the driven end 462 is circular arc-shaped. When the pressing member 45 is pressed, the pressing member 45 compresses the transmission member 46 to rotate, and the arc-shaped driven end 462 rolls into contact with the second locking member 42. This reduces resistance, and at the same time, the rolling friction produces less wear debris, the contact stress is evenly distributed, and the arc surface will not be worn into a flat surface and become stuck after long-term use.

[0092] In one embodiment, see Figure 9 The pressing component 45 also includes a push head 453. The push head 453 is located at the second end of the connecting shaft 452, within the receiving cavity 4116, and contacts the driving end 461 of the transmission component 46. Optionally, the push head 453 is a square pressing block, with one side of the pressing block contacting and engaging with the driving end 461.

[0093] In one embodiment, see Figure 7 and Figure 9 The limiting component 40 also includes a second elastic reset member 43. Optionally, the second elastic reset member 43 may be a spring or a rubber component, etc., and is not limited thereto.

[0094] Further, see Figure 7 and Figure 9 The second elastic reset member 43 is disposed in the accommodating cavity 4116. One end of the second elastic reset member 43 is connected to the second snap-fit ​​member 42, and the other end of the second elastic reset member 43 is connected to the outer shell 41. The second elastic reset member 43 is used to drive the second snap-fit ​​member 42 to rotate to the snap-fit ​​position.

[0095] When installing the oil cup 20, the insertion part 32 is inserted into the receiving cavity 4116 through the insertion hole 4121 and presses against the second locking member 42. Under the pressure of the insertion part 32, the second locking member 42 rotates to avoid the insertion part 32, and the second elastic reset member 43 gradually stretches. When the insertion part 32 is inserted to a certain depth, the opening of the slot 321 aligns with the second locking member 42, and the second elastic reset member 43 gradually recovers its deformation, causing the second locking member 42 to rotate in the opposite direction, so that at least a portion of the second locking member 42 enters the slot 321. Thus, under the action of the second elastic reset member 43, the second locking member 42 can be reset so that it enters the slot 321, while simultaneously improving the reliability of the engagement between the second locking member 42 and the slot 321.

[0096] When disassembling the oil cup 20, the pressing member 45 is pressed, causing it to move within the receiving cavity 4116. The pressing member 45 pushes the transmission member 46 to rotate, which in turn pushes the second locking member 42 to rotate, causing the first locking member 30 to separate from the second locking member 42. During the separation of the first locking member 30 from the second locking member 42, the second elastic reset member 43 gradually stretches. Pulling the oil cup 20 downwards causes the first locking member 30 to exit the receiving cavity 4116, separating the oil cup 20 from the range hood body 10. Then, the force applied to the pressing member 45 is removed, and the first elastic reset member 454 returns to its original shape, causing the pressing member 45 to reset. Simultaneously, the second elastic reset member 43 gradually returns to its original shape, causing the second locking member 42 to rotate to its initial position. It can be understood that the initial position of the second locking member 42 is its locking position. Optionally, the first side plate 4111 is provided with a pull ring, and the second end of the second snap-fit ​​member 42 is provided with a pull lug. One end of the second elastic reset member 43 is hooked onto the pull ring, and the other end of the second elastic reset member 43 is hooked onto the pull lug. In this way, the installation of the second elastic reset member 43 is realized.

[0097] In one embodiment, see Figure 7 , Figure 9 and Figure 11 The limiting assembly 40 also includes a limiting frame 44. The limiting frame 44 is disposed within the receiving cavity 4116. Specifically, the limiting frame 44 is connected to the second side plate 4112 and / or the bottom plate 4115. The limiting frame 44 is provided with a limiting hole 441, which extends along the second direction.

[0098] Furthermore, the second locking member 42 is rod-shaped and extends along the first direction, movably passing through the limiting hole 441. Thus, the two opposing walls of the limiting hole 441 in the second direction can limit the rotation of the second locking member 42, allowing it to rotate within a certain angle range and preventing excessive rotation.

[0099] In one embodiment, see Figure 7 and Figure 11 At least two limiting brackets 44 are provided, and the at least two limiting brackets 44 are arranged side by side in the first direction. The first locking member 30 is located between two adjacent limiting brackets 44 and engages with the second locking member 42. In this way, the two adjacent limiting brackets 44 form an assembly groove, the degree of freedom of the first locking member 30 in the first direction is constrained, the first locking member 30 is prevented from shaking, the reliability of the engagement is improved, and the risk of the first locking member 30 and the second locking member 42 becoming loose is reduced.

[0100] In one embodiment, see Figure 13The cover 412 is provided with a guide shell 4122. Specifically, the guide shell 4122 is provided on the side of the cover 412 facing the receiving cavity 4116, and the guide shell 4122 is coaxially arranged with the insertion hole 4121. The guide shell 4122 is provided with a first connecting hole and a second connecting hole, the first connecting hole communicating with the insertion hole 4121, and the second connecting hole communicating with the receiving cavity 4116. Optionally, the cross-sectional shape of the guide shell 4122 is square, circular, etc. When the oil cup 20 is installed, at least a portion of the first snap-fit ​​member 30 enters the guide shell 4122 through the insertion hole 4121 and exits from the guide shell 4122 into the receiving cavity 4116. Thus, the hollow guide shell 4122 forms a continuous guide channel. When the oil cup 20 is installed, the first snap-fit ​​part 30 slides into the receiving cavity 4116 along the guide shell 4122. The guide shell 4122 can correct the insertion angle deviation of the first snap-fit ​​part 30, realize blind insertion alignment, and reduce the assembly difficulty.

[0101] In one embodiment, see Figure 12 and Figure 13 The connection between the guide shell 4122 and the cover 412 is provided with a chamfer 4123. The chamfer 4123 is flared. When the first snap-fit ​​30 is inserted into the insertion hole 4121, the bevel of the chamfer 4123 can correct deviations such as the insertion angle of the first snap-fit ​​30, ensuring the smooth insertion of the first snap-fit ​​30.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.
