Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a pot lid assembly and a pressure cooking appliance. Background Technology

[0002] Pressure cookers can generally be divided into two categories based on how the lid and pot are assembled. One type is the separate pressure cooker, where the lid and pot are separate structures, meaning the lid can be removed from the pot. The other type is the integrated pressure cooker, where one end of the lid is rotatably connected to the pot, and the lid can be opened and closed by flipping up and down around the connection point. The lid cannot be removed from the pot.

[0003] Furthermore, for pressure cooking appliances, to ensure safe pressure build-up inside the pot, the lid and pot body must be properly locked before pressure cooking can proceed. Specifically, the lid has a locking mechanism around its perimeter, the pot body has a locking mechanism along its rim, and at least a portion of the lid can rotate relative to the pot body, allowing the locking mechanism to engage or disengage with the locking mechanism.

[0004] In integrated pressure cookers, the lid can be divided into two types based on its structure. One type includes a top cover, a liner, and an inner lid. A locking mechanism is located on the inner lid, and the lid also has a handle for rotating the inner lid. The liner has an arc-shaped track that engages with the inner lid to restrict its movement. Because the rotation of the inner lid is restricted by the track on the liner, the rotation of the inner lid is more stable in this type of appliance.

[0005] Another type of lid consists of a top cover and an inner lid, employing a linerless design. The inner lid's locking teeth are also located within the top cover, and the handle directly rotates the inner lid relative to the top cover to lock or unlock it. To ensure proper engagement between the inner and outer lid teeth, a certain gap needs to be maintained. However, this type of lid, lacking the restraint of a liner, allows the inner lid to easily move laterally during rotation. For example, when the user rotates the handle to the right, while rotating the inner lid in the same direction, it also causes the inner lid to move horizontally to the right. This reduces the gap between the left-side locking teeth of the inner lid and the left-side locking teeth of the pot. Consequently, when the user flips the lid open, the left-side locking teeth and pot teeth can easily interfere, causing them to scrape against each other. Over time, this can lead to the coating on either the inner or outer lid teeth peeling off, affecting the overall quality. In severe cases, the lid may even become stuck and unable to be opened, resulting in a poor user experience. Utility Model Content

[0006] This utility model provides a lid assembly for a pressure cooking appliance and a pressure cooking appliance to solve the problem that in a one-piece pressure cooking appliance without a liner, when the handle rotates to open the inner lid, the inner lid is prone to horizontal movement, which causes the lid teeth and pot teeth on the opposite side to interfere and scrape, thus obstructing the opening of the lid.

[0007] The technical solution adopted in this utility model is as follows: A pressure cooking appliance lid assembly includes a top cover and an inner cover located below the top cover. The lid assembly also includes a handle fixed to the inner cover. The handle is used to rotate the inner cover. The top cover has an installation opening. The handle has a handle seat located within the installation opening. The edge of the installation opening has an unlocking end and a locking end arranged radially opposite to each other. The handle can be rotated in a first direction toward the unlocking end to unlock the inner cover from the pot body. The gap between the unlocking end and the outer peripheral surface of the handle seat is smaller than the gap between the locking end and the outer peripheral surface of the handle seat.

[0008] In this invention, the handle seat passes through the mounting opening of the outer cover and is fixedly connected to the inner cover. The handle is used to control the rotation of the inner cover. When the handle is rotated towards the unlocking end, it causes the inner cover to rotate in the same direction, thus unlocking the inner cover from the pot body. Simultaneously, the horizontal distance between the handle seat and the unlocking end of the mounting opening is less than the horizontal distance between the handle seat and the locking end. This results in a smaller range of horizontal movement of the handle seat (i.e., the inner cover) towards the unlocking end when the user rotates the handle towards the unlocking end to open the lid. Once the horizontal movement of the handle seat (i.e., the inner cover) towards the unlocking end reaches the gap value between them, the handle seat and the unlocking end will form a stop, thereby limiting the horizontal movement of the inner cover. Ensure that there is an appropriate gap between the lid teeth and the pot teeth on the corresponding locking end of the inner lid, so that when the user flips and lifts the lid assembly, the lid teeth and pot teeth on that side will not interfere with each other, thereby reducing the risk of scratching and wear, ensuring the integrity of the surface coating, improving service life and overall quality. At the same time, during the opening process, the lid teeth and pot teeth around the inner lid will not interfere with each other, thereby ensuring smooth opening and reducing the possibility that the lid assembly will be stuck and unable to be opened.

[0009] The handle seat has a first seat body facing the unlocking end and a second seat body facing the locking end in the circumferential direction, and the diameter of the first seat body is larger than the diameter of the second seat body.

[0010] In this design, the handle base includes a first base and a second base. The first base faces the unlocking end and has a larger diameter, while the second base faces the locking end and has a smaller diameter. This makes at least a portion of the handle base a variable diameter structure in the circumferential direction. Consequently, the horizontal distance between the first base and the unlocking end is smaller, while the horizontal distance between the second base and the locking end is larger. This results in a smaller displacement by which the handle base can drive the inner cover to move horizontally towards the unlocking end, thus restricting the horizontal movement of the inner cover.

[0011] The extension angle of the first seat in the circumferential direction of the handle seat is not less than the rotation angle of the handle seat along the first direction.

[0012] In this design, the extension angle of the first seat corresponds to the arc length of the first seat in the circumferential direction of the handle seat. It is greater than the rotation angle of the handle seat during the opening operation, which can ensure that the first seat can always correspond to the unlocking end during the opening and rotation of the handle. That is, it maintains a small gap between the handle seat and the unlocking end, thereby forming a stable and reliable movement limit for the inner cover.

[0013] The edge of the mounting port is bent upwards or downwards to form a vertical extension section, and the height of the first base body is not less than the height of the vertical extension section.

[0014] In this design, the vertical extension increases the contact area between the edge of the mounting opening and the first seat, ensuring a stable stop between them and preventing slippage during contact. The height of the first seat is not less than the height of the vertical extension, further ensuring stable contact and reliably limiting the horizontal movement of the inner cover. This prevents misalignment between the first seat and the vertical extension due to vertical movement of the handle seat, which could lead to a loss of the limiting effect.

[0015] The first and second seats are integrally formed structures.

[0016] In this design, the first and second seats are integrally molded, which facilitates the processing and manufacturing of the handle seat and reduces the processing difficulty. On the other hand, the integral structure also makes the junction of the first and second seats more rounded and uniform. Since the handle seat is exposed on the lid and is on the outer surface of the pot lid assembly, the uniform shape also improves the overall appearance quality of the pot lid assembly, reduces the abruptness caused by different diameters, and improves the user experience.

[0017] The unlocking end is provided with a first limiting rib that protrudes radially inward along the mounting opening; or, the unlocking end is provided with a first limiting rib that protrudes radially inward along the mounting opening, and the unlocking end is provided with a second limiting rib that protrudes radially inward along the mounting opening, wherein the protruding length of the first limiting rib is greater than the protruding length of the second limiting rib.

[0018] In this design, a rib protruding towards the inside of the mounting opening is provided at the edge of the mounting opening. Due to the presence of the rib, the horizontal distance between the unlocking end and the handle seat is smaller than the horizontal distance between the locking end and the handle seat. Thus, when the handle drives the inner cover to unlock and rotate, if the inner cover undergoes a significant horizontal displacement, the handle seat can contact the first limiting rib to form a stop, ensuring that there is a suitable clearance between the cover teeth and pot teeth at the corresponding locking end of the inner cover without interference, thus guaranteeing smooth opening of the cover.

[0019] The first limiting rib has a contact end for contacting the handle seat, and the contact end is provided with a contact arc surface.

[0020] In this design, the end of the first limiting rib is an arc-shaped structure, so that when it comes into contact with the handle seat, the two make point contact or line contact, thereby reducing the contact area. While ensuring a stable and reliable contact, the frictional resistance between the two is reduced, so that when the user rotates the handle toward the unlocking end, even if the handle seat comes into contact with the first limiting rib, the user's opening operation will not be too strenuous, and the handle can still be rotated smoothly, reducing the feeling of jamming when operating the handle.

[0021] The edge of the mounting opening is bent upward or downward to form a vertical extension section. The vertical extension section has vertical ribs on the wall facing the inside of the mounting opening, and the vertical ribs are spaced apart around the circumference of the mounting opening.

[0022] During the rotation of the inner lid, the handle may tilt, meaning the two ends are at different heights. Although the tilt at the handle is small, it is amplified at the edge of the inner lid. This causes severe tilting of the inner lid, resulting in uneven engagement with the pot teeth due to the height difference, and may even cause wear on the pot teeth and lid teeth. In this design, vertical ribs are spaced out on the outer periphery of the handle base, which can cooperate with multiple areas in the circumferential direction of the handle base to keep the handle base vertical and reduce the tilting of the handle during rotation.

[0023] The handle also includes a grip portion located above the handle base, and the top surface of the cover is provided with an upwardly protruding support rib. The support rib is used to support the grip portion so that there is a gap between the grip portion and the top surface of the cover.

[0024] In this design, the supporting ribs provide upward support to the upper grip area. This prevents the handle from sagging under the weight of the inner cover after assembly, thus avoiding excessive wear between the grip and the upper surface of the cover, which would affect the opening and closing feel. Furthermore, the supporting ribs reduce the contact area between the grip and the cover, minimizing friction and making it easier to turn the handle, resulting in smoother operation and a better user experience.

[0025] This utility model also discloses a pressure cooking appliance, including a pot body and a pot lid assembly of the pressure cooking appliance. The inner lid is provided with lid teeth on its edge, and the pot body is provided with pot teeth on its rim. The inner lid can rotate relative to the pot body so that the pot teeth and lid teeth are aligned vertically to lock or misaligned vertically to unlock. Attached Figure Description

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] like Figures 1 to 3 As shown, a pressure cooking appliance lid assembly includes a top cover 1 and an inner cover 2 located below the top cover 1. The lid assembly also includes a handle 3 fixed to the inner cover 2. The handle 3 is used to rotate the inner cover 2. The top cover 1 has an installation opening 11. The handle 3 has a handle seat 31 located inside the installation opening 11. The edge of the installation opening 11 has an unlocking end 111 and a locking end 112 arranged radially opposite to each other. The handle 3 can rotate in a first direction toward the unlocking end 111 to unlock the inner cover 2 from the pot body. The gap L1 between the unlocking end 111 and the outer peripheral surface of the handle seat 31 is smaller than the gap L2 between the locking end 112 and the outer peripheral surface of the handle seat 31.

[0034] It is understandable that, such as Figure 1 As shown, the inner lid 2 has multiple downward-curving lid teeth 21 spaced along its edge, and the rim of the pot body has multiple outwardly protruding pot teeth spaced along its circumference. When the lid assembly closes the pot body, the lid teeth 21 and the pot teeth are misaligned vertically, allowing the lid teeth 21 to extend through the gaps between the pot teeth to the area below them. Then, rotating the inner lid 2 aligns the lid teeth 21 with the pot teeth, thus locking the lid. Unlocking is similar; rotating the inner lid 2 misaligns the lid teeth 21 with the pot teeth, allowing the lid assembly to be lifted.

[0035] In this invention, since the handle 3 is fixedly connected to the inner cover 2, to ensure smooth assembly and rotation, the diameter of the mounting opening 11 needs to be larger than the outer diameter of the handle base 31. Furthermore, the gap between the handle base 31 and the unlocking end 111 is the maximum horizontal displacement of the inner cover 2 towards the unlocking end 111, and the gap between the handle base 31 and the locking end 112 is the maximum horizontal displacement of the inner cover 2 towards the locking end 112. Therefore, by designing the horizontal gaps between the unlocking end 111, the locking end 112, and the handle base 31, the horizontal movement of the inner cover 2 can be limited.

[0036] In this invention, the handle base 31 passes through the mounting opening 11 of the cover 1 and is fixedly connected to the inner cover 2. The handle 3 is used to control the rotation of the inner cover 2. When the handle 3 is rotated towards the unlocking end 111, it drives the inner cover 2 to rotate in the same direction, thus unlocking the inner cover 2 from the pot body. At the same time, the horizontal distance between the handle base 31 and the unlocking end 111 of the mounting opening 11 is less than the horizontal distance between it and the locking end 112. This results in a smaller range of horizontal movement of the handle base 31, i.e., the inner cover 2, towards the unlocking end 111. Therefore, when the user operates the handle 3 to rotate towards the unlocking end 111 to open the lid, once the horizontal movement of the handle base 31, i.e., the inner cover 2, towards the unlocking end 111 reaches the gap value between them, the handle base 31 and the unlocking end 111 will form a stop, thereby limiting the horizontal movement of the inner cover 2. Ensure that there is still an appropriate gap between the cover teeth 21 on the corresponding locking end 112 side of the inner cover 2 and the pot teeth of the pot body, so that when the user flips and lifts the pot lid assembly, the cover teeth 21 and the pot teeth on this side will not interfere with each other, thereby reducing the risk of scratching and wear between the two, ensuring the integrity of the surface coating, improving service life and overall quality. At the same time, during the opening process, the cover teeth 21 and the pot teeth around the inner cover 2 will not interfere with each other, thereby ensuring the smoothness of opening the lid and reducing the possibility that the pot lid assembly will be stuck and unable to be opened.

[0037] For example, in the common design of pressure cookers, rotating handle 3 counterclockwise opens the lid; that is, the first direction is counterclockwise. At this point, as... Figures 1 to 3 As shown, the unlocking end 111 is located on the right side of the handle 3, and the locking end 112 is located on the left side of the handle 3. Of course, the unlocking direction of the handle 3 can also be set in the opposite direction, in which case the positions of the locking end 112 and the unlocking end 111 are interchanged.

[0038] To limit the horizontal movement of the handle 3 towards the unlocking end 111, the main purpose of this invention is to reduce the gap between the handle seat 31 and the mounting opening 11, thereby limiting the amount of movement of the handle seat 31, i.e., the inner cover 2. However, this invention does not limit the specific method of reducing this gap, which includes, but is not limited to, the situations listed in the following embodiments: Implementation Method 1: In this implementation method, as follows Figure 4 , Figure 7 As shown, the handle base 31 has a first base 311 facing the unlocking end 111 and a second base 312 facing the locking end 112 in the circumferential direction. The diameter D1 of the first base 311 is larger than the diameter D2 of the second base 312.

[0039] The handle base 31 includes a first base 311 and a second base 312. The first base 311 faces the unlocking end 111 and has a larger diameter, while the second base 312 faces the locking end 112 and has a smaller diameter. This makes at least a portion of the handle base 31 a variable diameter structure in the circumferential direction. As a result, the horizontal distance between the first base 311 and the unlocking end 111 is small, while the horizontal distance between the second base 312 and the locking end 112 is large. This makes the amount of displacement by which the handle base 31 can drive the inner cover 2 to move horizontally toward the unlocking end 111 smaller, thereby restricting the horizontal movement of the inner cover 2.

[0040] In this embodiment, the handle base 31 can be designed as a whole in two parts, with the first base 311 and the second base 312 spliced ​​together to form the handle base 31. That is, the cross-section of the handle base 31 is a non-circular structure, with a larger diameter on the side facing the unlocking end 111 and a smaller diameter on the side facing the locking end 112. Alternatively, the handle base 31 can be designed as a cylindrical structure to form the second base 312, and a rib structure can be provided on the surface of the handle base 31 on the side facing the unlocking end 111 to form the first base 311. The specific design is not limited here.

[0041] Preferably, such as Figure 4 , Figure 7 As shown, the extension angle α of the first seat 311 in the circumferential direction of the handle seat 31 is not less than the rotation angle of the handle seat 31 along the first direction.

[0042] The extension angle of the first seat 311 corresponds to the arc length of the first seat 311 in the circumferential direction of the handle seat 31. It is greater than the rotation angle of the handle seat 31 during the opening operation. This ensures that the first seat 311 can always correspond to the unlocking end 111 during the opening and rotation of the handle 3, that is, to maintain a small gap between the handle seat 31 and the unlocking end 111, thereby forming a stable and reliable movement limit for the inner cover 2.

[0043] Preferably, for pressure cooking appliances, the handle 3 typically rotates at an angle of 30° when the lid is unlocked. Therefore, in this embodiment, the first seat 311 extends upward at an angle α of not less than 30° around the handle seat 31. This ensures that the first seat 311 always faces the unlocking end 111 before, during, and after the lid is fully opened, thus restricting the horizontal movement of the inner lid 2 toward the unlocking end 111 throughout the entire opening process.

[0044] In a preferred embodiment, such as Figure 4 , Figure 5 , Figure 6 As shown, the edge of the mounting port 11 is bent upward or downward to form a vertical extension section 14, and the height H1 of the first base 311 is not less than the height H2 of the vertical extension section 14.

[0045] The vertical extension section 14 increases the contact area between the edge of the mounting opening 11 and the first seat 311, ensuring a stable stop between them and preventing slippage during contact. The height of the first seat 311 is not less than the height of the vertical extension section 14, further ensuring stable contact and reliably limiting the horizontal movement of the inner cover 2. This prevents misalignment between the first seat 311 and the vertical extension section 14 due to vertical movement of the handle seat 31, which would otherwise compromise the limiting effect.

[0046] Specifically, such as Figure 4 As shown, the first seat 311 can be located in a portion of the overall height of the handle base 31. In this case, the upper edge of the first seat 311 is not lower than the upper edge of the vertical extension 14, and the lower edge of the first seat 311 is not higher than the lower edge of the vertical extension 14. Of course, the first seat 311 can also completely occupy the handle base 31 in the height direction, that is, the first seat 311 extends from the bottom end to the top end of the handle base 31. In this case, the first seat 311 can necessarily cooperate with the vertical extension 14.

[0047] Preferably, such as Figure 4 As shown, the first seat 311 and the second seat 312 are integrally formed structures.

[0048] The first seat 311 and the second seat 312 are integrally formed, which on the one hand facilitates the processing and manufacturing of the handle seat 31 and reduces the processing difficulty. On the other hand, the integral structure also makes the junction of the first seat 311 and the second seat 312 more rounded and uniform. Since the handle seat 31 is partially exposed on the cover 1 and is on the outer surface of the pot lid assembly, the uniform shape also improves the overall appearance quality of the pot lid assembly, reduces the abruptness caused by different diameters, and improves the user experience.

[0049] Implementation Method 2: In this implementation method, the horizontal gap between the mounting port 11 and the handle seat 31 is controlled by structural design of the mounting port 11.

[0050] Specifically, in one embodiment, the unlocking end 111 is provided with a first limiting rib 12 that protrudes radially inward along the mounting opening 11 to reduce the horizontal gap between the handle seat 31 and the first limiting rib 12.

[0051] In another embodiment, such as Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the unlocking end 111 is provided with a first limiting rib 12 that protrudes radially inward along the mounting opening 11, and the unlocking end 111 is provided with a second limiting rib 16 that protrudes radially inward along the mounting opening 11. The protruding length of the first limiting rib 12 is greater than the protruding length of the second limiting rib 16.

[0052] A rib protruding towards the inside of the mounting opening 11 is provided along the edge of the mounting opening 11. Due to the large protrusion length of the first limiting rib 12, the horizontal distance between the unlocking end 111 and the handle seat 31 is smaller than the horizontal distance between the locking end 112 and the handle seat 31. Thus, when the handle 3 drives the inner cover 2 to unlock and rotate, if the inner cover 2 undergoes a large horizontal displacement, the handle seat 31 can contact the first limiting rib 12 to form a stop, so that there is a suitable clearance between the cover tooth 21 and the pot tooth at the corresponding locking end 112 of the inner cover 2 without interference, ensuring smooth opening of the cover.

[0053] Furthermore, such as Figure 6 As shown, the first limiting rib 12 has a contact end for contacting the handle seat 31, and the contact end is provided with a contact arc surface.

[0054] The end of the first limiting rib 12 has an arc-shaped structure, so that when it comes into contact with the handle seat 31, the two make point contact or line contact, thereby reducing the contact area. While ensuring a stable and reliable contact, it reduces the frictional resistance between the two, so that when the user rotates the handle 3 towards the unlocking end 111, even if the handle seat 31 comes into contact with the first limiting rib 12, the user's opening operation will not be too strenuous, and the handle 3 can still be rotated smoothly and silkily, reducing the feeling of jamming when operating the handle 3.

[0055] Specifically, when the first limiting rib 12 is one or more protrusions on the unlocking end 111, it is in point contact with the handle seat 31; when the first limiting rib 12 is a strip-shaped protrusion on the unlocking end 111 and extending circumferentially along the mounting opening 11, it is in line contact with the handle seat 31.

[0056] It should be noted that the above implementation methods one and two can be implemented separately or in combination. For example, the handle seat 31 can be set as a first seat 311 and a second seat 312, and the diameter of the first seat 311 is larger than that of the second seat 312. At the same time, a first limiting rib 12 is also set at the unlocking end 111 of the mounting port 11 to further reduce the gap between the two. This is not limited here.

[0057] As a preferred embodiment of this utility model, such as Figure 6As shown, the edge of the mounting opening 11 is bent upward or downward to form a vertical extension section 14. The vertical extension section 14 is provided with vertical ribs 15 on the wall surface facing the inner side of the mounting opening 11. The vertical ribs 15 are spaced apart along the circumference of the mounting opening 11.

[0058] During the rotation of the inner lid 2, the handle 3 may tilt, meaning that the two ends are at different heights. Although the tilt at the handle 3 is small, the tilt is amplified when it reaches the edge of the inner lid 2. This causes the inner lid 2 to tilt severely, resulting in uneven locking between the two ends and the pot teeth on the pot body due to the different heights. It may even cause wear on the pot teeth and lid teeth 21.

[0059] In this embodiment, vertical ribs 15 are spaced apart on the outer periphery of the handle base 31, which can cooperate with multiple areas in the circumferential direction of the handle base 31 to keep the handle base 31 in a vertical state and reduce the tilt of the handle 3 during rotation.

[0060] Preferably, such as Figure 4 , Figure 6 As shown, the handle 3 also includes a grip portion 32 located above the handle seat 31. The top surface of the cover 1 is provided with an upwardly protruding support rib 13, which is used to support the grip portion 32 so that there is a gap between the grip portion 32 and the top surface of the cover 1.

[0061] The support rib 13 provides upward support to the upper grip 32, preventing the handle 3 from sagging under the weight of the inner cover 2 after assembly. This would avoid excessive wear between the grip 32 and the upper surface of the cover 1, which would affect the feel of opening and closing the cover. Furthermore, the support rib 13 reduces the contact area between the grip 32 and the cover 1, resulting in less friction and making it easier to turn the handle 3, thus improving the user experience.

[0062] Preferably, such as Figure 6 As shown, the support rib 13 is located at the edge of the mounting opening 11.

[0063] Preferably, the top of the support rib 13 is provided with an arc surface to reduce its contact area with the grip part 32 and reduce the frictional resistance when the operating handle 3 is rotated.

[0064] This utility model also discloses a pressure cooking appliance, including a pot body and a pot lid assembly of the pressure cooking appliance. The inner lid 2 is provided with a lid tooth 21 on its edge, and the pot body is provided with a pot tooth on its rim. The inner lid 2 can rotate relative to the pot body so that the pot tooth and the lid tooth 21 are aligned vertically to lock or misaligned vertically to unlock.

[0065] Preferably, a connecting arm is provided at the rear end of the lid assembly, and a connecting seat is provided at the rear end of the pot body. One end of the connecting arm is connected to the connecting seat through a shaft and hole, and the other end is connected to the two through a coupling. The mating structure at both ends serves as the rotation center of the lid assembly. The coupling does not output any energy; it only provides damping, giving the user a good damping feel when opening and closing the lid, preventing the machine from tipping over due to excessive force when opening the lid assembly, and preventing the lid assembly from falling rapidly and violently colliding with the pot body when closing the lid.

[0066] Of course, a torsion spring can also be used at the connection between the lid assembly and the pot body so that the lid assembly can spring open upwards under the action of the torsion spring when the user opens the lid. This is not a limitation.

[0067] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0068] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0069] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
