Description

[0001] This application claims priority to the invention patent application filed on December 29, 2023, with application number 202311873884.7, entitled "Cooking Utensils". Technical Field

[0002] This utility model relates to the field of small household appliances, and more specifically, to a cover assembly and a cooking utensil having the same. Background Technology

[0003] In related technologies, cooking appliances include a pot body and a lid. To ensure the lid can be stably attached to the pot body, a double locking structure is provided between the lid and the pot body. The first locking structure is a locking structure formed by the locking mechanism on the lid and the pot body inside the pot body through the locking teeth on the lid and the locking mechanism on the pot body; the second locking structure is a locking structure formed by the locking mechanism on the lid and the locking mechanism on the pot body.

[0004] The first locking mechanism requires rotating the handle on the lid to unlock, while the second locking mechanism requires pressing a button on the pot body. Therefore, when a user needs to open the lid, they must first rotate the handle and then press the button to unlock, which is rather complicated and results in a poor user experience.

[0005] In related technologies, Chinese utility model patent application number 202221673921.0 provides a cooking appliance that solves the problem of complicated operation when opening the lid. This patent includes a lid-opening button, a drive lever, a transmission lever, a transmission plate, and a clamping structure. By pressing the lid-opening button, the button applies force to the drive lever, causing the hook of the drive lever to separate from the lid's locking mechanism. The hook of the drive lever no longer restricts the transmission lever, allowing the transmission rod to move forward. The clamping structure then switches to the unlocked state, achieving dual unlocking with just the press of the lid-opening button, simplifying the user's operation.

[0006] In the aforementioned patented solution, the cap tooth reset component applies a reset force to the caliper structure via a transmission plate, ensuring the caliper structure remains in the unlocked state when the cap is opened. The cap tooth reset component is a compression spring, sleeved on the connecting shaft and fixed in position by a vertical plate. In other embodiments, the compression spring is replaced with a tension spring, which is located on the rear side of the transmission plate. In this case, the tension spring is secured using fasteners, such as screws.

[0007] The above method of fixing the spring with fasteners makes assembly cumbersome and inefficient. Utility Model Content

[0008] The main purpose of this utility model is to provide a cover assembly and a cooking appliance having the same, so as to solve the problems of cumbersome assembly and low efficiency in related technologies.

[0009] To achieve the above objectives, according to one aspect of the present invention, a lid assembly is provided, which is disposed on a pot body. The lid assembly includes: a lid body with a locking platform at its front; a locking mechanism movably disposed on the lid body and having a locked state for locking the pot body and an unlocked state for unlocking the pot body; a transmission mechanism including a rotating member rotatably disposed on the lid body and a linkage member disposed between the rotating member and the locking mechanism, wherein the rotating member can drive the locking mechanism to switch between the locked state and the unlocked state through the linkage member when rotating; and a reset member disposed between the lid body and the linkage member, wherein the reset member applies a reset force to the linkage member to keep the locking mechanism in the unlocked state; wherein the linkage member is provided with a first hook connecting to a first end of the reset member, and / or the lid body is provided with a second hook connecting to a second end of the reset member.

[0010] By applying the technical solution of this utility model, the locking mechanism has a locked state for locking the pot body and an unlocked state for unlocking the pot body. When the rotating part rotates, it can drive the locking mechanism to switch between the locked and unlocked states through the linkage part. The reset part applies a reset force to the linkage part to keep the locking mechanism in the unlocked state. In this application, the reset part is disposed between the lid body and the linkage part. The linkage part is provided with a first hook connecting the first end of the reset part, and / or the lid body is provided with a second hook connecting the second end of the reset part. Through the above structure, the first end of the reset part is assembled with the linkage part through the first hook, and / or the second end of the reset part is assembled with the lid body through the second hook. The hook assembly method is simple and convenient to operate, effectively improving assembly efficiency. Therefore, the technical solution of this application effectively solves the problems of cumbersome assembly and low efficiency in related technologies.

[0011] Furthermore, the first end of the reset component is provided with a first connecting ring that mates with the first hook, and the second end of the reset component is provided with a second connecting ring that mates with the second hook. The first connecting ring can be hooked onto the first hook, and the second connecting ring can be hooked onto the second hook, simplifying operation and further improving assembly efficiency. Moreover, the first and second connecting rings are easy to manufacture and have low cost.

[0012] Furthermore, when the cover body is provided with a second hook connecting the second end of the reset component, the second hook is located on the side of the linkage component away from the locking platform. This structural arrangement is reasonable and effectively avoids interference between the second hook and the reset component and other moving parts.

[0013] Furthermore, the second hook includes a mounting base, a hook body disposed on the side of the mounting base away from the linkage, and a clearance slope disposed on the side of the mounting base facing the linkage, the clearance slope being gradually inclined towards the linkage from top to bottom. When the second end of the reset member is connected to the second hook, the aforementioned clearance slope can guide the second end of the reset member, enabling the reset member to be quickly installed in place.

[0014] Furthermore, the mounting base includes a first base body and a second base body disposed above the first base body, with a support platform formed between the first and second base bodies. This support platform supports the reset component, preventing the second end of the reset component from easily moving up and down.

[0015] Furthermore, the reset element is a tension spring. Tension springs are simple and stable in structure. They provide tension to the linkage element towards the rear of the cover body.

[0016] Furthermore, the pot body includes an inner pot with a flanged rim. The linkage includes a sliding plate with a groove. The locking mechanism includes a mounting plate and a clamp mounted on the mounting plate. The clamp can lock or unlock the flanged rim. The sliding plate moves perpendicular to the mounting plate. A limiting post is provided on the mounting plate, passing through the groove. The clamp cooperates with the flanged rim to achieve locking or unlocking, resulting in a simple structure and good movement stability.

[0017] Furthermore, the skateboard includes a board body and an outwardly protruding wing plate disposed on the board body, with both the sliding groove and the first hook disposed on the outwardly protruding wing plate. Distributing both the sliding groove and the first hook on the outwardly protruding wing plate makes the skateboard structure compact and easy to manufacture.

[0018] Furthermore, the linkage component and the first hook are integrally molded, and the cover body and the second hook are integrally molded. These integrally molded structures are easy to manufacture and have lower costs.

[0019] According to another aspect of this utility model, a cooking utensil is provided, including a lid assembly, which is the lid assembly described above. Since the lid assembly can solve the problems of cumbersome assembly and low efficiency in related technologies, the cooking utensil having the lid assembly can also solve the aforementioned problems.

[0053] like Figure 1 , Figure 2b as well as Figure 6 As shown, in this embodiment, the lid assembly 20 is placed on the pot body 10. The lid assembly includes: a lid body 21, a locking mechanism 30, a transmission mechanism 50, and a reset member 53. The front part of the lid body 21 is provided with a locking platform 21a. The locking mechanism 30 is movably disposed on the lid body 21 and has a locked state for locking the pot body 10 and an unlocked state for unlocking the pot body. The transmission mechanism 50 includes a rotating member 51 rotatably disposed on the lid body 21 and a linkage member 52 disposed between the rotating member 51 and the locking mechanism 30. When the rotating member 51 rotates, it can drive the locking mechanism 30 to switch between the locked state and the unlocked state through the linkage member 52. The reset member 53 is disposed between the lid body 21 and the linkage member 52. The reset member 53 applies a reset force to the linkage member 52 to keep the locking mechanism 30 in the unlocked state. The linkage member 52 is provided with a first hook 525 connecting the first end of the reset member 53, and the lid body 21 is provided with a second hook 213 connecting the second end of the reset member 53.

[0054] Applying the technical solution of this embodiment, the locking mechanism 30 has a locked state for locking the pot body 10 and an unlocked state for unlocking the pot body. When the rotating member 51 rotates, it can drive the locking mechanism 30 to switch between the locked state and the unlocked state through the linkage member 52. The reset member 53 applies a reset force to the linkage member 52 to keep the locking mechanism 30 in the unlocked state. In this embodiment, the reset member 53 is disposed between the lid body 21 and the linkage member 52. The linkage member 52 is provided with a first hook 525 connecting the first end of the reset member 53, and the lid body 21 is provided with a second hook 213 connecting the second end of the reset member 53. With the above structure, the first end of the reset member 53 is assembled with the linkage member 52 through the first hook 525, and the second end of the reset member 53 is assembled with the lid body 21 through the second hook 213. The hook assembly method is simple and convenient to operate, effectively improving assembly efficiency. Therefore, the technical solution of this embodiment effectively solves the problems of cumbersome assembly and low efficiency in related technologies.

[0055] In an embodiment not shown in the figure, the first hook can be provided only on the linkage, or the second hook can be provided only on the cover body. In this case, one end of the reset component is assembled by the hook, while the other end can be assembled in other ways, such as still by screws. This method is still simpler and more efficient than assembling the reset component by screws on both ends.

[0056] like Figure 6 and Figure 10As shown, the first end of the reset member 53 is provided with a first connecting ring 531 that mates with the first hook 525, and the second end of the reset member 53 is provided with a second connecting ring 532 that mates with the second hook 213. The first connecting ring 531 can be hooked onto the first hook 525, and the second connecting ring 532 can be hooked onto the second hook 213, simplifying operation and further improving assembly efficiency. Furthermore, the first connecting ring 531 and the second connecting ring 532 are easy to manufacture and have low cost.

[0057] like Figure 6 As shown, the second hook 213 is located on the side of the linkage 52 away from the locking plate portion 21a. The above structural arrangement is reasonable and effectively avoids interference between the second hook 213 and the reset member 53 and other moving parts.

[0058] like Figure 7 and Figure 8 As shown, the second hook 213 includes a mounting base 2131, a hook body 2132 disposed on the side of the mounting base 2131 away from the linkage 52, and a clearance slope 2133 disposed on the side of the mounting base 2131 facing the linkage 52. The clearance slope 2133 is gradually inclined towards the linkage 52 from top to bottom. When the second end of the reset member 53 is connected to the second hook 213, the clearance slope 2133 can guide the second end of the reset member 53, so that the reset member 53 can be quickly installed in place.

[0059] like Figure 7 and Figure 8 As shown, the mounting base 2131 includes a first base body and a second base body disposed above the first base body, with a support platform 2134 formed between the first base body and the second base body. The support platform 2134 can support the reset member 53, making it less likely for the second end of the reset member 53 to move up and down.

[0060] like Figure 6 and Figure 10 As shown, in this embodiment, the reset member 53 is a tension spring. The tension spring has a simple and stable structure. It can provide a pulling force to the linkage member 52 towards the rear of the cover body 21. Of course, as a feasible implementation, the reset member can also be a silicone component or similar structure.

[0061] like Figure 1 and Figure 3dAs shown, in this embodiment, the pot body 10 includes an inner pot 11 with a flanged rim 111. The linkage 52 includes a sliding plate with a groove 521. The locking mechanism 30 includes a mounting plate 31 and a clamp 32 mounted on the mounting plate 31. The clamp 32 can lock or unlock the flanged rim 111. The sliding plate moves perpendicular to the moving direction of the mounting plate 31. A limiting post 311 is provided on the mounting plate 31 and passes through the groove 521. The sliding plate moves along the front-back direction of the cover assembly 20, and the mounting plate 31 moves along the left-right direction of the cover assembly 20. The clamp 32 cooperates with the flanged rim 111 to lock or unlock, resulting in a simple structure and good movement stability.

[0062] like Figure 9 As shown, the skateboard includes a board body 526 and an outwardly protruding wing plate 527 disposed on the board body 526. A groove 521 and a first hook 525 are both disposed on the outwardly protruding wing plate 527. By disposing the groove 521 and the first hook 525 on the outwardly protruding wing plate 527, the skateboard structure becomes compact and easy to manufacture.

[0063] In a preferred embodiment, the linkage 52 and the first hook 525 are integrally formed, and the cover body 21 and the second hook 213 are integrally formed. The aforementioned integrally formed structure is easy to manufacture and has a lower cost.

[0064] like Figure 1 As shown, the cover assembly of this embodiment also includes a top cover 25 disposed above the cover body 21 and an inner cover 23 disposed below the cover body 21. In order to improve the movement stability of the locking mechanism 30, a metal fixing plate 22 is provided below the cover body 21, and the locking mechanism 30 is mounted on the metal fixing plate 22.

[0065] According to another aspect of this utility model, a cooking utensil is provided, including a lid assembly, which is the lid assembly described above. Since the lid assembly can solve the problems of cumbersome assembly and low efficiency in related technologies, the cooking utensil having the lid assembly can also solve the aforementioned problems.

[0066] The following section will provide a detailed description of the cooking utensil design in conjunction with the accompanying drawings.

[0067] like Figure 1 As shown, the cooking appliance in this embodiment includes: a pot body 10, a lid assembly 20, a locking mechanism 30, a buckle mechanism 40, and a transmission mechanism 50.

[0068] The lid assembly 20 is closably mounted on the pot body 10. The lid assembly 20 includes a lid body 21, the rear of which is hinged to the pot body 10. The front of the lid body 21 is provided with a locking part 21a. The lid assembly 20 has an open state and a closed state.

[0069] The locking mechanism 30 is movably mounted on the lid body 21 and has a locked state for locking the pot body 10 and an unlocked state for unlocking the pot body 10.

[0070] The latching mechanism 40 is rotatably mounted on the pot body 10. The latching mechanism 40 has a double latching state and a release state that cooperate with the latching platform 21a.

[0071] The transmission mechanism 50 includes a rotating member 51 (also known as a swing rod) rotatably mounted on the cover assembly 20 and a linkage member 52 disposed between the rotating member 51 and the locking mechanism 30. The latching mechanism 40 can drive the rotating member 51 to rotate.

[0072] When the cover assembly 20 is in the closed state, the latching mechanism 40 switches from the double latching state to the unlocking state when it is subjected to force; when the cover assembly 20 switches from the open state to the closed state, the cover assembly 20 drives the latching mechanism 40 to switch from the unlocking state to the double latching state.

[0073] When the latching mechanism 40 is in a double-locking state, the latching mechanism 40 is locked to the latching platform 21a. The latching mechanism 40 abuts against the rotating member 51 and pulls the linkage member 52 to keep the locking mechanism 30 in the locked state. When the latching mechanism 40 is in the unlocked state, the latching mechanism 40 is separated from the latching platform 21a. The latching mechanism 40 releases the rotating member 51 and the locking mechanism 30 remains in the unlocked state. When the latching mechanism 40 drives the rotating member 51 to rotate, the part of the latching mechanism 40 connected to the latching platform 21a can remain relatively stationary. The latching mechanism 40 continues to rotate and then switches to the unlocked state.

[0074] In the technical solution of the embodiment, the latching mechanism 40 can cooperate with the latching platform 21a and the locking mechanism 30. The latching mechanism 40 has a dual latching state and a dislodgement state, which can realize dual locking and unlocking between the cover assembly 20 and the pot body 10. When the latching mechanism 40 has a dual latching state, as shown... Figures 2a-2d As shown, the latching mechanism 40 engages with the latching platform 21a, and simultaneously, the locking mechanism 30 is in a locked state, doubly locking the lid assembly 20 and the pot body 10. In this state, the cooking appliance can perform pressure cooking. When the latching mechanism 40 is in the unlocked state... Figures 4a-4dAs shown, the latching mechanism 40 separates from the latching platform 21a, while the locking mechanism 30 is in the unlocked state, unlocking the lid assembly 20 and the pot body 10. At this time, the lid assembly 20 switches from the closed state to the open state. In this embodiment, when the latching mechanism 40 drives the rotating member 51 to rotate, the part connected to the latching mechanism 40 and the latching platform 21a can remain relatively stationary. The latching mechanism 40 continues to rotate and then switches to the unlocked state. In the prior art, for schemes where the latching mechanism cooperates with both the latching platform and the locking mechanism, during the movement of the locking mechanism, the lid assembly moves upward relative to the pot body. This makes the unlocking process of the locking mechanism susceptible to interference from other components, resulting in difficult pressing, unsmooth opening of the lid, or even difficulty. When the latching mechanism 40 drives the rotating component 51 to rotate, the latching mechanism 40 remains engaged with the latching platform 21a and thus remains stationary. At this time, the position of the lid assembly 20 relative to the pot body 10 remains unchanged. In this state, the latching mechanism 40 continues to rotate and switches to the unlocked state. That is, the latching mechanism 40 can release the rotating component 51 at the same time as or before separating from the latching platform 21a, causing the locking mechanism 30 to switch from the locked state to the unlocked state. In this way, the movement of the locking mechanism 30 will not interfere with other components inside the lid assembly 20, making the movement smoother and improving the smoothness of opening or closing the lid assembly 20. Therefore, the technical solution of this embodiment can solve the problem in the related art where pressing is difficult during the opening process, resulting in an unsmooth opening of the lid or even an inability to open the lid.

[0075] In this embodiment, the latching mechanism 40 also has a separate latching state, such as... Figures 3a-3d As shown, when the latching mechanism 40 is in the standby state, the latching mechanism 40 latches with the latching table 21a, the latching mechanism 40 releases the rotating member 51 and the locking mechanism 30 switches from the locked state to the unlocked state and remains in the unlocked state.

[0076] When the latching mechanism 40 is in the standby state, the latching mechanism 40 is engaged with the latching platform 21a. At the same time, the locking mechanism 30 is in the unlocked state, and the cover assembly 20 and the pot body 10 are locked separately. This state is a transitional state, and the cover assembly 20 is in this state for a very short time. This state facilitates the smoothness of opening or closing the cover assembly 20.

[0077] The following will describe the process of closing and opening the lid of the cooking appliance in Example 1.

[0078] The process of closing the lid of the cooking appliance in Example 1 is as follows:

[0079] Phase 1: As Figures 4a to 4eThe inclined surface of the lower surface of the clamping section 21a causes the first latch 41 to move, and at the same time drives the second latch 42 to move. At this time, the clamp 32 is in a fully open state, the limiting post 311 is in the initial position, and the first distance between the clamp 32 and the pot opening flange 111 is the L3 design gap.

[0080] Phase Two: As Figures 3a to 3e When the cover assembly 20 reaches the set position, the second latch 42, under the action of the second reset member 45, resets and latches onto the latching plane 21b of the latching portion 21a (see reference). Figure 11 This allows the pot body 10 to be fastened together with the lid assembly 20, ensuring that the lid assembly will not pop open or shake. At this time, the first buckle 41 does not touch the rotating part 51, the slide plate does not move, the caliper 32 is in the fully open state, and the limit post 311 is in the initial position.

[0081] Furthermore, the first buckle 41 is fastened to the fastening plane 21b of the clamping platform 21a. The first buckle 41 triggers the rotating member 51, and at the same time, it can drive the sliding plate of the linkage shaft 524 to move, forcing the caliper 32 to move, and the limiting post 311 to move to the second position.

[0082] When the limiting post 311 moves from the initial position to the second position, there is still a distance between the caliper 32 and the pot flange 111 to prevent the caliper 32 from contacting the pot flange 111. The second distance between the two is L4, where L4 < L3.

[0083] Phase Three: As Figures 2a to 2d The first buckle 41 contacts the bottom end of the rotating part 51, causing it to rotate and forcing the slide plate to slide, so that the clamp 32 clamps the pot opening flange 111, and the limiting post 311 is in the third position; the force F of the first reset part 44 is greater than the force f of the reset part 53.

[0084] The process of opening the lid of the cooking appliance in Example 1 is as follows:

[0085] Phase 1: As Figures 2a to 2d The limiting post 311 is in the third position, and the caliper 32 is located below the flange 111 of the pot opening;

[0086] Phase Two: As Figures 3a to 3e Push the unlocking operation unit 60 to drive the first buckle 41 to move. At the same time, the reset part 53 pulls the slide plate to drive the caliper 32 to move. When the limit post 311 moves to the second position, the second buckle 42 contacts the first buckle 41 (specifically, the first hook 412 of the first buckle 41 contacts the second hook 422 of the second buckle 42). The second buckle 42 is still fastened on the fastening plane 21b. At this time, the caliper 32 is completely disengaged from the pot opening flange 111.

[0087] Phase Three: As Figures 4a to 4eThe first buckle 41 drives the second buckle 42 to move, causing the second buckle 42 to disengage from the fastening plane 21b, and the cover assembly 20 opens, completing the opening of the cover.

[0088] It should be noted that in other embodiments, there may be no separate latching state. When the second latch is stationary, the movement of the first latch may prevent the locking mechanism from being fully unlocked. When the first latch is in a linked rotation state, the first latch continues to drive the second latch to move. At the same time or before the second latch separates from the latching platform, the locking mechanism continues to complete the remaining unlocking stroke.

[0089] like Figure 1 As shown, the cooking appliance in this embodiment also includes an unlocking operation part 60, which is movably mounted on the pot body 10. The unlocking operation part 60 engages with the latching mechanism 40. When the lid assembly 20 needs to be opened, the user presses the unlocking operation part 60, which drives the latching mechanism 40 to switch from a double-locking state to a single-locking state, and then to an unlocking state. In this process, the locking mechanism 30 is unlocked first, and then the latching mechanism 40 is separated from the latching platform 21a, ultimately opening the lid assembly 20. Preferably, the unlocking operation part 60 is a lid-opening button, mounted on the pot body 10 via a fixing ring 61. The unlocking operation part 60 pushes against the bottom end of the latching mechanism 40.

[0090] In this embodiment, as Figures 1 to 5As shown, the latching mechanism 40 includes a first latch 41 and a second latch 42, both of which are rotatably mounted on the pot body 10. When the latching mechanism 40 is in a double latching state, the second latch 42 latches with the latching platform 21a, and the first latch 41 abuts against the rotating member 51 and pulls the linkage member 52 to keep the locking mechanism 30 in a locked state. When the latching mechanism 40 is in a single latching state, the second latch 42 latches with the latching platform 21a, the first latch 41 releases the rotating member 51, and the locking mechanism 30 switches from the locked state to the unlocked state and remains in the unlocked state. When the latching mechanism 40 is in a de-latching state, the second latch 42 separates from the latching platform 21a, the first latch 41 releases the rotating member 51, and the locking mechanism 30 remains in the unlocked state. The first latch 41, in conjunction with the rotating member 51 and the linkage member 52, controls the locking and unlocking of the locking mechanism 30. The second latch 42 engages or disengages with the locking platform 21a. The movement of the locking mechanism 30 occurs when the second latch 42 engages with the locking platform 21a. Thus, during the movement of the locking mechanism 30, the lid assembly 20 does not move upwards relative to the pot body 10, ensuring that the locking and unlocking processes of the locking mechanism 30 are not interfered with by other components. During the opening process, after the locking mechanism 30 has finished moving, the first latch 41 drives the second latch 42 to rotate, causing the second latch 42 to disengage from the locking platform 21a. During the closing process, after the second latch 42 engages with the locking platform 21a, the first latch 41 rotates, and the rotating member 51 and the linkage member 52 work together to drive the locking mechanism 30 to achieve locking.

[0091] like Figure 1 As shown, the cooking appliance also includes a first reset member 44 disposed between the pot body 10 and the first latch 41, and a second reset member 45 disposed between the pot body 10 and the second latch 42. The first reset member 44 enables the first latch 41 to remain in a vertical position, and the second reset member 45 enables the second latch 42 to remain in a vertical position. When the lid assembly 20 is in the closed position, the first latch 41 abuts against the rotating member 51 under the elastic force of the first reset member 44, and the second latch 42 is engaged with the locking platform 21a under the elastic force of the second reset member 45. Both the first reset member 44 and the second reset member 45 are torsion springs.

[0092] The opening method of this application is not limited to the latching mechanism 40 mentioned in the above embodiments, which includes a first latch 41 and a second latch 42. The opening method can also be the method mentioned in Chinese Utility Model Patent Application No. 202221673921.0. Specifically, that patent includes a latching mechanism with a hook-shaped drive lever. The same latch engages with both the caliper structure and the latching platform. The latch can simultaneously unlock the caliper and separate the latch from the latching platform, or simultaneously lock the caliper and engage the latch with the latching platform. The cover assembly of the above embodiments can also be used in the above structure to solve the problems of cumbersome assembly and low efficiency in related technologies.

[0093] The cooking appliance in this application is a pressure cooker, but it can also be a rice cooker, slow cooker, frying machine, food processor, or other appliances with other functions.

[0094] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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 on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0095] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0096] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0097] The above description is merely a preferred embodiment of this utility model and is not intended to limit the 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 principles of this utility model should be included within the protection scope of this utility model.
