Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a dust box and cleaning equipment. Background Technology

[0002] Cleaning equipment includes robotic vacuum cleaners, floor scrubbers, and multi-functional cleaning stations. Existing cleaning equipment typically includes a dustbin connected to a fan. The fan creates negative pressure within the dustbin, allowing it to collect debris and dirt from the surface to be cleaned. The dustbin usually has a filter component inside the dustbin, which filters the material entering the fan.

[0003] However, with existing dust boxes, after the filter components are removed and disposed of, users may forget to reinstall the filter components inside the dust box, resulting in contamination of the fan connected to the dust box. Utility Model Content

[0004] The main objective of this application is to provide a dust box and cleaning device to at least solve the problem in the prior art where users easily forget to install the filter components in the dust box.

[0005] According to one aspect of this application, a dust box is provided, comprising:

[0006] The main body includes a box and a cover. The box has a pouring opening, and the cover has a first position that covers and seals the pouring opening, and a second position that opens the pouring opening.

[0007] A filter element, which is detachably mounted to the cover;

[0008] A leak-proof assembly is disposed on the cover body. The leak-proof assembly has a third position that protrudes from the outer edge of the cover body to prevent the cover body from covering the pouring opening, and a fourth position that is closed to the inner side of the cover body so that the cover body can cover the pouring opening.

[0009] When the filter component is separated from the cover, the leak-proof assembly is in the third position; when the filter component is installed on the cover, the filter component moves the leak-proof assembly from the third position to the fourth position.

[0010] Furthermore, the leak-proof assembly includes a blocking member and an elastic member. The blocking member is movably disposed on the cover, and the elastic member is disposed between the blocking member and the cover, and the elastic member abuts against the blocking member.

[0011] When the filter component is separated from the cover, the elastic member causes the blocking member to protrude from the outer edge of the cover. When the filter component is installed on the cover, the filter component abuts against the blocking member, and the external force applied by the filter component to the blocking member overcomes the external force applied by the elastic member to the blocking member, so that the blocking member retracts to the inner side of the cover.

[0012] Furthermore, the blocking member includes a push rod rotatably disposed on the cover, the push rod having a first end and a second end extending in opposite directions, the second end of the push rod being located inside the cover, the rotation center of the push rod being located between the first end and the second end, and the first end of the push rod abutting against the elastic member;

[0013] When the filter component is installed on the cover, the filter component abuts against the second end of the top rod, so that the first end of the top rod rotates and retracts into the inner side of the cover. When the filter component is separated from the cover, the first end of the top rod is subjected to the elastic force applied by the elastic element, so that the first end of the top rod rotates and protrudes out of the outer edge of the cover.

[0014] Furthermore, the top rod has a bent section, which includes a first section and a second section. The first section extends in a direction away from the rotation center of the top rod, and the second section is connected to the first section, with a predetermined angle between the second section and the first section. The second section is used to abut against the filter component.

[0015] Furthermore, the second segment has an inclined surface on the side facing away from the cover, and the distance from the inclined surface to the cover gradually decreases along the direction of the second segment away from the first segment; and / or,

[0016] A reinforcing rib is provided between the first segment and the second segment.

[0017] Furthermore, the elastic element includes a torsion spring, the first end of which abuts against the cover, and the second end of which abuts against the blocking element.

[0018] Furthermore, the cover is provided with a plurality of stop portions at intervals, and the blocking member is at least partially movably disposed between two of the stop portions. When the blocking member protrudes from the outer edge of the cover, the blocking member abuts against one of the stop portions. When the blocking member is retracted to the inner side of the cover, the blocking member abuts against the other of the stop portions.

[0019] Furthermore, an installation groove is provided on the side of the cover near the box body, and the filter component is detachably installed in the installation groove. A first connecting part is provided in the installation groove, and a second connecting part adapted to the first connecting part is provided on the filter component. The first connecting part and the second connecting part cooperate to install the filter component in the installation groove. One of the first connecting part and the second connecting part includes a connecting rib, and the other includes a connecting groove.

[0020] Furthermore, the connecting ribs include multiple ribs, which are spaced apart on the inner wall of the mounting groove; the connecting grooves include multiple grooves, which are spaced apart on the outer wall of the filter component; and each connecting groove corresponds one-to-one with each connecting rib; and / or,

[0021] The connecting rib protrudes from the inner wall of the mounting groove. The side of the connecting rib facing away from the bottom surface of the mounting groove has a first guide surface. Along the protrusion direction of the connecting rib, the distance from the first guide surface to the bottom surface of the mounting groove gradually decreases; and / or,

[0022] The connecting rib protrudes from the inner wall of the mounting groove. The side of the connecting rib closest to the bottom surface of the mounting groove has a second guide surface. Along the protrusion direction of the connecting rib, the distance from the second guide surface to the bottom surface of the mounting groove gradually increases.

[0023] On the other hand, this application also provides a cleaning device, which includes the dust box described above.

[0024] Compared to existing technologies, the dustbin of this application is further equipped with a leak-proof assembly. When the user needs to clean, replace, or otherwise treat the filter component, after removing the filter component from the cover, the leak-proof assembly is in the third position, at which point the cover cannot be placed over the pouring spout, serving as a reminder to the user to install the filter component back on the cover. After the user installs the filter component back on the cover, the leak-proof assembly moves to the fourth position under the action of the filter component, at which point the leak-proof assembly is located inside the cover, allowing the cover to be placed over the pouring spout. This structure prevents users from forgetting to install the filter component, thus avoiding the problem of garbage or stains contaminating the cleaning equipment. Attached Figure Description

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0042] See Figures 1 to 11 As shown, according to an embodiment of this application, a cleaning device is provided, which includes a dust box, a main body 10, a filter component 20, and a leak-proof assembly 30.

[0043] The main body 10 includes a box body 11 and a cover 12. The box body 11 has a pouring opening 111. The cover 12 has a first position where it covers and seals the pouring opening 111, and a second position where the pouring opening 111 is open. A filter component 20 is detachably installed on the cover 12. An anti-leakage assembly 30 is disposed on the cover 12. The anti-leakage assembly 30 has a third position where it protrudes from the outer edge of the cover 12 to prevent the cover 12 from covering the pouring opening 111, and a fourth position where it closes to the inner side of the cover 12 so that the cover 12 can cover the pouring opening 111. When the filter component 20 is separated from the cover 12, the anti-leakage assembly 30 is in the third position. When the filter component 20 is installed on the cover 12, the filter component 20 moves the anti-leakage assembly 30 from the third position to the fourth position.

[0044] Specifically, the housing 11 has a receiving cavity, and the cleaning equipment also includes a fan. The main body 10 has an inlet 112 and a suction port 123, both of which are connected to the receiving cavity. The fan applies suction to the suction port 123, creating a negative pressure at the inlet 112, so that garbage or stains on the surface to be cleaned by the cleaning equipment can be sucked into the suction port 123. A filter component 20 is provided on the cover 12 to filter the airflow entering the fan from the suction port 123, preventing garbage or stains from entering the fan and contaminating it. In addition, the housing 11 has a pouring spout 111. When the cover 12 is in the second position, the user can pour out the garbage or stains collected in the housing 11 through the pouring spout 111.

[0045] Unlike existing technologies, this embodiment also includes a leak-proof assembly 30 on the dust box. When the user needs to clean, replace, or otherwise treat the filter element 20, after removing the filter element 20 from the cover 12, the leak-proof assembly 30 is in the third position. At this time, the cover 12 cannot be placed over the pouring opening 111, serving as a reminder to the user to install the filter element 20 on the cover 12. After the user installs the filter element 20 on the cover 12, the leak-proof assembly 30 moves to the fourth position under the action of the filter element 20. At this time, the leak-proof assembly 30 is located inside the cover 12, and the cover 12 can be placed over the pouring opening 111. This structure prevents users from forgetting to install the filter element 20, thus avoiding the problem of garbage or stains contaminating the cleaning equipment. In addition, it is worth mentioning that in some related technologies, the filter component 20 is set inside the housing 11. During the dust box assembly process, the filter component 20 is first installed in the housing 11, and then the cover 12 is closed. If the anti-leakage assembly 30 of this application is installed in this structure, there will be a defect. After the filter component 20 is installed on the housing 11, every time the cover 12 is needed to close the housing 11, the anti-leakage assembly 30 on the cover 12 needs to interfere with the filter component 20 before the cover 12 can be closed on the housing 11. In other words, every time the cover 12 is closed on the housing 11, there will be resistance between the anti-leakage assembly 30 and the filter component 20, making it difficult for the cover 12 to be closed on the housing 11. In this application, the filter element 20 is installed on the cover 12. The filter element 20 is installed on the cover 12 before the box 11 is placed on it. After the cover 12 is placed on the box 11, there is no resistance between the cover 12 and the box 11, allowing the cover 12 to be quickly placed on the box 11. In this embodiment, the filter element 20 can be a HEPA filter.

[0046] Furthermore, the leak-proof assembly 30 includes a blocking member 31 and an elastic member 32. The blocking member 31 is movably disposed on the cover 12, and the elastic member 32 is disposed between the blocking member 31 and the cover 12, and the elastic member 32 abuts against the blocking member 31. When the filter member 20 is separated from the cover 12, the elastic member 32 causes the blocking member 31 to protrude from the outer edge of the cover 12. When the filter member 20 is installed on the cover 12, the filter member 20 abuts against the blocking member 31, and the external force applied by the filter member 20 to the blocking member 31 overcomes the external force applied by the elastic member 32 to the blocking member 31, so that the blocking member 31 is retracted to the inner side of the cover 12.

[0047] Specifically, since the blocking member 31 is movably disposed on the cover 12, when the blocking member 31 is not subjected to the force of the filter member 20, the elastic member 32 applies an external force to the blocking member 31, causing the blocking member 31 to protrude beyond the outer edge of the cover 12. At this time, the anti-leakage assembly 30 is in the third position, and the cover 12 cannot be closed on the pouring opening 111, so as to indicate that the filter member 20 is not installed. When the filter member 20 is installed on the cover 12, the filter member 20 abuts against the blocking member 31, thereby applying an external force to the blocking member 31 and overcoming the external force applied to the blocking member 31 by the elastic member 32, so that the blocking member 31 moves and retracts to the inside of the cover 12. At this time, the anti-leakage assembly 30 is in the fourth position, and the cover 12 can be closed on the pouring opening 111.

[0048] In some embodiments, the blocking member 31 includes a push rod 311 rotatably disposed on the cover 12. The push rod 311 has a first end and a second end extending in opposite directions. The second end of the push rod 311 is located inside the cover 12, and the rotation center of the push rod 311 is located between the first end and the second end. The first end of the push rod 311 abuts against the elastic member 32. When the filter member 20 is installed on the cover 12, the filter member 20 abuts against the second end of the push rod 311, causing the first end of the push rod 311 to rotate and retract inside the cover 12. When the filter member 20 is separated from the cover 12, the first end of the push rod 311 is subjected to the elastic force applied by the elastic member 32, causing the first end of the push rod 311 to rotate and protrude beyond the outer edge of the cover 12.

[0049] Specifically, the cover 12 is provided with a protruding post 124, and the push rod 311 is provided with a clearance hole. The protruding post 124 passes through the clearance hole, and the push rod 311 can rotate around the protruding post 124. When the filter component 20 is not installed on the cover 12, the second end of the push rod 311 is not in contact with the filter component 20. The elastic element 32 applies an external force to the first end of the push rod 311, thereby causing the first end of the push rod 311 to rotate to a position protruding beyond the outer edge of the cover 12. When the filter component 20 is installed on the cover 12, the filter component 20 abuts against the second end of the push rod 311, applies a force to the second end of the push rod 311, and at the same time, the push rod 311 rotates, causing the first end of the push rod 311 to overcome the external force applied to the first end of the push rod 311 by the elastic element 32, thereby causing the first end of the push rod 311 to rotate around the protruding post 124 and close to the inside of the cover 12. In some embodiments, the anti-leakage assembly 30 being in the third position means that the first end of the push rod 311 protrudes from the outer edge of the cover 12, and the anti-leakage assembly 30 being in the fourth position means that both the first and second ends of the push rod 311 are retracted into the inner side of the cover 12. Of course, the push rod 311 can also be slidably mounted on the cover 12, thereby allowing the anti-leakage assembly 30 to switch between the third and fourth positions under the action of the filter component 20 and the blocking component 31. Any other modifications within the scope of this application are within the protection scope of this application.

[0050] In some embodiments, the push rod 311 has a bent section 3110, which includes a first section 3111 and a second section 3112. The first section 3111 extends in a direction away from the rotation center of the push rod 311, and the second section 3112 is connected to the first section 3111 and forms a predetermined angle with the first section 3111. The second section 3112 is used to abut against the filter component 20.

[0051] Specifically, the arrangement of the first segment 3111 and the second segment 3112 creates a lever arm structure for the bent segment 3110. This means that when the filter component 20 applies a small external force to the bent segment 3110, the first end of the top rod 311 can overcome the external force applied by the elastic element 32. In some embodiments, the predetermined angle is 90°. In this case, the first segment 3111 and the second segment 3112 are perpendicular, which reduces the space occupied by the bent segment 3110. The perpendicularity between the first segment 3111 and the second segment 3112 ensures that the bent segment 3110 is inside the cover 12 regardless of whether the anti-leakage assembly 30 is in the third or fourth position. In some embodiments, a chamfer is provided at the connection between the first segment 3111 and the second segment 3112. The chamfer is used to disperse the stress at the connection between the first segment 3111 and the second segment 3112, preventing stress concentration at this connection. Of course, in some embodiments the predetermined angle can also be 80°, 85°, 95° and 100°.

[0052] Furthermore, the second segment 3112 has an inclined surface 31121 on the side away from the cover 12, and the distance from the inclined surface 31121 to the cover 12 gradually decreases along the direction of the second segment 3112 away from the first segment 3111.

[0053] It is understandable that when the filter element 20 is installed on the cover 12, the second segment 3112 will come into contact with the filter element 20. In this embodiment, due to the design of the inclined surface 31121, the filter element 20 contacts the inclined surface 31121 during the installation of the filter element 20, reducing the friction between the second segment 3112 and the filter element 20. On the other hand, the inclined direction of the inclined surface 31121 is as shown in the attached figure. Figure 11 The X3 direction provides a guiding function to the inclined surface 31121 during the installation of the filter component 20, making it easier for the filter component 20 to push open the second section 3112. In other words, the filter component 20 is installed from the side away from the cover 12, and the filter component 31 moves along the inclined direction of the inclined surface 31121 and is finally installed into the cover 12.

[0054] Since the first segment 3111 and the second segment 3112 form a lever arm structure, in order to prevent the first segment 3111 and the second segment 3112 from being easily damaged, a reinforcing rib is provided between the first segment 3111 and the second segment 3112 in this embodiment, thereby improving the structural strength of the first segment 3111 and the second segment 3112.

[0055] Furthermore, the elastic element 32 includes a torsion spring 321, with its first end abutting against the cover 12 and its second end abutting against the blocking element 31. That is, when the filter element 20 is not installed on the cover 12, the second end of the push rod 311 is not subjected to external force, and the push rod 311 will not rotate. The torsion spring 321 is in its natural state, allowing the first end of the push rod 311 to protrude beyond the outer edge of the cover 12. When the filter element 20 is installed on the cover 12, the second end of the push rod 311 is subjected to the external force of the filter element 20, causing the push rod 311 to rotate. At this time, the first end of the push rod 311 retracts to the inside of the cover 12, and the torsion spring 321 is compressed.

[0056] It is known that when the push rod 311 is in the third position, it can rotate to the fourth position along the first rotation direction, and when the push rod 311 is in the fourth position, it can rotate to the third position along the second rotation direction. To prevent excessive external force on the push rod 311, which could cause it to continue rotating after reaching the third or fourth position and thus fail to stop at the third or fourth position, thereby failing to remind the user that the filter component 20 is missing, in this embodiment, the cover 12 is also provided with multiple stop portions 33 at intervals. The blocking member 31 is at least partially movably disposed between two stop portions 33. When the blocking member 31 protrudes from the outer edge of the cover 12, it abuts against one of the stop portions 33; when the blocking member 31 is retracted to the inner side of the cover 12, it abuts against the other stop portion 33.

[0057] In other words, when the push rod 311 reaches the third position under the action of an external force, it stops at the third position due to the action of the stop part 33. Similarly, when the push rod 311 reaches the fourth position under the action of an external force, it stops at the fourth position due to the action of the stop part 33. In this embodiment, the stop part 33 includes a stop protrusion.

[0058] In some existing dustbins, the filter element 20 is installed on the box body 11. When it is necessary to empty the garbage and dirt inside the box body 11, the cover 12 must first be opened to open the pouring port 111, and then the filter element 20 must be removed from the box body 11 before the garbage and dirt inside the box body 11 can be emptied to prevent the garbage or dirt from contaminating the filter element 20. This arrangement means that the filter element 20 must be removed every time the garbage and dirt inside the box body 11 needs to be emptied, which is inconvenient for users. To solve the above problem, in this embodiment, the cover 12 has a mounting groove 121 on the side near the box body 11, and the filter element 20 is detachably installed in the mounting groove 121. That is to say, after the cover 12 is opened to open the pouring port 111, the filter element 20 is located outside the box body 11, and the garbage and dirt inside the box body 11 will not be contaminated when emptying. In some embodiments, the inlet 112 is formed on the housing 11, and the suction port 123 is formed on the cover 12 and communicates with the mounting groove 121. Additionally, it is understood that when the filter element 20 is installed in the mounting groove 121, the push rod 311 abuts against the filter element 20, applying a certain external force to the filter element 20 to improve its stability within the mounting groove 121.

[0059] Furthermore, a first connecting portion 122 is provided within the mounting groove 121, and a second connecting portion 21 adapted to the first connecting portion 122 is provided on the filter component 20. The first connecting portion 122 and the second connecting portion 21 cooperate to allow the filter component 20 to be installed in the mounting groove 121. Specifically, when the first connecting portion 122 and the second connecting portion 21 cooperate, the filter component 20 is installed in the mounting groove 121, and when the first connecting portion 122 and the second connecting portion 21 are separated, the filter component 20 is separated from the mounting groove 121.

[0060] In some embodiments, one of the first connecting portion 122 and the second connecting portion 21 includes a connecting rib 1221, and the other includes a connecting groove 211. The connecting rib 1221 and the connecting groove 211 are simple in design and can reduce the manufacturing cost of the dust box to a certain extent. Of course, one of the first connecting portion 122 and the second connecting portion 21 can also be a bolt, and the other can also be a nut that mates with the bolt. One of the first connecting portion 122 and the second connecting portion 21 can also be a first magnetic element, and the other can also be a second magnetic element. Any other modifications within the scope of this application are within the protection scope of this application.

[0061] In some embodiments, the connecting ribs 1221 include a plurality of connecting ribs 1221, which are spaced apart on the inner sidewall of the mounting groove 121. The connecting grooves 211 include a plurality of connecting grooves 211, which are spaced apart on the outer sidewall of the filter component 20. Each connecting groove 211 corresponds one-to-one with each connecting rib 1221.

[0062] This design makes the filter component 20 more stable when installed in the mounting groove 121. In one specific embodiment, the mounting groove 121 includes a rectangular groove, the filter component 20 has a rectangular structure, a connecting rib 1221 is provided on each of the four inner side walls of the rectangular groove, and a connecting groove 211 is provided on each of the four outer side walls of the filter component 20, thereby improving the stability of the filter component 20 installed in the mounting groove 121.

[0063] In some embodiments, the connecting rib 1221 protrudes from the inner wall of the mounting groove 121. The side of the connecting rib 1221 facing away from the bottom surface of the mounting groove 121 has a first guide surface 12211. Along the protrusion direction of the connecting rib 1221, the distance from the first guide surface 12211 to the bottom surface of the mounting groove 121 gradually decreases.

[0064] As attached Figure 7As shown, when actually installing the filter component 20 onto the cover 12, the filter component 20 is first placed on top of the mounting groove 121, and then an external force is applied to the filter component 20 along the depth direction of the mounting groove 121, so that the connecting rib 1221 in the mounting groove 121 is engaged in the connecting groove 211 of the filter component 20. To avoid significant friction between the connecting rib 1221 and the connecting groove 211 during the engagement process, which could damage the connecting rib 1221 or the connecting groove 211, this embodiment provides a first guide surface 12211. Since the distance from the first guide surface 12211 to the bottom surface of the mounting groove 121 gradually decreases along the protrusion direction of the connecting rib 1221, this means that the first guide surface 12211 is an inclined surface, and the inclination direction of the inclined surface is as shown in the attached figure. Figure 8 In the X1 direction, the first guide surface 12211 is set so that when the connecting rib 1221 and the connecting groove 211 are engaged, the pressure between the two can be distributed to the first guide surface 12211, so that the friction between the two is not too large, thus making it easy for the connecting rib 1221 to pass through the connecting groove 211.

[0065] In practice, when disassembling the filter component 20 from the cover 12, a pry bar or other lifting mechanism is required because the connecting rib 1221 engages with the connecting groove 211, making the disassembly of the filter component 20 overly cumbersome. Therefore, in this embodiment, the connecting rib 1221 protrudes from the inner wall of the mounting groove 121, and the side of the connecting rib 1221 near the bottom surface of the mounting groove 121 has a second guide surface 12212. Along the protrusion direction of the connecting rib 1221, the distance from the second guide surface 12212 to the bottom surface of the mounting groove 121 gradually increases. Similarly, since the distance from the second guide surface 12212 to the bottom surface of the mounting groove 121 gradually increases along the protrusion direction of the connecting rib 1221, the second guide surface 12212 is also an inclined surface, and the inclination direction of the second guide surface 12212 is as shown in the attached figure. Figure 8 In the X2 direction, when the filter component 20 is subjected to an external force along the depth direction away from the mounting groove 121, that is, when the filter component 20 is separated from the mounting groove 121 by the external force, thanks to the design of the second guide surface 12212, interference between the connecting rib 1221 and the connecting groove 211 is avoided, so that the connecting rib 1221 can be separated from the connecting groove 211 without using the lifting component.

[0066] Furthermore, the first end of the cover 12 is rotatably connected to the box body 11, and the cover 12 can rotate between a first position and a second position. Specifically, the first end of the cover 12 is hinged to the box body 11, and the second end of the cover 12 can rotate around the first end of the cover 12, thereby allowing the cover 12 to switch between the first position and the second position. In some embodiments, the second end of the cover 12 is provided with a buckle, and the box body 11 is provided with a slot that matches the buckle. When the buckle engages with the slot, the cover 12 covers the pouring opening 111.

[0067] In summary, the dust box of this application, by setting an anti-leakage component 30, is in the third position when the filter component 20 is not installed on the cover 12, preventing the cover 12 from closing onto the pouring opening 111, thus reminding the user that the filter component 20 is not installed in the dust box. When the filter component 20 is installed on the cover 12, the anti-leakage component 30 is in the fourth position, allowing the cover 12 to close onto the pouring opening 111. Furthermore, the anti-leakage assembly 30 includes a blocking member 31 and an elastic member 32. The blocking member 31 includes a push rod 311, and the elastic member 32 includes a torsion spring 321. The first end of the torsion spring 321 abuts against the cover 12, and the second end of the torsion spring 321 abuts against the first end of the push rod 311. When the filter component 20 is installed on the cover 12, the second end of the push rod 311 abuts against the filter component 20, thereby causing the push rod 311 to retract inside the cover 12. When the filter component 20 is not installed on the cover 12, the first end of the push rod 311 protrudes from the outer edge of the cover 12 under the action of the torsion spring 321, thereby reminding the user that the filter component 20 is not installed. In addition, unlike the prior art, the filter component 20 of this application is detachably installed in the mounting groove 121, so that the filter component 20 does not need to be disassembled when it is necessary to empty the garbage in the box 11. On the other hand, the filter component 20 is installed in the mounting groove 121 through the cooperation of the connecting rib 1221 and the connecting groove 211, which reduces the manufacturing cost of the dust box. In addition, the connecting rib 1221 is provided with a first guide surface 12211 and a second guide surface 12212, which facilitates the installation and removal of the filter component 20.

[0068] 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.

[0069] 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 application.

[0070] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
