Description

Technical Field

[0001] This utility model relates to cleaning tools, and more particularly to a broom head and a broom. Background Technology

[0002] While existing brooms can effectively remove larger debris when sweeping the floor, they are not effective at cleaning up dust. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a broom head that can not only clean up large debris but also remove dust.

[0004] In a first aspect, this utility model provides a broom head, including a first working head.

[0005] The first working head includes a first cleaning head and a liquid dispensing device; the first cleaning head is capable of absorbing water and has a first cleaning end for cleaning the ground; the liquid dispensing device is connected to the first cleaning head and includes a switch assembly for controlling the liquid dispensing device to switch between a liquid dispensing state and a closed state.

[0006] The switching assembly has an operating end near the first cleaning end. When the operating end is in contact with the ground, the switching assembly is turned on, putting the liquid dispensing device in a liquid dispensing state to provide liquid to the first cleaning head or the ground. When the operating end is separated from the ground, the switching assembly is turned off, putting the liquid dispensing device in a closed state.

[0007] With the above technical solution, the broom head provided by this utility model includes a first working head, which includes a first cleaning head, and can clean up large debris on the ground through the first cleaning end of the first cleaning head.

[0008] When dust needs to be cleaned, the first working head also includes a liquid dispensing device, which can provide liquid to the first cleaning head or the ground. Since the first cleaning head can absorb water, it becomes wet when it comes into contact with the liquid, which can stick the dust on the ground to the first cleaning head, thereby cleaning the dust.

[0009] In addition, the liquid dispensing device also includes a switch assembly. The switch assembly has an operating end near the first cleaning end. When it is necessary to wet the first cleaning head, the operating end is brought into contact with the ground to open the switch assembly, so that the liquid dispensing state is in the dispensing state. Not only is it convenient to use without having to manually open the switch assembly, but also, by directly contacting the operating end with the ground to control the opening of the switch assembly, it is easy to control the force and precisely control the switch assembly.

[0010] Optionally, the first cleaning head is flexible, and the operating end is located inside the first cleaning head; when the first cleaning head deforms upon contact with the ground, the operating end can contact the ground to open the switch assembly.

[0011] With the above technical solution, the first cleaning head is flexible and the operating end is located inside the first cleaning head. During the sweeping process, the user can control the operating end to contact the ground and turn on the switch component by controlling the deformation of the first cleaning head. No other action is required, making it simpler and more convenient to use.

[0012] In addition, the operating end is located inside the first cleaning head, which protects the operating end.

[0013] Optionally, a gap of 1-3 cm is left between the end of the operating end and the first cleaning end of the first cleaning head.

[0014] With the above technical solution, when liquid dispensing is not required, the user can use the portion of the first cleaning end that extends beyond the operating end to clean the floor normally. Even if the first cleaning end deforms slightly during use, the operating end will not come into contact with the floor. When liquid dispensing is required, the user increases the pressure on the first cleaning head, causing it to deform and the operating end to come into contact with the floor, thus opening the switch assembly. This allows the user to select whether to add liquid as needed, making it more convenient to use.

[0015] Optionally, the liquid outlet of the liquid dispensing device is located at the connection between the first cleaning head and the liquid dispensing device. When the liquid dispensing device is in the liquid dispensing state, the liquid in the liquid dispensing device enters the interior of the first cleaning head through the liquid outlet.

[0016] When the above technical solution is adopted, when the liquid dispensing device is in the liquid dispensing state, the liquid can directly enter the first cleaning head from the liquid outlet, which not only dispenses the liquid quickly, but also prevents it from spilling to other places.

[0017] Optionally, the liquid dispensing device is connected above the first cleaning head, and the liquid outlet is located on the bottom surface of the liquid dispensing device. When the liquid dispensing device is in the liquid dispensing state, the liquid enters the interior of the first cleaning head under the action of gravity.

[0018] With the above technical solution, the liquid enters the interior of the first cleaning head under the action of gravity, which not only achieves rapid liquid discharge, but also eliminates the need for an additional driving device, resulting in a simple and ingenious structure.

[0019] Optionally, the operating end of the switch assembly is rod-shaped.

[0020] With the above technical solution, the operating end can be easily extended to the ground to make contact with the ground. Moreover, the operating end is rod-shaped, which occupies little space and reduces the impact on the first cleaning head.

[0021] Optionally, the switching assembly is a one-way valve, which is movably disposed at the outlet of the liquid outlet device. The end of the one-way valve away from the outlet extends to form the operating end. When the operating end contacts the ground, the operating end drives the one-way valve to open the outlet.

[0022] With the above technical solution, the one-way valve has a simple structure and saves costs.

[0023] Optionally, the broom head further includes a connecting seat and a second working head, the second working head having a second cleaning end for cleaning the floor;

[0024] Along the width direction of the broom head, the first working head and the second working head are arranged side by side on the connecting seat; the broom head also includes a lifting device, through which the first working head can be raised and lowered on the connecting seat to change the distance between the first cleaning end and the ground; or,

[0025] The second working head can be raised and lowered on the connecting seat via the lifting device to change the distance between the second cleaning end and the ground.

[0026] With the above technical solution, the broom head also includes a second working head, and the first working head or the second working head is mounted on the connecting seat via a lifting device. Users can use the first working head or the second working head individually or in combination as needed, making the broom head provided by this utility model more widely applicable.

[0027] Optionally, the lifting device includes a lead screw and nut pair; and / or, the second working head includes a scraper.

[0028] When the above technical solution is adopted, the lifting device includes a lead screw and nut pair, which has a simple structure and is easy to operate;

[0029] In addition, the second working head includes a scraper. Users can use the first cleaning head to sweep the floor as needed, and then use the second working head to wring out water after sweeping.

[0030] You can also use only the first cleaning head to sweep the floor, or only the second working head to squeegee water;

[0031] They can also be used simultaneously. The first cleaning head sweeps the floor in front of the cleaning direction, while the second working head scrapes the floor in the rear of the cleaning direction, achieving wiping first and then scraping to improve cleaning efficiency and effectiveness.

[0032] In addition, the second working head is a scraper, and wetting the scraper will affect the water-scraping effect; while the liquid dispensing device can provide liquid to the first cleaning head without wetting the entire broom head. Therefore, the broom head provided in this embodiment of the present invention can not only provide liquid to the first cleaning head, but also will not affect the water-scraping effect of the scraper.

[0033] Secondly, this utility model also provides a broom. The broom includes the broom head described in the first aspect or any possible implementation of the first aspect.

[0034] The beneficial effects of the broom provided in the second aspect are the same as those of the broom head described in the first aspect or any possible implementation of the first aspect, and will not be repeated here.

[0035] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] The following is for reference. Figure 1-4 As shown, this embodiment of the utility model provides a broom head including a first working head 1.

[0048] like Figure 1 As shown, the first working head 1 includes a first cleaning head 10 and a liquid dispensing device 11. The first cleaning head 10 can absorb water; for example, the material of the first cleaning head 10 is a sponge or PVC foam, which can not only sweep the floor but also absorb water. Of course, the first cleaning head 10 can also be a wiping cloth, which can also sweep the floor or absorb water.

[0049] The first cleaning head 10 has a first cleaning end 100 for cleaning the floor. For example, the end of the first cleaning head 10 closest to the floor is the first cleaning end 100. Figure 1 As shown, the bottom end of the first cleaning head 10 is the first cleaning end 100.

[0050] like Figure 1 and Figure 2 As shown, the liquid dispensing device 11 is connected to the first cleaning head 10, either directly or indirectly. For example, the liquid dispensing device 11 is disposed on the top or side surface of the first cleaning head 10, or the liquid dispensing device 11 is connected to the first cleaning head 10 via a connecting plate. Specifically, the liquid dispensing device 11 has a liquid storage space 110, and a liquid outlet 11 and a water inlet 112 communicating with the liquid storage space 110. Liquid is added to the liquid storage space 110 through the water inlet 112 and dispensed through the liquid outlet 11.

[0051] The liquid dispensing device 11 includes a switching assembly 113, which controls the liquid dispensing device 11 to switch between a liquid dispensing state and a closed state. Specifically, when the liquid dispensing device 11 is in the liquid dispensing state, the liquid outlet 11 is open, and liquid flows out of the liquid storage space 110 from the liquid outlet 11; when the liquid dispensing device 11 is in the closed state, the liquid outlet 11 is closed.

[0052] Switch assembly 113 has an operating end 1130 near the first cleaning end 100, specifically, as Figure 3 As shown, the operating terminal 1130 is the lower end of the switch assembly 113.

[0053] When the operating end 1130 contacts the ground, the switch assembly 113 opens, putting the liquid dispensing device 11 into a liquid dispensing state to supply liquid to the first cleaning head 10 or the ground; when the operating end 1130 separates from the ground, the switch assembly 113 closes, putting the liquid dispensing device 11 into a closed state.

[0054] In practical applications, when cleaning larger debris on the ground, such as fruit peels or paper scraps, the first cleaning end 100 can be used to clean them. In this case, the first cleaning head 10 does not need to be wet. During use, the user should avoid contact between the operating end 1130 of the switch assembly 113 and the ground; or, water should not be added to the liquid dispensing device 11.

[0055] When cleaning dust from the floor, water can be added to the liquid dispensing device 11 beforehand. The operating terminal 1130 of the switch assembly 113 is brought into contact with the floor, opening the switch assembly 113 and putting the liquid dispensing device 11 into a dispensing state. At this time, the liquid dispensing device 11 can supply liquid to the first cleaning head 10, wetting it. The liquid dispensing device 11 can also supply liquid to the floor, wetting the first cleaning head 10 upon contact with the liquid. Cleaning the floor with the wet first cleaning head 10 will cause dust to adhere to it, thus cleaning the dust away.

[0056] With the above technical solution, the broom head provided by this utility model includes a first working head 1, and the first working head 1 includes a first cleaning head 10, which can clean up large debris on the ground through the first cleaning end 100 of the first cleaning head 10.

[0057] When dust needs to be cleaned, the first working head 1 also includes a liquid dispensing device 11, which can provide liquid to the first cleaning head 10 or the ground. Since the first cleaning head 10 can absorb water, it can become wet when it comes into contact with the liquid, which can stick the dust on the ground to the first cleaning head 10, thereby cleaning the dust.

[0058] In addition, the liquid dispensing device 11 also includes a switch assembly 113. The switch assembly 113 has an operating end 1130 near the first cleaning end 100. When it is necessary to make the first cleaning head 10 wet, the operating end 1130 is brought into contact with the ground to open the switch assembly 113, so that the liquid dispensing state is in the liquid dispensing state. Not only is it convenient to use without manually opening the switch assembly 113, but also, by directly contacting the operating end 1130 with the ground to control the opening of the switch assembly 113, it is easy to control the force and precisely control the switch assembly 113.

[0059] In one possible implementation, such as Figure 1 As shown, the first cleaning head 10 can be flexible, for example, the material of the first cleaning head 10 is sponge or PVC foam.

[0060] like Figure 3 As shown, the operating end 1130 is located inside the first cleaning head 10. Specifically, the first cleaning head 10 has a channel, and the end of the channel near the ground has an opening. The operating end 1130 is located inside the first cleaning head 10 and can contact the ground through the opening.

[0061] When the first cleaning head 10 deforms upon contact with the ground, the operating end 1130 can contact the ground, causing the switch assembly 113 to open.

[0062] In practical applications, when dust needs to be cleaned, the user applies more force to sweep the floor through the first cleaning head 10. The reaction force from the ground causes the first cleaning head 10 to deform and contract, allowing the operating end 1130 of the switch assembly 113 to contact the ground through the opening. As the first cleaning head 10 continues to deform and contract, the force from the ground also continuously applies force to the operating end 1130 of the switch assembly 113, causing the switch assembly 113 to open, thereby allowing the liquid dispensing device 11 to supply liquid to the first cleaning head 10 or the ground.

[0063] With the above technical solution, the first cleaning head 10 is flexible and the operating end 1130 is located inside the first cleaning head 10. During the sweeping process, the user can control the operating end 1130 to contact the ground by controlling the deformation of the first cleaning head 10, so that the switch assembly 113 can be turned on without any other action, making it simpler and more convenient to use.

[0064] In addition, the operating end 1130 is located inside the first cleaning head 10, and the first cleaning head 10 can protect the operating end 1130.

[0065] In one example, a gap of 1-3 cm is left between the end of the aforementioned operating end 1130 and the first cleaning end 100 of the first cleaning head 10.

[0066] When the above technical solution is adopted, when liquid is not required, the user can use the part of the first cleaning end 100 that extends beyond the operating end 1130 to clean the ground normally. Even if the first cleaning end 100 is slightly deformed during use, the operating end 1130 will not come into contact with the ground. When liquid is required, the user increases the pressure on the first cleaning head 10, which increases the deformation of the first cleaning head 10, and the operating end 1130 can then come into contact with the ground, causing the switch assembly 113 to open. This allows the user to select whether to add liquid as needed, making it more convenient to use.

[0067] In another possible implementation, the aforementioned operating end 1130 may be located outside the first cleaning head 10, and when the first cleaning head 10 is tilted, the operating end 1130 may contact the ground to open the switch assembly 113.

[0068] Specifically, the operating end 1130 can be tilted downwards and positioned to the left of the first cleaning head 10. When liquid needs to be dispensed, the broom head can be tilted to the left so that the operating end 1130 contacts the ground, thereby opening the switch assembly 113 and wetting the first cleaning head 10. After the liquid dispensing action is completed, the first cleaning head 10 can be used again to clean the ground.

[0069] In one possible implementation, the outlet 11 of the liquid dispensing device 11 may be located at the connection between the first cleaning head 10 and the liquid dispensing device 11. When the liquid dispensing device 11 is in the liquid dispensing state, the liquid in the liquid dispensing device 11 enters the interior of the first cleaning head 10 through the outlet 11.

[0070] When the above technical solution is adopted, when the liquid dispensing device 11 is in the liquid dispensing state, the liquid can directly enter the first cleaning head 10 from the liquid outlet 11, which not only dispenses the liquid quickly, but also prevents it from spilling to other places.

[0071] In one alternative approach, such as Figure 3As shown, the liquid dispensing device 11 can be connected above the first cleaning head 10. The liquid outlet 11 is located on the bottom surface of the liquid dispensing device 11. When the liquid dispensing device 11 is in the liquid dispensing state, the liquid enters the interior of the first cleaning head 10 under the action of gravity.

[0072] With the above technical solution, the liquid enters the interior of the first cleaning head 10 under the action of gravity, which not only achieves rapid liquid discharge, but also eliminates the need for an additional driving device, resulting in a simple and ingenious structure.

[0073] In another alternative, the liquid dispensing device 11 may also be located on the left side of the first cleaning head 10, with the liquid outlet 11 located on the left side of the liquid dispensing device 11 near the bottom. When the liquid dispensing device 11 is in the dispensing state, the liquid enters the interior of the first cleaning head 10 from the left side.

[0074] In another possible implementation, the outlet 11 of the aforementioned liquid dispensing device 11 can also be located on the side of the liquid dispensing device 11. For example, when the liquid dispensing device 11 is connected above the first cleaning head 10, the outlet 11 can be located on the left side of the liquid dispensing device 11. When the switch assembly 113 is turned on, the liquid from the liquid dispensing device 11 flows from the outlet 11 to the ground, providing liquid to the ground. Then, the first cleaning head 10 comes into contact with the liquid on the ground, making the first cleaning head 10 wet.

[0075] In one possible implementation, the operating end 1130 of the aforementioned switch assembly 113 may be rod-shaped.

[0076] Specifically, such as Figure 3 As shown, the operating end 1130 of the switch assembly 113 is a long rod that extends towards the ground to facilitate contact with the ground.

[0077] With the above technical solution, the operating end 1130 can be easily extended to the ground to make contact with the ground. Moreover, the operating end 1130 is rod-shaped, which occupies little space and reduces the impact on the first cleaning head 10.

[0078] In one alternative embodiment, the switch assembly 113 may be a one-way valve, which is movably disposed at the outlet 11 of the liquid outlet device 11. The end of the one-way valve away from the outlet 11 extends to form the operating end 1130. When the operating end 1130 contacts the ground, the operating end 1130 drives the one-way valve to open the outlet 11.

[0079] With the above technical solution, the one-way valve has a simple structure and saves costs.

[0080] Specifically, such as Figure 3As shown, the one-way valve includes a stem 1131, a seal 1132, and a return spring 1133. The seal 1132 is located at one end of the stem 1131 and is situated inside the liquid outlet device 11. The end of the stem 1131 furthest from the seal 1132 forms an operating end 1130. The one-way valve is installed at the liquid outlet 11, and the return spring 1133 applies a force close to the liquid outlet 11 to the seal 1132, thereby enabling the seal 1132 to seal the liquid outlet 11.

[0081] When the operating end 1130 contacts the ground, the operating end 1130 drives the sealing element 1132 to move into the liquid outlet device 11, so that the sealing element 1132 separates from the liquid outlet 11 and opens the liquid outlet 11. At this time, the return spring 1133 is in a compressed state. When the operating end 1130 separates from the ground, the return spring 1133 releases its energy, so that the sealing element 1132 abuts against the liquid outlet 11 and closes the liquid outlet 11.

[0082] In another alternative embodiment, the aforementioned switch assembly 113 can also be an electric switch. The electric switch has a trigger rod on its outer side, with the end of the trigger rod near the ground forming an operating end 1130. When the operating end 1130 contacts the ground, the electric switch receives a force transmitted from the ground, causing it to open and open the outlet 11; when the operating end 1130 separates from the ground, the force on the electric switch disappears, and the electric switch closes, closing the outlet 11.

[0083] In one possible implementation, such as Figure 1-4 As shown, the broom head may further include a connecting seat 12 and a second working head 13. The second working head 13 has a second cleaning end 130 for cleaning the floor.

[0084] Along the width direction of the broom head, the first working head 1 and the second working head 13 are arranged side by side on the connecting seat 12. The length of the broom head is much greater than its width, such as... Figure 4 As shown, the length direction of the broom head is left-right, and the width direction is front-back. The first working head 1 and the second working head 13 are arranged side by side on the connecting seat 12, and the first working head 1 and the second working head 13 have different cleaning effects. The first working head 1 and the second working head 13 work together to improve the cleaning effect on the ground.

[0085] The broom head also includes a lifting device 14, through which the first working head 1 can be raised and lowered on the connecting base 12 to change the distance between the first cleaning end 100 and the ground. Alternatively, the second working head 13 can be raised and lowered on the connecting base 12 through the lifting device 14 to change the distance between the second cleaning end 130 and the ground.

[0086] like Figure 3 and Figure 4As shown, the first working head 1 can be raised and lowered on the connecting seat 12 via the lifting device 14, and the second working head 13 is fixedly mounted on the connecting seat 12. Specifically, the second working head 13 can be fixed on the connecting seat 12 by snap-fit ​​or plug-in method.

[0087] In practical applications, the lifting device 14 can be used to adjust the height of the first working head 1 relative to the connecting seat 12, thereby changing the distance between the first cleaning end 100 and the ground, so that the first cleaning end 100 is higher than, lower than or equal to the second cleaning end 130.

[0088] When the first cleaning end 100 is higher than the second cleaning end 130, the user can use only the second working head 13 to clean the ground.

[0089] When the first cleaning end 100 is lower than the second cleaning end 130, the user can use only the first working head 1 to clean the ground.

[0090] When the first cleaning end 100 is equal to the second cleaning end 130, the user can simultaneously use the first working head 1 and the second working head 13 to clean the floor. For example, if the first working head 1 is located in front of the second working head 13, during cleaning, the first working head 1 cleans the floor first, while the second working head 13 performs supplementary cleaning behind the first working head 1. Alternatively, if the second working head 13 is located in front of the first working head 1, during cleaning, the second working head 13 cleans the floor first, while the first working head 1 performs supplementary cleaning behind the first working head 1.

[0091] The second working head 13 can be raised and lowered on the connecting seat 12 via the lifting device 14, and its working principle is similar to that of the first working head 1, which can be raised and lowered on the connecting seat 12 via the lifting device 14, and will not be described again here.

[0092] In the case of adopting the above technical solution, the broom head also includes a second working head 13, and the first working head 1 or the second working head 13 is mounted on the connecting seat 12 through the lifting device 14. The user can use the first working head 1 or the second working head 13 alone as needed, or use the first working head 1 and the second working head 13 in combination, so that the broom head provided by this utility model has a wider range of applications.

[0093] In one alternative embodiment, the lifting device 14 may include a cylinder, one end of which is connected to the connecting seat 12, and the other end of which is connected to the first working head 1 or the second working head 13. The cylinder extends and retracts to drive the first working head 1 or the second working head to rise and fall relative to the connecting seat 12.

[0094] In another alternative embodiment, the lifting device 14 may include a lead screw and nut assembly, comprising a lead screw 140 and a nut 141. For example... Figure 3 and Figure 4As shown, taking the first working head 1 as an example, the lead screw 140 is vertically mounted on the top of the first working head 1, and the nut 141 is rotatably mounted on the connecting seat 12. The connecting seat 12, located above the nut 141, is provided with a limiting member to restrict the vertical movement of the nut 141 relative to the connecting seat 12. The end of the lead screw 140 away from the first working head 1 passes through the connecting seat 12 and is threadedly connected to the nut 141.

[0095] In practical applications, when it is necessary to raise or lower the first working head 1, the nut 141 is rotated relative to the connecting seat 12. Since the connecting seat 12 restricts the nut 141 from raising or lowering, and the nut 141 is threadedly connected to the lead screw 140, the nut 141 drives the lead screw 140 to raise or lower. During the raising or lowering process, the lead screw 140 realizes the raising or lowering of the first working head 1.

[0096] When the above technical solution is adopted, the lifting device 14 includes a lead screw and nut pair, which has a simple structure and is easy to operate.

[0097] In one alternative, the second working head 13 may include a scraper.

[0098] like Figure 3 and Figure 4 As shown, the first working head 1 is vertically mounted on the connecting seat 12 via the lifting device 14, and the scraper is fixedly mounted on the connecting seat 12. Specifically, the scraper can be fixed to the connecting seat 12 by snap-fit ​​or plug-in methods.

[0099] In practical applications, the lifting device 14 can be used to adjust the height of the first working head 1 relative to the connecting seat 12, thereby changing the distance between the first cleaning end 100 and the ground, so that the first cleaning end 100 is higher than, lower than or equal to, the second cleaning end 130 of the scraper.

[0100] When the first cleaning end 100 is higher than the second cleaning end 130, the user can clean the floor using only the squeegee.

[0101] When the first cleaning end 100 is lower than the second cleaning end 130, the user can use only the first working head 1 to clean the ground.

[0102] When the first cleaning end 100 is equal to the second cleaning end 130, the user can simultaneously use the first working head 1 and the squeegee to clean the floor. For example, when the first working head 1 is located in front of the squeegee, the first working head 1 cleans the floor first, while the squeegee scrapes water from behind the first working head 1. When the first working head 1 is a sponge and the liquid dispensing device 11 dispenses liquid from the sponge, the first working head 1 can wipe the floor first, and then the squeegee can scrape the water off the floor, achieving cleaning by wiping first and then scraping.

[0103] When the above technical solution is adopted, the second working head 13 is a scraper, and wetting the scraper will affect the water scraping effect; while the liquid dispensing device 11 can provide liquid to the first cleaning head 10 without wetting the entire broom head. Therefore, the broom head provided by this utility model embodiment can not only provide liquid to the first cleaning head 10, but also will not affect the water scraping effect of the scraper.

[0104] This utility model embodiment also provides a broom, including the broom head described above. For example... Figure 5 As shown, the broom includes a broom handle, which is connected to a first working head 1; when the broom head includes a second working head 13, the broom handle is connected to the second working head 13 or the connecting seat 12.

[0105] The beneficial effects of the broom provided in the second aspect are the same as those described in the broom head or any possible implementation of the broom head above, and will not be repeated here. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., 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 utility model. In this specification, 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.

[0106] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
