Description

Technical Field

[0001] This application relates to the field of clean technology, and more specifically, to a steam distribution component and a cleaning device. Background Technology

[0002] Currently, cleaning equipment such as robotic vacuum cleaners and floor scrubbers can efficiently clean surfaces (such as floors and countertops). However, they struggle to remove stubborn stains. To address this, cleaning equipment can use steam to spray hot steam onto the stubborn stains, softening, melting, or loosening them for easier cleaning with the mop. However, the steam spray from these equipment is not ideal for removing stubborn stains, resulting in incomplete cleaning and a poor user experience. Utility Model Content

[0003] The main objective of this application is to provide a steam distribution component and a cleaning device to solve the problem that the steam sprayed by the cleaning devices in the prior art is not very effective in treating stubborn stains and that stubborn stains are not cleaned thoroughly enough.

The size of L1 is not less than 1.4mm and not more than 2mm, and the size of L2 is not less than 3mm and not more than 4mm.

[0015] Furthermore, the connecting member is disposed at one end of the housing along the first direction, the channel includes a steam inlet channel and at least one steam outlet channel, along the third direction, the steam outlet channel is located on one side of the steam inlet channel, one end of the steam inlet channel is connected to the connecting member, and the other end of the steam inlet channel away from the connecting member is provided with a connecting port between it and the steam outlet channel, the connecting port is located in the middle of the steam outlet channel and is connected to the steam outlet channel, the plurality of nozzles are located at the bottom of the steam outlet channel and are connected to the steam outlet channel, and the second cross section is the cross section of the steam outlet channel.

[0016] Furthermore, a partition structure is provided within the channel. Along a third direction, the partition structure is disposed within the steam outlet channel and divides the steam outlet channel into a first channel segment and a second channel segment. The partition structure is disposed opposite to the connecting port and has a first gap between the two opposite sides of the connecting port along the first direction. The first channel segment and the second channel segment are respectively connected to the steam inlet channel through the first gap.

[0017] Furthermore, the partition structure includes:

[0018] The protrusion, along a third direction, is protruding from the inner wall surface of the steam outlet channel on the side away from the steam inlet channel. Along the first direction, the projected outer contours of the side walls on both sides of the protrusion along the second direction are both arc-shaped.

[0019] Furthermore, the steam outlet channel includes two channels, which are located on opposite sides of the steam inlet channel along a third direction, and each of the two steam outlet channels is provided with a connecting port between it and the steam inlet channel.

[0020] Furthermore, along the second direction, a first groove is provided between the bottom surface of the channel and the nozzle, the first groove connecting the channel and the nozzle, and along the second direction, the first groove has a third cross-section, the third cross-section gradually decreasing in the direction closer to the nozzle.

[0021] Furthermore, the axis of the nozzle is parallel to the second direction; and / or,

[0022] Along a third direction, the housing includes a first side and a second side disposed opposite to each other, and the axis of the nozzle is inclined toward the direction closer to the second side.

[0023] Furthermore, the angle between the axis of the nozzle and the second direction is not less than 10° and not greater than 30°.

[0024] Furthermore, it also includes:

[0025] A flow guide column is provided along the second direction, protruding from the bottom surface of the housing. A second groove is provided inside the flow guide column. A protrusion is provided near the bottom of the groove of the housing. A third groove is provided near the bottom of the housing and communicates with the nozzle. Along the second direction, the depth of the second groove is greater than the height of the protrusion.

[0026] On the other hand, this application also provides a cleaning device, the cleaning device including a steam mechanism, the steam mechanism including the steam distribution component and a steam supply component, the steam supply component including a steam generator and a water supply component, the steam generator being connected between the connecting member of the steam distribution component and the water supply component.

[0027] The steam distribution component in this application includes a housing and a connecting member. A channel within the housing extends along a first direction, i.e., the length direction of the channel. Multiple nozzles are also provided within the housing. Along a second direction (i.e., the height direction of the housing), the multiple nozzles are located at the bottom of the housing and communicate with the channel, and are arranged along the first direction. The connecting member is disposed on the housing and communicates with the channel. When the steam distribution component is installed in a cleaning device, steam generated by the steam supply component installed in the cleaning device will be introduced into the channel through the connecting member, and then sprayed onto the surface to be cleaned through the multiple nozzles communicating with the channel. The area S1 of the first cross-section of the nozzle and the area S2 of the second cross-section of the channel satisfy the following relationship: The area ratio of the steam is specified as not less than 2.45% and not more than 42.05%. Within this range, a larger area ratio results in a larger first cross-sectional area, meaning a larger nozzle. When the amount of steam entering the channel is constant, the amount of steam ejected from each nozzle within the same time frame will be greater, allowing more steam to reach stubborn stains. This ensures the speed and force of the steam jet onto the stubborn stains, improving the softening, melting, and loosening effects and efficiency. This allows stubborn stains to be transformed into easily cleanable ordinary stains in a short time, making it easier for cleaning equipment to remove them and preventing stain residue. Secondly, the area ratio should not exceed 42.05%. Therefore, an area ratio within this range prevents the nozzle 102 from becoming too large. With a constant amount of steam in the channel 101, this ensures that the steam is ejected from the nozzle 102 at a higher speed and pressure, rather than diffused. The ejected steam can apply greater steam pressure to stubborn stains and ensure that the stubborn stains can come into contact with more steam, thereby better promoting the softening / melting and loosening of stubborn stains.

Detailed Implementation

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0045] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. 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.

[0046] Existing cleaning equipment (00) does not effectively remove stubborn stains with its steam, leaving them inadequately clean. Through in-depth research, the inventors of this invention have discovered that this is primarily due to the insufficient amount and speed of steam sprayed onto stubborn stains by existing equipment. This results in the stains not receiving enough steam to soften and loosen completely. For example, the limited nozzle diameter restricts steam flow, causing some to condense into water droplets upon cooling, further reducing the amount of pure steam emitted. Additionally, the small nozzle diameter can lead to scale buildup over time, potentially clogging the nozzle and preventing steam from being emitted.

[0047] To address the aforementioned problems, the first embodiment of this utility model provides a steam distribution component 10, please refer to [link to relevant documentation]. Figures 1 to 9 The steam distribution component 10 includes a housing 11 and a connecting member 12. A channel 101 and a nozzle 102 are provided within the housing 11. The channel 101 extends along a first direction, which is the direction of the length of the housing 11. Figure 1 (In the direction indicated by the middle arrow X), the length of the housing 11 is adapted to the roller component 31 of the cleaning device 00. The roller component 31 is used for wet cleaning of the surface to be cleaned (such as the floor, tabletop, etc.). Along the forward direction of the cleaning device 00 (the forward direction is the width direction of the housing 11), the roller component 31 is installed on the rear side of the steam distribution member 10. Thus, after the steam distribution member 10 is connected to the steam supply component 20 installed in the cleaning device 00, the steam generated by the steam supply component 20 is sprayed through the steam distribution member 10 onto the stubborn stains on the surface to be cleaned, so that the stubborn stains are softened / melted, loosened, etc. under the action of the steam, and thus become ordinary stains that are easy to clean. The cleaning device 00 continues to move forward, and the roller component 31 passes over the softened and loosened ordinary stains to easily clean them.

[0048] Multiple nozzles 102 are included. Along the second direction, the multiple nozzles 102 are located at the bottom of the housing 11 and are respectively connected to the channel 101, and the multiple nozzles 102 are arranged along the first direction. The second direction is... Figure 1 The direction indicated by the middle arrow Y is the height direction of the housing 11. A connecting member 12 is disposed on the housing 11 and communicates with the channel 101. The connecting member 12 is adapted to communicate with the steam outlet of the steam supply assembly 20 (specifically with the outlet of the steam generator 21), thereby introducing steam into the channel 101. The steam flowing in the channel 101 is sprayed onto stubborn stains through a plurality of nozzles 102.

[0049] To prevent stubborn stains from not softening sufficiently due to insufficient steam contact, some stains may stubbornly adhere to the surface to be cleaned. The nozzle 102 has a first cross-section along its width direction (i.e., the width direction of the housing 11, referred to below as the third direction; if the nozzle 102 is a circular hole, the width direction is the radial direction of the circular hole), with an area of ​​S1. Along a second direction, the channel 101 has a second cross-section with an area of ​​S2. S1 and S2 satisfy the following relationship:

[0050]

[0051] If limited The area ratio P is defined as follows: P is not less than 2.45% and not greater than 42.05%. Within this range, when the amount of steam entering the channel 101 is constant (i.e., the area S2 of the second cross-section of the channel 101 remains unchanged), the larger the first cross-sectional area of ​​the nozzle 102 is within the same time period, the more steam will be sprayed onto the surface to be cleaned. This means more stubborn stains will come into contact with the steam, thus softening and dissolving them with sufficient steam. This prevents stubborn stains from being partially or completely softened, ensuring that the roller component 31 can easily and efficiently clean stubborn stains. Secondly, because the first cross-sectional area is larger, the diameter of the nozzle 102 will not be too small, ensuring that the steam can be accelerated out of the nozzle 102. This prevents some steam from turning into water droplets due to insufficient flow rate, ensuring that the amount of steam sprayed is as expected and sufficient. Furthermore, because the diameter of the nozzle 102 is not too small, scale is less likely to clog the nozzle 102 when it forms or between the nozzle 102 and the channel 101, ensuring continuous steam output. Regular cleaning of the scale is sufficient during use. Since the area ratio P is no greater than 42.05%, this range prevents the nozzle 102 from becoming too large. With a constant amount of steam in the channel 101, this ensures that the steam is ejected from the nozzle 102 at a higher speed and pressure, rather than diffused. The ejected steam applies greater steam pressure to stubborn stains and ensures that more steam comes into contact with them, thus better promoting softening / melting and loosening.

[0052] As can be seen, the steam distribution component 10 in this embodiment includes a housing 11 and a connecting member 12. A channel 101 is provided inside the housing 11, extending along a first direction, which is the length direction of the channel 101. A plurality of nozzles 102 are also provided inside the housing 11. Along a second direction (the height direction of the housing 11), the plurality of nozzles 102 are located at the bottom of the housing 11 and communicate with the channel 101 respectively, and the plurality of nozzles 102 are arranged along the first direction. The connecting member 12 is disposed on the housing 11 and communicates with the channel 101. When the steam distribution component 10 is installed in the cleaning equipment 00, the steam generated by the steam supply component 20 installed in the cleaning equipment 00 will be introduced into the channel 101 through the connecting member 12, and then sprayed onto the surface to be cleaned through the plurality of nozzles 102 communicating with the channel 101. The area S1 of the first cross-section of the nozzle 102 and the area S2 of the second cross-section of the channel 101 satisfy the following relationship: The area ratio of the steam is specified as follows: the area ratio of the steam distribution component 10 is not less than 2.45% and not more than 42.05%. Within this range, the larger the area ratio, the larger the area of ​​the first cross-section, i.e., the larger the nozzle 102. When the amount of steam entering the channel 101 is constant, the amount of steam ejected from each nozzle 102 will be greater in the same amount of time, and more stubborn stains will come into contact with the steam. This ensures the speed and force of the steam jet onto the stubborn stains, improving the softening, melting, and loosening effects and efficiency of the stubborn stains. This allows the stubborn stains to be transformed into easily cleanable ordinary stains in a short time, enabling the cleaning equipment 00 to more easily clean the stubborn stains and avoid stain residue. Secondly, the area ratio is not greater than 42.05%. Therefore, an area ratio within the above range prevents the nozzle 102 from being too large. When the amount of steam in the channel 101 is constant, it ensures that the steam is ejected from the nozzle 102 at a higher speed and pressure, rather than diffused. The ejected steam can apply greater steam pressure to stubborn stains and ensure that the stubborn stains can come into contact with more steam, thereby better promoting the softening / melting and loosening of stubborn stains.

[0053] In this embodiment, the area ratio P may include 2.45%, 2.58%, 2.8%, 3%, 3.5%, 4%, 4.2%, 4.6%, 5%, 5.4%, 5.8%, 6%, 6.3%, 6.7%, 7%, 7.5%, 8%, 9%, 10%, 12%, 13%, 13.4%, 14.13%, 14.2%, 14.25%, 14.31%, and 14.3%. One of the following: 6%, 14.4%, 14.52%, 15%, 16%, 18%, 20%, 21%, 23%, 25%, 27%, 28%, 29%, 30%, 31%, 34%, 34.5%, 35%, 37%, 38%, 38.8%, 40%, 41%, 42%, 42.05%, or other percentages not less than 2.45% and not greater than 42.05%.

[0054] In this embodiment, S1 and S2 also satisfy the following relationship:

[0055]

[0056] In other words, the area ratio P is not less than 4.81% and not greater than 15.14%. Therefore, having the area ratio P within this range allows the orifice diameter of nozzle 102 to be within a more suitable size range. With a constant amount of steam in channel 101, this ensures that steam is ejected from nozzle 102 at a higher speed and pressure, resulting in a larger steam volume, a longer steam jet range, and steam pressure. This effectively washes away stubborn stains on the ground, accelerating their softening and loosening, and prevents the steam volume ejected from nozzle 102 from decreasing due to some steam condensing into water droplets. The ejected steam can apply greater steam pressure to stubborn stains and ensure that the stains come into contact with more steam, thus better promoting the softening / melting and loosening of stubborn stains. The diffused steam not only doesn't apply enough steam pressure to stubborn stains, but also diffuses more steam away from the stubborn stains, resulting in insufficient steam contact with the stubborn stains. Ultimately, this leads to poor softening and loosening of the stubborn stains, making them difficult to clean later.

[0057] In this embodiment, the area ratio P may include one of the following: 4.81%, 5%, 6.28%, 9%, 9.7%, 10%, 11.96%, 14.2%, 14.25%, 14.31%, 14.36%, 14.4%, 14.52%, 15%, 15.14%, or any other percentage value between 4.81% and 15.14%.

[0058] This embodiment is in When the value is not less than 2.45% and not greater than 42.05%, a steam flow rate of 6 g / min (in grams per minute) is introduced into channel 101 to measure the amount of steam ejected from nozzle 102.

[0059] 11) When the area ratio P is less than 2.45%, such as when the diameter of nozzle 102 is less than 0.5mm (can be 0.45mm), the steam quantity measurement data includes: ①5.03g; ②5.05g; ③5.06g. Disadvantages: (1) Due to the small diameter, the steam outflow is slowed down, causing some steam to turn into water droplets when it cools down. Water droplets can be clearly seen falling near nozzle 102, resulting in less pure steam being sprayed out; (2) If the diameter is too small, scale will form after long-term use, which may clog the nozzle, resulting in the inability to spray steam and also reducing the amount of steam obtained.

[0060] 12) When the area ratio is 9.7%, such as when the diameter of nozzle 102 is 0.8mm, the steam quantity measurement data include: ①5.85g; ②5.86g; ③5.83g.

[0061] When the relative area ratio is less than 2.45%, the amount of steam ejected increases significantly. The steam ejection range is long and the steam has steam pressure, which can wash away stubborn stains on the ground to accelerate the softening and loosening of stubborn stains.

[0062] 13) When the area ratio is greater than 42.05%, that is, the diameter of the nozzle 102 is greater than 1.5mm (e.g., 1.52mm), the steam quantity measurement data includes: ① 5.29g; ② 5.32g; ③ 5.34g. At this time, the diameter of the nozzle 102 is too large, and the steam flows out rapidly. A large amount of steam flows out at the same time, causing some of the steam to turn into water droplets when it encounters cold. Water droplets can be clearly seen falling to the ground near the nozzle 102 of the steam distribution component 10, resulting in less pure steam being sprayed out. Secondly, because the diameter of the nozzle 102 is too large, the steam pressure is low, resulting in poor spraying effect at the steam flow nozzle, which leads to diffusion. As a result, the steam cannot be sprayed to the ground and condenses into water droplets, resulting in poor steam cleaning effect.

[0063] The measurement results above show that when the amount of steam introduced into channel 101 is constant, and the area ratio P is less than 2.45% and greater than 42.05%, the amount of steam ejected from nozzle 102 is relatively small, which is not conducive to the removal of stubborn stains. When the area ratio P is 9.7%, the amount of steam ejected from nozzle 102 is larger, which generates a larger jet pressure and achieves the effect of rinsing away stubborn stains.

[0064] The area S1 of the first cross-section of the nozzle 102 is not less than 0.196 mm. 2 and not greater than 1.766mm 2 (Unit: square millimeters). This ensures that the steam flow is not slowed down or easily clogged by scale due to an excessively small nozzle 102, nor is the steam injection effect affected or the amount of steam reduced due to an excessively large nozzle 102. In other words, when the size of the nozzle 102, S1, is within the above range, it ensures a large amount of steam injected, a fast steam injection speed, and that it is not easily clogged by scale. The size of S1 can include 0.196 mm. 2 0.2mm 2 0.3mm 2 0.4mm 2 0.5mm 2 0.6mm 2 0.7mm 2 0.8mm 2 0.9mm 2 1.0mm 2 1.1304mm 2 1.14mm 2 1.23mm 2 1.51mm 2 1.6mm 21.7mm 2 1.766mm 2 One of them, or 0.196mm 2 Up to 1.766mm 2 Any other value between these two values. In this case, the nozzle 102 in this embodiment may include at least one of the following: rectangular nozzle, polygonal nozzle, rhomboid nozzle, elliptical nozzle, circular nozzle, etc.

[0065] The area S2 of the second cross-section of channel 101 is not less than 4.2 mm. 2 and no larger than 8mm 2 When the area S2 is within this range, the area S2 is not less than 4.2 mm. 2 This ensures that the amount of steam entering channel 101 is sufficient so that nozzle 102 can spray enough steam onto stubborn stains. Importantly, the size of S2 is not less than 4.2 mm. 2 and no larger than 8mm 2 At the same steam volume, this ensures a relatively high steam pressure entering channel 101. Under this higher steam pressure, the steam ejected from nozzle 102 can apply greater steam pressure to stubborn stains, thereby improving the softening and loosening effect of the steam on the stubborn stains. Area S2 is not greater than 8mm². 2 This also avoids the risks of deformation, rupture, and steam leakage in the pipes and nozzles 102 due to excessive steam accumulation in the channel 101. The area S2 can be 4.2 mm. 2 4.3mm 2 4.4mm 2 4.5mm 2 4.7mm 2 4.8mm 2 5mm 2 5.1mm 2 5.2mm 2 5.3mm 2 5.4mm 2 5.6mm 2 5.8mm 2 6mm 2 6.1mm 2 6.2mm 2 6.4mm 2 6.5mm 2 6.8mm 2 6.9mm 2 7mm 2 7.1mm 2 7.2mm 2 7.4mm 2 7.5mm 27.7mm 2 7.8mm 2 8mm 2 One of them, or 4.2mm. 2 Up to 8mm 2 Any other value between these two values.

[0066] In one embodiment, the first cross-section is circular (e.g., Figure 5 As shown in the diagram, the nozzle 102 is a circular orifice. A circular nozzle 102 provides less resistance to steam flow, reducing energy loss and improving injection efficiency. When the nozzle 102 is circular, the diameter of its first cross-section (i.e.,...) Figure 3 and Figure 5 As shown, D) is not less than 0.5 mm and not greater than 1.5 mm. When the size of S1 of the nozzle 102 is within the above range, it can ensure that the amount of steam ejected is large and the steam injection speed is fast, and it can also ensure that the nozzle 102 is not easily blocked by scale, thereby improving the working reliability of the nozzle 102. The diameter of the nozzle 102 may include one of the following: 0.5 mm, 0.6 mm, 0.63 mm, 0.68 mm, 0.7 mm, 0.71 mm, 0.74 mm, 0.76 mm, 0.79 mm, 0.8 mm, 0.82 mm, 0.83 mm, 0.85 mm, 0.87 mm, 0.9 mm, 0.92 mm, 0.94 mm, 0.96 mm, 0.98 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, or any other value between 0.5 mm and 1.5 mm. In this embodiment, the diameter of the nozzle 102 is preferably 0.8 mm. Nozzle 102 with this diameter can eject a large amount of steam and the steam can be ejected at a fast speed.

[0067] In one embodiment, the second cross-section of channel 101 is rectangular (e.g., Figure 3 and Figure 9As shown in the cross-sectional shape, the rectangular channel 101 is easy to manufacture, install, and maintain, and allows for easier inspection and cleaning, thus ensuring smooth steam flow. Along the third direction (i.e., the direction indicated by arrow Z in the figure, which is the width direction of the shell 11), the width of the second cross-section is L1, and along the second direction, the length of the second cross-section is L2 (L2 is the depth of the steam outlet passage 012 of channel 101 along the second direction). The size of L1 is not less than 1.4mm and not more than 2mm. Therefore, when the width L1 of channel 101 is within the aforementioned suitable range, channel 101 will not be too narrow, allowing for sufficient steam to pass through. Conversely, channel 101 will not be too wide, ensuring a higher steam pressure entering channel 101 while maintaining a constant steam volume. Under higher steam pressure, stubborn stains will experience greater steam pressure during the process of the nozzle 102 spraying steam onto the surface to be cleaned. This makes it easier for the stubborn stains to soften, dissolve, and loosen under the action of steam. Subsequently, when the roller component 31 passes over the stubborn stains, the stubborn stains will be more easily cleaned by the roller component 31, thereby improving the cleaning effect of the roller component 31 on stubborn stains. The shape of the second cross-section can also be trapezoidal, polygonal, semi-circular, etc.

[0068] In this embodiment, the size of L1 may include one of the following: 1.4mm, 1.41mm, 1.45mm, 1.48mm, 1.5mm, 1.52mm, 1.54mm, 1.57mm, 1.6mm, 1.61mm, 1.63mm, 1.65mm, 1.67mm, 1.7mm, 1.72mm, 1.74mm, 1.76mm, 1.79mm, 1.8mm, 1.81mm, 1.83mm, 1.85mm, 1.87mm, 1.9mm, 1.92mm, 1.94mm, 1.97mm, 2mm, or any other value between 1.4mm and 2mm.

[0069] like Figure 3 As shown, the length L2 of the second cross-section of channel 101 is not less than 3 mm and not more than 4 mm, thereby further ensuring that channel 101 can accommodate a large amount of steam and that the steam can be rapidly ejected through nozzle 102 under a large steam pressure. The size of L2 may include one of the following: 3 mm, 3.1 mm, 3.12 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.54 mm, 3.6 mm, 3.7 mm, 3.76 mm, 3.8 mm, 3.9 mm, 4 mm, or any other value between 3 mm and 4 mm.

[0070] Specifically, in this embodiment, when the radius of the nozzle 102 is R = D / 2, the area of ​​the first cross-section is S1 = π × R. 2Where "×" represents the multiplication symbol. When the width of channel 101 is L1 and the length is L2, the area of ​​the second cross-section is S2 = L1 × L2. Therefore, the area ratio... For example, when the diameter of the steam nozzle 102 is 0.8 mm, the steam inlet area S1 of a single nozzle 102 is about 2.01 square millimeters, and when S2 is 1.4 mm × 3.7 mm, the area ratio P is 38.8%.

[0071] In one embodiment of this invention, channel 101 can be a single-channel structure with an area S2 that meets the above requirements (e.g., Figure 8 (As shown in the flow channel structure), in this case, the second cross-section is the cross-section of the channel 101 itself in the single flow channel structure. For example... Figures 3 to 5 as well as Figure 7 As shown, in another embodiment, the channel 101 includes an inlet steam channel 011 and at least one outlet steam channel 012. Along a third direction, the outlet steam channel 012 is located on one side of the inlet steam channel 011. One end of the inlet steam channel 011 is connected to the connecting member 12, and a connecting port 013 is provided between the other end of the inlet steam channel 011 away from the connecting member 12 and the outlet steam channel 012. The connecting port 013 is located in the middle of the outlet steam channel 012 and is connected to it. Multiple nozzles 102 are located at the bottom of the outlet steam channel 012 and are connected to it, thus forming a labyrinthine channel 101 structure. In this case, the second cross-section is the cross-section of the outlet steam channel 012. Therefore, the steam generated by the steam supply assembly 20 can be guided through the connecting member 12 to the inlet steam channel 011, and then from the inlet steam channel 011 to the outlet steam channel 012 through the connecting port 013. Since the connecting port 013 is located in the middle of the steam outlet channel 012 (i.e., the distance from the connecting port 013 to the two opposite ends of the steam outlet channel 012 is equal along the first direction), when a certain amount of steam flows along the steam inlet channel 011 to the connecting port 013, it can ensure that the steam is evenly distributed to the opposite sides of the steam outlet channel 012 along the first direction, improving the uniformity of the steam amount in various parts of the steam outlet channel 012 and avoiding less steam on the side closer to the connector than on the side farther from the connector. Therefore, the amount of steam ejected from the multiple nozzles 102 connected to the steam outlet channel 012 is basically consistent, allowing each part of the stubborn stains and / or larger stubborn stains corresponding to the housing 11 on the surface to be cleaned to come into contact with more steam, improving the melting and loosening efficiency of the stubborn stains.

[0072] To prevent steam from flowing in large quantities into one side of the steam outlet channel 012 at the connection port 013 due to inertia, this embodiment also includes a partition structure within the channel 101. Along a third direction, the partition structure is disposed within the steam outlet channel 012, dividing it into a first channel segment 121 and a second channel segment 122. The partition structure is positioned opposite to the connection port 013 and has a first gap between it and the opposite sides of the connection port 013 along the first direction. The first channel segment 121 and the second channel segment 122 are respectively connected to the steam inlet channel 011 through the first gap. Therefore, this embodiment provides a separation structure at the connection port 013. This separation structure can divert the steam entering the first flow channel section 121 and the second flow channel section 122 from the steam inlet channel 011. The steam flowing from the steam inlet channel 011 can enter the first flow channel section 121 and the second flow channel section 122 evenly along the corresponding first gap. That is, the amount of steam entering the first flow channel section 121 and the second flow channel section 122 is basically the same, ensuring that the steam will not rush to the first flow channel section 121 in large quantities due to the action of motion inertia, thereby further improving the uniformity of the amount of steam in each part of the steam outlet channel 012.

[0073] In some embodiments, the partition structure may include a baffle plate installed at the communication port 013. For example... Figure 4 and Figure 7 As shown, the partition structure may also include a protrusion 014. Along a third direction, the protrusion 014 protrudes from the inner wall surface of the steam outlet channel 012 on the side away from the steam inlet channel 011. Along the first direction, the projected outer contours of the sidewalls of the protrusion 014 on opposite sides along the second direction are both arc-shaped. The first gap is located between the opposite sides of the protrusion 014 and the inner side of the connecting port 013. In this embodiment, by providing a protrusion 014 on the inner wall surface of the steam outlet channel 012, when setting the first outer shell 111 of the housing 11, the protrusion 014 can be integrally formed on the inner wall surface of the steam outlet channel 012, which facilitates processing, reduces the assembly steps of the housing 11, and thus improves the assembly efficiency of the housing 11. Secondly, since the projected outer contours of the sidewalls of the protrusion 014 on opposite sides along the second direction are both arc-shaped, the resistance encountered by steam entering the first flow channel section 121 and the second flow channel section 122 can be reduced, improving the smoothness of steam diversion to the two flow channel sections.

[0074] In this embodiment, please refer to Figure 4 The channel 101 is provided with a first protrusion 015 and a second protrusion 016. The first protrusion 015 and the second protrusion 016 are located on opposite sides of the channel 101 along its own length. The first protrusion 015 and the second protrusion 016 separate the channel 101 into a steam inlet channel 011 and a steam outlet channel 012, and form a connecting opening 013 connecting the steam inlet channel 011 and the steam outlet channel 012. The first gap is located between the protrusion 014 and the first protrusion 015 and the second protrusion 016.

[0075] The connecting member 12 can be disposed at one end of the housing 11 along a first direction and communicate with the steam inlet channel 011. The steam inlet channel 011 has a width along a third direction. Along the first direction, the width of the steam inlet channel 011 on the side near the connecting member 12 is greater than the width on the side away from the connecting member 12. This ensures that the steam inlet channel 011 can accommodate a larger amount of steam from the connecting member 12, and then guide it to the steam outlet channel 012 through the steam inlet channel 011. Furthermore, when a larger amount of steam accumulates on the side of the steam inlet channel 011 near the connecting member 12, the pressure on the steam near the connection port 013 of the steam inlet channel 011 can be increased, thereby accelerating the flow of steam along the connection port 013 into the steam outlet channel 101. The width of the wider side of the steam inlet channel 011 gradually decreases in the direction away from the connecting member until it is equal to the width of the side of the steam inlet channel 011 away from the connecting member 12. This increases the flow velocity of steam from the side of the steam inlet channel 011 near the connecting member 12 to the connecting port 013, increases the flow velocity of steam in the channel 101, and thus increases the injection efficiency of steam ejected from the nozzle 102.

[0076] The connecting member 12 can be a tubular connector to facilitate the connection between the connector and the steam outlet of the steam supply assembly 20.

[0077] like Figures 1 to 3 As shown, the housing 11 in this embodiment includes a first outer shell 111 and a second outer shell 112 connected to each other. A channel 101 is disposed on the side of the first outer shell 111 near the second outer shell 112. A connecting member 12 is located at one end of the first outer shell 111 along its length. The second outer shell 112 can be detachably fastened to the first outer shell 111 via a fastening structure 40 and covers the channel 101. Thus, after machining the groove forming the channel 101 and the first protrusion 015 and the second protrusion 016 on the first outer shell 111, the second outer shell 112 can be fastened together with the first outer shell 111, making assembly efficient and convenient. The detachability of the first and second outer shells 111 also facilitates disassembling the housing 11 to maintain and clean the channel 101 and the nozzle 102, removing accumulated scale and other solid stains.

[0078] like Figure 3 , Figure 4 To the diagram Figure 6 As shown, the fastening structure 40 includes an annular flange 41 and an annular groove 42. The annular flange 41 is disposed on the side of the first housing 111 near the second housing 112 and surrounds the outer periphery of the channel 101. The annular groove 42 is disposed on the side of the second housing 112 near the first housing 111 and corresponds to the annular flange 41. The annular flange 41 is adapted to the annular groove 42 and is inserted into the annular groove 42. Figure 3The first outer shell 111 and the second outer shell 112 are slightly misaligned during assembly (this problem does not exist in actual assembly). As a result, not only are the first outer shell 111 and the second outer shell 112 snapped together, but the fit between the annular flange 41 and the annular groove 42 can also seal the channel 101 to prevent steam leakage.

[0079] like Figure 4 This is a schematic diagram of the overall structure of channel 101 when there is only one steam outlet channel 012 in this embodiment. When the steam distribution component 10 is installed in the cleaning equipment 00, along the third direction, the steam outlet channel 012 can be specifically located on the side of the steam inlet channel 011 close to the roller component 31. Then, the nozzle 102 connected to the steam outlet channel 012 sprays steam to soften stubborn stains into ordinary stains that are easy to clean. The ordinary stains can then be cleaned in time by the roller component 31.

[0080] like Figure 7 As shown, the steam outlet channel 012 in this embodiment may also include two channels. Along the third direction, the two steam outlet channels 012 are located on opposite sides of the steam inlet channel 011, and a connecting port 013 is provided between the two steam outlet channels 012 and the steam inlet channel 011. Figure 7 The arrows in each flow channel indicate the flow direction of steam from the inlet flow channel 011 to the outlet flow channel 012. Since the roller component 31 is installed on the third-direction side of the steam distribution component 10, during the forward movement of the cleaning equipment 00, steam can first be sprayed onto stubborn stains through the nozzles 102 in the outlet flow channel 012 away from the roller component 31. When the outlet flow channel 012 near the roller component 31 passes over the stubborn stains, steam continues to be sprayed onto the stubborn stains through the nozzles 102 connected to itself. Thus, the stubborn stains are sprayed with steam at least twice, which will make the stubborn stains melt and loosen more thoroughly, and the stubborn stains will be cleaned more thoroughly when the roller component 31 passes over them.

[0081] Please see Figures 3 to 5Along the second direction, a first groove 103 is provided between the bottom surface of the channel 101 and the nozzle 102, connecting the channel 101 and the nozzle 102. Along the second direction, the first groove 103 has a third cross-section, which gradually decreases in size towards the nozzle 102. Therefore, the side of the nozzle 102 closest to the channel 101 can accumulate more steam through the first groove 103, increasing the steam pressure of the nozzle 102. Higher steam pressure results in stronger steam action on stubborn stains, facilitating more thorough stain removal and improving the cleanliness of the surface. The accumulation of steam in the first groove 103 before ejection also increases the coverage area of ​​the ejected steam on stubborn stains and increases the steam velocity, thereby increasing the impact force of the steam on stubborn stains, making them easier to soften, dissolve, and loosen.

[0082] In this embodiment, the axis of the nozzle 102 is parallel to the second direction, so that the nozzle 102 sprays steam vertically onto the surface to be cleaned, allowing the steam to come into contact with stubborn stains at a closer distance and increasing the impact force of the steam on the stubborn stains.

[0083] Please see Figure 9 Along a third direction, the housing 11 includes a first side 104 and a second side 105 disposed opposite to each other. The axis of the nozzle 102 is inclined toward the direction closer to the second side 105. When the housing 11 is mounted on one side of the roller component 31, the second side 105 is located on the side of the housing 11 away from the roller component 31, while the first side 104 is located on the side closer to the roller component 31. As the cleaning device 00 moves forward (the direction of movement is parallel to the third direction, specifically from the first side 104 to the second side 105), because the axis of the nozzle 102 is inclined toward the direction closer to the second side 105, the steam ejected from the nozzle 102 is generally sprayed forward at an angle away from the first side 104 onto the stubborn stains. In other words, steam can be sprayed onto stubborn stains before the nozzle 102 moves forward under the drive of the cleaning device 00, so that the stubborn stains come into contact with the steam in advance to soften and loosen them so that the roller component 31 can clean them. This also prevents some of the stubborn stains from re-condensing due to the long time interval between the contact time between the stubborn stains and the steam and the time when the roller component 31 moves forward to the stubborn stains.

[0084] The angle between the axis of nozzle 102 and the second direction (e.g.) Figure 9The included angle α shown is not less than 10° and not greater than 30°. Therefore, during the process of the nozzle 102 obliquely spraying steam towards the stubborn stain in a direction away from the first side 104, it is ensured that the amount of steam contacting the stubborn stain is sufficient, and that the stubborn stain is not prevented from being sprayed prematurely due to an excessively large or small angle of inclination of the nozzle 102's axis. The included angle between the axis of the nozzle 102 and the second direction may include one of the following: 10°, 10.5°, 11°, 12°, 13°, 14°, 15°, 15.3°, 15.6°, 16°, 17°, 18°, 19°, 20°, 21°, 21.4°, 22°, 23°, 24°, 25°, 25.3°, 25.7°, 26°, 27°, 28°, 29°, 30°, or any other angle value between 10° and 30°.

[0085] With the included angle α of the nozzle 102 not less than 10° and not greater than 30°, the following verification tests were conducted in this embodiment to verify the steam injection effect of the nozzle 102:

[0086] 21) When 0 ≤ α < 10°, the dimensions of the wetted area formed on the surface to be cleaned by the steam sprayed from nozzle 102 are: ① 22.5 * 31.5; ② 22 * ​​32; ③ 22 * ​​31. Disadvantage: Nozzle 102 can only spray onto the stain when it reaches directly above it, leaving insufficient time for the stain to completely dissolve, making stubborn stains difficult to clean. Dimensions are measured in millimeters.

[0087] 22) When 10°≤α≤30°, the dimensions of the wetted area formed by the steam sprayed from nozzle 102 onto the surface to be cleaned are: ①23*36; ②22.5*35.5; ③24*36. Advantages: The steam sprayed from nozzle 102 covers a larger area on the surface to be cleaned. Since nozzle 102 can spray steam onto stains ahead of them, the stains have sufficient time to dissolve, making it easier to clean stubborn stains.

[0088] 23) When α > 30°, the dimensions of the wetted area formed by the steam sprayed from the nozzle 102 onto the surface to be cleaned are: ① 15*31; ② 14.5*30.5; ③ 14.5*31.5. Disadvantages: The angle of the nozzle 102 is too large, and some of the steam will be sprayed towards the bottom cover 02 and the middle sweeping component 50 of the cleaning equipment 00, resulting in a large amount of steam loss and insufficient steam sprayed onto the stains, which is not conducive to the roller component 31 cleaning the stains. Secondly, the distance between the steam sprayed onto the ground and the roller component 31 is too far and narrow, and the stains will solidify after dissolving for too long, which is also not conducive to the roller component 31 cleaning the stains.

[0089] As can be seen from the above measurements, the size of the wetted area is larger when 10°≤α≤30° than when 0≤α<10° and α>30°, allowing sufficient time for the stains to dissolve and facilitating the cleaning of the roller component 31 of the cleaning equipment 00.

[0090] Furthermore, the steam distribution component 10 in this embodiment also includes a guide column 13, which protrudes from the bottom surface of the housing 11 along the second direction. When the cleaning device 00 includes a main housing component 01 and a bottom cover 02, the bottom cover 02 can be fastened to the bottom of the main housing component 01, and the steam distribution component 10 is installed between the bottom of the main housing component 01 and the bottom cover 02. The bottom cover 02 can provide stable support and protection for the steam distribution component 10, improving the structural stability of the steam distribution component 10 in the cleaning device 00. The bottom cover 02 can be provided with a clearance hole 021 to avoid the guide column 13, so that the guide column 13 can guide the steam ejected from the nozzle 102 to the outside of the bottom cover 02 and spray it onto stubborn stains.

[0091] like Figure 3 As shown, a second groove 131 is provided inside the flow guide column 13, and a protrusion 132 is provided near the bottom of the groove 131 on the housing 11. A third groove 133 is provided on the protrusion 132, and the third groove 133 communicates with the nozzle 102 near the bottom of the housing 11. Along the second direction, the depth of the second groove 131 is greater than the height of the protrusion 132. Thus, the flow guide column 13 constitutes a double-layer flow guide structure. The flow guide column 13 with this structure has the following functions:

[0092] 1) Due to the high heat generated when the steam is ejected, some of the steam will rise in the second direction. If only the inner nozzle 102 is present, the steam will enter the main housing component 01 of the cleaning device 00 through the gap between the nozzle 102 and the bottom cover 02. After cooling, the steam will generate water droplets, which can easily damage the components installed inside the main housing component 01. However, the double-layered guide column 13, after the steam from the nozzle 102 comes out from the second groove 131, will block the upward-moving (i.e., the direction away from the surface to be cleaned) steam from the components by the wall of the bottom of the first groove 103. The steam will then change its direction of movement and be ejected to the outside of the bottom cover 02, thus effectively solving the problem of steam seeping into the main housing component 01 and causing damage to the cleaning device 00.

[0093] 2) If the nozzle 102 alone emits steam at an excessively high temperature, it could cause burns if the user accidentally touches the nozzle surface. In this embodiment, the guide column 13 adopts a double-layer structure. Since the depth of the first groove 103 is greater than the height of the protrusion 132, the temperature of the steam flowing to the end of the groove wall of the first groove 103 away from the shell 11 will be reduced, which helps to prevent the user from being burned.

[0094] like Figure 3As shown, the cross-sectional area of ​​the third groove 133 along the first direction gradually increases in the direction away from the housing 11, forming an overall flared shape. Therefore, the flared expansion structure of the third groove 133 can effectively reduce the resistance of the steam flow process and improve the overall efficiency of steam injection. Furthermore, the flared expansion structure can also expand the steam injection range, allowing the steam to be more evenly distributed on stubborn stains after being ejected, avoiding the problem of excessive concentration of steam in stubborn stains while insufficient distribution in other areas, thus improving the uniformity and effectiveness of steam utilization. In addition, the third groove 133 of this structure also facilitates the user's observation of nozzle blockage, allowing the user to promptly remove any accumulated impurities and dirt.

[0095] In particular, along the second direction, the end of the second groove 131 away from the housing 11 is higher than the end of the protrusion 132 away from the housing 11 by a certain height (e.g., Figure 3 The depth of H shown is not less than 1.5mm and not more than 3mm. When a user accidentally touches the guide column 13 at this height range, the steam flowing from the second groove 131 is unlikely to burn the user. The depth of the second groove 131 may be one of the following: 1.5mm, 1.6mm, 1.65mm, 1.7mm, 1.71mm, 1.73mm, 1.78mm, 1.8mm, 1.83mm, 1.86mm, 1.87mm, 1.9mm, 1.95mm, 2mm, 2.1mm, 2.3mm, 2.5mm, 2.7mm, 3mm, or any other value between 1.5mm and 3mm.

[0096] There is a first gap (e.g., between the outer peripheral surface of the protrusion 132 and the inner wall surface of the second groove 131) Figure 3 As shown in J), the first gap can accommodate and block some of the upward-moving steam. The maximum value of the first gap is not less than 1 mm and not more than 1.5 mm. Specifically, the maximum value of the first gap may include one of the following: 1 mm, 1.1 mm, 1.11 mm, 1.13 mm, 1.16 mm, 1.18 mm, 1.2 mm, 1.22 mm, 1.24 mm, 1.27 mm, 1.3 mm, 1.31 mm, 1.34 mm, 1.36 mm, 1.38 mm, 1.4 mm, 1.42 mm, 1.43 mm, 1.45 mm, 1.47 mm, 1.5 mm, or any other value between 1 mm and 1.5 mm.

[0097] In this embodiment, the guide column 13 can be a single-layer structure, which can be connected to the nozzle 102 only through the bottom of the second groove 131. The single-layer structure of the guide column 13 can also prevent the user from being burned due to direct contact with the nozzle 102.

[0098] Please see Figures 10 to 12The second embodiment of this utility model also provides a cleaning device 00, which includes a steam mechanism. The steam mechanism includes a steam distributor 10 and a steam supply assembly 20. The steam supply assembly 20 includes a steam generator 21 and a water supply component. The steam generator 21 is connected between the connecting member 12 of the steam distributor 10 and the water supply component. For details on the structure of the steam distributor 10, please refer to the content provided in the first embodiment of this utility model, which will not be repeated here.

[0099] The cleaning device 00 also includes a cleaning assembly 30, which is mounted on the bottom of the cleaning device 00. The cleaning assembly 30 includes a roller component 31 and a self-cleaning component 32, with the self-cleaning component 32 positioned on one side of the roller component 31 to clean it. Along the forward direction of the cleaning device 00, a steam distributor 10 is located at the front of the cleaning assembly 30, and along a second direction, the self-cleaning component 32 is located between the steam distributor 10 and the top of the cleaning device 00. The arrangement of the self-cleaning component 32 and the steam distributor 10 in the cleaning device 00 improves the space utilization of the cleaning device 00 and enhances the overall compactness of the cleaning device 00 structure. Furthermore, because the steam distributor 10 is located at the bottom of the device body and close to the surface to be cleaned, the spray force of the steam emitted by the steam distributor 10 on stubborn stains can be increased, as can the amount of steam in contact with the stubborn stains, thereby ensuring that the stubborn stains are sufficiently softened and dissolved.

[0100] The cleaning equipment 00 also includes a main housing component 01 and a bottom cover 02. The steam generator 21 and water supply component of the steam mechanism can both be installed inside the main housing component 01. In this embodiment, the water supply component includes a clean water tank 22 and a water pump 23, with the water pump 23 connecting the clean water tank 22 and the steam generator 21. The water pump 23 delivers water from the clean water tank 22 to the steam generator 21, which heats the water to generate steam and transmits the steam through the connecting member 12 to the channel 101 of the steam distribution component 10.

[0101] The cleaning device 00 in this embodiment also includes a central sweeping assembly 50, which is installed at the bottom of the cleaning device 00. A steam distributor 10 is located between the central sweeping assembly 50 and the roller assembly 31, with the steam distributor 10 closer to the roller assembly 31 than to the central sweeping assembly 50. The central sweeping assembly 50 typically includes a roller brush, a drive mechanism, and a cover structure for mounting the roller brush on the cleaning device 00. The roller brush can rotate under the drive mechanism to sweep away debris on the surface to be cleaned during rotation. The cleaning device 00 is equipped with a dust box for collecting the debris swept up by the roller brush.

[0102] In this embodiment, the steam distributor 10 is installed between the intermediate sweeping assembly 50 and the roller assembly 31, and the steam distributor 10 is closer to the roller assembly 31 than the intermediate sweeping assembly 50. This ensures that after the steam distributor 10 sprays steam onto the stubborn stains, the roller assembly 31 can clean the stubborn stains in a timely manner. This is because if the steam distributor 10 is placed far away from the roller assembly 31, or even on the side of the intermediate sweeping assembly 50 far from the roller assembly 31, the roller assembly 31 will only reach the stubborn stains after the steam distributor 10 has sprayed steam onto them for a period of time. At this time, the stubborn stains may condense again under the action of cold air, becoming even more stubborn, which will reduce the cleaning effect of the roller assembly 31 on the stubborn stains. Secondly, since the dust box collects garbage under vacuum conditions, the rotation of the roller brush will disturb the surrounding airflow. This airflow can easily weaken the force of the steam sprayed onto the stubborn stains, or even change the direction of the steam spray, reducing the amount of steam sprayed onto the stubborn stains. In this embodiment, the steam distribution component 10 is positioned close to the roller component 31 to avoid the aforementioned adverse effects caused by the airflow disturbance when the sweeping component 50 cleans up debris.

[0103] The self-cleaning component 32 in this embodiment includes a water spray component 321 and a squeegee component 322. Along the forward direction of the cleaning device 00, the water spray component 321 is located between the squeegee component 322 and the steam distributor 10.

[0104] The roller assembly 31 includes a drive unit, a roller, and a mop. The roller is connected to the drive unit and can rotate around its own axis under the drive of the drive unit. The mop is laid on the outer circumference of the roller. When the water spraying component 321 includes a mounting plate 211 and a snap plate 212, the drive unit of the roller assembly 31 is connected to the extension of the mounting plate 211, which facilitates assembly and avoids complicating the overall structure of the cleaning assembly 30. The mounting plate 211 is provided with a water supply channel and multiple water spray holes. The water supply channel is laid along the axial direction of the roller (the axial direction of the roller is the length direction of the roller assembly 31), and the snap plate 212 is set on the mounting plate 211 and covers the water supply channel. The water spray holes are located on the side of the mounting plate 211 near the roller and communicate with the water supply channel. After clean water is introduced into the water supply channel, clean water can be sprayed onto the roller through the water spray holes to fully wet the mop on the roller. Along the forward direction of the cleaning equipment 00, the squeegee 322 is connected to the side of the mounting plate 211 away from the steam distributor 10 and abuts against the roller assembly 31. During the rotation of the roller, the squeegee 322 scrapes off the wastewater and debris on the mop, thereby cleaning the roller component 31. The cleaning device 00 also includes a wastewater box 60. The cleaning component 30 is located between the wastewater box 60 and the steam spray component. The drain outlet of the squeegee 322 is opposite to the water collection tank of the wastewater box 60, or the drain outlet of the squeegee 322 is connected to the water storage chamber in the wastewater box 60 through a pipe, so that the wastewater scraped off by the squeegee 322 is discharged into the wastewater box 60. In this embodiment, the spray component 321 is located between the squeegee 322 and the steam distributor 10. While cleaning the roller component 31, it also improves the space utilization of the installation space in the cleaning device 00. Within a limited space, the cleaning device 00 can achieve self-cleaning of the roller component 31 during forward movement and softening and loosening of stubborn stains through the steam distributor 10.

[0105] 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.

[0106] 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.
