[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] Combination Figure 1 This application provides a cleaning system 1. The cleaning system 1 includes a base station 200 and a cleaning device 100. The cleaning device 100 can dock at the base station 200. The cleaning device 100 can independently clean surfaces detached from the base station 200. The surfaces to be cleaned can be, for example, tiled floors, wooden floors, stone floors, or carpet surfaces, etc., and the specific type of surface to be cleaned is not specifically limited here. After the cleaning device 100 docks at the base station 200, the base station 200 can maintain the cleaning device 100. Specifically, the base station 200 can charge the cleaning device 100, store, replace, or clean cleaning tools. The base station 200 can also clean accumulated dirt from the cleaning device 100.

[0043] Combination Figure 2 , Figure 2This is a schematic diagram of the cleaning device 100 facing the surface to be cleaned. This application provides a cleaning device 100. The cleaning device 100 can be a sweeping robot, a mopping robot, or a combined sweeping and mopping robot, etc., without specific limitation. The cleaning device 100 includes a cleaning component 10 and a cleaning body 20. The cleaning body 20 is capable of moving on the surface to be cleaned. The cleaning component 10 is installed on the side of the cleaning body 20 facing the surface to be cleaned. The cleaning component 10 is capable of cleaning the surface. The cleaning device 100 can walk and move on the surface to be cleaned, and has a direction of travel during its movement. For example, the cleaning device 100 can walk and move on the surface to be cleaned via drive wheels 30. For example, if there are two drive wheels 30 and the two drive wheels 30 have no differential speed (i.e., the cleaning device 100 does not turn), its forward direction is the direction of travel. The cleaning device 100 may also be provided with guide wheels 40, which can assist the cleaning device 100 in turning.

[0044] It should be noted that, for ease of description in this embodiment, a first direction (X in the reference figure), a second direction (Z in the reference figure), and a third direction (Y in the reference figure) are introduced as references. The first direction is perpendicular to the travel direction of the cleaning device 100. The second direction is perpendicular to the first direction. In some embodiments, the second direction is perpendicular to the surface to be cleaned, and the third direction is perpendicular to both the first and second directions. In some embodiments, the third direction is also the travel direction of the cleaning device 100.

[0045] Combination Figure 2 and Figure 3 This application provides a cleaning component 10. The cleaning component 10 includes a mounting bracket 11 and multiple brush head assemblies 12. The mounting bracket 11 can serve as a mounting base for the cleaning component 10, and other components of the cleaning component 10 can be mounted on the mounting bracket 11. The mounting bracket 11 can also serve as a connecting body when the cleaning component 10 is installed with the cleaning body 20. That is, when the cleaning component 10 is installed on the cleaning body 20, it can be installed by directly or indirectly connecting the mounting bracket 11 to the cleaning body 20. The multiple brush head assemblies 12 are arranged along a first direction, and the multiple brush head assemblies 12 are rotatably connected to the mounting bracket 11 about their respective rotation axes. The rotation axes of the multiple brush head assemblies 12 are arranged along a second direction. The brush head assembly 12 includes a brush 121 (combined with...). Figure 7The brush head assembly 12 can clean the surface to be cleaned. By setting multiple brush head assemblies 12, the area that the cleaning assembly 10 can clean can be increased. By setting the brush head assembly 12 to be rotatable, the brush head assembly 12 can scrub the stains on the surface to be cleaned by rotating. The brush head assembly 12 includes a bristle 121. The bristle 121 is harder than a mop. By setting the bristle 121, the brush head assembly 12 can clean stains with stronger cleaning power, which helps to improve the cleaning power of the cleaning assembly 10.

[0046] In some embodiments, the brush 121 includes a plurality of bristles arranged in an alternating and / or parallel pattern. The parallel bristles may be arranged parallel to each other along a second direction. Parallel arrangement of bristles allows the brush 121 to maintain a relatively uniform cleaning force when in contact with the surface to be cleaned. This arrangement of the brush 121 is relatively simple to manufacture, has low cost, and provides stable cleaning results. The alternating bristles may be arranged in multiple different directions, with different bristles intersecting. The alternating arrangement of bristles increases the flexibility and adaptability of the brush 121, giving it good cleaning ability in different directions. The alternating arrangement of bristles allows for better contact with the surface to be cleaned, cleaning stains from multiple angles and reducing cleaning dead zones. In some embodiments, the plurality of bristles on the brush 121 may include either parallel or alternating bristles.

[0047] In some embodiments, the bristles are made of a non-hydrophobic material. A non-hydrophobic material can refer to a material that is not hydrophobic or is superhydrophobic. The non-hydrophobicity of a material can be evaluated by its hydrophobicity. In other words, the bristles have a certain degree of hydrophilicity. The non-hydrophobicity of the bristles can be determined by the contact angle between water molecules and the bristle material. The hydrophilicity of the bristles allows the surface to be wetted by water, enabling liquids to remain on the surface. This design increases the bristles' ability to clean liquid stains. When liquids such as water, tea, or coffee are spilled, the non-hydrophobic material of the bristles allows these liquids to be quickly absorbed onto the brush 121. Furthermore, the non-hydrophobic material of the bristles allows the cleaning solution to be evenly distributed on the surface of the brush 121. Thus, during the cleaning process, the cleaning solution can fully contact the surface to be cleaned, effectively removing dirt.

[0048] In some embodiments, the water absorption rate of the brush strip is less than a preset water absorption rate threshold. The water absorption rate threshold can be obtained through experience, experimentation, statistics, etc. The water absorption rate can be either mass absorption rate or volume absorption rate. Selecting a brush strip material based on the water absorption rate threshold allows the brush strip's water absorption rate to be controlled at a low value. This setting ensures that the brush strip absorbs very little liquid. Less liquid absorption reduces the impact of liquid adsorption on the brush strip material properties. The brush strip, without becoming heavy or soft due to moisture, maintains good elasticity and stiffness, resulting in more uniform friction when in contact with the surface to be cleaned, leading to better cleaning performance.

[0049] In some embodiments, the bristles are configured such that water bridges formed on the brush 121 due to surface tension do not detach at a rotational speed of at least 200 rpm. The rotational speed can also be 250 rpm, 300 rpm, 350 rpm, or 400 rpm, at which speeds the water bridges formed on the brush 121 due to surface tension also do not detach. When the brush 121 configured in this manner cleans a surface containing liquid debris, the surface tension allows the liquid to be adsorbed onto the brush 121 in the form of water bridges. These water bridges allow water molecules to adhere to the surface of the bristles, preventing the liquid from easily detaching from the brush 121 even during movement, thus effectively collecting liquid debris. When using cleaning fluid, the brush 121 configured in this manner allows the cleaning fluid to adhere better to the brush 121 and be evenly distributed.

[0050] In some embodiments, the bristle diameter of the bristles is between 0.05mm and 0.1mm. A bristle diameter that is too large makes it difficult to effectively clean narrow areas such as tile grout, wall corners, or the bottom of furniture. Furthermore, coarser bristles have poorer adsorption capacity for fine particulate matter (such as flour or dust particles) during cleaning. Conversely, bristles that are too thin have lower strength and are easily bent by external forces during cleaning, resulting in less friction when in contact with the surface being cleaned, and insufficient cleaning power for stubborn stains.

[0051] In some embodiments, the density of the multiple hair strips is 1000 f / cm. 2 ~2000f / cm 2 Between. For example, 1200f / cm 2 1500f / cm 2 Or 1700f / cm 2The density of the bristles refers to the number of fibers per square centimeter. If the bristle density is too high, the brush 121 will be thicker overall, with smaller gaps between adjacent bristles. This makes it difficult for the brush 121 to reach into crevices for effective cleaning, and also reduces its ability to clean small particles. If the bristle density is too low, the contact area between the brush 121 and the surface to be cleaned will be smaller, resulting in less friction during cleaning and reducing its ability to clean stubborn stains. A sparsely spaced bristle will also fail to effectively absorb and control the spread of liquids, allowing liquids to easily leak out from the gaps between the bristles.

[0052] Combination Figure 3 In some embodiments, the projections of two adjacent brush head assemblies 12 in a third direction at least partially overlap, and the third direction is perpendicular to the first and second directions. The third direction can be the travel direction of the cleaning device 100. The projection of the brush head assembly 12 in the third direction can be the projection of the portion of the brush head assembly 12 in contact with the surface to be cleaned in the third direction. Specifically, during the travel of the cleaning device 100, one brush head assembly 12 can form a corresponding cleaning area. By setting the projections of two adjacent brush head assemblies 12 to partially overlap in the third direction, the cleaning areas formed by the brush head assemblies 12 can overlap. In this way, the possibility of missed areas by the brush head assembly 12 can be reduced, which is beneficial to improving cleaning efficiency.

[0053] In some embodiments, adjacent brush head assemblies 12 are staggered in the third direction. That is, the distribution positions of adjacent brush head assemblies 12 in the third direction are different. For example, the first brush head assembly is positioned further forward in the third direction than the second brush head assembly; the second brush head assembly is positioned further back in the third direction than the third brush head assembly; the third brush head assembly is positioned further forward in the third direction than the fourth brush head assembly; and so on. This arrangement avoids multiple brush head assemblies 12 being in the same position in the third direction, and achieves overlap of the projected portions of two adjacent brush head assemblies 12 in the third direction through staggered distribution. Moreover, the staggered distribution can reduce the distribution size of multiple brush head assemblies 12 in the third direction, thereby reducing the volume of multiple brush head assemblies 12. One brush head assembly 12 can be responsible for cleaning one area of ​​the surface to be cleaned, while adjacent staggered brush head assemblies 12 can supplement the cleaning of another area. This staggered cleaning path ensures that the cleaning device 100 covers more of the surface to be cleaned during movement.

[0054] In some embodiments, the brush 121 is arranged in a disc shape, and the brushes 121 of two adjacent brush head assemblies 12 are in contact. By making the brushes 121 in contact with each other, the brush head assembly 12 can cover the portion between adjacent brush head assemblies 12, thereby further reducing the possibility of the brush head assembly 12 missing any areas.

[0055] In some embodiments, the number of brush head assemblies 12 is greater than or equal to three. By setting the number of brush head assemblies 12 to greater than or equal to three, the cleaning assembly 10 can cover a larger cleaning area in the first direction while its size in the third direction is not too large, thereby reducing the size of the cleaning assembly 10 in the third direction. Furthermore, by combining this with the aforementioned fact that the projections of the brush head assemblies 12 in the third direction at least partially overlap, the overlapping areas can be brushed multiple times, which helps to improve cleaning efficiency.

[0056] Optionally, among the three adjacent brush head assemblies 12, the pivots of the two brush head assemblies 12 located on either side in the first direction can form a reference line, and the pivot of the brush head assembly 12 located in the middle in the first direction is located on one side of the reference line. In a further embodiment, the number of brush head assemblies 12 is between five and eight, for example, six or seven. This arrangement allows the cleaning assembly 10 to cover a larger cleaning area in the first direction while ensuring that its size in the third direction is not too large, thereby reducing the size of the cleaning assembly 10 in the third direction, and also ensuring that its size in the third direction is not too small, thus guaranteeing cleaning efficiency.

[0057] Combination Figure 3 In some embodiments, the mounting bracket 11 is provided with a water-blocking portion 182, which is disposed on both sides of the plurality of brush head assemblies 12 along a first direction. The water-blocking portion 182 may be located on the side of the mounting bracket 11 facing the surface to be cleaned, and protrude from the mounting bracket 11 toward the surface to be cleaned. The water-blocking portion 182 can block liquid that may be flung to both sides during the rotation of the brush head assembly 12, so as to block the droplets as much as possible within the range that the brush head assembly 12 can clean, thereby reducing secondary pollution generated during the cleaning process.

[0058] Combination Figure 3 In some embodiments, the side of the brush head assembly 12 away from the center of the mounting bracket 11 moves in the direction of travel of the cleaning assembly 10 in the first direction, which is perpendicular to the first direction. That is, for each brush head assembly 12, the outer side of the brush head assembly 12 moves from back to front. "From back to front" can mean moving from the rear side of the travel direction to the front side of the travel direction. Figure 3 As shown by the arrow Figure 3The arrows near the rotation axis indicate the rotation direction of the corresponding brush head assembly 12, while the arrows near the outer side of the brush head assembly 12 indicate the lateral movement direction of the brush head assembly 12 (i.e., the outward component of the brush head assembly 12's rotation in the first direction). In this way, the front portion of the brush head assembly 12 in its direction of travel can, during rotation, throw the liquid as far as possible towards the center of the cleaning assembly 10, that is, the area covered by the cleaning area formed by the brush head assembly 12. Thus, the liquid thrown out by the rotating brush head assembly 12 can be cleaned again by the brush head assembly 12, reducing secondary contamination of the floor during the cleaning process. Figure 3 Taking the arrangement in the middle as an example, the two brush head assemblies 12 on the left can rotate clockwise, the two brush head assemblies 12 on the right can rotate counterclockwise, and the middle brush head assembly 12 can rotate either clockwise or counterclockwise. In this way, the brush head assemblies 12 on both sides can throw liquid towards the area that the cleaning assembly 10 can sweep in the direction of travel as it rotates.

[0059] Combination Figure 4 and Figure 5 In some embodiments, the cleaning component 10 further includes a drive component rotatably connected to a plurality of brush head assemblies 12. The brush head assemblies 12 in this embodiment are rotatably configured, and by being driven to rotate by the drive component, the brush head assemblies 12 can repeatedly scrub away stains during the movement of the cleaning device 100, thereby achieving the cleaning of the stains.

[0060] Specifically, the drive assembly includes a drive motor 16 and a transmission mechanism. The drive motor 16 is connected to multiple brush head assemblies 12 via the transmission mechanism. The motor 16 can generate rotation as a power source, and the transmission mechanism can transmit the rotation generated by the power source to the brush head assemblies 12. The transmission mechanism can change the speed, torque, or direction of rotation during transmission, which is not specifically limited here.

[0061] In some embodiments, the transmission mechanism includes a plurality of transmission components 13, which correspond to a plurality of brush head assemblies 12. By assigning a plurality of transmission components 13 to a brush head assembly 12, the rotational speed, direction of rotation, and torque of the brush head assembly 12 can be controlled relatively independently by driving the corresponding transmission components 13 through a drive component. In this way, different brush head assemblies 12 can be designed with different transmission ratios or different numbers of transmission components 13 according to their functions or positions, enabling the brush head assemblies 12 to have different directions of rotation and rotational speeds. One of the transmission components 13 is circumferentially connected to the corresponding brush head assembly 12, thereby enabling the drive component to drive the brush head assembly 12 to rotate through the transmission component 13. The drive motor 16 is connected to at least one of the plurality of transmission components 13. The plurality of transmission components 13 can be interconnected, so that driving at least one transmission component 13 can drive the plurality of transmission components 13 to rotate together. Optionally, the transmission components 13 can share the same parts.

[0062] In some embodiments, the transmission assembly 13 includes a first transmission gear 131 and a second transmission gear 132. The second transmission gear 132 is circumferentially connected to the brush head assembly 12. By configuring the first transmission gear 131 and the second transmission gear 132, the power generated by the motor 16 can be transmitted to the brush head assembly 12 to drive the brush head assembly 12 to rotate. Optionally, the rotation axis of the second transmission gear 132 coincides with the rotation axis of the corresponding brush head assembly 12. In other words, the second transmission gear 132 and the brush head assembly 12 are coaxially arranged and have the same rotational speed. The first transmission gear 131 can transmit the rotation generated by the motor 16 to the second transmission gear 132, and the second transmission gear 132 can drive the brush head assembly 12 to rotate. The first transmission gear 131 is circumferentially connected to the transmission assembly 13 corresponding to the adjacent brush head assembly 12. In other words, in addition to being connected to the corresponding second transmission gear 132, the first transmission gear 131 can also be connected to the first transmission gear 131 or the second transmission gear 132 corresponding to other brush head assemblies 12. Optionally, the second transmission gear 132 is configured in a one-to-one correspondence with the brush head assembly 12, and the first transmission gear 131 is capable of driving and connecting adjacent second transmission gears 132. Adjacent second transmission gears 132 can share the same first transmission gear 131 to form the aforementioned transmission assembly 13.

[0063] In some embodiments, the transmission assembly 13 may include only the second transmission gear 132, which is circumferentially connected to the brush head assembly 12. Adjacent second transmission gears 132 may be drive-connected to each other. The motor 16 may be drive-connected to at least one of the second transmission gears 132.

[0064] In some embodiments, the brush head assembly 12 is axially slidably connected to the second transmission gear 132. In other words, the brush head assembly 12 can float along the direction of the rotation axis. The surface to be cleaned may not be completely flat, with some undulations, small steps, thresholds, or obstacles. The floating brush head assembly 12 can adjust the contact angle and pressure with the surface to be cleaned according to the changes in the surface's height, allowing the brush head assembly 12 to fit as closely as possible to the surface. On the other hand, the brush head assembly 12 can generate a continuous tendency to move towards the surface to be cleaned through its own gravity or external force, thereby maintaining a certain pressure between the brush head assembly 12 and the surface. By maintaining a certain pressure between the brush head assembly 12 and the surface to be cleaned, the friction between the brush head assembly 12 and the surface to be cleaned can be increased, thereby improving the cleaning power of the surface to be cleaned.

[0065] Combination Figure 6 In some embodiments, the cleaning assembly 10 further includes a plurality of elastic elements 15, which correspond to a plurality of brush head assemblies 12. One of the elastic elements 15 is disposed between the corresponding transmission assembly 13 and the brush head assembly 12. By being disposed between the transmission assembly 13 and the brush head assembly 12, the elastic element 15 can prevent the brush head assembly 12 from moving closer to the mounting bracket 11 during the operation of the cleaning assembly 10. The elastic element 15 can elastically hold the brush head assembly 12 by elastic compression. The arrangement of the elastic element 15 allows the brush head assembly 12 to generate a holding force toward the surface to be cleaned while still having the function of sliding up and down, thereby enabling the cleaning assembly 10 to generate pressure when cleaning the surface. By maintaining a certain pressure between the brush head assembly 12 and the surface to be cleaned, the friction between the brush head assembly 12 and the surface to be cleaned can be increased, thereby improving the cleaning force on the surface to be cleaned.

[0066] In some embodiments, the transmission assembly 13 further includes an upper cover 14, which is disposed at one end of the second transmission gear 132, and an elastic member 15 is disposed between the upper cover 14 and the brush head assembly 12. The upper cover 14 can abut one end of the elastic member 15, and the other end of the elastic member 15 can abut against the brush head assembly 12. The upper cover 14 is fixed in the direction of the rotation axis of the brush head assembly 12, that is, the upper cover 14 does not slide on the rotation axis of the brush head assembly 12. In this way, during the cleaning process of the brush head assembly 12 on the surface to be cleaned, the elastic member 15 can generate elastic compression, thereby applying a holding force towards the surface to be cleaned to the brush head assembly 12, thereby improving the cleaning force of the brush head assembly 12 on the surface to be cleaned. Optionally, the upper cover 14 is mounted on the second transmission gear 132 and can rotate with the second transmission gear 132. Optionally, the upper cover 14 may not rotate with the second transmission gear 132, but may be directly or indirectly mounted on the mounting bracket 11.

[0067] In some embodiments, the cleaning assembly 10 further includes a housing 19, in which at least a portion of the motor 16, the transmission assembly 13, and the brush head assembly 12 can be housed. The housing 19 can protect the rotation of the transmission assembly 13 and the motor 16, reducing the impact of hair or dust on the transmission.

[0068] Combination Figure 6 and Figure 7 In some embodiments, the brush head assembly 12 further includes a drive shaft 123, to which the brush 121 is connected. The drive shaft 123 is slidably engaged with the second drive gear 132 along the rotation axis of the brush head assembly 12, and is circumferentially connected to the second drive gear 132 about the rotation axis. In other words, in the second direction, the drive shaft 123 and the brush 121 can slide up and down, and the connection between the second drive gear 132 and the drive shaft 123 allows the drive shaft 123 to slide within a certain stroke. In the circumferential direction, the second drive gear 132 can drive the drive shaft 123, thereby driving the brush 121 to rotate, in order to clean the surface to be cleaned. Optionally, the circumferential transmission between the drive shaft 123 and the second drive gear 132 can be achieved through a spline or a square structure.

[0069] Specifically, in some embodiments, the second transmission gear 132 is provided with a sliding channel 1321. The transmission shaft 123 is slidably disposed within the sliding channel 1321. In this way, it is beneficial to keep the transmission shaft 123 and the second transmission gear 132 coaxially rotating, and this method can utilize the space in the middle of the second transmission gear 132, which helps to reduce the space occupied by the transmission shaft 123 and facilitates a more compact design of the cleaning assembly 10.

[0070] Furthermore, a limiting flange 1322 is provided within the sliding channel 1321, and the drive shaft 123 has a limiting protrusion 1232 that matches the limiting flange 1322. The limiting protrusion 1232 is disposed between the limiting flange 1322 and the upper cover 14. By providing the limiting flange 1322 and the limiting protrusion 1232, the drive shaft 123 can be prevented from disengaging from the sliding channel 1321.

[0071] In some embodiments, the drive shaft 123 is provided with a receiving groove 1231, and the elastic member 15 is at least partially disposed within the receiving groove 1231. One end of the elastic member 15 abuts against the bottom of the receiving groove 1231, and the other end of the elastic member 15 abuts against the upper cover 14. By providing the receiving groove 1231 to accommodate the elastic member 15, the structure of the drive shaft 123 can be used to accommodate the elastic member 15, thereby reducing the space occupied by the elastic member 15 and improving space utilization. On the other hand, by accommodating the elastic member 15 in the receiving groove 1231, when the brush head assembly 12 is subjected to a large force approaching the upper cover 14, the elastic member 15 can be elastically compressed into the receiving groove 1231, and then the brush head assembly 12 is rigidly limited by the abutment between the groove wall of the receiving groove 1231 and the upper cover 14.

[0072] In some embodiments, the cleaning assembly 10 further includes a squeegee assembly 181, which is disposed behind the plurality of brush head assemblies 12 along the direction of travel. By providing the squeegee assembly 181, residual liquid or stains on the surface to be cleaned after being cleaned by the brush head assembly 12 can be collected for further cleaning. This method also enables the cleaning device 100 to quickly gather water or stains, reducing the re-spread of stains.

[0073] In some embodiments, the wiping assembly 181 includes a base 1813 and a first wiping strip 1811 and a second wiping strip 1812 mounted on the base 1813. The first wiping strip 1811 and the second wiping strip 1812 are arranged side by side in the direction of travel. The base 1813 has a suction chamber that communicates with the gap between the first wiping strip 1811 and the second wiping strip 1812. In this way, during wiping, the wiping assembly 181 can draw liquid from the gap between the first wiping strip 1811 and the second wiping strip 1812 into the suction chamber, and then store the wastewater in the wastewater tank of the cleaning device 100. This method helps to reduce water residue on the floor as quickly as possible, allowing the surface to be cleaned to dry more quickly.

[0074] Combination Figure 7 In some embodiments, the brush head assembly 12 further includes a rotating bracket 122, on which the brush 121 is disposed. The rotating bracket 122 is connected to the drive shaft 123. The rotating bracket 122 connects the brush 121 and the drive shaft 123, and provides mechanical support for the brush 121 and drives the brush 121 to rotate. The rotating bracket 122 and the drive shaft 123 may be integrally formed, or they may be connected by spline drive or by a connector; no specific limitation is made here.

[0075] Combination Figure 7In some embodiments, the rotating bracket 122 is provided with a clearance opening 1221, and the brush 121 has a clearance channel 1211 corresponding to the clearance opening 1221. The mounting bracket 11 is also provided with a water outlet 17 (in conjunction with...). Figure 3 The water outlet 17 is correspondingly provided with the clearance port 1221 and the clearance channel 1211. The water outlet 17 can spray cleaning liquid towards the surface to be cleaned. The cleaning liquid can be water, detergent, or disinfectant, etc., and there is no specific limitation here. The water from the water outlet 17 can be sprayed onto the surface to be cleaned through the clearance port 1221 and the clearance channel 1211.

[0076] Optionally, the number of water outlets 17 corresponds to the number of brush head assemblies 12, with each brush head assembly 12 having at least one water outlet 17. Optionally, the water outlets 17 are located within the inner perimeter of the projection of the brush 121 onto the mounting bracket 11, thereby enabling the water outlets 17 to spray cleaning fluid onto the cleaning area corresponding to the brush head assembly 12, and reducing the space occupied by the water outlets 17. The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the description and drawings of this application, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
