Abstract
Description
TECHNICAL AREA
[0001] The utility model relates to the field of household appliances and specifically to a self-driving robot. BACKGROUND TECHNOLOGY
[0002] With the proliferation of smart home products, automated cleaning devices, especially floor cleaning robots, have become an integral part of modern domestic life. Floor cleaning robots, through their autonomous navigation, cleaning route planning, and efficient cleaning functions, have significantly simplified housework and reduced physical strain.
[0003] Despite the continuous improvement in the cleaning performance of floor cleaning robots, the management of cleaning components remains a pressing problem. Especially in floor cleaning robots with integrated wet mopping functions, cleaning components such as wipers or rollers must be cleaned and dried promptly after use. Otherwise, bacterial growth can occur inside the cleaning element, significantly impairing the robot's cleaning performance. This can also lead to mold growth and other issues, necessitating frequent replacement of the cleaning element. To overcome the inconvenience of manually cleaning cleaning elements, state-of-the-art technology utilizes an air duct structure that generates an airflow to dry the cleaning element.In the prior art, these air duct systems typically use simple air ducts and air outlet openings directed towards the cleaning element, so that the airflow is directed straight from the air outlet onto the cleaning element for drying. The problem with this design is that the air duct structure cannot be designed with a sufficiently wide pipe diameter to adapt to the internal structures of the floor cleaning robot and the base station. This makes it difficult to completely cover the cleaning element with airflow when blowing onto it. Although this design offers the possibility of drying cleaning elements to some extent, the uneven distribution of the generated airflow across the surface of the cleaning elements leads to low drying efficiency and unsatisfactory results.This can even lead to certain areas continuing to overheat after drying, resulting in accelerated aging of these cleaning elements.
[0004] Therefore, the urgent question arises as to how the air duct structure can be designed so that the airflow is directed evenly onto the components to be treated. CONTENTS OF THE INSTRUCTION MANUAL
[0005] In order to solve at least one of the technical problems described above, a self-driving robot comprising a guide element is provided in accordance with one aspect of the present utility model. a guide element comprising an air inlet opening, an air outlet opening and a guide section;
[0006] The air inlet opening is detachably connected to the air supply device and receives the airflow generated by this air supply device.
[0007] The air outlet opening has a cross-sectional area larger than that of the air inlet opening and is directly aligned with the component to be treated in order to promote the airflow to the component being treated.
[0008] The guide section is arranged in the direction of flow between the air inlet opening and the air outlet opening in order to divide the airflow into several strands that are distributed along the longitudinal direction of the component to be treated, and to direct this airflow onto the surface of the component to be treated.
[0009] The self-driving robot provided in this utility model allows the airflow, guided by this element, to be distributed evenly across the component being treated, ensuring uniform processing. This prevents different areas of the component from being processed at different speeds due to uneven airflow, thus avoiding problems with the component and increasing processing efficiency.

SPECIFIC EXECUTION FORMS
[0010] To solve the aforementioned technical problems, a self-driving robot is provided in this utility model. The guiding element comprises, as in the Fig. 1 and Fig. 4 an air inlet opening 1, an air outlet opening 2 and a guide section.
[0011] The air inlet opening 1 is detachably connected to the air supply device and receives the airflow generated by this air supply device.
[0012] The air outlet opening 2 has a cross-sectional area larger than that of the air inlet opening 1 and is directed towards the component 3 to be treated in order to promote the airflow to the component 3 to be treated.
[0013] The guide section is arranged in the direction of flow between the air inlet opening 1 and the air outlet opening 2 in order to divide the airflow into several strands that are distributed along the longitudinal direction of the component 3 to be treated, and to direct this airflow onto the surface of the component 3 to be treated.
[0014] The self-driving robot provided in the present utility model allows the airflow, which is guided by this guide element, to be distributed evenly over the component 3 to be treated, so that the airflow treats the component 3 uniformly. This prevents different areas of the component 3 from being processed at different speeds due to uneven airflow, thereby avoiding problems with the component 3 and increasing processing efficiency.
[0015] During use, the guide element is detachably connected to the air supply device via the air inlet opening 1 to introduce the airflow generated by the air supply device into the interior of the guide element. The airflow enters the guide element through the air inlet opening 1 and therefore has a relatively small effective area. When the airflow encounters the guide section, the guide section can divide the airflow along the longitudinal direction of the component 3 to be treated into several streams, thereby increasing the effective area of the airflow and directing the airflow evenly onto the component 3 to be treated.
[0016] The component 3 to be treated can comprise any components that require treatment by means of an airflow, for example, moist cleaning elements. Using the example of "the component 3 to be treated comprises the drum and the cloth wrapped around the drum's circumference," the airflow is divided by the guide element into several streams distributed along the longitudinal direction of the component 3 and blown onto the drum to treat the moist cloth around the drum's circumference; the longitudinal direction of the component 3 to be treated is aligned axially with the drum.
[0017] This airflow treatment method can be used for any treatment that can be achieved through airflow, such as drying, heating, or cooling.
[0018] The air supply device can be any device capable of generating airflows and conveying these airflows into the connected guide element, for example, a fan. Furthermore, the air supply device can generate different airflows by adding additional modules to implement various airflow treatment methods. For example, when drying component 3, a heating module can be integrated into the air supply device. This heating module, using a semiconductor heating principle or other methods, generates air at a temperature above the ambient temperature and blows it onto component 3 via the guide element to perform the drying treatment.
[0019] The guide section can be any device capable of dividing the airflow and directing multiple airflows, for example, a guide plate. This guide plate is oriented perpendicular to the flow direction and is provided with multiple through-holes, so that the airflow is divided into several streams through these openings. The through-holes on the guide plate are arranged along the longitudinal direction of the component 3 to be treated in order to divide the airflow into several streams, which also run along the longitudinal direction of the component 3. This allows the airflow to be blown evenly from the air outlet opening 2 onto the component 3 to be treated.
[0020] In some embodiments, such as in Fig. 6 and Fig. 7 the guide element also includes a housing 4; wherein the air inlet opening 1 and the air outlet opening 2 are arranged on opposite sides of the housing 4 in order to form a channel for the passage of airflow with the housing 4.
[0021] The housing 4 can be designed in any shape that forms an air duct, for example as an upwardly curved arc shape, according to the design requirements of the guide element for the self-driving robot.
[0022] The housing 4 forms a channel for the airflow between the air inlet opening 1 and the air outlet opening 2, ensuring that the airflow within the guide element is restricted to the area between the air inlet opening 1 and the air outlet opening 2. This controls the direction of airflow within the guide element, directing and deflecting the airflow through the guide section between the air inlet opening 1 and the air outlet opening 2, ultimately blowing it evenly onto the component being treated.
[0023] Furthermore, the housing 4 can be designed as a hermetically sealed chamber and connected to the outside world via the air inlet opening 1 and the air outlet opening 2. The closed housing 4 forms a channel for the airflow between the air inlet opening 1 and the air outlet opening 2, ensuring that the airflow in this channel enters exclusively through the air inlet opening 1 and is expelled through the air outlet opening 2. This ensures that the airflow pressure in the channel is stable and that the entire airflow originates from the air inlet opening 1. Consequently, the airflow exiting the air outlet opening 2 maintains a stable pressure and consists entirely of the airflow supplied by the air supply device, thus ensuring the stable operation of the airflow treatment process.
[0024] In some embodiments, such as in Fig. 1, Fig. 2, Fig. 3 and Fig. 4 it further comprises a housing 4; wherein the air inlet opening 1 and the air outlet opening 2 are arranged on opposite sides of the housing, wherein the guide element has an outer surface which is attached to the self-driving robot, wherein the housing 4 is mounted on the outer surface of the guide element to form a channel with the outer surface for the passage of the airflow.
[0025] The housing 4 can be designed in any shape that forms an air duct, for example as an upwardly curved arc shape, according to the design requirements of the guide element for the self-driving robot.
[0026] Housing 4 is attached to the outer surface of the self-propelled robot using the guide element, thus eliminating the need for the guide element to have a closed housing to form an airflow channel. Instead, the channel is formed by the guide element's interaction with the robot's outer surface, reducing the guide element's footprint and simplifying its installation.
[0027] In some embodiments, the guide element further comprises a sealing strip, the sealing strip being arranged on the guide element at the point where the guide element contacts the self-propelled robot. When the guide element is attached, the sealing strip is compressed, thereby sealing the contact point between the guide element and the outer surface of the self-propelled robot when a channel is formed with the guide element installed. This prevents leaks from occurring at the contact point, through which air could escape from the formed channel, which in turn would cause an uneven airflow onto the component 3 being processed.
[0028] In some embodiments, such as in Fig. 1, Fig. 4 and Fig. 5 is the guide section located at the end of the guide element in the flow direction.
[0029] By positioning the guide element at the end of the guide section, the airflow after being directed and divided within the guide section can be blown directly onto the outer surface of the component being treated. This prevents the multiple airflows after the division and guidance, as well as the airflow after the guidance and the inner wall of the guide element, from interfering with each other, which would weaken the effect of the guidance and division and thus impair the uniformity of the airflow.
[0030] In some embodiments, such as in Fig. 1, Fig. 2, Fig. 3 and Fig. 4 the guide section is designed as a guide grid, wherein the grid lamellae 5 of the guide grid are arranged along the flow direction and form an airflow channel for the airflow passage between adjacent grid lamellae 5.
[0031] As the airflow passes through the guide grille, it enters several of the aforementioned airflow channels and is expelled from each channel, thus splitting it into multiple streams. The airflow direction within the airflow channel is restricted by the grille lamellae 5 to the direction towards the component 3 to be treated. Several grille lamellae 5 are arranged side by side, creating adjacent airflow channels whose outlets are oriented along the longitudinal axis of the component 3 to be treated. This allows the airflow to be directed into multiple streams distributed along the longitudinal axis of the component 3 and blown evenly onto the component 3 to ensure uniform treatment.
[0032] In some embodiments, such as in Fig. 4 and Fig. 5 The distance between adjacent grid lamellae 5 gradually increases along the flow direction in order to distribute the blown airflow evenly over different surface areas of the component 3 to be treated.
[0033] When the airflow comes into contact with the grid louvers 5, the grid louvers 5, arranged in the direction of airflow, collide with the airflow and block it, thereby slowing down the airflow and blowing it along both sides of the grid louvers 5 onto the component 3 to be treated. With the arrangement described in this application, the closer the grid louvers 5 are to the air inlet opening 1, the denser their arrangement; the further they are from the air inlet opening 1, the looser their arrangement.When the airflow from the air inlet opening 1 strikes the guide vane in this application, the closely spaced vane 5 near the air inlet opening 1 cause the airflow striking these vane 5 to be slowed down by the collision with the vane 5 and directed to flow to both sides of the respective vane 5, i.e., away from the air inlet opening 1. At the same time, the vane 5 further away from the air inlet opening 1 are arranged relatively more loosely, so that the airflow striking this area collides less with the vane 5 and is thus slowed down less by the vane 5.
[0034] The above-mentioned arrangement allows the air volume and velocity of the airflow to be balanced at the grille louvers 5 near the air inlet opening 1 and at the grille louvers 5 located further away from the air inlet opening 1. This ensures that the airflow is evenly divided into several streams by the respective grille louvers 5 and that the components 3 to be treated are treated uniformly.
[0035] In some embodiments, such as in Fig. 5 the grid lamellae 5 are arranged radially along the flow direction and extended to guide the airflow evenly to the surface of the component 3 to be treated.
[0036] By arranging the grid lamellae 5 in a radial distribution, several airflow channels can be formed, each consisting of adjacent grid lamellae 5, with a relatively dense inlet arrangement and a relatively open outlet arrangement. When the airflow enters the guide section, the closely spaced inlets of the airflow channels ensure that air enters each airflow channel, despite the small area of the air inlet opening 1. This directs the airflow into multiple strands along the longitudinal direction of the component 3 to be treated, thus enabling uniform distribution of the airflow onto the component 3.
[0037] In some embodiments, such as in Fig. 1 and Fig. Several grid louvers 5 are arranged radially along the longitudinal direction of the air outlet opening 2, radiating from the center point of the air inlet opening 1 as the origin, in order to guide the airflow evenly to the surface of the component 3 to be treated. It should be noted that the longitudinal direction of the air outlet opening 2 is aligned with the longitudinal direction of the component 3 to be processed.
[0038] When several grid louvers 5 are arranged radially around the center point of the air inlet opening 1, the airflow passing through the air inlet opening 1 and coming into contact with the grid louvers 5 strikes each of the grid louvers 5 at the end facing the air inlet opening 1. This directs the airflow through the air channels formed between the adjacent grid louvers 5 and blows it onto the component 3 to be treated. The radially arranged grid louvers 5 form an airflow channel with a small inlet cross-sectional area and a large outlet cross-sectional area. This allows the airflow entering the guide element through the air inlet opening 1 to be directed into the larger area of the air outlet opening 2, even if the cross-sectional area of the air inlet opening 1 is smaller than that of the air outlet opening 2.This allows for an even distribution of the airflow to all areas of the component 3 to be treated, and thus an even treatment.
[0039] In some embodiments, such as in Fig. 2, Fig. 4 and Fig. An air inlet opening 1 is provided at 5, with its end facing the end of the air outlet opening 2 in the longitudinal direction. Several grille louvers 5 are subdivided into several grille louvers 51 located near the center of the air inlet opening 1 and several grille louvers 52 located farther from the center of the air inlet opening 1. Along the longitudinal direction of the air outlet opening 2, several nearby grille louvers 51 are arranged radially around the center of the air inlet opening 1 as the origin. Several farther grille louvers 52 each have an angle of inclination to the cross-sectional area of the air outlet opening 2, with this angle of inclination gradually decreasing in the direction away from the air inlet opening 1.
[0040] The air outlet opening 2 has a first end and a second end along its longitudinal direction. The air inlet opening 1 is provided with a deviation from the centerline in the longitudinal direction of the guide section, such that the air inlet opening 1 is located on the side of the first end of the air outlet opening 2, or the air inlet opening 1 is arranged on the side of the second end of the air outlet opening 2, thereby achieving a corresponding arrangement of the air inlet opening 1 at one end in the longitudinal direction of the air outlet opening 2. The airflow generated by the supply air device is completely directed through the air inlet opening 1 between the adjacent grille louvers 5.The fewer the number of air inlet openings 1, the simpler the connection structure between the respective air inlet opening 1 and the supply air device, thus enabling a simpler coupling of the supply air device with the air inlet opening 1.
[0041] The air outlet cross-sectional area denotes the flow cross-sectional area of the air outlet opening 2; the airflow passing through the guide element is blown out of the guide element when passing the air outlet cross-sectional area.
[0042] If the air inlet opening 1 deviates from the center point of the longitudinal direction of the guide section, the two remote grille louvers 52 located furthest from the air inlet opening 1 are relatively far away from it. If all grille louvers 5 are arranged radially with the center point of the air inlet opening 1 as their origin, the airflow channel formed by the two remote grille louvers 52 is partially blocked by other remote grille louvers 52, resulting in a reduction of the air volume in the received airflow. If all remote grille louvers 52 are aligned with the center point of the air inlet opening 1, the airflow volume in the individual airflow channels can only be compensated for by adjusting the length of the remote grille louvers 52.The arrangement of the remote grid louvers 52 described above allows for an adjustment of their tilt angle within a certain range, so that experts in this field can ensure, by adjusting the tilt angle, that the airflow volume and velocity in the airflow channels formed by adjacent remote grid louvers 52 are essentially the same. This ensures that the airflow is blown uniformly onto the component 3 to be treated.
[0043] Although the guide section set up as described above can direct the airflow relatively evenly onto the component 3 to be treated, in some cases, for example, when the cross-sectional area of the air outlet opening 2 is large relative to the cross-sectional area of the air inlet opening 1, it is necessary to install a large number of grille louvers 5 and create numerous airflow channels to achieve a uniform distribution. The airflow then experiences a reduction in velocity due to the pressure loss along the airflow channels, which decreases the velocity of the airflow directed onto the component 3 to be treated and thus impairs the efficiency of the airflow treatment.
[0044] To solve the problems mentioned above, some embodiments, such as in Fig. Figure 5 shows the grid lamella 5 comprising a first nearby grid lamella 511, a first distant grid lamella 521 and a second nearby grid lamella 512, wherein the length of the second nearby grid lamella 512 is less than the length of the first nearby grid lamella 511 and the first distant grid lamella 521, wherein the second nearby grid lamella 512 is arranged between first nearby grid lamellas 511 and / or between the first nearby grid lamella 511 and the first distant grid lamella 521.
[0045] The airflow channel formed between adjacent first nearby grid lamellae 511, between first distant grid lamellae 521, and between adjacent first nearby grid lamellae 511 and first distant grid lamellae 521 is referred to as the first airflow channel. The second nearby grid lamella 512 is arranged between the aforementioned first airflow channels to form a second airflow channel together with the adjacent grid lamellae 5.Due to its shorter length, this second airflow channel includes the second nearby grid lamella 512 compared to the first nearby grid lamella 511 and the first distant grid lamella 521. Therefore, the second airflow channel formed by the second nearby grid lamella 512 and adjacent grid lamellae 5 has a shorter length in the flow direction than the first airflow channel formed by the first nearby grid lamella 511 and the first distant grid lamella 521. One or more second nearby grid lamellae 512 can be arranged within a first airflow channel to form one or more second airflow channels within the first airflow channel and adjacent grid lamellae 5. Furthermore, the arrangement of the second nearby grid lamella 512 can be omitted in the first airflow channel to form a first airflow channel that does not include the second airflow channel.
[0046] When the airflow enters the guide section and comes into contact with the grid lamellae 5, the airflow flows into the first airflow channel and the second airflow channel. By adjusting the number and position of the second nearby grid lamellae 512 in the individual first airflow channels, the airflow in the first airflow channel can be finely tuned and directed so that the guide section can direct the airflow evenly onto the component 3 to be treated.
[0047] In contrast to the arrangement of grid lamellae 5 of uniform length to form airflow channels of constant length in the flow direction, the arrangement of the first and second airflow channels described in the present application, by providing a shorter second airflow channel in the flow direction while simultaneously ensuring the guiding effect, enables a reduction in the residence time of the airflow in the airflow channels formed by the grid lamellae 5. This reduces the pressure loss caused by the airflow channels and increases the velocity of the airflow exiting the guiding section, leading to an increase in treatment efficiency.
[0048] In some embodiments, remote grid lamellae 52 also comprise a second remote grid lamella with a length that is shorter than that of the first remote grid lamella 521, wherein the second remote grid lamella is arranged between the first remote grid lamellae 521.
[0049] If the air volume and flow velocity of the airflow passing through the first airflow channel between the first remote grid louvers 521 are sufficiently high, one or more second airflow channels can be formed within this first airflow channel by arranging one or more second remote grid louvers. Through this second airflow channel, the airflow in the first airflow channel formed by the first remote grid louvers 521 can be redirected and divided, thereby blowing the airflow evenly onto the component 3 to be treated.
[0050] In the first airflow channel, one or more second nearby grille blades 512 or second distant grille blades can be arranged to reduce the flow velocity in the first airflow channel by arranging multiple second airflow channels. In the first airflow channel with a relatively low flow velocity, the arrangement of second nearby grille blades 512 or second distant grille blades can be omitted to prevent the formation of a second airflow channel by additional second nearby grille blades 512 or second distant grille blades, which would reduce the flow velocity in the first airflow channel.
[0051] The above-mentioned arrangement allows for the initial division of the airflow by establishing a few primary airflow channels; subsequently, the speed and direction of the airflow within the primary airflow channels are adjusted by arranging several secondary airflow channels.
[0052] In comparison to the arrangement of an airflow channel along the flow direction, covering the entire area from air inlet opening 1 to air outlet opening 2, the arrangement described above, by providing a shorter second airflow channel, reduces the length-dependent resistance of the airflow channel formed by the grid louvers 5. This increases the velocity of the airflow when blowing onto the component 3 to be treated, thus increasing the treatment efficiency.
[0053] The simultaneous installation of a first and second airflow channel also offers greater design flexibility in the layout of guide vanes. By adjusting the number and position of the second airflow channels, the flow velocity and volume of the airflow exiting the individual airflow channels can be regulated, allowing the airflow to be blown more evenly onto the component 3 being treated.
[0054] In some embodiments, such as in Fig. 4 and Fig. 5 The grid lamella 5 has a first end near the air inlet opening 1 and a second end near the air outlet opening 2, wherein the distance between the first end of the first nearby grid lamella 511 and the first distant grid lamella 521 and the air outlet opening 2 is greater than the distance between the first end of the second nearby grid lamella 512 and the second distant grid lamella and the air outlet opening 2 in order to split the airflow twice and direct the airflow onto the component 3 to be treated.
[0055] Due to the arrangement described above, the first end of the adjacent first near grid lamella 511 and the first far grid lamella 521 form the inlet of the first airflow channel. The second near grid lamella 512 and the first end of the second far grid lamella, together with adjacent grid lamellae 5, form the inlet of the second airflow channel. Since the first near grid lamella 511 and the first end of the first far grid lamella 521 are closer to the air inlet opening 1 than the second near grid lamella 512 and the second far grid lamella 521, this first airflow channel has an inlet that is closer to the air inlet opening 1.
[0056] In operation, the airflow passes through the air inlet opening 1 into the first and second airflow channels formed by the guide vane and is directed so that it is blown onto the component 3 to be treated. The first airflow channel has an inlet located closer to the air inlet opening 1, allowing it to receive the airflow from the air inlet opening 1 first and perform an initial division of the airflow. The airflow continues in its original direction within the first airflow channel and enters the second airflow channel, where it is directed a second time before finally being blown from the outlet of the second airflow channel onto the component 3 to be treated.
[0057] The first division of the first airflow channel allows the air to be split as soon as it exits the air inlet opening 1, so that the airflow is evenly distributed across several first airflow channels. At the same time, this ensures that the number of grille louvers 5 remains low to prevent the airflow from losing too much velocity during the first division. The second division of the second airflow channel allows the airflow already divided in the first airflow channel to be split again, dividing it into streams with equal air volume and velocity in the second division channel.By adjusting the distance between the first nearby grid lamella 511 and the second nearby grid lamella 512, which form the second airflow channel, the ratio of the airflow entering from the first airflow channel into the individual second airflow channels, as well as the speed of the airflow within the second airflow channel, can be adjusted to ensure that the airflow is blown evenly onto the component 3 to be treated.
[0058] In some embodiments, such as in Fig. 5 and Fig. 11 the individual grid lamellae 5 are arranged such that the distance between their second end and the air outlet opening 2 is always the same.
[0059] The second end of the grille lamella 5, which is equidistant from the air outlet cross-sectional area, forms multiple outlets of the first and second airflow channels, ensuring that the distance between the outlets of each first and second airflow channel and the air outlet cross-sectional area is equal. This guarantees that the airflow exiting the first and second airflow channels is discharged at positions equidistant from the component 3 being treated.
[0060] By expelling the airflow from the aforementioned first and second airflow channels at a uniform position, the mutual interference of the airflows between the individual airflow channels can be reduced, thus preventing multiple airflows from interfering with each other, which could lead to a reduction in flow velocity or even an uneven distribution of the airflow.
[0061] In some embodiments, such as in Fig. 5 and Fig. 11 is the second end of each grid lamella 5 arranged so that it extends to the air outlet cross-sectional area.
[0062] The arrangement described above allows the outlets of the first and second airflow channels to coincide with the air outlet cross-sectional areas, so that the airflow guided through the duct section can be blown directly onto the component 3 to be treated. By shortening the distance between the outlet of the first and second airflow channels and the component 3 to be treated, the airflow, after being divided into several strands distributed along the longitudinal direction of the component 3, can be blown directly onto the component 3.If the outlets of the first and second airflow channels are too far from the component 3 being processed, a portion of the already split and directed airflow will be blown from both sides of the air outlet opening 2 onto both sides of the component 3 instead of directly onto it, resulting in waste. The arrangement described above can avoid this problem, thereby improving airflow utilization and increasing processing efficiency.
[0063] Under general circumstances, the guide section formed by the combination of the nearby grid lamella 51 and the distant grid lamella 52 can direct the airflow evenly and effectively onto the component 3 to be treated. In some special cases, for example, when the ratio of the flow cross-sectional area of the air outlet opening 2 to the flow cross-sectional area of the air inlet opening 1 is relatively large, the air inlet opening 1 is located at one end of the longitudinal direction of the air outlet opening 2. Therefore, the other end of the air outlet opening 2 is far from the air inlet opening 1 in the longitudinal direction, which may prevent the airflow from reaching this area or result in very little airflow reaching it. Consequently, it is not possible to direct the airflow evenly onto the component 3 to be treated.
[0064] To solve the problems mentioned above, some embodiments, such as in the Fig. 10 to Fig. Figure 12 shows two air inlet openings 1, each arranged at one end of the longitudinal direction of the air outlet opening 2; several grid louvers 5 form two groups assigned to the two air inlet openings 1. Along the longitudinal direction of the air outlet opening 2, the grid louvers 5 of each group are distributed radially around the center point of the respective air inlet opening 1 as the origin, in order to direct the airflow uniformly to the surface of the component 3 to be treated.
[0065] The air outlet opening 2 has a first end and a second end along its longitudinal direction. If two air inlet openings 1 are arranged, the two air inlet openings 1 are distributed symmetrically along the longitudinal direction of the air outlet opening 2 with respect to the central axis of the guide section, such that one air inlet opening 1 is located at the first end of the air outlet opening 2 and the other air inlet opening 1 is located at the second end of the air outlet opening 2; in this way, the airflow supplied by the air supply device can be guided symmetrically into two groups of grille louvers 5 by means of the two air inlet openings 1.The arrangement of two air inlet openings 1 allows airflow to enter from both sides, thereby increasing the air inlet area and the volume of air drawn in. Furthermore, the airflow entering through each of the two air inlet openings 1 is guided by several grille louvers 5 on the respective side towards the central area of the air outlet opening 2. Compared to a single-sided air inlet solution, the path of the airflow along the longitudinal direction of the air outlet opening 2 is shorter in the double-sided air inlet solution, and the flow resistance during airflow passage is lower. This ensures that the airflow at both ends of the air outlet opening 2 is relatively balanced compared to the central area, which in turn enables a uniform outflow of the airflow at all positions of the air outlet opening 2 and thus ensures uniform blowing of the component 3 to be treated.Furthermore, each group of grille louvers 5 is assigned to an air inlet opening 1. Since the airflow travels a shorter distance along the longitudinal direction of the air outlet opening 2, the number of grille louvers 5 in each group can be reduced. This decreases the number of flows that need to be evenly distributed across each group of grille louvers 5 and increases the airflow between two adjacent grille louvers 5. Simultaneously, the smaller number of grille louvers 5 results in less flow resistance, which in turn leads to a higher air volume and a higher flow velocity of the air exiting the air outlet opening 2.Furthermore, the air volume and flow velocity at the various points of the air outlet opening 2 are relatively balanced, which not only increases the efficiency of the treatment of the component 3 to be processed, but also ensures a uniform distribution of the airflow on the component 3 to be processed.
[0066] At the same time, two groups of grid louvers 5 are arranged symmetrically along the longitudinal direction of the air outlet opening 2, so that the airflows emanating from the two air inlet openings 2 experience equal resistance and guidance during the respective flow guidance through the two groups of grid louvers 5; in addition, several grid louvers 5 of each group of grid louvers 5 are evenly distributed along the longitudinal direction of the air outlet opening 2 in order to further equalize the airflow volume and flow velocity at all points of the air outlet opening 2 and thus to ensure an even distribution of the airflow onto the component 3 to be treated.
[0067] In some embodiments, such as in Fig. 10 to Fig. 12 the guide section further comprises separating ribs 6, wherein the separating ribs 6 enclose a side of the air outlet cross-sectional area of the air outlet opening 2 that faces away from the several grid lamellae 5; wherein the separating ribs 6 extend along the longitudinal direction of the air outlet opening 2, wherein the distance between the separating ribs 6 and the air outlet opening 2 gradually decreases from the two ends of the separating ribs towards their center.
[0068] When the housing 4 is installed on the outer surface of the device to which the guide section is attached, the separating ribs 6 and several grid louvers 5 are arranged on the same surface of the housing 4, or the separating ribs 6 project from the outer surface of the device to which the guide section is installed in order to abut the surface on which the several grid louvers 5 are located. The arrangement of the separating ribs 6 divides the space between the housing 4 and the device to which the guide section is installed into a channel space for the airflow and an installation area for other structures. Several grid louvers 5 project vertically above the housing 4, and the separating ribs 6 project vertically at a uniform height above the housing 4. The arrangement of several grid louvers 5 divides the channel space into several airflow channels, thus ensuring the independence of each airflow channel.This results in a more even distribution of the airflow directed at the component 3 being treated.
[0069] Furthermore, the distance between the separating rib 6 and the air outlet cross-sectional area of the air outlet opening 2 gradually decreases from the two ends of the separating rib 6 towards the center. The separating rib 6 has an approximately arc-shaped structure overall, with the center projecting towards the air outlet opening 2. The separating rib 6 can restrict the airflow entering from the air inlet opening 1, directing the airflow towards the side of the multiple grille louvers 5. Additionally, the separating ribs 6 can form an airflow channel between the most widely separated grille louvers 5 of each group of grille louvers 5 and guide the airflow that has not entered the airflow channels between adjacent grille louvers 5 towards the center of the air outlet opening 2, guided by the separating ribs 6.This ensures that the airflow passing over the grille louvers 5 near the air inlet opening 1 and over the grille louvers 5 far from the air inlet opening 1 is balanced, which in turn ensures a more even air distribution at different points of the air outlet opening 2.
[0070] In some embodiments, such as in Fig. 10 to Fig. 12 the separating rib 6 comprises a connected first separating section 61 and a second separating section 62, wherein the first separating section 61 and the second separating section 62 are arranged symmetrically and each corresponds to two groups of the grid lamellae 5; wherein, at the distance between the separating rib 6 and the air outlet cross-sectional area of the air outlet opening 2, the connection point of the first separating section and second separating section is closest to the air outlet opening 2 and is located near the air outlet opening 2.
[0071] It can be seen that along the longitudinal direction of the air outlet opening 2, the separating rib 6 is divided from its central position into a first separating section 61 and a second separating section 62, each of which is assigned to the two air inlet openings 1 in order to direct the airflow entering from the respective air inlet opening 1 to the corresponding group of grille louvers 5. As an example, the figure shows the first separating section 61 on the left and the second separating section 62 on the right.
[0072] The first separating section 61 and the second separating section 62 have an identical shape and are each arranged in an arc. Both the first separating section 61 and the second separating section 62 have a connected near end and a far end facing away from each other. In the region of the first separating section 61, the distance between the first separating section 61 and the air outlet opening 2 gradually decreases from its far end to its near end. In the region of the second separating section 62, the distance between the second separating section 62 and the air outlet opening 2 also gradually decreases from its far end to its near end. This arrangement allows the airflow that does not enter between two adjacent grille louvers 5 to be guided more effectively towards the air outlet opening 2 by the first and second separating sections.Furthermore, an airflow channel forms in the central area of the corresponding air outlet opening between the separating rib 6 and the grille lamella 5 furthest from the air inlet opening 1, thereby balancing the airflow between the grille lamellae 5 near the air inlet opening 1 and those grille lamellae 5 further away. This ensures a more uniform air distribution at all points of the air outlet opening 2.
[0073] Furthermore, the first separation section 61 and the second separation section 62 are arranged symmetrically. The airflow entering through the two air inlet openings 1 experiences the same flow path at the first separation section 61 and the second separation section 62, resulting in an airflow with identical volume and velocity entering each of the two groups of grille louvers 5. Simultaneously, the two groups of grille louvers 5 are also symmetrically distributed, so that the airflow within the two groups of grille louvers 5 is also symmetrically distributed.
[0074] The connection point between the first separating section 61 and the second separating section 62 must also not be completely flush with the air outlet cross-sectional area or protrude from the air outlet opening 2. This can lead to the connection point between the first separating section 61 and the second separating section 62 at least partially obscuring the air outlet opening 2, resulting in no airflow in the central area of the air outlet opening 2, creating a so-called blind spot at the air outlet, and consequently resulting in uneven processing of the component 3 to be treated. Therefore, at the distance between the separating rib 6 and the air outlet opening 2, the connection point between the first separating section and the second separating section is located closest to the air outlet opening 2 and is situated in the vicinity of the air outlet opening 2.A gap exists between the junction of the first separating section 61 and the second separating section 62 and the air outlet cross-sectional area. This gap allows a portion of the airflow entering from the two air inlet openings 1 to flow through to the air outlet opening 2. In other words, the airflows directed from the first separating section 61 and the second separating section 62 can partially overlap in the central area of the air outlet opening 2. This ensures that an airflow is discharged in the central area of the air outlet opening 2, thus guaranteeing a uniform air distribution across the entire air outlet opening 2.
[0075] However, the gap between the connection point of the first separation section 61 and the second separation section 62 and the air outlet cross-sectional area should not be too large; if the gap is too large, the airflow exiting from the central area of the air outlet opening 2 concentrates, thereby increasing the airflow rate in the central area of the air outlet opening 2 and creating an imbalance of air volumes at the different points of the air outlet opening 2.
[0076] If two air inlet openings 1 are present, the specific arrangement of the grille louvers 5 of each group is similar to the arrangement of the grille louvers 5 described above for a single air inlet opening 1. In this case, the arrangement of the distant grille louvers 52 can be omitted. The grille louvers 5 can comprise only the first nearby grille louvers 511 and the second nearby grille louvers 512 mentioned above, wherein the first nearby grille louvers 511 and the second nearby grille louvers 512 are arranged alternately to form an airflow channel between adjacent first nearby grille louvers 511, which serves as the first airflow channel mentioned above. The second nearby grille louver 512 is arranged between the first airflow channels mentioned above to form a second airflow channel together with the adjacent grille louvers 5.The arrangement and arrangement principle of the first nearby grid lamella 511 and the second nearby grid lamella 512 have already been explained above and will not be repeated here.
[0077] In some embodiments, such as in Fig. 10 to Fig. 12 The housing 4 is provided with an expansion section 41 extending outwards from the air outlet opening 2, wherein a snap-in section 42 is provided on the expansion section 41, wherein the snap-in section 42 is suitable for being snapped into a mounting element connected to the component 3 to be treated in order to maintain the distance between the air outlet opening 2 and the component 3 to be treated.
[0078] The air outlet opening 2 is directed outwards relative to the housing 4 itself, with the central region of the housing 4 defined as the inside and the edge of the housing as the outside. The direction from the central region of the housing 4 to the edge is referred to as inside-to-outside. The expansion section 41 protrudes from the air outlet opening 2 and extends outwards. The length of the expansion section 41 is less than or equal to the length of the air outlet opening 2 to ensure that the latching section 42 provides sufficient clearance and latching strength while minimizing the blockage caused by the air outlet opening 2.
[0079] The mounting element connected to the component 3 to be processed is defined as any component that can be directly or indirectly connected to the component 3 to be processed, for example, a cleaning cover. At least part of the mounting element can be inserted into the space between the air outlet opening 2 and the component 3 to be processed in order to wedge itself against the snap-in section 42. Since the relative position of the mounting element to the component 3 to be processed is fixed, the snap-in section 42 engages the mounting element, creating a secure connection to ensure the relative position of the snap-in section 42 to the mounting element.This ensures a more secure relative position of the locking section 42 to the component 3 being treated, which in turn guarantees the relative position of the air outlet opening 2 to the component 3 and thus effectively prevents displacement of the component 3 during treatment. For example, the torsional force or spring force of the lateral water line can cause the cleaning element to slip slightly when the cleaning brush roller is placed on the base station. This results in the airflow exiting the air outlet opening 2 not being optimally directed at the component 3 being treated, thereby impairing the effectiveness of the airflow from the air outlet opening 2.
[0080] In some embodiments, the snap-in section 42 is suitable for a positive-locking connection with the adaptation section located on the mounting element, wherein several snap-in sections 42 are provided, wherein the multiple snap-in sections 42 are arranged at a distance from each other along the longitudinal direction of the air outlet opening 2; wherein expansion sections 41 and adaptation sections are arranged at a distance from each other, so that the airflow exiting the air outlet opening 2 can flow through the space between the expansion section 41 and the adaptation section in the direction of the multiple snap-in sections 42 and is then guided through the spaces between the multiple snap-in sections 42 to the component 3 to be treated.
[0081] Since the snap-in section 42 is located between the air outlet opening 2 and the component 3 to be treated, it obstructs the airflow exiting the air outlet opening 2 and thus affects the volume of air directed to the component 3, which in turn impairs the treatment efficiency of the component 3. By arranging multiple snap-in sections 42 and maintaining a distance between each pair of adjacent snap-in sections 42, forming an airflow channel, the airflow can be directed more effectively to the component 3. Multiple snap-in sections 42 can simultaneously divide the airflow, and multiple snap-in sections 42 are positioned closer to the component 3. This dividing effect of the multiple snap-in sections 42 allows the airflow to be blown more evenly onto the component 3.Furthermore, both the nearby grid lamella 51 and the distant grid lamella 52 have an angle of inclination relative to the air outlet cross-sectional area, so that the airflow exiting the air outlet opening 2 is not completely perpendicular to the air outlet cross-sectional area, but rather at an angle to it. By arranging several snap-in sections 42 directly opposite the component 3 to be treated, the airflow can be further divided and directed so that it is perpendicular to the component 3. This prevents excessive concentration of wind force in the center, and the airflow can act more evenly on all areas of the component 3, thus enabling uniform treatment.
[0082] In some embodiments, an additional locking section 42 can be provided in each of the two locking sections 42 located at the ends in the longitudinal direction of the extension section 41. Since the extension segment 41 is designed as a cantilever, the clamping force at both ends in the longitudinal direction is relatively weaker. By additionally adding the locking section 42, the clamping force at both ends in the longitudinal direction can be improved, thereby ensuring a better relative position of the locking section 42 to the component 3 being treated.
[0083] In some embodiments, each of the locking sections 42 comprises a protruding locking lug 421 arranged on the extension section 41, wherein each locking lug 421 has a locking surface oriented towards the air outlet opening 2, the locking surface being arranged at an angle so that the distance between the locking surface and the air outlet opening 2 gradually increases in the direction of the protrusion.
[0084] The shape and dimensions of the multiple snap-in lugs 421 are uniform, thus preventing local shrinkage during the manufacture of the housing 4 that could impair the overall strength of the housing 4. The adaptation section on the mounting element is designed as an adaptation arm 31, which is arcuate and has two arcuate surfaces. At least a portion of the adaptation arm 31 extends into the space between the air outlet opening 2 and the component 3 to be treated, such that the two arcuate surfaces face the component 3 and the air outlet opening 2, respectively. Several snap-in sections 42 are engaged on the end section of the adaptation arm 31 and are arranged on the side of the arcuate surface of the adaptation arm 31 facing the component 3.Furthermore, the engagement surfaces of the multiple locking lugs 421 are each inclined, specifically towards the side closer to the component 3 being treated. When assembling the guide element with the component 3 being treated, the maximum distance between the upper ends of the engagement surfaces in their projection direction and the air outlet opening 2 facilitates easier engagement on the side of the adapting arm 31 facing the component 3 being treated. The guidance provided by the multiple engagement surfaces allows the multiple locking lugs 421 to be inserted more smoothly into the side of the adapting arm 31 facing the component 3 being treated, making the assembly process less strenuous and more user-friendly.
[0085] In some embodiments, the self-driving robot includes a water tank assembly. As in Fig. 8 and Fig. The water tank assembly comprises a storage chamber. The guide element is arranged on the circumferential side of the storage chamber 71, so that the airflow conveyed to the component 3 to be treated can at least partially flow through the external environment of the storage chamber 71.
[0086] The storage chamber 71 is designed as a hollow chamber body, the interior of which can be used to store liquids or solids, for example, cleaning fluids or cleaning tablets. The shape and size of the storage chamber 71 are not specifically defined and can be individually adapted according to the size and dimensions of the device to be installed.
[0087] The guide element can form part of the chamber wall of the storage chamber 71, thereby positioning the guide element closer to the stored material in the storage chamber 71 and thus achieving a better effect on the stored material when the airflow passes the guide element. Alternatively, the guide element is arranged at least partially separated from the storage chamber 71 in order to form an airflow channel between the guide element and the outer wall of the storage chamber 71, through which an airflow is directed to the component 3 to be treated.
[0088] The guide element is arranged on the circumferential side of the storage chamber 71. As the airflow generated by the supply air device is directed through the guide element to the component 3 to be treated, the airflow can also flow around the outer circumference of the storage chamber 71, thus acting on both the storage chamber 71 and the stored materials within it. For example, if the storage chamber 71 contains clear water and a heating module has been added to the supply air device, resulting in a hot airflow, the hot airflow can heat the storage chamber 71 and the clear water stored within it as it flows around the outer circumference. This allows the heated clear water to be used for hot water cleaning or other applications requiring hot clear water.This arrangement makes it possible to do without additional heating modules outside storage chamber 71, thereby further simplifying the structure of the water tank assembly and simultaneously reducing costs.
[0089] In some embodiments, such as in Fig. 9 and Fig. 13 The water tank assembly further comprises a housing body 7, wherein the storage chamber is arranged on the housing body 7, wherein the guide element is attached to the outside of the housing body 7 and together with the housing body 7 forms an airflow channel, wherein an air inlet channel is arranged inside the housing body 7; wherein one side of the guide element is designed to be open to form an air outlet opening 2 which connects the airflow channel, wherein an air inlet opening 1 is arranged on the side of the guide element opposite the air outlet opening 2, wherein the air inlet opening 1 connects the air inlet channel to the airflow channel.
[0090] The guide element is attached to the outside of the housing body 7 and causes an outer wall of the housing body 7 to form a connection surface at a distance from the guide element. For example, if the guide element is attached to the bottom of the housing body 7, the underside of the housing body 7 forms the connection surface. The free ends of the individual grille lamellae 5 of the guide element all rest against the connection surface, so that the free ends of adjacent grille lamellae 5 can be closed by the connection surface, thereby creating airflow channels between the adjacent grille lamellae 5 that allow airflow to pass through.
[0091] An opening is provided on the connection surface of the housing body 7, which is connected to the air inlet opening 1. The number of openings corresponds to the number of air inlet openings 1. If one air inlet opening 1 is present, a corresponding opening is provided; if two air inlet openings 1 are present, two openings are provided accordingly. The two air inlet openings 1 are each directly connected to the two openings. The air outlet opening 2 is located at the lateral edge of the connection surface, with the distance between the guide element and the edge of the connection surface being dimensioned such that the air outlet opening 2 is formed.
[0092] The airflow enters the air inlet opening 1 in a direction perpendicular to the connection surface. Guided and divided by the grille louvers 5, it flows parallel to the connection surface and towards the air outlet opening 2. After entering the guide element, the airflow changes direction from perpendicular to the connection surface to parallel to it. This arrangement effectively reduces the dimensions of the water tank assembly in the direction perpendicular to the connection surface, thus saving space. Since, without changing the airflow direction, the air inlet opening 1 and the air outlet opening 2 are arranged sequentially along a direction perpendicular to the airflow, and a guide section is provided between the air inlet opening 1 and the air outlet opening 2, the guide section must fulfill a guiding and dividing function.The guide section therefore requires a certain length in the direction of airflow, which results in a certain distance between air inlet opening 1 and air outlet opening 2. This makes the dimensions of the main body of the water tank relatively large in the direction perpendicular to the connection surface. By changing the airflow direction so that the orientation of air inlet opening 1 and air outlet opening 2 points in opposite directions, the required size of the airflow guide structure in the direction perpendicular to the air inlet opening can be reduced.Simultaneously, after the airflow direction is changed, the air outlet opening 2 is positioned on the side of the housing body 7 that has a relatively larger dimension at the connection surface (referred to as the longitudinal side of the housing body 7). This allows the air outlet opening 2 to be better positioned along the longitudinal direction of the housing body 7 to align with the longitudinal direction of the component 3 being treated. Therefore, the size of the air outlet opening 2 can be relatively larger, resulting in a larger air outlet area. This allows for better longitudinal coverage of various areas of the component 3 being treated, making the entire water tank assembly more compact and space-saving.
[0093] In some embodiments, such as in Fig. 8 and Fig.14 two air inlet openings 1 are provided; wherein two air inlet channels are formed on the housing body 7, wherein the respective first ends of both air inlet channels are connected to the two air inlet openings 1 accordingly, wherein the respective second ends of both air inlet channels form two first connection interfaces 72, wherein the two first connection interfaces 72 are arranged on the outer surface of the housing body 7 and are arranged symmetrically on the two sides of the storage chamber 71.
[0094] Each air inlet duct has two duct inlets, one positioned at each end of the duct. The inlet at the first end of the duct is connected to the corresponding air inlet opening 1, while the inlet at the second end serves as the first connection interface 72. The first connection interface 72 is located on the outer surface of the housing body 7 to provide a connection and passage to the air supply device. The airflow generated by the air supply device can enter the corresponding air inlet ducts via the first connection interfaces 72 and is directed through the air inlet ducts to the respective air inlet openings 1.The airflow is then guided by the guiding and distributing action of the individual grid lamellae 5 and finally blown evenly from the air outlet openings 2 onto the components 3 to be treated.
[0095] Furthermore, both first connection interfaces 72 are connected to the air supply device, allowing air to flow into both air inlet channels simultaneously. When the airflow passes through the outer circumference of the storage chamber 71, the flow path within the guide element is relatively shorter compared to a one-sided air supply arrangement, resulting in lower flow losses. This leads to an improved effect on the storage chamber 71 and the stored materials within it. For example, the air supply device generates a hot airflow that is directed into the individual air inlet channels. The airflows entering the two air inlet openings 1 simultaneously flow towards the guide elements. As the airflow flows along the plane of the connection surface, the airflows from both sides move towards the center simultaneously. The flow path of the airflow along the plane of the connection surface is shorter, resulting in lower heat loss.Therefore, the heating effect on the stored goods in storage chamber 71 can be improved.
[0096] In some embodiments, it is provided that the water tank assembly is positioned with the guide element at the bottom of the storage chamber 71 during normal use.
[0097] The guide element can be designed as a bottom protection part of the housing body 7, and in some cases, by arranging the guide element at the bottom of the storage chamber 71, the effect of the airflow through the guide element on the stored goods in the storage chamber 71 can be improved. For example, when hot air flows within a guide element, the heat of the hot air is conducted upwards, thus making the heating of the stored goods significantly more effective.
[0098] In some embodiments, the housing body 7 of the water tank assembly can be integrated with the housing of the self-propelled robot, with the guide element forming the base housing of the autonomous robot. The storage chamber 71 is detachably attached to the housing body 7 to facilitate the removal and filling of the stored items. The air inlet duct on the housing body 7 is located inside the self-propelled robot.
[0099] One end of the air inlet duct is connected to the air inlet opening 1 of the guide element, the other end is connected to an externally mounted air supply device to direct the airflow generated by the external air supply device to the guide element and to blow it evenly onto the component 3 of the self-propelled robot to be treated.
[0100] By incorporating an integrated air inlet duct, the self-propelled robot can automatically draw in the airflow when connected to an external air supply device and use this airflow to process the components 3 on the robot. Simultaneously, the integrated air inlet duct eliminates the need for a separate air duct structure connecting the external air supply device to the air inlet opening 1 of the guide element, thus reducing the space required for the air supply device.
[0101] In some embodiments, the self-driving robot provided by the present utility model is suitable for use with a base station. The base station comprises a main body, an air supply device, and a second connection interface.
[0102] The air supply device is attached to the main body of the base station and serves to generate an airflow.
[0103] The second connection interface is connected to the air supply device and is suitable for connection to the first connection interface 72 of a self-driving robot.
[0104] By using this system in combination with the aforementioned base station, the first connection interface 72 on the robot is conductively connected to the second connection interface on the base station when the self-propelled robot moves onto or near the base station. The air supply device then generates an airflow, allowing the air to flow from the second connection interface to the first connection interface 72 and enter the air inlet duct of the self-propelled robot. The airflow is then directed through the air inlet duct to the guide element of the self-propelled robot, ensuring that the airflow is blown evenly from the air outlet opening 2 onto the component 3 being processed.The airflow used to blow off the component 3 being treated is not blown directly from the base station. Instead, after connecting the first connection interface 72 to the second connection interface, it enters the air inlet duct, then passes inside the self-propelled robot, and is subsequently blown out of the self-propelled robot's air outlet opening 2. No complex airflow guidance structure is required on the main body of the base station, resulting in a comparatively simpler base station structure. Furthermore, the air outlet opening 2 is located on the self-propelled robot, allowing it to be positioned closer to the component 3 being treated, thus increasing the blow-off efficiency.In addition, the airflow is distributed evenly onto the component 3 to be treated by a guiding element, so that the airflow can treat the component 3 to be treated evenly and the treatment efficiency is increased.
[0105] The main body of the base station can be designed in any shape that allows for easy placement by the self-propelled robot. The main body of the base station has at least one storage platform or a receiving chamber for placement by the self-propelled robot. The components to be processed by the self-propelled robot can be cleaned and / or the self-propelled robot can be recharged via the main body of the base station.
[0106] The air supply unit can be installed inside the main body of the base station, resulting in a more compact structure. Alternatively, the air supply unit can be detachably mounted on one side of the main body of the base station for easier maintenance. The air supply unit can be any device capable of generating airflows and conveying these airflows to the connected guide element, such as a fan or pump. Furthermore, the air supply unit can be configured to generate different airflows by adding additional modules, enabling various airflow treatment methods.For example, when drying the component 3 to be treated, a heating module can be integrated into the supply air device, which generates an airflow with a temperature above the ambient temperature using the semiconductor heating principle or other methods, conveys it into the guide element after it has been inserted into the air inlet channel of the self-propelled robot and blows this airflow over the guide element onto the component 3 to be treated in order to carry out the drying treatment.
[0107] The number of second connection interfaces corresponds to the number of first connection interfaces (72). If one first connection interface (72) is provided, a second connection interface is also provided; if two first connection interfaces (72) are provided, two second connection interfaces are provided accordingly. When the self-propelled robot docks with the base station, the first connection interface (72) and the second connection interface automatically connect to each other to ensure that the airflow generated by the air supply device is directed into the self-propelled robot.
[0108] In some embodiments, sealing rings are attached to the first connection interface 72 and / or the second connection interface. When connecting the first connection interface 72 to the second connection interface, the first connection interface 72 is attached to the outside of the second connection interface and presses the sealing ring located between the first connection interface 72 and the second connection interface; or the second connection interface is attached to the outside of the first connection interface 72 and presses the sealing ring between the first connection interface 72 and the second connection interface; alternatively, sealing rings are attached to the connection ends of the first connection interface 72 and the second connection interface, which are pressed together when the two come close to each other to ensure a seal at the connection point.To prevent airflow from escaping at the connection point between the first connection interface 72 and the second connection interface, which leads to significant air losses, impairs the volume of air exiting the air outlet 2, and thus negatively affects the treatment efficiency of the component 3 being treated. In summary, the self-propelled robot presented in this utility model is capable of dividing and directing the airflow entering through the air inlet 1 by means of an internal guide section when connected to an external air supply device, so that the airflow is blown evenly onto the component 3 being treated. The guide section is designed to be radially distributed and is arranged as near-proximal and distant grid lamellae 51.This allows the airflow from the air inlet opening 1, even if this air inlet opening 1 deviates from the center point in the longitudinal direction of the guide section, to still be partially deflected by the guide section and blown evenly onto the component 3 to be treated. Alternatively, the guide section is designed by arranging two groups of grid louvers 5 such that the airflows entering from two symmetrically arranged air inlet openings 1 can be blown evenly onto the component 3 to be treated by the division and guidance of the two groups of grid louvers 5. Simultaneously, the arrangement of the first nearby grid louver 511, the second nearby grid louver 512, and / or the first distant grid louver 521 and the second distant grid louver 521 forms a first airflow channel and a second airflow channel to reduce the velocity of airflow loss as it passes through the guide section.This results in a higher speed of the airflow when blowing onto the component 3 to be treated, which in turn increases the efficiency of the airflow treatment.
