Embodiments of the present invention

[0022] To enable those skilled in the art to more clearly understand this disclosure, the technical solutions in the embodiments of this disclosure 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 disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0023] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this disclosure. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this disclosure provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0024] According to a first aspect of this disclosure, a decorative cover mounting structure is provided for use in cleaning equipment, which makes the decorative cover stable to install and easy to disassemble, and at a lower cost.

[0025] Please refer to Figures 1, 2, and 3, which show the overall structural diagram, exploded view, and bottom view of the decorative cover mounting structure 1100, respectively. The decorative cover mounting structure 1100 includes a decorative cover 200 and a mounting component 110a for mounting the decorative cover 200. The decorative cover 200 and the mounting component 110a are respectively provided with a first fastener 1111 and a second fastener 1112. The decorative cover 200 is detachably connected to the mounting component 110a via a snap-fit ​​structure 1110 formed by the first fastener 1111 and the second fastener 1112. The mounting component 110a has an opening 111 for exposing the dust box of the cleaning equipment, and the decorative cover 200, after being mounted on the mounting component 110a, can cover this opening 111 to maintain the aesthetics of the cleaning equipment 1000. Furthermore, the snap-fit ​​structure 1110 also makes the decorative cover 200 easy to remove. Compared to related technologies that use magnetic attraction to fix the decorative cover 200, the decorative cover mounting structure 1100 uses a snap-fit ​​structure 1110. The snap-fit ​​structure 1110 can be integrally formed with the decorative cover 200 and the mounting component 110a, resulting in lower costs. Furthermore, the snap-fit ​​connection is more stable, and the decorative cover 200 can only be removed in the snap-fit ​​direction of the snap-fit ​​210, preventing the decorative cover 200 from being accidentally detached due to contact.

[0026] When not assembled, the decorative cover 200 with the first fastener 1111 and the mounting component 110a with the second fastener 1112 are completely separate, as shown in Figure 2. Consumers can clean the dust box through the opening 111 on the mounting component 110a, or remove the entire dust box for cleaning through the opening 111. The mounting component 110a can be designed specifically for mounting the decorative cover 200, or it can be a component of the cleaning equipment itself; this disclosure does not impose any limitations.

[0027] The decorative cover 200 should at least cover the opening 111 on the outer side of the mounting component 110a. In some embodiments, to improve the aesthetics and facilitate consumer operation, the shape of the decorative cover 200 is the same as the outline of the mounting component 110a, and the decorative cover 200 is a one-piece structure that completely covers the outer side of the mounting component 110a. Of course, in other embodiments, the decorative cover 200 can also be designed as a split structure; for example, the decorative cover 200 includes multiple sub-plates, all of which are detachably connected to the mounting component 110a via a snap-fit ​​structure 1110. This allows consumers to change the color and / or material of the sub-plates according to their personal preferences, achieving different styles.

[0028] The related technologies disclose various structural forms of the snap-fit ​​structure 1110, all of which can be applied to this disclosure. Therefore, this disclosure does not limit the specific structural form of the snap-fit ​​structure 1110.

[0029] Referring to Figures 4, 5, and 6, in some embodiments, the first fastener 1111 is a snap fastener 210 protruding from the inner side of the decorative cover plate 200 to ensure that the outer side of the decorative cover plate 200 is a flat plane. Correspondingly, the second fastener 1112 is a snap groove 112 recessed into the inner side of the mounting component 110a. The groove wall of the snap groove 112 is provided with a snap position 1121. The snap fastener 210 extends into the snap groove 112 from the opening of the snap groove 112 and engages with the snap position 1121. By setting the snap position 1121 in the snap groove 112, since the snap groove 112 is not in communication with the space below the mounting component 110a, and water on the surface of the mounting component 110a or the decorative cover plate 200 cannot pass through the snap groove 112, the snap structure 1110 has a waterproof effect.

[0030] In some embodiments, both the decorative cover 200 and the mounting component 110a are made of plastic. Several snap fasteners 210 are integrally molded with the body of the decorative cover 200 via injection molding. The mounting component 110a is also injection molded, and a recessed snap groove 112 is directly formed during injection molding. When the decorative cover 200 and the mounting component 110a are fastened together, the decorative cover 200 will move rapidly and touch the mounting component 110a. This rapid impact can generate a loud noise and may also damage the decorative cover 200 and the mounting component 110a. Especially when both the decorative cover 200 and the mounting component 110a are plastic parts, cracks may appear on them after prolonged use. Therefore, in some embodiments, two or more flexible elements are provided on the contact surface between the decorative cover 200 and the mounting component 110a, spaced apart circumferentially. The flexible elements can be made of flexible materials such as sponge pads, rubber pads, or silicone pads, and are attached to the inner surface of the decorative cover 200 and / or the outer surface of the mounting component 110a.

[0031] To ensure stable installation of the decorative cover plate 200, the number of snap-fit ​​structures 1110 should be more than two, that is, the number of snap-fit ​​structures 210 and snap-fit ​​grooves 112 should both be more than two; the two or more snap-fit ​​structures 210 and the two or more snap-fit ​​grooves 112 are distributed at intervals. Each snap-fit ​​structure 210 and each snap-fit ​​groove 112 can be distributed at intervals along the same circumference or distributed on different circumferences, and this disclosure does not impose any restrictions. In some embodiments, the number of snap-fit ​​structures 1110 is 4, and the four snap-fit ​​structures 1110 are evenly distributed along the same circumference, with the included angle between each pair being 90°. In other embodiments, please refer to Figure 3, both the mounting component 110a and the decorative cover plate 200 are circular; the number of snap-fit ​​structures 1110 is 3, and the three snap-fit ​​structures 1110 are symmetrically distributed along the central axis of the decorative cover plate 200; one snap-fit ​​structure 1110 is located on the central axis, and the remaining two snap-fit ​​structures 1110 are symmetrically distributed with respect to the central axis.

[0032] The specific location of the latch 210 also needs to be considered to avoid interference with surrounding components. In the embodiments shown in Figures 3 and 7, the mounting component 110a has a button 130. Therefore, the latch structure 1110 near the button 130 should be located outside the button 130, so that the latch structure 1110 is closer to the edge of the decorative cover 200 and the mounting component 110a than other latch structures 1110. In some embodiments, the groove wall of the latch groove 112 near the button 130 has a through-hole 1122 connecting to the external environment; if there is water in the latch groove 112, the water will flow to the outside through the through-hole 1122 and will not enter the interior of the mounting component 110a.

[0033] The specific structural form and parameters of the snap-fit ​​structure 1110, specifically the snap-fit ​​210, affect the force required for the snap-fit ​​structure 1110 to engage and disengage, as well as the tactile feedback to the operator. For the cleaning equipment 1000, since it moves continuously during operation and may come into contact with walls, tables, or other objects, the snap-fit ​​structure 1110 must be securely connected and provide clear tactile feedback to the consumer during installation, ensuring that the consumer is fully aware that the decorative cover 200 has been installed correctly.

[0034] Therefore, referring to Figures 4 and 5, in some embodiments, at least one snap fastener 210 adopts the following structure: the snap fastener 210 includes a root portion 211, a curved portion 212, and a snap fastener 213 connected in sequence, with the snap fastener 213 located on the side of the curved portion 212 facing the snap fastener 1121. The snap fastener 213 is spaced apart from the root portion 211, and the gap between them forms a retraction space for the snap fastener 213. The snap fastener 1121 of the mounting component 110a can be a protrusion structure provided on the groove wall, a recessed area provided on the groove wall, or a combination of a protrusion structure and a recessed area forming the snap fastener 1121. In some embodiments, the contact positions of the snap fastener 213 and the snap fastener 1121 are both set as curved surfaces to reduce the jerking sensation when the snap fastener structure 1110 is engaged and disengaged.

[0035] During the engagement and disengagement of the buckle 210 and the buckle groove 112, the bent portion 212 undergoes a certain degree of bending deformation. The elastic force of the bent portion 212 acts on the buckle portion 213 and is transmitted to the human hand through the decorative cover plate 200 to generate tactile feedback. The shape of the bent portion 212 can be an arc, an elliptical arc, a spiral segment, etc., and this disclosure does not impose any limitations. Referring to Figure 5, in some embodiments, the bending contour line of the bent portion 212 is an arc, and the diameter of the arc is the dimension b of the back space. That is, the contour line of the bent portion 212 is a semi-circular arc and a tangent connecting the two ends of the semi-circular arc; when the tangent is set to be parallel to the groove wall of the buckle groove 112, the direction of the buckle portion 213 abutting against the buckle position 1121 is perpendicular to the buckle groove 112 to ensure the stable connection of the buckle structure 1110.

[0036] In terms of usability, the interference between the buckle 213 and the buckle position 1121 affects the force required for the consumer to install or remove the decorative cover 200; the retraction space of the buckle 213 and the thickness and extension length of the bent portion 212 both affect the strength of the buckle 210, thus affecting the consumer's tactile feedback. Referring to Figure 5, in some embodiments, the relevant parameters of the buckle structure 1110 are as follows: the interference a between the buckle 213 and the buckle position 1121 is 0.5~1.5mm, for example, 0.5mm, 0.7mm, 0.95mm, 1mm, 1.25mm, 1.45mm, etc. The retraction space b of the buckle 213 is 3~4mm, for example, 3mm, 3.25mm, 3.45mm, 3.5mm, 3.65mm, 3.85mm, 3.95mm, etc. The thickness c at the location of the buckle 213 is 2.5~3.5mm, for example, 2.5mm, 2.7mm, 2.85mm, 3mm, 3.2mm, 3.45mm, etc. The thickness d of the bent portion 212 is 1~2mm, for example, 1mm, 1.25mm, 1.45mm, 1.5mm, 1.6mm, 1.85mm, etc. The extension length e of the bent portion 212 in the engagement direction of the buckle 210 and the buckle groove 112 is 6~7mm, for example, 6mm, 6.2mm, 6.35mm, 6.45mm, 6.5mm, 6.6mm, 6.85mm, etc. The extension length e is also the distance between the top surface of the buckle 213 and the lower quadrant point of the bent portion 212 in the engagement direction of the buckle 210 and the buckle groove 112.

[0037] The root 211 of the snap fastener 210 connects to the body of the decorative cover plate 200, affecting the overall fatigue strength and durability of the snap fastener 210. Referring to Figure 5, in some embodiments, the cross-sectional dimension of the root 211 decreases from the body of the decorative cover plate 200 to the bend 212. In some embodiments, the cross-sectional dimension of the root 211 may gradually decrease along the protruding direction of the snap fastener 210, and the closer the root 211 is to the body of the decorative cover plate 200, the larger its size; a larger root 211 results in greater strength, thus preventing the snap fastener 210 from breaking at the root 211.

[0038] In practical use, all the buckles 210 on the decorative cover plate 200 can be configured with the above-described structure, or only some of the buckles 210 can be configured with the above-described structure; this disclosure does not impose any limitations. Referring to Figure 8, the decorative cover plate 200 of the embodiment shown in Figure 8 includes two types of buckles 210. One type of buckle 210 adopts the structure described above, including a root portion 211, a curved portion 212, and a latching portion 213; for ease of description, it is referred to as the first buckle 210a below. The other type of buckle 210 only includes a root portion 211 and a latching portion 213 connected in sequence, without a curved portion 212; for ease of description, it is referred to as the second buckle 210b below. In the second buckle 210b, the latching portion 213 is located on the side of the root portion 211 facing the latching position 1121. The second buckle 210b only serves to constrain the decorative cover plate 200 and does not provide tactile feedback when fastened. During installation, the second buckle 210b should first be inserted into the corresponding buckle groove 112, and then the decorative cover plate 200 should be pressed down so that the first buckle 210a is inserted into the corresponding buckle groove 112.

[0039] Since the second snap fastener 210b has no curved portion 212, its overall volume is smaller than that of the first snap fastener 210a, which has a curved portion 212, making it suitable for placement in areas with limited space. For example, in the decorative cover mounting structure 1100 of the embodiment shown in Figures 7 and 8, both the mounting component 110a and the decorative cover 200 are circular, and the number of snap fastener structures 1110 is three; one snap fastener structure 1110 is located on the central axis, and the remaining two snap fastener structures 1110 are symmetrically distributed with respect to the central axis. The mounting component 110a has a button 130, and the snap fastener structure 1110 located on the central axis is close to the button 130 and located outside the button 130; the snap fastener 210 of this snap fastener structure 1110 uses the second snap fastener 210b, which has a smaller volume, and the corresponding snap groove 112 also has a smaller volume. The snap fasteners 210 of the other two snap fastener structures 1110 are both first snap fasteners 210a. The first buckle 210a is positioned closer to the center of the decorative cover 200 than the second buckle 210b.

[0040] Please refer to Figure 9. A second aspect of this disclosure provides a cleaning device 1000. The cleaning device 1000 can be a robotic vacuum cleaner or a floor scrubber. The cleaning device 1000 includes a device body 100, a dustbin 300, and a decorative cover mounting structure 1100 as described in any of the first aspects above. The upper cover 110 of the device body 100 constitutes the mounting component 110a in the decorative cover mounting structure 1100. Referring to Figure 10, the dustbin 300 is disposed in the device body 100 and exposed through the opening 111 of the mounting component 110a. After the decorative cover 200 is installed on the upper cover 110, the dustbin 300 is concealed, as shown in Figure 9, making the cleaning device 1000 more aesthetically pleasing. When the decorative cover 200 is removed, the dustbin 300 is exposed through the opening 111 of the upper cover 110, as shown in Figure 10, allowing the consumer to clean the dustbin 300.

[0041] In some embodiments, the dustbin 300 is detachably connected to the device body 100, and the entire dustbin 300 can be removed from the device body 100, allowing the consumer to clean the interior of the dustbin 300 and replace the filter. In other embodiments, the dustbin 300 is integrated with the device body 100; for example, the dustbin can be integrated with the top cover 110 or with the bottom cover 120 of the device body 100. If the cover and filter of the dustbin 300 are detachable, the cover and filter can be easily removed and installed through the opening 111 of the mounting component 110a. After the cover and filter are removed, the consumer can wipe the interior of the dustbin 300 through the opening 111 of the mounting component 110a.

[0042] Depending on the specific structure of the cleaning device 1000 mounted on the decorative cover plate 200, several clearance holes can be provided on the decorative cover plate 200 and the mounting component 110a. As shown in Figures 10 and 11, in some embodiments, the cleaning device 1000 is equipped with a protruding sensor module 400. The sensor module 400 can integrate electronic devices such as radar, infrared sensors, laser rangefinders, and communication modules to realize functions such as obstacle recognition, obstacle avoidance, path planning, and data communication. Correspondingly, both the decorative cover plate 200 and the mounting component 110a are provided with first clearance holes 10 for avoiding the sensor module 400. The sensor module 400 protrudes outward through the first clearance holes 10 of the decorative cover plate 200 and the mounting component 110a. In some embodiments, the mounting component 110a is provided with a plurality of buttons 130, and the corresponding position of the decorative cover plate 200 needs to be provided with a second clearance hole 20 that matches the shape of the button 130. The button 130 extends into the second clearance hole 20 or is exposed through the second clearance hole 20 to facilitate operation by the consumer.

[0043] Other components of the cleaning equipment 1000 have not been improved in this disclosure. For details, please refer to the relevant disclosures in related technologies. They will not be elaborated here.
