Removable assembly of a garbage guiding channel and a cleaning device for a cleaning appliance

Abstract

The application discloses a detachable combined garbage guiding channel for a cleaning appliance, which comprises a shovel strip structure composed of a shovel strip support and a shovel strip body connected with the shovel strip support, and a detachable fixing assembly for fixing the shovel strip support to a shell of the cleaning appliance. A part of surfaces of the shovel strip body and the detachable fixing assembly form an integral garbage guiding arc surface. The garbage guiding channel has two or more arc surfaces with different frictional forces. The arc surface with large frictional force is more favorable for fine-particle garbage to accumulate into medium-particle garbage. The arc surface with small frictional force is more favorable for medium-particle garbage to flow rapidly in the garbage channel by means of inertia of a cleaning roller. The combined garbage guiding channel is simple in structure, reliable in fixation and convenient to disassemble.

Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a detachable and modular garbage guide channel and cleaning device for cleaning appliances. Background Technology

[0002] Existing floor cleaners are generally categorized into two branches: air-jet cleaning (represented by vacuum cleaners) and water-jet cleaning (represented by roller scrubbers). However, due to the limitations of their working principle, vacuum cleaners cannot clean some stubborn debris and stains that are firmly attached to the floor. Water-jet scrubbers, on the other hand, use a motor to drive a cleaning drum that typically uses a sponge-like structure. The floor cleaner also includes a water supply system and a water tank to clean the cleaning drum, thus achieving a perfect cleaning of the floor. To clean the cleaning drum, a closed cleaning space connected to the water supply system is usually set up to clean specific sections of the drum, providing clean water for rinsing the drum before the wastewater is pumped away.

[0003] This type of floor cleaner typically features an integrated dust collector strip behind the cleaning roller, with one end contacting the ground and the other end wrapping around the cleaning roller. This facilitates the transport of debris to the dustbin under the action of the cleaning roller. The advantage of this integrated dust collector strip is that it reduces debris retention on the shovel, preventing localized debris accumulation. Currently, the integrated dust collector strips on the market are usually fixed to the housing with glue or formed into a single structure using a secondary molding technique, then forming a debris guiding channel together with the corresponding curved surface of the cleaning roller. However, because this type of integrated dust collector strip is made of a single material, the friction force experienced by fine particles in the debris guiding channel remains relatively constant, making it easy for debris to accumulate in the channel and difficult to be guided into the dustbin. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide a detachable and combinable garbage guide channel for cleaning appliances, which has two or more arc surfaces with different friction forces in the garbage guide channel. The section with higher friction force is more conducive to the accumulation of fine particles into medium particles, while the section with lower friction force is more conducive to the rapid flow of medium particles in the garbage channel by taking advantage of the inertia of the cleaning roller.

[0057] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0058] This invention provides a detachable and modular waste guiding channel for cleaning appliances. The waste guiding channel has two or more arc surfaces with different friction forces. The section with higher friction force is more conducive to the accumulation of fine particles into medium particles, while the section with lower friction force is more conducive to the rapid flow of medium particles in the waste channel by utilizing the inertia of the cleaning roller. The modular waste guiding channel has a simple, fixed, and reliable structure, and is also easy to disassemble.

[0059] Example 1:

[0060] like Figures 1-4 As shown, a detachable and modular waste guiding channel for a cleaning appliance includes a housing 1, a shovel 2, and a detachable fixing assembly. The shovel 2 includes a shovel bracket 21 and a shovel body 20. The detachable fixing assembly fixes the shovel bracket to the housing of the cleaning appliance. The detachable fixing assembly includes a fixing member 3, a pressure plate 4, a bolt 5, and a double-sided guide strip 6. The double-sided guide strip includes a double-sided guide strip body 60 and a double-sided guide strip bracket 61. The surfaces of the shovel body and the double-sided guide strip body facing the cleaning roller together form a complete waste guiding arc surface.

[0061] like Figures 3-4As shown, the double-sided guide strip body 60 covers the surface of the double-sided guide strip bracket 61. The double-sided guide strip bracket 61 is slidably connected to the sliding groove 31 on the top surface of the fixing member 3. The supporting inclined surface 613 of the double-sided guide strip bracket 61 and the limiting inclined surface 32 on the side of the fixing member 3 can slide and abut against each other. To achieve a fixed connection between the pressure plate 4 and the fixing member 3, the fixing member 3 is provided with a threaded hole, and the pressure plate 4 is provided with a corresponding chamfered through hole. During assembly, the chamfered through hole of the pressure plate 4 is aligned with the screw hole of the fixing member 3, and then the bolt 5 is passed through the above-mentioned through hole and locked with the threaded hole. After locking, due to the design of the sliding groove 31 and the limiting inclined surface 32, the fixing member 3 and the double-sided guide strip 6 can slide together. The double-sided guide strip body 60 has a downward-facing abutment surface 602 at one end. The shovel body 20 covers the surface of the shovel support 21. The upper part of the shovel body has a shovel body abutment surface 202 perpendicular to the surface of the cleaning roller. The abutment surface 602 and the shovel body abutment surface 202 can slide together. The end of the double-sided guide strip body 60 corresponding to the arc surface of the cleaning roller also has an arc surface adapted to the roller brush assembly. The intersection of the arc surface of the double-sided guide strip body 60 corresponding to the cleaning roller and the arc surface adapted to the roller brush assembly is the diversion tip 601. Medium-sized particles of waste, after passing the diversion tip 601 under the action of the cleaning roller, will be brushed into the arc surface of the roller brush by the oncoming roller brush assembly. Finally, under the action of the momentum provided by the roller brush assembly, they fall into the waste box in a parabolic shape along the arc surface of the roller brush.

[0062] The shovel bar bracket 21 has a first fixing part 211 and a second fixing part 212 opposite to the first fixing part. The first fixing part 211 is a right-angled protrusion that cooperates with the limiting part 41 of the pressure plate 4. The second fixing part 212 slidably abuts against the concave surface next to the contact surface 602 of the double-sided guide bar body. The lower part of the first fixing part 211 has a limiting notch 216, which cooperates with the contact step 42 of the pressure plate 4 for fixation. The shovel bar bracket below the limiting notch 216 also has an outwardly protruding first limiting protrusion 217, which is right-angled and cooperates with the right-angled groove of the concave part of the contact step 42 of the pressure plate 4. When both the double-sided guide bar and the pressure plate are connected to the fixing member, the end face formed by the multi-faceted combination of the lower end of the double-sided guide bar, the limiting part 41 of the pressure plate 4, and the contact step 42 of the pressure plate 4 together form a sliding groove that allows the shovel bar bracket to slide in both directions.

[0063] In this embodiment, no screw hole is provided on the first limiting protrusion 217, but a slot can be provided on the pressure plate. The first limiting protrusion 217 is inserted into the slot to realize the movable connection between the shovel bar and the pressure plate.

[0064] If necessary, the shovel bar bracket is also provided with an extension 215, which can enhance the strength of the shovel bar body 20.

[0065] like Figure 4As shown, in order to achieve a push-pull sliding connection between the shovel bar 2, the double-sided guide bar 6, and the pressure plate 4, the shovel bar bracket 21 is provided with a limiting notch 216, a first limiting part 211, and a second limiting part 212. Correspondingly, the pressure plate 4 is provided with an abutting step 42 that cooperates with the limiting notch 216. The sliding groove 31 is provided with a limiting inclined surface 32 that cooperates with the third limiting part 213 at one of its extended ends near the shovel bar 2. The pressure plate 4 is provided with a limiting step 41 that cooperates with the first limiting part 211. The pressure plate 4 is also provided with an abutting step 42 that cooperates with the limiting notch 216. The first limiting part 211 and the second limiting part 212 are respectively provided on two opposite surfaces of the shovel bar support 21. The first limiting part 211 is set in a right angle shape, and the second limiting part is set in an obtuse angle shape. When the arc surface of the shovel bar body 20 is impacted by large particles of garbage, the obtuse angle design of the second limiting part makes it easier to absorb the impact force and smoothly transmit it to the shovel bar support 21. The right angle design of the first limiting part 211 makes it easier to directly transmit the impact force transmitted from the shovel bar body to the pressure plate 4. Since both the shovel bar support 21 and the pressure plate 4 are made of hard materials, the right angle design can withstand greater impact force.

[0066] In this embodiment, to better coordinate the shovel 2 and the pressure plate 4 for a tighter fit, the limiting notch 216 is hook-shaped, with a first inclined surface cut out at the tip of the hook and a right angle at the root. The corresponding end face of the abutting step 42 also has a second inclined surface, with the root of the hook of the abutting step 42 also being a right angle. When the limiting notch 216 and the abutting step 42 are fitted together, the first inclined surface fits tightly with the second inclined surface. When the inclined surfaces fit together, the fit is tighter than that of two right angles. The above design of the limiting structures of the shovel makes the fit between the shovel and the pressure plate tighter. While enabling the shovel to be detachable, the curved surfaces that come into contact between the shovel and the pressure plate are more conducive to absorbing the impact when the curved side of the shovel is impacted, by utilizing the support of the small areas in the curved surfaces that come into contact.

[0067] To achieve a sliding track (not shown in the figure) formed between the pressure plate 4, the double-sided guide strip 6, and the shovel strip 2, extending counterclockwise from the recessed right-angle groove at the bottom of the abutting step 42 to the abutting surface 602 of the double-sided guide strip 6 along the outer surface of the pressure plate 4 and the double-sided guide strip 6, allowing the shovel strip 2 to slide in a pull-out manner, the fixing member 3 is provided with a threaded hole, and the pressure plate 4 is provided with a corresponding chamfered through hole. During assembly, the chamfered through hole of the pressure plate 4 is aligned with the screw hole of the fixing member 3, and then the bolt 5 is passed through the above-mentioned through hole and locked with the threaded hole.

[0068] like Figure 1As shown, the slide (not shown in the figure) extends along the length of the cleaning appliance. The slide has an opening on the side of the cleaning appliance, or an opening is formed on each of the two sides along its length after the fixing member 3 and the pressure plate 4 are connected and fixed. When assembling the scraper 2, the scraper bracket 21 is slid into the slide from the opening on the side of the cleaning appliance, thus achieving a detachable sliding connection of the scraper 2. For aesthetic purposes, a decorative panel 25 is provided on the side of the cleaning appliance to cover the slide. Optionally, the decorative panel 25 is fixedly connected to one end of the scraper 2. When replacing the scraper 2, the decorative panel 25 can be directly pried out, and the entire scraper 2 can be pulled out by pulling it outwards. Optionally, the decorative panel 25 only covers the installed scraper 2 on the side surface of the cleaning appliance. When replacing the scraper 2, the decorative panel 25 is first removed, and then the entire scraper 2 is pulled out from the side. Optionally, the decorative panel 25 is fixed to one end of the double-sided guide strip 6. When replacing the double-sided guide strip 6, the decorative panel 25 can be pried off directly, and the entire double-sided guide strip 6 can be pulled out by pulling it outwards. Optionally, the decorative panel 25 only covers the side surface of the installed double-sided guide strip 6 on the cleaning appliance. When replacing the double-sided guide strip 6, first remove the decorative panel 25, and then pull out the entire double-sided guide strip 6 from the side.

[0069] In this embodiment, the shovel body 20, the double-sided guide strip body 60, the two arc surfaces opposite to the cleaning roller, and the corresponding surface of the cleaning roller together form a complete garbage guiding channel. The shovel 2 includes two parts: the shovel support 21 and the shovel body 20. Since the shovel support 21 needs to achieve a movable connection with the pressure plate 4 and provide a certain support force for the shovel body 20, the shovel support 21 is designed to be made of rigid material. The shovel body 20, as a garbage guiding mechanism, directly contacts the ground to remove garbage. In order to improve its friction with the ground and achieve a better cleaning effect, the shovel body 20 is designed to be made of soft material, such as silicone.

[0070] like Figure 4 As shown, the second fixing part 23 of the shovel support 21 is also provided with an extension part 215. The shovel body extends in the direction corresponding to the extension part 215 and is provided with a shovel part 201. The shovel part is designed as a clearance surface for the cleaning appliance sponge roller, and the curvature of the shovel part is adapted to the arc surface of the sponge roller placed in the housing 1.

[0071] In this embodiment, the end of the shovel support 21 connected to the shovel body 20 is further provided with a radial support surface 218 and a tangential support surface 219. When the user uses the cleaner, when large particles of waste enter the waste channel formed between the surface of the cleaning drum, the shovel 2, and the fixing member 3, the radial support surface 218 can provide greater support to the shovel body 20 in the radial direction of the cleaning drum; when large particles of waste have just been shoveled up and have not yet entered the waste channel formed between the surface of the cleaning drum, the shovel 2, and the fixing member 3, the tangential support surface 219 can provide greater support to the shovel body 20 in the tangential direction of the cleaning drum.

[0072] In the actual production process of the spade 2, a hard material spade bracket 21 is first injection molded. Then, the hard spade bracket 21 is placed into the mold cavity, and the soft material spade body 20 is injection molded on the radial support surface 218 and tangential support surface 219 of the spade bracket 21. Due to the stability issues of process parameters such as mold cavity temperature control and mold cavity pressure maintenance on the injection molding equipment, the spade body 20 often "overflows" the radial support surface 218 and tangential support surface 219 of the spade bracket 21 during mass production. As long as the "overflowing" spade body 20 does not extend to the first limiting part 211 and the third limiting part 213 of the spade bracket 21, it will not affect the fit between the spade bracket 21, the fixing part 3, and the pressure plate 4. This secondary molding design of the spade body 20 and the spade bracket 21 on the radial support surface 218 and the tangential support surface 219 can reduce the process precision requirements of the corresponding manufacturing mold and injection molding equipment, and improve the compatibility and manufacturability of the spade 2.

[0073] In this embodiment, the angle between each inclined plane and the horizontal plane is designed to be 30-60 degrees. The shovel bar 2 and the pressure plate 4, as well as the shovel bar 2 and the double-sided guide bar 6, are connected by multiple planes, which makes it easier to transmit force in the horizontal and vertical directions when the shovel bar 2 is under force, making the shovel bar more secure.

[0074] To prevent the shovel blade 2 from falling out of the slide, a limiting groove and a locking groove (not shown in the figure) are provided on the shovel blade bracket 21. Correspondingly, a protrusion (not shown in the figure) corresponding to the limiting groove and a locking slot (not shown in the figure) corresponding to the locking groove are provided in the slide. There are multiple limiting grooves on the shovel blade bracket 21 and multiple protrusions in the slide. There is one locking groove on the shovel blade bracket 21 and one locking slot in the slide. During the process of the shovel blade 2 sliding into the slide, the limiting groove slides past each protrusion in turn until each limiting groove and the corresponding protrusion completely overlap. This can remind the user of the depth of the shovel blade entering the slide and can also prevent the shovel blade 2 from moving laterally in the slide during use. After the shovel bar 2 is slid into the slide, the slot on the shovel bar bracket 21 corresponds perfectly to the position of the slot in the slide, forming a through groove (not shown in the figure). At this time, a sliding button (not shown in the figure) is provided at the position of the through groove on the outer end of the housing 1. One end of the sliding button is located on the outer surface of the housing 1, and the other end passes through the through groove to lock the shovel bar 2 in the slide. When the shovel bar is damaged and needs to be replaced, simply push the sliding button to make the sliding button exit the through groove, and slide the shovel bar 2 out of the slide for replacement.

[0075] In this embodiment, the surfaces of the shovel body and the double-sided guide bar body facing the cleaning roller together form a complete garbage guide arc surface. The garbage guide channel has two or more arc surfaces with different friction forces. The section with greater friction is more conducive to the accumulation of fine particles into medium particles, while the section with less friction is more conducive to the rapid flow of medium particles in the garbage channel by taking advantage of the inertia of the cleaning roller. The combined garbage guide channel structure is simple, fixed, reliable, and easy to disassemble.

[0076] Example 2:

[0077] like Figure 5 As shown, in this embodiment, the first limiting part 211, the limiting notch 216, and the first limiting protrusion 217 in Embodiment 1 can also be appropriately deformed. Unlike Embodiment 1, the first limiting part 211 is an acute angle and the lower edge of the first limiting part 211 is inclined downward. The lower surface of the limiting notch 216 is also inclined downward, and the degree of inclination is greater than that of the lower edge of the first limiting part 211. The lower surface of the tip of the first limiting protrusion 217 is provided with an arc-shaped chamfer, and the upper surface of the tip of the first limiting protrusion 217 is provided with a slope. This makes it convenient to press the shovel bracket 21 into the slide from top to bottom. During the pressing process, the arc-shaped chamfer of the lower surface of the tip of the first limiting protrusion 217 slides down along the outwardly inclined surface of the abutting step 42 and then uses the elasticity of the shovel bracket 21 to firmly lock the first limiting protrusion 217 into the groove 43. When the shovel bar 2 is removed, the inclined surface of the upper surface of the tip of the first limiting protrusion 217 slides on the inclined upper surface of the groove 43. The elasticity of the shovel bar bracket 21 can be used to slide the first limiting protrusion 217 upward out of the groove 43. Of course, while removing the shovel bar 2 in this "non-sliding" manner, the double-sided guide bar 6 can also be removed in the same way.

[0078] To achieve a tight and secure fit between the shovel support bracket, the pressure plate, and the fastener, the intersection of the horizontal and vertical end faces of the pressure plate limiting step 41, the abutment step 42, and the limiting notch 216 is designed as an inclined plane, and the intersection of the horizontal and vertical end faces of the corresponding limiting notch 216 is also designed as an inclined plane.

[0079] In this embodiment, the shovel 2 can be pulled out laterally from an opening on the side of the cleaning appliance, or it can be removed by applying upward force to the first limiting protrusion 217 after the cleaning roller is disassembled, thereby separating the shovel 2 from the slide.

[0080] like Figure 6As shown, in a modified design of this embodiment, the limiting notch 216 and the first limiting protrusion 217 are directly omitted from the shovel bar bracket 21. Thus, the shovel bar bracket 21 and the pressure plate 4 are only connected by the first fixing part 211 and the chamfered abutment step 42. The connection between the double-sided guide bar 6 and the fixing member 3 is enhanced by a horizontally positioned transverse groove 35. After sliding off the double-sided guide bar 6, the shovel bar 2 can also be removed by "pulling".

[0081] Example 3:

[0082] like Figure 7 - Figure 9 As shown, unlike Embodiments 1 and 2, in Embodiment 3, the arc surface of the shovel 2, the arc surface of the fixing member 3, and the corresponding arc surface of the cleaning roller form a complete waste guiding channel. The arc surface of the shovel 2 is the arc surface formed on the outer surface of the shovel body. The arc surface of the shovel 2 and the arc surface of the fixing member 3 together form a complete arc surface. The waste guiding channel includes a friction section formed by the arc surface of the shovel 2 and a sliding section formed by the arc surface of the fixing member 3. Fine particulate waste is first shoveled into the waste channel by the shovel 2. The friction force on the surface of the shovel 2 is relatively large. Under the action of the cleaning roller, it continues to roll upward along the waste guiding channel on the surface of the shovel. After the fine particulate waste passes through the joint between the shovel 2 and the fixing member 3, the friction force on the surface of the fixing member 3 is small. Under the action of the cleaning roller, it continues to slide upward on the arc surface of the fixing member 3. In the friction section of the waste guiding channel, it is even more necessary to continuously rub and peel off the fine particles of waste from the ground onto the surface of the friction section to form medium-sized particles of waste as much as possible. After passing through the joint between the shovel bar 2 and the fixing part 3, in the sliding section of the waste guiding channel, the medium-sized particles of waste are subjected to the dual action of the cleaning roller and gravity. It is even more necessary to take advantage of the inertia of the medium-sized particles of waste to be quickly thrown up in the sliding section to reduce the power consumption of the cleaning roller.

[0083] As shown in the figure Figure 9 As shown, the fixing member 3 has an abutment surface 34 at the starting end of the arc surface corresponding to the cleaning roller, and the abutment surface 34 and the abutment surface 202 of the shovel body can slide against each other. The fixing member 3 also has an arc surface that adapts to the direction of the roller brush assembly at the end of the arc surface corresponding to the cleaning roller. The intersection of the arc surface corresponding to the cleaning roller and the arc surface adapted to the direction of the roller brush assembly is the diversion tip 33. Medium-sized particles of waste will pass the diversion tip 33 under the action of the cleaning roller and will be brushed into the roller brush arc surface by the oncoming roller brush assembly. Finally, under the action of the momentum provided by the roller brush assembly, they will fall into the waste box in a parabolic shape along the roller brush arc surface.

[0084] like Figure 8 As shown, the pressure plate 4 is fixedly connected to the fixing member 3, and a slide 9 is formed between the two for the shovel bar 2 to slide in a push-pull manner.

[0085] like Figure 9 As shown, in order to achieve a push-pull sliding connection between the shovel bar 2, the fixing member 3, and the pressure plate 4, the shovel bar bracket 21 is also provided with a third limiting part 213. Correspondingly, the fixing member 3 is provided with a sliding groove 31 that cooperates with the third limiting part 213. The third limiting part 213 has a stepped design, and the corresponding limiting inclined surface 32 also has a matching stepped structure. The cooperative design of the above limiting structures of the shovel bar makes the fit between the shovel bar, the fixing member, and the pressure plate tighter. While realizing the detachable setting of the shovel bar, its tight fit can also effectively collect garbage between the roller and the inner surface of the shovel bar, avoiding problems such as garbage entering the connection gap and accumulating due to loose connection, resulting in odor.

[0086] Example 4:

[0087] like Figures 10-12As shown, unlike Embodiments 1, 2, and 3, in Embodiment 4, a double-sided guide strip 8 is movably connected to the top surface of the fixing member 3. The double-sided guide strip 8 includes a double-sided guide strip bracket 81 and a double-sided guide strip body 80 covering the double-sided guide strip bracket 81. The arc surface of the shovel 2, the arc surface of the fixing member 3, the arc surface of the double-sided guide strip 8 that fits against the cleaning roller, and the corresponding arc surface of the cleaning roller form a complete waste guiding channel. The arc surface of the shovel 2 is the arc surface formed on the outer surface of the shovel body 20. The arc surface of the shovel 2, the arc surface of the fixing member 3, and the arc surface of the double-sided guide strip 8 together form a complete arc surface. The waste guiding channel includes a friction section formed by the arc surface of the shovel 2, a sliding section formed by the arc surface of the fixing member 3, and a throwing section formed by the arc surface of the guide strip 8 that fits against the cleaning roller. Fine-particle waste is first shoveled into the waste channel by the shovel bar 2. The friction on the surface of the shovel bar 2 is relatively high, and under the action of the cleaning roller, it continues to roll upwards along the waste guide channel. After passing the joint between the shovel bar 2 and the fixing member 3, the friction on the surface of the fixing member 3 is lower, and under the action of the cleaning roller, it continues to slide upwards on the curved surface of the fixing member 3. In the friction section of the waste guide channel, it is necessary to continuously rub and peel away the fine-particle waste from the ground, forming medium-sized particles as much as possible. After passing the joint between the shovel bar 2 and the fixing member 3, in the sliding section of the waste guide channel, the medium-sized particles are subjected to the combined action of the cleaning roller and gravity. It is necessary to utilize the inertia of the medium-sized particles to quickly throw them up in the sliding section to reduce the power consumption of the cleaning roller. In the throwing section of the waste guide channel, it's crucial to allow medium-sized particles of waste to roll again under the friction of the surface. This ensures they retain a rotating posture as they leave the channel, allowing them to travel further on their subsequent trajectory into the waste bin and preventing excessive accumulation in the throwing section. Furthermore, the double-sided guide strip 8 can be detached for cleaning, meaning the throwing section of the waste guide channel can be removed and cleaned independently. This significantly reduces the difficulty of cleaning fine particles deposited in the waste guide channel, facilitating more thorough and regular cleaning by the user.

[0088] As needed, such as Figure 12As shown, the top surface of the fixing member 3 can also be provided with multiple limiting guide grooves 36. The double-sided guide strip bracket 81 can be movably connected to the top surface of the fixing member 3 through the multiple limiting guide grooves 36. The double-sided guide strip bracket 81 is provided with multiple limiting ribs 812 that are engaged with the limiting guide grooves 36 on the top surface of the fixing member 3. When subjected to an external force along the extension direction of the limiting guide groove 36, the double-sided guide strip 8 can slide along the limiting guide groove 36. When subjected to an external force perpendicular to the top surface of the fixing member 3 and upward, the double-sided guide strip 8 can be taken out upward. The double-sided guide strip bracket 81 is covered with the double-sided guide strip body 80. Because the double-sided guide strip bracket 81 needs to achieve a fixed connection with the fixing member 3 and provide a certain supporting force for the double-sided guide strip body 80, the double-sided guide strip bracket 81 is designed to be made of a rigid material. One side of the double-sided guide strip body 80 is the very end of the waste guiding channel, and the other side is the starting part where the roller brush assembly brushes away fine particles of waste into the roller brush channel. Both sides of the double-sided guide strip body 80 are in direct contact with the waste. Under the action of the cleaning roller and the roller brush assembly, we hope to use the friction of the surface of the double-sided guide strip body 80 to make the fine particles of waste roll rather than slide on its surface. To improve the friction between it and the fine particles of waste and achieve a better cleaning effect, the double-sided guide strip body 80 is designed to be made of a soft material, such as silicone.

[0089] The double-sided guide strip body 80 has an arc surface at the end corresponding to the cleaning roller, which is also adapted to the roller brush assembly. The intersection of the arc surface corresponding to the cleaning roller and the arc surface adapted to the roller brush assembly is the diversion tip 801. Medium-sized particles of waste, after passing the diversion tip 801 under the action of the cleaning roller, will be brushed into the roller brush arc surface by the oncoming roller brush assembly, and finally fall into the waste box in a parabolic shape along the roller brush arc surface under the action of the momentum provided by the roller brush assembly.

[0090] The above embodiments further disclose in detail a detachable and modular waste guiding channel for cleaning appliances disclosed in this invention. It includes a shovel structure consisting of a shovel support and a shovel body connected to the shovel support, and a detachable fixing component that fixes the shovel support to the housing of the cleaning appliance. Partial surfaces of the shovel body and the detachable fixing component form a complete waste guiding arc surface. The waste guiding channel has two or more arc surfaces with different friction forces. The section with higher friction is more conducive to the accumulation of fine particles into medium particles, while the section with lower friction is more conducive to the rapid flow of medium particles in the waste channel by utilizing the inertia of the cleaning roller. The modular waste guiding channel has a simple, reliable, and easy-to-disassemble structure.

[0091] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions or combinations can be made to some structures (technical features) in one or more embodiments.
