Description

Technical Field

[0001] This utility model mainly relates to the field of home cleaning equipment technology, specifically a bed cleaning robot with a flared suction inlet. Background Technology

[0002] Home cleaning equipment refers to a general term for tools or automated devices designed specifically for residential settings such as homes, apartments, and dormitories to remove dust, debris, stains, mites, and other pollutants from the environment. It encompasses various types, including manual (such as brooms and mops) and semi-automatic and fully automatic (such as robotic vacuum cleaners and vacuum cleaners). The core functions revolve around cleaning different areas such as floors, walls, and furniture surfaces. Some also integrate additional functions such as sterilization, mite removal, and drying, aiming to reduce the intensity of manual cleaning through technological optimization and improve the cleanliness and comfort of the living environment.

[0003] Bed surface cleaners are a subcategory of home cleaning equipment specifically designed for the surfaces of soft furniture such as mattresses, beds, and sofas. They are specifically designed to remove dust, dander, hair, and hidden mites from these surfaces. Based on the cleaning needs of soft surfaces, they typically possess core functions such as vacuuming and high-temperature sterilization. Operated manually or semi-automatically, they solve the problems of traditional cleaning tools struggling to thoroughly clean bed surfaces and leaving residues. Existing bed surface cleaners often have a unibody design for the filter and dust cup, requiring complete soaking and rinsing during cleaning. This results in long drying times and the potential for clogging or deformation of the filter due to prolonged soaking. Furthermore, the suction port is often cylindrical or narrow at a small angle, failing to fully cover the area cleaned by the roller brush, allowing dust mites and dirt to escape. Utility Model Content

[0004] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a bed cleaning robot with a flared suction inlet. This solves the problem mentioned in the background that most products have an integrated design of the filter assembly and dust cup, requiring overall immersion and rinsing during cleaning, which leads to clogging or deformation of the filter pores due to prolonged immersion in water.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A bed cleaning robot with a flared suction inlet includes a main body, a filter dust collection assembly on the top of the main body, an obstacle avoidance sensor installed on the outer wall of the main body near the filter dust collection assembly, silicone drive wheels rotatably connected to the bottom of the main body, a suction port on the bottom of the main body, and a roller brush rotatably connected to one side of the suction port.

[0006] The dust collection and filtration assembly includes a dust cup and a positioning seat. The positioning seat is fixed to the top of the main body, and the dust cup and the positioning seat are detachably connected.

[0007] Furthermore, the inner wall of the positioning seat is provided with a ring-shaped engaging protrusion, and the dust cup has a rotating guide groove on the outer surface of the corresponding engaging protrusion for use with it. The interior of the dust cup forms a cavity for accommodating dust mites.

[0008] Furthermore, the dust cup has a filter disc threadedly connected to the inner wall near the positioning seat. An air guide plug is fixed at the axis of the filter disc. The positioning seat has a dust collection air guide plug sleeve at the corresponding position at the axis for use with the air guide plug. The filter disc, the air guide plug, and the dust collection air guide plug sleeve all have a mesh filter screen in their axial holes.

[0009] Furthermore, the suction port has a funnel-shaped expansion structure, with the larger opening end close to one side of the roller brush and tilted towards one side of the roller brush. The air outlet of the suction port is connected to a corrugated pipe, which is located inside the main body. The other end of the corrugated pipe is rotatably connected to a quick connector, which is threadedly connected to the corresponding interface at the bottom of the dust cup.

[0010] Furthermore, the top of the main body has a slot at the corresponding dust cup installation position, the slot allows the quick connector to move during dust cup loading and unloading, and the main body has a vent on the other side of the slot, one end of the vent is connected to the bottom of the positioning seat, and the other end is connected to the suction fan installed in the main body. The dust collection and air guide sleeve is hollow inside, and the dust collection and air guide sleeve is connected to the vent and the suction fan in sequence to form an airflow channel acting on the dust cup.

[0011] Furthermore, the obstacle avoidance sensors are distributed in an arc shape along the edge of the main body on this side, and each obstacle avoidance sensor is equally spaced along the arc-shaped extension direction, so as to expand the obstacle avoidance detection range through the arc-shaped distribution of obstacle avoidance sensors.

[0012] Furthermore, the bottom of the main body is provided with multiple sterilization grooves. The sterilization grooves are opened on one side of the roller brush and are located away from the dust suction port. Each sterilization groove is equally spaced along the corresponding area of ​​the bottom of the main body, corresponding to the position of the ultraviolet germicidal lamp installed inside the main body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The dust cup and positioning seat are engaged by a ring-shaped locking protrusion and a rotating guide groove. Users can easily engage or disengage the dust cup by simply rotating it, enabling quick initial disassembly. The bottom of the dust cup connects to the suction channel via a quick-connect fitting that combines a corrugated tube and a threaded connection. During disassembly, the quick-connect fitting rotates synchronously with the dust cup without tangling with the corrugated tube, ensuring complete separation of the dust cup from the suction channel and preventing the accumulation of residual impurities. Meanwhile, the air guide insertion post on the filter disc axis provides a docking reference for the assembly of the dust cup and positioning seat, and also serves as a gripping point for disassembling the filter disc. This allows users to quickly remove the filter disc and clean the inside of the dust cup. Furthermore, the filter disc can shield impurities during disassembly, preventing secondary contamination and making disassembly, cleaning, and assembly easier.

[0014] 2. The flared suction port structure, combined with an airflow system, achieves precise and efficient adsorption of dust mites and dirt. The larger opening end is close to the roller brush and angled towards it, completely enveloping the cleaning area of ​​the roller brush and preventing dust mites and dirt stirred up by the high-speed rotation of the roller brush from escaping through gaps. At the same time, the air outlet of the flared suction port is connected to the quick connector at the bottom of the dust cup through a corrugated tube. Together with the suction fan, vent, and dust collection guide sleeve, a sealed airflow channel is formed. When the suction fan is working, it can generate a stable negative pressure in the channel. The negative pressure is conducted through the dust cup, quick connector, and corrugated tube to the flared suction port, creating a strong suction at the suction port. This suction draws the floating dust adsorbed by the roller brush cleaning layer and the dust mites stirred up from deep within into the dust cup. The arc-shaped obstacle avoidance sensor expands the detection range and reduces equipment collisions to ensure the integrity of the cleaning path. The sterilization tank at the bottom of the main unit is far from the suction port and evenly distributed, which can prevent dust from blocking ultraviolet rays, achieving thorough disinfection of the bed surface after the roller brush cleaning, further improving the cleanliness and hygiene of the bed surface.

[0018] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Please refer to the appendix carefully. Figure 1-4 A bed cleaning robot with an flared suction inlet includes a main body 1, a filter dust collection component 2 on the top of the main body 1, an obstacle avoidance sensor 3 installed on the outer wall of the main body 1 near the filter dust collection component 2, a silicone drive wheel 4 rotatably connected to the bottom of the main body 1, a suction port 5 at the bottom of the main body 1, and a roller brush 6 rotatably connected to one side of the suction port 5.

[0021] The filter dust collection assembly 2 includes a dust cup 21 and a positioning seat 22. The positioning seat 22 is fixed to the top of the main body 1, and the dust cup 21 and the positioning seat 22 are detachably connected.

[0022] In this embodiment, as Figure 3 As shown, the inner wall of the positioning seat 22 is provided with a ring-shaped engaging protrusion 221, and the dust cup 21 has a rotating guide groove 211 on the outer surface of the corresponding engaging protrusion 221 for use with it. The interior of the dust cup 21 forms a cavity for accommodating dust mites.

[0023] With the above structure, the positioning seat 22 and the dust cup 21 are connected by a mounting and dismounting structure with the engagement protrusion 221 and the rotating guide groove 211, which simplifies the mounting and dismounting process and improves the convenience of cleaning and maintaining the dust cup 21. At the same time, the ring-shaped engagement protrusion 221 and the corresponding guide groove form a multi-point uniform engagement, which can ensure that the dust cup 21 fits tightly with the positioning seat 22 after assembly, and prevent the dust cup 21 from shifting due to vibration when the equipment is working.

[0024] In this embodiment, as Figure 3 and Figure 4As shown, a filter disc 212 is threadedly connected to the inner wall of the dust cup 21 near the positioning seat 22. An air guide plug 2121 is fixed at the axis of the filter disc 212. A dust collection air guide plug sleeve 222 is provided at the corresponding position at the axis of the positioning seat 22 for use in conjunction with the air guide plug 2121. The axial holes of the filter disc 212, the air guide plug 2121 and the dust collection air guide plug sleeve 222 are all provided with a mesh filter screen.

[0025] Through the above structure, firstly, the filter disc 212 can directly block dust, dust mites and other impurities inside the dust cup 21 when the dust cup 21 is disassembled, effectively preventing impurities from accidentally falling out from the joint between the dust cup 21 and the positioning seat 22, reducing subsequent cleaning and maintenance work; secondly, when the filter disc 212 is disassembled, the structure of the air guide plug 2121 protruding from the surface of the filter disc 212 can serve as a force-applying gripping point, taking into account both filtration function and ease of use; finally, when the dust cup 21 and the positioning seat 22 are assembled, the air guide plug 2121 and the dust collection air guide plug 222 form a plug-in fit, and their coaxial structure does not affect the rotational movement of the dust cup 21, providing an additional docking reference point when the dust cup 21 and the positioning seat 22 are assembled, and also enhancing the connection stability between the dust cup 21 and the positioning seat 22, ensuring smooth passage of negative pressure airflow.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, the suction port 5 has a funnel-shaped expansion structure. The larger end of its opening is close to one side of the roller brush 6 and is tilted towards one side of the roller brush 6. The air outlet of the suction port 5 is connected to a corrugated pipe, which is located inside the main body 1. The other end of the corrugated pipe is rotatably connected to a quick connector, which is threadedly connected to the corresponding interface at the bottom of the dust cup 21.

[0027] With the above structure, the dual structure of one end of the quick connector being rotatably connected to the bellows and the other end being threadedly connected to the bottom interface of the dust cup 21, firstly lays the necessary conditions for the complete disassembly and cleaning of the dust cup 21, which can realize the complete separation of the dust cup 21 from the suction channel. The rotatable connection between the quick connector and the bellows effectively avoids operational obstacles during disassembly, and the bellows will not be tangled or pulled due to rotation.

[0028] In this embodiment, as Figure 3 As shown, the top of the main body 1 has a slot at the installation position of the corresponding dust cup 21. The slot allows the quick connector to move during the installation and removal of the dust cup 21. On the other side of the main body 1 corresponding to the slot, there is a vent. One end of the vent is connected to the bottom of the positioning seat 22, and the other end is connected to the suction fan installed in the main body 1. The dust collection and air guide sleeve 222 is hollow inside, and the dust collection and air guide sleeve 222 is connected to the vent and the suction fan in sequence to form an airflow channel acting on the dust cup 21.

[0029] With the above structure, the slot on the top of the main body 1 corresponding to the installation position of the dust cup 21 provides space for the quick connector to move. When the dust cup 21 is disassembled or installed, the quick connector can move flexibly along the track of the slot, reducing the difficulty of loading and unloading operations and improving the convenience of user maintenance.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the obstacle avoidance sensor 3 extends in an arc shape along the edge of the main body 1 on this side. Each obstacle avoidance sensor 3 is arranged at equal intervals along the arc-shaped extension direction, so as to expand the obstacle avoidance detection range through the arc-shaped distribution of obstacle avoidance sensors 3.

[0031] Through the above structure, the arc-shaped distribution of obstacle avoidance sensor 3 breaks the detection limitations of straight-line arrangement. It can form a wide-angle detection area based on the edge of the main body 1, greatly reducing the blind spot of obstacle avoidance detection, avoiding the omission of obstacles such as the edge of bedding and the corner of furniture due to the narrow detection range of straight lines, and reducing the risk of collision.

[0032] In this embodiment, as Figure 2 As shown, the bottom of the main body 1 is provided with multiple sterilization grooves 7. The sterilization grooves 7 are opened on one side of the roller brush 6 and are located away from the dust suction port 5. Each sterilization groove 7 is equally spaced along the corresponding area of ​​the bottom of the main body 1, corresponding to the position of the ultraviolet sterilization lamp installed inside the main body 1.

[0033] With the above structure, the position of the sterilization tank 7 can not only prevent dust and debris sucked in by the suction port 5 from accumulating and blocking the sterilization tank 7, ensuring that the light emitted by the ultraviolet sterilization lamp can be projected onto the bed surface without obstruction, but also form a continuous cleaning and sterilization connection with the cleaning action of the roller brush 6. Multiple sterilization tanks 7 are set at equal intervals along the corresponding area at the bottom of the main body 1. With the ultraviolet sterilization lamps that are precisely corresponding to the tank positions, the sterilization area of ​​the bed surface can be evenly covered, the sterilization effect can be enhanced, and the cleanliness of the bed surface can be further improved.

[0034] The specific operating procedure of this utility is as follows: It should be noted that the silicone drive wheel 4 of this device has a built-in independent drive motor, enabling the silicone drive wheel 4 to move forward and backward. Simultaneously, each silicone drive wheel 4 within the main body 1 is equipped with a corner motor featuring an angle encoder, allowing the silicone drive wheel 4 to rotate 45° left and right to meet the cleaning needs of different areas of the bed surface. The roller brush 6 is composed of a metal drive roller, with a drive motor on one side. The roller body is detachably covered with a cleaning layer using Velcro. This cleaning layer is made of a composite material of fiber and nylon bristles, which can both shake up deep-seated dust mites through the high-speed rotation of the brush and absorb surface dust using its fiber material. The detachable structure facilitates user cleaning. Additionally, the main body 1 contains a lithium battery. The battery powers the entire machine. A power indicator light is located on the top of the main body 1, which can provide real-time feedback on the remaining power status through different light colors or flashing frequencies. When the power is low, it can be charged through the Type-C charging port located on the other side of the obstacle avoidance sensor 3 on the main body 1. Several heat dissipation holes are opened at the bottom of the main body 1 to dissipate the heat generated by the internal drive motor and the suction fan in a timely manner, ensuring the long-term stable operation of the equipment. The main body 1 also contains a control unit, which is electrically connected to the drive motor of the silicone drive wheel 4, the drive motor of the roller brush 6, the suction fan, the ultraviolet germicidal lamp, the obstacle avoidance sensor 3, the power indicator light, and the lithium battery. It can realize the control of the equipment's movement path, cleaning intensity, sterilization start and stop, obstacle avoidance protection, power display, and power supply management.

[0035] When starting the device, press the control button on the main body 1. The control body will then start the various functional modules. The silicone drive wheel 4 will rotate under the drive motor, moving the main body 1 on the bed surface. During the movement, the obstacle avoidance sensor 3 will scan the surrounding environment in real time. If the edge of the bed or an obstacle is detected, the control body will immediately adjust the direction of the silicone drive wheel 4 to avoid collision.

[0036] At the same time, the drive motor of the roller brush 6 drives the drive roller to rotate at high speed. The outer composite material cleaning layer adsorbs dust mites and surface dust from deep within the bed fibers onto the cleaning layer surface through patting and friction. The ultraviolet sterilization lamp at the bottom of the main body 1 is turned on simultaneously, and ultraviolet light is projected onto the bed surface through the sterilization tank 7 to sterilize the area cleaned by the roller brush 6.

[0037] During the cleaning process, the suction fan inside the main body 1 starts simultaneously. The suction fan creates a negative pressure field inside the main body. This negative pressure is transmitted to the positioning seat 22 through the ventilation port connected to the suction fan. Since the positioning seat 22 and the dust cup 21 are interconnected, the negative pressure is further transmitted to the quick connector through the interface at the bottom of the dust cup 21, and then guided to the suction port 5 through the corrugated pipe, so that a stable negative pressure suction force is formed at the suction port 5.

[0038] The suction port 5 has a funnel-shaped expansion structure, with the larger end of its opening close to the roller brush 6, which can fully cover the cleaning area of ​​the roller brush 6, bringing all the dust, dust mites and surrounding debris adsorbed by the cleaning layer into the suction range. Under the drive of the negative pressure airflow, these debris pass through the suction port 5, the corrugated pipe and into the cavity of the dust cup 21.

[0039] The dust cup 21 is made of transparent PC material, which makes it easy to observe the accumulation of debris inside. The filter plate 212 and the air guide plug 2121 on the axis of the filter plate 212 are threaded together and have a mesh filter screen. The mesh diameter of the filter screen of the filter plate 212 and the air guide plug 2121 is smaller than the mesh diameter of the surface of the dust collection air guide plug sleeve 222. The filter screen of the filter plate 212 and the air guide plug 2121 can effectively intercept solid debris such as dust and dust mites and prevent them from entering the interior of the positioning seat 22 and blocking the airflow channel.

[0040] The filter screen of the dust collection and air guide sleeve 222 plays a role in airflow guidance, ensuring that the negative pressure airflow passes smoothly. The filtered clean airflow passes through the dust collection and air guide sleeve 222 and the vent in sequence into the suction fan, and finally is discharged from the air outlet around the heat dissipation hole at the bottom of the main body 1.

[0041] When the amount of debris in the dust cup 21 reaches a certain level, turn off the power to the device. First, hold the dust cup 21 and rotate it counterclockwise to disengage the rotating guide groove 211 on the outer surface of the dust cup 21 from the engaging protrusion 221 on the inner wall of the positioning seat 22, thus initially removing the dust cup 21 from the positioning seat 22. Then, unscrew the quick connector connecting the bottom of the dust cup 21 to the bellows to completely separate the dust cup 21 from the suction channel. With the help of the protruding structure of the air guide plug 2121, disassemble the filter disc 212 and thoroughly clean the inside of the dust cup 21.

[0042] After cleaning, first re-thread the quick connector to the bottom of the dust cup 21, then align the rotating guide groove 211 of the dust cup 21 with the engaging protrusion 221, and rotate the dust cup 21 in the opposite direction until the engaging protrusion 221 is fully embedded in the locking position of the rotating guide groove 211, so that it can be restarted and used later.

[0043] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
