[0036] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0037] A garbage bin module with a dust scraping member and a floor sweeper having the module according to a preferred embodiment of the present utility model; as Figure 1-2 and Figure 8-9As shown in the figure, it includes a bottom shell 10 and a top shell 11 arranged on the bottom shell. One side of the bottom shell and the top shell is fixedly connected by threads, and the other side is fixedly connected by a front shell 13. The bottom shell consists of a partial circle and a direction. The main part of the top shell 11 is also circular in design, while the front cover part is mainly square in design. The circular design has better aesthetics, but it cannot clean corners and other places. Therefore, a square part is set to facilitate cleaning corners and other places, making the usage scenario more diverse. At the same time, in order to prevent the square edge from colliding with the wall and damaging the sweeper when moving, multiple groups of induction components 15 are arranged on the side of the bottom shell. The distance between the sweeper and the obstacle is sensed through the induction components to prevent the sweeper from hitting the obstacle and causing a malfunction. A cleaning component 17 is arranged on the bottom shell, as well as a dust suction channel 100 and a dust suction port 116 connected to the cleaning component. The garbage and sundries cleaned by the cleaning component pass through the dust suction channel and then enter the garbage bin module 22 through the dust suction port for storage. A blower 21 connected to the garbage bin is also arranged on the bottom shell. The rotation of the blower creates a negative pressure in the garbage bin, thereby generating an air flow in the dust suction channel to suck the garbage and dust on the cleaning component into the garbage bin module. A control board 20 for controlling the operation of the blower is also arranged on the bottom shell, as well as a battery 19 for supplying power to the control board. A charging interface 18 connected to the battery is arranged on the housing to facilitate charging the battery. It is also possible to directly connect the power supply to the control board through the charging interface without setting a battery to make the sweeper work. At this time, the working range of the sweeper is relatively limited. To facilitate the movement of the sweeper, a roller assembly 16 is arranged at the lower end of the bottom shell to control the forward, backward, and turning of the sweeper, thereby realizing the 360-degree non-dead-angle rotation of the sweeper for cleaning work.

[0038] Specifically, as Figure 11-12 shown, the garbage bin module 22 includes a garbage bin outer shell 222 with a hollow interior, a garbage bin base 221 arranged at the bottom of the garbage bin outer shell, and a garbage bin cover 223 arranged above the garbage bin outer shell. The garbage bin base, the garbage bin outer shell, and the garbage bin cover enclose to form a garbage bin 225 for storing cleaning garbage. A dust suction port 220 is arranged on the garbage bin outer shell. The garbage bin is connected to the cleaning component through a dust suction channel. The dust suction channel includes a dust suction channel cover 24 arranged on the bottom shell. A sealing ring can be arranged between the dust suction channel cover and the bottom shell to increase the sealing performance. A dust suction channel is formed between the dust suction channel cover and the bottom shell, and the garbage bin is connected to the cleaning component through the dust suction channel, enabling the garbage and dust cleaned by the cleaning component to enter the garbage bin through the dust suction channel. A ventilation port 210 is also arranged on the garbage bin outer shell and is connected to the blower 21, thereby forming an air flow channel between the garbage bin and the blower. The garbage bin forms a negative pressure area under the action of the blower to suck the garbage cleaned by the cleaning component into the garbage bin.

[0039] Furthermore, as Figure 11As shown, the waste bin 22 is connected to the fan 21 through a fan connecting piece 211. A wind guiding channel is provided between the fan connecting piece and the waste bin so that the negative pressure generated by the fan enters the waste bin after passing through the wind guiding duct 224, and then the waste cleaned by the cleaning component is sucked into the waste bin through the dust suction channel. To prevent waste or dust from entering the wind guiding channel, measures such as a separation net can be set between the wind guiding duct and the waste bin for isolation. At the same time, the fan outlet and the air guiding port of the fan are arranged offset in the vertical direction, which further prevents dust and the like from entering the fan.

[0040] Furthermore, as Figure 11 - Figure 14 shown, in order to facilitate the removal of the waste bin cover 223 from the waste bin housing 222, two sets of push-pull members 229 are oppositely arranged between the waste bin cover and the upper end face of the waste bin housing, and the push-pull members can move relative to the waste bin cover. A cover-lifting groove 2290 is left between the push-pull members and the waste bin cover. When the waste bin cover does not need to be removed, the push-pull members are placed above the cover-lifting groove and seal the cover-lifting groove. At this time, it is not convenient to remove the waste bin cover. To facilitate the removal of the waste bin cover, a lifting hole 2291 is provided on the lifting member 229. By pushing the lifting member through the lifting hole, the cover-lifting groove can be opened. Then, two fingers are respectively placed in a set of cover-lifting grooves, and the waste bin cover can be removed from the waste bin housing to pour out the waste.

[0041] Furthermore, as Figure 11 and Figure 14-17 shown, in order to facilitate the dumping of waste, the waste bin can also be opened by opening the waste bin base 221. The waste bin base is connected to the waste bin housing through a rotating shaft 130. A torsion spring (not shown in the figure) can be provided at the rotating shaft. The torsion spring closes the waste bin when the waste bin base is in the natural state, and the waste bin can be opened only when a force is applied. A base sliding door 231 is also provided at the lower end of the waste bin base. The base sliding door is also connected to the waste bin base through a rotating shaft and a torsion spring. A groove for conveniently pulling the base sliding door is provided on the base sliding door. When the base sliding door is pulled by pulling the groove, the waste bin base can be pulled open by applying force to the base sliding door to dump the waste, avoiding the flying of dust when dumping waste.

[0042] Furthermore, as Figure 12-14 and Figure 16As shown, in order to prevent the dust in the waste bin 225 from entering the fan, an air guide cavity 226 is independently arranged in the waste bin base 221. The air guide cavity and the waste bin are separated by a separation net 227 to achieve air circulation while preventing dust or particulate impurities from entering the air guide cavity. A duct 224 is arranged between the air guide cavity and the air outlet. The duct passes through the waste bin, enabling the air guide cavity to occupy a very small space at the lower end of the waste bin, thereby increasing the volume of the waste bin to accommodate more cleaning objects. To prevent the dust adhering to the separation net 227 from affecting the air circulation effect, a dust scraping member 228 is also arranged in the waste bin. When the waste bin base is opened, the dust scraping member can be driven to rotate with the waste bin base and scrape the dust on the separation net, improving the cleaning effect.

[0043] Furthermore, as Figure 16 - Figure 17 shown, a dust scraping member insertion hole 2310 is arranged on the waste bin base. The dust scraping member includes a dust scraping member insertion post 2280 inserted into the dust scraping member insertion hole, connecting the dust scraping member to the waste bin base and facilitating the replacement of the dust scraping member. The dust scraping member 228 also includes a follower arm 2281 integrally formed with the dust scraping member and a driven arm 2283 connected to the follower arm. The follower arm and the driven arm are connected through a bending hole 2282. When the waste bin base is closed, the follower arm is perpendicular to the waste bin base, and the driving arm is placed under the waste bin cover. When the waste bin base is rotated, the follower arm rotates with the rotation of the waste bin. After rotating to a certain extent, the follower arm contacts the driving arm at the bending hole. After continuous rotation, the follower arm can drive the driven arm to move together, and during the movement, it sweeps across the surface of the separation net, scraping the dust on the surface of the separation net. When the waste bin base is closed, the dust on the separation net is scraped again with the opposite movement to fully scrape the dust on the separation net. To further scrape the dust on the separation net, a protruding dust scraping part 2284 is arranged on the driven arm. The dust scraping part keeps contacting the separation net for dust scraping, and the dust scraping effect is better. Since the dust scraping member deforms during movement, the dust scraping member should be an elastic member, which can cause the follower arm and the driven arm to bend under force and be driven by the follower arm to move, and the driven arm should keep closely attached to the separation net for a better dust scraping effect. To facilitate the deformation of the driven arm, a bending part 2285 is arranged on the driven arm to improve the effect of the driven arm keeping closely attached to the separation net when following the follower arm to move.

[0044] Furthermore, as Figure 3-7As shown in the figure, the lower front cover 131 is arranged at the front side of the lower end of the bottom shell. Multiple groups of teeth 1310 extending in the vertical direction are arranged on the lower front cover. Multiple groups of support ribs 1311 are arranged between the teeth and the inner wall of the lower front cover. A lower flange 101 corresponding to the support ribs is arranged on the bottom shell, and a card hole 102 corresponding to the teeth is arranged on the lower flange. The teeth are inserted into the card holes to prevent the bottom shell from moving back and forth relative to the lower front cover. At the same time, the lower flange placed on the support ribs also reduces the extension height of the lower flange, improving the strength of the bottom shell. The lower front cover wraps the bottom shell from three sides, with only one side completely wrapping and the other two sides only partially wrapping. A jack 1312 is also arranged on the lower front cover 131. The upper front cover is arranged above the lower front cover and is connected to the lower front cover. An insertion post 13000 corresponding to the jack is arranged on the upper front cover. The upper front cover is fixed to the lower front cover by inserting the insertion post into the jack and then using a screw to pass through the jack, which is more convenient for the alignment and assembly of the lower front cover and the upper front cover. An upper step 1313 is arranged on the lower front cover, and a lower step 13002 corresponding to the upper step is arranged at the lower end of the upper front cover. Using the step method not only facilitates the assembly of the upper front cover and the lower front cover but also increases the waterproofness of the product, preventing water stains from entering the inside of the sweeper through the connection seam during the use of the sweeper and affecting the components of the sweeper. A sealing structure such as a sealing ring can also be arranged at the connection to increase the sealing performance of the connection.

[0045] Further, as Figure 3-7 shown, the upper front cover 130 includes a lower part 1300 of the upper front cover connected to the lower front cover and an upper part 1301 of the upper front cover connected to the top shell 11. The two ends of the upper part and the lower part of the upper front cover are connected by a connecting part 1303, forming a hollow part 1302 between the upper part and the lower part of the upper front cover. A card slot 13010 is arranged on the upper part 1301 of the upper front cover. Multiple groups of ribs 13011 are arranged in the card slot, and a limiting area 13013 is formed between every two groups of ribs. A convex tongue 114 corresponding to the limiting area is arranged on the top shell 11. The convex tongue is placed in the limiting area and forms a clamping structure with the card slot to connect the top shell and the upper front cover. Since the upper front cover and the lower front cover are locked, the top shell and the bottom shell can be connected and fixed, facilitating the assembly of the product. It should be noted that the width of the limiting area should be the same as or basically the same as the width of the convex tongue to prevent the top shell from rotating and also facilitate alignment during assembly. A support platform 13012 is also arranged on the upper part of the upper front cover, and a notch 112 corresponding to the support platform is arranged on the top shell. A concave part 113 corresponding to the support platform is also arranged on the top shell. When the lower front cover is connected to the top shell, the support platform is inserted into the notch and located at the concave part, providing a support force for the top shell. Due to the existence of the insertion post 13000, in order to facilitate the connection between the front cover and the bottom shell, an arc-shaped concave cavity 103 corresponding to the front cover is arranged on the bottom shell. The upper end of the insertion post should be lower than the top end of the arc-shaped concave cavity, so that the arc-shaped concave cavity also has a certain limiting effect on the insertion post, improving the limiting performance of the assembly and making the assembly more convenient. In order to enhance the sensing ability of the sensing component, a sensing component window 13001 corresponding to the sensing component is arranged on the front cover, enabling the sensing component to directly transmit and receive signals.

[0046] Furthermore, if Figure 5-6 As shown, the top shell 11 is provided with a battery compartment 111 for fixing the battery, and a garbage bin chamber 110 for placing the garbage bin module, and also includes a fan port 115 connected to the garbage bin module. The fan is placed at the fan port to provide negative pressure for the garbage bin module.

[0047] Furthermore, if Figure 10 As shown, the cleaning assembly 17 includes a cleaning member 172 disposed on the bottom shell, and a motor 170 for driving the cleaning member to rotate. The motor and the cleaning member are driven by a gear box 171, so that the low speed of the motor can drive the cleaning member to rotate at a high speed, thereby improving the cleaning effect. The cleaning member is provided with multiple groups of cleaning wings 1720, which are eccentrically designed to improve the cleaning effect, and the cleaning member is fixed to the bottom shell in the form of a buckle and connected to the gear box, thereby facilitating the replacement of the cleaning member.

[0048] Furthermore, if Figure 2 As shown, the roller assembly 16 includes two sets of driven wheels 160 arranged at the front end of the bottom shell, and two sets of driving wheels 161 arranged at the rear end of the bottom shell. The radius of the driving wheel is larger than that of the driven wheel, and the driven wheel can be driven to move by driving the driving wheel through a motor or other means. The roller assembly also includes a universal wheel 162 arranged on the bottom shell, and the moving direction of the driving wheel is changed by turning the universal wheel, thereby changing the moving direction of the sweeper, so as to realize 360-degree rotation of the sweeper without dead angles.
