Description

Technical Field

[0001] This utility model belongs to the field of toilet cleaning technology, and relates to a cleaning device, particularly a cleaning device for cleaning public areas. Background Technology

[0002] Urinals are a common toilet fixture in men's restrooms. When men use urinals, dust from their feet falls onto the floor around the urinal. Furthermore, urine often drips onto the floor below the urinal, further attracting dust and causing it to become very dirty, requiring frequent cleaning. However, cleaning urinals manually is labor-intensive, and since most cleaning staff are women, frequent cleaning of men's restrooms is inconvenient.

[0003] Patent application CN202122770929.0 discloses a urinal floor cleaning device, comprising a fixed compartment, a movable cleaning structure, and a track structure. The fixed compartment is located on one side of the urinal assembly and contains a charging port and a water supply port. The charging port is connected to an external power source, and the water supply port is connected to a water source. The track structure includes a track laid along the extension direction of the urinal assembly. The movable cleaning structure includes interconnected moving components, a flushing structure, a water-absorbing structure, and a friction structure. The moving components drive the entire movable cleaning structure to move along the track. The flushing structure sprays water onto the floor, the friction structure rubs against the floor, and the water-absorbing structure removes water and debris from the floor. This invention can be used for cleaning multiple urinals, has a high degree of automation, and is simple and reliable to control.

[0004] Although the cleaning equipment described above can clean the area under the urinal and flush it with the water flow after urination, it cannot clean the inner wall and edges of the urinal thoroughly. These areas still require manual wiping and cleaning, which is time-consuming and laborious. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a cleaning device that can not only clean the area below the urinal but also clean the inner wall and edges of the urinal.

[0006] The objective of this utility model can be achieved through the following technical solution: a public area cleaning device, wherein multiple urinals are provided in the public area, and the lower areas of the multiple urinals are interconnected, including:

[0007] The track is located in the area below the urinal, and multiple urinals are arranged along the length of the track;

The two sides of the first cleaning unit are respectively connected to the two grippers. The first cleaning unit is provided with a cleaning surface. When the two grippers rotate in opposite directions, the two sides of the first cleaning unit unfold in opposite directions, so that the cleaning surface is set as a plane, so that the first cleaning unit fits against the inner wall surface of the urinal. When the two grippers rotate towards each other, the two sides of the first cleaning unit close towards each other, so that the cleaning surface is set in a V shape. The opening and closing angle of the V-shaped cleaning surface is changed according to the angle at which the two sides of the first cleaning unit close towards each other.

[0011] In the aforementioned public area cleaning equipment, the first connecting end of the linkage is provided with at least one first cleaning liquid spray nozzle, and the spray direction of the first cleaning liquid spray nozzle is towards the first cleaning part, wherein the first cleaning part is absorbent.

[0012] In the aforementioned public area cleaning equipment, the second cleaning structure includes a housing connected to the second connecting end of the connecting rod, and a slot and a stepped surface are provided on the side of the housing facing away from the first cleaning structure. A spiral soft rubber scraper is provided at the position corresponding to the slot, and a rotating hard brush is provided at the position corresponding to the stepped surface. The spiral soft rubber scraper and the rotating hard brush constitute the second cleaning part.

[0013] In the aforementioned public area cleaning equipment, the spiral soft rubber scraper can rotate circumferentially in a vertical plane, and the rotating hard brush can rotate circumferentially in a horizontal plane, wherein the axial direction of the spiral soft rubber scraper is perpendicular to the axial direction of the rotating hard brush.

[0014] In the aforementioned public area cleaning equipment, there are two spiral soft rubber scrapers with their axes parallel to each other and arranged side by side. There are also two rotating hard bristle brushes with their axes parallel to each other and arranged side by side. The arc surfaces formed by the outermost edges of the two spiral soft rubber scrapers intersect, and the protrusion on one spiral soft rubber scraper corresponds to the concave part on the other spiral soft rubber scraper. The arc surfaces formed by the outermost edges of the two rotating hard bristle brushes are tangent to each other.

[0015] In the aforementioned public area cleaning equipment, a second cleaning liquid spray nozzle is provided on the rotating stiff brush, and the spray direction of the second cleaning liquid spray nozzle is consistent with the opening direction of the slot; a water suction port is also provided on the housing, and the water suction port and the slot are located on the same side of the housing.

[0016] In the aforementioned public area cleaning equipment, a liquid storage tank and two side-by-side boxes are installed on the support. The two boxes are a clean water tank and a wastewater tank, respectively. The liquid storage tank is used to store cleaning liquid. The clean water tank is connected to the first cleaning liquid spray port and the second cleaning liquid spray port through a conduit. The wastewater tank is connected to the suction port through a conduit and a vacuum pump. The liquid storage tank is connected to the first cleaning liquid spray port and the second cleaning liquid spray port through a conduit.

[0017] In the aforementioned public area cleaning equipment, the robotic arm includes a first telescopic arm and a second telescopic arm, and the first telescopic arm and the connector, the first telescopic arm and the second telescopic arm, and the second telescopic arm and the connecting rod are connected by movable joints. The movable joints can change the included angles between the first telescopic arm and the ground, between the first telescopic arm and the second telescopic arm, and between the second telescopic arm and the connecting rod.

[0018] The cleaning equipment mentioned above for public areas includes:

[0019] The base frame is installed on a wall or the ground and has mounting grooves along its length.

[0020] The drive structure includes a drive motor connected to the bottom of the mounting slot, and the output end of the drive motor is connected to a lead screw to form the track, wherein the support is screwed onto the lead screw.

[0021] The base frame has a cleaning tank located at the end furthest from the drive motor. Inside the cleaning tank is a cleaning chamber, with a water supply pipe and a first drain pipe installed on the chamber wall. A cleaning trough is located at the bottom of the cleaning chamber, connected to a second drain pipe. When the support is moved into the cleaning chamber, the position of the clean water tank corresponds to the position of the water supply pipe, the position of the wastewater tank corresponds to the position of the first drain pipe, and the position of the second cleaning section corresponds to the position of the cleaning trough.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] (1) This utility model provides a public area cleaning device. By setting a first cleaning structure and a second cleaning structure, it can not only clean the area under the urinal, but also clean the urinal itself, solving the problem of manual cleaning of public areas and saving time and effort.

[0024] (2) By setting two grippers, the shape of the first cleaning section can be changed to match the inner wall and edge of the urinal. It can also effectively squeeze out the cleaning liquid or water inside the first cleaning section, ensuring that the first cleaning section is dry and clean, and achieving the health and environmental protection of the first cleaning section.

[0025] (3) The spiral soft rubber scraper can remove residual dirt and water stains on the floor below the urinal, while the rotating hard brush can effectively remove dried and stubborn stains on the floor below the urinal. In addition, by setting up a stepped surface, the height difference between the spiral soft rubber scraper and the rotating hard brush is effectively eliminated, so that both can contact the ground at the same time, thereby improving the cleaning effect.

[0026] (4) The water inlet can absorb the residual water on the ground after cleaning, prevent the ground from being slippery, reduce secondary pollution, and ensure that the ground is clean and tidy.

[0027] (5) A 360° fisheye infrared sensor is installed on the connecting rod, and the 360° fisheye infrared sensor has a built-in millimeter-wave radar to accurately determine the position of the urinal and achieve directional cleaning. Moreover, the millimeter-wave radar assists the infrared sensor to filter interference signals such as water mist, reflection or foreign objects blocking the infrared sensor, avoids false triggering of the infrared sensor, and ensures that the cleaning equipment starts the cleaning task only when no one is using the urinal.

[0040] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0041] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0042] like Figures 1 to 6 As shown, this utility model provides a public area cleaning device, in which multiple urinals are provided in the public area, and the areas below the multiple urinals are interconnected, including:

[0043] The track is located in the area below the urinal, and multiple urinals are arranged along the length of the track;

[0044] Support 100 is movably connected to the track and can reciprocate along the length of the track. A joint 110 extends outward from the support 100.

[0045] The robotic arm 200 is rotatably connected to the connector 110 at one end and to the connecting rod 210 at the other end. At both ends of the connecting rod 210, there are a first cleaning structure 230 for cleaning the edge and inner wall of the urinal and a first cleaning structure 220 for cleaning the area below the urinal. The first cleaning structure 220 is provided with a first cleaning part 221 and the second cleaning structure 230 is provided with a second cleaning part. The first cleaning part 221 and the second cleaning part are arranged opposite to each other. The first cleaning part 221 achieves cleaning by deforming to match the edge or inner wall of the urinal, and the second cleaning part achieves cleaning by contacting the area below the urinal.

[0046] In existing technology, public areas of men's restrooms typically include urinals and toilets, with adjacent urinals separated by a partition. This partition has a gap with the ground, allowing the areas beneath multiple urinals to be interconnected. This provides the possibility for the cleaning device of this invention to clean the areas beneath the urinals. However, existing cleaning devices can only clean the area beneath the urinals, not the urinals themselves. Firstly, urine residue remains around the edges of the urinals after urination. Secondly, the automatic cleaning function inside the urinal can only clean a portion of the interior, not the entire area. Thirdly, when the automatic cleaning function fails, the urinal cannot be cleaned promptly, resulting in unpleasant odors that affect the environment of the entire public area.

[0047] This utility model provides a public area cleaning device. By setting a first cleaning structure 220 and a second cleaning structure 230, it can not only clean the area under the urinal, but also clean the urinal itself, solving the problem of manual cleaning of public areas and saving time and effort.

[0048] Preferably, the first cleaning part 221 is made of a flexible material. The connecting rod 210 is provided with a first connecting end 211, and two rotatable grippers 222 are provided on the first connecting end 211. The two sides of the first cleaning part 221 are respectively connected to the two grippers 222. The first cleaning part 221 is provided with a cleaning surface. When the two grippers 222 rotate in opposite directions, the two sides of the first cleaning part 221 unfold in opposite directions, so that the cleaning surface is set as a plane. At this time, the first cleaning part 221 can effectively fit against the inner wall surface of the urinal, realizing the cleaning of the inner wall of the urinal. When the two grippers 222 rotate towards each other, the two sides of the first cleaning part 221 close towards each other, so that the cleaning surface is set in a V shape. The opening and closing angle of the V-shaped cleaning surface is changed according to the angle of the two sides of the first cleaning part 221 closing towards each other, so as to match the different thicknesses of the urinal edge and realize the cleaning of the urinal edge.

[0049] More preferably, the first connecting end 211 of the connecting rod 210 is also provided with at least one first cleaning liquid spray nozzle 212, and the spray direction of the first cleaning liquid spray nozzle 212 is towards the first cleaning part 221. The first cleaning part 221 is absorbent and can effectively lock the cleaning liquid sprayed from the first cleaning liquid spray nozzle 212, thereby improving the cleaning effect of the inner wall and edge of the urinal.

[0050] It is worth mentioning that after the inner wall and edges of the urinal are cleaned, the water automatically flowing out from inside the urinal not only washes away the residual cleaning solution on the inner wall, but also rinses away the residual cleaning solution in the first cleaning section 221. After cleaning, the first cleaning section 221 is free of cleaning solution. At this point, the first cleaning section 221 can wipe away residual cleaning solution on areas of the urinal that cannot be cleaned by the automatic water flow, as well as on the edges of the urinal, ensuring the overall cleanliness of the urinal. Furthermore, since the first cleaning section 221 is absorbent, to ensure its dryness and cleanliness, the two grippers 222 can rotate continuously in opposite directions, squeezing the first cleaning section 221 to expel water and achieve a drying effect.

[0051] Therefore, in this embodiment, by setting two grippers 222, not only can the shape of the first cleaning part 221 be changed to match the inner wall and edge of the urinal, but the cleaning liquid or water inside the first cleaning part 221 can also be effectively squeezed out, ensuring that the first cleaning part 221 is dry and clean, and realizing the health and environmental protection of the first cleaning part 221.

[0052] It is further pointed out that there are two first cleaning fluid spray nozzles 212, and the two first cleaning fluid spray nozzles 212 are located on both sides of the first connecting end 211. The plane where the two grippers 222 are located is perpendicular to the plane where the line connecting the two first cleaning fluid spray nozzles 212 is located and along the axial direction of the connecting rod 210.

[0053] Preferably, the second cleaning structure 230 includes a housing 231 connected to the second connecting end 213 of the connecting rod 210, and a slot 2311 and a stepped surface 2312 are provided on the side of the housing 231 facing away from the first cleaning structure 220. A spiral soft rubber scraper 232 is provided at the position corresponding to the slot 2311, and a rotating hard bristle brush 233 is provided at the position corresponding to the stepped surface 2312. The spiral soft rubber scraper 232 and the rotating hard bristle brush 233 constitute the second cleaning part.

[0054] It is worth mentioning that the spiral soft rubber scraper 232 can remove residual dirt and water stains from the area below the urinal, while the rotating hard brush 233 can effectively remove dried and stubborn stains from the area below the urinal. Furthermore, the stepped surface 2312 effectively eliminates the height difference between the spiral soft rubber scraper 232 and the rotating hard brush 233, allowing both to contact the ground simultaneously, thereby improving the cleaning effect.

[0055] Furthermore, the spiral soft rubber scraper 232 can rotate circumferentially in a vertical plane, and the rotating hard bristle brush 233 can rotate circumferentially in a horizontal plane. The axial direction of the spiral soft rubber scraper 232 is perpendicular to the axial direction of the rotating hard bristle brush 233.

[0056] It is worth mentioning that there are two spiral soft rubber scrapers 232, with their axes parallel to each other and arranged side by side. There are also two rotating hard bristle brushes 233, with their axes parallel to each other and arranged side by side. The arc surfaces formed by the outermost edges of the two spiral soft rubber scrapers 232 intersect, and the protrusion on one spiral soft rubber scraper 232 corresponds to the concave part on the other spiral soft rubber scraper 232. The arc surfaces formed by the outermost edges of the two rotating hard bristle brushes 233 are tangent to each other.

[0057] Preferably, the rotating stiff brush 233 is provided with a second cleaning liquid spray nozzle 234, and the spray direction of the second cleaning liquid spray nozzle 234 is consistent with the opening direction of the slot 2311. The cleaning liquid can be sprayed onto the floor below the urinal through the second cleaning liquid spray nozzle 234, thereby further improving the floor cleaning effect.

[0058] Preferably, the housing 231 is also provided with a water inlet 2313, and the water inlet 2313 and the slot 2311 are located on the same side of the housing 231. The water inlet 2313 can absorb the residual water on the ground after cleaning, prevent the ground from being slippery, reduce secondary pollution, and ensure that the ground is clean and tidy.

[0059] Preferably, the support 100 is provided with a liquid storage tank 120 and two side-by-side boxes, which are a clean water tank 130 and a wastewater tank 140, respectively. The liquid storage tank 120 is used to store cleaning fluid. The clean water tank 130 is connected to the first cleaning fluid spray port 212 and the second cleaning fluid spray port 234 through conduits. The wastewater tank 140 is connected to the suction port 2313 through a conduit and a vacuum pump. The liquid storage tank 120 is connected to the first cleaning fluid spray port 212 and the second cleaning fluid spray port 234 through conduits.

[0060] It is worth mentioning that, since the clean water tank 130 and the liquid storage tank 120 are respectively connected to the first cleaning spray nozzle and the second cleaning liquid spray nozzle 234, two outlets are provided in the first cleaning liquid spray nozzle 212 and the second cleaning liquid spray nozzle 234. One outlet is used to dispense clean water, and the other outlet is used to dispense cleaning liquid. This allows the clean water and cleaning liquid to mix thoroughly in the first cleaning liquid spray nozzle 212 and the second cleaning liquid spray nozzle 234, thereby improving the cleaning effect on the floor, inner wall and edge of the area below the urinal.

[0061] In addition, the clean water tank 130, the wastewater tank 140, and the liquid storage tank 120 are all detachably connected to the support 100, which facilitates the replenishment of the clean water tank 130, the emptying of the wastewater tank 140, and the replenishment of the liquid storage tank 120.

[0062] Furthermore, by using a vacuum pump in conjunction with a conduit, a negative pressure is created at the water intake 2313, thereby drawing residual water from the ground into the wastewater tank 140 through the conduit, preventing the ground from becoming slippery and reducing secondary pollution.

[0063] Preferably, the robotic arm 200 includes a first telescopic arm 240 and a second telescopic arm 250, and the first telescopic arm 240 is connected to the connector 110, the first telescopic arm 240 is connected to the second telescopic arm 250, and the second telescopic arm 250 is connected to the connecting rod 210 through a movable joint 260. The movable joint 260 changes the included angle between the first telescopic arm 240 and the ground, between the first telescopic arm 240 and the second telescopic arm 250, and between the second telescopic arm 250 and the connecting rod 210.

[0064] It is worth mentioning that the first telescopic arm 240 and the second telescopic arm 250 are equipped with push-pull hydraulic rods to adapt to different heights between the track and the ground, as well as the height between the urinal and the ground. In addition, the first telescopic arm 240 and the second telescopic arm 250 are covered with rubber corrugated tubes to accommodate different telescopic lengths of the first telescopic arm 240 and the second telescopic arm 250.

[0065] Preferably, a 360° fisheye sensor 270 is installed on the connecting rod 210, and the 360° fisheye sensor 270 has built-in infrared sensor and millimeter-wave radar to accurately determine the position of the urinal and realize directional cleaning. Moreover, the millimeter-wave radar assists the infrared sensor to filter interference signals such as water mist, reflection or foreign objects blocking the infrared sensor, avoids false triggering of the infrared sensor, and ensures that the cleaning equipment starts the cleaning task only when no one is using the urinal.

[0066] Preferably, the cleaning equipment includes:

[0067] The base frame 300 is installed on a wall or the ground, and a mounting groove 310 is provided along the length of the base frame 300;

[0068] The drive structure 400 includes a drive motor 410 connected to the bottom of the mounting groove 310, and the output end of the drive motor 410 is connected to a lead screw 420 to form the track. The support 100 is screwed onto the lead screw 420. The drive motor 410 drives the lead screw 420 to rotate, so that the support 100 reciprocates along the length direction of the lead screw 420.

[0069] More preferably, the base frame 300 is provided with multiple infrared sensors along its length, and the position of each infrared sensor corresponds to the position of the urinal above. The infrared sensors record the flow rate of people using the urinal in front, so as to intelligently determine the cleaning time and frequency. In addition, signals can also be sent to the cleaning equipment to avoid crowds.

[0070] Preferably, a cleaning tank 500 is provided at the end of the base frame 300 away from the drive motor 410, and a cleaning chamber 510 is provided inside the cleaning tank 500.
