Detailed Implementation

[0037] The core of this utility model is to provide a bathroom cleaning device that can quickly clean and dry bathroom floors at low cost.

[0038] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of a toilet cleaning device provided in an embodiment of this application; Figure 2 This is a schematic diagram of the airflow guiding duct provided in the embodiments of this application; Figure 3 This is a cross-sectional structural diagram of the toilet cleaning equipment provided in an embodiment of this application.

[0040] In one specific embodiment of this application, the toilet cleaning device may include:

[0041] The equipment housing 1 has an air inlet 11 at the top and an air outlet 12 at the bottom;

[0042] The fan 2, heating resistor 3 and controller are installed inside the equipment housing 1, wherein the heating resistor 3 wire is located between the fan 2 and the air outlet 12;

[0043] A ground water stain detector installed on the equipment housing 1;

[0044] The controller is used to start the fan 2 and heating resistor 3 when the ground water stain detector detects water stains on the ground.

[0045] A power supply device installed inside the equipment housing 1 to supply power to the fan 2, heating resistor 3, image acquisition unit and controller.

[0046] like Figure 1As shown, the equipment housing 1 in this application is generally a narrow rectangular structure; the air inlet 11 can be located at the top of the housing, while the air outlet 12 is located on the bottom side of the larger side of the equipment housing 1. Furthermore, both the air inlet 11 and the air outlet 12 on the equipment housing 1 are perforated structures with several through holes. Thus, when the fan 2 inside the equipment housing 1 starts working, it drives airflow from the air inlet 11 into the equipment housing 1, and after passing through the fan 2, it flows out from the air outlet 12 and blows towards the ground. In addition, a heating resistor 3 is further provided between the fan 2 and the air outlet 12. When the airflow from the fan 2 towards the air outlet 12 passes through the heated resistor 3, the airflow forms a hot airflow, which, when blown onto water stains on the ground, can more quickly dry and clean the water stains.

[0047] The ground water stain detector in this application can be implemented in a variety of different ways.

[0048] In an optional embodiment of this application, the floor water stain detector can be a floor image acquisition device. This device should be tilted downwards to acquire images only of the bathroom floor. The acquired floor images can be directly uploaded to a host computer via a controller. The host computer can use a pre-trained image recognition model to identify whether there are water stains in the floor images, and then issue a cleaning command to the controller. Upon receiving the command, the controller can activate the fan 2 and the heating resistor 3. The image recognition model can be trained based on the characteristic that areas with and without water stains on the floor have different light reflection effects. Furthermore, the image recognition model can also be directly integrated into the controller, which uses this pre-trained model to identify whether there are water stains on the floor.

[0049] Of course, in practical applications, it is also possible to directly display the ground images collected by the ground image acquisition device on the host computer, and let the cleaning workers directly judge whether there are water stains to determine whether cleaning is required. All of these can achieve the technical solution of this application.

[0050] In another optional embodiment of this application, the ground water stain detector can also employ a laser scanning device. The laser scanning device can scan and output laser light onto the ground. The reflectivity of the light is different on a surface with water stains and a surface without water stains, thus the presence of water stains can be determined based on the intensity of the reflected light received by the receiver in the laser scanning device. Other implementations of the ground water stain detector are also possible, but are not listed here.

[0051] In addition, such as Figure 2As shown, multiple sets of fans 2 and heating resistors 3 can be provided in this application; and each fan 2 is connected in parallel to each other and electrically connected to the power supply device; each heating resistor 3 is connected in parallel to each other and electrically connected to the power supply device.

[0052] like Figure 2 As shown, multiple fans 2 can be arranged side-by-side on the same horizontal plane, and each heating resistor 3 can include a resistor frame formed by multiple resistor strips connected at intervals; the heating resistors 3 are arranged sequentially along the airflow direction of the fans 2. In practical applications, the fans 2 are connected in parallel, so each fan 2 can be started and stopped independently, and the heating resistors 3 are also connected in parallel, so each heating resistor 3 can also be started and stopped independently. Therefore, in practical applications, different numbers of fans 2 and different numbers of heating resistors 3 can be started according to actual needs.

[0053] In addition, a human-machine interface can also be set on the equipment housing 1. Specifically, it can be an interface with multiple physical buttons or an interface with a touch screen, so that even when the floor water stain detector of the bathroom cleaning equipment is not detecting floor water stains, it can still receive human operation commands to start the air blowing cleaning operation.

[0054] In addition, the power supply device inside the device housing 1 can be a rechargeable battery, and a wireless charger electrically connected to the power supply device can also be installed on the device housing 1.

[0055] In practical applications, a corresponding wireless charging power supply can be installed on the bathroom wall. When the wireless charger on the device box 1 is attached to the wireless charging power supply on the wall, it can start charging the power supply device.

[0056] As described above, the equipment housing 1 in this application is generally a flat cuboid structure, with the air inlet 11 located on the uppermost plane of the equipment housing 1 and the air outlet 12 located on one side of the equipment housing 1. That is to say, the air inlet 11 and the air outlet 12 are located on mutually perpendicular surfaces of the equipment housing 1, which results in a 90-degree deflection in the airflow path inside the equipment housing 1. If the airflow directly generates a 90-degree angle inside the equipment housing 1, it will cause greater resistance to the airflow, which is not conducive to the airflow flowing out from the air outlet 12.

[0057] Therefore, such as Figure 2 and Figure 3 As shown, in an optional embodiment of this application, the equipment housing 1 of the toilet cleaning device may further include:

[0058] A guide air duct is installed inside the equipment housing 1, with the top port connected to the edge of the air inlet 11 and the bottom port connected to the air outlet 12.

[0059] The airflow duct has a J-shaped structure along the airflow direction; the top port of the airflow duct is provided with a first airflow guiding structure 41 that has an outward convex curved surface relative to the inner side of the airflow duct; the upper edge of the bottom port of the airflow duct is provided with a second airflow guiding structure 42 that has an inward concave curved surface relative to the inner side of the airflow duct; and the lower edge of the bottom port of the airflow duct is provided with a third airflow guiding structure 43 that has an outward convex curved surface relative to the inner side of the airflow duct.

[0060] The fan 2 and the heating device are both located inside the air duct; the controller and the power supply device are located outside the air duct.

[0061] In this embodiment, a guide air duct connecting the air inlet 11 and the air outlet 12 is provided inside the equipment housing 1. The guide air duct extends from the air inlet 11 to the air outlet 12 in a roughly J-shaped structure. That is to say, the guide air duct in this embodiment includes a curved section, so that after the airflow flows downward from the air inlet 11 in a roughly vertical direction through the guide air duct, it can smoothly turn through the curved section and finally be output from the air outlet 12. This reduces the airflow resistance and ensures that the airflow blown by the fan 2 is smoothly and effectively output from the air outlet 12 to the greatest extent. This allows the fan 2 to output a faster airflow from the air outlet 12 under the same working power conditions, which improves the cleaning rate of the cleaning equipment.

[0062] like Figure 2 and Figure 3 As shown, in order to ensure that the airflow at the air outlet 12 flows smoothly into the guide duct, in this embodiment, a first guide structure 41 with an outwardly convex curved surface can be further provided at the top port of the guide duct (i.e. the port connected to the edge of the air outlet 12), which means that the diameter at the top inlet of the guide duct gradually narrows, so that the airflow can flow into the guide duct more quickly.

[0063] like Figure 2 and Figure 3As shown, a second guide structure 42 and a third guide structure 43 are further provided on the bottom port of the air duct that connects to the edge of the air outlet 12. The second guide structure 42 is located at the upper edge of the bottom port, while the third guide structure 43 is located at the lower edge of the bottom port. The second guide structure 42 has an inwardly concave curved surface relative to the inner side of the air duct, while the third guide structure 43 has an outwardly convex curved surface relative to the inner side of the air duct. This makes the second guide structure 42 and the third guide structure 43 form a slightly downward air outlet at the bottom port of the air duct. This allows the airflow output from the air outlet 12 to blow slightly downward to a certain extent, so that the airflow blows towards the bathroom floor to the maximum extent, rather than towards the space above the floor, thereby further improving the cleaning effect of the equipment.

[0064] Furthermore, considering that if the toilet cleaning equipment is activated while the toilet is in use, it may provide a poor user experience, this application can also equip the toilet cleaning equipment with an infrared detector to detect whether there is anyone in the toilet. If there is someone, the toilet cleaning equipment will not be activated or will not blow air into the area where the person is; the equipment will only be activated after there is no one in the toilet.

[0065] In addition, the toilet cleaning equipment in this application may also include an aromatherapy container installed inside the equipment housing 1. The aromatherapy container may be a drawer-type structure that can be pulled out from the equipment housing 1 or pushed into the equipment housing 1. When the aromatherapy container is pushed into the equipment housing 1, it may be located between the fan 2 and the air outlet 12; specifically, it may be installed inside the air duct.

[0066] Based on any of the above embodiments, in another optional embodiment of this application, the toilet cleaning device may further include:

[0067] The equipment housing 1 is also equipped with a humidity detector that is connected to the controller;

[0068] When the humidity detector detects that the air humidity data is greater than the humidity threshold, the controller controls the fan 2 and the heating resistor 3 to start working.

[0069] It is understood that the bathroom cleaning device of this application can clean water stains on the bathroom floor. In practical applications, this bathroom cleaning device can be used not only in public restrooms, but also in home bathrooms or hotel room bathrooms. In addition, because the bathroom cleaning device of this application can blow out hot air, it not only cleans water stains on the floor, but also dries moisture in the space.

[0070] Therefore, after a user showers, the bathroom environment is relatively humid. For bathrooms with poor ventilation, maintaining a humid environment for a long time not only creates a poor user experience but also easily breeds bacteria. To address this, this application further includes a humidity detector on the device housing 1. When the humidity detector detects that the bathroom environment is too humid, it can also activate the fan 2 and the heating resistor 3 to start working, thereby maximizing the rapid drying of the bathroom environment.

[0071] In addition, during rainy weather, the humidity detector of the bathroom cleaning equipment can detect excessive humidity in the bathroom and automatically activate the hot air drying function to provide users with a dry bathroom environment, thereby improving the user experience.

[0072] Based on any of the above embodiments, under normal circumstances, if there are water stains on the bathroom floor, simply blowing the water dry will inevitably leave footprints and other stains on the floor. Therefore, in another optional embodiment of this application, the bathroom cleaning device may further include:

[0073] The equipment housing 1 is also equipped with a rag outlet;

[0074] The equipment housing 1 is also equipped with a drive motor, a telescopic rod connected to the drive motor, and a support plate connected to the telescopic rod; a detachable wiping cloth is provided on the support plate.

[0075] In this embodiment, a cloth outlet is provided on the equipment housing 1, allowing the cloth mounted on the support plate to extend or retract from the outlet as the telescopic rod extends and retracts. When the cloth extends from the outlet, the drive motor can drive the telescopic rod to wipe the floor with the cloth. Thus, the bathroom cleaning equipment in this embodiment simultaneously has the functions of wiping and blowing, thereby achieving more effective floor cleaning. Furthermore, when the support plate extends from the outlet, the cloth on the support plate can be replaced.

[0076] In practical applications, the rag outlet can be set on the side of the equipment housing 1 away from the air outlet 12, so that the telescopic rod drives the support plate to extend the rag from one side of the equipment housing 1 for floor cleaning.

[0077] Furthermore, to ensure that the bathroom cleaning equipment can clean a larger area of ​​the bathroom floor to the greatest extent possible, the bathroom cleaning equipment may also include:

[0078] An electric wheel 13 is installed at the bottom of the equipment housing 1 and is connected to the controller.

[0079] The equipment housing 1 is also equipped with an obstacle avoidance device connected to the controller.

[0080] The obstacle avoidance device in this embodiment can be the same obstacle avoidance device used in various walking robots; the controller controls the rolling direction of the electric wheel 13 based on the obstacles detected by the obstacle avoidance device, thereby cleaning the floors of different areas of the bathroom.

[0081] Of course, the toilet cleaning equipment can also move along a fixed path without obstacle avoidance devices. It can be based on the toilet being used, that is, without obstacle avoidance devices on the equipment box 1. The controller controls the electric wheels 13 to drive the equipment to move along a fixed route to clean the toilet floor.

[0082] Based on this, in another optional embodiment of this application, the toilet cleaning device may further include:

[0083] The equipment housing 1 and the electric wheel 13 are connected by a lifting device; the cloth outlet is located on the bottom surface of the equipment housing 1; the telescopic rod can drive the bearing plate to extend and retract in the vertical direction.

[0084] This application places the rag outlet on the bottom surface of the equipment housing 1. When cleaning the bathroom floor, the rag can extend downward from the bottom of the equipment housing 1, so that the rag only needs to be used in the area below the equipment housing 1 when wiping the floor, without occupying too much space outside the equipment housing 1. Moreover, when the rag is wiping the floor, the telescopic rod only needs to apply downward force to the support plate. Compared with the method of the rag extending from the side of the equipment housing 1, the telescopic rod is more likely to apply downward pressure to the support plate, thereby increasing the friction between the rag and the floor and ensuring the cleaning effect of the floor.

[0085] Furthermore, considering that the cloth outlet is located on the bottom surface of the equipment housing 1, which may make cloth replacement difficult, a lifting device can be further installed between the equipment housing 1 and the electric wheel 13. This lifting device can drive the equipment housing 1 to move up and down. When it is necessary to replace the cloth, the lifting device can raise the equipment housing 1 and make the support plate extend from the bottom of the equipment housing 1, thereby easily and simply replacing the cloth.

[0086] In addition, as the lifting device moves the equipment housing 1 up and down, the bathroom cleaning equipment can also clean water stains on the walls at different heights, thereby improving the cleaning function of the equipment.

[0087] In summary, the toilet cleaning equipment of this application can use a floor water stain detector to detect water stains on the toilet floor. Once water stains are detected, the fan can be controlled to draw air through the air inlet and blow it towards the ground through the air outlet. At the same time, the heating resistor heats the airflow blown by the fan towards the air outlet, so that the airflow blown towards the ground is hot air, which can quickly and effectively dry the water stains on the floor. The entire equipment has a simple structure and low implementation cost, and can quickly and effectively clean and dry water stains on the toilet floor, improving the user experience of public toilets at a low cost.
