[0045] The present application provides a smart scrubber with deodorization function. The scrubber can oxidize the dirt in the sewage container by ozone to avoid the emission of odor, without affecting the user experience and without the need to frequently disassemble and clean the sewage container, saving time and effort.

[0046] Specifically, in an embodiment of the present application, as shown in Figures 1-3 The smart scrubber with deodorization function includes a body 1, a brush roller 2, a scraper 3, a dirt treatment box 12 and a drive wheel 4.

[0047] In the embodiment, as shown in Figures 1-3 The brush roller 2 is arranged at the bottom of the body 1 and can contact the ground to brush the ground. A sprayer 9 is arranged on the brush roller 2. The sprayer 9 is connected to a water pump (not shown in the figure) in a water tank (not shown in the figure) through a water pipe. In this way, water can be sprayed on the brush roller 2 by the sprayer 9 to wet-sweep the ground, i.e., to wash the ground.

[0048] In the embodiment, as shown in Figures 1-3 The scraper 3 is located behind the brush roller 2 in the forward direction of the scrubber. The lower surface of the scraper 3 contacts the ground. During the forward movement of the scrubber, the scraper 3 can scrape the dirt on the ground and concentrate the dirt in one place. A dirt suction pump 10 is arranged on the scraper 3. The dirt suction pump 10 is connected to the dirt treatment box 12 through a dirt discharge pipe 11. The dirt suction pump 10 can suck the dirt scraped by the scraper 3 and send the dirt into the dirt treatment box 12 through the dirt discharge pipe 11 for concentrated treatment.

[0049] In the embodiment, as shown in Figures 1-4As shown, the dirt treatment box 12 is used to concentrate the treatment of dirt, which includes sewage and solid small garbage. In this embodiment, ozone is introduced into the dirt treatment box 12, and the strong oxidation performance of ozone is used to oxidize the dirt, so that the dirt does not produce odor. At the same time, ozone can also oxidize the odor accumulated in the dirt treatment box 12, so that the air in the dirt treatment box 12 is odorless. In this way, the sewage container does not need to be frequently disassembled and washed, which saves time and effort and does not affect the user experience.

[0050] In this embodiment, as shown in the figure, Figures 1-3 The driving wheel 4 is arranged below the machine body 1, and a hub motor 5 is arranged in the driving wheel 4. The driving wheel 4 is driven to rotate by the hub motor 5, so as to realize the forward movement or backward movement of the scrubber.

[0051] In this embodiment, as shown in the figure, Figures 1-3 The end of the machine body 1 away from the driving wheel 4 is provided with a steering wheel 6 for steering during the forward movement or backward movement of the scrubber. Further, an elastic suspension arm 8 is fixedly arranged at the end of the machine body 1 away from the driving wheel 4. The elastic suspension arm 8 is made of an elastic material, such as spring steel. One end of the elastic suspension arm 8 is fixedly connected to the machine body 1, and the other end is suspended. A steering motor 7 is vertically fixedly arranged at the suspended end. The lower end output shaft of the steering motor 7 is connected to the steering wheel 6. The steering wheel 6 is rotated around a vertical line by controlling the rotation of the steering motor 7 to realize the steering of the scrubber. In this way, the elastic suspension arm 8 can realize the limited movement of the steering wheel 6 in the vertical direction, so as to ensure the stable movement of the scrubber when the steering wheel 6 passes through the uneven road surface.

[0052] In this embodiment, as shown in the figure, Figures 1-3 The dirt treatment box 12 is detachably fixedly connected to the machine body 1. In this way, the dirt treatment box 12 is convenient to disassemble and assemble.

[0053] In this embodiment, as shown in the figure, Figures 1-3 The machine body 1 is further provided with an ozone generator 19 and a voice control system. The ozone generator 19 is communicated with the dirt treatment box 12 through a pipeline, as shown in the figures, Figure 3 and Figure 4 The pipeline is an air inlet pipe 18. The ozone generated by the ozone generator 19 is sent into the dirt treatment box 12 through the air inlet pipe 18, so as to oxidize and deodorize the dirt in the dirt treatment box 12 by ozone.

[0054] Further, in this embodiment, as shown in the figures, Figure 2 and Figure 3 The machine body 1 is further provided with a gas tank 22 for storing gas. The gas does not react with ozone, such as nitrogen or other inert gases that do not react with ozone. The gas tank 22 is communicated with the pipeline, as shown in the figures, Figure 3 and Figure 4As shown, the gas tank 22 is communicated with the gas inlet pipe 18 through the gas inlet pipe 20.

[0055] In the embodiment, the sewage treatment tank 12 is provided with a stirrer, which stirs the sewage so that the ozone is fully mixed with the sewage and the oxidation treatment efficiency of the sewage is accelerated.

[0056] Specifically, in the embodiment, as shown in the figure, Figure 4 As shown, the stirrer comprises a gas disc 13 and a gas inlet manifold 17, the gas disc 13 is horizontally arranged at the bottom of the sewage treatment tank 12, the gas disc 13 is hollow inside and can store a certain amount of gas, as shown in the figure, Figure 5 As shown, a plurality of stirring pipes 30 are vertically arranged on the gas disc 13, when the gas disc 13 rotates around the vertical axis, the stirring pipes 30 can be driven to rotate to stir the sewage, it should be noted that the stirring pipes 30 can not only stir the sewage and solid impurities in the sewage treatment tank 12, but also can stir the air in the sewage treatment tank 12, so as to accelerate the oxidation and deodorization of the ozone to the odor in the air.

[0057] In the embodiment, as shown in the figure, Figure 4 As shown, the stirring pipes 30 are communicated with the inside of the gas disc 13, and the gas in the gas disc 13 can enter each stirring pipe 30.

[0058] In the embodiment, as shown in the figure, Figure 4 As shown, the gas disc 13 is provided with a transmission pipe 14 at the center axis, as shown in the figure, Figure 4 As shown, the transmission pipe 14 and the gas disc 13 are coaxially arranged, the upper end of the transmission pipe 14 is fixedly connected with the gas disc 13, the lower end penetrates the sewage treatment tank 12 and extends out of the sewage treatment tank 12 and is drivingly connected with a rotating motor 16, the rotating motor 16 is fixedly arranged on the machine body 1, and the specific transmission form can be gear transmission, as shown in the figure, Figure 4 As shown, the output shaft of the rotating motor 16 and the transmission pipe 14 are both provided with gears 15, the two gears 15 are engaged, the rotating motor 16 drives the transmission pipe 14 to rotate through the gears 15, the transmission pipe 14 drives the gas disc 13 to rotate synchronously, and then drives the stirring pipes 30 to rotate to stir the sewage and odor in the sewage treatment tank 12.

[0059] In the embodiment, as shown in the figure, Figure 4 As shown, the transmission pipe 14 is connected with the sewage treatment tank 12 in rolling sealing, which avoids leakage of the sewage in the sewage treatment tank 12 from the connection between the sewage treatment tank 12 and the transmission pipe 14.

[0060] In the embodiment, as shown in the figure, Figure 4As shown, the intake manifold 17 is arranged in the transmission pipe 14 and communicates with the interior of the air disc 13. The intake manifold 17 and the transmission pipe 14 are coaxially arranged, and the upper end of the intake manifold 17 is connected to the air disc 13 in a rolling seal. With this design, when the air disc 13 rotates around the transmission pipe 14, the intake manifold 17 can be fixed and not rotated, while ensuring the sealing of the connection between the intake manifold 17 and the air disc 13 to prevent air leakage.

[0061] In this embodiment, if Figure 3 and Figure 4 As shown, the intake pipe 1 18 and the intake pipe 2 20 are connected to the lower end of the intake manifold 17. The intake pipe 1 18 is used to transport ozone into the intake manifold 17, and the intake pipe 2 20 is used to transport nitrogen or other gases that do not react with ozone into the intake manifold 17. The gas in the intake manifold 17 is set to be a mixture of ozone and nitrogen or other gases. The mixed gas enters each stirring tube 30 through the gas disk 13, as shown in FIG. Figure 4 As shown, the stirring tube 30 is provided with a plurality of jet holes 31 along its length direction. The mixed gas in the stirring tube 30 is ejected from the jet holes 31 and injected into the sewage and air in the sewage treatment box 12. Then, the ozone oxidizes and deodorizes the odor in the sewage and the air to prevent the sewage from generating odor later.

[0062] In this embodiment, since the volume of the sewage treatment box 12 is not large, it is not necessary to introduce too much ozone into the sewage treatment box 12. Introducing too much ozone may cause ozone leakage and pollute the air, endangering the safety of the cleaning staff operating the floor scrubber. However, at this time, due to the small amount of ozone, the ozone gas may not be able to overcome the pressure of the sewage and cannot emerge from the jet hole 31. Instead, the sewage enters the stirring tube 30 and the air disk 13 through the jet hole 31, and finally causes the sewage in the sewage treatment box 12 to enter the stirring tube 30, the air disk 13, and the air intake manifold 17, blocking the stirring tube 30 and / or the air disk 13 and / or the air intake manifold 17 and causing the agitator to fail. Based on the above considerations, a gas tank 22 is added, and nitrogen and other gases that do not react with ozone are mixed into the ozone gas through the gas tank 22, thereby increasing the gas pressure, so that the mixed gas of ozone and nitrogen overcomes the water pressure and is smoothly ejected from the jet hole 31, so that the ozone can smoothly contact with the sewage and odor.

[0063] In this embodiment, if Figure 4 、 Figure 6 and Figure 7As shown, the agitator further comprises a mounting plate 28, a plug column 29 and an air inlet pipe four 24, the mounting plate 28 is arranged right above the air disc 13 and is parallel to the air disc 13; the number of the plug columns 29 is opposite to the number of the agitator pipes 30, one plug column 29 is inserted into each agitator pipe 30, the lower end of the plug column 29 is connected with the agitator pipe 30 through vertical sliding seal insertion, in this way, on the one hand, the upper end of the agitator pipe 30 can avoid gas leakage, on the other hand, the plug column 29 can block the air injection hole 31 when it is lowered, thus avoiding that when there is no mixed gas in the air inlet manifold 17, the sewage in the sewage treatment tank 12 enters the agitator to block the agitator pipe 30 and / or the air disc 13 and / or the air inlet manifold 17 and make the agitator invalid, the upper end of the plug column 29 is fixedly connected with the mounting plate 28, and the mounting plate 28 is driven to rotate by the agitator pipe 30 and the plug column 29 when the air disc 13 rotates.

[0064] In the embodiment, when the ozone generator 19 does not work and the gas tank 22 does not supply gas into the air inlet manifold 17, in order to prevent the sewage in the sewage treatment tank 12 from entering the agitator through the air injection hole 31 to block the agitator pipe 30 and / or the air disc 13 and / or the air inlet manifold 17 and make the agitator invalid, the plug column 29 is inserted into the agitator pipe 30, and the lower end of the plug column 29 is flush with the lower end of the agitator pipe 30, thus blocking all the air injection holes 31 on the agitator pipe 30, when the ozone generator 19 starts to generate ozone and the gas tank 22 opens to inject gas into the air inlet manifold 17, the plug column 29 rises to gradually open all the air injection holes 31, in particular, when the gas pressure of the mixed gas in the agitator pipe 30 is enough to prevent the sewage from entering the agitator pipe 30 through the air injection hole 31, the plug column 29 starts to rise.

[0065] In the embodiment, as shown in the figure, Figure 4 The air inlet pipe four 24 is vertically rotatably mounted on the central axis of the mounting plate 28, the air inlet pipe four 24 is coaxial with the mounting plate 28, in this way, the mounting plate 28 can ensure that the air inlet pipe four 24 does not move when it rotates, the air inlet pipe four 24 is rotatably connected with the mounting plate 28 through the limiting plate 25, in this way, the air inlet pipe four 24 can avoid axial movement on the mounting plate 28, the lower end of the air inlet pipe four 24 is flush with the upper end of the agitator pipe 30, the upper end of the air inlet pipe four 24 is communicated with the gas tank 22 through the air inlet pipe three 23, the lower end of the air inlet pipe four 24 is fixedly provided with an air bag 26, the air bag 26 is made of elastic material which can prevent ozone oxidation, when it is needed to make the plug column 29 rise, the air bag 26 is inflated by the gas tank 22, after the air bag 26 is expanded by the gas, its volume gradually increases, since the air bag 26 is located in the sewage, as the air bag 26 gradually expands, the mounting plate 28 is driven to move upward by the buoyancy of the air bag 26 to gradually open the air injection holes 31, when it is needed to make the plug column 29 descend, the gas in the air bag 26 is released, the volume of the air bag 26 decreases, and the buoyancy generated by the air bag 26 also decreases, finally, the plug column 29 descends and resets under the gravity of itself and the mounting plate 28.

[0066] In the embodiment, as shown in the figure, Figure 3 The air inlet pipe three 23 and the air inlet pipe two 20 are both communicated with the gas tank 22 through the control valve 21, the control valve 21 can control the gas in the gas tank 22 to enter the air inlet pipe two 20 and the air inlet pipe three 23, and control the gas in the air bag 26 to be discharged by the control valve 21 through the air inlet pipe three 23.

[0067] Further, in the embodiment, as shown in the figure, Figure 3 The air volume adjusting valve 38 is arranged on the air inlet pipe two 20, which is used to adjust the air flow entering the stirring pipe 30. Specifically, as the plug column 29 gradually rises, more and more air injection holes 31 are not blocked by the plug column 29. In order to avoid sewage entering the stirring pipe 30 through the air injection hole 31, the air volume adjusting valve 38 should adjust the air flow in the air inlet pipe two 20 to be larger and larger.

[0068] In the embodiment, in order to ensure that the plug column 29 can be reliably reset by itself after the gas in the air bag 26 is discharged by the control valve 21, as shown in the figure, Figure 4 The inner wall of the sewage treatment box 12 is provided with a plurality of spring plates 27 which are centrally symmetrically distributed. One end of the spring plate 27 is fixedly connected with the inner wall of the sewage treatment box 12, and the other end is elastically pressed on the mounting plate 28 and can be slidably connected with the mounting plate 28. The mounting plate 28 pushes the spring plate 27 to bend, and after the gas in the air bag 26 is discharged, the bent spring plate 27 pushes the mounting plate 28 to descend during the resetting process, so as to reset the plug column 29. On the other hand, the plurality of spring plates 27 which are centrally symmetrically distributed can also make the mounting plate 28 keep stable rotation without deflection.

[0069] In the embodiment, as shown in the figure, Figure 4 The sewage treatment box 12 has a box cover 37, which is designed to facilitate the placement of the stirrer in the sewage treatment box 12.

[0070] In the embodiment, as shown in the figure, Figure 3 The outer wall of the sewage treatment box 12 is fixedly provided with an air outlet pipe 36. The gas in the sewage treatment box 12 which has been deodorized by ozone oxidation can be discharged from the air outlet pipe 36. In addition, other parts in the sewage treatment box 12 are all isolated from the outside world, and there is no gas leakage.

[0071] Further, in order to avoid that the ozone in the sewage treatment box 12 pollutes the environment and endangers the safety of the operator of the scrubber, as shown in the figure, Figure 3 The air outlet pipe 36 is provided with an electric heater 35. The gas which needs to be discharged into the air outlet pipe 36 is heated by the electric heater 35, so that the ozone in the gas is decomposed, thereby achieving the purpose of preventing ozone leakage.

[0072] In the embodiment, the voice control system is used to pick up external voice signals and control the operation of the scrubber, so as to realize voice control of the scrubber.

[0073] Specifically, the voice control system comprises a voice collection device, a voice pre-processing device, a voice training device, a voice recognition device, a voice prompting device and an output control device. The voice collection device can complete functions such as voice signal conditioning and voice signal collection, and converts the voice control signals emitted by the worker into a voice pulse sequence. The voice collection device comprises a microphone 34, a sound / electricity conversion module and a signal conditioning module. The voice pre-processing device filters out interference signals, extracts voice feature vectors and quantizes the extracted voice feature vectors into standard voice feature vectors. Therefore, the device comprises a voice pre-processing module, a feature extraction module and a vector quantization module. The voice training device performs probability statistics on the standard voice feature vectors extracted through multiple collections, extracts the best voice feature standard vector of the speaker, prevents the inaccuracy of the extracted feature parameters caused by the mood of the speaker, the environment and other factors from affecting the voice recognition effect, and realizes accurate extraction of the voice feature standard vector through a hidden Markov model (HMM model). The voice recognition device compares the re-collected standard voice feature vectors with the voice models in the voice template library, judges the current voice command function, and comprises a vector comparison module and a parameter evaluation module. The voice template library stores the best standard voice feature vectors after training. The voice prompting device prompts the user to perform related operations or explains the current completed function according to the voice recognition result, and comprises a calling prompt voice resource file module, a D / A conversion module and a signal amplification module. The output control device outputs corresponding control signals according to the voice recognition result, realizes voice control functions such as forward movement, backward movement, turning, starting scrubbing, stopping scrubbing and ozone disinfection of the scrubber, and comprises a signal driving module and an output controller.

[0074] Further, in the embodiment, the scrubber further comprises a visual control system for picking up external gesture signals and controlling the operation of the scrubber, so as to realize gesture control of the scrubber and facilitate the worker to flexibly select voice control or gesture control of the scrubber according to actual needs.

[0075] Specifically, the visual control system comprises a camera 33, a visual processor and an image collection card. The camera 33 adopts a CCD camera lens. The camera 33 converts the gestures of the worker captured into image signals and transmits the image signals to the image collection card. The image collection card converts the image signals into digital signals according to pixel distribution, brightness and color information. The visual processor performs various operations on the signals to extract gesture features such as the moving path of the gesture, and then controls the scrubber to execute the desired control instructions.

[0076] In the embodiment, in order to facilitate disassembly and maintenance of the voice control system and the visual control system, the voice control system and the visual control system are integrated into the central control box 32, and the central control box 32 is detachably and fixedly installed on the dirt treatment box 12, as shown in FIG. 1.
