[0186] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0187] Referring to Figures 1 to 4, a cleaning device provided in one embodiment of this application includes a cleaning unit 1, a spraying unit 21, a wastewater collection unit 4, and a control unit 5. The cleaning unit 1 has a nozzle 11 and a suction port 12. The spraying unit 21 is connected to the nozzle 11 and is used to spray cleaning liquid onto the surface to be cleaned. The wastewater collection unit 4 is connected to the suction port 12 and is used to suck up dirt or wastewater generated during cleaning. Both the spraying unit 21 and the wastewater collection unit 4 are connected to the control unit 5, which is used to control the start and stop of the spraying unit 21 and the wastewater collection unit 4. By integrating the spraying unit 21 and the wastewater collection unit 4, the above-mentioned cleaning device can complete the process of spraying cleaning liquid and sucking up dirt or wastewater on the same device, greatly improving cleaning efficiency. The presence of the control unit 5 allows users to manage the entire cleaning process through a single operation, reducing operation steps and improving user experience. According to different cleaning needs, the control unit 5 can flexibly adjust the spray volume and suction force, enabling the device to better adapt to various working environments and task requirements.

[0188] In one embodiment, the cleaning equipment is a steam cleaner. The cleaning unit 1 includes a cleaning head 1a, which has a nozzle 11 and a suction port 12. The steam cleaner includes a steam generation unit 2 connected to a control unit 5. The steam generation unit 2 includes an electric heater 22 and a spraying unit 21 connected to each other. The electric heater 22 heats the cleaning fluid to provide steam to the spraying unit 21. The control unit 5 controls the start and stop of the steam generation unit 2. The spraying unit 21 can provide cleaning fluid (such as water). When the electric heater 22 heats the cleaning fluid, it generates steam, which is then used to spray steam onto the surface to be cleaned. Traditional steam cleaners suffer from significant heat loss and unstable steam pressure due to the separation of steam generation and spray control. This application centrally manages the start and stop of steam generation, spraying, and wastewater recovery through the control unit 5. Direct linkage between the spraying unit 21 and the electric heater 22 enables rapid steam generation and precise spraying, reducing energy consumption. Meanwhile, by linking the sewage collection unit 4 with the suction port 12 of the cleaning head 1a, dirt and sewage can be recycled to avoid residue and further ensure cleaning efficiency.

[0189] Although the cleaning device can use a heating element to heat the cleaning liquid to provide steam, its heating method is only electric heating, meaning the heat source for generating steam is only electrical energy, resulting in significant energy consumption. Therefore, one embodiment of this application provides a cleaning device that can solve the above problems. The cleaning device provided in this embodiment will be described in detail below.

[0190] One embodiment of the cleaning equipment in this application can be a steam cleaner. The steam cleaner also includes a secondary heating unit 3 connected to a control unit 5. Referring to Figures 1 to 4, the control unit 5 can control the start and stop of the secondary heating unit 3. The secondary heating unit 3 and the electric heater 22 can be connected in parallel. The secondary heating unit 3 and the electric heater 22 are used to heat the cleaning fluid. The heat source of the secondary heating unit 3 is a cleaning heat source. The secondary heating unit 3 will be described in detail below.

[0191] Referring to Figures 1 to 4, in one embodiment, the cleaning device includes a cleaning head 1a, a control unit 5, and a steam generating unit 2, a secondary heating unit 3, and a wastewater collection unit 4, all connected to the control unit 5. As shown in Figure 3, the cleaning head 1a has a nozzle 11 and a suction port 12. As shown in Figures 2 and 4, the steam generating unit 2 includes a spraying unit 21 and an electric heater 22 connected to each other. As shown in Figure 4, the secondary heating unit 3 and the electric heater 22 are connected in parallel, and both are used to heat the cleaning liquid to provide steam for the spraying unit 21; the heat source of the secondary heating unit 3 is a cleaning heat source. The spraying unit 21 is connected to the nozzle 11 and is used to spray steam onto the surface to be cleaned; the wastewater collection unit 4 is connected to the suction port 12 and is used to suck up dirt or wastewater generated during cleaning; the control unit 5 is used to control the start and stop of the steam generating unit 2, the secondary heating unit 3, and the wastewater collection unit 4.

[0192] It is easy to understand that the spraying unit 21 can provide cleaning fluid. When the cleaning fluid is heated by the electric heater 22 and / or the auxiliary heating unit 3, steam is generated, which provides steam to the spraying unit 21, allowing the spraying unit 21 to spray steam onto the surface to be cleaned. In use, the electric heater 22 and the auxiliary heating unit 3 of the steam generation unit 2 can be started and stopped by the control unit 5 according to the cleaning needs and energy conditions. In one embodiment, the control unit 5 can control the electric heater 22 to work and the auxiliary heating unit 3 to not work, so that only electrical energy is used to provide heat to the cleaning fluid to generate steam. Alternatively, the control unit 5 can control the electric heater 22 to work and the auxiliary heating unit 3 to work, so that both electrical energy and clean energy are used to provide energy for steam generation. Or, the control unit 5 can control the electric heater 22 to not work and the auxiliary heating unit 3 to work, so that only clean energy is used to provide energy for steam generation. As can be seen, the cleaning equipment provided in this application, such as a steam cleaner, can not only utilize electricity to provide energy for steam generation, but also utilize a clean heat source to provide energy for steam generation. This can relatively reduce the electricity consumption of steam cleaning operations, which is beneficial for saving electricity and reducing electricity costs. It is worth noting that the auxiliary heating unit 3, which heats the cleaning liquid to generate steam, is a type of clean heat source that does not emit pollutants and can be directly used for production or daily life. Specifically, it is a heat source other than electricity, which can be a renewable heat source, such as solar energy, or a waste heat source. This application does not impose any restrictions on this.

[0193] In the embodiments provided in this application, the clean heat source used by the auxiliary heating unit 3 to heat the cleaning fluid can be solar energy, which is not only readily available but also saves a significant amount of electricity. Calculations show that it can reduce energy consumption by more than 70%. Furthermore, the solar-powered heating device has a relatively simple structure, low cost, and is convenient to use, which helps to improve steam generation efficiency, thereby enhancing cleaning efficiency and cleaning effect.

[0194] In some embodiments, the auxiliary heating unit 3 is used to provide steam, hot water, or hot air to the spraying unit 21. In actual installation, the specific structure of the auxiliary heating unit 3 is not limited. In one embodiment, the auxiliary heating unit 3 is used to provide steam to the spraying unit 21 as an example. In one embodiment, referring to Figure 4, the auxiliary heating unit 3 includes an auxiliary heater 31, which is connected in parallel with an electric heater 22. That is, the inlet and outlet of the auxiliary heater 31 can be connected to pipes that are respectively connected to the inlet and outlet of the electric heater 22.

[0195] It is easy to understand that the auxiliary heater 31 is a heater that can use a clean heat source to heat the cleaning fluid to generate steam. In the embodiment shown in Figure 4, the auxiliary heater 31 is directly connected in parallel with the electric heater 22. In use, the auxiliary heater 31 can use a clean heat source to directly heat the cleaning fluid that is diverted from the pipeline where the electric heater 22 is located. This not only has a simple structure, but also makes full use of the clean heat source, which is beneficial to saving electricity. It is even possible to turn off the electric heater 22 so that the cleaning fluid only passes through the auxiliary heater 31, so that only the clean heat source is used to provide energy for steam generation, thereby saving a large amount of electricity consumption for steam cleaning.

[0196] In one embodiment, the auxiliary heating unit 3 is used to provide hot water to the spraying unit 21.

[0197] In another embodiment provided in this application, please refer to Figure 5 for understanding. The auxiliary heating unit 3 includes a heat exchanger 34 and a water storage tank 33, a first water pump 32, and an auxiliary heater 31 connected in sequence. In one embodiment, the outlet of the water storage tank 33 is connected to the inlet of the first water pump 32 through a pipe. The outlet of the first water pump 32 is connected to the inlet of the auxiliary heater 31 through a pipe. The outlet of the auxiliary heater 31 is connected to the heat medium inlet of the heat exchanger 34 through a pipe. The heat medium outlet of the heat exchanger 34 is connected to the inlet of the water storage tank 33. The heat exchanger 34 and the electric heater 22 are connected in parallel.

[0198] It is easy to understand that the heat from the cleaning heat source may be relatively large. If the auxiliary heater 31 is used directly to heat the cleaning fluid, the temperature of the generated steam under high pressure may be high, for example, it may reach over 600 degrees Celsius. The cleaning equipment, such as the steam cleaner, provided in the above embodiments of this application is equipped with a heat exchanger 34, which connects the auxiliary heater 31 and the heat exchanger 34. The heat exchanger 34 and the electric heater 22 are directly connected in parallel. In use, the auxiliary heater 31 can clean the heat source to heat the cleaning fluid, such as water, pumped by the first water pump 32, and send the heated water into the heat exchanger 34 to exchange heat with the cleaning fluid entering the heat exchanger 34, thereby heating the cleaning fluid, generating steam, and supplying the steam to the cleaning head 1a. In this way, the temperature of the generated steam can be easily controlled within a safe range to reduce safety risks, prevent damage to the items to be cleaned, and ensure personal safety. As can be seen, in actual use, the structural form of the auxiliary heating unit 3 can be selected according to the temperature of the clean heat source. In one embodiment, when the temperature provided by the clean heat source is not particularly high, a simple structure in which the auxiliary heater 31 and the electric heater 22 are directly connected in parallel can be used. When the temperature provided by the clean heat source is particularly high, a safe structure in which the auxiliary heater 31 and the electric heater 22 are connected in parallel via the heat exchanger 34 can be used. Thus, the structural arrangement of the auxiliary heating unit 3 provided in this application embodiment is relatively flexible.

[0199] In embodiments not shown in this application, the auxiliary heating unit 3 and the electric heater 22 can also be connected in series. In one embodiment, when the auxiliary heating unit 3, as shown in FIG. 4, only includes the auxiliary heater 31, the auxiliary heater 31 can be connected in series with the electric heater 22, specifically upstream or downstream of the electric heater 22. When the auxiliary heating unit 3, as shown in FIG. 5, includes the auxiliary heater 31, the first water pump 32, the water storage tank 33, and the heat exchanger 34, the heat exchanger 34 can be connected in series with the electric heater 22, specifically upstream or downstream of the electric heater 22. Thus, the control unit 5 can control both the electric heater 22 and the auxiliary heating unit 3 to operate, so that the cleaning liquid passes through the electric heater 22 and the auxiliary heating unit 3 sequentially, or passes through the auxiliary heating unit 3 and the electric heater 22 sequentially, for dual heating to generate steam; or the control unit 5 can control only one of the electric heater 22 and the auxiliary heating unit 3 to operate. Obviously, the parallel connection of the auxiliary heating unit 3 and the electric heater 22 in the above embodiments of this application is more conducive to the regulation of steam temperature and also more conducive to the compact arrangement of the parts of the cleaning equipment other than the auxiliary heating unit 3.

[0200] In one embodiment, the auxiliary heating unit 3 is used to provide hot air to the spraying unit 21. In some embodiments, the auxiliary heating unit 3 may be connected in parallel or in series with the electric heater 22. The auxiliary heating unit 3 includes an auxiliary heater 31 and a fan. The auxiliary heater 31 is used to heat the air, and the fan is used to blow the hot air around the auxiliary heater 31 to form hot air, thereby heating the incoming cleaning fluid. Alternatively, after cleaning by the cleaning equipment, the auxiliary heating unit 3 provides hot air to the nozzle to dry the cleaned surface, achieving a dry cleaning effect.

[0201] In other embodiments, the auxiliary heating unit 3 may also be a thermal energy storage device, including a housing, a heat charging unit, a heat storage material, and a heat release unit. The heat charging unit includes a heat charging module, and the heat charging module includes a heat charging tube. In some embodiments, the energy source of the thermal energy storage device may be light energy. The heat charging module may include a photothermal charging mechanism (not shown in the figure), which may at least include a light transmission component, such as an optical fiber. The light transmission component is configured to transmit light into the heat charging tube to directly heat the heat charging tube using light energy, and then the heat charging tube transfers the heat energy to the heat storage material for storage. This configuration enables the direct conversion of light energy into heat energy.

[0202] In some embodiments, the energy source of the thermal energy storage device can be electrical energy converted from clean energy. For example, the heat storage module can be a coal-fired power generation unit, a photovoltaic power generation unit, or a wind power generation unit, etc. The power generation unit uses clean energy to convert it into electrical energy, and generates heat through electrical energy, thereby storing the heat in the thermal storage material. Understandably, in some embodiments, the auxiliary heating unit 3 may not be provided. After the cleaning liquid is heated by the electric heater 22, steam can be generated, which can provide steam for the spraying unit 21. In actual installation, the structure of the cleaning head 1a is not limited. In one embodiment, as shown in FIG3, the cleaning head 1a may have a nozzle 11 and a suction port 12 arranged circumferentially around the outer side of the nozzle 11, which is beneficial to improve the cleaning effect and cleaning efficiency.

[0203] In actual installation, the structure of the spray unit 21 is not limited. In one embodiment, as shown in FIG4, the spray unit 21 may include a liquid storage tank 2101 and a second water pump 2102 connected to each other. In one embodiment, the liquid storage tank 2101 can be used to store cleaning fluid, such as water. The outlet of the liquid storage tank 2101 can be connected to the inlet of the second water pump 2102 through a pipe. The outlet of the second water pump 2102 can be connected to the inlet of the electric heater 22. The outlet of the electric heater 22 can be connected to the nozzle 11 of the cleaning head 1a. The second water pump 2102 can be an electromagnetic pump, which can reliably and stably supply cleaning fluid to the electric heater 22. The second water pump 2102 can be connected to the control unit 5. The control unit 5 can control the start and stop of the steam generation unit 2 by controlling the start and stop of the second water pump 2102. Thus, the spray unit 21 has a simple structure and can efficiently provide cleaning fluid. When used in conjunction with the electric heater 22 and under the control of the control unit 5, it can greatly improve the efficiency of steam generation in the entire steam generation unit 2, which is beneficial to improving the cleaning effect and cleaning efficiency.

[0204] In actual installation, the structure of the wastewater collection unit 4 is not limited. In one embodiment, as shown in FIG4, the wastewater collection unit 4 may include a wastewater tank 41 and a suction motor 42 connected to each other. In one embodiment, the inlet of the wastewater tank 41 may be connected to the suction port 12 of the cleaning head 1a, and the inlet of the suction motor 42 may be connected to the outlet of the wastewater tank 41. The suction motor 42 may be connected to a control unit 5, and the control unit 5 can control the start and stop of the wastewater collection unit 4 by controlling the start and stop of the suction motor 42. Thus, the wastewater collection unit 4 has a simple structure and can efficiently absorb dirt or wastewater generated during cleaning, which is beneficial to further improving the cleaning effect and cleaning efficiency.

[0205] In the embodiments provided in this application, the cleaning equipment may also be equipped with a main unit 6, as shown in FIG1. ​​The main unit 6 may include a housing 61, and the steam generation unit 2, the auxiliary heating unit 3, the sewage collection unit 4 and the control unit 5 may be partially disposed in the housing 61 to improve the integration of the cleaning equipment, making the structure more compact and the operation more convenient.

[0206] In specific configurations, the auxiliary heating unit 3 can be fully integrated into the main unit 6, or it can be connected to the main unit 6 as an external accessory. In the embodiments provided in this application, please refer to Figure 2 for understanding. The liquid storage tank 2101, the second water pump 2102, and the electric heater 22 of the steam generation unit 2 can be integrated into the main unit 6. The auxiliary heating unit 3 can be connected to the main unit 6 as an external accessory. In one embodiment, the casing 61 of the main unit 6 can be provided with a first heat source interface 62 and a second heat source interface 63. The pipes connecting the cleaning liquid inlet and steam outlet of the auxiliary heating unit 3, in the embodiment shown in Figure 4, are the pipes connecting the liquid inlet and steam outlet of the auxiliary heater 31, and in the embodiment shown in Figure 5, are the pipes connecting the refrigerant inlet and refrigerant outlet of the heat exchanger 34, respectively. These pipes can pass through the first heat source interface 62 and the second heat source interface 63, enter the casing 61, and connect to both ends of the electric heater 22, thus achieving parallel connection of the auxiliary heating unit 3 and the electric heater 22. As shown in Figures 1 and 2, the bottom of the main unit 6 can also be provided with wheels 64, making the cleaning equipment easy to move and improving operational convenience.

[0207] In the embodiments provided in this application, as shown in Figures 1 and 2, the cleaning unit 1 further includes a handle 7; the cleaning head 1a is connected to the steam generating unit 2 and the wastewater collecting unit 4 via the handle 7. Thus, the position and orientation of the cleaning head 1a can be conveniently adjusted by holding the handle 7, which helps to improve the cleaning effect and efficiency.

[0208] In this embodiment, as shown in FIG6, the handle 7 may have a first sensing contact group 71, and the cleaning head 1a may have a second sensing contact group. The first sensing contact group 71 may be connected to the control unit 5 as shown in FIG4 and FIG5. In use, the cleaning head 1a and the handle 7 are connected, enabling the second sensing contact group and the first sensing contact group 71 to connect, so that the first sensing contact group 71 sends an electrical signal to the control unit 5. The control unit 5 can then identify the type information of the cleaning head 1a according to the electrical signal, and can adjust the working mode of the cleaning equipment according to the type information, so that the steam generating unit 2 and the sewage collection unit 4 are in the working state of the corresponding working mode.

[0209] Taking a steam cleaner as an example, steam cleaners have various working modes. For instance, there's a first type of working mode categorized by different steam temperatures, a second type categorized by whether cleaning and suction work simultaneously, and so on. There are no specific limitations. Taking the first type of working mode categorized by different steam temperatures as an example, different types of cleaning heads 1a can be used for different items to be cleaned, and different steam temperatures can be controlled for each type of cleaning head 1a.

[0210] In this embodiment, since a first sensing contact group 71 is provided on the handle 7 and cooperates with a second sensing contact group on the cleaning head 1a, the type of cleaning head 1a can be automatically identified, and the control unit 5 can be used to match different working modes for each type of cleaning head 1a, such as different cleaning temperatures, so that it can be compatible with various types of cleaning heads 1a and is suitable for multiple application scenarios.

[0211] In this embodiment, as understood with reference to Figures 4 and 5, the steam generating unit 2 may further include a temperature sensor 23. The temperature sensor 23 can be connected to the control unit 5. The temperature sensor 23 can measure the temperature of the steam sprayed by the spraying unit 21 and transmit the measured temperature information to the control unit 5. The control unit 5 can control the heating power of the electric heater 22 and / or the auxiliary heating unit 3 according to the type information of the cleaning head 1a and the steam temperature information, thereby controlling the temperature of the steam sprayed by the spraying unit 21. This enables automatic and efficient control of the steam temperature, which is beneficial for improving cleaning efficiency.

[0212] In this embodiment of the application, as shown in FIG6, the handle 7 may also be provided with a negative pressure channel 72 (the negative pressure channel 72 may be a first dirt channel or a channel connecting the first dirt channel and the sewage collection unit) and a steam pipe channel 73. A steam delivery pipe 74 (i.e., a first cleaning channel) may be provided in the steam pipe channel 73. When the cleaning head 1a and the handle 7 are connected, the nozzle 11 of the cleaning head 1a may be connected to the steam delivery pipe 74, and the suction port 12 may be connected to the negative pressure channel 72. In addition, as shown in FIG1 and FIG2, the cleaning equipment, such as a steam cleaner, may also be provided with a connecting pipe 9 (accommodating the steam delivery pipe 74 and the first dirt channel). The handle 7 may be connected to the main unit 6 through the connecting pipe 9. In one embodiment, the negative pressure channel 72 of the handle 7 may be connected to the sewage tank 41 through the connecting pipe 9, and the steam delivery pipe 74 may extend into the connecting pipe 9 and connect to the liquid outlet of the electric heater 22 after extending out of the connecting pipe 9. The connecting pipe 9 may specifically be a flexible hose, which facilitates the operation of the handle 7 to adjust the position and orientation of the cleaning head 1a. In specific settings, the type of temperature sensor 23 is not limited. For example, it can be an NTC temperature sensor, which can be installed on the steam conveying pipe 74, or on the surface of the electric heater 22 or the auxiliary heater 31. This application does not limit this.

[0213] In the embodiments provided in this application, the cleaning device further includes a self-cleaning unit 8 as shown in Figures 1 and 2; as shown in Figures 4 and 5, the self-cleaning unit 8 can be connected to the control unit 5. The self-cleaning unit 8 can be used to clean the cleaning head 1a, and the control unit 5 is used to control the start and stop of the self-cleaning unit 8. It is understood that the cleaning head 1a sprays steam to clean the surface to be cleaned, and dirt or wastewater is generated during the cleaning process. Although most of the dirt and wastewater can be collected by the wastewater collection unit 4, a small portion can still easily contaminate the cleaning head 1a, requiring frequent cleaning of the cleaning head 1a. When the cleaning head is contaminated, frequent manual cleaning is required, which is not only time-consuming and labor-intensive but also results in a poor user experience. The cleaning device provided in the above embodiments of this application, due to the self-cleaning unit 8, can automatically clean the cleaning head 1a under the control of the control unit 5, improving self-cleaning efficiency, saving manpower, and enhancing the user experience.

[0214] In specific configurations, the structure of the self-cleaning unit 8 is not limited. In one embodiment, as shown in Figures 1, 4, and 5, the self-cleaning unit 8 may include a self-cleaning box 81 and a sensor switch 82; the sensor switch 82 may be located in the self-cleaning box 81 and may be connected to the control unit 5; the cleaning head 1a may be inserted into the self-cleaning box 81 to trigger the sensor switch 82; the control unit 5 may control the start and stop of the steam generation unit 2, such as the liquid spraying unit 21, according to the state of the sensor switch 82.

[0215] Thus, during use, after the cleaning head 1a is inserted into the self-cleaning box 81, the induction switch 82 is triggered. The induction switch 82 sends a self-cleaning signal to the control unit 5, which then controls the steam generating unit 2 to start, generating steam which is then ejected through the nozzle 11 of the cleaning head 1a. Since a cleaning chamber can be formed inside the self-cleaning box 81, the steam can clean the cleaning head 1a within this chamber. In this process, only the cleaning head 1a needs to be inserted into the self-cleaning box 81, making the operation convenient and quick, achieving rapid self-cleaning of the cleaning equipment, and providing high cleaning efficiency, further enhancing the user experience. It can be seen that since the cleaning head 1a is connected to the steam generating unit 2 via the handle 7, it is clear that when the cleaning head 1a is inserted into the self-cleaning box 81 to achieve self-cleaning of the cleaning head 1a, the walls of the dirt collection pipe in the handle 7 and the main unit 6 are also cleaned, achieving self-cleaning of the cleaning head and the dirt collection pipe. It is worth noting that the induction switch 82 can be a mechanical induction switch or an infrared induction switch; there is no specific limitation.

[0216] In the embodiments provided in this application, please refer to Figures 1, 2, 4, and 5 for understanding. The control unit 5 may include a controller 51 and a control component 52 connected to each other. The control component 52 can be used to adjust the working mode of the cleaning equipment. The working mode of the cleaning equipment may include a cleaning mode and a drying mode, which can be the second type of working mode described above, divided by whether cleaning and suction work simultaneously. In the cleaning mode, the steam generating unit 2 and the wastewater collection unit 4 work simultaneously. In the drying mode, the steam generating unit 2 does not work, and the wastewater collection unit 4 works. In this way, automatic switching between cleaning and drying modes can be realized, making operation convenient and quick, and providing a better user experience. In actual settings, the specific structural form of the control component 52 is not limited. In one embodiment, the control component 52 may include a first control element 521 and a second control element 522 as shown in Figure 1. The first control element 521 can be used to control the cleaning equipment to enter or exit the cleaning mode, and the second control element 522 can be used to control the cleaning equipment to enter or exit the drying mode. In this way, dedicated control elements can be set for commonly used cleaning and drying functions, making operation more convenient and quick, and further improving the user experience.

[0217] It is worth noting that the specific form of the first control element 521 and the second control element 522 is not limited. They can be control buttons; pressing the corresponding control button will enter the corresponding working mode of the cleaning equipment, and pressing the button again will exit the corresponding working mode. Of course, they can also be control knobs; rotating the corresponding knob will allow the cleaning equipment to enter or exit the corresponding working mode. In fact, the control component 52 can also include only one control element, which can be a knob. Rotating the knob will allow the cleaning equipment to enter the cleaning mode, enter the drying mode, or be turned off.

[0218] Furthermore, the control component 52 can be located on the handle 7 or on the housing 61 of the main unit 6, and there is no specific limitation. In this embodiment of the application, as shown in FIG1, the control component 52 is located on the handle 7. When the user holds the handle 7 to control the cleaning head 1a to work, he / she can conveniently operate the control component 52 on the handle 7 to switch and start / stop the corresponding working mode.

[0219] In one embodiment, as shown in Figures 4 and 5, a first level gauge 2103 may be installed in the liquid storage tank 2101 of the steam generation unit 2, and a second level gauge 43 may be installed in the sewage tank 41 of the sewage collection unit 4. The first level gauge 2103 and the second level gauge 43 may be connected to a controller 51. The controller 51 may control the operation of the second water pump 2102 according to the liquid level of the liquid storage tank 2101 measured by the first level gauge 2103, and may control the operation of the suction motor 42 according to the liquid level of the sewage tank 41 measured by the second level gauge 43.

[0220] In this embodiment, the control unit 5 may further include a voice alarm unit 53. The voice alarm unit 53 can be connected to the controller 51. The control unit 5 can control the voice alarm unit 53 to issue a water shortage alarm when the liquid level in the storage tank 2101 is lower than the first liquid level threshold, and can control the voice alarm unit 53 to issue a full liquid level alarm when the liquid level in the wastewater tank 41 is higher than the second liquid level threshold, so as to remind the user to add water to the storage tank 2101 and drain the wastewater tank 41 in a timely manner to ensure the stable operation of the steam cleaning work. In the embodiment provided in this application, the electric heater 22 of the steam generating unit 2 may also be equipped with a temperature protection switch to prevent safety accidents caused by excessive temperature.

[0221] In the embodiment shown in Figure 4, the outlet of the electric heater 22 in the steam generation unit 2 can be connected to the nozzle 11 of the cleaning head 1a via the steam delivery pipe 74. A first control valve 24 can be installed on the pipe connecting the second water pump 2102 and the electric heater 22. In the auxiliary heating unit 3, the inlet of the auxiliary heater 31 can be connected to the outlet of the second water pump 2102 via a pipe. The outlet of the auxiliary heater 31 can be connected to the steam delivery pipe 74 via a pipe to achieve parallel connection of the auxiliary heater 31 and the electric heater 22. A second control valve 35 can be installed on the pipe connecting the auxiliary heater 31 and the second water pump 2102.

[0222] In the embodiment shown in Figure 5, unlike the embodiment shown in Figure 4, the refrigerant inlet of the heat exchanger 34 in the auxiliary heating unit 3 can be connected to the outlet of the second water pump 2102 via a pipe, and the refrigerant outlet of the heat exchanger 34 can be connected to the steam delivery pipe 74 via a pipe, so as to realize the parallel connection of the heat exchanger 34 and the electric heater 22. The aforementioned second control valve 35 can be installed on the pipe connecting the heat exchanger 34 and the second water pump 2102. Both the first control valve 24 and the second control valve 35 can be flow proportional valves. The flow rate of liquid entering the electric heater 22, such as the water flow rate, can be controlled by controlling the flow rate of the first control valve 24, or the water flow rate entering the auxiliary heating unit 3 can be controlled by controlling the opening degree of the second control valve 35, thereby controlling the steam flow rate of the steam delivery pipe 74 to control the intensity of steam cleaning. The first control valve 24 and the second control valve 35 mentioned above can both be solenoid valves. By controlling the first control valve 24 to open and the second control valve 35 to close, only the electric heater 22 can be used to heat the cleaning fluid; alternatively, both the first control valve 24 and the second control valve 35 can be opened to simultaneously heat the cleaning fluid using the electric heater 22 and the auxiliary heater 31; still, the first control valve 24 can be closed and the second control valve 35 can be opened to heat the cleaning fluid using only the auxiliary heater 31. This allows for free switching of the energy source providing heat to the steam generation unit 2. The cleaning equipment provided in the above embodiments of this application can use clean energy to provide the heat required for steam generation, reducing electricity consumption and lowering costs. It can be widely used for cleaning tableware, fabrics, glass, vehicles, clothing, kitchens, and floors, and has a wide range of applications.

[0223] After the cleaning equipment has finished cleaning the surface, the cleaning handle and the recovery pipeline of the wastewater collection unit need to be cleaned to prevent dirt adhering to the pipe walls from affecting the suction power of the cleaning equipment. In related technologies, a detachable accessory, such as a cleaning cap, is installed on the cleaning head of the cleaning handle. The cleaning fluid is sprayed onto the cleaning cap through the cleaning head and then recovered through the wastewater collection unit, achieving self-cleaning of the recovery pipeline. However, this method can cause cleaning fluid spillage, increasing the cleaning workload, and the accessory is prone to being lost.

[0224] Referring to Figures 2, 8 to 15, in one embodiment, the cleaning device includes a main unit 6, which houses a spraying unit 21 (also called a cleaning fluid supply unit) and a wastewater collection unit 4. The main unit 6 also houses a self-cleaning unit 8. The cleaning unit 1 has a first cleaning channel 710 and a first dirt channel 720 spaced apart. The first cleaning channel 710 is connected to the spraying unit 21 to spray cleaning fluid through its nozzle. The first dirt channel 720 is connected to the wastewater collection unit 4 to suck up dirt or wastewater through its suction port. In a first state, the cleaning unit 1 is detachably connected to the self-cleaning unit 8, and both the nozzle of the first cleaning channel 710 and the suction port of the first dirt channel 720 are located within the self-cleaning unit 8, enabling the cleaning device to enter a self-cleaning mode. Understandably, the first state corresponds to the cleaning device being in a non-cleaning mode, i.e., a state where the cleaning device does not need to clean the surface being cleaned. Thus, after cleaning the surface, the user can insert the cleaning unit 1 into the self-cleaning unit 8 of the main unit 6. The cleaning device can then enter the self-cleaning mode. In the self-cleaning mode, the cleaning device sprays cleaning fluid through the nozzle of the first cleaning channel 710. Under the negative pressure suction of the wastewater collection unit 4, the cleaning fluid enters the first dirt channel 720 and flows within it, thereby flushing down the dirt adhering to the walls of the first dirt channel 720 and other recovery pipes, achieving rinsing and cleaning of the recovery pipe walls. Then, the wastewater collection unit 4 collects the wastewater, realizing the self-cleaning of the cleaning device's recovery pipes. In some embodiments, the self-cleaning unit 8 can be a first slot 611 located in the main unit 6. In other embodiments, the self-cleaning unit can also be the self-cleaning box 81 of the aforementioned embodiments.

[0225] The following description uses the self-cleaning unit 8 as an example, located in the first slot 611 of the main unit 6, and the cleaning unit 1 including the handle 7. Referring to Figures 2, 8 to 15, in one embodiment, the handle 7 is provided with the aforementioned first cleaning channel 710 and first dirt channel 720. In the first state, the handle 7 is detachably connected to the first slot 611, and the outlet of the first cleaning channel 710 and the inlet of the first dirt channel 720 are both located within the first slot 611, enabling the cleaning device to enter self-cleaning mode. Thus, after cleaning the surface, the user can insert the handle 7 into the first slot 611 of the main unit 6, allowing the cleaning device to enter self-cleaning mode. By providing the first slot 611 in the main unit 6, the handle 7 can be directly inserted into the first slot 611 after use, allowing the cleaning device to enter self-cleaning mode without requiring the user to attach additional cleaning accessories such as a cleaning cap, reducing user operation steps. Furthermore, while achieving self-cleaning of the cleaning device's recovery pipeline, it also allows for the storage of the handle 7. Meanwhile, since no additional cleaning accessories are required, the risk of losing cleaning accessories is reduced, and the cost of using cleaning accessories is also reduced. Furthermore, when the handle 7 is inserted into the first slot 611, a closed space is formed between the first slot 611 and the handle 7, which effectively reduces the possibility of overflow of cleaning fluid and recycled dirt, thus reducing the user's cleaning workload and improving the utilization rate of cleaning fluid.

[0226] Referring to Figures 8 and 9, in one embodiment, a first gap 615 is formed between the outer peripheral surface of the handle 7 and the side wall of the first slot 611 along the radial direction of the handle 7. Thus, when entering the self-cleaning mode, the cleaning device can introduce outside air through this first gap to maintain an internal negative pressure environment, allowing the cleaning fluid to enter the first waste channel 720 under the negative pressure suction of the wastewater collection unit, thereby flushing and cleaning the wall of the recovery pipeline. In one embodiment, the first gap 615 is greater than or equal to 0.2 mm. By reserving a certain gap, sufficient airflow is ensured, guaranteeing suction efficiency while ensuring the suction process can continue. Furthermore, the introduction of outside air helps to dilute and disperse the waste, making it easier for the waste to be transferred to the wastewater collection unit.

[0227] Referring to Figures 8 to 11, in one embodiment, one of the handle 7 and the first slot 611 is provided with a first marking part 730, and the other is provided with a first acquisition part 6111. In response to the connection between the handle 7 and the first slot 611, the first acquisition part 6111 can identify the first marking part 730, and the cleaning device enters a self-cleaning mode or a standby self-cleaning mode. When the handle 7 is inserted into the first slot 611, the first acquisition part 6111 identifies the first marking part 730 and transmits the signal of handle 7 insertion to the control unit of the cleaning device. This allows the cleaning device to accurately determine whether the handle 7 has been correctly inserted back into the first slot 611, and then directly enter the self-cleaning mode or the standby self-cleaning mode. After entering the standby self-cleaning mode, the user can click to confirm and start self-cleaning. This adds a layer of safety and user control mechanism, allowing the user to confirm that the device and surrounding environment are ready before starting self-cleaning, avoiding accidental cleaning operations caused by accidental touch or failure to notice the device status. When the cleaning equipment enters self-cleaning mode, cleaning fluid is sprayed out through the first cleaning channel 710. The cleaning fluid flows within the first dirt channel 720, thereby flushing off the dirt adhering to the walls of the first dirt channel 720 and other recovery pipes, achieving rinsing and cleaning of the recovery pipe walls. The dirt is then recovered by the wastewater collection unit. The entire process forms a continuous cleaning cycle until the recovery pipes achieve the desired cleaning effect. The closed cleaning cycle system reduces the outflow of cleaning fluid, improves fluid utilization efficiency, and reduces the user's cleaning workload. Referring to Figures 8 to 11, in one embodiment, the first marking part 730 is disposed on the handle 7, and the first collection part 6111 is disposed on the main unit 6. In addition to cooperating with the first acquisition unit 6111 to enable the cleaning device to enter self-cleaning mode, in some embodiments, the first marking unit 730 stores type information of the handle 7. When the handle 7 is inserted into the first slot 611 of the main unit 6, the first acquisition unit 6111 can identify the first marking unit 730 and transmit a signal to the control unit of the cleaning device. The control unit can identify the type information of the handle 7 based on the signal, and then adjust the operating parameters of the cleaning device according to the type information, such as adjusting the suction force or suction power. In other embodiments, the first acquisition unit can be located on the handle, and the first marking unit can be located on the main unit.

[0228] Referring to Figure 8, in one embodiment, one of the first marking part 730 and the first acquisition part 6111 is configured as a male connector, and the other is configured as a female connector for connection with the male connector. For example, the first marking part 730 is a male connector and the first acquisition part 6111 is a female connector; of course, the first marking part 730 can also be a female connector and the first acquisition part 6111 can be a male connector. In some embodiments, the male connector can be a PIN pin, and the female connector can be a PIN pin connection hole. When the handle 7 is inserted into the first slot 611, the PIN pin on the handle 7 connects to the PIN pin connection hole on the host 6, and the information on the first marking part 730 is read through the physical contact between the two to realize signal transmission. In other embodiments, the first marking part 730 can be a short-range communication module such as QR code, NFC, RFID or Bluetooth, and the first acquisition part 6111 can be a reader or receiver. For example, when the first tag unit 730 is a QR code, the first acquisition unit 6111 can use a camera or barcode scanner as a reader to read information and transmit signals; when the first tag unit 730 is NFC, the first acquisition unit 6111 can use a card reader as a reader; when the first tag unit 730 is RFID, the first acquisition unit 6111 can use an RFID reader as a reader; when the first tag unit 730 is Bluetooth, the first acquisition unit 6111 can use a Bluetooth receiver as a reader to read information and transmit signals.

[0229] In one embodiment, at least one of the main unit 6 and the handle 7 is provided with an operating element (not shown). In a first state, in response to the selection operation of the operating element, the cleaning device is in self-cleaning mode. In some embodiments, the operating element may be located on the main unit 6, for example, the operating element may be a self-cleaning button located on the main unit 6. When the handle 7 is inserted into the first slot 611, the user presses the self-cleaning button on the main unit 6 to enable the cleaning device to enter self-cleaning mode. Of course, in other embodiments, the operating element may also be a self-cleaning button integrated on the handle 7. In another embodiment, the operating element may also be a touch screen control, where the user interacts with the device by touching the screen. For example, the main unit 6 or the handle 7 may have a touch screen interface, and the operating element may be a graphical virtual button, slider, or switch displayed on the touch screen interface. When the handle 7 is inserted into the first slot 611, the user clicks the operating element to enable the device to enter self-cleaning mode. It is understood that in some embodiments, an operating element may not be provided, and the cleaning device automatically enters self-cleaning mode when the handle 7 is inserted into the first slot 611 of the main unit 6.

[0230] Referring to Figures 7 to 9, in one embodiment, the main unit 6 is provided with a mounting base 610, which has a first slot 611. By connecting the handle 7 to the main unit 6 using the mounting base 610, the mounting base 610 provides additional support without occupying internal space of the main unit 6. In one embodiment, the mounting base 610 can be located on the side of the main unit 6 in the horizontal direction. This arrangement makes the insertion position of the handle 7 more ergonomic, allowing the user's wrist and arm to maintain a natural and comfortable angle during use, reducing fatigue from prolonged operation. Moreover, being located on the side provides more space for the user to easily insert and remove the handle 7. In some embodiments, the mounting base 610 and the main unit 6 can be integrally formed. Of course, in other embodiments, the mounting base 610 can also be detachably connected to the main unit 6 as an independent module via threaded connection, snap-fit ​​connection, or magnetic connection, thus facilitating the maintenance and replacement of the mounting base 610. Referring to Figures 7 to 9, in one embodiment, the mounting base 610 is constructed with a stop plate 612 extending along the direction of gravity. A second gap exists between the stop plate 612 and the horizontal side of the main unit 6, forming a storage groove 613. Thus, when the handle 7 is inserted into the first slot 611, connecting pipes, such as those connecting the main unit 6 and the handle 7, as well as control wiring harnesses, such as power lines and control lines, can be neatly wound around the mounting base 610, i.e., accommodated within the storage groove 613. This improves aesthetics and reduces the risk of tangling. Simultaneously, storing the pipes and control wiring harnesses within the storage groove 613 saves space. The stop plate 612 can block and limit the pipes and control wiring harnesses, preventing them from detaching from the storage groove 613 horizontally. In some embodiments, the stop plate 612 can be symmetrical in shape, facilitating its manufacturing.

[0231] Referring to Figures 7 to 9, in some embodiments, the mounting base 610 is provided with heat dissipation holes 614. These holes allow heat to dissipate through airflow, increasing air circulation around the mounting base 610, helping to remove heat, improving its heat dissipation performance, preventing overheating, and thus preventing the insulation layer or conduit of the control harness wound on the mounting base 610 from aging or melting due to high temperatures, thereby extending the service life of the control harness, conduit, and the entire cleaning equipment. In one embodiment, the cleaning equipment also includes a receiving tube for accommodating at least one of the first cleaning channel 710, the first dirt channel 720, and the control harness of the cleaning equipment. The receiving tube can be housed in a receiving groove 613. By housing the conduit and control harness in the receiving tube, the receiving tube provides protection, reducing the chance of the conduit and control harness coming into contact with the ground or other sharp objects, thereby reducing the risk of wear and extending their service life. In some embodiments, the receiving tube can be a corrugated pipe, which has good flexibility and bendability, making it easy to coil within the receiving groove 613.

[0232] Referring to Figures 12 and 13, in one embodiment, the cleaning device includes at least one cleaning head 1a detachably connected to the handle 7. That is, different types of cleaning heads 1a can be connected to the handle 7, such as the cleaning head 1a in the embodiment shown in Figure 12, or the cleaning head 1a in the embodiment shown in Figure 14. Of course, other types of cleaning heads 1a can also be used, which will not be listed here. By connecting different types of cleaning heads 1a to the handle, corresponding usage scenarios can be matched. In some embodiments, the handle 7 is provided with a first collection unit 6111, and the cleaning head 1a is provided with a second marking unit (not shown). When the cleaning head 1a is connected to the handle 7, the first collection unit 6111 can recognize the second marking unit, and the cleaning device enters a cleaning mode matching the cleaning head 1a. The second marking section stores the type information of the cleaning head 1a. The first acquisition section 6111 identifies the second marking section and transmits the signal to the control unit of the cleaning equipment. The control unit can identify the type information of the cleaning head 1a based on the signal and then adjust the cleaning mode of the cleaning equipment according to the type information, such as adjusting the suction force, suction power or the temperature of the sprayed cleaning liquid, to match the actual use scenario.

[0233] It should be noted that when the first marking part 730 in the aforementioned embodiment is disposed on the host 6, and the first collection part 6111 for identifying the first marking part 730 is disposed on the handle 7, the first collection part 6111 for identifying the second marking part and the aforementioned first collection part 6111 for identifying the first marking part 730 can refer to the same component. That is, when the cleaning head 1a is connected to the handle 7, the first collection part 6111 can identify the second marking part, and when the handle 7 is connected to the first slot 611 of the host 6, the first collection part 6111 can identify the first marking part 730. Of course, in other embodiments, the first collection part for identifying the second marking part and the aforementioned first collection part 6111 for identifying the first marking part 730 can also refer to different components. That is, at least two first collection parts 6111 are provided, at least one first collection part 6111 is used to identify the first marking part 730, and at least one first collection part is used to identify the second marking part.

[0234] The cleaning head 1a and the handle 7 can be connected by threads, snap-fit, pins, or magnets. For example, in the embodiment shown in Figure 12, the cleaning head 1a and the handle 7 can be connected by snap-fit. For instance, the cleaning head 1a is provided with a protruding elastic snap, and the handle 7 is provided with a slot. When the cleaning head 1a is sleeved on the handle 7, the elastic snap is engaged in the slot, thus fixing the cleaning head 1a and the handle 7. The cleaning head 1a is provided with a spaced nozzle 11 and a negative pressure port 230 (i.e., the suction port in the aforementioned embodiment); the nozzle 11 is connected to the outlet of the first cleaning channel 710, and the negative pressure port 230 is connected to the inlet of the first waste channel 720. Thus, the cleaning fluid supply unit sprays cleaning fluid onto the surface to be cleaned through the nozzle 11 of the cleaning head 1a, thereby cleaning the stains on the surface to be cleaned. The negative pressure suction generated on the surface to be cleaned is achieved through the negative pressure port 230. The dirt and wastewater generated during cleaning can be sucked into the wastewater collection unit through the negative pressure port 230 under the action of the negative pressure suction, so as to absorb the cleaned dirt.

[0235] Referring to Figures 12 and 13, in some embodiments, taking a cylindrical cleaning head 1a as an example, the nozzle 11 is located on the central axis of the cleaning head 1a, and multiple negative pressure ports 230 are provided, which are arranged at intervals along the circumference of the nozzle 11. By arranging multiple negative pressure ports 230 around the outer circumference of the nozzle 11, the distribution of negative pressure suction on the surface being cleaned can be relatively uniform, thereby ensuring that the cleaning liquid sprayed from the nozzle 11 receives relatively uniform negative pressure suction, which can improve the cleaning effect and make the cleaning process easier and more convenient. At the same time, it can also prevent stains on the surface being cleaned from being sprayed away by the cleaning liquid, making the cleaning more effective, and it can also make the overall structure of the cleaning head 1a more compact and adaptable to various surfaces being cleaned. In some embodiments, the negative pressure ports 230 can be set as arc-shaped, such as circular, elliptical, or waist-shaped. In other embodiments, the negative pressure port may be located on the central axis of the cleaning head, with multiple nozzles arranged circumferentially around the outer side of the negative pressure port. This ensures a relatively uniform distribution of the cleaning fluid on the surface being cleaned, improving the cleaning effect. As shown in Figures 14 to 16, in some embodiments, the nozzles 11 may be arranged in a straight line, resulting in a larger flow rate and coverage area of ​​the cleaning fluid, better meeting cleaning needs. Of course, the arrangement of the nozzles 11 is not limited to this; it can be configured according to actual usage requirements.

[0236] Referring to Figures 12 and 13, in one embodiment, the cleaning head 1a is provided with a scraping portion 13 protruding relative to the nozzle 11. The scraping portion 13 is spaced apart from the nozzle 11, and at least a portion of the scraping portion 13 is covered by the cleaning liquid sprayed from the nozzle 11. By providing the scraping portion 13 to protrude relative to the nozzle 11 and the negative pressure port 230, on the one hand, the scraping portion 13 can scrape and contact the surface to be cleaned, achieving a physical cleaning effect. By moving or rotating the scraping portion 13 back and forth, stubborn stains on the surface to be cleaned can be removed more easily, thereby improving the cleaning effect on the surface to be cleaned. On the other hand, after the cleaning liquid is sprayed onto the surface to be cleaned, it is bounced up, flows through the scraping portion 13, and then enters the negative pressure port 230, thereby removing the stains from the scraping portion 13, thus achieving self-cleaning of the scraping portion 13 and reducing the possibility that the stains on the scraping portion 13 will affect the subsequent cleaning effect.

[0237] In one embodiment, the scraping part 13 includes at least one of a scraper, a scraper blade, a roller brush, a bristle brush, a protrusion, a scouring pad, and a cleaning ball. It can be adapted to various application scenarios, such as cleaning tableware, kitchen appliances, fabrics, windows, shoes, and floors. When the scraping part 13 is a scraper blade, scraper blade, bristle brush, or roller brush, it can move back and forth or roll, making repeated physical contact with dirt during the cleaning process, thereby loosening the dirt. When the scraping part 13, such as the scraper blade, scraper blade, bristle brush, or roller brush, has been used for a long time, the scraping part 13 can be removed from the cleaning head 1a, and only the scraper blade, scraper blade, bristle brush, roller brush, and other consumables can be replaced. Of course, the cleaning head 1a connected to the scraper blade, scraper blade, bristle brush, roller brush, etc., can also be replaced entirely from the cleaning equipment. When the scraping part 13 is a scouring pad or a cleaning ball, if the scraping part 13 is used for a long time, only the scouring pad or the cleaning ball needs to be replaced, thereby improving the convenience of replacement, increasing cleaning efficiency, and saving replacement costs.

[0238] Referring to Figures 12 and 13, in one embodiment, the scraping part 13 can be a raised contact point, and multiple raised contact points can be provided, arranged circumferentially along the nozzle 11. Providing multiple contact points can further enhance the physical cleaning effect of the cleaning head 1a, making it more effective for cleaning stubborn stains on the surface being cleaned. In some embodiments, the raised contact points can be made of a flexible material, such as silicone, rubber, or nylon contact points, which have a certain degree of deformability and can adapt to curved or rough surfaces, for example, for cleaning fabric items.

[0239] Referring to Figures 14 to 16, in some embodiments, the scraping part 13 can be a straight scraper, which can be used to clean hard surfaces such as glass and countertops. The cleaning liquid sprayed from the nozzle 11 forms an angle of 5 to 30 degrees with the scraper. The cleaning liquid is sprayed onto the boundary between the surface being cleaned and the scraper. The liquid scraped off by the scraper can be collected by the negative pressure port 230, and it also removes dirt from the scraper, thus achieving self-cleaning of the scraper. There can be one or more scrapers. For example, in the embodiment shown in the figures, there are two scrapers, increasing the scraping area and providing mutual support. In some embodiments, the negative pressure port 230 can be located on one of the scrapers, and the two scrapers can be set at a preset angle, maintaining a certain gap between them to ensure smooth airflow. One scraper can be a hard scraper, and the other can be a flexible scraper made of high-temperature resistant rubber. Of course, in other embodiments, only one scraper can be provided, depending on the actual usage requirements.

[0240] In one embodiment, the cleaning fluid includes at least one of water vapor, water, and a solution containing detergent, which can be selected by those skilled in the art according to actual needs. When water vapor is used as the cleaning fluid, the cleaning equipment also includes a steam generator (not shown), which generates high-temperature, high-pressure water vapor from clean water and sprays it onto the surface to be cleaned through a nozzle. In one embodiment, the steam generator can be a heater. By using water vapor as the cleaning fluid, the high temperature of the water vapor, while being directly sprayed, can also accelerate the dissolution of stains, further improving the cleaning effect. When water or a solution containing detergent is used as the cleaning fluid, the spray pressure can be increased, improving the spray force, which is more effective for cleaning larger volumes of dirt.

[0241] In a practical application scenario, cleaning equipment can be a steam cleaner, carpet cleaner, floor scrubber, cleaning robot, vacuum cleaner, high-pressure washer, or medical disinfection and cleaning equipment. The cleaning fluid supply unit in the cleaning equipment supplies cleaning fluid to the surface being cleaned through the cleaning head, thus removing stains. After cleaning, the wastewater is collected through a negative pressure port by the negative pressure suction generated by the wastewater collection unit.

[0242] In related technologies, the cleaning head of cleaning equipment cannot self-clean after the brush comes into contact with dirt, requiring manual cleaning before the next cleaning cycle can begin, which greatly reduces cleaning efficiency and results in a poor user experience.

[0243] Please refer to Figure 17. In one embodiment of this application, the cleaning unit 1 of the cleaning device includes a cleaning head 1a. The cleaning head 1a includes a housing 10 and a cleaning component 20 (i.e., the scraping part in the aforementioned embodiment). The cleaning component 20 is used to clean the object to be cleaned. The housing 10 is provided with a nozzle 11 and a negative pressure port 230 (i.e., the suction port in the aforementioned embodiment). In some embodiments, at least a portion of the cleaning component 20 is housed within the negative pressure port 230. With this configuration, when the cleaning head 1a is cleaning dirt, some of the dirt adhering to the cleaning head 1a can be sucked in by the negative pressure port 230, thus achieving partial self-cleaning of the cleaning component 20. The cleaning fluid in this embodiment includes high-pressure water vapor.

[0244] In the first embodiment, at least a portion of the cleaning component 20 is housed within the negative pressure port 230. This arrangement allows some of the dirt adhering to the cleaning head 1a to be drawn into the negative pressure port 230 during cleaning, thus achieving partial self-cleaning of the cleaning component 20. The cleaning fluid in this embodiment includes high-pressure steam. Experimental verification shows that this design allows 60%-70% of the dirt on the cleaning component 20 to be drawn into the negative pressure port 230, meaning the cleaning head achieves self-cleaning to a certain extent and also extends the cleaning time of a single cycle.

[0245] In the second embodiment, the cleaning fluid sprayed from the nozzle 11 is tilted to rinse the cleaning part of the cleaning component, meaning that at least a portion of the cleaning component 20 is designed to be covered by the cleaning fluid sprayed from the nozzle 11. This configuration allows the cleaning fluid sprayed from the nozzle 11 to wash away some of the dirt adhering to the cleaning component 20, thus achieving partial self-cleaning of the cleaning component 20. The cleaning fluid in this embodiment includes high-pressure steam, pressurized water, or a pressurized cleaning solution. Experimental verification shows that the above design can wash away 70%-80% of the dirt on the cleaning component 20, meaning the cleaning head achieves self-cleaning to a certain extent and also extends the cleaning time of a single cleaning cycle to some extent.

[0246] As a third embodiment of this application, please refer to Figure 17 for understanding. While at least a portion of the cleaning component 20 is housed within the negative pressure port 230, at least a portion of the cleaning component 20 can also be covered by the cleaning liquid sprayed from the nozzle 11. It can be understood that this third embodiment integrates the first and second embodiments. That is, when the cleaning head is cleaning dirt, some dirt on the cleaning component 20 is washed away by the cleaning liquid sprayed from the nozzle 11, and some dirt is sucked into the negative pressure port 230. Furthermore, dirt washed off the cleaning component 20 is also sucked into the negative pressure port 230. It can be seen that the self-cleaning effect of the cleaning head disclosed in this embodiment is far greater than the self-cleaning effect of the two embodiments mentioned above. Through experimental verification, the above design can clean 98%-100% of the dirt on the cleaning component 20, that is, it basically achieves complete self-cleaning of the cleaning head, greatly extending the cleaning time of a single cleaning cycle, thereby improving the user experience. It should be noted that the cleaning component 20 being housed in at least a portion of the negative pressure port 230 includes at least two implementations: one implementation is that the cleaning component 20 is a single scraper, wherein the single scraper is embedded in the negative pressure port 230; the other implementation is that the cleaning component 20 is a double scraper, wherein one of the double scrapers is embedded in the negative pressure port 230, or both scrapers are embedded in the negative pressure port 230.

[0247] This application does not limit the specific structure of the cleaning component 20; any structure that meets the usage requirements of this application is within the protection scope of this application. As one embodiment, the cleaning component 20 disclosed in this application includes a positioning part and a cleaning part 202. The positioning part 201 is at least used to fix the cleaning part 202 to the housing 10, and the cleaning part 202 is at least used to clean the object to be cleaned.

For example, in actual installations, there is no need to additionally provide a positioning part for positioning the cleaning part 202; simply using the side plate forming the negative pressure port 230 as the mounting end for the positioning part 201 to clamp the cleaning part 202 is sufficient. In this case, the cleaning part 202 can be placed within the negative pressure port 230. This design reduces the number of components in the entire cleaning head, effectively lowering costs.

[0258] As a further embodiment, in the cleaning head disclosed in this application, the height of the mounting ridge 2031 can be set greater than the height of the groove edge of the fixing groove 1032a. This allows the first cleaning part 203 and the second cleaning part 204 to maintain a certain gap under negative pressure due to the support of the upper surface of the ridge, thereby ensuring the gas flow of the negative pressure port 230. Of course, in the cleaning head disclosed in this application, the height of the fixing ridge can also be set greater than the height of the groove edge of the mounting groove. In this case, the first cleaning part is engaged in the negative pressure port, thus also allowing the first cleaning part 203 and the second cleaning part 204 to maintain a certain gap under negative pressure, thereby ensuring the gas flow of the negative pressure port 230.

[0259] As a further embodiment, the mounting ridge 2031 disclosed in this application is provided with a T-shaped protrusion. The two sides of the T-shaped protrusion are engaged with the upper surface of the groove edge of the fixing groove 1032a, as shown in FIG21. The upper surface of the T-shaped protrusion abuts against the inner surface of the second cleaning part 204 under high negative pressure, thereby maintaining a certain gap between the inner surface of the first cleaning part 203 and the inner surface of the second cleaning part 204 to ensure gas flow through the negative pressure port 230.

[0260] Similarly, the fixing protrusion disclosed in this application embodiment is provided with a T-shaped protrusion, the two sides of which are engaged with the upper surface of the groove edge of the mounting groove.

In other words, support ribs, support points, or support protrusions may be provided only on the inner surface of the first cleaning part 203, and support ribs, support points, or support protrusions may be provided only on the inner surface of the second cleaning part 204. Alternatively, support ribs, support points, or support protrusions may be provided on the inner surfaces of both the first cleaning part 203 and the second cleaning part 204. It should be explained that the aforementioned inner surfaces refer to the two surfaces of the first cleaning part 203 and the second cleaning part 204 that are close to each other under negative pressure.

[0261] As a specific embodiment of this application, the first cleaning part 203 is disposed on the inner or outer side of the side plate of the negative pressure port 230 by means of a mounting protrusion 2031 or a mounting groove, and the second cleaning part 204 is disposed on the inner or outer side of the side plate of the negative pressure port 230 by means of a mounting protrusion or a mounting groove.

[0262] As a further embodiment of this application, the cleaning end of the cleaning component 20 disclosed in this application extends at least 0.5mm-20mm beyond the negative pressure port. This arrangement allows the cleaning end of the cleaning part 202 to maintain a certain distance from the negative pressure port 230, thereby balancing the jetting force of the nozzle 11 and the suction force of the negative pressure port 230, ensuring that the jetting force of the nozzle 11 is not affected by the negative pressure port 230. It should be explained that "exceeds" means that the cleaning end of the cleaning component 20 extends towards the surface of the object being cleaned, extending beyond the cross-section of the negative pressure port 230. In the embodiments provided in this application, the cleaning part 202 includes at least one of a scraper, a scraper blade, a roller brush, a bristle brush, a scouring pad, and a cleaning ball.

The installation end is a roller that passes through the cleaning end, and the two ends of the roller are connected to the two positioning holes one by one. The cleaning end extends out of the negative pressure port 230 for cleaning the object to be cleaned.

[0267] As a fifth specific embodiment of this application, the positioning part 201 consists of a first positioning side plate 2011 and a second positioning side plate 2012 that are disposed opposite to each other forming a negative pressure port 230. The cleaning part 202 is a brush, wherein the brush includes an installation end and a cleaning end. The cleaning end is bonded to the installation end.

[0268] As a sixth specific embodiment of this application, the positioning part 201 consists of a first positioning side plate 2011 and a second positioning side plate 2012 arranged opposite to the negative pressure port 230. The cleaning part 202 includes a clamping plate and a cleaning ball. The clamping plate is engaged within the negative pressure port 230, a portion of the cleaning ball is clamped by the clamping plate, and a portion of the cleaning ball serves as a cleaning end for cleaning the object to be cleaned. When the cleaning part 202 is a scraper or scraper, it can clean glass, etc.; when the cleaning part 202 is a roller brush or brush, it can clean fabrics, etc.; when the cleaning part 202 is a scouring pad or cleaning ball, it can clean the surfaces of pots, bowls, stoves, etc. The embodiments of this application do not limit the specific number of cleaning components 20. The cleaning component 20 can be one, two, three, or more. Any structure that meets the usage requirements of this application is within the protection scope of this application. In the embodiments provided in this application, the cleaning component 20 is preferably two or more, and each cleaning component 20 is arranged in parallel. It is worth noting that the cleaning end of the cleaning component 20 can be a brush, a protrusion, etc., as long as it is parallel to the length direction of the negative pressure port 230.

[0269] In the embodiments provided in this application, the nozzle 11 and the negative pressure port 230 are arranged adjacent to each other. The nozzle 11 is provided with at least one cleaning fluid injection hole 1021, and the spray direction of the cleaning fluid injection hole 1021 is inclined towards the cleaning component 20. With this arrangement, the cleaning fluid injection hole 1021 can directly spray at least a portion of the cleaning fluid into the cleaning component 20 to achieve the purpose of self-cleaning.

[0270] As a further embodiment, the nozzle 11 disclosed in this application includes at least one cleaning fluid injection pipe 102, wherein the cleaning fluid injection pipe 102 is provided with a plurality of cleaning fluid injection holes 1021. The cleaning fluid injection pipe 102 is arranged along the length direction of the nozzle 11, and the cleaning fluid injection holes 1021 are preferably evenly distributed along the length direction of the cleaning fluid injection pipe 102. In this embodiment, the cleaning fluid is preferably high-pressure steam. The steam ejected from at least one of the plurality of injection holes 1021 is inclined towards the cleaning end so that the steam is sprayed onto the cleaning end. The steam ejected from the plurality of injection holes can be sprayed parallel to the cleaning end, or it can form a certain spray angle, with part spraying towards the cleaning end and part spraying towards the surface to be cleaned. This application does not limit the specific type of cleaning fluid, wherein the cleaning fluid includes at least one of water vapor, water, and a solution containing a cleaning agent, which can be selected by those skilled in the art according to actual needs.

[0271] It is worth noting that when using steam as the cleaning fluid, the high temperature of the steam during direct spraying can accelerate the dissolution of stains and further improve the cleaning effect. When using water or a solution containing detergent as the cleaning fluid, increasing the spray pressure and spraying force is more effective for cleaning larger volumes of dirt.

[0272] In one embodiment, the cleaning head is detachably connected to the main unit, or at least a portion of the cleaning assembly 20 is detachably connected to the main unit.

[0273] In one embodiment, a liquid sensor for detecting liquid is installed on the connecting pipe between the storage tank and the second water pump, and a level sensor for detecting the liquid level in the wastewater tank is installed inside the wastewater tank. The liquid sensor and the level sensor are electrically connected to the controller, which can control the operation of the spraying unit or the suction unit based on the liquid or liquid level detected by the level sensor. Furthermore, a steam generator is installed between the second water pump and the nozzle. The steam generator converts the clean water pumped in by the second water pump into high-temperature, high-pressure steam as a cleaning fluid, which is sprayed through the cleaning fluid spray nozzle onto the surface of the object being cleaned and the cleaning end surface of the cleaning components, thereby achieving self-cleaning of the cleaning components.

[0274] Cleaning equipment typically includes a handheld cleaning head, which can be used to remove dust and clean surfaces. A handheld cleaning head generally consists of a nozzle body and a dust cover detachably attached to the nozzle body, forming a dust collection channel between them. To ensure the dust collection channel remains clear, the dust cover needs to be periodically removed from the nozzle body for cleaning. In related technologies, when the dust cover is removed, the nozzle body also separates from the handle. Therefore, when reinstalling the dust cover, it is necessary to reconnect the nozzle body and handle, increasing the complexity of subsequent operations and affecting the efficiency of installation and removal. Based on this, a cleaning device provided in an embodiment of this application solves the above-mentioned technical problems. The cleaning unit in the cleaning device includes a cleaning head, which will be described in detail below.

[0275] Referring to Figures 22A to 24 and Figures 27 to 31, a cleaning unit 1 provided in one embodiment of this application includes a cleaning head 1a. The cleaning head 1a includes a nozzle body 100, a dust cover 200, and a handle 7. The nozzle body 100 is provided with a first mating part 120 and a first dial part 110; the dust cover 200 is provided with a second mating part 210; and the handle 7 is provided with a first snap-fit ​​part 310. When the first dial part 110 is in the locked position, the first dial part 110 is connected to the second mating part 210. The first latching portion 310 can be sequentially connected to the first mating portion 120 and the second mating portion 210 to connect the nozzle body 100 and the dust cover 200 to the handle 7; the first dial portion 110 is configured to be operablely toggled to move from the locked position to the first unlocked position; the first dial portion 110 in the first unlocked position can press against the first latching portion 310 to disengage the first latching portion 310 from the second mating portion 210, while the first latching portion 310 remains connected to the first mating portion 120.

[0276] By setting the first dial part 110 on the nozzle body 100, when it is necessary to remove the dust cover 200, the first dial part 110 is turned in the direction of the arrow shown in Figure 22B, so that the first dial part 110 presses against the first locking part 310. At this time, the dust cover 200 can be pushed in the direction of the arrow shown in Figure 22B. The dust cover 200 will act on the first dial part 110, thereby driving the first dial part 110 and the first locking part 310 to move down in the direction perpendicular to the arrow, so that the first locking part 310 is disconnected from the second mating part 210 on the dust cover 200, while the first locking part 310 and the first mating part 120 remain connected, that is, the handle 7 and the nozzle body 100 are still connected. Thus, after removing the dust cover 200, there is no need to reconnect the handle 7 and the nozzle body 100. The dust cover 200 can be directly assembled after cleaning, avoiding the hassle of reconnecting the handle 7 after removing the dust cover 200 from the nozzle body 100. This simplifies the operation process, reduces the complexity of subsequent operations, and improves disassembly and assembly efficiency. Simultaneously, since frequent reconnection of the handle 7 and the nozzle body 100 is not required after removing the dust cover 200, the risk of wear between the handle 7 and the nozzle body 100 is significantly reduced, helping to extend the service life of the handle 7 and the nozzle body 100, thereby ensuring the stability and reliability of the cleaning head. In other embodiments, the first toggle part 110 can be turned clockwise in the direction of the arrow shown in Figure 22B, thereby pressing against the first locking part 310 and causing the first locking part 310 to move downwards, disengaging the first locking part 310 from the second mating part 210.

[0277] As shown in Figures 22B and 31, it can be understood that when the first dial portion 110 is in the locked position, the first dial portion 110 protrudes from the outer surface of the dust cover 200 and the handle 7, making it convenient for the user to move the first dial portion 110. In some embodiments, the first locking portion 310 is provided with a protruding locking block, and the first mating portion 120 and the second mating portion 210 can be locking grooves for engaging with the locking block. In some embodiments, the first locking portion 310 may also be provided with a receiving groove, and when the nozzle body 100 is connected to the handle 7, a portion of the first dial portion 110 is located in the receiving groove.

[0278] Referring to Figures 22B and 29 to 33, in one embodiment, the sidewall of the second mating part 210 is constructed with a guide slope 211, and the first knob part 110 is constructed with a mating slope 111 for sliding engagement with the guide slope 211. Thus, when the dust cover 200 is pushed in the direction of the arrow shown in Figure 22B, the sliding engagement between the guide slope 211 on the dust cover 200 and the mating slope 111 of the first knob part 110 converts the movement of the dust cover 200 in the direction of the arrow into a downward movement of the first knob part 110 in a direction perpendicular to the arrow. This causes the first knob part 110 to move the first locking part 310 downward, causing the first locking part 310 to disengage from the first mating part 120. Meanwhile, when installing the dust cover 200, the installation direction of the dust cover 200 is opposite to the direction of the arrow shown in Figure 22B. The movement of the dust cover 200 can be guided by the sliding engagement of the guide slope 211 and the mating slope 111, so that the first knob part 110 passes through the second mating part 210 and the first snap-fit ​​part 310 passes through the second mating part 210, thereby realizing the connection of the dust cover 200, the nozzle body 100 and the handle 7.

[0279] Referring to Figure 29, in some embodiments, the first dial portion 110 is provided with a first limiting protrusion 112. When the first dial portion 110 is in the locked position, the first limiting protrusion 112 prevents the first dial portion 110 from disengaging from the second mating portion 210. Thus, before removing the dust cover 200, the first dial portion 110 needs to be turned along the direction of the arrow shown in Figure 29 to place it in the unlocked position. That is, the first limiting protrusion 112 is no longer directly above the surface of the dust cover 200, and the first limiting protrusion 112 will not interfere with the movement of the dust cover 200, thereby facilitating the removal of the dust cover 200. In other words, by providing the first limiting protrusion 112, the connection reliability of the first dial portion 110 and the second mating portion 210 can be improved, that is, the connection reliability of the nozzle body 100 and the dust cover 200 can be improved, reducing the possibility of the dust cover 200 disintegrating due to misoperation.

[0280] Referring to Figure 27, in one embodiment, the outer surface of the dust cover 200 is provided with a protruding removal portion 220; when the first toggle part 110 is in the first unlocked position, the removal portion 220 is configured to be operably pushed to disengage the dust cover 200 from the nozzle body 100. As shown in Figure 27, the pushing direction of the removal portion 220 is indicated by arrows. By providing a protruding removal portion 220 on the dust cover 200, a force application position is provided for the user, making it convenient for the user's fingers to apply force to the removal portion 220 to push the dust cover 200 to move, so that the first locking part 310 and the second mating part 210 are separated, which facilitates the disassembly operation of the dust cover 200 and reduces hand fatigue.

[0281] Referring to Figure 27, in one embodiment, the removal part 220 protrudes from the first switch part 110. This design serves two purposes: firstly, the removal part 220 can partially shield the first switch part 110, preventing the dust cover 200 from accidentally detaching due to user accidental touch of the first switch part 110; secondly, it allows users to quickly and accurately distinguish between the removal part 220 and the first switch part 110, improving disassembly efficiency.

[0282] Referring to Figure 31, in some embodiments, the pushing surface 221 of the removal part 220 is inclined relative to the outer surface of the dust cover 200. That is, the pushing surface 221 is an inclined surface. On the one hand, the inclined surface design can intuitively guide the user to apply force in the correct direction, reducing the possibility of misoperation. Moreover, the inclined surface design allows the user's fingers to be placed naturally on the removal part 220, providing a more ergonomic operating angle. On the other hand, the inclined surface provides a larger contact area, which can evenly distribute the pressure at the point of force application, making the disassembly process more effortless.

[0283] Referring to Figure 28, in one embodiment, one of the dust cover 200 and the nozzle body 100 is provided with a positioning member 140, and the other is provided with a positioning hole 240 for engaging with the positioning member 140. For example, in the embodiment shown in the figure, the positioning member 140 is provided at the end of the nozzle body 100 away from the handle 7, and the positioning hole 240 is provided at the end of the dust cover 200 away from the handle 7. The engaging cooperation between the positioning member 140 and the positioning hole 240 further enhances the connection effect between the dust cover 200 and the nozzle body 100, ensuring a stable connection between the two and improving the reliability of the cleaning equipment. In other embodiments, the positions of the positioning member 140 and the positioning hole 240 can be interchanged. It is understood that the extending direction of the positioning member 140 and the positioning hole 240 is parallel to the disassembly direction of the dust cover 200.

[0284] In one embodiment, an elastic element (not shown) connects the handle 7 and the first latching portion 310. Understandably, when the first dial portion 110 is in the locked position, i.e., when the first latching portion 310 is not subjected to external force, the elastic element is in its natural state. When the user applies force to the first dial portion 110 to disengage the first latching portion 310 from the second mating portion 210, the elastic element is in a deformed state. By providing the elastic element, a reset locking force is provided to the first latching portion 310, allowing it to automatically reset after the external force is removed, so as to connect with at least one of the first mating portion 120 and the second mating portion 210, ensuring the reliable connection between the handle 7, the nozzle body 100, and the dust cover 200. In some embodiments, the elastic element can be a spring.

[0285] Referring to Figures 22B and 23B, in one embodiment, the first engaging portion 310 includes a fixing section 311, a latching section 313, and an unlocking section 314. The fixing section 311 is connected to the handle 7, and the latching section 313 is used to connect with the first mating portion 120 and the second mating portion 210. One of the latching section 313 and the unlocking section 314 is connected to an elastic member. In response to the unlocking operation of the unlocking section 314, the latching section 313 can move to a second unlocking position to disengage from the first mating portion 120. In the embodiment shown in the figures, the elastic member is connected to the unlocking section 314, that is, the elastic member is located below the unlocking section 314. In other embodiments, the elastic member may also be connected to the latching section 313, that is, the elastic member is located below the latching section 313. Understandably, the fixed section 311 remains in the same position relative to the handle 7. By setting the unlocking section 314, a force application position is provided for the user, allowing the user to apply force to the unlocking section 314 so that the latching section 313 can move down to disengage from the first mating part 120, thereby releasing the connection between the nozzle body 100 and the handle 7.

[0286] In some embodiments, when the user applies the unlocking section 314 to move the latching section 313 to the second unlocking position and disengage it from the first mating part 120, the first toggle part 110 can still be engaged in the second mating part 210 of the dust cover 200, meaning that the dust cover 200 and the nozzle body 100 still have a certain connection effect. Thus, when the nozzle body 100 and the handle 7 are disconnected, the dust cover 200 and the nozzle body 100 will not fall apart, reducing the risk of damage caused by accidental drop of the dust cover 200 or the nozzle body 100.

[0287] Referring to Figures 22B and 23B, in one embodiment, the latching segment 313 is located between the fixing segment 311 and the unlocking segment 314. In response to a pressing operation of the unlocking segment 314, the latching segment 313 can be disengaged from the first engaging portion 120. That is, the latching segment 313 and the unlocking segment 314 are located on the same side of the fixing segment 311. Thus, when the user presses down on the unlocking segment 314, it causes the latching segment 313 to move downwards and disengage from the first engaging portion 120. If the first latching part 310 is considered as a lever structure, then the fixed section 311 corresponds to the fulcrum end of the lever structure, and the unlocking section 314 and the latching section 313 correspond to the power end and the resistance end, respectively. Since the latching section 313 is located between the fixed section 311 and the unlocking section 314, that is, the resistance arm is smaller than the power arm, the user only needs to apply a small force to the unlocking section 314 to generate a large output force on the latching section 313, making the disassembly between the handle 7 and the nozzle body 100 easier and reducing user fatigue. In other embodiments, the latching section and the unlocking section can also be located on both sides of the fixed section. In this way, by lifting the unlocking section upward, the latching section can be moved downward to disengage from the first mating part.

[0288] Referring to Figures 22B and 23B, in one embodiment, at least one of the handle 7 and the unlocking segment 314 is provided with a first fixing part 333, which is used to fix the elastic member. In the embodiment shown in the figures, both the handle 7 and the unlocking segment 314 are provided with the first fixing part 333, wherein the first fixing part 333 can be a protruding limiting post or a recessed limiting groove. For example, in the embodiment shown in the figures, the unlocking segment 314 is provided with a limiting groove, the handle 7 is provided with a limiting post, one end of the elastic member is accommodated in the limiting groove, and the other end is sleeved on the limiting post. By setting the first fixing part 333 to limit the elastic member, the deformation direction of the elastic member is effectively constrained, thereby ensuring the reliability of the direction of the restoring force applied by the elastic member. In other embodiments, the first fixing part 333 may only be provided on one of the handle 7 and the unlocking segment 314 to limit one end of the elastic member, and the other end of the elastic member may be welded to the other of the handle 7 and the unlocking segment 314, which can be set according to actual needs.

[0289] Referring to Figures 22B and 23B, in some embodiments, the latching segment 313 is located between the fixing segment 311 and the unlocking segment 314. The first latching portion 310 also includes a bent segment 312 located between the fixing segment 311 and the latching segment 313, extending from the fixing segment 311 in a direction close to the elastic element. The bent segment 312 can provide a certain elastic deformation capacity, allowing the latching segment 313 to be finely adjusted in position as needed during insertion and removal, ensuring a tight fit with the first mating portion 120 and the second mating portion 210. Simultaneously, the bent segment 312 can also disperse the force applied to the latching segment 313, avoiding stress concentration. Furthermore, because the bent segment 312 provides better elasticity and recovery capacity, the latching segment 313 is less prone to permanent deformation or fracture during repeated use, exhibiting high fatigue strength. For example, in the embodiment shown in the figures, the bent segment 312 is U-shaped. The unlocking section 314 and the latching section 313 are designed as protruding latches. The shape and size of the latches can be set according to actual needs. For example, the protrusion height of the unlocking section 314 is greater than the protrusion height of the latching section 313. An accommodating groove for accommodating the first toggle part 110 is formed between the unlocking section 314 and the latching section 313.

[0290] Referring to Figure 23B, in some embodiments, the handle 7 is provided with a support structure 330 for supporting the first latching portion 310. The support structure 330 provides additional support points for the first latching portion 310, reducing the risk of loosening due to vibration or external forces, and ensuring a more secure connection between the first latching portion 310 and the nozzle body 100 and dust hood 200. Simultaneously, it allows the force on the first latching portion 310 to be distributed more evenly across the entire support structure 330, reducing localized stress concentration and thus lowering the risk of wear and fatigue damage.

[0291] Referring to Figure 23B, in one embodiment, the support structure 330 includes a support plate 331 and a support column 332 protruding from the support plate 331. The aforementioned first fixing part 333, which is provided on the handle 7, can be located on the support plate 331, and the aforementioned fixing segment 311 can be connected to the support column 332. In some embodiments, at least one of the support column 332 and the fixing segment 311 is provided with a connecting hole 3111, and the other is connected with a connector for inserting into the connecting hole 3111. For example, in the embodiment shown in the figures, both the support column 332 and the fixing segment 311 are provided with connecting holes 3111, and the connector passes through the connecting holes 3111 of both, thereby fixing the support column 332 and the first snap-fit ​​part 310. For example, the connecting hole 3111 is a pin hole, and the connector is a pin; or the connecting hole 3111 is a screw hole, and the connector is a screw, etc. In other embodiments, one of the support column 332 and the fixing section 311 may be configured with a connecting hole 3111, and the other may be configured with a connector that is inserted into the connecting hole 3111.

[0292] Referring to Figures 22B to 25, in one embodiment, the nozzle body 100 is provided with a second marking portion 191, and the handle 7 is provided with a first acquisition portion 6111 for identifying the second marking portion 191. Referring to Figures 22B and 23B, in one embodiment, one of the second marking portion 191 and the first acquisition portion 6111 is constructed as a male connector, and the other is constructed as a female connector for connection with the male connector. For example, the second marking portion 191 is a male connector, and the first acquisition portion 6111 is a female connector; of course, the second marking portion 191 can also be a female connector, and the first acquisition portion 6111 can be a male connector. In some embodiments, the male connector can be a PIN pin, and the female connector can be a PIN pin connection hole 3111. When the nozzle body 100 is connected to the handle 7, the PIN pin of the nozzle body 100 is connected to the PIN pin connection hole 3111 on the handle 7, and the information on the second marking portion 191 is read through the physical contact between the two, thereby realizing signal transmission.

[0293] In other embodiments, the second marking unit 191 can be a short-range communication module such as a QR code, NFC, RFID, or Bluetooth, and the first acquisition unit 6111 can be a reader or a receiver. For example, when the second marking unit 191 is a QR code, the first acquisition unit 6111 can use a camera or barcode scanner as a reader to read information and transmit signals; when the second marking unit 191 is NFC, the first acquisition unit 6111 can use a card reader as a reader; when the second marking unit 191 is RFID, the first acquisition unit 6111 can use an RFID reader as a reader; when the second marking unit 191 is Bluetooth, the first acquisition unit 6111 can use a Bluetooth receiver, etc., to read information and transmit signals.

[0294] Referring to Figures 22B or 34B, in one embodiment, the nozzle body 100 is configured with a first suction channel 130, a portion of which is inclined relative to the outer surface of the nozzle body 100. By inclining the portion of the first suction channel 130, abrupt changes in air direction within the channel can be reduced, avoiding unnecessary vibration and noise, and also helping to reduce friction and turbulence during airflow. Simultaneously, gravity can be used to help heavier particles slide down the channel, allowing the sucked-in air and particles to pass more smoothly, reducing the possibility of particle accumulation within the channel. Furthermore, it also reduces the risk of sucked-in particles flowing back to the surface being cleaned due to airflow changes, preventing contamination of the cleaned surface and ensuring a more thorough cleaning effect. For example, in the embodiment shown in the figures, the first suction channel 130 is in an inclined L-shape.

[0295] Referring to Figures 22B or 34B, in one embodiment, the dust hood 200 is configured with a negative pressure port 230 (i.e., the suction port of the aforementioned embodiment). After the nozzle body 100 and the dust hood 200 are connected, a portion of a first suction channel 130 communicating with the negative pressure port 230 is formed between them. The flow area of ​​the negative pressure port 230 is smaller than the flow area of ​​the first suction channel 130. When the gas flow rate is constant, the flow area is inversely proportional to the fluid velocity. By setting the flow area of ​​the negative pressure port 230 to be smaller than the flow area of ​​the first suction channel 130, the flow velocity at the negative pressure port 230 can be increased, meaning a stronger negative pressure zone can be formed at the negative pressure port 230, which helps to quickly suck in surrounding dust and particles, improving cleaning efficiency. Simultaneously, it also reduces the problem of wastewater flowing back from the negative pressure port 230 to the surface being cleaned, preventing contamination of the cleaned surface. In some embodiments, the flow area of ​​the negative pressure port 230 is less than 20% of the flow area of ​​the first suction channel 130.

[0296] Referring to Figures 34A to 25, in one embodiment, the nozzle body 100 has an opening 180, and an air inlet 170 is constructed on the edge of the outer peripheral surface of the nozzle body 100 near the opening 180. This allows air to enter the system from multiple directions, increasing the airflow inlet area and facilitating the collection of surrounding dust and debris to the negative pressure port 230, expanding the cleaning range and preventing secondary pollution; it also disperses airflow pressure, reduces local resistance, and thus improves overall suction efficiency.

[0297] Referring to Figures 34B to 36, in some embodiments, the nozzle body 100 has an opening 180, within which a brush holder 182 is disposed. Multiple tufts of bristles 181 are mounted on the brush holder 182, extending out of the opening 180 in a direction away from the handle 7, with an extension length of 1mm-3mm. In some embodiments, the brush holder 182 has multiple brush mounting holes 185, each with bristles 181 mounted on it. The protruding bristles 181 can better contact and penetrate into the texture or crevices of the surface being cleaned, such as carpet fibers and floor seams, removing stubborn stains and dust through physical friction, thus improving cleaning effectiveness. Furthermore, the bristles 181 help disperse airflow, allowing it to more evenly cover the entire cleaning area, improving cleaning efficiency. Furthermore, the protruding bristles 181 allow for a certain gap between the negative pressure port 230 and the surface being cleaned, thus providing a certain air intake. Therefore, additional air inlets 170 can be opened as needed, or no additional air inlets 170 can be provided.

[0298] In some embodiments, the length of the bristles 181 protruding relative to the nozzle body 100 can be 1 mm. In some embodiments, the length of the bristles 181 protruding relative to the nozzle body 100 can be 2.5 mm. In some embodiments, the length of the bristles 181 protruding relative to the nozzle body 100 can be 3 mm. In other embodiments, the length of the bristles 181 protruding relative to the nozzle body 100 can also be other values, which will not be listed here. Bristles 181 of different lengths can adapt to surfaces of different shapes and materials being cleaned, ensuring effective cleaning on various surfaces without damaging their appearance.

[0299] Referring to Figures 22B, 34B to 36, in some embodiments, the nozzle body 100 has an opening 180, within which a brush holder 182 is disposed. The brush holder 182 is provided with bristles 181, a steam injection hole 183 (i.e., a cleaning fluid injection hole), and a suction port 184 (i.e., the suction port in the aforementioned embodiments, which may include a negative pressure port and a suction port). The steam injection hole 183 is directly disposed on the brush holder 182, i.e., on the nozzle body 100. Therefore, after the nozzle body 100 is connected to the handle 7, only the sealing effect between the first steam channel 150 and the second steam channel 340 needs to be considered, reducing the number of sealing locations and sealing costs. High-temperature steam is released through the steam injection hole 183 to soften stains, while the bristles 181 located thereafter further decompose and remove stubborn stains through physical friction. Subsequently, the suction port 184 can quickly suck the loose dirt into the cleaning device, forming an effective cleaning cycle. By setting a dedicated suction port 184 on the nozzle body 100 and combining it with the negative pressure port 230 on the dust cover 200, suction can be generated at different locations, enabling the cleaning equipment to simultaneously suck up dirt from multiple directions, ensuring more comprehensive cleaning coverage. It can also make the airflow more evenly distributed in the cleaning area, avoiding over-cleaning or damage to the surface in some areas due to excessively concentrated airflow.

[0300] Referring to Figures 22B, 34B to 36, it can be understood that the steam injection port 183 is connected to the first steam channel 150 of the nozzle body 100, and the suction port 184 is connected to the first suction channel 130 of the nozzle body 100. When the nozzle body 100 and the handle 7 are connected, the first steam channel 150 is connected to the second steam channel 340 of the handle 7 (i.e., the first cleaning channel in the aforementioned embodiment); the first suction channel 130 is connected to the second suction channel 350 of the handle 7 (i.e., the first dirt channel in the aforementioned embodiment). Thus, the cleaning liquid provided by the spray unit in the cleaning equipment can pass through the second steam channel 340 and the first steam channel 150 in sequence, and then be sprayed onto the surface to be cleaned through the steam injection port 183. The cleaned dirt enters the first suction channel 130 through the negative pressure port 230 and the suction port 184 under the action of negative pressure suction, and then enters the wastewater collection unit of the cleaning equipment through the second suction channel 350. The flow area of ​​the suction port 184 is smaller than the fluid area of ​​the first suction channel 130. The smaller flow area of ​​the suction port 184 reduces the risk of wastewater flowing back to the surface being cleaned, preventing contamination of the fabric surface. Simultaneously, for particularly dirty or difficult-to-clean areas, the smaller flow area of ​​the suction port 184 can provide stronger localized suction, helping to more effectively remove stubborn stains or large pieces of debris.

[0301] Referring to Figures 22B, 34B to 36, in some embodiments, the bristles 181 are located between the steam jet hole 183 and the suction port 184. By positioning the bristles 181 between the steam jet hole 183 and the suction port 184, the bristles 181 can help guide the steam ejected from the steam jet hole 183 to a specific area, ensuring that the cleaning medium can directly act on the area that needs cleaning. Simultaneously, after the cleaning liquid is sprayed onto the surface being cleaned, it flows through the bristles 181 and then into the suction port 184, thereby removing dirt from the bristles 181, achieving self-cleaning of the bristles 181, reducing the possibility that dirt on the bristles 181 may affect the subsequent cleaning effect. Furthermore, the bristles 181 can help accelerate moisture evaporation after steam cleaning, speeding up the drying process.

[0302] Traditional cleaning equipment that can perform multiple cleaning functions has numerous components and cleaning parts, which not only takes up space but also requires users to pre-set cleaning scenes on the main unit, select appropriate cleaning heads, and choose a working mode before cleaning can begin, making the process rather cumbersome. Furthermore, since both cleaning scenes and cleaning heads rely on manual selection and settings, if the installed cleaning head does not match the set cleaning scene, the equipment will operate with inappropriate cleaning parameters, affecting not only the cleaning effect but also the performance and lifespan of the cleaning equipment.

[0303] Based on this, this application provides a cleaning control method applied to the control unit of a cleaning device. The cleaning device can be any of the cleaning devices described in the foregoing embodiments. The control unit can be detachably connected to any cleaning head via a handle. The method includes: the control unit responding to the connection with any cleaning head and obtaining the type information of the connected cleaning head; and responding to a mode selection command for a cleaning mode and determining a target mode; thereby determining cleaning parameters based on the type information of the cleaning head and the target mode, and performing a cleaning operation. The cleaning mode refers to the target flow rate and target power corresponding to different cleaning heads under the cleaning mode. This application only requires replacing the corresponding cleaning head in different cleaning scenarios to automatically identify the type of cleaning head and automatically match the required cleaning parameters based on the type of cleaning head and the user-selected working mode for cleaning in different scenarios. This eliminates the need for users to manually set cleaning scenarios, reducing the steps of manually selecting cleaning modes. This not only simplifies the usage process but also avoids problems such as the cleaning effect being affected by the mismatch between the user-installed cleaning head and the set cleaning scenario, as well as the performance and lifespan of the cleaning device. Therefore, it ensures cleaning effectiveness and improves the performance and lifespan of the cleaning device.

[0304] In one embodiment, the method may include the following steps: Step 102, in response to connection with any cleaning head, obtaining the type information of the connected cleaning head. A cleaning head is a specific cleaning component used to clean items. In this embodiment, different types of cleaning heads can be used to clean items in different scenarios, enabling the cleaning device to perform multiple cleaning functions. The cleaning heads, by type, may include, but are not limited to, steam fabric cleaning heads, steam window cleaning heads, tableware cleaning heads, kitchen stove cleaning heads, kitchen appliance cleaning heads (such as ovens, microwave ovens, refrigerators, etc.), shoe cleaning heads, clothing cleaning heads, floor cleaning heads, bathroom cleaning heads, car washing heads, etc. To facilitate the replacement of different types of cleaning heads for cleaning items in different scenarios, in this embodiment, the control unit of the cleaning device can be detachably connected to any cleaning head. In this embodiment, when any cleaning head is detachably connected to the control unit, the control unit can respond to the connection with that cleaning head and obtain the type information of the connected cleaning head based on that connection, in order to perform cleaning control through subsequent steps.

[0305] Step 104: In response to the mode selection command for the cleaning mode, determine the target mode. The cleaning mode of the cleaning equipment can include multiple modes, such as steam cleaning mode and vacuum drying mode. In steam cleaning mode, the cleaning fluid generator and the vacuum recovery device operate simultaneously; in vacuum drying mode, the cleaning fluid generator does not operate, but the vacuum recovery device operates. In this embodiment, the user can select different modes according to actual needs, thereby achieving switching between cleaning and vacuum drying modes to realize cleaning work under different modes. Based on this, the control unit can also respond to the user's mode selection command for the cleaning mode and determine the target mode. The target mode refers to the specific cleaning mode ultimately selected by the user, such as steam cleaning mode or vacuum drying mode.

[0306] Step 106: Determine cleaning parameters based on the cleaning head type information and the target mode, and execute the cleaning operation. The cleaning parameters can be specific parameter configurations of the cleaning equipment during the cleaning process. Cleaning parameters include, but are not limited to, cleaning temperature, throughput, and power. It is understood that for the same type of cleaning head, the cleaning parameters may differ in different cleaning modes; conversely, for different types of cleaning heads, the cleaning parameters may differ in the same cleaning mode. Therefore, in this embodiment, the control unit can determine the matching cleaning parameters based on the cleaning head type information obtained in the above steps and the determined target mode, and then execute the cleaning operation.

[0307] In the aforementioned cleaning control method, the control unit obtains the type information of the connected cleaning head in response to connection to any cleaning head, and determines the target mode in response to a mode selection command for the cleaning mode. Based on the cleaning head type information and the target mode, it determines the cleaning parameters and executes the cleaning operation. By simply replacing the corresponding cleaning head in different cleaning scenarios, it can automatically identify the type of cleaning head and automatically match the required cleaning parameters based on the cleaning head type and the user-selected cleaning mode for different scenarios. This eliminates the need for users to additionally set cleaning scenarios, simplifying the usage process and avoiding problems caused by incompatibility between the user-installed cleaning head and the set cleaning scenario, which can affect cleaning effectiveness and the performance and lifespan of the cleaning equipment. This ensures cleaning effectiveness and improves the performance and lifespan of the cleaning equipment.

[0308] In one embodiment, each cleaning head may have a corresponding type identifier; then, as shown in FIG38, in step 102, in response to connection with any cleaning head, the type information of the connected cleaning head is obtained. Specifically, this may include:

[0309] Step 202: In response to connection with any cleaning head, obtain the type identifier of the connected cleaning head. The type identifier can be a unique mark or symbol characterizing the type of cleaning head. Since each cleaning head can have a corresponding type identifier, the type identifier of the connected cleaning head can be obtained when the control unit connects to any cleaning head. Specifically, the control unit can establish a communication connection with any cleaning head in response to a physical connection, thereby obtaining the type identifier of the connected cleaning head based on the communication connection. The communication connection method can include, but is not limited to, at least one of radio frequency communication, optical identification communication, and serial communication.

[0310] In one scenario, taking pin-based serial communication as an example, the control unit can have male pins, and the cleaning head can have female pins. The arrangement of the female pins differs across different types of cleaning heads; these different arrangements represent different type identifiers. As shown in Figure 39, taking an example where there are five male and five female pins respectively, with one male pin and one female pin used for grounding, the different arrangements of the other four female pins on the cleaning head can represent different type identifiers. As shown in Figure 40, for example, the arrangement of female pins on a certain cleaning head, "0001" (where "0" indicates a low level and "1" indicates a high level), represents the specific type identifier of the corresponding cleaning head, such as "Type 1." This type identifier uniquely identifies the type of cleaning head, such as a fabric cleaning head or a tableware cleaning head.

[0311] When any cleaning head is physically connected to the control unit (e.g., when the female pin of a cleaning head is plugged into the male pin of the control unit), the control unit can respond to this physical connection and establish a serial communication connection with the corresponding cleaning head based on the connected pin. Furthermore, since the pins on the cleaning head can be arranged in different combinations, and these different combinations represent different type identifiers, the control unit can also determine the type identifier of the connected cleaning head based on the different arrangements of the pins on the connected cleaning head and the corresponding serial communication.

[0312] In another scenario, taking NFC (Near Field Communication)-based radio frequency communication as an example, the control unit can generate a radio frequency field for NFC communication, and the cleaning head can have an NFC tag for recording the corresponding type identifier. Different types of cleaning heads record different type identifiers on their NFC tags. Therefore, when any cleaning head is physically connected to the control unit (e.g., when a cleaning head is connected to the control unit via a snap-fit ​​mechanism), the control unit can respond to this physical connection and establish NFC communication with the corresponding cleaning head, such as by generating a radio frequency field for NFC communication. The connected cleaning head can then transmit the type identifier recorded on the NFC tag to the control unit based on this radio frequency field, allowing the control unit to obtain the type identifier of the connected cleaning head.

[0313] Step 204: Determine the type information corresponding to the type identifier based on pre-stored configuration information. The configuration information may include a mapping relationship between the type identifier and type information of the cleaning head. For example, a mapping relationship between the type identifier "Type 1" and the type information "Fabric Cleaning Head," and a mapping relationship between the type identifier "Type 2" and the type information "Dishware Cleaning Head," etc. Therefore, the control unit can determine the type information corresponding to the determined type identifier of the cleaning head from the pre-stored configuration information, thereby obtaining the type information of the cleaning head.

[0314] In this embodiment, by automatically identifying the type identifier of the connected cleaning head and determining the type information corresponding to the type identifier based on the pre-stored configuration information, the automatic identification of the cleaning head type is achieved. This not only simplifies the user operation process and improves the convenience of use, but also avoids the situation where the cleaning effect is affected by the mismatch between the cleaning head installed by the user and the set cleaning scene, thus ensuring the cleaning effect.

[0315] In one embodiment, the configuration information may further include cleaning parameters corresponding to different modes under the type information. In step 106, determining the cleaning parameters based on the cleaning head type information and the target mode may specifically include: searching the configuration information for cleaning parameters that match the cleaning head type information and the target mode. Since the configuration information stores the mapping relationship between the cleaning head type identifier and the type information, as well as the cleaning parameters corresponding to different modes under the type information, the control unit, after obtaining the connected cleaning head type information and the user-selected target mode, can search the configuration information for cleaning parameters that match the cleaning head type information and the target mode, and then perform the cleaning operation based on the found cleaning parameters. This embodiment can automatically match appropriate cleaning parameters based on the identified connected cleaning head type information and the user-selected cleaning mode, thereby avoiding the risk of mismatched or unsuitable cleaning parameters caused by manually selecting the target mode, and thus ensuring the cleaning effect.

[0316] In one embodiment, the method may further include: receiving an update instruction for configuration information and updating the configuration information according to the update instruction. The update instruction may be an indication or command for modifying or updating the configuration information. For example, during product upgrades, if certain types of cleaning heads are no longer applicable and need to be phased out, an update instruction to delete the corresponding cleaning head type identifier can be sent to the control unit, thereby deleting the mapping relationship related to the corresponding cleaning head type identifier in the configuration information. If, during product upgrades, certain types of cleaning heads are added, or cleaning parameters are adjusted, etc., in order to enable the cleaning equipment to adapt to the new cleaning heads or new cleaning parameters, an update instruction to add or modify the corresponding cleaning head type identifier and its related configuration (such as the mapping relationship between the type identifier of the new cleaning head and type information, and the cleaning parameters corresponding to different modes under the type information) can be sent to the control unit, thereby adding or modifying the corresponding configuration in the configuration information. This improves the scalability of the cleaning equipment and increases its cleaning coverage.

[0317] In one embodiment, after obtaining the type information of the connected cleaning head, the method may further include: prompting the user with the type information of the cleaning head. Specifically, the control unit may display the type information of the cleaning head on a corresponding display interface, or it may broadcast the type information of the cleaning head via voice to prompt the user with the type information of the cleaning head. This embodiment, by prompting the user with the type information of the cleaning head, allows the user to understand the type of cleaning head currently in use in real time, avoiding incorrect use.

[0318] In one embodiment, after determining the target mode, the method may further include prompting the user with the target mode. Specifically, the control unit may display the target mode on a corresponding display interface, or it may announce the target mode via voice to prompt the user with the currently used target mode. This embodiment, by prompting the user with the target mode, allows the user to understand the currently used target mode in real time, avoiding incorrect mode usage.

[0319] In one embodiment, the method may further include issuing an abnormality alert when an abnormality is detected in the cleaning equipment. Abnormalities include, but are not limited to, situations affecting the normal operation of the cleaning equipment such as insufficient clean water tank, full wastewater tank, equipment tipping over, or components not being returned to their proper positions. Specifically, during the operation of the cleaning equipment, the control unit can monitor the status of the cleaning equipment in real time and issue an abnormality alert when an abnormality is detected. In this embodiment, the abnormality alert can be displayed on a corresponding display interface, or it can be indicated by status indicator lights (e.g., the indicator light is off or green when the equipment is working normally, and on or red when an abnormality is detected), or it can be broadcast via voice to inform the user of the abnormal situation. This embodiment allows users to understand the equipment's usage status in real time and promptly troubleshoot any abnormalities, thereby preventing equipment malfunctions from affecting the cleaning effect.

[0320] In one embodiment, each cleaning head may have a corresponding type identifier, and the type identifier may also contain type information and cleaning parameters corresponding to its different modes. The method may further include: in response to a connection with any cleaning head, establishing a communication connection with any cleaning head, obtaining the type information and cleaning parameters corresponding to its different modes from the type identifier of the connected cleaning head; in response to a mode selection instruction for a cleaning mode, determining the target mode and its corresponding cleaning parameters, and performing a cleaning operation. In this embodiment, to improve the efficiency of the control unit in finding matching cleaning parameters from a large amount of configuration information, and to save the cost of storing a large amount of configuration information in the control unit, the configuration information may not be stored in the control unit. Instead, the type information of the cleaning head and the cleaning parameters corresponding to its different modes may be carried in the type identifier corresponding to the cleaning head. Therefore, when the control unit is physically connected to any cleaning head, it can establish a communication connection with any cleaning head and obtain the type information and cleaning parameters corresponding to its different modes from the type identifier of the connected cleaning head. Then, when the user-selected target mode is obtained, the control unit can quickly determine the cleaning parameters corresponding to the target mode based on the data obtained from the connected cleaning head and perform a cleaning operation. This not only saves the cost of storing a large amount of configuration information in the control unit, but also improves the efficiency of the control unit in finding matching cleaning parameters from a large amount of configuration information.

[0321] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

[0322] Based on the same inventive concept, this application also provides a cleaning control handle for implementing the cleaning control method described above. The solution provided by this cleaning control handle is similar to the solution described in the above method; therefore, the specific limitations of one or more cleaning control handle embodiments provided below can be found in the limitations of the cleaning control method described above, and will not be repeated here.

[0323] In one embodiment, as shown in FIG41, a cleaning control handle is provided, including: a type acquisition module 502, a mode response module 504, and a parameter determination module 506. The type acquisition module 502 is configured to acquire the type information of the connected cleaning head when connected to the cleaning head; the mode response module 504 is configured to determine a target mode in response to a mode selection command for a cleaning mode; the parameter determination module 506 is configured to determine cleaning parameters based on the type information of the cleaning head and the target mode, and perform a cleaning operation. In one scenario, the parameter determination module 506 can also be integrated with the mode response module 504, thereby simplifying the hardware structure of the cleaning control handle.

[0324] In one embodiment, the cleaning head has a corresponding type identifier; the type acquisition module includes: an acquisition unit configured to acquire the type identifier of the connected cleaning head in response to a connection with any of the cleaning heads; and a determination unit configured to determine type information corresponding to the type identifier based on pre-stored configuration information, wherein the configuration information includes a mapping relationship between the type identifier and the type information of the cleaning head.

[0325] In one embodiment, the acquisition unit is further configured to: establish a communication connection with any of the cleaning heads in response to a connection with any of the cleaning heads, and acquire the type identifier of the connected cleaning head, wherein the communication connection method includes at least one of radio frequency communication, optical identification communication, and serial communication. In one embodiment, the configuration information further includes cleaning parameters corresponding to different modes under the type information; the determining unit is further configured to: search for cleaning parameters in the configuration information that match the type information of the cleaning head and the target mode.

[0326] In one embodiment, each cleaning head has a corresponding type identifier, which contains type information and cleaning parameters corresponding to its different modes. The parameter determination module is further configured to: establish a communication connection with any of the cleaning heads in response to a connection, obtain the type information in the type identifier of the connected cleaning head and the cleaning parameters corresponding to its different modes; and determine the target mode and corresponding cleaning parameters in response to a mode selection instruction for a cleaning mode, and perform a cleaning operation. In one embodiment, the cleaning control handle further includes a configuration update module, which is configured to: receive an update instruction for the configuration information and update the configuration information according to the update instruction. In one embodiment, the cleaning control handle further includes a prompting module, which is configured to: prompt the user with the type information and / or target mode of the cleaning head; or, issue an abnormality prompt when an abnormality is detected.

[0327] The various modules in the aforementioned cleaning control handle can be integrated onto a single control board or distributed across different control boards. Each module can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in hardware within or independently of the processor in a computer device, or stored in software within the computer device's memory, allowing the processor to invoke and execute the corresponding operations.

[0328] Based on the same inventive concept, this application also provides a cleaning head. The solution provided by this cleaning head is similar to the solution described in the above-described method, and will not be repeated here. In one embodiment, a cleaning head is provided, which is configured with a type identifier. This type identifier is used to establish a communication connection with a cleaning device and to provide feedback on the type information of the cleaning head. In one embodiment, the type identifier may also be configured with type information and cleaning parameters corresponding to its different modes, so as to provide feedback on the type information of the cleaning head and the cleaning parameters corresponding to its different modes to the cleaning device.

[0329] Based on the same inventive concept, this application also provides a cleaning device. The solution provided by the cleaning device is similar to the solution described in the above method. Therefore, the specific limitations of one or more cleaning device embodiments provided below can be found in the limitations of the cleaning control method above, and will not be repeated here.

[0330] In one embodiment, a cleaning device is provided, the cleaning device including a cleaning control handle as shown in FIG41 and the plurality of cleaning heads described above, wherein the cleaning control handle is detachably connected to any of the cleaning heads.

[0331] Specifically, as shown in Figure 42, the cleaning device of this application is further described below, including a cleaning head for moving over the surface of an item to be cleaned. The cleaning head is equipped with a type identifier, for example, a passive cleaning head identification PCB board 1 carrying pins. A cleaning control handle, connected to the cleaning head via a detachable interface, may include a type acquisition module (e.g., an active cleaning head identification PCB board 2 with pins), a mode response module (e.g., a handle control PCB 3), and a parameter determination module (e.g., a main control PCB 4 storing configuration information). The PCB board 1 / 2 with pins has at least two pins, one grounded and the other forming a signal to transmit the type information of the cleaning head. A cleaning system includes a cleaning fluid generator and a vacuum recovery device. A user interface may include a first user interface and a second user interface. The first user interface, as shown in Figure 43A, is used for mode prompts, such as displaying the cleaning head type and the cleaning mode of the cleaning device; the second user interface, located on the handle, as shown in Figure 43B, may include a cleaning mode input button and a status indicator light. Once the cleaning head and handle are connected, the first user interface will automatically display the type information corresponding to the cleaning head. Specifically, PCB 1 and PCB 2 are connected via male and female pins. The active cleaning head identification PCB 2 and the handle control PCB 3 are connected via a wire. The handle control PCB 3 can obtain the cleaning head type information through the connected PCB 1 / 2, and then transmit the identified signal to the main control PCB 4. The main control PCB 4 will then display the cleaning head type information on the first user interface. The first user interface can also be equipped with indicator lights to display abnormal machine statuses, such as low water level in the clean water tank, full wastewater tank, equipment tipping over, and handle not returning to its original position.

[0332] After selecting a cleaning mode (such as steam cleaning or vacuuming and drying) through the second user interface, the corresponding indicator light on the second user interface will remain lit to indicate the selected target mode. Simultaneously, the handle control PCB3 will transmit the target mode signal to the main control PCB4, which will then display the target mode on the first user interface. The main control PCB4 will automatically match cleaning parameters based on the cleaning head type information and the target mode, and execute cleaning operations such as spraying, vacuuming, and rubbing. For example, for a fabric cleaning head, if the target mode is steam cleaning, the main control PCB4 can find cleaning parameters such as cleaning temperature, throughput, and power that match the fabric cleaning head and steam cleaning mode. The main control PCB4 can also be equipped with an IoT (Internet of Things) module to update the cleaning head's configuration information via communication modes such as Wi-Fi / Bluetooth. It is understandable that the functions of PCBs 2, 3, and 4 can also be integrated onto a single PCB, thereby simplifying equipment design and maintenance.

[0333] Based on the same inventive concept, this application also provides a cleaning system. The solution provided by this cleaning system is similar to the solution described in the above method. Therefore, the specific limitations of one or more cleaning system embodiments provided below can be found in the limitations of the cleaning control method above, and will not be repeated here.

[0334] In one embodiment, the cleaning system may include a cleaning device as shown in FIG42 and at least one terminal device, wherein the terminal device and the cleaning device are connected via wired or wireless communication. Specifically, the cleaning device and / or the terminal device are configured to display a human-machine interface, obtain interactive commands for the cleaning device through the human-machine interface, and control the working mode of the cleaning device based on the interactive commands. The human-machine interface is also used to display the type information of the cleaning head of the cleaning device; or, display the target mode of the cleaning device; or, issue an abnormal prompt for the cleaning device. In one embodiment, the terminal device may be a mobile terminal or a device terminal for comprehensive control of the cleaning head and handle (such as a device loading the corresponding functions of PCB board 4), and this embodiment is not limited to this.

[0335] In one embodiment, a control device is provided, the internal structure of which can be shown in Figure 44. The control device includes a processor, a memory, an input / output interface, a communication interface, a display unit, and an input device. The processor, memory, and input / output interface are connected via a system bus, and the communication interface, display unit, and input device are also connected to the system bus via the input / output interface. The processor of the control device provides computing and control capabilities. The memory of the control device includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores an operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The input / output interface of the control device is used for exchanging information between the processor and external devices. The communication interface of the control device is used for wired or wireless communication with external components; wireless communication can be achieved through Wi-Fi, mobile cellular networks, Near Field Communication (NFC), or other technologies. When the computer program is executed by the processor, it implements a cleaning control method. The display unit of the control device is used to form a visually visible image and can be a display screen, a projection device, or a virtual reality imaging device. The display screen can be an LCD screen or an e-ink screen. The input device of the control device can be a touch layer covering the display screen, or buttons, trackballs, or touchpads set on the housing of the control device, or external keyboards, touchpads, or mice, etc.

[0336] Those skilled in the art will understand that the structure shown in FIG44 is only a block diagram of a part of the structure related to the present application and does not constitute a limitation on the control device to which the present application is applied. In one embodiment, the control device may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements.

[0337] Steam cleaners are devices that use high-temperature, high-pressure steam to clean the surface of objects. The structure and cleaning control process of traditional steam cleaners are shown in Figures 45 and 46. Traditional steam control methods suffer from unstable steam flow or temperature, which limits the application range of steam cleaners. Furthermore, because the heater operates at full power throughout the process, it results in high power consumption and serious waste of resources.

[0338] Based on this, this application provides a control method for the aforementioned cleaning equipment. As shown in Figure 47, the cleaning equipment may include a steam cleaner, a liquid pump (i.e., the second water pump in the aforementioned embodiment), a heater, a cleaning head, and a control unit. The liquid pump, heater, and cleaning head are connected sequentially via pipelines, and the control unit is communicatively connected to both the liquid pump and the heater. Different water flow rates and heater heating power are set based on different cleaning scenarios. The water flow rate is used to maintain stable flow and pressure in the steam pipeline, and the heater operates at a set power value using the heating power. This allows the steam flow rate and temperature to quickly reach dynamic equilibrium and remain stable over a long period under fixed water flow and heating power, thereby achieving optimal cleaning results. The liquid pump injects cleaning liquid, such as water, from a water source into the heater via pipelines. The water source can be a storage tank located within the cleaning equipment (e.g., the steam cleaner) or another water storage device located outside the cleaning equipment and connected to the liquid pump inlet via pipelines. The heater can specifically be a steam generator, used to heat the injected water to produce steam, and output the steam through a connected cleaning head. The cleaning head is a specific cleaning component that cleans the object being cleaned, and the steam is output through the cleaning head to clean the object being cleaned.

[0339] The control unit responds to the identified cleaning scenario, acquires the target flow rate and target power corresponding to the scenario, and controls the liquid pump to inject cleaning fluid (e.g., water) into the heater based on the target flow rate. It also controls the heater to heat the injected water using the target power to output cleaning steam for the target cleaning scenario. The cleaning scenario can be the specific situation in which the cleaning equipment is currently applied. For example, it can be the category of the object to be cleaned, such as clothes, curtains, tableware, kitchenware, floors, small appliances, etc. The cleaning scenario can also be the category of the cleaning heads currently installed on the cleaning equipment, such as fabric cleaning heads, window cleaning heads, tableware cleaning heads, kitchenware and stove cleaning heads, kitchen appliance (e.g., ovens, microwaves, refrigerators) cleaning heads, shoe cleaning heads, clothing cleaning heads, floor cleaning heads, bathroom cleaning heads, car washing heads, etc.

[0340] Target flow rate refers to the specific flow rate at which the liquid pump injects water into the heater under a given cleaning scenario. Target power, on the other hand, refers to the specific power value at which the heater operates under the same cleaning scenario. Since the required steam flow rate and temperature may differ for different cleaning scenarios, the control unit can obtain the target flow rate and target power corresponding to the identified cleaning scenario. Based on the target flow rate, it controls the liquid pump to inject water from the water source into the heater and controls the heater to heat the injected water using the target power. This ensures that the cleaning equipment operates at a fixed target flow rate and target power, thereby enabling the steam flow rate and temperature to quickly reach dynamic equilibrium and remain stable over a long period, achieving optimal cleaning results.

[0341] In one embodiment, during the process of the control unit controlling the liquid pump to inject water from the water source into the heater according to the target flow rate, the liquid pump can be subjected to open-loop power modulation based on the target flow rate, so that the liquid pump injects water into the heater at the target flow rate based on power modulation. Here, power modulation essentially adjusts the input power of the liquid pump, thereby changing its rotational speed or duty cycle, ultimately controlling the water flow rate. Specifically, power modulation can include at least one of pulse width modulation (PWM) and pulse frequency modulation (PFM). PWM controls the output voltage or power by adjusting the pulse width of a signal. Its basic principle is to use binary signals (high or low level) to control switching elements (such as transistors or MOSFETs), which switch between on and off at a high rate. When the switch is on, the load receives power; when the switch is off, the load is disconnected from the power supply. By adjusting the ratio of the switch's on time to the total cycle time (i.e., the duty cycle), the average voltage or power applied to the load can be effectively controlled. The larger the duty cycle, the higher the average voltage, the faster the liquid pump rotates, and the greater the water flow rate. Under ideal linear conditions, water flow rate is positively correlated with duty cycle. Therefore, the correspondence between target flow rate and duty cycle for different cleaning scenarios can be preset, and the duty cycle of the liquid pump can be adjusted based on this correspondence, allowing the liquid pump to quickly reach the target flow rate based on the modulated duty cycle. PFM, on the other hand, adjusts the total energy transferred per unit time by changing the frequency of the pulse signal (the number of pulses per unit time) while keeping the width of a single pulse fixed. Generally, the higher the frequency, the more energy input, the higher the liquid pump speed or working cycle, and the greater the water flow rate. Under a fixed pulse width, water flow rate is generally positively correlated with pulse frequency. Therefore, the correspondence between target flow rate and pulse frequency for different cleaning scenarios can be preset, and the pulse frequency of the liquid pump can be adjusted based on this correspondence, allowing the liquid pump to quickly reach the target flow rate based on the modulated pulse frequency, thus achieving rapid response. Since the above control method is not affected by the lag of temperature sensor measurement itself or whether it is accurately installed in a fixed position on the heater, nor by individual differences in the heater, the stability of the output steam flow rate can be ensured simply by adjusting the frequency of the liquid pump according to the target flow rate. Therefore, compared with the traditional method of control by temperature sensor, it can improve the stability of the output steam flow rate.

[0342] In one scenario, as shown in Figure 48, the cleaning equipment may further include a flow sensor, which can be installed at the inlet of the liquid pump and connected to the control unit. Specifically, a flow sensor is a device used to measure the flow rate or volume of a fluid (liquid or gas) in a pipe. For example, the flow sensor may include, but is not limited to, differential pressure flow sensors, turbine flow sensors, electromagnetic flow sensors, ultrasonic flow sensors, etc. During the process where the control unit controls the liquid pump to inject cleaning fluid (e.g., water) from the water source into the heater according to the target flow rate, the real-time flow rate at the liquid pump inlet can also be obtained through the flow sensor, and the difference between the real-time flow rate and the target flow rate can be calculated. Then, based on the calculated difference, closed-loop power modulation is applied to the liquid pump to allow it to inject cleaning fluid into the heater at the target flow rate. The power modulation can employ at least one of PWM and PFM, which will not be elaborated further in this embodiment. The difference lies in that this embodiment can perform closed-loop modulation control of the liquid pump based on the difference between the real-time flow rate collected by the flow sensor and the target flow rate, thereby gradually bringing the actual flow rate closer to the target flow rate and improving the accuracy of flow control.

[0343] In one embodiment, during the process of the control unit controlling the heater to heat the injected cleaning fluid at a target power to output clean steam for the target cleaning scenario, the heater can also be power-modulated based on the target power to make the heater operate at the target power and output clean steam for the target cleaning scenario. The power modulation of the heater can also employ at least one of the aforementioned PWM and PFM methods, and can be either open-loop or closed-loop modulation; this embodiment does not limit this. In one embodiment, the modulation process is similar to the modulation process of the liquid pump described above, and will not be elaborated further in this embodiment. The above control method, by identifying the target power of the cleaning scenario and adjusting the heater to a fixed power, can ensure the stability of the output steam temperature and provide a rapid response. Compared to the traditional method of operating at full load, it can also save power consumption and reduce energy consumption. After obtaining the target flow rate and target power corresponding to the cleaning scenario, the control unit can also respond to the cleaning command for the object being cleaned, control the heater to operate to preheat the heater, and obtain the preheating temperature of the heater through a temperature sensor installed on the heater. When the preheating temperature reaches the set temperature threshold, the liquid pump is controlled according to the target flow rate to inject the cleaning fluid from the water source into the heater. The cleaning command can be an instruction or command used to control the cleaning equipment to start working. Specifically, it can be a voice command or an instruction sent via a switch button on the cleaning equipment. The temperature threshold can be a preset target value for preheating temperature. In this embodiment, a temperature sensor is installed on the heater to detect the preheating temperature in real time. When the preheating temperature reaches the set temperature threshold, the liquid pump is controlled to inject cleaning fluid from the water source into the heater according to the target flow rate. This embodiment uses a preheating mechanism to rapidly heat the heater and internal pipes, thereby ensuring efficient and stable operation of the equipment, while also helping to protect the equipment and reduce operating costs.

[0344] In one embodiment, the process of a cleaning device identifying a cleaning scenario may include: responding to an identification command for the object being cleaned, the identification command carrying the category of the object being cleaned; and determining the corresponding cleaning scenario based on the category of the object being cleaned. The identification command may be an instruction or command given to the cleaning device before it performs a cleaning task, instructing it to identify the cleaning scenario. Specifically, it may be a voice command; or it may be a command sent via a switch button on the cleaning device. In this embodiment, the command may carry the category of the object being cleaned. For example, if the identification command is a voice command, the voice command can carry the category of the object being cleaned, such as clothes, curtains, tableware, kitchenware, floors, small appliances, etc., so that the corresponding cleaning scenario can be quickly determined based on the identification command. If the identification command is a command sent via a switch button on the cleaning device, different switch buttons can be set for different categories of the object being cleaned, or different operating modes of the same switch button can correspond to different categories of the object being cleaned. Therefore, the corresponding cleaning scenario can be identified based on different switch buttons or different operating modes of the same switch button, achieving flexible identification of different cleaning scenarios.

[0345] In one embodiment, the category identification component can be an image acquisition component. Driven by an identification command, it can acquire images of the object to be cleaned based on image recognition technology. The control unit then performs image recognition on the image of the object to identify its category, thereby determining the corresponding cleaning scene and achieving automatic identification of different cleaning scenes. In another embodiment, the category identification component can be an infrared detection component. Driven by an identification command, it can detect the heat distribution of the object to be cleaned based on infrared recognition technology. The control unit then analyzes the heat distribution of the object to identify its category, thereby determining the corresponding cleaning scene and achieving automatic identification of different cleaning scenes.

[0346] The cleaning scenario identifier can be a unique mark or symbol representing the cleaning scenario to which the cleaning head is applied, such as a fabric cleaning head or a dish cleaning head. Therefore, each cleaning head can be used for a cleaning scenario in one embodiment and has a corresponding cleaning scenario identifier. In this embodiment, the cleaning head can be movably connected to the steam output port of the heater, facilitating the replacement of the cleaning head to adapt to different cleaning scenarios. Specifically, when the steam output port of the heater is connected to any cleaning head, the control unit can respond to the connection to obtain the cleaning scenario identifier of the connected cleaning head, thereby determining the corresponding cleaning scenario based on the cleaning scenario identifier of the connected cleaning head, thus achieving automatic identification of different cleaning scenarios. Of course, each cleaning head can also have a corresponding type identifier, which can be a unique mark or symbol representing the type of cleaning head. Since each cleaning head can have a corresponding type identifier, when the control unit connects to any cleaning head via the handle, it can obtain the type identifier of the connected cleaning head. Specifically, the control unit can achieve a physical connection with any cleaning head via the handle and establish a communication connection with the corresponding cleaning head, thereby obtaining the type identifier of the connected cleaning head based on the communication connection.

[0347] In one embodiment, the cleaning scene identifier or type identifier may further include corresponding flow rate and power. The control unit then obtains the target flow rate and target power corresponding to the cleaning scene, specifically including: obtaining the flow rate and power from the cleaning scene identifier or type identifier of the connected cleaning head, and using them as the target flow rate and target power corresponding to the cleaning scene. That is, obtaining the flow rate from the cleaning scene identifier or type identifier of the currently connected cleaning head as the target flow rate for the current cleaning scene, and obtaining the power from the cleaning scene identifier or type identifier of the currently connected cleaning head as the target power for the current cleaning scene. This achieves rapid acquisition of the target flow rate and target power corresponding to the cleaning scene. Alternatively, the target flow rate and target power corresponding to the cleaning scene can be determined based on pre-stored configuration information.

[0348] The configuration information includes at least one mapping relationship between cleaning scenarios and flow rate and power. For example, as shown in Table 1, there is a mapping relationship between the cleaning scenario "tableware" and the flow rate "A1" (unit: ml / min, i.e., A1 milliliters per minute) and the power "B1" (unit: W, i.e., watts), and a mapping relationship between the cleaning scenario "fabric" and the flow rate "A3" (unit: ml / min, i.e., A3 milliliters per minute) and the power "B3" (unit: W, i.e. watts). Therefore, the control unit can determine the target flow rate and target power corresponding to the identified cleaning scenario from the pre-stored configuration information, and inject cleaning fluid, such as water, into the heater according to the target flow rate. The control unit controls the heater to heat the injected cleaning fluid using the target power, thereby outputting clean steam for the target cleaning scenario to ensure the cleaning effect under different scenarios.

[0349] Table 1:

[0350] In one embodiment, as shown in Figures 48 and 49, the control logic of the cleaning equipment described above is further explained below. In this embodiment, a flow sensor is used in the water circuit instead of a traditional level sensor. Under different cleaning scenarios, the flow rate and steam pressure in the steam pipeline are kept stable by setting a target flow rate value for the water circuit. The liquid pump operates by adjusting the pressure according to the set target flow rate through an AC chopper circuit control method, thereby ensuring stable steam flow output. The temperature sensor in the heater does not participate in steam temperature control; it only monitors the preheating temperature when the equipment is first turned on for preheating. After preheating, the function of the temperature sensor ends. When steam cleaning is running, depending on the cleaning scenario (such as different types of objects being cleaned or different types of cleaning heads installed), the control unit adjusts the voltage of the heater through an AC chopper circuit control method, such as PWM control, by adjusting the duty cycle of the PWM signal to control the bidirectional thyristor circuit. After voltage adjustment, the heater power will operate at a fixed value (i.e., the target power corresponding to the cleaning scenario). At this time, the fixed water flow rate and the fixed operating power of the heater dynamically and quickly reach equilibrium, ensuring that the steam flow rate and temperature at a certain pressure remain stable and achieving the best cleaning effect. This enables the stabilization of steam flow and temperature in various application scenarios, thus expanding the application range of cleaning equipment.

[0351] Furthermore, the control method in this embodiment is unaffected by the lag in temperature sensor measurement, the accuracy of its installation in the heater's fixed position, or individual differences in the heater. By simply setting the water flow rate and adjusting the heater's output voltage duty cycle, the stability of steam flow and temperature can be ensured. Compared to traditional control methods, this embodiment offers faster time response and more stable steam flow and temperature control. As shown in Figure 50, the curve with rectangular sampling points represents the temperature operation curve under this embodiment's control method, while other curves represent the control method that adjusts the liquid pump flow rate through temperature feedback. The horizontal axis represents time (in seconds, S), and the vertical axis represents temperature (in degrees Celsius, °C). Moreover, since the heater in this embodiment operates at a fixed power corresponding to the cleaning scenario, compared to full-load operation in traditional technologies, power consumption is significantly reduced, thus effectively saving energy.

[0352] Based on the same inventive concept, this application also provides a control method applied to the aforementioned cleaning equipment, such as a steam cleaner. The solution provided by this method is similar to the solution described in the aforementioned equipment; therefore, the specific limitations in one or more control method embodiments provided below can be found in the limitations of the cleaning equipment described above, and will not be repeated here.
