Cleaning apparatus

Abstract

The application relates to a cleaning device. After a user finishes cleaning a cleaning surface, the user can plug a cleaning unit, such as a handle or a cleaning head, into a self-cleaning unit, so that the cleaning device can enter a self-cleaning mode, thereby flushing dirt attached to the walls of a recovery pipeline, such as a dirt channel, and achieving the flushing and cleaning of the recovery pipeline walls. The user does not need to additionally attach a cleaning cover or other accessories, thereby reducing the user's operation steps, achieving the storage of the handle or the cleaning head while achieving the self-cleaning of the recovery pipeline of the cleaning device. Since no additional accessories need to be provided, the risk of accessory loss can be reduced, and the use cost of the accessories can be reduced. When the handle or the cleaning head is inserted into the self-cleaning unit, a closed space is formed between the self-cleaning unit and the handle or the cleaning head, which effectively reduces the possibility of overflow of the cleaning source, reduces the cleaning workload of the user, and improves the utilization rate of the cleaning source.

Wet surface cleaning equipment typically includes a cleaning source supply unit for supplying the cleaning source, a cleaning handle for spraying the cleaning source, and a wastewater collection unit for extracting the cleaned liquid and debris (which may include dirt, dust, stains, soil, hair, and other debris). After cleaning, the cleaning handle and the wastewater collection unit's recovery lines need to be cleaned to prevent dirt adhering to the walls of the recovery lines from affecting the suction power of the cleaning equipment.

[0082] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0083] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0084] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0085] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0086] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0087] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0088] After the cleaning equipment has finished cleaning the surface, the cleaning handle and the wastewater collection unit's recovery pipeline need to be cleaned to prevent dirt adhering to the pipeline walls from affecting the equipment's suction power. In related technologies, a detachable accessory, such as a cleaning cap, is installed on the cleaning head of the cleaning handle. The cleaning agent is sprayed from the cleaning head onto the cap, and then collected by the wastewater collection unit, achieving self-cleaning of the recovery pipeline. However, this method can cause cleaning agent overflow, increasing the cleaning workload, and the accessory is prone to loss.

[0089] Based on this, one embodiment of this application provides a cleaning device that can solve the above-mentioned problems. The cleaning device provided by one embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0090] See Figures 1 to 3 as well as Figure 11 As shown, an embodiment of this application provides a cleaning device including a main unit 100 and a cleaning unit. The main unit 100 is provided with a cleaning source supply unit (i.e., a spraying unit) and a sewage collection unit 4 (i.e., a waste collection unit). The main unit 100 is also provided with a self-cleaning unit. The cleaning unit is provided with a spaced cleaning channel and a waste channel. The cleaning channel is connected to the cleaning source supply unit to spray cleaning source through the outlet of the cleaning channel. The waste channel is connected to the sewage collection unit to suck up waste through the inlet of the waste channel. In a first state, the cleaning unit is detachably connected to the self-cleaning unit, and the outlet of the cleaning channel and the inlet of the waste channel are both located in the self-cleaning unit, so that the cleaning device can enter the self-cleaning mode.

[0091] Thus, after cleaning the surface, the user can insert the cleaning unit, i.e., the handle 200 or the cleaning head 300, into the self-cleaning unit, enabling the cleaning device to enter self-cleaning mode. In self-cleaning mode, the cleaning source is sprayed through the cleaning channel, flowing within the waste channel to flush away dirt adhering to the walls of the waste channel and other recovery pipes, achieving rinsing and cleaning of the recovery pipe walls. The dirt is then collected by the wastewater collection unit. By incorporating a self-cleaning unit into the main unit 100, the handle 200 or cleaning head 300 can be inserted after use, allowing the cleaning device to enter self-cleaning mode. This eliminates the need for users to attach additional cleaning caps or other accessories, reducing user steps. Furthermore, it simultaneously achieves self-cleaning of the cleaning device's recovery pipes and allows for the storage of the handle 200 or cleaning head 300. Since no additional accessories are required, the risk of accessory loss is reduced, and the cost of accessory use is also reduced. At the same time, when the handle 200 or cleaning head 300 is inserted into the self-cleaning unit, a closed space is formed between the self-cleaning unit and the cleaning unit, which effectively reduces the possibility of overflow of cleaning source and recycled dirt, reduces the user's cleaning workload, and improves the utilization rate of cleaning source.

[0092] See Figures 1 to 3 As shown, in one embodiment, the cleaning unit is a handle 200, the cleaning channel is a first cleaning channel 210, and the dirt channel is a first dirt channel 220. The first cleaning channel 210 and the first dirt channel 220 are spaced apart within the handle 200. The first cleaning channel 210 is connected to a cleaning source supply unit to spray cleaning source through its outlet; the first dirt channel 220 is connected to a wastewater collection unit to suck up dirt through its inlet. The self-cleaning unit is a first slot constructed in the main unit 100. In a first state, the handle 200 is detachably connected to the first slot 111, and both the outlet of the first cleaning channel 210 and the inlet of the first dirt channel 220 are located within the first slot 111, 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.

[0093] See Figures 1 to 3 As shown, an embodiment of this application provides a cleaning device including a main unit 100 and a handle 200. The main unit 100 is provided with a cleaning source supply unit (not shown) and a waste collection unit (i.e., the wastewater collection unit of the aforementioned embodiment). The main unit 100 is provided with a first slot 111. The handle 200 is provided with a first cleaning channel 210 and a first waste channel 220 spaced apart. The first cleaning channel 210 is connected to the cleaning source supply unit to spray cleaning source through the outlet of the first cleaning channel 210. The first waste channel 220 is connected to the waste collection unit to suck up waste through the inlet of the first waste channel 220. In a first state, the handle 200 is detachably connected to the first slot 111, and the outlet of the first cleaning channel 210 and the inlet of the first waste channel 220 are both located in the first slot 111, so that the cleaning device can enter a self-cleaning mode. It can be understood that the first state corresponds to the cleaning device being in a non-cleaning mode, that is, a state in which the cleaning device does not need to clean the surface to be cleaned.

[0094] Thus, after cleaning the surface, the user can insert the handle 200 into the first slot 111 of the main unit 100, and the cleaning device can enter the self-cleaning mode. In the self-cleaning mode, the cleaning device sprays cleaning source through the outlet of the first cleaning channel 210. Under the negative pressure suction of the waste collection unit, the cleaning source enters the first waste channel 220 and flows within it, thereby flushing down the dirt adhering to the walls of the first waste channel 220 and other collection pipes, achieving rinsing and cleaning of the collection pipe walls. Then, the dirt is collected by the waste collection unit. By setting the first slot 111 in the main unit 100, the handle 200 can be directly inserted into the first slot 111 after use, and the cleaning device can enter the self-cleaning mode without the need for the user to attach additional cleaning accessories such as cleaning caps, reducing the user's operation steps. Moreover, while achieving self-cleaning of the cleaning device's collection pipes, it also allows for the storage of the handle 200. 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 200 is inserted into the first slot 111, a closed space is formed between the first slot 111 and the handle 200, which effectively reduces the possibility of overflow of cleaning sources and recycled dirt, thus reducing the user's cleaning workload and improving the utilization rate of cleaning sources.

[0095] See Figure 2 As shown, in one embodiment, when the handle 200 is connected to the first slot 111, a first gap exists between the outer peripheral surface of the handle 200 and the side wall of the first slot 111 along the radial direction of the handle 200. 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 source to enter the first waste channel 220 under the negative pressure suction of the waste collection unit, thereby flushing and cleaning the wall of the collection pipeline. In one embodiment, the first gap 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. Moreover, the introduction of outside air helps to dilute and disperse the waste, making it easier for the waste to be transferred to the waste collection unit.

[0096] See Figure 2 , Figure 4 and Figure 5As shown, in one embodiment, one of the handle 200 and the first slot 111 is provided with a first marking part 230, and the other is provided with a first acquisition part 1111. In response to the connection between the handle 200 and the first slot 111, the first acquisition part 1111 can identify the first marking part 230, and the cleaning device enters a self-cleaning mode or a standby self-cleaning mode. When the handle 200 is inserted into the first slot 111, the first acquisition part 1111 identifies the first marking part 230 and transmits the signal of the handle 200 insertion to the control unit of the cleaning device. This allows the cleaning device to accurately determine whether the handle 200 has been correctly inserted back into the first slot 111, 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 source is sprayed out through the first cleaning channel 210. The cleaning source flows within the first waste channel 220, thereby flushing off the dirt adhering to the walls of the recovery pipes, achieving rinsing and cleaning of the recovery pipe walls. The dirt is then recovered by the waste recovery 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 source, improves fluid utilization efficiency, and reduces the user's cleaning workload.

[0097] See Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the first marking part 230 is disposed on the handle 200, and the first collecting part 1111 is disposed on the main unit 100. Besides cooperating with the first collecting part 1111 to enable the cleaning device to enter self-cleaning mode, in some embodiments, the first marking part 230 stores type information of the handle 200. When the handle 200 is inserted into the first slot 111 of the main unit 100, the first collecting part 1111 can identify the first marking part 230 and transmit a signal to the control unit of the cleaning device. The control unit can identify the type information of the handle 200 based on this signal, and thus adjust the operating parameters of the cleaning device accordingly, such as adjusting the suction force or suction power. In other embodiments, the first collecting part can be disposed on the handle, and the first marking part on the main unit.

[0098] See Figure 2As shown, in one embodiment, one of the first marking part 230 and the first acquisition part 1111 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 230 is a male connector and the first acquisition part 1111 is a female connector; of course, the first marking part 230 can also be a female connector and the first acquisition part 1111 can be a male connector. In some embodiments, the male connector can be a pin, and the female connector can be a pin connector hole. When the handle 200 is inserted into the first slot 111, the pin on the handle 200 connects to the pin connector hole on the host 100, and the information on the first marking part 230 is read through the physical contact between the two, thereby realizing signal transmission.

[0099] In other embodiments, the first tagging unit 230 can be a short-range communication module such as a QR code, NFC, RFID, or Bluetooth, and the first acquisition unit 1111 can be a reader or a receiver. For example, when the first tagging unit 230 is a QR code, the first acquisition unit 1111 can use a camera or barcode scanner as a reader to read information and transmit signals; when the first tagging unit 230 is NFC, the first acquisition unit 1111 can use a card reader as a reader; when the first tagging unit 230 is RFID, the first acquisition unit 1111 can use an RFID reader / writer as a reader; when the first tagging unit 230 is Bluetooth, the first acquisition unit 1111 can use a Bluetooth receiver or the like to read information and transmit signals.

[0100] In one embodiment, at least one of the main unit 100 and the handle 200 is provided with an operating element (not shown). In a first state, in response to a selection operation by the operating element, the cleaning device is in a self-cleaning mode. In some embodiments, the operating element may be located on the main unit 100, for example, the operating element may be a self-cleaning button located on the main unit 100. When the handle 200 is inserted into the first slot 111, the user presses the self-cleaning button on the main unit 100 to enable the cleaning device to enter the self-cleaning mode. Of course, in other embodiments, the operating element may also be a self-cleaning button integrated on the handle 200. 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 100 or the handle 200 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 200 is inserted into the first slot 111, the user clicks the operating element to enable the device to enter the self-cleaning mode.

[0101] Understandably, in some embodiments, an operating component may not be provided, and the cleaning device automatically enters the self-cleaning mode when the handle 200 is inserted into the first slot 111 of the main unit 100.

[0102] See Figure 1 and Figure 3 As shown, in one embodiment, the main unit 100 is provided with a mounting base 110, which has a first slot 111. By connecting the handle 200 to the main unit 100 using the mounting base 110, the mounting base 110 provides additional support without occupying internal space of the main unit 100. In one embodiment, the mounting base 110 can be located on the side of the main unit 100 in the horizontal direction. This arrangement makes the insertion position of the handle 200 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 200. In some embodiments, the mounting base 110 and the main unit 100 can be integrally formed. Of course, in other embodiments, the mounting base 110 can also be detachably connected to the main unit 100 as an independent module via threaded connection, snap-fit ​​connection, or magnetic connection, thus facilitating the maintenance and replacement of the mounting base 110.

[0103] See Figure 1 and Figure 3 As shown, in one embodiment, the mounting base 110 is constructed with a stop plate 112 extending along the direction of gravity. A second gap exists between the stop plate 112 and the horizontal side of the main unit 100, forming a storage groove 113. Thus, when the handle 200 is inserted into the first slot 111, connecting pipes, such as those connecting the main unit 100 and the handle 200, and control wiring harnesses, such as power lines and control lines, can be neatly wound around the mounting base 110, i.e., accommodated within the storage groove 113. This improves aesthetics and reduces the risk of tangling. Simultaneously, storing the pipes and control wiring harnesses within the storage groove 113 saves space. The stop plate 112 can block and limit the pipes and control wiring harnesses, preventing them from detaching from the storage groove 113 horizontally. In some embodiments, the stop plate 112 can be symmetrical in shape, facilitating its manufacturing.

[0104] like Figure 1 and Figure 2 As shown, in some embodiments, the mounting base 110 is provided with heat dissipation holes 114. The heat dissipation holes 114 allow heat to be dissipated through airflow, increasing the airflow around the mounting base 110, which helps to remove heat, improve its heat dissipation performance, prevent overheating, and thus prevent the insulation layer or pipes of the control harness wrapped on the mounting base 110 from aging or melting due to high temperature, thereby extending the service life of the control harness, pipes and the entire cleaning equipment.

[0105] In one embodiment, the cleaning device further includes a receiving tube for accommodating at least one of the first cleaning channel 210, the first waste channel 220, and the control harness of the cleaning device. The receiving tube is retractable into a receiving groove 113. By housing the pipes and control harness within the receiving tube, the tube provides protection, reducing the chance of the pipes 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 113.

[0106] See Figure 6 and Figure 7 As shown, in one embodiment, the cleaning device includes at least one cleaning head 300 detachably connected to the handle 200; that is, different types of cleaning heads 300 can be connected to the handle 200, such as... Figure 6 The cleaning head 300 in the illustrated embodiment, or Figure 8 The cleaning head 300 shown in the embodiment can be any other type, which will not be listed here. Different types of cleaning heads 300 can be connected via a handle to suit different usage scenarios.

[0107] In some embodiments, the handle 200 is provided with a first acquisition unit 1111, and the cleaning head 300 is provided with a second marking unit (not shown). When the cleaning head 300 is connected to the handle 200, the first acquisition unit 1111 can recognize the second marking unit, and the cleaning device enters a cleaning mode matching the cleaning head 300. The second marking unit stores type information of the cleaning head 300. By recognizing the second marking unit through the first acquisition unit 1111, a signal is transmitted to the control unit of the cleaning device. The control unit can recognize the type information of the cleaning head 300 based on this signal, and then adjust the cleaning mode of the cleaning device accordingly, such as adjusting the suction force, suction power, or the temperature of the sprayed cleaning source, to match the actual usage scenario.

[0108] It should be noted that when the first marking part 230 in the aforementioned embodiment is disposed on the host 100, and the first collection part 1111 for identifying the first marking part 230 is disposed on the handle 200, the first collection part 1111 for identifying the second marking part and the aforementioned first collection part 1111 for identifying the first marking part 230 can refer to the same component. That is, when the cleaning head 300 is connected to the handle 200, the first collection part 1111 can identify the second marking part, and when the handle 200 is connected to the first slot 111 of the host 100, the first collection part 1111 can identify the first marking part 230. Of course, in other embodiments, the first collection part for identifying the second marking part and the aforementioned first collection part 1111 for identifying the first marking part 230 can also refer to different components. That is, at least two first collection parts 1111 are provided, with at least one first collection part 1111 for identifying the first marking part 230 and at least one first collection part for identifying the second marking part.

[0109] In some embodiments, one of the first acquisition unit 1111 and the second marking unit can be a PIN pin, and the other can be a PIN pin connection hole. For example, the second marking unit is a PIN pin, and the first acquisition unit 1111 is a PIN pin connection hole. When the cleaning head 300 is connected to the handle 200, the PIN pin is connected to the PIN pin connection hole, and the information on the second marking unit is read through the physical contact between the two to realize signal transmission. Of course, the second marking unit can also be a PIN pin connection hole, and the first acquisition unit 1111 can be a PIN pin. In other embodiments, the second marking unit can be a short-range communication module such as a QR code, NFC, RFID, or Bluetooth, and the first acquisition unit 1111 can be a reader or receiver to read information and transmit signals.

[0110] The cleaning head 300 and the handle 200 can be connected by thread, snap-fit, pin, or magnetic means, for example, in... Figure 6 In the illustrated embodiment, the cleaning head 300 and the handle 200 can be connected by a snap-fit ​​mechanism. For example, the cleaning head 300 may have a protruding elastic snap, and the handle 200 may have a slot. When the cleaning head 300 is fitted onto the handle 200, the elastic snap engages in the slot, thus securing the cleaning head 300 and the handle 200. The cleaning head 300 is provided with spaced nozzles 310 and negative pressure ports 320. The nozzles 310 are connected to the outlet of the first cleaning channel 210, and the negative pressure ports 320 are connected to the inlet of the first dirt channel 220. Thus, the cleaning source supply unit sprays cleaning source material onto the surface to be cleaned through the nozzles 310 of the cleaning head 300, cleaning the stains on the surface. The negative pressure port 320 generates negative pressure suction on the surface to be cleaned, allowing the dirt and wastewater generated during cleaning to be drawn into the dirt recovery unit through the negative pressure port 320 for collection.

[0111] See Figure 6 and Figure 7 As shown, in some embodiments, taking a cylindrical cleaning head 300 as an example, the nozzle 310 is located on the central axis of the cleaning head 300, and multiple negative pressure ports 320 are provided, which are arranged at intervals along the circumference of the nozzle 310. By arranging multiple negative pressure ports 320 around the outer circumference of the nozzle 310, the distribution of negative pressure suction on the surface being cleaned can be relatively uniform, thereby ensuring that the cleaning source ejected from the nozzle 310 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 source, making the cleaning more effective, and it can also make the overall structural layout of the cleaning head 300 more compact and adaptable to various surfaces being cleaned. In some embodiments, the negative pressure port 320 can be set as an arc shape, such as a circle, an ellipse, or an oblong shape.

[0112] In other embodiments, the negative pressure port may be located on the central axis of the cleaning head, and multiple nozzles may be arranged around the outer circumference of the negative pressure port, so that the cleaning source is relatively evenly distributed on the surface being cleaned, which can improve the cleaning effect.

[0113] like Figures 8 to 10 As shown, in some embodiments, the nozzles 310 can be arranged in a straight line, which allows for a larger flow rate and coverage area from the cleaning source, thus better meeting cleaning needs. Of course, the arrangement of the nozzles 310 is not limited to this, and can be configured according to actual usage requirements.

[0114] See Figures 6 to 7 As shown, in one embodiment, the cleaning head 300 is provided with a scraping portion 330 protruding relative to the nozzle 310. The scraping portion 330 is spaced apart from the nozzle 310, and at least a portion of the scraping portion 330 is covered by the cleaning source sprayed from the nozzle 310. By setting the scraping portion 330 to protrude relative to the nozzle 310 and the negative pressure port 320, on the one hand, the scraping portion 330 can scrape and contact the surface to be cleaned, achieving a physical cleaning effect. By moving or rotating the scraping portion 330 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 source is sprayed onto the surface to be cleaned, it is bounced up, flows through the scraping portion 330, and then enters the negative pressure port 320, thereby removing the stains from the scraping portion 330, thus achieving self-cleaning of the scraping portion 330 and reducing the possibility that stains on the scraping portion 330 will affect the subsequent cleaning effect.

[0115] In one embodiment, the scraping part 330 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 adapt to various application scenarios, such as cleaning tableware, kitchen appliances, fabrics, windows, shoes, and floors. When the scraping part 330 is a scraper blade, scraper blade, bristle brush, or roller brush, it can move back and forth or roll, repeatedly making physical contact with dirt during the cleaning process, thereby loosening the dirt. When the scraping part 330, such as the scraper blade, scraper blade, bristle brush, or roller brush, has been used for a long time, it can be removed from the cleaning head 300, and only the scraper blade, scraper blade, bristle brush, or roller brush consumables need to be replaced. Alternatively, the cleaning head 300, which is connected to the scraper blade, scraper blade, bristle brush, or roller brush, can be replaced entirely from the cleaning equipment. When the scraping part 330 is a scouring pad or cleaning ball, if the scraping part 330 is used for a long time, only the scouring pad or cleaning ball needs to be replaced, which improves the convenience of replacement, increases cleaning efficiency, and saves replacement costs.

[0116] See Figures 6 to 7 As shown, in one embodiment, the scraping part 330 can be a raised contact point, and multiple raised contact points can be provided, arranged circumferentially along the nozzle 310. Providing multiple contact points can further enhance the physical cleaning effect of the cleaning head 300, 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.

[0117] See Figures 8 to 10 As shown, in some embodiments, the scraping part 330 can be a straight scraper, which can be used to clean hard surfaces such as glass and countertops. The flow direction of the cleaning source sprayed from the nozzle 310 forms an angle of 5 to 30 degrees with the scraper. The cleaning source is sprayed onto the boundary line between the surface to be cleaned and the scraper. The liquid scraped off by the scraper can be collected by the negative pressure port 320, which also removes dirt from the scraper, thus achieving self-cleaning of the scraper. The number of scrapers can be one or more. For example, in the embodiment shown in the figure, there are two scrapers, increasing the scraping area and providing mutual support. In some embodiments, the negative pressure port 320 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.

[0118] In one embodiment, the cleaning source 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 source, 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 source, 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 source, the spray pressure can be increased, and the spray force can be improved, which is more effective for cleaning larger volumes of dirt. That is, the cleaning equipment is a steam cleaner, and the first cleaning channel 210 is the steam delivery pipe of the following embodiment.

[0119] 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 source supply unit in the cleaning equipment provides the cleaning source to the surface being cleaned through the cleaning head, thus cleaning the stains on the surface. After cleaning, the dirt is collected by the negative pressure suction generated by the dirt recovery unit through the negative pressure port.

[0120] In one embodiment, the cleaning source supply unit includes a water pump and a clean water tank for holding the cleaning source. One end of the water pump is connected to the clean water tank via a pipeline, and the other end is connected to the nozzle of the cleaning head via a pipeline. The water pump is electrically connected to a controller, which controls the operation of the water pump to deliver the cleaning source in the clean water tank to the nozzle via the pipeline, and then sprays the cleaning source onto the surface to be cleaned through the nozzle.

[0121] In some embodiments, the waste collection unit includes a negative pressure suction device and a wastewater tank for holding waste. One end of the negative pressure suction device is connected to the wastewater tank via a pipeline, and the other end is connected to a negative pressure port. The negative pressure suction device is electrically connected to a controller, which controls the negative pressure suction device to perform suction operations, drawing the waste removed from the cleaning surface through the negative pressure port into the wastewater tank. In one embodiment, the negative pressure suction device can be a vacuum pump.

[0122] In some embodiments, the cleaning equipment is a steam cleaner; please refer to [the relevant documentation]. Figure 16 The cleaning unit includes a cleaning head 300; the steam cleaner includes a steam generating unit 2 and a handle 200; the steam generating unit 2 includes a cleaning source supply unit; the cleaning head 300 is connected to the steam generating unit 2 and the wastewater collection unit 4 via the handle 200. Thus, the position and orientation of the cleaning head 300 can be conveniently adjusted by holding the handle 200, which helps improve the cleaning effect and efficiency.

[0123] In one embodiment, the handle 200 is provided with a first collection part 1111, and the cleaning head 300 is provided with a second marking part; the first collection part 1111 is a first sensing contact group 71, and the second marking part is a second sensing contact group, the first sensing contact group 71 being as follows: Figures 14 to 15 The cleaning head 300 is connected to the control unit 5. In use, the cleaning head 300 is connected to the handle 200, enabling the second sensor contact group and the first sensor contact group 71 to connect, allowing the first sensor contact group 71 to send an electrical signal to the control unit 5. The control unit 5 can then identify the type information of the cleaning head 300 based on the electrical signal and adjust the operating mode of the steam cleaner accordingly, so that the steam generating unit 2 and the wastewater collection unit 4 of the steam cleaner are in the corresponding operating mode.

[0124] In related technologies, a utility model patent with authorization announcement number CN217429883U discloses a cleaning device, which includes a main unit, a cleaning head, a spraying unit, a suction unit, a heating element, and a control unit. The cleaning head has a spray nozzle and a suction nozzle. The spraying unit is connected to the spray nozzle for spraying cleaning liquid onto the surface to be cleaned. The suction unit is connected to the suction nozzle for providing suction to remove dirt from the surface to be cleaned. The heating element heats the cleaning liquid to provide the spraying unit with a heated cleaning liquid or steam. The control unit controls the start and stop of the spraying unit and / or the suction unit, and adjusts the working mode of the cleaning device so that the spraying unit, suction unit, and heating element are in corresponding working states. Although this cleaning device can use a heating element to heat the cleaning liquid to provide steam, its heating method is only electric heating, that is, the heat source for generating steam is only electrical energy, resulting in a large consumption of electrical energy.

[0125] Based on this, one embodiment of this application provides a steam cleaner, please refer to... Figure 11 and Figure 14 Understood, the steam cleaner includes a cleaning head 300, a control unit 5, and a steam generation unit 2, a secondary heating unit 3, and a wastewater collection unit 4, all connected to the control unit 5. For example... Figure 13 As shown, the cleaning head 300 has a nozzle 310 and a suction port 12 (it can be seen that the suction port 12 is the negative pressure port 320 of the aforementioned embodiment); as Figure 12 and Figure 14 As shown, the steam generation unit 2 includes an interconnected liquid spraying unit 21 and an electric heater 22 (it can be seen that the liquid spraying unit 21 is the clean energy supply unit of the aforementioned embodiment); as Figure 14As shown, the auxiliary heating unit 3 and the electric heater 22 are connected in parallel to heat the cleaning fluid to provide steam for the spraying unit 21; the heat source of the auxiliary heating unit 3 is a clean heat source. The spraying unit 21 is connected to the nozzle 310 to spray steam onto the surface to be cleaned; the wastewater collection unit 4 is connected to the suction port 12 to suck up dirt or wastewater generated during cleaning; the control unit 5 controls the start and stop of the steam generating unit 2, the auxiliary heating unit 3, and the wastewater collection unit 4.

[0126] 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. During 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 cleaning needs and energy availability. Specifically, the control unit 5 can control the electric heater 22 to work and the auxiliary heating unit 3 to not work, using only electrical energy to heat the cleaning fluid and generate steam; it can also control the electric heater 22 to work and the auxiliary heating unit 3 to work simultaneously, using both electrical energy and clean energy to provide energy for steam generation; or it can control the electric heater 22 to not work and the auxiliary heating unit 3 to work, using only clean energy to provide energy for steam generation. Therefore, the steam cleaner provided in this embodiment can not only use electrical energy to provide energy for steam generation but also use clean heat sources, thereby relatively reducing the electrical energy consumption of steam cleaning operations, which is beneficial for saving electricity and reducing electricity costs.

[0127] It is worth noting that the auxiliary heating unit 3 is a clean heat source that heats the cleaning liquid to generate steam. It is a type of 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. It can be a renewable heat source, such as solar energy, or a waste heat source. This application does not limit this.

[0128] 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.

[0129] In some embodiments, the auxiliary heating unit 3 is used to provide steam, hot water or hot air to the spraying unit 21.

[0130] Please refer to this as well. Figure 15 , Figure 15This is a schematic diagram of the structure of a steam cleaner according to another embodiment of this application. In actual installation, the specific structure of the auxiliary heating unit 3 is not limited.

[0131] In one embodiment, the auxiliary heating unit 3 is used to provide steam to the spraying unit 21 as an example.

[0132] In one embodiment provided in this application, please refer to Figure 14 It is understood that the auxiliary heating unit 3 includes an auxiliary heater 31, which is connected in parallel with an electric heater 22. That is, the liquid inlet and liquid outlet of the auxiliary heater 31 can be connected to the pipes connected to the liquid inlet and liquid outlet of the electric heater 22, respectively.

[0133] It is easy to understand that the auxiliary heater 31 is a heater capable of using a clean heat source to heat the cleaning fluid to generate steam. Figure 14 In the embodiment shown, 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 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. The electric heater 22 can even be turned off, so that the cleaning fluid only passes through the auxiliary heater 31, and only the clean heat source is used to provide energy for steam generation, thereby saving a large amount of electricity consumption for steam cleaning.

[0134] In one embodiment, the auxiliary heating unit 3 is used to provide hot water to the spraying unit 21.

[0135] In another embodiment provided in this application, please refer to Figure 15 Understandably, 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. Specifically, 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, and the heat exchanger 34 and the electric heater 22 are connected in parallel.

[0136] 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 very high, for example, it may reach over 600 degrees Celsius. 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 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 inside the heat exchanger 34, thereby heating the cleaning fluid, generating steam, and supplying the steam to the cleaning head 300. In this way, the temperature of the generated steam can be easily controlled within a safe range, thereby reducing safety risks, preventing damage to the items to be cleaned, and ensuring personal safety.

[0137] 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. Specifically, 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 embodiment is relatively flexible.

[0138] In embodiments not shown in this application, the auxiliary heating unit 3 and the electric heater 22 can also be connected in series. Specifically, when the auxiliary heating unit 3 is as follows... Figure 14 When only the auxiliary heater 31 is shown, 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 is as shown... Figure 15 When the system includes an auxiliary heater 31, a first water pump 32, a water tank 33, and a 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, allowing the cleaning fluid to pass sequentially through the electric heater 22 and the auxiliary heating unit 3, or sequentially through the auxiliary heating unit 3 and the electric heater 22, for dual heating to generate steam; alternatively, the control unit 5 can control only one of the electric heater 22 and the auxiliary heating unit 3 to operate. Clearly, 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 steam temperature regulation and also to the compact arrangement of the parts of the steam cleaner other than the auxiliary heating unit 3.

[0139] In one embodiment, the auxiliary heating unit 3 is used to provide hot air to the liquid spraying unit 21.

[0140] 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 out the hot air around the auxiliary heater 31 to form hot air, thereby heating the incoming cleaning fluid.

[0141] In other embodiments, the auxiliary heating unit 3 may also be a thermal energy storage device, including a shell, a heat charging unit, a heat storage material and a heat release unit, wherein the heat charging unit includes a heat charging module and the heat charging module includes a heat charging pipe.

[0142] In some embodiments, the energy source of the thermal energy storage device can 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.

[0143] In some embodiments, the energy source for the thermal energy storage device can be electrical energy converted from clean energy. For example, the thermal 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.

[0144] In some embodiments, the auxiliary heating unit 3 can also be used to provide steam, hot water, or hot air to the nozzle 310. Taking the auxiliary heating unit 3 as an example of providing steam to the nozzle 310, the steam pipeline for providing steam to the nozzle 310 can be shared with the original steam pipeline for providing steam to the spraying unit 21. Alternatively, a new steam branch can be added and connected to the original steam pipeline, and steam can be sprayed onto the surface to be cleaned through the nozzle 310. Of course, a new branch can also be opened within or in the nozzle 310 to output the steam, hot water, or hot air output by the auxiliary heating unit 3.

[0145] Understandably, in some embodiments, the auxiliary heating unit 3 may not be provided. The cleaning liquid can be heated by the electric heater 22 to generate steam, which can then provide steam to the spraying unit 21.

[0146] In actual setup, the structure of the cleaning head 300 is not limited.

[0147] In one embodiment, such as Figure 13 As shown, the cleaning head 300 may have a nozzle 310 and a suction port 12 (i.e., a negative pressure port 320) arranged circumferentially around the outer side of the nozzle 310, which is beneficial to improving the cleaning effect and cleaning efficiency.

[0148] In actual setup, the structure of the spray unit 21 is not limited.

[0149] In one embodiment, such as Figure 14 As shown, the cleaning source supply unit, also known as the spraying unit 21, may include an interconnected storage tank 211 and a second water pump 212. Specifically, the storage tank 211 can be used to store cleaning fluid, such as water. The outlet of the storage tank 211 can be connected to the inlet of the second water pump 212 via a pipe. The outlet of the second water pump 212 can be connected to the inlet of the electric heater 22, and the outlet of the electric heater 22 can be connected to the nozzle 310 of the cleaning head 300. The second water pump 212 can be an electromagnetic pump, capable of reliably and stably supplying cleaning fluid to the electric heater 22. The second water pump 212 can be connected to the control unit 5, which can control the start and stop of the steam generation unit 2 by controlling the start and stop of the second water pump 212. Thus, the spraying unit 21 has a simple structure and can efficiently provide cleaning fluid. Combined with the electric heater 22, under the control of the control unit 5, it can greatly improve the steam generation efficiency of the entire steam generation unit 2, which is beneficial for improving the cleaning effect and efficiency.

[0150] In actual installation, the structural form of sewage collection unit 4 is not limited.

[0151] In one embodiment, such as Figure 14 As shown, the wastewater collection unit 4 may include a wastewater tank 41 and a suction motor 42 connected to each other. Specifically, the inlet of the wastewater tank 41 can be connected to the suction port 12 of the cleaning head 300, and the inlet of the suction motor 42 can be connected to the outlet of the wastewater tank 41. The suction motor 42 can be connected to a control unit 5, which 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 helps to further improve the cleaning effect and efficiency.

[0152] In the embodiments provided in this application, the steam cleaner may also be equipped with a main unit 100, such as... Figure 11 As shown, the main unit 100 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 steam cleaner, making the structure more compact and the operation more convenient.

[0153] In specific configurations, the auxiliary heating unit 3 can be fully integrated into the main unit 100, or it can be connected to the main unit 100 as an external accessory. In the embodiments provided in this application, please refer to... Figure 12Understanding that the liquid storage tank 211, the second water pump 212, and the electric heater 22 of the steam generation unit 2 can be integrated into the main unit 100, and the auxiliary heating unit 3 can be connected to the main unit 100 as an external accessory. Specifically, the housing 61 of the main unit 100 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 the steam outlet of the auxiliary heating unit 3 are... Figure 14 In the embodiment shown, the pipe connecting the liquid inlet and gas outlet of the auxiliary heater 31 is shown. Figure 15 In the embodiment shown, the pipes connecting the refrigerant inlet and refrigerant outlet of the heat exchanger 34 can pass through the first heat source interface 62 and the second heat source interface 63 respectively, enter the housing 61, and connect to the two ends of the electric heater 22 respectively, so as to realize the parallel connection of the auxiliary heating unit 3 and the electric heater 22.

[0154] like Figure 11 and Figure 12 As shown, the bottom of the main unit 100 can also be equipped with casters 64, which makes the steam cleaner easy to move and improves the convenience of operation.

[0155] In the embodiments provided in this application, such as Figure 11 and Figure 12 As shown, the steam cleaner also includes a handle 200; the cleaning head 300 is connected to the steam generation unit 2 and the wastewater collection unit 4 via the handle 200. Thus, the position and orientation of the cleaning head 300 can be conveniently adjusted by holding the handle 200, which helps improve the cleaning effect and efficiency.

[0156] In the embodiments of this application, please refer to Figure 14 and Figure 15 It is understood that the steam generating unit 2 may also include a temperature sensor 23; the temperature sensor 23 can be connected to the control unit 5, and can be used to measure the temperature information 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 300 and the steam temperature information, so as to control the temperature of the steam sprayed by the spraying unit 21. In this way, automatic and efficient control of steam temperature can be achieved, which is beneficial to improving cleaning efficiency.

[0157] In the embodiments of this application, such as Figure 16 As shown, the handle 200 may also be provided with a negative pressure channel 72 (it can be seen that the negative pressure channel 72 is the first dirt channel 220 of the aforementioned embodiment) and a steam pipe channel 73. A steam delivery pipe 74 (the steam delivery pipe 74 is also the first cleaning channel 210 of the aforementioned embodiment) may be provided in the steam pipe channel 73. When the cleaning head 300 and the handle 200 are connected, the nozzle 310 of the cleaning head 300 can communicate with the steam delivery pipe 74, and the suction port 12 can communicate with the negative pressure channel 72. Furthermore, as... Figure 11 and Figure 12 As shown, the steam cleaner can also be equipped with a connecting pipe 9. The handle 200 can be connected to the main unit 100 through the connecting pipe 9. Specifically, the negative pressure channel 72 of the handle 200 can be connected to the wastewater tank 41 through the connecting pipe 9. The steam delivery pipe 74 can 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 can be a flexible hose, which makes it convenient to operate the handle 200 to adjust the position and posture of the cleaning head 300.

[0158] 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.

[0159] In the embodiments provided in this application, the steam cleaner further includes, for example, Figure 11 and Figure 12 The self-cleaning unit 8 shown; as Figure 14 and Figure 15 As shown, 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 300, and the control unit 5 is used to control the start and stop of the self-cleaning unit 8.

[0160] It is understandable that the cleaning head 300 sprays steam to clean the surface to be cleaned, generating dirt or wastewater 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 300, requiring frequent cleaning. Compared to the aforementioned utility model patent with authorization announcement number CN217429883U, which lacks an automatic cleaning head function and requires frequent manual cleaning when the cleaning head is contaminated, resulting in a time-consuming, labor-intensive, and poor user experience, the steam cleaner provided in the above embodiment of this application, equipped with a self-cleaning unit 8, can automatically clean the cleaning head 300 under the control of the control unit 5, improving self-cleaning efficiency, saving manpower, and enhancing the user experience.

[0161] The structure of the self-cleaning unit 8 is not limited in the specific configuration.

[0162] In one embodiment, such as Figure 11 and Figure 14 , Figure 15 As shown, 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 300 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 generating unit 2 according to the state of the sensor switch 82.

[0163] Thus, during use, after the cleaning head 300 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 generation unit 2 to start, generating steam that is ejected through the nozzle 310 of the cleaning head 300. Since a cleaning chamber can be formed inside the self-cleaning box 81, the steam can clean the cleaning head 300 within this chamber. This process only requires inserting the cleaning head 300 into the self-cleaning box 81, making operation convenient and quick. It enables rapid self-cleaning of the steam cleaner with high cleaning efficiency, further enhancing the user experience.

[0164] As can be seen, since the cleaning head 300 is connected to the steam generating unit 2 via the handle 200, it is clear that when the cleaning head 300 is inserted into the self-cleaning box 81 to achieve self-cleaning of the cleaning head 300, the walls of the dirt collection pipe in the handle 200 and the main unit 100 can also be cleaned, thus achieving self-cleaning of the cleaning head and the dirt collection pipe.

[0165] 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.

[0166] In the embodiments provided in this application, please refer to Figure 11 , Figure 12 , Figure 14 and Figure 15 It is understood that 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 steam cleaner, which may include a cleaning mode and a drying mode, which is also 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 achieved, making operation convenient and quick, and providing a better user experience.

[0167] In actual implementation, the specific structural form of the control component 52 is not limited. In one embodiment, the control component 52 may include, for example: Figure 11 The diagram shows a first control unit 521 and a second control unit 522. The first control unit 521 can be used to control the steam cleaner to enter or exit the cleaning mode, and the second control unit 522 can be used to control the steam cleaner to enter or exit the drying mode. In this way, dedicated control units can be set up for commonly used cleaning and drying functions, making operation more convenient and faster, and further improving the user experience.

[0168] 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 steam cleaner, 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 steam cleaner 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 this knob will allow the steam cleaner to enter the cleaning mode, enter the drying mode, and turn off the steam cleaner.

[0169] Furthermore, the control component 52 can be located on the handle 200 or on the housing 61 of the main unit 100; there is no specific limitation. In the embodiments of this application, such as Figure 11 As shown, the control component 52 is located on the handle 200. When the user holds the handle 200 to control the cleaning head 300 to work, he / she can conveniently operate the control component 52 on the handle 200 to switch the corresponding working mode and start / stop.

[0170] In the embodiments provided in this application, such as Figure 14 and Figure 15 As shown, a first level gauge 213 can be installed in the storage tank 211 of the steam generation unit 2, and a second level gauge 43 can be installed in the sewage tank 41 of the sewage collection unit 4. The first level gauge 213 and the second level gauge 43 can be connected to the controller 51. The controller 51 can control the operation of the second water pump 212 according to the liquid level of the storage tank 211 measured by the first level gauge 213, and can 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.

[0171] In this embodiment, the control unit 5 may further include a voice alarm unit 53; the voice alarm unit 53 may be connected to the controller 51. The control unit 5 may control the voice alarm unit 53 to issue a water shortage alarm when the water level in the storage tank 211 is lower than the first water level threshold, and may control the voice alarm unit 53 to issue a water full alarm when the water level in the sewage tank 41 is higher than the second water level threshold, so as to remind the user to replenish the water in the storage tank 211 and drain the sewage tank 41 in a timely manner to ensure the stable operation of the steam cleaning work.

[0172] In the embodiments provided in this application, the electric heater 22 of the steam generation unit 2 may also be equipped with a temperature protection switch to prevent safety accidents caused by excessive temperature.

[0173] exist Figure 14In the illustrated embodiment, the outlet of the electric heater 22 in the steam generation unit 2 can be connected to the nozzle 310 of the cleaning head 300 via the steam delivery pipe 74. A first control valve 24 can be installed on the pipe connecting the second water pump 212 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 212 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 212.

[0174] exist Figure 15 In the illustrated embodiment, and Figure 14 The difference in the embodiment shown is that in the auxiliary heating unit 3, the refrigerant inlet of the heat exchanger 34 can be connected to the outlet of the second water pump 212 through a pipe, and the refrigerant outlet of the heat exchanger 34 can be connected to the steam transmission pipe 74 through a pipe 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 212.

[0175] Both the first control valve 24 and the second control valve 35 can be flow proportional valves. The flow rate of water entering the electric heater 22 can be controlled by controlling the flow rate of the first control valve 24, or the flow rate of water 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 pipeline 74 and controlling the intensity of steam cleaning.

[0176] 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.

[0177] The steam cleaner provided in the above embodiments of this application can use clean energy to provide the heat required for steam generation, which can reduce the consumption of electricity and has a low cost. It can be widely used for cleaning objects such as tableware, fabrics, glass, vehicles, clothing, kitchens and floors, and has a wide range of applications.

[0178] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
