Description

[0001] This application is a divisional application of the invention application entitled "Cleaning Equipment and Steam Components", with parent application number "202211106187.4" and parent application date of September 10, 2022. Technical Field

[0002] This disclosure relates to the field of cleaning technology, and in particular to a cleaning device; this disclosure also relates to a steam assembly that should be applicable to the aforementioned cleaning device. Background Technology

[0003] With the development of social productivity, people's living standards have also improved. With their material needs met, people have begun to use various tools to reduce labor and improve their quality of life, leading to the emergence of household cleaning equipment.

[0004] One existing type of floor scrubber features a steam cleaning function. The steam unit sprays high-temperature steam onto the floor through multiple nozzles, making it easier to clean stains. To meet the need for multiple steam modes in the cleaning machine market, such as burst spray and multi-hole uniform spray modes, the burst spray and uniform spray channels must not interfere with each other. This results in the spray plates occupying a relatively large volume and having a complex structure, which is not conducive to cost control. Summary of the Invention

At least part of the inner channel of the first plate and the inner channel of the third plate are located on the same layer.

[0007] In one embodiment of this disclosure, the steam assembly further includes a first channel for supplying steam to the first nozzle and a second channel for supplying steam to the second nozzle; the steam generator supplies steam to the first channel and the second channel; the first plate inner channel is connected to the first channel through a first air inlet, and the second plate inner channel is connected to the second channel through a second air inlet.

[0008] In one embodiment of this disclosure, the floor brush assembly is provided with a roller brush and a roller brush cover detachably connected above the roller brush, and the steam spray plate, the first channel and the second channel are provided on the roller brush cover.

[0009] In one embodiment of this disclosure, the floor brush assembly is provided with a first steam outlet and a second steam outlet; when the roller brush cover is installed in place, the first steam outlet is connected to the first channel, and the second steam outlet is connected to the second channel.

[0010] In one embodiment of this disclosure, the line connecting the first steam outlet and the first air inlet is perpendicular to the axis of the roller brush.

[0011] In one embodiment of this disclosure, the second steam outlet is located between the first steam outlet and one of the second air inlets.

[0012] In one embodiment of this disclosure, the two second nozzles are located at both ends of the channel within the third plate.

[0013] In one embodiment of this disclosure, the second inner channel and the third inner channel are arranged in parallel.

[0014] In one embodiment of this disclosure, the steam spray plate is provided with two second air inlets, four second spray holes, two second plate inner channels, and two third plate inner channels.

[0015] In one embodiment of this disclosure, the first plate inner channel includes three ends, which are respectively connected to two first nozzles and one first air inlet.

[0016] In one embodiment of this disclosure, the first plate inner channel includes a main channel connecting the first air inlet and a diversion channel connecting the two first nozzles, wherein the main channel is connected in the middle of the diversion channel; the diversion channel and the third plate inner channel are located on the same layer.

[0017] In one embodiment of this disclosure, the first nozzle and the second nozzle are arranged on the same straight line.

[0018] According to a second aspect of this disclosure, a steam assembly is also provided, including a steam generator and a steam spray plate, wherein one side of the steam spray plate is provided with at least two first spray holes and a plurality of second spray holes for spraying steam onto a working face, and the other side is provided with a first air inlet and at least two second air inlets located on both sides of the first air inlet.

At least part of the inner channel of the first plate and the inner channel of the third plate are located on the same layer.

[0019] One beneficial effect of this disclosure is that when the steam assembly ejects steam only through the first nozzle, it operates in burst spray mode, where the steam pressure is higher and the cleaning force on the working surface is stronger. When the steam assembly ejects steam simultaneously through the first and second nozzles, it operates in uniform mode, where more nozzles are open at the same time, resulting in lower steam pressure but a larger steam coverage area and thus a wider cleaning range. Since the first nozzle participates in steam injection in both burst spray and uniform modes, the overall number of nozzles can be reduced, which helps to reduce the size of the steam spray plate, lower costs, and facilitates the miniaturization of cleaning equipment.

[0020] Other features and advantages of this disclosure will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings. Attached Figure Description

[0030] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0031] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0032] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0033] This disclosure provides a cleaning device including a floor brush assembly and a steam assembly for cleaning a work surface. The cleaning device can be a handheld floor scrubber with steam cleaning function, a self-propelled cleaning robot, etc. The steam assembly includes a steam spray plate disposed on the floor brush assembly. The steam spray plate has at least one first nozzle and multiple second nozzles for spraying steam onto the work surface. It also includes a first channel for supplying steam to the first nozzles and a second channel for supplying steam to the second nozzles. The steam assembly is configured to supply steam to the first nozzles via the first channel, or to supply steam to both the first and second nozzles simultaneously via the first and second channels.

[0034] The first and second nozzles on the steam spray plate are used to spray steam onto the working surface for sterilization and cleaning. When the steam assembly only sprays steam through the first nozzle, it operates in burst spray mode, where the steam pressure is high and the cleaning force is stronger. When the steam assembly sprays steam through both the first and second nozzles simultaneously, it operates in uniform mode, with more nozzles open at the same time. While the steam pressure is lower, the steam coverage area is larger, resulting in a wider cleaning range. Compared to existing technologies, the first nozzle of the cleaning equipment in this disclosure participates in steam spraying in both burst spray and uniform modes, reducing the overall number of nozzles. This allows for a smaller steam spray plate, lower costs, and facilitates the miniaturization of the cleaning equipment.

[0035] The technical solution disclosed herein will be described in detail below with reference to its specific structure.

[0036] In one embodiment of this disclosure, reference is made to Figure 1 , Figure 2 This disclosure provides a cleaning device, including a floor brush assembly 1 and a steam assembly 2 disposed on the floor brush assembly 1. The floor brush assembly 1 can move on the working surface by means of rollers, auxiliary wheels, etc., and clean the working surface. The steam assembly 2 is used to spray high-temperature steam onto the working surface for sterilization and cleaning, so that dirt on the working surface can be easily cleaned.

[0037] The steam assembly 2 includes a steam spray plate 20, a first channel 21, and a second channel 22 disposed on the floor brush assembly 1. The steam spray plate 20 is provided with a first nozzle 201 and a second nozzle 202 for spraying steam onto the working surface. The first channel 21 supplies steam to the first nozzle 201, and the second channel 22 supplies steam to the second nozzle 202. Specifically, the floor brush assembly 1 is also provided with a steam generator 23, which is connected to the first channel 21 and the second channel 22. The steam generated by the steam generator 23 can be supplied to the first nozzle 201 through the first channel 21 and to the second nozzle 202 through the second channel 22.

[0038] At least one first nozzle 201 is provided, and at least two second nozzles 202 are provided. The first nozzle 201 and the second nozzle 202 can be nozzles with identical structure and size, or they can be different nozzles. For example, the first nozzle 201 may employ a nozzle structure with a relatively faster steam ejection velocity, while the second nozzle 202 may employ a nozzle structure with a relatively slower steam ejection velocity. At least one first channel 21 is provided, and each first channel 21 may be connected to one or more first nozzles 201. At least one second channel 22 is provided, and each second channel 22 may be connected to one or more second nozzles 202.

[0039] The steam spray plate 20 can spray steam onto the working face through all orifices or only some orifices in different working modes. Specifically, the steam assembly 2 has a burst spray mode and a uniform spray mode; in the burst spray mode, the steam spray plate 20 sprays steam only through the first orifice 201; in the uniform spray mode, the steam spray plate 20 sprays steam through all the first orifices 201 and the second orifice 202.

[0040] In some embodiments of this disclosure, reference is made to Figure 2 , Figure 3 The steam assembly 2 also includes a control valve 24, which is used to control the opening or closing of the second channel 22. That is, the first channel 21 is directly connected to the steam generator 23, and the second channel 22 is connected to the steam generator 23 through the control valve 24.

[0041] In burst spray mode, control valve 24 is closed, steam generator 23 only supplies steam to first channel 21, first nozzle 201 sprays steam onto the working surface, and the sprayed steam pressure is high. The steam spray volume of each first nozzle 201 is large, the cleaning range is relatively concentrated, and the cleaning power is stronger. It is suitable for situations where it is necessary to focus on cleaning dirt on the working surface.

[0042] In uniform mode, control valve 24 is opened, and steam generator 23 supplies steam to first channel 21 and second channel 22. First nozzle 201 and second nozzle 202 simultaneously spray steam onto the working surface. The positions of the first nozzle 201 and the second nozzle 202 are relatively dispersed and there are many of them. The steam pressure is relatively low and the amount of steam sprayed from each nozzle is relatively small, but the cleaning range is larger and the utilization efficiency of the first nozzle 201 is improved. This helps to simplify the structure of the steam spray plate 20 and reduce costs.

[0043] In some embodiments of this disclosure, reference is made to Figure 2 The first nozzle 201 and the second nozzle 202 on the steam spray plate 20 are arranged on the same straight line and are distributed at intervals on the steam spray plate 20, with a certain distance between adjacent nozzles. This helps to reduce the volume of the steam spray plate 20, save space, and make the sprayed steam more uniform. In detail, the steam spray plate 20 is designed as an elongated structure, and the first nozzle 201 and the second nozzle 202 can be distributed along the extension direction of the steam spray plate 20, resulting in a compact structure.

[0044] In one embodiment of this disclosure, reference is made to Figure 2 The first nozzle 201 is located in the middle area of ​​the steam spray plate 20, and the second nozzle 202 is located at opposite ends of the steam spray plate 20, meaning the first nozzle 201 is located between the second nozzles 202. In burst spray mode, the first nozzle 201 can spray steam towards the middle position, which is beneficial for moving the cleaning equipment so that the first nozzle 201 is aligned with the areas on the work surface that need to be cleaned. Positioning the second nozzles 202 at both ends of the steam spray plate 20 facilitates a more even distribution of steam in uniform spray mode.

[0045] In one embodiment of this disclosure, reference is made to Figure 2 The steam spray plate 20 includes a first plate inner channel 203 communicating with at least two first spray holes 201. The first plate inner channel 203 is connected to a first channel 21 via a first air inlet 205. The distance from the first air inlet 205 to the two first spray holes 201 is equal. And / or, the steam spray plate 20 includes a second plate inner channel 204 communicating with at least two second spray holes 202. The second plate inner channel 204 is connected to a second channel 22 via a second air inlet 206. The distance from the second air inlet 206 to the at least two second spray holes 202 is equal.

[0046] In one specific implementation, reference is made to... Figure 2The first nozzle 201 and the second nozzle 202 are located on the same side of the steam spray plate 20, and the first air inlet 205 and the second air inlet 206 are located on the opposite side of the steam spray plate 20. At least two second air inlets 206 are provided, and each of the at least two second air inlets 206 is located on either side of the first air inlet 205. The first air inlet 205 is located between the first nozzles 201, and one of the second air inlets 206 is located between the second nozzle 202 and the first air inlet 205 on the same side. This disclosure places the first air inlet 205 between the two first nozzles 201, thereby shortening the conveying distance of the inner channel 203 of the first plate and making the path length more balanced, ensuring that each first nozzle 201 receives a stable and uniform steam supply; at the same time, the second air inlet 206 is located between the second nozzle 202 on the same side and the first air inlet 205, thereby avoiding the problem of the steam conveying path being too long due to the second air inlet 206 being too close to the end, and ensuring that the layout of the inner channel 204 of the second plate does not conflict with that of the inner channel 203 of the first plate.

[0047] The first plate inner channel 203 connects two first nozzles 201 and one first air inlet 205. The first plate inner channel 203 has three ends, each connected to one of the two first nozzles 201 and one of the first air inlets 205. Furthermore, the first plate inner channel 203 includes a main channel connecting the first air inlet 205 and a branch channel connecting the two first nozzles 201. The branch channel is a straight channel, and the main channel is connected in the middle of the branch channel, thus ensuring that the distance from the first air inlet 205 to the two first nozzles 201 is equal. The second plate inner channel 204 connects two second nozzles 202 and one second air inlet 206. The two second nozzles 202 are connected to opposite ends of the first plate inner channel 203, and the second air inlet 206 is connected in the middle of the second plate inner channel 204, thus ensuring that the distance from the second air inlet 206 to at least two second nozzles 202 is equal.

[0048] refer to Figure 2 The second air inlet 206 guides the steam to both ends through the second inner plate channel 204, then splits it through the third inner plate channel, and connects to the second nozzle 202. Specifically, the second inner plate channel 204 and the third inner plate channel are arranged parallel to each other, and their extension directions can be consistent with the extension direction of the steam spray plate 20. Steam from the second air inlet 206 can flow away from the central area through the second inner plate channel 204, and when it flows through the connection point between the second inner plate channel 204 and the third inner plate channel, it flows into the third inner plate channel under the action of gravity, and continues to flow towards the second nozzle 202 within the third inner plate channel. The two second nozzles 202 are located at the two ends of the third inner plate channel, respectively. Since the second inner plate channel 204 is connected to the middle of the third inner plate channel, the distance from the second air inlet 206 to at least two second nozzles 202 is equal, improving the uniformity of the steam.

[0049] like Figure 2 As shown, at least part of the first plate inner channel 203 and the third plate inner channel are located on the same layer. Specifically, the diversion channel of the first plate inner channel 203 and the third plate inner channel are located on the same layer and extend in the same straight direction. It can be understood that the diversion channel is used to connect to the first nozzle 201, and the third plate inner channel is used to connect to the second nozzle 202. As mentioned above, the first nozzle 201 and the second nozzle 202 are arranged on the same straight line. In this disclosure, the diversion channel and the third plate inner channel are arranged flush, which can further optimize the internal layout of the steam spray plate 20 and reduce the volume of the steam spray plate 20.

[0050] Furthermore, the steam spray plate 20 includes a first inner plate channel 203 and two second inner plate channels 204. The first inner plate channel 203 is located in the middle region of the steam spray plate 20, and the two second inner plate channels 204 are located at both ends of the steam spray plate 20. The steam spray plate 20 is provided with a total of four second spray holes 202, two first spray holes 201, two second inner plate channels 204, and two third inner plate channels.

[0051] In one embodiment of this disclosure, reference is made to Figure 1 The direction of travel of the floor brush assembly 1 is defined as forward, and the steam spray plate 20 is set on the front side of the floor brush assembly 1. During operation, the floor brush assembly 1 moves forward, and the steam spray plate 20 first sprays steam onto the working surface in front of the floor brush assembly 1 to perform preliminary cleaning on the working surface. As the floor brush assembly 1 moves forward, it further cleans the area that has been sprayed with steam, thereby thoroughly cleaning the working surface.

[0052] In one embodiment of this disclosure, reference is made to Figure 1 The floor brush assembly 1 is equipped with a roller brush 11, which can rotate on the working surface under the action of a drive device to clean the working surface. The rotation axis of the roller brush 11 is aligned with the axis of the traveling wheel on the floor brush assembly 1. The floor brush assembly 1 also includes a detachably connected roller brush cover 12, which is fastened above the roller brush 11 to protect it. The roller brush cover 12 can be configured as an arc-shaped structure adapted to the shape of the roller brush 11. Specifically, the roller brush cover 12 extends forward from the upper rear side of the roller brush 11 to the top of the roller brush 11, and then extends to the front side of the roller brush 11.

[0053] In one specific embodiment of this disclosure, the steam spray plate 20 extends along the axial direction of the roller brush 11, and the first spray hole 201 and the second spray hole 202 are distributed along the extension direction of the steam spray plate 20 to increase the coverage area of ​​the steam as the floor brush assembly 1 moves forward. In one embodiment of this disclosure, reference is made to Figure 1 , Figure 4The steam generator 23 and control valve 24 are located behind the roller brush 11 and within the inner cavity of the floor brush assembly 1. The floor brush assembly 1 has a first steam outlet 25 directly connected to the steam generator 23 and a second steam outlet 26 connected to the control valve 24. When the roller brush cover 12 is installed in place, the first steam outlet 25 is connected to and aligned with the first channel 21, and the second steam outlet 26 is connected to and aligned with the second channel 22. Figure 4 As shown, the second steam outlet 26 is located between the first steam outlet 25 and one of the second air inlets 206. This arrangement allows the first steam outlet 25 and the second steam outlet 26 to be more concentrated in the central area of ​​the brush assembly 1, which helps to shorten the length of the first channel 21 and the second channel 22, making the structural layout more compact. The line connecting the first steam outlet 25 and the first air inlet 205 is perpendicular to the axis of the roller brush 11. In this embodiment, as shown... Figure 3 As shown, the first channel 21 extends along a straight line. The first channel 21 is the line connecting the first steam outlet 25 and the first air inlet 205. The first channel 21 is perpendicular to the axis of the roller brush 11.

[0054] In one embodiment of this disclosure, reference is made to Figure 1 The floor brush assembly 1 also includes safety valves 3 for closing the first steam outlet 25 and the second steam outlet 26 respectively, that is, safety valves 3 are provided on both the first steam outlet 25 and the second steam outlet 26. The safety valves 3 are configured to open the first steam outlet 25 when the first channel 21 is connected to the first steam outlet 25, and to open the second steam outlet 26 when the second channel 22 is connected to the second steam outlet 26.

[0055] In detail, the safety valve 3 includes a valve chamber 30 and a valve core 31 disposed in the valve chamber 30 via an elastic device 32. The valve core 31 closes the valve chamber 30 under the action of the elastic device 32, that is, closes the first steam outlet 25 and the second steam outlet 26. The first channel 21 is connected to the first steam outlet 25 via a connector, and the second channel 22 is connected to the second steam outlet 26 via a connector. Both the connectors of the first channel 21 and the second channel 22 are provided with a pin structure. When connected to the first steam outlet 25 and the second steam outlet 26, the pin structure cooperates with the safety valve 3 and overcomes the force of the elastic device 32 to push the valve core 31 to move, thereby opening the valve chamber 30, opening the first steam outlet 25 and the second steam outlet 26, and supplying steam to the first channel 21 and the second channel 22.

[0056] When the user manually disassembles the roller brush cover 12, the pin structure of the first channel 21 and the pin structure of the second channel 22 disengage from the corresponding safety valve 3. Under the action of the elastic device 32, the valve core 31 of the safety valve 3 is driven to close the valve chamber 30, preventing steam from being discharged from the first steam outlet 25 and the second steam outlet 26, so as to avoid scalding people with high temperature steam and improve the safety of the cleaning equipment.

[0057] In one embodiment of this disclosure, reference is made to Figure 5 , Figure 6 The floor brush assembly 1 is also equipped with a light assembly 4, which is configured to emit light in different light-emitting modes when the first nozzle 201 emits steam and when the first nozzle 201 and the second nozzle 202 emit steam simultaneously.

[0058] In detail, the lighting assembly 4 can be mounted on the steam spray plate 20 or the roller brush cover 12. The lighting assembly 4 includes an outer frame and multiple lamp tubes mounted on the outer frame. The position and number of lamp tubes can be set to correspond to the first spray hole 201 and the second spray hole 202. Each first spray hole 201 and second spray hole 202 has a corresponding lamp tube. The control lines and power lines of the lamp tubes can be set to be the same as the air path layout of the corresponding spray hole, referring to the layout of the first spray hole 201, the second spray hole 202, and the inner channels 203 and 204 of the first plate.

[0059] When steam is emitted from the first nozzle 201 and the second nozzle 202, the corresponding lamp illuminates; otherwise, the corresponding lamp turns off. The illumination modes include a burst emission mode and a uniform illumination mode. In the burst emission mode, steam is emitted from the first nozzle 201, and the lamp corresponding to the first nozzle 201 illuminates; in the uniform illumination mode, steam is emitted from the first nozzle 201 and the second nozzle 202, and all lamps corresponding to the first nozzle 201 and the second nozzle 202 illuminate. When the steam spray plate 20 switches between the burst emission mode and the uniform illumination mode, the lighting component 4 can switch instantaneously or gradually between the two illumination modes.

[0060] This disclosure also provides a steam assembly that can be applied to cleaning equipment such as steam floor scrubbers, steam cleaning robots, and garment steamers. The steam assembly includes a steam spray plate 20, which has at least one first nozzle 201 and multiple second nozzles 202 for spraying steam onto a work surface. It also includes a first channel 21 for supplying steam to the first nozzles 201 and a second channel 22 for supplying steam to the second nozzles 202. The steam assembly 2 is configured to supply steam to the first nozzles 201 through the first channel 21, or to supply steam to both the first nozzles 201 and the second nozzles 202 simultaneously through the first channel 21 and the second channel 22. The specific structure and principle of the steam assembly of this disclosure can be found in the steam assemblies described above in the cleaning equipment, and will not be repeated here.

[0061] The technical solution adopted in this disclosure will be explained below with reference to specific application scenarios to aid understanding. The application scenario below uses a floor scrubbing machine as an example.

[0062] Application Scenario 1 During operation, the floor scrubber's brush assembly 1 moves forward, and the steam spray plate 20 first sprays steam onto the working surface in front of the brush assembly 1 for initial cleaning. The brush assembly 1 then moves forward to further clean the areas previously cleaned by the steam, thus thoroughly cleaning the working surface. The steam assembly has a uniform mode with a wider cleaning range and more even steam distribution, and a burst mode with a concentrated cleaning range and greater cleaning power. In uniform mode, the control valve 24 of the steam assembly 2 is open, and the steam generator 23 directly supplies steam to the first nozzle 201 through the first channel 21 and to the second nozzle 202 through the second channel 22. Because there are many nozzles spraying steam, the steam pressure from each nozzle is relatively low and relatively uniform. In burst mode, the control valve 24 is closed, and the steam generator 23 only supplies steam to the first nozzle 201 through the first channel 21. The steam pressure is higher, resulting in greater cleaning power on the working surface. The first nozzle 201 participates in steam injection in both burst spray mode and uniform spray mode, which can reduce the total number of nozzles, thus helping to reduce the volume of the steam spray plate and lower costs.
