However, the various components within the cleaning equipment used to output foam are usually set up independently, which often requires a large number of pipes to connect these components. This not only occupies a lot of installation space within the cleaning equipment but also makes assembly complex. Utility Model Content

[0021] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:
[0022] In use, one of the second and third connectors of the foam generating device disclosed herein can be used to connect to a liquid path, such as a pipeline for conveying a foaming agent, which may be a cleaning liquid, etc. The other of the second and third connectors can be used to connect to a gas path, such as a pipeline for conveying air.

Detailed Implementation
[0039] The technical solutions in the embodiments (or "implementations") of this disclosure will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0040] If this disclosure uses terms relating to directional indications or positional relationships (e.g., up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, terms such as "first" and "second" in this disclosure are used only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0041] With technological advancements and social progress, more and more families are using cleaning equipment such as fabric cleaning machines, carpet cleaning machines, and floor scrubbers to improve the efficiency and quality of household cleaning. Currently, there are numerous brands of cleaning equipment available for consumers to choose from. How to win consumer favor and enhance product competitiveness is an increasingly important issue for cleaning equipment manufacturers.
[0042] Taking floor scrubbers as an example, floor scrubbers are a common type of cleaning equipment. They can move across the floor and clean dirt using brushes. For instance, household floor scrubbers can be handheld and dragged by the user to clean dirty floors. Floors typically have varying degrees of dirt, including easily cleanable light dirt such as dust, hair, or sweat stains, as well as more stubborn dirt such as oil stains, limescale, or mold. To combat stubborn dirt, some floor scrubbers have a foam spraying function. The foam is usually formed by mixing cleaning fluid and air in the tubing and entering the foamer. The foam is then sprayed through nozzles to cover and dissolve stubborn stains.
[0043] However, the various components inside a floor scrubber that output foam are usually set up independently, which often requires a lot of piping to connect the components. This not only takes up a lot of installation space inside the floor scrubber, but also makes assembly complicated and inefficient.
[0044] Based on this, the present disclosure provides a foam generating device that simplifies the connection piping between the various components used to output foam, saves installation space, and improves assembly efficiency. Furthermore, the foam generating device provided by the present disclosure is applicable to cleaning equipment such as fabric cleaning machines, carpet cleaning machines, or floor scrubbers, and the present disclosure does not impose any limitations.
[0045] The foam generating apparatus 10 provided in this disclosure will now be described in conjunction with the accompanying drawings.
[0046] See Figure 1 and Figure 2 This disclosure provides a foam generating device 10, including a foaming assembly 11 and a connector 12 fixed to the foaming assembly 11. The foaming assembly 11 has a foaming cavity 112, an inlet 113 communicating with the foaming cavity 112, and an outlet 114 communicating with the foaming cavity 112. The connector 12 has at least three joints, including a first joint 121 that is sealed and communicates with the inlet 113, and a second joint 122 and a third joint 123 that are respectively communicated with the first joint 121.
[0047] It should be noted that one of the second connector 122 and the third connector 123 can be used to connect to a liquid path, such as a pipeline for conveying a foaming agent, which can be a cleaning liquid, etc. The other of the second connector 122 and the third connector 123 can be used to connect to a gas path, such as a pipeline for conveying air. The first connector 121 of the connector 12 can be used to connect to the inlet 113 of the foaming chamber 112. In this way, the connector 12 can directly introduce the foaming agent and gas into the foaming chamber 112 respectively, so that the foaming agent and air mix to form foam, which is then discharged from the foaming chamber 112 through the outlet 114, thereby using the foam to clean dirt.
[0048] Understandably, connector 12 can be a tee connector. Of course, if the foam generating device 10 requires other media to enter the foaming chamber 112 to participate in foaming, connector 12 can also be a four-way connector or a five-way connector, etc., and this disclosure does not impose any restrictions.
[0049] Thus, the foam generating device 10 provided in this disclosure integrates the foaming component 11 and the connector 12, enabling the foam generating device 10 to be directly connected to various media pipelines such as gas or liquid lines, thereby reducing the need for additional connecting pipelines between the various components that output foam. On the one hand, the foam generating device 10 simplifies pipeline layout, reduces maintenance difficulty, and saves assembly space, providing more layout space for other components. On the other hand, the foam generating device 10 reduces connection points, thereby reducing the risk of pipeline leakage and improving assembly reliability. Simultaneously, the integrated design of the foam generating device 10 reduces assembly complexity and improves assembly efficiency.
[0050] See Figure 1 and Figure 2 In one embodiment, the foaming assembly 11 includes a foaming shell 111 with a foaming cavity 112 and at least one foaming structure disposed within the foaming shell 111. The first connector 121 is fixed to the foaming shell 111 and is in sealed communication with the inlet portion 113.
[0051] It should be noted that after the first connector 121 of the connector 12 is directly connected to the foaming cavity 112 via the inlet 113, the first connector 121 can also be fixedly connected to the foaming shell 111 to achieve the integrated arrangement of the connector 12 and the foaming assembly 11. Simultaneously, it can seal the first connector 121 and the inlet 113 to prevent leakage at the connection. Understandably, after the first connector 121 and the inlet 113 are correspondingly connected, the first connector 121 and the foaming shell 111 can be fixed by welding, threaded connection, screw fixing, insertion, or sealing, etc., and this disclosure does not impose any limitations.
[0052] Thus, the second connector 122 and the third connector 123 of the connector 12 can be connected to the liquid path and the gas path respectively, so that the two fluid media, liquid and gas, are initially mixed and then introduced into the foaming chamber 112 from the inlet 113 through the first connector 121. Under the action of the foaming structure (not shown in the figure), the liquid and gas can be fully mixed in the foaming chamber 112 to form foam, and finally discharged from the outlet 114 of the foaming chamber 112, so as to act on the surface to be cleaned and clean the dirt.
[0053] Understandably, at least one foaming structure includes at least one of a filter screen, a stirring element, and a porous structure, and this disclosure is not limiting. Wherein, if the foaming structure is a filter screen or a porous structure, a liquid with a certain impact force and a gas with a certain impact force can mix rapidly after entering the foaming chamber 112, and under the action of the filter screen or porous structure, the liquid and gas can form foam during the mixing process. Furthermore, the filter screen can be removed and replaced from the outlet 114 of the foaming chamber 112 to avoid clogging after prolonged use, which would affect foam output. If the foaming structure is a stirring element, the stirring element can reciprocate within the foaming chamber 112 to fully stir the liquid and gas through vibration or rotation, thereby generating foam.
[0054] In this way, the foamed structure can provide a hybrid gas-liquid mixture, allowing for more thorough mixing. Of course, the foamed structure can also be designed to generate foam by utilizing the impact force of the gas and liquid themselves in the pipeline without providing a hybrid gas-liquid mixture; this disclosure does not impose any limitations.
[0055] See Figure 1 and Figure 2 In one embodiment, the foam shell 111 and the connector 12 are an integral structure. This improves the structural stability between the foam shell 111 and the connector 12, thereby enabling it to withstand the fluid pressure within the pipeline to mix and form foam, and preventing pipeline leakage. Furthermore, the foam shell 111 and the connector 12 can be integrally molded to reduce the complexity of the foam generating device 10 during manufacturing and assembly, thus saving assembly space and simplifying assembly, which helps reduce production costs. Understandably, the foam shell 111 and the connector 12 can be formed into an integral structure through injection molding, die casting, stamping, or 3D printing, etc., and this disclosure does not impose any limitations.
[0056] See Figure 1 and Figure 2 In one embodiment, the first connector 121 and the second connector 122 are coaxially arranged, and the third connector 123 is connected between the first connector 121 and the second connector 122.
[0057] It should be noted that the first connector 121 and the second connector 122 can be coaxially arranged along the length of the connector 12. The second connector 122 is used to connect the liquid path, so that the liquid can directly enter the foaming chamber 112 by means of the first connector 121 and the second connector 122 being coaxially arranged, thereby reducing the pressure loss of the liquid flow.
[0058] Understandably, the third connector 123 is used to connect the gas path. The third connector 123 can be arranged perpendicular to the axis of the first connector 121 and the second connector 122, so that the gas can be directly mixed with the liquid and carried into the foaming chamber 112 by the liquid flow, so as to mix and generate foam in the foaming chamber 112. Of course, the third connector 123 can also be arranged at an angle relative to the axis of the first connector 121 and the second connector 122. For example, the third connector 123 can be arranged at an acute angle with the second connector 122, so that the liquid and gas can flow towards the first connector 121 and be pre-mixed. This disclosure does not impose any limitations.
[0059] See Figure 1 and Figure 2 In one embodiment, to avoid liquid turbulence, the inner diameter of the second connector 122 is not smaller than the inner diameter of the third connector 123. Understandably, the second connector 122 is used to connect the liquid path, and the third connector 123 is used to connect the gas path. Thus, the gas path injects into the liquid path through the smaller inner diameter third connector 123, preventing excessive gas impact from causing liquid flow turbulence and preventing it from entering the foaming chamber 112.
[0060] join Figure 1 and Figure 2 In one embodiment, to facilitate fluid entry into the foaming chamber 112, the inner diameter of the first connector 121 is not less than the inner diameter of the second connector 122. Thus, the connection between the connector 12 and the foaming chamber 112 is relatively large. After the gas and liquid are initially mixed, the mixture can enter the foaming chamber 112 from the larger first connector 121 through the inlet 113, avoiding blockage at the inlet 113 of the foaming chamber 112.
[0061] See Figure 1 and Figure 2 In one embodiment, to facilitate the connection of the foam generating device 10 to the various pipelines, at least one of the second connector 122 and the third connector 123 is further provided with a connection guide 124.
[0062] It should be noted that, taking the second connector 122 with a connecting guide 124 as an example, if the second connector 122 is connected into the liquid circuit, the connecting guide 124 can be a conical structure disposed on the outer wall of the second connector 122. The outer diameter of the conical structure gradually decreases from the first connector 121 towards the second connector 122, so that the second connector 122 can be easily inserted into the liquid circuit connector, and the conical structure provides a seal to prevent leakage at the connection. Of course, if the second connector 122 is fitted onto the outside of the liquid circuit connector, the connecting guide 124 can be a conical structure disposed on the inner wall of the second connector 122. In this case, the inner diameter of the conical structure gradually increases from the first connector 121 towards the second connector 122, so that the second connector 122 can be fitted onto the outside of the liquid circuit connector, and the conical structure provides a seal. Correspondingly, the third connector 123 can also be provided with a connecting guide 124, which will not be elaborated upon in this disclosure.
[0063] In addition to the foam generating device 10 described above, this disclosure also provides a foam generating device 10 with a nozzle 13, which will be described below.
[0064] See Figures 3 to 5 In one embodiment, in order to enable foam to be ejected from the foaming chamber 112 to a designated location, the foam generating device 10 further includes a nozzle 13, which is fixed to the foaming assembly 11 and communicates with the outlet 114.
[0065] It should be noted that nozzle 13 can be used to directly spray foam onto dirt, providing targeted and / or quantitative foam output. The spray range and spray force of nozzle 13 can be adjusted according to user needs, and this disclosure does not impose any limitations. Thus, after the foaming agent and gas are introduced into the foaming chamber 112 via connector 12 to generate foam, the foam can be sprayed from nozzle 13 through outlet 114 to a designated location for targeted cleaning of dirt. At the same time, nozzle 13 enables uniform and stable foam output, thereby improving cleaning effect and efficiency.
[0066] Understandably, the nozzle 13 can be directly fixed to the foam housing 111 and connected to the outlet 114 to achieve integrated installation of the nozzle 13 and the foam assembly 11, reducing the need for additional connecting pipes between the nozzle 13 and the foam assembly 11, thereby simplifying the assembly structure and improving assembly efficiency. Furthermore, the nozzle 13 and the foam housing 111 can be fixed by welding, threaded connection, screw fixing, plugging, or sealing, etc., and this disclosure does not impose any limitations.
[0067] See Figures 3 to 5In one embodiment, the foaming assembly 11 includes a foaming shell 111 with a foaming cavity 112 and at least one foaming structure disposed within the foaming shell 111, wherein the foaming shell 111 is an integral structure with at least one of the nozzle 13 and the connector 12.
[0068] It should be noted that, taking the integrated structure of the foam shell 111 and the nozzle 13 as an example, this improves the structural stability between the foam shell 111 and the nozzle 13, thereby enabling it to withstand the foam ejection pressure and preventing leakage in the foam ejection pipeline. Furthermore, the integrated structure of the foam shell 111 and the nozzle 13 reduces the complexity of the foam generating device 10 during manufacturing and assembly, thus saving assembly space, simplifying assembly, and helping to reduce production costs. Understandably, the foam shell 111 and the nozzle 13 can be formed into an integrated structure through injection molding, die casting, stamping, or 3D printing, and this disclosure does not impose any limitations.
[0069] Of course, in other embodiments, the foaming shell 111, nozzle 13, and connector 12 can also be an integrated structure. In this way, the foam generating device 10 compactly combines the foaming component 11, connector 12, and nozzle 13, significantly reducing the space occupied inside the cleaning equipment 1, achieving miniaturization and weight reduction of the cleaning equipment 1, and improving its portability and flexibility. Simultaneously, this arrangement provides more layout space for other key components within the cleaning equipment 1. Furthermore, this arrangement reduces the need for additional connecting pipes between the three components, simplifying pipe layout, reducing the risk of pipe breakage, extending the service life of the foam generating device 10, and reducing maintenance costs and downtime of the cleaning equipment 1. Moreover, this integrated design simplifies the manufacturing and assembly process of the foam generating device 10, reduces assembly difficulty, and improves assembly efficiency, contributing to improved production efficiency and quality control of the cleaning equipment 1. Furthermore, the integrated design of the foam generating device 10 also improves its structural strength, effectively reduces leakage risk, and enhances the overall performance and reliability of the foam generating device 10. Furthermore, this integrated design makes the overall structure of the foam generating device 10 compact, which helps to reduce pressure loss and energy consumption during fluid transmission and further improves foam generation efficiency.
[0070] Understandably, the integrated design of the foam generating device 10 can be formed into an integrated structure through injection molding, die casting, stamping or 3D printing, etc., and this disclosure does not impose any restrictions.
[0071] See Figure 6In other embodiments, this disclosure also provides a foam generating device 10, including a foaming assembly 11 and a nozzle 13 fixed to the foaming assembly 11. The foaming assembly 11 is provided with a foaming cavity 112, an inlet portion 113 communicating with the foaming cavity 112, and an outlet portion 114 communicating with the foaming cavity 112, and the nozzle 13 is communicating with the outlet portion 114.
[0072] It should be noted that the foaming component 11 is directly connected to the nozzle 13. The inlet 113 of the foam component is a free end, which can be used to assemble the connector 12 or directly connect to the foaming pipeline. This disclosure does not impose any limitations.
[0073] Understandably, the foaming assembly 11 includes a foaming shell 111 with a foaming cavity 112 and at least one foaming structure disposed within the foaming shell 111. The foaming shell 111 and the nozzle 13 are integrally formed. This integrated arrangement of the foaming shell 111 and the nozzle 13 also seals the connection between the nozzle 13 and the outlet 114, preventing leakage at the connection. Understandably, the at least one foaming structure includes at least one of a filter screen, a stirring element, and a porous structure; this disclosure is not limiting. The foaming structure can be removed and replaced from the inlet 113 of the foaming cavity 112 to prevent clogging after prolonged use, which could affect foam output.
[0074] See Figure 1 , Figure 3 and Figure 6 As can be seen from the foregoing, the foam generating device 10 may include a foaming component 11 and a connector 12. The foaming component 11 may be directly fixed to the connector 12 or be an integrated structure. The foam generating device 10 may also include a foaming component 11 and a nozzle 13. The foaming component 11 may be directly fixed to the nozzle 13 or be an integrated structure. The foam generating device 10 may also include a foaming component 11, a connector 12, and a nozzle 13. The foaming component 11 may also be directly fixed to both the connector 12 and the nozzle 13 or be an integrated structure. This disclosure does not impose any limitations and can be configured according to actual production needs.
[0075] See Figure 1 , Figure 3 and Figure 6In one embodiment, to facilitate the installation of various foam generating devices 10, the foam generating device 10 further includes a positioning fitting 14, which is disposed on the outer wall of at least one of the nozzle 13, the foaming component 11, and the connector 12. Thus, the foam generating device 10 can be connected and assembled with the housing assembly 20 or other structures of the cleaning equipment 1 via the positioning fitting 14. For example, the positioning fitting 14 may have a snap-fit, which can mate with the housing assembly 20 or other structures of the cleaning equipment 1 to securely install the foam generating device 10. Of course, the positioning fitting 14 can also be configured with other structures, as long as it facilitates the assembly of the foam generating device 10 with other components; this disclosure does not impose any limitations.
[0076] See Figures 7 to 9 In addition to the various foam generating devices 10 described above, this disclosure also provides a cleaning device 1, which includes any of the foam generating devices 10 described above.
[0077] Taking a floor scrubber as an example, the floor scrubber has a foam cleaning mode. The floor scrubber includes a main unit 40, a housing assembly 20 connected to the main unit 40, a cleaning brush 30 mounted on the housing assembly 20, and a foam generating device 10. The main unit 40 may have a handle for the user to hold. At least one of the main unit 40 and the housing assembly 20 is also provided with liquid and gas lines respectively connected to the foam generating device 10 to deliver foaming agent and gas to the foam generating device 10 to generate foam. The cleaning brush 30 is used to clean the floor or other surfaces. The outlet of the foam generating device 10 may be directed towards the cleaning brush 30 or towards the cleaning surface; this disclosure does not impose any limitations.
[0078] Thus, when the floor scrubber is in foam cleaning mode, the liquid and gas lines respectively supply foaming agent and gas to the foam generating device 10. The foaming agent and gas generate foam in the foaming chamber 112 and output the foam to the cleaning brush 30 or the cleaning surface. Compared to liquid detergent, foam has less fluidity, allowing it to adhere to vertical surfaces or complex surfaces (such as walls or corners), enabling it to remain on dirty surfaces for a longer period, thereby dissolving and cleaning stubborn dirt. Furthermore, the floor scrubber can build up a thicker foam layer on the dirty surface, improving the persistence of dirt breakdown and thus enhancing the cleaning effect. In addition, when the floor scrubber outputs foam, users can use the foam to draw different patterns on the dirt to enhance the cleaning fun and visual appeal.
[0079] Understandably, the foam generating device 10 can be fixed to the housing assembly 20 by means of bolts, snap-fit, or threaded connection, so that the nozzle 13 of the foam generating device 10 is oriented toward the cleaning brush 30 or the cleaning surface. Alternatively, the foam generating device 10 and the housing assembly 20 can also be rotatably connected, so that the nozzle orientation of the foam generating device 10 is adjustable, which is not limited in this disclosure.
[0080] In this way, the cleaning equipment 1 can integrate all the components used for foam output through the foam generating device 10, reducing the need for additional connecting pipes between components, thus simplifying the piping layout within the cleaning equipment 1, significantly reducing the space occupied inside the cleaning equipment 1, achieving miniaturization and weight reduction, and improving the portability and flexibility of the cleaning equipment 1. Furthermore, the foam generating device 10 can also simplify the assembly process of the cleaning equipment 1, improve assembly efficiency, and help improve the production efficiency and quality control level of the cleaning equipment 1.
[0081] The technical solutions or features described in the above embodiments can be combined or complemented by each other without conflict. The scope of this disclosure is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings. All modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
