Abstract
Description
Technical Field
[0001] This application belongs to the field of cleaning technology, and more specifically, relates to a foam generator, a clean water tank, a cleaning head, and a cleaning device. Background Technology
[0002] Cleaning equipment uses cleaning brushes to clean surfaces such as floors and walls. To improve the cleaning effect, cleaning equipment usually uses a foam generator to spray foam onto the surface that needs to be cleaned.
[0003] In related technologies, foam generators use filters of different mesh sizes to form dense foam. However, the filters are usually fixedly connected and cannot be disassembled, making maintenance inconvenient when blockages occur between different filters. Utility Model Content
[0004] The purpose of this application is to provide a foam generator, a clean water tank, a cleaning head, and a cleaning device to solve the technical problem of inconvenient maintenance when different filters become clogged.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, this application provides a foam generator, including a housing, a first support member, a first filter screen, a second support member, and a second filter screen. The housing has a foam outlet. The first filter screen is disposed on the first support member, and the second filter screen is disposed on the second support member, with the second filter screen having a different mesh size than the first filter screen. At least one of the first support member and the second support member is connected to the housing. The first filter screen and the second filter screen are spaced apart to form a foam channel communicating with the foam outlet. The first support member and the second support member are separable.
[0007] With the above technical solution, since different filter screens have different mesh counts, some impurities can pass through the smaller mesh screen but not the larger mesh screen, causing them to accumulate between the screens with different mesh counts and easily become clogged. The first support member and the second support member can be separated, allowing the first and second filter screens with different mesh counts to be separated from each other, facilitating the cleaning of impurities accumulated between the first and second filter screens with different mesh counts, thus simplifying maintenance.
[0008] Therefore, the foam generator provided in this application can solve the technical problem of inconvenient maintenance when different filters become clogged.
[0009] In some embodiments, the first support member is detachably connected to the housing, and the first support member is detachably connected to the second support member. This allows the first and second support members to be separated from each other, enabling the first and second filter screens to be separated from each other. This facilitates the cleaning of impurities accumulated between the first and second filter screens, which have different mesh sizes, thus simplifying maintenance. Furthermore, the first support member can be detached from the housing, facilitating the cleaning of impurities near the first filter screen from outside the housing.
[0010] In some embodiments, the second support rests between the first support and the housing. This allows for easy disassembly of the first and second supports, facilitating the cleaning of impurities within the foam channels and thus simplifying maintenance.
[0011] In some embodiments, the housing has a first protrusion on the side facing the second support member, and the first protrusion abuts against the second support member;
[0012] And / or, the second support member has a second protrusion on the side away from the first support member, and the second protrusion abuts against the housing.
[0013] In this way, the shell and the second support can abut against each other through the first protrusion and / or the second protrusion, and there can be a gap between the shell and the second support, in which foam can accumulate, which is conducive to the continuous discharge of foam from the foam outlet.
[0014] In some implementations, the first support member and the second support member are interference-fitted.
[0015] In this way, the first and second supports can be separated from each other under external force, thus making them detachable and facilitating the cleaning of impurities in the foam channel.
[0016] In some embodiments, the first support member is provided with a mounting groove, and the second support member is disposed in the mounting groove and is interference-fitted with the side wall of the mounting groove.
[0017] This makes it easy to install and disassemble the first and second support components.
[0018] In some embodiments, the sidewall of the mounting groove is provided with a rib protruding toward the inside of the mounting groove, and the second support member is interference-fitted with the rib.
[0019] This results in a smaller contact area between the first and second support components, making disassembly easier.
[0020] In some embodiments, the side of the rib facing the inside of the mounting groove has a guide surface, which is located near the opening of the mounting groove. The guide surface is used to guide the second support member into the mounting groove. In this way, the first and second supports members are easy to install.
[0021] In some embodiments, the first support member has a first snap-fit member at the end away from the second support member, and the outer wall of the housing has a second snap-fit member, with the first snap-fit member and the second snap-fit member engaging. This facilitates the assembly and disassembly of the first support member and the housing.
[0022] In some embodiments, the foam generator provided in this application further includes a gripper for disengaging the first snap-fit member from the second snap-fit member. This allows the foam generator to apply force to the first support member using the gripper, facilitating the removal of the first support member.
[0023] In some embodiments, the gripper is rotatably connected to the first support member, and the axis of rotation is perpendicular to the extension direction of the foam channel. This rotatable connection allows the position of the gripper to be adjusted according to the usage state.
[0024] In some embodiments, the outer surface of the first support member has two connecting holes, which are arranged opposite each other along a first direction perpendicular to the extension direction of the foam channel. The grip is a pull ring, with both ends of the pull ring inserted into the connecting holes. This facilitates the assembly and disassembly of the grip and the first support member.
[0025] In some embodiments, the outer surface of the housing is provided with a first limiting portion for restricting the movement of the housing within the cleaning equipment. In this way, the foam generator provided in this application can be stably installed in the cleaning equipment via the housing.
[0026] In some embodiments, the first limiting part is provided with a clearance groove, the first support member is provided with a first snap-fit member, and the outer wall of the housing is provided with a second snap-fit member. The first snap-fit member and the second snap-fit member are snap-fitted together within the clearance groove. In this way, the first limiting part can provide an installation position for the snap-fit structure, which helps to improve the structural compactness.
[0027] In some embodiments, the first support member is sealed to the housing via a sealing structure. This prevents foam from easily leaking from the connection between the first support member and the housing.
[0028] In some embodiments, the first support member is provided with a first settling groove, and the first filter screen is disposed in the first settling groove;
[0029] And / or, the second support member is provided with a second sink, and the second filter screen is disposed in the second sink.
[0030] In this way, the first filter screen can be stably connected to the first support, and the second filter screen can be stably connected to the second support.
[0031] In some embodiments, the foam outlet is located on one side of the housing in a second direction, which is perpendicular to the extension direction of the foam channel.
[0032] In this way, the foam outlet can discharge foam outward from the second direction, and can then be connected to an external delivery pipe in the second direction, which helps to save space in the extension direction of the foam channel.
[0033] In some implementations, the second filter is closer to the foam outlet than the first filter, the mesh count of the first filter is smaller than that of the second filter, and the orthographic projection of the second filter at least partially overlaps with the orthographic projection of the foam outlet in a projection plane perpendicular to the second direction.
[0034] In this way, the foam passing through the second filter can be easily discharged from the foam outlet.
[0035] In some embodiments, the foam generator also includes a foam outlet pipe connected to the housing and communicating with the foam outlet, with the foam outlet pipe and the foam channel arranged at an angle.
[0036] Secondly, this application provides a clean water tank, including a tank body and a foam generator according to any of the above embodiments, wherein the foam generator is installed in the tank body. The clean water tank provided by this application has the same or similar technical effects as the foam generator of any of the above embodiments, which will not be described in detail here.
[0037] In some implementations, the foam generator is mounted at the bottom of the enclosure. This allows the enclosure to conceal the foam generator, preventing it from affecting the shape of the top of the enclosure.
[0038] In some embodiments, the housing is provided with a receiving cavity, and a second limiting part is provided within the receiving cavity. The second limiting part cooperates with the first limiting part of the foam generator to restrict the movement of the housing within the receiving cavity. In this way, when the foam generator has a first limiting part, the second limiting part can cooperate with the first limiting part to limit the housing, making it difficult for the housing to move within the receiving cavity.
[0039] In some embodiments, the receiving cavity is provided with an inlet and outlet for assembling a foam generator, the wall of the inlet and outlet is provided with a clearance notch, and the first snap-fit of the foam generator passes through the clearance notch.
[0040] In this way, the first snap-fit component passes through the clearance notch, and the diameter of the inlet and outlet holes can be reduced. This means that the foam generator can be assembled in the clean water tank using a smaller diameter inlet and outlet hole, which is beneficial to the structural compactness. Furthermore, the first support component can be detached from the housing, which facilitates external cleaning of the filter screen.
[0041] In some embodiments, the clear water tank provided in this application includes a nozzle and a delivery pipe, the delivery pipe connecting the nozzle and a foam outlet. The nozzle and foam outlet are distributed along a second direction, which is perpendicular to the extending direction of the foam channel. This allows the clear water tank to discharge foam through the nozzle, and also improves structural compactness.
[0042] In some embodiments, the bottom of the housing has a recess for accommodating the grip of the foam generator. This allows the grip to be concealed within the recess when the foam generator has a grip, facilitating the fit between the housing and other components and promoting structural compactness.
[0043] In some embodiments, the housing further includes a third limiting portion disposed within the groove, the third limiting portion being used to prevent the gripper from detaching from the groove. This prevents the gripper from freely detaching from the groove.
[0044] Thirdly, this application provides a cleaning head, including the clean water tank of any of the above embodiments. The cleaning head provided by this application has the same or similar technical effects as the clean water tank of any of the above embodiments, and will not be described in detail here.
[0045] Thirdly, this application provides a cleaning device including the cleaning head of the above-described embodiments. The cleaning device provided by this application has the same or similar technical effects as the cleaning head of the above-described embodiments, and will not be described in detail here.

[0066] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

Therefore, they should not be construed as limitations on this application.
[0069] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0070] Cleaning equipment uses cleaning brushes to clean surfaces such as floors and walls. To improve the cleaning effect, cleaning equipment usually uses a foam generator to spray foam onto the surface that needs to be cleaned.
[0071] In related technologies, foam generators utilize filters with different mesh sizes to form dense foam. Because the mesh sizes of the filters differ, some particles can pass through smaller mesh filters but not larger mesh filters, causing them to accumulate between filters of different mesh sizes and easily leading to clogging. However, the filters are usually fixedly connected and cannot be disassembled, making maintenance inconvenient when clogging occurs between different filters.
[0072] To solve the above-mentioned technical problems, this application provides a foam generator, a clean water tank, a cleaning head, and a cleaning device.
[0073] Please see Figure 1 and Figure 2 This application provides a foam generator 100, which includes a housing 10 and a foam outlet 101, through which the foam generated by the foam generator 100 can be discharged.
[0074] The foam generator 100 also includes a first support member 20 and a second support member 30, at least one of which is connected to the housing 10, such that the housing 10, the first support member 20 and the second support member 30 form part of the foam generator 100.
[0075] In addition, the first filter screen 40 is disposed on the first support member 20, and the second filter screen 50 is disposed on the second support member 30. The first filter screen 40 and the second filter screen 50 are spaced apart and form a foam channel 102 that communicates with the foam outlet 101. In this way, the cleaning medium formed by the cleaning agent and air can enter the foam channel 102 and accumulate after passing through the foam formed by the first filter screen 40, and then pass through the second filter screen 50 to form foam.
[0076] The second filter 50 has a different mesh size than the first filter 40; for example, the mesh size of the second filter 50 is greater than that of the first filter 40, meaning the mesh size of the second filter 50 is smaller than that of the first filter 40. The cleaning medium can first pass through a filter with a smaller mesh size (e.g., the first filter 40) to form a looser foam, and then pass through a filter with a larger mesh size (e.g., the second filter 50) to form a denser foam. In this way, the foam generator 100 provided in this embodiment can form dense foam.
[0077] However, the inventors discovered that because different filter screens have different mesh counts, some impurities can pass through a filter screen with a smaller mesh count (e.g., the first filter screen 40) but cannot pass through a filter screen with a larger mesh count (e.g., the second filter screen 50). As a result, impurities accumulate between filter screens with different mesh counts (within the foam channel 102), which can easily cause blockages.
[0078] In the foam generator 100 provided in this application embodiment, the first support member 20 and the second support member 30 can be separated, which can separate the filter screens of different mesh sizes (e.g., the first filter screen 40 and the second filter screen 50) from each other, making it easier to clean the impurities accumulated between the filter screens of different mesh sizes, thereby facilitating maintenance.
[0079] Optionally, the foam generator 100 provided in this embodiment may further include a third support member and a third filter (not shown in the figure). The third filter is disposed on the third support member, which may be separable from the first support member 20 and / or the second support member 30. The mesh size of the third filter can be between that of the first filter 40 and the second filter 50, and the third filter can be located between the first filter 40 and the second filter 50; alternatively, the mesh size of the third filter can be greater than that of the second filter 50, and the third filter can be located on the side of the second filter 50 away from the first filter 40; or alternatively, the mesh size of the third filter can be less than that of the first filter 40, and the third filter can be located on the side of the first filter 40 away from the second filter 50. In this way, the foam size can be gradually reduced, facilitating the formation of dense foam.
[0080] Of course, the foam generator 100 provided in this application embodiment may also include more filters and supports, such as a fourth support and a fourth filter. Different supports can be separated from each other, so that filters installed on different supports can also be separated from each other, thereby facilitating the cleaning of impurities.
[0081] Please continue reading. Figure 2 In some embodiments, the first support member 20 is detachably connected to the housing 10. This allows the first support member 20 to be detached from the housing 10, enabling it to clean impurities near the first filter screen 40 from a location away from the housing 10, facilitating maintenance.
[0082] Optionally, the first support member 20 and the housing 10 can be detachably connected by bolts, clips or other connection structures.
[0083] For example, the first support member 20 has a first snap-fit member 61 at the end away from the second support member 30, and the outer wall of the housing 10 has a second snap-fit member 62. The first snap-fit member 61 and the second snap-fit member 62 are snap-fit connected. That is, the foam generator 100 provided in this application embodiment includes a snap-fit structure 60, which includes a first snap-fit member 61 and a second snap-fit member 62 that are snap-fit connected. The first snap-fit member 61 is disposed at the end of the first support member 20 away from the second support member 30, and the second snap-fit member 62 is disposed on the outer wall of the housing 10. One of the first snap-fit member 61 and the second snap-fit member 62 has a snap-fit protrusion, and the other has a snap-fit groove that mates with the snap-fit protrusion.
[0084] For example, a card protrusion is provided on the first card connector 61, and a card slot is provided on the second card connector 62.
[0085] For example, a card slot is provided on the first card connector 61, and a card protrusion is provided on the second card connector 62.
[0086] Understandably, when the first support member 20 is subjected to an external force in a direction away from the housing 10, the first latching member 61 elastically deforms under the pressure of the second latching member 62, and the latching protrusion can disengage from the latching groove, thereby disengaging the first support member 20 from the housing 10. Similarly, when the first support member 20 is installed with the housing 10, the first support member 20 is subjected to an external force in a direction close to the housing 10, and the first latching member 61 can deform under the pressure of the outer surface of the housing 10. After the first latching member 61 reaches the latching position, the deformation of the first latching member 61 recovers, allowing the latching protrusion to engage with the latching groove. Therefore, the first support member 20 and the housing 10 are easy to assemble and disassemble.
[0087] Please continue reading. Figure 2 In some embodiments, the foam generator 100 provided in this application also includes a gripper 70, so that the foam generator 100 provided in this application can use the gripper 70 to apply force to the first support member 20, making it easier to disassemble the first support member 20.
[0088] Optionally, the grip 70 is rotatably connected to the first support 20, and the axis of rotation is perpendicular to the extension direction of the foam channel 102 (e.g., the Z direction). In this way, the grip 70 is rotatably connected to the first support 20, and the position of the grip 70 can be adjusted according to the usage state.
[0089] Optionally, the outer surface of the first support member 20 is provided with two connecting holes 201, which are arranged opposite each other along a first direction (X direction in the figure). The first direction is perpendicular to the extension direction of the foam channel 102. The grip member 70 is a pull ring, and the two ends of the pull ring are inserted into the connecting holes 201. In this way, the grip member 70 and the first support member 20 are easy to assemble and disassemble.
[0090] Optionally, the pull ring has a C-shaped structure, and connecting rods are provided at both ends of the pull ring, with the connecting rods inserted into the connecting holes 201.
[0091] In some embodiments, the first support member 20 is sealed to the housing 10 via a sealing structure 80. This prevents foam from easily leaking from the connection between the first support member 20 and the housing 10.
[0092] Optionally, the sealing structure 80 includes a sealing ring 81 and a sealing groove 82, the sealing ring 81 is installed in the sealing groove 82, the sealing groove 82 is disposed in one of the first support member 20 and the housing 10, and the sealing ring 81 abuts against the other of the first support member 20 and the housing 10.
[0093] For example, the sealing groove 82 is disposed on the first support member 20, and the sealing ring 81 abuts against the housing 10.
[0094] For example, the sealing groove 82 is disposed on the housing 10, and the sealing ring 81 abuts against the first support member 20.
[0095] Optionally, both the sealing groove 82 and the sealing ring 81 are annular and are arranged around the foam channel 102.
[0096] Please continue reading. Figure 2 In some embodiments, the outer surface of the housing 10 is provided with a first limiting portion 11 for restricting the movement of the housing 10 within the cleaning equipment. The first limiting portion 11 can be a protrusion or a recess on the outer surface of the housing 10. In this way, the foam generator 100 provided in this application can be limited by the first limiting portion 11 of the housing 10, preventing the foam generator 100 from moving within the cleaning equipment, and the foam generator 100 can be stably installed within the cleaning equipment using the housing 10.
[0097] Optionally, the first limiting part 11 is provided with a relief groove 1101, the first support member 20 is provided with a first snap-fit member 61, and the outer wall of the housing 10 is provided with a second snap-fit member 62. The first snap-fit member 61 and the second snap-fit member 62 are snapped together in the relief groove 1101. In this way, the first limiting part 11 can provide a connection position for the first snap-fit member 61 and the second snap-fit member 62, which helps to improve the structural compactness.
[0098] Optionally, there can be two first limiting parts 11, and the two first limiting parts 11 are arranged opposite each other along the first direction.
[0099] Optionally, the number of first limiting parts 11 may be greater than or equal to three, and the first limiting parts 11 may be arranged at intervals around the housing 10.
[0100] Please continue reading. Figure 2 In some embodiments, the first support member 20 and the second support member 30 are detachably connected. This allows the first support member 20 and the second support member 30 to be separated from each other, and the first filter screen 40 and the second filter screen 50 to be separated from each other, facilitating the cleaning of impurities accumulated between the first filter screen 40 and the second filter screen 50 with different mesh sizes, thereby simplifying maintenance.
[0101] Optionally, the first support member 20 and the second support member 30 can be detachably connected to the housing 10, thereby allowing the first support member 20 and the second support member 30 to be separated from each other, and thus allowing the first filter screen 40 and the second filter screen 50 to be separated from each other.
[0102] Optionally, one of the first support member 20 and the second support member 30 can be detachably connected to the housing 10, and the other can be fixedly connected to the housing 10. This also allows the first support member 20 and the second support member 30 to be separated from each other, thereby allowing the first filter screen 40 and the second filter screen 50 to be separated from each other.
[0103] Please continue reading. Figure 2In some embodiments, the second support member 30 abuts against the first support member 20 and the housing 10. In this way, the first support member 20 and the second support member 30 are in contact, which facilitates disassembly, thereby facilitating the cleaning of impurities in the foam channel 102 and thus facilitating maintenance.
[0104] Optionally, the housing 10 has a first protrusion 12 on the side facing the second support member 30, and the first protrusion 12 abuts against the second support member 30. There can be multiple first protrusions 12, which are spaced apart circumferentially along the foam channel 102. This allows foam to pass through the gap between two adjacent first protrusions 12, which helps to prevent foam from accumulating between the first protrusions 12 and the second support member 30.
[0105] Optionally, the second support member 30 has a second protrusion 31 on the side away from the first support member 20, and the second protrusion 31 abuts against the housing 10. Similarly, there can be multiple second protrusions 31, and the multiple second protrusions 31 are arranged at intervals along the circumference of the foam channel 102.
[0106] Optionally, the housing 10 has a first protrusion 12 on the side facing the second support member 30, and the second support member 30 has a second protrusion 31 on the side away from the first support member 20. The first protrusion 12 and the second protrusion 31 abut against each other, so that the second support member 30 abuts against the first support member 20 and the housing 10.
[0107] In this way, the housing 10 and the second support member 30 can abut against each other through the first protrusion 12 and / or the second protrusion 31, and there can be a gap between the housing 10 and the second support member 30, in which foam can accumulate, which is conducive to the continuous discharge of foam from the foam outlet 101.
[0108] Please continue reading. Figure 2 In some embodiments, the first support member 20 and the second support member 30 are interference-fitted, so that the first support member 20 and the second support member 30 can be separated from each other under external force, thereby being disassembled, which facilitates the cleaning of impurities in the foam channel 102.
[0109] It is understandable that when the first support member 20 and the second support member 30 are installed, the second support member 30 can be press-fitted with the first support member 20 against the housing 10. When the first support member 20 is detached from the housing 10, the second support member 30 can also detach from the housing 10. In this way, the first support member 20 and the second support member 30 can be separated from the housing 10 by external force, which is convenient for cleaning impurities from the outside.
[0110] Optionally, based on the interference fit between the first support member 20 and the second support member 30, the first support member 20 can be interference fitted with the housing 10, so that the first support member 20 can be separated from the housing 10 and the second support member 30 under the action of external force.
[0111] Optionally, based on the interference fit between the first support member 20 and the second support member 30, the second support member 30 can also be interference-fitted with the housing 10. This allows the first support member 20 to detach from the second support member 30 under external force. It is understood that the cooperating force between the first support member 20 and the second support member 30 is greater than the cooperating force between the second support member 30 and the housing 10. Therefore, when the first support member 20 is subjected to external force, the second support member 30 can detach from the housing 10, while the first support member 20 and the second support member 30 remain in an interference fit. After the second support member 30 detaches from the housing 10, the first support member 20 and the second support member 30 can then detach from each other outside the housing 10.
[0112] Optionally, based on the interference fit between the first support member 20 and the second support member 30, the first support member 20 can also be interference fitted with the housing 10, and the second support member 30 can also be interference fitted with the housing 10. It is understood that when the first support member 20 is subjected to an external force, the first support member 20 can detach from both the second support member 30 and the housing 10, or the first support member 20 can detach from the housing 10 together with the second support member 30.
[0113] Optionally, the first support member 20 may be provided with a first channel 205, and the first filter 40 is located at one end of the first channel 205. The second support member 30 may be provided with a second channel 302, and the second filter 50 is located at one end of the second channel 302. The other end of the first channel 205 may be connected to the other end of the second channel 302, thereby forming a foam channel 102.
[0114] Optionally, the first support member 20 is provided with a mounting groove 202, and the second support member 30 is disposed in the mounting groove 202, and the second support member 30 is interference-fitted with the side wall of the mounting groove 202.

[0122] In this way, foam outlet 101 can discharge foam outward from the second direction, and can then be connected to an external delivery pipe 400 in the second direction, which helps to save space in the extension direction of foam channel 102 and improves structural compactness.
[0123] Optionally, compared to the first filter 40, the second filter 50 is closer to the foam outlet 101, the mesh number of the first filter 40 is smaller than that of the second filter 50, and in the projection plane perpendicular to the second direction, the orthographic projection of the second filter 50 and the orthographic projection of the foam outlet 101 at least partially overlap.
[0124] In this way, the second filter 50 can expose at least part of the foam outlet 101, and the foam formed after the cleaning medium passes through the first filter 40 can enter the foam channel 102. The foam in the foam channel 102 can be discharged from the foam outlet 101 after being refined by the second filter 50.
[0125] Please continue reading. Figure 5 In some embodiments, the foam generator 100 further includes a foam outlet pipe 90, which is connected to the housing 10 and communicates with the foam outlet 101. The foam outlet pipe 90 is arranged at an angle to the foam channel 102. Optionally, the extending direction of the foam outlet pipe 90 is perpendicular to the extending direction of the foam channel 102, for example, the foam outlet pipe 90 extends along a second direction. In this way, the foam outlet pipe 90 can be connected to an external delivery pipe 400 along the second direction, which helps to save space in the extending direction of the foam channel 102, thereby contributing to structural compactness.
[0126] Please see Figure 6 This application also provides a clean water tank 1000, which includes a tank body 200 and a foam generator 100 from any of the above embodiments, the foam generator 100 being installed in the tank body 200. The clean water tank 1000 provided in this application has the same or similar technical effects as the foam generator 100 from any of the above embodiments, and will not be described in detail here.
[0127] Please see Figure 6 and Figure 7 In some embodiments, the foam generator 100 is mounted on the bottom of the housing 200. Optionally, the housing 200 includes a mounting shell 210 located at the bottom for mounting the foam generator 100. In this way, the housing 200 can conceal the foam generator 100, thus avoiding affecting the shape of the top of the housing 200.
[0128] Please see Figure 7 and Figure 8 In some embodiments, the housing 200 is provided with a receiving cavity 2001, and a second limiting part 220 is provided inside the receiving cavity 2001. The second limiting part 220 cooperates with the first limiting part 11 of the foam generator 100 to restrict the movement of the housing 10 within the receiving cavity 2001. That is, when the foam generator 100 has the first limiting part 11, the second limiting part 220 can cooperate with the first limiting part 11 to limit the housing 10, making it difficult for the housing 100 to move within the receiving cavity 2001, thus preventing the housing from shaking within the receiving cavity 2001.
[0129] In some embodiments, the receiving cavity 2001 is provided with an inlet / outlet hole 2002 for assembling the foam generator 100. The housing 10 is disposed within the receiving cavity 2001. A first support member 20 extends out of the inlet / outlet hole 2002. The wall of the inlet / outlet hole 2002 is provided with a clearance notch 2003. A first snap-fit member 61 passes through the clearance notch 2003. In this way, the diameter of the inlet / outlet hole 2002 can be reduced by the first snap-fit member 61 passing through the clearance notch 2003. That is, the clean water tank 1000 can assemble the foam generator 100 using the smaller diameter inlet / outlet hole 2002, which is beneficial to the structural compactness. Furthermore, the first support member 20 can be detached from the housing 10, which is beneficial for cleaning the filter screen from the outside.
[0130] It is understood that the first support member 20 is detachably connected to the housing 10, the housing 10 is disposed within the receiving cavity 2001, the first support member 20 extends out of the inlet / outlet hole 2002, and the housing 200 is provided with a second limiting part 220 located within the receiving cavity 2001. The second limiting part 220 cooperates with the first limiting part 11 of the housing 10 to restrict the movement of the housing 10 within the receiving cavity 2001. The mounting shell 210 includes a first mounting shell 211 and a second mounting shell 212. The receiving cavity 2001 is disposed inside the first mounting shell 211, and the bottom of the receiving cavity 2001 has an opening. The second mounting shell 212 is connected to the first mounting shell 211 and seals the opening at the bottom of the receiving cavity 2001. The inlet / outlet hole 2002 is disposed on the second mounting shell 212.
[0131] It is understood that the second limiting part 220 can abut against the first limiting part 11 in the extending direction of the foam channel 102, thereby limiting the first limiting part 11, so as to prevent the shell 10 from moving in the receiving cavity 2001.
[0132] Optionally, please refer to the following as well. Figure 8 , Figure 9 and Figure 10 The second limiting part 220 can be divided into two parts, namely, the second limiting part 220 can include a first limiting sub-part 221 and a second limiting sub-part 222. The first limiting sub-part 221 is disposed on the first housing 10, and the second limiting sub-part 222 is disposed on the second housing 10. The first limiting part 11 abuts against the first limiting sub-part 221 and the second limiting sub-part 222.
[0133] In some embodiments, the clean water tank 1000 provided in this application includes a nozzle 300 and a delivery pipe 400, the delivery pipe 400 connecting the nozzle 300 and the foam outlet 101. The nozzle 300 and the foam outlet 101 are distributed along a second direction, which is perpendicular to the extending direction of the foam channel 102. In this way, the clean water tank 1000 provided in this application can deliver the foam generated by the foam generator 100 to the nozzle 300 through the delivery pipe 400, and then discharge the foam outward through the nozzle 300, which is beneficial to improving the structural compactness.
[0134] Alternatively, the delivery pipe 400 can be a flexible hose, and the delivery pipe 400 can be deformed to avoid other components.
[0135] Optionally, the foam generator 100 is positioned directly opposite the nozzle 300, which shortens the distance between the foam generator 100 and the nozzle 300, thereby saving on the delivery pipe 400.
[0136] Alternatively, please continue reading Figure 8 In some embodiments, the bottom of the housing 200 is provided with a groove 2121 for accommodating the grip 70 of the foam generator 100, wherein the groove 2121 is located at the bottom of the second mounting shell 212. In this way, when the foam generator 100 has the grip 70, the grip 70 can be hidden inside the groove 2121, which is beneficial for the cooperation between the housing 200 and other components, and also for structural compactness.
[0137] Optionally, the housing 200 further includes a third limiting portion 2122 disposed within the groove 2121. The third limiting portion 2122 is used to restrict the gripper 70 from disengaging from the groove 2121, thus preventing the gripper 70 from freely disengaging from the groove 2121. The third limiting portion 2122 may be disposed on the side wall and / or bottom wall of the groove 2121. It is understood that when the gripper 70 is subjected to an external force, a force is generated between the gripper 70 and the third limiting portion 2122, and at least one of the gripper 70 and the third limiting portion 2122 can elastically deform, thereby allowing the gripper 70 to disengage from the groove 2121 under the action of the external force.
