Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a connecting structure and a sweeping and mopping integrated cleaning device. Background Technology

[0002] The sweeping and mopping cleaning equipment has a flow channel. When the sweeping and mopping cleaning equipment is working, the wastewater generated during mopping will carry certain solid impurities into the flow channel. After flowing through the self-cleaning component of the sweeping and mopping cleaning equipment, it will be transformed into clean water and then flow back to the sweeping and mopping components through the flow channel. This cycle allows the sweeping and mopping cleaning equipment to effectively clean the floor.

[0003] Solid impurities can enter the flow path with the water flow. If solid impurities get stuck in the flow path, it will cause blockage, which will affect the normal operation of the sweeping and mopping cleaning equipment and affect the customer's experience of using the sweeping and mopping cleaning equipment. Utility Model Content

[0004] In view of this, and in response to the above-mentioned technical problems, this application provides a connecting structure and a sweeping and mopping integrated cleaning device, wherein the connecting structure can be applied to the sweeping and mopping integrated cleaning device.

[0005] A first aspect of this application provides a connection structure including a support housing, a filter plate assembly, and a filter comb assembly. The support housing includes a flow connection portion, a flow channel portion, and a fluid outlet portion, all sequentially connected in a first direction within its inner cavity. The filter plate assembly has a flow chamber and a wastewater through-hole communicating with the flow chamber, the wastewater through-hole communicating with an external space. The filter plate assembly is connected to the support housing. The flow chamber of the filter plate assembly communicates with the inner cavity of the flow channel portion in a second direction, the first direction being perpendicular to the second direction. The wastewater through-hole allows wastewater to enter the flow chamber, and the flow channel portion allows wastewater within the flow chamber to flow towards the inner cavity of the fluid outlet portion. The filter comb assembly includes filter comb portions and a positioning connection portion connected in the first direction. At least a portion of the positioning connection portion is located within the inner cavity of the flow connection portion and is assembled with the flow connection portion. The filter comb portions are located within the inner cavity of the flow channel portion and are used to filter solid impurities in the wastewater flowing through the flow channel portion.

[0006] In this application, the inner cavity structure of the supporting shell is connected to the flow chamber of the filter plate assembly. Thus, wastewater enters the flow chamber through the wastewater through-hole, flows along the flow chamber to the inner cavity structure of the supporting shell, and then exits the chamber from the wastewater outlet of the fluid outlet. When the wastewater passes through the inner cavity of the flow channel, it flows through the filter comb teeth. Solid impurities (such as hair, paper scraps, etc.) in the wastewater are intercepted and attached to the filter comb teeth. This effectively reduces the amount of solid impurities carried in the wastewater discharged from the wastewater outlet. Therefore, when the wastewater enters the return pipe of the sweeping and mopping integrated cleaning device, a large amount of solid impurities will not enter with the wastewater and cause blockage of the return pipe. This ensures a good user experience and extends the service life of the sweeping and mopping integrated cleaning device.

[0007] The second aspect of this application provides a sweeping and mopping integrated cleaning device, which includes the connection structure described in the first aspect of this application.

[0008] The main beneficial effects of the second aspect are detailed in the first aspect, and will not be repeated here. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] The following will refer to the appendices in the embodiments of this application. Figure 1 - Appendix Figure 10 The technical solutions in the embodiments of this application are clearly and completely described. The coordinate directions in each map correspond to the geometric directions of the connecting structure 1. That is, the first direction X in the map corresponds to the length direction of the connecting structure 1, the third direction Y in the map corresponds to the width direction of the connecting structure 1, and the second direction Z in the map corresponds to the height direction of the connecting structure 1. For the geometric direction description of the local structure, please refer to the direction of the connecting structure 1.

[0027] Please refer to this first. Figure 1 This application provides a sweeping and mopping integrated cleaning device 1000, which includes a connecting structure 1. Please refer to [the relevant documentation]. Figures 2 to 10 The connection structure 1 includes a support housing 10, a filter plate assembly 11, and a filter comb assembly 12. The support housing 10 includes a flow connection portion 100, a flow channel portion 101, and a fluid outlet portion 102 that are sequentially connected in the first direction X. It should be understood that the flow connection portion 100, the flow channel portion 101, and the fluid outlet portion 102 are all solid structures that serve as the actual carrier structure for the multiple interconnected cavities of the support housing 10.

[0028] The filter plate assembly 11 has a flow chamber 110 and a sewage through hole 111 communicating with the flow chamber 110. The sewage through hole 111 communicates with the external space. The filter plate assembly 11 is connected to the support housing 10. The flow chamber 110 of the filter plate assembly 11 (e.g., Figure 8(As shown) The inner cavity of the flow channel 101 is connected along the second direction Z. The first direction X is perpendicular to the second direction Z. The sewage through hole 111 is used for sewage to enter the flow chamber 110. The flow channel 101 is used to allow sewage in the flow chamber 110 to flow to the inner cavity of the fluid outlet 102. The filter comb assembly 12 includes a filter comb portion 120 and a positioning connection portion 121 connected along the first direction X. At least a portion of the positioning connection portion 121 is located in the inner cavity of the flow connection portion 100 and is assembled and connected to the flow connection portion 100. The filter comb portion 120 is located in the inner cavity of the flow channel 101 and is used to filter solid impurities in the sewage flowing through the flow channel 101.

[0029] In the above embodiment, the inner cavity structure of the support housing 10 is connected to the flow chamber 110 of the filter plate assembly 11. Thus, after sewage enters the flow chamber 110 through the sewage through-hole 111, it flows along the flow chamber 110 to the inner cavity structure of the support housing 10, and then exits the cavity from the sewage outlet of the fluid outlet 102. When the sewage passes through the inner cavity of the flow channel 101, it flows through the filter comb 120. Solid impurities (such as hair, paper scraps, etc.) in the sewage can be intercepted and attached to the filter comb 120. Therefore, the content of solid impurities carried in the sewage discharged from the sewage outlet of the fluid outlet 102 is effectively reduced. Consequently, after the sewage enters the return pipe of the sweeping and mopping integrated cleaning device 1000, a large amount of solid impurities will not cause blockage of the return pipe. Therefore, the user experience of using the sweeping and mopping integrated cleaning device 1000 is optimized, and the service life of the sweeping and mopping integrated cleaning device 1000 is extended.

[0030] Please refer to Figures 2 to 5 Optionally, the support housing 10 includes a support plate 103 and a lateral connecting plate 104 arranged intersecting each other. The support plate 103 is supported on the back of the filter plate assembly 11. The lateral connecting plate 104 includes a flow channel portion 101, a flow connection portion 100, and a fluid outlet portion 102. The side of the lateral connecting plate 104 facing the filter plate assembly 11 has a fluid through hole 108. The fluid through hole 108 communicates between the flow channel portion 101 and the flow connection portion 100 along the second direction Z. In this way, after sewage enters the flow chamber 110, it can enter the inner cavity of the flow channel portion 101 through the fluid through hole 108 and then flow out through the sewage outlet of the fluid outlet portion 102.

[0031] Along the second direction Z, the fluid through hole 108 connects the flow channel portion 101 and the flow connection portion 100. It can be understood that the fluid through hole 108 is located between the flow channel portion 101 and the flow connection portion 100. The inner cavity of the flow channel portion 101 is mainly used to allow sewage to flow to the inner cavity of the fluid outlet portion 102. The flow connection portion 100 is used to connect the filter comb assembly 12 to filter impurities in the sewage entering the inner cavity of the flow channel portion 101, and together with the shell portion of the support housing 10, it constrains the sewage to prevent it from flowing out of the flow connection portion 100.

[0032] For reference Figure 4 and Figure 5 Furthermore, in the second direction Z, at least a portion of the filter comb portion 120 corresponds to the opening of the fluid through hole 108 toward the flow channel portion 101. The filter comb portion 120 includes a plurality of spaced comb teeth that extend along the second direction Z.

[0033] Because the sewage is restricted by the walls of the flow chamber 110, it needs to flow along the first direction X in the figure to enter the inner cavity of the side connecting plate 104. Since the comb teeth extend along the second direction Z, and the first direction X is perpendicular to the second direction Z, the comb teeth are set perpendicular to the flow trend direction of the sewage. Since the solid impurities carried in the sewage flow with the sewage, that is, the solid impurities also move along the first direction X, the solid impurities can be intercepted by the comb teeth during the movement and hung on the surface of the comb teeth. Thus, the filter comb tooth section 120 can effectively intercept the solid impurities in the sewage and effectively prevent the solid impurities from continuing to move into the return pipe of the sweeping and mopping integrated device.

[0034] For reference Figure 5 Furthermore, the inner diameter of the flow connection portion 100 is larger than the inner diameter of the flow channel portion 101, and a stepped limiting surface 105 is formed between the flow connection portion 100 and the flow channel portion 101. The positioning connection portion 121 abuts against the stepped limiting surface 105 and connects to the inner sidewall of the flow channel portion 101, and the surface of the positioning connection portion 121 facing away from the filter comb portion 120 is exposed on the bottom surface of the side connecting plate 104. The user can directly observe the positioning connection portion 121 on the surface of the support housing 10. When the user needs to remove the filter comb assembly 12 to clean the solid impurities of the filter comb portion 120, the user can find the positioning connection portion 121 more quickly and accurately.

[0035] The stepped limiting surface 105 can constrain the positioning connection part 121 in the filter comb assembly 12. When the user installs the filter comb assembly 12 to the flow connection part 100 of the support housing 10, when the positioning connection part 121 abuts against the stepped limiting surface 105, since the user can no longer push the positioning connection part 121 along the second direction Z, the user can determine that the filter comb assembly 12 is installed in the target position. In other words, the setting of the stepped limiting surface 105 can effectively remind the user whether the filter comb assembly 12 is installed in place, thus improving the user experience.

[0036] Please refer to this as well. Figure 6 , Figure 7 , Figure 9 and Figure 10 Optionally, the filter comb assembly 12 further includes a snap-fit ​​portion 122, which is connected to the side of the positioning connection portion 121. The lateral connecting plate 104 also has a slot 106, which is located on the outside of the flow connection portion 100, and at least a portion of the snap-fit ​​portion 122 is located within the slot 106. The lateral connecting plate 104 also includes a limiting rib 107 provided on the inner wall of the slot 106, and an engaging rib 123 is provided on the side of the snap-fit ​​portion 122 opposite to the positioning connection portion 121, the engaging rib 123 engaging with the limiting rib 107.

[0037] Since the snap-fit ​​part 122 can be engaged with the side connecting plate 104, and the snap-fit ​​rib 123 of the snap-fit ​​part 122 can be engaged with the limiting rib 107 on the inner wall of the slot 106, the snap-fit ​​part 122 can provide a connection between the filter comb assembly 12 and the support housing 10, so that the filter comb assembly 12 can be stably engaged with the fluid connection part, and the filter comb part 120 can be stably located in the inner cavity of the flow channel part 101 to filter solid impurities in sewage.

[0038] In addition, users can quickly remove or install the filter comb assembly 12 onto the support housing 10 by operating the latching part 122. This not only meets the filtering operation of the filter comb assembly 12 for sewage, but also allows users to quickly disassemble and install the filter comb assembly 12 when they need to clean the solid impurities attached to the filter comb part 120.

[0039] For reference Figure 7 , Figure 9 and Figure 10Furthermore, the filter comb assembly 12 also includes a sealing connector 124 connecting the filter comb portion 120. The sealing connector 124 is interference-fitted to the inner wall of the flow channel portion 101. In this way, sewage is difficult to flow from the gap between the sealing connector 124 and the inner wall of the flow channel portion 101 to the fluid connection portion, and sewage will not flow out from the fluid connection portion, thus affecting the working effect of the sweeping and mopping integrated cleaning equipment 1000.

[0040] The filter comb assembly 12 also includes a comb connecting seat 125, which protrudes from the positioning connecting part 121 on the side facing the filter comb part 120. The comb connecting seat 125 is assembled and connected with the sealing connecting seat 124. When the filter comb part 120 is deformed or aged, or when solid impurities attached to its comb teeth are difficult to clean and affect the subsequent use of the filter comb part 120, the user can replace the filter comb part 120 and the comb connecting seat 125 himself. In this way, the maintenance cost of the filter comb assembly 12 can be saved, and the subsequent operation effect of the filter comb assembly 12 can be met.

[0041] Furthermore, the filter comb 120 is an elastic structure, that is, the filter comb 120 has a certain deformation capability. Thus, when the filter comb 120 enters the inner cavity of the fluid channel, if structural interference occurs between the comb and the inner cavity wall of the fluid channel, the filter comb 120 can reduce the impact of structural interference on its own assembly by appropriate deformation.

[0042] Furthermore, the sealing connector 124 is an elastic structure. Thus, when the comb connector 125 and the sealing connector 124 are assembled and connected, the sealing connector 124 can be smoothly assembled to the comb connector 125 through its own elastic deformation, which reduces the difficulty of assembling and connecting the comb connector 125 and the sealing connector 124.

[0043] For reference Figure 7 , Figure 9 and Figure 10 Optionally, the surface of the sealing connection seat 124 is provided with circumferential ribs 126, which are interference-connected to the side wall of the flow channel. In this way, sewage is difficult to flow from the gap between the inner side wall of the sealing connection seat 124 and the flow channel 101 to the fluid connection part, so that sewage will not flow out from the fluid connection part and affect the working effect of the sweeping and mopping integrated cleaning equipment 1000.

[0044] Optionally, the inner wall of the supporting housing 10 is also provided with a roller connecting part (not shown). The sweeping and mopping integrated cleaning device 1000 also includes a cleaning roller assembly 2, which is rotatably connected to the roller connecting part (not shown) and pressed against the filter plate assembly 11. This allows the sewage and solid impurities absorbed in the cleaning roller assembly 2 to be squeezed and scraped away from the cleaning roller assembly 2 and enter the flow chamber 110 through the sewage through hole 111. Thus, when the sweeping and mopping integrated cleaning device 1000 is in operation, the filter plate assembly 11 squeezes the cleaning roller assembly 2, allowing the water in the cleaning roller assembly 2 and the solid impurities attached to its surface to enter the flow chamber 110 through the sewage through hole 111.

[0045] For reference Figure 8 Furthermore, the surface of the filter plate assembly 11 is provided with extrusion protrusions 112. When the sweeping and mopping integrated cleaning equipment 1000 is in operation, the extrusion protrusions 112 extrude and deform the surface of the cleaning roller assembly 2. The extrusion protrusions 112 can increase the degree of deformation of the surface of the cleaning roller assembly 2, so that the sewage absorbed in the cleaning roller assembly 2 can be squeezed out more thoroughly and enter the flow chamber 110 through the sewage passage 111.
