Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a cleaning device. Background Technology

[0002] In existing cleaning devices, a connecting pipe connects a first accommodating space inside the housing to the outside of the housing, allowing external contaminants to be drawn into the first accommodating space. A wastewater tank can be installed within the first accommodating space to collect the contaminants. The housing includes a main body and a detachable cover attached to the main body. The connecting pipe includes a first tube connected to the main body and a second tube connected to the cover. Due to manufacturing tolerances, misalignment is prone to occur during the connection process between the first and second tubes, making it difficult for them to fit completely together, thus compromising the sealing performance of the connecting pipe. In actual use, this poor sealing can cause contaminants to leak from the joint between the first and second tubes, seeping into the area outside the wastewater tank within the first accommodating space, negatively impacting the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a cleaning device to solve the problem that misalignment can easily occur when the first and second pipes are connected, resulting in poor sealing of the connecting pipe.

[0010] As a further improvement of this utility model, a first arc surface is formed on the side of the first abutting part facing the second abutting part, and a second arc surface is formed on the side of the second abutting part facing the first abutting part to cooperate with the first arc surface. When the first abutting part and the second abutting part abut against each other in the first direction, the first arc surface and the second arc surface come into contact.

[0011] As a further improvement of this utility model, the second joining structure includes a tube body portion and a connecting portion connecting the tube body portion and the second tube body. The guide cavity is formed inside the tube body portion. The second abutting portion is located on the side of the tube body portion away from the connecting portion. Furthermore, in the direction approaching the tube body portion, the inner diameter of the second abutting portion gradually decreases.

[0012] As a further improvement of this utility model, the second joining structure also includes a reinforcing rib connected to the periphery of the tube body portion, the reinforcing rib being arranged around the tube body portion.

[0013] As a further improvement of this utility model, the second joining structure is made of a flexible material.

[0014] As a further improvement of this utility model, the first tube body and the first joint structure are integrally formed.

[0015] As a further improvement of this utility model, a second accommodating space is also formed inside the housing, and the cleaning device further includes:

[0016] A suction motor, disposed within the second accommodating space, is used to generate negative pressure to form a fluid channel that passes at least partially through the first accommodating space and the second accommodating space in sequence.

[0017] A sludge container, located within the first accommodating space, is used to collect sludge through the sludge inlet when fluid carrying sludge passes through the sludge container.

[0018] The fluid passage includes at least a portion of the inlet passage formed by the connecting pipe.

[0019] As a further improvement of this utility model, the sewage inlet is open and facing upwards, and the sewage inlet channel includes an inlet end located outside the housing and an outlet end located within the first accommodating space and above the sewage inlet.

[0020] The cover includes a cover plate portion located above the outlet end and an annular portion extending downward from the cover plate portion into the interior of the sludge container.

[0038] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims.

[0040] like Figure 1 As shown in Figure 6, one embodiment of this utility model provides a cleaning device 100, which can be a wet or dry vacuum cleaner. The cleaning device 100 includes a housing 10 and a connecting pipe 20.

[0041] The housing 10 includes a housing body 11 and a cover 12 detachably connected to the housing body 11. The cover 12 and the housing body 11 enclose a first accommodating space 13. The connecting pipe 20 is used to connect the first accommodating space 13 and the outside of the housing 10, and includes a first pipe 21 connected to the housing body 11, a second pipe 22 connected to the cover 12, a first joining structure 30 disposed on the first pipe 21, and a second joining structure 40 disposed on the second pipe 22. The first joining structure 30 and the second joining structure 40 are configured to cooperate so that the first pipe 21 and the second pipe 22 can be joined together in a first direction.

[0042] First direction such as Figure 2As indicated by the arrow in -3, when the cover 12 approaches the shell body 11 along the first direction, the first joining structure 30 and the second joining structure 40 can be joined together, and the first tube 21 and the second tube 22 are arranged opposite to each other along the first direction. In this embodiment, the cover 12 is located at the top of the shell body 11, and the first direction can be understood as the height direction of the cleaning device 100.

[0043] In other embodiments, the first direction may also be the length or width direction of the cleaning device 100. That is, after the cover 12 moves closer to the shell body 11 along the length direction of the cleaning device 100, the first joining structure 30 and the second joining structure 40 can be joined together. Or, after the cover 12 moves closer to the shell body 11 along the width direction of the cleaning device 100, the first joining structure 30 and the second joining structure 40 can be joined together.

[0044] Specifically, the first accommodating space 13 has an upwardly opening, and the cover 12 is detachably connected to the shell body 11, that is, the cover 12 detachably covers the opening. The connecting tube 20 may also include a third tube 24, which is formed on the shell body 11 and extends at least partially beyond the shell body 11. The third tube 24 connects the outside of the shell 10 and the first accommodating space 13.

[0045] The first tube 21 is disposed in the first accommodating space 13 and is connected to the third tube 24. The second tube 22 is disposed below the cover 12. When the cover 12 is closed on the opening, the second tube 22 and the first tube 21 are joined together by the first joining structure 30 and the second joining structure 40, so that the third tube 24 can be connected to the first accommodating space 13 through the first tube 21 and the second tube 22.

[0046] The first joining structure 30 includes a first abutting portion 31 connected to one end of the first tube 21 near the second tube 22, and a guide portion 32 extending from the first abutting portion 31 toward the second tube 22. The second joining structure 40 includes a guide cavity 42 that cooperates with the guide portion 32, and a second abutting portion 41 that abuts against the first abutting portion 31 along a first direction.

[0047] The guide part 32 and the guide cavity 42 are configured to cooperate. It should be understood that when the guide part 32 extends into the guide cavity 42, the guide cavity 42 guides the guide part 32, so that the guide part 32 can basically only move along the axial direction of the guide cavity 42.

[0048] In this embodiment, the first abutment portion 31 and the guide portion 32 are both coaxially arranged with the first tube body 21, and the guide cavity 42 and the second abutment portion 41 are both coaxially arranged with the second tube body 22. During the process of connecting the cover 12 to the shell body 11, the guide portion 32 first extends into the guide cavity 42 along a first direction to define the relative position between the cover 12 and the shell body 11, thereby aligning the first tube body 21 and the second tube body 22. Then, the first abutment portion 31 abuts against the second abutment portion 41 along the first direction and completely fits together, ensuring a sealing effect between the first tube body 21 and the second tube body 22. With the above configuration, the cleaning device 100 of this embodiment can tolerate a larger manufacturing tolerance during manufacturing, thereby reducing production costs.

[0049] In this embodiment, in the first direction, the outer diameter of the guide portion 32 and the diameter of the guide cavity 42 remain unchanged, and the diameter of the guide cavity 42 is larger than the outer diameter of the guide portion 32. In this configuration, the diameter of the guide cavity 42 is larger than the outer diameter of the guide portion 32, resulting in a gap 70 between the guide cavity 42 and the guide portion 32. This ensures that the guide portion 32 smoothly enters the guide cavity 42 during the connection of the cover 12 to the shell body 11. Since the diameters of the guide portion 32 and the guide cavity 42 remain unchanged in the first direction, the size of the gap 70 between them also remains unchanged. Therefore, when the cover 12 and the shell body 11 move relative to each other in the first direction, the allowable relative displacement between the first tube 21 and the second tube 22 remains constant, allowing the first tube 21 and the second tube 22 to be precisely joined together.

[0050] In this embodiment, the second tube 22 and the guide portion 32 abut against each other along the first direction at the end away from the first abutting portion 31, thereby further ensuring the sealing effect between the first tube 21 and the second tube 22.

[0051] In this embodiment, a first arc surface 33 is formed on the side of the first abutting portion 31 facing the second abutting portion 41, and a second arc surface 44 is formed on the side of the second abutting portion 41 facing the first abutting portion 31 to cooperate with the first arc surface 33. When the first abutting portion 31 and the second abutting portion 41 abut against each other along the first direction, the first arc surface 33 and the second arc surface 44 come into contact. By utilizing the contact between the first arc surface 33 and the second arc surface 44, there is a sufficient contact area between the first abutting portion 31 and the second abutting portion 41, thereby ensuring the sealing effect between the first tube body 21 and the second tube body 22.

[0052] Furthermore, such as Figure 4As shown, the second joining structure 40 includes a tube body portion 45 and a connecting portion 46 connecting the tube body portion 45 and the second tube body 22. A guide cavity 42 is formed inside the tube body portion 45. The second abutment portion 41 is located on the side of the tube body portion 45 away from the connecting portion 46, and the inner diameter of the second abutment portion 41 gradually decreases in the direction approaching the tube body portion 45. With the above configuration, the second abutment portion 41 is generally shaped like a "flare". In the direction approaching the tube body portion 45, the diameter of the second arc surface 44 gradually decreases. Furthermore, the generally "flare" shape of the second abutment portion 41 also facilitates the insertion of the guide portion 32 into the guide cavity 42.

[0053] In this embodiment, the second joint structure 40 further includes a reinforcing rib 43 connected to the periphery of the tube body portion 45. The reinforcing rib 43 is arranged around the tube body portion 45 to enhance the strength of the second joint structure 40.

[0054] The second joint structure 40 is made of a flexible material with a certain degree of elasticity. After the cover 12 is connected to the shell body 11, the second abutment 41 can fully contact the first abutment 31 to ensure that the first abutment and the second abutment are completely fitted together, thereby ensuring the sealing effect between the first tube 21 and the second tube 22.

[0055] The first tube body 21 and the first connecting structure 30 are integrally formed, which ensures the connection strength between the first tube body 21 and the first connecting structure 30. Furthermore, both can be manufactured simultaneously using the same process, reducing manufacturing costs.

[0056] The second joining structure 40 can be made of thermoplastic elastomer, and it can be integrally injection molded with the second tube 22 during manufacturing. This ensures the connection strength between the second tube 22 and the second joining structure 40, and also reduces the manufacturing cost of both.

[0057] In this embodiment, a second accommodating space 14 is also formed within the housing 10, and the cleaning device 100 further includes a suction motor 50 and a waste container 60. The suction motor 50 is disposed within the second accommodating space 14 and is used to generate negative pressure to form a fluid channel that at least partially passes through the first accommodating space 13 and the second accommodating space 14 sequentially (the flow path of the fluid channel is as follows). Figure 1 (As shown in path S1). The sludge container 60 is located in the first accommodating space 13. Under the negative pressure generated by the suction motor 50, the fluid carrying dirt outside the shell 10 can enter the first accommodating space 13 and the second accommodating space 14 in sequence through the fluid channel. When the fluid carrying dirt enters the second accommodating space 14 from the first accommodating space 13, it will pass through the sludge container 60. When passing through the sludge container 60, the sludge inlet 61 of the sludge container 60 can collect the dirt.

[0058] The aforementioned connecting pipe 20 forms a sewage inlet channel 23. Fluid carrying dirt outside the shell 10 enters the first accommodating space 13 through the sewage inlet channel 23. It is conceivable that the aforementioned fluid channel at least partially includes the sewage inlet channel 23.

[0059] As described above, when the suction motor 50 is working, a negative pressure is generated in the first accommodating space 13. When the cover 12 is placed on the shell body 11, the suction motor 50 operates, and the driving force formed by the pressure difference inside and outside the first accommodating space 13 enables the cover 12 to move along the first direction to tightly cover the upward-opening opening of the first accommodating space 13. Under the action of the aforementioned driving force, the guide portion 32 extends into the guide cavity 42 along the first direction, and the first abutting portion 31 abuts against the second abutting portion 41 along the first direction.

[0060] In this embodiment, the inlet 61 is open and facing upwards. The inlet channel 23 includes an inlet end 231 located outside the housing 10 and an outlet end 232 located inside the first accommodating space 13 and above the inlet 61. The cover 12 includes a cover plate portion 121 located above the outlet end 232 and an annular portion 122 extending downwards from the cover plate portion 121 into the sludge container 60. The annular portion 122 surrounds the outlet end 232 and forms a guide channel 123 with the cover 12. The fluid channel at least partially includes the inlet channel 23 and the guide channel 123. The guide channel 123 ensures that external dirt flows into the sludge container 60 after passing through the inlet channel 23, rather than into the area outside the sludge container 60 in the first accommodating space 13.

[0061] In summary, when using the cleaning device 100 provided in this embodiment, during the process of connecting the cover 12 to the shell body 11, the guide portion 32 first extends into the guide cavity 42 along the first direction to define the relative position between the cover 12 and the shell body 11, thereby aligning the first tube 21 and the second tube 22. Then, the first abutting portion 31 abuts against the second abutting portion 41 along the first direction, ensuring a sealing effect between the first tube 21 and the second tube 22. With the above-described configuration, the cleaning device 100 of this embodiment can tolerate a larger manufacturing tolerance during manufacturing, thereby reducing production costs.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
