[0036] Surface cleaning equipment is a widely used cleaning tool that often cleans by sucking foreign matter from the surface being cleaned. Some surface cleaning equipment has an air duct through which foreign matter is sucked. This air duct may have bends, where foreign matter can be easily transported and clogged. Furthermore, because the air duct is located within the surface cleaning equipment, it is difficult to inspect the bends. Blockages in these bends are also difficult to clear.

[0037] Based on this, an embodiment of the present application provides a surface cleaning device that can solve the problem that it is difficult to view the bends in the air duct and difficult to clean the bends in the air duct when they are blocked.

[0038] Figure 1 is a schematic diagram of the structure of a surface cleaning device provided in one embodiment of the present application. Figure 2 is a schematic diagram of the structure of the portable cleaning unit of the surface cleaning device in Figure 1 after it is disassembled. Figure 3 is a schematic diagram of the partial structure of the portable cleaning unit and the second part of the surface cleaning device in Figure 1 after it is disassembled. Figure 4 is a schematic diagram of a partial cross-section of the surface cleaning device in Figure 1. Referring to Figures 1 to 4, the surface cleaning device includes: an upright portion 10, a fluid channel 100, a bent section 110, a first portion 111, a first opening 1111, a second portion 112, a portable cleaning unit 20, a floor brush 40, and a floor brush inlet 41. The floor brush 40 has a floor brush inlet 41. The upright portion 10 is rotatably mounted on the floor brush 40. The portable cleaning unit 20 is detachably mounted on the upright portion 10. The portable cleaning unit 20 has a cleaning unit inlet (not shown). A fluid channel 100 is located between the portable cleaning unit inlet (not shown) and the floor brush inlet 41. The fluid channel 100 serves as a channel for the surface cleaning device to absorb foreign matter from the surface to be cleaned. By sucking in fluid, such as air, etc., the foreign matter on the surface to be cleaned can be sucked into the surface cleaning device along with the sucked fluid. Foreign matter can include solids such as dust and debris, liquids such as water and sewage, and solid-liquid mixtures composed of the aforementioned solids and liquids. The fluid channel 100 can be formed by one of the following pipes or a combination of multiple pipes: a hose, a hard pipe, and a tubular channel of a vertical part, and a part of the pipe wall of the vertical part. The fluid channel 100 includes at least one bent section 110. The bent section 110 can be the part of the fluid channel where the suction direction changes when the fluid channel 100 absorbs foreign matter. Since the suction direction changes when sucking foreign matter, the tube wall of the fluid channel 100 here may produce some resistance to the suction of foreign matter and easily change the direction of travel of foreign matter relative to the fluid channel 100. Therefore, the fluid channel 100 is prone to blockage, foreign matter adhesion, foreign matter stuck in the tube and other abnormal conditions in the bending section 110, resulting in a decrease in the suction force of the surface cleaning equipment, reduced cleaning efficiency and cleaning effect, resulting in reduced performance of the surface cleaning equipment, and affecting the user experience.

[0039] To facilitate inspection of the interior of the bending section 110 and facilitate prompt cleaning of the interior of the bending section 110 in the event of blockage, foreign matter adhesion, or pipe jamming, the bending section 110 of this embodiment includes a detachably connected first portion 111 and a second portion 112. The first portion 111 is provided with a first opening 1111, and the second portion 112 detachably seals the first opening 1111. When the surface cleaning device is in operation, the second portion 112 seals the first opening 1111, and the bending section 110 functions normally as a fluid passageway 100. To inspect the interior of the bending section 110 for blockage, foreign matter adhesion, accumulation, or pipe jamming, or to perform regular or irregular inspection and cleaning of the bending section 110, or to detect any of the aforementioned abnormalities within the bending section 110 and require cleaning, the second portion 112 can be removed from the first opening 1111, exposing the interior of the bending section 110 for subsequent inspection or cleaning.

[0040] The second part is any object that can be detachably connected to the first part and seal the first opening. In some embodiments, the second part can be completely separated from the first part after being removed from the first opening. Exemplarily, the second part is a standalone component that can be removed from the surface cleaning device, providing more space for inspection, cleaning, and other operations. Exemplarily, the second part is configured as a tear-off tape. The area of ​​the tear-off tape is larger than the first opening. When the surface cleaning device is in operation, the tear-off tape is affixed to the first opening, sealing the first opening. When it is necessary to inspect the interior of the bent section, the tear-off tape is removed, and the interior of the bent section is directly exposed for subsequent inspection or cleaning operations. Exemplarily, the second part can also be configured as an elastomer with a suction cup, the suction cup being disposed on one side of the elastomer sealing the first opening. The area enclosed by the suction cup is larger than the first opening. When the elastomer seals the first opening, the suction cup adheres to the first part and circles the first opening at least once to seal the first opening. When the surface cleaning device is in operation, the elastomer adheres to the first opening, sealing the first opening. When it is necessary to check the internal situation of the bending section, the elastic body is removed and the interior of the bending section can be directly exposed for subsequent inspection or cleaning operations.

[0041] In some embodiments, the second portion can be partially connected to the first portion after being removed from the first opening. For example, the edge of the second portion is rotatably connected to the first portion. For example, the rotatable connection can be achieved by the cooperation of a shaft, a sleeve, etc., or by connecting the two materials. The specific structure of the rotatable connection can be set according to actual needs. For example, the rotatable connection can be achieved by the cooperation of a shaft, a sleeve, etc., or by connecting the two materials. The specific structure of the rotatable connection can be set according to actual needs.

[0042] The shape of the second portion can be customized based on actual needs. For example, the second portion can be composed of an arc plate or a flat plate. For example, when the second portion closes the first opening, the cross-section of the channel formed by the second portion and the first portion can be a regular shape such as a circle or an ellipse, or an irregular shape composed of straight lines and arcs.

[0043] As shown in FIG2 , the surface cleaning device of this embodiment includes a portable cleaning unit 20. The portable cleaning unit 20 is detachably connected to the upright portion 10 and can be removed from the surface cleaning device to expose the bent section 110. In some embodiments, the bent section of the fluid channel can be directly exposed, thus eliminating the need to remove the portable cleaning unit to expose the bent section.

[0044] As shown in Figure 4 , the surface cleaning device in this embodiment includes a floor brush 40. Floor brush 40 can be used to collect foreign matter into a floor brush inlet 41 (also referred to as the suction port of the surface cleaning device), thereby cleaning the surface to be cleaned. A fluid channel 100 is provided between the inlet of the portable cleaning unit (not shown) and the floor brush inlet 41. In some embodiments, the surface cleaning device may not include a floor brush or other structure, and the fluid channel may be provided directly between the suction port of the surface cleaning device and the cleaning unit inlet.

[0045] The fluid channel of the surface cleaning device of the present application includes at least one bending section, wherein at least one bending section includes a first part and a second part that are detachably connected, the first part is provided with a first opening, and the second part detachably closes the first opening. When it is necessary to check the internal conditions of the bending section, such as whether there are abnormal conditions such as blockage, foreign matter attachment, accumulation or jamming, or to clean the bending section regularly or irregularly, or when the above-mentioned abnormal conditions exist inside the bending section and need to be cleaned, the second part can be removed from the first opening to directly expose the inside of the bending section for the above-mentioned operations, so that the above-mentioned abnormal conditions can be discovered and handled in a timely manner, thereby avoiding the decrease in the suction power of the surface cleaning device, ensuring the cleaning efficiency and cleaning effect of the surface cleaning device, and ensuring the performance of the surface cleaning device. In addition, the exposure of the inside of the bending section of the fluid channel is achieved simply by removing the second part from the bending section, which is extremely convenient and improves the user experience.

[0046] 1 to 3 , in some embodiments, the second portion 112 is configured as a cover 1124 , and the first opening 1111 is configured to be covered from above by the cover 1124 . The cover 1124 covers the first opening 1111 , thereby sealing the first opening 1111 .

[0047] As shown in Figure 3, after the cover body 1124 is disassembled at the first opening, it can be completely separated from the first part 111 and removed from the surface cleaning equipment, leaving more space for inspection, cleaning and other operations. In some embodiments, the cover body can also be partially connected to the first part after being disassembled at the first opening. Exemplarily, the edge of the cover body is rotatably connected to the first part. For example, the rotatable connection can be achieved by the cooperation of a shaft, a sleeve, etc., or by the connection of the materials of the two. The specific structure of the rotatable connection can be set according to actual needs. For example, the rotatable connection can be achieved by the cooperation of a shaft, a sleeve, etc., or by the connection of the materials of the two. The specific structure of the rotatable connection can be set according to actual needs.

[0048] The shape of the cover can be customized based on actual needs. For example, the cover can be composed of an arc plate or a flat plate. For example, when the second portion closes the first opening, the cross-section of the channel formed by the second portion and the first portion can be a regular shape, such as a circle or an ellipse, or an irregular shape composed of straight lines and arcs.

[0049] By configuring the second portion as a cover, the first opening can be closed or opened by simply closing or opening the cover, thereby exposing the interior of the bent section of the fluid channel. This improves the convenience of this operation and further enhances the user experience. Since surface cleaning equipment often has more operating space at the top, configuring the first opening to be covered by the cover from above facilitates the user's opening and closing operation of the cover from above, thereby improving the user experience. In addition, configuring the first opening to be covered by the cover from above makes it easier to point the first opening upward or diagonally upward.

[0050] In some embodiments, the first opening faces upward or obliquely upward. The first opening of the first part faces upward or obliquely upward, so that the interior of the bending section is exposed upward or obliquely upward, which is visually more convenient for the user to view the interior of the bending section. In addition, since other components of the surface cleaning equipment are often not provided above or obliquely above the bending section, or the components above or obliquely above the bending section are more convenient to be disassembled to expose the bending section, there is often more operating space above or obliquely above the bending section, or the user is less likely to be restricted during operation. Therefore, such a setting is more convenient for covering or disassembling the cover body, and cleaning the interior of the bending section, which greatly improves the user experience. In some embodiments, the first opening can also face sideways. The specific situation of the first opening can be set according to the specific structure of the surface cleaning equipment and the method of use.

[0051] As shown in Reference 4 , in some embodiments, the bending section 110 includes a first bending section opening 113 and a second bending section opening 114 located at both ends, respectively. The first portion 111 is further provided with a second opening 1119. The second opening 1119 forms the first bending section opening 113 and is configured to be in fluid communication with the floor brush inlet 41. This arrangement allows foreign matter sucked in through the floor brush inlet 41 to enter the first portion 111 of the bending section 110 through the first bending section opening 113, i.e., the second opening 1119, and then pass through the second bending section opening 114 into the pipeline or device connected to the second bending section opening 114.

[0052] As shown in Reference 4, in some embodiments, the cover 1124 has a cover opening 1120, which forms the second bend section opening 114 and is configured to be fluidically connected to the second bend section opening 114 through the pipe member 30 when the portable cleaning unit 20 is assembled on the upright portion 10. For example, the pipe member 30 can be a hose or a hard pipe. For example, the portable cleaning unit 20 includes a foreign matter collection device (not shown in the figure), and the pipe member 30 is disposed in the portable cleaning unit 20 and fluidically connected to the foreign matter collection device (not shown in the figure) in the portable cleaning unit 20 to collect foreign matter. For example, as shown in Figure 4, the pipe member 30 is detachably connected to the cover 1124 at the second bend section opening 114 (or the cover opening 1120). When the cover 1124 needs to be removed from the first opening, it can also be removed from the pipe member 30. As an implementation, when the cover 1124 needs to be removed from the first opening 1111, the pipe member 30 is first removed, and then the cover 1124 is removed. For example, the pipe member and the cover can be fixedly connected. When the cover needs to be removed from the first opening, the pipe member and the cover can be removed simultaneously to leave their original positions. In some embodiments, as shown in FIG3 , the cover opening 1120 is tubular in shape.

[0053] By providing a cover body with a cover body opening, the cover body opening forms a second bending section opening. When the portable cleaning unit is assembled on the upright portion, the fluid is connected to the second bending section opening through the pipe part, and foreign matter can enter the pipe part through the cover body opening of the cover body, that is, the cover body not only serves as part of the pipe wall of the fluid channel, but also as part of the pipe section of the fluid channel. When the cover body needs to be disassembled at the first opening, the part of the pipe section of the fluid channel served by the cover body is exposed due to being disassembled, and the interior of the bending section with the cover body is also exposed. Therefore, more interiors of the pipes in the fluid channel are exposed, which is conducive to better viewing and cleaning of the bending section, and improves the processing efficiency when abnormal situations such as blockage of the bending section occur. In addition, this embodiment also provides a composition scheme for the fluid channel, which is conducive to making the fluid channel adaptable to surface cleaning equipment with more complex structures.

[0054] Referring to Figure 4, in some embodiments, the first part 111 is located at the bottom end of the upright part 10 and is integrally formed with the upright part 10. The first part 111 is provided at the bottom end of the upright part 10, that is, the bending section 110 is located at the bottom end of the upright part 10 or near the bottom end. The fluid channel 100 at the bottom end of the upright part 10 is often connected to components such as the floor brush 40 and the suction head (not shown in the figure), so that the fluid channel 100 here has a more complex bending design. Therefore, the fluid channel 100 located at the bottom end of the upright part 10 or near the bottom end is more prone to abnormal conditions such as blockage and foreign matter adhesion. The first part involved in any embodiment of the present application is provided at the bottom end of the upright part, so that the internal situation of the first part can be exposed by removing the cover body from the first opening, so that the structure of the bending section has stronger practicality and utilization, thereby improving the user experience.

[0055] The first part 111 and the upright part 10 are formed as one piece. On the one hand, this avoids the assembly of the first part and the upright part, reducing the complexity of assembling the surface cleaning equipment; on the other hand, it avoids the joints generated when assembling the first part and the upright part, which helps to ensure the suction and cleaning effect of the surface cleaning equipment.

[0056] 3 , in some embodiments, the bottom end of the upright portion 10 has a groove 120, and the bent section 110 is received in the groove 120, so that the bent section is not visible when the portable cleaning unit 20 is assembled on the upright portion 10. Exemplarily, the portable cleaning unit 20 is detachably connected to the upright portion 10 at the groove 120, and the portable cleaning unit 20 can cover the groove 120 that receives the bent section 110, so that the bent section is not visible when the portable cleaning unit 20 is assembled on the upright portion 10. The bent section 110 can be exposed by removing the portable cleaning unit 20 at the groove 120. This arrangement can hide the fluid channel structure, making the surface cleaning device more beautiful. On the other hand, the upright portion and the portable cleaning unit assembled outside the fluid channel can protect the fluid channel from dangerous factors such as bumps, and can also increase the sealing performance of the surface cleaning device.

[0057] As shown in FIG3 , in some embodiments, the first portion 111 is integrally formed with the groove 120, and the second portion 112 is received within the groove 120 when connected to the first portion 111. Directly integrating the first portion 111 with the groove 120 that accommodates the bent section 110 helps reduce the volume of the upright portion, simplifies the design of the upright portion, and facilitates the manufacture and assembly of the surface cleaning device. Receiving the second portion 112 within the groove 120 when connected to the first portion 111, as an implementation method, reduces the volume of the bent section, which helps to reduce the weight of the surface cleaning device.

[0058] Figure 5 is a partial cross-sectional schematic diagram of a bending section provided in one embodiment of the present application. Figure 6 is a top view of the bending section in Figure 5. Figure 7 is a partial cross-sectional schematic diagram of a bending section provided in another embodiment of the present application. Figure 8 is a top view of the bending section in Figure 7.

[0059] In some embodiments, as shown in Figures 5 and 7 , the first portion 111 includes a first straight section 1112, a first curved section 1113, and a second straight section 1114, which are sequentially connected. The straight section of the first portion corresponds to the straight section of the bent section, and the curved section of the first portion corresponds to the curved section of the bent section. In other words, the bent section may include a curved section. In some embodiments, as shown in Figures 5 and 6 , the first opening 1111 may be provided in both the first straight section 1112 and the first curved section 1113. In some embodiments, as shown in Figures 7 and 8 , the first opening 1111 may also be provided in both the first curved section 1113 and the second straight section 1114. In some embodiments, the first opening may be provided only in the first curved section. For example, if the first curved section is long, providing the first opening only in the first curved section allows for inspection and cleaning of easily clogged areas. In some embodiments, the first opening may be provided in all three sections: the first straight section, the first curved section, and the second straight section. In some embodiments, the first curved section may have multiple curvatures. In some embodiments, the cover body needs to be detachably covered on the larger first opening. In order to ensure the strength of the cover body, the cover body can be composed of multiple sub-cover bodies. The above embodiments provide a variety of ways to set the first opening and the cover body in the bending section. By detachably covering the cover body on the first opening, the bending section can be inspected and cleaned. The specific implementation method of the first opening and the cover body can be set according to the specific structure and usage method of the surface cleaning equipment to more reasonably enhance the user experience. For example, as shown in Figures 5 and 6, the first opening 1111 is provided in the first straight section 1112 and the first curved section 1113, so that the first opening is configured to be covered by the cover body from above, and the first opening is oriented upward, which improves the convenience for the user to inspect and clean the bending section.

[0060] Figure 9 is a partial cross-sectional view of a bending section provided in another embodiment of the present application. Figure 10 is a top view of the bending section in Figure 9 .

[0061] In some embodiments, as shown in Figures 9 and 10, in addition to the first straight section 1112, the first curved section 1113, and the second straight section 1114 connected in sequence, the first portion 111 also includes a third straight section 1115 and a second curved section 1116 connected in sequence, with the second curved section 1116 connected to the first straight section 1112. The first opening 1111 is provided in the second curved section 1116, the first straight section 1112, and the first curved section 1113. In other words, the bending section may include multiple curved sections. When the bending section includes multiple curved sections, the bending section is more prone to abnormalities such as blockage. When the bending section includes two curved sections connected by a straight section, the first opening can be provided in the two curved sections and the straight section connecting the two curved sections.

[0062] By setting the first opening at the second curved section, the first straight section and the first curved section, and detachably covering the first opening with a cover body, when the cover body is removed from the first opening, the second curved section, the first straight section and the first curved section can be directly exposed, so that the two curved sections and the straight section between the two curved sections, that is, the pipe sections that are prone to abnormal conditions such as blockage, can be checked and cleaned at the same time, thereby improving the efficiency of handling abnormal conditions such as blockage in the fluid channel and enhancing the user experience.

[0063] In some embodiments, as shown in FIG4 , the first straight section 1112 extends in the horizontal direction (the X direction as shown in FIG4 ), and the second straight section 1114 extends in the vertical direction (the Y direction as shown in FIG4 ). When the surface cleaning device is at rest after work, foreign matter that has not been collected by the foreign matter collection device (not shown in the figure) is more likely to adhere to or accumulate in the first straight section extending in the horizontal direction. In some embodiments, the second straight section can also extend in other non-horizontal directions such as the vertical direction. When the first straight section is extended in the horizontal direction, the first opening is provided in the second curved section, the first straight section and the first curved section, or the first opening is provided in the first straight section and the first curved section. After the cover is removed at the first opening, the interior of the first straight section is exposed, which can further improve the practicality and utilization rate of this structure and enhance the user experience.

[0064] In some embodiments, the second portion is made of a transparent material. Transparent materials include any material that allows the object behind the cover to be seen through the cover, such as transparent plastic, transparent glass, etc. By making the second portion of the material transparent, the user does not need to disassemble the second portion. Instead, when the bent section where the second portion is located is exposed, the user can directly observe the bent section and see the interior of the bent section through the second portion. This simplifies the process of viewing the interior of the bent section and improves the user experience. As can be seen from the above embodiments, the cover can be made of a transparent material.

[0065] In some embodiments, a detachable structure is provided between the first portion and the second portion (or cover), allowing the second portion (or cover) to be removed from the first opening of the first portion. In some embodiments, the second portion (or cover) is a separate component that can be removed from the surface cleaning device. For example, as shown in FIG3 , the first portion 111 has a slot 1117, and the edge of the second portion 112 (or cover 1124) includes a latch 1121 that engages with the slot 1117. By pinching the edge of latch 1121, latch 1121 separates from the slot 1117, allowing the second portion 112 (or cover 1124) to be removed from the first opening 1111. A pair of latches 1121 is positioned correspondingly to the slot 1117. Multiple pairs of latches and slots may also be provided between the first and second portions (or covers). In some embodiments, as mentioned above, a portion of the edge of the second portion (or cover) is rotatably connected to the first portion, allowing the second portion (or cover) to be removed from the first opening by lifting the second portion (or cover). For example, the rotatable connection can be achieved by mating a shaft, sleeve, or the like, or by connecting the two materials.

[0066] In some embodiments, a limiting structure is provided between the first portion and the second portion (or the cover). For example, as shown in FIG3 , the first portion 111 has a limiting groove 1118, and the second portion 112 (or the cover 1124) includes a limiting protrusion 1122. The limiting protrusion 1122 cooperates with the limiting groove 1118 to limit the position of the second portion 112 (or the cover 1124). A pair of limiting protrusions 1122 and limiting grooves 1118 are positioned correspondingly. Multiple pairs of limiting protrusions 1122 and limiting grooves 1118 can be provided.

[0067] In some embodiments, the surface cleaning device further comprises a sealing structure disposed between the first portion and the second portion (or the cover). Exemplarily, a sealing gasket is disposed at the edge of the first portion and / or the second portion 112 (or the cover 1124), and the sealing gasket is squeezed by the pressure generated when the first and second portions 112 (or the cover 1124) are assembled to achieve sealing. Exemplarily, the sealing gasket may be disposed at the first opening of the first portion. In some embodiments, an elastic ring is disposed at the edge of the first portion and / or the second portion (or the cover) for sealing. Exemplarily, an elastic ring is disposed at the first opening of the curved segment body, and when the second portion (or the cover) closes the first opening, the outer edge of the second portion (or the cover) is wrapped by the elastic ring, thereby achieving sealing between the first and second portions (or the cover).

[0068] In some embodiments, a sealing structure is further disposed between the pipe member and the second bending section opening (or the cover opening). The sealing structures described in the above embodiments can all be used between the pipe member and the second bending section opening (or the cover opening). For example, as shown in Figures 3 and 4 , a sealing sleeve 1123 is disposed outside the second bending section opening 114 (or the cover opening 1120). The sealing sleeve 1123 is sleeved around the second bending section opening 114 (or the cover opening 1120). The pipe member 30 is deformed by squeezing the sealing sleeve 1123, thereby achieving a seal between the pipe member and the second bending section opening (or the cover opening).
