[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] refer to Figure 1 and 2 The figure discloses a surface cleaning device 100, which can be a handheld vacuum cleaner (connected to a cleaning head 10 via a connecting rod), an upright vacuum cleaner (such as...), or a... Figure 2 The floor scrubber shown) or self-cleaning equipment (such as...) Figure 1 (The shown is a robotic vacuum cleaner). When the surface cleaning device 100 is an autonomous cleaning device, the cleaning head 10 can be installed inside the main body 20 of the device. When the surface cleaning device 100 is a vertical cleaning device, the cleaning head 10 can be rotatably installed below the main body 20 to clean the surface to be cleaned.

[0025] refer to Figure 2-11The figure discloses a cleaning head 10, which includes a housing 1 and a cleaning component 4. The housing 1 can be composed of an upper outer shell 11 and a lower outer shell 12. Of course, in other embodiments, the housing 1 can also be composed of multiple components. The housing 1 defines a receiving space 16 and a first cavity 19. The receiving space 16 can be formed by the bottom wall 13, side wall 14 and top wall 15 of the housing 1. The receiving space 16 accommodates at least one functional element. The functional element can be one or more components such as a water pump, a steam generator or an electrolytic water structure, etc., which are just examples and are not limited to the types of components. In order to prevent the component from failing due to the presence of liquid during equipment operation or cleaning, a sealing structure 3 is provided around the functional element. The sealing structure 3 is used to seal the functional element within the receiving space 16. The sealing structure 3 can be a sealed space made of rigid material. The sealing structure 3 can also be a sealed space made of flexible material. In this way, even if liquid enters the receiving space 16, it will not enter the interior of the sealed space and will not affect the normal operation of the functional element. The cleaning component 4 is disposed within the first cavity 19 and is used to clean the surface to be cleaned. The cleaning component 4 can be a brush roller, a cloth, or other form of wiping component; no limitation is made here. To improve cleaning efficiency, the cleaning head 10 is also provided with a supply line for supplying cleaning fluid to the cleaning component 4 or the surface to be cleaned. The surface cleaning device 100 also includes a cleaning fluid tank 6 (see reference). Figure 3 The cleaning fluid tank 6 can be mounted on the cleaning head 10 or on the main body 20. At least one functional element includes a cleaning fluid pump 21, which supplies cleaning fluid from the cleaning fluid tank 6 to the cleaning element 4 or the surface to be cleaned via a supply line. When the surface cleaning device 100 is in operation, the cleaning head 10 moves over the surface to be cleaned, cleaning the surface via the cleaning element 4.

[0026] When users clean the cleaning head 10, some users rinse it with a tap, while others soak it in the mop sink. This causes liquid to enter the receiving space 16. To facilitate the rapid drainage of this liquid, at least one first through hole 18 is provided on the bottom wall 13 of the housing 1 (see reference). Figure 2Liquid entering the accommodating space 16 or liquid generated within the accommodating space 16 (e.g., liquid generated after condensation from the heating device) can flow out of the accommodating space 16 through the first through hole 18. With this configuration, even if the cleaning head 10 is rinsed or soaked with water, the normal operation of the functional components can be guaranteed. The first through hole 18 can also be provided with a one-way structure, configured to allow only liquid within the accommodating space to flow out, while preventing liquid outside the accommodating space from entering the accommodating space. In other embodiments, at least a portion of the first through hole 18 opens to the side rather than directly towards the surface to be cleaned, thus preventing liquid outside the accommodating space from rapidly entering through the first through hole.

[0027] refer to Figure 5 and 11 The housing 1 also defines a second cavity 17. The accommodating space 16 and the second cavity 17 are separated by a side wall 14 of the housing 1. The accommodating space 16 and the second cavity 17 are not in communication. The second cavity 17 can be a separate cavity and not used to store any structure. Because the second cavity 17 is not in communication with the accommodating space 16, dirt can be prevented from entering the interior, and the presence of the second cavity 17 can reduce the volume of the accommodating space 16.

[0028] refer to Figure 9-11 The bottom wall 13 is also provided with at least one second through hole 161 communicating with the second cavity 17. In this way, even if liquid enters the second cavity 17 during cleaning, the liquid in the second cavity 17 can be quickly discharged.

[0029] Continue to refer to Figure 9-11 The top wall 15 also has at least one third through hole 162 that is in fluid communication with the second cavity 17. After the fluid enters the second cavity 17 through the third through hole 162, it can flow out through the second through hole 161. (Continue to refer to...) Figure 11 The opening areas of the second through hole 161 and the third through hole 162 are basically the same. The total area of ​​the second through hole 161 is much larger than the total area of ​​the first through hole 18. As shown in the embodiment, the area of ​​the second through hole 161 or the third through hole 162 is greater than one-third of the area of ​​the entire cleaning head 10. In this way, the area occupied by the accommodating space 16 can be minimized, and the amount of dirt inside is also reduced accordingly, making it more convenient for the user to clean.

[0030] Continue to refer to Figure 6 At least a portion of the accommodating space 16 is located on the outer periphery of the second cavity 17. The second cavity 17 can also be used to accommodate a portion of the recovery tank and / or cleaning fluid tank 6. To make the structure more compact, at least a portion of the recovery tank and / or cleaning fluid tank 6 can be installed into the second cavity 17 through the third through hole 162.

[0031] refer to Figure 5-11The surface cleaning device 100 also includes a suction channel 7 in fluid communication with the first chamber 19, at least a portion of which is located within the second chamber 17. (Reference) Figure 10 The suction channel 7 extends through the second cavity 17, which makes it easy to clean the outside of the suction channel 7.

[0032] As shown in the embodiment, the area of ​​the cleaning fluid tank 6 is larger than the area of ​​the third through hole 162. That is, the surface of the cleaning fluid tank 6 can cover the entire third through hole 162, thus making the whole thing more aesthetically pleasing.

[0033] Continue to refer to Figure 3-11 In particular, in 9-11, the housing 1 includes an upper outer shell 11 and a lower outer shell 12. The upper outer shell 11 is detachably mounted to the lower outer shell 12, making it convenient for the user to clean the interior of the accommodating space 16. The suction channel 7 can also be defined by the upper outer shell 11 and the lower outer shell 12. When the suction channel 7 needs to be cleaned, the upper outer shell 11 and the lower outer shell 12 can be disassembled to clean the interior of the suction channel 7.

[0034] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
