Users operate the machine by gripping a handle on the main body to clean the surface. However, the working head and main body of existing cleaning machines are fixedly connected, making it impossible to adjust the angle of the working head relative to the main body. This makes it difficult for users to conveniently clean glass and tile surfaces in different spatial locations. Therefore, a solution to this problem is necessary. Summary of the Invention

Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0018] Figure 1 FIG. 1 is a plan view of a rotary cleaning machine according to an embodiment of the present invention. DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, an embodiment of the present invention provides a rotary cleaning machine, which includes: a working head 1, a body 2, a liquid collecting mechanism 3, a negative pressure mechanism 4 and a power supply circuit 5.

[0021] The working head 1 is used to achieve surface cleaning. In order to facilitate flexible cleaning of surfaces in different spatial orientations, the working head 1 is designed to be able to rotate 360° to adjust the cleaning angle as needed, thereby facilitating operations during cleaning.

[0022] Specifically, a flexible scraping element 11 is mounted on one end of the working head 1, and the other end is pivotally connected to the body 2. The flexible scraping element 11 is a sponge or rubber strip with an edge extending from the end of the working head 1, and performs a cleaning function by scraping against the surface being cleaned.

[0023] The body 2 is provided with an assembly cavity 21 for facilitating the pivotal connection of the other end of the working head 1. The other end of the working head 1 is inserted into the assembly cavity 21 with an interference fit. In this way, while ensuring that it can rotate 360°, it also has a certain pivoting retention force to maintain the working head 1 at the required angular position. Accordingly, a rubber ring 12 is provided between the other end of the working head 1 and the assembly cavity 21. The rubber ring 12 is fitted on the other end of the working head 1 and deforms under a certain pressure. In one embodiment, the rubber ring 12 is fitted on both ends of the portion of the working head 1 accommodated in the assembly cavity 21, and the portion of the working head 1 between the rubber rings 12 does not contact the interior of the assembly cavity 21 to avoid excessive damping force that is not conducive to the rotation of the working head 1.

[0024] Since it is usually necessary to scrape the surface with a cleaning liquid when cleaning the surface, in order to prevent the cleaning liquid from flowing out, the working head 1 also has a water absorption function.

[0025] Specifically, the working head 1 is hollow within its interior. While its other end is pivotally connected to the body 2, it also maintains communication with the body 2. This allows the negative pressure created within the body 2 by the negative pressure mechanism 4 to recover external cleaning fluid into a specific space for storage. Accordingly, the working head 1 has a liquid inlet at one end, where the flexible scraping element 11 is mounted, and a liquid outlet at the other end. The bottom of the assembly cavity 21 has an opening that communicates with the interior. External cleaning fluid flows through the liquid inlet, through the internal space of the working head 1, and then through the liquid outlet into the aforementioned specific space.

[0026] The specific space may be an independent space formed in the body 2 or a collection bottle provided separately from the body 2 .

[0027] When the specific space is an independent space within the housing 2, it remains isolated from the rest of the housing 2, and the opening at the bottom of the assembly cavity 21 directly communicates with the independent space. In this case, the other end of the working head 1 can be connected to the independent space via a liquid collection mechanism 3, which may or may not extend into the independent space. Furthermore, the independent space also has a drainage hole.

[0028] When the specific space is a collection bottle 6 that is separate from the body 2, the collection bottle 6 is detachably mounted on the body 2. At this time, the other end of the working head 1 can be connected to the collection bottle 6 via the liquid collection mechanism 3. The liquid collection mechanism 3 can be inserted into or not inserted into the collection bottle 6. When drainage is required, the collection bottle 6 can be removed and the cleaning liquid therein can be poured out.

[0029] The negative pressure mechanism 4 is used to form a negative pressure environment inside the body 2 so that the working head 1 can simultaneously absorb and recover the cleaning liquid during cleaning.

[0030] Specifically, the negative pressure mechanism 4 includes a fan blade 41 and a power unit 42 that drives the fan blade 41. The negative pressure mechanism 4 is installed in a separate assembly space 22 within the fuselage 2. The assembly space 22 has an air intake 221, and the fan blade 41 is positioned adjacent to and facing away from the air intake 221. As the power unit 42 rotates the fan blade 41, the fan blade 41 continuously draws air through the air intake 221, creating a negative pressure environment in the specific water storage space. In one embodiment, the power unit 42 is a motor.

[0031] The liquid collecting mechanism 3 is used to separate the sucked-in cleaning liquid and air so that the cleaning liquid can be recovered independently and the air can be sucked independently through the negative pressure mechanism 4 .

[0032] The principle is that all substances have a suspension velocity, so at a preset water absorption cross-section, the air velocity within the interface can reach the suspension velocity, thereby absorbing water. At the same time, increasing the cross-sectional area at a preset location can reduce the air velocity, making it much lower than the suspension velocity of liquids such as water. Furthermore, liquids retain their initial inertial velocity and are not easily changed, thus achieving a natural separation of liquid and gas. Water absorption can be achieved even when tilted or inverted.

[0033] Specifically, the liquid collection mechanism 3 includes: a separation body 31, a gas-liquid channel 32 provided through the separation body 31, and a gas suction channel 33. The gas-liquid channel 32 is provided independently of the gas suction channel 33. One end of the gas-liquid channel 32 is connected to the opening at the bottom of the assembly cavity 21 through the suction channel, and the other end is connected to the specific space where water is stored. The air inlet end of the gas suction channel 33 extends to the other end of the gas-liquid channel 32, and the air outlet end extends to the air outlet 221. In this way, after the gas-liquid mixture enters through the gas-liquid channel 32, the cleaning liquid enters the specific space where water is stored due to gravity, while the air is separated from the cleaning liquid through the gas suction channel 33 due to the negative pressure.

[0034] The power supply circuit 5 is used to power the negative pressure mechanism 4. Specifically, the power supply circuit 5 includes a battery 51, a wire 52, and a control switch 53. The battery 51 can be built into the assembly space 22 and electrically connected to the motor via the wire 52. The control switch 53 is connected in series to the wire 52 between the motor and the battery 51. The control switch 53 extends from the assembly space 22, allowing the user to control the motor's operation and deactivation.

[0035] In summary, the rotary cleaning machine of the present invention features a working head that freely rotates relative to the main body. This allows the working angle of the working head to be adjusted according to actual needs, enabling the user to clean surfaces at different locations. Furthermore, the rotary cleaning machine of the present invention can simultaneously recover cleaning liquid, preventing it from leaking out. Furthermore, by employing a liquid collection mechanism, water can be drawn in from a lower position, enabling the machine to achieve an inverted cleaning and water absorption effect.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of 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 implementation methods that can be understood by those skilled in the art.
