[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a surface cleaning device. Background Technology

[0002] Surface cleaning equipment is widely used in daily life and industrial applications to clean various surfaces, especially glass windows. For example, modern window cleaning equipment typically includes a squeegee to remove cleaning agents or water from the window surface, and then a suction head draws the water and any adhering liquid into the equipment. In existing technology, most surface cleaning equipment works by using a motor to generate negative pressure, with the suction head drawing in water through its inlet, and the liquid flowing through a channel into a storage tank.

[0003] However, existing equipment suffers from the problem of uneven fluid flow, meaning the speed of liquid suction is limited by the internal channel structure. Specifically, during the process of fluid entering the storage tank from the suction head, if the flow channel design is unreasonable or has too many bends, the liquid may not flow smoothly, resulting in excessive flow time, which affects the dewatering efficiency and further weakens the cleaning performance. This is a prominent problem in the prior art and also the technical challenge that this invention aims to solve. Summary of the Invention

Detailed Implementation

[0034] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0035] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0036] One embodiment of this utility model provides a surface cleaning device that improves water removal efficiency and cleaning performance by optimizing the flow channel design.

[0037] The surface cleaning device in this embodiment can be used for window cleaning; that is, the surface cleaning device can be a window scraper.

[0038] In use, the user places the device tightly against the window glass. The motor 30 drives the device to draw in the water adhering to the glass through the nozzle. The liquid and air are drawn into the surface cleaning device 100 together, and after gas-liquid separation, the liquid is retained inside the surface cleaning device 100, while the gas is discharged.

[0039] The surface cleaning device 100 in this embodiment is as follows: Figure 1 As shown, it includes a suction head 20, a housing 10, a motor 30, and a liquid storage tank 40. The suction head 20 has an inlet 21 and an outlet 24, and a suction head flow channel 22 is formed between the inlet 21 and the outlet 24 to draw moisture and impurities from the surface to be cleaned.

[0040] The housing 10 has an air outlet 11, and a connecting channel is formed between the inlet 21 and the air outlet 11. The motor 30 is used to generate negative pressure, and through continuous suction, the liquid forms a stable flow in the connecting channel.

[0041] The liquid storage tank 40 is at least partially located in the communication channel for collecting liquid in the communication channel.

[0042] The surface cleaning device 100 of this embodiment also includes a first fixing member 50 and a second fixing member 60. Both the first fixing member 50 and the second fixing member 60 are disposed within the housing 10 and together form the receiving cavity of the motor 30. The first fixing member 50 and the second fixing member 60 ensure that the motor 30 is securely installed and operates stably, avoiding displacement or loosening of the motor 30 during operation.

[0043] like Figure 1 As shown, the fluid intake direction in inlet 21 and the output direction in outlet 24 are both set along the first direction L1. The first fixing member 50 includes a connector and an inner flow channel 51. The suction head 20 is inserted into the connector, and the outlet 24 faces the inner flow channel 51. The inner flow channel 51 extends in a straight line along the second direction L2. The first direction L1 and the second direction L2 form an inclined angle. The inner flow channel 51 is connected to the liquid storage tank 40. This ensures that the path of the mixed fluid from the suction head 20 to the liquid storage tank 40 is as straight as possible, reducing the resistance that may be generated during the flow.

[0044] More specifically, after the fluid enters the inner flow channel 51 through the outlet 24, it flows in a straight line until it flows into the storage tank 40. During its journey from the inlet 21 to the storage tank 40, the fluid only changes direction once at the junction of the inner flow channel 51 and the outlet 24. This reduces the resistance that might be caused by excessive bends in the fluid flow, ensuring that the fluid can flow quickly and smoothly into the storage tank 40, avoiding fluid stagnation, and greatly improving fluid flow efficiency and cleaning effect.

[0045] To clearly illustrate the positions and directions described in this embodiment, reference can be made to... Figure 1As shown, the second direction L2 is defined as the vertically downward direction, and the first direction L1 is defined as the inclined direction to the lower right.

[0046] The liquid storage tank 40 is located below the suction head 20 and the motor 30. Under the suction force generated by the motor, the mixed fluid of water and air can flow along the inner flow channel 51 to the liquid storage tank 40. Then the liquid remains in the liquid storage tank 40, and the separated gas is discharged upward through the gas outlet channel.

[0047] Furthermore, in this embodiment, the fluid intake direction in the inlet 21 and the output direction in the outlet 24 are both along the first direction L1. However, it is not excluded that the fluid may have other flow directions within the suction head 20, such as... Figure 2 As shown in the structure of the suction head 20, the suction head 20 has a flat and elongated structure. The length of the inlet 21 of the suction head 20 is longer than the length of the outlet 24. During the process of the fluid flowing from the inlet 21 to the outlet 24, the fluid on both sides of the inlet 21 converges towards the middle and flows to the outlet 24 at the lower right. That is, although the main direction of the fluid flows along the first direction L1, during the flow process, some fluid can have a flow component in the front and back directions.

[0048] For the suction head 20, whose inlet 21 length is equal to the outlet 24 length, for example, if the suction head channel 22 is cylindrical or square, the flow can also be completely along the first direction L1 inside the suction head 20.

[0049] Furthermore, the housing 10 includes a first housing 101 and a second housing, which together surround and protect the working components inside the device. Figure 1 The second shell on the rear side is shown in the image. Figure 5 and Figure 7 The first shell 101 on the front side is shown in the figure.

[0050] A first fixing member 50 is provided between the first shell 101 and the second shell, the first fixing member 50 as follows: Figure 3 and 4 As shown, the first shell 101 and the second shell together form an inlet 12, through which the suction head 20 is inserted into the shell 10.

[0051] The inlet 12 is provided with a first insertion part, and the first fixing part 50 includes a second insertion part. The second insertion part is inserted and connected to the first insertion part, thereby ensuring a stable and well-sealed connection between the suction head 20 and the housing 10, achieving simple and firm assembly.

[0052] like Figure 3 As shown, the second insertion part includes a first insertion slot 53 and a second insertion slot 54, which are arranged facing each other, as shown. Figure 6As shown, the first plug-in portion includes a first plug-in protrusion 13 and a second plug-in protrusion 14, which extend in opposite directions to engage with two plug-in slots on the second plug-in portion.

[0053] Figure 7 The assembled structure is shown. During assembly, the first insertion protrusion 13 is inserted into the first insertion slot 53 of the first shell 101 (or the second shell), and the second insertion protrusion 14 is inserted into the second insertion slot 54 of the first shell 101 (or the second shell). Then the second shell (or the first shell 101) is fastened together. The first fastener 50 and the shell 10 can be quickly and easily assembled and can remain firm and sealed during use, avoiding the problem of loosening or falling off between parts.

[0054] Furthermore, such as Figure 3 As shown, the first fixing member 50 has a plug-in interface 52, the interface direction of the plug-in interface 52 extends along the first direction L1, and the suction head 20 includes a plug-in nozzle 23, which is inserted into the plug-in interface 52 and fixedly connected to the plug-in interface 52.

[0055] The fit between the connector 23 and the connector 52 makes the connection between the suction head 20 and the housing 10 not only simple but also secure and durable. During the insertion process, to ensure a tight seal at the connection point, a first sealing ring is fitted onto the outside of the connector 23. When the connector 23 is inserted into the connector 52, the sealing ring and the connector 52 form a tight contact, effectively preventing liquid or gas leakage and ensuring good sealing performance of the equipment during operation.

[0056] In this embodiment, the connection between the suction head 20 and the first fixing member 50 adopts a lockable plug-in design. Specifically, as shown below... Figure 3 and 4 As shown, the plug-in interface 52 has a groove 521, and the suction head 20 has a protrusion that mates with the groove 521.

[0057] The protrusion is initially in an raised state. When the insertion nozzle 23 of the suction head 20 is inserted into the insertion interface 52 of the first fixing member 50, the protrusion will automatically snap into the groove 521, thereby achieving a locking connection between the suction head 20 and the first fixing member 50.

[0058] When it is necessary to disassemble the suction head 20, simply trigger the trigger on the suction head 20 to disengage the protrusion from the groove 521, thus releasing the suction head 20. The user can then easily remove the suction head 20 from the first fixing member 50. This ensures a stable connection between the suction head 20 and the first fixing member 50, while simplifying the disassembly process and improving the ease of use of the device.

[0059] Furthermore, such as Figure 1As shown, the first fixing member 50 is sleeved with a second sealing ring 412. The liquid storage tank 40 includes a liquid inlet pipe 41, and a liquid inlet channel 410 is provided inside the liquid inlet pipe 41. A liquid inlet 411 is provided on the side of the liquid inlet pipe 41 near the first fixing member 50. When the first fixing member 50 is inserted into the liquid inlet 411, the second sealing ring 412 abuts against the first fixing member 50 and the liquid inlet 411.

[0060] When the first fixing member 50 is inserted into the liquid inlet 411, the second sealing ring 412 is in close contact with the liquid inlet 411 of the liquid storage tank 40 and the first fixing member 50, ensuring that the surface cleaning equipment 100 will not have any liquid leakage problems during operation.

[0061] An annular groove is provided at the position where the first fixing member 50 is sleeved with the second sealing ring 412. The second sealing ring 412 is embedded in the annular groove. The cross-section of the liquid inlet 411 and the cross-section of the annular groove can both be set to be circular.

[0062] Continue as Figure 1 As shown, the cross-sectional dimensions of the inner flow channel 51 in this embodiment are the same as those of the liquid inlet flow channel 410. The inner flow channel 51 and the liquid inlet flow channel 410 are aligned. This design ensures a perfect connection between the inner flow channel 51 and the liquid inlet flow channel 410. There is no change in the diameter of the fluid at the connection point, which reduces the resistance or turbulence that may occur during the transition process. This ensures that the liquid can flow into the storage tank 40 stably and quickly, improving the overall cleaning effect and equipment performance.

[0063] Furthermore, the first direction L1 is set along the opening direction of the inlet 21, and the second direction L2 is set along the vertical direction of the housing 10.

[0064] The first direction L1 is aligned with the opening direction of the suction head 20 inlet 21, ensuring that the suction head 20 of the surface cleaning device 100 faces the surface to be cleaned (e.g., a window) during use. Figure 1 As shown, when the user holds the handle, the suction head 20 points to the upper left, allowing wastewater to be effectively drawn from the window surface into the device and into the suction head channel 22 through the inlet 21. The setting of the first direction L1 ensures the relative angle between the suction head 20 and the surface to be cleaned during operation, which helps to ensure smooth liquid intake and cleaning effect.

[0065] The second direction, L2, is set vertically along the housing 10, ensuring that the liquid flows smoothly downwards from the suction head 20 through the inner flow channel 41 into the storage tank 40. The liquid flow path is parallel to the vertical direction of the equipment, avoiding unnecessary bends and liquid stagnation, effectively reducing resistance and residence time during the flow process, thereby improving cleaning efficiency. Through the rational setting of these two directions, this embodiment optimizes the liquid flow path, ensuring high efficiency and stable fluid flow during cleaning operations.

[0066] Furthermore, such as Figure 1 As shown, the liquid storage tank 40 includes an air outlet pipe 42, and a first air outlet channel 421 is provided inside the air outlet pipe 42. The surface cleaning device 100 also includes an air outlet component 70 and an impeller 31 driven by a motor 30.

[0067] The air outlet pipe 42 is connected to the air outlet component 70. The air outlet component 70 forms a second air outlet channel 71. The second fixing component 60 and the air outlet component 70 together form an impeller cavity 63. The impeller 31 is housed in the impeller cavity 63. The second fixing component 60 forms a third air outlet channel 61. The first air outlet channel 421, the second air outlet channel 71, the impeller cavity 63, the third air outlet channel 61 and the air outlet 11 are connected in sequence.

[0068] After the air and liquid mixture flows into the storage tank 40, the gas and liquid separate. The impeller 31 rotates, driving the airflow. The gas passes through the first outlet air passage 421, the second outlet air passage 71, the impeller cavity 63, and the third outlet air passage 61 in sequence, and is finally discharged through the outlet 11.

[0069] The second fastener 60 includes a receiving groove 62, the receiving groove 62 as follows: Figure 8 and 9 As shown, the third air outlet duct 61 and the impeller cavity 63 are as follows Figure 9 As shown, the first fixing member 50 includes a limiting part 55, the limiting part 55 as follows: Figure 4 As shown, the motor 30 is placed in the receiving groove 62. The end of the motor 30 away from the impeller 31 is fixed in the limiting part 55. The first fixing part 50 and the second fixing part 60 together fix the motor 30, making the rotation of the impeller 31 more stable and efficient, and improving the overall working performance of the equipment.

[0070] In addition, both the first fixing component 50 and the second fixing component 60 are designed as one-piece molded parts, which enhances the integrity and durability of the equipment and ensures the long-term stable operation of the equipment.

[0071] Compared with the prior art, this embodiment has the following beneficial effects: The surface cleaning device 100 significantly improves liquid flow efficiency and enhances the cleaning performance of the device by optimizing the flow channel design. Specifically, the suction head flow channel 22 and the inner flow channel 51 adopt a straight extension and inclined connection method. These two flow channels themselves do not have complex curved structures; they are only spliced ​​at an inclined angle at the connection point. That is, except for the splicing position, the flow path of the fluid before entering the liquid storage tank 40 is straight, without any unnecessary bends or obstructions. The fluid can more smoothly enter the liquid storage tank 40 through the connecting channel, reducing flow time and avoiding the liquid retention problem in traditional structures. Significant improvements have been made in fluid flow speed and smoothness, thereby increasing the cleaning efficiency of the device.

[0072] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. 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.

[0073] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
