Detailed Implementation

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] Combination Figure 1 and Figure 2The power unit 100 according to an embodiment of the present invention can be used in cleaning equipment. The power unit 100 includes: a housing assembly 10, a suction motor 20, and a battery 30. The housing assembly 10 has a first receiving cavity 111 and a second receiving cavity 112, which are disposed within the housing assembly 10. The suction motor 20 is disposed in the first receiving cavity 111; the battery 30 is disposed in the second receiving cavity 112 and is electrically connected to the suction motor 20. Specifically, the battery 30 can be used to supply power to the suction motor 20. In addition, the battery 30 can also be used to supply power to the roller brush, control components, etc. of the cleaning equipment. By integrating the battery 30 and the suction motor 20 into the housing assembly 10, modular design of the cleaning equipment is facilitated, making the structure of the cleaning equipment more compact. For example, the cleaning equipment can be a vacuum cleaner, a floor scrubber, a mite remover, etc.

[0025] The housing assembly 10 also includes an air outlet 113 and an air outlet 114. The air outlet 114 is located on the outer side of the housing assembly 10. The air outlet 113 connects the first receiving cavity 111 and the air outlet 114. The first receiving cavity 111 and the air outlet 113 are separated from the second receiving cavity 112. Specifically, the airflow discharged by the suction motor 20 enters the air outlet 113 through the first receiving cavity 111 and is discharged to the outside of the cleaning equipment through the air outlet 114. The air outlet 114 is located on the outer side of the housing assembly 10. In other words, the power unit 100 has a side-discharge structure, and the airflow discharged by the suction motor 20 can be directly discharged to the outside of the cleaning equipment through the air outlet 114. It is not necessary to set an air outlet channel on the body of the cleaning equipment, which simplifies the structure of the cleaning equipment. In addition, the first receiving cavity 111 and the second receiving cavity 112 are separated, and the air outlet channel 113 is separated from the second receiving cavity 112, so as to prevent the airflow discharged by the suction motor 20 from containing moisture and affecting the battery 30, thereby maintaining a dry working environment in the second receiving cavity 112 and improving the service life of the battery 30.

[0026] Taking a floor scrubber as an example of cleaning equipment, when the floor scrubber is working, the clean water in the water tank is sprayed onto the ground, and then the ground is cleaned by a roller brush or mop. The suction motor 20 serves as a power source to suck the sewage and garbage on the ground into the sewage tank. The gas-liquid separation device in the sewage tank may not be able to completely separate the water vapor in the airflow, which may easily lead to the airflow sucked in by the suction motor 20 containing water vapor. By separating the second receiving chamber 112 from the first receiving chamber 111 and separating the second receiving chamber 112 from the air outlet duct 113, the airflow containing water vapor discharged by the suction motor 20 is prevented from entering the battery 30, thereby improving the service life of the battery 30.

[0027] According to the embodiment of the present invention, the power unit 100 of the cleaning equipment integrates the suction motor 20 and the battery 30 into the housing assembly 10, and the air outlet 114 of the power unit 100 is located on the outer side of the housing assembly 10, which facilitates the modular design of the cleaning equipment and eliminates the need to set an air outlet structure on the cleaning equipment. In addition, the first receiving cavity 111 and the air outlet channel 113 are separated from the second receiving cavity 112 to avoid the suction motor 20 from affecting the battery 30 during the exhaust process and to improve the service life of the battery 30.

[0028] The housing assembly 10 is provided with an air outlet 113 and an air outlet 114. For example, the housing assembly 10 may include an outer shell 12 and a first inner shell 13. The outer side of the outer shell 12 may be provided with a through hole. A part of the first inner shell 13 is disposed inside the outer shell 12 and defines the air outlet 113 and the air outlet 114. The air outlet 114 extends out of the through hole, so that the air outlet 113 is separated from the second receiving cavity 112. Alternatively, the housing assembly 10 may include an outer shell 12 and a first inner shell 13. The air outlet 114 is disposed on the side wall of the outer shell 12. The first inner shell 13 is disposed inside the outer shell 12 and defines the air outlet 113. The air outlet 113 is connected to the air outlet 114. A sealing structure is provided between the air outlet 113 and the air outlet 114 to separate the air outlet 113 from the second receiving cavity 112.

[0029] Furthermore, the first receiving cavity 111 and the second receiving cavity 112 are separated. Exemplarily, the first receiving cavity 111 and the second receiving cavity 112 may be composed of separately formed shell portions, or the shell assembly 10 may have a sealing structure that closes the gap between the first receiving cavity 111 and the second receiving cavity 112, to prevent airflow discharged from the suction motor 20 from entering the second receiving cavity 112 through the gap between the first receiving cavity 111 and the second receiving cavity 112, thus affecting the battery 30 and ensuring that the second receiving cavity 112 provides a dry working environment for the battery 30. The suction motor 20 is located in the first receiving cavity 111, and the battery 30 is located in the second receiving cavity 112. Exemplarily, the battery 30 may be surrounding the outside of the suction motor 20, or the battery 30 may be located above the suction motor 20.

[0030] Combination Figure 2 and Figure 3In some embodiments of this utility model, the housing assembly 10 includes an outer shell 12 and at least a portion of a first inner shell 13 disposed inside the outer shell 12. An air outlet 114 is disposed on the side wall of the outer shell 12, and an air outlet channel 113 is disposed in the first inner shell 13. A first sealing member 40 is provided between the periphery of the air outlet end 1131 of the air outlet channel 113 and the periphery of the air outlet 114. The first sealing member 40 is used to seal the gap between the periphery of the air outlet end 1131 of the air outlet channel 113 and the periphery of the air outlet 114. Specifically, the air outlet end 1131 of the air outlet channel 113 can be used to connect with the air outlet 114. The air outlet channel 113 serves as a guide, combined with... Figure 2 As shown, the arrows indicate the direction of airflow. The airflow discharged by the suction motor 20 is discharged to the outside of the cleaning equipment through the air outlet 114 via the air outlet 113. By setting the first sealing element 40, a moisture barrier layer can be formed to prevent moisture in the air outlet 113 from entering the battery 30 through the gap between the air outlet 114 and the air outlet 113, so that the second receiving cavity 112 maintains a dry working environment, thereby improving the service life of the battery 30.

[0031] Furthermore, by providing a first sealing element 40 around the periphery of the air outlet 1131 of the air outlet channel 113 and the periphery of the air outlet 114, the structure of the power unit 100 can be simplified. It eliminates the need for complex injection-molded waterproof channels within the power unit 100, facilitating its manufacturing process. It is understood that the battery 30 generates heat during charging and discharging; therefore, the second receiving cavity 112 can be designed as a non-enclosed structure to facilitate heat dissipation from the battery 30 and improve its lifespan. By sealing the gap between the air outlet channel 113 and the air outlet 114 with the first sealing element 40, it eliminates the need for complex waterproof channels inside the housing assembly 10, thereby simplifying the structure of the power unit.

[0032] Combination Figure 2 and Figure 3 Furthermore, the periphery of the air outlet 1131 of the air outlet duct 113 is opposite to the periphery of the air outlet 114 along the air outlet direction, and the air outlet direction is perpendicular to the axis of the suction motor 20. As shown in the attached figure, the air outlet direction is AA direction, and the axis of the suction motor 20 extends along BB direction. For example, when the cleaning equipment is in an upright state, the axis of the suction motor 20 extends in the vertical direction, and the air outlet direction can be left and right, so that the power unit 100 is constructed with a side air outlet structure. The airflow discharged by the suction motor 20 does not need to pass through the body of the cleaning equipment and is directly discharged from the power unit 100. That is to say, there is no need to set an air outlet channel on the body of the cleaning equipment, simplifying the structure of the cleaning equipment.

[0033] Combination Figure 3The first sealing element 40 includes a first sealing ring 41, at least a portion of which is disposed along the air outlet direction between the periphery of the air outlet end 1131 of the air outlet channel 113 and the periphery of the air outlet 114. For example, the suction motor 20 and the battery 30 can be located on the upper side of the first inner shell 13. The airflow discharged by the suction motor 20 is discharged through the air outlet channel 113 and from the air outlet 114. The first sealing ring 41 can seal the gap between the air outlet channel 113 and the air outlet 114 in the air outlet direction, preventing moisture-laden airflow from entering the second receiving cavity 112 upwards through the gap between the air outlet channel 113 and the air outlet 114, thus affecting the battery 30 and improving the service life of the battery 30.

[0034] The first sealing ring 41 can be configured as an annular sealing ring surrounding the air outlet 1131.

[0035] Combination Figure 4 In some embodiments of this utility model, the first inner shell 13 includes a first groove 131 located around the air outlet end 1131 of the air outlet channel 113, and the first sealing ring 41 includes a second groove 411. The edge of the first inner shell 13 is embedded in the second groove 411, and the edge of the first sealing ring 41 is embedded in the first groove 131. Specifically, the first groove 131 and the second groove 411 can be arranged along the air outlet direction to form a structure in which the first sealing ring 41 and the first inner shell 13 are nested together, thereby improving the stability of the fit between the first sealing ring 41 and the first inner shell 13, preventing the first sealing ring 41 from shifting after long-term use of the cleaning equipment and affecting the sealing performance, and thus improving the sealing effect on the second receiving cavity 112.

[0036] Combination Figure 3 In some embodiments of this utility model, the inner wall of the outer shell 12 has a first supporting rib 121, and the periphery of the first inner shell 13 is provided with a second supporting rib 132 extending out of the air outlet end 1131 of the air outlet channel 113. The first supporting rib 121 and the second supporting rib 132 are stacked along the axial direction (BB direction) of the suction motor 20, and the first sealing member 40 includes a second sealing ring 42, at least a portion of the second sealing ring 42 being disposed between the first supporting rib 121 and the second supporting rib 132 along the axial direction. For example, when the cleaning device is in an upright state, the axis of the suction motor 20 extends in the vertical direction. By providing a first support rib 121 on the inner wall of the outer shell 12, the first inner shell 13 can be supported and positioned, thereby improving the stability of the first inner shell 13. The second sealing ring 42 is provided between the first support rib 121 and the second support rib 132 along the axial direction, which can seal the gap between the first inner shell 13 and the outer shell 12 in the axial direction, preventing airflow containing moisture from entering the second receiving cavity 112 through the gap between the outer shell 12 and the first inner shell 13, thus affecting the battery 30.

[0037] In some embodiments of this utility model, the periphery of the air outlet end 1131 of the air outlet channel 113 is opposite to the periphery of the air outlet 114 along the air outlet direction, and the air outlet direction is perpendicular to the axis of the suction motor 20. The inner wall of the outer shell 12 has a first support rib 121, and the periphery of the first inner shell 13 is provided with a second support rib 132 extending out of the air outlet end 1131 of the air outlet channel 113. The first support rib 121 and the second support rib 132 are stacked along the axial direction of the suction motor 20. The first sealing member 40 includes a first sealing ring 41 and a second sealing ring 42. At least a portion of the first sealing ring 41 is disposed along the air outlet direction between the periphery of the air outlet end 1131 of the air outlet channel 113 and the periphery of the air outlet 114. At least a portion of the second sealing ring 42 is disposed along the axial direction between the first support rib 121 and the second support rib 132. Specifically, the first sealing ring 41 can seal the gap between the air outlet channel 113 and the air outlet 114 in the air outlet direction, preventing water vapor-containing airflow from entering the second receiving cavity 112 upwards through the gap between the air outlet channel 113 and the air outlet 114, thus preventing it from affecting the battery 30. The first sealing ring 41 forms a first water vapor barrier layer, preventing water vapor from entering the battery 30 upwards through the gap between the air outlet channel 113 and the air outlet 114. The second sealing ring 42 forms a second water vapor barrier layer, used to seal the small amount of water vapor that may overflow from the first sealing ring 41. By setting the first sealing ring 41 and the second sealing ring 42 in cooperation, two sealing structures are formed between the first inner shell 13 and the outer shell 12, effectively preventing water vapor from entering the second receiving cavity 112, providing a dry working environment for the battery 30, and improving the service life of the battery 30.

[0038] Combination Figure 5 In some embodiments of this utility model, the housing assembly 10 includes an outer shell 12, a first inner shell 13, and a second inner shell 14. At least a portion of the second inner shell 14 is disposed inside the outer shell 12. A first receiving cavity 111 is disposed inside the second inner shell 14, and a second receiving cavity 112 is disposed between the second inner shell 14 and the outer shell 12. Specifically, the battery 30 can be arranged around the outside of the suction motor 20, making the structure of the power device 100 compact. The inner side of the second inner shell 14 defines the first receiving cavity 111 for accommodating the suction motor 20, and the second receiving cavity 112 for accommodating the battery 30 is defined between the second inner shell 14 and the outer shell 12. This makes the structure of the suction motor 20 more compact and facilitates heat dissipation of the battery 30 during charging and discharging, avoiding excessive heat concentration in the battery 30 and thus improving the service life of the battery 30.

[0039] Furthermore, at least a portion of the first inner shell 13 is located inside the outer shell 12, the air outlet 114 is located on the side wall of the outer shell 12, the air outlet channel 113 is located in the first inner shell 13, and a second sealing member 50 is provided between the first inner shell 13 and the second inner shell 14 to seal the fitting gap between the second inner shell 14 and the first inner shell 13. Specifically, the airflow discharged by the suction motor 20 enters the air outlet channel 113 from the first receiving cavity 111 and is discharged to the outside of the cleaning equipment through the air outlet 114. The second sealing member 50 can seal the gap between the second inner shell 14 and the first inner shell 13, preventing moisture from entering the second receiving cavity 112 from the first receiving cavity 111, thus maintaining a dry working environment in the second receiving cavity 112 and improving the service life of the battery 30.

[0040] The second inner shell 14 can be supported above the first inner shell 13, making the structure of the power unit 100 more compact. Optionally, the battery 30 is arranged around the outside of the suction motor 20 and above the air outlet duct 113, so that the suction motor 20 can carry away the heat of the battery 30 during the exhaust process, avoiding excessive heat of the battery 30 during the operation of the power unit 100, thereby improving the service life of the battery 30.

[0041] Combination Figure 2 and Figure 5 In some embodiments of this utility model, the first inner shell 13 further defines an air inlet channel 133, which connects to the suction motor 20, and an air outlet channel 113 surrounds the outside of the air inlet channel 133. For example, the cleaning equipment can be a floor scrubber, which may include a wastewater tank. During the cleaning process, the suction motor 20 operates to generate negative pressure at the suction inlet, and the airflow sequentially enters the floor brush, wastewater tank, air inlet channel 133, suction motor 20, and air outlet channel 113 through the suction port on the floor brush, and finally exits through the air outlet 114 to the outside of the cleaning equipment. The first inner shell 13 serves to support and position the suction motor 20. By integrating the air inlet channel 133 into the first inner shell 13 and surrounding the air outlet channel 113 with the outside of the air inlet channel 133, the air duct layout of the power unit 100 is optimized, the structure of the power unit 100 is simplified, and the air outlet resistance of the power unit 100 is reduced, making the air outlet of the power unit 100 smoother and thus improving the working efficiency of the suction motor 20. The air outlet channel 113 can be constructed as an annular channel surrounding the air inlet channel 133.

[0042] Combination Figure 5Furthermore, the air outlet 114 includes a first outlet 1141 located on the left side wall of the outer casing 12 and a second outlet 1142 located on the right side wall of the outer casing 12. The first inner casing 13 includes a first interface 134 and a second interface 135 located inside the outer casing 12. The first interface 134 is connected to the first outlet 1141, and the second interface 135 is connected to the second outlet 1142. By providing air outlets 114 on both the left and right sides of the outer casing 12, the air outlet efficiency of the power unit 100 is improved, thereby improving the working efficiency of the suction motor 20.

[0043] In conjunction with the foregoing, a first sealing ring 41 may be provided between the periphery of the first interface 134 and the first outlet 1141, and a first sealing ring 41 may be provided between the periphery of the second interface 135 and the second outlet 1142. This can seal the gap between the first interface 134 and the first outlet 1141, as well as the gap between the second interface 135 and the second outlet 1142, in the air outlet direction, preventing airflow containing moisture from entering the second receiving cavity 112 and affecting the battery 30. In addition, the first interface 134 and the second interface 135 are located inside the outer casing 12, so that the docking structure of the air outlet channel 113 and the air outlet 114 is hidden inside the outer casing 12.

[0044] This utility model also proposes a cleaning device, including: a body and the aforementioned power unit 100. The power unit 100 is located in the body. By integrating the suction motor 20 and the battery 30 together, the modular design of the cleaning device is facilitated, making the structure of the cleaning device more compact. Furthermore, the air outlet 114 is located on the outer side of the housing assembly 10 of the power unit 100, enabling the power unit 100 to have a side-exhaust structure. This eliminates the need for an air outlet channel on the body, further simplifying the structure of the cleaning device and facilitating its manufacturing. The second receiving cavity 112, which houses the battery 30, is separated from the first receiving cavity 111 and is also separated from the air outlet channel 113, reducing the impact of the suction motor 20 on the battery 30 during exhaust and extending the battery 30's lifespan.
