Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0057] The control unit 100 of the cleaning equipment according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0058] like Figures 1 to 4 As shown, the control unit 100 of the cleaning equipment according to an embodiment of the present invention includes: a housing assembly 10, a fan assembly 20, and a separator 30.
[0059] The housing assembly 10 has a heat dissipation space 11 and a placement cavity 12. The placement cavity 12 is arranged around the heat dissipation space 11 and is used to place the power supply component 121.
[0060] The power supply unit 121 is used to supply electrical energy for the operation of the cleaning equipment. It can be understood that the power supply unit 121 supplies electrical energy to the cleaning equipment, enabling the cleaning equipment to clean the area to be cleaned while moving. Of course, it is understood that the cleaning equipment moving while cleaning the area to be cleaned does not represent a limitation of this application; the cleaning equipment can also be in other operating states.
[0061] The fan assembly 20 is located within the heat dissipation space 11. The partition 30 is located between the outer wall of the fan assembly 20 and the inner wall of the heat dissipation space 11 to define the air inlet channel 111 and the air outlet channel 112. The air inlet channel 111 is provided with an air inlet 1111, and the air outlet channel 112 is provided with an air outlet 1121. One end of the air inlet channel 111 away from the air inlet 1111 is connected to one end of the air outlet channel 112 away from the air outlet 1121. The fan outlet 221 of the fan assembly 20 is connected to the air inlet 1111.
[0062] The fan outlet 221 of the fan assembly 20 is connected to the air inlet 1111. It can be understood that when the fan assembly 20 is working, it supplies air to the air inlet 1111 to form an airflow. The end of the air inlet channel 111 away from the air inlet 1111 is connected to the end of the air outlet channel 112 away from the air outlet 1121. The airflow flows in the air inlet channel 111 and the air outlet channel 112. It can be understood that the separator 30 is provided between the outer wall of the fan assembly 20 and the inner wall of the heat dissipation space 11 to limit the air inlet channel 111 and the air outlet channel 112. The airflow flowing in the air inlet channel 111 and the air outlet channel 112 can carry away the heat generated by the power supply component 121 when it is working, thereby achieving the effect of heat dissipation of the housing assembly 10 and the power supply component 121 by the fan assembly 20 itself.
[0063] In related technologies, the airflow generated by the fan is directly blown into the larger slot in the middle of the battery module. The airflow in the slot is relatively turbulent, resulting in poor heat dissipation.
[0064] This application separates the air intake channel 111 and the air outlet channel 112 by setting a separator 30, so that the airflow flows in an orderly manner, avoids airflow turbulence, and improves the heat dissipation effect. Among them, the end of the air intake channel 111 opposite to the air inlet 1111 is connected to the end of the air outlet channel 112 opposite to the air outlet 1121, so the airflow flows in one direction, and the airflow flows more orderly, further improving the heat dissipation effect.
[0065] The air intake channel 111 can be one or more. By setting multiple air intake channels 111, the airflow can be made to flow in an orderly manner, which further improves the heat dissipation effect.
[0066] The air outlet channel 112 can be one or more. By setting multiple air outlet channels 112, the airflow can be made to flow in an orderly manner, which further improves the heat dissipation effect.
[0067] Meanwhile, the placement cavity 12 is arranged around the heat dissipation space 11, and the power supply component 121 is placed inside the placement cavity 12 to improve the heat dissipation effect.
[0068] According to the control unit 100 of the cleaning equipment of the present invention, an air inlet channel 111 and an air outlet channel 112 are separated by a separator 30. Compared with the related art where the airflow generated by the fan is directly blown into the larger slot in the middle of the battery assembly, this application makes the airflow flow in an orderly manner, avoids airflow turbulence, and improves the heat dissipation effect. At the same time, the placement cavity 12 is arranged around the heat dissipation space 11, and the power supply component 121 is placed in the placement cavity 12 to improve the heat dissipation effect.
[0069] In some embodiments, the air outlet 1121 is used to connect to the main exhaust outlet of the cleaning equipment for unified discharge.
[0070] Specifically, the cleaning equipment is also equipped with a dust collection bag to collect dust or particles mixed in with the airflow discharged from the air outlet 1121.
[0071] In some embodiments, the blower assembly 20 has a blower suction port 223, which is adapted to connect to the sewage tank 200 for pumping out the negative pressure of the sewage tank 200.
[0072] In some embodiments, the fan assembly 20 has a fan intake 223, which is suitable for cleaning the area to be cleaned. For example, the fan intake 223 generates suction to remove sewage, dust, or particles from the area to be cleaned. This application makes full use of its own fan assembly 20 to dissipate heat from its own power supply component 121, thereby improving utilization.
[0073] like Figures 1 to 6 As shown, in some embodiments, the fan assembly 20 includes a fan shroud 21 and a fan 22. The fan shroud 21 is disposed within the heat dissipation space 11. The separator 30 cooperates with the fan shroud 21 and the housing assembly 10 respectively. The air inlet 1111 is located on one side of the fan shroud 21. At least a portion of the fan 22 is disposed within the fan shroud 21. By disposing at least a portion of the fan 22 within the fan shroud 21, and by disposing the fan shroud 21 within the heat dissipation space 11, the fan shroud 21 provides a certain degree of protection, preventing the fan 22 from short-circuiting or becoming contaminated.
[0074] The air inlet 1111 is located on one side of the fan cover 21, which makes the airflow path clearer, further avoids turbulence, and improves the heat dissipation effect.
[0075] like Figure 1 , Figure 2 and Figure 10As shown, in some specific implementations, the separator 30 cooperates with the fan cover 21 and the housing assembly 10 respectively to define the air inlet channel 111 and the air outlet channel 112. The airflow flows in the air inlet channel 111 and the air outlet channel 112 and at the same time plays a role in heat dissipation of the fan 22.
[0076] like Figure 6 As shown, in some embodiments, one of the separator 30 and the fan cover 21 is provided with a positioning protrusion 214, and the other is provided with a positioning groove 321. The positioning protrusion 214 and the positioning groove 321 cooperate to position the separator 30.
[0077] For example, the fan cover 21 is provided with a positioning protrusion 214, and the partition 30 is provided with a positioning groove 321. The positioning protrusion 214 and the positioning groove 321 cooperate to position the partition 30; or, the partition 30 is provided with a positioning protrusion 214, and the fan cover 21 is provided with a positioning groove 321. The positioning protrusion 214 and the positioning groove 321 cooperate to position the partition 30.
[0078] More specifically, there are multiple positioning protrusions 214 and multiple positioning grooves 321. The multiple positioning grooves 321 cooperate with the multiple positioning protrusions 214 to make the separator 30 as a whole stable.
[0079] like Figure 3 As shown, in some embodiments, the fan 22 is provided with multiple fan outlets 221, which are spaced apart circumferentially. By providing multiple fan outlets 221 arranged circumferentially, airflow is discharged from the fan outlets 221 to all directions, increasing the flow rate.
[0080] In some specific implementations, multiple fan outlets 221 are oriented clockwise or counterclockwise towards the fan 22. By setting multiple fan outlets 221 to face the fan 22 clockwise or counterclockwise, the airflow discharged from the fan outlets 221 flows spirally around the fan 22, improving the heat dissipation effect.
[0081] For example, multiple fan outlets 221 face clockwise from the fan 22; or multiple fan outlets 221 face counterclockwise from the fan 22.
[0082] like Figures 1 to 6 As shown, in some embodiments, the separator 30 includes a mounting portion 31 and a plurality of separator portions 32.
[0083] The first ends of multiple partitions 32 are respectively connected to the mounting part 31, which is located on the fan cover 21. The multiple partitions 32 cooperate with the housing assembly 10 to separate the air intake channel 111 and the air outlet channel 112. By setting multiple partitions 32 to cooperate with the housing assembly 10 to separate the air intake channel 111 and the air outlet channel 112, the structures of the air intake channel 111 and the air outlet channel 112 are clear, the airflow path is clear, and the heat dissipation effect is improved.
[0084] The mounting part 31 is located on the fan cover 21, and the first ends of the multiple partitions 32 are respectively connected to the mounting part 31, so that the partition 30 is more stably positioned on the fan cover 21.
[0085] In some embodiments, the mounting portion 31 is fitted over a portion of the outer side of the fan housing 21. By fitting the mounting portion 31 over a portion of the outer side of the fan housing 21, the mounting portion 31 is stabilized on the fan housing 21, thereby improving stability.
[0086] In some embodiments, the air intake channel 111 and the air outlet channel 112 are spaced apart along the circumferential direction of the housing assembly 10 to improve heat dissipation.
[0087] In some embodiments, there are multiple air intake channels 111, which are spaced apart along the circumferential direction of the housing assembly 10 to avoid turbulence and improve heat dissipation.
[0088] In some embodiments, there are multiple air outlet channels 112, which are spaced apart along the circumferential direction of the housing assembly 10 to avoid turbulence and improve heat dissipation.
[0089] In some embodiments, the air intake channel 111 and the air outlet channel 112 are densely distributed in the circumferential direction of the housing assembly 10 to increase the contact area and improve the heat dissipation effect.
[0090] In some specific embodiments, there are multiple partitions 32, which are distributed at intervals along the circumferential direction of the fan cover 21 to separate the air intake channel 111 and the air outlet channel 112, thereby improving the heat dissipation effect.
[0091] For example, there may be two partitions 32, which separate an air intake passage 111 and an air outlet passage 112; or, there may be three partitions 32, which separate an air intake passage 111 and two air outlet passages 112; or, there may be three partitions 32, which separate two air intake passages 111 and one air outlet passage 112; of course, there may be more partitions 32, which will not be elaborated here.
[0092] like Figure 2As shown, in some embodiments, a connecting channel 113 is provided between the air intake channel 111 and the air outlet channel 112. One end of the connecting channel 113 is connected to the end of the air intake channel 111 opposite to the air inlet 1111, and the other end is connected to the end of the air outlet channel 112 opposite to the air outlet 1121. By setting the connecting channel 113, the airflow path is made clearer, and the heat dissipation effect is improved.
[0093] In some specific embodiments, the mounting part 31, the partition part 32 and the inner wall of the heat dissipation space 11 together define a communication channel 113 to improve the heat dissipation effect.
[0094] like Figure 2 , Figure 10 As shown, in some embodiments, the inner wall of the housing assembly 10 is provided with an insertion groove 13, and a portion of the partition 32 is located in the insertion groove 13. By providing the insertion groove 13 to accommodate the partition 32, it can be understood that the cooperation between the insertion groove 13 and the partition 32 prevents the partition 32 from deforming, and the insertion groove 13 plays a positioning role, so that the partition 32 is stable within the predetermined space.
[0095] More specifically, the insertion groove 13 is interference-fitted with the partition 32, which improves the sealing performance, prevents the channels on both sides of the partition 32 from connecting, and avoids airflow turbulence. For example, both sides of the partition 32 are air inlet channels 111, or both sides of the partition 32 are air outlet channels 112; or, one side of the partition 32 is an air inlet channel 111 and the other side is an air outlet channel 112.
[0096] In some specific embodiments, the inner wall of the housing assembly 10 is provided with a protrusion that restricts the extension groove 13.
[0097] In some other embodiments, an extension groove 13 is provided in the inner wall of the housing assembly 10.
[0098] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the separator 30 further includes a connector 33, the second ends of the plurality of separators 32 are connected to the connector 33, and the connector 33 cooperates with the fan cover 21. By providing the connector 33 to connect the second ends of the plurality of separators 32, the separator 30 is made more stable.
[0099] In some embodiments, the connector 33 abuts against the second housing 17, and the second housing 17, connector 33, partition 32 and fan cover 21 together define the air outlet passage 112, thereby improving the sealing performance.
[0100] In some embodiments, the separator 30 is constructed as a soft rubber component, which improves the sealing performance by utilizing the elastic deformation properties of the soft rubber component.
[0101] Specifically, the soft rubber component contacts or abuts against the inner wall of the fan cover 21 and the heat dissipation space 11, further improving the sealing performance. For example, the soft rubber component contacts the inner wall of the fan cover 21 and the heat dissipation space 11; or, the soft rubber component abuts against the inner wall of the fan cover 21 and the heat dissipation space 11.
[0102] In some embodiments, the soft rubber part is integrally molded into the fan cover 21, which facilitates positioning and reduces assembly difficulty.
[0103] For example, the fan cover 21 is constructed of rigid plastic, and the rigid and flexible plastic parts are integrally molded using a two-color injection molding process. Specifically, two-color injection molding refers to the process of injecting two different materials into the same mold to create a product formed from two materials.
[0104] In other embodiments, the soft rubber component is attached to the fan cover 21 by adhesive.
[0105] As shown in the figure Figure 2 As shown, in some embodiments, the fan 22 includes an annular support portion 222, a fan shroud 21 supported on the support portion 222, the electrical control portion of the fan 22 located inside the fan shroud 21, and the outlet of the fan 22 located on the side of the support portion 222 opposite to the fan shroud 21. By placing the electrical control portion of the fan 22 inside the fan shroud 21, with the fan outlet 221 located on the side of the support portion 222 opposite to the fan shroud 21, and the fan shroud 21 supported on the support portion 222, the electrical control portion of the fan 22 is enclosed within it, isolating the electrical control portion of the fan 22 from the external space and preventing sewage, dust, etc., from interfering with the electrical control portion.
[0106] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, an annular first seal 211 is provided between the support portion 222 and the fan cover 21. By providing the first seal 211 between the support portion 222 and the fan cover 21, the sealing performance between the support portion 222 and the fan cover 21 is improved, further reducing the probability of sewage, dust, etc., interfering with the electrical control components.
[0107] In some specific embodiments, the fan cover 21 is provided with a first sealing groove for positioning the first sealing member 211. The first sealing groove is sleeved on the support part 222, which improves the sealing performance.
[0108] like Figure 1 , Figure 2 As shown, in some embodiments, the fan cover 21 is provided with a wiring space 212, and the housing assembly 10 is provided with a wire passage hole 14 communicating with the wiring space 212.
[0109] Specifically, the control line of the fan 22 is run through the wiring space 212 and the wire hole 14 to facilitate the control of the fan 22.
[0110] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the housing assembly 10 includes an end cap 16, which has an end cap hole 165 connected to a wiring hole 14 for easy wiring.
[0111] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, a fourth sealing element 161 is provided between the end cap 16 and the first housing 15. The fourth sealing element 161 is arranged around the end cap hole 165 to improve the sealing performance.
[0112] like Figure 1 , Figure 2 and Figure 4 As shown, the end cap 16 is further provided with a fourth sealing groove 162 for positioning the fourth sealing element 161. The fourth sealing groove 162 is fitted onto the first housing 15, which improves the sealing performance.
[0113] In some embodiments, a portion of the fan cover 21 extends into the cable passage hole 14. By setting a portion of the fan cover 21 to extend into the cable passage hole 14, sewage, dust, and other contaminants are prevented from entering the cable passage hole 14.
[0114] like Figure 1 , Figure 2 As shown, in some embodiments, the separator 30 further includes a sealing part 34, which seals the gap between the fan cover 21 and the wire hole 14, thereby isolating the heat dissipation space 11 from the space outside the heat dissipation space 11, avoiding turbulence and improving the heat dissipation effect.
[0115] In some specific embodiments, the wire hole 14 is provided on the wall of the heat dissipation space 11, and the sealing part 34 is provided between the wall of the heat dissipation space 11 and the fan cover 21 to improve the sealing performance.
[0116] like Figure 1 , Figure 2 As shown, the separator 30 further includes the aforementioned mounting portion 31, and a sealing portion 34 is provided at the end of the mounting portion 31 facing the wire hole 14, with a set angle between the sealing portion 34 and the mounting portion 31. By setting a set angle between the sealing portion 34 and the mounting portion 31, the sealing performance is further improved.
[0117] For example, the sealing part 34 is vertically mounted on the part 31, and the sealing part 34 is located between the wall of the heat dissipation space 11 and the fan cover 21, which improves the sealing performance.
[0118] Furthermore, the fan cover 21 includes a stepped cover extension 213, a sealing part 34 located between one stepped surface of the cover extension 213 and the wall of the heat dissipation space 11, and a mounting part 31 fitted onto the other stepped surface of the cover extension 213, thereby improving the sealing performance.
[0119] like Figure 1 , Figure 2 As shown, the inner wall of the housing assembly 10 is provided with a housing protrusion 18 that protrudes in the direction away from the wire hole 14. The housing protrusion 18 abuts against the mounting part 31 to form a tortuous gap space, which further improves the sealing performance.
[0120] Furthermore, the shell protrusion 18 is constructed in a ring shape, and the mounting part 31 is fitted inside the ring-shaped shell protrusion 18, which further improves the sealing performance.
[0121] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, in some embodiments, the control unit 100 further includes a noise reduction component 40 for reducing noise, which is disposed within the heat dissipation space 11. By providing the noise reduction component 40 in the heat dissipation space 11, the noise of the airflow generated when the fan assembly 20 is operating is reduced, thereby reducing the noise generated by the cleaning equipment.
[0122] It is understandable that cleaning equipment can be used in places such as offices and bedrooms. This application reduces noise by setting noise reduction components 40, thereby improving the user experience.
[0123] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the housing assembly 10 includes a first housing 15, an end cap 16, and a second seal 164.
[0124] The first housing 15 is provided with a placement cavity 12, and the placement cavity 12 is provided with a placement opening 122.
[0125] End cap 16 is provided on the first housing 15 to seal the placement opening 122.
[0126] The second seal 164 is disposed between the first housing 15 and the end cap 16 and surrounds the placement opening 122.
[0127] The placement cavity 12 is used to place the power supply component 121. The placement opening 122 of the placement cavity 12 is suitable for placing the power supply component 121. The power supply component 121 can be placed into the placement cavity 12 through the placement opening 122. The end cover 16 seals the placement opening 122, and the end cover 16 isolates the power supply component 121 from the external space to prevent the power supply component 121 from being interfered with or contaminated by the external space. At the same time, a second sealing element 164 is provided between the first housing 15 and the end cover 16, which surrounds the placement opening 122, improves the sealing between the first housing 15 and the end cover 16, and further reduces the probability of the power supply component 121 being interfered with or contaminated.
[0128] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the end cap 16 is provided with a second sealing groove 163 for positioning the second seal 164. The second sealing groove 163 is fitted onto the first housing 15, thereby improving the sealing performance.
[0129] In some embodiments, the projection of the heat dissipation space 11 in the axial direction of the housing assembly 10 at least partially coincides with the projection of the placement cavity 12 in the axial direction of the housing assembly 10, thereby sufficiently dissipating heat from the power supply component 121 within the placement cavity 12.
[0130] In some specific embodiments, the projection of the placement cavity 12 onto the axial direction of the housing assembly 10 is completely within the projection of the heat dissipation space 11 onto the axial direction of the housing assembly 10, further improving the heat dissipation effect on the power supply component 121.
[0131] In some embodiments, the first housing 15 includes an inner housing and an outer housing.
[0132] The heat dissipation space 11 is located inside the inner shell. The outer shell is fitted onto the inner shell and together with the inner shell defines the placement cavity 12.
[0133] There are multiple power supply components 121, which are distributed at intervals along the circumferential direction of the first housing 15.
[0134] like Figure 4 As shown, in some embodiments, the power supply unit 121 is provided with a battery motherboard 1211.
[0135] like Figure 1 , Figure 2 , Figure 4 , Figures 7 to 11As shown, in some embodiments, the housing assembly 10 further includes a second housing 17, which is located on the side of the first housing 15 opposite to the placement opening 122. The second housing 17 is used to support the fan assembly 20 and has an air outlet 1121 and an air inlet 1111. By uniformly arranging the air inlet 1111 and the air outlet 1121 on the second housing 17, the airflow path of the entire structure is clearer, facilitating cooperation with other components on the cleaning equipment other than the control unit 100.
[0136] Specifically, the fan outlet 221 is located inside the second housing 17, and the space between the fan outlet 221 and the inner wall of the second housing 17 is structured as an air inlet 1111 to facilitate exhaust.
[0137] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, an annular third seal 171 is provided between the first housing 15 and the second housing 17. By providing an annular third seal 171 between the first housing 15 and the second housing 17, the sealing performance between the first housing 15 and the second housing 17 is improved, the probability of communication between the heat dissipation space 11 and the space outside the heat dissipation space 11 is reduced, and turbulence is avoided.
[0138] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, there are multiple third seals 171, which are arranged in the inward and outward directions. By providing multiple third seals 171 in the inward and outward directions, the sealing performance is further improved.
[0139] like Figure 1 , Figure 2 and Figure 4 As shown, in some specific embodiments, the first housing 15 and / or the second housing 17 are provided with a third sealing groove. The third sealing groove is used to position the third sealing element 171. The third sealing groove is sleeved on the first housing 15 and / or the second housing 17, which further improves the sealing performance.
[0140] For example, the first housing 15 is provided with a third sealing groove, which is used to position the third sealing element 171. The third sealing groove is sleeved on the second housing 17, which further improves the sealing performance.
[0141] Alternatively, the second housing 17 is provided with a third sealing groove, which is used to position the third sealing element 171. The third sealing groove is fitted onto the first housing 15, further improving the sealing performance.
[0142] Alternatively, the third sealing groove includes two third sealing sub-grooves 173, one of which is located in the first housing 15 and fitted onto the second housing 17, and the other is located in the second housing 17 and fitted onto the first housing 15, further improving the sealing performance.
[0143] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, a noise reduction component 40 is provided within the second housing 17 and located within the heat dissipation space 11. By providing the noise reduction component 40 in the heat dissipation space 11, the noise of the airflow generated when the fan assembly 20 is operating is reduced, thereby reducing the noise generated by the cleaning equipment.
[0144] It is understandable that cleaning equipment can be used in places such as offices and bedrooms. This application reduces noise by setting noise reduction components 40, thereby improving the user experience.
[0145] Part of the heat dissipation space 11 is located inside the second housing 17, and the other part of the heat dissipation space 11 is located inside the first housing 15. The heat dissipation space 11 passes through the first housing 15 and the second housing 17, and airflow flows in the heat dissipation space 11 to achieve the heat dissipation effect.
[0146] like Figure 7 As shown, in some embodiments, the second housing 17 is provided with an insertion slot 172, and the noise reduction component 40 is located in the insertion slot 172. By providing the insertion slot 172 for positioning the noise reduction component 40, assembly is facilitated.
[0147] More specifically, the noise reduction component 40 is constructed as a noise reduction plate with densely packed noise reduction holes. When the airflow passes through the noise reduction holes, it generates turbulence, which absorbs some of the sound wave energy, thereby reducing noise.
[0148] In some specific embodiments, the noise reduction component 40 is detachably disposed in the insertion slot 172, thereby allowing the noise reduction component 40 to be reused and facilitating cleaning and replacement of the noise reduction component 40.
[0149] When the cleaning equipment cleans the area to be cleaned, the suction generated by the fan assembly 20 will suck up sewage, dust or other substances. Sewage or dust may accumulate after passing through the noise reduction component 40, thereby affecting the effectiveness of the noise reduction component 40 and also affecting the performance of the cleaning equipment. This application provides an insertion slot 172 to make the noise reduction component 40 detachable, thereby facilitating the cleaning and replacement of the noise reduction component 40 and improving the user experience.
[0150] In some embodiments, there are multiple noise reduction components 40, which are sequentially arranged within the heat dissipation space 11 to reduce noise multiple times and improve the noise reduction effect. For example, there are two noise reduction components 40, which are arranged vertically to improve the noise reduction effect. Alternatively, there may be more than one noise reduction component 40, which will not be elaborated here.
[0151] like Figure 7 As shown, in some embodiments, the second housing 17 is provided with a mounting port 174, which is connected to the heat dissipation space 11. The mounting port 174 is provided with a detachable mounting cover plate 1741. By providing the mounting port 174 and the mounting cover plate 1741, it is convenient to remove and install the noise reduction sheet.
[0152] like Figure 1 , Figure 2 As shown, in some embodiments, the second housing 17 is provided with a cleaning air intake 175, which is adapted to connect to the sewage tank 200 and is used to remove the negative pressure of the sewage tank 200.
[0153] like Figure 1 , Figure 2 As shown, in some embodiments, the second housing 17 is provided with a cleaning air intake 175, which is connected to a ventilation fan intake 223. The cleaning air intake 175 is suitable for cleaning the area to be cleaned. For example, the cleaning air intake 175 generates suction to draw in sewage, dust, or particles from the area to be cleaned.
[0154] like Figure 1 , Figure 2 and Figure 4 As shown, in some specific embodiments, a fifth seal 177 is provided between the second housing 17 and the fan 22. The fifth seal 177 surrounds the cleaning air intake 175, thereby improving the sealing performance.
[0155] like Figure 1 , Figure 2 and Figure 4 As shown, more specifically, the second housing 17 is provided with a fifth sealing groove 176 for positioning the fifth seal 177. The fifth sealing groove 176 is fitted over the fifth seal 177, which improves reliability.
[0156] In some embodiments, in a cross-section parallel to the rotation axis of the fan assembly 20, the air inlet 1111 and the air outlet 1121 are located on opposite sides of the fan assembly 20 in the circumferential direction. By arranging the air inlet 1111 and the air outlet 1121 on opposite sides of the fan assembly 20 in the circumferential direction, airflow can flow around the fan assembly 20, increasing the airflow path, increasing the heat dissipation area, and improving the heat dissipation effect.
[0157] The fan assembly 20 has a circumferential range of 360°. The air inlet 1111 and the air outlet 1121 can be within a range of 180° on the left and 180° on the right, respectively, or they can be smaller ranges. For example, the air inlet 1111 and the air outlet 1121 together only occupy a range of 180°.
[0158] For example, such as Figure 1 As shown, Figure 1 The diagram shows a cross-section of the rotation axis of the parallel fan assembly 20 of the control unit 100. The air inlet 1111 is located on the right side of the fan assembly 20, and the air outlet 1121 is located on the left side of the fan assembly 20. This allows the airflow to flow around the fan assembly 20. The airflow flows through the right inner wall and then the left inner wall of the heat dissipation space 11. The airflow makes full contact with the inner wall of the heat dissipation space 11, which increases the flow path of the airflow, increases the heat dissipation area, and improves the heat dissipation effect.
[0159] like Figure 12 As shown, the cleaning device 1000 according to an embodiment of the present invention includes the control unit 100 described above.
[0160] According to the cleaning device 1000 of the present invention, an air inlet channel 111 and an air outlet channel 112 are separated by a separator 30. Compared with the related art where the airflow generated by the fan is directly blown into the larger slot in the middle of the battery pack, this application makes the airflow flow in an orderly manner, avoids airflow turbulence, and improves the heat dissipation effect. At the same time, the placement cavity 12 is arranged around the heat dissipation space 11, and the power supply component 121 is placed in the placement cavity 12, which improves the heat dissipation effect. The cleaning device does not trigger the charging over-temperature protection and shortens the charging time.
[0161] In some embodiments, the cleaning equipment 1000 is configured as any one of a floor scrubber, a sweeper, or a mop.
[0162] Other configurations and operations of the control unit 100 of the cleaning equipment according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
[0163] In the description of this specification, references to terms such as "embodiment," "example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0164] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
