In particular, referring to "the" object or "one" object is also intended to represent one of the possible multiple such objects.

[0053] Unless otherwise specified or explained, the terms "connection", "fixing", and the like should be broadly understood, for example, "connection" can be fixed connection, or detachable connection, or integrally connected, or electrically connected, or signal connected; "connection" can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0054] The example embodiments of the present disclosure first provide a dust collector, such as Figure 1 and Figure 2 As shown, the dust collector includes a main body assembly 10, a handle assembly 20, and a power assembly 30, the handle assembly 20 and the main body assembly 10 are connected, the handle assembly 20 includes a grip portion 21; the power assembly 30 is arranged on the upper side of the handle assembly 20, the power assembly 30 includes a front portion 31 and a rear portion 32, the volume of the rear portion 32 is greater than the volume of the front portion 31, the front portion 31 is the part of the power assembly 30 located on the side of the grip portion 21 close to the main body assembly 10 along a first direction, and the rear portion 32 is the part of the power assembly 30 located on the side of the grip portion 21 away from the main body assembly 10 along the first direction. The first direction is the direction in which the handle assembly 20 points to the main body assembly 10.

[0055] The dust collector provided by the embodiments of the present disclosure includes a main body assembly 10, a handle assembly 20, and a power assembly 30. The handle assembly 20 includes a holding portion 21, and the holding portion 21 is connected to the main body assembly 10. The power assembly 30 is arranged on the upper side of the handle assembly 20. The power assembly 30 includes a front portion 31 and a rear portion 32. The volume of the rear portion 32 is greater than the volume of the front portion 31. Thus, the weight of the main body assembly 10 can be balanced by the power assembly 30 to at least some extent, so that the center of gravity of the dust collector is close to the holding portion 21. Thus, the problem that the dust collector is prone to forward tilting when being held can be at least partially solved, and the problem that the user is prone to fatigue after long-time use of the dust collector can be solved.

[0056] The parts of the dust collector provided by the embodiments of the present disclosure will be described in detail as follows.

[0057] As shown in Figure 3 , the main body assembly 10 can include a main housing 11, a filter screen 12, a dust collector 13, and a suction port 14. The main housing 11 has a receiving space therein. The suction port 14 is arranged on the main housing 11, and a suction passage is formed between the suction port 14 and the power assembly 30. The filter screen 12 is arranged in the suction passage, and is used to filter the airflow sucked by the power assembly 30. The dust collector 13 can be arranged at the bottom of the filter screen 12, and is used to collect the dust, hair, and particles and other garbage sucked into the dust collector.

[0058] For example, the main body assembly 10 has a first axis in a third direction (Z direction, the direction in which the handle assembly 20 points to the power assembly 30). The filter screen 12 and the dust collector 13 are arranged along the first axis. The filter screen 12 is arranged above the dust collector 13. The dust collector 13 can be a passive dust collector 13, which collects the dust and garbage intercepted by the filter screen through the action of gravity. Alternatively, the dust collector 13 can also be an active dust collector 13 (for example, a cyclone dust collector 13), which collects the dust and garbage intercepted by the filter screen through suction or vibration.

[0059] The handle assembly 20 is connected to the main body assembly 10, and is used to provide a structure for the user to hold when the dust collector is used. For example, the handle assembly 20 can include a holding portion 21, and the user holds the dust collector through the holding portion 21 when the dust collector is used. That is, when the user holds the dust collector, the weight of the dust collector is borne by the holding portion 21. When the center of gravity of the dust collector is not reasonably arranged, the user is more laborious when using the dust collector, and is prone to fatigue after long-time use.

[0060] In some embodiments, as Figure 4 and Figure 5As shown, the handle assembly 20 can further include a first connecting portion 22, a second connecting portion 23, and a supporting portion 24. The first connecting portion 22 is connected to the main body assembly 10. One end of the second connecting portion 23 is connected to the bottom of the first connecting portion 22, and the other end of the second connecting portion 23 extends away from the main body assembly 10 and is connected to the holding portion 21, so as to form a holding space between the holding portion 21 and the first connecting portion 22. The supporting portion 24 is arranged at one end of the holding portion 21 away from the second connecting portion 23, and is used to support the power assembly 30.

[0061] The first connecting portion 22 is connected to the main body assembly 10, and there is a space between the first connecting portion 22 and the holding portion 21. The second connecting portion 23 is arranged between the holding portion 21 and the first connecting portion 22, and two ends of the second connecting portion 23 are respectively connected to the first connecting portion 22 and the holding portion 21. The second connecting portion 23 can be arranged at the lower end of the holding portion 21. The first connecting portion 22, the holding portion 21, and the second connecting portion 23 form a holding space in which the user's fingers are at least partially located when holding the vacuum cleaner. The first connecting portion 22, the second connecting portion 23, and the holding portion 21 can have a hollow structure, which can reduce the weight of the vacuum cleaner, reduce the amount of material used, and reduce production costs.

[0062] The supporting portion 24 is arranged at the top of the holding portion 21 and is used to support the power assembly 30. The supporting portion 24 is connected to the first connecting portion 22 and the holding portion 21, respectively, so that the strength of the handle assembly 20 can also be increased by the supporting portion 24. One end of the supporting portion 24 away from the first connecting portion 22 protrudes from the holding portion 21, so as to increase the supporting area and improve the installation stability of the power assembly 30. For example, the supporting portion 24 can have a circular arc plate shape, and the top surface of the supporting plate can form an arc-shaped groove in which the power assembly 30 is arranged.

[0063] In some embodiments, in order to improve the structural strength and installation convenience of the vacuum cleaner, the handle assembly 20 can further include a fixing portion 25 arranged at one side of the first connecting portion 22 away from the holding portion 21, and the fixing portion 25 is used to connect the main body assembly 10.

[0064] The fixing portion 25 is used to fix the filter screen and the dust collector 13, and the filter screen and the dust collector 13 are arranged at two sides of the fixing portion 25, respectively. The fixing portion 25 is provided with a hollow structure. For example, the filter screen is arranged at the upper side of the fixing portion 25, and the dust collector 13 is arranged at the lower side of the fixing portion 25. The fixing portion 25 can have a ring shape or an approximately ring shape, and the hollow structure on the fixing portion 25 can allow the gas passing through the dust collector 13 to enter the filter screen.

[0065] The fixed part 25 and the first connecting part 22 can be an integrally formed structure, for example, the fixed part 25 and the first connecting part 22 are formed by injection molding. Integrally forming the fixed part 25 and the first connecting part 22 can improve the connection strength of the fixed part 25, thereby improving the installation stability of the filter screen and the dust collector 13.

[0066] The end of the second connecting part 23 away from the main body assembly 10 does not exceed the holding part 21. That is, the end of the second connecting part 23 away from the main body assembly 10 is cut off at the holding part 21. By setting the end of the second connecting part 23 away from the main body assembly 10 to not exceed the holding part 21, the weight of the dust collector can be reduced, and the portability of the dust collector can be improved.

[0067] Further, an inclined transition part 26 is arranged between the end of the second connecting part 23 away from the main body assembly 10 and the holding part 21. The inclined transition part 26 can be a chamfer or a round corner. By arranging the inclined transition part 26 between the second connecting part 23 and the holding part 21, the weight of the dust collector can be further reduced. Moreover, the inclined transition part 26 can also improve the safety of the dust collector when in use.

[0068] The power assembly 30 is connected to the main body assembly 10, and the power assembly 30 is a device for providing suction power on the dust collector. For example, the power assembly 30 can include a power shell, a battery 302, and a fan 301. The power shell has a receiving space arranged therein, the battery 302 and the fan 301 are arranged in the power shell, the battery 302 and the fan 301 are electrically connected, and the battery 302 is used to provide electric energy to the fan 301. The fan 301 is used to form a negative pressure, thereby performing dust collection. The power shell is provided with an opening, and the opening of the power shell is in communication with the space in the main shell 11.

[0069] The power assembly 30 includes a front part 31 and a rear part 32, and the volume of the rear part 32 is greater than the volume of the front part 31. For example, the power shell can be a hollow cylinder or an approximately hollow cylindrical structure. The volume of the rear part 32 of the power shell is greater than the volume of the front part 31 of the power shell.

[0070] It should be noted that the boundary between the front part 31 and the rear part 32 of the power assembly 30 in the embodiment of the present disclosure can be the holding axis 211 of the holding part 21. The part of the power assembly 30 located on the holding axis 211 close to the main body assembly 10 is the front part 31, and the part of the power assembly 30 located on the holding axis 211 away from the main body assembly 10 is the rear part 32.

[0071] In one feasible embodiment, the center of gravity of the power assembly 30 along the first direction is positioned on the side of the grip 21 opposite to the main body assembly 10. By positioning the center of gravity of the power assembly 30 on the side of the grip 21 opposite to the main body assembly 10, the weight of the main body assembly 10 is balanced using the power assembly 30, thereby avoiding the problem of the vacuum cleaner's center of gravity being too forward, which would cause difficulty in use. For example, the weight of the rear part 32 is greater than the weight of the front part 31. The greater weight of the rear part 32 than the front part 31 allows the center of gravity of the power assembly 30 to be located at the rear end of the grip 21.

[0072] In another feasible embodiment, the power assembly 30 is arranged along a first direction (X direction), and the length of the rear portion 32 along the first direction is greater than the length of the front portion 31 along the first direction. The greater length of the rear portion 32 along the first direction allows the center of gravity of the power assembly 30 to shift rearward, thereby improving the balance of the vacuum cleaner during use.

[0073] For example, such as Figure 6 As shown, at least a portion of the fan 301 is disposed at the front 31, and at least a portion of the battery 302 is disposed at the rear 32. The length of the battery 302 along the first direction is greater than the length of the fan 301 along the first direction, and the weight of the battery 302 is greater than the weight of the fan 301. By placing the fan 301 at the front end and the battery 302 at the rear end, the center of gravity of the power component 30 is shifted to the rear, which helps to improve the balance of the vacuum cleaner during use.

[0074] The battery 302 and the fan 301 are spaced apart by a preset interval, the width of which is 1mm-10mm. For example, the width of the preset interval can be 1mm, 2mm, 3mm, 5mm, 8mm, 9mm, or 10mm. The width of the preset interval refers to the distance between the fan 301 and the battery 302 along the first direction.

[0075] The grip portion 21 extends along a second direction (P direction) and has a grip axis 211 along the second direction. The extension of the grip axis 211 intersects the fan 301. The battery 302 is located on the side of the grip axis 211 away from the main body assembly 10, and there is a gap between the battery 302 and the grip axis 211.

[0076] In some embodiments, the holding portion 21 has a partially overlapping area with the battery 302 near one end of the power assembly 30. The projection of the holding portion 21 on the power assembly 30 in the third direction near one end of the power assembly 30 is a first projection, the first projection and the battery 302 have a first overlapping area S1, the length of the first overlapping area S1 in the first direction is L1, the length of the battery 302 in the first direction is L2, and the ratio of L1 and L2 ranges from 0 to 0.3. For example, the ratio of L1 and L2 can be 0.01, 0.02, 0.05, 0.06, 0.07, 0.08, 0.1, 0.15, 0.2 or 0.3, etc.

[0077] By setting the ratio of L1 and L2 to be 0-0.3, on the one hand, the ratio of L1 and L2 is less than 0.3, which effectively controls the overlapping area of the battery 302 and the holding portion 21, thereby ensuring the distance between the center of gravity of the battery 302 and the holding portion 21, avoiding the problem that the center of gravity of the battery 302 is too close to the holding portion 21, resulting in poor effect of balancing the weight of the main assembly 10 by the battery 302; on the other hand, the ratio of L1 and L2 is greater than 0, which can effectively improve the supporting ability of the holding portion 21 to the power assembly 30 and improve the stability of the structure of the dust collector.

[0078] In some embodiments, the first projection and the battery 302 have no overlapping area. The first projection is located on the front side of the battery 302, that is, the supporting point of the holding portion 21 to the power assembly 30 is located in front of the battery 302. By setting the supporting point of the holding portion 21 to the power assembly 30 in front of the battery 302, the center of gravity of the battery 302 is located on the rear side of the supporting point, thereby improving the balancing ability of the battery 302 to the weight of the main assembly 10.

[0079] The extension direction of the holding portion 21 and the third direction have an included angle, and the distance between the holding portion 21 and the main assembly 10 increases in a direction away from the power assembly 30. That is, the holding portion 21 and the third direction are inclinedly arranged, and the inclined arrangement of the holding portion 21 can improve the convenience of the user holding the dust collector.

[0080] For example, the included angle between the second direction in which the holding portion 21 extends and the first direction is 60-80 degrees. For example, the included angle between the second direction and the first direction can be 60 degrees, 65 degrees, 70 degrees, 73 degrees, 75 degrees, 78 degrees or 80 degrees, etc. By setting the included angle between the second direction and the first direction to be 60-80 degrees, the center of gravity of the dust collector can be centered, it is more labor-saving when holding, and the inclination of the holding portion 21 is ensured, thereby improving the convenience of holding.

[0081] The holding portion 21 is obliquely arranged in the third direction, so the projections of the two ends of the holding portion 21 on the power assembly 30 in the third direction do not coincide. The projection of the end of the holding portion 21 away from the power assembly 30 on the power assembly 30 in the third direction is a second projection area, and in the first direction, the second projection area is within the range of the battery 302. The distance between the second projection area and the end of the battery 302 away from the main body assembly 10 in the first direction is L3, and the ratio of L3 to L2 is in the range of 0.3-0.6. For example, the ratio of L3 to L2 can be 0.3, 0.4, 0.5, or 0.6, etc.

[0082] By setting the ratio of L3 to L2 to be in the range of 0.3-0.6, on the one hand, the ratio of L3 to L2 is less than 0.6, which can make the center of gravity of the battery 302 located on the side of the holding portion 21 away from the main body assembly 10, avoiding the excessive weight of the battery 302 concentrated on the side of the holding portion 21 close to the main body assembly 10, which is beneficial to improve the balance of the holding of the vacuum cleaner, and on the other hand, the ratio of L3 to L2 is greater than 0.3, which is beneficial to control the obliquity of the holding portion 21 and improve the holding comfort.

[0083] In some embodiments, the center of gravity of the vacuum cleaner is configured to be located between the main body assembly 10 and the holding portion 21. The center of gravity of the holding portion 21 is located between the main body assembly 10 and the holding portion 21, which not only ensures that the center of gravity of the vacuum cleaner is close to the holding portion 21, making the use comfortable and labor-saving, but also avoids the problem that the center of gravity of the vacuum cleaner is located on the side of the holding portion 21 away from the main body assembly 10, causing the vacuum cleaner to have a tendency to fall backward when in use, which is inconvenient to use.

[0084] The power assembly 30 and the main body assembly 10 are detachably connected, so that the disassembly and maintenance of the power assembly 30 are convenient, and the power assembly 30 can also be used for other equipment (such as a scrubber). In order to disassemble the power assembly 30, the vacuum cleaner provided by the embodiment of the present disclosure can further include a disassembly button, which is arranged between the main body assembly 10 and the holding portion 21. The disassembly button is configured to be responsive to a pressing operation to release the connection between the power assembly 30 and the handle assembly 20, and the center of gravity of the vacuum cleaner is configured to be located between the disassembly button and the holding portion 21.

[0085] The disassembly button can have a first state and a second state, and the disassembly assembly is configured to switch between the first state and the second state in response to a pressing operation. When the disassembly button is in the first state, the disassembly button clamps the power assembly 30 to the handle assembly 20, and when the disassembly button is in the second state, the disassembly button releases the power assembly 30.

[0086] It should be noted that the center of gravity of the vacuum cleaner is located between the disassembly button and the holding portion 21 in the embodiment of the present disclosure, which means that the disassembly button, the center of gravity, and the holding portion 21 are arranged in sequence in the first direction. The heights of the disassembly button, the center of gravity, and the holding portion 21 in the third direction can be the same or different.

[0087] The dust collector provided by the embodiments of the present disclosure includes a main body assembly 10, a handle assembly 20, and a power assembly 30.
