Fig. 1 is a schematic diagram of an internal structure of a garbage separator according to an embodiment of the present invention.

As shown in fig. 1, the waste separator 1 at least comprises: a dust barrel 11, a rotary separator 12 and an outer rotor motor 13. Wherein, be equipped with fluid entry 111 and fluid outlet 112 on the dirt bucket 11, rotatory separator 12 sets up in the inside of dirt bucket 11, and external rotor motor 13 includes rotor shell and motor shaft, and the external rotor sets up in the inside of rotatory separator 12, and rotor shell and rotatory separator 12 fixed connection, motor shaft and dirt bucket 11 fixed connection.

The working principle of the garbage separator 1 is as follows: the rotating separator 12 is driven by the outer rotor motor 13 to rotate, and the air is regularly stirred in the center of the dust barrel 11, so that the air flow in the dust barrel 11 forms an effect similar to cyclone, thereby separating the garbage carried in the fluid, and preventing large-particle solid garbage from passing through the rotating separator 12, thereby realizing the effect of effectively separating dust and air.

As in a general motor, the rotor housing of the external rotor motor 13 includes a stator assembly and a rotor assembly, wherein the rotor assembly is located outside the motor, and the stator assembly is located inside the motor. Thus, the outer side of the motor rotates and drives the object connected with the rotor shell to rotate together. Compare in the motor of current other structures, better leakproofness can be accomplished to external rotor electric machine 13 to avoid the dust to enter into inside the motor.

In some alternative embodiments, with continued reference to fig. 1, a first filter device 14 is also provided at the fluid outlet 112 of the dirt bucket 11. Then, the motor shaft of the external rotor motor 13 can be fixedly connected to the first filter device 14. For example, the motor shaft of the outer rotor motor 13 is provided with a screw thread, the first filtering device 14 is provided with a screw thread, the screw thread on the motor shaft is in threaded connection with the screw thread on the first filtering device 14, the first filtering device 14 is fixedly arranged at the fluid outlet 112, the outer rotor motor 13 is in threaded connection with the first filtering device 14 through the motor shaft to realize fixed connection relative to the dust barrel 11, and meanwhile, the rotor housing of the outer rotor motor 13 is fixedly connected with the top of the rotating separator 12 (below the rotating separator 12 in fig. 1), so that the outer rotor motor 13 can drive the rotating separator 12 to rotate through the rotor housing.

Fig. 2 is a schematic diagram of an internal structure of a rotating separator according to an embodiment of the present invention.

As shown in fig. 2, in some alternative embodiments, the rotating separator 12 is a hollow cylinder, the bottom of the cylinder (above the cylinder in fig. 2) is an opening corresponding to the position of the fluid outlet 112 of the dust bin 11, the top of the cylinder (below the cylinder in fig. 2) is a closed structure, for example, the top of the cylinder in fig. 2 is a closed plane, and the cylindrical surface of the cylinder (the side of the cylinder in fig. 2) is provided with a plurality of ventilation holes 121 penetrating through the cylinder. Wherein, in the inside of the cylinder, the top of the cylinder is provided with a groove 123 for placing the outer rotor motor 13, and the rotor housing of the outer rotor motor 13 is connected with the groove 123 in an interference fit manner, so as to realize the fixed connection of the outer rotor motor 13 and the rotary separator 12. Of course, in practice, the connection between the rotor housing and the groove 123 may also be an adhesion connection or other fixed connection, and the present invention does not limit the fixed connection between the outer rotor motor 13 and the rotating separator 12.

Specifically, with continued reference to fig. 2, the ventilation holes 121 on the side surface (i.e., cylindrical surface of the cylinder) of the rotating separator 12 are circumferentially arranged in an array in order from the bottom to the top of the rotating separator 12, and the ventilation holes 121 are distributed over the entire side surface of the rotating separator 12. Equivalently, from the bottom to the top of the rotating separator 12, the rotating separator includes a plurality of circles of ventilation holes 121 circumferentially arranged around the side of the rotating separator 12, the ventilation holes 121 are spaced and parallel, the ventilation holes 121 in each circle of ventilation holes 121 are also spaced and arranged to form an array structure, and the ventilation holes 121 are distributed over the whole or most of the side of the rotating separator 12.

Fig. 3 is a schematic side view of a rotary separator according to an embodiment of the present invention.

In some alternative embodiments, as shown in fig. 3, the difference from the above-described rotating separator 12 of fig. 2 is that: the ventilation holes 121 of the rotating separator 12 in this embodiment are arranged spirally along the side of the rotating separator 12 to form at least one spiral ventilation hole structure. For example, as shown in fig. 3, 4 turns of spiral vents are arranged on the side of the rotating separator 12. It should be understood that the pitch and the number of turns of the spiral vent holes formed by the spiral distribution of the vent holes 121 along the side of the rotating separator 12 may be determined according to the ventilation amount of the vacuum cleaner and the size of the rotating separator 12, and the present invention is not particularly limited thereto.

Specifically, with respect to the spiral vent holes in fig. 3, the respective vent holes 121 are arranged in an array between the spiral vent holes of the same turn or/and the spiral vent holes of different turns, thereby forming a regular vent structure on the side of the rotating separator 12. Compared with the vent hole structure arranged in an array in fig. 2, the spiral vent hole 121 in this embodiment can guide the fluid to enter the rotating separator 12 in a spiral shape, so that a cyclone effect is also formed inside the rotating separator 12, and therefore fine dust inside the rotating separator 12 is not easily adsorbed on the first filtering device 14 or the vent hole 121, and a situation that the suction force is reduced due to the blockage of the vent hole 121 or the first filtering device 14 by the dust after a long use time can be avoided.

Further, in addition to the rotating separator 12 provided in the above embodiment being a hollow cylindrical structure, in practical applications, the cyclone separator may also include a hollow conical or truncated cone structure. Similarly, when the rotating separator 12 is a hollow cone or a circular truncated cone, the bottom of the cone or the circular truncated cone is an opening, the opening corresponds to the position of the fluid outlet 112 of the dust bin 11, the top of the circular truncated cone is a closed plane, and a plurality of vent holes 121 penetrating through the cylinder are formed in the side surface of the cone or the circular truncated cone. Obviously, the rotating separator 12 may have different shapes such as a cylinder, a cone, and a truncated cone, and the structures of the opening and the vent hole 121 on the rotating separator 12 may be the same as those of the cylinder, so the details of the structure in which the rotating separator 12 is a hollow cone or a truncated cone are not described here.

Wherein, in some alternative embodiments, the shape of the vent 121 on the rotating separator 12 may include, but is not limited to, any one of a round hole, a square hole, or a triangular hole. The shape of the vent hole 121 is not particularly limited by the present invention.

Referring to fig. 1 again, in the dust separator 1, the fluid inlet 111 and the fluid outlet 112 on the dust bin 11 are disposed, as shown in fig. 1, the bottom of the rotating separator 12 (and the upper side of the rotating separator 12 in fig. 1) is open, the fluid outlet 112 on the dust bin 11 is disposed toward the bottom of the rotating separator 12, and the fluid inlet 111 is disposed toward the side of the rotating separator 12.

Furthermore, in some alternative embodiments, the fluid inlet 111 on the dirt cup 11 may also be disposed toward the top of the rotating separator 12 (e.g., below the rotating separator 12 in FIG. 1), and the centerline of the fluid inlet 111 is parallel to the rotational axis 122 of the rotating separator 12. Preferably, the centerline of the fluid inlet 111 may coincide with the rotational axis 122 of the rotating separator 12. The effect of this design is: the moving path of the fluid entering the dust separator 1 in the dust bin 11 is made as short as possible to reduce the pressure loss of the fluid in the dust bin 11, thereby improving the separation efficiency of the dust separator 1.

In summary, the garbage separator 1 provided by the utility model has the beneficial effects that: the outer rotor motor 13 is adopted to drive the rotary separator 12, so that the sealing performance of the motor can be realized, and fine dust is prevented from entering the motor in the rotating process of the motor; meanwhile, the rotor shell of the outer rotor motor 13 is fixedly installed on the rotary separator 12, and the diameter of the rotor shell is relatively large, so that the rotary separator 12 can be effectively prevented from shaking in the rotating process of the rotary separator 12, and the stability of the cyclone separator during operation is improved. Furthermore, the separation efficiency of the garbage separator 1 with respect to the garbage is also informed by optimizing the structure of the rotating separator 12 and the like.

Fig. 4 is a schematic view of the internal structure of the vacuum cleaner according to the embodiment of the present invention. As shown in fig. 4, the vacuum cleaner comprises the debris separator 1 of the embodiment shown in fig. 1, and further comprises: a fan housing 2. Wherein, the fan bin 2 is connected with the garbage separator 1. Specifically, the fan chamber 2 is connected to the fluid outlet 112 of the dust barrel 11, and the fan 21 and the second filtering device 22 are disposed in the fan chamber 2. When the vacuum cleaner is in operation, fluid entering the vacuum cleaner is discharged through the fluid inlet 111, the rotating separator 12, the first filter device 14, the fan 21 and the second filter device 22 in this order.

Specifically, the first filter device 14 and the second filter device 2 are air filters for filtering fine solid particles or odor gas, etc. in the fluid. In practice, the specific product types of the first filter device 14 and the second filter device 22 may be selected according to the needs of the application.

In particular, the connection between the waste separator 1 and the wind-mill silo 2 in fig. 4 comprises a detachable connection. For example, when the vacuum cleaner is used, the first filter device 14 may be replaced or cleaned by detaching the dust separator 1 from the blower chamber 2; and then, the garbage is separated and connected with the fan bin 2, and the garbage continues to be used for dust collection. In addition, as shown in fig. 4, a dust barrel cover 123 is further disposed on the barrel 11, the dust barrel cover 123 is rotatably connected to the dust barrel 11, and when the garbage in the garbage separator 1 is accumulated too much, the dust barrel cover 123 can be opened to clean the garbage collected in the dust barrel 11.

Further, with continued reference to fig. 4, the vacuum cleaner further comprises: the handle 3, the handle 3 is connected with the outside of the garbage separator 1 or the fan chamber 2, and a user can operate the vacuum cleaner to work by holding the handle 3. Specifically, the handle 3 may be connected to the outside of the garbage separator 1, the outside of the fan housing 2, or both the garbage separator 1 and the fan housing 2. Wherein the connection may include, but is not limited to, a detachable connection, a fixed connection, and the like.

In summary, the vacuum cleaner provided by the utility model has the beneficial effects that: by applying the above garbage separator to a vacuum cleaner, the durability of the existing vacuum cleaner and the efficiency of separating garbage can be further improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
