Specifically, the motor unit 2 is located in the middle region of the housing 1, and the axis of the motor unit 2 may be substantially in the vertical direction, i.e., perpendicular to the upper end face 15 and the lower end face 16 of the housing 1, or may be substantially in the horizontal direction, i.e., perpendicular to the third side wall 13 and the fourth side wall 14 of the housing 1, so that there may be a space in the circumferential direction of the motor unit 2 to install other components. The motor unit that sets up in casing 1 can adopt brush motor, also can adopt brushless motor, and the accommodation space in casing 1 can be enough to hold any above-mentioned motor.

A dirt cup 3 is removably mounted to the housing 1 for collecting the entrained particles. As shown in fig. 1 to 3, while the axis of the motor unit 2 may be substantially in the vertical direction, the axis of the dirt cup 3 is also substantially in the vertical direction, i.e., perpendicular to the upper end surface 15 and the lower end surface 16 of the housing 1, so that the axis of the motor unit 2 and the axis of the dirt cup 3 are parallel to each other. Similarly, when the axis of the motor unit 2 is in the horizontal direction, the axis of the dirt cup 3 is also in the substantially horizontal direction. The motor unit may comprise a fan, the dirt cup comprises a cross-section which may have various aspects, for example approximately circular, square or rectangular, etc., and the ratio of the diameter of the fan to the diameter or length or width of the dirt cup may be controlled to be in the range of 0.7: 1-0.9: 1.

In addition, the horizontal cross section of the dust cup 3 can be approximately the same shape as the lower end surface 16 of the housing 1, so that the lower end surface 16 of the housing 1 is provided with the whole dust cup 3, the volume of the dust cup 3 is maximized, and the volume of the whole dust collector can be optimized, and further, the dust collector is miniaturized.

Fig. 7 is a schematic structural diagram of a dust dumping button and a dust dumping cover of a dust collector in an embodiment of the invention in one section, fig. 8 is a schematic structural diagram of a dust dumping button and a dust dumping cover of a dust collector in an embodiment of the invention in another section, as shown in fig. 7 and 8, the dust cup 3 may include a dust dumping cover 22 located below the lower end surface 16 and a buckle 21 locking the dust dumping cover 22, the dust collector may include a dust dumping button 19 controlling the dust dumping cover 22 to be opened, and the dust dumping button 19 is arranged on the upper end surface 15. Specifically, the dust collector can comprise an intermediate rod 20 positioned between the dust dumping button 19 and the dust dumping cover 22, one end of the intermediate rod 20 is fixedly connected with the dust dumping button 19, the other end of the intermediate rod 20 corresponds to the position of the buckle 21, and under the action of the dust dumping button 19, the intermediate rod 20 can be abutted against the buckle 21 to control the opening of the dust dumping cover 22.

As shown in fig. 1, the battery 4 is disposed on the side of the case 1. Since the housing 1 may have a substantially rectangular parallelepiped shape, the first side wall 11 of the housing 1 is formed with a recess in which the battery 4 is mounted, the battery 4 being parallel to the axis of the motor unit 2. The direction of insertion of the batteries 4 can be parallel to the axis of the motor unit 2, and in a possible embodiment the batteries 4 can be inserted from the lower end face 16 in the direction of the upper end face 15. In a preferred embodiment, the cross section of the recess in the direction of the first side wall 11 may be similar to the shape of the first side wall 11, and may be rectangular or square, and the overall shape of the battery 4 is similar to the recess, so that the battery 4 can be mounted in the recess under the condition of maximum size, and the space at the first side wall 11 of the whole housing 1 is not wasted. The depth of the whole concave part is small, and the cross section of the concave part in the direction of the first side wall 11 is large, so that the length of the shell 1 in the direction vertical to the first side wall 11 is relatively small, and the miniaturization of the dust collector is facilitated.

As shown in fig. 1 to 3, the cleaner may include: the suction pipe unit 5 comprises a hose 51 and a hard pipe 52, and a pipe groove unit 22 capable of accommodating the suction pipe unit 5 is formed on the shell 1 or in the shell 1. When the cleaner is to be used, the suction pipe unit 5 can be removed from the housing 1, and when the cleaner is used or stored for transportation, the suction pipe unit 5 can be mounted on the pipe groove unit 22 of the housing 1, so that the cleaner enters a storage state, and at the moment, the suction pipe unit 2 at least partially surrounds the upper end surface, namely, the suction pipe unit 5 extends from the suction inlet on one side of the dust cup 3 to the handle 17 and extends to the other side of the dust cup 3 along the length direction of the handle 17. Through the mode, the parts of the whole dust collector can be arranged together, the whole dust collector is miniaturized, and meanwhile, the omission of the parts can be prevented and the storage and the carrying of the dust collector are facilitated.

In one possible embodiment, as shown in fig. 1 to 3, the chase unit 22 may include: a first pipe groove 131 formed on the third side wall 13, and a second pipe groove 141 formed on the fourth side wall 14, wherein one end of the straw unit 5 can be clamped in the first pipe groove 131, the other end of the straw unit 5 can be clamped in the second pipe groove 141, and the middle of the straw unit 5 is wound around the upper end surface 15. The first pipe groove 131 extends substantially in the vertical direction, is located substantially in the middle of the third side wall 13, where there is no recess for mounting the battery 4, and there is enough space on the housing 1 to open the first pipe groove 131; similarly, the second pipe groove 141 extends substantially in the vertical direction, and is located substantially in the middle of the fourth side wall 14. When the straw unit 5 needs to be stored, one end of the pipe groove unit 22 is clamped in the first pipe groove 131, the other end of the pipe groove unit 22 can be clamped in the second pipe groove 141, and two ends of the pipe groove unit 22 are clamped and fixed; the middle of the duct unit 22 is wound around the upper end surface 15, so that the entire duct unit 22 can be accommodated in the housing 1.

Since the suction pipe units 5 generally include the flexible pipe 51 and the hard pipe 52 for the user to hold, the hard pipe 52 cannot be bent, and therefore, the hard pipe 52 is caught in the first pipe groove 131 extending in a straight line. The hose 51 can be bent at will so that the hose 51 runs round the upper end surface 15 and the corners between the different surfaces. Of course, the hose 51 and the wand 52 of the straw unit 5 may be connected together.

In a possible embodiment, as shown in fig. 1 to 3, a handle 17 may be formed on the upper end surface 15 of the housing 1, the handle 17 may be substantially in the shape of an inverted U or a circular arc, and a gap is provided between the handle 17 and the main body of the housing 1, and when a user grips the housing, fingers are inserted into the gap to grip the handle 17. A third tube groove 171 is formed on the side of the handle 17 facing away from the housing 1. One end of the third pipe groove 171 may be connected to the first pipe groove 131, the other end of the third pipe groove 171 may be connected to the second pipe groove 141, and the middle portion of the pipette unit 5 may be engaged in the third pipe groove 171. In order to better position the middle of the suction unit 5 (i.e. the part that bypasses the upper end surface 15 of the housing 1) and to facilitate the user's pick-up of the cleaner. In the above manner, the portion of the third groove 171 has a curvature, and the portion of the hose 51 in the middle of the suction unit 5 can be locked in the third groove 171 for positioning, without affecting the user's pick-up of the cleaner.

In a possible embodiment, as shown in fig. 3, one end of the hose 51 can be at least partially retracted in the rigid tube 52, so that the space inside the rigid tube 52 can also store part of the hose 51, which can allow the length of the hose 51 to be further increased if the housing 1 is of the same size. When the suction unit 5 is used, the hose 51 is drawn out of the wand 52, maximising the length of the hose 51.

In a possible embodiment, fig. 5 is a schematic view showing a structure of a connection portion of the hose and the fixing pipe in fig. 3, and fig. 6 is a schematic view showing an end of the hose at the connection portion of the hose and the fixing pipe in fig. 3, and as shown in fig. 5 and 6, the cleaner may include: a fixed pipe 6 installed at the suction inlet of the dust cup 3, and the other end of the hose 51 is detachably connected with the fixed pipe 6 and can rotate between the two; the end of the other end of the hose 51 is connected with a hard connecting piece 511, the outer side wall of the connecting piece 511 is provided with a fixing ring 512 with a notch, the connecting piece 511 can rotate relative to the fixing ring 512, the outer side wall of the fixing ring 512 is provided with a buckling part 5121, and the inner side wall of the fixing pipe 6 is provided with a clamping groove 62 matched with the buckling part 5121. After the fixing ring 512 of the flexible tube 51 is inserted into the fixing tube 6, the buckling part 5121 is embedded into the clamping groove 62, so that the flexible tube 51 is detachably connected with the fixing tube 6. In order to ensure airtightness between the fixing ring 512 of the hose 51 and the fixing tube 6, a sealing ring 61 may be provided between the fixing ring 512 and the fixing tube 6. The fixing ring 512 is provided with a gap, so that the fixing ring 512 is loosely sleeved on the connecting piece 511, and thus the connecting piece 511 can rotate relative to the fixing ring 512 and/or the fixing tube 6 to a certain extent, and the problems that the hose 51 is knotted and wound together when a user uses the hose are prevented.

In a possible embodiment, in order to prevent the hard tube 52 from being freely separated from the first tube groove 131 when the hard tube 52 is received in the first tube groove 131 of the housing 1, fig. 4 is an enlarged structural view of a portion a in fig. 3, as shown in fig. 4, a magnet 132 may be disposed at the first tube groove 131 of the third sidewall 13, and an attracted member 53 may be disposed at one end of the straw unit 5, for example, an attracted member 53 may be disposed on the hard tube 52, and when one end of the straw unit 5, such as the hard tube 52, is received in the first tube groove 131, the magnet 132 attracts the attracted member 53. The attracted member 53 may be made of a metal having an attracting ferromagnetic substance such as iron, nickel, cobalt, or the like, or may be another magnet. The interior of the hard tube 52 can be provided with a connecting tube 521 with screw threads for connecting other suction heads, and the attracted part 53 can be clamped between the outer wall of the connecting tube 521 and the inner wall of the hard tube 52. In this way, when the user needs to take the hard tube 52 out of the first tube groove 131 of the housing 1, the hard tube can be taken out with a little force.

As shown in fig. 1 and 2, when the axis of the motor unit 2 extends in the vertical direction, an accessory receiving groove 18 is formed on the housing 1 or in the housing 1, and the accessory receiving groove 18 is formed on the housing 1 between the motor unit 2 and at least one side wall of the housing 1. Preferably, at least one of both sides between the motor unit 2 and the second side wall 12 is formed with an accessory receiving groove 18.
