As shown in fig. 1, the battery 4 is provided on the side of the case 1. Since the housing 1 may have a substantially rectangular parallelepiped shape, a recess is formed in the first side wall 11 of the housing 1, and the battery 4 is mounted in the recess, with the battery 4 being parallel to the axis of the motor unit 2. The plugging direction of the battery 4 may be parallel to the axis of the motor unit 2, and in a possible embodiment the battery 4 may be plugged from the lower end face 16 towards 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, may be rectangular or square, and the overall shape of the battery 4 may be similar to the recess, so that the battery 4 may be mounted in the recess with maximization, 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 smaller, and the cross section of the concave part in the direction of the first side wall 11 is larger, so that the length of the shell 1 in the direction vertical to the first side wall 11 is relatively smaller, 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 including the hose 51 and the hard pipe 52 is formed with a pipe groove unit 23 capable of accommodating the suction pipe unit 5 on the housing 1 or in the housing 1. When the cleaner is required to be used, the suction pipe unit 5 can be removed from the shell 1, and when the cleaner is used or stored and carried, the suction pipe unit 5 can be mounted at the pipe groove unit 23 of the shell 1, so that the cleaner enters a storage state, and at this time, the upper end face is at least partially bypassed by the 2 suction pipe unit, namely, the suction pipe unit 5 extends from the suction inlet on one side of the dust cup 3 to pass through the handle 17 and extends to the other side of the dust cup 3 along the length direction of the handle 17. By the mode, parts of the whole dust collector can be installed and placed together, the dust collector is miniaturized, omission of the parts can be prevented, and the dust collector is convenient to store and transport.

Since the suction pipe unit 5 generally includes the hose 51 and the hard pipe 52 for the user to hold, the hard pipe 52 cannot be bent, and thus 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 bypasses the upper end face 15 and the corners between the different faces. Of course, the hose 51 and the hard tube 52 of the suction pipe unit 5 may be connected together.

In the above manner, the portion of the third tube groove 171 has a curvature, and the hose 51 portion in the middle of the suction tube unit 5 can be caught in the third tube groove 171 for positioning, without affecting the user's holding up the cleaner.

In a possible embodiment, as shown in fig. 3, one end of the hose 51 is at least partially retractable in the hard tube 52, so that the space in the hard tube 52 can also store part of the hose 51, and the length of the hose 51 can be further increased on the premise of the same size of the housing 1. When the suction pipe unit 5 is used, the hose 51 is drawn out of the hard pipe 52, and the length of the hose 51 is maximized.

In one possible embodiment, fig. 5 is a schematic structural view of the connection between the hose and the fixing tube in fig. 3, and fig. 6 is a schematic view of one end of the hose at the connection between the hose and the fixing tube 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, the other end of the hose 51 being detachably connected to the fixed pipe 6 and rotatable therebetween; 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 clamping part 5121, and the inner side wall of the fixing tube 6 is provided with a clamping groove 62 matched with the clamping part 5121.

In order to ensure air tightness 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 notch, so that the fixing ring 512 is sleeved on the connecting piece 511 more loosely, the connecting piece 511 can rotate to a certain extent relative to the fixing ring 512 and/or the fixing tube 6, and further the problems that the hose 51 is knotted, wound together and the like can be prevented when a user uses the hose.

In one possible embodiment, in order to prevent the hard tube 52 from being randomly 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 schematic view of a structure at a in fig. 3, and as shown in fig. 4, a magnet 132 may be provided at the first tube groove 131 of the third sidewall 13, an attracted piece 53 may be provided at one end of the suction tube unit 5, for example, an attracted piece 53 may be provided at the hard tube 52, and the magnet 132 attracts the attracted piece 53 when one end of the suction tube unit 5, such as the hard tube 52, is received in the first tube groove 131.

In this way, when the user needs to take out the hard tube 52 from the first tube groove 131 of the housing 1, the hard tube 52 can be taken out with little effort.

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 between the motor unit 2 and at least one side wall of the housing 1 on the housing 1. Preferably, an accessory receiving groove 18 is formed in at least one of both sides between the motor unit 2 and the second side wall 12.
