So set up, make things convenient for battery 4 to charge, and be convenient for be applied to battery 4 on other matched electric tool or the dust catcher uses other electric tool's that can match battery 4, promptly, can many machines sharing a battery 4, practiced thrift the cost. The battery 4 is arranged to slide from the lower end face 16 to the upper end face 15, so that the upper end face 15 of the dust collector is more conveniently arranged to be a complete plane, and if the battery 4 is inserted from the upper end face 15 to the lower end face 16 in a sliding manner, a gap is formed in the upper surface of the whole machine, and the integrity of the machine is damaged.

In the above embodiments, the battery 4 is vertically exposed out of the casing 1, and in other embodiments, the battery 4 may be horizontally disposed at different positions of the vacuum cleaner, or may be vertically exposed out of other positions of the casing 1.

As shown in fig. 1, 6 and 12, the vacuum cleaner has a recessed portion 111, the battery 4 is accommodated in the recessed portion 111, and an axis X3 of the battery 4 is parallel to an axis X1 of the motor unit 2. The recessed portion 111 includes a first recessed portion and a second recessed portion, the first recessed portion is formed in the housing 1, and the first recessed portion is formed by the housing 1 being recessed inward from the first side wall 11. The second concave part is formed on the dust cup, and the second concave part is formed by inwards concave arrangement of the outer wall of the dust cup 3. The motor unit 2 and the dust cup 3 together form a housing cavity for housing the battery 4, which is the recess 111. The housing 1 may be substantially rectangular parallelepiped in shape. The concave portion 111 does not penetrate the upper end surface 15 of the housing 1, the concave portion 111 is located below the upper end surface, the concave portion 111 has a top portion 112, the upper surface of the top portion 112 is the upper end surface 15 of the housing 1, and the upper end surface 15 of the housing 1 is a complete surface without any gap when viewed as a whole. In a preferred embodiment, the cross section of the recess 111 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 111, so that the battery 4 can be installed in the recess 111 under the condition of maximum, and the space at the first side wall 11 of the whole casing 1 is not wasted. The depth of the whole recess 111 is small, and the cross section of the recess 111 in the direction of the first side wall 11 is large, so that the length of the housing 1 in the direction perpendicular to the first side wall 11 is relatively small, which facilitates the miniaturization of the cleaner.

In one embodiment, as shown in fig. 4, fig. 13 and fig. 14, the housing 1 is a square or square-like structure, the corners of two adjacent side walls of the housing are provided with round corners, the dust cup 3 is mounted under the housing 1 and has a shape matching the housing 1, the dust cup 3 has a dust collecting and separating chamber therein for collecting dust and separating dust particles, and the dust collecting and separating chamber is circular or circular-like (non-square), and the shape is designed such that the housing 1 can have a mounting space for the battery 4 without increasing the size of the structure, and the housing 1 and the dust cup 3 can also have a receiving groove 18 (described later) for receiving the accessory 200.

As shown in fig. 1 and 5, the vacuum cleaner may comprise a suction unit 5, the suction unit 5 further comprising a hose 51 and a wand 52, the vacuum cleaner being provided with a hose-and-channel unit 22 which is capable of receiving the suction unit 5. When the dust collector needs to be used, the suction pipe unit 5 can be taken down from the shell 1, when the dust collector is used or stored and transported, the suction pipe unit 5 can be arranged at the pipe groove unit 22 of the shell 1, so that the dust collector enters a storage state, at the moment, the suction pipe unit 5 at least partially surrounds the upper end surface 15, namely, the suction pipe unit 5 extends from the suction opening 31 at one side of the dust cup 3 to the other side of the dust cup 3 along the length direction of the handle 17 to extend over the handle 17, and the tail end part of the suction pipe unit 5 is at least partially accommodated in the pipe groove unit 22. 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 and 5, the chase unit 22 may include: a first pipe groove 131 formed on the third sidewall 13, and a second pipe groove 141 formed on the fourth sidewall 14. 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 on the upper end face 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 pipette unit 5 needs to be stored, one end of the pipette unit 5 is clamped in the first pipe groove 131, the other end of the pipette unit 5 can be clamped in the second pipe groove 141, and the two ends of the pipette unit 5 are clamped and fixed; the central portion of the straw unit 5 is wound around the upper end surface 15, so that the whole straw unit 5 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 one embodiment, one end of the flexible tube 51 can be at least partially contracted in the hard tube 52, so as to ensure the required length of the flexible tube 51 in the use state, and also to store part of the flexible tube 51 when not in use, thereby ensuring the storage effect of the suction pipe unit 5 and further ensuring the miniaturization of the overall appearance layout.

In a possible embodiment, as shown in fig. 1 and 5, a handle 17 may be formed on the upper end surface 15 of the housing 1, the handle 17 may be substantially in an inverted U shape or a circular arc shape, and a gap is formed between the handle 17 and the main body of the housing 1, and when a user holds the handle, fingers are inserted into the gap so as to hold 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.
