[0058] Combination Figure 8 In some embodiments of the utility model, the first limiting portion 11 is arranged in the shell 10, and the shell 10 can protect the first limiting portion 11 to improve the structural stability of the power cord 20 after installation, and the shell 10 is provided with an installation opening 12, and the power cord 20 is passed through the installation opening 12. Exemplarily, the power cord 20 can be inserted into the shell 10 from the installation opening 12, and the second limiting portion 21 is positioned at the first limiting portion 11 along the first direction. Compared with the related art, the power cord 20 is installed by clamping the power cord 20 by two shells, which makes the installation of the power cord 20 convenient.

[0059] Combination Figure 1 and Fig.11 In some embodiments of the present invention, the housing 10 includes a first housing 15 and a second housing 16. The first direction is the direction in which the cleaning device 100 moves forward and backward when working. The first housing 15 and the second housing 16 are distributed along the first direction. A parting line 17 is formed at the connection between the first housing 15 and the second housing 16. The parting line 17 is located at the edge of the projection of the housing 10 along the first direction. Exemplarily, the first direction may be the front-to-back direction. When the user uses the cleaning device 100, the first housing 15 faces the user, and the second housing 16 faces away from the user. By arranging the parting line 17 at the edge of the projection of the housing 10 along the first direction, in other words, when the user uses the cleaning device 100, the parting line 17 is located at the edge of the housing 10 to avoid the parting line 17 being located on the front of the main body, so that the main body is beautiful as a whole and the user's experience is improved.

[0060] In the related art, the housing of the main machine must be split in half in the installation direction of the power cord 20 so that the housing can clamp the main power cord 20. After the main machine is assembled, it is on the front of the machine, resulting in a gap on the front of the machine after the main machine is assembled, which affects the appearance. Compared with the above-mentioned solutions in the related art, the parting line 17 of the cleaning device 100 of the utility model embodiment is located at the edge of the shell 10, which can reduce the exposure of the parting line 17 of the shell 10 to the front and improve the structural consistency of the shell 10.

[0061] In addition, combined Figure 1 and Figure 8The installation opening 12 may be located at the rear side of the housing 10 along the first direction. Specifically, along the first direction, the installation opening 12 is closer to the rear side of the housing 10 than the front side of the housing 10. Specifically, the power cord 20 extends from the installation opening 12, and the installation opening 12 is closer to the rear side of the housing 10. That is, the position where the power cord 20 extends is closer to the user, which can reduce the bending of the power cord 20 during use and increase the service life of the power cord 20. Fig. 9 In some embodiments of the utility model, the shell 10 is also provided with a first support rib 13, and the first support rib 13 is arranged on one side of the positioning portion 30 along the second direction. The first support rib 13 can position and limit the positioning portion 30, thereby improving the installation efficiency of the positioning portion 30 and the structural stability after installation, so that the positioning portion 30 can stably limit the power cord 20.

[0062] Furthermore, the shell 10 also includes a second support rib 14, which is arranged on two opposite sides of the positioning part 30 along the third direction. The third direction, the first direction and the second direction are perpendicular to each other. The second support member can position and limit the positioning part 30 in the third direction to further improve the installation efficiency and structural stability of the positioning part 30.

[0063] For example, in combination Figure 3 and Fig. 9 The positioning portion 30 can be a shock-absorbing structure of the motor. Along the second direction, one side of the positioning portion 30 abuts against the first supporting rib 13, and the other side can be supported on the motor; along the first direction, one side of the positioning portion 30 abuts against the second limiting portion 21, and the other side can be connected to the shell 10; along the third direction, both sides of the positioning portion 30 are connected to the two second supporting ribs 14 on both sides of the positioning portion 30. In this way, the second positioning portion 30 can be limited in the first direction, the second direction, and the third direction, and the third direction, the first direction, and the second direction are perpendicular to each other. The positioning portion 30 will not move in any direction, thereby improving the structural stability of the positioning portion 30 and effectively limiting the power cord 20.

[0064] Combination Figure 8 and Fig. 9In some embodiments of the present invention, the housing 10 includes a first housing 15 and a second housing 16, the first limiting portion 11 may be provided at the first housing 15, the first housing 15 and the second housing 16 are connected along a first direction, and the positioning portion 30 is limited between the first housing 15 and the second housing 16. Exemplarily, the first housing 15 may be a lower cover of the vacuum cleaner body, the second housing 16 may be an upper cover of the body, the first limiting portion 11 is provided at the first housing 15, in other words, the second limiting portion 21 of the power cord 20 is limited at the first housing 15. In the related art, the main housing must be divided into two halves in the installation direction of the power cord 20. During the assembly process, the power cord 20 needs to be placed in one housing first. When assembling the other half of the housing, there is a risk that the power cord 20 will fall out of the original housing, resulting in the assembly not being in place and pressing the wire, and the assembly method is complicated. In addition, 1-2 screws need to be placed near the power cord 20 to fix the power cord 20, which easily leads to a large gap in the position of fixing the power cord 20. Compared with the solutions in the above-mentioned related art, the power cord 20 in the embodiment of the utility model does not need to be pressed during installation, which simplifies the installation process of the power cord 20 and reduces the number of screws used.

[0065] Exemplary, combined Figures 1 to 9 The installation opening 12 can be provided on the first shell portion 15, and the first limiting portion 11 can also be provided on the first shell portion 15. When assembling the power cord 20, one end of the power cord 20 can be first installed into the first shell portion 15 from the installation opening 12, and then the second limiting portion 21 can be embedded into the first limiting portion 11 along the first direction. The first limiting portion 11 can limit the power cord 20 in both the second direction and the third direction, and then the positioning portion 30 is installed to the first shell portion 15 to limit the power cord 20 in the first direction. Finally, the second shell portion 16 is installed to the first shell portion 15 along the first direction. The installation structure of the power cord 20 is simple, and the first limiting portion 11, the second limiting portion 21 and the positioning portion 30 cooperate to improve the installation efficiency of the power cord 20 and the structural stability after installation.
