Preferably, the second locking assembly comprises a transverse locking tongue 7 positioned on one side of the power module 200 and a locking hole 8 positioned on one side of the power module 200, and the locking tongue 7 can extend into the locking hole 8 to realize vertical locking.

It should be understood that an elastic member is provided in the latch 7 so that the latch 7 can be extended or retracted toward the lock hole 8 side. In addition, the second locking assembly further comprises a control button 9, and the bolt 7 can be retracted by pressing the control button 9. Preferably, the control button 9 is provided between the bottom and the lateral portion 02 of the power module 200. A notch D is provided on the bottom of the lateral portion 02 near the outer side so that a user can press the control button 9 provided on the power module 200 from the notch D.

When the power module 200 is installed, the control button 9 is pressed to enable the bolt 7 to return, the power module 200 can move from bottom to top along the handheld assembly 300, the control button 9 is loosened to continue moving the power module 200 upwards until the bolt 7 meets the lock hole 8 and extends into the lock hole 8, at the moment, the inserting piece 6 is also inserted into the inserting hole 61, and therefore the power module 200 is positioned in the horizontal and vertical directions, and the connection is more stable and reliable. And the locking mechanism plays a role in positioning and supporting the power module 200 in the transverse and vertical directions, so that the installation is faster and more convenient, the force of the installed connection is concentrated on the locking mechanism, the electric connection end assembly is prevented from being deformed and damaged due to stress, and the problem of poor contact is avoided.

Further optimally, be equipped with location structure between power module 200 and the play dryer 30, location structure include the arc bulge structure E1 of power module 200 up end and the arc structure E2 of recessing of the downside of play dryer 30. Through the positioning of the positioning structure, the connection of the power module 200 is more stable. And the structure of the whole dust collecting equipment is more compact, the occupied volume is reduced, and the use is easier and more flexible.

In addition, in order to facilitate charging by the user, a charging interface Z is provided at a side portion of the power module 200. Therefore, the power module 200 can be charged when being installed on the host, and does not need to be detached, so that the use convenience of the dust collection equipment is further improved.

It is right above the utility model provides a hand-held type dust collecting equipment and power layout structure introduces in detail, and it is right to have used specific individual example herein the utility model discloses a principle and implementation mode have been explained, and the explanation of above embodiment is only used for helping to understand the utility model discloses and core thought. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
