The voltage of the built-in battery of the existing handheld dust collector is different due to the difference of models, and the voltage range of the battery of the handheld dust collector is generally between 12 and 36V. Therefore, the corresponding charging voltage can be adapted according to the voltage of the handheld dust collector through the arrangement of the intelligent control circuit so as to adapt to the charging requirements of the handheld dust collectors of different models. In the intelligent control circuit, the serial port is a port connected with the charging contact piece 21, when the charging interface 121 of the handheld dust collector is in abutting contact with the charging contact piece 21, the serial port, the charging contact piece 21 and the charging interface 121 are electrically connected, and at the moment, the (battery) voltage information of the handheld dust collector can be transmitted to the serial port through the charging interface 121, namely, the voltage information at the serial port is consistent with the voltage information at the charging interface 121; then the voltage detection module transmits the detected voltage information at the serial port to the control module, and the control module perceives the voltage polarity and the voltage value and judges whether the reverse connection exists or not and what the voltage value is; then the control module controls the voltage regulating module to regulate the charging voltage so that the charging voltage output by the serial port is consistent with the voltage of the battery in the handheld dust collector.

In some embodiments, referring to fig. 4-5, the standing lock structure includes a housing 4, a lock assembly. The casing 4 is located right above the stand 23, and one side of the casing is provided with a locking slot 41 for accommodating the hand-held handle 12. The locking assembly is built in the casing 4 and comprises a driving piece and a locking piece 5, and the locking piece 5 can form a closed loop structure or an open loop structure with the locking groove 41 under the driving of the driving piece.

In the initial state, an open loop structure is formed between the locking piece 5 and the locking slot 41, when the handheld dust collector is placed on the bottom plate 22, the dust collection main body 11 can enter the limiting groove 221 under the guidance of the guiding rib plate 222 and can continue to move along the limiting groove 221 towards the vertical seat 23 until the charging interface 121 on the handheld handle 12 is abutted to the charging contact piece 21, and the handheld dust collector enters the charging state; then the upper end part of the hand-held handle 12 is pushed into the locking slot 41, the driving piece is started to enable the locking piece 5 to move, and a closed loop structure is formed between the driving piece and the locking slot 41 to lock the hand-held handle 12 positioned in the locking slot 41, and at the moment, the hand-held handle 12 can be stably kept standing under the common support of the locking slot 41 and the locking piece 5; when the hand-held dust collector is needed, the locking piece 5 is driven to move only through the driving piece, and an open loop structure is formed between the locking piece and the locking groove 41, and at the moment, the hand-held handle 12 can be separated from the locking groove 41; then, the handle rod 12 is held by the upper handle to drive the dust collection main body 11 to leave the limit groove 221.

In addition, in order to adapt to the cylindrical structure of the hand-held grip 12, in practical use, the locking groove 41 may be designed as a semicircular groove, and the inner diameter of the locking groove 41 may be set larger than the outer diameter of the hand-held grip 12; accordingly, the inner diameter of the locking piece is set to be identical to the inner diameter of the locking groove 41. Thus, the closed loop structure formed by the locking piece and the locking groove 41 not only can limit and lock the hand-held handle 12, but also can reserve some space to properly adjust the position of the hand-held handle 12.

In some embodiments, in order to limit the movement of the locking member 5, as shown in fig. 5 to 6, a limit rail 42 for limiting the movement range of the locking member is provided in the casing 4, and the limit rail 42 is disposed around the locking slot 41.

Since the locking slot 41 is a semicircular slot, the track path of the limit rail 42 surrounding the locking slot 41 is not necessarily larger than a semicircular arc, so that in order to avoid the slipping phenomenon of the arc plate 52 when moving on the limit rail 42, the arc plate 52 can be set to be larger than a semicircular plate body, and thus when the arc plate 52 and the locking slot 41 form a closed loop structure, one end of the arc plate 52 far away from the stop surface 51 can still be partially located on the limit rail 42.

Further, a guide block 54 capable of abutting against the side wall of the limit rail 42 is integrally provided on the inner side wall of the limit chute 53. The movement direction of the arc plate 52 on the limit rail 42 can be guided by the arrangement of the guide block 54 in cooperation with the limit chute 53.

To effect the driving of the movement of the arcuate plate 52, in some embodiments, the driving member comprises a first gear 6 and on the outer side wall of the arcuate plate 52 is provided with a toothed structure 55 capable of meshing with the first gear 6.

The first gear 6 can stop the transmission of the arcuate plate 52 by providing a smooth surface 56 to limit the movement limit of the arcuate plate 52.

Further, the first gear 6 may be driven manually or electrically. When manual, referring to fig. 5, a rotating handle 61 located outside the housing 4 may be connected at the axial center of the first gear 6. The first gear 6 can be conveniently forced by rotating the handle 61, so that the purpose of saving labor is achieved. When the electric mode is adopted, referring to fig. 7, a second gear 62 meshed with the first gear 6 is arranged in the casing 4, and a driving motor 63 coaxially connected with the second gear is arranged on the casing 4. In practical application, the manual or electric driving mode is flexibly selected according to the requirements of users.

In some embodiments, referring to fig. 4-5, the casing 4 includes an upper casing 43 and a lower casing 44 that are fixedly connected, and a first accommodating groove and a second accommodating groove that are mutually communicated are formed between the upper casing 43 and the lower casing 44, where the first accommodating groove is used for accommodating the driving member, and the second accommodating groove is used for accommodating the locking member. The driving piece and the locking piece can be initially limited through the arrangement of the first accommodating groove and the second accommodating groove. Further, the upper case 43 is provided with a through hole through which the rotating handle 61 is inserted, and the upper case 43 is provided with a locking direction indicator 431.

In some embodiments, the connecting member 3 may be of a fixed structure or a telescopic structure. In practice, the distance between the base 2 and the standing locking structure is usually fixed, while the design of the connecting element 3 as a telescopic structure is mainly based on transportation cost considerations. During transportation, the connecting piece 3 is stretched to the minimum size, so that the whole transportation space of the mechanism is saved to a certain extent, and the transportation cost is reduced.
