One way of achieving thesuction unit 30 is that thesuction unit 30 comprises a motor and a fan, the motor being adapted to drive the fan in rotation to generate a suction airflow. A filtering device may be further provided between the first air flow passage and thesuction unit 30 to prevent dust from entering into thesuction unit 30.
Further, in the present embodiment, in order to make the center of gravity of thesuction unit 30 closer to the hand-heldportion 201, the arrangement of thesuction unit 30 may be achieved in various ways. For example, thehandheld portion 201 has an extension line extending along the extending direction of thehandheld portion 201, and thesuction unit 30 may be disposed based on the position of the extension line of thehandheld portion 201, and the extension line of thehandheld portion 201 may be referred to as a dotted line a in fig. 2 and 3.
Referring to fig. 2, thesuction unit 30 is arranged in such a manner that thesuction unit 30 is located between an extension line of the hand-heldportion 201 and thedust collection assembly 10. In this arrangement, thesuction unit 30 is disposed above the hand-heldportion 201 on the side close to thedust collection assembly 10, and thesuction unit 30 may be disposed on the front side of the upper end of the hand-heldportion 201. The gravity center of thesuction unit 30 is relatively located at the middle position of the whole machine, and the part of the gravity center is close to thehandheld portion 201, so that the gravity center of the whole machine is close to thehandheld portion 201, the gravity of thesuction unit 30 can be better transmitted to thehandheld portion 201, and the holding hand feeling of a user is better. Further, the upper part of the extension line of thehandheld portion 201 and the position behind theaccommodating portion 202 can be used for arranging thesecond battery pack 402 of the battery assembly 40, so that the battery assembly 40 with a larger weight can also transmit the gravity to thehandheld portion 201 more directly, and the holding hand feeling of the user is improved.
Referring to fig. 3, another arrangement of thesuction unit 30 is that an extension line is positioned between thesuction unit 30 and thedust collection assembly 10. In this arrangement, thesuction unit 30 is disposed above thehandle 201 on the side away from thedust collection assembly 10, and thesuction unit 30 may be disposed on the rear side of the upper end of thehandle 201. The center of gravity of thesuction unit 30 is far away from the middle position of the whole machine and is arranged closer to thehandheld part 201, so that the gravity of thesuction unit 30 can be more directly transmitted to thehandheld part 201, and the holding hand feeling of a user is better. Further, the upper part of the extension line of thehandheld portion 201 and the position of theaccommodating portion 202 in front can be used for arranging thesecond battery pack 402 of the battery assembly 40, so that the battery assembly 40 with a larger weight can transmit the gravity to thehandheld portion 201 more directly, and the holding hand feeling of the user is improved.
Yet another arrangement of thesuction unit 30 is that the extension line passes through thesuction unit 30. In this arrangement, thesuction unit 30 is disposed above thehandheld portion 201, so that the gravity of thesuction unit 30 can be directly transmitted to thehandheld portion 201, and compared with thehandheld portion 201, thesuction unit 30 has less influence of the weight bias, and has better hand feeling. Further, the positions of both sides of thesuction unit 30 may be used to dispose thesecond battery pack 402 of the battery assembly 40.
With continued reference to fig. 2, the arrangement of thesuction unit 30 when thesuction unit 30 is positioned between the extension line and thedust collection assembly 10 also includes various arrangements. In one implementation, thesuction unit 30 is located in theaccommodating portion 202, that is, thesuction unit 30 is entirely disposed in theaccommodating portion 202, and the gravity of thesuction unit 30 can completely act on thehandheld portion 201, so as to facilitate the conduction of the gravity and the action on the hand of the user, so that the unbalanced condition is reduced, and the hand-holding feeling of the user is ensured. The dotted line B in fig. 2 is an edge boundary line of one side of thedust collection assembly 10, a part on the left side of the dotted line B is thedust collection assembly 10, a part on the right side of the dotted line B is thehandle assembly 20, and thesuction unit 30 is entirely disposed in theaccommodating part 202, i.e., it is illustrated that thesuction unit 30 is entirely located on the right side of the dotted line B.
Referring to fig. 2, another arrangement of thesuction unit 30 is that thesuction unit 30 is at least partially disposed in theaccommodating part 202 and partially disposed in thedust collection assembly 10. In this way, the dotted line B passes through thesuction unit 30, i.e., thesuction unit 30 is partially located at the right side of the dotted line B and partially located at the left side of the dotted line B. By the arrangement, the gravity center of thesuction unit 30 is relatively positioned at the middle position of the whole machine, and part of the gravity center is close to thehandheld part 201. In addition, thesuction unit 30 occupies less space in theaccommodating portion 202, and when thesecond battery pack 402 is disposed in theaccommodating portion 202, thesecond battery pack 402 can be closer to thehandheld portion 201, and the gravity of thesecond battery pack 402 is more directly transmitted to thehandheld portion 201, so as to ensure the holding feeling of the user.
Yet another arrangement of thesuction unit 30 is that thesuction unit 30 is located above thedust collection assembly 10, i.e., thesuction unit 30 is located entirely to the left of the dotted line B. In this way, only thesecond battery pack 402 can be accommodated in theaccommodating portion 202, the center of gravity of the battery assembly 40 can be biased to the rear position of the whole machine, and the center of gravity of thesuction unit 30 is relatively located at the front position of the whole machine and balanced with the center of gravity of the battery assembly 40, so that the center of gravity of the whole machine tends to the center position and can be close to thehandle assembly 20, and thus the gravity of the whole machine is transmitted to thehandheld portion 201 to ensure the holding hand feeling of the user.
Further, in the embodiment of the present application, thefirst battery pack 401 is disposed in thehandheld portion 201, and thesecond battery pack 402 is disposed in theaccommodating portion 202, so that the gravity of thefirst battery pack 401 directly acts on thehandheld portion 201, and thus, a user can directly provide acting force for thefirst battery pack 401, and the condition of heavy weight is reduced. Thesecond battery pack 402 can be matched with the position of thesuction unit 30 for setting, thesecond battery pack 402 can be arranged at the front side of the upper end of thehandheld portion 201 and also can be arranged at the rear side of the upper end of thehandheld portion 201, the gravity center of thesecond battery pack 402 is arranged close to thehandheld portion 201, so that the gravity of thesecond battery pack 402 can be directly conducted to thehandheld portion 201, the acting force is applied by a user conveniently, and the holding hand feeling of the user is better. In the embodiment of the present application, the arrangement between thesecond battery pack 402 and thesuction unit 30 includes various arrangements, and one way to achieve this is that, referring to fig. 2, thesuction unit 30 is located between thesecond battery pack 402 and thedust collection assembly 10. Referring to fig. 3, another arrangement between thesecond battery pack 402 and thesuction unit 30 is that thesecond battery pack 402 is located between thesuction unit 30 and thedust collection assembly 10. Thesuction unit 30 and thesecond battery pack 402 can well transmit the gravity to thehandheld portion 201, so that the weight bias of the whole machine is reduced, and the holding hand feeling of a user is ensured.
Further, to enable thesecond battery pack 402 to conduct gravity more directly onto thehandle portion 201, an extension line (i.e., a dotted line a) of thehandle portion 201 passes through thesecond battery pack 402. Thesecond battery pack 402 is arranged above thehandheld portion 201, so that gravity of thesecond battery pack 402 can be directly conducted to thehandheld portion 201, and compared with thehandheld portion 201, the second battery pack is small in weight influence and good in holding hand feeling.
To further ensure the working performance of the battery assembly 40, it is necessary to cool the battery assembly 40 so that the battery assembly 40 can work at an appropriate temperature to ensure the working efficiency. In some embodiments, one way to cool the battery assembly 40 is to provide thehandheld portion 201 with a second air flow channel, theair inlet 2031 of the second air flow channel is disposed at an end of thehandheld portion 201 away from theaccommodating portion 202, and the air outlet of the second air flow channel is communicated with the air inlet of thesuction unit 30. The battery assembly 40 is located in the second airflow path. One arrangement of theintake ports 2031 can be seen in FIG. 1.
When thesuction unit 30 is operated, a suction air flow is generated, the source of which is divided into two parts, one part originating from theair inlet passage 103 on thedust collection assembly 10, which suction air flow is used for sucking the external dust-laden air for cleaning operation, and the air flow enters thesuction unit 30 through the first air flow passage. Another part of the suction airflow is from theair inlet 2031 at an end of thehandle 201 away from theaccommodating portion 202, as shown by the solid arrows in fig. 2 and 3, and enters thesuction unit 30 through the second airflow channel, and since the temperature of the sucked air is low, the airflow takes away heat from the battery assembly 40 when flowing through the second airflow channel, thereby cooling the battery assembly 40. To prevent dust from flowing from theair inlet 2031 into the second air flow path, a filter structure, such as a filter net, filter cotton, etc., is disposed at theair inlet 2031 to block dust.
In order to better communicate the air outlet of the second air flow channel with the air inlet of thesuction unit 30, referring to fig. 4, in the embodiment of the present application, apartition 2021 is disposed in theaccommodating portion 202, and thepartition 2021 divides the interior of thehandle assembly 20 into a motor cavity and a battery cavity. Thesuction unit 30 is arranged in the motor cavity, the motor cavity is communicated with the first air flow channel, and an air outlet is formed in the cavity wall of the motor cavity. The suction air from theair inlet channel 103 enters the motor cavity through the first air channel and is then discharged from the air outlet.
The battery assembly 40 is disposed in the battery cavity, the battery cavity is a second air flow channel, and the battery cavity is communicated with the air inlet of thesuction unit 30 through a thirdair flow channel 2022. Thethird airflow channel 2022 includes, but is not limited to, a duct structure, and the suction airflow from theair inlet 2031 flows through the second airflow channel, i.e., the battery cavity, to take away heat from the battery assembly 40, and after the battery assembly 40 is cooled, the airflow flows into the motor cavity through thethird airflow channel 2022, and is then exhausted from the air outlet. Further, to better cool the battery assembly 40, the portion of theaccommodating portion 202 including the battery cavity may also be provided with anair inlet 2031.
Another way of achieving communication between the air outlet of the second air flow channel and the air inlet of thesuction unit 30 is that, referring to fig. 3, thesuction unit 30 is located downstream of the battery assembly 40, and the air inlet of thesuction unit 30 is directed towards the battery assembly 40. In this way, the air inlet of thesuction unit 30 faces the battery assembly 40, when thesuction unit 30 works, the air flow in the second air flow channel can be directly sucked, when the air flow flows between the second air flow channel and thesuction unit 30, the obstruction is less, the mobility is better, and the cooling efficiency is effectively improved.
With continued reference to fig. 1-4, in some embodiments of the present disclosure, to make the cleaning device more stable when not in use, the end of thehandle 201 away from thereceptacle 202 is provided with abase 203. The size of the end part of thehandheld part 201 can be increased through thebase 203, so that the contact area of thehandheld part 201 and a placing surface is increased, and more effective support is provided for the whole machine. In order to make the support of the base 203 more stable, thebase 203 is connected to thedust collecting assembly 10, thehandle 201 and thedust collecting assembly 10 form a relatively stable structure through thebase 203, and thedust collecting assembly 10 shares a part of the stress of thebase 203, so that the base 203 can be supported better.
Theinlet 2031 of the second air flow channel is disposed on thebase 203. Thebase 203 is located relatively far away from the battery assembly 40, and when the air flow enters the second air flow channel through theair inlet 2031 on thebase 203, the air flow can completely pass through the battery assembly 40, so that the occurrence of a cooling blind spot is reduced, and the cooling efficiency of the battery assembly 40 is improved.
Based on the handheld cleaning device provided in the above embodiment, the present embodiment also provides another handheld cleaning device, which is different from the above embodiment in the arrangement manner of thesuction unit 30.
In one implementation, referring to fig. 1 and 2, a hand-held cleaning device includes: adust collection assembly 10, ahandle assembly 20, asuction unit 30, and a battery assembly 40.
Wherein thedust collection assembly 10 has a first air flow passage. Thehandle assembly 20 includes ahandle portion 201 and a receivingportion 202 disposed at an upper end of thehandle portion 201, and the receivingportion 202 is connected to thedust collecting assembly 10 and is communicated with the first air flow passage. Thesuction unit 30 serves to generate a suction airflow, which passes through the first airflow passage.
