According to one embodiment of the present application, the bottom surfaces of the separator body 110 and the handle body 150 together support the hand-held cleaner. Referring to fig. 1, in the present embodiment, a handle main body 150 is disposed at one side of the separator main body 110, the handle main body 150 includes a top housing 151, a bottom housing 153, and a handle 152, and the handle 152 is disposed between the top housing 151 and the bottom housing 153.

Meanwhile, the separator body 110 is further provided with an air inlet 111 and an air outlet 112 through which a suction airflow flows. As shown in fig. 4, an accommodating space is further formed at a side of the separator body 110 close to the handle body 150 for accommodating a battery assembly 160.

Referring to fig. 2, a dust collecting portion 113 is disposed in the separator body 110, a dust collecting space 1131 is disposed in the dust collecting portion 113, and the air inlet 111 and the air outlet 112 are both disposed on the separator body 110 and are respectively communicated to the dust collecting space 1131. In this embodiment, the dust collecting space 1131 is located near the lower side of the separator body 110, and the bottom of the dust collecting part 113 is provided with an openable dust collecting cover 1132. Within the dust collecting space 1131, a dust-air separation assembly 140 is provided for effecting separation of dust from the suction airstream. Here, the dust-gas separating assembly 140 is a cyclone multi-cone separating mechanism. It is understood that, in other embodiments, the dust collecting space 1131 may be disposed at other positions of the separator main body 110, and the dust-gas separating assembly 140 may also be a centrifugal separating mechanism that separates dust gas by using centrifugal force, which is not limited in this embodiment.

With continued reference to fig. 2, a receiving chamber 1511 is formed in the top housing 151, and the receiving chamber 1511 is used for accommodating various components such as the motor assembly 130. Here, the top case 151 and the separator body 110 are arranged at a right angle, a handle 152 is coupled to a lower side of the top case 151 so as to be held by a user, and a bottom case 153 is coupled to a lower side of the handle 152, and the bottom case 153 and the separator body 110 are also arranged at a right angle. An openable chamber cover 1512 is disposed at an end of the accommodating chamber 1511 away from the dust collecting part 113 for assembly, disassembly, and cleaning.

The filter assembly 120 is used to further filter the suction airstream passing through the dust and gas separation assembly 140 or to directly filter the suction airstream without the dust and gas separation assembly 140. In the present embodiment, referring to fig. 2 and 4, the filter assembly 120 includes a carrier 121 and a first filter element 122. Wherein the carrier 121 may be integrally formed with the separator body 110 or may be disposed within the separator body 110. The first filter element 122 comprises filter cotton 1221 and a hypa filter element 1222, and the filter cotton 1221 is arranged inside the hypa filter element 1222. Here, referring to fig. 4 and 6, the carrier 121 includes a main body 1211 disposed at a top position of the dust collecting space 1131 and having a lower end connected to the dust collecting space 1131, and at least a portion of the first air passage 116 is formed at the carrier 121. Here, the first air duct 116 is used to communicate the dust collecting space 1131 with the motor assembly 130, and specifically, the first air duct 116 communicates with the dust collecting space 1131 at the upstream and communicates with the motor assembly 130 at the downstream. The first filter element 122 is located in the first air duct 116, and after the suction airflow enters the filter assembly 120, the suction airflow is sequentially filtered by the filter cotton 1221 and the hepa filter element 1222, so as to achieve a better filtering effect. At the same time, the flow rate of the suction air flow will be reduced as it passes through the filter cotton 1221 and the HEPA filter 1222 in sequence, thereby achieving two-stage noise reduction of the suction air flow. It is understood that, in other embodiments, the first filter element 122 is not limited to the above structure, and may be only the filter cotton 1221, or only the hypa filter element 1222, or other filter elements, etc., which are not limited in this embodiment, and the filter assembly 120 may also be disposed in the dust collecting space 1131, or partially disposed in the dust collecting space 1131.

Meanwhile, a second air passage 117 is formed between the main body 1211 and the inner wall of the handle main body 150, where the second air passage 117 is used for communicating the motor assembly 130 and the air outlet 112, and specifically, the second air passage 117 is communicated to the motor assembly 130 at the upstream and to the air outlet 112 at the downstream. Here, the outlet 112 is provided in a ring shape, which is embodied as a spaced-apart opening arranged along a ring shape. It is understood that, in other embodiments, the air outlet 112 may also be a continuous opening, and this embodiment does not limit it to several spaced openings.

It is understood that in one embodiment, at least a portion of the first air duct 116 and the second air duct 117 may be defined at the filter assembly 120, and in other embodiments, the implementation is not limited thereto. For example, a first air channel 116 is provided between the dust collecting space 1131 and the motor assembly 130, and a second air channel 117 is provided between the air outlet 112 and the motor assembly 130.

In the present embodiment, with continued reference to fig. 4 and 6, the motor assembly 130 is disposed on the top housing 151 of the handle main body 150. Also, the motor assembly 130 is located in the receiving chamber 1511 of the top housing 151 on a side thereof remote from the first filter element 122. Referring to fig. 4 and 6, the carrier 121 has an extension 1212 extending into the receiving cavity 1511, or the extension 1212 may be provided separately from the carrier 121, for example, the extension 1212 is a separate component from the carrier 121 and is connected to the receiving cavity 1511, or the extension 1212 and the top housing 151 are integrally formed, etc. Here, a portion of the first air passage 116 is located in the separator main body 110, which is an engaging air passage 1161 defined by the main body 1211. Another portion of the first air duct 116 is located in the top housing 151 of the handle main body 150, the portion of the first air duct 116 is a first sub-air duct 1162, and in this embodiment, the first sub-air duct 1162 is defined by the extension portion 1212. The motor assembly 130 is connected to the first sub-air duct 1162 at the extending portion 1212 at the upstream side, and the first air duct 116 extends toward the motor assembly 130 through the extending portion 1212, so that the motor assembly 130 farther from the first filter element 122 is communicated with the first air duct 116. Here, the motor assembly 130 is located relatively far from the first filter element 122, and the suction air flow needs to travel a longer distance to reach the motor assembly 130 after passing through the first filter element 122, so that the stroke of the suction air flow is increased, which helps to reduce the noise thereof.

Meanwhile, referring to fig. 2, the air outlet 112 is disposed at a top position of the separator body 110, and the air outlet 112 faces an upper side or a circumferential outer side of the separator body 110, so as to prevent an air outlet direction of the suction airflow from directly facing a user. Here, the second air channel 117 includes a portion located in the accommodating chamber 1511 of the top housing 151 and a portion located in the handle main body 150, wherein the portion located in the accommodating chamber 1511 is a second sub-air channel 1171, and the portion located in the handle main body 150 is an outlet air channel 1172. Illustratively, the portion of the airflow passage located in the top housing 151 is divided into a first sub-duct 1162 and a second sub-duct 1171 by the extension portion 1212. Referring to fig. 4 and 6, in the present embodiment, the portion of the airflow channel located in the top housing 151 may be divided into a first sub-air channel 1162 located inside the extending portion 1212 and a second sub-air channel 1171 located on the upper side of the extending portion 1212. The extension portion 1212 and the motor assembly 130 jointly divide the second sub-air channel 1171, that is, the second air channel 117 is formed between the motor assembly 130 and the inner wall of the receiving cavity 1511, and between the extension portion 1212 of the carrier 121 and the inner wall of the receiving cavity 1511. Specifically, in fig. 4, the flow direction of the suction air flow in the first sub-air passage 1162 is from left to right, and the flow direction of the suction air flow in the second sub-air passage 1171 is from right to left, that is, the movement direction of the suction air flow at the motor needs to be changed by 180 degrees, so that the flow speed of the suction air flow can be reduced, and in other embodiments, the two air passages may also be arranged at an acute angle. The second sub-duct 1171 and the air outlet direction of the air outlet 112 (in this embodiment, the setting direction of the outlet duct 1172) form an angle, specifically 90 ° in this embodiment, so that the movement direction of the sucked air flow needs to be changed when the sucked air flow enters the outlet duct 1172 from the second sub-duct 1171, and the flow speed of the sucked air flow can be reduced. Further, the cross-sectional area of the first sub-stacks 1162 is set to be greater than the cross-sectional area of the second sub-stacks 1171, illustratively, the ratio of the cross-sectional area of the first sub-stacks 1162 to the cross-sectional area of the second sub-stacks 1171 is equal to or less than 2:1, the relative arrangement of the first sub-duct 1162 and the second sub-duct 1171 achieves better noise reduction effect. According to another embodiment of the present application, the ratio of the cross-sectional area of the first sub-plenum 1162 to the cross-sectional area of the second sub-plenum 1171 is between 3:2 and 2: 1. It is understood that, in other embodiments, the second sub-air channel 1171 is not limited to the above structure, for example, the second sub-air channel 1171 may be formed by an inner wall of the motor assembly 130, and the like, which is not limited by this embodiment.

Here, the motor assembly 130 communicates with the dust collecting space 1131 through the first air duct 116, and communicates with the air outlet 112 through the second air duct 117. In use, the suction airflow generated by the motor assembly 130 firstly enters the dust collecting space 1131 through the air inlet 111, then passes through the first air duct 116 at the filter assembly 120 to reach the motor assembly 130, and then passes through the second air duct 117 at the filter assembly 120 to reach the air outlet 112. I.e. the suction air flow reaches the position of the filter assembly 120 before leaving and then returns again to the position of the filter assembly 120 and finally leaves the separator body 110, in which process the travel path of the suction air flow is extended, the flow rate is reduced and finally the suction air flow is less noisy when leaving the separator body 110.

Moreover, in the handheld vacuum cleaner provided by the embodiment, the first air duct 116 and the second air duct 117 are defined at the position of the filtering assembly 120 that the existing handheld vacuum cleaner generally has, and the air duct structure is not excessively artificially added at the handle 152 or other parts, so that the main structure of the existing handheld vacuum cleaner does not need to be changed basically, the spatial layout of the existing separator main body 110 is utilized to achieve the effect of reducing noise, and the structural modification and production cost is reduced.

Meanwhile, the carrier 121 extends into the receiving space 1511 of the top case 151, and the motor assembly 130 is disposed near a side of the top case 151 remote from the dust collecting part 113 and communicates with the first air passage 116 defined by the carrier 121, i.e., the relative distance between the motor assembly 130 and the separator body 110 is made longer, so that the stroke required for the suction air to pass is made longer, so that the flow rate of the suction air is reduced and thus noise is reduced. It is understood that in other embodiments, the motor assembly 130 may be disposed at a side close to the separator body 110, and the carrier 121 may not extend into the top housing 151, which is not limited in this embodiment, but the noise reduction effect is reduced accordingly.

In some embodiments, referring to fig. 3, the dust collecting space 1131 has a longitudinal direction X; the first filter element 122 extends along the longitudinal direction, i.e., is disposed at a zero angle with respect to the longitudinal direction. Here, the first filter element 122 is substantially parallel to the longitudinal direction, and compared to a filter element structure disposed perpendicular to the longitudinal direction, the filter surface area of the air inlet surface and the air outlet surface of the first filter element 122 can be correspondingly increased, which is beneficial to enhancing the filtering effect, and the service life can also be increased due to the increase of the filter surface area. Meanwhile, the larger filtering area can also reduce the flow velocity of the suction airflow to a certain extent, so that the noise of the suction airflow is reduced. It is understood that, in other embodiments, due to space requirements, the first filter element 122 may not be disposed in parallel with the longitudinal direction, for example, the first filter element 122 may be disposed at an acute angle with respect to the longitudinal direction.

In some embodiments, referring to fig. 4 and 6, the filter assembly 120 further includes a second filter element 123, the second filter element 123 is connected to the carrier 121 and located upstream of the air outlet 113 to implement filtering, where the second filter element 123 is located outside the first filter element 122. Further the second filter element 123 is disposed perpendicular to the longitudinal direction, that is, the air inlet surface and the air outlet surface of the second filter element 123 are perpendicular to the longitudinal direction. Here, the second filter element 123 may better achieve filtration of the suction air flow, while the second filter element 123 contributes to further reduce the flow rate of the suction air flow and achieve a noise reduction effect. It is understood that in other embodiments, the second filter element 123 may be replaced with a sound-deadening member such as sound-deadening cotton for further noise reduction.

In some embodiments, referring to fig. 4, the dust-air separating assembly 140 and the first filter element 122 are detachably disposed on both sides of the carrier frame 121 along the longitudinal direction X of the dust collecting space 1131. Here, the first filter element 122 is located at the upper side of the bearing frame 121, and referring to fig. 2 again, the top of the separator body 110 is provided with an opening 115 for mounting and dismounting the first filter element 122. The first filter element 122 includes a top cover 1223, which is illustratively a part of the hepa filter element 1222, or it may be a structure for connecting the hepa filter element 1222 and/or the filter cotton 1221. Meanwhile, a ventilation opening 1224 is provided on the top cover 1223 at a position corresponding to the air outlet 112. When the first filter element 122 is mounted on the carrier frame 121, the top cover 1223 covers the opening 115 at the top of the separator body 110, the ventilation opening 1224 communicates with the ventilation opening 112, and a guide vane 1121 is further disposed at the ventilation opening 112 to guide the suction airflow to the ventilation opening 1224. Here, referring to fig. 3 and 5, the vent opening 1224 is located at a top position of the separator body 110. Referring to fig. 2 again, the dust collecting space 1131 is formed on the lower side of the carrier 121, and the dust-air separating assembly 140 is detachably mounted on the lower side of the carrier 121 and located in the dust collecting space 1131. Therefore, during assembly and disassembly, the first filter element 122 can be assembled and disassembled from the upper side of the separator body 110, the dust-air separation assembly 140 can be assembled and disassembled from the lower side of the separator body 110, and both can be separated from the separator body 110, so that the cleaning by a user is facilitated, and the user experience can be improved. In addition, the two are different in moving direction relative to the separator body 110 when they are mounted and dismounted, and they are not easy to interfere with each other.
