DETAILED DESCRIPTION

[0041] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0042] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms "a", "the", and "said" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. "Plurality" generally includes at least two, and other quantifiers are similar.

[0043] It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present disclosure for description, these descriptions should not be limited to these terms. These terms are only used to distinguish the objects to be described. For example, without departing from the scope of the embodiments of the present disclosure, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. In addition, the terms "first", "second", "third", etc. are only for descriptive purposes and should not be construed as indicating or implying relative importance.

[0044] It should be understood that the term "and / or" used herein is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after. The singular forms "a", "the", and "said" are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0045] In the description of the present disclosure, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0046] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a commodity or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such commodity or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the commodity or device comprising said element.

[0047] In the related art, in order to enhance the cleaning effect, a dust collection device often increases the suction power of the power source and then discharges the air flow outside the dust collection device. On the one hand, since the power of the power source increases, the rotational speed of the power source speeds up, and the noise generated by the power source blades themselves also increases. On the other hand, increasing the power results in an increase in the flow velocity of the air flow. Since there is no noise reduction measure or the noise reduction measure is imperfect during the discharge process of the air flow, the friction between the air flow and the components in the flow channel during the discharge process increases the air flow noise, bringing an unpleasant experience to the user.

[0048] Therefore, the embodiments of the present disclosure provide a power source assembly, including: a power source body assembly, including an air inlet and an air outlet; a duct assembly communicating with the power source body assembly, the duct assembly including: a duct housing configured to provide an air flow output path; a baffle assembly disposed on the air flow output path and configured to make the output air flow output in a zigzag manner to reduce the air flow noise.

[0049] In the power source assembly provided by the present disclosure, by providing a baffle assembly on the air flow output path of the duct assembly, when the air flow flows out from the air outlet and towards the outside of the power source assembly, a tortuous flow path is formed. Compared with an unobstructed flow path, the tortuous flow path can reduce the air flow velocity, thereby reducing the noise generated by the air flow passing through the duct assembly.

[0050] The optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0051] As Figure 1 shown, in order to more clearly describe the positional relationship of each structure in the power source assembly 100, the following direction definitions are made in the present disclosure: the X-axis direction is defined as the third direction, the arrow direction along the X-axis is marked as "positive third direction", and the direction opposite to the arrow direction along the X-axis is marked as "negative third direction"; the Y-axis direction is defined as the first direction, the arrow direction along the Y-axis is marked as "positive first direction", and the direction opposite to the arrow direction along the Y-axis is marked as "negative first direction"; the Z-axis direction is defined as the second direction, the arrow direction along the Z-axis is marked as "positive second direction", and the direction opposite to the arrow direction along the Z-axis is marked as "negative second direction".

[0052] As Figure 1 - Figure 2As shown, an embodiment of the present disclosure provides a power source assembly 100, which is applied to a dust collection device to provide suction power. The power source assembly 100 generally includes components such as a fan assembly and an air pump assembly that can provide suction power. In this embodiment, the fan assembly is taken as an example for illustration.

[0053] The power source assembly 100 includes a power source body assembly 110. The power source body assembly 110 includes a power source body 113, an air inlet 111, and an air outlet 112. The power source body 113 is a device that provides suction power, such as a fan. The power source body 113 is controlled to rotate by a control signal, so that air flow enters the power source body assembly 110 from the air inlet 111 and then flows out from the air outlet 112. The power source assembly 100 further includes a duct assembly 120. The duct assembly 120 is in communication with the power source body assembly 110. The air flow enters the duct assembly 120 through the air outlet 112 and is discharged from the power source assembly 100 after passing through the duct assembly 120. The duct assembly 120 includes a duct housing 130 configured to provide an air flow output path. The duct housing 130 is generally in a cuboid or cylindrical structure. In this disclosure, the cuboid structure is taken as an example for illustration. The duct assembly 120 includes a baffle assembly 140. The baffle assembly 140 is disposed on the air flow output path. After the air flow enters the duct assembly 120 from the air outlet 112, it flows in a zigzag manner under the action of the baffle assembly 140 and then is discharged from the duct assembly 120. Since the baffle assembly 140 makes the air flow output path extend in a zigzag manner, the air flow noise can be reduced. Optionally, multiple baffle assemblies 140 can be arranged in a staggered manner, so that the air flow entering from the power source body assembly 110 cannot directly flow from one end of the duct assembly 120 to the other end, but forms a circuitous path after being blocked by the baffle assembly 140, thereby reducing the air flow speed and reducing the noise at the same time.

[0054] As Figure 3 、 Figure 4 shown, the cuboid duct housing 130 includes a first side wall 131, a second side wall 132, a third side wall 133, a fourth side wall 134, and a fifth side wall 135. Among them, the first side wall 131 and the second side wall 132 are oppositely arranged, the third side wall 133 and the fourth side wall 134 are oppositely arranged, and the fifth side wall 135 is disposed at one end away from the air outlet 112. In some embodiments, the duct housing 130 includes a plurality of air outlet holes 150. The air outlet holes 150 are disposed on a side of the duct housing 130 away from the power source body 113, for example, on at least one of the first side wall 131, the second side wall 132, the third side wall 133, the fourth side wall 134, and the fifth side wall 135.

[0055] In some embodiments, as Figure 4As shown, the baffle assembly 140 includes at least one first baffle 141. The first baffle 141 extends from the first side wall 131 to the second side wall 132 of the air duct housing 130 and has a first gap with the second side wall 132. Multiple first baffles 141 can prevent at least part of the air flow from directly flowing in the third direction, thus forming a tortuous path; In some embodiments, the baffle assembly 140 includes at least one second baffle 142. The second baffle 142 extends from the second side wall 132 to the first side wall 131 of the air duct housing 130 and has a second gap with the first side wall 131. Multiple second baffles 142 can prevent at least part of the air flow from directly flowing in the third direction, thus forming a tortuous path; In some embodiments, the first side wall 131 and the second side wall 132 are oppositely arranged; In some embodiments, the first baffle 141 and the second baffle 142 overlap in the third direction, so that the air flow cannot directly flow in the third direction. By staggering at least one first baffle 141 and at least one second baffle 142, after the air flow flows out of the air outlet 112, it is blocked by the second baffle 142 and changes direction, and then continues to flow outwards along the first gap, and then is blocked by the first baffle 141 and changes direction again to flow outwards from the second gap, and so on, so that the air flow flows outwards in a tortuous manner, which can reduce the air flow velocity, thereby reducing the noise generated by the air flow passing through the air duct assembly. Therefore, in the embodiments of the present disclosure, by providing at least one first baffle 141 and at least one second baffle 142, the length of the exhaust air duct is increased, the wind speed is reduced, and thus the wind noise is reduced. The design of at least one first baffle 141 and at least one second baffle 142 can increase the reflection and refraction of sound waves, hinder the direct outward propagation of noise, increase the sound propagation loss, and achieve the noise reduction effect.

[0056] In some embodiments, as Figure 4 As shown, the air duct assembly 120 further includes a sound absorption structure 160. The sound absorption structure 160 is at least partially filled between the baffle assemblies 140. It can be understood that the sound absorption structure 160 fills part or all of the space formed between multiple baffle assemblies 140. The sound absorption structure 160 can be flexibly arranged according to the final air performance and noise performance of the product, so that at least a part of the path of the air flow from the air outlet 112 to the air outlet hole 150 passes through the sound absorption structure 160, and the air flow velocity is further reduced, thereby further reducing the noise. Optionally, the sound absorption structure 160 can be any sound-absorbing material such as sound-absorbing cotton, sound-absorbing cloth, sound-absorbing organic material, etc., and no limitation is made thereto.

[0057] In some embodiments, as Figure 4As shown, the power source body assembly 120 includes a power source housing 114, and the power source housing 114 is connected to the air duct housing 130; a power source body 113 is disposed within the power source housing 114; wherein, rotation of the power source body 113 causes air flow to enter the power source body 113 in a second direction, and the air flow enters the air duct assembly 120 from the power source housing 114 in a third direction. The outer shape of the power source housing 114 generally matches the outer contour of the power source body 113. For example, the power source housing 114 generally has a cylindrical outer shape, and its side wall is joined to the air duct housing 130 to form a detachable or integral structure.

[0058] In some embodiments, the width of the air duct housing 130 in a first direction is less than the width of the power source housing 114 in the first direction; and / or, the width of the air duct housing 130 in a second direction is less than the width of the power source housing 114 in the second direction. Optionally, the width of the air duct housing 130 in the first direction is 0.5 - 0.95 times the width of the power source housing 114 in the first direction; and / or, the width of the air duct housing 130 in the second direction is 0.5 - 0.95 times the width of the power source housing 114 in the second direction. By setting the width of the air duct housing 130 in the first and second directions to be as wide as possible, the flow rate of the air flow within the air duct housing 130 is further reduced, and the noise of the power source assembly is reduced. To take into account the overall positional relationship of the power source assembly within the dust collection device, the width of the air duct housing 130 in the first direction can be set to be 0.5 - 0.95 times the width of the power source housing 114 in the first direction; the width of the air duct housing 130 in the second direction is 0.5 - 0.95 times the width of the power source housing 114 in the second direction.

[0059] In some embodiments, as Figure 4 、 Figure 5 shown, the power source body assembly 110 further includes a first soft rubber pad 115, and the first soft rubber pad 115 is disposed between the power source housing 114 and the power source body 113, and is located at one end of the air inlet 111 of the power source housing 114. The first soft rubber pad 115 is used to connect the power source body 113 and the power source housing 114. The first soft rubber pad 115 can be made of a soft rubber material such as silica gel or rubber. The first soft rubber pad 115 can achieve a good vibration isolation effect. At the same time, the first soft rubber pad 115 is designed with structural features that match the structures of the power source body 113 and the power source housing 114, and can closely fit the power source body 113 and the power source housing 114 for fixing the power source body 113. Optionally, the first soft rubber pad 115 is designed with a structure having multiple cutouts to reduce the stiffness of the soft rubber, further increase the vibration isolation effect, reduce the transmission of vibration during the operation of the fan to other housings, and thereby reduce the noise generated by the vibration of the housing.

[0060] In some embodiments, the power source body assembly 110 further includes a second soft rubber pad 116. The second soft rubber pad 116 is disposed between the power source housing 114 and the power source body 113, and is located at an end of the power source housing 114 away from the air inlet 111. The second soft rubber pad 116 is used to connect the power source body 113 and the cover plate of the power source body 113 bin. The first soft rubber pad 115 and the second soft rubber pad 116 can be made of soft rubber materials such as silica gel or rubber. The second soft rubber pad 116 can achieve a good vibration isolation effect. At the same time, the second soft rubber pad 116 is designed with structural features that match the structures of the power source body 113, the power source housing 114, and the fan bin cover plate, and is used to fix the power source body 113. Optionally, the second soft rubber pad 116 is designed with a structure with multiple hollowed-out parts, which is used to reduce the stiffness of the soft rubber, further increase the vibration isolation effect, reduce the transmission of the vibration generated during the operation of the fan to other housings, and thus reduce the noise generated by the vibration of the housing.

[0061] As Figure 6 shown, the embodiment of the present disclosure further provides a dust collection device 200, including the power source assembly 100 described in any one of the above. The power source assembly 100 is reasonably arranged according to the positional relationship of other components of the dust collection device 200. In the embodiment of the present disclosure, the power source assembly 100 is disposed substantially vertically in the dust collection device 200. Among them, for other structures and functions in the dust collection device 200, reference may be made to related dust collection devices, and details thereof will not be elaborated herein.

[0062] Finally, it should be noted that the embodiments in this specification are described in a progressive manner, and the key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments may be referred to each other. For the system or device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and reference may be made to the description of the method part for related parts.
