Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] The power component and the vacuum cleaner provided by this utility model will be described in detail below with reference to the embodiments.

[0026] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 , Figure 1 This is a first partial schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 2 This is a partial cross-sectional schematic diagram of an embodiment of the vacuum cleaner of this application; Figure 3 yes Figure 2 The structural diagram of A shown below; Figure 4This is a second partial schematic diagram of an embodiment of the vacuum cleaner of this application. This application provides a power assembly for a vacuum cleaner. The power assembly 14 is used to provide suction power. The power assembly 14 includes a power housing 141 and a power drive member 142. The power housing 141 forms a power cavity 1413. The power cavity 1413 forms an air inlet 14111 and an air outlet 14121 that communicate with each other. The power cavity 1413 provides mounting space and mounting position for the power drive member 142. The air inlet 14111 and the air outlet 14121 are interconnected. The air inlet 14111 is the air intake position of the power assembly 14. The air inlet 14111 is used to communicate with a dust cup assembly. The dust cup assembly is used to separate airflow carrying debris, wherein the debris is stored in the dust cup assembly, and the airflow enters the power assembly 14 through the air inlet 14111. The air outlet 14121 is the air outlet position of the power assembly 14, used for air outlet. The power drive component 142 is disposed within the power chamber 1413. The power drive component 142 is detachably connected to the power chamber 1413. The power drive component 142 generates a certain suction force to produce airflow from the air inlet 14111 to the air outlet 14121. The power drive component 142 may be, but is not limited to, a suction fan (not shown in the figure), etc.

[0027] The aforementioned power assembly 14 also includes a noise reduction cover 144 and a filter element 146. The noise reduction cover 144 is disposed on the upper end of the power cover 141. The noise reduction cover 144 is detachably or fixedly connected to the upper end of the power cover 141. In this embodiment, the noise reduction cover 144 is connected to the upper end of the power cover 141 by bolts or other means. When the noise reduction cover 144 is disposed on the upper end of the power cover 141, a noise reduction space 1451 is formed between the noise reduction cover 144 and the upper end of the power cover 141. This noise reduction space 1451 can perform a noise reduction function, reducing the noise of the power assembly 14 and thus improving the user experience.

[0028] A filter element 146 is disposed on the upper end of the noise reduction cover 144. The filter element 146 can be connected to the upper end of the noise reduction cover 144 by means of, but not limited to, snap-fit ​​or plug-in connections. The filter element 146 performs a filtering function. A power drive unit 142 is disposed within the power chamber 1413 and is used to generate airflow from the filter element 146, the noise reduction cover 144, the air inlet 14111, and the air outlet 14121. Under the suction force of the power drive unit 142, as the airflow filtered by the dust cup assembly exits from the bottom of the dust cup assembly and enters the power assembly 14, the filter element 146 further filters fine particles in the airflow. The airflow then exits along the noise reduction cover 144, the air inlet 14111, the power chamber 1413, and the air outlet 14121, thereby improving filtration efficiency. In addition, since the filter element 146 is located inside the noise reduction cover 144, the noise reduction cover 144 can block some fine dust and other particles from directly entering the power cover 141, thereby reducing the risk of damage to the power drive component 142 and thus improving the service life of the power drive component 142.

[0029] Therefore, through the combined action of the aforementioned power housing 141, power drive component 142, noise reduction housing 144, and filter component 146, not only is a noise reduction space 1451 formed between the noise reduction housing 144 and the upper part of the power housing 141, which can reduce the noise of the power component 14 and thus improve the user experience; but also, the filter component 146, located at the upper part of the noise reduction housing 144, can further filter fine particles in the airflow, thereby improving filtration efficiency; at the same time, the noise reduction housing 144 can prevent some fine dust from directly entering the power housing 141, which can reduce the risk of damage to the power drive component 142 and thus extend the service life of the power drive component 142.

[0030] In some embodiments, a noise-reducing connecting portion 1443 protrudes from the lower end of the noise-reducing cover 144. That is, the height of the noise-reducing connecting portion 1443 is higher than the height of the lower surface of the noise-reducing cover 144. The noise-reducing connecting portion 1443 is detachably or fixedly connected to the noise-reducing cover 144. In this embodiment, the noise-reducing connecting portion 1443 is integrally formed into the noise-reducing cover 1444. The noise-reducing connecting portion 1443 serves a connecting function, communicating with the air inlet 14111, allowing airflow to move along the noise-reducing connecting portion 1443 to the air inlet 14111. When the noise-reducing connecting portion 1443 protrudes from the lower surface of the noise-reducing cover 144, it also provides some support, supporting at least a portion of the filter element 146, etc. When the filter element 146 is at least partially supported by the noise reduction connecting part 1443, since the height of the noise reduction connecting part 1443 is higher than the height of the lower surface of the noise reduction cover 144, an air intake space 1452 is formed between the filter element 146 and the lower surface of the noise reduction cover 144. This air intake space 1452 can increase the air intake volume, thereby reducing the risk of airflow blockage.

[0031] In some embodiments, along the direction from the upper end to the lower end of the noise-reducing cover 144, the cross-sectional area of ​​the lower end of the noise-reducing cover 144 gradually decreases in the direction perpendicular to the upper end to the lower end of the noise-reducing cover 144. The lower end of the noise-reducing cover 144 is inclined downwards in the direction from the upper end to the lower end of the noise-reducing cover 144. Because the noise-reducing space 1451 is formed between the lower end of the noise-reducing cover 144 and the upper end of the power cover 141, the cross-sectional area of ​​the noise-reducing space 1451 gradually increases in the direction perpendicular to the upper end to the lower end of the noise-reducing cover 144.

[0032] By gradually reducing the cross-sectional area of ​​the lower end of the noise reduction cover 144, not only can a noise reduction space 1451 be formed, but the noise of the power component 14 can also be reduced, thereby improving the user experience; it can also form an air intake space 1452, increasing airflow. In addition, by limiting the change in the cross-sectional area of ​​the lower end of the noise reduction cover 144, while simultaneously forming the aforementioned noise reduction space 1451 and air intake space 1452, the structure is more compact and occupies less space.

[0033] Please continue reading Figures 1 to 4 In some embodiments, a support member 1441 is provided on the lower surface of the noise-reducing cover 144. The support member 1441 is detachably or fixedly connected to the bottom surface of the noise-reducing cover 144. In this embodiment, the support member 1441 is integrally formed on the bottom surface of the noise-reducing cover 144. The support member 1441 provides support and can be positioned at any location on the lower end of the noise-reducing cover 144, as long as it can support the filter element 146. By providing the support member 1441 at the lower end of the noise-reducing cover 144, the stability of the filter element 146 can be improved. The number of support members 1441 can be, but is not limited to, one, two, or more than three. The shape of the support member 1441 can be, but is not limited to, straight, curved, or arc-shaped.

[0034] In some embodiments, at least two support members 1441 are radially disposed on the lower surface of the noise reduction cover 144. The number of support members 1441 may be, but is not limited to, two, three, or more than four. Adjacent support members 1441 are spaced apart. By limiting the radial arrangement of at least two support members 1441, the stability of the filter element 146 can be further improved. In addition, through the cooperation of the at least two support members 1441, the lower surface of the noise reduction cover 144, and the filter element 146, the air intake space 1452 can be divided into several different sub-air intake spaces, thereby allowing airflow to enter different sub-air intake spaces.

[0035] When the above-mentioned at least two support members 1441 are arranged radially, the at least two support members 1441 are located at the outer periphery of the noise reduction connecting part 1443, and the support members 1441 are arranged radially.

[0036] In some embodiments, at least two support members 1441 are horizontally positioned at their upper ends, which ensures the balance of the filter element 146 at different positions and thus improves the stability of the filter element 146 installation. When the upper ends of different support members 1441 are horizontally positioned, the cross-sectional area of ​​the lower end of the noise reduction cover 144 gradually decreases along the direction perpendicular to the upper end of the noise reduction cover 144 to its lower end. As a result, the vertical distance between the support member 1441 and the lower end of the noise reduction cover 144 gradually increases from the outer periphery to the center of the noise reduction cover 144, thereby ensuring that the upper end of the support member 1441 is horizontally positioned.

[0037] Specifically, the upper end of the support member 1441 and the surface of the noise reduction connecting part 1443 are flush, which further ensures the balance of the filter member 146 at different positions.

[0038] In some embodiments, the support member 1441 includes at least one first sub-support member 14411 and at least one second sub-support member 14412. The number of first sub-support members 14411 may be, but is not limited to, one, two, or more than three. The number of second sub-support members 14412 may be, but is not limited to, one, two, or more than three. When there are multiple first sub-support members 14411 and multiple second sub-support members 14412, the first sub-support members 14411 and the second sub-support members 14412 are arranged at intervals; wherein, the multiple first sub-support members 14411 and the multiple second sub-support members 14412 are all radially arranged. For example, the first sub-support members 14411, the second sub-support members 14412, and the first sub-support members 14411 are arranged sequentially at intervals. Through the cooperation of at least one first sub-support member 14411 and at least one second sub-support member 14412, not only can the filter member 146 be supported, but different sub-intake spaces can also be formed, thereby increasing the airflow intake volume, etc.

[0039] Please continue reading Figures 1 to 4 In some embodiments, a filter space 1442 is recessed in the upper part of the noise reduction cover 144. A filter support portion 1444 is provided around the lower periphery of the noise reduction cover 144. The filter support portion 1444 can support the bottom edge of the filter element 146. The filter element 146 is embedded in the filter space 1442, and the bottom edge of the filter element 146 is located at the filter support portion 1444. Through the cooperation of the filter space 1442 and the filter support portion 1444 on the noise reduction cover 144, the filter element 146 and the like can be supported.

[0040] The filter element 146 can be supported by at least one of the filter support 1444, the noise reduction connecting part 1443, and the support member 1441. In this embodiment, the noise reduction cover 144 is provided with the filter support 1444, the noise reduction connecting part 1443, and the support member 1441, and all of the filter support 1444, the noise reduction connecting part 1443, and the support member 1441 serve to support the filter element 146.

[0041] In some embodiments, the filter element 146 is a sponge pad (not shown in the figure). The sponge pad can filter fine particles of dust, etc., is easy to replace, and is low in cost. The filter element 146 can also be other filter structures, which are not limited here.

[0042] In some embodiments, the power assembly 14 includes a safety valve (not shown in the figure). The safety valve is disposed on the noise reduction cover 144. The safety valve can be connected to the noise reduction cover 144 by means of, but not limited to, snap-fit, plug-in, or bolts. The safety valve can be disposed on the bottom surface of the noise reduction cover 144 or on the side of the noise reduction cover 144 opposite to the filter element 146. The safety valve is in an open-closed communication with the power chamber 1413. The safety valve has two states: open and closed. When the airflow in the dust cup assembly and the power assembly 14 is normal, the safety valve is in the closed state. When the dust cup assembly is full of dust, causing abnormal airflow, and the power assembly 14 is under negative pressure, the safety valve is in the open state, allowing airflow to enter the power chamber 1413, thereby dissipating heat from the power drive component 142 and reducing the risk of damage to the power drive component 142. The above-mentioned safety valve is a conventional component, and its operating principle will not be described in detail.

[0043] In some embodiments, a noise-reducing latching portion 1445 is provided at the top of the noise-reducing cover 144. The noise-reducing latching portion 1445 can be used to latch onto the bottom of the dust cup assembly. In addition, a noise-reducing protrusion 1446 is also provided at the top of the noise-reducing cover 144. The noise-reducing protrusion 1446 is at least partially a sidewall of the filter space 1442. The noise-reducing protrusion 1446 can be inserted into the bottom of the dust cup assembly, which not only facilitates the connection of the dust cup assembly to the power assembly 14, but also increases the filter space 1442 and improves the sealing performance to a certain extent.

[0044] The aforementioned filter space 1442, filter support 1444, noise reduction protrusion 1446, filter element 146, and noise reduction connecting part 1443 are all circularly arranged. Among them, the aforementioned support element 1441 is linearly arranged.

[0045] In some embodiments, the power shroud 141 includes a power shroud body 1411 and an air outlet plate 1412. The air outlet plate 1412 is detachably connected to the power shroud body 1411. The air outlet plate 1412 can be connected to the power shroud body 1411 by means of, but not limited to, snap-fit, plug-in, and bolts. An air outlet portion 14121 is disposed on the air outlet plate 1412. An air inlet portion 14111 is disposed at the upper end of the power shroud body 1411. The power shroud body 1411 and the air outlet plate 1412 together form the power cavity 1413.

[0046] Please see Figure 5 , Figure 5 This is a structural schematic diagram of an embodiment of the vacuum cleaner of this application. (In conjunction with...) Figures 1 to 4 This application provides a vacuum cleaner. The vacuum cleaner 10 includes a power component 14 and a dust cup assembly 16. The dust cup assembly 16 is detachably connected to and communicates with the power component 14. The dust cup assembly 16 can be connected to the power component 14 by, but is not limited to, snap-fit, plug-in, or bolt methods. The dust cup assembly 16 communicates with the power component 14. The filtered airflow from the dust cup assembly 16 flows into and out of the power component 14. It should be noted that the power component 14 in this embodiment is the same as the power component 14 described in the previous embodiments, and will not be repeated here.

[0047] The vacuum cleaner 10, through the combined action of the aforementioned power component 14 and dust cup component 16, not only forms a noise reduction space 1451 between the noise reduction cover 144 and the upper end of the power cover 141 in the power component 14, thereby reducing the noise of the power component 14 and improving the user experience; but also, the filter element 146 is disposed at the upper end of the noise reduction cover 144, which can further filter fine particles in the airflow, thereby improving filtration efficiency; at the same time, the noise reduction cover 144 can prevent some fine dust from directly entering the power cover 141, thereby reducing the risk of damage to the power drive component 142 and thus extending the service life of the power drive component 142.
