Description

Technical Field

[0001] The present invention relates to the technical field of dust and dirt separation device structures, and in particular to a dust cup assembly and a handheld vacuum cleaner. Background Art

[0002] Vacuum cleaners are commonly used household cleaning tools. With the development of technology, vacuum cleaners have evolved from traditional large devices to smaller devices that can be held by users.

[0003] The working principle of a vacuum cleaner is that there is an airflow generator inside the vacuum cleaner, which forms a lower air pressure inside the vacuum cleaner than at the air intake port, so that the air intake port of the vacuum cleaner has suction, thereby sucking dust and airflow into the vacuum cleaner together. There is a dust and pollution separation filter inside the vacuum cleaner to filter out the dust and pollution mixed in the airflow and return the clean air to the external environment.

[0004] The dust cup of a vacuum cleaner is the primary dust collector, requiring regular cleaning. Existing vacuum cleaners typically require opening the dust cup, then tilting the dust cup opening toward a trash bag to empty the dust. Some vacuum cleaners have complex dust cup opening mechanisms, requiring users to use both hands to open the dust cup. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the complicated dust cup dumping method of the vacuum cleaner in the prior art, thereby providing a dust cup assembly and a handheld vacuum cleaner.

[0006] A dust cup assembly, comprising:

[0007] A dust cup body, wherein a cleaning opening is provided at the bottom of the dust cup body;

[0008] A dust cup end cover movably connected to the cleaning opening;

[0009] A slider assembly, wherein the slider has a locking position close to the dust cup body and an unlocking position away from the dust cup body, and at least a portion of the dust cup end cover is located on the sliding path of the slider assembly.

[0010] The dust cup end cover is rotatably connected to the dust cup body.

[0011] The dust cup end cover comprises:

[0012] The end cover buckling part is located on the movement path of the sliding fastener, and the end cover buckling part is disengaged from the dust cup body when it moves in the movement direction of the sliding fastener.

[0013] The end cover buckle portion is provided with:

[0014] a transmission protrusion protruding toward the sliding path of the sliding fastener;

[0015] The sliding fastener comprises:

[0016] The sliding buckle limiting end is arranged upstream of the transmission protrusion.

[0017] The surface of the transmission protrusion facing the slider limiting end is an inclined transmission guide surface.

[0018] The sliding fastener is provided with:

[0019] A slide buckle limiting groove is provided, wherein the transmission protrusion is embedded in the slide buckle limiting groove.

[0020] The dust cup end cover comprises:

[0021] An end cover rotating portion, rotatably connected to the dust cup body;

[0022] The end cover torsion spring is arranged on the end cover rotating part.

[0023] The end cover buckle portion is provided with a dust cup locking protrusion protruding toward the outer wall of the dust cup body, and the outer wall of the dust cup body is provided with an end cover buckle.

[0024] The dust cup body is provided with:

[0025] The dust cup guide wall is arranged at the open end of the dust cup body toward the dust cup end cover. The dust cup guide wall bends into the dust cup body so that the cross-sectional area at the dust cup opening gradually decreases in the direction approaching the dust cup end cover.

[0026] The dust cup guide wall forms a clearance space on the side facing away from the dust collecting cavity inside the dust cup body.

[0027] The slider assembly further includes:

[0028] The slide buckle spring is arranged on the moving path of the slide buckle.

[0029] The sliding buckle part is provided with a sliding buckle touch groove.

[0030] A flange pad is provided in the sliding button touch groove.

[0031] A handheld vacuum cleaner comprising:

[0032] Host housing;

[0033] The dust cup assembly described in any of the above schemes is arranged on the main body shell, and the sliding fastener is slidably connected to the main body shell.

[0034] The host housing includes:

[0035] The power supply shell is connected to the host shell, and the sliding fastener is slidably connected to the power supply shell.

[0036] The technical solution of the present invention has the following advantages:

[0037] 1. The present invention provides a dust cup assembly, comprising: a dust cup body, wherein a cleaning opening is provided at the bottom of the dust cup body; a dust cup end cover, movably connected to the cleaning opening; a slider assembly, wherein the slider has a locking position close to the dust cup body and an unlocking position away from the dust cup body, and at least a portion of the dust cup end cover is located on the sliding path of the slider assembly.

[0038] A cleaning opening is provided at the bottom of the dust cup body, which can automatically drop out dust and dirt remaining in the dust collecting chamber when the dust cup end cover is opened. At least a portion of the dust cup end cover is located on the movement path of the sliding fastener. When the sliding fastener slides past the dust cup end cover, it pushes the connection portion between the dust cup end cover and the dust cup body to deform or displace, causing the end cover fastening portion to disengage from the dust cup body. Under the action of gravity, the dust cup end cover automatically opens, causing dust and dirt to automatically drop out, thus achieving one-touch control to open the dust cup and automatically dump the dust and dirt. The existing dust cup dumping method is complicated because the opening operation of some dust cups requires two-handed operation. Therefore, the dust cup cannot be kept facing downward when opened. After the dust cup is opened with both hands, the dust cup opening is turned toward the garbage dumping site for dust and dirt cleaning. When emptying the dust cup of this solution, you only need to align the opening of the dust cup with the garbage dumping location when opening the cover, and then control the sliding buckle assembly to slide with one button to automatically open the dust cup end cover. Therefore, the operation of opening the dust cup end cover and the operation of aligning the dust cup end cover with the garbage dumping location can be performed at the same time, and the user can open the dust cup end cover with one hand with one button, which improves the convenience of the user's operation of dumping dust in the dust cup and improves the user experience.

[0039] 2. The dust cup assembly provided by the present invention has the dust cup end cover rotatably connected to the dust cup body.

[0040] When the connection between the dust cup end cover and the dust cup body is pushed and disengaged by the sliding fastener, the dust cup end cover automatically rotates and opens under the influence of the gravity of the dust cup end cover.

[0041] 3. The dust cup assembly provided by the present invention, the dust cup end cover includes: an end cover buckling portion, the end cover buckling portion is located on the movement path of the sliding fastener, and the end cover buckling portion disengages from the dust cup body when moving in the movement direction of the sliding fastener.

[0042] When the end cover buckle is buckled on the opening at the bottom of the dust cup body, the end cover buckle is located on the movement path of the sliding fastener. When the sliding fastener slides past the end cover buckle, it pushes the end cover buckle to deform or displace, causing the end cover buckle to disengage from the dust cup body. Under the action of gravity, the dust cup end cover rotates downward to open, so that the dust and dirt fall off automatically, realizing one-button control to open the dust cup and automatically dump the dust and dirt.

[0043] 4. The dust cup assembly provided by the present invention has a transmission protrusion on the end cover fastening portion, and the transmission protrusion protrudes toward the sliding path of the slider; the slider includes a slider limiting end, which is provided upstream of the transmission protrusion.

[0044] A gap is formed between the transmission protrusion and the outer wall of the dust cup body to accommodate the sliding buckle limiting end. During the movement of the sliding buckle limiting end toward the unlocking position, it comes into contact with the transmission protrusion and further pushes the transmission protrusion to drive the end cover buckle part to unlock.

[0045] 5. In the dust cup assembly provided by the present invention, the surface of the transmission protrusion facing the sliding buckle limiting end is an inclined transmission guide surface.

[0046] The pneumatic guide surface can play a guiding role in the process of the slider sliding to the right. In this embodiment, the end cover buckle is made of a material with a certain elastic deformation ability such as metal or plastic. While the end cover buckle is pushed to the right by the slider, it can also rotate and deform to the right as a whole under the guidance of the inclined surface, thereby making it more conducive to the smooth disengagement and unlocking of the end cover buckle.

[0047] 6. The dust cup assembly provided by the present invention is provided with a slide buckle limiting groove on the slide buckle member, and the transmission protrusion is embedded in the slide buckle limiting groove.

[0048] The groove walls of the sliding buckle limiting groove can be limited respectively upstream and downstream of the transmission protrusion.

[0049] 7. The dust cup assembly provided by the present invention, the dust cup end cover includes: an end cover rotating part, which is rotatably connected to the dust cup body; and an end cover torsion spring, which is arranged on the end cover rotating part.

[0050] When the dust cup end cover is in the closed state, the end cover torsion spring is in an elastic deformation state. After the user controls the sliding fastener to slide and unlock, the dust cup end cover automatically pops open under the drive of the end cover torsion spring, further improving the convenience of one-button operation for the user.

[0051] 8. The dust cup assembly provided by the present invention is provided with: a dust cup guide wall on the dust cup body, which is provided at the open end of the dust cup body toward the dust cup end cover, and the dust cup guide wall bends into the dust cup body so that the cross-sectional area at the dust cup opening gradually decreases in the direction approaching the dust cup end cover.

[0052] The guide wall forms an arc-shaped guide surface on the side facing the dust collecting chamber. After the dust cup end cover is opened, the dust inside the dust collecting chamber slides along the guide wall, and the cross-sectional area of ​​the guide wall gradually decreases in the direction close to the bottom opening of the dust cup body, so that the dust tends to gather toward the center of the dust cup opening during the falling process, preventing the dust from spreading during the falling process.

[0053] 9. The dust cup assembly provided by the present invention further comprises a slider spring, which is arranged on the moving path of the slider.

[0054] The slider spring not only improves user feedback during manipulation, but also automatically resets the slider after manipulation. After the slider resets, the slider's slider limiter returns to the locked position. When the dust cup end cap reengages the opening at the bottom of the dust cup body, the end cap's locking portion returns to the downstream position of the slider. The downstream position of the slider is based on the direction of movement of the slider from the locked position to the unlocked position.

[0055] 10. In the dust cup assembly provided by the present invention, a flange pad is provided in the sliding touch groove.

[0056] The flange pad can increase the contact area between the user and the slider, and can also increase the force area when the user controls the slider, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0088] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0089] Example 1

[0090] This embodiment provides a handheld vacuum cleaner, such as Figure 1 - Figure 3 As shown, it includes: a main body shell a; an airflow generator, which is arranged in the main body shell a, and is used to form a negative pressure in the main body shell a, and a channel for airflow is formed between the airflow generator and the main body shell a; a dust and dirt separator, which is arranged in the main body shell a, and is located between the airflow generator and the main body shell a, and the dust and dirt separator is arranged to surround the airflow generator. When the dust and dirt separator surrounds the airflow generator, the height of the airflow generator and the height of the dust and dirt separator partially overlap, so the total height of the dust and dirt separator and the airflow generator after assembly is less than the sum of the heights of the dust and dirt separator and the airflow generator. Compared with the airflow generator and dust and dirt separator arranged separately in the prior art, the height of the main body shell a can be significantly reduced.

[0091] Specifically, such as Figure 2 、 Figure 5 、 Figure 6 As shown, the air flow generator is used to generate negative pressure, such as Figure 1 As shown, the left side of the main body housing a has an air inlet component d3, and the air flows into the handheld vacuum cleaner from the air inlet component d3. Figure 1 The main unit of the handheld vacuum cleaner is shown in the figure. The main unit is used to separate the airflow entering the main unit from the dust mixed in the airflow, and then discharge the clean airflow. Figure 1 The air inlet assembly d3 shown can be equipped with a variety of suction heads. For user convenience, the air inlet assembly d3 can be equipped with a connecting tube assembly h, and then a variety of suction heads can be assembled through the connecting tube assembly h, thereby extending the length of the suction head to the main body of the handheld vacuum cleaner, making it easier for users to clean high, far, or low locations, and adapt different suction heads to clean dust and impurities in corners and crevices. In this embodiment, the negative pressure generated by the airflow generator refers to a pressure lower than that at the air inlet assembly d3, thereby generating suction at the air inlet assembly d3, drawing the mixture of airflow, dust, and impurities into the handheld vacuum cleaner.

[0092] Further, combined Figure 4 、 Figure 5 The airflow generator is arranged in the encirclement of the dust separator, and the airflow generator and the dust separator have a certain range of overlap in the height direction, thereby reducing the total height of the airflow generator and the dust separator after assembly. In addition, the airflow generator is located inside the dust separator, making the assembly structure between the airflow generator and the dust separator more compact, further reducing the volume of the main body part of the handheld vacuum cleaner.

[0093] In this embodiment, Figure 2 - Figure 8 As shown, the airflow generator is a vacuum motor c1, which generates negative pressure when it works. Figure 6 As shown, the vacuum motor C1 is located in the middle of the dust separator. Under the drive of the vacuum motor C1, an airflow is formed from the dust separator to the vacuum motor C1. Figure 3 、 Figure 6 The dust separator is located between the main body housing a and the vacuum motor c1. There is a chamber with a circular cross section between the main body housing a and the vacuum motor c1. In this embodiment, the vacuum motor c1 is embedded in the middle of the dust separator. The vacuum motor c1 and the dust separator form an integral structure. After the airflow enters the main body housing a, an airflow is formed in the integral structure of the vacuum motor c1 and the dust separator, flowing from the outer ring of the circular chamber to the middle vacuum motor c1.

[0094] On the basis of the above embodiment, as a further limited embodiment, Figure 6As shown, the airflow generator is located downstream of the dust separator. The airflow mixed with dust and impurities first passes through the dust separator to separate the dust and impurities from the airflow, and then the clean airflow enters the airflow generator, which can protect the airflow generator and prevent dust accumulation.

[0095] Specific, combined Figure 1 - Figure 3 、 Figure 6 As shown, driven by the vacuum motor c1, the airflow enters the main body housing a from the bottom of the airflow generator and the dust separator, as shown in FIG. Figure 6 As shown, the airflow enters from the bottom of the dust separator and then flows out from the top of the dust separator. Then the airflow flows from the outer dust separator to the inner airflow generator, enters from the top of the airflow generator, and then is discharged from the bottom of the airflow generator, forming a deflection motion route from bottom to top, from the outer circle to the middle, and then from top to bottom.

[0096] On the basis of the above embodiment, as a further limited embodiment, Figure 6 As shown, the central axis of the airflow generator and the dust separator are co-linear. The combination of the airflow generator and the dust separator is more compact, further reducing the space occupied by the overall structure of the dust separator and the airflow generator.

[0097] Specifically, such as Figure 5 、 Figure 6 As shown, the vacuum motor C1 can be considered a cylinder. The dust separator has a cylindrical chamber at its center, and the vacuum motor C1 fits neatly into the cylindrical chamber in the middle of the dust separator. Alternatively, the central axes of the dust separator and the vacuum motor C1 are parallel. Alternatively, the central axes of the dust separator and the vacuum motor C1 intersect.

[0098] On the basis of the above embodiment, as a further limited embodiment, Figure 6 - Figure 8 As shown, the dust separator includes: a motor housing c2, located within the main unit housing a; the airflow generator located within the motor housing c2; and an air guide cone c203 located between the motor housing c2 and the main unit housing a. The motor housing c2 forms a chamber for embedding the vacuum motor c1. The air guide cone c203 is located outside the motor housing c2 and surrounds the vacuum motor c1.

[0099] Specifically, such as Figure 6 - Figure 8 As shown, the cross-sectional area of ​​the air guide cone c203 gradually increases along the flow direction of the airflow, and the bottom opening of the air guide cone c203 is relatively small. Figure 6As shown, airflow enters from the bottom of each guide cone c203 and flows along the inner wall of the guide cone c203 toward the larger outlet at the top of the guide cone c203. The airflow rises in a spiral shape, following the inner wall of the guide cone c203. During this rise, the inner diameter of the guide cone c203 gradually increases, further separating the remaining dust and impurities in the airflow. By the time the airflow spirals up to the top of the guide cone c203, the airflow has been further separated from the dust and impurities. The clean air continues to flow above the vacuum motor c1, then enters the top of the vacuum motor c1 and flows out from the lower half of the vacuum motor c1.

[0100] Among them, such as Figure 6 - Figure 8 As shown, the bottom of the motor housing c2 has an opening for embedding the power supply motor, and the bottom of the motor housing c2 is equipped with a motor base c3, which closes the opening at the bottom of the motor housing c2 and fixes the vacuum motor c1 in the chamber formed between the motor housing c2 and the motor base c3.

[0101] Further, such as Figure 6 As shown, the surface of the motor base c3 facing outward is an arc surface, that is, Figure 6 The lower surface of the motor base C3 is an arc surface, combined with Figure 1 - Figure 3 The motor housing (c2) and motor base (c3) are located within the overall housing. Airflow entering from below the dust separator is guided by the arc-shaped outer surface of the motor base (c3) and flows toward the smaller opening at the bottom of the air guide cone (c203). The opening at the bottom of the air guide cone (c203) surrounds the edge of the arc-shaped surface of the motor base (c3), allowing airflow to more easily enter the air guide cone (c203) for further dust removal and separation.

[0102] On the basis of the above embodiment, as a further limited embodiment, Figure 6 - Figure 8 As shown, the cross-sectional area of ​​the air guide cone c203 gradually increases along the direction of airflow. The air guide cone c203 includes a lateral air outlet c2031 located on the sidewall of the air guide cone c203, near the top of the air guide cone c203. As the airflow rises from the bottom of the air guide cone c203 along the inner wall of the air guide cone c203, it flows out laterally at the lateral air outlet c2031 on the sidewall of the air guide cone c203. This prevents the airflow from rising further after reaching the height of the air inlet at the top of the motor housing c2.

[0103] On the basis of the above embodiment, as a further limited embodiment, Figure 5 、 Figure 6As shown, the motor housing c2 includes a motor combing port c201 located at the top of the motor housing c2 and a motor air outlet c205 located in the lower half of the motor housing c2. This allows airflow to form a zigzag path in the height direction within the main housing a. While the airflow forms a zigzag path, the noise generated during the movement along the zigzag path is partially offset by noise reflection, thereby reducing the noise level.

[0104] Specifically, in Figure 6 From the perspective, the edge of the left side of the air guide cone c203 on the left side of the motor is an inclined line, and the right side of the air guide cone c203 is fitted with the outer surface of the motor housing c2, that is, as the inner diameter of the air guide cone c203 gradually increases from bottom to top, the air guide cone c203 as a whole tilts, and the tilt direction is away from the vacuum motor c1. Figure 6 From the perspective, the air guide cone c203 on the left is tilted to the left away from the vacuum motor c1, causing the air flow to flow along the inner wall of the air guide cone c203, and the distance away from the central axis of the vacuum motor c1 to increase more and more, thereby further improving the air guide cone c203's ability to separate dust and impurities.

[0105] The motor air vent c201 is an opening formed at the top of the motor housing. The specific structure of the motor air vent c201 is not limited. In this embodiment, the motor air vent c201 is a circular opening extending through the top of the motor housing c2. Alternatively, the motor air vent c201 may be an array of openings formed by a plurality of opening units.

[0106] Furthermore, the opening edge of the motor combing air outlet c201 is provided with an arc-shaped airflow guiding surface, which can guide the airflow entering the motor housing.

[0107] On the basis of the above embodiment, as a further limited embodiment, Figure 6As shown, the height of the motor combing air outlet c201 does not exceed the height of the side air outlet c2031. Since the air guide cone c203 is arranged around the vacuum motor c1, the motor combing air outlet c201 on the top of the vacuum motor c1 is surrounded by the air guide cone c203. Since the height of the motor combing air outlet c201 is relatively lower than the side air outlet c2031, a groove-shaped space surrounded by the air guide cone c203 is formed above the motor combing air outlet c201. The first filter c7 can be further installed in the groove-shaped space. The first filter c7 can further filter and purify the airflow before it enters the vacuum motor c1. In addition, the vacuum motor c1 and the air guide cone c203 are originally components installed in the entire machine housing. The new installation structure formed by the components makes the assembly between the components more compact, further reducing the volume of the main body of the handheld vacuum cleaner. As an alternative embodiment, the height of the motor air outlet is the same as the height of the side air outlet c2031. As another alternative embodiment, the height of the motor air outlet is higher than the height of the lateral air outlet c2031.

[0108] On the basis of the above embodiment, as a further limited embodiment, Figure 6 - Figure 8 As shown, the air guide cone c203 further includes: lateral air guide blades c2032, which are provided at the opening edge of the lateral air outlet c2031 and are tangent to the inner wall of the air guide cone c203. The lateral air guide blades c2032 can guide the direction of airflow out of the air guide cone c203.

[0109] Specifically, such as Figure 8 As shown, the inclination directions of adjacent side air guide blades c2032 are different. Figure 8 From the perspective, observe the lateral air guide blades on each air guide cone c203 in the counterclockwise direction. There is a uniform tilt angle change between adjacent lateral air guide blades in the counterclockwise direction. Figure 8 In this state, looking down at the motor housing c2 from above, the top opening of the air guide cone c203 is facing. At this time, when the air flows out from the side air outlets c2031 of multiple air guide cones c203, a counterclockwise rotating cyclone is formed under the guidance of the side air guide blades, making the airflow entering from various places around the motor comb air outlet c201 more uniform.

[0110] Furthermore, the lateral air guide blades do not directly point to the motor combing air outlet c201, so that the air flow flowing out from the lateral air outlet c2031 is evenly mixed before entering the motor combing air outlet c201, making the air flow entering the motor combing air outlet c201 more uniform.

[0111] In this embodiment, a combing grille is provided on the motor housing c2 at a position corresponding to the motor combing air outlet c201. The cyclone formed by the air flowing out of the air guide cone c203 and guided by the lateral air guide vanes passes through the combing grille and enters the motor combing air outlet c201 more evenly.

[0112] On the basis of the above embodiment, as a further limited embodiment, Figure 3 、 Figure 6 As shown, the motor air outlet c205 is located on the side of the airflow generator, and the motor housing c2 is provided with a motor air outlet channel c204 extending from the motor air outlet c205 away from the motor air outlet c205. The airflow within the vacuum motor c1 flows downward from the top of the vacuum motor c1. Therefore, the motor air outlet c205 is located on the side wall of the vacuum motor c1, and the motor air outlet channel c204 extends away from the motor air outlet c205. As the airflow moves downward within the vacuum motor c1, it turns at the motor air outlet c205, further bending the airflow path, further increasing noise reflection and reducing noise.

[0113] On the basis of the above embodiment, as a further limited embodiment, Figure 6 As shown, the height of the airflow in the motor air outlet channel c204 gradually increases, so that the flow path of the airflow after flowing out of the air outlet bends toward the top of the vacuum motor c1, further increasing noise reflection and reducing noise.

[0114] On the basis of the above embodiment, as a further limited embodiment, Figure 6 As shown, the motor housing c2 is provided with a motor exhaust port c2022, which is connected to the motor air outlet channel c204 and is at a height not less than that of the motor combing port c201. The fact that the motor exhaust port c2022 is at a height not less than that of the motor combing port c201 indicates that the airflow, after flowing out of the lower half of the vacuum motor c1, bends toward the top of the vacuum motor c1. This not only increases noise reflection and reduces noise, but also lengthens the overall air duct. Noise energy is dissipated within the air duct, and the overall air duct length is lengthened, increasing the amount of noise energy dissipated, thereby reducing the overall operating noise of the handheld vacuum cleaner. As an alternative embodiment, the height of the motor exhaust port c2022 is lower than that of the motor combing port c201.

[0115] On the basis of the above embodiment, as a further limited embodiment, Figure 3 、 Figure 6As shown, the motor housing c2 includes a motor exhaust duct c202 located downstream of the motor outlet duct c204. The motor exhaust port c2022 is located on the motor exhaust duct c202. The motor exhaust duct c202 further extends the overall air duct and forms a new turning angle with the motor exhaust duct c202, further bending the airflow path and thereby further dissipating noise energy.

[0116] In this embodiment, the horizontally arranged motor exhaust duct intersects with the inclined motor air outlet channel c204, and the air flow turns when passing through the connection portion between the motor exhaust duct and the motor air outlet channel c204.

[0117] On the basis of the above embodiment, as a further limited embodiment, Figure 3 、 Figure 6 As shown, the motor exhaust channel c202 is provided with an exhaust sponge c2021, which is located upstream of the motor exhaust port c2022. The exhaust sponge c2021 can further filter the air before it flows out of the motor exhaust port c2022.

[0118] Specifically, in this embodiment, Figure 4 As shown, the motor exhaust channel c202 is cylindrical with a circular cross section. The motor exhaust channel c202 is evenly distributed with motor exhaust ports c2022. Figure 5 、 Figure 7 、 Figure 8 As shown, a cylindrical exhaust sponge c2021 is provided in the motor exhaust channel c202, and filter holes are distributed on the exhaust sponge c2021. As an alternative embodiment, the cross section of the motor exhaust channel is a triangle, rectangle, pentagon, hexagon or other polygon. As another alternative embodiment, the cross section of the motor exhaust channel is an ellipse. Figure 7 、 Figure 8 As shown, the motor exhaust duct c202 consists of two detachable parts. One part is integrally molded into the motor housing, forming a motor outlet duct c204 that exhausts air to the right. The motor outlet duct c204 is open at the top and is closed by a duct cover c206, forming the motor exhaust duct c202 to the right of the motor outlet duct c204. The exhaust sponge c2021 can be cleaned or replaced by opening the duct cover c206. In this embodiment, the duct structure forming the motor outlet duct c204 is welded to the right opening of the motor housing c2, which serves as the motor outlet c205.

[0119] On the basis of the above embodiment, as a further limited embodiment, Figure 2、 Figure 3 As shown, a second filter a103 is installed between the motor air outlet c205 and the motor exhaust port c2022 of the motor housing c2, or downstream of the motor exhaust port c2022. After exiting the motor exhaust port c2022, the airflow enters the space between the overall housing and the motor exhaust duct c202. The second filter a103, located between the overall housing and the exhaust duct, further purifies the airflow before exiting the vacuum cleaner.

[0120] On the basis of the above embodiment, as a further limited embodiment, Figure 1 - Figure 3 As shown, the handheld vacuum cleaner also includes a dust cup assembly d, comprising a dust cup body d1, located upstream of the dust separator; and a dust cup filter d2, located within the dust cup assembly d. Airflow drawn into the vacuum cleaner first passes through the dust cup assembly d, where it is acted upon by the dust and dirt separation force of the dust cup filter d2, before entering the dust separator for further purification.

[0121] Specifically, such as Figure 1 - Figure 3 As shown, the dust cup body d1 is a cylindrical shape with an opening at the top. There is a dust collecting chamber d4 inside the dust cup body d1. The dust and dirt separator is installed on the opening at the top of the dust cup body d1. The side wall of the dust cup body d1 has an air inlet assembly d3. The air flow is sucked into the dust collecting chamber d4 from the air inlet assembly d3. After the dust and dirt are separated in the dust collecting chamber d4, the air flow rises and enters the dust and dirt separator under the drive of the air flow generator.

[0122] The dust removal structure of the dust cup assembly d, such as Figure 1 - Figure 3 、 Figure 12 、 Figure 19 As shown, the portion of the air inlet assembly d3 that is connected to the dust cup body d1 is tangent to the dust cup body d1, thereby forming a lateral air inlet path tangent to the inner wall of the dust cup body d1.

[0123] Specifically, a dust cup filter d2 is provided in the dust collecting chamber d4. Figure 2 From the perspective, the top opening edge of the dust collecting chamber d4 has an annular flange extending into the dust collecting chamber d4, and the dust cup filter d2 is connected to the annular flange. A cyclone separation space is formed between the dust cup filter d2 and the inner wall of the dust cup body d1. Since the top of the cyclone separation space is blocked by the annular flange, the airflow can only move to the middle of the dust collecting chamber d4 through the dust cup filter d2.

[0124] like Figure 3As shown, the movement route of the airflow in the dust collecting chamber d4 is that the airflow enters the dust collecting chamber d4 from the side of the dust cup body d1 in a tangential manner to the inner wall of the dust cup, and the airflow moves in a circular motion along the inner wall of the dust collecting chamber d4. The dust and impurities mixed in the airflow only fit the inner wall of the dust collecting chamber d4 during the circular motion. The airflow moves upward under the drive of the vacuum motor c1, and the annular flange for fixing the filter screen blocks the rising airflow and guides the airflow, so that the airflow moves toward the dust cup filter screen d2 under the drive of the vacuum motor c1, and the dust cup filter screen d2 can further filter the airflow.

[0125] On the basis of the above embodiment, as a further limited embodiment, Figure 6 As shown, the dust cup assembly d further includes: a dust cup inner cylinder d10, a dust cup clean air duct is formed between the dust cup inner cylinder d10 and the dust cup filter d2, and the outlet of the dust cup clean air duct is connected to the dust separator.

[0126] The dust cup contents are located in the annular space surrounded by the dust cup filter d2. A dust cup clean air duct is formed between the dust cup contents and the dust cup filter d2. After the airflow passes through the purification effect of the cyclone separation space, it is further purified by the dust cup filter d2, and then moves toward the dust separator above in the dust cup clean air duct.

[0127] Specifically, such as Figure 2 、 Figure 3 、 Figure 13 As shown, the bottom opening of the dust separator is assembled on the opening at the top of the dust cup body d1. Since the motor base c3 in the dust separator has an outwardly protruding arc surface, when the dust separator is assembled on the dust cup body d1, the motor base c3 extends into the dust cup body d1. Furthermore, the dust cup body d1 has a dust cup inner cylinder d10. The motor base c3 is embedded in the top opening of the dust cup inner cylinder d10 and seals the top of the dust cup inner cylinder d10. The dust cup inner cylinder d10 and the dust cup filter d2, as well as the dust cup inner cylinder d10 and the annular flange for mounting the filter, form a channel for the air flow to rise. The airflow mixed with dust and dirt undergoes dust and dirt separation in the dust collecting chamber d4, so most of the dust and dirt accumulates in the dust collecting chamber d4.

[0128] On the basis of the above embodiment, as a further limited embodiment, Figure 12 - Figure 16 As shown, the bottom of the dust cup body d1 is provided with a cleaning opening, and the cleaning opening is movably connected to the dust cup end cover d8. The cleaning opening is provided at the bottom of the dust cup body d1, and the dust and dirt retained in the dust collecting chamber d4 can be automatically removed when the dust cup end cover d8 is opened.

[0129] Specifically, such as Figure 13 、 Figure 16As shown, the dust cup end cap d8 is rotatably connected to the dust cup body d1. As an alternative embodiment, the dust cup end cap d8 is slidably connected to the dust cup body d1. As another alternative embodiment, the dust cup end cap d8 is fastened to the opening at the bottom of the dust cup body d1 through a snap structure.

[0130] On the basis of the above embodiment, as a further limited embodiment, Figure 12 、 Figure 15 、 Figure 18 As shown, the handheld vacuum cleaner also includes: a sliding buckle assembly d9, including a sliding buckle part d901, and the sliding buckle part d901 is movably connected to the handheld vacuum cleaner; the dust cup end cover d8 includes: an end cover buckling part d802, and the end cover buckling part d802 is located on the movement path of the sliding buckle part d901, and the end cover buckling part d802 disengages from the dust cup body d1 when it moves in the movement direction of the sliding buckle part d901. When the end cover buckle part d802 is buckled on the opening at the bottom of the dust cup body d1, the end cover buckle part d802 is located on the movement path of the sliding fastener d901. When the sliding fastener d901 slides past the end cover buckle part d802, it pushes the end cover buckle part d802 to deform or displace, so that the end cover buckle part d802 is disengaged from the dust cup body d1. Under the action of gravity, the dust cup end cover d8 rotates downward to open, so that the dust and dirt fall off automatically, realizing one-button control to open the dust cup and automatically dump the dust and dirt.

[0131] Specific, combined Figure 13 、 Figure 15 The left side of the end cover fastening part d802 is rotatably connected to the left side of the opening at the bottom of the dust cup body d1, and the right side of the end cover fastening part d802 is fastened to the outer wall on the right side of the opening at the bottom of the dust cup body d1. The sliding fastener d901 is located between the end cover fastening part d802 and the side wall of the dust cup body d1. At this time, when the sliding fastener d901 slides to the right, it pushes the end cover fastening part d802 to the right, thereby disengaging from the outer wall of the dust cup body d1. Figure 15 As shown, the sliding fastener d901 is slidably connected to the power supply housing f101. Figure 13 From the perspective, a sliding buckle groove f1011 is provided on the bottom surface of the power supply housing f101, and the sliding buckle part d901 is slidably connected in the sliding buckle groove f1011.

[0132] Among them, such as Figure 13 、 Figure 16 As shown, an end cover sealing protrusion d805 is provided on the side of the dust cup end cover d8 facing the dust collecting chamber d4. The end cover sealing protrusion d805 is embedded in the bottom opening of the dust cup inner cylinder d10, and when the dust cup end cover d8 is buckled closed, the end cover sealing protrusion d805 just closes the bottom opening of the dust cup inner cylinder d10, so that an annular cyclone separation space is formed between the dust cup inner cylinder d10 and the inner wall of the dust cup.

[0133] On the basis of the above embodiment, as a further limited embodiment, Figure 15 、 Figure 16 As shown, the sliding fastener d901 is slidably connected to the handheld vacuum cleaner, and the sliding fastener d901 has a locking position close to the dust cup body d1 and an unlocking position away from the dust cup body d1.

[0134] like Figure 15 As shown, the locking position of the slider d901 is the position where the slider d901 is located between the end cover fastening portion d802 and the outer wall of the dust cup body d1, and the unlocking position of the slider d901 is the position where the slider d901 slides to the right and pushes open the end cover fastening portion d802.

[0135] There is no specific limitation on the structure of the dust cup inner cylinder d10. In this embodiment, Figure 2 、 Figure 13 、 Figure 15 As shown, the dust cup inner barrel d10 includes an inner barrel air guide section d1001 and an inner barrel extension section d1002. The inner barrel air guide section d1001 is located within the encirclement of the dust cup filter d2. After the airflow is purified and separated between the inner wall of the dust collecting chamber d4 and the dust cup filter d2, the airflow passes through the dust cup filter d2 and enters the space between the dust cup filter and the dust cup inner barrel d10. Because the vacuum motor c1 creates a negative pressure above the dust collecting chamber d4, the airflow, after passing through the dust cup filter d2, rises along the inclined inner barrel air guide section d1001 and then enters the air guide cone c203. The inner barrel air guide section d1001 forms a seal toward the side of the motor base d3. The inner barrel extension section d1002 further extends toward the dust cup end cap d8 at the bottom of the dust cup and is sealed by the end cap sealing protrusion d805 on the dust cup end cap d8.

[0136] On the basis of the above embodiment, as a further limited embodiment, Figure 15 As shown, the end cap fastening portion d802 is provided with a transmission protrusion d8022 that protrudes into the sliding path of the slider d901. The slider d901 includes a slider limit end d903 that is located upstream of the transmission protrusion d8022. A gap is formed between the transmission protrusion d8022 and the outer wall of the dust cup body d1 to accommodate the slider limit end d903. As the slider limit end d903 moves toward the unlocked position, it contacts the transmission protrusion d8022, further pushing the transmission protrusion d8022 to unlock the end cap fastening portion d802.

[0137] On the basis of the above embodiment, as a further limited embodiment, Figure 15 As shown, the surface of the transmission protrusion d8022 facing the slider limit end d903 is an inclined transmission guide surface d8023.

[0138] Specifically, such as Figure 15 As shown, the transmission guide surface d8023 can play a guiding role in the process of the slider sliding to the right. In this embodiment, the end cover buckle d802 is made of a material with a certain elastic deformation ability such as metal or plastic. While the end cover buckle d802 is pushed to the right by the slider, it can also be guided by the inclined surface to make the end cover buckle d802 rotate to the right as a whole, thereby making it easier for the end cover buckle d802 to be smoothly disengaged and unlocked.

[0139] On the basis of the above embodiment, as a further limited embodiment, Figure 15 、 Figure 18 As shown, the slide buckle d901 is provided with a slide buckle limiting groove, and the transmission protrusion d8022 is embedded in the slide buckle limiting groove. The groove wall of the slide buckle limiting groove can limit the upstream and downstream of the transmission protrusion d8022 respectively. Figure 15 As shown, the sliding buckle limit grooves form limits on the left and right sides of the transmission protrusion d8022 respectively.

[0140] Furthermore, the sliding buckle d901 is provided with a sliding buckle limiting groove d906, and the transmission protrusion d8022 is embedded in the sliding buckle limiting groove d906.

[0141] On the basis of the above embodiment, as a further limited embodiment, Figure 14 As shown, the dust cup end cover d8 includes: an end cover rotating portion d801, which is rotatably connected to the dust cup body d1; and an end cover torsion spring d8011, which is provided on the end cover rotating portion d801. When the dust cup end cover d8 is in the closed state, the end cover torsion spring d8011 is in an elastically deformed state. After the user controls the sliding fastener d901 to slide and unlock, the dust cup end cover d8 automatically opens under the elastic force of the end cover torsion spring d8011, further improving the convenience of one-touch operation for the user.

[0142] On the basis of the above embodiment, as a further limited embodiment, Figure 15 、 Figure 17 As shown, the dust cup end cover d8 also includes: an end cover buckling portion d802, and the end cover buckling portion d802 has a dust cup locking protrusion d803 protruding toward the outer wall of the dust cup body d1; the outer wall of the dust cup body d1 is provided with an end cover buckle d8021.

[0143] On the basis of the above embodiment, as a further limited embodiment, Figure 14 、 Figure 15As shown, the dust cup body d1 is provided with a dust cup guide wall d804, which is provided at the open end of the dust cup body d1 facing the dust cup end cover d8. The dust cup guide wall d804 bends inwardly toward the dust cup body d1, causing the cross-sectional area of ​​the dust cup opening to gradually decrease as it approaches the dust cup end cover d8. The guide wall forms an arc-shaped guide surface on the side facing the dust collecting chamber d4. After the dust cup end cover d8 is opened, dust and dirt inside the dust collecting chamber d4 slide down along the guide wall, and the cross-sectional area of ​​the guide wall gradually decreases as it approaches the bottom opening of the dust cup body d1. As a result, the dust and dirt tend to gather toward the center of the dust cup opening during its falling process, preventing it from spreading during its falling process.

[0144] On the basis of the above embodiment, as a further limited embodiment, Figure 14 、 Figure 15 As shown, the dust cup guide wall d804 forms a clearance space on the side facing away from the dust collecting cavity d4 inside the dust cup body d1.

[0145] Specifically, such as Figure 14 As shown, the portion of the guide wall facing the left side forms a space for accommodating the end cover rotating part d801 with the dust cup body d1, and the space is combined with the dust cup body d1. Figure 17 The rotating part of the end cover and the end cover torsion spring d8011 provided on the end cover rotating part d801 are both installed in the clearance space formed by the guide wall, making the overall shape of the device more regular. Figure 15 As shown, the portion of the guide wall facing the right side forms a space for accommodating the end cover snap-fit ​​portion d802, making the overall shape of the device more regular.

[0146] On the basis of the above embodiment, as a further limited embodiment, Figure 13 、 Figure 16 As shown, the slider assembly d9 also includes: a slider spring d902, which is arranged on the moving path of the slider d901. The slider spring d902 can improve the acceptance feedback during user manipulation on the one hand, and can automatically reset after user manipulation on the other hand. After the slider d901 is reset, the slider limit end d903 of the slider d901 returns to the locked position, and when the dust cup end cover d8 is re-fastened on the opening at the bottom of the dust cup body d1, the end cover fastening part d802 returns to the downstream position of the slider d901. The downstream of the slider d901 is based on the movement direction of the slider d901 from the locked position to the unlocked position.

[0147] On the basis of the above embodiment, as a further limited embodiment, Figure 18 As shown, the sliding buckle d901 is provided with a sliding buckle touch groove d904. The sliding buckle touch groove d904 facilitates the user to operate the sliding buckle d901.

[0148] On the basis of the above embodiment, as a further limited embodiment, Figure 18 As shown, a flange pad d905 is provided in the sliding buckle touch groove d904. The flange pad d905 can increase the contact area between the user and the sliding buckle d901, and also increase the force area when the user controls the sliding buckle d901, thereby improving the user experience.

[0149] On the basis of the above embodiment, as a further limited embodiment, Figure 1 As shown, the handheld vacuum cleaner further includes: a handle assembly b, which is provided on the main body shell a; the main body shell a includes: an entire machine exhaust port a102, and the entire machine exhaust port a102 is provided in any direction on both sides of the handle assembly b.

[0150] Specifically, such as Figure 1 As shown, the main body of the handheld vacuum cleaner is composed of a dust cup assembly d at the bottom, a suction assembly c located on the dust cup assembly d, and a vacuum motor c1 in the suction assembly c to provide power for the suction function of the whole machine. Figure 1 、 Figure 3 、 Figure 4 The motor housing c2 has a motor air outlet channel c204 extending obliquely to the right, and a motor exhaust channel c202 connected to the downstream of the motor air outlet channel c204. Therefore, the main body housing a has a lateral protrusion a104 protruding to the right.

[0151] Furthermore, the lateral raised portion a104 is provided with an exhaust port a102 for the entire machine. The exhaust port a102 for the entire machine is arranged to face the side, thereby avoiding exhausting air directly toward the user, thereby improving the user experience.

[0152] Specifically, such as Figure 1 、 Figure 19 、 Figure 20 As shown, the opening of the air inlet assembly d3 faces the part that needs to be cleaned. Figure 20 From the perspective of , the steam rack exhaust vent exhausts air to both sides of plane Y-Y.

[0153] On the basis of the above embodiment, as a further limited embodiment, Figure 1 -3. Figure 19 As shown, the handheld vacuum cleaner further includes: a power supply assembly f, including a power supply housing f101, one end of the power supply housing f101 is connected to the main body housing a, and the other end extends parallel to the lateral protrusion a104.

[0154] On the basis of the above embodiment, as a further limited embodiment, Figure 1 As shown, the handle assembly b connects the lateral protrusion a104 and the power supply assembly f. Specifically, as Figure 3 As shown, the power supply assembly f has circuit elements, and the handle assembly b has an installation space inside, so that the control end of the circuit elements can be arranged in the handle assembly b. Furthermore, the handle assembly b is provided with a switch button a101 on the side facing the host housing a.

[0155] On the basis of the above embodiment, as a further limited embodiment, Figure 1 、 Figure 3 As shown, the handle assembly b is tilted. The tilted handle assembly b enables the user to maintain a tilted, more comfortable holding posture, thereby improving the user experience.

[0156] Specifically, such as Figure 3 As shown, X-X is the tilt axis of the handle in the tilt direction. Figure 3 From the perspective, the handle assembly b is tilted towards the air inlet assembly d3, and the extension direction of the air inlet assembly d3 is the location of the vacuum cleaner's suction head. Therefore, when cleaning with the handheld vacuum cleaner, the user can tilt it towards the area that needs to be cleaned, thereby improving the user experience. Figure 1 From the perspective, the end of the top of the handle component b connected to the lateral protrusion a104 is the first end b101 of the handle, and the end of the bottom of the handle component b connected to the power supply component f is the second end b102 of the handle. The first end b101 of the handle is located on the left side of the second end b102 of the handle.

[0157] Furthermore, the power supply assembly f is parallel to the lateral protrusion a104, and an indicator light f102 is provided on the side of the power supply assembly f facing the lateral protrusion a104.

[0158] On the basis of the above embodiment, as a further limited embodiment, Figure 6 As shown, the airflow generator includes: a vacuum motor c1; the handheld vacuum cleaner also includes: a motor base c3, the motor base c3 is assembled on the motor housing c2, and an assembly space for installing the vacuum motor c1 is formed between the motor base c3 and the motor housing c2.

[0159] On the basis of the above embodiment, as a further limited embodiment, Figure 7 、 Figure 8As shown, the handheld vacuum cleaner also includes a motor seal c4 disposed within the motor housing c2, sandwiched between the motor housing c2 and the vacuum motor c1. The vacuum motor c1 is secured to the upper and lower sides of the motor housing c2 and the motor base c3, respectively, with the motor seal c4 sandwiched between the vacuum motor c1 and the motor housing c2. The motor seal c4 fills the gap between the vacuum motor c1 and the motor housing c2, reducing the structural gap between the motor cover and the vacuum motor c1. When the vacuum motor c1 is operating, the motor seal c4 and the motor cover form a single unit. Furthermore, when the vacuum motor c1 vibrates, the motor seal c4, which is in close contact with the vacuum motor c1, is squeezed and deformed, reducing the vibration from propagating to the motor housing c2, thereby further reducing the noise generated by the vacuum motor c1 during operation. In the prior art, vacuum motor C1 generates noise primarily due to two factors: first, the vibration of the vacuum motor C1 itself during operation, which generates noise; second, the vibration of the vacuum motor C1 and other components connected to the vacuum motor C1, which further generates noise. This solution utilizes a motor seal C4 to prevent direct contact between the vacuum motor C1 and the motor housing C2, thereby eliminating the vibration generated by the vacuum motor C1 within the motor housing C2. This reduces the impact of the vibration generated by the vacuum motor C1 to the assembly space, significantly reducing the noise generated by the vacuum motor C1 during operation and resolving the noise problem of existing vacuum cleaners caused by the vibration of the vacuum motor C1.

[0160] Specifically, a ventilation area c403 is provided at the top of the motor seal c4 corresponding to the motor combing air outlet c201. The motor cover refers to the overall structure composed of the motor housing c2 and the motor base c3 for mounting the vacuum motor c1. The opening at the top of the motor cover is the motor combing air outlet c201, and a ventilation grille c2011 is provided on the motor combing air outlet c201. The ventilation grille c2011 can prevent users from putting their hands into the motor cover. Figure 2 - Figure 4 As shown, the motor cover outer shell is provided with a motor cover sealing ring c6. When the motor cover is assembled as a whole in the main body shell a, the motor cover sealing ring c6 is clamped between the inner wall of the main body shell a and the motor cover.

[0161] On the basis of the above embodiment, as a further limited embodiment, Figure 8As shown, the motor seal c4 comprises a base cushion layer c401, which is attached to the surface of the motor housing c2 facing the motor base c3; and a wrapping wall c402, which is provided on the base cushion layer c401 and extends toward the motor base c3. The wrapping wall c402 is sandwiched between the vacuum motor c1 and the inner wall of the motor housing c2. The wrapping wall c402 further fills the gap between the vacuum motor c1 and the inner wall of the motor housing c2, further reducing the impact of the vacuum motor c1's operating vibration on the outside world.

[0162] On the basis of the above embodiment, as a further limited embodiment, Figure 8 - Figure 11 As shown, the base shock absorber C5 is supported between the motor base C3 and the vacuum motor C1. The base shock absorber C5 sandwiched between the bottom of the vacuum motor C1 and the motor base C3 further weakens the transmission of vibrations from the vacuum motor C1 during operation, significantly reducing the overall impact of the vacuum motor C1 on the vacuum motor C1.

[0163] On the basis of the above embodiment, as a further limited embodiment, Figure 8 - Figure 11 As shown, the air guide cone c203 is provided with a conical foot c2033 at one end near the motor base c3. A foot support portion c302 extends from the motor base c3, and the foot support portion c302 is arranged directly opposite the conical foot c2033. Airflow enters through the lateral air outlet c2031 at the top of the air guide cone c203, then moves toward the bottom of the air guide cone c203 along the inner wall of the air guide cone c203, and finally enters the motor housing c2. During the flow, the airflow collides with the air guide cone c203, causing the air guide cone c203 to vibrate during operation. The motor base c3 supports the foot of the air guide cone c203, which can stabilize the air guide cone c203 and reduce its vibration.

[0164] On the basis of the above embodiment, as a further limited embodiment, Figure 8 - Figure 11 As shown, the base shock absorber c5 includes a foot shock absorber c503 extending between the conical foot c2033 and the foot support c302. The foot shock absorber c503 can eliminate the vibration of the air guide cone c203 by deforming itself, reducing the vibration of the air guide cone c203 from being transmitted to the base.

[0165] On the basis of the above embodiment, as a further limited embodiment, Figure 8 - Figure 11As shown, the support foot shock-absorbing portion c503 includes: at least two unit shock-absorbing pads c5031, which are stacked and sandwiched between the conical support foot c2033 and the support foot support portion c302. Multiple unit shock-absorbing pads c5031 can further improve the shock-absorbing performance of the support foot shock-absorbing portion c503.

[0166] On the basis of the above embodiment, as a further limited embodiment, Figure 8 - Figure 11 As shown, the support leg shock-absorbing portion c503 further includes a cushioning layer c5032 supported between adjacent unit shock-absorbing pads c5031. The cushioning layer c5032 can further improve the shock-absorbing performance of the support leg shock-absorbing portion c503. Furthermore, under the same stress conditions as the support leg shock-absorbing portion c503, the cushioning layer c5032 has a greater degree of elastic deformation. Therefore, when the cushioning layer c5032 is subjected to a vibration shock, the cushioning layer c5032 deforms itself, mitigating the deformation of the unit shock-absorbing pads c5031 and improving the shock-absorbing performance of the support leg shock-absorbing portion c503.

[0167] On the basis of the above embodiment, as a further limited embodiment, Figure 8 - Figure 11 As shown, a motor foot c101 is provided on a side of the vacuum motor c1 facing the motor base c3, and a foot matching portion c301 suitable for supporting the motor foot c101 is provided on the motor base c3.

[0168] On the basis of the above embodiment, as a further limited embodiment, Figure 8 - Figure 11 As shown, the base shock absorber c5 includes a foot shock absorber c502, one end of which is supported by the foot mating portion c301 and the other end of which has a slot suitable for inserting into the motor foot c101. The foot mating portion c301 in the motor base c3 is used to support and secure the vacuum motor c1. When the vacuum motor c1 vibrates during operation, the vibration is transmitted to the foot shock absorber c502, where it is reduced. This eliminates most of the vibration of the vacuum motor c1 during operation, significantly reducing the impact of the vibration of the vacuum motor c1 on the motor base c3 and confining the vibration of the vacuum motor c1 to the motor housing, thereby reducing the transmission of noise to the outside world.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
