[0013] As an optional feature of the vacuum cleaner, a baffle is provided on the side of the drain plate near the battery cell, and the baffle surrounds the circumference of the drain hole.

[0014] The enclosure provides for one or more of the drainage holes.

[0015] As an alternative to the vacuum cleaner, a gap is left between the battery cell and the inner wall of the housing, and the gap forms a heat dissipation channel.

[0037] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figures 1-3 As shown, this embodiment provides a vacuum cleaner, including a body, a fan assembly 2, a battery assembly 3, and a dust cup. The fan assembly 2 is used to drive airflow to generate negative pressure, so as to suck dust from the suction port of the dust cup into the dust cup. The battery assembly 3 is used to provide power to the fan assembly 2. Both the fan assembly 2 and the battery assembly 3 are located on the body. The body includes a handle 1 and a grip 11. The dust cup is located at one end of the handle 1, and the grip 11 is located at the other end of the handle 1. Both the fan assembly 2 and the battery assembly 3 are connected to the handle 1.

[0040] To improve suction performance and increase suction power, the fan assembly 2 has a higher power. After the fan assembly 2 has been working for a period of time, the battery assembly 3 will generate a lot of heat. Prolonged heating of the battery assembly 3 will affect its service life. At the same time, the hand handle 1 will feel noticeably hot to the touch due to the heat generated by the battery assembly 3.

[0041] To solve the above-mentioned technical problems, the vacuum cleaner provided in this embodiment includes a battery assembly 3 comprising a battery cell 31 and a housing 32. The battery cell 31 is disposed inside the housing 32. The housing 32 is provided with a heat dissipation inlet 3211 and a heat dissipation outlet that are interconnected. The heat dissipation inlet 3211 is connected to the air outlet 23 of the fan assembly 2 so as to use part of the airflow drawn into the machine body by the fan assembly 2 to dissipate heat from the battery assembly 3.

[0042] The fan assembly 2 and the battery assembly 3 are positioned opposite each other on both sides of the body. By positioning the fan assembly 2 and the battery assembly 3 opposite each other, the distance between the air outlet 23 of the fan assembly 2 and the heat dissipation inlet 3211 of the housing 32 is shortened, thereby shortening the flow path of the airflow after it flows out of the air outlet 23 and into the heat dissipation inlet 3211, reducing airflow loss and improving heat dissipation effect.

[0043] Specifically, the battery assembly 3 and the fan assembly 2 are positioned on opposite sides of the handle 1. A connecting plate 12 is provided at the end of the handle 1 away from the dust cup. The battery assembly 3 is positioned on one side of the connecting plate 12, and the outer periphery of the battery assembly 3 mounted on the connecting plate 12 is adapted to the outer periphery of the handle 1, so that the battery assembly 3 can be regarded as part of the handle 1. The fan assembly 2 is positioned on the other side of the connecting plate 12 and is adjacent to the grip handle 11. This does not affect the air intake of the fan assembly 2 or the air exhaust of the heat dissipation outlet of the housing 32. Moreover, the grip handle 11 provides some support for the fan assembly 2 and also increases the aesthetics of the vacuum cleaner.

[0044] The fan assembly 2 includes a motor 21 and a motor cover 22 covering the outer periphery of the motor 21. The motor cover 22 includes a circumferential wall surrounding the motor 21, and an air inlet 221 is provided on the circumferential wall. One side of the motor cover 22 is fixed to the handle 11, and the other side is set as an opening, which is the air inlet of the fan assembly 2. An air outlet 23 is provided at one end of the motor cover 22 facing the connecting plate 12. The axis of the air outlet 23 is parallel to the axis of the hand handle 1. The inside of the hand handle 1 is set as a hollow cavity, and the air outlet 23 communicates with the hollow cavity, so that the airflow from the air outlet 23 can flow through the hollow cavity of the hand handle 1 to the dust cup at the other end. At the same time, the connecting plate 12 is provided with a connecting port 121 connecting the air outlet 23 and the heat dissipation inlet 3211, so that part of the airflow from the air outlet 23 is introduced into the housing 32 through the connecting port 121.

[0045] like Figure 4 and Figure 5 As shown, a flow guide is also provided inside the housing 32. The flow guide is located circumferentially to the heat dissipation inlet 3211 to guide the airflow direction into the housing 32. The heat dissipation outlet is connected to the outside. The heat dissipation inlet 3211 on the housing 32 is connected to the air outlet 23 of the fan assembly 2, and part of the airflow from the air outlet 23 of the fan assembly 2 is introduced into the housing 32 to dissipate heat from the battery. By providing a flow guide inside the housing 32 and positioning it circumferentially to the heat dissipation inlet 3211 to guide the airflow direction into the housing 32, the airflow into the housing 32 is preferentially guided to the location with the most heat accumulation within the housing 32 for heat dissipation. This avoids the performance degradation of the battery assembly 3 or the overheating of a certain location on the handrail 1 due to excessively rapid temperature rise in a certain location within the housing 32, thereby improving the heat dissipation effect of the battery assembly 3 and reducing the risk of burns to the user.

[0046] In one embodiment, the flow guide includes a flow guide plate 33, which, together with the inner wall of the housing 32, forms a flow guide cavity 35. One side of the flow guide cavity 35 is connected to a heat dissipation inlet 3211, and the other side is provided with a flow guide hole 331. Multiple battery cells 31 are provided, and the flow guide holes 331 correspond to the battery cells 31. By setting the flow guide as a flow guide plate 33 and forming the flow guide cavity 35 with the inner wall of the housing 32, the airflow introduced into the housing 32 first converges within the flow guide cavity 35, preventing the airflow from dissipating after entering the housing 32 and affecting the heat dissipation effect. Then, the airflow flows out through the flow guide holes 331 to dissipate heat from the battery cells 31 at specific locations. It should be noted that the location of the flow guide hole 331 can be set according to the location of the battery cells 31 with the fastest temperature rise rate obtained from testing, to dissipate heat from the battery cells 31 at specific locations within the housing 32 or for a specific battery cell 31, thereby improving heat dissipation efficiency.

[0047] Specifically, such as Figures 5-8 As shown, the heat dissipation inlet 3211 on the housing 32 protrudes outward on the side wall. A flow guide plate 33 is then placed inside the protruding side wall and engaged with it to form a flow guide cavity 35. Engaging grooves 335 are provided on opposite sides of the flow guide plate 33. Correspondingly, an engaging protrusion 3213 is provided on the inner side of the protruding side wall. The engaging protrusion 3213 engages with the engaging grooves 335 to engage the flow guide plate 33 with the inner side of the protruding side wall.

[0048] Furthermore, in order to prevent the drainage plate 33 from expanding due to heat and deforming towards the side wall that is convex, thus affecting the volume of the drainage cavity 35, multiple support structures are distributed on the side of the drainage plate 33 near the side wall that is convex. These multiple support structures support the drainage plate 33, increase its strength, and prevent the drainage plate 33 from deforming due to heat and sticking to the side wall that is convex.

[0049] Multiple support structures include support plates 333 and support columns 334. The support plates 333 are located at the ends of the diversion plate 33, and the support columns 334 are spaced apart in the middle of the diversion plate 33. Furthermore, a support sleeve 3212 that mates with the support columns 334 is provided on the inner side of the outwardly protruding sidewall to ensure the support effect.

[0050] Of course, in other embodiments, the draining element can also be configured as a draining groove formed by the draining plate. The draining groove extends from the heat dissipation inlet 3211 to the battery cell 31 at a specific position. After the airflow enters through the heat dissipation inlet 3211, it flows along the draining groove to the battery cell 31 at the specific position to dissipate heat for the battery cell 31 at the specific position.

[0051] In one embodiment, multiple drainage holes 331 are provided, each corresponding to one battery cell 31; and the multiple drainage holes 331 are provided at different positions of the battery cell 31. By guiding airflow to one battery cell 31 through the multiple drainage holes 331, targeted heat dissipation is achieved at different positions of the battery cell 31, thereby achieving targeted heat dissipation at the higher temperature positions of the battery cell 31.

[0052] In one embodiment, multiple drainage holes 331 are provided, and the multiple drainage holes 331 correspond to at least two battery cells 31. For example, each battery cell 31 can be provided with one or more drainage holes 331. Such a configuration can dissipate heat for more than one specific battery cell 31, and can also provide targeted heat dissipation for two or three battery cells 31 with faster temperature rise rates.

[0053] In one embodiment, a baffle 332 is also provided on the side of the drain plate 33 near the cell 31, and the baffle 332 surrounds the circumference of the drain hole 331. The airflow flowing out of the drain cavity 35 through the drain hole 331 is intercepted by the baffle 332, so that the airflow blows directly to a specific position of the specific cell 31, avoiding the airflow dispersion from affecting the heat dissipation effect.

[0054] Furthermore, the enclosure 332 encloses one or more drainage holes 331. A enclosure 332 may enclose one drainage hole 331 or multiple drainage holes 331, depending on the size of the drainage hole 331 and the specific location of the battery cell 31, which will not be elaborated here.

[0055] In one embodiment, continue to refer to Figure 2 , Figure 4 and Figure 5 A gap is left between the battery cell 31 and the inner wall of the housing 32, forming a heat dissipation channel 36. Part of the airflow from the air outlet 23 of the fan assembly 2 enters the drainage cavity 35 through the heat dissipation inlet 3211, then dissipates heat on a specific battery cell 31 through the drainage hole 331, and then flows along the heat dissipation channel 36 to the heat dissipation outlet and is discharged to the outside.

[0056] In one embodiment, the housing 32 includes a bottom shell 321 and a top cover, which are fastened together to form a receiving cavity. The battery cell 31 is disposed in the receiving cavity. A heat dissipation inlet 3211 is disposed in the bottom shell 321, and a heat dissipation outlet is disposed in the top cover. After the bottom shell 321 and the top cover are fastened together, they are fixed by fastening screws. A snap-fit ​​member 34 is provided on the housing 32, and a bayonet 122 is provided on the connecting plate 12. The snap-fit ​​member 34 cooperates with the bayonet 122 to fix the battery assembly 3 to the connecting plate 12. Since the top cover is located outside the handheld lever 1, the heat dissipation outlet is located on the top cover, so that the airflow circulates inside the housing 32 and is discharged to the external environment through the heat dissipation outlet.

[0057] In one embodiment, the heat dissipation inlet 3211 is located in the middle of the bottom shell 321, and the heat dissipation outlet is located at one end of the top cover. The heat dissipation inlet 3211 is located near the battery cell 31 where the temperature rises faster, and the heat dissipation outlet is located at the end of the top cover, so that the airflow dissipates heat for a specific battery cell 31, then dissipates heat for other battery cells 31 along the heat dissipation channel 36 in the housing 32, and then exits through the heat dissipation outlet.

[0058] In one embodiment, such as Figure 9 and Figure 10 As shown, the top cover includes a cover body 322 and a decorative shell 323. The decorative shell 323 is snapped onto one end of the cover body 322, and a heat dissipation chamber 37 is formed between the cover body 322 and the decorative shell 323. The heat dissipation outlets include a first heat dissipation outlet 3221 and a second heat dissipation outlet 3231. The first heat dissipation outlet 3221 is located on the cover body 322, and the second heat dissipation outlet 3231 is located on the decorative shell 323. The second heat dissipation outlet 3231 and the first heat dissipation outlet 3221 are staggered, and the second heat dissipation outlet 3231 is located close to the bottom shell 321. The decorative shell 323 enhances the aesthetics of the vacuum cleaner. Furthermore, by placing the second heat dissipation outlet 3231, which communicates with the outside, close to the bottom shell 321, the exhausted hot air flows towards both sides of the handle 1, preventing the exhausted hot air from flowing towards the user's face and further reducing the risk of burns.

[0059] The heat dissipation inlet 3211, the first heat dissipation outlet 3221, and the second heat dissipation outlet 3231 are all configured with multiple strip holes, which are arranged in an array, either in one or two rows.

[0060] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
