Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a cleaning device. Background Technology

[0002] Smart homes are gaining increasing attention, and robotic vacuum cleaners are among the most widely accepted products in the process of automating household chores and freeing up people's hands. A robotic vacuum cleaner is an automated household cleaning device that can sweep and vacuum without human intervention and automatically avoid obstacles. As people's living standards improve, robotic vacuum cleaners need to have more advanced functions, such as purifying indoor air to provide users with a safe and fresh breathing environment. However, with these functions, the current carried by the machine will continuously increase, making heat dissipation between the related drive or power support modules a challenge. Under prolonged high-power operation, the power supply's battery cell temperature will rise, which will not only affect the power supply's output power but also reduce its lifespan. Furthermore, when the power supply battery cell temperature is too high, the battery may fail to charge, significantly impacting the user experience. Utility Model Content

[0003] Therefore, it is necessary to provide a cleaning device to address the problem that the temperature of the various modules driven or electrically supported by the robot vacuum cleaner with air purification function becomes too high after long-term high-power operation, affecting the operation of the device.

[0004] A cleaning device includes: a first body, the first body having a first mounting cavity, the first body having a first air inlet and a first air outlet respectively communicating with the first mounting cavity, the first body forming an air duct shell, the air duct shell having an air passage cavity; a battery, the battery being disposed in the air passage cavity, the battery being used to provide electrical energy for the cleaning device; a dust collection assembly, the dust collection assembly including a dust collection container and a first fan disposed in the first mounting cavity, the dust collection container having a dust collection cavity, the first fan having a suction port and an air outlet, the first air inlet, the dust collection cavity, the suction port, the air outlet, the air passage cavity and the first air outlet being sequentially connected, the first fan being configured to draw air through the suction port to create a negative pressure between the dust collection cavity and the first air inlet, and to input airflow into the air passage cavity through the air outlet to remove heat from the battery.

[0005] This application provides a cleaning device, including a first body, a battery, and a dust collection assembly. The dust collection assembly includes a dust collection container and a first fan disposed in a first mounting cavity of the first body. The first body also forms an air duct shell, and the battery is disposed in the air passage cavity of the air duct shell. The first fan is connected to both the dust collection container and the air duct shell. When the first fan is working, it draws air from the dust collection cavity of the dust collection container through the suction port to create a negative pressure at the dust collection cavity and the first air inlet. Under the action of the negative pressure, external dirt is drawn into the dust collection cavity from the first air inlet. At the same time, the airflow generated by the first fan enters from the air outlet, passes through the air passage cavity, and is discharged from the first air outlet. Thus, when the airflow flows through the battery in the air passage cavity, it can exchange heat with the battery and carry away heat, solving the problem of battery heat dissipation caused by the high-power operation of the cleaning device.

[0006] In one embodiment, a control circuit board is further included. The control circuit board is disposed in the first mounting cavity and is electrically connected to the first fan and the battery. The side wall of the air duct housing has an input port and a first output port, both communicating with the air passage cavity. The air outlet communicates with the air passage cavity through the input port, and the first output port communicates with the first mounting cavity and is positioned opposite to the control circuit board. The control circuit board contains high-performance chips, power devices, and wireless modules, which are heat-generating components. Excessive operating temperature can easily lead to circuit malfunctions or crashes, and prolonged operation can shorten its lifespan. By adopting the above structure, the control circuit board is positioned opposite the first output port. During the process of airflow from the air passage cavity entering the first mounting cavity through the first output port and then flowing to the air outlet for discharge, the airflow simultaneously blows towards the control circuit board, accelerating the airflow around the control circuit board. This allows the heat generated by the control circuit board to be dissipated more quickly, thus maintaining a more stable operating state.

[0007] In one embodiment, the outer peripheral wall of the battery and the inner peripheral wall of the air passage cavity cooperate to form an annular air duct. The inlet and the first outlet are both connected to the annular air duct and are located on opposite sides of the annular air duct. By adopting the above structure, as the airflow enters the annular air duct through the inlet and flows along the annular air duct to the first outlet, the airflow will fully and completely contact the outer peripheral wall of the battery, thereby improving the battery's heat dissipation effect.

[0008] In one embodiment, the control circuit board extends horizontally, and its sidewall is positioned opposite to the first output port. This arrangement allows the outer surface of the control circuit board to maximize contact with the airflow from the first output port, thus maximizing heat dissipation.

[0009] In one embodiment, the dust collection container, the first fan, the duct housing, and the control circuit board are arranged sequentially in a horizontal direction. This arrangement allows for compact installation of the components within the first unit, which helps to reduce the size of the cleaning device.

[0010] In one embodiment, the top and bottom walls of the first mounting cavity are each formed with a plurality of spaced-apart ribs, which abut against the outer wall of the battery. By employing this structure, the ribs on the top and bottom walls of the first mounting cavity can clamp the battery to provide a limiting effect, ensuring that the battery can be stably installed in a preset position to form an annular airflow channel. Furthermore, gaps can be formed between adjacent ribs to allow airflow, increasing the contact area between the battery and the air for better heat dissipation.

[0011] In one embodiment, the dust collection assembly further includes a first filter assembly disposed in the dust collection chamber. The first filter assembly is used to filter the airflow entering the suction port. When the cleaning device is started, outside air will carry dust and hair from the ground into the dust collection chamber through the first air inlet of the first body. Due to the first filter assembly, when the airflow flows through the first filter assembly to the suction port of the first fan, dust and hair can be adsorbed on the first filter assembly and accumulated in the dust collection chamber, thereby effectively preventing contamination of the first fan and the battery in the duct housing.

[0012] In one embodiment, the first housing includes a main body and a cover. The main body has a first mounting cavity, a first air inlet, and a first air outlet. The outer side of the bottom wall of the main body is recessed towards the first mounting cavity to form the air duct housing. The air duct housing has an air passage cavity with a bottom opening. The cover is detachably mounted on the air duct housing and is used to open or close the bottom opening. By adopting the above structure, the bottom opening of the air passage cavity can be opened and closed using the cover, which greatly facilitates the installation and removal of the battery.

[0013] In one embodiment, the first air outlet is located on the top wall of the first body, and the unit also includes an air purifier. The air purifier includes a second body, a second fan, and a second filter assembly. The second body is disposed on the top of the first body. The second body has a second mounting cavity and a second air inlet and a second air outlet communicating with the second mounting cavity. The second air inlet is disposed opposite to the first air outlet. The second fan and the second filter assembly are disposed in the second mounting cavity. The second fan is configured to drive the airflow output from the first air outlet into the second mounting cavity through the second air inlet and output to the outside through the second air outlet. The second filter assembly is used to filter the airflow entering the second mounting cavity. By adopting the above structure, the second fan draws air upward from the first air outlet, further accelerating the airflow speed within the first unit. This allows the heat from components such as the battery, control circuit board, and first fan to be expelled to the outside more quickly, improving heat dissipation. Furthermore, the airflow path is extended as it is discharged to the outside through the air purifier, which helps reduce airflow noise. Additionally, the airflow is further purified and filtered by the second filter assembly, which also reduces noise, greatly improving the device's quietness.

[0014] In one embodiment, the duct housing has a second outlet on the side facing the air purifier, and the air passage cavity is connected to the first air outlet or the second air inlet through the second outlet. The second outlet allows for a shorter airflow path between the air passage cavity and the second air inlet, making it easier for the airflow in the air passage cavity to be drawn in by the second fan, thus increasing the airflow velocity.

[0015] In one embodiment, the air duct housing includes a first housing and a second housing. The first housing is disposed on the first body and has the air passage cavity and the second outlet. One end of the second housing is connected to the first housing, and the other end of the second housing is connected to the bottom wall of the second body. The second housing has an air guide channel, and the second outlet communicates with the second air inlet through the air guide channel. By adopting the above structure, the second housing connects the first housing to the bottom of the second body, thereby allowing the second outlet to be directly connected to the second air inlet via the air guide channel. Utilizing the small flow area within the air guide channel, the airflow from the second outlet can maintain a high flow velocity towards the second air inlet, which is beneficial for the rapid dissipation of battery heat.

[0016] In one embodiment, the second fan is a centrifugal fan, the second air outlet is located on the peripheral wall of the second body, and the second filter assembly is annular, sleeved on the outside of the second fan and located between the air outlet of the second fan and the second air outlet. By adopting this structure, the airflow, under the action of the centrifugal fan, will pass evenly through the second filter assembly 360°, avoiding premature clogging of the second filter assembly due to excessively high local flow velocities.

[0017] In one embodiment, the second filtration assembly includes a pre-filter, a HEPA high-efficiency filter, and an activated carbon filter arranged sequentially. The pre-filter is located on one side near the air outlet of the second fan. The outermost pre-filter filters large particles of dust and hair, the middle HEPA high-efficiency filter filters out tiny bacteria, viruses, and PM2.5 pollutants, and the innermost activated carbon filter adsorbs harmful gases and odors such as formaldehyde and secondhand smoke.

[0018] In one embodiment, a cleaning component is also included, which is rotatably disposed at the bottom of the first body and is used to clean the surface to be cleaned.

[0019] In one embodiment, a walking assembly is also included, which is movably disposed at the bottom of the first body and is used to move the cleaning device on the surface to be cleaned. Attached Figure Description

[0033] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0035] The cleaning apparatus of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0036] like Figures 1 to 5As shown, this embodiment discloses a cleaning device, including: a first body 1, the first body 1 having a first mounting cavity 101, a first air inlet 102 and a first air outlet 103 respectively communicating with the first mounting cavity 101, the first body 1 forming an air duct housing 111, the air duct housing 111 having an air passage cavity 104; a battery 2, the battery 2 being disposed in the air passage cavity 104, the battery 2 being used to provide power to the cleaning device; and a dust collection assembly 3, the dust collection assembly 3 including a dust collector disposed in the first mounting cavity 101. The dust collection container 31 and the first fan 32 are provided. The dust collection container 31 is provided with a dust collection chamber 301. The first fan 32 is provided with a suction port 302 and an air outlet 303. The first air inlet 102, the dust collection chamber 301, the suction port 302, the air outlet 303, the air passage chamber 104 and the first air outlet 103 are connected in sequence. The first fan 32 is configured to draw air through the suction port 302 to form a negative pressure between the dust collection chamber 301 and the first air inlet 102, and to input airflow into the air passage chamber 104 through the air outlet 303 to remove the heat of the battery 2.

[0037] This application provides a cleaning device, including a first body 1, a battery 2, and a dust collection assembly 3. The dust collection assembly 3 includes a dust collection container 31 disposed in a first mounting cavity 101 of the first body 1 and a first fan 32. The first body 1 also forms an air duct housing 111, and the battery 2 is disposed in an air passage cavity 104 of the air duct housing 111. The first fan 32 is connected to both the dust collection container 31 and the air duct housing 111. When the first fan 32 is working, it draws air through a suction port 302. The air in the dust collection chamber 301 of the dust collection container 31 forms a negative pressure at the dust collection chamber 301 and the first air inlet 102. Under the action of negative pressure, external dirt is sucked into the dust collection chamber 301 from the first air inlet 102. At the same time, the airflow generated by the first fan 32 will be input from the air outlet 303, pass through the air chamber 104 and then be discharged from the first air outlet 103. Thus, when the airflow passes through the battery 2 in the air chamber 104, it can exchange heat with the battery 2 and carry away the heat, thus solving the problem of heat dissipation of the battery 2 caused by the high power operation of the cleaning device.

[0038] like Figure 2 , Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further includes a control circuit board 4, which is disposed in the first mounting cavity 101. The control circuit board 4 is electrically connected to the first fan 32 and the battery 2 respectively. The side wall of the air duct housing 111 is provided with an input port 105 and a first output port 106, both of which are connected to the air passage cavity 104. The air outlet 303 is connected to the air passage cavity 104 through the input port 105, and the first output port 106 is connected to the first mounting cavity 101 and is disposed opposite to the control circuit board 4. The control circuit board 4 has high-performance chips, power devices, and wireless modules, which are heat-generating components. If the operating temperature is too high, it is easy to cause circuit malfunction or crash, and long-term operation can easily shorten its lifespan. By adopting the above structure, the control circuit board 4 is positioned opposite to the first output port 106. As the airflow in the air cavity 104 enters the first mounting cavity 101 through the first output port 106 and then flows to the air outlet 303 for discharge, the airflow simultaneously blows onto the control circuit board 4 to accelerate the airflow around the control circuit board 4, so that the heat generated by the control circuit board 4 can be dissipated and discharged more quickly, so as to better maintain a stable working state.

[0039] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer peripheral wall of the battery 2 and the inner peripheral wall of the air passage 104 cooperate to form an annular air duct 107, and the inlet 105 and the first outlet 106 are both connected to the annular air duct 107 and are respectively located on opposite sides of the annular air duct 107. By adopting the above structure, as the airflow enters the annular air duct 107 through the inlet 105 and flows along the annular air duct 107 to the first outlet 106, the airflow will fully and completely contact the outer peripheral wall of the battery 2, thereby improving the heat dissipation effect of the battery 2.

[0040] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the control circuit board 4 extends in a horizontal direction, and the sidewall of the control circuit board 4 is disposed opposite to the first output port 106. By adopting the above arrangement, the outer surface of the control circuit board 4 can contact the airflow output from the first output port 106 to the greatest extent and carry away heat.

[0041] like Figure 2 , Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the dust collection container 31, the first fan 32, the air duct housing 111, and the control circuit board 4 are arranged sequentially in the horizontal direction. By adopting the above arrangement, the components inside the first body 1 can be compactly installed, which is beneficial to reducing the size of the cleaning device.

[0042] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the top and bottom walls of the first mounting cavity 101 are respectively formed with a plurality of spaced-apart ribs 11111, and the plurality of ribs 11111 abut against the outer wall of the battery 2. By adopting the above structure, the ribs 11111 on the top and bottom walls of the first mounting cavity 101 can cooperate to clamp the battery 2 to limit the battery 2, ensuring that the battery 2 can be stably installed in a preset position to form an annular air duct 107, and gaps can be formed between adjacent ribs 11111 to allow airflow, thereby increasing the contact area between the battery 2 and the air to achieve a better heat dissipation effect.

[0043] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the dust collection assembly 3 also includes a first filter assembly 33, which is disposed in the dust collection chamber 301 and is used to filter the airflow entering the suction port 302. When the cleaning device is started, the outside air will carry dust and hair on the ground into the dust collection chamber 301 through the first air inlet 102 of the first body 1. With the arrangement of the first filter assembly 33, when the airflow flows through the first filter assembly 33 to the suction port 302 of the first fan 32, the dust and hair can be adsorbed on the first filter assembly 33 and accumulated in the dust collection chamber 301, thereby effectively preventing the first fan 32 and the battery 2 in the air duct housing 111 from being contaminated.

[0044] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines: the first body 1 includes a body 11 and a cover 12. The body 11 is provided with a first mounting cavity 101, a first air inlet 102 and a first air outlet 103. The outer side of the bottom wall of the body 11 is recessed towards the first mounting cavity 101 to form a duct housing 111. The duct housing 111 is provided with a ventilation cavity 104 with a bottom opening. The cover 12 is detachably mounted on the duct housing 111 and is used to open or close the bottom opening. By adopting the above structure, the bottom opening of the ventilation cavity 104 can be opened and closed using the cover 12, thereby greatly facilitating the installation and removal of the battery 2.

[0045] like Figure 2As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first air outlet 103 is located on the top wall of the first body 1, and also includes an air purifier 5. The air purifier 5 includes a second body 51, a second fan 52, and a second filter assembly 53. The second body 51 is disposed on the top of the first body 1. The second body 51 is provided with a second mounting cavity 501 and a second air inlet 502 and a second air outlet 503 communicating with the second mounting cavity 501. The second air inlet 502 is disposed opposite to the first air outlet 103. The second fan 52 and the second filter assembly 53 are disposed in the second mounting cavity 501. The second fan 52 is configured to drive the airflow output from the first air outlet 103 into the second mounting cavity 501 through the second air inlet 502 and output to the outside through the second air outlet 503. The second filter assembly 53 is used to filter the airflow entering the second mounting cavity 501. By adopting the above structure, the second fan 52 draws air upward from the first air outlet 103, which further accelerates the airflow speed inside the first body 1. This allows the heat from components such as the battery 2, control circuit board 4, and first fan 32 in the first body 1 to be discharged to the outside more quickly, improving the heat dissipation effect. In addition, the airflow is discharged to the outside through the air purifier 5, which extends the airflow path and helps reduce airflow noise. Furthermore, the airflow is further purified and filtered by the second filter assembly 53, which also reduces noise, greatly improving the device's quietness performance.

[0046] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a second outlet 108 is provided on the side of the air duct housing 111 facing the air purifier 5, and the air passage cavity 104 is connected to the first air outlet 103 or the second air inlet 502 through the second outlet 108. The provision of the second outlet 108 allows for a shorter airflow path between the air passage cavity 104 and the second air inlet 502, thereby making it easier for the airflow in the air passage cavity 104 to be driven and drawn in by the second fan 52, increasing the airflow velocity.

[0047] like Figure 2 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the air duct housing 111 includes a first housing 1111 and a second housing 1112. The first housing 1111 is disposed on the first body 1, and the first housing 1111 has an air passage 104 and a second outlet 108. One end of the second housing 1112 is connected to the first housing 1111, and the other end of the second housing 1112 is connected to the bottom wall of the second body 51. The second housing 1112 has an air guide channel 109, and the second outlet 108 is connected to the second air inlet 502 through the air guide channel 109. By adopting the above structure, the second housing 1112 connects the first housing 1111 to the bottom of the second body 51, thereby the second outlet 108 is directly connected to the second air inlet 502 through the air guide channel 109. Utilizing the small flow area within the air guide channel 109, the airflow output from the second outlet 108 can maintain a high flow velocity towards the second air inlet 502, which is beneficial for the rapid dissipation of heat from the battery 2.

[0048] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second fan 52 is a centrifugal fan, the second air outlet 503 is located on the peripheral wall of the second body 51, and the second filter assembly 53 is annular, sleeved on the outside of the second fan 52, and located between the air outlet end of the second fan 52 and the second air outlet 503. By adopting the above structure, the airflow will pass through the second filter assembly 53 evenly in 360° under the action of the centrifugal fan, avoiding premature clogging of the second filter assembly 53 due to excessively high local flow velocity.

[0049] In addition to the features of the above embodiments, this embodiment further specifies that: the second filter assembly 53 includes a pre-filter, a HEPA high-efficiency filter, and an activated carbon filter arranged sequentially, with the pre-filter located on the side near the air outlet of the second fan 52. The outermost pre-filter is used to filter large particles of dust and hair, the middle HEPA high-efficiency filter can filter out tiny bacteria, viruses, and PM2.5 pollutants, and the innermost activated carbon filter is used to adsorb harmful gases and odors such as formaldehyde and secondhand smoke.

[0050] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further includes a cleaning component 6, which is rotatably disposed at the bottom of the first body 1, and is used to clean the surface to be cleaned.

[0051] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further includes a walking component 7, which is movably disposed at the bottom of the first body 1. The walking component 7 is used to drive the cleaning device to move on the surface to be cleaned.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
