Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0051] The present invention provides a floor-standing air conditioner indoor unit.

[0052] In the embodiments of the present invention, as Figures 1 to 5 , Figure 12 and Figure 13 shown, the floor-standing air conditioner indoor unit includes a main unit 100 and a sub-unit 200. The sub-unit 200 is detachably connected to the main unit 100 and can work independently relative to the main unit 100; the sub-unit 200 includes a housing 210, a first fan assembly 230, and an air outlet ring 231; the first fan assembly 230 is disposed in the housing 210, and the first fan assembly 230 is provided with a first air inlet 203; the air outlet ring 231 is provided with a first air outlet 204 disposed around the periphery of the air outlet ring 231.

[0053] The floor-standing air conditioner indoor unit is used to adjust the air in the room. An indoor heat exchange module may be provided in the main unit 100 for heat exchange adjustment of the indoor air, such as refrigeration, heating, etc. The specific structure of the heat exchange module of the main unit 100 can refer to the existing technology of the floor-standing air conditioner indoor unit and will not be elaborated here. The sub-unit 200 has an air outlet function to be able to blow and adjust the indoor air. The sub-unit 200 is detachably connected to the main unit 100, so that the adjustment of the indoor air by the sub-unit 200 and the adjustment of the indoor air by the main unit 100 can be interconnected and can also be independent of each other, so that the sub-unit 200 will not affect the heat exchange effect of the indoor heat exchange module when connecting to and disconnecting from the main unit 100, ensuring the heat exchange stability of the entire floor-standing air conditioner indoor unit.

[0054] It can be understood that the connection mode between the slave unit 200 and the master unit 100 can be determined according to the actual situation. The slave unit 200 can be connected inside the master unit 100 or outside the master unit 100. Optionally, the specific connection structure between the slave unit 200 and the master unit 100 can be snap connection, magnetic attraction connection, plug connection, etc. When the slave unit 200 is detached from the master unit 100, the slave unit 200 can move indoors relative to the master unit 100 to meet different indoor air conditioning requirements. For example, when the master unit 100 exchanges heat in a certain area of the room, the slave unit 200 can relay the air supply to other areas of the room, so that the air in other areas can also be quickly heated and cooled, increasing the range of air heat exchange and conditioning; when the master unit 100 is not turned on, the slave unit 200 can independently supply and adjust the air, playing an independent role in air conditioning; or when there is a crowded area indoors, it can realize long-distance, fixed-point, and directional air supply, improving the air treatment effect.

[0055] In this embodiment, the slave unit 200 includes a first fan assembly 230 and an air outlet ring 231 provided in the housing 210. The first fan assembly 230 is provided with a first air inlet 203, and the air outlet ring 231 is provided with a first air outlet 204, so that indoor air can enter the housing 210 from the first air inlet 203 and then be blown out from the first air outlet 204 to realize the function of supplying air indoors. It can be understood that the air outlet ring 231 has a central through hole 231a, and the first air outlet 204 is arranged around the periphery of the air outlet ring 231. When the first air outlet 204 blows air into the room, a negative pressure will be formed at the periphery of the air outlet ring 231 to drain the air located outside the first air outlet 204 and at the central through hole 231a into the air flow blown out from the first air outlet 204 and mix with the air flow to achieve the effect of increasing the air supply volume.

[0056] In the actual application process, the specific installation position of the air outlet ring 231 can be determined according to the actual situation. For example, it can be installed on the top or side of the casing 210, so that the air flow blown out from the first air outlet 204 can be blown sideways, or upwards, or obliquely upwards, etc., which can meet the blowing requirements at different heights or directions, and at the same time can also realize the relay blowing function for different areas in the room. For example, when the main unit 100 is fixedly installed in the living room and the air heat exchange effect of the main unit 100 in the living room cannot cover other areas such as the kitchen or bedroom, at this time, the slave unit 200 can be placed at the door of the kitchen or bedroom, and the first air outlet 204 of the air outlet ring 231 can be directed towards the kitchen or bedroom. Thus, through the guiding effect of the air outlet ring 231, the heat-exchanged air in the living room can be drained through the central through hole 231a of the air outlet ring 231 and the outer periphery of the air outlet ring 231 to be mixed with the air flow blown out from the first air outlet 204, and the mixed gas can be blown into the kitchen or bedroom to increase the air volume blown into the kitchen or bedroom and accelerate the air conditioning efficiency in the kitchen or bedroom. Or, the slave unit 200 can also be placed inside the kitchen or bedroom, and a negative pressure can be formed at the first air outlet 204 through the air outlet ring 231 to suck the heat-exchanged air in the living room into the kitchen or bedroom to adjust the air in the kitchen or bedroom. It should be noted that considering that the air outlet of the main unit 100 of the floor-standing air conditioner indoor unit is usually located at a relatively high position, and the air flow blown out by the main unit 100 is blown out from a relatively high position. Optionally, the air outlet ring 231 can be installed on the top or a position close to the top of the casing 210 of the slave unit 200 to achieve a better relay air supply effect and realize the air conditioning of more areas in the room.

[0057] Optionally, the air outlet ring 231 can be fixedly installed on the casing 210 or can be movably connected to the casing 210. When the air outlet ring 231 is fixedly installed on the casing 210, in order to increase the air outlet volume, the air outlet ring 231 can be externally installed on the casing 210 so that the central through hole 231a of the air outlet ring 231 can smoothly drain. When the air outlet ring 231 is movably connected to the casing 210, when the first air outlet 204 needs to blow air, the air outlet ring 231 can move to the outside of the casing 210 to realize the functions of smooth drainage and air supply; when the first air outlet 204 does not need to blow air, the air outlet ring 231 can move to be accommodated inside the casing 210 to achieve the integrity of the overall appearance of the machine and at the same time play a role in protecting the air outlet ring 231.

[0058] It can be understood that the air outlet ring 231 can be arc-shaped, rectangular, triangular or other irregular shapes, as long as it is ensured that the air outlet ring 231 has a central through hole for air flow diversion to pass through. The first air outlet 204 is arranged around the periphery of the air outlet ring 231. In fact, it can be a closed-loop air outlet form, an arc-shaped air outlet form, or a form in which a plurality of small holes are arranged and distributed on the periphery of the air outlet ring 231, etc., so that the air flow can be diverted from the central through hole 231a to the air outlet air flow to increase the air supply volume.

[0059] In the floor-standing air conditioner indoor unit of the technical solution of the present invention, by providing a slave unit 200 that can be detachably connected to the main unit 100, and the slave unit 200 has an air outlet function to achieve the effect of air conditioning for the whole or partial area of the room; the slave unit 200 includes a housing 210, a first fan assembly 230 and an air outlet ring 231. The first fan assembly 230 is provided with a first air inlet 203. The air outlet ring 231 is communicated with the first fan assembly 230. The air outlet ring 231 is provided with a first air outlet 204 arranged around the periphery of the air outlet ring 231, so as to divert the air located outside the first air outlet 204 and at the central through hole 231a of the air outlet ring 231 into the air outlet air flow blown out from the first air outlet 204 to achieve the effect of increasing the air supply volume.

[0060] In order to further increase the air supply range of the floor-standing air conditioner indoor unit, please refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 9 , the air outlet ring 231 is rotatably connected to the housing 210.

[0061] It can be understood that when the air outlet ring 231 rotates relative to the housing 210, it can drive the first air outlet 204 to rotate relative to the housing 210, thereby adjusting the air outlet direction of the first air outlet 204 to achieve the function of increasing the air supply range. In the actual application process, the rotation mode of the air outlet ring 231 and the housing 210 can be determined according to the actual situation. For example, it can be realized by a driving transmission mode such as a driving motor driving a gear combination, a sprocket combination or a worm and worm combination. The specific rotation direction of the air outlet ring 231 and the housing 210 is not limited. For example, it can be left-right rotation or up-down rotation, etc.

[0062] Optionally, the air outlet ring 231 is arranged at the top of the housing 210. In actual application, the location of the air outlet ring 231 can be determined according to actual conditions, such as being arranged at the top or side of the housing 210. In this embodiment, considering the air supply and drainage effect of the air outlet ring 231, the air outlet ring 231 is arranged at the top of the housing 210, so that the sub-unit 200 can supply air itself while also having a better relay air supply effect for the airflow blown out by the main unit 100. On the basis of the aforementioned embodiment, the air outlet ring 231 can rotate relative to the housing 210, so that the airflow of the sub-unit 200 and the airflow blown out by the main unit 100 can be guided to a wider area together, so as to achieve air conditioning in more areas of the room.

[0063] Furthermore, the air outlet ring 231 can rotate up and down relative to the housing 210. On the basis of the above-mentioned embodiment, the air outlet ring 231 is arranged at the top of the housing 210. It can be understood that when the air outlet ring 231 rotates up and down relative to the housing 210, it will drive the first air outlet 204 to rotate up and down, thereby enabling the air flow to be blown out within a range of different heights, thereby increasing the height range of the air flow. When the sub-machine 200 and the main machine 100 jointly operate the relay air supply, considering that the air outlets of most main machines 100 are set at a higher position, when the air outlet ring 231 rotates up and down, it can better guide the heat exchange air flow blown out by the main machine 100 to the area range of different heights to achieve different air conditioning effects.

[0064] Specifically, see Figure 2 , Figure 3 , Figure 5 as well as Figure 9 The first fan assembly 230 includes a first air duct shell 232 arranged on the top of the casing 210 and a first wind wheel 233 arranged in the first air duct shell 232, the air outlet ring 231 is rotatably connected to the first air duct shell 232, and the first air outlet 204 is connected to the first air duct shell 232.

[0065] It can be understood that the first wind wheel 233 plays a role in driving the airflow, so as to drive the indoor air into the first air duct shell 232 and blow it out from the first air outlet 204 of the air outlet circle 231. The first wind wheel 233 can be a centrifugal fan. The first air duct shell 232 can be accommodated in the interior of the housing 210, or it can be exposed to the housing 210. Its specific setting position can be determined according to actual conditions. In this embodiment, the first air duct shell 232 can be set in the interior of the housing 210 to reduce the overall structure of the sub-machine 200, while ensuring the integrity of the appearance of the sub-machine 200. It should be noted that the first air duct shell 232 can be a shell structure independent of the housing 210, or it can be a part of the housing 210, so as to accommodate the first wind wheel 233 to form a guiding effect on the airflow.

[0066] In actual application, the specific structural shape of the first air duct housing 232 can be determined according to the actual situation. Optionally, the first air duct housing 232 includes a volute 2321 and a tee 2322. One end of the tee 2322 is communicated with the volute 2321, and the other two ends are both communicated with the air outlet ring 231. The air outlet ring 231 is rotatably connected to the tee 2322. The first air wheel 233 is arranged in the volute 2321. A first air inlet 203 is provided on the volute 2321.

[0067] It can be understood that the tee 2322 functions to connect the volute 2321 and the air outlet ring 231. On the basis of the foregoing embodiment, the volute 2321 is arranged at the top of the housing 210, and the air outlet ring 231 can rotate up and down. By providing the tee 2322, the fixed volute 2321 can be connected to the movable air outlet ring 231 to achieve the function of smooth air guiding. In this embodiment, one end of the tee 2322 is communicated with the volute 2321, and the other two ends are communicated with the air outlet ring 231, so that the air flow in the volute 2321 can enter the air outlet ring 231 from both ends of the tee 2322 at the same time, reducing the air flow path in the air outlet ring 231, thereby reducing the air volume loss. At the same time, by entering from the two air passing openings of the air outlet ring 231, the air flow in the air outlet ring 231 is more uniform, reducing the noise caused by uneven air flow.

[0068] Optionally, a rotating mechanism can be provided at both ends where the air outlet ring 231 is connected to the tee 2322, so that the rotation of the air outlet ring 231 is more stable and reliable through the two opposite rotating mechanisms.

[0069] In this embodiment, the first air wheel 233 is arranged in the volute 2321. By driving the indoor air to enter the volute 2321 from the first air inlet 203, and then passing through the tee 2322 and the air outlet ring 231 in sequence, it is blown out from the first air outlet 204. Optionally, the first air inlet 203 is arranged at the top of the volute 2321.

[0070] Further, please refer to Figure 2 、 Figure 3 and Figure 11 , the housing 210 is provided with a receiving groove 211 for receiving the air outlet ring 231, and the receiving groove 231 is arranged around the outer periphery of the first air inlet 203.

[0071] It can be understood that the receiving groove 211 functions to receive the air outlet ring 231. When the first air outlet 204 does not need to blow air, the air outlet ring 231 can be received in the receiving groove 211. Optionally, the setting position of the receiving groove 211 can be determined according to the actual situation, such as it can be arranged at the top or side of the housing 210.

[0072] Based on the foregoing embodiments, the volute 2321 is provided at the top of the casing 210. To ensure the integrity of the overall appearance of the slave unit 200, the volute 2321 is accommodated inside the casing 210. In this embodiment, by providing the receiving groove 211 on the outer periphery of the volute 2321 and arranging it around the first air inlet 203, when the air outlet ring 231 is accommodated in the receiving groove 211, it surrounds the outer periphery of the volute 2321, making full use of the internal space at the top of the casing 210. When the first fan assembly 230 operates, the air outlet ring 231 rotates above the casing 210 to ensure that the central through hole 231a can pass through the air flow, realizing the function of guiding the air flow to increase the air volume; or when the first fan assembly 230 does not operate, the air outlet ring 231 can rotate to be accommodated in the receiving groove 211, which plays a role in protecting the air outlet ring 231 and at the same time reduces the overall height of the slave unit 200.

[0073] To achieve a better air guiding effect, please refer to Figure 3 、 Figures 8 to 11 , in an embodiment of the present invention, the first air outlet 204 is in a slit shape. It can be understood that compared with air outlets of other shapes, when the air volume of the air flow is certain, the air flow velocity blown out from the slit-shaped first air outlet 204 is greater, and thus it can better drive the surrounding air into the air outlet air flow, so as to achieve the effect of increasing the blowing air volume and the air supply distance. Optionally, the first air outlet 204 is arranged around the periphery of the central through hole 231a to achieve a larger air outlet area, and thus a wider air supply range.

[0074] Optionally, the aperture gap of the first air outlet 204 is not less than 1 mm and not greater than 4 mm. The aperture gap of the first air outlet 204 cannot be too large or too small. If it is too small, it is easy to increase the air resistance and reduce the air volume; if it is too large, the air guiding effect is poor. In this embodiment, the aperture gap of the first air outlet 204 can be selected as 1 mm, 2 mm, 3 mm or 4 mm.

[0075] Specifically, the air outlet ring 231 has a wind guiding wall 2311 away from the central axis. In the direction of the air outlet airflow, the wind guiding wall 2311 is inclined outward relative to the central axis of the air outlet ring 231. It can be understood that the wind guiding wall 2311 serves to guide the air outlet airflow outwards from the air outlet ring 231. In the direction of the air outlet airflow, the wind guiding wall 2311 is inclined outward relative to the central axis so that the air outlet airflow can diverge and blow out along the wind guiding wall 2311, thereby achieving the effect of expanding the range of the air outlet airflow. At the same time, considering that in the foregoing embodiment, the first air inlet 203 is provided at the top of the volute 2321 and the air outlet ring 231 is arranged around the outer periphery of the volute 2321, the wind guiding wall 2311 diverges and blows out the air outlet airflow to prevent the air outlet airflow from flowing back to the first air inlet 203.

[0076] Optionally, it is defined that the inclination angle of the wind guiding wall 2311 relative to the central axis of the air outlet ring 231 is between 0° and 45°. It can be understood that the inclination angle of the wind guiding wall 2311 relative to the central axis of the air outlet ring 231 cannot be too large, otherwise the wind guiding effect of the wind guiding wall 2311 is poor. Further, for a better wind guiding effect, the inclination angle of the wind guiding wall 2311 relative to the central axis of the air outlet ring 231 is between 0° and 20°, and can be optionally 1°, 5°, 10°, 15° or 20°, etc.

[0077] In an embodiment of the present invention, please refer to Figures 8 to 17 , the wind guiding wall 2311 includes a first wind guiding section 2311a and a second wind guiding section 2311b. The second wind guiding section 2311b is arranged on the side of the first wind guiding section 2311a close to the first air outlet 204; the first wind guiding section 2311a is parallel to the central axis of the air outlet ring 231, and the second wind guiding section 2311b is inclined outward relative to the first wind guiding section 2311a.

[0078] In this embodiment, in order to prevent air flow short - circuit, by setting the wind guiding wall 2311 as the first wind guiding section 2311a and the second wind guiding section 2311b, and the second wind guiding section 2311b is inclined outward relative to the first wind guiding section 2311a, so that the air flow can first flow along the first wind guiding section 2311a to the second wind guiding section 2311b, and then diverge and blow out from the second wind guiding section 2311b.

[0079] It can be understood that the first air inlet 203 is provided at the top of the volute 2321, and the air outlet ring 231 is arranged around the outer periphery of the volute 2321. Then, the first air outlet 204 is also arranged around the periphery of the first air inlet 203, resulting in a relatively short distance between the first air outlet 204 and the first air inlet 203. The air flow blown out from the first air outlet 204 is easily sucked into the first air inlet 203 or has a tendency to flow towards the first air inlet 203, which affects the drainage effect of the hollow area of the air outlet ring 231 and even causes the phenomenon of air flow short - circuit. To prevent this phenomenon from occurring, the second air guiding section 2311b on the side close to the first air outlet 204 is inclined outward, so that the air flow can flow along the outward - inclined second air guiding section 2311b and be blown out from the first air outlet 204 in a direction away from the first air inlet 203, thereby reducing the impact on the drainage effect and also preventing the air flow from flowing back to the first air inlet 204. For specific reference, Figure 14 and Figure 15 the comparison with Figure 16 and Figure 17 the comparison shows that when the second air guiding section 2311b is inclined outward, the air flow rate of the air flow blown out from the first air outlet 204 flowing back to the first air inlet 204 is reduced, achieving a better air outlet drainage effect.

[0080] It should be noted that the outward - inclined angle α of the second air guiding section 2311b cannot be too large. Since the air flow flows from the first air guiding section 2311a to the second air guiding section 2311b, there is still a tendency for the air flow to flow along the first air guiding section 2311a when it reaches the connection between the two. When the outward - inclined angle α of the second air guiding section 2311b is too large, it is easy to cause more air flow not to flow along the second air guiding section 2311b but to directly separate from the second air guiding section 2311b, and it will not achieve the effect of outward - divergent blowing. Optionally, the outward - inclined angle α of the second air guiding section 2311b relative to the first air guiding section 2311a is between 0° and 45°. In actual application, the outward - inclined angle α of the second air guiding section 2311b can be 1°, 5°, 10°, 15° or 20°, etc.

[0081] Furthermore, please refer to Figures 8 to 17 , to ensure the air guiding effect of the air guiding wall 2311 and prevent the air flow from flowing back into the first air inlet 203, define the depth of the first air guiding section 2311a as L1 and the depth of the second air guiding section 2311b as L2, satisfying: L2 / (L1 + L2)≥30%, that is, the second air guiding section 2311b cannot be too short. If it is too short, it will not achieve the effect of outward - divergent air guiding for the air flow blown out.

[0082] It can be understood that, on the basis of the foregoing embodiments, since the distance between the first air outlet 204 and the first air inlet 203 is relatively close, the air flow blown out from the first air outlet 204 is easily sucked into the first air inlet 203 or has a tendency to flow towards the first air inlet 203, which affects the drainage effect of the hollow area of the air outlet ring 231 or even causes the phenomenon of air flow short - circuit. To prevent this phenomenon from occurring, the second air guiding section 2311b on the side close to the first air outlet 204 is arranged to be inclined outwards. In this embodiment, in order to achieve a better effect of preventing air flow short - circuit, the depth L2 of the second air guiding section 2311b has certain requirements. In the actual application process, air flow flows from one end of the second air guiding section 2311b connected to the first air guiding section 2311a to the air outlet end of the second air guiding section 2311b and is blown out from the first air outlet 204. When the depth L2 of the second air guiding section 2311b is too short, the distance between the air outlet end of the second air guiding section 2311b and the first air guiding section 2311a is relatively close, resulting in the distance between the air outlet end of the second air guiding section 2311b and the first air inlet 203 being relatively close, and still easily causing the air flow flowing out from the air outlet end of the second air guiding section 2311b to be adsorbed by the first air inlet 203 or directly sucked in. Therefore, the depth L2 of the second air guiding section 2311b cannot be too short, and it can satisfy L2 / (L1 + L2)≥30%, so as to increase the distance between the air outlet end of the second air guiding section 2311b and the first air inlet 203, thereby achieving a better effect of diverging the air flow outwards and further achieving a better effect of preventing air flow short - circuit.

[0083] In an embodiment of the present invention, please refer to Figure 2 、 Figures 4 to 7 , the slave unit 200 further includes a second fan assembly 220 disposed in the housing 210. The housing 210 is provided with a second air inlet 201 and a second air outlet 202; the second fan assembly 220 includes a second air duct housing 221 formed in the housing 210 and a second impeller 222 disposed in the second air duct housing 221. Both the second air inlet 201 and the second air outlet 202 are communicated with the second air duct housing 221. In this embodiment, the second impeller 222 drives indoor air to enter the second air duct housing 221 from the second air inlet 201 and is blown out from the second air outlet 202 to realize the function of supplying air indoors. In the actual application process, the second impeller 222 can adopt a centrifugal fan, an axial - flow fan or a contra - rotating fan, etc. In this embodiment, the second impeller 222 is selected as a double - centrifugal fan. By the operation of the double - centrifugal fan, the air flow volume is increased; optionally, the second air inlet 201 is disposed on opposite sides of the housing 210, which can be understood as being arranged corresponding to the two air inlet sides of the double - centrifugal fan. In order to further increase the air outlet volume, the second air outlet 202 is disposed on the periphery of the housing 210 so as to be able to supply air to the periphery of the housing 210.

[0084] This embodiment realizes the function that the slave unit 200 can blow air through the first air outlet 204 and / or the second air outlet 202. Furthermore, it can blow air through different air outlets, that is, it can blow air only from the first air outlet 204, or only from the second air outlet 202, or blow air from both the first air outlet 204 and the second air outlet 202 simultaneously, so as to achieve different air outlet effects of the slave unit 200.

[0085] It can be understood that the second fan assembly 220 and the first fan assembly 230 are independent of each other. At this time, the user can operate the second fan assembly 220 and / or the first fan assembly 230 according to actual needs to realize blowing air from the first air outlet 204 and / or the second air outlet 202, thereby achieving various different air outlet effects.

[0086] In order to increase the air conditioning function of the slave unit 200 for indoor air, an air conditioning module is provided in the housing 210; the air conditioning module includes a purification module 240, a humidification module, a dehumidification module or an aromatization module to realize the functions of purifying, humidifying, dehumidifying or aromatizing indoor air.

[0087] In this embodiment, a purification module 240 is provided in the slave unit 200, and the purification module 240 is arranged at the second air inlet 201 to realize the purification effect on the incoming air flow. In the actual application process, combined with the air outlet ring 231 being arranged at the top of the housing 210 in the foregoing embodiment, it can be understood that the slave unit 200 can realize the purification function through components such as the second fan assembly 220 and the purification module 240 located in the housing 210, and at the same time, can realize the function of air supply and diversion through the first fan assembly 230 and the air outlet ring 231 located at the top of the housing 210, achieving the effect of both purifying and diverting to increase the air volume.

[0088] In an embodiment of the present invention, referring to Figure 12 and Figure 13 , the main unit 100 has a receiving cavity 110 for accommodating the slave unit 200, and the slave unit 200 can be accommodated in the receiving cavity 110 or separated from the receiving cavity 110. In this embodiment, the receiving cavity 110 can be located in the upper, middle or lower part of the main unit 100. Generally, the shape of the receiving cavity 110 is adapted to the shape of the slave unit 200, that is, in the non-working state, the slave unit 200 is completely accommodated in the receiving cavity 110. Of course, it is also possible that part of the slave unit 200 is located inside the receiving cavity 110 and part is located outside the receiving cavity 110, that is, part is exposed outside the main unit 100. By arranging at least part of the slave unit 200 in the receiving cavity 110 of the main unit 100, compared with the overall splicing of the slave unit 200 and the main unit 100, it is easier to maintain the overall consistency after the two are connected, thereby improving the user experience.

[0089] In an embodiment of the present invention, referring to Figure 12 andFigure 13 The slave unit 200 further includes a moving component 250 disposed at the bottom of the housing 210. The moving component 250 can drive the slave unit 200 to move relative to the master unit 100. Optionally, the moving component 250 can be in the form of a driving wheel plus a universal wheel, a roller plus a turntable, etc., so as to be able to drive the slave unit 200 to move and turn, thereby realizing multi-directional movement throughout the room.
