Currently, the water tank is usually arranged inside the body, and its size is limited by the body, resulting in a small volume and easy to be full of water. Users need to pour water relatively frequently, which affects the user experience. Summary of the Invention

[0003] The main object of the present invention is to propose a dehumidifier, aiming to increase the volume of the water tank to reduce the number of times of pouring water when the water tank is full.

[0004] To achieve the above object, the dehumidifier proposed by the present invention includes:

[0005] A body;

[0006] A water tank having an upward installation opening;

[0007] A support member that can move in and out of the installation opening, and has a first state of entering the installation opening and a second state of exiting the installation opening. In the first state, the support member can support the lower end of the body. In the second state, the body can be at least partially received in the water tank through the installation opening; the support member is provided with a limiting portion; and,

[0008] A limiting member that can be movably arranged in the water tank and has a first position and a second position. In the first position, the limiting member can cooperate with the limiting portion of the support member in the first state to limit the support member in the first state. In the second position, the limiting member is spaced apart from the limiting portion.

[0009] Optionally, the limiting member includes a floating portion arranged in the water tank and a limiting rod extending upward from the floating portion, and the limiting portion is a limiting hole arranged on the support member;

[0010] The floating portion floats upward under the action of the water in the water tank to drive the limiting rod to move upward until the limiting rod is inserted and matched with the limiting hole.

[0011] Optionally, the floating portion has a cavity; and / or, the material of the floating portion is foamed plastic.

[0012] Optionally, the floating portion has a sealed cavity, and the cavity is filled with air, nitrogen or helium.

[0013] Optionally, the water tank is provided with a mounting bracket which is installed on the inner side wall of the water tank. The mounting bracket is provided with a limiting groove which extends in the up-and-down direction, and the floating part is slidably installed in the limiting groove.

[0014] Optionally, the limiting member is arranged between the mounting bracket and the inner side wall of the water tank, and a water inlet hole is provided at the bottom of the mounting bracket.

[0015] Optionally, an avoidance groove is provided on the inner side wall of the water tank, and both the limiting member and the mounting bracket are arranged in the avoidance groove.

[0016] Optionally, an isolation rib is provided at the bottom of the mounting bracket. At the second position, the floating part abuts against the upper side of the isolation rib.

[0017] Optionally, the mounting bracket is detachably connected to the water tank.

[0022] Optionally, the support member is pivotally connected to the water tank. In the first state, the support member is pivoted to the horizontal state, and in the second state, the support member is pivoted to the vertical state.

[0023] In the technical solution of the present invention, the water tank is arranged outside the fuselage, and the volume of the water tank is increased to be able to accommodate at least part of the fuselage.

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.

[0043] The present invention provides a dehumidifier.

[0044] In an embodiment of the present invention, with reference to Figures 1 to 6 , the dehumidifier includes a body 200, a water tank 100, and a support member 300. The water tank 100 has an upward installation opening 110. The support member 300 can move in and out of the installation opening 110, and has a first state of entering the installation opening 110 and a second state of exiting the installation opening 110. In the first state, the support member 300 can support the lower end of the body 200. In the second state, at least part of the body 200 can be received in the water tank 100 through the installation opening 110.

[0045] It can be understood that in this embodiment, the support member 300 is spaced from the bottom wall of the water tank 100. The water tank 100 is arranged outside the body 200. When the body 200 is in the working state, the body 200 extends relative to the water tank 100, and the support member 300 moves into the installation opening 110 to be in the first state. At this time, the lower end of the body 200 can abut against the support member 300, so that the lower end of the body 200 is spaced from the bottom wall of the water tank 100, so that the water generated during the dehumidification work of the dehumidification device in the body 200 can be discharged into the water tank 100. When the dehumidification device in the body 200 finishes the dehumidification work and discharges or pours out the water in the water tank 100, the support member 300 is withdrawn from the installation opening 110 to be in the second state, so that at least part of the body 200 can be received in the water tank 100 through the installation opening 110, so that the body 200 is in the idle state.

[0046] During the use of the dehumidifier, for example, after the body 200 has been working for a period of time and there is already a certain amount of water in the water tank 100, there may be a situation where the user or others lift the body 200 and then place the body 200 on the water tank 100 to continue working. However, after the body 200 is lifted from the water tank 100, the support member 300 may automatically switch from the first state to the second state, or be manually operated to switch from the first state to the second state. At this time, if the body 200 is directly placed on the water tank 100 to continue working, the body 200 will directly fall into the water in the water tank 100, which is likely to cause water ingress and damage to the body 200.

[0047] Therefore, in this embodiment, the dehumidifier further includes a limiting member 400, and the support member 300 is provided with a limiting portion. The limiting member 400 is movably arranged on the water tank 100 and has a first position (reference Figure 8 ) and a second position (reference Figure 9) At the first position, the limiting member 400 can cooperate with the limiting portion of the support member 300 in the first state to limit the support member 300 in the first state. At the second position, the limiting member 400 is arranged at an interval from the limiting portion. That is, when the support member 300 is in the first state, the limiting member 400 is also moved to the first position to cooperate with the limiting portion of the support member 300. Thus, after the fuselage 200 is lifted from the water tank 100, the limiting member 400 can limit the support member 300 from switching from the first state to the second state, so as to ensure that when the fuselage 200 is placed back into the water tank 100 to continue working, the support member 300 can also support the fuselage 200 to prevent the fuselage 200 from falling into the water in the water tank 100. When the dehumidification work of the fuselage 200 is completed and the water in the water tank 100 is drained or poured out, the limiting member 400 is moved from the first position to the second position away from the limiting portion, so that the support member 300 can be withdrawn from the installation opening 110 and be in the second state, and thus at least part of the fuselage 200 can be received in the water tank 100 through the installation opening 110.

[0048] In the technical solution of the present invention, by arranging the water tank 100 outside the fuselage 200 and increasing the volume of the water tank 100 to be able to receive at least part of the fuselage 200, compared with a dehumidifier with the water tank 100 arranged inside the fuselage 200, the volume of the water tank 100 is increased in this way, so that the water tank 100 can receive more dehumidified water, thereby reducing the number of times of pouring water when the water tank 100 is full and improving the user experience. In addition, by providing a support member 300 that can move in and out of the installation opening 110, and a limiting member 400 that can be movably installed in the water tank 100 and can limit the support member 300 in the first state, the possibility that the support member 300 switches from the first state to the second state after the user or others lift the fuselage 200 can be reduced, so that the situation that the fuselage 200 falls into the dehumidified water in the water tank 100 and is damaged when the user or others place the fuselage 200 back into the water tank 100 to continue working can be effectively reduced.

[0049] Moreover, compared with the method of arranging a fixed support protrusion in the installation opening 110, there is no need to provide a concave structure on the outer side of the fuselage 200 to avoid the support protrusion. It can be understood that the concave structure will not only make the outer shell of the fuselage 200 more complex, affecting its manufacturing efficiency, but also occupy the space inside the fuselage 200. Furthermore, when the fuselage 200 is in the idle state, at least part of the fuselage 200 can be received in the water tank 100 through the installation opening 110 of the water tank 100, which can reduce the center of gravity of the dehumidifier, make the placement of the dehumidifier more stable and not prone to tipping over, and also reduce the overall occupied space of the dehumidifier, facilitating the user to place the dehumidifier; when the fuselage 200 is in the working state, the fuselage 200 extends out relative to the water tank 100, which can make the air outlet on the fuselage 200 have a higher position, so that the dehumidified air can be discharged to a higher position, and then the dehumidified air can be diffused into the entire indoor space faster.

[0050] In this embodiment, a plurality of support members 300 are provided at intervals along the circumference of the mounting opening 110 to provide more stable support for the fuselage 200. Taking the square mounting opening 110 and the fuselage 200 as an example, usually two support members 300 are provided, and the two support members 300 are respectively arranged on opposite sides of the mounting opening 110. Of course, both the fuselage 200 and the water tank 100 are square, but this is only an example shape of the fuselage 200 and the water tank 100. In other embodiments, the fuselage 200 and the water tank 100 can also be, but are not limited to, circular, polygonal, or even irregular shapes, as long as the shape of the mounting opening 110 is adapted to the cross-sectional shape of the fuselage 200. In addition, the number of the support members 300 can also be three or four.

[0051] Further, in one embodiment, the support member 300 is pivotally connected to the water tank 100. In the first state, the support member 300 is pivoted to a horizontal state, and in the second state, the support member 300 is pivoted to a vertical state. It should be noted that in this embodiment, the "vertical state" should be understood in a broad sense, that is, it does not only include the state where the support member 300 extends strictly vertically, but also includes the state where the support member 300 extends along a direction slightly inclined to the up and down direction; similarly, the "horizontal state" should also be understood in a broad sense, that is, it does not only include the state where the support member 300 extends strictly horizontally, but also includes the state where the support member 300 extends along a direction slightly inclined to the horizontal direction.

[0052] That is, in the first state, the support member 300 is pivoted to a horizontal state to enter the mounting opening 110, so as to provide support for the fuselage 200. In the second state, the support member 300 is pivoted to a vertical state to exit the mounting opening 110, so as to provide clearance for the fuselage 200 to be received into the water tank 100. Optionally, the support member 300 is plate-shaped, and the plate-shaped structure is simple and easy to be prepared in batches. In addition, in other implementations, the support member 300 can also be slidably connected to the water tank 100. Of course, its sliding direction is horizontal (horizontal direction or substantially horizontal direction) to slide in and out of the mounting opening 110 translationally.

[0053] Please refer to Figures 6 to 8, In one embodiment, the limiting member 400 includes a floating portion 410 disposed in the water tank 100 and a limiting rod 420 extending upward from the floating portion 410. The limiting portion is a limiting hole 310 provided in the support member 300. The floating portion 410 floats upward under the action of the water in the water tank 100 to drive the limiting rod 420 to move upward until the limiting rod 420 is inserted into and engaged with the limiting hole 310. Specifically, in the first state of the support member 300, the limiting hole 310 extends in the up-down direction. When there is water in the water tank 100, the buoyancy generated by the floating portion 410 in the water is greater than the gravity of the floating portion 410 and the limiting rod 420. Thus, the floating portion 410 can float upward under the action of the water, driving the limiting rod 420 to move upward and insert into the limiting hole 310, and it can ensure that the limiting rod 420 always has a tendency to move upward. At this time, if the support member 300 is to be switched from the first state to the second state, the hole wall of the limiting hole 310 will abut against the limiting rod 420, thereby preventing the support member 300 from being switched to the second state. After the water in the water tank 100 is drained or poured out, the floating portion 410 can move downward under its own gravity (i.e., move toward the bottom wall of the water tank 100), driving the limiting rod 420 to move downward and disengage from the limiting hole 310. At this time, the support member 300 can be switched from the first state to the second state. In this way, when there is water in the water tank 100, the buoyancy generated by the floating portion 410 in the water can ensure the insertion and engagement of the limiting rod 420 with the limiting hole 310 to limit the support member 300 in the first state. In this process, it is equivalent to the limiting member 400 automatically limiting the support member 300 in the first state when there is water in the water tank 100, without the user manually operating the limiting member 400, and it can also avoid the situation where the user accidentally operates and moves the limiting member 400 to the second position. In one embodiment, the end of the limiting hole 310 facing the bottom wall of the water tank 100 is flared, that is, the limiting rod 420 is inserted from the end of the limiting hole 310 facing the bottom wall of the water tank 100. Such a setting facilitates the insertion of the limiting rod 420. Of course, in other embodiments, the limiting member 400 can also be a pin or a screw, and the user manually operates the pin or the screw to cooperate with the limiting portion of the support member 300.

[0054] Among them, the structure of the floating part 410 has various forms. For example, in one embodiment, the floating part 410 has a cavity, which can reduce the weight of the floating part 410. Or when the weight of the floating part 410 is the same, it can increase the volume of the floating part 410, thereby increasing the contact area between the floating part 410 and water, so that the buoyancy generated by the floating part 410 in water is larger, ensuring that the floating part 410 can easily float. Among them, the floating part 410 can be formed by plastic blow molding or by bonding multiple plates. In one embodiment, the cavity of the floating part 410 is hermetically sealed, and the cavity is filled with air, nitrogen or helium. By hermetically sealing the cavity, it can prevent water from flowing into the cavity and ensure that the floating part 410 has a good floating effect. Moreover, since the relative molecular masses of nitrogen and helium are less than that of air, filling nitrogen or helium in the cavity is beneficial to improving the floating effect of the floating part 410. Of course, in other embodiments, an opening communicating with the cavity can also be provided at the upper end of the floating part 410 or on the limiting rod 420.

[0055] In one embodiment, the material of the floating part 410 is foamed plastic. This can also reduce the weight of the floating part 410. Or when the weight of the floating part 410 is the same, it can increase the volume of the floating part 410, thereby increasing the contact area between the floating part 410 and water, so that the buoyancy generated by the floating part 410 in water is larger, ensuring that the floating part 410 can easily float.

[0056] To improve the limiting effect of the limiting member 400 and the supporting member 300, in one embodiment, the limiting member 400 includes a plurality of limiting rods 420, and the plurality of limiting rods 420 are all arranged on the floating part 410. The supporting member 300 is provided with a plurality of limiting holes 310. One limiting rod 420 can be inserted and matched with one limiting hole 310 correspondingly. In this way, the limiting member 400 can limit multiple positions of the supporting member 300 through the plurality of limiting rods 420, increasing the contact area between the limiting member 400 and the supporting member 300, thereby improving the limiting effect of the limiting member 400. In one embodiment, the limiting member 400 further includes a connecting portion 430. The connecting rod connects any two adjacent limiting rods 420, that is, any two adjacent limiting rods 420 can be connected through the connecting portion 430 to improve the structural strength and stability of the limiting rod 420. The number of the connecting portions 430 can be one or more. For example, two limiting rods 420 can be connected through one, two or three connecting portions 430. Of course, in other embodiments, only one limiting rod 420 can also be provided. In addition, when a plurality of limiting rods 420 are provided, the connecting portion 430 can also not be provided.

[0057] Please refer to Figures 8 to 11In one embodiment, the water tank 100 is provided with a mounting bracket 500, which is mounted on the inner side wall of the water tank 100. The mounting bracket 500 is provided with a limiting groove 510, which extends in the up-down direction, and the floating part 410 is slidably mounted in the limiting groove 510. Specifically, the floating part 410 can move in the up-down direction in the limiting groove 510, and the mounting bracket 500 can limit the floating part 410 to move in the lateral direction (direction perpendicular to the up-down direction), which is equivalent to installing the limiting member 400 on the inner side wall of the water tank 100 through the mounting bracket 500. This ensures that the floating part 410 can move up and down, and can effectively limit the floating part 410, thereby ensuring the movement reliability of the limiting member 400. Of course, in other embodiments, the limiting rod 420 can also be slidably mounted in the limiting groove 510. Alternatively, a sliding groove can be provided on the inner side wall of the water tank 100, and the floating part 410 can be slidably mounted in the sliding groove.

[0058] In addition, other limiting structures may be provided on the mounting bracket 500. For example, in one embodiment, the mounting bracket 500 is further provided with a guide groove 520, which extends in the up-down direction, and the limiting rod 420 is slidably installed in the guide groove 520 to ensure the stability of the limiting rod 420 when it moves in the up-down direction. The guide groove 520 may be provided in the limiting groove 510, that is, the floating portion 410 and the limiting rod 420 are both located in the limiting groove 510, or the guide groove 520 may be provided outside the limiting groove 510. Of course, in other embodiments, the guide groove 520 may not be provided.

[0059] In one embodiment, the mounting bracket 500 includes a mounting portion 570 and a supporting portion 580, the limiting groove 510 is provided on the mounting portion 570, the supporting portion 580 is provided on the upper end of the mounting portion 570, and the supporting portion 580 has a clearance hole 581 for the limiting rod 420 to pass through. In the first state, the supporting portion 580 can be supported on the supporting member 300, that is, the supporting member 300 can be abutted against the upper end of the supporting portion 580, which is equivalent to being able to support the supporting member 300 through the mounting bracket 500, which is conducive to improving the load-bearing capacity of the supporting member 300.

[0060] In order to reduce the limiting structure of the mounting bracket 500 and simplify the installation process, in one embodiment, the limiting member 400 is disposed between the mounting bracket 500 and the inner side wall of the water tank 100, and a water inlet hole 530 is provided at the bottom of the mounting bracket 500. Specifically, the mounting bracket 500 is in a plate shape, and a limiting groove 510 is provided on the surface of the mounting bracket 500 facing the inner side wall of the water tank 100, that is, when the mounting bracket 500 is installed on the inner side wall of the water tank 100, the side of the mounting bracket 500 provided with the limiting groove 510 faces the inner side wall of the water tank 100. Thus, after the limiting member 400 is installed in the limiting groove 510, the mounting bracket 500 and the limiting member 400 can be installed on the inner side wall of the water tank 100 together, which is equivalent to jointly limiting the limiting member 400 by the inner side wall of the water tank 100 and the mounting bracket 500. In this way, the limiting structure on the mounting bracket 500 can be reduced, which is beneficial to simplifying the structure of the mounting bracket 500. Moreover, when the limiting member 400 is installed on the mounting bracket 500, the limiting member 400 can be simply placed in the limiting groove 510, and there is no need to perform excessive assembly on the limiting member 400, so that the installation process can be simplified. The bottom of the mounting bracket 500 is close to or abuts against the bottom wall of the water tank 100, and the floating portion 410 is located at the bottom of the mounting bracket 500. By providing the water inlet hole 530 at the bottom of the mounting bracket 500, it is ensured that the water in the water tank 100 can flow into the space between the inner side wall of the water tank 100 and the mounting bracket 500, so as to act on the floating portion 410. Of course, in other embodiments, the limiting member 400 can also be disposed on the side of the mounting bracket 500 facing away from the inner side wall of the water tank 100. In addition, the mounting bracket 500 may not be in a plate shape. For example, the mounting bracket 500 is a frame structure formed by connecting a plurality of cross bars and a plurality of vertical bars to each other.

[0061] In one embodiment, an avoidance groove 120 is provided on the inner side wall of the water tank 100, and both the limiting member 400 and the mounting bracket 500 are disposed in the avoidance groove 120. Thus, by disposing the limiting member 400 and the mounting bracket 500 in the avoidance groove 120, it is equivalent to reducing the protruding height of the limiting member 400 and the mounting bracket 500 relative to the inner side wall of the water tank 100, or the side of the mounting bracket 500 facing away from the bottom of the avoidance groove 120 can be flush with or recessed from the inner side wall of the water tank 100. In this way, there is no need to provide a concave structure on the outer side of the fuselage 200 to avoid the mounting bracket 500 and the limiting member 400, so that the outer shell structure of the fuselage 200 can be simplified, which is beneficial to improving its manufacturing efficiency, and can also avoid occupying the space inside the fuselage 200 when providing the concave structure. Among them, in one embodiment, the support member 300 can also be disposed in the avoidance groove 120 to avoid providing a concave structure on the outer side of the fuselage 200 to avoid the support member 300. Of course, in other embodiments, the avoidance groove 120 may not be provided.

[0062] Further, in one embodiment, the avoidance groove 120 includes a first groove 121 and a second groove 122. The first groove 121 is located above the second groove 122, and the second groove 122 communicates with the first groove 121, that is, the second groove 122 penetrates upward through the lower side wall of the first groove 121. Both the limiting member 400 and the mounting bracket 500 are arranged in the second groove 122. The groove width of the first groove 121 is greater than that of the second groove 122, that is, the width of the first groove 121 along the transverse direction of the inner side wall of the water tank 100 is greater than the width of the second groove 122 along the transverse direction of the inner side wall of the water tank 100. The support member 300 is arranged in the first groove 121, and the lower side surface of the support member 300 abuts against the lower groove wall of the first groove 121 to provide support for the support member 300 through the lower groove wall of the first groove 121. In addition, the upper surface of the mounting bracket 500 is flush with the lower groove wall of the first groove 121, that is, the upper surface of the support portion 580 is flush with the lower groove wall of the first groove 121, so that the lower groove wall of the first groove 121 and the upper surface of the mounting bracket 500 can preferably jointly provide support for the support member 300. It should be noted that the "lower side surface" here means the side surface of the support member 300 facing downward when the support member 300 is in a transverse state. Of course, in other embodiments, the groove width of the first groove 121 can also be the same as that of the first groove 121. At this time, a support protrusion can be arranged in the first groove 121 to provide support for the support member 300.

[0063] Since the floating portion 410 moves upward by generating buoyancy in water, reducing the interference between the floating portion 410 and other structures is beneficial to improving the floating effect of the floating portion 410. For example, in one embodiment, an isolation rib 540 is provided at the bottom of the mounting bracket 500. In the second position, the floating portion 410 abuts against the upper side of the isolation rib 540. Specifically, the mounting protrusion has a bottom plate 590. The bottom plate 590 is arranged on the bottom wall of the water tank 100, and the isolation rib 540 is arranged on the upper surface of the bottom plate 590. When the limiting member 400 is in the second position, the floating portion 410 abuts against the upper side of the isolation rib 540. In this way, it is equivalent to making the bottom of the floating portion 410 spaced from the upper surface of the bottom plate 590, reducing the contact area between the bottom of the floating portion 410 and the upper surface of the bottom plate 590, thereby being able to reduce the adsorption force between the bottom of the floating portion 410 and the upper surface of the bottom plate 590. When there is water in the water tank 100, the floating portion 410 can easily float. And arranging the bottom plate 590 on the bottom wall of the water tank 100 can also provide support for the mounting bracket 500 through the bottom wall of the water tank 100. Of course, in other embodiments, the bottom plate 590 can also be spaced from the bottom wall of the water tank 100. In addition, the bottom plate 590 can be not arranged, and the isolation rib 540 can be arranged on the groove wall of the limiting groove 510 to reduce the contact area between the bottom of the floating portion 410 and the bottom wall of the water tank 100.

[0064] In one embodiment, the mounting bracket 500 is detachably connected to the water tank 100. In this way, when the limiting member 400 or the mounting bracket 500 fails or is damaged, it is convenient to replace and maintain the limiting member 400 and the mounting bracket 500. Compared with the method of replacing the entire water tank 100, only the limiting member 400 or the mounting bracket 500 can be replaced, which can reduce costs. Of course, in other embodiments, the mounting bracket 500 and the water tank 100 may also be non-detachably connected.

[0065] Among them, the mounting bracket 500 and the water tank 100 can be snap-connected. For example, in one embodiment, a snap 550 is provided at the upper end of the mounting bracket 500, and a slot is provided on the inner side wall of the water tank 100, and the snap 550 is snap-connected to the slot. In this way, the structures of the water tank 100 and the mounting bracket 500 and the installation process are relatively simple, which is beneficial to simplifying the structures of the water tank 100 and the mounting bracket 500 and improving the installation efficiency. Of course, in other embodiments, the mounting bracket 500 can also be fixed to the water tank 100 by screws.

[0066] Further, in one embodiment, a limiting convex portion 140 is provided on the bottom wall of the water tank 100, and a jack 560 is provided at the bottom of the mounting bracket 500, and the limiting convex portion 140 is in plug-in fit with the jack 560. In this way, when assembling the mounting bracket 500, the jack 560 can be first plugged into the limiting convex portion 140, and then the snap 550 can be snap-connected into the slot. The installation is convenient, and the number of snaps 550 is reduced, which is beneficial to simplifying the structure of the mounting bracket 500. Moreover, through the plug-in fit of the jack 560 and the limiting convex portion 140, the bottom offset of the mounting bracket 500 can be better restricted. In one embodiment, the jack 560 is provided on the bottom plate 590. In other embodiments, the bottom of the mounting bracket 500 can also be snap-connected to the inner side wall or the bottom wall of the water tank 100.

[0067] In one embodiment, a water-receiving groove 130 is provided on the bottom wall of the water tank 100, and the water-receiving groove 130 is located below the floating portion 410; at the second position, a part of the floating portion 410 is received in the water-receiving groove 130. That is, when the fuselage 200 is in an idle state, the limiting member 400 is in the second position, and the bottom of the floating portion 410 is received in the water-receiving groove 130. At this time, the bottom of the floating portion 410 can extend into the water-receiving groove 130, or the bottom surface of the floating portion 410 is flush with the edge of the notch of the water-receiving groove 130 (equivalent to the bottom wall of the water tank 100). When the fuselage 200 starts to work and the dehumidified water flows into the water tank 100, the dehumidified water will first flow into the water-receiving groove 130, so that the floating portion 410 will first contact the dehumidified water in the water-receiving groove 130 and generate an upward buoyancy force. With such a setting, even when there is less dehumidified water in the water tank 100, the floating portion 410 can be made to float upward. Of course, in other embodiments, the water-receiving groove 130 may not be provided.

[0068] Please refer to again Figure 7 and Figure 8 In one embodiment, a limiting protrusion 320 is provided on the upper side of the support member 300, and a positioning groove (not shown in the figure) is provided at the bottom of the fuselage 200. When the support member 300 can support the lower end of the fuselage 200, the limiting protrusion 320 is inserted and matched with the positioning groove. In this way, the placement of the fuselage 200 can be positioned, and the sliding of the fuselage 200 on the support member 300 can also be restricted, so as to reduce the possibility of the fuselage 200 contacting the water tank 100 and reduce the situation of abrasion and damage between the fuselage 200 and the water tank 100. It should be noted that the "upper side" here means that when the support member 300 is in a horizontal state, the side of the support member 300 facing upward, and the bottom of the fuselage 200 abuts against the upper side. One or more limiting protrusions 320 can be provided on the support member 300. For example, two limiting protrusions 320 can be provided on the support member 300, and each limiting protrusion 320 can be correspondingly inserted and matched with a positioning groove. In addition, in one embodiment, a plurality of positioning grooves are provided at the bottom of the fuselage 200, and the plurality of positioning grooves are distributed along the circumferential direction of the bottom of the fuselage 200. For example, when the fuselage 200 is square, positioning grooves are provided at the side positions of the bottom of the fuselage 200 to ensure that when the fuselage 200 rotates by multiple angles relative to the water tank 100, there are always positioning grooves that cooperate with the limiting protrusions 320. Additionally, in other embodiments, positioning grooves can also be provided on the support member 300, and limiting protrusions 320 can be provided at the bottom of the fuselage 200.
