[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In order to solve the problem in the prior art that electrical equipment may move or even fall over due to accidental contact, the present invention provides a caster assembly and an electrical equipment, wherein the electrical equipment includes a base 1 and a caster assembly 2, the caster assembly 2 is connected to the base 1, and the caster assembly 2 is the caster assembly described above and below.

[0040] It should be noted that, in the present application, the electrical device is a dehumidifier. The following description will be made using a dehumidifier as an example. Of course, the electrical device may also be a humidifier, an electric heater, etc.

[0041] like Figures 1 to 10 As shown, the caster assembly 2 includes a support structure 10 and a caster structure 20, which are movably connected to each other. By adjusting at least one of the support structure 10 and the caster structure 20, one of the support structure 10 and the caster structure 20 can be brought into contact with the ground; wherein, when the support structure 10 is in contact with the ground, the caster structure 20 is in a suspended state, and the support structure 10 plays a supporting role; when the caster structure 20 is in contact with the ground, the support structure 10 is in a suspended state, and the caster structure 20 is movably arranged relative to the ground.

[0042] The present application provides an electrical device having a caster assembly, wherein the caster assembly is configured to include a support structure 10 and a caster structure 20, and the support structure 10 and the caster structure 20 are movably connected. In this way, at least one of the support structure 10 and the caster structure 20 is adjusted so that one of the support structure 10 and the caster structure 20 is in contact with the ground.

[0043] Specifically, when the user needs the electrical equipment to perform dehumidification operations in a fixed position, the support structure 10 of the caster assembly is in contact with the ground, and the caster structure 20 is in a suspended state. The support structure 10 plays a supporting role to prevent the electrical equipment from moving or even tipping over due to force; when the user needs to move the electrical equipment, the caster structure 20 of the caster assembly is in contact with the ground, and the support structure 10 is in a suspended state. The caster structure 20 is movably arranged relative to the ground, so that the electrical equipment is in rolling contact with the ground, ensuring the convenience of movement of the electrical equipment.

[0044] like Figure 3 、 Figure 6 and Figure 9 As shown, the support structure 10 is sleeved on a portion of the outer periphery of the caster structure 20, and the support structure 10 is movably arranged relative to the caster structure 20. In this way, since the support structure 10 is sleeved on a portion of the outer periphery of the caster structure 20, the support structure 10 can be brought into contact with the ground, or the caster structure 20 can be brought into contact with the ground, by moving the support structure 10, which is convenient and quick to operate.

[0045] It should be noted that, in this application, in order to ensure the convenience of adjusting the support structure 10, as shown in FIG. Figures 1 to 10 As shown, the moving direction of the support structure 10 is perpendicular to the ground. Thus, the support structure 10 can be suspended in the air by simply moving it upward, thereby allowing the caster structure 20 to contact the ground, or the support structure 10 can be suspended in the air by simply moving it downward, thereby allowing the support structure 10 to contact the ground.

[0046] Optionally, the support structure 10 and the caster structure 20 are snap-fitted. Thus, after the position of the support structure 10 is adjusted, the caster structure 20 is in contact with the ground, and the support structure 10 is suspended in the air, thereby ensuring the stability of the connection between the support structure 10 and the caster structure 20; or, when the support structure 10 is in contact with the ground and the caster structure 20 is suspended in the air, thereby ensuring the stability of the connection between the support structure 10 and the caster structure 20.

[0047] Optionally, the caster structure 20 has a first clip 21, and the support structure 10 has a second clip that cooperates with the first clip 21. At least one of the first clip 21 and the second clip is provided in a plurality of ways, so that different first clips 21 and second clips cooperate and engage to keep the support structure 10 or the caster structure 20 in the suspended state. In this way, while ensuring the reliability of the connection between the support structure 10 and the caster structure 20, it is also ensured that different first clips 21 and second clips cooperate and engage to keep the support structure 10 or the caster structure 20 in the suspended state.

[0048] It should be noted that, in the present application, considering that there are two engaging positions during the movement of the support structure 10, the support structure 10 can be in contact with the ground or the caster structure 20 can be in contact with the ground. Figures 1 to 3 、 Figure 5 、 Figure 6 and Figure 9 As shown, the support structure 10 has two second clips. When the support structure 10 is in contact with the ground, the first clip 21 engages with one of the two second clips. When the caster structure 20 is in contact with the ground, the first clip 21 engages with the other of the two second clips. This ensures the reliability of the adjustment of the support structure 10.

[0049] It should be noted that in an embodiment (not shown) of the present application, considering that two engaging positions are sufficient to ensure that the support structure 10 or the caster structure 20 is in contact with the ground during movement, the caster structure 20 has two first engaging members 21. When the support structure 10 is in contact with the ground, the second engaging member engages with one of the two first engaging members 21; when the caster structure 20 is in contact with the ground, the second engaging member engages with the other of the two first engaging members 21. This ensures the adjustable reliability of the support structure 10.

[0050] like Figures 5 to 10 As shown, the first clamping member 21 includes a retractable lock 211, and the second clamping member is a first opening slot 11. When the support structure 10 moves, the lock 211 is in a retracted state. When the support structure 10 moves into place, the lock 211 is in an extended state and extends from the first opening slot 11. In this way, by setting the clamping cooperation mode between the first clamping member 21 and the second clamping member to the cooperation mode between the lock 211 and the first opening slot 11, while ensuring the reliability of the clamping connection between the first clamping member 21 and the second clamping member, it also ensures that the structures of the first clamping member 21 and the second clamping member are sufficiently simple, easy to process and manufacture, thereby promoting the economic efficiency of the electrical equipment.

[0051] like Figures 1 to 3 ,like Figure 5 、 Figure 6 and Figure 9 As shown, the support structure 10 includes a first cylindrical body 12 and a second cylindrical body 13 that are connected and coaxially arranged. The caster structure 20 includes a shaft 22 and a hub 23 that are connected. The shaft 22 is assembled with the first cylindrical body 12, and the second cylindrical body 13 is used to accommodate the hub 23. This ensures that the overall volume of the caster assembly 2 is sufficiently small, avoiding occupying a large installation space.

[0052] It should be noted that, in this application, considering that the caster structure 20 includes a shaft 22 and a hub 23 connected to each other, and the volume of the hub 23 is larger than the volume of the shaft 22, in order to ensure that the second cylinder 13 can effectively accommodate the hub 23, as shown in FIG. Figures 1 to 3 ,like Figure 5 、 Figure 6 and Figure 9 As shown, the cross-sectional area of ​​the second barrel 13 is greater than the cross-sectional area of ​​the first barrel 12. In this way, it is ensured that the second barrel 13 has enough space to accommodate the wheel hub 23.

[0053] like Figures 1 to 3 ,like Figure 5 、 Figure 6 and Figure 9 As shown, the support structure 10 includes a first cylinder 12 and a second cylinder 13 that are connected and coaxially arranged. The caster structure 20 includes a shaft 22 and a hub 23 that are connected. The shaft 22 is assembled with the first cylinder 12, and the second cylinder 13 is used to accommodate the hub 23. The first clamping member 21 is arranged on the shaft 22, and the second clamping member is arranged on the first cylinder 12. In this way, since the shaft 22 is assembled with the first cylinder 12, by arranging the first clamping member 21 on the shaft 22 and the second clamping member on the first cylinder 12, the reliability of the clamping fit between the first clamping member 21 and the second clamping member is ensured.

[0054] like Figures 5 to 10 As shown, there are two first opening grooves 11, and the two first opening grooves 11 are arranged at intervals along the axial direction of the first cylinder 12. When the support structure 10 is moved upward or downward, the lock buckle 211 is in a retracted state. A slide groove 122 is formed on the cylinder wall surface of the first cylinder 12 between the two first opening grooves 11. The slide groove 122 plays a guiding role for the lock buckle 211 and can also ensure that the support structure 10 moves smoothly upward or downward.

[0055] like Figure 3 、 Figure 5 and Figure 8As shown, the shaft body 22 includes a connecting shaft 221 and an assembly cylinder 222. One end of the connecting shaft 221 passes through the assembly cylinder 222 and is connected to the wheel hub 23. The second end of the connecting shaft 221 has a limiting boss 2211. The first cylinder 12 has a limiting retaining ring 121. When the caster structure 20 contacts the ground and the support structure 10 has two second clamping parts, the limiting retaining ring 121 abuts against the limiting boss 2211, and the first clamping part 21 engages with the second clamping part of the two second clamping parts that is close to the second cylinder 13. In this way, when the support structure 10 moves into place and the caster structure 20 contacts the ground, the limiting retaining ring 121 abuts against the limiting boss 2211, and the first clamping part 21 engages with the second clamping part of the two second clamping parts that is close to the second cylinder 13. This helps prevent the support structure 10 from moving up and down and ensures that the support structure 10 can remain stably suspended.

[0056] like Figure 5 、 Figure 7 and Figure 9 As shown, the caster structure 20 also includes a supporting rib 24, which is provided on the shaft 22 and is located below the first clip 21. When the support structure 10 is in contact with the ground and the support structure 10 has two second clips, the supporting rib 24 engages with the second clip close to the second cylinder 13 of the two second clips, and the first clip 21 engages with the second clip away from the second cylinder 13 of the two second clips. In this way, when the support structure 10 moves into position and contacts the ground, and the caster structure 20 is in a suspended state, the supporting rib 24 engages with the second clip close to the second cylinder 13 of the two second clips, and the first clip 21 engages with the second clip away from the second cylinder 13 of the two second clips. This helps prevent the support structure 10 from moving up and down, and ensures that the support structure 10 can maintain a stable state of contact with the ground.

[0057] like Figures 3 to 6 、 Figure 9 As shown, the support rib 24 and the first clamping member 21 are spaced apart along the axial direction of the shaft 22. The axial direction of the shaft 22 is also the movement direction of the support structure 10, ensuring that the first open groove 11 located below the support structure 10 can abut against the support rib 24 when the support structure 10 moves downward.

[0058] like Figures 3 to 6 、 Figure 9As shown, the caster structure 20 also includes a limiting rib 25, which is provided on the shaft body 22 and located below the supporting rib 24. The limiting rib 25 and the supporting rib 24 are both located on the same side of the shaft body 22. The second cylinder 13 has an avoidance notch 131, which extends axially along the second cylinder 13 and is used to avoid the supporting rib 24. There are two limiting ribs 25, one of which abuts one side of the avoidance notch 131, and the other of which abuts the other side of the avoidance notch 131 to prevent the support structure 10 from rotating during movement. In this way, the support structure 10 is ensured to only move up and down without rotating during movement, thereby ensuring the reliability of the clamping connection between the first clamping member 21 and the second clamping member.

[0059] like Figure 5 、 Figure 7 and Figure 8 As shown, two second opening grooves 2221 are provided on the cylinder wall of the assembly cylinder 222, and the two second opening grooves 2221 are arranged opposite to each other and are located on the radial sides of the assembly cylinder 222. The first clamping member 21 includes two elastic sheets 212, a fixing pin 213 and two lock buckles 211, wherein the two elastic sheets 212 are arranged opposite to each other, and the two elastic sheets 212 are respectively located on the radial sides of the connecting shaft 221, and a limiting space 100 is formed between the two elastic sheets 212; the fixing pin 213 is used to connect the two elastic sheets 212 and the connecting shaft 221; the two lock buckles 211 are respectively telescopically arranged at the two second opening grooves 2221, and each lock buckle 211 is in the shape of a "F", and one end of each lock buckle 211 with an opening extends into the limiting space 100 and abuts against the two elastic sheets 212. In this way, it is convenient for the user to press the two lock buckles 211 by hand, and the two lock buckles 211 are both subjected to force and squeeze the two elastic sheets 212. The two elastic sheets 212 are deformed and give way under pressure, so that the two lock buckles 211 move inward.

[0060] like Figure 10 As shown, when the two lock buckles 211 move inward, the inclined surface 2111 on the lock buckle 211 cooperates with the guide surface 123 on the first cylinder 12, and the inclination angle of the inclined surface 2111 is different from the inclination angle of the guide surface 123, ensuring that there is line contact between the inclined surface 2111 and the guide surface 123, thereby ensuring that the lock buckle 211 can move inward smoothly.

[0061] like Figure 5 As shown, the support structure 10 also includes a gasket 14, which is connected to the bottom of the second cylinder 13. The gasket 14 protects the bottom of the second cylinder 13. A notch 141 is provided at a position of the gasket 14 opposite to the avoidance notch 131 to ensure the adaptability of the gasket 14 to the bottom of the second cylinder 13.

[0062] like Figure 5As shown, an avoidance recess 132 is formed on the upper surface of the second cylinder 13. When the user manually presses the two lock buckles 211, the avoidance recess 132 serves to avoid the user's hands, thereby ensuring the user's convenience in operation.

[0063] It should be noted that, in the present application, when the support structure 10 is moved downward, when the lock buckle 211 just enters the first opening groove 11 located at the top, the support rib 24 just fits into the first opening groove 11 located at the bottom, as shown in FIG. Figure 3 As shown, the spacing distance between the two first opening grooves 11 is L1. When the wheel hub 23 contacts the ground, the distance from the first opening groove 11 located below to the supporting rib 24 is L2, and L1 = L2.
