[0030] Embodiment 1,

[0031] See also Figure 1 and Figure 2The utility model discloses a swing assembly, including a base 10, a connecting seat 20 and a driving member. A plurality of guide grooves 11 are provided on the base 10, and the guide grooves 11 can extend along the circumference of the base 10. In addition, one end of the connecting seat 20 is formed as a first connecting end, and the other end of the connecting seat 20 is formed as a second connecting end. A plurality of sliding columns 21 and a connecting column 23 are provided on the first connecting end. During assembly, the connecting seat 20 can be rotatably mounted on the base 10 through the connecting column 23, and a plurality of sliding columns 21 pass through the guide grooves 11 one by one and slide in cooperation with the guide grooves 11. A limiting portion is provided at the end of each of the sliding columns 21. After the sliding column 21 passes through the guide grooves 11, the limiting portion can abut against the end surface of the base 10 to prevent the connecting seat 20 from being separated from the base 10.

[0032] The driving member can drive the connecting seat 20 to rotate relative to the base 10 so that the sliding column 21 and the guiding groove 11 are slidably matched.

[0033] On the basis of the above structure, when using the swing assembly of the utility model, a heater body, a fan body, a humidifier body and other equipment can be assembled on the second connection end of the connecting seat 20, and the first connection end of the connecting seat 20 can be rotatably mounted on the base 10 through the connecting column 23, so that the connecting seat 20 can be driven to rotate by the driving member on the base 10, and the rotation of the connecting seat 20 can drive the main body of the device connected thereto to rotate, thereby realizing the adjustment of functions such as blowing direction and blowing angle.

[0034] Specifically, when the connecting seat 20 rotates, since the sliding column 21 of the connecting seat 20 can slide with the guide groove 11 on the base 10, and the guide groove 11 extends along the circumference of the base 10, the connecting seat 20 can be guided by the sliding cooperation between the sliding column 21 and the guide groove 11, and the rotation process is stable.

[0035] During the rotation process, if no limiting portion is provided at the end of the sliding column 21, the sliding column 21 of the connecting seat 20 is easily separated from the guidance of the base 10. Therefore, in this embodiment, the limiting portion at the end of the guide groove 11 can abut against the base 10, thereby preventing the connecting seat 20 from being separated when rotating relative to the base 10.

[0036] In addition, if the sliding column 21 is bolted to the connecting seat 20 to form a sliding structure, since the bolts are easily loosened due to rotation friction during use, when the connecting seat 20 rotates relative to the base 10, the sliding column 21 formed by the bolt structure is easy to loosen, resulting in unstable rotation or collision and noise due to loosening. Therefore, in this embodiment, the sliding column 21 directly set on the connecting seat 20 forms a guide structure, and the limiting part of the sliding column 21 abuts against the end surface of the base 10 to form a limit, thereby reducing the loosening during the rotation process and making the rotation structure more stable.

[0037] Furthermore, in this embodiment, a limiting step 211 can be provided at the end of the sliding column 21, and the limiting step 211 extends from both sides of the sliding column 21. The limiting step 211 can abut against the end surface of the base 10, that is, after the sliding column 21 is assembled to the guide groove 11, the limiting step 211 can pass through the guide groove 11 and abut against the end of the base 10 to form a limiting portion.

[0038] Since the limiting step 211 protrudes from the sliding column 21, when the sliding column 21 is assembled, the sliding column 21 and the guide groove 11 are slidably matched, so the protruding limiting step 211 cannot directly pass through the guide groove 11. Therefore, in this embodiment, the limiting step 211 can be rotated a certain angle to pass through the guide groove 11 and then turned back to abut against the end face of the base 10 during assembly to achieve the anti-slip effect. Alternatively, the limiting step 211 can be set as an elastic rubber block structure. During assembly, the extrusion deformation of the elastic rubber block allows the end of the sliding column 21 to squeeze into the guide groove 11 and then recover by itself to abut against it, thereby preventing slippage.

[0039] In this embodiment, on the basis of the structure of the above-mentioned limit step 211, in order to facilitate the disassembly and assembly of the sliding column 21 and the guide groove 11, a disassembly and assembly notch 111 can be provided at one end of the guide groove 11, and the disassembly and assembly notch 111 is connected with the guide groove 11, and the inner diameter of the disassembly and assembly notch 111 is matched with the outer diameter of the limit step 211.

[0040] Specifically, the inner diameter of the disassembly notch 111 is larger than the inner diameter of the guide groove 11. During assembly, the sliding column 21 can correspond to the position of the disassembly notch 111 at the end of the guide groove 11, and the sliding column 21 can be inserted into the position of the disassembly notch 111. Thereafter, the sliding column 21 slides to the guide groove 11 to achieve rotational guidance.

[0041] When disassembling the sliding column 21 , the sliding column 21 is slid to the position of the disassembly notch 111 , and the sliding column 21 is passed out, and the limiting step 211 passes out through the disassembly notch 111 , and then the sliding column 21 can be taken out.

[0042] It should also be noted that, due to the structure of the disassembly notch 111, the sliding column 21 is easy to slide to the disassembly notch 111 and disengage during the rotation of the connecting seat 20. Therefore, in this embodiment, a limiting column 24 is further provided. Specifically, the connecting seat 20 is provided with a limiting column 24, and the base 10 is provided with a limiting groove 13, which extends along the circumference of the base 10. The limiting column 24 and the limiting groove 13 are slidably matched to keep the extension track of the limiting groove 13 consistent with the extension track of the guide groove 11, and the sliding track length of the limiting column 24 in the limiting groove 13 is shorter than the sliding track length of the sliding column 21 in the guide groove 11, so that the limiting column 24 can abut against the end wall of the limiting groove 13 to prevent the limiting step 211 from sliding to the disassembly notch 111.

[0043] That is, when assembling the connecting seat 20 and the base 10, the sliding column 21 on the connecting seat 20 can first be inserted into the guide groove 11 corresponding to the position of the disassembly notch 111, and then continue to slide to the end wall position corresponding to the limit column 24 and the limit groove 13, and then the limit column 24 is inserted into the limit groove 13. In this way, when the connecting seat 20 rotates relative to the base 10, since the limit column 24 always slides in the limit groove 13, the sliding column 21 always keeps sliding in the guide groove 11 and will not slide to the position of the disassembly notch 111, thereby preventing rotation and disengagement when setting the disassembly notch 111.

[0044] When the connecting seat 20 and the base 10 are disassembled, the limiting column 24 is first separated from the limiting groove 13 , and then the sliding column 21 is slid to the position of the disassembly notch 111 at the end of the guide groove 11 .

[0045] In addition, in the case where the limiting column 24 and the limiting groove 13 are not provided, a structure such as an elastic column or a lock buckle can be directly provided between the disassembly notch 111 and the end of the guide groove 11. During the rotation process, the disassembly notch 111 and the end of the guide groove 11 can be blocked by the elastic column or the lock buckle to prevent the sliding column 21 from sliding to the disassembly notch 111 during the rotation process. When disassembling, the elastic column can be retracted or the lock buckle can be unlocked.

[0046] Furthermore, the driving member in this embodiment includes a driving motor 31 and a rotating arm 32. One end of the rotating arm 32 is connected to the rotating shaft of the motor, and the other end of the rotating arm 32 is detachably hinged to the limiting column 24. In this way, when the connecting seat 20 is driven, the rotating shaft of the driving motor 31 can be rotated to drive the rotating arm 32 to rotate. The rotation of the rotating arm 32 can guide the limiting column 24 to slide relative to the limiting groove 13, thereby guiding the connecting seat 20 to rotate relative to the base 10, so that the rotating arm 32 drives the limiting column 24 to slide along the limiting groove 13, thereby driving the rotation of the connection to increase the rotating force arm, so that the rotation stability is better.

[0047] Of course, the connection base 20 can also be driven by the rotation of the motor to drive the connection column 23. In addition, the rotation of the connection base 20 can also be achieved by driving the connection base 20 with the motor shaft in conjunction with a gear transmission mechanism or a synchronous belt transmission mechanism.

[0048] Furthermore, a connecting head 321 can be provided at the end of the rotating arm 32, and the connecting head 321 can be detachably connected to the limiting column 24. Specifically, a slot can be provided on the connecting head 321, and the limiting column 24 can be inserted into the slot to achieve a detachable connection between the two. Specifically, the connecting head 321 is hinged on the rotating arm 32, so that the limiting column 24 can rotate with the rotating arm 32 after being connected to the connecting head 321, and it is not easy to get stuck during the rotation process.

[0049] Furthermore, in order to facilitate the assembly of the driving member and the base 10, a support column 12 can be provided on the end face of the base 10, and the support column 12 can be detachably connected to the housing of the driving member. Specifically, based on the structure that the driving member has a driving motor 31, a connecting plate can be provided on the housing of the driving motor 31, and a perforation is provided on the connection. After the support column 12 is inserted into the perforation, it is locked with screws, which facilitates disassembly and assembly.

[0050] Further, in this embodiment, three guide grooves 11 are provided on the base 10, and the three guide grooves 11 are spaced apart in the circumferential direction of the base 10. Correspondingly, three sliding posts 21 are provided at the first connection end. During assembly, each sliding post 21 slides with the guide groove 11 in a one-to-one correspondence. Thus, when the connection seat 20 and the base 10 rotate, the three sliding posts 21 slide with respect to the guide groove 11 to achieve rotation guidance, which is triangular-shaped guidance, and thus has better rotation stability.

[0051] Furthermore, the second connection end is provided with a threaded connector 22321, so that a corresponding threaded connection structure can be provided on a device host such as a heater body, a fan body or a humidifier body to realize the disassembly and assembly of the device host and the connection seat 20. Of course, the device host can also be directly assembled to the second connection end of the connection seat 20 by a bolt or other structure, and the specific connection method can be selected according to actual needs.

[0052] Embodiment 2,

[0053] A heater comprises a heater body and the swing assembly of embodiment 1, wherein the bottom end of the heater body is detachably connected to the second connection end. The heater body can be assembled on the second connection end of the connection seat 20, and the first connection end of the connection seat 20 is rotatably mounted on the base 10 through the connection column 23, so that the connection seat 20 can be driven to rotate by the driving member on the base 10, and the rotation of the connection seat 20 can drive the heater body connected thereto to rotate, so as to realize the adjustment of the blowing direction and blowing angle of the warm air.

[0054] Specifically, when the connecting seat 20 rotates, since the sliding column 21 of the connecting seat 20 can slide with the guide groove 11 on the base 10, and the guide groove 11 extends along the circumference of the base 10, the connecting seat 20 can be guided by the sliding cooperation between the sliding column 21 and the guide groove 11, and the rotation process is stable.

[0055] During the rotation process, if no limiting portion is provided at the end of the sliding column 21, the sliding column 21 of the connecting seat 20 is easily separated from the guidance of the base 10. Therefore, in this embodiment, the limiting portion at the end of the guide groove 11 can abut against the base 10, thereby preventing the connecting seat 20 from being separated when rotating relative to the base 10.

[0056] In addition, if the sliding column 21 is bolted to the connecting seat 20 to form a sliding structure, since the bolts are easily loosened due to rotation friction during use, when the connecting seat 20 rotates relative to the base 10, the sliding column 21 formed by the bolt structure is easy to loosen, resulting in unstable rotation or collision and noise due to loosening. Therefore, in this embodiment, the sliding column 21 directly set on the connecting seat 20 forms a guide structure, and the limiting part of the sliding column 21 abuts against the end surface of the base 10 to form a limit, thereby reducing the loosening during the rotation process and making the rotation structure more stable.

[0057] It should be noted that the other structures of the swing assembly in this embodiment are the same as those in Embodiment 1. When applied to a heater, it has the same working process and technical effects as those in Embodiment 1, and will not be described in detail here.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
