Description

Technical Field

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

[0002] With the improvement of living standards, heaters have become an essential home appliance for many families in winter. Heaters convert electrical energy or other chemical energy into heat energy and transfer heat through radiation and convection, providing a warm environment and improving indoor comfort. Compared with air conditioners, heaters require less electricity to achieve the heating effect, making them more time-saving and energy-efficient.

[0003] However, existing heaters generally only allow users to change the direction of heat transfer by rotating or oscillating the main body of the heater. Users cannot easily adjust the height of the heating end, resulting in a poor user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a heating device to address the problem that existing heaters can only change the direction of heat transfer by rotating or oscillating the main body, making it difficult for users to conveniently adjust the height of the heating end, resulting in a poor user experience.

[0005] A heating device includes: a mounting bracket, the mounting bracket including a telescopic part and a base, the telescopic part being disposed on the top of the base; a heating body, the rear wall of the heating body having a connecting seat formed thereon; and a rotating assembly, the rotating assembly including a rotating connector and a rotating shaft, one end of the rotating connector being rotatably connected to the connecting seat via the rotating shaft, and the other end of the rotating connector being rotatably connected to the telescopic part, the telescopic part being configured to drive the heating body and the rotating assembly to perform telescopic lifting and lowering movements relative to the base, and the heating body being able to swing relative to the mounting bracket in the front-back direction and / or the left-right direction.

[0006] This application provides a heating device with a rotating connector that can be rotatably connected to both the heating body and the telescopic part of the mounting bracket. This simple structure allows for multi-dimensional and multi-angle oscillation of the heating body. When the heating body oscillates forward and backward via the rotating shaft and the rotating connector, it meets the user's need to adjust the tilt angle and wind direction. Simultaneously, the rotating connector and the telescopic part allow for left and right oscillation of the heating body, making the heating device better adaptable to both horizontal and vertical use scenarios. Furthermore, the telescopic part also allows for direct raising and lowering of the heating body, enabling users to easily adjust the height as needed to meet the heating needs of different consumers.

[0007] In one embodiment, the rotating connector has a mounting groove on the side facing the heating body, at least a portion of the connecting seat is located in the mounting groove, the connecting seat is rotatably connected to the inner wall of the mounting groove via the rotating shaft so that the heating body can swing back and forth relative to the rotating connector, the inner wall of the mounting groove has a plurality of limiting grooves, the plurality of limiting grooves are circumferentially spaced around the rotating shaft, the rotating assembly further includes a first limiting assembly, the first limiting assembly includes a first limiting post and a first spring, the connecting seat has a positioning groove formed on the side facing the plurality of limiting grooves, one end of the first limiting post is connected to the bottom wall of the positioning groove via the first spring, and the other end of the first limiting post can be selectively fitted and installed with one of the plurality of limiting grooves. By adopting the above structure, when the heating body rotates under the action of external force, it will drive the first limiting post to move along the side wall of the mounting groove, causing the first spring to be compressed and deformed and drive the first limiting post to leave the limiting groove, thereby allowing the heating body to rotate smoothly. When the external force disappears, the first limiting post will quickly extend into another limiting groove under the action of the elastic restoring force provided by the first spring. Through the limiting cooperation formed by the first limiting post and the limiting groove, the heating body can be locked at the tilt angle required by the user.

[0008] In one embodiment, the bottom wall of the mounting groove is provided with a stop rib, and the outer wall of the connecting seat is formed with a limiting rib. The limiting rib and the stop rib abut against each other to restrict the swing of the heating body relative to the rotating connector. By providing stop ribs and limiting ribs on the bottom wall of the mounting groove and the connecting seat respectively, when the heating body swings relative to the rotating connector under the action of external force until the stop rib and the limiting rib abut against each other, the stop rib and the limiting rib will cooperate to limit the swing of the heating body, thereby preventing the heating body from exceeding the preset swing range and causing the locking function of the first limiting component to fail.

[0009] In one embodiment, the number of stop ribs is two, and the two stop ribs are distributed at intervals along the height direction.

[0010] In one embodiment, the rotating connector is rotatably connected to the telescopic part to drive the heating body to swing left and right relative to the mounting bracket. The rotating assembly further includes a second limiting assembly, which includes a limiting member and a limiting rack. The limiting rack is disposed on the telescopic part, and the limiting member is disposed on the rotating connector. The limiting member has locking teeth that mesh with the limiting rack. By adopting the above structure, the limiting member has locking teeth that mesh with the limiting rack disposed on the telescopic part. When the heating body swings left and right under the action of external force, the rotating connector will synchronously drive the locking teeth to move relative to the limiting rack. When the external force disappears, the locking teeth will engage with any locking position of the limiting rack, restricting the free rotation of the rotating connector and locking the heating body at the required swing angle.

[0011] In one embodiment, the limiting rack is annular and is coaxial with the rotation axis of the rotating connector.

[0012] In one embodiment, the limiting member has a first arc-shaped hole, and the telescopic part protrudes to form a sliding post, which is slidably inserted into the first arc-shaped hole. Through the cooperation of the sliding post and the first arc-shaped hole, when the sliding post slides to the end of the first arc-shaped hole, a limiting effect is achieved, preventing the rotating connector from causing the heating body to swing beyond the preset swing range in the left-right direction, while also providing support, allowing the heating body to better maintain stability at its maximum angle.

[0013] In one embodiment, the telescopic part is provided with a shaft hole, the rotating connector and the limiting member are respectively located on both sides of the shaft hole, the end of the rotating connector away from the heating body passes through the shaft hole and is connected to the limiting member, and the limiting member abuts against the telescopic part.

[0014] In one embodiment, the telescopic part includes an upper bracket and a lower bracket. The lower bracket is disposed on the base. The end of the rotating connector away from the heating body is rotatably connected to the upper bracket. One of the upper bracket and the lower bracket is provided with a sliding groove arranged along the height direction, and the other of the upper bracket and the lower bracket forms a limiting rod, which is slidably inserted into the sliding groove. By providing matching limiting rods and sliding grooves on the upper bracket and the lower bracket respectively, the sliding insertion of the limiting rod in the sliding groove can limit the movement direction of the upper bracket, making the lifting and lowering of the rotating component and the heating body driven by the upper bracket more stable.

[0015] In one embodiment, the outer wall of the limiting rod is provided with a plurality of limiting holes, which are spaced apart along the height direction. The telescopic part further includes a third limiting assembly, which includes a limiting housing, a second limiting post, and a second spring. The limiting housing is disposed on the outer wall of the slide groove and has a mounting cavity. The second limiting post is partially located in the mounting cavity. One end of the second limiting post is connected to the inner wall of the mounting cavity through the second spring, and the other end of the second limiting post extends into the slide groove and can be selectively inserted into one of the plurality of limiting holes. By adopting the above structure, when the upper bracket and the heating body move up and down under the action of external force, the second limiting post will be driven to slide along the side wall of the limiting rod, so that the second spring is compressed or stretched and deformed, and the second limiting post will be driven to leave the limiting hole, thereby allowing the heating body to move up and down smoothly. When the external force disappears, the second limiting post will quickly extend into another limiting hole under the action of the elastic restoring force provided by the second spring. Through the limiting cooperation formed by the second limiting post and the limiting hole, the heating body can be locked at the height required by the user.

[0016] In one embodiment, the third limiting assembly further includes a locking member and a third spring. The locking member is partially located in the mounting cavity, and one end of the locking member is connected to the inner wall of the mounting cavity via the third spring. The end of the second limiting post away from the limiting rod is connected to the locking member. The locking member is configured to be telescopically movable relative to the limiting housing and has at least an unlocked position and a locked position. When the locking member is in the unlocked position, the second limiting post is disengaged from the limiting hole. When the locking member is in the locked position, the second limiting post is inserted into one of the plurality of limiting holes. By adopting the above structure, when the locking member is in the locked position, it will drive the second limiting post into the limiting hole, keeping the upper and lower housings locked. When the user performs a lifting operation on the heating unit, the locking member can be moved to the unlocked position first. The contact position between the locking member and the second limiting post changes, causing the pressure of the locking member on the second limiting post to decrease. As a result, under the elastic restoring force of the second spring, the second limiting post leaves the limiting hole, thereby releasing the lock between the upper and lower housings. This makes the lifting operation of the heating unit smoother and easier. When the lifting is in place, the user releases the locking member, and the locking member can be reset under the force of the third spring, restoring the locking function of the second limiting post.

[0017] In one embodiment, the direction of movement of the locking member is perpendicular to the direction of movement of the second limiting post. The locking member has an inclined surface on the side facing the second limiting post, and this inclined surface slides against the end of the second limiting post away from the limiting rod. By employing this structure, when the locking member moves between the locked and unlocked positions, the contact position between the inclined surface and the second limiting post changes. This alters the force exerted by the locking member on the second limiting post, and, with the assistance of the second spring, easily changes the position of the second limiting post.

[0018] In one embodiment, the second limiting post includes a post body and a limiting block. The limiting block is disposed on the side of the post body away from the limiting post. The limiting block is connected to the locking member. The third spring is sleeved on the outside of the post body. One end of the third spring abuts against the limiting block, and the other end of the third spring abuts against the inner wall of the mounting cavity near the limiting post.

[0019] In one embodiment, there are two slides, and the number of limiting rods corresponds to the number of slides, with each rod in a one-to-one arrangement. The third limiting component is located between the two limiting rods. By adopting the above structure, the two limiting rods provide better support for the heating element, making the lifting and lowering of the heating element and the upper support more stable.

[0020] In one embodiment, the outer side wall of the upper bracket is recessed to form a clearance groove, and the limiting housing is disposed in the clearance groove. By providing a clearance groove for installing the third limiting component, the third limiting component is less exposed while facilitating user operation of the locking component. This reduces the risk of the locking component being accidentally moved to the unlock position, which could cause the locking function of the second limiting post to fail.

[0021] In one embodiment, a drive assembly is further included, which is disposed on the base. The output end of the drive assembly is connected to the telescopic part to drive the telescopic part to rotate relative to the base. By employing the above structure, the drive assembly can drive the telescopic part to rotate relative to the base, thereby allowing the heating unit to rotate under the influence of the telescopic part, achieving omnidirectional radiant heat and meeting the heating needs of consumers.

[0022] In one embodiment, the base has a receiving cavity, the top wall of which has a second arc-shaped hole communicating with the receiving cavity. The driving assembly includes a motor and a crank. The motor is disposed in the receiving cavity. The end of the telescopic part away from the heating body extends into the receiving cavity through the second arc-shaped hole and is connected to the output shaft of the motor through the crank. The crank is configured to cooperate with the second arc-shaped hole under the drive of the motor, thereby driving the telescopic part to rotate relative to the base. Attached Figure Description

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] The heating device according to some embodiments of the present invention is described below with reference to the accompanying drawings.

[0040] like Figures 1 to 3 As shown, this embodiment discloses a heating device, including: a mounting bracket 1, which includes a telescopic part 11 and a base 12, with the telescopic part 11 disposed on the top of the base 12; a heating body 2, with a connecting seat 21 formed on the rear wall of the heating body 2; and a rotating assembly 3, which includes a rotating connector 31 and a rotating shaft 32. One end of the rotating connector 31 is rotatably connected to the connecting seat 21 via the rotating shaft 32, and the other end of the rotating connector 31 is rotatably connected to the telescopic part 11. The telescopic part 11 is configured to drive the heating body 2 and the rotating assembly 3 to perform telescopic lifting and lowering movements relative to the base 12, and the heating body 2 can swing relative to the mounting bracket 1 in the front-back direction and / or left-right direction.

[0041] This application provides a heating device with a rotating connector 31 that can be rotatably connected to both the heating body 2 and the telescopic part 11 of the mounting bracket 1. This simple structure allows for multi-dimensional and multi-angle swinging of the heating body 2. When the heating body 2 swings back and forth via the rotating shaft 32 and the rotating connector 31, it meets the user's need to adjust the tilt angle and wind direction. Simultaneously, the rotating connector 31 and the telescopic part 11 can also achieve left and right swinging of the heating body 2, making the heating device better adaptable to both horizontal and vertical use scenarios. Furthermore, the telescopic part 11 allows for direct raising and lowering of the heating body 2, enabling users to easily adjust its height as needed to meet the heating needs of different consumers.

[0042] like Figures 2 to 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the rotating connector 31 is provided with an installation groove 301 on the side facing the heating body 2, at least a portion of the connecting seat 21 is located in the installation groove 301, the connecting seat 21 is rotatably connected to the inner wall of the installation groove 301 through the rotating shaft 32 so that the heating body 2 can swing back and forth relative to the rotating connector 31, the inner wall of the installation groove 301 is provided with a plurality of limiting grooves 302, the plurality of limiting grooves 302 are distributed circumferentially around the rotating shaft 32, the rotating assembly 3 also includes a first limiting assembly 33, the first limiting assembly 33 includes a first limiting post 331 and a first spring 332, the connecting seat 21 is formed with a positioning groove 201 on the side facing the plurality of limiting grooves 302, one end of the first limiting post 331 is connected to the bottom wall of the positioning groove 201 through the first spring 332, and the other end of the first limiting post 331 can be selectively fitted and installed with one of the plurality of limiting grooves 302. By adopting the above structure, when the heating body 2 rotates under the action of external force, it will drive the first limiting post 331 to move along the side wall of the mounting groove 301, so that the first spring 332 is compressed and deformed and drives the first limiting post 331 to leave the limiting groove 302, thereby allowing the heating body 2 to rotate smoothly. When the external force disappears, the first limiting post 331 will quickly extend into another limiting groove 302 under the action of the elastic restoring force provided by the first spring 332. Through the limiting cooperation formed by the first limiting post 331 and the limiting groove 302, the heating body 2 can be locked at the tilt angle required by the user.

[0043] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bottom wall of the mounting groove 301 is provided with a stop rib 311, and the outer wall of the connecting seat 21 is formed with a limiting rib 211. The limiting rib 211 and the stop rib 311 abut against each other to restrict the swing of the heating body 2 relative to the rotating connecting member 31. By providing the stop rib 311 and the limiting rib 211 on the bottom wall of the mounting groove 301 and the connecting seat 21 respectively, when the heating body 2 swings relative to the rotating connecting member 31 under the action of external force until the stop rib 311 and the limiting rib 211 abut against each other, the stop rib 311 and the limiting rib 211 will cooperate to limit the swing of the heating body 2, thereby preventing the heating body 2 from exceeding the preset swing range and causing the locking function of the first limiting component 33 to fail.

[0044] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of stop ribs 311 is two, and the two stop ribs 311 are distributed at intervals along the height direction.

[0045] like Figure 4 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the rotating connector 31 is rotatably connected to the telescopic part 11 so that the heating body 2 can swing left and right relative to the mounting bracket 1; the rotating component 3 also includes a second limiting component 34, which includes a limiting member 341 and a limiting rack 342. The limiting rack 342 is disposed on the telescopic part 11, and the limiting member 341 is disposed on the rotating connector 31. The limiting member 341 is provided with a locking tooth, which engages with the limiting rack 342. By adopting the above structure, the limiting member 341 is provided with a locking tooth, which engages with the limiting rack 342 provided on the telescopic part 11. When the heating body 2 swings left and right under the action of external force, the rotating connecting member 31 will synchronously drive the locking tooth to move relative to the limiting rack 342. When the external force disappears, the locking tooth will engage with any locking position of the limiting rack 342, restricting the free rotation of the rotating connecting member 31, so that the heating body 2 can be locked at the required swing angle.

[0046] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting rack 342 is annular, and the limiting rack 342 is coaxially arranged with the rotation axis of the rotating connector 31.

[0047] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting member 341 is provided with a first arc-shaped hole 303, and the telescopic part 11 protrudes to form a sliding column 1111, which is slidably inserted into the first arc-shaped hole 303. Through the cooperation of the sliding column 1111 and the first arc-shaped hole 303, when the sliding column 1111 slides to the end of the first arc-shaped hole 303, a limiting effect can be formed to prevent the rotating connector 31 from causing the heating body 2 to swing in the left and right directions beyond the preset swing range. At the same time, it can also provide a supporting effect, so that the heating body 2 can better maintain stability at the maximum angle.

[0048] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the telescopic part 11 is provided with a shaft hole, the rotating connector 31 and the limiting member 341 are respectively located on both sides of the shaft hole, the end of the rotating connector 31 away from the heating body 2 passes through the shaft hole and is connected to the limiting member 341, and the limiting member 341 abuts against the telescopic part 11.

[0049] like Figure 3 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the telescopic part 11 includes an upper support 111 and a lower support 112. The lower support 112 is disposed on the base 12. The end of the rotating connector 31 away from the heating body 2 is rotatably connected to the upper support 111. One of the upper support 111 and the lower support 112 is provided with a sliding groove 101 arranged along the height direction. The other of the upper support 111 and the lower support 112 forms a limiting rod 1121, which is slidably inserted into the sliding groove 101. By providing matching limiting rods 1121 and sliding grooves 101 on the upper support 111 and the lower support 112 respectively, the sliding insertion of the limiting rod 1121 into the sliding groove 101 can limit the movement direction of the upper support 111, making the lifting and lowering of the rotating component 3 and the heating body 2 driven by the upper support 111 more stable.

[0050] like Figure 6 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer wall of the limiting rod 1121 is provided with a plurality of limiting holes 102, the plurality of limiting holes 102 are distributed at intervals along the height direction, the telescopic part 11 also includes a third limiting component 113, the third limiting component 113 includes a limiting housing 1131, a second limiting post 1132 and a second spring 1133, the limiting housing 1131 is disposed on the outer wall of the slide groove 101, the limiting housing 1131 is provided with a mounting cavity 103, the second limiting post 1132 is partially located in the mounting cavity 103, one end of the second limiting post 1132 is connected to the inner wall of the mounting cavity 103 through the second spring 1133, the other end of the second limiting post 1132 extends into the slide groove 101 and can be selectively inserted into one of the plurality of limiting holes 102. By adopting the above structure, when the upper bracket 111 and the heating body 2 move up and down under the action of external force, the second limiting post 1132 will be driven to slide along the side wall of the limiting rod 1121, so that the second spring 1133 is squeezed or stretched and deformed, and the second limiting post 1132 will be driven to leave the limiting hole 102, thereby allowing the heating body 2 to move up and down smoothly. When the external force disappears, the second limiting post 1132 will quickly extend into another limiting hole 102 under the action of the elastic restoring force provided by the second spring 1133. Through the limiting cooperation between the second limiting post 1132 and the limiting hole 102, the heating body 2 can be locked at the height required by the user.

[0051] like Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the third limiting component 113 also includes a locking member 1134 and a third spring 1135. The locking member 1134 is partially located in the mounting cavity 103. One end of the locking member 1134 is connected to the inner wall of the mounting cavity 103 through the third spring 1135. One end of the second limiting post 1132 away from the limiting rod 1121 is connected to the locking member 1134. The locking member 1134 is configured to be able to extend and retract relative to the limiting housing 1131 and has at least an unlocked position and a locked position. When the locking member 1134 is in the unlocked position, the second limiting post 1132 leaves the limiting hole 102. When the locking member 1134 is in the locked position, the second limiting post 1132 is inserted into one of the plurality of limiting holes 102. By adopting the above structure, when the locking member 1134 is in the locked position, the locking member 1134 will drive the second limiting post 1132 to extend into the limiting hole 102, so that the upper shell and the lower shell are locked. When the user performs the lifting operation on the heating body 2, the locking member 1134 can be moved to the unlocked position first. The contact position between the locking member 1134 and the second limiting post 1132 changes, so the pressure of the locking member 1134 on the second limiting post 1132 decreases. As a result, under the elastic restoring force of the second spring 1133, the second limiting post 1132 leaves the limiting hole 102, thereby releasing the lock between the upper shell and the lower shell, making the lifting operation of the heating body 2 smoother and easier. When the lifting is in place, the user releases the locking member 1134, and the locking member 1134 can be reset under the force of the third spring 1135, so that the locking function of the second limiting post 1132 is restored.

[0052] like Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the moving direction of the locking member 1134 is perpendicular to the moving direction of the second limiting post 1132, and an inclined surface is formed on the side of the locking member 1134 facing the second limiting post 1132, the inclined surface slidingly abutting against the end of the second limiting post 1132 away from the limiting rod 1121. By adopting the above structure, when the locking member 1134 moves between the locked position and the unlocked position, the abutting position of the inclined surface against the second limiting post 1132 will change, thereby changing the force applied by the locking member 1134 to the second limiting post 1132, and easily changing the position of the second limiting post 1132 through the cooperation of the second spring 1133.

[0053] like Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines: the second limiting post 1132 includes a post body 11321 and a limiting block 11322. The limiting block 11322 is disposed on the side of the post body 11321 away from the limiting post. The limiting block 11322 is connected to the locking member 1134. The third spring 1135 is sleeved on the outside of the post body 11321. One end of the third spring 1135 abuts against the limiting block 11322, and the other end of the third spring 1135 abuts against the inner wall of the mounting cavity 103 near the limiting post.

[0054] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of slide grooves 101 is two, the number of limiting rods 1121 is the same as the number of slide grooves 101 and they are arranged in a one-to-one correspondence, and the third limiting component 113 is located between the two limiting rods 1121. By adopting the above structure, the two limiting rods 1121 can better support the heating body 2, making the lifting and lowering of the heating body 2 and the upper support 111 more stable.

[0055] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a relief groove 104 is formed in the outer side wall of the upper bracket 111, and the limiting housing 1131 is disposed in the relief groove 104. By providing the relief groove 104 for installing the third limiting component 113, the exposure of the third limiting component 113 can be reduced while facilitating user operation of the locking member 1134. This reduces the risk of the locking member 1134 being accidentally touched to the unlock position, which could cause the locking function of the second limiting post 1132 to fail.
