Utility Model Content

[0005] The purpose of this invention is to provide a rotatable and adjustable heater with adjustable horizontal angle and a large lateral coverage area of ​​the heating element.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rotatable and adjustable heater, comprising a base body and a heating element assembly, wherein the base body includes a hinge portion, and a rotation positioning structure is provided between the hinge portion and the heating element assembly, the hinge portion and the heating element assembly being rotatably connected through the rotation positioning structure, the rotation positioning structure including a first rotation positioning member, a second rotation positioning member and a spring, the first rotation positioning member being fixed on the hinge portion, the second rotation positioning member being fixed on the heating element assembly, and the end face of the first rotation positioning member facing the second rotation positioning member having a first toothed engagement portion, the second rotation positioning member having a second toothed engagement portion corresponding to the first toothed engagement portion, the spring having a tendency to drive the end faces of the first rotation positioning member and the second rotation positioning member to abut against each other, and to engage the first toothed engagement portion with the second toothed engagement portion to stop rotation.

[0007] By adopting the above technical solution, when the user rotates the heating element assembly, the heating element assembly drives the second rotating positioning member to rotate. The second toothed engagement part pushes the first toothed engagement part to move away from the heating element assembly. At the same time, the spring is compressed. After the rotation is completed, the first rotating positioning member is reset under the action of the spring force, so that the first rotating positioning member abuts against the second rotating positioning member. At this time, the first toothed engagement part and the second toothed engagement part engage to stop the rotation, so that the heating element assembly is fixed at the current angle, which makes it easy to adjust the horizontal angle of the heater and increase the horizontal coverage area when the heater is heating.

[0008] A further feature of this invention is that the second rotating positioning member is fixed in the middle of the heating body assembly, and the second rotating positioning member is located on the side of the heating body assembly close to the base body.

[0009] By adopting the above technical solution, when the heating element assembly rotates, it rotates around the middle of the heating element assembly, and the center of gravity is not easily deviated, thus improving the stability of the heater during use.

[0010] A further feature of this invention is that the base body includes a connecting rod, and a support portion is provided at one end of the heating element assembly away from the second rotating positioning member. The support portion is located on the side of the heating element assembly near the connecting rod. When the heating element assembly rotates relative to the base body to a vertical position, the support portion and the connecting rod provide positioning support.

[0011] By adopting the above technical solution, the bottom of the heating element assembly is positioned and supported by the support part in a vertical state, thereby improving the stability of the heating element assembly when used in a vertical state.

[0012] A further feature of this invention is that the second rotary positioning member has a circumferential positioning post on the side near the heating element assembly, and the heating element assembly has a corresponding positioning groove, with the positioning post and the positioning groove being positioned and engaged.

[0013] By adopting the above technical solution, when the second rotary positioning component is installed, the positioning post is placed in the positioning groove, and the second rotary positioning component is fixedly connected to the heating body assembly, so that the second rotary positioning component can be rotated when the heating body assembly rotates, thereby improving the accuracy and convenience of the positioning and installation of the second rotary positioning component.

[0014] A further feature of this invention is that the second rotary positioning member has an annular slot on the side near the hinge portion, the hinge portion has an annular insertion portion, and the annular insertion portion is positioned and inserted into the annular slot and rotates to engage with the annular slot.

[0015] By adopting the above technical solution, when the heater is installed, the second rotating positioning component is positioned and engaged with the hinge part through the annular slot, and the second rotating positioning component can rotate along the opening direction of the annular slot, thereby improving the ease of installation between the second rotating positioning component and the hinge part.

[0016] A further feature of this invention is that the hinge portion is provided with a first mounting groove, the first mounting groove is provided with an anti-detachment component, the anti-detachment component is fixedly mounted on the second rotary positioning component, the anti-detachment component is rotatably connected to the first mounting groove, and the second rotary positioning component is anti-detached from the hinge portion through the anti-detachment component.

[0017] By adopting the above technical solution, when installing, the user inserts the anti-detachment component along the first mounting groove from the side of the hinge away from the heating element assembly, and fixes the anti-detachment component to the second rotary positioning component, so that the second rotary positioning component is fixed to the hinge and prevents the second rotary positioning component from detaching from the hinge.

[0018] A further feature of this invention is that the anti-detachment component has an anti-detachment protrusion, and when the anti-detachment component is installed in the first mounting groove, the anti-detachment protrusion cooperates with the first mounting groove to prevent detachment.

[0019] By adopting the above technical solution, the anti-detachment protrusion prevents the anti-detachment component from detaching from the first mounting groove.

[0020] A further feature of this invention is that the anti-detachment component has a limiting protrusion, and the hinge portion has a corresponding stop block, with the limiting protrusion and the stop block engaging in a stop-and-stop cooperation.

[0021] By adopting the above technical solution, when the heating element assembly rotates to the horizontal position, the second rotating positioning component drives the anti-detachment component to rotate. At this time, the limiting protrusion on the anti-detachment component abuts against the stop block to prevent the heating element assembly from being damaged due to excessive rotation and improve the durability of the equipment.

[0041] The present invention will be further described below with reference to the accompanying drawings.

[0042] A type of rotatable and adjustable heater, such as Figure 1-4 As shown, the device includes a base body 1 and a heating element assembly 2. The base body 1 is provided with a hinge part 3. The heating element assembly 2 is rotatably engaged with the hinge part 3 through a rotary positioning structure 5. The rotary positioning structure 5 includes a first rotary positioning member 51, a second rotary positioning member 52, and a spring 53. When the user rotates the heating element assembly 2, the heating element assembly 2 drives the second rotary positioning member 52 to rotate. The second toothed engagement part 521 pushes the first toothed engagement part 511 to move away from the heating element assembly 2. At this time, the spring 53 is compressed. After the rotation is completed, the first rotary positioning member 51 is reset under the action of the spring force of the spring 53, so that the first rotary positioning member 51 abuts against the second rotary positioning member 52. At this time, the first toothed engagement part 511 on the first rotary positioning member 51 and the second toothed engagement part 521 on the second rotary positioning member 52 engage to prevent rotation, so that the heating element assembly 2 is fixed at the current angle, which facilitates the adjustment of the horizontal angle of the heater and increases the horizontal coverage area when the heater is heating.

[0043] like Figure 2 As shown, in this embodiment, the second rotating positioning member 52 is fixed in the middle of the heating body assembly 2. When the user rotates the heating body assembly 2, the heating body assembly 2 rotates around the middle, so that the center of gravity is kept in the center during the rotation, which is not easy to be eccentric and thus cause the heater to tip over, thereby improving the stability of the heater when in use. In addition, a support part 21 is provided at the bottom of the heating body assembly 2. The support part 21 is provided on the side facing the base body 1. When the heating body assembly 2 is in a vertical state, the heating body assembly 2 is positioned and supported by the support part 21 and the connecting rod 4, thereby improving the stability of the heating body assembly 2 in the vertical state.

[0044] like Figure 7 As shown, in this embodiment, the second rotary positioning member 52 has a positioning post 522 circumferentially arranged on the side near the heating element assembly 2, and an annular slot 523 is opened on the side of the second rotary positioning member 52 near the first rotary positioning member 51. When the heating element assembly 2 is installed on the base body 1, the positioning post 522 is inserted into the positioning groove 22 provided on the heating element assembly 2. The second rotary positioning member 52 is positioned and engaged with the annular insertion part 31 through the annular slot 523, and the second rotary positioning member 52 can rotate along the opening direction of the annular slot 523, which improves the installation accuracy of the second rotary positioning member 52. In addition, the hinge part 3 is provided with a second mounting groove 35 for the spring 53 and the first rotary positioning member 51 to be inserted. The second mounting groove 35 is provided with a positioning protrusion 351, and the first rotary positioning member 51 is provided with a corresponding positioning recess 512. When the first rotary positioning member 51 is installed, the positioning protrusion 351 is inserted into the positioning recess 512, which improves the installation accuracy and ease of installation of the second rotary assembly. At the same time, it restricts the circumferential rotation of the first rotary positioning member 51, so that when the second rotary positioning member 52 rotates, the first rotary positioning member 51 only produces axial displacement and will not rotate with the second rotary positioning member 52.

[0045] like Figure 7 , 8 As shown in Figure 9, in this embodiment, the hinge portion 3 has a first mounting groove 32, and an anti-detachment member 33 is inserted into the mounting groove. The anti-detachment member 33 has an anti-detachment protrusion 331. When the user installs the device, the anti-detachment member 33 is inserted into the first mounting groove 32 from the side of the hinge portion 3 away from the heating body assembly 2, and the anti-detachment member 33 is fixedly connected to the second rotation positioning member 52, so that the second rotation positioning member 52 is fixed to the hinge portion 3, preventing the second rotation positioning member 52 from detaching from the hinge portion 3. In addition, the anti-detachment member 33 has a limiting protrusion 332, and the hinge portion 3 has a corresponding stop block 34. When the heating body assembly 2 rotates to the horizontal position, the second rotation positioning member 52 drives the anti-detachment member 33 to rotate. At this time, the limiting protrusion 332 on the anti-detachment member 33 abuts against the stop block 34, preventing the heating body assembly 2 from being damaged due to excessive rotation and improving the durability of the device.

[0046] like Figure 10 As shown, in this embodiment, the hinge part 3 is detachably connected to a rear cover 36. The side of the rear cover 36 near the hinge part 3 is provided with a buckle 361. The hinge part 3 is provided with a corresponding slot 37. The slot 37 and the buckle 361 engage with each other, which facilitates disassembly by the user and can protect the internal structure of the hinge part 3 through the rear cover 36, thereby improving the durability of the device.

[0047] The basic working principle of this utility model is as follows: A rotary positioning structure 5 is provided between the heating body assembly 2 and the hinge part 3. When the heating body assembly 2 rotates, the second rotary positioning member 52 rotates and compresses the spring 53 at the same time, so that the first toothed mating part 511 and the second toothed mating part 521 are misaligned. When the rotation reaches the required angle, the first rotary positioning member 51 is reset under the elastic force of the spring 53. At this time, the first toothed mating part 511 and the second toothed mating part 521 engage to stop rotation, thereby fixing the angle of the heating body assembly 2.

[0048] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
