Description

Technical Field

[0001] This utility model belongs to the field of heating element technology, and in particular relates to a heating element with precise temperature control. Background Technology

[0002] To meet the needs of more scenarios, such as quick drying and the coldness of drying hair in winter, hair dryers are equipped with heating elements inside. The heating elements generate heat inside the hair dryer and finally blow out hot air, thus solving the problems of quick drying and the coldness of drying hair in winter.

[0003] However, existing heating elements have a temperature sensing element that is too close to the heat source, causing the sensing element to detect the temperature of the heat source. As a result, the temperature of the air blown out of the blower is much lower than the temperature of the heat source. To solve this technical problem, a heating element with more accurate temperature sensing and control is needed. Utility Model Content

[0004] The purpose of this utility model is: based on the inventor's own practice and combined with actual use, in order to address the shortcomings of the existing technology, the inventor designed a heating element with precise temperature control, so as to solve the technical problems of poor temperature sensing effect, slow response and insufficient response speed of mechanical temperature sensing in the existing technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A heating element with precise temperature control includes multiple heating support plates, the centers of which are staggered. One of the heating support plates is provided with a temperature sensing element, which has a first lead and a second lead. The first lead and the second lead are respectively led out from both ends of the temperature sensing element and are connected to the heating support plate. The first lead and the second lead are respectively set at an angle of 30-70 degrees to the surface of the heating support plate.

[0007] Furthermore, the heating support plate is provided with a receiving groove, which is disposed opposite to the temperature sensing element.

[0008] Furthermore, the length and width dimensions of the receiving groove match the length and width dimensions of the temperature sensing element.

[0009] Furthermore, the receiving groove is disposed on the edge of the heating support plate, and one side of the receiving groove is open, while the other three sides of the receiving groove are closed.

[0010] Furthermore, the receiving groove is located in the middle of the heating support plate, and all four sides of the receiving groove are closed.

[0011] Furthermore, the heating support plate is provided with a first fixing part and a second fixing part, the first lead wire is connected to the first fixing part, and the second lead wire is connected to the second fixing part.

[0012] Furthermore, the second lead includes a straight portion and a bent portion, wherein the bent portion is bent at an angle of 45-180 degrees to the straight portion.

[0013] Furthermore, it also includes a control component, which is electrically connected to the heating support plate and the temperature sensing element respectively. The temperature sensing element senses the temperature of the heating support plate and transmits the signal to the control component. The control component identifies the signal and controls the heating element to heat up or cool down.

[0014] Another objective of this utility model is to provide a temperature sensing element angle clamp, including a clamp body, which is configured to cooperate with the heating element mentioned above. The clamp body includes a head and a tail, which are integrally formed. The head is provided with a slot extending along the length of the clamp body, and the slot has the same thickness as the heating support plate.

[0015] Furthermore, the slot divides the head into a first part and a second part. The first part has an inclined surface, which is set at an angle of 30-70 degrees to the upper surface of the clamp body. The first part is placed between the second lead wire and the heating support plate.

[0016] The beneficial effect of this utility model is that it provides a heating element with precise temperature control, comprising multiple heating support plates arranged in an interlaced pattern. One of the heating support plates is equipped with a temperature sensing element, which has a first lead and a second lead. The first lead and the second lead extend from both ends of the temperature sensing element and are connected to the heating support plate. The first lead and the second lead are respectively set at an angle of 30-70 degrees to the surface of the heating support plate. In this application, the heating element support plate is a mica plate, requiring only the application of mica... When the heating wire on the motherboard is energized, the heating element generates heat. The staggered arrangement of multiple mica plates enhances the structural stability of the heating element. The temperature sensor monitors the temperature generated by the heating element to prevent damage caused by overheating. The temperature sensor is positioned at a certain angle on the heating support plate, with the connection point between the first and second leads and the heating support plate as a reference. This saves space for the heating element, eliminating the need for a separate installation space for the temperature sensor. Furthermore, the suspended position of the temperature sensor allows for better temperature sensing, ensuring that the temperature of the final blown air matches the temperature controlled by the temperature sensor.

[0036] The following is in conjunction with the appendix Figures 1 to 7 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0037] like Figure 1 , 2 As shown in Figure 7, this embodiment discloses a heating element with precise temperature control, including multiple heating support plates 1, the centers of which are staggered. A temperature sensing element 2 is provided on one of the heating support plates 1. The temperature sensing element 2 has a first lead 21 and a second lead 22, which are respectively led out from both ends of the temperature sensing element 2. Both the first lead 21 and the second lead 22 are connected to the heating support plate 1. The first lead 21 and the second lead 22 are respectively set at an angle of 30-70 degrees to the surface of the heating support plate 1.

[0038] Specifically, in this application, the heating support plate 1 is a mica plate. The heating element can generate heat simply by energizing the heating support plate 1. The staggered arrangement of multiple heating support plates 1 can improve the structural stability of the entire heating element. The temperature sensing element 2 is used to monitor the temperature generated by the heating support plate 1 and control the temperature generated by the heating element. The temperature sensing element 2 is set at a certain angle inside the heating element with the connection between the first lead 21 and the second lead 22 and the heating support plate 1 as a reference. On the one hand, it can save the space occupied by the heating element, and there is no need to set up a separate installation space for the temperature sensing element 2. On the other hand, the temperature sensing element 2 is suspended in the heating support plate 1, which can better sense the temperature of the heating element and make the temperature of the finally blown air consistent with the temperature controlled by the temperature sensing element 2.

[0039] Normally, the temperature sensing element 2 is attached to the heating support plate 1. This means that one side of the temperature sensing element 2 cannot sense the temperature of the heating element due to the obstruction of the heating support plate 1, resulting in inaccurate temperature control. However, in this utility model, the temperature sensing element 2 is suspended, allowing it to sense the temperature of the heating element from 360 degrees, making the air blown towards the user more comfortable and ensuring that the temperature is neither too high nor too low.

[0040] The first lead 21 and the second lead 22 are respectively set at angles of 30 degrees, 40 degrees, 50 degrees, 60 degrees and 70 degrees to the surface of the heating support plate 1. Specifically, the first lead 21 and the second lead 22 are respectively set at an angle of 50 degrees to the surface of the heating support plate 1.

[0041] like Figure 2 As shown, in this embodiment, the heating support plate 1 is provided with a receiving groove 11, which is disposed opposite to the temperature sensing element 2.

[0042] Specifically, when installing the temperature sensing element 2, the body of the temperature sensing element 2 is first placed in the receiving groove 11, and the temperature sensing element 2 is initially positioned by the receiving groove 11. The first lead 21 of the temperature sensing element 2 is connected to the heating support plate 1, and finally the second lead 22 is connected to the heating support plate 1. The setting of the receiving groove 11 can position the temperature sensing element 2 and ensure the consistency of the installation of the temperature sensing element 2.

[0043] like Figure 2 As shown, in this embodiment, the length and width dimensions of the receiving groove 11 match the length and width dimensions of the temperature sensing element 2.

[0044] Specifically, the length and width of the receiving groove 11 are matched with the temperature sensing element 2. The receiving groove 11 further restricts the temperature sensing element 2 in both the horizontal and vertical directions, preventing the temperature sensing element 2 from moving in the receiving groove 11. It further limits the position of the temperature sensing element 2. When mass-producing heating elements, it can ensure that the position of the temperature sensing element 2 of each produced heating element is consistent. At the same time, limiting the position of the temperature sensing element 2 also ensures that the temperature sensing element 2 reaches the specified angle when the angle of the temperature sensing element 2 is adjusted by the fixture body 3.

[0045] like Figure 2 As shown, in this embodiment, the receiving groove 11 is disposed on the edge of the heating support plate 1, and one side of the receiving groove 11 is open, while the other three sides of the receiving groove 11 are closed.

[0046] like Figure 7 As shown, in this embodiment, the heating support plate 1 is provided with a first fixing part 12 and a second fixing part 13, the first lead wire 21 is connected to the first fixing part 12, and the second lead wire 22 is connected to the second fixing part 13.

[0047] Specifically, the first fixing part 12 and the second fixing part 13 are used to fix the entire temperature sensing element 2. First, the temperature sensing element 2 is placed in the receiving cavity to fix its position. Then, the first lead wire 21 is straightened and fixedly connected to the first fixing part 12. The second fixing part 13 is then connected to the first fixing part 12. The first lead wire 21 and the second lead wire 22 are connected to the heating support plate 1 to fix the position of the entire temperature sensing element 2 and prevent the position of the temperature sensing element 2 from shifting.

[0048] like Figure 2 As shown in this embodiment, the second lead 22 includes a straight portion 221 and a bent portion 222, with the bent portion 222 bent at an angle of 45-180 degrees to the straight portion 221.

[0049] Specifically, the bent portion 222 and the straight portion 221 are integrally formed. In this embodiment, the bent portion 222 and the straight portion 221 are at angles of 45 degrees, 50 degrees, 55 degrees, 60 degrees, ... 180 degrees. The specific angle between the bent portion 222 and the straight portion 221 is 90 degrees. After the temperature sensing element 2 is installed, the connection between the straight portion 221 and the bent portion 222 is topped by the clamp body 3, so that the temperature sensing element 2 has a certain angle. After the temperature sensing element 2 is deformed by the top, the first lead wire 21 and the second lead wire 22 are the same as those of the heating support plate 1, which further ensures the consistency and temperature sensing ability of the temperature sensing element 2 after deformation.

[0050] In this embodiment, a control component is also included. The control component is electrically connected to the heating support plate 1 and the temperature sensing component 2 respectively. The temperature sensing component 2 senses the temperature of the heating support plate 1 and transmits the signal to the control component. The control component identifies the signal and controls the heating component to heat up or cool down.

[0051] Specifically, the control component is connected to the first fixing part 12 and the second fixing part 13 respectively, so that the control component is connected to the heating support plate 1 and also to the temperature sensing element 2. The control component adjusts the heating power of the heating element through the feedback signal transmitted by the temperature sensing element 2.

[0052] Example 2

[0053] The difference between this embodiment and Embodiment 1 is that the receiving groove 11 is located in the middle of the heating support plate 1, and all four sides of the receiving groove 11 are closed sides (not shown in the figure).

[0054] The other structures are the same as in Embodiment 1, and will not be described in detail in this embodiment.

[0055] Example 3

[0056] like Figure 3 , 4 As shown in Figure 5, this embodiment also provides an angle clamp for the temperature sensing element 2, including a clamp body 3. The clamp body 3 is configured to cooperate with the heating element in Embodiment 1. The clamp body 3 includes a head 31 and a tail 32. The head 31 and the tail 32 are integrally configured, and the head 31 is provided with a slot 311 extending along the length of the clamp body 3. The slot 311 has the same thickness as the heating support plate 1.

[0057] Specifically, the clamp body 3 is used to deform the temperature sensing element 2 to a certain angle. In actual operation, the head 31 operates the heating element, and the tail 32 is used for holding. The same thickness between the slot 311 and the heating support plate 1 can make the slot 311 and the heating support plate 1 more stable when the clamp body 3 operates the temperature sensing element 2, and will not cause vertical displacement, resulting in inconsistent angles after deformation of the temperature sensing element 2. At the same time, the slot 311 also plays a limiting role. When the heating element is engaged in the slot 311, the edge of the heating support plate 1 abuts against the innermost edge of the slot 311. At this time, it means that the clamp body 3 has reached the maximum stroke and the deformation of the temperature sensing element 2 is completed.

[0058] Specifically, the width of the head 31 is smaller than the width of the tail 32.

[0059] like Figure 3As shown, in this embodiment, the slot 311 divides the head 31 into a first part 312 and a second part 313. The first part 312 has a slope 314, which is set at an angle of 30-70 degrees to the upper surface of the clamp body 3. The first part 312 is placed between the second lead wire 22 and the heating support plate 1.

[0060] Specifically, in actual operation, the inclined surface 314 on the first part 312 contacts the second lead 22, and the second lead 22 is lifted by the inclined surface 314. When the second lead 22 is lifted, the angle between the first lead 21 and the heating support plate 1 also changes. This achieves two goals at once. By simply lifting the second lead 22, the first lead 21 and the second lead 22 can be deformed to achieve the required angle. It should be noted that the angle of the inclined surface 314 is 30 degrees, 40 degrees, 50 degrees, 60 degrees, or 70 degrees. Specifically, in this embodiment, the angle of the inclined surface 314 is 50 degrees.

[0061] Example 4

[0062] In this embodiment, unlike in embodiment three, both the first part 312 and the second part 313 have inclined surfaces 314 with the same angle. When the temperature sensing element 2 is operated by the clamp body 3, it is not necessary to distinguish which side is the first part 312. In this embodiment, both the first part 312 and the second part 313 can operate the temperature sensing element 2, which greatly enhances the work efficiency (not shown in the figure).

[0063] The other structures are the same as in Embodiment 3, and will not be described in detail in this embodiment.

[0064] The specific working principle of this application is as follows: First, several heating support plates 1 are assembled in an alternating manner. Then, the temperature sensing element 2 is placed in the receiving groove 11. The first lead wire 21 is fixedly connected to the first fixing part 12. Then, the second lead wire 22 is bent 90 degrees towards the second fixing part 13 and the end of the second lead wire 22 is fixedly connected to the second fixing part 13. At this time, the clamp body 3 is taken out, and the slot 311 is aligned with the heating support plate 1 on which the temperature sensing element 2 is provided. The temperature sensing element 2 is placed in the slot 311, and the first part 312 is placed between the second lead wire 22 and the heating support plate 1. The clamp body 3 is slowly pushed into the temperature sensing element 2 until the edge of the heating support plate 1 abuts the inner edge of the slot 311. At this time, the clamp body 3 can no longer be pushed inward. The temperature sensing element 2 has completed its deformation and reached the specified angle. Then, the clamp body 3 is pulled out. The entire operation is completed.

[0065] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0066] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model.
