[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0028] See also Figure 1 , Figure 2 as well as Figure 3 The utility model discloses a conveniently adjustable temperature controller, including a mounting body 10, a static contact piece 20, a moving contact piece 30 and an adjusting component. The mounting body 10 is provided with a temperature sensing component, and the specific temperature sensing component includes a temperature sensing element and a push rod 42, and the temperature sensing element is connected to the push rod 42, and the push rod 42 moves after the temperature sensing element senses temperature changes.
[0029] The above-mentioned stationary contact piece 20 and the moving contact piece 30 are both installed on the installation body 10, and the stationary contact piece 20 and the moving contact piece 30 are distributed at intervals, and the stationary contact piece 20 is electrically connected to the first terminal 60, and the moving contact piece 30 is electrically connected to the second terminal 70. The moving contact piece 30 is connected to the push rod 42, and the moving contact piece 30 moves close to or away from the stationary contact piece 20 during the movement of the push rod 42; the moving contact piece 30 contacts the stationary contact piece 20 after moving close to the stationary contact piece 20; the moving contact piece 30 is used to disconnect from the stationary contact piece 20 after moving away from the stationary contact piece 20;
[0030] The adjustment assembly includes an adjustment rod 51 and an adjustment plate 52. The adjustment rod 51 is rotatably installed on the installation body 10. One end of the adjustment rod 51 is against the moving contact plate 30. The other end of the adjustment rod 51 is connected to the adjustment plate 52. The adjustment plate 52 can drive the adjustment rod 51 to rotate when subjected to external force. The adjustment rod 51 is used to move closer to or away from the moving contact plate 30 when rotating.
[0031] When using the conveniently adjustable thermostat of the utility model, the first terminal 60 and the second terminal 70 can be connected to the circuit respectively. When in use, during normal operation, the moving contact piece 30 and the stationary contact piece 20 are kept in contact, and the circuit is normally connected. When the temperature reaches the set temperature, the temperature sensing element can sense the temperature, deform, and push the push rod 42 upward to drive the moving contact piece 30 connected to the push rod 42 to move upward and disconnect from the stationary contact piece 20, thereby achieving temperature control.
[0032] When realizing temperature control, the installation body 10 of the thermostat can be installed on an electrical device, such as a heater, to control the heating temperature. After the installation body 10 is installed, the temperature sensing element of the thermostat receives the temperature and reaches a suitable temperature, and then pushes the push rod 42 connected thereto to move, driving the moving contact piece 30 away from the static contact piece 20, disconnecting the circuit connection, and realizing accurate temperature control.
[0033] Of course, the thermostat can also be used for overheating temperature control of electrical equipment. That is, when the circuit of the electrical equipment overheats due to an abnormality, when the working circuit overheats abnormally, the temperature sensing element receives the temperature and reaches the appropriate temperature, and then pushes the push rod 42 connected to it to move, driving the moving contact piece 30 away from the static contact piece 20, disconnecting the circuit connection, achieving accurate temperature control, and protecting the electrical equipment.
[0034] It should be noted that, since different devices need to adjust the temperature control range during actual use, the spacing between the moving contact piece 30 and the stationary contact piece 20 needs to be adjusted. If the spacing between the moving contact piece 30 and the stationary contact piece 20 is small, the temperature sensing element can drive the push rod 42 to push the moving contact piece 30 to contact the stationary contact piece 20 when the temperature changes slightly, thereby achieving temperature control. If the spacing between the moving contact piece 30 and the stationary contact piece 20 is large, the temperature sensing element can drive the push rod 42 to push the moving contact piece 30 to contact the stationary contact piece 20 when the temperature changes significantly, thereby achieving temperature control.
[0035] Therefore, in this embodiment, the adjusting rod 51 is provided, and the adjusting rod 51 rotates close to or away from the moving contact piece 30, driving the moving contact piece 30 to be close to or away from the stationary contact piece 20, so that the distance between the two can be adjusted, thereby achieving the adjustment of the temperature control range. The adjustment of the adjusting rod 51 is to apply force to the adjusting piece 52, and the adjusting piece 52 has a larger adjustment surface than the adjusting rod 51, so that it is convenient for the adjusting piece 52 to rotate under force, so that it is easier to drive the adjusting rod 51 to rotate, the adjusting rod 51 rotates smoothly, and the adjustment accuracy of the adjusting rod 51 is better, thereby improving the temperature control adjustment accuracy.
[0036] Furthermore, an operating rod 53 is protruding from the adjusting plate 52, and the operating rod 53 can be extended outside the device to install a knob structure, so that the user can operate the rotation of the adjusting plate 52 outside the device, thereby making the adjustment of the adjusting rod 51 more convenient.
[0037] Furthermore, the above-mentioned adjusting plate 52 is provided with a through hole, and the adjusting rod 51 is inserted into the through hole; the adjusting rod 51 and the inner wall of the through hole are matched with the friction part 511, so that after the adjusting rod 51 and the adjusting plate 52 are assembled, the adjusting rod 51 and the adjusting hole of the adjusting plate 52 are in contact and matched with the friction part 511, thereby increasing the rotational friction between the two, preventing slipping during the adjustment process, and the assembly structure is more stable.
[0038] Furthermore, a plurality of friction portions 511 are provided, and the plurality of friction portions 511 are spaced apart in the circumferential direction of the adjusting rod 51 and abut against the inner wall of the perforation. It should be noted that the friction portion 511 can be selected as a convex rib or a concave structure in the prior art, which can form a concave-convex structure on the outside of the adjusting rod 51, which is used to cooperate with the concave-convex perforation of the adjusting plate 52 to increase friction, thereby improving assembly stability and rotation stability.
[0039] Of course, the connection between the adjusting piece 52 and the adjusting rod 51 can be fixed by stamping or by welding.
[0040] Furthermore, a first limiting portion may be provided on the installation body 10, and a corresponding second limiting portion may be provided in the adjusting plate 52. The second limiting portion is used to abut against the first limiting portion when the adjusting plate 52 rotates. In this way, the rotation range of the adjusting plate 52 can be limited by the abutment and cooperation between the first limiting portion and the second limiting portion, thereby preventing the adjusting rod 51 from rotating excessively, and making the adjustable range of the temperature control controllable.
[0041] Specifically, a limit plate 11 is protruding from the above-mentioned installation body 10, and a limit groove 54 is provided on the adjustment plate 52, and the limit groove 54 is an arc groove; the limit plate 11 is slidably connected in the limit groove 54, so that during the rotation of the adjustment plate 52, the limit plate 11 can slide along the limit groove 54, and when it slides to abut against the end wall of the limit groove 54, the mutual sliding of the limit plate 11 and the limit groove 54 can be limited, thereby realizing the rotation limit of the adjustment plate 52.
[0042] Based on the above structure, the limiting piece 11 is formed as the first limiting part, and the limiting groove 54 is formed as the second limiting part. Of course, in other cases, the first limiting part and the second limiting part can also be formed as a protruding block structure that cooperates with each other in the rotation direction.
[0043] Furthermore, in order to facilitate the positioning and installation of the adjustment rod 51, a mounting plate 12 may be provided on the installation body 10, and an adjustment hole may be provided on the mounting plate 12. The mounting plate 12 may be located above the movable contact piece 30, so that the adjustment rod 51 is installed on the mounting plate 12, and the adjustment rod 51 may move up and down above the movable contact piece 30. Specifically, the adjustment rod 51 is an adjustment screw, and the adjustment screw is threadedly connected to the adjustment hole. In this way, the adjustment screw can be rotated to drive the adjustment screw to move up and down relative to the adjustment hole thread, so that the adjustment rod 51 is close to or away from the movable contact piece 30, and the temperature control range is adjustable.
[0044] Of course, the adjustment rod 51 can also be rotated by setting a spiral groove on the mounting plate 12 and correspondingly setting a protrusion outside the adjustment rod 51. When the adjustment rod 51 rotates, the protrusion slides along the spiral groove to realize the up and down movement of the adjustment rod 51.
[0045] Furthermore, the temperature sensing element is a temperature sensing metal sheet 41. When the temperature reaches the set temperature, the temperature sensing metal sheet 41 can sense the temperature, deform, and push the push rod 42 to drive the moving contact sheet 30 connected to the push rod 42 to move and disconnect from the static contact sheet 20, thereby achieving temperature control. Specifically, the temperature sensing metal sheet 41 can be selected as a bimetallic sheet in the prior art. The bimetallic sheet has at least two metal layers with different expansion coefficients. Since the thermal expansion coefficients of the metals of each layer are different, when the temperature changes, the deformation of the active layer is greater than that of the passive layer. The bimetallic sheet as a whole will bend and deform toward the passive layer, thereby pushing the push rod 42 to achieve temperature control.
[0046] Of course, the temperature sensing element may also be replaced by a structure such as a liquid expansion temperature sensing component in the prior art (such as a structure of a temperature sensing tube and a membrane box).
[0047] Furthermore, a metal spring 31 is provided on the mounting body 10, one end of the metal spring 31 is connected to the push rod 42, and the other end of the metal spring 31 is provided with a moving contact piece 30. That is to say, when the push rod 42 moves upward, the metal spring 31 can be deformed better, driving the moving contact piece 30 connected thereto to be disconnected from the stationary contact piece 20, and when the moving contact piece 30 is in contact with the stationary contact piece 20, the elastic force provided by the metal spring 31 can also drive the moving contact piece 30 to maintain a contacting conductive state with the stationary contact piece 20, so that the temperature control is more sensitive.
[0048] Furthermore, one end of the temperature-sensitive metal sheet 41 is connected to the installation body 10, and the push rod 42 is connected to the end of the temperature-sensitive metal sheet 41 away from the installation body 10; the width of the temperature-sensitive metal sheet 41 gradually decreases from the end close to the installation body 10 to the end away from the installation body 10. In this way, one end of the temperature-sensitive metal sheet 41 has a larger temperature-sensitive surface, which can receive temperature changes to a greater extent, while the end of the temperature-sensitive metal sheet 41 where the push rod 42 is installed has a smaller width, which facilitates the deformation of the temperature-sensitive metal sheet 41 at this part.
[0049] It should also be noted that the installation body 10 in this embodiment has a ceramic ring assembly, and the ceramic ring assembly includes a first ceramic ring 13, a second ceramic ring 14 and a third ceramic ring 15. The first ceramic ring 13, the second ceramic ring 14 and the third ceramic ring 15 are stacked in sequence from bottom to top, and the first ceramic ring 13, the second ceramic ring 14 and the third ceramic ring 15 can be assembled by bolts and other structures, and the first wiring terminal 60 and the static contact piece 20 are clamped between the first ceramic ring 13 and the second ceramic ring 14, and the moving contact piece 30 and the second wiring terminal 70 are clamped between the second ceramic ring 14 and the third ceramic ring 15, and the temperature-sensitive metal sheet 41 is arranged at the bottom end of the first ceramic ring 13. In this way, the moving contact piece 30 and the second wiring terminal 70, the static contact piece 20 and the first wiring terminal 60 and the temperature-sensitive metal sheet 41 are separated and assembled by the first ceramic ring 13, the second ceramic ring 14 and the third ceramic ring 15, and the insulation effect between them is better.
[0050] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. 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.
