Description

Technical Field

[0001] This utility model relates to the field of temperature limiter technology, and in particular to an adjustable DC high-current temperature controller with magnetic blowout arc extinguishing function. Background Technology

[0002] Existing gas thermostats primarily rely on the contact state of the contacts in their conductive structure for temperature control. When the contacts are in close contact, the entire gas circuit operates normally, allowing gas to flow smoothly and meeting the user's heating or cooking needs. Conversely, when the contacts are not in contact, the entire gas circuit automatically disconnects, effectively preventing potential safety hazards caused by excessive temperature.

[0003] However, this traditional contact-type conduction structure has several significant drawbacks in practical applications. First, at the instant of contact opening or closing, a strong electric arc is often generated due to the instantaneous change in current. The high temperature and high energy of the arc not only cause severe ablation and damage to the contact surface, leading to a gradual decrease in the conductivity of the contacts, but also cause adhesion or jamming between the contacts, further affecting the stability and reliability of the temperature controller.

[0004] Secondly, the temperature threshold of thermostats is usually set to a fixed value, and cannot be adjusted according to the user's specific needs or changes in the external environment. This design limitation makes the application scenarios of thermostats very limited, and cannot meet the temperature control needs of different users in different environments. For example, in cold winters, users may want gas water heaters to provide higher water temperatures, but this requirement cannot be met under the current thermostat design.

[0005] Therefore, this contact-type conduction structure greatly limits the service life and practicality of gas thermostats. Utility Model Content

[0006] The purpose of this invention is to propose an adjustable DC high-current temperature controller with magnetic blowout arc extinguishing function, which can effectively reduce the generation of electric arc when the contacts inside the temperature controller are disconnected or reconnected, reduce damage to the contacts, and also develop an adjustable temperature threshold function to meet the temperature control needs of different users in different environments.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0021] One end of the positioning piece is suspended and mounted on the lower surface of the housing by the positioning bolt, and the other end of the positioning piece is located below the end of the movable contact piece with the movable contact point.

[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0052] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] like Figure 1-4 As shown, an adjustable DC high-current temperature controller with magnetic blowout arc extinguishing function includes a base 1, a housing 2 and a mounting shell 3, wherein the housing 2 and the mounting shell 3 are fitted onto the base 1.

[0054] A first terminal 4 and a second terminal 5 are mounted on the base 1. One end of the first terminal 4 and the second terminal 5 extends out of the base 1, and the other end of the first terminal 4 and the second terminal 5 is located inside the base 1. The other ends of the first terminal 4 and the second terminal 5 are connected by a conductive component 6, which is located below the first terminal 4 and the second terminal 5.

[0055] The mounting shell 3 is located close to the conductive component 6, and the mounting shell 3 has a mounting groove in which a magnet 7 is installed.

[0056] An adjustment component 8 is installed through the outer shell 2, and a hydraulic power component 9 and a connecting component 10 are installed at the bottom end of the adjustment component 8.

[0057] One end of the connecting component 10 is abutted against the lower part of the conducting component 6, and the other end of the connecting component 10 is located below the hydraulic power component 9. There is an adjustment gap between the connecting component 10 and the hydraulic power component 9. The adjustment component 8 is used to drive the hydraulic power component 9 to move up and down to adjust the size of the adjustment gap.

[0058] like Figure 1-4 As shown, the working principle of this utility model is as follows:

[0059] First, connect the first terminal 4 and the second terminal 5 to the DC switching circuit of the external protected device, and install the temperature sensing end of the liquid expansion power assembly 9 on the part of the external protected device to be tested.

[0060] When the temperature of the part to be tested reaches the boiling point of the liquid inside the liquid expansion power assembly 9, the liquid will begin to expand, causing the gap between the liquid expansion power assembly 9 and the connecting assembly 10 to gradually decrease. When the liquid expansion power assembly 9 and the connecting assembly 10 are in close contact, the liquid expansion power assembly 9 will press down the connecting assembly 10, releasing the abutment effect on the conductive assembly 6, thereby disconnecting the connection between the first terminal 4 and the second terminal 5 that were originally connected through the conductive assembly 6, thus achieving overheat protection for the protected device.

[0061] Since both the first terminal 4 and the second terminal 5 generate electric arcs during disconnection or reconnection, a mounting housing 3 with a magnet 7 is placed close to the conductive assembly 6 to protect the first terminal 4 and the second terminal 5 from damage caused by the electric arcs. The magnet 7 generates an arc-extinguishing magnetic field, which strongly blows the electric arcs generated by the first terminal 4 and the second terminal 5 during disconnection or reconnection, thereby changing the arc gap and the duration of the arc burning, and finally extinguishing the arc, completing the arc extinguishing process.

[0062] In addition, an adjustment component 8 is provided, which can move the hydraulic power component 9 up and down to adjust the adjustment distance between the hydraulic power component 9 and the connecting component 10, thereby adjusting the temperature control range of the thermostat.

[0063] In summary, this utility model has the following beneficial effects:

[0064] 1. Enhanced Safety: The magnetic blowout arc extinguishing function effectively prevents damage caused by electric arcs during the disconnection or reconnection of the first terminal 4 and the second terminal 5, extending the service life of the thermostat and the protected devices. Simultaneously, the thermostat accurately responds to temperature changes in the protected devices, promptly disconnecting the circuit and effectively preventing fires and other safety accidents caused by overheating.

[0065] 2. Enhanced adjustability: The temperature controller can flexibly adjust the temperature control range through the adjustment component 8 to adapt to the protection needs under different temperature environments.

[0066] 3. Easy to maintain and operate: The thermostat has a reasonable structural design, making it easy to disassemble and install, and facilitating daily maintenance and replacement. At the same time, the adjustment component 8 makes adjusting the temperature control range simple and quick, without the need for complicated operations.

[0067] To further explain, the conductive component 6 includes a moving contact 61, a moving contact 62, and a stationary contact 63;

[0068] One end of the movable contact 61 is fixedly connected to one end of the second terminal 5, and the movable contact 62 is installed on the upper surface of the other end of the movable contact 61. The stationary contact 63 is installed on one end of the first terminal 4, and the movable contact 62 and the stationary contact 63 are arranged opposite to each other.

[0069] The connecting assembly 10 includes an abutment block 100, a connecting spring 101, and a fixing bolt 102;

[0070] One end of the connecting spring piece 101 is provided with a connecting through hole 103, and the fixing bolt 102 passes through the connecting through hole 103 to suspend the connecting spring piece 101 on the lower surface of the outer shell 2.

[0071] The middle part of the connecting spring 101 is located below the hydraulic power assembly 9;

[0072] The other end of the connecting spring 101 is equipped with the abutment block 100, and the upper end of the abutment block 100 abuts against the lower surface of the middle part of the movable contact piece 61;

[0073] The abutment block 100 switches between a first position state and a second position state under the action of the connecting spring 101. In the first position state, the abutment block 100 moves closer to the moving contact piece 61 and applies pressure to the moving contact piece 61, so that the moving contact 62 and the stationary contact 63 are in contact and connected. In the second position state, the abutment block 100 moves away from the moving contact piece 61, releases the pressure on the moving contact piece 61, so that the moving contact 62 and the stationary contact 63 are separated and a gap is formed.

[0074] like Figure 2-3 As shown, since the connecting spring 101 is suspended on the lower surface of the housing 2 by the fixing bolt 102, when the connecting spring 101 is subjected to the pressure of the hydraulic expansion power assembly 9, the connecting spring 101 can move smoothly under pressure, which allows the abutment block 100 located on it to gradually reduce the pressure on the moving contact 61. As the abutment block 100 gradually reduces the pressure on the moving contact 61, the other end of the moving contact 61, on which the moving contact 62 is installed, will gradually droop downward until the moving contact 62 separates from the stationary contact 63 that was originally connected to one end of the first terminal 4, thereby cutting off the circuit connection between the first terminal 4 and the second terminal 5, and realizing overheat protection for the protected device.

[0075] Furthermore, the conductive assembly 6 also includes a positioning piece 64 and a positioning bolt 65;

[0076] One end of the positioning piece 64 is suspended and mounted on the lower surface of the housing 2 by the positioning bolt 65, and the other end of the positioning piece 64 is located below the end of the movable contact piece 61 with the movable contact point 62.

[0077] like Figure 2-4 As shown, as the abutment block 100 gradually reduces its pressure on the movable contact 61, the other end of the movable contact 61, where the movable contact 62 is mounted, gradually droops downward until the movable contact 62 separates from the stationary contact 63, which was originally connected to one end of the first terminal 4. The other end of the movable contact 61 rests on the positioning plate 64, which is fixedly mounted by the positioning bolt 65, and supports the movable contact 61 to prevent it from drooping excessively.

[0078] To further explain, the adjustment assembly 8 includes a bracket 81, an adjustment seat 82, and an adjustment shaft 83;

[0079] The bracket 81 has a first mounting through hole 810 at its center. The bracket 81 is mounted on the upper surface of the housing 2, and the upper surface of the housing 2 has a second mounting through hole 20 corresponding to the first mounting through hole 810.

[0080] The adjusting female seat 82 is fixedly installed in the second mounting through hole 20. One end of the adjusting shaft 83 passes through the first mounting through hole 810, the second mounting through hole 20 and the adjusting female seat 82 in sequence. The adjusting shaft 83 is threadedly connected to the adjusting female seat 82. The bottom end of the adjusting shaft 83 is fixedly connected to the hydraulic power assembly 9.

[0081] Specifically, such as Figure 1-4 As shown, by rotating the adjusting shaft 83 forward or backward, one end of the adjusting shaft 83 passing through the adjusting female seat 82 moves up and down, thereby driving the hydraulic expansion power assembly 9 connected to the bottom end of the adjusting shaft 83 to move together, realizing precise adjustment of the adjustment distance between the hydraulic expansion power assembly 9 and the connecting assembly 10, thereby changing the operating temperature of the temperature controller and realizing fine control of the temperature control range to meet the temperature protection needs under different application scenarios.

[0082] To further explain, a fixing seat 84 is fitted on the adjusting female seat 82, and two fixing clips 87 extend downward from the fixing seat 84. Two mounting brackets 11 are formed inside the base 1, and the lower ends of the two fixing clips 87 are respectively installed in the two mounting brackets 11.

[0083] A limiting plate 85 and a leaf spring 86 are sleeved on the adjusting shaft 83. The limiting plate 85 and the leaf spring 86 are both located between the fixed seat 84 and the hydraulic power assembly 9. The limiting plate 85 is fixedly connected to the adjusting shaft 83. The two ends of the leaf spring 86 are respectively engaged with the two fixed clamps 87. The limiting plate 85 abuts against the upper surface of the leaf spring 86.

[0084] Specifically, such as Figure 2-4 As shown, the fixed seat 84 is used by two fixed clamps 87 to limit the rotation of the adjusting seat 82 and the leaf spring 86 and to support the leaf spring 86;

[0085] Because the adjusting shaft 83 may slip axially when moving up and down along the adjusting base 82, i.e., it may deviate in the vertical direction, a limiting plate 85 and a leaf spring 86 are designed. When the adjusting shaft 83 moves up and down along the adjusting base 82, the limiting plate 85 rotates along with it, while the leaf spring 86 is fixedly installed between the two fixing clamps 87. When the limiting plate 85 rotates within the leaf spring 86, it not only restricts the axial slippage of the adjusting shaft 83, keeping the adjusting shaft 83 vertically connected to the adjusting base 82, but also, the elastic resistance of the leaf spring 86 during rotation prevents over-adjustment of the adjusting shaft 83.

[0086] To further explain, the liquid expansion power assembly 9 includes a temperature sensing mold 91, a temperature sensing connecting pipe 92, and a temperature sensing probe 93;

[0087] The temperature sensing mold 91 is fixedly installed at the bottom end of the adjusting shaft 83, and the temperature sensing mold 91 is fixedly connected to the temperature sensing probe 93 through the temperature sensing connecting pipe 92.

[0088] Specifically, such as Figure 1-4 As shown, the temperature of the protected device's component is detected by the temperature-sensing probe 93, and then transmitted to the temperature-sensing connecting tube 92. This causes the liquid inside the temperature-sensing diaphragm to expand, deforming the diaphragm. This deformation acts on the connecting assembly 10, ultimately controlling the connection or disconnection of the circuit between the first terminal 4 and the second terminal 5. Utilizing the high sensitivity and good stability of the liquid expansion power assembly 9, the circuit between the first terminal 4 and the second terminal 5 can be quickly disconnected or connected, achieving accurate temperature control.

[0089] To further explain, the connecting spring 101 has a movable through hole 104 in the middle;

[0090] A contact post 94 is installed below the temperature sensing mold box 91. The outer surface of the contact post 94 has a protruding contact part 95. The contact post 94 can movably pass through the movable through hole 104. The contact part 95 abuts against the upper surface of the connecting spring piece 101.

[0091] Specifically, such as Figure 2-4 As shown, a stop post 94 is installed below the temperature sensing mold 91. The outer surface of the stop post 94 is specially designed with a protruding stop portion 95. As the temperature sensing mold 91 moves downward, the stop post 94 passes through the movable through hole 104 opened in the middle of the connecting spring 101 and moves along the direction of its movable through hole 104. It then uses its stop portion 95 to tightly abut against the upper surface of the connecting spring 101, so that the connecting spring 101 can move smoothly when pressed.

[0092] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
