Description

TECHNICAL FIELD

[0001] The present application relates to a temperature controller, more particularly, to a hydraulic temperature controller with protection. BACKGROUND

[0002] The temperature controller switch senses the temperature change of the external environment by means of the temperature sensing component. When the temperature sensing component detects fluctuations in the external temperature (such as an increase in temperature), it will produce a corresponding expansion deformation, and then this deformation will drive the spring sheet inside the temperature controller to act, thereby achieving the on-off adjustment of the temperature controller contacts.

[0003] The hydraulic temperature controller achieves temperature sensing through the expansion of the liquid. The expansion of the liquid in the temperature sensing capsule is transmitted to the temperature sensing diaphragm box through the capillary tube. The expansion of the liquid drives the temperature sensing diaphragm box to produce a corresponding expansion, thereby achieving control of the temperature controller. When the temperature rises to the temperature limit, the expansion of the liquid reaches a certain limit, and the temperature sensing diaphragm box also reaches a certain expansion amount. The temperature sensing diaphragm box can drive the elastic sheet assembly to move, thereby disconnecting the temperature controller. When the temperature sensing temperature decreases, the liquid will release pressure, and the temperature sensing diaphragm box will contract accordingly, thereby allowing the temperature controller to be connected. That is, the existing hydraulic temperature controller is usually disconnected when the temperature reaches the upper limit, and the corresponding heating component is connected to heat when the temperature is below the upper limit.

[0004] However, when the temperature sensing liquid circuit of the hydraulic temperature controller leaks, such as the temperature sensing capsule, the capillary tube, or the connection of the capillary tube, the temperature sensing capsule and the temperature sensing diaphragm box will lose the original internal pressure due to the release of pressure, which will cause the temperature controller to fail to achieve temperature sensing and disconnection, resulting in a dangerous situation where the temperature controller switch is always in the connected state.

[0005] Therefore, a new solution is needed to solve this problem. SUMMARY

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] Embodiment one

[0031] The embodiment discloses a hydraulic temperature controller with protection, referring to Figures 1-3 , which comprises a supporting shell 1, a contact 2, a contact 3, an elastic sheet assembly 4, a supporting block 5, an adjusting screw 6 and a temperature sensing film box 7. The contact 2 and the contact 3 are fixedly installed on the supporting shell 1, serving as two power connection ends of the temperature controller.

[0032] Referring to Figure 2 , the elastic sheet assembly 4 comprises a supporting sheet 41, a movable contact 42, a temperature regulating elastic sheet 43 and an arc-shaped elastic sheet 44. The first end 411 of the supporting sheet 41 is welded and fixed to the contact 2, so that the elastic sheet assembly 4 can be in communication with the contact 2. The second end 412 of the supporting sheet 41 is supported by the supporting block 5, so that the supporting sheet 41 serves as the overall support of the elastic sheet assembly 4.

[0033] The movable contact 42 is located between the supporting sheet 41 and the contact 3. The connecting end 421 of the movable contact 42 is fixed to the second end 412 of the supporting sheet 41, and the movable end 422 of the movable contact 42 extends to the outside of the contact 2. The fixed contact 21 is riveted and fixed to the contact 2, and the movable contact 423 is riveted and fixed to the movable end 422 of the movable contact 42. When the movable contact 423 is close to the fixed contact 21, the movable contact 423 and the fixed contact 21 are in contact, so that the temperature controller is turned on. When the movable contact 423 is away from the fixed contact 21, the movable contact 423 and the fixed contact 21 are disconnected, so that the temperature controller is turned off, and the on-off switching is realized.

[0034] One end of the temperature-adjusting elastic sheet 43 is connected to the first end 411 of the supporting sheet 41, and the other end is elastically and obliquely bent away from the elastic sheet assembly 4. The temperature-adjusting elastic sheet 43 has a certain elasticity. One end of the arc-shaped elastic sheet 44 is connected to the movable end 422 of the movable contact sheet 42, and the other end is elastically abutted against the temperature-adjusting elastic sheet 43. The arc-shaped elastic sheet 44 has a downwardly protruding arc-shaped structure, and the left end extends toward the upper side and abuts against the temperature-adjusting elastic sheet 43, so that the temperature-adjusting elastic sheet 43 and the arc-shaped elastic sheet 44 are connected to each other.

[0035] Referring to Figure 1 As shown in the figure, the adjusting screw 6 is threadedly connected to the supporting shell 1 and located on the upper side of the elastic sheet assembly 4. The temperature-sensitive diaphragm box 7 is mounted on the end of the adjusting screw 6 and can abut against the side of the temperature-adjusting elastic sheet 43 away from the movable contact sheet 42.

[0036] Specifically, the temperature-sensitive diaphragm box 7 is fixedly connected with a connecting column 71 on one side and an insulating column 72 on the other side. The connecting column 71 is fixedly connected to the end of the adjusting screw 6, and an inner hole is formed in the end of the adjusting screw 6, and the connecting column 71 is inserted into the end of the adjusting screw 6 and is adhesively fixed. The insulating column 72 elastically abuts against the temperature-adjusting elastic sheet 43 in the direction of the movable contact sheet 42, and the temperature-adjusting elastic sheet 43 of the elastic sheet assembly 4 is adjusted by the insulating column 72, so that the temperature-adjusting elastic sheet 43 can be adjusted.

[0037] Referring to Figure 1 As shown in the figure, the hydraulic temperature controller in the embodiment further comprises a temperature-sensitive capsule 8 which is communicated with the temperature-sensitive diaphragm box 7 through a capillary tube 81. The temperature-sensitive capsule 8 is installed near the heating wire of the electric appliance, so that the heating degree can be detected. When the temperature-sensitive capsule 8 detects that the temperature rises, the liquid in the temperature-sensitive capsule 8 will expand, and the pressure will rise, so that the temperature-sensitive diaphragm box 7 on both sides can expand, and the arc-shaped elastic sheet 44 can be pressed, so that the left end of the arc-shaped elastic sheet 44 is pressed downward, and the right end rises, and the movable contact sheet 42 can be pressed upward, so that the movable contact 423 of the right end of the movable contact sheet 42 can be deflected upward, and when the temperature-sensitive capsule 8 detects that the temperature further rises to the temperature control limit, the movable contact 423 of the movable contact sheet 42 can be separated from the fixed contact 21 of the contact 2, so that the temperature controller is disconnected.

[0038] The adjusting screw 6 is adjusted by screwing, so that the position of the adjusting screw 6 and the temperature-sensitive diaphragm box 7 can be adjusted in advance, and the force of the temperature-adjusting elastic sheet 43 can be adjusted in advance, the temperature control limit of the temperature controller can be adjusted, and the temperature control limit of the temperature controller can be adjusted.

[0039] Referring to Figures 1-3 As shown in the figure, the supporting block 5 is abutted against and supported on the side of the supporting sheet 41 away from the adjusting screw 6, and referring to Figure 1The support block 5 is located at the lower side of the support sheet 41 and can press against the support at the lower side of the support sheet 41. A support cylinder 51 is fixedly connected in the support shell 1 and can serve as the support for the support block 5.

[0040] A stepped support surface 511 is formed on the inner periphery of the support cylinder 51 and faces the support sheet 41. When installed, part of the support block 5 is embedded in the inner periphery of the support cylinder 51, which can limit the support block 5. The lower end of the support block 5 can abut against the stepped support surface 511, which can support the support block 5.

[0041] A support screw 52 is threadedly connected to the inner periphery of the support cylinder 51. A spring 53 is elastically pressed between the upper end of the support screw 52 and the support block 5. Part of the spring 53 is embedded in the end surface of the support block 5. When installed, the spring 53 and the stepped support surface 511 jointly apply pressure to the support block 5 and jointly support the support block 5.

[0042] The support screw 52 is adjusted by screwing, which can apply pressure upward to the spring 53 and further apply pressure upward to the support block 5.

[0043] Referring to Figure 1 In this embodiment, the hydraulic temperature controller further includes a temperature-sensing diaphragm box 9. One side (i.e., the upper side) of the temperature-sensing diaphragm box 9 is mounted to the support shell 1, which can support the temperature-sensing diaphragm box 9. The other side (i.e., the lower side) of the temperature-sensing diaphragm box 9 can apply a pressing force to the support sheet 41 in the direction of the support block 5. The second end 412 of the support sheet 41 is limited by the support block 5 and the temperature-sensing diaphragm box 9 on both sides.

[0044] The lower side of the second end 412 of the support sheet 41 is jointly supported by the spring 53 and the stepped support surface 511, and the upper side is pressed downward by the temperature-sensing diaphragm box 9, which can jointly maintain the support sheet 41 in a relatively stable state.

[0045] Further, the force is transmitted between the temperature-sensing diaphragm box 9 and the second end 412 of the support sheet 41 through a linkage rod 10. Referring to Figure 1 In this embodiment, the hydraulic temperature controller further includes a linkage rod 10. The linkage rod 10 is located on the side of the support sheet 41 away from the support block 5. The linkage rod 10 has a hinged end 101 and a pressing end 102. The hinged end 101 is located on the left side and is rotationally connected to the support shell 1. The pressing end 102 extends to the right and can press against the second end 412 of the support sheet 41 on the side (i.e., the upper side) away from the support block 5.

[0046] Further, the temperature-sensitive membrane box two 9 is located on the side of the linkage lever 10 away from the support sheet 41, and is mounted on one side of the support shell 1 and pressed against the linkage lever 10 on the other side. The pressing position of the temperature-sensitive membrane box two 9 is located near the hinged end 101 of the linkage lever 10, and the distance between the pressing position of the temperature-sensitive membrane box two 9 and the linkage lever 10 is about 1 / 3-1 / 2 of the length of the linkage lever 10, so as to form a lever structure. The temperature-sensitive membrane box two 9 can form a small floating deflection action, and the deflection amplitude of the linkage lever 10 at the pressing end 102 can be amplified, thereby increasing the deflection floating of the second end 412 of the support sheet 41.

[0047] Further, the temperature-sensitive membrane box two 9 is in communication with the capillary tube 81. The temperature-sensitive membrane box two 9 can also expand and contract due to the expansion and contraction of the liquid, thereby generating an expansion and contraction action.

[0048] When the temperature-sensitive capsule 8 detects a temperature rise, the liquid in the temperature-sensitive capsule 8 will expand, the pressure will rise, and both the temperature-sensitive membrane box one 7 and the temperature-sensitive membrane box two 9 will expand by a certain amount. The expansion and contraction action of the temperature-sensitive membrane box one 7 will drive the temperature-regulating elastic sheet 43 to act, thereby driving the elastic sheet assembly 4 to act, and enabling the movable contact 423 of the elastic sheet assembly 4 to switch with the fixed contact 21.

[0049] At the same time, the temperature-sensitive membrane box two 9 can also expand by a certain amount. After the temperature-sensitive membrane box two 9 expands, the linkage lever 10 can be further pressed down, and the pressing end 102 of the linkage lever 10, the second end 412 of the support sheet 41, the support block 5 and the stepped support surface 511 are limited by each other, so as to keep the position of the second end 412 of the support sheet 41 stable and not affected by the downward pressure of the temperature-sensitive membrane box two 9. When the liquid pressure line of the temperature-sensitive capsule 8, the capillary tube 81, the temperature-sensitive membrane box one 7 and the temperature-sensitive membrane box two 9 leaks (for example, the temperature-sensitive capsule 8 detects an excessively high temperature and leaks, or the pipeline of the temperature-sensitive capsule 8 and the capillary tube 81 is damaged and leaks), the liquid pressure in the pipeline will leak, the original pressure will be released, and the pressure in the temperature-sensitive membrane box two 9 will disappear and be restored. After the pressure in the temperature-sensitive membrane box two 9 disappears, the downward pressure of the lower side of the temperature-sensitive membrane box two 9 and the linkage lever 10 will decrease, the linkage lever 10 can be slightly upwardly deflected, the downward pressure of the pressing end 102 of the linkage lever 10 on the second end 412 of the support sheet 41 cannot overcome the elastic force of the spring 53, thereby enabling the second end 412 of the support sheet 41 to be upwardly deflected, enabling the support sheet 41 to drive the movable contact sheet 42 to be upwardly deflected, thereby enabling the movable contact 423 of the movable contact sheet 42 to move up and down, enabling the movable contact 423 to be separated from the fixed contact 21, and enabling the hydraulic temperature controller to be disconnected.

[0050] By providing the temperature-sensitive membrane box 29, it can play a protective role when a leak occurs in the hydraulic pipeline, and can separate and disconnect the moving contact 423 and the fixed contact 21 of the hydraulic thermostat, thereby realizing disconnection protection of the hydraulic thermostat.

[0051] Example 2

[0052] This embodiment discloses a hydraulic temperature controller with protection. Figure 4 Provide detailed explanation.

[0053] Further, refer to Figure 4 As shown, the second thermosensitive membrane box 9 and the capillary tube 81 are connected via a connecting piece 91. The connecting piece 91 has a connecting inner cavity formed therein. The connecting piece 91 is connected to a first connecting capillary tube 911 and a second connecting capillary tube 912. The first connecting capillary tube 911 is connected to the second thermosensitive membrane box 9, and the second connecting capillary tube 912 is connected to the capillary tube 81. This connects the second thermosensitive membrane box 9 with the capillary tube 81, connecting the second thermosensitive membrane box 9 to the hydraulic flow path. The second thermosensitive membrane box 9 can be affected by the hydraulic pressure and produce a corresponding deformation.

[0054] Connecting piece 91 is cylindrical in structure, with an inner cavity of connecting piece 91 also having a cylindrical structure. A piston 92 is mounted inside connecting piece 91, and a connection port 94 is provided at the upper end of connecting piece 91. Connecting piece 91's lower portion and side surfaces are connected to connecting capillary tube 1 911 and connecting capillary tube 2 912, enabling communication with the inner cavity of connecting piece 91.

[0055] An internal thread is formed on the connection port 94, and an external thread is formed on the screw member 93. The screw member 93 is threadedly connected to the connection port 94. The inner circumference of the connection port 94 is threadedly connected to the screw member 93. The end of the screw member 93 extends into the inner cavity of the connecting member 91 and connects to the piston member 92. By adjusting the screw member 93, the piston member 92 can be adjusted, thereby adjusting the pressure in the inner cavity of the connecting member 91, and thus the initial pressure inside the thermosensitive membrane box 2 9 and the thermosensitive membrane box 1 7 can be adjusted accordingly. By adjusting the internal pressure of the thermosensitive membrane box 2 9, the thermosensitive membrane box 2 9 has an initial thickness. After the hydraulic pipeline is damaged and leaks, the internal cavity of the thermosensitive membrane box 2 9 will be depressurized, allowing the thickness of the thermosensitive membrane box 2 9 to be compressed and restored. Its thickness will become thinner, reducing the limiting effect on the linkage rod 10. The linkage rod 10 can swing up and down, causing the support piece 41 to move upward, and the movable contact piece 42 to deflect upward, causing the thermostat to disconnect.

[0056] In addition, before the debugging operation, the inner pressure of the temperature sensing film box 2 can be pre-adjusted by adjusting the screw rod 93, and the compression amount of the spring 53 can be pre-adjusted by cooperating with the supporting screw rod 52, then the whole temperature controller is adjusted and calibrated, after the adjustment is completed, the connecting port 94 is sealed and fixed by welding a seal between the screw rod 93 and the connecting port 94.

[0057] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-described embodiments. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
