Description

Technical Field

[0001] This invention relates to thermostats, and more specifically, to a hydraulic thermostat with protection. Background Technology

[0002] Thermostat switches use temperature-sensing components to detect changes in the ambient temperature. When the temperature-sensing component detects fluctuations in the ambient temperature (such as an increase in temperature), it will expand and deform accordingly. Subsequently, this deformation will cause the internal spring plate of the thermostat to move, thereby regulating the opening and closing of the thermostat contacts.

[0003] Hydraulic thermostats sense temperature through the expansion of a liquid. The expansion of the liquid in the sensing chamber is transmitted to the sensing diaphragm via a capillary tube. The expansion of the liquid causes the sensing diaphragm to expand accordingly, thus controlling the thermostat. When the temperature rises to the temperature limit, the liquid expansion reaches a certain limit, and the sensing diaphragm also expands to a certain extent. The sensing diaphragm then moves the elastic element, thus disconnecting the thermostat. Conversely, when the temperature drops, the liquid depressurizes, and the sensing diaphragm contracts, thus reconnecting the thermostat. In other words, existing hydraulic thermostats typically disconnect when the upper temperature limit is reached and activate the corresponding heating element when the temperature falls below the upper limit.

[0004] However, when a leak occurs in the temperature-sensing fluid circuit of a hydraulic thermostat, such as in the temperature-sensing bladder, capillary tube, or the connection of the capillary tube, the temperature-sensing bladder and temperature-sensing diaphragm will release pressure and lose their original internal pressure. This will cause the thermostat to fail to disconnect due to temperature sensing, resulting in the thermostat switch remaining in the on state, which can easily lead to dangerous situations.

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hydraulic temperature controller with protection.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic thermostat with protection, comprising a support shell, a first contact piece, a second contact piece, an elastic sheet assembly, a support block, an adjusting screw, and a temperature sensing diaphragm box. The first and second contact pieces are respectively fixedly installed on the support shell. The elastic sheet assembly includes a support piece, a movable contact piece, a temperature-adjusting elastic sheet, and an arc-shaped elastic sheet. The first end of the support piece is fixed to the first contact piece, and the second end of the support piece is supported by the support block. The movable contact piece is located between the support piece and the second contact piece. The connecting end of the movable contact piece is fixed to the second end of the support piece, and the movable end of the movable contact piece extends to the outside of the first contact piece and can switch on and off with the first contact piece.

[0008] One end of the temperature-regulating elastic sheet is connected to the first end of the support sheet, and the other end is elastically inclined and bent away from the moving contact sheet. One end of the arc-shaped elastic sheet is connected to the movable end of the moving contact sheet, and the other end is elastically opposed to the temperature-regulating elastic sheet.

[0009] The adjusting screw is threadedly connected to the support shell, and the temperature-sensing diaphragm is installed at the end of the adjusting screw and can abut against the side of the temperature-regulating elastic sheet facing away from the moving contact sheet.

[0010] The present invention is further configured such that a connecting post is fixedly connected to one side of the temperature-sensing film box and an insulating post is fixedly connected to the other side; the connecting post is fixedly connected to the end of the adjusting screw, and the insulating post is elastically abutting against the temperature-regulating elastic sheet in the direction of the moving contact plate.

[0011] The invention is further configured such that the support block presses against the side of the support plate facing away from the adjusting screw; the support shell is fixedly connected to a support cylinder, and a stepped support surface facing the support plate is formed on the inner circumference of the support cylinder; a portion of the support block is embedded in the inner circumference of the support cylinder and abuts against the stepped support surface.

[0012] The invention is further configured such that a support screw is threadedly connected to the inner circumference of the support cylinder, and a spring elastically presses against the end of the support screw and the support block; a portion of the spring is embedded in the end face of the support block; the spring and the stepped support surface together apply pressure to the support block.

[0013] The invention is further configured to include a second temperature-sensing film box, one side of which is installed on the support shell, and the other side is capable of applying a pressing force to the support sheet in the direction of the support block. The second end of the support sheet is limited on both sides by the support block and the second temperature-sensing film box.

[0014] The present invention is further configured to include a linkage rod, which is located on the side of the support piece facing away from the support block. The linkage rod has a hinge end and a pressing end. The hinge end is rotatably connected to the support shell, and the pressing end presses against the side of the support piece facing away from the support block.

[0015] The present invention is further configured such that the second temperature-sensing film is located on the side of the linkage rod facing away from the support plate, one side of the second temperature-sensing film is installed on the support shell, and the other side abuts against the linkage rod.

[0016] The invention is further configured to include a temperature-sensing bladder, which is connected to a temperature-sensing membrane box one via a capillary tube; the temperature-sensing membrane box two is connected to the capillary tube.

[0017] The present invention is further configured such that the second temperature-sensing film box and the capillary tube are connected by a connecting member, the connecting member being connected to a first connecting capillary tube and a second connecting capillary tube, the first connecting capillary tube being connected to the second temperature-sensing film box, and the second connecting capillary tube being connected to the capillary tube.

[0018] The present invention is further configured such that the inner cavity of the connecting member has a cylindrical structure and a piston is installed inside; a connection port is provided at the end of the connecting member, and a screw is threadedly connected to the connection port. The end of the screw extends into the inner cavity of the connecting member and connects with the piston. By adjusting the screw through the thread, the piston can be adjusted, thereby adjusting the pressure inside the connecting member.

[0019] The present invention is further configured such that, after the screw is adjusted, a seal is welded between the screw and the connection port.

[0020] In summary, the present invention has the following beneficial effects:

[0021] By installing the temperature-sensing diaphragm box one onto the adjusting screw, the adjusting screw and the temperature-sensing diaphragm box one can be connected to form a whole. During the temperature adjustment process, the temperature adjustment effect is only formed on one side of the elastic sheet assembly, that is, pressure is applied to the temperature-regulating elastic sheet. The temperature-regulating elastic sheet not only plays the role of temperature adjustment, but also plays the role of temperature sensing and pressure regulation. Both temperature sensing and temperature limit adjustment are applied to the temperature-regulating elastic sheet, which facilitates the adjustment operation.

[0022] The temperature-sensing diaphragm box is connected to the temperature-sensing bag through a capillary tube, which allows the temperature-sensing bag to be placed near the heating wire, making it convenient to install and arrange the entire temperature controller.

[0023] By setting up a second temperature-sensing diaphragm box, which is connected to the capillary tube and hydraulic lines, the second temperature-sensing diaphragm box can have a pre-pressure. When a leak occurs in the hydraulic lines, the second temperature-sensing diaphragm box can release pressure, thus playing a protective role. It can also separate and disconnect the moving and fixed contacts of the hydraulic thermostat, thereby achieving the disconnection protection of the hydraulic thermostat. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] This embodiment discloses a hydraulic temperature controller with protection, referring to... Figures 1-3 As shown, it includes a support shell 1, a first contact piece 2, a second contact piece 3, an elastic sheet assembly 4, a support block 5, an adjusting screw 6, and a temperature sensing diaphragm box 7. The first contact piece 2 and the second contact piece 3 are respectively fixedly installed on the support shell 1, serving as the two power terminals of the temperature controller.

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

[0033] The movable contact 42 is located between the support piece 41 and the second contact 3. The connecting end 421 of the movable contact 42 is fixed to the second end 412 of the support piece 41, and the movable end 422 of the movable contact 42 extends to the outside of the first contact 2. A fixed contact 21 is riveted to the first contact 2, and a movable contact 423 is riveted to the movable end 422 of the movable contact 42. When the movable contact 423 and the fixed contact 21 are close to each other, they can achieve conduction; when the movable contact 423 is far from the fixed contact 21, they can achieve disconnection, thus realizing on / off switching.

[0034] One end of the temperature-regulating elastic sheet 43 is connected to the first end 411 of the support sheet 41, and the other end is elastically inclined and bent away from the moving contact sheet 42. The temperature-regulating elastic sheet 43 has a certain degree of elasticity. One end of the arc-shaped elastic sheet 44 is connected to the movable end 422 of the moving contact sheet 42, and the other end is elastically abutting against the temperature-regulating elastic sheet 43. The arc-shaped elastic sheet 44 has a downwardly convex arc-shaped structure, with its left end extending upward and pressing against the temperature-regulating elastic sheet 43, which can realize the mutual linkage between the temperature-regulating elastic sheet 43 and the arc-shaped elastic sheet 44.

[0035] Reference Figure 1 As shown, the adjusting screw 6 is threaded to the support housing 1 and is located on the upper side of the elastic sheet assembly 4. The temperature-sensing diaphragm box 7 is installed at the end of the adjusting screw 6 and can abut against the side of the temperature-regulating elastic sheet 43 facing away from the moving contact piece 42.

[0036] Specifically, a connecting post 71 is fixedly connected to one side of the temperature-sensing diaphragm box 7, and an insulating post 72 is fixedly connected to the other side. The connecting post 71 is fixedly connected to the end of the adjusting screw 6. An inner hole is opened at the end of the adjusting screw 6, and the connecting post 71 is inserted into the end of the adjusting screw 6 and bonded in place. The insulating post 72 elastically abuts against the temperature-regulating elastic sheet 43 in the direction of the moving contact plate 42. By aligning the insulating post 72 with the temperature-regulating elastic sheet 43 of the elastic sheet assembly 4, the temperature-regulating elastic sheet 43 can be adjusted.

[0037] Reference Figure 1 As shown, the hydraulic thermostat in this embodiment also includes a temperature-sensing bladder 8, which is connected to a temperature-sensing diaphragm box 7 via a capillary tube 81. The temperature-sensing bladder 8 is installed near the heating wire of the appliance to detect the degree of heating. When the temperature-sensing bladder 8 detects a temperature increase, the liquid inside the bladder 8 expands, increasing the pressure. This causes the two sides of the temperature-sensing diaphragm box 7 to expand, applying pressure to the arc-shaped elastic sheet 44. The left end of the arc-shaped elastic sheet 44 is pressed down, while the right end rises, applying an upward force to the moving contact sheet 42. This causes the moving contact point 423 at the right end of the moving contact sheet 42 to deflect upward. When the temperature-sensing bladder 8 detects a further increase in temperature to the temperature control limit, the moving contact point 423 of the moving contact sheet 42 separates from the fixed contact point 21 of the contact sheet 2, thus disconnecting the thermostat.

[0038] By adjusting the screw 6, the positions of the screw 6 and the temperature sensing diaphragm 7 can be adjusted in advance, thereby adjusting the force of the temperature regulating elastic plate 43 in advance, adjusting the temperature control limit of the temperature controller, and adjusting the temperature control limit of the temperature controller.

[0039] Reference Figures 1-3 As shown, the support block 5 presses against the support plate 41 on the side facing away from the adjusting screw 6, as indicated. Figure 1The support block 5 is located on the lower side of the support plate 41 and can provide support by pressing against the lower side of the support plate 41. A support cylinder 51 is fixedly connected inside the support shell 1, and the support cylinder 51 can be used as support for the support block 5.

[0040] A stepped support surface 511 facing the support piece 41 is formed on the inner circumference of the support cylinder 51. During installation, part of the support block 5 is embedded in the inner circumference of the support cylinder 51, which can realize the fitting and limiting of the support block 5. The lower end of the support block 5 can abut against the stepped support surface 511, which can realize the function of supporting the support block 5.

[0041] A support screw 52 is threaded onto the inner circumference of the support cylinder 51. A spring 53 elastically presses against the support block 5 at the upper end of the support screw 52. Part of the spring 53 is embedded in the end face of the support block 5. During installation, the spring 53 and the stepped support surface 511 jointly apply pressure to the support block 5, thus supporting the support block 5.

[0042] By adjusting the threaded support screw 52, ​​pressure can be applied upward to the spring 53, which in turn can apply pressure upward to the support block 5.

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

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

[0045] Furthermore, the force is transmitted between the temperature-sensing diaphragm 9 and the second end 412 of the support plate 41 via a linkage rod 10. (Refer to...) Figure 1 As shown, in this embodiment, the hydraulic thermostat also includes a linkage rod 10. The linkage rod 10 is located on the side of the support plate 41 facing away from the support block 5. The linkage rod 10 has a hinge end 101 and a pressing end 102. The hinge end 101 is located on the left side and is rotatably connected to the support shell 1. The pressing end 102 extends to the right and can press against the side (i.e., the upper side) of the second end 412 of the support plate 41 facing away from the support block 5.

[0046] Furthermore, the second temperature-sensing diaphragm 9 is located on the side of the linkage rod 10 facing away from the support plate 41. One side of the second temperature-sensing diaphragm 9 is installed on the support shell 1, and the other side presses against the linkage rod 10. The pressing position of the second temperature-sensing diaphragm 9 is located near the hinge end 101 of the linkage rod 10. The distance between the second temperature-sensing diaphragm 9 and the pressing position of the linkage rod 10 is approximately 1 / 3 to 1 / 2 of the length of the linkage rod 10, which can form a lever-like structure. A small floating deflection action is formed at the second temperature-sensing diaphragm 9, which can amplify the deflection amplitude at the pressing end 102 of the linkage rod 10, thereby increasing the deflection and floating of the second end 412 of the support plate 41.

[0047] Furthermore, the temperature-sensing diaphragm 2 9 is connected to the capillary tube 81. The temperature-sensing diaphragm 2 9 can also expand and contract in response to the expansion and contraction of the liquid.

[0048] When the temperature sensing capsule 8 detects an increase in temperature, the liquid inside the temperature sensing capsule 8 will expand, and the pressure will increase. Both the temperature sensing diaphragm box 1 7 and the temperature sensing diaphragm box 2 9 will expand to a certain extent. The expansion and contraction of the temperature sensing diaphragm box 1 7 will drive the temperature regulating elastic sheet 43 to move, which in turn drives the elastic sheet assembly 4 to move, enabling the switching between the moving contact 423 and the fixed contact 21 of the elastic sheet assembly 4.

[0049] Simultaneously, the second temperature-sensing diaphragm 9 can also expand. After expansion, the second temperature-sensing diaphragm 9 can further press down the linkage rod 10. The pressing end 102 of the linkage rod 10, the second end 412 of the support plate 41, the support block 5, and the stepped support surface 511 press against each other to limit the position, which can keep the second end 412 of the support plate 41 stable and unaffected by the downward pressure of the second temperature-sensing diaphragm 9. When the hydraulic lines of the temperature-sensing bladder 8, capillary tube 81, first temperature-sensing diaphragm 7, and second temperature-sensing diaphragm 9 leak (for example, the temperature-sensing bladder 8 detects excessively high temperature and leaks, or the lines of the temperature-sensing bladder 8 and capillary tube 81 are damaged and leak), the hydraulic pressure in the lines will leak, and the original pressure will be depressurized. The pressure inside the second temperature-sensing diaphragm 9 will disappear and will be compressed back. After the pressure inside the temperature sensing diaphragm box 29 disappears, the downward pressure on the lower side of the temperature sensing diaphragm box 29 and the linkage rod 10 will decrease. The linkage rod 10 can deflect slightly upward. The downward pressure of the pressing end 102 of the linkage rod 10 on the second end 412 of the support plate 41 will not be able to overcome the elastic force of the spring 53, thereby causing the second end 412 of the support plate 41 to deflect upward. This allows the support plate 41 to drive the moving contact plate 42 to shift upward, thereby causing the moving contact 423 of the moving contact plate 42 to move up and down. This allows the moving contact 423 to separate upward from the fixed contact 21, and the hydraulic thermostat will be disconnected.

[0050] By setting the temperature-sensing diaphragm box 29, it can play a protective role when the hydraulic pipeline leaks, and can separate and disconnect the moving contact 423 and the fixed contact 21 of the hydraulic thermostat, so as to realize the disconnection protection of the hydraulic thermostat.

[0051] Example 2

[0052] This embodiment discloses a hydraulic temperature controller with protection. Based on Embodiment 1, and further referring to... Figure 4 A detailed explanation will be provided.

[0053] Furthermore, referring to Figure 4 As shown, the second temperature-sensing diaphragm 9 and the capillary tube 81 are connected by a connecting member 91. The connecting member 91 has a connecting cavity and is connected to a first connecting capillary tube 911 and a second connecting capillary tube 912. The first connecting capillary tube 911 connects to the second temperature-sensing diaphragm 9, and the second connecting capillary tube 912 connects to the capillary tube 81, thus connecting the second temperature-sensing diaphragm 9 to the hydraulic flow channel. The second temperature-sensing diaphragm 9 can be affected by the hydraulic pressure and undergo corresponding deformation.

[0054] The connecting member 91 has a cylindrical structure, and its inner cavity is also cylindrical. A piston 92 is installed inside the connecting member 91, and a connection port 94 is provided at the upper end of the connecting member 91. The lower part and side of the connecting member 91 are connected to a first connecting capillary tube 911 and a second connecting capillary tube 912, which can communicate with the inner cavity of the connecting member 91.

[0055] An internal thread is machined into 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 screw member 93 is threadedly connected to the inner circumference of the connection port 94, and 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 inner cavity pressure of the connecting member 91, which in turn allows for corresponding adjustment of the initial pressure inside the second temperature-sensing diaphragm box 9 and the first temperature-sensing diaphragm box 7. By adjusting the internal pressure of the second temperature-sensing diaphragm box 9, it achieves an initial thickness. After a leak occurs due to damage to the hydraulic pipeline, the inner cavity of the second temperature-sensing diaphragm box 9 will depressurize, allowing its thickness to be compressed and reduced. This reduces the limiting effect on the linkage rod 10, allowing the linkage rod 10 to swing up and down, enabling the support plate 41 to move upwards, which in turn allows the moving contact plate 42 to deflect upwards, thus disconnecting the temperature controller.

[0056] In addition, before the debugging operation, the internal pressure of the temperature sensing diaphragm box 9 can be pre-adjusted by adjusting the screw 93, and the compression of the spring 53 can be pre-adjusted by the support screw 52. Then the entire temperature controller is adjusted and calibrated. After the adjustment is completed, a seal is welded between the screw 93 and the connection port 94 to seal and fix the connection port 94.

[0057] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
