Description

Technical Field

[0001] This application relates to the field of temperature sensing technology, and in particular to a thermocouple connection structure for an electromagnetic valve in a stove. Background Technology

[0002] Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They directly measure temperature and convert the temperature signal into a thermoelectric potential signal. They have a wide range of applications, such as in the use of solenoid valves in the field of gas technology.

[0003] Solenoid valves are a common basic component in the field of gas technology. They are actuators with a wide range of applications, including mechanical control and daily life. When used with thermocouples, the solenoid valve is installed in the gas valve cavity of the stove and acts as a switch. The temperature receiving end of the thermocouple is in contact with the gas flame, and the other end of the thermocouple is connected to the solenoid valve. When the temperature of the thermocouple receiving end rises, a current is generated and transmitted to the solenoid valve. The moving iron core and the stationary iron core inside the solenoid valve attract each other, and the valve core retracts, allowing the gas outlet of the appliance to flow freely. Conversely, if the temperature rises, the gas outlet of the appliance is closed.

[0004] In daily operation, thermocouples are usually in environments with heavy oil stains, dirt, and moisture, such as kitchens. In the current technology, the connecting wires of thermocouples are directly exposed in the complex working environment, which causes the outer sheath of the connecting wires to be contaminated. Over time, this will cause corrosion of the connecting wires and reduce their service life. Utility Model Content

[0005] This utility model provides a thermocouple connection structure for an electromagnetic valve in a stove, which prevents the thermocouple's connecting wires from being contaminated and corroded during daily operation, thereby extending the service life of the thermocouple connecting wires.

[0006] To achieve the aforementioned objectives, this application adopts the following technical solution:

[0007] A thermocouple connection structure for an electromagnetic valve in a stove, characterized in that it includes:

[0008] A thermocouple mechanism connected to one end of a connecting wire;

[0009] A connecting mechanism connected to the other end of the connecting wire, the connecting mechanism being connected to a solenoid valve, the connecting mechanism including a connecting sleeve, the connecting sleeve having an A end;

[0010] An adjustable protection mechanism is sleeved on the outside of the connecting wire. The protection mechanism includes a protective sleeve and an adjusting shell connected to one end of the protective sleeve. The adjusting shell has an adjusting chamber and a receiving chamber inside. The adjusting shell has an inlet at one end near the adjusting chamber and an outlet at one end near the receiving chamber. The outlet of the adjusting shell cooperates with end A of the connecting sleeve. The adjusting chamber and the receiving chamber are arranged sequentially along a first preset direction inside the adjusting shell.

[0011] In some alternative embodiments, the outer side wall of the protective sleeve is provided with an external thread, and the inner side wall of the adjusting shell near the inlet is provided with an internal thread. The external thread and the internal thread cooperate, and the adjusting shell is sleeved on the protective sleeve at the end away from the thermocouple mechanism.

[0012] In some alternative embodiments, a limiting piece is provided on end A of the connecting sleeve, and the limiting piece at end A of the connecting sleeve abuts against the inner sidewall of the outlet of the adjusting shell.

[0013] In some alternative embodiments, the outer diameter of the connecting sleeve is L1, the outer diameter of the limiting piece is L2, and the diameter of the outlet of the adjusting shell is L5.<L5,L2> L5.

[0014] In some alternative embodiments, the inlet diameter of the adjusting shell is L4, the outer diameter of the protective sleeve is L3, L4>L3, and L5>L4. <L3。

[0015] In some optional embodiments, the connecting mechanism further includes a connecting body and a connecting head connected to the connecting body, the connecting body being connected to the connecting sleeve, and the connecting mechanism consisting of the connecting sleeve, the connecting body, and the connecting head in sequence along a second preset direction.

[0016] In some alternative embodiments, the thermocouple mechanism comprises two identical thermocouples; both identical thermocouples are connected to the connecting wire.

[0017] The thermocouple connection structure for the electromagnetic valve in the stove provided in this application has the following advantages:

[0018] In the technical solution adopted in this application, one end of the connecting wire is connected to the thermocouple mechanism, and the other end of the connecting wire is connected to the connecting mechanism and an adjustable protective mechanism sleeved outside the connecting wire. The connecting sleeve on the connecting mechanism has an A end, and the adjusting shell in the protective mechanism is connected to the outside of the protective sleeve. The adjusting shell has an adjusting chamber and a receiving chamber inside. The adjusting chamber and the receiving chamber are arranged sequentially along a first preset direction inside the adjusting shell. The adjusting shell has an inlet at the end near the adjusting chamber and an outlet at the end near the receiving chamber. The outlet of the adjusting shell cooperates with the A end of the connecting sleeve so that the protective sleeve can be sleeved on the outer wall of the exposed connecting wire during the daily operation of the thermocouple. When the protective sleeve is damaged and needs to be replaced, it is only necessary to cut off the protective sleeve of the current connected wire that is damaged and rotate the adjusting shell so that the new protective sleeve gradually extends from the inside of the adjusting shell from the receiving chamber to the adjusting chamber until it can completely protect the exposed connecting wire. This prevents the connecting wire from being contaminated and corroded, and extends the service life of the thermocouple connecting wire. Attached Figure Description

[0035] refer to Figure 1 , Figure 1 This is a schematic diagram of a thermocouple connection structure for an electromagnetic valve in a stove, as described in this application. Figure 1 As shown, a thermocouple connection structure for a solenoid valve in a stove includes a thermocouple mechanism 10 connected to one end of a connecting wire 40, a connecting mechanism 20 connected to the other end of the connecting wire 40, and an adjustable protection mechanism 30 sleeved outside the connecting wire 40. The thermocouple mechanism 10 includes two identical thermocouples 11; each of the two identical thermocouples 11 is connected to a connecting wire 40, and the connecting mechanism 20 is connected to a solenoid valve.

[0036] Here, one end of the connecting wire 40 is connected to the thermocouple mechanism 10, and the other end of the connecting wire 40 is connected to the connecting mechanism 20 and the adjustable protective mechanism 30 sleeved on the outside of the connecting wire 40. This allows the protective sleeve 31 to be sleeved on the outer wall of the exposed connecting wire 40 during the daily operation of the thermocouple 11, thereby preventing the connecting wire 40 from being contaminated and corroded, and extending the service life of the connecting wire 40 of the thermocouple 11.

Figure 2 , Figure 2 This is a schematic diagram of the connecting sleeve in a thermocouple connection structure for an electromagnetic valve in a stove, as described in this application. Figure 1 and Figure 2 As shown, the connecting mechanism 20 includes a connecting sleeve 21, a connecting body 22 connected to the connecting sleeve 21, and a connecting head 23 connected to the connecting body 22. The connecting sleeve 21 has an A end, and a limiting piece 211 is provided on the A end of the connecting sleeve 21. The connecting mechanism 20 consists of the connecting sleeve 21, the connecting body 22, and the connecting head 23 in sequence along the second preset direction. The outer diameter of the connecting sleeve 21 is L1, the outer diameter of the limiting piece 211 is L2, the connecting sleeve 21 is cylindrical, and the connecting head 23 is connected to a solenoid valve.

[0038] refer to Figure 3 , Figure 3 This is a partial structural diagram of the protection mechanism in a thermocouple connection structure for an electromagnetic valve in a stove, as described in this application. Figure 3 As shown, the protective mechanism 30 includes a protective sleeve 31 and an adjustment shell 32 connected to one end of the protective sleeve 31. Here, the protective sleeve 31 is made of a stackable soft material.

[0039] Continue to refer to Figure 1 Please refer to them together. Figure 4 , Figure 4 This is a partial structural diagram of the protective sleeve in the thermocouple connection structure of an electromagnetic valve for a stove, as described in this application. Figure 1 and Figure 4 As shown, the outer wall of the protective sleeve 31 is provided with an external thread 311, and the adjusting shell 32 is sleeved on the protective sleeve 31 at the end away from the thermocouple 11 mechanism 10.

[0040] Continue to refer to Figure 3Please refer to them together. Figure 5 , Figure 5 This is a schematic diagram of the regulating shell in a thermocouple connection structure for an electromagnetic valve in a stove, as described in this application. Figure 3 and Figure 5 As shown, the interior of the regulating shell 32 is provided with an regulating chamber 321 and a receiving chamber 322. The regulating chamber 321 and the receiving chamber 322 are arranged sequentially along a first preset direction. The regulating shell 32 has an inlet 323 at the end near the regulating chamber 321 and an outlet 324 at the end near the receiving chamber 322. The inner sidewall of the regulating shell 32 near the inlet 323 is provided with an internal thread 325, and the external thread 311 cooperates with the internal thread 325. The outlet 324 of the regulating shell 32 cooperates with the A end of the connecting sleeve 21. Specifically, the limiting piece 211 at the A end of the connecting sleeve 21 abuts against the inner sidewall of the outlet 324 of the regulating shell 32, so that the regulating shell 32 can rotate freely around the connecting sleeve 21, and the regulating shell 32 and the connecting sleeve 21 do not separate.

[0041] Here, the adjustment chamber 321 is formed by the mutual cooperation between the external thread 311 of the protective sleeve 31 and the internal thread 325 of the adjustment shell 32, so that the protective sleeve 31 extends out of the receiving chamber 322 and protects the connecting wire 40 after passing through the adjustment chamber 321. At the same time, the receiving chamber 322 is used to store the protective sleeve 31. Several meters of protective sleeve 31 are stacked inside the receiving chamber 322 to facilitate the replacement of damaged protective sleeve 31 during daily use.

[0042] Continue to refer to Figure 2 , Figure 4 and Figure 5 Wherein, the outer diameter of the protective sleeve 31 is L3, the diameter of the inlet 323 of the adjusting shell 32 is L4, the diameter of the outlet 324 of the adjusting shell 32 is L5, and L1<L5,L2> L5, L4 > L3, L5 <L3。

[0043] Here, the outer diameter L1 of the connecting sleeve 21 is smaller than the diameter L5 of the outlet 324 of the adjusting shell 32, and the outer diameter L2 of the limiting piece 211 is larger than the diameter L5 of the outlet 324 of the adjusting shell 32, so that the adjusting shell 32 can rotate freely around the connecting sleeve 21 and the adjusting shell 32 does not separate from the connecting sleeve 21; the diameter L4 of the inlet 323 of the adjusting shell 32 is larger than the outer diameter L3 of the protective sleeve 31, and the diameter L5 of the outlet 324 of the adjusting shell 32 is smaller than the outer diameter L3 of the protective sleeve 31, so that the protective sleeve 31 can freely enter and exit the adjusting shell 32 through the outlet 324.

[0044] Here, the connecting sleeve 21 on the connecting mechanism 20 has an A end, and the adjusting shell 32 in the protection mechanism 30 is connected to the outside of the protective sleeve 31. The adjusting shell 32 has an adjusting chamber 321 and a receiving chamber 322 inside. The adjusting chamber 321 and the receiving chamber 322 are arranged sequentially along the first preset direction inside the adjusting shell 32. The adjusting shell 32 has an inlet 323 at the end near the adjusting chamber 321 and an outlet 324 at the end near the receiving chamber 322. The outlet 324 of the adjusting shell 32 is matched with the A end of the connecting sleeve 21. When the protective sleeve 31 is damaged and needs to be replaced, it is only necessary to cut off the protective sleeve 31 of the damaged current connecting wire 40 and rotate the adjusting shell 32 so that the new protective sleeve 31 gradually extends from the inside of the adjusting shell 32 from the receiving chamber 322 to the adjusting chamber 321 until it can completely protect the exposed connecting wire 40, thereby further protecting the connecting wire 40 from contamination and corrosion and extending the service life of the thermocouple 11 connecting wire 40.

[0045] To facilitate understanding, the working principle of this application is further described as follows: When the solenoid valve thermocouple connection structure of the stove is used for the first time, the receiving chamber 322 inside the regulating shell 32 has several meters of protective sleeve 31 stacked on it. At the same time, the external thread 311 of the protective sleeve 31 and the internal thread 325 of the regulating chamber 321 are also mutually engaged. The connecting end of the connecting wire 40 with the thermocouple mechanism 10 passes through the protective mechanism 30 and the connecting mechanism 20 in sequence. At this time, the regulating shell 32 is rotated, and the protective sleeve 31 extends out from the receiving chamber 322 of the regulating shell 32 and passes through the regulating chamber 321. At the same time, the protective sleeve 31 is gradually fitted onto the outside of the connecting wire 40 until the exposed connecting wire 40 is completely covered.

[0046] If the protective sleeve 31 of the extended adjustment shell 32 is damaged during later use and is insufficient to protect the exposed connecting wire 40, the damaged protective sleeve 31 outside the adjustment shell 32 can be cut off, and then the adjustment shell 32 can be rotated. At the same time, the protective sleeve 31 can be gradually put on the outside of the connecting wire 40 until the exposed connecting wire 40 is completely covered.
