Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a novel thermocouple temperature control device for stoves. Background Art

[0002] The stove thermocouple temperature control device is a device used to control the flame temperature of the stove. Its principle is that when the flame temperature is lower than the set value, the thermocouple will generate an electrical signal, which will be transmitted to the gas control valve. The control valve will open to allow more gas to enter the combustion chamber, thereby increasing the flame temperature. When the flame temperature is higher than the set value, the electrical signal generated by the thermocouple will decrease, and the control valve will close, reducing the gas supply, thereby lowering the flame temperature.

[0003] At present, the thermocouple of the stove thermocouple temperature control device is installed by screws. Since the stove works at a high temperature, it is easy to cause the screws to creep if it is in a high temperature environment for a long time, making subsequent disassembly difficult and not conducive to the maintenance and replacement of the thermocouple. There is room for improvement. Utility Model Content

[0029] Reference Figure 1-Figure 5 , is an embodiment of the utility model, which provides a new type of stove thermocouple temperature control device, which includes:

[0030] The main body 100 includes a mounting cylinder 101, a mounting ring 102, a thermocouple 103 and a clamping block 104. Two groups of clamping blocks 104 are provided and are fixedly connected to both sides of the thermocouple 103 respectively. The top of the mounting cylinder 101 is opposite to the two groups of clamping blocks 104 and is provided with clamping grooves 101a that match the two groups of clamping blocks 104. The two groups of clamping blocks 104 are respectively embedded in the two groups of clamping grooves 101a. The mounting ring 102 is fixedly sleeved on the outside of the mounting cylinder 101. The top of the mounting cylinder 101 is provided with an arc groove 101b. Two groups of positioning grooves 101c are provided on one side of the top of the mounting cylinder 101 away from the arc groove 101b.

[0031] The limiting mechanism 200 includes a rotating drum 201, a rotating ring 202 and a limiting block 203. The rotating ring 202 is rotatably sleeved on the outside of the mounting drum 101 and is located above the mounting ring 102. The rotating drum 201 is covered on the top of the mounting drum 101 and is fixedly connected to the rotating ring 202. The rotating drum 201 has a through hole at a position facing the thermocouple 103, and the thermocouple 103 passes through the through hole. The rotating drum 201 has a socket 201a that matches the slot 101a at a position facing the two groups of slots 101a. The limiting block 203 is fixedly connected to the inner wall of the top of the rotating drum 201 and is slidably arranged on the inner side of the arc slot 101b.

[0032] The arc center of the arc groove 101b coincides with the axis of the installation cylinder 101, the two sets of positioning grooves 101c are at the same distance from the center of the installation cylinder 101, and when the limit blocks 203 are located at both ends of the arc groove 101b, the two sets of sockets 201a are respectively aligned with or offset from the two sets of slots 101a, and the inner wall of the top of the rotating cylinder 201 fits the top of the installation cylinder 101. The top of the installation ring 102 is also fixedly connected with a locking mechanism 300 for locking the installation cylinder 101 in cooperation with the positioning groove 101c. The locking mechanism 300 includes The second installation cylinder 301, the positioning block 302 and the elastic member 303 are included. The second installation cylinder 301 is fixedly connected to the top of the installation ring 102 and its position is opposite to one of the positioning grooves 101c. The rotating cylinder 201 is provided with an opening at a position opposite to the second installation cylinder 301. The positioning block 302 is slidably arranged inside the second installation cylinder 301 and the opening and its bottom is inserted into the opposite positioning groove 101c. The elastic member 303 is arranged above the positioning block 302 and its two ends are respectively in contact with the second installation cylinder 301 and the positioning block 302.

[0033] Among them, the bottom of the positioning block 302 and the positioning groove 101c are both arc-shaped, ensuring that the positioning groove 101c can push the positioning block 302 out when the drum 201 rotates, and when the limit blocks 203 are located at both ends of the arc groove 101b, the positioning blocks 302 are respectively inserted into the two groups of positioning grooves 101c to ensure the normal function of the device. The curvature of the arc groove 101b is greater than or equal to 45° and less than or equal to 120°, ensuring that the two groups of sockets 201a can be misaligned with the two groups of card slots 101a.

[0034] It should be noted that the mounting cylinder 101, the mounting ring 102, the rotating cylinder 201, the rotating ring 202 and the limit block 203 are all made of cast iron material, which is resistant to high temperatures. The rotating cylinder 201 and the limit block 203 are integrally formed, and the integral forming can ensure the structural strength. The surfaces of the mounting cylinder 101, the mounting ring 102, the rotating cylinder 201 and the limit block 203 are also coated with high-temperature resistant anti-corrosion coating, and the anti-corrosion coating is used to improve the anti-corrosion performance of the device. The surface of the mounting cylinder 101 is smooth to reduce friction. The top of the rotating cylinder 201 is also printed with an indicator mark to indicate the direction of rotation and opening and closing, which can improve the usability of the device.

[0035] Working principle: Fix the installation cylinder 101 to the stove by screws, etc. When installing the thermocouple 103, rotate the rotating cylinder 201 according to the indication mark on the top of the installation cylinder 101. When the rotating cylinder 201 rotates, it drives the limit block 203 to move along the arc groove 101b. When the two groups of sockets 201a are facing the two groups of card slots 101a, the limit block 203 moves to the end of the arc groove 101b, and the rotating cylinder 201 cannot continue to rotate. Under the elastic force of the elastic member 303, the positioning block 302 is inserted into the opposite positioning groove 101c. The rotating cylinder 201 and the installation cylinder 101 remain relatively still, and the two groups of card blocks 104 are respectively passed through the two groups of sockets 201a. After that, the two groups of slots 101a are embedded in the two groups, and the rotating drum 201 is rotated in the opposite direction with force. The positioning block 302 is pushed upward and disengaged from the corresponding positioning slot 101c. The elastic member 303 is compressed. When the limit block 203 is rotated, it presses against the other end of the arc slot 101b. At this time, the two groups of sockets 201a are misaligned with the two groups of slots 101a, and the two groups of blocks 104 are clamped by the rotating drum 201. The positioning block 302 is facing the other group of positioning slots 101c, and the elastic member 303 rebounds to make the positioning block 302 clamped in the positioning slot 101c. The rotating drum 201 and the installation cylinder 101 remain relatively still, and the installation of the thermocouple 103 is completed. The thermocouple 103 can be removed by the subsequent reverse steps.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
