[0025] Next, refer to Figures 1 to 2 to describe a sheath according to an embodiment of the present utility model that is easy for a probe to observe the situation inside the kiln.

[0026] The sheath according to an embodiment of the present utility model that is easy for a probe to observe the situation inside the kiln includes a main body portion 100 and a positioning block 200. A receiving cavity is formed in the main body portion 100 for receiving a probe 700. The positioning block 200 is disposed in the receiving cavity, and a positioning hole 210 is formed through the middle of the positioning block 200. The space between the inner side wall of the main body portion 100 and the positioning block 200 forms an air duct 300, so that the air inside the kiln is concentrated and blown towards the probe 700.

[0027] For example Figure 1As shown, an accommodation cavity is provided inside the main body 100 of the sheath. The positioning hole 210 is arranged in front of the main body 100, and the positioning hole 210 runs through the middle. After the probe 700 is aligned with the positioning hole 210 and placed into the sheath, the air duct 300 formed by the space between the inner side wall of the main body 100 and the positioning block 200 enables the air in the kiln to be concentrated and blown towards the probe 700, so that the dust near the probe 700 is blown away, preventing the dust in the kiln from affecting the detection of the probe 700, ensuring the detection quality of the probe 700. At the same time, the problem of dust accumulation on the probe 700 is solved, eliminating the need for manual cleaning and improving the safety factor.

[0028] The probe 700 can detect the situation inside the kiln through the positioning hole 210. After the air blows away the dust through the air duct 300, the probe 700 can obtain a better view, enabling it to more accurately detect the situation inside the kiln.

[0029] In some specific embodiments of the present utility model, there is also an inclined end block 400. The inclined end block 400 is arranged inside the air duct 300. The outer side wall of the inclined end block 400 is connected to the main body 100, and the inner side wall is inclined, so that the air in the kiln is concentrated and blown towards the probe 700 along the inner side wall of the inclined end block 400.

[0030] For example Figure 1 and Figure 2 As shown, the inclined end block 400 is arranged inside the air duct 300, and its outer side wall is connected to the main body 100. It is triangular when viewed from the side. The inclined inclined end block 400 can make the air in the kiln be concentrated and blown towards the probe 700 along the inner side wall of the inclined end block 400, more conveniently concentrating the air towards the front end of the probe 700, so that the dust at the probe 700 is blown away by the air.

[0031] In some specific embodiments of the present utility model, the inclined end block 400 is annularly connected to the inner side wall of the main body 100, and the inner diameter of the inclined end block 400 gradually decreases along the air inlet direction of the air duct 300.

[0032] For example Figure 1 and Figure 2 As shown, the inclined end block 400 is integrally annularly arranged. The outer side of the annular inclined end block 400 is fixedly connected to the inner side wall of the main body 100, and the inner side wall of the inclined end block 400 is inclined, and the inner diameter gradually decreases along the air inlet direction of the air duct 300, that is, the axial direction of the sheath, so that the air in the kiln can be concentrated and blown towards the probe 700.

[0033] In some specific embodiments of the present utility model, there are also several support blocks 500. The support block 500 includes a connecting portion 510. One end of the connecting portion 510 is connected to the main body 100, and the other end is connected to the positioning block 200.

[0034] For exampleFigure 2 As shown, four support blocks 500 are circumferentially arranged between the positioning block 200 and the sheath. The support block 500 includes a connecting portion 510. One end of the connecting portion 510 is connected to the main body portion 100, and the other end is connected to the positioning block 200, thereby fixing the position of the positioning block 200 and facilitating the probe 700 to align with the positioning hole 210 after being inserted into the receiving cavity of the main body portion 100.

[0035] In some specific embodiments of the present invention, a plurality of support blocks 500 are provided, and the plurality of support blocks 500 are evenly arranged along the circumferential direction of the positioning block 200.

[0036] For example Figure 2 As shown, four support blocks 500 are circumferentially arranged along the positioning block 200, so that the positioning block 200 can be firmly connected to the main body portion 100.

[0037] In some specific embodiments of the present invention, the support block 500 further includes a support portion 520. The support portion 520 is connected to the connecting portion 510 and is arranged in an L shape. The support portion 520 is arranged along the axial direction of the main body portion 100 and is connected to the inner wall of the main body portion 100.

[0038] For example Figure 1 As shown, the support block 500 further includes a support portion 520. The support portion 520 is connected to the support block 500, so that the support block 500 is integrally in an L shape. The support portion 520 is arranged along the axial direction of the main body portion 100 and is connected to the inner side wall of the main body portion 100. The support portion 520 is used to support the probe 700. When the probe 700 extends into the receiving cavity of the main body portion 100, it can be stuck on the support portion 520 of the support block 500, so that the position of the probe 700 can be fixed.

[0039] Furthermore, the connecting portion 510 and the support portion 520 of the support block 500 are integrally formed, making the connection between the connecting portion 510 and the support portion 520 more stable.

[0040] In some specific embodiments of the present invention, a chamfer 521 is provided at the end of the support portion 520 away from the connecting portion 510.

[0041] For example Figure 1 As shown, a chamfer 521 is provided at the end of the support portion 520 away from the connecting portion 510, so that when the probe 700 extends into the receiving cavity, it can more easily enter the positioning block 200, and a certain buffer can be achieved through the chamfer 521.

[0042] In some specific embodiments of the present invention, the positioning hole 210 is frustum-shaped, and the inner diameter of the positioning hole 210 gradually decreases along the air inlet direction of the air duct 300.

[0043] For exampleFigure 1 and Figure 2 As shown in Figure 2 , the positioning block 200 is generally circular as a whole, and a positioning hole 210 is provided in the middle. The positioning hole 210 is frustum-shaped, and the inner diameter gradually decreases along the air inlet direction of the air duct 300, so that the air can be concentrated and blown towards the position of the probe 700.

[0044] In some specific embodiments of the present utility model, a fixing device is provided at the end of the main body portion 100, and the main body portion 100 is detachably connected to the probe 700 through the fixing device.

[0045] Providing a fixing device at the end of the main body portion 100 enables the probe 700 to be fixedly connected to the sheath through the fixing device after the probe 700 extends into the accommodating cavity of the main body portion 100, thereby realizing a detachable connection. When the sheath is damaged due to high temperature, the sheath can be removed, and after replacing it with a new sheath, the probe can be connected to the new sheath, which is convenient for replacement without discarding the probe 700 and the sheath together.

[0046] The fixing device can adopt various ways to detachably connect the probe 700 to the sheath. For example, a bolt can be used to abut against the side wall of the probe 700 through a screw hole to fix the position of the probe 700, or an adjustable screw 600 can be used to fix the probe 700 to the sheath.

[0047] In some specific embodiments of the present utility model, the fixing device is an adjustable screw 600, and the main body portion 100 is detachably connected to the probe 700 through the adjustable screw 600.

[0048] For example Figure 1 As shown in Figure 1 , the fixing device is an adjustable screw 600, enabling the main body portion 100 to be detachably connected to the probe 700 through the adjustable screw 600, which is convenient for replacing the probe 700 or the sheath.

[0049] Furthermore, the sheath is integrally formed as a whole, which is convenient for manufacturing and the connection between each part is more firm and stable.
