It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for the purpose of facilitating and clearly aiding in the description of embodiments of the application.

As shown in fig. 1, 2 and 5, an infrared detection device includes: a base 12, a shell 2 and an inner sleeve 5; wherein, the uniform end of the outer shell 2 and the inner sleeve 5 is connected with one side of the base 12, the other end is open, the outer shell 2 is provided with a cylindrical cavity, the inner sleeve 5 is positioned in the cylindrical cavity to divide the cylindrical cavity into an outer cavity 4 and an inner cavity 13, the outer cavity 4 and the inner cavity 13 are respectively positioned outside and inside the inner sleeve 5, and the inner cavity 13 is used for accommodating the infrared probe 14; the side wall of the housing 2 is provided with an air inlet pipe 11, the air inlet pipe 11 is communicated with the outer cavity 4, and the end part of the air inlet pipe 11 is provided with a flange 10 for connecting other parts. The base 12, the outer shell 2 and the inner sleeve 5 may also be manufactured as an integral structure.

The outer shell 2 and the inner sleeve 5 are of annular structures in section, and the inner diameters of the outer shell 2 and the inner sleeve 5 are different, so that an annular outer cavity 4 used for air flow is arranged between the outer shell 2 and the inner sleeve 5, and air flow towards the opening end of the outer shell 2 can be formed in the outer cavity 4 by means of the air inlet pipe 11, so that on one hand, the inner sleeve 5 protects the infrared probe 14, on the other hand, dust entering the inner cavity 13 can be reduced by the air flow, and the probability of dust enrichment on the infrared probe 14 is reduced, so that the infrared detection device is particularly suitable for high-dust environments.

In some embodiments, the middle of the base 12 is provided with the wire outlet hole 1, the wire outlet hole 1 is communicated with the inner cavity 13, and is used for allowing the probe wire 16 of the infrared probe 14 to pass through, so that the infrared probe 14 can be conveniently moved out and moved into the inner cavity 13, the shape of the inner cavity 13 can be more adapted to the infrared probe 14, and the problems of heat accumulation and the like caused by accumulation of the probe wire 16 in the inner cavity 13 are reduced.

Further, the inner wall of the inner sleeve 5 is provided with an inner wall thread groove 3 which is matched with the external thread 15 arranged on the infrared probe 14, so that the infrared probe 14 can be fixed in the inner cavity 13 of the inner sleeve 5 through the external thread 15 and the inner wall thread groove 3, shaking in the using process is reduced, and stability is improved.

Continuing to combine with fig. 3 and 4, one end of the infrared probe 14 is provided with a hexagonal inner hole 17, so that the external thread 15 and the inner wall thread groove 3 can be fastened conveniently by using a hexagonal screwdriver through the rotation of the hexagonal inner hole 17.

In some embodiments, continuing with fig. 5, the infrared detection device further comprises an outer end cap 7 and an inner end cap 8; the outer end cover 7 is positioned at the opening end of the shell 2, the outer end cover 7 is provided with a first through hole, and the outer cavity 4 and the inner cavity 13 are communicated with the external environment through the first through hole; the inner end cap 8 is located at the opening end of the inner sleeve 5 and inside the first through hole, the inner end cap 8 has a second through hole, and the inner cavity 13 is communicated with the external environment through the second through hole. That is, at least a portion of the first through hole is not shielded by the inner end cap 8 in a cross-section, so that the air flow formed in the outer cavity 4 toward the open end of the outer shell 2 can be ejected through the first through hole (i.e., the gap between the outer end cap 7 and the inner end cap 8), and thus the direction and speed of the air flow 20 ejected from the nozzle 19 can be controlled by controlling the shapes of the outer end cap 7 and the inner end cap 8, so as to better block dust from entering the inner cavity 13, reduce the area of the infrared probe 14 exposed to the external environment, and better protect the infrared probe 14.

Preferably, the outer end socket 7 is detachably connected to the open end of the outer shell 2, the inner end socket 8 is detachably connected to the open end of the inner sleeve 5, so that the outer end socket 7 and the inner end socket 8 with different shapes can be conveniently detached and cleaned, and the outer end socket 7 and the inner end socket 8 with different shapes can be conveniently replaced according to practical scenes. For example, an outer wall thread groove 6 of the open end of the outer shell and an inner wall thread groove 9 of the open end of the inner sleeve are arranged, corresponding matched threads are respectively formed on the inner side of the outer end sleeve 7 and the outer side of the inner end sleeve 8, so that the outer end sleeve 7 can be detachably connected with the open end of the outer shell 2, and the inner end sleeve 8 can be detachably connected with the open end of the inner sleeve 5.

In some embodiments, there is no contact between the outer end socket 7 and the inner end cap 8, i.e. the first through hole outside the inner end cap 8 is annular when viewed in cross section, so that air flow can be sprayed out around the second through hole, and dust shielding effect is improved.

In some embodiments, in the direction from the base 12 to the inner end cap 8, the inner diameters of the first through hole and the second through hole are gradually reduced, that is, the side walls of the outer end cap 7 and the inner end cap 8 are inclined towards the central axis of the inner cavity 13, so that the air flow is ejected in a nearly conical shape, and the dust shielding effect is improved.

Preferably, the first angle between the side wall of the outer end cap 7 and the central axis of the inner cavity 13 is between 30 ° and 60 °, such as 30 °, 35 °,40 °, 45 °, 50 °, 55 °, 60 °, etc., and the second angle between the side wall of the inner end cap 8 and the central axis of the inner cavity 13 is between 30 ° and 60 °, such as 30 °, 35 °,40 °, 45 °, 50 °, 55 °, 60 °, etc.

Preferably, the side wall of the outer end cap 7 is parallel to the side wall of the inner end cap 8, so that the ejected air flow is more uniform.

Referring to fig. 5, the infrared detection device operates according to the following principle: when the infrared probe 14 is opened, compressed air 18 is input from the air inlet pipe 11, the compressed air 18 passes through the outer cavity 4 to reach the nozzle 19, a gap channel between the outer end socket 7 and the inner end socket 8 is sprayed out towards the direction forming an included angle of 45 degrees with the central line of the inner cavity 13 to form a conical air jet flow 20, and the compressed air forms a conical air flow field after being sprayed out from the nozzle to prevent dust from entering the inner cavity 13. Meanwhile, the second through hole of the inner end cap 8 forms an infrared laser port, infrared laser 21 is emitted, the conical airflow forms a protective cover, dust is prevented from entering the inner cavity 13 to affect the infrared probe 14, but a small hole is exposed for the infrared laser 21 to penetrate, and the infrared probe 14 is ensured to work normally.

In view of the foregoing detailed description of the preferred embodiments, it is intended that the features and spirit of the application be more clearly described rather than limiting the scope of the application as defined by the foregoing description of the preferred embodiments. On the contrary, the intent is to cover all modifications and equivalent arrangements included within the scope of the appended claims.
