[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0031] According to an embodiment of the present invention, a liquid temperature detection component is provided, comprising:

[0032] Pipe 1 contains liquid;

[0033] The second connector 3 is fixedly connected to the pipe 1. The second connector 3 has a second channel 31 inside. The outer wall of the second channel 31 is in contact with the liquid. The second channel 31 forms an opening at the end of the second connector 3 away from the pipe 1.

[0034] Temperature detector 4 is detachably connected to second connector 3. The probe 41 of temperature detector 4 extends into second channel 31 through an opening. A heat-conducting medium is provided between the inner wall of second channel 31 and probe 41.

[0035] The liquid temperature detection component provided in this embodiment is not connected to the inside of the pipe 1 through the second channel 31. When it is necessary to maintain and repair the temperature detector 4, it is only necessary to remove the temperature detector 4 from the second connector 3 without disconnecting the liquid in the pipe, which facilitates the maintenance and repair of the temperature detector 4.

[0036] Specifically, the liquid flows and is transported inside pipe 1. The outer wall of the second channel 31 is in contact with the liquid. The temperature of the liquid is transferred through the outer wall of the second channel 31 to the heat-conducting medium in contact with the inner wall of the second channel 31, and then through the heat-conducting medium to the probe 41. Thus, the temperature detector 4 can detect the temperature of the liquid without being in contact with it. Since the second channel 31 is not connected to the inside of pipe 1, and the temperature detector 4 is detachably connected to the second connector 3, when maintenance or repair of the temperature detector 4 is required, it is not necessary to disconnect the liquid in the pipe; the temperature detector 4 can be directly removed for maintenance or repair, which is convenient.

[0037] In one embodiment, combined Figure 3 and Figure 4 As shown, the heat transfer medium includes heat transfer oil.

[0038] Specifically, the heat-conducting medium includes heat-conducting oil, water, and thermal grease. The opening of the second channel 31 is vertically upward or inclined upward to prevent fluid heat-conducting medium such as heat-conducting oil or water from flowing out of the opening after the temperature detector 4 is removed.

[0039] In one embodiment, combined Figure 3 and Figure 4 As shown, a sealing gasket 6 is provided between the inner wall of the second channel 31 near the opening and the probe 41. The sealing gasket 6 is suitable for sealing the gap between the inner wall of the second channel 31 and the probe 41.

[0040] The liquid temperature detection component provided in this embodiment prevents leakage of heat transfer oil in the gap between the inner wall of the second channel 31 and the probe 41 by setting a sealing gasket 6.

[0041] Specifically, the probe 41 is cylindrical, the sealing gasket 6 is annular and sleeved on the probe 41, and the sealing gasket 6 is in a compressed state so that the inner circumferential surface of the sealing gasket 6 abuts against the outer circumferential wall of the probe 41, and the outer circumferential surface of the sealing gasket 6 abuts against the inner wall of the second channel 31.

[0042] In one embodiment, combined Figure 3 and Figure 4 As shown, the inner wall of the second channel 31 near the opening is provided with an internal thread, and the temperature detector 4 is provided with an external thread corresponding to the internal thread, so that the temperature detector 4 is threadedly connected to the second connector 3.

[0043] Specifically, the temperature detector 4 has a threaded portion 42, with an external thread formed on the threaded portion 42. The diameter of the threaded portion 42 is larger than the diameter of the probe 41. The second channel 31 has a convex surface 311 inside. Along the length direction of the probe 41, the two end faces of the sealing gasket 6 abut against the threaded portion 42 and the convex surface 311 respectively, thereby ensuring the stability of the sealing gasket 6.

[0044] In one embodiment, combined Figure 3 As shown, a first magnet is provided near the opening of the second channel 31, and a second magnet is provided for the temperature detector 4 corresponding to the first magnet. The first magnet and the second magnet are adapted to be magnetically connected.

[0045] Specifically, the first magnet is fixedly connected to the opening of the second channel 31, and the second magnet is fixedly connected to the temperature detector 4 at a position corresponding to the opening, so that the temperature detector 4 can be detachably connected to the second connector 3 through the magnetic attraction of the second magnet and the first magnet.

[0046] In one embodiment, combined Figures 1 to 6 As shown, the liquid temperature detection assembly also includes a first connector 2, which is fixedly connected to the pipe 1. A first channel 21 is provided through the first connector 2, which is connected to the inside of the pipe 1. A second connector 3 is fixedly connected to the first connector 2, and a portion of the second connector 3 extends into the first channel 21.

[0047] Specifically, the first channel 21 is connected to the pipe 1 to allow liquid to enter the first channel 21, and a portion of the second connector 3 extends into the first channel 21 so that the outer wall of the second channel contacts the liquid for heat transfer.

[0048] In one embodiment, combined Figure 3 As shown, the inner wall of the first channel 21 away from the pipe 1 is provided with an internal thread, and the second connector 3 is provided with an external thread corresponding to the internal thread, so that the first connector 2 and the second connector 3 are threadedly connected.

[0049] In one embodiment, combined Figure 3 and Figure 4 As shown, a sealing element 5 is provided between the end of the first channel 21 away from the pipe 1 and the second connector 3. The sealing element 5 is suitable for sealing the gap between the inner wall of the first channel 21 and the second connector 3.

[0050] The liquid temperature detection component provided in this embodiment prevents leakage of liquid in the pipe 1 at the gap between the inner wall of the first channel 21 and the second connector 3 by setting a sealing element 5.

[0051] Specifically, the sealing element 5 can be threadlocker or a gasket. When a gasket is selected, the gasket is annular and is fitted onto the second connector 3. The gasket is clamped between the first connector 2 and the second connector 3, thereby sealing the gap between the inner wall of the first channel 21 and the second connector 3, thus preventing the liquid in the first channel 21 from leaking at the gap.

[0052] In one embodiment, combined Figures 1 to 6 As shown, along the length of pipe 1, the projection of the second channel 31 overlaps with the projection of the inner channel of pipe 1.

[0053] The liquid temperature detection component provided in this embodiment ensures the contact effect between the outer wall of the second channel 31 and the liquid inside the pipe 1 by having a portion of the second channel 31 located inside the pipe 1, thereby ensuring the detection effect of the temperature detector 4.

[0054] Specifically, the end of the second connector 3 closest to the pipe 1 extends into the inside of the pipe 1 through the first channel 21, and a portion of the second channel 31 is located inside the pipe 1, thereby ensuring the detection effect of the probe 41 in detecting the liquid inside the pipe 1 through the second channel 31.

[0055] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
