The filler may be a foaming material, which may be in a liquid state when stored in the high pressure container, and is in a normal pressure environment after being injected into the injection part 13, so that the foaming material may be solidified in the injection part 13 after a certain time and is tightly connected with the connecting pipe 50, so that a sealing connection is formed between the housing 11 and the connecting pipe 50, the connecting pipe 50 is prevented from being contacted with external water vapor, and a heat insulation effect is provided.

In the splicing process of the refrigeration equipment, the connecting pipe 50 is connected with one refrigeration unit, the shell 11 is sleeved on the connecting pipe 50, the connecting pipe 50 is located in the accommodating part 20, the other refrigeration unit is spliced to the other end of the refrigeration unit, the two refrigeration units are folded, after the refrigeration units are folded, the filler can be injected into the filler injection part 13 through the filler injection opening 30, the filler is stopped from being injected after filling the whole filler injection part 13, the filler can be tightly connected with the connecting pipe 50 after being solidified in the filler injection part 13, so that sealing connection is formed between the shell 11 and the connecting pipe 50, the connecting pipe 50 is prevented from being contacted with external water vapor, and a heat preservation effect is provided.

In some embodiments, as shown in fig. 2, the housing 11 may include: contact surface and adhesive portion 12.

The contact surface may be a portion of the housing 11 that contacts the refrigeration equipment during the splicing of the refrigeration equipment, and illustratively, the contact surface may be a portion of the outer surface of the housing 11 that is adjacent to the receiving portion 20.

The bonding portion 12 may be disposed on the contact surface, so that after the housing 11 contacts with the refrigeration device, the bonding portion 12 may bond the refrigeration device with the housing 11 and seal a gap between the refrigeration device and the housing 11, thereby further preventing the connection pipe 50 from contacting with external water vapor and enhancing the heat insulation effect.

In some embodiments, as shown in fig. 2, the injection port 30 and the exhaust port 40 may be located at opposite sides of the housing 11, respectively, and, as shown in fig. 2, for example, the injection port 30 and the exhaust port 40 may be located at opposite sides in the radial direction of the housing 11. During the splicing process of the refrigeration device, the material injection port 30 can be rotated to the lower end in the gravity direction, the air exhaust port 40 can be rotated to the upper end in the gravity direction, so that the relatively heavy filler fills the material injection part 13 from bottom to top, relatively light air is discharged from above, the air can be completely exhausted from the air exhaust port 40 above, and the filler can completely fill the material injection part 13. And thus it is possible to prevent the filler from blocking the exhaust port 40 in advance during the process of injecting the filler into the filler part 13, so that the normal exhaust is not possible, thereby ensuring the smoothness of the process of injecting the filler into the filler part 13.

In some embodiments, the housing 11 may include: the transfer tube may include a connection end through which the transfer tube may be connected to the opening.

Illustratively, as shown in fig. 2, the transfer pipe may include an exhaust pipe 41, a connection end of the exhaust pipe 41 may be connected to the exhaust port 40, air in the filling portion 13 may be exhausted through the exhaust pipe 41, and whether the filling portion 13 is filled with the filling may be known by observing whether the filling is present in the exhaust pipe 41, so that the filling may be stopped in time after the filling portion 13 is filled with the filling.

In some embodiments, since the capacity of the filling portion 13 is a known parameter, the preset volume capable of filling the filling portion 13 can be calculated according to the capacity of the filling portion 13, the loss of the transmission pipe, and other factors, so that the filling of the filling portion 13 can be stopped in time after the filling of the filling portion 13 is satisfied by setting the filling of the preset volume.

In some embodiments, as shown in fig. 2, the transmission tube may be integrally formed with the housing 11, which may improve the sealing performance of the connection between the transmission tube and the housing 11, reduce the situation that gas or filler flows out of the transmission tube, and after the splicing operation of the refrigeration device is completed, since most of the transmission tube is located in the gap of the refrigeration unit, the influence on the appearance of the refrigeration device is less, and after the part of the transmission tube exposed outside the gap is removed, the rest of the transmission tube may be left in the gap.

In some embodiments, as shown in fig. 1, the transfer tube may be in a detachable connection with the housing 11, and the connection end of the transfer tube and the housing 11 near the injection port 30 may be in a threaded connection, an interference connection, or the like.
