For example, the other axial end of the inner sleeve 41 may be formed with a chamfer or a fillet. Therefore, when the mounting opening 301 is inserted into the sealing insertion groove 401, the other axial end of the inner sleeve 41 can be more easily inserted into the mounting opening 301, and the light-transmitting sleeve 30 can be more easily inserted into the sealing member 40, which is easy to operate.

The utility model discloses do not do special restriction to the concrete structure of ultraviolet lamp 10 and printing opacity sleeve pipe 30. Optionally, the ultraviolet lamp 10 extends in a shape of a long strip, a U-shape, a circle or an arc, and the light-transmitting sleeve 30 may extend in a shape of a long strip, a circle or a hemisphere, so that the ultraviolet sterilization module 100 can meet more use requirements.

For example, in the example shown in fig. 1 and 2, the ultraviolet lamp 10 is a U-shaped lamp, two end portions 11 of the U-shaped lamp are aligned, the light-transmitting sleeve 30 is an elongated tube, one axial end of the elongated tube is open to form the mounting opening 301, and the other axial end of the elongated tube is closed to form a closed end, which is advantageous for reducing the extending length of the first lead wire 21 or the second lead wire 22 inside the light-transmitting sleeve 30 while increasing the light emitting area of the ultraviolet lamp 10. In the example shown in fig. 3-4 and 8-11, the ultraviolet lamp 10 is an elongated lamp, the first wire connecting portion 121 and the second wire connecting portion 122 are respectively disposed at two axial ends of the elongated lamp, the light-transmitting sleeve 30 is an elongated tube, the two axial ends of the elongated tube are respectively opened to form two mounting openings 301, and the ultraviolet sterilization module 100 is substantially formed in an axisymmetric structure to facilitate mounting and fixing of the ultraviolet sterilization module 100 in the dishwasher. In the example shown in fig. 5 to 6 and 12 to 14, the ultraviolet lamp 10 is an elongated lamp, the first wire connecting portion 121 and the second wire connecting portion 122 are respectively disposed at two axial ends of the elongated lamp, the light-transmitting sleeve 30 is an elongated tube, one axial end of the elongated tube is open to form the mounting opening 301, and the other axial end of the elongated tube is closed to form a closed end, so that the ultraviolet sterilization module 100 has a simple structure and a small number of parts.

In some embodiments of the present invention, as shown in fig. 16 and 17, the ultraviolet sterilization module 100 may further include a fixing end 60, and the fixing end 60 is disposed in one-to-one correspondence with the sealing member 40. The fixing tip 60 may have a receptacle 601, and an axial end of the sealing member 40 may be inserted into the receptacle 601 to be fixed by the fixing tip 60. The hole diameter of the insertion hole 601 is D1, the outer diameter of at least one part of the sealing element 40 increases progressively along the direction from one axial end to the other axial end of the sealing element 40, the maximum outer diameter of the sealing element 40 is D2, the minimum outer diameter is D3, and D3 is not less than D1 and is less than D2.

Therefore, the sealing element 40 and the insertion hole 601 are matched to limit the sealing element 40 and the fixed end 60 along the axial direction of the sealing element 40, so that the sealing element 40 and the fixed end 60 are stably and reliably fixed, the insertion hole 601 can be in sealing contact with the outer peripheral surface of the sealing element 40, the fixed end 60 can shield and seal the lead 20 penetrating out of the sealing element 40, and the protruding part of the lead 20 is prevented from being damaged by high temperature or corroded due to contact with liquid or steam.

Optionally, as shown in fig. 16 and 17, the fixing terminal 60 may further have a wire passing hole 602 communicating with the insertion hole 601, and the lead wire 20 may be passed through the wire passing hole 602 to be connected to other structures such as a power supply.
