[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figures 1 to 4 As shown, a lamp holder assembly 1 comprises: a housing 11, a lamp board 12, a blocking plate 13, a light-transmitting plate 14 and a flange 15;

A blocking plate 13 is installed in one section of the shell 11 to form a heat dissipation cavity 19 between the blocking plate 13 and the partition 1101 .

[0039] The light board 12 is installed in the other section of the inner tube of the shell 11, and the back plate of the light board 12 is installed close to the other side of the partition 1101. The heat generated by the light board 12 is transferred to the partition 1101. In order to better achieve heat transfer, the partition 1101 is made of a metal material with excellent thermal conductivity. In order to prevent water from entering the light board 12, a light-transmitting plate 14 is arranged outside the light source of the light board 12, and a flange 15 is arranged outside the light-transmitting plate 14. The flange 15 is an annular flange, which is installed at the edge of the light-transmitting plate 14, and the ultraviolet light source generated by the light board 12 can pass through the middle of the flange 15.

[0040] The partition plate 1101 is provided with a first through hole 1105 , the flange 15 is provided with a second through hole 151 corresponding to the position of the first through hole 1105 , and the heat dissipation cavity 19 is in communication with the first through hole 1105 and the second through hole 151 .

[0041] Furthermore, a lamp board area 1102 is provided at the center of one side of the partition 1101 away from the heat dissipation cavity 19. The lamp board 12 includes a circuit board 121 and lamp beads 122. There are multiple lamp beads 122. The lamp beads 122 are UV LED lamps. The ultraviolet light source generated by them has a sterilization effect. The lamp beads 122 use special LED lamp beads. The heat generated by them can be effectively transferred to the circuit board 121. The circuit board uses an aluminum-based heat dissipation plate that is easy to dissipate heat. Multiple lamp beads 122 are installed on one side of the circuit board 121, and the other side of the circuit board 121 is installed close to the lamp board area 1102. In order to better achieve the heat dissipation effect, the contact surface between the circuit board 121 and the partition 1101 is coated with heat dissipation silicone grease.

[0042] Furthermore, a photosensitive element 123 is also provided on the circuit board 121, and the photosensitive element 123 is used to detect the ultraviolet intensity generated by the lamp bead 122. When the photosensitive element 123 detects that the surrounding ultraviolet intensity is lower than the set minimum intensity, the system determines that the lamp bead 122 is faulty.

[0043] Furthermore, a first truncated cone 1103 is provided on the periphery of the lamp board area 1102, the light-transmitting plate 14 is installed on the first truncated cone 1103, a sealing gasket 16 is provided between the first truncated cone 1103 and the light-transmitting plate 14, so as to seal the lamp board 12 in the lamp board area 1102, a second truncated cone 1104 is provided on the periphery of the first truncated cone 1103, a bolt hole 1106 is provided on the second truncated cone 1104, a flange 15 is installed on the second truncated cone 1104 by means of bolts 17, a sealing gasket 16 is provided between the flange 15 and the light-transmitting plate 14, so as to fix and seal the light-transmitting plate 14.

[0044] Furthermore, there are a plurality of first through holes 1105 , and the plurality of first through holes 1105 are evenly arranged along the circumference in the second truncated cone 1104 , and the flange 15 is provided with the same number of second through holes 151 as the number of the first through holes 1105 .

[0045] As a further embodiment of the present invention, one or more annular spoiler rings 1107 are provided on one side of the partition 1101 located at the heat dissipation cavity 19 , and the multiple spoiler rings 1107 are concentrically arranged.

[0046] Furthermore, an annular groove 1108 is provided on the outer circle of the housing 11 , and a first sealing ring 18 is provided in the groove 1108 .

[0047] A sterilization device comprises: a lamp holder assembly 1, an inner tube 2, an outer tube 3, a water inlet pipe 4, a water outlet pipe 5 and a second sealing ring 6. The lamp holder assembly 1 has two groups, which are respectively installed at the two ends of the inner tube 2. The outer tube 3 is sleeved on the outside of the inner tube 2. The second sealing ring 6 is arranged between the inner wall of the outer tube 3 and the outer wall of the inner tube 2. The water inlet pipe 4 and the water outlet pipe 5 are respectively connected to the lamp holder assembly 1 at both ends.

[0048] There are two ways to install the lamp holder assembly 1 at both ends of the sterilization device. One is a threaded connection. Specifically, a thread 1109 is also provided on the outer circle of the shell 11 away from the blocking plate 13, and threads are provided at both ends of the outer tube 3 and are respectively connected to the threads 1109 of the lamp holder assembly 1; the other way is to use flange installation. A mounting flange is provided on the outside of the shell 11, and mounting flanges are provided at both ends of the outer tube 3. The lamp holder assembly 1 is installed at both ends of the outer tube 3 by flange docking.

[0049] like Figure 7 As shown, as a specific embodiment, the water inlet pipe 4 and the water outlet pipe 5 are respectively connected to the heat dissipation cavity 19 of the lamp holder assembly 1 at both ends.

[0050] The specific working method is as follows Figure 8 As shown, holes are respectively opened on the plugging plates 13 of the lamp holder assemblies 1 on both sides, the water inlet pipe 4 is connected to the plugging plate 13 on one side, and the water outlet pipe 5 is connected to the plugging plate 13 on the other side. Water enters the heat dissipation cavity 19 of the lamp holder assembly 1 from the water inlet pipe 4, and the water contacts the partition 1101. The partition 1101 is made of metal material and can well transfer the heat generated by the lamp board 12. During the continuous contact between the water and the partition 1101, the heat generated by the lamp board 12 is taken away, thereby achieving heat dissipation of the lamp board 12. Since the partition 1101 is provided with first through holes 1105 around it, water passes through the partition 1101 along the first through holes 1105, and enters the inner tube 12 through the second through holes 151 on the flange 15. The lamp beads 122 on the lamp board 12 are UV LED lamps, and the lamp beads 122 generate ultraviolet rays. The ultraviolet rays pass through the light-transmitting plate 14 into the inner tube 12 and sterilize the water in the inner tube 12. Preferably, the inner wall or outer wall of the inner tube 12 may be provided with a reflective film or a reflective coating that reflects light inwardly, so that ultraviolet rays are continuously reflected in the inner tube to improve the sterilization efficiency. At the same time, the lamp holder assembly 1 connected to the water outlet pipe 5 also generates ultraviolet rays that are injected into the inner tube 12 to sterilize the water. The water continues to enter the lamp holder assembly 1 on the water outlet side from the inner tube 2, first passes through the flange 15, and enters the heat dissipation cavity 19 through the first through hole 1105. Through contact with the partition 1101, the lamp board 12 in the lamp holder assembly 1 is cooled again, and finally flows out from the water outlet pipe 5.

[0051] like Figure 5 As shown, as another specific embodiment, the water inlet pipe 4 and the water outlet pipe 5 are installed on the side wall of the outer tube 3, and an annular flow channel 21 is arranged between the two ends of the inner tube 2 and the outer circle, and the water inlet pipe 4 and the water outlet pipe 5 are respectively connected to the flow channels 21 at both ends, and the flow channel 21 is connected to the second through hole 151 of the lamp holder assembly 1.

[0052] The specific working method is as follows Figure 6 As shown, the water inlet pipe 4 is installed on the outer pipe 3 and communicated with the outer pipe. There is a flow channel 21 between the outer pipe 3 and the inner pipe. One side of the inner pipe 2 is against the end face of the bolt 17. Water enters from the water inlet pipe 4 and is divided into two parts after passing through the flow channel. One part directly enters the inner pipe 2, and the other part enters the heat dissipation cavity 19 through the second through hole 151 and the first through hole 1105. The water entering the heat dissipation cavity 19 returns to the inner pipe 2 again after contacting the partition 1101. The water enters the water outlet side through the inner pipe and is divided into two parts again. One part directly enters the water outlet pipe 5 through the flow channel 21, and the other part enters the heat dissipation cavity 19 through the second through hole 151 and the first through hole 1105. The water entering the heat dissipation cavity 19 returns to the flow channel 21 after contacting the partition 1101, and finally flows out through the water outlet pipe 5.

[0053] like Fig. 9As shown, as a further embodiment of the utility model, it also includes an electric control box 7 and a wire 8. The electric control box 7 is used to control the power output. The power input end of the electric control box 7 is connected to the external power supply through the wire 8. The output end of the electric control box 7 has two lamp boards 12 in the lamp holder assemblies 1 at both ends respectively connected through the wire 8.

[0054] In this embodiment, a method for managing the energy consumption of the light panel 12 is provided, specifically, when the water flow is relatively large, the light panels 12 on both sides can be controlled to work simultaneously to achieve a better sterilization effect. When the water flow in the inner pipe is small, only one side of the light panel 12 can be turned on for sterilization.

[0055] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
