DETAILED DESCRIPTION

[0019] 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.

[0020] like Figure 1-5As shown, the utility model provides a desktop germicidal lamp, including a base 4, an end surface of the base 4 is provided with a support seat 6 which is perpendicular to and fixedly connected to the base 4, a rotating assembly is installed on the top of the support seat 6, and the rotating assembly includes a fixed seat 11, a rotating seat 8 rotatably installed on the fixed seat 11, and a lamp holder 7 fixedly installed on the rotating seat 8 and rotating with the rotating seat 8, a damping shaft 21 is provided between the rotating seat 8 and the fixed seat 11, and connecting pieces 18 are provided at both the front and rear ends of the damping shaft 21, and the damping shaft 21 is respectively fastened to the rotating seat 8 and the fixed seat 11 through the connecting pieces 18, and the rotating seat 8 is provided with a protective cover 1 connected to the rotating portion 22 at one end thereof, and the protective cover 1 wraps the lamp holder 7 inside thereof, and the rotating seat 8 is formed with a rotating part 22 at one end close to the fixed seat 11, and a limiting block 19 is formed on the outer edge of the rotating part 22. A movable groove 10 is opened in the middle of the fixed seat 11, and an arc groove 9 is opened on the outer edge of the fixed seat 11. The rotating part 22 is arranged inside the movable groove 10 and rotates with it. The limiting block 19 is arranged inside the arc groove 9 and slides with it. A power cord 5 is connected to one end of the base 4. The support seat 6 is connected to an H-type lamp tube 2 that can be sterilized after power is turned on. The H-type lamp tube 2 is connected to an electronic ballast connected to its drive. One end of the power cord 5 of the H-type lamp tube 2 is passed through the inside of the support seat 6 and passes through the middle of the damping shaft 21, and then connected to the H-type lamp tube 2. One end of the H-type lamp tube 2 is connected to the lamp holder 7 Therefore, in the process of rotating the H-shaped lamp tube 2, the rotating seat 8 rotates relative to the fixed seat 11. At this time, the limit block 19 slides along the arc groove 9 until the limit block 19 contacts the top groove wall of the arc groove 9, thereby limiting the rotation angle of the H-shaped lamp tube 2 to 180 degrees and realizing unidirectional rotation. This rotation method can effectively avoid the problem that the power cord 5 of the H-shaped lamp tube 2 is broken due to twisting, and the H-shaped lamp tube 2 will not change its angle under the action of the damping shaft 21. An ozone sheet 12 for generating ozone is provided inside the base 4, and a mounting seat for fixing the ozone sheet 12 is provided inside the base 4. A group of limit protrusions 14 are formed at both ends of the mounting seat, and a group of limit protrusions 14 have a gap between them to form The two ends of the ozone sheet 12 are respectively arranged inside the two limiting grooves, an air outlet 15 is provided on the side of the base 4 close to the ozone sheet 12, and an air inlet 16 is provided on the side of the base 4 away from the ozone sheet 12. A gasket 3 is provided at the bottom of the base 4, and the air inlet 16 and the air outlet 15 are both provided at the bottom of the base 4.
