[0047] In order to prevent viruses from invading the human body, various sterilization devices appear on the market, among which sterilization lamps are widely used in the medical field. The sterilization lamp mainly sterilizes by emitting UVC ultraviolet light to harm biological cells and reduce the survival rate of biological cells. However, most of the current sterilization lamps adopt lamp tube type light emission, and the irradiation area is uncontrollable, so that the sterilization device irradiates one area for a long time to cause great harm to personnel biological cells.

[0048] The application discloses a sterilization device which can adjust the irradiation angle and make the irradiation area adjustable and easy to operate.

[0049] Please refer to Figure 1 and Figure 2 The embodiments of the application disclose a sterilization device, which comprises an irradiation module 100, a power control module 200, a rotating shaft 300 and a first limiting assembly 400. The power control module 200 is provided with a first through hole 211, the rotating shaft 300 is arranged on the irradiation module 100 and inserted into the first through hole 211, the power control module 200 and the irradiation module 100 are rotationally connected through the rotating shaft 300, and the first limiting assembly 400 is arranged in the power control module 200 and used for limiting the rotating shaft 300 from separating from the first through hole 211.

[0050] The irradiation module 100 is rotationally arranged on the power control module 200 through the rotating shaft 300, and the rotating shaft 300 is limited from separating from the first through hole 211 through the first limiting assembly 400, so that the irradiation module 100 can stably rotate on the power control module 200, the irradiation area of the sterilization device can be adjusted, and the operation is simple and stable.

[0051] Refer to Figure 2 In some embodiments, the rotating shaft 300 comprises a first connecting part 310, a second connecting part 320 and a third connecting part 330. The first connecting part 310 is fixedly arranged on the irradiation module 100, the second connecting part 320 is integrally formed with the first connecting part 310 and inserted into the first through hole 211, and the third connecting part 330 is integrally formed with the second connecting part 320 and connected with the first limiting assembly 400. The first limiting assembly 400 limits the third connecting part 330 to be fixed on the first limiting part 261 (refer toFigure 6 ) so that the rotating shaft 300 rotates stably.

[0052] The first connecting part 310, the second connecting part 320 and the third connecting part 330 are in cylindrical shape, the diameter of the first connecting part 310 is larger than that of the second connecting part 320 and the first through hole 211, the diameter of the third connecting part 330 is larger than that of the second connecting part 320 and the first through hole 211, the first connecting part 310 is located between the irradiation module 100 and the first through hole 211, the second connecting part 320 is inserted into the first through hole 211, and the third connecting part 330 is limited by the first limiting assembly 400 to move up and down. The diameter of the first connecting part 310 and the third connecting part 330 is larger than that of the first through hole 211, so that the irradiation module 100 rotates on the power control module 200 and does not fall off, and the third connecting part 330 is limited by the first limiting assembly 400, so that the irradiation module 100 rotates stably and prevents loosening when rotating.

[0053] In some embodiments, the first limiting assembly 400 comprises a first clamping piece 410 and an elastic sheet 420, the first clamping piece 410 is fixedly arranged on the inner top surface of the power control module 200, the elastic sheet 420 is clamped with the first clamping piece 410, the second through hole 421 into which the second connecting part 320 is inserted is arranged on the elastic sheet 420, and the second through hole 421 limits the third connecting part 330 from being separated.

[0054] The second through hole 421 is composed of a circular hole and a strip-shaped hole, the diameter of the circular hole is larger than that of the second connecting part 320, and the diameter of the circular hole is smaller than that of the third connecting part 330, and the second through hole 421 is located at the step position of the second connecting part 320 and the third connecting part 330, so that the rotating shaft 300 is limited to move up and down by the elastic sheet 420, and the irradiation module 100 rotates stably on the power control module 200. The strip-shaped hole has an opening, the second connecting part 320 is inserted into the circular hole along the opening of the strip-shaped hole, so that the elastic sheet 420 and the rotating shaft 300 are easy to install.

[0055] Please refer to Figure 2 and Figure 3 The first clamping piece 410 is arranged in plurality, in this embodiment, two first clamping pieces 410 are arranged and located at both ends of the first through hole 211. The first clamping piece 410 comprises a fixed part and a clamping part, the clamping part is integrally formed with the fixed part, and the shape of the first clamping piece 410 is inverted "L". The elastic sheet 420 is provided with a clamping groove 212 at both ends, the clamping part and the clamping groove 212 are matched to realize the connection between the elastic sheet 420 and the first clamping piece 410. The outer part of the first clamping piece 410 is in arc shape, so that when the elastic sheet 420 and the first clamping piece 410 are connected, the clamping piece is inserted into the clamping groove 212 easily.

[0056] In some embodiments, the protrusion on the elastic sheet 420 is provided with a support 422 abutting against the inner top surface of the irradiation module 100. In the present embodiment, two supports 422 are provided, and the two supports 422 are respectively located at the two ends of the second through hole 421. The provision of the two supports 422 at the two ends of the elastic sheet 420 balances the force at the two ends of the elastic sheet 420, and makes the elastic sheet 420 stably installed on the first clamping member 410, thereby making the rotation of the rotating shaft 300 on the elastic sheet 420 stable.

[0057] In the present embodiment, the support 422 is trapezoidal, and the support 422 comprises a support portion 424 and an abutting portion 425. The abutting portion 425 is horizontal to the inner top surface of the power control module 200, and the abutting portion 425 abuts against the inner top surface of the power control module 200. The abutting of the abutting portion 425 against the inner top surface of the power control module 200 makes the elastic sheet 420 horizontal and stable on the power control module 200. When the irradiation module 100 rotates, the rotating shaft 300 cannot move up and down along the first through hole 211, so that the rotating shaft 300 rotates stably, thereby making the irradiation module 100 rotate stably.

[0058] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the elastic sheet 420 is provided with a first limiting block 423 located close to the inner top surface of the power control module 200. The second limiting block 311 is protruded on the first connecting portion 310. When the rotating shaft 300 rotates to a certain angle along the first through hole 211 and the second through hole 421, the first limiting block 423 and the second limiting block 311 abut against each other. The abutment of the first limiting block 423 and the second limiting block 311 against each other blocks the continuous rotation of the rotating shaft 300, thereby limiting the rotation of the irradiation module 100 within a fixed rotation range.

[0059] In the present embodiment, the provision of the first limiting block 423 and the second limiting block 311 enables the irradiation module 100 to rotate within a range of -175° to 180°, so that the rotating shaft 300 rotates within a fixed range instead of 360°, thereby preventing the irradiation module 100 from being easily loosened due to 360° rotation.

[0060] Please refer to Figure 2 and Figure 5In some embodiments, a damping ring 340 is arranged on the rotating shaft 300, and the damping ring 340 is arranged between the first connecting part 310 and the second connecting part 320. By arranging the damping ring 340, the friction between the rotating shaft 300 and the power control module 200 is increased, so that the irradiation module 100 is not easy to return to the original position after being rotated to any angle, and the irradiation area of the sterilization device can be adjusted and stabilized.

[0061] With reference to Figure 5 In some embodiments, the irradiation module 100 comprises a first housing 110, a light cup 120, and an irradiation circuit board 130. The first housing 110 is provided with an opening, and the first housing 110 is fixedly connected with the rotating shaft 300. The light cup 120 is arranged in the first housing 110. The irradiation circuit board 130 is arranged between the light cup 120 and the first housing 110, and the irradiation circuit board 130 is used for emitting ultraviolet light. The light cup 120 is provided with a fifth through hole 122 at both ends, and the ultraviolet light emitted by the irradiation circuit board 130 is emitted through the fifth through hole 122 and the opening of the first housing 110.

[0062] The light cup 120 is in a conical shape. The conical light cup 120 can gather the ultraviolet light emitted by the irradiation circuit board 130 together and then emit the ultraviolet light through the fifth through hole 122, so as to improve the intensity of the ultraviolet light emitted by the sterilization device.

[0063] The first housing 110 is provided with a plurality of fixed columns 111. The light cup 120 is provided with a third through hole 121 around the periphery. The light cup 120 is composed of a cup-shaped body and a block-shaped body, and the third through hole 121 is arranged around the periphery of the cup-shaped body and the block-shaped body. Therefore, the third through hole 121 is arranged four on the cup-shaped body, and the third through hole 121 is also arranged four on the block-shaped body. One of the third through holes 121 on the block-shaped body is in a semi-opened form. The irradiation circuit board 130 is provided with a fourth through hole 131 around the periphery. The number of the third through holes 121, the fourth through holes 131, and the fixed columns 111 is the same. In this embodiment, the fixed columns 111 are arranged four, and the third through holes 121 and the fourth through holes 131 are also arranged four. Two of the fourth through holes 131 are in an opened form. The fixed columns 111 are inserted into the third through holes 121 and the fourth through holes 131, so as to fix the irradiation circuit board 130 and the light cup 120 in the first housing 110, thereby improving the stability of the irradiation circuit board 130 and the light cup 120 in the first housing 110.

[0064] The fixed column 111 is provided with a threaded groove, and the reflective cup 120 is provided with a screw threadedly connected with the fixed column 111. When the fixed column 111 is inserted into the third through hole 121 and the fourth through hole 131, the screw on the reflective cup 120 is inserted into the threaded groove and threadedly connected with the threaded groove, so as to fix the reflective cup 120 and the irradiation circuit board 130 in the first shell 110, thereby stably installing the reflective cup 120 and the irradiation circuit board 130 in the first shell 110.

[0065] The decorative cover 123 is arranged on the reflective cup 120 and covers the reflective cup 120. The decorative cover 123 has the same shape as the shape of the side of the reflective cup 120 away from the first shell 110. The decorative cover 123 covers the reflective cup 120 to cover the third through hole 121, so that the surface of the entire irradiation module 100 is smooth and beautiful.

[0068] The battery 230, the induction circuit board 240 and the control circuit board 250 are fixed in the second shell 210 by the second limiting assembly 260, so that the battery 230, the induction circuit board 240 and the control circuit board 250 are stably installed.

[0069] In some embodiments, the second shell 210 is provided with a clamping groove 212 on the inner side thereof; and the cover 220 is provided with a clamping assembly 270 inserted into the clamping groove 212.

[0070] The clamping grooves 212 are arranged in several numbers, four in the embodiment, and two clamping grooves 212 are arranged on each of the two inner sides of the second shell 210.

When it is needed to detach the cover 220 from the second shell 210, the cover 220 is directly opened, so as to realize the detachment of the cover 220 and the second shell 210 by separating the clamping block 272 from the clamping groove 212. Through the matching of the clamping block 272 and the clamping groove 212, the installation and detachment of the cover 220 and the second shell 210 are simple.

[0072] The second limiting assembly 260 comprises a first limiting piece 261, a second limiting piece 262, a third limiting piece 263, and a fourth limiting piece 264.
