Description

Technical Field

[0001] The invention relates to the technical field of fan installation, and in particular to a disinfection and sterilization device using optical sterilization. Background Art

[0002] The main function of the medical optical disinfection device is to use special light irradiation to achieve the purpose of disinfection. Common medical optical disinfection devices mainly include ultraviolet lamps.

[0003] In the prior art, the distance between the light emitting diode and the focusing lens is often kept constant by fixing them to each other through a first mounting mechanism and a second mounting mechanism, for example, by fixing screws. The focusing lens has a focal distance corresponding to a specific irradiation distance (i.e., the distance from the focusing lens to the irradiated object), and the focal point is aligned at a position corresponding to the specific irradiation distance. Therefore, by positioning the irradiated object at a position corresponding to the specific irradiation distance, the ultraviolet rays from the head are focused and irradiated on the irradiated object in an optimal irradiation state.

[0004] In such a conventional ultraviolet irradiation device, there is a problem that when the irradiation object is located at a position corresponding to an irradiation distance other than the specific irradiation distance, the ultraviolet rays from the head are irradiated on the irradiation object in a state deviated from the focus (i.e., a defocused state), resulting in a problem that irradiation cannot be performed in an optimal irradiation state.

[0005] In addition, the existing optical disinfection device often adopts a fixed structure when in use, that is, it is placed in a specific position for use. The light irradiation area and range of this method are fixed, and only specific positions and areas can be disinfected, which has great limitations. In addition, ultraviolet disinfection lamps are dangerous when in use, especially for the human body, which cannot be exposed to ultraviolet rays for a long time, otherwise it is easy to cause various adverse reactions. Therefore, the fixed structure in the prior art has great safety hazards.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0034] In this embodiment, the brightness changing assembly 5 includes a fixing member 51, a guide rail 52 and a sliding member 53. The sliding member 53 is slidably mounted on one side of the guide rail 52 relative to the fixing member 51. A mounting seat 54 is mounted inside the irradiation cavity 4. A load-bearing member 55 is connected and mounted on one side of the mounting seat 54. A controller 56 is fixed on one side of the load-bearing member 55. A first light focusing member 57 is mounted on one side of the sliding member 53. A second light focusing member 58 is mounted on one side of the fixing member 51. The first light focusing member 57 moves relative to the second light focusing member 58.

[0035] In this embodiment, the fixing assembly 6 includes a first clamping member 61, a second clamping member 62 and a two-way member 63;

[0036] In this embodiment, a bright component 7 is installed inside the irradiation cavity 4. The bright component 7 is composed of a UVLED that irradiates ultraviolet rays. The ultraviolet rays irradiated from the bright component 7 form a cylindrical light distribution. One side of the second clamping component 62 is a two-way convex structure. One side of the first clamping component 61 is provided with a mounting groove that is compatible with the two-way convex structure on one side of the second clamping component 62. The two-way component 63 is fixedly installed between the two-way convexities of the second clamping component 62 to fix and support the first clamping component 61. One side of the second clamping component 62 is fixedly installed with a first threaded component 64. The first threaded component 64 is connected to the second threaded component 62 through the second threaded component. The second threaded member 65 is connected and installed with one side of the second clamping member 62. A third clamping member 66 is fixed to one side of the second threaded member 65. The third clamping member 66 has the same structure as the second clamping member 62 and is fixedly installed between the second clamping member 62 and the first threaded member 64 in a staggered structure. A threaded portion is formed on the outer circumference of the bidirectional member 63 and the second threaded member 65, which is not shown in the figure. The fixing assembly 6 is preferably made of a metal with a relatively high thermal conductivity, such as aluminum. Through such a structure, the heat from the bright member 7 is transferred to the first threaded member 64 via the first clamping member 61, and the heat is dissipated via the first threaded member 64.

[0037] In this embodiment, the bright member 7 and the second light focusing member 58 and the first light focusing member 57 are in a vertical structure, the first light focusing member 57 and the second light focusing member 58 are in a convex mirror structure, and the focal lengths are not equal;

[0038] In this embodiment, a fixing assembly 6 is installed on one side of the controller 56, and the fixing assembly 6 fixes and supports the bright member 7. A locking member 59 is fixed on one side of the load-bearing member 55. The locking member 59 is a bidirectional convex structure. One side of the first focusing member 57 and the second focusing member 58 are respectively provided with grooves adapted to the two sides of the locking member 59, and the locking member 59 is made of a heat-conducting material.

[0039] In this embodiment, the first focusing member 57 and the second focusing member 58 are composed of a convex lens structure. First, the spacing distance between the bright member 7 and the first focusing member 57 is arbitrarily set, and the irradiation distance from the front end of the irradiation cavity 4 to the irradiation of ultraviolet rays is set to (for example, about 15 mm). Then, the controller 56 controls the power supply of the bright member 7, and the bright member 7 generates corresponding light. The ultraviolet rays irradiated by the bright member 7 form ultraviolet rays that expand into a cylindrical light distribution and are incident on one side of the first focusing member 57 for light diffraction. Under the action of the first focusing member 57, the ultraviolet rays are bent in the direction of the optical axis connected to the second focusing member 58. In the process of light movement, the ultraviolet rays emitted from the convex side of the first focusing member 57 are incident on the convex side of the second focusing member 58. Under the action of the second focusing member 58, the ultraviolet rays are bent in the direction closer to the outer optical axis of the second focusing member 58, and are emitted from the other side of the second focusing member 58. They are focused at the focal position on the optical axis set by the spacing distance between the bright member 7 and the first focusing member 57.

[0040] When the focal position is inconsistent with the position corresponding to the irradiation distance on the optical axis of the second focusing member 58, that is, the irradiation distance from the front end of the irradiation cavity 4 to the irradiation of the ultraviolet rays to the irradiation;

[0041] Further, a clamping member 501 is fixedly installed on one side of the fixing member 51, a first magnetic member 502 is fixed on the surface of one side of the clamping member 501, a limiting portion 503 is installed on one side of the clamping member 501, the clamping member 501 and one side of the limiting portion 503 are in contact with each other, a magnetic attraction source 504 is fixed on one side of the sliding member 53, a second magnetic member 505 is installed on one side of the magnetic attraction source 504, and the first magnetic member 502 and the second magnetic member 505 are magnet-shaped structures;

[0042] The polarities of the first magnetic member 502 and the second magnetic member 505 are opposite. When the second magnetic member 505 is powered on, the second magnetic member 505 generates a corresponding opposite force, thereby driving the magnetic source 504 to move in the same direction along the surface of the guide rail 52 and the direction of the bright member 7. Since one side of the magnetic source 504 is fixed to one side of the first light focusing member 57, the first light focusing member 57 is driven to move in the opposite direction relative to the second light focusing member 58.

[0043] The spacing distance between the bright part 7 and the first focusing part 57 is adjusted, thereby adjusting the focal position to a position corresponding to the irradiation distance on the optical axis, that is, the irradiation distance from the front end of the irradiation cavity 4 to the irradiation ultraviolet light to the irradiation. Thus, the focus is aligned with a position corresponding to the irradiation distance on the optical axis from the front end of the irradiation cavity 4 to the irradiation ultraviolet light to the irradiation. The ultraviolet light from the bright part 7 is focused and irradiated on the outside of the irradiation cavity 4, thereby irradiating in the optimal irradiation state.

[0044] When the irradiation distance is changed from the bright member 7 to the second focusing member 58 (for example, about 12 mm), the first focusing member 57 is set along Figure 2 The bright member 7 is moved in the direction shown, and the spacing distance between the bright member 7 and the second focusing member 58 is adjusted in the direction from the optical axis to the first focusing member 57 side.

[0045] In this embodiment, the polarity of the first magnetic member 502 is opposite to the polarity of the second magnetic member 505, the second magnetic member 505 is electrically connected to the controller 56, the second magnetic member 505 is rotatably installed on one side of the magnetic source 504, a temperature sensor is installed at the bottom of the fixing member 51, the output end of the temperature sensor corresponds to the center position of the second focusing member 58, and the temperature of the light emitted by the bright member 7 in the optimal irradiation state is monitored in real time to prevent the irradiated object from being damaged by ultraviolet rays due to long-term irradiation.
