Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of bathroom fixtures, and in particular to an ultraviolet light disinfection toilet seat with an irradiance indication window. Background Art
[0002] With the development of deep ultraviolet LED technology, miniaturized and integrated deep ultraviolet LED disinfection modules have made great progress. In the bathroom field, there is a normalized disinfection demand. The deep ultraviolet LED disinfection module can achieve the disinfection of bathroom products with limited space, such as toilets, thereby improving the quality of life of users. However, the current technology of deep ultraviolet LED chips still faces limitations. The prominent bottleneck is that there will be obvious luminous attenuation as the working time increases, resulting in insufficient irradiance of deep ultraviolet light and reduced disinfection effectiveness. Because deep ultraviolet light is invisible to the naked eye, and non-professionals who measure the irradiance of deep ultraviolet light may face the risk of deep ultraviolet light directly irradiating the human body, there is a certain risk of harm. Therefore, how to enable ordinary users to conveniently know whether the effectiveness of deep ultraviolet LED disinfection has been significantly attenuated has become a problem that needs to be solved. Utility Model Content
[0003] In view of this, the present invention provides an ultraviolet light disinfection toilet seat with an irradiance indication window, which at least partially solves the problems existing in the prior art.
[0004] A UV light disinfection toilet seat with an irradiance indication window is provided with a gasket and a cover plate. The gasket is provided with an opening and a ring-shaped portion. A deep ultraviolet LED is provided on the lower surface of the cover plate. The light output direction of the deep ultraviolet LED is toward the ring-shaped portion of the gasket. The cover plate is also provided with an indication window. The indication window is provided with a glass plate and a fluorescent plate. The glass plate is provided above the fluorescent plate. The indication window is provided above the ring-shaped portion. The width of the indication window is smaller than the width of the ring-shaped portion. Part of the light emitted from the deep ultraviolet LED toward the ring-shaped portion will be reflected by the upper surface of the ring-shaped portion and then emitted to the indication window, thereby exciting the fluorescent plate to emit fluorescence.
[0005] The light emission wavelength of the deep ultraviolet LED is less than 280 nm, and the deep ultraviolet light with a wavelength less than 280 nm does not pass through the glass plate.
[0006] The fluorescent plate is provided with fluorescent powder, which is Eu 2+ Doped BaMgAl 10 O 17 , or Ce 3+ With Tb 3+ Co-doped GdMgB5O 10 , or Ce 3+ With Tb 3+Co-doped Y2SiO5, or Ce 3+ With Tb 3+ Co-doped LaPO4, or Ce 3+ With Tb 3+ Co-doped MgAl 11 O 19 , or Eu 3+ Doped Y2O3.
[0007] The deep ultraviolet LEDs are arranged in an area corresponding to the circular portion.
[0008] The spacing between the deep ultraviolet LEDs is greater than the width of the deep ultraviolet LEDs.
[0009] There is a gap between the cover plate and the ring-shaped portion, and the thickness of the deep ultraviolet LED is smaller than the height of the gap.
[0010] The thickness of the glass plate and the thickness of the fluorescent plate are both smaller than the thickness of the cover plate.
[0011] The deep ultraviolet LED is welded on a circuit board, and the circuit board is mounted on the lower surface of the cover plate.
[0012] The deep ultraviolet LED is provided with lamp beads and a light-transmitting waterproof sealing cover. The light-transmitting waterproof sealing cover is a hollow hemispherical shell. The bottom of the light-transmitting waterproof sealing cover is bonded to the circuit board. The lamp beads are arranged inside the light-transmitting waterproof sealing cover. The light-transmitting waterproof sealing cover is made of quartz.
[0013] The glass plate is further provided with a low light transmittance portion.
[0014] Beneficial effects of the technical solution:
[0015] (1) Part of the light emitted from the deep ultraviolet LED to the ring-shaped portion will be reflected by the upper surface of the ring-shaped portion and then emitted to the indicator window, stimulating the fluorescent plate to emit fluorescence. The fluorescence can be projected onto the glass plate, so that the user can observe the fluorescence. However, the deep ultraviolet light does not pass through the glass plate, thereby protecting the user from potential harm caused by the deep ultraviolet light. The user can distinguish the attenuation of the irradiance provided by the deep ultraviolet LED from the intensity of the fluorescence, thereby judging whether the deep ultraviolet LED disinfection is still effective;
[0016] (2) The solution is simple and easy to implement, will not cause significant changes to the existing product structure, and is low cost;
[0017] (3) It only requires visual observation and is suitable for both young and old. No special instructions are required and it is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figures 1 to 3 A UV light disinfection toilet seat with an irradiance indication window is provided with a gasket 1 and a cover plate 2. The gasket 1 is provided with an opening and a ring-shaped portion. A deep ultraviolet LED 3 is provided on the lower surface of the cover plate 2. The light output direction of the deep ultraviolet LED 3 is toward the ring-shaped portion of the gasket 1. The cover plate 2 is also provided with an indication window 4. The indication window is provided with a glass plate 41 and a fluorescent plate 42. The glass plate 41 is provided above the fluorescent plate 42. The indication window 4 is provided above the ring-shaped portion. The width of the indication window 4 is smaller than the width of the ring-shaped portion. Part of the light emitted from the deep ultraviolet LED 3 to the ring-shaped portion will be reflected by the upper surface of the ring-shaped portion and then emitted to the indication window, exciting the fluorescent plate 42 to emit fluorescence.
[0029] The light emission wavelength of the deep ultraviolet LED 3 is less than 280 nm, and deep ultraviolet light with a wavelength less than 280 nm does not pass through the glass plate 41 .
[0030] The fluorescent plate 42 is provided with fluorescent powder, which is Eu 2+ Doped BaMgAl 10 O 17 , or Ce 3+ With Tb 3+ Co-doped GdMgB5O 10, or Ce 3+ With Tb 3+ Co-doped Y2SiO5, or Ce 3+ With Tb 3+ Co-doped LaPO4, or Ce 3+ With Tb 3+ Co-doped MgAl 11 O 19 , or Eu 3+ The phosphor is sandwiched between two upper and lower quartz plates to form a phosphor plate 42.
[0031] The deep ultraviolet LEDs 3 are arranged in the area corresponding to the circular portion.
[0032] The interval between the deep ultraviolet LEDs 3 is greater than the width of the deep ultraviolet LEDs 3 .
[0033] There is a gap 5 between the cover plate 2 and the ring-shaped portion, and the thickness of the deep ultraviolet LED 3 is smaller than the height of the gap 5 .
[0034] The thickness of the glass plate 41 and the thickness of the fluorescent plate 42 are both smaller than the thickness of the cover plate 2 .
[0035] The deep ultraviolet LED 3 is soldered on a circuit board, and the circuit board is mounted on the lower surface of the cover plate 2 .
[0036] The deep ultraviolet LED 3 is provided with a lamp bead and a light-transmitting waterproof sealing cover. The light-transmitting waterproof sealing cover is a hollow hemispherical shell. The bottom of the light-transmitting waterproof sealing cover is bonded to the circuit board. The lamp bead is arranged inside the light-transmitting waterproof sealing cover. The light-transmitting waterproof sealing cover is made of quartz. Example 2
[0037] like Figure 4 As shown, the glass plate 41 is further provided with a low-light-transmittance portion 6. This divides the fluorescence transmitted through the glass plate 41 into two regions: low brightness and high brightness. When the fluorescence brightness decreases significantly, the low-brightness region has low transmittance, making it difficult to observe the fluorescence. This facilitates the determination of deep ultraviolet light irradiance attenuation.
[0038] The rest is the same as that of the first embodiment.
[0039] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto.
