The present disclosure will be further described in detail below with reference to the drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the disclosure, and the words "embodiments" used in the present disclosure are intended to be used as examples, examples, or illustrations. In addition, the articles "a" or "an" or "an"

The reason why UV light can be sterilized is that the DNA or RNA of the microorganism is destroyed by UV irradiation, and the metabolism and inheritance of the microorganism are destroyed and killed. In general, the UV light that can be used for sterilization has a wavelength of about 265 nm. Generally, the UV lamp emits a large spectral range, and the intensity at this wavelength is too weak, and it is difficult to achieve the sterilization effect, and is applied to a three-dimensional article. When the irradiation is performed, it is easy to have a sterilization dead angle.

In order to avoid the absence of the UV lamp, the ultraviolet sterilization device of the present disclosure uses a UV point source for sterilization. The UV point source can be implemented by a UVC-LED (light emitting diode). In a broad sense, it emits ultraviolet light between 100 nm and 280 nm. UVC-LED can also emit UV light with a fairly narrow spectral range. The wavelength is concentrated at about 265 nm. Under the irradiation distance of 10 mm and the input power of ^1.2 W, it can reach 25 mW/cm ² . Compared to UV lamps, UVC-LEDs have a high bactericidal power and can achieve 99.99% disinfection in just a few seconds.

Please refer to FIG. 1 and FIG. 2, which shows a schematic view of an ultraviolet ray sterilizing apparatus according to an embodiment of the present disclosure, and FIG. 2 shows another view of the ultraviolet ray sterilizing apparatus of FIG.

The ultraviolet sterilization device of the present disclosure comprises a case 11 and a door 12. The casing 11 defines an opening 13 on one side, and the door 12 is disposed at a position corresponding to the opening 13 of the casing 11. The door 12 is operable in an open state and a closed state in which the door 12 shields the opening 13 of the casing 11 and, in the open state, exposes the opening 13 of the casing 12. For example, the door 12 is pivotally coupled to the case 11 and is pivotable to an open position and an closed position.

The cabinet 11 defines an accommodation space for accommodating an item. That is, the accommodating space can accommodate items to be sterilized, such as baby products, such as bottles, pacifiers, toys, and the like. When the door 12 is operated in the open state, the user can place the article into the case 11; when the door 12 is operated in the closed state, the article can be sterilized. After the sterilization is completed, the door 12 is opened and the article is taken out.

As shown in FIG. 2, the ultraviolet ray sterilizing apparatus of the present disclosure further includes a mounting board 14 and a plurality of UV point light sources 15, which are distributed on the mounting board 14. These UV point light sources 15 are used to emit ultraviolet rays to sterilize articles placed in the casing 11.

The mounting plate 14 and the UV point source 15 thereon can be disposed at any suitable location within the housing 11. Preferably, the mounting plate 14 can be disposed on one of the top faces 16 of the case 11. The UV point source 15 can also be disposed on the side of a bottom surface 17 of the case. Alternatively, as shown in Figs. 1 and 2, a UV point source 15 is disposed on both the top surface 16 and the bottom surface 17 of the casing 11, so that the UV point source 15 on the top surface 16 can illuminate the article. In the half, the UV point source 15 on the bottom surface 16 can illuminate the lower half of the article so that the ultraviolet rays completely illuminate the article, and the sterilization dead angle can be reduced.

Furthermore, the mounting plate 14 can be rotated by a rotating mechanism (described in detail later), and when the mounting plate 14 is rotated, the UV point source 15 thereon is rotated. Thus, the UV point source 15 can change its illumination position so that the area where the original light intensity is weak can be improved. On the other hand, the approach thus achieved can also reduce the number of UV point sources 15, without having to configure too many UV point sources 15, reducing cost and power consumption.

The mounting plate 14 can be directly driven to rotate by the rotating mechanism. A transmission mechanism or other intermediate structure may also be provided between the mounting plate 14 and the rotating mechanism to drive the rotation of the mounting plate 14.

The rotation of the mounting plate 14 and the UV point source 15 thereon can be realized on the top surface 16 of the casing 11. Of course, the mounting plate 14 disposed on the bottom surface 17 of the casing 11 may be rotated, or the mounting plate 14 of the top surface 16 and the bottom surface 17 may be rotated. These various embodiments are intended to be within the scope of the present disclosure.

As shown in Figures 1 and 2, the ultraviolet sterilization device of the present disclosure further includes a fixed grid 18 and a pivotable grid 19, and the fixed grid 18 and the pivotable grid 19 can be stainless steel grids. Used to carry the item. That is, items can be placed on these shelves 18 and 19 for sterilization.

The fixed grid 18 is disposed on the bottom surface 17 inside the casing 11. As shown in Fig. 1, the fixed grid 18 can be placed above the UV point source 15 below. Thus, the ultraviolet rays emitted from the lower UV point source 15 can be irradiated to the lower half of the article.

The pivotable grid 19 is disposed on a side 20 of the interior of the casing 11. In use, the pivotable grid 19 can be pivoted to a horizontal position (as shown in Figures 1 and 2) for placement of the item. Referring to Figure 3, the pivotable grid 19 can be pivoted to a vertical position (as shown in Figure 3) when not in use, i.e., in a position that conforms to the side 20. In this way, the pivotable grid 19 can be folded so that larger items can be placed on the fixed grid 18 for sterilization.

Figure 3 is a schematic view showing the height of an adjustable UV point source in an ultraviolet sterilization device according to an embodiment of the present disclosure.

Please refer to FIG. 2 together with reference to FIG. 3 . The ultraviolet sterilizing device of the present disclosure may further comprise a lifting mechanism (described in detail later) which is mounted together with the mounting plate 14 and can be used to adjust the height of the mounting plate 14 . Thereby adjusting the height of the UV point source 15. As shown in FIG. 2, when the lifting mechanism is housed, the UV point source 15 is at a first height; as shown in FIG. 3, when the lifting mechanism is actuated, the UV point source 15 is at a second position. height. The first height is greater than the second height. That is to say, when the lifting mechanism is actuated, the height of the UV point source 15 is lowered. Thus, if the height of the article is low, sufficient height of the UV point source 15 can be adjusted to provide sufficient illumination intensity.

The ultraviolet sterilization device of the present disclosure may further include a distance measuring module 21. The ranging module 21 can be, for example, an ultrasonic ranging module. The distance measuring module 21 is disposed on the mounting plate 14 for sensing the height of the articles disposed inside the casing 11. The lifting mechanism can adjust the height position of the mounting plate 14 according to the height sensed by the distance measuring module 21, thereby adjusting the height of the UV point source 15 thereon.

In a specific implementation, the user can manually actuate the lifting mechanism to adjust the height of the UV point source 15. Through the setting of the distance measuring module 21, the height adjustment of the UV point source 15 can also be fully automatic. That is to say, the user simply senses the height of the article by placing the article in the casing 11, and notifies the lifting mechanism to adjust the UV point source 15 to an appropriate height.

The lifting mechanism can be disposed on the top surface 16 , the bottom surface 17 or the top surface 16 and the bottom surface 17 of the box body 11 , that is, the UV point light source 15 which can be located on the top surface 16 , the bottom surface 17 or both can be realized. Height adjustment.

Please refer to Figure 4, Figure 5A and Figure 5B. 4 is a schematic view showing an elevating mechanism in an ultraviolet ray sterilizing apparatus according to an embodiment of the present disclosure, and FIG. 5A is a schematic view showing a UV point light source at a first height in an ultraviolet sterilizing apparatus according to an embodiment of the present disclosure, and FIG. 5B is a view showing In the ultraviolet sterilization device of the embodiment of the present disclosure, the UV point source is at a second height.

The rotating mechanism can include a first motor 22 and a turntable 23, and the first motor 22 can drive the turntable 23 to rotate. The lifting mechanism is fixed to the turntable 23 and mounted to the mounting plate 14. When the turntable 23 rotates, the lifting mechanism also rotates, thereby causing the mounting plate 14 to rotate, and the UV point source 15 thereon also rotates.

The lifting mechanism can include a second motor 24, a rotating rod 25, a moving member 26, a first bracket 27, a second bracket 28, a third bracket 29 and a fourth bracket 30. The rotating lever 25 is coupled to a rotating shaft of the second motor 24, and an outer thread 31 is disposed on the outer surface of the rotating lever 25 along its longitudinal direction. The moving member 26 defines an opening, and an internal thread is disposed on the surface of the opening. The rotating rod 25 passes through the opening of the moving member 26, and the external thread 31 of the rotating rod 25 and the internal thread of the opening of the moving member 26 are in mesh with each other.

Therefore, when the second motor 24 rotates, the moving member 26 is moved along the longitudinal direction of the rotating lever 25 due to the engagement of the internal and external threads. When the second motor 24 rotates in the first direction, the moving member 26 can move in a forward direction; when the second motor 24 rotates in a second direction opposite to the first direction, the moving member 26 can follow a retreating direction mobile.

One end of the first bracket 27 is pivotally connected to one end of the moving member 26, and the other end of the first bracket 27 is pivotally connected to the mounting plate 14 through a fixing block 32 fixed to the mounting plate 14. Similarly, one end of the third bracket 29 is pivotally connected to the other end of the moving member 26, and the other end of the third bracket 29 is pivotally connected to the mounting plate 14 through a fixing block (not shown) fixed to the mounting board 14.

One end of the second bracket 28 is pivotally connected to the turntable 23 via a fixing block 33 fixed to the turntable 23, and the other end of the second bracket 28 is pivotally connected to the mounting board 14 via a fixing block 34 fixed to the mounting board 14. Similarly, one end of the fourth bracket 30 is pivotally connected to the turntable 23 through a fixing block (not labeled) fixed to the turntable 23, and the other end of the fourth bracket 30 is transmitted through a fixing block (not shown) fixed to the mounting board 14. It is pivotally connected to the mounting plate 14.

The first bracket 27 and the second bracket 28 are pivotally connected to each other at a middle position thereof, and the third bracket 29 and the fourth bracket 30 are pivotally connected to each other at a middle position thereof. That is, the first bracket 27 and the second bracket 28 are pivotable at their intermediate positions, and the third bracket 29 and the fourth bracket 30 are pivotable at their intermediate positions.

In this embodiment, four brackets, that is, the first bracket 27, the second bracket 28, the third bracket 29, and the fourth bracket 30 are provided, which can increase stability. In other embodiments, only one set of brackets may be provided, such as the first bracket 27 and the second bracket 28, or the third bracket 29 and the fourth bracket 30.

Thus, when the moving member 26 moves in the forward direction, the first bracket 27 and the third bracket 29 are pivoted, and the second bracket 28 and the fourth bracket 30 are also pivoted together, so that the height of the mounting plate 14 is lowered. As shown in Figure 5B. When the moving member 26 moves in the backward direction, the first bracket 27 and the third bracket 29 are pivoted, and the second bracket 28 and the fourth bracket 30 are also pivoted together, so that the height of the mounting plate 14 rises, as in the first Figure 5A shows.

Thus, the lifting mechanism achieves height adjustment of the mounting plate 14 and the UV point source 15 thereon.

On the other hand, as shown in FIG. 1, the ultraviolet ray sterilizing apparatus of the present disclosure further includes a first switch 35 and a second switch 36 which are disposed on the outer surface of the casing 11. The first switch 35 is a power switch for turning on the power. The second switch 36 is an actuated switch that is used to initiate the entire sterilization process.

In the ultraviolet ray sterilizing apparatus of the present disclosure, the rotation of the mounting plate and the UV point light source distributed thereon can be realized by the rotating mechanism, thereby reducing the irradiation dead angle and reducing the number of UV point light sources. Furthermore, the lifting mechanism can achieve a height adjustment of the UV point source to provide sufficient illumination intensity. Moreover, the distance measuring module is used to sense the height of the article, and cooperates with the lifting mechanism to realize automatic adjustment of the height of the UV point source, thereby realizing automatic sterilization.

In an embodiment, only the lifting mechanism may be provided instead of the rotating mechanism.

Please refer to FIG. 6 , which shows a flow chart of a method of controlling an ultraviolet sterilization device according to an embodiment of the present disclosure.

Please refer to Figure 6 to Figure 6 together. The control method includes the following steps:

Step S62: Sensing the height of the item disposed in the accommodating space of the box. In this step, the height of the article placed inside the casing 11 is sensed by the distance measuring module 21 provided on the mounting plate 14, such as a bottle and a toy, which is an article to be sterilized.

Step S64: adjusting the height position of the mounting board according to the sensed height. In this step, the lifting mechanism adjusts the height position of the mounting plate 14 according to the height sensed by the ranging module 21, thereby adjusting the height of the UV point source 15 thereon. Here, the second motor 24 can be actuated such that the moving member 26 moves in the forward or backward direction, thereby lowering or raising the height of the mounting plate 14.

Step S66: rotating the mounting plate to rotate the UV point light sources distributed on the mounting plate. In this step, the first motor 22 rotates to drive the elevating mechanism to rotate, thereby rotating the mounting plate 14, and the UV point source 15 on the mounting plate 14 is also rotated.

For specific details of the control method, reference may be made to the above description of the ultraviolet sterilization device, which will not be described herein for the sake of brevity.

Fig. 7 shows an improvement of the above ultraviolet sterilizing apparatus, and Fig. 8 shows a block diagram of the ultraviolet sterilizing apparatus of Fig. 7. Please refer to FIG. 7 and FIG. 8 together. The door 12 can be provided with an observation window 37. The user can understand the sterilization operation in the box 11 through the observation window 37. The observation window 37 can be made of glass material. A filter can be added to the glass to reduce the intensity of the emitted UV light.

At the beginning of the sterilization operation, the controller 80 controls the ranging module 21 to detect the current height, that is, the distance between the distance measuring module 21 and the item to be sterilized, and decide whether to adjust the height. When yes, the controller 80 then controls the height adjustment module 83 to adjust the height of the UV point source 15, and the height adjustment module 83 controls the above-described lifting mechanism to adjust the height. When adjusted to the desired height, the controller 80 controls the ultraviolet module 84 so that the UV point source 15 emits ultraviolet light for sterilization.

Since the articles to be sterilized are usually washed with water and then sterilized by ultraviolet rays, in the sterilizing process, the hot air drying method may be used to air-dry the articles to be sterilized. That is, the controller 80 can control the hot air module 85 to perform hot air drying during the sterilization process. Correspondingly, the box 11 is provided with a third switch 38, which is a hot air drying switch. When it is opened, the hot air module 85 operates to dry the residue to be sterilized. Correspondingly, a first opening 39 and a second opening 40 are defined in the casing 11 . The first opening 39 is an air inlet, and the hot air generated by the hot air module 85 enters the casing 11 from the first opening 39. The second opening 40 is an air outlet or a water discharge opening. The air inlet and the air outlet are arranged to form a stable airflow in the casing 11, and the water remaining on the object to be sterilized is taken away, and the water is also discharged through the opening 40.

When the sterilization operation is in progress, the controller 80 notifies the alert module 86 to turn on the warning light 41.

The ultraviolet sterilization device is further provided with a timer 81, and the controller 80 controls the timer 81 to activate the timing function to control the operation of the ultraviolet module 84 and/or the hot air module 85.

A door switch detector 82 is disposed between the door 12 and the casing 11 for detecting whether the door 12 is open or closed. The door switch detector 82 is coupled to the controller 80 to transmit the detected open/close state of the door 12 to the controller 80. When the sterilization operation is in progress and the door switch detector 82 detects that the door 12 is opened. The controller 80 interrupts the operation of the ultraviolet module 84 and the hot air module 85. When the door switch detector 82 detects that the door 12 is in the closed state, the controller 80 allows the operation of the ultraviolet module 84 and the hot air module 85. That is to say, when the sterilization operation is in progress, when the door 12 is suddenly opened, the sterilization operation is suspended to avoid the risk of ultraviolet exposure. Moreover, the system allows sterilization only when the door 12 is closed.

Referring to Figures 9A and 9B, in the improvement of the lifting mechanism, one end of the bracket is moved on the sliding rail, which makes the entire operating system more stable and reduces the resistance.

Specifically, a first slide rail 91 and a second slide rail 92 are fixedly disposed on the turntable 23 . One end of the first bracket 27 is pivotally connected to one end of the moving member 26 and is connected with a protruding rod movable along the track hole of the first sliding rail 91. The other end of the first bracket 27 is transmitted through the fixing block fixed on the mounting plate 14. It is pivotally connected to the mounting plate 14. Similarly, one end of the third bracket 29 is pivotally connected to the other end of the moving member 26 and is connected with a protruding rod movable along the track hole of the second sliding rail 92, and the other end of the third bracket 29 is fixed to the mounting plate 14 through. The upper fixing block is pivotally connected to the mounting plate 14. When the protruding rods on the first bracket 27 slide on the track holes of the first sliding rail 91, the protruding rods on the third bracket 29 also slide in synchronization with the track holes of the second sliding rail 92.

Two slide rails, such as a third slide rail and a fourth slide rail, are also fixedly disposed on the mounting plate 14. One end of the second bracket 28 is pivotally connected to the turntable 23 through a fixing block fixed to the turntable 23, and the other end of the second bracket 28 is connected with a protruding rod movable along the track hole of the third slide rail. Similarly, one end of the fourth bracket 30 is pivotally connected to the turntable 23 through a fixing block fixed to the turntable 23, and the other end of the fourth bracket 30 is connected with a protruding rod movable along the track hole of the fourth slide rail. When the protruding rod on the second bracket 28 slides on the track hole of the third sliding rail, the protruding rod on the fourth bracket 30 also slides synchronously in the track hole of the fourth sliding rail.

The present disclosure has been disclosed in the above preferred embodiments. However, it is not intended to limit the scope of the disclosure, and various modifications and changes can be made without departing from the spirit and scope of the disclosure. Therefore, the scope of protection of this disclosure is subject to the definition of the scope of the patent application.
