Description

Built-in ultraviolet sterilization device

The invention relates to an air treatment device, in particular to a built-in ultraviolet sterilization device.

In the conventional technology, there are already many UV germicidal lamp devices that can be installed in offices or other artificial work spaces, and use ultraviolet irradiation to sterilize the work space. Since the ultraviolet rays projected by UV germicidal lamps can cause harm to the human body, the UV germicidal lamps must be turned off when there are people or animals in the room, and turned on when there are no people or animals.

However, the traditional frequent turning on and off of UV germicidal lamps will make operators very tired. If automatic operation is used to automatically turn on and off the UV germicidal lamp, on the one hand, the cost will be increased, and on the other hand, the life of the UV germicidal lamp will be reduced. In addition, indoor spaces often have people inside for a long time. If the UV germicidal lamp can only be turned on when no one is detected in the indoor space, the UV germicidal lamp will not be turned on most of the time. For example, during the daytime hours in the office, people are in the office most of the time, so the sterilization effect cannot be achieved.

This case hopes to propose a brand-new design that can still turn on the UV germicidal lamp for a long time when there are people in the indoor space, so as to achieve better sterilization effect and solve the above-mentioned previous technical shortcomings.

Therefore, the purpose of the present invention is to solve the above-mentioned problems in the conventional technology. The present invention proposes a A built-in ultraviolet sterilization device is formed into an air duct in a box. A UV germicidal lamp is installed inside the air duct. When the exhaust fan guides the air through the air duct, the UV germicidal lamp can be used to disinfect the passing air. After sterilization, it is discharged indoors. Since the UV germicidal lamp is arranged inside the air duct and will not illuminate the indoor space, even if there are people in the indoor space, the UV germicidal lamp can still be turned on for a long time, so the desired sterilization effect can be achieved. In this case, the functions of air duct exhaust and air inlet are integrated into one box, which can save volume and cost. And there is no need to manually switch the UV germicidal lamp on and off, making it very convenient to use. The air duct can be equipped with a windshield to form a flow channel, extending the flow path of the air, increasing the irradiation efficiency of the UV germicidal lamp, and achieving a better sterilization effect. The structure of this case is quite simple. There is no need to use a detector to detect people to automatically switch on and off the UV germicidal lamp, so it can save costs significantly. The windshield in this case can also be made of materials that allow ultraviolet rays to penetrate, which can increase the range of ultraviolet rays inside the air duct. In this case, a reflective layer can also be formed on the inner wall of the air duct to reflect ultraviolet rays to increase the utilization of ultraviolet rays. The box in this case can also be equipped with a wheel body and an automatic displacement module, which has an artificial intelligence learning function and can automatically drive the box to move to different positions for sterilization operations.

In order to achieve the above object, the present invention proposes a built-in ultraviolet sterilization device, which includes a box with an air duct for wind flow formed inside. The air duct includes two openings, namely a front opening and a rear opening; one of the two openings is One is used for air inlet and the other is used for exhaust; an exhaust fan is located inside the box and is used to guide the flow of air in the air duct; and at least one UV germicidal lamp is located inside the air duct. The inside of the duct is used to irradiate ultraviolet rays to kill bacteria in the air; the projection angle of the UV germicidal lamp must be such that the ultraviolet rays do not directly radiate to the outside of the front opening of the air duct.

Hereby, we would like to give a detailed description of the structural composition of this case, as well as the functions and advantages it can produce, together with the drawings, and give a detailed description of one of the preferred embodiments of this case as follows.

Please refer to Figures 1 to 13, which show the built-in ultraviolet sterilization device 5 of the present invention, which includes the following components:

A box 1 has an air duct 10 for wind flow inside. The air duct 10 includes two openings 11 , namely a front opening 111 and a rear opening 102 , as shown in Figure 1 . One of the two openings 11 is used for air inlet and the other is used for air exhaust, depending on the needs. Preferably, the front opening 111 is closer to the gathering place.

An exhaust fan 2 is located in the box 1 for guiding the flow of wind in the air duct 10 .

At least one UV germicidal lamp 20 is located in the air duct 10 for irradiating ultraviolet rays to kill bacteria in the air. The UV germicidal lamp 20 can be a general ultraviolet lamp 21 or an ultraviolet LED lamp 22. The UV germicidal lamp 20 may be in the form of a lamp tube 201 or a series of lamp beads 202. When the UV germicidal lamp 20 is in the form of a series of lamp beads 202, in order to have a better sterilization effect, it can be a row of lamps formed by a plurality of lamp beads 202 in series. The projection angle of the UV germicidal lamp 20 must be such that the ultraviolet rays do not directly radiate to the outside of the front opening 111 of the air duct 10 .

At least one windshield 30 is located inside the air duct 10, and a flow channel 40 is formed inside the air duct 10, as shown in Figure 2. One end of the flow channel 40 is located at one of the openings 11 of the air duct 10 , and the other end of the flow channel 40 is located at the other opening 11 of the air duct 10 . Therefore, the air can be flowed from the air along the flow channel 40 . One opening 11 of the air duct 10 flows to the other opening 11 . Overall, the path length of the air flowing in the air duct 10 can be extended. Moreover, a windshield 30 is arranged inside the air duct 10 to extend the flow channel 40, which can prevent the air outlet from being too large and causing insufficient residence time of the air in the air duct 10, thereby reducing the sterilization effect of the UV germicidal lamp 20.

The UV germicidal lamp 20 is located in the flow channel 40. Preferably, the at least one UV germicidal lamp 20 can be arranged along the flow channel 40, so as to achieve a better sterilization effect. When the windshield 30 is installed inside the air duct 10, it is preferred that the UV germicidal lamp 20 is not disposed close to the front opening 111 of the air duct 10 to prevent the UV germicidal lamp 20 from irradiating external air. personnel, so the UV germicidal lamp 20 can be turned on for a long time.

As shown in FIG. 6 , the at least one windshield 30 can form a curved flow channel 40 for several windshields 30 to extend the overall length of the flow channel 40 and configure multiple UV germicidal lamps 20 .

Using the above configuration, since the UV germicidal lamp 20 will not directly illuminate the front of the air duct 10 Opening 111 is external to personnel, so it will not harm personnel. Moreover, the UV germicidal lamp 20 can still be turned on and used when there are people. It will not cause the UV germicidal lamp 20 to be unusable when there are people around. If the UV germicidal lamp is used only when no one is around, the installation effect of the UV germicidal lamp will be poor.

Figures 2 to 6 show different configurations of the windshield 30 and the UV germicidal lamp 20. The arrows in the figures represent the air flow direction.

As shown in Figure 2, a windshield 30 and a UV germicidal lamp 20 are disposed inside the air duct 10. The UV germicidal lamp 20 is a general ultraviolet lamp 21 and is in the form of a lamp tube 201 (it can also be a lamp). The UV germicidal lamp 20 is perpendicular to the air flow direction in the air duct 10, so it can have a better sterilizing effect than without the windshield 30.

As shown in Figures 3 and 4, two windshields 30 and a UV germicidal lamp 20 are disposed inside the air duct 10. The UV germicidal lamp 20 is a general ultraviolet lamp 21 and is in the form of a lamp tube 201 ( It can also be a series of lamp beads). The UV germicidal lamp 20 is perpendicular to the air flow direction in the air duct 10. The use of two windshields 30 can extend the length of the flow channel 40. Therefore, compared with Figure 2 The configuration structure of Figure 3 and Figure 4 has better sterilization effect.

As shown in Figure 5, a windshield 30 and a UV germicidal lamp 20 are disposed inside the air duct 10. The UV germicidal lamp 20 is a general ultraviolet lamp 21 and is in the form of a lamp tube 201 (it can also be a lamp). The UV germicidal lamp 20 is parallel to the air flow direction in the air duct 10 and can have a larger irradiation cross-sectional area to achieve better sterilization effect.

As shown in Figure 6, four windshields 30 and a plurality of UV germicidal lamps 20 are arranged inside the air duct 10. The plurality of UV germicidal lamps 20 are arranged along the flow channel 40, and each UV germicidal lamp 20 is The ultraviolet LED lamp 22 is in the form of lamp beads 202 in series. Each UV germicidal lamp 20 is perpendicular to the air flow direction in the air duct 10. The arrangement of the lamp beads 202 of multiple UV germicidal lamps 20 has the following features: Better sterilization effect fruit.

When the UV germicidal lamp 20 is an ultraviolet LED lamp 22 and has lamp beads 202 in series, the lamp array 100 is composed of a plurality of lamp beads 202 in series. The arrangement is as shown in Figure 7 , in which each lamp bead is 202 has a specific irradiation range, so it must be arranged in an array to achieve the required irradiation intensity. Figure 8 shows that the angle between the irradiation range of each lamp bead 202 and the vertical direction is 70 degrees, so in this design case The illumination angle of the UV LED lamp must be considered.

As shown in FIG. 11 , preferably the windshield 30 is made of a material that allows ultraviolet rays to penetrate (such as glass, transparent materials or translucent materials, etc.), so that the ultraviolet rays 205 of the UV germicidal lamp 20 can penetrate the The windshield 30 irradiates other positions inside the air duct 10 to increase the irradiation range of ultraviolet rays. As shown in FIG. 11 , the ultraviolet ray 205 of the UV germicidal lamp 20 is represented by a dotted line.

As shown in Figure 12, preferably, the inner wall surface of the air duct 10 has a reflective layer 15, which is made of a material that can reflect ultraviolet rays. The reflective layer 15 is used to reflect the ultraviolet rays 205 of the UV germicidal lamp 20, so that the ultraviolet rays 205 After being reflected, the ultraviolet rays can continue to irradiate the inside of the air duct 10 , thereby improving the irradiation utilization rate of the ultraviolet rays in the air duct 10 . As shown in FIG. 12 , the ultraviolet ray 205 of the UV germicidal lamp 20 is represented by a dotted line.

An indicator light 50 is located on one side of the box 1 for displaying the operating status of the UV germicidal lamp 20 .

A control unit 60 is connected to the at least one UV germicidal lamp 20 (as shown in FIG. 9 ) and is used to control the starting period of the UV germicidal lamp 20 . Therefore, the UV germicidal lamp 20 can be turned on at a specific time, for example, the UV germicidal lamp 20 can be turned on from 30 minutes before work to the time after get off work.

Figure 13 shows another embodiment of the exhaust fan 2 of this case. The exhaust fan 2 is a fan 70 with blades 71 and is located at the front opening 111 of the air duct 10 to form an electric fan. Therefore, it has the function of strong air supply. The surface of the blade 71 of the fan 70 can also be rotated like a general electric fan to achieve a larger air supply range. That is, it integrates ultraviolet sterilization and electric fan functions.

The control unit 60 also includes a time control unit 61 for the user to control the startup time of the ultraviolet sterilization device 5. The time control unit 61 is also used for the user to set the startup sequence or set the schedule to match the personnel's needs. Work and rest, such as operating the ultraviolet sterilization device 5 before going to work or during lunch break to avoid affecting the personnel's work and rest.

The control unit 60 further includes a remote control unit 62 for signal communication with an external remote control 63 so that the remote control 63 can wirelessly control the ultraviolet sterilization device 5 remotely.

The bottom of the box 1 is connected with a plurality of wheels 80 , and the wheels 80 enable the box 1 to move.

As shown in Figure 10, this case also includes an automatic displacement module 90 connected to the plurality of wheels 80. The automatic displacement module 90 can drive the box 1 to automatically shift, so that the ultraviolet sterilization device 5 can be replaced at any time. Extensive area sterilization. This is because the air flow is often limited to certain areas, such as only in the living room, so if the ultraviolet sterilization device 5 is fixed in one area, its sterilization effect will also be limited to this area. If the ultraviolet sterilization device 5 is moved manually, it is quite time-consuming and labor-intensive, and it is also not in line with the operating habits of ordinary people.

In addition, the automatic displacement module 90 can perform artificial intelligence spatial movement learning, can learn the spatial distribution of the area and the residence time in different spaces, and store the learned data so that when the space is shifted, It can automatically move to different areas based on the learned data and stay for a predetermined period of time to perform sterilization operations.

The advantage of this case is that an air duct is formed in a box, and a UV germicidal lamp is installed inside the air duct. When the exhaust fan guides the air through the air duct, the UV germicidal lamp can sterilize the passing air and then discharge it into the air duct. Indoors, since the UV germicidal lamp is configured inside the air duct and will not illuminate the indoor space, even if there are people in the indoor space, the UV germicidal lamp can still be turned on continuously for a long time, so it can achieve the desired sterilization effect. This case integrates the functions of air duct exhaust and air inlet into one box, which can save Volume and cost. And there is no need to manually switch the UV germicidal lamp on and off, making it very convenient to use. The air duct can be equipped with a windshield to form a flow channel, extending the flow path of the air, increasing the irradiation efficiency of the UV germicidal lamp, and achieving a better sterilization effect. The structure of this case is quite simple. There is no need to use a detector to detect people to automatically switch on and off the UV germicidal lamp, so it can save costs significantly. The windshield in this case can also be made of materials that allow ultraviolet rays to penetrate, which can increase the range of ultraviolet rays inside the air duct. In this case, a reflective layer can also be formed on the inner wall of the air duct to reflect ultraviolet rays to increase the utilization of ultraviolet rays. The box in this case can also be equipped with a wheel body and an automatic displacement module, which has an artificial intelligence learning function and can automatically drive the box to move to different positions for sterilization operations.

To sum up, the humanized and considerate design of this case is quite in line with actual needs. Its specific improvement has the existing deficiencies, and it has obvious breakthrough advantages compared to the conventional technology, and it does have an improvement in efficacy, and it is not easy to achieve. This case has not been published or disclosed in domestic or foreign documents or markets, and it complies with the provisions of the patent law.

The above detailed description is a specific description of one possible embodiment of the present invention. However, this embodiment is not intended to limit the patent scope of the present invention.
