Description

UV sterilization box structure

The present invention relates to ultraviolet sterilization equipment, in particular to an ultraviolet sterilization box structure.

At present, ultraviolet lamps (such as UV tubes or LEDs) are used in the market to sterilize fluids such as water or air and other fluids. The main setting method is to install the ultraviolet lamps on the inside or outside of the box and use a single flow channel. The design allows the fluid to be irradiated by ultraviolet rays; thereby, the ultraviolet rays are used to irradiate the liquid in the box for a certain period of time to achieve a sterilization effect.

In addition, in the current ultraviolet sterilization box structure, in order to extend the irradiation time, the flow channel is lengthened to increase the irradiation time, resulting in a large increase in volume. In addition, in order to increase the sterilization effect, the flow channel is flattened to reduce the irradiation distance, resulting in an increase in flow resistance and a decrease in flow rate.

In view of this, the inventor of the present invention focused on the above-mentioned prior art, and made great efforts to solve the above-mentioned problems, which became the goal of the present inventor's improvement.

One purpose of the present invention is to provide an ultraviolet sterilization box structure, which has the inlet and outlet ports on different sides of the box, and cooperates with the inner wall of the box to form a diversion structure, and uses the principle of inertia to make the inside of the box The fluid can generate a spiral flow, so as to stay in the cavity for a long time, and avoid the fluid last in, first out, to ensure that it can receive enough ultraviolet radiation; in addition, the cavity design of this creation can reduce the flow resistance of the system. Only a lower water inlet pressure is required to obtain sufficient flow, thereby achieving a better sterilization effect and sufficient flow, which increases the practicality of this creation.

In order to achieve the above objective, the present invention is an ultraviolet sterilization box structure, which includes a box body and an ultraviolet lamp module. The box has a circular cavity and an inflow port and an outflow port communicating with the circular cavity. The inner wall of the circular cavity is formed with an arc-shaped flow channel, and the inflow port is located on the bottom side of one side of the box and connected to the arc The flow outlet is located in the middle of the other side of the box body. The ultraviolet lamp module is arranged on one side of the box. The ultraviolet lamp module includes a circuit board, an ultraviolet LED electrically connected to the circuit board, and a light-transmitting element. The light-transmitting element covers the ultraviolet LED and makes the ultraviolet light emitted by the ultraviolet LED Can enter the circular cavity; where the external fluid enters the circular cavity from the inlet, and flows through the circular cavity in a spiral shape along the arc-shaped flow channel, and is irradiated by the ultraviolet light of the ultraviolet LED Then flow out from the outflow port.

Compared with the prior art, the ultraviolet sterilization box system of the present invention has the inlet and outlet on different sides of the box in a vertical manner. In addition, the box has a circular cavity and is located in the circular cavity. The wall is formed with an arc-shaped guide channel. According to this, the fluid flowing into the circular cavity from the side of the box will be guided by the arc-shaped guide channel, and use the principle of inertia to spiral and slowly move toward the circle. Flow in the inner direction of the cavity, and then squeeze the water inside the circular cavity, and finally accelerate to flow out from the outlet on the other side. According to this, the residence time of the fluid entering the inside of the box will be prolonged, avoiding the fluid last in, first out, and being uniformly and fully irradiated by the ultraviolet light of the ultraviolet LED, thereby achieving the sterilization effect and increasing the practicability of the present invention. Furthermore, the fluid of the UV sterilization box of the present invention flows into the cavity instead of a slender flow channel. Compared with the existing slender flow channel, the flow resistance of the system is increased and the practicability is reduced. The outflow volume of the UV sterilization box of the present invention Low, so it can reduce the requirements for structural strength and increase the practicality of use.

The detailed description and technical content of the present invention are described as follows in conjunction with the drawings. However, the drawings are only provided for reference and explanation, and are not intended to limit the present invention.

Please refer to FIGS. 1 to 3, which are respectively a three-dimensional exploded schematic diagram, a three-dimensional appearance schematic diagram, and a cross-sectional view of the ultraviolet sterilization box structure of the present invention. The present invention is an ultraviolet sterilization box structure 1, which includes a box 10 and an ultraviolet lamp module 20 combined with the box 10. Accordingly, the ultraviolet light emitted by the ultraviolet lamp module 20 will irradiate the fluid in the box 10 to achieve the effect of ultraviolet sterilization on the fluid in the box 10. A more detailed description of the structure of the ultraviolet sterilization box structure 1 is as follows.

The box body 10 has a circular cavity 11 and a first-rate inlet 12 and a first-rate outlet 13 communicating with the round cavity 11. An arc-shaped flow channel 14 is formed on an inner wall surface of the circular cavity 11. The inflow port 12 is located on the bottom side 101 of one side of the box body 10 and is connected to the arc-shaped flow guide 14. In addition, the outlet 13 is located at the middle position 102 on the other side of the box body 10.

It is worth noting that the arc-shaped guide channel 14 is arranged to taper toward the inner direction of the circular cavity 11 in a spiral shape. In addition, in an embodiment of the present invention, the outer shape of the box body 10 is substantially cylindrical.

The ultraviolet lamp module 20 is arranged on one side of the box body 10. The ultraviolet lamp module 20 includes a circuit board 21, an ultraviolet LED 22 electrically connected to the circuit board 21, and a light-transmitting element 23. The light-transmitting element 23 covers the ultraviolet LED 22 and enables the ultraviolet light emitted by the ultraviolet LED 22 to enter the circular cavity 11.

Specifically, the box body 10 is provided with a groove 111 at the bottom of the circular cavity 11, and the ultraviolet LED 22 is located in the groove 111. In addition, the light-transmitting element 23 is a light-transmitting plate, and the light-transmitting element 23 is fixed on a top of the groove 111 and covers the ultraviolet lamp module 20.

In this embodiment, preferably, the ultraviolet sterilization box 1 further includes a radiator 30. The heat sink 30 is combined with the box body 10 and abuts the circuit board 21 to provide heat dissipation for the circuit board 21.

In more detail, the heat sink 30 has an accommodating space 31. A heat-conducting block 32 is disposed in the accommodating space 31, and the circuit board 21 is disposed on the heat-conducting block 32. In addition, the heat sink is formed with a plurality of heat dissipation fins 33 on a side away from the box body. Accordingly, the heat generated by the ultraviolet lamp module 20 during operation can be dissipated through the conduction of the heat conducting block 32 and the heat dissipation fins 33.

When using the ultraviolet sterilization box of the present invention, external fluid enters the circular cavity 11 from the inlet 12, and flows through the circle slowly and spirally along the arc-shaped flow channel 14 using the principle of inertia. The inside of the cavity 11 is irradiated by the ultraviolet light of the ultraviolet LED 22 and then flows out from the outflow port 13.

It should be noted that after the external fluid flows from the circular cavity 11 through the inflow port 12 of the bottom side 101 on one side of the box body 10, at this time, the fluid velocity is fast and is guided by the arc-shaped guide channel 14. The inertia principle is used to squeeze the fluid inside the circular cavity 11 by spirally and slowly flowing toward the inner direction of the circular cavity 11. Finally, the squeezed fluid will accelerate out of the outlet 13 on the other side. According to this, the residence time of the fluid entering the inside of the box 10 will be prolonged, so that the fluid can have enough time to receive enough ultraviolet light to be uniformly and fully irradiated by the ultraviolet light of the ultraviolet LED 22, thereby achieving a sterilization effect. .
