Please refer to Figures 1 to 2, which is a preferred embodiment of the liquid sterilization device of the present invention, which includes: a container 1, a lifting component 2, a gate component 3, a sensing component 4, and a light source component 5 and a control component 6.

The container 1 has an accommodating space 11 inside, and the accommodating space 11 is used to store liquid L such as water, milk or juice. The container 1 can be composed of an upper surface 1a, a lower surface 1b, a top surface 1c, a bottom surface 1d and two side surfaces 1e, and thereby form the accommodation space 11, wherein the lower surface 1b, the bottom surface The surface roughness of the respective inner walls of 1d and the two side surfaces 1e is consistent and remains unchanged.

The container 1 has a baffle 12, which divides the accommodation space 11 into a buffer space 11a and a sterilization space 11b along the flow channel direction F. The flow channel direction F is such that the top surface 1c of the container 1 faces the The direction of the bottom surface 1d of the container 1.

Please refer to Figure 3 as well. The sterilization space 11b has the same cross-sectional area in the flow channel direction F, and has the same inclination angle θ relative to a virtual plane P, so that the liquid L is formed in the sterilization space 11b. A uniform flow that is maintained at a normal depth D (normal depth) and has a uniform-flow velocity. Its principle lies in the so-called "open-channel flow" in fluid mechanics. The flow depth of the liquid L in the flow channel direction F (ie, the above-mentioned normal water depth) does not change with distance under uniform conditions.

The baffle 12 is provided with a communication port 121 that connects the buffer space 11a and the sterilization space 11b. In this embodiment, the left and right ends of the baffle 12 are respectively in contact with the inner walls of the two side surfaces 1e. The baffle 12 The upper end is in contact with the inner wall of the upper surface 1a, and the communication port 121 is formed between the lower end of the baffle 12 and the inner wall of the lower surface 1b. Thereby, the liquid L can flow from the buffer space 11 a to the sterilization space 11 b via the communication port 121 along the flow channel direction F.

Furthermore, the container 1 has an input port 13 connected to the buffer space 11a, and an output port 14 connected to the sterilization space 11b. In this embodiment, the input port 13 is disposed closer to the top surface 1c. The upper surface 1a and the output port 14 are provided on the bottom surface 1d. Thereby, the liquid L can flow into the buffer space 11a through the input port 13, then enter the sterilization space 11b through the communication port 121, and finally flow out from the output port 14.

The lifting component 2 is combined with the container 1 and is used to control the inclination angle θ of the container 1 relative to the virtual plane P so that the liquid L can flow along the flow channel direction F. In this embodiment, the lifting assembly 2 has four height adjusters 21, which are respectively arranged at the four corners of the lower surface 1b of the container 1.

The gate assembly 3 has a first gate 31 , which is installed on the baffle 12 and used to open or close the communication port 121 . Preferably, the gate assembly 3 can also have a second gate 32, which is installed on the bottom surface 1d of the container 1 and used to open or close the output port 14.

In this embodiment, the sensing component 4 is a velocity meter. The sensing component 4 is installed in the sterilization space 11b and is used to detect the flow rate of the liquid L in the sterilization space 11b to obtain a flow rate value.

The light source assembly 5 has at least one sterilization lamp tube 51. The at least one sterilization lamp tube 51 is installed in the sterilization space 11b, and is preferably installed on the inner wall of the upper surface 1a of the container 1 to avoid contact with the sterilization process. Liquid L comes into contact. In this embodiment, the number of the at least one germicidal lamp tube 51 is two, each of the germicidal lamp tubes 51 is an ultraviolet lamp tube, and is used to emit ultraviolet light with a wavelength between 200 nanometers and 400 nanometers. This liquid L is sterilized.

The control component 6 can be disposed on the outer peripheral wall of the lower surface 1b of the container 1 and is electrically connected to the lifting component 2, the gate component 3, the sensing component 4 and the light source component 5. The control component 6 is used to operate the lifting component. The length of each of the four height adjusters 21 of the assembly 2 is used to adjust the inclination angle θ of the sterilization space 11b relative to the virtual plane P. The control component 6 controls the opening of the first gate 31 and obtains the flow rate value from the sensing component 4 .

The control component 6 calculates and obtains the normal water depth D of the liquid L based on the flow rate value using an operation formula, and determines whether the normal water depth D is not higher than a depth value. If the determination result is yes, then controls the operation of the light source component 5. This liquid L is sterilized. Wherein, the depth value is relatively set according to the sterilization penetration ability of the at least one germicidal lamp 51, which can be understood by those with ordinary knowledge in the relevant fields of the present invention, and the calculation formula also belongs to the common knowledge in the relevant fields of the present invention. I won’t go into details here.

Following the above, if the judgment result is no, operate the length of each of the four height adjusters 21 again to readjust the inclination angle θ of the sterilization space 11b relative to the virtual plane P, or/and control the first gate 31. Open the size to reduce the flow rate of the liquid L until the normal water depth D of the liquid L is no higher than this depth value.

Specifically, the at least one water guiding member 7 has an infusion port 71 and a liquid outlet 72 that communicate with each other. The infusion port 71 is provided corresponding to the output port 14 of one of the liquid sterilization devices. The liquid outlet 72 is provided corresponding to the input port 13 of another liquid sterilization device. For example, but not limited to, the water guiding member 7 can be in the shape of a funnel. Thereby, the liquid L flowing out from the output port 14 of one of the liquid sterilization devices can flow to the input port 13 of the other liquid sterilization device through the water guide 7 .

Please refer to Figure 5, which is a second embodiment of the liquid sterilization equipment of the present invention. The difference from the above-mentioned first embodiment is that the at least two liquid sterilization devices are arranged at intervals and staggered in the longitudinal direction, and two adjacent ones are The output ports 14 of the liquid sterilizing device are respectively facing opposite directions to facilitate installation in an environment with a small space.
