[0042] A preferred embodiment is described below, and the present application is more clearly and completely illustrated in combination with the accompanying drawings.
[0043] The present embodiment provides a sterilization waterway plate 100, and the specific structure is shown in Figure 1 , Figure 2 and Figure 3 The sterilization waterway plate 100 comprises a waterway plate main body 1, the waterway plate main body 1 is formed as a whole by ultrasonic welding of a waterway plate front shell and a waterway plate back plate, and meanwhile, a plurality of passages 11 are arranged in the waterway plate main body 1 for water flow, so as to reduce the space occupation of the passages 11 and improve the neatness of the passages 11 by integrating the passages 11 in the waterway plate main body 1. In addition, the sterilization waterway plate 100 further comprises:
[0044] Flow guide part 2, the flow guide part 2 is arranged protruding from the side wall of the bending part of the passage 11;
[0045] The sterilization part 3 is communicated with the flow guide part 2, and the sterilization part 3 is used to emit ultraviolet light to the water flow at the bending part of the passage 11. The sterilization part 3 comprises an ultraviolet lamp 31 and a light guide plate 32. The ultraviolet lamp 31 is arranged on one side of the waterway plate body 1, and the ultraviolet light is incident into the passage 11 through the ultraviolet lamp 31 along the light guide plate 32. The passage 11 has at least a first branch 111 and a second branch 112. The first branch 111 is arranged close to the ultraviolet lamp 31, and the second branch 112 is arranged away from the ultraviolet lamp 31. The power of the ultraviolet lamp 31 in the first branch 111 is less than that in the second branch 112. Different power sterilization parts 3 are arranged in different functional branches, so that the manufacturing cost is correspondingly reduced, and the sterilization effect is ensured.
[0046] Specifically, the flow guide part 2 is arranged in the passage 11 and located on the side wall of the bending part of the passage 11, so as to guide the water flow at the bending part of the passage 11 and destroy the tension of the water flow at the bending part, so that the water flow does not accumulate to form a dead water area when passing through the bending part, and the flow efficiency of the water flow in the waterway plate body 1 is improved. In this embodiment, the passage 11 is a cylindrical pipeline. Of course, in other embodiments, the passage 11 can also be a rectangular pipeline or a pipeline with other shapes. The purpose is to reduce the formation of bacterial colonies by the protruding flow guide part 2, which will not be described in detail here.
[0047] In addition, the sterilization part 3 is arranged in this embodiment. The sterilization part 3 is communicated with the flow guide part 2, and the sterilization part 3 is used to emit ultraviolet light. The flow guide part 2 itself is light-transmitting, so that the ultraviolet light can be smoothly irradiated on the water flow. The ultraviolet light is the light used for sterilization in the prior art, so as to effectively sterilize the water flow at the bending part of the passage 11 by the ultraviolet light. The flow guide part 2 is a light-transmitting material in the prior art, for example, a plastic shell. Through the cooperation of the flow guide part 2 and the sterilization part 3, the water flow efficiency is improved, and the passage 11 in the waterway plate can be effectively sterilized, so as to ensure that the water flow passing through the waterway plate can also meet the concept of sterilizing the whole pipeline, reduce the bacterial colonies in the water flow, and improve the user experience. It can be understood that after sterilization at the bending part of the passage 11, the water flow at other positions in the remaining passage 11 has a faster flow rate and is not easy to produce bacterial colonies. Even if part of the bacterial colonies are produced, the water flow can be sterilized by the sterilization part 3 when passing through each bending part in turn.
[0048] As shown in the drawings, Figure 4 The flow guide part 2 is arranged on the opposite sides of the bending part of the passage 11.
[0049] Specifically, the flow guide part 2 is provided in plurality to improve the sterilization effect and the water flow tension destruction effect by increasing the number of flow guide parts 2. In the present embodiment, two flow guide parts 2 are taken as an example for illustration, but the number of flow guide parts 2 is not limited. The two flow guide parts 2 are arranged on the side walls on the opposite sides of the bend of the passage 11 in a symmetrical manner to destroy the water flow tension. The water flow is more uniform when the two flow guide parts 2 are arranged on the opposite sides of the bend of the passage 11 than when one flow guide part 2 is arranged on the side wall of the bend and the other flow guide part 2 is arranged on the bottom of the bend.
[0050] Of course, the flow guide part 2 can also be provided in three or four, and when the number of flow guide parts 2 is three or four, the flow guide part 2 is still arranged on the side walls on the opposite sides of the bend of the passage 11 to ensure the uniformity of the water flow after the water flow tension is destroyed.
[0051] In the present embodiment, the dimension of the flow guide part 2 protruding from the side wall of the bend of the passage 11 is 1-1.5 mm.
[0052] Specifically, the flow guide part 2 extends in the horizontal direction from the side wall of the bend of the passage 11, and the dimension of the end of the flow guide part 2 away from the passage 11 from the side wall of the bend of the passage 11 is 1-1.5 mm. By limiting the dimension of the flow guide part 2 protruding, the water flow resistance is avoided to be increased due to the excessively large dimension of the flow guide part 2.
[0053] In another embodiment, the end of the flow guide part 2 away from the side wall of the passage 11 is in an arc shape. The arc-shaped end is a rounded corner end formed by rounding the corner of the end in the prior art. Compared with the rectangular structure end with corners, on the one hand, the end of the arc-shaped structure can effectively destroy the water flow tension, and on the other hand, the end of the arc-shaped structure can uniformly guide the water flow to prevent the water flow from being turbulent.
[0054] In the present embodiment, the flow guide part 2 extends from the side wall of the bend of the passage 11 to all the side walls of the passage 11.
[0055] Specifically, in addition to the flow guide part 2 arranged on the side wall of the bend of the passage 11, the flow guide part 2 is also arranged in the remaining passage 11 and protrudes from the side wall of the passage 11. By increasing the extension dimension of the flow guide part 2 in the passage 11, the destruction effect of the water flow tension is improved. It can be understood that the flow guide part 2 arranged in the remaining passage 11 is integrally formed with the flow guide part 2 arranged on the side wall of the bend of the passage 11 to ensure the continuity of the water flow. When the sterilization part 3 is in communication with the flow guide part 2, the sterilization part 3 can emit ultraviolet light at various positions in the passage 11 to further improve the sterilization effect.
[0056] In the present embodiment, a water quality detector 4 is also arranged in the passage 11. The water quality detector 4 is electrically connected with the control board (not shown in the figure) of the waterway board main body 1, and the sterilization part 3 is electrically connected with the control board.
[0057] Specifically, the water quality detector 4 is inserted on the waterway board back plate, and the detection end of the water quality detector 4 extends into the passage 11 and contacts with the water flow. The water quality detector 4 is electrically connected with the control board, so that the control board is turned on according to the electric signal when the water flow has bacteria, and the sterilization part 3 is turned on in a targeted manner, which reduces the starting frequency of the sterilization part 3 compared with the continuous opening of the sterilization part 3, protects the service life of the sterilization part 3, and reduces the use cost.
[0058] It should be noted that the water quality detector 4 in the embodiment is a structure in the prior art, and its operation mode and connection mode with the control board are also connection modes in the prior art, which are not improved in the embodiment.
[0059] In the embodiment, the water quality detector 4 and the sterilization part 3 are arranged in the first branch 111 and the second branch 112, the water quality detector 4 is arranged in the branch for different functions, and the sterilization part 3 is started in a targeted manner, so that the manufacturing cost is reduced, and the sterilization effect is guaranteed.
[0060] Of course, the passage 11 can also include other branches, such as a branch in communication with the valve body and a branch in communication with the booster pump, so as to reduce the manufacturing cost by arranging sterilization parts 3 with different powers. It can be understood that the branches are not in communication with each other, so as to avoid that the water flow in a branch has bacteria and pollutes other branches.
[0061] In the embodiment, the sterilization part 3 includes an ultraviolet lamp 31, the ultraviolet lamp 31 is arranged in the flow guide part 2, and the flow guide part 2 is made of transparent material.
[0062] Specifically, the flow guide part 2 is a shell protruding from the side wall of the passage 11, the shell is made of transparent material, such as a plastic shell or a glass shell, and the ultraviolet lamp 31 is arranged in the shell to emit ultraviolet light when turned on, so that the sterilization part 3 emits ultraviolet light into the passage 11 through the flow guide part 2.
[0063] Further, in the embodiment, the light guide plate 32 is used to guide the light of the ultraviolet lamp 31 into the passage 11, the light guide plate 32 is slightly larger than the size of the passage 11 and consistent with the extension path of the passage 11. It can be understood that the slightly larger is that the side edge of the light guide plate 32 extends into the passage 11, and the distance between the extending end and the side wall of the passage 11 is 1-1.5 mm. The light emitting end of the ultraviolet lamp 31 is in communication with the light guide plate 32, so as to reduce the number of ultraviolet lamps 31 arranged and guarantee the effective sterilization of the water flow in the passage 11 by the light guide plate 32.
[0064] The embodiment also provides a water purifier, which comprises the sterilization waterway board 100.
[0065] Specifically, the water purifier comprises the sterilization waterway board 100, and the sterilization waterway board 100 can sterilize the water flow, so that the water flow flowing through the waterway board is kept in a sterile state, and thus, when the pipelines of other structures of the water purifier can also sterilize the water flow, the water quality of the water flow in each structure of the water purifier is effectively sterilized, that is, the whole-pipeline sterilization concept is realized, and the situation that the user's use experience is reduced due to the fact that the bacterial count of some parts exceeds the standard is avoided.
[0066] Although the specific embodiments of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the utility model, and these changes and modifications all fall within the protection scope of the utility model.
