[0039] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0040] As mentioned in the background art, the existing fluid purifier has a complex purification module structure and low purification efficiency.

[0041] Based on this, the present application provides a fluid purification module and a fluid purification device, which uses light-conducting cotton as a sterilization component and cooperates with ultraviolet light to sterilize the fluid. Through a compact structural design, the structure is simplified while greatly improving the photocatalytic efficiency. It can achieve multiple cycles of sterilization without causing harm to the human body.

[0042] like Figure 1As shown, a fluid purification module in an embodiment of the present invention comprises a sterilization element 20, a light source group 30 and a filter element 40 which are sequentially arranged along a first direction (x direction in the figure).

[0043] The sterilization element 20 includes light-conducting cotton. The light-conducting cotton is located within the irradiation range of the light source group 30, and the light-conducting cotton can sterilize the fluid flowing through it under the irradiation of the light source group 30. The light-conducting cotton is composed of at least fibers and photocatalyst particles. Among them, the fibers are preferably glass fibers. The light-conducting cotton has a UV transmittance of 99%, which can promote the propagation of UV light in the air and water, and has a stronger disinfection ability. It can not only kill common pathogens in the fluid, but also has a strong disinfecting ability for difficult-to-inactivate pathogens, and can achieve multiple cycles of sterilization. It can still maintain the ability to sterilize and disinfect after multiple uses. At the same time, it has high chemical stability and is harmless to the human body.

[0044] The light source group 30 includes a first light source 31 and a second light source 32. The first light source 31 is used to emit ultraviolet light with a wavelength in a first band, and the wavelength range of the first band is 320nm-400nm. The second light source 32 is used to emit ultraviolet light with a wavelength in a second band, and the wavelength range of the second band is different from that of the first band, and the wavelength range of the second band is 200nm-290nm.

[0045] The filter element 40 is located on the side of the light source group 30 away from the sterilization element 20, and is used to filter the fluid flowing through the filter element 40. The filter element 40 includes a sponge sprayed with carbon mesh.

[0046] It is understandable that the fluid purification module further includes a housing 10. The sterilization element 20, the light source group 30 and the filter element 40 are all installed in the housing 10 to form a complete module structure.

[0047] refer to Figure 1 and Figure 2 As shown, the housing 10 includes a bottom plate 11, a first connecting plate 111 and a second connecting plate 112 disposed at opposite ends of the bottom plate 11, and a support plate 12 disposed above the bottom plate 11. A first space A is formed between the bottom plate 11 and the support plate 12, and the sterilizing element 20 is disposed in the first space A. The filter element 40 is disposed on the first connecting plate 111 and the second connecting plate 112. A second space B is formed between the filter element 40 and the support plate 12, and the light source group 30 is disposed in the second space B.

[0048] Exemplary, reference Figure 2 and Figure 3 As shown, an extension portion 113 facing the first direction (x direction shown in the figure) is provided at the edge of the base plate 11 between the first connecting plate 111 and the second connecting plate 112. The extension portion 113 is used to support and fix the support plate 12 so that a first space A for placing the optical conductive cotton is formed between the support plate 12 and the base plate 11.

[0049] In order to allow the fluid to flow through the light-conducting cotton in the first space A, a first window 114 is provided on the bottom plate 11, and the area ratio of the first window 114 to the bottom plate 11 is greater than or equal to 2 / 3. Preferably, the first window 114 is as large as possible to expose as much light-conducting cotton as possible.

[0050] A limiting net (not shown) is disposed on the first window 114, and the limiting net (not shown) can prevent the light-conducting cotton from escaping from the first space A under the action of the fluid.

[0051] In order to guide the fluid flowing through, the first connecting plate 111 is vertically arranged relative to the bottom plate 11, and the second connecting plate 112 is inclined relative to the bottom plate 11 in a first direction (x direction in the figure) away from the first connecting plate 111. This arrangement makes the straight-line distance between the two connecting plates gradually increase in the direction away from the bottom plate 11, and expand outward in a trumpet shape, thereby increasing the air output.

[0052] The first connecting plate 111 is provided with a first slot 1111, and the second connecting plate 112 is provided with a second slot 1121. The first slot 1111 and the second slot 1121 are arranged opposite to each other and have a certain distance from the bottom plate 11. The filter element 40 is arranged in the first slot 1111 and the second slot 1121.

[0053] refer to Figure 2 and Figure 4 As shown, the support plate 12 is disposed on the bottom plate 11, between the filter element 40 and the bottom plate 11, and between the first connecting plate 111 and the second connecting plate 112. A second space B is formed between the support plate 12 and the filter element 40.

[0054] The support plate 12 has a first end a corresponding to the first connecting plate 111, a second end b corresponding to the second connecting plate 112, and a third end c and a fourth end d adjacent to the first end a and the second end b. The third end c and the fourth end d of the support plate 12 extend in a direction close to the bottom plate 11 (opposite to the first direction) to form an air guide plate 121. The air guide plate 121 covers the extension portion 113 of the bottom plate 11 and is fixed to the extension portion 113 by a fastener. The fastener may preferably be a screw. The air guide plate 121 has a certain extension length to protrude from the surface of the bottom plate 11, and guide the fluid into the first window 114 and the first space A of the bottom plate 11.

[0055] In order to allow the fluid to flow out of the first space A through the light-conducting cotton in the first space A and into the second space B, a second window 122 is provided on the support plate 12, and the area ratio of the second window 122 to the support plate 12 is greater than or equal to 2 / 3. Preferably, the second window 122 is as large as possible to expose as much light-conducting cotton as possible.

[0056] In one embodiment, the second window 122 and the first window 114 are disposed correspondingly.

[0057] In yet another embodiment, the size of the first window 114 is the same as the size of the second window 122 .

[0058] Likewise, a limiting net (not shown) is disposed on the second window 122, and the limiting net (not shown) can prevent the light-conducting cotton from escaping from the first space A under the action of the fluid.

[0059] Due to the inclined setting of the second connecting plate 112 on the base plate 11, a distance is formed between the second connecting plate 112 and the second end b of the support plate 12. In order to better confine the optical cotton in the first space A, the second end b of the support plate 12 extends toward the base plate 11 to form a limiting portion 123, and the limiting portion 123 is used to limit the sterilization component 20 in the first space A.

[0060] At least one pair of ends of the support plate 12 extend away from the bottom plate 11 (in the first direction) to form a support portion 124 , on which the light source group 30 is disposed, and the light emitting direction of the light source group 30 is toward the space where the sterilization element 20 is located.

[0061] Exemplarily, the pair of ends may be the first end a and the second end b, or the third end c and the fourth end d, or the support portion 124 may be formed on the first end a, the second end b, the third end c, and the fourth end d.

[0062] A specific embodiment of the utility model further provides a fluid purification device, in which the above-mentioned fluid purification module is arranged, wherein the irradiation direction of the light source group of the fluid purification module is away from the fluid outlet direction of the fluid purification device.

[0063] Compared with the prior art, the fluid purification module and fluid purification device of the utility model have a simple structure, high photocatalytic efficiency, can achieve multiple cycles of sterilization, and will not cause harm to the human body.

[0064] The fluid purification module and fluid purification device of the utility model use light-conducting cotton as a sterilization component, and cooperate with ultraviolet light to achieve sterilization of the fluid.

It can not only kill common pathogens in the fluid, but also has a strong disinfecting ability for difficult-to-inactivate pathogens, and can achieve multiple cycles of sterilization. After multiple uses, it can still maintain the ability to sterilize and disinfect, and at the same time, it has high chemical stability and is harmless to the human body.

[0065] The fluid purification module and fluid purification device of the utility model, the guiding function of the support plate, guides the fluid to the light-conducting cotton, and the ultraviolet light source group directed toward the light-conducting cotton directly irradiates the light-conducting cotton to perform catalytic sterilization, thereby improving the efficiency of photocatalysis.

[0066] In the fluid purification module and fluid purification device of the utility model, a support portion is formed on the support plate on the opposite side of the light-conducting cotton accommodating space (first space) for supporting the light source group, and the light output direction of the light source group is toward the light-conducting cotton accommodating space; combined with the excellent ultraviolet light transmittance of the light-conducting cotton, the catalytic efficiency can be improved (no light reflection structure is required), the disinfection structure is simplified, and the cost is reduced.

[0067] The fluid purification module and fluid purification device of the utility model arrange the light-conducting cotton and the light source group reasonably by setting small structures on the support plate, such as the support part, the second window, the limiting net, the air guide plate and the limiting part, so that the light-conducting cotton is set between the light source group and the limiting net, making the disinfection structure more compact, occupying less space, and more conducive to the miniaturization of the device.

[0068] In the fluid purification module and the fluid purification device of the utility model, the light output direction of the ultraviolet light source group is opposite to the fluid outlet of the fluid purification device, so as to prevent the light from being irradiated to the outside of the fluid purification device and causing harm to the human body.
