[0023] The following is for reference. Figure 1 and Figure 2 This invention describes an ultraviolet disinfection device according to an embodiment of the present invention.

[0024] like Figure 1 and Figure 2 As shown, the ultraviolet disinfection device according to an embodiment of the present invention includes an inner liner 100 and an ultraviolet lamp 200.

[0025] Reference Figure 3 , Figure 4 The inner liner 100 is made of UV-resistant material. The inner liner 100 has an inner liner wall panel 110 and an inner liner cavity 120. A lamp mounting position 130 is provided on the inner liner wall panel 110, and a lamp hole 131 is formed in the lamp mounting position 130. A UV lamp 200 is mounted on the upper lamp mounting position 130 on the outer side of the inner liner wall panel 110 via a fixing member. The direction of the UV lamp 200 and the inner liner wall panel 110 closest to the inner liner cavity 120 is defined as the proximal end, and the direction of the UV lamp 200 and the inner liner wall panel 110 furthest from the inner liner cavity 120 is defined as the distal end. (Refer to...) Figure 5 The ultraviolet lamp 200 includes a lamp holder 210 at the near end and a lamp panel 220 at the far end. The lamp holder 210 is provided with a lamp holder lamp hole 211, and the lamp panel 220 is provided with an LED 221 at the near end. The lamp holder lamp hole 211 and the wall panel lamp hole 131 are located at the same position, and the LED 221 is located in the lamp holder lamp hole 211 and the wall panel lamp hole 131.

[0026] For example, such as Figure 1 and Figure 2 As shown, the inner liner 100 is made of UV-resistant material to ensure that the inner liner 100 itself will not age due to UV exposure. (Refer to...) Figure 3 , Figure 4 The inner liner 100 has an inner liner wall panel 110 and an inner liner cavity 120, forming a sterilization cavity. A lamp mounting position 130 is provided on the inner liner wall panel 110, and a wall panel lamp hole 131 is opened in the lamp mounting position 130 to ensure that the ultraviolet light emitted by the ultraviolet lamp 200 can pass through the wall panel lamp hole 131 and irradiate the inner liner cavity 120. The ultraviolet lamp 200 is located on the upper lamp mounting position 130 on the outer side of the inner liner wall panel 110, that is, the ultraviolet lamp 200 is located on the outer side of the inner liner 100, thus reducing the aging effect of ultraviolet light on the ultraviolet lamp 200. The direction of the ultraviolet lamp 200 and the inner liner wall panel 110 closer to the inner liner cavity 120 is defined as the proximal end, and the direction of the ultraviolet lamp 200 and the inner liner wall panel 110 farther from the inner liner cavity 120 is defined as the distal end. (Refer to...) Figure 5The ultraviolet lamp 200 includes a near-end lamp holder 210 and a far-end lamp panel 220, which are fixed relative to each other. The lamp holder 210 has a lamp holder aperture 211, and the lamp panel 220 has an LED 221 near its end. The lamp holder aperture 211 coincides with the wall panel aperture 131, and the LED 221 is located within both the lamp holder aperture 211 and the wall panel aperture 131. The ultraviolet light emitted by the LED 221 can pass through the lamp holder aperture 211 and the wall panel aperture 131 and irradiate into the inner cavity 120.

[0027] In actual operation, utensils requiring sterilization, such as baby bottles, can be placed inside the inner cavity 120 of the inner liner 100. The ultraviolet lamp 200 outside the inner liner 100 emits ultraviolet light through lamp beads 221. This ultraviolet light passes through the lamp holder hole 211 on the ultraviolet lamp 200 and the wall panel hole 131 on the inner liner wall panel 110, illuminating the inner cavity 120. Ultraviolet sterilization is a non-chemical sterilization method. During ultraviolet sterilization, microorganisms on the baby bottle are exposed to ultraviolet light. The ultraviolet energy is absorbed by DNA or RNA, causing these molecular chains to break or form photochemical products, thereby preventing the replication and reproduction of microorganisms, resulting in the death of vegetative cells and / or regenerative cells, achieving the sterilization effect on the baby bottle.

[0028] Since the UV lamp 200 is installed outside the inner liner 100, with only the LED beads 221 remaining inside the lamp holder's lamp hole 211 and the wall panel's lamp hole 131, and considering the characteristic that UV disinfection cannot penetrate solid materials, it can be ensured that the UV light emitted by the LED beads 221 remains within the inner liner cavity 120, without affecting the UV lamp 200 and other components outside the inner liner 100. This reduces or even prevents the UV lamp 200 from aging due to UV exposure.

[0029] In some embodiments of this utility model, the inner wall panel 110 defines the inner cavity 120. The inner wall panel 110 includes an upper wall panel 111, a lower wall panel 112, a left wall panel 113, a right wall panel 114, and a rear wall panel 115. Ultraviolet lamps 200 are installed on the upper wall panel 111, lower wall panel 112, left wall panel 113, and right wall panel 114. This ensures that the inner cavity 120 is exposed to ultraviolet light from all four sides, guaranteeing a more thorough disinfection effect. The inner liner 100 has an opening on its front side, and a cabinet door 321 is provided on the front side of the inner liner 100. The cabinet door 321 can be opened and closed, facilitating the placement of utensils to be disinfected within the inner liner 100.

[0030] The front of the inner liner 100 serves as an opening for installing cabinet doors or other similar window structures, facilitating user observation and use. The rear wall panel 115 does not require the installation of the UV lamp 200, reducing the direct impact of its light on the user.

[0031] As can be imagined, the installation directions of each UV lamp 200 are different, and the actual directions of the near and far ends of the inner wall panel 110 and the corresponding UV lamp 200 are also different. For example, the near end of the UV lamp 200 on the upper wall panel 111 is on the lower side and the far end is on the upper side; the near end of the UV lamp 200 on the lower wall panel 112 is on the upper side and the far end is on the lower side; the near end of the UV lamp 200 on the left wall panel 113 is on the right side and the far end is on the left side; the near end of the UV lamp 200 on the right wall panel 114 is on the left side and the far end is on the right side.

[0032] In some embodiments of this utility model, reference is made to Figure 7 , Figure 8 The lamp holder 210 has lamp connecting plates 212 on both the front and rear sides. The lamp connecting plates 212 are connected to the inner wall panel 110 by fasteners, which facilitates the installation and removal of the ultraviolet lamp 200 in the inner wall 100.

[0033] In some specific embodiments of this utility model, the fixing component can be a connecting component such as screws, bolts, or clips. Additionally, the ultraviolet lamp component 200 can also be installed on the inner liner 100 by means of adhesive or other methods.

[0034] In some specific embodiments of this utility model, the fastener is made of metal material, which can avoid the fastener being affected by ultraviolet aging.

[0035] It is conceivable that the lamp connecting plate 212 can also be set on the left and right sides of the lamp holder 210 or in other positions, which will not be elaborated here.

[0036] In some embodiments of this utility model, reference is made to Figure 6 , Figure 9 , Figure 10 The lamp mounting position 130 has non-circular holes 140 on both the front and rear sides of the wall panel; the fasteners include screws 150 and nuts 160, the screws 150 have a non-circular screw head 151 at the proximal end and a threaded portion 152 at the distal end; the lamp connecting plate 212 has a screw hole 2121, the non-circular screw head 151 is located in the non-circular hole 140 of the wall panel, the side wall of the non-circular screw head 151 is stuck in the hole wall of the non-circular hole 140 of the wall panel, the threaded portion 152 extends to the distal end through the screw hole 2121, and the threaded portion 152 is fitted with a nut 160, the non-circular screw head 151 and the nut 160 clamp the inner wall panel 110 and the lamp connecting plate 212.

[0037] The fasteners utilize screws 150 and nuts 160 with non-circular heads 151. Non-circular holes 140 on the front and rear sides of the lamp mounting position 130 are used to accommodate the non-circular head portion of the fasteners. A screw hole 2121, specifically designed to match the screw 150, is provided on the lamp connecting plate 212. During installation, the non-circular head 151 can be precisely inserted into the non-circular hole 140 in the wall panel. The non-circular sidewall shape of the non-circular head 151 fits tightly against the hole wall of the non-circular hole 140, ensuring no rotation occurs. The threaded portion 152 extends distally through the non-circular hole 140 in the wall panel and the screw hole 2121 in the lamp connecting plate 212, and is secured at the end with a nut 160. This structural design allows the non-circular head 151 and nut 160 to firmly clamp the inner wall panel 110 and the lamp connecting plate 212, forming a stable and reliable connection. The entire installation process ensured both the ease of assembling the UV lamp component 200 and the robustness and stability of its connection.

[0038] In some embodiments of this utility model, reference is made to Figure 3 , Figure 10 The non-circular hole 140 of the wall panel is a concave countersunk hole structure formed by bending the inner wall panel 110. The non-circular hole 140 of the wall panel has a non-circular countersunk recess 141, and the outer wall of the non-circular screw head 151 abuts against the inner wall of the non-circular countersunk recess 141. The lamp connecting plate 212 has a non-circular countersunk hole 2122 at its near end. The screw hole 2121 is located in the non-circular countersunk hole 2122 of the connecting plate, and the outer wall of the non-circular countersunk recess 141 abuts against the inner wall of the non-circular countersunk hole 2122 of the connecting plate.

[0039] The non-circular hole 140 in the wall panel is a concave countersunk hole structure formed by bending the inner wall panel 110. Specifically, the non-circular hole 140 is bent to form at least a non-circular countersunk recess 141. The shape of this recess is specially designed so that it can form a tight fit with the non-circular screw head 151 on the screw 150, and also with the non-circular countersunk hole 2122 on the lamp connecting plate 212.

[0040] During actual assembly, the outer wall of the non-circular screw head 151 can precisely abut against the inner wall of the non-circular countersunk recess 141, forming a stable mechanical embedded connection. Simultaneously, the non-circular countersunk hole 2122 machined near the end of the lamp connecting plate 212 also mates with the non-circular hole 140 in the wall plate. The screw hole 2121 is precisely positioned within the internal space of the non-circular countersunk hole 2122, allowing the threaded portion 152 to pass through the non-circular countersunk recess 141, connect threadedly with the screw hole 2121, and extend distally. The outer wall of the non-circular countersunk recess 141 tightly abuts against the inner wall of the non-circular countersunk hole 2122, thus ensuring the stability and reliability of the entire connection system. This design not only achieves precise positioning of the screw 150 for the UV lamp 200 but also provides better stress support for the UV lamp 200, making the overall structure more robust and durable.

[0041] In some embodiments of this utility model, an alignment groove 132 is provided on the outer side of the inner wall panel 110, and the alignment groove 132 is located on the lamp mounting position 130; an alignment protrusion 213 is provided near the lamp holder 210, and the lamp connecting plate 212 is located on the front and rear sides of the alignment protrusion 213, and the alignment protrusion 213 is inserted into the alignment groove 132.

[0042] The UV lamp 200 and the inner liner 100 can be aligned using the aforementioned alignment groove structure. The outer surface of the inner liner wall panel 110 is precisely machined with an alignment groove 132, which can be formed by bending or cold pressing. The alignment groove 132 corresponds to the lamp mounting position 130. Correspondingly, the near end of the lamp holder 210 also has a matching alignment protrusion 213. The lamp connecting plate 212 is arranged on both sides of the alignment protrusion 213, forming a symmetrical layout and ensuring the UV lamp 200 is securely installed.

[0043] During assembly, the operator only needs to accurately align the alignment protrusion 213 on the lamp holder 210 into the alignment groove 132 on the outer side of the inner liner wall panel 110, and then fix the mounting fasteners on the inner liner wall panel 110 and the lamp connecting plate 212. This plug-in mating method ensures both the accuracy of the UV lamp 200 installation and the stability of the UV lamp 200 on the inner liner 100. The entire assembly process described above meets the requirements for installation accuracy and structural reliability.

[0044] In some embodiments of this utility model, reference is made to Figure 9 , Figure 10 A lamp guard plate 230 is provided between the lamp holder 210 and the lamp plate 220. A lamp cover 231 is provided near the lamp guard plate 230. The lamp cover 231 has a lamp cover hole 232. The lamp bead 221 is located inside the lamp cover hole 232. The outer wall of the lamp cover 231 abuts against the hole wall of the lamp holder lamp hole 211.

[0045] In the aforementioned UV lamp 200 structure, a protective plate 230 positioned between the lamp holder 210 and the lamp panel 220 protects the lamp panel 220, particularly the LEDs 221 on it. The end of the protective plate 230 near the LEDs 221 is specially designed with a protective cover 231. This protective cover 231 has a cover hole 232, allowing the LEDs 221 to be precisely embedded and fixed inside the cover hole 232, thus providing protective protection for the optical elements of the lamp panel 220. Simultaneously, the outer wall of the protective cover 231 is in close contact with the inner wall of the lamp hole 211 on the lamp holder 210. This structural design achieves stable support and precise positioning of the LEDs 221 by the protective cover 231, ensuring the structural stability between the protective plate 230 and the lamp holder 210, and consequently guaranteeing sufficiently stable optical performance of the UV lamp 200.

[0046] In some embodiments of this utility model, reference is made to Figure 5 , Figure 10 A ring 133 is provided on the outer side of the inner wall panel 110. The ring 133 is connected to the wall of the lamp hole 131 on the wall panel, and the outer wall of the ring 133 abuts against the inner wall of the lamp cover 231.

[0047] The outer side of the inner wall panel 110, specifically the distal end of the inner wall panel 110, is also made of UV-resistant material, integral with the inner liner 100. The outer wall of the ring 133 fits tightly against the inner wall of the lamp cover 231, thus forming a stable support structure for the UV lamp 200. This design not only ensures the stability of the UV lamp 200 installation and effectively prevents displacement or loosening of the lamp cover 231 of the lamp panel 230 and the lamp beads 221 of the lamp plate 220 during use, but the ring 133 also serves to block UV rays. That is, the UV light emitted by the lamp beads 221 is blocked by the ring 133 and does not shine on the lamp cover 231 of the lamp panel 230 or the lamp holder lamp hole 211 of the lamp holder 210; the UV light passes directly through the ring 133 and enters the inner liner cavity 120. This prevents the lamp holder 210 and lamp guard plate 230 of the UV lamp from aging due to ultraviolet radiation, and further extends the service life of the UV lamp 200.

[0048] In some embodiments of this utility model, reference is made to Figure 8 , Figure 10 The lamp holder 210 has a mounting cavity 214 at its far end. The mounting cavity 214 has a buckle 215 inside. The lamp plate 220 is located inside the mounting cavity 214. The buckle 215 holds the edge of the lamp plate 220, making it easy to install and remove the lamp plate 220.

[0049] It is conceivable that, as mentioned above, the inner liner 100 is made of a UV-resistant material. Under this premise, the UV-resistant material specifically used for the inner liner 100 can be a metal material, or it can be polycarbonate (PC), polyimide (PI), polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), polypropylene (PP), or polyethylene (PE). Furthermore, by coating the surface of the inner liner 100 with a UV-resistant material and a coating or paint that has UV resistance, the inner liner 100 can be effectively protected from the aging effects caused by UV radiation. The above methods and other similar existing technologies are all within the scope of protection of this patent. According to a second aspect of the present invention, the integrated sterilization and milk preparation machine includes the ultraviolet sterilization device according to the first aspect of the present invention, and further includes a base 300, a milk preparer 310 and a sterilizer 320, wherein the milk preparer 310 and the sterilizer 320 are located on the upper side of the base 300, and the inner liner 100 is located inside the sterilizer 320.

[0050] In actual use, when formula needs to be prepared, the bottle is placed on the formula maker 310. The formula maker 310 uses a built-in temperature sensor to precisely control the water temperature, ensuring the optimal temperature for preparing the formula and avoiding overheating or cooling that could harm the baby's digestive system. When the bottle needs to be sterilized, it is placed in the inner container 100.
