Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0026] Please refer to Figure 1 and Figure 2 , Figure 1 is a top view of the sterilization device 100 provided by the embodiment of this application; Figure 2 is Figure 1 an exploded view of another perspective of the partial structure of the sterilization device 100 in . The sterilization device 100 includes a housing 10, a light-transmitting member 20, and a sterilization light source 30. The sterilization device 100 can float on the water surface. The housing 10 is provided with a receiving cavity 101. One side of the housing 10 facing the water surface is provided with a light-emitting hole 102 communicating with the receiving cavity 101. The light-transmitting member 20 seals the light-emitting hole 102. The sterilization light source 30 is received in the receiving cavity 101. The sterilization light rays emitted by the sterilization light source 30 are transmitted into the water through the light-transmitting member 20.

[0027] The sterilization device 100 provided by the present application, on the one hand, seals the light-emitting hole 102 based on the light-transmitting member 20, and transmits the sterilization light emitted by the sterilization light source 30 to the water through the light-transmitting member 20, so that the sterilization light source 30 is encapsulated inside the housing 10, thereby reducing the risks of short circuit and electric shock when the sterilization light source 30 is directly immersed in water, and isolating the sterilization light source 30 from the water body through the light-transmitting member 20, and guiding the sterilization light to irradiate into the water can ensure that the sterilization light has a good sterilization effect, and avoid the problem that the water body absorbs and scatters the sterilization light and reduces the penetration ability of the sterilization light when the sterilization light source 30 is directly immersed in water; on the other hand, based on setting the sterilization device 100 to float on the water surface, and a light-emitting hole 102 communicating with the accommodation cavity 101 is provided on one side of the housing 10 facing the water surface, so that the shape of the light and shadow irradiated by the sterilization light source 30 under the water surface is conical, increasing the irradiation area, improving the sterilization effect, and avoiding the problem of harm to the human body caused by the leakage of the sterilization light, and improving the use safety of the sterilization device 100.

[0028] It should be noted that, Figure 2 The purpose is only to schematically describe the setting modes of the housing 10, the light-transmitting member 20 and the sterilization light source 30, and does not specifically limit the connection positions, connection relationships and specific structures of each component, etc. Figure 2 It is only the structure of the sterilization device 100 schematically shown in the embodiments of the present application, and does not constitute a specific limitation on the sterilization device 100. In other embodiments of the present application, the sterilization device 100 may include more or fewer components than Figure 2 shown, or combine some components, or different components. For example, the sterilization device 100 may further include, but is not limited to, an energy storage member, a counterweight member, etc. The energy storage member is used to provide electric energy for the sterilization light source 30. The counterweight member is used to increase the weight of the sterilization device 100, thereby improving the center-of-gravity stability of the sterilization device 100, preventing the sterilization device 100 from tipping over on the water surface, and improving the use safety of the sterilization device 100. For example, the configuration member may be provided at the bottom of the housing 10.

[0029] It should be noted that the sterilization device 100 can achieve the floating function through its own volume and drainage volume. Specifically, when the sterilization device 100 is immersed in the water body, it will be subject to an upward buoyancy force. The buoyancy force of the sterilization device 100 is equal to the weight of the water body displaced by the sterilization device 100, so as to achieve floating by using the balance of buoyancy and gravity, that is, the buoyancy force of the sterilization device 100 is equal to the weight of the sterilization device 100.

[0030] In some embodiments, the housing 10 can be configured as a floating structure as a whole, thereby improving the buoyancy of the housing 10. The material of the housing 10 can include, but is not limited to, at least one of plastics, fiberglass, metals, high molecular materials such as polyethylene, etc. Specifically, the material of the housing 10 includes floating materials. Optionally, in some embodiments, the material of the housing 10 can be selected as a food-grade floating material, that is, the housing 10 will not cause secondary pollution to the water body when immersed in water and has no toxic side effects.

[0031] Of course, in some embodiments, the housing 10 can also be partially configured as a floating structure. For example, the material of some structures of the housing 10 contains floating materials, and the remaining structures do not contain floating materials; or, the housing 10 includes a housing main body and a floating structure provided on the housing main body. Specifically, the housing main body does not contain floating materials, and the floating structure is installed on the housing main body so that the housing 10 can float on the water surface. The housing 10 can be wholly immersed in water or partially immersed in water, and the embodiments of the present application do not make specific limitations.

[0032] The material of the light-transmitting member 20 includes, but is not limited to, glass, acrylic, plastic plates, copolyesters, polycarbonates, etc. Exemplarily, in the present embodiment, the light-transmitting member 20 is configured as a fused quartz glass structure. Thus, due to the high temperature resistance, corrosion resistance, good thermal stability and light-transmitting performance of the fused quartz glass, the transmittance of the sterilizing light rays emitted by the sterilizing light source 30 is improved, and the sterilization effect is enhanced. Of course, in some embodiments, the light-transmitting member 20 can also be configured as other structures with light-transmitting functions, and the embodiments of the present application do not make specific limitations.

[0033] Exemplarily, in the present embodiment, the outer shape of the light-transmitting member 20 is cylindrical, thereby reducing the processing difficulty and assembly difficulty of the light-transmitting member 20. Of course, in some embodiments, the outer shape of the light-transmitting member 20 can also be, but is not limited to, prismatic, frustum-shaped, conical or other regular or irregular shapes. For example, in some embodiments, the light-transmitting member 20 can also disperse the sterilizing light rays emitted by the sterilizing light source 30 to increase the irradiation range of the sterilizing light rays.

[0034] The sterilizing light source 30 is, for example, but not limited to, one or a combination of ultraviolet germicidal lamps, LED germicidal lamps, ozone germicidal lamps, etc. Exemplarily, in the present embodiment, the sterilizing light source 30 is an LED germicidal lamp, thereby avoiding the generation of ozone when the sterilizing light source 30 is working and reducing the harm to the environment and the human body. The product type of the sterilizing light source 30 can be set according to the actual situation, and the embodiments of the present application do not make specific limitations.

[0035] Please refer to Figures 1 to 3 , Figure 3 is Figure 1Cross-sectional view of the sterilization device 100 along the line I-I. In some embodiments, the sterilization device 100 further includes a heat dissipation base 50. The heat dissipation base 50 is hermetically inserted through the light exit hole 102 and is thermally connected to the sterilization light source 30. The heat dissipation base 50 is provided with a light guide channel 501. The opening of the light guide channel 501 faces the sterilization light source 30. The light transmissive member 20 is hermetically disposed in the light guide channel 501. Thus, on the one hand, the heat dissipation base 50 is inserted through the light exit hole 102 to enable the heat dissipation base 50 to contact water, so that most of the heat generated by the sterilization light source 30 can be transferred to the water through the heat dissipation base 50, improving the heat dissipation effect of the sterilization device 100 and extending the service life of the sterilization device 100; on the other hand, based on the light guide channel 501 provided on the heat dissipation base 50 with an opening facing the sterilization light source 30, the light guide channel 501 can homogenize the light emitted by the sterilization light source 30, so that the sterilization light rays emitted by the sterilization device 100 can be evenly distributed and irradiated, improving the sterilization effect, and the setting of the light guide channel 501 can also adjust the irradiation range and intensity of the sterilization light rays emitted by the sterilization light source 30 to avoid harm to pets or aquatic organisms, etc.

[0036] It should be noted that the term "thermally connected" means that heat can be transferred between two components. For example, the heat dissipation base 50 is thermally connected to the sterilization light source 30 means that the heat of the sterilization light source 30 can be conducted to the heat dissipation base 50, and the sterilization light source 30 can be in direct contact with the heat dissipation base 50; or, the sterilization light source 30 can be indirectly in contact with the heat dissipation base 50 through a third component; or, there can be a certain gap between the sterilization light source 30 and the heat dissipation base 50, and this gap can ensure that heat is conducted from the sterilization light source 30 to the heat dissipation base 50.

[0037] The material of the heat dissipation base 50 can be but is not limited to metals, ceramics, etc. Metals can be but are not limited to aluminum, copper, aluminum alloy, etc. Exemplarily, in this embodiment, since aluminum has the advantages of low density, good thermal conductivity, high strength, corrosion resistance, and good processing performance, the material of the heat dissipation base 50 is aluminum. The material of the heat dissipation base 50 can adopt other materials with heat dissipation functions, and the present application does not make specific limitations.

[0038] The heat dissipation base 50 is generally in a hollow tubular structure. The outer side wall of the heat dissipation base 50 is provided with a first stepped structure 51. The housing 10 is provided with a second stepped structure 121 at the edge of the light exit hole 102, and the second stepped structure 121 cooperates with the first stepped structure 51. Thus, the sealing performance of the connection of the heat dissipation base 50 is improved, and the coupling difficulty between the heat dissipation base 50 and the housing 10 is reduced and the reliability of the product is improved.

[0039] In some embodiments, the sterilization device 100 further includes a sealing gasket. The outer sidewall of the heat dissipation base 50 can be hermetically connected to the housing 10 through the sealing gasket, thereby improving the sealing performance of the connection between the heat dissipation base 50 and the housing 10 at the light-emitting hole 102, and avoiding the risks of circuit short-circuit and electric shock when the sterilization light source 30 is immersed in water.

[0040] Exemplarily, the heat dissipation base 50 is provided with a limiting convex ring 52 in the light guide channel 501. The light-transmitting member 20 is hermetically abutted against the limiting convex ring 52, which facilitates the assembly of the light-transmitting member 20 and the heat dissipation base 50, increases the contact area between the heat dissipation base 50 and the water body, improves the heat exchange efficiency between the heat dissipation base 50 and the water body, and improves the heat dissipation effect.

[0041] In some embodiments, the limiting convex ring 52 is provided with a chamfer 521 near the bottom edge of the light guide channel 501, thereby increasing the contact area between the limiting convex ring 52 and the water body, improving the heat exchange efficiency between the heat dissipation base 50 and the water body, improving the heat dissipation effect, and increasing the buoyancy of the housing 10, so that the sterilization device 100 floats on the water surface. Of course, in some other embodiments, the limiting convex ring 52 can be omitted, that is, the light-transmitting member 20 is directly hermetically connected to the inner sidewall of the light guide channel 501.

[0042] In some embodiments, the sterilization device 100 further includes a pressing member 60. The pressing member 60 is disposed in the light guide channel 501 and is used to press the light-transmitting member 20 against the limiting convex ring 52. The pressing member 60 is provided with a through hole 601. The sterilization light source 30 includes a base 31 and a light-emitting member 32 disposed on the base 31, and the light-emitting member 32 is located in the through hole 601. Thus, on the one hand, it facilitates the assembly of the light-transmitting member 20 and the heat dissipation base 50, improves the assembly efficiency of the sterilization device 100 and reduces the processing difficulty of each part of the sterilization device 100; on the other hand, it improves the sealing performance of the connection between the light-transmitting member 20 and the heat dissipation base 50, and avoids the risks of circuit short-circuit and electric shock when the sterilization light source 30 is immersed in water; on the other hand, the light-emitting member 32 is embedded in the through hole 601 provided in the pressing member 60, thereby improving the structural compactness and avoiding the problem that the sterilization light emitted by the sterilization light source 30 leaks laterally and causes harm to the human body, and improving the use safety of the sterilization device 100. Of course, in some other embodiments, the pressing member 60 can be omitted, and the light-transmitting member 20 can also be hermetically connected to the heat dissipation base 50 by screwing.

[0043] The material of the heat dissipation base 50 is suitable for the pressing member 60, which will not be elaborated here. The material of the pressing member 60 can be the same as or different from that of the heat dissipation base 50. Exemplarily, in this embodiment, the material of the pressing member 60 is also aluminum. The pressing member 60 is movably arranged in the light guide channel 501. The outer diameter of the pressing member 60 is smaller than the inner diameter of the light guide channel 501. In other words, the orthographic projection of the pressing member 60 in the axial direction of the light guide channel 501 is located within the light guide channel 501, thereby reducing the manufacturing difficulty of the pressing member 60 and facilitating the assembly of the pressing member 60.

[0044] In some embodiments, the pressing member 60 is configured as a heat conducting structure. One end of the pressing member 60 facing away from the light transmitting member 20 abuts against the base 31, and the pressing member 60 is thermally connected to the inner side wall of the light guide channel 501. Thus, the pressing member 60 can conduct part of the heat generated by the germicidal light source 30 to the heat dissipation base 50, increasing the heat exchange efficiency between the germicidal light source 30 and the heat dissipation base 50 and improving the heat dissipation effect of the sterilization device 100. Exemplarily, in this embodiment, the pressing member 60 is configured as an annular structure, and the outer side wall of the pressing member 60 is attached to the inner side wall of the light guide channel 501. Of course, in some embodiments, the pressing member 60 can also be thermally connected to the inner side wall of the light guide channel 501 through a heat conducting structure. The heat conducting structure is, for example, but not limited to, heat conducting glue, heat conducting gasket, etc.

[0045] In some embodiments, the sterilization device 100 further includes a sealing ring 70. The limiting convex ring 52 and / or the light transmitting member 20 are provided with a limiting groove 502, and the sealing ring 70 is accommodated in the limiting groove 502 and is located between the light transmitting member 20 and the limiting convex ring 52. Thus, on the one hand, the sealing ring 70 can improve the sealing performance of the connection between the light transmitting member 20 and the heat dissipation base 50, avoid the problem of water entering the light guide channel 501 and soaking the germicidal light source 30, and improve the safety of using the sterilization device 100; on the other hand, the sealing ring 70 has elasticity to absorb vibration and avoid the problem of the sterilization device 100 tipping over, and the setting of the sealing ring 70 can reduce the assembly precision requirements for the heat dissipation base 50, the germicidal light source 30, the pressing member 60, etc., facilitating the assembler to carry out the assembly operation, simplifying the assembly procedure, so as to achieve the purpose of reducing costs. The material of the sealing ring 70 can include, but is not limited to, at least one of nitrile rubber, fluororubber, silicone rubber and polyurethane. Exemplarily, in this embodiment, the sealing ring 70 is configured as a rubber ring, saving costs and having good sealing performance.

[0046] In some embodiments, the sterilization device 100 further includes a control circuit board 80. The control circuit board 80 is electrically connected to the sterilization light source 30. The control circuit board 80, the sterilization light source 30, and the heat dissipation base 50 are arranged in sequence. The housing 10 is provided with elastic buckle arms 122 in the accommodation cavity 101. The elastic buckle arms 122 are buckled to the edge of the side of the control circuit board 80 facing away from the sterilization light source 30, so that the sterilization light source 30 is pressed against the pressing member 60. Thus, on the one hand, the arrangement of the elastic buckle arms 122 can reduce the space occupied by the installation structure in the accommodation cavity 101, with a simple structure and facilitating the installation of components such as the control circuit board 80 and the sterilization light source 30; on the other hand, the elastic buckle arms 122 are buckled to the edge of the side of the control circuit board 80 facing away from the sterilization light source 30, so that the sterilization light source 30 is pressed against the pressing member 60, thereby having an anti-loosening and anti-vibration effect between the control circuit board 80 and components such as the sterilization light source 30 and the heat dissipation base 50, ensuring the stability of the connection, ensuring the normal and stable operation of the sterilization device 100, and improving the sealing performance of the heat dissipation base 50 connected to the housing 10 and the light-transmitting member 20 respectively.

[0047] Exemplarily, in this embodiment, the elastic buckle arms 122 include oppositely arranged connection ends 1221 and free ends 1222. The connection ends 1221 are fixedly connected to the housing 10, and the free ends 1222 are configured as elastic hook structures. Two elastic buckle arms 122 are provided. The two elastic buckle arms 122 are opposite and spaced apart. Of course, in some embodiments, the elastic buckle arms 122 can also be provided as one or more than two. The number of the elastic buckle arms 122 can be set according to factors such as the size specifications of the control circuit board 80 and the housing 10, and the embodiments of the present application do not make specific limitations. In some embodiments, multiple elastic buckle arms 122 can also be connected into a whole through a connecting frame, thereby improving the structural strength and force uniformity of the elastic buckle arms 122 and extending the service life. The multiple elastic buckle arms 122 are symmetrically arranged with respect to the center of the control circuit board 80, thereby improving the force uniformity of the control circuit board 80.

[0048] Of course, in some embodiments, the sterilization device 100 can omit the elastic buckle arms 122, and the control circuit board 80 is fixedly installed on the housing 10 through a locking structure to press the sterilization light source 30 against the pressing member 60; or, the sterilization device 100 is provided with both a locking structure and elastic buckle arms 122, and the embodiments of the present application do not make specific limitations.

[0049] In some embodiments, a positioning structure 123 is further provided in the accommodation cavity 101 of the housing 10. The control circuit board 80 and / or the base 31 of the sterilization light source 30 is provided with a guiding structure that cooperates with the positioning structure 123 for fixation, thereby facilitating the alignment and assembly of the housing 10 with the control circuit board 80 and / or the sterilization light source 30, and improving the assembly yield and efficiency. One of the positioning structure 123 and the guiding structure is configured as a rod-shaped structure, and the other is configured as a groove structure or an opening structure that cooperates with the rod-shaped structure. Exemplarily, in this embodiment, two guiding structures are provided, namely a first guiding structure 811 and a second guiding structure 311. The control circuit board 80 is provided with the first guiding structure 811 that cooperates with the positioning structure 123 for fixation, and the base 31 of the sterilization light source 30 is provided with the second guiding structure 311 that cooperates with the positioning structure 123 for fixation. Specifically, the first guiding structure 811 and the second guiding structure 311 are configured as opening structures, and the positioning structure 123 is configured as a rod-shaped structure.

[0050] In some embodiments, the housing 10 is further provided with fixing posts 125 in the accommodation cavity 101. The fixing posts 125 are used to enhance the structural strength of the housing 10. Parts such as the control circuit board 80 and the sterilization light source 30 can be fixed to the housing 10 through a locking structure such as but not limited to screws.

[0051] In some embodiments, the sterilization device 100 further includes a water contact detection terminal 90. The water contact detection terminal 90 is electrically connected to the control circuit board 80. The housing 10 is further provided with a mounting hole 103. The mounting hole 103 communicates with the accommodation cavity 101 and is spaced from the light-emitting hole 102. The water contact detection terminal 90 hermetically passes through and extends out of the mounting hole 103. When the contact area between the water contact detection terminal 90 and the water body meets a preset condition, the closed-loop circuit formed by the water contact detection terminal 90, the control circuit board 80 and the water body is turned on, and the sterilization light source 30 starts the sterilization work; when the contact area between the water contact detection terminal 90 and the water body does not meet the preset condition, the closed-loop circuit formed by the water contact detection terminal 90, the control circuit board 80 and the water body is disconnected, and the sterilization light source 30 stops the sterilization work. It can be understood that the control circuit board 80 is used to receive the induction signal detected by the water contact detection terminal 90 and control the sterilization light source 30 to start working or stop working according to the induction signal. Thus, on the one hand, the water contact detection terminal 90 can automatically start the sterilization work of the sterilization device 100 when detecting water, reducing the labor cost, and automatically control the sterilization device 100 to stop the sterilization work when not detecting water, improving the energy-saving effect and use safety of the sterilization device 100; on the other hand, the water contact detection terminal 90 hermetically passes through and extends out of the mounting hole 103, avoiding the risk of water entering the accommodation cavity 101 from the mounting hole 103 and causing the sterilization light source 30 and the water contact detection terminal 90 to be immersed in water, resulting in circuit short-circuit and electric shock, and improving the accuracy of detection of the water contact detection terminal 90.

[0052] It should be noted that the preset conditions can be set according to the actual situation, and the embodiments of the present application do not make specific limitations. For example, the preset condition can be that the contact area between the water contact detection terminal 90 and the water body is greater than or equal to a preset area value. The preset area value can be the factory setting of the sterilization device 100 or user-defined.

[0053] Specifically, when the water contact detection terminal 90 is in contact with the water body, the closed-loop circuit formed by the water contact detection terminal 90, the control circuit board 80 and the water body is conducted, and the sterilization light source 30 can be started to work and emit sterilization light; when the water contact detection terminal 90 is separated from the water body, the closed-loop circuit formed by the water contact detection terminal 90, the control circuit board 80 and the water body is disconnected, and the sterilization light source 30 can stop working. Exemplarily, in this embodiment, two water contact detection terminals 90 are provided, and the two water contact detection terminals 90 are arranged on opposite sides of the housing 10. One of the water contact detection terminals 90 serves as the positive terminal, and the other water contact detection terminal 90 serves as the negative terminal. Of course, in some embodiments, the water contact detection terminal 90 can also be provided as one, and the water contact detection terminal 90 integrates the positive terminal and the negative terminal.

[0054] Of course, in some embodiments, the sterilization device 100 may further include an emergency button connected to the control circuit board 80. When the water contact detection terminal 90 is abnormal, the user can operate the emergency button to control the sterilization light source 30 to stop working, thereby improving the use safety of the sterilization device 100.

[0055] Exemplarily, in this embodiment, the sterilization device 100 further includes a connection cable 40. A power supply interface 812 is provided on the control circuit board 80. The power supply interface 812 is connected to an external power supply through the connection cable 40, so as to realize the sterilization work of the sterilization light source 30. Specifically, the housing 10 is further provided with a wire passing hole 104 communicating with the accommodation cavity 101, and the wire passing hole 104 is used for the connection cable 40 to pass through. In some embodiments, a sealing plug 13 is further provided at the wire passing hole 104. The sealing plug 13 seals the wire passing hole 104, and the connection cable 40 is hermetically passed through the sealing plug 13, thereby avoiding the risk of water entering the accommodation cavity 101 and causing short circuits and electric shocks to functional components such as the control circuit board 80 and the sterilization light source 30, and improving the use safety of the sterilization device 100. Of course, in some embodiments, a power supply module is integrated on the control circuit board 80, and the power supply module is used to supply power to the sterilization light source 30 to realize the sterilization work of the sterilization light source 30.

[0056] In some embodiments, the connection cable 40 includes a first connector 41, a second connector 42, a first cable 43 and a second cable 44. The two ends of the first cable 43 are respectively connected to the power interface 812 and the first connector 41, and the two ends of the second cable 44 are respectively connected to the first connector 41 and the second connector 42. The first connector 41 is used to connect to an external power source, and the second connector 42 is used to connect to a drinking water device. Thus, the first cable 43 and the second cable 44 are connected as a whole through the first connector 41, which simplifies the connection circuit, reduces the number of cables, saves space, makes the wiring more tidy and beautiful, reduces the complexity and error rate during the wiring process, improves the wiring efficiency, and reduces the overall wiring cost. Of course, in some embodiments, the first cable 43 and the second cable 44 can also be independently arranged.

[0057] Exemplarily, in this embodiment, the first connector 41 and the second connector 42 can both be configured as USB interfaces, so that the connection cable 40 has the advantages of universality, plug-and-play, hot pluggability, high-speed transmission, power supply ability, compact design and low cost. Of course, in some embodiments, the first connector 41 and the second connector 42 can also be, but are not limited to, AC interfaces, DC interfaces, type-C interfaces, etc.

[0058] In some embodiments, the connection cable 40 further includes a control switch 45. The control switch 45 is disposed on the first cable 43, and the control switch 45 is used to conduct or disconnect the electrical connection between the power interface 812 and the external power source. Thus, the user can control the control switch 45 to manually turn off the sterilization light source 30, improving the use safety and convenience of the sterilization device 100. Of course, in some embodiments, the control switch 45 can be omitted, and the embodiments of the present application do not make specific limitations.

[0059] Of course, in some embodiments, the connection cable 40 further includes a sheath 46. The sheath 46 is sleeved on at least a partial section of the outer side of the first cable 43. Thus, on the one hand, the sheath 46 can protect the first cable 43, reducing the risk of the first cable 43 being pinched or scratched by the housing of the drinking water device; on the other hand, the sheath 46 can shape the first cable 43, thereby improving the aesthetics of the connection cable 40, as well as improving the reliability and stability of the connection circuit of the connection cable 40. The sheath 46 can be configured as, but is not limited to, an elastic structure, a metal cover, etc. The material of the elastic structure can include, but is not limited to, at least one of rubber, sponge, fiber, etc. The sheath 46 is configured as a transparent structure, so as to facilitate the user to observe the connection condition of the first cable 43 and improve the visual experience. Of course, the sheath 46 can also be configured as a non-transparent structure.

[0060] In some embodiments, a control switch 45 and a sheath 46 are simultaneously provided on the first cable 43 of the connection cable 40. The sheath 46 can be provided independently of the control switch 45; or, the sheath 46 is sleeved outside the control switch 45.

[0061] Please refer to Figure 2 and Figure 4 , Figure 4 is Figure 1 a side view of the sterilization device 100 in

[0062] Exemplarily, in this embodiment, the heat dissipation base 50 protrudes relatively from the housing 10. In the height direction Z of the sterilization device 100, the free end face of the heat dissipation base 50 facing away from the sterilization light source 30 is higher than the free end face of the water contact detection terminal 90 facing away from the control circuit board 80. Thus, on the one hand, due to the heat dissipation base 50 protruding relatively from the housing 10, the contact area between the heat dissipation base 50 and the water body is increased, improving the heat dissipation effect of the heat dissipation base 50 on the sterilization light source 30 and the control circuit board 80; on the other hand, the free end face of the heat dissipation base 50 facing away from the sterilization light source 30 is higher than the free end face of the water contact detection terminal 90 facing away from the control circuit board 80. Thus, when the water volume is very small, since the free end face of the water contact detection terminal 90 is higher than the free end face of the heat dissipation base 50, the water storage detection terminal separates from the water body earlier than the heat dissipation base 50, controlling the sterilization light source 30 to stop sterilization work, thereby avoiding the functional components of the sterilization device 100 from being burned out, and further improving the use safety and energy-saving effect of the sterilization device 100.

[0063] The length of the sterilization device 100 in the length direction X of the sterilization device 100 is 40 mm - 50 mm, the length of the sterilization device 100 in the width direction Y of the sterilization device 100 is 40 mm - 50 mm, and the height of the sterilization device 100 in the height direction Z of the sterilization device 100 is 15 mm - 30 mm. Thus, the overall structure of the sterilization device 100 has a small volume and is suitable for use scenarios of water storage structures with different volumes. Exemplarily, in this embodiment, the length of the sterilization device 100 in the length direction X of the sterilization device 100 is 48.5 mm, the length of the sterilization device 100 in the width direction Y of the sterilization device 100 is 47.8 mm, and the height of the sterilization device 100 in the height direction Z of the sterilization device 100 is 21.0 mm.

[0064] For the sake of accurate description, whenever directions are involved in this article, please always take Figure 2 as a reference. The height direction Z refers to the arrangement direction of the sterilization light source 30 and the control circuit board 80, that is, the direction parallel to the sterilization route emitted by the sterilization light source 30. The width direction Y refers to the arrangement direction of the two water contact detection terminals 90, and the length direction X is the direction perpendicular to the height direction Z and the width direction Y. For the sake of convenient description, the length direction X, width direction Y, and height direction Z of the sterilization device 100 can be customized according to the specific structure of the product and the perspective presented in the drawings, and the present application does not make specific limitations.

[0065] In some embodiments, the length of the sterilization device 100 in the length direction X of the sterilization device 100 gradually decreases from the middle to both sides, the width of the sterilization device 100 in the width direction Y of the sterilization device 100 gradually decreases from the middle to both sides, and the height of the sterilization device 100 in the height direction Z of the sterilization device 100 gradually decreases from the middle to both sides. Thus, the center of gravity stability of the sterilization device 100 is improved, preventing the sterilization device 100 from tipping over on the water surface and improving the safety of using the sterilization device 100.

[0066] In some embodiments, the first arc portion 110 and the second arc portion 120 are respectively provided at both ends of the housing 10 in the length direction X of the sterilization device 100. The taper of the second arc portion 120 is greater than the taper of the first arc portion 110. The heat dissipation seat 50 is disposed on the side of the housing 10 close to the first arc portion 110, and the sealing plug 13 is also installed on the side of the housing 10 close to the first arc portion 110, thereby avoiding the problem that the sterilization device 100 tips over on the water surface when the connecting cable 40 is pulled, improving the safety of using the sterilization device 100, and providing sufficient space to install the heat dissipation seat 50, with a reasonable and compact structural layout.

[0067] Please refer to Figure 2 、 Figure 3 and Figure 5 , Figure 5 isExploded view of the first housing 11 and the second housing 12 of the sterilization device 100 in Figure 1 . In some embodiments, the housing 10 includes a first housing 11 and a second housing 12. The first housing 11 is located above the second housing 12 and is connected to the second housing 12 to form a receiving cavity 101. The elastic buckle arm 122 is disposed on the inner sidewall of the second housing 12. Thus, based on disposing the elastic buckle arm 122 on the inner sidewall of the second housing 12, so that the control circuit board 80, the sterilization light source 30 and the heat dissipation base 50 can be distributed as much as possible at the bottom of the receiving cavity 101. On the one hand, the center of gravity of the sterilization device 100 is reduced, the center of gravity stability of the sterilization device 100 is improved, the sterilization device 100 is prevented from tipping over on the water surface, and the safety of using the sterilization device 100 is improved; on the other hand, most of the internal space of the first housing 11 is hollow, so that by increasing the volume of the housing 10, the volume of water displaced by the housing 10 can be increased, and further the buoyancy of the sterilization device 100 is increased, making the sterilization device 100 easier to float on the water surface and improving the sterilization effect of the sterilization device 100.

[0068] The outer shape of the second housing 12 can be but is not limited to a boat shape, a bowl shape or a disk shape, so as to increase the contact area between the housing 10 and the water body, and further increase the buoyancy of the sterilization device 100, making the sterilization device 100 easier to float on the water surface and improving the sterilization effect of the sterilization device 100.

[0069] Please refer to Figure 2 and Figure 6 , Figure 6 is a schematic structural diagram of a sterilization system 1000 provided by an embodiment of the present application. An embodiment of the present application also provides a sterilization system 1000, including a drinking water device 200 and the above-mentioned sterilization device 100. The sterilization device 100 is placed in the drinking water device 200 and is used for sterilizing the liquid stored in the drinking water device 200.

[0070] Exemplarily, in this embodiment, the drinking water device 200 is used to store the liquid for pets to drink. The pets can be but are not limited to cats, dogs, ducks, alpacas, etc. In some embodiments, the sterilization system 1000 further includes a drinking tray 300. The drinking tray 300 is communicated with the drinking water device 200 and is used for carrying the water sterilized by the drinking water device 200.

[0071] ​In some embodiments, the sterilization system 1000 further includes a water pump 400 disposed in the drinking water device 200. The water pump 400 is configured to deliver the water in the drinking water device 200 into the drinking tray 300. Exemplarily, the drinking tray 300 is disposed above the drinking water device 200, so as to avoid the problem that the sterilizing light emitted by the sterilization device 100 harms pets. Of course, in some embodiments, the drinking tray 300 is disposed at the side of the drinking water device 200, and the embodiments of the present application do not make specific limitations. The sterilization system 1000 may not include the water pump 400, and the drinking tray 300 is in internal communication with the drinking water device 200 through a regulating valve.

[0072] When the sterilization device 100 is placed in the drinking water device 200, the sterilization device 100 floats on the water surface, and at least a part of the sterilization device 100 extends below the water level line P. When the water level line P of the drinking water device 200 is within the first position range, the water contact detection terminal 90 contacts the water body. At this time, the closed-loop circuit formed by the water contact detection terminal 90, the control circuit board 80, and the water body is turned on, and the sterilization light source 30 can be started to work and emit sterilizing light. The shape of the light and shadow irradiated by the sterilization light source 30 under the water surface is a conical irradiation area A, thereby increasing the irradiation area, improving the sterilization effect, and avoiding the problem that the sterilizing light leaks and harms the human body, and improving the use safety of the sterilization device 100. When the water level line P of the drinking water device 200 is within the second position range, the water contact detection terminal 90 is separated from the water body. At this time, the closed-loop circuit formed by the water contact detection terminal 90, the control circuit board 80, and the water body is disconnected, and the sterilization light source 30 can be stopped from working, so as to avoid burning out the functional components of the sterilization device 100, and further improve the use safety and energy-saving effect of the sterilization device 100. It should be noted that the first position range may refer to the area where the water in the drinking water device 200 contacts the water contact detection terminal 90 to turn on the closed-loop circuit formed by the water contact detection terminal 90, the control circuit board 80, and the water body. The second position range may be the area where the water in the drinking water device 200 is separated from or partially contacts the water contact detection terminal 90 to disconnect the closed-loop circuit formed by the water contact detection terminal 90, the control circuit board 80, and the water body. The first position range and the second position range can be set according to the actual situation, and the embodiments of the present application do not make specific limitations.

[0073] It should be noted that when the water body in the drinking water device 200 is sterilized, the sterilization device 100 can be placed inside the drinking water device 200 all the time until the water body in the drinking water device 200 is used up, thereby improving the sterilization effect of the sterilization device 100. Of course, when the water body in the drinking water device 200 is sterilized, the sterilization device 100 can also be placed inside the drinking water device 200 periodically, thereby saving energy consumption and extending the service life of the sterilization device 100. The use of the sterilization device 100 can set the sterilization time according to the actual situation, and the embodiments of the present application do not make specific limitations.

[0074] As mentioned above, the above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
