[0053] In the following text, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0054] As an aspect of the embodiments of the present application, as Figures 1 to 3 shown, this embodiment provides a sterilization device 100, which includes a housing, and the housing includes an end cover 11 and an end shell 12.

[0055] The end cover 11 includes a water outlet 111 and a first cavity 112 that communicate with each other. A first card slot 113 is formed on the inner wall of the first cavity 112.

[0056] The installation position of the water outlet 111 on the end cover 11, the caliber size, caliber shape, etc. of the water outlet 111 can all be selected and adjusted as needed, and no specific limitation is made here. The first cavity 112 can be understood as the space formed by the inner side wall of the end cover 11. The shape and structure of the first inner cavity can be selected and adjusted according to the shape and structure of the end cover 11, and no specific limitation is made here.

[0057] The end shell 12 is connected to the end cover 11. The end shell 12 includes a second cavity 121, and a flow channel 122 is formed in the second cavity 121. The flow channel 122 communicates with the water outlet 111 through the first cavity 112. A second card slot 123 is formed on the inner wall of the second cavity 121.

[0058] The flow channel 122 can be understood as the space formed by the structure of any component within the sterilization device 100. For example, the inner cavity, holes, etc. of any component can serve as the flow channel 122. The flow channel 122 can also be understood as a separate component in the end shell 12 for transporting liquid, or a separate component provided within other components in the end shell 12. The shape and structure of the second inner cavity can be selected and adjusted according to the shape and structure of the end cover 11, and no specific limitation is made here. The connection manner between the end cover 11 and the end shell 12 can be selected as needed. For example, the end cover 11 and the end shell 12 are detachably connected, which is convenient for taking out the devices inside the end shell 12 for replacement and repair, and for cleaning the inside of the end shell 12. The shape and structure, size, and material of the end cover 11 and the end shell 12 can all be selected and adjusted as needed, and no specific limitation is made here. The relative position, caliber size, caliber shape, etc. of the water inlet 127 and the water outlet 111 of the sterilization device 100 can also be selected and adjusted as needed, and no specific limitation is made here.

[0059] The sterilization device 100 further includes a sleeve 2 and a sterilization lamp 3. The sleeve 2 is arranged between the first card slot 113 and the second card slot 123, and the flow channel 122 is located inside the sleeve 2. The sterilization lamp 3 is arranged in the second cavity 121, and the light of the sterilization lamp 3 can irradiate into the flow channel 122. That the light of the sterilization lamp 3 can irradiate into the flow channel 122 can be understood as that the sterilization lamp 3 is arranged outside the flow channel 122, and the light irradiated by the sterilization lamp 3 can penetrate through the second cavity 121 and irradiate into the flow channel 122. It can also be understood as that the sterilization lamp 3 is arranged in the flow channel 122, and the light irradiated by the sterilization lamp 3 directly irradiates into the interior of the flow channel 122.

[0060] The sterilization lamp 3 can adopt any sterilization lamp 3 in the prior art, as long as it can penetrate the second cavity 121 to irradiate and disinfect the liquid in the flow channel 122. For example, the sterilization lamp 3 can adopt an ultraviolet lamp or a mercury lamp.

[0061] Since the sleeve 2 of the embodiment of the present application is arranged between the first card slot 113 and the second card slot 123, the flow channel 122 formed inside the sleeve 2 can be completely isolated from the outside. And, since the light of the sterilization lamp 3 can irradiate into the flow channel 122, the liquid flowing through the flow channel 122 can be irradiated by the light of the sterilization lamp 3 and will not directly contact the sterilization lamp 3, effectively solving the problems of liquid infiltration into the sterilization lamp 3 resulting in electric leakage, equipment damage, and avoiding the problem of secondary pollution caused by the contact between the sterilization lamp 3 and the liquid.

[0062] In one embodiment, as Figures 1 to 3 shown, a first sealing and light-shielding pad 41 is arranged in the first card slot 113. Through the first sealing and light-shielding pad 41, not only can the connection between the sleeve 2 and the first card slot 113 be sealed to prevent the water flowing through the flow channel 122 from leaking, but also the light irradiated by the sterilization lamp 3 can be blocked and absorbed, avoiding the long-term irradiation of the light of the sterilization lamp 3 inside the second cavity 121, which may cause the interior of the second cavity 121 to age or be corroded.

[0063] A second sealing and light-shielding pad 42 is arranged in the second card slot 123. Through the second sealing and light-shielding pad 42, not only can the connection between the sleeve 2 and the second card slot 123 be sealed to prevent the water flowing through the flow channel 122 from leaking, but also the light irradiated by the sterilization lamp 3 can be blocked and absorbed, avoiding the long-term irradiation of the light of the sterilization lamp 3 inside the second cavity 121, which may cause the interior of the second cavity 121 to age or be corroded.

[0064] In one example, the first sealing and light-shielding pad 41 and the second sealing and light-shielding pad 42 can adopt silica gel pads.

[0065] In one embodiment, one end of the end shell 12 is connected to the end cap 11, and the other end of the end shell 12 forms a water inlet 127, and the water inlet 127 communicates with the second cavity 121. The water inlet 127 is used to convey the liquid to be sterilized from the outside into the flow channel 122 of the end shell 12.

[0066] The shape and size of the water inlet 127 can be selected and adjusted as needed, and no specific limitations are provided here. The relative positions of the water inlet 127 and the water outlet 111 can be selected and adjusted as needed, and no specific limitations are provided here. The water flow directions in the water inlet 127, the water outlet 111, and the flow channel 122 can be selected and adjusted as needed, and no specific limitations are provided here. For example, the water inlet 127 can be in the same direction as the water flow in the flow channel 122, and the water flow direction of the water outlet 111 is perpendicular to the water flow direction of the flow channel 122.

[0067] In one embodiment, as Figures 1 to 3 shown, an accommodation groove 124 is formed on the inner wall of one end of the second cavity 121 close to the water inlet 127. The accommodation groove 124 is used to support the sterilization lamp 3, so that the sterilization lamp 3 can be stably arranged in the end shell 12 through the accommodation groove 124, and will not be shaken by the water flow impact and then collide with the inside of the end shell 12 and be damaged. The accommodation groove 124 is located inside the annular second clamping groove 123. The water inlet 127 communicates with the flow channel 122 through a first diversion port on the accommodation groove 124, and the sterilization lamp 3 is connected to the accommodation groove 124.

[0068] In one embodiment, as Figures 1 to 3 shown, a light-shielding cover 43 is arranged between the sterilization lamp 3 and the accommodation groove 124, and the shape of the light-shielding cover 43 is adapted to the accommodation groove 124. An annular boss 431 is arranged at one end of the light-shielding cover 43 facing away from the water inlet 127 (as Figure 3 and Figure 4 shown), and a second diversion port 432 arranged on the annular boss 431 communicates with the first diversion port.

[0069] The light-shielding cover 43 is used to block and absorb the light irradiated by the sterilization lamp 3, and prevent the light of the sterilization lamp 3 from irradiating into the second cavity 121 through the accommodation groove 124 for a long time, so that the inside of the second cavity 121 ages or is corroded. The material of the light-shielding cover 43 can be selected and adjusted as needed. For example, the light-shielding cover 43 can be made of silica gel or other light-absorbing materials.

[0070] The number of the second diversion ports 432 and the first diversion ports can be selected and adjusted as needed. In order to facilitate the liquid at the water inlet 127 to flow smoothly into the flow channel 122, a plurality of first diversion ports and second diversion ports 432 can be provided.

[0071] In one example, the second diversion opening 432 is circumferentially spaced on the annular boss 431. The first diversion opening is circumferentially spaced on the receiving groove 124.

[0072] In one example, in order to enable the water flowing in from the water inlet 127 to smoothly flow into the first diversion opening, a plurality of diversion channels 1231 can be provided on the inner wall of the end of the water inlet 127 close to the receiving groove 124. Thus, the liquid can smoothly flow into the flow channel 122 via the diversion channels 1231 through the first diversion opening, improving the liquid delivery rate and enabling more liquid to be sterilized.

[0073] In one embodiment, as Figure 4 , Figure 5 shown, the second sealing and light-shielding pad 42 provided in the second card slot 123 is integrally provided with the light-shielding cover 43.

[0074] In one embodiment, as Figure 6 shown, a sliding groove 51 is provided on the inner wall of the first cavity 112 close to the end shell 12. The sliding groove 51 includes a first slot portion 511 and a second positioning groove portion 512 that communicate with each other. A convex block 52 is provided on the outer wall of one end of the end shell 12 close to the end cover 11. The convex block 52 is adapted to the first slot portion 511 and the second positioning groove portion 512. When the convex block 52 slides into the second positioning groove portion 512 through the first slot portion 511, the end cover 11 and the end shell 12 are buckled.

[0075] In this embodiment, through the cooperation of the sliding groove 51 and the convex block 52, not only can the detachable connection between the end cover 11 and the end shell 12 be realized, but also the connection between the end cover 11 and the end shell 12 can be made more firm, and it will not gradually come apart due to the impact of the water flow in the flow channel 122.

[0076] In one embodiment, as Figure 7 and Figure 8 shown, a plurality of diversion plates 125 extending towards the middle are circumferentially spaced on the inner wall of one end of the second cavity 121 close to the water inlet 127. Each diversion plate 125 encloses a receiving groove 124. The water inlet 127 is also communicated with the flow channel 122 through the gap 126 between each diversion plate 125.

[0077] Through the gap 126, a part of the liquid in the water inlet 127 can flow into the flow channel 122 through the gap 126, thereby relieving the conveying pressure of the first diversion opening. At the same time, it can also improve the water delivery efficiency and enable the liquid in the water inlet 127 to be stably conveyed to the flow channel 122, avoiding the problem that the water flow in the flow channel 122 is too turbulent and impacts the sterilization lamp 3, causing damage to the sterilization lamp 3.

[0078] The number of the flow guide plates 125 provided and the structure of the flow guide plates 125 can be selected and adjusted as required, and no specific limitation is made herein.

[0079] In one embodiment, as Figures 1 to 3 shown, the germicidal lamp 3 is arranged in the flow channel 122 along the length direction of the end shell 12. One end of the germicidal lamp 3 is connected to the receiving groove 124, and the other end of the germicidal lamp 3 is connected to the slot 114 formed by the inner wall of the first cavity 112.

[0080] In an example, the slot 114 and the receiving groove 124 are arranged opposite to each other.

[0081] In one embodiment, the germicidal lamp 3 includes a light source part 31 and a light-transmitting cover 32. The light-transmitting cover 32 covers the outside of the light source part 31. A closed space is formed on the inner wall of the light-transmitting cover 32 to prevent liquid from entering and contacting the light source part 31 of the germicidal lamp 3. One end of the light-transmitting cover 32 is connected to the receiving groove 124, and the other end of the germicidal lamp 3 is connected to the slot 114 formed by the inner wall of the first cavity 112. Through the receiving groove 124, the germicidal lamp 3 can be stably arranged in the end shell 12, so as to avoid damage caused by the collision between the germicidal lamp 3 and the inner wall of the end shell 12 when the sterilization device 100 vibrates.

[0082] One end shape of the light-transmitting cover 32 is adapted to the receiving groove 124, and the other end shape of the light-transmitting cover 32 is adapted to the slot 114. The light source part 31 is arranged in the light-transmitting cover 32, and the power cord of the light source part 31 extends to the outside of the sterilization device 100 to be connected to an external power supply to supply power to the light source part 31.

[0083] In one embodiment, a third sealing and light-shielding pad 44 is arranged in the slot 114. Through the third sealing and light-shielding pad 44, not only can the connection part between the light-transmitting cover 32 and the slot 114 be sealed to prevent the water flowing through the flow channel 122 from leaking, but also the light irradiated by the germicidal lamp 3 can be blocked and absorbed, so as to avoid the long-term irradiation of the light of the germicidal lamp 3 inside the first cavity 112, causing the aging or corrosion of the inside of the second cavity 121.

[0084] In an example, the third sealing and light-shielding pad 44 can be made of silica gel material.

[0085] In one embodiment, the germicidal lamp 3 includes LED lamp beads and a light-transmitting cover 32. The light-transmitting cover 32 covers the outside of the LED (Light Emitting Diode) lamp beads. The LED lamp beads are accommodated in the receiving groove 124 and are arranged towards the flow channel 122 (not shown in the figure).

[0086] It should be noted that the number of the LED lamp beads and the arrangement manner of the LED lamp beads can be selected and adjusted as required.

[0087] In one example, the material and transparency of the light-transmitting cover 32 can be selected and adjusted according to the type of the sterilizing light of the sterilizing lamp 3, and it is only necessary to ensure that the sterilizing light passes through the light-transmitting cover 32 and irradiates the liquid in the flow channel 122.

[0088] In one embodiment, an opaque reflective layer is provided on the inner wall of the second cavity 121 or the inner wall of the sleeve 2. The opaque reflective layer is used to block the penetration or absorption of the sterilizing light emitted by the sterilizing lamp 3, and can reflect the sterilizing light irradiated on the inner wall of the second cavity 121 or the inner wall of the sleeve 2 back, so that the reflected sterilizing light disinfects and sterilizes the liquid flowing through the flow channel 122 again. Through the repeated reflection of the sterilizing light, an extremely strong light field can be formed in the flow channel 122, effectively improving the sterilization efficiency and quality of the liquid.

[0089] The specific material of the opaque reflective layer can be selected and adjusted according to the type of the sterilizing light of the sterilizing lamp 3. For example, when the sterilizing light is ultraviolet light, the opaque reflective layer can be made of aluminum foil material. The opaque reflective layer can be a coating formed on the inner wall or a thin structure coated on the inner wall.

[0090] In one embodiment, a water flow sensor is further included, which is arranged in the end shell 12. The water flow sensor is electrically connected to the sterilizing lamp 3, and the sterilizing lamp 3 controls the opening and closing of the light source unit 31 according to the water flow detection signal of the water flow sensor.

[0091] In one embodiment, the water flow sensor can be arranged at the water inlet 127. When the water flow sensor detects that there is liquid flowing through the water inlet 127, the sterilizing lamp 3 can be controlled to turn on or the sterilizing lamp 3 can be indirectly controlled to turn on through the control unit that controls the operation of the sterilizing lamp 3.

[0092] It should be noted that the water flow sensor can adopt any sensor used to detect the water flow rate in the prior art, and no specific limitation is made here.

[0093] In this embodiment, since the water flow sensor is arranged at the water inlet 127, it is possible to quickly detect whether there is water flowing through the water inlet 127, so as to effectively control in time that the sterilizing lamp 3 starts to irradiate the liquid with the sterilizing light when there is liquid flowing into the sterilizing device 100 at the beginning. And, since the water flow sensor is directly or indirectly electrically connected to the sterilizing lamp 3, the effective control of the sterilizing lamp 3 can be realized. When water flows into the sterilizing device 100, the sterilizing lamp 3 is turned on, and when there is no water flowing into the sterilizing device 100, the sterilizing lamp 3 is turned off, realizing the instant on and off of the sterilizing lamp 3, so that the sterilizing device 100 can achieve energy conservation.

[0094] In one example, the water flow sensor can be arranged in the water inlet 127. Since the water flow sensor is arranged in the water inlet 127 instead of outside, the unnecessary connection points between the water flow sensor and the water inlet 127 can be reduced, thus solving the problem of water leakage caused by insecure connection when the water flow sensor is connected outside the water inlet 127.

[0095] In one embodiment, the water flow sensor includes a diversion part, a rotating part and a detection part. The diversion part is arranged in the water inlet 127. The diversion part is used to generate a vortex for the water entering the water inlet 127, so that the water can drive the rotating part to rotate. The rotating part is rotatably arranged in the water inlet 127 and away from the water inlet end of the water inlet 127. When the rotating part rotates, a magnetic field will be generated around it. The detection end of the detection part is arranged in the water inlet 127 and close to the impeller, and is used to sense the change of the magnetic field around the rotating part, and directly or indirectly send a detection signal to the germicidal lamp 3 when detecting the magnetic field, so that the germicidal lamp 3 can be turned on, thereby irradiating the water in the flow channel 122 with germicidal light.

[0096] In one embodiment, the diversion part includes a plurality of streamline channels evenly distributed in the circumferential direction. Each streamline channel forms a diversion spiral structure, so that the water passing through the diversion part can form a vortex. The rotating part includes an impeller and a bracket. The bracket is arranged in the water inlet 127, and the impeller is rotatably connected to the bracket. The detection part adopts a Hall switch.

[0097] In one example, according to different installation methods and usage requirements, the water inlet 127 in each embodiment of the present application can also be used as a water outlet, and the water outlet 111 can also be used as a water inlet.
