The embodiment of the present disclosure provides a sterilization module, which can be selectively mounted on a water flow path component such as a faucet, a water purifier, a water supply pipe, etc., and can be used for sterilizing water flowing through to achieve a water purification effect.

As shown in fig. 1 to 3, the sterilization module in the embodiment of the present disclosure mainly includes two main components, namely, a module outer housing 100 and an ultraviolet sterilization module 200. Wherein the module case body 100 serves as a protective case body and is constructed with a path through which water passes in the interior thereof; the ultraviolet sterilization module 200 is a functional device based on an ultraviolet sterilization principle, and is used to irradiate ultraviolet light to water flowing through a module housing, so that microbes mixed in the water can be killed by the ultraviolet light.

In an embodiment, as shown in fig. 3, the module case body 100 is internally configured with a flow passage as a path through which water flows; and the two end parts of the module outer housing 100 are respectively provided with a first water inlet 121 and a first water outlet 131, and the flow passage is communicated with the first water inlet 121 and the first water outlet 131, so that water flows into the module outer housing 100 from the first water inlet 121 and flows out from the first water outlet 131 through the flow passage, and the black arrows in fig. 3 indicate the flow direction of the water.

Illustratively, the module case 100 is configured as a case structure having a circular cross section and a cylindrical outer contour, and has a hollow space inside as a flow passage; the first water inlet 121 and the first water outlet 131 are respectively provided at the center positions of both axial end portions of the module case body 100.

In this example, the module case 100 includes a split structure of a cylinder section 110, and a water inlet end cover 120 and a water outlet end cover 130 disposed at two axial ends of the cylinder section 110. The barrel section 110 is in the form of a structure with two open ends in the axial direction, as shown in fig. 4; the water inlet end cover 120 is covered on one opening of the cylinder section 110, and the first water inlet 121 is disposed on the water inlet end cover 120, as shown in fig. 5; the water outlet end cap 130 covers the opening at the other end of the cylinder section 110, and the water outlet end cap 130 is provided with a first water outlet 131, as shown in fig. 6. The inlet end cap 120 and the outlet end cap 130 are detachably connected to the cylinder section 110, so that other components of the sterilization module (e.g., the ultraviolet sterilization module 200) can be conveniently installed inside the module housing 100.

Optionally, as shown in fig. 3, an external thread sleeve formed by extending and forming along the axial direction outwards is formed on an end surface of the water inlet end cover 120 facing the cylinder segment 110, an internal thread is formed on an inner wall of a corresponding end of the cylinder segment 110, and an outer diameter of the external thread sleeve is adapted to an inner diameter of the cylinder segment 110, so that the water inlet end cover 120 and the end of the cylinder segment 110 are fixed by thread sleeve fit; optionally, an end surface of the water outlet end cover 130 facing the cylinder end is formed with an internal threaded sleeve extending axially outward, an outer wall of the corresponding end of the cylinder section 110 is formed with an external thread, and an inner diameter of the internal threaded sleeve is adapted to an outer diameter of the cylinder section 110, so that the water outlet end cover 130 and the end of the cylinder section 110 are fixed by the threaded sleeve.

Optionally, the module case housing 100 further includes a speed reducer 140, the speed reducer 140 being disposed on the water flow path of the inlet end cap 120 and/or the outlet end cap 130.

Taking the decelerating element 140 disposed on the water inlet end cap 120 as an example, as shown in fig. 5, the decelerating element 140 is a petal-shaped structure which is disposed on the inner side surface of the water inlet end cap 120, extends outward along the circumferential direction of the first water inlet 121, and is formed with a plurality of water blocking blocks 141 at intervals, the intervals between adjacent water blocking blocks 141 are used as paths for water flow flowing from the first water inlet 121 to the flow passage, so that the flow path area of the inflowing water flow is separated and reduced by the plurality of water blocking blocks 141, so that the water flow generates a certain deceleration.

The speed reducer 140 is arranged on the water flow path of the water inlet end cover 120 and/or the water outlet end cover 130, so that on one hand, the flow speed of water flow can be delayed, the irradiation time of the water flow passing through the ultraviolet sterilization module 200 can be prolonged, and the sterilization effect of the sterilization module can be further improved; on the other hand, the water flow filter can also play a role in filtering the water flow, and further can improve the safety of water use.

In yet another alternative example not shown in the drawings, the module case 100 is configured in a case structure with a rectangular cross section and a square cylindrical outer contour, and a hollow space is formed inside as a flow passage; a first water inlet 121 and a first water outlet 131 are respectively provided at the central positions of both longitudinal ends thereof.

In this example, the module case 100 includes an upper case and a lower case divided along a longitudinal center line, the upper case is a semi-closed rectangular case structure with an open bottom surface, the lower case is a semi-closed rectangular case structure with an open top surface, and the upper case and the lower case can be correspondingly and openly combined to form a closed square cylindrical case. The upper cover and the lower cover of the barrel in the example are also detachably connected, and the effect of conveniently installing other components of the sterilization module can be realized.

In the above example, the flow passage is formed by extending along the axial direction or the longitudinal direction of the module outer housing 100, so that the internal space of the module outer housing 100 can be effectively utilized and the actual length of the flow passage can be increased, so that the ultraviolet sterilization module 200 can cover more water flow areas during sterilization, and the sterilization effect can be improved. It should be understood that the above technical contents are only preferred examples of the structural form of the module case body 100, and do not limit the structural form of the module case body 100, and those skilled in the art can adjust the structural form of the module case body 100 according to actual needs, and shall also be covered by the protection scope of the present application.

In some alternative embodiments, the first water inlet 121 is a circular water hole, and the first water outlet 131 is a circular water hole.

In some embodiments, to facilitate the connection of the sterilization module with other water path components, a water inlet joint 122 is further provided at the first water inlet 121, and a water outlet joint 132 is provided at the first water outlet 131, as shown in fig. 2, so that the water inlet joint 122 and the water outlet joint 132 are used to mate with other water path components.

Optionally, the water inlet joint 122 and the first water inlet 121 are formed integrally, and/or the water outlet joint 132 and the first water outlet 131 are formed integrally; the integrally formed structure is beneficial to improving the tightness of the module outer shell 100 at the water inlet and the water outlet, so as to reduce the occurrence of water leakage.

In this embodiment, in order to improve the sealing performance, an elastic sealing gasket is disposed at a joint position between the water inlet joint 122 and the first water inlet 121, so as to seal a gap therebetween by the sealing gasket; similarly, an elastic sealing gasket is also arranged at the joint of the water outlet joint 132 and the first water outlet 131, and is also used for closing the fit clearance between the water outlet joint 132 and the first water outlet 131.

Here, the gasket may be made of rubber, graphite, or the like.

In some alternative embodiments, as shown in fig. 2 and 3, the uv sterilization module 200 includes a uv lamp 210, a circuit board 220, and a power supply line 230, wherein the uv lamp 210 serves as an irradiation end of the uv emitting pipeline, and the irradiation area covers at least a portion of the flow passage pipeline to sterilize the water flowing through the flow passage pipeline; the circuit board 220 is used for controlling the start and stop of the irradiation of the ultraviolet lamp 210 beads, the illumination intensity and the like; the power supply line 230 is connected to the circuit board 220 and leads out of the module case 100 so that external power can be introduced and supplied to the circuit board 220 and the ultraviolet lamp 210.

In fig. 2, the ultraviolet lamp 210 and the circuit board 220 are sequentially stacked along the axial direction, and the circuit board 220 is located on the backlight side of the ultraviolet lamp 210.

Optionally, the ultraviolet lamp 210 comprises an ultraviolet lamp bead (or lamp strip) and a lampshade, and the lampshade covers the outer side surface of the ultraviolet lamp bead to play a role in isolating and protecting the ultraviolet lamp bead and avoid short circuit caused by water permeating into the ultraviolet lamp 210. Here, the lamp cover is made of a quartz glass material.

In this embodiment, the ultraviolet sterilization module 200 is disposed in the flow passage, and the size of the ultraviolet sterilization module 200 is smaller than the inner diameter of the module housing 100, so as to leave a space for water to flow between the outer peripheries of the ultraviolet sterilization module 200 and the heat dissipation member 240 and the module housing 100. Accordingly, as shown in fig. 4, the middle of the cylinder section 110 is provided with a holding frame 111, the ultraviolet sterilization module 200 is held in the holding frame 111, and a gap formed between the holding frame 111 and the inner wall of the cylinder section 110 is used as a space channel through which water flows, which is equivalent to one of the components of the flow channel.

In fig. 4, the clamping frame 111 is a flat circular frame suspended in the middle of the cylinder section 110, a frame slot 1111 for clamping the uv sterilization module 200 is disposed in the middle, and the frame slot 1111 axially penetrates through the clamping frame 111, so that after the uv sterilization module 200 is fixed to the clamping frame 111, the uv lamp 210 can face the inner space of the module housing 100 through the slot to irradiate the water flow passing through the channel. The retaining frame 111 further includes a plurality of fixing arms 1112 extending from the outer periphery to the module housing 100, the fixing arms 1112 are used to connect the retaining frame 111 and the module housing 100, so as to fix the retaining frame 111, fig. 4 shows that the retaining frame 111 is provided with 4 fixing arms 1112, the included angle between the fixing arms 1112 is 90 °, and the space between the adjacent fixing arms 1112 can be used for water flow.

Optionally, in order to reduce the occurrence of water seepage from the clamping frame 111 to the ultraviolet sterilization module 200, one or more first sealing rings 410 are further sleeved on the periphery of the ultraviolet sterilization module 200, as shown in fig. 3, the first sealing rings 410 may be used to seal gaps between the components of the ultraviolet sterilization module 200 and the clamping grooves, so as to block water from permeating into the ultraviolet sterilization module 200 (especially the ultraviolet lamp 210).

In an embodiment, the first sealing ring 410 is a ring structure with elasticity, and may be made of rubber or the like.

In some optional embodiments, when the ultraviolet sterilization module 200 operates, the ultraviolet lamp 210 and the circuit board 220 generate a large amount of heat due to their own resistance, which causes the temperature of the ultraviolet sterilization module 200 to rise, and therefore, in order to dissipate heat from these self-heating devices, the ultraviolet sterilization module 200 is further provided with a heat dissipation member 240, the heat dissipation member 240 is in heat conduction contact with one or more devices, the heat is transferred to the heat dissipation member 240 in a direct or indirect conduction manner, meanwhile, at least part of the heat dissipation member 240 is exposed in the overflow channel and can be in contact with a water flow, so that the heat can be transferred from the heat dissipation member 240 into the water, and thus, the heat generated by the operation of the ultraviolet sterilization module 200 can be continuously transferred along with the continuous flow of the water flow, so that the ultraviolet sterilization module 200 can be always taken away in a lower temperature state, and the stability of the operating state of the ultraviolet sterilization module 200 and the service life thereof are effectively guaranteed.

Optionally, the heat dissipation member 240 is disposed adjacent to the circuit board 220, that is, the heat dissipation member 240 is disposed on the backlight side of the ultraviolet sterilization module 200, and therefore is not located in the irradiation region of the ultraviolet lamp 210, and does not block ultraviolet light. In the example, the circuit board 220 is configured as a circular sheet structure, and the heat sink 240 is configured as a pie-shaped heat sink base, and one side of the heat sink base abuts against the circuit board 220, so that the two have a large heat-conducting contact area; the peripheral surface and/or the side surface back to the backlight side of the heat dissipation base are exposed in the overflowing channel and can be in contact with water flow and conduct heat.

In the example, the ultraviolet sterilization module 200 is disposed near the first water inlet 121, so that the heat dissipation base is impacted by water flowing from the first water inlet 121, the water flow rate is high, the temperature is low, and the heat dissipation effect is high; correspondingly, the heat dissipating member 240 is located at a side close to the first water inlet 121, that is, the ultraviolet lamp 210 of the ultraviolet sterilization module 200 is disposed toward the first water outlet 131. In this implementation, a side surface and a part of the outer peripheral surface of the heat dissipation base opposite to the circuit board 220 can both contact with water flow, so as to achieve a better heat conduction and dissipation effect.

In some alternative embodiments, the heat dissipation base is made of a metal material, such as copper, iron, aluminum, and alloys thereof, and the metal material has a high thermal conductivity, so that heat at the circuit board 220 can be quickly conducted into water, thereby reducing heat accumulation.

Optionally, the inner diameter of the sterilization inner cavity 310 of the module inner housing 300 is larger than the aperture of the second water outlet 322, and the sectional area of the water flow path is reduced, so that the water flow resistance can be increased to delay the flow rate of water flowing out of the sterilization inner cavity 310, and the water flow can be irradiated by the ultraviolet sterilization module 200 for a longer time to perform sufficient sterilization.

Optionally, the second water inlet 321 of the module inner shell 300 is configured as a petal-shaped structure formed with a plurality of water blocking blocks at intervals along the circumferential direction, and a space between adjacent water blocking blocks is available for water flow to pass through; this configuration of the second water inlet 321 can slow down the flow rate of the water flowing into the sterilization chamber 310.

Optionally, in order to improve the sealing performance between the module inner housing 300 and the module outer housing 100, one or more second sealing rings 420 are further sleeved on the outer periphery of the module inner housing 300, and the second sealing rings 420 are used for blocking a gap between the module inner housing 300 and the module outer housing 100, so that water flow can only flow from the module inner housing 300 to the first water outlet 131 of the module outer housing 100, and thus all water flow can be sterilized by ultraviolet irradiation when flowing through the module inner housing 300.

Suitably, one or more sealing slots 330 are formed on the outer periphery of the module inner housing 300 for receiving and retaining the second sealing ring 420.

Optionally, the module inner housing 300 is made of quartz glass.

Since the quartz glass has the characteristics of good light transmission performance, good thermal stability, good electrical insulation performance, high temperature resistance, corrosion resistance and the like, and the material of the module inner shell 300 is the quartz glass, on one hand, the sterilization effect of the sterilization device can be effectively improved due to the good light transmission performance; on the other hand, can make the module of disinfecting be applicable to the hot water pipeline, also can be applicable to the cold water pipeline, and then the module inner shell 300 adopts quartz glass can improve the flexibility of the module of disinfecting use scene effectively, satisfies user's different user demands. In addition, the module inner housing 300 is made of quartz glass, so that the service life of the sterilization module can be effectively prolonged.
