Description

Technical Field

[0001] This invention relates to the field of fluid disinfection and sterilization technology, specifically to a freeze-proof, crack-resistant water sterilization device. Background Technology

[0002] An ultraviolet (UV) water sterilization module is a device that uses physical methods to continuously sterilize flowing liquids. Its working principle mainly involves the liquid entering the sterilization module through a conveying system, undergoing UV sterilization treatment inside the module, and then being output as a fluid.

[0003] The internal water flow channel of existing UV water sterilization modules is generally a quartz tube. When used in cold regions, the fluid inside the quartz tube freezes and its volume increases, causing the quartz tube to expand to a certain extent. The fasteners that install the quartz tube do not have enough space to allow for the volume change of the quartz tube, which will cause the quartz tube to freeze and crack. This makes the antifreeze performance of existing UV water sterilization modules poor and unable to meet users' requirements for antifreeze cracking of UV water sterilization modules. Summary of the Invention

[0004] This invention addresses the technical problem of existing ultraviolet water sterilization modules where the quartz tube is prone to freezing and shrinkage, and easily breaks when squeezed by corresponding fasteners. It proposes a freeze-crack-resistant water sterilization device. By optimizing the mounting fasteners for the quartz tube, the probability of breakage and damage is reduced.

[0005] To achieve the above objectives, the following solution is provided: a freeze-proof and crack-resistant water sterilization device, comprising an installation sleeve, a sterilization module and a quartz tube, wherein the sterilization module is installed on the installation sleeve and the quartz tube is installed inside the installation sleeve, and further comprising a sealing end cap, wherein sealing end caps are installed at both ends of the quartz tube and the sealing end caps are located between the end of the quartz tube and the end of the machine body; The sealing end cap includes a base pad, a top seat, a sealing mechanism, and an inner support mechanism. The top seat is provided on one side of the base pad, and the top seat abuts against the inner end of the mounting sleeve. A connecting hole is provided at the top seat. The included angle space between the top seat and the base pad forms a second compression chamber. The inner support mechanism is provided on the other side of the base pad. The sealing mechanism is provided at the edge of the side of the base pad where the inner support mechanism is provided. The end of the quartz tube is inserted between the sealing mechanism and the inner support mechanism. The inner support mechanism includes a connecting sleeve and an inner support ring. One end of the connecting sleeve is fixedly connected to the base pad, and the other end of the connecting sleeve is provided with an inner support ring. The space between the inner support ring, the connecting sleeve, and the base pad forms a first compression cavity. The inner support ring is adapted to the inner diameter of the quartz tube. The inner support ring is inserted into the quartz tube and abuts against the inner wall of the quartz tube. The inner side of the connecting sleeve is a through hole, which is connected to the connecting hole. The sealing mechanism includes a sealing sleeve and several sealing rings. The sealing sleeve is fixedly installed at the base pad. The inner side wall of the sealing sleeve abuts against the outer side wall of the quartz tube. Several sealing rings are provided on the outer side wall of the sealing sleeve. The sealing rings are separated from each other in pairs. The sealing rings abut against the inner wall of the mounting sleeve. The space between the two sealing rings forms a third compression chamber.

[0006] Furthermore, the sterilization module includes a mounting housing and an ultraviolet lamp plate. The mounting housing is fixedly installed on the outside of the mounting sleeve, and the ultraviolet lamp plate is installed on the mounting housing. A number of ultraviolet lamp beads are provided on the ultraviolet lamp plate, and the ultraviolet lamp beads are located at the lamp holes on the side wall of the mounting sleeve.

[0007] Furthermore, one end of the mounting sleeve is provided with a first connector, and the other end of the mounting sleeve is provided with an external thread. The end cap is fixed to the end of the mounting sleeve by screwing on the external thread. The end cap is provided with a second connector, and the connecting hole of the top seat is in communication with the first connector or the second connector.

[0008] Furthermore, the mounting sleeve is equipped with a reflective mechanism for reflecting ultraviolet rays.

[0009] Furthermore, the reflective mechanism is a reflective layer, which is disposed on the inner side wall of the mounting sleeve.

[0010] Furthermore, the reflecting mechanism is an emitting tube with a smooth reflecting surface on the inside. The emitting tube is sleeved on the outside of the quartz tube and has a slot at the emitting tube that matches the ultraviolet lamp hole of the ultraviolet lamp plate.

[0011] Furthermore, the base pad, top seat, inner support mechanism, and sealing mechanism are integrally formed and are all made of elastic sealing material.

[0012] The working principle and advantages of this invention are as follows: This anti-freezing and cracking water sterilization device installs the quartz tube in the installation sleeve through two sealing end caps. By optimizing the mechanism of the sealing end caps, multiple compression chambers are provided at the sealing end caps.

[0015] The following detailed explanation illustrates the specific implementation methods: Implementation 1, such as Figures 1 to 4 As shown: A freeze-proof, crack-resistant water sterilization device includes an installation sleeve 1, a sterilization module, and a quartz tube 7. The sterilization module is installed on the installation sleeve 1 and emits sterilization light. The quartz tube 7 is installed inside the installation sleeve 1 and is a light-transmitting tube. The quartz tube 7 is used for fluid flow and is irradiated by the sterilization light from the sterilization module. The device also includes sealing caps 8. Sealing caps 8 are installed at both ends of the quartz tube 7 and are located between the end of the quartz tube 7 and the end of the device body. The sealing caps 8 are used to fix the quartz tube 7 and seal the gap between the quartz tube 7 and the installation sleeve 1, as well as reduce the risk of the quartz tube 7 freezing and shrinking and being crushed by other parts. The sealing end cap 8 includes a base pad 81, a top seat 82, a sealing mechanism, and an inner support mechanism. The base pad 81, top seat 82, inner support mechanism, and sealing mechanism are integrally molded and made of elastic sealing materials such as silicone, which have a certain degree of elasticity and softness.

[0016] A top seat 82 is provided on one side of the base pad 81. The top seat 82 abuts against the inner end of the mounting sleeve 1, so that the base pad 81 is separated from the inner end wall of the mounting sleeve 1. A connecting hole 83 is provided at the top seat 82 for fluid flow. The included angle space between the top seat 82 and the base pad 81 forms a second extrusion chamber 810. When the quartz tube 7 contracts or expands due to temperature difference, the second extrusion chamber 810 forms a certain buffer space to adapt to the contraction and expansion of the quartz tube 7. An inner support mechanism is provided on the other side of the base pad 81. A sealing mechanism is provided at the edge of the side of the base pad 81 where the inner support mechanism is provided. The end of the quartz tube 7 is inserted between the sealing mechanism and the inner support mechanism, so that the sealing mechanism and the inner support mechanism work together to seal and fix the quartz tube 7 at the sealing end cap 8. The inner support mechanism includes a connecting sleeve 86 and an inner support ring. One end of the connecting sleeve 86 is fixedly connected to the base pad 81, and the other end of the connecting sleeve 86 is provided with an inner support ring 88. The space between the inner support ring 88, the connecting sleeve 86, and the base pad 81 forms a first compression chamber 89. The first compression chamber 89 forms a certain buffer space to adapt to the expansion and contraction of the quartz tube 7. The inner support ring 88 is adapted to the inner diameter of the quartz tube 7. The inner support ring 88 is inserted into the quartz tube 7 and abuts against the inner wall of the quartz tube 7, so that the inner support ring 88 can seal the gap between the quartz tube 7 and the sealing end cap 8. The inner side of the connecting sleeve is a through hole 87, which is connected to the connecting hole 83, thereby making the quartz tube 7 connected to the through hole 87 and the connecting hole 83. The sealing mechanism includes a sealing sleeve 84 and several sealing rings 85. The sealing sleeve 84 is fixedly installed at the base pad 81. The inner side wall of the sealing sleeve 84 abuts against the outer side wall of the quartz tube 7, further sealing the gap between the quartz tube 7 and the sealing end cap 8. Several sealing rings 85 are provided on the outer side wall of the sealing sleeve 84. The sealing rings 85 are separated in pairs. The sealing rings 85 abut against the inner wall of the mounting sleeve, improving the sealing performance between the sealing end cap 8 and the mounting sleeve 1. The space between the two sealing rings 85 forms a third compression chamber 811. The third compression chamber 811 forms a certain buffer space to adapt to the expansion and contraction of the quartz tube 7.

[0017] The sterilization module includes a mounting housing 2 and an ultraviolet lamp plate 3. The mounting housing 2 is fixedly installed on the outside of the mounting sleeve, and the ultraviolet lamp plate 3 is installed on the mounting housing 2. The mounting housing 2 is used to fix the ultraviolet lamp plate 3 to the mounting sleeve 1. The ultraviolet lamp plate 3 is equipped with several ultraviolet lamp beads, which can emit ultraviolet light. The ultraviolet lamp beads can produce 270nm ultraviolet light. The ultraviolet lamp beads are located in the lamp hole 11 on the side wall of the mounting sleeve, so that the ultraviolet lamp beads can irradiate the quartz tube 7 through the lamp hole 11 to fully irradiate the flowing water. The 270nm ultraviolet light has a strong bactericidal effect on bacteria. The 270nm ultraviolet light is used to kill bacteria in the water to achieve the effect of sterilization and purification.

[0018] One end of the mounting sleeve is provided with a first connector 4, which is connected to the corresponding fluid pipeline. The other end of the mounting sleeve is provided with an external thread 12. The end cap 5 is screwed onto the end of the mounting sleeve through the external thread 12, so that one end of the mounting sleeve 1 is detachable, which facilitates the disassembly and assembly of the quartz tube 7 and the sealing end cap 8. The end cap 5 is provided with a second connector 6, which is connected to the corresponding fluid pipeline. The connecting hole 83 of the top seat 82 is connected to the first connector 4 or the second connector 6, thereby forming a passage inside the device, and the fluid can flow in the passage formed by the first connector 4, the quartz tube 7 and the second connector 6.

[0019] The mounting sleeve 1 is equipped with a reflective mechanism for reflecting ultraviolet rays. The reflective mechanism can continuously reflect the ultraviolet light generated by the ultraviolet lamp panel 3 within the space where the quartz tube 7 is located, thereby improving the disinfection efficiency.

[0020] The reflective mechanism is a reflective layer, which is located on the inner side wall of the mounting sleeve 1. The reflective layer can be a metal coating or other coating that can reflect ultraviolet light, such as aluminum.

[0021] Example 2, as Figure 5 As shown: The difference between this and Embodiment 1 is that the reflective mechanism is an emitting tube, the inner side of the reflective tube 9 is a smooth reflective surface, the reflective tube 9 can be made of Teflon, or the inner wall contains gold, silver, aluminum or other materials that can reflect ultraviolet light, the emitting tube is sleeved on the outside of the quartz tube 7 and the emitting tube is provided with a slot that matches the ultraviolet lamp hole 11 of the ultraviolet lamp plate 3, so that the light emitted by the ultraviolet lamp bead can smoothly irradiate into the quartz tube 7.

[0022] The specific implementation process is as follows: When using this anti-freezing and cracking water sterilization device, first connect the first connector 4 and the second connector 6 to the corresponding pipeline. When the fluid to be sterilized flows through the quartz tube 7, the ultraviolet lamp beads at the ultraviolet lamp plate 3 emit ultraviolet light. The ultraviolet light shines on the quartz tube 7. Due to the action of the reflection mechanism, the ultraviolet light is continuously reflected and circulated to the quartz tube 7, which can effectively sterilize the fluid flowing through the quartz tube 7.

[0023] If the quartz tube 7 is filled with fluid and the device is operating in a low-temperature environment, the fluid inside the quartz tube 7 will freeze and expand, causing the quartz tube 7 to change accordingly. The first compression chamber 89, the second compression chamber 810, and the third compression chamber 811 at the sealing end cap 8 can provide sufficient buffer space. When the quartz tube 7 compresses the sealing end cap 8, it has sufficient expansion space, which can effectively reduce the risk of the fluid inside the quartz tube 7 freezing and expanding, causing the quartz tube 7 to expand and freeze and crack.

[0024] This anti-freeze and cracking water sterilization device uses two sealing caps 8 to install the quartz tube 7 in the installation sleeve. By optimizing the mechanism of the sealing caps 8, multiple compression chambers are provided at the sealing caps 8. At the same time, the sealing caps 8 are made of elastic sealing materials such as silicone, so that the quartz tube 7 has sufficient buffer space when the fluid inside the quartz tube expands due to freezing, effectively improving the overall anti-freeze and cracking performance of this device.
