Description

Technical Field

[0001] The utility model relates to the technical field of sterilization equipment, in particular to an ultraviolet sterilizer for a water tank. Background Art

[0002] Ultraviolet disinfection, also known as ultraviolet sterilizer, is a lamp that uses the bactericidal effect of ultraviolet rays for sterilization. Ultraviolet disinfection lamps radiate short-wave sterilizing ultraviolet rays with a wavelength of 253.7nm (nanometers). Ultraviolet rays in this band have the strongest bactericidal ability and can be used to disinfect water, air, clothing, etc. In addition, the sterilizer can also be used in water tanks to sterilize the water in the water tank. This type of sterilizer will be waterproof, but this type of sterilizer cannot protect the entire device and cannot be placed in the water. For example, for some large water tanks, if the size of the sterilizer is not enough, the entire sterilizer cannot be placed in the water to sterilize the water in the entire water tank, and the effect is poor. In addition, if effective protection is not done, the sterilizer may fall into the water and be damaged.

[0003] Based on the above problems, there is an urgent need for a sterilizer that can achieve all-round waterproofing. Utility Model Content

[0022] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0023] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0024] See also Figure 1-Figure 4The embodiment of the present application discloses an ultraviolet sterilizer for a water tank. Although some waterproof designs are designed for the existing ultraviolet sterilizer for water tanks, the entire ultraviolet sterilizer cannot be waterproof, which greatly reduces the sterilization range of the ultraviolet sterilizer. Based on this, the present device has an original lamp holder 5, a cable 1 electrically connected to the lamp holder 5, and an ultraviolet sterilization lamp tube 9 fixedly connected to the lamp holder 5. Glue particles are embedded on the outside of the cable 1 to achieve protection components on both sides. In the design of diving equipment, the cable 1 has a Flexible, difficult to seal reliably, the protection component includes an inner sleeve 14 passing through the cable 1 in sequence, a sealing head spin-pressed end cap 3 and a lock 2 for fixing the cable 1, the lock 2 is used to fix the cable, the sealing head spin-pressed end cap 3 and the lock 2 are connected by threaded clamps, the outer side of the sealing head spin-pressed end cap 3 is nested with a spin-pressed end cap sealing ring 11 through an annular groove, the sealing head spin-pressed end cap 3 and the inner sleeve 14 have grooves on the opposite sides, the grooves are used to cover the rubber particles, as shown in the figure, the center of the right end face of the spin-pressed end cap is a concave conical surface matching the rubber particle sealing cone surface. When the spin-pressed end cap is tightened, the right conical surface of the spin-pressed end cap will press the convex conical surface on the left side of the rubber particle, and make the rubber particle press the outer circumferential surface of the cable 1 inward to form a seal. At the same time, the rubber particle continues to squeeze to the right, pushing the inner sleeve 14 to the right. The left side of the inner sleeve 14 is also a concave conical surface matching the rubber particle. When the rubber particles are pressed rightward onto the inner sleeve 14, the combined conical surfaces form a seal, and the rubber particles squeeze the circumferential surface of the cable 1 inward to form a seal. The other end of the sealing head spinning end cap 3 is connected to the sealing head seat 7 through a thread. In this way, when the matching O-shaped sealing head spinning end cap 3 is installed in the groove and tightened on the stainless steel sealing head seat 7, a seal can be formed on its outer circumferential surface.

[0025] The inner sleeve 14 has two annular grooves on the outside, and the inner sleeve end face sealing rubber ring 4 and the inner sleeve axial sealing ring 13 are respectively embedded in the annular grooves. Figure 2 As shown in the figure, the spinning end cap sealing ring 11, the inner sleeve end face sealing rubber ring 4, the inner sleeve axial sealing ring 13 and the rubber particles cooperate to form at least two levels of sealing protection on the cable 1 side of the sealing head. The two O-rings assembled on the matching surfaces of the quartz sleeve 10 and the inner hole of the sealing head also form two levels of sealing protection on the sleeve side. We have formed multi-level reliable sealing protection on both the sleeve side and the cable 1 side of the stainless steel sealing head, so that after assembly, it has reliable waterproof ability that can be fully immersed in water and work stably.

[0026] The ultraviolet sterilization lamp 9 is coated with a quartz sleeve 10, and a sealing head seat 7 is fixed to the outside of the quartz sleeve 10 through a quartz sleeve sealing rubber ring 20. The sealing sleeve is used to protect the ultraviolet sterilization lamp 9 inside it to prevent it from being bumped and prevent water in the water tank from entering. At the same time, through the transparent setting of the ultraviolet sterilization lamp 9, the ultraviolet rays of the sterilization lamp can be effectively irradiated into the water body.

[0027] An outward flange is provided at the opening of the quartz sleeve 10 , and the quartz sleeve 10 is embedded in the sealing head seat 7 through the flange, which can effectively prevent the quartz sleeve 10 from sliding outward and effectively waterproof.

[0028] A plastic gasket 15 for protecting the flange and a spring collar 6 for the hole are sequentially arranged above the opening of the quartz sleeve 10. When the sterilizer is placed in a water tank, the spring collar 6 can withstand the water pressure. The spring collar 6 is designed with a plastic gasket 15, and the flexibility of the plastic can protect the flange of the quartz sleeve 10 from being crushed by the metal structure, and the collar can prevent the assembled quartz sleeve 10 from sliding out to the left.

[0029] A silicone cushion pad 17 is provided at the bottom of the ultraviolet sterilization lamp tube 9 . The silicone cushion pad 17 is provided in the quartz sleeve 10 . When the ultraviolet sterilization lamp tube 9 is installed in the quartz sleeve 10 , it can protect the bottom of the ultraviolet sterilization lamp tube 9 .

[0030] In this example, we use a stainless steel card-type quick connector 16 to connect the sterilizer to the box 19. Similarly, the structure of the card-type quick connector 16 is changed, and it can also be designed into many connection structures such as flanges.

[0031] We first machined a conical structure and a sealing ring groove on the outer surface of the quick connector that can match the standard card-type quick connector 16. A through hole was opened along the axis, with a diameter slightly larger than the outer diameter of the sterilizer sealing head and smaller than the diameter of the step on the outer surface of the sealing head. A countersunk hole was opened along the axis on the left side, with a hole diameter slightly larger than the diameter of the step on the outer surface of the sealing head. Several non-through screw holes were evenly distributed on the left end face of the quick connector.

[0032] At the same time, we process a through hole along the central axis of the gland 22, whose diameter is slightly larger than the outer diameter of the sterilizer sealing head and smaller than the diameter of the step on the outer cylindrical surface of the sealing head. A circle of annular bosses are processed on the right side, and its diameter is a clearance match with the countersunk hole on the left side of the quick-connect seat. The height of the boss is just enough to press the O-ring after assembly as shown in the figure above. The gland 22 is also evenly distributed with several through holes that match the positions of the screw holes of the quick-connect seat, so that the gland screws 21 can be used to fix the gland on the quick-connect seat.

[0033] See also Figure 4During installation, we can first use the clamp 18 to fix the quick-connect seat to the box 19, install the O-rings on the sealing conical surfaces on both sides of the outer cylindrical surface step of the sterilizer sealing head, install the sterilizer into the quick-connect seat from left to right, and then use the gland screw 21 to tighten and fix the gland 22 to complete the installation of the sterilizer on the surface of the box 19. At this time, the annular boss of the gland will press the O-ring to form a seal and fix the sterilizer at the same time.

[0034] During maintenance, we do not need to open the clamp 18 to dismantle the entire sterilizer, but only need to remove the spinning end cover of the sterilizer to repair or replace the internal parts of the sterilizer such as the ultraviolet lamp. At this time, the sleeve will not slide out due to the pressure of the liquid in the box because it is blocked by the spring clamp ring. This provides convenience for the maintenance and repair of the sterilizer.

[0035] Unless otherwise specified, the device components involved in the above embodiments are all conventional device components, and the connection methods and control methods involved are all conventional connection methods and control methods unless otherwise specified.

[0036] The present invention has been described in detail above in conjunction with the embodiments. However, those skilled in the art will appreciate that, without departing from the spirit of the present invention, the specific parameters in the embodiments described above may be changed to form a plurality of specific embodiments, which are all within the common variation range of the present invention and will not be described in detail herein.
