Description

Technical Field

[0001] This utility model relates to the field of sterilization and disinfection equipment technology, specifically to a sterilizer with a manual cleaning function. Background Technology

[0002] As people's living standards improve, their requirements for water quality are also increasing. Traditional water treatment methods, such as chlorination and ozone, while capable of sterilization and disinfection to some extent, pose potential risks to human health and the environment. Ultraviolet (UV) sterilization technology, as a non-chemical sterilization method, is gradually gaining attention.

[0003] Ultraviolet (UV) sterilizers emit high-intensity UV radiation, which destroys the DNA structure of bacteria, viruses, and other microorganisms in water, thereby achieving sterilization and disinfection. Compared with traditional chemical sterilization methods, UV sterilizers have advantages such as high sterilization efficiency, no secondary pollution, and simple operation and maintenance. Specifically, refer to Chinese invention patent application number 202410652268.7, which discloses a UV sterilizer with a built-in water pollution control agent. In this sterilizer, multiple UV lamps are inserted inside the UV sterilization housing to sterilize the water flowing through it. In addition, a cleaning component is included; after prolonged use, the surface of the transparent glass tube can be cleaned of limescale using the cleaning cylinder, improving the sterilization effect of the UV lamps.

[0004] In the above structure, the cleaning mechanism and drive components are relatively complex and require drive wheels and traction belts to move along the ultraviolet lamp tubes to achieve automatic cleaning of dirt. However, under the erosion of water flow and strong ultraviolet radiation, the service life and performance of the drive wheels and traction ropes will be severely reduced. Therefore, regular maintenance or replacement of parts is required to ensure the normal use of the cleaning function. However, since these parts are located inside the sterilizer, maintenance and replacement are quite inconvenient, requiring a lot of manpower and resources, resulting in high maintenance costs. Furthermore, in such harsh working conditions, electronic components are prone to instability, leading to abnormal cleaning function. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a sterilizer with manual cleaning function.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A sterilizer with manual cleaning function includes a sterilizer body, a cleaning device, and a drive rod. The sterilizer body has a vertically penetrating mounting cavity and a germicidal lamp tube horizontally arranged within the mounting cavity. The cleaning device is movably sleeved on the outer surface of the germicidal lamp tube. One end of the drive rod extends horizontally from the outside of the sterilizer body into the mounting cavity and connects to the cleaning device. The other end of the drive rod has a push-pull handle. The push-pull handle drives the cleaning device to scrape and clean along the outer surface of the germicidal lamp tube via the drive rod. A sealing assembly is provided at the mating point between the drive rod and the sterilizer body. The sealing assembly includes a sealing gasket and a sealing cap sleeved on the drive rod. The sealing cap presses the sealing gasket tightly against the mating point between the drive rod and the sterilizer body to form a seal.

[0008] In this invention, one side of the mounting cavity is provided with an opening communicating with the outside. An annular mounting plate extends outward from the edge of the opening. The mounting plate is provided with multiple positioning rods perpendicular to the surface of the mounting plate. The sterilizer body also includes a sealing plate. After being positioned by the positioning rods, the sealing plate is tightly fitted with the mounting plate to seal the opening. The middle part of the sealing plate is provided with a mounting hole for the sterilizing lamp tube to extend into the mounting cavity and a movable hole for the drive rod to pass through. The sealing assembly is located at the movable hole.

[0009] Furthermore, the movable hole has a sealing seat protruding outward from the outer surface of the sealing plate and a sealing cavity recessed inward from the outer surface of the sealing plate. The sealing gasket is accommodated in the sealing cavity. The inner side of the sealing seat has an internal thread for connecting the sealing cover. The sealing cover has an external thread that engages with the internal thread. After the sealing cover is tightened onto the sealing seat through the external thread, the sealing gasket is pressed into the sealing cavity to form a seal.

[0010] Furthermore, the radius of the sealing cavity is the same as the radius of the sealing gasket under normal conditions, the depth of the sealing cavity is less than the thickness of the sealing gasket under normal conditions, the inner ring of the sealing gasket is provided with a V-shaped opening, the V-shaped opening is arranged around the inner side of the sealing gasket, and the two sides of the sealing gasket are also provided with outward protruding pressing parts. When the sealing cap is tightened, it presses the V-shaped opening and causes the sealing gasket to expand radially outward.

[0011] In this invention, the inner surface of the sealing plate is provided with a sealing seat with the same structure as the outer surface at the position of the movable hole, and the sealing assembly is provided with two sets and symmetrically arranged on the inner and outer sealing seats respectively.

[0012] In this utility model, the cleaning device includes a movable frame connected to a drive rod, a cleaning ring detachably mounted on the movable frame, and a cleaning cotton embedded inside the cleaning ring. The cleaning ring is sleeved on the germicidal lamp tube, and the cleaning cotton is tightly attached to the outer surface of the germicidal lamp tube. The drive rod drives the cleaning ring to move along the germicidal lamp tube through the movable frame.

[0013] Furthermore, the movable frame is equipped with multiple cleaning rings, each with a corresponding cleaning cotton embedded in it.

[0014] Furthermore, the drive rod is connected to the side of the movable frame, and the upper and lower parts of the mounting cavity are respectively provided with positioning guide rods parallel to the germicidal lamp tube. The upper and lower parts of the movable frame are slidably engaged with the positioning guide rods, and the drive rod drives the movable frame to move along the direction of the positioning guide rods.

[0015] This utility model has the following advantages and beneficial effects:

[0016] A cleaning device is installed inside the mounting cavity and fitted onto the germicidal lamp tube to clean surface dirt. It is connected to the cleaning device via a drive rod that extends into the mounting cavity. During cleaning, the cleaning device can be moved back and forth along the germicidal lamp tube periodically by pushing and pulling the handle. This structure is simpler and more convenient, eliminating the need for frequent maintenance of the drive rod and reducing maintenance costs. In addition, there is only a mechanical connection between the cleaning device and the drive rod, which has high connection strength and will not be damaged by water erosion or strong ultraviolet light, thus making it more stable.

[0027] like Figures 1 to 6 As shown, this embodiment discloses a sterilizer with a manual cleaning function, including a sterilizer body 1, a cleaning device 2, and a drive rod 3. The sterilizer body 1 has a vertically penetrating mounting cavity 10 and a sterilizing lamp 11 horizontally disposed within the mounting cavity 10. The cleaning device 2 is movably sleeved on the outer surface of the sterilizing lamp 11. One end of the drive rod 3 extends horizontally from the outside of the sterilizer body 1 into the mounting cavity 10 and connects to the cleaning device 2. The other end of the drive rod 3 has a push-pull handle 31. The handle 31 can drive the cleaning device 2 to scrape along the outer surface of the germicidal lamp tube 11, thereby achieving a cleaning effect. However, when the drive rod 3 is activated, water leakage is likely to occur at the joint between the drive rod 3 and the sterilizer body 1. Therefore, a sealing component 12 is provided at the joint between the drive rod 3 and the sterilizer body 1. The sealing component 12 includes a sealing gasket 121 and a sealing cap 122 fitted on the drive rod 3. The sealing cap 122 presses the sealing gasket 121 tightly at the joint between the drive rod 3 and the sterilizer body 1 to form a seal.

[0028] In this embodiment, to facilitate the installation of the cleaning device 2 and the drive rod 3, an opening communicating with the outside is provided on one side of the mounting cavity 10. An annular mounting plate 13 extends outward from the edge of the opening. The mounting plate 13 is provided with multiple positioning rods 130 perpendicular to the plate surface. A sealing plate 14 is also provided at the opening. After the sealing plate 14 is positioned and installed by the positioning rods 130, it fits tightly with the mounting plate 13 to form a seal. The middle part of the sealing plate 14 is provided with a mounting hole 140 for the germicidal lamp tube 11 to extend into the mounting cavity 10 and a movable hole 141 for the drive rod 3 to pass through. The sealing assembly 12 is provided at the movable hole 141.

[0029] Specifically, the movable hole 141 has a sealing seat 142 protruding outward from the outer surface of the sealing plate 14, and a sealing cavity 143 recessed inward from the outer surface of the sealing plate 14. The sealing gasket 121 is accommodated in the sealing cavity 143. The inner side of the sealing seat 142 has an internal thread for connecting the sealing cover 122. The sealing cover 122 has an external thread that engages with the internal thread. Obviously, after the sealing cover 122 is tightened by the thread, it presses the sealing gasket 121 into the sealing cavity 143 to form a seal. This seals the gap between the drive rod 3 and the movable rod, preventing water from seeping out.

[0030] Furthermore, to improve the sealing effect, the radius of the sealing cavity 143 is set to be the same as the radius of the sealing gasket 121 under normal conditions, and the depth of the sealing cavity 143 is set to be less than the thickness of the sealing gasket 121 under normal conditions. The inner ring of the sealing gasket 121 is provided with a V-shaped opening 121a, which is arranged around the inner side of the sealing gasket 121. The two sides of the sealing gasket 121 are also provided with outwardly protruding pressing parts 121b. When the sealing cover 122 is tightened, the sealing cover 122 presses the sealing gasket 121 and simultaneously presses the V-shaped opening 121a through the pressing parts 121b to close it. At the same time as the V-shaped opening 121a closes, the sealing gasket 121 as a whole will expand radially outward, so that the sealing gasket 121 fits more tightly between the sealing cavity 143 and the drive rod 3, resulting in a better sealing effect.

[0031] In this embodiment, in order to achieve a sealing effect on both the inner and outer sides of the movable hole 141, a sealing seat 142 with the same structure as the outer surface is provided on the inner surface of the sealing plate 14 corresponding to the position of the movable hole 141. The sealing assembly 12 is provided with two sets and is symmetrically arranged on the inner and outer sealing seats 142 respectively.

[0032] In this embodiment, the cleaning device 2 includes a movable frame 21 connected to the drive rod 3, a cleaning ring 22 detachably mounted on the movable frame 21, and a cleaning cotton 23 embedded inside the cleaning ring 22. The cleaning ring 22 is sleeved on the germicidal lamp tube 11, and the cleaning cotton 23 is tightly attached to the outer surface of the germicidal lamp tube 11. The drive rod 3 drives the cleaning ring 22 to move along the germicidal lamp tube 11 through the movable frame 21.

[0033] Furthermore, to improve the cleaning effect, multiple cleaning rings 22 are installed on the movable frame 21, and a cleaning cotton 23 is installed on each cleaning ring 22. By setting multiple cleaning rings 22 and cleaning cotton 23, the drive rod 3 can clean the outer surface of the germicidal lamp tube 11 multiple times with one push and pull, thereby improving the cleaning efficiency. Specifically, the drive rod 3 is connected to the side of the movable frame 21. Therefore, in order to improve the stability of the movable frame 21 when it moves, positioning guide rods 15 parallel to the germicidal lamp tube 11 are respectively provided in the upper and lower parts of the mounting cavity 10. The upper and lower parts of the movable frame 21 are slidably engaged with the positioning guide rods 15. When the drive rod 3 is driven, the movable frame 21 can only move along the direction of the positioning guide rods 15, thereby avoiding the occurrence of deflection force. In addition, the positioning effect of the positioning guide rods 15 can also make the middle part of the germicidal lamp tube 11 form a support in the mounting cavity 10, preventing the germicidal lamp tube 11 from bending due to excessive water pressure.

[0034] In this embodiment, the sterilizer body 1 is also provided with a plurality of pre-installation ports 16 for pre-installing monitoring elements. After the monitoring elements are installed through the pre-installation ports 16, the working condition inside the sterilizer body 1 can be monitored, such as temperature monitoring, water pressure monitoring, and light intensity monitoring of the sterilizing lamp tube 11.

[0035] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
