Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a disinfection device for the water storage tank of a pure water instrument. Background Technology

[0002] A pure water system uses a series of water treatment technologies to remove ions, impurities, bacteria, and other contaminants from water, producing high-purity water. Pure water systems are widely used in laboratories, medical facilities, and industrial fields, especially in applications requiring high-purity water, such as chemical analysis, pharmaceutical production, and electronics manufacturing. The water tank disinfection device in a pure water system is typically used to ensure the hygiene and purity of the water in the tank, preventing the growth of microorganisms or bacteria. The main function of this disinfection device is to clean and disinfect the water tank using physical or chemical means to maintain the high quality of the pure water.

[0003] Patent CN2579878Y discloses a pressure storage tank for a pure water machine equipped with an ultraviolet sterilizer. Pure water produced by the pure water machine is sterilized by the ultraviolet sterilizer before entering the pressure storage tank. Pure water coming out of the pressure storage tank and being discharged from the gooseneck faucet is also sterilized by the ultraviolet sterilizer. This double ultraviolet sterilization process eliminates the risk of bacteria in drinking pure water caused by secondary contamination from the pipes behind the pure water machine's outlet and the pressure storage tank, making drinking pure water more hygienic and safer.

[0004] In the above solution, although the ultraviolet light sterilization avoids secondary pollution of the pressure storage tank, there is an "O" ring between the tightening nut, the ultraviolet reflector sleeve, and the single-opening quartz glass tube. The quartz glass tube is relatively sealed, and the ultraviolet sterilizer is in a sealed environment where heat that is not easily dissipated gradually accumulates. This will eventually lead to excessively high temperature inside the quartz glass tube, reducing the service life of the ultraviolet sterilizer. It may also affect the airtightness of the container due to the deformation of the sealing parts caused by heat. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems by providing a water purification device for the water storage tank of a pure water system that can solve the above-mentioned technical issues.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water purification system's water tank disinfection device includes a water tank cover and a disinfection lamp source.

[0014] In the disinfection device for the water storage tank of the pure water instrument, the through holes opened on the protective cover include an air inlet hole and an air outlet hole. The air inlet hole is located on the side of the protective cover and corresponds to the heat dissipation fan, and the air outlet hole is located on the end face of the protective cover and corresponds to the heat dissipation fin.

[0015] In the pure water instrument water tank disinfection device, the heat sinks are radially distributed with the cooling fan shaft as the axis, and the gaps between adjacent heat sinks connect the air intake side of the cooling fan to form an air intake channel.

[0016] In the pure water instrument water tank disinfection device, a wire fixing bracket is provided on the cover surface of the water tank, and the wiring of the disinfection lamp source and the heat dissipation component is fixed on the wire fixing bracket.

[0017] The advantages of this utility model are:

[0018] The disinfection lamp source is equipped with a heat dissipation component for heat exchange, which greatly reduces the working environment of the disinfection lamp source, effectively improving its service life and operational stability.

Detailed Implementation

[0023] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the utility model. However, the utility model is not limited to these embodiments.

[0024] like Figures 1-3 As shown, the water tank disinfection device of the pure water instrument includes a water tank cover 1 and a disinfection lamp source 2. The disinfection lamp source 2 is installed in the mounting groove 11 opened axially in the water tank cover 1. A heat dissipation component 3 is provided on the disinfection lamp source 2. At least a part of the heat dissipation component 3 extends out of the mounting groove 11 to the side of the cover of the water tank cover 1 and is covered by a protective cover 4. The protective cover 4 has several through holes to allow airflow circulation to the heat dissipation component 3.

[0025] The disinfection lamp source is equipped with a heat dissipation component for heat exchange, which greatly reduces the working environment of the disinfection lamp source, effectively improving its service life and operational stability. Furthermore, airflow circulation is created through the openings in the protective cover, efficiently and directionally expelling heat from the device. Simultaneously, the lamp source holder slots inside the device and the locking and limiting mechanisms of the external protective cover prevent excessive vibration of the heat dissipation component during rotation, ensuring stable operation and reducing operating noise.

[0026] In this embodiment, a support ring 12 is provided on the inner wall of the mounting groove 11, and an annular lamp source holder 5 is provided on the support ring 12. The disinfection lamp source 2 is located in the inner circle of the lamp source holder 5 and the light source is emitted from the bottom side of the water tank cover 1.

[0027] The support ring is used to support and fix the lamp holder bracket, ensuring that the lamp is in the correct position. The inner ring of the lamp holder bracket mates with the lamp, ensuring that the lamp is stably fixed and emitted from the bottom of the cover, guaranteeing the effective illumination area and stability of the lamp, and ensuring its accurate positioning and reliability during use.

[0028] In this embodiment, the outer ring of the lamp source holder 5 is provided with threads that mate with the inner wall of the mounting slot 11, and the inner ring of the lamp source holder 5 is provided with a plurality of support feet 51 to suspend the disinfection lamp source 2 in the lamp source holder 5.

[0029] The outer thread of the lamp holder slot mates with the inner wall of the mounting slot and is fixed by a rotating mechanism to ensure the stability of the lamp holder. The support feet are designed to suspend the lamp source, avoiding direct contact and reducing heat concentration. The support feet also ensure even heat dissipation, preventing localized overheating, which helps extend the equipment's lifespan and improve disinfection efficiency.

[0030] In this embodiment, a light-transmitting lens 52 is provided on the support ring 12, which abuts against the end face of the lamp source holder 5, and a sealing ring 53 is provided between the light-transmitting lens 52 and the support ring 12 for sealing.

[0031] A sealing ring is used to seal the light-transmitting lens and the supporting ring, preventing moisture or dust from entering and thus protecting the disinfection lamp source. The light-transmitting lens helps improve light transmittance, enhancing the disinfection effect, while the sealing ring effectively prevents external contamination, ensuring disinfection effectiveness while extending the equipment's lifespan.

[0032] Among them, the light-transmitting lens 52 is made of quartz glass, which has the characteristics of high temperature resistance, low expansion coefficient, thermal shock resistance, chemical stability and good electrical insulation performance.

[0033] In this embodiment, a limiting block 54 extending outward is provided on the end face of the lamp source holder 5, and the limiting block 54 abuts against the cover surface of the water storage tank cover 1.

[0034] The limiting block is used to restrict the installation position of the lamp holder bracket and prevent it from moving axially during installation. By abutting against the cover surface, the limiting block helps to fix the position of the lamp holder bracket and also serves as a leverage point for screwing the lamp holder bracket 5 into place. The limiting block ensures the stability of the lamp installation position and prevents changes in the lamp position due to vibration or external forces during use.

[0035] In this embodiment, the protective cover 4 is detachably fixed to the cover surface of the water tank cover 1 and its inner wall axially abuts against the heat dissipation component 3, and the disinfection lamp source 2 and the mounting through groove 11 are coaxially fixed in the lamp source base groove 5.

[0036] The protective cover is connected to the water tank cover via slots or threads, allowing for easy disassembly for cleaning or replacement. The inner wall of the protective cover presses and secures the heat dissipation components, preventing them from becoming loose.

[0037] In this embodiment, the heat dissipation component 3 includes a heat dissipation fan 31 and a heat sink 32. The heat sink 32 is connected to the backlight end of the disinfection lamp source 2 and is arranged at intervals around the air intake side of the heat dissipation fan 31.

[0038] The combination of a cooling fan and heatsinks effectively guides airflow and increases heat dissipation. The closely spaced heatsinks cover the intake side of the cooling fan, ensuring even airflow and improving heat dissipation. This cooling structure enhances heat dissipation efficiency, ensuring that the disinfection lamps will not experience performance degradation or damage due to overheating during prolonged operation.

[0039] In this embodiment, the through holes opened on the protective cover 4 include an air inlet through hole 41 and an air outlet through hole 42. The air inlet through hole 41 is located on the side of the protective cover 4 and corresponds to the cooling fan 31, while the air outlet through hole 42 is located on the end face of the protective cover 4 and corresponds to the heat sink 32.

[0040] The air inlet vent aligns with the air intake side of the cooling fan, ensuring unobstructed entry of outside air. The air outlet vent is located at the other end of the protective cover, aligning with the heat release area of ​​the heat sink to facilitate the smooth expulsion of hot air, improving the efficiency of the heat dissipation components, preventing localized heat buildup, and thus extending the lifespan of the equipment.

[0041] In this embodiment, the heat sinks 32 are radially distributed with the shaft of the cooling fan 31 as the axis, and the gaps between adjacent heat sinks 32 connect the air intake side of the cooling fan 31 to form an air intake channel.

[0042] The heatsink structure facilitates smoother airflow, creating an effective air intake channel. The spacing between adjacent heatsinks ensures unobstructed airflow, enhancing heat dissipation, optimizing airflow paths, improving cooling efficiency, and reducing the risk of system overheating.

[0043] In this embodiment, a wire fixing bracket 13 is provided on the cover surface of the water tank cover 1, and the wiring of the disinfection lamp source 2 and the heat dissipation component 3 is fixed on the wire fixing bracket 13.

[0044] The cable holder secures the cable to the cover of the water tank using a slot or fixing bolts, preventing the cable from becoming loose or short-circuiting. The cable holder ensures the stability of the power line and prevents poor contact caused by vibration or improper operation, thus improving the safety and stability of the equipment.

[0045] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model.
