Technical Field

[0001] This utility model relates to the field of sterilization and disinfection technology, and specifically to an infrared sterilizer. Background Technology

[0002] Infrared sterilizers, thanks to the sterilization properties of infrared heat energy, are widely used in microbial experiments in settings such as biosafety cabinets, clean benches, and near exhaust fans due to their advantages such as ease of use, simple operation, no open flame, and no environmental pollution. They achieve sterilization by denaturing and coagulating bacterial proteins and inactivating enzymes through high temperatures.

[0003] However, existing infrared sterilizers have the following problems in terms of structural design and function: the installation of the heating inner tank is complicated and requires multiple connectors for fixation, which not only results in low assembly efficiency but may also affect heating stability due to assembly errors.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The following describes the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below. Example 1

[0021] An infrared sterilizer includes: a base 1, a support 2, and a heating mechanism 3. The upper and lower ends of the support 2 are fixedly connected to the upper surface of the base 1 and the lower end of the heating mechanism 3, respectively. The heating mechanism 3 includes a housing 31 and a heating module 32. The housing 31 includes a first housing 311 connected to the upper end of the support 2 and a second housing 312 disposed at both ends of the first housing 311. The first housing 311 has a plurality of heat dissipation holes 3111 through it and threaded portions 3112 at both ends. The second housing 312 is threadedly connected to both ends of the first housing 311. The heating module 32 has a through-type heating inner liner 321, an infrared heater 322, and a second heating inner liner 322 arranged sequentially from the outside to the inside. A wave-shaped gasket 4 is disposed between the end of the first heating inner liner 321 near the support 2 and the second housing 312.

[0022] like Figures 1-4 As shown, during assembly, the second heating liner 323 is first fitted inside the infrared heater 322, and then the entire assembly is installed into the first heating liner 321 to ensure that the axes coincide. Next, a wave-shaped gasket 4 is fitted into the end of the first heating liner 321 near the bracket 2, and the assembled heating module 32 is placed into the first housing 311. Then, the two ends of the second housing 312 are rotated so that they engage with the threaded part 3112 of the first housing 311 until the wave-shaped gasket 4 is compressed, thus completing the sealing and fixing of the heating mechanism 3. Finally, the bottom of the first housing 311 is fixed to the upper end of the bracket 2, and the lower end of the bracket 2 is fixed to the base 1, and the electrical connection of each component is completed, thus completing the overall assembly.

[0023] When in use, after the power is turned on, the infrared heater 322 is powered on and heats up. The heat is conducted to the internal heating zone through the heating inner tank 323. The instruments to be sterilized are placed in through the heating module 32 and sterilized under the action of infrared radiation and high temperature. During operation, the heat dissipation hole 3111 dissipates excess heat to avoid overheating of the shell. After heating is completed, the circuit board automatically cuts off the heating power and the equipment stops working.

[0024] The second housing 312 of this utility model is connected to the first housing 311 by threads, and the heating module 32 is quickly fixed with the corrugated gasket 4. Compared with the traditional multi-step installation method, the assembly efficiency is improved by 40%, and it is convenient for later disassembly and maintenance. The corrugated gasket 4 can compensate for assembly errors through its own elasticity, ensuring that the heating module 32 does not shake in the first housing 311, while reducing the damage of vibration to the infrared heater 322 and extending its service life. The double heating inner liner (ceramic + quartz glass) enhances the heat insulation effect, and the heat dissipation hole 3111 prevents the housing from overheating.

[0025] As a further preferred embodiment, it also includes a support frame 5, which includes a positioning ring 51 sleeved on the outer side of the housing 311, a support rod 52 fixedly disposed on the side end of the positioning ring 51, and an adjusting bracket 53 disposed on the support rod 52. The adjusting bracket 53 includes a mounting part 531 disposed on the support rod 52 and a support part 532 that is damped and slidably disposed on the mounting part 531.

[0026] Specifically, during assembly, the positioning ring 51 is fixed at a suitable position on the housing 311. According to the length of the instrument to be sterilized, the mounting part 531 is slid to the corresponding scale, and then the support part 532 is pushed to support the middle of the instrument, thus completing the support and positioning. This prevents the front end from drooping and the center of gravity from shifting due to the instrument being too long, and prevents the instrument from slipping or colliding with the inner wall of the heating module 32 during operation. At the same time, the sliding adjustment of the mounting part 531 along the support rod 52 can adapt to instruments of different lengths, and the damping sliding of the support part 532 can adapt to rods of different diameters. Combined with the silicone anti-slip design of the arc-shaped support plate, it can stably support experimental instruments of various specifications without the need to replace the support components.

[0027] Alternatively, a locking hole is provided through the positioning ring 51, and a locking pin can be inserted into the locking hole. The locking pin can be inserted into any of the heat dissipation holes 3111 to limit the positioning ring 51.

[0028] Furthermore, the positioning ring 51 is detachably connected to the housing 311, and can be removed when not in use, without increasing the storage volume of the equipment, making it suitable for use in confined spaces such as biosafety cabinets.

[0029] As a further preferred embodiment, the heating inner liner 323 is provided with a positioning hole 3231 at the middle of one end near the support 2.

[0030] Specifically, the relative displacement between the infrared heater 322 and the heating inner tank 323 is limited by mechanical positioning to ensure that the two remain coaxial under high-temperature working conditions, avoiding misalignment caused by thermal expansion and contraction and reducing heat conduction loss.

[0031] As a further preferred embodiment, a counterweight 11 is provided inside the base 1.

[0032] Specifically, when the heating mechanism 3 is tilted or long instruments to be sterilized are placed, the counterweight 11 can lower the overall center of gravity of the equipment, prevent tipping, and improve the anti-tipping ability.

[0033] As a further preferred embodiment, a display control module 6 is provided on the base 11, and the display control module 6 is electrically connected to the heating mechanism 3 through a control center.

[0034] Specifically, a display control module 6 is embedded on the upper surface of the base 1. It is electrically connected to the control center built into the housing 311 via wires. The control center and the infrared heater 322 form a closed-loop control. During use, the sterilization time and target temperature are set by touch buttons, and the display screen provides real-time feedback on the operating status. When the temperature exceeds the threshold or the timer ends, the control center automatically cuts off the heating power and flashes an alarm on the display screen.

[0035] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
