Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 5, a preferred embodiment of the layered disinfection cabinet of the present invention is shown. The layered disinfection cabinet comprises a cabinet body 1, a partition board 2, a lamp tube 3, a first lamp holder 4, a second lamp holder 5 and a filter cover 6.

The cabinet body 1 comprises a shell 11 and an inner container 12 arranged in the shell 11, and a disinfection cavity 121 is arranged in the inner container 12.

The partition plate 2 is arranged substantially horizontally in the middle of the sterilization chamber 121 and divides the sterilization chamber 121 into a first chamber 1211 located above and a second chamber 1212 located below. The rear part of the partition plate 2 is provided with a mounting opening 21, the partition plate 2 is hollow and is internally provided with a heating element 22 which can dry the first chamber 1211 and the second chamber 1212 at the same time, and the cost of parts is saved. In this embodiment, the heating member 22 includes at least two U-shaped heating pipes connected end to end in sequence to serve as a planar heating source, and the partition plate 2 is made of a heat conductive material.

The lamp tube 3 is arranged substantially vertically and is inserted into the mounting opening 21, and two ends of the lamp tube 3 are respectively mounted on the rear side wall of the inner container 12 through the first lamp holder 4 and the second lamp holder 5. Specifically, the lamp tube 3 includes a tube body 31 filled with xenon gas therein and a trigger wire 32 wound around an outer circumferential wall of the tube body 31, wherein the tube body 31 is made of a fully transparent quartz glass.

The lamp 3 can generate a pulse flash with a wavelength of 200-1100 nm, and simultaneously acts on the first and

second chambers

1211 and 1212 to efficiently sterilize them. The action mechanism of the pulse flash sterilization is the synergistic action of all wave bands in a spectral range, and is mainly embodied in three aspects:

(1) photochemical reaction in ultraviolet band: when the microorganism is irradiated by ultraviolet light in the pulsed intense light spectrum, thymine and cytosine in nucleic acid substances (DNA and RNA) generate photochemical reaction to generate dimers, so that the nucleic acid substances of the microorganism are damaged);

(2) flash heating effect: when the peak power per cm2 area reaches more than 1000W, the microorganism is heated to more than 100 ℃, and the microorganism can not be cooled normally due to extremely short flash irradiation time, so that cell walls are broken and melted to die;

(3) pulse effect: the penetration of the intense pulsed light and the transient high energy mechanical impact damage the cell walls and other cellular components, resulting in bacterial death.

In addition, the spectrum range of the pulse flash covers ultraviolet, visible light and infrared light parts, the ultraviolet wave band and ozone generated by 185nm ultraviolet, the pulse flash has strong oxidizability, and plastic tableware is irradiated by the ultraviolet for a long time, so that the risk of aging and powdering exists.

The first lamp holder 4 comprises a fixed base 41, a movable base 42 and an elastic member 43. Specifically, the end of the fixing seat 41 is provided with a mounting groove 411, the inner wall of the mounting groove 411 is provided with at least two first protruding edges 412 arranged at intervals along the circumferential direction, and a gap 413 is formed between every two adjacent first protruding edges 412; the first end of the movable seat 42 is accommodated in the installation groove 411, and the end surface is provided with an annular groove 423, the end surface of the second end is provided with a first socket 421 for the first end of the pipe body 31 to be inserted, the outer peripheral wall of the movable seat 42 is provided with a second convex edge 422 which is convexly arranged outwards and corresponds to the first convex edge 412 one by one, the second convex edge 422 can enter the installation groove 411 through a gap 413, and is limited between the bottom wall of the installation groove 411 and the first convex edge 412 after rotating; the elastic member 43 is a compression spring, is located in the mounting groove 411, and is partially accommodated in the annular groove 423, two ends of the elastic member 43 respectively abut against the fixed seat 41 and the movable seat 42, so that the second convex edge 422 of the movable seat 42 always has a tendency of being close to the first convex edge 412 of the fixed seat 41.

The end of the second socket 5 is opened with a second socket 51 into which the second end of the tube 31 is inserted.

The filter cover 6 is tubular and is sleeved on the periphery of the tube body 31, an interlayer 61 is formed between the inner peripheral wall of the filter cover 6 and the outer peripheral wall of the tube body 31, the trigger wire 32 is positioned in the interlayer 61, and the interior of the interlayer 61 is vacuumized; an annular protrusion 64 is protruded along the circumferential direction on the outer circumferential wall of the filter cover 6, and the annular protrusion 64 is limited between the top wall and the bottom wall of the partition plate 2. In this embodiment, the filter mask 6 is provided to perform three functions: on one hand, the risk that an appliance or a human body in the disinfection cavity 11 contacts a high voltage on the trigger wire 22 when the electrified lamp tube 3 of the disinfection cabinet works can be effectively prevented; secondly, arc discharge generates noise when the lamp tube 3 discharges in two stages, and the filter cover 6 can effectively eliminate or reduce the discharge noise; third, the filter mask 6 can filter the light of a specific wavelength band, so as to eliminate the adverse effect of the light of the wavelength band in some application scenarios.

In this embodiment, the filter cover 6 includes a first filter portion 62 located above the separation plate 2 and a second filter portion 63 located below the separation plate 2, and the wall surfaces of the first filter portion 62 and the second filter portion 63 can filter light rays with different wavelengths respectively. Because the first optical filter part 62 is accommodated in the first cavity 1211, and the second optical filter part 63 is accommodated in the second cavity 1212, the pulse flash formed by the lamp tube 3 is respectively emitted into the first cavity 1211 and the second cavity 1212 after being filtered by the first optical filter part 62 and the second optical filter part 63, so that the wave bands of the pulse flash finally acting in the two cavities are different, different disinfection modes are realized, and the disinfection requirements of different tableware are met.

The working principle of the utility model is as follows:

(1) during installation, the first end of the tube body 31 is inserted into the first insertion opening 421 of the movable seat 42, and pressure is applied to the movable seat 42 to move the movable seat 42 close to the fixed seat 41, in the process, the elastic member 43 is compressed, the second end of the tube body 31 is inserted into the second insertion opening 51 of the second lamp holder 5, and finally the tube body 31 is released, the movable seat 42 moves away from the fixed seat 41 under the elastic force of the elastic member 43 until the second protruding edge 422 of the movable seat 42 abuts against the first protruding edge 412 of the fixed seat 41;

(2) during operation, the pulse flash formed by the lamp 3 is filtered by the first and second light-filtering

portions

62 and 63 respectively (for example, the first light-filtering portion 62 filters out the ultraviolet band, and the second light-filtering portion 63 is completely transparent) and then emitted into the first and

second chambers

1211 and 1212, so that the pulse flash finally applied to the two chambers has different bands, thereby realizing different disinfection modes and meeting the disinfection requirements of different dishware.
