Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

Example 1:

referring to fig. 1 to 6, there is shown a first preferred embodiment of the disinfection cabinet of the present invention using a pulse lamp. The disinfection cabinet comprises a cabinet body 7, a pulse lamp tube 10 and a lamp holder 6. As shown in fig. 1, two ends of the pulse lamp 10 are mounted on the inner side wall of the cabinet 7 through two lamp holders 6.

The pulse lamp tube 10 comprises a tube body 1, a trigger wire 2, a first porcelain head 4 and a second porcelain head 5.

Specifically, as shown in fig. 6, the pipe body 1 includes an inner pipe 11 and an outer pipe 12 surrounding the inner pipe 11, the inner pipe 11 has an inner cavity 111 therein, the inner cavity 111 is filled with an inert gas (generally xenon), the inner cavity 111 includes a cathode region, an intermediate region and an anode region arranged in sequence along the axial direction, the cathode region is provided with a cathode 1111, and the anode region is provided with an anode 1112; a barrier layer 121 is formed between the inner circumferential wall of the outer tube 12 and the outer circumferential wall of the inner tube 11, and the barrier layer 121 is evacuated or filled with an inert gas (e.g., argon, krypton, xenon, etc.). Generally, the barrier 121 is first evacuated and then flushed with an inert gas.

In this embodiment, the spacer 121 only surrounds the middle region, i.e. the outer tube 12 only surrounds the inner tube 11 outside the middle region. The reason is that: when the tube body 1 is made of quartz glass, the inner tube 11 needs to be formed outside the cathode and the anode, and then the outer tube 12 needs to be formed outside the inner tube 11, but the melting point of the quartz glass is about 130 ℃, if the coverage area of the interlayer 121 is too large, if the whole inner tube 11 is wrapped, the risk of burning and melting the cathode 1111 and the anode 1112 exists, so the interlayer 121 only wraps the middle area, the production manufacturability is better, but the noise reduction effect is slightly reduced.

The trigger wire 2 is located in the above-mentioned partition 121 and wound around the outer peripheral wall of the inner tube 11, and has a lead-out end to which an outer trigger wire 21 is connected.

The first porcelain head 4 and the second porcelain head 5 are respectively connected to two ends of the tube body 1, the first porcelain head 4 is installed at the first end of the tube body 1, two first pins 41 are arranged at the end part of the tube body 1, and the cathode 1111 of the tube body 1 is electrically connected with one first pin 41 through a lead; the second porcelain head 5 is installed at the second end of the tube body 1, and the end part of the second porcelain head has two second pins 51, and the anode 1112 of the tube body 1 is electrically connected with one of the second pins 51 through a lead. In this way, the pulse tube 10 can be adapted thereto without the need for modifying an existing lamp holder.

In addition, a through hole (not shown) for the external trigger lead 21 to pass through is formed through the first porcelain head 4, and a guide groove 43 communicated with the through hole 42 is formed on the outer peripheral wall of the first porcelain head 4 along the circumferential direction. In this embodiment, the guide groove 43 is arc-shaped, and the central angle is 90 °.

The interior of the tube body 1 of the pulse lamp tube 10 can generate pulse flash with the wavelength of 200-1100 nm, and the interior of the cabinet body is efficiently disinfected through the tube body 1. 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 per cm²When the peak power of the area reaches more than 1000W, the microorganisms are heated>At 100 ℃, because the flash irradiation time is extremely short, microorganisms can not be cooled normally, 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.

One end of the lamp holder 6 is provided with a slot 61 for the first pin 41 or the second pin 51 to be inserted into, the end of the first pin 41 or the second pin 51 is in contact with the end wall of the slot 61 to realize electrical connection, and the front side wall of the lamp holder 6 is provided with a notch 62 communicated with the slot 61 for the first pin 41 or the second pin 51 to pass through and enter the slot 61. The socket 61 is substantially cylindrical, and the two first pins 41 or the two second pins 51 can rotate around the axis of the socket 61 in the socket 61 so as to enable the first pins 41 or the second pins 51 to be in a locking state or an unlocking state.

The inner wall of the cabinet body 7 facing the tube body 1 is provided with a reflecting cover 71 for reflecting the pulse flash generated by the pulse lamp tube 10.

Example 2:

fig. 7 shows a second preferred embodiment of the disinfection cabinet of the present invention, which is applied with a pulse lamp. The difference from example 1 is that:

in this embodiment, the separator 121 surrounds the cathode, intermediate and anode regions, i.e. the outer tube 12 surrounds the entire outer side of the inner tube 11. Thus, the pipe body 1 has a better noise reduction effect, but has a poor production manufacturability.

Taking embodiment 1 as an example, the working principle of this embodiment is as follows:

(1) during installation, the first pin 41 and the second pin 51 of the pulse lamp 10 only need to be inserted into the notches 62 of the two lamp sockets 6 in a contra-rotating manner until, as shown in fig. 4 and 5, the two first pins 41 and the second pin 51 of the pulse lamp 10 are both inserted into the slots 61 of the corresponding lamp sockets 6, at this time, the first pin 41 and the second pin 51 are in an unlocked state, and the first pin 41 and the second pin 51 can be separated from the slots 61 by moving the pulse lamp 10 forward, so that the first pin 41 and the second pin 51 need to rotate forward by about 90 °, as shown in fig. 2 and 3, after rotation, the first pin 41 and the second pin 51 are in a locked state, and the first pin 41 and the second pin 51 cannot be separated from the slots 61 by moving the pulse lamp 10 forward. In addition, the end parts of the two first pins 41 and the second pins 51 are in contact with the end walls of the corresponding slots 61 to realize electric connection, and because the two pins are electrified, the cathode end and the anode end of the tube body 1 can be ensured to be connected to any pin to realize circuit conduction, and error-proof design is not needed when the cathode end and the anode end of the tube body 1 are threaded, so that the assembly efficiency of the lamp tube is improved; meanwhile, the external trigger lead 21 is wound down from the guide groove 43 and is connected with the trigger circuit, so that the installation of the pulse lamp tube 10 can be completed;

(2) when the pulse lamp tube 10 is used, when the pulse lamp tube 10 flashes, gas spark discharge is caused, and when the capacitor energy is released, the rare gas in the inner cavity 111 rapidly expands to form gas shock waves and generate noise; the high voltage exists on the trigger wire 2, the air can be ionized after the trigger wire contacts with the air, ozone is generated, and the risks of ozone odor, ozone residue and high-voltage false touch exist;

the propagation of sound in the air is found, firstly, the propagation of sound can be isolated in a vacuum environment, secondly, the molecular weight (Kr, Xe) of rare gas is higher than that of air, the gas constant R is small, and the sound isolation effect is good; through locating trigger wire 2 in interlayer 112, can effectively protect sterilizer circular telegram pulse lamp tube 10 during operation, utensil or human body contact the risk of high voltage on the trigger wire 2 in the cabinet body 7, can avoid trigger wire 2 ionization to produce ozone or ozone to leak simultaneously.
