Detailed Description

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

Fig. 1 to 7 show a preferred embodiment of the disinfection cabinet with a pulse lamp according to the present invention. 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 tube cover 3, a first porcelain head 4 and a second porcelain head 5.

Specifically, the tube 1 is filled with a rare gas (generally, xenon), and the two ends of the tube 1 are a cathode end and an anode end, respectively.

The trigger wire 2 is wound around the outer circumference of the tube body 1, and has a lead-out end to which an external trigger lead wire 21 is connected.

The tube cover 3 is sleeved on the periphery of the tube body 1, an interlayer 31 is formed between the inner peripheral wall of the tube cover and the outer peripheral wall of the tube body 1, the trigger wire 2 is accommodated in the interlayer 31, the tube cover 3 allows pulse flash to penetrate through, and the interior of the interlayer 31 is vacuumized. In this embodiment, the tube cover 3 is made of violet-transmitting quartz glass, and the arrangement of the tube cover 3 plays two roles: on one hand, when the disinfection cabinet electrified pulse lamp tube 10 works, the risk that appliances or human bodies in the cabinet body 7 contact high voltage on the trigger wire 2 can be effectively prevented, and ozone generated by ionization of the trigger wire 2 or ozone leakage can be avoided; on the other hand, the pulsed lamp 10 generates noise due to arc discharge during two-stage discharge, and the tube cover 3 can effectively eliminate or reduce the discharge noise.

The first porcelain head 4 and the second porcelain head 5 are respectively connected to two ends of the tube cover 3 in a sealing manner, 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 first porcelain head, and the cathode end 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 is provided with two second pins 51, and the anode end 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 42 for the external trigger lead 21 to pass through is formed in the first porcelain head 4, and a guide groove 43 communicated with the through hole 42 is formed in 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 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.

The working principle of the utility model is as follows: 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 holders 6 in a contra-rotating manner respectively until, as shown in fig. 4 to 7, 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 holders 6, at this time, the first pin 41 and the second pin 51 are in an unlocked state, and the pulse lamp 10 is moved forward to enable the first pin 41 and the second pin 51 to be separated from the slots 61, so that the clockwise rotation is required to be about 90 °, as shown in fig. 2 and 3, after the rotation, the first pin 41 and the second pin 51 are in a locked state, and the forward movement of the pulse lamp 10 cannot enable the first pin 41 and the second pin 51 to be separated from the slots 61. 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 connected with the trigger circuit to complete the installation of the pulse lamp 10.
