Description

Technical Field

[0001] The utility model relates to the field of ultraviolet sterilization lamps, in particular to a pulse ultraviolet sterilization lamp. Background Art

[0002] Ultraviolet (UV) germicidal lamps use ultraviolet radiation to kill bacteria, viruses, and other microorganisms. Ultraviolet radiation is a short-wavelength, high-energy electromagnetic radiation. When irradiated by UV rays, it destroys the nucleic acids of microorganisms, rendering them unable to reproduce and survive. UV germicidal lamps are widely used in the medical, food, water treatment, and air purification industries.

[0003] Pulsed ultraviolet germicidal lamps are a new type of sterilization equipment developed based on traditional ultraviolet germicidal lamps. Compared with traditional ultraviolet germicidal lamps, pulsed ultraviolet germicidal lamps have higher sterilization efficiency. Pulsed ultraviolet germicidal lamps can release high-intensity ultraviolet pulses in a short period of time. Their radiation intensity is several times or even dozens of times higher than that of traditional ultraviolet germicidal lamps. This high-intensity ultraviolet pulse can kill bacteria, viruses and other microorganisms more quickly and effectively, thereby improving sterilization efficiency.

[0004] The current passed through the existing pulsed ultraviolet germicidal lamp is relatively stable, so the intensity of the ultraviolet light emitted by the rare gas excited by the current is also relatively fixed. However, this situation makes it difficult to adjust the intensity of the ultraviolet light emitted by the pulsed ultraviolet germicidal lamp according to environmental requirements. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a pulsed ultraviolet germicidal lamp to solve the technical problem that the traditional pulsed ultraviolet germicidal lamp is difficult to adjust the intensity of the ultraviolet light projected onto the outside of the lamp.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a pulsed ultraviolet sterilization lamp tube, comprising a lamp tube main body, a quartz glass tube installed inside the lamp tube main body, a first electrode wire connected to one side of the quartz glass tube, and the first electrode wire is connected to the positive pole of the power supply, a first electrode is installed at the end of the first electrode wire, a second electrode wire is provided at one end of the quartz glass tube, and the second electrode wire is connected to the negative pole of the power supply, a second electrode is installed at the end of the second electrode wire, a discharge cavity is provided inside the quartz glass tube, the interior of the discharge cavity is filled with a rare gas, and the outer wall of the quartz glass tube is sheathed with an electric heating ring.

[0007] By adopting the above technical solution, the technical problem that the traditional pulsed ultraviolet sterilization lamp is difficult to adjust the intensity of the ultraviolet light projected onto the outside of the lamp is solved. The power supply outputs current to the first electrode wire, and the first electrode wire guides the current to the first electrode. Since there is a certain concentration of rare gas between the first electrode and the second electrode, the rare gas acts as a conductor, so that a high-voltage arc is generated between the first electrode and the second electrode. The high-voltage arc excites the rare gas to emit ultraviolet light. The current is transmitted to the electric heating coil through the adjustment wire, and the electric heating coil converts electrical energy into thermal energy. The electric heating coil transmits the converted heat energy to the quartz glass tube. The temperature of the quartz glass tube rises, which increases the quartz glass tube's ability to absorb ultraviolet light, thereby reducing the intensity of the ultraviolet light inside the discharge cavity projected to the outside of the lamp body.

[0008] The utility model is further configured such that an outer wall of the electric heating coil is connected to an adjusting wire, and the adjusting wire is connected to a power source capable of regulating current.

[0009] By adopting the above technical solution, the current-controllable power supply can output currents of different values, and the regulating wires can conduct the current to the electric heating ring, causing the electric heating ring to emit different degrees of heat, thereby changing the surface temperature of the quartz glass tube.

[0010] The present invention is further configured such that a vacuum cavity is provided inside the lamp tube body, and the vacuum cavity is difficult to conduct matter and energy.

[0011] By adopting the above technical solution, the heat emitted by the electric heating coil causes the overall temperature of the quartz glass tube to rise. A vacuum chamber is provided inside the lamp tube body, so that the heat on the surface of the quartz glass tube will not be transferred to the lamp tube body, preventing workers from being burned by the heat on the quartz glass tube when touching the lamp tube body.

[0012] The present invention is further configured such that two groups of first reinforcement blocks are provided on the inner wall of the lamp tube body, and the first reinforcement blocks are located at both ends of the lamp tube body.

[0013] By adopting the above technical solution, two groups of first reinforcement blocks are respectively arranged at both ends of the inner wall of the lamp tube body, and the first reinforcement blocks are arranged in an arc shape, thereby strengthening the connection between the lamp tube body and the first electrode wire and the second electrode wire.

[0014] The present invention is further configured such that a protective sleeve is installed on the outer wall of the lamp tube body, and the protective sleeve is made of rubber.

[0015] By adopting the above technical solution, the protective sleeves are installed at both ends of the outer wall of the lamp tube body, and the protective sleeves are made of rubber material, so that the protective sleeves can provide a certain degree of protection for the lamp tube body.

[0016] The utility model is further configured such that an insulating sleeve is fixed on one side of the protective sleeve, and the insulating sleeve is configured to be conical.

[0017] By adopting the above technical solution, the insulating sleeve is made of silicone material. The insulating sleeve made of silicone material has good flexibility and elasticity. In addition to preventing leakage at the connection between the first electrode wire and the lamp tube body, the insulating sleeve can also reduce the wear between the first electrode wire and the lamp tube body.

[0018] The present invention is further configured such that two groups of second reinforcement blocks are provided on the inner wall of the quartz glass tube, and the second reinforcement blocks are located at both ends of the quartz glass tube.

[0019] By adopting the above technical solution, two groups of second reinforcement blocks are respectively arranged at both ends of the inner wall of the quartz glass tube, and the second reinforcement blocks are arranged in an arc shape, so that the connection between the quartz glass tube and the first electrode wire and the second electrode wire is prevented from the rare gas inside the discharge chamber from penetrating the quartz glass tube.

[0020] The present invention is further configured such that the rare gas is xenon, which has the characteristics of high energy intensity and low ionization potential.

[0021] By adopting the above technical solution, xenon gas can release high-energy ultraviolet rays during pulse discharge, thereby increasing the efficiency of ultraviolet sterilization of the device. In addition, the ionization potential of xenon gas is low, and the voltage drop near the first electrode during discharge is small, so that the voltage stress on the first electrode is small, which can reduce the loss and aging of the first electrode, thereby extending the service life of the lamp tube body.

[0022] In summary, the present invention has the following beneficial effects:

[0023] The utility model solves the technical problem of the difficulty in adjusting the intensity of ultraviolet light projected onto the outside of the lamp tube in conventional pulsed ultraviolet sterilization lamps by providing a lamp tube body, an adjustment wire, an electric heating coil, a first electrode, a second electrode, a quartz glass tube, and a rare gas. The power supply outputs current to the first electrode wire, and the first electrode wire guides the current to the first electrode. Since there is a certain concentration of rare gas between the first electrode and the second electrode, the rare gas acts as a conductor, so that a high-voltage arc is generated between the first electrode and the second electrode. The high-voltage arc excites the rare gas to emit ultraviolet light. The current is conducted to the electric heating coil through the adjustment wire, and the electric heating coil converts electrical energy into heat energy. The electric heating coil conducts the converted heat energy to the quartz glass tube. The temperature of the quartz glass tube rises, thereby increasing the ultraviolet light absorption property of the quartz glass tube, thereby reducing the intensity of the ultraviolet light projected from the discharge cavity to the outside of the lamp tube body.

[0024] The utility model is provided with a lamp tube body, a vacuum chamber, a protective sleeve and an insulating sleeve. When current is passed through the regulating wire, the electric heating coil emits heat, so that the overall temperature of the quartz glass tube rises. The vacuum chamber is provided inside the lamp tube body, so that the heat on the surface of the quartz glass tube will not be conducted to the lamp tube body, thereby preventing workers from being burned by the heat on the quartz glass tube when touching the lamp tube body.

The high-voltage arc excites the rare gas 7 to emit ultraviolet light. The current is conducted to the electric heating ring 301 through the regulating wire 3. The electric heating ring 301 converts electrical energy into thermal energy. The electric heating ring 301 conducts the converted thermal energy to the quartz glass tube 6. The temperature of the quartz glass tube 6 rises, which increases the quartz glass tube 6's ability to absorb ultraviolet light, thereby reducing the intensity of the ultraviolet light inside the discharge cavity 602 projected to the outside of the lamp body 1.

The power supply with adjustable current can output currents of different values. The adjusting wire 3 conducts the current to the electric heating ring 301, causing the electric heating ring 301 to emit different degrees of heat, thereby changing the surface temperature of the quartz glass tube 6.

The electric heating coil 301 converts electrical energy into thermal energy, and the electric heating coil 301 conducts the converted thermal energy to the quartz glass tube 6. The temperature of the quartz glass tube 6 rises, which increases the quartz glass tube 6's ability to absorb ultraviolet light. Then the power supply outputs current to the first electrode wire 4, and the first electrode wire 4 guides the current to the first electrode 401. Since there is a certain concentration of rare gas 7 between the first electrode 401 and the second electrode 501, the rare gas 7 acts as a conductor, so that a high-voltage arc is generated between the first electrode wire 4 and the second electrode wire 5.
