[0015] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0016] Referring to Figs. 1-2The utility model provides an electrodeless ultraviolet lamp, including base 1, be provided with electric push rod 2 in base 1, the telescopic portion of electric push rod 2 is connected with lampshade 3 through torsional spring, install lamp tube 4 in lampshade 3, the side surface of base 1 is provided with inclined plane 11, the side of lampshade 3 close to electric push rod 2 is provided with contact surface 33, and lampshade 3 is the hollow triangle of inside.In the production of heat-sealed film square bottom bag, due to the limitation of factory area, need through the elevator to move heat-sealed film square bottom bag from one production line to another production line to carry out packaging, therefore operating personnel installs electrodeless ultraviolet lamp in the front of production line conveyor belt elevator, when conveyor belt transports heat-sealed film square bottom bag, because the elevator transports last heat-sealed film square bottom bag to packaging production line needs certain time, the heat-sealed film square bottom bag in this time period is in the waiting state and is irradiated by two electrodeless ultraviolet lamps, and in the process of elevator ascending, operating personnel controls electric push rod 2 and slowly contracts and drives lampshade 3 and lamp tube 4 to slowly move down, when lampshade 3 contacts with inclined plane 11, lampshade 3 starts to rotate under the guidance of inclined plane 11, until the contact surface 33 of lampshade 3 and inclined plane 11 are pasted, in the process of rotating, the irradiation direction of lamp tube 4 gradually changes, from the initial oblique downward irradiation slowly changes into parallel irradiation, and the irradiation point also gradually moves from the top of heat-sealed film square bottom bag to the side of heat-sealed film square bottom bag, finally directly irradiates the side of heat-sealed film square bottom bag, thereby carries out multi-direction ultraviolet irradiation sterilization to heat-sealed film square bottom bag, when the elevator transports last heat-sealed film square bottom bag and starts to descend, in the process of elevator descending, operating personnel controls electric push rod 2 and elongates, so that lampshade 3 and lamp tube 4 slowly ascend, again carry out ultraviolet irradiation sterilization to heat-sealed film square bottom bag in the process of ascending, after leaving inclined plane 11, lampshade 3 resets through torsional spring, at this moment, conveyor belt transports heat-sealed film square bottom bag in the waiting state to the elevator and transports next heat-sealed film square bottom bag to the irradiation of electrodeless ultraviolet lamp and waits, so circulates, carries out ultraviolet irradiation sterilization to batch heat-sealed film square bottom bag.The utility model slowly lowers lampshade 3 through electric push rod 2, ensures that heat-sealed film square bottom bag is irradiated by ultraviolet for a long time and sterilized, simultaneously uses the inclined plane 11 of base 1 to guide lampshade 3, thereby makes lampshade 3 rotate to drive lamp tube 4 to move, makes the irradiation direction of ultraviolet emitted by lamp tube 4 change, makes heat-sealed film square bottom bag receive irradiation in multiple directions, improves sterilization effect.
[0017] In some embodiments, one light shield 32 is rotatably connected to each side of the lampshade 3. When the electrodeless ultraviolet lamp is used to irradiate the heat-sealed film square bottom bag, the operator can fold the light shields 32 on both sides of the lampshade 3, so that the two light shields 32 shield the two sides of the lampshade 3, reducing the irradiation range of the ultraviolet light emitted by the lamp tube 4, thereby concentrating on the heat-sealed film square bottom bag, improving the utilization rate of ultraviolet light, and increasing the sterilization intensity of ultraviolet light on the heat-sealed film square bottom bag.
[0018] In some embodiments, the lampshade 3 is provided with a chamfer 31 close to one end of the base 1. When the electric push rod 2 drives the lampshade 3 to move downward, the chamfer 31 of the lampshade 3 is in contact with the inclined surface 11 of the base 1 in advance, and the chamfer 31 can quickly make the lampshade 3 rotate under the influence of the inclined surface 11, so that the lampshade 3 is not blocked by the inclined surface 11, and the ultraviolet light emitted by the lamp 4 is always directed to the heat-sealed film square bottom bag, thereby improving the fluency of the change of the irradiation direction of the electrodeless ultraviolet lamp.
[0019] In some embodiments, the bottom surface of the base 1 is provided with a magnetic sticker 12. The base 1 can be firmly attracted to the placement plane through the magnetic sticker 12, so as to prevent the electrodeless ultraviolet lamp from being displaced or falling due to the contact of the electrodeless ultraviolet lamp by the operator or the heat-sealed film square bottom bag, prevent the sterilization of the heat-sealed film square bottom bag from being insufficient or the electrodeless ultraviolet lamp from being damaged, and improve the safety.
[0020] In some embodiments, a groove is formed on one side of the inclined surface 11 of the base 1. When the electric push rod 2 drives the lampshade 3 to move downward, the connection between the lampshade 3 and the electric push rod 2 will move downward into the groove, so that the depth of the downward movement of the lampshade 3 is increased, thereby not only increasing the ultraviolet irradiation time of the heat-sealed film square bottom bag on the conveying belt, but also being capable of irradiating different positions of the heat-sealed film square bottom bag with ultraviolet light, so as to sterilize more comprehensively.
[0021] In some embodiments, the side of the base 1 away from the inclined surface 11 is provided with an arc shape. When the operator needs to move or carry the electrodeless ultraviolet lamp, the arc-shaped side of the base 1 away from the inclined surface 11 can better enable the operator to hold the base 1, so that the operator can hold more tightly, and ensure that the electrodeless ultraviolet lamp will not fall off during the movement or carrying process, thereby avoiding the damage of the electrodeless ultraviolet lamp and prolonging the service life of the electrodeless ultraviolet lamp.
[0022] The specific embodiments are only an explanation of the present application, and are not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, as long as the modifications are within the scope of the claims of the present application.
