Currently, the application of power batteries is more widespread from the development of market situation. The power battery is not only applied to energy storage power supply systems such as hydraulic power, firepower, wind power and solar power stations, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric automobiles, and the like, and a plurality of fields such as military equipment, aerospace, and the like. With the continuous expansion of the application field of the power battery, the market demand of the power battery is also continuously expanding.

In the manufacturing process of the battery, the coated positive plate needs to be dried. The positive electrode plate is generally dried by using a drying device, and the drying effect of the infrared radiation type drying device is optimal. However, the surface temperature of the infrared lamp tube is higher, and the coating solution of the positive plate has inflammable and explosive characteristics, and after the coating solution volatilizes, if the coating solution contacts the infrared lamp tube with higher temperature, the coating solution especially permeates into the lamp shade of the infrared lamp tube, the accident of burning or explosion can occur.

In order to solve the problem of the existing drying device that the lamp tube has inflammable and explosive safety, it can be noted that the main reason is that inflammable and explosive gas permeates into the lampshade of the infrared lamp tube. Therefore, the infrared lamp tube can be solved by preventing inflammable and explosive gas from penetrating into the lampshade of the infrared lamp tube. For example, an air inlet and an air outlet may be provided on both sides of the lamp shade of the lamp tube, air is taken in through the air inlet, and air is discharged through the air outlet. When the lamp tube works, the inside of the lamp shade starts to enter air and exhaust, and at the moment, the air pressure inside the lamp shade is higher than the air pressure outside the lamp shade, so that the outside inflammable and explosive air can not enter the lamp shade, combustion or explosion can not be generated, and the safety performance is improved. And the flow of gas can also dispel the heat to the infrared lamp body in the lamp shade, if use cooling gas, the effect is more, has further strengthened the security of fluorescent tube.

Referring to fig. 1 to 3, fig. 1 is a semi-transparent structural diagram of a lamp cover according to one or more embodiments, fig. 2 is a left-transparent structural diagram of a lamp cover according to one or more embodiments, and fig. 3 is a right-transparent structural diagram of a lamp cover according to one or more embodiments. The globe 10 includes a cover 11, a first end 12, and a second end 13. Openings are formed on opposite sides of the cover 11, a first end 12 is connected to one side opening of the cover 11, and a second end 13 is connected to the other side opening of the cover 11. An air inlet 121 is formed in the first end 12 for connection to an external air intake conduit. An air outlet 131 is formed in the second end 13 for connection to an external air outlet duct. The first end 12, the cover 11 and the second end 13 form a receiving space. The air inlet 121 and the air outlet 131 are communicated with the accommodating space. When the external air inlet pipeline is used for air inlet of the lampshade 10, the air pressure of the accommodating space is higher than the air pressure of the outside of the lampshade 10.

The cover 11 is a main structure of the lamp housing 10. The cover 11 may have a cylindrical, semi-cylindrical or other structure, and has a space formed therein with two openings at both sides for accommodating the lamp body or the like. The first end 12 and the second end 13 are connected to opposite sides of the cover 11, and are members of the lamp housing 10 for connecting an external air inlet pipe and an external air outlet pipe. The first end 12 and the second end 13 are used for closing openings on two sides of the internal space of the cover 11, so that a containing space is formed by matching with the cover 11, and components such as an infrared lamp body can be arranged in the containing space. The first end 12, the second end 13 and the cover 11 may be detachably connected, so as to facilitate maintenance of the components inside the lampshade 10. The first end 12 and the second end 13 may be connected to the cover 11 in a non-detachable manner, and now the cover 11 is provided with internal components, and then the first end 12 and the second end 13 are connected to the cover 11 by welding or bonding. The connecting mode has the advantages of high sealing performance and high connecting stability. The cover 11 may be made of a light-transmitting or semi-transmitting material, or may be made of a material capable of passing infrared rays, so that infrared rays or infrared radiation emitted from the internal infrared lamp can be emitted through the cover 11. The external air inlet pipeline can be connected with a high-pressure fan so as to ensure that the air pressure in the accommodating space is higher than the air pressure outside the lampshade 10 when the external air inlet pipeline is used for air inlet to the lampshade 10.

In this way, the gas can flow in the cover 11 of the lamp cover 10 to radiate heat to the infrared lamp body arranged in the cover 11 of the lamp cover 10, and the gas pressure inside the lamp cover 10 is higher than the gas pressure outside the lamp cover 10, so that the gas possibly having inflammable and explosive properties outside can be prevented from penetrating into the lamp cover 10, thereby improving the safety performance.

In some embodiments, the air equalizing plate 14 is connected to the inner wall of the cover 11, and an air equalizing channel is formed between the air equalizing plate 14 and the cover 11, and/or the air equalizing plate 14 itself is formed with an air equalizing channel.

When the air equalizing channel is formed between the air equalizing plate 14 and the cover 11, the air equalizing plate 14 is connected with the cover 11 to form a channel structure. When the air equalizing plate 14 forms an air equalizing channel, the air equalizing plate 14 is of a pipeline structure and is connected with the inside of the cover body 11. The air equalizing plate 14 may be detachably connected to the cover 11, for example, by a snap fit or a slide way. The air equalizing plate 14 may be connected to the cover 11 in a non-detachable manner, for example, by welding, adhering, or the like. There may be or may be louvers 14 integrally formed with the housing 11. The effect of the air equalizing plate 14 is to uniformly flow out the air in the air equalizing channel, so that more than half of the air in the air equalizing channel flows into the accommodating space or the air uniformly flows in the accommodating space.

The air equalizing plates 14 can form an air equalizing channel, so that the temperature of each part in the lampshade 10 is kept consistent as much as possible, and the temperature of the outer surface of the lampshade 10 is kept consistent as much as possible.

With further reference to fig. 4, fig. 4 is a schematic elevational view of a damper according to one or more embodiments. In some embodiments, the air equalizing plate 14 includes a connecting portion 141 and an air equalizing portion 142, the connecting portion 141 connects the cover 11 and the air equalizing portion 142, the air equalizing portion 142 cooperates with the cover 11 and/or the connecting portion 141 to form an air equalizing channel, and the air equalizing portion 142 is provided with air equalizing holes 143.

The wind equalizing portion 142 is used for realizing a wind equalizing effect, and through the arrangement of the wind equalizing holes 143, airflow in the wind equalizing channel orderly flows into the accommodating space outside the wind equalizing channel. Since the air equalizing holes 143 do not need to be formed in the cover 11, the cover 11 and the air equalizing portion 142 are connected by the connecting portion 141, and the air equalizing holes 143 may be formed in the air equalizing portion 142. The air equalizing hole 143 may be a circular through hole, or may change the shape and structure of the hole according to the requirement, for example, the opening direction of the hole may be perpendicular to the air equalizing portion 142, or may be inclined relative to the air equalizing portion 142 along the direction from the air inlet 121 to the air outlet 131. In some embodiments, the connection portions 141 are disposed on both sides of the wind equalizing portion 142, the connection portions 141 are connected to the inner wall of the housing 11, and the wind equalizing portion 142 is disposed at a distance from the inner wall of the housing 11. By the arrangement, a gap is formed between the air equalizing part 142 and the cover 11, and air in the accommodating space can enter the air equalizing channel through the gap and then be blown out by the air equalizing holes 143.

The arrangement mode can enable the air equalizing channel to have a certain space, and is convenient for the arrangement of the air equalizing channel. The arrangement of the air equalizing holes 143 can be that the air in the air equalizing channels flows out of the air equalizing channels sequentially through the air equalizing holes 143, so that the inside of the lamp shade 10 is cooled sequentially, and the temperature consistency of the outer surface of the lamp shade 10 is improved.

In some embodiments, the size of the air equalization holes 143 is gradually increased or the density of the air equalization holes 143 is gradually increased along the direction from the first end 12 to the second end 13.

The direction along the first end 12 to the second end 13, i.e. the direction from the air inlet to the air outlet, is also the length direction of the lampshade 10 and the lampshade body 11. Air enters the accommodating space through the external air inlet pipeline, one part of the air enters the air equalizing channel, and the other part of the air directly circulates in the accommodating space. Therefore, the temperature near the first end 12 is directly reduced by the air flowing in the accommodating space. The size of the air equalizing holes 143 gradually becomes larger, so that more air with relatively low temperature in the air equalizing channel can be obtained near the air outlet, the cooling effect near the air outlet is enhanced, and the overall temperature consistency inside the lampshade 10 is realized. In addition, in some embodiments, the air equalizing channel may be gradually configured from the first end 12 to the second end 13, so that the air in the air equalizing channel flows out through the air equalizing hole 143.

The mode enables cooling gas entering from the air inlet to flow out in the air homogenizing channel along the direction from the air inlet to the air outlet, so that a better cooling effect can be obtained at a part, which is relatively poor in conventional cooling effect and is close to the air outlet, and the temperature consistency is realized as much as possible.

In some embodiments, the air distribution plate 14 is provided with at least two air distribution channels so as to form at least two air distribution channels, and the distances from the at least two air distribution channels to the central axis inside the cover 11 are equal.

The arrangement of the plurality of air distribution plates 14 represents a plurality of air distribution channels. The more air equalizing channels, the more cool air can be stored. By arranging the plurality of air equalizing plates 14, a plurality of air equalizing channels can be realized, and enough cold air can be obtained from the part close to the second end part 13, so that a good temperature equalizing effect is realized.

The setting mode can further improve the air equalizing effect, so that the temperature consistency is improved.

With further reference to fig. 5, fig. 5 is a schematic diagram of an exploded structure of a lamp in accordance with one or more embodiments. In some embodiments, the cover 11 includes a first cover 111 and a second cover 112, the second cover 112 being located outside of the first cover 111, the first cover 111 and the second cover 112 being connected to the first end 12 and the second end 13.

The first cover 111 is mated with the second cover 112 such that the cover 11 is a double-layered cover 11. The first cover 111 and the second cover 112 may be made of the same material, such as quartz. The first cover 111 and the second cover 112 may be attached to each other or may be provided at intervals. The first cover 111 and the second cover 112 have the same shape and only have different sizes. For example, the first cover 111 and the second cover 112 are both cylindrical, the diameter of the first cover 111 is smaller than that of the second cover 112, and the length of the first cover 111 is equal to that of the second cover 112.

The double-layer cover 11 can make the tightness of the lampshade 10 stronger and the compression resistance stronger.

In some embodiments, a first buffer is disposed between the first cover 111 and the second cover 112.

The first buffer member is a flexible structure or an elastic structure, and is used for buffering between the first cover 111 and the second cover 112. The first cushioning member may be foam, such as high temperature cushioning foam. The first buffer may completely fill the space between the first cover 111 and the second cover 112.

When the first cover 111 and/or the second cover 112 are/is expanded with heat and contracted with cold, the first buffer member can buffer the first cover 111 and the second cover 112 to avoid damage caused by rigid collision due to expansion with heat and contraction with cold.

In some embodiments, the cover 11 further includes a liner housing 114, and the liner housing 114 is disposed inside the first cover 111.

The liner housing 114 may have a structural strength greater than that of the first and second covers 111 and 112. The liner housing 114 is connected to the air equalizing plate 14 to form an air equalizing passage. The liner case 114 is the innermost member of the cover 11, and may have the same shape and size as the first cover 111. For example, the first cover 111 and the liner housing 114 are both cylindrical, the diameter of the liner housing 114 is smaller than that of the first cover 111, and the length of the liner housing 114 is equal to that of the first cover 111.

The provision of the inner shell 114 may enhance the sealability and crush resistance of the globe 10.

In some embodiments, a second buffer 113 is disposed between the liner housing 114 and the first cover 111.

The second buffer member 113 is a flexible structure or an elastic structure, and is used for buffering between the first cover 111 and the liner housing 114. The second buffer 113 may be foam, for example, high temperature buffer foam. The first buffer may completely fill the space between the first cover 111 and the liner case 114.

When the first cover 111 and/or the liner shell 114 are/is expanded with heat and contracted with cold, the first buffer member can buffer the first cover 111 and the liner shell 114 to a certain extent, so that the first cover 111 and the liner shell 114 are not damaged due to rigid collision caused by expansion with heat and contraction with cold.

In some embodiments, the housing 11 further includes an outer housing 115, the outer housing 115 being disposed outside of the second housing 112.

The outer cover 115 is disposed on a surface of the second cover 112 away from the first cover 111, for protecting the second cover 112 and the inner parts. The outer housing 115 may have a structural strength higher than that of the second housing 112 and the first housing 111.

The outer cover 115 protects the second cover 112 and the first cover 111, and prevents the second cover 112 and even the first cover 111 from being damaged due to the impact of external components. The shape of the outer cover 115 may be the same as the second cover 112, and only the size may be different. For example, the outer housing 115 and the second housing 112 are both cylindrical, the diameter of the outer housing 115 is larger than that of the second housing 112, and the length of the outer housing 115 is equal to that of the second housing 112.

In some embodiments, the lamp housing 10 further includes a mount 15, the mount 15 being coupled to an outer wall of the housing body 11 for securing the lamp housing 10 to an external component.

The mount 15 is a member to which the globe 10 is connected to the outside. Mount 15 may be coupled to housing 115. Since the main body structure of the housing 11 is generally cylindrical, that is, the outer housing 115, the second housing 112, the first housing 111, and the like are generally cylindrical, connection with external components is not easy, and thus the mount 15 is provided, and connection of the lamp housing 10 with external components is achieved by the mount 15. The mounting member 15 may be of a ring-shaped structure, a square-shaped structure, a sheet-shaped structure, a plate-shaped structure, or the like. The mount 15 may be detachably connected or non-detachably connected to the outer wall of the housing 11. For example, the mount 15 may be coupled to the housing 115 by being snapped, glued, welded, or integrally formed.

The mount 15 enables the lamp housing 10 to be connected with external parts in a simple manner without damaging the internal structure of the lamp housing 10.
