Description

Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology, and in particular to a lamp housing capable of generating eddy currents. Background Technology

[0002] Diving chambers and mining environments pose a high risk of oxygen deficiency.

[0003] In the mine environment, especially in areas such as goaf and return air corners, oxygen concentration is prone to decrease due to air leakage or unreasonable ventilation system design.

[0004] The diving chamber environment is a closed space. In a closed space, a failure of the oxygen supply system or high-density oxygen consumption may lead to a sudden lack of oxygen, causing the risk of suffocation.

[0005] Working in a mine requires both lighting and oxygen supply. Traditional lighting and oxygen supply equipment require separate spaces, which affects work efficiency and can also lead to overcrowding, hindering emergency evacuation and increasing the risk of accidents.

[0006] Therefore, how to achieve synergy between effective lighting and rapid oxygen supply while reducing the space occupied by the equipment has become a pressing technical challenge. Utility Model Content

[0007] The purpose of this invention is to solve one of the above-mentioned defects and provide a lamp housing that can generate eddy currents.

[0008] The objective of this utility model is achieved through the following means:

[0009] A lamp housing capable of generating eddies includes a cylindrical housing with a downward opening through which light shines downward. A fan is provided on the side wall of the housing to create a negative pressure inside the housing. Air below the housing is drawn into the housing through the opening under the action of the negative pressure inside the housing and is discharged from the side wall by the fan. The fan blows the air toward an oxygen plate on the outside of the housing.

[0010] As a preferred embodiment, the number of fans is two, and the two fans are arranged radially on the side wall of the housing.

[0011] As a preferred embodiment, the two fans are arranged opposite each other.

[0012] As a preferred embodiment, the sidewall is provided with a number of vents for the exchange of air between the inside and outside of the housing.

[0013] As a preferred embodiment, the inner side of the sidewall is provided with a plurality of spiral guide plates spiraling upward in a clockwise / counterclockwise direction. Two adjacent spiral guide plates are equidistantly arranged, and a plurality of air holes are arranged along the spiral extension direction of the spiral guide plates. The spiral guide plates separate adjacent air holes in the vertical direction, and the plurality of air holes form a spiral structure spiraling upward in a clockwise / counterclockwise direction with the spiral guide plates.

[0014] As a preferred embodiment, the pores are arranged at equal intervals in the horizontal direction.

[0015] As a preferred embodiment, the pores are equidistantly arranged in the vertical direction.

[0016] As a preferred embodiment, the top of the housing is provided with a through hole for mounting a lighting lamp.

[0018] As a preferred embodiment, the sidewall extends upward from the top edge to form a rim, and the inner side of the rim is provided with a second snap-fit ​​block for suspended installation.

[0019] The beneficial effects of this utility model are as follows: 1. By installing a fan on the side wall of the lamp housing, a negative pressure is generated inside the housing, drawing in air from below and blowing it onto the oxygen pad on the outside of the housing. Integrating the housing and fan achieves synergy between effective lighting and rapid oxygen supply, avoiding the need for excessive space. 2.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] To facilitate understanding, the present invention will now be described in further detail with reference to specific implementation examples, but this is not intended to limit the present invention.

[0028] like Figure 1-4 As shown, this utility model discloses a lamp housing capable of generating eddies, including a cylindrical housing 1 with a downward-facing opening 101 for downward illumination. A fan 2 is provided on the side wall 102 of the housing 1 to create negative pressure inside. In a confined space, because carbon dioxide is denser than oxygen and nitrogen, there is more carbon dioxide in the lower-lying air. Air below the housing 1 is drawn into the housing 1 through the opening under the negative pressure and discharged from the side wall 102 by the fan 2. The fan 2 blows the air towards an oxygen fin on the outside of the housing 1, causing the carbon dioxide in the air to react rapidly with the oxygen fin to produce oxygen. Integrating the housing 1 and the fan 2 achieves synergy between effective lighting and rapid oxygen supply, avoiding the need for a large space. The air is discharged from the side wall by the fan 2, which blows the air towards the oxygen fin on the outside of the housing.

[0029] The main components of the oxygen tablets are potassium superoxide or sodium peroxide. Oxygen tablets are commonly used to supply oxygen in mine emergency rescue. In this embodiment, the oxygen tablets are flat and round. When in use, a ventilated frame or cage is suspended on the outside of the housing 1, and the oxygen tablets are placed in the frame or cage. The fan blows the air drawn up from below the housing onto the oxygen tablets in the frame or cage, accelerating the reaction rate of carbon dioxide in the air with the oxygen tablets to produce oxygen.

[0030] In this embodiment, there are two fans 2, which are arranged radially on the side wall 102 of the housing 1 and are positioned opposite each other. By providing two fans 2, the negative pressure inside the housing 1 is increased.

[0031] In order to enable the carbon dioxide drawn up by the negative pressure to fully react with the oxygen tablet, the side wall 102 is provided with a number of air holes 104 for the air inside the shell 1 to flow with the outside air. Since the negative pressure is formed inside the shell 1 under the action of the fan 2, some of the air outside the shell 1 flows back into the shell 1 from the air holes 104 under the negative pressure, and then is blown out by the fan 2 to react with the oxygen tablet.

[0032] To further improve the efficiency of the housing 1 in drawing in air from below, the inner side of the side wall 102 is provided with a number of spiral guide plates 105 spiraling from bottom to top in a clockwise / counterclockwise direction. The spiral guide plates 105 are equidistant from each other, and a number of air holes 104 are arranged along the spiral extension direction of the spiral guide plates 105. The spiral guide plates 105 separate the adjacent air holes 104 in the vertical direction, and the number of air holes 104 form a spiral structure from bottom to top in a clockwise / counterclockwise direction with the spiral guide plates 105.

[0033] In this embodiment, several pores are equidistantly arranged in the horizontal direction, and several pores are also equidistantly arranged in the vertical direction.

[0034] The spiral guide vane 105 guides the air flowing back through the air hole 104 under negative pressure, forming a vortex, accelerating the gas intake from below, and improving the oxygen supply efficiency of the fan 2 to the oxygen plate.

[0035] In this embodiment, the top 103 of the housing 1 is provided with a through hole 106 for mounting a lighting lamp.

[0036] When this embodiment is used for a floor lamp, a first snap-fit ​​block 107 for floor mounting is provided on the lower inner side of the side wall 102.

[0037] When this embodiment is used for a ceiling light, the side wall 102 extends upward from the edge of the top 103 to form a rim 108, and the inner side of the rim 108 is provided with a second snap-fit ​​block 109 for hanging installation.

[0038] In practical applications, the number of fans 2 is not limited to two; it can also be three or four.

[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
