Detailed Description

The specific embodiments illustrated below are intended as descriptions of various configurations of the presently disclosed subject technology and are not intended to represent the only configurations in which the presently disclosed subject technology may be practiced. Specific embodiments include specific details for the purpose of providing a thorough understanding of the presently disclosed subject matter technology. It will be apparent, however, to one skilled in the art that the disclosed subject matter technology is not limited to the specific details shown herein and may be practiced without these specific details.

Referring to fig. 1 to 5, a personnel protection type fire-fighting lance for clean rooms includes a body 1, wherein one end of the body 1 is provided with a water hose connector 2, the other end of the body 1 is provided with a nozzle 3, the nozzle 3 is connected to the body 1 through a thread, the body 1 has a water passage 101, the water hose connector is communicated with the nozzle 3 through the water passage 101, the body 1 is provided with a protector 4, the protector 4 sprays water along a diameter direction of the body 1 to form a water wall, the protector 4 includes a nozzle hole 401 disposed on the body 1, a slide ring 402 covering the nozzle hole 401, and a switch rod 403 for operating the displacement of the slide ring 402, the nozzle hole 401 is communicated with the water passage 101, a part of water in the water passage 101 flows through the nozzle hole 401 to form the water wall, and the slide ring 402 is slidably connected to the body 1, the body 1 is provided with a handle 102, the switch rod 403 is rotatably connected to the handle 102 and controls the sliding ring 402 to cover or separate from the spray hole 401, and the body 1 is further provided with a spring 404 for enabling the sliding ring 402 to cover the spray hole 401.

In actual use, the water hose connector 2 is connected with a water hose, liquid supplied in the water hose enters the water flow channel 101 through the water hose connector 2, and the liquid supplied in the water hose is usually water. The liquid in the water flow channel 101 is sprayed out through the spray head 3, and the general spray head 3 sprays the liquid to the root of the fire source to play a role in quickly extinguishing fire. In case of a fire with a large fire, a fire fighter is required to approach the fire source, and at this time, the fire fighter may be burned due to heat radiation of the fire source. In order to prevent the fire fighter from being burned, the fire fighter can operate the switch lever 403 to separate the sliding ring 402 from the spray holes 401, at this time, a part of the liquid in the water flow channel 101 can be sprayed out through the spray holes 401, and because the spray holes 401 spray out the water flow along the diameter direction of the body 1, the water flow sprayed out from the spray holes 401 can form a water wall between the fire source and the fire fighter, and the water wall can effectively protect the fire fighter from being burned.

The water wall formed by the spray holes 401 should be as close as possible, and therefore, as many spray holes 401 as possible should be arranged on the circumference of the body 1 to optimize the performance of the water wall and achieve the function of better protecting the firefighters.

The spray head 3 is connected with the body 1 through threads, and the spray head 3 can be conveniently replaced, so that the fire extinguisher can adapt to different fires. In practice, this scheme is particularly useful for the toilet, because the passageway of toilet is narrow, the conflagration of taking place easily, and in the process of putting out a fire the fire personnel must put out a fire in narrow space relatively again, and the fire personnel change the root that is close the burning things which may cause a fire disaster, and simultaneously, the fire personnel arrive thermal radiation's injury more easily, consequently, this scheme is particularly useful for the toilet.

In some embodiments, the sliding ring 402 is assembled on the body 1 through a limiting ring 405, the limiting ring 405 is fixed on the body 1 through threads, the sliding ring 402 has a containing cavity 406 containing the limiting ring 405, at least a part of the limiting ring is located in the containing cavity 406, one end of the spring 404 abuts against the sliding ring 402, and the other end of the spring 404 abuts against the limiting ring 405.

The spacing ring 405 is provided with the internal thread, body 1 be provided with internal thread fit's on the spacing ring 405 external screw thread, the spacing ring 405 is located the part outside holding chamber 406 is provided with and is convenient for rotate the ring flange 4051 of spacing ring 405, the ring flange 4051 with spacing ring 405 formula structure as an organic whole.

The stop collar 405 may or may not be in contact with the slip ring 402, since the stop collar 405 only functions to position the slip ring 402 via the spring 404, whether the stop collar 405 is in contact with the slip ring 402 may be achieved.

The guard 4 has better stability when the stop collar 405 is in contact with the slip ring 402. However, when the slip ring 402 comes into contact with the retainer ring 405, the resistance to displacement of the slip ring 402 may increase, and in this case, a lubricating layer may be applied between the slip ring 402 and the retainer ring 405.

The stop collar 405 should be assembled with the body 1 in a detachable manner. The limiting ring 405 and the body 1 can be fixed by a clamp spring besides adopting threaded connection. The actual assembly of the stop collar 405 to the body 1 is not limited and can be freely designed by those skilled in the art.

In some embodiments, the switch lever 403 includes a control portion 4031, an operating portion 4032, and a connecting portion located between the control portion 4031 and the operating portion 4032, the control portion 4031, the operating portion 4032, and the connecting portion are of an integrated structure, the switch lever 403 is rotatably connected to the handle 102 through a rotating shaft 4033, and a shaft hole engaged with the rotating shaft 4033 is provided in the connecting portion.

The handle 102 is provided with two lugs 1021 for mounting the switch lever 403, a mounting cavity is formed between the two lugs 1021, at least a part of the connecting part is located in the mounting cavity, and through holes matched with the rotating shaft 4033 are formed in the lugs 1021. The lug 1021 and the handle 102 may be a unitary structure. The handle 102 and the body 1 may be of one-piece construction.

The number of handles 102 may be one or more to facilitate the operation of a clean room personal protective fire water gun. The switch lever 403 has only one, and when the handle 102 has a plurality of levers, the switch lever 403 is provided on one of the handles 102.

Two ends of the rotating shaft 4033 can be limited by nuts to prevent the rotating shaft 4033 from separating from the shaft hole. The two ends of the rotating shaft 4033 can also be limited by riveting parts. The limit mode of the rotating shaft 4033 is not limited and can be freely selected.

In some embodiments, the control portion 4031 has an inclined surface, the inclined surface contacts one end surface of the slip ring 402, the inclined surface is provided with a protruding point which reduces the contact area of the inclined surface and the slip ring 402, the protruding point is shaped like a hemisphere, and the protruding point and the control portion 4031 are of an integrated structure.

The end face of the slip ring 402 contacting with the inclined face is a guide face 4021 with guiding capability, and the guide face 4021 is arranged obliquely. This spigot 4021 can make the waterwall slope to the fire fighter's place ahead to further optimize the application performance of the personnel protection type fire-fighting lance for the clean room.
