Description

Technical Field

[0001] The present invention relates to an emergency drenching and eyewash device with a dynamic balance valve. Background Art

[0002] An eyewash device is used in emergency situations to temporarily slow down the further invasion of harmful substances into the body when toxic and harmful substances splash onto the body, face, or eyes of workers, or when a fire causes the clothing of workers to catch fire. Further treatment and care need to follow the guidance of a doctor to avoid or reduce unnecessary accidents. During the treatment and care process of ophthalmology, eye irrigation is often required. Currently, the eyewash devices used clinically include wall-mounted and floor-standing models.

[0003] For current eyewash devices, the water pressure completely depends on the external water pressure. If the external water pressure suddenly increases, it may cause damage to the human eye. Therefore, it is necessary to make improvements. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an emergency drenching and eyewash device with a dynamic balance valve, which can avoid the influence of external water pressure changes on flushing.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an emergency drenching and eyewash device with a dynamic balance valve, including a water pipe. A shower head is connected to the top of the water pipe. A branch pipe is communicated at the middle position of the water pipe. A spray head is arranged at the end of the branch pipe. An inlet is arranged in the area between the shower head and the branch pipe of the water pipe. A first balance valve is arranged below the inlet. The first balance valve includes a first cylinder with an open end at one end and a first spring. Several first water inlet grooves communicating with the inner wall are arranged on the outer ring of the first cylinder. A first sealing ring is arranged on the inner wall of the water pipe. The inner ring of the first sealing ring is in close contact with the outer wall of the first cylinder. The first spring pushes the first cylinder in the direction opposite to the direction of water flow. When in use, on the one hand, water flows upward through the water pipe into the shower head to spray the user's head. On the other hand, it flows downward, passes through the first balance valve and then enters the branch pipe to wash the person's eyes. When the water flow passes through the first balance valve, if the external flow rate is large, it will push the first cylinder to move along the water flow against the elastic force of the spring. In this way, part of the first water inlet groove at the water flow inlet will be blocked by the sealing ring, so that the water flow rate will be reduced, thereby reducing the pressure of the water flow entering the branch pipe and avoiding damage to the human eye.

[0006] In the above technical solution, preferably, the water pipe includes a first combined pipe, a second combined pipe, and a third combined pipe. The shower head is connected to the first combined pipe, the water inlet is arranged on the second combined pipe, and the branch pipe is connected to the third combined pipe. A first connecting member is arranged between the first combined pipe and the second combined pipe, a second connecting member is arranged between the second combined pipe and the third combined pipe, and the first balance valve is arranged at the second connecting member.

[0007] In the above technical solution, preferably, the second connecting member includes a first connecting block and a second connecting block. The first connecting block is connected to the second combined pipe, the second connecting block is connected to the third combined pipe, and the first connecting block and the second connecting block are connected by a nut.

[0008] In the above technical solution, preferably, a second sleeve is fixed on the second connecting block, the first spring is arranged in the second sleeve, and the first sealing ring is fixed at the top of the second sleeve.

[0009] In the above technical solution, preferably, the first connecting member includes a third connecting block and a fourth connecting block. The third connecting block is connected to the first combined pipe, the fourth connecting block is connected to the second combined pipe, and the third connecting block and the fourth connecting block are connected by a double-headed screw sleeve.

[0010] In the above technical solution, preferably, a second balance valve is further included. The second balance valve is arranged at the first connecting member. The second balance valve includes a second cylinder with one end open. A plurality of second water inlet grooves communicating with the inner wall are arranged on the outer ring of the second cylinder. A first sleeve is fixed on the first combined pipe. A second spring is arranged in the first sleeve. A second sealing ring is arranged at the top of the first sleeve. The second sealing ring is in close contact with the second cylinder. The second spring pushes the second cylinder in the reverse direction of the water flow. During use, the water flow passes through the second water inlet grooves and enters the first combined pipe, and then is sprayed downward through the shower head. If the water pressure at the inlet is relatively large, it will push the second cylinder to move into the first sleeve, so that part of the second water inlet grooves will be blocked, the amount of water inlet will be reduced, and the pressure entering the first combined pipe will be reduced, avoiding a sharp rise in the water pressure hitting the person's head.

[0011] The beneficial effects of the present invention are as follows: When in use, on the one hand, water flows upward through the water pipe into the shower head to spray the user's head, and on the other hand, it flows downward, passes through the first balance valve and then enters the branch pipe to wash the person's eyes. When the water flow passes through the first balance valve, if the external flow rate is large, it will push the first cylinder to move along the water flow against the elastic force of the spring. In this way, part of the first water inlet groove at the water flow inlet will be blocked by the sealing ring, so that the water flow rate will be reduced, thereby reducing the pressure of the water flow entering the branch pipe and avoiding damage to the human eyes.

[0019] An inlet 12 is arranged in the area between the shower head and the branch pipe of the water pipe 1, and a first balance valve 4 is arranged below the inlet 12.

[0020] The first balance valve 4 includes a first cylinder 41 with an open end and a first spring 44. A plurality of first water inlet grooves 42 communicating with the inner wall are arranged on the outer ring of the first cylinder 41. A first sealing ring 43 is arranged on the inner wall of the water pipe 1. The inner ring of the first sealing ring 43 is in close contact with the outer wall of the first cylinder 41. The first spring 44 pushes the first cylinder 41 in the direction opposite to the flow direction of the water flow.

[0021] During use, on the one hand, the water flow passes upward through the water pipe into the shower head to spray the user's head. On the other hand, it flows downward, passes through the first balance valve and then enters the branch pipe to rinse the person's eyes. When the water flow passes through the first balance valve, if the external flow rate is large, it will push the first cylinder to move along the water flow against the elastic force of the spring. In this way, part of the first water inlet groove at the water flow inlet will be blocked by the sealing ring, so that the water flow rate will be reduced, thereby reducing the pressure of the water flow entering the branch pipe and avoiding harm to the human eyes.

[0022] The water pipe 1 includes a first combined pipe 13, a second combined pipe 14 and a third combined pipe 15. The shower head 2 is connected to the first combined pipe 13. The water inlet 12 is arranged on the second combined pipe 14. The branch pipe 11 is connected to the third combined pipe 15. A first connecting piece 5 is arranged between the first combined pipe 13 and the second combined pipe 14. A second connecting piece 6 is arranged between the second combined pipe 14 and the third combined pipe 15. The first balance valve 4 is arranged at the second connecting piece 6.

[0023] The second connecting piece 6 includes a first connecting block 61 and a second connecting block 62. The first connecting block 61 is connected to the second combined pipe 14. The second connecting block 62 is connected to the third combined pipe 15. The first connecting block 61 and the second connecting block 62 are connected by a nut 63.

[0024] A second sleeve 64 is fixed on the second connecting block 62. The first spring 44 is arranged in the second sleeve 64. The first sealing ring 43 is fixed at the top of the second sleeve 64.

[0025] The first connecting piece 5 includes a third connecting block 51 and a fourth connecting block 52. The third connecting block 51 is connected to the first combined pipe 13. The fourth connecting block 52 is connected to the second combined pipe 14. The third connecting block 51 and the fourth connecting block 52 are connected by a double-headed screw sleeve 53.

[0026] It further includes a second balance valve 7, which is arranged at the first connecting piece 5. The second balance valve 7 includes a second cylinder 71 with an open end. A plurality of second water inlet grooves 72 communicating with the inner wall are arranged on the outer circle of the second cylinder 71. A first sleeve 75 is fixed on the first combined pipe 13. A second spring 74 is arranged inside the first sleeve 75. A second sealing ring 73 is arranged at the top of the first sleeve 75. The second sealing ring 73 is in close contact with the second cylinder 71. The second spring 74 pushes the second cylinder 71 in the reverse direction of the water flow.

[0027] During use, water flows into the first combined pipe through the second water inlet groove and is then sprayed downward through the shower head. If the water pressure at the inlet is relatively large, it will push the second cylinder to move into the first sleeve. In this way, part of the second water inlet groove will be blocked, the water intake will decrease, and the pressure entering the first combined pipe will decrease, avoiding a sharp rise in the water pressure hitting the head.
