Description

Technical Field

[0001] The invention relates to a necessary equipment for safety and labor protection, in particular to an eyewasher capable of controlling water outlet pressure in real time. Background Art

[0002] Emergency shower eyewash is an essential equipment for safety and labor protection. It is an essential emergency and protective measure in situations where there is contact with toxic and corrosive substances such as acids, alkalis, and organic matter. When these harmful substances splash into people's eyes, skin, etc. and cause accidental injury, the degree of injury can be minimized through rapid spraying and flushing. There are many laboratories in colleges and universities that involve acids, alkalis and toxic chemicals. Emergency shower eyewashes are generally directly connected to the tap water pipe, but the pressure of the shower water of these eyewashes cannot be adjusted or regulated, which is very inconvenient. The pressure of the shower water of these eyewashes depends directly on the pressure of the water in the tap water pipe. The greater the pressure of the tap water, the greater the pressure of the shower water, and the smaller the pressure of the tap water, the smaller the pressure of the shower water. The pressure of the tap water is different for different geographical locations and different floors. However, the impact pressure of the water flow that people's eyes can withstand needs to be controlled within a certain range. If the pressure of the shower water is too small, the effect of the shower becomes worse. If the pressure of the shower water is too high, it will also cause secondary damage to the eyes. When the damage occurs, the pressure of the shower water is generally higher when the flushing starts, and the pressure of the water is lower when the flushing continues. That is, people need to adjust the pressure of the eyewash water outlet conveniently, quickly and directly. Summary of the invention

[0003] The purpose of the present invention is to solve the problems in the prior art and to provide an eyewash device which is easy to operate and can quickly and directly adjust the water pressure of the eyewash device in real time according to needs during use.

[0004] The objective of the present invention is achieved through the following technical solutions:

[0005] The eyewash device for controlling water outlet pressure in real time of the present invention comprises a connecting pipe 1, a first clamping ring 3, a control spherical surface 4, a switch seat 5, a translation pipe 6, a water spray head 7, a moving hole 8, a second clamping ring 9, a spray hole 10, a fixing hole 11, a guide rod 12, a screw 13, a guide cylinder 14, a pressurizing hole 15, and a rubber sleeve 16.

[0006] The left end of the connecting pipe 1 is connected to the water outlet pipe of the tap water, and the right end is fixedly connected to the switch seat 5. The control spherical surface 4 is sleeved on the outside of the connecting pipe 1. The left end is fixed to the middle part of the connecting pipe 1 through the first clamping ring 3, and the right end is fixedly connected to the left end of the translation pipe 6 through the second clamping ring 9. The right end of the translation pipe 6 is connected to the sprinkler head 7.

[0007] The connecting pipe 1 is made of a cylindrical high-quality plastic pipe, and a first annular groove 17 is formed on the outer edge of the middle of the cylinder. The left end of the control spherical surface 4 is embedded in the first annular groove 17 and fixed by the first clamping ring 3. The connecting pipe 1 is provided with uniformly distributed boosting holes 15 on the middle circumference.

[0008] The switch seat 5 is a rotating body cylinder cover with a guide cylinder 14 in the center. An internal thread 19 is formed on the inner circumference of the cylinder cover. The internal thread 19 is connected to the external thread 18 at the right end of the connecting pipe 1 to fix the switch seat 5 on the connecting pipe 1. Fixing holes 11 are evenly distributed on the disc-shaped plane of the right end of the switch seat 5 near the outer edge.

[0009] The translation tube 6 is a cylinder made of high-quality plastic. The left end face of the cylinder of the translation tube 6 is a disc. The center of the disc has a stepped hole 21, and moving holes 8 are evenly distributed around the stepped hole 21. A second annular groove 20 is formed on the outer circumferential surface of the disc. The right end of the control spherical surface 4 is embedded in the second annular groove 20 and fixed by a second retaining ring 9.

[0010] The disk-shaped plane at the right end of the switch seat 5 and the disk-shaped plane at the left side of the translation tube 6 are both covered with magnetic film material. Under the elastic tension of the control spherical surface 4 and the attraction of the magnetic film material, the disk-shaped plane at the right end of the switch seat 5 and the disk-shaped plane at the left side of the translation tube 6 are tightly fitted together, the fixing hole 11 and the moving hole 8 are staggered, and the disk-shaped plane at the left side of the translation tube (6) closes the fixing hole (11), so that the tap water in the connecting pipe 1 cannot enter the inside of the shower head 7.

[0011] The end of the translation tube 6 is provided with a flange 22 .

[0012] The control spherical surface 4 is an ellipsoidal surface, and is made of a highly elastic food-grade rubber material;

[0013] The guide rod 12 is inserted into the circular hole of the guide cylinder 14 of the switch seat 5, and the right end passes through the guide cylinder 14 and is inserted into the stepped hole 21 in the center of the translation tube 6, and the guide rod 12 is fixed to the translation tube 6 by the screw 13. The guide rod 12 and the inner hole of the guide cylinder 14 are clearance-matched. When the control spherical surface 4 is held by hand and pressure is applied to the control spherical surface 4, the convex spherical surface of the control spherical surface 4 is flattened and elongated, pushing the translation tube 6 to move along the direction of the guide rod 12, and the disc-shaped plane at the right end of the switch seat 5 and the disc-shaped plane on the left side of the translation tube 6 move away from each other. The tap water in the connecting pipe 1 and the tap water stored in the control spherical surface 4 flow into the interior of the sprinkler head 7 along the fixed hole 11 at the upper end of the switch seat 5 and the movable hole 8 at the bottom of the translation tube 6.

[0014] The watering head 7 is an ellipsoid made of high-quality rubber material, and the ellipsoid has spray holes 10 evenly distributed on the ellipsoid. The left end of the watering head 7 is sleeved on the right end of the translation tube 6 through a rubber sleeve 16, and the rubber sleeve 16 is fixed in the flange 22 of the translation tube 6.

[0015] A thrust ring 2 is provided on the left end of the connecting pipe 1 .

[0016] It can be seen from the technical solution provided by the present invention that the beneficial effects of the eyewash with real-time control of water pressure described in the present invention are: water does not need to move the switch, when the control spherical surface 4 is held by hand and pressure is applied to the control spherical surface 4, the convex spherical surface of the control spherical surface 4 is flattened and stretched, pushing the translation tube 6 to move along the axial direction of the guide rod 12, and the tap water in the connecting tube 1 and the tap water stored in the control spherical surface 4 flow into the inside of the shower head 7 along the fixed hole 11 at the upper end of the switch seat 5 and the moving hole 8 at the left end of the translation tube 6, and are sprayed out from the spray hole 10 on the shower head 7. When the control spherical surface 4 is tightly held, the distance between the disc-shaped plane at the right end of the switch seat 5 and the disc-shaped plane on the left side of the translation tube 6 increases, the water flow resistance decreases, and the pressure of the water sprayed from the shower head 7 increases. On the contrary, the water pressure of the shower head 7 decreases until it is closed. The emergency sprayer can control the water pressure of the eyewash in real time according to the water pressure of the tap water pipe and the actual situation of the individual.

DETAILED DESCRIPTION

[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, an eyewash device for real-time control of water outlet pressure of the present invention includes a connecting pipe 1, a first clamping ring 3, a control spherical surface 4, a switch seat 5, a translation tube 6, a water head 7, a moving hole 8, a second clamping ring 9, a spray hole 10, a fixing hole 11, a guide rod 12, a screw 13, a guide cylinder 14, a pressurizing hole 15, and a rubber sleeve 16.

[0030] The left end of the connecting pipe 1 is connected to the water outlet pipe of the tap water, and the right end is fixedly connected to the switch seat 5. The control spherical surface 4 is sleeved on the outside of the connecting pipe 1. The left end is fixed to the middle part of the connecting pipe 1 through the first clamping ring 3, and the right end is fixedly connected to the left end of the translation pipe 6 through the second clamping ring 9. The right end of the translation pipe 6 is connected to the sprinkler head 7.

[0031] The connecting pipe 1 is made of a cylindrical high-quality plastic pipe, and a first annular groove 17 is formed on the outer edge of the middle of the cylinder. The left end of the control spherical surface 4 is embedded in the first annular groove 17 and fixed by the first clamping ring 3. The middle circumference of the connecting pipe 1 is provided with uniformly distributed boosting holes 15.

[0032] The switch seat 5 is a rotary cylinder cover with a guide sleeve 14 in the center. An internal thread 19 is formed on the inner circumference of the cylinder cover. The internal thread 19 is connected to the external thread 18 at the right end of the connecting pipe 1 to fix the switch seat 5 on the connecting pipe 1. Fixing holes 11 are evenly distributed on the disc-shaped plane of the right end of the switch seat 5 near the outer edge.

[0033] The translation tube 6 is a cylinder made of high-quality plastic. The bottom surface of the cylinder on the left side of the translation tube 6 is a disc-shaped disk with a stepped hole 21 in the center of the disc. Moving holes 8 are evenly distributed around the stepped hole 21. A second annular groove 20 is formed on the outer circumferential surface of the disc. The right end of the control spherical surface 4 is embedded in the second annular groove 20 and fixed by a second retaining ring 9.

[0034] The change in position of the movable hole 8 on the translation tube 6 relative to the fixed hole 11 on the switch seat 5 can form the opening and closing of the tap water. In order to make the switch tight and prevent water leakage, the disc-shaped plane on the right end of the switch seat 5 and the disc-shaped plane on the left side of the translation tube 6 are both attached with magnetic film materials. Under the elastic tension of the control spherical surface 4 and the attraction of the magnetic film material, the disc-shaped plane on the right end of the switch seat 5 and the disc-shaped plane on the left side of the translation tube 6 are tightly fitted together. Because the fixed hole 11 and the movable hole 8 are staggered relative to each other, the left end disc of the translation tube closes the fixed hole 11, and the tap water in the connecting pipe 1 cannot enter the inside of the shower head 7.

[0035] In order to prevent the axis of the translation tube 6 from being deflected during the movement, a guide rod 12 is fixedly connected to the left end of the translation tube 6, and the guide rod 12 is inserted into the circular hole of the guide cylinder 14 of the switch seat 5. The right end passes through the guide cylinder 14 and is inserted into the stepped hole 21 in the center of the translation tube 6, and the guide rod 12 is fixed to the translation tube 6 by a screw 13. The guide rod 12 and the inner hole of the guide cylinder 14 are clearance-matched. When the control spherical surface 4 is held by hand and pressure is applied to the control spherical surface 4, the convex spherical surface of the control spherical surface 4 is flattened and elongated, pushing the translation tube 6 to move along the direction of the guide rod 12, and the disc-shaped plane at the right end of the switch seat 5 and the disc-shaped plane on the left side of the translation tube 6 move away from each other. The tap water in the connecting pipe 1 and the tap water stored in the control spherical surface 4 flow into the inside of the sprinkler head 7 along the fixed hole 11 at the upper end of the switch seat 5 and the movable hole 8 at the bottom of the translation tube 6.

[0036] The sprinkler head 7 is an ellipsoidal surface made of a high-quality rubber material tube, and the ellipsoidal surface is evenly distributed with spray holes 10. The left end of the sprinkler head 7 is sleeved on the right end of the translation tube 6 through a rubber sleeve 16, and the rubber sleeve 16 is clamped in the flange 22 of the translation tube 6 and fixed.

[0037] In order to prevent air from being stored in the control spherical surface 4 and affecting the outflow of tap water when pressure is applied to the control spherical surface 4, a pressurizing hole 15 is radially formed on the connecting pipe 1 closed by the control spherical surface 4, so that the inside of the control spherical surface 4 is always filled with tap water. When pressure is applied to the control spherical surface 4, the water in the control spherical surface 4 flows into the connecting pipe 1 through the pressurizing hole 15, so that the water pressure in the connecting pipe 1 is further enhanced, quickly filling the inside of the shower head 7, and quickly spraying the corresponding parts of the human body.

[0038] In order to ensure that the sprinkler head 7 is installed firmly, the end of the translation tube 6 is provided with a flange 22 , and the flange 22 clamps the rubber sleeve 16 after the rubber sleeve 16 is sleeved on the translation tube.

[0039] The control spherical surface 4 and the water spray head 7 are both made of high-quality rubber material with no toxic or side effects.

[0040] When the rubber hose of the tap water is connected to the connecting pipe 1 , the rubber hose is sleeved on the thrust ring 2 at the left end of the connecting pipe 1 .

[0041] When you need to wash your eyes, you can grab the eyewash directly. Figure 2 As shown, the control spherical surface 4 is held by hand and pressure is applied thereto. Under the pressure of the hand, the convex spherical surface of the control spherical surface 4 is flattened and stretched, pushing the translation tube 6 to move along the axial direction of the guide rod 12. The tap water in the connecting pipe 1 and the tap water stored in the control spherical surface 4 flow into the interior of the sprinkler head 7 along the fixed hole 11 at the upper end of the switch seat 5 and the movable hole 8 at the bottom of the translation tube 6, and are sprayed out from the spray hole 10 on the sprinkler head 7. The control spherical surface 4 is held tightly, and the distance between the disc-shaped plane at the right end of the switch seat 5 and the disc-shaped plane on the left side of the translation tube 6 increases, the water flow resistance decreases, and the water pressure from the sprinkler head 7 increases. On the contrary, the pressure on the control spherical surface 4 is reduced. The pressure on the surface 4 is increased because the distance between the disc-shaped plane at the right end of the switch seat 5 and the disc-shaped plane on the left side of the translation tube 6 is reduced. The tap water has to flow into the water head 7 through the narrow space between the disc-shaped plane at the right end of the switch seat 5 and the disc-shaped plane on the left side of the translation tube 6, then the resistance of the water flow is increased, and the water outlet pressure of the water head 7 is reduced. The user can quickly and directly adjust the pressure of the flushing water of the eyewash according to their own needs. For example, the pressure of the flushing water can be larger at the beginning of flushing, and the pressure of the water outlet can be smaller during continuous flushing. It is very convenient to realize real-time control of the water outlet pressure of the eyewash to achieve the best spraying effect.

[0042] Compared with the prior art, the eyewash device designed in this invention which controls the water outlet pressure in real time has the following characteristics.

[0043] 1. Easy to operate. Just hold the eyewash station with your hand to spray. It will automatically shut down after you let go. There will be no situation where you can't touch the switch and can't open the eyewash station. After spraying and washing, you will not forget to turn it off and the water will flow all over the floor, which will not cause waste and will not harm the environment.

[0044] 2. The size of the spray water flow can be adjusted in real time to achieve the best spray effect.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
