Description
Technical Field
The invention relates to the technical field of electricity-proof walls, in particular to an electricity-proof plug.
Background
The electricity-proof wall is usually installed inside or outside the water inlet and/or outlet of an electric water heating device (such as a water storage type electric water heater or a hot water tank), and the leakage current is attenuated by using a water resistor, so that the leakage protection effect is achieved. The traditional bushing type electricity-proof wall is usually formed by sleeving a stainless steel pipe outside an insulating pipe, the effective damping length of the electricity-proof wall with the structure is the length of the insulating pipe, so that a sufficient water resistance is formed, the integral linear size of a product needs to be designed to be long enough, the electricity-proof wall is limited by the size of a parent body (such as an inner container of electric water heating equipment) due to the fact that the linear size is too long when the electricity-proof wall is installed, and the universal adaptability is poor.

In view of the above, it is necessary to provide an electricity-proof plug which can pass water and has sufficient water resistance to form a safe and electricity-proof protective barrier, and has a short overall linear dimension and strong general adaptability.

And because the core pipe and the outer blind pipe both adopt insulating pipes, the effective damping length of the water resistance of the electricity-proof plug is the sum of the length of the core pipe and the length of part of the pipe section of the outer blind pipe (namely the pipe section from the closed end of the outer blind pipe to the position before the water distribution hole), so that the enough effective damping length can be obtained only by matching the relatively short core pipe and the outer blind pipe, the integral linear dimension of the electricity-proof plug can be shortened, the installation of the electricity-proof plug is not limited by the size of a parent body, and the electricity-proof plug has strong universal adaptability.

Referring to fig. 1 to 3, an electricity-proof plug 10 includes a core tube 11 and an outer blind tube 12, the core tube 11 is a through tube with two open ends, the outer blind tube 12 is a blind tube with one open end and one closed end, the outer blind tube 12 is sleeved on the periphery of the core tube 11 and forms a gap 101 with the core tube 11, the orifice of the outer blind tube 12 is hermetically connected with a first end 111 of the core tube 11, a second end 112 of the core tube 11 is suspended and inserted in the outer blind tube 12 and is communicated with the gap 101, a water distribution hole 120 communicated with the gap 101 is arranged on a tube section of the outer blind tube 12 close to the first end 111, and both the outer blind tube 12 and the core tube 11 are insulating tubes.
The outer blind pipe 12 and the core pipe 11 may be made of an insulating material such as a plastic material, a rubber material, or a silica gel material, and the outer blind pipe 12 and the core pipe 11 may be made of the same insulating material or different insulating materials, which is not limited herein. Optionally, an insulating fiber material may be added to the insulating material to improve the structural strength of the outer blind pipe 12 and/or the core pipe 11. The pipe orifice of the outer blind pipe 12 and the outer peripheral surface of the first end 111 of the core pipe 11 may form an integral sealing connection structure by means of bonding, pressing, or the like, or may also realize sealing connection by a sealing member. The water distribution holes 120 on the outer blind pipe 12 can be circular holes, strip-shaped holes, square holes or other special-shaped holes.
When the electricity plug 10 is filled with water, water flow can enter the core tube 11 from the tube opening of the first end part 111 of the core tube 11, flow into the gap 101 between the outer blind tube 12 and the core tube 11 through the tube opening of the second end part 112 of the core tube 11, and finally flow out from the water distribution holes 120 on the outer blind tube 12, or the water flow can also flow reversely; when the electric water heater leaks electricity, the leakage current can be automatically attenuated to a safe index (generally, the leakage current is ensured to be less than or equal to 2mA) which can be borne by a human body, so that a safe and isolated protective barrier is formed. And because the core tube 11 and the outer blind tube 12 both adopt insulating tubes, the effective damping length of the water resistance of the electricity-proof plug 10 is the sum of the length of the core tube 11 and the length of a part of tube sections of the outer blind tube 12 (namely, the tube sections from the closed end of the outer blind tube 12 to the front of the water distribution hole 120), so that the enough effective damping length can be obtained only by adopting the relatively short core tube 11 and the outer blind tube 12 to be matched, the integral linear size of the electricity-proof plug 10 can be shortened, the installation of the electricity-proof plug is not limited by the size of a parent body, and the electricity-proof plug has strong universal adaptability.
In addition, when the water flow velocity is too large, the outer blind pipe 12 and the core pipe 11 are easy to vibrate, and the second end 112 of the core pipe 11 is suspended and inserted into the outer blind pipe 12 and is not rigidly connected with the outer blind pipe 12, so that the core pipe 11 can generate a certain swing amplitude to perform self-adaptive adjustment, and the core pipe 11 can be prevented from being broken, the service life of the product can be prolonged, the integral structure of the product is simpler, and the assembly is convenient.
Referring to fig. 3 and 4, in one embodiment, the outer blind pipe 12 includes a water delivery pipe section 121 and a water distribution pipe section 122 which are communicated with each other, the water distribution pipe section 122 is disposed near the first end 111, and the outer periphery of the water distribution pipe section 122 is provided with a water distribution pipeA plurality of water distribution holes 120, the core pipe 11 is an equal-diameter through pipe, the radius of the inner hole of the core pipe 11 is r, the length of the core pipe 11 is L1, the length of the water delivery pipe section 121 is L2, wherein L1+ L2 is not less than 53r2. The sum of L1 and L2 is the effective damping length of the water resistor, so that the leakage current in the water flowing in and out of the path can be effectively ensured to be less than or equal to 2mA, and the safety and reliability of the electricity-proof plug 10 are ensured. The plurality of water distribution holes 120 are arranged along the circumferential direction of the water distribution pipe section 122, so that cold water at the water inlet pipe can be uniformly dispersed into hot water of hot water equipment, the impact force of water flow is reduced, and the functions of dispersion and buffering are achieved.
Preferably, the cross-sectional area of the gap 101 is equal to or slightly larger than the cross-sectional area of the inner bore of the core tube 11; and/or the sum of the areas of the plurality of water distribution holes 120 is equal to or larger than the sectional area of the gap 101. So, can further reduce cold water velocity of flow, play and disperse and the decompression effect, avoid cold water to the impact of hot water, guarantee hot water output rate.
In one embodiment, the outer blind pipe 12 and/or the core pipe 11 is an insulating rubber pipe made of an insulating rubber material. For example, the core tube 11 may be made of an insulating rubber tube, the outer blind tube 12 may be made of an insulating plastic tube, and the outer blind tube 12 has a high strength and can play a certain role in protection. For another example, the core tube 11 and the outer blind tube 12 may both be made of insulating rubber tubes, so that the electricity-proof plug 10 has good overall elasticity and is free to bend, and the outer blind tube 12 and the core tube 11 may be axially bent and coiled, so that the assembly with the inner container of the water heating equipment is not limited by the space of the inner container under the condition of meeting the requirement of the pipeline flow, and the universal adaptability is strong. In addition, when the water flow velocity is large, the core tube 11 and the outer blind tube 12 can generate a proper amount of deformation due to certain elasticity, and the impact on the water flow is buffered, so that the whole breakage of the electricity-proof plug 10 can be effectively avoided, and the service life of the product is further prolonged.
Preferably, the outer blind pipe 12 and the core pipe 11 are both insulating silicone tubes made of a silica gel material, and the hardness of the insulating silicone tubes is 65-85 degrees. The electricity-proof plug 10 is moderate in hardness and elasticity, has good flexibility and bending freedom, and does not change the size of the inner hole of the core tube 11 and the section of the gap 101 when being bent, so that water flow can smoothly pass through the electricity-proof plug. In addition, the silica gel material is odorless and tasteless, is safer to use, has a simple forming process and lower raw material cost, and can effectively reduce the cost.
Further, referring to fig. 2, in the second embodiment of the electricity-proof plug 10 of the present invention, a water-retaining cover 13 is sleeved on the outer blind pipe 12, and one side of the water-retaining cover 13 facing the water distribution hole 120 is opened. Specifically, when the electricity-proof plug 10 is arranged at the water inlet of the hot water device, the outer blind pipe 12 can be sleeved with the water-retaining cover 13, the water-retaining cover 13 can be arranged to be a horn-shaped cover body flaring towards one side of the water distribution hole 120, the cold water sprayed from the water distribution hole 120 can change the water flow direction after flowing back to the water-retaining cover 13 through the water inlet of the hot water device, and the water can be further buffered and uniformly distributed through the water-retaining cover 13, so that the cold water is prevented from impacting hot water in the inner container of the hot water device too much, and the hot water output rate is ensured. Preferably, the water blocking cover 13 is made of an elastic material, for example, the water blocking cover 13 may be made of a rubber or silica gel material with certain elasticity, so as to further improve the buffering effect.
In addition, a first insulating gasket 123 is arranged on the periphery of the pipe orifice of the outer blind pipe 12, a second insulating gasket 113 is arranged on the periphery of the pipe orifice of the first end part 111, and the first insulating gasket 123 and the second insulating gasket 113 are connected in a laminated manner. Specifically, the opening of the outer blind pipe 12 may be turned to form a first insulating gasket 123, the opening of the first end 111 of the core pipe 11 may be turned to form a second insulating gasket 113, after the outer blind pipe 12 is sleeved on the core pipe 11, the first insulating gasket 123 and the second insulating gasket 113 are stacked, and then the first insulating gasket 123 and the second insulating gasket 113 are connected together to form an integrated insulating gasket through processes such as secondary vulcanization or adhesive bonding, etc. compared with the conventional electricity preventing plug 10 that requires additional fasteners and sealing members to connect and fix multiple layers of sleeves, the electricity preventing plug 10 of the present invention has a simpler and more reliable structure. In addition, when the electricity-proof plug 10 is communicated with the electric water heating equipment and an external pipeline, the first insulating gasket 123 and the second insulating gasket 113 can also play a role of isolating an electric insulating broken bridge, so that non-electric connection of the whole pipeline of the electric water heating equipment is realized, and the safety use performance is further improved.
Preferably, the outer blind pipe 12 and the core pipe 11 are both made of insulating rubber hoses made of insulating colloid materials, and correspondingly, the first insulating gasket 123 and the second insulating gasket 113 are both made of insulating rubber materials, and since the insulating gaskets have good sealing elasticity, when the electricity-proof plug 10 is installed, only the insulating standard pipe fitting needs to be adopted for fixing, other auxiliary sealing elements are not needed, the structure is simpler and more reliable, and the standardization and mass production of products are facilitated.
Further, the outer blind pipe 12 and the core pipe 11 are coaxially arranged, so that the design has the advantages that the gap between the outer blind pipe 12 and the core pipe 11 is consistent, the water outlet flow of each water distribution hole 120 is consistent, the water distribution is further buffered and uniform, the cold water is prevented from impacting hot water in the inner container too much, and the hot water output rate is ensured.
Further, in one embodiment, the inner circumference of the nozzle of the first end portion 111 is chamfered, which is beneficial to reduce the flow resistance of the inlet of the core tube 11 and avoid the insulation gasket from being deformed by extrusion during installation and use to block the core tube 11.
