In the present invention, the terms "first" and "second" do not denote any particular quantity or order, but are merely used to distinguish names.

In one embodiment, referring to fig. 1, fig. 2, fig. 3 and fig. 9, an anti-electric plug 100 includes: and a dielectric 110. More than two sub-chambers 130 are provided in the electricity-proof body 110. The two or more divided chambers 130 are sequentially communicated with each other. The electricity-proof body 110 is provided with a water inlet 1121 and a water outlet 1111. The water inlet 1121 communicates with one of the split chambers 130. The water outlet 1111 communicates with another sub-chamber 130. The water inlet 1121, the more than two separate cavities 130 and the water outlet 1111 sequentially form a flow guide channel, and the water inlet 1121 and the water outlet 1111 are respectively used for being communicated with an external water source and the water tank 200. The water outlet direction at the water outlet 1111 is inclined relative to the axial direction of the electricity-proof body 110 and is deviated to the end of the electricity-proof body 110 on which the water inlet 1121 is arranged.

In the electricity-proof plug 100, more than two component cavities 130 are arranged in the electricity-proof body 110, and the water inlet 1121, the more than two component cavities 130 and the water outlet 1111 sequentially form a flow guide channel. When water enters from the water inlet 1121, the water flows through the two or more sub-chambers 130 along the diversion channels, and flows out of the water outlet 1111 and into the water tank 200. Because water loops through more than two sub-cavities 130 when flowing along the diversion channel, the water flow path is effectively prolonged, the effective damping length of water resistance is increased, the leakage current value can be reduced to a more effective safety range, and the running of hot water equipment is ensured to be safer. Meanwhile, the water outlet direction at the water outlet 1111 inclines relative to the axial direction of the electricity-proof body 110 and deviates to the end of the electricity-proof body 110 with the water inlet 1121, so when the electricity-proof plug 100 is mounted on the water tank 200, the flowing water does not directly impact the hot water in the water tank 200, but flows along the direction back to the water tank 200, and then is blocked by the inner wall of the water tank 200 or the connecting assembly 300 to slowly return to the hot water in the water tank 200, thus effectively slowing down the flow rate of the water entering the water tank 200, reducing the impact of the flowing water on the hot water in the water tank 200, enabling the water to stably enter the hot water in the water tank 200, avoiding disturbing the thermal field in the water tank 200, and being beneficial to improving the hot water output rate. In addition, compared with the traditional electricity-proof structure, the electricity-proof plug 100 of the embodiment has the characteristics of simple and reliable structure, safe and reliable electricity utilization, strong universality adaptability and the like.

It should be noted that, when the electricity-proof plug 100 is installed on the water tank 200, the water inlet 1121 is located outside the water tank 200, so as to be convenient for connecting to an external water source; the water outlet 1111 has two states: firstly, the water outlet 1111 extends into the water tank 200, and at the moment, the water flowing out of the water outlet 1111 flows to the inner wall of the water tank 200 and is blocked by the inner wall of the water tank 200 to slowly return to the hot water in the water tank 200; secondly, the water outlet 1111 does not extend into the water tank 200, that is, the water outlet 1111 is still in the connection assembly 300, and at this time, the water flowing out of the water outlet 1111 flows into the connection assembly 300 and is blocked by the inner wall of the connection assembly 300 to slowly return to the hot water in the water tank 200. The water flowing out of the water outlet 1111 is unheated and has a temperature lower than that of the hot water in the water tank 200.

Alternatively, the outlet direction at the water outlet 1111 is inclined relative to the axial direction of the electricity-proof body 110 and is biased towards the end of the electricity-proof body 110 where the water inlet 1121 is formed, and the implementation manner may be: an inclined flow guide structure is arranged at the water outlet 1111 and guides the direction of water flow through the inclined flow guide structure, so that the flowing water cannot directly impact hot water in the water tank 200; secondly, the opening direction of the water outlet 1111 is inclined and faces the water inlet 1121, so that the water flowing out does not directly impact the hot water in the water tank 200. For easy understanding of the water outlet direction of the present embodiment, taking fig. 3 as an example, the water outlet direction at the water outlet 1111 is S in fig. 3₁The indicated direction.

Optionally, the electricity-proof body 110 is made of a colloid insulating material such as silica gel; alternatively, it may be an insulating material such as plastic or resin; or, the insulating fiber reinforced material is added into the insulating material.

Further, referring to fig. 3, the water outlet 1111 is formed at an axial direction of the anti-electric device 110 relative to the anti-electric device 110, and an opening of the water outlet 1111 faces an end of the anti-electric device 110 having the water inlet 1121. Therefore, in the present embodiment, the water outlet 1111 is inclined toward the water inlet 1121, so that the water flowing out of the water outlet 1111 does not directly impact the hot water in the water tank 200. Simultaneously, set up the opening orientation slope of delivery port 1111, also have certain barrier effect to the speed of rivers, avoid flowing out water from delivery port 1111 and flow the hot field in the upset water tank 200 at the excessive speed to effectively avoid the hot water in the water tank 200 to cool down because of stirring fast, so, further improve hot-water outlet rate of hot-water heating equipment.

Further, referring to fig. 3, an anti-cracking hole 1112 is formed on the anti-cracking body 110, and the anti-cracking hole 1112 is communicated with an end of the water outlet 1111. Since the impact of water acts on the inner wall of the water outlet 1111 when the water flow is discharged from the water outlet 1111, a large amount of internal stress is concentrated at the end of the water outlet 1111, and the end of the water outlet 1111 is easily torn along the length of the water outlet 1111 as the usage time increases. Therefore, in the embodiment, the anti-cracking hole 1112 communicated with the end of the water outlet 1111 is arranged on the electricity-proof body 110, and the internal stress at two ends of the water outlet 1111 is released through the anti-cracking hole 1112, so that the distribution of power on the electricity-proof body 110 is improved, the structural strength of the electricity-proof body 110 is improved, and the end of the water outlet 1111 is effectively prevented from being torn. Specifically, in this embodiment, there are two anti-cracking holes 1112, and the two anti-cracking holes 1112 are respectively and correspondingly communicated with two ends of the water outlet 1111. Meanwhile, the crack prevention hole 1112 is a circular hole. In order to facilitate understanding of the length direction of the water outlet 1111 of the present embodiment, taking fig. 1 as an example, the length direction of the water outlet 1111 is S in fig. 1₂The indicated direction.

In one embodiment, referring to fig. 1, there are more than two water outlets 1111. More than two delivery ports 1111 intervals set up on the anticreep body 110, so, the impact force of effective dispersion rivers to delivery port 1111 department reduces the water pressure of delivery port 1111 department for the level steadily gets into in the water tank 200.

In one embodiment, referring to fig. 4, it should be noted that fig. 4 does not show the specific structure of the inclined water outlet 1111. A partition structure 120 is provided in the electricity preventing body 110. The partition structure 120 divides the interior of the electricity-proof body 110 into two or more divided cavities 130. The partition structure 120 is provided with a serial hole 121, and two adjacent divided cavities 130 are communicated through the serial hole 121. In this way, a stable multi-cavity structure is formed in the electricity-proof body 110 by the partition structure 120, so that water can stably flow through each component cavity 130 along the diversion channel. In this embodiment, the separation structure 120 and the electricity-proof body 110 are integrated, so that the whole structure of the electricity-proof plug 100 is more stable, and the water leakage between the split cavity 130 and the split cavity 130 caused by a gap between the separation structure 120 and the electricity-proof body 110 in the using process is avoided, thereby preventing the electricity-proof effect of the electricity-proof plug 100 from failing.

Alternatively, the specific shape of the partition structure 120 is not limited in this embodiment, and it is only necessary to divide the interior of the electricity-proof body 110 into two or more compartments. For example, when the partition structure 120 has a shape of a letter, a herringbone, a cross, a Chinese character 'mi', etc., the electricity-proof body 110 has 2-, 3-, 4-, 5-and other divided cavities 130 therein.

Further, referring to fig. 5, 6 and 7, the number of the serial holes 121 is two or more. Two adjacent serial holes 121 are staggered on the partition structure 120. Therefore, the two adjacent series holes 121 are arranged in a staggered manner, so that water entering one separation cavity through one series hole 121 in the two adjacent series holes 121 cannot be discharged from the other series hole 121 at once, a diversion channel is in a zigzag state, the path of the water in the electricity-proof body 110 is effectively prolonged, the effective damping length of the water resistor is further increased, and the safety performance of the water heating device is further improved. In the present embodiment, in two adjacent serial holes 121, one of the serial holes 121 is disposed at one end of the partition structure 120, and the other serial hole 121 is disposed at the other end of the partition structure 120. Thus, the effective damping length of the water resistance is greatly improved.

In one embodiment, referring to fig. 5, 6 and 7, the partition structure 120 includes a first partition 122, a second partition 123, a third partition 124 and a fourth partition 125. The split cavity 130 is divided into a first split cavity 131, a second split cavity 132, a third split cavity 133, and a fourth split cavity 134. The water inlet 1121 communicates with the first body chamber 131. The water outlet 1111 communicates with the fourth sub-chamber 134. The first, second, third and

fourth dividers

122, 123, 124 and 125 divide the interior of the dielectric body 110 into a first, second, third and

fourth chambers

131, 132, 133 and 134, respectively. The first separator 122, the second separator 123, and the third separator 124 are provided with serial holes 121. Therefore, when water is introduced into the water inlet 1121, the water passes through the first sub-chamber 131, the serial hole 121, the second sub-chamber 132, the serial hole 121, the third sub-chamber 133, the serial hole 121, the fourth sub-chamber 134 and the water outlet 1111 in sequence, so that the effective length of the water resistor is increased, and the electricity-proof effect of the water heating device is improved.

Further, referring to fig. 5, 6 and 7, the serial holes 121 of the first separator 122 and the serial holes 121 of the second separator 123 are disposed to be offset from each other, and the serial holes 121 of the second separator 123 and the serial holes 121 of the third separator 124 are disposed to be offset from each other. Therefore, the formed flow guide channel is in a zigzag state, and the effective length of the water resistance is further improved. In this embodiment, the serial hole 121 of the first partition 122 is located at an end of the first partition 122 away from the water inlet 1121; the serial hole 121 of the second partition 123 is located at one end of the second partition 123 near the water inlet 1121; the serial hole 121 of the third partition 124 is located at an end of the third partition 124 remote from the water inlet 1121. Therefore, the leakage current value can be reduced to be within 2mA by the electricity-proof plug 100 of the embodiment, so that the water resistance of the electricity-proof body 110 can automatically attenuate the leaked mains supply voltage and current to be within the safety index which can be borne by the human body under the condition that the electric water heater, the hot water tank or the water pipeline is leaked and the grounding is also invalid, and a basic reliable electricity protection system is provided for users on the water source.

In one embodiment, referring to fig. 1, the electricity-proof body 110 includes an electricity-proof blind pipe 111 and a gasket 112. A gasket 112 covers the open end of the blind electricity-proof pipe 111. A split cavity 130 is arranged in the electricity-proof blind pipe 111. The water inlet 1121 is provided on the gasket 112. The water outlet 1111 is arranged on the electricity-proof blind pipe 111. Thus, the electricity-proof body 110 is designed to be the electricity-proof blind pipe 111 and the gasket 112, so that a multi-cavity structure is more easily formed in the electricity-proof body 110, and water can flow more smoothly in the electricity-proof body 110. Meanwhile, one end of the electricity-proof blind pipe 111 is conveniently sealed through the gasket 112, so that only the water inlet 1111 is reserved at one end of the electricity-proof blind pipe 111. In addition, during the installation of the electricity-proof body 110, when the electricity-proof blind pipe 111 is inserted into the connecting pipe 310, the gasket 112 seals the opening of the connecting pipe 310, so as to form the water-tight and electricity-isolating functions.

Specifically, the electricity-proof blind pipe 111 and the gasket 112 are integrated, which is not only beneficial to simplifying the production process of the electricity-proof body 110, but also beneficial to improving the overall structural strength of the electricity-proof body 110.

In one embodiment, referring to fig. 1, fig. 2, fig. 3 and fig. 8, a water heating apparatus includes a water tank 200 and an anti-electricity plug 100 in any of the above embodiments. The electricity preventing body 110 is installed on the water tank 200. The water inlet 1121 communicates with the inside of the water tank 200. The water outlet 1111 is used for communicating with an external water source.

The above water heating apparatus adopts the above electricity-proof plug 100, and the electricity-proof body 110 is provided with two or more component cavities 130 communicated in sequence, so that the water inlet 1121, the two or more component cavities 130 and the water outlet 1111 form a flow guide channel in sequence. When water enters from the water inlet 1121, the water flows through the two or more sub-chambers 130 along the diversion channels, and flows out of the water outlet 1111 and into the water tank 200. Because water loops through more than two sub-cavities 130 when flowing along the diversion channel, the water flow path is effectively prolonged, the effective damping length of water resistance is increased, the leakage current value can be reduced to a more effective safety range, and the running of hot water equipment is ensured to be safer. Meanwhile, the water outlet direction at the water outlet 1111 inclines relative to the axial direction of the electricity-proof body 110 and deviates to the end of the electricity-proof body 110 with the water inlet 1121, so when the electricity-proof plug 100 is mounted on the water tank 200, the flowing water does not directly impact the hot water in the water tank 200, but flows along the direction back to the water tank 200, and then is blocked by the inner wall of the water tank 200 or the connecting assembly 300 to slowly return to the hot water in the water tank 200, thus effectively slowing down the flow rate of the water entering the water tank 200, reducing the impact of the flowing water on the hot water in the water tank 200, enabling the water to stably enter the hot water in the water tank 200, avoiding disturbing the thermal field in the water tank 200, and being beneficial to improving the hot water output rate.

Further, referring to fig. 9, the water heating apparatus further includes a connection assembly 300. The electricity preventing body 110 is installed in the connection assembly 300, and the electricity preventing body 110 is respectively used for being connected with the water tank 200 and an external water source through the connection assembly 300. Therefore, the water flowing out of the electricity-proof body 110 cannot directly impact the hot water in the water tank 200, but flows into the connecting component 300 first and returns to the hot water in the water tank 200 under the action of the inner wall of the connecting component 300, so that the impact force of the water on the hot water in the water tank 200 is greatly weakened, the stability of a thermal field in the water tank 200 is effectively ensured, and the hot water output rate is further improved. Meanwhile, the installation operation of the electricity preventing body 110 on the water heating apparatus is also facilitated through the connection assembly 300.

Further, referring to fig. 9, the connection assembly 300 includes a connection pipe 310 and a connection pipe 320 sleeved on the connection pipe 310. The connection pipe 310 is connected to the water tank 200, and the connection pipe 310 communicates with the water tank 200. The connecting pipe 320 is used for connecting with an external water source, the electricity-proof body 110 is sleeved in the connecting pipe 310, and the end of the electricity-proof body 110 is in sealing fit with one end of the connecting pipe 310 close to the connecting pipe 320.
