[0040] like Figures 1-4As shown, this embodiment provides an anti-electric shock wall device, which includes a housing 100, a sleeve 200, and a foaming unit 300. One end of the housing 100 is provided with a main water outlet 110, and one end of the main water outlet 110 is integrally formed with a water outlet pipe 120. A first flow channel 121 is formed inside the water outlet pipe 120, and the first flow channel 121 is connected to the main water outlet 110. One end of the sleeve 200 is closed, and the other end is open. The sleeve 200 is detachably sleeved on the water outlet pipe 120. A second flow channel is formed between the outer wall of the sleeve 200 and the inner wall of the housing 100. A third flow channel is formed between the inner wall of the sleeve 200 and the outer wall of the water outlet pipe 120. The third flow channel is connected to the second flow channel and the first flow channel 121. The foaming unit 300 is detachably installed inside the housing 100, and the foaming outlet of the foaming unit 300 is connected to the inlet of the second flow channel.

[0041] The anti-electric shock wall device has an integrally formed outer casing 100 with a water outlet pipe 120. A sleeve 200 is installed between the water outlet pipe 120 and the outer casing 100. A second flow channel is formed between the outer wall of the sleeve 200 and the inner wall of the outer casing 100, and a third flow channel is formed between the inner wall of the sleeve 200 and the outer wall of the water outlet pipe. This allows liquid to flow sequentially through the third flow channel, the second flow channel, and the first flow channel 121, finally exiting through the main outlet 110, achieving an anti-electric shock effect. Simultaneously, the anti-electric shock wall device integrates a foaming unit 300 to generate sparkling water, meeting users' needs for sparkling water and increasing the device's functionality. Furthermore, the sleeve 200 and the foaming unit 300 are detachably installed within the outer casing 100, allowing for the selection of different parameters for the sleeve 200 and the foaming unit 300 to adapt to various usage needs, thus expanding the applicability of the anti-electric shock wall device.

[0042] Specifically, the bubbling unit 300 includes a venturi tube 310 and a hydrocyclone 320 disposed downstream of and connected to the venturi tube 310; one end of the hydrocyclone 320 away from the venturi tube 310 abuts against the end of the sleeve 200.

[0043] For example, the Venturi tube 310 includes a tube body 312, and the tube body 312 is provided with a plurality of spaced Venturi channels 313, which extend through the tube body 312. The water flow entering the anti-electric shock device first enters the Venturi channels 313, and then enters the cyclone separator 320 to be converted into sparkling water.

[0044] In this embodiment, the Venturi channel 313 includes a constricted section 314, a transition section 315, and a flared section 316 connected in sequence. The flared section 316 is positioned close to the hydrocyclone 320. Towards the hydrocyclone 320, the inner diameter of the constricted section 314 gradually decreases, while the inner diameter of the flared section 316 gradually increases. That is, the cross-sectional area through which water flows in the middle section of the Venturi tube 310 decreases. According to the Venturi principle, increased flow velocity leads to decreased pressure, reducing the solubility of gas in water, causing it to detach from the water and form nanoscale bubbles. The faster the flow velocity, the better the bubble formation effect. Optionally, the inner diameter of the transition section 315 remains unchanged.

[0045] Furthermore, the hydrocyclone 320 includes a cylinder 322 and a plurality of blades 323 disposed within the cylinder 322. The plurality of blades 323 are connected to the inner wall of the cylinder 322, and the plurality of blades 323 are spaced apart around the central axis of the cylinder 322, with a flow channel 324 formed between adjacent blades 323. The water flowing out of the venturi channel 313 then enters the flow channel 324. The swirling blades 323 of the hydrocyclone 320 break up the bubbles, so that bubble water can be formed at the bubble outlet after the liquid flows through the bubble-generating unit 300.

[0046] In summary, by incorporating the aeration unit 300, the cross-sectional area through which the water flows is reduced and the water flow path is lengthened, thereby increasing the resistance of the current flowing through the water circuit and improving the anti-electric shock effect of the anti-electric shock wall device. It is worth noting that the resistance of the anti-electric shock wall device is the sum of the resistance of the sleeve 200 and the outlet pipe 120, and the resistance of the venturi tube 310 and the hydrocyclone 320.

[0047] Preferably, in order to achieve the connection and positioning between the Venturi tube 310 and the hydrocyclone 320, the Venturi tube 310 is provided with a plurality of first connecting protrusions 311 at the end near the hydrocyclone 320, and the hydrocyclone 320 is provided with a plurality of second connecting protrusions 321 at the end near the Venturi tube 310. When the Venturi tube 310 and the hydrocyclone 320 are installed, the second connecting protrusions 321 can be positioned between two adjacent first connecting protrusions 311.

[0048] In this embodiment, the outer casing 100 is cylindrical. To facilitate the installation and disassembly of the anti-electric shock wall device, the outer wall of the outer casing 100 is provided with a flat groove 140. Operators can use tools such as wrenches to cooperate with the flat groove 140 to facilitate clamping and twisting during installation and disassembly, thereby realizing the installation and disassembly of the anti-electric shock wall device.

[0049] Optionally, there are multiple planar grooves 140, which are symmetrically arranged circumferentially along the outer wall of the housing 100. This improves the reliability of the clamping between the tool and the outer wall of the housing 100. It is understood that two planar grooves 140 symmetrically arranged circumferentially along the outer wall of the housing 100 form a group for simultaneous engagement with the tool. Multiple groups of planar grooves are arranged circumferentially along the outer wall of the housing 100 to facilitate engagement with the tool at different mounting angles.

[0050] Furthermore, to facilitate the installation of the anti-electric shock device, external threads 150 are provided on the outer wall of the main water outlet 110 and the outer wall at the end away from the main water outlet 110. By providing external threads 150, the anti-electric shock device can be integrated as a separate component into the outer casing of the display panel, adapting to the diversified functional needs of the electric water heater. Making the anti-electric shock device a movable module effectively saves space, facilitates the integration of multiple functions of the electric water heater, and improves aesthetics.

[0051] In this embodiment, a guide surface is provided at the connection point between the second flow channel and the third flow channel, and / or at the connection point between the third flow channel and the first flow channel 121. By providing a guide surface at the water flow bend, the water flow is guided, which helps to reduce the water flow resistance at the bend, thereby reducing the impact on the water output of the anti-electric shock wall device. While achieving anti-electric shock, the amount of water entering the anti-electric shock wall device is increased.

[0052] Specifically, the outer casing 100 has a main outlet 110 at one end extending away from the main outlet 110 to form an outlet pipe 120. The outer wall of the outlet pipe 120 and the inner wall of the outer casing 100 form an installation cavity, and the bottom of the installation cavity is provided with a first arc surface 130. That is, the first arc surface 130 serves as a guide surface at the connection position between the second flow channel and the third flow channel, and the first arc surface 130 is concave towards the main outlet 110.

[0053] Furthermore, the open end of the sleeve 200 is provided with a plurality of first abutment blocks 210, which are spaced apart circumferentially and abut against the inner wall of the outer shell 100. The first abutment blocks 210 are used to position the sleeve 200 relative to the outer shell 100 in the axial direction. It can be understood that the shape of the first abutment blocks 210 is adapted to the first arc surface 130 to ensure the reliability of the abutment. At the same time, the closed end of the sleeve 200 is provided with a plurality of second abutment blocks 220, which are spaced apart circumferentially and abut against the outlet end of the aerating unit 300. This is used to position the aerating unit 300 relative to the outer shell 100 in the axial direction and to provide a conductive space between the aerating outlet and the second flow channel.

[0054] In this embodiment, the outer wall of the sleeve 200 is provided with three or more ribs 230 along the circumferential direction. The ribs 230 extend axially along the sleeve 200 and abut against the inner wall of the outer shell 100 through the outer side wall of the ribs 230, thereby achieving radial positioning between the sleeve 200 and the outer shell 100. Exemplarily, the ribs 230, the first abutting block 210 and the second abutting block 220 are provided in a one-to-one correspondence; the ribs 230, the first abutting block 210 and the second abutting block 220 are integrally formed.

[0055] In addition, the outer wall of the outlet pipe 120 is provided with three or more first protrusions 122 along the circumferential direction. The first protrusions 122 extend along the axial direction of the outlet pipe 120 and abut against the inner wall of the sleeve 200, thereby achieving radial positioning between the pipe and the outlet pipe 120. Optionally, to achieve radial positioning between the sleeve 200 and the outlet pipe 120, three or more second protrusions can also be provided along the circumferential direction on the inner wall of the sleeve 200. The second protrusions extend along the axial direction of the sleeve 200 and abut against the outer wall of the outlet pipe 120.

[0056] Preferably, the aeration unit 300, the outer shell 100, the sleeve 200 and the water outlet pipe 120 are all coaxially arranged, which helps to ensure the uniformity of the circumferential width of each flow channel, thereby ensuring the uniformity of the water flow.

[0057] This embodiment also discloses an electric water heater, including the anti-electric shock wall device as described in any of the above embodiments. By incorporating the aforementioned anti-electric shock wall device, the electric water heater achieves better anti-electric shock performance and also provides aerated water; simultaneously, it has fewer components, higher integration, and is easier to assemble, thereby enhancing its market competitiveness.

[0058] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0059] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
