As shown in fig. 1 to 11, the present application provides a waterproof case, which includes a first case 200 and a second case 300 connected to each other, a first installation cavity is formed in the first case 200, a second installation cavity is formed in the second case 300, and in an installation state, the first case 200 is at the back, and the second case 300 is assembled at the front to form a waterproof case as a whole.

The first installation inner cavity and the second installation inner cavity are connected in an opposite direction to form an inner cavity for packaging components of the water heater 100, and because the first shell 200 and the second shell 300 are connected in a connecting process, a connecting gap 110 exists, when a user uses the water heater, water with short time and large flow is sprayed at the connecting position of the first shell 200 and the second shell 300, and the hidden danger that water flows into the inner cavity from the connecting gap 110 exists.

As shown in fig. 2 and 3, in order to prevent the above problem, an overflow part 210 is formed at the top of the first case 200 or the second case 300; the overflow part 210 comprises a plurality of overflow grooves 211 formed at the top of the first shell 200 or the second shell 300, adjacent overflow grooves 211 are separated by a groove plate 212, the design of the plurality of overflow grooves 211 can better prevent external water from entering the overflow grooves 211 and then flowing in a large range, the minimum range of the external water can be ensured to flow in the overflow grooves 211 through the blocking effect of the groove plate 212, and the external water can be quickly conveyed to the outside of the waterproof shell through the overflow grooves 211 where the external water is located.

The first housing 200 and the second housing 300 are mounted in such a manner that the first housing 200 is partially fitted over the second housing 300, or the second housing 300 is partially fitted over the first housing 200, so that overlapping portions overlapping each other are formed between the first housing 200 and the second housing 300.

In a connected state, when the connection portion of the first housing 200 is positioned at the inner side of the second housing 300, that is, the second housing 300 is overlapped at the outer side of the first housing 200, the overflow groove 211 is formed on the first housing 200, whereas the overflow groove 211 is formed on the second housing 300.

Then, in the process that external water enters the internal cavity through the connection gap 110 between the first housing 200 and the second housing 300, the external water first enters the overflow groove 211, and the overflow groove 211 outputs the external water to the outside of the waterproof housing, so as to prevent the external water from entering the internal cavity and affecting the normal operation of the components located in the installation cavity.

Each overflow groove 211 is communicated with at least one overflow hole 213, the overflow hole 213 is arranged at the lowest position of the overflow groove 211, and the overflow hole 213 outputs the water entering the overflow groove 211 to the outer side of the waterproof shell to prevent the water from gathering in the overflow groove 211.

As shown in fig. 10 and 11, the bottom of each overflow groove 211 is formed with an inclined surface 214 inclined outward from the connecting center of the first housing 200 and the second housing 300, and the inclined surface 214 gradually decreases along the connecting gap 110 toward the overflow hole 213, so as to ensure that all water in the overflow groove 211 is output from the overflow hole 213.

In the circulation process of external water, the external water generally cannot gather on the side surface of the waterproof shell due to self gravity; however, the impact of a large flow rate for a short time also risks the penetration of external water from the side connection slit 110, thereby affecting the waterproof performance.

In order to solve the above problem, as shown in fig. 2 to 6, waterproof portions 220 for blocking external water from entering into a waterproof case from a joint of the first case 200 and the second case 300 are formed at both sidewalls of the first case 200 and/or the second case 300.

The waterproof part 220 includes a first waterproof layer 221, the first waterproof layer 221 is formed at the inner side of the first case 200 and/or the second case, the first waterproof layer 221 blocks water flow, and when external water enters the inner chamber from the side connection gap 110, the first waterproof layer 221 blocks and intercepts the external water.

A first waterproof groove 222 is formed between the first waterproof layer 221 and the first casing 200 and/or the second casing, and a part of the external water blocked by the first waterproof layer 221 is transported to the bottom along the inside of the first waterproof groove 222.

When the first waterproof layer 221 is not enough to block the infiltration of water, a second waterproof layer 223 is further disposed at the inner side thereof, a second waterproof groove 224 is formed between the second waterproof layer 223 and the first waterproof layer 221, so as to further isolate the external water outside the inner chamber, and the infiltrated external water flows to the bottom through the first waterproof groove 222 or the second waterproof groove 224.

In order to achieve the water retaining effect, when the first waterproof layer 221 and the second waterproof layer 223 are disposed on the first shell 200, the outer edge of the first waterproof layer 221 protrudes out of the sidewall of the first shell 200 and extends towards the second shell 300, and the outer edge of the second waterproof layer 223 protrudes out of the outer edge of the first waterproof layer 221 and extends towards the second shell 300, so as to ensure that the first waterproof layer 221 and the second waterproof layer 223 exceed the connection gap 110 between the first shell 200 and the second shell 300, thereby achieving the water retaining purpose.

Likewise, when the first waterproof layer 221 and the second waterproof layer 223 are provided on the second case 300, the outer edge of the first waterproof layer 221 protrudes beyond the sidewall of the second case 300 to extend toward the first case 200, and the outer edge of the second waterproof layer 223 protrudes beyond the outer edge of the first waterproof layer 221 to extend toward the first case 200.

As shown in fig. 8, a plurality of drain holes 230 are formed at the bottom of the first case 200 and/or the second case, the drain holes 230 communicate the internal chamber with the outside, and the external water in the first waterproof groove 222 and the second waterproof groove 224 is transferred to the outside through the drain holes 230 at the bottom, thereby preventing the external water from being accumulated in the installation chamber.

The present application also proposes a water heater 100, which comprises a heating element 400, a water inlet pipe 500 and a water outlet pipe 600 arranged in the waterproof housing.

As shown in fig. 7, in some embodiments of the present application, for convenience of installation, the heating element 400, the water inlet pipe 500 and the water outlet pipe 600 are all pre-fixed in the first installation cavity, the overflow part 210 is located at the top 201 of the first casing, the waterproof part 220 is disposed on the side wall 202 of the first casing, the water discharging hole 230 is disposed at the bottom 203 of the first casing, and the second casing 300 is covered outside the first casing 200.

When a large amount of water is collected in the water heater 100 for a short time, the water penetrates into the connection gap 110 between the first and second housings 200 and 300, and the overflow groove 211 guides the deep external water from the overflow hole 213 to the outside, so that the collected water has a flowing direction, and the collected water is guided to the outside of the machine.

The double-deck waterproof design of side makes product waterproof performance promote greatly, outside water from the infiltration of side gap back, because the dual waterproof design of first waterproof layer 221 and second waterproof layer 223, outside water circulates the bottom of waterproof shell finally from first waterproof groove 222 and second waterproof groove 224, finally discharges the outside from wash port 230 for waterproof performance improves greatly, has protected the normal work of inside components and parts, satisfies water heater 100's waterproof demand.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention, and therefore, the scope of the present invention shall be subject to the claims.
