[0040] As described in the background art, drinking water devices include, but are not limited to, water dispensers and water purifiers, which are used to provide drinking water in people's daily lives. A drinking water device generally includes a housing, a water storage tank, a diversion pipe, a heating element and a water outlet. When in use, tap water or other drinking water to be heated is poured into the water storage tank, and then the water is pumped to the diversion pipe, and the heating element is used to heat the water in the diversion pipe, and the heated boiling water flows out from the water outlet for people to drink. The drinking water device is generally placed on a table or a lower tabletop. When people use it, if the water in the water cup is accidentally spilled onto the outer peripheral wall of the body, the water can be drained away through the guidance of the outer peripheral wall and the action of gravity. However, if the water is accidentally spilled onto the top, the water droplets will enter the interior of the drinking water device along the installation gap of the housing, thus posing a certain safety hazard to the internal electrical components such as the heating element and the heat conduction pipe.

[0041] To solve the above problems, refer to Figures 1 to 4 , the present application provides a drainage structure 10, which is disposed in a drinking water device and is used to drain the accumulated water falling on the body of the drinking water device. The drainage structure 10 specifically includes a body housing 11 and a drainage housing 12. The body housing 11 has a water collecting surface 1111, and a water collecting portion 1112 is provided on the water collecting surface 1111. The water collecting portion 1112 is used to collect the accumulated water falling on the water collecting surface 1111. The drainage housing 12 is fitted with the body housing 11, and a drainage surface 121 is provided on the side of the drainage housing 12 facing the body housing 11. The drainage surface 121 is used to drain the accumulated water collected in the water collecting portion 1112 to the outside of the body housing 11, so as to drain it to the outside of the body of the drinking water device, avoiding the accumulated water from falling into the body of the drinking water device after falling on the water collecting surface 1111. And during the water diversion process, the accumulated water flows all the way under the guidance of the wall surface of the drainage surface 121, avoiding the splashing of the accumulated water, so that the drainage structure 10 provided by the present application can achieve safe and effective drainage, thus ensuring the safe use of the drinking water device.

[0042] Specifically, refer to Figure 1, the fuselage housing 11 includes a busbar housing 111 and a mounting bracket 112. The busbar housing 111 is sleeved outside the mounting bracket 112. The water collecting surface 1111 and the busbar portion 1112 are both provided on the busbar housing. The mounting bracket 112 is arranged inside the busbar housing 111 for fixedly installing other structures of the drinking water equipment.

[0043] In one embodiment, refer to Figure 2 or Figure 4 , the busbar portion 1112 includes a busbar groove 11121. The busbar groove 11121 is in surface communication with the drainage surface 121. The busbar groove 11121 is used to collect the water falling on the water collecting surface 1111 into the busbar groove 11121. When water falls on the water collecting surface 1111, the accumulated water can flow into the busbar groove 11121 under the guidance of the water collecting surface 1111 and the groove wall of the busbar groove 11121, thus completing the water collection work of the busbar groove 11121 to facilitate the next water diversion work.

[0044] Furthermore, a guiding portion 1113 is also provided on the busbar housing 111 of the fuselage housing 11. The opposite ends of the guiding portion 1113 are respectively connected to the groove wall of the busbar groove 11121 and the drainage surface 121. After the accumulated water flows into the busbar groove 11121 under the guidance of the water collecting surface 1111 and the groove wall of the busbar groove 11121, the guiding portion 1113 can guide the accumulated water collected in the busbar groove 11121 to the drainage surface 121, so that through the drainage effect of the drainage surface 121, the water is discharged from the fuselage housing 11 through the drainage surface 121, preventing the accumulated water from entering the fuselage housing 11 and falling on the mounting bracket 112, thus causing a safety hazard of water ingress to the devices installed on the mounting bracket 112.

[0045] In one embodiment, refer to Figures 2 to 4 , the guiding portion 1113 includes a communication hole a penetrating through the busbar housing 111 and a guiding rib b provided on the hole wall of the communication hole a. The extending direction of the communication hole a intersects with the water collecting surface 1111 and the communication hole a is communicated with the busbar groove 11121. And one end of the guiding rib b is connected to the drainage housing 12. After the accumulated water flows into the busbar groove 11121 under the guidance of the water collecting surface 1111 and the groove wall of the busbar groove 11121, the accumulated water flows along the busbar groove 11121 into the communication hole a. Inside the communication hole a. Due to the setting of the guiding rib b on the hole wall of the communication hole a, the water flow entering the communication hole a is drained along the guiding rib b, so as to be drained to the drainage surface 121 and discharged. The accumulated water falling into the communication hole a flows under the guidance of the guiding rib b throughout the process, avoiding the splashing of the accumulated water, enabling the drainage structure 10 provided by the present application to achieve effective drainage, and thus ensuring the use safety of the drinking water equipment.

[0046] Preferably, in some of the embodiments, the confluence trough 11121 has a set slope, and the lowest point of the set slope is at the communication hole a, so as to better guide the accumulated water in the confluence trough 11121 into the communication hole a.

[0047] In some other embodiments, the guiding rib b also plays an assembling role, which is used to fixedly connect the fuselage shell 11 and the drainage shell 12. When the guiding rib b plays an assembling role, it can hold against the drainage shell 12, so as to control the assembling gap between the fuselage shell 11 and the drainage shell 12, avoid water leakage caused by too large an assembling gap, and thus damage the water diversion effect of the drainage surface 121.

[0048] In one of the embodiments, refer to Figure 1 and Figure 5 , the drainage structure 10 further includes a drainage base 13. The fuselage shell 11 and the drainage shell 12 are both arranged on the drainage base 13. A drainage port 131 is opened on the drainage base 13. The drainage port 131 allows the accumulated water drained by the drainage surface 121 to pass through, so as to drain the accumulated water converged in the confluence trough 11121 to the drainage base 13 through the drainage surface 121. The accumulated water is discharged from the drinking water device through the drainage port 131, and the accumulated water flows along the wall surface throughout the drainage process, thus avoiding the accumulated water splashing onto other structures inside the drinking water device, and making the use of the drinking water device safer.

[0049] In one of the embodiments, refer to Figure 1 , the drainage structure 10 further includes a top plate 14. The top plate 14 covers the water collecting surface 1111, and the top plate 14 has an L-shaped plug-in end 141. The L-shaped plug-in end 141 is plugged into the fuselage shell 11, so as to prevent the water from overflowing inside the drinking water device and then flowing into the fuselage along the assembling gap.

[0050] According to another aspect of the present application, there is provided a drinking water device as described in the above embodiments, including an electrical component 20 and the drainage structure 10 provided in any of the above embodiments. Through the drainage structure 10, the accumulated water falling on the fuselage shell 11 can be drained outside the fuselage shell 11, and thus drained outside the body of the drinking water device, avoiding the accumulated water falling into the water collecting surface 1111 and then entering the interior of the body of the drinking water device. And during the water diversion process, the accumulated water flows under the guidance of the wall surface of the drainage surface 121 throughout the process, avoiding the splashing of the accumulated water, so that the drainage structure 10 provided by the present application can achieve safe and effective drainage, thereby ensuring the use safety of the drinking water device.

[0051] Further, refer to Figure 6 , a first installation groove 1121 is provided on the side of the installation bracket 112 facing away from the drainage surface 121. The first installation groove 1121 is used to install the electrical component 20, so as to prevent the water splashed from being diverted from the fuselage shell 11 to the drainage shell 12 from dripping onto the electrical component 20, further ensuring the use safety.

[0052] In one embodiment, see Figure 4 and Figure 6 , a water outlet 30 is provided on the drainage housing 12, and a second mounting groove 1122 is also provided on the side of the mounting bracket 112 away from the drainage surface 121. A water inlet pipe, a heat pipe and a water outlet pipe (not shown in the figure) are provided in the second mounting groove 1122. The heat pipe is used to instantly heat the water in the water inlet pipe, and the water outlet pipe is connected to the water outlet 30, so that the water supply of the drinking water device can be completed and instant heating can be achieved. In addition, a water baffle 1123 is provided between the first mounting groove 1121 and the second mounting groove 1122 to prevent the leaked water from splashing onto the electrical component 20 after the water inlet pipe, the heat pipe and the water outlet pipe are accidentally broken. In this way, the leaked water can be effectively guided by the setting of the water baffle 1123 and discharged from the drinking water device from the drainage base 13 or other assembly gaps.

[0053] Specifically, when water enters from the water collecting surface 1111 of the fuselage shell 11, the water first flows along the collection groove 11121 set on the water collecting surface 1111. Part of the water can also be discharged from certain assembly gaps. Another part of the water is led by the collection groove 11121 to the connecting hole a, and under the guidance of the guide rib b, flows to the drainage surface 121 of the drainage shell 12, and under the guidance of the drainage surface 121, it is discharged from the drainage port 131 on the drainage base 13, thereby completing the discharge of accumulated water.

[0054] Specifically, when the internal pipes are broken and leak (such as the water outlet pipe, the water inlet pipe, etc.), water splashes, and because the water baffle 1123 is provided between the first mounting groove 1121 and the second mounting groove 1122, water is effectively prevented from dripping onto the electrical component 20. The splashed water is drained through the confluence groove 11121, the connecting hole a, the guide rib b and the drainage surface 121, and is directly discharged from the drinking water device through the assembly gap or the drainage base 13.

[0055] The drainage structure 10 and drinking water equipment provided by the present application have the following advantages:

[0056] (1) By providing a drainage structure 10 which specifically includes a fuselage housing 11 and a drainage housing 12, the fuselage housing 11 has a water collecting surface 1111, and a water collecting part 1112 is provided on the water collecting surface 1111. The water collecting part 1112 is used to collect the accumulated water falling on the water collecting surface 1111. The drainage housing 12 is fitted and assembled with the fuselage housing 11, and one side of the drainage housing 12 facing the fuselage housing 11 has a drainage surface 121. The drainage surface 121 is used to drain the accumulated water collected in the water collecting part 1112 outside the fuselage housing 11, so as to drain it outside the fuselage of the drinking water device, avoiding the accumulated water falling into the fuselage of the drinking water device after falling on the water collecting surface 1111. And during the water diversion process, the accumulated water flows under the guidance of the wall surface of the drainage surface 121 throughout the process, avoiding the splashing of the accumulated water, so that the drainage structure 10 provided by the present application can achieve safe and effective drainage, thus ensuring the use safety of the drinking water device;

[0057] (2) By providing a guiding part 1113 is also provided on the water collecting housing 111 of the fuselage housing 11. The two opposite ends of the guiding part 1113 are respectively connected to the groove wall of the water collecting groove 11121 and the drainage surface 121. When the accumulated water flows into the water collecting groove 11121 under the guidance of the water collecting surface 1111 and the groove wall of the water collecting groove 11121, the guiding part 1113 can guide the accumulated water collected in the water collecting groove 11121 onto the drainage surface 121, so that through the drainage function of the drainage surface 121, it is discharged from the fuselage housing 11 through the drainage surface 121, avoiding the accumulated water entering the fuselage housing 11 and falling on the mounting bracket 112, thus causing a safety hazard of water ingress to the devices mounted on the mounting bracket 112;

[0058] (3) By providing that the guiding part 1113 includes a communication hole a penetratingly opened on the water collecting housing 111 and a guiding rib b provided on the hole wall of the communication hole a. The extending direction of the communication hole a intersects with the water collecting surface 1111 and the communication hole a is communicated with the water collecting groove 11121, and one end of the guiding rib b is connected to the drainage housing 12. When the accumulated water flows into the water collecting groove 11121 under the guidance of the water collecting surface 1111 and the groove wall of the water collecting groove 11121, the accumulated water flows along the water collecting groove 11121 into the communication hole a. In the communication hole a, due to the setting of the guiding rib b on the hole wall of the communication hole a, the water flow entering the communication hole a is guided along the guiding rib b, and thus is guided onto the drainage surface 121 and discharged. The accumulated water falling into the communication hole a flows under the guidance of the guiding rib b throughout the process, avoiding the splashing of the accumulated water, so that the drainage structure 10 provided by the present application can achieve effective drainage, thus ensuring the use safety of the drinking water device;

[0059] (4) By providing a first installation groove 1121 and a second installation groove 1122 on the side of the installation bracket 112 facing away from the drainage surface 121, the first installation groove 1121 is used to install the electrical component 20, and a water inlet pipe, an instant heat pipe, and a water outlet pipe (not shown in the figure) are provided in the second installation groove 1122. The instant heat pipe is used to instantaneously heat the water in the water inlet pipe, and the water outlet pipe is communicated with the water outlet 30, so as to complete the water supply of the drinking water device and realize instant heating at the same time. Moreover, a water baffle 1123 is provided between the first installation groove 1121 and the second installation groove 1122 to prevent the water splashing onto the electrical component 20 after the water inlet pipe, the instant heat pipe, and the water outlet pipe are accidentally broken. Thus, through the setting of the water baffle 1123, the leaked water can be effectively guided and discharged from the drainage base 13 or other assembly gaps of the drinking water device.

[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0061] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
