[0038] Next, refer to Figures 1 - 7 Describe the direct drinking machine 100 according to an embodiment of the present invention.

[0039] As Figure 1 And Figure 3 Shown, the direct drinking machine 100 according to an embodiment of the present invention includes a housing 1, a water outlet nozzle 2, and a water receiving tray 3.

[0040] Specifically, as Figure 1 shown, the water outlet nozzle 2 is provided on the housing 1, and the water outlet nozzle 2 can be connected to the water path inside the housing 1. As Figure 5 shown, a filter element 4 can be provided inside the housing 1, and the water outlet nozzle 2 can be connected to the purified water outlet of the filter element 4. Of course, a water purification tank 5 can also be provided inside the housing 1. The inlet of the water purification tank 5 is connected to the purified water outlet of the filter element 4, and the outlet of the water purification tank 5 is connected to the water outlet nozzle 2. Of course, an instant heating system can also be provided between the outlet of the water purification tank 5 and the water outlet nozzle 2. The instant heating system includes an instant heating pipe 6. The purified water flowing out of the water purification tank 5 is heated by the instant heating pipe 6 and then flows out from the water outlet nozzle 2.

[0041] As Figure 3 and Figure 4 shown, a receiving groove 15 is provided on the outer bottom wall of the housing 1. The receiving groove 15 is adjacent to one end of the housing 1 where the water outlet nozzle 2 is provided, and the receiving groove 15 is open toward the side of the housing 1 where the water outlet nozzle 2 is provided. The water receiving box 3 includes a water receiving body 31 and a positioning protrusion 32 that cooperates with the receiving groove 15. As Figure 1 shown, the water receiving body 31 is opposite to the water outlet nozzle 2 and is located below the water outlet nozzle 2. As Figure 4 shown, the positioning protrusion 32 is provided on the side of the water receiving body 31 close to the housing 1, and the positioning protrusion 32 is located inside the receiving groove 15. When the water receiving box 3 is fixed to the housing 1, the water receiving body 31 is located directly below the water outlet nozzle 2, and the positioning protrusion 32 is located inside the receiving groove 15. When the water dispenser 100 is placed on a tabletop, the positioning protrusion 32 is located between the bottom wall of the receiving groove 15 and the tabletop, which can limit the displacement of the positioning protrusion 32 in the up and down direction and the displacement between both sides of the open mouth, thereby fixing the positioning protrusion 32 between the housing 1 and the tabletop. When disassembling the water receiving box 3, the housing 1 can be slightly lifted, and then the positioning protrusion 32 can be disassembled from the receiving groove 15, which is convenient for disassembling the water receiving box 3.

[0042] The direct drinking machine 100 according to an embodiment of the present invention is provided with a receiving groove 15 at one end of the outer bottom wall of the machine housing 1 close to the water outlet nozzle 2, and the side of the receiving groove 15 close to the machine housing 1 where the water outlet nozzle 2 is provided is open. The positioning protrusion 32 on the water receiving box 3 located below the water outlet nozzle 2 can be arranged in the receiving groove 15. When the direct drinking machine 100 is placed on a tabletop, the positioning protrusion 32 is located between the bottom wall of the receiving groove 15 and the tabletop, and can limit the displacement of the positioning protrusion 32 in the vertical direction and the displacement between both sides of the open mouth, so as to fix the positioning protrusion 32 between the machine housing 1 and the tabletop. When disassembling the water receiving box 3, the machine housing 1 can be slightly lifted, and then the positioning protrusion 32 can be disassembled from the receiving groove 15, which is convenient for disassembling the water receiving box 3. The direct drinking machine 100 of the present invention can simply and conveniently fix the water receiving box 3 around the machine housing 1, achieving the effects of convenient movement and reliable fixation, and there are no other redundant components, and the assembly is simple.

[0043] Further, a limiting groove 16 is provided on one of the side walls of the receiving groove 15 and the side walls of the positioning protrusion 32, and a limiting protrusion 33 cooperating with the limiting groove 16 is provided on the other of the side walls of the receiving groove 15 and the side walls of the positioning protrusion 32 to limit the positioning protrusion 32 from escaping from the open mouth of the receiving groove 15 facing the water outlet nozzle 2. Thus, the positioning protrusion 32 can be further limited, preventing the positioning protrusion 32 from escaping from the open mouth facing the water outlet nozzle 2, improving the reliability of the fixation of the positioning protrusion 32, and thereby improving the reliability of the fixation of the water receiving box 3.

[0044] For example, in Figure 3 and Figure 4 the illustrated example, limiting grooves 16 are provided on both opposite side walls of the receiving groove 15, and limiting protrusions 33 cooperating with the limiting grooves 16 are provided on both opposite side walls of the positioning protrusion 32. The cooperation between the limiting protrusion 33 and the limiting groove 16 can limit the movement of the water receiving box 3 in the direction away from the machine housing 1, thereby preventing the positioning protrusion 32 from escaping from the open mouth of the receiving groove 15 facing the water outlet nozzle 2, improving the reliability of the fixation of the positioning protrusion 32, and thereby improving the reliability of the fixation of the water receiving box 3. Among them, the lower end of the limiting groove 16 is open to facilitate the cooperation between the positioning protrusion 32 and the receiving groove 15.

[0045] When disassembling the water receiving box 3, slightly lift the end of the machine housing 1 where the water receiving box 3 is provided, then move the water receiving box 3 downward to remove it from the receiving groove 15, and then pour out the water in the water receiving box 3, or directly take out the water receiving box 3 with a little force; when installing the water receiving box 3, slightly lift the end of the machine housing 1 where the receiving groove 15 is provided, place the water receiving box 3 below the machine housing 1, then align the positioning protrusion 32 with the receiving groove 15, move the water receiving box 3 upward so that the positioning protrusion 32 is located in the receiving groove 15, the limiting protrusion 33 cooperates with the limiting groove 16, and finally lay the machine housing 1 flat to complete the installation of the water receiving box 3.

[0046] Of course, the present invention is not limited thereto. Limiting protrusions 33 may be provided on both opposite side walls of the receiving groove 15, and limiting grooves 16 cooperating with the limiting protrusions 33 may be provided on both opposite side walls of the positioning protrusion 32. The cooperation of the limiting protrusions 33 and the limiting grooves 16 can limit the movement of the water receiving box 3 in the direction away from the machine housing 1, thereby avoiding the open end of the receiving groove 15 in the positioning protrusion 32 from disengaging from the water outlet nozzle 2, improving the reliability of the fixation of the positioning protrusion 32, and thus improving the reliability of the fixation of the water receiving box 3. Among them, the upper end of the limiting groove 16 is open to facilitate the cooperation of the positioning protrusion 32 and the receiving groove 15. Of course, the lower end of the limiting groove 16 may also be open.

[0047] Optionally, as Figure 4 shown, in the direction from one end of the positioning protrusion 32 connected to the water receiving body 31 to the other end, the width of the water receiving body 31 gradually decreases, thereby facilitating the cooperation of the positioning protrusion 32 and the receiving groove 15.

[0048] In some embodiments of the present invention, as Figure 2 shown, the water receiving body 31 has a water receiving groove 311. A water receiving cover plate 312 is provided at the open end of the water receiving groove 311. The water receiving cover plate 312 seals the open end of the water receiving groove 311, and the water receiving cover plate 312 can be used to support a water receiving container such as a cup. When the user needs to receive water, the cup can be placed on the water receiving cover plate 312, and then the water outlet button 21 is pressed. The user can complete the operation with one hand, which is convenient for the user to use.

[0049] Furthermore, a water leakage hole 313 is provided on the water receiving cover plate 312. During the water receiving process, when water leaks out, the water can be drained into the water receiving groove 311 through the water leakage hole 313. When the water in the water receiving groove 311 is full, the water receiving groove 311 can be disassembled and emptied to avoid the leaked water droplets from falling onto the tabletop or the ground. Even further, there are multiple water leakage holes 313, and each water leakage hole 313 extends along the length direction of the water receiving body 31. The multiple water leakage holes 313 are spaced apart along the width direction of the water receiving body 31. This can improve the drainage speed and prevent water droplets from falling onto the ground or the tabletop.

[0050] As Figure 1 and Figure 5 shown, a water outlet button 21 is provided on the top wall of the water outlet nozzle 2. Among them, the water outlet button 21 can be a pure mechanical button. When the water outlet button 21 is pressed, the water outlet nozzle 2 is communicated with the internal water path, and water can flow out from the water outlet nozzle 2. Of course, the water outlet button 21 can also be a control button. The water outlet button 21 can be connected to the electronic control box 7 in the machine housing 1. A water pump 8 can be provided on the water path communicated with the water outlet nozzle 2, and the water pump 8 is connected to the electronic control box 7. When the water outlet button 21 is pressed, after the electronic control box 7 receives the signal of the water outlet button 21, it controls the water pump 8 to work, and the water outlet nozzle 2 discharges water.

[0051] In the present invention, when a user holds a cup in one hand and cannot press the water outlet button 21 with the other hand, by arranging the water outlet button 21 on the water outlet nozzle 2, the hand of the user holding the cup can directly reach the water outlet button 21 and press it, which is convenient for the user to use, avoids the situation where both hands must be used to receive water, and also avoids the situation of water leakage caused by the user pressing the water outlet button 21 first and then going to receive water.

[0052] In some embodiments of the present invention, the housing 1 is provided with a water inlet connected to a tap water source, and a filter element 4 is arranged inside the housing 1, and the water inlet of the filter element 4 is connected to the water inlet. This can avoid setting a raw water tank on the direct drinking machine 100, eliminating the process of repeatedly adding water and facilitating the use of the user. In addition, since the raw water tank is omitted, the overall size of the direct drinking machine 100 can be reduced, and the occupied area of the direct drinking machine 100 can be decreased.

[0053] Furthermore, the housing 1 is provided with a water outlet, and the waste water outlet of the filter element 4 is connected to the water outlet. For the filter element 4 that discharges waste water, the generated waste water can directly flow into the drainage channel through the water outlet on the housing 1, avoiding setting a waste water tank on the housing 1, eliminating the trouble of pouring waste water and facilitating the use of the user. In addition, since the raw water tank is omitted, the overall size of the direct drinking machine 100 can be reduced, and the occupied area of the direct drinking machine 100 can be decreased.

[0054] In the related art, most of the direct drinking machines 100 are equipped with a raw water tank. During use, it is necessary to add water to the raw water tank and pour out the waste water in the waste water tank, which is rather troublesome.

[0055] In some embodiments of the present invention, as Figure 1 shown, the housing 1 includes a base 11, a front shell 12, a rear shell 13 and a middle shell 14. Both the front shell 12 and the rear shell 13 are U-shaped, the openings of the front shell 12 and the rear shell 13 face each other and are sequentially connected to form a chamber. The bottoms of the front shell 12 and the rear shell 13 are connected to the base 11, and the tops of the front shell 12 and the rear shell 13 are connected to the middle shell 14. The water outlet nozzle 2 is arranged on the front shell 12, and the water receiving tray 3 is arranged on the front side of the front shell 12. Inside the housing 1, there are a water purification tank 5, an instant heating system, a filtration system, a water circuit board 9, and an electric control system, etc. The water treatment process is as Figure 8 shown, the booster pump 10, the water circuit board 9, and the solenoid valve 101 are fixed at the rear end of the middle shell 14, the filter element 4 is placed in the hollow cavity of the middle shell 14, the water purification tank 5 is fixed at the front end of the middle shell 14, the instant heating system is fixed on the side and bottom of the water purification tank 5, and the electric control system is installed in the electric control box 7 on the top of the water purification tank 5.

[0056] As Figure 8 shown, the specific water treatment process is that tap water enters from port a, is filtered by the filter element 4, waste water is discharged from port b, and drinking water is discharged from port c.

[0057] Of course, the clean water tank 5 can also be arranged outside the casing 1, and the water outlet nozzle 2 is communicated with the clean water tank 5, and the water in the clean water tank 5 can also be taken at any time.

[0058] In some embodiments of the present invention, when the water in the clean water tank 5 flows out from the water outlet nozzle 2 through the instant heating system, since there is a large amount of water vapor in the high-temperature water and it forms and diffuses irregularly, when the water vapor accumulates to a sufficient amount, it will burst, generating an irregularly directed force on the water column, causing the phenomena of the water column floating, scattering, and spraying steam.

[0059] As Figure 6 and Figure 7 shown, the water outlet nozzle 2 includes a housing 22 and a separator 23. The top wall of the housing 22 is provided with an inlet 221, and the bottom wall of the housing 22 is provided with an outlet 222. The inlet 221 can be communicated with the clean water tank 5 inside the casing 1. The separator 23 is arranged inside the housing 22. The outer peripheral wall of the separator 23 is spaced apart from the inner peripheral wall of the housing 22 to define a steam channel 225. The housing 22 is provided with an air outlet 223 communicated with the steam channel 225. The upper end of the separator 23 is spaced apart from the inner top wall of the housing 22 to enable the inlet 221 to be communicated with the steam channel 225. The separator 23 has a water flow channel 231. The upper end of the water flow channel 231 is opposite to and communicated with the inlet 221, and the lower end of the water flow channel 231 is opposite to and communicated with the outlet 222. Thus, the high-temperature water enters from the inlet 221. Inside the water outlet nozzle 2, the steam is separated from the water. The steam flows from the steam channel 225 to the air outlet 223, and the water flows out from the lower outlet 222, thereby separating the water and steam, avoiding the scattering and spraying of the water column, and ensuring smooth water outlet.

[0060] Optionally, as Figure 6 shown, the air outlet 223 is arranged at the lower end of the housing 22. This can increase the path length of the steam channel 225, which is beneficial to the separation of steam and water. When water enters the steam channel 225, it is convenient for the water to be discharged.

[0061] Optionally, as Figure 6 shown, the air outlet 223 extends in the vertical direction. Thus, it is beneficial for the steam to be discharged even from the inside of the water outlet nozzle 2.

[0062] Optionally, as Figure 6 shown, there are a plurality of air outlets 223, and the plurality of air outlets 223 are spaced apart in the circumferential direction of the housing 22. This is convenient for the steam in the steam channel 225 to be discharged.

[0063] Optionally, at least one flow channel 224 is provided on the outer shell 22. The flow channel 224 is spaced apart from the air outlet 223 in the circumferential direction of the outer shell 22, and the lower end of the flow channel 224 extends to the bottom wall of the outer shell 22. Among them, in the circumferential direction of the outer shell 22, the width of the flow channel 224 is greater than the width of the air outlet 223. This facilitates the discharge of a large amount of steam from the flow channel 224, and when the steam condenses into water droplets, it can flow out from the flow channel 224.

[0064] Furthermore, there are two flow channels 224, and the two flow channels 224 are symmetric about the central plane of the outer shell 22. This facilitates the discharge of a large amount of steam from the symmetric flow channels 224, and when the steam condenses into water droplets, it can flow out symmetrically from the flow channels 224.

[0065] Optionally, as Figure 7 shown, the lower end of the separator 23 is inserted into the outlet 222 and the lower end of the separator 23 extends beyond the lower end of the outer shell 22. This facilitates the separation of water and steam and prevents the water from recombining with the steam.

[0066] Optionally, as Figure 7 shown, the cross-sectional area of the water flow channel 231 is greater than the cross-sectional area of the inlet 221, and the projection of the inlet 221 on the horizontal plane is located within the projection of the end of the water flow channel 231 opposite to the inlet 221 on the horizontal plane. This can ensure that water can smoothly enter the water flow channel 231 and prevent water from entering the steam channel 225 together with the steam.

[0067] In some embodiments of the present invention, the outer shell 22 includes a first cylindrical section 226 and a first tapered section 227. In the direction from top to bottom, the cross-sectional area of the first tapered section 227 gradually decreases, and the upper end of the first tapered section 227 is connected to the lower end of the first cylindrical section 226. The separator 23 includes a second cylindrical section 232 and a second tapered section 233. In the direction from top to bottom, the cross-sectional area of the second tapered section 233 gradually decreases, and the upper end of the second tapered section 233 is connected to the lower end of the second cylindrical section 232. This can make the water flow more concentrated, prevent the water from scattering, and is beneficial to the separation of water vapor.

[0068] Among them, as Figure 7 shown, the first tapered section 227 is a conical section, and the side wall of the cross-section of the first tapered section 227 is a straight line. The second tapered section 233 is a stepped section, and the side wall of the cross-section of the second tapered section 233 is a stepped line.

[0069] Optionally, at least one of the inner peripheral wall of the outer shell 22 and the outer peripheral wall of the spacer 23 is provided with a first support rib to space apart the inner peripheral wall of the outer shell 22 and the outer peripheral wall of the spacer 23, thereby defining a steam channel 225. In addition, at least one of the inner top wall of the outer shell 22 and the top wall of the spacer 23 is provided with a second support rib to space apart the inner top wall of the outer shell 22 and the top wall of the spacer 23, so that the inlet 221 communicates with the steam channel 225.

[0070] Further, the outer shell 22 includes an outer shell body and a cover body. The outer shell body is annular, and the cover body is provided at the top end of the outer shell body to cover the top open mouth of the outer shell body. The cover body is provided with an inlet 221, and the bottom open mouth of the outer shell body is configured as an outlet 222. The spacer is disposed in the chamber defined by the outer shell body and the cover body.
