DETAILED DESCRIPTION

[0022] In order to make clearer the purpose, the solution of the technique and the advantages of the present disclosure, the embodiments of the present disclosure will be described in detail below together with the accompanying drawings. Petition 870250062375, dated 07 / 21 / 2025, page 13 / 38 6 / 16 It should be noted that the modalities of the present disclosure and the characteristics of the modalities may be arbitrarily combined with each other if there is no conflict.

[0023] As shown in Figures 1 to 4, the heating cup assembly provided by the embodiment of the present application includes: a cup body 100 with a first water outlet port; and a switching valve 200 with a second water inlet port and a plurality of second water outlet ports 211. The second water inlet port is in communication with the first water outlet port. The switching valve 200 is configured to allow the second water inlet port to be in communication with any of the pluralities of second water outlet ports 211.

[0024] In the heating cup assembly, the first water outlet port of the cup body 100 is in communication with the second water inlet port of the switching valve 200. The switching valve 200 can allow the second water inlet port to be in communication with any of the various second water outlet ports 211, and the water in the cup body 100 flows to the switching valve 200 through the first water outlet port, so as to discharge water from any of the various second water outlet ports 211. The user can freely select any of the various water outlet ports 211 to be in communication with an overhead spray shower or a hand shower or a hot and cold water tap, which provides better practicality.

[0025] In some forms, the plurality of second water outlet ports 211 are two second ports Petition 870250062375, dated 07 / 21 / 2025, p. 14 / 38 7 / 16 of water outlet 211, either of the two second water outlet ports 211 is in communication with the overhead shower or the hand shower or the hot and cold water tap, and the other of the two second water outlet ports 211 is also in communication with the overhead shower or the hand shower or the hot and cold water tap.

[0026] It is possible that either of the two second water outlet ports 211 is in communication with an overhead shower, and the other of the two second water outlet ports 211 is in communication with the other overhead shower, i.e., either of the two overhead showers discharges water. Alternatively, it is possible that one of the two second water outlet ports 211 is in communication with the hand shower, and the other of the two second water outlet ports 211 is in communication with the overhead shower, i.e., either of the hand showers and the overhead shower discharge water. Alternatively, it is possible that either of the two second water outlet ports 211 is in communication with the hand shower, and the other of the two second water outlet ports 211 is in communication with the other hand shower, i.e., either of the two hand showers discharges water.All of the above items can achieve the objective of the present application, and their objective does not deviate from the design idea of ​​the present disclosure; therefore, they will not be repeated here, and all of them should fall within the scope of protection of the present application.

[0027] Of course, it is also possible that the plurality of second water outlet ports 211 are three second ones Petition 870250062375, dated 07 / 21 / 2025, page 15 / 38 8 / 16 water outlet ports 211 or four secondary water outlet ports 211 or five secondary water outlet ports 211, etc. All of the above items can achieve the purpose of the present application, and their purpose does not deviate from the design idea of ​​the present disclosure, therefore, they will not be repeated here, and all of them must fall within the scope of protection of the present application.

[0028] In some examples, as shown in Figures 2 to 4, the switching valve 200 includes: a valve support 210 integrated with the cup body 100 and with a second water inlet port and two second water outlet ports 211; and a valve core 220 movably mounted in the valve support 210. The valve core 220 is configured to allow the second water inlet port to be in communication with either of the two second water outlet ports 211 by switching at least one of the positions and angles (i.e., the second water inlet port may be in communication with one of the two second water outlet ports 211, or the second water inlet port may be in communication with the other of the two second water outlet ports 211).

[0029] The valve support 210 and the cup body 100 are of integrated structure, for example, the valve support 210 and the cup body 100 are manufactured integrally by an injection molding process. This solution can effectively reduce the manufacturing difficulty and manufacturing cost of the switching valve 200 compared to manufacturing the valve support 210 separately.

[0030] It is possible that the core of valve 220 is rotatably mounted in the support of valve 210, so that Petition 870250062375, dated 07 / 21 / 2025, page 16 / 38 9 / 16 A position (i.e., angle) of the valve core 220 is changed by rotating the valve core 220, the second water inlet port can be in communication with either of the two second water outlet ports 211, and the solution is a relatively mature technology. Alternatively, it is possible that the valve core 220 can be movably mounted on the valve support 210, so that the position of the valve core 220 is changed by moving the valve core 220, the second water inlet port can be in communication with either of the two second water outlet ports 211, and this solution is also a relatively mature technology. All of the above items can achieve the objective of the present application, and their objective does not deviate from the design idea of ​​the present disclosure, therefore, they will not be repeated here, and all of them must fall within the scope of protection of this application.

[0031] In some examples, as shown in Figures 2-4, the cup body 100 includes a cup body perimeter wall 130 and a cup body bottom wall 140. A perimeter of the cup body bottom wall 140 is connected to a lower end of the cup body perimeter wall 130, and the valve support 210 is located on the lower wall of the cup body 140. An upper part of the valve core 220 is located on the valve support 210, and a lower part of the valve core 220 is located below the valve support 210 and the lower wall of the cup body 140. When the valve core 220 is rotatably mounted on the valve support 210, the valve core 220 is actuated to rotate (to change the posture of the valve core 220) by connecting a motor to the lower end of the Petition 870250062375, dated 07 / 21 / 2025, page 17 / 38 10 / 16 valve core 220 below the cup body 100, and the motor is easier to arrange.

[0032] In some examples, as shown in Figure 2, the cup body 100 additionally includes a water outlet pipe 120 and a heating pipe 300. The water outlet pipe 120 is provided vertically within the peripheral wall of the cup body 130 and located above the valve support 210, the second water inlet port is located at the top of the valve support 210, the water outlet pipe 120 is located above the valve support 210, the first water outlet port is located at a lower end of the water outlet pipe 120, and the first water outlet port is in communication with the second water inlet port. The heating tube 300 includes a spiral section 310 sheathed outside the water outlet tube 120, an upper end of the water outlet tube 120 has a water inlet port 121, and the water inlet port 121 is located above the spiral section 310.In this solution, the water outlet pipe 120 is a vertical pipe.

[0033] Since the hot water in the cup body 100 will float, the temperature of the water in the upper part of the cup body 100 is higher than the temperature of the water in the lower part of the cup body 100. The water in the upper part of the cup body 100 enters the water outlet pipe 120 from the water inlet port of the water outlet pipe 120 and then flows along the water outlet pipe 120 to the first water outlet port (i.e., flows downwards). In this process, the water in the water outlet pipe 120 is heated again by the spiral section 310. Therefore, the temperature of the water discharged from the second water outlet port 211 is higher and the efficiency Petition 870250062375, dated 07 / 21 / 2025, page 18 / 38 11 / 16 of the heating of the spiral section 310 is greater.

[0034] It is possible that the water outlet pipe 120 and the valve support 210 are supplied as an integrated structure, for example, the water outlet pipe 120 is manufactured integrally with the valve support 210 and the cup body 100 by injection molding the valve support 210 and the cup body 100. Alternatively, it is possible that the water outlet pipe 120 and the valve support 210 are supplied as a split structure, for example, the water outlet pipe 120 and the valve support 210 are connected by threads or similar. All of the above items may achieve the objective of the present application, and their objective does not deviate from the design idea of ​​the present disclosure, therefore, they will not be repeated here, and all of them must fall within the scope of protection of this application.

[0035] In some examples, as shown in Figures 1 and 2, the heating cup assembly additionally includes a cover body 400 mounted on an upper end of the peripheral wall of the cup body 130, and the heating tube 300 additionally includes a mounting section 320. The mounting section 320 penetrates and is fixed to the cover body 400. An upper end of the mounting section 320 is located above the cover body 400 and is configured to be electrically connected to a control unit, and a lower end of the mounting section 320 is connected to the spiral section 310.

[0036] The cover body 400 is hermetically and securely mounted to the upper end of the peripheral wall of the cup body 130, and the mounting section Petition 870250062375, dated 07 / 21 / 2025, page 19 / 38 12 / 16 320 penetrates hermetically and is fixed to the cover body 400, so that the heating tube 300 and the cup body 100 are hermetically assembled together through the cover body 400. This solution is simple in process and easy to operate.

[0037] In some embodiments, as shown in Figure 1, the cover body 400 is a heat-conducting member equipped with a temperature control device. The temperature control device acquires a temperature from the heat-conducting member and switches off the heating tube 300 when the temperature of the heat-conducting member reaches a defined temperature limit.

[0038] The temperature control device is provided as a temperature limiter 500. The hot water in the upper part of the cup body 100 comes into contact with the heat-conducting member, and the temperature limiter 500 detects the heat from the heat-conducting member. When the temperature of the heat-conducting member reaches the set temperature limit (and the temperature of the hot water in the upper part of the cup body 100 reaches the set temperature limit), the heating tube 300 is switched off (for example, the heating tube 300 is connected in series with the temperature limiter 500), and the heating tube 300 stops heating the water in the cup body 100 at that time.

[0039] In some embodiments, as shown in Figures 2 to 4, the cup body 100 also has a first water inlet port 110, the first water inlet port 110 and two second water outlet ports 211 are all located on an outer lower part of the peripheral wall of the cup body 130. The two second ports of Petition 870250062375, dated 07 / 21 / 2025, page 20 / 38 13 / 16 water outlets 211 are spaced at 180 degrees in a circumferential direction from the peripheral wall of the cup body 130, and the first water inlet port 110 is located above the second two water outlet ports 211, so that the cold water supplied to the cup body 100 from the first water inlet port 110 can contact the spiral section 310 over a larger area during the upward process. Therefore, the spiral section 310 has a better heating effect on the cold water supplied from the first water inlet port 110 to the cup body 100 (i.e., the heating efficiency of the heating tube 300 is higher).

[0040] In some examples, as shown in Figures 2 and 3, a geometric axis of the first water inlet port 110 is offset from a geometric axis of the peripheral wall of the cup body 130, and at that moment, the first water inlet port 110 is obliquely above the two second water outlet ports 211, so that the cold water supplied to the cup body 100 from the first water inlet port 110 spirals up along the peripheral wall of the cup body 100, which can further increase the contact area with the spiral section 310 and can also improve the consistency of the water temperature at the same height in the cup body 100. Therefore, the hot water exiting the second water outlet port 211 has a higher temperature and less temperature difference.

[0041] In some embodiments, as shown in Figures 2 and 3, the geometric axis of the first water inlet port 110 and the geometric axis of the peripheral wall of the cup body 130 are located in different but perpendicular planes, and a port wall of the first Petition 870250062375, dated 07 / 21 / 2025, p. 21 / 38 14 / 16 water inlet port 110 is tangent to the peripheral wall of the cup body 130, which ensures that a greater quantity of cold water supplied from the first water inlet port 110 to the cup body 100 spirals up along the peripheral wall of the cup body 100.

[0042] An instant heating device (not shown in the figures) provided by an embodiment of the present application includes the heating cup assembly described in any of the embodiments above.

[0043] The instant heating device has all the advantages of the heating suction cup assembly supplied in any of the above modalities, which will not be repeated here.

[0044] The instant heating device includes instant water heaters, instant drinking fountains and smart toilets.

[0045] In short, in the heating cup assembly provided by the embodiment of this application, the first water outlet port of the cup body is in communication with the second water inlet port of the switching valve. The switching valve can allow the second water inlet port to be in communication with any of the pluralities of secondary water outlet ports, and the water in the cup body flows to the switching valve through the first water outlet port, so as to discharge water from any of the pluralities of secondary water outlet ports. The user can freely select any of the various secondary water outlet ports to be in communication with the overhead sprinkler shower, hand shower, or hot and cold water tap, which provides better Petition 870250062375, dated 07 / 21 / 2025, p. 22 / 38 15 / 16 practicality.
