DETAILED DESCRIPTION

[0026] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-6As shown, a bottle joint, the bottle joint 1 includes an annular cover 101 and a plug 102, the outer ring side wall of the annular cover 101 is provided with strip ribs 9 evenly distributed in an annular shape, the inner ring of the annular cover 101 is provided with threads, which is convenient for rotating the annular cover 101 on the bottle mouth of the mineral water bottle 22, the outer side wall of the plug 102 is provided with an annular groove 19, and a joint sealing ring 12 is installed in the annular groove 19, the plug 102 is used to be inserted into the docking part of the water heater, the joint sealing ring 12 can ensure the sealing of the plug-in joint, the plug 102 is connected to the bottom of the annular cover 101, and a plurality of evenly distributed second reinforcing ribs 15 are installed between the plug 102 and the annular cover 101 to improve the overall structural strength of the bottle joint 1.

[0028] A water valve groove 2 and an air valve groove 3 are provided at one end of the annular cover 101 close to the plug 102. The water valve groove 2 and the air valve groove 3 are both located inside the annular cover 101, and a water outlet valve 4 and an air inlet valve 5 are installed at the water valve groove 2 and the air valve groove 3, respectively. A water drop channel 13 connected with the water valve groove 2 is provided in the plug 102, so that water passing through the water outlet valve 4 can be conveniently introduced into the plug 102 via the water drop channel 13. A first reinforcing rib 14 is installed between the water drop channel 13 and the inner wall of the plug 102 to improve the structural stability. An air inlet 6 is provided on the side wall of the plug 102 close to one end of the annular cover 101, and the air inlet 6 is connected with the air valve groove 3, so that outside air can be added to the mineral water bottle 22 via the air inlet 6 and the air inlet valve 5 to ensure that the water in the bottle can smoothly enter the water dispenser body 21.

[0029] One end of the water outlet valve 4 is an arc surface structure 401, which protrudes away from the plug 102, and is provided with a cutout portion 402, which has a first abutting portion 4021 and a second abutting portion 4022 arranged opposite to each other, and has a first state and a second state, when the cutout portion 402 is in the first state, the first abutting portion 4021 and the second abutting portion 4022 are in contact and sealed, when the cutout portion 402 is in the second state, there is a gap 4023 between at least part of the first abutting portion 4021 and the second abutting portion 4022, and the inner cavity of the annular cover 101 is in communication with the inner cavity of the plug 102. The highest point position of the cutout portion 402 when in the second state is lower than the highest point position of the cutout portion 402 when in the first state;

[0030] The arc surface structure 401 cooperates with the cutout portion 402 to well resist water pressure. When water is not needed, the cutout portion 402 is closed under the water pressure and surface tension. When used in conjunction with the water dispenser body, the mineral water bottle 22 is placed above the water dispenser body 21 through the bottle joint 1. When there is more water in the mineral water bottle 22, the water outlet valve 4 needs to withstand a certain water pressure. The present application adopts a water outlet valve 4 with an arc surface structure 401. The arc surface structure 401 faces the direction of the water flow and can well resist a certain water pressure. It opens under the suction of the pump of the water dispenser body 21. This is different from the background technology in which a duckbill valve is used as the water outlet valve, because the water outlet head of the duckbill valve faces the same direction as the water flow, and it is easy to leak under the action of water pressure. That is, when the water dispenser body 21 is in the standby state, the cutout portion 402 is in the first state, at which time the cutout portion 402 can withstand the water pressure of the mineral water bottle 22 and keep the first abutting portion 4021 and the second abutting portion 4022 in contact and sealed; when the water dispenser body 21 is in the working state, under the suction of the pump of the water dispenser body 21, the cutout portion 402 is in the second state, at which time the cutout portion 402 is deformed, and a gap 4023 is formed between at least part of the first abutting portion 4021 and the second abutting portion 4022, and at this time the water in the mineral water bottle 22 flows into the water dispenser body 21 through the gap 4023 for heating treatment.

[0031] The water outlet valve 4 includes a base 403 and a transition seat 404, the arc surface structure 401 is located above the transition seat 404, the outer diameter of the base 403 is larger than the inner diameter of the water valve groove 2, so the base 403 is pressed downward by the valve cover 7; and at least a part of the transition seat 404 is located in the water valve groove 2, so that the arc surface structure 401 is located above the water valve groove 2. When the arc surface structure 401 is opened under the suction of the pump, the first abutting portion 4021 and the second abutting portion 4022 will deform toward the circumferential side. Therefore, the arc surface structure 401 is located above the water valve groove 2, avoiding the restriction of the inner wall of the water valve groove 2 on the arc surface structure 401 and affecting the deformation of the arc surface structure 401, thereby avoiding affecting the normal water outlet of the arc surface structure 401 when it is opened under the suction of the pump.

[0032] The air inlet valve 5 includes a duckbill valve, but is not limited to the duckbill valve. The air inlet valve 5 can also use an arc surface valve with the same structure as the water outlet valve 4. This valve can resist the water pressure well and will not leak under the action of the water pressure in the bottle. A valve cover 7 for pressing the water outlet valve 4 and the air inlet valve 5 is installed in the annular cover 101, which is convenient for pressing and positioning the water outlet valve 4 and the air inlet valve 5 installed in the annular cover 101, making the assembly of the entire bottle joint 1 simpler and more convenient, which is conducive to improving the overall assembly efficiency. The valve cover 7 includes an annular pressing plate 701, and the center of the annular pressing plate 701 is provided with a valve cover that is aligned with the water outlet valve 4. Corresponding to the first pressure hole 16, a second pressure hole 17 corresponding to the air inlet valve 5 is provided near the edge of the annular pressure plate 701, and an assembly ring 8 is pressed and arranged on the outer side of the annular pressure plate 701 to facilitate the fixing of the valve cover 7. The assembly ring 8 is fixedly installed on the side of the annular cover 101 away from the plug 102, and a protrusion 11 is fixedly installed on the inner ring of the assembly ring 8. A notch 18 which coincides with the protrusion 11 is provided on the annular pressure plate 701 to play a positioning role and facilitate assembly. A bottle sealing ring 10 is installed between the outer ring of the assembly ring 8 and the inner ring of the annular cover 101 to ensure the sealing after the annular cover 101 is connected to the bottle mouth.

[0033] When the air intake valve 5 uses a duckbill valve, in this embodiment, the valve cover 7 also includes a barrel cover 702, which is located on the side of the annular pressure plate 701 away from the plug 102. The barrel cover 702 is integral with or fixed to the annular pressure plate 701. The barrel cover 702 has a limiting channel 20 connected to the second pressure hole 17. The duckbill end of the duckbill valve will extend upward into the limiting channel 20. Covering it with the barrel cover 702 will make the installation of the duckbill valve more stable.

[0034] It is understandable that the mineral water bottle 22 may also be replaced by other containers, which are cooperatively connected with the annular cover 101 .

[0035] The working principle of the utility model is as follows: the water outlet valve 4 and the air inlet valve 5 are respectively installed in the water valve groove 2 and the air valve groove 3, and then the valve cover 7 is assembled in the annular cover 102, and the water outlet valve 4 and the air inlet valve 5 are pressed and positioned by the valve cover 7 to complete the assembly of the bottle joint 1, and the annular cover 101 of the bottle joint 1 is installed at the bottle mouth of the mineral water bottle 22, and then the plug 102 of the bottle joint 1 is inserted into the water dispenser body 21, and the arc surface structure 401 of the water outlet valve 4 cooperates with the cutout portion 402 to well resist the water pressure. When water is not needed, the cutout is made to Part 402 is closed, and the water pump in the water dispenser body 21 is started. The water outlet valve 4 is opened under the suction of the water pump, so that the water in the mineral water bottle 22 can enter the water dispenser body 21. The reduction of water in the water bottle will generate negative pressure, and the outside air is replenished into the mineral water bottle 22 through the air inlet 6 and the air inlet valve 5, ensuring that the water in the bottle can smoothly enter the water dispenser body 21. The water pump stops working, and the water outlet valve 4 is closed when there is no suction of the water pump, so that the water in the mineral water bottle 22 does not enter the water dispenser body 21. At this time, no negative pressure is generated inside the mineral water bottle 22, and the air inlet valve 5 will also be closed.

[0036] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
