[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] See also Figure 1-4 The utility model provides a water bottle, including an inner liner 1, a lower water filter assembly 8 arranged at the bottom of the inner liner 1, a water pump 4 and a water outlet pipe 6. Specifically, the inner liner 1 includes a glass body 11 and a microcrystalline glass plate 12 arranged at the bottom of the glass body 11, and a water outlet hole is opened in the middle of the microcrystalline glass plate 12; the lower water filter assembly 8 includes a lower water inlet pipe 81 penetrating the water outlet hole, the water inlet end of the water pump 4 is connected and conducted with the lower water inlet pipe 81, and the water outlet end of the water pump 4 is connected and conducted with the water outlet pipe 6. Preferably, the lower water inlet pipe 81 is made of stainless steel.

[0037] Thus, under the action of the water pump 4, the water in the inner tank 1 can be pumped out and flow out through the lower water inlet pipe 81, the water pump 4 and the water outlet pipe 6 in sequence for drinking by the user.

[0038] In this embodiment, a sealing ring 7 is also included. The sealing ring 7 is sleeved at the connection between the lower water inlet pipe 81 and the water inlet end of the water pump 4 to form a waterproof seal.

[0039] Furthermore, the lower water filter assembly 8 also includes a filter screen 83 and a clamping ring 82. The filter screen 83 is made of metal and is arranged on the top of the lower water inlet pipe 81. The clamping ring 82 is also made of metal and is sleeved on the outer peripheral side of the lower water inlet pipe 81; specifically, the top of the lower water inlet pipe 81 is bent outward to form a first flange 811, and the filter screen 83 is riveted on the first flange 811. The lower water inlet pipe 81 is hung on the top of the water outlet hole through the filter screen 83 and is located inside the inner tank 1; the top of the clamping ring 82 is bent outward to form a second flange 821, and the clamping ring 82 is abutted against the bottom end of the water outlet hole through the second flange 821 and is located outside the inner tank.

[0040] The outer wall of the lower water inlet pipe 81 , the inner wall of the water outlet, the filter screen 83 and the clamping ring 82 enclose a glue groove 84 , and the glue groove 84 is filled with colloid to fix the lower water filter assembly 8 on the inner tank 1 .

[0041] The collar 82 is also provided with a bent portion 823 for grounding. Since the filter 83 and the collar 82 are both connected to the lower water inlet pipe 81, the filter 83 can be grounded by grounding the collar 82, thereby ensuring the safety of the user during use; in addition, since the collar 82 is located outside the inner tank 1 and is separated from the inner tank 1 by water, the grounding is safer and more reliable.

[0042] It should be noted that, in other embodiments, the lower water inlet pipe 81 can also be grounded (the connecting wire is directly welded to the outer wall of the lower water inlet pipe 81), thereby achieving grounding of the filter screen 83. At this time, the clamping ring 82 only serves to clamp and fix the lower water inlet pipe 81. Since there is no need for grounding, the clamping ring 82 can be made of plastic.

[0043] See also Figure 3-4 The bottom of the clamp ring 82 is provided with a plurality of claws 822, which abut against the outer wall of the lower water inlet pipe 81 to clamp the lower water inlet pipe 81. Therefore, by providing the claws 822 for clamping the lower water inlet pipe 81 on the clamp ring 82, and the clamp ring 82, the filter screen 83, the lower water inlet pipe and the inner tank 1 are all fixed by gluing, the assembly firmness of the lower water inlet pipe 81 can be ensured to prevent it from deviating and causing water leakage.

[0044] Furthermore, it also includes an NTC temperature probe 5 installed at the water inlet end of the water pump 4, and the NTC temperature probe 5 passes through the lower water inlet pipe 81 and the filter 83 and extends into the inner tank 1 to detect the water temperature in the inner tank 1. The filter 83 is provided with a through hole for the NTC temperature probe 5 to pass through.

[0045] In this embodiment, the NTC temperature probe 5 is fixed on the water pump 4 and is not connected to the filter 83 , so the NTC temperature probe 5 needs to be grounded separately to eliminate static electricity.

[0046] It should be noted that, in other embodiments, the NTC temperature probe 5 can also be riveted and fixed on the filter 83. In this case, the NTC temperature probe 5 and the filter 83 are an integrated structure. The grounding of the NTC temperature probe 5 can be achieved by grounding the filter 83, which is relatively simple and convenient and is not limited here.

[0047] Furthermore, it also includes a heating plate 2 disposed at the bottom of the microcrystalline glass plate 12, the heating plate 2 includes a heat transfer plate 21 and a heating pipe 22 disposed at the bottom of the heat transfer plate 21, the upper end surface of the heat transfer plate 21 is in contact with the bottom surface of the microcrystalline glass plate 12 to achieve heat transfer. Preferably, the heat transfer plate 21 is an aluminum plate.

[0048] In addition, it also includes a heat insulation cover 3 arranged below the heating plate 2. A fixing ring 9 is mounted on the glass body 11. The fixing ring 9 is provided with a plurality of jacks 91 for connecting with the heat insulation cover 3.

[0049] Therefore, by providing the heat insulation cover 3, the heat of the heating plate 2 can be prevented from being dissipated, thereby improving the heating efficiency of the inner tank 1, and at the same time, the heat can be prevented from being transferred to the outer shell of the water bottle to avoid scalding the user.

[0050] In summary, the utility model provides a water filter assembly 8 for a water bottle and a water bottle, which have the following beneficial effects:

[0051] (i) By sleeve-mounting a clamp ring 82 on the lower water inlet pipe 81 and grounding the clamp ring 82, the filter screen 83 can be grounded to ensure user safety; in addition, the clamp ring 82 is located outside the inner tank 1 and is separated from the water in the inner tank 1, making the grounding safer and more reliable.

[0052] (ii) A claw 822 for clamping the lower water inlet pipe 81 is provided on the clamp ring 82, and the clamp ring 82, the filter screen 83, the lower water inlet pipe 81 and the inner tank 1 are fixed by gluing. Such a configuration can ensure the assembly firmness of the lower water inlet pipe 81 and prevent it from deviating and causing water leakage.
