[0033] Reference Figs. 1 to 3 For the water replenishing and exhausting device special for the gas module stove, the cylinder body 100 is provided with a containing cavity 110, the upper side of the containing cavity 110 is provided with a water inlet hole 120, the lower part of the containing cavity 110 is provided with a water outlet hole 130, and the upper part of the containing cavity 110 is provided with a gas exchange hole 140; the tap water pipe joint 200 is arranged at the upper end of the cylinder body 100, and the inner cavity of the tap water pipe joint 200 is communicated with the containing cavity 110 through the water inlet hole 120; the water stop floating ball 300 is located in the containing cavity 110 and is opposite to the water inlet hole 120 in the up-down direction, and the water stop floating ball 300 can move in the up-down direction to block or open the water inlet hole 120; the first water outlet pipe 400 is arranged on the cylinder body 100, and one end of the first water outlet pipe 400 is communicated with the water outlet hole 130.

[0034] The tap water pipe joint 200 is connected with the tap water pipe, the tap water is opened by the water pressure to open the water stop floating ball 300, the water is filled into the containing cavity 110 of the cylinder body 100, the water in the containing cavity 110 is entered into the first water outlet pipe 400 through the water outlet hole 130 and replenishes the circulating water path, the excess air in the cylinder body 100 and the circulating water path is exhausted through the gas exchange hole 140, then the liquid level in the cylinder body 100 rises, the water stop floating ball 300 blocks the water inlet hole 120 of the containing cavity 110, and the water in the containing cavity 110 is prevented from overflowing from the exhaust hole; the water replenishing and exhausting device special for the gas module stove can replenish water by using the tap water pressure, so that the size of the water replenishing and exhausting device can be reduced, and the water replenishing and exhausting device does not need to be installed at a high position.

[0035] It should be understood that when the water stop floating ball 300 blocks the water inlet hole 120, the liquid level in the containing cavity 110 should be lower than the gas exchange hole 140, so that the risk of the water in the containing cavity 110 overflowing from the gas exchange hole 140 is avoided, and the gas exchange capacity of the gas exchange hole 140 is maintained.

[0036] Specifically, the water stop floating ball 300 can be made of a material with a density less than water or a hollow structure, for example, a plastic floating ball or a rubber floating ball, and the water stop floating ball 300 can be circular, cylindrical or other shapes, which are not limited here.

[0037] In the embodiment, the air vent hole 140 is located on the side wall of the accommodating cavity 110, and the hole axis of the air vent hole 140 is in the horizontal direction. Without the air vent hole 140 and the water inlet hole 120 being located on the upper wall of the cylinder body 100, the cross section of the cylinder body 100 can be made smaller, which is beneficial to the compactness of the structure of the cylinder body 100 and the relative convenience of the processing and manufacturing.

[0038] It can be understood that in other embodiments, the air vent hole 140 can also be located on the upper wall of the cylinder body 100, and the hole axis of the air vent hole 140 can be arranged in the vertical direction.

[0039] In the embodiment, the upper side of the water stop floating ball 300 is provided with a guide rod 500, the guide rod 500 is arranged in the up-down direction and penetrates the water inlet hole 120, and the cross-sectional area of the guide rod 500 is smaller than that of the water inlet hole 120. The guide rod 500 is arranged to penetrate the water inlet hole 120, so that when the liquid level in the accommodating cavity 110 rises and falls, the water stop floating ball 300 can always be opposite to the water inlet hole 120 in the up-down direction, thereby enabling the water stop floating ball 300 to stably block the water inlet hole 120 when the liquid level in the accommodating cavity 110 rises, and reducing the risk of misalignment between the water stop floating ball 300 and the water inlet hole 120. The water inlet hole 120 itself forms a guide function, the cross-sectional area of the guide rod 500 is smaller than that of the water inlet hole 120, and the gap between the water inlet hole 120 and the guide rod 500 can allow water flow to pass through to inject tap water into the accommodating cavity 110, thereby simplifying the structure of the water replenishing and air exhausting device and eliminating the need for additional structures to guide the movement of the water stop floating ball 300.

[0040] It can be imagined that in other embodiments, a guide strip in the up-down direction can also be arranged on the inner wall of the cylinder body, and the water stop floating ball 300 is provided with a guide groove, the guide strip and the guide groove are in sliding cooperation, and the water stop floating ball 300 is limited to keep opposite to the water inlet hole 120 in the up-down direction.

[0041] In the embodiment, the cylinder body 100 is a cylinder, the cross section of the accommodating cavity 110 perpendicular to the up-down direction is circular, the cross section of the water stop floating ball 300 perpendicular to the up-down direction is circular, and the diameter of the accommodating cavity 110 is greater than that of the water stop floating ball 300. Along the direction perpendicular to the up-down direction, the diameter of the water stop floating ball 300 is smaller than that of the accommodating cavity 110, so that there is a gap between the water stop floating ball 300 and the side wall of the accommodating cavity 110, which can allow tap water entering from the water inlet hole 120 to flow to the lower part of the accommodating cavity 110 through the water stop floating ball 300 to enter the water outlet hole 130, and facilitate the movement of the water stop floating ball 300 along the up-down direction with the liquid level.

[0042] In the embodiment, the water stop floating ball 300 is in the shape of a cylinder, the central axis of the water stop floating ball 300 is coaxially arranged with the central axis of the cylinder body 100, the structure is relatively stable, the use effect is good, and the diameter of the cylinder body 100 can be relatively small.

By arranging the second water outlet pipe 600, tap water can directly replenish another circulating water path through the second water outlet pipe 600, meeting different use requirements.

[0047] Specifically, in the present embodiment, the gas module stove has two circulating water paths. One of the circulating water paths is connected to the first water outlet pipe 400, and the other of the circulating water paths is connected to the second water outlet pipe 600.

[0048] In an embodiment, a water inlet valve 700 is further included, and the water inlet valve 700 is arranged at the water inlet end of the water pipe joint 200. By arranging the water inlet valve 700, when water is not needed to be supplied to the water replenishing and exhausting device, or when the gas module stove is maintained, the tap water can no longer enter the water pipe joint 200 by closing the water inlet valve 700, facilitating the actual use of the water replenishing and exhausting device.

[0049] Specifically, the water inlet valve 700 can be a ball valve, a gate valve, or a stop valve, and those skilled in the art can select according to actual needs.
