The invention is described in further detail below with reference to the following detailed description and accompanying drawings:

the first embodiment:

as shown in fig. 1 to fig. 3, the present embodiment provides a heating water tank including a water tank mechanism 100 and an expansion mechanism 200, which are as follows:

as shown in fig. 1 and 2, in the present embodiment, the tank mechanism 100 includes a tank assembly 120 having a water containing chamber therein, and a water outlet pipe assembly 110 and a water inlet pipe assembly communicating with the water containing chamber. The water outlet pipe assembly 110 is provided with a water outlet channel 111 for discharging water. The water outlet channel 111 comprises a first water outlet section 1111, a second water outlet section 1112 and a third water outlet section 1113 which are sequentially communicated, wherein the first water outlet section 1111 is located at the upstream of the second water outlet section 1112, the second water outlet section 1112 is located at the upstream of the third water outlet section 1113, the caliber of the first water outlet section 1111 is smaller than that of the second water outlet section 1112, and the caliber of the second water outlet section 1112 is smaller than that of the third water outlet section 1113. Wherein, the diameter of the first water outlet section 1111 is 1.4mm, the diameter of the second water outlet section 1112 is 2.5mm, and the diameter of the third water outlet section 1113 is 4 mm.

As shown in fig. 2 and 3, in the present embodiment, the expansion mechanism 200 is disposed on the top of the housing assembly 120, the expansion mechanism 200 includes a housing assembly 220 including an internal expansion chamber 221, an exhaust port 210 communicating with the expansion chamber 221, a float pipe 240 having a movable passage 241, and a float 230 located in the movable passage 241, the float pipe 240 communicating with the exhaust port 210 and the expansion chamber 221, respectively. The float ball pipe 240 is a vertically arranged pipeline, and a vertical strip-shaped opening is arranged on the peripheral surface of the float ball pipe 240 and is communicated with the movable channel 241 and the expansion cavity 221. It should be noted that the expansion chamber 221 is connected to the first outlet section 1111 and the second outlet section 1112 through a pipe.

In specific operation, after the water in the water containing cavity is heated, the outlet of the outlet pipe assembly 110 is in a closed state, so that the expansion water generated by temperature rise flows into the expansion cavity 221 through the outlet pipe assembly 110. In addition, since the exhaust port 210 communicates with the atmosphere, the expansion water can smoothly flow into the expansion chamber 221. With the inflow of the expansion water, the float ball 230 can move upward along the movable passage 241 under the action of the buoyancy, and finally the float ball 230 ascends to the highest position to block the air outlet 210. Therefore, in the heating water tank of the present embodiment, the water in the tank assembly 120 does not flow out of the expansion mechanism 200.

After the water in the water containing cavity is heated, the water is discharged normally through the water outlet pipe assembly 110, because the water from the water containing cavity enters the third water outlet section 1113, the second water outlet section 1112 and the first water outlet section 1111, which are smaller in diameter, in sequence, the speed of the water passing through the water outlet channel 111 is increased, the pressure at the position where the expansion mechanism 200 is communicated with the water outlet channel 111 is reduced to generate negative pressure, and the water in the expansion cavity 221 is sucked back to the water outlet pipe assembly 110. So that the expansion water heated at the next use can be stored in the expansion mechanism 200 again, ensuring the normal use of the expansion mechanism 200.

In the heating water tank of the embodiment, the expansion mechanism 200 of the heating water tank is communicated with the outside through the structure of the floating ball tube 240 and the floating ball 230, so that the expansion water can smoothly enter the expansion mechanism 200, and the floating ball 230 smoothly floats. Meanwhile, when the floating ball 230 reaches the top end, the air outlet 210 can be blocked, so that water cannot flow out of the expansion mechanism 200 to the outside, and the floating ball pipe 240 provided with the movable channel 241 can preset the floating track of the floating ball 230, so that the working reliability of the floating ball is improved. In addition, when the heating water tank normally discharges water, the water in the expansion mechanism 200 can be sucked away, the next working of the expansion mechanism 200 is ensured, and the problem that the expansion mechanism 200 cannot normally work or fails due to the fact that the water in the expansion mechanism 200 is not completely drained is solved.

In addition, it should be noted that, in another embodiment, the diameters of the first water outlet section 1111, the second water outlet section 1112 and the third water outlet section 1113 may be other values within 1mm to 10mm according to the actual water outlet amount and the parameter requirement of the expansion chamber 221, and will not be described herein again. In addition, in another embodiment, first water outlet section 1111, second water outlet section 1112 and third water outlet section 1113 may be configured as channels with continuously changing diameters, and first water outlet section 1111, second water outlet section 1112 and third water outlet section 1113 are only artificially divided into three sections, and are not limited to the structure of water outlet channel 111.

Second embodiment:

as shown in fig. 4, in the present embodiment, the heating tank also includes a tank mechanism 100 and an expansion mechanism 200. The structure of the water tank mechanism 100 is the same as that of the first embodiment, and is not described again here.

The expansion mechanism 200 includes a housing assembly 220 with an internal expansion cavity 221, an exhaust port 210 communicated with the expansion cavity 221, and a deformable membrane 250 separating the expansion cavity 221 into an upper chamber and a lower chamber, wherein the deformable membrane 250 is attached to the bottom wall of the lower chamber, the exhaust port 210 is communicated with the upper chamber, the lower chamber is communicated with the water outlet channel 111, and the deformable membrane 250 is an omega-shaped geometric body made of rubber.

In specific operation, after the water in the water containing cavity is heated, since the outlet of the outlet pipe assembly 110 is in a closed state, the expansion water generated by temperature rise flows into the lower chamber of the expansion cavity 221 through the outlet pipe assembly 110. In addition, since the exhaust port 210 is communicated with the atmosphere, the inflation water can smoothly flow into the lower chamber, and the deformation film 250 is forced to be deformed upward as the inflation water flows in.

When the water in the water containing cavity is heated and the water is discharged normally through the water outlet pipe assembly 110, the pressure at the position where the expansion mechanism 200 is communicated with the water outlet channel 111 is reduced to generate negative pressure, so that the water in the lower chamber is sucked back to the water outlet pipe assembly 110. So that the expansion water generated by heating can be stored in the expansion mechanism 200 again at the next use, and the normal use of the expansion mechanism 200 is ensured. It should be noted that the omega-shaped deformable membrane 250 also generates a restoring force after deformation, thereby further assisting in draining water from the expansion chamber 221 back to the outlet tube assembly 110.

Through the above scheme of the embodiment, when the heating water tank of the present application is discharged, the water in the expansion mechanism 200 can be discharged, so that the expansion water generated by heating in the next use can be stored in the expansion mechanism 200 again, and the normal use of the expansion mechanism 200 is ensured.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
