Description

Technical Field

[0001] This utility model relates to toilet technology, and more specifically, to a first water tank, a water tank assembly, and a toilet. Background Technology

[0002] The water circuit control of smart toilets is typically done in a point-to-point, line-to-line manner. After the water circuit branches off from the angle valve, the flushing water circuit of the smart toilet and the human body washing system of the smart toilet seat are used separately. Independent control of the water circuit has corresponding advantages, such as simple connection logic and no need to consider other related applications; however, the disadvantage is that it results in more connecting pipes between modules, more connecting parts, and thus a larger space requirement for installation.

[0003] Furthermore, independent control of the water circuit results in related functional components performing only one function, failing to effectively improve component utilization and wasting control board resources. For example, the water inlet module performs the same function as controlling the water inlet of the smart toilet seat's human body washing system and the smart toilet flushing system, and normally their functions are staggered, avoiding simultaneous use. However, with each module operating independently, its functional tasks become very limited, and a single water circuit system requires two sets of water inlet modules, leading to resource waste.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0042] like Figures 1-9 As shown, this embodiment of the utility model provides a water tank assembly including a first water tank 1 and a second water tank 2. The first water tank 1 is connected to the second water tank 2 and can replenish water to the second water tank 2. The first water tank 1 can supply water for a human body washing system, and the second water tank 2 can supply water for a toilet flushing system.

[0043] like Figure 1 , Figure 2As shown, the first water tank 1 includes a tank body 10 and a float 3. The tank body 10 has a water-filled inner cavity 101 and a connecting port 102 connecting the water-filled inner cavity 101 to the outside. The float 3 is disposed outside the tank body 10 and is movably fitted with the connecting port 102. The float 3 includes a first working state with the connecting port 102 open (see Figure 1). Figure 6 , Figure 7 , Figure 10 The second working state of blocking the connection port 102 (see) Figure 8 , Figure 9 , Figure 11 In this embodiment, the float 3 can switch between a first working state and a second working state under the influence of external water flow, water level, and its own weight.

[0044] In one exemplary embodiment, the float 3 can switch between a first operating state and a second operating state under the action of external water flow, water level, and a reset element. The reset element can be a spring or similar component capable of resetting the float 3.

[0045] In another exemplary embodiment, the float 3 can switch between a first state and a second state under the combined action of the external water flow level, the gravity of the float 3, and the reset element.

[0046] In this embodiment of the invention, the connecting port 102 connects the first water tank 1 and the second water tank 2. The float 3 of the first water tank 1 can open or close the connecting port 102 under the combined action of the water level in the second water tank 2 and its own weight or a reset element. Figure 6 As shown, when the water level in the second water tank 2 drops, the float 3 opens the connection port 102 under its own weight or the action of the reset element, allowing water to be replenished to the second water tank 2 through the first water tank 1. Figure 7 As shown, when the water level in the second water tank 2 rises to full, the float 3 rises under the buoyancy of the water in the second water tank 2 and blocks the connection port 102.

[0047] The water tank assembly of this utility model has a communication port 102 connecting the first water tank 1 to the second water tank 2, and a float 3 is installed at the communication port 102. The float 3 can open or close the communication port 102 under the combined action of the water level in the second water tank 2 and its own weight or a reset element, so that the first water tank 1 can replenish the second water tank 2 and the water tank assembly can have continuous water supply. Therefore, the second water tank 2 does not need to be designed with a separate water inlet component, thereby reducing the complexity of connection and control, reducing costs, saving space, and making the structure simple and reliable.

[0048] In this embodiment, the first water tank 1 is located inside the second water tank 2, and the lowest liquid level of the first water tank 1 is higher than the lowest liquid level of the second water tank 2, so as to ensure that the water in the first water tank 1 can flow into the second water tank 2 to replenish the second water tank 2. In other embodiments, the first water tank 1 may also be arranged outside the second water tank 2 and connected by a connecting pipe, which is not limited here.

[0049] like Figure 3 As shown, the float 3 includes a cylindrical body 30 capable of blocking the communication port 102, and a plurality of locking arms 31 located at the top of the cylindrical body 30 and engaged with the first water tank 1. The cylindrical body 30 is located outside the first water tank 1 and inside the second water tank 2, and the locking arms 31 extend from the communication port 102 into the first water tank 1 and engage with the first water tank 1.

[0050] The end of the clamping arm 31 is provided with multiple outward-curving claws 310 capable of gripping the bottom wall of the first water tank 1. The multiple clamping arms 31 are arranged at intervals along the circumference of the cylinder 30, and the intervals between adjacent clamping arms 31 form water passage gaps 311, so that water flows out from the water passage gaps 311 when the connecting port 102 is opened. A cavity 301 is provided at the bottom end of the cylinder 30 (see...). Figure 2 The concave cavity 301 can increase the force of the water flow on the float 3. The top of the cylinder 30 is provided with a water-sealing gasket 32 ​​that can seal the connection port 102. The water-sealing gasket 32 ​​can increase the sealing performance of the float 3 when sealing the connection port 102.

[0051] In this embodiment of the invention, the connecting port 102 is located at the lower part of the water tank body 10, thereby enabling the first water tank 1 to replenish the second water tank 2 in a timely manner. Of course, in other embodiments, the connecting port 102 may also be located in other positions such as the side wall, and this is not limited here.

[0052] like Figure 2 As shown, the first water tank 1 includes a liquid level sensor 4 disposed within the tank body 10, configured to be connected to an inlet valve (not shown) to control the inlet valve to replenish the first water tank 1. Figure 6 , Figure 8 As shown, when the water level in the first water tank 1 drops due to water use in the first water tank 1 or the second water tank 2, and when the liquid level sensing device 4 detects that the liquid level has dropped to a predetermined value, the water inlet valve is controlled to replenish water to the first water tank 1.

[0053] like Figure 4As shown, the water-filled inner cavity 101 of the first water tank 1 includes an inlet cavity 1011 and a pumping cavity 1012, which are partially separated by a baffle plate 1013. The baffle plate 1013 is provided with multiple baffle ribs 1014. The first water tank 1 also includes an inlet pipe 5 located in the inlet cavity 1011 and a pumping pipe 6 located in the pumping cavity 1012. The inlet pipe 5 and the pumping pipe 6 are installed on an inlet / outlet adapter 7. By partially isolating the inlet cavity 1011 and the pumping cavity 1012, the first water tank 1 can prevent the water flow from affecting the liquid level sensing device 4, thereby ensuring the accuracy of liquid level detection.

[0054] like Figure 6 , Figure 10 As shown, in the initial state, neither the first water tank 1 nor the second water tank 2 has any water stored. The liquid level sensing device 4 controls the water inlet valve (not shown) to open. At this time, tap water enters the first water tank 1 through the water inlet / outlet adapter 7 and the water inlet pipe 5. At this time, the float 3 falls due to its own gravity, and the connecting port 201 is in the open state. The water flows out from the gap 311 between the locking arms 30 of the float 3 and enters the second water tank 2, thereby replenishing the second water tank 2 synchronously.

[0055] like Figure 7 , Figure 11 As shown, when the second water tank 2 is gradually filled with water, the water level reaches the position of the float 3 and the float 3 is raised. The water-stopping rubber pad 32 cooperates with the connecting port 102 to block the connecting port 102, and the water flow can no longer enter the second water tank 2. The first water tank 1 continues to replenish water to the high liquid position and stops water intake.

[0056] like Figure 8 As shown, when water is used in the first water tank 1, the water level in the first water tank 1 drops, while the water level in the second water tank 2 remains unchanged. When the water level drops to a certain position, the liquid level sensing device 4 controls the water inlet valve to replenish water to the first water tank 1.

[0057] like Figure 9 As shown, when water is used in the second water tank 2, the water level in the second water tank 2 drops, the float 3 loses buoyancy and descends, the connecting port 102 is opened, and water from the first water tank 1 flows into the second water tank 2 through the connecting port 102. When the liquid level in the first water tank 1 drops to a predetermined value, the liquid level sensing device 4 controls the inlet valve to start replenishing water until both the first water tank 1 and the second water tank 2 are full (e.g., Figure 9 (As shown).

[0058] The water tank assembly of this utility model can achieve continuous water use for the first water tank 1 and the second water tank 2 by setting the float 3.

[0059] As Figures 12-14As shown, this embodiment of the utility model also provides a toilet 100, including: a toilet body 1, and a human body washing system and a toilet flushing system installed on the toilet body 100a. The first water tank 1 in the water tank assembly supplies water to the human body washing system, and the second water tank 2 in the water tank assembly supplies water to the toilet flushing system.

[0060] The human body washing system includes a first pressurization device 81, a heating device (not shown), and a cleaning device 82. The first pressurization device 81 pressurizes the water in the first water tank 1 and then delivers it to the cleaning device 82 to wash the human body. The heating device heats the water in the first water tank 1 and then supplies it to the cleaning device 82. The cleaning device 82 is a device used for washing the human body; its specific structure can be found in existing technology and will not be described in detail here.

[0061] The toilet flushing system includes a second pressurizing device, a water distribution valve, a siphon nozzle, and a brush nozzle. The second pressurizing device increases the water output from the second water tank 2 and supplies it to the water distribution valve, which splits the water into two streams, supplying the siphon nozzle and the brush nozzle respectively, to flush the toilet 100. Both the first pressurizing device 81 and the second pressurizing device can be water pumps.

[0062] like Figure 12 , Figure 13 As shown, the toilet 100 also includes a base 9, which is mounted on the toilet body 100a. The washing system is located on the upper part of the base 9, and the water tank assembly is located below the base 9. The base 9 integrates the water tank assembly, the human body washing system, and the toilet flushing system.
