Description

Technical Field

[0001] This utility model relates to a water tank. Background Technology

[0002] Currently, most water storage tanks used for storing drinking water are placed in a static environment, which is relatively closed. Over time, bacteria can easily grow in the water, affecting the taste and posing a health risk. To prevent bacterial growth, some static water tanks use ultraviolet (UV) lamps for sterilization. However, because UV lamps have limited penetration distance in water, their sterilization efficiency is low, and achieving complete sterilization requires a long time and high energy consumption. A small number of static water tanks are equipped with stirring devices to accelerate water flow and further enhance the sterilization effect of UV lamps. However, in these tanks with stirring devices, the stirring only agitates the water in a limited area, resulting in poor sterilization. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect of poor water circulation in the existing water storage tank and to provide a water tank.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A water tank includes a tank body, a germicidal lamp, and a stirring impeller. The tank body has a water storage cavity, and the stirring impeller is located at the lower end of the water storage cavity. The water tank also includes a vortex sleeve disposed within the water storage cavity. The vortex sleeve is sleeved around the periphery of the stirring impeller. The upper end of the vortex sleeve has an opening, and the lower end of the vortex sleeve is connected to the bottom wall of the tank body. The outer circumferential surface of the vortex sleeve has a plurality of first water permeable holes, which are spaced apart along the circumferential direction of the vortex sleeve. Each first water permeable hole is positioned below the stirring impeller.

[0006] In this design, the water tank incorporates a vortex sleeve around the impeller. The vortex sleeve and impeller work together to form a suction pump. When the impeller rotates forward, a vortex is created within the vortex sleeve, resulting in a negative pressure below the impeller. This causes water around the turbine sleeve to be drawn into the vortex sleeve through the first permeable hole. Driven by the impeller, the water then flows out from the opening above the vortex sleeve, allowing the water to circulate extensively from bottom to top within the water tank. The water is sterilized as it flows past the sterilizing lamp, resulting in excellent sterilization.

[0007] Preferably, the diameter of the vortex sleeve is between the radius and the diameter of the water storage cavity to improve the water circulation effect.

[0008] Preferably, the outer circumferential surface of the vortex sleeve also has a plurality of second water-permeable holes, the plurality of second water-permeable holes being spaced apart along the circumferential direction of the vortex sleeve, and each second water-permeable hole being positioned higher than the stirring impeller.

[0009] In this solution, by setting a second permeable hole, water can flow in or out through the second permeable hole, thereby improving the water circulation effect.

[0010] Preferably, the diameter of the second permeable hole is larger than that of the first permeable hole.

[0011] In this design, the above-mentioned structure facilitates rapid water discharge from the upper end of the impeller, thereby creating negative pressure at the lower end of the impeller.

[0012] Preferably, the second permeable hole is a rectangular hole.

[0013] In this design, the above-mentioned structural configuration facilitates the fabrication of the second permeable hole.

[0014] Preferably, the stirring impeller is located at the center of the vortex sleeve.

[0015] In this design, the above-mentioned structural configuration enhances the suction effect of the stirring impeller.

[0016] Preferably, the water tank further includes a support member and a bushing. One end of the support member is connected to the bushing, and the other end of the support member is connected to the inner wall of the vortex sleeve. There are multiple support members, which are evenly spaced along the circumferential direction of the bushing. The shaft of the stirring impeller passes through the bushing.

[0017] In this design, the impeller is fixed at the center of the vortex sleeve by a support and a bushing, which makes the impeller bear force evenly and improves the smoothness of rotation.

[0018] Preferably, the water tank further includes a control board and a motor, the control board being electrically connected to the motor, and the motor shaft being connected to the stirring impeller.

[0019] In this solution, the motor provides the driving force, the control board controls the start or stop of the motor, and the motor drives the stirring impeller to rotate, thus achieving intelligent control.

[0020] Preferably, the motor has a first operating speed, a second operating speed, and a third operating speed, ranging from low to high;

[0021] And / or, the motor is capable of driving the stirring impeller in either forward or reverse rotation.

[0022] In this solution, the motor is controlled by the control board and can operate at different speeds, thereby improving the water circulation effect while saving energy.

[0023] The motor rotates forward or backward, causing the water in the storage chamber to circulate in the forward or reverse direction, improving the circulation effect and thus enhancing the sterilization effect.

[0024] Preferably, the water tank further includes a control board and a liquid level probe. The control board is electrically connected to the liquid level probe. The liquid level probe is located in the water storage cavity and installed vertically on the tank body. A float is installed on the liquid level probe.

[0025] In this design, a level probe is used to detect the water level in the storage chamber. The float, influenced by buoyancy, will stop at different positions on the level probe depending on the water level. The control board determines whether the water level in the storage chamber is high, medium, or low based on the float's height, and then controls the motor speed accordingly, ensuring sufficient water circulation while saving energy. When the water level is high, the motor operates at the third operating speed; when the water level is medium, the motor operates at the second operating speed; and when the water level is low, the motor operates at the first operating speed, achieving sterilization while conserving energy.

[0026] Preferably, the germicidal lamp is installed on the top of the housing, and the lamp tube of the germicidal lamp extends into the water storage chamber.

[0027] In this design, the combination of the vortex sleeve and the stirring impeller allows water to flow from bottom to top. This structural arrangement ensures that all water flows towards the sterilizing lamp, improving the sterilization effect.

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0029] The positive and progressive effects of this utility model are as follows: the water tank has a vortex sleeve set around the impeller of the stirring impeller. The vortex sleeve and the stirring impeller work together to form a suction pump. When the stirring impeller rotates in the forward direction, a vortex is formed in the vortex sleeve, and a negative pressure is formed below the stirring impeller. This causes the water around the turbine sleeve to be sucked into the vortex sleeve through the first water-permeable hole. Then, driven by the stirring impeller, the water flows out from the opening above the vortex sleeve, causing the water to circulate back and forth in a large range from bottom to top in the water tank. The water is sterilized when it flows through the sterilizing lamp, resulting in a good sterilization effect. Attached Figure Description

[0050] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments described herein.

[0051] like Figures 1-7As shown, this embodiment discloses a water tank, which includes a tank body 1, a sterilizing lamp 2, and a stirring impeller 3. The tank body 1 has a water storage cavity 11, and the stirring impeller 3 is located at the lower end of the water storage cavity 11. The water tank also includes a vortex sleeve 4 disposed in the water storage cavity 11. The vortex sleeve 4 is sleeved on the periphery of the stirring impeller 3. The upper end of the vortex sleeve 4 has an opening 42, and the lower end of the vortex sleeve 4 is connected to the bottom wall of the tank body 1. The outer peripheral surface of the vortex sleeve 4 has a plurality of first water permeable holes 41, which are spaced apart along the circumferential direction of the vortex sleeve 4. Each first water permeable hole 41 is set lower than the stirring impeller 3. The water tank uses a vortex sleeve 4 installed around the impeller 3. The vortex sleeve 4 and the impeller 3 work together to form a suction pump. When the impeller 3 rotates in the forward direction, a vortex is formed in the vortex sleeve 4, creating a negative pressure below the impeller 3. This causes water around the turbine sleeve to be drawn into the vortex sleeve 4 through the first water-permeable hole 41. Then, driven by the impeller 3, the water flows out from the opening 42 above the vortex sleeve 4, allowing the water to circulate back and forth in a large range from bottom to top within the water tank. The water is sterilized when it flows past the sterilizing lamp 2, resulting in excellent sterilization effect.

[0052] Preferably, the diameter of the vortex sleeve 4 is between the radius of the water storage cavity 11 and the diameter of the water storage cavity 11, so as to improve the water circulation effect and thus improve the sterilization effect.

[0053] like Figure 7 As shown, in this embodiment, the stirring impeller 3 has a three-pronged structure, and one side edge of the blade is set as a flanged structure, which can stir more water during the stirring process and improve stirring efficiency; the other side edge of the blade is set as a beveled structure to reduce rotational resistance and save energy.

[0054] like Figure 3 and Figure 4 As shown, due to the cooperation of the vortex sleeve 4 and the stirring impeller 3, the water flows from bottom to top. The germicidal lamp 2 is installed on the top of the box 1, and the lamp tube of the germicidal lamp 2 extends into the water storage chamber 11, so that the water can flow to the germicidal lamp 2, thereby improving the sterilization effect.

[0055] In this embodiment, the germicidal lamp 2 shines downwards at an angle of 120 degrees, resulting in a more significant sterilization effect and better sterilization efficiency.

[0056] like Figures 3-6 As shown, the outer circumferential surface of the vortex sleeve 4 also has several second water-permeable holes 43. These second water-permeable holes 43 are spaced apart along the circumferential direction of the vortex sleeve 4, and each second water-permeable hole 43 is positioned higher than the stirring impeller 3. By providing the second water-permeable holes 43, water can flow in or out through the second water-permeable holes 43, thereby improving the water circulation effect.

[0057] The diameter of the second water-permeable hole 43 is larger than that of the first water-permeable hole 41, which facilitates water to be discharged from the upper end of the stirring impeller 3 so as to form a negative pressure at the lower end of the stirring impeller 3.

[0058] In this embodiment, the second water-permeable hole 43 is a rectangular hole, which facilitates the processing of the second water-permeable hole 43.

[0059] Preferably, the stirring impeller 3 is located at the center of the vortex sleeve 4, making full use of the internal space of the vortex sleeve 4 to make the suction effect generated by the stirring impeller 3 better.

[0060] like Figure 5 and Figure 6 As shown, the water tank also includes a support member 5 and a bushing 6. One end of the support member 5 is connected to the bushing 6, and the other end of the support member 5 is connected to the inner wall of the vortex sleeve 4. There are multiple support members 5, which are evenly spaced along the circumferential direction of the bushing 6. The rotating shaft of the stirring impeller 3 passes through the bushing 6. The stirring impeller 3 is fixed at the center of the vortex sleeve 4 by the support member 5 and the bushing 6, so that the stirring impeller 3 is subjected to uniform force and the rotation stability is improved.

[0061] The water tank also includes a control board (not shown in the figure) and a motor (not shown in the figure). The control board is electrically connected to the motor, and the motor shaft is connected to the stirring impeller 3. The motor provides driving force, and the control board controls the start or stop of the motor. The motor drives the stirring impeller 3 to rotate.

[0062] In this embodiment, the motor has a first operating speed, a second operating speed, and a third operating speed, ranging from low to high. The motor is controlled by a control board and can operate at different speeds, saving energy without reducing the water circulation effect.

[0063] Of course, in other embodiments, the operating speed of the motor can be set by the user.

[0064] The motor can drive the stirring impeller 3 to rotate forward or reverse, so that the water in the water storage chamber 11 circulates in the forward or reverse direction, improving the circulation effect and thus improving the sterilization effect.

[0065] like Figure 1 , Figure 2 and Figure 4As shown, the water tank also includes a level probe 7. The control board is electrically connected to the level probe 7. The level probe 7 is located in the water storage chamber 11 and is installed vertically on the tank body 1. A float 71 is installed on the level probe 7. The level probe 7 is used to detect the water level in the water storage chamber 11. Due to buoyancy, the float 71 will stop at different positions on the level probe 7 depending on the water level. The control board determines whether the water level in the water storage chamber 11 is high, medium, or low based on the height of the float 71 on the level probe 7, and then controls the motor speed to save energy. When the water storage chamber 11 is at a low level, the motor can operate at the first operating speed; when the water storage chamber 11 is at a medium level, the motor can operate at the second operating speed; and when the water storage chamber 11 is at a high level, the motor can operate at the third operating speed, saving energy while completing sterilization.

[0066] For example, when the level probe 7 detects a high level in the water tank (the water level is 80% or more of the tank height), the motor needs to operate at the third working speed to provide the impeller 3 with a large torque and speed to quickly agitate the water tank and complete sterilization. When the level probe 7 detects a medium level in the water tank (the water level is between 30% and 80% of the tank height), the motor needs to operate at the second working speed to provide the impeller 3 with a relatively small torque and speed (such as 50% of the rated power), saving more energy and completing sterilization. When the level probe 7 detects a low level in the water tank (the water level is 30% or less of the tank height), the motor needs to operate at the first working speed to provide the impeller 3 with a small torque and speed (such as 30% of the rated power), saving more energy and completing sterilization.
