Therefore, it cannot be understood as a limitation on the present invention.

[0023] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The preferred technical solution of the solar water heater of the present utility model is described below.

[0025] See first Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the solar water heater of the utility model Figure 1 , Figure 2 This is a schematic diagram of the structure of the solar water heater of the utility model Figure 2 , Figure 3 yes Figure 2 Schematic diagram of the cross section along the AA direction. Figure 1 , Figure 2 and Figure 3 As shown, the solar water heater of the utility model specifically comprises an upper water tank 1, on which a water inlet 11 is provided; a lower water tank 2, which is arranged below the upper water tank 1 to support the upper water tank 1, and on which a water outlet 21 is provided; a heat conductor 3, one end of which is inserted into the upper water tank 1 to conduct heat to the upper water tank 1; and a connecting component 4, which connects the upper water tank 1 and the lower water tank 2. Through the above arrangement, the lower water tank 2 supports the upper water tank 1, so that no additional bracket is required, which can not only reduce the cost of the solar water heater, but also save the space occupied by the solar water heater.

[0026] In the above embodiment, solar radiation irradiates on the heat conductor 3, and the heat conductor 3 absorbs the solar radiation and converts it into thermal energy. By inserting one end of the heat conductor 3 into the upper water tank 1, the heat absorbed by the heat conductor 3 can be transferred to the water in the upper water tank 1, thereby completing the heating of the upper water tank 1.

[0027] The heat conductor 3 specifically refers to a workpiece or device that can efficiently absorb solar radiation, such as a flat-plate collector or a vacuum tube. In this embodiment, the heat conductor 3 is a vacuum tube, which includes an outer tube and an inner tube. The outer wall of the inner tube of the vacuum tube is coated with a film layer for converting solar radiation into thermal energy. There is a vacuum interlayer between the outer tube and the inner tube, thereby reducing heat loss and ensuring a high thermal efficiency. At the same time, in this embodiment, the number of heat conductors 3 is multiple, and the multiple heat conductors 3 are evenly and spacedly arranged to improve the efficiency of absorbing solar radiation.

[0028] Secondly, the upper water tank 1 is provided with a water inlet 11, and the lower water tank 2 is provided with a water outlet 21. When the water in the upper water tank 1 is heated or reaches a certain set target, the water in the upper water tank 1 can flow into the lower water tank 2 for storage and heat preservation through the connecting component 4, and then the water to be heated is added to the upper water tank 1 through the water inlet 11 for heating, thereby increasing the storage capacity of hot water and the working efficiency of the solar water heater. When hot water is needed, the hot water in the lower water tank 2 for heat preservation can be directly taken through the water outlet 21, thereby improving the utilization efficiency of hot water. At the same time, by setting the connecting component 4, it can be ensured that hot water is available at any time, thereby avoiding the problem of insufficient hot water during peak water use.

[0029] In addition, when the water in the upper water tank 1 is heated, it can be directly stored in the lower water tank 2. At this time, cold water is added to the upper water tank 1 to continue heating the cold water in the upper water tank 1, avoiding the waste of solar energy resources caused by the saturation of water temperature in the upper water tank 1, thereby improving the utilization rate of energy.

[0030] Furthermore, the upper water tank 1 and the lower water tank 2 are both made of thermal insulation materials, which can effectively reduce heat loss and the impact of the external environment on the water tank temperature, improve the thermal efficiency of the solar water heater, and ensure that the water in the water tank maintains a high temperature for a long time, thereby extending the use time of hot water and reducing the waste of hot water.

[0031] Meanwhile, it should be noted that, in the present embodiment, the structural strength and size specifications of the lower water tank 2 are greater than those of the upper water tank 1, so as to achieve the purpose of supporting the upper water tank 1 and replacing the traditional water heater bracket.

[0032] In a preferred embodiment, the connecting component 4 includes: an upper connecting piece 41, one end of which is located in the upper water tank 1; a lower connecting piece 42, one end of which is connected to the other end of the upper connecting piece 41, and the other end of the lower connecting piece 42 is located in the lower water tank 2.

[0033] Among them, through the connection of the upper connecting piece 41 and the lower connecting piece 42, the water in the upper water tank 1 can flow into the lower water tank 2 through the upper connecting piece 41 and the lower connecting piece 42. In this embodiment, the upper connecting piece 41 and the lower connecting piece 42 are both connecting pipes, and both are "L"-shaped structures, so as to effectively control the direction and speed of the water flow, which is beneficial to the transfer of heat and the stability of the water temperature.

[0034] In a possible implementation, the connecting component 4 further includes a control member 43 disposed at the connection between the upper connecting member 41 and the lower connecting member 42 to connect or cut off the connection between the upper connecting member 41 and the lower connecting member 42 .

[0035] Specifically, in this embodiment, the control member 43 is a device capable of opening and closing the pipeline, such as a solenoid valve. By setting the control member 43, the connection between the upper water tank 1 and the lower water tank 2 can be selectively controlled. When the solenoid valve is in an open state, the channel between the upper connecting member 41 and the lower connecting member 42 is opened, allowing water to flow from the upper water tank 1 to the lower water tank 2. When the solenoid valve is in a closed state, the channel is closed, cutting off the flow of water. For example, by setting a specific time to open the solenoid valve, the water in the upper water tank 1 flows into the lower water tank 2 after being heated to a specific time.

[0036] Secondly, by adjusting the opening of the solenoid valve, the flow rate of water flowing through the upper connecting piece 41 and the lower connecting piece 42 can also be controlled to achieve precise regulation of the water flow.

[0037] In a possible implementation, the solar water heater further includes a first detection component 5 , which is disposed in the upper water tank 1 and electrically connected to the control component 43 ; the first detection component 5 is used to detect the temperature of water in the upper water tank 1 .

[0038] The first detection member 5 is a device capable of detecting temperature, such as a temperature detection sensor. The first detection member 5 can detect the water temperature in the upper water tank 1 and transmit the water temperature signal to the control member 43, so that the control member 43 opens or closes the connection passage between the upper connecting member 41 and the lower connecting member 42 according to a preset command. For example, when the water temperature in the upper water tank 1 reaches the set temperature, the control member 43 is turned on, so that the hot water heated in the upper water tank 1 flows into the lower water tank 2 through the upper connecting member 41 and the lower connecting member 42 for heat preservation and storage.

[0039] In a possible implementation, the solar water heater further includes a first supporting member 6 , which is disposed between the upper water tank 1 and the lower water tank 2 to support the upper water tank 1 , and the upper connecting member 41 and the lower connecting member 42 are both partially located in the first supporting member 6 .

[0040] Among them, the first supporting member 6 is arranged between the upper water tank 1 and the lower water tank 2, so as to more evenly distribute the pressure generated by the upper water tank 1, reduce stress concentration, and reduce the local pressure of the upper water tank 1 on the lower water tank 2. At the same time, the provision of the first supporting member 6 can also provide additional stability, enhance the stability of the overall structure, and reduce displacement or deformation caused by external force or vibration.

[0041] In a possible implementation, the solar water heater further includes a second detection component 7 , which is disposed in the lower water tank 2 , and is used to detect the temperature and water level of water in the lower water tank 2 .

[0042] The second detection member 7 is a device capable of detecting temperature and water level, for example, an integrated sensor combining a temperature detection sensor and a water level detection sensor, or a water temperature and water level probe.

[0043] In a specific embodiment, the second detection component 7 is connected to an external control device. For example, when the second detection component 7 detects that the water temperature in the lower water tank 2 drops to a set temperature or the water level drops to a set water level line, the temperature signal or the water level signal is sent to the external control device to provide the user with insufficient hot water.

[0044] In a possible implementation, the solar water heater further includes a heating element 8 , which is disposed in the lower water tank 2 and electrically connected to the second detection element 7 , and is used for heating the water in the lower water tank 2 .

[0045] The heating element 8 is a device capable of heating, such as an electric heating rod or an electric heating tube. In this embodiment, the heating element 8 is an electric heating tube, so that the water in the lower water tank 2 can be heated to a desired temperature in a short time. Secondly, by arranging the heating element 8 to heat the lower water tank 2 separately for user use, energy waste caused by heating the upper water tank 1 and the lower water tank 2 at the same time is avoided, and the time required for heating can also be saved.

[0046] In a specific embodiment, since the heating element 8 is electrically connected to the second detection element 7, when the second detection element 7 detects that the water temperature in the lower water tank 2 drops to a set temperature, a temperature signal is sent to the heating element 8 to enable the heating element 8 to start working; when the second detection element 7 detects that the water temperature in the lower water tank 2 rises to a set temperature, a temperature signal is sent to the heating element 8 to enable the heating element 8 to stop working.

[0047] In a possible implementation manner, the solar water heater further includes a second supporting member 9 , which is connected to the other end of the heat conductive member 3 to support the heat conductive member 3 .

[0048] The second supporting member 9 is disposed on the ground, thereby providing a stable support for the heat conducting member 3 to prevent the heat conducting member 3 from moving or being damaged when subjected to wind or other external forces.

[0049] Secondly, the heat conductor 3 is arranged at an angle with the upper water tank 1 and the lower water tank 2, so as to maximize the absorption of solar radiation. Therefore, the second supporting member 9, the upper water tank 1 and the lower water tank 2 and the ground form a triangular structure to ensure the stability of the entire solar water heater. By adjusting the second supporting member 9, the angle between the heat conductor 3 and the upper water tank 1 and the lower water tank 2 can also be adjusted to adapt to different seasonal changes and improve the hot water output efficiency.

[0050] In a possible implementation manner, a first exhaust port 12 is further provided on the upper water tank 1 .

[0051] When the water temperature of the upper water tank 1 continues to rise, the pressure inside the upper water tank 1 will change, and the gas in the water will gradually be released. These gases will form bubbles in the water, affecting the heat transfer efficiency. Therefore, it is necessary to set an exhaust port on the upper water tank 1 to discharge these gases in time to ensure the pressure balance inside the upper water tank 1.

[0052] In a possible implementation, the solar water heater further includes an exhaust member 10 , both ends of which are respectively disposed in the upper water tank 1 and the lower water tank 2 , and the exhaust member 10 is located at one end of the upper water tank 1 to form a second exhaust port 101 .

[0053] The exhaust member 10 is an exhaust pipe, and the exhaust pipe is located at one end of the upper water tank 1 to form a second exhaust port 101. Specifically, since the upper water tank 1 is arranged above the lower water tank 2 in this embodiment, if the exhaust port of the lower water tank 2 is directly opened on the lower water tank 2, it is easy to cause water to flow out of the exhaust port of the lower water tank 2, which is not easy to maintain. Therefore, by providing the exhaust member 10, the gas in the water in the lower water tank 2 can flow into the upper water tank 1 through the second exhaust port 101, and then be discharged through the first exhaust port 12, thereby ensuring the pressure balance inside the lower water tank 2.

[0054] In summary, the solar water heater of the utility model comprises an upper water tank 1, a lower water tank 2, a heat conducting member 3 and a connecting assembly 4. The lower water tank 2 is used to support the upper water tank 1. The upper water tank 1 is provided with a water inlet 11, and the lower water tank 2 is provided with a water outlet 21. One end of the heat conducting member 3 is inserted into the upper water tank 1 to conduct heat to the upper water tank 1. The connecting assembly 4 is used to connect the upper water tank 1 and the lower water tank 2. Through the above arrangement, the lower water tank 2 supports the upper water tank 1, so that there is no need to set up an additional bracket, which can not only reduce the cost of the solar water heater, but also save the space occupied by the solar water heater.

[0055] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
