[0027] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the internal structure of an embodiment of the heating device of the present application; Figure 2 for Figure 1 A schematic structural diagram of an embodiment of a heating device. In some embodiments, the heating device 100 includes a housing 10 and a heating element 20 .

[0028] The housing 10 has a containing space (not shown), and the housing 10 has a liquid inlet 101. The heating element 20 is located in the containing space. The housing 10 has at least a first liquid outlet 102 and a second liquid outlet 103, wherein the first liquid outlet 102 is used to connect to the flushing device 300, and the second liquid outlet 103 is a circulating liquid outlet, so that the liquid can circulate in the heating device 100 through the liquid inlet 101 and the second liquid outlet 103.

[0029] In this embodiment, the shell 10 is in the shape of a rectangular body. In some other embodiments, the shell 10 can also be in the shape of a cylinder, a table, an irregular polygon, etc. The shell 10 is used to protect and support. In addition, in this embodiment, the shell 10 is an integrally formed structure. The integrally formed shell 10 has good integrity, no parting line and connection parts, and good sealing. After the heating device 100 is placed in the container 200 containing water, the risk of water leakage of the shell 10 can be reduced. In some other embodiments, the shell 10 can also be made by profile welding, fixing connection, etc. In addition, in this embodiment, the shell 10 is a shell 10 made of steel, and the shell 10 can be made by stamping. In some other embodiments, the shell 10 can also be a shell 10 of other materials such as ceramics and plastics. In this embodiment, the heating element 20 includes a heating flow channel and a heating element located in the heating flow channel, and the heating flow channel is respectively connected to the liquid inlet 101, the first liquid outlet 102, and the second liquid outlet 103. Specifically, the heating element may be a quartz tube heating element, a ceramic heating element, a resistance wire heating element, etc. In addition, in the present embodiment, a first liquid outlet 102 and a second liquid outlet 103 are provided on the shell 10. The heating device 100 can be connected to a flushing device 300 such as a shower. In other embodiments, two, three or other numbers of first liquid outlets 102 may be provided on the shell 10, so that the heating device 100 can be connected to multiple showers and faucet flushing devices 300 at the same time, so that multiple people can wash at the same time. Figure 1 X in the figure represents the flow direction of the liquid in the heating device 100 .

[0030] In one application scenario, a shower is connected to the first liquid outlet 102 of the heating device 100, and the heating device 100 is placed in a container 200 containing water, such as a bucket or a water tank, and the first liquid outlet 102 is controlled to be opened, and the second liquid outlet 103 is controlled to be closed. Under this control, the heating device 100 is in an instant heating state. After the water in the container 200 enters the heating device 100 from the liquid inlet 101 and is heated by the heating element 20, it directly comes out from the first liquid outlet 102 and is sprayed by the shower, which can meet the user's hot water bathing needs.

[0031] In another application scenario, when the ambient temperature is lower than a preset temperature, for example, when the ambient temperature is 3 degrees, 5 degrees or below zero, the shower head is connected to the first liquid outlet 102 of the heating device 100, and the heating device 100 is placed in a container 200 containing water, such as a bucket or a water tank. The first liquid outlet 102 is first controlled to be closed, and the second liquid outlet 103 is controlled to be opened. Under this control, the heating device 100 is first in a preheating state. The water in the container 200 enters the heating device 100 from the liquid inlet 101 and is heated by the heating element 20. Then, the water comes out from the second liquid outlet 103 and returns to the container 200. It circulates and enters the heating device 100 from the liquid inlet 101 again. During the circulation of water in the heating device 100, the heating element 20 circulates and heats the water. This process can preheat the water in the container 200. For example, the heating device 100 can be controlled to be in a preheating state to preheat the water in the container 200 with a room temperature of 2 degrees to 30 degrees. After the preheating is completed, the first liquid outlet 102 is controlled to be opened and the second liquid outlet 103 is controlled to be closed, so that the heating device 100 is in an instant heating state. Then the user takes a shower again, and the preheated water is heated to an ideal temperature by the heating element 20 and then sprayed from the shower. As mentioned above, when the ambient temperature is low, the water can be preheated first, and then the preheated water is heated and sprayed from the shower. The shower water temperature can be kept stable even at low temperatures outdoors, thereby improving the user's outdoor shower experience.

[0032] Different from the prior art, the heating device 100 can heat water when placed outdoors by placing the heating device 100 in a container 200 containing water. After the water is heated, it is ejected from the flushing device 300 of the first liquid outlet 102, meeting the user's outdoor shower and other cleaning needs. In addition, the housing 10 has a first liquid outlet 102 and a second liquid outlet 103. When the outdoor temperature is low, the second liquid outlet 103 can be controlled to open, so that the water in the container 200 circulates in the heating device 100 through the liquid inlet 101 and the second liquid outlet 103, and the water can be preheated. After the water is preheated, the preheated water is heated again by the heating element 20 and ejected through the flushing device 300 of the first liquid outlet 102, which can improve the heating effect of water in a low temperature environment. When the outdoor temperature is low, the shower water temperature can be kept stable, thereby improving the user's outdoor shower experience.

Specifically, the controller 50 can be an integrated circuit chip with signal processing capabilities. In some other embodiments, the controller 50 can also be a general-purpose processor, a digital signal processor, an application-specific integrated circuit, or other devices that can receive and process signals and generate corresponding control electrical signals, without specific limitation. The controller 50 is arranged inside the heating device 100, and the signal connects the valve assembly 30 of the heating device 100, the liquid pump 40 of the heating device 100, and the heating element 20 of the heating device 100. The controller 50 can receive signals from an external control device such as a remote control or other control devices to adjust the power of the liquid pump 40 to adjust the water flow rate. The controller 50 can also control the state of the valve assembly 30 to put the heating device 100 in a preheating state or an instant heating state. The controller 50 can also control the power of the heating element 20 to adjust the temperature of the sprayed water of a flushing device 300 such as a shower. As described above, by setting the controller 50, the working state of the heating device 100 can be conveniently adjusted.

[0037] In some embodiments, the heating device 100 further includes a power supply interface 60. Specifically, the power supply interface 60 includes a wiring harness and a plug, and the wiring harness is used to supply power to the heating element 20, the liquid pump 40, the valve assembly 30, and the controller 50 of the heating device 100. The power supply interface 60 can be plugged into a household socket, and the power supply interface 60 can also be plugged into a power supply device such as a mobile power supply or a vehicle power supply, so that the user can use the heating device 100 outdoors for cleaning.

[0038] In some embodiments, the heating device 100 further includes a filter 70. The filter 70 is located at the liquid inlet 101.

The filter 70 can be a filter net, a filter element, a ceramic filter, a microporous filter, etc.

[0039] In some embodiments, the liquid inlet 101, the first liquid outlet 102, and the second liquid outlet 103 on the housing 10 of the heating device 100 are also provided with a detachably connected cover (not shown). Specifically, the cover is used to cover the hole structure on the housing 10 when the heating device 100 is not in use, so as to reduce the risk of foreign matter entering the interior of the heating device 100 and protect the heating device 100. In addition, the detachable connection method of the cover can be a threaded connection, a clamping connection, etc.

[0040] To reduce the risk of dry burning of the heating device 100 causing damage to the device, in some embodiments, a dry burning alarm is provided in the housing 10. Specifically, the dry burning alarm can be a temperature sensor, a pressure sensor, a water level sensor, etc.

[0041] In one application scenario, the user takes an outdoor shower. After the user places the heating device 100 in a container 200 filled with water and turns on the heating device 100, the controller 50 first obtains the water temperature. If the water temperature is lower than the preset low temperature, the controller 50 controls the first liquid outlet 102 to close and the second liquid outlet 103 to open. The controller 50 controls the heating device 100 to be in a preheating state. The water in the container 200 enters the heating device 100 from the liquid inlet 101 and is heated by the heating element 20. It then returns to the container 200 from the second liquid outlet 103 and circulates to enter the heating device 100 from the liquid inlet 101 again. The water circulates in the heating device 100, and the heating device 100 preheats the water in the container 200. The preset low temperature can be a reasonable temperature such as 4 degrees Celsius, 5 degrees Celsius, 6 degrees Celsius, etc. Among them, in the preheating state, the heating device 100 can be controlled to preheat the water in the container 200 to a specified temperature, and the specified temperature can be a reasonable temperature such as 25 degrees, 30 degrees, 35 degrees, etc. For example, the heating device 100 can preheat the water in the container 200 with a room temperature of 4 degrees Celsius to 30 degrees in the preheating state. After the preheating is completed, the first liquid outlet 102 is controlled to be opened and the second liquid outlet 103 is controlled to be closed, so that the heating device 100 is in an instant heating state. Then the user takes a shower again, and the preheated water is heated to the ideal temperature by the heating element 20 and then sprayed from the shower head. As mentioned above, when the ambient temperature is low, the water can be preheated first, and then the preheated water is heated and sprayed from the shower head. The shower water temperature can be maintained stable even at low outdoor temperatures, thereby improving the user's outdoor shower experience.

In addition, the housing 10 has a first liquid outlet 102 and a second liquid outlet 103. When the outdoor temperature is low, the second liquid outlet 103 can be controlled to open, so that the water in the container 200 circulates in the heating device 100 through the liquid inlet 101 and the second liquid outlet 103, which can realize the preheating of the water. After the water is preheated, the preheated water is heated again by the heating element 20 and then sprayed out through the flushing device 300 of the first liquid outlet 102, which can improve the heating effect of water in a low temperature environment. When the outdoor temperature is low, the shower water temperature can be maintained stable, thereby improving the user's outdoor shower experience.
