[0045] As Figure 2 and Figure 4 shown, an embodiment of the present application provides a heating device 100, which is mainly used for heating water. The heating device 100 includes a housing 110 and a heating element 120.

[0046] Among them, the housing 110 includes a main body portion 111, a water inlet pipe 112, and a water outlet pipe 113. The water inlet pipe 112 and the water outlet pipe 113 are respectively located at two ends of the main body portion 111. The main body portion 111 has a receiving cavity, and the receiving cavity is respectively communicated with the water inlet pipe 112 and the water outlet pipe 113.

[0047] First mounting holes 1112 and second mounting holes 1113 are respectively formed in the end walls at two ends of the main body portion 111. The heating element 120 sequentially passes through the first mounting hole 1112, the receiving cavity, and the second mounting hole 1113 to heat the water in the receiving cavity.

[0048] In the heating device 100 provided by the embodiment of the present application, by respectively arranging the water inlet pipe 112 and the water outlet pipe 113 at two ends of the main body portion 111, the main body portion 111, the water inlet pipe 112, and the water outlet pipe 113 are integrally formed to form the entire housing 110, effectively improving the pressure-bearing capacity of the housing 110 to ensure that the heating device 100 can withstand various pressure changes during use and guarantee the use safety. The main body portion 111 has a receiving cavity respectively communicated with the water inlet pipe 112 and the water outlet pipe 113, so that external water can enter the receiving cavity through the water inlet pipe 112, and after being heated by the heating element 120 in the receiving cavity, it is discharged through the water outlet pipe 113 for user use. By respectively forming the first mounting hole 1112 and the second mounting hole 1113 on the end walls at two ends of the main body portion 111, and sequentially passing the heating element 120 through the first mounting hole 1112, the receiving cavity, and the second mounting hole 1113, the function of heating the water in the receiving cavity is realized.

[0049] Exemplarily, the main body portion 111, the water inlet pipe 112, and the water outlet pipe 113 can be integrally formed by welding with stainless steel material.

The housing 110 includes a main body portion 111, a water inlet pipe 112, and a water outlet pipe 113. By respectively arranging the water inlet pipe 112 and the water outlet pipe 113 at both ends of the main body portion 111, the main body portion 111, the water inlet pipe 112, and the water outlet pipe 113 are integrally formed to form the entire housing 110, effectively improving the pressure-bearing capacity of the housing 110 to ensure that the heating device 100 can withstand various pressure changes during use and guarantee the use safety. The main body portion 111 has a receiving cavity that communicates with the water inlet pipe 112 and the water outlet pipe 113 respectively, so that external water can enter the receiving cavity through the water inlet pipe 112, and after being heated by the heating element 120 in the receiving cavity, it is discharged through the water outlet pipe 113 for the user to use. By respectively opening a first mounting hole 1112 and a second mounting hole 1113 on the end walls at both ends of the main body portion 111, and passing the heating element 120 through the first mounting hole 1112, the receiving cavity, and the second mounting hole 1113 in sequence, the function of heating the water in the receiving cavity is realized. In addition, compared with the form in the prior art where most of the structures of the heating device are integrated on the water inlet and outlet cover, the heating device 100 proposed in the present application effectively simplifies the structure, reduces the difficulty and cost of production and maintenance replacement, and avoids the technical problem in the prior art that when a component on the water inlet and outlet cover is damaged, the entire water inlet and outlet cover needs to be replaced, resulting in high maintenance and replacement costs.
