Description

Technical Field

[0001] This utility model relates to the field of drinking water heating technology, and in particular to a connection structure between the heating element and the water pump of an instant heating module. Background Technology

[0002] Instantaneous heating modules are now widely used in household appliances such as water dispensers and water purifiers. They eliminate the need for pre-boiling water and long waiting times, providing instant hot water and great convenience to consumers. Currently, the heating element and water pump in instantaneous heating modules of water purifiers and other water-using equipment are mostly connected via silicone tubing and secured with cable ties. This connection method has the following disadvantages: 1. Poor manufacturability; the depth of the water pump insertion into the silicone tubing is uncontrollable. 2. The silicone tubing absorbs odors, leading to an unpleasant smell in the water after a period of use. 3. The heating element typically has a lifespan of over 2000 hours, while the water pump only lasts 500 hours. When the water pump fails, the silicone tubing and cable ties make pump replacement inconvenient, requiring complete replacement during repairs and resulting in waste. Utility Model Content

[0003] This invention aims to overcome the shortcomings of the prior art by providing a connection structure between the heating element and the water pump of an instant heating module. The water inlet pipe of the heating element and the water outlet pipe of the water pump are directly connected by a nut, which effectively improves manufacturability and facilitates the miniaturization design of the heating module. At the same time, it eliminates the need for silicone tubing, effectively reducing the formation of odors. Furthermore, by loosening or tightening the nut, the water pump can be easily disassembled and replaced, greatly reducing maintenance costs.

[0004] To achieve the above objectives, this utility model provides a connection structure between the heating element and the water pump of an instant heating module, including a heating element with a water inlet pipe and a water pump with a water outlet pipe. A nut is movably and limitably installed on the water inlet pipe of the heating element, and an external thread section is provided at the end of the water outlet pipe of the water pump. The heating element and the water pump are connected by screwing the nut onto the thread section of the water outlet pipe.

[0005] The water inlet pipe is further configured such that its end is provided with a flange formed after the nut is inserted, which is used to prevent the nut from coming off.

[0006] A further feature is provided: after the nut is inserted, the end of the water inlet pipe is fitted with an anti-detachment component.

[0007] A further feature is provided: a sealing gasket is provided inside the nut between the inlet and outlet water pipes.

[0008] Further configuration: The nut is made of stainless steel.

[0009] Compared with the prior art, the present invention has a simple and reasonable structure. The water inlet pipe of the heating element and the water outlet pipe of the water pump are directly connected by a nut, which effectively improves manufacturability and is conducive to the miniaturization design of the heating module. At the same time, the silicone tube is eliminated, which effectively reduces the formation of odor. Furthermore, by loosening or tightening the nut, the water pump can be easily disassembled and replaced, which greatly reduces maintenance costs. Attached Figure Description

[0016] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0017] The connection structure between the heating element 10 and the water pump 20 of the instant heating module of this utility model is as follows: Figure 1 As shown, it includes a heating element 10 with a water inlet pipe 11 and a water pump 20 with a water outlet pipe 21. The water outlet pipe 21 of the water pump 20 is connected to the water inlet pipe 11 of the heating element 10. The water pump 20 is used to pump the water required for heating to the heating element 10. The heating element 10 has a heating flow cavity for heating the flowing water.

[0018] In this embodiment, as Figure 2As shown, a nut 30 is movably and limitably installed on the water inlet pipe 11 of the heating element 10, that is, the end of the water inlet pipe 11 has an anti-detachment structure to prevent the nut 30 from coming off. The end of the water outlet pipe 21 of the water pump 20 has an external thread section 211. By aligning the water outlet pipe 21 with the nut 30 and rotating the nut 30 to tighten and fix the nut 30 on the external thread section 211 of the water outlet pipe 21, the heating element 10 and the water pump 20 are fixedly connected. In this way, by loosening or tightening the nut 30, the water pump 20 can be easily disassembled and replaced, effectively reducing maintenance costs.

[0019] In the above scheme, such as Figure 3 and Figure 4 As shown, a sealing gasket 40 is preferably provided inside the nut 30 between the water inlet pipe 11 and the water outlet pipe 21. The sealing gasket 40 is clamped and held between the ends of the water inlet pipe 11 and the water outlet pipe 21, thus sealing the water and preventing leakage.

[0020] In this embodiment, the nut 30 is made of stainless steel, which does not absorb odors. Example

[0021] like Figure 3 As shown, the anti-detachment structure on the water inlet pipe 11 of the heating element 10 is a flange 111, which is formed by the secondary processing of the flange 111 after the nut 30 is inserted into the water inlet pipe 11. Example

[0022] like Figure 4 As shown, the anti-detachment structure on the water inlet pipe 11 of the heating element 10 is an anti-detachment component 50. The anti-detachment component 50 is a pin or anti-detachment pin that passes through the end of the water inlet pipe 11 after the nut 30 is installed on the water inlet pipe 11. Preferably, the connection between the anti-detachment component 50 and the water inlet pipe 11 is sealed with waterproof glue.

[0023] Compared with the prior art, the present invention has a simple and reasonable structure. The water inlet pipe of the heating element and the water outlet pipe of the water pump are directly connected by a nut, which effectively improves manufacturability and is conducive to the miniaturization design of the heating module. At the same time, the silicone tube is eliminated, which effectively reduces the formation of odor. Furthermore, by loosening or tightening the nut, the water pump can be easily disassembled and replaced, which greatly reduces maintenance costs.

[0024] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
