Description

Technical Field

[0001] This utility model relates to the field of electronic steam generator technology, specifically a portable electronic steam generator. Background Technology

[0002] An electronic vapor generator is a device that converts electrical energy into heat energy to produce vapor or aerosol by heating liquids (such as water, e-liquid, special solutions, etc.). It is commonly used in the fields of electronic cigarettes (atomizers), household / industrial humidifiers, medical / laboratory equipment, and industrial cleaning.

[0003] As people's demands for the portability of electronic steam generators increase, the size of electronic steam generators is also becoming smaller and smaller. Therefore, the size of electronic steam generators also needs to be made smaller. Thus, in order to maintain high heating efficiency in a smaller size, a portable electronic steam generator is provided. Utility Model Content

[0004] The purpose of this invention is to provide a portable electronic steam generator in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable electronic steam generator, comprising a steam generator assembly consisting of an inlet tank, an inlet pipe, an outlet tank, and an outlet pipe. The inlet pipe and the outlet pipe are respectively fixed to one end of the inlet tank and the outlet tank and are in communication with the inner cavities of the inlet tank and the outlet tank. An "N"-shaped heat exchange channel consisting of a U-shaped connecting box and an S-shaped heat exchange flat tube is provided between the inlet tank and the outlet tank. The outlet tank is provided in three sets, one set of which is fixed between the inlet tank and an inlet pipe, the second set of which is fixed between two U-shaped connecting boxes, and the third set of which is fixed between another U-shaped connecting box and the outlet tank, for realizing the connection between the inlet tank and the outlet tank.

[0006] A PTC semiconductor heater is installed between the inlet pipe and the U-shaped connecting box, between the two U-shaped connecting boxes, and between the U-shaped connecting box and the outlet tank. The S-shaped heat exchange flat tube is vertically shaped like an "S" and fits against the side of the PTC semiconductor heater. The PTC semiconductor heater is used to heat the liquid inside the S-shaped heat exchange flat tube.

[0007] As a further improvement of this utility model: multiple S-shaped heat exchange flat tubes are arranged along the long side of the inlet pipe, the U-shaped connecting box, and the outlet tank, and the multiple S-shaped heat exchange flat tubes are arranged and attached in sequence.

[0008] As a further improvement of this utility model: S-shaped heat exchange flat tubes are provided on both sides of the PTC semiconductor heater, and the contact surface between the S-shaped heat exchange flat tubes and the PTC semiconductor heater is horizontal.

[0009] As a further improvement of this invention, the long side length of the PTC semiconductor heater is greater than the distribution length of the S-shaped heat exchange flat tube.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By using a structure with multiple S-shaped heat exchange flat tubes, liquid can be diverted and refined. In conjunction with the "S"-shaped trajectory of the S-shaped heat exchange flat tubes, the heat exchange area between the liquid and the PTC semiconductor heater can be effectively increased. Furthermore, the structure with S-shaped heat exchange flat tubes on both sides of a single PTC semiconductor heater can further improve the heating efficiency of the liquid. Thus, even with a relatively short length of S-shaped heat exchange flat tubes, the heating efficiency of the liquid is guaranteed, thereby meeting the structural requirements of small-volume steam generator components.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3In this embodiment of the present invention, a portable electronic steam generator includes a steam generator assembly 1 consisting of an inlet tank 101, an inlet pipe 102, an outlet tank 104, and an outlet pipe 105. The inlet pipe 102 and the outlet pipe 105 are respectively fixed to one end of the inlet tank 101 and the outlet tank 104 and are in communication with the inner cavity of the inlet tank 101 and the outlet tank 104. An "N"-shaped heat exchange channel consisting of a U-shaped connecting box 103 and an S-shaped heat exchange flat pipe 106 is provided between the inlet tank 101 and the outlet tank 104. The outlet tank 104 is provided in three sets. One set of outlet tanks 104 is fixed between the inlet tank 101 and one inlet pipe 102. The second set of outlet tanks 104 is fixed between two U-shaped connecting boxes 103. The third set of outlet tanks 104 is fixed between another U-shaped connecting box 103 and the outlet tank 104, which is used to realize the connection between the inlet tank 101 and the outlet tank 104.

[0018] A PTC semiconductor heater 2 is installed between the water inlet pipe 102 and the U-shaped connecting box 103, between the two U-shaped connecting boxes 103, and between the U-shaped connecting box 103 and the water outlet tank 104. The S-shaped heat exchange flat tube 106 is vertically shaped like an "S" and fits against the side of the PTC semiconductor heater 2. The PTC semiconductor heater 2 is used to heat the liquid inside the S-shaped heat exchange flat tube 106.

[0019] Multiple S-shaped heat exchange flat tubes 106 are arranged along the long side of the inlet pipe 102, the U-shaped connecting box 103, and the outlet tank 104, and the multiple S-shaped heat exchange flat tubes 106 are arranged and attached in sequence.

[0020] Both sides of the PTC semiconductor heater 2 are provided with S-shaped heat exchange flat tubes 106, and the contact surface between the S-shaped heat exchange flat tubes 106 and the PTC semiconductor heater 2 is horizontal.

[0021] In this embodiment: When the steam generator is in use, the liquid to be heated is transported to the water inlet tank 101 through the water inlet pipe 101, and then diverted to the first set of S-shaped heat exchange flat tubes 106. At this time, it is heated by the first PTC semiconductor heater 2 to realize the first heating operation.

[0022] Afterwards, the liquid that has been heated for the first time flows into the first U-shaped connecting box 103 and then flows into the second set of S-shaped heat exchange flat tubes 106, where it is heated a second time by the second PTC semiconductor heater 2.

[0023] Then, the liquid after secondary heating flows into the second U-shaped connecting box 103 and is diverted to the third set of S-shaped heat exchange flat tubes 106. It is heated three times by the third PTC semiconductor heater 2 and finally flows into the outlet tank 104 and is finally output through the outlet pipe 105.

[0024] During the above operation, the liquid can be divided and refined by the structure of multiple S-shaped heat exchange flat tubes 106. In conjunction with the "S"-shaped trajectory of the S-shaped heat exchange flat tubes 106, the heat exchange area between the liquid and the PTC semiconductor heater 2 can be effectively increased.

[0025] Furthermore, the structure of S-shaped heat exchange flat tubes 106 is provided on both sides of the individual PTC semiconductor heater 2, which can further improve the heating efficiency of the liquid. Based on the above structure, the heating efficiency of the liquid can be guaranteed even with a shorter length of the S-shaped heat exchange flat tubes 106, thereby meeting the structural requirements of the small volume steam generator assembly 1.

[0026] Please refer to this carefully. Figures 1-3 The length of the long side of the PTC semiconductor heater 2 is greater than the distribution length of the S-shaped heat exchange flat tube 106.

[0027] In this embodiment, this structure enables the PTC semiconductor heater 2 to heat all of the S-shaped heat exchange flat tubes 106.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
