Abstract
Description
Technical Field
[0001] This utility model relates to the field of instant heating technology, specifically to a heating module. Background Technology
[0002] In the field of fluid heating equipment, such as instant water dispensers, boilers, or other devices that require rapid heating of liquids, the heating module is the core component for achieving efficient heat energy conversion. To improve heating efficiency, shorten heat exchange time, and achieve a more uniform fluid heating effect, existing technologies generally add a flow guiding structure inside the heating tube.
[0003] However, this design, intended to improve efficiency, presents a significant technical challenge in practical applications: the flow guiding structure (especially its end or outlet) typically needs to be connected or fitted to the liquid outlet connector of the heating module. During long-term operation, due to the combined effects of thermal expansion and contraction, fluid pressure pulsation, vibration, and material fatigue, the connection between the flow guiding pipe and the liquid outlet connector is prone to loosening or increased gaps, resulting in significant hydrodynamic noise.
[0004] This noise problem caused by structural loosening not only seriously interferes with the quietness of the equipment's operating environment, but also reduces the user's comfort experience. Summary of the Invention
[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a heating module that can effectively avoid noise generation, making the noise during structural heating lower and improving the user experience.
[0006] To achieve the above objectives, the specific solution of this utility model is as follows:
[0007] A heating module includes a heating element, an inlet connector at one end of the heating element, and an outlet connector at the other end of the heating element; a partition tube is provided inside the heating element; one end of the partition tube is connected to the inlet connector; the other end of the partition tube is connected to the outlet connector; a first sealing gasket is provided between the other end of the partition tube and the outlet connector; the inlet connector, heating element, partition tube, and outlet connector together enclose an annular cavity that communicates with both the inlet connector and the outlet connector.
[0008] Furthermore, the annular cavity is provided with a spiral component; the inner wall of the spiral component abuts against the outer wall of the septum tube; and the outer wall of the spiral component abuts against the inner wall of the heating tube.
[0009] Furthermore, in this invention, the two ends of the spiral component abut against the inlet connector and the outlet connector, respectively.
[0010] Furthermore, in this invention, the first sealing gasket is made of silicone material.
[0011] In a further embodiment of the present invention, the first sealing gasket includes a ring body and a ring platform extending radially from one end of the ring body; the other end of the diaphragm tube is sleeved on the ring body; the end wall of the other end of the diaphragm tube abuts against the ring platform.
[0012] Furthermore, the outer wall of the ring body is provided with protruding ribs.
[0013] Furthermore, in this invention, the liquid outlet connector is provided with a mounting platform; the first sealing gasket is fitted onto the outer wall of the mounting platform.
[0014] Furthermore, in this invention, a screw is connected between the liquid outlet connector and the liquid inlet connector; one end of the screw passes through the liquid outlet connector along the axial direction of the diaphragm tube and is threadedly connected to the liquid inlet connector.
[0015] Furthermore, the liquid outlet connector is equipped with a temperature probe; the temperature probe extends into the annular cavity along the axial direction parallel to the heating tube.
[0016] Furthermore, in this invention, a second sealing gasket is provided between one end of the heating tube and the liquid inlet connector; and a third sealing gasket is provided between the other end of the heating tube and the liquid outlet connector.
[0017] The beneficial effects of this utility model are as follows: by setting a first sealing gasket between the liquid outlet connector and the middle septum tube, the middle septum tube and the liquid outlet connector can be in close contact, ensuring the airtightness between the liquid outlet connector and the middle septum tube. At the same time, when the heated liquid flows through the liquid outlet connector, it will not vibrate and generate noise due to looseness, thus playing a shock absorption role. This is because metal materials and hard plastics will generate noise, while the first sealing gasket can effectively avoid the generation of noise, making the noise during the heating of the structure less, which is conducive to improving the user experience.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the present invention.
[0024] Example 1: As Figures 1 to 4 As shown, a heating module in this embodiment includes a heating tube 1, an inlet connector 2 at one end of the heating tube 1, and an outlet connector 3 at the other end of the heating tube 1. The heating tube 1 is preferably a thick-film heating tube 1, including a heating tube 1 body made of metal and a thick-film heating layer disposed on the outer peripheral wall of the heating tube 1, which has better heating effect and smaller structural volume. The inlet connector 2 and the outlet connector 3 are both made of hard plastic material. A partition tube 4 made of metal material is provided inside the heating tube 1. One end of the partition tube 4 is connected to the inlet connector 2. The other end of the partition tube 4 is connected to the outlet connector 3. A first sealing gasket 5 is provided between the other end of the partition tube 4 and the outlet connector 3. The inlet connector 2, the heating tube 1, the partition tube 4, and the outlet connector 3 together enclose and form an annular cavity 6 that is connected to both the inlet connector 2 and the outlet connector 3. This can reduce the thickness of the liquid to be heated flowing through the heating tube 1, thereby making the heating efficiency higher.
[0025] Specifically, in actual use, the heating module of this embodiment introduces the liquid to be heated (such as water) through the inlet connector 2 and then flows into the annular cavity 6 through the inlet connector 2. The heating tube 1 is powered on and heats the liquid to be heated flowing through the annular cavity 6 to form a heating liquid. The heating liquid flows out from the outlet pipe, thus forming a heating liquid flow, thereby realizing the heating of the liquid.
[0026] In this embodiment, by setting a first sealing gasket 5 between the liquid outlet connector 3 and the middle septum tube 4, the middle septum tube 4 and the liquid outlet connector 3 can be in close contact, ensuring the airtightness between the liquid outlet connector 3 and the middle septum tube 4. At the same time, when the heated liquid flows through the liquid outlet connector 3, it will not vibrate and generate noise due to looseness, thus playing a shock absorption role. This is because metal materials and hard plastics can generate noise, while the first sealing gasket 5 can effectively avoid the generation of noise, making the noise during the heating of the structure lower and improving the user experience.
[0027] like Figures 1 to 3As shown, in some embodiments of the heating module of this embodiment, a spiral component 7 is provided inside the annular cavity 6; the inner wall of the spiral component 7 abuts against the outer wall of the partition tube 4; and the outer wall of the spiral component 7 abuts against the inner wall of the heating tube 1. By providing the spiral component 7, this embodiment can form a spiral channel between the partition tube 4 and the heating tube 1, making the liquid flow within the heating tube 1 more uniformly mixed, less prone to localized liquid shortages, and less prone to the formation of mixed liquids, thus helping to ensure more accurate liquid outlet temperature and smaller liquid temperature fluctuations.
[0028] like Figures 1 to 3 As shown, in some embodiments of the heating module of this embodiment, the two ends of the spiral member 7 abut against the liquid inlet connector 2 and the liquid outlet connector 3, respectively. Through the above-described arrangement, the spiral member 7 is more stably fixed within the annular cavity 6, resulting in a more reliable and stable structure. Preferably, the spiral member 7 is a spring.
[0029] In some embodiments of the heating module of this example, the first sealing gasket 5 is made of silicone. Through the above-described configuration, this example achieves good sealing performance and high-temperature resistance.
[0030] like Figures 1 to 4 As shown, in some embodiments of the heating module of this embodiment, the first sealing gasket 5 includes a ring body 51 and an annular platform 52 extending radially from one end of the ring body 51; the other end of the septum tube 4 is sleeved on the ring body 51; the end wall of the other end of the septum tube 4 abuts against the annular platform 52. Through the above-mentioned arrangement, this embodiment further improves the airtightness between the septum tube 4 and the liquid outlet connector 3. Simultaneously, by utilizing the ring body 51 and the annular platform 52, the axial and radial directions of the septum tube 4 are tightly contacted with the liquid outlet connector 3 through the first sealing gasket 5, thereby further reducing the noise generated during heating.
[0031] In some embodiments of the heating module of this embodiment, the outer wall of the ring 51 is provided with protruding ribs. This embodiment further improves the tightness between the septum tube 4 and the liquid outlet connector 3 through the above-mentioned arrangement.
[0032] like Figures 1 to 4 As shown, in some embodiments of the heating module of this embodiment, the liquid outlet connector 3 is provided with a mounting platform 31; the first sealing gasket 5 is sleeved on the outer wall of the mounting platform 31. This embodiment uses the above-mentioned arrangement to facilitate the assembly of the first sealing gasket 5.
[0033] like Figures 1 to 4 As shown, in some embodiments of the heating module of this embodiment, the liquid outlet connector 3 is equipped with a temperature probe 9; the temperature probe 9 extends into the annular cavity 6 along the axial direction parallel to the heating tube 1. In this embodiment, by setting the temperature probe 9 at the position of the liquid outlet connector 3, the temperature of the heating liquid flowing out of the liquid outlet connector 3 is detected, so as to accurately control the heating temperature.
[0034] like Figures 1 to 3 As shown, in some embodiments of the heating module of this embodiment, a second sealing gasket 10 is provided between one end of the heating tube 1 and the liquid inlet connector 2; a third sealing gasket 20 is provided between the other end of the heating tube 1 and the liquid outlet connector 3. This embodiment, by providing the second sealing gasket 10 and the third sealing gasket 20, ensures a tight contact and better airtightness between the heating tube 1 and the second and third sealing gaskets 10 and 20, while also reducing vibration noise between the heating tube 1 and the liquid inlet connector 2 and the liquid outlet connector 3 caused by liquid flow.
[0035] like Figures 1 to 3 As shown, in some embodiments of the heating module of this embodiment, a mounting base 30 is provided on the outer peripheral wall of the heating tube 1; a thermostat 40, such as a manual thermostat 40 and an automatic thermostat 40, is provided on the mounting base 30 to prevent the risk of dry burning and make the structure safer to use.
[0036] Example 2: Figures 2 to 4 As shown, to further improve the structural robustness, the difference between this embodiment and Embodiment 1 is that a screw 8 connects the liquid outlet connector 3 and the liquid inlet connector 2; one end of the screw 8 passes through the liquid outlet connector 3 axially along the diaphragm tube 4 and is threadedly connected to the liquid inlet connector 2; the rest of the structure is the same as in Embodiment 1, and will not be described again here. This embodiment uses a screw 8 to connect the liquid outlet connector 3 and the liquid inlet connector 2, thereby making the heating element 1, the liquid outlet connector 3, and the liquid inlet connector 2 more firmly connected, resulting in a more robust structure. Specifically, the screw 8 is a bolt.
[0037] The above are merely preferred embodiments of this utility model. Therefore, any equivalent changes or modifications made in accordance with the structure, features and principles of this utility model patent application are included within the protection scope of this utility model patent application.
