Description

Technical Field

[0001] This application relates to the field of drinking water treatment equipment technology, specifically to a liquid heating integrated component. Background Technology

[0002] In many water-heating devices, such as water purifiers and water dispensers, liquid heating devices are an important component. Traditional liquid heating devices are usually assembled from several independent parts, including heating elements, housings, inlet and outlet water pipes, and temperature control systems.

[0003] Taking the liquid heating device in a water purifier as an example, the traditional design usually installs the heating element separately in a shell, and then connects the inlet and outlet water ends to the external water system through multiple connectors, and then fixes the shell to the machine body bracket through multiple connectors. This design has several obvious drawbacks: each component needs to be installed and connected separately, making the assembly process cumbersome, requiring a lot of manual labor and time, and prone to installation errors, leading to problems such as leaks or poor heating performance; because each component is relatively independent, the overall structure is relatively loose, requiring a large installation space. In some space-constrained devices, such as small water purifiers, traditional liquid heating devices may occupy too much space, affecting the layout of other components and the overall compactness of the equipment; there are many connection points between multiple components and with the machine frame, increasing the risk of leaks and malfunctions. For example, the interfaces of connecting pipes and the connection between the heating element and the end cap are all places where leaks are likely to occur or components may be damaged. Once a leak occurs, it will not only waste water resources, but may also damage other parts of the equipment and even cause safety accidents. Moreover, due to the large number of components, the number of failure points also increases accordingly, making maintenance and repair more difficult and requiring professional technicians and tools.

[0004] Therefore, in order to solve the above problems, there is an urgent need in the field for a more integrated, compact and efficient liquid heating component to improve the performance and reliability of liquid heating equipment and reduce production costs and installation and maintenance difficulties. Utility Model Content

[0005] The purpose of this application is to provide an integrated liquid heating assembly, aiming to solve the problems of complex assembly, large space occupation, and low reliability of existing liquid heating devices. By integrating the heating tube, inlet end cap, outlet end cap, upper shell, and lower shell together, a compact, easy-to-install, highly reliable, and thermally efficient liquid heating assembly is formed.

[0006] The technical solution adopted in this application is as follows:

[0007] A liquid heating integrated assembly includes an upper housing, a lower housing, a heating tube, an inlet cap, and an outlet cap. The upper housing and the lower housing cooperate to form a protective cavity surrounding the heating tube. Both ends of the protective cavity have clearance openings. The two ends of the heating tube are respectively connected to the inlet cap and the outlet cap through the clearance openings. The inlet cap has an inlet channel for water to enter the heating tube, and the outlet cap has an outlet channel for water to exit the heating tube. Both ends of the upper housing are fixedly connected to the inlet cap and the outlet cap, and both ends of the lower housing are fixedly connected to the inlet cap and the outlet cap, thus forming a fixedly integrated structure of the heating tube, the inlet cap, the outlet cap, the upper housing, and the lower housing.

[0008] In this technical solution, the heating tube is surrounded by a protective cavity formed by the upper and lower shells, and the inlet and outlet end caps are fixedly connected. This achieves an integrated assembly design of the heating tube, upper shell, lower shell, inlet end cap, and outlet end cap. This not only protects the heating tube from external impacts and environmental influences and provides heat insulation, but also facilitates overall installation and maintenance. When installing this component on an external structure, it also helps save on support structure. For example, by simply setting structures on the upper and lower shells that cooperate with the external structure, the inlet and outlet end caps can be stably installed simultaneously through a linkage, ensuring the stable installation of the upper and lower shells on the external structure. In particular, for operating conditions with water pump vibration, connecting them as a single structure helps improve vibration resistance and ensure long-term stability. Thanks to this integrated assembly structure, the reliability of the connection between the inlet and outlet end caps and the heating tube, as well as the water circuit sealing, are improved, reducing the risk of leakage.

[0009] Both ends of the upper housing and the lower housing are provided with outwardly extending connecting pieces. The water inlet end cap and the water outlet end cap are provided with connecting parts. The connecting pieces and the connecting parts are provided with corresponding through holes, and are fixedly connected by fasteners passing through the through holes of the connecting pieces and the through holes of the connecting parts.

[0010] In this technical solution, the connecting piece and the through hole of the connecting part correspond to each other and are connected by fasteners, realizing a detachable fixing method, which facilitates the assembly and disassembly of components, and allows for repair or replacement without damaging the parts, thereby improving the maintainability and service life of the product.

[0011] The connecting part is provided with a clamping groove, and the connecting pieces at the same end of the upper shell and the lower shell are stacked and clamped in the clamping groove by the connecting part.

[0012] In this technical solution, the clamping groove structure of the connecting part clamps the upper and lower shells together using connecting pieces that can hold them in place. After clamping, fasteners are used for through-fastening, increasing the connection area and stability, effectively dispersing the fastening force, and preventing structural damage caused by localized stress concentration. Simultaneously, the limiting effect of the clamping groove prevents relative displacement between the upper and lower shells during use, improves the fastener's anti-loosening capability, and helps ensure the integrity of the protective cavity.

[0013] The inlet cap and the outlet cap are respectively fitted to the heating tube along the axial direction of the heating tube. The clamping groove has an opening along the axial direction of the heating tube, and the edge of the clamping groove opening has an inlet slope to guide the connecting piece into the clamping groove.

[0014] In this technical solution, the axial opening of the clamping groove along the heating pipe and the design of the guide slope allow the connecting piece to smoothly slide into the clamping groove simultaneously during the docking of the inlet and outlet end caps with the heating pipe. This saves assembly steps and reduces assembly difficulty and time costs. The guiding effect of the guide slope also avoids hard collisions between the connecting piece and the edge of the clamping groove, simplifying assembly operations, reducing alignment difficulty, and minimizing the risk of damage during assembly.

[0015] The connecting pieces are provided on the edges of the upper housing and the lower housing, and at least two connecting pieces are provided at the same end of the upper housing and the lower housing.

[0016] In this technical solution, multiple connecting pieces are set in both the upper and lower shells to form a multi-point fixing structure, which enhances the deformation resistance of the components under stress. It is especially suitable for liquid flow or vibration environments, ensuring the long-term stability of the connection between the components.

[0017] Both the upper housing and the lower housing are provided with outwardly extending mounting pieces, each mounting piece having a mounting hole. The mounting pieces of the upper housing and the lower housing are stacked and mounted on an external structure through the mounting holes.

[0018] In this technical solution, the mounting plates of the upper and lower housings are stacked and connected to the external structure through mounting holes. Specifically, fasteners such as screws are used to pass through the mounting holes and connect to the external structure, ensuring installation stability. This design allows the components to be quickly positioned and fixed as a whole, while distributing installation stress and avoiding structural damage caused by excessive local stress.

[0019] The water inlet end cover is provided with a water pump mounting position and a water inlet pipe. A water pump is installed on the water pump mounting position. The water outlet port of the water pump is connected to the water inlet channel, and the water inlet pipe is connected to the water inlet port of the water pump.

[0020] In this technical solution, the integrated design of the water pump and the inlet end cap further enhances the integration of the components and shortens the water flow path between the water pump and the heating pipe, reducing energy loss and leakage points. The water pump is directly connected to the inlet channel, improving liquid delivery efficiency, while the overall structure is more compact, saving installation space.

[0021] The water pump mounting position is provided with multiple positioning holes that pass through both ends of the water inlet end cover. Fasteners pass through the positioning holes and are fixedly connected to the water pump. The heating pipe and the water pump are located on the same side of the water inlet end cover.

[0022] In this technical solution, the matching of positioning holes and fasteners ensures accurate installation of the water pump and the water inlet end cap. The design of the heating tube and the water pump being located on the same side helps to reduce redundant space and make the component structure more compact.

[0023] The inlet cap is equipped with an inlet water temperature detector and a flow rate detector, which are used to detect the water temperature and flow rate of the water entering the heating tube, respectively; the outlet cap is equipped with an outlet water temperature detector, which is used to detect the water temperature of the water exiting the heating tube.

[0024] In this technical solution, the inlet water temperature detection device and the outlet water temperature detection device can monitor the inlet water temperature and the outlet water temperature in real time, respectively, and the flow detection device can monitor the water flow in real time, which facilitates temperature and flow control and reduces the risk of dry burning, overheating, or underheating.

[0025] The water inlet end cap is provided with a water inlet insert, which is inserted into the heating tube. A water inlet sealing ring is provided between the water inlet insert and the heating tube for sealing. The heating tube is inserted into the inlet of the water outlet end cap, and a water outlet sealing ring is provided between the water outlet end cap and the heating tube for sealing.

[0026] In this technical solution, the insertion structure of the water inlet end cap and the water outlet end cap with the heating tube helps to reduce assembly complexity. The installation design of the water inlet sealing ring and the water outlet sealing ring provides reliable sealing performance and prevents liquid leakage at both ends of the heating tube.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0058] In the embodiments of this application, reference is made to Figures 1 to 7 As shown, a liquid heating integrated component is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0059] like Figures 1 to 4 As shown, the liquid heating integrated assembly includes an upper housing 1, a lower housing 2, a heating tube 3, a water inlet cap 4, and a water outlet cap 5. The upper housing 1 and the lower housing 2 cooperate to form a protective cavity 6 surrounding the heating tube 3. Both ends of the protective cavity 6 are provided with clearance openings 61. The two ends of the heating tube 3 are respectively connected to the water inlet cap 4 and the water outlet cap 5 through the clearance openings 61. The water inlet cap 4 is provided with a water inlet channel 41 for water to enter the heating tube 3, and the water outlet cap 5 is provided with a water outlet channel 51 for water to exit the heating tube 3. The two ends of the upper housing 1 are fixedly connected to the water inlet cap 4 and the water outlet cap 5, and the two ends of the lower housing 2 are fixedly connected to the water inlet cap 4 and the water outlet cap 5, so that the heating tube 3, the water inlet cap 4, the water outlet cap 5, the upper housing 1, and the lower housing 2 form a fixed integrated structure.

[0060] Specifically, semi-circular grooves can be provided at both ends of the upper housing 1 and the lower housing 2. After the upper housing 1 and the lower housing 2 are fitted together, the semi-circular grooves at the same end of the upper housing 1 and the lower housing 2 fit together to form a circular clearance opening 61. The water inlet cap 4 is connected to the end of the heating pipe 3 for water inlet through the clearance opening 61 at one end, and the water outlet cap 5 is connected to the end of the heating pipe 3 for water outlet through the clearance opening 61 at the other end. When water heating is required, an external water source supplies water to the heating pipe 3 through the water inlet channel 41 of the water inlet cap 4. After the water is heated by the heating pipe 3, it is discharged through the water outlet channel 51 of the water outlet cap 5. To improve safety during use, such as... Figure 1 and Figure 2 As shown, a manual reset thermostat 7 and a self-reset thermostat 8 for monitoring the temperature of the heating element 3 can be installed on the upper housing 1 or the lower housing 2, forming a dual safety protection strategy. When the temperature of the heating element 3 exceeds the safety threshold (e.g., it can be set to 110℃-130℃), the manual reset thermostat 7 permanently disconnects the circuit, and power can only be restored by manually pressing the reset button (releasing the mechanical lock). For example, if the water tank of the water purifier is empty, and the heating element 3 continues to work, the temperature may suddenly rise to 120℃, causing the manual reset thermostat 7 to trip and lock, requiring manual reset after maintenance. When the temperature briefly exceeds the limit (e.g., it can be set to 90℃-100℃), the self-reset thermostat 8 disconnects the circuit and automatically restores power after the temperature drops. For example, if the water flow of the water purifier suddenly decreases, and the surface temperature of the heating element 3 rises to 95℃, the self-reset thermostat 8 disconnects the circuit, and heating automatically resumes after the water temperature drops to 70℃.

[0061] In this application, the heating tube 3 is surrounded by a protective cavity 6 formed by the upper shell 1 and the lower shell 2, and the inlet cap 4 and outlet cap 5 at both ends are fixedly connected. This achieves an integrated assembly design of the heating tube 3, upper shell 1, lower shell 2, inlet cap 4, and outlet cap 5. This not only protects the heating tube 3 from external impacts and environmental influences and provides heat insulation, but also facilitates overall installation and maintenance. When this component is installed on an external structure (such as the body support of a water purifier), it also helps to save on support structure. For example, only structures that cooperate with the external structure need to be set on the upper shell 1 and lower shell 2, so that the inlet cap 4 and outlet cap 5 can be stably installed simultaneously through a linkage effect while the upper shell 1 and lower shell 2 are stably installed on the external structure; or, only structures that cooperate with the external structure need to be set on the inlet cap 4 and outlet cap 5, so that the upper shell 1 and lower shell 2 can be stably installed simultaneously through a linkage effect while the inlet cap 4 and outlet cap 5 are stably installed on the external structure. In particular, for operating conditions involving water pump vibration, connecting them into a single structure helps improve vibration resistance and ensure long-term stability. This integrated assembly structure also improves the reliability of the connection between the inlet cap 4 and the outlet cap 5 and the heating pipe 3, as well as the sealing of the water circuit, reducing the risk of leakage. This application does not specifically limit the method of fixed connection, but a detachable fixed connection is preferred for ease of maintenance and repair.

[0062] As a preferred embodiment of this application, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, both ends of the upper housing 1 and the lower housing 2 are provided with outwardly extending connecting pieces 9. The water inlet cap 4 and the water outlet cap 5 are provided with connecting parts 10. The connecting pieces 9 and the connecting parts 10 are provided with corresponding through holes, and are fixedly connected by fasteners passing through the through holes of the connecting pieces 9 and the connecting parts 10. In this embodiment, the corresponding fit between the connecting pieces 9 and the through holes of the connecting parts 10, and the through connection by fasteners, realizes a detachable fixing method, which facilitates the assembly and disassembly of the components and allows for maintenance or replacement without damaging the components, thereby improving the maintainability and service life of the product. Specifically, the fasteners can be screws or bolt-nut assemblies. Taking screws as an example, during assembly, after aligning the connecting pieces 9 of the upper housing 1 and the lower housing 2 with the corresponding connecting parts 10, the screw is fixed by passing through the through holes of the connecting pieces 9 and the connecting parts 10.

[0063] In a preferred embodiment, such as Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, the connecting part 10 is provided with a clamping groove 101. The connecting pieces 9 at the same end of the upper housing 1 and the lower housing 2 are stacked and clamped in the clamping groove 101 by the connecting part 10. In this embodiment, the clamping groove 101 structure of the connecting part 10 clamps the connecting pieces 9 that can stack the upper housing 1 and the lower housing 2 together. After clamping, it is fixed by fasteners, which increases the connection area and stability, effectively disperses the fastening force, and avoids structural damage caused by local stress concentration. At the same time, the limiting function of the clamping groove 101 can prevent the upper housing 1 and the lower housing 2 from relative displacement during use, improve the anti-loosening ability of the fasteners, and help ensure the integrity of the protective cavity 6. In addition, stacking the connecting pieces 9 of the upper housing 1 and the lower housing 2 together helps the edges of the upper housing 1 and the lower housing 2 to fit tightly, improving the integrity and protective effect of the protective cavity 6. In addition, as an alternative embodiment, the clamping groove 101 design can be omitted, and the connecting pieces 9 of the upper housing 1 and the lower housing 2 can be connected to the two ends of the connecting part 10 respectively.

[0064] More preferably, the inlet cap 4 and the outlet cap 5 are respectively fitted into the heating pipe 3 along the axial direction of the heating pipe 3. The clamping groove 101 has an opening along the axial direction of the heating pipe 3, and the edge of the opening of the clamping groove 101 has a guide slope 102, which guides the connecting piece 9 into the clamping groove 101. The design of the axial opening of the clamping groove 101 and the guide slope 102 allows the connecting piece 9 to slide smoothly into the clamping groove 101 simultaneously during the docking of the inlet cap 4 and the outlet cap 5 with the heating pipe 3, saving assembly steps and reducing assembly difficulty and time cost. The guiding effect of the guide slope 102 also avoids hard collision between the connecting piece 9 and the edge of the clamping groove 101, simplifying the assembly operation, reducing the alignment difficulty, and reducing the risk of damage during the assembly process.

[0065] More preferably, such as Figure 4 and Figure 5 As shown, connecting pieces 9 are located at the edges of the upper housing 1 and the lower housing 2, with at least two connecting pieces 9 on the same end of both the upper housing 1 and the lower housing 2. The figure shows connecting pieces 9 on both sides of one end of the upper housing 1 and on both sides of the other end. The connecting pieces 9 on the same side of the upper housing 1 can be arranged independently or connected as a single unit. Correspondingly, connecting pieces 9 are provided on both sides of one end of the lower housing 2 and on both sides of the other end. The connecting pieces 9 on the same side of the lower housing 2 can be arranged independently or connected as a single unit. To accommodate the structures of the upper housing 1 and the lower housing 2, a connecting part 10 is also provided on both sides of the water inlet cap 4 and on both sides of the water outlet cap 5. By providing multiple connecting pieces 9 on both the upper housing 1 and the lower housing 2, a multi-point fixing structure is formed, enhancing the component's resistance to deformation under stress, especially suitable for liquid flow or vibration environments, ensuring the long-term stability of the connections between components.

[0066] As a preferred embodiment of this application, such as Figure 4 and Figure 5 As shown, both the upper housing 1 and the lower housing 2 are provided with outwardly extending mounting pieces 20. Each mounting piece 20 has a mounting hole 201. The mounting pieces 20 of the upper housing 1 and the lower housing 2 are stacked and mounted to the external structure through the mounting holes 201. When installing the liquid heating integrated assembly onto the external structure after its own assembly, fasteners such as screws can pass through the mounting holes 201 and connect to the external structure, ensuring installation stability. This design allows the assembly to be quickly positioned and fixed as a whole, while distributing installation stress and avoiding structural damage caused by excessive local stress. The mounting pieces 20 and connecting pieces 9 can be set together at the edges of the upper housing 1 and the lower housing 2. The mounting pieces 20 and connecting pieces 9 can be arranged independently, or, to improve assembly and installation stability, they can be connected as a single unit. Figure 5 The example shown is an embodiment in which the mounting piece 20 and the connecting piece 9 on one side are set independently, while the mounting piece 20 and the connecting piece 9 on the other side are connected as one unit.

[0067] As a preferred embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the inlet end cover 4 has a water pump mounting position 42 and an inlet pipe 43. A water pump 30 is mounted on the water pump mounting position 42. The outlet port of the water pump 30 is connected to the inlet channel 41, and the inlet pipe 43 is connected to the inlet port of the water pump 30. Specifically, the inlet channel 41 and the inlet pipe 43 can pass through the water pump mounting position 42. After the water pump 30 is fixed to the water pump mounting position 42, the inlet pipe 43 is connected to the inlet port of the water pump 30, and the outlet port of the water pump 30 is connected to the inlet end of the inlet channel 41. When the water pump 30 is working, water is drawn from the outside through the inlet pipe 43, flows through the inlet channel 41, and enters the heating tube 3. The integrated design of the water pump 30 and the inlet end cover 4 further improves the integration of the components and shortens the water flow path between the water pump 30 and the heating tube 3, reducing energy loss and leakage points. The water pump 30 is directly connected to the water inlet channel 41, which improves the efficiency of liquid delivery and makes the overall structure more compact, saving installation space.

[0068] In a preferred embodiment, such as Figure 6 As shown, the water pump mounting position 42 has multiple positioning holes 44 that pass through both ends of the water inlet end cover 4. Fasteners pass through the positioning holes 44 and are fixedly connected to the water pump 30. The heating tube 3 and the water pump 30 are located on the same side of the water inlet end cover 4. The cooperation between the positioning holes 44 and the fasteners (such as screws) ensures the accurate installation of the water pump 30 and the water inlet end cover 4. The design of the heating tube 3 and the water pump 30 being on the same side helps to reduce redundant space and make the component structure more compact.

[0069] As a preferred embodiment of this application, such as Figure 1 and Figure 2 As shown, the inlet end cap 4 is equipped with an inlet water temperature sensor 40 and a flow rate sensor 50, which are used to detect the water temperature and flow rate of the water entering the heating element 3, respectively; the outlet end cap 5 is equipped with an outlet water temperature sensor 60, which is used to detect the water temperature exiting the heating element 3. For example, the inlet water temperature sensor 40 and the outlet water temperature sensor 60 can be thermometers with temperature-sensing probes, and the flow rate sensor 50 can be a flow meter. The temperature-sensing probe of the inlet water temperature sensor 40 extends into the inlet flow channel 41, and the temperature-sensing probe of the outlet water temperature sensor 60 extends into the outlet flow channel 51. The inlet water temperature sensor 40 and the outlet water temperature sensor 60 can monitor the inlet water temperature and the outlet water temperature in real time, respectively, and the flow rate sensor 50 can monitor the water flow rate in real time, which facilitates temperature and flow control and reduces the risk of dry burning, overheating, or underheating.

[0070] As a preferred embodiment of this application, such as Figure 2 , Figure 3 and Figure 6 As shown, the water inlet cap 4 is equipped with a water inlet sleeve 45, which is inserted into the heating tube 3. A water inlet sealing ring 70 is provided between the water inlet sleeve 45 and the heating tube 3 for sealing. The heating tube 3 is inserted into the inlet of the water outlet cap 5, and a water outlet sealing ring 80 is provided between the water outlet cap 5 and the heating tube 3 for sealing. The insertion structure of the water inlet cap 4 and the water outlet cap 5 into the heating tube 3 helps to reduce assembly complexity. The installation design of the water inlet sealing ring 70 and the water outlet sealing ring 80 provides reliable sealing performance, preventing liquid leakage at both ends of the heating tube 3. Preferably, the water inlet sealing ring 70 and the water outlet sealing ring 80 can be made of silicone.

[0071] The following describes the installation method of a specific embodiment of the liquid heating integrated component of this application. This embodiment is not intended to limit the installation method of the component, and other suitable installation methods may be used in addition to this embodiment:

[0072] Component assembly: First, align and stack the connecting pieces 9 of the upper housing 1 and lower housing 2 so that the upper housing 1 and lower housing 2 surround the heating tube 3. Then, insert both ends of the heating tube 3 into the inlet sleeve 45 of the inlet end cap 4 and the inlet of the outlet end cap 5, respectively. Install the inlet sealing ring 70 between the inlet sleeve 45 and the heating tube 3, and install the outlet sealing ring 80 between the outlet end cap 5 and the heating tube 3. During insertion, the connecting piece 9 enters the clamping groove 101 through the guide slope 102. After aligning the connecting piece 9 with the through hole on the connecting part 10, use fasteners (such as screws) to pass through the through hole and fix them together to form an integrated whole structure.

[0073] Water pump 30 installation: Install water pump 30 on water pump mounting position 42 of water inlet end cover 4, connect water outlet port of water pump 30 to water inlet channel 41, and connect water inlet pipe 43 to water inlet port of water pump 30. Fix water pump 30 to water inlet end cover 4 by fasteners passing through positioning holes 44 on water pump mounting position 42, ensuring that water pump 30 and heating pipe 3 are located on the same side of water inlet end cover 4.

[0074] Installation of detection components: Install inlet water temperature detection component 40 and flow detection component 50 on inlet end cap 4, and install outlet water temperature detection component 60 on outlet end cap 5, so as to detect the temperature of inlet and outlet water and the flow rate of inlet water in real time, and provide data support for temperature control and flow regulation.

[0075] Overall installation: After the components are assembled as a whole, the mounting plates 20 on the upper shell 1 and the lower shell 2 are stacked.
