Description

Technical Field

[0001] This utility model relates to the field of electric water heater technology, and in particular to an aerator and an electric water heater. Background Technology

[0002] Existing electric water heater technology has achieved relatively complete and comprehensive development in terms of comfort, intelligence, and safety. Through continuous exploration, functional technologies are gradually being applied to bathing. Sparkling water is one such example. Compared to ordinary electric water heaters, those with nano-sparkling water functionality can better clean skin, clothing, and fruits and vegetables. The working principle of the aerator is that the sparkling water effectively reduces impurities by bursting and adsorbing bubbles, providing users with a better bathing experience.

[0003] However, current foaming devices often have limitations in their application scenarios.

[0004] Therefore, there is an urgent need for an aerator and an electric water heater to solve the above problems. Utility Model Content

[0005] One of the technical problems solved by this utility model is to provide a foaming device that can effectively improve the problem of limited application scenarios for foaming devices.

[0012] The foaming device described in this utility model has the following advantages compared with the prior art:

[0013] This invention features a Venturi tube and a hydrocyclone arranged sequentially along the liquid flow direction. By placing the Venturi tube at the water inlet of the bubble-forming shell, and narrowing the cross-section of the water flow in the middle section of the Venturi tube, according to the Venturi principle, increased flow velocity leads to decreased pressure, reducing the solubility of gas in water and causing it to detach from the water to form nanoscale bubbles. The faster the flow velocity, the better the bubble formation effect. A hydrocyclone is placed at the water outlet of the bubble-forming shell; the swirling blades break up the bubbles, thus forming bubbly water at the outlet after the liquid flows through the bubble-forming device. Specifically, the Venturi tube is integrated with the bubble-forming shell, reducing the number of parts in the bubble-forming device; it also simplifies the assembly process, making installation more convenient. Furthermore, the hydrocyclone is detachably mounted in the mounting groove, allowing for the selection of different models and quantities of hydrocyclones to meet various application needs, thus making the bubble-forming device suitable for multiple scenarios. In addition, by detachably installing adapters at both ends of the foaming shell, the foaming shell can be installed on different pipes by installing or replacing adapters of the appropriate size, thereby improving the practicality of the bubble device.

[0014] In one embodiment, the foaming shell is cylindrical, and the outer wall of the foaming shell is provided with a planar groove.

[0015] In one embodiment, there are multiple planar grooves, which are symmetrically arranged circumferentially along the outer wall of the foaming shell.

[0016] In one embodiment, the foaming device is provided with a plurality of cyclones, which are arranged sequentially along the axial direction of the foaming shell.

[0017] In one embodiment, the hydrocyclone has a connecting protrusion at one axial end and a connecting groove at the other end, the connecting protrusion being able to be placed within the connecting groove of an adjacent hydrocyclone.

[0018] In one embodiment, the adapter includes an inlet connector and an outlet connector, the inlet connector being threadedly connected to the inlet end of the foaming shell; the outlet connector being threadedly connected to the outlet end of the foaming shell.

[0019] In one embodiment, a gasket is provided between the water inlet end of the foaming shell and the water inlet connector; a gasket is provided between the water outlet end of the foaming shell and the water outlet connector.

[0020] In one embodiment, one of the inner wall of the mounting groove and the cyclone separator is provided with a positioning protrusion, and the other is provided with a positioning groove, wherein the positioning protrusion can be placed in the positioning groove.

[0021] In one embodiment, a transition groove is provided between the end face of the water inlet of the foaming shell and the venturi tube, and the venturi tube is connected to the bottom of the transition groove.

[0022] The second technical problem mentioned above is solved by the following technical solution:

[0023] An electric water heater includes an aerator as described in any of the above embodiments.

[0024] Compared with the prior art, the electric water heater described in this utility model has the following beneficial effects:

[0025] This utility model of an electric water heater is equipped with an aerator, offering more functions. Through the principle of bubble bursting and adsorption, it can better clean skin, clothing, and fruits and vegetables, effectively reducing impurities and providing users with a better bathing experience.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] like Figures 1-3 As shown, this embodiment provides a foaming device, which includes a foaming shell 100 and a hydrocyclone 200. The water inlet 101 of the foaming shell 100 is integrally provided with a Venturi tube 110, and the water outlet 102 of the foaming shell 100 is provided with a mounting groove 120. The hydrocyclone 200 is disposed in the mounting groove 120, and the liquid can flow through the Venturi tube 110 and the hydrocyclone 200 in sequence. Both ends of the foaming shell 100 can be detachably installed with adapters.

[0039] The foaming device is equipped with a Venturi tube 110 and a hydrocyclone 200 arranged sequentially along the liquid flow direction. Adaptors are connected to both ends of the foaming shell 100 for easy installation on a pipeline. By placing the Venturi tube 110 at the water inlet 101 of the foaming shell 100, and by narrowing the cross-section of the water flow in the middle section of the Venturi tube 110, according to the Venturi principle, increased flow velocity leads to decreased pressure, reducing the solubility of gas in water and causing it to detach from the water to form nanoscale bubbles. The faster the flow velocity, the better the bubble formation effect. By placing the hydrocyclone 200 at the water outlet 102 of the foaming shell 100, the swirling blades break up the bubbles, thus forming bubbly water at the outlet 102 after the liquid flows through the foaming device. Specifically, the Venturi tube 110 is integrally formed with the foaming shell 100, reducing the number of parts in the foaming device; furthermore, it simplifies the assembly process and makes installation more convenient. It is worth noting that by integrally integrating the Venturi tube 110 with the bubbler housing 100, and by providing a mounting groove 120 for the hydrocyclone 200 within the bubbler housing 100, liquid leakage between the Venturi tube 110 and the hydrocyclone 200 is effectively prevented, thus improving the sealing performance of the bubbler device. Furthermore, the detachable mounting of the hydrocyclone 200 within the mounting groove 120 allows for the selection of different models and quantities of hydrocyclones 200 to meet various application needs, expanding the applicability of the bubbler device. Additionally, the detachable adapters at both ends of the bubbler housing 100 allow for installation on different pipelines by installing or replacing adapters of suitable sizes, further enhancing the practicality of the bubbler device.

[0040] Preferably, multiple adapters can be provided, and the ends of different adapters away from the foam housing 100 have different sizes to adapt to pipes of different sizes.

[0041] In this embodiment, the foaming shell 100 is cylindrical. To facilitate the installation and disassembly of the foaming device, a flat groove 130 is provided on the outer wall of the foaming shell 100. Operators can use tools such as wrenches to engage with the flat groove 130 to easily clamp and tighten during installation and disassembly, thereby enabling the installation and disassembly of the foaming device. Exemplarily, the installation structure includes two flat grooves 130 provided on the outer wall of the foaming shell 100 and symmetrically arranged circumferentially, facilitating the use of tools.

[0042] Optionally, there are multiple planar grooves 130, which are symmetrically arranged circumferentially along the outer wall of the foam shell 100. This improves the reliability of the clamping between the tool and the outer wall of the foam shell 100. It is understood that two planar grooves 130 symmetrically arranged circumferentially on the outer wall of the foam shell 100 form a group for simultaneous engagement with the tool. Multiple groups are arranged circumferentially on the outer wall of the foam shell 100 to facilitate engagement with the tool at different installation angles. Additionally, multiple groups are also arranged radially on the outer wall of the foam shell 100 for engagement with the tool at different installation positions, allowing the operator to select the appropriate two planar grooves 130 for clamping during installation and removal.

[0043] Furthermore, the foaming device is equipped with multiple hydrocyclones 200, which are arranged sequentially along the axial direction of the foaming shell 100 to improve the effect of breaking up bubbles. In addition, by placing the hydrocyclones 200 within the mounting groove 120, additional connecting structures and parts are avoided, reducing the use of components and simplifying the structure, making the foaming device more compact and small.

[0044] Preferably, in order to achieve connection and positioning between multiple hydrocyclones 200, a connecting protrusion 210 is provided at one axial end of the hydrocyclone 200 and a connecting groove 220 is provided at the other end. When two adjacent hydrocyclones 200 are installed, the connecting protrusion 210 of one hydrocyclone 200 can be placed in the connecting groove 220 of the other hydrocyclone 200, thereby improving the connection accuracy between multiple hydrocyclones 200.

[0045] Optionally, to improve the circumferential positioning of the hydrocyclone 200 within the mounting groove 120, one of the inner wall of the mounting groove 120 and the hydrocyclone 200 is provided with a positioning protrusion, and the other is provided with a positioning groove. When the hydrocyclone 200 is placed in the mounting groove 120, the mounting protrusion is correspondingly placed in the positioning groove to prevent the hydrocyclone 200 from rotating within the mounting groove 120.

[0046] It is worth noting that the axial positioning of the hydrocyclone 200 can be achieved by abutting against the end of the venturi tube 110, or by setting a limiting protrusion in the mounting groove 120 that can abut against the end of the hydrocyclone 200. No specific limitation is made here.

[0047] In this embodiment, the adapter includes an inlet connector 310 and an outlet connector 320. The inlet connector 310 is threadedly connected to the inlet end 101 of the aerator housing 100 for connection and conduction with the front-end water supply device. The outlet connector 320 is threadedly connected to the outlet end 102 of the aerator housing 100 for connection and conduction with the water user. Correspondingly, both ends of the aerator housing 100 are provided with threaded structures to connect with the inlet structure and the outlet connector 320 respectively. Threaded connections are more reliable, have better sealing, and are easier to disassemble. Furthermore, the threads of the aerator device are all standard threads to improve the versatility of the aerator device. When applied to different water treatment or hot water products, only the corresponding threaded adapter needs to be replaced. When the aerator device is applied to an electric water heater, the inlet connector 310 can be connected to the outlet anti-electric shock wall of the electric water heater, and the outlet structure can be connected to the outlet pipe of the electric water heater.

[0048] For example, the inlet connector 310 has internal threads at both ends, one end being a G1 / 2 internal thread and the other end being a G7 / 8 internal thread. The outer side of the inlet connector 310 is also hexagonal for easy fastening during installation. Similarly, the outlet connector 320 also has internal threads at both ends, one end being a G1 / 2 internal thread and the other end being a G7 / 8 internal thread. The outer side of the outlet connector 320 is also hexagonal. It is understood that when the aerator is used in different devices, those skilled in the art can configure the thread type and parameters as needed, and no specific limitations are made here.

[0049] Preferably, a gasket 330 is provided between the water inlet end 101 and the water inlet connector 310 of the foaming shell 100; a gasket 330 is also provided between the water outlet end 102 and the water outlet connector 320 of the foaming shell 100. By providing the gasket 330, the sealing between the water inlet end 101 and the water inlet connector 310, and between the water outlet end 102 and the water outlet connector 320 of the foaming shell 100, is improved to prevent leakage and enhance the foaming effect. Optionally, the gasket 330 is a silicone gasket 330 for even better sealing and waterproofing.

[0050] Specifically, a transition groove 140 is provided between the end face of the water inlet 101 of the foaming shell 100 and the venturi tube 110. The venturi tube 110 is connected to the bottom of the transition groove 140. By providing the transition groove 140, a transition cavity is formed between the transition groove 140 and the water inlet. When the liquid enters the foaming shell 100 through the water inlet, it first enters the transition cavity and then enters the venturi tube 110, making the liquid distribution among the multiple pipes of the venturi tube 110 more uniform, thereby improving the foaming effect.

[0051] In this embodiment, the outer walls of the foaming shell 100, the water inlet connector 310, and the water outlet connector 320 are all provided with indicator arrows to indicate the flow direction of the liquid inside, making it easier for operators to perform assembly operations.

[0052] This embodiment also discloses an electric water heater, including the aerator described in any of the above embodiments. By incorporating the aforementioned aerator, the electric water heater gains more functionality. Through the principle of bubble bursting and adsorption, it can better clean skin, clothing, and fruits and vegetables, effectively reducing impurity residue and providing users with a better bathing experience. Furthermore, the aerator has fewer parts, making assembly more convenient and enhancing the market competitiveness of the electric water heater.

[0053] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0054] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
