Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically providing an instant heating component and a water treatment device having the same. Background Technology

[0002] With the continuous improvement of living standards, people's demands for quality of life are increasing, and the need for instant hot water is becoming more and more common. Water treatment equipment with instant heating functions, such as instant water dispensers, instant water purifiers, instant tea makers, instant electric kettles, instant hot water faucets, and instant showers, have been widely used in modern homes due to their significant advantage of "instant hot water." The core heating element of water treatment equipment with instant heating functions is the instant heating component, whose performance directly determines the heating efficiency, safety, and user experience of the water treatment equipment.

[0003] like Figure 1 As shown, existing instant heating components typically include a heating tube 2, a heating element, and two guide end caps 3. The heating element is located outside the heating tube 2. The two guide end caps 3 are connected to the inlet pipe and the outlet pipe, respectively, and the ends of the guide end caps 3 are inserted into both ends of the heating tube 2. Water flows into the heating tube 2 from the inlet pipe, is heated by the heating element, and then flows out from the outlet pipe. A cap-shaped sealing ring 6 is fitted onto the end of the guide end cap 3. The silicone cap-shaped sealing ring 6 fits snugly against the inner wall of the heating tube 2, sealing the connection between the heating tube 2 and the guide end cap 3 to prevent water leakage from the heating tube 2. To improve the sealing effect and facilitate assembly, the cap-shaped sealing ring 6 completely covers the end of the guide end cap 3, resulting in a relatively large size for the cap-shaped sealing ring 6.

[0004] However, in a long-term hot water environment, silicone or rubber cap-shaped sealing rings are prone to producing odors. Because the cap-shaped sealing rings are relatively large, their contact area with the water inside the heating tube is large, making it easier for the water to produce odors. In addition, the large size means that a large amount of silicone is used in the cap-shaped sealing rings, which increases the cost of instantaneous heating components.

[0005] Accordingly, there is a need in the art for a new instant heating component and a water treatment device having it to solve the above problems. Utility Model Content

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that silicone or rubber cap-shaped sealing rings are prone to producing odors in long-term hot water environments. Because the cap-shaped sealing rings are large in size, their contact area with the water in the heating tube is large, making it easier for the water to produce odors. In addition, the large size requires a large amount of silicone for the cap-shaped sealing rings, which increases the cost of the instantaneous heating components.

[0007] In a first aspect, the present invention provides an instant heating assembly; the instant heating assembly includes a heating tube, two flow guide end caps and a sealing assembly, wherein the two flow guide end caps are respectively inserted into both ends of the heating tube and connected to the water circuit of a water treatment device, and the sealing assembly seals between the flow guide end caps and the inner wall of the heating tube; The flow guide end cap includes a water inlet pipe and a connector pipe that are interconnected. The water inlet pipe is connected to the water circuit of the water treatment equipment, and the connector pipe is inserted into the end of the heating pipe. The sealing assembly includes at least one O-ring, which is fitted onto the insertion tube; When multiple O-rings are provided, the number of O-rings = the length L of the insertion tube / (the diameter D + A mm of the O-ring), rounded down, where A is a constant and 4 ≤ A ≤ 6.

[0008] When using the above technical solution, the water inlet of the instant heating element enters the heating tube through the water inlet pipe and connector of one of the guide end caps, and then flows out through the connector and water inlet pipe of the other guide end cap. An O-ring seals the gap between the connector and the heating tube, reducing the possibility of leakage. When the heating tube and connector are of the same size, using a single O-ring results in a smaller water-contact area and material consumption compared to a cap-type O-ring. When multiple O-rings are used, the number is determined based on the relationship between the connector length, the seal diameter, and a constant A. This allows the instant heating element to achieve a good sealing effect with fewer O-rings. Furthermore, since A is a constant between 4 and 6 (meaning the distance between two adjacent seals is 4mm-6mm), the total water-contact area and total material consumption of multiple O-rings are less than that of a cap-type O-ring. The total water-contact area of ​​a single O-ring or multiple O-rings is smaller than that of a cap-shaped O-ring, which can reduce the possibility of hot water producing odors and improve the effluent quality of water treatment equipment. At the same time, the total material consumption of a single O-ring or multiple O-rings is less than that of a cap-shaped O-ring, which can reduce the cost of instant heating components, thereby reducing the cost of water treatment equipment.

[0009] In the preferred embodiment of the above-mentioned instant heating component, the end of the heating tube is provided as an inclined surface, and the inclined surface gradually tapers from the outer wall to the inner wall of the heating tube.

[0010] By adopting the above technical solution, setting the end of the heating tube as an inclined surface can reduce the possibility of the heating tube end tearing the O-ring seal and improve the yield.

[0011] In the preferred embodiment of the above-mentioned instant heating component, the angle between the inclined surface and the axis of the heating tube is α, where 40°≤α≤50°.

[0012] When the above technical solution is adopted, the angle between the inclined surface and the axis of the heating tube is set to 40°-50°. When the insertion tube is installed into the heating tube, the end of the heating tube can be reduced from tearing the O-ring seal, thus improving the yield.

[0013] In the preferred embodiment of the above-mentioned instant heating component, the water inlet pipe is provided with at least one snap-fit ​​groove, and the O-ring is disposed in the snap-fit ​​groove and fits against the inner wall of the heating pipe.

[0014] When the above technical solution is adopted, the O-ring is limited by the snap-fit ​​groove, which reduces the possibility of displacement of the O-ring and reduction of sealing effect.

[0015] In the preferred embodiment of the above-mentioned instant heating component, at least one limiting protrusion is provided on the inner wall of the O-ring seal, and at least one limiting groove is provided at the bottom of the snap-fit ​​groove, with the limiting protrusion inserted into the limiting groove.

[0016] By adopting the above technical solution, the O-ring is further limited by the cooperation of the limiting protrusion and the limiting groove, so that the O-ring can seal the gap more stably.

[0017] In the preferred embodiment of the above-mentioned instant heating component, the limiting protrusion is hemispherical, the limiting groove is hemispherical and matches the shape of the limiting protrusion, or the limiting groove is annular and the limiting protrusion is inserted into the limiting groove.

[0018] When the above technical solution is adopted, the hemispherical limiting protrusion is inserted into the annular limiting groove, which can better limit the displacement of the O-ring in the axial direction of the insertion pipe and facilitate assembly.

[0019] The hemispherical limiting protrusion is inserted into the hemispherical limiting groove, which can better limit the displacement of the O-ring in the axial direction of the insertion tube, and can also limit the displacement of the O-ring in the direction perpendicular to the axial direction of the insertion tube.

[0020] In the preferred embodiment of the above-mentioned instant heating component, the insertion tube is provided with a first positioning mark, and the limiting protrusion is provided with a second positioning mark. When the first positioning mark and the second positioning mark are aligned, the limiting protrusion is aligned with the limiting groove.

[0021] When using the above technical solution, during assembly, first align the first positioning mark with the second mark so that the limiting protrusion is aligned with the limiting groove, and then assemble the O-ring into the snap-fit ​​groove so that the limiting protrusion can be inserted into the limiting groove more accurately, thereby improving assembly efficiency.

[0022] In the preferred embodiment of the above-mentioned instant heating component, the height of the limiting protrusion is 1 / 5 of the diameter of the O-ring seal.

[0023] When the above technical solution is adopted, the height of the limiting protrusion is set to 1 / 5 of the diameter of the sealing ring. This height has a good limiting effect on the O-ring, has a small impact on the assembly efficiency of the O-ring, and also increases the amount of material used by a small amount.

[0024] In the preferred embodiment of the above-mentioned instant heating component, the instant heating component further includes a housing, the housing has mounting ports at both ends, and the heating tube is located inside the housing; The guide end cap also includes a cover, on which the water inlet pipe and the insertion pipe are both located. The cover closes the installation port and is located on the housing.

[0025] By adopting the above technical solution, the sealing of the installation port and the installation of the heating tube are achieved by connecting the cover to the shell.

[0026] Secondly, the present invention also provides a water treatment device; the water treatment device includes the instantaneous heating component as described above.

[0027] When the above technical solution is adopted, with the same size heating pipe and connector, the total water immersion area of ​​a single O-ring or multiple O-rings is smaller than that of a cap-shaped seal, which can reduce the possibility of hot water producing odor and improve the effluent quality of the water treatment equipment; at the same time, the total material consumption of a single O-ring or multiple O-rings is smaller than that of a cap-shaped seal, which can reduce the cost of the instant heating component, thereby reducing the cost of the water treatment equipment.

[0028] In summary, this utility model has at least the following beneficial effects: 1. When the heating element and connector are of the same size, and multiple O-rings are used, the number of O-rings is determined based on the relationship between the connector length, the diameter of the O-ring, and a constant A. This allows the instantaneous heating element to achieve a good sealing effect with fewer O-rings. Furthermore, since A is a constant between 4 and 6 (meaning the distance between two adjacent O-rings is 4mm-6mm), the total water-contact area and total material consumption of multiple O-rings are less than those of cap-type O-rings. A smaller total water-contact area for a single or multiple O-rings compared to a cap-type O-ring reduces the likelihood of odors from the hot water and improves the quality of the effluent from the water treatment equipment. Simultaneously, the lower total material consumption of a single or multiple O-rings compared to a cap-type O-ring reduces the cost of the instantaneous heating element, thereby reducing the cost of the water treatment equipment. 2. Setting the end of the heating tube as an inclined surface, preferably at 40°-50°, can reduce the chance of the end of the heating tube tearing the O-ring seal when the insertion tube is installed into the heating tube, thereby improving the yield rate. 3. By using the snap-fit ​​groove to engage with the O-ring and the limiting protrusion to engage with the limiting groove, the possibility of displacement of the O-ring that reduces the sealing effect is reduced.

[0031] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0032] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," and "right," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] To address the issue that existing instant heating elements in hot water environments are prone to developing odors due to the silicone cap-shaped sealing rings, which are large in size and have a large contact area with the water inside the heating element, making it easier for the water to develop odors; furthermore, the large size requires a large amount of silicone for the cap-shaped sealing rings, increasing the cost of the instant heating elements.

[0035] like Figures 2 to 5 As shown in the illustration, this embodiment discloses a water treatment device. The water treatment device can be a water dispenser, a water purifier / heater, a water heater, a kettle, a tea maker, a coffee machine, etc. In practical applications, this invention does not limit the specific type of water treatment device. In this embodiment, a water purifier is used as an example. The water purifier includes a purified water tank, a water pump, an instant heating element, and a water outlet component. An inlet pipe connects the purified water tank to the instant heating element, and an outlet pipe connects the instant heating element to the water outlet component. The water pump is installed on the inlet pipe and supplies water from the purified water tank into the instant heating element for heating. The water then flows out through the outlet pipe and the water outlet component for the user to drink.

[0036] Specifically, the instant heating assembly includes a housing 1, a heating tube 2, a heating element (not shown in the figure), two flow guide end caps 3, and a sealing assembly. The heating element is located outside the heating tube 2 and is used to heat the heating tube 2 to heat the water flowing through it. The heating element can be a heating resistor sprayed on the heating tube 2, or an electromagnetic heating coil wound around the outside of the heating tube 2, etc., with no specific limitations. Both ends of the housing 1 have mounting ports. The heating tube 2 extends into the housing 1 through the mounting ports. The two flow guide end caps 3 are respectively inserted into both ends of the heating tube 2 and close the corresponding mounting ports. The flow guide end caps 3 are connected to the housing 1 to install the heating tube 2. One flow guide end cap 3 is connected to the water inlet pipe, and the other flow guide end cap 3 is connected to the water outlet pipe. The sealing assembly seals between the flow guide end cap 3 and the inner wall of the heating tube 2 to reduce the possibility of water leakage from the heating tube 2. Water in the purified water tank flows through the inlet pipe, guide end cover 3, heating pipe 2, guide end cover 3 and outlet pipe to the water outlet component under the action of the water pump, and is supplied to the user for drinking. The water temperature rises during the flow through the heating pipe 2, realizing instant heating.

[0037] like Figure 2 and Figure 3 As shown, the guide end cap 3 includes a cover 31, a water inlet pipe 32 fixed on the cover 31, and a connector 33. The water inlet pipe 32 and the connector 33 are interconnected. The water inlet pipe 32 is connected to an inlet pipe or an outlet pipe. The connector 33 is inserted into the heating tube 2, and a sealing component seals between the connector 33 and the heating tube 2. Alternatively, the water inlet pipe 32 can be directly connected to the water tank or the outlet component, as long as the water to be heated can flow through the heating tube 2. After the connector 33 is inserted into the heating tube 2, the cover 31 closes the installation opening, and the cover 31 is connected to the housing 1 by multiple bolts to fix the heating tube 2.

[0038] The sealing assembly includes at least one O-ring 4, which is fitted onto the insertion pipe 33. The size of a single O-ring 4 is smaller than that of a cap-shaped sealing ring 6, so that the water contact area and material consumption of a single O-ring 4 are smaller than those of a cap-shaped sealing ring 6. This can reduce the possibility of hot water producing odor, improve the output water quality of the instantaneous heating unit, and also save material consumption and reduce costs.

[0039] When multiple O-rings 4 are used, the number of O-rings 4 is equal to the length L of the insertion tube 33 / (diameter D + A mm of the sealing ring), rounded down, where A is a constant and 4 ≤ A ≤ 6. When the heating tube 2 and insertion tube 33 have the same dimensions, the number of O-rings 4 is determined based on the relationship between the length of the insertion tube 33, the diameter of the sealing ring, and the constant A, so that the instantaneous heating assembly can achieve a good sealing effect with fewer O-rings 4. Furthermore, since A is a constant between 4 and 6, meaning the distance between two adjacent sealing rings is 4 mm to 6 mm, the total water-contact area and total material consumption of multiple O-rings 4 are less than that of the cap-type sealing ring 6. Preferably, A is 5; at this distance, both the sealing effect can be improved, and fewer O-rings 4 can be used.

[0040] The total water-contact area of ​​multiple O-rings 4 is smaller than that of cap-shaped seals 6, which can reduce the possibility of hot water producing odors and improve the effluent quality of water treatment equipment. At the same time, the total material usage of multiple O-rings 4 is smaller than that of cap-shaped seals 6, which can reduce the cost of instant heating components, thereby reducing the cost of water treatment equipment.

[0041] like Figure 2 and Figure 3 As shown, the water inlet pipe 32 is further provided with at least one snap-fit ​​groove 331, and the O-rings 4 are placed in the snap-fit ​​groove 331 one by one, fitting against the inner wall of the heating pipe 2. The snap-fit ​​groove 331 limits the position of the O-rings 4, reducing displacement and thus more stably sealing the gap between the heating pipe 2 and the connector 33, improving the sealing effect. In this embodiment, the snap-fit ​​groove 331 is designed as a ring shape to match the O-rings 4, further reducing its water-contact area and lowering the possibility of odor from the hot water.

[0042] In this embodiment, two O-rings 4 are fitted on the insertion tube 33, with a distance of 5mm between the two O-rings 4 and a diameter of 3mm. When the heating tube 2 and the insertion tube 33 are the same size, compared with the cap-shaped sealing ring 6, the water immersion area is reduced by 70%, which can reduce the possibility of water producing odor; the material usage is reduced by 60%, which can effectively reduce costs.

[0043] The end of the heating tube 2 is set as an inclined surface 21, which gradually tapers from the outer wall to the inner wall of the heating tube 2. Preferably, the angle between the inclined surface 21 and the axis of the heating tube 2 is α, 40°≤α≤50°. In this embodiment, α is 45°. When the insertion tube 33 is installed into the heating tube 2, the situation where the end of the heating tube 2 scratches the O-ring seal 4 can be reduced, thereby improving the yield.

[0044] like Figure 4 and Figure 5As shown, further, as another preferred embodiment, at least one limiting protrusion 41 is integrally formed on the inner wall of the O-ring 4, and the height h of the limiting protrusion 41 is 1 / 5 of the diameter of the sealing ring. The height of the limiting protrusion 41 refers to the distance between the connection point of the limiting protrusion 41 and the O-ring 4 and the farthest point of the limiting protrusion 41 from the O-ring 4. At least one limiting groove 332 is provided at the bottom of the snap-fit ​​groove 331, and the limiting protrusion 41 is inserted into the limiting groove 332. Through the cooperation of the limiting protrusion 41 and the limiting groove 332, the O-ring 4 is further limited, so that the O-ring 4 can more stably seal the gap. Moreover, setting the height of the limiting protrusion 41 to 1 / 5 of the diameter of the sealing ring can play a good limiting role for the O-ring 4, and the amount of material used is relatively small, so the impact on the cost is small. At the same time, the limiting protrusion 41 of this height is within the elastic range of the O-ring 4, so it has little impact on the assembly efficiency and assembly quality of the O-ring 4.

[0045] like Figure 4 and Figure 5 As shown, the limiting protrusion 41 can be one or more hemispheres, or it can be annular, rectangular, or other shapes. The limiting groove 332 can be a shape that matches the limiting protrusion 41. For example, if the limiting protrusion 41 is annular, the limiting groove 332 can also be a matching annular shape. Alternatively, if the limiting protrusion 41 is multiple hemispheres, the limiting groove 332 can be annular, so that multiple limiting protrusions 41 can be inserted into the limiting groove 332.

[0046] In this embodiment, the limiting protrusion 41 is described as a hemispherical shape, with four protrusions. The limiting groove 332 is a hemispherical shape that matches the limiting protrusion 41, which can limit the displacement of the O-ring 4 in the axial direction of the insertion tube 33 and in the direction perpendicular to the axial direction of the insertion tube 33, thereby improving the sealing effect of the O-ring 4. In order to improve the assembly efficiency of the O-ring 4, the insertion tube 33 is provided with a first positioning mark 5, and the limiting protrusion 41 is provided with a second positioning mark. The first positioning mark 5 and the second positioning mark can be a point or a line segment, and can be set on the limiting protrusion 41 and the insertion tube 33 by coating or engraving. When the first positioning mark 5 and the second positioning mark are aligned, the limiting protrusion 41 and the limiting groove 332 are aligned. Preferably, the first positioning mark 5 and the second positioning mark are line segments. The first positioning mark 5 is coated on the insertion tube 33, and the diameter of the first positioning mark 5 coincides with that of the limiting groove 332, which is parallel to the axis of the insertion tube 33. The second positioning mark is coated on the outer wall of the hemispherical limiting protrusion 41 and cooperates with the first positioning mark 5. During assembly, the first positioning mark 5 and the second mark are first aligned so that the limiting protrusion 41 and the limiting groove 332 are aligned. Then, the O-ring 4 is installed into the snap-fit ​​groove 331 so that the limiting protrusion 41 can be inserted into the limiting groove 332 more accurately, thereby improving assembly efficiency.

[0047] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
