False alarm prevention structure, hot tank assembly and water purification device

Abstract

The application relates to a false alarm prevention structure, a hot tank assembly and a pure drinking equipment, which comprises a cover body and mounting seats, at least two mounting seats are arranged on the cover body, and the adjacent two mounting seats are arranged at intervals, the at least two mounting seats are provided with access ports for arranging detection pieces, and the adjacent two access ports are located on different horizontal planes to limit the conduction between the adjacent two detection pieces. Thus, by arranging at least two mounting seats on the cover body, the detection pieces are inserted into the access ports of the mounting seats, and the access ports of the mounting seats are arranged on different horizontal planes. When water droplets are condensed on the cover body and the adjacent two mounting seats, the height difference between the adjacent mounting seats limits the water droplets from forming a channel between the access ports of the adjacent mounting seats, thereby ensuring that the detection pieces arranged on the adjacent mounting seats cannot form an electrical connection, so that the signal abnormal error of the detection pieces is effectively avoided.

Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to an anti-false alarm structure, a heating element assembly, and a water purification device. Background Technology

[0002] The heating element technology heats and stores water within the heating element assembly, releasing it when needed. While the heating element has a wide water flow range, the steam generated during heating can condense between the water level detectors, potentially causing electrical continuity and triggering alarms. For example, after refilling, a connection between the high and low water levels will cause an alarm. Additionally, during refilling, the water flow hitting the top cover may momentarily connect the water level detectors, also potentially leading to false alarms. Utility Model Content

[0003] Therefore, it is necessary to provide a false alarm prevention structure, heating element assembly, and water purification equipment to address the problem of false alarms that are prone to occur in current detection devices.

[0004] The first aspect of this application provides a false alarm prevention structure, including:

[0005] Cover; and

[0006] The mounting base includes at least two mounting bases, which are disposed on the cover and spaced apart from each other. Each mounting base has an inlet for mounting a detection element, and adjacent inlets are located on different horizontal planes to restrict communication between adjacent detection elements.

[0007] In one embodiment, the mounting base includes a base on which the access port is formed.

[0008] In one embodiment, the mounting base further includes a mounting protrusion disposed on the base, the access opening being formed on the mounting protrusion and extending to the base.

[0009] In one embodiment, in two adjacent mounting bases, the base of at least one mounting base forms a stepped structure with the mounting protrusion.

[0010] In one embodiment, the mounting base protrudes from the surface of the cover.

[0011] In one embodiment, the extension direction of the mounting base is perpendicular to the cover.

[0012] In one embodiment, the cover is provided with a water inlet and a baffle. The water inlet is used to supply water to the side where the detection element is located, and the baffle is located between the detection element and the water inlet to prevent water input from the water inlet from splashing onto the detection element.

[0013] In one embodiment, the baffle is arranged around the periphery of the inlet to form an annular baffle.

[0014] A second aspect of this application provides a heating element assembly for heating input water, comprising:

[0015] The heating element body includes a water storage cavity and an installation port, the water storage cavity being connected to the installation port; and

[0016] The false alarm prevention structure described in the first aspect of this application includes a cover disposed at the mounting opening, and each of the mounting seats disposed on the side of the cover facing the water storage cavity; and

[0017] The detection element is provided in at least two, and the at least two detection elements are respectively disposed on the mounting base and extend into the water storage cavity.

[0018] The third aspect of this application provides a water purification device that uses the heating element assembly described in the second aspect of this application.

[0019] In the aforementioned anti-false alarm structure, heating element assembly, and water purification device, at least two mounting seats are provided on the cover, with the two mounting seats spaced apart. The detection element is correspondingly installed at the inlet of the mounting seat, and the inlets of the mounting seats are set to be on different horizontal planes, i.e., there is a height difference between adjacent mounting seats. At this time, when water droplets condense on the cover and the two adjacent mounting seats, due to the height difference between the adjacent mounting seats, the condensed water droplets are difficult to form a path between the inlets of the adjacent mounting seats, thus preventing the detection elements on the mounting seats from forming an electrical connection. This effectively avoids the occurrence of abnormal signal error of the detection elements. Attached Figure Description

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] The heating element is a key component in water purifiers and water dispensers, where water is heated and stored. However, after water is added to the heating element, the heating element continues to heat the water. The water vapor generated by this heating may condense into water droplets between the detectors. These droplets can accumulate and connect the detectors, causing a short circuit and triggering an abnormal alarm. Additionally, during water replenishment, water may splash onto the surface of the cover where the detectors are mounted, potentially causing a momentary connection between the detectors and resulting in false alarms. To prevent abnormal alarms from the detectors, this application provides a false alarm prevention structure 10.

[0031] like Figure 1 and Figure 2 As shown, the false alarm prevention structure 10 includes a cover 11 and at least two mounting seats 12. The at least two mounting seats 12 are disposed on the cover 11, and the access ports 121 of two adjacent mounting seats 12 are on different horizontal planes, thereby preventing the formation of an electrical connection between the access ports 121 of adjacent mounting seats 12.

[0032] Therefore, by independently setting the detection element 22 on different mounting bases 12, and ensuring that the inlet 121 of the detection element 22 on adjacent mounting bases 12 is not on the same horizontal plane (i.e., there is a height difference H between the inlet 121 of the detection element 22 on adjacent mounting bases 12), if water droplets condense on the cover 11 and the mounting base 12, the water droplets condensed on the adjacent mounting bases 12 cannot spread along the mounting bases 12 to the inlet 121, thus preventing the inlet 121 of the adjacent mounting bases 12 from connecting and forming an electrical connection via the condensed water droplets. Therefore, this arrangement effectively prevents the detection elements 22 on adjacent mounting bases 12 from conducting, thereby avoiding false alarms due to abnormal signals from the detection element 22.

[0033] like Figure 3 As shown, to further ensure that no electrical connection is formed between the inlets 121 of adjacent mounting seats 12, the adjacent mounting seats 12 are spaced apart on the cover 11. This spaced arrangement further increases the distance between the adjacent mounting seats 12, thus preventing water droplets condensing on the adjacent mounting seats 12 from gathering and connecting to form an electrical connection when they are close together. Therefore, by spaced apart the adjacent mounting seats 12 and using inlets 121 with a height difference H, it is possible to further prevent malfunctions such as false alarms from the detection element 22.

[0034] like Figure 2As shown, the mounting base 12 has at least two forms. For example, the mounting base 12 may only include a base 122. Alternatively, the mounting base 12 may be a combination of a base 122 and a mounting protrusion 123. In this case, the mounting protrusion 123 may be coaxially disposed on the base 122, and an inlet 121 may be formed on the mounting protrusion 123 and extend to the base 122. The mounting protrusion 123 may be a protrusion with a radial dimension smaller than the radial dimension of the base 122. In this case, after the mounting protrusion 123 is mounted on the base 122, a stepped structure is formed between the mounting protrusion 123 and the base 122.

[0035] When installing the detection component 22, if the base 122 does not have a mounting protrusion 123, the detection component 22 can be directly installed in the access port 121 opened on the base 122. If the base 122 has a mounting protrusion 123, the detection component 22 can be installed in the access port 121 opened on the mounting protrusion 123.

[0036] In addition, in two adjacent mounting bases 12, the base 122 of at least one mounting base 12 and the inlet 121 are formed together in a stepped structure. The stepped structure can increase the difficulty of water droplets accumulating between the inlets 121 of adjacent mounting bases 12, thereby avoiding the connection between adjacent inlets 121 as much as possible.

[0037] In this embodiment, the length of the mounting base 12 includes the following two cases: if no mounting protrusion 123 is provided on the base 122, then the length represented by the mounting base 12 is only the length of the base 122. If the mounting protrusion 123 is provided on the base 122, then the length represented by the mounting base 12 is the sum of the length of the base 122 and the length of the mounting protrusion 123.

[0038] In this embodiment, the arrangement between adjacent mounting bases 12 is illustrated by example.

[0039] For example, if two mounting seats 12 are provided, and the connection points of the two mounting seats 12 and the cover 11 are set to be on the same horizontal plane, and both mounting seats 12 extend in the same direction, then the length of one mounting seat 12 is set to a (a can be the length of the base 122), and the length of the other mounting seat 12 is set to b (b can be the sum of the length of the base 122 and the length of the mounting protrusion 123), where a < b. Therefore, the arrangement of the lengths of two adjacent mounting seats 12 is ab, that is, the access points 121 of the two mounting seats 12 are on different horizontal planes.

[0040] If three mounting bases 12 are provided, the connection points of the three mounting bases 12 and the cover 11 are set to be on the same horizontal plane. The three mounting bases 12 extend in the same direction to form a straight line. The lengths of the first mounting base 12 and the third mounting base 12 are set to a, and the length of the second mounting base 12 is set to b, where a < b. Thus, the arrangement of the lengths of the three mounting bases 12 is aba, and the inlets 121 of the three mounting bases 12 are also on different horizontal planes.

[0041] If four mounting bases 12 are provided, the connection points of the four mounting bases 12 and the cover 11 are set to be on the same horizontal plane. The four mounting bases 12 extend in the same direction to form a straight line. The lengths of the first and third mounting bases 12 are set to a, and the lengths of the second and fourth mounting bases 12 are set to b, where a < b. Thus, the arrangement of the lengths of the four mounting bases 12 is abab, and the inlets 121 of the four mounting bases 12 are also on different horizontal planes.

[0042] Therefore, by analogy, five or more mounting seats 12 can also be provided on the cover 11. Furthermore, it should be noted that when three or more mounting seats 12 are provided, it is not limited to ensuring that the lengths of the mounting seats 12 are identical in pairs. For example, the length of the first mounting seat 12 can be set to 'a', the length of the second mounting seat 12 to 'b', and the length of the third mounting seat 12 to 'c', etc., where c ≠ a / b. Therefore, it is only necessary to ensure that the lengths of adjacent mounting seats 12 are different.

[0043] More specifically, in this embodiment, the multiple mounting seats 12 are arranged along a straight line on the cover 11. Of course, the multiple mounting seats 12 can be arranged in a staggered manner on the cover 11.

[0044] In an optional embodiment, the extension direction of the mounting base 12 is perpendicular to the cover 11. The mounting base 12, being perpendicular to the cover 11, ensures that after the detection element 22 is connected to the inlet 121, it can also be positioned perpendicular to the cover 11. The cover 11 typically covers the opening of the heating element assembly 20, which is the mounting port 212 of the heating element assembly 20. Therefore, the detection element 22, positioned perpendicular to the cover 11, can be vertically inserted into the water-filling space inside the heating element assembly 20 through the mounting port 212, thereby ensuring the accuracy of the water level measured by the detection element 22.

[0045] In an alternative embodiment, at least one mounting base 12 protrudes from the surface of the cover 11 such that its access port 121 is on a different horizontal plane from the surface of the cover 11.

[0046] In this embodiment, the surface of the cover 11 refers to the side facing the extension direction of the mounting base 12. After the mounting base 12 is placed on the cover 11, one end of the mounting base 12 is connected to the cover 11, and the other end is the inlet 121 of the detection element 22, and the inlet 121 is usually opened at the end away from the cover 11.

[0047] However, it should be noted that since the cover 11 has a certain thickness, when the end of the mounting base 12 connected to the cover 11 is embedded inside the cover 11, and the length of the mounting base 12 is equal to the thickness of the cover 11, the inlet 121 of the mounting base 12 is still flush with the surface of the cover 11. In this case, it is also possible that the inlet 121 of one of the mounting bases 12 is set below the surface of the cover 11, that is, the mounting base 12 is entirely embedded inside the cover 11. At this time, although the inlets 121 of adjacent mounting bases 12 are controlled to be on different horizontal planes, and the inlets 121 and the surface of the cover 11 are on different horizontal planes, water droplets condensed on the cover 11 and water droplets condensed on the mounting bases 12 may still accumulate and become conductive. Therefore, in order to avoid the above-mentioned situation where they can still be conductive, it is necessary to ensure that the inlet 121 of at least one of the adjacent mounting bases 12 can protrude from the surface of the cover 11.

[0048] In an optional embodiment, the access port 121 of the mounting base 12 is provided with a detection element 22, and only one detection element 22 is independently provided in the access port 121 of the same mounting base 12. Thus, by independently setting each detection element 22 on each mounting base 12, it is further ensured that the detection elements 22 will not be interconnected and thus affect the accuracy of the detection results.

[0049] like Figure 4 As shown, this application embodiment provides a heating element assembly 20 for heating input water. The heating element assembly 20 employs the false alarm prevention structure 10 and heating element body 21 described in any of the above embodiments. The water flow direction within the heating element assembly 20 is as follows: Figure 4 As indicated by the middle arrow.

[0050] Specifically, a water storage cavity 211 is formed inside the heating element body 21 for storing input water. A cover 11 is placed over the opening of the heating element body 21, and detection elements 22 are provided on at least two mounting bases 12. The two detection elements 22 can be used to detect the upper limit and lower limit of the water level in the heating element body 21, respectively, so as to determine whether it is necessary to continue supplying water to the water storage cavity 211 and whether heating operation is required based on the upper limit and lower limit of the water level.

[0051] More specifically, after the cover 11 is placed on the heat tank body 21, water is supplied to the water storage cavity 211 by opening a water inlet 23 on the cover 11. The water inlet 23 penetrates the heat tank body 21 and is connected to the water storage cavity 211 formed inside the heat tank body 21. The water inlet 23 extends into a water inlet pipe 231 in the direction away from the cover 11. At the same time, a baffle 26 is also provided on the surface of the cover 11 facing the water storage cavity 211. In this embodiment, the baffle 26 can be set as an annular baffle. The annular baffle is set around the water inlet 23. When water is input into the water storage cavity 211 through the water inlet 23, when the water flows out of the water inlet 23, the annular baffle can guide the flow direction of the water to prevent the water flowing out of the water inlet 23 from spreading to the surroundings.

[0052] More specifically, the inlet 23 is preferably located away from the mounting base 12 and the detection element 22 to prevent the water flowing from the inlet 23 into the water storage chamber 211 from splashing directly onto each mounting base 12 and the detection element 22, thereby causing the detection elements 22 on each mounting base 12 to communicate with each other and cause false alarms.

[0053] Furthermore, an annular baffle is disposed at the connection between the water inlet 23 and the water storage chamber 211, and the annular baffle can only cover the peripheral part of the water inlet 23. Therefore, when water is input into the water storage chamber 211 through the water inlet 23, the input water can only splash towards the peripheral part not blocked by the water inlet 23, and cannot splash out through the annular baffle. In this embodiment, the annular baffle is disposed on the side of the water inlet 23 corresponding to the installation position of the detection element 22. Therefore, when water flows in from the water inlet 23, the annular baffle can prevent water from directly splashing onto the detection element 22, thereby preventing water from flowing between the detection elements 22 and forming an electrical connection between them, which could lead to detection errors.

[0054] In an optional embodiment, in order to discharge the high-pressure gas in the water storage chamber 211, a through exhaust port 24 can be opened on the cover 11. The exhaust port 24 extends radially along the cover 11 to form an exhaust pipe 241, and the exhaust pipe 241 is located on the side of the cover 11 away from the mounting base 12, thereby enabling the smooth discharge of high-pressure gas in the heat tank body 21.

[0055] In addition, the heating element (not shown in the figure) is provided in the heating element 20 to heat the water in the input water storage chamber 211.

[0056] Specifically, such as Figure 4As shown, in this embodiment, the cover 11 is provided with four detection elements 22, which are respectively set on the corresponding mounting bases 12 to obtain different water levels in the water storage chamber 211. At least two detection elements 22 are provided here, and the two detection elements 22 can obtain at least the upper limit and the lower limit of the water level in the water storage chamber 211.

[0057] During operation, water is first supplied to the water storage chamber 211 through the inlet 23 until the water level in the storage chamber 211 reaches the upper limit. Then, the supply of water to the storage chamber 211 stops, and the heating element starts working until the water in the storage chamber 211 is heated to the set temperature and then heating stops. The bottom of the heating element body 21 is also provided with an outlet 25, which can be connected to a hot water pump (not shown in the figure). The hot water pump (not shown in the figure) can be output signal commands through the PCB so that the hot water pump (not shown in the figure) can switch between the on and off states.

[0058] Therefore, when the water in the heating element assembly 20 is heated, a large amount of water vapor will be generated. This water vapor will condense into water droplets on the cover 11, the mounting base 12, and the detection element 22. If the inlet 121 of the mounting base 12 is on the same horizontal plane as the surface of the cover 11, the condensed water droplets may conduct electricity to adjacent detection elements 22. Therefore, to avoid this situation, the inlets 121 of adjacent mounting bases 12 and detection elements 22 can be set to be on different horizontal planes. Furthermore, the mounting base 12 can be set to a stepped structure to limit the possibility of adjacent detection elements 22 conducting electricity under the action of water droplets, thereby effectively preventing the detection element 22 from triggering an abnormal alarm.

[0059] This application provides a water purification device that uses the heating element 20 described in any of the above embodiments, and therefore also has the above advantages.

[0060] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0061] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0062] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
