Description

Technical Field

[0001] This utility model belongs to the field of water vapor equipment technology, and in particular relates to a water tank component and a water vapor generating device. Background Technology

[0002] In some water vapor generating devices, a water tank is usually installed for water supply, and a switch is installed at the outlet of the water tank to control its opening and closing. In the prior art, there is a problem that the switch has poor sealing effect when it is closed.

[0003] Taking a garment steamer as an example, if the water level in the evaporation chamber is too high, it can easily cause water spraying problems; if the water level is too low, it may cause dry burning, thus shortening the lifespan of the equipment. To achieve precise water level control in a garment steamer, when the water level exceeds the set value, a sealing measure is used to prevent water from the tank from continuing to flow into the evaporation chamber, thereby preventing the water level from rising continuously; when the water level is below the set value, the tank will open, allowing water to flow into the evaporation chamber. Therefore, ensuring a reliable seal at the water tank's sealing points is crucial. In existing technologies, the sealing structure is prone to loosening or inadequate sealing at the sealing points, resulting in the water tank failing to effectively block water flow when a seal is needed, thus affecting the normal operation of the equipment.

[0027] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0028] In some water vapor generating devices, a water tank is usually installed for water supply, and a switch is installed at the outlet of the water tank to control its opening and closing. In the prior art, there is a problem that the switch has poor sealing effect when it is closed.

[0029] Taking a garment steamer as an example, if the water level in the evaporation chamber is too high, it can easily cause water spraying problems; if the water level is too low, it may cause dry burning, thus shortening the lifespan of the equipment. To achieve precise water level control in a garment steamer, when the water level exceeds the set value, a sealing measure is used to prevent water from the tank from continuing to flow into the evaporation chamber, thereby preventing the water level from rising continuously; when the water level is below the set value, the tank will open, allowing water to flow into the evaporation chamber. Therefore, ensuring a reliable seal at the water tank's sealing points is crucial. In existing technologies, the sealing structure is prone to loosening or inadequate sealing at the sealing points, resulting in the water tank failing to effectively block water flow when a seal is needed, thus affecting the normal operation of the equipment.

[0030] In existing technologies, the sealing structure used is too flimsy, and once the sealing plug becomes misaligned, it is easy to cause problems with poor sealing.

[0031] In view of this, this utility model embodiment provides a water tank assembly 100, which aims to improve the reliability of the water tank seal. The water tank assembly 100 is applicable to water vapor generating devices, such as humidifiers, garment steamers, steam engines, ultrasonic cleaners, etc.

[0032] Please see Figure 1 and Figure 2 The water tank assembly 100 includes a tank body 1 and a floating assembly 3. The tank body 1 stores liquid and has a water outlet port 11 at the bottom for liquid outflow. The floating assembly 3 includes a floating element 31 located below the water outlet port 11. The floating element 31 switches between sealed and open states by floating up and down, thereby controlling the flow of liquid. The floating assembly 3 may also include a float 33 connected to the floating element 31 to increase buoyancy. In specific implementations, the up and down movement of the floating element 31 can be achieved in various ways, such as utilizing buoyancy generated by water level changes, or using an external driving device or gravity. It should be noted that the up and down movement of the floating element 31 can be vertical or inclined. The vertical direction is represented by dashed line a in the figure, and the horizontal direction is represented by dashed line b.

[0033] Please continue reading. Figure 1 and Figure 2The water tank assembly 100 also includes at least two annular abutment portions 2; each annular abutment portion 2 extends downward and is arranged in an inner and outer ring configuration; this "inner and outer ring configuration" can be understood as the abutment portions nesting within each other. Furthermore, each annular abutment portion 2 is located at the lower end of the tank body 1, at the water outlet port 11. Therefore, each annular abutment portion 2 surrounds the periphery of the water outlet port 11, forming a multi-layer sealing structure. One of the annular abutment portions 2 includes a sealing ring 2A located at the water outlet port 11 and extending downward. This sealing ring 2A is made of an elastic material, capable of deformation under force, thereby enhancing the sealing effect. The remaining annular abutment portions 2 can be one or more. Each of the remaining annular abutment portions 2 can be made of either an elastic material or a rigid material. Using an elastic material further improves the tightness of the seal; using a rigid material provides a more stable support structure, ensuring that the sealing ring 2A does not deform excessively under pressure, thereby maintaining reliable sealing performance. Each of the remaining annular abutment portions 2 can be either an independent component from the housing 1 or an integrally formed component with the housing 1. In other words, the number and material of the other annular abutment portions 2 can be adjusted according to specific needs to meet different sealing requirements.

[0034] Furthermore, the upper end of the floating component 31 is provided with a mating part 32, which can be integrally formed with the floating component 31 or be a relatively independent component. This mating part 32 is adapted to each of the annular abutment parts 2 to achieve a multi-layer sealing connection. The specific principle of water level control is as follows: when the water level drops below the set value, the floating component 31 sinks to the open position, at least a portion of the mating part 32 separates from each of the annular abutment parts 2, and the water outlet port 11 opens. Figure 2 As shown, liquid is replenished; when the water level rises above the set value, the floating member 31 floats upward to the sealing position, and the mating part 32 again forms a multi-layer sealing contact with each annular contact part 2, as shown. Figure 3 As shown, the water outlet port 11 is closed to avoid problems caused by excessive water supply. Here, "sealed contact" can be understood as a tight contact contact method, and through this tight contact contact method, the water outlet port 11 is sealed.

[0035] Among them, multi-layer sealing structures provide a more reliable sealing effect compared to single-layer seals, reducing the risk of leakage due to poor sealing. This is because even if a sealing layer has minor defects or deformation, the other sealing layers can still function, thereby improving the overall stability of the sealing performance.

[0036] In summary, the water tank assembly 100 provided in this embodiment includes a tank body 1 and a floating assembly 3. The tank body 1 has a water outlet port 11 at its bottom. At least two downwardly extending annular abutment portions 2, arranged in an inner and outer ring configuration, are provided at the lower end of the tank body 1 and at the water outlet port 11. One of the at least two annular abutment portions 2 includes a sealing ring 2A located at the water outlet port 11 and extending downwards. The floating assembly 3 includes a floating member 31 that is buoyantly disposed below the water outlet port 11. A mating portion 32 is provided at the upper end of the floating member 31. The mating portion 32 seals against the two annular abutment portions 2 to seal the water outlet port 11. The mating portion 32 is at least partially separated from the two annular abutment portions 2 to open the water outlet port 11. This embodiment of the invention achieves the switching between a sealed state and an open state by providing at least two annular abutment portions 2 at the water outlet port 11 and coordinating with the up-and-down floating action of the floating member 31. As the floating component 31 rises to the sealing position, multiple annular abutment portions 2 and mating portions 32 seal against each other, forming a multi-layered sealing barrier. This multi-layered sealing barrier improves the reliability of the seal, ensuring that even if one layer of the seal experiences slight deformation or defects, the remaining sealing layers can still maintain overall sealing performance, thereby significantly reducing the risk of leakage.

[0037] In some embodiments, please refer to Figure 2 To ensure a more secure installation of the sealing ring 2A and enhance the overall sealing effect of the water tank assembly 100, a protrusion 12 is provided at the lower end of the tank body 1. Specifically, the sealing ring 2A is fitted around the protrusion 12, and the water outlet 11 is located on the protrusion 12. That is to say, the interior of the protrusion 12 is hollow. Thus, the liquid in the water tank flows out through the interior of the protrusion 12 after passing through the water outlet 11.

[0038] In the actual design process, the structure of the outer surface of the protrusion 12 can be optimized to make its connection with the sealing ring 2A tighter. For example, an annular groove or thread can be machined on the outer surface of the protrusion 12. These structures can increase the contact area between the sealing ring 2A and the protrusion 12, and the annular groove can allow the sealing ring 2A to be partially embedded therein, while the thread can generate friction through its texture, reducing the risk of it sliding or falling off.

[0039] In this embodiment of the invention, a protrusion 12 is provided at the lower end of the housing 1. The sealing ring 2A is fitted around the protrusion 12, and the water outlet 11 is located on the protrusion 12. The protrusion 12 provides a clear and stable mounting carrier for the sealing ring 2A. This reduces the risk of the sealing ring 2A shifting due to external factors such as vibration and collision during equipment use, ensuring that the sealing ring 2A is always in the correct sealing position, thereby maintaining the stability of the sealing performance. At the same time, the structure of the protrusion 12 also makes the relative position of the sealing ring 2A and the water outlet 11 more accurate, further improving the sealing fit.

[0040] In some embodiments, please refer to Figure 2 To further enhance the installation stability of the sealing ring 2A, an annular bracket 2B is fitted around the periphery of the protrusion 12. Specifically, the sealing ring 2A is sandwiched between the annular bracket 2B and the protrusion 12; the annular bracket 2B forms another annular abutment portion 2.

[0041] The annular bracket 2B can be a separate component, fixed to the periphery of the protrusion 12 by fasteners or snap-fit ​​structures, or it can be integrally formed with the protrusion 12 or the housing 1 to reduce assembly steps and improve the overall structural strength. The annular bracket 2B can be made of a rigid material, such as metal or hard plastic, to provide sufficient support and prevent the sealing ring 2A from deforming excessively under pressure.

[0042] In practical implementation, the sealing ring 2A and mating part 32 can be made of soft materials such as silicone, while the annular bracket 2B can be made of slightly harder materials such as plastic. When the mating part 32 abuts against the sealing ring 2A and the annular bracket 2B, the inner layer is a soft sealing barrier, and the outer layer is a harder sealing barrier, thus forming multiple sealing forms that combine soft and hard materials. It can be understood that this combination of soft and hard materials, compared to a single sealing form, can achieve a superimposed effect of "double protection and adaptive adjustment". The harder outer plastic annular bracket 2B can provide stable structural support, preventing the soft inner material from deforming excessively due to excessive pressure and losing its sealing function. At the same time, it maintains the overall flatness of the sealing surface by its own rigidity, forming the first line of structurally stable sealing defense. The soft silicone sealing ring 2A and mating part 32 can fill the tiny gaps in the contact surface through their own deformation. For example, the tiny burrs generated by injection molding of the annular bracket 2B and the slight unevenness on the surface of the protrusion 12 can be covered by the elastic deformation of the silicone, forming a second tightly fitting sealing barrier.

[0043] Furthermore, the protrusion 12, the sealing ring 2A, and the annular bracket 2B form an interlocking structure, i.e., coaxial arrangement. During assembly, it is a straight-up-down assembly, which is very convenient.

[0044] In this embodiment of the invention, the annular bracket 2B provides lateral support for the sealing ring 2A, stably clamping it between the annular bracket 2B and the protrusion 12. This prevents the sealing ring 2A from deforming or shifting due to internal factors such as water pressure, thus enhancing the stability of the sealing ring 2A installation. Furthermore, the annular bracket 2B, as another annular abutment part 2, forms a double abutment structure with the original sealing ring 2A, creating a double seal when the mating part 32 abuts, further reducing the probability of seal failure.

[0045] In some embodiments, please refer to Figure 2In order to enhance the sealing effect between the sealing ring 2A and the protrusion 12, and / or, in order to enhance the sealing effect between the sealing ring 2A and the annular body 21A, the structure of the sealing ring 2A has been optimized.

[0046] Specifically, the sealing ring 2A includes an annular main body portion 21A fitted between the annular bracket 2B and the protrusion 12. The inner surface of the annular main body portion 21A is provided with a first annular protrusion 211A, which seals against the protrusion 12; and / or, the outer surface of the annular main body portion 21A is provided with a second annular protrusion 212A, which seals against the annular bracket 2B. The shape, size, and number of the first annular protrusion 211A and the second annular protrusion 212A can be adjusted according to specific circumstances. For example, trapezoidal, semi-circular, or other cross-sectional shapes of the protrusions can be used.

[0047] In actual assembly and use, the sealing function of the first annular protrusion 211A and the second annular protrusion 212A both rely on their deformable characteristics. Specifically, the first annular protrusion 211A is made of soft materials such as silicone. When it is fitted around the protrusion 12 and compressed by the protrusion 12 and the annular support 2B, it will adaptively deform along the surface contour of the protrusion 12. Even if there are minor unevenness or scratches on the surface of the protrusion 12, this deformation can allow the protrusion to fit tightly against the surface, eliminating gaps like a "filler," thereby forming a stable and reliable sealing effect and preventing liquid from seeping out from the gap between the protrusion 12 and the sealing ring 2A. The sealing principle of the second annular protrusion 212A is similar. After the sealing ring 2A is assembled in place, the second annular protrusion 212A will contact and be compressed against the inner wall of the annular support 2B. By utilizing its own elastic deformation, it can tightly "bite" the contact surface of the annular bracket 2B, increasing the friction and sealing force between the two, and improving the sealing performance between the sealing ring 2A and the annular bracket 2B.

[0048] This embodiment of the invention further optimizes the sealing structure by providing a first annular protrusion 211A and / or a second annular protrusion 212A on the sealing ring 2A. The tight fit between the first annular protrusion 211A and the protrusion 12 enhances the sealing performance of the inner side of the sealing ring 2A; while the second annular protrusion 212A enhances the sealing performance of the outer side of the sealing ring 2A through its tight contact with the annular bracket 2B.

[0049] In some embodiments, please refer to Figure 2To further enhance the sealing performance of the seal, its structure has been further optimized. Specifically, the sealing ring 2A also includes an annular outward-curving portion 22A located on the annular main body 21A; the annular outward-curving portion 22A is sandwiched between the upper end of the annular bracket 2B and the bottom of the housing 1. As can be seen from the name "annular outward-curving portion 22A," this annular outward-curving portion 22A and the annular main body 21A are integrally molded. Of course, for silicone material, the outward curving is actually a structural extension achieved through mold design during the molding process. Since the annular outward-curving portion 22A and the annular main body 21A are integrally molded, they maintain consistency in material and possess good elasticity and deformation capacity. Moreover, the integrally molded structure eliminates the connection gap between the annular outward-curving portion 22A and the annular main body 21A, avoiding the risk of leakage due to loose connection.

[0050] When the annular flared portion 22A is sandwiched between the upper end of the annular bracket 2B and the bottom of the housing 1, it undergoes lateral deformation under the pressure of both. This deformation allows the annular flared portion 22A to fit tightly against the upper surface of the annular bracket 2B and the bottom of the housing 1. Even if there are minor imperfections on these two contact surfaces, such as tiny dents or protrusions, the annular flared portion 22A can cover them through its own deformation, thus forming a new sealing barrier at this contact point. Simultaneously, the annular flared portion 22A effectively increases the sealing length of the seal. This means that water needs to travel a longer path to leak from the seal. During this process, the friction and sealing force between the seal and each contacting component create a stronger barrier against water leakage, reducing the possibility of leakage.

[0051] This embodiment of the invention further improves the sealing performance by adding an annular outward-flaring portion 22A to the sealing ring 2A.

[0052] In some embodiments, please refer to Figure 2 In order to improve the sealing effect of the annular folded portion 22A, a third annular protrusion 221A is provided on the upper side of the annular folded portion 22A to abut against the bottom of the housing 1; and / or, a fourth annular protrusion 222A is provided on the lower side of the annular folded portion 22A to abut against the upper end of the annular bracket 2B.

[0053] In actual assembly and use, the sealing function of the third annular protrusion 221A and the fourth annular protrusion 222A is similar to that of the first annular protrusion 211A and the second annular protrusion 212A, and will not be described in detail here.

[0054] In some embodiments, please refer to Figure 2At least one annular mating rib 321 is provided on the upper side of the mating part 32 corresponding to the position of the annular bracket 2B. The annular mating rib 321 is used to seal against the lower end of the annular bracket 2B. And / or, the upper side of the mating part 32 is provided to protrude upwards corresponding to the position of the sealing ring 2A to form a boss 322. The boss 322 is used to seal against the lower end of the sealing ring 2A.

[0055] The annular mating rib 321 operates on a similar principle to the first annular protrusion 211A and the second annular protrusion 212A. The annular mating rib 321, through its own elastic deformation, tightly adheres to the lower end face of the annular bracket 2B, thereby improving the sealing performance between the mating part 32 and the annular bracket 2B.

[0056] The presence of the boss 322 increases the compression between the boss 322 and the sealing ring. Specifically, when the mating part 32 abuts against the sealing ring and the annular bracket 2B, the annular bracket 2B abuts against the lower part of the outer periphery of the boss 322, while the sealing ring abuts against the higher boss 322, resulting in a "high-low misalignment" compression fit. The higher boss 322 exerts stronger pressure on the sealing ring 2A, causing the sealing ring 2A to undergo targeted deformation. This is equivalent to "forcing" the sealing ring 2A to improve its radial sealing performance through the protrusion height of the boss 322.

[0057] This embodiment of the utility model improves sealing performance and provides "redundant protection" for the equipment by setting the annular mating rib 321 and / or boss 322.

[0058] In some embodiments, please refer to Figure 2 The inner cavity of the annular bracket 2B gradually narrows from top to bottom. Thus, as the annular bracket 2B is fitted over the sealing ring 2A, the connection between the annular bracket 2B and the sealing ring 2A becomes increasingly tighter, thereby improving the reliability of the seal between them.

[0059] In some embodiments, please refer to Figure 1 To better meet water level control requirements, a water outlet cavity 4 is specifically designed on the outer side of the lower end of the tank 1. Specifically, the water outlet port 11 is located at the connection point between the tank 1 and the water outlet cavity 4, while the floating assembly 3 is installed inside this water outlet cavity 4. This water outlet cavity 4 can be integrally formed with the tank 1; it can also be fixedly connected to the tank 1 via fasteners or snap-fit ​​structures; or it can be partially integrally formed with the tank 1, while the other part is fixedly connected via fasteners or snap-fit ​​structures, such as... Figure 2 and Figure 3 As shown.

[0060] The water outlet cavity 4 provided in this embodiment of the invention creates an independent and enclosed "working space" for the floating component 3. This space can isolate external interference, allowing the floating component 31 to float up and down flexibly. When the water level changes, the floating component 31 can adjust its state without obstruction, realizing the on / off control of the water outlet port 11, and providing a stable and reliable structural foundation for water level control.

[0061] This utility model embodiment also provides a water vapor generating device. Please refer to [link / reference]. Figure 4 The water vapor generating device includes a water vapor generating component 200 and a water tank component 100 provided in any of the above embodiments. The water outlet port 11 of the water tank component 100 is connected to the inner cavity of the water vapor generating component 200 to supply water to the water vapor generating component 200 through the water tank component 100.

[0062] The water vapor generating component 200 requires a stable water supply to generate water vapor, while the water tank component 100, through reliable sealing, can ensure the continuity and stability of the water supply, and there will be no interruption of water supply or insufficient water due to leakage, thus allowing the water vapor generating component 200 to generate water vapor stably.

[0063] In some embodiments, please refer to Figure 4 The steam generating device includes a garment steamer. During use, the internal pressure of the garment steamer is inevitably high due to the heating process that generates steam. Therefore, the stability of the steam and the sealing of the garment steamer's interior are crucial. A garment steamer equipped with the aforementioned water tank assembly 100, thanks to the excellent sealing of the water tank assembly 100, can prevent water or steam from flowing back into the housing 1 due to poor sealing, thus ensuring a stable steam output.
