Description
Technical Field
[0001] This invention relates to the field of household appliance accessories technology, specifically to a tilt-type steam cover with a double-spring leak-proof structure, suitable for containers that require steam discharge, such as electric kettles, health pots, electric steamers, and water-boiling humidifiers. Background Technology
[0002] Most existing containers with steam venting functions (such as electric kettles and health pots) rely solely on a single gravity ball for leak-proof sealing, which has the following drawbacks: slow sealing response when tipped over, prone to leakage, and unreliable sealing at small tilt angles due to the reliance on a rolling gravity ball. Furthermore, the lack of auxiliary sealing structures means that the gravity ball can easily dislodge from its sealing position when subjected to vibration or container shaking, leading to leak-proof failure and increasing the safety risks of burns or electrical short circuits. Summary of the Invention
[0003] To address the technical problem in existing technologies where lidded containers tip over, resulting in slow sealing response and leakage failure when tilted at small angles or subjected to vibration or shaking, this invention provides a tipping-proof steam-proof lid with a double-spring leak-proof structure.
[0004] The technical solution adopted is as follows: A tilting steam cover with a double-spring leak-proof structure includes an upper cover, a lower cover, and a steam channel. The steam channel is installed in a cavity formed by the upper and lower covers when they are fastened together. The upper cover has an upper cover steam outlet. The two ends of the steam channel have a channel steam outlet and a channel steam inlet, which are respectively connected to the internal flow channel. The upper end of the steam channel surrounds the upper cover steam outlet in a sealed connection, and the channel steam outlet is connected to the upper cover steam outlet. The lower end of the steam channel has a receiving groove I, and the channel steam inlet is located at the top of the receiving groove I. The lower cover has a lower cover steam inlet connected to the receiving groove I. When the lower end of the steam passage is installed on the lower cover, the receiving groove I and the lower cover are connected to form a gravity ball receiving cavity. The gravity ball receiving cavity is provided with a gravity ball and a first spring. The first spring is installed on the lower cover. The gravity ball abuts against the upper end of the first spring. The diameter of the gravity ball is slightly smaller than the internal size of the gravity ball receiving cavity. The steam inlet of the passage is located directly above the gravity ball. A water sealing valve assembly is also provided above the gravity ball. The water sealing valve assembly is located inside the steam channel and includes a water sealing valve and a second spring. The lower end of the second spring is connected to the upper end of the water sealing valve, and the upper end of the second spring is fixed inside the steam channel. The water sealing valve passes through the steam inlet hole of the channel, and its lower valve plate is located in the gravity ball receiving cavity and abuts against the gravity ball. When the gravity ball receiving cavity is tilted, the valve plate moves up and seals the steam inlet hole of the channel.
[0005] Preferably, the sealing valve includes a valve plate, a valve stem, and a valve seat. The valve seat is a groove disposed in the internal flow channel. The upper end of the second spring is installed inside the valve seat. The valve stem passes through the steam inlet hole of the channel and is fixedly connected to the valve plate. The upper end of the valve stem is fixedly connected to the second spring.
[0006] Furthermore, a recessed receiving groove II is formed on the lower cover, and the steam inlet of the lower cover is located on the side wall of the receiving groove II. After the receiving groove I and the receiving groove II are connected, the gravity ball receiving cavity is formed. The first spring is installed at the bottom of the receiving groove II, and the gravity ball is placed in the receiving groove II and abuts against the upper end of the first spring.
[0007] Preferably, the bottom of the receiving groove II is further provided with a spring mounting groove, and the first spring is installed in the spring mounting groove.
[0008] More preferably, the lower end of the steam channel forms two parallel receiving grooves I, and the lower cover forms two receiving grooves II corresponding to the receiving grooves I, with the first spring and gravity ball respectively provided in the two receiving grooves II.
[0009] More preferably, the internal flow channel in the steam channel is a noise-reducing flow channel comprising multiple continuously bent bends.
[0010] Furthermore, a sealing groove is provided near the lower edge of the lower cover, and a steam inlet cover is fixedly connected to the lower cover. A sealing ring is installed on the edge of the steam inlet cover and is installed in the sealing groove. The steam inlet cover is also provided with a first steam inlet that communicates with the steam inlet of the lower cover.
[0011] Preferably, the steam inlet cover is further provided with a recessed cavity, which is fitted outside the receiving groove II and is sealed to the bottom of the lower cover by waterproof silicone. The first steam inlet is located inside the recessed cavity.
[0012] Preferably, the upper cover has a downwardly extending steam outlet in the middle, which is fitted inside the upper end of the steam channel, and the upper end of the steam channel is sealed to the bottom of the upper cover.
[0013] Preferably, the steam outlet of the upper cover has a plurality of spaced-apart strip-shaped steam outlet holes.
[0014] The technical solution of the present invention has the following advantages: A. This invention provides a steam channel between the upper and lower covers, and a gravity ball and a first spring for preventing water leakage during tilting are installed in the gravity ball receiving cavity formed between the lower end of the steam channel and the lower cover. A water sealing valve assembly linked with the first spring is also installed directly above the gravity ball. When the cover swings due to vibration, the valve plate of the water sealing valve is pushed by the first spring and the gravity ball to seal the steam inlet of the channel to prevent leakage. When the cover is in normal use, the water sealing valve is pushed open with the help of the elastic force of the second spring to prevent the valve plate of the water sealing valve from blocking the steam inlet of the channel, thus greatly improving product safety.
[0015] B. This invention combines a gravity ball and a second spring, enabling the linkage structure between the gravity ball and the water sealing valve to be quickly activated when the container with the lid is tipped over. This instantly seals the steam inlet of the channel, resulting in a faster response and avoiding water leakage problems in the initial stage of tipping over. At the same time, as the lid moves from a tilted state to an upright state, the second spring can quickly push the valve plate to open the steam inlet of the channel, restoring the channel air inlet on the lid to its normal steam discharge state. This avoids the technical problem of not being able to quickly open the channel air inlet due to adhesion or other reasons.
[0016] C. The present invention has a compact overall structure and achieves leak prevention only through the cooperation of the first spring, the second spring, the gravity ball, and the sealing valve. It does not require additional power or complex mechanisms, has low manufacturing cost and low failure rate, effectively avoids water leakage when the container is overturned, prevents scalding or electrical short circuits, and significantly improves the safety of product use.
[0017] D. This invention features multiple continuous, bent noise-reducing channels within the steam channel's internal flow path. During normal use, the steam will flow back along these noise-reducing channels, increasing the steam flow distance and allowing water droplets carried in the steam to flow back into the water tank. This avoids the technical problem of large water droplets being carried to the outside of the lid by the discharged steam, resulting in a wet desktop or floor. It also eliminates the noise generated when the steam is discharged. Attached Figure Description

Detailed Implementation
[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] like Figures 1 to 4 As shown, this invention provides a tilt-proof steam cover with a double-spring leak-proof structure, including an upper cover 1, a lower cover 2, and a steam channel 3. The steam channel 3 is installed in the cavity h formed after the upper cover 1 and the lower cover 2 are fastened together. Figure 1The upper cover 1 has a steam outlet a in the middle. The two ends of the steam channel 3 have a channel steam outlet b and a channel steam inlet c, respectively, connected to the internal flow channel i. The upper end of the steam channel 3 is sealed around the upper cover steam outlet a, and the channel steam outlet b is connected to the upper cover steam outlet a. The lower end of the steam channel 3 has a receiving groove I31, and the channel steam inlet c is located at the top of the receiving groove I31. The lower cover 2 has a lower cover steam inlet d connected to the receiving groove I31. Multiple d inlets can be provided. The edge of the receiving groove I31 is... The lower cover 2 forms a sealed connection through the annular sealing gasket 9; when the lower end of the steam passage 3 is installed on the lower cover 2, the receiving groove I31 and the lower cover 2 are connected to form a gravity ball receiving cavity e. The gravity ball receiving cavity e is provided with a gravity ball 6 and a first spring 7. The first spring 7 is installed on the lower cover 2, and the upper end of the gravity ball 6 abuts against the first spring 7. The diameter of the gravity ball 6 is slightly smaller than the internal size of the gravity ball receiving cavity e, so that the gravity ball 6 can roll in the gravity ball receiving cavity e. The steam inlet c of the passage is located directly above the gravity ball 6. The present invention further provides a water sealing valve assembly 10 directly above the gravity ball 6. The water sealing valve assembly 10 is located inside the steam channel 3 and includes a water sealing valve 101 and a second spring 102. The lower end of the second spring 102 is connected to the upper end of the water sealing valve 101, and the upper end of the second spring 102 is fixed inside the steam channel 3. The present invention provides a valve seat 1013 inside the steam channel 3. Here, the valve seat 1013 is preferably a groove structure. The upper end of the second spring 102 is fixed in the groove of the valve seat 1013, and the lower end of the second spring 102 is connected to the water sealing valve 101. The water sealing valve 101 includes a valve plate 1011 and a valve stem 1012. The valve stem 1012 passes through the steam inlet hole c of the channel. The valve plate 1011 is vertically fixed to the lower end of the valve stem 1012 and is located in the gravity ball receiving cavity e and abuts against the gravity ball 6. The upper end of the valve stem 1012 is fixedly connected to the second spring 102.
[0023] Under normal use, the sealing valve 101 is in a downward state under the elastic force of the second spring 102 and its own weight, the steam inlet hole c of the channel is open, and steam can be discharged normally. Under normal use, the sealing valve 101 can ensure that the steam inlet hole c of the channel is open under the elastic force of the second spring 102, so as to ensure the discharge of internal airflow.
[0024] When the container with the lid of this invention is tipped over, the gravity ball receiving cavity e in the lid is tilted, the force acting on the first spring 7 decreases, the first spring 7 extends and drives the gravity ball 6 to move upward, the gravity ball 6 further pushes the valve plate 1011 and valve stem 1012 to move upward, the second spring 102 is compressed and contracts, the valve plate 1011 and the steam inlet hole c of the channel form a tight seal, avoiding the problem of water leakage when the lid is tipped over, and has the characteristics of rapid response.
[0025] As a further preferred embodiment of the present invention, a sunken receiving groove II21 is formed inside the lower cover 2. The steam inlet d of the lower cover is set on the side wall of the receiving groove II21. When the lower end of the steam passage 3 is installed on the lower cover 2, the receiving groove I31 and the receiving groove II21 are connected to form a gravity ball receiving cavity e. The dimensions of the receiving groove I31 and the receiving groove II21 are consistent. The first spring 7 is installed at the bottom of the receiving groove II21. The gravity ball 6 is placed in the receiving groove II21 and abuts against the upper end of the first spring 7. The diameter of the gravity ball 6 is slightly smaller than the internal size of the gravity ball receiving cavity e. Here, the gravity ball receiving cavity e plays a good limiting role for the gravity ball 6. When the entire cover is kept upright, the sealing valve 101 and the gravity ball 6 compress the first spring 7 under their own weight, thereby keeping the steam inlet c at the lower end of the steam channel 3 open. The steam entering from the steam inlet d of the lower cover enters the gravity ball cavity and enters from the steam inlet c of the channel, passes through the internal flow channel i, and then exits through the steam outlet b of the channel and the steam outlet a of the upper cover in sequence.
[0026] like Figure 1 As shown in the figure, the internal flow channel i in the steam channel 3 of this invention comprises multiple continuously bent noise-reducing channels. The figure shows a transversely bent noise-reducing channel, but a vertically bent noise-reducing channel can also be used, which will not be elaborated here. The steam inlet c is located at the beginning of the internal flow channel i, and the steam outlet b is located at the end of the internal flow channel i, and the steam outlet b is correspondingly connected to the steam outlet a of the upper cover. The multi-segment continuously bent noise-reducing channel structure greatly extends the flow distance of the steam. At the same time, each bent channel is inclined, and larger water droplets in the steam will flow back along the inclined bent channels into the gravity ball receiving cavity e, and then flow out from the steam inlet d of the lower cover. This avoids the technical problem of the discharged steam carrying large water droplets to the outside of the cover, and also eliminates the noise generated when the steam is discharged.
[0027] from Figure 3 As can be seen, the upper cover 1 has a downward-extending steam outlet a in the middle. The steam outlet a is fitted inside the upper end of the steam channel 3. The upper end of the steam channel 3 and the bottom of the upper cover 1 are sealed together by an annular sealing gasket 9, thereby preventing steam from entering the cavity h. In this invention, multiple spaced strip-shaped steam outlets are formed at the upper cover steam outlet a, which not only discharges steam but also has a good decorative effect.
[0028] from Figure 1-3 As can be seen, the edge of the upper cover 1 and the edge of the lower cover 2 are fastened together and fixed together by a fastening connector. At this time, the steam channel 3 is located in the cavity h. The upper and lower ends of the steam channel 3 correspond to the steam outlet a of the upper cover and the gravity ball cavity e, respectively, and are sealed with a sealing gasket 9 to prevent steam from entering the cavity h.
[0029] In addition, the present invention also provides a spring mounting groove 22 at the bottom of the receiving groove II21 for placing the first spring 7. The first spring 7 is installed in the spring mounting groove 22, and the upper end of the first spring 7 abuts against the gravity ball 6. The gravity ball 6 is in a free state in the receiving groove II21.
[0030] Of course, the present invention can provide multiple gravity sphere receiving cavities e, such as... Figure 3 As shown, this invention features two parallel gravity ball receiving cavities e. Specifically, two parallel receiving grooves I31 are provided at the lower end of the steam channel 3, and two receiving grooves II21 corresponding to the receiving grooves I31 are formed on the lower cover 2. Each receiving groove II21 contains a corresponding first spring 7 and a gravity ball 6, and a water sealing valve assembly 10 is provided above the two gravity ball receiving cavities e. Each receiving groove II21 has multiple lower cover steam inlets d on its side wall, allowing for greater steam discharge during normal use.
[0031] like Figure 4 As shown, to improve the sealing performance of the cover, a sealing groove 23 is provided near the lower edge of the lower cover 2. A steam inlet cover 5 is also provided below the lower cover 2 and fixedly connected thereto. A sealing ring 4 is installed on the edge of the steam inlet cover 5, and the sealing ring 4 is installed in the sealing groove 23. The steam inlet cover 5 also has a first steam inlet f that communicates with the steam inlet d of the lower cover. The steam inlet cover 5 is connected to the bottom of the lower cover 2 by a fastener, which is used to fix the water tank sealing ring 4 and strengthen the overall structure of the cover.
[0032] The present invention further provides a recessed cavity g in the central region of the steam inlet cover 5, such as... Figure 3 As shown, the concave cavity g is placed outside the receiving groove II21 and forms a sealed connection with the bottom of the lower cover 2 through the waterproof silicone 8. The first steam inlet f is set inside the concave cavity g. When the steam inlet cover 5 is fixed to the bottom of the lower cover 2 through the fastening connector, the concave cavity g of the steam inlet cover 5 and the bottom of the lower cover 2 form a sealed connection through the annular waterproof silicone 8.
[0033] Install the annular sealing gasket 9 on the upper end of the steam channel 3, then install the steam channel 3 on the upper cover 1. The steam channel 3 is fixed to the upper cover 1 with screws. Place the first spring 7 on the mounting position of the receiving groove II of the lower cover 2. Place the second spring 102 in the valve seat 1013 inside the steam channel 3, and install the water sealing valve 101 on the steam channel 3. Place another annular sealing gasket 9 at the lower end of the steam channel 3. Then place the gravity ball 6 on the receiving groove II 21 of the lower cover 2. Then install and fix the lower cover 2 on the upper cover 1. Then install the sealing ring 4 on the edge of the steam inlet cover 5. The steam inlet cover 5 is preferably made of stainless steel. A waterproof silicone 8 is also provided between the steam inlet cover 5 and the lower cover 2. When the product is working, the steam generated enters from the first steam inlet f of the steam inlet cover 5, flows through the lower cover steam inlet d through the gravity ball receiving cavity e where the gravity ball 6 is set, flows into the steam channel 3 from the channel steam inlet c, and then exits from the upper cover steam outlet a. Under normal use conditions:
[0034] like Figure 1 As shown, the lid provided by this invention is sealed and fastened at the container opening. When the container is in an upright and normal use state, the gravity ball 6 compresses the first spring 7 under its own weight and remains within the lower cover receiving groove II21. At this time, the steam inlet c is open, and the steam generated inside the container enters the gravity ball receiving cavity e through the first steam inlet f, passes through the steam inlet c, the internal flow channel i, and the steam outlet b, and finally exits from the upper cover steam outlet a. In the tip-over leak-proof state:
[0035] like Figure 2 As shown, when the container accidentally tipes over, the gravity ball 6 rolls towards the receiving tank I under the action of gravity. At the same time, the first spring 7 releases the compressed elastic force and applies a thrust towards the steam inlet c of the channel to the gravity ball 6, so that the valve plate 1011 fits tightly against the steam inlet c of the channel, completely blocking the steam inlet c of the steam channel. At this time, the second spring 102 is in a compressed state, and the water in the container cannot flow out through the steam inlet c of the channel, thereby achieving the effect of preventing water leakage. The reset process is as follows:
[0036] When the container returns to an upright position, under the rebound force of the second spring 102 and the self-weight of the sealing valve 101 and the gravity ball 6, the gravity ball 6 rolls back into the receiving groove II21 of the lower cover 2 and compresses the first spring 7. The steam inlet hole c of the channel reopens, and the steam resumes normal discharge.
[0037] This invention effectively avoids water leakage when the container is tipped over, prevents scalding or electrical short circuits, and improves the safety of product use.
[0038] Any aspects not covered in this invention are applicable to existing technologies.
[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
