Description

Technical Field

[0001] This utility model relates to the field of small household appliances, and in particular to a leak-proof bottle warmer. Background Technology

[0002] Currently, most bottle warmers on the market share a high degree of similarity in structural design. Their core working principle involves injecting water into the bottle warmer, using a heating element to heat the water, and then using heat transfer through the water to heat and keep the milk in the bottle placed inside the warmer warm. This technology effectively meets users' basic needs for heating and maintaining a constant temperature of milk, and is widely used in the field of infant feeding. However, in actual use, the waterproof and leak-proof performance of bottle warmers becomes a key factor restricting their safety and reliability. Because bottle warmers operate with water for extended periods, and are subject to shaking and tilting during water addition, replacement, and daily use, leaks can easily seep into the internal circuitry and heating elements, causing short circuits, component damage, and significantly reducing the product's lifespan. Furthermore, the risk of electric shock increases dramatically, potentially leading to electrocution and seriously threatening user safety.

[0003] Therefore, how to effectively improve the waterproof and leak-proof performance of bottle warmers has become a technical problem that urgently needs to be solved in this field. Utility Model Content

The inner wall of the base shell is provided with a pressing arm, which extends circumferentially along the base shell; the pressing arm is used to extend into the connecting groove and press the connecting ring after the connecting ring is installed in the connecting groove.

[0010] Furthermore, both the first sealing boss and the second sealing boss are made of elastic material.

[0011] Furthermore, the heat-conducting plate is provided with a flow guide groove and a connecting edge, the connecting edge extending out of the edge of the heat-conducting plate and extending along the circumference of the heat-conducting plate; the connecting edge is connected to the sealing element; The channel wall is provided with a guiding surface, which is used to guide water flow into the channel.

[0012] Furthermore, the leak-proof bottle warmer also includes a bottle warmer frame, which has a first snap-fit ​​part and a second snap-fit ​​part on the sealing baffle. The bottle warmer frame is connected to the second snap-fit ​​part by engaging with the first snap-fit ​​part.

[0013] Furthermore, the first snap-fit ​​portion includes a snap-fit ​​groove segment that extends through the bottle warmer; the second snap-fit ​​portion includes a buckle that snaps into the snap-fit ​​groove segment.

[0014] Furthermore, the side of the sealing baffle is provided with a limiting buckle, and the side of the bottle warmer is provided with a limiting groove. The limiting groove includes a first groove segment and a second groove segment.

[0023] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0024] See Figures 1 to 11 This utility model discloses a leak-proof bottle warmer, including a bottle warmer shell 10, a base 20, and a sealing element 30. The bottle warmer shell 10 is provided with a bottle warming cavity 11 and a sealing baffle 12. The sealing baffle 12 is located on the inner side of the bottom end of the bottle warming cavity 11 and extends circumferentially along the bottle warming cavity 11. The base 20 is provided with a mounting cavity 221, and a heating element 60 is provided in the mounting cavity 221. The top end of the mounting cavity 221 is covered with a heat-conducting plate 40. The bottle warmer shell 10 is detachably mounted on the base 20 and surrounds the outer periphery of the heat-conducting plate 40. At the same time, a first sealing boss 31 is provided at the top end of the sealing element 30, and a second sealing boss 32 is provided on the outer side wall of the sealing element 30. The sealing element 30 surrounds the mounting cavity 221 and the outer periphery of the heat-conducting plate 40. The first sealing boss 31 is used to seal against the sealing baffle 12. The second sealing boss 32 is used to seal against the inner side wall of the bottle warming cavity 11.

[0025] Based on the above structure, during assembly, after the heating element 60 is placed in the mounting cavity 221, the heat-conducting plate 40 is sealed to the opening 5211 of the mounting cavity 221, and the sealing element 30 is installed around the outer periphery of the heat-conducting plate 40. Utilizing the elastic deformation characteristics of the sealing element 30, the gap between the cavity wall of the mounting cavity 221 and the heat-conducting plate 40 is filled, reducing the risk of water in the milk warming cavity 11 seeping into the interior of the mounting cavity 221 along the gap, and reducing the occurrence of water flowing into the mounting cavity 221 from the milk warming cavity 11, thereby reducing the probability of safety hazards such as leakage and short circuit.

[0026] In addition, a sealing baffle 12 is provided on the inner side of the bottom end of the milk warming cavity 11 (that is, the end near the heat conduction plate 40). The sealing baffle 12 extends circumferentially along the milk warming cavity 11. After the milk warming shell 10 and the base 20 are detachably assembled, the bottom end of the milk warming cavity 11 and the first sealing boss 31 at the top of the sealing member 30 are tightly fitted together. The first waterproof barrier is formed by the interference fit. When water is introduced into the milk warming cavity 11, the presence of the first sealing boss 31 can block the water flow and reduce the risk of water seeping out from the gap between the bottom end of the milk warming cavity 11 and the base 20.

[0027] Even in extreme cases, if a small amount of moisture breaches the contact interface between the first sealing boss 31 and the sealing baffle 12, the overflowing water will flow downwards along the outer peripheral wall of the seal 30 until it encounters the second sealing boss 32. Because the second sealing boss 32 forms a secondary seal against the inner wall of the bottle warming chamber 11, the residual moisture is intercepted using a stepped sealing structure, achieving progressive protection against leakage risks through double sealing. This reduces the probability of water overflow, improves the waterproof and leak-proof performance of the bottle warmer, and thus reduces the occurrence of equipment malfunctions or short circuits caused by leakage.

[0028] Preferably, the sealing element 30 in this embodiment is made of elastic materials such as silicone or rubber. During assembly, when the sealing element 30 is installed around the outer periphery of the heat-conducting plate 40, it can undergo elastic compression under external force, tightly fitting the irregular gap between the cavity wall of the mounting cavity 221 and the heat-conducting plate 40, thus forming a good sealing effect. Even if slight displacement occurs between components due to vibration and temperature changes during long-term use of the bottle warmer, the self-recovery properties of the elastic material can maintain the sealing state, improving the waterproof and leak-proof performance of the bottle warmer.

[0029] Furthermore, the first sealing boss 31 and the second sealing boss 32 can be ribbed structures made of silicone or rubber materials, which can achieve an interference fit with the sealing baffle 12, the inner peripheral wall of the bottle warming chamber 11, and the base 20 through their own elasticity. This tight compression contact not only improves the sealing effect, but also effectively blocks water flow when the bottle warmer is tilted or shaken, forming multiple dynamic waterproof barriers.

[0030] More specifically, the heating element 60 in this embodiment can be selected from existing PTC thermistor heating elements, ceramic heating plates, or electromagnetic heating coils and other heating devices.

[0031] Furthermore, the sealing baffle 12 is provided with a sealing groove 121, which extends circumferentially along the sealing baffle 12. The first sealing boss 31 extends into the sealing groove 121 and abuts against the groove wall of the sealing groove 121.

[0032] Specifically, after the first sealing protrusion 31 extends into the sealing groove 121, the water flow needs to successively break through the side wall and bottom wall of the sealing groove 121 and the multiple contact surfaces of the first sealing protrusion 31 to form a "labyrinth-like" sealing structure. This significantly increases the water penetration resistance, significantly reduces the probability of leakage, further reduces the possibility of water overflowing from the inside of the warm milk cavity 11, and improves the waterproof and leak-proof effect.

[0033] More specifically, at least two first sealing protrusions 31 are provided. The design of distributing at least two first sealing protrusions 31 radially at intervals on the sealing member 30 creates multiple waterproof barriers. When water in the warming chamber 11 attempts to leak from the connection between the bottom of the warming chamber 11 and the base 20, it needs to break through the contact interface between the multiple first sealing protrusions 31 and the sealing baffle 12 in sequence. Each first sealing protrusion 31 becomes an independent waterproof barrier, greatly increasing the difficulty of water penetration and effectively reducing the risk of water leakage.

[0034] Furthermore, the spaced-apart second sealing bosses 32 extend the water seepage path. After water overflows from the gap between the first sealing boss and the sealing baffle 12, it must detour around the surface of the seal 30 before encountering the obstruction of the next first sealing boss 31. This tortuous path design significantly increases the resistance to water leakage and reduces the risk of leakage. Even if a first sealing boss 31 experiences slight failure due to assembly errors or long-term use, subsequent first sealing bosses 31 can still continue to perform their waterproofing function, enhancing the redundancy of the sealing structure.

[0035] Furthermore, at least two second sealing bosses 32 are provided, and the two second sealing bosses 32 are distributed at intervals in the axial direction of the seal 30.

[0036] Specifically, when water in the warming chamber 11 passes the first sealing protrusion 31 and attempts to leak through the gap between the side wall and the seal 30, due to the presence of multiple second sealing protrusions 32, the water flow needs to break through the sealing interface between the multiple layers of second sealing protrusions 32 and the inner side wall of the warming chamber 11. Each layer of second sealing protrusions 32 can independently intercept the water flow, just like setting up multiple "defense lines", which further improves the overall waterproof performance and effectively reduces the probability of water seeping out along the gaps in the side wall.

[0037] More specifically, the axially spaced protrusions significantly enhance the ability to prevent lateral leakage. Even if a small amount of water breaches the seal between the upper second sealing protrusion 32 and the side wall, it will be blocked again by the lower second sealing protrusion 32 as it flows downwards. This stepped sealing structure forces the water flow path to become tortuous and complex, increasing leakage resistance and reducing the possibility of water overflowing from the side wall of the bottle warming chamber 11. At the same time, when the bottle warmer encounters extreme situations such as shaking or tilting, the multiple second sealing protrusions 32 work together to better resist the lateral pressure generated by the inertia of the water flow, improving the sealing effect.

[0038] Furthermore, the base 20 includes a base shell 21 and a mounting base 22. A mounting cavity 221 is formed in the mounting base 22, and the base shell 21 covers the outer periphery of the mounting base 22. The mounting base 22 is provided with a connecting groove 222. The bottom of the sealing member 30 is provided with a connecting ring 33, which extends out of the edge of the sealing member 30 and extends circumferentially along the sealing member 30. The sealing member 30 is installed in the connecting groove 222 through the connecting ring 33, and the connecting ring abuts against the inner wall of the connecting groove 222. The inner side wall of the base shell 21 is provided with a pressing arm 211, which extends circumferentially along the base shell 21. The pressing arm 211 is used to extend into the connecting groove 222 and press the connecting ring 33 after it is installed in the connecting groove 222.

[0039] Specifically, the connecting ring 33 at the bottom of the seal 30 is positioned by the connecting groove 222 on the mounting base 22. After the connecting ring 33 extends circumferentially and is embedded in the connecting groove 222, the groove wall of the connecting groove 222 can constrain the seal 30 in the radial and axial directions, reducing the probability of displacement of the seal 30.

[0040] Furthermore, after the connecting ring 33 is installed in the connecting groove 222, the top pressure arm 211 extends circumferentially into the groove and presses the connecting ring 33, forcing the connecting ring 33 to undergo elastic deformation, further filling the tiny gap between the connecting groove 222 and the connecting ring 33, forming a tight physical seal. Compared to simple embedding installation, this effectively improves the waterproof performance between the seal 30 and the base 20.

[0041] It should be noted that the connecting ring 33 in this embodiment can also be made of existing elastic materials such as silicone or rubber to improve the sealing effect of the entire sealing element 30.

[0042] Furthermore, the heat-conducting plate 40 is provided with a flow guide groove 41 and a connecting edge 42. The connecting edge 42 extends out of the edge of the heat-conducting plate 40 and extends along the circumference of the heat-conducting plate 40. The connecting edge 42 is connected to the sealing member 30. The groove wall of the flow guide groove 41 is provided with a flow guide surface 411, which is used to guide water flow into the flow guide groove 41.

[0043] Specifically, the wall of the guide channel 41 is designed as a slope or an arc surface so that a guide surface 411 is formed inside the guide channel 41. In this way, even if water accidentally enters the contact surface between the seal 30 and the heat conduction plate 40, the water will flow into the guide channel 41 under the guidance of the guide surface 411 (sloping or arc surface), so that the water can be concentrated and guided into the guide channel 41 before entering the mounting cavity 221, reducing the risk of water overflowing to the outer periphery.

[0044] Furthermore, since the connecting edge 42 extends from the heat-conducting plate 40 and extends circumferentially along the heat-conducting plate 40, when the connecting edge 42 is tightly connected to the seal 30, it is equivalent to building a physical barrier around the edge of the heat-conducting plate 40. When the seal 30 undergoes slight deformation due to thermal expansion and contraction or external force, the connecting edge 42 can maintain the initial installation position of the seal 30 through rigid support, reducing the risk of gaps caused by displacement at the sealing interface and improving the stability of the structure. At the same time, even if a small amount of water crosses the guide groove 41, it will flow along the end face of the connecting edge 42 to the seal 30, and will not flow towards the mounting cavity 221, further reducing the risk of water entering the mounting cavity 221.

[0045] Furthermore, the leak-proof bottle warmer also includes a bottle warmer frame 50, which has a first snap-fit ​​part and a second snap-fit ​​part on the sealing baffle 12. The bottle warmer frame 50 is connected by snap-fitting the first snap-fit ​​part and the second snap-fit ​​part.

[0046] Specifically, the bottle warmer 50 is connected to the second snap-fit ​​part on the sealing baffle 12 through the engagement of the first snap-fit ​​part. During installation, the user only needs to align the first snap-fit ​​part of the bottle warmer 50 with the second snap-fit ​​part of the sealing baffle 12 and press or rotate it to quickly complete the installation. Compared with traditional methods such as screw fixing, the assembly time is greatly shortened, and it is also easy to disassemble and clean.

[0047] It should be noted that the first snap-fit ​​part can be a slot or a latch on the bottle warmer 50, and the second connecting part can be a buckle 122 or a latch block or similar structure corresponding to the sealing baffle 12. During assembly, align the buckle 122 or latch block with the latch and press lightly to quickly complete the installation.

[0048] Preferably, in this embodiment, the first snap-fit ​​part includes a snap-fit ​​groove section 51 that passes through the bottle warmer 50, and the second snap-fit ​​part includes a buckle 122. During assembly, the buckle 122 is aligned with the snap-fit ​​groove section 51, and the bottle warmer 50 is gently pressed so that the buckle 122 snaps into the snap-fit ​​groove section 51, thereby achieving quick installation.

[0049] Furthermore, the side of the sealing baffle 12 is also provided with a limiting buckle 123, and the side of the bottle warmer 50 is provided with a limiting groove 52. The limiting groove 52 includes a first groove segment 521 and a second groove segment 522. The first groove segment 521 extends along the axial direction of the sealing baffle 12, and the second groove segment 522 extends along the circumferential direction of the sealing baffle 12. The first groove segment 521 and the second groove segment 522 are in communication. The first groove segment 521 has an opening 5211. The limiting buckle 123 extends into the first groove segment 521 through the opening 5211. The limiting buckle 123 is used to engage with the second groove segment 522 when the bottle warmer 50 rotates.

[0050] Specifically, the first groove segment 521 of the limiting groove 52 extends axially along the sealing baffle 12, providing a clear installation guide path for the bottle warmer 50. During assembly, the user only needs to align the limiting groove 52 on the side of the bottle warmer 50 with the limiting buckle 123 of the sealing baffle 12, and slide it easily along the axial direction to complete the initial installation. This reduces the alignment difficulties caused by angular deviations in traditional installation methods and lowers the difficulty of operation.

[0051] After the bottle warmer 50 slides down into place along the first groove 521, the user rotates it to engage the limit buckle 123 into the second groove 522. The circumferentially extending structure of the second groove 522 creates a mechanical locking effect, firmly fixing the bottle warmer 50 to the sealing baffle 12. This effectively reduces the possibility of the bottle warmer 50 falling off due to accidental collisions, shaking, or accidental user contact. Thus, the engagement of the first and second locking parts creates a double lock between the bottle warmer 50 and the sealing baffle 12, further enhancing the stability of the bottle warmer 50.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
