Description

Technical Field

[0001] This invention relates to the field of beverage preparation equipment technology, and in particular to a liquid heating device. Background Technology

[0002] As people's living standards improve, consumers are demanding higher and higher levels of health and convenience in drinking water. As a water treatment device that can filter and purify water according to usage requirements and provide multiple water temperature options, water purifiers are gaining increasing recognition and favor from consumers.

[0003] Existing water dispensers and electric kettles generally use a kettle coupler structure. The coupler is connected vertically, and the coupler on the water dispenser is directly opposite the water spout. When or after use, water droplets from the spout will drip directly into the coupler, which can easily cause short circuits or leakage problems in the water dispenser. Summary of the Invention

[0004] Therefore, it is necessary to provide a liquid heating device that is waterproof, relatively convenient to use, and safe to operate, in order to address the above-mentioned problems.

[0005] A liquid heating device includes a main unit and an electric kettle. The electric kettle is mounted on the main unit and electrically connected to it. The main unit includes: a body; a water outlet assembly mounted on the top of the body; a water tank mounted on the side of the body away from the water outlet assembly, with the water outlet assembly connected to the water tank via a water passage; a first coupler mounted on the side wall of the body, electrically connected to the body, and on the same side as the electric kettle, and capable of telescopic movement relative to the body; a water receiving box mounted on the bottom of the body, on the same side as the water outlet assembly, and opposite to it; the electric kettle mounted on the water receiving box, capable of sliding relative to the water receiving box in the same direction as the telescopic movement of the first coupler; and a second coupler mounted on the electric kettle, with the first coupler electrically connected to the second coupler.

[0006] This application discloses a liquid heating device. The main unit can be used to prepare purified and filtered drinking water. An electric kettle is installed on the main unit, which can directly supply filtered water to the kettle. The main unit can also be powered on the kettle, allowing it to heat water, thus enabling it to be used as a health-preserving kettle. A water outlet assembly is located on the top of the unit, with the spout facing downwards, opposite the kettle and the water container. A water tank is located on the unit for water storage and multiple uses. The water tank is connected to the water outlet assembly via an internal water passage and pump. When the unit starts, water from the tank is delivered to the water outlet assembly. A drip tray catches dripping water from the water outlet assembly, preventing spillage onto the countertop or floor. A first coupler is located on the side wall of the unit and is compatible with a second coupler on the kettle. Optionally, the first and second couplers can be magnetically connected. Preferably, the first and second couplers are connected by a magnetic connection. The device uses a socket-type electrical connection. The first coupler is located on the side of the unit near the electric kettle, and it is positioned relatively low on the unit. By placing the first coupler on the side wall, residual water droplets from the spout can be prevented from falling onto the first coupler and causing short circuits or open circuits, thus improving safety. Compared to traditional bottom coupling, this liquid heating device does not require lifting the electric kettle when it needs to be removed; it can be simply moved horizontally. This avoids the top of the electric kettle colliding with the water outlet component, improving the user experience and preventing liquid spillage due to collisions.

[0007] The first coupler can extend and retract relative to the body. When the first coupler extends out of the body, it is electrically connected to the second coupler, and the body is electrically connected to the electric kettle, allowing the kettle to heat up. When the first coupler retracts into the body, it separates from the second coupler, de-energizing the body and the kettle, and the kettle stops working. The extension and retraction of the first coupler enables automatic power-off and separation, thereby improving safety and convenience.

[0008] In addition, the electric kettle can slide relative to the water inlet box, which is a foolproof design. By sliding the kettle relative to the water inlet box, the user can fix the electric kettle in place. At the same time, the first coupler and the second coupler will naturally align and plug in, saving the user the trouble of manually aligning the couplers and turning on the power, thus improving the user experience.

[0009] In some embodiments, the first coupler has a first position and a second position relative to the body. When the first coupler is in the first position, the first coupler is electrically connected to the second coupler; when the first coupler is in the second position, the first coupler is separated from the second coupler.

[0010] The aforementioned liquid heating device is further defined as follows: Specifically, the first coupler has two working positions within the body. In the first position, the first coupler extends out of the body and plugs into the second coupler to achieve electrical connection. At this time, the electric kettle can heat the water or beverage inside the kettle. When heating stops, the first coupler retracts back into the body, which is the second position.

[0011] In some embodiments, the first coupler includes a male seat assembly and a drive assembly, which are electrically connected to the body, respectively. The male seat assembly is also electrically connected to a second coupler. The drive assembly and the male seat assembly are drively connected, and the drive assembly can drive the male seat assembly to extend and retract relative to the body.

[0012] The aforementioned liquid heating device further specifies that the extension and retraction of the first coupler is achieved by a motor drive. The first coupler includes a male connector assembly and a drive assembly. The drive assembly is used to drive the male connector assembly to extend and retract within the machine body. The second coupler serves as a female connector and is electrically connected to the male connector assembly.

[0013] In some embodiments, the male seat assembly includes a male seat body and a rack. The two ends of the male seat body are electrically connected to the machine body and a second coupler, respectively. The rack is disposed on the male seat body. The drive assembly includes a motor and a gear. The gear is disposed on the rotating shaft of the motor and meshes with the rack.

[0014] In this embodiment, the male seat body is used to electrically connect with the second coupler. The rack is fixedly connected to the male seat body and can mesh with the gear. The rack is long and narrow. When the motor starts, the gear fixed on the rotating shaft will rotate forward or backward, thereby driving the long rack to move forward or backward, thus allowing the male seat body to extend and retract on the machine body.

[0015] In some embodiments, the electric kettle further includes a cup body, a base, a heating element, and a lid. The lid is placed on the cup body, the base is placed at the bottom of the cup body, the heating element is placed inside the base, and a second coupler is at least partially placed inside the base. The heating element is electrically connected to the second coupler.

[0016] The aforementioned liquid heating device further specifies that the electric kettle also includes a cup body, a base, a heating element, and a cup lid. The heating element and the second coupler are both located in the mounting cavity of the base and are electrically connected. When the second coupler is connected to the first coupler and energized, the heating element can work to heat the liquid in the cup body.

[0017] In some embodiments, the cup lid has a water inlet that is connected to the cup body and is positioned opposite to the water outlet component.

[0018] In this embodiment, by opening a water inlet on the cup lid and making the water inlet and the spout coaxial, water can be poured into the cup without opening the lid, eliminating the hassle of putting the lid back on after filling the cup and improving the user experience.

[0019] In some embodiments, the drip tray and the electric kettle slide relative to each other in a sliding manner.

[0020] The aforementioned liquid heating device also specifies that the limiting sliding between the water tray and the electric kettle is achieved in the form of a slide rail. This design makes the operation of the water tray and the electric kettle simple and convenient, improving the user experience.

[0021] In some embodiments, one or more guide grooves are provided on the bottom wall of the base, and one or more guide protrusions are provided on the side of the water tray near the electric kettle, with the guide grooves and guide protrusions being adapted to each other.

[0022] In this embodiment, multiple guide grooves are provided on the bottom wall of the base near the water tray, and multiple guide protrusions are provided on the side of the water tray near the electric kettle. The guide grooves and guide protrusions can slide relative to each other, and the direction of the sliding is the same as the direction of the extension and retraction of the first coupler. Thus, when the user pushes the electric kettle into the water tray along the slide rail, the second coupler is already aligned with the first coupler and can be directly plugged in to achieve electrical connection. This eliminates the need for the user to manually align the socket, improving the convenience of the product.

[0023] In some embodiments, the water receiving tray includes a grid and a tray body, the grid and the tray body are detachably connected, the grid and the tray body enclose a water receiving cavity, and one or more guide protrusions are provided on the grid.

[0024] In this embodiment, the water receiving tray is formed by a grille and a tray body. The grille and the tray body are detachably connected. When the water in the water receiving cavity is almost full, the grille can be removed to facilitate the removal of water from the tray body. The grille is the side of the water receiving tray that directly contacts the electric kettle. Therefore, multiple guide protrusions are provided on the grille to achieve limited sliding.

[0025] In some embodiments, the water tank includes a water tank body and a filter. The water tank body has a water storage cavity, the filter is disposed on the water tank body, and the filter is at least partially located in the water storage cavity. The water storage cavity communicates with the inner cavity of the filter, and the inner cavity of the filter communicates with the water outlet assembly water passage.

[0026] The aforementioned liquid heating equipment further specifies that by installing a filter in the water storage chamber of the water tank body to filter the water in the storage chamber, the water entering the water outlet component meets the standard for direct drinking, thereby improving the safety and hygiene of the water output from the liquid heating equipment.

[0039] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0041] Some embodiments of the liquid heating device of the present invention are described below with reference to the accompanying drawings.

[0042] like Figures 1 to 3 As shown, a liquid heating device includes a main unit 100 and an electric kettle 200. The electric kettle 200 is mounted on the main unit 100 and electrically connected to the main unit 100. The main unit 100 includes: a body 110; a water outlet assembly 120 mounted on the top of the body 110; a water tank 130 mounted on the side of the body 110 away from the water outlet assembly 120, with the water outlet assembly 120 connected to the water tank 130 via a water path; and a first coupler 140 mounted on the side wall of the body 110 and electrically connected to the body 110. The first coupler 140 is on the same side as the electric kettle 200, and can extend and retract relative to the body 100. The water receiving box 150 is located at the bottom of the body 110, and is on the same side as the water outlet assembly 120, and is positioned opposite to the water outlet assembly 120. The electric kettle 200 is mounted on the water receiving box 150, and can slide relative to the water receiving box 150 in a limited manner. The direction of sliding is the same as the extension and retraction direction of the first coupler 140. The electric kettle 200 is provided with a second coupler 210, and the first coupler 140 can be electrically connected to the second coupler 210.

[0043] This application discloses a liquid heating device. The main unit 100 can be used to prepare purified and filtered drinking water. An electric kettle 200 is installed on the main unit 100. The main unit 100 can directly supply filtered water to the electric kettle 200. The main unit 100 can be powered on the electric kettle 200 so that the electric kettle 200 can heat water. Therefore, the electric kettle 200 can also be used as a health-preserving kettle. The water outlet assembly 120 is located on the top of the body 110, with the spout facing downwards, opposite the electric kettle 200 and the water dispenser 150. The water tank 130 is located on the body 110 for water storage and multiple uses. The water tank 130 is connected to the water outlet assembly 120 via the internal water passages and pump of the body 110. When the body 110 is started, water from the cup in the water tank 130 is delivered to the water outlet assembly 120. The water tray 150 is used to collect water dripping from the water outlet assembly 120, preventing liquid from splashing onto the countertop or floor. The first coupler 140 is located on the side wall of the body 110 and is adapted to the second coupler 210 on the electric kettle 200. Optionally, the first coupler 110 and the second coupler 210 can be a magnetic electrical connection, preferably... The first coupler 110 and the second coupler 210 are socket-type electrical connections. The first coupler 110 is located on the side of the body 110 near the electric kettle 200, and the first coupler 110 is located relatively low on the body 110. By placing the first coupler 110 on the side wall, residual water droplets from the spout can be prevented from falling onto the first coupler 110, thus avoiding short circuits or open circuits and improving safety. Compared to traditional bottom coupling, this liquid heating device does not require lifting the electric kettle 200 when it needs to be removed; it can be removed simply by sliding it horizontally. This avoids the top of the electric kettle 200 colliding with the water outlet assembly 120, improving the user experience and preventing liquid from spilling due to collisions.

[0044] The first coupler 140 can extend and retract relative to the body 110. When the first coupler 110 extends out of the body 110, the first coupler 140 is electrically connected to the second coupler 210. At this time, the body 110 is electrically connected to the electric kettle 200, and the electric kettle 200 can heat water. When the first coupler 140 retracts into the body 110, the first coupler 140 is separated from the second coupler 210. At this time, the body 110 is de-energized from the electric kettle 200, and the electric kettle 200 stops working. Through the extension and retraction of the first coupler 140, automatic power-off separation can be achieved, thereby improving the safety and convenience of use.

[0045] Furthermore, the electric kettle 200 can slide relative to the water inlet box 150, which is a foolproof design. By sliding the kettle 200 to the water inlet box 150, the user can fix the electric kettle 200 to the water inlet box 150. At the same time, the first coupler 140 and the second coupler 210 are naturally aligned and plugged in, saving the user the trouble of manually aligning the couplers and turning on the power, thus improving the user experience.

[0046] like Figure 2 and Figure 3 As shown, the first coupler 140 has a first position and a second position relative to the body 110. When the first coupler 140 is in the first position, the first coupler 140 is electrically connected to the second coupler 210; when the first coupler 140 is in the second position, the first coupler 140 is separated from the second coupler 210.

[0047] The aforementioned liquid heating device is further defined as follows: Specifically, the first coupler 140 has two working positions within the body 110. In the first position, the first coupler 140 extends out of the body 110 and plugs into the second coupler 210 to achieve electrical connection. At this time, the electric kettle 200 can heat the water or beverage inside the kettle. When heating stops, the first coupler 140 retracts back into the body 110, which is the second position.

[0048] like Figure 1 and Figure 6 As shown, the first coupler 140 includes a male seat assembly 141 and a drive assembly 142. The male seat assembly 141 and the drive assembly 142 are electrically connected to the body 110, respectively. The male seat assembly 141 is also electrically connected to the second coupler 210. The drive assembly 142 and the male seat assembly 141 are connected by a transmission. The drive assembly 142 can drive the male seat assembly 141 to extend and retract relative to the body 110.

[0049] The aforementioned liquid heating device further specifies that the extension and retraction of the first coupler 140 is achieved by a motor drive. The first coupler 140 includes a male seat assembly 141 and a drive assembly 142. The drive assembly 142 is used to drive the male seat assembly 141 to extend and retract within the body 110. The second coupler 210 is electrically connected to the male seat assembly 141 as a female seat.

[0050] like Figure 3 and Figure 6 As shown, the male seat assembly 141 includes a male seat body 1411 and a rack 1412. The two ends of the male seat body 1411 are electrically connected to the machine body 110 and the second coupler 210, respectively. The rack 1412 is disposed on the male seat body 1411. The drive assembly 142 includes a motor 1421 and a gear 1422. The gear 1422 is disposed on the rotating shaft of the motor 1421 and meshes with the rack 1412.

[0051] In this embodiment, the male seat body 1411 is used to electrically connect with the second coupler 210. The rack 1412 is fixedly connected to the male seat body 1411, and the rack 1412 can mesh with the gear 1422. The rack 1412 is long and narrow. When the motor 1421 starts, the gear 1422 fixed on the rotating shaft will rotate forward or backward, thereby driving the long rack 1412 to move forward or backward, and thus causing the male seat body 1411 to extend and retract on the body 110.

[0052] like Figure 3 and Figure 4 As shown, the electric kettle 200 also includes a cup body 220, a base 230, a heating element 240, and a lid 250. The lid 250 covers the cup body 220, the base 230 is disposed at the bottom of the cup body 220, the heating element 240 is disposed inside the base 230, and the second coupler 210 is at least partially disposed inside the base 230. The heating element 240 is electrically connected to the second coupler 210.

[0053] The aforementioned liquid heating device further specifies that the electric kettle 200 also includes a cup body 220, a base 230, a heating element 240, and a cup lid 250. The heating element 240 and the second coupler 210 are both disposed in the mounting cavity of the base 230 and are electrically connected. When the second coupler 210 is connected to the first coupler 140 and energized, the heating element 240 can work to heat the liquid in the cup body 220.

[0054] like Figure 2 and Figure 4 As shown, the cup lid 250 has a water inlet 2501, which is connected to the cup body 220 and is positioned opposite to the water outlet component 120.

[0055] In this embodiment, by opening a water inlet 2501 on the cup lid 250 and making the water inlet 2501 coaxial with the water outlet, water can be poured into the cup body 220 without opening the cup lid 250, eliminating the hassle of putting the lid back on after filling the cup and improving the user experience.

[0056] like Figure 3 and Figure 5 As shown, the water tray 150 and the electric kettle 200 slide relative to each other via a sliding rail.

[0057] The aforementioned liquid heating device also specifies that the limiting sliding between the water tray 150 and the electric kettle 200 is achieved in the form of a slide rail. This design makes the operation of the water tray 150 and the electric kettle 200 simple and convenient, improving the user experience.

[0058] like Figures 3 to 5As shown, one or more guide grooves 231 are provided on the bottom wall of the base 230, and one or more guide protrusions 1501 are provided on the side of the water receiving tray 150 near the electric kettle 200. The guide grooves 231 are adapted to the guide protrusions 1501.

[0059] In this embodiment, multiple guide grooves 231 are provided on the bottom wall of the base 230 near the water tray 105, and multiple guide protrusions 1501 are provided on the side of the water tray 150 near the electric kettle 200. The guide grooves 231 and the guide protrusions 1501 can slide relative to each other, and the direction of the sliding relative to each other is the same as the direction of the extension and retraction of the first coupler 140. Thus, when the user pushes the electric kettle 200 towards the inside of the water tray 150 along the direction of the slide rail, the second coupler 210 is already aligned with the first coupler 140 and can be directly plugged in to achieve electrical connection. This eliminates the need for the user to manually align the socket, improving the convenience of the product.

[0060] like Figure 5 As shown, the water receiving tray 150 includes a grille 151 and a tray body 152. The grille 151 and the tray body 152 are detachably connected. The grille 151 and the tray body 152 enclose a water receiving cavity. One or more guide protrusions 1501 are provided on the grille 151.

[0061] In this embodiment, the water receiving tray 150 is formed by a grille 151 and a tray body 152. The grille 151 and the tray body 152 are detachably connected. When the water in the water receiving cavity is almost full, the grille 151 can be removed to facilitate the removal of water from the tray body 152. The grille 151 is the side of the water receiving tray 150 that directly contacts the electric kettle 200. Therefore, multiple guide protrusions 1501 are provided on the grille 151 to achieve limited sliding.

[0062] like Figure 2 As shown, the water tank 130 includes a water tank body 131 and a filter 132. The water tank body 131 is provided with a water storage chamber 1301. The filter 132 is disposed on the water tank body 131 and is at least partially located in the water storage chamber 1301. The water storage chamber 1301 is connected to the inner cavity of the filter 132. The inner cavity of the filter 132 is connected to the water outlet assembly 120.

[0063] The aforementioned liquid heating device further specifies that by installing a filter 132 in the water storage chamber 1301 of the water tank body 131 to filter the water in the water storage chamber 1301, the water entering the water outlet component 120 meets the standard of being directly drinkable, thereby improving the safety and hygiene of the water output from the liquid heating device.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
