Description

Technical Field

[0001] This invention relates to the field of electric hot water bottle technology, specifically to a water connector, an electrical coupler, and an electric hot water bottle. Background Technology

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] Currently, electric couplers are widely used in electric kettles. They consist of an upper coupler and a lower coupler, both equipped with multiple ring-shaped metal electrodes. Electrical connection is established by inserting the upper coupler into the lower coupler and the contact of the corresponding metal electrodes. This electric coupler not only allows for the separation of the upper and lower couplers to separate the kettle body from the base, but also allows the kettle body to be inserted from either direction and fitted to the base, making it very convenient to use.

[0004] As people's living standards continue to improve, consumers have higher requirements for electric kettles, hoping for automatic control of water dispensing. To address this, some manufacturers have installed an upper inlet pipe in the central opening of the upper coupler, with an upper valve core connected to a spring inside the upper inlet pipe. Similarly, a lower inlet pipe is installed in the central opening of the lower coupler, with a lower valve core connected to a spring inside the lower inlet pipe. Thus, when the upper and lower couplers are coupled, the upper and lower valve cores abut against each other, connecting the upper and lower inlet channels and allowing water to flow. When the couplers are separated, both the upper and lower valve cores move back via the springs to seal the upper and lower inlet channels respectively. However, the above-mentioned setup still has the following problems: First, the upper valve core achieves the opening and closing of the upper water inlet channel through spring reset movement, which increases the difficulty of installing the upper valve core; second, the upper and lower water inlet channels are connected by the upper and lower valve cores pushing against each other, making it difficult to control the elastic force and direction of the two springs, and the springs are prone to twisting or deformation, leading to elastic failure; finally, the sealing between the upper valve core and the upper water inlet pipe, and between the lower valve core and the lower water inlet pipe, is also difficult to control. If the sealing is not tight, it will cause water leakage and may even burn out electrical components.

[0005] Therefore, how to provide an electric kettle with a simple water outlet structure and convenient control operation is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In order to overcome the defects described in the prior art, the present invention provides a water connector, an electrical coupler, and an electric hot water bottle to solve at least one of the above-mentioned technical problems.

[0007] The technical solution adopted by this invention to solve its problem is:

[0008] A water connector includes an upper water inlet assembly and a lower water inlet assembly, wherein:

[0009] The upper water inlet assembly includes an upper water inlet pipe forming an upper water inlet channel, a first sealing ring disposed at the bottom of the upper water inlet channel, and an upper valve core movably disposed within the upper water inlet channel. The upper valve core moves downward under the action of gravity and abuts against the port of the first sealing ring to seal the upper water inlet channel.

[0010] The lower water inlet assembly includes a lower water inlet pipe forming a lower water inlet channel and a shaft disposed within the lower water inlet channel. When the upper water inlet pipe extends into the lower water inlet channel and reaches a certain position, the upper valve core is pushed up by the shaft to open the upper water inlet channel.

[0011] Furthermore, the bottom of the upper water inlet pipe is provided with a first water outlet that connects to the upper water inlet channel, and the first sealing ring is disposed in the upper water inlet channel and close to the first water outlet.

[0012] Furthermore, the top of the upper water inlet pipe is provided with a first water inlet that connects to the upper water inlet channel; the upper water inlet assembly also includes a filter screen covered on the first water inlet, the filter screen includes a circular plate portion and a retaining portion surrounding the bottom of the outer edge of the circular plate portion, the circular plate portion is provided with a plurality of small holes, and the connection between the circular plate portion and the retaining portion is provided with a plurality of large holes.

[0013] Furthermore, the lower water inlet assembly also includes a second sealing ring disposed at the top of the lower water inlet channel and a first lower valve core movably disposed within the lower water inlet channel; the lower water inlet channel is also provided with a first elastic element, which, under the elastic force of the first elastic element, can drive the first lower valve core to abut against the port of the second sealing ring to seal the lower water inlet channel;

[0014] When the upper water inlet pipe extends into the lower water inlet channel, the upper water inlet pipe abuts against the first lower valve core and drives it to move downward against the elastic force of the first elastic element to open the lower water inlet channel. When the upper valve core is lifted by the shaft, the upper water inlet channel and the lower water inlet channel are connected.

[0015] When the upper water inlet pipe extends into the lower water inlet channel, the outer wall of the upper water inlet pipe abuts against the inner wall of the second sealing ring to form a waterproof seal.

[0016] Furthermore, the top of the lower water inlet pipe is provided with a second water inlet that connects to the lower water inlet channel, and the second sealing ring is fitted onto the second water inlet.

[0017] Furthermore, it also includes a housing fitted around the outer periphery of the lower water inlet pipe, the top of the housing and the top of the lower water inlet pipe forming an installation groove, and the second sealing ring being engaged in the installation groove.

[0018] Furthermore, it also includes a baffle plate, a second lower valve core, and a third sealing ring disposed within the lower water inlet channel, wherein:

[0019] The partition plate has a second outlet that connects to the lower water inlet channel. The bottom of the shaft extends through the partition plate and connects to the second lower valve core. The third sealing ring is fitted onto the second lower valve core.

[0020] The shaft is also provided with a collar to form a stepped surface; a second elastic element is sleeved on the shaft, one end of the second elastic element abuts against the bottom of the collar, and the other end abuts against the partition plate; under the elastic force of the second elastic element, the shaft can be driven to move upward, thereby driving the second lower valve core to move upward so that the third sealing ring blocks the second outlet to form a seal;

[0021] When the upper water inlet pipe extends into the lower water inlet channel and drives the first lower valve core to move downward to a certain position, the first lower valve core abuts against the top of the shaft collar and drives the shaft to move downward against the elastic force of the second elastic element, thereby driving the second lower valve core and the third sealing ring to move downward to open the second water outlet.

[0022] Furthermore, the first elastic element is sleeved on the first lower valve core, with one end abutting against the first lower valve core and the other end abutting against the partition plate.

[0023] Furthermore, a second aspect of the present invention provides an electrical coupler, comprising an upper coupler, a lower coupler, and the aforementioned water connector, wherein:

[0024] The upper coupler has a first through hole in the middle, and the upper water inlet assembly is disposed at the first through hole;

[0025] The lower coupler has a second through hole in the middle, and the lower water inlet assembly is located at the second through hole.

[0026] Furthermore, a third aspect of the present invention provides an electric kettle, comprising a base, a shell disposed on the base, an inner liner disposed inside the shell, and the aforementioned electrocoupler, wherein:

[0027] The upper coupler is provided at the bottom of the inner liner, and the lower coupler is provided on the base.

[0028] Furthermore, it also includes a water pump installed in the base, the water inlet of the water pump being connected and in communication with the lower water inlet pipe;

[0029] A water outlet is also provided on one side of the top of the outer casing. The water outlet is connected to the water outlet of the water pump through a water pipe.

[0030] In summary, the water connector, electrical coupler, and electric kettle provided by this invention have the following beneficial effects:

[0031] (1) In the water connector of the present invention, when the upper water inlet pipe and the lower water inlet pipe are separated, the natural gravity of the upper valve core can be used to block the port of the first sealing ring to seal the upper water inlet channel, thereby preventing residual water in the upper water inlet channel from overflowing and dripping downwards. In addition, since the spring-upper valve core engagement method is eliminated, the use of springs is reduced and the structure for installing springs on the upper water inlet pipe and the upper valve core is avoided, greatly reducing the cost of accessories and production. Furthermore, the upper valve core is lifted by the shaft set in the lower water inlet pipe to open the upper water inlet channel, making the operation simple and easy to control.

[0032] (2) The water connector of the present invention, by opening several small holes in the circular plate portion of the filter screen, can filter out larger scale or solid particles, preventing them from entering the upper or lower water inlet pipe and causing blockage; by providing several large holes around the connection between the circular plate portion and the enclosure portion, water can flow into the upper water inlet pipe through the large holes, avoiding the formation of a water film on the small holes, which would prevent the water from flowing smoothly into the upper water inlet pipe. In addition, the air bubbles generated after the water in the upper and lower water inlet channels boils can also be discharged through the large holes.

[0033] (3) When the upper water inlet pipe and the lower water inlet pipe are separated, the first lower valve core can be driven to abut against the port of the second sealing ring under the elastic force of the first elastic element to seal the second water inlet of the lower water inlet channel, preventing the water remaining in the lower water inlet channel from overflowing and dripping into the base, thus avoiding water intrusion into the electrode and causing leakage hazard.

[0034] (4) In the water connector of the present invention, when the upper water inlet pipe is inserted into the lower water inlet channel, the outer side wall of the upper water inlet pipe abuts against the inner side wall of the second sealing ring to form a waterproof seal, preventing water leakage when the upper water inlet pipe is inserted into the lower water inlet channel, and further improving the sealing performance.

[0035] (5) When the upper water inlet pipe and the lower water inlet pipe are separated, the water connector of the present invention can drive the shaft to move upward under the elastic force of the second elastic element, thereby driving the second lower valve core to move upward so that the third sealing ring blocks the second water outlet to form a seal, preventing the water in the water pipe connected to the water outlet of the water pump from flowing back into the lower water inlet channel, further improving the sealing effect and reducing the probability of water leakage in the lower water inlet assembly.

Detailed Implementation

[0047] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0048] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0050] Example 1

[0051] See Figure 1-8 The present invention first provides a water connector, including an upper water inlet assembly 1 and a lower water inlet assembly 2. The upper water inlet assembly 1 includes an upper water inlet pipe 11 forming an upper water inlet channel, a first sealing ring 12 disposed at the bottom of the upper water inlet channel, and an upper valve core 13 movably disposed within the upper water inlet channel. The upper valve core 13 moves downward under the action of gravity and abuts against the port of the first sealing ring 12 to seal the upper water inlet channel; preferably, the upper valve core 13 is a steel ball. The lower water inlet assembly 2 includes at least a lower water inlet pipe 21 forming a lower water inlet channel and a shaft 22 disposed within the lower water inlet channel. When the upper water inlet pipe 11 extends into the lower water inlet channel and reaches a certain position, the upper valve core 13 is pushed up by the shaft 22 to open the upper water inlet channel. Figure 7 As shown.

[0052] Therefore, when the upper inlet pipe 11 and the lower inlet pipe 21 are separated, the natural gravity of the upper valve core 13 can be used to block the port of the first sealing ring 12 to seal the upper inlet channel, thereby preventing residual water in the upper inlet channel from overflowing and dripping downwards. Furthermore, by eliminating the spring-upper valve core 13 mechanism, the use of springs is reduced, and the structural design for mounting springs on the upper inlet pipe 11 and upper valve core 13 is avoided, significantly reducing component and production costs. In addition, the upper valve core 13 is lifted by the shaft 22 located inside the lower inlet pipe 21 to open the upper inlet channel, making operation simple and easy to control.

[0053] See Figure 2-3 Specifically, the top and bottom of the upper water inlet pipe 11 are respectively provided with a first water inlet 111 and a first water outlet 112 that connect to the upper water inlet channel. The first sealing ring 12 is disposed in the upper water inlet channel and close to the first water outlet 112. A filter screen 14 is also provided above the first water inlet 111. The filter screen 14 includes a circular plate portion 141 and a retaining portion 142 that is arranged around the bottom of the outer edge of the circular plate portion 141. The circular plate portion 141 is provided with a plurality of small holes 1411, and a plurality of large holes 1421 are arranged around the connection between the circular plate portion 141 and the retaining portion 142.

[0054] Therefore, when the upper water inlet assembly 1 is installed at the bottom of the inner liner 7 of the electric kettle, several small holes 1411 are made on the circular plate portion 141 of the filter screen 14, which can filter out larger scale or solid particles remaining in the water in the inner liner 7, preventing them from entering the upper water inlet pipe 11 or the lower water inlet pipe 21 and causing blockage. Because the diameter of the small holes 1411 is small, water at the bottom of the inner liner 7 easily forms a water film on the small holes 1411. When the water level at the bottom of the inner liner 7 is low, the water at the bottom of the inner liner 7 cannot flow smoothly into the upper water inlet channel through the small holes 1411. Therefore, several large holes 1421 are provided around the connection between the circular plate portion 141 and the baffle portion 142, allowing the water at the bottom of the inner liner 7 to flow smoothly into the upper water inlet pipe 11 through the large holes 1421. In addition, when the water at the bottom of the inner liner 7 is heated to a boiling state, the resulting air bubbles can also be smoothly discharged through the large holes 1421.

[0055] See Figure 4-5The lower water inlet assembly 2 also includes a second sealing ring 23 disposed at the top of the lower water inlet channel and a first lower valve core 24 movably disposed within the lower water inlet channel. Specifically, the top of the lower water inlet pipe 21 has a second water inlet 212 communicating with the lower water inlet channel, and the second sealing ring 23 is fitted onto the second water inlet 212; a partition 211 is disposed in the middle of the lower water inlet pipe 21, and a plurality of second water outlets 2111 communicating with the lower water inlet channel are arranged around the partition 211. In addition, a first elastic member 25 is disposed within the lower water inlet channel, and the top of the first lower valve core 24 has a downwardly extending flange 241. The first elastic member 25 is fitted onto the flange 241, and its top abuts against the first lower valve core 24, while its bottom abuts against the partition 211. Thus, under the elastic force of the first elastic member 25, the first lower valve core 24 can be driven to abut against the port of the second sealing ring 23 to seal the second water inlet 212 of the lower water inlet channel. Preferably, the first elastic element 25 is a spring.

[0056] In this embodiment, the first lower valve core 24 has a clearance hole in the middle for the shaft 22 to pass through.

[0057] Therefore, when the upper water inlet pipe 11 extends into the lower water inlet channel, the upper water inlet pipe 11 abuts against the first lower valve core 24 and drives it to move downward against the elastic force of the first elastic element 25 to open the lower water inlet channel. Figure 6 As shown; until the upper valve core 13 is lifted by the shaft 22, the upper water inlet channel is connected to the lower water inlet channel, as shown. Figure 7 As shown. When the upper water inlet pipe 11 extends into the lower water inlet channel, the outer wall of the upper water inlet pipe 11 abuts against the inner wall of the second sealing ring 23 to form a waterproof seal.

[0058] Therefore, when the lower water inlet assembly 2 is placed on the base 5 of the electric kettle and the upper water inlet pipe 11 is separated from the lower water inlet pipe 21, the elastic force of the first elastic element 25 can cause the first lower valve core 24 to abut against the port of the second sealing ring 23 to seal the second water inlet 212 of the lower water inlet channel, preventing residual water in the lower water inlet channel from overflowing and dripping into the base 5, thereby avoiding water intrusion into the electrodes and causing a risk of electric leakage. In addition, when the upper water inlet pipe 11 extends into the lower water inlet channel, the outer wall of the upper water inlet pipe 11 abuts against the inner wall of the second sealing ring 23 to form a waterproof seal, preventing water leakage when the upper water inlet pipe 11 extends into the lower water inlet channel, further improving the sealing performance.

[0059] In this embodiment, the lower water inlet assembly 2 further includes a housing 26 sleeved around the lower water inlet pipe 21. The top of the housing 26 and the top of the lower water inlet pipe 21 form an installation groove, and the second sealing ring 23 is engaged in the installation groove.

[0060] See also Figure 4-5 The lower water inlet assembly 2 also includes a second lower valve core 27 disposed within the lower water inlet channel and located below the partition plate 211, and a third sealing ring 28. The bottom of the shaft 22 extends through the partition plate 211 and connects to the second lower valve core 27, and the third sealing ring 28 is fitted onto the top of the second lower valve core 27. Specifically, the shaft 22 is also provided with a collar 221 to form a stepped surface, and the partition plate 211 has a protruding groove 2112 in the middle. In addition, the shaft 22 is also fitted with a second elastic member 29, one end of which abuts against the bottom of the collar 221, and the other end abuts against the bottom of the groove 2112 in the partition plate 211. Preferably, the second elastic member 29 is also a spring.

[0061] Therefore, under the elastic force of the second elastic element 29, the shaft 22 can be moved upward, thereby causing the second lower valve core 27 to move upward so that the third sealing ring 28 blocks several second outlets 2111 to form a seal. When the upper inlet pipe 11 extends into the lower inlet channel and causes the first lower valve core 24 to move downward to a certain position, the first lower valve core 24 abuts against the top of the shaft ring 221 and causes the shaft 22 to move downward against the elastic force of the second elastic element 29, thereby causing the second lower valve core 27 and the third sealing ring 28 to move downward to open the second outlets 2111, such as... Figure 8 As shown.

[0062] Therefore, when the lower water inlet assembly 2 is placed on the base 5 of the electric hot water bottle and the upper water inlet pipe 11 is separated from the lower water inlet pipe 21, under the elastic force of the second elastic element 29, the shaft 22 can be driven to move upward, thereby driving the second lower valve core 27 to move upward so that the third sealing ring 28 blocks the second water outlet 2111 to form a seal, preventing water in the water pipe connected to the water outlet of the water pump 9 from flowing back into the lower water inlet channel, further improving the sealing effect and reducing the probability of water leakage in the lower water inlet assembly 2.

[0063] Example 2

[0064] See also Figure 1-8 The second aspect of the present invention also provides an electrical coupler, including an upper coupler 3, a lower coupler 4, and the water connector in the first embodiment above. The upper coupler 3 has a first through hole in its middle, and the upper water inlet component 1 is disposed at the first through hole. The lower coupler 4 has a second through hole in its middle, and the lower water inlet component 2 is disposed at the second through hole.

[0065] Therefore, when the upper coupler 3 and the lower coupler 4 are separated, as Figure 1As shown, the upper valve core 13 in the upper water inlet assembly 1 moves downward under the action of natural gravity and blocks the port of the first sealing ring 12 to seal the upper water inlet channel; the first lower valve core 24 in the lower water inlet assembly 2 abuts against the port of the second sealing ring 23 under the elastic force of the first elastic member 25 to seal the second water inlet 212 of the lower water inlet channel; the second lower valve core 27 moves upward under the elastic force of the second elastic member 29 so that the third sealing ring 28 blocks the second water outlet 2111 to form a seal, thereby achieving the sealing of the upper water inlet channel and the lower water inlet channel respectively.

[0066] When the upper coupler 3 and the lower coupler 4 are coupled together, such as Figure 6-8 As shown, the upper water inlet pipe 11 in the upper water inlet assembly 1 extends into the lower water inlet channel of the lower water inlet assembly 2. Its operation process can be referred to the description in Embodiment 1, and will not be repeated here.

[0067] Example 3

[0068] See Figure 9 The third aspect of the present invention also provides an electric kettle, comprising a base 5, a shell 6 disposed on the base 5, an inner liner 7 disposed inside the shell 6, and the electric coupler described in Embodiment 2 above. The inner liner 7 has an upper coupler 3 at its bottom, and an upper water inlet assembly 1 at its center; the base 5 has a lower coupler 4, and a lower water inlet assembly 2 at its center.

[0069] In addition, it also includes a water pump 9 installed in the base 5, the water inlet end of which is connected and connected to the lower water inlet pipe 21; the top side of the housing 6 is also provided with a water outlet 8, which is connected and connected to the water outlet end of the water pump 9 through a water pipe.

[0070] Therefore, when the inner tank 7 is placed on the base 5, the upper coupler 3 and the lower coupler 4 are coupled together to achieve circuit conduction. At the same time, the upper water inlet component 1 in the upper coupler 3 and the lower water inlet component 2 in the lower coupler 4 cooperate to achieve water flow. When the water in the inner tank 7 boils, the boiling water in the inner tank 7 can be drawn out by the water pump 9 and transported to the water outlet 8 through the water pipe, thereby realizing automatic water dispensing.

[0071] In summary, the water connector, electrical coupler, and electric kettle provided by this invention have the following beneficial effects:

[0072] (i) In the water connector of the present invention, when the upper water inlet pipe 11 and the lower water inlet pipe 21 are separated, the natural gravity of the upper valve core 13 can be used to block the port of the first sealing ring 12 to seal the upper water inlet channel, thereby preventing residual water in the upper water inlet channel from overflowing and dripping downwards. In addition, since the spring-upper valve core 13 engagement method is eliminated, the use of springs is reduced and the structural setting for installing springs on the upper water inlet pipe 11 and the upper valve core 13 is avoided, greatly reducing the cost of accessories and production. Furthermore, the upper valve core 13 is lifted by the shaft 22 set in the lower water inlet pipe 21 to open the upper water inlet channel, making the operation simple and easy to control.

[0073] (II) The water connector of the present invention, by providing several small holes 1411 on the circular plate portion 141 of the filter screen 14, can filter out larger scale or solid particles, preventing them from entering the upper water inlet pipe 11 or the lower water inlet pipe 21 and causing blockage; by providing several large holes 1421 around the connection between the circular plate portion 141 and the enclosure portion 142, water can flow into the upper water inlet pipe 11 through the large holes 1421, avoiding the formation of a water film on the small holes 1411, which would prevent the water from flowing smoothly into the upper water inlet pipe 11. In addition, bubbles generated after the water in the upper and lower water inlet channels boils can also be discharged through the large holes 1421.

[0074] (III) When the upper water inlet pipe 11 and the lower water inlet pipe 21 are separated, the first lower valve core 24 can be driven to abut against the second sealing ring 23 under the elastic force of the first elastic member 25 to seal the second water inlet 212 of the lower water inlet channel, preventing the water remaining in the lower water inlet channel from overflowing and dripping into the base 5, and avoiding water intrusion into the electrode and causing leakage risk.

[0075] (iv) In the water connector of the present invention, when the upper water inlet pipe 11 is inserted into the lower water inlet channel, the outer side wall of the upper water inlet pipe 11 abuts against the inner side wall of the second sealing ring 23 to form a waterproof seal, preventing water leakage when the upper water inlet pipe 11 is inserted into the lower water inlet channel, and further improving the sealing performance.

[0076] (v) When the upper water inlet pipe 11 and the lower water inlet pipe 21 are separated, the water connector of the present invention can drive the shaft 22 to move upward under the elastic force of the second elastic member 29, thereby driving the second lower valve core 27 to move upward so that the third sealing ring 28 blocks the second water outlet to form a seal, preventing the water in the water pipe connected to the water outlet of the water pump 9 from flowing back into the lower water inlet channel, further improving the sealing effect and reducing the probability of water leakage in the lower water inlet assembly 2.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.
