Description

Technical Field

[0001] This invention relates to the production and manufacturing of power distribution switch control equipment, specifically belonging to the field of electric kettle base manufacturing technology, and is a test device and method for preventing water overflow of electric kettle base connectors. Background Technology

[0002] Electric kettles, as a common household appliance, are widely used in homes, offices, hotels, and other places. They use electric heating elements to heat water to boiling, providing hot water for people. Electric kettles typically consist of two parts: the kettle body and the base. The base connector is a key component connecting the kettle body and the base, responsible not only for transmitting electrical energy to ensure the heating function but also for the physical connection between the kettle body and the base. However, overflowing is a frequent and unavoidable occurrence during the use of electric kettles. When overflowing water comes into contact with the base connector, it may cause safety hazards such as short circuits, fires, or electric shocks. Therefore, during the manufacturing process of electric kettle bases, overflow-proof testing of the base connector is necessary to ensure the safety of the product in subsequent use.

[0003] The authorized announcement number is CN 215494063 U. An overflow prevention testing device for electric kettle base connectors includes: a test platform, a bracket, a liquid storage tank, a liquid delivery pipe, a test pipe, a flow meter, a control valve, a base positioning ring, and a control cabinet. This device can replace manual labor in continuously testing the overflow prevention of the base connectors, effectively improving testing accuracy while reducing the workload of workers. However, in actual use, overflow from electric kettles is mostly due to boiling liquid splashing, and conventional spraying cannot adequately simulate the actual environment, resulting in insufficient testing effectiveness. Therefore, this invention provides an overflow prevention testing device and method for electric kettle base connectors. Summary of the Invention

[0035] Beneficial effects:

[0036] 1. This invention, by designing the structure of the nozzle assembly and cooperating with the air supply system to simulate the overflow phenomenon of an electric kettle, supplies air to the annular air chamber. The airflow is sprayed downward from the second mesh, which accelerates the liquid inside the hollow disc and sprays a mixture of steam and water downward from the first mesh (partially atomized). Part of the steam and water mixture is diverted to the side by the rubber disc, forming a liquid splash above the electric kettle base similar to the overflow phenomenon of an electric kettle. The short circuit condition is detected in real time by the testing component, thereby improving the testing effect.

[0037] 2. This invention, through the design of a positioning component, includes an annular base, an elastic limiting rod, an outer sleeve, an inner liner, a claw block, a central support, and a threaded sleeve. When installing the electric kettle base, the electric kettle base is inserted into the inner side of the claw block, with the bottom of the electric kettle base abutting against the central support. During the process of pressing the electric kettle base down past the protrusion on the inner side of the claw block, the downward pressure is relatively small and cannot push the abutment past the elastic limiting rod. The operator continues to press the electric kettle base down, and the bottom of the electric kettle base presses down against the central support. The claw block moves downward relative to the threaded sleeve. Under the action of the wedge-shaped sliding part, the claw block deforms inward and grasps the electric kettle base. The end of the elastic limiting rod also abuts against the recessed position. This process is the process of pressing down the electric kettle base and then continuing to press down. The operator can continuously complete the above actions, achieving efficient and rapid installation of the electric kettle base. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0051] Example 1:

[0052] like Figures 1-11 As shown, this embodiment of the invention provides an overflow prevention test device for an electric kettle base connector, which belongs to the manufacturing of power distribution switch control equipment. Specifically, it is a connector overflow prevention test during the production process of an electric kettle base. It includes: a bottom box 1, a working box 2, a liquid collection component, a base positioning component 12, a top water tank 7, a circulating water supply system, a test component 3, a nozzle component 11, and a gas supply system.

[0053] The operating chamber 2 is installed on top of the bottom chamber 1. The bottom chamber 1 serves as a support for the operating chamber 2 and provides installation space for the liquid collection assembly. In this design, both the bottom chamber 1 and the operating chamber 2 are selected to have double doors, side doors, or sliding doors. The bottom chamber 1 houses the liquid collection assembly, which collects the liquid generated during the overflow test (preferably a mixture of 15% or more salt water to give it higher conductivity than residential water). The area where the operating chamber 2 and the bottom chamber 1 are coplanar is designed with a perforated mesh plate, meaning the bottom surface of the operating chamber 2 and the top surface of the bottom chamber 1 partially or completely overlap. This perforated mesh plate structure allows the liquid to flow downwards into the liquid collection assembly. The base positioning assembly 12 is fixedly installed on top of the perforated mesh plate, located at the inner bottom of the operating chamber 2. The base positioning assembly 12 is used to fix / position the electric kettle base 13, maintaining the electric kettle's position. The relative positional relationship between the kettle base 13 and the nozzle assembly 11 meets the requirements of simulating an overflow environment. The top water tank 7 is fixedly installed on the inner top of the working box 2, and a circulating water supply system is provided between the top water tank 7 and the liquid collection assembly. The circulating water supply system is used to pump the liquid inside the liquid collection assembly into the top water tank 7. A test assembly 3 is fixedly installed on the outside of the top water tank 7. The test assembly 3 is used to test whether the connector of the electric kettle base 13 is short-circuited (whether it is in a conductive state) under the working conditions. The test assembly 3 can use current testing, voltage testing, or resistance testing. Current testing, voltage testing, or resistance testing all require an external power supply. The nozzle assembly 11 is connected to the bottom of the top water tank 7 through a telescopic tube 8. Based on the telescopic tube 8, the height of the nozzle assembly 11 relative to the base positioning assembly 12 can be adjusted up and down, and the nozzle assembly 11 is located directly above the base positioning assembly 12, that is, the overflow phenomenon mostly occurs above the electric kettle base 13.

[0054] Specifically, the nozzle assembly 11 is a hollow disc, with a first mesh opening on the bottom surface. A gas distribution plate 1101 is fixedly connected to the inner side of the hollow disc, and a second mesh opening is provided on the gas distribution plate 1101. The gas distribution plate 1101 and the inner top of the hollow disc form an annular air chamber. The air supply system is used to supply air to the annular air chamber. Multiple rubber discs 1102 are provided on the bottom surface of the hollow disc, and the central protrusion of the rubber disc 1102 is fixedly connected to the bottom surface of the hollow disc. When there is liquid inside the hollow disc, the air supply system supplies air to the annular air chamber, and the airflow is sprayed downward from the second mesh opening, which accelerates the liquid inside the hollow disc and sprays a mixture of steam and water (partially atomized) downward from the first mesh opening. Part of the steam and water mixture is diverted to the side by the rubber disc 1102, forming a liquid splash above the electric kettle base 13 similar to the overflow phenomenon of an electric kettle. The short circuit condition is detected in real time by the test component 3, thereby improving the test effect.

[0055] In one embodiment, the liquid collection assembly includes a drainage component 4, which comprises, from top to bottom, a mesh plate portion 403, a conical portion 401, and a collection portion 402. The bottom end of the collection portion 402 is closed. The mesh plate portion 403, the conical portion 401, and the collection portion 402 are integral structures welded from stainless steel. Liquid flows downward through the porous mesh plate, then through the mesh plate portion 403 into the interior of the liquid collection assembly, and is drained by the conical portion 401 to the interior of the collection portion 402 for temporary storage. The conical portion 401 has a truncated cone / pyramidal structure with a large upper part and a small lower part to ensure the drainage effect.

[0056] The circulating water supply system includes: a circulating water pipe 5, the first end of which is fixedly connected to the collection part 402, and the second end of which is fixedly connected to the top water tank 7. A return pump 6 is fixedly installed on the circulating water pipe 5. When the return pump 6 is working, it lifts the liquid inside the collection part 402 upward through the circulating water pipe 5 to the top water tank 7. The water inside the top water tank 7 flows downward by gravity and flows into the nozzle assembly 11 through the telescopic pipe fitting 8.

[0057] In one embodiment, the air supply system includes an air pump 9 and an air pipe 10. The air pump 9 is fixedly installed on the side of the bottom housing 1. One end of the air pipe 10 is connected to the air outlet of the air pump 9, and the other end of the air pipe 10 is fixedly connected to the nozzle assembly 11. The air pump 9 is a low-pressure air pump with a small flow rate. The gas generated by the air pump flows into the nozzle assembly 11 through the air pipe 10. Specifically, the gas is filled into the annular air chamber of the nozzle assembly 11. The gas flows downward through the second mesh opening on the air distribution plate 1101. The airflow pushes the water flow out from the first mesh opening.

[0058] In one embodiment, the telescopic pipe fitting 8 includes: a first pipe body 801, a second pipe body 802, and a locking sleeve 803; the bottom end of the first pipe body 801 is fixedly connected to the nozzle assembly 11, the top end of the first pipe body 801 is provided with a locking sleeve 803, the top end of the second pipe body 802 is fixedly connected to the top water tank 7, the bottom end of the second pipe body 802 is slidably disposed inside the top end of the first pipe body 801, and the first pipe body 801 and the second pipe body 802 are fixed together by the locking sleeve 803.

[0059] When in use, the user loosens the locking sleeve 803 and slides to adjust the height of the first tube 801, that is, adjusts the height of the nozzle assembly 11. After the height meets the requirements, the user tightens the locking sleeve 803 to fix the first tube 801 and the second tube 802.

[0060] In one embodiment, the test component 3 includes a socket 301 and a resistance tester 302. Both the socket 301 and the resistance tester 302 are fixedly installed on the outer side of the work box 2, and the measuring contact pin of the resistance tester 302 is electrically connected to the socket 301. The socket 301 is designed to match the plug of the electric kettle base 13 connection cable. By inserting the plug of the electric kettle base 13 connection cable into the socket 301, a quick electrical connection can be achieved between the plug of the electric kettle base 13 and the test component 3.

[0061] In one embodiment, multiple top water tanks 7 and nozzle assemblies 11 are provided, and the top water tanks 7 and nozzle assemblies 11 correspond one-to-one. One set of top water tanks 7 and nozzle assemblies 11 can test one electric kettle base 13 at a time. Designing multiple sets can improve the testing efficiency of electric kettle base 13.

[0062] In one embodiment, the positioning component 12 includes: an annular base 1201, an elastic limiting rod 1203, an outer sleeve 1204, an inner liner 1205, a claw block 1206, a central support, and a threaded sleeve 1207.

[0063] An annular base 1201 is fixedly installed on the top of the perforated mesh plate, preferably using a detachable screw connection. A side hole 1202 is provided on the side of the annular base 1201, and an elastic limiting rod 1203 is provided on the inner side of the side hole 1202. An outer sleeve 1204 is fitted onto the outer side of the annular base 1201, with the outer end of the elastic limiting rod 1203 abutting against the inner wall of the outer sleeve 1204, giving the inner end of the elastic limiting rod 1203 an elastic limiting function. An inner liner 1205 is slidably installed on the inner side of the annular base 1201 along its axial direction. The outer side of the inner liner 1205 is provided with a butt 1205a and a notch 1205b corresponding to the inner end of the elastic limiting rod 1203. The notch 1205b is located above the butt 1205a. Multiple claw blocks 1206 arranged in a ring array are fixedly installed at the top. Protrusions 1206a are provided on the inner side of the claw blocks 1206. A central support is fixedly connected to the inner side of the inner liner 1205. When the electric kettle base 13 is installed, the bottom end of the electric kettle base 13 rests on the central support. A handle 1208 is fixedly connected to the side of the inner liner 1205 for operating the inner liner 1205 to slide up and down. A threaded sleeve 1207 is threadedly installed at the top of the ring base 1201. The inner side of the threaded sleeve 1207 and the outer side of the claw blocks 1206 form a wedge-shaped sliding part 1206b. When the claw blocks 1206 slide down, they can be pushed inward by the wedge-shaped sliding part 1206b to deform. The threaded sleeve 1207 presses on the top of the outer sleeve 1204 to limit the outer sleeve 1204 from sliding up.

[0064] When installing the electric kettle base 13, align the electric kettle base 13 as follows: Figure 7 The kettle base 13 is inserted into the inner side of the claw block 1206 as shown in the diagram. Since the claw block 1206 can deform outwards, it allows the kettle base 13 to pass over the protrusion 1206a on the inner side of the claw block 1206, and the bottom of the kettle base 13 rests against the central support. At this time, the abutment 1205a of the inner liner 1205 is located above the elastic limiting rod 1203. During the process of pressing the kettle base 13 down over the protrusion 1206a on the inner side of the claw block 1206, the downward pressure is relatively small and cannot push the abutment 1205a over the elastic limiting rod 1203. The operator continues to press the kettle base 13 down. The electric kettle base 13 presses down on the center support at the bottom, that is, it presses down on the inner liner 1205, so that the abutment 1205a of the inner liner 1205 passes over the elastic limiting rod 1203. At this time, the claw block 1206 moves downward relative to the threaded sleeve 1207. Under the action of the wedge-shaped sliding part 1206b, the claw block 1206 deforms inward and grabs the electric kettle base 13. At this time, the end of the elastic limiting rod 1203 also abuts against the notch 1205b. This process is the process of pressing down on the electric kettle base 13 and then continuing to press down. The operator can continuously complete the above actions to achieve efficient and fast installation of the electric kettle base 13.

[0065] When disassembling the electric kettle base 13, simply lift the inner liner 1205 upwards using the handle 1208, and then pull out the electric kettle base 13 using the wiring harness. Disassembly is very convenient.

[0066] In one embodiment, the central support includes a central frame 1209 and a height adjustment pin 1210.

[0067] The central frame 1209 includes a central ring and multiple rods fixedly connected to the outside of the central ring. The end of the rod away from the central ring is fixedly connected to the inside of the inner liner 1205. A height adjustment pin 1210 is threaded on the top of the central ring. The top of the height adjustment pin 1210 is rounded and is used to support the bottom of the electric kettle base 13. The user can adjust the height of the top of the height adjustment pin 1210 by rotating it.

[0068] In one embodiment, the elastic limiting rod 1203 includes: a slide rod, with a ball head fixedly connected to one end of the slide rod near the inner side, the ball head being able to correspond well with the abutment 1205a and the notch 1205b, and a spring fixedly connected to one end of the slide rod near the outer side, which is generally fixed by welding, and the spring provides elastic support.

[0069] Example 2:

[0070] This embodiment provides a method for testing the overflow prevention of an electric kettle base connector, using an overflow prevention testing device for an electric kettle base connector as described in Embodiment 1, specifically including the following steps:

[0071] S1. Install the electric kettle base 13 inside the base positioning component 12, and electrically connect the plug of the electric kettle base 13 to the test component 3, so that the test component 3 can detect the short circuit status in real time.

[0072] S2. Start the circulating water supply system and the air supply system. The circulating water supply system supplies the liquid in the liquid collection component to the top water tank 7. The liquid in the top water tank 7 flows through the telescopic pipe 8 under the action of gravity and reaches the nozzle assembly 11. The air supply system simultaneously supplies air to the annular air chamber of the nozzle assembly 11. The airflow sprays downward from the second mesh, which stimulates the liquid inside the hollow disc to accelerate and spray the steam-water mixture downward from the first mesh. Part of the steam-water mixture is diverted to the side by the rubber disc 1102, forming a liquid splash above the electric kettle base 13 that is similar to the overflow phenomenon of the electric kettle. The short circuit condition is detected in real time by the test component 3.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
