Description

Technical Field

[0001] The invention relates to the production and manufacturing of power distribution switch control equipment, and in particular belongs to the technical field of electric kettle base manufacturing. The invention relates to an electric kettle base connector anti-overflow testing device and method. Background Art

[0002] As a common household appliance, electric kettles are widely used in homes, offices, hotels and other places. They use electric heating elements to heat water to boiling and provide people with hot water. Electric kettles usually consist of two parts: the kettle body and the base. The base connector is a key component connecting the kettle body and the base. It is not only responsible for transmitting electrical energy to ensure the realization of the heating function, but also serves as the physical connection between the kettle body and the base. However, during the use of electric kettles, overflowing is a common and inevitable phenomenon. When overflowing water contacts the base connector, it may cause safety hazards such as short circuit, fire or electric shock. Therefore, during the manufacturing process of the electric kettle base, the electric kettle base connector needs to be tested for anti-overflow to ensure the safety of the subsequent use of the product.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] Example 1:

[0052] like Figures 1-11 As shown, an embodiment of the present invention provides an electric kettle base connector anti-overflow test device, which belongs to the production and manufacturing of distribution switch control equipment, specifically a connector anti-overflow test during the production process of the electric kettle base, which includes: a bottom box 1, an operating 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 an air supply system.

[0053] The working box 2 is installed on the top of the bottom box 1. The bottom box 1 serves as a support for supporting the working box 2, and the bottom box 1 provides installation space for the liquid collection component. In this solution, the bottom box 1 and the working box 2 are selected to have a double door or a side door or a sliding door. The bottom box 1 is provided with a liquid collection component inside. The liquid collection component is used to collect the liquid generated during the anti-overflow test (preferably a mixture of more than 15% salt water is used to make it have a higher conductivity than residential water). The coplanar portion of the working box 2 and the bottom box 1 is provided with a porous mesh plate, that is, the bottom surface of the working box 2 and the top surface of the bottom box 1 have a partial or complete overlap and are coplanar. The coplanar portion is provided with a porous mesh plate structure so that the liquid can flow downward through the porous mesh plate into the liquid collection component. The base positioning component 12 is fixedly installed on the top of the porous mesh plate, that is, the base positioning component 12 is located at the inner bottom of the working box 2. The base positioning component 12 is used to fix / position the base 13 of the electric kettle to keep the electric hot water The relative position 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 circulate 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 conducting state) under the operating conditions. The test assembly 3 can use current testing, voltage testing or resistance testing. Current testing, voltage testing or resistance testing all require external power supply. The nozzle assembly 11 is connected to the bottom of the top water tank 7 through a telescopic pipe fitting 8. Based on the telescopic pipe fitting 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, overflow often occurs above the base 13 of the electric kettle.

[0054] Specifically, the nozzle assembly 11 is a hollow disk as a whole, and a first mesh hole is provided on the bottom surface of the hollow disk. An air distribution disk 1101 is fixedly connected to the inner side of the hollow disk, and a second mesh hole is provided on the air distribution disk 1101. The air distribution disk 1101 and the inner top of the hollow disk form an annular air chamber. The air supply system is used to supply air to the annular air chamber. A plurality of rubber disks 1102 are provided on the bottom surface of the hollow disk, and the central protrusion of the rubber disk 1102 is fixedly connected to the bottom surface of the hollow disk. In this way, when there is liquid inside the hollow disk, the air supply system supplies air to the inside of the annular air chamber, and the air flow is ejected downward from the second mesh hole, stimulating the acceleration of the liquid inside the hollow disk, and ejecting the soda-water mixture (partially atomized) downward from the first mesh hole. Part of the soda-water mixture is redirected to the side by the rubber disk 1102, forming a liquid splash similar to the overflow phenomenon of the electric kettle above the base 13 of the electric kettle, and 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 component includes: a drainage member 4, which includes a mesh portion 403, a conical portion 401, and a collecting portion 402 from top to bottom. The bottom end of the collecting portion 402 is closed, and the mesh portion 403, the conical portion 401, and the collecting portion 402 are an integrated structure welded from stainless steel materials. The liquid flows downward through the porous mesh plate, and then enters the interior of the liquid collection component through the mesh portion 403, and is drained by the conical portion 401 to the interior of the collecting portion 402 for temporary storage. The conical portion 401 has a cone / prism 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, a first end of the circulating water pipe 5 is fixedly connected to the collecting part 402, and a second end of the circulating water pipe 5 is fixedly connected to the top water tank 7. A reflux pump 6 is fixedly installed on the circulating water pipe 5. When the reflux pump 6 works, the liquid inside the collecting part 402 is lifted 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 box 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 selects 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 annular air chamber of the nozzle assembly 11 is inflated. The gas flows downward through the second mesh hole opened on the gas distribution plate 1101, and the air flow drives the water flow to flow out from the first mesh hole.

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

[0059] During 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 component 301 and a resistance tester 302. The socket component 301 and the resistance tester 302 are both fixedly mounted on the outer side of the operating box 2, and the measuring contact pin of the resistance tester 302 is electrically connected to the socket component 301. The socket component 301 is designed to match the plug of the connecting wire of the electric kettle base 13. By inserting the plug of the connecting wire of the electric kettle base 13 into the socket component 301, the plug of the electric kettle base 13 and the test component 3 can be quickly electrically connected.

[0061] In one embodiment, there are multiple top water tanks 7 and nozzle assemblies 11, and the top water tanks 7 and nozzle assemblies 11 correspond one to one. A group of top water tanks 7 and nozzle assemblies 11 can test one electric kettle base 13 at a time. Designing multiple groups can improve the testing efficiency of the electric kettle base 13.

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

[0063] The annular base 1201 is fixedly installed on the top of the porous mesh plate, and a detachable screw connection method is preferably adopted. 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. The outer sleeve 1204 is sleeved on the outer side of the annular base 1201, and the outer end of the elastic limiting rod 1203 is abutted against the inner wall of the outer sleeve 1204, so that the inner end of the elastic limiting rod 1203 has an elastic limiting effect. The lining 1205 is slidably installed on the inner side of the annular base 1201 along the axial direction of the annular base 1201, and the outer side of the lining 1205 is provided with a head 1205a and a notch 1205b corresponding to the inner end of the elastic limiting rod 1203. The notch 1205b is located above the head 1205a. A plurality of claw blocks 1206 distributed in a circular array are fixedly installed on the top, and a protrusion 1206a is provided on the inner side of the claw block 1206. The inner side of the lining 1205 is fixedly connected to a central support. When the electric kettle base 13 is installed, the bottom end of the electric kettle base 13 is against the central support, and a handle 1208 is fixedly connected to the side of the lining 1205 for manipulating the lining 1205 to slide up and down. The threaded sleeve 1207 is threadedly installed on the top of the annular base 1201, and the inner side of the threaded sleeve 1207 and the outer side of the claw block 1206 form a wedge-shaped sliding portion 1206b. When the claw block 1206 slides downward, it can be synchronously pushed inward by the wedge-shaped sliding portion 1206b to deform, and the threaded sleeve 1207 is pressed on the top of the outer sleeve 1204 to limit the outer sleeve 1204 from sliding upward.

[0064] When installing the electric kettle base 13, place the electric kettle base 13 as shown in the following figure. Figure 7 1206, and the bottom of the electric kettle base 13 is against the central support. At this time, the butt 1205a of the lining 1205 is located above the elastic limiting rod 1203. The downward pressure in the process of pressing the electric kettle base 13 to pass over the bulge 1206a on the inner side of the claw block 1206 is small, and the butt 1205a cannot be pushed over the elastic limiting rod 1203. The operator continues to press the electric kettle base 13 downward. The bottom of the electric kettle base 13 presses down the central support, that is, presses down the liner 1205, so that the butt 1205a of the 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 portion 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 rests on the position of the recess 1205b. This process is the process of pressing down the electric kettle base 13 and then continuing to press down. The operator can complete the above actions continuously to achieve efficient and fast installation of the electric kettle base 13.

[0065] When disassembling the electric kettle base 13, the inner lining 1205 is lifted upward by the handle 1208, and then the electric kettle base 13 is pulled out by the wiring harness of the electric kettle base 13. The disassembly is also very convenient.

[0071] S1. Install the electric kettle base 13 in the base positioning assembly 12, and electrically connect the plug of the electric kettle base 13 to the testing assembly 3, so that the testing assembly 3 can detect the short circuit condition 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 assembly 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 to reach the nozzle assembly 11. The air supply system simultaneously supplies air to the annular air chamber of the nozzle assembly 11. The air flow is ejected downward from the second mesh, stimulating the liquid inside the hollow disk to accelerate and eject the soda-water mixture downward from the first mesh. Part of the soda-water mixture is redirected to the side by the rubber disc 1102, forming liquid splashes above the base 13 of the electric kettle, similar to the overflow phenomenon of the electric kettle, and the test component 3 detects the short circuit condition in real time.
