Description

Technical Field

[0001] This utility model belongs to the field of electric pressure cooker technology, and in particular relates to an electric pressure cooker lid-closing detection device based on a Hall switch. Background Technology

[0002] Electric pressure cookers are one of the most common kitchen appliances at present. Using electric pressure cookers can greatly reduce cooking time. Electric pressure cookers are mainly composed of three parts: the pot body, the lid, and the lid detection structure. The lid detection structure detects the lid of the pot body and the lid to ensure that the lid is in place and to prevent explosions or leaks during cooking due to the lid not being in place.

[0003] Existing document CN203609254U – "An Electric Pressure Cooker Lid Closing Detection Structure" – describes a pressure cooker lid closing detection structure. This structure includes a lid and a body support ring on the pressure cooker body that contacts the lid. It also includes a magnetic component on the side of the lid that contacts the body support ring, and a magnetic switch on the body support ring. When the lid is closed, the magnetic component and the magnetic switch are on the same vertical plane. This invention also discloses an electric pressure cooker. During the lid closing process, the magnetic switch detects whether the magnetic component is within its sensing range, i.e., whether the magnetic component and the magnetic switch are on the same vertical plane, to detect whether the lid is closed correctly. Thus, the pressure cooker is only controlled to heat when the lid is detected to be closed correctly, thereby ensuring the safety of the pressure cooker. However, it still has the following drawbacks in practical use:

[0004] 1. The above-mentioned electric pressure cooker lid detection structure uses a magnetic component mounted on the lid and a magnetic switch mounted on the corresponding position on the main body. The magnetic component is a magnet, and the magnetic switch is a reed switch. The reed switch assembly is a separate part, which has the problems of high cost and large size.

[0005] 2. The electric pressure cooker lid-closing detection structure mentioned above uses a magnet as the magnetic component and a reed switch as the magnetic sensitive component. However, during installation, the reed switch assembly must be installed first, followed by the outer cover, which is inconvenient and reduces assembly efficiency.

[0006] Therefore, the above-mentioned electric pressure cooker lid-closing detection structure cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide an electric pressure cooker lid-closing detection device based on a Hall switch. This device features a small size, light weight, long lifespan, easy installation, low power consumption, and vibration resistance. It simplifies the process of separating the switch from the outer lid, reduces costs, and improves installation efficiency, thus solving the problems mentioned above in the electric pressure cooker lid-closing detection structure.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a pressure cooker lid detection device based on Hall effect switches, including a pot body, a lower sealing plate, a lid body, and an upper sealing plate. A pot body connector is installed on the top of the side wall of the pot body, and a lower sealing plate is installed on the outer side wall of the pot body connector. The lid body is fitted onto the top of the pot body, and a lid connector is installed on the side wall of the lid body. The lid body is connected to the upper sealing plate through the lid connector. A lid handle is threaded in the upper side wall of the lid body. A Hall effect element is embedded in the inside of the first connecting plate of the pot body connector and above the lower sealing plate. A magnet is slidably inserted in the inside of the second connecting plate of the lid connector and below the upper sealing plate. An explosion-proof warning light is embedded on the outer side wall of the lower sealing plate.

[0010] The first connecting plate corresponding to the Hall element has a first storage slot, and the outer sidewall of the first storage slot is connected to the sealing plate through a limiting rod. The second connecting plate corresponding to the magnet has a second storage slot, and the outer sidewall of the second storage slot is connected to the shielding plate through a positioning rod.

[0011] Furthermore, the first connecting plate is connected to the outer wall of the pot body by the first bolt, and a first handle assembly groove is provided below the first storage groove in the first connecting plate. The first connecting plate is connected to the lower sealing plate through the first handle assembly groove.

[0012] Furthermore, the second connecting plate is connected to the outer wall of the pot lid body by the second bolt, and a second handle mounting groove is provided below the second storage groove in the second connecting plate. The second connecting plate is connected to the upper sealing plate through the second handle mounting groove.

[0013] Furthermore, mounting plates are snapped into the left and right side walls of the Hall element, and the Hall element is snapped into the first storage slot through the mounting plates, and the Hall element is electrically connected to the explosion-proof warning light.

[0014] Furthermore, the outer peripheral sidewall of the sealed plate mates with the outer wall of the first storage slot, and limit rods are inserted at both ends of the sealed plate. The limit rods are inserted from the top sidewall of the first handle assembly slot into the top inner wall of the first storage slot.

[0015] Furthermore, the outer peripheral sidewall of the baffle plate mates with the outer wall of the second storage slot, and positioning rods are inserted at both ends of the baffle plate. The positioning rods pass through the top sidewall of the second handle mounting slot and into the top inner wall of the second storage slot.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting a Hall element and a magnet, utilizes the Hall effect principle during use. When the lid of the electric pressure cooker is closed, the Hall element senses the change in magnetic field due to the influence of the magnet inside the upper sealing plate, and outputs a signal to indicate that the lid is closed. Conversely, when the lid is not closed, the Hall element does not sense the change in magnetic field and outputs a signal to the explosion-proof warning light, which flashes to remind the user that the lid is not closed. This solves the problem of the aforementioned electric pressure cooker lid detection structure, which uses a magnetic component mounted on the lid and a magnetic sensitive switch mounted at the corresponding position on the body. The magnetic component is a magnet, and the magnetic sensitive component is a reed switch. This reed switch assembly is a separate part, which is costly and bulky.

[0018] 2. This utility model features a storage groove on the connector to separately store the Hall element and the magnet. The outer side of the storage groove for storing the Hall element is connected to a sealing plate via a limiting rod, effectively sealing the Hall element. The outer side of the storage groove for storing the magnet is connected to a baffle plate via a positioning rod, effectively securing and positioning the magnet. In other words, both the Hall element and the magnet are assembled within the connectors between the pot body and the handle, and between the pot lid and the handle. The assembly method is simple, solving the problem of the aforementioned electric pressure cooker lid-closing detection structure, where the magnetic component is a magnet and the magnetic sensitive component is a reed switch. However, during installation, the reed switch assembly must be installed first, followed by the outer cover, which is inconvenient and reduces assembly efficiency. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1 and 2 As shown, this utility model is an electric pressure cooker lid-closing detection device based on a Hall switch, including a pot body 1, a lower sealing plate 3, a lid body 5, and an upper sealing plate 7. A pot body connector 2 is installed on the top of the side wall of the pot body 1, and the lower sealing plate 3 is installed on the outer side wall of the pot body connector 2. The lid body 5 is fitted onto the top of the pot body 1, and a lid connector 6 is installed on the side wall of the lid body 5. The lid body 5 is connected to the upper sealing plate 7 through the lid connector 6. The upper side wall of 5 has a threaded handle 501 for the pot lid. The handle 501 can relieve the pressure inside the pot body 1. The first connecting plate 201 in the pot body connector 2 is inlaid with a Hall element 8 above the lower sealing plate 3. The second connecting plate 601 in the pot lid connector 6 is slidably inserted with a magnet 9 below the upper sealing plate 7. An explosion-proof warning light 4 is inlaid on the outer side wall of the lower sealing plate 3. The lower sealing plate 3 can store the explosion-proof warning light 4.

[0027] The first connecting plate 201 is connected to the outer wall of the pot body 1 by the first bolt 202. The first handle mounting groove 2012 is provided below the first storage groove 2011 in the first connecting plate 201. The first connecting plate 201 is connected to the lower sealing plate 3 by the first handle mounting groove 2012 for connecting one end of the lower sealing plate 3, and they can be fixed to each other by bolts.

[0028] The second connecting plate 601 is connected to the outer wall of the pot lid body 5 by the second bolt 602. The second handle mounting groove 6011 is provided below the second storage groove 6012 in the second connecting plate 601. The second connecting plate 601 is connected to the upper sealing plate 7 by the second handle mounting groove 6011 for receiving one end of the upper sealing plate 7, and they can be fixed to each other by bolts.

[0029] Mounting plates 801 are snapped into the left and right side walls of Hall element 8, and Hall element 8 is snapped into the first storage slot 2011 through mounting plates 801. Hall element 8 is electrically connected to explosion-proof warning light 4, and explosion-proof warning light 4 can provide feedback on the information emitted by Hall element 8.

[0030] In use, the Hall element 8 employs the Hall effect principle. When the lid of the electric pressure cooker 5 is closed, it is affected by the magnet 9 inside the upper sealing plate 7. The Hall element 8 senses the change in magnetic field and outputs a signal to indicate that the lid of the electric pressure cooker 5 is closed. Conversely, when the lid of the electric pressure cooker 5 is not closed, the Hall element 8 will not sense the change in magnetic field and will output a signal to the explosion-proof warning light 4. The explosion-proof warning light 4 will flash to remind the user that the lid of the electric pressure cooker 5 is not closed.

[0031] Among them, such as Figure 1 and 3 As shown, a first storage groove 2011 is provided in the first connecting plate 201 corresponding to the Hall element 8, and the outer end sidewall of the first storage groove 2011 is connected to the sealing plate 802 through a limiting rod 803. The limiting rod 803 is used for the assembly of the sealing plate 802. A second storage groove 6012 is provided in the second connecting plate 601 corresponding to the magnet 9, and the outer end sidewall of the second storage groove 6012 is connected to the shielding plate 901 through a positioning rod 902. The positioning rod 902 is used for the assembly of the shielding plate 901.

[0032] The outer peripheral sidewall of the sealing plate 802 is fitted with the outer wall of the first storage groove 2011, and both ends of the sealing plate 802 are inserted with limit rods 803. The limit rods 803 are inserted from the top sidewall of the first handle mounting groove 2012 into the top inner wall of the first storage groove 2011. The limit rods 803 are inserted into the first storage groove 2011 from bottom to top, so that when the lower sealing plate 3 is assembled into the first handle mounting groove 2012, it can abut against the limit rods 803.

[0033] The outer periphery of the baffle plate 901 is fitted with the outer wall of the second storage groove 6012, and positioning rods 902 are inserted at both ends of the baffle plate 901. The positioning rods 902 are inserted from the top side wall of the second handle mounting groove 6011 into the top inner wall of the second storage groove 6012. The positioning rods 902 are inserted into the second storage groove 6012 from bottom to top, so that when the upper sealing plate 7 is assembled into the second handle mounting groove 6011, it can abut against the positioning rods 902.

[0034] In use, the above setup involves first inserting the Hall element 8 into the first storage slot 2011, then placing the sealing plate 802 against the outside of the Hall element 8, and inserting the limiting rod 803 from bottom to top through the top side wall of the first handle mounting slot 2012, the round holes at both ends of the sealing plate 802, and the first storage slot 2011 to complete the installation of the sealing plate 802 and the Hall element 8. Similarly, the magnet 9 is inserted into the second storage slot 6012, and the baffle plate 901 is placed against the outside of the magnet 9. The positioning rod 902 is then inserted from bottom to top through the top side wall of the second handle mounting slot 6011, the round holes at both ends of the baffle plate 901, and the second storage slot 6012 to complete the installation of the baffle plate 901 and the magnet 9.

[0035] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
