[0021] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of an embodiment of the magnetron assembly provided by the present application.

[0022] The present application provides a magnetron assembly. As shown in Figure 1 , the magnetron assembly of the embodiment includes a magnetron device 10 and a frequency converter assembly 20. The magnetron device 10 includes a shell 101, and a first connecting structure 102 is formed on the shell 101. The first connecting structure 102 is integrally formed with the shell 101 of the magnetron, that is, the first connecting structure 102 can be formed on the shell 101 by stamping process during the production of the shell 101 of the magnetron, thereby simplifying the production process of the magnetron device 10 to save cost. The frequency converter assembly 20 includes a frequency converter 201 and a connecting piece 202, one end of the connecting piece 202 is connected to the frequency converter 201, and the other end is provided with a second connecting structure 203, and the first connecting structure 102 and the second connecting structure 203 are detachably connected. That is, when connecting the magnetron device 10 and the frequency converter 201, the second connecting structure 203 on the other end of the connecting piece 202 is inserted into the first connecting structure 202 of the shell 101 by connecting one end of the connecting piece 202 to the frequency converter 201, so that the frequency converter 201 and the shell 101 of the magnetron device 10 are coupled. The first connecting structure 102 can be a plug, that is, when connecting the frequency converter 201, the second connecting structure 203 is inserted into the plug on the edge, which effectively reduces the vibration during the installation of the magnetron device 10 and the frequency converter 201, thereby damaging the magnetron device 10. In other embodiments, the first connecting piece 202 can also be provided as a groove, so that the groove is formed on the shell 101 by stamping during the production of the shell 101, and the second connecting structure 203 of the connecting piece 202 is inserted into the groove when connecting the frequency converter 201, which can also be provided as other structures, which are not limited in the present application.

[0023] In some embodiments, when the magnetron device 10 is connected to the frequency converter 201, one end of the connecting member 202 is plugged into the frequency converter 201, and the second connecting structure 203 of the connecting member 202 is plugged into the first connecting structure 102, thereby connecting the magnetron device 10 and the frequency converter 201. When the magnetron device 10 is disassembled, the second connecting structure 203 of the connecting member 202 is pulled out of the first connecting structure 102 of the housing 101, that is, when the magnetron device 10 is installed or disassembled, the second connecting structure 203 is pulled out or plugged in, which can effectively reduce the damage to the internal components of the magnetron device 10 during installation or disassembly of the magnetron device 10. The first connecting structure 102 is formed on the housing 101, so that when the magnetron device 10 and the frequency converter 201 are used, the first connecting structure 102 forms a current loop between the second connecting structure 203 of the connecting member 202. Since the area of the first connecting structure 102 is small relative to the area of the housing 101, the electromagnetic interference can be effectively reduced when the current loop is formed between the magnetron device 10 and the frequency converter 201. Therefore, the ground of the power supply of the frequency converter 201 does not need to be directly connected to the housing 101 of the magnetron device 10 to reduce the area of the current loop and suppress the emission of electromagnetic interference.

[0024] In other embodiments, a structure of a plug can be provided on the frequency converter 201, so that when the magnetron device 10 and the frequency converter 201 are connected, the connecting member 202 can be directly plugged into the plug on the frequency converter 201, thereby reducing damage to the frequency converter 201 during connection.

[0025] In a specific application scenario, the frequency converter 201 and the magnetron device 10 are arranged inside a microwave oven, that is, the connecting member 202 connected to the frequency converter 201 is plugged into the first connecting structure 102 of the housing 101. Specifically, one end of the connecting member 202 is plugged into the frequency converter 201, and the second connecting structure 203 on the other end is plugged into the first connecting structure 102 of the housing 101, thereby completing the installation of the frequency converter 201 and the magnetron device 10. Since the cavity of the microwave oven is generally coated with paint, by plugging the second connecting structure 203 into the first connecting structure 102, the interference of the paint on the connection of the frequency converter 201 and the magnetron device 10 can be effectively reduced, thereby reducing the problem of poor contact between the loop of the magnetron device 10 and the frequency converter 201, and reducing the damage to the microwave oven caused by sparks.

[0026] In the above embodiment, by forming the first connecting structure 102 on the shell 101 of the magnetron device 10, and connecting the frequency converter 201 with the connecting piece 202, one end of the connecting piece 202 is connected with the frequency converter 201, and the other end is provided with the second connecting structure 203. When connecting the magnetron device 10 and the frequency converter 201, the second connecting structure 203 is inserted on the first connecting structure 102, so that the frequency converter 201 is coupled with the shell 101 of the magnetron device 10. On the one hand, it can reduce the damage to the magnetron device 10 when connecting the magnetron device 10 and the frequency converter 201. On the other hand, it can reduce the problem of poor contact of the current loop between the magnetron device 10 and the frequency converter 201, which reduces the risk of using the magnetron assembly.

[0027] In some embodiments, as shown in Figure 2 The opposite sides of the shell 101 are provided with openings 103, and the first connecting structure 102 is arranged at the edge position of the opening 103. That is, the two ends of the shell 101 are provided with openings 103, and the first connecting structure 102 is formed at the edge position of the opening 103 on the shell 101. In this embodiment, the first connecting structure 102 is arranged at the edge position of the opening 103, that is, the first connecting structure 102 is arranged at the four corners of the shell 101, and at least four first connecting structures 102 are arranged on the shell 101. When the magnetron device 10 is installed on the frequency converter 201, the process of connecting the magnetron device 10 and the frequency converter 201 can be simplified. By arranging the first connecting structure 102 on the edge position of the opening 103 of the shell 101, the second connecting structure 203 of the connecting piece 202 can be easily clamped on the first connecting structure 102 when connecting the frequency converter 201.

[0028] In some embodiments, the shell 101 comprises a plurality of side walls 104 connected in sequence, i.e. the shell 101 is formed by the plurality of side walls 104 to form a cylinder, the two ends of the cylinder form the openings 103, and the first connecting structure 102 is arranged on the side walls 104 on the opposite sides of the shell 101. That is, the first connecting structure 102 is arranged on the side walls 104 of the shell 101 and located at the edge position of the side walls 104 in the axial direction of the side walls 104 forming the openings 103. Among them, the plurality of side walls 104 connected in sequence have opposite left and right side walls 104, i.e. the first connecting structure 102 is arranged at the edge position of the left and right side walls 104. When connecting the magnetron device 10 to the frequency converter 201, the opposite left and right side walls 104 or the openings 103 of the shell 101 correspond to the frequency converter 201, so that at least one first connecting structure 102 corresponds to the frequency converter 201 during installation, thereby facilitating the installation of the magnetron device 10. The second connecting structure 203 of the connecting piece 202 is inserted into the first connecting structure 102, so that the shell 101 of the magnetron device 10 forms a current loop with the frequency converter 201 through the first connecting structure 102 and the connecting piece 202, thereby completing the installation of the frequency converter 201 and the magnetron device 10.

[0029] In some embodiments, two grooves 105 are formed on the edge position of the opening 103 of the shell 101, and the first connecting structure 102 is formed between the two grooves 105. That is, when the first connecting structure 102 is formed on the shell 101, two grooves 105 are stamped on the side walls 104 at the edge position of the opening 103 of the shell 101, so that the first connecting structure 102 is formed between the two grooves 105. Among them, the second connecting structure 203 adopts a terminal with a standard size of 178, in order to facilitate the insertion of the second connecting structure 203 into the first connecting structure 102, the size of the first connecting structure 102 is 0.178 inches, so that the first connecting structure 102 is adapted to the second connecting structure 203. In this embodiment, the first connecting structure 102 extends along the side walls 104 of the shell 101 in the axial direction of the opening 103, and the end of the first connecting structure 102 is parallel to the end of the side wall 104 of the shell 101 at the edge position of the opening 103, thereby facilitating the insertion of the second connecting structure 203 into the first connecting structure 102, so that the magnetron device 10 and the frequency converter 201 form a current loop through the connecting piece 202.

[0030] In other embodiments, the second connecting structure 203 can adopt other standard size terminals, and when the first connecting structure 102 is stamped on the shell 101, the size of the first connecting structure 102 is set according to the size of the second connecting structure 203, which is not limited in this application.

[0031] In an optional embodiment, the first connecting structure 102 is provided with a plug-in hole 106. That is, in the production process of the shell 101, the plug-in hole 106 can be punched on the first connecting structure 102 when the first connecting structure 102 is punched on the shell 101. The plug-in hole 106 can pass through the first connecting structure 102 or pass through part of the first connecting structure 102, so as to fix the second connecting structure 203 of the connecting piece 202 when the second connecting structure 203 is plugged into the first connecting structure 102. Among them, the plug-in hole 106 can be punched on the first connecting structure 102 after the first connecting structure 102 is punched on the shell 101, and the first connecting structure 102 and the plug-in hole 106 can also be prepared in other ways, for example, laser drilling, etc., which are not limited in the present application. In the embodiment, the shell 101 has a corresponding thickness, that is, the thickness of the second connecting structure 203 of the connecting piece 202 can be 1.4 mm, so as to adapt to the thickness of the shell 101. In the embodiment, the thickness of the shell 101 can be 1.4 mm, and the thickness of the second connecting structure 203 can be set to 1.2 mm-1.6 mm to adapt to the thickness of the shell 101, which is not limited in the present application.

[0032] In a specific application scenario, when the magnetron device 10 and the frequency converter 201 are installed in the microwave oven, the frequency converter 201 can be installed in the cavity of the microwave oven. Since the first connecting structure 102 is arranged on the shell 101 at the edge of the opening 103, when the magnetron device 10 is installed in the cavity of the microwave oven, one of the first connecting structures 102 corresponds to the frequency converter 201, so that the second connecting structure 203 of the connecting piece 202 is plugged into the first connecting structure 102, and the second connecting structure 203 is clamped on the plug-in hole 106 of the first connecting structure 102, so as to fix the second connecting structure 203 on the first connecting structure 102, so that the current loop is formed between the magnetron device 10 and the frequency converter 201.

[0033] By the above manner, the first connecting structure 102 is formed on the shell 101 of the magnetron device 10, the frequency converter 201 is connected by inserting the second connecting structure 203 of the connecting piece 202 on the first connecting structure 102, which can reduce the damage to the magnetron device 10 when connecting the magnetron device 10 and the frequency converter 201, and can solve the problem of poor circuit loop contact between the magnetron device 10 and the frequency converter 201. By opening the opening 103 on the opposite sides of the shell 101, the first connecting structure 102 can be arranged at the edge position of the opening 103, so that the second connecting structure 203 is inserted on the first connecting structure 102. The shell 101 is formed by a plurality of side walls 104 connected in sequence, and the first connecting structure 102 is arranged on the side walls 104 on the opposite sides of the shell 101, so that at least one first connecting structure 102 on the shell 101 corresponds to the frequency converter 201 when connecting the magnetron device 10 and the frequency converter 201, thereby facilitating the installation of the magnetron device 10 and simplifying the installation process. By opening two grooves 105 on the shell 101 at the edge position of the opening 103, the first connecting structure 102 is formed between the two grooves 105, which can simplify the process of preparing the first connecting structure 102 and reduce the cost. By opening the insertion hole 106 on the first connecting structure 102, the second connecting structure 203 can be connected, and the second connecting structure 203 can be fixed. By setting the size of the first connecting structure 102 to 0.178 inches, the second connecting structure 203 can be inserted on the first connecting structure 102. By setting the thickness of the second connecting structure 203 to 1.4+ / -0.2mm, the second connecting structure 203 can be adapted to the thickness of the shell 101 when the second connecting structure 203 is inserted on the first connecting structure 102.
