[0029] A magnetron is a vacuum tube that generates microwaves. It has the characteristics of high oscillation efficiency and high microwave output power, and is therefore widely used as a microwave source in microwave application equipment such as household microwave ovens and industrial microwave heating equipment.

[0030] The anode of a magnetron consists of an antenna, blades, a large cross-link, a small cross-link, and an anode cylinder. The blades need to be fixedly connected to the base of the antenna. During installation, the blades and antenna must be pre-fixed; insecure pre-fixation may cause the antenna to shift, leading to poor soldering and affecting the quality of the magnetron.

[0031] Please see Figures 1 to 3 An anode assembly 10 provided in this embodiment of the invention includes an antenna 12 and a blade 14. The antenna 12 has a first groove 16 and the blade 14 has a second groove 18. The antenna 12 and the blade 14 are nested and connected by mutual cooperation through the first groove 16 and the second groove 18. At least one of the first groove 16 and the second groove 18 has a protrusion 20 on its sidewall, so that the protrusion 20 can hold the antenna 12 on the blade 14 and / or hold the blade 14 on the antenna 12.

[0032] In the aforementioned anode assembly 10, the installation positions of the antenna 12 and the blade 14 are positioned by the first groove 16 and the second groove 18. At least one of the first groove 16 and the second groove 18 is provided with a protrusion 20 so that the antenna 12 is secured on the blade 14, thereby fixing the relative position between the antenna 12 and the blade 14 and preventing the antenna 12 from shifting and causing poor welding.

[0033] Specifically, a microwave oven is a modern cooking appliance that uses microwaves to heat food. Microwaves are a type of electromagnetic wave. A microwave oven consists of a power supply, a magnetron 100, a control circuit, and a cooking cavity. The power supply provides high voltage to the magnetron 100, which, under the excitation of the power supply, continuously generates microwaves. The magnetron 100 is connected to a stirring antenna 12 via a waveguide to transmit microwaves to the stirring antenna 12. Then, as the stirring antenna 12 rotates, it emits microwaves to various parts of the cooking cavity, heating the food inside.

[0034] The magnetron 100 is a crucial component for generating microwaves. The anode assembly 10 of the magnetron 100 consists of a metal cylinder surrounding the cathode, with blades 14 evenly distributed on the inner wall forming a resonant cavity. Under the influence of the magnetic field generated by the permanent magnet, the electrons emitted from the cathode undergo spiral motion and periodically excite a high-frequency electromagnetic field. The antenna 12 located at one end of the anode is used to extract microwave energy, which is then transmitted to the oven cavity via a waveguide system to heat the food.

[0035] The antenna 12 is connected to the blade 14 by direct insertion into the resonant cavity or by electromagnetic induction. Since the antenna 12 is in direct contact with the resonant cavity, the loss of electromagnetic energy during transmission can be reduced and the microwave extraction efficiency can be improved.

[0036] Antenna 12 achieves direct contact with the resonant cavity by connecting to blade 14. When connecting antenna 12 to blade 14, the installation position of antenna 12 must first be confirmed on blade 14 before fixing antenna 12 to blade 14. Therefore, during assembly, antenna 12 needs to be pre-fixed to blade 14 before welding.

[0037] During assembly, the antenna 12 is inserted vertically into the blade 14. The antenna 12 has a first slot 16, and the blade 14 has a second slot 18. The antenna 12 and the blade 14 are nested together by the cooperation of the first slot 16 and the second slot 18. At least one of the first slot 16 and the second slot 18 has a protrusion 20 on its sidewall, which allows the protrusion 20 to hold the antenna 12 on the blade 14 and / or to hold the blade 14 on the antenna 12.

[0038] The installation position of antenna 12 will affect the operating frequency, output power and load resistance of magnetron 100. The protrusion 20 can lock antenna 12 on blade 14 and / or lock blade 14 on antenna 12, which can limit the displacement of antenna 12 on blade 14, so that antenna 12 is installed accurately and avoids displacement of antenna 12 due to movement or collision during processing.

[0039] Optionally, in one embodiment, the protrusion 20 is disposed on the sidewall of the first slot 16. Thus, by engaging the blade 14 with the protrusion 20 on the first slot 16, the antenna 12 can be secured to the blade 14. Optionally, in one embodiment, the protrusion 20 is disposed on the sidewall of the second slot 18. Thus, by engaging the antenna 12 with the protrusion 20 on the second slot 18, the blade 14 can be secured to the antenna 12. Optionally, in one embodiment, the protrusion 20 is disposed on the sidewalls of both the first slot 16 and the second slot 18. Thus, the protrusions 20 on the first slot 16 and the second slot 18 engage with each other, securing the blade 14 and the antenna 12, thereby fixing the relative position between the antenna 12 and the blade 14.

[0040] Optionally, in one embodiment, protrusions 20 are respectively disposed on the sidewalls of the first groove 16 and the second groove 18. The protrusions 20 disposed on the blade 14 and the antenna 12 may have the same shape, or the protrusions 20 disposed on the blade 14 and the antenna 12 may have different shapes.

[0041] Optionally, in one embodiment, the protrusion 20 may be disposed on at least one sidewall of the first slot 16 or the second slot 18, thereby fixing the relative position of the antenna 12 and the blade 14. Optionally, in one embodiment, the protrusion 20 may be symmetrically disposed on two opposite sidewalls of at least one of the first slot 16 and / or the second slot 18, thereby making the force exerted by the protrusion 20 on the blade 14 more uniform, thus improving the effect of the protrusion 20 in fixing the relative position of the antenna 12 and the blade 14.

[0042] Optionally, in one embodiment, the protrusions 20 may be symmetrically arranged on the opposite two sidewalls of at least one of the first groove 16 and / or the second groove 18, and the two protrusions 20 may have the same shape or different shapes.

[0043] Please see Figures 4 to 6 In some embodiments, along the direction from the opening to the bottom of the groove, the protrusion 20 includes a first segment 22 in which the distance between the top and bottom of the protrusion gradually increases, and a second segment 24 in which the distance between the top and bottom of the protrusion gradually decreases.

[0044] In this way, the deformation of the protrusion 20 can apply a force to the blade 14, thereby fixing the relative position between the antenna 12 and the blade 14.

[0045] Specifically, the protrusion 20 includes a first segment 22 with a gradually increasing distance between its top and bottom. The first segment 22 is located close to the slot opening direction, and the distance between the top and bottom of the protrusion gradually increases. On the one hand, the first segment 22 has a guiding function when the first slot 16 and the second slot 18 are inserted and fitted together; on the other hand, the distance between the top and bottom of the first segment 22 gradually increases, while the distance between the top and bottom of the second segment 24 gradually decreases. When the protrusion 20 contacts the blade 14, the portion of the protrusion 20 with a larger distance between its top and bottom has a smaller volume and is more prone to deformation to a certain extent, making it easier for the protrusion 20 to lock onto the blade 14, thereby fixing the relative position between the antenna 12 and the blade 14.

[0046] Please see Figures 4 to 6 In some embodiments, the difference between the widest and narrowest distances within the first groove 16 and / or the second groove 18 ranges from 0 to 0.5 mm.

[0047] This ensures that the relative position between the protrusion 20 and the blade 14 is better secured.

[0048] Specifically, the widest distance within the first groove 16 and / or the second groove 18 is the groove spacing of the first groove 16 and / or the second groove 18, and the difference between the widest and narrowest distances within the first groove 16 and / or the second groove 18 is related to the maximum height of the protrusion 20. When the protrusion 20 is located on one inner sidewall of the first groove 16 and / or the second groove 18, the difference between the widest and narrowest distances is the maximum height of the protrusion 20; when the protrusion 20 is located on both inner sidewalls of the first groove 16 and / or the second groove 18, the difference between the widest and narrowest distances is the sum of the maximum heights of the protrusions 20.

[0049] Given a fixed maximum distance within the first slot 16 and / or the second slot 18, within a certain range, the greater the difference between the maximum and minimum distances within the first slot 16 and / or the second slot 18, the smaller the maximum height of the protrusion 20, and the less effective the protrusion 20 is in fixing the relative positions of the blade 14 and the antenna 12. Conversely, given a fixed maximum distance within the first slot 16 and / or the second slot 18, within a certain range, the smaller the difference between the maximum and minimum distances within the first slot 16 and / or the second slot 18, the better the protrusion 20 is in fixing the relative positions of the blade 14 and the antenna 12.

[0050] However, if the difference between the widest and narrowest distances within the first groove 16 and / or the second groove 18 is too small, it may cause the first groove 16 and the second groove 18 to fail to fit together during installation, or cause the protrusion 20 to be damaged during installation.

[0051] In summary, the range of the difference between the widest and narrowest distances within the first slot 16 and / or the second slot 18 is (0, 0.5 mm), i.e., the range of - is (0, 0.5 mm). For example, the difference between the widest and narrowest distances within the first slot 16 and / or the second slot 18 can be 0.1 mm, 0.15 mm, 0.2 mm, 0.23 mm, 0.28 mm, 0.3 mm, 0.33 mm, 0.4 mm, 0.46 mm, or 0.5 mm, or any other value within the range (0, 0.5 mm).

[0052] As shown in the figure Figures 4 to 6 As shown, in one embodiment, the protrusion 20 is disposed on the two opposite inner sidewalls of the first groove 16, the widest distance in the first groove 16, i.e. the groove pitch of the first groove 16, is A1, and the narrowest distance in the first groove 16 is A2.

[0053] Please see Figures 4 to 6 In some embodiments, the shape of the protrusion 20 includes one of trapezoidal, hemispherical, rectangular or triangular.

[0054] In this way, pressure can be generated by the deformation of the protrusion 20 to fix the relative position between the antenna 12 and the blade 14.

[0055] Specifically, when the shape of the protrusion 20 includes one of trapezoidal, hemispherical or triangular, the protrusion 20 includes a first segment 22 with the distance between the top and bottom of the protrusion gradually increasing, and a second segment 24 with the distance between the top and bottom of the protrusion gradually decreasing. When the first slot 16 and the second slot 18 are inserted and fitted together, the first segment 22 has a guiding function. At the same time, the distance between the top and bottom of the first segment 22 gradually increases, and the distance between the top and bottom of the second segment 24 gradually decreases. When the protrusion 20 contacts the blade 14, the part of the protrusion 20 with a larger distance between the top and bottom is smaller in volume and is more likely to deform to a certain extent, making it easier for the protrusion 20 to lock the blade 14, thereby realizing the fixation of the relative position between the antenna 12 and the blade 14 by the protrusion 20.

[0056] When the shape of the protrusion 20 is rectangular, the area of ​​the protrusion 20 that contacts the antenna 12 and / or the blade 14 is larger, which can make the fixing effect more reliable.

[0057] Alternatively, in one embodiment, the protrusion 20 is formed by bending the metal sheet into a trapezoidal, hemispherical, rectangular, or triangular shape.

[0058] Alternatively, in one embodiment, the protrusion 20 is integrally formed with the first groove 16 on the antenna 12 and / or the second groove 18 on the blade 14 by stamping.

[0059] In other embodiments, the protrusion 20 may have an irregular shape, and the difference between the widest distance A1 and the narrowest distance A2 within the first groove 16 or the second groove 18 may range from 0 to 0.5 mm. This allows the protrusion 20 to deform and generate pressure, thus fixing the relative position between the antenna 12 and the blade 14. Optionally, in one embodiment, the protrusion 20 may include multiple protrusions of equal height, with each protrusion contacting the antenna 12 and / or the blade 14, making the force exerted by the protrusion 20 on the antenna 12 and / or the blade 14 more uniform.

[0060] Please see Figure 3 In some embodiments, the protrusion 20 is provided on the sidewall of the first groove 16, and the groove spacing A1 of the first groove 16 is greater than or equal to the thickness D2 of the blade 14.

[0061] In this way, the first groove 16 and the second groove 18 can be more easily fitted and fixed.

[0062] Specifically, the first slot 16 and the second slot 18 are respectively through slots provided on the antenna 12 and the blade 14. The slot pitch A1 of the first slot 16 is greater than or equal to the thickness D2 of the blade 14, which makes it easier for the first slot 16 and the second slot 18 to fit and fix together.

[0063] The protrusion 20 is disposed on the side wall of the first slot 16. When the first slot 16 and the second slot 18 are fixed together, the protrusion 20 on the first slot 16 is used to fix the blade 14. Thus, the slot pitch A1 of the first slot 16 can be greater than or equal to the thickness D2 of the blade 14. When the slot pitch A1 of the first slot 16 is greater than the thickness D2 of the blade 14, the first slot 16 is easier to insert into the second slot 18. When the slot pitch A1 of the first slot 16 is equal to the thickness D2 of the blade 14, the protrusion 20 on the first slot 16 provides a better snap-fit ​​fixation effect for the antenna 12 and the blade 14.

[0064] Optionally, in one embodiment, the protrusion 20 is disposed on the sidewall of the second slot 18, and the slot pitch A3 of the second slot 18 is greater than or equal to the thickness D1 of the antenna 12. When the first slot 16 and the second slot 18 are fixed together, the protrusion 20 on the second slot 18 fixes the blade 14, thus allowing the slot pitch A3 of the second slot 18 to be greater than or equal to the thickness D2 of the blade 14. When the slot pitch A3 of the second slot 18 is greater than the thickness D2 of the blade 14, the second slot 18 is more easily inserted into the first slot 16. When the slot pitch A3 of the second slot 18 is equal to the thickness D2 of the blade 14, the protrusion 20 on the second slot 18 provides a better locking and fixing effect on the antenna 12 and the blade 14.

[0065] Optionally, in one embodiment, the protrusions 20 are respectively disposed on the sidewalls of the first slot 16 and the second slot 18, wherein the slot pitch A1 of the first slot 16 is greater than the thickness D2 of the blade 14, and the slot pitch A3 of the second slot 18 is greater than the thickness D1 of the antenna 12. Optionally, in one embodiment, the protrusions 20 are respectively disposed on the sidewalls of the first slot 16 and the second slot 18, wherein the slot pitch A1 of the first slot 16 is greater than the thickness D2 of the blade 14, and the slot pitch A3 of the second slot 18 is equal to the thickness D1 of the antenna 12. Optionally, in one embodiment, the protrusions 20 are respectively disposed on the sidewalls of the first slot 16 and the second slot 18, wherein the slot pitch A1 of the first slot 16 is equal to the thickness D2 of the blade 14, and the slot pitch A3 of the second slot 18 is greater than the thickness D1 of the antenna 12. Optionally, in one embodiment, the protrusions 20 are respectively disposed on the sidewalls of the first slot 16 and the second slot 18, the slot pitch A1 of the first slot 16 is equal to the thickness D2 of the blade 14, and the slot pitch A3 of the second slot 18 is equal to the thickness D1 of the antenna 12.

[0066] Please see Figure 2 In some embodiments, the anode assembly 10 includes an anode cylinder 26 and a plurality of blades 14. The plurality of blades 14 are disposed inside the anode cylinder 26 and arranged radially around the axis of the anode cylinder 26. One end of the blade 14 is fixedly connected to the inner sidewall of the anode cylinder 26, and the other end is suspended towards the axis of the anode cylinder 26.

[0067] Thus, the blade 14 is fixedly connected to the inner wall of the anode cylinder 26, forming a resonant cavity.

[0068] Specifically, such as Figure 2 As shown, the anode cylinder 26 assembly includes an anode cylinder 26 and a plurality of blades 14. The anode cylinder 26 is a cylindrical shape with openings at both ends. The plurality of anode blades 14 are evenly distributed in the circumferential direction on the inner wall of the anode cylinder 26, and each anode blade 14 is arranged in the radial direction along the anode cylinder 26. A resonant cavity is formed between two connected anode blades 14 and the inner wall of the anode cylinder 26.

[0069] In some embodiments, any one of the plurality of blades 14 has a second slot 18.

[0070] This makes it easier to identify the installation location of antenna 12.

[0071] Specifically, the anode assembly 10 includes multiple blades 14 of the same specifications. By opening a second slot 18 on any one of the multiple blades 14, the installation position of the antenna 12 can be determined, while avoiding any impact on the structure of other blades 14.

[0072] Optionally, in one embodiment, a second slot 18 can be formed on each blade 14, and the antenna 12 can be connected to the second slot 18 on any blade 14. In this way, multiple blades 14 can be processed using the same design size and mold, which simplifies the processing process and saves processing mold costs.

[0073] In some embodiments, the blade 14 includes a first end and a second end facing away from each other. The first end is suspended in the air facing the axis of the anode cylinder 26, and the end face of the second end is provided with a connecting layer, which connects the blade 14 to the inner wall of the anode cylinder 26.

[0074] This can significantly reduce the use of precious metal materials in welding and save on manufacturing costs.

[0075] Specifically, an electrolytic process is used to deposit a silver metal film onto the surface of the blade 14, serving as a connecting layer. During welding, the connecting layer formed by the silver metal film melts, fixing the blade 14 and the inner wall of the anode cylinder 26 together. Electroplating welding material onto the blade 14 requires less precious metal and can evenly cover the surface of the blade 14.

[0076] Alternatively, in other embodiments, when electroplating welding material on the surface of blade 14, the welding material can be made to completely cover the surface of blade 14.

[0077] In some embodiments, the anode assembly 10 further includes a first interlocking ring 28 and a second interlocking ring 30, and the blade 14 has a first mounting groove 32 and a second mounting groove 34. The first mounting groove 32 and the second mounting groove 34 are disposed opposite to each other in a first direction on the blade 14. The first interlocking ring 28 is installed in the first mounting groove 32, and the second interlocking ring 30 is installed in the second mounting groove 34.

[0078] In this way, an electrical connection can be achieved between the blades 14, forming a resonant cavity between the anode cylinder 26 and the blades 14.

[0079] Specifically, such as Figure 2As shown, the first direction is the up-down direction in the figure. The blades 14 are installed alternately in the up-down direction, that is, the first mounting groove 32 and the second mounting groove 34 are alternately arranged. The first connecting ring 28 is fixedly connected to the first mounting groove 32 every other blade 14, and the second connecting ring 30 is fixedly connected to the second mounting groove 34 every other blade 14. Thus, the first connecting ring 28 is installed on the blade 14 through the first mounting groove 32, and the second connecting ring 30 is installed on the blade 14 through the second mounting groove 34, achieving electrical connection between the blades 14 and forming a resonant cavity between the anode cylinder 26 and the blades 14.

[0080] The first mounting slot 32 and the second mounting slot 34 can be used to fix and position the first interlocking ring 28 and the second interlocking ring 30 during installation, simplifying the installation steps.

[0081] The magnetron 100 provided in the embodiments of the present invention includes the anode assembly 10 of any of the above embodiments.

[0082] The microwave cooking appliance provided by the present invention includes the magnetron 100 of the above embodiment.

[0083] In the aforementioned magnetron 100 and microwave cooking appliance, the installation positions of the antenna 12 and the blade 14 are positioned by the first groove 16 and the second groove 18.
